                     AGREEMENT FOR IT TRANSITION SERVICES

This Agreement for IT Transition Services is made between GTE Service
Corporation, a New York corporation, with offices at 1255 Corporate Drive,
Irving, Texas 75038 and its affiliates (individually and collectively "GTE") on
one hand, each only with respect to the Services (defined below) it provides,
and Genuity Solutions Inc., a Delaware corporation, with offices at 3 Van de
Graaff Drive, Burlington, Massachusetts 01803 ("GENUITY"), and its subsidiaries
and successors in interest, on the other hand.

Whereas, GENUITY and GTE each will procure from the other under this Agreement
information technology services, with the services defined in individual
Statements of Work, and the ownership and rights in intellectual property
deliverables defined in the Statements of Work being apportioned between the
parties. In consideration of the mutual terms and conditions of this Agreement,
the parties agree as follows:

1.   GENERAL.

     (a)  Services. Each of GTE and GENUITY (each a "Service Recipient", as the
          --------
          case may be) desires to obtain certain information technology
          transitional services on a non-exclusive basis from the other party
          hereto or one of its affiliate companies (each a "Service Provider",
          as the case may be) under the terms and conditions of this agreement
          and statements of work ("Statements of Work") entered into by the
          parties (this agreement and all attached Statements of Work are
          collectively referred to as the "Agreement"), and Service Provider
          shall provide to Service Recipient such information technology
          transitional services (individually and collectively, "Services"). If
          there is any conflict or inconsistency between the terms and
          conditions of a Statement of Work and the terms and conditions of this
          Agreement (excluding for this purpose the Statements of Work), the
          terms and conditions of the Statement of Work shall control.

     (b)  Statements of Work - Generally. Each of the Statements of Work entered
          ------------------------------
          into by the parties shall: (i) refer expressly to this Agreement; (ii)
          designate the date as of which the provisions of the Statement of Work
          shall be effective and, if applicable, the term or period of time
          during which Service Provider shall perform Services, provide
          resources or otherwise discharge its obligations as specified in the
          Statement of Work if different from the term set out in this Agreement
          (excluding for this purpose the Statement of Work); (iii) describe the
          Services to be performed, Work Product (as defined herein) to be
          delivered, resources to be provided or obligations to be discharged by
          Service Provider pursuant to the Statement of Work; (iv) describe the
          obligations of Service Recipient related to the Statement of Work,
          including any facilities, equipment,

                                       1
<PAGE>

          personnel and tasks or other support to be provided or performed by
          Service Recipient; (v) specify the payments to be made to Service
          Provider under the Statement of Work, or, if applicable, the basis on
          which such payments shall be computed; and (vi) specify any other
          terms and conditions appropriate to the Services to be performed and
          the obligations of the parties. If there is any conflict or
          inconsistency between the terms and conditions of a Statement of Work
          and the terms and conditions of this Agreement (excluding for this
          purpose the Statement of Work), the terms and conditions of the
          Statement of Work shall control. Service Recipient may request
          services through a letter, email, or other written or electronic
          medium. The request for services will outline the nature and scope of
          the services requested. Within thirty (30) days after receipt of the
          request for services, Service Provider shall provide a high-level
          estimate of the activities to be performed along with an estimate of
          the number of hours required to perform each of the activities.
          Preparation of the high level estimate shall be charged at the hourly
          rates then in effect between Service Provider and Service Recipient,
          or if no rate is specified, at Service Provider's then-current rate
          for such activity. Service Recipient shall have thirty (30) days to
          notify Service Provider if Service Recipient desires Service Provider
          to prepare a Statement of Work. Unless otherwise specified in a
          particular Statement of Work, the Statement of Work shall be issued on
          a time and materials basis and shall include an estimate of the hours
          needed to complete the Statement of Work and the hourly rates
          applicable to the services being provided. All services are
          contemplated to be performed at Service Provider's location during
          normal business hours, excluding weekends and Service Provider's
          holidays. If a Statement of Work requires travel to Service
          Recipient's location or another location at the request of Service
          Recipient, Service Provider shall bill travel time incurred by Service
          Provider's employees at the hourly rate(s) specified in the Statement
          of Work. Service Provider shall issue an invoice monthly for such
          services in accordance with this Agreement. For any Statement of Work
          for which GTE's GTEDS affiliate is a Service Provider hereunder, the
          terms and conditions contained in Attachments 1 and 2, entitled
          "Service Level Agreement for Application Enhancement and Development"
          and "SAP R/3 Service Level Agreement", respectively, shall apply to
          such Statement of Work.

     (c)  Order of Precedence. In the event of any conflict or inconsistency
          -------------------
          between the terms and conditions of any Statement of Work, this
          Agreement, the Software License Agreement among the parties and of
          even date hereof, the Software Development and Technical Services
          Agreement among the parties and of even date hereof, the Intellectual
          Property Ownership and Cross License Agreement among the parties and
          of even date hereof, and any other agreement among the parties hereof,
          the terms and conditions shall take precedence in the following order:

                                       2
<PAGE>

          (i)   Statement of Work;

          (ii)  This Agreement (excluding for this purpose the Statements of
                Work);

          (iii) Software License Agreement or the applicable software license
                agreement which is directed to the software for which the
                Services are provided; and

          (iv)  Software Development and Technical Services Agreement.

     (d)  Milestones, Phases and Timing; Changes. Each of the Statements of Work
          --------------------------------------
          shall set out, if applicable, milestones and phases of the work. When
          phases are specified, Service Provider shall not be obligated to
          proceed with work on the next phase until Service Recipient has
          provided written authorization to proceed. If Service Recipient has
          not provided Service Provider with written authorization to proceed on
          a specific phase, and it is necessary to commence or complete such
          phase in order to meet any milestones specified in the Statement of
          Work, Service Provider shall not have any obligations with respect to
          such milestones and the Statement of Work shall be deemed to be
          modified accordingly. The Statement of Work may be modified by mutual
          written agreement, signed by both parties. No verbal changes to the
          Statement of Work are permitted.

     (e)  Performance. All Services shall be performed in accordance with the
          -----------
          terms and conditions of this Agreement and the requirements, order of
          performance and delivery dates specified in each Statement of Work.
          Service Provider shall devote such time, efforts and resources to the
          performance of Services as are necessary to accomplish the tasks
          specified in any Statement of Work. The Service Provider may call upon
          the expertise and/or assistance of its affiliates, subcontractors or
          consultants in the performance of such Services, provided that Service
          Provider shall obtain the prior written consent of Service Recipient
          in the event it desires to use outside subcontractors or consultants.
          If a Statement of Work specifies that some or all of the work will be
          done by a subcontractors or consultant, no additional approval shall
          be required.

     (f)  Third Party Software Licenses. The Service Recipient acknowledges that
          -----------------------------
          Service Provider and its affiliates may be required to use certain
          software licensed to GTE by third parties to provide Services pursuant
          to this Agreement. If any licensor of such third party software
          requires the payment of any consideration to permit Service Provider
          to use the vendor's software in order to perform its obligations under
          this Agreement,

                                       3
<PAGE>

          Service Provider shall provide Service Recipient with thirty (30) days
          prior written notice of such additional consideration. Service
          Recipient shall have the option to (i) procure its own license to such
          software at its own expense, or (ii) authorize Service Provider to
          incur such required additional consideration on its behalf and at
          Service Recipient's expense. In the event that Service Recipient does
          not agree to either (i) or (ii) above, Service Provider shall not be
          required to provide the Services for which such third party licenses
          are required. If the third party requires Service Recipient to secure
          rights in such third party software to receive the Services or to use
          the result of such Services, Service Recipient shall be responsible
          for securing such rights at its own cost and expense.

     (g)  Service Recipient Provided Software. If Service Recipient elects to
          -----------------------------------
          use Service Provider Hardware (as defined below) to operate and run
          Service Recipient Provided Software (also as defined below) pursuant
          to a Statement of Work, Service Recipient shall obtain all licenses
          necessary for use of such software, pay any associated fees negotiated
          with Service Provider for running such software for Service Recipient
          and pay any costs related to obtaining required consents needed by
          Service Provider to use such software for Service Recipient's benefit.
          Service Recipient shall be responsible for all costs associated with
          Service Recipient provided third party software. Service Recipient
          agrees to indemnify and hold Service Provider harmless against any
          loss, cost, claim, liability, damage, expense (including reasonable
          attorney's fees), or demand by or on behalf of any person, firm,
          corporation, or governmental authority resulting from or arising out
          of Service Recipient's alleged violation of such third party software
          rights, provided that prior to agreement on a Statement of Work, the
          parties shall have worked diligently together to identify all license
          rights needed by Service Recipient hereunder and to confirm that
          Service Provider has the right to perform the services hereunder.
          "Service Provider Hardware" shall mean the central processing units
          and peripheral equipment installed in a Service Provider's facility
          and utilized by Service Provider to provide Services described in any
          Statement of Work. The term Service Provider Hardware does not include
          circuit equipment from Service Recipient's site to Service Provider's
          facility, terminals, controllers, or telecommunications equipment at
          Service Recipient's site(s) required to enable Service Recipient to
          utilize Service Provider's Services, all of which are Service
          Recipient's responsibility. "Service Recipient Provided Software"
          shall mean software owned or licensed by Service Recipient which is
          installed an operated at a Service Provider facility pursuant to a
          Statement of Work.

2.   COMPENSATION AND BILLING.

     (a)  Invoices. The charges for the Services shall be set out in the
          --------
          applicable Statement of Work. Service Provider shall invoice Service
          Recipient for Services in accordance with the payment schedule set
          forth in the applicable Statement of Work. Each invoice shall
          reference this Agreement and the applicable Statement of Work. The
          invoices shall be itemized to show the details as to all billed items.
          Payments shall be made within thirty (30) days from the date each
          invoice is received by Service Recipient.

     (b)  Sales, Use and Other Taxes. In addition to the charges for Services,
          --------------------------
          Service Recipient shall pay Service Provider an amount equal to any
          sales, use, privilege, gross revenue, excise, or any other tax (except
          income and franchise taxes), as well as any assessments or duties with
          respect to the Services lawfully levied by a duly constituted
          governmental authority and for which Service Provider is required, by
          law, to collect from Service Recipient. In addition each party shall
          be responsible for all real and personal property taxes imposed on
          software and equipment owned by the respective parties on January 1 of
          every year. If Service Recipient determines that any Services are
          exempt from a tax, Service Recipient must provide Service Provider a
          properly completed exemption certificate, for each jurisdiction for
          which Service Recipient is claiming an exemption, before Service
          Provider will exclude the respective tax from amounts charged to
          Service Recipient. Service Recipient will not deduct any tax amount
          from remittances to Service Provider until a properly completed
          exemption certificate, for all jurisdictions for which Service
          Recipient is claiming an exemption, has been provided to Service
          Provider.

     (c)  Expense Reimbursement. Service Recipient shall reimburse Service
          ---------------------
          Provider for reasonable expenses for travel, meals and lodging
          incurred by Service Provider in the performance of its obligations
          under this Agreement. Any such charges shall be in compliance with
          Service Provider's employee expense policies. There shall be no mark-
          up of such expense charges. Service Provider shall maintain
          documentation of expenses incurred, and shall provide copies of
          invoices of $100 or more upon Service Recipient's request. Service
          Provider shall bill Service Recipient monthly for expenses as they
          accrue. The parties will specify any limitation on the reimbursement
          of expenses in the applicable Statement of Work. It is acknowledged
          and agreed that if Service Provider is reasonably required to incur
          expenses beyond such limitation in order to provide the Services, then
          Service Provider is excused from performing such Services until said
          expense limitation is removed or changed as mutually agreed, provided
          that Service Provider promptly notifies Service Recipient of the need
          to exceed the limitation.

                                       5

     (d)  Records. Service Provider shall maintain complete and accurate records
          -------
          in a form consistent with generally accepted accounting practices, to
          substantiate Service Provider charges. Service Provider shall retain,
          and make available upon request, such records for a period of three
          (3) years from the date of invoice for Services. Service Recipient and
          its authorized agents, subject to obligations of confidentiality as
          set forth in this Agreement, shall have access to such records upon
          prior written request during normal business hours during the term of
          this Agreement and during the respective periods in which Service
          Provider is required to maintain such records pursuant to this
          subsection 2(d). Access to the records shall be made at the location
          where such records are normally maintained.

     (e)  Late Payment. Late payment charges may be imposed by Service Provider
          ------------
          at the rate of 1 1/2% per month (18%) per year). Interest shall not be
          payable by Service Recipient for amounts on invoices which it has
          disputed in good faith provided that Service Recipient pays the
          applicable amount due, if any, within thirty (30) days of the
          resolution of the dispute. With respect to disputed invoices,
          undisputed amounts must be paid within thirty (30) days from the date
          of the invoice. Service Provider must be advised in writing of any
          amounts disputed by Service Recipient and the basis for the dispute
          within ten (10) days from the date of the invoice or the entire
          invoice must be paid.

3.   TERM.

     This Agreement is effective as of the date of closing of the initial public
     offering of Genuity Inc. shares of stock ("Effective Date") and shall
     expire the earlier of: (a) one (1) year after the Effective Date or (b)
     expiration or termination of all of the Statements of Work under this
     Agreement unless earlier terminated under Section 24(a), (b) or (c) of this
     Agreement. In the event of any termination or expiration, Genuity agrees to
     reasonably cooperate in transitioning the work to any successor service
     provider, and upon GTE's request and at its expense, Genuity shall use
     commercially reasonable efforts to secure GTE's continued use of applicable
     third party licenses. GTE shall use its best efforts to provide all items,
     services and personnel necessary to effectuate and ensure a smooth and
     timely transition for Genuity from dependence on Services under each
     Statement of Work to standalone ability to perform such Services itself or
     in conjunction with third parties. Both parties shall make appropriate
     resources available in connection with such transition, and any such steps
     taken by GTE shall be accomplished prior to the expiration of the term of
     this Agreement.

4.   ACCEPTANCE.

     (a)  Acceptance. Each Statement of Work shall specify the criteria, if any,
          ----------
          that Service Provider must meet in order for the Work Products
          described in the Statement of Work to be accepted by Service
          Recipient. It may also specify a test plan, and such other information
          as Service Provider and Service Recipient mutually deem appropriate
          and the period of time, if any, that Service Recipient shall have to
          review such Work Product and provide notice of acceptance or rejection
          to Service Provider. Failure to accept or reject such Work Product
          within the specified period of time or the commercial use of such Work
          Product by or for the benefit of Service Recipient shall be deemed to
          be acceptance.

     (b)  Rejection and Revision. If Service Recipient rejects any Work Product,
          ----------------------
          it shall specify in reasonable detail in writing the reasons for
          rejection and the requirements for revision. If the notice of
          rejection is not sufficiently detailed to allow Service Provider to
          determine why such Work Product is unacceptable, Service Provider may
          request in writing that Service Recipient provide sufficient
          additional information. If Service Provider and Service Recipient have
          joint responsibility for the Work Product and the Work Product
          requires revision, Service Provider shall assist Service Recipient in
          making revisions necessary for the Work Product to meet the acceptance
          criteria within a period of time that is reasonable under the
          circumstances. If Service Provider has sole responsibility for the
          Work Product, then it shall make the necessary revisions within a
          period of time that is reasonable under the circumstances.

5.   CONFIDENTIAL INFORMATION.

     (a)  Confidentiality. In the course of requesting and performing Services
          ---------------
          pursuant to this Agreement, each party may receive or acquire from the

          sketches, models, samples, computer programs, methods, concepts, know-
          how, techniques, processes, and other technical or business
          information that the other party desires to protect against
          unauthorized use or further disclosure. Unless otherwise expressly set
          forth in a Statement of Work, for purposes of this Agreement,

          or in the applicable Statement of Work; or (iv) information orally
          disclosed and identified as confidential at the time of such
          disclosure which is summarized in writing within thirty (30) days of
          such disclosure. Each party shall remain the exclusive owner of its
          Confidential Information.

     (a)  Use of Confidential Information. The Confidential Information of the
          -------------------------------
          disclosing party may be used by the receiving party only for the
          performance or use of Services or Work Products to be provided
          pursuant to this Agreement and may only be disclosed to those
          employees, subcontractors or agents of the receiving party who have a
          need to know in order to perform or use Services or Work Products
          pursuant to this Agreement. Except and to the extent set forth in
          subsection 6(c), the receiving party may not disclose Confidential
          Information of the other party to any other person, entity, or the
          public without the prior written consent of the disclosing party.
          However, such Confidential Information may be disclosed by the
          receiving party without the necessity of prior written consent, to the
          receiving party's subcontractors or consultants who require access to
          such Confidential Information to perform or use the Services under
          this Agreement, provided such persons have entered into written
          agreements which contain obligations of nondisclosure and nonuse no
          less restrictive than set forth in this Section 6. It is agreed that
          such written agreements shall be enforceable by the disclosing party.

     (b)  Exceptions. The obligations in subsection 6(b) shall not apply to that
          ----------
          portion of any information received from the disclosing party which
          is: lawfully in the receiving party's possession, with no restriction
          on use or disclosure, prior to its acquisition from the disclosing
          party; received in good faith by the receiving party, with no
          restrictions on use or disclosure, from a third party not subject to
          any confidential obligation to the disclosing party; now or later
          becomes publicly known through no breach of confidential obligation by
          the receiving party; released by the disclosing party to any other
          person, firm or entity (including governmental agencies or bureaus)
          without restriction on use or disclosure; or independently developed
          by or for the receiving party without any reliance on or use of
          Confidential Information of the disclosing party. The foregoing
          exceptions shall not apply to software in any form.

     (d)  Disclosure and Notification. If a receiving party receives a request
          ---------------------------
          to disclose any Confidential Information of the disclosing party
          (whether pursuant to a subpoena, an order issued by a court or other
          governmental authority of competent jurisdiction or otherwise) and, on
          advice of legal counsel, determines that disclosure is required under
          applicable law, the receiving party agrees that, prior to disclosing
          any Confidential Information of the disclosing party, it shall (i)
          notify the disclosing party of the

          existence and terms of such request or advice, (ii) cooperate with the
          disclosing party in taking legally available steps to resist or narrow
          any such request or to otherwise eliminate the need for such
          disclosure at the disclosing party's sole expense, if requested to do
          so by the disclosing party, and (iii) if disclosure is required, it
          shall be the obligation of the disclosing party to use its
          commercially reasonable efforts to obtain a protective order or other
          reliable assurance that confidential treatment shall be afforded to
          such portion of the Confidential Information of the disclosing party
          as is required to be disclosed.

     (e)  Continuing Obligation. The obligation of non-disclosure and non-use
          ---------------------
          with respect to Confidential Information of the disclosing party shall
          survive termination of this Agreement and shall continue for a period
          of 5 years thereafter, provided that the obligations of non-disclosure
          and non-use shall continue in perpetuity for software included in
          Confidential Information.

          with those terms and conditions being applied to any Statement of Work
          issued hereunder and being incorporated herein in their entirety by

               Agreement, with such terms and conditions being incorporated
               herein in their entirety by this reference.

7.   DISPUTE RESOLUTION.

     (a)  General. Except as provided in subsection 7(d) below, any controversy
          -------
          or claim arising out of or relating to this Agreement, or the breach
          thereof, shall attempt to be settled first, by good faith efforts of
          the parties to reach mutual agreement, and second, if mutual agreement
          is not reached to resolve the dispute, by final, binding arbitration
          as set out in subsection 7(c) below.

     (b)  Initial Resolution. A party that wishes to initiate the dispute
          ------------------

          resolution procedures. Each party shall appoint a knowledgeable,
          responsible representative from the company who has the authority to
          settle the dispute, to meet and negotiate in good faith to resolve the
          dispute. The discussions shall be left to the discretion of the
          representatives, who may utilize other alternative dispute resolution
          procedures such as mediation to assist in the negotiations.
          Discussions and correspondence among the representatives for purposes
          of these negotiations shall be treated as Confidential Information
          developed for purposes of settlement, shall be exempt from discovery
          and production, and shall not be admissible in the arbitration
          described above or in any lawsuit pursuant to Rule 408 of the Federal
          Rules of Evidence. Documents identified in or provided with such
          communications, which are not prepared for purposes of the
          negotiations, are not so exempted and may, if otherwise admissible, be
          admitted in evidence in the arbitration or lawsuit. The parties agree
          to pursue resolution under this subsection 7(b) for a minimum of sixty
          (60) days before requesting arbitration.

     (c)  Arbitration. If the dispute is not resolved under the preceding
          -----------
          subsection 7(b) within sixty (60) days of the initial written notice,
          either party may demand arbitration by sending written notice to the
          other party. The parties shall promptly submit the dispute to the
          American Arbitration Association for resolution by a single neutral
          arbitrator acceptable to both parties, as selected under the rules of
          the American Arbitration Association. The dispute shall then be
          administered according to the American Arbitration Association's
          Commercial Arbitration Rules, with the following modifications: (i)
          the arbitration shall be held in a location mutually acceptable to the
          parties, and if the parties do not agree, the location shall be New
          York City; (ii) the arbitrator shall be licensed to practice law;
          (iii) the arbitrator shall conduct the arbitration as if it were a

                                      10
<PAGE>

          bench trial and shall use, apply and enforce the Federal Rules of
          Evidence and Federal Rules of Civil Procedure; (iv) except for
          breaches related to Confidential Information, the arbitrator shall
          have no power or authority to make any award that provides for
          consequential, punitive or exemplary damages; (v) the arbitrator shall
          control the scheduling so that the hearing is completed no later than
          60 days after the date of the demand for arbitration; and (vi) the
          arbitrator's decision shall be given within 5 days thereafter in
          summary form that states the award, without written decision, which
          shall follow the plain meaning of this Agreement, the relevant
          documents, and the intent of the parties. Judgment on the award
          rendered by the arbitrator may be entered in any court having
          jurisdiction over the parties. Each party to the dispute shall bear
          its own expenses arising out of the arbitration, except that the
          expenses of the facilities to conduct the arbitration and the fees of
          the arbitrator shall be shared equally by the parties.

     (d)  Injunctive Relief. The foregoing notwithstanding, each party shall
          -----------------
          have the right to seek injunctive relief in an applicable court of law
          or equity independent of any resolution of the dispute in accordance
          with the foregoing.

8.   RELATIONSHIP OF PARTIES.

     (a)  Independent Contractors. In providing any Services pursuant to this
          -----------------------
          Agreement, Service Provider and its affiliates are independent
          contractors and not agents or representatives of Service Recipient.
          Persons furnished by the respective parties shall be solely the
          employees or agents of such parties, respectively, and shall be under
          the sole and exclusive direction and control of such parties. They
          shall not be considered employees of the other party or parties for
          any purpose. Each party shall also be responsible, respectively, for
          payment of taxes, including federal, state, and municipal taxes,
          chargeable or assessed with respect to its employees or agents, such
          as social security, unemployment, worker's compensation, disability
          insurance and federal and state income tax withholding.

     (b)  No Performance. Neither party undertakes by this Agreement or any
          --------------
          Statement of Work to conduct the business or operations of the other
          party. Nothing contained in this Agreement or any Statement of Work is
          intended to give rise to a partnership or joint venture between the
          parties or to impose upon the parties any of the duties or
          responsibilities of partners or joint venturers.

                                      11
<PAGE>

9.   FORCE MAJEURE.

     If performance of any Services under this Agreement is prevented,
     restricted or interfered with by reason of acts of God, wars, revolution,
     civil commotion, acts of public enemy, embargo, acts of government in its
     sovereign capacity, labor difficulties, including without limitation,
     strikes, slowdowns, picketing or boycotts, communication line failures,
     power failures, or any other circumstances beyond the reasonable control
     and not involving any fault or negligence of the party affected, the party
     affected, upon giving prompt notice to the other party, shall be excused
     from such performance on a day-to-day basis during the continuance of such
     prevention, restriction, or interference (and the other party shall
     likewise be excused on a day-to-day basis during the same period, from
     performance of its obligations which are dependent upon or affected by such
     nonperformance), provided, however, that the party so affected shall use
     its commercially reasonable efforts to avoid or remove such causes of
     nonperformance and both parties shall proceed immediately with the
     performance of their obligations under this Agreement whenever such causes
     are removed or cease. If a force majeure condition continues to prevent a
     party from performing for more than (30) consecutive days, then the other
     party may terminate the applicable Statement of Work.

10.  REGULATORY COMPLIANCE.

     (a)  Cooperation. This Agreement is subject at all times to any statute,
          -----------
          order, rule, or regulation or any state or federal regulatory agency
          having competent jurisdiction over one or both of the parties hereto
          or the Services provided hereby. The parties agree to cooperate with
          each other and with any applicable regulatory agency so that any and
          all necessary approvals may be obtained. During the term of this
          Agreement, the parties agree to continue to cooperate with each other
          in any review of this Agreement by a regulatory agency so that the
          benefits of this Agreement may be achieved.

     (b)  Filing Agreement. Notwithstanding the effective date and term of this
          ----------------
          Agreement as stated elsewhere, to the extent that any statute, order,
          rule or regulation or any regulatory agency having competent
          jurisdiction over one or both parties to this Agreement, shall require
          that this Agreement or subsequent amendment be filed with or approved
          by such regulatory agency before the Agreement or amendment may be
          effective, this Agreement or amendment shall not be effective in such
          jurisdiction until the first business day after such approval or
          filing shall have occurred.

                                       12

11.  INDEMNIFICATION.

     (a)  General. GTE and GENUITY, to the fullest extent permitted by law, each
          -------
          shall defend, indemnify and hold harmless the other and its
          affiliates, officers, agents and employees from any and all amounts
          payable under any judgment, verdict, court order or settlement (and
          associated fees and disbursements of counsel) arising from or related
          to any third-party claims for injury, sickness, disease or death of
          any person or damage to any real or tangible personal property or
          assets to the extent arising from the indemnitor's (either directly or
          through its officers, agents, subcontractors or representatives)
          negligence or willful misconduct in the performance of this Agreement
          provided, however, that if a claim is the result of the joint
          negligence or joint willful misconduct of GTE and GENUITY, the amount
          of the claim for which each party is entitled to indemnification shall
          be limited to that portion of such claim that is attributable to the
          negligence or willful misconduct of the indemnifying party. The
          parties agree that the price for Services provided under this
          Agreement includes consideration for the obligation to indemnify as
          set out in this subsection 13(a).

     (b)  Losses. GENUITY and GTE each shall be responsible for any and all
          ------
          claims, actions, damages, liabilities, costs and expenses, including
          reasonable attorneys' fees and expenses (collectively, "Losses"), to
          their respective tangible personal or real property (whether owned or
          leased), and each party agrees to look only to its own insuring
          arrangements (if any) with respect to such Losses. Subject to the
          procedures set forth below, each party shall indemnify, defend, and
          hold the other party harmless from any and all Losses arising out of,
          under or in connection with claims for which the indemnitor is
          responsible under the preceding sentence.

     (c)  Waivers. GENUITY and GTE waive all rights to recover against each
          -------
          other for any Loss to their respective tangible personal property
          (whether owned or leased) from any cause covered by insurance
          maintained by each of them, including their respective deductibles or
          self-insured retentions. GENUITY and GTE shall cause their respective
          insurers to issue appropriate waivers of subrogation rights
          endorsements to all property insurance policies maintained by each
          party. Each party shall give the other written notice if a waiver of
          subrogation is unobtainable or obtainable only at additional expense.
          If the party receiving such notice agrees to reimburse the other party
          for such additional expense, the other party shall obtain such waiver
          of subrogation. If a waiver is unobtainable or if a party elects not
          to pay the additional expense of a waiver, then neither party nor
          their insurers shall waive such subrogation rights.

                                       13
<PAGE>

     (d)  Conditions. The indemnification obligations set forth in this
          ----------
          Section 11 shall not apply unless the party claiming indemnification:
          (i) notifies the other promptly in writing of any matters in respect
          of which the indemnity may apply and of which the notifying party has
          knowledge, in order to allow the indemnitor the opportunity to
          investigate and defend the matter; provided, however, that the failure
          to so notify shall only relieve the indemnitor of its obligations
          under this Section 11 if and to the extent that the indemnitor is
          prejudiced thereby; and (ii) gives the other party full control of the
          response thereto and the defense thereof, including any agreement
          relating to the settlement thereof. However, if the indemnitor fails
          to promptly assume the defense of the claim, the party entitled to
          indemnification may assume the defense at the indemnitor's cost and
          expense. The indemnitor shall not be responsible for any settlement or
          compromise made without its prior written consent, unless the
          indemnitee has tendered notice and the indemnitor has then refused to
          assume and defend the claim and it is later determined that the
          indemnitor was obligated to assume and defend the claim. The
          indemnitee agrees to cooperate in good faith with the indemnitor at
          the request and expense of the indemnitor.

12.  LIMITATION OF LIABILITY.

     (a)  General.  A party's and its affiliates' liability arising out of or
          -------
          relating to a Statement or Statements of Work and this Agreement,
          including without limitation on account of performance or
          nonperformance of obligations hereunder, regardless of the form of the
          cause of action, whether in contract, tort (including without
          limitation negligence), statute or otherwise, shall in no event exceed
          the lesser of (i) the price to be paid to Service Provider for the
          completed Statement of Work (whether set out as a fixed price,
          estimated price, not-to-exceed amount, or other similar expression of
          the total price for the work to be performed under the Statement of
          Work); (ii) the amount actually paid by Service Recipient to Service
          Provider for the particular Statement of Work from which the claim
          arises; or (iii) if the price to be paid to Service Provider for the
          Statement of Work is expressed as a recurring periodic charge, the
          liability shall be limited to the average of three (3) months charges
          for technical services based on the average previous twelve (12)
          month's (or such lesser number of months that the Statement of Work
          has been in effect) of the invoices actually paid by Service Recipient
          under the Statement of Work. The limitation in the immediately
          preceding sentence does not apply to a party's obligations under the
          Sections entitled Indemnification and Confidential Information, nor
          does it apply to willful misconduct or gross negligence on the part of
          a party.

                                       14
<PAGE>

     (b)  Limitation. EXCEPT FOR BREACHES RELATED TO CONFIDENTIAL
          ----------
          INFORMATION, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY
          INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR CONSEQUENTIAL
          DAMAGE OR LOST PROFITS OF ANY KIND WHATSOEVER EVEN IF A PARTY OR ITS
          AFFILIATES HAVE BEEN APPRISED OF THE LIKELIHOOD OF SUCH DAMAGES
          OCCURRING.

     (c)  Benefits Under Licenses.  Anything contained herein to the contrary
          -----------------------
          notwithstanding, this Agreement shall not constitute an agreement to
          start work, to provide Services or Work Product or to make available
          to Service Recipient the benefits under any agreement, license or
          arrangement if doing so without the consent of and/or payment to
          another party thereto would constitute a breach thereof or in any
          material way affect the rights of Service Provider thereunder, unless
          and until such consent is obtained and payment, if any, made to such
          party by Service Provider. Service Provider shall use commercially
          reasonable efforts to secure such consents and benefits under any such
          agreement or arrangement. If Service Provider cannot: (i) obtain such
          consent; or (ii) Service Provider and the third party vendor cannot
          agree on a commercially reasonable payment, if such is required, or
          (iii) if providing the Services or Work Products or making the
          benefits under any such agreement, license or arrangement available
          would materially affect Service Provider's right thereunder, Service
          Provider shall not be required to provide any Services or Work
          Products which are dependent upon any agreement, license or
          arrangement as to which the third party provider has objected in
          writing to making the benefits of such agreement, license or
          arrangement available to Service Recipient. Service Recipient may,
          however, obtain the requisite license or pay such fees that it deems
          appropriate in order for Service Provider to provide the Services, if
          Service Provider's provision of Services pursuant to such Service
          Recipient License or payment is without any adverse material affect to
          Service Provider.

13.  CHANGES IN MANNER OF PROVIDING SERVICES.

     Service Recipient acknowledges that Service Provider and its affiliates may
     in the future determine to outsource certain information technology
     functions or perform such functions using different computer software
     operating systems or applications. These changes may prevent Service
     Provider from providing certain Services or Work Products to Service
     Recipient pursuant to this Agreement in the manner in which they have been
     provided prior to such change. In the event Service Provider determines to
     take any such action, it will provide Service Recipient with one hundred
     twenty (120) days prior written notice and will cooperate with Service
     Recipient to enable Service Recipient to continue to receive any affected
     Services and Work Products through arrangements with

                                       15
<PAGE>

     Service Provider's outsource providers or through conversion of Service
     Recipient data for use on such operating systems or applications. In the
     event Service Provider determines to make such changes, Service Recipient
     shall have the right to terminate this Agreement or any affected Statement
     of Work without any liability or penalty. Any customizations requested by
     Service Recipient within or to the systems utilized by Service Provider to
     provide the Services shall be at Service Provider's discretion. Service
     Recipient shall be required to pay the mutually agreed upon cost of such
     customizations.

                            To Provide Support For:
                       Computing Infrastructure Services

1.0  Management Summary

1.1  Introduction

     This Statement of Work is appended to the Agreement for IT Transition
     Services dated ________________________, 2000 by and between Genuity
     Solutions Inc. ("Genuity") and GTE Service Corporation and its affiliates
     and shall be governed by the terms and conditions thereof. The services
     described herein shall be provided by GTE Data Services Incorporated
     ("GTEDS") for a period of up to 12 months effective upon the Effective Date
     of the Agreement for IT Transition Services. This Statement of Work may not
     be renewed.

1.2  Executive Summary

     GTEDS is currently providing computing infrastructure information
     technology services to Genuity.  These computing infrastructure services
     include providing phone and desk-side support to Genuity personnel and
     their desktop computing equipment ("End User Support");  providing network
     connections and transmission for Genuity personnel and equipment ("Network
     Support");  supporting shared computer hardware and software utilized by
     Genuity personnel to accomplish business functions ("Server Operations and
     Support");  and supporting telephonic services (voice and FAX) for Genuity
     personnel ("Voice Services and Support").  All interLATA telecommunications
     services provided are in compliance with Section 271.

