ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

     Our Restated Certificate of Incorporation will provide for the
indemnification of directors to the fullest extent permissible under Delaware
law.

     Our Bylaws will provide for the indemnification of officers, directors and
third parties acting on our behalf if such person acted in good faith and in a
manner reasonably believed to be in and not opposed to the best interest of ATG,
and, with respect to any criminal action or proceeding, the indemnified party
had no reason to believe his or her conduct was unlawful.

     We have entered into indemnification agreements with our directors and
executive officers, in addition to indemnification provided for in our Bylaws,
and intend to enter into indemnification agreements with any new directors and
executive officers in the future.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

     During the past three years, we have issued unregistered securities to a
limited number of persons as described below.

     - From December 1999 through April 2000, we sold an aggregate of 39,428,471
       shares of Series D Preferred Stock to private investors at a purchase
       price of $4.44 per share for an aggregate purchase price of
       $175,062,411.20.

     - In connection with our acquisition of NewComm Net, Inc., in September
       1999, we issued 1,250,456 shares of our common stock to certain
       shareholders of NewComm Net, Inc. in exchange for their shares of NewComm
       Net, Inc.

                                      II-1
<PAGE>   3

     - From August 1999 through December 1999, we sold an aggregate of 1,503,880
       shares of Series C Preferred Stock for $1.852 per share to private
       investors for an aggregate purchase price of $2,784,964.70.

     - From November 1998 through December 1999, we sold 67,500,000 shares of
       Series B Preferred Stock for $1.482 per share to private investors for an
       aggregate purchase price of $100,000,035.00.

     - In July 1998, we sold 1,350,000 shares of Series A Preferred Stock for
       $1.482 per share to private investors for an aggregate purchase price of
       $2,000,000.00.

     - In July 1998, we sold 3,650,050 shares of our common stock to certain of
       our officers for an aggregate purchase price of $233,600.

     - In April 2000, we issued 171,900 shares of our common stock in our
       acquisition of all of the outstanding shares of Olympia Networking
       Services, Inc.

     None of the foregoing transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and we believe that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule
701 pursuant to compensatory benefit plans and contracts relating to
compensation as provided under such Rule 701. The recipients in such transaction
represented their intention to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof, and
appropriate legends were affixed to the share certificates and instruments
issued in such transactions. All recipients had adequate access, through their
relationships with us to information about us.

(b) FINANCIAL STATEMENT SCHEDULES

     Schedules have not been provided because the information required to be set
forth therein is not applicable or is shown in the financial statements or notes
thereto.

ITEM 17.  UNDERTAKINGS

     ATG hereby undertakes to provide to the Underwriters at the closing
specified in the Underwriting Agreement certificates in such denominations and
registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.

     Insofar as indemnification by ATG for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of ATG pursuant to the provisions referenced in Item 14 of this Registration
Statement or otherwise, ATG has been advised that in the opinion of the
Securities and
                                      II-3
<PAGE>   5

Exchange Commission such indemnification is against public policy as expressed
in the Securities Act, and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
ATG of expenses incurred or paid by a director, officer, or controlling person
of ATG in the successful defense of any action, suit or proceeding) is asserted
by a director, officer or controlling person in connection with the securities
being registered hereunder, ATG will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     ATG hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act, the
         information omitted from the form of Prospectus filed as part of this
         Registration Statement in reliance upon Rule 430A and contained in a
         form of Prospectus filed by ATG pursuant to Rule 424(b)(1) or (4) or
         497(h) under the Securities Act shall be deemed to be part of this
         Registration Statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities Act,
         each post-effective amendment that contains a form of Prospectus shall
         be deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time shall
         be deemed to be the initial bona fide offering thereof.

                           CARRIER SERVICE AGREEMENT

THIS CARRIER SERVICE AGREEMENT (the "Agreement") is entered into by and between
Qwest Communications Corporation ("Qwest") located at 4250 North Fairfax Drive,
Arlington, Virginia 22203, facsimile number (703) 363-3750 and Shared
Communications Services, Inc. (the "Customer") located at 3723 Fairview
Industrial Drive, S.E., Salem, Oregon 97302, facsimile number (503) 316-4467.
Qwest and Customer are sometimes referred to in this Agreement collectively as
the Parties and singularly as a "Party".

TERMS AND CONDITIONS

1.   SCOPE OF AGREEMENT

     Qwest agrees to provide and Customer agrees to purchase Qwest service(s)
     for the price(s) and subject to the terms and conditions set forth herein
     described in the exhibits attached hereto (the "Service" or "Services").
     All Service is provided pursuant to Qwest/LCI Tariff F.C.C. No. 1,
     Qwest/LCI Tariff F.C.C. No. 2 and applicable state tariffs (collectively,
     the "Tariff(s)"), which are on file with the Federal Communications
     Commission ("FCC") and applicable state regulatory bodies. The Tariffs may
     be modified from time to time by Qwest in accordance with law and thereby
     affect the Service(s) furnished Customer. To the extent applicable to the
     furnishing of Qwest Services hereunder, the Tariff, as amended from time to
     time, is hereby incorporated herein and made a part hereof, except that the
     following terms and conditions shall supplement or, to the extent
     inconsistent, supersede Tariff terms and conditions and shall remain in
     effect throughout the service term; as hereinafter defined.

2.   MONTHLY MINIMUM COMMITMENT

     (A)  Any monthly minimum usage commitments agreed upon by Qwest and
     Customer shall be set forth in the attached Services Descriptions and rate
     Exhibits, which such exhibits are specified in Section 3 of this Agreement
     (the "Monthly Commitment"). Customer acknowledges and agrees that certain
     rates and discounts may be being provided to Customer hereunder in
     consideration of Customer's agreement to meet or exceed the Monthly
     Commitment and that such rates and discounts would not be offered to
     Customer without Customer's agreement to make such commitments.

     (B)  The minimum monthly usage required per DS-1 is [*] MOUs averaged
     among all Qwest DS-1s used by Customer under this Agreement (the "Minimum
     Facility Utilization"). In the event Customer fails to meet or exceed the
     Minimum Facility Utilization average, Qwest shall give Customer five (5)
     business days notice of the certain circuits that are not meeting such
     commitment. Customer agrees, within such five (5) day period, either to (i)
     bring usage up to such Minimum Facility Utilization average on such
     circuits or (ii) release such circuits under the [*] to Qwest from use
     by Customer. If Customer does not comply with the above requirement,
     Customer will be assessed a monthly underutilization fee of [*] (the
     "Underutilization Fee") for each DS-1 which was under the Minimum Facility
     Utilization for such month.

     (C)  Qwest and Customer specifically agree that any underutilization fees,
     deficiency charges or other relief, if any, provided for in this Agreement
     or the Exhibits relating to any of the commitments in this Agreement or the
     Exhibits represent mutual good faith estimates of, and bear reasonable
     relationships to, the actual damages to Qwest in the event of Customer's
     failure to meet such commitments or Customer's underutilization of such
     circuits, and they do not represent a penalty of any kind. The Parties
     further agree that such fees, charges and relief are obligations of
     Customer, subject to specific performance.

          Customer as follows:

          a)   Rate decreases and additional services offered, if any, in

               part, in the event of any material increase in rates for

                           CARRIER SERVICE AGREEMENT

4.    SYSTEM MAINTENANCE

      Subject to Sections 7 and 12 hereof, Qwest expects, but does not
      guarantee, that system maintenance normally will not result in service
      interruptions. If system maintenance should result in the interruption of
      Service, to the extent possible it shall be accomplished only after prior
      notification to Customer and will be completed within a reasonable time.

5.    CUSTOMER SERVICE

      Customer acknowledges and agrees that it shall provide all billing,
      inquiry, and customer service to Customer's end-users or customers (the
      "End-Users").

6.    REPRESENTATION

      Customer shall not use any trademark, service mark, brand name or any
      other intellectual property of Qwest or any Qwest affiliate without
      Qwest's prior express written consent. Notwithstanding the foregoing,
      Customer may disclose, during pre-sale activities, that Qwest is the
      underlying carrier of its service. In no event shall Customer represent
      or state to End Users or prospective End Users that it has any
      relationship with Qwest other than an agreement to purchase Qwest's
      services. Customer shall promptly and fully cooperate with Qwest to
      address and resolve all issues, problems, administrative procedures, End
      User complaints, regulatory investigations or inquiries or any other
      circumstances arising from Customer's use of Qwest Services.

7.    FINANCIAL RESPONSIBILITY, PAYMENT AND SECURITY

      (A)   Qwest shall use commercially reasonable efforts to provide accurate
      billing and call detail records to Customer in accordance with Qwest's
      then standard formats. Customer shall pay all Qwest invoices for Service
      within thirty (30) calendar days from invoice date via cash, check or
      wire transfer. All discounts and promotions, if any, and taxes, will be
      included in the monthly invoice. Any payment received by Qwest later than
      thirty (30) calendar days after the due date of the invoice shall be
      subject to an interest charge on delinquent amounts at the rate of [*]
      of the late payment per month or the maximum lawful rate allowable under
      applicable state law, whichever is lower. Such interest charge shall be
      applied on any late payments, commencing upon the invoice due date
      through the actual date of receipt of payment. Any applicable federal,
      state or local use, excise, sales or privilege taxes, duties or similar
      liabilities, chargeable to or against Qwest because of the Service
      provided Customer shall also be charged to and payable by Customer. If
      full payment is not made when due, Qwest, in its sole discretion, shall
      have the right, after Qwest has given written notice to Customer, to
      suspend all or any part of the Service until such time as Customer has
      paid all unpaid balances (including interest), or to terminate all or any
      part of the Service. During any such suspension, and upon any such
      termination, no service interruption shall be deemed to occur.

      (B)   Customer acknowledges that it may not withhold any sums invoiced by
      Qwest for actual calls made by Customer including, without limitation,
      calls made by Customer's End Users and/or unauthorized third parties
      (e.g., fraudulent calls) and charges to Customer's Qwest account(s).
      Customer will be responsible for full payment of all charges as reflected
      on any Qwest billing statement. Independent of Customer's payment
      obligations set forth in this section, Customer must notify Qwest within
      sixty (60) calendar days of receipt of any contested or disputed amount
      concerning charges as they appear on the Qwest billing statement.
      Customer's notification of any contested or disputed amount must be in
      writing and sent to: Credit & Collections Department, Qwest
      Communications Corporation, 4650 Lakehurst Court, Dublin, Ohio 43017 or
      to (614) 798-6460, by facsimile with duplicate notification to follow via
      regular U.S. Mail or overnight delivery. Written notification must be
      accompanied with a detailed written support, for any service interruption
      credit or other credit to which Customer believes itself

     entitled, and Qwest and Customer will promptly address and attempt to
     resolve the claim. Qwest, in its sole discretion exercised in good faith,
     may reject such documentation and/or explanation as inadequate. If Qwest so
     rejects such documentation, Customer shall have an additional ten (10)
     business days to provide additional supporting documentation to Qwest. If
     Qwest rejects such additional documentation, Qwest shall so notify Customer
     in which case the disputed portion of the bill shall be paid by Customer
     within ten (10) business days of Customer's receipt of Qwest's final notice
     of inadequacy. All Credits or adjustments for service outages will be made
     pursuant to applicable provisions of Qwest/LCI's Tariff F.C.C. No. 1 and
     Tariff F.C.C. No. 2 and applicable state tariffs which are on file with the
     Federal Communications Commission and applicable state regulatory bodies
     and which may be modified from time to time by Qwest in accordance with
     law. In consideration of the discounts offered by Qwest pursuant to this
     Agreement, with respect to any unpaid balance(s) owed by Customer to Qwest,
     Qwest shall have the right to offset such unpaid balance(s) from any
     amounts that Qwest owes to Customer and any of its affiliates.

     (C) Customer acknowledges and agrees that Qwest may reasonably require
     additional security and/or payment terms under this Agreement prior to the
     commencement of Services hereunder, and Customer agrees to comply with
     such request. Customer agrees to provide and/or execute any additional
     collateral security documents, including, without limitation, an
     irrevocable letter of credit, a cash deposit, a prepaid invoice amount, a
     corporate guarantee, as may be reasonably required by Qwest, in Qwest's
     sole judgment, if there is a material change in circumstances of
     Customer's actual or anticipated usage hereunder or Customer's financial
     condition during any time that Customer uses the Service.

8.   TERM

     The initial term of this Agreement (the "Initial Term") will begin on the
     first day of the first billing cycle following the Effective Date (as
     hereinafter defined) of this Agreement (the "Initial Service Date") and
     will continue for a period of the longer of (i) twelve (12) calendar
     months from the Initial Service Date, or (ii) as long as a term for a
     Service attached to this Agreement (the "Service Term") is in effect;
     provided, however, that, following Customer's execution of this Agreement,
     Qwest shall execute this Agreement as soon as possible but in no event
     later than thirty (30) calendar days after Customer's execution date. The
     "Effective Date" is defined as the date this Agreement is signed by an
     authorized officer of Qwest after having been signed by Customer.
     Applicable Service rates and discounts, if any, shall be effective as of
     their respective effective date in the applicable Service rate or discount
     schedule. Following the Initial Term, the Agreement shall continue on a
     monthly basis (each a "Renewal Term") until either party provides the
     other party with at least thirty (30) calendar days prior written notice
     of its intent to terminate this Agreement and the intended date of such
     termination. The Initial Term and Renewal Terms are sometimes collectively
     referred to herein as the "Term".

9.   OBLIGATIONS UPON EXPIRATION OR TERMINATION OF TERM

     Upon expiration or termination of this Agreement, Customer shall pay all
     outstanding balances in accordance with Section 7 of this Agreement. Upon
     expiration or termination of this Agreement, Customer shall be fully
     subject to all terms and conditions, including standard tariffed rates,
     set forth in the Qwest/LCI Tariff for Qwest services received by Customer
     after such date.

          the subject of service outages or interruptions accumulating 120 hours
          or more over any period of 180 consecutive calendar days.

     (B)  Either party may terminate this Agreement without liability or further
          obligation, except for unpaid charges as of the effective date of such
          termination, if Qwest is prohibited from furnishing the Service or if
          any material rate or term contained herein is substantially changed by
          order of the highest court of competent jurisdiction to which the
          matter is appealed, the FCC, or any other federal, state or local
          government authority.

     (C)  In addition, Customer represents, warrants and covenants that it
          understands that Qwest may, at any time, and without notice to End
          User(s), discontinue providing service to Customer in accordance with
          the terms of the Qwest/LCI Tariff and that such discontinuance may
          result in termination of service to the End User(s).

     (D)  Notwithstanding the foregoing, and without affecting Qwest's right to
          compensation accrued prior to the termination date, Qwest, without
          waiving any rights set forth in this Agreement or the Qwest/LCI
          Tariff, retains the right to terminate this Agreement immediately and
          without written notice, under any of the following circumstances:

          (i)   Customer becomes or is declared insolvent or bankrupt, is the
                subject of any proceedings related to its liquidation,
                insolvency or for the appointment of a receiver or similar
                officer for it, makes an assignment for the benefit of all or
                substantially all of its creditors, or enters into an agreement
                for the composition, extension, or readjustment of all or
                substantially all of its obligations;

          (ii)  Material change in Customer's ownership, except as otherwise
                permitted; provided, however, that consent by Qwest to the
                assignment of this Agreement after such change in ownership
                shall not be unreasonably withheld; or

          (iii) Customer's failure to abide by all terms of Section 7 hereof,
                including, without limitation, Customer's failure or refusal to
                provide additional security or payment upon Qwest's request, or
                for any unethical or illegal acts on the part of Customer, its
                officers, directors, employees, contractors, agents, or
                servants, relating to the subject matter of this Agreement.
                Termination of this Agreement shall not affect Qwest's right to
                compensation accrued prior to the termination date; or

          (iv)  for any material breach of this Agreement.

     (E)  Customer shall be entitled to terminate this Agreement in whole or in
          part, in the event of a material breach by Qwest of its obligations
          under this Agreement, including without limitation, the provision of
          accurate billing detail to Customer.

11.  Default

     Without regard to any other provisions of this Agreement or rights
     hereunder, it shall be a default under this Agreement, if Customer fails to
     pay Qwest in accordance with Section 7 of this Agreement; provided,
     however, that Qwest has provided accurate billing detail to Customer.

     transfer of this Agreement by Customer without Qwest's prior written
     consent.

15.  REPORTING REQUIREMENTS

     Where reporting obligations or requirements are imposed upon Qwest by any
     third party or regulatory agency that are in accordance with the reporting
     requirements for Customers and Carriers in the telecommunication industry,
     Customer agrees to comply with such requirements and obligations and to
     hold Qwest harmless for any failure of compliance with any such requirement
     or obligation.

16.  GOVERNING LAW, CERTIFICATIONS AND WARRANTIES

     (A)  Customer understands that Qwest, in conducting its business in the
          manner set forth herein, is subject to the Communications Act of
          1934, as amended, and as interpreted and applied by the Federal
          Communications Commission. All terms of this Agreement not subject to
          the Communications Act of 1934 as amended and as interpreted and
          applied by the F.C.C. will be interpreted according to New York state
          law.

     (B)  If service is provided solely within a single state in a manner which
          subjects the Service to regulation by such state, then the terms and
          conditions of such Service and of this Agreement shall be subject to
          such regulations and to any addendum to this Agreement relating
          thereto which is delivered by Qwest to Customer. Customer shall have
          the right to terminate this Agreement within ten (10) business days
          of receipt of such addendum without further liability hereunder.

     (C)  Customer certifies and warrants that it is in compliance with and
          will continue to be in compliance with all international, federal,
          state and local laws and regulations relating to its performance
          under this Agreement. Customer is solely responsible for obtaining
          all licenses, approvals, and regulatory authority for its operation
          and the provision of services to its customers ("End Users"). Any
          breach of the obligations of Customer under this Section shall be a
          material breach of this Agreement. If Customer does not comply with
          this Section, in addition to any remedies available to Qwest at law
          or in equity, Qwest, in its sole discretion, may elect to decline to
          accept additional orders under this Agreement or may immediately
          terminate this Agreement without further liability or obligation to
          Customer.

17.  TERMS AND CONDITIONS SURVIVING TERMINATION OR EXPIRATION OF AGREEMENT

     All warranties, representations, indemnities, covenants and other
     agreements of the parties hereto shall survive the execution, delivery and
     termination of this Agreement and shall, notwithstanding the execution,
     delivery and termination of this Agreement, continue in full force and
     effect. The terms and conditions of the Qwest/LCI Tariff along with
     Section 6, 7, 9, 11, 12, 13, 15, 18, 23, 24 and any provision hereof,
     which, by its context is intended to survive the termination or expiration
     hereof, shall also survive. Additionally, any obligation to hold harmless
     and indemnify a party hereunder shall survive the termination or
     expiration of this Agreement.

18.  INDEMNIFICATION

     Customer shall indemnify, defend and hold harmless Qwest from and against
     any claims, actions, damages, liabilities, costs, judgments or expenses
     (including attorney fees) arising out of (i) the


                       QWEST CONFIDENTIAL AND PROPRIETARY

     resale or reselling of the Service, including but not limited to the
     provision or termination of service by Customer to End Users and any
     failure to provide service; and (ii) any breach by Customer of any
     warranty, representation, or covenant hereunder.

19.  NONDISCLOSURE

     Neither Party shall disclose to any third party during the term of this
     Agreement and during the two (2) year period immediately following
     termination of this Agreement, any of the terms and conditions set forth in
     this Agreement unless disclosure is required by any state or federal
     governmental agency, is otherwise required to be disclosed by law, or is
     necessary in any proceeding establishing rights or obligations under this
     Agreement. Each Party reserves the right to terminate this Agreement, upon
     written notification, upon discovery of any disclosure prohibited
     hereunder.

20.  AMENDMENTS

     The Agreement, together with all Exhibits, represents the entire
     understanding of the parties. Any and all prior offers, agreements,
     representations and understandings made to Customer, whether oral or
     written, shall be superseded by this Agreement. Exclusive of any Tariff
     modifications initiated by Qwest, once this Agreement has been fully
     executed, any amendment hereto must be made in writing and signed by
     authorized representatives of both parties.

21.  WAIVER

     The terms, covenants, representations and warranties of this Agreement may
     be waived only by a written instrument executed by the party waiving
     compliance. The failure of either party at any time to require performance
     of any provision hereof shall, in no manner, affect the right at a later
     date to enforce the same. No waiver by either party of any breach of any
     term, covenant, representation or warranty contained in this Agreement,
     whether by conduct or otherwise, in any one or more instances, shall be
     deemed to be construed as a further or continuing waiver of any such breach
     or the breach of any other term, covenant, representation or warranty of
     this Agreement.

22.  SEVERABILITY

     In the event that any one or more of the provisions contained in this
     Agreement shall for any reason be held to be invalid, illegal or
     unenforceable in any respect, such invalidity, illegality or
     unenforceability shall not affect any other provision of this Agreement,
     but this Agreement shall be construed as if such invalid, illegal or
     unenforceable provision had never been contained herein. Further, in the
     event that any provision of this Agreement shall be held to be invalid,
     illegal or unenforceable by virtue of its scope or period of time, but may
     be made enforceable by a limitation thereof, such provision shall be deemed
     to be amended to the minimum extent necessary to render it valid, legal
     and enforceable or in the alternative both parties shall negotiate in good
     faith to substitute for such invalid, illegal, or unenforceable provision
     a mutually acceptable provision that is consistent with the original
     intent of the parties.

     that a P.O. Box shall not be considered to be an address for purposes of
     this Agreement.

24.  ARBITRATION OF DISPUTES

     (A)  Any dispute arising out of this Agreement relating to Qwest invoices
          or balances owed by Customer to Qwest for Services rendered, which
          cannot be resolved between the parties, shall be settled by binding
          arbitration at the office of the American Arbitration Association
          ("AAA") located in Washington, D.C or Denver, Colorado, as the choice
          of the Party bringing the arbitration. The arbitration shall be held
          in accordance with the commercial Arbitration Rules of the American
          Arbitration Association ("AAA Rules"), as amended by this Agreement.
          Neither party may seek injunctive relief of any kind prior to the
          confirmation of an arbitration award.

     (B)  Either Qwest or the Customer may initiate arbitration by providing
          written demand for arbitration, a copy of this Agreement and the
          administrative fee required by the AAA Rules to the AAA at its
          Washington, D.C. or Denver office, as applicable. A copy of the
          notice shall also be provided to the other party. The remaining cost
          of the arbitration, including the fees and expenses of the
          arbitrator, shall be shared equally by the parties unless the
          arbitration award provides otherwise. Each party shall bear the cost
          of preparing and presenting its case.

     (C)  One Arbitrator shall be appointed in accordance with the AAA Rules
          within sixty (60) days of the submission of the demand for
          arbitration, unless both parties otherwise agree in writing. The
          Arbitrator shall designate the time and place in the Washington, DC
          area for the hearing within thirty (30) days of his or her
          appointment. Qwest and the Customer

                  agree that the Arbitrator's authority to grant relief shall
                  be subject to the provisions of this Agreement, the United

                  for Arbitrators in Commercial Disputes Qwest/LCI Tariffs,
                  substantive law, and the Communications Act of 1934, as
                  amended. The Arbitrator shall not be able to award, nor shall
                  any party be entitled to receive punitive, incidental,
                  consequential, exemplary, reliance or special damages,
                  including damages for lost profits. The Arbitrator's decision
                  shall follow the plain meaning of the relevant documents, and
                  shall be final, binding, and enforceable in a court of
                  competent jurisdiction. The decision of the Arbitrator is
                  appealable only for perceived mistakes or misapplication of
                  the law.

            (D)   Any dispute not outlined in Section 24(A) and arising out of
                  or related to this Agreement regardless of the form of action
                  whether in contract, indemnity, warranty, strict liability,
                  or tort, including negligence of any kind with regard to
                  Qwest Services or other conduct under this Agreement may be

              QWEST EXPRESS RBOC/ITC TERMINATING SWITCHED SERVICE
                           CARRIER SERVICES AGREEMENT

GENERAL

Interstate rates are per Local Access and Transport Area ("LATA") and are for
LATA-wide termination. Regional Bell Operating Company ("RBOC") rates apply to
all traffic terminating in RBOC territories, and independent telephone company
("ITC") rates, or Non-Bell rates, apply to all traffic terminating in ITC
("Non-RBOC") territories. For the purposes of billing the appropriate
territory, the OCN number of the terminating carrier will be used. OCN numbers
of 9000 and above shall be classified as RBOC; and OCN numbers less than 9000
shall be classified as "ITC", or Non-RBOC.

Intrastate rates are per State and are for State-wide termination. For the
purposes of determining each call's jurisdiction, the originating and
terminating information present in the call stream will be evaluated. In the
event that either the originating or terminating information is not available
to Qwest's billing system, the classification of the call, for rating purposes,
will default to the Interstate classification. To the extent that calls are
defaulted to the Interstate classification, and to the extent Customer's
traffic of this nature includes intrastate traffic, Customer shall provide to
Qwest in writing, on a monthly basis, the "Percentage of Inter/Intra-state
Usage" on a state-by-state basis, by LEC, for the traffic terminated by Qwest
hereunder.

Rates shown in the Qwest Express RBOC/ITC Interstate and Intrastate Rate
Exhibits are shown in terms of full minutes and are billed in [*] second
increments. Qwest reserves the right to charge excessive quantities of short
duration calls (i.e., calls under [*] in length) [*]. Rates shown in the Qwest
Express RBOC/ITC Interstate and Intrastate Rate Exhibits are Base Rates.
Discounts, if any; pursuant to the below Discounts Section and Discount
Schedule.

ROUNDING

Currently, the Qwest Express RBOC/ITC Terminating Switched Service utilizes
"bulk rounding". For the purposes of this agreement, bulk rounding is defined as
carrying over the 3rd and 4th place amounts of a call charge to the next call,
and continuing to do so until one full cent ($.01) is accrued. When this has
occurred, the cent is applied to the next call. In addition, the Qwest Express
RBOC/ITC Terminating Switched Service employs [*], which means that all calls
are [*], as opposed to [*] (e.g. initial and incremental).

terms of full minutes and are billed in [*] second increments. All answered
calls will be billed a minimum of [*].

ROUNDING

The Qwest Express 8XX Originating Service utilizes "bulk rounding". For the
purposes of this agreement, bulk rounding is defined as carrying over the 3rd
and 4th place amounts of a call charge to the next call, and continuing to do so
until one full cent ($.01) is accrued. When this has occurred, the cent is
applied to the next call. In addition, the Qwest Express 8XX Originating Service

and incremental).

charges. Qwest will have the right to apply a [*] per minute of use surcharge to
the number of minutes by which Non-RBOC Originating minutes exceed [*] of total
monthly Origination service minutes. for the purposes of automating the billing
of the surcharge, the OCN number of the originating carrier will be used. OCN
numbers of 9000 and above are classified as RBOC; and OCN numbers less than 9000
are classified as "ITC", or Non-RBOC.

QWEST AS RESPONSIBLE ORGANIZATION ("RESP ORG")

     (A)  Qwest agrees to act as RESP ORG, to manage and administer Customer's
          records in the 8XX Service Management System. Qwest's responsibilities

          sectionalizing trouble to determine if the reported trouble is in its
          translations or facilities or in another provider's service. If
          necessary, Qwest will test cooperatively with other providers to
          further identify and address a trouble when it has been sectionalized
          to another provider's service. Qwest will keep Customer advised as to
          the status of trouble clearance. Qwest's responsibilities shall be
          limited to make a good faith effort to identify and coordinate trouble

             QWEST EXPRESS CANADIAN TERMINATING SERVICE DESCRIPTION
                          WHOLESALE SERVICES AGREEMENT

GENERAL

Carrier Canadian Terminating Service rates are per NPA and are for NPA-wide
termination. Rates shown in the Carrier Canadian Terminating Service Rate
Exhibit are shown in terms of full minutes and are billed in [*] increments with
an initial [*] increment. Carrier Canadian Terminating Service is available with
the following Qwest services: Qwest Express Domestic Terminating Service and
Qwest Express: RBOC-ITC Terminating Service. Rate period is determined using
standard Qwest holidays and rate periods. Qwest reserves the right to charge
excessive quantities of short duration calls (i.e. calls [*] in length) a
minimum of [*] per answered call. Rates are subject to change upon five (5)
calendar days prior written notice. Service availability is subject to the
availability of facilities to and in Canada.

ROUNDING

Canadian Terminating Service utilizes "bulk rounding". For the purposes of this
Agreement, bulk rounding is defined as carrying over the 3rd and 4th place
amounts of a call charge to the next call, and continuing to do so until one
full U.S. cent (U.S. $.01) is accrued. When this has occurred, the cent is
applied to the next call. In addition, the Canadian Terminating Service employs
[*], which means that all calls are [*], as opposed to [*] (e.g, initial and
incremental).

           QWEST EXPRESS INTERNATIONAL TERMINATING SERVICE DESCRIPTION
                          WHOLESALE SERVICES AGREEMENT

GENERAL

International rates are per country and are for country-wide termination. Rates
shown in the Carrier International Termination Rate Exhibit are shown in terms
of full minutes and are billed in [*] increments with an initial [*] increment.
Carrier International Terminating Service is available with the following Qwest
services: Qwest Express Domestic Terminating Service and Qwest Express: RBOC-ITC
Terminating Rate period is determined using standard Qwest holidays and rate
periods. Qwest reserves the right to charge excessive quantities of short
duration calls (i.e. calls under [*] in length) a minimum of [*] per answered
call. Service is subject to the availability of facilities to the particular
countries.

ROUNDING

Currently, International Terminating Service utilizes "bulk rounding". For the
purposes of this Agreement, bulk rounding is defined as carrying over the 3(rd)
and 4(th) place amounts of a call charge to the next call, and continuing to do
so until one full cent ($.01) is accrued. When this has occurred, the cent is
applied to the next call. In addition, the International Terminating Service
employs [*], which means that all calls are [*], as opposed to [*] (e.g. initial
and incremental).

                  AMENDMENT NO. 2 TO MASTER CARRIER AGREEMENT


The following is Amendment No. 2 to the Master Carrier Agreement effective
Sept. 15, 1997 ("Agreement") between BellSouth Long Distance, Inc. ("BSLD") and
Shared Communication Services, Inc. ("CUSTOMER"). The Parties further agree
that all terms and conditions of the Master Carrier Agreement shall remain
unchanged, except as amended herein, and that this Amendment is incorporated
into the Master Carrier Agreement.

1.   The following paragraphs are hereby added to the Agreement and are fully
     incorporated therein by this reference:

     13.3 Noncomplete Call Surcharge. Any month Customer exceeds the Maximum
          Noncomplete Toll Free Call Percentage for interstate Dedicated Toll
          Free, and/or interstate Switched Toll Free traffic as stated on
          Exhibit 4, Customer shall pay BSLD a surcharge equal to the amount
          state in Exhibit 4 for each Noncomplete Toll Free Call in excess of
          the Maximum Noncomplete Toll Free Call Percentage. This surcharge
          shall be calculated at each Subinvoice Hierarchy Level.

     13.5 Other Surcharges. BSLD may include in charges to Customer certain
          charges and surcharges newly imposed after the execution date that are
          levied upon and paid by BSLD with respect to the services. To be
          eligible, or inclusion under this Section, the charges or surcharges
          must be imposed by a governmental authority that is imposing the
          charges or surcharges specifically on telecommunications services, and
          the governing law must not prohibit BSLD from passing the charges or
          surcharges to Customer.

     13.6 Forward Pricing. As a transition to the pricing hereunder, discounts
          may be based for a period of time on the greater of Customer's actual
          Discount Monthly Volume of Service or a specified Forward Pricing
          Volume of Service. The Forward Pricing Volume of Service and the
          period during which it may be applied are specified in Exhibit 3.

     33.  Fraud. Customer is responsible and liable for all fraud incidents,
          maintenance and management, unless caused by BSLD network personnel or
          facilities.

     34.  Responsible Organization. BSLD will be the Responsible Organization,
          (Resp. Org.), for Toll Free services provided under this Agreement and
          will be designated as the Resp. Org. in the SMS Database.

2.   The following definitions are hereby added to Exhibit 1 to the Agreement,
     DEFINITIONS, and are fully incorporated therein by this reference:

     "BELLSOUTH NINE STATE REGION" consists of the following states: Alabama,
     Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South
     Carolina, and Tennessee.

     "MAXIMUM NONCOMPLETE TOLL FREE CALL PERCENTAGE" means, for each month, for
     each Service type, the ratio, expressed as a percentage, of (i) the
     aggregate number of Noncomplete Toll Free Calls during such period divided
     by (ii) the aggregate number of Toll Free calls during such period. This
     percentage shall be calculated at each Subinvoice Hierarchy Level.

     "PAYPHONE SURCHARGE" means compensation to payphone service providers for
     all non-coin calls completed from their payphones on a per call basis. This
     compensation will be paid by the carriers that transport these calls and
     then passed through to the Toll Free customers. Any interstate calls from
     payphones, including remote access and calling card calls will incur this
     per call charge.

     to provide said Services. Accordingly, BSLD will not offer any Services
     that originate or terminate, or both, in any of BellSouth's Nine State
     Region prior to receiving full legal authority, including authority
     granted under 47 U.S.C. 271 (d)(3) to offer in a state non-incidental

Agreement are offered subject to the availability of the service components

by law, regulation or the Commission to disclose such identity. Absent such a
filing requirement, neither party shall disclose the terms or conditions of this
Agreement to any third party, nor issue any public statements relating to this
Agreement without the written consent of the other party, unless such disclosure

authority. A disclosing party shall furnish reasonable prior notice to the other
party before making the statement or disclosure unless prohibited by law from
doing so.

3.2  Each party shall preserve CONFIDENTIAL INFORMATION received from the other

INFORMATION that constitutes a trade secret shall be held in confidence in
perpetuity. The receiving party shall restrict disclosure of such CONFIDENTIAL
INFORMATION solely to its employees and employees of its affiliated companies

   party shall first give the other party reasonable notice and opportunity to
   object to the order or request and/or to obtain a protective order covering
   the CONFIDENTIAL INFORMATION to be disclosed; or

- -  approved for release by written authorization of the disclosing party.

3.5  Either party may disclose CONFIDENTIAL INFORMATION to a person (other than

connection with this Agreement or the service provided hereunder

INFORMATION provides to the other party a copy of a written agreement by such
Consultant (i) to use such CONFIDENTIAL INFORMATION only for he purpose of
providing such services to the disclosing party, and (ii) to be bound by the
obligations of a receiving party under this Agreement with respect to such

CONFIDENTIAL INFORMATION received from the other party and shall use best

then in its possession or control, promptly furnishing the originating party
with written certification of such destruction. Alternatively, at the request
of the originating party, the receiving party shall use best efforts to return
all such CONFIDENTIAL INFORMATION and copies to the originating party; provided
that CONFIDENTIAL INFORMATION contained in BSLD databases and/or mechanized

terms of this Section, the non-breaching party shall be entitled to seek an
injunction prohibiting or halting any such breach. Any such relief shall be in
addition to and not in lieu of any appropriate relief in the way of money
damages. The parties acknowledge that the CONFIDENTIAL INFORMATION is valuable
and unique, and that disclosure in breach of this will result in irreparable
injury to the originating party.

such loss, and not as a penalty. Customer shall pay BSLD an EARLY TERMINATION
CHARGE in the event of such termination. The EARLY TERMINATION CHARGE shall

partner, agent or fiduciary of Customer. The relationship established by this
Agreement shall in no way constitute Customer (or its agents or employees) as a

agreement does not establish any joint undertaking, joint venture, ??????
arrangement, partnership, agency, fiduciary relationship or formal business
organization of any kind. Customer and BSLD shall be independent

shall act as or hold itself out as agent for the other or create or attempt to
create liabilities for the other party.

Customer nor BSLD shall use the other's trade names, trademarks or service marks
("Marks") without the prior written approval of the other party. Neither shall
display or use the other's Marks, nor permit the same to be displayed or used by
third parties. Nothing in this Agreement creates in a party rights in the marks
of the other. In the event that Customer resells the Service provided hereunder,
it will do so only under its own names, trade names, logos, trademarks or
service marks. Customer will not publish or use any advertising, sales
promotions, press release, or other publicity matters which use BSLD's corporate
or trade names, logos trademarks, serve marks, trade dress, or other symbols
that serve to identify and distinguish BSLD from its competitors (or which use
confusingly similar corporate or trade names, logos, trademarks, service marks,
trade dress or other symbols), and will not conduct business under BSLD's
corporate or trade names, logos, trademarks, service marks, trade dress, or
other symbols that serve to identify and distinguish BSLD from its competitors
(or under any confusingly similar corporate or trade names, logos, trademarks,
service marks, trade dress or other symbols). Customer (including its agents,
representatives and independent contractors) will not indicate or imply to any
person or entity that it is BSLD which is selling or providing service to
Customer's end-users, or that it is affiliated or authorized by BSLD to sell or
provide such service to them or that it is selling or providing such service to
them jointly or in collaboration or partnership with BSLD, or as the agent of
BSLD. BSLD shall provide Customer written notice of a breach of this paragraph.
Customer shall use its best efforts to immediately cure such breach advising
BSLD of its actions. If, in BSLD's opinion, Customer fails to effect a cure
within 30 days of BSLD's notice, then BSLD may, at its option, terminate the
Agreement pursuant to Subparagraph 5.2.

9.   LEGAL COMPLIANCE: REMEDIES FOR NON-COMPLIANCE.

9.1.      Each party is responsible for its own compliance with all laws and
regulations affecting its business, including but not limited to the collection
and remittance of all taxes and other levies imposed by law. Customer certifies
that it has obtained the required operating authority in all states in which it
conducts business, as well as all authority required by the FCC for resale of
telecommunications services, including but not limited to authority required
pursuant to Section 214 of the Communications Act of 1934, 47 U.S.C. Section
214, and that it complies and will continue to comply at all times with all
federal and state laws and regulations applicable to the sale and provision of
service to its customers.

9.2.      If, in BSLD's opinion, Customer breaches this paragraph, BSLD may (a)
terminate this Agreement pursuant to Subparagraph 5.1(e), and/or (b)
discontinue PROMOTIONAL DISCOUNTS. If BSLD elects option (b), it will resume
and/or reinstate PROMOTIONAL DISCOUNTS only after Customer produces evidence
satisfactory to BSLD that it has cured its breach.

     CUSTOMER RESPONSIBILITIES.

10.1.     Customer shall not be relieved of any obligation hereunder by virtue
of the fact that Service is ultimately used by END USERS.

10.2.     Interfacing and communicating with END-USERS shall be the sole
responsibility of Customer with respect to any use that Customer may make of
the service provided pursuant to this Agreement to in turn provide service to
other persons or entities. Customer shall be solely responsible for END USER

systems and support, billing and collection.

END USERS, and billing adjustments it grants END USERS, including adjustments
for fraudulent charges, directory assistance or any other form of credit.

10.4.     Customer shall comply with BSLD's network interface procedures when
it orders its own access facilities.

11.  SERVICE ACTIVATION. BSLD will use reasonable efforts to provide dedicated
SERVICE within thirty (30) days, following Customer's order, or the requested
delivery date, whichever is later. These deadlines will be extended by the time
it takes to address activation errors or obtain from Customer a complete and
accurate order. Customer shall reimburse BSLD for LEC imposed fees resulting
from a request to expedite SERVICE.

12.  PRICING; GENERAL CONDITIONS.

12.1.     Pricing. BASE RATES and PROMOTIONAL DISCOUNTS are contained in the
Exhibits hereto.

12.3.     Prices Contingent on Performance.  BASE RATES and PROMOTIONAL
DISCOUNTS are contingent on Customer's full performance of all terms of the

utilizing the BILLING INCREMENTS in EXHIBIT 4.

12.5. Promotional Pricing Levels. Customer will receive discounts applied only
to RATE ELEMENTS as provided in EXHIBIT 5.

contingent on Customer utilizing BSLD as its PRIMARY CARRIER for the PRIMARY
CARRIER SERVICES listed in EXHIBIT 3. If Dedicated Outbound Services is a

Customer's control shall be placed on the BSLD network during the TERM. Customer
shall produce, within 30 days following BSLD's request, evidence acceptable to
BSLD that it is in compliance with this subparagraph. Failure to maintain BSLD
as PRIMARY CARRIER on any PRIMARY CARRIER SERVICE will result in SERVICE being
provided hereunder at BASE RATES for the remainder of the TERM. Customer may
select a temporary back-up carrier for any period during which it is affected by
a BSLD network outage.

12.7. Pricing Contingent on Tax Compliance. The price of SERVICE is exclusive of
applicable taxes. BASE RATES and PROMOTIONAL DISCOUNTS are contingent on
Customer providing BSLD with certificates from appropriate taxing authorities
exempting Customer from taxes that would otherwise be invoice hereunder.

13.   SURCHARGES.

13.1. Minimum Commitment Surcharge. Any month Customer fails to meet the MINIMUM
USAGE COMMITMENT stated on EXHIBIT 3, Customer shall pay a surcharge for Service
provided during such month equal to [*] of the difference between the MINIMUM
USAGE COMMITMENT and Customer's Net Usage. The MINIMUM COMMITMENT shall not
relieve Customer of any credit or security obligation hereunder.

13.2. Minimum Average Time Requirement Surcharge. Any month Customer fails to

                                  [QWEST LOGO]

                          SWITCHLESS RESELLER AGREEMENT

THIS SWITCHLESS RESELLER AGREEMENT (this "Agreement") is entered into by and
between Qwest Communications Corporation ("Qwest"), with principal offices at
4250 North Fairfax Drive, Arlington, Virginia 22203 and Shared Communications
Services, Inc. (the "Customer"), an authorized and certificated common carrier
subject to the Communications Act of 1934, as amended, with principal offices
at 3723 Fairview Industrial Drive, SE., Salem, Oregon 97302 (Qwest and Customer
are sometimes referred to herein collectively as the Parties and individually
as the Party).

1.      SCOPE OF AGREEMENT

        Qwest will provide to Customer and Customer will purchase from Qwest
        certain Qwest domestic and international long distance services
        described in the Exhibits hereto (the "Service" or "Services") provided
        pursuant to Qwest/LCI Tariff F.C.C. No. 1, Qwest/LCI Tariff F.C.C. No.
        2, and applicable state tariffs (collectively, "Tariff(s)"), which are
        on file with the Federal Communications Commission ("FCC") and
        applicable state regulatory bodies. The Tariffs may be modified from
        time to time by Qwest in accordance with law and thereby affect the
        Service(s) furnished Customer. To the extent applicable to the
        furnishing of Qwest Services hereunder, the Tariff, as amended from time
        to time, is hereby incorporated herein and made a part hereof, except
        that the following terms and conditions shall supplement or, to the
        extent inconsistent, supersede Tariff terms and conditions and shall
        remain in effect throughout the service term, as hereinafter defined.

2.      MONTHLY MINIMUM COMMITMENT

        Along with all other services Customer procures and uses from Qwest,
        including those under a certain Carrier Service Agreement, Customer's
        Monthly Revenue shall equal or exceed [*] each billing month under the
        term of this Agreement following a [*] (collectively, the "Monthly
        Commitment") under and during the Term of this Agreement. "Monthly
        Revenue" shall mean Customer's total monthly recurring and usage
        charges, after applicable discounts are applied, for Qwest services
        outlined in Exhibit A based upon rates shown therein and applied in
        accordance with Section 3 of this Agreement, exclusive of taxes,
        surcharges, and installation charges. In the event Customer fails to
        meet its Monthly Commitment in any month under this Agreement Customer
        will be required to pay the shortfall between that Monthly Commitment
        and the actual Monthly Revenue incurred by Customer.

3.      SERVICE RATES AND TERMS

        (A) Qwest service rates and terms are shown and described in Exhibit A.
        All discounts will be calculated based on total domestic and
        international usage and are applied to interstate usage charges, except
        the discount may not exceed the total interstate usage charge incurred
        in any month. If Customer does not maintain its Monthly Commitment as
        set forth above, the terms and conditions of Exhibit A shall apply.

<PAGE>   2
                         SWITCHLESS RESELLER AGREEMENT

        (B) Qwest reserves the right to change international rates upon five (5)
        calendar days notice and, domestic rates and Services described herein
        and in Exhibit A at any time upon thirty (30) calendar days prior
        written notice. Rate decreases and the offering of additional services
        may, in Qwest's sole discretion, be effective immediately upon or as of
        a date specified in a written notification to the Customer.

        (C) In the event that any regulatory agency, legislative body or court
        of competent jurisdiction promulgates regulations or modifies existing
        ones including, without limitation, regulations regarding payphone
        compensation, access charges and/or universal service ("Regulatory
        Activity"), Qwest reserves the right, at any time and upon written
        notice, to: (i) pass through to Customer all, or a portion of, any
        charges or surcharges directly or indirectly related to such Regulatory
        Activity; or (ii) modify the rates, including any rate guarantees,
        and/or other terms and conditions contained in this Agreement and/or the
        Tariff to reflect the impact of such Regulatory Activity.

        (D) Rates for Private Line Services and Services requiring dedicated
        access do not include installation, access and access-related charges,
        which are additional.

        (E) Customer shall pay all applicable federal, state and local taxes and
        surcharges unless and until Customer submits valid tax exemption
        certificates for an applicable tax. Credits or refunds of tax payments
        will not be issued to Customer for usage prior to the submission of tax
        exemption certificates.

        (F) Customer shall have the right to terminate this Agreement, in whole
        or in part, in the event of any material increase in rates for Services
        utilized by Customer, without penalty or fee.

4.      CUSTOMER SERVICE AND BILLING

        (A)     Customer acknowledges and agrees that it shall provide all
                billing, inquiry, and customer service to its own customers or
                end-users (the "End-Users"). Qwest shall only be obligated to
                provide customer service and services to Customer.

        (B)     Qwest will use commercially reasonable efforts to provide
                accurate bills and call detail to Customer on a monthly basis.
                The billing formats will be those available from time to time by
                Qwest, and are subject to change. There may be additional
                charges for certain billing formats requested by Customers.

5.      REPRESENTATION

        Customer shall not use any trademark, service mark, brand name or any
        other intellectual property of Qwest or any Qwest affiliate without
        Qwest's prior written consent. In no event shall Customer represent or
        state to End Users or prospective End Users that it has any relationship
        with Qwest other than an agreement to resell Qwest's services. Customer
        shall promptly and fully cooperate with Qwest to address and
        resolve all issues, problems, administrative procedures, End User
        complaints, regulatory investigations or inquiries, or any other
        circumstances arising from Customer's use or resale of Qwest Services.

6.      FINANCIAL RESPONSIBILITY, PAYMENT AND SECURITY

        Customer acknowledges that the Qwest invoices for services used by
        Customer (the "Invoices") are due upon receipt. Any payment received by
        Qwest later than thirty (30) calendar days after the

                                       2
<PAGE>   3
                          SWITCHLESS RESELLER AGREEMENT

      date of the invoice (the "Due Date") shall be subject to an interest
      charge on delinquent amounts at the rate of [*] of the late payment per
      month or the maximum lawful rate allowable under applicable state law,
      whichever is lower. Any applicable federal, state or local use, excise,
      sales or privilege taxes, duties, levies or similar liabilities,
      chargeable to or against Qwest because of the Service provided Customer
      shall also be charged to and payable by Customer. If full payment is not
      made when due, Qwest, in its sole discretion, shall have the right, after
      Qwest has given written notice to Customer, to suspend all or any part of
      the Service until such time as Customer has paid all unpaid balances
      (including interest), or to terminate all or any part of the Service.
      During any such suspension, and upon any such termination, no service
      interruption shall be deemed to occur. Customer acknowledges that it may
      not withhold any sums invoiced by Qwest for actual calls made by Customer
      including, without limitation, calls made by Customer's End Users and/or
      unauthorized third Parties (e.g., fraudulent calls) and charges to
      Customer's Qwest account(s). Customer will be responsible for full payment
      of all charges as reflected on any Qwest billing statement. Independent of
      Customer's payment obligations set forth in this section, Customer must
      notify Qwest within sixty (60) days of the invoice date of any contested
      or disputed amount concerning charges as they appear on the Qwest billing
      statement. Customer's notification of any contested or disputed amount
      must be in writing and sent to: 4650 Lakehurst Court, Dublin, Ohio 43017
      or to (614) 798-6460 by facsimile with duplicate notification to follow
      via regular U.S. Mail or overnight delivery. Written notification must be
      accompanied with a detailed written support, for any service interruption
      credit or other credit to which Customer believes itself entitled, and
      Qwest and Customer will promptly address and attempt to resolve the claim.
      Qwest, in its sole discretion exercised in good faith, may reject such
      documentation and/or explanation as inadequate and so notify Customer. The
      Customer shall then be entitled to a period of ten (10) additional
      business days to provide to Qwest additional documentation. If Qwest
      rejects this additional documentation, then the disputed portion of the
      bill shall be paid by Customer within ten (10) business days of Customer's
      receipt of Qwest's notice of inadequacy. If Qwest and Customer are unable
      to resolve any such claim, the matter may be submitted to arbitration
      pursuant to Section 26(A) - (E). All credits or adjustments for service
      outages will be made pursuant to applicable provisions of Qwest/LCI's
      Tariff F.C.C. No. 1 and Tariff F.C.C. No. 2 and applicable state tariffs
      which are on file with the Federal Communications Commission and
      applicable state regulatory bodies and which may be modified from time to
      time by Qwest in accordance with law. In consideration of the discounts
      offered by Qwest pursuant to this Agreement, with respect to any unpaid
      balance(s) owed by Customer to Qwest, Qwest shall have the right to offset
      such unpaid balance(s) from any amounts that Qwest owes to Customer and
      any of its affiliates.

      (C) Customer shall also provide and/or execute any additional collateral
      security document(s), including, an irrevocable letter of credit, a cash
      deposit, or a prepaid invoice amount, as may be required by Qwest, in
      Qwest's sole and reasonable judgment, if there is a material change in
      circumstances of Customer's actual or anticipated usage hereunder or
      Customer's financial condition during any time that Customer uses the
      Service.

7.    TERM

      The term of this Agreement shall begin on the Effective Date (defined as
      the date this Agreement is signed by an authorized officer of Qwest) and,
      subject to Section 2 above, will continue for a period of twelve (12)
      months after such date (the "Initial Term"); provided, however, that Qwest
      shall execute this Agreement as soon as possible following Customer's
      execution hereof, but in no event later than thirty (30) calendar days
      following Customer's execution. The Agreement shall be renewed,
      thereafter, on a monthly basis ("Renewal Term") at the Qwest standard
      rates in effect at the time of renewal until either Party provides the
      other Party with at least thirty (30) calendar days prior written notice
      of its intent to terminate this Agreement.

8.    OBLIGATIONS UPON EXPIRATION OR TERMINATION OF TERM OR RENEWAL TERM

      Upon expiration or termination of this Agreement, Customer shall pay all
      outstanding balances in accordance with Section 6 of this Agreement. Upon
      expiration or termination of this Agreement, Customer shall be fully
      subject to all terms and conditions, including standard tariffed rates,
      set forth in the Qwest/LCI Tariff for services received by Customer after
      such date.

9.    EARLY TERMINATION

      (A)   Customer shall have the right to terminate this Agreement during the
            initial term upon payment of an amount equal to the [*], or a pro
            rata portion thereof for any partial month, for each month remaining
            in the Initial Term of this Agreement; notwithstanding the
            foregoing, Customer shall not be liable for the early termination
            charges set forth herein in the event of an increase of a rate which
            materially affects Customer's Services, as set forth under Section
            3(A) of this Agreement or if Qwest fails to provide Customer with
            accurate billing tapes.

      (B)   Either Party may terminate this Agreement without liability or
            further obligation, except for unpaid charges as of the effective
            date of such termination, if Qwest is prohibited from furnishing the
            Service or if any material rate or term contained herein is
            substantially changed by order of the highest court of competent
            jurisdiction to which the matter is appealed, the FCC, or any other
            federal, state or local government authority.

      (C)   In addition, Customer represents, warrants and covenants that it
            understands that Qwest may, at any time, with written notice to
            Customer but without notice to End User(s), discontinue providing
            service to Customer in accordance with the terms of the Qwest/LCI
            Tariff and this Agreement and that such discontinuance may result in
            termination of service to the End User(s).

      (D)   Notwithstanding the foregoing, and without affecting Qwest's right
            to compensation accrued prior to the termination date, Qwest,
            without waiving any rights set forth in this Agreement or the
            Qwest/LCI Tariff, retains the right to terminate this Agreement
            immediately and without written notice, under any of the following
            circumstances:

            (i)   Customer becomes or is declared insolvent or bankrupt, is the
                  subject of any proceedings related to its liquidation,
                  insolvency or for the appointment of a receiver or similar
                  officer for it, makes an assignment for the benefit of all or
                  substantially all of its creditors, or enters into an
                  agreement for the composition, extension, or readjustment of
                  all or substantially all of its obligations;

            (ii)  Material change in Customer's ownership without written
                  consent of Qwest, which consent shall not be unreasonably
                  withheld; or

            (iii) Customer's failure to abide by all terms of Section 6 hereof,
                  including, without limitation, Customer's failure or refusal
                  to provide additional security or payment upon Qwest's
                  request, for any unethical or illegal acts on the part of
                  Customer, its officers, directors, employees, contractors,
                  agents, or servants;

                  this Agreement. Termination of this Agreement shall not affect

                  date; or

      (E)   Customer may terminate this Agreement without termination fee or

10.   Default

      It shall be a default under this Agreement, if Customer fails to pay Qwest
      in accordance with Section 6 of this Agreement. Upon default under this
      Section 10, Qwest shall be entitled to all rights and remedies under the
      Qwest/LCI Tariff and other applicable law in addition to all rights and
      remedies available to Qwest under this Agreement.

11.   Liability

      (A) OTHER THAN AS SET FORTH IN QWEST'S TARIFFS, IN NO EVENT SHALL QWEST,
      ITS AFFILIATES OR ITS CONTRACTORS BE LIABLE TO CUSTOMER OR ANY OTHER
      PERSON, FIRM OR ENTITY IN ANY OTHER RESPECT, FOR ANY DAMAGES, EITHER
      DIRECT, INDIRECT, CONSEQUENTIAL, SPECIAL, INCIDENTAL, ACTUAL, OR PUNITIVE
      DAMAGES, OR FOR ANY LOST PROFITS OF ANY KIND OR NATURE WHATSOEVER EVEN IF
      FORESEEABLE, ARISING OUT OF ANY MISTAKE, ACCIDENT, ERROR, OMISSION,
      INTERRUPTION, OR DEFECT IN TRANSMISSION, OR DELAY ARISING OUT OF OR
      RELATING TO THE SERVICES OR THE OBLIGATIONS OF QWEST PURSUANT TO THIS
      AGREEMENT AND ANY EXHIBITS THERETO INCLUDING, WITHOUT LIMITATION, ANY
      FAILURE TO PROVIDE BILLING TAPES WHICH ARE COMPATIBLE WITH CUSTOMER'S
      BILLING SYSTEM(S), OR ANY FAILURE TO TIMELY OR ACCURATELY PROVISION OR
      INSTALL ANY PORTION OF THE SERVICES, OR CONDITIONS WHICH MAY RESULT FROM
      ACTIONS BY REGULATORY OR JUDICIAL AUTHORITIES OR OTHER CARRIERS THAT QWEST
      RELIES ON TO PROVIDE SERVICE TO CUSTOMER. QWEST MAKES NO WARRANTY WHETHER
      EXPRESS, IMPLIED OR STATUTORY, AS TO THE DESCRIPTION, QUALITY,
      MERCHANTABILITY, COMPLETENESS OR FITNESS FOR ANY PURPOSE OF THE SERVICE OR
      LOCAL ACCESS OR AS TO ANY OTHER MATTER, ALL OF WHICH WARRANTIES BY QWEST
      ARE HEREBY EXCLUDED AND DISCLAIMED. FOR PURPOSES OF THIS SECTION, THE TERM
      "QWEST" SHALL BE DEEMED TO INCLUDE QWEST, ITS EMPLOYEES, OFFICERS,
      DIRECTORS AND AFFILIATES, AND ANY PERSON OR ENTITY ASSISTING QWEST IN ITS
      PERFORMANCE OR OBLIGATIONS UNDER THIS AGREEMENT.

