reasonably determined by the Board, and which is not remedied within 30 days
after receipt of written notice from the Company specifying such breach, (ii)
commission by the Executive of an act of fraud upon, or willful misconduct
toward, the Company or any Affiliate (as defined below in this Section 3(b)), as

this purpose) after a hearing by the Board following fourteen days' notice to
the Executive of such hearing, (iii) a material breach by the Executive of
Section 6 or Section 9, (iv) the conviction of the Executive of any felony or

Section 8(c);

               (v)    without limiting the generality of the foregoing, any

shall be communicated by Notice of Termination to the other party hereto given

<PAGE>

Termination (as defined below) is other than the date of receipt of such notice,
specifies the termination date (which date shall not be more than 15 days after
the giving of such notice). The failure by the Executive or the Company to set
forth in the Notice of Termination any fact or circumstance which contributes to
a showing of Good Reason or Cause shall not waive any right of the Executive or
the Company hereunder or preclude the Executive or the Company from asserting
such fact or circumstance in enforcing the Executive's or the Company's rights
hereunder.

          (e)  Date of Termination.  "Date of Termination" means (i) if the
               -------------------    -------------------

               calendar year, based upon the number of days during such calendar
               year prior to the Date of Termination (the "Accrued Bonus"); and

               the Employment Period plus (B) such additional period of time (if
               any) that the Company continues (in its sole discretion) to pay
               the Executive the Annual Base Salary in accordance with its
               customary practices for paying executive salary (but the
               aggregate time under (A) and (B) of this clause (2) shall not
               exceed two years);

                      (3)  termination of employment by the Company as a result
               of it providing a Non-Renewal Notice under Section 1, that period
               of time (if any) following termination and continuing for as long
               as the Company continues (in its sole discretion) to pay the
               Executive the Annual Base Salary in accordance with its customary
               practices for paying executive salary (not to exceed two years);

                      (4)  termination of employment by the Executive for Good
               Reason, the period of time following such termination and

               no event to exceed two years);

                      (5)  termination of employment by the Executive without
               Good Reason, two years following such termination; and

                                       10
<PAGE>

                      (6)  termination of employment by the Executive as a
               result of the Executive providing a Non-Renewal Notice under
               Section 1, one year from the date of termination plus such
               additional period (which additional period may not exceed one
               year) for as long as the Company in its sole discretion pays,
               during any such additional period, the Executive the Annual Base
               Salary in accordance with its customary practices for paying
               executive salary, provided that the Company shall notify the
               Executive of the Company's intention not later than 60 days prior
               to the expiration of the Employment Period if the Company intends
               to pay the Executive as aforesaid during such additional period.

          (d)  The Executive covenants and agrees that until the expiration of
his covenants set out in Sections 9(a) and (b), he shall use his reasonable best
efforts to ensure that any and all current and future opportunities relating to
the telecommunications businesses and electronic commerce business of the
Company and its Affiliates and any businesses ancillary thereto shall be carried
out through the Company and its Affiliates.

          (e)  The foregoing covenants are given by the Executive acknowledging
that he has specific knowledge of the affairs of the Company and its Affiliates.

          (f)  The Executive acknowledges and agrees that the nature of the
Confidential Information to which he will have access during his employment by
the Company or any Affiliate thereof would make it difficult, if not impossible,
for him to perform in a similar capacity for a Competitive Business within the
two year period following his termination for any reason from the Company,
without disclosing or utilizing the Confidential Information and that if he were
to perform in a similar capacity for a Competitive Business it would be
inevitable that he would disclose and/or use Confidential Information.

