      Section 4. Compensation.

      (a) Reimbursement. The Company shall reimburse Manager for all

providing services under this Agreement). Manager shall provide the Company with
a statement setting forth in reasonable detail (and with copies of invoices or

responsibilities with respect to the Business, the Company shall pay Manager,
commencing on the date hereof, a management fee per annum equal to $550,000,
payable monthly in arrears on the last day of each calendar month. The
Compensation Committee of the Board of Directors shall annually review the
management fee in light of the performance of Manager and the Company, and may,
in its discretion, increase (but not decrease) the management fee by an amount
it determines to be appropriate. Manager's annual management fee payable
hereunder, as it may be increased from time to time, is referred to herein as
the "Management Fee." For

<PAGE>

each calendar year or part thereof during the term of this Agreement, Manager
shall be eligible to receive an annual bonus based upon the achievement of
certain objectives determined by the Compensation Committee of the Board of
Directors for such calendar year (the "Annual Bonus") payable within 30 days
after the certification of the Company's financial statements for such year but
in no event shall such bonus be less than 50% of the preceding year's Management
Fee.

      (c) Disputes, etc. If the Company disputes the amount of expenses or fees
claimed by Manager, the Company shall notify Manager in writing before payment

either the Company or Manager may request resolution of the dispute pursuant to
Section 10. The Company shall pay when due the portion of any such amounts that
is not in dispute.

      (d) Directors and Officers Liability Insurance. The Company shall use its
reasonable efforts to obtain and maintain directors and officers liability
insurance coverage in amounts customary for similarly situated companies in the
telecommunications industry.

      (e) Benefits. During the Term of this Agreement, Vento and Sullivan shall
be entitled to participate in any welfare benefit plan sponsored or maintained
by the Company to the extent Vento or Sullivan, as applicable, is eligible to

      part of its property, or constituting an order for relief or approving a
      petition in bankruptcy or insolvency law of any jurisdiction, or ordering
      the dissolution, winding-up or liquidation of such party; or if a party

      thereafter; or an order shall have been issued granting such party a
      suspension of payments under applicable law and any such order is not

            (iii) Notwithstanding any provision herein to the contrary, upon the

      (and shall not be subject to repurchase by the Company) on the date of
      such termination.

            (iv) The Company shall be entitled to set off against the Management
      Fee payable to the Manager following the termination of this Agreement
      pursuant to Section 5(c)(ii), any amounts earned by either Vento or
      Sullivan in other employment after the termination of this Agreement
      during the period in which the Company is paying the Manager the

      this Agreement pursuant to Sections 5(b)(ii)(B), (C) or (D) or Sections
      5(b)(iii)(A), (B) or (C); provided, however, that neither Vento nor
      Sullivan shall be required, as a condition to the receipt of such payment
      pursuant to Section 5(c)(ii), to seek such other employment.

      (d) Remedies. The remedies set forth herein are not intended to be
exclusive, and all remedies shall be cumulative and may be exercised

in equity.

      (e) Continuing Obligations. After receipt of written notice of
termination, but prior to the effective date of such termination, Manager shall
continue to perform under this


                                       9
<PAGE>

Agreement unless specifically instructed to discontinue such performance. In the
event of termination, Manager and the Company shall remain liable for their
respective obligations accrued under this Agreement prior to the effective date
of termination.

      (f) Transition Arrangements.

            (i) In the event of termination of this Agreement for any reason,
      Manager shall at the Company's expense cooperate with the Company in order
      to facilitate the transition to a new management service provider (the
      "New Provider"). Upon such termination, the Board of Directors (excluding
      Vento and Sullivan) shall nominate a New Provider that would not cause a
      significant detrimental effect on the eligibility of the Company to
      realize the benefits, if any, that the Company derives from its status as
      a "very small business," as defined in 47 CFR Section 24.720(b)(2), which
      New Provider shall be acceptable to the Manager. In the event that the
      Manager does not approve such New Provider within five (5) business days
      of notice of such nomination by the Board of Directors, then for each
      successive thirty (30) day period or portion thereof following such five
      (5) business day period that a New Provider shall not have been approved
      by Vento and Sullivan, each of Vento and Sullivan shall sell to the
      Company, 50% of the Shares, inclusive of those Shares already subject to
      repurchase pursuant to Section 7(b), then owned by each of them at a price
      per share equal to $.0l per Share. Manager shall at the Company's expense
      take whatever steps are commercially reasonable to assist the New Provider
      in assuming the management of the Company and the operation of the
      Business including, without limitation, transferring to the New Provider
      all historical financial, tax, accounting and other data in the possession
      of Manager, and giving such consents, assigning such permits and executing
      such instruments as may be necessary to vest in the New Provider those
      rights that were necessary for Manager to perform its services hereunder.