      (B) If necessary to provision the Qwest Services to Customer, Qwest will
      install orders of Customer into the Qwest account system. Such
      installation shall be within a reasonable time and after receipt of such
      order by Qwest from Customer. Such installation may be by direct data
      transfer from Customer into the Qwest system or may be by manual
      installation. In the normal course of its business, Qwest will notify the
      Local Exchange Carrier ("LEC") of the orders that have been installed into
      the Qwest system. If the records of the LEC and those supplied to Qwest by
      Customer do not coincide in every respect, the LEC may reject the order
      installation from Qwest. In such event, if the End User has converted to
      Qwest service by the LEC for another reason, the End User will be billed
      by the LEC for any use of Qwest telecommunications services, the End User
      will receive Qwest Services at Qwest standard tariffed rates, and Qwest
      will receive the revenue from any use of the Qwest Services. If the LEC,
      for whatever reason, has not

                         SWITCHLESS RESELLER AGREEMENT

      designated Qwest as each End User's PIC, the End User will be billed in
      accordance with the records of the LEC. The Parties will use reasonable
      efforts to notify the other Party of any rejection of order installation
      by the LEC. Customer is responsible for determining the correct
      information for reinstallation of the order. Customer shall protect,
      indemnify, defend, and hold harmless Qwest from and against any claim of
      any person or entity regarding PIC changes or the failure to effect PIC
      changes. Customer understands that Qwest shall have no liability for any
      acts or omissions of LECs, including the making or failure to make PIC
      changes.

12.   Relationship

      Neither Party shall have authority to bind the other by contract or
      otherwise make any representations or guarantees on behalf of the other.
      Both Parties acknowledge and agree that the relationship arising from this
      Agreement does not constitute an agency, joint venture, partnership,
      employee relationship or franchise. Customer acknowledges and agrees that
      it is an independent contractor.

13.   Assignment or Sale

      This Agreement shall be binding on Qwest and Customer and their respective
      affiliates, successors, and assigns. Customer shall not assign, sell or
      transfer this Agreement or the right to receive the Services provided
      hereunder, whether by operation of law or otherwise, without the prior
      written consent of Qwest. Qwest may terminate this Agreement in the event
      of a change in control of Customer without Qwest's prior written consent,
      which consent shall not be unreasonably withheld by Qwest.

14.  PIC Authorizations

      (A)   Customer shall obtain a signed or verbal interexchange carrier
            ("PIC") authorization with true third Party verification and
            archived recordings according to state or FCC guidelines for each
            ANI ordered by Customer. Upon an oral or written request by Qwest,
            Customer shall immediately produce a copy of the written or verbal
            authorization. Qwest reserves the right not to process or turn up
            ANIs until Customer has produced appropriate written or verbal
            authorizations requested by Qwest. If Customer does not comply with
            the request for PIC authorizations, Qwest reserves the right not to
            accept additional ANIs until Customer complies.

      (B)   If Customer elects to provide only direct dial (or so-called "1+")
            services, and Qwest will act as the interexchange carrier ("IXC")
            for operator-assisted (or so-called "0+") traffic generated by
            Customer's end users, Customer agrees where appropriate to inform
            its end users that it:

            (i) designates Qwest as its primary carrier for 0+ operator assisted
            intraLATA long distance services;"

            (ii) designates Qwest as its primary carrier for 0+ operator
            assisted interLATA long distance services;" or

            (iii) designates Qwest as its primary carrier for 0+ operator
            assisted intraLATA and interLATA long distance services."

                          SWITCHLESS RESELLER AGREEMENT

      (C)   in the event an LEC or any regulatory entity assesses Qwest any
            charge, fine, forfeiture, or fee for improper or inadequate PIC
            authorizations relating to Customer's service, Customer shall
            promptly reimburse Qwest for all such charges plus a Qwest
            management fee of [*] per ANI ordered by Customer that is deemed to
            lack proper service authorization or PIC verification.

      (D)   Upon the request of Qwest, Customer shall promptly provide to Qwest
            or the LEC, at Customer's expense, any documentation required by the
            LEC regarding PIC selections or authorizations from Customer's End
            Users. In addition, Customer shall promptly and in good faith
            cooperate with Qwest and all LECs in investigating and attempting to
            resolve all PIC selection and authorization disputes.

      15.   Reporting Requirements

            Where reporting obligations or requirements are imposed upon Qwest
            by any third Party or regulatory agency that can be satisfied by
            Customer, Customer agrees to comply with such requirements and
            obligations and to hold Qwest harmless for any failure of compliance
            with any such requirement or obligation.

      16.   Governing Law, Certifications and Warranties

      (A)   Customer understands that Qwest in conducting its business in the
            manner set forth herein, is subject to the Communications Act of
            1934, as amended, and as interpreted and applied by the Federal
            Communications Commission. All terms of this Agreement not subject
            to the Communications Act of 1934 as amended and as interpreted and
            applied by the Federal Communications Commission will be interpreted
            according to New York law, without regard to its conflicts of law
            provisions. Any cause of action Customer may have with respect to a
            breach of this Agreement must be commenced within one (1) year after
            the claim or cause of action arises or such claim or cause of action
            is barred.

      (B)   If service is provided solely within a single state in a manner
            which subjects the Service to regulation by such state, then the
            terms and conditions of such Service and of this Agreement shall be
            subject to such regulations and to any Agreement to this Agreement
            relating thereto which is delivered by Qwest to Customer. Customer
            shall have the right to terminate this Agreement within ten (10)
            days of receipt of such Agreement without further liability
            hereunder.

      (C)   Customer certifies and warrants that it is in compliance with and
            will continue to be in compliance with all international, federal,
            state and local laws and regulations relating to its performance
            under this Agreement. Customer is solely responsible for obtaining
            all licenses, approvals, and regulatory authority for its operation
            and the provision of services to its End Users. Any breach of the
            obligations of Customer under this Section shall be a material
            breach of this Agreement. If Customer does not comply with this
            Section, in addition to any remedies available to Qwest at law or in
            equity, Qwest, in its sole discretion, may elect to decline to
            accept additional orders under this Agreement or may immediately
            terminate this Agreement without further liability or obligation to
            Customer.

      (D)   The Services are provided on an "as is" and "as available" basis
            without warranties of any kind, either express or implied.

17.   Terms and Conditions Surviving Termination or Expiration of Agreement

      The terms and conditions of the Qwest/LCI Tariff along with Section 6, 10,
      11, 12, 16, 18, 25, 26 and any provision hereof, which, by its context is
      intended to survive the termination or expiration hereof, shall also
      survive. Additionally, any obligation to hold harmless and indemnify a
      Party hereunder shall survive the termination or expiration of this
      Agreement.

18.   Indemnification

      Customer shall protect, defend, hold harmless, and indemnify Qwest from
      and against any claims, actions, damages, liabilities, costs, judgments or
      expenses (including attorney fees) arising out of (i) the resale or
      reselling of the Service, including but not limited to the provision or
      termination of service by Customer to End Users and any failure to provide
      service; (ii) any breach by Customer of any warranty, representation,
      obligation or covenant hereunder; (iii) and any instance of an
      unauthorized PIC change commonly referred to as "slamming" or failure to
      obtain a properly executed LOA as required by Section 14(B) herein.

19.   Cancellation, Blocking and Disconnect of Service

      Without affecting Customer's minimum usage or other obligations herein,
      Customer may cancel, disconnect, or terminate a portion of the Service
      when Customer's End User has provided a new PIC authorization to another
      carrier. Customer shall be financially responsible for Service provided
      under this Agreement until such time that the new PIC change is
      implemented. In the event Customer requests that an ANI be blocked from
      Qwest Services, Customer must certify that the request for blocking is due
      to an End User account being past due and delinquent and the End User has
      been properly notified.

20.   Nondisclosure

      Neither Party shall disclose to any third Party during the term of this
      Agreement and during the two (2) year period immediately following
      termination of this Agreement, any of the terms and conditions set forth
      in this Agreement unless disclosure is required by any state or federal
      governmental agency, otherwise required to be disclosed by law, or is
      necessary in any proceeding establishing rights or obligations under this
      Agreement. Each Party reserves the right to terminate this Agreement, upon
      written notification, of any disclosure prohibited hereunder.

21.   Non-Bell Usage Surcharge

      Customer will originate at least [*] of Customer's total usage of the
      Service in a tandem owned and operated by a Regional Bell Operating
      Company (RBOC) and subject to such RBOC's tariffed access charges. Qwest
      will apply a surcharge of [*] per minute of use to the number of minutes
      by which Non-RBOC originations exceed [*] of Customer's total usage of
      the Service.

22.   Amendments

      The Agreement, together with all Exhibits, represents the entire
      understanding of the Parties as it pertains to the subject matter herein.
      Any and all prior offers, agreements, representations and understandings,
      whether oral or written, shall be superseded by this Agreement. Exclusive
      of any Tariff modifications initiated by Qwest, once this Agreement has
      been fully executed, any

23.   Waiver

      Qwest's failure to insist upon or enforce strict performance of any
      provision of this Agreement shall not be construed as a waiver of any
      provision or right. Neither the waiver by either of the Parties hereto of
      a breach or a default under any provisions of this Agreement, nor the
      failure of either of the Parties, on one or more occasions, to enforce any
      of the provisions of this Agreement or to exercise any right or privilege
      hereunder shall thereafter be construed as a waiver of any subsequent
      breach or default of a similar nature, or as a waiver of any of such
      provisions, right, or privileges hereunder. Neither the course of conduct
      between Parties nor trade practice shall act to modify any provision of
      this Agreement.

24.   Notice

      Except when actual receipt is expressly required by the terms hereof, all

25.   SEVERABILITY

      In the event that any one or more of the provisions contained in this
      Agreement shall for any reason be held to be invalid, illegal or
      unenforceable in any respect, such invalidity, illegality or
      unenforceability shall not affect any other provision of this Agreement,
      but this Agreement shall be construed as if such invalid, illegal or
      unenforceable provision had never been contained herein. Further, in the
      event that any provision of this Agreement shall be held to be invalid,
      illegal or unenforceable by virtue of its scope or period of time, but may
      be made enforceable by a limitation thereof, such provision shall be
      deemed to be amended to the minimum extent necessary to render it valid,
      legal and enforceable or in the alternative both Parties shall negotiate
      in good faith to substitute for such invalid, illegal, or unenforceable
      provision a mutually acceptable provision that is consistent with the
      original intent of the Parties. The remainder of the provisions shall
      remain in full force and effect.

26.   ARBITRATION OF DISPUTES

      (A)   Any dispute arising out of this Agreement relating to Qwest invoices
            or balances owed by Customer to Qwest for Services rendered, which
            cannot be resolved between the Parties, shall be settled by binding
            arbitration at the office of the American Arbitration Association
            ("AAA") located in Washington, D.C. or Denver, Colorado, at the
            choice of the Party initiating the arbitration. The arbitration
            shall be held in accordance with the commercial Arbitration Rules of
            the American Arbitration Association ("AAA Rules"), as amended by
            this Agreement. Neither Party may seek injunctive relief of any kind
            prior to the confirmation of an arbitration award.

      (B)   Either Qwest or the Customer may initiate arbitration by providing
            written demand for arbitration, a copy of this Agreement and the
            administrative fee required by the AAA Rules to the AAA, 1150
            Connecticut Avenue, 6TH Floor, Washington, DC 20036-4104. A copy of
            the notice shall also be provided to the other Party. The remaining
            cost of the arbitration, including the fees and expenses of the
            arbitrator, shall be shared equally by the Parties unless the
            arbitration award provides otherwise. Each Party shall bear the cost
            of preparing and presenting its case.

      (C)   One Arbitrator shall be appointed in accordance with the AAA Rules
            within sixty (60) days of the submission of the demand for
            arbitration, unless both Parties otherwise agree in writing. The
            Arbitrator shall designate the time and place in the Washington, DC
            area for the hearing within thirty (30) days of his or her
            appointment. Qwest and the Customer agree that the Arbitrator's
            authority to grant relief shall be subject to the provisions of this
            Agreement, the United States Arbitration Act, ("USAA"), the ABA-AAA
            Code of Ethics for Arbitrators in Commercial Disputes, Qwest/LCI
            Tariffs, substantive law, and the Communications Act of 1934, as
            amended. The Arbitrator shall not be able to award, nor shall any
            Party be entitled to receive punitive, incidental, consequential,
            exemplary, reliance or special damages, including damages for lost
            profits. The Arbitrator's decision shall follow the plain meaning of
            the relevant documents, and shall be final, binding, and enforceable
            in a court of competent jurisdiction. The decision of the Arbitrator
            is appealable only for mistakes of law.

      (D)   Customer agrees to place One Hundred Per Cent (100%) of any invoiced
            sums it disputes into an interest-bearing escrow account pending
            completion of the arbitration. Qwest and the Customer agree to
            undertake all reasonable steps to expedite the arbitration process.

                     SWITCHLESS RESELLER SERVICES AGREEMENT

GENERAL

Interstate rates are per state and are for state-wide calling. The applicable
continental US Interstate rate is determined based upon the originating state of
an outbound call or based upon the terminating state of a toll-free inbound
call. Intrastate rates are per State and are for Statewide termination. Domestic
rates shown in the ReQwest Interstate and Intrastate Rate Exhibits are shown in
terms of full minutes and are billed in [*] increments.

International rates are per country and are for country-code wide termination.
International rates shown in the ReQwest International Rate Exhibit, with the
exception of Mexican rates, are shown in terms of a rate per minute and are
billed in [*] increments, with an initial [*] increment. Mexican calls are
billed in [*] increments. Directory Assistance calls are billed [*].

Calling Card rate billing increments vary by originating and terminating points
of the call and are listed in the Calling Card rate exhibit.

Rates shown in the ReQwest Rate Exhibits are Base Rates. Discounts, if any,
pursuant to the below Discounts Section and Discount Schedule.

Qwest reserves the right to charge excessive quantities (ie. [*] of Customer's
total calls) of short duration calls (i.e. calls under [*] in length) a minimum
of [*] per answered call.

ROUNDING

Currently, the ReQwest Switchless Reseller Service utilizes "bulk rounding". For
the purposes of this agreement, bulk rounding is defined as carrying over the
3rd and 4th place amounts of a call charge to the next call, and continuing to
do so until one full cent ($.01) is accrued. When this has occurred, the cent is
applied to the next call. In addition, the ReQwest Switchless Reseller Service
employs [*], which means that all calls are rounded [*], as opposed to [*] (e.g.
initial and incremental).

TOLL FREE SERVICES PORTABILITY

Qwest will provide toll free inbound services to End Users desiring to keep
their current toll free number and under the following condition:

      -     The End User signs a Letter of Agency designating Qwest as the
            Responsible Organization for the toll free number

Qwest will train the Customer on the proper procedures and documentation
required for toll free portability.

Qwest will provide to Reseller Responsible Organization Service and will charge
the following rates:

identified on Attachment A annexed hereto, (individually referred to as
"Company" and collectively as "Companies").

W I T N E S S E T H:

        WHEREAS, ILLUMINET is a corporation which was formed by
telecommunications companies situated throughout the United States of America
and for several years has been providing database management, billing services,

Services"); and

        WHEREAS, the Company provides a variety of telecommunications services
to its subscribers and wishes to provide new and improved services utilizing
SIGNET 7(R) Services; and

        WHEREAS, in connection with the offering of SIGNET 7(R) Services,
ILLUMINET shall maintain an Independent Line Information Database ("Independent

of all participants; and

        WHEREAS, the Company may participate in SIGNET 7(R) Services without
first upgrading its switch center to SS7 protocol, by providing line information
data to the Independent LIDB.

        NOW, THEREFORE, in consideration of the covenants and undertakings
herein contained and the mutual benefits to be derived herefrom, the adequacy of
which consideration is hereby acknowledged, ILLUMINET and the Company agree as
follows:

                         SECTION I: SCOPE AND STRUCTURE

        A. This Master Service Agreement specifies the general terms and
conditions pursuant to which ILLUMINET will perform certain services for the
Company. Additional terms and conditions pursuant to which the parties may
perform specific services or types of services will be set forth in "Modules"
that will be made and entered into by and between the parties, and upon the
execution of each such Module, shall be attached to and incorporated herein to
this Master Service Agreement and be subject to the terms and conditions of this
Master Service Agreement. Unless otherwise specified herein or implicit in the
context hereof, the term "Master Service Agreement" used herein shall include
any and all Modules hereto in effect from time to time.



                                                                    Page 2 of 11
<PAGE>   4

      B. Each Module incorporated in this Master Service Agreement shall contain
its own expiration and termination provisions and shall expire or terminate
individually in accordance with such provisions. This Master Service Agreement
shall remain in full force and effect in accordance with its terms from its
effective date until it expires or is terminated in accordance with the
provisions hereof, even if no Modules are in effect at any given time.

      C. In the event of any conflict or inconsistency between the provisions of
this Master Service Agreement (excluding Modules) and any individual Module of
this Master Service Agreement, the provisions of the Module shall control.

      D. ILLUMINET warrants that all services provided pursuant to this Master
Services Agreement, including all Modules hereunder, shall operate in
substantial accordance with ILLUMINET's corresponding User Guides, provided that
Company uses such services in substantial accordance with such User Guides.

                      SECTION II:   COMPENSATION

      The parties agree that the compensation to be paid by either party to the
other for services performed pursuant to this Master Service Agreement shall be
as specified in the applicable Module of this Master Service Agreement. Each
party agrees to pay the other party the compensation stated in each executed
Module, in accordance with all of the terms and conditions of such Module and
this Master Service Agreement. All payments made under this Master Service
Agreement shall be made in U.S. currency.

                SECTION III:   PROPRIETARY INFORMATION

      A. All information or other data relating to either party's business
activities which is disclosed by said party to the other party in connection
with this Master Service Agreement and/or any Module hereto, and designated as
proprietary or confidential information (hereinafter referred to as "Proprietary
Information") will be safeguarded and kept confidential by the other party to
the same extent that the other party protects its own proprietary and
confidential information, and shall be deemed the property of the disclosing
party. Such Proprietary Information in tangible form, and all reproductions
thereof, shall be returned to the disclosing party upon its request. The
receiving party shall not disclose or release any such Proprietary Information
without written authority from the disclosing party, to anyone other than an
employee, contractor, agent, attorney or affiliated company having a need for
such Proprietary Information in furtherance of the performance of services. The
receiving party shall require any



                                                                    Page 3 of 11

person not its employee to whom it discloses or releases any such Proprietary
Information of the other party to sign an agreement to protect the
confidentiality of such Proprietary Information as provided in this Agreement,
prior to such disclosure or release.

        B. Upon the expiration or termination of this Master Service Agreement,
each party, at the request of the other party, shall promptly, but in any event
within thirty (30) days following the date of such request, return any and all
copies of Proprietary Information in tangible form, that such party received
from the other party and is still in its possession, custody, or control. In
addition, each party shall delete or erase all Proprietary Information from its
computer systems within the same time period and certify such compliance to the
other party in writing, signed by an officer of the certifying party. In the
event of the expiration or termination of a Module hereto, each party shall
return or eliminate any and all Proprietary Information in its possession,
custody, or control which pertains solely to such Module or the contract of
services covered by such Module, in the same manner and within the same time
period as provided above in this paragraph.

        C. The provisions of this Section III shall survive the termination or
expiration of this Master Service Agreement and any Module hereto for a period
of three (3) years unless otherwise agreed in writing by both parties.

        D. Notwithstanding any other provision of this Section III, neither
party hereto shall be required to return or to delete or erase from its computer
systems, any Proprietary Information or portion thereof which such party has
received pursuant to this Agreement and is required to retain among its records
by law or applicable regulations. In the event either party hereto is required
by law or regulation to retain Proprietary Information disclosed to it which the
other party has requested to be returned, the party so retaining the Proprietary
Information shall advise the disclosing party of that fact and of the law or
regulation requiring such retention, and all such retained Proprietary
Information shall continue to be maintained confidential as provided in this
Agreement and in the applicable provisions hereof which shall survive the
termination or expiration of this Agreement.

                       SECTION IV: RESOLUTION OF DISPUTES

        A. INFORMAL RESOLUTION. The parties agree that they shall attempt to
resolve any dispute regarding any right, obligation, duty, or liability arising
out of the provisions of this Master Service Agreement or any Module through
informal discussions or negotiations prior to resorting to formal dispute
resolution procedures contained in Subsection B below. If, at any



                                                                    Page 4 of 11
<PAGE>   6

time following the commencement of any such discussions or negotiations, either
party determines such discussions or negotiations are not likely to result in a
reasonable resolution of the dispute, it may send to the other party a written
statement of the issues or problems being discussed or negotiated. If the
dispute has not been resolved within sixty (60) days after the mailing of the
said statement of issues, either party shall have the right to serve a written
demand for arbitration upon the other and thereby commence binding arbitration
in accordance with the provisions set forth below. The mailing of the statement
of issues and the passage of sixty (60) days from the date of the mailing of
such statement of issues shall be conditions precedent to the commencement of
any arbitration proceedings hereunder.

        B. BINDING ARBITRATION. Within five (5) working days of delivery of a
demand, each party shall designate an arbitrator. The two designated arbitrators
shall then select a third arbitrator to complete the full arbitration panel
within twenty (20) working days, or as otherwise agreed.

              The arbitration panel shall commence hearing within sixty (60)
days of the selection of the panel. The scope of document production and the
enforcement of document requests may be ordered by the arbitrators to the extent
economical and reasonable. All discovery requests shall be subject to the
proprietary rights of the parties, and the arbitrators shall adopt procedures to
protect such rights. Except where contrary to the provisions set forth in this
Master Service Agreement, the rules of the American Arbitration Association
("AAA") shall be applied, provided, however, that the arbitration need not be
conducted under the auspices of the AAA, in which event the fee schedule of the
AAA shall not apply.

              All costs of arbitration and any award of attorney's fees shall be
awarded pursuant to the provisions of Section XIX of this Master Service
Agreement.

              Unless otherwise agreed in writing, the parties shall continue to
provide service under any Module, honor all commitments under this Master
Service Agreement, and continue to make payments in accordance with this Master
Service Agreement during the course of dispute resolution pursuant to the
provisions of this Section.

                        SECTION V: SUCCESSORS AND ASSIGNS

        This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns; provided, however,
this Agreement shall not be assigned by either party hereto without the prior
written consent of the other party hereto, which consent shall not be
unreasonably withheld, except as provided in the next succeeding sentence. If
another corporation



                                                                    Page 5 of 11

which is a parent, a wholly-owned or controlled subsidiary of a parent ("Sister
Company") or a wholly-owned or controlled subsidiary of one of the parties
hereto shall succeed to some or all of the business of the corporation which is
a party hereto, such party hereto may assign this Agreement to such parent,
subsidiary or Sister Company, without the consent of the other party, if such
parent, subsidiary or Sister Company shall expressly undertake in writing the
performance of the obligation and duties of the party hereto which it is
succeeding pursuant to such assignment. Notwithstanding any other provision in
this Agreement, Company may assign this Agreement, in whole or in part, to any
entity acquiring substantially all of the stock or assets of Company.

                       SECTION VI: INDEPENDENT CONTRACTORS

        Each party agrees that it shall perform its duties, obligations, and
services hereunder as an independent contractor and not as the employee or
servant of the other party. Except as expressly provided in any Module, neither
party nor any personnel employed or furnished by such party shall be deemed the
agent, employee, or servant of the other party or be entitled to any benefits
available under any plans for such other party's employees. Each party has and
hereby retains the right to exercise full control and supervision over the
performance of its obligations under this Master Service Agreement and retains
full control over the employment, supervision, direction, compensation, and
termination of all of its employees assisting in the performance of such
obligations. Each party shall be solely responsible for all matters relating to
the compensation of its respective employees, including payment of all
employment taxes and withholdings due in respect of its employees. Each party
shall be responsible for its acts and those of its employees during the
performance of such party's duties and obligations hereunder.

                          SECTION VII: INDEMNIFICATION

        The indemnification provisions of this Section shall apply to all
matters arising under this Master Service Agreement except that indemnification
or limitation of liability or related provisions contained in any Module to this
Master Service Agreement shall be controlling and take precedence over this
Section.

        To the extent not prohibited by law, each party shall indemnify the
other and hold it harmless against any loss, cost, claim, injury, or liability
relating to or arising out of negligence or willful misconduct by the
indemnifying party or its agents or contractors in connection with any services
or duties under this Master Service Agreement.



                                                                    Page 6 of 11
<PAGE>   8

        The indemnifying party under this Section agrees to defend any suit
brought against the other party for any such loss, cost, claim, injury, or
liability. Each party agrees to notify the other party promptly, in writing, of
any written claims, lawsuits, or demands for which the other party is
responsible under this Section and to cooperate in every reasonable way to
facilitate defense or settlement of claims. The indemnifying party shall not be
liable under this Section for settlement by the indemnified party of any claim,
lawsuit, or demand if the indemnifying party has not approved the settlement in
advance unless the indemnifying party has had the defense of the claim, lawsuit,
or demand tendered to it in writing and has failed to assume such defense.

        No claims under this Section, or claims with respect to charges under
this Master Service Agreement or adjustments to such charges, or any other
claims with respect to this Master Service Agreement, may be made more than two
(2) years (or such greater time as may be set by law) after the date of the
event that gave rise to the claim; provided, however, that claims for indemnity
under this Section may be made within two (2) years (or such greater time as may
be set by law) of the accrual of the cause of action for indemnity. The mailing
of a statement of issues as provided in Section IV.A hereinabove shall
constitute a claim with respect to this Master Service Agreement for the
purposes of satisfying the claims limitation period requirements of this Section
VII.

                      SECTION VIII: LIMITATION OF LIABILITY

        In no event shall either party be liable to the other party for
incidental, special, or consequential damages including but not limited to lost
profits.

                        SECTION IX: YEAR 2000 COMPLIANCE

        ILLUMINET represents and warrants that the software, hardware and
equipment that it uses to provide services under this Master Service Agreement
will record, store, process, and present calendar dates falling on or after
January 1, 2000, in the same manner, and with the same functionality, as
performed on or before December 31, 1999.

                         SECTION X: COMPLIANCE WITH LAWS

      Each party shall perform all of its obligations and undertakings set forth
in this Master Service Agreement in compliance with all applicable laws, orders,
and regulations specifically including, without limitation, all applicable laws,
orders, and regulations prohibiting



                                                                    Page 7 of 11
<PAGE>   9

discrimination against any employee or applicant for employment by
reason of race, color, religion, sex, national origin, age, or disability.

        In the event of any conflict between any provision of this Master
Service Agreement and any applicable law, order or regulation (including,
without limitation, any order, rule or regulation of any regulatory agency
having jurisdiction over the Company which may effect the matters covered by
this Master Service Agreement), the parties agree to negotiate in good faith,
such reasonable modification(s) as may be required to resolve such conflict.

                            SECTION XI: FORCE MAJEURE

        Neither party shall be held liable for any delay or failure of
performance of any part of this Master Service Agreement arising out of or
resulting from any cause beyond its control and without its fault or negligence,
including, without limitation, acts of God, acts or omissions of civil or
military authority, government regulations, embargoes, epidemics, war, terrorist
acts, riots, civil commotion or civil uprisings, insurrections, fires,
explosions, nuclear accidents, strikes, lockouts, power blackouts, earthquakes,
floods, hurricanes, tornados, volcanic actions, or other similar causes beyond
its control. If such delay or failure occurs, the non-delaying party may elect
to (a) terminate this Master Service Agreement or any Module thereof for
services not already received, if such Force Majeure condition results in a
delay or failure to perform which continues for more than thirty (30) days; or
(b) suspend such services for the duration of the delaying cause, obtain
elsewhere the services to be bought or sold hereunder, and resume performance
under this Master Service Agreement once the delaying cause ceases. Unless
written notice is given within thirty (30) days after such non-delaying party is
apprised of the delay or failure, (b) shall be deemed selected.

                       SECTION XII: AMENDMENTS AND WAIVERS

        This Master Service Agreement may be amended only by a written agreement
signed by both parties. No course of dealing or failure of either party to
enforce any provision of this Master Service Agreement shall be construed as a
waiver of such provision or of any other provision of this Master Service
Agreement. The amendment of any provision of this Master Service Agreement shall
not constitute an amendment or modification of any other part of this Master
Service Agreement unless expressly stated in such written agreement.



                                                                    Page 8 of 11

receipt requested, addressed to such designated representative and address as
either party may from time to time provide by written notice to the other party,
and unless and until any further designation is made, such representative and

        In the event any provision of this Master Service Agreement shall be
held invalid or unenforceable by any Court of competent jurisdiction and if such
invalidity or unenforceability shall materially impair achieving the purpose and
intent of this Master Service Agreement, then this entire Master Service
Agreement shall be invalid and unenforceable. Otherwise, this Master Service
Agreement shall be construed as if not containing the particular provision or
provisions hereof held to be invalid or unenforceable, and the rights and
obligations of the parties shall be construed and enforced accordingly.

                    SECTION XVI: NO THIRD PARTY BENEFICIARIES

      delivery intervals set forth in the Attachments to this Agreement, or, if
      not specified therein, with Seller's standard order intervals in effect on

3.3   CHANGES IN CUSTOMER'S ORDERS

      Changes made by Customer to a purchase order which has been previously
      accepted by Seller (a "Change Order") are subject to acceptance by Seller.
      Change Orders shall be treated as a separate purchase order and shall
      follow the mutually agreed Change Order process. In the event Seller
      accepts a Change Order and such change affects Seller's ability to meet
      its obligations under the original purchase order any price (discount, if
      applicable), shipment date or Services completion date quoted by Seller
      with respect to such original purchase order is subject to change. Seller
      will provide to Customer written quotations and expected completion dates
      for any requested Change Orders and Seller will have ten (10) business
      days to accept or reject the new quotation and new completion dates.


      Seller agrees to use reasonable efforts to minimize any delayed shipment
      or completion date occasioned by such changes.


3.4   LATE DELIVERIES

      3.4.1 For delivery delays that are the sole fault of Seller, and provided
      that Customer is not in breach of this Agreement and has made invoice
      payments in accordance with this Agreement, Seller will use its best
      efforts to provide the delayed Deliverables to Customer expediently and at
      no additional cost to Customer.

      3.4.2 The parties agree that Seller's failure to meet the mutually agreed
      upon Installation Acceptance Date for the host switch and associated gray
      iron and power ("Host Switch Installation") will cause damages to Customer
      which are difficult if not impossible to ascertain and prove. The parties
      agree that subject to the terms and conditions set forth herein, Seller
      shall pay and Customer shall accept as liquidated damages, and not as a
      penalty, the amounts set forth in this paragraph. If due to Seller's
      action or inactions, Seller fails to meet such Installation Acceptance
      Date for the Host Switch Installation, Seller shall pay to Customer as
      liquidated damages for any loss or damage sustained by Customer an initial
      payment of [*] after a seven (7) day cure period and thereafter [*] per
      day, for a maximum of thirty (30) days (resulting in a maximum liability
      of [*]) for each host switch Installation Acceptance Date. With respect to
      any host switch installation for which the maximum liquidated damages
      become due to

      Customer hereunder, Customer shall have the right to cancel the Purchase
      Order with respect to such Host Switch Installation, receive a refund of
      all monies and Customer shall have no further liability or obligation with
      respect to such Purchase Order. Also, Seller shall not be liable or
      responsible for liquidated damages for any delay caused by (1) Customer
      changes, revisions, or modifications, or special requirements of Customer
      not communicated and agreed to by Seller in writing as specified in the
      Change Order process set forth in Section 3.3; (2) Customer's failure to
      meet intervals specified in Schedule of Milestones contained in Schedule
      ____ of Exhibit C; or (3) Customer's failure to have the Host Switch Site
      ready as defined by the Site Ready Checklist contained in Schedule _____
      of Exhibit C. Any damages for which Seller is liable pursuant as to this
      clause shall be credited against an invoice(s) for future Purchase Orders
      during the term as the partied may agree. To the extent Seller does not
      place Purchase Orders sufficient to credit all Late Delivery damages
      accrued within six (6) months of the thirty (30) day period, Seller shall
      refund to Customer that portion of the credit not previously credited.
      This provision for liquidated damages (and cancellation of the applicable
      Purchase Order) is intended to be and shall be in lieu of any other remedy
      and any other claims for damages to which Customer might otherwise be
      entitled for Seller's failure to timely meet the host switch Installation
      Acceptance Date.


3.5   CHANGES IN PRODUCTS

      Prior to shipment, Seller may, from time to time, make changes in Products
      with respect to future orders. Seller may modify the Product(s) drawings

      or Function under normal and proper use of the ordered Product as provided
      in Seller's Specifications. For changes that do impact the Form, Fit, or
      Function of the ordered Product, Seller shall notify Customer in writing
      one hundred eighty (180) days prior to the date that changes become
      effective. If Customer objects to the change, Customer shall notify Seller
      within thirty (30) days from the date of notice. Upon receipt of notice,
      Seller and Customer shall jointly determine acceptable Product
      alternatives.


3.6   PRICES

      Prices, fees, and charges ("Prices") for Deliverables and Services are set
      forth in Customer's Price Lists and based upon Seller's standard ordering
      and shipping intervals. If Customer desires to procure Deliverables or
      Services that are not listed in any of Customer's Price Lists, Customer
      may request that Seller provide an additional Customer Price List.


3.7   COMPETITIVE PRICE

      Provided that Customer is not in material breach of this Agreement after
      being notified by Seller in writing and given a reasonable opportunity to
      cure such breach Seller will, [*]. If Customer fails to cure a material
      breach of this Agreement within a reasonable time after being given
      written notice by Seller, the obligations of Seller under this section
      shall be suspended until such time as Customer cures the breach at which
      time Seller's obligations shall be reinstated with respect to purchases on
      and after the date of cure. If customer purchases Deliverables and
      Services for deployment in Canada, this Section shall apply to such
      purchases but the analysis shall be limited to Seller's other customers in
      Canada.

      replace the enjoined Product or Licensed Materials furnished pursuant to
      this Agreement with a suitable substitute free of any infringement without
      materially affecting Form, Fit or Function; (2) modify it so that it will
      be free of the infringement without materially affecting Form, Fit or
      Function; or (3) procure for Customer a license or other right to use it.

      Customer's trademark, trade name or other company identification; or (3)

      such Information only for the purpose of performing under this Agreement,
      and when Customer is the receiving party, Customer shall use such
      Information only (1) to order; (2) to evaluate Seller's Products, Licensed
      Materials and Services; or (3) to install, operate and maintain the
      particular Products and Licensed Materials for which the Information was
      originally furnished. Unless the furnishing party consents in writing,
      such Information, except for that part, if any, which is known to the
      receiving party free of any confidential obligation, which is
      independently developed by the receiving party without reference to the
      Information, or which becomes generally known to the public through acts
      not attributable to the receiving party, shall be held in confidence by
      the receiving party. The receiving party may disclose such Information to
      other persons (such as financial advisors, legal advisors, consultants,
      investors, customers, and suppliers), upon the furnishing party's prior
      written authorization, but solely to perform acts which this section
      expressly authorizes the receiving party to perform itself and further
      provided such other person agrees in writing (a copy of which writing will
      be provided to the furnishing party at its request) to the same conditions
      respecting use of Information contained in this section and to any other
      reasonable conditions requested by the furnishing party. Notwithstanding
      the foregoing, the receiving party may disclose information to the extent
      disclosure may be required by applicable laws or regulations, in which
      latter case, the party required to make such disclosure shall promptly
      inform the other prior to such disclosure in sufficient time to enable
      such other party to make known any objections it may have to such
      disclosure. The party required to make such disclosure shall take all
      reasonable steps and exercise all reasonable efforts directed by the other
      party to secure a protective order, seek confidential treatment, or
      otherwise assure that this Agreement and/or any order will be withheld
      from the public record.

      Any such notice shall be effective upon receipt. Each party may change its
      designated representative or address for receipt of communications and
      notices by giving written notice to the furnishing party.


3.21  FORCE MAJEURE

      Neither party shall be liable to the other party for any delay or failure
      in performance to the extent the delay or failure results from a Force
      Majeure. A Force Majeure is any cause which is beyond a party's reasonable
      control, including but not limited to fires, strikes, embargoes,
      explosions, earthquakes, floods, wars, water, the elements, labor
      disputes, government requirements, civil or military authorities, acts of
      God or by the public enemy, inability to secure raw materials or
      transportation facilities, acts or omissions of carriers or suppliers, or
      other causes , whether or not similar to the foregoing, in each case to
      the extent beyond such party's control. A party shall promptly notify the
      other party of the occurrence of Force Majeure, and the notifying party
      shall be excused from any further performance of the obligations affected
      by Force Majeure for as long as the Force Majeure continues, provided such


                     LUCENT TECHNOLOGIES INC. - PROPRIETARY
                                      -18-
<PAGE>   20

      party uses and continues to use its best efforts to recommence
      performance. If such delay or failure to perform extends for more than
      ninety (90) days, the other party may terminate the order or orders
      affected by Force Majeure upon written notice without liability for such
      termination.


3.22  ASSIGNMENT

      Except as provided in this section, neither party shall assign this
      Agreement or any right or interest under this Agreement, nor delegate any
      work or obligation to be performed under this Agreement (an "assignment")
      without the other party's prior written consent. Any attempted assignment
      in contravention of this shall be void and ineffective. Nothing shall
      preclude a party from employing a subcontractor in carrying out its
      obligations under this Agreement, subject to the other party's approval,
      which shall not be unreasonably withheld. A party's use of such
      subcontractor shall not release the party from its obligations under this
      Agreement. Notwithstanding the foregoing, either party has the right to
      assign this Agreement and to assign its rights and delegate its duties
      under this Agreement, in whole or in part, at any time and without the
      other party's consent, to any present or future subsidiary or Affiliate of
      such party or to any combination of the foregoing. Such assignment or
      delegation shall not release such party from any further obligation or
      liability thereon. In addition, each party shall have the right to assign
      this Agreement to an entity which acquires all or substantially all of the
      business, stock or assets of such party, whether by operation of law or
      otherwise, provided that the party acquiring Customer's business, stock or
      assets is not a direct competitor of Seller in providing Network Products,
      Software or Services. In such cases, the assigning party shall give the
      other party prompt written notice of the assignment. For the purposes of
      this section, the term "Agreement" includes this Agreement, all
      Attachments, any subordinate agreement placed under this Agreement and any
      order placed under this Agreement or subordinate agreement.


3.23  TERMINATION

      In the event either party is in material breach or default of the terms of
      this Agreement and such breach or default continues for a period of thirty
      (30) days after the receipt of written notice from the other party,
      excluding matters which are the subject of a good faith dispute under
      negotiation, then the party not in breach or default shall have the right
      to terminate this Agreement without any charge, obligation or liability
      except for Products or Licensed Materials already delivered and Services
      already performed.


3.24  INDEPENDENT CONTRACTOR

      All work performed by either party under this Agreement shall be performed
      as an independent contractor and not as an agent of the other, and no
      persons furnished by the performing party shall be considered the
      employees or agents of the other.


3.25  RELEASES VOID

      Neither party shall require releases or waivers of any personal rights
      from representatives or employees of the other in connection with visits
      to its premises, nor shall such parties plead such releases or waivers in
      any action or proceeding.


3.26  PUBLICITY

      For publication at a mutually agreed time, the parties will jointly and
      promptly create a press release to announce the execution of this
      Agreement and the formation of a relationship between Customer and Seller
      within thirty (30) days of the Effective Date. The press release will be
      subject to prior written consent of each party. Neither party shall issue
      or release for publication any articles, advertising, or publicity
      material relating to Products, Licensed Materials, or Services under this
      Agreement or mentioning or implying the name, trademarks,


                     LUCENT TECHNOLOGIES INC. - PROPRIETARY

      logos, trade name, service mark or other company identification of the
      other party or any of its Affiliates or any of its personnel without the
      prior written consent of the other party, which, if applicable, shall be
      provided as soon as practicable thereafter. Customer may use Seller's
      trade name, logo, trademarks, service marks and other company
      identification as provided in Exhibit F.


3.27  CONFIDENTIALITY OF AGREEMENT

      Notwithstanding the obligations contained in Section "Use of Information"
      of this Agreement the parties shall keep all provisions of this Agreement
      and any order submitted hereunder (including, without limitation, prices
      and pricing related information) confidential except as reasonably
      necessary for performance by the parties hereunder and except to the
      extent disclosure may be required by applicable laws or regulations, in
      which latter case, the party required to make such disclosure shall
      promptly inform the other prior to such disclosure in sufficient time to
      enable such other party to make known any objections it may have to such
      disclosure. The disclosing party shall take all reasonable steps and
      exercise all reasonable efforts directed by the other party to secure a
      protective order, seek confidential treatment, or otherwise assure that
      this Agreement and/or any order will be withheld from the public record.


3.28  EXPORT CONTROL

      The parties acknowledge that all Deliverables, related documentation, and
      technical information (including, but not limited to, service and
      training) provided under this Agreement are subject to U.S. export laws
      and regulations and any use or transfer of such Products, Software,
      related documentation, or technical information must be authorized under
      those regulations. Each party agrees that it will not use, distribute,
      transfer, or transmit the Products, Software, related documentation, or
      technical information (even if incorporated into other products) except in
      compliance with U.S. regulations. If requested by Seller, Customer also
      agrees to sign written assurances and other export-related documents as
      may be required for Seller to comply with U.S. export regulations.


3.29  AMENDMENTS

      Any supplement, modification or waiver of any provision of this Agreement
      must be in writing and signed by authorized representatives of both
      parties.


3.30  SEVERABILITY

      If any portion of this Agreement is found to be invalid or unenforceable,
      the parties agree that the remaining portions shall remain in effect. The
      parties further agree that in the event such invalid or unenforceable
      portion is an essential part of this Agreement, they will immediately
      begin negotiations for a replacement.


3.31  WAIVER

      If either party fails to enforce any right or remedy available under this
      Agreement, that failure shall not be construed as a waiver of any right or
      remedy with respect to any other breach or failure by the other party.


3.32  SURVIVAL

      The rights and obligations of the parties, which by their nature would
      continue beyond the termination cancellation, or expiration of this
      Agreement, shall survive such termination, cancellation or expiration.

3.33  SECTION HEADINGS

      The section headings in this Agreement are inserted for convenience only
      and are not intended to affect the meaning or interpretation of this
      Agreement.


3.34  CHOICE OF LAW

      The construction and interpretation of, and the rights and obligations of
      the parties pursuant to this Agreement, shall be governed by the laws of
      the State of California without regard to its conflict of laws provision
      and excluding the United Nations Convention on the Sale of Goods. All
      disputes arising out of this Agreement shall be subject to the exclusive
      jurisdiction and venue of the United States District Court for the
      Northern District of California, or if there is no federal jurisdiction,
      the California state courts of San Francisco, California, and the parties
      consent to the personal and exclusive jurisdiction of these courts.


3.35  DISPUTE RESOLUTION

      3.36.1 Senior management of either party may, upon notice and within five
      (5) business days of receipt of a notice from the other party, elect to
      utilize a non-binding resolution procedure whereby each party presents its
      case before a panel consisting of two senior executives of each of the
      parties and, if such executives can agree upon such an individual, a
      mutually acceptable neutral advisor. If a party elects to use the
      procedure set forth in this clause, the other party shall participate. The
      hearing shall occur no more than ten (10) business days after a party
      serves notice to use the procedure set forth in this clause. If the matter
      cannot be resolved by such senior executives, the neutral advisor, if one
      has been agreed upon, may be asked to assist such senior executives in
      evaluating the strengths and weaknesses of each party's position on the
      merits of their dispute. The parties shall each bear their respective
      costs incurred in connection with the procedure set forth in this clause,
      except that they shall share equally the fees and expenses of the neutral
      advisor, if any, and the cost of the facility for the hearing.

      If the parties are unable, in good faith, to reach a settlement of the
      matter submitted to mediation, upon notice to the other party, either
      party may elect to file a lawsuit in a court of competent jurisdiction.
      Similarly, if one party refuses or fails to comply with the procedure
      described above, upon notice to the non-compliant party, the other party
      may elect to file a lawsuit in a court of competent jurisdiction.

3.36  AMBIGUITIES

      The parties represent that they are sophisticated businesses with access
      to their own legal, financial and business advisors and that each party
      has had the opportunity to consult with advisors of their own choosing
      before entering into this Agreement. The parties therefore acknowledge and
      agree that the rule of law that ambiguities are construed against the
      drafter shall not apply to the interpretation of this Agreement.


3.37  INSURANCE

      Each party shall maintain during the term of this Agreement, at its own
      cost and expense, carry and maintain at a minimum, the insurance coverage
      listed below. If either party is not self-insured, that party shall
      maintain such coverages having a "Best's" rating of at least B+XIII.
      Seller shall not commence any work hereunder until each party has
      fulfilled all insurance requirements herein. Each party shall require its
      subcontractors and agents to maintain the same insurance coverage listed

            be subcontracted), premises-operations, products/completed
            operations and contractual liability with respect to the liability
            assumed by either party hereunder.

      -     The limits of insurance shall not be less than:

            -     Each Occurrence (Bodily Injury/Property Damage) $1,000,000.00

            -     General Aggregate Limit (Annual Aggregate) $2,000,000.00

            injury and property damage.

      The insurance limits required herein may be obtained through any
      combination of self-insurance, primary and excess or umbrella liability
      insurance. Each party shall furnish the other prior to the start of the
      work, if requested by the other, certificates or adequate proof of the
      insurance required by this clause. Each party shall notify the other in
      writing at least thirty (30) days prior to cancellation of or any material
      change in the policy. Notwithstanding the above, each party shall have the
      option where permitted by law to self-insure any or all of the foregoing
      risks.


3.38  FACILITIES ACCESS

      Each party shall provide the other with reasonable access to its
      facilities required in connection with the performance of their respective
      obligations under this Agreement. No charge shall be made for such access.
      Reasonable prior notification will be given when access is required.

              ARTICLE 4 PROVISIONS APPLICABLE TO LICENSED MATERIALS


4.1   LICENSE FOR LICENSED MATERIALS

      Upon delivery of Licensed Materials and payment of the applicable license
      fee(s) to Seller, Seller grants to Customer a perpetual, irrevocable,
      non-terminable and nonexclusive license to Use Licensed Materials in North
      America for its own business operations. No license is granted to Customer
      to Use the Licensed Materials outside North America or to sublicense such
      Licensed Materials furnished by Seller. Customer shall not reverse
      engineer, decompile or disassemble Software furnished as object code to
      generate corresponding Source Code, except as authorized by applicable
      law. Unless otherwise agreed in writing by Seller, Customer shall not
      modify Software furnished by Seller under this Agreement, except as
      authorized in Section 4.8 or otherwise authorized herein or in the
      Documentation. Further, Seller shall offer maintenance and support
      services for such Licensed Materials in accordance with mutually agreed
      terms and conditions.

      Customer shall not copy Software embodied in Firmware, except as necessary
      for its Use. Customer shall not make any copies of any other Licensed
      Materials except for backup and archival copies and as otherwise necessary
      in connection with the rights granted hereunder. Customer shall reproduce
      and include any Seller copyright and proprietary notice on all such
      necessary copies of the Licensed Materials. Customer shall also mark all
      media containing such copies with a warning that the Licensed Materials
      are subject to restrictions contained in an agreement between Seller and
      Customer and that such Licensed Materials are the property of Seller.
      Customer shall maintain records of the number and location of all copies
      of the Licensed Materials. Customer shall take appropriate action, by
      instruction, agreement, or otherwise, with the persons permitted access to
      the Licensed Materials so as to enable Customer to satisfy its obligations
      under this Agreement. If the Licensed Materials are no longer needed by,
      or useful to Customer, Customer shall return all copies of such Licensed
      Materials to Seller or follow written disposition instructions provided by
      Seller.

      Seller shall provide, at no extra cost to Customer, up to three (3) copies
      of the Application Software for use in Customer testing facility ("Testing
      Software"). Customer shall not make additional copies so the "Testing
      Software" and expressly agrees that it will not use the Testing Software
      for commercial service or for any purpose other than testing, and
      migration planning for entities to be acquired by Customer, provided that
      the period of use for migration planning shall not exceed 120 days. In
      addition, the testing Software may be used for disaster recovery at a fee
      to be mutually agreed.


4.2   CHANGES IN LICENSED MATERIALS

      Prior to shipment, Seller at its option may at any time modify the
      Licensed Materials, provided the modifications, under normal and proper
      Use, do not materially adversely affect the Use, function, or performance
      of the ordered Licensed Materials and such Licensed Materials continue to
      conform to the Specifications, and provided that Customer receives thirty
      (30) days notice of such modifications and an opportunity to cancel such
      order without charge. Unless otherwise agreed in writing, such
      substitution shall not result in any additional charges to Customer with
      respect to licenses for which Seller has quoted fees to Customer.


4.3   NON-CANCELLATION OF LICENSE

      The parties acknowledge that licenses to Use the Licensed Materials,
      together with the Products and Services, are critical to Customer's
      business operations, and as such, Seller may not under


                     LUCENT TECHNOLOGIES INC. - PROPRIETARY
                                      -23-
<PAGE>   25

      any circumstances terminate or cancel Customer's licenses hereunder or
      otherwise prevent Customer from Using the Licensed Materials (except as
      provided below), and such licenses shall survive any expiration or
      termination of this Agreement. If Customer fails to comply with any of the
      material terms and conditions of this Agreement with respect to the Use of
      Licensed Materials and such failure is not corrected within sixty (60)
      days of receipt of written notice thereof by Customer, then Seller shall
      be entitled to recover damages including direct and consequential damages
      for Customer's breach of license(s), not to exceed [*]. If Customer's
      failure to comply with such terms and conditions involves the disclosure
      of proprietary or confidential Information or impairs the protection of
      Seller's intellectual property, Customer acknowledges that Seller will
      suffer irreparable harm and damages will be insufficient to compensate
      Seller. Accordingly, in such event Seller shall be entitled to injunctive
      and other equitable relief to insure ongoing compliance with the
      applicable terms and conditions of the license, but not to prevent
      Customer's use of the Licensed Materials in accordance with the license
      terms and conditions. In addition, until such time as Customer cures its
      failure to comply with such terms and conditions, Seller shall have no
      obligation to grant any additional licenses or deliver any additional
      Software hereunder.


4.4   OPTIONAL SOFTWARE FEATURES

      Software provided to Customer under this Agreement may contain optional
      features that are separately licensed and priced. Seller shall notify
      Customer regarding all such features prior to or concurrent with delivery
      of the Software. Customer understands and agrees that such optional
      features will not be activated without written authorization from Seller
      and Customer's payment of the appropriate license fees. Seller will
      identify all locked-out features of Seller- developed Software. If, in
      spite of Customer's best efforts to comply with this restriction, such
      features are activated, Customer agrees to so notify Seller within five
      (5) business days from the date of Customer's knowledge that such features
      were activated and to either pay Seller the current license fees charged
      by Seller for the activated features or allow Seller to promptly
      deactivate such features.

4.5   ADDITIONAL RIGHTS IN LICENSED MATERIALS

      Customer may relocate the Software from time to time, as long as Customer
      remains in compliance with the license restrictions set forth herein. Upon
      Seller's reasonable request from time to time, Customer shall provide
      Seller a report regarding the current locations of the Software. Seller
      will not unreasonably withhold its consent to Use outside the United
      States provided that the proprietary information associated with the Use
      can be adequately protected and any other reasonable concerns of Seller

            concerns of Seller are adequately addressed;

      (b)   Before any such Software shall be transferred, Customer shall notify
            Seller of such transfer and the transferee shall have agreed in

      (c)   Within North America, the transferee shall have the same right to
            Software warranty or Software maintenance for such Software as the
            transferor, provided the transferee continues to pay the fees, if
            any, associated with such Software or Software maintenance.

      (d)   In no event shall such transfer be made to any competitor of Seller
            who is in the business of developing or manufacturing comparable
            systems.


4.9   SOURCE CODE ESCROW

      At Customer's request and expense and subject to the terms of a mutually
      negotiated escrow agreement with an independent escrow agent reasonably

      copy of the human-readable source code and available documentation
      therefor (collectively, "Source Code") for certain Seller-developed
      Application Software licensed under this Agreement. The Source Code shall
      be for Application Software and not apply to host switch Software or to
      host switch optional Software features.

      The Source Code escrow agreement shall provide for release of the Source
      Code to Customer if and when one of the following events occurs:

      (a)   Seller becomes insolvent or makes an assignment for the benefit of
            creditors;

      (b)   A petition is filed by or against Seller under any state or federal
            bankruptcy or insolvency law alleging that Seller is insolvent or
            unable to pay debts as they mature, which petition is not withdraw
            or stayed within sixty (60) days;

      (c)   Seller announces it is will discontinue manufacture of the
            Application Software and will no longer maintain the Application
            Software;

                                      -25-
<PAGE>   27

      (d)   Seller ceases to maintain a standard, supported version of
            Application Software furnished pursuant to this Agreement, and
            support services are not available from another entity (either
            working with or independently from Seller);

      (e)   Seller's enhancements and development of the Application Software
            require migration to a different operating environment and Seller no
            longer provides standard support services for the version of the
            Application Software that runs on the operating system used by
            Customer;

      (f)   A court determines that Seller has continuously and repeatedly
            breached its obligations under this Article 4 and has failed to cure
            its breach.

      If the Source Code is released to Customer as provided above, Seller
      grants Customer a nonexclusive, nontransferable, limited right to use and
      modify the Source Code only to the extent necessary to maintain and
      enhance the corresponding Application Software.

            written approval, such approval to not be unreasonably withheld,
            specific Services to third parties and to use independent
            consultants provided that the use of subcontractors and/or
            consultants will not cause any interruption of Services to Customer.

6.1   PRODUCTS AND SOFTWARE

      Seller warrants to Customer only, that during the applicable warranty
      period (I) Products (exclusive of Software) will be free from defects in
      material and workmanship and will conform to the Specifications for such
      Products; (ii) Software will be free from those defects which materially
      affect performance in accordance with the Specifications.

