                     XDSL JOINT MARKET DEVELOPMENT AGREEMENT


       This SERVICES AGREEMENT (the "Agreement") is executed as of March 23,
1999, by and between NORTHPOINT COMMUNICATIONS, INC., a Delaware corporation
("NorthPoint"), and NETWORK PLUS, INC., a Massachusetts corporation ("Network
Plus").

                                        RECITALS

       WHEREAS, Network Plus is investing $2,500,000 in NorthPoint's Series D-1
Preferred Stock (the "Financing") under the terms set forth in the Series D-1
Preferred Stock Purchase Agreement; and

       WHEREAS, Network Plus desires to purchase xDSL products and services from
NorthPoint.

                                        AGREEMENT

       NOW, THEREFORE, in consideration of the promises and mutual covenants and
agreements hereunder contained, the parties hereto agree to the following terms
and conditions, which are in addition to the applicable terms and conditions for
NorthPoint's tariff for telecommunications services:

1.     PREFERRED STATUS. Network Plus will purchase all xDSL products and
       services from NorthPoint, and NorthPoint will provide all xDSL services
       and products requested by Network Plus, in each case unless (a) line
       orders cannot be served by NorthPoint's network footprint at the time the
       order is submitted, or (b) NorthPoint is unable to offer an xDSL-based
       product or service requested by a Network Plus end-user, and such product
       or service is offered by another xDSL provider in such end-user's market.
       This Agreement does not prevent Network Plus from providing xDSL services
       over its own xDSL facilities-based network.

2.     TERM. The term of this Agreement shall be two years from the date hereof.
       Thereafter, the Agreement shall continue on a month-to-month basis until
       terminated upon thirty (30) days prior written notice by either party
       hereto.

       the Securities and Exchange Commission. Asterisks denote omissions.


3.     PRICING.

       3.1    MONTHLY RECURRING CHARGES. Network Plus will receive the
              discounted xDSL products set forth in Appendix A at the prices set
              forth in Appendix A for line orders received by NorthPoint on or
              after the date hereof. Initially, the discounted rate shall be
              pursuant to the 10,000 line Ramp Schedule set forth on Appendix A.
              However, if Network Plus exceeds the line commitment level
              associated with the any greater line ramp schedule set forth in
              Appendix A in any quarter (such quarter defined as the relevant
              3-month period set forth on Appendix A), Network Plus will receive
              NorthPoint xDSL services at the discounts set forth in such
              greater line ramp schedule for the subsequent quarter. During each
              quarter thereafter, Network Plus shall receive discounts at the
              greater line ramp schedule so long as it meets the quarterly line
              commitments associated with the greater line ramp schedule. If
              Network Plus fails to meet the line levels associated with the
              greater line ramp schedule in any quarter, its discounts will be
              revised downward to the ramp schedule associated with its actual
              quarterly line installations. In no event shall Network Plus
              receive discounts less than those associated with the 10,000 line
              Ramp Schedule for products listed on Appendix A. Additionally, if
              NorthPoint decreases its standard pricing, then Network Plus'
              monthly recurring charge will be concurrently reduced.

       3.2    INSTALLATION CHARGE. Volume pricing applies only to xDSL monthly
              recurring charges. Standard prices will apply to installation and
              other applicable non-recurring charges.

       3.3    INTERCONNECTION CHARGE. The monthly interconnection charge will be
              [**] for each DS3. When Network Plus is collocated in the same
              site as NorthPoint's ATM packet-switch, the cross connect charge
              will be [**] per collocation DS3 port. Interconnection charges
              will be waived in each market until [**] Network Plus end-users
              are installed in such market, provided that such period of waiver
              shall not exceed six (6) months.

       3.4    MOST FAVORED NATIONS. The rates and charges for NorthPoint xDSL
              services set forth on Appendix A hereto shall be equal to or lower
              than the rates and charges imposed within NorthPoint's network
              footprint by NorthPoint on any of its customers for the same
              products or services in comparable or lesser quantities in
              comparable markets.