            (ii) Within five (5) business days after the nomination by the Board
      of Directors of a New Provider, each of Vento and Sullivan agrees to
      nominate a successor Person or group of Persons (collectively, a
      "Successor Control Group") that would not cause a significant detrimental
      effect on the eligibility of the Company to hold a Block F PCS license and
      to realize the benefits, if any, that the Company derives from its status
      as a "very small business," as defined in 47 CFR Section 24.720(b)(2), to
      whom the Voting Preference Common Stock, the Class C Common Stock set
      forth on Schedule I (the "Class C Common Stock") and any shares of Class E
      Common Stock acquired by Vento and Sullivan after the date hereof as
      contemplated by Section 7(f) below (any such shares being referred to as
      the "Class E Common Stock") shall be transferred by Vento and Sullivan,
      which Successor Control Group shall be reasonably acceptable to the Board
      of Directors in its sole discretion (excluding Vento and Sullivan); it
      being understood that the New Provider shall be deemed to be a Successor
      Control Group reasonably acceptable to the Board of Directors. In the
      event that Vento and Sullivan do not nominate a Successor Control Group
      reasonably acceptable to the Board of Directors in its sole discretion
      (excluding Vento and Sullivan) within such five (5) business day period,
      then for each successive 30-day period or portion thereof that Vento and
      Sullivan shall not have nominated a successor Control Group reasonably
      acceptable to the Board of Directors in its sole discretion (excluding
      Vento and Sullivan), each of Vento and


                                       10
<PAGE>

      Sullivan shall sell to the Company after the expiration of each 30-day
      period, in addition to any other Shares repurchased, and after giving
      effect to the repurchase by the Company of Shares pursuant to Section
      5(f)(i), an additional 50% of the Shares then owned by each of them at a
      price per share equal to $.01 per share. Immediately after a Successor
      Control Group reasonably acceptable to the Board of Directors is
      nominated, the Company, Vento and Sullivan shall take, or cause to be
      taken, all actions necessary or required, including, without limitation,
      filing of all applications with the FCC, to obtain all requisite consents
      and authorizations to permit the transfer of the Voting Preference Common
      Stock, Class C Common Stock and Class E Common Stock to the Successor
      Control Group. On the first business day after all such consents and
      authorizations shall have been obtained, Vento and Sullivan agree to
      resign as directors and officers of the Company and to sell to the
      Successor Control Group all of the shares of Voting Preference Common
      Stock, Class C Common Stock and Class E Common Stock owned by them for a
      per share price equal to the fair market value of the Company's Class A
      Common Stock. If at any time, whether by reason of the inability of the
      Company to obtain all requisite consents and authorizations to permit the
      transfer of the Voting Preference Common Stock, Class C Common Stock and
      Class E Common Stock to the Successor Control Group or otherwise, the
      Board of Directors withdraws its consent to the nomination of a Successor
      Control Group, the procedure outlined in Sections 5(f)(i) and (ii) shall
      be repeated commencing with the nomination by Vento and Sullivan of a
      Successor Control Group within five (5) business days after the nomination
      by the Board of Directors of a successor New Provider.

      (g) Return of Information. Upon termination of this Agreement, all books
and records in the possession of Manager relating to the maintenance and
operation of and accounting for the Company, together with all supplies and
other items of property owned by the Company and in Manager's possession, shall
be delivered to the Company.

      Section 6. Noncompetition and Confidentiality.

