                              EMPLOYMENT AGREEMENT

         This Agreement is made as of the fourth day of August, 1997 (the
"Effective Date"), between Paging Network, Inc., a Delaware corporation
("PageNet"), and John P. Frazee, Jr., of Tallahassee, Florida (the "Executive").

                              W I T N E S S E T H:

         WHEREAS, PageNet and the Executive desire to enter into an employment
relationship upon the terms and conditions hereinafter set forth; and

         WHEREAS, the Executive will be employed in a capacity in which he may
receive and contribute to confidential information, as to which PageNet desires
fully to protect its rights;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements herein set forth, the parties hereto agree as follows:

         1.      Employment. The Executive hereby agrees to serve as a
corporate officer with the title of Chairman, President and Chief Executive
Officer of PageNet, for the term of this Agreement, subject to the terms set
forth herein and the provisions of the Bylaws of PageNet. During his employment
in such position, Executive shall report directly to the Board of Directors of
PageNet (the "PageNet Board"). During his employment hereunder, the Executive
shall devote his efforts and attention, substantially on a full-time basis, to
the performance of the duties required of him as an executive of PageNet. It is
agreed and understood that the Executive may continue to serve as a director
(or similar position) of those entities for which the Executive presently
serves, and the Executive may serve in such capacities for other entities
provided such service does not materially interfere with the Executive's duties
and responsibilities hereunder.

         2.      Compensation. As compensation for his services during the term
of this Agreement, the Executive shall receive the amounts and benefits set
forth in subsections (a), (b), (c), (d), (e) and (f) below:

                 (a)      A base salary effective as of the Effective Date of
         six hundred fifty thousand dollars ($650,000) per year (the "Base
         Salary"), prorated for any partial year of employment, subject to
         annual review for increases in the sole discretion of the PageNet
         Board after recommendation of the Compensation Committee of the
         PageNet Board (the "Compensation Committee"), in light of the
         performance of PageNet and the Executive. The Executive's salary shall
         be payable semi-monthly, or in accordance with
<PAGE>   2


                                     -2-



         PageNet's regular payroll practices in effect from time to time for
         senior executives of PageNet.

                 (b)      Annual incentive compensation during the term of
         this Agreement with a target of three hundred fifty thousand dollars
         ($350,000), such incentive compensation hereinafter referred to as
         the "Incentive Bonus". The Incentive Bonus shall be determined by the
         executive incentive bonus plan, which shall be approved by the PageNet
         Board (after recommendation of the Compensation Committee) in its sole
         discretion based upon the achievement by PageNet of its overall
         corporate objectives for such year. The level of the Incentive Bonus
         will depend upon the PageNet Board's determination of the degree to
         which the objectives have been met. The objectives, the executive
         incentive bonus plan and levels of performance on which the Incentive
         Bonus will be determined may be changed from time to time by the
         PageNet Board (after recommendation of the Compensation Committee).
         The Incentive Bonus shall be payable to the Executive in full only if
         the Executive is actively employed on the February 1 following the
         calendar year for which the Incentive Bonus is being paid, and
         otherwise the Executive shall be considered for a bonus on a pro rata
         basis in the discretion of the PageNet Board for any partial calendar
         year of employment (so long as the Executive has not been terminated
         for "Good Cause," as defined in Section 12 below) and shall be paid in
         total no later than the later of: (i) February 1 of the year following
         the calendar year for which the Incentive Bonus is being paid, or (ii)
         fifteen (15) business days following the determination of the amount
         of the Incentive Bonus for the calendar year for which the Incentive
         Bonus is to be paid. The Incentive Bonus shall be payable as follows:
         (i) no less than forty percent (40%) of the amount of the Incentive
         Bonus shall be paid through the original issuance to the Executive of
         that number of shares of Paging Network, Inc. Common Stock, $.01 par
         value per share (the "Common Stock"), having a value (calculated based
         on the market value of the Common Stock on such date as the bonus is
         determined) equal to the portion of the Incentive Bonus to be paid in
         Common Stock, provided, that the Executive, in his sole discretion,
         may elect to increase the percentage of the Incentive Bonus payable in
         Common Stock up to a maximum of one hundred percent (100%), and (ii)
         the remainder of the Incentive Bonus shall be paid in cash. Any Common
         Stock issued to the Executive pursuant to the provisions of this
         Section 2(b) shall have been registered under the Securities Act of
         1933, as amended (the "Securities Act").

                 (c)      Participation by the Executive in, in accordance with
         the terms of, any employee benefit plans maintained from time to time
         by PageNet for the purpose of providing retirement, deferred
         compensation, health care, life insurance, disability and similar
         benefits to senior executives of PageNet.

