ITEM 5.  OTHER EVENTS

         On June 26, 1998, Metrocall, Inc. ("Registrant" or "Metrocall")
entered into a Stock Purchase Agreement ("Stock Purchase Agreement") with AT&T
Wireless Services, Inc. ("Wireless"), McCaw Communications Companies, Inc. and
AT&T Two Way Messaging Communications, Inc. to acquire the stock of certain
subsidiaries of Wireless that operate the paging and messaging services
business of AT&T Corp. ("AT&T") and a 50KHz/50KHz Narrowband Personal
Communications Services license ("License").

         The purchase price for this acquisition is approximately $205 million,
consisting of $110 million in cash and $95 million in stated value of  a new
series of convertible preferred stock of the Registrant to be designated Series
C Convertible Preferred Stock (the "Series C Preferred").  The total purchase
price to be paid by Registrant is subject to adjustment based on the financial
performance of the acquired business prior to the closing, as described in
Article 4 of the Stock Purchase Agreement, which is attached as Exhibit 2.1
hereto.

         The Stock Purchase Agreement also provides that AT&T, Wireless and
Metrocall will enter into a Distribution Agreement on the date the transaction
closes.  Pursuant to this Distribution Agreement, Wireless will offer Metrocall
branded pagers and paging and messaging services for sale in Wireless' retail
locations on an exclusive basis for five years.  In addition, in the event
Wireless elects to offer paging and messaging services under its own brand
identity or in conjunction with other products or services, the Distribution
Agreement provides that Wireless and Metrocall will use their good faith
efforts to agree to terms and conditions under which Metrocall will provide
paging and messaging services related to implementing the offer.  Wireless and
Metrocall will also enter into eight transition services agreements, including
agreements granting Metrocall use of certain office space, transmitter sites,
terminals, billing software, and an internet gateway, as well as permitting
Wireless to phase-out use of AT&T trademarks over twelve months.

         The specific terms of the Series C Preferred will be set forth in a
Certificate of Designation, Number, Powers, Preferences and Relative,
Participating, Optional and Other Rights of Series C Convertible Preferred
Stock of Metrocall, Inc. ("Certificate of Designation") in the form of Exhibit
2.2 hereto.  Dividends will be payable in cash or additional shares of Series C
Preferred, at Registrant's option, semi-annually on outstanding shares of
Series C Preferred at an annual rate of 8% of stated value.  The Series C
Preferred will be convertible into Metrocall common stock beginning five years
after issuance.  Each share will be convertible into the number of shares of
Metrocall common stock equal to the stated value divided by $10.40, subject to
anti-dilution adjustments.  The Series C Preferred is also convertible upon
certain change of control events, as defined in the Certificate of Designation.
Metrocall will have the right to redeem the Series C Preferred beginning at the
third anniversary of  issuance, and must redeem the Series C Preferred on the
twelfth anniversary of issuance.  The Series C Preferred





                                     Page 2
<PAGE>   3
will not be transferrable for 18 months after issuance.  The Series C Preferred
will rank junior to Registrant's existing Series A Convertible Preferred Stock
and Series B Junior Convertible Preferred Stock and the future issues of senior
securities.  Metrocall will be required to register the Series C Preferred
and/or the common stock into which it is convertible pursuant to a registration
rights agreement.

         The issuance of the Series C Preferred is subject to the approval of
the Registrant's stockholders under Nasdaq rules.  If Registrant's stockholders
do not approve such issuance, AT&T may terminate the agreement and receive a $9
million termination fee from Metrocall.  Stockholders will also be asked to
approve an increase in the Registrant's authorized shares of Common Stock in
order to provide additional shares to be reserved for conversion of the Series
C Preferred.  Stockholders that beneficially own approximately 33% of
Metrocall's common stock have agreed to vote their shares in favor of the
issuance of the Series C Preferred.

         The Company expects to finance the cash portion of the consideration
from through borrowings under its bank credit facility.  Completion of the
transaction is subject to other terms and conditions, including regulatory
approvals.

         The foregoing summary of the terms of the transaction is qualified in
its entirety by reference to the Stock Purchase Agreement, form of Certificate
of Designation and the Stockholders Voting Agreements, which are included in
the Exhibits hereto.

                          (iii)   for purposes of this Section 4.2, if a
material portion of the Business is suspended, disrupted, discontinued or
interrupted during the Closing Quarter due to a Force Majeure Event and the
Operating Companies reduce their fees, make or are obligated to make a refund
of fees, or otherwise suffer a reduction in revenue or incur costs or other
damages to remedy or address the Force Majeure Event Closing Net Revenue and

to pay under this Agreement or for which Parents are fully indemnifying  Buyer,

than $19,100,000, the Purchase Price shall be decreased by the excess of the
Closing Working Capital Deficit over $19,100,000 (the "Working Capital
Adjustment").  Combined current liabilities and combined current assets shall
be calculated in accordance with GAAP, in a manner consistent with the Audited
Financial Statements; and

                          (v)     if the number of New Motorola Pagers included
in the Company's Inventory as of the Closing Date ("Closing Date Pager

means the rate published in the "Money Rates" column of The Wall Street Journal
as a guide to the Prime Rate, which is currently defined as the base rate on
corporate loans posted by at least 75% of the nation's 30 largest banks.  If a
range is published, the average rate shall be the Prime Rate.  The Prime Rate
will increase or decrease each time and as of the date the Prime Rate changes.

                          (a)     Schedule 5.1.12 contains a complete and
accurate description of all Real Property (including street address, legal
description (where known), owner, and use thereof).  Schedule 5.1.12 indicates
whether the Real Property is owned ("Owned Real Property") or leased or
licensed ("Licensed Real Property").  Schedule 5.1.12 also specifies those
premises which are now owned or leased by Parents, portions of which are

held by Operating Companies which Operating Companies reserve the right to
assign to Parents (or affiliates of Parents) prior to Closing, and those fee
title interests in real estate now owned by Operating Companies which Operating
Companies reserve the right to convey to Parents (or affiliates of Parents)
prior to Closing.  The Real Property listed on Schedule 5.1.12 includes all
interests in real property necessary to conduct the Business.

                          (b)     Except as otherwise disclosed on Schedule
5.1.12 and in the site licenses under Terminal Access Agreement, leases or
subleases under the Shared Transmitter Sites Agreement, and leases or subleases
under the Shared Office Space Agreement:

                                  (i)      The Operating Companies have good
and marketable undivided and insurable title to the Owned Real Property free
and clear of any claims, liabilities, security interests, mortgages, liens,
defects in title, pledges, conditions, charges, covenants, easements,
restrictions, encroachments, leases or encumbrances of any nature
("Encumbrances") other than (A) liens for current taxes not yet due and
payable, (B) easements, covenants, conditions, restrictions, and title defects
that, together with the Permitted Personal Property Liens, do not have a
Material Adverse Effect or that have been disclosed on Schedule 5.1.12, and (C)
liens securing indebtedness for borrowed money that Buyer or one of its
Affiliates shall elect at Closing to assume, as set forth on Schedule 5.1.12
(collectively, "Permitted Real Property Liens").

                                  (ii)     The legal descriptions for the Owned
Real Property contained in the respective deeds thereof describe the properties
fully and adequately.  All structures, facilities and improvements to the Owned
Real Property ("Structures") are located within the boundary lines of the Owned
Real Property and no structures, facilities or other improvements on any parcel
adjacent to the Owned Real Property encroach onto any portion of the Owned Real
Property except where any such encroachments, together with the Permitted Real
Property Liens and the Permitted Personal Property Liens, do not have a
Material Adverse Effect.  The Structures do not encroach on any easement which
burdens any portion of the Owned Real Property, and none of the Owned Real
Property serves any adjacent parcel for any purpose inconsistent with the use
of the Owned Real Property except where any such encroachment and or such
burden benefiting any adjacent parcel, together with the Permitted Real
Property Liens and the Permitted Personal Property Liens, does not have a
Material Adverse Effect.

                                  (iii)    The Operating Companies have valid
rights of ingress and egress to and from all Owned Real Property from and to
the public street systems for road and utility purposes.

                                  (iv)     All structures and all structural,
mechanical and other physical systems thereof that constitute part of the Owned
Real Property and all structures and all structural, mechanical and other
physical systems thereof that constitute those parts of the Leased Real
Property which the Operating Companies are obligated to maintain, repair or
replace pursuant to the provisions of the applicable lease agreements or
license agreements, including but not limited to the walls, roofs and
structural elements thereof and the heating, ventilation, air

conditioning, plumbing, electrical, mechanical, sewer, waste water, storm
water, paving and parking equipment, systems and facility included therein, and
other material items at the Real Property (collectively, the "Tangible
Assets"), are free of defects and in good operating condition and repair.  For
purposes of this Section, a defect shall mean a condition relating to the
structures or any structural, mechanical or physical system which requires an
expenditure of more than $100,000 to correct.  No maintenance or repair to the
Owned Real Property, Structures or any Tangible Asset has been unreasonably
deferred.  There is no water, chemical or gaseous seepage, diffusion or other
intrusion into said buildings, including any subterranean portions, that would
impair beneficial use of the Owned Real Property, Structures or any Tangible
Asset.

                                  (v)      All water, sewer, gas, electric,
telephone and drainage facilities, and all other utilities required by any
applicable law or by the use and operation of the Owned Real Property in the
conduct of the Business are installed to the property lines of the Owned Real
Property, are connected pursuant to valid permits to municipal or public
utility services or proper drainage facilities, are fully operable and are
adequate to service the Owned Real Property in the operation of the Business
and to permit full compliance with the requirements of all laws in the
operation of such business except where any impairment of such utility
services, together with the Permitted Real Property Liens and the Permitted
Personal Property Liens, does not have a Material Adverse Effect.  No fact or
condition exists which could result in the termination or material reduction of
access from the Real Property to roads or to sewer or other utility services
serving the Real Property except where any impairment of such access, together
with the Permitted Real Property Liens and the Permitted Personal Property
Liens, does not have a Material Adverse Effect.

                                  (vi)     The Real Property and all present
uses and operations of the Real Property comply with all applicable statutes,
rules, regulations, ordinances, orders, writs, injunctions, judgments, decrees,
awards or restrictions of any government entity having jurisdiction over any
portion of the Real Property (including, without limitation, applicable
statutes, rules, regulations, orders and restrictions relating to zoning, land
use, safety, health, employment and employment practices and access by the
handicapped) (collectively, "Laws"), covenants, conditions, restrictions,
easements, disposition agreements and similar matters affecting the Real
Property but the foregoing representation and warranty shall not apply to any
condition of non-compliance which requires the expenditure of less than
$100,000 to correct or cure.  The Operating Companies have obtained all
approvals of governmental authorities (including certificates of use and
occupancy, licenses and permits) required in connection with the construction,
ownership, use, occupation and operation of the Real Property but the foregoing
representation and warranty shall not apply to any approval, certificate of use
and occupancy, license or permit which requires the expenditure of less than
$100,000 to obtain.

                                  (vii)    Except as set forth on the surveys
previously made available to Buyer, none of the Structures, the appurtenances
thereto or the equipment therein or the operation or maintenance thereof, or
the conduct of the Business, violates any restrictive covenant or encroaches on
any property owned by others or any easement, right of way or other Encumbrance
or restriction affecting such Owned Real Property except where any such
violation





                                       18

or encroachment, together with the Permitted Real Property Liens and the
Permitted Personal Property Liens, does not have a Material Adverse Effect.

                                  (viii)   There are no pending or, to the
Parents' Knowledge, threatened condemnation, fire, health, safety, building,
zoning or other land use regulatory proceedings, lawsuits or administrative
actions relating to any portion of the Real Property or any other matters which
would have a Material Adverse Effect.

                                  (ix)     There are no parties other than the
Operating Companies in possession of any of the Real Property or any portion
thereof, and there are no leases, subleases, licenses, concessions or other
agreements, written or oral, granting to any party or parties the right of use
or occupancy of any portion of the Real Property or any portion thereof.

                                  (x)      There are no outstanding options or
rights of first refusal to purchase the Owned Real Property, or any portion
thereof or interest therein.  None of the Operating Companies has transferred
any air rights or development rights relating to the Owned Real Property.

                                  (xi)     There are no service contracts or
other agreements relating to the use or operation of the Real Property that
constitute Encumbrances.

                                  (xii)    Use of any portion of the Owned Real
Property to conduct the Business will not violate any requirement of the United
States Corps of Engineers or Laws relating to any flood plain, flood plain
district, flood hazard area, or area of similar characterization or wetlands
areas, but the foregoing representation and warranty shall not apply to any
violation which requires the expenditure of less than $100,000 to correct or
cure.

                                  (xiii)   All real property taxes and
assessments that are due and payable with respect to the Real Property have
been paid or will be paid at or prior to Closing.

                                  (xiv)    All oral or written leases,
subleases, licenses, concession agreements or other use or occupancy agreements
pursuant to which any of the Operating Companies leases from any other party
any real property, including all amendments, renewals, extensions,
modifications or supplements to any of the foregoing or substitutions for any
of the foregoing (collectively, the "Leases") are valid and in full force and
effect.  Parents have provided Buyer with access to true and complete copies of
all of the Leases, all amendments, renewals, extensions, modifications or
supplements thereto, and all material correspondence related thereto, including
all correspondence pursuant to which any party to any of the Leases declared a
default thereunder or provided notice of the exercise of any operation granted
to such party under such Lease.  The Leases and the Operating Companies'
interests thereunder are free of all Liens.