      (a) Noncompetition. During the Term and (x) for one year thereafter if
after the expiration of the Term the Company offers to extend this Agreement for
at least one (1) year on terms and conditions no less favorable than those
contained herein and the Manager rejects such offer, and (y) for so long as the
Company is paying to the Manager the Management Fee pursuant to Section 5(c)(ii)
following the termination of this Agreement pursuant to Sections 5(b)(ii)(B),
(C) or (D) or Sections 5(b)(iii) (A), (B) or (C), none of Manager, Vento,
Sullivan or any of their respective Affiliates shall, without the consent of the
Company, assist or become associated with any person or entity, whether as a
principal, partner, employee, consultant or shareholder (other than as a holder
of not in excess of 5% of the outstanding voting shares of any publicly traded
company) that is actively engaged in the business of providing mobile wireless
telecommunications services in the Territory.

      (b) Confidentiality. Without the prior written consent of the Company,
except to the extent required by an order of a court having competent
jurisdiction or under subpoena from a governmental body or agency, none of
Manager, Vento, Sullivan or any of their respective Affiliates shall disclose
any trade secrets, customer lists, drawings, designs, information regarding
product development, marketing plans, sales plans, manufacturing plans,
financial


                                       11
<PAGE>

records, packaging design or other financial, commercial, business or
technical information relating to the Company or any of its subsidiaries or
affiliates (collectively, "Confidential Information"), to any third person,
unless such Confidential Information has been previously disclosed to the public
by the Company or is in the public domain (other than by reason of Manager's,
Vento's, Sullivan's or any of their respective Affiliates' breach of this
Section 6(b)), except that Manager, Vento, Sullivan and their respective
Affiliates may disclose Confidential Information to the extent advisable in
their sole discretion in connection with (i) the performance of Manager's duties
hereunder, or (ii) the issuance of Company securities, or (iii) obtaining
financing for the Company, or (iv) the enforcement of Manager's rights under
this Agreement, or (v) any disclosures that may be required by law, including
securities laws.

      (c) Company Property. Promptly following the termination of this
Agreement, Manager, Vento and Sullivan shall return to the Company all property
of the Company, and all copies thereof in its possession or under its control,
and all tangible embodiments of Confidential Information in its possession in
whatever media such Confidential Information is maintained.

      (d) Non-Solicitation of Employees. During the Term and for one year
thereafter, none of Manager, Vento, Sullivan or any of their respective
Affiliates will directly or indirectly induce any employee of the Company or any
of its subsidiaries or affiliates to terminate employment with such entity, and
will not directly or indirectly, either individually or as owner, agent,
employee, consultant or otherwise, employ or offer employment to any person who
is or was employed by the Company or a subsidiary thereof, unless such person
shall have ceased to be employed by such entity for a period of at least six
months.

      (e) Injunctive Relief with Respect to Covenants. Manager, Vento and
Sullivan acknowledge and agree that the covenants and obligations with respect
to noncompetition, inventions, confidentiality and Company property contained in
this Section 6 relate to special, unique and extraordinary matters and that a
violation of any of the terms of such covenants and obligations will cause the
Company irreparable injury for which adequate remedies are not available at law.
Therefore, Manager, Vento and Sullivan agree that the Company shall be entitled
to an injunction, restraining order, or such other equitable relief as a court
of competent jurisdiction may deem necessary or appropriate to restrain Manager,
Vento and Sullivan from committing any violation of the covenants and
obligations contained in this Section 6. These injunctive remedies are
cumulative and are in addition to any other rights and remedies the Company may
have at law or in equity. Notwithstanding the foregoing, in the event that this
Agreement is terminated by the Company pursuant to Section 5(b)(ii)(A) by reason
of the indictment or conviction of Vento, Sullivan or the Manager of any felony
or any act constituting fraud, misappropriation or embezzlement due to the
wrongful acts of either Vento or Sullivan, that materially adversely effects the
Company or the Business monetarily or otherwise (as determined by a majority
vote of the Board of Directors (excluding Vento and Sullivan), Sullivan or
Vento, as applicable, shall sell to the Company, and the Company shall purchase
from Vento or Sullivan, as applicable, all of the Shares (whether or not vested)
at a price per share equal to $.0l per Share, it being understood that in the
event that the Company shall have terminated this Agreement by reason of any
such event, and either Vento or Sullivan shall not have been indicted for or
been convicted of any felony or act constituting fraud, misappropriation or
embezzlement that materially adversely effects the Company or the Business
monetarily or otherwise (as determined by a majority vote of the Board of
Directors (excluding


                                       12
<PAGE>

Shares to the Company.

