         WHEREAS, the Company will offer local exchange services ("Service(s)")

         WHEREAS, the Customer is a reseller operating in the Commonwealth of
Massachusetts,;

         WHEREAS, the Company and the Customer have negotiated in good faith for

Telecommunications Act of 1996.

         NOW, THEREFORE, in consideration of the mutual obligations set forth
herein, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the Company and the Customer agree
as follows:

1.       RESALE ARRANGEMENT

         The Company will offer telecommunications services it provides at
 retail to end users in the Commonwealth of Massachusetts for resale by the
 Customer in accordance with the attached Terms and Conditions -- Resale
 Services ("Terms and Conditions") contained in Attachment A. Attachment A is
 incorporated herein as an integral and necessary part of the parties agreement.
 Whenever reference is made herein to the Agreement, the reference includes
 Attachment A.

2.       TERM OF AGREEMENT

      A. The Company will file the Agreement promptly following its execution
         with the Department for approval pursuant to section 252 of the
         Telecommunications Act of 1996. The Agreement will be effective in
         accordance with the Department's order or decision which approves the
         Agreement.

      B. Upon execution of the Agreement by both parties, the Company and
         Customer shall endeavor to jointly develop an implementation plan for
         the services that Customer will resell.

      C. Each Party agrees to fully support approval of the Agreement by
         the  Department without modification. The Parties, however, reserve
         the right to  seek regulatory relief and otherwise seek redress
         from each other regarding  performance and implementation of this
         Agreement. In the event the Department  rejects this

                                       1
<PAGE>

         Agreement in whole or in part, the Parties agree to meet and
         negotiate in good faith to arrive at a mutually acceptable modification
         of the rejected portion(s); provided that such rejected portion(s)
         shall not affect the validity of the Remainder of this Agreement.

     D. The Agreement is subject to change, modification, or
        cancellation as may be  required and mutually agreed by a either
        Party based on any significant change  in Federal Communications
        Commission or Department rules which may impact the  provision of
        service under this Agreement or the rights and obligations of the
        Parties under the Act. Either Party may terminate this Agreement
        with 90 days  written notice to the other Party.

3.     CHARGES

       The Customer shall pay the Company the charges contained in
       Attachment A. The Parties understand that the charges contained in
       Attachment A are interim charges subject to revision by the
       Department. If the Department issues any decision or order which
       approves for any telecommunications carrier different charges for
       any of the services contained in Attachment A within six months
       following the effective date of this Agreement, the Parties will
       true-up the charges paid under this Agreement retroactive to the
       effective date of the Agreement based upon the decision or order of
       the Department. However, if the Department does not issue such a
       decision or order within six months, the Parties agree that there
       will be no true-up, and any new charges approved thereafter by the
       Department will apply to the services provided under this Agreement
       as of the date of the Department order or decision.

4.     PROMOTIONAL MATERIAL

       The Company shall provide the Customer with a reasonable amount
       of information related to the use of the services it will resell for
       Customer's use in its marketing and product materials. The Company, in
       consultation with Customer, shall determine the type, quantity, and
       availability of the information to be provided to Customer. The Company
       shall also make available to Customer's personnel basic training related
       to the use and operation of the services. The Company shall reasonably
       determine the timing and content of such training. Such training and
       promotional material shall be provided to the Customer only and the
       Company is under no obligation to provide any training or promotional
       material to any other person or entity the Customer may engage in the
       sale, provision, or use of the Services.

5.     GOVERNING LAW

       This Agreement shall be governed by and construed in accordance with
       the laws of the Commonwealth of Massachusetts, except a provision of law
       which would refer any issue to another jurisdiction.

6.     ENTIRE AGREEMENT

       This Agreement constitutes the entire understanding between the Parties
       with respect to the subject matter hereof and supersedes all prior
       understandings, oral or written representations, statements,
       negotiations, proposals and undertakings in oral written form.

7.     AMENDMENTS AND WAIVERS

       A.    This Agreement may be amended or additional provisions may be
             added by written agreement signed by or on behalf of both parties.
             No amendment or waiver of any provisions of this Agreement, and no
             consent to any default under this Agreement, shall be effective
             unless the same shall be in writing and signed by a duly authorized
             representative on behalf of the party against whom such amendment,
             waiver or consent is claimed, except as otherwise provided in this
             Agreement preceding. In addition, no course of dealing or failure
             of any party to enforce strictly any term, right or condition of
             this Agreement shall be construed as a waiver of such term, right
             or condition.

       B     Either party's failure at any time to enforce any of the
             provisions of this Agreement or any right with respect thereto, or
             to exercise any option herein provided, will in no way be construed
             to be a waiver of such provisions, rights, or options or in any way
             to affect the validity of this Agreement. The exercise by either
             party of any rights or options under the terms herein shall not
             preclude or prejudice the exercise thereafter of the same or other
             rights under this Agreement.

       or  otherwise) this Agreement (or any rights or obligations hereunder)

       which consent shall  not be unreasonably withheld; provided, however,
       each party may assign this  Agreement to a corporate affiliate or an
       entity under its common control or an  entity acquiring all or
       substantially all of its assets or equity by providing  prior written
       notice to the other party of such assignment or transfer. Any  attempted
       assignment or transfer that is not permitted shall be void AB INITIO.
       All obligations and duties of any party shall be binding on all
       successors in  interest and assigns of such party.

                                       4
<PAGE>

        terrorist acts, riots, insurrections, fires, explosions, earthquakes,
        nuclear accidents, floods, strikes, power blackouts, volcanic action,

        or transportation facilities, or acts or omissions of transportation
        common carriers or other causes beyond the control of the party
        obligated to perform. If any force majeure condition occurs, the party
        delayed or unable to perform shall give immediate notice to the other
        Party and shall take all reasonable steps to correct the force majeure

        Notwithstanding any other provision of this Agreement, this Agreement
        is subject to change, modification, or cancellation as may be required
        by a regulatory authority or court in the exercise of its lawful
        jurisdiction.

13.     COMPLIANCE

        Each Party shall comply with all applicable federal, state, and local
        laws, rules, and regulations applicable to its performance under this

        other's name without the written permission of the other in connection
        with promotional, advertising or other marketing material.

16.     SEVERABILITY

        In the event any of the provisions of this Agreement are found
        to be invalid by any administrative agency, arbitrator or court or
        competent jurisdiction, the remaining provisions of this Agreement,
        whether relating to similar or dissimilar subjects, shall nevertheless
        be binding with the same effect as though the invalid provisions were
        deleted, unless the result would be to substantially change the rights
        or obligations of either party, in which event the parties shall seek to
        negotiate in good faith revisions to the Agreement consistent with their
        earlier intent. Failing further agreement, this Agreement shall
        terminate and no party shall be liable to the other, except for

        This Agreement may be executed in any number of counterparts, each of
        which shall be an original, but such counterparts shall together

6.1 TERMS AND CONDITIONS INFORMATION

6.1.1  General

       6.1.1.1   Terms and Conditions Structure

                 A. The terms and conditions are divided into sections which
                    are structured numerically, (e.g., Section 6.1, 6.2, 6.3
                    etc.).

6.1.2  Referencing

       6.1.2.1 Reference to Terms and Conditions

               A. Whenever reference is made in these terms and conditions to
                  tariffs of the Telephone Company, the reference is to the
                  tariffs in force as of the effective date of these terms and
                  conditions, and to amendments thereto and successive issues
                  thereof. The regulations, rates and charges contained herein
                  are in addition to the applicable regulations, rates and
                  charges specified in tariffs of the Telephone Company which
                  may be referenced. To the extent that sections of referenced
                  tariffs violate the Telecommunications Act of 1996 or other
                  FCC regulations, they are void and not applicable under these
                  terms and conditions.

               B. Upon completion of the investigation of these generally
                  available terms and conditions, the Telephone Company will, in
                  compliance with the Department's Order, file resale tariffs,
                  which when approved by the Department, will supersede these
                  terms and conditions.

       6.1.2.2 Trademarks and Service Marks

               A. Refer to D.P.U. Mass. No. 10.

             these terms and conditions are as defined in D.P.U. Mass. No. 10.

       6.1.3.1 Definitions

               END USER - Any person purchasing service for their own use
               rather than for sale to another person, party or entity etc.

               PREMISES - This term as defined in D.P.U. Mass. No. 10 is a
               reference to the premises at which the service is provided, and
               not a reference to the reseller's premises.

                                                         8

<PAGE>

               RESALE - The sale to another person of telecommunications
               services purchased from the Telephone Company. A person purchases
               for resale when such a person purchases a service for the purpose
               of reselling it to another (rather than the purpose of using the
               service itself).

               RESELLER/CUSTOMER - Any individual, partnership, association,
               joint stock company, trust, corporation, governmental entity or
               other entity which subscribes to the telecommunications services
               offered under these terms and conditions.

               TELEPHONE COMPANY - The New England Telephone and Telegraph
               Company.

6.2    GENERAL REGULATIONS

       In addition to the general regulations contained herein, the general
       regulations specified in D.P.U. Mass. No. 10 also apply.

6.2.1  Application of Terms and Conditions

       6.2.1.1  Scope

                A. Regulations, rates and charges in these terms and
                   conditions apply to the offering of Telephone Company
                   telecommunications services for resale.

                B. Only a carrier authorized by law to resell
                   telecommunications services in the Commonwealth of
                   Massachusetts may purchase under these terms and
                   conditions. These terms and conditions are not intended to
                   enlarge, restrict, or otherwise affect any provision of
                   law relating to the authority to resell telecommunications
                   services.

                   1. Resellers do not surrender any right to purchase from
                   any of the Telephone Company's intrastate tariffs by
                   purchasing from these terms and conditions. However, the
                   discounts contained herein will apply only to purchases
                   from these terms and conditions. Resellers purchasing
                   services from the Telephone Company's intrastate tariffs
                   will do so through traditional retail channels.

                C. In addition to the responsibilities and obligations
                   specified in D.P.U. Mass No. 10, the reseller must conform
                   to any applicable rules and regulations set forth by the
                   Department of Public Utilities.

                D. The resale of telecommunications services and the
                   provision thereof by the Telephone Company as set forth in
                   these terms and conditions does not constitute a joint
                   undertaking nor does it constitute an agency, contractual
                   or any other type of relationship between the reseller and
                   the Telephone Company (other than that of purchaser and
                   seller) or between the Telephone Company and the
                   reseller's end user.

                E. A reseller ordering a resold service under these terms and
                   conditions has all of the obligations that would be
                   imposed under the applicable Telephone Company tariff upon
                   an end user who orders the service directly from the
                   Telephone Company. Such obligations include, without
                   limitation, the obligation to pay for the service, whether
                   or not the reseller is being paid by its own customers.
                   The rate charged for such service, when sold to a reseller

                                       9

<PAGE>

                   under these terms and conditions is to be determined in
                   accordance with rates and charges specified in these terms
                   and conditions.

6.2.2 Responsibility of the Telephone Company

      6.2.2.1 Provision of Service

                A. The Telephone Company's obligation to furnish service, or
                   to continue to' furnish service, is dependent on its
                   ability to obtain without charge, danger or undue
                   difficulty access to the premises where the service is to
                   be provided.

                   1. Should a reseller's end user request that a Telephone
                   Company technician prove his/her identity as an employee
                   of the Telephone Company before the end user will permit
                   access to their premises, the technician's Telephone
                   Company identification badge or the NYNEX registered
                   trademark/servicemark (logo) that is visibly displayed on
                   the technician's service vehicle will be evidence of such
                   proof. If the Telephone Company misses the scheduled
                   service appointment as a result of the reseller's end
                   user's refusal to permit access to the Telephone Company
                   technician, neither the reseller nor the reseller's end
                   user will be entitled to any waivers of charges for
                   missed service appointments that may be offered by the
                   Telephone Company under service guarantee programs that
                   are associated with the service being provided.