            Confidential Materials omitted and filed separately with
       the Securities and Exchange Commission. Asterisks denote omissions.


4.     LINE COMMITMENT. Network Plus will install a total of 10,000 lines by the
       end of the two-year term. An order for any product listed on Appendix A
       shall count as one installed line for purposes of this Section 4. Service
       orders for future NorthPoint xDSL business products will count towards
       Network Plus's line commitment on the same terms offered to similarly
       situated providers. The terms of the installation are set forth on
       Appendix B. A port reservation fee of [**] per line will be charged at
       the end of each year for each line less than the aggregate line
       commitment for that year, which shall be NorthPoint's sole remedy in the
       event that Network Plus fails to meet the line commitment set forth in
       this Section 4.

5.     MARKETING FUNDS.

       5.1    CO-MARKETING FUNDS. Network Plus is eligible to receive from
              NorthPoint (i) a "kick-start" launch fund of [**] as of the
              beginning of the first year of the two-year term for new market
              launches, and (ii) market development funds ("MDF") of [**] per
              new line installed. NorthPoint and Network Plus shall agree in
              writing as to the manner in which all of the above-mentioned
              co-marketing funds shall be spent prior to disbursement of such
              funds. Such funds will be subject to the co-marketing conditions
              and requirements of Appendix C hereto; provided that Network Plus
              shall, during the second year of the two-year term, match the
              funds granted pursuant to subsection (i).

       5.2    OTHER PROMOTIONS. Network Plus is not eligible for any other
              NorthPoint co-marketing fund programs other than those specified
              herein during the term of this Agreement.

6.     BRANDING. Network Plus may identify NorthPoint as its xDSL service
       provider and may include NorthPoint's logo on marketing and other
       materials promoting NorthPoint's and Network Plus's bundled xDSL
       services, but only where NorthPoint has approved such use in writing,
       which approval shall not be unreasonably withheld, and subject to the
       following: Network Plus shall use NorthPoint's logo subject to a
       non-exclusive, non-transferable license granted hereby. The use of
       NorthPoint's logo shall be in a manner and proper logo form as NorthPoint
       may direct from time to time. Network Plus will not make any deletions or
       additions to the logo, nor otherwise use the logo, except as specifically
       instructed by NorthPoint. Network Plus shall not use any other logo or
       trademark that could be confused with NorthPoint's logo or that may
       detract from the logo's distinctiveness and goodwill. Network Plus shall
       promptly report to NorthPoint any infringement of, imitation of or
       challenge to, the logo, of which Network Plus may become aware. Network
       Plus will provide all reasonable assistance (other than financial) as
       requested if

   4
            Confidential Materials omitted and filed separately with
       the Securities and Exchange Commission. Asterisks denote omissions.


       NorthPoint commences or defends any action relating to Network Plus' use
       of NorthPoint's logo, provided that Network Plus shall receive reasonable
       compensation for such assistance, including out-of-pocket costs. Network
       Plus will use reasonable efforts to maintain the goodwill associated with
       NorthPoint's logo.

7.     PERFORMANCE REQUIREMENTS. NorthPoint will provide its services in the
       manner set forth in Appendix B. Network Plus understands that certain
       performance requirements are affected by Local Exchange Carrier (LEC)
       policies and practices. To the extent that Network Plus has notified
       NorthPoint of any failure to meet agreed performance requirements
       (excluding any and all failures arising from end-user or Network Plus
       delays) that materially affect Network Plus's ability to install
       end-users, and NorthPoint fails to correct such identified problems by a
       mutually agreed date (the "Repair Date"), Network Plus will be relieved
       of its line commitment obligations under Section 4 for those
       materially-affected orders from the Repair Date until the date upon which
       NorthPoint corrects the identified problems.

