     the Date of Termination.

          (c)  Termination Without Cause or for Company Breach. If Employer
               -----------------------------------------------
     shall terminate the Employee's employment Without Cause or if the Employee
     shall terminate his employment for Company Breach, then Employer shall pay
     to the Employee, as severance pay in a lump sum on the 15th day following
     the Date of Termination, the following amounts:

               (i)   his accrued but unpaid Base Salary through the Date of
          Termination at the rate in effect as of the Date of Termination; and

               (ii)  in lieu of any further Base Salary and Annual Incentive
          Payments for periods subsequent to the Date of Termination, an amount
          equal to the product of (A) the sum of Employee's Base Salary at the
          rate in effect as of the Date of Termination plus the amount of the
          Annual Incentive Payment paid to the Employee for the preceding year
          (or an annualized equivalent of the Annual Incentive Payment paid for
          any shorter period) divided by 365 and (B) multiplied by the lesser of
          (y) 720, or (z) the number of days from the Date of Termination to the
          last day of the Original Term or the applicable renewal term, but in
          no event less than 365 days.

          In addition, the Employee will be entitled to a prorated portion of
     any annual incentive payment earned for the fiscal year in which his
     employment is terminated, if earned in accordance with the terms of its
     grant.

          Employee hereby acknowledges and agrees that the payments by the
     Employer under this Section 1.6(c) shall be the sole and exclusive remedy
     of the Employee for termination

                                       8
<PAGE>

     of Employee's employment Without Cause or by reason of a Company Breach,
     and Employee hereby waives any and all other remedies under law or in
     equity.

          If the Employee terminates his employment for Company Breach based
     upon a material reduction by Employer of the Employee's Base Salary, then
     for purposes of this subsection 1.6(c) (Termination Without Cause or for
                                             --------------------------------
     Company Breach), the Employee's Base Salary as of the Date of Termination
     --------------
     shall be deemed to be the Employee's Base Salary immediately prior to the
     reduction that the Employee claims as grounds for Company Breach.

          (d)  Termination Upon a Change in Control. If the Employee terminates
               ------------------------------------
     his employment after a Change in Control pursuant to subsection 1.5(e)
     (Change in Control), then Employer shall pay to the Employee as severance
      -----------------
     pay and as liquidated damages (because actual damages are difficult to
     ascertain), in a lump sum, in cash, within 15 days after termination, an
     amount which, when combined with all payments under Section 1.6(c), equals
     $100 less than three (3) times the Employee's "annualized includable
     compensation for the base period" (as defined in Section 280G of the
     Internal Revenue Code of 1986); provided, however, that if such lump sum
                                     --------  -------
     severance payment, either alone or together with other payments or
     benefits, either cash or non-cash, that the Employee has the right to
     receive from Employer, including, but not limited to, accelerated vesting
     or payment of any deferred compensation, options, stock appreciation rights
     or any benefits payable to the Employee under any plan for the benefit of
     employees, would constitute an "excess parachute payment" (as defined in
     Section 280G of the Internal Revenue Code of 1986), then such lump sum
     severance payment or other benefit shall be reduced to the largest amount
     that will not result in receipt by the Employee of a parachute payment.
     The determination of the amount of the payment described in this subsection
     shall be made by Parent's independent auditors.

          (e)  Termination for Disability. If Employer shall terminate the
               --------------------------
     Employee's employment for Disability, Employer's obligation to pay salary
     and benefits pursuant to Section 1.4 (Compensation) shall terminate, except
                                           ------------
     that Employer shall pay the Employee accrued but unpaid salary and benefits
     pursuant to Section 1.4 (Compensation) through the Date of Termination,
                              ------------
     after giving effect to all disability benefits received by Employee under
     the terms of any applicable disability policy.

          (f)  Employee Benefits. Employer shall maintain in full force and
               -----------------
     effect (to the extent consistent with past practice), for the continued
     benefit of Employee and, if applicable, his wife and children, the employee
     benefits set forth in subsections 1.4(f) (Fringe Benefits and Perquisites)
                                               -------------------------------
     through the Date of Termination (subject to the provisions of Section
     1.6(e)); provided that his continued participation or, if applicable, the
     participation of his wife and children, is possible under the general terms
     and conditions of such plans and programs. Following the Date of
     Termination, Employee and his eligible dependents shall be eligible for
     continued health coverage in accordance with the terms of applicable law.