                B. The Telephone Company reserves the right to refuse an
                   application for service made by, or for the benefit of, a
                   reseller who is indebted to the Telephone Company for
                   telephone service previously furnished.

                   1. In the event that service is connected for a reseller
                   who is indebted to the Telephone Company for service
                   previously furnished to such reseller, the Telephone
                   Company will notify the reseller in writing via Certified
                   U.S. Mail, that the service will be terminated by the
                   Telephone Company unless the reseller satisfies the
                   indebtedness within 10 days of the date of the reseller's
                   receipt of such notification.

                C. The services offered under the provisions of these terms
                   and conditions are subject to the availability of
                   facilities, including switching capacity, and necessary
                   operational support systems.

                   1. If existing facilities will not enable the Telephone
                   Company to meet all outstanding service orders, such
                   orders will be handled in accordance with reasonable
                   priority rules that do not discriminate between resellers
                   purchasing under these terms and conditions and end user
                   customers of the Telephone Company.

                D. Resold services offered by the Telephone Company are at
                   least technically equivalent to the corresponding service
                   offerings that the Telephone Company provides to its own
                   end users provided that the reseller complies with the
                   regulations contained in these terms and conditions.

                E. The Telephone Company will provide service (including the
                   installation and repair thereof) to resellers at standards
                   that meet the capabilities, functions and performance
                   standards available to Telephone Company similarly
                   situated end

                                       10

                   users providing that the reseller complies with the
                   regulations contained in these terms and conditions.

                   1. Telephone Company personnel dispatched to a reseller's
                   end user premises for purposes of installation or repair
                   will not accept requests for new or modified service
                   beyond that requested by the reseller.

      6.2.2.2 Interruption of Service

                A. Allowances for interruption of service are available to
                   resellers to the extent and under the same circumstances
                   as they would be available to Telephone Company end users
                   under D.P.U. Mass. No. 10.

6.2.3 Responsibility of the Reseller

      6.2.3.1 Reseller Notification and Coordination

                A. Unless otherwise specified herein, whenever customer
                   notification is required, the Telephone Company is
                   responsible for providing notice only to the reseller who
                   is the customer of record.

                   1. The reseller, and not the Telephone Company is
                   responsible for providing any notices, bill inserts or
                   other information as may be required to the reseller's end
                   users.

      6.2.3.2 Liability

                A. The reseller shall reimburse the Telephone Company for
                   damages to Telephone Company facilities utilized to
                   provide services under these terms and conditions caused
                   by negligence or willful act of the reseller or the
                   reseller's end user or resulting from the reseller's or
                   reseller's end user's improper use of the Telephone
                   Company facilities, or due to malfunction of any
                   facilities or equipment provided by other than the
                   Telephone Company. Nothing in the foregoing provision
                   shall be interpreted to hold one reseller liable for
                   another reseller's actions. The Telephone Company will,
                   upon reimbursement for damages, cooperate with the
                   reseller in prosecuting a claim against the person causing
                   such damage and the reseller shall be subrogated to the
                   right of recovery by the Telephone Company for the damages
                   to the extent of such payment.

                B. With respect to claims of patent infringement made by
                   third persons, the reseller shall defend, indemnify,
                   protect and save harmless the Telephone Company from and
                   against all claims arising out of the combining with, or
                   use in connection with, the services provided under these
                   terms and conditions, any circuit, apparatus, system or
                   method provided by the reseller or reseller's end user.

                C. The reseller shall defend, indemnify and save harmless the
                   Telephone Company from and against suits, claims, losses
                   or damages including punitive damages, attorney's fees and
                   court cost by third persons arising out of the
                   construction, installation, operation, maintenance or
                   removal of the circuits, facilities or equipment connected
                   to the Telephone Company's services provided under these
                   terms and conditions, including, without limitation,
                   Workmen's Compensation claims, actions for infringement of
                   copyright and /

                                      11

<PAGE>

                   or unauthorized use of program material, libel and slander
                   actions based on the content of communications transmitted
                   over the reseller's circuits, facilities or equipment, and
                   proceedings to recover taxes, fines, or penalties for
                   failure of the reseller to obtain or maintain in effect
                   any necessary certificates, permits, licenses, or other
                   authority to acquire or operate the services provided
                   under these terms and conditions; provided, however, the
                   foregoing indemnification shall not apply to suits,
                   claims, and demands to recover damages for damage to
                   property, death or personal injury unless such suits,
                   claims or demands are based on the tortious conduct of the
                   reseller, its officers, agents or employees.

                D. The reseller shall defend, indemnify and save harmless the
                   Telephone Company from and against any suits, claims,
                   losses or damages, including punitive damages, attorneys
                   fees and court costs by the customer or third parties
                   arising out of any act or omission of the reseller or the
                   reseller's end user in the course of using services
                   provided under these terms and conditions.

                E. In case of damage, loss, theft or destruction of equipment
                   and facilities furnished by the Telephone Company due to
                   negligence or willful act of the reseller or the
                   reseller's end user or other persons authorized to use the
                   service, the reseller or reseller's end user may be
                   required to pay the expense incurred by the Telephone
                   Company to replace or restore the equipment and facilities
                   to its original condition.

                F. The reseller assumes the responsibility for enforcement of
                   all tariff regulations and class of service restrictions
                   imposed for any particular service (e.g. prohibitions
                   against unlawful use, damage to Telephone Company
                   property, distinctions between residence and business) and
                   any liability arising from violations thereof.

      6.2.3.3   Certifications and Proof of Exemptions

                A. Upon reasonable request the reseller shall certify to the
                   Telephone Company in writing that the services the
                   reseller is purchasing under these terms and conditions
                   are being purchased for resale.

                B. The reseller shall provide the Telephone Company with any
                   certificates or other documentation that may be required
                   under state law pertaining to tax exemptions.

      6.2.3.4   References to the Telephone Company

                A. The reseller may advise end users that certain services
                   are provided by the Telephone Company in connection with
                   the service the reseller furnishes to end users; however,
                   the reseller shall not state, imply or represent that the
                   Telephone Company jointly participates in or is part of
                   any partnership or joint business arrangement for the
                   provision of services to the reseller's customers.

6.2.4 Customer Notification and Coordination

      6.2.4.1   Provision and Ownership of Telephone Numbers

                A. The Telephone Company reserves the reasonable right to
                   assign, designate or change telephone numbers, or any
                   other call number designations associated

                                       12

<PAGE>

                   with resold service, or the Telephone Company serving
                   central office prefixes associated with such numbers, when
                   necessary in the conduct of business.

                B. Should it become necessary to make a change in such
                   number(s), the Telephone Company will give the reseller
                   six months notice of the change(s), including an
                   explanation of the reason(s) for the change(s), by
                   Certified U.S. Mail.

                   1. In the case of emergency conditions, (e.g. a fire in a
                   wire center), it may be necessary to change a telephone
                   number without six months notice in order to provide
                   service to the reseller.

6.3   ORDERING OF SERVICE

6.3.1 Orders for Resold Services

      6.3.1.1   General

                A. The reseller shall supply all the information reasonably
                   necessary for the Telephone Company to provide and bill
                   for the requested service, to include the reseller's
                   customer in its directory listing service and to otherwise
                   fulfill its obligations under these terms and conditions
                   [e.g., customer name and premises location, configuration of
                   service, and facility interface].

                   1. The reseller is responsible to submit complete and
                   accurate orders. Failure to do so may result in service
                   discrepancies for which the Telephone Company will not be
                   responsible.

                B. If the reseller assumes the account of an existing
                   Telephone Company end user at the end user's existing
                   premises, the order must identify the end user's billing
                   telephone number and line(s) and indicate that the end
                   user's existing service (or any specified modification to
                   and/or cancellation of the existing service) is to be
                   transferred to the reseller.

                   1. Authorization to Assume an Account - A reseller placing
                   an order under which it will assume the account of an
                   existing Telephone Company end user customer, or the
                   account of an existing end user customer of another
                   reseller, must obtain appropriate authorization from that
                   end user for the change of service provider. The reseller
                   must verify and confirm that authorization is in
                   accordance with the laws and provisions that govern such
                   matters as established or may be established in the
                   Commonwealth of Massachusetts.

                C. Resellers may not order services in a particular building
                   or other location where a reseller has not yet obtained
                   end user customers at the time that the reseller's order
                   is placed with the Telephone Company.

                D. Resellers may not order service in a particular building
                   or other location when doing so would preclude or delay
                   other potential providers from offering services in that
                   particular building or other location.

                E. Resellers may not order service under these terms and
                   conditions without a reasonable basis for believing that
                   such services will actually be needed by the reseller to
                   meet anticipated demand.

                                       13

<PAGE>

                F. The Telephone Company will not process any orders,
                   complaints or other requests received from the reseller's
                   end user.

                G. Primary Interchange Carrier (PIC) Changes-The Telephone
                   Company will only accept an order to change the PIC,
                   whether interLATA or intraLATA, for a resold Telephone
                   Company exchange service line from the reseller. The
                   Telephone Company will only accept an order to freeze the
                   PIC from the reseller. The reseller will be responsible
                   for all PIC change charges.

                H. If the order is for modification or discontinuance of
                   service, the order shall identify the billing telephone
                   number and telephone number of the service and the changes
                   desired, and any additional information required by the
                   Telephone Company.

      6.3.1.2   Automated Order Interface

                A. Orders for resold services and modifications to or
                   cancellation of an existing order must be placed by the
                   reseller with the Telephone Company through the
                   appropriate automated interface established by the
                   Telephone Company. Such interface will facilitate the
                   following order processes.

                   1. Establishment of end user accounts

                   2. Assignment of telephone numbers

                   3. Entry of service orders into Telephone Company systems

                   4. Installation scheduling and negotiation with end users

                   5. Reservation of installation appointments

                   6. Entry of end user service and repair inquiries

                   7. Verification of the network status of an associated
                   telephone line in conjunction with Telephone Company systems

                   8. Other processes that would facilitate the processing of
                   the reseller's order.

                B. The Telephone Company will establish automated interface
                   specifications (e.g. formats) for data, delivery
                   (transport) and network descriptions, etc.

                   1. Resellers must comply with methods, procedures and
                   operational guidelines in utilizing the interface
                   specifications established by the Telephone Company.

                   2. Any use of the interface(s) by the reseller or any
                   other party for unauthorized purposes (e.g., access to
                   data or to enter false information) will be considered
                   abuse or fraudulent use of the interface and is
                   prohibited. Such action may result in the Telephone
                   Company terminating the resellers use of the interface.

                D. If the Telephone Company determines or suspects that abuse
                   or fraudulent use of the interface has occurred, the
                   Telephone Company will, as required by law, refer the
                   matter to the appropriate law enforcement agency.

        6.3.1.3 Disclosure of Reseller Information

                A. Telephone Company personnel primarily involved in the
                   marketing of services to end user customers or other
                   resellers will not have access to order information
                   provided by the reseller to the Telephone Company except
                   under the following situations.

                   1. The Telephone Company will disclose to any local
                   exchange carrier the fact that a given end user who was
                   previously a customer of such carrier is no longer one of
                   the carriers customers.

                   2. In order for the Telephone Company to be able to
                   conduct its business, the Telephone Company will access
                   service information in order to aggregate data relating to
                   its sale of resold services to resellers.

                   3. Where a reseller's customer consents to and authorizes
                   the disclosure of information related to the customer's
                   order, the Telephone Company may disclose such data to
                   Telephone Company retail marketing personnel or to other
                   resellers.

                   4. If a Telephone Company end user subsequently becomes an
                   end user of a reseller, the Telephone Company will,
                   without the consent and authorization of the end user
                   customer, provide the reseller with all information
                   necessary to enable it to assume the end users account
                   including the customer's service configuration and billing
                   name and address.

                   5. The Telephone Company will disclose, without the
                   consent and authorization of the reseller's end user
                   customer, information pursuant to industry-wide
                   arrangements for the exchange of information on end users
                   credit histories, consistent with applicable legal
                   requirements.