                                  (xv)     Except as set forth in Schedule
5.1.12, none of the Leases requires the consent or approval of any party
thereto in connection with the consummation of the transactions contemplated
hereby.

Conservation and Recovery Act of 1976, as amended, and the regulations
promulgated pursuant to said laws, but excluding office and janitorial supplies
properly and safely maintained (a "Hazardous Material"), are present in amounts
that either violate or reasonably could be expected to give rise to Liability
under applicable Environmental Laws in, on or under any property, including the
land and the improvements, ground water and surface water thereof, that any
Operating Company has at any time owned, operated, occupied or leased.

                          (b)     Hazardous Materials Activities.  None of the

proceeding, revocation proceeding, amendment procedure, writ, injunction or
claim is pending, or to Parents' Knowledge, threatened concerning any

There are no past or present actions, activities, circumstances, conditions,
events, or incidents that would be expected to involve the Operating Companies
(or any person or entity whose liability the Operating Companies have retained
or assumed, either by contract or operation of law) in any litigation under the
Environmental Laws, or impose upon the Operating Companies (or any person or
entity whose liability the Operating Companies have retained or assumed, either
by contract or operation of law) any environmental liability including, without
limitation, common law tort liability.

                                       41
<PAGE>   51
and 7.1.3 hereof, be placed in positions comparable to the positions held by
such employees of the Operating Companies immediately prior to the Closing
Date. Employees not listed on the side letter referred to in Section 6.12(a)
and who are on short term disability or on leave of absence on the Closing Date
shall, in addition to the requirements set forth in Sections 7.1.2 and 7.1.3
hereof, be placed in positions comparable to the positions held by such
employees of the Operating Companies immediately prior to the Closing Date, if
such  positions are available, only if such employees report for active service
with Buyer consistent with the terms set forth in Section 6.12(b).

                          (b)     (i)      A Transitioned Employee may become
eligible for certain "Transition Severance Benefits," provided that he or she
meets all requirements of Buyer's Transition Severance Pay Plan.  In general,
to be eligible for benefits under the Transition Severance Pay Plan, an
employee of the Operating Companies must be involuntarily terminated by the
Buyer prior to the end of the twelve-month period following the Closing Date,
other than for Cause, must not have refused an offer of a comparable position
of employment with Buyer, and must sign a release of employment-related claims
against the Buyer, its affiliates, and their directors, officers, employees,
and agents.  An eligible employee of the Operating Companies who meets the
requirements of the Transition Severance Pay Plan shall receive a severance
benefit equal to one month's salary, for each year of employment, taking into
account all service with Parents and Operating Companies prior to the Closing
Date as set forth on Schedule 5.1.16(b)(i), and all service with the Buyer or
any of its Affiliates after the Closing Date, up to a maximum of 6 months'
salary, less any amounts that the individual would be entitled to under the
Worker Adjustment Retraining and Notification Act.  In addition, such employee
will, upon election of health care continuation (COBRA) coverage under ERISA,
and for the number of months (not to exceed 6) equal to the number of years of
employment as described in the preceding sentence, be required to pay only that
portion of the monthly COBRA premium for which an active employee of Buyer
covered under the same health care plan would be responsible.  Subject to
Section 7.1.1(d), the definition of a "month's salary," "comparable position of
employment," and all other terms used in the Transition Severance Pay Plan
shall be as set forth in such Plan.  Parents shall reimburse Buyer for
one-half of the costs of all benefits under the Transition Severance Pay Plan
paid to, or on behalf of, any individual who was involuntarily terminated
during the six-month period immediately following the Closing Date, and who was
entitled to receive a bonus payment under either the AT&T Wireless Services
Messaging Division Group I Key Employees Bonus Plan or the AT&T Wireless
Services Messaging Division Group II Key Employees Bonus Plan (jointly referred
to as the "Parents' Completion Bonus Program").

                                  (ii)     For purposes of this Agreement,
"Cause" for termination shall mean (i) conviction (including a plea of guilty
or nolo contendere) of a crime involving violence, theft, fraud, dishonesty or
moral turpitude; (ii) intentional or negligent disclosure of confidential or
trade secret information of Buyer or Operating Companies (or any of their
Affiliates) to anyone who is not entitled to receive such information, (iii)
omission or dereliction of any statutory or common law duty of loyalty to Buyer
or Operating Companies or any of their Affiliates, (iv) violation of the
Buyer's or Operating Companies' Code of Conduct or other written policies or
procedures, or (v) repeated failure to carry out the duties of the employee's





                                       42
<PAGE>   52
position despite specific instruction to do so.  Buyer reserves the right to
determine, in its sole discretion, whether Cause exists to terminate an
employee (or otherwise take other appropriate action, which may or may not lead
to termination).

                          (c)     Each employee of the Operating Companies
eligible to participate in the Parents' Completion Bonus Plan (other than
Non-Transitioned Employees), as listed on Schedule 7.1.1(c) shall be entitled
to receive from the Plan such amounts, if any, as are payable under the Plan.

                          (d)     For purposes of Section 7.1.1(a) and (b), a
position shall be considered to be "comparable to the position held by such
employee of the Operating Companies immediately prior to the Closing Date," a
"comparable employment position," and to be a "comparable position of
employment," if  the position: (1) offers cash compensation of not less than
100% of the employee's monthly salary (excluding any target bonus opportunity,
commission or fringe benefits) which such employee of the Operating Companies
was receiving immediately prior to the Closing Date as listed on Schedule
5.1.16(b)(i) (as it may be updated) and, if applicable, an opportunity to earn
commissions; and  (2)  has duties and responsibilities which are not
significantly less than the duties and responsibilities of such employee
immediately prior to the Closing Date , and is at a work location which (i) is
not located more than 50 highway miles from such employee's current work site,
and (ii) does not add more than 50 highway miles to such employee's daily
commute, and (iii) does not result in a daily round-trip commute in excess of
100 highway miles from such employee's principal residence.

                 7.1.2    Employee Plans.

                          (a)     Parents shall retain all liabilities with
respect to benefits accrued and claims incurred with respect to all employees
of the Operating Companies under any Benefit Plan of Parents and/or Operating
Companies (but not including accrued vacation) as of the last moment of the day
before the Closing Date, or, to the extent the third sentence of Section 7.1.4
applies, as of the last moment of the last day of the month in which the
Closing occurs, including, but not limited to, with respect to individuals who
are receiving short-term disability benefits on the day prior to the closing
Date, the remainder of any short-term disability benefits to which such
individuals would be entitled under the Parents' plan (but for the transaction
set forth in this Agreement).  Except as otherwise provided in this Agreement,
as of the last moment of the Closing Date, all Transitioned Employees will
cease to participate as active employees in or accrue benefits under Parents'
Benefit Plans.  Thereafter, neither the Buyer nor any of its Affiliates nor any
employee of the Operating Companies shall assume or be entitled to participate
in any of Parents' Benefit Plans, except to the extent such plans provide by
their terms for participation after the Closing Date, Parents are required to
provide certain benefits pursuant to this Agreement, or as otherwise required
by law.  Except as otherwise expressly provided herein, Parents shall be solely
responsible for any and all costs, liabilities and obligations under any
Benefit Plan relating to any period of employment with the Operating Companies
prior to the Closing Date, whether arising as a matter of contract, Law or
otherwise.





                                       43
<PAGE>   53
                          (b)     As of the first moment of the Closing Date,
all Transitioned Employees shall be eligible to participate in the 401(k) plan
and the health and welfare benefit plans, programs and practices of the Buyer
generally applicable to other similarly-situated employees of the Buyer (the
"Buyer Plans").

                          (c)     Parents and Operating Companies will
effectuate the Transitioned Employees' participation in the Buyer's 401(k) plan
through a trustee to trustee transfer of  account balances to Buyer's 401(k)
plan upon Closing.  Buyer's  401(k) plan will be amended prior to the trustee
to trustee transfer to preserve the protected benefits of the Transitioned
Employees.

                 7.1.3    Recognition of Prior Service.    The Buyer shall
recognize, from and after the Closing Date, each Transitioned Employee's
service with the Operating Companies, as set forth on Schedule 5.1.16(b) of
this Agreement with respect to each such employee, for purposes of determining
eligibility to participate in and vesting, and, if applicable, eligibility to
commence retirement benefits, but not benefit accruals, under the 401(k) plan
in which Transitioned Employees may participate, or such other qualified
pension or profit-sharing plans maintained by Buyer or established on or after
the Closing in which Transitioned Employees participate, and for purposes of
determining eligibility to participate in, and the schedule of benefits
provided by any group health plans, vacation and other paid time-off plans and
policies, severance, disability and other welfare benefit plans established or
maintained by the Buyer or its Affiliate on or after the Closing Date;
provided, that, each Transitioned Employee will be credited with: (a) the
lesser of (1) his or her accrued sick leave under the Parents' and/or Operating
Companies' sick leave policy in effect immediately prior to the Closing Date,
or (2) 80 hours of sick leave; and (b) his or her accrued (but unused) vacation
under the Parents' and/or Operating Companies' vacation policy in effect
immediately prior to the Closing Date.  Notwithstanding the foregoing, for the
calendar year in which the Closing Date takes place, each Transitioned Employee
shall be entitled to take only the number of vacation days which he or she had
accrued during 1998, and had not used as of the Closing Date.

                 7.1.4    Health, Welfare and Fringe Benefit Plans.

                          (a)     Without limiting the scope of the Section
7.1.2(a) hereto Parents shall be responsible for all claims regarding all
injuries or illnesses occurring prior to the Closing, and shall be responsible
for providing continuation health coverage as required under Part 6 of Title I
of ERISA and Code Section 4980B with respect to any qualifying event that
occurred on or prior to the Closing Date.

                          (b)     For at least the one-year period after the
Closing Date, Buyer shall provide to all Transitioned Employees (who continue
in active employment with the Operating Companies for such entire one-year
period) medical, dental, vision care, life insurance, accidental death and
dismemberment and disability insurance benefits that are available to similarly
situated employees of the Buyer, and which shall contain no restrictions or
limitations with respect to pre-existing conditions, except to the extent any
such restrictions or limitations actually applied to such Transitioned
Employees prior to Closing Date.  Parents shall not have





                                       44
<PAGE>   54
any liabilities or obligations with respect to benefit claims under any such
Buyer Plans, or any other plans sponsored, maintained or contributed to the
Buyer for or in respect of any Transitioned Employee after the end of the day
before the Closing Date or, to the extent the following sentence applies, after
the last day of the month in which the Closing occurs.  To the extent that the
Closing takes place on a date other than the last day of a month, and as a
result, Transitioned Employees remain covered by the Parents' group health
plans through the last day of the month in which the Closing occurs, coverage
of Transitioned Employees under the corresponding group health plans of the
Buyer following the Closing shall not commence until the first day of the month
following Closing.

                          (c)     For purposes of determining whether any
Transitioned Employee or his or her covered dependents have satisfied any
required co-payments, annual deductibles and out-of-pocket maximums from and
after the Closing under the terms of the Buyer's or their Affiliate's group
health plan for the calendar year in which the Closing occurs, Transitioned
Employees and their covered dependents shall be credited with the amount of
deductibles and co-payments made by, or on behalf of, such Transitioned
Employees and their covered dependents under Parents' and/or Operating
Companies' group health plan for such year prior to the Closing Date.

                 7.1.5    Flexible Spending Arrangements.  With respect to
flexible spending arrangements in which Transitioned Employees participate, to
the extent permitted under ERISA or the Code, Parents shall continue to apply
amounts credited to the accounts of Transitioned Employees for covered medical
expenses to the extent that such expenses are incurred on or before the Closing
Date and with respect to dependent care expenses to the extent such expenses
are incurred on or before December 31, 1998.

                 7.1.6    No Solicitation.  Until the second anniversary of the
Closing Date, Parents shall not, on their own behalf or on behalf of any of
their Affiliates, directly or indirectly, solicit (with the exception of any
general solicitation of employment through some general advertising medium in
the ordinary course of business) the employment of any Transitioned Employee
who is employed by the Operating Companies, the Buyer or its Affiliate on the
date of such solicitation, and shall not employ any Transitioned Employee
included on Buyer's list of Key Employees set forth in Schedule 7.1.6.  The
foregoing restrictions shall not apply to any individual whose employment with
the Operating Companies, Buyer or its Affiliate has been involuntarily
terminated.

         7.2     WAGE AND WITHHOLDING REPORTING OBLIGATIONS.

         Parents, Operating Companies and Buyer agree that, pursuant to the
"Alternative Procedure" provided in Section 5 of Revenue Procedure 84-77,
1984-2 C.B. 753, with respect to filing and furnishing forms W-2, W-3, and 941,
(a) Parents and/or Operating Companies and Buyer shall each report on a
predecessor-successor basis as set forth therein, (b) Parents and/or Operating
Companies shall be relieved from furnishing Forms W-2 to the Transferred
Employees, and (c) Buyer shall assume the obligations of Parents and/or
Operating Companies to furnish Forms W-2 to the Transferred Employees (without
regard to the actual length of





                                       45
<PAGE>   55
employment with Buyer) for the full calendar year in which the Closing occurs.
Parents and/or Operating Companies shall fully cooperate with Buyer to allow
Buyer to fulfill its obligations hereunder.