     These services are required during the separation and transition of Genuity
     due to Genuity's short-term inability to provide these services due to the
     particular locations of the Genuity personnel or equipment, the skills
     required to provide these services at the sites, or the lack of Genuity
     labor at these locations to apply to these services.

     Genuity will receive these services for up to 12 months effective upon the
     date of execution of the Agreement.

                               Statement of Work
                                    Between
                            GTE Service Corporation
                                      and
                            Genuity Solutions Inc.
                                  To Provide
                         Continuing Operations Support
                               For Applications

1.   Management Summary

     1.1.  Introduction

           This Statement of Work is appended to the Agreement for Information
           Technology Transition Services ("Agreement") dated
           ________________________, 2000 by and between Genuity Solutions Inc.
           ("Genuity") and GTE Service Corporation and its affiliates and shall
           be governed by the terms and conditions thereof. The services
           described herein shall be provided by GTE Data Services Incorporated
           ("GTEDS") for a period of up to 12 months effective upon the
           Effective Date of the Agreement for IT Transition Services. This
           Statement of Work may not be renewed.

     1.2.  Executive Summary

           GTEDS is providing currently computing continuing operations support
           for some Genuity applications. Computer applications are computer
           programs that perform or support Genuity business functions.
           Continuing operations support comprises those activities that keep
           these applications performing correctly and efficiently, including
           remedial action in the event of errors or failures.

           These services are required during the separation and transition of
           Genuity due to Genuity's short-term inability to provide these
           services due to the particular skill sets involved in continuing
           operations, the experience levels of current GTEDS continuing
           operations personnel, and the knowledge inherent in these personnel.

           Genuity will receive these services for a maximum period of 12 months
           effective upon the date of execution of the Agreement.

2.   Scope Of SOW

           following tasks:

                    statements
               .    Providing requested periodic reporting of effort and/or
                    performance
               .    Perform daily operational activities to ensure that
                    production activities are performed and controlled as

               .    Attend monthly performance review meetings to present
                    performance and review status

     1.8  Proposed Solution

          This project is for implementing future releases of TBS so that
          Genuity can take advantage of the technology improvements.

          The TBS (Telecom Business Solution) went into production in Ft. Wayne
          and is used by GTE Telecom and Global Network Infrastructure (GNI) in
          December 1998. GTEDS currently has the Contract with MetaSolv for all
          aspects of the TBS System.

          The TBS (Telecom Business Solution) System is a stand-alone system
          that provides order management, workflow management, inventory
          management and network design capabilities. TBS software system sends
          and receives ASR, LSR, PSR and ISR forms.

          PSR Module (Product Service Request) is an ordering engine that allows

                                                                   Page 3 of 8
<PAGE>

          users to order and provision products which allow customers to create
          customer accounts, set up product catalog for line, circuit, and non-
          premise products as well as order and provision products from the
          catalog for customers.

----------------------------------------------------------------------------------------------------------
</TABLE>

          After Genuity approves the SOW and provides the authorization to
          proceed, GTEDS will schedule all final due dates and provide an
          implementation plan, in addition to this matrix, that shows the
          logical sequences of events and key milestones. Key milestones on the
          critical path shall be closely monitored by GTEDS to ensure that
          schedule risk is minimized and alternate paths and/or solutions are
          available if needed.

          If this SOW is to be part of a release package, GTEDS will provide a
          complete schedule after Genuity identifies all work to be contained in
          the release. Additional charges for infrastructure or other release
          packaging charges will be identified and presented at the time of
          final packaging.

           Statement of Work for GTEDS providing service to Genuity:
                         TBS Performance Improvements

1.0   Management Summary

    1.1  Introduction

         This Statement of Work is appended to the Agreement For IT Transition
         Services ("Agreement") dated _________ by and between Genuity Solutions
         Inc. ("Genuity") and GTE Service Corporation and its affiliates and
         shall be governed by the terms and conditions thereof. The services
         described herein shall be provided by GTE Data Services Incorporated
         (GTEDS) for a period of the earlier of one year from the Effective Date
         of the IT Transition Services Agreement or the date of completion of
         the work. This Statement of Work may not be renewed.

    1.2  Executive Summary

         Genuity uses an operational support system called Telecom Business
         Solutions(C) (TBS) to accept new service orders and to design circuits
         for its customers. The performance of this system is decreasing due to
         rapid customer growth. This system currently runs on GTEDS computers in
         a GTEDS data service center. This project addresses the performance
         problem by having GTEDS install additional server hardware capacity to
         improve system performance. This will allow time for GTEI to train its
         staff and make provisions for moving this system to Genuity's data
         center. This transition will be complete within one year from execution
         of this statement of work.

    1.3  Scope/Objective

         This scope of work encompasses the delivery of a cost estimate and a
         time estimate to provide a systems solution for TBS Performance
         Improvements per the Genuity Business Case which states:

         Two NT servers will be added between the E10K servers in the Fort Wayne
         Data Center and the clients. The additional servers will de-load the
         clients to increase performance. An additional benefit is that only the
         NT boxes will have to be upgraded with new versions of TBS and not all
         the clients.

    1.4  Scope Requirements

         .   Provide a cost estimate to provide the systems solution to the
             requirements provided by Genuity.

         .   Provide a time period estimate to provide the systems solution to
             the requirements provided by Genuity.

                                                                     Page 1 of 7
<PAGE>

    1.5  Assumptions

         .   Genuity will provide the business functional requirements, targeted
             user environment description, and performance requirements that
             must be delivered by a systems solution.

         .   Genuity will provide a target date by which a systems solution is
             to be available for Genuity user operations.

         .   Genuity will respond within 5 business days to a request for
             clarification of requirement(s).

         .   Genuity will provide a description of any preferred
             hardware/software/network environment to which a systems solution
             should conform.

         .   All of the work performed hereunder shall be in accordance with the
             Service Level Agreement for the Application Enhancement and
             Development of even date herewith.

                                                                     Page 2 of 7

           Statement of Work for GTEDS providing service to Genuity:
                         Automated TBS ASR Processing

Management Summary

   Introduction

        This Statement of Work is appended to the Agreement For IT Transition
        Services ("Agreement") dated _________by and between Genuity Solutions
        Inc. ("Genuity") and GTE Service Corporation and its affiliates and
        shall be governed by the terms and conditions thereof. The services
        described herein shall be provided by GTE Data Services Incorporated
        (GTEDS) for a period of the earlier of one year from the Effective Date
        of the IT Transition Services Agreement or the date of completion of the
        work. This Statement of Work may not be renewed.

   Executive Summary

        In order to provide a cross-country circuit for a customer, Genuity must
        often lease a short "tail circuit" from the customer's location to the
        nearest Genuity network access location.  Today, Genuity requests tail
        circuits from other telephone companies manually (e.g. by faxing an
        order form to them).  This project automates that process by enabling
        Genuity to electronically send tail circuit orders to telephone
        companies.

        This project work is already in-progress and entails specialized skills
        in GTEDS.  This capability is needed by October 2000 and Genuity does
        not have the staff to complete the project by that date. Transfer of the
        project to another vendor could delay the availability of the
        functionality.

   Scope/Objective

        This scope of work encompasses the delivery of a cost estimate and a
        time estimate to provide a systems solution for Automated TBS ASR
        Processing per the Genuity business case which states:

        This project would eliminate the duplicate manual entry thereby
        improving the efficiency of the business process and improving the
        accuracy of the data.

   Scope Requirements

        .    Provide a cost estimate to provide the systems solution to the
           requirements provided by Genuity.

        .    Provide a time period estimate to provide the systems solution to
           the requirements provided by Genuity.

                                                                     Page 1 of 7

     Assumptions

          .      Genuity will provide the business functional requirements,
              targeted user environment description, and performance
              requirements that must be delivered by a systems solution.

          .      Genuity will provide a target date by which a systems solution
              is to be available for Genuity user operations.

          .      Genuity will respond within 5 business days to a request for
              clarification of requirement(s).

          .      Genuity will provide a description of any preferred
              hardware/software/network environment to which a systems solution
              should conform.

          .      All of the work performed hereunder shall be in accordance with
              the Service Level Agreement for the Application Enhancement and
              Development of even date herewith.

                                                                     Page 2 of 7

1.0       Management Summary

     Introduction

               This Statement Of Work is appended to the Agreement for IT
               Transition Services ("Agreement") dated _________by and between
               Genuity Solutions Inc. ("Genuity") and GTE Service Corporation
               and its affiliates and shall be governed by the terms and
               conditions thereof. The services described herein shall be
               provided by GTE Data Services Incorporated (GTEDS) for a period
               of the earlier of one year from the Effective Date of the IT
               Transition Services Agreement or the date of completion of the
               work. This Statement of Work may not be renewed.

               This SOW outlines the tasks required by GTEDS for support of
               "Smallworld- Release 5".

     Executive Summary

               Genuity uses a network and facility engineering design package
               called "Smallworld". GTEDS currently supports Smallworld and has
               been previously engaged to do several projects to improve the
               accuracy of Smallworld data and enhance the usability of the
               package.

               This work is already well underway and entails specialized skills
               in GTEDS. It is expected to complete in September 2000 and
               Genuity does not have the staff to complete the project by that
               date.

2.0       Scope of Work

     2.1       Scope/Objective

               The scope of work for this Statement of Work includes all
               remaining system requirement tasks, high level system designs,
               detail designs, program management tasks including development
               workplans, and estimates for delivery of all Smallworld Release 5
               components.

               A change request to this SOW will be issued for the remaining
               development, testing, implementation and training activities
               occurring after 04/28/00.

     2.2       Scope Requirements

               Based on the information provided by "Genuity" regarding Release
               5, the scope of each specific component is as follows:

                    [_]  SMW/GRS Reconciliation
                         Development of workplans, estimates, detail designs and
                         some coding efforts

                                                                     Page 1 of 7
<PAGE>

                    [_]  Remote Access (Phase 1)
                         Development of workplans, estimates, demo, detail
                         designs, and selection and configuration of COTS
                         products

                    [_]  SMW Engineering Enhancements - Release 5
                         Definition of scope, development of workplans and
                         estimates, high level designs

                    [_]  Automated Engineering Packages - Revised Solution
                         Development of workplans, estimates, detail design
                         tasks and some coding efforts

     2.3       Work Package Description Summary

               See Attachment A, the Requirement and Conceptual Solution
               Document, for a summary of GTEDS understanding of the requested
               functionality. This Attachment references the Software
               Requirements Specification documents for targeted Release 5
               components.

     2.4       Assumptions

               It is assumed that this work effort is for the time period from
               04/01/00 through 04/28/00. Code Drop for these SMW Release 5
               efforts will be identified and confirmed in a subsequent SOW
               change request.

               A change request to this SOW, incorporating all Smallworld
               Release-type activities, will be submitted to address the normal
               systems testing, UAT, and implementation activities performed in
               support of the verification of all Smallworld application release
               enhancements.

               "Genuity" resources are available and will support the planned
               efforts targeted prior to the effective date of this SOW.
               Included are:

               .  the pre-planning and "As Is" business process definition
                  session scheduled for February 23 and February 24, 2000 in
                  support of the Automated Engineering Packages - Revised
                  Solution
               .  The follow-up session to map the "As Is" business processes of
                  the proposed "To Be" business processes scheduled for February
                  28 through March 3, 2000.
               .  the requirements clarification or "white-board" sessions in
                  support of the ISP/Smart Power/HVAC enhancements to enable
                  delivery of cost estimates and functionality within
                  development windows for Release 5
               .  timely decisions on the SMW/GRS Reconciliation direction to
                  enable functionality to be delivered within the Release 5
                  development window
               .  the Step 2 demonstration of the Remote Access solution set as
                  requested by "Genuity" for presentation in March

               This SOW does not include work effort or costs for the SALAD
               group to perform any required interoperability testing in support
               of Smallworld Release 5. SALAD has identified themselves as a GNI
               organization and therefore should secure funding independent of
               this GTEDS SOW.

     2.5       Roles and Responsibilities

               GTEDS and "Genuity" team will have the following roles and
               responsibilities during the activities:

                                                                     Page 2 of 7

                     timeframes identified within this SOW. However, if travel
                     needs do arise, GTEDS will identify and may request
                     authorization and approval from "Genuity" prior to travel.

             2.6.b   If approved, GTEDS may invoice "Genuity" for approved
                     reimbursable travel expenses at actual costs incurred as a
                     result of performance under a Statement of Work
                     ("Reimbursable Travel Expenses") in accordance with the
                     Master Contract.

          Acceptance Criteria

             GTE Data Services will ensure that the following criteria are met
             in the delivered product:

              .       GTEDS will provide a complete and integrated design that
                      will provide functionality as specified in the Requirement
                      and Conceptual Solution Document, as of the date of the
                      approved SOW.
              .       GTEDS will retain documented functionality of previous
                      Releases and SOWs where the functionality is unchanged.

          Reporting Requirements

             None

3.0        Special Considerations

                                    Between
                            GTE Service Corporation
                                      And
                             Genuity Solutions Inc.
                                   To Provide
                           Web Based Interface to PSR
1.0  Management Summary

     1.1  Introduction

        This Statement Of Work is appended to the Agreement for IT Transition
        Services ("Agreement") dated _________ by and between Genuity Solutions
        Inc. ("Genuity") and GTE Service Corporation and its affiliates and
        shall be governed by the terms and conditions thereof. The services
        described herein shall be provided by GTE Data Services Incorporated
        (GTEDS) for a period of the earlier of one year from the Effective Date
        of the IT Transition Services Agreement or the date of completion of the
        work. This Statement of Work may not be renewed.

        This SOW outlines the tasks required by GTEDS for support of "Web Based
        Interface to PSR".

     1.2  Executive Summary

        Genuity uses an operational support system called Telecom Business
        Solutions(C) (TBS) to accept new service orders and to design circuits
        for customers. Each user of this system is required to install a large,
        complicated, expensive program on his PC. Only a small number of users
        need the full capabilities of this large program. Most users only need
        the ability to enter and check the status of orders. This project makes
        those order management capabilities available via a standard Web Browser
        which already exists on everyone's PC.

        This work is already well underway and entails specialized skills in
        GTEDS.  It is expected to complete in August 2000 and Genuity does not
        have the staff to complete the project by that date.

     1.3  Scope/Objective

          This scope of work included the following deliverables:

               .  Updated Project Plan
               .  Updated Software Requirements Specification
               .  Monthly Status Reports
               .  Updated Training Requirements Documentation
               .  User Acceptance Test Plan and Test Scripts

          Creation of a web based interface to existing TBS PSR module for order
          entry. Future phases will include capability to export status and
          tracking information from the PSR.

       Genuity acknowledges that the Web Based Interface, and all designs and
       code, Web pages created herein, for this Statement Of Work, are developed
       for use by multiple entities, including Genuity.

                                                                    Page 1 of 10
<PAGE>

     1.4  Scope Requirements

           Based on the information provided by Genuity regarding the web-based
           interface to PSR, the scope of the project is as follows:

            .   This will provide a web-based interface into TBS/PSR for order
              entry, tracking and status update. PSR is the order entry module
              of TBS, which is developed by the vendor Metasolv. This will
              enable field and remote personnel to access limited TBS/PSR
              functionality remotely. Project will leverage the Genuity effort
              currently underway to provide web access to the CODA system. A
              conceptual diagram of the interface is shown in Appendix A.
              Detailed order status and tracking will not be available until
              Metasolv can deliver the work management API (currently scheduled
              for April 2000).

     1.5   Work Package Description Summary

           See Attachment A, the Requirement and Conceptual Solution Document,
           for a summary of GTEDS understanding of the requested functionality,
           and our conceptual solution for the request.

     1.6   Assumptions

            .    Several stages of the project will be performed in parallel
               rather than sequentially.
            .    Project team will be able to leverage the design and building
               efforts that went into the GNI internally developed CODA (Circuit
               Order Data Analysis) data base, especially during requirements
               sessions.
            .    There will be no requirement to provide ad hoc reports to end-
               users.
            .    Products not in PSR as of a to be determined freeze date will
               be provided as future release/upgrade.
            .    Project will not result in loss of current CODA reporting
               functions.
            .    Telecom sales end users will access detailed service/circuit
               information (beyond what is available through standard reports)
               by direct contact with the Telecom CSC

                                                                    Page 2 of 10

     1.8 Proposed Solution

         The web-based interface to TBS-PSR will be provided by using the TBS-
         PSR API from Metasolv.  This will provide a 2-way interface into TBS
         for entering orders into the PSR and retrieving high level tracking and
         status information from the TBS database. This is dependent upon the
         installation of TBS V4.2.  Web pages, server, and required databases
         will be delivered by GTE-IT.  Detailed functionality requirements and
         design will be defined during a 2 phase requirements gathering session.
         Expected hardware and network requirements include connectivity via the
         GTE inter-WAN for the API server and web server, external connectivity
         for remote and field personnel using the web.  Details of network and
         hardware requirements will be defined during the network and technical
         architecture review stages.

                                                                    Page 3 of 10

            After Genuity approves the SOW and provides the authorization to
            proceed, GTEDS will schedule all final due dates and provide an
            implementation plan, in addition to this matrix, that shows the
            logical sequences of events and key milestones. Key milestones on
            the critical path shall be closely monitored by GTEDS to ensure that
            schedule risk is minimized, and alternate paths and/or solutions are
            available if needed.

4.2  GTE Data Services' Deliverables

     GTE shall prepare and deliver the following to Genuity in accordance with
     the requirements of the Statement Of Work recognizing that time is of the
     essence with respect to the Deliverables. Genuity shall review and accept
     or reject the Deliverables in accordance with documented acceptance
     criteria.

     Deliverable #1 - Statement Of Work

          Based on a the receipt of a Work Request, GTE will analyze the request
          and prepare a Statement Of Work which documents the solution overview,
          implementation time, implementation price and assumptions. Genuity
          will review the Statement Of Work. If Genuity accepts the Statement Of
          Work, a signed copy will be returned to GTEDS.

     Deliverable #2 - Development Plan and Schedule

          GTE shall provide an initial written Project Plan by the date
          documented in the Statement of Work. The written Project Plan shall be
          developed using a standard project management software package.  The
          plan shall identify each phase of the development process with the
          corresponding start and end dates, and effort required for each phase.
          Within each phase, the plan shall identify each deliverable, or work
          package created out of the process with their corresponding start and
          end date and effort. It shall also include milestones, inspections,
          dependencies and critical path of the deliverables. The plan shall be
          monitored by both GTE and Genuity to ensure that no project jeopardy
          conditions arise.

                                                                    Page 6 of 20
<PAGE>

          The Project Plan will be submitted for approval to Genuity according
          to the agreed upon Statement of Work. Genuity shall approve or
          disapprove the plan within five (5) working days. If the plan is not
          approved, Genuity will clearly communicate in writing the corrections
          that need to be made to the plan. GTE will revise the plan within five
          (5) working days and resubmit it to Genuity. Work may be delayed if
          the plan is not approved within the specified time frame.

          It is expected that GTE will have a more detailed work plan and
          schedule that is used to manage their own detail steps, processes and
          staff. This plan may change repeatedly as necessary. The Project Plan
          submitted to Genuity may only change as a result of formal Change
          Control. The Change Control process is specified in the Statement Of
          Work.  If GTEDS requires a change to the Project Plan, they must
          submit a Change Request to Genuity as defined in the Statement Of
          Work.

     3. Next level is GTE Section Manager
     4. Next level is GTE Manager
     5. Next level is the GTE Director
     6. Next level is GTE Vice President
     7. Final level is the GTE Vice President

     Current escalation flow from GTE to Genuity:

     1. GTE beeps twice.  If no answer...
     2. Next level is Genuity Section Manager
     4. Next level is Genuity Manager
     5. Final level is Genuity Director

     GTE and Genuity will each ensure that the other has been provided  an
     escalation list that includes home, work and beeper numbers for pertinent
     personnel.

6.0  Performance Measures and Acceptance Expectations

6.1  Timeliness of Deliverables

     Deliverables are defined as those items created in the development process
     that are listed in Section 4.2 and those delivered to Genuity. Examples
     include but are not limited to completion of documentation and delivery of
     code.

     All Deliverables will be delivered on the due date documented on the
     Statement of Work or approved Project Plan. If a deliverable is not
     complete on the due date, GTE will use commercially reasonable efforts
     necessary to expeditiously complete the Deliverable as soon as possible. If
     either party requires a change to the due date of a deliverable, then they
     must submit a Change Control Request to the other party as defined in the
     Statement Of Work.

6.2  Acceptance Criteria of Deliverables

     GTE will develop each Deliverable to meet the documented Acceptance
     Criteria in the Statement Of Work. If additional Acceptance Criteria is
     needed then the corresponding Acceptance Criteria will be defined as
     documented in the Project Plan.

     Genuity shall accept or reject each Deliverable, in writing, in the agreed
     to time period documented in the Project Plan.  If rejected, Genuity shall
     clearly state the reason(s) for rejection.  GTE shall present a suitable
     correction and completion date to Genuity.  GTE shall then make the
     corrections and resubmit the Deliverable.

                                                                   Page 10 of 20
<PAGE>

6.3  User Acceptance Test and Warranty Support

   The purpose of the Pre-production testing is to ensure that the enhancements
   made to the system function in accordance with the Customer Requirements and
   the High Level Design. It is also to ensure that the unmodified code and
   continuing functions, logically process per the current documented
   specifications.

   During User Acceptance Testing, the role of GTE is to provide technical
   support by executing the physical programs and technical procedures and
   correcting any errors found in the coding logic. During User Acceptance Test
   and Warranty, the role of GTE is to provide technical support, correct any
   errors found in the coding logic, and ship the code to Genuity.

   The types of Incident Requests (IRs) that can arise during the test and the
   expected response time to address those IRs are documented in Attachment B.

   The IR goals/targets/baselines for performance reporting have been set as
   indicated below. A low number of incoming IR quantities will have a tendency
   to skew the results either higher or lower on a month to month basis.

  .  Goal      90-100% on time resolution
  .  Target    85-89% on time resolution
  .  Baseline  80-84% on time resolution

  These terms are defined as follows:

  Goal     -  Grade of service that GTE will be striving for
  Target   -  Grade of service that should initially be expected
  Baseline -  This should be the minimum quality of service provided by GTE for
              resolution of IRs. When the on-time resolution percentage is in
              this range, appropriate action should be taken to improve results.

6.4  Returned IR Parameters

Returned IRs are considered problem fixes that have been implemented in the
customer's environment, either in User Acceptance Test or Warranty, and Genuity
and GTE have determined that the fix did not resolve the problem described in
the IR.  For returned IRs, the original IR number is used.  If the returned IR
has been closed a new one is opened. Returned IR goals have been set as
indicated below. Low number of incoming IR quantities will have a tendency to
skew the results either higher of lower on a month to month basis.

  .  Goal     0 - 5% returned
  .  Target   6 - 10% returned
  .  Baseline  11 - 15% returned

                                                                   Page 11 of 20
<PAGE>

  These terms are defined as follows:

  Goal     -  Grade of service that GTEDS will be striving for
  Target   -  Grade of service that should initially be expected based
  Baseline -  This should be the minimum quality of service provided by GTE
              for resolution of IRs. When the on-time resolution percentage
              is in this range, appropriate action should be taken to improve
              results.

7.0  Time Reporting

GTE will provide timely and accurate time reporting of the hours expended to
complete the effort defined in the Statement Of Work. Time reported to complete
a Statement Of Work will only be shared with Genuity if the Statement Of Work
payment terms are based on time and materials.

For IRs, Time will be reported at the IR number level. Time reporting will be
created by IR containing hours by defect and non-defect IRs.

For enhancements, hours will be separated and reported by

  .  Requirements Support

  .  High Level Design and/or Support

  .  Detail Design

  .  Code / Unit Test

  .  System Test Support

  .  User Acceptance Test Support

GTE will be using existing practices developed by GTE Information Technology as
the basis for detailed instruction/direction for IR service delivery as well as
development and enhancements.  In the Information Technology Practices, standard
Quality Assurance processes for reviews, inspections, testing, etc. are defined.
As the business demands, these practices will be updated to ensure GTE is
positioned to best serve the customer.

                                                                   Page 12 of 20
<PAGE>

8.2  Quality Procedures

GTE shall adhere to rigorous Quality Control and Quality Assurance procedures to
ensure Deliverables are satisfactorily completed.  GTE's Quality Control and
Quality Assurance procedures shall ensure that:

 .  Deliverables meet the requirements

 .  Deliverables are executed within the agreed time frame

 .  Project Deliverables have minimal defects, as defined in the acceptance
   criteria, when delivered to Genuity or delivered to the next stage/activity
   within the project

 .  Product deliverables are maintainable and can be enhanced to Genuity's
   requirements

 .  Project statistics are collected for improvement in processes and also for
   use as the historical basis for enhancing the accuracy of future estimates

9.0  Continuous Process Improvement

 If a process needs to be developed or refined as a result of implementing a
Statement of Work, reporting the hours expended, or negative performance against
service levels, then a process development plan will be developed, agreed to and
executed jointly by GTE and Genuity. Upon implementation of the plan, both
parties will monitor for improvements. Either party will report at the Project
Review Meeting as soon as it is determined that these actions have corrected the
deficiencies. Either party will also report if processes are not working,
thereby causing them not to meet the terms and conditions outlined in this
agreement.

                                                                   Page 13 of 20

1.  Management Summary
    1.1.  Introduction

    This Statement of Work is appended to the Agreement for Transition Services
    dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
    Service Corporation and its affiliates and shall be governed by the terms
    and conditions thereof. The services described herein shall be provided by
    GTE Data Services Incorporated ("GTEDS") for a period of the earlier of the
    date of completion of the work or December 31, 2000.

    1.2.  Executive Summary

    Genuity desires to continue the ongoing development of a Global Network
    Infrastructure Performance Management ("GNI PM") solution with GTEDS. The
    GNI PM solution, as referenced herein in more detail, enables Genuity's
    customers to access appropriate performance data. Genuity has determined
    development of such a solution involves skill sets and core competencies
    currently not internally available. Using another provider for the
    development of the GNI PM solution could delay Genuity's current business
    plans. Accordingly, Genuity desires to complete the work as contained herein
    within the stated time frame, and GTEDS desires to continue this work during
    this transition period.

2.  Scope of SOW

    2.1.  Scope/Objective
    This document describes the proposed work for the Phase III development of
    new features and enhancements to TIPS, the Performance Management and SLA
    validation solution deployed at GNI to measure and report on the SONET, ATM
    and Frame Relay services of GNI, within the framework of Customer Service
    Assurance.

    Background: GTE's Global Network Infrastructure (GNI) is a state-of-the-art
    network based on a nationwide SONET-192 backbone, which supplies both
    switched and routed broadband data transport. It is a complex network whose
    management responsibilities are shared between GNI and its customers. Figure
    1 below outlines the architecture of GNI and demarcates the areas of network
    management responsibility for SONET, ATM and FR segments deployed in the
    Network.

                                                                    Page 1 of 15

                             [GRAPH APPEARS HERE]
                 Fig. 1 Demarcation of Responsibilities in GNI

     For network management purposes, Customer Premises Equipment lies wholly
     within the customer's control and responsibility. The performance of the
     core SONET-and-ATM network is wholly the responsibility of GNI; at Edge
     Switches and at ATM and Frame Relay User-Network interfaces, there is an
     overlap of responsibility between GNI and the customer (compare Figure 2,
     below). That is, GNI is responsible for monitoring customer traffic at the
     User-Network Interface, while the customer is responsible for incoming
     traffic's satisfying the terms of the traffic contract.

              Fig. 2 Overlap of GNI and Customer Responsibilities

                                                                    Page 2 of 15

                                   SOW - GNI Performance Management Phase III/IV
--------------------------------------------------------------------------------

     Most explicitly, GNI will be entirely responsible for the network from the
     point of UNI attachment at an Optical Point of Presence (OPOP) to the point
     of exit from GNI at an OPOP, not simply from switch port to switch port.
     GNI also has partial responsibility beyond the OPOP toward customer
     equipment: in the case of customers whose traffic reaches the GNI network
     via a LEC link, GNI will assume responsibility to monitor the intermediate
     link as well.
     When symptoms of performance problems surface in the network, it is
     extremely difficult to determine their focus. ATM is a highly complex
     technology with sophisticated traffic management schemes designed to
     guarantee Quality of Service, which make troubleshooting any problem a
     matter of considerable difficulty.

     2.2. The Overall Problem Statement
     There is for GNI, therefore, an authentic need for an effective tool or
     solution capable of gathering, processing and analyzing the vast amount of
     performance data that ATM, Frame Relay and SONET traffic generates, both
     for its own sake and in support of Fault Management and Customer Care.
     There is also a need to use this data to manage the Customer SLAs on the
     various services being offered by GNI. GNI will gain market edge by not
     only tracking and validating SLAs on its end-to-end ATM, Frame Relay
     services, but making the Performance and SLA-Exception reports directly
     available to its customers.

     2.3. The Proposed Solution and Previous TIPS Deliveries
     TIPS, a system built by Operations Systems Laboratory of GTE Laboratories,
     has been deployed at GNI as a solution to the above posed problem of SLA
     validation and Customer Services Performance Management for ATM and SONET
     networks. TIPS collects performance and fault data from network management
     systems (NMSs, Ascend BulkStats) and network topology information from data
     warehouses (eg. Remedy, TBS) and NMSs (NavisCore, INM TM) and estimates and
     reports on the customer service performance levels. Using these estimates,
     TIPS is able to validate the SLAs and identify services for which customer
     SLAs may not have been met.
     In its current state, TIPS is in production for ATM customer services and
     produces Throughput and Availability reports for circuits, PVCs, SVCs,
     Trunks and Ports. It also produces delay reports for the test circuits set
     up by the INQIRE system NIL. Due to unavailability of valid and clean data
     from the Remedy interface, the SONET reports have not been put into
     production yet.

     2.4. Proposed Work for Phase III and Phase IV
     The basic areas in which work will be done in Phase III and IV can be
     categorized as follows:

          . Interfacing with TBS, a central data repository for customer
            services related information.
          . Secure user/customer access to TIPS reports via a new authentication
            and authorization procedure.
          . Upgrade to Naviscore Jade M2.1.
          . Enhancement of report presentations (more graphical, variety of
            formats).
          . Enhancements, including adding more statistics, configuration
            information to existing reports, oversubscribed port exclusions.
          . Deriving latency measurements between all pairs of ports.

                                                                    Page 3 of 15

                                   SOW - GNI Performance Management Phase III/IV
--------------------------------------------------------------------------------

          . New Customer Billing Summary report, trunk and port utilization
            reports and backhaul report
          . New web-based TIPS administration tools.

The goal of the Phase III/IV solution is to support and further enhance GTE
GNI's capabilities of monitoring customer network services using TIPS. The
overview of the work to be done in these phases is outlined in section 1.5. The
detailed matrix and a schedule is in the following table. It should be noted
that here Phase III means a delivery date at the end of 2Q, and Phase IV means a
delivery date at the end of 4Q.

     2.5. Risks
     There will be some risk of the final system not fully delivering all the
     features specified in this document. This is due to the uncertainty of
     certain aspects to the development, which cannot be fully assessed before
     the project has started. The project will make a best effort to deliver
     based on available interfaces and data, but the issues listed below may
     prevent some functionality in the phase I software deliverable.

     TBS Interface
     In order to automatically load the customer contact information and billing
     ids, the solution will need to interface with TBS in order to gather
     appropriate data. This interface has not yet been fully deployed or fully
     tested and may be insufficient to provide all the data required, or may
     contain software bugs that otherwise cause limitations on data gathering
     capabilities.

                                                                    Page 6 of 15

                                     SOW-GNI Performance Management Phase III/IV
--------------------------------------------------------------------------------

     SONET Reporting
     Data for SONET needs to come from TBS and may also need to come from INM
     Trail Management BB. It is unclear if this data is sufficient to allow
     accurate estimates of SONET circuit performance. Another risk associated
     with SONET PM is that the amount of performance data collected may impose
     bandwidth requirements that exceed the bandwidth availability of the OAM&P
     network. This requires further evaluation.

     2.6.Roles and Responsibilities:
     GTEDS and Genuity team will have the following roles and responsibilities
     during the activities:

BIP-8              SONET      BIP-8 is a single interleaved parity byte (B1) used to
                              provide STS-n error monitoring. BIP performs a
                              routine even parity check on the previous STS-1
                              frame. The parity is then inserted in the BIP-8 field
                              of the current frame. SONET relies on even parity
                              for its error checking calculations. During parity
                              checking, the first bit of the BIP-8 field is set so that
                              the total number of ones in the first positions of all
                              bytes in the previous STS frame is always an even
                              number. The second bit of the BIP-8 is used in
                              exactly the same way, except that it performs a
                              check on the second bit of each byte. For
                              concatenated frames, BIP-8 byte is defined in the
                              first STS-1 frame only.

1. Management Summary

   1.1. Introduction

   This Statement of Work is appended to the Agreement for Transition Services
   dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
   Service Corporation and its affiliates and shall be governed by the terms and
   conditions thereof. The services described herein shall be provided by GTE
   Data Services Incorporated ("GTEDS") for a period of the earlier of the date
   of completion of the work or December 31, 2000.

   1.2  Executive Summary

   Genuity desires to continue the ongoing development of a Global Network
   Infrastructure Integrated Testing ("GNI Integrated Testing") solution with
   GTEDS. The GNI Integrated Testing solution, as referenced herein in more
   detail, enables Genuity to access information regarding their network
   elements and use that information for checking for circuit degradation and
   for forecasting network failure. Genuity has determined development of such a
   solution involves skill sets and core competencies currently not internally
   available. Using another provider for the development of the GNI Integrated
   Testing solution could delay Genuity's current business plans. Accordingly,
   Genuity desires to complete the work as contained herein within the stated
   time frame, and GTEDS desires to continue this work during this transition
   period.