8.     PRODUCT DEVELOPMENT. Network Plus may make recommendations to NorthPoint
       regarding products that Network Plus would like NorthPoint to develop.
       NorthPoint will make a good faith determination as to whether development
       of such a product would be a commercially viable opportunity that is
       consistent with NorthPoint's business goals. NorthPoint may, if it is
       considering developing such a product, require that Network Plus commit
       to purchasing a certain volume of such product, the specific terms of
       which would be mutually agreed upon by the parties at such time.

9.     MISCELLANEOUS.

       9.1    TERMINATION. Upon termination of this Agreement by either party,
              NorthPoint will complete provisioning of all lines ordered prior
              to the termination date and will maintain all of the Network Plus
              and end-user xDSL lines for the remainder of the term of each
              particular service order. During the time that any service orders
              remain in effect, Network Plus will continue to pay all monthly
              charges for the lines that were installed pursuant to such service
              orders. Network Plus shall not actively cause any xDSL lines to be
              disconnected and reconnected to any other competitive xDSL
              provider for a period of one year after the termination of this
              Agreement. Network Plus will pay a one-time disconnection fee of
              [**] per line for all lines disconnected and reconnected to other
              competitive xDSL providers within [**] of the termination of this
              Agreement. For the purposes of this Agreement, Network Plus shall
              not be considered a competitive xDSL provider.

            Confidential Materials omitted and filed separately with
       the Securities and Exchange Commission. Asterisks denote omissions.


              This Section 9.1 shall not cause Network Plus to incur a
              disconnection fee when the end-user is moved to Network Plus' xDSL
              network.

       9.2    NO THIRD PARTY BENEFICIARIES. Except as specifically provided
              herein, this Agreement does not provide and shall not be construed
              to provide third parties, including any customer, with any remedy,
              claim, and cause of action or privilege. The parties specifically
              acknowledge and agree that either party's operating subsidiaries
              shall be entitled to order and provision xDSL lines on the terms
              and conditions hereunder, and, as such, are intended third party
              beneficiaries of the rights under this Agreement; provided
              however, that such third party beneficiaries shall agree in
              writing to be bound by the terms of this Agreement.

       9.3    FORCE MAJEURE. Neither party shall be responsible for any failure
              to perform any obligation or provide service hereunder because of
              any (i) act of God, (ii) war, riot or civil commotion, (iii)
              governmental acts or directives, strikes, work stoppage, or
              equipment or facilities shortages, in any such case which are
              being experienced by providers of telecommunications services
              generally and not targeted or directed at NorthPoint specifically,
              or (iv) other similar force beyond such party's reasonable
              control.

       9.4    INDEMNIFICATION. Each party hereto shall indemnify the other party
              and its affiliates and their respective representatives, in their
              capacities as such, and their respective successors, assigns,
              heirs and personal representatives (collectively, "Indemnified
              Parties") against and hold each of them harmless from any and all
              damage, claim, action, suit, proceeding, judgment, loss,
              liability, cost and expense (including reasonable expenses of
              investigation and attorneys' fees and expenses as incurred)
              incurred or suffered by any Indemnified Party arising out of or
              relating to any breach of any covenant or agreement of the other
              party contained herein or in any other agreement executed in
              connection herewith.

       9.5    LIMITED LIABILITY. In no event will either party hereto and/or any
              of its affiliates be liable to or through the other party for any
              of the following: (i) damages caused by the other party's and/or
              any of its affiliates' failure to perform their obligations and
              responsibilities; (ii) claims or demands brought against the other
              party by third parties, other than those third party claims in
              respect of which such party is expressly obligated to indemnify
              the other party pursuant to a provision of this agreement; or
              (iii) except as otherwise set forth herein, any lost profits, loss
              of business, loss of use (or interruptions of business), lost
              savings, lost opportunities or other consequential, special,
              incidental, indirect, exemplary or punitive damages, any or all of
              which arise from or in connection with the delivery, use, or
              performance of service governed

              by this Agreement, even if a party and/or any of its affiliates
              has been advised of the possibility of such loss.