          (g)  The Executive acknowledges that during and limited only to the
two year period following his termination for any reason from the Company,
violations of the provisions of Section 6 or 9 will cause immediate and
irreparable harm to the Company, entitling the Company to an injunction in or by
a court of competent jurisdiction or arbitration in addition to any other
remedies the Company may have at law or in equity, including recovery of
reasonable attorneys' fees and costs incurred by the Company in enforcing the
provisions of Section 6 or 9. In the event that any covenant contained in
Section 9 or portion of any such covenant should be unenforceable or be declared
invalid for any reason whatsoever, such unenforceability or invalidity shall not
affect the enforceability or validity of the remaining portions of the covenants
and such unenforceable or invalid portions shall be severable from the remainder
of this Agreement. The Executive hereby acknowledges and agrees that, during and
limited only to the two year period following his termination for any reason
from the Company, all restrictions contained in this Section 9 are reasonable
and valid and all defenses to the strict enforcement thereof by the Company and
are hereby waived by him.

                                       11
<PAGE>

          (h)  Nothing in Section 9 shall be deemed to prevent or prohibit the
Executive from making investments in his personal capacity unless such
investments are of a type that may conflict with the efficient performance of
his duties or with any of his obligations to the Company or any Affiliate
thereof; provided further that nothing contained herein shall preclude the
         --------
Executive from purchasing or owning equity interests in any Person engaged in a
Competitive Business whose shares are traded on a recognized stock exchange or
over-the-counter market, so long as the Executive's holdings therein do not
exceed five percent (5%) of the issued and outstanding capital of the Person in
question.

          (i)  The Executive acknowledges and agrees that he has received good
and valuable consideration in exchange for his covenants and obligations under
this Agreement.

     10.  Effect of Agreement on Other Benefits.  The existence of this
          -------------------------------------
Agreement shall not prohibit or restrict the Executive's entitlement to full
participation in the executive compensation, employee benefit and other plans or
programs in which senior executives of the Company are eligible to participate.

     11.  Miscellaneous.
          -------------

          (a)  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF NEW YORK WITHOUT REFERENCE TO PRINCIPLES OF CONFLICT OF LAWS.
The captions of this Agreement are not part of the provisions hereof and shall
have no force or effect.  Whenever the terms "hereof", "hereby", "herein", or
                                              ------    ------    ------

                           -------      ---------
referring to the indicated section or paragraph of this Agreement unless the
context indicates to the contrary.  The use of the term "including" herein shall
                                                         ---------

                         ----------------------------
be amended or modified otherwise than by a written agreement executed by the
parties hereto or their respective successors and legal representatives.

                              St. David's DD BX

or to such other address as either party shall have furnished to the other in
writing in accordance herewith.  Notices and communications shall be effective
when actually received by the addressee.

          (c)  If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws effective during the term of this
Agreement, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a portion of this Agreement; and the remaining provisions of
this Agreement shall remain in full force and effect and shall not be affected
by the illegal, invalid or unenforceable provision or by its severance from this
Agreement.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision there shall be added automatically as part of this Agreement a
provision as similar in terms and scope to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable.

          (d)  The Company shall obtain and maintain a director's and officer's
liability insurance policy during the term of the Executive's employment
covering the Executive on commercially reasonable terms, and the amount of
coverage shall be reasonable in relation to the Executive's position and
responsibilities hereunder; provided, however, that such coverage may be reduced
                            --------  -------
or eliminated to the extent that the Company reduces or eliminates coverage for
its directors and executives generally.

          (e)  The Company may withhold from any amounts payable under this
Agreement such federal, state or local taxes as shall be required to be withheld
pursuant to any applicable law or regulation.

          (f)  The Executive's or the Company's failure to insist upon strict
compliance with any provision of this Agreement or the failure to assert any
right the Executive or the Company may have hereunder, shall not be deemed to be
a waiver of such provision or right or any other provision or right of this
Agreement.

          (g)  The Executive acknowledges that money damages would be both
incalculable and an insufficient remedy for a breach of Section 6 or 9 by the
Executive and that any such breach would cause the Company irreparable harm.
Accordingly, the Company, in addition to any other remedies at law or in equity
it may have, and shall be entitled, without the requirement of posting of bond
or other security, to equitable relief, including injunctive relief and specific
performance, in connection with a breach of Section 6 or 9 by the Executive.
The Company shall be entitled to obtain such remedies from any court of
competent jurisdiction on a provisional basis pending the resolution of

                                       13
<PAGE>

a Dispute involving an alleged breach of Section 6 or 9, and without first
obtaining a provisional award authorizing such remedies from an arbitral panel.