2. Scope of SOW

   In the case of the GNI, Nortel's INM element management system already
   provides alarm correlation to the level of add-drop-multiplexers within a
   Sonet ring, a very valuable attribute. The focus of integrated testing would
   be built on this foundation to provide end-to-end views of customer circuits,
   that is, go one level up and provide correlation across the entire circuit.
   At the same time, Sonet elements are rich in diagnostic capabilities, and
   these could be exploited to provide specific repair recommendations in an
   automated fashion. Finally, data would be accessible from the network
   elements to explore circuit degradation, that is, attempt to anticipate
   failures before they occur. The last topic is exploratory in that pre-emptive
   detection of network failure has long been an elusive goal in the circuit
   switched world and needs to be established as valuable in a packet data
   network.

                                                                     Page 1 of 7
<PAGE>

                                                   SOW - GNI Integrating Testing
--------------------------------------------------------------------------------

     To this basic Sonet orientation would be added the diagnostic capabilities
     of ATM switches. For this we would leverage our existing expertise in frame
     relay. Diagnosis of frame relay circuits has just been prototyped in SSCFI
     and will become a field capability this spring. An extension to incorporate
     fault diagnosis of ATM switches is relatively straightforward and something
     that we must accomplish anyway as ADSL backhaul evolves from frame to ATM
     within GTE's network.

     It is proposed that work proceed in three phases; requirements gathering,
     prototype development and finally a fielded solution.

     Phase I - Requirements
     ----------------------
     This work requires a reasonable amount of debriefing of GNOC staff as to
     the their present methodologies for performing testing when circuits and/or
     circuit elements go into alarm. In an automated system, the goal is to
     replicate what an experienced technician can do, not necessarily to be more
     accurate than a technician but certainly to be much faster. Opportunities
     for automation would be identified as would areas for fully exploiting
     network element capabilities, both Sonet elements and ATM switches.

     Phase II - Prototype
     --------------------
     The requirements phase would be followed by a design, planning and a
     prototype. At this point it is not clear whether a SSCFI based
     implementation with its current rule-based engine or another approach with
     more modern web-based technologies would be appropriate.

     Phase III - Fielded System
     --------------------------
     The goal is to provide a fully supported, field system. The department has
     a long history of successful service assurance systems which have become
     integrated into GTE's business processes. The aim would be the same for a
     GNI integrated testing solution.

     2.1. Dependencies

     The timeline presented in this SOW is tentative and subject to receiving
     the ATP according to the date in milestone 1 above. Any delays in receiving
     the ATP will result in changes in the delivery dates accordingly.

     High-level business needs include:
     Rapid fault isolation of customer circuits.
     Reduced training needs for GNOC personnel.
     Enhanced network reliability.
     Path for automated trouble ticket resolution.

                                                                     Page 2 of 7

1. Management Summary

   1.1. Introduction

   This Statement of Work is appended to the Agreement for Transition Services
   dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
   Service Corporation and its affiliates and shall be governed by the terms and
   conditions thereof. The services described herein shall be provided by GTE
   Data Services Incorporated ("GTEDS") for a period of the earlier of the date
   of completion of the work or December 31, 2000.

   1.2. Executive Summary

   Genuity desires to continue the ongoing development of a Customer Network
   Management ("CNM") solution with GTEDS. The CNM solution, as referenced
   herein in more detail, enables Genuity's customers to access information
   regarding their accounts. Genuity has determined development of such a
   solution involves skill sets and core competencies currently not internally
   available. Moving the development of the CNM solution to another provider
   could delay Genuity's current business plans. Accordingly, Genuity desires to
   complete the work as contained herein within the stated time frame, and GTEDS
   desires to continue this work during this transition period.

2. Scope of Work

   This document describes the proposed work to analyze and develop requirements
   for a Customer Network Management solution that enables GNI's customers to
   access information pertaining to the services purchased from GNI. This CNM
   solution is expected to provide the customer information such as status of
   relevant orders, services, and the network, information that is collected
   and/or produced in the areas of performance, fault, and configuration
   management.

   The GNI infrastructure provides several services, including ATM and Private
   line offerings to CLECs and other large customers. This customer-set demands
   "High-Value" products and responsiveness is very important in this
   relationship. Providing the customer access to key information and metrics
   that relate to the services sold by GNI is critical to achieve an optimal
   relationship and to earn the customers' loyalty. Such access to information
   could be tiered, the lowest tier matching what our competition provides.
   Premium features can then

                                                                     Page 1 of 9
<PAGE>

   be charged appropriately. Another view is to organize the information
   corresponding to the Network and Service domains. For example in the Service
   Assurance process Network problems are reported to the Network Management
   systems as Fault Information. Correlating this with the Provisioning
   Information that is generated during the Fulfillment process (Provisioning
   information) enables partitioning of the Fault information for a circuit or
   customer. The challenge in CNM is to make available to the customer
   information in a timely and secure fashion.

   2.1. High Level Business Needs

   Business needs include:

   Order Status Review
   Service Change Requests and Status
   Service Level Agreement management
   Usage billing management
   Network capacity planning
   Status of all circuits for a customer
   PM, fault, and Security statistics
   Mean Time To Repair (MTTR)
   Circuit monitoring and troubleshooting
   Measurement of network availability, cell-counts, dropped cell counts,delay
   Network usage information
   Secured access to the information via web to the customers

   2.2. Approach

   The four steps to systematically define Genuity's CNM offering for private
   line and ATM customers are listed below.

   2.2.1 Competitive Benchmarking

   This will be a "hands on" effort to learn what Genuity's private line and ATM
   competitors are offering in the CNM space. We will work with GTE business
   units (Genuity, GTECC) that buy private line and ATM circuits from
   competitors. Through them, we gain access to competitive CNM offerings and
   answer the following questions:

   - What are the CNM features being offered by Genuity's private line and ATM
     competitors?
   - Which of these features do GTE business units find useful?
   - What is the minimum set of CNM features that Genuity must support to be
     viewed as having a legitimate offering in the private line and ATM market?
   - What features might differentiate this new CNM offering?

                                                                     Page 2 of 9
<PAGE>

   2.2.2 Information Architecture

   The competitive benchmarking activity will determine what is desirable in a
   CNM offering. The information architecture activity will determine what is
   possible. Genuity's CNM offering for private line and ATM services will make
   information that is stored in GNI's OSS's available to customers via a web
   interface. For all of this information to be published, we need to know

   - Which OSS manages the information to be published?
   - What support does the OSS have for partitioning information by customer and
     circuit, and limiting access to information by customer?
   - What is the Web interface to the OSS?

   There are a number of Genuity initiatives that deal with the information and
   OSS's that will be involved with the CNM offering, including:

   - CIA/Data Mart/Data Warehouse/EAI projects
   - the Web-based interface to TBS PSR project
   - the BS OE/Sales Bundling of Services projects
   - the CSO infrastructure enhancements project

   We will examine the OSS's that store the information to be published, as well
   as related systems and initiatives, to design an overall information
   architecture for the CNM offering. This includes the overall flow of
   information from OSS's to customers via the CNM web site how the facilities
   of each OSS are used to partition information by customer how the web
   interfaces of the OSS's are used, and what new web interfaces are needed to
   integrate the information.

   2.2.3 GNI CNM Design

   Once we know what the market wants in a CNM offering, and how much it will
   cost to include various information sources, we will design the CNM offering
   for private line and ATM services. This includes specifying

   - what information will be included
   - how the information will be organized and navigated
   - the "look and feel" of the web site
   - security features to ensure privacy of information

   The design will include screen mock ups. The target audience for this design
   is service line management for Genuity's private line and ATM services.

   2.2.4 System Requirements Specification

   Once service line management has approved the CNM offering, it must be
   translated into a system requirements specification that will govern the
   development and deployment of the CNM offering. The target audience for this
   specification is the organization that will develop the CNM system.

                                                                     Page 3 of 9

1    Management Summary

     1.1.  Introduction

     This Statement of Work is appended to the Agreement for Transition Services
     dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
     Service Corporation and its affiliates and shall be governed by the terms
     and conditions thereof. The services described herein shall be provided by
     GTE Data Services Incorporated ("GTEDS") for a period of the earlier of the
     date of completion of the work or December 31, 2000.

     1.2.  Executive Summary

     Genuity desires to continue the ongoing development of a Global Network
     Infrastructure Intelligent Network Management Reporting and Analysis ("GNI
     INM") solution with GTEDS. The GNI INM solution, as referenced herein in
     more detail, enables Genuity to customize reports regarding network fault
     and performance management data. Genuity has determined development of such
     a solution involves skill sets and core competencies currently not
     internally available. Using another providor for the development of the GNI
     INM solution could delay Genuity's current business plans. Accordingly,
     Genuity desires to complete the work as contained herein within the stated
     time frame, and GTEDS desires to continue this work during this transition
     period.

2.   Scope of SOW

     2.1.  Scope/Objective:

     This document describes the proposed work to analyze and develop
     requirements for an Intelligent Network Management reporting and analysis
     solution that enables GNI NOC network managers, administrators and planners
     to obtain highly customizable historical report in the areas of fault and
     performance management. The proposed solution will identify the need for
     online analytical processing (OLAP) as well as data visualization of the
     network status.

     The GNI Network and Services: GNI is predominantly in the "Wholesale"
     business, providing ATM and Private Line services to CLECs and other large
     customers. GNOC is the

                                                                     Page 1 of 8
<PAGE>

                                    SOW - GNI Intelligent Reporting and Analysis
--------------------------------------------------------------------------------

     central facility for monitoring and controlling GNI network. GNOC keeps
     track of the real-time status of the network, performing fault management
     (FM) and performance management (PM) functions. It receives both alarm and
     network performance data information, which requires processing, analysis,
     and reporting. It's essential for GNOC to be able to have historical and
     general view of the status of the network in order to provide better
     service to the customers. Monitoring network not only requires monitoring
     individual real-time alarms (in the case of Fault Management), but requires
     NOC staff to be able to understand the network in a general sense (for
     example, how the network for a particular region behaved over a certain
     period of time). It's critical for GNOC staff to be able to tell what has
     been going in a particular part of the network (say a region or a network
     element), and how it's likely to behave in the near future. This capability
     takes network-monitoring technology a step forward by introducing the
     concept of general network monitoring (in contrast to individual alarm
     monitoring) and the concept of network status history (in contrast to real-
     time status information). The Intelligent network management reporting and
     analysis study proposed in this statement of work (SOW) addresses these
     problems and provides requirements for implementation of such
     functionality.

     High Level business needs include:

     .  Historical reporting and analysis on GNI network fault and performance
     .  Intelligent network planning
     .  Predicting and preventing costly faults/failures
     .  Expedited problem diagnosis and improve operational efficiency
     .  Ensured compliance with service level agreements (SLA)
     .  Enhanced network service offerings
     .  Measures for operator performance

     2.2.   Approach:

     The five-step approach to systematically define GNI's requirements for
     intelligent network management reporting and analysis are listed below. The
     milestones and the level of effort are listed later. While all five steps
     are listed, this SOW is only expected to apply to the first two steps.

     2.2.1. Requirements Gathering:
     This phase of the project involves cooperation between Genuity/GNI and GTE
     and addresses the following questions:

     .  What business problems the product in mind is supposed to solve?
     .  Is a central global alarm repository a requirement?
     .  Level of PM and FM data correlation?
     .  How long does the data warehouse needs to keep information in history?
     .  What are the requirements for data granularity?
     .  Report types and categories.
     .  OLAP capability requirements.
     .  Data visualization capability requirements.
     .  Data warehousing performance requirements.
     .  Availability and scalability requirements
     .  Etc.

                                                                     Page 2 of 8

--------------------------------------------------------------------------------

     2.2.2. Data sources and definition of interfaces:
     The intelligent network management reporting and analysis data warehousing
     target solution is a decision-support tool. It receives FM and PM
     information from variety of data sources over a number of interfaces. This
     phase of the project will identify these FM and PM data streams/sources.
     Interfaces to operational systems will be defined which might include
     requirements for modifications to the operational systems themselves. The
     following issues will be addressed:

     .  What FM and PM applications are used by GNI? What are the interfaces,
        data format, volume, etc?
     .  How do we get the data from these operational systems? Are there any
        requirements for modifications to GNI PM and FM operational systems?
     .  Interfaces to GNI PM and FM operational systems will be defined

     2.2.3. System architecture and DB schema design:
     Once we are clear about where and how to get network management data
     streams, the next task is to come up with a reliable and scalable system
     architecture, which will meet data warehousing performance requirements.
     The data warehouse database schema is to be designed in this phase.
     The following components of overall system architecture and DB schema will
     be considered and recommended:

     .  Database engine to be used for data warehouse as well as other
        components of the system (i.e. reporting engine, etc.)?
     .  Scale of the problem
     .  Application hardware
     .  Network bandwidth and metrics requirements.
     .  Data compression requirements.
     .  Define and recommend an optimal overall application and reporting
        subsystem architecture.
     .  Data warehouse schema design - determine fact tables and dimension
        tables, determine indexes to build, determine partition strategy, etc.

     2.2.4. User Interface Design:
     After the system architecture and database schema have been determined, GTE
     Labs needs to work closely with GNI to design the web based user interface
     and develop mockup screens as part of overall Intelligent Reporting and
     Analysis application. This phase of the project has the following tasks:

     .  Identify all reports that GNI would like to have
     .  Identify required commercial of the shelf (COTS) software components.
     .  Determine the "look and feel" and develop mock up screens.

     2.2.5. System Requirements Specification:
     Once GNI management has approved proposed IRA architecture and
     functionality it must be translated into a system requirements
     specification that will govern the development and deployment of
     Intelligent Reporting and Analysis capability for GNI. The target audience
     for this specification is the organization that will develop the IRA
     application.

                                                                     Page 3 of 8

    This Statement of Work is appended to the Agreement for Transition Services
    dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
    Service Corporation and its affiliates and shall be governed by the terms
    and conditions thereof. The services described herein shall be provided by
    GTE Data Services Incorporated ("GTEDS") for a period of the earlier of the
    date of completion of the work or December 31, 2000.

    1.2.  Executive Summary

    Genuity desires to continue the ongoing development of an end-to-end
    response time measurement tool ("SiteRadar") solution with GTEDS. The
    development, as referenced herein in more detail, enables Genuity to
    determine network response times end-to-end to determine if service level
    commitments are being met. Genuity has determined development of such a
    solution involves skill sets and core competencies currently not internally
    available. Using another provider for the development of the solution could
    delay Genuity's current business plans. Accordingly, Genuity desires to
    complete the work as contained herein within the stated time frame, and
    GTEDS desires to continue this work during this transition period.

2.  Scope of SOW

    2.1.  Business Needs

    Genuity requires tools to measure the end-to-end quality of the services
    being provided customer, particularly when quantitative service level
    agreements are involved. In addition, it needs diagnostic tools that can
    identify and isolate problems either after they have been reported or,
    preferably, prior to being perceived by customers. This includes the need
    for a tool able to measure the response time of Web sites hosted by Genuity
    and distinguish the contributions of networks, servers, and cache systems to
    the download time. Such a tool would measure the response time of Web
    hosting customers as perceived by end-users. If placed at locations within
    the Genuity network, it could also be used as a diagnostic tool to identify
    problems. The tool should provide the duration of relevant events such as
    redirect times and component loading times. It is very important that the
    tool be completely under the control of Genuity so that it can be customized
    and used to Genuity's requirements and all the raw data is available for
    analysis by any method Genuity determines.

                                                                     Page 1 of 9

                                                           SOW-SiteRadar Project
--------------------------------------------------------------------------------

    2.2.  Approach

    Solution Capabilities

    GTEDS will work with Genuity to develop SiteRadar, a tool for measuring the
    performance of Web sites. SiteRadar will enable Genuity to both measure Web
    site download times as perceived by end-users, and also distinguish the
    effects on performance of networks and servers. It will also be a tool for
    the evaluation and tuning of cache systems with the potential for real-time
    operation if needed.

    The high-level architecture for SiteRadar is shown in Figure 1. The major
    components are:- Remote agents that issue requests against the Web sites to
    be tested and measure the response times. - -- The remote agents can be
    located at any geographic location inside or outside of Genuity's network.-
    A master agent that configures the remote agents (e.g., sets URLs to be
    tested and testing schedules), collects the data from the remote agents, and
    stores the data in a database.- A relational database for storing the
    measurements.- A reporting engine that provides user-configured reports via
    a Web browser client.The capabilities of SiteRadar include:

    - Remote measurement agents can be located outside Genuity network to
    determine response seen by end-users.- Remote measurement agents can be
    located inside Genuity network (e.g., POPs, data centers) to isolate effects
    due to other networks, segments of Genuity's network, and servers.-
    Measurements include total download time as well as the duration of
    significant events such as times to download individual components of page.-
    Potential for real-time operation to diagnose or correct problems.- Data are
    stored in a database and are available for any analysis methodology.- Web
    client is used for viewing reports.-Report can be configured by users.

    Four types of reports are currently available:
       Time History - Response time plotted for a specified duration of time
       Performance by Agent - Response time measured by each remote agent
       Component Graph - Time to download each page componentSite Availability -
       Percentage of time Web site is in possible states

    Solution Development Process
    ----------------------------
    A prototype of SiteRadar has already been developed and can be used to
    gather user feedback and requirements for the production system. GTEDS
    proposes a phased development process in which successive versions of
    SiteRadar will add new functionality. This approach reduces time risk by
    providing the highest priority features in a short period of time, and
    reduces functionality risk by allowing the evaluation of a working system to
    drive the next set of capabilities. The phased development process will be
    highly interactive with Genuity owners and users of SiteRadar in order to
    provide the feedback and priorities needed for successive versions of the
    tool.

    In the first phase, GTEDS will provide Genuity both a working prototype of
    SiteRadar for evaluation together with a draft requirements document
    containing prospective features for version 1.0 of the production system.
    Based upon its priorities and assessment of the prototype, Genuity and GTEDS
    will jointly determine the final requirements for version 1.0.

    In the second phase, version 1.0 of the production system, containing
    additional critical functions, will be developed and deployed at an agreed
    upon date in early 2Q2000. In

                                                                     Page 2 of 9
<PAGE>

                                                           SOW-SiteRadar Project
--------------------------------------------------------------------------------

    subsequent phases GTEDS will provide enhancements adding capabilities
    according Genuity's priorities.

    Genuity will provide the production machines and will purchase the
    appropriate third party software licenses (e.g., Allaire ColdFusion) needed
    for deployment.

    Project Activities

    Requirements Gathering
    ----------------------
    GTEDS has developed a working prototype and prepared a preliminary list of
    requirements for SiteRadar. Genuity and GTEDS will collaboratively finalize
    the requirements for the production version. Genuity has the option to use
    and evaluate the prototype to provide input to the requirements gathering
    activity or for any special projects that may occur prior to the
    availability of the production system. The requirements will be used for
    detailed system design and project planning.

    Software Development
    --------------------
    The master and remote clients for the prototype system are written in Java
    for platform independence. The remote clients will be built to closely
    emulate the behavior of standard Web browsers. Oracle is used for the
    database and ColdFusion is used to generate dynamic pages for the reporting
    engine. A conventional Web browser serves as both the reporting and
    administrative client. This approach has been successful for the prototype
    but can be changed if Genuity has special requirements. GTEDS will generate
    detailed technical specifications based upon the requirements, design and
    develop the production version of SiteRadar, and test it for compliance with
    the requirements.

    Project Planning
    ----------------
    The SiteRadar project will be undertaken by the Operations Systems
    Laboratory (OSL) of GTEDS. OSL development projects use an internal software
    development process called TopGun to improve software quality and
    development efficiency. TopGun requires that all major phases of the
    development process be documented and reviewed.

    Statement of Work

    Phase 1 - Prototype Evaluation and Requirements Gathering
    ---------------------------------------------------------

    Subsequent Phases - Ongoing Support, Enhancements, Upgrades and Releases
    ------------------------------------------------------------------------
    GTEDS will provide enhancements to Side Radar based on feedback from users
    and additional capabilities identified as important by Genuity. GTEDS will
    attempt to provide new functionality in incremental updates if this is
    advantageous to Genuity and can be accommodated by the development team. One
    or more subsequent phases will occur in 2H2000. The schedule of
    enhancements, upgrades, and releases will be mutually determined based on
    the priorities identified by Genuity after requirements are finalized.

                                                                     Page 4 of 9

     1.2.  Executive Summary

     Genuity desires to continue the ongoing development of a network capacity
     planing, routing and data mining ("IP Modeling") solution with GTEDS. The
     development, as referenced herein in more detail, further enables Genuity
     to provision network connections using extensions of current network
     capacity planning and routing tools. Genuity has determined development of
     such a solution involves skill sets and core competencies currently not
     internally available. Using another provider for the development of the IP
     Modeling solution could delay Genuity's current business plans.
     Accordingly, Genuity desires to complete the work as contained herein
     within the stated time frame, and GTEDS desires to continue this work
     during this transition period.

2.   Scope of SOW

     2.1.  Scope/Objective
     The work to be performed under this SOW can be broken down into two parts:
     directly linked, and complementary, to earlier contracts already in place
     for BART 3.x, and SCPT Phase 1 delivery, and needed to ensure that both
     BART and SCPT continue to evolve as the technology and business practices
     in GNI evolve.

                                                                     Page 1 of 9

                                          SOW - Modeling for IP, ATM, SONET/DWDM
--------------------------------------------------------------------------------

     2.1.1.   BART 3.x related work
     The short-term effort under this SOW concentrates on developing the
     required functionality in the following two areas that are planned for 4/00
     and 7/00 releases.
     .   Expanded failure analysis.
     .   Capacity modeling and routing for SVCs.

     The more forward looking areas will deal with new and alternative means of
     trunk provisioning that GNI plans to evaluate and possibly use, such as:
     ATM over DWDM, ATM trunk routing on protection channels of SONET rings. It
     will also study the potential benefits of integrating SCPT (SONET planning
     system) with BART. The output of this work will be incorporated in later
     releases of BART.

     Short-term
     .   Development of new analytical models of Ascend failure restoration
         processes based on bandwidth and bumping priorities. The new models
         will address circuit rerouting based on bandwidth and bumping
         priorities as defined in a circuit record and will allow negative
         bandwidth trunks for non-real time circuits with 0 bumping priority
         (see NavisCore ATM Configuration Guide, Priority Routing, Appendix E).
         This is intended to go into BART 3.0 (Expanded failure analysis)
     .   A new set of models will also be developed for SVC planning module.
         These models will address the stochastic nature of SVC traffic in a
         manner similar to those in place for planning the PSTN. This is
         intended to go into BART 3.1 (Capacity modeling and routing for SVC
         circuits)
     .   Development of a new restoration algorithm that can analyze very
         complex network behavior during restoration in a reasonable amount of
         time. The problem to overcome here is a domino-like effect of bumping
         the lower priority circuits to accommodate the higher priority ones
         (Expanded failure analysis)
     .   Developing models and algorithms for building traffic matrices from
         historical billing data for SVC service (Capacity Modeling and routing
         for SVCs).

     Next steps
     .   Development of new modeling, evaluation and optimization methods for
         cost-effective ATM trunk provisioning directly over DWDM systems.
         Modeling DWDM protection methods and their interaction with ATM
         restoration methods. Extending BART failure analysis to include the
         described interactions.
     .   Developing new evaluation methods for ATM trunk provisioning using
         SONET protection channels. Modeling link failures and their impact on
         ATM circuits. Extending BART failure analysis to include the described
         impacts.
     .   Study the benefits of integration of BART with SCPT. This capability
         will provide a two-way communication between the tools. Anticipated
         benefits to BART users include ability to automatically populate BART
         databases by using the up-to-date data on SONET and optical layers and
         ATM trunk provisioning on them. Anticipated benefits to SCPT users is
         the ability to extract from BART planned trunks, thus providing more
         accurate demand, usage and routing information for ATM traffic.

                                                                     Page 2 of 9

--------------------------------------------------------------------------------

     SCPT Phase 1 & 2 related work

     The short term concentrates on:
     .   Analysis and design phases for the routing and demand segmentation
         features (Phase 1)

     .   Analysis and design phases for automated methods to update baseline
         network description and inventory data. In Phase 1 this is a manual
         step but automated methods will be critical to ensure accuracy of the
         baseline network picture in SCPT. The work would include analysis of
         data interface capabilities to bring system configuration and
         connectivity information from Nortel's Data Mining/SONET Planner Tool
         to SCPT, as well as the possibility of a data feed from Smallworld
         (Phase 2).

     .   Design and evaluate methods to make relevant capacity information
         easily accessible to other parts of the organization. This would
         include web-enabled information/report publishing and sharing (Phase
         2).

     Next steps
     The more forward-looking work will focus on:

     .   modeling requirements to accommodate DWDM planning and circuit
         provisioning directly on DWDM layer

     .   changes required to SCPT design and data model to support circuit
         routing on SONET protection channels, for example ATM circuits routed
         over SONET protection capacity

     .   assessment of the potential methods and benefits of integrating SCPT
         with BART (see BART write-up above)

     .   analysis and design of data interface capabilities to bring network
         usage data from TBS to SCPT. Also develop requirements to reconcile
         existing SCPT demand records and TBS records.

     .   more advanced demand routing algorithms that focus on load balancing,
         or other criteria.

                                                                     Page 3 of 9

                            GTE Data Services, Inc.
                                      And
                            Genuity Solutions Inc.

                       Genuity Spam Fingerprinting Plan

   This SOW along with all attachments hereto shall be considered GTE Data
              Services, Inc. Proprietary/Confidential Information

1.   Management Summary

     1.1.     Introduction

     This Statement of Work is appended to the Agreement for Transition Services
     dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
     Service Corporation and its affiliates and shall be governed by the terms
     and conditions thereof. The services described herein shall be provided by
     GTE Data Services Incorporated ("GTEDS") for a period of the earlier of the
     date of completion of the work or December 31, 2000.

     1.2.   Executive Summary

     Genuity desires to continue the ongoing development of a tool ("SpamCheck")
     to parse complaints regarding unsolicited e-mail ("spam") from other
     complaints. The development, as referenced herein in more detail, further
     enables Genuity to handle a number of e-mail complaints received among
     which include complaints regarding spam. Genuity has determined development
     of such a solution involves skill sets and core competencies currently not
     internally available. Using another provider for the development of the
     SpamCheck tool could delay Genuity's current business plans. Accordingly,
     Genuity desires to complete the work as contained herein within the stated
     time frame, and GTEDS desires to continue this work during this transition
     period.

2.   Scope of SOW

     2.1.   Business Needs:

     Genuity Customer Service Center (CSC) employs full-time staff to analyze
     and respond to a large volume of complaints that involve Genuity's
     customers and/or network. More than 30,000 email complaints per month are
     received. Each complaint requires review, logging, trouble ticket review,
     correlation with other complaints, response to the complainant,
     categorization, validation, distribution to appropriate staff, and
     resolution. CSC has developed an effective manual process for handling
     email complaints, but the volume of complaints is large and growing. Hence
     a tool for automating a significant portion of the manual process is
     needed. Since the majority of complaints involve the use of Genuity's
     network for delivering unsolicited email or spam, the tool development
     focuses on spam complaint processing.

                                                                    Page 1 of 11

                                                  SOW - Spam Fingerprinting Plan
--------------------------------------------------------------------------------

     2.2.   Approach:

     Genuity CSC developed a set of requirements for a spam "fingerprinting"
     system in June 1998. It has also documented a set of manual procedures used
     to process and classify spam. It has a large set of archived spam
     complaints that are available for use in system design and testing. Based
     on these procedures and samples, GTEDS has created a prototype system
     called SpamCheck(TM). The SpamCheck prototype retrieves email from a POP
     server, parses the email to extract the critical identification features,
     stores both the raw and extracted information in a relational database, and
     provides a web interface for reviewing the results and performing queries
     against the database. In preliminary testing, approximately 1000 sample
     spam complaints have been processed by the system. This prototype has been
     presented to CSC personnel and has been useful in clarifying some of the
     functional requirements. A detailed requirements document is being prepared
     jointly by Genuity and GTEDS, and will be used for more detailed project
     planning.

     Due to the pressing backlog of spam complaints, there is an immediate need
     to deploy a subset of the required functionality. GTEDS plans to configure
     a version of the prototype that has only known functional features enabled
     during the month of February. This prototype may not correctly parse all
     spam complaints because of the many variations of email forwarding and
     embedding--and in some cases mail header corruption--that occur in
     practice. At least until a fully-tested version 1 is released, an 80-20
     coverage rule will be the processing target, i.e., the system should handle
     the majority of the "easy" cases and postpone the special case processing
     until the majority cases are fully handled.

     Run Utilities                      top
                                        ---

     There are several common utilities used to trace the route of a Spam
     message or locate the domain or IP address of its sender. For the best
     results, it is advisable to run several utilities because they may have
     access to different databases. By running more than one utility, you can
     verify the Spam sender address more reliably, and on occasion, if one
     utility does not locate the Spammer, the other utility may be more
     successful.

     The following utilities are provided with SpamCheck:

          nslookup                      top
                                        ---

          Nslookup is a program to query Internet domain name servers. Nslookup
          has two modes: inter-active and non-interactive. Interactive mode
          allows the user to query name servers for information about various
          hosts and domains or to print a list of hosts in a domain.
          Non-interactive mode is used to print just the name and requested
          information for a host or domain.

          traceroute                    top
                                        ---

          The traceroute output shows the different "hops" an IP message took to
          reach its destination. Each route the message crosses is referred to
          as a hop.

          DIG                           top
                                        ---

     The main functional areas of SpamCheck include:

         1.0    Email retrieval: Automatic retrieval of email complaints from a
                POP server
         2.0    Email Distribution: Differentiating non-spam related complaints
                and forwarding these to another email address
         3.0    Parsing and extraction: parsing of the email into at least three
                pieces: 1) internal tracking header and body, 2) complainant
                header and body, 3) spam sample header and body. Each of these
                pieces is further parsed to extract specific fields that are
                needed for analysis

                                                                    Page 2 of 11

--------------------------------------------------------------------------------

         4.0    Trouble ticketing: each complaint needs to be associated with
                either an existing or new trouble ticket. Genuity uses the
                Vantive trouble ticketing system today, and an interface between
                SpamCheck and Vantive will be needed.
         5.0    Analysis utilities: additional information about the spam source
                may be gathered as needed by automatically invoking utilities
                such as traceroute, nslookup, whois, and dig. Other utilities
                include remote host clock validation and hex internet address
                conversion.
         6.0    Storage: Both the raw and extracted information needs to be
                stored in a database. Information gathered by utilities should
                also be stored in the database
         7.0    Classification Rules: A set of rules is used to categorize the
                spam and determine how it should be resolved and what response
                to the complainant should be sent.
         8.0    Presentation and Query Web Interface: The results of spam
                complaint processing will be presented through a web interface,
                and the ability to query the database will be provided.
         9.0    Workflow: Each spam complaint involves a number of user
                processing steps. The system will track progress and provide a
                user interface that fits the sequence of tasks that the spam
                analyst performs.
         10.0   Administration: Facilities for supporting installation,
                configuration, backup, extensions to certain parameters
                (keywords, categories), form letters, etc. will be provided
                through a web interface. The administrative interface also
                includes a regression testing capability.
         11.0   Online documentation: user and administrative documentation will
                be available through web pages.

                Genuity will provide the on-site test and deployment machines
                and will purchase the appropriate third party software (e.g.,
                Allaire ColdFusion) licenses needed for deployment. Genuity will
                administer and manage the on-site equipment. Labs will work
                closely with Genuity to insure successful deployment and use of
                the system.

     2.3.   Project Activities:

     .   Requirements Gathering:
     Genuity CSC developed a set of requirements for a spam "fingerprinting"
     system in June 1998. It has also documented a set of manual procedures used
     to process and classify spam. It has a large set of archived spam
     complaints that are available for use in system design and testing. Based
     on these procedures and samples, Labs has created a prototype system called
     SpamCheck(TM). A detailed requirements document is being prepared jointly
     by Genuity and GTEDS, and will be used for detailed project planning.
     Further requirements may be identifies as user feedback from system use is
     obtained.

     .   Software Development
     The prototype system has validated the use of ColdFusion web server and
     Oracle database. The software for the system is currently a combination of
     Perl, Java, and ColdFusion scripts.

     .   Testing
     There are thousands of samples to select test cases from. Developing a set
     of test cases that provide reasonable coverage over the thousands of spam
     complaints is an ongoing issue. Creating a definitive set of test cases is
     a prerequisite for developing a quantitative performance metric for the
     system. We have instrumented the prototype to provide a

                                                                    Page 3 of 11

--------------------------------------------------------------------------------

     regression test facility for the parsing and extraction modules so that
     test cases can be stored in the database and used to validate upgrades to
     the system.

     .   Deployment
     CSC has provided an NT machine for deploying the prototype. The use of this
     machine for production will need evaluation. During the prototype
     deployment, Labs will perform integration with the POP server,
     installation, and configuration. In subsequent releases, a streamlined
     installation script may be provided.

     .   User Evaluation
     As spam analysts gain experience with the system, Labs expects to collect
     feedback on functionality, ease of use, bugs, test cases, etc. in order to
     improve the system.

     .   Support
     Labs plans to have the development team perform the support function until
     the SpamCheck system has been completed. After that, the Operations Systems
     Laboratory has a support team and in the long term a maintenance agreement
     with the OSL support team can be arranged.

     .   Integration
     The primary integration work anticipated is with Vantive, to permit
     SpamCheck to retrieve existing tickets and create a new ticket if
     necessary. Integration with Vantive requires the review and approval of the
     Genuity IS organization.

     .   Project Planning
     OSL development projects use an internal software development process
     called TopGun, which covers the entire software lifecycle. The purpose of
     the TopGun process is to improve software quality and development
     efficiency.

                                                                    Page 4 of 11

     2.5.   Milestone Schedule:

     Phase 1
            We propose a delivery date of the prototype as soon as possible, but
            by February 28, 2000 at the latest. The prototype has the following
            limitations:
            .  does not perform categorization
            .  no automated distribution function
            .  may not extract all fields correctly
            .  the query interface will be present
            .  dig may not be available
            .  no integration with Vantive
            GTEDS (through its subcontractor) has integrated a regression
            testing facility and plans to collect test cases during phase 1.

