         10. Restrictive Covenants

         (a) Confidential Information. During the Agreement Term and at all
times thereafter, the Executive agrees that he will not divulge to anyone (other
than the Company or any persons employed or designated by the Company) any
knowledge or information of a confidential or proprietary nature relating to the
business of the Company or any of its subsidiaries or affiliates, including,
without limitation, all trade secrets (unless readily ascertainable from public
or published information or trade sources) and confidential commercial
information, and the Executive further agrees not to disclose, publish or make
use of any such knowledge or information without the consent of the Company.

         (b) Non-competition. The Executive acknowledges that (i) the Company is
currently engaged in the business of providing high quality, low-cost telephone
calls over the Internet and related products and services ("Internet
Telephony"), (ii) his work for the company will give him access to trade secrets
of and confidential information concerning the Company, and (iii) the agreements
and covenants contained in this Agreement are essential to protect the business
and goodwill of the Company. Accordingly, the Executive covenants and agrees
that during the Restricted Period (defined below), the Executive shall not,
without the prior written consent of the Company, (1) engage or participate in
the business of developing, managing or operating any Internet Telephony
business (a "Competitive Business") on his own behalf or on behalf of any person
or entity, and the Executive shall not acquire a financial interest in any
Competitive Business (except for publicly traded equity interests that do not
exceed five percent (5%) of such class of equity) or (2) directly or indirectly
solicit or encourage any employee of the Company or any of its affiliates to
leave the employment of the Company or any of its affiliates. For purposes
hereof, the "Restricted Period" shall be the Agreement Term (as may be
terminated pursuant to Section 6 hereof) and, except in the event of a
termination described in Section 6(a) hereof, the 12-month period following any
termination of the Executive's employment hereunder.


         (c) Non-disparagement. Executive covenants and agrees that Executive
shall not make or publish any written or oral statements or remarks concerning
the Company including, without limitation, remarks which may be disparaging,
deleterious or damaging to the integrity, reputation or good will of the
Company, its management, board members or employees. Except as may be required
by law or authorized in advance by Company, Executive covenants and agrees that
Executive shall not make or publish any written or oral statements or opinions
regarding Company, including its present and former employees, officers and
directors.

         (d) Enforcement. The Executive acknowledges and agrees that the Company
will have no adequate remedy at law, and could be irreparably harmed, if the
Executive breaches or threatens to breach any of the provisions of Section 10 of
this Agreement. The Executive agrees that the Company shall be entitled to
equitable and/or injunctive relief to prevent any breach or threatened breach of
this Section 10, and to specific performance of each of the terms of this
Section in addition to any other legal or equitable remedies that the Company
may have. The Executive further agrees that he shall not, in any equity
proceeding relating to the enforcement of the terms of this Section 10, raise
the defense that the Company has an adequate remedy at law.

         (a) This Agreement shall be binding upon and shall inure to the benefit
of the Company, its successors and any person or other entity that succeeds to
all or substantially all of the business, assets or property of the Company. To
the extent not otherwise provided by application of law, the Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation, transfer or otherwise) to all or substantially all of the
business, assets or property of the Company, to expressly assume and agree to
perform the obligations of the Company under this Agreement in the same manner
and to the same extent that the Company is required to perform hereunder. As
used in this Agreement, the "Company" shall mean the Company as hereinbefore
defined and any successor to its business, assets or property as aforesaid which
executes and delivers an agreement provided for in this Section 11(a) or which
otherwise becomes bound by all the terms and provisions of this Agreement by
operation of law. Except as provided by the foregoing provisions of this Section
11(a), this Agreement shall not be assignable by the Company without the prior
written consent of the Executive. In the event that this Agreement is assigned
to any person or entity as may be permitted hereunder, the Company shall be
secondarily liable in the event that any such person or entity shall fail to
satisfy its obligations under Section 4, 6 or 7 hereof.

         (b) This Agreement and all rights of the Executive hereunder shall
inure to the benefit of and be enforceable by the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If the Executive should die while any amounts are due and
payable to the Executive hereunder, all such amounts, unless otherwise provided
herein, shall be paid to the Executive's designated beneficiary or, if there is
no such designated beneficiary, to the legal representatives of the Executive's
estate. This Agreement is personal in nature and the obligations of the
Executive hereunder are not be assignable to any person.