      The warranty period for switching, transmission and optical hardware
      Products and the associated Software (acquired with the Product that

      of [*], in each case commencing on acceptance by Customer as set forth in
      this Agreement. The warranty period for any Product (or part thereof)
      repaired or replaced under this section is the unexpired portion of the
      new Product warranty period or [*], whichever is longer.

      If, under normal and proper use, a defect or non-conformity appears in
      Products or Software during the applicable warranty period and Customer
      notifies Seller in writing of such defect or non-conformance during such
      period or promptly thereafter and follows Seller's instructions regarding
      return of defective or non-conforming Product or Software, Seller, at its

      Seller shall pay the costs of transportation of the repaired or replacing
      Product or Software to any United States destination designated by
      Customer. If the returned Product or Software is not defective, Customer
      shall pay Seller's reasonable costs of handling, inspecting, testing and
      transportation and, if applicable, travel and related expenses. In
      repairing or replacing any Product, part of Product, or Software medium
      under this warranty, Seller may use either new, remanufactured,
      reconditioned, refurbished or functionally equivalent Products or parts.
      Replaced Products or parts shall become Seller's property. Response and
      restoral times during the warranty period will be the same as the

      Seller shall repair or replace the Products at Customer's site. Customer,
      at its expense, shall make the Products accessible for repair or
      replacement.

6.2   YEAR 2000

      falling on or before December 31, 1999, and (c) correctly calculate and
      compare date data between the twentieth and twenty-first centuries without
      impairment of the functioning of the Software, including recognition of
      the year 2000 as a leap year. All of the foregoing functionality shall be
      known as "Year 2000 Capability". In the event Customer has or licenses
      more than one version of "Year 2000 Capable" Software, such versions of
      Software, if they are intended by Seller to interoperate, will be
      compatible and interoperate in such manner as to process between them, as
      applicable, date related data correctly as described herein. All of the
      foregoing functionality shall be known as "Year 2000 Interoperability".
      The foregoing sets forth an additional warranted specification for
      Software developed by Seller that Seller has identified as having "Year
      2000 Capability". The failure of such Software to meet such specification
      during the Year 2000 Warranty Period shall, to the extent the Software
      remains then subject to warranty protection, entitle Customer to the
      remedies set out in this Section 6.1. Moreover, nothing in the foregoing
      shall be deemed to make Seller responsible for the "Year 2000 Capability"
      or "Year 2000 Interoperability" of any third party software interoperating
      or intended to interoperate with Software developed by Seller. Customer
      and/ or the manufacturer or other supplier of such third party software
      shall be responsible for such compliance and assuring the ability of such
      software to successfully operate while interoperating with Software
      developed by Seller.

6.3   SERVICES

      Seller agrees to perform Services in a professional and workmanlike
      manner, in accordance with the Statement of Work and Specification for
      such Services, and in accordance with good usage and accepted practices in
      the community in which Services are performed using material free from
      defects except where such material is provided by Customer. If Services
      performed by Seller are not so performed, and if Customer notifies Seller
      to that effect within a thirty (30) business day period commencing on the
      date of completion of the service, Seller will correct any defects and
      deficiencies or, if after using its best efforts, Seller is unable to
      correct such defects and deficiencies, Seller shall render a full refund
      of the original charge for the defective or deficient Service. Seller may
      offset any refund amounts by Seller to Customer against amounts due from
      Customer to Seller.

      If engineering or installation Services only are not performed as
      warranted, and Customer so notifies Seller within a three (3) month period
      commencing on the date of completion of the Services, Seller will correct
      the defect or non-conforming Services or, if after using its best efforts,
      Seller is unable to correct such defects and deficiencies, Seller shall
      render a full refund of the original charges for the defective or
      deficient Services. Seller may offset any refund amounts by Seller to
      Customer against amounts due from Customer to Seller.

      Seller represents, warrants and covenants that Seller is familiar with the
      intended use by Customer of the Network as described in this Agreement and
      in the applicable Operations Plan and that the Network and its associated
      Deliverables are suitable for and will satisfy such use and the terms of
      this Agreement in all respects, including the Network Architecture and
      design and Product recommendations.

      Seller represents and covenants that the Network, if implemented in
      accordance with the Network Architecture, is designed to and will

      interface and interoperate during the Term of this Agreement, Seller shall
      initiate corrective actions after receipt of notice of the defect or
      failure and shall promptly cure such defect at Seller's sole cost and
      expense. This warranty shall not apply to the extent that a failure
      results from (i) the Network being installed at Customer's direction by a
      party other than Seller and said Installation is not in accordance


                     LUCENT TECHNOLOGIES INC. - PROPRIETARY

      more of the active voice channels then in service with the host switch
      Network for a period of time exceeding five (5) minutes, or the loss of
      capability of a multi-line 15 or more lines end-user customer to originate
      or terminate any calls on all of its lines for a period of time exceeding
      five (5) minutes.


      6.5.3 During the warranty period, Business Hour Outage damages will be
      calculates as follows: [*] of the Business Hour Outage, plus [*] for each
      minute the duration of the Business Hour Outage exceeds [*].


      6.5.4 "Other Outages" is an Outage which occurs during a time other than a
      Business Hour Outage. As used herein, "Other Outage" means an unscheduled
      loss of functionality of a host switch Network for the reason set forth in
      Section 6.5.1 above which results in the capability to originate or
      terminate [*] or more of the active voice channels than in service within

      customer to originate or terminate any calls on all of its lines for a
      period of time exceeding ten (10) minutes.


      6.5.5 During the warranty period, Other Outage damages will be calculated
      as follows: [*] for the first thirty (30) minutes of the Other Outage,
      plus [*] per minute for each minute the duration of the outage exceeds
      30 minutes.


      6.5.6 In the event a Second Outage occurs within thirty (30) days of a
      prior Outage (the "First Outage"), the Outage damages specified in
      Sections 6.5.3 and 6.5.4 will be [*]. In the event a Third Outage occurs
      within thirty (30) days of the First Outage, the Outage damages set forth
      in Sections 6.5.3 and 6.5.4 will be [*].


      6.5.7 In no event will Seller's liability for Outage damages pursuant to
      either Section 6.5.3 or Section 6.5.4 exceed [*] with respect to each

      within thirty (30) days of a First Outage and [*] in the event of a Third
      Outage occurring within thirty (30) days of a Second Outage.

      In addition, the Seller's total liability for all Outage damages for the
      Network will not exceed [*] per calendar year until Customer deploys more
      than [*] host switches. For each additional host switch deployed by
      Customer, the damage total liability cap will increase by [*]. These
      Outage damages will be Customer's sole remedy for any failure in Network
      performance as set forth in this Agreement.


      6.5.8 Any damages for which Seller is liable pursuant to this Section
      shall be credited against an invoice for future Purchase Orders during the
      term as the parties may agree. To the extent, Seller does not place
      Purchase Orders sufficient for Customer to utilize the entire Outage
      Credit in the six months after the Outage Credit accrues, Seller shall
      refund the unused portion of the Outage Credit to Customer.


      6.5.9 Notwithstanding the foregoing, Seller will have no liability for:

      (i) Outages caused by a Force Majeure;

      (ii) Outages resulting from a mutually agreed scheduled activity such as
      Network maintenance or loading of Software that does not exceed the

      this Agreement or the Exhibits.

      (v) Outages resulting from an end user customer to which this Section
      applies failing to properly maintain its Network or otherwise follow
      operating procedures, based on standard industry processes applicable to

<TABLE>
<CAPTION>
        IMA-CA PRODUCT:                                      WARRANTY PERIOD:
        ---------------                                      ----------------
        <S>    <C>                                           <C>
        1.     New IMA-CA System (IMA-CA Software and        [*] from Installation Date
               IMA-CA Products) with COD

        2.     COD upgrades and expansions (IMA-CA           [*] Installation Date

      COD features or incremental units of capacity, ports or mailboxes have
      been enabled for which Customer has not paid the specified price or
      license fee, OCC will notify Customer and request that Customer pay the
      specified price or license fee within thirty (30) days. If Customer fails
      to (1) pay the specified price or license fee, (2) turn off the

System site.


      8.a POST WARRANTY: After the expiration of a IMA-CA Product or IMA-CA
      Software warranty, Customer may order Technical Assistance and Parts
      Replacement Agreement Program ("TAPRA") in accordance with Schedule C
      attached hereto. If Customer chooses not to order TAPRA, OCC will provide
      maintenance service to Customer on a time and materials basis at OCC's
      then-current rates. OCC will make parts and materials available at its
      then-current prices; provided, however, Customer shall receive a [*]
      credit toward any such parts if the replaced part is returned to OCC
      within ten (10) days after receipt of its replacement. For a period of
      five (5) years from Acceptance of each IMA-CA Product and item of IMA-CA
      Software, OCC will make available maintenance and support and spare parts
      as described in this Section and in Schedule C.


      8.b SOFTWARE SUPPORT: OCC will periodically provide performance related
      engineering modifications and changes ("Engineering Updates") at no charge
      during warranty, while under TAPRA, or for Services provided by Seller
      under Exhibit B in conformance of the Agreement. Additionally, OCC will
      provide safety related changes, and modifications at no charge. Customer

      OCC will introduce software and/or hardware features that enhance the
      functionality of IMA-CA Products or IMA-CA Software ("Upgrades"). Upgrades

      the time of purchase of such Upgrades.

9.     SYSTEM INTEGRATION

During the term of this Agreement, IMA-CA Systems purchased from OCC will
interface with the Simplified Message Desk Interface (SMDI) enabled Lucent Host
Switch. In addition, OCC will make commercially reasonable efforts to Integrate
IMA-CA Systems with Lucent Host Switches purchased by Customer during the term
of this Agreement. For purposes of this section, "Integrate" shall mean that an
IMA-CA System interoperates with a Lucent Host Switch to in a manner that is
functionally equivalent to how IMA-CA Systems interoperate with 5ESS host
switches.


In the event the Customer chooses to buy a Lucent Host Switch which does not
Integrate with the IMA-CA System at the time of purchase, Customer's IMA-CA
purchase commitment as set forth in Section 2.5 of the master Agreement will be
suspended, only until such time as the IMA-CA is able to integrate with the
Lucent Host Switch (the "Suspension Period"). Customer's purchase commitment of
[*] IMA-CA Systems and related Voice Messaging Services shall be reduced by the
number of Lucent Host Switches purchased during the Suspension Period, and
Customer shall have no obligation to purchase IMA-CA Systems or related Voice
Messaging Services for any Lucent Host Switches which are purchased during the
Suspension Period.

      any agreement in effect as of the Effective Date between OCC and any third
      party from whom OCC has licensed any portion of the IMA-CA Software, then
      the license grant in Section 4.1 and/or Section 4.3 shall be deemed
      amended, solely with respect to the IMA-CA Software and solely to the
      extent necessary to comply with such agreement, to provide OCC a limited
      right to terminate Customer's software license upon Customer's material
      breach which remains uncured for a reasonable period of time after written
      notice thereof. In addition, solely with respect to IMA-CA Software,
      replace "not to exceed [*] with [*]."


      10.a.2         Section 4.8 is expressly amended to add the following:

<PAGE>   40

      Before Customer may transfer any Software license rights to the IMA-CA
      software to any reseller of voice messaging equipment, Customer shall
      obtain OCC's written approval, which shall not be unreasonably withheld.

      10.b IMA-CA SOFTWARE LICENSE TERMS WITH COD:

      10.b.1. INCREMENTAL CAPACITY LICENSED AS SEPARATE IMA-CA SOFTWARE

      for by Customer, and whose enablement has been authorized and directed by
      OCC, will be licensed to Customer. Customer specifically acknowledges that
      only OCC is entitled to authorize the enablement of any IMA-CA Software
      (or features thereof) and that Customer will not enable (remotely or
      otherwise) or attempt to enable any IMA-CA Software (or features thereof),
      nor will it authorize or assist any third party to do so. Customer will
      promptly notify OCC if it has knowledge of any third party attempt to
      enable IMA-CA Software (or features thereof).

      10.b.2. CONDITIONS FOR ENABLEMENT OF IMA-CA SOFTWARE FEATURE PRODUCTS. To
      facilitate OCC's enablement of IMA-CA Software features and capabilities,
      Customer will make available remote system-level access to Customer's OCC

      IMA-CA Software License at the following times: (i) at the time of
      enablement of any separately licensed IMA-CA Software feature or
      capability, such as incremental capacity for OCC's IMA-CA Products, and
      (ii) once each calendar year upon three (3) business days' notice to
      Customer from OCC. Customer agrees to cooperate with OCC or its authorized
      agent in conducting such audits including making available remote system
      level access to Customer's IMA-CA Systems for such purpose.

to supportable hardware and software levels, as specified by OCC, prior to
entering into or renewing this TAPRA Program.

2.2        REPLACEMENT PARTS

Replacement parts are provided from OCC factory depots and airport locations at
no charge if the replaced part is returned undamaged to OCC within thirty (30)
days of receipt of replacement part. Otherwise, Customer will be charged the
then-current rate in the Price List for the replacement part.

Replacement parts can be ordered 24 hours/day, 7 days/week with non-urgent
delivery during normal coverage hours. OCC is responsible for the costs of
surface shipment of a replacement part to Customer. Customer is responsible for
shipping costs of replaced part to OCC and any costs for expedited shipment

hardware components and/or the installation of IMA-CA Software patches or

ALLOWANCE PERIOD For any quarter that you accrue funds, you will have four
quarters in which to spend those OCC ADvantage Fund dollars. Any money accrued
and not spent within the twelve-month window will be forfeited. As you
participate in the OCC ADvantage Fund, a summary statement of your accruals and
claims will be sent to you monthly. This statement will include your available
funds, funds about to expire, and your previous accrual and claim activity.

PRIOR APPROVAL REQUIREMENT All marketing projects must receive prior approval.
Prior Approval Forms (contained in this package) must be filled out completely
and faxed or mailed to your OCC Account Manager. MEDIANET will return a copy of
the form to you once the project is approved. You will not be approved for funds
exceeding the amount currently available in your OCC ADvantage account.

CHANGES TO PRIOR Approvals If you make any changes to your prior approval
including delaying the start and end dates of your marketing program, please
notify MEDIANET and submit a new Prior Approval Form.

REIMBURSEMENT AMOUNT You will be reimbursed with OCC ADvantage Funds for 100% of
any preapproved expenses for the promotion of qualifying OCC products and
services. In the event that the marketing project contains information on
products or services in addition to Octel's products and services, you will be
reimbursed for the percentage devoted to Octel, as determined by MEDIANET
("Octel's Share," see Guidelines Matrix). The amount paid will be based on
actual invoices for the marketing project, not the amount estimated on your
Prior Approval Form. The amount will be paid as long as funds are available.
Taxes will not be reimbursed.

MARKETING RESULTS REQUIREMENT Octel requires that the Marketing Results Form be
filled out completely for each marketing project within 60 days after the end
date of the program. This information will be kept confidential on an individual
customer basis. Information will be shared in consolidated report form by region
and type of business. These forms will automatically be sent to you from
MEDIANET. Future prior approvals will not be granted until all outstanding
Marketing Results Forms have been received. Additional forms are available from
MEDIANET.

CLAIM REJECTION If you do not send MEDIANET all of the required documentation
and proof of performance, your claim will be rejected. MEDIANET will ask you to
forward the missing information and upon receipt, your claim will be paid.

                            GENERAL SUPPLY AGREEMENT

                            VOICE MESSAGING SERVICES

        This Exhibit B to the Agreement, together with its Schedules attached
hereto (collectively, the "Exhibit"), contains the terms and conditions under
which Seller shall provide certain voice/data information storage and retrieval
services. In case of any conflict between the provisions of this Exhibit and the
Agreement with respect to the Services described in this Exhibit, the provisions
of this Exhibit shall control.

1.      DEFINITIONS.

Capitalized terms used in this Exhibit shall have the meanings set forth in the
Agreement. Additional capitalized terms or capitalized terms with meanings
specifically related to this Exhibit are also set forth below:

modify a Mailbox or Enhanced Mailbox.

Billable Mailbox means a block of computer disk memory resident on a Voice Mail
Platform associated with a Mailbox or an ECP Application.

Call Answering means the Service whereby the Voice Mail System will, subject to
the operation of the telecommunication equipment, facilities and services of
Customer and the applicable Subscriber, receive telephone calls directed to
Seller from Customer. Upon accessing the Voice Mail System, callers directed to
the Voice Mail System will hear a customized greeting and will then be provided
with instructions regarding use of the Voice Mail System. The Voice Mail System
will store verbal/data message(s) (subject to storage limitations) which the
caller chooses to leave. Additionally, telephone calls received by the Voice
Mail System may be directed to a specific Mailbox which will provide the caller
with the User's personal greeting if Customer's equipment provides compatible
in-band or out-of-band integration with the Voice Mail System.

Central Office Switching System Integration/Call Answering means the combined
Service whereby the Voice Mail System will, subject to the operation of the
telecommunication equipment located at the premises of Customer and the
applicable Subscriber and the CENTREX systems, facilities and services of the
applicable LEC, receive unanswered telephone calls, provide the caller with
instructions regarding use of the Voice Mail System, dispatch message waiting
indication information packets to Customer's PBX/CO in accordance with Seller's
Specifications, and store verbal/data message(s) (subject to storage
limitations) which the caller chooses to leave. As used herein, unanswered
telephone calls include those not answered because the intended recipient's
telephone station either is in use at the time of the telephone call or is not
answered within a predetermined number of rings.

Customer Site means one of the locations set forth in SCHEDULE C at which a
Voice Mail Platform will be deployed. Additional locations may be added to
SCHEDULE C in the future with the written consent of Seller.

Enhanced Call Processing (ECP) Application means the application which creates
one or more Enhanced Mailboxes and links such Enhanced Mailboxes together to
perform the functions requested by Customer (subject to the capabilities of the
Voice Mail System). The series of choices in an ECP Application is called a menu
and one or more menus linked together comprise an ECP Application. Development
of an ECP Application requires that a graphical representation of the menu(s)
accompany the order to Seller to create the requested linkages between the
requested Enhanced Mailboxes.

Enhanced Mailboxes means the following types of Mailboxes that deliver specific
information or routing instructions to calling parties as described in Seller's
Specifications: "Enhanced Call Processing Mailbox" (Types 30, 31, 32, 33);
"Information Center Mailbox" (Types 1, 2, and 3); "Bulletin Mailbox"; "Transfer
Mailbox"; "Conditional Transfer Mailbox"; and "Voice Forms Mailbox" (Types 10

fashion alarm conditions are acknowledged and acted upon by initiating trouble
tickets and notifying Seller Network Services Operations Personnel to contact

capacity planning, services availability, System downtime, mean time to correct
statistics, and monthly service performance metrics); and (b) the billing
statistics in the mutually agreed medium and format as provided in SECTION 3.4.

Message Waiting Indicator (MWI) - (Integrated Services to Customer Premise
Equipment Telephone Systems ONLY) is a means to visually notify a User of the
arrival of a message in the User's Mailbox. The notification consists of
illuminating a light on the User's telephone instrument. Upon retrieval of any
messages contained in the Mailbox, the Voice Mail System will subsequently
extinguish the light.

Message Networking means the class of service assigned to a specific Mailbox
allowing the applicable User to transmit a message(s) to the Mailbox(s) of other
User(s) established on one or more different Voice Mail Platforms.

the operation of the PBX(s) and other telecommunication equipment located at a
Subscriber's premises, receive, via dedicated facilities, unanswered telephone
calls, provide the caller with instructions regarding use of the Voice Mail
System, provide for "on/off" control of a User's message waiting indicator and
store any message (subject to storage limitations) which the caller chooses to
leave. As used herein, unanswered telephone calls include those not answered
because the intended recipient's telephone station either is in use at the time
of the telephone call or is not answered within a predetermined number of rings.

this Exhibit to add additional Services which will be made available to Customer
or to delete Services previously made available to Customer. Prior to deleting
any Service from this Exhibit, Seller will provide Customer at least sixty (60)
days advance notice of deletion. Upon deletion from this Exhibit, a Service will
cease to be included within the definition of "Services" and Customer will stop
marketing those services to Subscribers and potential Subscribers. Seller will
not delete a Service from this Exhibit, unless such Service is being generally
discontinued.

2.2 Customer shall request delivery of Services in writing and specify the date
at least thirty (30) days in advance of the date on which such Services are to

3.2 Seller will use its commercially reasonable efforts to fulfill all accepted
Administrative Change orders pursuant to SCHEDULE B, SECTION 1.

Customer and Seller. Such billing information will be rendered monthly to
Customer representing a period of 30 days as mutually agreed.

3.5 At Customer's request, Seller will prepare and mail User Documentation Kits
to the Customer sales office specified in the order entry documents (postage
incurred will be billed separately). Seller's marketing communications group
will, as requested, reasonably assist Customer to develop, publish and
distribute customized promotional, informational and educational materials and
documentation.

3.6 Seller will use its commercially reasonable best efforts to provide written
quotes for Services not covered by this Exhibit within 5 business days of
receipt through normal channels of all necessary information required to render
a proper quotation.

rendering marketing and sales support and will use commercially reasonable
efforts to provide answers within 3 days of request with the procedure subject
to agreement by both parties.

Platforms (when provided by Seller) with the latest Seller software that can be
successfully deployed and supported by Seller.

3.9 Seller will notify Customer, not less than ninety (90) days in advance, of
upcoming Software releases that will cause a change in fulfillment or the user
interface materials.

3.10 As Customer requests and Seller technically is able to deliver, special
custom-type Mailboxes may be created using "classes of service" meeting various
feature/functionality requests made by potential Subscribers of Customer. Such
Mailboxes will be developed and provided upon mutually agreeable terms and
conditions.

3.11 Promptly following the written request of Customer and receipt of all
required graphical representations, Seller will create and activate ECP
Applications per the scheduled delivery times as indicated in SCHEDULE B.

escalation support to expedite resolution of outages and to coordinate fault
isolation with Customer and with other of Customer's suppliers. Seller will
provide required travel and labor as part of providing the Services. As
necessary, Seller will initiate corrective action upon receipt of an alarm or
trouble report and will ensure impairments and outages are resolved in
descending order of severity. Seller will begin the repair process once a
trouble ticket has been created. Remote Remedial Maintenance will begin
initially and generally resolves troubles reported. Should on-site Remedial
Maintenance procedures be required, Seller targets on-site response of six (6)
hours during business days and twenty four (24) hours during non-business days.

4.      CUSTOMER'S DUTIES AND OBLIGATIONS.


4.1 In the event that Customer does not use frame relay circuits that connect
with the Lucent NRC, Customer will connect at its sole expense to 3410 Midcourt,

training to all Users. Customer will provide and cause to be delivered to Seller
collateral materials (requested by Subscribers) for assembly into end-user kits
("User Documentation Kits"). Such User Documentation Kits will be "private
labeled" and appear uniquely different from any then current Seller fulfillment
materials. Customer will provide Seller, upon Seller's request, with sufficient
initial and replacement inventory of Customer developed User Documentation Kits
for use by Seller when executing the end-user collateral fulfillment process
(postage will be paid by Customer).

4.4 Customer and/or Lucent NRC will designate and staff a Customer Voice Mail

days of execution of this Agreement, mutually agreed upon Mailbox Models.

4.9 Customer will use the secure facilities provided in Exhibit __ to house the

include sufficient power sources to operate all switching and voice mail
equipment co-located at those facilities.

agreed upon by both parties) including, but not limited to codes for designating
Mailbox Models, prior to transmission of the order entry documents to Seller
(via facsimile equipment or pursuant to some other mutually agreed method) for
processing.

4.11 Customer will use its reasonable efforts to cause its other vendors to
cooperate with Seller in connection with the installation, testing, modification
and problem evaluation of Voice Mail System components as necessary for Seller
to provide the Services, provided that Seller will not commit Customer to any
charges from such suppliers without Customer's advance written approval.
Customer acknowledges that the failure of such vendors to cooperate with Seller
will excuse Seller from any resulting breach of this Exhibit or any failure to
meet its performance obligations hereunder.

4.12 Customer will provide access by Seller employees/agents to the sites for
purposes of installation, testing, maintenance and inspection of the Voice Mail
System.

4.14 Neither Customer nor its Affiliates will move any Voice Mail Platform
deployed at a Customer Site without the written consent of Seller.

4.15 Customer acknowledges and agrees that Customer will be solely liable for
ensuring that access requested by its officers, directors, agents, employees
and/or Affiliates to messages contained in Mailboxes is obtained in accordance
with the requirements of applicable law. Customer will indemnify Seller and its
officers, directors, employees, agents and Affiliates against and hold each of
them harmless from any and all liabilities, costs, damages, judgements and
expenses (including reasonable attorney's fees and costs) arising out of or
attributable to Seller providing Customer and/or Customer's officers, directors,
employees, agents and/or Affiliates with access to or assisting Customer and/or
Customer's officers, directors, employees, agents and/or Affiliates in obtaining
access to the content of messages contained in Mailboxes, provided that such
access was requested by Customer.


5.      PRICING, INVOICING TO CUSTOMER AND PAYMENT TERMS.

5.1 The fees and Prices for the Services are those set forth in SCHEDULE A.


6.      LIMITATION ON LIABILITY.

Solely with respect to the Services provided pursuant to this Exhibit B:

Seller shall have no liability to Customer or to anyone else for any damages,
losses, liabilities, injuries, claims, demands or expenses arising out of or
directly or indirectly connected with the disclosure or loss of information
deposited in the Voice Mail System by Users or others, except to the extent such
damages, losses, liabilities, injuries, claims, demands or expenses arise out of
or result from the negligence or willful misconduct of Seller. Seller will
provide individual identification numbers for each User of the Services and will
use its commercially reasonable best efforts to ensure that the identification
numbers are not disclosed except to Customer and personnel of Seller who require
such information to administer the Services. Users may further protect such
identification numbers by the addition of a password as explained in the User
Documentation Kits, and are encouraged to do so. The Parties acknowledge that
Seller is providing the Services to Customer in lieu of Customer providing such
Services on its own behalf. The intent of this Exhibit is not to shift to Seller
any potential liability resulting from unauthorized access to the Voice Mail
System or to make Seller a surety with respect to such liabilities. Accordingly,
Customer agrees to remain fully liable for damages resulting from unauthorized
access as if, with respect to such damages, Customer were providing the Services
on its own behalf. Notwithstanding the foregoing, Seller will be fully liable
for any damages arising from unauthorized access to the Voice Mail System, if
such access is due to Seller's failure to use its commercially reasonable best
efforts to safeguard identification numbers issued to Users or if such damages
are otherwise due to the willful misconduct or negligence of Seller.
Notwithstanding the foregoing, nothing in this Section 6 is intended to limit
any warranties or remedies set forth in the Agreement or Exhibit A with respect
to the Voice Mail System or the other services provided under this Agreement.



7.      REPRESENTATIONS AND WARRANTIES OF SELLER.

7.1 Seller warrants that the Services will meet the Performance Standards as
stated in SCHEDULE B. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY FOR THE
SERVICES PROVIDED UNDER THIS EXHIBIT AND IS IN LIEU OF ALL OTHER WARRANTIES
EXPRESS OR IMPLIED INCLUDING (WITHOUT LIMITATION) THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR PARTICULAR PURPOSE.

7.2 This Section 7.2 is intended to supercede the provisions of Section 6.5
(Network Performance) of the General Supply Agreement except as herein provided.
In addition, this Section 7.2 supercedes any remedy that might otherwise be
available under Section 6.3 of the General Supply Agreement for failure to
achieve the System Availability standard set forth in Section 7 of Schedule B
hereto. Seller shall issue the following service credits if the Voice Mail
Systems for which Seller is providing Services experience an Outage. For
purposes of this Section 7.2, an "Outage" is defined as the inability of a Voice
Mail Platform to accept calls, record messages, store messages, and allow users
to retrieve their respective messages. "Outage" is further defined as any of the
events



Confidential                           6
<PAGE>   60
stated in the immediately preceding sentence occurring to a minimum of 25% of
the ports on a Voice Mail Platform, or the lesser of (a) 25% of the mailboxes on
a System or (b) 50 of the mailboxes on a System. In the event that Seller is
unable to satisfy its performance obligations within fifteen (153) minutes of
notification of an Outage, Seller will issue a service credit of [*] per Outage
per Platform. If the same Outage (e.g., failure of the same TIC card or
processor) occurs more than one time in the same month, the amount of the credit
Seller shall issue will increase by [*] for each subsequent occurrence. For
example, for the second occurrence of the same Outage, the credit shall be [*];
for the third occurrence of the same Outage, the credit shall be [*]. The total
Outage credits that Seller will issue for Outages in a particular in any month
shall not exceed the monthly billable fee paid for services. Notwithstanding the
foregoing, Seller will have no liability for: (i) Outages caused by a Force
Majeure; (ii) Outages resulting from a mutually agreed scheduled activity such
as Network maintenance or loading of Software that does not exceed the scheduled
Outage interval (iii) Outages resulting from Customer's, its subcontractor's or
any third party's (employed by the Customer) failure to follow the
Documentation; (iv) Outages resulting the failure of Customer to have (a)
competent technicians available to respond to notification from Seller, or (b)
adequate spares as recommended by Seller on site to repair the problem or (c)
from Customer's failure to perform an assigned responsibility under this
Agreement, the Attachments of the Operations Plan. (v) Outages resulting from an
end user customer to which this Section applies failure to properly operate its
Network or otherwise follow applicable Maintenance procedures.


Notwithstanding the foregoing, Seller will not be liable for any breach arising
out of any modification or attempted modification by Customer of the hardware or
software products used by Seller to provide the Services, unless Customer has
obtained prior authorization from Seller permitting such modification.

F.      Order Flow

All Administrative Change requests will be made on a mutually agreed upon form
by an authorized, designated Customer contact. Said request will be made, via a
mutually agreed upon media, to Seller's designated employee or agent.

SECTION 2. HELPDESK

Seller will provide a toll free number to the HelpDesk for call handling. The
HelpDesk provides a point of contact for Subscribers and Users to report
problems and obtain assistance with the Voice Mail System.

Seller's goals in answering HelpDesk calls are to ensure (i) at least 70% of
HelpDesk calls will be answered within 20 seconds or less directly by an
employee/agent as calculated over a calendar month (ii) calls that enter the
automatic call distributor queue will remain in queue for a targeted average of
1.5 minutes or less as calculated over a calendar month and (iii) Seller will
resolve all informational or User assistance HelpDesk tickets within forty-five
(45) minutes of the time reported to the HelpDesk. Failure to achieve these
goals will not constitute breach of this Exhibit.

SECTION 3. MONITORING

A.      Error Dispatcher

Seller will monitor Customer's Voice Mail System twenty-four (24) hours per day,
seven (7) days per week. Monitoring is defined as conducting polling events
utilizing polling computer technology which electronically retrieves error and
status logs. Such polling is typically performed in sixty (60) minute intervals.
Upon extraction of the error logs (i.e. polling action) Seller processes and
analyzes the error log for possible system problems/errors. If an error is
detected, the NOC will begin immediate resolution procedures. An Seller
employee/agent is present at the NOC twenty-four (24) hours a day, seven (7)
days a week for trouble resolution and corrective action. All error and status
log extractions are stored for fourteen (14) days following collection.

B.      Access Manager

Seller will dial each system access number utilized by Customer's Voice Mail
System, detect the system greeting, gain access to a test Mailbox, detect a
pre-recorded tone and disconnect. Each system access number is tested at least
twice between the hours of 10:00 PM and 6:00 AM CST. If a problem is detected,
the NOC will begin



Confidential                           14
<PAGE>   68

immediate resolution procedures. An Seller employee/agent is present at the NOC
twenty-four (24) hours a day, seven (7) days a week for trouble resolution and
corrective action.

SECTION 4. TROUBLE TICKET RESOLUTION

On behalf of Customer, Seller will manage the escalation and resolution of
trouble tickets, which is a record of Major and/or Minor Outages identified by
monitoring or reported to the HelpDesk. Seller's employee or agent will
diagnose, investigate and where possible, remotely correct the reported outage.
If any outage can not be corrected from the NOC, the trouble ticket associated
with such outage will be escalated to the appropriate Seller employee/agent and
continually documented and tracked until resolution.

SECTION 5. REPAIR RESPONSE

Seller will respond promptly to all outages identified by monitoring or reported
to the HelpDesk. Seller will classify each outage as a Minor Outage or Major
Outage. If a Major Outage is identified, Seller will immediately begin remote
diagnostics and corrective actions as mutually defined by Customer AND Seller.

All outages not classified as Major Outages are considered Minor Outages and
will be responded to within twenty-four (24) hours.

Seller will provide required travel, labor and parts as part of the cost of
providing Services. Replacement spare parts will be furnished on an exchange
basis and may, at the discretion of Seller, be new, re-manufactured, or
refurbished; provided any such re-manufactured or refurbished replacements are
equivalent in functionality to new parts and are in good working condition.

SECTION 6. TROUBLE TICKET ESCALATION

Customer may escalate any trouble ticket at any time by calling the HelpDesk and
asking to speak to a HelpDesk supervisor. Major Outages will be escalated every
two (2) hours until resolution.

SECTION 7. SYSTEM AVAILABILITY

Seller will maintain each Voice Mail Platform with 99.9% system availability
based on twenty-four (24) hour system availability. The system availability will
be calculated monthly, as a percent as follows:

        System Availability =   A-B
                                ---
                                 A

        Where:       A =    Total minutes in a calendar month less total minutes
                            of scheduled downtime in such month

                     B =    Total minutes of Major Outage in such month less
                            on-site response time, if required.

SECTION 8. SCHEDULED DOWNTIME

Seller will perform preventive maintenance procedures designed to keep the Voice
Mail System in operating condition and capable of performing in accordance with
the manufacturers' specifications. Seller and Customer will mutually agree on
the scheduling of preventive maintenance procedures with a view toward
minimizing interruptions of normal business activities. Seller will identify,
prior to performance, any preventive maintenance procedures which may result in
any disruption of User Services to Customer.

Seller will provide Customer with a request for scheduled downtime at least one
week in advance (normally between 11:00 PM and 6:00 AM local time) for any
scheduled maintenance procedures, system hardware and software enhancements,
disk expansions, system splits, user moves or special projects. Seller will
obtain Customer approval prior to the performance of any such procedures. If
Customer restricts Seller from performing required preventive maintenance
procedures, Seller will be relieved from any liability for resultant failures
and the downtime, if any, associated with that failure.

<PAGE>   69

SECTION 9. EQUIPMENT UPGRADES

Seller will, at mutually agreed upon times, perform installation of software,
hardware and/or safety engineering changes required or recommended by the
manufacturer. Seller will first notify and obtain advance written authorization
from Customer to perform such installations. At its discretion, Customer may
refuse to allow installation of engineering changes not required for safety
reasons; however, such a refusal will relieve Seller from any liability for
resultant failures and the downtime, if any, associated therewith.

SECTION 10. CAPACITY MANAGEMENT

A.      Grade of Service  (GOS)

Seller agrees to electronically monitor Voice Mail Platform line group traffic
statistics from each Voice Mail Platform to proactively identify capacity
issues. Upon identification of a capacity issue, Seller will notify Customer and
recommend a course of action for resolution. Customer will provide the final
approval before any action is taken.

Seller collects capacity statistics as part of monitoring services. The
statistics are compiled, processed and analyzed in seven-day periods. Capacity
reports are generally available within ten (10) days following the close of the
seven-day monitoring period. These statistics provide a set of data that is used
to compute the daily busy hour Erlangs and the corresponding statistical Erlang
B GOS. Busy hours are determined by dividing each business day into twenty-four
(24) one (1) hour periods and identifying the hour which carried the most
traffic Unless otherwise specified, the capacity metrics used to initiate a
proactive capacity issue notification to Customer are as follows:

<TABLE>

        Outbound from Voice Mail    P.30 (30%                3
        Platform                    blocking)
</TABLE>


        Inbound Voice Mail Platform line groups are typically used for
        voicemail access and Call Answering functions. Outbound Voice
        Mail Platform line groups are typically used for paging,
        networking and FAX delivery functions.

B.      Disk Storage

Seller collects and reviews Voice Mail Platform disk storage statistics as part
of monitoring services. The statistics are compiled, processed and analyzed in
seven-day periods. Capacity reports are generally available within ten (10) days
following the close of the seven-day monitoring period. These statistics
identify the available disk storage as a percent of total storage by Voice Mail
Platform. Upon identification of a storage availability issue, Seller will
notify Customer and include a recommended course of action for resolution.
Customer will provide the final approval before any action is taken.

Unless otherwise specified, the metric used to initiate a disk storage
availability issue notification to Customer is as follows:

<TABLE>
<CAPTION>
        NUMBER OF SAMPLES IN A MONTH EXCEEDING            MINIMUM UNUSED STORAGE

</TABLE>

        Note:   Customer has the responsibility of identifying any future events
                that might influence the recommend course of action, as it
                relates to capacity planning.

                        required to permit Seller to modify existing equipment.

In the event the joint site survey conducted by the parties pursuant to this
Section determines that the necessary requirements are not met at the
commencement of the installation of the Products and the Customer needs to
arrange for alterations and/or repairs, the order will be placed on hold until
such time as requirements are met. During such interval, Seller reserves the
right to determine any schedule and price impacts, to treat such product as Bill
and Hold, or to cancel such order. Customer shall be responsible for and agrees
to pay the applicable cancellation fee if Seller cancels such order.



                8.3.2   IMA-CA SITE REQUIREMENTS

        (a)     Purpose: This Schedule defines the power, physical and
                environmental requirements for the equipment room to be
                furnished by the CUSTOMER for the IMA-CA, the form of which may
                be revised by Octel from time to time. It is the responsibility
                of the CUSTOMER to ensure that these requirements are met.
                Conformance to site requirements will ensure maximum reliability
                of the system. CUSTOMER assumes responsibility for equipment
                room compliance to applicable building and electrical codes.

        (b)     Power Source: OCTEL systems require a dedicated power circuit
                from the facility's primary power source. The power panel
                provided for the systems will have an isolated ground connected
                to the service entry ground using a continuous insulated
                conductor the same size as the current carrying conductors. The
                service entry ground will be connected to a single point ground,
                such as a ground rod, building structural steel, or other
                approved ground source defined by the National Electrical Code.
                Water pipes are not an acceptable ground for this technology.

<PAGE>   80


        (c)     Power Requirements: A system administrator terminal requires one
                outlet at 117 VAC, 60 Hz, 10 amps, 3-wires with a dedicated
                ground. An optional printer connecting to the terminal requires
                the same power.

        (d)     Power Conditioning: The Systems are extremely resistant to
                transient voltages in comparison to most computing devices.
                However, in areas where electrical storms pose a danger,
                consider installing transient protection device in the power
                lines. This is particularly important where power is provided by
                outside overhead lines. Installing the Systems onto the same AC
                line with copy machines, elevators, air conditioning units or
                other motor-driven devices is not recommended, unless proper
                power conditioning is installed to isolate the system from AC
                power surges and fluctuations.

        (e)     Equipment Room Space: The CUSTOMER will provide approximately 36
                inches in front, sides and rear of the equipment which will
                allow sufficient space for access to the equipment for service
                personnel. Space provided by the CUSTOMER will also accommodate
                a desk top or suitable rack for installation of the system
                administrator's terminal and printer.

        (f)     Equipment Room Environment: CUSTOMER will provide adequate
                temperature and humidity equipment and controls to maintain
                optimum operation range of 40 to 100 degrees F, and 20-80%
                relative humidity. Space provided will be relatively dust-free
                and moisture-proof. The space should meet NEBS requirements for
                airborne contaminants and not contain X-ray equipment, radar or
                TV transmitters.

3.      POST WARRANTY SUPPORT CERTIFICATION
        New Communications Software generic/release/features furnished and

        Seller's then current standard rate, to determine whether modifications
        are required to make the New Communications Software conform to Seller's
        specifications and whether the New Communications Software can be
        maintained in such condition. If, in Seller's judgment, modifications

        If the Customer contracts with any party in accordance with paragraph 1
        of this Clause for its network or any site, in whole or in part, Seller
        agrees to grant such party access and use, but not a separate license to
        use such LCS, as is necessary for such party to perform its duties as
        set forth above; provided, that such party executes Seller's
        nondisclosure agreement. Customer shall give Seller ninety (90) days
        advance written notice prior to providing access and use of any LCS by

        initiation. The Severity Level of any Defect or Service call shall be
        determined by Customer; however, if during resolution Seller determines

BILLDATS(R) Data Manager Proposal
August 24, 1998
Final Revision March 16, 1999
- --------------------------------------------------------------------------------
1.0   INTRODUCTION

From new services and technology to business relationships, the world of
telecommunications becomes more expansive and comp?? every day. Successful
Service Providers and Network Operators will optimize network billing data in
near-real time to support customer care, competitive services, internal business
tools, Number Portability, wholesale/retail businesses, long distance service
and database marketing as well as other initiatives.

Telecommunications service providers must meet the regulatory and competitive
challenges of today with flexible, modular tools that enhance and build upon
existing infrastructures, processes, and diverse networks without sacrificing
future flexibility and functionality. Lucent Technologies understands that
Service Providers/Network Operators cannot afford to implement a data
collection and management solution today, that does not handle tomorrow's
services.

It is widely recognized that network data affords a rich set of customer
information that, in addition to providing billing input, offers significant
opportunities when processed by downstream applications - opportunities to
understand customers/markets better to improve service assurance processes, to
manage fraud, and to generate additional revenue.

Moving beyond the collection and transmission of billing data, the BILLDATS(R)
Data Manager capitalizes on network data for business and service management
needs. The combination of the Data Manager's highly reliable billing data
collection capabilities portfolio of standard interfaces, and Specialized
Processing Modules will allow ATG to collect call detail records and usage data
from almost any switch or network element, filter and deliver it, in
user-specified formats, to any downstream application - all in near-real time.

For example, ATG can utilize Basic Distribution (a BILLDATS(R) Data Manager
core feature) to send multiple 100% streams (10 copies on a Network Element
basis) of data to different destinations such as a second bill rendering
application, a data warehouse fraud application. Utilizing the Production
Filter Specialized Processing Module, users can filter on any field in the data
stream so as Carrier ID, Service, Calling Number, or Elapsed Time. These
files of filtered data are essentially customized "subsets" or application
specific streams of data that can be sent electronically (via Basic
Distribution) to ATG downstream applications other Service Providers, and
clearinghouses. The addition of the optional Format Conversion processing
module allows users to reform the data before it is distributed to downstream.

The BILLDATS(R) Data Manager is a highly scaleable, modular, UNIX based, open
architecture solution. Composed of "off-the-shelf" data collection, management
and distribution software application modules on one hardware platform, the
Data Manager can easily grow in functionality as ATG requirements change. The
BILLDATS(R) Data Manager application provides ATG with high speed collection
and distribution functionality. It fits into ATG's current environment without
modification, while providing the opportunity to add additional strategic
Specialized Processing Modules such as Production Filter, Production Search,
and Format Conversion either at time of purchase or at a later date. The
BILLDATS(R) Data Manager is designed to be the one flexible solution that meets
all of your needs.

Lucent Technologies welcomes the opportunity to present this proposal to ATG
for the purchase of a next generation data collect and management solution.

BILLDATS(R) Data Manager Proposal
August 24, 1998
Final Revision March 16, 1999
- --------------------------------------------------------------------------------
2.0  ATG ENVIRONMENT
The proposed ATG network environment includes:
- -  Five Lucent Technologies 5ESS switches (1999).
- -  Record volume information currently not available.
- -  Kenan Arbor BP bill rendering application.
- -  Ethernet FTP TCP/IP feed of BAF data to a single destination - Kenan billing
   entity.

Notes:
- -  Lucent Technologies assumes that the proposed Data Manager(s) will be
   deployed in full compliance with all BILLDATS(R) Data Manager
   application/interface specification documents such as the "BILLDATS(R) Data
   Manager to Downstream Application FTP Interface Specification".

- -  It is also assumed that the BILLDATS(R) Data Manager will transmit BAF data
   to the bill rendering application. If a record format other than BAF such as
   EMI is required by the biller, then the Format Specialized Processing Module
   must be purchase to map the BAF input records to a different output record
   format prior to transmission to the biller. The actual format mapping
   requirements and provisioning of the requirements in the Data Manager is
   ATG's responsibility unless BILLDATS Professional Services have been
   purchased for this work.

3.0  PROJECTED GROWTH
ATG plans to grow to 29 switches in four years (5 Lucent 5ESS switches in 1999
and 8 per year for the following three years). No volume estimates available.

The suggested Sun Ultra 2 hardware may, or may not, support all 29 IEs.
Hardware configurations are dependent on switch interfaces, selected data
management functionality, switch data volumes, and network facilities. The Sun
Ultra 2 platform can support 6 - X.25 ports or roughly 14 million records (100
byte records) polled per day, assuming switched 56K network facilities a 12
hour polling day.

              [BILLDATS(R) DATA MANAGER END-TO-END SOLUTION CHART]


                  BILLDATS(R) DATA MANAGER END-TO-END SOLUTION

The BILLDATS(R) Data Manager collects usage data from Network Elements, stores
the data as files, performs specialized processing of the data, and forwards
the usage data to one or more destination systems for bill rendering, fraud
detection, service assurance, and other applications.

The Data Manager's primary mission is to provide reliable and efficient data
collection, speedy distribution of data, and minimize operations expenses
associated with the collection of large amounts of data.

To meet growing customer needs for faster and more efficient delivery of data,
and more effective control and management of the telecommunications services,
the Data Manager offers enhanced capabilities to protect current revenues,
generate new revenue, and improve customer service, while maintaining the
reliability and performance customers have grown to expect from Lucent
Technologies BILLDATS(R) Products. The BILLDATS(R) Data Manager provides:

o    Flexible Architecture: The Data Manager fits easily into many different
     environments; wireline, wireless, intelligent network; without requiring
     changes to the existing infrastructure.

o    Convergence: The Data Manager supports simultaneous collection from many
     types of switches. A single Data Manager can be configured to
     simultaneously collect data from Local Wireline, Long Distance, Wireless,
     IP, Intelligent Network and ATM network elements.

o    Multi-vendor Environment: The Data Manager supports the
     collection/transmission of data from/to platforms from different vendors
     using different protocols and data formats.

o    Data Integrity and Reliability: The Data Manager provides polling,
     re-polling, and retransmission of data from Network Elements at the
     individual file or block level.

BILLDATA(R) Data Manager Proposal
August 24, 1998
Final Revision March 16, 1999
- --------------------------------------------------------------------------------

- -       Near Real-Time Transport of Data: The Data Manager allows the user to
        schedule all collection and transmission frequency. The Data Manager can
        support continuous polling of the Network Elements. Distribution of data
        can be scheduled as frequently as once per minute.

- -       Flexibility: The Data Manager allows the user to send data from any
        Network Element to a single destination or multiple downstream
        destinations on a demand or scheduled basis.

- -       Activity Logging: The Data Manager provides an audit trail that logs,
        among other things, files polled, files sent, commands issued and files
        cleaned up.

- -       Easy Operation: The Data Manager provides a simple, intuitive Graphical
        User Interface (GUI) for operation scheduling and control, system
        configuration, browsing reports and logs, and monitoring alarms.

- -       Hardware Scalability: The Data Manager runs on a range of platforms,
        under the powerful UNIX(TM) SVR4 operating system. This offers a range
        of processing power, storage, and communications options to meet a wide
        range of customer application requirements.

The GENERIC RECORD IDENTIFICATION (GRID) MODULE is also included in the
BILLDATS(R) Data Manager core application. GRID allows customers to specify the
input structure of records being collected, down to an individual record field
level. A single Data Manager can simultaneously support multiple GRID
definitions for various vendor's switches. The GRID Module allows the Data
Manager to parse the contents of the collected files in order to support further
processing of the records collected. The GRID module supports the definition of
multiple data formats (e.g., AMA, Ericsson Toll Ticket, EMI and Motorola DAS),
and the assignment of a data format to a particular Network Element. The data
format includes a set of record formats as well as definitions of any file
headers or trailers, and any nested block headers and trailers. Data formats can
be defined and modified by administrator using a Graphical User Interface.  When
a new Network Element is added, the administrator can either assign an existing
data format to that Network Element, or create a new or modified data format. As
data formats change, the administrator simply uses the GUI to make the necessary
changes to the record format definitions.

The GRID Module is currently available (included as part of the core Data
Manager application), and serves as a base for many of the other Specialized
Processing Modules offered to provide enhanced data management functionality.

Lucent Technologies 5ESS(R) record structure is pre-populated in the Data
Manager's GRID module by BILLDATS engineers. The population of other
(non-Lucent) record structure information in GRID is the responsibility of ATG
or the work can be purchased from Lucent Technologies as a Professional
Service.

4.2 HARDWARE

The hardware platform estimated for ATG is the Sun Ultra 2. See Attachment A
for configuration details.

Assumptions used to configure the estimated Sun Ultra 2 platform suggested in
this document:

- -       5 - Lucent Technologies 5ESS switches.

- -       ATG specific record volume information not available; used 750,000
        records per day per switch (total per day: 3.7 million) for
        configuration.

- -       100 byte average record size.

- -       AMATPS input interface.

- -       Direct Link output interface (FTP) per BILLDATS(R) Data Manager
        specifications.

- -       BAF data transmitted to a single downstream destination.

- -       Approximately 5 days of data storage.

- -       Scheduled polling.

- -       Switched 56K network facilities.

- -       10 hour polling day.

BILLDATS(R) DATA MANAGER PROPOSAL
AUGUST 24, 1998
FINAL REVISION MARCH 16, 1999
- --------------------------------------------------------------------------------
- -    The suggested hardware platform (Ultra 2) may or may not support the total
     projected ATG growth to 29 Lucent 5ESS switch over 4 years. Hardware
     platform sizing is dependent on switch interfaces, selected data management
     functionality, switch data volumes, record size, and network facilities.
     Depending on these variables, the full deployment of 29 switches may
     require a larger hardware platform.

The Sun Ultra 2 can have up to six (6) 56K X 25 ports configured (if a graphics
monitor is utilized). A fully loaded Ultra 2 platform can support approximately
14 million 100 byte records per 12 hour polling day. This figure assumes that
all ports are switched 5 and that the volume of records is fairly evenly
distributed across all switches.

Ethernet link capacity for distribution (BILLDATS(R) Direct Link) is dependent
upon bandwidth allowed to the downstream application.

A system console is provided with the base system for console access (the
suggested configuration has included a graphics terminal for this purpose).
Remote access is available through a dial up port, used for remote support.
Other access is via an x-terminal interface which can be used as an
administrative terminal to run the GUI. This terminal has no other requirements
and can be a PC equipped with an x-terminal software package.

A printer can be added to the configuration if desired; printer prices have not
been included in the suggested configuration. An optional tape drive has been
included in the configuration.

A modem for dial-in support is needed for Lucent support access (if requested
by ATG); modem prices are not included in this proposal.

Network facilities and data communication devices are not included in this
proposal and should be furnished by ATG.

5.0  ENHANCED DATA MANAGEMENT - BILLDATS(R) OPTIONAL FEATURES, INTERFACES, AND
SPECIALIZED PROCESSING MODULES

BILLDATS(R) Specialized Processing Modules (SPMs) are designed to expand upon
the billing data collection and distribution application, by adding one or more
Specialized Processing Modules to the Data Manager core application for greater
data management functionality.

Individual SPMs can be added to the proposed BILLDATS(R) Data Manager platform
as ATG's needs evolve, allowing ATG to architect or customize their own
solution effectively as budgets and business needs permit.

- -    Utilizing the PRODUCTION FILTER MODULE, customized streams of AMA data can
     be sent to multiple destinations such as billing market analysis, service
     providers and fraud applications. The user configurable filter capability
     provides ATG with the flexibility to create application specific customized
     streams of AMA data easily. The filters are applied an output, thus
     eliminating the need for storage of additional copies of the input data.
     Combined with the core Basic Distribution feature, the streams of data can
     be transmitted to multiple destinations in one minute intervals. The
     capability to perform re-transmissions and the reporting/auditing
     mechanisms allow this feature to be used in a production environment where
     this data is just as important as the primary billing feed. Production
     Filter is available now.

- -    The FILTER TEST TOOL provides the user with an interactive method for
     verifying filter criteria prior to transferring the filtered data to a
     downstream application. A customer can execute a filter application id
     against a file of records to see which records are selected by the filter.
     This allows the user to verify that the filter is working as intended prior
     to applying the filter to the output stream. Filter Test Tool is available
     now.

- -    The DATA SEARCH MODULE will locate specific records on the database meeting
     ATG's specified criteria (if chosen) in both primary and tertiary data,
     allowing ATG to accommodate client services, such as verifying test calls,
     validating new services,

     and error isolation. The search consists of identifying fields (such as
     type of service, calling number, called number, connect data, elapsed time)
     and selecting records that match the user specified values of these fields.
     The search output can be viewed at a terminal, routed to a line printer or
     sent to another application for processing. Search is available now.

 .    The BROWSER module allows the system operator to view detailed contents of
     data files using a full featured Graphical User Interface (GUI). The
     operator can select which files they wish to view, and all records and
     fields within the record can be viewed in detail. Browser is available now.

 .    The FORMAT MODULE allows the user to reformat records prior to delivering
     them to downstream applications. The Format Module allows the user to
     define multiple output record formats, define the mapping of input record
     format to output record format, and assign an output format to each
     application destination. Each destination may have a different record
     format. The mapping of input format to output format is done via a GUI.

     The Format Module allows you to convert from one record format to another
     (e.g. AMA to EMI), to normalize records (convert all records to a single,
     standardized format), to perform field extraction (e.g. include only select
     fields in a record, deleting all other fields), or convert field types
     within a record (e.g. change BCD fields to ASCII). The Format Module is
     available now.

The addition of strategic optional features would provide ATG with flexible,
competitive tools to control and manage the AMA process. These tools move
functionality such as filter, search, and format conversion closer to the
network element, decreasing dependency on the bill rendering application and
increasing ATG's ability to respond efficiently and economically to customer
requests and internal revenue processes.

 .    CONNECT: Direct input and/or output interface(s) to support the receipt of
     billing data from other service providers to the Data Manager for
     comprehensive data management - reformatting of records, filter etc. The
     CONNECT: Direct output interface supports the transmission of data to other
     providers or billing entities. CONNECT: Direct is available now.

 .    AMADNS DATA SERVER TO DPMS INTERFACE (DDI)

     Bellcore has defined a new standard for the movement of AMA data from
     generating systems to applications requiring this data. The transfer,
     processing, and management of AMA data is called AMA Data Networking and is
     provided by the AMA Data Networking System (AMADNS). The AMADNS DDI input
     interface supports billing data collection from AMADNS compliant network
     elements (Bellcore GR1343, Issue 2).


     The BILLDATS(R) Data Manager is Lucent Technologies' DPMS. As such, it
     supports an AMADNS compliant interface to a variety of Data Servers (Data
     Server functionality may be an adjunct to the switch or may be incorporated
     into the switch footprint). The AMADNS Data Server to DPMS Interface (DDI)
     is based in the TCP/IP File Transfer Protocol (FTP) and use the standard
     Ethernet LAN/WAN for connectivity.