      Section 7. Vesting and Repurchase of Restricted Shares, Etc.; Company Loan

directors or shareholders of the Company or other persons or organizations to

hereby directed to permit transfer of such Shares only in accordance with this
Agreement and the Stockholders Agreement. In the event further instructions are
desired by the Escrow Holder, he shall be entitled to rely upon written
directions of the Board of Directors (excluding Vento and Sullivan). The Escrow
Holder shall have no liability for any act or omission hereunder while acting in
good faith in the exercise of his own judgment. If the Company or any assignee
repurchases any of such Shares pursuant to this Section 7, the Escrow Holder,
upon receipt of written notice of such repurchase from the proposed transferee,
shall take all steps necessary to accomplish such repurchase. From time to time,
upon a Restricted Holder's request, the Escrow Holder shall: (i) cancel the
certificate(s)


                                       13
<PAGE>

held by the Escrow Holder and representing such Shares, (ii) cause new
certificate(s) to be issued representing the number of Shares no longer subject
to repurchase pursuant to this Section 7, which certificate(s) the Escrow Holder
shall deliver to such Restricted Holder, and (iii) cause new certificate(s) to
be issued representing the balance of such Shares, which certificate(s) shall be
held in escrow by the Escrow Holder in accordance with the provisions of this
Section 7(d). Subject to the terms hereof, a Restricted Holder shall have all
the rights of stockholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote such Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's repurchase right, there is (i) any stock dividend, stock split or
other change in such Shares, or (ii) any merger or sale of all or substantially

theretofore vested pursuant to Schedule II shall be endorsed with the following
legend (in addition to any legend required to be placed thereon by applicable
federal or state securities laws or the Stockholders Agreement):

            IN ACCORDANCE WITH THE TERMS OF A MANAGEMENT AGREEMENT BETWEEN THE
            COMPANY AND AN AFFILIATE OF THE STOCKHOLDER, A COPY OF WHICH IS ON
            FILE WITH THE SECRETARY OF THE COMPANY, WHICH PROVIDES, AMONG OTHER
            THINGS FOR THE REPURCHASE BY THE COMPANY OF THE SHARES REPRESENTED
            BY THIS CERTIFICATE.

      (f) Company Loans. In the event that Vento and Sullivan are permitted to
purchase shares of the Company's capital stock owned by William Mounger and/or
E.B. Martin pursuant to the employment agreements by and between the Company and
such Persons, then upon the request of Vento and/or Sullivan, the Company shall
lend Vento and Sullivan such amounts as needed in order to fund such purchases,
upon such terms as the parties may agree to, which terms shall include that any
such loan shall be non-recourse to the borrower, and Schedule I hereto shall be
amended to reflect such purchase. Such shares shall be subject to purchase by
the Company if this Agreement is terminated for any reason at a price per share

Agreement, Manager shall not be liable for any failure or delay in its
performance hereunder (except with respect to its performance of its obligations

such failure, delay or substandard performance is the result of willful
misconduct or gross negligence on the part of Manager.

      (c) No Consequential or Special Damages. Manager shall not be responsible
to the Company for any indirect, incidental, consequential or special damages to
the Company, the Business or any subscriber or customer of any Business or any
other person, including any damage to or loss of revenues, business or goodwill,

and control of the Business. The Company shall have control over and access, at
all reasonable times during normal business hours, to the books and records
maintained by Manager pursuant to this Section 9.

      Section 10. Dispute Resolution.

      (a) Dispute Resolution. The parties desire to resolve disputes arising out
of this Agreement without litigation. Accordingly, except for an action seeking
a temporary restraining order injunction related to the purposes of this
Agreement, or suit to compel compliance with this dispute resolution process,
the parties agree to use the dispute resolution procedures set forth in Section
10 as their sole remedy with respect to any controversy or claim arising out of
or relating to this Agreement or its breach.

      At the written request of any party, the parties to the dispute will

first mediation session shall take place no later than ten (10) days after the
initial written request to negotiate. The mediation shall continue until the
dispute is resolved or until such time as the mediator makes a good faith
determination that the likelihood of resolution is sufficiently remote that
continuation of the mediation is not warranted.

