location without the Executive's consent.

          1.4  The Term.  The term of the Executive's employment under this
               --------
Agreement (the "Term") shall commence on the date hereof and shall end on March

agreement between the Company and the Executive), unless earlier terminated as
hereinafter provided.

          2.  Compensation; Benefits.
              -----------------------

          2.1  (a) As compensation for services to be rendered pursuant to this

salary, payable in accordance with the Company's payment policy for executive
officers, at the annual rates set forth below, less such deductions or amounts
to be withheld as required by applicable law and regulations (the "Base
Salary"), plus such increases as may be implemented from time to time in
accordance with this Section 2.1(a).  Any increase in the Base Salary from the
annual rates set forth below shall be implemented by the Company only if
approved by the Board of Directors of the Company (or, if such Board delegates
such authority to its Compensation Committee, by such Compensation Committee)in
its discretion.  In the event that the Board (or such Compensation Committee, if
applicable), in its sole discretion , from time to time determines to increase
the Base Salary, such increased amount shall, from and after the effective date
of the increase, constitute "Base Salary" for purposes of this Agreement and
shall not thereafter be reduced except as otherwise contemplated by Section
2.1(b) hereof. The Executive shall be entitled to annual compensation reviews in
which all aspects of his compensation (including, without limitation, benefits)
will be compared with the compensation (including, without limitation, benefits)
of chief executive officers of similarly situated companies toward the objective
of providing the Executive with appropriate rewards and incentives.

          (b)  Subject to Section 2.1(a) hereof, for the period from January 1,
2000 through March 31, 2001, the Base Salary shall be not less than a rate of
Three Hundred Thousand Dollars ($300,000) per year.

          2.2  Bonus.  In addition to the amounts to be paid to the Executive
               -----
pursuant to Section 2.1, the Executive shall be eligible for an annual bonus.
The amount of the annual bonus shall be determined by the Board of Directors of
the Company (or, if such Board delegates such authority to its Compensation
Committee, by such Compensation Committee), in its sole discretion, and shall be
based upon the extent to which the Company has achieved financial goals approved
by the Board of Directors of the Company (or, if such Board delegates such
authority to its Compensation Committee, by such Compensation Committee). In the
event that the Company meets such goals, such annual bonus shall equal 100% of
the applicable Base Salary.  In the event that the Company fails to meet such
goals or exceeds such goals, the amount of such annual bonus shall be determined
by the Board of Directors of the Company (or, if such Board delegates such
authority to its Compensation Committee, by such Compensation Committee), in

                                      -2-

accordance with the guidelines established by the Board of the Directors of the
Company (or the Compensation Committee) with respect to the relationship between
bonus payments and the achievement of targeted goals, as a bonus that is less

exceeds such goals) 100% of the applicable Base Salary.

               -----------------
Executive for all expenses actually incurred or paid by the Executive during the
Term in the performance of the Executive's services under this Agreement, upon

information as the Company customarily may require of its officers.

          2.4  Vacation.  During the Term, the Executive shall be entitled to

               ---------------
for which the Executive shall be eligible under the Company's 1998 Stock

other so-called "fringe" benefit plan which the Company provides to its
employees generally, together with executive medical benefits for the Executive,
as from time to time in effect for executives of the Company generally.

without limitation, any failure to pay the compensation or provide the benefits
described in Section 2 hereof or any reduction in the Executive's position or
change in the nature of the Executive responsibilities from that contemplated in
Section 1.1 hereof or any relocation inconsistent with Section 1.3 hereof);

provided the Company has received written notice of such breach from the
--------
Executive, the Company has been given 30 days to cure such breach and the
Company has failed to effect such cure.

          (b)  For other than Good Reason.  The Executive may at any time, by
               --------------------------

(210) non-consecutive days during a period of three hundred and sixty-five (365)

(60) days after the Company ascertains that it has the right to terminate this
Agreement, in which case no further compensation or benefits shall be payable
hereunder except any as shall have been accrued to the date of such termination
or as required by law.

          3.4  Severance.  In the event this Agreement is terminated (i) by the
               ---------
Company for other than Cause or (ii) by the Executive for Good Reason, the
Executive shall be entitled to receive his salary at the rate in effect
immediately prior to such termination (pursuant to Section 2.1), a bonus equal

event that the Company  fails to pay (within five days after  receiving  written
notice of default) any amount required to be paid to Executive  pursuant to this
Section  3.4,  the  Executive  shall have no further  obligation  to comply with
Section 4 hereof; provided,  however, that if the Company fails to make any such
payments due to a lack of sufficient  financial resources to make such payments,
(i) the Executive  shall remain  obligated to comply with Section 4 hereof for a
period of ninety days after the Company first defaults in its obligations  under
this  Section 3.4 (but in no event for a period  expiring  after the last day in

and (ii) the  Executive  shall not solicit any  employee of the Company to leave

         4.1  The Executive covenants and agrees that he shall not, directly or
indirectly, anywhere within the United States or Canada, (1) become "Associated
With" any "Competing Business" or (2) solicit, sell, call upon or induce others
to solicit, sell or call upon, directly or indirectly, any customer or
prospective customer of the Company for the purpose of inducing any such
customer or prospective customer to purchase, license or lease a product or

