and conditions of Executive's employment by the Company from and after the
Commencement Date; and

                  WHEREAS, the Executive desires to continue in the
employment of the Company from and after the Commencement Date under those
terms and conditions;

                  NOW, THEREFORE, in consideration of the mutual covenants
herein contained, the Company and Executive hereby agree as follows:

1.       EMPLOYMENT.

         (a) AGREEMENT TO EMPLOY. Upon the terms and subject to the
conditions of this Agreement, the Company hereby employs Executive, and
Executive hereby accepts continued employment by the Company.

         (b) TERM OF EMPLOYMENT. The Company shall employ Executive for a
term (the "Term") commencing on the Commencement Date and ending on July 30,
2003, unless extended by a written agreement signed by both parties. The
period commencing on the Commencement Date and ending on the earlier of (i)
the expiration of the Term, or (ii) the date of Executive's termination of
employment pursuant to Section 5(a) shall be referred to as the "Employment
Period".

2.       POSITION AND DUTIES.

         (a) IN GENERAL. Executive shall be employed as Executive VP of
Technology and shall perform such duties and services, consistent with such
position and his current duties and services for the Company, and as may be
assigned to him from time to time by the Chief Executive Officer (the "CEO")
of the Company. The duties of the Executive shall include serving as an
officer or director or otherwise performing services for any "Affiliate" of
the Company as requested by the Company. An "Affiliate" of the Company means
any entity that controls, is controlled by or is under common control with
the Company. Executive shall report to the CEO.



         (b) FULL-TIME EMPLOYMENT. During the Employment Period, Executive
shall devote his full business time to the services required of him
hereunder, except for time devoted to services required by him to be
performed for any "Affiliate" of the Company, vacation time and reasonable
periods of absence due to sickness, personal injury or other disability, and
shall use his reasonable best efforts, judgment, skill and energy to perform
such services in a manner consonant with the duties of his position and to
improve and advance the business and interests of the Company. Executive
shall not be engaged in any other business activity which, in the reasonable
judgment of the CEO, conflicts with the duties of the Executive under this
Agreement. In such event, Executive shall receive five days' written notice
to disengage from such business activity. Executive may serve on the Board of
Directors or on advisory boards of other corporations which do not compete
with the Company; PROVIDED, HOWEVER, that, in such case, (i) Executive shall
provide the Company with 5 days' written notice of any scheduled meeting of
the Board of Directors of such company and (ii) Executive shall be charged
with 1/2 vacation day for every four hours spent at such Board of Directors
meeting during business hours. Executive shall travel to such location or
locations as may be requested by the Company, or which Executive believes is
necessary or advisable, in the performance by Executive of his duties
hereunder or to the extent appropriate to improve and advance the interests
of the Company and its Affiliates. There is no formal disciplinary procedure,
but Executive is expected at all times to behave in a manner befitting his
employment.

3.       COMPENSATION.

         (a) BASE SALARY. During the Employment Period, the Company shall pay
Executive a base salary at the annual rate of US$170,000 ; PROVIDED that
Executive's annual base salary shall be increased as of January 1 of each
year, commencing January 1, 2001, by an amount equal to the base salary then
in effect, multiplied by the percentage increase in the Cost of Living Index
during the preceding year. The "Cost of Living Index" means the consumer
price index for all urban consumers in the New York metropolitan area
published by the Department of Labor, or if such index is no longer
available, such other generally available index measuring changes in consumer
purchasing power (in the New York metropolitan area or nationally) designated
by the Board of Directors. Any delay in increase in Executive's annual base
salary by reason of the unavailability of any such index at the time any such
increase shall otherwise be due shall be made up by a lump sum payment
promptly after the index becomes available. Executive's salary, as adjusted
for any increase in the Cost of Living Index, may be further increased at the
option and in the discretion of the Board of Directors (such salary, as the
same may be increased from time to time, is referred to herein as the "Base
Salary"). The Base Salary shall be payable in such installments (but not less
frequent than monthly) as the salaries of other executives of the Company are
paid.