                 (d)      The original issuance to the Executive of 11,510
         shares of Common Stock pursuant to the Paging Network, Inc.1997 
         Restricted Stock Plan, which shares have been registered under the 
         Securities Act.

                 (e)      Participation by the Executive in, in accordance with
         the terms of and at the discretion of the PageNet Board (after
         recommendation of the Compensation Committee), any employee stock
         purchase plan, stock option plan or other incentive plans made
         generally available to senior executives of PageNet. Initially, and as
         an inducement essential to the Executive's entering into this
         Agreement, the Executive shall be granted a stock option for 600,000
         shares of Common Stock, such option to be granted at an exercise price
         of $8.688, being the fair market value of a share of Common Stock on
         the Effective Date. Such option shall be granted, to the extent of
         500,000 shares, under the 1991 Stock Option Plan (which shares have
         been registered under the Securities Act) and, to the extent of
         100,000 shares, in an option not issued under any plan and the shares
         of which the Company shall promptly register on Form S-8 under the
         Securities Act. Such option shall vest and become exercisable as
         follows: (i) 200,000 shares shall vest on the Effective Date, and (ii)
         the remaining shares shall vest in equal installments on each of the
         first and second anniversaries of the Effective Date so long as the
         Executive's employment continues on such anniversary dates, with all
         such shares being vested in the event of a Change in Control (as
         hereinafter defined), provided, that any such accelerated vesting upon
         a Change in Control shall be subject to the Executive's agreement to
         remain as President and Chief Executive Officer for a reasonable
         period of time (not to exceed three (3) months) after such Change in
         Control in order to facilitate any transition occasioned by such
         Change in Control.

                 (f)      Reimbursement of ordinary and necessary travel and
         other expenses (other than those provided in Section 3 below), subject
         to PageNet's standard policies (including required documentation and
         approvals).

         3.      Relocation and Commuting. PageNet will provide the Executive
with the following during the term of this Agreement and the Executive's
employment hereunder:

                 (a)      PageNet will provide a furnished apartment in the
         Dallas, Texas metropolitan area for the exclusive use of the Executive
         and his family (up to a maximum of $3,000 per month), provided that
         the cost of providing such furnished apartment shall be payable to the
         Executive if and when he purchases a residence in the Dallas, Texas
         metropolitan area.

                 (b)      PageNet shall provide the Executive with private jet
         transportation, through a time-sharing arrangement, to and from the
<PAGE>   4
                                      -4-



         Executive's primary residence in Florida and to and from Dallas, Texas
         or wherever the Executive is conducting PageNet business.

         4.      Term.

                 (a)      This Agreement and the Executive's employment
         hereunder shall be effective as of the Effective Date, and shall
         continue until July 31, 1998. This Agreement shall be automatically
         renewed for successive one-year periods at the end of the initial
         term, unless either party gives notice to the other of its intent to
         terminate this Agreement not less than 90 days prior to the
         commencement of any such one-year renewal period.  In the event such
         notice to terminate is properly given, this Agreement shall terminate
         at the end of the initial term or the one-year renewal period during
         which the notice is given, as the case may be.

                 (b)      The Executive's employment hereunder may be
         terminated by either party prior to the end of the term hereof
         (including any renewal period) upon written notice to the other
         party, provided that, in the event of such termination, PageNet shall
         be obligated to make the payments and provide the benefits, if any,
         described in Section 5 below. In the event of any termination, the
         Executive agrees to resign any offices he holds on such date as an
         officer or director of PageNet or any of its subsidiaries and other
         affiliates.

         5.      Termination Payments. Upon termination of the Executive's
employment prior to the end of the term of this Agreement (including any
renewal term), PageNet shall pay to the Executive in cash any amount payable
pursuant to (a) and (b) below, and shall for the period or at the time
specified provide the other benefits described in (c), if any, below:

                 (a)      If: (i) the Executive's employment is terminated by
         PageNet other than for "Good Cause," as defined in Section 12 below,
         (ii) the Executive's employment is terminated by reason of the
         Executive's death or "Disability," as defined in Section 12 below; or
         (iii) the Executive elects to terminate his employment for "Good
         Reason," as defined in Section 12 below, then the Executive shall be
         paid his Base Salary through the end of the initial term or the
         one-year renewal period, as the case may be, during which his
         employment is terminated, and his pro rata bonus for such calendar
         year during which his employment is terminated.

                 (b)      If the Executive's termination of employment is not
         described in (a) above, the Executive shall be paid any unpaid Base
         Salary through the date of termination.