                B. Section 6.3.1.3A shall not prohibit attempts to sell
                   Telephone Company telecommunications services by Telephone
                   Company employees who have access to information relating
                   to specific orders placed by resellers under these terms
                   and conditions, so long as:

                   1. The employee spends a de-minimus amount of his or her
                   time involved in the marketing of Telephone Company
                   telecommunications services, and

                   2. The employee does not utilize the reseller information
                   in such sales.

                C. In the case of a reseller's end user who requests a change
                   from their present reseller to the Telephone Company or to
                   another reseller, the Telephone Company will disclose the
                   information necessary to enable the Telephone Company or
                   other resellers to assume the account. Such information
                   includes the customer's service configuration, billing name
                   and address.

                D. The Telephone Company will disclose the identity of the
                   reseller providing service to an end user for the purposes
                   of Telephone Company marketing personnel who are
                   responding to a question from an end user about the
                   identity of their service provider.

        6.3.1.4 Evidence of End User Consent and Authorization

                                      15

<PAGE>

                A. Where the Telephone Company identifies that end user
                   consent is required for the disclosure of information, the
                   Telephone Company will obtain consent and authorization in
                   writing from the end user.

        6.3.1.5 Additional Engineering and Special Construction

                A. Additional charges will be applied to an order for service
                   when the Telephone Company determines additional
                   engineering or special construction is necessary to
                   accommodate a reseller request.

                   1. When it is required, the reseller will be so notified
                   and will be furnished with a written statement setting
                   forth the justification for the additional engineering
                   and/or special construction as well as an estimate of the
                   charges in conjunction with the terms and conditions
                   specified in D.P.U. Mass. No. 10.

6.3.2 Responsibility of the Telephone Company

      6.3.2.1   Refusal and Discontinuance of Service

                A. If the reseller fails to comply with the rules and
                   regulations of these terms and conditions, including any
                   payments to be made by it on the dates and times herein
                   specified, the Telephone Company may, on 30 days written
                   notice by Certified U.S. Mail to the reseller refuse
                   additional applications for service and/or refuse to
                   complete any pending orders for service at any time
                   thereafter. If the Telephone Company does not refuse
                   additional applications for service on the date specified
                   in the 30 days notice, and the reseller's noncompliance
                   continues, nothing contained herein shall preclude the
                   Telephone Company from refusing additional applications
                   for service without further notice.

                B. If the reseller fails to comply with the rules and
                   regulations of these terms and conditions, including any
                   payments to be made by it on the dates and times herein
                   specified, the Telephone Company may, on 30 days written
                   notice by Certified U.S. Mail to the reseller, discontinue
                   the provision of the services involved at any time
                   thereafter. In the case of such discontinuance, all
                   applicable charges, including termination charges, shall
                   become due. If the Telephone Company does not discontinue
                   the provision of the services involved on the date
                   specified in the 30 days notice, and the reseller's
                   noncompliance continues, nothing contained herein shall
                   preclude the Telephone Company from discontinuing the
                   provision of the services involved without further notice.

6.3.3 Responsibility of the Reseller

      6.3.3.1   Point of Contact for End Users

                A. The reseller shall serve as the single point of contact
                   for its customers on such matters as billing, requests for
                   new service, requests for the modification or
                   discontinuance of existing services, service trouble
                   reports, repair requests, complaints. etc. The reseller
                   shall be obligated to transmit such requests or

                                      16

<PAGE>

                   reports to the Telephone Company through the automated
                   order interface to the extent reasonably necessary to
                   enable the Telephone Company to fulfill its obligations
                   under these terms and conditions.

      6.3.3.2   Forecasting of Service Requirements

                A. To the extent reasonably necessary for the planning of
                   Telephone Company facilities, the reseller shall provide,
                   upon request of the Telephone Company, forecasts of the
                   approximate number of units of exchange and other services
                   that the reseller expects to require in specific
                   geographic areas. Such forecasts are considered by the
                   Telephone Company as confidential information of the
                   reseller and will be treated in accordance with the
                   provisions specified in these terms and conditions for
                   confidential reseller information.

      6.3.3.3   Refusal, Discontinuance or Transfer of Service

                A. Where a reseller discontinues its provision of service to
                   all or substantially all of its customers, whether by its
                   own decision, as a result of involuntary bankruptcy or for
                   any other reason, the reseller must send advance written
                   notice of such discontinuance to the Telephone Company and
                   to each of the reseller's end users. If service to the
                   reseller is discontinued by the Telephone Company, the
                   reseller must send written notice to each of its end users.

                   1. Such notice must advise the end users that unless they
                   take action to switch to a different carrier with 15 days,
                   provision of their service will be transferred to the
                   Telephone Company. Where the end user elects a specific
                   carrier within the 15 day period, the relevant charges
                   associated with the change shall be paid by that carrier.

                   (a). Should the end user's service be transferred to the
                   Telephone Company, the Telephone Company will provide
                   service to the end users at D.P.U. Mass. No. 10 rates, and
                   not the rates specified in these terms and conditions.
                   Where the end user does not elect a specific carrier
                   within the 15 day period, and as a result is transferred
                   to the Telephone Company, the reseller shall pay the
                   relevant charges associated with the change.

                B. The reseller must provide the Telephone Company with any
                   information necessary to enable the Telephone Company to
                   assume the end users' accounts, including the end users'
                   service configurations and billing names and addresses.

<PAGE>

                   2. Regardless of whether the reseller's end user is still
                   using service, the reseller is responsible for charges
                   incurred by the end user or reseller for all services on a
                   line until the reseller submits an order to discontinue
                   such service.

        6.4.1.2 Billing Convention Methods

                A. The Telephone Company shall bill all charges incurred by
                   and credits due to the reseller under these terms and
                   conditions attributable to services established or
                   discontinued or provided during the preceding billing
                   period.

        6.4.1.3 Billing Periods

                A. The billing date of a bill for a reseller for service
                   provided under these terms and conditions is referred to

                   as follows.

                   1. The Telephone Company will establish a bill day each month
                   for each reseller account.

                   2. The bill will cover all non-usage sensitive service
                   charges and usage charges for the period beginning with
                   the day following the last bill day and extends up to and
                   includes the current bill day. Any known unbilled
                   non-usage charges for prior periods and any known unbilled
                   adjustments will be applied to this bill.

        6.4.1.4 Late Payment Penalty

                A. If any portion of the payment is received by the Telephone
                   Company after the payment date (refer to Section 6.4.1.5),
                   or if any portion of the payment is received by the
                   Telephone Company in funds which are not immediately
                   available to the Telephone Company, then a late payment
                   penalty shall be due to the Telephone Company.

                B. The late payment penalty shall be the portion of the
                   payment not received by the payment date times a late
                   factor. The late factor shall be the lesser of the
                   following.

                   1. The highest interest rate (in decimal value) which may
                   be levied by law for commercial transactions for the
                   number of days from the payment date to and including the
                   date that the reseller actually makes the payment to the

                                      18

<PAGE>

                   2. If such payment date falls on a Sunday or on a legal
                   holiday which is observed on a Monday, the payment date
                   shall be the first non holiday day following such Sunday
                   or legal holiday.

                   3. If such payment date falls on a Saturday or on a legal
                   holiday which is observed on Tuesday, Wednesday, Thursday
                   or Friday, the payment date shall be the last non holiday

        6.4.1.6 Medium of Payment

                A. Bills are payable in immediately available funds.

                   1. Immediately Available Funds denotes a corporate or
                   personal check drawn on a bank account and funds which are
                   available for use by the receiving party on the same day
                   on which they are received and include U.S. Federal
                   Reserve bank wire transfers, U.S. Federal Reserve notes
                   (paper cash), U.S. coins and U.S. Postal Money Orders.

        6.4.1.7 Customer Deposits

                A. The Telephone Company will, in order to safeguard its
                   interests, require a reseller, if the reseller has a
                   proven history of late payments or if the reseller's
                   parent or holding company has a proven history of late
                   payments to the Telephone Company or if the reseller does
                   not have established credit (except for a reseller which
                   is a successor of a company which has established credit
                   and the successor has no history of late payments to the
                   Telephone Company), to make a deposit prior to or at any
                   time after the provision of a service to the reseller to
                   be held by the Telephone Company as a guarantee of the
                   payment of rates and charges.

                B. Such deposit may not exceed the actual or estimated rates
                   and charges for the service for a two month period.

                C. The fact that a deposit has been made in no way relieves
                   the reseller from complying with the Telephone Company's
                   regulations as to the prompt payment of bills.

                D. At such time as the provision of the service to the
                   reseller is terminated, the amount of the deposit will be
                   credited to the reseller's account and any credit balance
                   which may remain will be refunded.

                E. At the option of the Telephone Company, such a deposit
                   will be refunded or credited to the reseller's account
                   when the reseller has established credit or after the
                   reseller has established a one year prompt payment record
                   at any time prior to the termination of the provision of
                   the service to the reseller.

                F. In the case of a cash deposit, the reseller will receive
                   interest as set forth in Section 6.4.1.4 for the period
                   the deposit is held by the Telephone Company. Interest
                   will accrue for the number of days from the date the
                   reseller deposit is received by the Telephone Company to
                   and including the date such deposit is credited to the
                   reseller's account or the date the deposit is refunded by
                   the Telephone Company.

                                      19

<PAGE>

              G. Should a deposit be credited to the reseller account, as
                 indicated above, no interest will accrue on the deposit from
                 the date such deposit is credited to the reseller's account.

      6.4.1.8 Billing Dispute

              In the event that a billing dispute occurs concerning any
              charges billed to the reseller by the Telephone Company, the
              following regulations apply:

              A. The first day of the dispute shall be the date on which the
                 reseller furnishes the Telephone Company with the account
                 number under which the bill has been rendered, the date of the
                 bill and the specific items on the bill being disputed.

              B. The date of resolution shall be the date on which the
                 Telephone Company completes its investigation of the dispute,
                 notifies the reseller of the disposition and, if the billing
                 dispute is resolved in favor of the reseller, applies credit
                 for the correct disputed amount, the disputed amount penalty
                 and/or late payment penalty as appropriate.

              C. If a billing dispute is resolved in favor of the Telephone
                 Company, any payments withheld pending resolution of the
                 dispute shall be subject to the late payment penalty (refer to
                 Section 6.4.1.4). Further, the reseller will not receive
                 credit for the disputed amount of the disputed amount penalty.

              D. If a reseller disputes a bill within three months of the
                 payment date and pays the total billed amount on or before the
                 payment date and the billing dispute is resolved in favor of
                 the reseller, the reseller will receive a credit for a
                 disputed amount penalty from the Telephone Company for the
                 period starting with the date of payment and ending on the
                 date of resolution. The credit for a disputed amount penalty
                 shall be as set forth following.

              E. If a reseller disputes a bill within three months of the
                 payment date and pays the total billed amount after the
                 payment date and the billing dispute is resolved in favor of
                 the reseller, the reseller will receive a credit for a
                 disputed amount penalty from the Telephone Company for the

                 starting with the date of dispute and ending on the date of
                 payment of the disputed amount or the date of resolution
                 whichever occurs first.

                 2. The disputed amount penalty shall be the disputed amount
                 resolved in the reseller's favor times a penalty factor. The

                 calculations.

              I. The reseller is responsible for monitoring the accuracy of
                 the Telephone Company's bills and for notifying the Telephone
                 Company of any discrepancies between such bills and the

                 conditions will be prorated to the number of days or major

6.5    RESALE

6.5.1  Description

        6.5.1.1  General

              A. Resale is the sale to another person of telecommunications
                 services purchased from the Telephone Company. A person
                 purchases for resale when such person purchases a service for
                 the purpose of reselling it to another (rather than the
                 purpose of using the service itself).

                 1. A purchasing agent who orders services for its principal,
                 and who does not itself agree to assume the obligations of a
                 reseller under these terms and conditions, is not purchasing
                 for resale within the meaning of these terms and conditions.

