     (c)  EMPLOYMENT TERM.  Employee's employment hereunder (the "Employment
Term") shall commence on the date hereof.  Such employment shall be "at will"
employment pursuant to applicable law.  If Employee's employment terminates for
any reason other than (i) voluntary termination by Employee, (ii) termination as
a result of death or disability, or (iii) termination for Cause (as defined in
Section 5(a)), Employee shall be entitled to sixty (60) days notice of

during the Employment Term and shall perform such duties diligently, in good
faith and consistent with the best interests of Unitech.

2.   COMPENSATION.

     (a)  SALARY.  During the Employment Term, Employee will receive a salary
of not less than $7,500 per month ($90,000 per annum), which shall be paid in
accordance with Unitech's normal payroll practice and shall be subject to
review based upon Unitech's normal performance review practices.  Unless
otherwise specified herein, Unitech will make such deductions, withholdings
and other payments from all sums payable pursuant to this Agreement which
Employee requests or which are required by applicable law for taxes and other
charges. Unitech shall, in addition to Employee's salary, reimburse Employee
for all ordinary and necessary out-of-pocket expenses incurred by him in the
performance of his services under this Agreement, subject to and upon receipt
by Unitech of invoices or other documentation in support thereof in
accordance with Unitech's policies regarding reimbursement of expenses.
Employee shall be entitled to receive such bonus as shall be approved by the
Board of Directors of Unitech in each year during the Employment Term.

     (b)  BENEFIT PLANS.  Employee will be entitled to participate in or

                                         -2-
<PAGE>

terms and conditions of the particular benefit plan.  These benefit plans may
include health care, life insurance, accidental death and disability, short-
and long-term disability, stock options, savings and/or bonus plans provided
by, through or on behalf of Unitech.  Unitech may change, amend, modify or
terminate any benefit or bonus plan from time to time.

     3.   CONFIDENTIALITY AND PROPRIETARY INFORMATION AGREEMENT.  Concurrently
with the execution of this Agreement, Unitech and Employee will execute the
Confidentiality and Proprietary Information Agreement ("Confidentiality
Agreement") in the form attached hereto as Attachment 1.

     4.   COVENANT NOT TO COMPETE.

          (a)  NON-COMPETE.  In consideration of his employment, Employee
agrees that so long as he is an Employee of Unitech and, in the case of
Employee's termination of employment with Unitech, two (2) years from the
date of termination, Employee will not directly or indirectly engage in
(whether as an employee, consultant, proprietor, partner, director or
otherwise), or have any ownership interest in, or participate in the
financing, operation, management or control of, any person, firm, corporation
or business that engages in a "Restricted Business" in a "Restricted
Territory" (as such terms are herein defined).  It is agreed that ownership
of no more than 1% of the outstanding voting stock of a publicly traded
corporation shall not constitute a violation of this provision.  It is also
agreed that this provision shall not apply if the Employee's termination of
employment with Unitech is due to (i) a breach by Unitech of the terms of
this Agreement as adjudicated by a court of competent jurisdiction (except
for a failure of Unitech to pay Employee's salary as provided in Section 2(a)
hereof which, for these purposes, will not require such adjudication) or (ii)
a final adjudication of Unitech as a bankrupt under any federal or state law.

          (b)  NON-SOLICIT.  Employee agrees that until the later to occur of
(i) the termination of Employee's agreement not to compete pursuant to
Section 4(a) above (ii) 2 years following the termination of Employee's
employment with Unitech, Employee shall not solicit, encourage, or take any
other action which is intended to induce any other employee of Unitech or
StarCom to terminate his employment with Unitech.

          (c)  SEVERABILITY.  The parties intend that the covenants contained in
the preceding paragraphs shall be construed as a series of separate covenants,
one for each county, city, state and other political subdivision of the
Restricted Territory.  Except for geographic coverage, each such separate
covenant shall be deemed identical in terms to the covenant contained in the
preceding paragraphs.  If, in any judicial proceeding, a court shall refuse to
enforce any of the separate covenants (or any part thereof) deemed included in
said paragraphs, then such unenforceable covenant (or such part) shall be deemed
eliminated from this Agreement for the purpose of those proceedings to the
extent necessary to permit the remaining separate covenants (or portions
thereof) to be enforced by such court.  It is the intent of the parties that the
covenants set forth herein be enforced to the maximum degree permitted by
applicable law.

          (d)  REFORMATION.  In the event that the provisions of this Section 4
should ever be deemed to exceed the scope, time or geographic limitations of
applicable law regarding covenants not to compete, then such provisions shall be
reformed to the maximum scope, time or geographic limitations, as the case may
be, permitted by applicable laws.

          (e)  REMEDIES.  The Employee hereby acknowledges that the covenants
and restrictions contained in this Section 4 are necessary for the protection
of Unitech's business and goodwill and are considered by the Employee to be
reasonable.  Accordingly, the Employee hereby acknowledges and agrees that
any actual or threatened breach of any of the provisions of such Paragraph 4
may cause irreparable harm to Unitech and may not be remediable by an action
at law for damages and, therefore, Unitech shall be entitled to seek, as a
non-exclusive remedy, in any court of competent jurisdiction, all equitable
remedies therefor, including, without limitation, a temporary or permanent
injunction or specific performance of the provisions hereof, without the
necessity of showing any actual damage or that monetary damages would not
provide an adequate remedy at law or posting a bond therefor.

               The Employee covenants and agrees that, if the Employee shall
violate the foregoing non-compete covenant,  Unitech shall be entitled to an
accounting and repayment of all profits, compensation, commissions,
remunerations, benefits or other payments which the Employee directly or
indirectly has realized and/or may realize as a result of, growing out of or
in connection with any such violation.  Such remedy shall be in addition to
and not in limitation of any injunctive relief or other rights or remedies to
which Unitech may be entitled at law or in equity or under this Agreement.

     5.   Employee agrees that he shall not knowingly and intentionally
interfere in any manner with the contractual or employment relationship
between Unitech or StarCom and any employee, supplier or customer of Unitech.