 .    OUTPUT FILE MERGING: The Data Manager stores billing data in flat files.
     The size of each file is driven by user provisioning, near real time
     transmission is desired, then the size of each file stored on the Data
     Manager is driven by the smallest increment of data that can be collected
     from a switch and maintain data integrity. This results in a large number
     of small files. This works well for near real time transmission. However,
     for batch transmissions (such as a biller), fewer larger files is usually
     desired, output file merging feature concatenates many small files into a
     large file per network element. This allows large files to be transmitted
     to batch applications and small files to be transferred to near time
     applications.

 .    GENERIC TAPE READER to support the reading of tapes into the Data Manager
     for comprehensive billing data management. Generic Tape Reader allows a
     user to define the format of an input tape, and then read in a tape of the
     specified format. Records are read from tape, stored as files on disk, and
     can be processed and distributed in the same way as records that were
     Providers, ATG switches in the instance of a network outage etc.

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

     In emergency situations, a tape dump of billing data at a switch may be
     required. In this case, the data cannot be electronically collected by the
     Data Manager. If the Data Manager is being used for mediation, the tape of
     billing data must be read into the Data Manager. The generic tape reader
     feature allows a user to read tapes from any network element, thus solving
     this situation. The generic tape reader feature also provides a mechanism
     for reading tapes from network elements that do not have electronic
     transfer capabilities. Generic Tape Reader is available now.

- -    DISASTER RECOVERY - the intent of the Data Manager's disaster recovery
     feature is to prevent a disaster, like a fire, from completely disabling a
     customer's billing data collection and distribution environment. If a
     disaster occurs, it is accepted and handled by the customer. Billing data
     that has not been sent to all of the associated downstream applications
     may be lost depending on the nature of the disaster. However, the disaster
     recovery feature allows collection and distribution of new bill data to
     continue without interruption. The disaster is not compounded by having
     ATG scramble to determine how to continue their billing operation.

     The Data Manager's disaster recovery feature is NOT intended to provide a
     100% high availability environment. This direction was driven by the
     software complexity and monetary cost of a 100% high availability
     solution. A 100% high availability automated solution can also cause false
     triggers, switching a Data Manager's load prematurely. Our strategy is
     based on customer feedback that indicated a high preference for human
     intervention making the decision on switching the load to a backup system.

     The disaster recovery feature on the Data Manager allows "clusters" of
     Data Managers to be configured as one virtual machine. The most common
     configuration is two Data Managers in geographically separate locations.
     Each Data Manager hardware platform would be engineered to support the
     complete load. In normal operation, each Data Manager would only support
     half the load (i.e., 50-50 load share). In a disaster mode, a single Data
     Manager would support the complete load.

     Administrative information such as network element definitions (e.g., 5ESS
     switches) and billing entity definitions (e.g., downstream applications
     that receive billing data from the Data Manager; Kenan Arbor BP is an
     example of a billing entity) is stored in a relational database. The
     disaster recovery feature automatically synchronizes the administrative
     information over all Data Managers in the cluster.

     The billing data is not replicated over all Data Manager clusters (i.e.,
     each Data Manager stores its own unique copy of the billing data). If an
     individual Data Manager in a cluster fails, transmission of the unsent
     data will be delayed or lost depending on the severity of the disaster
     (i.e., hardware failure vs. a disaster like fire) following the intent of
     the disaster recovery feature.

     A single command is used to start/stop an individual Data Manager from
     entering a disaster recovery mode. Each network element and/or billing
     entity definition is assigned a "home" (i.e., the name of the Data Manager
     that supports this element in normal operation). To start/stop the
     disaster recovery mode, a manual command with the "home name" is entered.
     The manual command will cause the Data Manager to automatically start/stop
     collection and distribution of the "named" elements.

     The optional "Disaster Recovery" feature automatically replicates
     administrative database updates across all Data Managers ATG's
     environment. This allows a user to administer multiple Data Managers as
     one. It also facilitates a timely start of "recovery" mode in the event of
     a disaster. The disaster recover feature also provides one command to
     start/stop recovery on particular Data Manager. Recovery feature is
     available now.

6.0  PRODUCT DIRECTION

The BILLDATS(R) Data Manager is rapidly evolving to provide additional
capabilities for our customers. Several of the optional features and
Specialized Processing Modules available in Generic 6.0 include:

- -    THE DATA VALIDATION AND EDITING SPECIAL PROCESSING MODULES will provide the
     ability to perform a set of integrity checks based on user defined,
     pre-record, validation rules. Records which fail validation checks will
     be filtered out of the data stream. These erred records can then be edited
     by a user and reinserted into the distribution stream, deleted by a user or
     sent to a

     downstream application for further investigation. The optional Data
     Validation and Edit Modules will be available in Generic 6.0, available in
     July 1999.

o    The REPORT WRITER INTERFACE feature will provide extensive reporting
     against the usage records. The Data Manager will normalize the usage
     records, and then feed them to an adjunct Report Writer system. The
     normalized usage records will be placed in a standard database (e.g.
     Informix), where they can be queried against using standard relational
     On-Line Analytical Processing (OLAP) tools. The user will be able to
     execute ad hoc queries against the data, defining their own reports. The
     adjunct Report Writer system allows users to generate extensive reports
     without impacting the performance of the Data Manager and the feeds to
     other downstream applications. The optional Report Writer Interface feature
     will be available in Generic 6.0, available in July, 1999.

9.0 BILLDATS PROFESSIONAL SERVICES

Lucent Technologies Billing Products technical support team offers a rich
portfolio of Professional Services with a wide range of pre-defined options or
selections that are customizable to ATG specifications. Our support staff
understands the complexity of near-real time teleprocessing and data
management, and is uniquely qualified to assist ATG in achieving both their
short term and long term objectives. ATG has the option to purchase
professional services from the Billing Technical Support Team to augment their
own staff expertise. For example:

- -    GENERIC RECORD IDENTIFICATION (GRID) POPULATION

Lucent engineers will populate GRID with customer specified format information
for Specialized Processing Module administration. For the Lucent 5ESS Switch,
the GRID definitions required to support the collection and transmission of
5ESS B data is included in the core product.

- -    PROVISIONING MEDIATION CRITERIA - FORMAT

     Provisioning of mediation criteria mostly involves defining input and
     output record definition templates and logic to convert an input record to
     a record format. This effort can be performed by the customer through the
     Data Manager application GUI or it can be contracted through Lucent. If the
     customer decides to undertake this effort, Lucent will provide hours of
     consultation. If the customer wants to contract the work through Lucent, a
     flat fee will be charged to provide this effort. Lucent's provisioning
     effort will be bounded by the following:

     -    Lucent will provide all record template definitions for all Lucent
          network elements.

     -    The customer must obtain record definitions from other vendors and
          provide those to Lucent. Lucent will then provision record template
          definitions for other vendors' network elements.

     -    Lucent will work with the customer to define requirements for output
          records and the criteria to map an input record an output record ???
          format. The customer must engage other vendors to participate in this
          task if necessary.

     -    Lucent will provision and test all format mapping criteria. It is the
          customer's responsibility to provide data to test record template
          definitions and format conversions. To completely test the format
          conversions, the output produced by the Data Manager must be
          processed by the respective downstream application.

     -    Lucent will be engaged in this activity until the customer accepts
          the Data Manager system or live data is passed through the Data
          Manager. After this time, additional engineering services can be
          contracted through Lucent at d??? rate.

     -    Lucent's effort in this area only includes engineering services to
          provision record template definitions, to consult ??? defining
          formatting requirements and to provision formatting criteria. This
          effort does not include any software development activity.

Note:
BILLDATS Professional Services timelines may, or may not, coincide with the
Data Manager deployment timeline; project schedules are determined by staff
availability and the complexity of ATG requirements.

10.0 CUSTOMER ACCEPTANCE PROCESS

The Lucent Technologies BILLDATS(R) Product Team adheres to a formal customer
acceptance process. This process serves to ensure ATG's satisfaction with the
deployment, and gates the warranty period. ATG, following a set of written
procedures, activates the Data Manager processes and purchased optional
features. A formal acceptance document is jointly signed after all purchased
functionality of the product has been successfully demonstrated. The customer
acceptance process is completed after the turn-up of one Lucent 5ESS Switch
Interface in the ATG network on the Data Manager platform. The closure of the
acceptance process initiates the Data Manager software warranty period.

Sun Hardware Configuration Notes:

- -    Sun Ultra Enterprise 2 pricing shown here is U.S. List for planning
     purposes. No discount has been applied. ATG should negotiate the discount
     directly with the selected hardware vendor.

- -    Approximately 5 days of data storage provided at 3.7 million records per
     day. Data retention period can be increased by adding more disk to the
     configuration. Retention period should be finalized prior to hardware
     order. Disk space can also be impacted by utilization of the "N to 1" File
     Merging optional (billable) feature available in BILLDATS(R) Data Manager
     Release 5.5.

- -    ATG must provide hardware staging and support through Sun Microsystems
     (included with Sun suggested hardware configuration) or through the Value
     Added Re-Seller of their choice.

NOTE 1:  GRID & FORMAT CONVERSION TURN-KEY SOLUTION SERVICES

PROVISIONING MEDIATION CRITERIA

Provisioning of mediation criteria mostly involves defining input and output
record definition templates and logic to convert an input record to a record
format. This effort can be performed by the customer through the Data Manager's
application GUI or it can be contracted through Lucent. If the customer decides
to undertake this effort, Lucent will provide 80 hours of consultation.

If the customer wants to contract the work through Lucent, a flat fee will be
charged to provide this effort. Lucent's provisioning effort will be bounded by
the following:

- -  Lucent will provide all record template definitions for all Lucent network
   elements.

- -  The customer must obtain record definitions from other vendors and provide
   those to Lucent. Lucent will then provision record template definitions for
   other vendors' network elements.

- -  Lucent will work with the customer to define requirements for output records
   and the criteria to map an input record to an output record format. The
   customer must engage other vendors to participate in this task if necessary.

- -  Lucent will provision and test all format mapping criteria. It is the
   customer's responsibility to provide data to test the record template
   definitions and format conversions. The completely test the format
   conversions, the output data produced by the Data Manager must be processed
   by the respective downstream application.

- -  Lucent will be engaged in this activity until the customer accepts the Data
   Manager system or live data is passing thru the Data Manager. After this
   time, additional engineering services can be contracted through Lucent at
   daily rate [*]

- -  Lucent's effort in this area only includes engineering services to provision
   record template definitions, to consult on defining formatting requirements
   and to provision formatting criteria. This effort does not include any
   software development activity.

Pricing and other critical elements of Statements of Work provided by Lucent to
ATG are based upon the binding, non-conflicting terms and conditions of Letter
of Intent ("LOI") between Advanced Telecom Group, Inc. ("ATG") and Lucent
Technologies Inc. ("Lucent"). This LOI is incorporated herein by reference and
shall be extended until the earlier of written termination by either party in
accordance with Section 3.3 of the LOI or execution of the definitive agreement
described therein. If at the time such definitive agreement is executed
Services under Statements of work are ongoing, the definitive agreement shall
supersede any non-conflicting terms and conditions for such Services. Lucent,
acting through its Global Services Provider Group, will perform and ATG will
procure the Services described in this Statement of Work ("SOW"). By ordering
or using these Services from Lucent, including changes or additional orders,
ATG agrees to be bound to the terms of this SOW. Lucent reserves the ability to
make amendments prior to execution of this SOW, if changes in scope make such
amendments advisable and as agreed by ATG. During the SOW term, changes to this
SOW which are generally available to other Lucent customers will only be made
through the Change Control Process as stated in Section 3, unless otherwise
mutually agreed in writing. Please reference the applicable SOW by title and
number on any order or correspondence to Lucent.

1    Statement of Work
- --------------------------------------------------------------------------------

In order to meet ATG's operational milestones and provide Services to ATG as
described in Section 3.6, "Network Operations Services" of the LOI, Lucent will
perform Phase Two of the Operations Planning Services at its Network
Reliability Center located in Aurora, Colorado ("NRC"). In consideration for
the pricing set forth herein, ATG agrees to procure and Lucent agrees to provide

providing these Services.

This SOW supersedes both the deliverables and remaining unspent dollars
identified in Exhibit G Section 3 "Operations Planning & Implementation"
Sub-Section 3.3 "PHASE TWO: FUTURE METHOD OF OPERATIONS." While this SOW has
attempted to capture all of the relevant deliverables for the IMO, there may
have been an unintentional oversight of required analysis that will not be
deemed a Change order. Such oversight shall be treated as a Change under the
Change Control Process described in Section 3 to determine whether this Change
is an oversight, a Change to an existing order, or an out-of-scope request to
be quoted prior to rendering the service.

5    CUSTOMER REQUIREMENTS / CONNECTIVITY - SERVICE ACTIVATION

The NRC will start customer service activities upon establishing and certifying
connectivity between the required NRC operations support systems and customer
provided central office and transport equipment. Once the T1 Frame Relay
Network is in place, tested, and connected to the customer's host switch and
transport network elements (NE), the NRC operations team will begin providing
customer requested services. At this point in the process the monthly
connection charges to the customer begin. The following steps are involved in
providing a reliable network.

NOTE - CONNECTIVITY / SERVICE ACTIVATION IS A 60 DAY PROCESS. ALL REQUIREMENTS
FOR CUSTOMER INFORMATION MUST BE RECEIVED BY THE NRC prior to the placement of
the circuit order in order to meet the customer's time to market requirements.

STEP #1 Obtaining The Latest Site Configurations

STEP #2 Establishing Customer Connectivity

STEP #3 Responsibility Matrix

5.1  OBTAINING THE LATEST SITE CONFIGURATIONS/GROWTH
- --------------------------------------------------------------------------------

All work performed by the NRC will be based upon the latest site
configurations. Any configuration changes must be provided to the NRC in
writing and are subject to engineering and pricing reviews to ensure capacity
availability. If the NRC has an existing router capacity at the customer host
site and at the Denver NRC to support the addition of a new element, then only
the one time new element connectivity fee will be charged. If the NRC does not
have enough router capacity at the customer site or the Denver NRC location the
new element and element connectivity fees will be quoted separate from the final
statement of work. Please allow up to three weeks to connect a new network
element, if the NRC has existing capacity.

The customer will be responsible to provide the 5ESS switch packs and cables to
support their desired services as described in Table A.

o The NRC requires growing all ports below during the Engineering and Design
  phase.

5.2  ESTABLISHING CUSTOMER CONNECTIVITY

- --------------------------------------------------------------------------------
Lucent will order, install, test, and maintain Frame Relay and ISDN backup
circuits along with their associated equipment for each customer location. The
NRC, will direct its network provider to have the local exchange company (LEC)
install the Frame Relay and ISDN circuits at the customer provided LEC
demarcation point. The circuit will be extended from the demarcation point to
the dataset cabinet by a Lucent Technician. Circuits will be ordered when: the
full site address location; phone number; and on-site customer contact
information is provided to the NRC, (see customer responsibilities below). Upon
placement of the circuits and after ensuring that the pre-installation and
certification criteria is met, the NRC will dispatch a connectivity
installation team. The connectivity installation team will install, test and
turn-up all required Frame Relay and ISDN equipment. Upon completing the work
at the customer site, additional work and testing will be completed at the
Denver NRC site. This work includes connecting the circuits to the required
Operations Support Systems and making the necessary database configuration
settings. The NRC will establish an ISDN backup circuit that will ensure NRC
visibility of the customer network elements if the primary link is not
operational. The connectivity drawing below outlines a typical NRC to customer
site circuit configuration. The actual equipment used and network elements
connected to the NRC

6    NETWORK MONITORING & SURVEILLANCE

Lucent Technologies' Remote Monitoring and Surveillance Services will be
provided based on the Service package chosen by Customer. Remote Surveillance
capabilities for monitoring Customer's network, including all associated
Supplier network elements (excluding any non-Supplier network elements, which
must be approved in writing by the Lucent Technologies NRC prior to initiating
Monitoring Services). Monitored conditions will include Service interruptions,
alarm reporting, system outages, call processing loss, initializations, and
duplex hardware failures. Problems may be addressed and resolved remotely or
on-site, or trouble notifications may be provided to Supplier and/or Customer-
specified personnel for resolution.

6.1  COMPONENT SERVICES

     o    Alarm Testing. Critical, major, minor and fuse alarm status
          indicators are tested on an agreed upon basis not to exceed one (1)
          time each Term year. Environmental alarm conditions are monitored on
          an on-going basis.

     o    Alarm Resolution. The NRC will initiate corrective action in response
          to critical, major, and minor alarm conditions identified during
          remote and/or on-site surveillance periods.

     o    Trunk Maintenance. The NRC will respond to switch, customer, and
          repair Service-reported trunk problems.

     o    Escalation and Resolution of Network Problems. The NRC will initiate
          corrective action in response to any alarm condition. In line with
          Customer-specific escalation plans, unresolved problems will be
          escalated to the appropriate Lucent Technologies Technical Assistance
          organization as necessary, including Bell Laboratories. When Customer
          has selected Lucent Technologies for Case Management of each problem,
          the NRC will retain ownership of the problem through resolution.

     o    Software Updates. Supplier plans to correct generic program software
          problems and provide feature enhancements in Customer's network system
          and maintain associated history logs.

     o    Emergency Recovery Procedures. If Customer's 5ESS(R)-2000 switch is
          unable to automatically recover from fault conditions or
          initializations, Supplier will deploy manual procedures to clear
          failures, restore operation, and minimize Service interruptions.

     o    Dispatch of On-Site Technical Personnel. Depending on Customer's
          selection of on-site support, Supplier can dispatch designated
          technical personnel to the affected site to resolve hardware problems.

     o    Alarm and Service Outage Analysis. The NRC will conduct root-cause
          analysis of system initializations, maintenance interrupts, major
          alarms, and software and hardware failures, utilizing chronological
          data of system activity to assist in avoiding similar recurrences of
          system failures. These root-cause analysis reports will be limited to
          Severity levels which result in a loss of call processing. Lucent

                               Exhibit G - 28 of 47

     Technologies will be responsible for determining the extent and frequency
     of the analysis.

o    Diagnostic Failures. Routine automatic and manual diagnostic procedures
     will be conducted to detect 5ESS(R)-2000 switching hardware faults.

o    Memory Administration. The NRC will monitor Customer's network to ensure
     that adequate memory capacity is available for system operation.

If the NRC identifies the need for an on-site dispatch and Customer has
arranged for third party on-site coverage, the NRC will direct the dispatch to
Customer's help desk or other mutually agreed-upon central source.

The current Escalation criteria documented below may be modified to meet
Customer's expectations. A detailed Customer internal escalation process will
be established to ensure that Customer personnel are properly notified in the
event of a Service-affecting activity.

6.2  NRC STANDARD ESCALATION GUIDELINES

7    NETWORK PERFORMANCE SERVICES

     Network Performance Services will consist of six component Services
     essential to Customer's ability to manage the investment in their network
     and to maximize their service to end-users and/or resellers.

7.1  TRAFFIC DATA COLLECTION
- --------------------------------------------------------------------------------
     This Service provides the collection of real time traffic data from network
     elements and related facilities within the network Collection of data will
     be on 5ESS(R)-2000 switch components, trunk groups, and 5ESS(R)-2000 switch
     performance.

     Traffic Data Collection includes:

     o    Connectivity and scheduling
     o    Establishing thresholds
     o    Time consistent and true busy hour reports
     o    Exception reports based on threshold items
     o    Exception report analysis
     o    Data retention - 45 days of raw data, 13 months of summarized data
          (on-line), 5 years of summarized data (off line)


7.2  CAPACITY MANAGEMENT
- --------------------------------------------------------------------------------
     The NRC will perform capacity management on Customer's networks. Using
     data collected, weekly and monthly reports will be generated as follows:

     o    Switch Performance
     o    Switch Components
     o    Trunk Groups
     o    Threshold Exception Trending
     o    Memory Administration

     Supplier will analyze note recommendations and items requiring attention on
     the monthly reports sent to Customer.


7.3  NETWORK MANAGEMENT
- --------------------------------------------------------------------------------
     The NRC will use real-time surveillance and monitoring of message traffic
     (5 minute data) to allow for network control capabilities and for the
     patterning of network call irregularities. The systems will use manual and
     automatic/dynamic control capabilities to maximize call-carrying capacity
     and to interact with the network to minimize the adverse effects of traffic
     overloads and disaster situations such as switch, signaling or facility
     failures.

7.4  SPECIAL STUDIES
- --------------------------------------------------------------------------------

     Special Studies deliverables fall into two categories - Customer and
     Equipment/Network

     Customer Special Studies includes data on a particular customer group such
     as Single Line, Series Complete, MLHG, SFG, or customer TGN. This data will
     be a one week study that will include graphical as well as summarized data
     by hour for a specific customer. The data includes peg count, overflow,
     usage and grade of service recommendations. This data includes both peak
     and time consistent busy hour. These studies can be used for internal
     administration as well as marketing data for Customer sales teams.

     The Equipment/Network Special Studies includes any study that is not part
     of the normal capacity monitoring package, such as studies on TR008/TR303
     Remote Terminals, specific type or group of switch peripherals, and special
     switch interactions.


7.5  D & F SERVICES
- --------------------------------------------------------------------------------

     Planning, designing and engineering the configuration of the network is a
     multifaceted discipline. Supplier will provide information on installed and
     working components of Supplier equipment to enable Customer to utilize the
     engineered capacity and plan for timely relief.

     The NRC's D & F (Demand and Facility) Service will provide the following
     information to enable Customer to properly administer and plan for timely
     relief:

     o    Develop Demand and Facility (Capacity) charts for port limited switch
          components. These components include:

          DNU-S
          IDCU
          DCS

     This Service complements the information provided on traffic sensitive
     components in the Capacity Management Services offering.

     This information will be provided on a monthly basis. Additional components
     will be provided as part of the network special study category of the SOW.

7.6  NETWORK RELIEF PLANNING
- --------------------------------------------------------------------------------

     The NRC's goal in providing Relief Planning Services is to determine the
amount of equipment required to meet the increased end-user service demands in
a timely fashion while minimizing Customer's total network costs. This Service
is provided as an additional offering to those customers who have subscribed
to the D & F Services and Capacity Management Services.



- --------------------------------------------------------------------------------
                              Exhibit G - 34 of 47







<PAGE>   177
EXHIBIT G

To accomplish this:

o    Supplier and customer will jointly develop the thresholds (75%, 85%, etc.)
     at which time a relief job will be triggered or recommended. The size of
     switch addition will be based either on historical trends and/or customer
     forecast as well as agreed upon relief interval.

o    Depending on the agreed upon process/procedure, customer can be provided
     with a recommendation of equipment to be ordered or even a TEO to be
     reviewed, approved and ordered by Customer:

Combined with Capacity Management Services and D & F Services, this Service will
allow Customer to effectively and efficiently manage its capital investments
while continuing to meet the demands of its end-users while offering a specific
grade of service to end-user customers.

10   TROUBLE MANAGEMENT SUPPORT

All information in this section is contingent upon Customer obtaining and being
responsible for all interface agreements, negotiations and execution of the
definitive agreements with all other service providers with whom the NRC will
communicate on behalf of Customer. Customer is also responsible for providing
all necessary system interfaces between Customer's order management offices and
the NRC.

Total time charged to a trouble ticket is based on the entire process, from
initial trouble ticket receipt throughout the duration processing, testing, and
resolution time of the ticket. Any trouble tickets received as an Escalated
request will be billed at no less than a two (2) hour increment. There will be a
pre-approval list of names provided by Customer of who can escalate a trouble
ticket. All Escalated trouble tickets must be accompanied by a signed approval
for the Escalation. Supplier's NRC will, in every case, treat each trouble
ticket with the utmost importance. Each trouble ticket will be logged and
processed as soon as it is received by the NRC Trouble Management personnel.

ADSL Service Assurance (or Maintenance Testing) is process of performing tests
on a line when a customer calls in with a trouble, or if there is trouble noted
by the Monitoring & Surveillance group. The objective of such testing is to
isolate trouble so that the proper repair personnel can be dispatched to the
correct location with the appropriate equipment. The objective of ADSL service
assurance is to provide this level of detail automatically in a manner similar
to that done currently for POTS and ISDN services. Unlike special services
testing, the tester is not required to know the details of the test process or
the interconnections which makes it appropriate choice for automation and
flow-through processes.

The ADSL signature detection feature and the ADSL wideband access and test
features are also appropriate to the service assurance process. Together with
the digital testing capabilities (described next) and the enhanced narrowband
test capabilities (such as load coil detection), they provide a complete
solution for ADSL Service assurance.

10.1 CUSTOMER CARE SUPPORT
- ------------------------------------------------------------------------------
     Supplier shall provide Around-the-Clock (also referred to as "7 x 24")
     Customer Care Support Service to Customer and Customer's end-user
     customers via a toll-free access line for problem and trouble reporting.

     o    At Customer's request, Supplier shall answer calls in the name of
          "Advanced TelCom Group, Inc."

     o    Caller data will be validated for purposes of entitlement.

     o    For ISP trouble calls, only Tier 1 support will be provided. Tier 1
          support is defined as receipt of trouble calls, screening of the
          trouble based on a script provided by ATG and transfer of the call to
          the ATG ISP technical services group if the trouble cannot be
          resolved using the script.

          Customer's organization (as contractually agreed).

     o    On-Site dispatch, when required, will be scheduled in accordance with
          customer's on-site coverage parameters.

     o    Trouble Ticket Database Management. NRC personnel will create, track,
          and retain all pertinent data associated with each trouble and/or
          inquiry. Such database is summarized monthly and a report is generated
          highlighting call volume, failure data, resolution times, and type of
          inquiry. Monthly activity reports will be made available to Customer.

     o    Customer Notification. For each technical trouble or network
          malfunction, current status, call completion, and trouble resolution
          information will be provided to Customer, either on a scheduled daily
          basis, or in accordance with documented and mutually agreed-upon

          source (including third party vendors) for resolution and/or
          disposition. In line with this offering, the NRC will retain ownership
          of each problem through the resolution process. Current status, call
          completion, and trouble resolution information will be provided to
          Customer, either on a scheduled basis, or as documented in formal
          escalation and notification plans. Response and service level

                            GENERAL SUPPLY AGREEMENT

                     STATEMENT OF WORK FOR ORDER MANAGEMENT


1. STATEMENT OF WORK

Lucent Network Reliability Center (NRC) will provide an Order Management
function for Advanced TelCom Group, Inc. (ATG) utilizing both the Digital
Counterpart Inc. (DCI) eC.Order product along with newly created or existing NRC
manual processes. This Order Management System is intended to be for an interim
period only; pending general availability of a completely mechanized order
management system, Lucent NRC will manage orders using a mixture of manual and
automated processes. Order Management will provide the capability to complete
and track a service order and perform the work necessary to put an ATG end-user
customer into voice and/or data service. Order Management will include order
management functionality described below:

        -   Ordering unbundled loops from the ILECs (e.g., Pacific Bell and US
            West);

        -   Local Number Portability (Interface to Illuminet and switch
            provisioning);

        -   5ESS-2000 switch provisioning (Lucent 5ESS-2000 and AnyMedia FAST);

        -   SONET electronics and digital cross connect provisioning (Cerent);

        -   Provisioning of Internet/xDSL services ( Nokia/Diamond Lane and
            various selected xDSL CPE suppliers);

        -   Interface with ATG INOC for ATM routing (Cisco), Modem Pooling (Port
            Master IV) and ATM-to-TR-303 Conversion (Jetstream);

        -   Interface for long distance provisioning (Qwest and other DBAs);

        -   Calling Card Fulfillment interface;

        -   Voice and Fax Messaging interface (Octel MCS);

        -   E911 interface (SCC Communications);

        -   LIDB interface (Illuminet);

        -   All physical and logical inventories, including network transport,
            to support provisioning and capacity planning functions above;

        -   Providing order status back to the Order Creation system (eC.Order);

        -   Notification of order completion to ATG to initiate billing (Arbor
            BP).


2. ORDER MANAGEMENT PROCESS FLOWS

See Attachment of written and graphical representations.

3. REPORTING PROCESS

ATG will receive daily and weekly performance reports for the first thirty (30)
business days from the Lucent NRC that will quantify actual time spent for each
task on a daily basis as required for the Order Management process for each
service performed. These performance reports will also include the specific work
performed and who performed the work. Further, summary reports will provide the
number of minimum billing increments (15 minutes) plus total cumulative hours
consumed for each type of work. Upon consuming the first thirty (30) business
days worth of hours, the NRC and ATG will continue tracking hours in this same
manner until such time as ATG and NRC can agree to convert, with sufficient data
collected during the first


<PAGE>   190

thirty (30) business days to develop metrics allowing such change, to a fixed
fee, transaction based pricing model.

4. SCHEDULE AND FEES

Lucent's NRC will start the Order Management process on July 1, 1999 and
continue using the above noted reporting process for thirty (30) business days
or until a fixed-fee, transaction based pricing model is agreed to or for no
more than ninety (90) business days. It is hoped that by no later than September
1999, the process will be reviewed and from data compiled, transition to a more
mechanized and transaction-based process and pricing model.

The price for this service starting July 1, 1999 is to be based on a [*] per
hour fee for each resource with a cap of five hundred (500) total hours [*]. ATG
will issue a purchase order for this amount, Lucent will immediately issue an
invoice upon receipt of purchase order (due via fax within two (2) business
days), and ATG will remit payment on net thirty (30) day terms. ATG agrees to
issue subsequent purchase orders for similar amounts (based on previous month's
history) for each following monthly period or until the transaction based
pricing model is implemented. Billing will be calculated in 15-minute increments
or multiples of 15-minute increments. The goal is to match daily, weekly,
monthly reporting detail with each invoice.

Please indicate ATG's acceptance of this SOW by sending an e-mail message to the
Lucent Offer Manager, Neil Gembrin, at [email protected] stating your
acceptance or by signing below and faxing this SOW to (925) 468-3509.

       HIGH-LEVEL FACILITIES-BASED CUSTOMER SERVICE FULFILLMENT PROCESS



This narrative describes the steps outlined in the accompanying flowchart.

1.1  PRE-SALE CHECKLIST PROCESS

Sales will gather information for the customer as they do in resale. There
will be different sales package for facilities that will require additional
information based upon the services ordered. Telephone numbers will be assigned
from an available inventory at this stage. Requests for vanity numbers may be
addressed with the Telephone Number Inventory administrator. Requests by Sales
to override the standard equipment configuration for an order will be
negotiated with Engineering.

1.2  SALES PACKAGE

The completed sales package will be sent to the Customer Service organization
where it will be entered into eC.Order by the CSR.

1.3  PROVISIONING

The order will be sent from eC.Order to the Lucent NRC for fulfillment. The
NRC will update the status of the order in eC.Order so that it can be viewed by
the CSR. If there are errors on the order or insufficient information to
complete the order it will be referred back to the Customer Service organization
(with error reason) for correction/completion.

If the promised delivery timeframe cannot be met or the requested equipment is
not available, the order will be referred back with a jeopardy code.

Once the order is completed, eC.Order will pass data to Kenan to initiate (or
change or stop) customer billing.

1.4  EXTERNAL SYSTEMS INTERFACE

The NRC will handle all of the external interfaces necessary to provision an
order with the exception of Directory Listings that will be handled by the
Customer Service Organization in each Branch.

1.4.1     E911 -- For emergency location of customers (via SCC)

1.4.2     LNP -- Local Number Portability for transferring numbers from one
          carrier to another (via Illuminet)

1.4.3     LIDB -- For authorization of 3rd party calls etc. (via Illuminet)


                                                                               1

<PAGE>   193
1.4.4     Octel -- For VoiceMail

1.4.5     Qwest -- For Long Distance Service

1.4.6     Other IXC PIC Care -- For customers who select a different long
          distance carrier than ATG.

1.5  EQUIPMENT PROVISIONING

This covers the assignment of all the physical equipment necessary to provision
an order.

1.5.1     LOOP ASSIGNMENT

The NRC will order the unbundled loop from the ILEC (if necessary).

1.5.2     TRANSLATIONS

The NRC will perform the switch translations for this order.

1.5.3     TRANSPORT

The NRC will provision all of the transport equipment needed for the order
(Diamond Lane, Pairgain, etc.)

1.5.3     TEST & TURN-UP

The NRC will notify the Local Field Organization if they have to perform work
to turn-up the customer's service and will coordinate testing. The LFO will
perform the work at the customers location including the installation of any
required CPE.

1.6  SUPPLEMENTS FOR DD CHANGE, CANCEL, OTHER

Supplements may be issued against the order if there is a change in the due
date or the order is canceled.

          all times remain one of independent contractors and shall not create
          the relationship of franchisor and franchisee, joint venturer or
          principal and agent. Buyer shall not have authority to assume or
          create obligations on Lucent's behalf with respect to the Products,
          Licensed Materials, or Services furnished by Lucent hereunder or
          otherwise, and Buyer shall not take any action which has the effect
          of creating the appearance of having such authority. Buyer has not
          paid Lucent any fee in consideration of this Agreement.
     b.   All persons furnished by Buyer shall be considered solely Buyer's
          employees or agents, and Buyer shall be responsible for payment of
          all unemployment, Social Security and other payroll taxes including
          contributions from them when required by law.

     c.   Buyer agrees that it has no exclusive right to use of Indicia as
          defined herein in any geographical area or for any product identified
          herein. Lucent expressly reserves the right to contract with others
          to promote, market, sell and/or install Products, to use the Indicia
          and to permit others to engage in such activities at any time and in
          any place.

5.   Use of Marks

     The use of Lucent's tradenames, trademarks, trade devices, logos, codes,
Co-Marketing Brand and logo or other symbols (collectively "Indicia") shall be
solely for the purpose of and in the manner permitted by the Program
Documentation. Lucent hereby grants Buyer permission to use Indicia in Buyer's
marketing and advertising of, and in Buyer's publicity relating to, the Products
and Agreements identified in Program Documentation, PROVIDED such use conforms
to Lucent standards and guidelines contained in the Program Documentation which
Lucent may furnish from time to time. Without limiting the terms of such Program
Documentation, the



                                  Page 2 of 8
<PAGE>   196
following shall also apply: (1) Buyer may not conduct business under Lucent's
name or logo; (2) Buyer may not use any of Lucent's Indicia or variations
thereof to identify Buyer or Buyer's products or services except as
specifically permitted by the Lucent's Co-Marketing Program Office identified
in the Program Documentation; and (3) Buyer may not use any of Lucent's Indicia
in a manner that is likely to confuse the public concerning the relationship of
the parties. Buyer's use of Indicia shall inure to the benefit of Lucent and
shall not invest in Buyer any rights in or to the Indicia. All users of Indicia
by Buyer shall be subject to prepublication or pre-use review and written
approval buy Lucent. If, in Lucent's judgment, any use of Indicia by Buyer is
deemed detrimental to the Indicia or Lucent's reputation, or is deemed
otherwise undesirable, Lucent may withdraw such permission without liability as
a result thereof.

6.   Confidentiality of Information

     Buyer and Lucent shall, except to allow Buyer to represent itself to the
public in accordance with the Program or as otherwise agreed in writing, keep
this Agreement and all Program Documentation confidential. Where mandated by
law, this Agreement may be disclosed to any court or legislative body or filed
with, or disclosed to, any governmental organization or agency, in which case
the party making the disclosure shall promptly inform the other of such
disclosure and the disclosing party shall, at the request of the other party,
take all reasonable steps to preserve the confidential nature of this Agreement
and its contents including, without limitation, seeking to obtain a protective
order or similar confidential treatment.

7.   Infringement

     a.   Lucent will defend all suits against Buyer alleging that any Indicia
          furnished hereunder infringes any United States patent, or United
          States trademark, and will pay direct damages and costs which, by
          final judgments, are awarded against Buyer on account of such
          infringement, provided that:

               i.)  Lucent has been given prompt written notice of all claims
                    of such infringement and suits by Buyer and the full
                    opportunity and authority in the name of the Buyer or
                    otherwise to assume the sole defense of and to settle or
                    compromise such suits;

              ii.)  Lucent has been furnished by Buyer, upon request, all
                    information and assistance available to the Buyer for such
                    defense, including abstention from making any admissions to
                    claimant regarding the claim; and

             iii.)  Lucent's responsibility hereunder shall not exceed the
                    purchase price of the allegedly infringed items.

     b.   If any item in such suit is held to constitute infringement and the
          use of said Indicia is enjoined, or in Lucent's opinion is likely to
          be enjoined, Lucent will, at its sole option, either:

               i.)  replace the Indicia with a non-infringing one;

              ii.)  procure for Buyer the right to continue using said Indicia;

             iii.)  modify the Indicia so that it becomes non-infringing; or,



                                  Page 3 of 8
<PAGE>   197
          iv.) remove the Indicia.

     c.   The obligation set forth in this Paragraph 7 shall not apply to the
extent that such infringement arises from:

          i.)  Lucent's adherence to specifications or drawings supplied by
               Buyer; or

          ii.) the sale or use of any item not supplied or specified by Lucent
               in combination with product supplied by Lucent

THE FOREGOING STATES THE ENTIRE LIABILITY OF LUCENT FOR PATENT OR TRADEMARK
INFRINGEMENT BY ANY INDICIA.

<PAGE>   199

1 EXECUTIVE SUMMARY

1.1 OBJECTIVE OF THE OPERATIONAL READINESS PLAN

Advanced TelCom Group, Inc. (ATG) has contracted with Lucent Technologies
Professional Services to provide a full range of Network Reliability Center
(NRC) services. These services include a team of professionals to work with ATG
management to develop an Operational Readiness Plan. The Operational Readiness
Plan collects valuable information, performs some analysis and serves as a
useful document to assist ATG management with the successful implementation of
their entry into offering communications services.

Initially, these service offerings will be provided by ATG in three markets. At
start-up in April of this year, ATG will resell Incumbent Local Exchange Carrier
(ILEC) services to its customers and dial-up internet service. Later in the
year, ATG will implement their own network and will be offering the following
services:

                  -        Local phone service
                  -        Long distance phone service
                  -        Voice mail
                  -        Packet-Switched services
                           -        XDSL
                           -        Dial-up
                           -        Web hosting
                           -        Etc.

ATG is also investigating other services that may be offered over their network
including video-on-demand.

The three phases that the Operational Readiness Plan encompasses are:

        -       Business Objective Analysis (BOA)

        -       Present Method of Operation (PMO): describes the resale and
                initial ISP phase of the business

        -       Future Method of Operations (FMO): describes the
                facilities-based ATG network

This document describes the BOA phase of the Operational Readiness Planning
project.

                 [OPERATIONAL READINESS PLANNING PROCESS CHART]





        1.      A Business Objective Analysis (BOA). The BOA is the first step
                in the Operational Readiness Plan. The BOA provides an analysis
                of corporate objectives and strategic directions as they have
                been understood by ATG's management team. The BOA is part of the
                Operational Readiness Plan and as such is not an independent
                document that defines strategies, planning or specific actions.

        2.      A Present Method of Operation (PMO). As the second step in the
                Operational Readiness Plan, Lucent will develop process models
                that describe the way ATG will be doing business in the Resale
                phase of their business

        3.      A Future Method of Operations (FMO). As a third component of the
                Operational Readiness Plan, Lucent will deliver to ATG a
                document which: (1) will analyze the gaps between the Present
                Method of Operations and where ATG wishes to be after the
                implementation of the Lucent network; (2) documents ATG's
                business processes in the Facilities-based environment; and (3)
                may make recommendations to improve the efficiency and
                effectiveness of ATG's business operations.

1.2 OBJECTIVE OF THE BUSINESS OBJECTIVE ANALYSIS (BOA) PHASE

The intent of this phase is to understand and document ATG's day-to-day and
strategic directions. Both these long-term and short-term business perspectives
(i.e., goals, objectives, critical success factors and problems) will be used to
prioritize and guide the development of the Future Method of Operations model
that will support the implementation of the Facilities-based environment. The
information contained in this document was gathered in a series of interviews
conducted with



         Advanced TelCom Group, Inc. - Confidential and Proprietary       Page 2
<PAGE>   208

ATG executives and managers. The information obtained in the interviews was then
analyzed and the models described below were produced. Dan Cruz guided the BOA
team in determining the list of interviewees and was responsible for reviewing
early drafts of this document.

1.3 BARRIERS TO SUCCESS

During the interview process and based upon the observations and analysis of the
BOA team, there are a number of critical issues that have not been addressed or
do not seem to be receiving the appropriate level of attention.

Revenue Assurance - ATG needs to be able to reconcile what it is paying for vs.
what it is billing for. This includes unbundled loops from the ILECs, LD usage,
etc. This will be almost impossible to do manually and will require a dedicated
resource with support from appropriate information systems.

Inventory - In discussions of inventory between ATG and the NRC, no request was
made to maintain a physical inventory of equipment (model numbers, serial
numbers, location, etc.) This will become an especially serious issue if ATG
starts providing CPE (e.g. xDSL modems).

Telemarketing - The stated strategy is that those customers with 1 -3 business
lines will be telemarketed. No one in the organization appears to have decided
whether this will be done internally or outsourced.

Quality and Service - ATG is pursuing a differentiation strategy based on
quality and service over price. Specific instances include short provisioning
intervals, accuracy (orders, bills) and superior customer service. However those
things that will provide quality and service such as information systems are not
in place. This compounded by the aggressive implementation schedule. This could
be overcome by hiring a large number of staff, but this is both difficult and
contrary to ATG's goal of minimizing the number of in-house staff.

ISP Marketing Strategy - There seems to be some confusion over the marketing
strategy for Packet-switched services. The initial roll-out is going to be
dial-up access at 56k. This would seem to attract the residential rather than
the business customer. Will ATG be selling to business-only or business and
residence customers? Also, there is uncertainty across the organization about
how service is being sold - will the same sales force be used as for telephony
or will there be a dedicated sales force?

ISP Support - Since ATG has made the decision to enter the dial-up ISP market,
it is possible that the company will attract a large customer base. In this case
there is the potential for a high volume of inquiry and trouble calls. Although
the Lucent NRC is providing Tier 1 support, many call swill still have to be
fielded by ATG. There is unlikely to be a sufficiently large staff in place to
handle these calls effectively. This could lead to significant customer service
issues.

Service Intervals - There do not deem to be any predefined intervals for how
long it will take to provide service to a customer. The sales force will need to
make a commitment to the customer as to when their ATG service will start,
especially for customers that do not currently have ILEC service.

No predefined metrics - Most managers felt that metrics would be developed later
from actual results. An initial set of measurements should be defined and
captured. These can be refined as



         Advanced TelCom Group, Inc. - Confidential and Proprietary       Page 3
<PAGE>   209

the business matures. If no metrics are in place it is impossible to tell how
well a job is being performed or to measure improvement.

Absence of Key Executives - ATG is at a critical stage in developing its
business, organizational and operational business model. However, at least two
critical executive positions are not in place. A Chief Operating Officer should
be overseeing the development and implementation of operating practices and
procedures. A Chief Financial Officer should be taking the lead on revenue
assurance and other finance-related matters.

1.4 CONCLUSIONS

As described in more detail in the rest of this document, ATG has adopted a
combination of market niching and product and service differentiation strategies
to support the primary goal of becoming the number one CLEC in Tier 3 and Tier 4
markets. The company has a lot of strengths, especially in the experience and
contacts that the senior management team brings to the table. Thorough market
research and a local focus are other areas that can help ATG be a success.

This analysis identified a number of problems that could hinder ATG's success
that are not being addressed by ATG's current strategies. The most immediate of
these are:

(1) THE DIFFICULTY OF ATTRACTING AND RETAINING THE NUMBER AND QUALITY OF STAFF
needed to meet ATG's aggressive expansion plans. This is particularly true in
the areas of technical staff (e.g. 5ESS technicians), sales (people with both
local knowledge and technical expertise) and General Managers (assuming that the
Brooks pipeline of proven talent is tapped out). This problem can be attributed
to a number of factors including the smaller labor pool in smaller cities and a
general shortage of many of these kinds of resources. This problem is difficult
to overcome but could be ameliorated by an extensive and comprehensive internal
training program.

(2) THE ONGOING RELIANCE OF ATG ON THE INCUMBENT CARRIERS. The foundation of
ATG's business rests with ILEC facilities for the "final mile". ATG's ability to
offer quality service in a timely fashion is totally dependent upon the ILEC's
willingness to provide timely access to their facilities, co-location space and
speedy resolution of problems. This could be partially addressed by seeking new
technological solutions to providing access such as LMDS. In the short term it
is essential to keep comprehensive records of ILEC performance to ascertain
compliance to interconnect agreements and regulations.

(3) THE LACK OF BUSINESS AND OPERATIONS SUPPORT SYSTEMS. Quality customer
service, speed of provisioning and convergent billing are all part of ATG's
differentiation strategy. These are almost impossible to achieve without the
support of robust, flexible OSSs. This will become especially apparent if the
business grows as rapidly as predicted. This is being addressed to a high degree
by partnerships with AMS and Lucent.

2 VALUE CHAIN ANALYSIS

A company's value chain consists of the key activities or functions that it
performs that add value to the product and services the company brings to the
marketplace. An understanding of ATG's value chain can help determine which
functions of the organization give it a competitive edge in the marketplace. It
can also indicate how to maximize ATG's competitive ability by introducing new
technology to support the functions that make up ATG's value chain.

Function analysis is especially important given the entrepreneurial nature of
ATG. As an entrepreneurial company, the organizational structure is always in
flux and the company operates without a formal chain of command. Rather people
step into the breach and take on duties as the need arises. It is therefore more
helpful to analyze what is done (functions performed) rather than the
organizational structure of ATG.

The Value Chain Analysis highlighted eleven functions that are central to ATG
delivering its products and services to its customers. The value chain model
describes two major categories of functions or activities that a company
performs to provide value to its customers:

PRIMARY FUNCTIONS are the key functions that are directly related to the
production and delivery of products and services. For ATG, there are six primary
functions:

1.      SERVICE ACQUISITION - this includes acquiring components of ATG's
        service offerings from external sources, e.g. Qwest, Verio, US West.

2.      NETWORK DEVELOPMENT - puts in place the needed infrastructure upon which
        ATG will build its products and services. In the Value Chain model
        Network Development provides the basic physical network infrastructure
        from design and build through integration testing.

3.      SERVICE ASSURANCE - is the production engine that operates and maintains
        the network upon which services are built and provided to the company's
        subscribers.

4.      MARKETING - anticipates demand to determine the requirements and
        characteristic of products needed to serve the company's customers now
        and more importantly in the future. The product and service requirements
        developed by the marketing function drive the network infrastructure
        needed to meet these requirements.

5.      SALES - is responsible for bringing the products and services defined by
        Marketing to the end customer.

6.      CUSTOMER SERVICE - is the function that interfaces with the subscribers
        and users of telecommunications service and ensures that the products
        and services are sold, perform correctly and meet the needs of the
        customer.

SUPPORT FUNCTIONS are activities performed by the organization in support of the
primary functions. Support functions are not less important than primary
functions. In fact, they may be crucial to the successful operation of the
primary and support activities.

 If an organization is especially skillful at one or more of these activities,
it can give the primary activities a competitive advantage over competitors who
are less skilled. Such a company is considered to have a "core competency" that
its competitors do not have.

For example, an organization that is extremely good at attracting and retaining
key employees has an advantage over its competitors in marketplaces where key
skilled individuals are scarce. This



         Advanced TelCom Group, Inc. - Confidential and Proprietary       Page 5
<PAGE>   211

"core competency" for attracting and
retaining skilled employees allow the company's primary functions to operate
more effectively than those of its competitors do.

The key support functions for ATG are:

1.      MARKET DEVELOPMENT - the identification and development of new markets
        in which to do business.

2.      OUTSOURCING - the procurement of relationships to perform portions of
        business operations.

3.      HUMAN RESOURCES - deals with hiring, training, developing and separation
        of employees.

4.      SYSTEMS DEVELOPMENT - deals with establishing and maintaining the
        computer hardware and software that are needed by all functions within
        the ATG value chain. This includes acquisition and development of
        application programs and operational systems needed to support both the
        primary and support functions of ATG.

5.      FINANCIAL AND CORPORATE MANAGEMENT - deals with the basic financial and
        accounting functions needed by the firm. Also includes other Corporate
        functions such as securing funding and regulatory affairs.

3 BUSINESS FACTOR ANALYSIS

The business factors analyzed in this section are Goals and Objectives, Critical
Success Factors and Problems. Goals and Critical Success Factors indicate what a
company needs to achieve to be successful. In section 5, these business factors
will be related to ATG's Strategies. Strategies indicate what the company will
do to ensure that goals are achieved, Critical Success Factors are met and
problems are overcome. The following model illustrates the relationship between
these factors:

3.1.1 GOALS

The following items describe the major ATG goals that were identified during the
data gathering process. These goals are supported by quantifiable Objectives,
which are described below:

BECOME THE NUMBER ONE CLEC IN TIER 3 AND TIER 4 MARKETS

ATG is targeting Tier 3 (100,000 - 249,000 population) and Tier 4 (20,000 -
99,999) markets. These markets are typically not targeted by current CLECs. ATG
will concentrate on serving these markets and wishes to become the largest CLEC
serving these markets.

BECOME THE NUMBER ONE CLEC IN EACH MARKET ENTERED

ATG will usually enter a market only if there is no competition from other
CLECs. ATG wishes to become so successful in these markets that it discourages
other CLECs from attempting to enter a city in which ATG is doing business.

QUICKLY EXPAND THE NUMBER OF MARKETS SERVED

ATG is entering three markets initially (Santa Rosa, CA, Tacoma, WA & Salem,
OR). It wants to expand the number of markets rapidly over the next five years.

PROVIDE A UNIQUE COMBINATION OF SERVICE OFFERINGS

ATG will provide a unique combination of services that cannot be obtained from
any other single vendor. These are local phone service, long distance, voice
mail and high-speed internet access.

PROVIDE TOP QUALITY PACKET-SWITCHED  SERVICES

ATG will offer leading edge packet-switched services to its customers including
ADSL, SDSL and derived voice in addition to more standard services such as
dial-up access and web hosting.

PROVIDE EXCELLENT CUSTOMER SERVICE

ATG will provide excellent customer service by having well-trained sales and
customer service staff who are knowledgeable about both ATG's product offerings
and the local community. The customer service staff will also need convenient
access to all of the systems and data they need to do their job.

PRODUCE AN ACCURATE CONVERGENT BILL (ONE BILL, MANY SERVICES

ATG wishes to produce a single bill per customer that will contain information
about all the services provided to the customer.

FOLLOW THE BUSINESS PLAN

Although most of the goals detailed above refer to elements of the Business Plan
"Follow the Business Plan" appears to be a universal sentiment. This includes
not only the things listed above but also making sure that investments are in
line with revenue (i.e. don't spend $20m on systems when there is only $1m in
revenue), verifying that the business plan assumptions are accurate as actual
data becomes available and meeting revenue, new market and subscriber goals.

                                                             ->   Present all ATG services on a single bill
                                                             ->   Provide internet access to billing information

8. Follow the business plan                                  ->   Be in 50 markets by 2005

3.2 FUNCTIONS

Functions are different from organizational units, such as Departments or
Divisions. Functions are what a company does, while organizations are how the
company organizes itself to perform the functions. An organization chart
reflects the organizational structure of the company.

<PAGE>   215

Functions are reflected in the numerous processes that are performed and linked
within the company to bring products and services to the marketplace.
"Marketing" is an example of a function.

ATG Functions are described in Section 2, Value Chain Analysis.

3.3 CRITICAL SUCCESS FACTORS (CSFS)

Critical Success Factors are key factors that the organization must achieve to
ensure success in meeting its goals or objectives. An example of a CSF might be
the completion of a management training program for all first level managers.

GET THE NETWORK FACILITIES UP AND RUNNING ON SCHEDULE

In order to meet the revenue and penetration goals for 1999 the network
facilities that are going to allow for the generation of significant revenue
must be in place and working in accordance with the schedule.

IMPLEMENT EFFICIENT AND ACCURATE OPERATIONAL SUPPORT SYSTEMS (OSS)

In order to provide a high-level of customer service, fast and accurate
provisioning and billing, the appropriate OSS must be in place to support the
business. Especially important are Inventory Management, Order Management and
Billing.

MAKE THE FIRST THREE MARKETS A SHOWCASE FOR THE COMPANY

ATG's performance in the first three markets is necessary for its future
success. If these are not a success then it will not be possible to raise
additional investment to expand the business.

DIFFERENTIATE ATG FROM THE ILEC AND OTHER CLECS IN MARKETS

In the eyes of the customer ATG must differentiate itself from other carriers by
means other than price. This will be achieved by having a focus on building
relationships within the community and providing the highest quality customer
service.

NEED ACCESS TO THE RIGHT CAPITAL

In order to meet the company's expansion plans, including acquisitions, ATG must
be able to get capital at a reasonable cost at the right time.

DEVELOP APPROPRIATE PARTNERSHIPS

ATG does not wish to develop a huge staff or operations infrastructure so it is
relying on partners such as Lucent, Qwest, Verio and AMS to provide products and
services.

INTEGRATION OF ACQUISITIONS

ATG is planning to expand by acquiring existing companies as well as building
its own network. It is essential that the customers served by the acquired
companies be integrated as seamlessly as possible into the ATG environment



         Advanced TelCom Group, Inc. - Confidential and Proprietary      Page 10
<PAGE>   216

INTEGRATION OF THE PACKET-SWITCHING AND VOICE LINES OF BUSINESS

Traditionally, telephone companies and internet services companies have been run
in quite different manners. This is due to a number of factors including the
degree of regulation and the costs associated with developing a network and
providing service. In order to be successful, ATG needs to bring these two
cultures together to produce a seamless service offering to the end customer.

SPEED TO MARKET

ATG follows a very rigorous qualification process to determine if a market
should be developed. This includes the absence of CLEC competition. Once a
market has been selected it is critical that service be offered there as soon as
possible before another CLEC decides to target that market.

3.4 PROBLEMS

A problem is defined as a set of factors that hinder the ability of an
organization to achieve its objectives and critical success factors. An example
of a problem is poorly trained employees. The major problems identified at ATG
are listed below.

LACK OF QUALIFIED STAFF

With the growth of the CLEC and wireless telephony markets, it is becoming
increasingly difficult to find qualified telecom personnel at reasonable
salaries, especially outside of major metropolitan areas. Consequently, it will
be difficult to find the quality and quantity of people needed to run the
business in line with the aggressive expansion goals. A qualified staff is
needed if ATG is going to compete on the basis of quality. Additionally, a
current overall lack of staff is resulting in people being overworked and
possibly "spread too thinly" to do all the work that needs to be done
comprehensively.

COST AND PRICING OF SERVICES

The high cost of unbundled local loops, especially in California, makes it very
difficult to make money. Additionally, the ILECs have been pricing xDSL services
very aggressively, which makes it difficult to compete on price in this arena.

ILEC ROADBLOCKS

The ILECs obviously do not have any incentive to cooperate with ATG. Issues
concerning the availability of co-location space will most likely continue to be
an issue. It is unrealistic to expect that they will perform any better than the
worst case scenario dictated in interconnection agreements. This puts additional
emphasis on ATG to excel so that the ILEC has all the information they need
correctly the first time, so they will have no excuse for performing up to the
level of their agreements. Additionally, some ILECs have resisted swift and
robust implementation of interconnect agreements and new FCC requirements. There
have also been problems with the quality of their outside plant.