Section 4 shall preclude Executive from becoming "Associated With" an entity

predominantly in the business of providing telephony services to retail (and not
wholesale) customers and does not otherwise satisfy the definition of a
"Competing Business"  below, or (b) as part of its overall business, engages in
the provision of Internet telephony services to wholesale customers if and only
if (A) Executive's responsibilities in connection with Executive's association
with such entity do not include the provision of such Internet telephony
services and (B) the provision of Internet telephony services to wholesale
customers does not represent a substantial portion of such entity's overall
business activities.  For purposes of this Agreement, the following terms shall
have the following meanings:

     "Competing Business" means the business of any person, corporation (for
     profit or not for profit) or other entity which indirectly or directly
     provides Internet telephony services, including without limitation, (i)
     linking Internet telephone service providers ("ITSPs") to each other; (ii)
     providing billing and settlement services to Internet telephony customers;
     and/or (iii) connecting participating ITSPs to telephone numbers using a
     combination of Internet providers and traditional telephony for wholesale
     or retail customers.

     "Associated With" means serving as an owner, officer, employee, independent
     contractor, agent or a holder of 5% or more of any class of equity
     securities of, director, trustee, member, consultant or partner of any
     person, corporation (for profit or not for profit) or other entity engaged
     in a Competing Business.

         4.2  Non-compete Period.
              ------------------

                                      -5-
<PAGE>

          (a) The covenant not to compete set forth in Section 4.1 of this
Agreement shall restrict the Executive from the date of this Agreement until the
earliest of: (i) two (2) years following termination of this Agreement by the
Company for Cause; (ii) six (6) months following termination of this Agreement
by the Company other than for Cause; (iii) six (6) months following the
Executive's resignation with Good Reason prior to the expiration of the Term;
(iv) six (6) months following the Executive's resignation without Good Reason
prior to the expiration of the Term; and (v) upon termination of this Agreement,
if this Agreement terminates pursuant to Section 3.3 hereof or upon expiration
of the Term.  Notwithstanding anything contained herein to the contrary, the
Company may, at its option, elect to extend the non-compete period set forth in
clauses (ii), (iii) and (iv) above, respectively, for successive periods of six
(6) months each (each such six (6) month period being referred to herein as an
"Extension Period"); provided, however, that no such extension shall be
                     --------  -------
effective unless the Company provides written notice of such extension to the
Executive at least thirty (30) days prior to the date that the non-compete
period is due to expire; and provided further that in no event shall the non-
                             -------- -------
compete period (including the initial non-compete period and any Extension
Periods) exceed two (2) years in the aggregate.

          (b) In the event that the Company elects to extend the Non-Compete
Period pursuant to Section 4.2(a) above,  (a) the Severance Period set forth in
Section 3.4 shall continue until the end of the Extension Period and (b) the
Company shall pay the Executive during any Extension Period his salary at the
rate in effect immediately prior to the termination of the Executive's
employment hereunder (pursuant to Section 2.1), a bonus equal to 100% of such
salary and all other benefits then afforded to the senior executive officers of
the Company, paid at the Company's option in bi-weekly or monthly installments.

          4.3  If any of the covenants contained in Sections 4.1 or 4. 2, or any
part thereof, hereafter are construed to be invalid or unenforceable, the same
shall not affect the remainder of the covenant or covenants, which shall be
given full effect, without regard to the invalid portions.

         4.4  If any of the covenants contained in Sections 4.1, 4.2 or 5, or
any part thereof, are held to be unenforceable because of the duration of such
provision or the area covered thereby, the parties agree that the court making
such determination shall have the power to reduce the duration and/or area of
such provision to the maximum extent possible and, in its reduced form, said
provision shall then be enforceable.

         4.5  The parties hereto intend to and hereby confer jurisdiction to
enforce the covenants contained in Sections 4.1 and 4.2 upon the courts of any
state within the geographical scope of such covenants.  In the event that the
courts of any one or more of such states shall hold such covenants wholly
unenforceable by reason of the breadth of such covenants or otherwise, it is the
intention of the parties hereto that such determination not bar or in any way
affect the Company's right to the relief provided above in the courts of any
other states within the geographical scope of such covenants as to breaches of
such covenants in such other respective jurisdictions, the above covenants as
they relate to each state being for this purpose severable into diverse and
independent covenants.

                                      -6-
<PAGE>

         4.6.  In the event that any action, suit or other proceeding in law or
in equity is brought to enforce the covenants contained in Sections 4.1 and 4.2
or to obtain money damages for the breach thereof, and such action results in
the award of a judgment for money damages or in the granting of any injunction
in favor of the Company, all expenses (including reasonable attorneys' fees) of
the Company in such action, suit or other proceeding shall (on demand of the
Company) be paid by the Executive.  In the event the Company fails to obtain a
judgment for money damages or an injunction in favor of the Company, all
expenses (including reasonable attorneys' fees) of the Executive in such action,
suit or other proceeding shall (on demand of the Executive) be paid by the
Company.