                                                                    Page 5 of 11

                                                  SOW - Spam Fingerprinting Plan
--------------------------------------------------------------------------------

            Labs expects the review of the detailed requirements document to be
            completed during phase 1. There will be user training and evaluation
            sessions as needed for the prototype.

       Phase 2 - Release of SpamCheck Version 1.0
            Delivery dates for Phase 2 will be based upon Genuity priorities,
            but will be in 2Q2000. We will attempt to provide new functionality
            in incremental updates if this has advantages to Genuity and can be
            accommodated by the development team.

            .  Version 1.0 will be a fully functional system delivered sometime
               in 2Q2000 including:
            .  categorization
            .  distribution
            .  partial population of the regression testing facility
            .  the 20% special parsing/categorization cases will be deferred
               based on priorities set by Genuity

            Integration with Vantive is unlikely in this version.

       Phase 3 - Ongoing Support, Enhancements, Upgrades and Releases
            This phase will include the Vantive integration, which depends on
            appropriate arrangements with Genuity IS. These arrangements will be
            coordinated by Genuity CSC. We propose a 2H00 timeframe for phase 3.
            We expect to do further enhancements to the system based on feedback
            from users and increased number of test cases that will be run
            through the system.

            The schedule of enhancements, upgrades, and releases will be
            mutually determined based on the priorities identified by Genuity
            after requirements are finalized.

     2.6.   Change Control

     2.11.  Acceptance Criteria

     GTEDS will ensure that the following criteria are met in the delivered
     product:

     GTEDS will provide a complete and integrated design that will provide
     functionality as specified in the Requirement and Conceptual Solution
     Document, as of the date of the approved SOW.

     GTEDS will retain documented functionality of previous Releases and SOWs
     where the functionality is unchanged.

3.   Special Considerations
     The following items have been identified as issues that affect the delivery
     of SpamCheck.
     .   The Vantive integration depends on coordination with IS. Labs has
         performed and deployed integration with other trouble ticketing systems
         (e.g., Remedy, for Genuity GNI).
     .   The 80-20 target is not based on quantitative testing, we may find that
         there are more or less volume of special cases than anticipated
     .   Evolution of spammers' techniques may introduce spam cases that are
         more difficult to analyze and match

                                                                    Page 8 of 11

1.   Management Summary

     1.1. Introduction

     This Statement of Work is appended to the Agreement for Transition Services
     dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
     Service Corporation and its affiliates and shall be governed by the terms
     and conditions thereof. The services described herein shall be provided by
     GTE Data Services Incorporated ("GTEDS") for a period of the earlier of the
     date of completion of the work or December 31, 2000.

     1.2. Executive Summary

     Genuity desires to continue the ongoing development of enhancements for
     network capacity planning ("BART") with GTEDS. The development, as
     referenced herein in more detail, further enables Genuity to reroute
     circuits owing to data traffic and bandwidth commitments. Genuity has
     determined that continued development of BART involves skill sets and core
     competencies currently not internally available. Moving the continuation of
     BART development to another provider could delay Genuity's current business
     plans. Accordingly, Genuity desires to complete the work as contained
     herein within the stated time frame, and GTEDS desires to continue this
     work during this transition period.

2.   Scope of SOW

     2.1. Scope/Objective:

     Expanded failure analysis

     Overview : A new version of the tool will expand failure analysis
     capabilities to include the following cases of failures:

     .  Circuit rerouting based on bumping and bandwidth priorities
     .  Link (layer 1)
     .  Front (processor) card (layer 2)
     .  Node (layer 1)
     .  Catastrophic failure (simultaneous failures of all NE in the same
        location)

     Failure analysis functions

                                                                     Page 1 of 9
<PAGE>

                                                 SOW - Enhancements for BART 3.0
--------------------------------------------------------------------------------

     Circuit rerouting based on bumping and bandwidth priorities

     BART 2.1 restoration algorithm does not take into consideration circuit
     bandwidth and bumping priorities when performing restoration of failed
     circuits treating all circuits as if they have the same priorities. A new
     version of the failure analysis algorithm will perform circuit rerouting
     based on these priorities thus modeling Ascend restoration process
     including negative bandwidth trunks for non-real time circuits with 0
     bumping priority (see [1]) in a more precise manner.
     Link failure analysis

     The tool will study the impact of simultaneous failures of all links
     between two locations. Only the links that are not SONET protected will
     assume to fail. Failure of unprotected links will affect the trunks that
     are routed through at least one of these links. BART will use two sources
     of information to find the routes:

     .  TRUNK ROUTE EXCEPTION table that specifies the route directly.
     .  Default (minimum length route) for the trunks that are not in TRUNK
        ROUTE EXCEPTION table

     Simultaneous link failure will be modeled as a simultaneous failure of all
     the affected trunks.

     Front card failure analysis:
     The tool will study the impact of front card failures on trunks as follows:

     .  For each slot (one-to-one correspondence is assumed between slots and
        processor cards) on each switch the tool will find all trunks that are
        not inter-card protected.
     .  Front card failure will be modeled as a simultaneous failure of all
        these trunks.

     Layer 1 node failure analysis:
     The tool will study the impact of individual node failures. The following
     cases will be considered:

     a) a node is a part of a system that is not a BLSR ring. Node failure is
        modeled as simultaneous failures of its adjacent links.
     b) a node is a part of a BLSR ring and the node is not interconnected with
        other systems. Node failure is modeled as a failure of all layer 2
        switches connected to the node.
     c) a node is a part a BLSR ring and the node is interconnected with another
        system using matched node protected t-link. Failure of the node is
        modeled as a failure of all layer 2 switches connected to the node.
     d) a node is a part a BLSR ring; the node is interconnected with another
        system using unprotected t-link. Modeled as a failure of all layer 2
        switches connected to the node plus all trunks using unprotected t-link.

     Catastrophic POP failure impact analysis:
     This failure is modeled as a simultaneous failure of all switches and nodes
     collocated in a given location.

     SVC enhancement
     Description: SVC's will necessitate additional work to support Capacity
     Planning. Currently BART calculates the equivalent bandwidth of each PVC
     and then uses OSPF routing to

                                                                     Page 2 of 9

                                                 SOW - Enhancements for BART 3.0
--------------------------------------------------------------------------------

     determine if the circuit can be routed over ATM trunks during normal and
     failure situations. If PVCs are like private circuits, SVCs are like phone
     calls, and the impact of SVCs on our network have to be handled like phone
     calls, using projections based on historic measurements. To get historic
     measurements it will be required that the billing system be able to provide
     a file of information to the BART server with the following elements in
     each record for each completed call;
     .  From/to Switch CLLI/LPort
     .  From/to Date/Time
     .  A-Z/Z-A CoS/PCR/SCR/MBS/MCR

     Using the tool the user will be able to perform the following functions:
     analyze SVC billing data, convert them into bandwidth equivalent PVC
     circuits, and reserve equivalent bandwidth in the GNI ATM cloud for SVCs.

                               Statement of Work
                                    Between
                            GTE Data Services, Inc.
                                      And
                            Genuity Solutions Inc.
                                  To Provide:
                          SCPT Production Deployment

    This SOW along with all attachments hereto shall be considered GTE Data
                 Services Proprietary/Confidential Information

1.   Management Summary

     1.1. Introduction
     This Statement of Work is appended to the Agreement for Transition Services
     dated _______by and between Genuity Solutions Inc. ("Genuity") and GTE
     Service Corporation and its affiliates and shall be governed by the terms
     and conditions thereof. The services described herein shall be provided by
     GTE Data Services Incorporated ("GTEDS") for a period of the earlier of the
     date of completion of the work or December 31, 2000.

     1.2. Executive Summary

     Genuity desires to continue the ongoing deployment of a network routing
     simulation ("IP Modeling") solution with GTEDS. The deployment, as
     referenced herein in more detail, further enables Genuity to simulate
     network routing to obtain need data to better understand their network
     operations. Genuity has determined deployment of such a solution involves
     skill sets and core competencies currently not internally available. Using
     another provider for the deployment of the IP Modeling solution could delay
     Genuity's current business plans. Accordingly, Genuity desires to complete
     the work as contained herein within the stated time frame, and GTEDS
     desires to continue this work during this transition period.

2.   Scope of Work

     2.1. New Functionality

     2.1.1 Data processing and import/export capabilities to support Jason
     Whitler's demand routing simulation and to perform required computations
     for the subsequent "Network Segment Fill Analysis".

     2.1.2 Analyze, design, and develop Demand Segmentation features. (Ref: GNI
     CP requirements DF28, DF15, DF16, DF18, DF19, and DF21) The goal of these
     requirements is to automatically process each raw demand into pieces for
     layers 1A, 1B, and/or 2, and to provide appropriate homing arrangements.

                                                                     Page 1 of 8

                                                SOW - SCPT Production Deployment
--------------------------------------------------------------------------------

     2.1.3 WCDR/CODA mapping and reconciliation. (This is to update demand and
           circuit status.)

     2.2.  Enhance Database Capabilities

     2.2.1 Design and develop capabilities to ensure upgradability and
     continuity in production DB.
     (This ensures that as new features are added to the tool and the db schema
     is changed, we can keep track of what db is being used currently and how to
     migrate it to the new db)

     2.2.2 Develop the capability to extract demand data from one DB and merge
     into another DB.
     (This will allow planners to work with local versions for independent
     analysis and then provide capability to merge the shared data, with
     appropriately defined rules for the merging and updating)

     2.2.3 Provide Activity Logging feature for every major user edit (e.g.,
     creating a new system, deleting a circuit). More data export capabilities.
     Data will not be locked in a closed system.

     2.3.  Enhance Deployment Platform and Performance

     2.3.1 Upgrade PowerBuilder and Sybase runtime engines to enable web
     interface in the future.

     2.3.2 Performance enhancements will be handled in future phases.

     2.4.  Data Population

     2.4.1 Update baseline network, physical inventory, and capacity demand in
     SCPT database.

     2.5.  Testing, Documentation and Support

     2.5.1 Testing and fixing before the rollout.

     2.5.2 User Guide, training material, and online help.

     2.5.3 On-site training.

     2.5.4 Support throughout the year 2000 to add minor enhancements and fix
     bugs.

                                                                     Page 2 of 8

1.11 Special Considerations

     Monthly Performance Meetings
     ----------------------------

     National SAP Support Center and Genuity will attend a planned monthly
     Performance Review meeting with Commercial Services Account Management. The
     primary purpose of these meetings will be review the monthly reporting
     package and discuss account status.

     The objectives of the meeting will include, but not be limited to:

     .    Review of reporting package
     .    Forecast of customer workload
     .    General Issues

     Addition Of New Solution Environments
     -------------------------------------

     If there are significant changes in processing requirements or customer
     environments, the measurements contained in this Statement Of Work are
     subject to revision based on mutual agreement of GTEDS and Genuity. When a
     new solution configuration environment is added, its performance will be
     tracked, but not included in the rating mix until the system has been
     running in production for two (2) months and support documentation has been
     provided by the Genuity to GTEDS.

2.0  Compensation Authorization

2.1  Compensation Terms

     The monthly billings for this SOW will consist of four parts.

     Part 1 - Data Center Infrastructure -The funding authorized for this
     portion of the Statement of Work is a total price for the hardware and data
     center infrastructure (a.k.a. AM/FM). The hardware and infrastructure have
     been established to support a range of users between 700 - 1,000
     (consistent with current usage patterns). Genuity has also chosen to add
     two optional hardware configurations to the base support, high availability
     and disaster recovery. The total support is comparable to the existing
     services received today and is consistent with the current service level
     agreement. This portion will be billed on a monthly basis of $149,042.

       provide monthly reporting against each service level to Genuity. Each
       service level will have a target range of performance. These terms are

            Goal     - Grade of service that GTEDS will be striving for
            Target   - Grade of service that should initially be expected
            Baseline - Grade of service that will require investigation, an
                       action plan and improvement to at least the target level.

       If GTEDS's performance falls to the baseline more than two (2)
       consecutive months or two months in the previous six (6) months, GTEDS
       will, as part of the standard service offering, conduct an investigation
       into cause of the service problem. GTEDS will present Genuity with an
       action plan within in thirty (30) days that corrects GTEDS' performance
       to the target level. Correction to the target must be completed within
       thirty (30) days after the plan is presented and mutually agreed to.

5.   Problem Reporting and Management

 5.1      Problem Reporting Procedures

               The Genuity telephones the National SAP Support Center (NSSC) at
               (214) 285-4000 to report all problems. The NSSC provides support
               Monday through Friday from 07:00 to 19:00 Central Time except for
               GTE defined holidays. All problems reported are documented in the
               standard trouble-tracking tool, INFOMAN.

               After hours, weekends and holidays calls are routed to the GTE
               National Support Center (NSC) for first level problem resolution
               and dispatch if necessary. All calls are documented in the
               standard trouble-tracking tool, INFOMAN. Upon receiving the call,
               the NSC records the problem and begins troubleshooting based on
               the severity level as shown in the table below.

               The NSC tries to resolve problems on first touch. If the NSC
               dispatches a problem to another support provider, it nevertheless
               continues to manage the problem until it is resolved. The support
               group responding to the problem will negotiate a resolve-by date
               and time. Elapsed repair time begins when a problem is reported
               to GTE NSC and ends when it is resolved.

               The goal of the GTE NSC is to answer business partner calls as
               quickly as possible and to resolve as many problems as possible
               at the NSC level. Responsiveness is measured by the Automated
               Call Distribution (ACD) system. Monthly reports are available
               upon request.

 5.2      Response to Problem/Severity Codes

               All problems reported by SAP R/3 users or support personnel will
               be logged into the problem tracking system and will be identified
               as incidents. Severity Levels for all problems/incidents will be
               established by the problem reporter based upon business
               requirement demands. The following table outlines support
               response guidelines by severity level:

                                                                    Page 3 of 27

</TABLE>

               Note: During the initial investigation of a critical problem,
               helpdesk support staff may be responsible for contacting the user
               to acknowledge SAP support is working the issue.

               Automated escalation timeframes are defined and managed in the
               GTE Trouble System Contact DataBase (TSCDB). If the primary on-
               call person does not respond to a page in 30 minutes, he is paged
               a second time, and a 15-minute wait period takes place. If there
               is no response, the secondary on-call support person gets paged
               similarly twice, at 15-minute intervals. If there is still no
               response, the SAP Crisis Manager will be contacted. At any time,
               the business partner can manually escalate a problem by calling
               the NSC.

5.3   IR Resolution/Customer Commitment Dates

               When an Incident Report (IR) is submitted, the SAP support team
               will contact the customer according to the requirements outlined
               in section 5.2. Customer commitment dates for IR resolution will
               be negotiated using the following guidelines:

6.       Disaster Recovery

               Disaster recovery planning is intended to protect a company's
               business processes during an extended period of system
               unavailability. Under the terms of this service level, the
               Genuity SAP R/3 system will be recovered at the hotsite within 4
               days of a catastrophic disaster declaration. The Shared Service
               Center in Coppell, TX will be maintained as the recovery hotsite.
               Recovery would be accomplished using the most recent backup tapes
               available in off-site storage. The disaster recovery plan for the
               data processing recovery will be maintained and updated by
               National SAP Support Center personnel. Annual disaster recovery
               simulations will be conducted to ensure the validity of all
               recovery plans.

               Genuity personnel will be responsible for identifying interim
               business procedures to be used in the event of a major disaster.
               These procedures will be used during the timeframe the production
               system recovery is underway.

               Genuity personnel will be responsible for developing and
               maintaining appropriate business continuity plans.

7.   Minor Enhancements

               For non-IR related work, as described in section 4.1 of Appendix
               A, the customer has requested a pool of hours be established for
               minor enhancement requests. The intent of these hours is to
               provide for quick turn around on small requests without going
               through the formal statement of work process required for larger
               development and enhancement projects. Examples of the types of
               requests that might flow through this pool are: ad hoc business
               reports, new reports, changes to existing reports, minor
               enhancements, or ad hoc technical analysis reporting.

                                                                    Page 5 of 27
<PAGE>

7.1   Initiating a Request

               To achieve optimal use for these hours, a list of approved
               requesters will be filed with the NSSC. All requests will flow
               through the SLA account management focal point. The SLA focal
               point will provide the requestor with an estimate within two (2)
               business days outlining the hours required to complete the
               request. The estimate will be a full process estimate for all SAP
               resource groups required to fulfill the request. Work will not
               begin until approval from the requestor is received.

7.2   Tracking of Hours

               The minor enhancement pool hours will be tracked and accounted
               for separately, so the customer can determine usage. Resource
               charges will be billed on a time and materials basis at the rates
               specified in the contract.

                                                                    Page 6 of 27

8.    Performance

 8.1      Measures

               This section of the SLA contains specific performance objectives,
               which are to be used for the SAP R/3 production environments. The
               National SAP Support Center will monitor these metrics to ensure
               these objectives, performance standards, and cost expectations
               are being met.

               GTEDS will perform the services requested in a Statement Of Work
               with the intention of meeting the service level objectives
               outlined in this Service Level Agreement. GTEDS will provide
               monthly reporting against each service level to Genuity. Each
               service level will have a target range of performance. These
               terms are defined as follows:

                     Goal      - Grade of service that NSSC will be striving for

                     Target    - Grade of service that should initially be
                               expected

                                                                    Page 7 of 27

<PAGE>

                     Baseline   - Grade of service that will require
                                investigation, an action plan and
                                improvement to at least the target level.

                 If GTEDS's performance falls to the baseline more than two
                 (2) consecutive months or two months in the previous six (6)
                 months, GTEDS will, as part of the standard service
                 offering, conduct an investigation into cause of the service
                 problem. GTEDS will present an action plan within in thirty
                 (30) days that corrects the GTEDS's performance to the
                 target level. Correction to the target must be completed
                 within thirty (30) days after the plan is presented and
                 mutually agreed to.

                 Each of the performance measures listed in the table above
                 is defined in the paragraphs that follow.

          8.1.1  System Availability
                 It is expected that GTEDS will make every effort to meet the
                 stated performance standards for system availability. The
                 percentage of scheduled time the system is available will be
                 tracked and reported in the standard performance reports.

                 Exceptions to the above measures are as follows:

                 .  Downtime caused by customer will not be reflected in the
                    downtime statistics

                 .  Network outages caused by the Genuity network provider will
                    not be reflected in the downtime statistics

                 System availability is defined as the accessibility of the
                 hardware and system software residing at the GTE facility. The
                 system is considered available if a customer-authorized user
                 can access it in order to carry out the desired business
                 function. GTEDS responsibility will be limited only to
                 monitoring, managing and trouble diagnosis of those network
                 elements for which it has direct control.

          8.1.2  Unplanned Outages

                 An unscheduled outage is defined as any period of time in which
                 the system is unavailable during scheduled operational hours.
                 GTEDS will endeavor to make the computer processing capability
                 available for use by Genuity twenty-four (24) hours per day,
                 seven (7) per week, except for the time necessary to perform
                 preventative maintenance and operating system upgrades.

          8.1.3  Planned Maintenance Downtime

                 Planned Maintenance downtime includes the time periods for
                 preventative maintenance and operating system upgrades.
                 Maintenance schedules will be communicated in advance to the
                 Genuity, and mutually negotiated if such time interferes with
                 GTEDS' ability to meet customer commitments, or, if the
                 customer requires system availability at that time. Maintenance
                 scheduled with less that 24 hours notice would be counted as
                 downtime unless Genuity requests the maintenance.

          8.1.4  Mean time to Repair

                 Mean time to repair is the average amount of time required
                 to resolve a system outage.

          8.1.5  Mean time between Failure

                 Mean time between failure is the average elapsed time between
                 system outages.

                                                                    Page 8 of 27
<PAGE>

           8.1.6    IRs Installed on Time

                    The total number of incidents installed into production
                    environments on or before the Genuity commitment date is
                    divided by the total number of incidents containing a
                    Genuity commitment date during the report period.

           8.2.2    Outage Root Cause Notification Email

                    Following any SAP outage, the results of a Root Cause
                    Analysis will be emailed to Genuity within two business
                    days.

                    If an SAP outage of up to 2 hours occurs, a root cause
                    notification will be emailed within 24 hours, containing the
                    cause of, and procedure for correcting, such failure.

           8.2.3    Performance Metrics

                    A Monthly SAP performance report will be created by GTEDS,
                    reviewed at the monthly service review meeting and published
                    on an SAP web server.

           8.2.4    Post Mortem Review

                    If an outage lasts longer than 2 hours, all involved service
                    providers and Genuity will participate in a post-mortem
                    review to discuss the outage's root cause and to outline a
                    plan to prevent a recurrence of the problem.

           8.2.5    Management Reviews

                    GTEDS will schedule and manage meetings with Genuity to
                    review the performance criteria defined in the SLA. These
                    meetings will occur Monthly or at some other interval as
                    agreed to by GTEDS and Genuity.

                                                                    Page 9 of 27

 11.    SLA Review

                  The SLA is renewed by default on an annual, budget-year basis,
                  with no action required by either party. The focal points for
                  GTEDS and Genuity may review this SLA annually to determine

6.0      Disaster Recovery Planning (DRP)

                    Any disaster which strikes a data processing or business
                    facility will produce serious effects on the business, the
                    service provider, and customers of the service or business.
                    The time required to return to normal operations following a
                    disaster depends upon establishment, maintenance, testing,
                    and execution of well organized and effective recovery
                    plans. Disaster Recovery Planning is a business issue to be
                    addressed via a team effort requiring participation of the
                    providers of the service, the users of the service, the
                    functional owners of the systems, and other appropriate
                    departments.

         6.1      Business Recovery

                    Plans, implements, and operates business-justified levels of
                    protection/recoverability for critical business processes
                    and enablers in the event of a disaster at any critical work
                    site. The balancing of protection and recovery costs versus
                    exposure risk is at the heart of the process. In this
                    manner, it is assured that appropriate, business-justified,
                    affordable, and effective measures are in place should a
                    disaster strike any critical work site.

                    Planning for recovery of business process sites assumes that
                    such sites have been adversely affected by some event and
                    that the functions normally performed at that site must be
                    assumed in another location. Such planning assumes that
                    personnel resources may also be unavailable. Due to the
                    geographic and operational variations for each site plan, a
                    plan is required for each individual business site.

         6.2      Data Processing Recovery

                    Identifies critical business requirements for disaster
                    recovery of individual application systems and classifies
                    the application system based on the identified recovery time
                    requirements. Research is then performed to identify a
                    business-justified, cost-effective disaster recovery
                    solution strategy that satisfies the required recovery
                    timeframe and all other identified business requirements.
                    Disaster recovery solution strategies may include any or a
                    combination of the following recovery strategies:

                      a. Vendor hotsite recovery hardware strategy
                      b. Internal GTEDS recovery hardware strategy
                      c. Quick-ship recovery hardware strategy at vendor hotsite
                         or internal GTEDS location
                      d. Recovery hardware identified, obtained, and installed
                         to be used at the time of a disaster

                    Recovery strategies form the basis for the development,
                    implementation, and testing of an application system
                    disaster recovery plan, which includes:

                      a. Notification and mobilization of required personnel
                      b. Detailed listing of data files backed up and stored
                         offsite
                      c. Documented infrastructure requirements such as
                         platform, operating system, layered software, network,
                         etc.
                      d. Documented step-by-step instructions for application
                         system recovery
                      e. Description of test requirements for scheduled annual
                         end-to-end testing of disaster recovery capability

                      Maintenance procedures to ensure all components of the
                      documented DR plan are kept current.
                                                                   Page 19 of 27

         The monthly billings for this SOW will consist of four parts.

         Part 1 - Data Center Infrastructure -The funding authorized for this
         portion of the Statement of Work is a total price for the hardware and
         data center infrastructure (a.k.a. AM/FM). The HR/Payroll hardware and
         infrastructure have been established to support a range of users
         between 500 - 800 (consistent with current usage patterns). The total
         support is comparable to the existing services received today and is
         consistent with the current service level agreement. This portion will
         be billed on a monthly basis of $7,382. For the Data Center
         Infrastructure, Genuity will be billed as a prorated share of total
         employees using the platform. Initial estimates are based on 3,500
         Genuity employees out of a base of 90,000 total employees (3,500/90,000
         or 3.89%).

         Part 2 - Production Support -The funding authorized for the production
         support portion of the Statement of Work is defined below at a per seat
         per month rate with volume discounts applied. Payment will be made
         based on the average number of SAP Named Users during each month.

         Genuity representing 50 of

                                  Page 4 of 9
<PAGE>

          those. Genuity will be billed at the system price per seat based on
          the total system users. Current bill rate with 50 out of the 800
          planned users would be $170.00.

         all licenses necessary for use of such software, pay any associated
         fees negotiated with GTEDS for running such software for Genuity and
         pay any costs related to obtaining required consents needed by GTEDS to
         use such software for Genuity's benefit. Genuity shall be responsible
         for all costs associated with Genuity provided third party software.
         The estimated license fee(s) are to be determined.

3.0      Service Level

         GTEDS will perform the services requested in the Statement Of Work with
         the intention of meeting the service level objectives for the
         Production SAP R/3 system as outlined in the SAP R/3 Service Level
         Agreement attached to the Information Technology Services Agreement.
         GTEDS will provide monthly reporting against each service level to
         Genuity. Each service level will have a target range of performance.
         These terms are defined as follows:

             Goal     - Grade of service that GTEDS will be striving for
             Target   - Grade of service that should initially be expected
             Baseline - Grade of service that will require investigation, an
                        action plan and improvement to at least the target
                        level.

         If GTEDS's performance falls to the baseline more than two (2)
         consecutive months or two months in the previous six (6) months, GTEDS
         will, as part of the standard service offering, conduct an
         investigation into cause of the service problem. GTEDS will present
         Genuity with an action plan within in thirty (30) days that corrects
         GTEDS' performance to the target level. Correction to the target must
         be completed within thirty (30) days after the plan is presented and
         mutually agreed to.

1.1      Introduction
         This Statement of Work is appended to the Agreement for IT Transition
         Services dated ________________________, 2000 by and between GTE
         Service Corporation and its affiliates ("GTESC") and Genuity Solutions
         Inc. ("Genuity") and shall be governed by the terms and conditions
         hereof. The services described herein shall be provided by Genuity for
         a period of up to 12 months effective upon the Effective Date of the
         Agreement for IT Transition Services. This Statement of Work may not be
         renewed.

Management Summary

1.1    Introduction

       This Statement of Work is appended to the Agreement for IT
       TransitionServices dated March 31, 2000 by and between Genuity Solutions
       Inc. ("Genuity") and GTE Service Corporation and its affiliates
       (hereinafter collectively referred to as "GTE" or "GTO" or "GTE
       Technology Organization") and shall be governed by the terms and
       conditions thereof. The services described herein shall be provided by
       Genuity for a period of the earlier of one year from the Effective Date

1.2    Executive Summary

       The physical build out of the computing infrastructure needed for the GTE
       Technology Organization to be self-sufficient and to perform business as
       usual will not have been completed by the merger date. GTE Technology
       Organization has maintained that, in order to continue its regular
       business operations, they will need continuing network, server, voice,
       desktop and help desk support services provided by the Genuity
       Information Technology organization in Cambridge, MA. During the
       transition period, physical separation activities will be completed to
       enable the GTE Technology Organization to be able to support itself on
       it's own computing infrastructure, owned and maintained by them, as well
       as put in place their own support staff.

1.21   Order of Precedence

       Any inconsistency in this document shall be resolved by giving priority
       and precedence in the following order:

          Engineering
          -----------

          Technology, Solutions, and Deployment organization will provide
          consulting expertise in evaluating and recommending new solutions for
          new and upgrades to H/W, S/W, Networking, Server Infrastructure. TSD
          will provide consulting expertise in evaluating and developing GTE
          Genuity Desktop/laptop H/W standards and selection.

          Problem Reporting
          -----------------

          All problems will be reported to the Cambridge Genuity Help Desk. The
          Cambridge Genuity Help Desk will log and track problems using Vantive.
          Problems not reported through Cambridge may not be logged and tracked
          properly and will not be subject to service restoration or
          availability targets.

          A service outage is the unexplained and unplanned outage of a
          scheduled service such as a system, network, or application in which
          the customer is unable to continue processing. These outages are
          further defined as the loss of service when no redundancy for that
          service is available. Application related outages not directly as a
          result of system hardware/software problems or operations errors are
          not to be considered a service outage for the purposes of this
          Statement Of Work.

          Application outages are the responsibility of Genuity where Business
          Applications are deemed to be supported through outsourcing.

          Application outages are the responsibility of Genuity where Business
          Applications are deemed to have limited support and only not related
          to application software.

          Application outages are the responsibility of GTO where outages are
          deemed to be at the application level.

          In the event of an unscheduled service outage, notification to GTO
          will be performed according to customer escalation procedures. Genuity
          will provide to GTO information regarding the nature, scope, expected
          duration and steps to be taken to resolve the outage.

                                                                    Page 7 of 23

          1.33      Service Support Environmental Thresholds
                    ----------------------------------------

          Baseline Support Threshold
          --------------------------

          Service levels reflected in the pricing structure are predicated on
          supporting a baseline user community and operational environment as
          follows:

          .    GTO baseline personnel supported = 1,423
          .    Problem Reports/month = 2,302/mo
          .    Service Requests/month = 1,265/mo
          .    Major moves of 10 to100 people per year = 40
          .    Normal ProductionChange Requests = 60

          Stretch Support Threshold
          -------------------------

          Service levels reflected in the pricing structure include the ability
          to stretch to accommodate growth during the contract period to a
          maximum supported user community and operational environment as
          follows:

          .    GTO stretch personnel = 1,679
          .    Problem Reports/month = 2,596/mo
          .    Service Requests/month = 1,492/mo
          .    Major moves of 10 to 100 people per year = 48
          .    Normal Production Change Requests = 75

                                                                    Page 8 of 23
<PAGE>

          Additional hardware would also be required to support stretch service
          levels as follows:

               .    Incremental mail server increase = 1 per every additional
                    200 users over baseline 1,423 users.
               .    Incremental infrastructure server increase = 1 per every
                    100 additional users over baseline 1,423 users.
               .    Network switch ports and phone ports required are based on
                    increments of 24 ports/card.

          The growth of any threshold metrics beyond the levels identified in
          this section will require the submission of a Change Request Form (See
          Attachment A) documenting the anticipated change to the environment.
          In response, the Change Request Form will be reviewed, evaluated,
          priced, and returned to Genuity for approval prior to execution.

</TABLE>

          The SLA is considered met if GTO is notified that the Genuity has
          begun problem identification and is working towards resolution
          according to the following parameter:

          Severity 0 events - within one business hour
          Severity 1 events - within one business hour
          Severity 2 events - within 8 business hours
          Severity 3 events - within 3 business days

          Relative to Server Hardware, the SLA is considered met if GTO is
          notified that any 3/rd/ party hardware vendor has begun problem
          identification and resolution within 4 business hours.

          Relative to Desktop Hardware, the SLA is considered met if GTO is
          notified that any 3/rd/ party hardware vendor has begun problem
          identification and working towards resolution within 8 business hours.

Scheduled  Maintenance

Time frames for a scheduled maintenance window are as follows:

 .    Non-Disruptive Maintenance Window
     -   Consistent with current timings and frequencies for hot backups,
     exports, etc
 .    Disruptive Maintenance Window
     -   Consistent with current timings and frequencies
     -   Cold backups of GTO Server files may be performed. Disruptive
     activities (such as code installs) may be performed. Existing change
     management processes and notifications must be adhered to.

System unavailability during this period will not be considered an outage or
charged against the system availability target. A Genuity Change Request will be
discussed and coordinated with GTO if maintenance is required outside the
scheduled maintenance window and be coordinated by the AMC.

Additional maintenance will be negotiated with Genuity on an as needed basis. If
GTO concurs with the time frame(s) requested, it will not be considered an
outage.

                                                                   Page 11 of 23
<PAGE>

Service Provider Management Review Meetings - Quarterly
-------------------------------------------------------

Genuity will attend planned Service Provider Management Review meetings with GTO
quarterly. The primary purpose of these meetings will be to discuss:

 .    Response/Coverage: Relative to hardware/software down time, resource
     availability, or general coverage.
 .    Follow-through: Relative to what is being done about lingering open
     problems.
 .    Critical Solution: Existing or potential services that may impact GTO/GTO
     service.
 .    Service Provider Assessment: What GTO can do to help Genuity better serve
     GTO.
 .    General comments and/or questions.
 .    Schedule next meeting.

1.91     Service Requests

         Routine processor and network related service requests will be
         submitted to the IT Help Desk via written or electronic correspondence.
         If there is a question of whether a request is routine, or non-routine,
         it will be processed as a non-routine request until otherwise
         determined. Routine service requests will be documented and a log will
         be kept noting the:

            .  Person making the request
            .  Date request was made
            .  Description of request
            .  Date request was completed

         Routine service requests will be processed as agreed upon by all
         parties using the matrix in Section 2.4.

1.92     Special Considerations

         Addition Of New Solution Environments
         -------------------------------------

         If there are significant changes in processing requirements or GTO
         environments, the measurements contained in this Statement Of Work are
         subject to revision based on mutual agreement of Genuity and GTO. When
         a new solution configuration environment is added, its performance will
         be tracked, but not included in the rating mix until the system has
         been running in production for two (2) months and support documentation
         has been provided by GTO to Genuity.

         Asset Transfer
         --------------

         Assets relating to the facilities, such as but not limited to routers,
         cables, and circuits, will be transferred to the party who is the owner
         or lessor of record for the facility during the transition period but
         no later than 4/30/00.

         GTO retains the networks: 128.33.0.0/16 (portable, with GTO having
         right to advertise) and 128.89.0.0/16 (portable, with GTO having right
         to advertise). A member of GTO will be listed with ARIN as the POC for
         the networks.

                                                                   Page 12 of 23
<PAGE>

         All servers currently support GTO customers will be transferred to GTO
         during the transition period but not later than 4/30/00.