     1.7  Death of Employee. If Employee dies prior to the expiration of this
          -----------------
Agreement, Employee's employment and other obligations under this Agreement
shall automatically terminate and all compensation to which Employee is or would
have been entitled hereunder (including without limitation under subsections
1.4(a) (Base Salary) and 1.4(b) (Annual Incentive Payment)) shall terminate as
        -----------              ------------------------
of the end of the month in which Employee's death occurs; provided, however,
                                                          --------  -------
that (i) Employer shall pay to Employee's estate, as soon as practicable, a
prorated Annual Incentive Payment, if earned in accordance with Parent's annual
incentive plan; and (ii) for the balance of the month in which Employee's death
occurs, Employee's wife and children shall be entitled to receive their benefits
under Employer's group hospitalization, medical and dental plans (if any), to
the extent permitted under the terms of such plans, and thereafter Employee's
dependents shall have a right to continued health coverage in accordance with
the terms of applicable law.

          operation or control of, be employed by, associated or in any manner

     Competition) is overly restrictive and unenforceable, the court may reduce
     -----------
     or modify such restrictions to those which it deems reasonable and
     enforceable under the circumstances, and as so reduced or modified, the
     parties hereto agree that the restrictions of this Section 2.4 (Non-
                                                                     ---
     Competition) shall remain in full force and effect. The Employee further
     -----------
     agrees that if a court of competent jurisdiction determines that any
     provision of this Section 2.4 (Non-Competition) is invalid or against
                                    ---------------
     public policy, the remaining provisions of this Section 2.4 (Non-
                                                                  ---
     Competition) and the remainder of this Agreement shall not be affected
     -----------
     thereby, and shall remain in full force and effect.

          (c)  Nature of Restrictions. The Employee acknowledges that the
               ----------------------
     business of Employer and Parent and their Affiliates is international in
     scope and that the Restrictions imposed by this Agreement are legitimate,
     reasonable and necessary to protect Employer's, Parent's and their
     Affiliates' investment in their businesses and the goodwill thereof. The
     Employee acknowledges that the scope and duration of the restrictions
     contained herein are reasonable in light of the time that the Employee has
     been or will be engaged in the business of Employer, Parent and/or their
     Affiliates, and the Employee's relationship with the suppliers, customers
     and clients of Employer, Parent and their Affiliates. The Employee further
     acknowledges that the restrictions contained herein are not burdensome to
     the Employee in light of the consideration paid therefor and the other
     opportunities that remain open to the Employee. Moreover, the Employee
     acknowledges that he has other means available to him for the pursuit of
     his livelihood.

          (d)  Competing Business. "Competing Business" shall mean any
               ------------------
     individual, business, firm, company, partnership, joint venture,
     organization, or other entity engaged in the wholesale distribution or
     retail sales of wireless communication equipment in any domestic or
     international market area in which Employer, Parent or any of their
     Affiliates does business at any time during the Employee's employment with
     Employer or any of its Affiliates.

     2.5  Injunctive Relief. Because of the Employee's experience and
          -----------------
reputation in the industries in which Employer, Parent and their Affiliates
operate, and because of the unique nature of the Confidential Information, the
Employee acknowledges, understands and agrees that Employer and Parent will
suffer immediate and irreparable harm if the Employee fails to comply with any
of his obligations under Article 2 (Non-Competition and Confidentiality) of this
                                    -----------------------------------
Agreement, and that monetary damages will be inadequate to compensate Employer
and Parent for such breach. Accordingly, the Employee agrees that Employer and
Parent shall, in addition to any other remedies available to them at law or in
equity, be entitled to injunctive relief to enforce the terms of Article 2

                                       13

benefits so afforded by such change.

Agreement, shall be exclusively and finally settled by arbitration, and any
party may submit such dispute, controversy or claim, including a claim for
indemnification under this Section 5.9 (Dispute Resolution), to arbitration.
                                        ------------------

          (a)  Arbitrators. The arbitration shall be heard and determined by one
               -----------
     arbitrator, who shall be impartial and who shall be selected by mutual
     agreement of the parties; provided, however, that if the dispute involves
                               --------  -------
     more than $2,000,000, then the arbitration shall be heard and determined by
     three (3) arbitrators. If three (3) arbitrators are necessary as provided
     above, then (i) each side shall appoint an arbitrator of its choice within
     thirty (30) days of the submission of a notice of arbitration and (ii) the
     party-appointed arbitrators shall in turn appoint a presiding arbitrator of
     the tribunal within thirty (30) days following the appointment of the last
     party-appointed arbitrator. If (x) the parties cannot agree on the sole
     arbitrator, (y) one party refuses to appoint its party-appointed arbitrator
     within said thirty (30) day period or (z) the party-appointed arbitrators
     cannot reach agreement on a presiding arbitrator of the tribunal, then the
     appointing authority for the implementation of such procedure shall be the
     Senior United States District Judge for the Northern District of Texas, who
     shall appoint an independent arbitrator who does not have any financial
     interest in the dispute, controversy or claim. If the Senior United States
     District Judge for the Northern District of Texas refuses or fails to act
     as the appointing authority within ninety (90) days after being requested
     to do so, then the appointing authority shall be the Chief Executive
     Officer of the American Arbitration Association, who shall appoint an
     independent arbitrator who does not have any financial interest in the
     dispute, controversy or claim. All decisions and awards by the arbitration
     tribunal shall be made by majority vote.