         Advanced TelCom Group, Inc. - Confidential and Proprietary      Page 11
<PAGE>   217

NO TRACK RECORD

ATG has no track record of offering services in any market. This makes it hard
to persuade customers, especially business customers, to put their business in
the hands of an unproven company. Since ATG is not employing a low-price
strategy, which might entice some customers, this may make breaking into the
markets even more difficult.

LACK OF OPERATIONS SUPPORT SYSTEMS (OSS) AND BUSINESS SUPPORT SYSTEMS (BSS)

ATG needs to build a portfolio of OSSs and BSSs to support both current
operations and future growth. Some systems are available but many others such as
an integrated order management system and a system to compare ILEC unbundled
loop charges to ATG customers will have to be developed.

INTEGRATION OF ACQUISITIONS BEFORE OPERATIONS ARE STABLE

ATG's expansion plans call for the acquisition of other CLECs and ISPs to
facilitate rapid growth. If these acquisitions are made before ATG has a stable
set of business processes and information systems the changes of a smooth
integration are severely jeopardized.

4 COMPETITIVE ENVIRONMENT ANALYSIS

The BOA Team collected information dealing with the competitive environment in
which ATG operates and the problems and opportunities posed by that environment.
The team analyzed the ability of ATG to compete in the telecommunications
environment.

As an aid to analyzing this information, the BOA team developed the following
models:

1.      Strengths, Weaknesses, Opportunities, Threats ("SWOT") Analysis
2.      Competitive Forces Analysis

4.1 STRENGTHS, WEAKNESSES, OPPORTUNITIES, THREATS

From the information collected as part of the Business Objective Analysis, the
BOA team completed a SWOT analysis model again based on the Porter constructs.
SWOT stands for Strengths, Weaknesses, Opportunities and Threats. The diagram
depicts the SWOT analysis that the BOA team performed on the information gained
from interviews and documents supplied by ATG.

The BOA Team developed a high-level model of the SWOT for ATG. This model
provides the Team with an overall picture of ATG's planned business environment.
This analysis is only a starting point and is not an in-depth analysis. It will
help the ATG Executive Team capitalize on Strengths and Opportunities and
position itself to overcome Weaknesses and Threats. The following diagram
depicts the results of the SWOT analysis.

<PAGE>   219

STRENGTHS - These are the strengths of the organization, which allow it to
effectively compete in the marketplace. Strength should be built upon,
especially if the competitors are weak in the area that the company is strong.
The key strengths of ATG are:

        1.      Start-up Funding: The company has acquired the funding it needs
                to begin business and is well on the way to securing additional
                funding.

        2.      Experienced Executive Team: The executive team and many of the
                employees have been with a start-up company before and
                understand what it takes to make this kind of business
                successful.

        3.      Unique Service Offering (Internet, Local and Long Distance
                Packages): - The combination of these services is currently not
                available from any single provider.

WEAKNESSES - The weaknesses of the organization can put it at a disadvantage,
especially if competitors are strong in the areas in which the company is weak.
Many of these weaknesses offset the strengths that ATG has and limit its
capabilities to capitalize on the opportunities presented to the Company. The
key weaknesses of ATG are:

        1.      ILEC Cooperation - The ILECs have little or no incentive to
                provide exceptional service to ATG. Since ATG will be reliant on
                the ILECs to provide service to their end-customers, this could
                become a serious problem.

        2.      Brand New Organization - It is always a challenge to build an
                organization from ground zero. Many new personnel have to be
                hired and integrated into the business quickly.

        3.      New Operations Systems and Processes - An entirely new set of
                operations systems and operational processes can be both a
                strength and a weakness. However, the goal of excellent customer
                service could initially be compromised if the implementation of
                new systems and processes does not go well.

OPPORTUNITIES - These are environmental and internal factors which present
opportunities for the firm to capitalize on and allow it to gain a competitive
advantage. The key opportunities for ATG are:

        1.      Develop Partnerships - ATG is entering into agreements with
                Lucent and AMS to outsource segments of their operations.
                Drawing on the experience of these companies provides an
                opportunity to benefit from their experience with other
                companies in the field.

        2.      Convergent billing - If ATG can produce a single bill for all of
                the services they provide in a timely fashion this will provide
                a significant competitive advantage.

        3.      State-of-the-art Technology - ATG is starting its internet
                business at the same time as xDSL technology is starting to
                mature. ATG has the opportunity to offer products and services
                in this arena that were not previously available.

        4.      Automation - Since ATG has no legacy systems or processes, it
                can take a "green-field" approach to developing them. This
                allows for the opportunity to automate as much of the operations
                as possible, reducing costs and headcount. An example of this is
                "flow-through" provisioning.

        5.      Industry Consolidation - The CLEC industry has spawned many new
                entrants over the past few years and more companies enter the
                fray every day. In these situations there tends to be a process
                of consolidation with a large number of companies eventually
                combining into a smaller number. This provides the opportunity
                for ATG to purchase other CLECs to rapidly increase its size or
                for ATG to be acquired and maximize investor return.



         Advanced TelCom Group, Inc. - Confidential and Proprietary      Page 14
<PAGE>   220

THREATS - These are environmental and internal factors that can present threats
to the competitive ability or profitability of the company. The key threats
faced by ATG are:

        1.      Rapidly changing technology - ATG is investing a lot of money to
                build a brand new network. Although ATG is using the most
                up-to-date technology available, the marketplace is changing so
                rapidly now that it is hard to judge how quickly the network may
                be outdated.

        2.      Broad range of competitors - Although no one company can provide
                all of the services that ATG can, there are many companies that
                can provide some of these services. However, new CLECs with
                these capabilities are entering the market all the time.

        3.      Funding uncertainty - Although ATG has proved to have extremely
                good contacts in the investment community, the current economic
                situation is subject to rapid change. This could easily effect
                both the availability and cost of funds for future investment.

4.2 COMPETITIVE FORCES ANALYSIS

This analysis looks at five of the forces that may affect ATG as it competes for
market share in the telecommunications marketplace. This analysis is only a
starting point to help identify processes and areas where ATG may place
additional emphasis, to strengthen its position in the markets that it has
chosen. The forces considered include Customers, Suppliers, Competitors and
Regulators. The following diagram summarizes the competitive forces model.

FIGURE 6. COMPETITIVE FORCES MODEL




                        [COMPETITIVE FORCES MODEL CHART]




         Advanced TelCom Group, Inc. - Confidential and Proprietary      Page 15
<PAGE>   221

CUSTOMERS

Companies may have marketing segments in which the customer has strong
bargaining power. This is true if the customer has multiple companies from which
to obtain the needed products and services. Buyer power influences the prices
that firms can charge.

Potential customers for ATG's services will certainly have a choice of
providers. The ILEC, various IXCs and ISPs will all be vying for a piece of the
pie even if there are no other CLECs. This gives the customer a strong
bargaining position. It is crucial to ATG's success that they are able to
effectively differentiate themselves to the consumer from their competitors.

SUPPLIERS

This area of the model deals with the bargaining power of a company's suppliers
and is a key factor that dictates how a company can function in the marketplace.
This is especially true if the suppliers have great bargaining power and can
dictate prices or quantities supplied. Environments where only one or two
suppliers are the source of needed resources can be extremely constraining on
the competitive strategy of a company. Such suppliers can demand high prices for
their products or limit supply. For example, ATG is particularly reliant on the
ILECs as suppliers of the local loop and also co-location space.

Environments where there are many suppliers who compete heavily among themselves
are least restrictive. Forming strong alliances with key suppliers is an
effective strategy many U.S. companies are implementing to ensure a source of
supply at reasonable prices and with the quality needed. If ATG meets its growth
projections it will have significant bargaining power with other categories of
suppliers such as equipment manufacturers (e.g. Lucent, Diamond Lane) and Long
Distance carriers (e.g. Qwest).

COMPETITORS

These are the other companies that offer the same or similar products. The
effectiveness of these competitors and the strategies they employ (e.g., low
cost, product and service differentiation, targeting niches of customers)
dictate how the company must react to overcome the threats posed by these
competitors. The key competitors faced by ATG are:

~       Incumbent Local Exchange Carriers (ILECs)
~       Other CLECs - As of 1/5/99 there are 90 facilities-based CLECs doing
        business in California, and 87 resellers. In Washington state there were
        52 facilities-based CLECs (12/23/98).
~       Inter Exchange Carriers (IXCs)
        ->      Sprint
        ->      AT&T
        ->      MCI-Worldcom
~       Wireless Companies
~       Internet Service Providers (ISPs) for xDSL services e.g. CNM Network,
        Pages3, DSLnetworks, ILECs.

Although none of these competitors can singly offer the same services and
billing arrangements as ATG, they can between them provide significant price
competition.

<PAGE>   223

REGULATORS

In many industries, regulatory agencies greatly influence the environment in
which competitors operate. The telecommunications industry in the U.S. is a
prime example of such an environment. Telecommunications companies who can
interact effectively with the regulatory bodies often position themselves
competitively in the industry. Regulatory decisions often affect the directions
of the entire industry.

There are many unresolved issues as a result of the 1996 Telecom Act and the
picture has been clouded further by Supreme Court ruling on the regulatory
control of the Telecom Act and the pricing of unbundled network elements (UNEs).
ATG is especially sensitive to these issues, as it will be relying on the ILEC
for the local loop, at least in the short to medium term. Changes in pricing and
access could have a significant effect on ATG's business plan.

SUBSTITUTE PRODUCTS

It is important to analyze the development of substitute products as they can
change the whole nature of competition in an industry. Wireless technology can
be viewed as a substitute product that could radically change the environment in
which ATG operates. The advent of cheaper and more effective cellular and fixed
wireless technology could challenge the current network infrastructure that ATG
has put in place. Customers of the future may not be burdened with having to
have wires to communicate. More importantly, future customers of wireless may
not need to obtain service from a telephone company that is geographically
located close to the customer. Customers with such a capability will have a
great deal of bargaining power in obtaining their telecommunication services.

Internet telephony is another possible substitute for traditional telephone
service. This service is growing rapidly in popularity and currently operates in
an unregulated environment.

Cable Modems can provide the same high-speed internet access as the xDSL
technology being employed by ATG. AT&T's acquisition of TCI and alliances with
other cable companies such as Time Warner will probably speed the availability
of telephony services through cable plant. However, the small business segment
of the market that ATG is targeting is not currently well served by the cable
industry.

5 STRATEGY ANALYSIS

Strategies set by an organization indicate the broad directions that must be
undertaken in order to:

- ->      Achieve the organizational goals
- ->      Ensure that critical success factors are met
- ->      Capitalize on opportunities presented to the company
- ->      Leverage the company's strengths
- ->      Overcome problems and company weaknesses
- ->      Meet threats facing the company

Goals, Critical Success Factors and opportunities are indicators of what it is
important for a company to achieve. Strategies indicate how the company will go
about achieving what it considers important.

5.1 KEY STRATEGIC DIRECTIONS

The first thing a company must do is to determine whether it will complete
broadly in its marketplace or to concentrate or segments of its marketplace
(Niching). Once that decision is made then the company must decide if it will
compete by being the low cost producer of services or by differentiating its
product or service to the marketplace it competes in.

A differentiation strategy concentrates on valuing or differentiating the
product or service in the eyes of the buyer. If done successfully the service is
so prized that the buyer is willing to pay a premium for the product.

ATG has chosen a niche strategy by concentrating on providing service to small
business / high-end residential market segment within specific geographical
markets where there is minimal CLEC competition. To execute this strategy
requires that ATG choose suitable markets and provide an attractive combination
of services that the customer cannot receive elsewhere. Key supporting
strategies to accomplish this are:

        1.      CONCENTRATE ON TIER 3 AND TIER 4 MARKETS

                ~       Tier 3: 154 cities with a population of (epsilon)100,000
                        < 249,000
                ~       Tier 4: 1152 cities with a population of (epsilon)29,000
                        < 100,000
                ~       (epsilon) 50,000 business lines
                ~       (epsilon) 100,000 residence lines

        2.      PERFORM IN-DEPTH MARKETING ANALYSIS TO QUALIFY MARKETS

                ~       Minimal CLEC presence
                ~       Cooperative local government
                ~       Favorable regulatory climate
                ~       Favorable ILEC tariff structure

        3.      PROVIDE A UNIQUE MIX OF TELECOMMUNICATIONS PRODUCTS TO CUSTOMERS



         Advanced TelCom Group, Inc. - Confidential and Proprietary      Page 19
<PAGE>   225

                ~       Local
                ~       Voice mail
                ~       Internet Services
                ~       Long Distance
                ~       Convergent bill

ATG is also pursuing a strategy of differentiation from its competitors based on
a local presence and excellent customer service. Key supporting strategies to
accomplish this are:

        1.      PUT THE "LOCAL" BACK IN LOCAL SERVICE

                ~       Having a downtown ATG office where customers can pay
                        their bill or talk to an ATG representative.
                ~       Having sales representatives personally visit all
                        customers with 4 or more lines
                ~       Hiring people with knowledge of the geographic area in
                        which they are working.

        2.      PROVIDE EXCELLENT CUSTOMER SERVICE

                ~       Hiring knowledgeable people.
                ~       Resolving as many issues as possible with only one call
                        to ATG.
                ~       Always having the phone answered by a human being (not
                        voice mail).

        3.      PROVIDE LEADING-EDGE PACKET-SWITCHED PRODUCTS

                ~       Currently ADSL and SDSL.
                ~       Become an early adopter of new technologies.

Additional key strategies that are required of ATG to achieve the desired goals,
meet Critical Success Factors and overcome the identified problems are
summarized as follows:

        1.      STRATEGIC OUTSOURCING OF OPERATIONS WHERE IT MAKES ECONOMIC AND
                BUSINESS SENSE

                ~       Outsourcing network operations to providers of
                        networking services such as Lucent who can provide more
                        sophisticated network provisioning and maintenance at
                        low cost due to economies of scale they have by
                        providing services to a broad range of telephone
                        companies. This will also allow ATG to minimize the size
                        of its internal organization.

                ~       Outsourcing billing and billing mediation operations to
                        AMS.


5.2 SIGNIFICANT RELATIONSHIPS

The following key relationships between strategies, goals, and functions have
been identified:

1.      Strategies key to attaining goals set by ATG
2.      Strategies key to ensuring critical success factors are met
3.      Strategies key to overcoming problem areas
4.      Functions most important to the successful execution of the strategies.

These relationships are described in detail below.

5.2.1 CORPORATE STRATEGIES IMPORTANT FOR ACHIEVEMENT OF STRATEGIC GOALS

There is a key relationship between corporate strategies and ATG's goals. The
strategies are essential to achieving the goals. Furthermore, the goals have an
impact on how the strategies themselves are devised and executed.

In the following matrix, strategies are listed horizontally and goals are listed
vertically. If the BOA team found that a goal is supported by a strategy, they
checked the appropriate row and column. The more checks in a row, the more
important a strategy is to meeting the goals of the organization.

5.2.2 CORPORATE STRATEGIES IMPORTANT FOR ACHIEVING CRITICAL SUCCESS FACTORS
      (CSFS)

Corporate strategies have been derived from the interviews conducted with
various ATG executives. The relationship between corporate strategies and
critical success factors is important because specific strategies will be
instrumental in ensuring the Critical Success Factors are met. The relationships
have been established from interviews and various documents provided by ATG and
are documented in the following matrix

In this matrix, strategies are listed horizontally and Critical Success Factors
are listed vertically. If the BOA team found that a strategy helps fulfill a
CSF, they checked the appropriate row and column. The more checks in a column,
the more important is a strategy to ensuring that Critical Success Factors are
met.

The matrix identifies that most strategies will play a key role in meeting the
following Critical Success Factors:

1.       Make the first three markets a showplace for the company
2.       Differentiate ATG from the ILEC and other CLECs in the market

5.2.4 FUNCTIONS SUPPORTING STRATEGY EXECUTION

Strategies are what the company does to achieve its goals, ensure the Critical
Success Factors are met and address the major problems facing it. Functions are
groupings of major activities performed within the organizational structure of
the company. Organizations performing functions are how a company goes about
executing its strategies.

Mapping corporate strategies to functions performed by the enterprise highlights
those functions that are key to successful execution of the corporate
strategies. The matrix below indicates which of the ATG value chain functions
play a role in carrying out the major strategies of the company.

The columns of this matrix list the ATG functions while the strategies are
listed in the rows of the matrix. If the BOA team found that a function supports
a strategy, they checked the appropriate row and column. The more checks in a
column, the more important a function is to the execution of the ATG strategic
directions.

To properly assess the importance of a function, we need to understand how
important a strategy is to achieving goals, meeting Critical Success Factors and
overcoming problems. The following table indicates how many goals, Critical
Success Factors and problems are addressed by each strategy. This table was
derived from the matrices developed earlier in this chapter. The numeric weight
column represents an overall importance of a strategy derived by adding the
number of goals, Critical Success Factors and problems addressed by that
strategy.

APPENDIX A: HOW THE BUSINESS OBJECTIVE ANALYSIS REPORT WAS PRODUCED

The process of preparing this document was divided into four stages:

        ->      Gather data
        ->      Analyze the information
        ->      Summarize and consolidate the information
        ->      Develop this Business Objective Analysis to present the team's
                conclusions.

INFORMATION GATHERING BY INTERVIEWS

To gather key business information, the project team arranged interviews with
executives throughout ATG. Before the start of the interviews, questionnaires
were developed. The questions that were asked during the executive interviews
are listed in Appendix A.

The project team then met with the executives who were to be interviewed to
discuss and explain each question and document their answers. A total of 20
interviews were conducted with senior and operational executives. After each
interview, the interview team met to consolidate their notes into a single view
of the questionnaire.

INFORMATION GATHERING BY DOCUMENT REVIEW

Along with the interviews, there were key documents that were a valuable source
of information for the Business Operations Analysis. Please see Appendix A for a
list. The project team reviewed each of these documents to identify executive
strategies and key business perspectives. Similar to the interview
questionnaires, these documents were used as a reference for the documentation
and analysis of key relationships.

INFORMATION ANALYSIS BY TELECOMMUNICATIONS SUBJECT MATTER EXPERTS

The BOA team includes telecommunications subject matter experts. They have broad
experience in telephone company operations and are able to provide insights into
methods, information needs and customer service operations. They were able to
build models of processes that make up a modern phone company and apply their
knowledge of current trends to the development of this document.

INFORMATION ANALYSIS, CONSOLIDATION AND DOCUMENTATION OF CONCLUSIONS

Information from interviews, documents and subject matter experts was collated.
It was then used to create ATG Strategy Models, which are representations of
business factors such as ATG goals, objectives, critical success factors etc.
These Strategy Models are known as "objects'.

1       EXECUTIVE SUMMARY

1.1 OBJECTIVE OF THE OPERATIONAL READINESS PLAN

Advanced TelCom Group, Inc. (ATG) has contracted with Lucent Technologies
Professional Services to provide a full range of Network Reliability Center
(NRC) services along with American Management Systems (AMS) providing billing
and other revenue assurance outsourcing services and Digital Counterpart Inc.
(DCI) providing an order entry and order tracking solution. These services
include a team of professionals to work with ATG management to develop an
Operational Readiness Plan. The Operational Readiness Plan collects valuable
information, performs analysis and serves as a useful document to assist ATG
management with the successful implementation of their entry into offering
integrated communications services. Initially, these service offerings will be
provided by ATG in three markets. At start-up in April of this year, ATG will
resell Incumbent Local Exchange Carrier (ILEC) and Internet Dial-up services to
its customers. As resale and Dial-up services are being delivered to business
customers, ATG will be building their own network and will be in the final
stages of offering the following Facilities-based services:

        -       Local phone service
        -       Long distance phone service
        -       Voice mail
        -       Internet services (Dial-up, xDSL, Web Hosting, Web Content,
                etc.)


The four phases that the Operational Readiness Plan encompasses are:

        -       Business Objective Analysis (BOA)
        -       Present Method of Operations (PMO): describes the ILEC resale
                and Internet dial-up phase of the ATG business
        -       Interim Method of Operations (IMO): describes the continued
                resale and initial facilities-based phase of the ATG business
        -       Future Method of Operations (FMO): describes the predominantly
                facilities-based phase of the ATG business. This phase will be
                covered as part of Project Cabernet which will produce a fully
                automated Order Management solution.

This document describes the PMO phase of the Operational Readiness Planning
project.

<PAGE>   243



                                  [FLOW CHART]



1.      A BUSINESS OBJECTIVE ANALYSIS (BOA). Completion of the BOA on April 15,
        1999 was the first step in the Operational Readiness Plan. The BOA
        provides an analysis of corporate objectives and strategic directions as
        they have been understood by ATG's management team. The BOA is part of
        the Operational Readiness Plan and as such is not an independent
        document that defines strategies, planning or specific actions.

2.      A PRESENT METHOD OF OPERATION (PMO). As the second step in the
        Operational Readiness Plan, Lucent will develop process models that
        describe the way ATG will be doing business in the Resale and Internet
        Dial-up phase of their business.

3.      AN INTERIM METHOD OF OPERATIONS (IMO). As a third component of the
        Operational Readiness Plan, Lucent will deliver to ATG a document which:
        (1) will analyze the gaps between the Present Method of Operations and
        where ATG wishes to be after the implementation of the Lucent network;
        (2) documents ATG's business processes in the Facilities-based
        environment; and (3) may make recommendations to improve the efficiency
        and effectiveness of ATG's business operations.

        There may be additional iterations of the IMO as a result of
        opportunities for continuous process improvement during the early stages
        of the Facilities-based environment.

4.      A FUTURE METHOD OF OPERATIONS (FMO). In this phase, the Plan will be
        updated to reflect the changes that are introduced as a result of the
        mechanization of the Order Management function (Project Cabernet).

1.2 OBJECTIVE OF THE PRESENT METHOD OF OPERATIONS (PMO) PHASE
The intent of this phase is to understand and document ATG's business plans and
strategies for entering the telecommunications market by reselling ILEC voice
services and offering ATG Internet dial-up data services to its customers. This
information will be used in constructing the future state processes in the FMO
phase. The specific Process Flows include Prospecting, Pre-Order, Order
Management, Customer Service, Customer Care/Trouble Management, and Billing.
This valuable information will be used for gap analysis that must be addressed
in the FMO.

1.3   SCOPE
The PMO initiative and this document only pertains to those start-up services
offered for resale and Internet dial-up by ATG in the markets it is entering.
ATG plans to resell certain ILEC services and offer ATG branded Internet dial-up
data services in the three market areas identified for start-up, while the
Lucent switches are being installed and processes and procedures are developed
to begin offering integrated voice and data services in a Facilities-based
environment. The ILEC services that ATG plans to offer for resale during this
start-up phase include POTS lines, business trunks, Centrex services, ISDN
services, Voice Mail services, and Internet (standard dial-up and ISDN
connectivity). During facilities-based operations, ATG be required to continue
to offer voice services via ILEC Unbundled Network Elements (UNEs) often
referred to as Unbundled Loops.

1.4   APPROACH
The PMO was developed using the following approach:

1. IDENTIFY THE START-UP SERVICES AND PRODUCTS TO BE OFFERED

After several key meetings and working sessions with the appropriate ATG
managers it was determined that ATG's start-up offering would be as a reseller
of ILEC and ATG branded Internet Dial-up services to its customers.

2. EXAMINE EXISTING DOCUMENTS, PROCESSES AND DATA

Draft Requirements, Methods, and Procedures developed by AMS and DCI were
reviewed and updated, and ATG Business Plans and Market Selection processes were
reviewed to develop process work flows and analyze the present method of
operation. This analysis provides an assessment of how well the goals and
objectives of ATG, as identified in the BOA are likely to be met.

3.  MEET WITH KEY ATG MANAGERS

The Lucent Team conducted or participated in strategy sessions and meetings with
ATG managers and Subject Matter Experts (SMEs) to discuss plans for customer
service, processing information for Local, Internet and Long Distance services
and merging these procedures for operations usability. Most of the process data
was extracted from information provided by other partners who had previously
developed some ATG operations methods and procedures for use during the voice
resale and dial-up data phase.

<PAGE>   245

4.  CONDUCT A STRATEGY SESSION WITH THE NRC

Using information collected from the previous steps, a meeting was held with NRC
Managers, to define the procedures and to discuss anticipated results of the NRC
handling the Trouble Management/Customer Care responsibilities.

5.  DEVELOP PROCESS WORK FLOWS

Flows were developed for each of the major processes.

2    INTRODUCTION

The PMO phase of the Operational Readiness Plan models services and network
operations for the resale to its customers of ILEC services, as is planned for
start-up by ATG in May, 1999. The intent of this phase is to understand and
document ATG's business plans and strategies to perform gap analysis and
evaluate the probable success rate for this market entry. This detail permits:

        -       Review of essential day-to-day service activities to develop key
                performance indicators to be detailed in the FMO.

        -       Identify opportunities for development of additional processes
                and procedures that may be vital to a successful implementation.

        -       Review of the quantity and quality of the staff required, and in
                place, to meet the business needs and the needs of the customer.

        -       Identify the required interactions and information flows between
                ATG corporate, ATG market, NRC services, and AMS services
                affecting end-to-end service delivery.

To proceed with the analysis, the PMO Team used various documents and reference
material supplied by ATG and information collected from interviews with the ATG
executives and subject matter experts. The project team reviewed each of the
following documents to identify executive strategies and key business
perspectives relating to the planned PMO. Similar to the interview
questionnaires, these documents were used as a reference for the documentation
and analysis of key relationships.

4.4 ORGANIZATIONAL RECOMMENDATIONS

ROLES OF CENTRALIZED AND LOCAL ORGANIZATIONS

In the current organization, both the customer service and field support
organizations in each region report up through the general manager. If this
structure is to be maintained then the corporate customer service and field
support organizations must still play a significant role in the management of
these groups (dotted line responsibility). It is recommended that the corporate
organizations play a policy making and quality assurance role with respect to
the local organizations. Specifically:

- -  Establishing policies and procedures
- -  Training
- -  Establishing job descriptions and levels
- -  Determining metrics and measurement criteria
- -  Evaluation of effectiveness of current processes
- -  Establishing escalation scenarios

If ATG is to successfully expand into a large number of markets, there must be a
high degree of standardization. This will make entry into these markets much
smoother. This, of course, must be balanced against the need to make adjustments
for local conditions.

CUSTOMER ADVOCATE / OPERATIONS MANAGER

The day-to-day operations of ATG are spread out over a number of organizations
and executive responsibilities. It is important to have a single individual
responsible for operations as opposed to policy-making and business development.
This person's primary responsibility would be to ensure customer satisfaction
from the initial sales visit through establishment of service and including
ongoing contact such as receiving bills, trouble calls and customer service
activity.

VENDOR MANAGEMENT

Since ATG has chosen to outsource major portions of their operations, Vendor
Management becomes even more important than usual. A manager should be appointed
to manage the ongoing relationship with major vendors, especially Lucent, AMS
and DCI.

ATG PROJECT MANAGERS

ATG has outsourced the project management role to its vendors for both the
Resale and Facilities phases of the project. These endeavors are so important to
ATG that the person in charge should be a key ATG executive. Progress in these
areas may have suffered because close ATG oversight was not available.

LACK OF RESOURCES

It is part of ATG's business philosophy not to build a vast internal
organization, hence the outsourcing of large portions of the business to Lucent
and ATG. Also, since there is no revenue currently flowing into the company it
is understandable that ATG would want to keep costs down. However, in almost all
areas of the organization there appears to be insufficient staff to



Page 22     Advanced TelCom Group, Inc. - Confidential and Proprietary
<PAGE>   262

perform the work at hand, or to handle the potential level of business that is
anticipated. This has been a contributing factor to missing deadlines and
delaying the start of business.

If the Internet business is successful, the Internet Network Operations Center
(INOC) will be severely understaffed. If either the Internet or Resale
businesses are successful, then the local branches will find themselves severely
pressed to meet customer commitments. If the business is successful additional
resources will need to be hired anyway. Hiring sooner rather than later will
enhance ATG's chances of providing excellent customer service. Given the
difficulty of hiring qualified staff, it is better to be out in front of this
issue.

Building a telephone and an Internet company from scratch is a complex
operation. It will be difficult to achieve successfully without the right type
and number of resources.

shall provide training to ATGI's personnel. The Parties shall subsequently
negotiate the dates and times of such training, and unless otherwise agreed,
training shall take place in Boulder, Colorado at SCC's offices. If SCC
ultimately agrees to provide training at any other location, SCC shall be
reimbursed for its costs of travel, which costs shall not exceed the allowances
for same as set forth in ATGI's then-current, standard travel policy. Once
scheduled, training classes may be canceled by ATGI without penalty upon ten

SCC's time and its cost of travel and training materials actually incurred by
SCC in preparation for the course only for those costs not otherwise recoverable
by SCC.

2.6      NEW SERVICES

         At SCC's sole discretion, New Services will be periodically offered to

schedule; (4) the initial non-recurring charges and/or additional recurring
charges associated with the service; and (5) any other information deemed

2.10    ELECTRONIC EXCHANGE

        Except as may otherwise be provided herein, the Parties will use and
implement electronic automation procedures to facilitate communication,
coordination, maintenance, and management of the Services. In addition, if

communications or other crucial aspects which relate to the provision of SCC's
Services or New Services, the party initiating such modification shall provide
to the other party written notice of such modification not less than ninety
(90) days prior to such modification, and the other party shall have not less
than one hundred eighty (180) days to implement the changes necessary to
accommodate such modification. Responsibility for payment of any additional
costs for the non-initiating Party in order to accommodate such change shall be
negotiated by the Parties in good faith.

2.11    UNIFORMITY

        The Services shall not be either province, state, or regionally
specific unless it is legally mandated by the legal governing body.

                            3. ATGI RESPONSIBILITIES

        ATGI'S contractual obligations and responsibilities are those stated in
this Agreement and its Exhibits, as may be amended by mutual written agreement
of the Parties.

                            4. TERM AND TERMINATION

4.1     TERM

        The term of this Agreement shall begin upon the Effective Date as first
stated above and continue for a period of three (3) years thereafter unless
earlier terminated under the terms of this Agreement ("Initial Term"). Following

(1) year terms unless terminated at the end of a renewal term upon no less than
180 days advance written notification by the terminating Party.

4.2     TERMINATION

        Either party may terminate this Agreement in the event that the other
Party is in default under the terms or conditions of this Agreement including,
but not limited to, any amendments thereto or any terms and conditions
contained in the SOW, any other authorized exhibits or

amendments thereto. The non-defaulting Party shall promptly provide written
notice of default to the defaulting Party. Except for a default alleging
non-payment, the defaulting Party shall have thirty (30) days from the
effective date of the written notice to cure such default or to provide a plan
to cure same which plan must be accepted in writing by the non-defaulting
Party. For a default for non-payment, the defaulting Party shall have fifteen
(15) days in which to cure such default. If a timely cure is not made as
provided herein, then this Agreement may be terminated at the option of the
non-defaulting Party.

4.3  ORDERLY TRANSITION

     Upon expiration or proper termination hereof, SCC will cooperate in the
orderly transition of the Services to ATGI or its agent and will make reasonable
efforts to minimize any disruption of ATGI's E9-1-1 service. At such time, and
with respect to the ATGI-relevant data and databases that SCC legally controls
hereunder, SCC will deliver to ATGI such data contained in such databases, and
other information that is necessary to allow ATGI to be substituted for SCC in
this regard; provided, however, that SCC shall not be obligated to do so if such
delivery or other performance would violate the confidentiality provisions of
this Agreement, result in a breach of contract to which SCC is a party as of the
Effective Date hereof, violate any other law or private right, convey to ATGI
any intellectual property or other right to which ATGI is otherwise un-entitled
hereunder, or otherwise unreasonably subject SCC to civil or criminal
prosecution. Such data and information shall include but not be limited to ATGI
Results (as defined herein) along with the data needed to perform said Services,
all in a readable file or files of reasonable structure and convertible with
commercially available software, which data and information shall be current as
of the date of such transition.

      If ATGI requests that SCC continue, beyond the effective date of
expiration or termination, to provide any portion or all of the Services that
SCC would not otherwise be contractually obligated to provide under the terms
and conditions of this Agreement, ATGI shall compensate SCC for such Services
at the same rate as otherwise would be applicable under this Agreement for such
Services for so long as such Services or portions thereof are being provided.


                            5.    PRICE AND PAYMENT

5.1   SERVICES FEES

      The Fee and Payment Schedule, attached hereto, marked as Exhibit B and
incorporated herein, sets forth the charges and fees payable by ATGI to SCC for
the Services.

      5.1.2 ATGI's OPTION FOR "PRICING ADJUSTMENT."

      ATGI will initially pay the rates pertaining to the MBFs as set forth in
Exhibit B based on the number of ATGI's actual Base Records. Unless ATGI
exercises its option described herein, ATGI will, for the duration of this
Agreement, pay such rates based on the number of ATGI's actual Base Records. If
ATGI exercises such option, the MBFs shall be determined in the


- -------------------------------------------------------------------------------
Standard Contract                       9                              05/14/99

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

manner set forth below.

     At ATGI's sole option, ATGI may invoke a "Pricing Adjustment", as described
below, by electing to pay MBFs at the rates set forth in Exhibit B based on the
number of ATGI's projected Base Records instead of the number of ATGI's actual
Base Records. If ATGI exercises such option, then no later than sixty (60) days
prior to the effective date of the Pricing Adjustment, ATGI will provide SCC
with ATGI's forecast of ATGI's projected number of Base Records which ATGI
expects will exist one (1) year following the Pricing Adjustment. Such forecast
shall be in writing and delivered to SCC's Vice President of Sales pursuant to
the Notice requirements of this Agreement. ATGI's Projected Base Records shall
be reasonable and shall be consistent with ATGI's overall business plans, and
SCC shall be given a reasonable opportunity to verify this criteria for
reasonableness and consistency.

     If ATGI exercises its option to invoke the Pricing Adjustment, and, if at
the end of the fifth (5th) month following the Pricing Adjustment, ATGI's actual
Base Records are not equal to or greater than [*] of the number of Projected
Base Records, then: (a) ATGI will thereafter pay the MBFs based on the actual
number of ATGI's actual Base Records, and (b) ATGI will be invoiced
retroactively for the preceding five (5) months in the amount of the difference
between the MBFs based on the Projected Base Records and the MBFs based on the
actual number of Base Records.

     If ATGI exercises its option to invoke the Pricing Adjustment, and, if at
the end of the fifth (5th) month following the Pricing Adjustment, ATGI's actual
Base Records are equal to or greater than [*] of the total number of the
Projected Base Records, ATGI shall continue to pay the MBFs based on the number
of Projected Base Records instead of the number of actual Base Records; provided
that if the number of ATGI's actual Base Records exceed ATGI's Projected Base
Records, ATGI will pay based on the number of actual Base Records. Regardless of
the outcome of the exercise by ATGI of its option, the rate at which ATGI shall
be obligated to pay MBFs, after the first (1st) year following the Pricing
Adjustment and beyond, will be based on actual Base Records.

5.2  AUDITS

     At its sole expense, SCC shall maintain complete and accurate books and
records with respect to the Project and the Services, and said books and
records shall be maintained in accordance with generally accepted accounting
principles. Each Party shall have the right to audit the books and records of
the other that relate specifically to the calculation of the number of
Subscribers and related fees. In addition, ATGI shall have the right to audit
the books and records of SCC that relate to SCC's data-protection and security
obligations hereunder. Such audits may be performed at the premises of the
other Party, shall be limited to once per calendar year (except for good cause
reasonably demonstrated) and shall only be allowed with not less than fifteen
(15) days advance written notice to the audited Party. Each Party will be
responsible for its own costs related to such audits. "Undisputed" invoices, as
defined herein, which are not adjusted within eighteen (18) months of the date
of such invoice shall be deemed accepted by the Parties, regardless of whether
such invoice was included in a prior or subsequent audit.

5.3  SET-OFF

     All legitimate and reasonable claims for money due or to become due from
ATGI shall be subject to deduction or set-off by ATGI by reason of any such
amounts due ATGI pursuant to this Agreement; however no set-off or
"cross-collateralization" shall be permitted hereunder in connection with
amounts that may be in dispute or owed pursuant to any other transaction or
agreement between the Parties.

5.4  DISPUTED INVOICES

     In the event of a disputed invoice, ATGI shall notify SCC within twenty
(20) days of the receipt of any such invoice and identify the nature of the
dispute or inaccuracy. ATGI shall pay any undisputed amounts set forth in said
invoice in accordance with the provisions hereof pertaining to normal payment
of invoices. Both parties shall in good faith investigate and attempt to
resolve the outstanding disputed amount, and once resolved, any payments owed
shall be promptly paid.

5.5  TAXES

     Fees and charges payable hereunder shall not include any sales, use,
excise, transaction or other similar taxes levied against or upon the
furnishing or receipt of Services. Further, the amounts payable by ATGI
hereunder shall not include any federal, state and local taxes, taxes that are
based on SCC's net or gross receipts, franchise taxes or other taxes based on
SCC's corporate existence or status, personal property taxes on licensed
software and taxes that may be due in whole or in part because of any failure
by SCC or its agents to file any return or information required by law, rule or
regulation. If any sales or other taxes related to SCC's provision of Services
are payable or mandated by current or prospective application of law, they
shall be separately stated on the monthly invoice to ATGI, and ATGI shall be
responsible for paying same in accordance with the terms and conditions set
forth in this Section 5 for payment of invoices. ATGI shall reimburse SCC for
any penalties or interest actually levied upon SCC with respect to such taxes
only if ATGI's acts or omissions solely caused such penalty or interest to be
levied.

5.6  OTHER CHARGES

     Charges for miscellaneous services not contemplated herein will be offered
to ATGI on a time-and-materials basis using SCC's then-current rates for same.
In the event ATGI requests that SCC provide such services, SCC shall first
furnish ATGI with an estimate of the amount of such charges (the "Other
Charges"), which, upon written agreement of the Parties, may include travel and
other related expenses, and shall specify a reasonable "not-to-exceed" billable
amount. Billings of Other Charges for the requested services shall not exceed
the specified amount without ATGI's prior written approval. Other Charges shall
be billed in arrears, after provision of the relevant services, and ATGI shall
pay Other Charges within thirty (30) days of ATGI's receipt of invoices related
to such services. SCC shall be responsible for the normal, non-fixed costs and
fees for acquiring MSAGs ("Master Street Address Guides") in an amount not to

services and as necessary for SCC to provide its Services, New Services and
Add-On Services without the disclosure of Confidential Information as required
under this Agreement.


                              8.   CONFIDENTIALITY

8.1  CONFIDENTIAL INFORMATION

     During the course of this Agreement, either Party may receive or have
access to confidential information of the other. "Confidential Information"
means any confidential, private, or proprietary information or data disclosed
by a Party (the "Disclosing Party") to the other Party (the "Recipient") under
or in contemplation of this Agreement which (a) if in tangible form or other
media that can be converted to readable form is clearly marked as Confidential,
proprietary, or private when disclosed, or (b) if oral, or visual, is
identified as Confidential, proprietary, or proprietary on disclosure. The
terms "Disclosing Party" and "Recipient" include each Party's corporate
affiliates that disclose or receive Confidential Information. The rights and
obligations of the Parties shall therefore also inure to such affiliates and
may be directly enforced by or against such affiliates. The Recipient
acknowledges the economic value of the Disclosing Party's Confidential
Information. The Recipient therefore, shall:

     (i)   use the Confidential Information only in connection with the
     Recipient's performance of its obligations or in exercising its rights
     under this Agreement;

     (ii)  restrict disclosure of the Confidential Information to employees of
     the Recipient and its affiliates with a "need to know" and not disclose it
     to any other person or entity without the prior written consent of the
     Disclosing Party;

     (iii) advise those employees who access the Confidential Information of
     their obligations with respect thereto; and

     (iv)  copy the Confidential Information only as necessary for those
     employees who are entitled to receive it and ensure that all
     confidentiality notices are reproduced in full on such copies.

8.2  EMPLOYEES

     For the purposes of this Agreement only, "employee" includes third parties
retained by the Parties for temporary administration, clerical, or programming
support. A "need to know" means that the employee requires the Confidential
Information to perform his or her responsibilities in connection with this
Agreement.

8.3  EXCEPTIONS

     The obligations of this section shall not apply to any Confidential
Information which the Recipient can demonstrate:

- --------------------------------------------------------------------------------
                         SCC PROPRIETARY & CONFIDENTIAL
<PAGE>   17
     (i)   is or becomes available to the public through no breach of this or
     any other agreements;

     (ii)  was previously known by the Recipient without any obligation to hold
     it in confidence;

     (iii) is received from a third party free to disclose such information
     without restriction;

     (iv)  is independently developed by the Recipient without the use of
     Confidential Information of the Disclosing Party;

     (v)   is approved for release by written authorization of the Disclosing
     Party but only to the extent of such authorization and without any
     disassembly, reverse engineering, or similar undertaking by Recipient; or

     (vi)  is required by law or regulation to be disclosed, but only to the
     extent and for the purposes of such required disclosure, and only if the
     Recipient first notifies the Disclosing Party of the order and permits the
     Disclosing Party to seek an appropriate protective order.

8.4  OWNERSHIP OF CONFIDENTIAL INFORMATION

     Confidential Information, including permitted copies, shall be deemed the
property of the Disclosing Party. The Recipient shall, within twenty (20) days
of a written request by the Disclosing Party, return all Confidential
Information (or any designated portion thereof) including all copies thereof,
to the Disclosing Party or if so directed by the Disclosing Party, destroy such
Confidential Information. The Recipient shall also, within ten (10) days of a
written request by the Disclosing Party, certify in writing that it has
satisfied its obligations under this section. If the Recipient fails to abide
by its obligations under this section, the Disclosing Party shall be entitled
to immediate injunctive relief in addition to any other rights and remedies
available to it at law or in equity.

operate its business and to perform the obligations imposed upon it hereunder.

     9.2.2  ATGI has no knowledge of any existing software viruses contained in
the SCC software or other software used in performing the Services that would
materially impact ATGI's performance hereunder. If ATGI becomes aware of any
such viruses in its software used in connection with its performance hereunder,
it will advise SCC in writing immediately. If SCC's performance hereunder is
materially and negatively impacted by ATGI's failure to notify SCC in a
reasonably timely fashion of its knowledge of such viruses, ATGI shall be
responsible for such reasonable and proximate consequences, and SCC shall be
excused from responsibility hereunder with respect to those matters proximately
affected. Upon learning of such a virus in its software, ATGI shall use its best
efforts to remedy it as soon as possible, at no cost to SCC.

9.3  EXCLUSION

     EXCEPT AS EXPRESSLY PROVIDED HEREIN, SCC MAKES NO EXPRESS OR IMPLIED
WARRANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR

                              10. INDEMNIFICATION

10.1     GENERAL INDEMNIFICATION

         SCC shall indemnify and hold harmless ATGI and its corporate
affiliates and the officers, directors, employees, and agents of ATGI and its
corporate affiliates, and the successors and assigns of all of the foregoing,
against and from any and all actual losses, damages, expenses (including,
without limitation, attorneys' fees and costs), claims, suits and liabilities,
whether based in contract or tort (including strict liability), to the extent
that such losses, damages, expenses, demands, claims, suits and liabilities are
legally-imposed, despite the protections that may be available to ATGI and SCC
described in Section 10.3 herein below, and that arise out of or in connection
with: (1) SCC's negligent or intentional acts or omissions, or those of its
employees or agents or subcontractors, (2) the failure of SCC (or its employees
or agents or subcontractors) to fully comply with the terms and conditions of
this Agreement (including but not limited to each SCC representation and each
SCC warranty under this Agreement), or (3) assertions under Worker's
Compensation or similar laws made by persons furnished by SCC. ATGI shall
promptly notify SCC of any written claim, loss or demand for which SCC is
responsible under this Section. If SCC acknowledges in writing the applicability
of the indemnification provisions of this Section 10.1 to a claim or action, SCC
shall have the right to conduct the defense of such claim or action and all
negotiations for settlement or compromise, unless otherwise mutually agreed to
in writing by the Parties hereto. However, ATGI, at its own expense, shall have
the right to participate in the defense of any such suit or proceeding through
counsel of its choosing.

10.2     INTELLECTUAL PROPERTY INDEMNIFICATION

         SCC shall defend, at its sole cost and expense, any claim or action of
any kind against ATGI for alleged violation, infringement or misappropriation of
any patent, copyright, trade secret or other intellectual property right based
on the use of SCC products or services under this Agreement. SCC shall indemnify
and hold harmless ATGI and its officers, directors, employees, and agents and
their successors and assigns against and from any and all actual losses,
liabilities, damages, claims, demands and expenses (including, without
limitation, reasonable attorneys' fees) arising out of or related to any such
claim or action. If SCC acknowledges in writing the applicability of the
indemnification provisions of this Section 10.2 to a claim or action, SCC shall
have the right to conduct the defense of any such claim or action and all
negotiations for settlement or compromise, unless otherwise mutually agreed to
in writing by the Parties hereto. However, ATGI, at its own expense, shall have
the right to participate in the defense of any such suit or proceeding through
counsel of its choosing.

         If any SCC product used to provide the Services under this Agreement
becomes involved in any claim or action described above, or is held to
constitute a violation, infringement or misappropriation of a third party's
intellectual property rights and the use thereof is enjoined, then SCC shall, at
SCC's expense and option:

compatible and functionally equivalent products that lawfully may be used by SCC
for ATGI.

10.3     ATGI IMMUNITY

          To the extent permitted by applicable law, SCC shall be entitled to
not less than the same benefits and protections afforded by any law, regulation,
contract or other applicable rule which extends to ATGI in any form, including
but not limited to governmental or other immunity, indemnification or other
protection which relates to the provision of emergency 9-1-1 services by ATGI
in its capacity as a telecommunications service provider. ATGI acknowledges and
agrees that SCC shall be considered ATGI's authorized agent in this regard.

11.1     CONSEQUENTIAL DAMAGES

         EXCEPT WITH RESPECT TO SCC'S OBLIGATIONS AS SET FORTH IN SECTIONS 10.1

HARDWARE, SOFTWARE OR OTHER PRODUCTS, MATERIALS, OR SERVICES PROVIDED PURSUANT
TO THIS AGREEMENT OR THE PERFORMANCE OR NONPERFORMANCE OF OBLIGATIONS UNDERTAKEN
IN THIS AGREEMENT), TORT, (INCLUDING NEGLIGENCE), STRICT PRODUCT LIABILITY OR

         SCC shall maintain during the term of this Agreement: (1) Workers'
Compensation insurance as prescribed by the law of the state or nation in which
the Work is performed; (2) employer's liability insurance with limits of at
least $500,000 for each occurrence; (3) comprehensive automobile liability
insurance if the use of motor vehicles is required, with limits of at least
$1,000,000 combined single limit for bodily injury and property damage for each
occurrence; (4) Commercial General Liability ("CGL") insurance, including
Blanket Contractual Liability and Broad Form Property Damage, with limits of
at least $1,000,000 combined single limit for bodily injury and property damage
for each occurrence; (5) Professional Liability or Errors and Omissions
insurance in the amount of at least $1,000,000 (one million dollars) for each

$5,000,000 per occurrence and aggregate in excess of the underlying coverage
required above. The CGL, employer liability and automobile liability policies
named above shall designate ATGI and its officers, directors and employees (all
herein referred to in this clause as "ATGI") as an Additional Insured. All such
insurance must be primary and required to respond and pay prior to any other
available coverage.

12.2 EVIDENCE OF COVERAGE

         Upon ATGI's request, SCC shall furnish certificates evidencing the
foregoing insurance. ATGI shall be notified in writing at least thirty (30) days
prior to any cancellation of the policy.

                 13. RECURRING SERVICE ERRORS/LIQUIDATED DAMAGES

13.1 RECURRING SERVICE ERROR

         If any aspect of the Services are deficient on a recurring basis, as
such deficiency is defined herein below as a "Recurring Service Error", then
upon written notice from ATGI to SCC, SCC shall promptly perform a root cause
analysis, in accordance with the escalation procedures contained in this
Agreement and in the SOW, to determine the cause of such recurring service
errors. A Recurring Service Error is any material non-compliance with the
Services which has repeatedly occurred on at least three separate occasions
during any consecutive three month period. Within seven (7) days of receiving
notice from ATGI of a Recurring Service Error, or upon SCC's own discovery of
same, SCC shall provide ATGI with a written copy of its analysis, which shall
include an action plan containing a reasonably detailed description of
corrective action to be taken by SCC and the date by which such corrective
action shall be completed. SCC shall correct such Recurring Service Error within

receipt of such notice to the reasonable satisfaction of ATGI in accordance
with its action plan. ATGI may elect to immediately terminate this Agreement
if SCC fails to cure any Recurring Service Error within said thirty (30) day
period.

13.2     LIQUIDATED DAMAGES

         If ATGI elects not to terminate this Agreement as specified herein
above, ATGI may instead elect to compel SCC to pay, or credit, ATGI the
liquidated damages described herein for each Recurring Service Error. Liquidated
damages for each Recurring Service Error shall equal the lesser of: [*] The
Parties acknowledge and agree that all amounts payable to ATGI as "liquidated
damages" under this Article are liquidated damages and not a penalty and are
reasonable and not disproportionate to the presumed damages to ATGI in lost
revenues and other damages that would result from a failure by SCC to comply
strictly with this Agreement. SCC's payment of liquidated damages under this
article shall in no way affect ATGI's right to terminate this Agreement, or any
portion hereof or thereof, or to pursue any other rights except that ATGI's
election of liquidated damages in this regard shall prohibit ATGI from pursuing
any other remedy available to ATGI under this Agreement or applicable law with
respect to recovery of damages related to the particular Recurring Service Error
for which the liquidated damages were paid.

Without limiting the generality of the foregoing, neither Party shall publish,
use or disclose the other Party's names or marks (or any variations thereof)
without the prior written consent of the other Party which consent shall not be
unreasonably withheld. ATGI hereby authorizes SCC to utilize ATGI's name as part
of SCC's list of customers in connection with SCC's standard service proposals
and other marketing materials.

14.2     ASSIGNMENT

         This Agreement shall be binding upon the successors and assigns of both
parties, provided, however, that no assignment, delegation or other transfer
shall be made by either party without the prior written approval of the other,

management for each Party pursuant to the procedures set forth in Exhibit D.

14.6 FORCE MAJEURE

         Neither Party shall be liable to the other for any delay or failure to
perform under this Agreement if the delay or failure to perform is without the
fault or negligence of the Party claiming excusable delay and is due to causes
beyond the control of said Party, including, but not limited to acts of God,
war, acts of the government, fires, floods, epidemics, quarantine restrictions,
strikes, labor disputes (including collective bargaining issues), work
stoppages, and freight embargoes.

14.7     GOVERNING LAW

directly or by implication, as an agent of the other Party or its affiliates or
in any manner assume or create, or attempt to assume or create, any obligations
on behalf of, or in the name of, the other Party unless so instructed by the
other Party in writing or allowed under this Agreement. Nothing herein is
intended or shall be construed to create any partnership or joint venture

CONFIDENTIAL                                                           05/14/99

INTRODUCTION

          This Statement of Work, executed by SCC Communications Corp, is for
          delivery of E9-1-1 data management services.

          SCC will be Client's agent and single point of contact for E9-1-1
          database management and for developing and maintaining the
          relationships necessary to provide the Client's customers optimum
          access to the 9-1-1 infrastructure. SCC will receive Service Order
          Input (SOI) records and validate them against the Master Street
          Address Guide (MSAG), correct records which are not MSAG valid, and
          distribute the SOI records for updates to the appropriate ALI Provider
          (such as an RBOC or other incumbent Independent Telephone Company).

PROJECT INITIATION

     PROGRAM MANAGEMENT

          SCC has designated a Program Manager to act as the primary interface
          between the two companies. Likewise, the Client will also designate a
          Program Manager to act as the primary interface between the two
          companies. The Program Managers shall be responsible for ensuring the
          successful achievement of project milestones as well as communicating
          project status within their respective organizations.

          The Program Managers shall work together to create an Implementation
          Plan within 30 days of contract signing. This Implementation Plan
          shall take into account key milestone dates to be achieved in the
          project. SCC will have responsibility for maintaining the
          Implementation Plan.

          SCC and the Client shall meet on a periodic basis either in person or
          through teleconferencing. Frequency of meetings shall be mutually
          agreed upon by the Program Managers. Each Party shall provide status
          on the work being performed in support of the Program. Mutually, the
          companies may elect to forego all or some of such meetings in lieu of
          periodic status reports.

          The Program Managers will maintain and distribute a list of key SCC
          and Client contacts (technical, operational, and managerial).

     9-1-1 COORDINATOR

          Client will appoint a 9-1-1 Coordinator who will serve as the primary
          SCC interface for "daily operations". This person is responsible for
          working with SCC in reporting/verifying problems, reviewing/rectifying
          error reports and performing system administrative duties (on Client
          side) such as data backups, archives, etc. This person will have
          primary responsibility for understanding SCC/Client 9-1-1 data
          processing, Methods and Procedures, and will facilitate ongoing
          communications with SCC (e.g. Quarterly Reviews).

     SERVICE PLANNING MEETINGS

          During the early stages of the project, the Program Managers will work
          together to determine the appropriate planning, design, and
          requirements definition meetings to be held to ensure successful
          delivery of E9-1-1 data management services.

          These planning sessions will be held with the Client's appropriate
          technical and operational groups to ensure a solid understanding of
          SCC data exchange procedures/requirements and daily operations.

     TRAINING

          SCC will provide up to two (2) days of 9-1-1 training concurrently to
          up to ten (10) designated Client 9-1-1 Coordinator(s) for working with
          SCC (data exchange procedures, data processing procedures, new market
          entry procedures, escalation procedures, etc.) Training will be
          conducted at SCC's headquarters in Boulder, Colorado.

          Additional training requested by Client (e.g. training for remote
          facilities) will be provided by SCC on a time and materials basis. SCC
          shall provide estimated costs in advance of incurring any expenses on
          Client's behalf and subject to Client's approval.

SERVICE IMPLEMENTATION

     DATA COMMUNICATION

          SCC will work with Client to determine the most appropriate method of
          electronic data communication. Depending on subscriber record volume,
          either Dedicated Circuit or Dial-Up connectivity may be selected.

          SCC and Client will establish a Primary and Secondary (Back-up)
          method of data communication. Typically, the Secondary method of data
          exchange will be Dial-Up connectivity (if Primary is Dedicated
          Circuit) or FAX (if Primary is Dial-Up). Data Communications
          requirements are detailed in SCC's "Data Exchange Guidelines"
          document.

          Client will bear data communications facilities costs from Client
          location to SCC. SCC will be responsible for identifying, and Client
          will be responsible for ordering, any required circuits and ensuring
          that the Program Managers are aware of any circuit installation and
          testing time requirements.

     DATA EXCHANGE REQUIREMENTS

          Data exchange requirements (Input and Output files with required data
          elements) are provided in SCC's "Data Exchange Guidelines" document
          detailing file specifications, service order process, data exchange
          requirements and file naming conventions.

