breach thereof, shall be settled by arbitration administered by the American
Arbitration Association under its Commercial Arbitration Rules in the City of
New York, and judgment on the award rendered by the arbitrator(s) may be entered
in any court having jurisdiction thereof.

The parties acknowledge that any breach of this Agreement to arbitrate may cause
irreparable injury, and accordingly consent to the jurisdiction of the State and
Federal Courts located in the City of New York for any application to compel
specific performance of this Agreement to arbitrate.

In the event that any claim is found not to be arbitrable due to, inter alia, a
statutory policy precluding the arbitration of such claim, the parties consent

Agreement and at BANSI's sole discretion enter into a new Agreement with the new
ownership. Any attempted assignment or delegation in contravention of the above

ineffective to the extent that: (a) Agent shall not have given BANSI at least
thirty (30) days prior written notice of such assignment; or (b) such assignment
attempts to impose upon BANSI obligations to the assignee additional to payments

access. It is agreed that prior notification will be given when access is
required.

22.  SEVERABILITY

In the event that any one or more of the provisions contained herein shall, for
any reason, be held to be unenforceable in any respect, such unenforceability
shall not affect any other provision of this Agreement, but this Agreement shall
then be construed as if such unenforceable provision or provisions never had

relieve Agent of responsibility or liability for the acts or omissions of such
subcontractor in performing Agent's obligations hereunder.

All obligations hereunder incurred by Agent prior to the termination or
expiration of this Agreement shall survive such termination or expiration.

25.  TAXES

                               AMENDMENT NO. 2 TO
                       THE BELL ATLANTIC AUTHORIZED AGENT

                      NETWORK SERVICES MARKETING AGREEMENT

          This Amendment No. 2 to the Bell Atlantic Authorized Agent Network
Services Marketing Agreement ("Agreement") is made this first day of January,
1999, by and between USTeleCenters, a Delaware corporation with principal
offices located at 745 Atlantic Avenue, Boston, MA 02111-2626 (hereinafter
referred to as "Agent"), and Bell Atlantic Network Services, Inc., a Delaware
corporation with principal offices located at 1310 North Court House Road,
Arlington, Virginia 2220l (hereinafter referred to as "BANSI").

          WHEREAS, BANSI and Agent are parties to the Agreement which authorizes
Agent to act as BANSI's non-exclusive agent for the marketing of Telephone
Company Services; and

          WHEREAS, BANSI and Agent intend for Agent to serve as both a
telemarketing agent as well as a premises agent for the states of Delaware, New
Jersey, Maryland, Pennsylvania, Virginia, Washington DC, West Virginia, New
York, New Hampshire, Massachusetts, Maine, Rhode Island and Vermont
("Telemarketing Area");

NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS:

          1. In the Telemarketing Area, Agent is authorized to make sales both
          through telemarketing and customer premises visits. Unless otherwise
          authorized in writing, Agent may not telemarket outside of the
          Telemarketing Area.

          2. When Agent is acting as a telemarketer, Agent shall proactively
          contact Customers over the telephone for purposes of closing a sale
          over the phone.

          3. When Agent is acting as a telemarketer, Agent shall comply with all
          guidelines, rules and principles established by BANSI, including,
          without limitation, the following:

          (a) Agent shall have the capability and all necessary equipment to
          provide, and shall provide, in-house and remote telephone monitoring
          (as specified by BANSI) of sales and marketing calls handled by Agent.
          BANSI shall have the right to monitor any calls remotely or otherwise
          without prior written notice to Agent.

          (b) Agent shall have the necessary technology to block, and shall
          block within forty-eight (48) hours of receiving a Do Not Contact List
          from BANSI, all telephone numbers included on that list which shall
          set forth the names and/or numbers of Customers who are not to be
          contacted by Agent for the marketing and sale of Services.