                 2. The purchase of telecommunications services or unbundled
                 network elements for the purpose of provisioning a different
                 service (such as the purchase of the Telephone Company's
                 switched carrier access service for the purpose of
                 provisioning an interexchange carrier's toll service) is not
                 resale within the meaning of these terms and conditions.

              B. Where a reseller purchases Telephone Company exchange
                 service from the Telephone Company and resells it to an end
                 user, such reseller's end user will be able to access any and
                 all services that a Telephone Company end user would be able
                 to access on a Telephone Company exchange service line. Such
                 services to the extent provided by the Telephone Company will
                 be deemed to have been sold to the reseller by the Telephone
                 Company as they are utilized by the reseller's end user, and
                 the reseller will be responsible to the Telephone Company for
                 payment of such services.

        6.5.1.2  Services Offered for Resale

              A. The services offered under these terms and conditions are

                 any applicable class of service restrictions for end users and

                         AMENDMENT TO RESALE AGREEMENTS

          This Amendment to Resale Agreements (this "Amendment"), dated as of
this ___ day of June, 1999 (the "Effective Date"), between New York Telephone
Company, d/b/a Bell Atlantic - Connecticut and Bell Atlantic - New York,
respectively, New England Telephone and Telegraph Company, d/b/a Bell
Atlantic - Maine, Bell Atlantic - Massachusetts, Bell Atlantic - New
Hampshire, Bell Atlantic - Rhode Island and Bell Atlantic - Vermont,
respectively, Bell Atlantic - Delaware, Inc., Bell Atlantic - District of
Columbia, Inc., Bell Atlantic - Maryland, Inc., Bell Atlantic - New Jersey,
Inc., Bell-Atlantic - Pennsylvania, Inc., Bell Atlantic - Virginia, Inc. and
Bell Atlantic - West Virginia, Inc. (individually and, collectively, as
applicable, "BA"), on the one hand, and collectively, as applicable, as
"Reseller", on the other hand (BA and Reseller individually being referred to
as a "Party" and, collectively, as the "Parties"). Reseller and

          WHEREAS, BA and Reseller are parties to _____ (x) Resale
Agreements, for the States of [Delaware, Maryland, New Jersey, Pennsylvania,
Virginia, Vermont, West Virginia, the District of Columbia, Maine,
Massachusetts, New Hampshire and Rhode Island], respectively (the foregoing
______ (x) agreements being referred to as the "Resale Agreements"), and
Reseller purchases services from BA for resale in the State of New York under
BA's New York resale tariff, and ReseIler plans to purchase services from BA
for resale in the State of Connecticut under BA's Connecticut resale tariff
and in the Commonwealth of Massachusetts under BA's Massachusetts resale
tariff;

          WHEREAS, Reseller wishes to obtain the Volume and Term Discount, the
Winback Discount and the lntraLATA Toll Discount, as applicable, referred to
herein on certain Eligible Services described herein that it purchases from BA
under the Resale Agreements and/or applicable BA resale tariffs, which Eligible
Services Reseller resells in respect of certain of the Qualified Business Lines
(as hereinafter defined), and BA is willing to provide such additional discounts
to Reseller, subject to the express terms and conditions set forth herein;

          WHEREAS, entry by BA into this Amendment is a voluntary act, not
required by and, in excess of the prescriptions under, the Telecommunications
Act of 1996 (the "TelAct") or any other applicable law;

          WHEREAS, while BA is entering into this Amendment to increase the
volume of resale business it conducts with resellers, because, among other
things, the arrangements set forth in this Amendment are new and untested in
the marketplace, BA is willing to enter into such arrangements with Reseller
and other resellers for only a limited time period and under certain
conditions (including, without limitation, as set forth

<PAGE>

in the next WHEREAS clause), after which BA will examine the effects of the
foregoing arrangements on its business and, at its sole option, determine
whether to continue this program in the future;

          WHEREAS, BA is willing to enter into amendments such as this
Amendment (and to enter into modifications of the terms of such amendments,
at BA's sole option, in the future), and to provide the foregoing additional
discounts, only with a single reseller or with multiple resellers (such as
the Reseller Companies) that are commonly wholly owned and controlled
(directly or indirectly) by the same parent company, which itself must become
a party to this Amendment) that, not later than November 30, 1999, enter into
(and submit their first order under) an amendment to resale agreements, a
separate agreement incorporating by reference the terms of applicable BA
resale tariffs for a particular reseller or an agreement that does both (on
terms satisfactory to BA that are substantially identical to the terms
hereof), and BA is not willing and is not required under the TelAct or other
applicable law to provide any such additional discounts pursuant to
negotiations under Section 251 of the TelAct (or any successor provision
thereto)(although BA expresses no opinion as to whether and, how, another
reseller may adopt, under Section 252(i) of the TelAct, the terms of the
Resale Agreements as amended hereby).

          NOW THEREFORE, in consideration of the mutual agreements set forth
below, and for other good and valuable consideration, the receipt and
sufficiency of which hereby are acknowledged, BA and Reseller hereby agree as
follows:

          1.     AMENDMENTS TO RESALE AGREEMENTS. Subject to the terms and
conditions set forth herein, the Parties hereby amend each of the Resale
Agreements and enter into a separate agreement incorporating by reference the
terms of BA's applicable resale Tariffs for the State of New York, the
Commonwealth of Massachusetts (and any other States within BA's local service
area, as of the date hereof, in which BA has a resale Tariff, from time to
time, under which Reseller purchases services from BA), as amended from time
to time, with respect only to Reseller, as follows:

          (a)    TERM OF RESALE AGREEMENTS. The stated term of each Resale
Agreement is hereby amended and restated so that each Resale Agreement,
unless terminated earlier in accordance with the terms thereof, shall expire
five (5) years from the date hereof, which date is May __, 2004. Such five
(5) year period commencing on the date hereof is referred to as the "Service
Term". Notwithstanding the foregoing, the right, if any, of a Party under any
Resale Agreement to terminate such Resale Agreement, other than due to a
breach thereof or at the end of the term thereof (as amended hereby), in each
case in accordance with the terms thereof, is hereby extinguished and shall
be of no effect.

          (b)    ANNUAL VOLUME COMMITMENT. (i) Subject to the terms and
conditions set forth herein, Reseller hereby agrees to purchase from BA,
under the

                                        2
<PAGE>

Resale Agreements and/or applicable BA resale tariffs, for resale by Reseller,
an aggregate number of business customer local exchange access lines, each of
which lines is designated with one of the USOC codes set forth in Appendix 1
hereto (each a "Qualified Business Line" and, collectively, the "Qualified
Business Lines") for each year of the Service Term (such minimum amount being
the "Annual Volume Commitment") in accordance with the following schedule:

             Year 1:     at least 50,000 Qualified Business Lines;
             Year 2:     at least 100,000 Qualified Business Lines; and
             Years 3-5:  at least 200,000 Qualified Business Lines each year;

provided, however, that a line shall not be counted as a Qualified Business
Line (and thus shall not be counted for purposes of the Annual Volume
Commitment Determination set forth below, and shall not receive the Volume
and Term Discount, the Winback Discount or the IntraLATA Toll Discount
described below) if such line (A) has been assigned by a third party customer
of BA to Reseller or any other reseller; provided further that a line type
set forth in Appendix 1 hereto and assigned by a third party customer of BA
to Reseller, where the ordering and administration of such assignment is
handled by the BA TISOC, shall be counted as a Qualified Business Line (and
thus shall be counted for purposes of the Annual Volume Commitment
Determination set forth below) but shall not receive the Volume and Term
Discount, the Winback Discount or the IntraLATA Toll Discount described below
or (B) is being purchased from BA under non-tariff based pricing (as
determined by BA) including, without limitation, ICB pricing or custom
pricing; provided further that a tariffed non-ICB Centrex-Registered
Trademark- line (e.g., a CustoFlex-Registered Trademark- 2100,
CustoPak-Registered Trademark-, Centrex Plus-Registered Trademark-,
Intellipath-Registered Trademark- or Intellipath II-Registered Trademark-
line) shall be counted as a Qualified Business Line (and thus shall be
counted for purposes of the Annual Volume Commitment Determination set forth
below) but shall not receive the Volume and Term Discount, the Winback
Discount or the IntraLATA Toll Discount described below; provided further,
that for purposes of this Amendment, Qualified Business Lines are defined in
terms of DS0 equivalents and, by way of example, one FlexPath-Registered
Trademark- line purchased by Reseller from BA under a Resale Agreement or
applicable BA resale Tariff for resale would equal twenty-four (24) Qualified
Business Lines.

          (ii)     The Annual Volume Commitment may be purchased by Reseller
from BA under a single effective Resale Agreement or applicable BA resale
tariff, or under multiple, effective Resale Agreements and/or applicable BA
resale tariffs (at Reseller's sole option), and the number of Qualified
Business Lines purchased by Reseller under each of the Resale Agreements and
the applicable BA resale tariffs for resale shall be considered in the
aggregate to ascertain the Annual Volume Commitment Determination hereunder;
provided, however, that unless BA, in its sole discretion, determines
otherwise, a line shall not be counted as a Qualified Business Line (and thus
shall not be counted for purposes of the Annual Volume Commitment
Determination set forth below, and shall not receive the Volume and Term
Discount, the Winback Discount or the IntraLATA Toll Discount described
below) if it is not included within BA's local service area as of the date
hereof.

<PAGE>

          (iii)    For the avoidance of any doubt, Reseller's purchase of
Qualified Business Lines and Eligible Services pursuant to this Amendment is for
the sole purpose of resale thereof and, as such, Reseller may not utilize any
Qualified Business Line, Eligible Service or portion thereof for its own use or
that of its parent, subsidiaries or affiliates and, in addition, Reseller may
not utilize any Eligible Service or portion thereof except in connection with
purchase of a Qualified Business Line hereunder (i.e., Reseller may not purchase
telecommunications services from BA on a stand alone basis).

          (c)      BA INTRALATA TOLL SERVICE. Reseller hereby agrees, at all
times during the Service Term, to have not less than eighty percent (80%) of the
Qualified Business Lines purchased by Reseller from BA presubscribed to BA's
IntraLATA Toll service. Reseller further agrees, during each year of the Service
Term, to purchase from BA, on a resold basis under the Resale Agreements and/or
applicable BA resale tariffs, with respect to such Qualified Business Lines, an
aggregate total number of minutes of use of BA's IntraLATA Toll service of not
less than the respective amounts set forth in Section 1(h)(ix) hereof.

          (d)      ANNUAL VOLUME COMMITMENT DETERMINATION. On an annual basis
beginning at the end of the first year of the Service Term, BA shall determine
the number of Qualified Business Lines purchased by Reseller from BA during the
immediately preceding year. Such number shall be referred to herein as the
"Annual Volume Commitment Determination" and shall equal, with respect to the
determinations made following each of the first three (3) years of the Service
Term, the average of the Qualified Business Lines that Reseller purchased from
BA hereunder that are actually in service on the last day of each of the last
three (3) consecutive months of the year in question. With regard to subsequent
years, the respective Annual Volume Commitment Determinations shall be
calculated as follows: the number of Qualified Business Lines purchased by
Reseller from BA hereunder that are actually in service on the last day of each
respective calendar quarter of the year in question shall be added together,
and the resulting sum shall be divided by four (4).

          (e)      ANNUAL VOLUME COMMITMENT MEASUREMENT. On an annual basis
beginning at the end of the first year of the Service Term, BA shall compare
Reseller's actual annual attainment of Qualified Business Lines as determined
in accordance with Section 1(d) hereof to the defined target volumes in Table
1 below. Such comparison shall be referred to herein as the "Annual Volume
Commitment Measurement". As further set forth in Section 1(f) hereof, the
Annual Volume Commitment Measurement shall confirm the appropriate level of the
Volume and Term Discount for the year just completed and determine the
applicable Volume and Term Discount for the following year.