1.93     Change Control

         Changes to this Statement Of Work can be requested by either GTO or
         Genuity using the Change Control Request Form in Attachment A. The form
         is completed by the requesting party and submitted to the corresponding
         contact in the other organization for evaluation and/or approval. If
         approved, the Change Control Request Form is then sent to the Genuity
         Contract Manager for execution.

         Production Change Control

         Genuity will continue to provide the existing Genuity Change Management
         process to plan, communicate, coordinate, schedule, and review all
         changes to the production and development environments. This process
         includes a change control board, which reviews changes to the system,
         especially those, which require downtime for the system. The process
         adhered to must be consistent with, and maintain the standards as
         outlined in the document "Change Control Policies and Procedures,
         Version 1.3, dated August 17, 1998.

         The scope of the CM process encompasses the comprehensive management of
         all change activity within the end-to-end infrastructure of the
         production environments. This is to include changes to:

         .     Systems (Hardware, Software)
         .     Data
         .     Processing sites
         .     Networks
         .     Work centers
         .     Computing hardware
         .     All supporting infrastructure

         Prior to moving forward all changes to the production environment
         require a scheduled CMR review and approval by the CCB. CMRs (Change
         Management Reports) are created by Genuity and reviewed based on the
         established criteria. The Change Control Board represents all
         functional areas of Genuity; this group meets weekly to discuss all
         change management requests (CMRs). The Board allows for participation
         by agreed upon representative of GTO. GTO will have approval authority
         on changes which affect GTO's production environment.

2.0      Service Levels

         Genuity will perform the services requested in the Statement Of Work
         with the intention of meeting the service level objectives outlined
         below. Genuity will provide monthly reporting against each service
         level to the GTO Program Manager. Each service level will have a target
         range of performance. These terms are defined as follows:

               Goal      - Grade of service that Genuity will be striving for
               Target    - Grade of service that will be minimally acceptable
               Baseline  - Grade of service that will require investigation,
                           an action plan and improvement to at least the
                           target level.

         In addition, Severity Levels are used to measure the criticality of
         trouble tickets, which are created as a result of problems associated
         with operations. These severity levels are defined as follows:

               Severity Level 0 - Problems which cause critical
                                  impact to business functions of multiple
                                  customers. Justifies immediate attention
                                  and dedicated resources applying
                                  continuous efforts to resolve ASAP.
               Severity Level 1 - Problems which cause critical
                                  impact to the business function(s) of a
                                  single customer. Justifies management
                                  attention and dedicated resources applying
                                  continuous efforts to resolve ASAP.
               Severity Level 2 - Problems causing degradation of
                                  service resulting in impact to business
                                  function or customer. Impact justifies
                                  priority attention and application of
                                  resources to resolve in a timely manner.
               Severity Level 3 - Problems causing low impact to
                                  the business function(s) and customer(s).
                                  Requires timely resolution to minimize
                                  future impacts. Resources should be
                                  allocated in accordance with normal
                                  managerial planning and prioritization.

         The SLA is considered met if GTO is notified that the Genuity has begun
         problem identification and is working towards resolution based on the
         following criteria:

               Severity 0 events - within one business hour
               Severity 1 events - within one business hour
               Severity 2 events - within 8 business hours
               Severity 3 events - within 3 business days.

                                                                   Page 14 of 23
<PAGE>

         If Genuity performance falls to the baseline more than two (2)
         consecutive months or two months in the previous six (6) months, then
         Genuity will conduct an investigation into cause of the service problem
         and present the GTO Program Manager with an action plan within thirty
         (30) days that corrects the performance to the target level within
         sixty (60) days after the plan is presented and agreed to.

2.1      System and Network Availability

         2.11     System/On-line Availability

         System availability is defined as the accessibility of the hardware and
         system software residing at the Genuity facility. The system is
         considered available if a customer authorized user can access it in
         order to carry out the desired business function.

         An unscheduled outage is defined as any period of time in which the
         system is unavailable during scheduled operational hours. Genuity will
         endeavor to make the computer processing capability available for use
         by GTO twenty-four (24) hours per day, seven (7) per week, except for
         the time necessary to perform preventative maintenance and operating
         system upgrades. The time periods for preventative maintenance and
         operating system upgrades will be communicated in advance to GTO, and
         mutually negotiated if such time interferes with Genuity's ability to
         meet GTO commitments, or, if GTO requires system availability at that
         time

         It is expected that Genuity will make every effort to meet the
         following performance standards for both system availability and
         on-line availability. The percentage of scheduled time the system is
         available will be tracked. The goal, target, and baseline for
         performance reporting have been set as indicated below.

         -------------------------------------------------------------------
         Service Description   Service Level  Service Level  Service Level
                               Baseline       Target         Goal
         ===================================================================

         System Availability        98.4%      98.5 - 98.9%   99.5 - 100%
         -------------------------------------------------------------------

         Exceptions to the above measures are as follows:
          .     Downtime caused by customer will not be reflected in the
                downtime status
          .     Any application or database-related problems, not caused by
                Genuity, will not be reflected in the downtime statistics.

         2.12   Network Availability

         Network availability is defined as the accessibility of the network
         that provides connectivity between the customer location and the
         Genuity facility. The network is considered available if it can be
         utilized for the purpose of carrying out desired business functions. An
         unscheduled outage is defined as any period of time in which the
         network is unavailable during scheduled operational hours. The
         percentage of scheduled time the network is available will be tracked.
         The measure of performance is a composite percentage.

         Dial backup or other network measures in the event of a failure of the
         primary network provision does not constitute an outage. Degradation of
         network service during the use of a backup network solution does not
         constitute an outage.

                                                                   Page 15 of 23
<PAGE>

         VANTIVE Help Desk problem records will be created for all network
         outages and scheduled maintenance and will be used to compute actual
         network availability.

         Genuity will endeavor to make the telecommunications network
         capability, for which it is responsible, available for use by GTO
         twenty-four (24) hours per day, seven (7) per week.

         It is expected that Genuity will make every effort to meet the
         following performance standards for both system availability and
         on-line availability. The goal, target, and baseline for performance
         reporting have been set as indicated below.

         Network Availability       99.0%      99.1- 99.4%     99.5 - 100%
         ----------------------------------------------------------------------

         Exceptions to the above measurements are as follows:
           .   Downtime caused by customer will not be reflected in the downtime
               statistics
           .   Any application or database-related problem, not caused by
               Genuity, will not be reflected in the downtime statistics
           .   Pre-approved maintenance windows will not be reflected in the
               downtime statistics

2.2      Server Hardware / Operating System Service Restoration

         Server Hardware / Operating Service restoration is defined as the time
         required to resolve problems and restore service with the devices or
         the system software. Problems may be identified through system
         monitoring or user notification. The measure of performance is the
         average time required to resolve related problems.

         VANTIVE Help Desk problem records are created for all hardware and
         system software problems and will be used to compute resolution time.

         For a critical hardware problem, the target is considered met if GTO is
         notified that the hardware vendor has begun problem identification and
         resolution within four (4) hours.

                                                                   Page 16 of 23

         Additionally, status updates will be provided to the customer technical
         focal point. Frequency of updates will be agreed to during initial
         technical bridge call, and will continue until the problem is resolved.

2.3      Network Problem Resolution

         Network problem resolution is defined as the time required to resolve
         problems or faults with the network circuits / devices. Problems may be
         identified through monitoring or user notification. If a problem or
         nonconformity arises with the performance of the network, Genuity will
         determine the root cause and initiate a change or repair.

         The types of problems and non-conformities that can arise will be
         classified as either a critical or non-critical. For a critical network
         problem, the target will be considered met if the customer is notified
         of the event and Genuity or the network vendor has begun identification
         and is working towards resolution within the four (4) hour window.

         Dial backup or other network measures in the event of a failure of the
         primary network provision does not constitute an outage. Degradation of
         network service during the use of a backup network solution does not
         constitute an outage.

         The expected response time for these is listed below as well as the
         baseline/target/goal for performance reporting.

2.4      Change Requests and Requests for Special Processing

2.41     System Administration Turnaround Time

         System administration turnaround time is defined as the time required
         to successfully complete an administrative task once an approved
         request has been received. The measure of performance is the average
         time required to complete system turnaround tasks. VANTIVE Help Desk
         Change Management Request (CMR) will be created for all system
         administration requests and will be used to compute turnaround time.

<PAGE>

       Scheduled  Maintenance
       ----------------------
       Time frames for a scheduled maintenance window are as follows:

       .   Non-Disruptive Maintenance Window
           -    Consistent with current timings and frequencies for hot backups,
                exports, etc

       or charged against the system availability target. A Genuity Change
       Request will be discussed and coordinated with GTO if maintenance is
       required outside the scheduled maintenance window and be coordinated by
       the AMC.

       Additional maintenance will be negotiated with Genuity on an as needed
       basis. If GTO concurs with the time frame(s) requested, it will not be
       considered an outage.

       Service Provider Management Review Meetings - Quarterly
       -------------------------------------------------------
       Genuity will attend planned Service Provider Management Review meetings
       with GTO quarterly. The primary purpose of these meetings will be to
       discuss:

       .   Response/Coverage: Relative to application down time, resource
           availability, or general coverage.
       .   Follow-through: Relative to what is being done about lingering open
           problems.
       .   Critical Solution: Existing or potential services that may impact
           Genuity service.
       .   Service Provider Assessment: What GTO can do to help Genuity better
           serve GTO.
       .   General comments and/or questions.
       .   Schedule next meeting.

1.5.1  Service Requests

       Routine processor and network related service requests will be submitted
       to the IT Help Desk via written or electronic correspondence. If there is
       a question of whether a request is routine, or non-routine, it will be
       processed as a non-routine request until otherwise determined. Routine
       service requests will be documented and a log will be kept noting the:

           .   Person making the request
           .   Date request was made
           .   Description of request
           .   Date request was completed

       Routine service requests will be processed as agreed upon by all parties
       using the matrix in Section 2.2.

                                                                    Page 6 of 12
<PAGE>

1.5.2  Special Considerations

       Addition Of New Solution Environments
       -------------------------------------
       If there are significant changes in processing requirements or GTO
       environments, the measurements contained in this Statement Of Work are
       subject to revision based on mutual agreement of Genuity and GTO. When a
       new solution configuration environment is added, its performance will be
       tracked, but not included in the rating mix until the system has been
       running in production for two (2) months and support documentation has
       been provided by GTO to Genuity.

1.5.3  Change Control

       Changes to this Statement Of Work can be requested by either GTO or
       Genuity using the Change Control Request Form in Attachment A. The form
       is completed by the requesting party and submitted to the corresponding
       contact in the other organization for evaluation and/or approval. If
       approved, the Change Control Request Form is then sent to the Genuity
       Contract Manager for execution.

1.5.6  Compensation Authorization

       This work will be performed on a time and materials basis at the agreed
       labor rates. The estimated level of effort for the contract period is 1
       FTE. 0.5 FTE will be at the Sr. Developer rate, and 0.5 FTE will be at
       the Systems Engineer rate. This represents 954 hours each for this period
       of performance. Thus the total labor estimate is: $89,438 + $107,325 =
       $196,763.

2.0    Service Levels

       Genuity will perform the services requested in the Statement Of Work with
       the intention of meeting the service level objectives outlined below.
       Genuity will provide monthly reporting against each service level to the
       GTO Program Manager. Each service level will have a target range of
       performance. These terms are defined as follows:

               Goal       - Grade of service that Genuity will be striving for
               Target     - Grade of service that will be minimally acceptable
               Baseline   - Grade of service that will require investigation, an
                             action plan and improvement to at least the target
                             level.

       In addition, Severity Levels are used to measure the criticality of
       trouble tickets, which are created as a result of problems associated
       with operations. These severity levels are defined as follows:

               Severity Level 0 - Problems which cause critical impact to
                                  business functions of multiple customers.
                                  Justifies immediate attention and dedicated
                                  resources applying continuous efforts to
                                  resolve ASAP.
               Severity Level 1 - Problems which cause critical impact to the
                                  business function(s) of a single customer.
                                  Justifies management attention and dedicated
                                  resources applying continuous efforts to
                                  resolve ASAP.
               Severity Level 2 - Problems causing degradation of service
                                  resulting in impact to business function or
                                  customer. Impact justifies priority attention
                                  and application of resources to resolve in a
                                  timely manner.
               Severity Level 3 - Problems causing low impact to the business
                                  function(s) and customer(s). Requires timely
                                  resolution to minimize future impacts.
                                  Resources should be allocated in accordance
                                  with normal managerial planning and
                                  prioritization.

       The SLA is considered met if GTO is notified that the Genuity has begun
       problem identification and is working towards resolution based on the
       following criteria:

                                                                    Page 8 of 12
<PAGE>

               Severity 0 events - within one business hour
               Severity 1 events - within one business hour
               Severity 2 events - within 8 business hours
               Severity 3 events - within 3 business days.

       If Genuity performance falls to the baseline more than two (2)
       consecutive months or two months in the previous six (6) months, then
       Genuity will conduct an investigation into cause of the service problem
       and present the GTO Program Manager with an action plan within thirty
       (30) days that corrects the performance to the target level within sixty
       (60) days after the plan is presented and agreed to.

2.1    Application/Database Availability

       Application/Database availability is defined as the accessibility of the
       application or database residing at the Genuity facility. The system is
       considered available if a customer authorized user can access it in order
       to carry out the desired business function.

       An unscheduled outage is defined as any period of time in which the
       application or database is unavailable during scheduled operational
       hours. Genuity will endeavor to make the computer processing capability
       available for use by GTO twenty-four (24) hours per day, seven (7) per
       week, except for the time necessary to perform preventative maintenance
       and operating system upgrades. The time periods for preventative
       maintenance and operating system upgrades will be communicated in advance
       to GTO, and mutually negotiated if such time interferes with Genuity's
       ability to meet GTO commitments, or, if GTO requires system availability
       at that time.

       It is expected that Genuity will make every effort to meet the following
       performance standards for both system availability and on-line
       availability. The percentage of scheduled time the system is available
       will be tracked. The goal, target, and baseline for performance reporting
       have been set as indicated below.

       -----------------------------------------------------------------------
         Service Description    Service Level    Service Level   Service Level
                                Baseline         Target           Goal
       =======================================================================

         System Availability        98.4%        98.5 - 98.9%     99.5 - 100%
       -----------------------------------------------------------------------

         Exceptions to the above measures are as follows:
             .   Downtime caused by customer will not be reflected in the
                downtime status
             .   Any application or database-related problems, not caused by
                Genuity, will not be reflected in the downtime statistics.

                                                                    Page 9 of 12

purpose of this agreement, the term "affiliate" shall mean, with respect to any
person, any other person directly or indirectly controlling or controlled by, or
under direct or indirect common control with, such person.)

1.2  Lead Referrals.  Bell Atlantic may in its discretion refer to Genuity any
     --------------
offers to purchase or orders for (i) Genuity Services, or (ii) other services
offered by Genuity.  Genuity may in its discretion refer to Bell Atlantic any
offers or prospective offers to purchase the Genuity Services.  Any such
referral shall be made in accordance with applicable federal law and Section 2.4
of this Agreement.  If either party makes such a referral, the referring party
shall not, without advance notice to the other, independently pursue sale of the
referred opportunity with the potential customer unless the other fails to
pursue such referral within a reasonable time.  Genuity and Bell Atlantic shall
develop, no later than sixty (60) days

                                                                               1

Services at any time, upon forty-five (45) days' notice to Bell Atlantic, and to

days' notice to Bell Atlantic, provided that any such change, modification,
addition, removal or discontinuance shall be part of a general action by Genuity
with respect to the affected service and its retail and wholesale customers, and
shall not affect any Bell Atlantic End User contracts or valid Genuity quotes in
existence at the time of the Genuity notice.  Genuity specifically agrees to
continue to provide any Genuity Service and all related product support affected
by such change or discontinuance in accordance with the description of the
service and other terms and conditions in any Bell Atlantic End User contract
(provided that the End User contract is consistent with the Genuity Service
Description and other terms and conditions applicable at the time the contract
was signed) or valid Genuity quotes, for the duration of the term of such End
User contract or contract that results from such quote.

1.5  Service Schedules.   Each Service Schedule shall, at a minimum, include:

     ---------------------
Atlantic and/or to End Users at the rates and in

                                                                               2

this Agreement and the Service Schedules. Genuity shall also provide to Bell

other ancillary services and products as may be set forth in the Service
Schedules and this Agreement.

3.2  Operations.
     ----------

(a)  Genuity shall provide Bell Atlantic with mechanized, electronic access and
interfaces to those Genuity systems that support Bell Atlantic's marketing,
provisioning and support of the Genuity Services to End Users. This access and
interface capability shall apply to the following information and functionality:
(i) pre-sales information; (ii) ordering and provisioning; (iii) new products
literature; (iv) problem identification and isolation to assist Bell Atlantic in
its provision of level one End User support; (v) repair/trouble ticketing; and

incurred for system development and implementation necessary to comply with this
Section 3.2. Genuity may recover the cost of such development and implementation
through the prices it charges all customers for the Genuity Services, but shall
not otherwise charge Bell Atlantic any portion of such costs.

(b)  Promptly following the Effective Date, Genuity and Bell Atlantic shall each
designate by written notice a senior operations point of contact (O-POC) for
developing, implementing and maintaining business process interfaces throughout
the areas of each party's business affected by this Agreement. The parties shall
oversee the rollout of transaction processes for quotes, orders, provisioning,
customer care and billing across all Genuity Services. The shared design
principles shall be integration across all Genuity Services, customer
responsive, web based, scalable, and minimization of manual intervention. A
written process architecture shall be developed and maintained by both parties.
The first copy of this architecture shall be finalized within one hundred twenty
(120) days after the Effective Date. This shall be a dynamic document, available
online to both parties, that shall be the basis for identifying improvement
opportunities and for operations plans. The parties shall perform quarterly
reviews of these plans, with the O-POCs jointly managing the agenda and
attendees for such reviews. These reviews shall be alternately hosted by each
party at its facility of choice. Genuity shall work with Bell Atlantic to
develop and implement new support tools and process improvements with respect to
Bell Atlantic's purchase and sale of the Genuity Services. Genuity shall retain
all rights to tools and processes it develops, and, at its option, may implement
these tools and processes for other customers and resellers.

(c)  Bell Atlantic shall be responsible for the End User relationship. Genuity
shall provide access to documentation, training materials, and on-line support
tools that facilitate Bell Atlantic in providing level one support services for
its End Users. At Bell Atlantic's request and at Genuity's expense, Genuity
shall provide one time "train the trainer" sessions for level one support for
each product or service. These training sessions shall be held at Genuity
facilities for class sizes not to exceed 12 people, at mutually agreed times.
Bell Atlantic shall pay travel and living expenses for its attendees. At Bell
Atlantic's request, Genuity shall provide to Bell Atlantic quotes for fees on a
daily basis (plus travel and living expenses) for subsequent "train the trainer"
sessions, which sessions shall be held at Bell Atlantic facilities. Genuity
shall provide such subsequent sessions upon Bell Atlantic's acceptance of such
quote(s).

(d)  Genuity shall provide at its expense level two and level three support for
the Genuity Services. Bell Atlantic shall provide at its expense level one
support for the Genuity Services it resells. For maintenance of Genuity-supplied
customer premises equipment, Genuity shall act as service agent for Bell
Atlantic on Level II and Level III support situations. This service and support
shall be Bell Atlantic branded where practical. Genuity shall work cooperatively
with Bell Atlantic and/or Bell Atlantic customers for identification/isolation
of

                                                                               3
<PAGE>

difficult end-to-end or otherwise elusive problems. Genuity shall assume all
escalation and interface responsibilities for its suppliers.

(e)  The parties shall agree upon and publish written Bell Atlantic and Genuity
escalation and communication paths for the Genuity Services. These documents
shall be an addendum to the business process architecture discussed above.

(f)  Bell Atlantic and Genuity shall establish an operations review process to
review the performance measurements under the service level agreements for each
Genuity Service on a monthly basis, and establish action plans and "next steps"
as appropriate. These monthly reviews may be conducted by telephone or in face-
to-face meetings.

3.3  Business Practices.  Genuity and Genuity's representatives and employees
     ------------------
shall at all times give prompt, courteous and efficient service to End Users it
has contact with pursuant to its obligations under this Agreement, or otherwise
on behalf of Bell Atlantic.  Both parties shall follow all End User interface
procedures set forth in a Service Schedule and/or developed and agreed upon by
the parties.

3.4  Training Support.  Genuity shall specify the level of training required to
     ----------------
sell and support the Genuity Services.  Genuity shall make available, at its
expense (other than travel and lodging expenses for Bell Atlantic employees)
training support materials and training for the Genuity Services that is
substantially equivalent to the training Genuity provides to its internal sales
force (excluding Genuity-proprietary content such as strategic planning,
internal sales discussions, Genuity market focus, Genuity customer specific
information, and similar content) and is sufficient to qualify Bell Atlantic
employees to provide the necessary technical expertise to design where
applicable (on a pre-sale basis), sell and support the volume and type of
Genuity Services which Bell Atlantic has forecast.  This training shall be made
available initially for a reasonable number of Bell Atlantic sales personnel, as
mutually determined by the parties.  Genuity shall make subsequent training
available for new Genuity Services and significant enhancements to the services,
and periodically during the term of this Agreement (no more frequently than once
each calendar year) for a reasonable number of new sales personnel.  Additional
training required by Bell Atlantic shall be provided by Genuity at Bell
Atlantic's expense, at a price not to exceed Genuity's reasonable costs of
providing the training.  The parties shall develop a training support plan
within ninety (90) days of the effective date of this Agreement.

3.5  Marketing Support. Genuity shall reasonably assist Bell Atlantic in Bell
     -----------------
Atlantic's marketing and provision of the Genuity Services to End Users
identified by Bell Atlantic.  The parties shall develop procedures and
guidelines for such marketing support within ninety (90) days following the
Effective Date.  Such assistance shall include making sales support and
technical experts reasonably available for consultation with Bell Atlantic and
the End User.  At Bell Atlantic's request, Genuity shall provide qualified sales
and/or technical support individual(s) to accompany Bell Atlantic on sales calls
End Users. In such joint presentation to an End User, Bell Atlantic shall
determine whether the proposed service shall be identified as a co-branded
offering. Genuity's sales support and technical personnel who work on End User
accounts associated with Bell Atlantic marketing activities shall not
concurrently provide services pertaining to that End User to either Genuity's
internal sales channels or any other reseller of Genuity.  Any information about
the End User, to include the identification of the sales opportunity, that is
provided by Bell Atlantic, or that is developed by Genuity in its support of
Bell Atlantic's sales efforts, shall be Bell Atlantic Confidential Information.
In providing business and marketing support to Bell Atlantic pursuant to this
Section 3.5, Genuity shall not sell or attempt to sell the products or services
of any party other than Bell Atlantic, provided, however, that Genuity may,
                                       -----------------
while providing such support and in consultation with Bell Atlantic, make
recommendations to End Users regarding other Genuity Services available from
Bell Atlantic.

3.6  Availability of Services and Support.
     ------------------------------------

                                                                               4
<PAGE>

(a)  Genuity shall provide to Bell Atlantic the same type and quality of Genuity
Services (including, without limitation, Service Descriptions, service level
agreements and remedies, geographic availability, and support) as Genuity
provides to other resellers and to its own internal sales channel and retail
customers. Genuity shall modify the Genuity Services and add new Genuity
Services as reasonably necessary to keep the portfolio of Genuity Services
(including, without limitation, Service Descriptions, service level agreements
and remedies, capacity availability in the Territory, and support) available
under this Agreement competitive and current with comparable services available
from other suppliers. Genuity shall not reduce the geographic coverage of a
Genuity Service existing as of the date the parties executed this Agreement.
Subject to the foregoing, Genuity shall be the sole determiner of its services
portfolio and its market strategy, including the market segments upon which it
shall focus and the levels of investment it shall make in particular services or
market segments, or the geographic locations in which it will offer the Genuity
Services.

(b)  Genuity shall keep Bell Atlantic informed about new service offerings and
significant product enhancements, and shall offer any new services and service
enhancements to Bell Atlantic so that Bell Atlantic may market such new services
or enhancements to End Users on as timely a basis as Genuity's internal sales
channel or Genuity's other resellers or sales agents. In the event that Bell
Atlantic has information that one or more of the Genuity Services are not
competitive in the market, Bell Atlantic shall provide evidence thereof to
Genuity and Genuity shall review this information and meet with Bell Atlantic to
provide Genuity's response to Bell Atlantic's information.

(c)  Within ninety (90) days of the Effective Date, the parties shall develop a
benchmarking process to track prices and related terms for services comparable
to the Genuity Services for the purpose of administering this Section 3.6.

3.7  Availability of Competitive Terms and Prices For Individual Customer
     --------------------------------------------------------------------
Requests
--------

(a)  Bell Atlantic may request that Genuity provide reduced prices or discounts,
different terms, or changed Service Descriptions ("Custom Bids") for purposes of
responding to individual End User requests for proposals or negotiation with the
End User. When Bell Atlantic has quoted Genuity Services and the End User has
requested a Custom Bid, Bell Atlantic shall as soon as possible consult with
Genuity regarding such requests. Genuity agrees to give good faith consideration
to such requests, to offer such changes as Genuity determines it is willing to
make and to respond to Bell Atlantic within the timeframes of the individual
transaction which has generated such request. Bell Atlantic may obtain offers of
services comparable to, or as reasonable substitutes for, Genuity Services from
third parties. Where prices and/or other terms for such services are both
responsive to the particular customer request and more favorable to Bell
Atlantic than the prices and/or terms for Genuity Services, Bell Atlantic may
notify Genuity that it has received offers that include such favorable prices
and terms and request Genuity to meet such prices and terms. Genuity shall
respond within the timeframes of an individual sales transaction as requested by
Bell Atlantic. The parties agree to establish procedures under which such
requests shall be handled, no later than ninety (90) days after the Effective
Date, and to add such procedures as a schedule to this Agreement. Genuity shall
treat information concerning price reductions and other information requested as
Confidential Information of Bell Atlantic. Bell Atlantic shall treat Genuity's
response, including any information developed by Genuity and provided to Bell
Atlantic regarding pricing and other competitive information, as Confidential
Information of Genuity and shall not provide such information to any third party
other than in connection with providing a bid to the End User or as otherwise
permitted by this Agreement.

(b)  Genuity shall be obligated to provide Custom Bids to Bell Atlantic with
respect to a Genuity Service where Genuity customarily provides such Genuity
Service to other customers on a custom basis. In situations not covered by the
preceding sentence, Genuity

                                                                               5
<PAGE>

shall not be obligated to respond to Bell Atlantic requests for Custom Bids to
the extent they exceed twenty percent (20%) of the quotes requested by Bell
Atlantic for a particular Genuity Service in a calendar quarter.

3.8  Proposal Materials.  Unless otherwise agreed by Bell Atlantic, all sales
     ------------------
collateral, proposals, contracts and related proposal documents for Genuity
Services covered by this Agreement and marketed by Bell Atlantic shall be
prepared and presented by Bell Atlantic, using Bell Atlantic letterhead and
other indicia.  Genuity shall provide content that may be used without Genuity
identification, as requested by Bell Atlantic.  Bell Atlantic agrees to take all
reasonable steps necessary to protect Genuity's intellectual property rights in
such content, including reproducing all copyright notices, if any.  Bell
Atlantic further agrees that Genuity shall retain all rights in such content.
If the End User indicates interest in Genuity services that are outside the
scope of the Genuity Services, Genuity shall coordinate with Bell Atlantic
before making a proposal for such services.  Genuity may submit proposal
materials and customer contracts for such other services using Genuity
letterhead, forms and indicia.

3.9  Return of Materials.  Upon request from Bell Atlantic, Genuity shall return
     -------------------
or destroy all materials provided by Bell Atlantic related to any proposal
development or other marketing activity pertaining to an End User identified by
Bell Atlantic.  In such event, Bell Atlantic shall return to Genuity or destroy
all proposal development or marketing material Genuity has provided to Bell
Atlantic relating to such End User.

4.  OBLIGATION OF BOTH PARTIES

4.1  No Disparaging Conduct.  Neither party shall do anything that would tend to
     ----------------------
discredit, dishonor, reflect adversely upon, or in any manner injure the
reputation of the other party or any affiliate.  This provision shall not,
however, prevent either party from marketing competing services of either itself
or other entities.

4.2  Identification with a Party.  Representatives of a party shall not
     ---------------------------
represent themselves as employees of the other party in contacts with End Users
or others.

agreements shall contain terms and conditions that are at least as

                                                                               6
<PAGE>

protective of Genuity as the mandatory flowdown terms specified in the
applicable Service Schedule.

5.8  Order Forecasts, Bell Atlantic shall provide Genuity with calendar
     ---------------
quarterly forecasts no later than the first day of the calendar quarter.  The
forecast shall reflect anticipated demand for the Genuity Services for the next
eighteen (18) months by volume for each Genuity Service and shall reflect, if
the information is available, the anticipated geographic areas where the Genuity
Services shall be sold.  Genuity shall treat the forecasts as Bell Atlantic
Confidential Information. Within sixty (60) days following the Effective Date of
this Agreement, the parties shall develop mutually agreed upon detailed
forecasting requirements for each Genuity Service that shall be set forth as
supplements to the applicable Service Schedules. The parties agree to work
together to make the forecasting process a mutually beneficial business
arrangement that supports each party's planning.  Bell Atlantic shall make
reasonable efforts to provide Genuity with the most complete and accurate
forecast information possible for Genuity to effectively plan service
availability.  Reasonable efforts shall be made by Genuity to make the Genuity
Services available to meet Bell Atlantic's forecasts.

6.  TERM AND TERMINATION

6.1  Term.  This Agreement shall take effect on the date on which, pursuant to
     ----
their Agreement and Plan of Merger, Bell Atlantic Corporation and GTE
Corporation cause a Certificate of Merger to be executed, acknowledged, and
filed with the Secretary of State of New York as provided in New York
Corporation Law, Section 907 ("Effective Date"), and unless terminated earlier
as provided herein, shall continue for a period of five (5) years thereafter
(the "Initial Term").  The Agreement shall then renew for successive one (1)
year renewal terms ("Renewal Term") unless either party provides the other with
notice at least sixty (60) calendar days prior to the end of the Initial or
Renewal Term of its intent to allow this Agreement to expire at the end of the
current term.  Upon expiration of this Agreement, in the event a Service
Schedule or Schedules has or have a term ("Service Schedule Term") that
extend(s) beyond the Initial or Renewal Term, as applicable, the Term shall be
automatically extended and remain in effect until such time as all such Service
Schedule Terms have been completed.

6.2  Termination for Default.  Either party may terminate this Agreement, and/or
     -----------------------
one or more Service Schedule if the default applies to such Service Schedules,
without liability to the other party immediately by written notice in the event
the other party (i) materially breaches this Agreement and fails to cure such
breach within thirty (30) days following written notice thereof, provided,
however, that if such breach cannot reasonably be cured during that time, the
defaulting party must use reasonable commercial efforts to cure such breach as
soon as practicable but in any event within ninety (90) days, (ii) engages in
fraud, criminal conduct or willful misconduct in connection with the business
relationship of the parties, or (iii) becomes insolvent, becomes involved in any
liquidation or termination of its business, is adjudicated as bankrupt or
effects an assignment for the benefit of creditors.  In the event Bell Atlantic
elects to terminate this Agreement pursuant to this Section, Genuity shall
continue to provide the Genuity Services to any existing Bell Atlantic End Users
receiving Genuity Services under a valid End User contract with Bell Atlantic as
of the effective date of such termination provided however, that Genuity shall
have no obligation to provide services to any such End User beyond the then
current term of the End User's contract with Bell Atlantic.  The parties shall
negotiate in good faith with respect to any additional Genuity Services that
Bell Atlantic may wish to acquire after the effective date of such termination,
but Genuity shall have no obligation to agree to provide such services to Bell
Atlantic. In the event Genuity terminates this Agreement pursuant to this
Section, Bell Atlantic agrees to cooperate with Genuity and perform the same
obligations described in Section 6.3 below to effect the transition of all
outstanding End User agreements for the services to Genuity.  Bell Atlantic
shall provide its assistance at no charge to Genuity.

                                                                               7
<PAGE>

6.3  Early Termination by Bell Atlantic.  In the event a legislature, regulatory
     ----------------------------------
agency, court or other governmental entity, by act or omission, materially and
adversely changes the rights, obligations or risks of Bell Atlantic with respect
to the sale of the Genuity Services, then Bell Atlantic may terminate this
Agreement or any Service Schedule without liability by providing at least ninety
(90) days advance written notice thereof to Genuity.  In such event, to the
extent permitted by the End User, Bell Atlantic shall provide Genuity with
copies of all End User agreements for the affected Genuity Service(s) and other
End User information and shall cooperate to effect an orderly and seamless
transition to Genuity of all outstanding End User agreements for affected
Genuity Services (including the assignment to Genuity of such agreements).  Bell
Atlantic shall reimburse Genuity for reasonable out-of-pocket costs incurred
with respect to such transition.  Genuity shall not be required to assume an End
User agreement if it does not contain a mandatory flowdown provision or contains
other terms and conditions that are materially different from Genuity's standard
terms and conditions and if Genuity and Bell Atlantic are unable, despite
reasonable efforts to amend such  agreements to add such mandatory flowdown
terms.  Notwithstanding the foregoing, where Genuity has designated pursuant to
Section 1.1 a Genuity service provider that is a private carrier for the
provision of capacity services (e.g., private line and ATM), then Genuity's
obligations under this Section 6.3 with respect to the affected End User
agreements shall be limited to Genuity using commercially reasonable efforts to
arrange for another reseller of the Genuity Services to assume such End User
agreements, provided, however, that Genuity may itself assume some or all of
such End User agreements.

6.4  Effect of Expiration.  At Bell Atlantic's request, upon expiration, Genuity
     --------------------
shall (i) use commercially reasonable efforts in making an orderly and seamless
transition of End Users from the Genuity Services to other services that Bell
Atlantic may choose to offer such End Users; and (ii) continue providing the
Genuity Services to Bell Atlantic as necessary to complete the then-current term
of each End User contract that extends beyond such expiration or termination.