         (b) PERFORMANCE INCENTIVE PLAN. During the Employment Period,
Executive shall be eligible to participate in the Company's 1999 Performance
Incentive Plan. The discretionary portion of the bonus shall be determined by
the Compensation Committee. If the Company shall amend or terminate the 1999
Performance Incentive Plan in a manner that would reduce the



opportunity of Executive to earn an incentive bonus as provided in the 1999
Performance Incentive Plan, the Company shall provide a substitute
arrangement so that Executive's total bonus opportunity will not be
materially reduced. In addition to you your base salary set forth herein, the
Company will provide you with a one-time $25,000 signing bonus. Such signing
bonus shall be less all applicable taxes and will be included in the third
pay check you receive after you start working for the Company

         (c) STOCK INCENTIVE PLAN. The Company shall grant Executive an award
of stock options (the "Option") to purchase 173,938 shares of the Company's
Class A Common Stock (the "Common Stock") at an exercise price equal to US$6
15/16 per share, the Fair Market Value (as defined under the 1999 Stock
Incentive Plan) on the date of grant. The Option shall be governed by, and
fall under, the Company's 1999 Stock Incentive Plan. The Option shall become
exercisable as set forth below, PROVIDED that Executive is employed by the
Company on such date, and once exercisable shall, except as otherwise
provided below, remain exercisable until the expiration of seven years from
the date of grant. However, the Option shall be immediately terminated upon a
termination of Executive's employment by the Company for Cause (as
hereinafter defined):



           Date First Exercisable                      Percentage Exercisable
           ----------------------                      ----------------------
                                                    
First Anniversary of the Commencement Date                            33-1/3%
Second Anniversary of the Commencement Date                           66-2/3%
Third Anniversary of the Commencement Date                            100%


         The Option shall become immediately exercisable in full in the event
that Executive's employment with the Company is terminated: (i) by the
Company other than for Cause, (ii) by Executive for Good Reason or (iii) by
reason of the death or Disability of the Executive; PROVIDED, HOWEVER, that
if Executive's employment is terminated for any reason prior to the 18 month
anniversary of the Commencement Date, only the exercisable portion of the
Option, if any, shall remain exercisable and any unvested portion of the
Option shall not be exercisable. The Option shall expire on the seven-year
anniversary of the Commencement Date.

         Additionally, the Option shall become immediately exercisable in
full upon a Change in Control. The exercisable portion of the Option shall,
following any termination of Executive's employment (other than for Cause),
remain exercisable for the lesser of two years and the remaining term of the
Option.

4.       BENEFITS, PERQUISITES AND EXPENSES.

         (a) BENEFITS. During the Employment Period, Executive shall be
eligible to participate in (i) each welfare benefit plan sponsored or

         (c) BUSINESS EXPENSES. During the Employment Period, the Company
shall pay or reimburse Executive for all reasonable expenses incurred or paid
by Executive in the performance of Executive's duties hereunder, upon

other capacity, including any fiduciary capacity, in which Executive serves
at the request of the Company to the maximum extent permitted by applicable
law and the Company's Certificate of Incorporation and Bylaws in effect on
the date hereof. If any claim is asserted against Executive with respect to
which Executive reasonably believes in good faith he is entitled to
indemnification, the Company shall either defend Executive or, at its option,
pay Executive's legal expenses (or cause such expenses to be paid) on a
quarterly basis, PROVIDED that Executive shall reimburse the Company for such
amounts, plus simple interest thereon at the 90-day United States Treasury

that request and cooperate to the maximum extent authorized by law with the
Company in protecting the Company's and it Affiliates' interest in

incurred by Executive in connection with his cooperation with the Company and

without Cause or otherwise.

12.      ARBITRATION OF ALL DISPUTES

         (a) Any dispute, controversy or claim between the Executive and the
Company or any of its officers, directors, employees or shareholders (who are
expressly made third-party beneficiaries of this agreement) arising out of,
relating to or in connection with this agreement, or the breach, termination
or validity thereof, shall be finally resolved by binding and non-appealable
arbitration, before a single arbitrator selected by the procedure set forth
below, conducted in New York, New York.

         (b) Either party may commence an arbitration proceeding by giving
written notice to the other party of its desire to arbitrate.

         (c) The single arbitrator (the "Arbitrator") shall be selected from
among the New York City members of the New York Regional Panel of
Distinguished Neutrals (the "Panel") of the Center for Public Resources
("CPR") by mutual agreement of the parties, or if the parties are unable to
agree, by the following means:

                                    (A) The Company, on one hand, and Executive
                  on the other hand, shall simultaneously exchange lists each
                  containing the names of five members of their choice of the
                  Panel who have indicated a willingness to serve.