The Tier 1 target volumes for each of the first three (3) years of the
Service Term shall be set at two (2) separate ranges, Tier 1(A) and Tier
1(B). During this period of the Service Term when the Annual Volume
Commitment Determination falls within Tier 1, the actual "Tier 1 range (i.e.,
Tier 1(A) or Tier 1(B)) used for the Annual Volume Commitment Measurement
will be based on Reseller's attainment of the Annual Volume Commitment set
forth in Section 1(b) hereof. Specifically, if Reseller's Qualified Business
Line volume, as counted on the last day of the last month of the year in
question, is greater than or equal to the Annual Volume Commitment set forth
in Section 1(b) hereof for the same year, then Tier 1(A) will be used for the
Annual Volume Commitment Measurement. If Reseller's Qualified Business Line
volume, as counted on the last day of the last month of the year in question,
is less than the Annual Volume Commitment set forth in Section 1(b) hereof
for the same year, then Tier 1(B) will be used for the Annual Volume
Commitment Measurement.

          (f)      MINIMUM PURCHASE. (i) Subject to the terms of this
Amendment, for each year of the Service Term, Reseller shall purchase a
minimum quantity of Qualified Business Lines not less than the applicable
Annual Volume Commitment, as calculated using the Annual Volume Commitment
Determination.

          (ii)     If the Annual Volume Commitment Determination following the
first year of the Service Term does not yield a number of Qualified Business
Lines equal to at least 30,000, BA may, at its option, terminate this
Amendment. In case of such termination, Reseller shall, within thirty (30)
days of receipt of written demand therefor, pay to BA in immediately
available funds (in addition to any other amounts owed to BA under the Resale
Agreements and/or applicable BA resale tariffs), an amount equal to (A) all
of the discounts under this Amendment that Reseller received from the point
of termination back to the Effective Date of this Amendment, plus (B)
interest on such discounts dating back to the date received from BA
calculated using an interest rate equal to the greater of (1) the "Prime"
interest rate as set forth in The Wall Street Journal from time to time and
(2) the interest rate that Reseller demonstrates to BA's reasonable

                                       5
<PAGE>

satisfaction that it has obtained (or can demonstrate to BA's reasonable
satisfaction that it could obtain) from a commercial lender for loan amounts
equal to not less than the entire amount to be paid to BA under the applicable
subsection (e.g., subsection 1(f)(ii) or 1(g)(i), etc.) of this Amendment with
a maturity of not less than one (1) year (the foregoing being the "Applicable
Interest Rate"), plus (C) any applicable taxes relating thereto, plus (D) a
handling fee equal to five percent (5%) of the amount of the discounts under
this Amendment that Reseller received.

          (iii)    If the Annual Volume Commitment Determination following the
second year of the Service Term does not yield a number of Qualified Business
Lines equal to at least 60,000, BA may, at its option, terminate this Amendment.
In case of such termination, Reseller shall, within thirty (30) days of receipt
of written demand therefor, pay to BA in immediately available funds (in
addition to any other amounts owed to BA under the Resale Agreements and/or
applicable BA resale tariffs), an amount equal to (A) all of the discounts
under this Amendment that Reseller received from the point of termination back
to the Effective Date of this Amendment, plus (B) interest on such discounts
dating back to the date received from BA calculated using the Applicable
Interest Rate, plus (C) any applicable taxes relating thereto, plus (D) a
handling fee equal to five percent (5%) of the amount of the discounts under
this Amendment that Reseller received.

          (iv)     If the Annual Volume Commitment Determination following the
third year of the Service Term does not yield a number of Qualified
Business Lines equal to at least 100,000, BA may, at its option, terminate
this Amendment. In case of such termination, Reseller shall, within thirty
(30) days of receipt of written demand therefor, pay to BA in immediately
available funds (in addition to any other amounts owed to BA under the
Resale Agreements and/or applicable BA resale tariffs), an amount equal to
(A) all of the discounts under this Amendment that Reseller received from the
point of termination back to the Effective Date of this Amendment, plus (B)
interest on such discounts dating back to the date received from BA
calculated using the Applicable Interest Rate, plus (C) any applicable taxes
relating thereto, plus (D) a handling fee equal to five percent (5%) of the
amount of the discounts under this Amendment that Reseller received.

          (v)      If the Annual Volume Commitment Determination following the
fourth year of the Service Term does not yield a number of Qualified Business
Lines equal to at least 100,000, BA may, at its option, terminate this
Amendment. In case of such termination, Reseller shall, Within thirty (30)
days of receipt of written demand therefor, pay to BA in immediately
available funds (in addition to any other amounts owed to BA under the Resale
Agreements and/or applicable BA resale tariffs), an amount equal to (A) all
of the discounts under this Amendment that Reseller received during the year
in question, plus (B) interest on such discounts dating back to the date
received from BA calculated using the Applicable Interest Rate, plus (C) any
applicable taxes relating thereto, plus (D) a handling fee equal to five
percent (5%) of the amount of the discounts under this Amendment that
Reseller received during the year in

                                        6
<PAGE>

question.

          (vi)     BA will monitor Reseller's monthly volumes of Qualified
Business Lines during the fifth year of the Service Term to ensure compliance
with minimum commitment requirements, i.e., greater than or equal to 100,000
Qualified Business Lines. If Reseller's volumes should fall below 100,000 as
of the last day of any month, then BA may, at its option, terminate this
Amendment. In case of such termination, Reseller shall, within thirty (30)
days of receipt of written demand therefor, pay to BA in immediately
available funds (in addition to any other amounts owed to BA under the Resale
Agreements and/or applicable BA resale tariffs), an amount equal to (A) all
of the discounts under this Amendment that Reseller received during the year
in question, plus (B) interest on such discounts dating back to the date
received from BA calculated using the Applicable Interest Rate, plus (C) any
applicable taxes relating thereto, plus (D) a handling fee equal to five
percent (5%) of the amount of the discounts under this Amendment that
Reseller received during the year in question.

          (g)      TERMINATION CHARGE. (i) In each case during the first three
(3) years of the Service Term, if Reseller terminates any of the Resale
Agreements or this Amendment, or if BA in its discretion terminates any of
the Resale Agreements or this Amendment due to breach, or if Reseller ceases
to be a certified reseller (and does not restore its certification within
forty-five (45) days of the loss or expiration of certification) in each
State in which it has a Resale Agreement with BA or purchases services from
BA under an applicable BA resale tariff, Reseller shall, within thirty (30)
days of receipt of written demand therefor, pay to BA in immediately
available funds (in addition to any other amounts owed to BA under the Resale
Agreements and/or applicable BA resale tariffs), an amount equal to (A) all
of the discounts under this Amendment that Reseller received from the point
of termination back to the Effective Date of this Amendment (less the
amounts, if any, previously refunded by Reseller to BA under this Amendment),
plus (B) interest on such discounts dating back to the date received from BA
calculated using the Applicable Interest Rate, plus (C) any applicable taxes
relating thereto, plus (D) a handling fee equal to five percent (5%) of the
amount of the discounts under this Amendment that Reseller received.

          (ii)     In each case during the fourth and fifth years of the Service
Term, if Reseller terminates any of the Resale Agreements or this Amendment, or
if BA in its discretion terminates any of the Resale Agreements or this
Amendment due to breach, or if Reseller ceases to be a certified reseller (and
does not restore its certification within forty-five (45) days of the loss or
expiration of certification) in each State in which it has a Resale Agreement
with BA or purchases services from BA under an applicable BA resale tariff,
Reseller shall, within thirty (30) days of receipt of written demand therefor,
pay to BA in immediately available funds (in addition to any other amounts owed
to BA under the Resale Agreements and/or applicable BA resale tariffs), an
amount equal to (A) all of the discounts under this Amendment that Reseller
received during the number of months or portions thereof in the year of the
Service Term in which termination or loss of certification occurs, plus (B)
interest on such discounts

                                        7

dating back to the date received from BA calculated using the Applicable
Interest Rate, plus (C) any applicable taxes relating thereto, plus (D) a
handling fee equal to five percent (5%) of the amount of the discounts under
this Amendment that Reseller received during the year in question.

          (h)      ADDITIONAL DISCOUNTS.  (i) Subject to Reseller having met
each of the conditions set forth in Section 2 of this Amendment, and subject
also to the other conditions set forth in this Amendment, Reseller shall
receive, on each of the Qualified Business Lines being purchased from BA and
resold hereunder as part of the Annual Volume Commitment, during the Service
Term only, an additional (A) four percent (4%) to twelve percent (12%)
discount, as applicable (the "Volume and Term Discount), in accordance with
the schedule set forth in Table 2 following, (B) an additional ten percent
(10%) discount (the "Winback Discount") to the extent applicable under
subsection (h)(ii) below and (C) an additional three percent (3%) discount
(the "IntraLATA Toll Discount"), to the extent applicable under subsection
(h)(ix) below, in each case on certain services, as set forth on Appendix 1
hereto (each an "Eligible Service" and, collectively, the "Eligible
Services"), that Reseller purchases under any of the Resale Agreements and/or
applicable BA resale tariffs; provided, however, such Volume and Term
Discount, Winback Discount and IntraLATA Toll Discount, at BA's sole option,
shall not apply to Qualified Business Lines in any month in excess of 500,000
purchased by Reseller from BA for resale; and provided further, that such
Volume and Term Discount, Winback Discount and IntraLATA Toll Discount shall
not apply to Centrex-Registered Trademark- lines (even with respect to such

          The Volume and Term Discount, Winback Discount and IntraLATA Toll
Discount on BA's applicable retail prices for the foregoing services is
exclusive of and, in addition to, the respective wholesale discounts to which
Reseller may be entitled under

                                        8
<PAGE>

the Resale Agreements or applicable BA resale tariffs, as amended from time
to time, prior to giving effect to this Amendment (the "Existing Wholesale
Discounts"); provided, however, that to the extent Reseller obtains such
Eligible Services without also purchasing BA's operator services and
directory assistance, the amount of the Volume and Term Discount, Winback
Discount and IntraLATA Toll Discount shall be reduced, as necessary, to give
effect to an Existing Wholesale Discount based upon purchase by Reseller of
BA's operator services and directory assistance. Any services with respect to
a Qualified Business Line that Reseller purchases from BA under a Resale
Agreement or applicable BA resale tariff, but which are not Eligible
Services, or which are Eligible Services but are purchased by Reseller
pursuant to a BA promotional discount (given at the retail and/or the
wholesale level) or pursuant to or in connection with a volume, term or other
discount under an applicable BA tariff or contractual arrangement (regardless
of the parties thereto) other than the Resale Agreements, shall not qualify
for the Volume and Term Discount, Winback Discount or IntraLATA Toll Discount
and no such Volume and Term Discount, Winback Discount or IntraLATA Toll
Discount shall be applied thereto. With the exception of the Business Link,
Key Connections, and Rewarding Connections Optional Calling Plans, neither
the IntraLATA Toll Discount nor the Volume and Term Discount shall apply to
services (whether or not Eligible Services) purchased under an optional
calling plan, although minutes of use purchased by Reseller from BA under an
IntraLATA Toll optional calling plan shall be counted for purposes of
calculations to determine whether Reseller met the applicable MOU Target, as
defined and, further set forth in, subsection (ix) below.