         7.3      TAX RETURNS.

                 (a)      Parents shall (i) cause AT&T to include the Operating
Companies in its consolidated federal income Tax Returns for all Taxable
periods through and including the Closing Date; (ii) cause the Operating
Companies to be included in state and local income Tax Returns of Parents or
their Affiliates that are filed on a consolidated, combined or unitary basis
for all Taxable periods through and including the Closing Date; and (iii)
prepare or cause to be prepared and file or cause to be filed on a timely basis
all other Tax Returns that are required to be filed by or with respect to the
Operating Companies for Taxable periods ending on or before the Closing Date,
including such Tax Returns as are due after the Closing Date.  Parents shall
pay or cause to be paid all Taxes due with respect to the Tax Returns described
in the immediately preceding sentence.

                 (b)      Buyer shall prepare or cause to be prepared and file
or cause to be filed all Tax Returns of the Operating Companies for any Taxable
period that includes but does not end on the Closing Date ("Straddle Periods").
Buyer shall pay or cause to be paid all Taxes shown as due on the Tax Returns
described in the preceding sentence; provided, however, that Parents shall
reimburse Buyer, in accordance with the procedure set forth in Section
7.3(b)(i) and (b)(ii),  for the portion of any such Taxes that relates to the
portion of the Straddle Period ending on the Closing Date.

                          (i)     With respect to  any Tax Return for a
Straddle  Period, Buyer shall deliver, at least thirty (30) Business Days prior
to the due date for filling of such Tax Return (including extensions), to
Parents a statement setting forth the amount of Taxes for which Parents have a
reimbursement obligation pursuant to this Section 7.3(b) (the "Statement"), and
copies of such Tax Return.  Parents shall have the right to review and approve
or disapprove such Tax Return and Statement prior to the filing of such Tax
Return.  Parents and Buyer agree to negotiate and resolve in good faith any
issue arising as a result of the review of such Tax Return and the Statement
and mutually consent to the filling as promptly as possible of such Tax Return.
In the event the parties are unable to resolve any dispute within ten (10)
business days following the delivery of such Tax Return and the Statement,
Parents and Buyer shall jointly select a public accounting firm with nationally
recognized tax expertise ("Tax Arbitrator") to resolve the dispute.  If the Tax
Arbitrator has not resolved the dispute within five (5) business days prior to
the due date (including extensions) for the filing of the Tax Return in
question, the Buyer may file such Tax Return without Parent's consent.
Notwithstanding the filing of such Tax Return, the Tax Arbitrator shall make a
determination with respect to any disputed issue, and the amount of Taxes for
which Parents have a reimbursement obligation under this Section 7.3(b) shall
be as determined by the Tax Arbitrator.  The fees and expenses of the Tax
Arbitrator shall be shared equally by the Buyer and the Parents.





                                       46
<PAGE>   56
                 (ii)  Not later than (x) five (5) business days before the due
date for the payment of Taxes with respect to a Tax Return for a Straddle
Period or (y) in the event of a dispute, five (5) business days after notice to
Parents of resolution thereof, Parents shall pay to Buyer an amount equal to
the Taxes shown on the Statement or determined by the Tax Arbitrator as being
the responsibility of the Parents under this Section 7.3(b).  Notwithstanding
the foregoing, in the case of a dispute, Parents shall pay to Buyer not later
than five (5) business days before the due date for the payment of Taxes with
respect to such Tax Return, the amount of Taxes that Parents reasonably believe
at such time is properly the responsibility of Parents under this Section
7.3(b).  No payment pursuant to this Section 7.3(b) shall excuse Parents from
their indemnification obligations pursuant to this Agreement if the amount of
Taxes as ultimately determined (on audit or otherwise) for the periods covered
by such Tax Returns that are the responsibility of Parents exceeds the amount
of Parents' payment under this Section 7.3(b).

                 (c)      All Tax Returns for Taxable periods ending on or
before the Closing Date or for Straddle Periods shall, insofar as they relate
to any Operating Company, be prepared on a basis consistent with the last
previous such Tax Returns filed in respect of such Operating Company, unless
Parents or Buyer, as the case may be, conclude that there is no reasonable
basis for such position.

         7.4     APPORTIONMENT.

         For purposes of apportioning any Taxes to the portion of a Straddle
Period that ends on the Closing Date, the determination shall be made assuming
that there was a closing of the books as of the close of business on the
Closing Date, and, in the case of Taxes attributable to any Operating Company's
ownership of any interest in any partnership or other "flowthrough" entity, as
if the taxable period of such partnership or other "flowthrough" entity ended
as of the close of business on the Closing Date; provided, however, that real
property, personal property and intangible property Taxes shall be apportioned
ratably on a daily basis between the periods in question.

         7.5     TAX COOPERATION.

         Parents and Buyer shall, and shall cause their Affiliates to, (a)
cooperate fully, as reasonably requested, in connection with the preparation
and filing of Tax Returns pursuant to Section 7.3 and in any Tax Proceeding;
(b) make available to the other, as reasonably requested, all information,
records or documents with respect to Tax matters pertinent to the Operating
Companies for all periods ending prior to or including the Closing Date; and
(c) preserve information, records or documents relating to Tax matters
pertinent to the Operating Companies that is in their possession or under their
control until the expiration of any applicable statute of limitations or
extensions thereof, and give the other party reasonable notice and an
opportunity to take possession of such information, records or documents prior
to destroying or discarding them.

<PAGE>   57
         7.6     TAX SHARING AGREEMENTS.

         Any Tax sharing agreements or arrangements (other than this
Agreement), written or unwritten, binding any of the Operating Companies shall
be terminated as of the Closing Date and none of the Operating Companies will
as of the Closing Date have any further obligations or liabilities under such
Tax sharing agreements or arrangements.

         7.7     ALLOCATION OF PURCHASE PRICE.

         The parties have agreed that the portion of the Purchase Price that is
allocable to the 50/50 License is $30,000,000, and that the portion of the
Purchase Price that is allocable to the noncompetition covenant contained in
Section 10.5 is $20,000,000.

         7.8     TAX PROCEEDINGS.

                 (a)      If any party receives written notice from any
governmental authority of a Tax Proceeding with respect to any Tax for which
the other party is obligated to provide indemnification under this Agreement,
such party shall give prompt written notice thereof to the other party;
provided, however, that the failure to give such notice shall not affect the
indemnification provided hereunder except to the extent that the failure to
give such notice materially prejudices the indemnifying party.

                 (b)      Whenever any taxing authority sends a notice of an
audit, initiates an examination of an Operating Company or otherwise asserts a
claim, makes an assessment, or disputes the amount of Taxes (i) for any Taxable
period for which Parents are or may be liable under this Agreement, or (ii) for
any Taxable period that involves an issue that could potentially affect a
Taxable period for which Parents are or may be liable under this Agreement,
Buyer shall promptly inform Parents pursuant to the procedures in Section
7.8(a), and Parents shall have the right to control, at their cost, any
resulting Tax Proceedings and to determine whether and when to settle any such
claim, assessment or dispute to the extent such Tax Proceedings or
determinations affect the amount of Taxes for which Parents are liable under
this Agreement; provided, that Parents shall indemnify Buyer if such settlement
increases the past, present or future Tax liability of Buyer or any of its
Affiliates, or any Tax liability of any Operating Company for any Taxable
period or portion thereof beginning after the Closing Date provided that
Parents shall not be liable to indemnify Buyer pursuant to this sentence if
Parents obtain consent from Buyer for such settlement, which consent will not
be unreasonably withheld.  Whenever any taxing authority sends a notice of an
audit, initiates an examination of the Operating Companies or otherwise asserts
a claim, makes an assessment or disputes the amount of Taxes (i) for any
taxable period for which Buyer is liable under this Agreement or (ii) for any
taxable period that involves an issue that could potentially affect a taxable
period for which Buyer is or may be liable under this Agreement, Parents shall
promptly inform Buyer pursuant to the procedures in Section 7.8(a), and Buyer
shall have the right to control, at its cost, any resulting Tax Proceedings and
to determine whether and when to settle any such claim, assessment or dispute,
except to the extent such Tax Proceedings or determinations affect the amount
of Taxes for which Parents are liable under this Agreement.

<PAGE>   58
                 (c)      Parents and Buyer shall jointly control the conduct
of any Tax Proceeding relating to Taxes of any Operating Company for any
Straddle Period, and neither party shall settle such a Tax Proceeding without
the prior written consent of the other.

                 (d)      Except as otherwise provided in this Section 7.8,
Buyer shall control all Tax Proceedings relating the Operating Companies.

                 (e)      In the event that the provisions of this Section 7.8
and Sections 11.4 and 11.5 conflict or otherwise each apply by their terms,
this Section 7.8 shall exclusively govern all matters concerning Tax
Proceedings.

         7.9     FIRPTA COMPLIANCE.

         Parents shall deliver to Buyer at the Closing a certificate or
certificates in form and substance reasonably satisfactory to Buyer, duly
executed and acknowledged, certifying all facts necessary to exempt the
transactions contemplated hereunder from withholding under section 1445 of the
Code.

                          (b)     For purposes of this Agreement, "Telecom
Competitor" means the Persons set forth in a side letter between the parties,
and any other Person (other than AT&T and its Affiliates) that derives annual

based on changes in the Consumer Price Index, as adjusted by the U.S.

                 9.1.6    Stockholder Approval.  This Agreement may be
terminated by Parents if (x) Buyer's stockholders fail to approve the Proposal

                                   ARTICLE 10
                           POST-CLOSING TRANSACTIONS

         10.1    TRANSITION.

         Parents shall cooperate with Buyer, at Buyer's expense, and agree to
use their reasonable efforts to assist Buyer in a smooth transition of the
ownership of the Operating Companies on the Closing Date, including the
preservation of the continued services of employees that Buyer wishes to retain
and the preservation for Buyer of the goodwill of the Operating Companies'
suppliers, customers and others having business relations with the Operating
Companies.

         10.2    ACCESS TO BOOKS AND RECORDS.

         After the Closing, Parents shall allow representatives of Buyer
reasonable opportunity from time to time during normal business hours to
inspect and copy records which pertain to the operation of the Business prior
to the Closing Date and which are not transferred to Buyer hereunder.  After
the Closing, Buyer shall allow representatives of Parents reasonable
opportunity from time to time during normal business hours to inspect and copy
records which





                                       55
<PAGE>   65
pertain to the operation of the Business prior to the Closing Date and which
are transferred to Buyer hereunder.

         10.3    [INTENTIONALLY OMITTED.]

         10.4    CONFIDENTIALITY OF CUSTOMER LISTS.

         All documents and computer files containing the names and addresses of
the paging customers of the Operating Companies shall become Buyer's property
as of the Closing, and all copies thereof shall be turned over to Buyer, and
shall not be retained or used in whole or part by Parents or any of their
Affiliates after the Closing; provided, however, that Parents and their
Affiliates may retain any information obtained (a) by Parents and their
Affiliates in the ordinary course of business prior to the Closing which is
integrated with information related to Persons not customers of the Operating
Companies or (b) pertaining to common customers.

         10.5    NONCOMPETITION.

                 (a)      For purposes of this Agreement, the term "Restricted
Period" shall mean the period from the Closing Date until the earliest of:

                          (i)     the date that is five (5) years from the
Closing Date;

                          (ii)    a Change of Control; or

                          (iii)   the Distribution Agreement shall have been
terminated by Parents because Buyer is in material breach thereunder (other
than any such breach which is the result of a Force Majeure Event).

                 (b)      As further consideration for the transactions
contemplated hereby, neither Parent nor its Affiliates will during the
Restricted Period, for any reason whatsoever, directly or indirectly, for
itself or on behalf of or in conjunction with any other person, persons,
company, partnership, corporation or business of whatever nature, engage in any
business that involves the selling of Paging or Messaging Services anywhere in
the United States (the "Territory"), except as expressly permitted pursuant to
this Agreement or the Distribution Agreement.

                 (c)      During the Restricted Period, Parents and their
Affiliates will not, directly or indirectly, purchase the stock or assets of
any entity which derives a majority of its revenues from Paging and Messaging
Services.  If Parents or any of their Affiliates purchase the stock or assets
of an entity with a business providing Paging and Messaging Services during the
Restricted Period, they shall offer to sell such Paging and Messaging Services
business to Buyer upon such terms and conditions as Buyer and Parents may
mutually agree.  If Buyer and Parents cannot agree upon the price for such a
transaction, Parents shall obtain a valuation for the business from a
nationally recognized investment banker and offer to sell the business to Buyer
on terms and conditions in accordance with such valuation.  The cost of
obtaining such valuation shall be borne by Parents; provided, that, for any
Paging and Messaging Services business with





                                       56
<PAGE>   66
annual net revenues of less than $20,000,000, such cost shall be borne equally
by Parents, on the one hand, and Buyer, on the other hand.  Parents may operate
a Paging and Messaging Services business acquired subject to the limitations
described herein until Buyer purchases such business from Parents or, if Buyer
elects not to purchase the business from Parents, Parents may operate such
business (or sell to third parties such business) for any time thereafter.
Notwithstanding anything to the contrary, Parents and their Affiliates ("Parent
Group") may own and/or acquire, solely as an investment, securities of any
entity which is publicly traded if Parent Group does not, directly or
indirectly, beneficially own five percent (5%) or more of any class of
securities of such entity.