6.5  Use of Program Materials Upon Termination.  Except for any use that may be
     -----------------------------------------
necessary to perform its obligations under any existing End User agreements,
Bell Atlantic shall, upon termination or expiration of this Agreement,
immediately cease the use of all Genuity program materials and the Genuity marks
related to the affected Genuity service and Bell Atlantic shall cease to
represent itself as a Genuity reseller for the affected Genuity Service.  Bell
Atlantic shall return to Genuity all material previously provided by Genuity to
Bell Atlantic.

7.  PRICING; PAYMENT TERMS; MINIMUM ORDER

7.1    Purchase Price. The price for each of the Genuity Services is set forth
       --------------
in the applicable Service Schedule.  Some Genuity Services may include
installation fees, usage fees and telco circuit connection and cancellation
fees.  To the extent Genuity is unable to identify such fees in the Service
Schedule or at the time an order is placed, it shall provide Bell Atlantic with
a good faith estimate thereof and notify Bell Atlantic as soon as it becomes
aware of the amount of such fees.  Genuity shall pass through such fees to Bell
Atlantic at the cost and shall use commercially reasonable efforts to obtain the
lowest cost.  Such prices, including the above mentioned fees and costs,
constitute the totality of charges for which Genuity may bill Bell Atlantic in
connection with the purchase of the Genuity Services and performance of its
obligations under this Agreement; no other charges (except for taxes as
permitted below) shall appear on any invoice to Bell Atlantic unless otherwise
agreed upon in writing by the parties.

7.2    Minimum Order.  Any minimum purchase commitment applicable to individual
       -------------
Genuity Services shall be set forth in the applicable Service Schedule.

7.3    Volume Purchase Commitment. In consideration of the performance
       ---------------------------
commitments

                                                                               8
<PAGE>

and other promises of Genuity as set out in this Agreement, Bell Atlantic agrees
to purchase the Genuity Services in the dollar volumes as set out in Attachment
1 (the "Purchase Commitment") or pay to Genuity the amounts described therein in
the event it fails to satisfy the Purchase Commitment.

7.4  Most Favored Customer.
     ---------------------

(a)  The Multiple Services Discount (as defined in the pricing attachments
hereto) offered to Bell Atlantic under this Agreement shall be at least as
favorable to Bell Atlantic as any Multiple Services Discount, or any similar
discount, offered, to any other non-government customer of the Genuity Services
who has made a comparable or lower purchase or volume commitment for the Genuity
Services under similar financial terms and conditions.

(b)  The individual Genuity Service Baseline Pricing and Volume Discounts (as
such terms are defined in the pricing attachments hereto) offered to Bell
Atlantic for each of the Genuity Services (other than Genuity Services that are
customized for Bell Atlantic pursuant to Section 3.7) available under this
Agreement will be at least as favorable to Bell Atlantic as the pricing and/or
discounts offered to any other non-government customer of the Genuity Services.

(c)  Exclusions:  The foregoing subsection (b) shall not apply to:

(1)  Discounts offered for Genuity Service(s) (or service components) to a
customer that are offset by lesser discounts on other Genuity Service(s) (or
service components) such that, given such customer's purchase commitments for
such Genuity Services, Bell Atlantic's discounts in aggregate are more
favorable;

(2)  Discounts are offered in good faith in exchange for corresponding (and
quantifiable, if practicable) value from a customer (e.g., in settlement of a
claim, in exchange for marketing or advertising, in consideration of customer-
unique cost reductions, etc.); provided, however, that in the event such
consideration could reasonably apply to Bell Atlantic and Genuity, then Genuity
shall offer such discounts along with the corresponding terms and conditions
reasonably and economically required to offer such pricing, in accordance with
section (d), below;

(4)  Discounts offered by Genuity on an exceptional basis resulting in pricing
with no margin for the purpose of securing strategic accounts; or

(5)  Discounts or pricing offered for beta tests or pilot programs that are
significantly limited in time and scope, in error, for charitable or promotional
purposes; or for any de minimus contracts (less than $24,000 per year in
aggregate per customer or affiliate).

(d)  Process. Genuity will give Bell Atlantic written notice (in accordance with
this Agreement) of any more favorable discounts and/or pricing offered to
another buyer pursuant to sections (a) or (b) above, within thirty (30) days of
execution of a service agreement between Genuity and such buyer. Within thirty
(30) days of receipt of such notice from Genuity, Bell Atlantic shall provide
Genuity with written notice in accordance with this Agreement of whether it
accepts such prices. If Bell Atlantic accepts such prices, this Agreement shall
be amended accordingly by a writing that is signed by the parties, and such
prices shall be deemed to apply as of the date the same were first offered to
such buyer. If a credit is due Bell Atlantic as a result of the application of
such prices, then Genuity shall either apply the resulting credit to Bell
Atlantic's account on the next invoice sent by Genuity to Bell Atlantic, or
refund the amount to Bell Atlantic, at Bell Atlantic's election.

7.5  Payment Terms.  Payments by Bell Atlantic in consideration of provision of
     -------------
Genuity Services by Genuity in accordance with this Agreement are due in United
States dollars in the United States net thirty (30) calendar days from receipt
of a valid and complete invoice.  In the event Genuity has not received payment
from Bell Atlantic within forty-five (45) days from the date of issuance of the
invoice by Genuity, and Bell Atlantic has not disputed the

                                                                               9
<PAGE>

invoice pursuant to the terms of Section 7.7, Genuity may, without limiting its
remedies at law or equity for any default, upon thirty (30) days written notice
to Bell Atlantic, suspend service to the End User for the affected service, if
Bell Atlantic has not within this period provided payment; provided, however,
that Genuity shall give Bell Atlantic written notice at least fifteen (15) days
in advance of taking such action which shall identify the End Users to whom
Genuity proposes to suspend service.

7.6  Interest on Overdue Amounts.  Genuity may charge Bell Atlantic interest at
     ---------------------------
the lower of 1.5% per month or the highest monthly rate permitted by law on all
invoiced amounts that are not in dispute, as provided in Section 7.7, below, for
which payment has not been received by the due date of such invoice.

7.7  Disputed Invoices.  In the event Bell Atlantic disputes an invoice issued
     -----------------
by Genuity for services performed under this Agreement, Bell Atlantic may, no
later than the due date of the invoice, notify Genuity in writing of such
dispute.  Such notice shall identify and describe in detail the basis for such
dispute.  Within thirty (30) days of the receipt of such notice by Genuity,
Genuity shall either correct the invoice, resolve the dispute, or respond in
writing to Bell Atlantic providing specific reasons why the invoice is correct.
If, within forty-five (45) days of the date of Genuity's response, the dispute
is not resolved, Bell Atlantic and Genuity shall each designate an executive to
meet and negotiate in good faith to resolve the dispute.  Bell Atlantic shall
pay any undisputed amount within the time frame noted in section 7.5, above, and
may withhold disputed amounts pending resolution of the dispute.  Within thirty
(30) days following the resolution of a dispute over an invoice, the party owing
an amount shall pay or credit the other the amount due.  Failure to raise a
dispute over an invoice in accordance with the procedures of this section shall
not prevent or prejudice Bell Atlantic in subsequently raising the matter.

7.8  Taxes and Duties.  Bell Atlantic shall be responsible for the payment of
     ----------------
any and all sales, value added, withholding or other taxes, duties, levies, fees
and other charges that are or may be imposed by any governmental entity based on
Bell Atlantic's sale of the Genuity Services to End Users.

8.  TRADEMARKS, TRADENAMES; PROPRIETARY RIGHTS

8.1  Co-Branded Genuity Services.  The Genuity Services and related customer
     ---------------------------
support services may be co-branded (e.g., "Bell Atlantic Web Hosting powered by
Genuity," etc.).  The form and content of such co-branding is set forth in the
Service Schedules.  Bell Atlantic may brand resold Genuity Services otherwise as
determined by Bell Atlantic, if Bell Atlantic makes no use of a Genuity name,
servicemark or trademark in association with the service.  Any co-branding shall
be in accordance with applicable federal law and Section 2.4 of this Agreement.

8.2  Trademark License. (i) Each party hereby grants to the other during the
     -----------------
Agreement Term a limited, nontransferable, and nonexclusive license, without the
right to grant sublicenses to use such party's Program Marks (as set out in the
Trademark Schedule or otherwise provided in writing) solely in connection with
the production and dissemination of co-branded marketing materials in the
Territory for the Genuity Services and in connection with co-branded customer
care materials for the Genuity Services to be performed by Genuity hereunder,
subject to the terms and conditions of this Agreement, to include compliance
with applicable federal law and Section 2.4 of this Agreement. (ii) Any and all
such materials using a party's Program Marks shall be developed in consultation
with that party, and shall not be publicly disseminated without the party's
prior written approval as to their form.  If a party at any time finds any
materials using its Program Marks to be deficient in quality or finds any
materials being marketed in a misleading or deceptive manner or otherwise in
violation of this Agreement, then it must notify the other in writing of such
deficiency, and the other party shall eliminate such deficiency within thirty
(30) days after receiving written notice.  A party shall have the right to
publish additional conditions and quality standards,

                                                                              10

from time to time, as is necessary to protect its Program Marks, provided such
conditions and standards are imposed on other use of the same marks by that
party or any of its Affiliates. A party shall not, directly or indirectly,
license or attempt to license, whether orally or in writing, any other person to
use any of the other party's Program Marks, and, shall make no assignment of any
right to use the Program Marks. Any attempt to assign any right to use Program
Marks other than as contemplated hereby as well as any attempt to license
another person or entity to use the Program Marks shall result in immediate
cancellation of the license granted herein. A party shall not have any right,
title, or interest in and to the other's Program Marks, or in the registrations
or applications for registration thereof, except only the right to use the
Program Marks as specifically authorized by this Agreement. Each party
acknowledges that its use of the other's Program Marks shall not create in its
favor any right, title, or interest therein. Neither party shall use any
trademark, service mark, corporate name, business name, trade name or domain
name identical with or confusingly similar to the other party's Program marks,
except for the Program Marks and then only as expressly permitted by this
Agreement. Each party agrees that it shall never directly or indirectly
challenge, contest or call into question or raise any questions concerning the
validity or ownership of the other party's Program marks or any registration or
application for registration for the Program Marks of the other party. Neither
party shall use any of the other's Program Marks except in the graphic format
set forth in Schedule A-2, or as otherwise provided for herein. If a party
decides in its sole discretion to modify or discontinue the use of any of its
Program Marks, the other party shall refrain from using the unmodified or
discontinued marks, destroy all designs, stationery, promotional materials,
advertising or other materials of every kind using any of the unmodified or
discontinued marks, and to commence using the modified or substituted marks in
accordance with this Agreement as if such marks had been identified herein,
provided that the party so modifying or discontinuing its Program Marks shall
promptly reimburse the other for any and all costs and expenses it incurs in
connection with the reprinting of new documentation and materials for use in
connection with such Program Marks and such other costs as it shall reasonably
incur.

8.3  Ownership of Work Product. Subject to pre-existing rights as to elements
     -------------------------
incorporated in the co-branded marketing and customer care materials ("Work
Product"), each party shall have and retain all ownership rights (including,
without limitation, ownership of any copyrights) in the work product that it
creates, and prepares, and all such work product shall remain the exclusive
property of that party.  Each party's trade name(s), trademark(s), logo(s) and
icon(s) shall remain its exclusive property, notwithstanding the fact that its
trade name(s), trademark(s), logo(s) and icon(s) have been included in a work
product prepared by the other party.  Each party hereby grants to the other
until the effective date of termination of this Agreement a limited,
nontransferable, and nonexclusive license to use its work product in the
Territory solely as necessary to perform such party's obligations hereunder.

9.  CONFIDENTIALITY

9.1  Nondisclosure and Nonuse Obligations. Each party shall not disclose to
     ------------------------------------
third parties all information and know-how in any form, transmitted to the other
that the disclosing party has identified, by letter or other written notice, as
being proprietary or confidential ("Confidential Information"), and shall make
no use of such information and know-how except under the terms and during the
term of this Agreement.  Each party shall treat as Confidential Information of
the other party information regarding the other party's pricing, marketing and
sales strategies, and internal operations procedures as proprietary and
confidential, regardless of whether such information has been identified
proprietary or confidential at the time of disclosure.  Neither party shall have
an obligation pursuant to the foregoing to protect that portion of such
information that (i) it rightfully received from another party, without
restriction on use or disclosure prior to its receipt from the disclosing party;
(ii) the disclosing party has disclosed to a third party without any
restrictions on use or disclosure; (iii) enters the public domain (i.e.

                                                                              11

without any restrictions on use or disclosure) by some action other than breach
of this Agreement by the receiving party; (iv) is independently developed by or
for the receiving party; or (v) is disclosed pursuant to a valid subpoena or
other government order. Each party shall safeguard proprietary or confidential
information disclosed by the other using the same degree of care it uses to
safeguard its own proprietary and confidential information but, in no event,
shall use less than a reasonable degree of care. Each party's obligation under
this paragraph shall extend for a period of three (3) years following
termination or expiration of this Agreement.

9.2   End User Information.  The parties agree to treat End User information, to
      --------------------
include proposals, pricing and type of services provided, as Confidential
Information under the terms of the preceding subsection.  In addition, the
parties agree that, as between them, the End User information of a customer that
is identified and brought into the Genuity - Bell Atlantic relationship as a
customer or potential customer, shall be the Confidential Information of the
party that identified and brought the End User to the relationship. If the
parties assist each other in the marketing of the Genuity Services, the End User
information related to that marketing shall be the confidential information of
the party that has the primary relationship with the End User.  A party that
receives End User information of the other party shall restrict its use of that
information solely to the transactions relating to the Genuity Services, and
shall not disclose any such End User information to other parts of the party's
organization, to include any other sales channel.

10.  INDEMNIFICATION.

10.1  Infringement. Genuity shall defend and indemnify Bell Atlantic and hold
      ------------
Bell Atlantic harmless from any damages, costs and attorneys fees finally
awarded against Bell Atlantic and its End Users based upon a claim that Genuity
Services infringe any U.S. patent, copyright, trademark, trade secret or other
intellectual property right provided that Bell Atlantic promptly notifies
Genuity in writing of such claim and cooperates with Genuity by providing
Genuity with the opportunity, full authority, and assistance (at Genuity's
expense) to defend or settle the claim.  Should any Genuity Service become, or
likely to become, in Genuity's opinion, the subject of a claim, Genuity may at
its option and expense: (i) replace or modify the Services so that that
infringement does not exist; (ii) procure for Bell Atlantic and its End Users
the right to continue to use the infringing Genuity Services; or, if (i) and
(ii) are not commercially reasonable, (iii) cease providing the infringing
Genuity Services and refund to Bell Atlantic any payments made for the
terminated Genuity Service for the period after the termination date.  This
section states the entire liability of Genuity with respect to infringement of
any intellectual property rights by Genuity and its suppliers and Genuity and
its suppliers shall have no additional liability with respect to any alleged or
proven infringement. Genuity shall have no liability for and Bell Atlantic shall
indemnify and hold Genuity and its suppliers harmless from any and all claims,
damages, costs and attorneys fees Genuity incurs from any claim arising solely
from (a) the combination, by Bell Atlantic or its End Users, of Genuity Services
with other products or services not provided by Genuity that are not authorized
by Genuity  or are not reasonably intended to be used in combination with the
Genuity Services, or (b) any alteration or modification of Genuity Services that
were not made or authorized by Genuity or (c) the use of a Genuity Service by
either Bell Atlantic or its End Users in a manner for which it was neither
intended or designed.   The parties disclaim the implied warranty of non-
infringement, relying instead on the terms of this Section.

10.2  General Indemnity.  Genuity and Bell Atlantic shall each indemnify, defend
      -----------------
and hold the other party and its affiliates, and their respective agents,
representatives, employees, directors, officers and assigns harmless against any
losses, damages, liabilities, claims or demands (including all costs, expenses
and attorneys' fees on account thereof or in connection with any investigation
or preparation related thereto or the enforcement of the indemnification
provisions of this Agreement) that may be made as a result of claims made: (i)
by anyone for bodily injuries (including death) to persons or damage to or theft
of tangible or

                                                                              12
<PAGE>

intangible property resulting from the indemnifying party's or its agents'
intentional and willful misconduct or negligent acts or omissions or those of
persons furnished by such party while performing work hereunder pursuant to this
Agreement or in connection with materials furnished by such party pursuant to
this Agreement excluding any claims based on lost data or information unless
such claims are based on intentional and willful misconduct; (ii) by persons
furnished by the indemnifying party or any contractors based on employment
contract, or federal, state or local laws prohibiting discrimination in
employment; (iii) by persons furnished by the indemnifying party or any
contractors under worker's compensation or similar acts; or (iv) resulting from
or in connection with the indemnifying party's or its agents' breach of any
applicable law, statute, order, decree, or regulation in performance of its
obligations hereunder. In addition, Bell Atlantic shall indemnify, defend and
hold harmless Genuity and its affiliates, and their respective agents,
representatives, employees, directors officers and assigns harmless against any
losses, damages, liabilities, claims or demands (including all costs, expenses
and attorneys' fees on account thereof or in connection with any investigation
or preparation related thereto or the enforcement of this indemnification
provision) that may be made by any third party for claims arising from Bell
Atlantic or Bell Atlantic's End Users' use of the Genuity Services and that are
not (i) otherwise subject to indemnification under this Agreement or a Service
Schedule, or (ii) proximately caused by the negligent acts or omissions or other
willful misconduct of Genuity or its affiliates, or their respective agents,
representatives, employees, directors officers or assigns. The indemnified party
shall provide written notice to the other party of any written claims or demands
against it for which the other party is responsible hereunder and shall be
entitled, at its option, to assume the defense or settlement of any such claim.

<PAGE>

14.2 Entire Agreement. This Agreement constitutes the entire agreement between
     ----------------
the parties with respect to the subject matter hereof and supersedes all prior
and contemporaneous communications, representations and agreements. The recitals
in this Agreement are illustrative only and shall not be binding on the parties.
This Agreement shall not be modified except by a written agreement dated
subsequent to the date this Agreement is executed by both parties, and signed on
behalf of the Bell Atlantic and Genuity by their respective duly authorized
agent. The provision of any Genuity Service to Bell Atlantic that was, prior to
the Effective Date of this Agreement, provided under another agreement, shall be
provided pursuant to this Agreement after the Effective Date. If the prices,
terms or conditions applicable to such Genuity Service are more favorable to the
End User under the prior agreement, the more favorable prices, terms or
conditions shall apply for that End User.

14.3 Severability. If any provision of this Agreement is declared or found to
     ------------
be illegal, unenforceable or void, then it shall be amended to the extent
necessary to make it legal and enforceable while preserving its intent; the
unenforceability of any provision of this Agreement shall not impair the
enforceability of any other provision of this Agreement.

14.4 No Waiver. No waiver of any breach of any provisions of this Agreement
     ---------
shall constitute a waiver of any prior, concurrent or subsequent breach of the
same or any other provisions hereof, and no waiver shall be effective unless
made in writing and signed by an authorized representative.

14.5 Nonassignability and Binding Effect. (i) Neither party shall assign any
     -----------------------------------
right or interest under this Agreement, except for monies due or to become due,
nor delegate any work or other obligation to be performed or owed under this
Agreement to any third party without the prior written consent of the other
party, provided, however, that the merger or consolidation of one party into, or
the sale of all or substantially all of the assets of such party to, a third
party shall not be deemed to be an assignment. Any attempted assignment or
delegation in contravention of the above shall be void and ineffective.  Subject
to the foregoing, this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their permitted successors and assigns.
Notwithstanding the above, each party shall have the right to assign this
agreement and to assign its rights and delegate its duties under this agreement,
either in whole or in part (an "assignment"), at any time and without the other
party's consent, to any wholly-owned subsidiary or affiliate of the assignor.
The assignor shall give the non-assigning party written notice of any
assignment.  The assignment shall neither affect nor diminish any rights or
duties that either party may then or thereafter have as to Genuity Services
ordered by Bell Atlantic prior to the effective date of the assignment.  (ii)
Any assignment of monies by the assignor shall be void and ineffective to the
extent that (i) the assignor has not given the non-assigning party at least
sixty (60) days prior written notice of such assignment and (ii) such assignment
attempts to impose upon the non-assigning party obligations to the assignee
additional to payments of such monies or to preclude the non-assigning party
from dealing solely with the other party in all matters pertaining to the
Agreement.

14.6 Force Majeure. Neither party shall be in default of any obligation under
     -------------
this Agreement or any Service Schedule nor liable for any delay or failure in
performance which results directly or indirectly from Acts of God, casualty,
acts of civil or military authorities, civil disturbances, war, strikes or other
labor-related disputes, fires, disruption in transportation, flood, lock out,
epidemic, destruction or shut-down of facilities, railroad disaster, cable cut,
shortage or curtailment, or other causes beyond the party's reasonable control.

14.7 Regulatory Compliance. This Agreement is subject at all times to any
     ---------------------
statute, order, rule, or regulation or any state or federal regulatory agency
having competent jurisdiction over one or both of the parties hereto or the
services provided hereby.  The parties agree to cooperate with each other and
with any applicable regulatory agency so that any and all

                                                                              15
<PAGE>

necessary approvals may be obtained. During the term of this Agreement, the
parties agree to continue to cooperate with each other in any review of this
Agreement by a regulatory agency so that the benefits of this Agreement may be
achieved. Notwithstanding the Effective Date and term of this Agreement as
stated elsewhere, to the extent that any statute, order, rule or regulation or
any regulatory agency having competent jurisdiction over one or both parties to
this Agreement, shall require that this Agreement or subsequent amendment be
filed with or approved by such regulatory agency before the Agreement or
amendment may be effective, this Agreement or amendment shall not be effective
in such state until the first business day after such approval or filing shall
have occurred.

14.8   Continuing Obligations. Notwithstanding termination or expiration of this
       ----------------------
Agreement or any Service Schedule hereunder, Bell Atlantic's obligation to pay
for Genuity Services provided hereunder shall continue.  Any obligations,
duties, or rights that may, by their nature, extend beyond the expiration or
termination of this Agreement or any particular Service Schedule, shall survive
any such expiration or termination.  Nothing in this section shall affect either
party's rights or remedies at law or in equity in the event of a breach by the
other party.

14.9   Governing Law. This Agreement shall be governed by the laws of the
       -------------
Commonwealth of Massachusetts without regard to its conflicts of laws
principles.

14.10. Compliance with Laws.  The parties shall comply with all applicable
       --------------------
laws, statutes, ordinances, directives, rules, regulations, orders and decrees
of any court or regulatory authority of competent jurisdiction in performing
this Agreement. If Bell Atlantic requires Genuity to temporarily adjust its
business as set forth in this Paragraph, Bell Atlantic shall provide Genuity
with 180 days prior written notice of the date on which Bell Atlantic intends to
exercise its option to convert its B Shares of Genuity stock ("Bell Atlantic
Notice"). In the Bell Atlantic Notice, Bell Atlantic may, at its discretion,
designate certain States in which it does not expect to have legal authority
under applicable federal law ("Bell Atlantic Designated States"), to operate
Genuity at the time of the Bell Atlantic conversion. Upon receipt of the Bell
Atlantic Notice, Genuity shall temporarily adjust its business in the Bell
Atlantic Designated States in such a manner, as Genuity determines in its sole
discretion, as will allow Genuity to operate in compliance with applicable
federal law in such States on or before the conversion date set forth in the
Bell Atlantic Notice. In no event shall (1) the Bell Atlantic Designated States
account for greater than 3 percent of Genuity's total revenue, as measured by
comparing the revenue arising out of Genuity business in the Bell Atlantic
Designated States to Genuity's revenue for its overall operations for the prior
12 months before the date of the Bell Atlantic Notice and/or (2) the
adjustment of Genuity's operations result in the loss to Genuity of overall
revenue of more than 3% of its revenue for the prior 12 months before the date
of the Bell Atlantic notice. Bell Atlantic agrees to pay an amount necessary to
make Genuity financially whole as a result of Genuity's modifications to its
business under this Paragraph. Such amount shall not be greater than 3 percent
of Genuity's total revenue, as described above.

14.11. Additional Remedies. The rights and remedies set forth in this Agreement,
       -------------------
unless otherwise stated in this Agreement, are in addition to and not in
substitution of all rights and remedies available to the parties at law, in
equity, or otherwise.

arbitration or lawsuit.  The parties agree to pursue resolution under this
subsection for a minimum of 60 days following the first written notice
requesting initiation of these dispute resolution procedures before pursing
arbitration as set forth in subsection (b), below.  The foregoing procedure
shall not apply to claims or disputes relating to confidential information,
other intellectual property, or indemnity rights or obligations.

(b)  If the parties cannot resolve the dispute in accordance with subsection
(a), above, either party shall have the right to cause the parties to enter into
binding arbitration in accordance with the rules of the American Arbitration
Association then in effect. The place of arbitration shall be conducted in the

     accessed by Bell Atlantic shall include, but not be limited to, the
     following product specific information (as available): detailed product
     descriptions, product advisories, product white papers, technical
     documentation (i.e. system administration and configuration manuals,
     standard operating procedures, and all information relative to product
     hardware/software revisions).

     time jeopardy/reason missed notification and estimated time to resolve.

(vi)      Upon request, Genuity will order the LEC/CAP circuit for Bell
     Atlantic's customer on behalf of Bell Atlantic. Genuity will use
     commercially reasonable efforts to obtain discounts commensurate with

     priced as "pass-through", Genuity will pass through actual charges without
     mark-up.

(vii)     Upon Bell Atlantic End User order completion, Genuity will provide
     Bell Atlantic the same End User raw data utilized by Genuity in the

     of Genuity's receipt of the order, the order will be presumed accepted by
     Bell Atlantic unless Genuity informs Bell Atlantic to the contrary.

(ii)      Genuity will provide time frame commitment for cancellation of service
     after notification by Bell Atlantic.

(iii)     Genuity will provide current order status log by 5:00 AM Eastern Time

     unable to identify, isolate or correct the trouble. Such trouble may be
     complex and require technical expertise and broad product and service
     knowledge. In the event Genuity receives the trouble report from Bell
     Atlantic's End User, or from Genuity's internal electronic monitoring
     systems, Genuity shall agree to notify Bell Atlantic via phone and/or
     E-mail with all pertinent information. Both Parties will mutually agree

fee shall not apply to those instances where service was terminated due to
Genuity's failure to timely cure a material breach of its obligations, as
established in this Service Schedule.

Section IV: The following additional terms apply to VPN Advantage, Managed VPN,
----------
SitePatrol, and Security Advantage Services (and bundles containing such
services as a component):

1.   Approved Internet Connectivity.  Bell Atlantic agrees to use only such
     ------------------------------
Internet connection services as are compatible with the Services, as determined
by Genuity in advance.

2.   Service Cancellation: Bell Atlantic may cancel a Service connection at any
     --------------------
time by providing 60 days prior written notice via email to the designated
cancellation point of contact. Bell Atlantic agrees to pay all Service fees
accrued as of the effective cancellation date and an early cancellation fee
equal to: for one-year Service quotations, 25% of the other monthly fees due for
the canceled portion of the Service period, or for multi-year Service
quotations, 25% of the other monthly fees due either (i) until the end of the
2nd year of the quotation's Service period, or (ii) for one (1) year following
the effective cancellation date, whichever is greater.  The early cancellation
fee shall not apply to those instances where service was terminated due to
Genuity's failure to timely cure a material breach of its obligations, as
established in this Service Schedule.

3.   Deployment Contingencies.  Bell Atlantic acknowledges that deployment of
     ------------------------
encryption technology internationally may be subject to restrictions.  Genuity
will endeavor to obtain the necessary approvals for each international site
ordered.  Bell Atlantic agrees to cooperate with Genuity as may be reasonably
necessary to satisfy the required approvals.  In some cases, approval may
require the passing of title of certain customer premises equipment to the End
User.  Bell Atlantic agrees to secure the reasonable cooperation of End User to
assist in obtaining the requisite approvals.  Genuity's acceptance of an order
for Service, and Genuity's  obligation to provide Service, in any

                                                                               8
<PAGE>

given non-U.S. location is expressly conditioned on Genuity's ability to obtain
the regulatory, legal, vendor, and import and export approvals (including those
required for encryption technology) as Genuity deems necessary and under such
terms and conditions as Genuity deems adequate, in Genuity's sole discretion. In
the event that Genuity is unable to obtain such approvals for a given location,
Genuity may decline to accept or void the order quotation for Services at that
location without penalty or obligation. For applicable international Services,
this section shall supercede any acceptance criteria stated elsewhere in the
agreement.

4.   Security Policy.  End Users remain responsible for their network security
     ---------------
policy and security violation response procedures. VPN Service enhances End
Users' ability to create and secure a virtual private network and impede
unauthorized access to the End User's network and data transmitted using the VPN
service. Bell Atlantic acknowledges that VPN Service does not by itself
guarantee network security or prevent security incidents, that neither Genuity
nor its suppliers is responsible for unauthorized access to the End User's
facilities or for damages arising out of unauthorized access, and that it is the
End User's responsibility to design a comprehensive security program in
conjunction with any other service providers or professionals chosen by End
User.

5.   Restrictions on system access.  Genuity configures and remotely manages the
     -----------------------------
software for all systems Genuity installs on an end user's premises in
conjunction with VPN service (e.g., The VPN gateway device). Bell Atlantic shall
include terms in its agreements with end users which allow Genuity (or
designated representative) to access End Users' premises for the purpose of
installing and maintaining such equipment. End User may access the configuration
of such systems only when authorized by Genuity; therefore, neither Bell
Atlantic nor end user will need or receive a software license. Bell Atlantic
agrees to abide by, and ensure that end users abide by, the license terms to the
VPN client software. Bell Atlantic agrees not to, nor permit End Users to,
remove, obliterate or cover any marks, logos, or notices included with the
equipment Genuity installs on End Users' premises.

6.   Return of Equipment and Software.  Upon termination or expiration of the
     --------------------------------
Service Period applicable to any End User (unless extended by the parties), Bell
Atlantic agrees to return or cause End User to either return  to Genuity or
dispose of all hardware and software which Genuity has provided to in connection
with the VPN Service in accordance with the following:

     6. 1.  Genuity-Owned Equipment and Software.  Bell Atlantic agrees to
            ------------------------------------
     return to Genuity all Genuity-owned hardware and software which Genuity has
     provided to Bell Atlantic and/or End User in connection with the VPN
     Service. If such hardware and software are not returned to Genuity within
     sixty (60) days following such termination or expiration, Bell Atlantic and
     End User will permit Genuity to remove such hardware and software from End
     User's premises upon reasonable notice during normal business hours, at
     Bell Atlantic's or End Users cost and expense. Bell Atlantic will also be
     responsible for all applicable late return fees, as stated in the Service
     Description.

     6.2    Genuity-Provided Equipment.  In certain cases, Genuity may pass
            --------------------------
     title of equipment to End User for a given site, as specified in the
     service order (or otherwise agreed to in writing between the parties). In
     the event that title to equipment is passed to End User, then, at the end
     of the applicable service period, End Users shall agree to either: (a)
     transfer title to the equipment to Genuity or a designated agent in
     exchange for its remaining salvage value; or (b) to destroy the equipment,
     and certify such destruction, in accordance with U.S. and local laws.

     6.3    Genuity-Provided Software.  Regardless of the origin or ownership of
            -------------------------
     the hardware End Users shall agree that, at the end of the applicable
     Service Period End User shall, at Genuity's option, either: (a) certify
     that End User has returned and/or destroyed any software which Genuity has
     provided to End User (or End User's foreign affiliate) in connection with
     the VPN Service including media containing copies thereof (e.g. CD ROM); or
     (b) permit Genuity to remove and/or delete such software, copies and media.

7.   Export Restrictions. The customer premises equipment and software (e.g. the
     -------------------
VPN Gateway Device) installed on the customer premises are authorized by the
U.S. government (and other applicable regulatory authorities) for export only

                                                                               9
<PAGE>

to the country/location authorized in the applicable Service Order or otherwise
authorized in writing by Genuity.  They may not be resold, diverted,
transferred, transshipped, or otherwise be disposed of in any other country,
either in their original form or after being incorporated through an
intermediate process into other end items, without the prior written approval of
the U.S. Department of Commerce and Genuity.  Bell Atlantic acknowledges that
the VPN client software contains encryption technology subject to export
control, and agree to abide by, and ensure that end users abide by, laws and
regulations applicable to import and export of the VPN client software.

8.   Warranties Regarding Third Party Equipment.  In the event that Genuity
     ------------------------------------------
transfers title to equipment to Bell Atlantic or End User, Genuity will endeavor
to pass through such representations and warranties provided by the manufacturer
of any equipment purchased from Genuity hereunder.  Bell Atlantic understands
and agrees that the sole and exclusive recourse for any claims or damages
relating to the third party equipment shall be to the manufacturer of such
equipment, and not to Genuity.  Except as expressly provided elsewhere in the
Agreement, Genuity is providing the equipment AS IS, AND GENUITY DISCLAIMS ALL
WARRANTIES OR REPRESENTATIONS, BOTH EXPRESS AND IMPLIED, INCLUDING BUT NOT
LIMITED TO THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  UNDER NO CIRCUMSTANCES SHALL GENUITY BE LIABLE FOR ANY DAMAGES THAT
MAY RESULT FROM THE USE OF OR INABILITY TO USE THE EQUIPMENT.