                                    (B) If a single name appears on both lists,
                  that individual shall be appointed.

                                    (C) If more than one name appears on both
                  parties' lists, the Arbitrator shall be selected from the
                  common names by mutual agreement of the parties or by the toss
                  of a coin.

                                    (D) If the lists contain no names in common,
                  each party shall strike four names from the other party's list
                  and the Arbitrator shall be selected from the remaining two
                  names by mutual agreement of the parties or by the toss of a
                  coin.



                                    (E) If the CPR ceases to have a Panel or it
                  is otherwise impossible to select the Arbitrator from the
                  Panel as contemplated by this Agreement, the Arbitrator shall
                  be selected by the President of the CPR in the manner that the
                  President deems closest to satisfying the purposes of this
                  Section, or, if such person is unable to do so, by the
                  President of the Association of the Bar of the City of New
                  York.

         (d) The Arbitrator, after appropriate consultation with the parties,
shall (i) determine, in his or her sole discretion, the rules governing the
arbitration proceeding, including whether and to what extent the parties
shall have any right to pre-hearing discovery or other forms of disclosure,
the manner of presentation of arguments and/or evidence before or at any
hearing, whether and to what extent formal rules of evidence shall govern the
proceeding and the parties' rights following the proceeding, and (ii) be
governed in exercising such discretion by the goal of reaching a fair and
reasonable decision in an expeditious and efficient manner while endeavoring
to streamline the process and avoid undue litigation costs.

         (e) The Arbitrator shall assess the costs of the proceeding
(including the prevailing party's reasonable attorney's fees) on any
unsuccessful party to the extent the Arbitrator concludes that such party is
unsuccessful, unless he or she concludes that (i) matters of equity or
important considerations of fairness dictate otherwise or (ii) in the case of
Executive, the Arbitrator determined that Executive acted reasonably and in
good faith in pursuing all of the claims asserted by him in such arbitration.

         (f) The Arbitrator shall be required to state his or her decision in
writing and may, but shall not be required to, elaborate on the reasons for
such decision.

         (g) The arbitrator(s) shall have the authority upon application by a
party to direct specific performance, including preliminary or interim
specific performance pending the final resolution of the arbitration, of any
portion of this agreement. The parties expressly consent to the jurisdiction
and power of any federal or state court in New York to enforce the terms of
such a direction upon application by a party. If the arbitrator(s) have not
yet been appointed, the parties may obtain injunctive or other appropriate
relief from a court to enforce the terms of this agreement pending the
appointment of the arbitrator(s) who shall thereafter have full power to
continue, modify or vacate the terms of any injunctive relief ordered by the
court.

         (h) Notwithstanding the terms of this agreement that provide that
New York law shall govern, the arbitration and the provisions in this
agreement dealing with arbitration shall be governed exclusively by the
United States (Federal) Arbitration Act, 9 U.S.C. Sections 1-16, and judgment
on or enforcement of the award or any direction for specific performance
rendered by the arbitrators may be entered by any court having jurisdiction
thereof or having jurisdiction over the relevant party or assets of such
party.

         (i) If, notwithstanding the parties' agreement to arbitrate, any
issue is presented to a court for decision, the parties hereby waive any
right to trial by jury.



         (j) The parties agree that any dispute between the parties and the
arbitration itself shall be kept confidential and that the existence of the
arbitration and any element of it (including but not limited to any pleading,
brief or other document submitted or exchanged, any testimony or other oral
submission, and any award) shall not be disclosed except to the
arbitrator(s), the CPR Institute for Dispute Resolution, the parties, their
counsel and any person necessary to the conduct of the proceeding, except as
may be lawfully required in judicial proceedings relating to the arbitration
or otherwise.

13.      NO PUNITIVE OR EMOTIONAL DAMAGES

The parties hereto agree that neither the Executive nor the Company will be
entitled to seek or obtain punitive, exemplary or similar damages of any kind
from the other or, in the case of Executive, from the Company's officers,
directors, employees or shareholders, or to seek or obtain damages or
compensation for emotional distress, as a result of any dispute, controversy
or claim arising out of, relating to or in connection with this Agreement, or
the performance, breach, termination or validity thereof. Nothing herein
shall preclude an award of compensatory or punitive damages against any other
third party.