                 (d)      For purposes of this Agreement, "Paging and Messaging
Services" means wireless telecommunications services:

                          (i)     which use a one-way signaling path, or a
non-symmetrical two-way signal path having an inbound (i.e., return path)
signaling speed of 9.6kbps or less, and

                          (ii)    which are transmitted to portable,
battery-powered devices which devices are used solely, and not in conjunction
with other devices, to transmit and receive messages, and

                          (iii)   where messages transmitted to and from such
devices are read directly by individuals.

         The parties' intent in defining "Paging and Messaging Services" as set
forth above is to restrict Parents and their Affiliates, pursuant to this
Section 10.5, from competing in the traditional paging market.  "Paging and
Messaging Services" shall expressly exclude any paging or messaging services in
cellular, digital cellular, ESMR and/or CDPD applications, or in other services
used for the transmission of voice communications.

                 (e)      Because of the difficulty of measuring economic
losses to Buyer as a result of a breach of any of the foregoing covenants, and
because of the immediate and irreparable damage that could be caused to Buyer
for which it would have no other adequate remedy, each Parent agrees that the
foregoing covenants may be enforced by Buyers in the event of breach by such
Parent, by injunctions and restraining orders.

                 (f)      The parties agree that the foregoing covenants impose
a reasonable restraint on each Parent in light of the Business on the date of
the execution of this Agreement, assuming the completion of the transactions
contemplated hereby.

                 (g)      The covenants in this Section 10.5 are severable and
separate, and the unenforceability of any specific covenant shall not affect
the provisions of any other covenant. Moreover, in the event any court of
competent jurisdiction shall determine that the scope, time or territorial
restrictions set forth are unreasonable, then it is the intention of the
parties that such restrictions be enforced to the fullest extent which the
court deems reasonable, and the Agreement shall thereby be reformed.





                                       57
<PAGE>   67
                 (h)      It is specifically agreed that the period of five (5)
years stated at the beginning of this Section 10.5 during which the agreements
and covenants of Parents made in this Section 10.5 shall be effective, shall be
computed by excluding from such computation any time during which Parents are
found by a court of competent jurisdiction to have been in violation of any
provision of this Section 10.5. The covenants contained in this Section 10.5
shall not be affected by any breach of any other provision hereof by any party
hereto except as provided in this Section 10.5.

         10.6    INTERCOMPANY AGREEMENTS

         Except for this Agreement, the Distribution Agreement, the Transition
Agreements and the agreements set forth on Schedule 5.1.4(a), each and every
agreement, whether written or oral, in effect exclusively between one or more
of the Operating Companies, on the one hand, and one or more of the Parents or
any subsidiary of parents (other than the Operating Companies), on the other
hand, shall automatically terminate effective as of the Closing.

         10.7    PROVISION OF RECIPROCAL EMPLOYEE PLANS FOR PAGING AND CELLULAR
                 SERVICE

         Parents and Buyer each agree to reciprocally extend employee and
dependent rate plans for Paging and Messaging Services and cellular services to
existing employees on those accounts in place at Closing; provided, that, Buyer
shall not be obligated to pay for any cellular services received by employees
under such plans.  The parties' respective obligations will terminate the
earlier of (a) two years from the Closing Date or (b) upon notification of
employee's termination of employment with Parent/Buyer.


                                   ARTICLE 11
                          INDEMNIFICATION AND SURVIVAL

         11.1    INDEMNIFICATION BY PARENTS.

         Each Parent shall, jointly and severally, indemnify, defend, protect
and hold harmless Buyer and its officers, directors, employees, stockholders,
assigns, successors and Affiliates (each a "Buyer Indemnified Party" and
collectively, the "Buyer Indemnified Parties") from, against and in respect of:

                 (a)      all liabilities, losses, claims, damages, punitive
damages, causes of action, lawsuits, administrative proceedings (including
informal proceedings), investigations, audits, demands, assessments,
adjustments, judgments, settlement payments, deficiencies, penalties, fines,
interest (including interest from the date of such damages) and costs and
expenses (including without limitation reasonable attorneys' fees and
disbursements of every kind, nature and description) (collectively, "Damages")
suffered, sustained, incurred or paid by Buyer Indemnified Parties to the
extent resulting from or arising out of, directly or indirectly:

<PAGE>   68
                          (i)     any breach of any representation or warranty
of Parents set forth in this Agreement or any Schedule or certificate delivered
by or on behalf of Parents in connection herewith; or

                          (ii)    any non-fulfillment of any covenant or
agreement by Parents under this Agreement; or

                          (iii)   any liabilities of the Operating Companies
with respect to unpaid accounts payable on the Closing Date that had not been
paid within forty-five (45) days,` Litigations disclosed on Schedule 5.1.7,
other than such matters described in (a)(v) below, and liabilities not
expressly disclosed in the Financial Statements, this Agreement or the
Schedules hereto to the extent relating to the business, operations or assets
of the Operating Companies prior to the Closing Date; provided, that, Parents
shall not be liable for any such liabilities with respect to Litigations
disclosed on Schedule 5.1.7, other than such matters described in (a)(v) below,
or undisclosed liabilities which are incurred in the ordinary course of
business (e.g., liability for workers compensation claims), unless such
liabilities exceed $50,000 individually or, for such liabilities that do not
exceed $50,000, Parents shall be liable to Buyer solely to the extent they
exceed $500,000 in the aggregate; or

                          (iv)    all payments due pursuant to the terms of the

herein, all payments due pursuant to the terms of any Benefit Plan with respect
to employment prior to the Closing Date and to the extent all events requiring

the Operating Companies' operations prior to the Closing Date which constituted
Hazardous Material Activities regardless of whether such releases, Hazardous
Material Activities, or circumstances were in compliance with Environmental
Laws or were disclosed to Buyer hereunder; or

                          (vii)   any noncompliance prior to the Closing Date
by any Operating Company with applicable Environmental Laws, regardless of
whether such activities or circumstances were disclosed to Buyer hereunder; or

481(c) of the Code as a result of a





                                       59
<PAGE>   69
change in method of accounting for a Tax period ending prior to the Closing
Date or pursuant to the provisions of any agreement entered into with any
taxing authority with regard to the Tax liability of any of the Operating
Companies for any Tax period ending prior to the Closing Date; and, without
limiting any of the foregoing and for the avoidance of doubt, any liability or
other amount payable as a result of or in connection with any of the Tax
Proceedings described on Schedule 5.1.6(d).

                 (b)      [Intentionally Omitted.]

         11.2    INDEMNIFICATION BY BUYER.

         Buyer shall indemnify, defend, protect and hold harmless Parents and
their officers, directors, employees, stockholders, assigns, successors and
Affiliates (each a "Parent Indemnified Party" and collectively, the "Parent
Indemnified Parties") from, against and in respect of:

                 (a)      any and all Damages suffered, sustained, incurred or
paid by the Parent Indemnified Parties to the extent resulting from or arising
out of, directly or indirectly:

                          (i)     any breach of any representation or warranty
of Buyer in this Agreement or any Schedule or certificate delivered by or on
behalf of Buyer in connection herewith; or

                          (ii)    any non-fulfillment of any covenant or
agreement by Buyer under this Agreement; or

                          (iii)   the business, assets, operations and
activities of the Operating Companies, except for Damages against which Parents
have expressly agreed to indemnify Buyer pursuant to this Article 11.  Without
limiting Buyer's obligations under this Section 11.2(a)(iii), if, with respect
to the Interconnection Litigation set forth on Schedule 5.1.7, it is finally
adjudicated that the LECs are entitled to compensation for Dedicated
Transmission Facilities (as defined in Schedule 5.1.7), the Parents shall be
obligated to indemnify Buyer only for Damages resulting from the use of those
facilities prior to Closing.

                 (b)      [Intentionally Omitted.]

         11.3    LIMITATION.

         Notwithstanding the foregoing:

                 (a)      there shall be no liability for indemnification under
this Article 11 unless, and solely to the extent that, the aggregate amount of
Damages to Buyer Indemnified Parties on the one hand, and Parent Indemnified
Parties on the other, exceeds $500,000 (the "Indemnification Threshold");
provided, however, that the Indemnification Threshold shall not





                                       60
<PAGE>   70
apply to (i) adjustments to the Purchase Price as set forth in Sections 4.2 and
4.3;  (ii) Damages described in Sections 11.1(a)(ii)-(viii) or Sections
11.2(a)(ii) or (iii);

                 (b)      the aggregate amount of Buyer's liability on the one
hand, and Parents' liability on the other, under this Article 11 shall not
exceed $8,000,000; provided, however, that Parents' liability for Damages
described in Sections 11.1(a)(ii)-(viii) and Buyer's liability for Damages
described in Sections 11.2(a)(ii) and (iii) shall not be subject to, or count
toward, such limitation; and

                 (c)      for purposes of the indemnity in this Article 11, (i)
all representations and warranties contained in Article 5 are made without any
limitations as to materiality and (ii) the limitations set forth in Sections
11.3(a), 11.3(b) and 11.7 with respect to the representations and warranties
contained in Article 5 shall in no way limit the obligations to indemnify for
Damages described in Sections 11.1(a)(ii)-(viii) or Sections 11.2(a)(ii) and
(iii).

         11.4    CLAIMS FOR INDEMNIFICATION.

         Whenever any claim shall arise for indemnification hereunder, the
party entitled to indemnification (the "indemnified party") shall promptly
notify the other party (the "indemnifying party") of the claim and, when known,
the facts constituting the basis for such claim.  In the event of any claim for
indemnification hereunder resulting from or in connection with any claim or
legal proceedings by a third party, the notice to the indemnifying party shall
specify, if known, the amount of the liability arising therefrom.  The
indemnified party shall not settle or compromise any claim by a third party for
which it is entitled to indemnification hereunder without the prior written
consent of the indemnifying party.

         11.5    DEFENSE BY INDEMNIFYING PARTY.

         In connection with any claim giving rise to a right of indemnification
hereunder resulting from or arising out of any claim or legal proceeding by a
person who is not a party to this Agreement, the indemnifying party at its sole
cost and expense may, upon written notice to the indemnified party, assume the
defense of any such claim or legal proceeding.  The indemnified party shall be
entitled to participate in (but not control) the defense of any such action,
with its counsel and at its own expense.  If the indemnifying party does not
assume the defense of any such claim or litigation resulting therefrom, (a) the
indemnified party may defend against such claim or litigation, in such manner
as it may deem appropriate, including, but not limited to, settling such claim
or litigation with the written consent of the indemnifying party, and (b) the
indemnifying party shall be entitled to participate in (but not control) the
defense of such action, with its counsel and at its own expense.

         11.6    MANNER OF INDEMNIFICATION.

         Subject to Section 11.5 above, the obligations of the indemnifying
party hereunder shall be effected by payment of cash or delivery of a certified
or cashier's check or redemption of





                                       61
<PAGE>   71
Metrocall Preferred Stock, with accreted stated value, plus accrued dividends,
in the amount of the indemnification liability.

         11.7    SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

         All covenants and obligations to be performed after the Closing Date
contained in this Agreement or in any other certificate or document delivered
pursuant to this Agreement shall survive the Closing.  All representations and
warranties contained in this Agreement or in any other certificate or document
delivered pursuant to this Agreement shall survive the Closing for a period of
eighteen (18) months.

         11.8    INDEMNIFICATION NET OF INSURANCE AND COLLATERAL BENEFITS.

         The liability of an indemnifying party under this Agreement shall be
determined after taking into account insurance proceeds received by the
indemnified party, and no insurer of an indemnified party shall be entitled to
subrogation to the indemnified party's indemnification rights against the
indemnifying party.  In addition, the liability of an indemnifying party shall
be (a) reduced to take into account any net Tax benefit arising from the
deductibility of any Damages to which an indemnification payment relates, and,
(b) increased to take into account any net Tax cost, which does not result from
an adjustment to asset basis (whether tangible or intangible), arising from the
receipt of indemnity payments thereunder.  Any indemnification payment
hereunder shall initially be made without regard to this paragraph and shall be
reduced to reflect any net Tax benefit or increased to reflect any net Tax cost
only after the indemnified party has actually realized such benefit or such
cost.  For purposes of this Agreement, an indemnified party shall be deemed to
have actually realized a net Tax benefit or net Tax cost to the extent that,
and at such time as, the amount of Taxes payable by such indemnified party is
(i) reduced below the amount of Taxes that such Indemnified Party would have
been required to pay but for deductibility of such Damages, and (ii) increased
above the amount of Taxes that such indemnified party would have been required
to pay but for the receipt of such indemnification payments.  The amount of any
reduction or increase hereunder shall be adjusted to reflect any Final
Determination with respect to the indemnified party's liability for Taxes and,
if necessary, Parents or Buyer, as the case may be, shall make payments to the
other to reflect such adjustment.  Any indemnity payment under this Agreement
shall be treated as an adjustment to the Purchase Price for Tax purposes,
unless a Final Determination with respect to the indemnified party or any of
its Affiliates causes any such payment not to be treated as an adjustment to
the Purchase Price for U.S. federal income tax purposes.

         11.9    EXCLUSIVITY OF REMEDY.

         Parents and Buyer acknowledge that, following the Closing, this
Article 11 and the respective indemnification rights provided for herein shall,
to the extent permitted by law, be the exclusive remedy of each of them with
respect to this Agreement and the transactions contemplated hereby, except to
the extent expressly provided otherwise.