Section V:  The following additional terms apply to DiaLinx Services, including
---------
DiaLinx VISP Services (and bundles containing such services as a component):

1.   End User Responsibility:  Bell Atlantic agrees to be responsible for all
     -----------------------
billing and collection from  individual users and that Bell Atlantic will pay
Genuity on a timely basis, regardless of whether Bell Atlantic collects payment
fromusers.  Bell Atlantic agrees to be responsible for all communications to and
business relations withusers.  Unless Bell Atlantic has purchased optional help
desk services from Genuity, Bell Atlantic shall be responsible for providing all
technical support related to DiaLinx Service access for users, including but not
limited to responding to inquiries and questions, hot-line support, problem
resolution, providing system configuration, installation and support, as
applicable and other such services and shall maintain an organization which is
highly trained and qualified to provide such support.  Bell Atlantic is
responsible for authenticating and authorizing access by Bell Atlantic's users
to the DiaLinx Service.  Unless Bell Atlantic has purchased optional RADIUS
hosting services from Genuity, Bell Atlantic shall install, operate, and
maintain a dedicated RADIUS server meeting the RADIUS specifications published
in Internet RFC 2138 and 2139 and all published derivative RFC's.  Genuity's
RADIUS server will prompt each end user for the end user's identification and
password, and poll Bell Atlantic's RADIUS server for access information.  Unless
otherwise additional realms are purchased, Genuity will support up to a maximum
of five (5) authentication realms (e.g. companyname.com) per End User.

2.   Service Cancellation: Bell Atlantic may cancel a Service connection at any
     --------------------
time by providing 60 days prior written notice via email to the designated
cancellation point of contact.

3.   Equipment and Telephone Service.  Bell Atlantic is solely responsible for
     -------------------------------
obtaining and providing the telephone services and user modems necessary to
access DiaLinx Service.  In no event will Genuity be responsible for end user
telephone charges.

4.   Network Access Availability.  ACCESS TO THE DIALINX NETWORK CANNOT BE
     ---------------------------
GUARANTEED TO BELL ATLANTIC OR BELL ATLANTIC'S END USERS.  END USERS MAY BE
UNABLE TO ACCESS THE DIALINX SERVICE AT ANY GIVEN TIME, AND DISCONNECTIONS MAY
OCCUR FROM TIME TO TIME.  BELL ATLANTIC AGREES THAT GENUITY WILL NOT BE LIABLE
FOR ANY DAMAGES THAT BELL ATLANTIC OR BELL ATLANTIC'S END USERS MAY INCUR
ARISING OUT OF THE USE OR INABILITY TO USE THE DIALINX SERVICE. THIS DISCLAIMER
IS IN ADDITION TO, NOT INSTEAD OF, THE DISCLAIMER,  LIMITATION OF LIABILITY AND
LIMITATION OF DAMAGES CONTAINED IN THE AGREEMENT.

                                                                              10
<PAGE>

5.   Regulatory Changes.  Genuity shall flow through to Bell Atlantic any local
     ------------------
exchange carrier (LEC) price changes (a) that are attributable to changes in
Federal or state regulation, or (b) for Federally regulated services, that are
treated as exogenous regulatory cost changes by the Federal Communications
Commission (the "FCC") under its price caps regulations as defined in the FCC
Rules, 47 C.F.R. Section 61.45. For purposes of this paragraph, price changes
attributable to changes in regulation include, but are not necessarily limited
to, price changes reflecting total or partial elimination of any enhanced
services provider exemption from payment of interexchange access charges or any
regulatory decision which results in application of multiple Subscriber Line
Charges to ISDN Primary Rate interface circuits or channelized T1 circuits.

6.   Local Access Numbers. Genuity expects the DiaLinx network to change over
     --------------------
time in order to meet the needs of customers. Genuity reserves the right to add
to, delete or change the dial-in access numbers associated with a specified
service category from time to time. Bell Atlantic will be notified of changes to
the DiaLinx network or access numbers via periodic e-mail updates. Genuity may
periodically add additional dial up access service categories as the DiaLinx
network evolves. These additional services and respective prices will be made
available on an on-going basis, via e-mail updates notifying Bell Atlantic of
the additional service. Use of such additional services by Bell Atlantic or Bell
Atlantic end users will be deemed Bell Atlantic's acceptance of the updated
service and pricing. For a current list of services, pricing, and dial up access
numbers associated with each service, please consult Genuity's Web page as
listed in the DiaLinx Service Description.

         All prices have been changed to MONTHLY, unless otherwise noted.

Notes:

(1)  Pricing excludes administration of customers' user authentication or
     accounting databases, VPN configuration on the firewall, and configuration,
     management, and administration of customer De-Militarized Zones (DMZ) which
     will be quoted on a Time and Materials (T&M) basis for each individual
     customer opportunity. These additional charges are not eligible for
     Multi-Service Discounts.

(2)  Installation Fee for Security Advantage is not eligible for Multi-Service
     Discounts.

(3)  The pricing set forth above for Security Advantage shall be effective upon
     execution of the Agreement. Genuity and Bell Atlantic shall review Security
     Advantage pricing on a quarterly basis. At each quarterly review Genuity
     shall notify Bell Atlantic (1) if it has experienced reductions in the
     operating costs applicable to the Security Advantage product or (2) if it
     has offered pricing to other purchasers of the Security Advantage product
     which is below the then current Bell Atlantic pricing. In the event Genuity
     has experienced such cost reductions, Genuity shall reduce the Bell
     Atlantic pricing for the Security Advantage product accordingly, to the
     extent such cost reductions are commercially practicable. In the event
     Genuity has offered other purchasers more advantageous pricing, Genuity
     shall reduce the Bell Atlantic pricing for the Security Advantage product
     to be at least as beneficial as such pricing. This pricing schedule shall
     be amended to reflect any such pricing reduction.

Notes:
------
A "standard service quotation" for purposes of this Attachment is one in which
all the MCS services and products purchased by Bell Atlantic or Bell Atlantic's
customer are found in the applicable MCS Service Description at the time the
quotation is generated.

Price lock-in per ordered connection:  Each new connection will be priced at the
-------------------------------------
baseline price in effect at the time the connection is originally ordered for at
least 12 months following its installation. Each renewed connection will be
priced at the baseline price in effect at the time the connection is renewed for
at least 12 months following its renewal. That means that when baseline pricing
changes, the new prices only apply to new orders and some subset of renewals. In
particular, in the case of renewals, new pricing will not be applicable unless
the connection's previous price had been in effect for at least 12 months.

     independently of this agreement, Bell Atlantic and/or its Services Supplier
     grants you a personal, non-exclusive, non-transferable license for the
     duration of the Service Period to use such software in object code form

     enabling you to use Enterprise Advantage Services.  You agree to accept any
     additional license terms required by the suppliers of such software as
     indicated in the Service Description.  You acknowledge and agree that title
     to all such software remains with the Services Supplier and its vendors, if
     any, that the content and design of such software are valuable trade
     secrets, and that you may use such software for the sole purpose of
     enabling you to use Enterprise Advantage Services.  You agree not to (a)
     disclose or make available to third parties any portion of such software
     without the advance written permission of the Services Supplier; (b) copy
     or duplicate such software; (c) reverse engineer, decompile or disassemble
     such software; or (d) modify or make derivative works of such software.
     You agree not to use such software after the Service Period without
     obtaining a valid license from the Services Supplier or from the third-
     party software vendor.  You also agree to accept any additional license
     terms required by the Services Supplier's vendors for the Enterprise
     Advantage options you have chosen.  All such license terms are set forth in
     the Service Description.

     If you purchase a software option in which you are responsible for
     acquiring the license and the Services Supplier agrees to install the
     third-party software for you, you are solely responsible for obtaining a
     valid license from the software vendor.  If the Services Supplier purchases
     any third-party software on your behalf, you agree to sign any required
     third-party license agreements prior to delivery or installation of the
     third-party software.  If Service Supplier installs third-party software at

     Dedicated Internet Access Network Service Level Agreements (SLAs) Violation
     and Remedies.

Genuity's failure to meet the following Network SLAs will result in a percentage
credit on the Bell Atlantic's bill for the following month for the affected
network. The SLA credit percentage is dependent on the number of consecutive
months of SLA failure and the degree of failure. Terms and metrics not otherwise
defined below will have the meaning set forth in the standard dedicated access
SLAs.

Note: Network Availability and Latency SLAs are mutually exclusive - for
example, a large latency timeframe would indicate a Network Outage.  A
percentage of the affected Bell Atlantic customers' total recurring monthly fee
will be remitted back to Bell Atlantic as indicated in the tables below.

Bell Atlantic will require access to Genuity's Stats Advantage system to be able
to verify Network Outage and Latency for Bell Atlantic customers.

** Remedy is a percentage credit to Bell Atlantic for the specific customer's
MRC for the next bill in Bell Atlantic's billing cycle.

*** Customers will also receive full credit of the NRC/Installation for
BizConnect if total installation takes * days or more.

If Genuity is not able to meet such requested provisioning date, Bell Atlantic
may, within five (5) business days, cancel Bell Atlantic order without incurring
cancellation charges. If Genuity is not able to deliver the services within *(*)
calendar days, Bell Atlantic has the right to terminate the service order
without penalty.

Delays caused by customer provided CPE shall not be factored into the SLA
compliance for any of the above-referenced SLAs. Orders shall be considered
"complete and accurate" if they meet the requirements specified by the PMO from
time to time.

Within * business days from the time Genuity receives a     25% off the standard installation fees for the Quotation
quotation request package from Bell Atlantic, Genuity       (provided Genuity wins the business)
shall either:

(i) issue a quote if the quotation request package for
standard EA services is complete and accurate; or

(ii) reject the quotation request package if it is
incomplete and/or inaccurate.  Genuity will also give
Bell Atlantic reasons for the rejection in a manner to
be mutually agreed upon in accordance with the
procedures under Section 3.2 of the Agreement.

A complete and accurate quotation request package
consists of a completed configuration template, a visio
diagram and a completed end-user questionnaire, all of
which have been approved by Genuity.

Note: If Genuity determines that the quotation process for Bell Atlantic is

     Genuity will make an Enterprise Advantage provisioning SLA available to
     Bell Atlantic (i) within 6 months of signing this Agreement, or (ii) when
     Genuity makes a provisioning SLA generally available to its web hosting
     customers, whichever is earlier.

     At the present time, Genuity anticipates that the EA provisioning SLA that
     will be provided to Bell Atlantic will be along the following lines:

          For all EA Service Quotations, Genuity will meet the delivery date
          given to Bell Atlantic upon completion of a successful kickoff
          meeting, including receipt by Genuity of a complete and accurate order
          package which has been approved by Genuity, for the EA Service
          Quotation. In the event that Bell Atlantic or Bell Atlantic's End User
          Customer has caused any delays that materially impact the provisioning
          process, the delivery date given by Genuity shall be void and this SLA
          shall not apply.

          Remedy if Genuity fails to meet the SLA:

          25% off the standard installation fees for the Quotation

     The actual EA Provisioning SLA will be mutually agreed-upon by the parties.

/1/ Assumes both orders are completed at submission and placed together at the
same time. SLA is based on standard provisioning intervals for IA and IAI.
Expedited or accelerated orders are excluded.

/2/ If one of the service elements is dependent on another service element that
has a longer provisioning element, (e.g., Internet Advantage, etc.) then the
longer provisioning interval is utilized. In some cases the intervals may be
additive if the provisioning one service is based on the completed provisioning
of another service. No more than 2 SLAscan be enacted per Bell Atlantic
customer.

/3/ Licensed countries refers to those countries where Genuity has secured an
import and/or operating license (where required) to deliver VPN service. Genuity
will provide post an updated list of Licensed Countries to the Genuity Kbank for
Bell Atlantic reference.

Provisioning timeframe does not start until all required network diagrams and
architectures (collectively "artwork") have been received by Genuity
Provisioning.  All applications are subject to a mandatory architecture review
prior to order acceptance.

If the customer is non-responsive after 3 consecutive phone calls from VPN
Provisioning, Bell Atlantic will be notified and the order will be placed on
hold and excluded from current or future provisioning SLAs for the affected
site(s).

Orders for international service will require customer cooperation in order to
complete export and import documentation for equipment delivery. If customer is
non-responsive after 3 consecutive calls from Genuity, Bell Atlantic will be
notified and the order will be placed on hold and excluded from current or
future provisioning SLAs for the affected sites.

the Projected Delivery Date.  Notwithstanding the immediately preceding
sentence, in the event Bell Atlantic notifies Genuity of any untimely
installation or non-operation of Bell Atlantic's or its End User's facilities,
equipment, or Services at least thirty (30) days prior to the Projected Delivery

disconnected due to security concerns provided that nothing in this Section
shall impact Genuity's rights under Section 21 of this Service Schedule.

plan that incorporates Bell Atlantic's training requirements.  This training
plan will include, but not be limited to quarterly product capability training,

seminars will be limited to Bell Atlantic headquarters employees, including
Marketing, Product Management, Operations, Engineering and Alliance Management.
Genuity will not provide training or technology seminars to Bell Atlantic's End

11. Access Support Services.  At Bell Atlantic's request, Genuity will order
    ------------------------
the LEC/CAP/ALT/IXC Access circuit for Bell Atlantic's End User on behalf of
Bell Atlantic, to  facilitate and coordinate the interconnection between the
Bell Atlantic End User demarcation and Genuity point-of-presence.  Genuity will
act in this capacity only when requested to do so by Bell Atlantic.  Under such
circumstances, Bell Atlantic agrees to execute or obtain from its End User a
Letter of Authorization in a form acceptable to the underlying carrier.  Genuity
shall provide firm fixed pricing for the Access circuits except where subject to
the underlying carriers' applicable tariffs.  Within a period of six (6) months
from the Effective Date of the Agreement, Genuity shall use commercially
reasonable efforts to obtain competitive pricing from the Genuity approved
Access providers (as specified in the Service Availability Report) for Access
charges

                                       4
<PAGE>

that shall be competitive with the prices from such Access providers to
Tier 1 carriers, including AT&T, Sprint, and MCI WorldCom to the extent that
Genuity aggregate volumes generate buying power is equivalent to the referenced
carriers.  If, upon the expiration of the six (6) month period, Genuity have not
obtained such competitive pricing, the Parties will jointly retain a mutually
agreed upon independent third Party no more frequently than a semi-annual basis,
to obtain and provide benchmarking information for similar Access.  The
independent third party will utilize the following criteria for conducting the
benchmarking review: purchasers of Access  who are similarly situated to Genuity
by comparable geographic reach and comparable volumes, and who deliver SLAs
comparable to those specified in the Service Schedule.  Genuity shall have
ninety (90) days after receipt of benchmarking information to meet the pricing
contained therein.  If Genuity fails to meet this pricing, then Bell Atlantic
shall be entitled to relief pursuant to Section 7.3 and Attachment 1 of the
Agreement.  The Parties shall review progress Genuity has made in completing
this process and upon mutual agreement, may extend the six (6) month period.
Genuity will provide Bell Atlantic Access pricing at Genuity's cost with no mark
up, using Genuity's special Access arrangements or tarriffs of the underlying
carrier(s), whichever is less and conforms with the requirements under this
Service Schedule.

The Parties acknowledge that it is their intention that Bell Atlantic should
enjoy network availability from LEC/CAP/ALT/IXC providers equivalent to the
Service SLAs detailed in Attachment A.  Genuity shall make commercially
reasonable efforts to procure such network availability SLA from LEC/CAP/ALT/IXC
providers.  In the event that Genuity is able to obtain from a LEC/CAP/ALT/IXC
provider a credit in the event that a given level of network availability is not
met, and Genuity's SLA remedies for network availability are not invoked, then
such credit shall be prorated to Bell Atlantic on the basis of actual Services
ordered by Bell Atlantic for such underlying carrier(s).  Genuity shall provide
to Bell Atlantic and keep updated a list of LEC/CAP/ALT/IXC providers that
guarantee a minimum level of availability for such services.  However, where a
LEC/CAP/ALT/IXC provider does not guarantee such availability, Genuity shall
have no liability to Bell Atlantic in the event that the LEC/CAP/ALT/IXC
provider fails to meet the availability target.  In such circumstances, Genuity
shall notify Bell Atlantic promptly of the availability that is being offered by
the LEC/CAP/ALT/IXC provider in question.

12. Pre-Sales Support.   In order to facilitate the quote and RFP process to
    -----------------
Bell Atlantic, Genuity will provide the following:

A.  Standard Quote Process Support for Access.  Genuity will provide pricing
quotes for Access as specified in Section 10 within the time required in the
SLAs.  Further details on this quote process, including identification of who
will submit and who will receive such quotes, will be mutually developed between
the Parties.  Within ninety (90) days after the Effective Date of the Agreement,
Parties shall complete a mutually agreed upon plan to define specifications to
automate/mechanize the quote process.

B.  Facilities Availability Inquiry.  Genuity will conduct facility availability
inquiries for Services within the time required in the SLAs.  Further details on
this inquiry process, including

                                       5
<PAGE>

identification of who will submit and who will receive such inquiries, will be
mutually developed between the Parties.

C.  Custom Bid Support.  Genuity will provide support as mutually agreed and
pricing to Bell Atlantic for bids which have requirements beyond the scope of
Services and functionality in the Service Schedule (a "Custom Bid").  Pricing
for the Custom Bid shall consist of mutually agreed pricing limited to the scope
of Services and functionality proposed in the Custom Bid.  Custom Bids include,
but are not limited to, customized responses relative to network operations or
installation requirements, network configuration, network buildout, significant
numbers of end user sites and/or significant bandwidth opportunities mix of U.S.
domestic and non-U.S. international cross border and/or non-U.S. domestic
venues, support of special billing arrangements and other similar extenuating
circumstances.

     1) Bell Atlantic shall submit to Genuity a Custom Bid Request in a form,
     which will be mutually agreed upon by the Parties within ninety (90) days
     after the Effective Date of the Agreement.  The Custom Bid Request form
     shall contain, at a minimum, the following information: a summary of the
     Custom Bids, technical specifications, and Bell Atlantic required response
     date.  The Custom Bid Request form will be reviewed and approved by Bell
     Atlantic management prior to submission to Genuity.
     2) Genuity will respond to Bell Atlantic within two (2) business days from
     the receipt of the request with a representation as to whether Genuity will
     respond to the request and if so, an estimated time of completion for
     responding to such request.
     3) Genuity is not primarily responsible for presentation of the Bell
     Atlantic response but will, at Bell Atlantic's reasonable request, support
     Bell Atlantic's response presentation;
     4) The Parties will enter into an addendum to this Service Schedule to
     cover each Custom Bid and its associated pricing agreed upon by the
     Parties, and the Parties will perform the same in accordance with the
     addendum.
     5) Any information provided by Bell Atlantic to Genuity for the Custom Bid
     shall be treated as confidential information in accordance with Section 9
     of the Agreement.

D.  Expedite Quotes Process.  Upon Bell Atlantic request, Genuity will use
    ------------------------
commercially reasonable efforts to expedite quotes for Customer Bid and Access
to accommodate Bell Atlantic End User requirements.

13. Order Entry and Provisioning.

A.  Order Process and Acceptance/Rejection Notification

To facilitate the ordering and provisioning of Services to Bell Atlantic, the
Parties will use mutually agreed processes for exchange of new, additional,
supplemental, change, pre-install cancellation and/or disconnect service orders.

procedures contained in this Section and Attachment D of this Service Schedule.
These procedures may be amended from time to time by mutual agreement of

                                       6
<PAGE>

both Parties. All such changes as agreed to by the Parties shall be made in
writing and incorporated into this Service Schedule. The following will be
applicable to all such Orders:

     Bell Atlantic will send Genuity a complete and accurate Order for each
     Service ("Order") in the form set forth in Attachment E as may be modified

     among other things, the date that Bell Atlantic requests Service be
     available for use ("Desired Due Date").   To the extent that the Service
     has a standard Installation Interval as described in Attachment A, the
     Desired Due Date shall be no earlier than the standard Installation
     Interval unless the Desired Due Date has been approved pursuant to the
     Installation Interval Expedite process set forth below.

     Within two (2) business days of receipt of the Order, Genuity will notify
     Bell Atlantic that it has either accepted or rejected the Order.  An Order
     may only be rejected if it is materially deficient or materially defective.
     Acceptance of the Order means that Genuity has approved of the form of the
     Order, e.g., the Order is complete, all fields are filled in, and that
     Genuity will commence processing the Order.  Notwithstanding the foregoing,
     if Genuity accepts an Order for End-to End Service on the good faith belief
     that it is complete and accurate, that Order may be subsequently rejected
     if the LEC/CAP/ALT/IXC notifies Genuity that the Order is materially
     defective or materially deficient.  If Genuity rejects the Order, the
     notice of rejection will provide an explanation for such rejection, e.g.,
     the Order lacks sufficient information and specific details of such
     deficiency.  Resubmission of a rejected Order constitutes the submission of
     a new Order for the purpose of Order processing.

     If Genuity has not responded to Bell Atlantic with a status of the Order
     within two (2) business days of Genuity's receipt of the Order, the Order
     shall be deemed accepted by Genuity.

It is mutually recognized that these processes will to some extent be manual as
of the Effective Date of the Agreement, and Genuity shall use commercially
reasonable efforts to expedite the mechanization of these processes.  To that
end, within ninety (90) days of the Effective Date of the Agreement, the Parties
will complete a mutually agreeable Order handling process which will incorporate
the following:

     Genuity will provide to Bell Atlantic in a mutually agreed manner
     mechanized access to the appropriate Genuity system(s) to allow for the
     transmittal of Bell Atlantic Orders to Genuity, the transmittal of Order
     acceptance notification, and rejection/jeopardy notification with detailed
     explanation(s) thereof. Any future Genuity systems development will
     incorporate all mutually agreed upon requirements for Bell Atlantic to
     submit Orders for provisioning at Genuity's expense.

B.  Firm Order Commitment

                                       7
<PAGE>

Genuity shall issue to Bell Atlantic a Firm Order Commitment (FOC) within the
following timeframes: within ten (10) business days of Genuity's acceptance of a
Bell Atlantic Order for PoP-to-PoP Service; within eleven (11) business days of
Genuity's acceptance of a Bell Atlantic Order for DS-3 or lower End-to-End
Service; and within fourteen (14) business days of Genuity's acceptance of a
Bell Atlantic Order for OC-N End-to-End Service.  Genuity will be relieved of
its obligation hereunder in the following circumstances:  a) reasonable outside
construction delays; and b) delays caused by LEC/CAP/ALT/IXC providers.  In the
event that Genuity determines prior to issuance of the FOC that it is unable to
provision an Order, Genuity shall promptly notify Bell Atlantic via email of the
specific reasons for such inability to provision the Order.  The FOC shall
contain the following information: the installation date for the full circuit or
Service as ordered by Bell Atlantic ("Projected Delivery Date"); the Bell
Atlantic circuit ID (as provided to Genuity on the Service Order from Bell
Atlantic); the Genuity circuit ID; and, the circuit ID(s) and delivery date(s)
for all Access and/or interexchange service(s) ordered by Genuity on behalf of
Bell Atlantic in support of the Service Order.  Issuance of the FOC shall
constitute Genuity's agreement to provision the Services in the applicable
Order.  Bell Atlantic and Genuity agree to work cooperatively to meet specific
Bell Atlantic requirements relative to Orders.

C.  Installation Interval Expedites

The Parties mutually agree that they will work together to facilitate requests
for installation intervals shorter than those otherwise agreed as standard on a
case-by-case basis.  The Parties will utilize the Expedite process Attachment F
to the Service Schedule within ninety (90) days of the Effective Date of this
Agreement.  Bell Atlantic shall be entitled to expedite the greater of ten
percent (10%) of all accepted but not installed Orders or five (5) accepted but
not installed Orders at any one time.

D.  Facility Orders via Third Parties

Genuity will issue all applicable Access Service Requests ("ASRs") to the
appropriate LEC/CAP/ALT/IXC.

In the event that Bell Atlantic requests Customer Provided Access (CPA) on one
or more ends of a circuit/Service, Genuity will provide the appropriate Circuit
Facility Assignment (CFA)/Letter of Authorization (LOA) within three (3)
business days of Genuity acceptance of a Bell Atlantic Order.  For purposes of
CPA, Bell Atlantic may only use Genuity approved Access providers for the
specific location as identified in the most current Service Availability Report
described in Section 8(A)(3) of this Service Schedule.

Genuity shall issue to Bell Atlantic a Circuit Layout Report (CLR) within the
following timeframes; ten (10) business prior to the Project Delivery Date for
PoP to PoP Service; and three (3) business days prior to the Projected Delivery
Date for End to End Service.  The CLR shall contain the following information:
Details regarding the layout of the service as ordered and pending delivery;
confirmation of Projected Delivery Date for the full circuit or service as

                                       8

ordered by Bell Atlantic; the Bell Atlantic circuit ID (as provided to Genuity
on the service order from Bell Atlantic); the Genuity circuit ID; and, the
circuit ID(s) and confirmed delivery date(s) for all local loop or interexchange
service(s) ordered by Genuity in support of the service order.

In the event that Genuity becomes aware of any issue(s) which would have an
impact on the Projected Delivery Date at any point prior to installation,
Genuity shall make Bell Atlantic aware of such issue(s) and work diligently with
Bell Atlantic and with Genuity's own provider(s) to resolve any such issue(s).

14. Change Control Process

The Parties recognize that over the term of the Agreement, Bell Atlantic may
desire to change the scope of the Services as set forth in the Agreement to
account for, among other things, changes in market circumstances, new
technologies and strategic considerations (hereinafter "Service Changes"). The
purpose of this Section is to provide an overall startup process for
accomplishing such Service Changes.

A.  Service Change Request

Right to Make Service Changes.  Genuity shall perform Service Changes requested
by Bell Atlantic in regard to a Service where the terms of the Service Changes
are mutually agreed to by the Parties in advance in writing ("Service Change
Request").  Genuity shall consider any Service Changes requested by Bell
Atlantic unless (i) Genuity considers, at its absolute discretion, that it is
not commercially practical for it to meet the requirements of Bell Atlantic (ii)
the scope of Services after implementation of the requested Service Changes
would differ materially from the purposes and objectives of the applicable
Service or (iii) the Parties have not reached agreement on any associated
adjustment (if any) to Genuity's compensation and/or schedule for the requested
Service Changes.  Where Genuity considers any Bell Atlantic request not
commercially practical, it shall give reasons therefor to Bell Atlantic and
shall work with Bell Atlantic to explore reasonable alternatives.

B.  Service Change Process

1)  Bell Atlantic Request.  The Bell Atlantic Project Manager shall submit
    ---------------------
requests for Service Changes to the Genuity Channel Manager in written form.
The Service Change Request shall contain information concerning the nature of
the requested change (setting forth the business requirements in sufficient
detail for Genuity to respond in a timely and effective manner) as well as a
date by which the Service Change is reasonably required.

2)  Genuity Response.  Within ten (10) business days after receipt of a Service
    ----------------
Change Request, Genuity shall deliver to Bell Atlantic a statement stating its
intention with respect to providing the requested Service Change and
implementation plans where appropriate or practical, as further described below.
In the event that the Genuity responds to Bell Atlantic to the effect that such
requested Service Change cannot be implemented in the time frame desired but
that Genuity

                                       9
<PAGE>

intends to implement such Service Change, Genuity shall set forth the time frame
estimates within which it could implement the Service Change.

3)  Bell Atlantic Approval.  Within a reasonable time following receipt of
    ----------------------
Genuity's Response Bell Atlantic shall provide a written direction to Genuity as
to whether or not it desires Genuity to perform the Service Change. Genuity
shall have no obligation to undertake Service Changes and Bell Atlantic shall
have no responsibility or liability in connection with any Service Changes
undertaken, without specific prior written agreement between the Parties.

C.  Service Change Pricing

The pricing for changing the Service, the pricing for the Service and the terms
and conditions under which the Service shall be provided to Bell Atlantic shall
be mutually agreed upon by the Parties in advance and in writing. Service Change
Pricing shall be consistent with the terms and conditions of this Service
Schedule and the Agreement.  In the event Genuity cannot determine price with
certainty at the time of the initial Genuity Response, Genuity shall use
commercially reasonable efforts to provide a good faith estimate of the pricing
associated with a given Service Change Request, and shall provide firm pricing
to Bell Atlantic as soon thereafter as practicable.

15. Cancellation of Orders/Order Supplements & Change Orders/Disconnection of

necessary to provide the Service.  Where Genuity provisions an End to End
circuit or End to Bell Atlantic network interconnect circuit, Genuity shall be
responsible for all trouble testing, isolation, coordination and resolution with
all LEC/CAP/ALT/IXC regarding expected Service restoration for the Genuity
provisioned elements as referenced above.  This responsibility includes opening
trouble reports with any LEC/CAP/ALT/IXC providing local and/or IXC facilities
provisioned by Genuity and performing joint testing with such Parties and Bell
Atlantic.  Bell Atlantic is responsible for coordinating any testing with non-
Genuity contracted Parties.  Genuity shall test Circuits upon installation as
detailed in Section 16 of this Service Schedule and in response to a trouble
ticket.  Within ninety (90) days of the Effective Date of the Agreement, the
Parties will complete a mutually agreeable test plan for repair which shall
include but is not limited to: scheduling parameters, interactive testing,
testing parameter details and the necessary documentation.

Genuity shall administer all trouble tickets referred by Bell Atlantic that
impact Bell Atlantic's purchased Services.  This includes tracking the progress
of the trouble ticket and providing status reports, and keeping a log of the
progress electronically.  Genuity shall contact Bell Atlantic with an
explanation of the trouble resolution and verify that the problem has been
corrected.  Genuity shall perform a mutual ticket closeout process with Bell
Atlantic. Bell Atlantic shall assist Genuity in conducting Service testing when
such is requested by Genuity.  Bell Atlantic shall close out the trouble ticket
with Genuity after Bell Atlantic verifies that the problem reported is resolved.
The trouble reporting process is set forth in Attachment G.  The repair process
flow is set forth in Attachment H.

Genuity shall provide a method for Bell Atlantic to periodically gain

C.  Immediately upon receipt of the Acceptance Certificate, Bell Atlantic may
carry out its own testing and commence use of the Service(s) in accordance with
Section 8 of this Service Schedule, for which the Acceptance Certificate has
been issued.

D.  Bell Atlantic will use all reasonable endeavors to test the service as soon
as possible, and to sign and return the Acceptance Certificate to Genuity as
notification of in accordance with this Service Schedule:

     (i)  Confirmation of the Initial Service Verification Tests being
     successfully completed; or

     (ii) Any failure of Bell Atlantic's own testing and the details thereof

     The Acceptance Certificate shall be signed by the Bell Atlantic's Project
     Manager, or such other authority as notified by Bell Atlantic in writing to
     Genuity.

E.  Bell Atlantic and Genuity will ensure that all facilities and assistance
reasonably required by either Bell Atlantic or Genuity shall be made available,
free of charge, to each Party for the performance of the Initial Service
Verification Test(s).

F.  Acceptance of the Services shall occur or be deemed to occur on the earliest
of the following:

     (i)    The date on which Bell Atlantic signs an Acceptance Certificate (in
            the format specified above); or

     (ii)   The close of business on the fifth (5th) business day following the
            day on which Genuity notifies Bell Atlantic that Genuity believes
            the Services have passed the Initial Service Verification Test in
            all material respects; unless, after the date of such notice and
            prior to the close of business on such fifth (5th) business day,
            Bell Atlantic provides a notice to Genuity that rejects the Services
            and sets forth in reasonable detail how the Services fail to satisfy
            the Initial Service Verification Test in one or more material
            respects; or:

     (iii)  The date the Services are put into operational use.

G.  If the Services are rejected in accordance with this Service Schedule,
Genuity shall be given such time and facilities as are reasonable in all the
circumstances to rectify the Services and repeat the Initial Service
Verification Test(s) or any part of them.  Genuity shall not be required to
repeat any tests included in the Initial Service Verification Test(s) which have
already been accepted or deemed accepted in respect of the Services.

H.  The Acceptance Certificate signed by Bell Atlantic does not relieve in any
way the obligation upon Genuity to carry out in full all its obligations under
this Agreement.

                                      19
<PAGE>

I.  Bell Atlantic and Genuity shall cooperate in performing Operational
Readiness Test (ORT) prior to launch of Service(s) in order to test process
flows and network availability. Prior to commencement of testing, Bell Atlantic
shall produce and provide to Genuity an ORT plan that will map out the
anticipated dates for meeting certain milestones in the ORT process, with an ORT
completion date being not later than ninety (90) days from the commencement of
testing. Genuity will produce a matching plan and deliver same to Bell Atlantic
within five business days of Genuity's acceptance of the Bell Atlantic-delivered
ORT plan. In addition, the ORT plan will detail the types of circuits and orders
that will be tested (in terms of speeds, destinations, etc.). The Parties shall
agree on the ORT plan prior to such commencement, and the Parties shall promptly
work together in good faith to resolve any issues raised by either Party and,
upon resolution, testing shall commence as soon thereafter as practicable.

J.  Testing of the operational support procedures shall be conducted at two
levels: (a) a non-physical testing which will ensure that End User orders are
generated properly and handled in an accurate and timely manner, and (b)
physical testing which will require the actual activation of a circuit,
maintenance and monitoring from Genuity over a mutually agreed to specified
period of time.  The ORT plan shall set forth methods for identifying problems
in either the process flows or in network availability, and for escalating all
identified problems within each organization for appropriate and timely
resolution.  For purposes of the actual testing of private line circuits Genuity
shall provide to Bell Atlantic one or more site addresses in Genuity served
regions in order to terminate the physical circuits.  During the ORT testing
period the operations and communications flows within Genuity shall be monitored
and reported to Bell Atlantic as defined and mutually agreed to in the ORT plan,
and any problems identified shall be remedied in an agreed time frame or
escalated for resolution, as necessary.

K.  Cooperative efforts around Market Readiness Testing (MRT), which involves
limited market introduction to Beta-customers, have to be agreed/detailed
between the Parties.

25. Network Review Meetings.  Bell Atlantic and Genuity agree to hold quarterly
    -----------------------
meetings or more frequently as mutually agreed, to work cooperatively on items
such as, but not limited to, forecast information, future network deployment
schedules, network enhancements, additional Access providers, Type II Access
arrangements, new services, performance reviews, defect resolution, business
processes and interaction, price reviews, and standards and specifications, and
Agreement performance.  Chairpersons to be designated by Bell Atlantic and
Genuity will jointly chair this effort.