     INITIAL MARKET AREA INFORMATION REQUIREMENTS

          Prior to initiating service in any market area, the Client agrees to
          provide SCC with the following:

          o    Market Areas (counties/communities served; required for MSAG
               validation)

          o    Approximate number of TNs in each Market Area

          o    All assigned NPA/NXX's and their associated Communities

          o    Letter of Agency that allows SCC to act on behalf of the Client
               to acquire MSAGs from host E9-1-1 database providers

     MSAG DATA MANAGEMENT

          SCC will work with the appropriate ALI Provider to obtain current
          MSAGs for all service areas identified by the Client. SCC utilizes
          these MSAGs to validate subscriber addresses on Client SOI data
          records as "MSAG correct" before transmitting E9-1-1 database updates
          to the appropriate ALI provider. SCC will refresh and update these
          MSAGs on a quarterly basis and will provide MSAGs in a standardized
          electronic data format conforming to "SCC's Guidelines for Data
          Exchange."

     METHODS & PROCEDURES

          To ensure a high and consistent level of service, SCC has developed
          Methods and Procedures to assist Client and SCC when handling specific
          9-1-1 data management activities. Methods and Procedures are developed
          as operational guidelines that identify the tasks, dependencies, and
          the responsibilities of all parties for the completion of specific
          activities.

          These Methods and Procedures will be reviewed with the Client's
          operations group during the early stages of the program.

          o    New Market Area Testing

          o    ANI/ALI Error Reporting & Resolution

          o    After Hours Problem Reporting

          o    Escalation Procedures

          o    Record Processing

          o    NPA Splits for ALECs

          o    Local Number Portability Data Processing

DAILY OPERATIONS

     SUBSCRIBER RECORD UPDATES (SERVICE ORDER INPUT "SOI" FILE)

          The largest volume of transactions processed by the NDSC fall into the
          category of subscriber record updates. These transactions are
          generated as a result of telephone customer requests for new telephone
          service or a change in their current service. Service Order Input
          "SOI" files are generated and transmitted to SCC's NDSC in NENA II
          format.

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

          As SOI files are received by the NDSC, SOI records are processed on
          the Transaction Services System (TSS) and matched against the E9-1-1
          reference databases (e.g. translation tables, MSAG, prefix tables,
          security tables, etc.). Valid SOI data is re-formatted into the
          appropriate format for distribution to the appropriate ALI Provider.

     ERROR PROCESSING

          SOI data not matching the specified and standardized parameters for
          valid E9-1-1 data fall out into a controlled, fully traceable error
          database in which errors are grouped based on date, type and area.

          SCC's standard practice is to correct only MSAG errors, i.e. "701"
          errors (House number out of range in MSAG) and "709" errors (Street
          not found in MSAG). These are the only errors for which SCC can access
          the appropriate data sources for accurate correction. These
          corrections are usually completed the same day of error notification.

          The Client will make every effort to supply error-free data to SCC.
          SCC will document the SCC action taken to correct MSAG errors in an
          ANNOTATED ERROR FILE (see "Data Exchange Guidelines" document).
          Annotated Error files are returned to Client within 24 hours of error
          detection (48 hours after SCC's receipt of SOI file). Client will be
          responsible for working with its end-user customers in resolving these
          errors. If there is a delay in the creation of the Annotated Error
          File, SCC will notify Client's 9-1-1 Coordinator.

     POST-PROCESSING ACKNOWLEDGMENT

          Once subscriber record update processing is complete, SCC returns
          Confirmation(s) and Statistics file(s) to the Client. The STATISTICS
          FILE contains the number of records received, the number of records
          processed without error, the number of records processed with errors,
          and the number of errors by type. The CONFIRMATIONS FILE contains a
          copy of each record sent to SCC as input (SOI file) in NENA II format.
          The Confirmations file contains an error/status field noting status of
          9-1-1 data processing.

          Records sent to ALI Providers are sent in a single batch file to each
          Provider. SCC routes these records to the appropriate recipient based
          on the following categories:

          o    SCC NDSC TSS System for Ameritech

          o    SCC NDSC TSS System for US West

          o    SCC NDSC TSS System for BellSouth

CONFIDENTIAL                                                           05/14/99

          o    Other Non-SCC ALI Provider systems (e.g. Pacific Bell, Bell
               Atlantic, GTE, NYNEX, Sprint, Southwestern Bell, Cincinnati Bell,
               Rochester Telephone, SNET)

          Records for each TSS system are processed separately after being
          parsed and routed from the original batch file. Thus, SCC returns a
          Statistics file and a Confirmations file from each TSS system. These
          Statistics and Confirmation files are traceable to the original batch
          file by the matching sequence number contained in the file names.

          The Confirmation files returned by SCC contain the NENA II record
          which includes a status/error field. If errors occurred while
          validating the records against the MSAG, SCC populates the
          status/error field of the NENA II record along with the appropriate
          status/error code (see SCC's "Data Exchange Guidelines" document).

          When no error occurs, the status/error field will contain a "000"
          (triple zero-confirmation that the records were successfully entered
          into host ALI database) for records processed on NDSC E9-1-1
          databases, and a "FWD" code (indicating the record validated against
          the MSAG and was successfully transmitted to the ALI Provider) for
          records transmitted to Non-NDSC E9-1-1 database providers.

     RECORD TRANSACTIONS AND HANDLING

          SCC will work with Client to determine the most appropriate method of
          electronic data communication. Depending on subscriber record volume,
          either Dedicated Circuit or Dial-Up connectivity may be selected.

          Under normal circumstances, error free records received electronically
          by 2:30pm MST, Monday through Friday are prepared and sent the same
          day to the host ALI provider using the standard data transmission
          procedures.

          THE FOLLOWING IS AN EXAMPLE OF A TRANSACTION:

          o    SCC receives SOI Records via a batch file in NENA II format

          o    Records are processed on SCC's Transaction Services System and
               validated against the appropriate MSAG.

          o    SCC produces a Statistics File and a Confirmation File with a
               "one to one" confirmation for every record sent in SOI file
               (status codes = "000", "FWD", or Error Code).

          o    Records with MSAG-related ("701" & "709") errors are time stamped
               and placed into the Error Queue for analysis and correction by
               SCC Data Analyst Unit.

          o    SCC resolves MSAG-related ("701" & "709") errors if possible.

          o    SCC produces an Annotated Error File detailing the action taken
               by SCC to correct MSAG-related errors.

          o    MSAG valid records are re-formatted per ALI Provider requirements
               and transmitted to ALI Provider per ALI Provider data processing
               windows.

          o    SCC archives daily Confirmation and Statistics Files.

     DATA PROCESSING INTERVALS

          With respect to non-facsimile, i.e., electronic file format;
          error-free transactions are processed within 24 hours of receipt. In
          regions where SCC maintains ALI records, error-free records are sent
          through SCC's TSS and updated in ALI within 24 hours, and for all
          other regions, SCC processes records against the appropriate MSAG in
          the TSS and prepares error-free records for transmission to the proper
          host LEC. In rare cases, routine processing may be suspended for
          special operations. These situations are coordinated in advance when
          possible. In any situation where data processing may be interrupted
          (e.g. Systems Maintenance, NPA Splits or Overlays), the Client's
          assigned 9-1-1 Coordinator will be notified. When known, SCC will
          provide Client with 72 hours advance notice.

     DATA EXCHANGE

          Except as otherwise provided herein regarding facsimile exchange of
          data during 1998, data (Input and Output files) will be exchanged per
          SCC's "Data Exchange Guidelines" document.

     NEW CLIENT MARKETS

          The Client shall provide SCC with a 45-day written notice for all
          prospective market entries. Client will also provide SCC with
          information as outlined in the "Initial Market Area Information
          Requirements" section of this Statement of Work.

MEASURING PERFORMANCE

     PERFORMANCE METRICS

          SCC applies a set of standard performance metrics to measure the
          E9-1-1 data management services provided to Client. Performance
          Metrics are provided to Client once a minimum level of 5000 subscriber
          records are under SCC management and are being exchanged in electronic
          file format. SCC requires a 90-day period after initiation of data
          management services to establish the first "baseline" set of Metrics.
          Metrics reports are supplied to Client on a monthly basis.

          The Primary Performance Metrics are:

          o    Elapsed Time to Post Service Order Updates

          o    Inbound Correctable Data Error Rates

          o    Error Resolution Interval by Class of Error

          o    Client Error Resolution Intervals

          The Primary Metrics are reported on a variety of criteria. Listed
          below are the Primary Metrics and the breakdowns used for each metric.
          Additionally, measurable performance standards are shown. Measurable
          standards for service order processing, error resolution intervals and
          error frequencies by error type define benchmarks against which SCC is
          assessed.

CONFIDENTIAL                                                            05/14/99

     PRIMARY METRIC I - ELAPSED TIME TO POST SERVICE ORDERS

          Definition:

          This metric is the elapsed time from the initial receipt of a valid
          service order until that order is processed on TSS and is transmitted
          to the appropriate ALI Provider.

          Performance Standard:

          The elapsed time to post SOI updates is less than twenty-four (24)
          hours.

          Direct Measurement of Quality

          98% of all service orders received are processed on a SCC NDSC E9-1-1
          database or are transmitted to the appropriate ALI Provider within 24
          hours of receipt.

     PRIMARY METRIC 2 - INBOUND CORRECTABLE DATA ERROR RATES

          Definition:

          The number of correctable data errors received compared to the total
          number of records received.

          Performance Standard:

          The routine reports are broken down by source state. SCC retains data
          records to support error analysis by telephone service provider, NPA
          NXX, and entity. These reports are run monthly to support error
          reduction efforts.

          Direct Measurement of Quality

          Inbound correctable error rates will not exceed 10% of the total
          service orders processed for a given time period.

     PRIMARY METRIC 3 - ERROR RESOLUTION BY CLASS OF ERROR

          Definition:

          This metric is defined as the elapsed time from when SCC receives an
          errant service order until the order is corrected and processed on the
          Transaction Services System.

          Performance Standard:

          SCC reports the resolution interval for the six most common error
          types. Since both parties contribute to the error resolution interval,
          each party commits to an on-going effort to shorten the time
          intervals.

          Direct Measurement of Quality

          The number of unresolved errors in any month are less than 0.2% of the
          total number of TNs in the database at the end of the month. Errors
          that cannot be resolved and are referred back to the Client for
          resolution are not included in this metric.

     PRIMARY METRIC 4 - ERROR RESOLUTION INTERVALS

          Definition:

          This metric is defined as the elapsed time from:

          a) When the Customer is notified of the existence of an uncorrectable
             error condition;

          b) Through the time when the Customer notifies SCC of the correct
             resolution to the problem.

          Performance Standard:

          Notification by SCC occurs within an average of 12 hours after
          identifying a problem requiring the Client's intervention. The
          Performance Standard for resolution of the problem shall be mutually
          agreed upon.

     QUARTERLY ALLIANCE PERFORMANCE REVIEWS

          While the Performance Metrics are reported to the appropriate
          personnel with a predefined frequency, the two companies will meet on
          a quarterly basis to formally review the performance of the alliance,
          end user customer feedback, upcoming major events, important industry
          trends, new government regulations, and the status of new product
          introduction plans. SCC will also present Client with process
          improvement recommendations intended to lower data errors and improve
          data quality.

          These review meetings shall alternate between SCC and the Client
          facilities (unless mutually agreed otherwise) and be attended by the
          appropriate operating management group of each company. The host
          company is responsible for the preparation of the agreed upon agenda.

     AUDITS

          SCC maintains a copy of all TN records submitted by the service order
          process including an audit trail for every transaction record. SCC
          will perform annual reconciliations of Client source data with ALI
          data for data residing on SCC's systems (NDSC regions). For non-NDSC
          regions, SCC will perform annual reconciliations or audits when Client
          has received the commitment and timeframe from the non-NDSC LEC to
          deliver to SCC an ALI extract file of Client data. Client will be
          responsible for procurement costs for acquiring the extract file from
          non-NDSC LECs.

          As part of SCC's standard Clearinghouse Services, SCC performs a
          detailed reconciliation of 50% of all Client data each year (based on
          number of TNs under SCC management). Reconciliations are staged
          throughout the year (approximately 12.5% each quarter); all data to
          complete the audit cycle every two (2) years. Problematic errors
          identified by either SCC or Client may be subject to more frequent
          reconciliations based on mutual agreement to do so. SCC understands
          the importance of the reconciliation process and the benefits to the
          integrity of the 9-1-1 data that is derived and will work with the
          Client in the prioritization and scheduling of reconciliations.

          SCC will provide Client with copies of reconciliation reports at the
          completion of regional reconciliations. Reconciliation reports will
          contain the number of records processed, number of discrepancies by
          type, discrepancy resolution status by record (either corrected or
          referred to Client).

CUSTOMER SUPPORT

     INTRODUCTION

          This support plan represents SCC's commitment to the ongoing support
          of the E9-1-1 Services being provided to Client and Client's
          customers. The following pages provide useful and important
          information for effective and efficient data management services
          support. This support plan includes:

               o an overview of SCC support plan activities

               o support contact procedures

               o assigned SCC points of contact

               o definitions of errors by severity level and correction
                 procedures

               o status reporting, and

               o notification and escalation procedures

     HOURS OF OPERATION

          SCC analysts provide data management services on a 12 hour (6:00 am to
          6:00 pm MST) by 5 day (Monday through Friday) basis. For emergency
          situations occurring outside of the 12x5 work hours, SCC will provide
          24 hour, seven days per week support services. The computer operations
          support staff are available at the NDSC facility around-the-clock for
          emergency services. NDSC management teams are also available via a
          nationwide radio pager network and supplemental staff are available in
          the event specialized services are required to respond to specific
          situations.

     OVERVIEW OF SUPPORT PLAN ACTIVITIES

          When 9-1-1 data problems arise, SCC provides prompt resolution
          assistance. For day to day data management and processing matters, the
          Client will always contact their designated SCC data analyst for
          problem resolution, communication and operational matters.

          The SCC data analyst is also the first point of contact for system or
          data communication problems that may be impacting the Client's ability
          to process service orders that occur within the normal workday. After
          business hours, critical problems as defined in the severity level
          descriptions below shall be reported to the NDSC Computer Operation's
          operator. The on-duty operator will assess the priority of the call,
          and when appropriate will page SCC personnel to request assistance for
          resolving an urgent problem.

          If a problem is determined to be the responsibility of Client or
          Client's customer (Client network, PSAP network, CPE, etc.), SCC
          will provide any available information to assist in the resolution of
          the problem. SCC expects that Client will have the same resolution
          time commitment for Severity Level 1 and 2 problems as are stated in
          this support plan.

          In the event the Client experiences a critical problem that either
          prohibits the transfer of service orders, or requires a backup or
          alternate processing method to be invoked, SCC should be notified,
          following the support contact procedures outlined below.

     SUPPORT CONTACT PROCEDURES

          Support is available 24 hours/day, 7 days/week, for reporting network
          problems, data communication issues or emergency ALI queries. Client
          will designate a primary contact person for working with SCC
          (generally the 9-1-1 Coordinator) personnel on support matters.

          SCC will log the call, problem description, and other pertinent
          information. SCC's response will coincide with the severity level of
          the call. Every attempt will be made to answer questions and provide
          resolution when the call is received, however, call back situations
          may occur particularly after normal business hours.

                    Examples of emergency situations that are supported by
                    computer operations staff, for NDSC provisioned systems, on
                    a 24-hour basis include:

                      o Network hardware, circuit, or ALI link failure

                      o ALI node failure on both sides of the PSAP

                      o Emergency ALI queries during dual ALI node failure

                    Computer operations staff can complete ALI lookup requests
                    for the NDSC provisioned ALI databases. ALI queries are
                    handled after hours on an emergency and exception basis and
                    in accordance to the operational procedures established by
                    the ALI host provider.

          On non-NDSC systems, computer operators can conduct TSS queries on an
          exception and emergency basis. SCC recognizes that the need of
          providing this service is infrequent and whenever possible, the ALI
          database is the absolute preferred source for such inquires. SCC will
          provide our customers with the methods and procedures for requesting
          emergency ALI or TSS queries.

          SCC only provides the emergency ALI or TSS lookup services to SCC
          clients. PSAPs will not be given access to this service.

     ERROR SEVERITY LEVELS & CORRECTION PROCEDURES

          SCC will correct errors and malfunctions in the service(s) that cause
          such service(s) either to be unavailable for use by Client or that
          materially fails to conform to the applicable specifications for such
          service(s) as described in the Client services agreement.

          Client may report errors to SCC either verbally or by written notice.
          Likewise, SCC may report errors detected by SCC personnel to Client
          either verbally or by written notice. If notice of the error is
          initially made verbally, the reporting party shall provide written
          notice (facsimile or electronic mail) within 24 hours of the initial
          verbal notification. Client shall use reasonable care to verify
          whether an error exists in, or is a result from, the service(s) prior
          to reporting such to SCC.

          The service(s) error correction procedures to be followed are
          dependent on the severity of the error as defined below. Each error
          severity level defines the actions that will be taken by SCC for
          Response Time, Resolution Time and Resolution Procedure.

     SEVERITY LEVEL 1

          DEFINITION: The E9-1-1 Database Services are severely and critically
          impaired, where major functions are completely inoperative and those
          major functions are critical to operation of the E9-1-1 Database
          Services.

          RESPONSE TIME: SCC will acknowledge the issue with a telephone
          conference call with Client within 30 minutes of Client's initial
          notification to SCC. SCC will notify Client of any service affecting
          errors within 30 minutes of the discovery of such errors

          RESOLUTION TIME: SCC will apply all reasonable efforts to provide a
          resolution within 6 hours of the notification from Client. If
          resolution cannot be provided within 6 hours, SCC will initiate the
          internal escalation procedure within the 6-hour period to ensure
          resources are appropriately assigned for problem resolution efforts.

          RESOLUTION: SCC will correct the service or provide a procedure for
          Client to bypass or work around the error condition in order to
          continue operations. If a bypass procedure is utilized, SCC will
          provide Client an acceptable action plan for the development of the
          final error correction activity and SCC will continue error resolution
          activity until full service is restored to Client.

                    Examples of Severity Level 1 conditions:

                      o Critical network or data communications error on an SCC
                        system that prevents us from receiving service order
                        files.

                      o TSS system failure that prohibits the processing of
                        service order files within the contractually defined
                        response times.

     SEVERITY LEVEL 2

          DEFINITION: The E9-1-1 Database Services are impaired and some
          functions are not operating, but those functions are not mandatory or
          critical to the operation of the E911 Database Services.

          RESPONSE TIME: SCC will respond with a telephone conference call with
          Client within 6 business hours of Client's initial notification of
          problem or error.

          RESOLUTION TIME: SCC will provide resolution within 14 days of the
          notification.

                    Examples of Severity Level 2 conditions:

                      o Unexpected character in a returned confirmation record

                      o Inability to post return reports or files for electronic
                        pick up by the customer.

                    RESOLUTION: SCC will correct the service or provide Client
                    with a procedure to bypass or work around the error
                    condition in order to continue operations. If a bypass
                    procedure is utilized, SCC will provide Client an acceptable
                    action plan for the development of the final error
                    resolution and SCC will continue error resolution activity
                    until full service is restored to Client.

          problems at intervals of not less than 4 hours to a designated Client
          representative. SCC shall provide verbal correction status reports on
          Severity Level 2 errors at intervals of not less than once per week to
          a designated Client representative.

          Client agrees to provide SCC, at the time of notification, all
          pertinent data requested by SCC to properly analyze an error
          condition. If SCC is unable to resolve the problem within the
          allotted resolution time due to a lack of data required to analyze the
          error condition, the internal Escalation Procedures defined below will
          be initiated. Client agrees to provide timely assistance if SCC
          requests additional information and data concerning the error
          condition.

          Each month, Client will provide SCC, not later than the 15th day of
          the relevant month, a list of Client's operating companies which
          report shall detail every NPA/NXX (area code and prefix) associated
          with each such company. Upon its receipt of such report in each such
          month, SCC will provide Client with a report reflecting the 9-1-1
          record counts (access lines), breaking out the NPA/NXX's for each
          Client operating company. SCC shall attach its report to the monthly
          invoice rendered by SCC pursuant to Exhibit B.

     NOTIFICATION AND ESCALATION PROCEDURES

          SCC will provide Client with a notification document that includes a
          listing of key SCC employees by function, telephone numbers and
          24-hour pager numbers. This information is provided to Client in case
          an extraordinary situation develops that requires immediate
          notification. The Client will provide SCC with a similar list of
          contact numbers for emergency situations. It is the responsibility of
          each party to update and publish these lists on a regular basis.

          In conjunction with the notification process, SCC will provide for
          escalation processes within the standard guidelines set forth in the
          Clearinghouse Services Methods and Procedures.

                   SCC COMMUNICATIONS CLEARINGHOUSE SERVICES

These escalation procedures are intended as a guideline for ensuring problems
are addressed and resolved in a timely fashion. SCC appreciates Client's
cooperation in abiding by these guidelines.

CLIENT - PROCEDURE

     1.   Client personnel reports a problem to the SCC Clearinghouse Services
          Analyst, relaying pertinent information for initial analysis.

     2.   Depending on the nature of the problem, it may require up to 24 hours
          to resolve the problem. Problem resolution may require more than 24
          hours if resolution depends on other agencies such as the host ALI
          database provider or county coordinator. Client personnel continue to
          monitor the trouble and provide additional information necessary for
          resolution.

     3.   If Client does not receive response to --or- resolution of a severity
          level 1 or 2 problem within the times specified in the Statement of
          Work, the Client may invoke escalation procedures.

          o Client invokes escalation procedures by contacting the Clearinghouse
            Services Supervisor.

          o If Clearinghouse Services Supervisor does not respond or provide
            resolution to problem within 4 hours, Client may escalate to
            Clearinghouse Services Manager.

          o If Clearinghouse Services Manager does not respond or provide
            resolution to problem within 24 hours, Client may escalate to Vice
            President, NDSC Operations.

THIS LEASE, which is effective as of the date set forth in the Basic Lease
Information, is entered by Landlord and Tenant, as set forth in the Basic Lease
Information. Terms which are capitalized in this Lease shall have the meanings
set forth in the Basic Lease Information.

1.      PREMISES.

        Landlord leases to Tenant, and Tenant leases from Landlord, the Premises
        described in the Basic Lease Information, together with the right in
        common to use the Common Areas of the Building and the Property (as
        shown in Exhibit A). The Common Areas shall mean the areas and
        facilities within the Building and the Property provided and designated
        by Landlord for the general use, convenience or benefit of Tenant and
        other tenants and occupants of the Building (e.g., restroom's;
        janitorial, telephone and electrical closets; and unreserved parking
        areas). Landlord reserves the right to enlarge, reduce, change or
        otherwise alter the Common Areas of the Building and the Property at any
        time during the term of this Lease. In addition, Landlord shall have the
        right to close temporarily any portion of the Common Areas to make
        repairs or changes or to prevent the acquisition of public rights in the
        Common Areas. [SEE ADDENDUM]


2.      TERM.

        a.      Lease Term. The Term of this Lease shall commence on the
                Commencement Date (as defined in Subsection 2.b.) and, unless
                terminated on an earlier date in accordance with the terms of
                this Lease, shall extend for the period (i.e., Term) specified
                in the Basic Lease Information.

        b.      Commencement Date. The "Commencement Date" of this Lease shall
                be the earliest to occur of the following, as reasonably
                determined by Landlord: [Intentionally deleted] [SEE ADDENDUM]

        c.      Premises Not Delivered. If, for any reason, Landlord cannot
                deliver possession of the Premises to Tenant by the Estimated
                Commencement Date (as set forth in the Basic Lease Information),
                (i) Tenant shall not be obligated to pay Rent until the
                Commencement Date; (ii) the Term shall not be extended; (iii)
                the failure shall not affect the validity of this Lease, or the
                obligations of Tenant under this Lease; and (iv) Landlord shall
                not be subject to any liability.

        d.      Commencement Date Memorandum. When the Commencement Date is
                determined, the parties shall execute a Commencement Date
                Memorandum, in the form attached hereto as Exhibit C, setting
                forth the Commencement Date and the expiration date ("Expiration
                Date") of this Lease. [SEE ADDENDUM]

        e.      Early Entry. If Tenant is permitted to enter the Premises prior
                to the Commencement Date for the purposes of fixturing or any
                purpose other than occupancy permitted by Landlord, the entry
                shall be subject to all the terms and provisions of this Lease,
                except that the payment of Rent shall commence as of the
                Commencement Date.

        f.      Adjustment for Calendar Month. If the Commencement Date is not
                the first day of a calendar month, the Term shall be deemed to
                have commenced on the first day of the next succeeding calendar
                month, for purposes of determining any and all renewal dates,
                the Expiration Date, notice periods for any options, the
                effective date of any increases in Rent (defined in Section 3),
                and any other provisions relating to the Term.

3.      RENT.

        a.      Definitions. As used in this Lease, the term "Rent" shall
                include: (i) the Base Rent; (ii) Tenant's Percentage Share of
                the total dollar increase, if any, in the Operating Expenses
                paid or incurred by Landlord during the calendar year over the
                Operating Expenses paid or incurred by Landlord during the Base
                Year (as set forth in the Basic Lease Information), and (iii)
                all other amounts which Tenant is obligated to pay under the
                terms of this Lease. All amounts of money payable by Tenant to
                Landlord shall be paid without prior notice or demand, deduction
                or offset. If any installment of Rent is not paid by the fifth
                (5th) day of the month, Tenant shall pay to Landlord a late
                payment charge equal to five percent (5%) of the amount of the
                delinquent installment, in addition to the installment of Rent
                then owing, regardless of whether a notice of default or notice
                of termination has been given by Landlord. In addition to the
                five percent (5%) late charge, any Rent or other amounts owing
                hereunder which are not paid within five (5) days after the date
                they are due shall thereafter bear interest at the rate
                ("Interest Rate") which is the [*]. [SEE ADDENDUM]

        b.      Accord and Satisfaction. No payment by Tenant or receipt by
                Landlord of a lesser amount than any installment or payment of
                Rent due shall be deemed to be other than on account of the
                amount due, and no endorsement or statement on any check or
                payment of Rent shall be deemed an accord and satisfaction.
                Landlord may accept such check or payment without prejudice to
                Landlord's right to recover the balance of such installment or
                payment of Rent, or pursue any other remedies available to
                Landlord. [SEE ADDENDUM]

4.      BASE RENT.

        a.      Initial Base Rent. Tenant shall pay Base Rent to Landlord (or
                other entity designated by Landlord), in advance, on the first
                day of each calendar month of the Term, at Landlord's address
                for notices (as set forth in the Basic Lease Information) or at
                such other address as Landlord may designate. The Initial Base
                Rent shall be the amount set forth in the Basic Lease
                Information. Upon executing this Lease, Tenant shall pay an
                amount equal to the monthly Base Rent stated on the Basic Lease
                Information, which shall be credited against the Base Rent due
                at the beginning of the Term. [SEE ADDENDUM]

                Operating Expenses paid or incurred by Landlord during the
                calendar year over the Operating Expenses paid or incurred by
                Landlord during the Base Year.

        b.      Operating Expenses. The term "Operating Expenses" shall include
                all reasonable expenses and costs of every kind and nature which
                Landlord shall pay or become obligated to pay because of or in
                connection with the ownership and operation of the Building,
                Common Areas and Premises, surrounding property and supporting
                facilities. Operating Expenses shall include, without

                relating to the Building, Common Areas and Premises as set forth
                in Sections 13.b., 13.d. and 13.h.; (iii) wages, salaries and
                related expenses and benefits of all on-site and off-site

                Buildings; (ix) all maintenance costs relating to the Building
                and Common Areas, including sidewalks, landscaping, service

                ADDENDUM]

        c.      Monthly Increments; Adjustment. Prior to the commencement of
                each of Landlord's accounting years, Landlord shall estimate the

                accounting year pursuant to

<PAGE>   6
                this Section. Tenant shall pay to Landlord, on the first of each
                month, in advance, one-twelfth (1/12) of Landlord's estimate.
                Within ninety (90) days after (or as soon thereafter as
                possible) the close of each accounting year after which this
                Lease remains in effect, Landlord shall provide Tenant with a
                statement [Intentionally deleted]. Landlord, in Landlord's sole
                discretion, shall have the right to reduce the Operating
                Expenses to limit the impact (e.g., year to year fluctuations)
                resulting from extraordinary or unusual expenses or costs. If
                Tenant has overpaid the amount of Operating Expenses owing
                pursuant to this Section, Landlord shall credit the overpayment
                to Tenant within thirty (30) days after Tenant's receipt of
                Landlord's statement; provided, however, that the Rent owed by
                Tenant shall never be less than the Base Rent stated in Section
                4. If Tenant has underpaid the amount of Operating Expenses
                owing pursuant to this Section, Tenant shall pay the amount of
                the underpayment to Landlord, as Additional Rent, within thirty
                (30) days after Tenant's receipt of Landlord's statement. If
                less than one hundred percent (100%) of the rentable area of the
                Building is occupied, Operating Expenses shall be adjusted to
                equal Landlord's reasonable estimate of Operating Expenses if
                one hundred percent (100%) of the total rentable area of the
                Building were occupied. [SEE ADDENDUM]

                alteration in, on or about the Premises without the prior
                written consent of Landlord, which consent shall not be
                unreasonably withheld or delayed. Tenant shall comply with all
                rules, laws, ordinances and requirements at the time Tenant
                makes any alteration and shall deliver to Landlord a complete
                set of "as built" plans and specifications for each alteration.
                Tenant shall be solely responsible for maintenance and repair of
                all alterations made by Tenant. As used in this Section 9, the
                term "alteration" shall include any alteration, addition or
                improvement. [SEE ADDENDUM]

        b.      Liens. If, because of any act or omission of Tenant or anyone
                claiming by, through, or under Tenant, any mechanic's lien or
                other lien is filed against the Premises, the Building, the
                Property or against other property of Landlord (whether or not
                the lien is valid or enforceable), Tenant shall, at its own
                expense, cause it to be discharged of record within a reasonable
                time, not to exceed [intentionally deleted] days, after the date
                of the filing. In addition, Tenant shall defend and indemnify
                Landlord and hold it harmless from any and all claims, losses,
                damages, judgments, settlements, costs and expenses, including
                attorneys' fees, resulting from the lien. [SEE ADDENDUM]

        c.      Ownership of Alterations. Any alteration made by Tenant shall
                immediately become Landlord's property. Except as provided in
                Subsection 9.d., Landlord may require Tenant, at Tenant's sole
                expense and by the end of the Term, to remove any alterations
                made by Tenant and to restore the Premises to its condition
                prior to the alteration. [SEE ADDENDUM]

        d.      Request Regarding Removal Obligation. At the time that Tenant
                requests Landlord's consent to any alteration, Tenant may

                Tenant, at Tenant's sole expense, to remove any or all of the
                alteration by the end of the Term, and to restore the Premises
                to its condition prior to the alteration.

        telecommunication risers and cabling, in good condition and repair;
        ordinary wear and tear, damage by fire, earthquake, acts of God or the

        expense of Landlord or in lieu thereof to vacate the Premises as
        provided in California Civil Code Section 1942 or any other law, statute
        or ordinance now or hereafter in effect. [SEE ADDENDUM]

11.     DAMAGE OR DESTRUCTION.

        a.      Landlord's Obligation to Rebuild. If the Premises are damaged or
                destroyed, Landlord shall promptly and diligently repair the
                Premises unless Landlord has the option to terminate this Lease
                as provided herein, and Landlord elects to terminate.

        b.      Right to Terminate. Landlord shall have the option to terminate
                this Lease if the Premises or the Building is destroyed or
                damaged by fire or other casualty, regardless of whether the
                casualty is insured against under this Lease, if Landlord
                reasonably determines that the repair of the Premises or the
                Building cannot be completed within two hundred seventy (270)
                days after the [intentionally deleted] casualty. If Landlord
                desires to exercise the right to terminate this Lease as a
                result of a casualty, Landlord shall exercise the right by
                giving Tenant written notice of its election to terminate within
                thirty (30) days after the, in which event this Lease shall
                terminate fifteen (15) days after the date of the notice. If
                Landlord does not exercise the right to terminate this Lease,
                Landlord shall promptly commence the process of obtaining
                necessary permits and approvals, and shall commence repair of
                the Premises or the Building as soon as practicable and
                thereafter prosecute the repair diligently to completion, in
                which event this Lease shall continue in full force and effect.
                [SEE ADDENDUM]

        c.      Limited Obligation to Repair. Landlord's obligation, should
                Landlord elect or be obligated to repair or rebuild, shall be
                limited to the Building shell and any tenant improvements which
                are constructed and paid for by Landlord pursuant to Exhibit B.
                Tenant, at its option and expense, shall replace or fully repair
                all trade fixtures, equipment and other improvements, including
                all telecommunication risers and cabling, installed by Tenant
                and existing at the time of the damage or destruction.

        d.      Abatement of Rent. In the event of any damage or destruction to
                the Premises which does not result in termination of this Lease,
                the Base Rent shall be temporarily abated proportionately to the
                degree the Premises are untenantable as a result of the damage
                or destruction, commencing from the date of the damage or
                destruction and continuing during the period required by
                Landlord to substantially complete its repair and restoration of
                the Premises; provided, however, that nothing herein shall
                preclude Landlord from being entitled to collect the full amount
                of any rent loss insurance proceeds. Tenant shall not be
                entitled to any compensation or damages from Landlord for loss
                of the use of the Premises, damage to Tenant's personal property
                or any inconvenience occasioned by any damage, repair or
                restoration. Tenant hereby waives the provisions of Section
                1932, Subdivision 2, and Section 1933, Subdivision 4, of the
                California Civil Code, and the provisions of any similar law
                hereafter enacted.

        e.      Damage Near End of Term and Extensive Damage. In addition to the
                rights to termination under Subsection 11.b., Landlord shall
                have the right to cancel and terminate this Lease as of the date
                of the occurrence of destruction or damage if the Premises or
                the Building is [intentionally deleted] made untenantable during
                the last twelve (12) months of the Term. Landlord shall give
                notice of its election to terminate this Lease under this
                Subsection 11.e. within thirty (30) days after Landlord
                determines that the damage or destruction would require more
                than six (6) months to repair. If Landlord does not elect to
                terminate this Lease, the repair of the damage shall be governed
                by Subsection 11.a. or 11.b., as the case may be. [SEE ADDENDUM]

               f. Insurance Proceeds. If this Lease is terminated, Landlord may
               keep all the insurance proceeds resulting from the damage, except
               for those proceeds which specifically insured Tenant's personal
               property and trade fixtures. [SEE ADDENDUM]

12.     EMINENT DOMAIN.

        If all or any part of the Premises is taken for public or quasi-public
        use by a governmental authority under the power of eminent domain or is
        conveyed to a governmental authority in lieu of such taking, and if
        [intentionally deleted] the taking or conveyance causes the remaining
        part of the Premises to be untenantable and inadequate for use by Tenant
        for the purpose for which they were leased, then Tenant, at its option
        and by giving written notice within fifteen (15) days after the taking,
        may terminate this Lease as of the date Tenant is required to surrender
        possession of the Premises. If a part of the Premises is taken or
        conveyed but the remaining part is tenantable and


                                       5
<PAGE>   9

        adequate for Tenant's use, then this Lease shall be terminated as to the
        part taken or conveyed as of the date Tenant surrenders possession;
        Landlord shall make such repairs, alterations and improvements as may be
        necessary to render the part not taken or conveyed tenantable; and the
        Rent shall be reduced in proportion to the part of the Premises taken or
        conveyed. All compensation awarded for the taking or conveyance shall be
        the property of Landlord without any deduction therefrom for any estate
        of Tenant, and Tenant hereby assigns to Landlord all its right, title
        and interest in and to the award. Tenant shall have the right, however,
        to recover from the governmental authority, but not from Landlord, such
        compensation as may be awarded to Tenant on account of the interruption
        of Tenant's business, moving and relocation expenses and removal of
        Tenant's trade fixtures and personal property.

13.     INDEMNITY AND INSURANCE.

        a.      Indemnity. Tenant shall be responsible for, shall insure
                against, and shall indemnify Landlord and its constituent parts

                damage or injury to person or property occurring in, on or about
                the Premises, and Tenant hereby releases Landlord and its
                constituent parts from any and all liability for the same.
                Tenant's obligation to indemnify Landlord and its constituent
                parts hereunder shall include the duty to defend against any
                claims asserted by reason of any loss, damage or injury, and to
                pay any judgments, settlements, costs, fees and expenses,
                including attorneys' fees, incurred in connection therewith with
                counsel reasonably acceptable to Landlord. [SEE ADDENDUM]

        b.      Fire and Extended Coverage. Landlord shall procure and maintain
                in full force and effect with respect to the Building a policy
                or policies of all risk or "Special Term" insurance for the full
                insurance replacement value thereof.

        c.      Public Liability. Tenant, at its own cost and expense, shall
                keep and maintain in full force and effect during the Term a
                policy or policies of commercial general public liability
                insurance, written by an insurance company approved by Landlord,
                in the form customary to the locality, insuring Tenant's
                activities with respect to the Premises and/or the Building
                against loss, damage or liability for personal injury or death
                of any person or loss or damage to property occurring in, upon
                or about the Premises, covering bodily injury in the amounts of
                Two Million Dollars ($2,000,000) per person and Two Million
                Dollars ($2,000,000) per occurrence, and covering property
                damage in the amount of One Million Dollars ($1,000,000);
                provided, however, that if, at any time during the Term, Tenant
                shall have in full force and effect a blanket policy of public
                liability insurance with the same coverage for the Premises as
                described above, as well as coverage of other premises and
                properties of Tenant, or in which Tenant has some interest, the
                blanket insurance shall satisfy the requirement hereof.

        d.      Rental Abatement Insurance. Landlord may keep and maintain in
                full force and effect during the Term rental abatement insurance
                against abatement or loss of Rent in case of fire or other
                casualty, in an amount at least equal to the amount of Rent
                payable by Tenant during one (1) year of the Term, as reasonably
                determined by Landlord.

        e.      Insurance Certificates. Tenant shall furnish to Landlord, upon
                the Commencement Date and thereafter within thirty (30) days
                prior to the expiration of each policy, a certificate of
                insurance issued by the insurance carrier of each policy of
                insurance carried by Tenant pursuant to this Section 13. The
                certificates shall expressly provide that the policies shall not
                be cancelable or subject to reduction of coverage or otherwise
                be subject to modification except after thirty (30) days' prior
                written notice to the parties named as additional insured.
                Landlord, its successors and assigns, and any nominee of
                Landlord holding any interest in the Premises, including,
                without limitation, any ground lessor or the holder of any fee
                or leasehold mortgage, shall be named as an additional insured
                under each policy of insurance maintained by Tenant pursuant to
                this Lease.

        f.      Tenant's Failure. Tenant's failure to maintain any insurance
                required by this Lease, shall be a default hereunder, and Tenant
                shall be liable for any loss or costs resulting from the
                failure.

        g.      Tenant's Property and Fixtures. Tenant shall assume the risk of
                theft or damage to any furniture, equipment, machinery, goods,
                supplies or fixtures which are or remain the property of Tenant,
                or as to which Tenant retains the right of removal from the
                Premises.

        h.      Earthquake and Flood Insurance. In addition to any other
                insurance policies carried by Landlord in connection with the
                Building, Landlord may elect to procure and maintain in full
                force and effect during the Term with respect to the Building a
                policy of earthquake/volcanic action and flood and/or surface
                water insurance, including rental value insurance against
                abatement or loss of rent in the case of damage or loss covered
                under the earthquake/volcanic and flood and/or surface water
                insurance, in an amount equal to one hundred percent (100%) of
                the full insurance replacement value (including debris removal
                and demolition) of the Building. [SEE ADDENDUM]

14.     ASSIGNMENT OR SUBLET.

        If Tenant desires to assign this Lease or to sublet the Premises, or any
        part thereof, Tenant shall give to Landlord written notice of its intent
        at least [Intentionally deleted] days in advance of the date on which
        Tenant desires to assign or sublet the Premises. Landlord shall have
        thirty (30) days after receipt of Tenant's written notice within which
        to notify Tenant in writing that Landlord elects to [Intentionally
        deleted] permit Tenant to assign this Lease or sublease the Premises,
        subject, however, to Landlord's prior written approval, which approval
        shall not be unreasonably withheld. Landlord and Tenant agree that it
        shall be reasonable for Landlord to withhold its consent if Landlord
        reasonably determines that the proposed assignee or sublessee (A) does
        not have the financial ability to fulfill all of the obligations of
        Tenant under this Lease, (B) is to use Hazardous Substances in type or
        quantity in excess of those used by Tenant, (C) will potentially
        increase the Operating Expenses, (D) is a governmental entity,
        [Intentionally deleted]. Upon any proposed assignment or sublet, Tenant
        shall enter into a written agreement with Landlord requiring that
        [Intentionally deleted] of the excess moneys due to Tenant under the
        assignment or sublet over the Rent to be required to be paid by Tenant
        hereunder shall be paid to Landlord. No consent by Landlord to any
        assignment or sublet shall be deemed to be a consent to a use not
        permitted under this Lease, to any act in violation of this Lease or to
        any subsequent assignment or sublet. No assignment or sublet by Tenant
        shall relieve Tenant of any obligation under this Lease. Any attempted
        assignment or sublet by Tenant in violation of the terms and covenants
        of this Section shall be void. [SEE ADDENDUM]


15.     DEFAULT.

        a.      Tenant's Default. At the option of Landlord, a material breach
                of this Lease by Tenant shall exist if any of the following
                events (severally, "Event of Default"; collectively, "Events of
                Default") shall occur: (i) if Tenant shall have failed to pay
                Rent, including Tenant's Percentage Share of increased Operating
                Expenses, or any other sum required to be paid hereunder
                [Intentionally deleted], together with interest at the Interest
                Rate, from the date the amount became due through the date of
                payment, inclusive; (ii) if Tenant shall have failed to perform
                any term, covenant or condition of this Lease except those
                requiring the payment of money, and Tenant shall have failed to
                cure the breach within [Intentionally deleted] days after
                written notice from Landlord if the breach could reasonably be
                cured within the [Intentionally deleted] day period; provided,
                however, if the failure could not reasonably be cured within the
                [Intentionally deleted] day period, then Tenant shall not be in
                default unless it has failed to promptly commence and thereafter
                continue to make diligent and reasonable efforts to cure the
                failure as soon as practicable as reasonably determined by
                Landlord; (iii) if Tenant shall have its assets for the benefit
                of its creditors; (iv) if the [Intentionally deleted]
                sequestration of, attachment of, or execution on, any material
                part of the property of Tenant or on any property essential to
                the conduct of Tenant's business shall have occurred, and Tenant
                shall have failed to obtain a return or release of the property
                within thirty (30) days thereafter, or prior to sale pursuant to
                any sequestration, attachment or levy, whichever is earlier; (v)
                if Tenant shall have [Intentionally deleted] abandoned
                [Intentionally deleted] the Premises; (vi) if a court shall have
                made or entered any decree or order adjudging Tenant to be
                insolvent, or approving as properly filed a petition seeking
                reorganization of Tenant, or directing the winding up or
                liquidation of Tenant, and the decree or order shall have
                continued for a period of thirty (30) days; (vii) if Tenant
                shall make or suffer any transfer which constitutes a fraudulent
                or otherwise avoidable transfer under any provision of the
                federal Bankruptcy Laws or any applicable state law; or (viii)
                if Tenant shall have failed to comply with the provisions of
                Sections 23 or 25 of this Lease. An Event of Default shall
                constitute a default under this Lease. [SEE ADDENDUM]

        b.      Remedies Upon Tenant's Default. Upon an Event of Default,
                Landlord shall have the following remedies, in addition to all
                other rights and remedies provided by law, equity, statute or
                otherwise provided in this Lease, to which Landlord may resort
                cumulatively or in the alternative:

                (i)     Landlord may continue this Lease in full force and
                        effect, and this Lease shall continue in full force and
                        effect as long as Landlord does not terminate Tenant's
                        right to possession, and Landlord shall have the right
                        to collect Rent when due [Intentionally deleted]. No act
                        by Landlord allowed by this Subsection (i) shall
                        terminate this Lease unless Landlord notifies Tenant in
                        writing that Landlord elects to terminate this Lease.
                        [SEE ADDENDUM]

                (ii)    Landlord may terminate Tenant's right to possession of
                        the Premises at any time by giving written notice to
                        that effect. No act by Landlord other than giving
                        written notice to Tenant shall terminate this Lease.
                        Acts of

<PAGE>   11

                        maintenance, efforts to relet the Premises or the
                        appointment of a receiver on Landlord's initiative to
                        protect Landlord's interest under this Lease shall not
                        constitute a termination of Tenant's right to
                        possession. On termination, Landlord shall have the
                        right to remove all personal property of Tenant and
                        store it at Tenant's cost and to recover from Tenant as
                        damages: (a) the worth at the time of award of unpaid
                        Rent and other sums due and payable which had been
                        earned at the time of termination; plus (b) the worth at
                        the time of award of the amount by which the unpaid Rent
                        and other sums due and payable which would have been
                        payable after termination until the time of award
                        exceeds the amount of the Rent loss that Tenant proves
                        could have been reasonably avoided; plus (c) the worth
                        at the time of award of the amount by which the unpaid
                        Rent and other sums due and payable for the balance of
                        the Term after the time of award exceeds the amount of
                        the Rent loss that Tenant proves could be reasonably
                        avoided; plus (d) any other amount necessary to
                        compensate Landlord for all the detriment proximately
                        caused by Tenant's failure to perform Tenant's
                        obligations under this Lease, or which, in the ordinary
                        course of things, would be likely to result therefrom,
                        including, without limitation, any costs or expenses
                        incurred by Landlord: (1) in retaking possession of the
                        Premises, including reasonable attorneys' fees and costs
                        therefor; (2) maintaining or preserving the Premises for
                        reletting to a new tenant, including repairs or
                        alterations to the Premises for the reletting; (3)
                        leasing commissions; (4) any other costs necessary or
                        appropriate to relet the Premises; and (5) at Landlord's
                        election, such other amounts in addition to or in lieu
                        of the foregoing as may be permitted from time to time
                        by the laws of the State of California.

                        The "worth at the time of award" of the amounts referred
                        to in Subsections (ii)(a) and (ii)(b) is computed by
                        allowing interest at the lesser of [Intentionally
                        deleted] per annum or the maximum rate permitted by law,
                        on the unpaid Rent and other sums due and payable from
                        the termination date through the date of award. The
                        "worth at the time of award" of the amount referred to
                        in Subsection (ii)(c) is computed by discounting the
                        amount at the discount rate of the Federal Reserve Bank
                        of San Francisco at the time of award, plus one percent
                        (1%). Tenant waives redemption or relief from forfeiture
                        under California Code of Civil Procedure Sections 1174
                        and 1179, or under any other present or future law, if
                        Tenant is evicted or Landlord takes possession of the
                        Premises by reason of any default of Tenant hereunder.
                        [SEE ADDENDUM]

      c.    Landlord's Default. Landlord shall not be deemed to be in default in
            the performance of any obligation required to be performed by
            Landlord hereunder unless and until Landlord has failed to perform
            the obligation within thirty (30) days after receipt of written
            notice by Tenant to Landlord specifying wherein Landlord has failed
            to perform the obligation; provided, however, that if the nature of
            Landlord's obligation is such that more than thirty (30) days are
            required for its performance, then Landlord shall not be deemed to
            be in default if Landlord shall commence the performance within the
            thirty (30) day period and thereafter shall diligently prosecute the
            same to completion.

16.   LANDLORD'S RIGHT TO PERFORM TENANT'S COVENANTS.

      If Tenant shall at any time fail to make any payment or perform any other
      act on its part to be made or performed under this Lease, Landlord may,
      but shall not be obligated to, make the payment or perform any other act
      to the extent Landlord may deem desirable and, in connection therewith,
      pay expenses and employ counsel. Any payment or performance by Landlord
      shall not waive or release Tenant from any obligations of Tenant under
      this Lease. All sums so paid by Landlord, and all penalties, interest and
      costs in connection therewith, shall be due and payable by Tenant on the
      next day after any payment by Landlord, together with interest thereon at
      the Interest Rate, from that date to the date of payment thereof by Tenant
      to Landlord, plus collection costs and attorneys' fees. Landlord shall
      have the same rights and remedies for the nonpayment thereof as in the
      case of default in the payment of Rent. [SEE ADDENDUM]

17.   SECURITY DEPOSIT.

      Tenant has deposited with Landlord the Security Deposit, in the amount
      specified in the Basic Lease Information, as security for the full and
      faithful performance of every provision of this Lease to be performed by
      Tenant. If Tenant defaults with respect to any provision of this Lease,
      Landlord may use, apply or retain all or any part of the Security Deposit
      for the payment of any Rent or other sum in default, for the payment of
      any amount which Landlord may expend or become obligated to expend by
      reason of Tenant's default, or to compensate Landlord for any loss or
      damage which Landlord may suffer by reason of Tenant's default. If any
      portion of the Security Deposit is used or applied, Tenant shall deposit
      with Landlord, within ten (10) days after written demand therefor, cash in
      an amount sufficient to restore the Security Deposit to its original
      amount. Landlord shall not be required to keep the Security Deposit
      separate from its general funds. [Intentionally deleted] [SEE ADDENDUM]


18.   SURRENDER OF PREMISES.

      By taking possession of the Premises, Tenant shall be deemed to have
      accepted the Premises, Building, and the Property in good, clean
      [Intentionally deleted] condition [Intentionally deleted]. On the
      expiration or early termination of this


                                       8
<PAGE>   12

      Lease, Tenant shall surrender the Premises to Landlord in its condition as
      of the Commencement Date, normal wear and tear excepted. Tenant shall
      remove from the Premises all of Tenant's personal property, trade fixtures
      and any alterations required to be removed pursuant to Section 9 of this
      Lease. Tenant shall repair damage or perform any restoration work required
      by the removal. If Tenant fails to remove any personal property, trade
      fixtures or alterations after the end of the Term, Landlord may remove the
      property and store it at Tenant's expense, including interest at the
      Interest Rate. If the Premises are not so surrendered at the termination
      of this Lease, Tenant shall indemnify Landlord against all loss or
      liability resulting from delay by Tenant in so surrendering the Premises,
      including, without limitation, any claims made by any succeeding tenant,
      losses to Landlord due to lost opportunities to lease to succeeding
      tenants, and attorneys' fees and costs. [SEE ADDENDUM]

19.   HOLDING OVER.

      If Tenant remains in possession of all or any part of the Premises after
      the expiration of the Term or the termination of this Lease, the tenancy
      shall be month-to-month only and shall not constitute a renewal or
      extension for any further term. In such event, Base Rent shall be
      increased in an amount equal to [*] of the Base Rent during the last month
      of the Term (including any extensions), and any other sums due under this
      Lease shall be payable in the amount, and at the times, specified in this
      Lease. The month-to-month tenancy shall be subject to every other term,
      condition, covenant and agreement contained in this Lease and Tenant shall
      vacate the Premises immediately upon Landlord's request. [SEE ADDENDUM]

20.   ACCESS TO PREMISES.

      Tenant shall permit Landlord and its agents to enter the Premises at all
      reasonable times, to inspect the Premises; to post Notices of
      Nonresponsibility and similar notices and to show the Premises to
      interested parties such as prospective mortgagors, purchasers and tenants;
      to make necessary alterations, additions, improvements or repairs either
      to the Premises, the Building, or other premises within the Building; and
      to discharge Tenant's obligations hereunder when Tenant has failed to do
      so within a reasonable time after written notice from Landlord. The above
      rights are subject to reasonable security regulations of Tenant, and to
      the requirement that Landlord shall at all times act in a manner to cause
      the least possible interference with Tenant's operations. [SEE ADDENDUM]

21.   SIGNS.

      The size, design, color, location and other physical aspects of any sign
      in or on the Building shall be subject to the CC&R's (if applicable),
      Rules, Landlord's approval prior to installation, and to any appropriate
      municipal or other governmental approvals. The costs of any permitted
      sign, and the costs of its installation, maintenance and removal, shall be
      at Tenant's sole expense and shall be paid within ten (10) days of
      Tenant's receipt of a bill from Landlord for the costs. [SEE ADDENDUM]

22.   WAIVER OF SUBROGATION.

      Anything in this Lease to the contrary notwithstanding, Landlord and
      Tenant each hereby waives and releases the other of and from any and all
      rights of recovery, claim, action or cause of action against the other,
      its subsidiaries, directors, agents, officers and employees, for any loss
      or damage that may occur in the Premises, the Building or the Property; to
      improvements to the Building or personal property (building contents)
      within the Building; or to any furniture, equipment, machinery, goods and
      supplies not covered by this Lease which Tenant may bring or obtain upon
      the Premises or any additional improvements which Tenant may construct on
      the Premises by reason of fire, the elements or any other cause which is
      required to be insured against under this Lease, regardless of cause or
      origin, including negligence of Landlord or Tenant and their agents,
      subsidiaries, directors, officers and employees, to the extent insured
      against under the terms of any insurance policies carried by Landlord or
      Tenant and in force at the time of any such damage, [Intentionally
      deleted]. Because this Section 22 will preclude the assignment of any
      claim mentioned in it by way of subrogation or otherwise to an insurance
      company or any other person, each party to this Lease agrees immediately
      to give to each of its insurance companies written notice of the terms of
      the mutual waivers contained in this Section 22 and to have the insurance
      policies properly endorsed, if necessary, to prevent the invalidation of

HAZARDOUS MATERIALS SITE ASSESSMENT
STONEY POINT ROAD PARCELS
SANTA ROSA, CALIFORNIA

This letter presents the results of a hazardous materials site assessment
conducted by Harding Lawson Associates (HLA) for an approximate 20-acre site
located at the intersection of West 9th Street and Stony Point Road in Santa
Rosa, California (Plate 1). The purpose of the assessment was to evaluate
whether past or present generation, use, storage or disposal of hazardous
materials occurred on the site and/or adjacent properties and whether such
materials could impact site development and/or require mitigation.

SCOPE OF SERVICES

To evaluate the potential impact of hazardous materials on the site, HLA's
investigation consisted of the following:

- -    Reviewing documents and aerial photographs related to historical
     development of the site and adjacent property.

- -    Contacting appropriate regulatory agencies for hazardous materials
     information concerning the site and the surrounding area located
     approximately within one-quarter mile of site boundaries; inquiries were
     made regarding documentation of toxic spills, underground tanks, the use,
     storage, disposal and/or generation of hazardous materials, and violations
     of applicable environmental control standards.

- -    Reviewing selected reports for information pertaining to soil and
     ground-water contamination.

- -    Conducting an on-site inspection and off-site reconnaissance to identify
     visible evidence of hazardous materials generation, use, storage, spills
     or disposal.

- -    Evaluating findings and preparing this report.

SITE DESCRIPTION

The site consists of four adjacent parcels of land near the intersection of
West 9th Street and Stony Point Road. The southern most parcel, AP Number
10-320-22, is a triangular piece of property bounded by West 9th Street to the
northwest, Stoney Point Road to the southwest, and existing residential
developments to the east. The southern tip of this property is adjacent to
Santa Rosa Creek. The remaining three parcels, A.P. Numbers 10-320-25, 26, and
27 comprise on continuous, irregularly shaped property, which is bounded by West
9th Street to the southwest, Stony Point Road to the southwest, undeveloped City
of Santa Rosa owned property to the northwest, and residential developments to
the north and east. All parcels are currently undeveloped and covered with
dried, volunteer grasses. The parcels are relatively flat, with the exception of
an approximately 5 foot high beam constructed adjacent to Stony Point Road and
West 9th Street on the irregularly shaped property.