          (ii)     Upon receipt by BA of written notice from Reseller, in which
Reseller represents and warrants that a Qualified Business Line (excluding
Centrex-Registered Trademark- lines that are Qualified Business Lines) was
not on the BA network (other than with respect to purchase of number
portability services from BA) for at least the immediately preceding ninety
(90) day period, but is now being converted to the BA network from a carrier
other than Reseller that is not an affiliate of Reseller, BA shall provide
to Reseller (unless BA reasonably believes, in its sole discretion, that
Reseller is materially inaccurate with respect to the foregoing notice
including, without limitation, due to such inaccuracy in Reseller's previous
notices) an additional Winback Discount on its purchase of Eligible Services
in respect of such line (effective from the date of conversion to the BA
network), so long as such line remains on the BA network (and the entity from
which the conversion to the BA network was made remains a non-affiliate of
Reseller), provided that the Winback Discount shall not apply beyond the
twelve (12) month period immediately after the date of such conversion. For
purposes of the foregoing, being on "the BA network" shall be determined by BA
in its sole reasonable discretion including, without limitation, with
reference to the end user customer's telephone number (as opposed to the end
user customer's name). Upon receipt of a request from BA, Reseller shall
provide to BA a copy of documentation reasonably requested by BA to support
Reseller's claim that a line is eligible for the Winback Discount. Such
documentation may include, but is not limited to, the following: (A) orders
or similar documentation for number portability from a CLEC network to the BA
network for the affected line; (B) orders or similar documentation
demonstrating that

                                        9
<PAGE>

any lines being converted from a CLEC network to the BA network on a
disconnect/new connect basis (in lieu of number portability) are one in the
same; and (C) other documentation as reasonably requested by BA from time to
time. In addition to any other audit rights BA may have under the Resale
Agreements and/or applicable BA tariffs, BA shall have the right (but not the
obligation) to audit Reseller to ascertain whether Reseller is complying
with the foregoing requirements with respect to eligibility for the Winback
Discount.

          (iii)    Subject to repayment under the terms of this Amendment,
during the first year of the Service Term the Volume and Term Discount shall
equal seven percent (7%) if the Annual Volume Commitment Measurement reflects
Tier 1 volume attainment or four percent (4%) if the Annual Volume Commitment
Measurement reflects Tier 2 volume attainment.

          (iv)     Subject to repayment under the terms of this Amendment,
during the second year of the Service Term the Volume and Term Discount shall
equal ten percent (10%) if the Annual Volume Commitment Measurement reflects
Tier 1 volume attainment or seven percent (7%) if the Annual Volume
Commitment Measurement reflects Tier 2 volume attainment.

          (v)      Subject to repayment under the terms of this Amendment,
during the third through fifth years of the Service Term the Volume and Term
Discount shall equal twelve percent (12%) if the Annual Volume Commitment
Measurement reflects Tier 1 volume attainment or ten percent (10%) if the
Annual Volume Commitment Measurement reflects Tier 2 volume attainment or
seven percent (7%) if the Annual Volume Commitment Measurement reflects Tier
3 volume attainment.

          (vi)     As set forth in subsection (iii) above, upon the Effective
Date of this Amendment, Reseller will receive a seven percent (7%) Volume and
Term Discount on the assumption that Reseller will purchase, as measured
through the Annual Volume Commitment Measurement, Tier 1 volumes for the
first year of the Service Term. For each subsequent year of the Service Term,
the applicable discount will be from the same Tier used for the previous
year. For example, if Reseller purchased Qualified Business Line volumes in
year 2 that, as measured through the Annual Volume Commitment Measurement,
equated to the Tier 2 discount for year 2, then Reseller would enter year 3
with the applicable Tier 2 discount for year 3. See Table 2 in Section
1(h)(i).

          (vii)    For any year of the Service Term when the actual purchased
Qualified Business Line volumes, as calculated by the Annual Volume
Commitment Determination, equate to a lesser Volume and Term Discount than
what was actually billed, Reseller shall refund, for the applicable year in
question, an amount equal to the difference between the "billed" discount and
the "earned" discount. In case of such excess discounting, Reseller shall,
within thirty (30) days of receipt of written demand therefor, pay to BA in
immediately available funds (in addition to any other amounts

                                       10
<PAGE>

owed to BA under the Resale Agreements and/or applicable BA resale tariffs),
an amount equal to (A) the difference between the "billed" and "earned"
Volume and Term Discounts under this Amendment that applied during the year
in question, plus (B) interest on the difference in Volume and Term Discounts
dating back to the date received from BA calculated using the Applicable
Interest Rate, plus (C) any applicable taxes relating thereto. Such payment
will be based on the actual lines in service on the last day of each month
during the year in question.

          (viii)   For any year of the Service Term when the actual purchased
Qualified Business Line volumes, as calculated by the Annual Volume
Commitment Determination, equate to a greater Volume and Term Discount than
what was actually billed, Reseller may request a credit, for the applicable
year in question, in an amount equal to the difference between the "billed"
discount and the "earned" discount. In case of such under-discounting, BA
shall, within thirty (30) days of receipt of written demand therefor, credit
the applicable Reseller account(s), an amount equal to (A) the difference
between the "billed" and "earned" Volume and Term Discounts under this
Amendment that applied during the year in question, plus (B) interest on the
difference in Volume and Term Discounts dating back to the date received from
BA equal to the "Prime" interest rate as set forth in The Wall Street Journal
from time to time, plus (C) any applicable taxes relating thereto.

          (ix)     (A) Notwithstanding the provisions of subsection (h)(i)
above to the contrary, if, during any year of the Service Term, Reseller
fails to (x) have at least eighty percent (80%) of its Qualified Business
Lines presubscribed to BA's IntraLATA Toll service (the "IntraLATA Toll
Presubscription Commitment"), the IntraLATA Toll Discount for the next
succeeding year of the Service Term shall be reduced by two percent (2%)
(i.e., from three percent (3%) to one percent (1%)) or (y) purchase from BA
at least the applicable minimum aggregate total number of minutes of use of
BA's IntraLATA Toll service as set forth below in this subsection (ix) (the
"MOU Target"), the IntraLATA Toll Discount for the next succeeding year of the
Service Term shall be reduced by one percent (1%) (i.e., from three percent
(3%) to two percent (2%)); provided, however, that, for the avoidance of any
doubt, if Reseller fails to meet the applicable requirements under both
subsections (x) and (y) above, the amount of the IntraLATA Toll Discount
for the next succeeding year of the Service Term shall be reduced to zero
(0); provided further that, if Reseller fails to meet the applicable
requirements under either or both of subsections (x) and (y) above in respect
of the fifth year (or other year if, for whatever reason, the last year of
the Service Term is not the fifth year) of the Service Term, Reseller shall,
within thirty (30) days of receipt of written demand therefor, pay to BA in
immediately available funds, the amount of the IntraLATA Toll Discount to
which it was not entitled during the fifth year (or other year if, for
whatever reason, the last year of the Service Term is not the fifth year) of
the Service Term (i.e., the two percent (2%) discount referenced above if
Reseller did not meet the eighty percent (80%) IntraLATA Toll Presubscription
Commitment, and the one percent (1%) discount referenced above if Reseller
did not meet the MOU Target requirement).

                                       11
<PAGE>

                   (B) Reseller may, upon sixty (60) days written notice,
terminate the IntraLATA Toll Service Presubscription Commitment and MOU
Target requirement applicable under this Amendment for any BA jurisdiction
(i.e., a particular State or the District of Columbia) without incurring a
penalty. Upon the effective date of such termination, BA shall cease the
application of the IntraLATA Toll Discount for such jurisdiction and
determine, on a pro rata basis, Reseller's attainment of minutes of use and
BA presubscription commitments during the number of months or portions
thereof in the year of the Service Term in which termination occurs. If
Reseller fails to meet the applicable requirements under either or both of
subsections (x) and (y) above, Reseller shall, within thirty (30) days of
receipt of written demand therefor, pay to BA in immediately available funds,
the amount of the IntraLATA Toll Discount to which it was not entitled during
the number of months or portions thereof in the year of the Service Term in
which termination occurs (i.e., the two percent (2%) discount referenced
above if Reseller did not meet the eighty percent (80%) IntraLATA Toll
Presubscription Commitment, and the one percent (1%) discount referenced
above if Reseller did not meet the MOU Target requirement).

                   (C) During the first year of the Service Term, the MOU
Target shall equal the product of (x) forty (40), multiplied by (y) forty
percent (40%) of the sum obtained by adding the number of Qualified Business
Lines purchased by Reseller from BA hereunder as of the last day of the first
and last months, respectively, of the first year of the Service Term (the
resulting number of lines not to exceed 50,000), multiplied by (z) twelve
(12) months. By way of example only, if Reseller purchased from BA hereunder
20,000 Qualified Business Lines as of the last day of the first month of the
first year of the Service Term and 50,000 Qualified Business Lines as of the
last day of the last month of the first year of the Service Term, the MOU
Target for the first year of the Service Term would be the product of the
following: forty (40), multiplied by .40, multiplied by 70,000 (which is the
sum of 20,000 and 50,000), multiplied by twelve (12) -- which equals
13,440,000 minutes of use of BA's IntraLATA Toll service.

                   (D) During subsequent years of the Service Term, the MOU
Target shall be determined by BA as set forth below; provided, however, that
for the purposes of such calculations, at no time shall the average number of
minutes of use per month of BA's IntraLATA Toll service purchased hereunder
by Reseller from BA per Qualified Business Line (the "Average Monthly MOU Per
Line") be less than forty (40) minutes).

                   (E) During the second year of the Service Term, the MOU
Target shall equal the product of (x) the greater of forty (40) or the
Average Monthly MOU Per Line during the first year of the Service Term
multiplied by .90, multiplied by (y) forty percent (40%) of the sum obtained
by adding the number of Qualified Business Lines purchased by Reseller from
BA hereunder as of the last day of the first and last months, respectively,
of the second year of the Service Term (the resulting number of lines not to
exceed 100,000), multiplied by (z) twelve (12) months. By way of example
only, if Reseller's Average Monthly MOU Per Line for the first year of the
Service Term was

                                       12
<PAGE>

sixty (60) and Reseller purchased from BA hereunder 60,000 Qualified Business
Lines as of the last day of the first month of the second year of the Service
Term and 100,000 Qualified Business Lines as of the last day of the last
month of the second year of the Service Term, the MOU Target for the second
year of the Service Term would be the product of the following: 54 (which is
the product of 60 and .90), multiplied by .40, multiplied by 160,000 (which
is the sum of 60,000 and 100,000), multiplied by twelve (12) -- which equals
41,472,000 minutes of use of BA's IntraLATA Toll service.

                   (F) During the third year of the Service Term, the MOU
Target shall equal the product of (x) the greater of forty (40) or the
Average Monthly MOU Per Line during the second year of the Service Term
multiplied by .90, multiplied by (y) forty percent (40%) of the sum obtained
by adding the number of Qualified Business Lines purchased by Reseller from
BA hereunder as of the last day of the first and last months, respectively,
of the third year of the Service Term (the resulting number of lines not to
exceed 200,000), multiplied by (z) twelve (12) months. By way of example
only, if Reseller's Average Monthly MOU Per Line for the second year of the
Service Term was sixty (60) and Reseller purchased from BA hereunder 110,000
Qualified Business Lines as of the last day of the first month of the third
year of the Service Term and 200,000 Qualified Business Lines as of the last
day of the last month of the third year of the Service Term, the MOU Target
for the third year of the Service Term would be the product of the following:
54 (which is the product of 60 and .90), multiplied by .40, multiplied by
310,000 (which is the sum of 110,000 and 200,000), multiplied by twelve (12)
-- which equals 80,352,000 minutes of use of BA's IntraLATA Toll service.