         Except as disclosed on Schedule 12.1, the transactions contemplated
hereby have been and shall be carried on by Buyer and Parents in such manner as
not to give rise to any valid claims against Parents or Buyer for a brokerage
commission, finder's fee or other like payment and each party agrees to
indemnify and hold the other harmless from and against any claims for brokerage
commissions or finder's fees insofar as such claims shall be alleged to be
based upon arrangements or agreements made by the indemnifying party or on its
behalf.  Such indemnity shall include the cost of reasonable counsel fees in
connection with the defense of any such claims.

         12.2    NOTICES.

         Except as otherwise provided, all notices which are permitted or
required under this Agreement shall be in writing and shall be deemed given (a)

         12.4    ALTERNATIVE DISPUTE RESOLUTION.

                 12.4.1   If a dispute arises out of or relating to this
Agreement or the Transition Services Agreements, the Distribution Agreement or
the Property Transition Agreements (collectively, without this Agreement, the
"Ancillary Agreements") or the transactions contemplated hereby or thereby or
the construction, interpretation, performance, breach, termination,
enforceability or validity thereof, whether such claim is based on rights,
privileges or interests recognized by or based upon contract, tort, fraud,
misrepresentation, statute, common law or any other legal or equitable theory,
and whether such claim existed prior to or arises on or after the date hereof
(a "Dispute"), the dispute resolution processes set forth in this Section 12.4
shall govern the resolution of such dispute.

                 12.4.2   If a Dispute cannot be resolved by the executives
having primary managerial responsibility for the matter to which the Dispute
pertains, the parties shall attempt in good faith to resolve such Dispute
promptly by negotiation between executives who have authority to settle the
Dispute and who are at the level of the executives who have negotiated this
Agreement ("Senior Party Representatives").

                 12.4.3   A party may provide any other party notice (a
"Dispute Notice") of any Dispute that has not been resolved in the normal
course of business.  Within ten (10) business days after delivery of the
Dispute Notice, the receiving party shall submit to each other party a response
(the "Response").  The Dispute Notice and the Response shall each include (a) a
statement setting forth the position of the party providing such notice and a
summary of arguments supporting such position, and (b) the name and title of
such party's Senior Party Representative and any other Persons who will
accompany the Senior Party Representative at the meeting at which the parties
will attempt to settle the Dispute.  Within thirty (30) business days after
delivery of the Dispute Notice, the Senior Party Representatives of the parties
shall meet at a mutually acceptable time and place, and thereafter as often as
they reasonably deem necessary, to attempt to resolve the Dispute.  All
reasonable requests for information made by one party to another will be
honored.

                 12.4.4   If the Dispute has not been resolved within fifty
(50) business days after delivery of the Dispute Notice, or if the parties fail
to meet within thirty (30) business days after delivery of the Dispute Notice,
any party may initiate arbitration of the Dispute as provided below.  If no
party initiates arbitration within sixty (60) business days after delivery of
the Dispute Notice, then the parties shall automatically be released from any
and all liability for the Dispute.

                 12.4.5   All negotiations pursuant to this Section 12.4 shall
be treated as compromise and settlement negotiations.  Nothing said or
disclosed, nor any document produced, in the course of such negotiations that
is not otherwise independently discoverable shall be offered or received as
evidence or used for impeachment or for any other purpose in any current ore
future arbitration.

<PAGE>   75
                 12.4.6   If the Dispute is not resolved as provided in
Sections 12.4.2 through 12.4.4, then any party may initiate arbitration
proceedings by providing each other party notice of such initiation of
arbitration.  The Dispute shall then be settled by arbitration in accordance
with the CPR Non-Administered arbitration Rules in effect on the date hereof,
by a panel of three arbitrators.  Each Party shall select one of the three
arbitrators and the two arbitrators so chosen shall select the third
arbitrator.  The arbitrators shall be governed by the United States Arbitration
Act, 9 U.S.C. Sections 1-16, and judgment upon the award rendered by the
arbitrators may be entered by any court having jurisdiction thereof.  The place
of arbitration shall be chosen by the three arbitrators.  The arbitrators shall
be empowered to award only damages that are recoverable under the provisions of
Article 11, and each party hereby irrevocably waives any right to recover any
other damages with respect to any Dispute.  The arbitrators shall not order
pre-hearing discovery of documents or the taking of depositions, although the
arbitrators may compel the attendance of witnesses and the production of
documents at the hearing to the extent permitted by the CPR Non-Administered
Arbitration Rules. Notwithstanding the foregoing, nothing in this Agreement
shall preclude the parties from seeking injunctive or other equitable relief
from a court with regard to any breach of this Agreement.

                 12.4.7   If a party does not provide a Dispute Notice within
one (1) year following the time the party first knows of the existence of the
acts or omissions that give rise to the Dispute, the party shall be forever
estopped from asserting the Dispute against any other party.

         12.5    ASSIGNMENT.

         This Agreement and the transactions contemplated hereby may not be
assigned or otherwise transferred, in whole or in part, by operation of law or
otherwise, without the prior written consent of the other party; provided,
however, that Buyer may assign any or all of its rights under this Agreement to
a subsidiary of Buyer but such assignment shall not release, affect or reduce
in any way Buyer's obligations to Parents hereunder.

         12.6    COUNTERPARTS.

         This Agreement may be executed in two or more counterparts, each of
which when so executed and delivered, shall be an original instrument, but such
counterparts together shall constitute a single agreement.

         12.7    ENTIRE AGREEMENT.

         This Agreement, including all Schedules and Exhibits hereto, and all
certificates and documents executed and delivered in connection with this
Agreement, when executed and delivered, together with the Confidentiality
Agreement dated November 25, 1997, constitute the entire agreement of the
parties, superseding and extinguishing all prior agreements and understandings,
representations and warranties, relating to the subject matter hereof.

         12.8    GOVERNING LAW.

         This Agreement and the rights and obligations of the parties hereunder
shall be governed by the substantive laws of the State of New York applicable
to contracts made and to be performed therein, without reference to the
principles of conflicts of laws.

         12.9    HEADINGS.

         The section and other headings contained in this Agreement are for
reference purposes only and shall not affect the meaning or interpretation of
this Agreement.

         12.10   SEVERABILITY.

         Any provision of this Agreement which is invalid or unenforceable
shall be ineffective to the extent of such invalidity or unenforceability,
provided that such invalidity or unenforceability does not deny any party the
material benefits of the transactions for which it has bargained, such
invalidity or unenforceability shall not affect in any way the remaining
provisions hereof.

         12.11   MODIFICATION AND AMENDMENT.

         This Agreement may not be modified or amended except by written
agreement specifically referring to this Agreement and signed by the parties
hereto.

         12.12   WAIVER.

         No waiver of a breach or default hereunder shall be considered valid
unless in writing and signed by the party giving such waiver, and no such
waiver shall be deemed a waiver of any subsequent breach or default of the same
or similar nature.

         12.13   PARTIES OBLIGATED AND BENEFITED.

         Subject to the limitations set forth below, this Agreement will be
binding upon the parties hereto and their respective assignees and successors
in interest and will inure solely to the benefit of such parties and their
respective assigns and successors in interest, and no other Person will be
entitled to any of the benefits conferred by this Agreement.

         12.14   RIGHTS TO SPECIFIC PERFORMANCE.

         Parents acknowledge that the unique nature of the transactions
contemplated hereby renders money damages an inadequate remedy for the breach
by Parents of their obligations under this Agreement, and Parents agree that in
the event of such breach, Buyer will, upon proper action instituted by it, be
entitled to a decree of specific performance of this Agreement in lieu of any
monetary damages for such breach.

         12.15   ACTIONS.

         Each party will execute and deliver to the other, from time to time at
or after the Closing, for no additional consideration and at no additional cost
to the requesting party, (without incurring any obligation to pay money) such
further assignments, certificates, instruments, records or other documents,
assurances or things as may be reasonably necessary to give full effect to this
Agreement and to allow each party fully to enjoy and exercise the rights
accorded and acquired by it under this Agreement.

         12.16   TERMS.

         Terms used with initial capital letters will have the meanings
specified, applicable to both singular and plural forms, for all purposes of
this Agreement.  The words "include" and "exclude" and derivatives of those
words are used in this Agreement in an illustrative sense rather than limiting
sense.

         12.17   CONSTRUCTION.

         This Agreement and the Ancillary Agreements have been negotiated by
the parties and their respective legal counsel, and legal or equitable
principles that might require the construction of this Agreement and the

drafting will not apply in any construction or interpretation hereof or
thereof.

of Parents; provided, that, Buyer and such other Persons may provide such
information (i) to lenders, subject to the same requirements of confidentiality
as set forth in this Agreement, or (ii) which is legally required to be
furnished, and provided that Buyer or such other person, as the case may be,
notifies Parents in advance of its obligation to provide such Confidential
Information and fully cooperates with Parents to protect the confidentiality of
such information.  The parties acknowledge that the Confidentiality Agreement
dated November 25, 1997 remains in full force and effect.

                 (b)      Each Parent agrees that it will, and will cause its
associates, Affiliates, officers, other personnel and authorized
representatives to, hold in strictest confidence all Confidential Information

                      SERIES C CONVERTIBLE PREFERRED STOCK

                 The powers, designations, preferences and relative,
participating, optional or other rights of the Series C Convertible Preferred
Stock of Metrocall, Inc. (the "Corporation") are as follows:


         1.      DESIGNATION AND AMOUNT.

                 This series of preferred stock shall be designated as "Series
C Convertible Preferred Stock," and shall have $0.01 par value per share.  The
number of authorized shares constituting this series shall be 25,000 shares.
Shares of the Series C Convertible Preferred Stock shall have a stated value of
$10,000.00 per share (the "Stated Value").   The Corporation may issue
fractional shares of Series C Convertible Preferred Stock.


         2.      DIVIDENDS.

                 (a)      Right to Receive Dividends.  Holders of  the Series C
Convertible Preferred Stock shall be entitled to receive, when and as declared
by the Board of Directors of the Corporation (the "Board of Directors"), to the
extent permitted by the General Corporation Law of the State of Delaware,
cumulative dividends at the rate, in the form, at the times and in the manner
set forth in this Section 2.  Such dividends shall accrue on any given share
from the day of issuance of such share and shall accrue from day to day whether
or not earned or declared, provided, that dividends shall accrue on any shares
of Series C Convertible Preferred Stock issued pursuant to Section 4.3(b) of
that certain Stock Purchase Agreement dated June 26, 1998 by and among AT&T
Wireless Services, Inc., et al. and the Corporation from the date of the
initial issuance of  Series C Convertible Preferred Stock by the Corporation
(the "Initial Issuance Date").

                  (b)     Form of Dividend. Any dividend payment made with
respect to the Series C Convertible Preferred Stock may be made, at the sole
discretion of the Board of Directors, in cash out of funds legally available
for such purpose or by issuing the number of shares of Series C Convertible
Preferred Stock equal to the amount of the dividend divided by the Stated
Value.  Any such dividend payment may be made, in the sole discretion of the
Board of Directors, partially in cash and partially in shares of Series C
Convertible Preferred Stock determined in accordance with the preceding
formula; provided, that, in the event that any such dividend payment is made
partially in cash and partially in shares of Series C Convertible Preferred
Stock, each holder of Series C Convertible Preferred Stock shall receive a
ratable amount of cash and Series C Convertible Preferred Stock that is
proportionate to the amount of Series C Convertible Preferred Stock held by
such holder on which such dividend is paid.  All shares of Series C Convertible
Preferred Stock issued as a dividend shall be fully paid and nonassessable.

                 (c)      Dividend Rate.  The dividend  rate on the Series C
Convertible Preferred Stock shall be 8% of the Stated Value per share per
annum.

                 (d)      Payment of Dividends.  Dividends shall be payable in
arrears, when and as declared by the Board of Directors, on May 15 and November
15 of each year (each such semiannual payment date a "Dividend Payment Date"),
except that if any such date is a Saturday, Sunday or legal holiday then such
dividend shall be payable on the first immediately succeeding calendar day
which is not a Saturday, Sunday or legal holiday.  Dividends shall accrue on
each share of Series C Convertible Preferred Stock as set forth in Section
2(a), and, after payment of a dividend as required hereunder, from and after
each Dividend Payment Date based on the number of days elapsed and a 365-day
year.  If a payment of a dividend as required hereunder is not made, dividends
shall accrue from the date of the last payment in full of the required
dividend.  The dividend payable on each Dividend Payment Date after issuance of
any share of Series C Convertible Preferred Stock shall be the pro rata portion
of the Dividend Rate based upon the number of days from and including the date
of issuance or the last Dividend Payment Date, as the case may be, up to and
including such Dividend Payment Date and a 365-day year.  Each dividend shall
be paid to the holders of record of shares of the Series C Convertible
Preferred Stock as they appear on the books of the Corporation on such record
date, not more than 45 days nor fewer than 10 days preceding the respective
Dividend Payment Date, as shall be fixed by the Board of Directors.