SITE HISTORY

The study area, which includes the site and the surrounding areas, were used
for agricultural endeavor until the 1960s. Agriculture activity included the
growing of annual crops and fruit orchards. Since the end of agricultural
activities in the mid-1960s, the site has remained vacant and unused.
Development of the surrounding areas began in the 1950s with the construction of
Santa Rosa's wastewater treatment facility on West College Avenue. Two storage
ponds, which store an approximate 55 acre feet of treated wastewater, were built
at this time. Further development in the surrounding areas occurred during the
late 1960s and early 1970s. During this time, Stony Point Road, which previously
ended south of Santa Rosa Creek, was continued to the intersection of West
College Avenue and Marlow Road, approximately 1/4-mile northwest of the site.
Construction of residential subdivisions east of the property commenced during
this time period and continued through the 1970s. Stony Point West Business
Park, located west of the site, was constructed in the early 1980s.

AERIAL PHOTOGRAPH REVIEW

Historical and current land uses of the site and adjacent areas were reviewed
by examining aerial photographs at the Sonoma County Assessor's Office and at
Pacific Aerial Surveys in Oakland. Aerial photographs were taken in 1961, 1971,
1980, and 1986.

In the May 1961 photograph, the site and surrounding areas are either orchards
or plowed. The Santa Rosa Waste Water Plant is the only major development in
the area.

Photographs in May 1971 show Stony Point Road completed along the site's
southwest property line. Agricultural activities at the site and adjacent areas
appear to have ended by this time. Initial grading for the residential
development east of the site is also shown. Photographs taken in July 1980 and
April 1986 show continued development of the surrounding residential areas and
construction of Stony Point Business Park on the southwest side of Stony Point
Road.

ON-SITE INSPECTION

An on-site inspection was performed by an HLA representative on August 17,
1988, to identify visual signs of potential liability related to improper
dumping of hazardous materials, surface impoundments, abandoned drums, or the
presence of aboveground or underground storage tanks. No visual signs of
potential contamination of any consequence were noted.

Small quantities of landscaping debris, consisting mainly of lawn cuttings,
were present on the northern property. Additionally, stockpiles of soil were
also present in the same area. Conversations with Mr. James Brecht indicate
that this soil was placed during construction the Stony Point Business Park,
southwest of Stony Point Road.

OFF-SITE RECONNAISSANCE

Reconnaissance of the area within 1/4-mile of the site was performed on August
17, 1988. No sources of hazardous materials in the form of storage tanks,
spills, or manufacturing processes that use hazardous materials were
identified. No businesses that might generate significant quantities of toxic
or hazardous materials are within 1/4-mile of the site.

AGENCY DISCUSSIONS

The following agency representatives were contacted regarding their knowledge
of potential or known environmental concerns at the site or surrounding
properties.

- -     Janet Naito
      California Department of Health Services (DOHS), Emeryville
      Phone No.: 415/540-2043        Date: August 25, 1988

- -     Luis Rivera
      Regional Water Quality Control Board (RWQCB), North Coast Division
      Phone No.: 707/576-2220        Date: August 25, 1988

Conversations with personnel from the RWQCB and SRU indicate that the
wastewater ponds west of the site do not contain hazardous materials. These
ponds contain treated sewage and serve as storage ponds for irrigation water.
Treatment of wastewater at this plant occurs only during times of heavy
rainfall. Such events create wastewater in-flows which exceed the capacity of
the main treatment plant on Liano Road and require the use of the west college
facility for wastewater treatment.

CONCLUSIONS

Based on review of agency records, conversations with agency personnel, review
of in-house documents, and the site visit, there is no indication of obvious
hazardous or industrial waste contamination which may impact site development.

We trust that this is the information you require at this time. If you have any
questions, please call.

Yours very truly,

First Union National Bank,
  as Administrative Agent
One First Union Center, TW-10
301 South College Street
Charlotte, NC 38288-0608


Ladies and Gentlemen:

     This letter acknowledged that the undersigned (the "Landlord") have been
informed that _________________ (the "Tenant"), has entered into a Credit

loans and other financial accommodations to the Tenant under the Credit
Agreement (the "Loans"), the Lenders require, among other things, liens on the
Tenant's personal property, including, without limitation equipment, and trade
fixtures (the "Personal Property").

     To induce the Lenders to continue to make the Loans and provide financial
accommodations to the Tenant, and for other good and valuable considerations,
the receipt and sufficiency of which are hereby acknowledged, the Landlord
hereby represents and warrants to the Administrative Agent that as of the date
hereof:

     1.   The Landlord is the current landlord under the lease described in
Exhibit A attached hereto (the "Lease") with the Tenant;

     2.   The Lease is in full force and effect and there have been no
amendments, modifications or other agreements relating to the Lease except as
stated herein;

     3.   To Landlord's actual knowledge, Tenant is not in default under the

time or both would constitute a default or a breach by Tenant of the terms and
conditions of the Lease; and

     4.   The Tenant is the tenant under the Lease, and, to the Landlord
actual knowledge, is in full compliance with the covenants, agreements and
obligations under the Lease.

     The Landlord agrees that: (a) the Tenant (or its representatives) is the
owner of the Personal Property located at or on the Premises (as defined in the
Lease) whether attached to the Premises or not; (b) the Administrative Agent's
lien upon or security interest in the Personal Property is prior and superior
to any interest, lien or claim of any nature the Landlord may now have or
hereafter

<PAGE>   39
obtain in the Personal Property whether by operation of law, contract or
otherwise; (c) either the Tenant or the Administrative Agent may remove the
Personal Property from the Premises without hindrance on the part of the
Landlord subject to the conditions set forth herein. Upon not less than ten (10)
days' written request, the Landlord will grant the Administrative Agent (or its
representatives) access to the Premises so that the Administrative Agent (or its
representatives) may remove the Personal Property, provided that (1) the
Administrative Agent, on its own behalf and on behalf of the Lenders,
indemnifies and holds Landlord harmless from any claims, losses, liability,
costs or damages (including reasonable attorneys' fees) incurred by Landlord in
connection with the removal of the Personal Property by the Administrative Agent
and the Administrative Agent's entry on the Premises or Landlord's property, (2)
the Administrative Agent shall restore the Premises to its condition existing
immediately prior to the installation of the Personal Property removed by the
Administrative Agent, (3) in no event shall the Administrative Agent commit, or
permit to be committed, any damage to the Premises or any improvement of which
the Premises are a part, and (4) the Administrative Agent shall not conduct any
sales or auctions on the Premises; and (d) the Personal Property shall remain
personal property (to the extent such Personal Property is not already a fixture
as of the date hereof) and shall not become fixtures, notwithstanding the manner
or mode of the attachment of the Personal Property to the land. Landlord may
require that the Administrative Agent be accompanied by a representative of
Landlord when entering the Premises. The Landlord hereby waives any rights it
may now or hereafter have in the Personal Property, including without
limitation, any lien rights available under applicable law.

     The Landlord understands that the Administrative Agent and the Lenders
will rely on this Landlord Waiver and Estoppel Certificate in continuing to make
Loans and provide financial accommodations to the Tenant.

relating to the applicable calendar year. Any such audit must be conducted by
Tenant or its agent during regular business hours at the offices of Landlord or
the offices of Landlord's designated agent and must be completed within sixty
(60) days after Tenant notifies Landlord in writing of its election to audit the
applicable year end statement. The person or entity performing the audit or
review of Landlord's books and records on Tenant's behalf or at Tenant's request
may not be compensated for the audit or review on a contingency basis. If
Landlord objects to the findings of Tenant's audit, Landlord and Tenant shall
attempt to resolve their disagreement concerning the amount of Tenant's
proportionate share of Operating Expenses within the next thirty (30) days. If
Landlord and Tenant are unable to agree upon the amount of Tenant's

management or accounting or, alternatively,

or Court of Appeal. The matter shall be decided by arbitration in accordance
with the applicable arbitration statutes and the then existing Commercial
Arbitration Rules of the American Arbitration Association. Any party may
initiate the arbitration procedure by delivering a written notice of demand for
arbitration to the other party. Within thirty (30) days after the other party's
receipt of the written notice of demand for arbitration, the parties shall
attempt to select a qualified arbitrator who is acceptable to all parties. If
the parties are unable to agree upon an arbitrator who is acceptable to all
parties, either party may request the American Arbitration Association to
appoint the arbitrator in accordance with its Commercial Arbitration Rules. The
provisions of California Code of Civil Procedure Section 1283.05 or its
successor section(s) are incorporated in and made a part of this Lease with
respect to any arbitration requested in accordance with the provisions contained
in this Section. Depositions may be taken and discovery may be obtained in any
arbitration proceeding requested pursuant to this Section in accordance with the
provisions of California Code of Civil Procedure Section 1283.05 or its
successor section(s). Arbitration hearing(s) shall be conducted in Sonoma
County, California. Any relevant evidence, including hearsay, shall be admitted
by the arbitrator if it is the sort of evidence upon which responsible persons
are accustomed to rely in the conduct of serious affairs, regardless of the
admissibility of such evidence in a court of law; however, the arbitrator shall
apply California law relating to privileges and work product. In rendering his
or her award, the arbitrator shall set forth the reasons for his or her
decision. The fees and expenses of the arbitrator shall be paid in the manner
allocated by the arbitrator. This agreement to arbitrate any dispute concerning
the findings of Tenant's audit shall be specifically enforceable under the
prevailing arbitration law. Judgment on the award rendered by the award may be
entered in any court having jurisdiction thereof. If, as a result of Tenant's
audit, the parties determine that Landlord has overstated Tenant's percentage
share of the Operating Expenses by more than five percent (5%) during the
applicable calendar year, Landlord shall reimburse Tenant for the reasonable
cost of the audit."

        assignment or sublease, Landlord and Tenant agree that it shall be
        reasonable for Landlord to withhold its consent in any one (1) or more
        of the following situations: (1) in Landlord's reasonable judgment, the
        proposed subtenant or assignee or the proposed use of the Premises would
        detract from the status of the Building, generate vehicle or foot
        traffic, parking or occupancy density materially in excess of the amount

        elevator, janitorial, security or other Building services (e.g., HVAC,
        trash disposal and sanitary sewer flows) than is customary for the
        Building; (2) in Landlord's reasonable judgment, the creditworthiness of
        the proposed subtenant or assignee does not meet the credit standards
        applied by Landlord in considering other tenants for the lease of space
        in the Building on comparable terms, or

        Tenant has failed to provide Landlord with reasonable proof of the
        creditworthiness of the proposed subtenant or assignee; (3) in
        Landlord's reasonable judgment, the business history, experience or
        reputation in the community of the proposed subtenant or assignee does
        not meet the standards applied by Landlord in considering other tenants
        for occupancy in the Building; (4) the proposed assignee or subtenant is
        a governmental entity, agency or department or the United States Post
        Office; or (5) the proposed subtenant or assignee is a then existing or
        prospective tenant of the Building.

        d. EXECUTED AGREEMENT. No sublease or assignment shall be valid, nor
        shall any subtenant or assignee take possession of the Premises, until a
        fully executed counterpart of the sublease or assignment has been
        delivered to Landlord and Landlord, Tenant and the applicable assignee
        or subtenant have entered into a consent to assignment or sublease in a
        form reasonably acceptable to Landlord.

        e. WAIVER. Notwithstanding any assignment or sublease, or any
        indulgences, waivers or extensions of time granted by Landlord to any
        assignee or sublessee, or failure by Landlord to take action against any
        assignee or sublessee, Tenant waives notice of any default of any
        assignee or sublessee and agrees that Landlord may, at its option,
        proceed against Tenant without having taken action against or joined
        such assignee or subleases, except that Tenant shall have the benefit of
        any indulgences, waivers and extensions of time granted to any such
        assignee or sublessee.

        f. NO CONSENT REQUIRED. Notwithstanding anything to the contrary
        contained in this Lease, Tenant may, without Landlord's prior written
        consent, and without being subject to any bonus rent provisions, sublet
        the Premises or assign the Lease to (i) a subsidiary or parent
        corporation controlling, controlled by or under common control with
        Tenant, (ii) a successor corporation by merger, consolidation,
        nonbankruptcy reorganization or government action, or (iii) a purchaser
        of all or substantially all of Tenant's assets. In addition, the sale of
        Tenant's capital stock through a private or public offering shall not be
        deemed to be an assignment for purposes of this Lease."

        The following Sections are incorporated into this Lease:

        "40. Option to Lease Additional Space.

        a. Grant of Option. Provided that Tenant is not in default under the
        terms of this Lease beyond any applicable notice and cure period, during
        the period commencing on the date of this Lease and ending on the
        Commencement Date (the "Option Term"), Landlord grants to Tenant the
        option (the "Option") to lease



                                       13
<PAGE>   53

        additional space on the ground floor of the Building subject to the
        terms and conditions provided below.

        b. Commencement of Option. If at any time during the Option Term
        Landlord proposes to lease to a bona-fide third party (i) more than
        fifty percent (50%) of the total rentable square footage of space on the
        ground floor of the Building or (ii) a portion of the rentable square
        footage of space on the ground floor of the Building which, when added
        to the rentable square footage of space on the ground floor of the
        Building previously leased by Landlord to a third party other than
        Tenant, would equal fifty percent (50%) or more of the total rentable
        square footage of space on the ground floor of the Building, Landlord
        shall notify Tenant in writing ("Landlord's Option Notice") of such
        event. Landlord's Option Notice shall state both (i) the amount of space
        which Landlord proposes to lease to the third party (the "Offered
        Space") and (ii) the total amount of space which is then available for
        lease on the ground floor of the Building (the "Aggregate Available
        Space").

        c. Exercise of Right. Tenant shall have ten (10) days after Landlord
        delivers to Tenant Landlord's Option Notice in which to notify Landlord
        in writing of Tenant's election to lease either the Offered Space or the
        Aggregate Available Space on all of the terms and conditions set forth
        in this Lease, except (i) the term of Tenant's lease of the Offered
        Space or the Aggregate Available Space, as applicable, shall commence on
        the date Landlord delivers possession of the Offered Space or Aggregate
        Available Space to Tenant and shall expire on the date upon which the
        term of this Lease expires, (ii) Landlord shall not be obligated to
        perform any work in the Offered Space or the Aggregate Available Space,
        and (iii) Landlord shall not be obligated to construct any tenant
        improvements in the Offered Space or the Aggregate Available Space, and
        (iv) Landlord shall provide Tenant with a tenant improvement allowance
        in an amount equal to [*] per rentable square foot for general purpose
        office improvements constructed in the Offered Space or the Aggregate
        Available Space. If Tenant fails to notify Landlord in writing of its
        election to lease either the Offered Space or the Aggregate Available
        Space within the ten (10) day period referenced above, then (a) Tenant's
        Option shall terminate and be of no further force or effect and (b)
        Landlord shall have the right to lease the Offered Space or the
        Aggregate Available Space to any person or entity other than Tenant.

        d. Amendment. Within fourteen (14) days after Tenant exercises its
        Option, Landlord and Tenant shall amend this Lease to include the
        Offered Space or the Aggregate Available Space, as applicable, as part
        of the Premises.

        41.   Right of First Offer.

        a. Right of Tenant. Provided that Tenant is not in default under the
        terms of this Lease beyond any applicable notice and cure period, during
        the period commencing on September 1, 1999 and continuing until the
        expiration (and not

        including any extensions) or earlier termination of this Lease (the
        "Right of First Offer Term"), Tenant shall have a right of first offer
        to lease any Additional Space Increment. The Additional Space Increments
        subject to this right of first offer shall not include any space which
        is subject to expansion or extension rights of then existing tenants.

        b. Commencement of Right. If at any time during the Right of First Offer
        Term Landlord desires to offer to lease an Additional Space Increment to
        a third party tenant, Landlord shall notify Tenant in writing
        ("Landlord's Offer Notice") of Landlord's intent to lease the Additional
        Space Increment which notice shall specify all of the terms upon which
        Landlord proposes to lease the Additional Space Increment to Tenant
        (with the remainder of the terms to be those set forth in this Lease,
        but excluding any obligation for Landlord to perform any work in the
        Additional Space Increment, construct any tenant improvements or provide
        Tenant with any tenant improvement allowance).

        c. Exercise of Right. Tenant shall have ten (10) days after Tenant's
        receipt of Landlord's Offer Notice in which to notify Landlord in
        writing ("Tenant's Offer Notice") of its election to lease the
        Additional Space Increment on the terms set forth in Landlord's Offer
        Notice. If Tenant accepts Landlord's offer, the parties shall amend this
        Lease to add the Additional Space Increment as part of the Premises
        within fourteen (14) days after Tenant accepts Landlord's offer. If
        Tenant fails to deliver Tenant's Offer Notice to Landlord within the ten
        (10) day period referenced above, or Landlord and Tenant fail to enter
        into a lease for the Additional Space Increment within fourteen (14)
        days after Tenant delivers Tenant's Offer Notice to Landlord, then
        Tenant's rights under this Section 41 with respect to the Additional
        Space Increment shall terminate and be of no further force or effect.

        42. Right to Extend Term.

        a. Grant. Landlord hereby grants to Tenant one (1) option (the "Option")
        to extend the term of this Lease, for an additional period of five (5)
        years (the "Option Term"), commencing when the original Term expires,
        upon the terms and conditions set forth in this Section 43. Tenant shall
        exercise the Option (if at all) by giving Landlord written notice of its
        election no earlier than three hundred sixty-five (365) days prior to
        the expiration of the original Term and no later than one hundred eighty
        (180) days' prior to the expiration of the original Term. Tenant shall
        not have the right to exercise the Option if Tenant is in default under
        the terms of this Lease. In addition, at Landlord's election, Tenant's
        exercise of the Option shall be null and void if Tenant is in default
        under the terms of this Lease as of the commencement of the Option Term.

        b. Base Rent. If this Option is exercised, the Base Rent for the
        Premises shall be [*] of the then current fair market monthly rent
        ("Fair Market Rent") for the Premises as of the commencement date of the
        Option Term, as determined by the agreement of the parties or, if the
        parties cannot agree

        within one hundred twenty (120) days prior to the commencement of the
        Option Term, then by an appraisal. All other terms and conditions
        contained in the Lease and this Addendum, as the same may be amended
        from time to time by the parties in accordance with the provisions of
        the Lease, shall remain in full force and effect and shall apply during
        the Option Term (except that Tenant shall have no further options to
        extend the Term).

        c. Appraisal. If it becomes necessary to determine the Base Rent for the
        Premises during the Option Term by appraisal, then, on or before the one
        hundred tenth (110th) day prior to the expiration of the original Term,
        Landlord and Tenant shall each deliver to the other party a written
        notice setting forth its good faith estimate of the Base Rent for the
        Premises during the Option Term (collectively referred to as the
        "Estimates"). If the higher of such Estimates is not more than one
        hundred five percent (105%) of the lower of such Estimates, then the
        Base Rent for the Premises during the Option Term shall be the average
        of the two (2) Estimates. If the Base Rent for the Premises during the
        Option Term is not resolved by the exchange of Estimates, Landlord and
        Tenant, within ten (10) days after the exchange of Estimates, shall each
        select an appraiser to determine which of the two (2) Estimates most
        closely reflects a Base Rent that is [*] of the Fair Market Rent. Each
        appraiser so selected shall be certified as an MAI appraiser or as an
        ASA appraiser and shall have had at least five (5) years experience
        within the previous ten (10) years as a real estate appraiser working in
        the Santa Rosa area, with working knowledge of current rental rates and
        practices. For purposes of this Lease, an "MAI" appraiser means an
        individual who holds an MAI designation conferred by, and is an
        independent member of, the American Institute of Real Estate Appraisers
        (or its successor organization, or in the event the is no successor
        organization, the organization and designation most similar), and an
        "ASA" appraiser means an individual who holds the Senior Member
        designation conferred by, and is an independent member of, the American
        Society of Appraisers (or its successor organization, or in the event
        there is no successor organization, the organization and designation
        most similar). Upon selection, Landlord's and Tenant's appraisers shall
        work together in good faith to agree upon which of the two (2) Estimates
        most closely reflects a Base Rent that is [*] of the Fair Market Rent.
        The Estimate chosen by such appraisers shall be binding on both Landlord
        and Tenant. If either Landlord or Tenant fails to appoint an appraiser
        within the ten (10) day period referred to above, the appraiser
        appointed by the other party shall be the sole appraiser for the
        purposes hereof. If the two (2) appraisers cannot agree upon which of
        the two (2) Estimates most closely reflects a Base Rent that is [*] of
        the Fair Market Rent within the twenty (20) days after their
        appointment, then, within ten (10) days after the expiration of such
        twenty (20) day period, the two (2) appraisers shall select a third
        appraiser meeting the aforementioned criteria. Once the third appraiser
        has been selected as provided for above, then, as soon thereafter as
        practicable but in any case within fourteen (14) days thereafter, the
        appraiser shall make a determination of which of the two (2) Estimates
        most closely reflects a Base Rent that is [*] of the Fair Market Rent
        and such Estimate shall be binding on both Landlord and

        Tenant. The parties shall share equally in the costs of the third
        arbitrator and of any experts retained by the third arbitrator. Any fees
        of any appraiser, counsel or experts engaged directly by Landlord or
        Tenant, however, shall be borne by the party retaining such appraiser,
        counsel or expert. In the event that the Base Rent for the Option Term
        has not been determined by the commencement of the Option Term, Tenant
        shall pay Base Rent upon the same terms and conditions in effect
        immediately prior to the Option Term until such time as the Base Rent
        for the Option Term has been determined. Upon such determination, the
        Base Rent for the Premises during the Option Term shall be retroactively
        adjusted to commencement of the Option Term. Upon the determination of
        the Base Rent for the Premises for the Option Term, Landlord and Tenant
        shall enter into a letter agreement to memorialize the agreement. If
        such adjustment results in an underpayment of Base Rent by Tenant,
        Tenant shall pay Landlord the amount of such underpayment within thirty
        (30) days after the determination thereof.

        d. Fair Market Rent. For purposes hereof, "Fair Market Rent" shall mean
        the arms length fair market annual rental rate per rentable square foot
        under new leases (excluding renewals) entered into on or about the date
        on which the Fair Market Rent is being determined hereunder for space
        comparable to the Premises in the Building and office buildings
        comparable to the Building. The determination of Fair Market Rent shall
        take into account any material economic differences between the terms of
        this Lease and any comparison lease, such as rent abatements,
        construction costs, tenant improvement allowances, brokerage commissions
        (or the absence thereof), and different base years, and other
        concessions, and the manner, if any, in which the Landlord, under any
        such lease is reimbursed for operating expenses and taxes. The
        determination of Fair Market Rent shall take into consideration any
        reasonably anticipated changes in the Fair Market Rent from the time
        such Fair Market Rent is being determined and the time such Fair Market
        Rent will become effective under this Lease.

        43. Dish/Antenna.

        a. Right to Install. During the term of this Lease, Tenant shall have
        the right to install, maintain and operate a satellite dish or roof-top
        antenna (the "Dish/Antenna") on the roof of the Building subject to
        Landlord's and Landlord's architect's and/or engineer's approval of
        Tenant's plans and specifications for the Dish/Antenna, the manner in
        which the Dish/Antenna is to be attached to the roof of the Building,
        and the manner in which any cables are run to and from the Dish/Antenna,
        such approval not to be unreasonably withheld. Landlord shall designate
        the exact location on the roof where the Dish/Antenna is to be located.
        Landlord, at its sole cost and expense, reserves the right to relocate
        the Dish/Antenna to another location on the roof of the Building at any
        time during the term of this Lease. Tenant shall be solely responsible
        for obtaining all of the necessary governmental and regulatory approvals
        with respect to the installation and operation of the Dish/Antenna and
        for the cost of installing, operating, maintaining and removing the
        Dish/Antenna.



                                       17
<PAGE>   57

        b. Interference. Tenant agrees to only install equipment of types and
        frequencies which will not cause unreasonable interference to Landlord
        or any other tenants of the Building. If Tenant's equipment causes such
        interference, Tenant will change the frequency on which it transmits
        and/or receives and take any other steps necessary to eliminate the
        interference. If the interference cannot be eliminated within a
        reasonable period of time in Landlord's reasonable judgment, Tenant
        shall remove the Dish/Antenna from the Building.

        c. Maintenance. Tenant shall, at its sole cost and expense and at its
        sole risk, install, operate and maintain the Dish/Antenna in a good and
        workmanlike manner, and in compliance with all Building electric,
        communication and safety codes, laws, ordinances, standards, regulations
        and requirements, now in effect or hereafter promulgated.

        d. Removal. Tenant shall remove the Dish/Antenna at its own expense at
        the expiration or earlier termination of this Lease. Tenant shall repair
        any damage caused by Tenant's removal of the Dish/Antenna, including the
        patching of any holes to match, as closely as possible, the color
        surrounding the area where the equipment and appurtenances were
        attached.

        e. Exclusive Right. Provided that Tenant is not in default under the
        terms of this Lease beyond any applicable notice and cure period,
        Landlord shall not lease space on the roof of the Building to a provider
        of telecommunication, video, data or related services ("Communication
        Services") who is not a tenant in the Building for the purposes of
        providing Communication Services to unaffiliated tenants, occupants or
        licensees of another building.

        44. Landlord Estoppel. Within ten (10) days after Tenant's written
        request, Landlord shall execute the Landlord Waiver and Estoppel
        Certificate attached hereto as Exhibit G or such other documents
        reasonably acceptable to Landlord to evidence Landlord's waiver of any
        right, title, lien or interest in Tenant's personal property, equipment
        and trade fixtures (collectively, "Tenant's Personal Property") and give
        Tenant's lenders holding a security interest or lien on Tenant's
        Personal Property reasonable rights or access to the Premises to remove
        such personal property; provided, however, Landlord's waiver of its lien
        and grant of access to Tenant's lenders shall be subject to and
        conditioned upon the lender agreeing in writing (i) to indemnify, defend
        and hold harmless Landlord from any and all claims, losses, liability,
        costs or damages (including reasonable attorneys' fees) incurred by
        Landlord in connection with the lender's removal of Tenant's Personal
        Property and entry on the Premises or Landlord's property, (ii) to
        restore any portion of the Premises damaged by such lender's removal of
        Tenant's Personal Property to its condition existing immediately prior
        to the installation of the Tenant's Personal Property, (3) not to damage
        any portion of the Premises or any improvement of which the Premises are
        a part, and (4) not to conduct any sales or auctions on the Premises.

                      TELECOMMUNICATIONS SERVICES AGREEMENT


        This Telecommunications Services Agreement is entered into as of March

1.      INCORPORATION OF DOCUMENTS AND CONTROLLING PROVISIONS:

1.1     This Service Agreement, together with (a) Service Orders (as defined in
        Section 2.1 of this Service Agreement) accepted by Qwest pursuant to the
        terms hereof, and (b) schedules and exhibits incorporated herein by
        reference ("Exhibits"), shall be referred to collectively herein as this
        "TSA" or this "Agreement". In the event of any conflict between the
        provisions of this TSA and the terms of any Service Order(s) and/or
        Exhibit(s), the conflict shall be resolved by reference to said
        documents in the following order of priority of interpretation (except
        as is otherwise specifically provided in this TSA or in any Exhibits):
        (a) this TSA; (b) any Exhibit(s), with reference to the same in order of
        attachment to this TSA; and (c) any Service Order(s). Notwithstanding
        the foregoing, no provision or term of any Service Order or Exhibit
        shall be a part of this TSA or binding on Qwest unless and until such
        Service Order or document has been executed by an authorized
        representative of Qwest.

1.2     If any provision of this TSA conflicts with any statute, rule or order
        of any governmental unit or regulatory body, or tariff filed by Qwest,
        then, if required by law, this TSA shall remain in effect but shall be
        automatically modified by such conflicting law, statute, rule, order or
        tariff, subject to the termination rights granted herein.

2.      SERVICES TO BE PROVIDED BY QWEST:

2.1     Services and Facilities available from Qwest are identified in the
        service and pricing Exhibit(s) attached hereto, which are incorporated
        by this reference. Services or Facilities requested by Customer shall be
        requested on Qwest's service order forms in effect from time to time
        (hereafter, any such order is a "Service Order(s)"). Each Service Order
        shall become a part of this TSA when executed by a duly authorized
        representative of Qwest. Qwest reserves the right to reject any Service
        Order.

2.2     Upon acceptance by Qwest of a Service Order, and during the Term (as
        defined in Section 4 of this TSA), Qwest shall provide to Customer those
        Services or Facilities (as defined in the attached Exhibits) identified
        in the Service Order.

3.      OBLIGATIONS OF CUSTOMER:

        outlined in the attached Exhibits, in addition to those described herein
        and in any Service Order(s).

3.2     Customer shall have sole responsibility for installation, testing and
        operation of facilities, services and equipment other than those
        Services or Facilities specifically provided by Qwest under this TSA
        (the "Customer Facilities").

3.3     Customer shall fully comply with all laws, regulations and authorities
        including, but not limited to, those outlined in Section 9 of this TSA.

4.      TERM:

4.1     This TSA shall be effective between the parties as of the date first
        written hereon. The initial term (the "INITIAL TERM") of this TSA shall
        expire seven (7) years from the date of execution hereof unless either
        party earlier terminates this TSA in the manner provided herein.

4.2     Upon the expiration of the Initial Term, if Customer is not then in
        default hereunder, the term of this TSA shall be renewed automatically
        on a month-to-month basis ("Renewal Term") unless an Amendment is
        executed by the parties extending the Renewal Term, or either party
        terminates this TSA in the manner provided herein.

4.3     The Initial Term and Renewal Term are sometimes referred to together
        herein as the "Term".

4.4     Notwithstanding anything to the contrary in this Section 4, if the
        Facility Minimum Service Term (as defined in Section 4.2 of Exhibit A)
        for any Facility extends beyond the expiration of the Term of this TSA,
        this TSA shall remain in effect until the expiration or termination of
        the applicable Facility Minimum Service Term, but only as to such
        Facility so affected, and subject to the termination rights of Qwest and
        Customer under Section 8 of this TSA.

5.      CHARGES AND PAYMENT:

5.1     Charges for Services and Facilities shall be determined in accordance
        with the Service and Pricing Exhibit(s).

5.2     Switched services charges shall be invoiced by Qwest on a monthly basis
        in arrears.

                          Confidential and Proprietary

                                        2
<PAGE>   6

        in advance and non-recurring charges shall be invoiced in arrears. If
        the Start of Service Date (as defined in Section 2.1 of Exhibit A) for
        any Facility falls on a day other than the first day of any month, the
        first invoice to Customer shall consist of: (1) the pro-rata portion of
        the applicable monthly charge covering the period from the Start of
        Service Date to the first day of the subsequent month, and (2) the
        monthly charge for the following month.

5.4     Customer shall make all payments due hereunder within thirty (30) days
        of the date of invoice. If any amount due under this TSA is not received
        by the due date, in addition to other remedies available hereunder,
        Qwest may in its sole discretion: (a) impose a late payment charge of
        the lower of [*] per month or the highest rate legally permissible (such
        late charge shall be payable upon demand by Qwest); and/or (b) require
        the prepayment of up to [*] of recurring charges as a condition of the
        continued availability of the Services or Facilities, which prepayment
        shall be held and applied against [*] of charges hereunder prior to
        termination of this TSA. Notwithstanding anything in this TSA to the
        contrary, no payment due hereunder is subject to reduction, set-off or
        adjustment of any nature by Customer, except as is specifically provided
        in Section 5 of the Service and Pricing Exhibit regarding Outage
        Credits. In no event shall the malfunction or non-operation of
        Customer's Interconnection Facilities (including local access when
        Customer is responsible therefor) relieve Customer of its obligation to
        pay for the Facilities.

5.5     All disputes or requests for billing adjustments must be submitted in

        writing and submitted with payment of undisputed amounts due. Any
        amounts which are determined by Qwest to be in error or not in
        compliance with this TSA shall be adjusted on the next month's invoice.
        Any disputed amounts which are deemed by the parties to be correct as
        billed and in compliance with this TSA, shall be due and payable by
        Customer, upon notification and demand by Qwest, along with any late
        payment charges which Qwest may impose pursuant to Section 5.3 above.
        Disputed amounts unresolved by the parties within [*] of written
        submission by Customer may be submitted to binding arbitration in
        accordance with the terms of Article 16 below. Disputes shall not be
        cause for Customer to delay payment of the undisputed balance to Qwest
        according to the terms outlined in Section 5.3 above.

5.6     Invoices submitted to Customer by Qwest shall conform to Qwest's
        standard billing format and content, as modified by Qwest from time to
        time.

5.7     Any applicable federal, state, or local taxes, and all use, sales,
        commercial, gross receipts, privilege or other similar taxes or license
        fees, whether charged to or against Qwest or Customer, with respect to
        the Services or Facilities provided by Qwest, as well as any other
        imposition by any governmental authority which has the effect of
        increasing Qwest's

        payment was due or as allowed for in Section 5.5 herein; (b) either
        party fails to perform or observe any material term or obligation (other
        than making payment) contained in this TSA, and any such failure remains
        uncorrected for thirty (30) calendar days after written notice from the
        non-defaulting party informing the defaulting party of such failure
        (except for a Default by Customer under Section 9.2 of this TSA, which
        shall require no advance written notice); (c) Customer breaches its
        obligations to Qwest in any other agreement, including but not limited
        to, agreements for switched services or any collocation agreements; or
        (d) there is an Adverse Material Change (as defined in Section 6.2 of
        this TSA) in Customer's creditworthiness.

6.2     For purposes of Section 6.1 of this TSA, an Adverse Material Change in
        Customer's creditworthiness shall include, but not be limited to: (a)
        failure of Customer to make full payment of charges due hereunder on or
        before the date due on three (3) or more occasions during any period of
        twelve (12) months, or Customer's failure to make such payment on or
        before the date due in any two (2) consecutive months; (b) acquisition
        of Customer (whether in whole or by majority or controlling interest) by
        an entity which is insolvent, which is subject to bankruptcy or
        insolvency proceedings, which owes past due amounts to Qwest or any
        entity affiliated with Qwest, or which presents a materially greater
        credit risk than Customer; or (c) Customer's being subject to or having
        filed for bankruptcy or insolvency proceedings, or the legal insolvency
        of Customer.

6.3     Notwithstanding Section 6.1 of this TSA, the failure of any particular
        Facility or reasonable number of Facilities to comply with the
        Specifications (as that term is defined in Section 2.1 of Exhibit A)
        shall not be deemed a Default by Qwest, but may obligate Qwest to
        provide Customer with Outage Credits, as provided in Section 5 of
        Exhibit A.

        it has under this TSA or under the law: (a) suspend its performance

        Customer, until Customer has remedied all breaches of this TSA and paid
        in full all charges then due, including any late fees specified herein

        applied to Services Ordered), as is specified in Section 5.3 of this
        TSA; (b) condition provision of Services or Facilities or acceptance of
        a Service Order on Customer's assurance of payment and compliance with

        or (c) terminate this TSA by providing written notice to Customer in the
        manner provided in Section 8.2 of this TSA.

        failure of performance, in the manner and subject to Section 10.2 of
        this TSA or Section 1.3 of Exhibit A.

8.4     Subject to Section 3 of Exhibit D, in the event of a termination of this
        TSA by either Customer or Qwest for reasons other than due to a Customer
        Default, all existing services being provided shall continue without
        interruption for the time period specified in the applicable Service
        Order, but no additional Service Orders shall be submitted or accepted.
        For services which continue after a termination of the TSA, pricing
        shall be at the rates specified in this TSA and the applicable Service
        Order unless the termination is pursuant to subparagraphs 8.2(a) or
        8.2(c)(ii), in which case the pricing shall revert to retail or standard
        discount pricing.

9.      GOVERNMENTAL AUTHORITY:

9.1     Customer acknowledges that the obligation of Qwest to provide the
        Facilities to Customer is subject to the receipt by Qwest of any
        required regulatory or other governmental authorizations. This TSA may
        be superseded by a tariff filed with the appropriate regulatory agency,
        which tariff may contain such modifications of the provisions of this
        TSA as Qwest deems appropriate, all of which shall become automatically
        binding on Customer. Qwest reserves the right to terminate this TSA
        pursuant to Section 8.2 of this TSA if at any time Qwest does not have
        or loses the required regulatory or other governmental authorizations to
        provide the Services or Facilities.

9.2     Customer represents and warrants that: (A) Customer has received all
        necessary permits, licenses, approvals, grants, and charters of
        whatsoever kind necessary to carry out the business in which Customer is
        engaged; and (B) Customer has complied and does comply with all laws,
        regulations, orders, and statutes which may be applicable to Customer,
        whether local, State or Federal. From the date of this TSA until the
        termination hereof, Customer agrees to operate in accordance with and to
        maintain current all such certifications, permits, licenses, approvals,
        grants, charters, and to comply with all applicable laws, regulations,
        orders and statutes, whether local, State or Federal. A breach by
        Customer of any of the representations, warranties or covenants of this
        Section 9.2 shall be deemed a Default hereunder, and shall allow Qwest
        to terminate this TSA in the manner described in Section 8.2 of this
        TSA.

10.     FORCE MAJEURE:

10.1    Except as is provided in Section 10.2 below, neither party to this TSA
        shall be liable for any failure of performance hereunder due to causes
        beyond its reasonable control, including, but not limited to: acts of
        God, fire, explosion, vandalism, fiber optic cable cut, storm, extreme
        temperatures or other similar catastrophes; any law, order, regulation,
        direction, action or request of the United States government, or of any
        other government,

        including state and local governments having jurisdiction over either of
        the parties, or of any department, agency, commission, court, bureau,
        corporation or other instrumentality of any one or more said
        governments, or of any civil or military authority; national
        emergencies, insurrections, riots, wars, or strikes, lock-outs, work
        stoppages or other labor difficulties; actions or inactions of a third
        party provider or operator of facilities employed in provision of the
        Services or Facilities; or any other conditions or circumstances beyond
        the reasonable control of the party which impede or affect the Services
        or Facilities or the transmission of telecommunications services.

10.2    If any failure of performance on the part of Qwest described in Section
        10.1 of this TSA related to a Service Order for a private line Facility
        shall be: (a) for thirty (30) calendar days or less, then this TSA shall
        remain in effect, but Customer shall be relieved of its obligation to
        pay for that portion of the Facilities affected for the period of such
        failure of performance; or (b) for more than thirty (30) days, then
        Customer may terminate only that portion of any Service Order or Service
        Orders related to the Facilities so affected, by written notice to
        Qwest, in accordance with Section 8.3 of this TSA.

        any events described in Section 10.1, Customer may be entitled to an
        Outage Credit under Section 5 of Exhibit A.

11.     INDEMNIFICATION:

11.1    Customer shall indemnify and hold harmless Qwest (and Qwest's
        affiliates, officers, directors and employees; hereafter, "Qwest's
        Affiliates"), and any third party provider or operator of services
        employed by Qwest and/or Qwest's Affiliates in the provision of the
        Services or Facilities, from and against, and shall reimburse Qwest
        and/or Qwest's Affiliates for, any and all losses, liabilities,
        deficiencies, claims and expenses (including, but not limited to, costs
        of defense and reasonable attorneys' fees) incurred by Qwest and/or
        Qwest's Affiliates and arising from or in connection with: (a) any
        breach of any covenant or agreement of Customer contained in this TSA;
        (b) any misrepresentation or breach of any of the representations and
        warranties of Customer contained in this TSA; or (c) any claims which
        may be asserted by parties other than Customer who have use of or access
        to the Services or Facilities through Customer.

11.2    Customer shall indemnify and hold harmless Qwest and Qwest's Affiliates
        and any third party provider or operator of facilities employed by Qwest
        and/or Qwest's Affiliates in the provision of the Services) from and
        against, and shall reimburse Qwest and/or Qwest's Affiliates for, any
        and all losses, liabilities, deficiencies, claims and expenses
        (including, but not limited to, costs of defense and reasonable
        attorneys' fees) incurred by Qwest, arising from unauthorized calls of
        any nature which may comprise a portion of the Services, to the extent
        that the call(s) in question are or were unauthorized (or had been at
        the time of the call) by an end user of the Services through Customer's
        distribution channels.

        Customer shall not be excused from paying Qwest for Services provided to
        Customer or any portion thereof on the basis that unauthorized calls
        comprised a corresponding portion of the Services. If Qwest discovers
        unauthorized calls being made (or reasonably believes that unauthorized
        calls are being made), nothing contained herein shall prohibit Qwest
        from taking immediate action (without notice to Customer) that is
        reasonably necessary to prevent such unauthorized calls from being made,
        including without limitation, denying Services to particular ANIs or
        terminating Services to or from specific locations.

11.3    Qwest shall indemnify and hold harmless Customer (and Customer's
        affiliates, officers, directors and employees; hereafter, "Customer's
        Affiliates"), and any third party provider or operator of services used
        by Qwest in the provision of the Services or Facilities, from and
        against any and all losses, liabilities, deficiencies, claims and
        expenses (including, but not limited to, costs of defense and reasonable
        attorney's fees) incurred by Customer and/or Customer's Affiliates and
        arising from or in connection with: (a) any breach of any covenant or
        agreement of Qwest contained in this TSA; (b) any misrepresentation or
        breach of any of the representations and warranties of Qwest contained
        in this TSA; or (c) the gross negligence or willful misconduct of Qwest.

12.     ASSIGNMENT:

12.1    Neither party may transfer, assign, or otherwise in any manner encumber
        this Agreement and its rights and obligations hereunder without the
        prior written consent of the other party, which consent shall not be
        unreasonable withheld.

12.2    Notwithstanding the provisions of Section 12.1 to the contrary, either
        party may assign this Agreement to any parent, subsidiary or affiliate
        of the other party, including any transfers incident to an acquisition
        or change of control of either party, provided, however, that in the
        case of Customer: (i) such transfer or assignment does not cause an
        Adverse Material Change in Customer's creditworthiness as described in
        Section 6.2 herein; or (ii) Customer fails to comply with the provisions
        of Section 9 herein as a result of such transfer or assignment
        ("Permitted Assignment"). In the event that Customer makes a Permitted
        Assignment during the Term of this Agreement, Qwest may, in its sole
        discretion, terminate this Agreement and Customer shall not be
        responsible for any Termination Charge (as defined in Section 3 of
        Exhibit D). For purposes of this Section 12.2, "subsidiary or affiliate"
        shall mean any entity that is controlled directly or indirectly by
        either party through the ownership or control of more than 50% of the
        equity interests in such entity.

        INCORRECT OR DEFECTIVE TRANSMISSIONS, OR ANY DIRECT OR INDIRECT
        CONSEQUENCES THEREOF.

14.4    EXCEPT FOR QWEST'S GROSS NEGLIGENCE OR WILFUL MISCONDUCT,

        enforcing a judgment of the arbitrators separately from and in addition
        to any other amount included in such judgment. This Section 16.3 shall

        create a partnership or joint venture between the parties or result in a

18.3    The failure of either party to give notice of default or to enforce or
        insist upon compliance with any of the terms or conditions of this TSA
        shall not constitute a waiver of any term or condition of this TSA.

18.4    Subject to Section 16 of this TSA, in the event suit is brought or an
        attorney is retained by either party to enforce the terms of this TSA or
        to collect any moneys due hereunder or to collect money damages for
        breach hereof, the prevailing party shall be entitled to recover, in
        addition to any other remedy, reimbursement for reasonable attorneys'
        fees, court costs, costs of investigation and other related expenses

        party.

18.7    If any part of any provision of this TSA shall be invalid or
        unenforceable under applicable law, said part shall be ineffective to
        the extent of such invalidity only, without in any way affecting the
        remaining parts of said provision or the remaining provisions of this
        TSA, and Customer and Qwest agrees to negotiate with respect to any such
        invalid or unenforceable part to the extent necessary to render such

                      TELECOMMUNICATIONS SERVICES AGREEMENT

                    PRIVATE LINE SERVICE AND PRICING EXHIBIT


1.      QWEST SERVICES:

1.1     Telecommunications capacity and related ancillary services (the
        "Facility" or "Facilities") available from Qwest are identified in this
        Exhibit A. During the Term of the TSA, Qwest will provide to Customer
        the Facility or Facilities requested by Customer in a Service Order
        accepted by Qwest.

1.2     Upon acceptance of a Service Order, Qwest shall notify Customer of its
        target date for the delivery of each Facility (the "Estimated
        Availability Date"). Any Estimated Availability Date given by Qwest to
        Customer shall be subject to Qwest's standard and expedited interval
        guidelines, as amended by Qwest from time to time. Qwest shall use
        reasonable efforts to install each such Facility on or before the
        Estimated Availability Date, but the inability of Qwest to deliver a
        Facility by such date shall not be a Default under the TSA. If Qwest
        fails to make any Facility available within ninety (90) days after
        acceptance (120 days for OC-3 or above) by Qwest of the Service Order
        with respect to such Facility (or such greater time as is set forth in
        the interval guidelines), Customer's sole remedy shall be to cancel the
        Service Order which pertains to such Facility by ten (10) calendar days
        prior written notice to Qwest, as is set forth in Section 8.3 of the TSA
        and the amounts applicable to such cancelled Service Order shall count
        toward the Minimum Revenue Commitment in the applicable Commitment
        Period as provided in Exhibit D.

1.3     Customer acknowledges that Qwest has no ability to independently test or
        maintain Facilities between two off net cities. Consequently, if Qwest
        provides such Facilities, then notwithstanding anything in this TSA to
        the contrary, Qwest's entire duty with respect to such Facilities shall
        be to use its best efforts to test and maintain such Facilities in
        accordance with Qwest's Specifications.

1.4     At each end of the city pairs (the "City Pairs") on which Customer
        orders Facilities, Qwest shall provide appropriate equipment in its
        terminal locations necessary to connect the Facilities to Customer's
        Interconnection Facilities (as defined in Section 1.5 of this Exhibit
        A). If Customer desires to install its own equipment in one or more of
        Qwest's terminals,



                              Qwest Communications
                          Confidential and Proprietary

                                        1
<PAGE>   18

        and Qwest, in its sole discretion, agrees to such installation, the
        parties shall execute a Qwest Collocation License Agreement.

1.5     Customer agrees that Customer's Interconnection Facilities shall connect
        to the Facilities provided by Qwest hereunder at the network interface
        points located in the Qwest terminals and defined in the Specifications
        (as defined in Section 2.1 of this Exhibit A). As used herein, the term
        "Interconnection Facilities" shall mean transmission capacity provided
        by Customer or its third party supplier to extend the Facilities
        provided by Qwest from a Qwest terminal to any other location (e.g., a
        local access telephone service provided by a local telephone company).

1.6     For DS-3 Facilities and below, Qwest shall use reasonable efforts to
        order Interconnection Facilities on behalf of Customer from Customer's
        designated supplier, provided that Customer furnishes Qwest with an
        acceptable letter of agency. Customer shall be billed directly by the
        supplier of such Interconnection Facilities, and shall hold harmless and
        indemnify Qwest from any loss or liability incurred by Qwest as a result
        of Qwest's ordering Interconnection Facilities from any third party.
        Customer may, at its election, but subject to Qwest's prior written
        approval, order its own Interconnection Facilities. If any party other
        than Qwest provides Interconnection Facilities, then unavailability,
        incompatibility, delay in installation, or other impairment of
        Interconnection Facilities shall not excuse Customer's obligation to pay
        Qwest all Rates or charges applicable to the Facilities, whether or not
        such Facilities are useable by Customer. Qwest will not order
        Interconnection Facilities on behalf of Customer for OC-n Facilities.

2.      START OF SERVICES:

2.1     Start of service for each Facility (the "Start of Service Date") shall
        begin on the date on which Customer accepts delivery of such Facility.
        If Customer fails to give written notice that the Facility is in
        material non-compliance with the applicable standard Qwest network
        specifications, as modified from time to time by Qwest (the
        "Specifications") within five (5) business days after notification to
        Customer by Qwest that the Facility is available, Customer shall be
        deemed to have accepted such Facility, and the Start of Service Date
        shall commence as of the fifth day following such notification by Qwest.
        Following notice by Customer of material non-compliance as set forth
        above, Qwest shall promptly take such reasonable action as is necessary
        to correct any such non-compliance in the Facility and shall, upon
        correction, notify Customer of a new Start of Service Date.

2.2     Notwithstanding anything in Section 2.1 of this Exhibit A to the
        contrary, Customer may delay the Start of Service Date for any Facility
        for up to thirty (30) days from Qwest's

        in this Section 3 (exclusive of all sales, use, commercial or other
        taxes or license fees) and as shown on the Circuit Listing attached as
        Schedule A-1 to this Exhibit A. The Rates for each Facility also include
        certain Monthly Recurring and Non-Recurring charges, all as defined in

3.2     Qwest reserves the right, upon thirty (30) days prior written notice to
        Customer, to modify any of the Rates or charges described in this
        Exhibit A applicable to any Facility or Facilities. Upon receipt of
        written notice of such election, Customer may terminate the TSA, as per
        Section 8.1 thereof, or terminate the portion of the Service Order or
        Service Orders which pertain to such Facility or Facilities by
        delivering written notice of termination to Qwest within thirty (30)
        days of the date of the written notice of increase. If written notice of
        termination from Customer is not received within such thirty (30) day
        period, Customer will be deemed to have consented to the increase.

4.      FACILITY MINIMUM SERVICE TERM:

4.1     Customer acknowledges that the Rates and charges described in Section 3
        of this Exhibit A are based on the commitment of Customer to utilize the
        Facilities for a specified minimum period of time. Therefore,
        notwithstanding anything in the TSA to the contrary, Customer shall be
        liable for and shall pay to Qwest all Rates, fees and charges which
        accrue under the TSA for each Facility for the entire Facility Minimum
        Service Term (as defined in Section 4.2 of this Exhibit A) applicable to
        each such Facility, regardless of

        whether or not Customer utilizes all or any part of such Facility during
        all or any part of the Facility Minimum Service Term applicable to such
        Facility, except as is set forth in Section 4.3 of this Exhibit A.

4.2     The "Facility Minimum Service Term" for each Facility is defined as
        follows:

        (a)     Six (6) months from Start of Service Date for DS-1 Facilities.

        (b)     Twelve (12) months from Start of Service Date for DS-3
                Facilities.

        (c)     Twelve (12) months from Start of Service Date for OC-3
                Facilities.

        (d)     Thirty-six (36) months from the Start of Service Date for OC-12
                or above Facilities.

4.3     Notwithstanding anything in this TSA to the contrary, Customer's
        obligation to pay all rates, fees and charges which accrue under this
        TSA for each Facility for the entire Facility Minimum Service Term
        applicable to each such Facility shall terminate, as to each such
        Facility, if this TSA is terminated during the Minimum Service Term
        which pertains to each such Facility: (a) by Customer, pursuant to
        Sections 8.1(a) or (b) of the TSA, following a Default by Qwest or an
        increase in prices; or (b) by Qwest, pursuant to Section 8.2(b) of the
        TSA, if termination by Qwest during the Minimum Service Term as to the
        Facility occurs other than because of a Default by Customer, or 8.2(c)
        of the TSA, if Qwest terminates this TSA because Qwest loses any
        required permits. Qwest recognizes that Customer's business needs may
        change during the Facility Minimum Service Term. Therefore, for any
        Facility ordered under this Agreement, Customer may, after the first six
        (6) months of such Facility Minimum Service Term, cancel said Facility,
        and order as a substitute an alternative Facility from Qwest on the
        Qwest owned fiber optic network. Any such Order must be: (a) for a like
        Facility Minimum Service Term (e.g., if original order was for one (1)
        year, new order must be for one (1) year; (b) will be filled at Qwest's
        discretion subject to network availability; and (c) for a Facility that
        has greater bandwidth than the originally ordered Facility (e.g., if
        original order specified a DS-3 Facility, any new order under this
        Section 4.4 must request an OC-3 Facility or above).

5.      OUTAGE CREDITS:

5.1     Customer acknowledges the possibility of an unscheduled, continuous
        and/or interrupted period of time when a Facility or Facilities are
        "unavailable" (as defined in the Specifications) (hereafter an
        "Outage"). In the event of an Outage, Customer shall be entitled to a
        credit (the "Outage Credit") determined according to the following
        formula:

                                      720 HOURS
</TABLE>

5.2     The Outage Credit shall apply to the charges for the total mileage
        between end terminals of any Facility affected by an Outage; provided,
        however, that if any portion of the affected Facility remains
        beneficially used or useable by Customer between any intermediate
        terminals (where Customer has installed drop and insert capability) or
        end terminals, the Outage Credit shall not apply to that pro-rata
        portion of the mileage. The length of each Outage shall be calculated in
        hours and shall include fractional portions thereof. An Outage shall be
        deemed to have commenced upon verifiable notification thereof by
        Customer to Qwest, or, when indicated by network control information
        actually known to Qwest network personnel, whichever is earlier. Each
        Outage shall be deemed to terminate upon restoration of the affected
        Facility as evidenced by appropriate network tests by Qwest. Qwest shall
        give notice to Customer of any scheduled outage as early as is
        practicable, and a scheduled outage shall under no circumstance be
        viewed as an Outage hereunder.

5.3     Outage Credits shall not be granted if the malfunction of any end-to-end
        circuit is due to an Outage or other Defect occurring in Customer's
        Interconnection Facilities.

5.4     All Outage Credits shall be credited on the next monthly invoice for the
        affected Facility after receipt of Customer's request for credit. The
        total of all Outage Credits applicable to or accruing in any given month
        shall not exceed the amount payable by Customer to Qwest for that same
        month for such Facility.

5.5     The Outage Credit described in this Section 5 of Exhibit A shall be the
        sole and exclusive remedy of Customer in the event of any Outage, and
        under no circumstance shall an outage be deemed a Default under this
        TSA.

2.      PERFORMANCE OBJECTIVES:

2.1     DS1, DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c circuit
        performance will be measured using two parameters: Availability and
        Error-Free Seconds.

        The following assumptions apply to the derived data:

                ~       The circuits originate and terminate on the SONET OC-48
                        backbone

                ~       High speed protection switching: 1 for N, where N=2

                ~       MTTR for SONET equipment: 2 hours

                ~       MTTR for fiber optic cable: 12 hours (Bellcore Standard)

                ~       Cable cut rate: 4.39 /year/1,000 sheath miles (Bellcore
                        Standard)
                                The system includes three (3) DCS in Los
                                Angeles, Sacramento, and San Jose (although not
                                all circuits are routed through the DCS, they
                                are included in all the calculations)

2.2     Availability is a measure of the relative amount of time during which
        the circuit is available for use. According to CCITT and ANSI
        definitions, unavailability begins when

        the Bit Error Ratio (BER) in each second is worse than 1.0 E-3 for a
        period of 10 consecutive seconds.

        INTER OFFICE CHANNEL (IOC): An Inter Office Channel refers to the Qwest
        Communications network between the points of presence (POP).

        OPTICAL CARRIER LEVEL 1 (OC-1): The optical signal that results from an
        optical conversion of an electrical STS-1 signal (51.840 Mb/s). This
        signal forms the basis of the interface.