          (b)  Proceedings. Unless otherwise expressly agreed in writing by the
               -----------
     parties to the arbitration proceedings:

               (i)    The arbitration proceedings shall be held in Dallas,
          Texas, at a site chosen by mutual agreement of the parties, or if the
          parties cannot reach agreement on a location within thirty (30) days
          of the appointment of the last arbitrator, then at a site chosen by
          the arbitrators;

               (ii)   The arbitrators shall be and remain at all times wholly
          independent and impartial;

               (iii)  The arbitration proceedings shall be conducted in
          accordance with the Commercial Arbitration Rules of the American
          Arbitration Association, as amended from time to time;

               (iv)   Any procedural issues not determined under the arbitral
          rules selected pursuant to item (iii) above shall be determined by the
          law of the place of arbitration, other than those laws which would
          refer the matter to another jurisdiction;

               (v)    The costs of the arbitration proceedings (including
          attorneys' fees and costs) shall be borne in the manner determined by
          the arbitrators;

               (vi)   The decision of the arbitrators shall be reduced to
          writing; final and binding without the right of appeal; the sole and
          exclusive remedy regarding any claims, counterclaims, issues or
          accounting presented to the arbitrators; made and promptly paid in
          United States dollars free of any deduction or offset; and any costs
          or fees incident to enforcing the award shall, to the maximum extent
          permitted by law, be charged against the party resisting such
          enforcement;

               (vii)  The award shall include interest from the date of any
          breach or violation of this Agreement, as determined by the arbitral
          award, and from the date of the award until paid in full, at 6% per
          annum; and

               (viii) Judgment upon the award may be entered in any court having
          jurisdiction over the person or the assets of the party owing the
          judgment or application may be made to such court for a judicial
          acceptance of the award and an order of enforcement, as the case may
          be.

     5.10 Survival. The covenants and agreements of the parties set forth in
          --------
Article 2 (Non-Competition and Confidentiality), and Article 5 (Miscellaneous)
           -----------------------------------                  -------------
are of a continuing nature and shall survive the expiration, termination or
cancellation of this Agreement, regardless of the reason therefor.

     5.11 Subrogation. In the event of payment under this Agreement, Employer
          -----------
and Parent shall be subrogated to the extent of such payment to all of the
rights of recovery of the Employee, who shall execute all papers required and
shall do everything that may be necessary to secure such

                                       17
<PAGE>

rights, including the execution of such documents necessary to enable Employer
or Parent effectively to bring suit to enforce such rights.

     5.12 No Duplication of Payments. Employer and Parent shall not be liable
          --------------------------
under this Agreement to make any payment in connection with any claim made
against the Employee to the extent the Employee has otherwise actually received
payment (under any insurance policy, Bylaw or otherwise) of the amounts
otherwise indemnifiable hereunder.

     5.13 Binding Effect, Etc. This Agreement shall be binding upon and inure to
          --------------------
the benefit of and be enforceable by the parties hereto and their respective
successors, assigns, including any direct or indirect successor by purchase,
merger, consolidation or otherwise to all or substantially all of the business
or assets of Employer, Parent, spouses, heirs, and personal and legal
representatives. Employer and Parent shall require and cause any successor
(whether direct or indirect by purchase, merger, consolidation or otherwise) to
all, substantially all, or a substantial part, of their business or assets, by
written agreement in form and substance satisfactory to the Employee, expressly
to assume and agree to perform this Agreement in the same manner and to the same
extent that Employer or Parent would be required to perform if no such
succession had taken place.

     5.14 Contribution. If the indemnity contained in this Agreement is
          ------------
unavailable or insufficient to hold the Employee harmless in a Claim for an
Indemnifiable Event, then separate from and in addition to the indemnity
provided elsewhere herein, Parent shall contribute to Expenses, judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by or on behalf of the Employee in connection with such Claim in such proportion
as appropriately reflects the relative benefits received by, and fault of,
Parent on the one hand and the Employee on the other in the acts, transactions
or matters to which the Claim relates and other equitable considerations.

     5.15 Parent Guaranty. Parent guarantees the payment and performance of all
          ---------------
obligations of Employer under this Agreement and agrees it will pay or perform
those obligations if for any reason Employer fails to do so. This guarantee is
absolute, continuing, irrevocable and not conditional or contingent. Any notice
given hereunder to either Employer or Parent will be deemed to be notice to
Parent for purposes of this guaranty.