                   (G) The respective MOU Targets for each of the fourth and
fifth years of the Service Term shall equal the product of (x) the greater of
forty (40) or the Average Monthly MOU Per Line during the immediately
preceding year of the Service Term multiplied by .90, multiplied by (y)
eighty percent (80%) of the Annual Volume Commitment Determination for the
immediately preceding year of the Service Term (the resulting number not to
exceed 200,000), multiplied by (z) twelve (12) months. By way of example
only, if Reseller's Average Monthly MOU Per Line for the fourth year of the
Service Term was sixty (60) and the Annual Volume Commitment Determination
for the fifth year of the Service Term was 200,000, the MOU Target for the
fifth year of the Service Term would be the product of the following: 54
(which is the product of 60 and .90), multiplied by .80, multiplied by
200,000, multiplied by twelve (12) -- which equals 103,680,000 minutes of
use of BA's IntraLATA Toll service

          (x) Notwithstanding any provisions of this subsection (h) to the
contrary, the amount of the Volume and Term Discount, the Winback Discount
and the IntraLATA Toll Discount in any State shall be reduced, if and as
necessary, to the extent that, absent such reduction, the sum of the Volume
and Term Discount, the IntraLATA Toll Discount and the Existing Wholesale
Discount in effect from time to time in such State would exceed the sum of
the amount of the Existing Wholesale Discount in effect on the date hereof in
such State plus fifteen percent (15%).

          2.       CONDITIONS TO APPLICATION OF ADDITIONAL DISCOUNTS. BA may,
at its sole discretion, withhold from Reseller some or all of the Volume and
Term Discount, Winback Discount and IntraLATA Toll Discount under one, some
or all of the Resale Agreements and/or applicable BA tariffs, at any time
and, from time to time, if Reseller does not place its first order for an
Eligible Service hereunder by November 30, 1999, or if Reseller materially
defaults in performing any of its material obligations under any Resale
Agreement, applicable BA tariff or other contractual arrangement between
Reseller (or any affiliate of Reseller) and BA (or any affiliate of BA), and
such default is not cured at the time BA prepares the applicable monthly
bill(s) for submittal to Reseller. Such a material default includes, without
limitation, failure by Reseller to fulfill any of the obligations set forth
in the subsections of this Section 2, the breach of which, for the avoidance
of doubt, however, shall not affect the respective Existing Wholesale
Discounts to which Reseller may be entitled under the Resale Agreements or
applicable BA resale tariffs prior to giving effect to this Amendment. In
such case, if BA exercises its discretion and withholds some or all of the
Volume and Term Discount, Winback Discount or IntraLATA Toll Discount, once
the default is cured BA may, at its sole option, release none, some or all of
the withheld portion of the Volume and Term Discount, Winback Discount or
IntraLATA Toll Discount. If BA opts not to release all of any such withheld
portions, Reseller shall have no right to any of the unreleased amounts.

               (a)     ELECTRONIC ORDERS. Notwithstanding any provisions of a
Resale Agreement or applicable BA resale tariff to the contrary, all orders
submitted by Reseller to BA pursuant to any of the Resale Agreements or
applicable BA resale tariffs, whether or not in respect of Eligible Services
set forth in Appendix 1 hereto, shall be submitted via an electronic
interface approved by BA for the provisioning of services under a resale
arrangement.

               (b)     ASSIGNMENTS AND MERGERS/ACQUISITIONS. Without the
prior written consent of BA (which may be withheld by BA in its sole
discretion), a Reseller Company shall not assign any of its respective rights
or obligations under any of the Resale Agreements or under this Amendment (or
under any other resale agreement or related agreement, in the case of another
entity that becomes a Reseller Company), and shall not accept an assignment
to it of any of the respective rights or obligations of another entity under
a resale agreement or related agreement with BA. If a Reseller Company merges
with another entity or acquires another entity (or if the parent company of
the Reseller Companies (currently Reseller Holdings) is acquired by another
entity), which other entity in any case, prior to such merger or acquisition,
was not a party to a resale volume and term discount arrangement with BA, the
applicable Reseller Company may elect to count Qualified Business Lines being
purchased by such other entity from BA as Qualified Business Lines hereunder
for purposes of the Annual Volume Commitment Determination (and such lines
shall be eligible for the discounts available under this Amendment in
accordance with the terms hereof); provided that upon BA's request, the
Reseller Company and/or such other entity (which shall then be deemed to be a
Reseller Company) shall first execute such documents as BA reasonably deems

                                      14
<PAGE>

necessary to give effect to the terms of this Amendment, particularly to
amend the terms and conditions of the applicable resale agreements of the
other entity in a manner substantially identical to the terms and conditions
of this Amendment; provided further that BA may, at its discretion, cease
counting Qualified Business Lines being purchased in respect of the acquired,
acquiring or merged with Reseller Company as Qualified Business Lines
hereunder for purposes of the Annual Volume Commitment Determination (and
such lines shall cease being eligible for the discounts available under this
Amendment and any such related documents) if any of the applicable Reseller
Companies (to include the other entity acquired, acquiring or to which
merged) fails, within one hundred eighty (180) days of the effective date of
such merger or acquisition, to exclusively utilize the same type of
electronic interface (e.g., Web-GUI, EDI, etc.), to include, without
limitation, the applicable version thereof, with BA on a State by State basis
(to include the District of Columbia), as the type of such electronic
interface (to include, without limitation, the applicable version thereof)
used by the other Reseller Companies for such jurisdiction; the foregoing
shall also apply in the case of Reseller Inc., Reseller LLC or Reseller
Holdings ceasing to utilize the same such type of electronic interface (to
include, without limitation, the applicable version thereof) with BA on a
State by State basis. If a Reseller Company merges with another entity or
acquires another entity (or if the parent company of the Reseller Companies
(currently Reseller Holdings) is acquired by another entity), which other
entity in any case, prior to such merger or acquisition, was a party to a
resale volume and term discount arrangement with BA, the Reseller Company
and/or such other entity, as applicable, shall be responsible for fulfilling
their respective obligations to BA under both this Amendment and such other
resale volume and term discount arrangement.

          (c)      ORDER QUALITY. At least ninety-five percent (95%) of
Reseller's orders submitted to BA during each month of the Service Term
(whether or not in respect of Eligible Services set forth in Appendix 1
hereto) shall not contain errors or omissions such that they are rejected by
BA or require queries from BA to Reseller. In addition, Reseller shall submit
such orders so that at least ninety percent (90%) of Flow Through Eligible
Orders actually flow through; a "Flow Through Eligible Order" does not
require manual intervention by BA. Upon the first billing cycle month of the
Service Term in which one or both of the above conditions is not met,
Reseller agrees, upon reasonable request by BA, to meet with BA promptly and
in good faith to determine the reasons that the foregoing percentage(s) was
not met and to develop a plan for improvement. If Reseller does not meet
either of such conditions for a second consecutive month, Reseller agrees,
upon reasonable request by BA, to meet with BA promptly and in good faith to
determine the reasons that the foregoing percentage(s) was not met and to
develop a plan for improvement. If Reseller does not meet either of such
conditions for a third consecutive month, Reseller shall be deemed to have
materially defaulted in performing under this subsection, and BA may, at its
sole option, not apply the Volume and Term Discount, Winback Discount and/or
IntraLATA Toll Discount to Eligible Services purchased by Reseller from BA
under the Resale Agreements and/or applicable BA resale tariffs until
Reseller first meets both such conditions in a subsequent month of the
Service Term.

                                       15
<PAGE>

          (d)      FORECASTS. Reseller shall provide to BA accurate and
timely forecasts in accordance with BA's forecasting requirements as in
effect from time to time (as currently set forth in Section 8.4 of Volume 1
of BA's Resale Handbook series), at least twice a year during the Service
Term, of the Eligible Services under each Resale; Agreement or applicable BA
resale tariff that Reseller anticipates purchasing from BA.

          (e)      COOPERATION WITH BA PROCESSES/JOINT EFFORTS TO INCREASE
EFFICIENCY. Each Party shall use commercially reasonable efforts to comply
with the other Party's reasonable requests aimed at increasing the efficiency
of the ordering and maintenance processes under the Resale Agreements and/or
applicable BA resale tariffs. Such requests may include, without limitation
that Reseller personnel attend training sessions from time to time regarding
ordering, that Reseller use certain reference materials designated by BA that
are designed to limit the number of calls made to BA's Help Desk, that
Reseller participate in Industry Change Control meetings held from time to
time by BA, that Reseller use pre-order functionalities established by BA to
validate addresses, to determine feature availability, to reserve telephone
numbers and the like, and that representatives of the Parties meet, from time
to time, to discuss means by which such efficiency can be improved,.

          3.       LIMITED AMENDMENTS. The amendments set forth in this
Amendment shall be limited precisely as written and shall not be deemed to
(a) be an amendment to or waiver of any other term or condition of the Resale
Agreements or of any other instrument, tariff, SGAT or agreement referred to
therein; or (b) prejudice any right or remedy that either Party may have in
the future under or in connection with the Resale Agreements or any
instrument, tariff, SGAT or agreement referred to therein. For the avoidance
of doubt, any and all amounts due to BA under the terms of this Amendment
shall be subject, in addition to the specific remedies set forth in this
Amendment, also (at BA's sole option) to the remedies and procedures set
forth in the Resale Agreements and/or applicable BA tariffs; provided,
however, that in the event Reseller shall fail to (a) purchase a quantity of
Qualified Business Lines at least equal to the applicable Annual Volume
Commitment, (b) have at least eighty percent (80%) of its Qualified Business
Lines, presubscribed to BA's IntraLATA Toll Service or (c) satisfy the
applicable MOU Target, Reseller's liability, and BA's sole claim and
recourse, with respect to any such failure, shall be limited to (w) not
providing to Reseller the applicable discounts under this Amendment, (x)
repayment of all of the discounts under this Amendment that Reseller received
during the period in question, together with interest on such discounts
dating back to the date received from BA calculated using the Applicable
Interest Rate, as well as any applicable taxes relating thereto and a
handling fee equal to five percent (5%) of the amount of the discounts under
this Amendment that Reseller received during the period in question and (z)
termination of this Amendment, to the extent applicable, in each case in
accordance with the terms of this Amendment..

          4.       RATIFICATION OF RESALE AGREEMENTS: NO CHALLENGES. This
Amendment shall be construed in connection with and, as a part of, the Resale
Agreements, and all terms, conditions, representations, warranties,
covenants, and agreements set forth in the Resale Agreements, except as
herein amended or waived, are hereby ratified and confirmed and shall remain
in full force and effect. In addition, Reseller hereby expressly agrees not
to challenge the reasonableness, enforceability, validity, legality or the
like, of any term or condition in any of the Resale Agreements or in this
Amendment, either before a court or regulatory authority of competent
jurisdiction, or otherwise.

          5. CLAIMS. (a) DEFINITION OF CLAIMS. For purposes of this Amendment,
"Claims" means any and all manner of liabilities, obligations, causes of
action, in law or equity, complaints, actions, demands, suits, debts, dues,
judgments, executions, costs, expenses and other claims of any and every
kind, arising under any theory of contract, tort, fraud, breach of duty,
strict liability, or any other theory of liability, based on any federal,
State, or local law, code, statute, rule or regulation or the common or civil
law of any jurisdiction, known or unknown, fixed or contingent, suspected or
unsuspected, or latent, concealed or hidden, that a Party asserted or could
have asserted against the other Party as of the Effective Date or before such
date; provided, however, that "Claims" shall not include any right, duty or
obligation that by the terms of Section 5(c)(ii) hereof remains in full force
and effect and is not limited or waived.

          (b)      DEFINITION OF PARTIES. For purposes of and, in connection
with, the release contained in this Amendment, references to a Party include
such Party and each of its shareholders, parents, subsidiaries, assigns,
predecessors and successors in interest, partners, agents and affiliates, and
the officers, directors, employees, controlling persons, shareholders,
servants, representatives, attorneys, administrators, partners, agents and
affiliates of each of them and all parties acting by, through, under or in
concert with each of them, past or present.

          (c)      RELEASE OF CLAIMS. (i) On the Effective Date, Reseller
hereby, releases, remixes, acquits and forever discharges BA from and against
any and all Claims of Reseller against BA.

                   (ii) Each Party agrees that with respect to those
agreements between them, as amended by the terms of this Amendment and any
other documents entered into in connection herewith, the lawful obligations
and duties of such agreements shall be in full force and effect as of the
Effective Date and henceforth.