       9.6    FURTHER ASSURANCES. Each party hereto shall execute and/or cause
              to be delivered to each other party hereto such instruments and
              other documents, and shall take such other actions, as such other
              party may reasonably request for the purpose of carrying out or
              evidencing any of the transactions contemplated by this Agreement.

       9.7    ENTIRE AGREEMENT; AMENDMENT IN WRITING; SEVERABILITY. This
              Agreement, which includes the Exhibits, Schedules, Appendices and
              other agreements expressly referenced herein, constitutes the
              entire agreement between the parties concerning the subject matter
              hereof and supersedes any prior agreement, representations,
              statements, negotiations, understandings, proposals or
              undertakings, oral or written, with respect to the subject matter
              expressly set forth herein. Any amendment or supplement to this
              Agreement shall be in writing and duly executed by both parties.
              If any provision of this Agreement shall be held to be illegal,
              invalid or unenforceable, each party agrees that such provision
              shall be enforced to the maximum extent permissible so as to
              effect the intent of the parties, and the validity, legality and
              enforceability of the remaining provisions of this Agreement shall
              not in any way be affected or impaired thereby. If necessary to
              effect the intent of the parties, the parties shall negotiate in
              good faith to amend this Agreement to replace the unenforceable
              language with enforceable language that reflects such intent as
              closely as possible.

       9.8    EXPENSES. Each party shall pay all costs and expenses that it
              incurs with respect to the negotiation, execution, delivery and
              performance of this Agreement.

       9.9    ATTORNEY'S FEES. If any legal action or other legal proceeding
              (including arbitration) relating to the transactions under this
              Agreement or the enforcement of any provision of this Agreement is
              brought against any party hereto, the prevailing party shall be
              entitled to recover reasonable attorneys' fees, costs and
              disbursements (in addition to any other relief to which the
              prevailing party may be entitled).

       9.10   CHOICE OF LAW; VENUE; JURY TRIAL.

               9.10.1   This Agreement is to be construed in accordance with and
                        governed by the internal laws of the State of New York
                        without giving effect to choice of law.

               9.10.2   Each of the parties hereto irrevocably waives the right
                        to a jury trial in connection with any legal proceeding
                        relating to

                     Agreement.

       9.11   NOTICES. All notices or other communications required or permitted
              to be delivered to any party under this Agreement shall be in
              writing and shall be sent by registered or certified mail, by

       9.12   ASSIGNMENT. The provisions of this Agreement shall inure to the
              benefit of, and be binding upon, the successors and permitted
              assigns of the parties hereto. Upon prior written notice, either
              party may assign or transfer its rights or obligations under this
              Agreement to any third party.

       9.13   CONFIDENTIALITY; PUBLICITY. The parties acknowledge and agree that
              the Mutual Non-Disclosure Agreement between them, dated
              _______________, 199__, remains in full force and effect between
              the parties. In addition, neither party hereto will (i) provide
              billing detail, invoice information or any other information to
              any third party that will enable such third party or another party
              to determine the prices that either NorthPoint or Network Plus

              any other way to its customers, end-users, channels, partners or
              any third party the prices or other terms that either NorthPoint
              or Network Plus will receive under any agreement between such
              parties. Any disclosure required under any state or federal law or
              regulation shall be exempt from this provision, so long as the
              revealing party shall provide the other party with written notice
              of such proposed disclosure. Subject to the foregoing, any public
              disclosure of this Agreement and the parties' respective
              relationships shall require written pre-approval from the other
              party, such approval not to be unreasonably withheld.

       9.14   COUNTERPARTS. This Agreement may be executed in any number of
              counterparts, each of which shall be an original, but all of which
              together shall constitute one instrument.

       9.15   HEADINGS. The headings contained in this Agreement are for
              convenience of reference only, shall not be deemed to be a part of