                 (e)      Dividend Preference.  Dividends in cash on the Series
C Convertible Preferred Stock shall be payable after dividends are paid on the
Series A Convertible Preferred Stock, $.01 par value, of the Corporation (the
"Series A Preferred Stock"), on the Series B Junior Convertible Preferred
Stock, $.01 par value of the Corporation (the "Series B Preferred Stock"), and
on any other class or series of preferred stock of the Corporation that by its
terms is senior to the Series C Convertible Preferred Stock in right of payment
of dividends or liquidation preference (together with the Series A Preferred
Stock and the Series B Preferred Stock, "Senior Stock") and before any
dividends or distributions or other payments shall be paid or set aside for
payment upon the Common Stock or any other stock ranking on liquidation or as
to dividends or distributions junior to the Series C Convertible Preferred
Stock (any such stock, together with the Common Stock, being referred to
hereinafter as "Junior Stock"), other than a dividend, distribution or payment
paid solely in shares of Common Stock or other Junior Stock that is not
Redeemable Stock.  If at any time dividends on the outstanding Series C
Convertible Preferred Stock at the rate set forth herein shall not have been
paid or declared and set apart for payment with respect to all preceding and
current periods, the amount of the deficiency shall be fully paid or declared
and set apart for payment, before any dividend, distribution or payment shall
be declared or paid upon or set apart for the shares of any class of Junior
Stock, other than a dividend, distribution or payment paid solely in shares of
Common Stock or other Junior Stock that is not Redeemable Stock.  The term
"Redeemable Stock" shall mean any equity security that by its terms or
otherwise is required to be redeemed for cash on or prior to the Final
Redemption Date (as defined in Section 7) or is redeemable for cash at the
option of the holder thereof at any time prior to the Final Redemption Date.

                 If there shall be outstanding shares of any Parity Securities
(as defined below), no full dividends shall be declared or paid or set apart
for payment on any such Parity Securities for any period unless full cumulative
dividends have been or contemporaneously are declared and paid or




                                     - 2 -
<PAGE>   4
declared and a sum or additional shares of Series C Convertible Preferred Stock
as permitted hereunder sufficient for the payment thereof set apart for such
payment on the Series C Convertible Preferred Stock for all dividend periods
terminating on or prior to the date of payment of such dividends; provided that
in no event shall any dividends be declared or paid in cash on Parity
Securities unless dividends in cash of not less than a ratable amount are
declared and paid on Series C Convertible Preferred Stock.  The term "Parity
Securities" shall mean any class or series of capital stock which is entitled
to share ratably with the Series C Convertible Preferred Stock in the payment
of dividends, including accumulations, if any, and, in the event that the
amounts payable thereon on liquidation are not paid in full, are entitled to
share ratably with the Series C Convertible Preferred Stock in any distribution
of assets; provided that Parity Securities shall not include any shares of
Series C Convertible Preferred Stock issued as dividends pursuant to this
Section 2.

                 If dividends on the Series C Convertible Preferred Stock and
on any other series of Parity Securities are in arrears, in making any dividend
payment on account of such arrears, the Corporation shall make payments ratably
(and ratably as to cash, in-kind or other payments) upon all outstanding shares
of the Series C Convertible Preferred Stock and shares of such other Parity
Securities in proportion to the respective aggregate amounts of dividends in
arrears on the Series C Convertible Preferred Stock and on such other series of
Parity Securities to the date of such dividend payment.

                 (f)      Common Stock Dividends.  If prior to ______, 2003
[fifth anniversary of closing], the Corporation pays or sets aside for payment
any dividend or distribution on the Common Stock (a "Common Stock Dividend")
(other than dividends or distributions paid solely in shares of Common Stock or
of rights, options or warrants to purchase Common Stock), the Series C
Convertible Preferred Stock will be entitled to receive Common Stock Dividends,
as and when paid on the Common Stock, in an amount per share equal to (i) the
Accreted Stated Value (as defined below) per share divided by the Conversion
Price, times (ii) the amount of the Common Stock Dividend payable per share of
Common Stock. Any Common Stock Dividend shall be paid to the holders of record
of shares of the Series C Convertible Preferred Stock as they appear on the
books of the Corporation on such record date as shall be fixed by the Board of
Directors for the payment of the Common Stock Dividend.   If the Corporation
declares any Common Stock Dividend on or after ____________, 2003 [fifth
anniversary of closing], the Corporation will provide notice of the record date
for such dividend to the holders of record of shares of the Series C
Convertible Preferred Stock as they appear on the books of the Corporation,
such notice to be provided no later than at least fifteen (15) business days
prior to the record date and no later than the date on which the Corporation is
required to give notice of the record date for such dividend under Rule 10b-17
of the Securities and Exchange Commission or any successor rule or applicable
law.


         3.      LIQUIDATION PREFERENCE.

                 In the event of any bankruptcy, liquidation, dissolution or
winding up of the Corporation, either voluntary or involuntary, each holder of
Series C Convertible Preferred Stock at the time thereof shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
funds of the Corporation to the holders of the Common Stock or other Junior
Stock by





                                     - 3 -
<PAGE>   5
reason of their ownership of such stock, but after payment to holders of the
Senior Stock of any amounts to which they are entitled, an amount per share of
Series C Convertible Preferred Stock equal to the Stated Value plus any accrued
and unpaid dividends to the date of liquidation.  If the assets and funds
legally available for distribution among the holders of Series C Convertible
Preferred Stock shall be insufficient to permit the payment to the holders of
the full  preferential amount, then the assets and funds shall be distributed
ratably among holders of Series C Convertible Preferred Stock in proportion to
the number of shares of Series C Convertible Preferred Stock owned by each
holder.  If any Parity Securities are outstanding, and the assets and funds
legally available for distribution among the Series C Convertible Preferred
Stock and the Parity Securities shall be insufficient to permit the payment to
holders of Series C Convertible Preferred Stock the full  preferential amount
and the preferential amount payable upon liquidation to any outstanding Parity
Securities, the holders of Series C Convertible Preferred Stock and the holders
of such other Parity Securities shall share ratably (and ratably as to cash or
other distributions) in any distribution of assets of the Corporation in
proportion to the full respective preferential amounts to which they are
entitled.


         4.      VOTING RIGHTS.

                 The  holders of the Series C Convertible Preferred Stock shall
have no voting rights except as set forth in the Corporation's Amended and
Restated Certificate of Incorporation, as it may be amended or restated from
time to time (the "Certificate of Incorporation") or as provided by applicable
law, and except for the following:

                 (a)      Changes in Organizational Documents.  So long as the
Series C Convertible Preferred Stock is outstanding, the Corporation shall not,
without first obtaining the affirmative vote or written consent of the holders
of a majority of  the then outstanding shares of Series C Convertible Preferred
Stock, voting as a single class, amend, repeal, modify or supplement (i) any
provision of the Certificate of  Incorporation or the Bylaws of the
Corporation, each as in effect on the Initial Issuance Date, or any successor
bylaws, if such amendment, repeal, modification or supplement in any way
adversely affects the powers, designations, preferences or other rights of the
Series C Convertible Preferred Stock, provided, that nothing contained herein
shall be construed to prohibit the Corporation from issuing any debt or equity
securities, regardless of ranking, or (ii) this Certificate of Designation,
Number, Powers, Preferences and Relative, Participating, Optional and Other
Rights of Series C Convertible Preferred Stock ("Certificate of Designation").

                 (b)      Means of Voting. The rights of the holders of Series
C Convertible Preferred Stock under this Section 4 may be exercised (i)  at a
meeting of the holders of shares of such Series C Convertible Preferred Stock,
called for the purpose by the Corporation; or (ii) by written consent signed by
the holders of the requisite percentage of the then outstanding shares of the
Series C Convertible Preferred Stock, delivered to the Secretary or Assistant
Secretary of the Corporation. Except to the extent otherwise provided herein or
to the extent that holders of a majority of the Series C Convertible Preferred
Stock decide otherwise, any meeting of the holders of  Series C Convertible
Preferred Stock shall be conducted in accordance with the provisions of the
By-Laws of the Corporation applicable to meetings of stockholders.  In the
event of a conflict or inconsistency

between the By-Laws of the Corporation and any term of this Certificate of
Designation, including, but not limited to this Section 4, the terms of this

2003 [fifth anniversary of closing] (except as to any shares which shall have

less than all, of the shares of Series C Convertible Preferred Stock held by

to the Accreted Stated Value of the shares converted divided by the Conversion
Price, provided, that in the event that on or after ________, 2003 the
Corporation delivers a  notice  of redemption of Series C Convertible Preferred
Stock pursuant to Section 6(c), the right to convert may be exercised with
respect to shares of Series C Convertible Preferred Stock called for redemption
in such notice only during the period ending fifteen (15) days prior to the

                 (b)      Change of Control.  (i)   If a Change of Control

of shares of Series C Convertible Preferred Stock may, at its option, at times
specified below, convert all, but not less than all, such shares held by such
holder into the number of fully paid and nonassessable shares of Common Stock
determined by dividing (x) the Stated Value multiplied by the number of shares
surrendered plus any accrued but unpaid dividends on such shares by (y) the

         ordinarily having the right to vote in the election of directors;

<PAGE>   7

                                  (C)      any sale, lease, exchange or other
         transfer (in one transaction or a series of related transactions) of
         all, or substantially all, the assets of the Corporation to any
         Beneficial Owner (other than any wholly owned subsidiary of the
         Corporation);

                                  (D)      the merger or consolidation of the
         Corporation with or into another corporation or the merger of another
         corporation into the Corporation with the effect that immediately
         after such transaction any Beneficial Owner shall have become the
         beneficial owner of securities of the surviving corporation of such
         merger or consolidation representing a majority of the combined voting
         power of the outstanding securities of the surviving corporation
         ordinarily having the right to vote in the election of directors; or

                                  (E)      the adoption of a plan leading to
         the liquidation or dissolution of the Corporation;

         holders notice pursuant to Section 5(g) of a Change of Control within
         five business days after the occurrence of such Change of Control.
         Except as set forth in Section 5(b)(iii)(B), the right to convert set
         forth in this Section 5(b) shall be exercised by any holder only
         within 10 business days after such notice has been given of the
         occurrence of the Change of Control.

                                  (B)      If the Corporation agrees to enter
         into a transaction that, when consummated, would result in a Change of
         Control defined in Sections 5(b)(ii)(C) or (D), the Corporation shall
         give notice to the holders of such transaction at least 15 business
         days prior to the consummation of the transaction, and the holders
         may, within 10 business days after the date of such notice, exercise
         the right to convert the Series C Convertible Preferred Stock into
         Common Stock, such conversion to take effect at or immediately prior
         to the record date for holders of Common Stock to receive the

         by the Corporation given to holders pursuant to the preceding sentence
         and (y) the value of the consideration per share of Common Stock
         (determined by the Board of Directors, in good faith, as of the date
         of the first public announcement of the transaction) to be paid to
         holders of Common Stock in the transaction times 1.1, provided, that
         in no event shall the Conversion Price for this purpose be less than

         Agreement between the Corporation and The First National Bank of
         Boston dated as of November 15, 1996, which adjustment provisions are
         substantially similar to the adjustment provision in 5(i)).  For
         purposes hereof, a "Going Private Transaction" shall mean a Change of
         Control defined in Sections 5(b)(ii) (C) or (D), as a result of which,
         immediately after consummation of such transaction, the securities
         into which the Series C Convertible Preferred Stock would be
         convertible are not listed on a national securities exchange or the
         NASDAQ National Market System or, even if such securities are so
         listed,  the number of issued and outstanding shares of such
         securities (excluding (x) shares owned by any beneficial owner of  a
         majority of such shares and (y) "restricted" shares within the meaning
         of Rule 144 under the Securities Act





                                     - 6 -
<PAGE>   8
         of 1933, or any successor rule [that have not been held for the
         requisite holding period under Rule 144(d)]) is less than three (3)
         times the number of shares into which all outstanding shares of the
         Series C Convertible Preferred Stock would be convertible after giving
         effect to the transaction.

                 (c)      Conversion Price.  The Conversion Price of the shares
of Series C Convertible Preferred Stock shall be $10.40, adjusted as set forth
herein.

                 (d)      Common Stock.  The Common Stock to be issued upon
conversion hereunder shall be fully paid and nonassessable.

                 (e)      Procedures for Conversion.  (i)  In order to convert
shares of Series C Convertible Preferred Stock into shares of Common Stock, the
holder shall surrender the certificate or certificates therefore, duly endorsed
for transfer, at any time during normal business hours, to the Corporation at
its principal or at such other office or agency then maintained by it for such
purpose (the "Payment Office"), accompanied (or preceded as required by Section
5(a)) by written notice to the Corporation of such holder's election to convert
and (if so required by the Corporation or any conversion agent) by an
instrument of transfer, in form reasonably satisfactory to the Corporation and
to any conversion agent, duly executed by the registered holder or by his duly
authorized attorney, and any cash payment required pursuant to Section
5(e)(iii).   As promptly as practicable after the surrender for conversion of
any share of the Series C Convertible Preferred Stock in the manner provided in
the preceding sentence, and the payment in cash of any amount required by the
provisions of Section 5(e)(iii), but in any event within three Trading Days of
such surrender for payment, the Corporation will deliver or cause to be
delivered at the Payment Office to or upon the written order of the holder of
such shares, certificates representing the number of full shares of Common
Stock issuable upon such conversion, issued in such name or names as such
holder may direct.  Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares in proper order for conversion, and all rights of the holder of such
share as a holder of such shares shall cease at such time and the person or
persons in whose name or names the certificates for such shares of Common Stock
are to be issued shall be treated for all purposes as having become the record
holder or holders thereof  at such time; provided, however, that any such
surrender and payment on any date when the stock transfer books of the
Corporation shall be closed shall constitute the person or persons in whose
name or names the certificates for such shares of Common Stock are to be issued
as the record holder or holders thereof for all purposes immediately prior to
the close of business on the next succeeding day on which such stock transfer
books are opened.