14.      INJUNCTIVE RELIEF TO AVOID IRREPARABLE INJURY

         (a) Executive acknowledges and agrees that the individualized
services and capabilities that he will provide to the Company under this
Agreement are of a personal, special, unique, unusual, extraordinary and
intellectual character.

         (b) Executive acknowledges and agrees that because the internet
telephony and web communications industry is globally integrated and that its
constituent companies are dependent for their survival on protection of their
confidential information which is highly advanced and technical and on
carefully developed knowledge of customer systems and requirements, the
restrictions in this agreement are reasonable to protect the Company's rights
under this Agreement and to safeguard the Company's and it Affiliates'
Confidential Information.

         (c) Executive acknowledges and agrees that the covenants and
obligations of Executive with respect to noncompetition, nonsolicitation,
confidentiality and Company property 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 and its Affiliates
irreparable injury for which adequate remedies are not available at law.
Executive therefore agrees that the Company shall be entitled to an order of
specific performance, injunction, restraining order or such other interim or
permanent equitable relief (without the requirement to post bond) restraining
Executive from committing any violation of the covenants and obligations
contained in this Agreement. Executive acknowledges and agrees that if any
one or more of any part of such restrictions shall be rendered or judged
invalid or unenforceable, such restriction or part shall be deemed to be
severed from this Agreement and such invalidity or unenforceability shall not
in any way affect the validity of the remaining provisions.



         (d) These injunctive remedies are cumulative and are in addition to
any other rights and remedies the Company may have at law or in equity.

15.      AUTOMATIC AMENDMENT BY COURT ORDER AND INTERIM ENFORCEMENT

         (a) If the Arbitrator(s) or a court determines that, but for the
provisions of this paragraph, any part of this agreement is illegal, void as
against public policy or otherwise unenforceable, the relevant part will
automatically be amended to the extent necessary to make it sufficiently
narrow in scope, time and geographic area to be legally enforceable. All
other terms will remain in full force and effect.

         (b) If the Executive raises any question as to the enforceability of
any part or terms of this agreement, including, without limitation, the
provisions relating to noncompetition, nonsolicitation, confidentiality and
Company property, the Executive specifically agrees that he will comply fully
with this Agreement unless and until the entry of an arbitral award to the
contrary.

in this Agreement. This Agreement may not be altered, amended or added to
except in a single writing signed by the Company and the Executive.

18.      WAIVER OF BREACH

20.      ARM'S LENGTH

         (a) This Agreement was entered into at arm's length, without duress
or coercion, and is to be interpreted as an agreement between parties of
equal bargaining strength. Both the Company and the Executive agree that this
Agreement is clear and unambiguous as to its terms, and that no parol or
other evidence will be used or admitted to alter or explain the terms of this
Agreement, but that it will be interpreted based on the language within its
four corners in accordance with the purposes for which it is entered into.

         (b) The parties hereto expressly agree that any rule or contractual
interpretation, as applied under California law or anywhere else, that would
allow parol or extrinsic evidence to attempt to show fraud in the inducement
or duress to contradict the plain, unambiguous terms of this Agreement shall
not apply to this Agreement and its performance and enforcement. This
provision is a material part of this Agreement and, should any party try to
introduce evidence



contrary to this provision, any other party shall be entitle to consider it a
breach and to rescind this contract in full.

21.      SUCCESSORS AND ASSIGNS

         (a) This Agreement will inure to the benefit of, and will be binding
upon, the Company, its successors and assigns and upon the Executive and his
heirs, successors and assigns; PROVIDED, HOWEVER, that, because this is an
Agreement for personal services, the Executive cannot assign any of his
obligations under this Agreement to anyone else.

         (b) This Agreement may be executed in counterparts, in which case
each of the two counterparts will be deemed to be an original and the final
counterpart shall be deemed to have been executed in New York, New York.

22.      NEW YORK LAW GOVERNS

validity, interpretation, performance or otherwise, will therefore be
governed by and construed in accordance with the laws of the State of New
York applicable to agreements made and to be wholly performed in New York,