          (d)      DELIVERY OF RELEASES IN FUTURE. Reseller agrees, for the
benefit of BA and at its own expense, that now and in the future it will
execute and deliver to BA any releases of judgment, liens, bonds or
encumbrances (whether statutory, common law or otherwise) in favor of
Reseller arising out of or with respect to the Claims of Reseller or the
subject matter thereof, and any releases of mortgage, termination statements
or other similar instruments that are necessary or advisable to release and

                                       17
<PAGE>

discharge of record all liens, security interests and other encumbrances in
favor of Reseller under or with respect to the Claims of Reseller and that it
will now and in the future pay all taxes (other than taxes imposed on or
measured by the income of BA), costs or expenses, if any, upon any documents
or transactions relating thereto.

          (e)      FULL AND FINAL RELEASE. This Amendment is a full and final
release applying not only to such of the Claims of Reseller as are presently
known, anticipated or disclosed to either of the Parties but also to all such
Claims of Reseller which are presently unknown, unanticipated and undisclosed
to either or both of the Parties and which may have arisen prior to the
Effective Date.

          (f)      REPRESENTATIONS. (i) Each Party represents, warrants and
agrees that in executing and entering into this Amendment, it is not relying
and has not relied upon any representation, promise or statement made by
anyone which is not recited, contained or embodied in this Amendment. Each
Party understands and expressly assumes the risk that any fact not recited,
contained or embodied herein or therein may turn out hereafter to be other
than, different from, or contrary to the facts now known to it or believed by
it to be true. Each Party further understands that the other Party may
possess material information regarding Claims that it has not shared or
revealed to the other Party. Nevertheless, Reseller intends by this
Amendment, and with the advice of its own independently selected counsel, to
release fully, finally and forever all Claims of Reseller and to agree that
this Amendment shall be effective in all respects notwithstanding any such
difference in facts, and shall not be subject to termination, modification or
rescission by reason of any such difference in facts.

                   (ii) Reseller represents and warrants that it has not
heretofore assigned or transferred or purported to assign or transfer to any
person or entity all or any part of or any interest in any Claim of Reseller.
Reseller agrees to indemnify and to hold harmless BA against any claim,
contention, demand, cause of action, obligation or liability of any nature,
character or description whatsoever, including the payment of attorneys' fees
and costs actually incurred, whether or not litigation is commenced, which
may be based upon or which may arise out of or in connection with any such
assignment or transfer or purported assignment or transfer of any Claim of
Reseller.

          (g)      NO LIABILITY. This Amendment is not intended to be and
shall not be deemed, construed or treated in any respect as an admission of
liability by any person or entity for any purpose.

          (h)      CONDITION PRECEDENT FOR BA ENTRY INTO AMENDMENT. The entry
by BA into this Amendment is premised, among other things, on BA not being
aware of having any Claims against Reseller or any affiliate of Reseller. As
such, to the extent that another reseller would wish to enter into an
arrangement with BA similar or identical to this Amendment, pursuant to
Section 252(i) of the TelAct or otherwise, BA would have no obligation to
enter into any such arrangement with such other reseller to

                                       18
<PAGE>

the extent that BA was aware of any Claims it might have against such other
reseller or any affiliate of such reseller.

          6.       FINAL AGREEMENT. This Amendment constitutes the full and
only agreement between the Parties with respect to its subject matter,
supersedes all previous agreements between them concerning such subject
matter and cannot be amended except by a writing duly signed by each of them.

          7.       AUTHORITY. Each of the Parties hereby covenants, warrants
and represents to the other Party that it has full power, right and authority
to execute, deliver, enter into and perform this Amendment.

          8.       CHOICE OF LAW. THIS AMENDMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK FOR
ALL PURPOSES, INCLUDING BOTH CONSTRUCTION AND REMEDY, WITHOUT REGARD TO
CHOICE OF LAW RULES (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL
OBLIGATIONS LAW (OR ANY SUCCESSOR PROVISION THERETO)).

          9.       JURISDICTION. The Parties hereby irrevocably submit to the
venue and to both subject matter and personal jurisdiction in the Courts of
the State of New York and of the United States of America for the Southern
District of New York.

          10.      COUNTERPARTS. This Amendment may be executed and delivered
in counterparts and may be delivered by facsimile transmission and shall be
binding upon each of the Parties and on their respective successors and
assigns.

          11.      HEADINGS. The headings contained in this Amendment are for
ease of reference only and shall be of no legal effect.

          12.      NO SEVERABILITY. If any of the provisions of this
Amendment are held to be invalid or unenforceable by a court or regulatory
authority of competent jurisdiction, BA may elect, at its sole option, to
terminate this Amendment or to enter into a mutually agreeable further
amendment to the Resale Agreements and/or agreement incorporating by
reference the terms of applicable BA resale tariffs (with respect only to
Reseller). In case of such termination, Reseller shall nonetheless remain
obligated to pay to BA all amounts, if any, due to BA pursuant to and, on
terms set forth in, this Amendment that have accrued as of the date of
termination.

          13.      TERMINATION RIGHT. BA is entering into this Amendment to
increase the volume of resale business it conducts with resellers, especially
in the short term. In addition, given that the procedures set forth herein
are new, the overall impact of such procedures on BA's business is uncertain.
Accordingly, BA is limiting the time period during which arrangements such as
those set forth in this Amendment shall be available. As such, if during the
period beginning on the date hereof and ending

                                       19
<PAGE>

November 30, 1999, Reseller shall not have placed its first order with BA for
an Eligible Service pursuant to the terms of this Amendment, BA may, at its
sole option, terminate this Amendment. In addition and, consistent with the
foregoing, to the extent that another reseller would wish to enter into an
arrangement with BA similar or identical to this Amendment, pursuant to
Section 252(i) of the TelAct or otherwise, BA would not be under any
obligation to enter into any such arrangement with such other reseller after
November 30, 1999.

          14.      MINIMUM VOLUME REPRESENTATION. Reseller represents and
warrants that, during the month immediately preceding the date hereof, it
purchased from BA, for resale, not less than 20,000 Qualified Business Lines.

          15.      RIGHT OF SETOFF. In addition to any other remedies
available to BA under the Resale Agreements, and/or applicable BA tariffs
and/or other contractual arrangements between BA and Reseller, if Reseller
does not pay to BA any amount due to BA under a Resale Agreement, and/or an
applicable BA tariff and/or other contractual arrangement between BA and
Reseller, BA may, at its sole option, set off such overdue amounts from the
amount of the Volume and Term Discount, Winback Discount, IntraLATA Toll
Discount and/or Existing Wholesale Discount.

          16.      BANKRUPTCY-RELATED PROVISIONS.

          (a)      PRE-PETITION WAIVER OF AUTOMATIC STAY. Reseller hereby
acknowledges and agrees that in the event it becomes the subject of a
bankruptcy, insolvency, liquidation or similar proceeding affecting the
rights of creditors under State or Federal law that it shall waive and shall
not assert or seek any automatic stay (including a stay imposed by operation
of 11 U.S.C. Sections 105, 362 or 366), injunction or similar bar on BA
exercising its rights or remedies available to it under any of the Resale
Agreements, this Amendment, applicable BA tariffs or applicable law,
including terminating any of the Resale Agreements and/or this Amendment,
terminating or curtailing service to Reseller or Reseller's customers,
transferring such customers to a new service provider, terminating any
license, possessory interest or lease arrangement or agreement with
Reseller, or repossessing any property owned by BA.

          (b)      ASSUMPTION OR REJECTION OF AGREEMENTS. In the event that a
case is commenced pursuant to 11 U.S.C. Section 101 ET SEQ. or similar Federal
or State insolvency law, by or against Reseller, Reseller agrees, within
thirty (30) days of such commencement, to elect either to assume or reject
the Resale Agreements (as amended hereby) and this Amendment and to file a
motion in its bankruptcy case and seek approval of such election within that
30-day time period.

          (c)      JURISDICTION TO MODIFY TERMS. Notwithstanding any other
provisions of this Amendment, any of the Resale Agreements or applicable BA
tariffs, this Amendment and the Resale Agreements are subject to change,
modification or cancellation as may be required by a regulatory authority or
court in the execution of its

                                       20
<PAGE>

lawful jurisdiction, other than a court exercising jurisdiction pursuant to
28 U.S.C. Section 1334.

          (d)      ACCELERATED BILLING. Reseller hereby acknowledges and
agrees that in the event it becomes the subject of a bankruptcy, insolvency,
liquidation or similar proceeding affecting the rights of creditors under
State or Federal law, BA may, at its option, bill Reseller for weekly service
charges under the Resale Agreements (as amended hereby) and/or applicable BA
tariffs, which amounts shall be due and payable within five (5) business days
of receipt by Reseller of the particular invoice.

          (e)      PREPAYMENT. Reseller hereby acknowledges and agrees that
in the event it becomes the subject of a bankruptcy, insolvency, liquidation
or similar proceeding affecting the rights of creditors under State or
Federal law, BA may, at its option, bill Reseller up to one (1) month in
advance of receipt by Reseller of BA services under the Resale Agreements (as
amended hereby) and/or applicable BA tariffs, and in such case Reseller shall
be required to prepay BA for such BA services, which amounts in respect
thereof shall be due and payable within five (5) business days of receipt by
Reseller of the particular invoice.

          17.      OTHER BA RESALE TERM AND VOLUME DISCOUNT PLANS. If BA
enters into, with a party other than Reseller, a resale term and volume
discount plan that contains terms and conditions that are materially
different than the terms and conditions set forth in this Amendment, upon
receipt of a written request from Reseller, BA agrees to promptly begin good
faith negotiations with Reseller in order to modify this Amendment or to
enter into a new contract with terms and conditions consistent with those in
the term and volume discount plan with the other party. In addition, upon
receipt of a written request from Reseller from time to time, BA shall inform
Reseller whether it has entered into any such other resale term and volume
discount plan and, if such plan is not subject to a non-disclosure
obligation, provide a copy of such plan to Reseller.

          18.      JOINT AND SEVERAL LIABILITY OF RESELLER COMPANIES. Each
Reseller Company (including all entities that become a Reseller Company)
shall be jointly and severally liable for any and all liabilities of any and
all Reseller Companies under this Amendment, the Resale Agreements, any other
resale agreements and related documents, applicable BA tariffs or otherwise;
provided, however, that for the avoidance of any doubt, the entry by Reseller
into this Amendment shall not be construed in any way as authorizing (or
requiring) Reseller to provide any telecommunications service.

          19.      LETTER OF CREDIT. Not later than the Effective Date of
this Amendment, Reseller shall obtain and provide to BA an unconditional,
irrevocable standby letter of credit naming BA as the beneficiary thereof and
otherwise in form and substance satisfactory to BA from a financial
institution acceptable to BA, in an amount equal to five hundred thousand
dollars ($500,000), in respect of charges (including, without limitation,
both recurring and non-recurring charges) for the services, facilities or

                                       21
<PAGE>

arrangements provided or to be provided by BA to Reseller (whether under any
Resale Agreement (as amended hereby), BA tariff or otherwise); provided,
however, that not later than one (1) year after the Effective Date of this
Amendment. Reseller shall increase the amount of such letter of credit to one
million dollars ($1,000,000); provided further that, not later than two (2)
years after the Effective Date of this Amendment, Reseller shall increase
the amount of such letter of credit to two million dollars ($2,000,000). BA
may (but is not obligated to) draw on the letter of credit upon notice to
Reseller in respect of any amounts billed to Reseller that are not paid
within the applicable time period for payment thereof. The fact that Reseller
provides the foregoing letter of credit shall in no way relieve Reseller from
compliance with BA's regulations as to advance payments and payment for
service, nor constitute a waiver or modification of the applicable terms of
the Resale Agreements, BA's tariffs or otherwise pertaining to the
discontinuance of service for nonpayment of any sums due to BA for the
services, facilities or arrangements rendered.

          IN WITNESS WHEREOF, the Parties have caused this Amendment to be duly
executed as of the day and year first above written.