                          (ii)    The Corporation shall not be required to
issue fractional shares of Common Stock upon conversion of shares of Series C
Convertible Preferred Stock.  At the Corporation's discretion, in the event the
Corporation determines not to issue fractional shares, in lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the Conversion
Price.

                          (iii)   The issuance of certificates for shares of
Common Stock upon conversion shall be made without charge for any issue, stamp
or other similar tax in respect of such





                                     - 7 -
<PAGE>   9
issuance.  However, if  any such certificate is to be issued in a name other
than that of the holder of record of the shares converted, the person or
persons requesting the issuance thereof shall pay to the Corporation the amount
of any tax which may be payable in respect of any transfer involved in such
issuance or shall establish to the satisfaction of the Corporation that such
tax has been paid or is not payable.

                 (f)      Reservation of Stock Issuable Upon Conversion. The
Corporation shall reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series C Convertible Preferred Stock, 11,500,000 shares of
Common Stock.  If at any time the number of authorized and unissued shares of
Common Stock that are reserved for issuance upon conversion of the shares of
Series C Convertible Preferred Stock, shall not be sufficient to effect the
conversion of all then outstanding shares of the Series C Convertible Preferred
Stock, the Corporation will take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose,
including, without limitation, taking appropriate board action, recommending
such an increase to the holders of Common Stock, holding shareholders meetings,
soliciting votes and proxies in favor of such increase to obtain the requisite
stockholder approval and upon such approval, the Corporation shall reserve and
keep available such additional shares solely for the purpose of effecting the
conversion of the shares of the Series C Convertible Preferred Stock.

                 (g)      Notices.  Any notice required by the provisions of
this Certificate of Designation to be given to the holders of shares of Series
C Convertible Preferred Stock shall be deemed given five days after such notice
is deposited in the United States mail, postage prepaid, and addressed to each
holder of record at its address appearing on the books of the Corporation, or
the next business day after such notice is delivered to a recognized overnight
courier service with next-business day delivery specified.

                 (h)      Reorganization, Merger or Sale of the Corporation.

                           (i)    Notwithstanding any other provision hereof,
         in case of (A) any reorganization or any reclassification of the
         capital stock of the Corporation or (B) any merger or consolidation of
         the Corporation, that in any such case results in the Common Stock
         being converted into other securities or property, or the right to
         receive other securities or property, then, to the extent the
         Corporation or the holders do not otherwise redeem or convert all
         outstanding shares of Series C Convertible Preferred Stock,
         appropriate adjustment (as determined by the Board of Directors) shall
         be made in the application of the provisions herein set forth with
         respect to the rights and interests of the holders of the Series C
         Convertible Preferred Stock, to the end that the provisions set forth
         herein shall thereafter be applicable, as nearly as equivalent as is
         practicable, in relation to any shares of stock thereafter deliverable
         upon the conversion of the shares of Series C Convertible Preferred
         Stock.

                           (ii)   In case of any merger, consolidation,
         reclassification or other similar reorganization, to the extent the
         Corporation is not the surviving entity, and the Corporation





                                     - 8 -
<PAGE>   10
         or the holders do not otherwise redeem or convert all outstanding
         shares of Series C Convertible Preferred Stock, the Series C
         Convertible Preferred Stock shall be converted into or exchanged for
         and shall become shares of the surviving corporation having, in respect
         of the surviving corporation, substantially the same powers,
         preferences and relative participating, optional or other special
         rights, and the qualifications, limitations or restrictions thereon,
         that the Series C Convertible Preferred Stock had immediately prior to
         such transaction.  In the case the Corporation is not the surviving
         entity, the Conversion Price shall be adjusted at the closing of the
         transaction to equal the Conversion Price in effect immediately prior
         to the Closing divided by the fair market value of the Common Stock at
         the Closing multiplied by the fair market value of the Common Stock of
         the surviving entity at the Closing.

                          (iii)   References in this Section 5 to "Common
         Stock" shall include all stock or other securities or property
         (including cash) into which Common Stock is converted following any
         merger, reorganization or reclassification of the capital stock of the
         Corporation.

                 (i)      Adjustments.  The number of shares of Common Stock
issuable upon conversion of shares of the Series C Convertible Preferred Stock
that are then outstanding and the Conversion Price shall be subject to
adjustment from time to time as follows:

                          (i)     Stock Dividends; Stock Splits; Reverse Stock
         Splits.   In case the Corporation shall (A) declare or pay a dividend
         on its outstanding Common Stock in shares of Common Stock or make a
         distribution to all holders of its outstanding Common Stock in shares
         of Common Stock, (B) subdivide its outstanding Common Stock into a
         greater number of shares or reclassify its outstanding Common Stock,
         or (C) combine its outstanding Common Stock into a smaller number of
         shares, the number of shares of Common Stock issuable upon conversion
         of each share of Series C Convertible Preferred Stock shall be
         adjusted so that the holder of each such share shall thereafter be
         entitled to receive the kind and number of shares of Common Stock that
         such holder would have owned or have been entitled to receive after
         the happening of any of the events described above, had such share
         been converted in full immediately prior to the happening of such
         event or any record date with respect thereto (with any record date
         requirement being deemed to have been satisfied), and, in any such
         case, the number of shares of Common Stock issuable upon conversion of
         each such share shall be subject to further adjustments under this
         Section 5(i).  An adjustment made pursuant to this Section 5(i)(i)
         shall become effective at the record date, if any, for such event.

                          (ii)    Distributions to Stockholders.  In case the
         Corporation shall issue to  holders of its Common Stock rights,
         options, warrants or convertible or exchangeable securities
         (collectively, the "rights") entitling them to subscribe for or
         purchase Common Stock at a price per share of Common Stock (determined
         by dividing (A) the total amount receivable by the Corporation in
         consideration of the issuance of such rights plus the total
         consideration payable to the Corporation upon exercise, conversion or
         exchange thereof, by (B) the total number of shares of Common Stock
         covered by such rights) that is lower than





                                     - 9 -
<PAGE>   11
         the Current Market Price per share of Common Stock in effect 
         immediately prior to such issuance, then the number of shares of Common
         Stock issuable upon conversion of all shares of Series C Convertible
         Preferred Stock shall be increased in a manner determined by
         multiplying the number of shares of Common Stock theretofore issuable
         upon the conversion of all shares of Series C Convertible Preferred
         Stock by a fraction, the numerator of which shall be the number of
         shares of Common Stock outstanding immediately prior to the issuance of
         such rights plus the number of additional shares of Common Stock
         offered for subscription or purchase, and the denominator of which
         shall be the number of shares of Common Stock outstanding immediately
         prior to the issuance of such rights plus the number of shares of
         Common Stock which the aggregate consideration to be received by the
         Corporation in connection with such issuance (as defined in the
         following sentence) would purchase at the then Current Market Price per
         share of Common Stock.  For purposes of this Section 5(i), the "Current
         Market Price" per share of Common Stock for any date shall mean average
         of the closing prices of the Common Stock for the 10  trading days
         prior to such date. For purposes of this Section 5(i)(ii), the
         "aggregate consideration to be received by the Corporation" in
         connection with any issuance of such rights shall be deemed to be the
         consideration received by the Corporation for such rights plus any
         consideration or premiums stated in such rights to be paid for the
         shares of Common Stock covered thereby.
         
                          (iii)   Issuance of Common Stock at Lower Values.  In
         case the Corporation shall, in a transaction to which Section 5(i)(i)
         is inapplicable (and, in any event, other than upon conversion of
         Series A Preferred Stock, Series B Preferred Stock, or Series C
         Convertible  Preferred Stock, or upon exercise of any warrants or
         employee stock options that were outstanding on the Initial Issuance
         Date or pursuant to contractual commitments to which the Corporation
         was bound on the Initial Issuance Date), issue or sell shares of
         Common Stock, or rights, options, warrants or convertible or
         exchangeable securities containing the right to subscribe for or
         purchase shares of Common Stock, at a price per share of Common Stock
         (determined, in the case of rights, options, warrants or convertible
         or exchangeable securities, by dividing (A) the total amount
         receivable by the Corporation in consideration of the issuance and
         sale of such rights, options, warrants or convertible or exchangeable
         securities, plus the total consideration payable to the Corporation
         upon exercise, conversion or exchange thereof, by (B) the total number
         of shares of Common Stock covered by such rights, options, warrants or
         convertible or exchangeable securities) that is lower (at the date of
         such sale or issuance) than the Current Market Price per share of
         Common Stock in effect immediately prior to such sale or issuance or
         for no consideration, then in each case the number of shares of Common
         Stock thereafter issuable upon the conversion of the shares of Series
         C Convertible Preferred Stock shall be increased in a manner
         determined by multiplying the number of shares of Common Stock
         theretofore issuable upon the conversion of all shares of Series C
         Convertible Preferred Stock by a fraction, of which the numerator
         shall be the number of shares of Common Stock outstanding immediately
         prior to the sale or issuance, plus the number of additional shares of
         Common Stock offered for subscription or purchase or to be issued upon
         conversion or exchange of such convertible or exchangeable securities,
         and of which the denominator shall be the number of shares of Common
         Stock outstanding immediately prior to the sale or issuance plus the
         number of shares of Common Stock which the aggregate consideration to
         be





                                     - 10 -
<PAGE>   12
         received by the Corporation (as defined in the following paragraph) in
         connection with such sale or issuance would purchase at the then
         Current Market Price per share of Common Stock.

                 For the purpose of such adjustments the "aggregate
         consideration to be received by the Corporation" therefor shall be
         deemed to be the consideration received by the Corporation for such
         rights, options, warrants or convertible or exchangeable securities
         plus any consideration or premiums stated in such rights, options,
         warrants or convertible or exchangeable securities to be paid for the
         shares of Common Stock covered thereby.

                 In case the Corporation shall issue or sell shares of Common
         Stock or rights, options, warrants or convertible or exchangeable
         securities containing the right to subscribe for or purchase shares of
         Common Stock for a consideration consisting, in whole or in part, of
         property other than cash or its equivalent, then in determining the
         "price per share of Common Stock" and the "consideration" receivable
         by or payable to the Corporation for purposes of Sections 5(i)(ii) and
         5(i)(iii), the Board of Directors of the Corporation shall determine,
         in good faith, the fair value of such property.  In case the
         Corporation shall issue and sell rights, options, warrants or
         convertible or exchangeable securities containing the right to
         subscribe for or purchase shares of Common Stock, together with one or
         more other securities as part of a unit at a price per unit, then in
         determining the "price per share of Common Stock" and the
         "consideration" receivable by or payable to the Corporation for
         purposes of Sections 5(i)(ii) and 5(i)(iii), the Board of Directors of
         the Corporation shall determine, in good faith, the fair value of the
         rights, options, warrants or convertible or exchangeable securities
         then being sold as part of such unit.

                 Any increase of the number of shares of Common Stock issuable
         upon conversion of  shares of Series C Convertible Preferred Stock
         pursuant to this Section 5(i)(iii) shall be allocated among such
         Series C Convertible Preferred Stock on a pro rata basis.

                          (iv)    Expiration of Rights, Options and Conversion
         Privileges.  Upon the expiration of any rights, options, warrants or
         conversion or exchange rights that have previously resulted in an
         adjustment under this Section 5(i), if any thereof shall not have been
         exercised, the number of shares of Common Stock issuable upon
         conversion of Series C Convertible Preferred Stock shall be readjusted
         and shall thereafter, upon any future exercise, be such as they would
         have been had they been originally adjusted (or had the original
         adjustment not been required, as the case may be) as if (i) the only
         shares of Common Stock so issued were the shares of Common Stock, if
         any, actually issued or sold upon the exercise of such rights,
         options, warrants or conversion or exchange rights and (ii) such
         shares of Common Stock, if any, were issued or sold for the
         consideration actually received by the Corporation upon such exercise
         plus the consideration, if any, actually received by the Corporation
         for issuance, sale or grant of all such rights, options, warrants or
         conversion or exchange rights whether or not exercised; provided that
         no such readjustment shall have the effect of decreasing the number of
         shares issuable upon conversion of Series C Convertible Preferred
         Stock by a number that is in excess of the amount or number of the
         adjustment initially made in respect of the issuance, sale or grant





                                     - 11 -
<PAGE>   13
         of such rights, options, warrants or conversion or exchange rights or
         shall have the effect of decreasing the number of shares of Common
         Stock that have been issued upon conversion of any shares of Series C
         Convertible Stock prior to the date of such readjustment.

                          (v)     De minimis Adjustments.  No adjustment in the
         number of shares of Common Stock issuable under any Series C
         Convertible Preferred Stock shall be required unless such adjustment
         would require an increase or decrease of at least one percent (1%) in
         the number of shares of Common Stock purchasable upon a conversion of
         Series C Convertible Preferred Stock; provided, that any adjustments
         which by reason of this Section 5(i) are not required to be made shall
         be carried forward and taken into account in any subsequent
         adjustment.  All calculations shall be made to the nearest
         one-thousandth of a share.