          (h)  The provisions of this Agreement constitute the complete
understanding and agreement between the parties with respect to the subject
matter hereof.

          (i)  This Agreement may be executed in two or more counterparts.

          (j)  (i)    The Executive and the Company shall endeavor initially to
resolve amicably any dispute, difference, claim, or controversy arising out of
or relating to this Agreement, or the breach thereof (a "Dispute") first by
                                                         -------
negotiation.  The party claiming the existence of a Dispute shall provide
written notice to the other party specifying the nature and basis of the
Dispute.  In the event that no agreement is reached within 30 days after notice
of the existence of a Dispute has been provided, either party shall have the
right to have such Dispute determined by arbitration as provided in this Section
11(j).

               (ii)   Any and all Disputes that are not resolved through
negotiation as set forth above shall be finally settled in a binding arbitration
administered by the American Arbitration Association under its Commercial
Arbitration Rules then in effect. The place of arbitration shall be New York,
New York. If the parties are unable to agree on the appointment of a single
arbitrator to conduct the arbitration within 20 days after the claimant has
filed its demand for arbitration, then the arbitration shall be conducted by a
panel of three arbitrators, appointed as follows: The Company and the Executive
each shall appoint one arbitrator, and the two arbitrators so appointed shall
appoint the third arbitrator, who shall chair the panel. No arbitrator may be
affiliated, associated, or related to the Company, any Affiliate, employee or
executive of the Company, or the Executive in any manner whatsoever.

               (iii)  The award of the arbitrators shall be final and binding,
and judgment upon any such award may be entered by any court of competent
jurisdiction. The arbitrators shall have no authority to award damages in excess
of compensatory damages, and each party hereby irrevocably waives any right to
recover such non-compensatory damages (including exemplary damages, treble
damages, and any other penalty or type of punitive damages) with respect to any
Dispute arising hereunder. Each party shall bear such party's own expenses
related to any arbitration, but the parties shall share equally the expenses of
the arbitration tribunal and the AAA.

          (k)  This Section 11 and Sections 4, 5, 6, 7 and 9 of this Agreement
shall survive the termination of this Agreement and termination of this
Agreement shall not release any party hereto from any liability arising out of
its breach of this Agreement prior to termination.

          (l)  The Executive represents and warrants to the Company that, to the
best of his personal knowledge and belief, neither the execution and delivery of
this

                                       14
<PAGE>

Agreement, his commencement of employment hereunder nor the performance of his
duties hereunder conflicts with any contractual commitment on his part owed to
any third party or violates or interferes with any rights of any third party. In
this regard, the Company has been provided a copy of the relevant provisions of
the Executive's agreement with AT&T dated September 1, 1999.

          (m)  The Company shall have the right to secure, in its own name or
otherwise, and at its own expense, life, disability, accident or other insurance
covering the Executive and the Executive shall have no right, title or interest
in or to such insurance. The Executive shall assist the Company in procuring
such insurance by submitting to reasonable examinations and signing such
applications and other instruments as may be required by the insurance carriers
to which applications is made for any such insurance.

          (n)  At the request of the Company, the Executive shall execute the
necessary documents to become a party to (i) the Amended and Restated
Securityholders' Agreement dated July 14, 1999, by and among the Company and
various other parties including various shareholders of the Company (the "SHA")
                                                                          ---
and (ii) the Registration Rights Agreement referred to therein.

          (o)  The Executive represents and warrants to the Company that he does
not hold any interest in any of the following New Investors (as that term is
defined in the Amended and Restated Securityholders' Agreement referred to in
the SHA):  Boston Ventures Limited Partnership V, L.P., Kelso Investment
Associates VI, L.P., KEP VI, L.L.C., Providence Equity Partners III L.P.,
Providence Equity Operating Partners III L.P., Spectrum Equity Investor III,