                 (c)      If the Executive's termination of employment is
         described in (a) above, any health care and life insurance benefits
         coverage provided to the
<PAGE>   5
                                      -5-



         Executive at his date of termination shall be continued at the same
         level and in the same manner through the initial term or the relevant
         one-year renewal period, as the case may be, during which his
         employment is terminated and any additional coverages the Executive
         had at termination, including dependent coverage, will also be
         continued for such period on the same terms. Any costs the Executive
         was paying for such coverages at the time of termination shall
         continue to be paid by the Executive. If the terms of any benefit plan
         referred to in this section do not permit continued participation by
         the Executive, as provided in this subsection, then PageNet will
         arrange for other coverage providing substantially similar benefits.

        6.      Nondisclosure: Confidentiality. The Executive agrees that
during the term of his employment and for a period of two (2) years after
termination, he shall not, directly or indirectly, disclose or give to others
any confidential fact or information not available to the public concerning
PageNet's financial operations and businesses.  Such confidential business
information includes any non-public business plans, financial information,
financial systems, financing arrangements, and any other secret or confidential
work, knowledge, know-how, trade secret or confidential business information,
confidential information relating to customer accounts, customer needs, product
mix, organization, strategy, research and development, discoveries, software in
various stages of development, design, drawings, specifications, techniques,
processes, procedures, "know-how," marketing techniques and materials, marketing
and development plans, price lists, pricing policies and other confidential
information relating to customers.
        
         7.      Non-Solicitation. The Executive agrees that during the term of
his employment and for a period of one (1) year after termination, he shall
not, directly or indirectly, for himself or on behalf of another, hire any
employee, or solicit or induce any employee to leave his or her employment with
PageNet or any of its subsidiaries or affiliates.

         8. Tax Gross-Up.

                 (a)      In the event that any of the benefits provided for in
         Section 3 hereof will be subject to income tax imposed by the Internal
         Revenue Code of 1986, as amended (the "Code") and any applicable state
         and local income tax law (collectively, the "Tax"), the Corporation
         shall immediately pay to or to the order of the Executive an
         additional amount (the "Gross-up Payment") such that the net amount
         retained by the Executive, after deduction of any Tax on such benefits
         and any federal, state and local income tax on the payment provided
         for by this Section 8(a), shall be equal to the amount of such
         benefits, placing the Executive in the same after-tax financial
         position in which he would have been if he had not incurred any such
         income tax liability for the benefits provided under Section 3 hereof.
         For purposes of determining
<PAGE>   6
                                      -6-



         the amount of the Gross-up Payment, the Executive shall be deemed to
         pay federal income taxes at the highest marginal individual rate of
         federal income taxation on compensation in the calendar year in which
         the Gross-up Payment is to be made and state and local income taxes at
         the highest marginal individual rate of taxation on compensation in
         the state and locality of the Executive's residence on the last day of
         the calendar year for which the gross-up payment is to be made, net of
         the maximum reduction in federal income taxes which could be obtained
         from deduction of such state and local taxes.

                 (b)      In the event that the Tax is subsequently determined
         to be less than the amount taken into account hereunder at the time of
         determination, the Executive shall repay to the Corporation at the
         time that the amount of such reduction in Tax is finally determined
         the portion of the Gross-up Payment attributable to such reduction
         (plus the portion of the Gross-up Payment attributable to the Tax and
         federal, state and local income tax imposed on the Gross-up Payment
         being repaid by the Executive, if such repayment results in a
         reduction in Tax or in federal, state and local income tax deductions)
         plus interest on the amount of such repayment at the rate provided in
         Section 1274(d) of the Code.

         9.      Damages and Injunctive Relief. The Executive agrees that the
breach of any of his obligations under Sections 6 or 7 of this Agreement (a)
may cause injury to PageNet and that PageNet is entitled to seek and obtain
compensation and damages, and (b) may cause irreparable injury to PageNet and
that, accordingly, PageNet may seek and obtain injunctive relief against the
breach or threatened breach of those provisions, in addition to other remedies
at law or in equity which may be available.

         10.     Assignment:  Successors.

                 (a)      The rights and benefits of the Executive under this
         Agreement, other than accrued and unpaid amounts due hereunder, are
         personal to him and shall not be assignable, except with the prior
         written consent of PageNet.

                 (b)      This Agreement shall not be assignable by PageNet,
         provided, that with the consent of the Executive, PageNet may assign
         this Agreement to (i) another corporation wholly-owned by it, either
         directly or through one or more other corporations, or (ii) any
         corporate successor of PageNet or any such corporation.

                 (c)      Notwithstanding the foregoing, any business entity
         succeeding to substantially all of the business of PageNet by
         purchase, merger, consolidation, sale of assets or otherwise, shall be
         required as a condition to the closing of such transaction to agree to
         be bound by and shall adopt and assume this Agreement.