26. Security.  Genuity shall administer access, both physically and
    --------
electronically, to all Genuity Network elements, associated support and/or
management systems, and physical PoP facilities that are under direct control of
Genuity. Genuity shall maintain all data associated with the security of the
Genuity Network. Genuity will use commercially reasonable resources and/or means
available to detect Genuity Network security breaches. Genuity shall use
commercially reasonable efforts to promptly provide pertinent information to
Bell Atlantic to assist Bell Atlantic in the identification and potential
prosecution of Network intruders. Genuity shall use

                                      20
<PAGE>

commercially reasonable efforts to promptly restore Genuity Network integrity
(not including End User databases) after Network intrusions. Genuity shall
provide protected storage of Genuity Network and Genuity Network element
configuration data. Genuity shall block and/or disconnect (as appropriate for
the Service) and with direction and/or authorization from Bell Atlantic, an End
User's access to the Network in which a security violation has occurred, at Bell
Atlantic request. Notwithstanding the foregoing, Genuity reserves the absolute
right to block or disconnect certain Services and/or connectivity if Genuity
reasonably believes that such Services/connectivity may affect Genuity Network
integrity or security; under such circumstances Genuity will provide notice to
Bell Atlantic of such action as soon as practicable and in advance where
feasible. Genuity shall provide access to Bell Atlantic for viewing of Bell
Atlantic Service data only as set forth in Section 15 of this Service Schedule.

27. Limited Warranty. The Genuity warranty is set out in Section 11 of the

    -------------------

A.  An Epidemic for a Service (e.g. ATM or Private Line) shall occur when the
elements in both subsections (i) and (ii) below have occurred with respect to
the affected Service:

(i) Failure of the greater of (a) the minimum number of circuits per Service or
(b) the minimum percentage of circuits per Service (as specified in the table
below) to meet certain network performance criteria.

     -------------------------------------------------------------------------
          Year                    Minimum Number of       Minimum Percentage of
                                  Circuits per Service    Circuits per Service
     -------------------------------------------------------------------------
          1                       10                      20%
     -------------------------------------------------------------------------
          2                       25                      20%
     -------------------------------------------------------------------------
          3 and thereafter        50                      20%
     -------------------------------------------------------------------------

          (a)  The applicable network performance criteria for Private Line
               Service shall consist of the following Private Line Service SLAs,
               which are contained in Attachment A:

               -    Time to Restore Time
               -    Circuit Availability
               -    Auto Restore Time

          (b)  The applicable network performance criteria for ATM Service shall
               consist of the following ATM Service SLAs, which are contained in
               Attachment A:
               -    Average Network Availability
               -    Per PVC Network Availability
               -    Average Cell Loss Ratio
               -    Per PVC Cell Loss Ratio
               -    Peak to Peak Cell Delay Variation

                                      21
<PAGE>

(ii) No more than fifty percent (50%) of the circuits experiencing SLA failure
may originate on a single node or among two (2) Adjacent nodes. For purposes of
this calculation, a node cannot be deemed Adjacent to more than one other node.
In the event of a multiple Adjacency, the node with the highest percentage of
circuits experiencing SLA failure will be the node utilized for purposes of this
calculation (e.g., 3 adjacent nodes will be treated as two (2) nodes for this
calculation; as between those two (2) nodes, the calculation will be made using
the two (2) nodes with the highest percentage of circuits experiencing SLA
failure). For purposes of this section, a "node" shall mean an ADM for Private
Line Service and a switch for ATM Service.

B.   If a Service experiences an Epidemic for two (2) consecutive months, Bell
Atlantic may give written notice to Genuity during such Epidemic that Genuity
has thirty (30) days to cure the Epidemic.  If Genuity does not cure the
Epidemic within thirty (30) days of receiving such written notice, Bell Atlantic
may terminate the affected Service.   Election of this remedy supercedes any
other applicable SLAs for the terminated Service as of the date of election.
Any reduction in the Purchase Commitment shall be governed by the applicable
sections of the Agreement.  To the extent Services are terminated, the Purchase
Commitment reductions shall only apply with respect to services comparable to
the terminated Service under this Service Schedule.  Nothing herein shall limit
either party's right to conduct an audit pursuant to Section 14.12 of the
Agreement.  The Purchase Commitment reduction for termination for a Service
resulting from an Epidemic shall be based upon the most current product-specific
forecast projected to the end of the Term for such Service or twenty percent
(20%) of the balance of the Purchase Commitment at the time of Service
termination, whichever is greater.

29.  Service Level Agreements for Services.  Genuity will meet the Service
     -------------------------------------
Levels specified in Attachment A to this Service Schedule. If Genuity fails to
meet the SLAs, Bell Atlantic shall be entitled to associated remedies specified
in Attachment A and Section 28 above. The SLAs shall not apply in the event of
Force Majeure, Planned Outages or Bell Atlantic and/or Bell Atlantic's End Users
actions that materially impact Genuity's ability to meet the SLAs. The SLA
remedies identified herein shall be Bell Atlantic's sole and exclusive remedy
for SLA failure, except for the following: (i) Genuity's gross negligence; (ii)
Genuity's willful misconduct; (iii) Genuity's indemnity obligations for
infringement pursuant to Section 10.1 of the Agreement; (iv) Genuity's
confidentiality obligation pursuant to Section 9 of the Agreement; (v)
imposition of fines or penalties on Bell Atlantic by any regulatory agency to
the extent imposition of such fines or penalties is caused by Genuity's SLA
failures.  Both Parties agree to monthly review meetings to discuss Service
Level performance related issues.  Genuity agrees to initiate and coordinate the
monthly review meetings.

1.   SONET Based Private Line Transport Service Overview

SONET Based Private Line Transport Service ("Private Line" or "Private Line
Service") products are point to point services derived from the basic SONET
building block of the Genuity backbone. Synchronous optical network (SONET)
defines optical carrier (OC) levels and electrical equivalent synchronous
transport signals (STS) for fiber optic based transmission hierarchy. It is a
standard specified by the Exchange Carriers Standards Association (ECSA) for
American National Standards Institute (ANSI). SONET uses a basic transmission
rate of STS-1 equivalent to 51.84 Mbps.

Higher rate transmissions are integer multiples of this base rate. Many types of
services ranging from voice to high-speed data and video are transmitted using
this format.

SONET provides the scalable bandwidth to transport information from one point to
another at a variety of speeds. Private Line Services can support the transport
of protocol services applied to voice or data service such as IP, ATM and Frame
Relay. These in turn support a range of applications used by Bell Atlantic
and/or Bell Atlantic End Users.

2.   Product Features and Functionality

2.1  High Level Functionality

There are three principal classes of service of Genuity Private Line Services
available each with a subset of configurations.

a.   End to End
b.   Access Hub to Access Hub
c.   Genuity POP to Genuity POP - This will become available with the
     introduction of direct optical connect and collocation as may be set forth
     in future amendments to the Agreement.

2.2  Product Features Set

Genuity is offering Private Line Services that include DS-3, OC-3, OC-12, OC-48
speeds.  The OC-3, OC-12, circuits may be concatenated, as well.

Genuity products will make use of the SONET pointer capabilities to dynamically
align VT and STS payloads, thereby permitting easy dropping, inserting and cross
connecting of payloads in the network. Additional use of the SONET capabilities
will be drawn on to provision 1+1 capabilities to support wholesale customer
demands.  The SONET rings on the Genuity backbone are four (4) fiber Bi-
Directional Line Switch Ring (BLSR).

2.3  Interconnection and Access

Bell Atlantic's interconnection to the Genuity network may be at the Access Hub
or Genuity POP.   The standard interconnection option for Bell Atlantic customer
provided access (CPA) services is at the Access Hub.  The Genuity backbone is
exclusively optical.  For Access Hub to
<PAGE>

Access Hub and Genuity POP to Genuity POP, Bell Atlantic is responsible for
access. The End to End Service includes Access in accordance with the terms in
the Service Schedule.

2.4.6  Auto Restoral Time
<PAGE>

The Auto Restoral Time for a Private Line circuit (POP to POP only) on a SONET
ring is 50 - 110ms.  The SLA Credit/Remedy for Auto Restoral Time is accounted
for in the Circuit Availability SLA set forth in this document.  Auto Restoral
Time is not a parameter that is directly measured for SLA crediting.

2.4.7  Latency SLA Credit/Remedy

The Genuity SONET based Private Line Service is designed to meet the latency
requirements as shown in Table 2.4.1-1.  Latency is a function of circuit miles
traversed.  The one-way network latency is measured from the ingress interface
at the entry Genuity POP to the egress interface at the exiting Genuity POP.

Genuity shall agree to test latency on any circuit upon written request of Bell
Atlantic.  If the latency constitutes an SLA failure, Genuity shall have thirty
(30) days from the date of test completion to make the circuit SLA compliant.
If the latency is SLA compliant, Bell Atlantic agrees to reimburse Genuity for
commercially reasonable costs of the testing, not to exceed $1,000 plus travel
costs per test performed.  Bell Atlantic will have the option to request latency
test(s) on 1% of the installed circuit base or 5 per month, whichever is
greater. This SLA does not cover route specific requests from Bell Atlantic.

2.4.8  Installation Intervals SLA Credit/Remedy

If the actual installation date is more than five (5) business days beyond the
Projected Delivery Date contained in the FOC, Genuity shall waive the access
facility installation NRCs associated with the installation.  In addition, if
the actual installation date is more than fifteen (15) business days beyond the
Projected Delivery Date, Bell Atlantic has the option to cancel the Order with
no cancellation charges.

1.1 ATM Product Overview

     ATM is a high-bandwidth, fast-packet switching technology based on fixed-
length cells of 53 bytes.  ATM combines the statistical multiplexing
efficiencies of packet-switching with the low delay characteristics of circuit
switching technologies.   This document summarizes the ATM Transport Service
("ATM" or "ATM Service") and service level agreements (SLAs) provided by the
Genuity network for Bell Atlantic.

                Section 2   PRODUCT FEATURES AND FUNCTIONALITY

2.1 High Level Functionality Description

     Genuity ATM transport establishes ATM connections between a Bell Atlantic's
End User site and one or more locations, including, as applicable, a network
interconnection with Bell Atlantic. Each connection will be a permanent virtual
channel (PVC) or a permanent virtual path (PVP). Each supported ATM virtual
connection is a point-to-point (or point-to-interconnect) connection.  Genuity
ATM is connection-oriented, cell-based data transport capable of physical access
interconnection speeds from DS-3 to OC-12c Genuity, on an individual case basis,
will work to develop alternatives to provide Bell Atlantic customers lower speed
physical interconnections to the Genuity network when business economics
warrant.

2.2  Product Feature Set

2.2.1  Physical Connections

     The customer interfaces to the ATM Transport through DS3 (un-channelized),
OC-3c or OC-12c interfaces

     ATM cell formatting and traffic policing are compliant with the ATM Forum
UNI v3.0/3.1 Specifications.

2.2.2  Virtual Connections

The ATM Transport supports the following categories of traffic for virtual
connections:

                                       1
<PAGE>

A.  Constant Bit Rate (CBR): An ATM category that supports a constant or
    guaranteed rate to transport applications, such as video distribution, that
    require rigorous timing control and performance parameters. The traffic
    parameters associated with CBR are Peak Cell Rate (PCR), Cell Transfer Delay
    (CTD) and Cell Delay Variation (CDV).

B.  Real Time Variable Bit Rate (VBR-rt): The real-time VBR category is intended
    for time-sensitive applications (i.e., those requiring tightly constrained
    delay and delay variation), such as interactive multimedia. Sources are,
    however, expected to transmit at a rate that varies with time. Traffic
    parameters are PCR and Sustainable Cell Rate (SCR). Cells that are delayed
    beyond CTD are assumed to be of significantly less value to the application.
    Default value for PCR is set at 1.4 times SCR. Maximum Burst Size (MBS) is
    also a traffic parameter for the real-time VBR with a default setting of 100
    cells.

C.  Non-Real-Time Variable Bit Rate (VBR-nrt): The non-real time VBR category is
    intended for applications which have bursty traffic characteristics and do
    not have tight constraints on delay and delay variation. Like VBR-rt, VBR-
    nrt traffic parameters are PCR and SCR. For those cells that are transferred
    within the traffic profile, the application expects a low CLR. Default value
    for PCR is set at 2.0 times SCR. Maximum Burst Size (MBS) is also a traffic
    parameter for the non-real time VBR service categories with a default
    setting off 100 cells

D.  Unspecified Bit Rate (UBR): An ATM category that does not specify traffic
    related performance guarantees. Specifically, UBR does not include the
    notion of a per-connection negotiated bandwidth. No numerical commitments
    are made with respect to the CLR experienced by a UBR connection, nor to the
    CTD experienced by cells on the connection.

For both PVC and PVP transport, the traffic profile may be subscribed for each
direction of the connection independently. The values for the parameters
indicated above are set forth in the data gathering form negotiated with the
customer. For the PVP option, the subscribed traffic profile must be able to
satisfy the QoS of the most demanding virtual channel connection (VCC) that may
be carried on that virtual path connection (VPC).

2.3  Technology Overview

2.3.1  Genuity ATM Switches
Genuity selected the Ascend models CBX-500 & GX-550 switch as its core network
ATM switches.

2.3.2  Integrated Local Management Interface (ILMI)
The Genuity ATM transport is compliant with the following ATM Forum
specifications:

A.   ATM User-Network Specification V3.0, af-uni-0010.001, ATM Forum Technical
Committee, Sept 1993
B.   ATM User-Network Specification V3.1, af-uni-0010.002, ATM Forum Technical
Committee, 1994
C.   ILMI 4.0, af-ilmi-0065.000, ATM Forum Technical Committee, Sept 1996
Bell Atlantic's and Bell Atlantic's End Users' ATM equipment must be similarly
compliant with the above specifications.

2.4  Product Functionality

2.4.1  Asymmetric PVCs
PVCs are bi-directional circuits, and typically but not necessarily, these
parameters are configured to be the same information rates in both directions.
However, the business needs of Bell Atlantic may require that additional
bandwidth be allocated in one direction and not the other direction. Genuity's
ATM transport enables Bell Atlantic to provision and price PVCs, as two unique
asymmetric PVCs, with different information rates between its locations.

2.4.2  Performance and Reliability Requirements

2.4.2.1  Network Availability
The Genuity ATM transport is designed meet the availability requirements as
shown in Table 2.4.4-1. A connection is considered available if it is possible
to transmit bits through the connection.

For each Point of Presence to Point of Presence (POP-to-POP) connection,
availability values are from the ingress interface at the entry on-right of way
Genuity POP to the egress interface at the exit on-right of way Genuity POP, and
include any on-right of way back-haul between the points of Bell Atlantic/Bell
Atlantic End User interconnection and the Genuity's ingress/egress ATM switches
for each ATM network ordered by Bell Atlantic hereunder (i.e. Interconnection
point(s) to the Bell Atlantic network are considered as POP/POP equivalent(s)).

                                       2
<PAGE>

For each End-to-End connection, availability values are from the network entry-
point, CSU/DSU, at the Bell Atlantic End User's premise to the network exit-
point, CSU/DSU, at the Bell Atlantic's End User premise. To provide this level
of transport, Customer Premise Equipment must be certified for compatibility on
the Genuity network.  Customer premise equipment requiring certification
includes, but is not limited to, CSU/DSU equipment and routers.  Genuity follows
the Lucent certified list of CPE vendors. These vendors include, but are not
limited to: Cisco, Nortel Networks, 3Com, Adtran, and Visual Networks (i.e. End-
to-Interconnection point(s) to the Bell Atlantic network are considered as End-
to-End-equivalent(s)).

As additional requirements are identified, Genuity will make commercially
reasonable efforts to augment the list of certified vendor equipment based on
market demand.

2.4.2.2  Cell Latency
Network latency or end-to-end delay is largely a function of circuit miles
traversed.  The one-way network latency is measured from the ingress interface
at the entry Genuity POP to the egress interface at the exiting Genuity POP.

The Genuity ATM network is designed to meet the latency values shown in Table
2.4.4-1

2.4.2.3  Cell Loss
The cell loss ratio (CLR) for ATM transport is defined in the ATM Forum Traffic
Management Specification, Version 4.0 (af-tm-0056.000).  Cell Loss Ratio is the
(total cells lost) divided by (total cells delivered).  The Genuity ATM network
is designed to meet the cell loss ratio values shown in Table 2.4.4-1

Cell loss due to saturation of an oversubscribed/1/ egress port is not
considered a failure on Genuity's part to meet the CLR performance
characteristics.

2.4.2.4  Peak to Peak Cell Delay Variation
The Genuity ATM network is designed to meet the peak-to-peak CDV values shown in
Table 2.4.4-1

2.4.2.5  ATM Maximum Burst Size
The default values for VBR-rt and VBR-nrt maximum burst size is 100 cells.  On
an individual case basis, requests for higher values will be reviewed for
feasibility.

2.4.2.6    ATM Over-subscription Parameters
Genuity ATM transport will allow port over-subscription values for VBR-rt and
VBR-nrt.

                        Transport Element              Value

                             SCR                       200%
                       --------------------------------------
                             PCR                       500%
                       --------------------------------------

Note these numbers represent the total port bandwidth allocations, but that they
may not all be simultaneously active at the same time.

2.4.3  Fraud Control Requirements
The primary goal of the Genuity's network security architecture is to protect
Genuity resources and reputation by securing its infrastructure and operations.
Protection of end user's traffic and sites is not a Genuity responsibility;
rather it is an end user responsibility.

/1/ In this statement "Oversubscribed" is defined as when the aggregate
equivalent bandwidth for circuits requested on a port exceeds the port's
capacity to carry all such circuits simultaneously.

hereunder for Bell Atlantic and Bell Atlantic's End User's.  Network
calculations are measured as average network availability and average cell loss
rates. Calculations are made separately on each ATM network and each ATM circuit
ordered by Bell Atlantic.

2.4.4.4  Remedies for Average Network Availability and Average CLR SLA
Genuity's failure to meet the Average Network Availability and/or CLR SLAs will
result in a percentage credit on Bell Atlantic's ATM bill for the following
month for the affected ATM network. The SLA credit percentage is dependent on
the number of consecutive months of SLA failure and the degree of failure.

-----------------------------
/2/ Bell Atlantic may select only one of the 3 (POP-to-POP or the End-to-End)
average network availability credits each month.  GNI will compute proactive
credits each month based on the POP-to-POP availability.
/3/ The End-to-End with High Availability Tails Network Availability SLA
requires that a Bell Atlantic purchase SONET local loops.   High availability
local loops are not available to all Bell Atlantic End User locations.
/4/ Customers may select only one of the 3 (POP-to-POP or the End-to-End) per
PVC network availability credits each month.

                                       4
<PAGE>

The number of consecutive months creates the base credit percentage and the
degree of failure creates a multiplier. If the SLA failure is for one single
month or for two consecutive months, then the base credit percentage is two
percent (2%). If the consecutive SLA failure continues for a third or fourth-
consecutive month, then the base credit percentage is four percent (4%). If the
SLA failure continues for a fifth or greater consecutive month, then the base
credit percentage is six percent (6%).

The following sets forth the multipliers:

i)   For the Average Network Availability SLA, the multiplier is the number of
     tenths below the average network availability parameter set forth in Table
     2.4.4-1; and

ii)  For the CLR SLA, the multiplier is the number of power of tens (1 x 10/+1/)
     above the SLA value for the class of service as specified in Table 2.4.4-1.
     With the first power of ten increase in CBR and VBR-nrt representing a
     failure to meet the SLA Infraction Level.

2.4.4.5  SLA Credit Policies

The following SLAs on a POP to POP basis will be proactively credited, and are
based on the Monthly Network Throughput and Network Availability Threshold
Report Records: Average Network Availability and Average Cell Loss Ratio.  All
other SLA remedies will be applied upon Bell Atlantic request and verification
by Genuity of SLA failure. Upon Bell Atlantic request, per Circuit credits will
be verified and applied in the amount by which the aggregate Per Circuit SLA
Credits exceed the Network level credit.

2.4.4.6  Verification of Non-Compliance

Genuity is responsible for verifying SLA non-compliance, not later than the
calendar month following the SLA failure, prior to crediting a customer's
account.

2.4.4.7  Time to Restore

Genuity will use commercially reasonable efforts to keep the Time to Restore
(TTR) under four hours (95% of the time) as measured over a one month period.
TTR is not a parameter that is directly measured for SLA crediting, however TTR
by its very nature is a factor in the computation of the overall Average Network
Availability

2.4.4.8  Exclusions from computation of SLA Failures

Each timeframe with data exclusion will be reflected as such in the Summary
Circuit Records. Oversubscribed circuits are eligible for Availability
Performance credits, however oversubscribed circuits are not eligible for Cell
Loss Violation credits. See the Section entitled "Service Level Agreements for
Services" in the Service Schedule for all other authorized exclusions in
addition to any other exclusions specifically identified.

2.4.4.9  CLR Allowance for Sample Period Errors

Computation of CLRs is based on reading and aggregating ingress and egress ATM
cell count statistics across each ATM network ordered by Bell Atlantic
hereunder. An allowance is made for cells in transit and cells not accounted for
due to the switches operating with timing set utilizing the Network Timing
Protocol (NTP) or equivalent level of accuracy.

2.4.4.10  Action Required of Genuity after 2 Months of Circuit Performance
          Violations

If an ATM circuit fails to meet the Per PVC Availability SLA and/or Per PVC CLR
SLA for two (2) consecutive months, Genuity will use commercially reasonable
efforts to coordinate (with Bell Atlantic approval) an alternate connection
until such time as the original connection meets such SLA performance standards.
Prior to reaching this two month maximum period Genuity may at its sole
discretion exercise these same provisions.  In the event Genuity performs
pursuant to this provision Genuity is relieved from its obligations set forth
below in 2.4.4.11.

2.4.4.11  Bell Atlantic Right to Terminate Networks

For Bell Atlantic End Users with ATM networks that operate for 3 consecutive
months or 5 months out of any 12 months with Average Network Availability and/or
Average Network CLR SLA failure violations, Bell Atlantic has the option to
terminate the affected End User ATM network without liability, except for
charges incurred prior to discontinuance.  Should Bell Atlantic decide to
terminate such Service, Bell Atlantic must provide written notice to Genuity of
its intent to disconnect no later than 30 days following the conclusion of the
3/rd/ consecutive month or 5/th/ month out of any 12 month period of Service
with such SLA violations.

2.4.4.12  Bell Atlantic Right to Terminate Circuits

For Bell Atlantic End Users with circuits that operate for 3 consecutive months
or 5 months out of any 12 months with Per PVC Availability and/or Per PVC CLR
SLA failure violations, Bell Atlantic has the option to terminate the affected
circuits without liability, except for charges incurred prior to discontinuance.
Should Bell Atlantic decide to terminate such circuits, Bell Atlantic must
provide written notice to Genuity of its intent to disconnect no later than 30
days following the conclusion of the 3/rd/ consecutive month or 5/th/ month out
of any 12 month period of service with SLA violations. Circuit terminations due
to Cell Latency or Peak to Peak Cell Delay Variation SLA failure conditions are
described in sections 2.4.4.15 and 2.4.4.16.

2.4.4.13  Per Virtual Circuit CLR Remedies

Notwithstanding the provisions contained in 2.4.4.14, 2.4.4.15, 2.4.4.16;
credits for individual PVCs and PVPs that exceed the Per PVC Cell Loss Ratio SLA
failure shall be equivalent to 50% of the MRC for the impacted PVCs.

2.4.4.14  Per Virtual Circuit Availability Remedies

Credits for individual PVCs and PVPs that exceed the Per PVC Availability SLA
failure level shall be the percentage of MRC specified in the tables 2.4.4.14-1
through 2.4.4.14-3 below. Per Virtual Circuit credits

                                       7
<PAGE>

are not additive, however Bell Atlantic may select the higher of the two credits
that apply to a circuit that has exceeded both a POP to POP and an End to End
SLA failure level.

2.4.4.15  Cell Latency SLA Remedies

Genuity shall test Bell Atlantic's circuits from POP to POP or End to End to
verify Cell Latency performance upon request of Bell Atlantic.  If the Cell
Latency is within SLA, the cost of the testing shall be assessed to Bell
Atlantic. In this event, Bell Atlantic shall reimburse Genuity commercially
reasonable costs of the testing, not to exceed $1000 plus travel costs for each
test performed.  If the Cell Latency is not within SLA, Genuity shall have 30
days from the date of Bell Atlantic's trouble report to restore the Cell Latency
to comply with the SLA.  If Genuity can not restore the Cell Latency, Bell
Atlantic shall have the right to terminate the affected circuit at no cost.

2.4.4.16  Peak to Peak Cell Delay Variation SLA Remedies

Genuity shall test Bell Atlantic's circuits from POP to POP to verify Peak to
Peak Cell Delay Variation performance upon request of Bell Atlantic.  If the
Peak to Peak Cell Delay Variation is within SLA, the cost of the testing shall
be assessed to Bell Atlantic. In this event, Bell Atlantic shall reimburse
Genuity commercially reasonable costs of the testing, not to exceed $1000 plus
travel costs for each test perfomed.  If the Peak to Peak Cell Delay Variation
is not within SLA, Genuity shall have 30 days from the date of Bell Atlantic's
trouble report to restore the Peak to Peak Cell Delay Variation to comply with
the SLA.  If Genuity can not restore the Peak to Peak Cell Delay Variation, Bell
Atlantic shall have the right to terminate the affected circuit at no cost.

2.4.4.17  Installation Interval SLA Remedies

If actual installation date is more than 5 business days beyond the Projected
Delivery Date contained in the FOC, Genuity shall waive the access facility
installation NRCs, associated with the installation.  In addition, if actual
installation date is more than 15 business days beyond the Projected Delivery
Date, Bell Atlantic has the option to cancel the Order with no cancellation
charges.

                                       8
<PAGE>

Since the computation of CLRs is based on reading and aggregating ingress and
egress ATM cell count statistics across the network, a dropped cell allowance is
made for cells in transit that are computed as lost cells due to Protection
Switchover (1 second of lost data per protection switch event).

        Section 4  Terms and Conditions associated with the ATM Pricing

ATM transport is provided as a distance insensitive capability. PVCs and PVPs
are priced unidirectional.  The Peak Cell Rate (PCR) of VBR PVCs and PVPs is
governed by the SCR ordered Bell Atlantic: in the flat rate PVC/PVP offering,
VBR-rt PCR is 1.4 multiplied by the SCR; and the VBR-nrt PCR is 2.0 SCR.
Request for PCRs with multipliers greater than those stated above shall be
supported at an increased cost.  UBR transport is only available in conjunction
with the active use of another ATM transport category on the same port and is
limited to 40 Mbps.  Maximum burst size (MBS) is limited to 100 cells. Request
for larger burst sizes shall be supported at an increased cost.

ATM - PVC Mapping and Configuration
================================================================================
*Note* -A key element to remember when requesting ATM-PVCs. With GNI each PVC is
uni-directional. If your customer requires a bi-directional PVC from one
location to another, you will need to enter an order for 2 PVCs; one for each
direction. When you enter the PVC # use a Number/Letter combination to relate
them (ex. 1A and 1B, 2A and 2B, 3A and 3B, etc.)

                                EXPEDITE PROCESS

STEP 1: IF BELL ATLANTIC REQUIRES A SERVICE INTERVAL OF LESS THAN THE STANDARD
INTERVAL IN THE SERVICE SCHEDULE, BELL ATLANTIC SHALL COMPLETE THE ATTACHED
EXPEDITE REQUEST FORM (ERF) AS MAY BE MODIFIED BY GENUITY FROM TIME TO TIME AND
FORWARD IT TO THE GENUITY CHANNEL MANAGER.  EXPEDITES WILL NOT BE ACCEPTED FOR
AN INTERVAL OF LESS THAN TEN (10) BUSINESS DAYS FOR NEW ORDERS, AND WILL NOT BE
ACCEPTED FOR AN INTERVAL OF LESS THAN FIVE (5) BUSINESS DAYS FOR CHANGE ORDERS.

Step 2: Genuity will convey the acceptance or rejection of the request to Bell
Atlantic within three (3) business days of Genuity's receipt of Bell Atlantic's
request.  If the request is accepted, the response will include Genuity's
ability to meet the expedited due date or such other date as Genuity is able to
meet.  If the request is rejected, Genuity shall provide the specific reason(s)
for the rejection.

Step 3: If Bell Atlantic accepts the Genuity expedite, Bell Atlantic will notify
Genuity within one (1) business day of such acceptance and the expedite fee will
apply as follows:

Expedite Fees:
     Bandwidth          New Orders      Change Orders

     DS3               $1,000           $  500
     OC3/OC3c          $1,500           $  750
     OC12/OC12c        $2,500           $1,250
     OC48+             $4,500           $2,500

Step 4: Bell Atlantic will place the Order with the approved expedited due date.

NOTES:
1.  GENUITY WILL FULLY WAIVE THE EXPEDITE FEE TO BELL ATLANTIC IF THE APPROVED
    EXPEDITED DUE DATE IS MISSED.

2.  Expedite requests on any pending Order will be accepted until the FOC is
    issued.  If Bell Atlantic decides to expedite a pending Order, the expedite
    process will take effect, rendering the previous Order null and void.

                               Trouble Reporting

When reporting a fault to the Genuity GNOC, Bell Atlantic shall supply as much
diagnostic information as it reasonably has available. Genuity will initiate
fault reporting directly when it is reasonably able to do so.

Genuity shall utilize industry-standard fault detection tools. When a fault is
detected, such fault will be logged by Genuity GNOC staff. Genuity shall also
utilize industry standard fault management tools, and will notify Bell Atlantic
from time to time of any modification to the tools it is deploying.

The Genuity GNOC shall be responsible for resolving the fault, and shall
maintain auditable records of all such resolutions. At all stages during the
fault resolution process, the Genuity GNOC shall remain the single point of
contact for Bell Atlantic. The Genuity GNOC will provide regular status updates,
according to accepted industry standards, as a reported fault progresses toward
resolution. Genuity shall categorize all faults in accordance with the severity
levels indicated in the Severity Level Matrix below. Upon identifying a fault or
a non-conforming condition, the Genuity GNOC will categorize the incident
according to its agreed severity in accordance with the Severity Level Matrix.
Where appropriate, Bell Atlantic will consult with the Genuity GNOC as to the
potential business impact and may verbally or electronically require a
modification to the severity level accordingly.

Fault tickets shall only be closed by Genuity when Bell Atlantic has confirmed
trouble resolution. Fault summaries and Fault status will be provided to Bell
Atlantic on a daily, weekly and monthly basis by the Genuity GNOC.

Severity Level Matrix
The severity matrix below indicates the level of urgency for an event:

------------------------------------------------------------------------------------------------------------------------------------
1.   GNI systems will use Simple Network Management Protocol (SNMP), to access partner's network for service, configuration, fault
     and performance information, on a near real time basis.
2.   Statistical information must be available and refreshed in an agreed upon discrete interval (For example, every 15 minutes.
3.   Fault information should be available in the form of a SNMP trap. The trap must be available within a minute of its occurrence.
4.   Configuration information must be refreshed at least, once every twenty-four hours.
5.   Partner must retain the statistics and fault history at least up to 5 days. It is also preferred if the information is
     available via industry standard interfaces such as ODBC.
6.   Bell Atlantic Global Networks, inc., recommends that partners deploy highly available systems architecture for information
     access.

                   PURCHASE, RESALE AND MARKETING AGREEMENT
                               SERVICE SCHEDULE
                    PURCHASE OF CAPACITY ON UNDERSEA CABLES

This Service Schedule is issued under the Purchase, Resale and Marketing
Agreement between Bell Atlantic Corporation ("Bell Atlantic") and Genuity
Solutions Inc. ("Genuity") dated ____________ ("the Agreement"). As stated
below, the terms and conditions of the Agreement are incorporated herein by
reference and made a part hereof. In the event of a conflict between the terms
of this Service Schedule and the Agreement, the terms of this Service Schedule
shall prevail. Capitalized terms are defined in the Agreement. Pursuant to
Section 1.1 of the Agreement, Genuity designates GTE Intelligent Network
Services Incorporated as the Service Provider for provision of the undersea
capacity Services under this Service Schedule.

1.   Capacity on ARCOS-1 Undersea Cable. Genuity will provide to a Bell Atlantic
     ----------------------------------
Authorized Affiliate capacity in the amount of an STM-1 on the Americas Region
Caribbean Ring System undersea cable ("ARCOS-1"), at Genuity's cost. Such cost
will reflect a pro rata share of the costs incurred by Genuity associated with
ARCOS-1, based on the percentage that the STM-1 constitutes of Genuity's total
number of STM-1s (or equivalent) on ARCOS-1. The costs will include, but are not
necessarily limited to, charges imposed under the ARCOS-1 Construction and
Maintenance Agreement and collocation at the cablehead. Within five (5) business
days of availability of undersea capacity Service on ARCOS-1, Genuity will
provide the Bell Atlantic Authorized Affiliate with additional details
concerning the costs and processes for provisioning such Services. The agreement
set forth in this Service Schedule is based on the fact that the Genuity
capacity commitment on ARCOS-1 was based in part on a commitment for the
specified STM-1 by a Bell Atlantic affiliate. Provision of the capacity under
this Agreement is intended to implement the parties' original understanding
concerning the ARCOS-1 cable.

2.   Capacity on Americas III Undersea Cable. Genuity is currently participating
     ---------------------------------------
in the negotiations of the Americas III Cable Network Construction and
Maintenance Agreement (C&MA). Upon substantial completion of the C&MA, Genuity
and Bell Atlantic will discuss the options associated with obtaining capacity on
Americas III, including whether one will sell or assign Americas III capacity to
the other. Alternatively, each may sign the C&MA independently.

3.   Provisions Applicable to Undersea Cable Capacity. Sections 2, 4, 6, 9, 10,
     ------------------------------------------------
13 and 14 of the Agreement apply to the Provision of such undersea capacity
Services as set out in this Service Schedule. The remaining provisions of the
Agreement are superseded by this Service Schedule and by the terms of the
applicable agreement governing the ARCOS-1 or Americas III cable. Payments for
such undersea capacity Services do not apply toward the Purchase Commitment as
described in Section 7.3 of the Agreement.
