parties as follows:

1.    Representations and Warranties

      1.1   Employee represents and warrants that he is not subject to any

"Subsidiary," as hereafter defined), as the Board of Directors or the chief
operating officer of the Company may determine.

      2.2   Subject to Employee's election as such by the Board of Directors
and/or the Board of Directors of one or more subsidiaries, Employee agrees to
act and serve as a Vice President and Controller or other officer of the Company
and all applicable Subsidiaries and, if duly elected, agrees further to serve

his/her office, (ii) as an officer of any of the Subsidiaries and (iii) as a
director of the Company and of any Subsidiaries, and to comply with all
applicable laws relating to same.

Company, it being understood and agreed, however, that employee's base of
operations shall be his/her current office location and that Employee shall not
be required to render services on a permanent basis outside of said region
unless Employee otherwise agrees.

4.    Term

      4.1   Unless earlier terminated as provided in this Agreement, the term of
Employee's employment under this Agreement shall be for a period beginning on
the date hereof and ending on December 31, 2000 (the "Initial Term").

      4.2   The term of the Employee's employment under this Agreement shall be
automatically renewed for additional one-year terms (each a "Renewal Term") upon
the expiration of the Initial Term or any Renewal Term unless the Company or the
Employee delivers to the other, at least one hundred twenty (120) days prior to
the expiration of the Initial Term or the then current Renewal Term, as the case
may be, a written notice specifying that the term of the Employee's employment
will not be renewed at the end of the Initial Term or such Renewal Term, as the
case may be. The Initial Term or, in the event that the Employee's employment

this Section 4.2, such shorter or longer period, as the case may be, is
hereinafter called the "Term".

rendered and to be rendered by Employee hereunder and the fulfillment by
Employee of all of his/her obligations herein, the Company shall pay Employee a
base salary at the rate of One Hundred Forty Thousand Dollars ($140,000) per
year for each year of the Term on such days as the Company normally pays its
employees and subject to such withholdings as may be required by law (said
amount, together with any changes thereto as may be determined from time to time
by the Board of Directors of the Company in its sole discretion, being
hereinafter referred to as "Base Salary").

      5.2   Nothing herein shall prevent or preclude the Board of Directors of
the Company or the applicable committee of the Board of Directors, in its sole
discretion, and from time to time, from awarding a bonus or bonuses to Employee
for his/her service as an Employee and/or from awarding or granting Employee (i)
options to acquire shares of stock in the Company, (ii) shares of stock in the
Company or (iii) any other incentive or stock related awards in addition to Base
Salary. In exercising its discretion with respect to whether a bonus should be
awarded and the amount thereof, the Board or the applicable Committee may
consider, among other factors, the contribution of Employee (x) to the growth in
revenues, cash flow and subscribers of the Company and those subsidiaries to or
for which Employee renders service, (y) in connection with acquisitions and
financings, and (z) to the operations of the Company and its various
Subsidiaries as an entity.

6.    Reimbursement for Business Expenses; Fringe Benefits

      6.1   The Company agrees that all reasonable expenses incurred by Employee
in the discharge and fulfillment of his/her duties for the Company, as set forth

substantiation therefor signed by Employee, itemizing said expenses and

Company policy in effect from time to time.

      6.2   The Company agrees that it will cause Employee to be insured under
such group life, medical, major medical and disability insurance that the
Company may maintain and keep in force from time to time during the Term for the
benefit of all the Company's employees, subject to the terms, provisions and
conditions of such insurance and the agreements with underwriters relating to

or liability to Employee.

7.    Exclusivity; Non Solicitation

      7.1   During the Term, Employee agrees to devote his/her services and
his/her best energies and abilities, exclusively, to the business and activities
of the Company, including any Subsidiaries, and not engage or have an interest
in or perform services for any other business or entity of any kind or nature;
provided, however, that nothing herein shall prevent Employee from investing in
(but not rendering services to) other businesses which are not competitive in
any manner with the business then being conducted by the Company or any of its
Subsidiaries, or investing in (but not rendering services to) other businesses
(other than for charitable organizations, provided same does not interfere with
Employee's performance of his/her duties hereunder) which are competitive in any
manner with the business then being conducted by the Company, provided in the
latter instance, that (i) the shares of such business are listed and traded over
either a national securities exchange or in the over-the-counter market, and
(ii) stock interest or potential stock interest (based on grants, options,
warrants or other arrangements or agreements ten in existence) in any such
business which is so traded (together with any and all interest, actual and
potential, of all members of Employee's immediate family) is not a

                                       3
<PAGE>
controlling or substantial interest and specifically does not exceed one percent
of the issued and outstanding shares or a one percentage interest of or in such
business.

the end of the Term for any reason whatsoever, Employee will not directly or
indirectly induce or attempt to induce any employee of the Company or any of its
Subsidiaries to leave the employ of the Company or such Subsidiary, or in any
way interfere with the relationship between the Company and any of its
Subsidiaries and any employee thereof.

8.    Uniqueness

      8.1   Employee agrees that his/her services hereunder are special, unique
and extraordinary and that in the event of any material breach or attempted
material breach of this Agreement by Employee including, without limitation, the
provisions of Section 9 and/or 10, the Company will sustain substantial injury
and damage, and Employee hereby consents and agrees that, in the event of such
breach hereof, the Company shall be entitled to injunctive relief against
Employee or any third party to prevent or in respect of any such breach, in
addition to such other rights or remedies available to it.

9.    Trade Secrets

      9.1   Employee acknowledges that his/her employment hereunder will
necessarily involve his/her understanding of and access to certain trade secrets
and confidential information pertaining to the businesses and activities of the
Company and its Subsidiaries. Accordingly, Employee agrees that during the
period of employment and at all times thereafter, he will not disclose to any
unauthorized third party any such trade secrets or confidential information and
will not (other than in connection with carrying out his/her duties) for any
reason remove or retain without the express consent of the Company any figures
or calculation., letters, papers, records or other information of a type likely

his/her service, shall as between the parties hereto be, become and remain the
sole and exclusive property of the Company or any of its Subsidiaries, as the
case may be, for any and all purposes and uses whatsoever, regardless of whether
the same were invented, created, written, developed, furnished, produced or
disclosed by Employee or by any other party, and Employee shall have no right,
title of interest of any kind or nature therein or thereto, or in any results
and proceeds therefrom. Employee agrees during and after the term hereof to
execute any and all documents

                                       4
<PAGE>
which the Company may deem necessary and appropriate to effectuate the
provisions of this Section 10.1 and, further, that the provisions of this
Section shall survive the termination, for any reason, of this Agreement or

11.   Death - Permanent Incapacity

      11.1  The death of the Employee shall result in the immediate termination
of this Agreement.

      11.2  In the event Employee suffers a disability which prevents him from

            performance,