      (c) Arbitration. If the mediation conducted pursuant to Section 10(b) does
not resolve the dispute within thirty (30) days of the commencement of
mediation, or if prior to the expiration of such thirty (30) day period the
mediator determines that continuation of the mediation process is not warranted,
the dispute shall be submitted to binding arbitration by a panel of three
arbitrators pursuant to the Commercial Arbitration Rules of the American
Arbitration Association. Any party may demand such arbitration in accordance
with the procedures set out in those rules. Each party shall have the right to
take the deposition of up to five individuals (or a larger number of individuals
with the consent of two of the three arbitrators), and any expert witness
designated by the other party. Each party shall also have the right to request
production of relevant documents, the scope and enforcement of which shall be
governed by the arbitrator. Additional discovery may be only by order of the
arbitrator, and only upon a showing of substantial need. The arbitrator shall be
authorized to issue subpoenas for the purpose of requiring attendance of
witnesses at depositions. The arbitration hearing shall be commenced within ten
(10) days of the determination that mediation is not going to be successful. The
arbitration shall be held in New York, New York or such other location as
mutually agreed upon by the parties. The arbitrator shall control the scheduling
so as to process the matter expeditiously. The parties may submit written
briefs. The arbitrator shall rule on the dispute by issuing a written opinion
within thirty (30) days after the close of hearings. The times specified in this
section may be extended upon mutual agreement of the parties or by the
arbitrator upon a showing of good cause. The award rendered by arbitration shall
be a final, binding and nonappealable judgment and the award may be entered in
any court of competent jurisdiction in the United States. Special, consequential
or punitive damages shall not be awarded by the arbitrator.

disclosed only to employees and agents of the parties who shall have a "need to
know" the information and who shall have been made aware of the confidentiality
obligations set forth in this Section, unless the party is required by law to
disclose such information.

      (e) Fees and Expenses. The parties shall equally split the fees of the
mediator and the arbitrator. Any party found by the arbitrator to have breached
this Agreement shall pay all other out-of-pocket costs and expenses, including
reasonable attorneys' fees and expenses, of the other party incurred in
connection with the dispute resolution process. If the arbitrator does not find
that any party has breached this Agreement, then each party shall bear its own

      (a) Indemnification. In the event Vento or Sullivan (each, an "Indemnified
Party") is threatened to be made a party to any threatened, pending, or
completed action, suit, or proceeding (a "Proceeding"), whether civil, criminal,
administrative, or investigative (whether or not by or in the right of the
Company), by reason of the fact that such person is or was a director, officer,
incorporator, employee, or agent of the Company, or is or was serving at the
request of the Company as a director, officer, incorporator, employee, partner,
trustee, or agent of another corporation, partnership, joint venture, trust,

provided, however, that, if (and only if) required by the Delaware General
Corporation Law, such expenses incurred by or on behalf of any such Indemnified
Party may be paid in advance of the final disposition of a Proceeding only upon
receipt by the Company of an undertaking, by or on behalf of such Indemnified
Party, to repay any such amount so advanced if it shall ultimately be determined

such Indemnified Party is not entitled to be indemnified for such expenses.

signed by each of the parties.

      (f) Governing Law. This Agreement shall be governed by and construed in
accordance with the internal laws, and not the laws of conflict, of the State of
New York.

      (g) Severability. If any provision of this Agreement or the application
thereof to any person or circumstance shall for any reason or to any extent be
invalid or unenforceable, the remainder of this Agreement and the application of
such provision to other persons or circumstances shall not be affected thereby,
but, rather, shall be enforced to the extent permitted by law. Furthermore, in
lieu of such an illegal, invalid or unenforceable provision, there shall be
added automatically as part of this Agreement a provision as similar in terms to
such illegal, invalid or unenforceable provision as may be possible and be
legal, valid or enforceable.

      (h) Further Assurances. The parties agree that they will take all such
further actions and execute and deliver all such further instruments and

among the parties or any of them shall operate as a waiver of any such right,
power or privilege nor shall any single or partial exercise of any such right,
power or privilege preclude the simultaneous or later exercise of any other
right, power or privilege. The rights and remedies herein expressly provided are
cumulative and are not exclusive of any rights or remedies which the parties or
any of them would otherwise have.