                          (vi)     Notice of Adjustment.  Whenever the number
         of shares of Common Stock or other stock or property issuable upon the
         conversion of Series C Convertible Preferred Stock is adjusted, as
         herein provided, the Corporation shall deliver to the holders thereof
         a certificate of a firm of independent public accountants selected by
         the Board of Directors of the Corporation (who may be the regular
         accountants employed by the Corporation) setting forth the number of
         shares of Common Stock or other stock or property issuable upon the
         conversion of each share of Series C Convertible Preferred Stock after
         such adjustment, setting forth a brief statement of the facts
         requiring such adjustment and setting forth the computation by which
         such adjustment was made and shall promptly mail by first class mail,
         postage prepaid, to each holder notice of such adjustment or
         adjustments.

                          (vii)   Adjustment of Conversion Price.  Whenever the
         number of shares of Common Stock issuable upon conversion of the
         Series C Convertible Preferred Stock is adjusted as provided in this
         Section 5(i), the Conversion Price shall be adjusted by multiplying
         such Conversion Price immediately prior to such adjustment by a
         fraction, the numerator of which shall be the number of shares
         issuable upon conversion of a share of Series C Convertible Preferred
         Stock immediately prior to such adjustment, and the denominator of
         which is the number of shares so issuable immediately thereafter.


         6.      OPTIONAL REDEMPTION

                 (a)      Redemption Price.   Beginning on ____________, 2001
[third anniversary of closing], the Corporation, at its sole option, may redeem
all, but not less than all, shares of  the Series C Convertible Preferred Stock
for cash, at any time or from time to time, for  the  redemption price per
share set forth below:

</TABLE>
 .
                 For purposes hereof, "Redemption Value" for a share of Series
C Convertible Preferred Stock shall equal the greater of (i) Accreted Stated
Value, and (ii) if the Current Market Price of the Common Stock on the date of
the notice of redemption is greater than the Conversion Price, then an amount
determined in accordance with the following formula:

                                RV = (CMP)(SV)/CP

                         For purposes of this formula:

                                RV = Redemption Value per share
                                SV = Accreted Stated Value per share
                                CMP = Current Market Price
                                CP = Conversion Price

                 "Accreted Stated Value" per share means the Stated Value per
share plus accrued and unpaid dividends, if any, on such share through the date
of redemption.

                 (b)      Notice of Redemptions.  Notice of redemptions shall
be given by first class mail, postage prepaid, not less than 20 nor more than
60 business days prior to the redemption date or, if such notice period is not
feasible in connection with a transaction described in Section 5(g), such
notice period as is practicable in the circumstances, to each holder of record
of the shares to be redeemed, at such holder's address as the same appears on
the books of the Corporation.  Each such notice shall state: (i) the redemption
date; (ii) the place or places where certificates for such shares are to be
surrendered for payment of the redemption price; and (iii) that dividends on
the shares to be redeemed will cease to accrue on the redemption date.

                 (c)      Cessation of Dividends on Shares Redeemed.  Notice
having been mailed as stated in subsection (c) above, from and after the close
of business on the redemption date (unless default shall be made by the
Corporation in providing money for the payment of the redemption price of the
shares called for redemption), dividends on the shares of the Series C
Convertible Preferred Stock redeemed shall cease to accrue, and said shares
shall no longer be deemed to be outstanding, and all rights of the holders
thereof as stockholders of the Corporation (except the right to receive from
the Corporation the redemption price) shall cease.  Upon surrender in
accordance with said notice of the certificates for any shares so redeemed
(properly endorsed or assigned for transfer, if the Board of Directors of the
Corporation shall so require and the notice shall so state), such shares shall
be redeemed by the Corporation at the redemption price aforesaid.

<PAGE>   15
                 (d)      Status of Redeemed or Converted Shares.  Upon
redemption or conversion, any shares of the Series C Convertible Preferred
Stock which have been so redeemed or converted shall be retired and thereafter
have the status of authorized but unissued shares of preferred stock, without
designation as to series until such shares are once more designated as part of
a particular series by the Board of Directors or a duly authorized committee
thereof.


         7.      MANDATORY REDEMPTION.

         On ___________, 2010 [twelfth anniversary of closing] (the "Final
Redemption Date"), the Corporation shall redeem from any source of funds
legally available therefor, in the manner provided in Section 6(c) above, all
of the shares of the Series C Convertible Preferred Stock then outstanding at a
redemption price equal to the Stated Value per share, plus, without
duplication, an amount in cash equal to all accrued and unpaid dividends per
share to the Final Redemption Date.


         8.      PREEMPTIVE RIGHTS.

         No shares of Series C Convertible Preferred Stock shall have any
rights of preemption whatsoever as to any securities of the Corporation, or any
warrants, rights or options issued or granted with respect thereto, regardless
of how such securities or such warrants, rights or options may be designated,
issued or granted.


         9.      TRANSFERABILITY.

         No shares of Series C Convertible Preferred Stock shall be
transferable without the consent of the Corporation until _______________,
_____ [18 months after closing]; provided, however, this provision shall
terminate and be of no further force or effect immediately upon the occurrence
of a Problematic Regulatory Change of Control.  A "Problematic Regulatory
Change of Control" is a Change of Control which causes the Holder and/or its
affiliates to receive an attributable interest in any radio spectrum or FCC
Service with respect to which the FCC or applicable law imposes a spectrum cap
(including, without limitation, spectrum caps imposed on the holding of
broadband CMRS or narrowband PCS spectrum), multiple ownership restriction, or
other material limitation.  "FCC Service" shall mean any service subject to FCC
(or successor agency) regulation or oversight.

Stockholder's name in Annex A hereto as "Total Shares," such MC Stockholder
does not own, of record or beneficially, any MC Shares;
<PAGE>   2
                 (c)      this Agreement has been duly authorized by all
necessary action on the part of such MC Stockholder, has been duly executed by
such MC Stockholder and constitutes a valid and binding agreement of such
stockholder enforceable against such stockholder in accordance with its terms;
and

                 (d)      neither the execution and delivery of this Agreement
by such MC Stockholder nor the consummation of the transactions contemplated
hereby will (i) require any consent, approval, authorization or permit of, or
filing with or notification to, any governmental or regulatory authority or
other person or (ii) conflict with or result in any breach or violation of any
provision of any charter, by-law or agreement to which such MC Stockholder is a
party or by which it or he or she is bound.

         2.      Agreement to Vote or Consent.  Each MC Stockholder hereby
agrees to attend the meeting of stockholders of MC to be called pursuant to
Section 6.5 of the Stock Purchase Agreement (including any adjournment or
adjournments thereof) ("MC Meeting"), in person or by proxy, and to vote, or
cause to be voted (or, if the stockholders of MC act by written consent, to
consent in writing, or cause to consent in writing, with respect to) all MC
Shares, whether issued heretofore or hereafter, that such MC Stockholder owns
or has the right to vote or consent: (a) in favor of the issuance of the
Convertible Preferred Stock in the Transaction and (b) in favor of a proposed
amendment to the Amended and Restated Certificate of Incorporation of MC, as
amended, to increase the authorized number of MC Shares to 100,000,000.

         3.      Proxy.  To secure each MC Stockholder's commitments set forth
in Section 2, each MC Stockholder constitutes and appoints Wireless or its
officers, and each of them, with full power of substitution, to be its true and
lawful proxy and attorney-in-fact from the date hereof until conclusion of the
MC Meeting (including any adjournment or adjournments thereof) to vote all MC
Shares then beneficially owned by such MC Stockholder in accordance with
Section 2.  This proxy shall be deemed coupled with an interest, and is
irrevocable during the term of this Agreement and will survive the death,
incompetency and disability of any MC Stockholder who is an individual and will
survive the merger, liquidation, dissolution or other termination of any MC
Stockholder that is an entity.

         4.      Revocation of Proxies and Consents.  To the extent
inconsistent with Section 2 hereof, each MC Stockholder hereby revokes any and
all previous proxies or written consents with respect to such MC Stockholder's
Owned Shares.

         5.      Transfer.  From the date hereof until the first to occur of
the closing of the Transaction or the termination of the Stock Purchase
Agreement, no MC Stockholder will, directly or indirectly, sell, transfer,
pledge (other than pledges pursuant to commercially customary brokers margin
accounts) or otherwise dispose of, any Owned Shares (collectively, a
"Transfer") to any person other than Wireless or its designee, or grant an
option with respect to any of the foregoing, or enter into any other agreement
or arrangement with respect to any of the foregoing, unless such Owned Shares
remain  subject to the MC Stockholder's obligations hereunder in the hands of
any transferee, provided, that nothing in this Agreement shall preclude



                                       2
<PAGE>   3
the MC Stockholder from transferring that number of MC Shares in excess of the
number of Owned Shares free and clear of any obligations hereunder.

         6.      Specific Enforcement.  The parties hereto acknowledge that
damages would be an inadequate remedy for a breach of this Agreement and that
the obligations of the parties hereto shall be specifically enforceable, in
addition to any other remedy which may be available at law or in equity.

         7.      Termination.  This Agreement shall terminate on the earliest
of (i) the conclusion of the MC Meeting (including any adjournment thereof),
(ii) the agreement of the parties hereto to terminate this Agreement, or (iii)
termination of the Stock Purchase Agreement, but in any event shall terminate
no later than nine (9) months from the date of the Stock Purchase Agreement.

         8.      Successors and Assigns.  This Agreement shall not be assigned,
except by operation of law or otherwise without the prior written consent of
the other parties hereto.  This Agreement will be binding upon, inure to the
benefit of and be enforceable by each party and such party's respective heirs,
beneficiaries, executors, representatives and permitted assigns.

         9.      Scope of Agreement.  Nothing in this Agreement shall, is
intended to, or shall be construed to, limit or in any way restrict the ability
of any MC Stockholder to act in such MC Stockholder's capacity as an officer or
director of MC or to exercise or carry out such MC Stockholder's fiduciary
duties as an officer or director of MC, so long as such MC Stockholder fulfills
his obligations under this Agreement.

                                VOTING AGREEMENT

         VOTING AGREEMENT, dated as of  June 26, 1998 (this "Agreement"), by
and among AT&T Wireless Services, Inc., a Delaware corporation  ("Wireless"),

         WHEREAS, Metrocall, Inc. ("MC") and Wireless have entered into a Stock
Purchase Agreement of even date herewith (the "Stock Purchase Agreement"),
pursuant to which Wireless and certain of its affiliates have agreed to sell
their paging and messaging business and a 50KHz/50KHz Narrowband Personal

         WHEREAS, as of the date hereof, Stockholder is the beneficial owner

                 Stockholder represents and warrants to Wireless that:

                 (a)      the Stockholder is the beneficial owner of the

                 (c)      this Agreement has been duly authorized by all
necessary action on the part of the Stockholder, has been duly executed by the
Stockholder and constitutes a valid and binding agreement of such stockholder
enforceable against such stockholder in accordance with its terms; and

                 (d)      neither the execution and delivery of this Agreement
by the Stockholder nor the consummation of the transactions contemplated hereby
will (i) require any
<PAGE>   2
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority or other person (except for
filings required pursuant to the Securities Exchange Act of 1934) or (ii)
conflict with or result in any breach or violation of any provision of any
charter, by-law or agreement to which the Stockholder is a party or by which it

writing, or cause to consent in writing, with respect to) all MC Shares,
whether issued heretofore or hereafter, that the Stockholder owns or has the
right to vote or consent: (a) in favor of the issuance of the Convertible
Preferred Stock in the Transaction and (b) in favor of a proposed amendment to
the Amended and Restated Certificate of Incorporation of MC, as amended, to
increase the authorized number of MC Shares to 100,000,000.

         3.      Revocation of Proxies and Consents.  To the extent
inconsistent with Section 2 hereof, the Stockholder hereby revokes any and all
previous proxies or written consents with respect to the Stockholder's MC
Shares.

         4.      Transfer.  Nothing contained in this Agreement shall prevent
the Stockholder from selling, transferring, pledging or otherwise disposing of,
any MC Shares.  Notwithstanding anything to the contrary contained in this
Agreement, the parties hereto understand that the MC Shares have been pledged
by the Stockholder to secure obligations under its Credit Agreement and the
Stockholder's obligations hereunder are subject to continued compliance by the
Stockholder with its obligations under such Credit Agreement and the Security
Agreement related thereto.  The Stockholder represents that it presently is in
compliance with its obligations under the Credit Agreement and Security
Agreement.

         5.      Specific Enforcement.  The parties hereto acknowledge that
damages would be an inadequate remedy for a breach of this Agreement and that
the obligations of the parties hereto shall be specifically enforceable, in
addition to any other remedy which may be available at law or in equity.

         6.      Termination.  This Agreement shall terminate on the earliest
of (i) the conclusion of the MC Meeting (including any adjournment thereof),
(ii) the agreement of the parties hereto to terminate this Agreement, or (iii)
termination of the Stock Purchase Agreement, but in any event shall terminate
no later than nine (9) months from the date of the Stock Purchase Agreement.
In addition, this Agreement shall terminate with respect to MC Shares when they
are no longer beneficially owned by the Stockholder.

         7.      Successors and Assigns.  This Agreement shall not be assigned,
except by operation of law or otherwise without the prior written consent of
the other parties hereto.  This Agreement will be binding upon, inure to the
benefit of and be enforceable by each party and such party's respective heirs,
beneficiaries, executors, representatives and permitted assigns.