                OC-3:   Optical Carrier level 3 signal operating at 155.520
                        Mb/s.

                OC-12:  Optical Carrier level 12 signal transmitting at 622.080
                        Mb/s.

                OC-48:  Optical Carrier level 48 signal transmitting at 2488.32
                        Mb/s.

        POINT OF PRESENCE (POP): A physical location where a long distance
        carrier terminates lines before connecting to the local exchange
        carrier, another carrier, or directly to a customer.

2.3     The availability objective for all circuits between Qwest Network
        Interface points specified above is to provide performance levels over a
        12 month period as follows:

               2501-4000                    99.998%
</TABLE>

        This excludes any customer provided access links to the Qwest digital
        network.

2.4     Outages attributable to incidental damage to or severage of outside
        fiber optic cable plant, or scheduled maintenance is excluded from the
        performance objective stated above.

2.5     Error-Free Seconds (EFS) and Error Seconds (ES) are the primary measure
        of error performance. An Error-Free Second is defined as any second in
        which no bit errors are received. Conversely, an Error Second is any
        second in which one or more bit errors are received.

3.      SONET: Synchronous Optical Network is a family of optical transmission
        rates and interface standards allowing internetworking of products from
        different vendors. Base optical rate is 51.840 Mb/s. Higher rates are
        direct multiples.

        SONET TRANSPORT: Facilities associated with carrying OC-1 or higher
        level signals.

        SYNCHRONOUS TRANSPORT SIGNAL LEVEL 1 (STS-1): The basic logical building
        block electrical signal with a rate of 51.840 Mb/s.

        SYNCHRONOUS TRANSPORT SIGNAL LEVEL N (STS-N): This electrical signal is
        obtained by byte interleaving N STS-1 signals together. The rate of the
        STS-N is N times 51.840 Mb/s.

        TERMINATING MULTIPLEX (TM): Provides the multiplex functions for
        multiplexing and demultiplexing between the DS1 or higher signal level
        and the SONET OC-N level.

4.      ACCEPTANCE CRITERIA. The acceptance criteria for DS1, DS3, OC-3, OC-12,
        OC-48, OC-3c, OC-12c, and OC-48c circuits between Qwest Network
        Interface points is to provide the performance levels shown below during
        a 60 minute test period. If no errors are observed during the first 15
        minutes of the test, the facility may be considered acceptable. Access
        connections to customer location will be tested in accordance with Bell
        Publication 62508.

           ~   The tables below are based on QCC owned fiber optic network only
               and on the Bellcore Specifications of the SONET delivery of DS1,
               DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c directly off
               the SONET Backbone.

           ~   If the DS1, DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c
               service is delivered at the STS1 level then the general
               performance objectives fall into the industry standard.

        DS1, DS3

        The table below defines the general performance objectives for DS1
        service operating at 1.544 Mb/s, and the general performance objectives

                  SWITCHED SERVICES SERVICE AND PRICING EXHIBIT



1.      QWEST SERVICES:

1.1     Qwest shall provide to Customer Switched Services ("Services" or
        "Switched Services"), subject to the terms and conditions of the TSA.
        During the Term of the TSA, Qwest will provide to Customer the Services
        requested by Customer in a Service Order accepted by Qwest.

2.      START OF SERVICES:

2.1     Services shall commence ("Start of Services") pursuant to each Service
        Order, with the activation of each circuit comprising Service
        Interconnections (as defined in Section 4.1 of this Exhibit B).

3.      FORECASTS:

3.1     Before Customer's initial order for Service, Customer shall provide
        Qwest with a forecast regarding the number of minutes expected to be
        terminated or originated in various LATAs and/or Tandems, so as to
        enable Qwest to configure optimum network arrangements. In the event
        Customer's service traffic volumes result in a lower than industry
        standard completion rate or otherwise adversely affect the Qwest
        Network, Qwest reserves the right to block the source of such adverse
        traffic upon written notice to Customer. Customer will provide Qwest
        with additional forecasts from time to time upon Qwest's request which
        shall not be more frequent than once every three (3) months.

4.      SERVICE INTERCONNECTIONS:

4.1     Customer shall establish dedicated T-1 access and interexchange
        facilities connections ("Service Interconnection(s)") between Customer's
        network and switching system under Customer's direct control or
        ownership and the Qwest network at one or more of Qwest's Points of
        Presence ("Qwest POP"). Qwest POP's are currently located in the cities
        identified on Schedule "B-5" attached hereto as the "Meet Point Cities".

                          Confidential and Proprietary

                                        1
<PAGE>   30

4.2     Customer shall deliver, or receive, its traffic at a Qwest POP via the
        Service Interconnections, as described in Section 4.1 of this Exhibit B
        or as specified in Section 4 of Exhibit D to the TSA. If, for any
        reason, Customer is unable or fails to deliver its traffic to a Qwest
        POP in a Meet Point City in accordance with Section 4.1 of this Exhibit
        B, Qwest may, at its option, establish a Service Interconnection for
        such traffic ("Backhaul Services") for and on behalf of Customer to the
        nearest Qwest POP having available capacity as determined by Qwest. In
        such event, Customer shall pay to Qwest charges for Backhaul Services at
        Qwest's then current rates, which shall be based on a per DS-0 V&H
        mileage charge.

4.3     Prior to Qwest's acceptance of a Service Order which requests Services
        through any Meet Point Cities, Qwest reserves the right to add or remove
        Meet Point Cities to or from the list attached at Schedule B-7, and
        shall endeavor to provide Customer with reasonable advance notice of any
        additions or removals.

4.4     In addition to the foregoing amounts, within thirty (30) days of the
        Service Date, Customer shall pay to Qwest a non-recurring charge of [*]
        for each Service Interconnection installed at each service location,
        except that if more than one Service Interconnection is installed at a
        single service location simultaneously, Customer shall pay to Qwest [*]
        for each additional Service Interconnection beyond the first Service
        Interconnection installed at each such location. The Non-Recurring
        charges will be waived for all individual circuit orders of thirty-six
        (36) months or greater term.

5.      CALL DETAIL RECORDS:

5.1     Upon request from Customer, Qwest shall provide Call Detail Records
        ("CDR's") for the Services on compact disc(s) ("CDR Compact Disc(s)").
        Qwest shall provide to Customer one (1) CDR per month. Monthly CDR
        Compact Discs under this Subsection are provided at a recurring charge
        of [*] per month for the first disc, and [*] for each additional disc.

6.      MINIMUM USAGE AND TERMINATION FEE:

6.1     Customer hereby agrees that, commencing with the first day of the fourth
        full calendar month after the Start of Services, and ending upon
        termination of the TSA, Customer shall maintain an average loading of
        traffic of not less than [*] minutes of use per Service Interconnection
        per calendar month/billing cycle, averaged over all Service
        Interconnections in each Customer trunk group ("Minimum Usage
        Requirement"). If Customer fails to meet the Minimum Usage Requirement
        in any calendar month/billing

        cycle, Customer expressly authorizes Qwest to add a surcharge to the
        next subsequent invoice of [*] of use per Service Interconnection for
        each minute of under-utilization for such calendar month/billing cycle.

7.      ROUNDING

7.1     Currently, Qwest Switched Services, Termination, 8XX Origination, and
        Switchless Resale, utilize "bulk rounding". For the purposes of this
        agreement, bulk rounding is defined as carrying over the 3rd and 4th
        place amounts of a call charge to the next call, and continuing to do so
        until one full cent ($.01) is accrued. When this has occurred, the cent
        is applied to the next call. In addition, Qwest Switched Services employ
        [*], which means that all calls are [*], as opposed to [*] (e.g. initial
        and incremental).

8.      PRICING/RATES

8.1     Qwest's charges for terminating switched calls under the TSA shall be as
        specified in the attached Schedules B-1 and B-2. Qwest's charges for
        originating calls under the TSA shall be as specified in the attached
        Schedule B-3. Qwest's charges for switchless reseller services shall be
        as specified in the attached Schedule B-4.

9.      SERVICE/PRICE MODIFICATIONS

9.1     Qwest reserves the right, at any time during the Term of this TSA, upon
        thirty (30) days prior written notice to Customer, to modify domestic
        rates. Upon receipt of written notice of such election, Customer may
        terminate the TSA, as per Section 8.1 thereof, or terminate the portion
        of the Service Order or Service Orders which pertain to such Facility or
        Facilities by delivering written notice of termination to Qwest within
        thirty (30) days of the date of the written notice of increase. If
        Customer's written notification is not received within ten (10) days of
        the effective date of the price increase, Customer shall be deemed to
        have consented to such price increase. Qwest also reserves the right, at
        any time during the Term of this TSA, upon fifteen (15) days prior
        written notice to Customer, to modify international rates and any other
        prices described in this Exhibit B. Upon receipt of written notice of
        such an election and in the event of a material rate increase (10%
        increase) by Qwest which materially affects Customer's actual usage
        hereunder, Customer shall receive a pro rata reduction in its Total
        Minimum Commitment (as defined in Exhibit D); provided, however,
        Customer must notify Qwest in writing setting forth in reasonable detail
        its basis for determining the materiality of the increase and the
        affects on actual usage. If Customer's written notification is not
        received within ten (10) days of the effective date of the price
        increase, Customer shall be deemed

        to have consented to such price increase. For purposes of determining
        any pro rata reduction in the Total Minimum Commitment, Qwest shall use
        as a basis Customer's usage for the applicable rate element and average
        the immediately preceding three months. By way of example, if Customer's
        average for the immediate preceding 3 months is $1000 and Customer has
        twelve (12) months left on the Initial Term, in the event of an
        applicable rate increase Qwest would reduce the Total Minimum Revenue
        Commitment 12 months times $1000 (equaling $12,000 for an overall
        reduction).

10.     GOVERNMENTAL AUTHORITY:

10.1    In the absence of Automatic Number Identification ("ANI") of the calling
        party, Qwest shall use the area code and prefix of the originating trunk
        group to determine whether a call is interstate or intrastate, and to
        calculate the corresponding charges for that call. Qwest may, from time
        to time, request that Customer provide Qwest with a written
        certification (the "Certification") of the percentage of interstate
        calls, including international and intrastate minutes of use, compared
        to the minutes of traffic to be terminated in the same state, in form
        and substance reasonably satisfactory to Qwest.

                               SERVICE DESCRIPTION
               QWEST EXPRESS RBOC/ITC TERMINATING SWITCHED SERVICE

1.      GENERAL

1.1     Interstate rates are per Local Access and Transport Area ("LATA") and
        are for LATA-wide termination. Regional Bell Operating Company ("RBOC")
        rates apply to all traffic terminating in RBOC territories, and
        independent telephone company ("ITC") rates, or Non-Bell rates, apply to
        all traffic terminating in ITC ("Non-RBOC") territories. For the
        purposes of billing the appropriate territory, the OCN number of the
        terminating carrier will be used. OCN numbers of 9000 and above shall be
        classified as RBOC; and OCN numbers less than 9000 shall be classified
        as "ITC", or Non-RBOC.

1.2     Intrastate rates are per State and are for State-wide termination. For
        the purposes of determining each call's jurisdiction, the originating
        and terminating information present in the call stream will be
        evaluated. In the event that either the originating or terminating
        information is not available to Qwest's billing system, the
        classification of the call, for rating purposes, will default to the
        Interstate classification. To the extent that calls are defaulted to the
        Interstate classification, and to the extent Customer's traffic of this
        nature includes intrastate traffic, Customer shall provide to Qwest in
        writing, on a monthly basis, the "Percentage of Inter/Intra-state Usage"
        on a state-by-state basis, by LEC, for the traffic terminated by Qwest
        hereunder.

1.3     Rates shown in the Qwest Express RBOC/ITC Interstate and Intrastate Rate
        Exhibits are shown in terms of full minutes and are billed in [*]
        increments. Qwest reserves the right to charge excessive quantities of
        short duration calls (i.e. calls under [*] in length) a minimum of [*]
        per answered call. Rates shown in the Qwest Express RBOC/ITC Interstate
        and Intrastate Rate Exhibits are Base Rates. Discounts, if any, will be
        applied as specified in Schedule B-8 to this Exhibit B.

                                  SCHEDULE B-3
                               SERVICE DESCRIPTION
                       QWEST EXPRESS 8XX TRANSPORT SERVICE

1.      GENERAL

1.1     Interstate rates are per Local Access and Transport Area (LATA) and are
        for LATA-wide origination. Rates shown in the attached Rate Exhibit are
        shown in terms of full minutes and are billed in six (6) second
        increments. All calls will be billed a minimum of $.01.

2.      CUSTOMER AS RESPONSIBLE ORGANIZATION ("RESP ORG")

2.1     Customer agrees to be responsible for or act as RESP ORG, to manage and
        administer their records in the 8XX Service Management System.
        Customer's responsibilities shall be limited to coordinating data entry,
        record change, trouble acceptance, referral and/or clearance. As RESP
        ORG, Customer will also provide coordination to provision, maintain, and
        test 8XX Data Base ("DB") service between various entities, such as:
        Local Exchange Carriers ("LECs"), Interexchange Carriers ("IXCs"),
        Number Administration and Service Center ("NASC"), and the Service
        Management System ("SMS").

3.      RBOC-ITC" SURCHARGE

3.1     Customer will maintain at least 80% of the traffic comprising Customer's
        800 Origination Service for origination in a Tandem owned and operated
        by a Regional Bell Operating Company (RBOC) and subject to such RBOC's
        tariffed access charges. Qwest will have the right to apply a [*] per
        minute of use surcharge to the number of minutes by which Non-RBOC
        Originating minutes exceed 20% of total monthly Origination service
        minutes. Qwest will not consider traffic originating in Customer areas
        where Customer is providing local access service in the Non-Bell usage
        surcharge calculation, provided, Customer is equal to or below LEC
        access tariff pricing in such Customer areas. For the purposes of
        automating the billing of the surcharge, the OCN number of the
        originating carrier will be used. OCN numbers of 9000 and above are
        classified as RBOC; and OCN numbers less than 9000 are classified as
        "ITC", or Non-RBOC.

5.      INDEMNIFICATION

        claims for libel, slander, invasion of privacy or infringement of
        copyright arising from Customer's or its 800 subscriber's own
        communications, except to the extent such claim, loss or damage is
        caused by Qwest's willful misconduct or gross negligence.

        transport responsibility.

7.5     Customer shall cause the RESP ORG to notify Qwest of the assignment of
        the applicable record and Customer shall ensure such record is not

7.6     Customer shall be ready to accept traffic prior to submitting to Qwest
        an order to turn up 800 Service.

7.7     Customer shall be responsible for all costs in connection with updating

8.      CUSTOMER OBLIGATIONS FOR USE OF ALTERNATE CIC MAP

8.1     Customer shall ensure that no CICs other than Customer's will be used in
        conjunction with Qwest's CIC without ten (10) days prior written
        notification to Qwest. Qwest reserves the right to not approve of a
        change to a CIC other than Customer's or Qwest's. Customer understands
        that it will be responsible for all usage associated with traffic
        related to an 8XX number that Qwest refused to approve for a CIC change
        if the call is carried on Qwest's network.

8.2     Customer shall not enter into any arrangement with a third party for the
        provision or carriage of any component of any 800 traffic transported by
        Qwest.

8.3     Customer shall promptly and accurately perform all Qwest requested
        changes to its CIC map. Customer shall be responsible for all costs
        resulting from its failure to comply with this provision.

8.4     Qwest provides CIC mapping at the LATA level only.

8.5     Where Customer chooses to select itself for 800 origination in a
        particular LATA, Customer must provide complete LATA coverage.


8.6     ALL TOLL-FREE CALLS ORIGINATING FROM A PAY-PHONE WILL INCUR A PER-CALL
        SURCHARGE OF [*] AS DEFINED IN SECTION 9.2 OF SCHEDULE B-3. SUCH CHARGES
        WILL NOT RECEIVE THE VOLUME DISCOUNTS LISTED IN SCHEDULE B-8.

                             QWEST SWITCHLESS RESALE


1.      SCOPE OF AGREEMENT

1.1     Qwest will provide to Customer and Customer will purchase from Qwest
        certain Qwest domestic and international long distance services
        described in the Exhibits hereto ("Switchless Reseller Service(s)")
        provided pursuant to Qwest/LCI Tariff F.C.C. No. 1, Qwest/LCI Tariff
        F.C.C. No. 2, and applicable state tariffs (collectively, "Tariff(s)"),
        which are on file with the Federal Communications Commission ("FCC") and
        applicable state regulatory bodies. The Tariffs may be modified from
        time to time by Qwest in accordance with law and thereby affect the
        Service(s) furnished Customer. To the extent applicable to the
        furnishing of Qwest Services hereunder, the Tariff, as amended from time
        to time, is hereby incorporated herein and made a part hereof, except
        that the following terms and conditions shall supplement or, to the
        extent inconsistent, supersede Tariff terms and conditions and shall
        remain in effect throughout the service term, as hereinafter defined.

1.2     Customer shall pay all applicable federal, state and local taxes and
        surcharges unless and until Customer submits valid tax exemption
        certificates for an applicable tax. Credits or refunds of tax payments
        will not be issued to Customer for usage prior to the submission of tax
        exemption certificates.

2.      CUSTOMER SERVICE AND BILLING

2.1     Customer acknowledges and agrees that it shall provide all billing,
        inquiry, and customer service to End-Users. Qwest shall only be
        obligated to provide customer service to Customer.

2.2     Customer acknowledges that it may not withhold any sums invoiced by
        Qwest for actual calls made by Customer including, without limitation,
        calls made by Customer's End Users and/or unauthorized third parties
        (e.g., fraudulent calls) and charges to Customer's Qwest account(s).

3.      PIC AUTHORIZATIONS

        Customer shall obtain a signed or verbal interexchange carrier ("PIC")
        authorization with true third party verification and archived recordings
        according to state or FCC guidelines for each ANI ordered by Customer.
        Upon an oral or written request by Qwest, Customer shall immediately
        produce a copy of the written or verbal authorization. Qwest reserves
        the right not to process or turn up ANIs until Customer has produced
        appropriate written or verbal authorizations requested by Qwest. If
        Customer does not comply with the request for PIC authorizations, Qwest
        reserves the right not to accept additional ANIs until Customer
        complies.

3.1     If Customer elects to provide only direct dial (or so-called "1+")
        services, and Qwest will act as the interexchange carrier ("IXC") for
        operator-assisted (or so-called "0+") traffic generated by Customer's
        end users, Customer agrees where appropriate to inform its end-users
        that it:

        ~       designates Qwest as its primary carrier for 0+ operator assisted
                intraLATA long distance services;"

        ~       designates Qwest as its primary carrier for 0+ operator assisted
                interLATA long distance services;" or

        ~       designates Qwest as its primary carrier for 0+ operator assisted
                intraLATA and interLATA long distance services."

3.2     In the event a LEC or any regulatory entity assesses Qwest any charge,
        fine, forfeiture, or fee for improper or inadequate PIC authorizations
        relating to Customer's service, Customer shall promptly reimburse Qwest
        for all such charges plus an Qwest management fee of [*] per ANI ordered
        by Customer that is deemed to lack proper service authorization or PIC
        verification.

3.3     Upon the request of Qwest, Customer shall promptly provide to Qwest or
        the LEC, at Customer's expense, any documentation required by the LEC
        regarding PIC selections or authorizations from Customer's End Users. In
        addition, Customer shall promptly and in good faith cooperate with Qwest
        and all LECs in investigating and attempting to resolve all PIC
        selection and authorization disputes.

        manner set forth herein, is subject to the Communications Act of 1934,
        as amended, and as interpreted and applied by the Federal Communications
        Commission. All terms of this TSA not subject to the Communications Act
        of 1934 as amended and as interpreted and applied by the Federal
        Communications Commission will be interpreted according to New York law,
        without regard to its conflicts of law provisions. Any cause of action

        subjects the Service to regulation by such state, then the terms and
        conditions of such Service and of terminating switched services provided
        under this TSA shall be subject to such regulations and to any amendment
        to this TSA relating thereto which is delivered by Qwest to Customer.

        of receipt of such amendment without further liability hereunder.

5.3     Customer certifies and warrants that it is in compliance with and will
        continue to be in compliance with all international, federal, state and

        Agreement. Customer is solely responsible for obtaining all licenses,
        approvals, and regulatory authority for its operation and the provision
        of services to its customers ("End Users"). Any breach of the

        this Agreement. If Customer does not comply with this Section, in
        addition to any remedies available to Qwest at law or in equity, Qwest,
        in its sole discretion, may elect to decline to accept additional orders
        under this Agreement or may immediately terminate this Agreement without
        further liability or obligation to Customer.

        below LEC access tariff pricing in such Customer areas.

                files

        ~       submitted to Qwest on a 3.5" diskette

        ~       leading and trailing noise must be removed

        ~       One (1) second of silence is required in front of the message

of the Initial Term, Customer shall pay Qwest a termination fee equal to the
lesser of (a) the remaining charges applicable through the end of the Initial
Term as scheduled, or (b) six months of monthly recurring charges as applicable
during the month previous to early termination by Customer.

3.02 In addition to the termination rights provided in Section 8, Qwest may
terminate this Q.i/commerce Agreement and cease provision of any Services upon
default of Customer. Default includes the failure to pay any amount when due
hereunder; the filing of a petition in bankruptcy by or against Customer or
Customer's inability to meet obligations when due; or failure of Customer to
cure any violation (other than failure to pay) of the provisions of this
Q.i/commerce Agreement within thirty (30) days notice thereof by Qwest.

3.03 In the event a law or regulatory action prohibits, substantially impairs or
makes impractical the provision of any Services under this Q.i/commerce

a personal, non-exclusive, non-transferable license to use the Software, in
object code form only, solely in connection with the Services for Customer's
internal business purposes on Customer-owned or Customer-leased equipment (the
"License"). Customer shall not use the Software (i) in connection with the

termination or expiration of this Q.i/commerce Agreement; (ii) termination of
the Service(s) with which the Software is intended for use; or (iii) failure of
Customer to comply with any provisions of this Section. Upon termination of any

copies of the Software in its possession, or (ii) return all such copies to
Qwest, and in either event provide a written officer's certification confirming
the same.

6.      Equipment or Software not Provided by Qwest.

provided by Qwest; nor shall Qwest be responsible for the transmission or
reception of information by equipment or software not provided by Qwest.

6.02 Customer shall be responsible for the use and compatibility of equipment or
software not provided by Qwest. In the event that Customer uses equipment or
software not provided by Qwest which impairs Customer's use of any Services: (a)
Customer shall nonetheless be liable for payment for all Services, including
without limitation any Software, provided by Qwest, and (b) any service
specifications or service levels generally applicable to the Services involved
shall not apply. Upon notice from Qwest that any equipment or software not
provided by Qwest is causing or is likely to cause any hazard, interference or
service obstruction, Customer shall immediately eliminate the likelihood of
hazard, interference or service obstruction and if Customer fails to do so,
Qwest may take such action as it deems required to eliminate such hazard,
interference or service obstruction.

6.03 Qwest shall not be responsible if any changes in any Services (a) cause
equipment or hardware not provided by Qwest to become obsolete or to require
modification or alteration, or (b) otherwise affect performance of equipment or
hardware not provided by Qwest.

6.04 Qwest reserves the right to allow or refuse to allow any make, model or
software revision of customer-provided equipment to be used as a gateway to any

SOFTWARE, OR THAT RESULT FROM MISTAKES, OMISSIONS, INTERRUPTIONS, DELETION OF
FILES, ERRORS, DEFECTS, DELAYS IN OPERATION, OR TRANSMISSION, OR ANY FAILURE OF
PERFORMANCE. QWEST'S LIABILITY HEREUNDER TO CUSTOMER SHALL IN NO EVENT EXCEED AN
AMOUNT EQUAL TO THE AVERAGE MONTHLY RECURRING CHARGE PAID BY CUSTOMER DURING THE
PERIOD FROM EXECUTION OF THE AGREEMENT TO THE DATE A CLAIM IS MADE.

7.06 If Customer is dissatisfied with the Services or with any terms,
conditions, rules, policies, guidelines, or practices of Qwest applicable to the

                     QWEST INTERNET ACCEPTABLE USE POLICIES

Qwest's objective is to provide and maintain the highest quality of IP services
available. Qwest must therefore maintain the integrity of not only its own
network, but the networks of the IP community at large. In order to protect not
only Qwest's network viability, but that of other networks as well, Qwest
prohibits certain practices and behaviors it deems detrimental to both its own
network and to the IP community at large by its customers and their users.

All provisions of these Internet Policies apply to Customer, and to any other
person, persons, organization, or other entity using Customer's IP services
including, but not limited to, hosted sites within the Customer's network;
co-located servers and services; Customer dialup clients; sub-letted tenants;
office-park or other dedicated IP circuit clients; business partners or other
affiliated entities or organizations; any other person, persons, organizations,
or entities whose IP traffic is either controlled, routed or processed by
Customer ("Authorized Users"). All obligations of Customer under these policies
also apply to all Authorized Users.

1.      EMAIL POLICIES

SPAM Policies:

Customers, or their Authorized Users, may not send unsolicited bulk or other
mail messages ("junk mail", "spam", or "UE") to any person who does not wish to
receive it. Customer must comply with any request to desist sending any further
mail message upon receipt of such request. Complaints to Customer about any
mail, in situations where the email recipient had inadvertently received a
legitimate bulk or other email message, must be responded to within 48 hours of
receipt of complaint.

        1) "Bulk" is defined as 25 or more electronic mail messages of the same
or substantially similar content within a 24 hour period.

        2) Unsolicited email ("UE") is any electronic mail, message, file,
program or application sent via industry standard email programs where the
recipient did not specifically ask to receive it. Email programs include Bulk
Mailers, List processors, and third-party re-mailers, and any other software
whose function includes, but is not limited to, the sending of email messages,
files, applications, and programs. Included in this list of Unsolicited Email
messages, without limitation, are commercial advertising, informational
announcements, or any other message, file, program or application. Email
recipients who subscribe to a mailing list, Listserv, registered product update
alert service, or who otherwise indicate interest in the content of the email in
a positive manner are not considered recipients of UE for the purposes of this
document.

        3) The use of third-party services to send unsolicited bulk or other
mail messages is tantamount to the Customer sending the message from its own
servers. Third-party re-mailers, processors, and "sanitizers" are those services
that for a fee or other consideration process and send Bulk or other electronic
mail, messages, files, programs, or applications on behalf of the Customer or
Client. Though transparently hiding the relay of first instance, the deleterious
effect on Qwest's network and the community at large of these mailings is the
same as if the Customer or Client had sent them out.

Other Mail Relaying:

Customer, or its Authorized Users, shall not use another non-Qwest site's mail
server to relay mail without the express permission of that site.



<PAGE>   82

        1) "Relay" is defined as (a) the configuration of any software or
program to use a non-Qwest external mail machine to send Customer Bulk or other
email in unattended mode; (b) the direct, interactive attachment to port 25 of
any non-Qwest machine to conduct a sendmail "conversation" with it for the
purposes of having that machine send the Bulk or other mail; or (c) any other
use of non-Qwest sendmail services and servers to send mail or other electronic
messages or files, whether directly or indirectly, whether the software used is
attended or unattended.

        2) Qwest servers and host may be used for relaying non-UE mail only upon
prior arrangement.

Mail Spoofing:

In no case shall the Customer use fictitious or deliberately inaccurate return
addresses in their outgoing mail ("Mail Spoofing"). This pertains to any
electronic message, file, program or application sent, whether UE or non-UE.

        1) Email Spoofing is the deliberate configuration of fictitious or
inaccurate return email usernames or domains within any outgoing email or
message. Included in this definition is the use of "Stealth" email software
which randomizes return addresses, or which uses known inaccurate or fictitious
return email addresses. Defenses to a spoofing incident may not include the
declaration of Customer ignorance of the email address a Stealth mailer may use.
Stealth software is designed and marketed to spoof email addresses.

        2) The unauthorized use of any Qwest-controlled domain in email without
the authorization of the domain registrant is prohibited.


2.      USENET NEWS SERVICE POLICIES

Customers who use Qwest's Usenet News services shall observe acceptable use
policies which apply to Usenet News. These include but not limited to the
following:

Usenet SPAM Policies:

Customers, or their Authorized Users, may not post bulk Usenet News to multiple
News groups or unrelated News groups. Bulk Usenet News is defined as posting
same News message to 5 or more News groups with unrelated content. Customer must
comply with any request to cease and desist sending any further bulk Usenet News
message upon receipt of such request.

Unacknowledged complaints, if confirmed to be legitimate, may result in
temporary suspension of Usenet News feed to Customer until the problem is
resolved.

Usenet News Spoofing Policy:

In no case shall Customer use fictitious or deliberately inaccurate return
addresses in their Usenet News postings. Confirmed News spoofing may result in
temporary suspension of Usenet News feed to Customer until the problem is
resolved.

        1) Usenet News Spoofing is the deliberate configuration of fictitious or
inaccurate return usernames or domains in any outgoing Usenet News header.



<PAGE>   83

        2) The unauthorized use of any Qwest-controlled domain in Usenet News
posts without the authorization of the domain registrant is prohibited.

3.       NETWORK - RELATED POLICIES

        In any of the following circumstances Qwest reserves the right, in its
sole discretion, to either block Customer's traffic from access to the Qwest
network or other networks, terminate on either a temporary or permanent basis
Customer's access to or interconnection with the Qwest network or any other
network, or cease provision of power or other facility support to Customer:

        1) Denial of Service attacks from Customer to other networks, verified
by Qwest using its own procedures. As used here, a "Denial of Service Attack"
means an attack to disable or disrupt the TCP/IP services, including but not
limited to TCPSYN attack, UDP Diagnostic port DoS attack, Smurfing attack or
similar attacks.

        2) Any attempts by Customer or its Authorized Users to break in to or
intrude into other networks. As used here, this includes, but is not limited to,
cracking of password files, exploiting of known or unknown security holes, or
through any other means, to gain logins and/or passwords for unauthorized access
to other networks.

        3) Deliberate or accidental Leaking of Routes. As used here, "Leaking of
Routes" means the failure to properly announce routes to Qwest according to
established protocol.

        4) Use of any third party's DNS Server without permission or consent of
the third party.

        5) Use of any third party's email server as MX backup without permission
or consent of the third party.

4.      CONTENT - RELATED POLICIES


        Although Qwest does not control, monitor, edit, approve or disapprove,
or necessarily have any knowledge of any of the content of Customer's or any
Client's servers, web pages, files, or other information, Qwest retains the
rights, in its sole discretion, to either block Customer's traffic from access
to the Qwest network or other networks, terminate on either a temporary or
permanent basis Customer's access to or interconnection with the Qwest network
or any other network, or cease provision of power or other facility support to
Customer in the event that Qwest becomes aware that Customer or any of its
Authorized Users has:

        1) Posted or transmitted any unlawful, threatening, abusive, libelous,
defamatory, legally obscene, profane or otherwise objectionable information of
any kind, including without limitation any transmissions constituting or
encouraging conduct that would constitute a criminal offense, give rise to civil
liability, or otherwise violate any local, state, national or international law,
including without limitation the U.S. export control laws and regulations;

        2) Posted or transmitted any information or software which contains a
virus, worm, Trojan horse, or other harmful component, or

        3) Uploaded, posted, published, transmitted, reproduced, or distributed
in any way, information, software or other material which is protected by
copyright or other proprietary right or derivative works with respect thereto,
without obtaining permission of the copyright owner or rightholder.

4.      CHANGE OF POLICIES AND LIMITATION OF LIABILITY



<PAGE>   84

        These policies are subject to change at any time by Qwest acting in its
sole discretion, and all such changes shall be binding upon Customer upon
written notice to Customer by Qwest.

        In the event that Qwest determines that Customer has violated or will
violate any of these policies, Qwest may take such action as Qwest solely
determines to be appropriate under the circumstances as known to Qwest at the
time such action was taken to eliminate or preclude such violation, and Qwest
shall not be liable for any damages of any nature suffered by any Customer,
Client, or third party resulting in whole or in part from its exercise of its
rights under these policies.

                    ADDENDUM C-2: DIA SERVICE LEVEL AGREEMENT

The Dedicated Internet Access Services identified on Attachment C -1("DIA
Pricing Schedule") shall be subject to the provisions of the following service
level agreement which are applicable to each such Service.

                           Qwest Network Availability

For the domestic Qwest Internet Products and Services provided to Customer under
a signed agreement with carrier, carrier IS COMMITTED TO MAINTAIN AN end-to-end
Network Availability of 99.7% based on a minimum of 10 sites and measured as
detailed below under "Calculation".

Calculation

The calculation for end-to-end network availability for a given month is as
follows:

<TABLE>
        <S>                                                                        <C>

                        (24 Hours x Days in Month x Number of Sites)
</TABLE>

Components Included

The performance of the following components of the products and services shall
be included in the determination of Network Availability.

~       All components of the Qwest Internet Network (e.g. POP to POP)

~       Carrier-provided local access facilities used to access the carrier
        Qwest Internet Network

~       Carrier-provided CSU/DSU/Channel Bank

Components Excluded

The following shall be excluded from any network outage time when calculating
the Network Availability:

~       The failure of any components beyond the Customer side of either the
        access provider demarcation or the CSU/DSU/Channel Bank if not provided
        by carrier

~       Scheduled network downtime during carrier's maintenance window

~       The failure of any components which cannot be corrected due to
        inaccessibility of Customer, or causes beyond the reasonable control of
        the carrier

Network Availability Measurement and Remedies

Network outage time in the Network Availability calculation is measured based on
the total outage time of all affected sites, subject to the included and
excluded components set forth herein. An outage condition shall exist when
Customer is unable to transmit data when recorded in the trouble ticket system.
Outage time is measured from the time the trouble ticket is opened to the time
the site is again able to transmit and receive data.

Upon verification that the actual Network Availability is below the Committed
Network Availability, Qwest shall evaluate the network and take corrective
action to remedy the problem. If the Actual Network Availability falls below the
Committed Network Availability, Qwest shall provide a service credit equal to
100 percent (100%) of one day's charge for all ports with validated outages in
the applicable day.

There shall be no caps on either monthly or yearly service credit amounts.

                        End-To-End Network availability

For domestic Qwest Internet products and services provided under this Agreement,
Qwest is committed to maintain an end-to-end network availability of 99.7%.

~       All components of the Qwest Internet Network

~       Carrier-provided local access facilities used to access the Qwest
        Internet Network (e.g. local loop)

Components Excluded

The following shall be excluded from any network outage time when calculating
the Network Availability:

~       The failure of any components beyond the premise of the Qwest
        demarcation

~       Network downtime during carrier's scheduled maintenance window

~       The failure of any components which cannot be corrected due to
        inaccessibility or causes beyond the reasonable control of Qwest

Network Availability Measurement and Remedies

Network outage time in the Network Availability calculation is measured based on
the total outage time of all affected sites, subject to the included and
excluded components set forth herein. An outage condition shall exist when a
site is unable to transmit data when recorded in the trouble ticket system.
Outage time is measured from the time the trouble ticket is opened to the time
the site is again able to transmit and receive data.

Upon verification that the actual Network Availability is below the Committed
Network Availability, Qwest shall evaluate the network and take corrective
action to remedy the problem. If the Actual Network Availability falls below the
Committed Network Availability, Qwest shall provide a service credit equal to
100 percent (100%) of one day's charge for all ports with validated outages in
the applicable day.

                        End-To-End Network Availability

For domestic Qwest Internet products and services provided under this Agreement,
Qwest is committed to maintain an end-to-end network availability of 99.7%.

Network Availability Measurement and Remedies

Network outage time in the Network Availability calculation is measured based on
the total outage time of all Customer affected sites, subject to the included
and excluded components set forth herein. An outage condition shall exist when a
site is unable to transmit data when recorded in the trouble ticket system.
Outage time is measured from the time the trouble ticket is opened to the time
the site is again able to transmit and receive data.

Upon verification that the actual Network Availability is below the Committed
Network Availability, Qwest shall evaluate the network and take corrective
action to remedy the problem. If the Actual Network Availability falls below the
Committed Network Availability, Qwest shall provide a service credit equal to
100 percent (100%) of one day's charge for all affected ports.

                     Network Delay Service Level Agreement

For the domestic Qwest Internet Service provided to Customer under a signed
agreement with carrier, carrier is committed to maintain an average, end-to-end,
roundtrip on-network delay (Committed Network Delay) as follows;

95 milliseconds for DS-3 Access (POPs located in the continental United States
only).

Calculation

The calculation for average, end-to-end, roundtrip network delay (Average
Network Delay) for a given month is as follows based on the procedure criteria
defined below:

<TABLE>
           <S>                                                    <C>
           Total End-to-End, Roundtrip Delay for All Connections  =  Average Network Delay
           -----------------------------------------------------
                         Total Number of Connections
</TABLE>

Components Included

The performance of the following components of the Products and Services shall
be included in the determination of Average Network Delay:

~       All components of the carrier Qwest Internet Network

~       Carrier-provided local access facilities used to access the carrier
        Qwest Internet Network

~       Carrier-provided CSU/DSU/Channel Bank

Components Excluded

The following components shall be excluded in the determination of Average
Network Delay:

~       Equipment beyond the Customer side of either the access provider
        demarcation or the CSU/DSU/Channel Bank if provided by carrier

~       International connections, Peering Interfaces to other ISPs and/or Qwest
        Internet Gateways to other carrier products.

Average Network Delay Measurement and Remedies

Average Network Delay will be measured by a carrier/Customer test in accordance
with the following criteria:



<PAGE>   89

~       software and hardware components capable of measuring Customer
        application traffic and responses shall be placed at each Customer site
        to be measured for roundtrip delay.

~       Total End-to-End, Roundtrip Delay Measurements shall be performed during
        the same four (4) hour period over a minimum of five (5) consecutive
        business days to adequately determine a consistent average performance
        level for the calculation.

~       Customer routers between which the data are transmitted are not more
        than fifty (50) percent utilized during the hour in which the packets
        are transmitted. Both the initiation and termination routers must be
        directly connected via a carrier Qwest Internet connection. End points
        must be located within the 48 contiguous United States.

~       The ports on both access ends between which packets are transmitted must
        not be more than fifty percent (50%) utilized during the hour in which
        packets are transmitted.

Upon verification by carrier that the actual Average Network Delay is below the
Committed Network Delay, the carrier shall take corrective action to remedy the
problem. Carrier shall have thirty (30) days from the date of such verification
to restore the Average Network Delay to the Committed Network Delay. If the
Average Network Delay is still below the committed Network Delay after such
thirty (30) day period, then, for each day that the carrier does not comply with
the Committed Network Delay, carrier shall provide Customer a service credit
equal to 50% percent (50%) of the daily charge for all Ports with validated
outages for the applicable day on a retroactive basis from the date of
verification.

There shall be no caps on either monthly or yearly service credit amounts.

                         Maintenance Window Definition

The maintenance window defines the process for normal upgrades of hardware and
software in a reasonable time frame, giving adequate warning to affected
customers.

There are three levels of urgency for upgrades and fixes:

1.      Normal outages for increasing capacity or upgrading software. Normal
        outages fit into a weekly window in the local off peak hours, with 2 or
        more business day notice to customers.

2.      More urgent problems that degrade service but don't always require
        immediate repair. Maintenance is performed in the local off peak hours,
        with as much notice as possible.

3.      Service affecting problems that must be fixed immediately. These
        services can take place at any time, with notification as soon as
        possible.

                      TELECOMMUNICATIONS SERVICES AGREEMENT

                               REVENUE COMMITMENT

1. REVENUE COMMITMENT: Customer acknowledges and agrees that certain rates,
charges and discounts are provided to Customer in consideration of Customer's
agreement to meet or exceed the revenue commitments established in this Exhibit
D, and that such rates, charges and discounts would not be offered to Customer
without Customer's agreement to make such commitments. The parties agree that
any agreed-upon true up payments, deficiency charges, early termination fees or
other relief (the "Commitment Remedies") set forth in this Exhibit D to any
agreed-upon revenue commitments represent mutual good faith estimates of, and
bear reasonable relationships to, the actual damages of Qwest in the event of a
failure by Customer to meet or exceed such revenue commitments. The parties
further agree that such Commitment Remedies do not represent a penalty of any
kind and shall be obligations of Customer subject to specific performance.

1.1     During the Term of the Agreement, Customer commits to purchase Services
        from Qwest in accordance with the amounts set forth in Table D-1 below
        ("Total Minimum Revenue Commitment"). Revenue from any collocation
        agreements entered into by the parties shall not contribute toward the
        Total Minimum Revenue Commitment or the Minimum Revenue Commitment. The
        "Commitment Period" of the Agreement shall not commence until Qwest
        delivers to CUSTOMER any Facility pursuant to the terms of this
        Agreement.

1.2     In the event CUSTOMER fails to meet its minimum revenue commitment
        ("MRC") as identified in Table D-1 and Qwest has otherwise fulfilled its
        material obligations to CUSTOMER, Qwest shall be entitled to a true up
        payment for the short fall in services purchased during that period.
        This true up payment shall be due and payable within fifteen (15) days
        of receipt of such true up invoice from Qwest after the end of such
        period. In the event that the services or purchases

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

    throughout this exhibit.

<PAGE>   92

        paid for by CUSTOMER during any period of the contract term are in
        excess of the MRC for such period, CUSTOMER shall have the option to
        either 1) apply such excess toward the subsequent period; or 2) apply
        such excess, or a portion thereof, as a credit payment for services;
        provided, however, that option (2) herein shall only be available if
        CUSTOMER has previously made a true up payment to Qwest; and the amount
        of credit payment for services shall be limited to the amount of such
        previously paid true up payment by CUSTOMER. In the event that such
        excess amount is greater than the amount of any previous true up payment
        and CUSTOMER elects option (2), the difference between such excess
        amount and true up payment shall be applied toward the next MRC in
        accordance with option (1).

1.3     Qwest will provide CUSTOMER a "Meet the Market" option that will apply
        to the price of Qwest services being purchased by CUSTOMER. This option
        provides that Qwest will meet the rates as set forth in any bona fide
        offer received by CUSTOMER for like services, like guaranteed service
        level agreement and like term of agreement, provided, that CUSTOMER
        shall provide to Qwest sufficient documentation evidencing such bona
        fide offer. If Qwest opts to not meet the bona fide service offer,
        CUSTOMER's sole remedy shall be to terminate the Agreement without any
        further obligation to Qwest, and without any Termination Charge as
        specified in Section 3 herein. This option will be exercisable for
        Switched Voice Services only on an annual basis, in months [*]. For all
        other communication services purchased by CUSTOMER, this option will
        only be exercisable by CUSTOMER in month [*] and month [*] of the
        Agreement.

1.4     In the event that CUSTOMER exceeds the Total Minimum Commitment detailed
        in Table D-1 prior to the expiration of the Initial Term, CUSTOMER shall
        have the option to renegotiate or expand the terms of the TSA

2.      CONTRACT ESCROW:

        2.1 CUSTOMER shall deliver the following payments to Qwest as an
        additional assurance of contract commitment ("Total Minimum Commitment")
        detailed above. Should CUSTOMER fail to meet or exceed the first Minimum
        Revenue Commitment ("MRC") for the first commitment period ([*] for
        Months 0 - 36) the Contract Escrow payments detailed below, plus earned
        interest, shall: 1) if greater than the MRC shortfall, be utilized to
        make the true up payment with the excess amount over the MRC shortfall
        applied against CUSTOMER's subsequent service invoice(s), or 2) if less
        than the MRC shortfall, be remitted to Qwest in addition to payment of
        the MRC shortfall payment. However, if CUSTOMER exceeds the MRC for the
        first commitment period [*] for Months 0 - 36), the Contract Escrow
        payments detailed below, plus earned interest, shall be

3.      TERMINATION CHARGE:

3.1     At any time after the Effective Date through the end of the Term,
        Customer may terminate this Agreement in its entirety, without cause, by
        delivering to Qwest a written notice of termination. Customer shall, in
        the event that it exercises its right to terminate for convenience
        hereunder, pay Qwest (in certified funds) the applicable termination
        charge ("Termination Charge") calculated as set forth in Section 3.2
        below. In the event that the Total Minimum Commitment has been fully
        satisfied, Customer may terminate this Agreement without payment of any
        Termination Charge. The notice of termination shall set forth the
        effective date for termination of the Agreement, and the Termination
        Charge shall be due and payable within thirty (30) days after Customer's
        receipt of the final invoice for Services delivered prior to the
        effective date of termination.

3.2     In the event Customer elects to exercise its right to terminate this
        Agreement for convenience under Section 3.1 above, Customer shall pay to
        Qwest a Termination Charge calculated as follows:

        (a)    If the amount actually paid by Customer for all Services and
               Products delivered through the date of termination of the
               Agreement is less than [*], then the difference between fifty
               percent (50%) of the Total Minimum Commitment (or [*]) and the
               amount actually paid by Customer for all Services delivered to
               through the date of termination of the Agreement; plus

        (b)    fifty percent (50%) of the remaining Total Minimum Commitment.

        Two examples of the method for calculation of the Termination Charge are
        set forth below:

        provide CUSTOMER with a discount from negotiated base rates equal to the
        greater of i) the actual monthly dollar volume for switched voice
        services achieved by CUSTOMER, or ii) the amortized monthly dollar
        volume associated with the Total Minimum Commitment (i.e.; [*]) as
        detailed in Table D-1. The volume discount structure utilized will be as
        contained in Qwest's standard wholesale switched voice services product
        offering (as set forth in the Carrier Services Agreement dated July 14,
        1998 provided to CUSTOMER) plus an additional two percent (2%)
        consideration for the expanded term of the Total Minimum Commitment
        period, the total discount from base rates not to exceed 15% at any
        time. Only the true up payment defined in Section 1.2 of this Exhibit D
        shall apply.

4.3     In consideration of the Total Minimum Commitment, Qwest Wholesale
        Markets Division will, for ATM Services purchased from Qwest, provide
        CUSTOMER with a discount from base rates equal to the greater of i) the

        (b)     Detailed Restoration Plan

                (1)     Restoration activities will be integral to ensuring
                        successful implementation of this Agreement. Timely
                        restoration is dependent upon the timely coordination
                        and cooperation between Bonneville and ATG. The Parties
                        agree to jointly develop a Detailed Restoration Plan,
                        which shall, upon its completion become part of this

                (1)     Bonneville's obligation to maintain and repair the Cable
                        and any activity incidental thereto shall be subordinate
                        to, and shall not conflict with, Bonneville's rightful
                        use and operation of its transmission facilities. In the
                        event both Bonneville's transmission facilities and the
                        Cable require maintenance or repair, the restoration of
                        the Cable shall be at all times subordinate to the
                        restoration of Bonneville's transmission facilities,
                        unless otherwise agreed to by Bonneville in advance. The

                        to ATG Fiber as shall restoration rights contained in
                        pre-existing contracts. The restoration of the ATG Fiber
                        shall take priority over restoration activities related
                        to any fibers licensed in contracts subsequent to the
                        agreement.


                                                                               6
<PAGE>   7

                (2)     Any and all Bonneville or ATG representatives that
                        construct, install, repair, replace, or otherwise handle
                        the Cable, Cable Accessories, ATG Fiber, Bonneville
                        Fiber, or any related materials and equipment shall be
                        properly trained and equipped to meet all current
                        industry standards.

                (3)     A Bonneville representative must be on site during all
                        repair and restoration work to perform functions such as
                        safety watch, protection of Bonneville's transmission
                        facilities, or obtain line clearances. Bonneville shall
                        make its best efforts to have a representative arrive
                        at the site requiring an emergency maintenance activity
                        pursuant to section 8(d)(1) of this Agreement.

                (4)     The Party performing the repair and restoration shall
                        use prudent business methods to acquire the most cost
                        effective restoration procedures and materials
                        available given the Cable Specifications, Fiber
                        Specifications, and current industry standard.

                (5)     Bonneville shall require all employees or agents of ATG
                        who work near Bonneville's transmission facilities to
                        demonstrate that they have been properly trained and
                        equipped to perform the work. The Parties shall agree in
                        advance what constitutes proper training and reasonable
                        costs. The costs of agreed upon training for ATG
                        employees or agents of ATG shall be borne by ATG.

                (6)     A Bonneville representative shall have the authority to
                        stop work for reasons that involve potential health
                        hazards, safety concerns, and potential disruption to
                        Bonneville's operating system.

        (d)     Restoration of the Cable

                (1)     Bonneville shall immediately, upon notification from
                        ATG, of a confirmed cable related interruption in
                        service, failure, disrepair, impairment or other need
                        for repair or restoration of the ATG Fiber, begin to
                        mobilize Bonneville crews and make its continuous best
                        effort to achieve such necessary repair or restoration,
                        including making its best effort to have maintenance
                        personnel at the affected site within four (4) hours
                        after receipt of such notice, provided, however, that in
                        the event any of ATG rights are interrupted by events
                        described in section 18(a), repairs and restoration
                        shall be made as expeditiously as possible consistent
                        with section 8(c)(1). ATG recognizes that the four (4)
                        hour response time represents optimal conditions, and
                        may be impossible to achieve when responding to certain
                        remote locations. Actual response times will be
                        influenced by factors such as the terrain, weather
                        conditions present at the time the request is made, and
                        the actual mileage from Bonneville's dispatch station to
                        the fault site.


                                                                               7
<PAGE>   8

                (2)     For purposes of this section, best efforts means
                        activities and performance consistent with prudent
                        utility practice, existing contract provisions for
                        Bonneville's hourly employees ("Collective Agreement
                        between BPA and Columbia Power Trades Council"), and
                        response times that do not jeopardize the health and
                        safety of Bonneville employees, agents of Bonneville,
                        ATG employees or agents of ATG.

                (3)     The Detailed Restoration Plan shall set forth the roles
                        and responsibilities of the respective parties, and
                        shall address issues regarding logistical
                        considerations, response interval factors, communication
                        between the Parties, sequential activity requirements,
                        and other related items which would impact response time
                        and restoration intervals. The aforementioned issues
                        will be taken into consideration in the determination of
                        whether Bonneville has used its best efforts in such
                        restoration or repair activities.

                (4)     If Bonneville is unable to begin to provide restoration
                        within the agreed-upon timeframe pursuant to section
                        8(d)(1), Bonneville shall provide ATG or its Bonneville-
                        approved subcontractor access to the Cable, pursuant to
                        the Detailed Restoration Plan, after notification from
                        ATG of confirmed cable related interruption in service,
                        failure, disrepair, impairment, or other need for
                        repair, so that ATG or its Bonneville-approved
                        subcontractor can make necessary repairs to the Cable
                        provided such repairs are made in accordance with all
                        current Bonneville and industry safety standards.

                (5)     Given that the Cable has been maintained by Bonneville
                        pursuant to 9(a)(1), and if the cable's ability to
                        transmit a signal degrades over time to a level
                        unacceptable to either Party, the Parties will jointly
                        determine the action to be taken and share any costs
                        associated with the action on a pro rata basis based
                        upon the number of fibers in each Party's control.

9.      REGENERATOR BUILDING(S)

        (a)     ATG shall have sole responsibility for the expense and
                acquisition of any property or utilities necessary for its
                equipment along the Route. If space is available at Bonneville
                substations, such space shall be provided to ATG pursuant to the
                Regenerator Site Lease Agreement form attached as Exhibit D.

        (b)     Other than the Bonneville Facilities, ATG shall provide and own
                the Cable Accessories splice boxes, and other components
                necessary for the operation of the ATG Fiber as set forth in
                Exhibit D.


                                                                               8
<PAGE>   9

        (c)     Bonneville will provide to ATG the Bonneville Safety
                Requirements. ATG shall have sole responsibility to comply with
                Bonneville Safety Requirements with regard to the installation
                and maintenance of ATG facilities on or about Bonneville's
                right-of-way and property. ATG's compliance with Bonneville
                Safety Requirements and for maintenance of certain environmental
                control procedures such as maintenance of the grounds around the
                Regenerator Building(s) will be at ATG's expense.

        (d)     ATG may use Bonneville's access roads to access the Regenerator
                Building(s), provided that heavy vehicles or other equipment
                being used on the access road will not impair the use of the
                access road by Bonneville. Access to the roads shall be limited
                to the times and frequency required for maintenance and
                operation of the Regenerator Building(s) and equipment, and any
                repair and restoration of the Cable pursuant to section 8. ATG
                shall at ATG's expense repair any damage to the access roads
                caused as a result of ATG use of the access roads.

10.     RIGHTS AND OBLIGATIONS CONCERNING THE CABLE

        (a)     Permits

                Bonneville shall acquire all necessary regulatory or
                governmental permits and approvals with the exception of any
                permits and/or approvals that may be required for the
                Regenerator Building(s). Additionally, Bonneville shall acquire
                all necessary National Environmental Policy Act (NEPA) permits
                for the Regenerator Building(s) pursuant to paragraph (d) of
                this section.

                When feasible and necessary, Bonneville shall acquire permits,
                easements, or additional rights-of-way for the Regenerator
                Building(s) provided ATG pays for the full cost of such
                assistance and protects Bonneville from future liability
                resulting from such actions.

        (b)     Taxes, Mechanic's Liens, and Encumbrances

                ATG shall pay its own income taxes as well as all franchise fees
                and other fees and taxes resulting from ATG License over the ATG
                Fiber along the Route. ATG shall keep the Route free from all
                liens and encumbrances resulting from its performance of this
                Agreement. If ATG does not pay the foregoing taxes and fees when
                such become due, and such nonpayment results in the imposition
                of a lien on, or encumbrance of, the Route, then Bonneville
                shall have the right, but not the obligation, to pay all amounts
                due and discharge such lien or encumbrance, upon thirty (30)
                calendar days prior written notice to ATG and charge the amount
                thereof to ATG. In the event Bonneville causes such liens or
                encumbrances to be discharged, ATG shall pay such amounts to
                Bonneville upon demand together with interest thereon at the
                Interest Rate, accruing from the date that Bonneville makes
                payment discharging such liens or encumbrances until the date
                Bonneville receives full reimbursement from ATG. ATG shall have
                the absolute right to dispute or challenge any tax or fee
                assessed on its use of the ATG Fibers.


                                                                               9
<PAGE>   10

        (c)     Access to Local Landowners

                Contacts made by ATG with local landowners adjacent to the Route
                shall be coordinated with Bonneville as specified in the
                Detailed Restoration Plan.

        (d)     Environmental Compliance Activities

                Bonneville shall be responsible for compliance with the Federal,
                State, and local laws and regulations pertaining to NEPA and
                related public involvement and information exchange in relation
                to the proposed project activities. Bonneville shall acquire all
                necessary permits associated with the project operations,
                maintenance, and construction. The project activities will be
                limited to construction and operation of cable, hardware;
                Regenerator Building(s), access roads and distribution lines if
                needed for Regenerator Building(s). If any mitigation measures
                are identified as part of the NEPA compliance activities, these
                measures will be performed by Bonneville at the sole cost of ATG
                provided, however, that ATG shall not be liable for the costs of
                any mitigation measures that arise from activities unrelated to
                activities authorized by this Agreement. Contacts with the local
                landowners will be performed by Bonneville-appointed
                representatives. Any landowner compensation required as part of
                the NEPA and project activities will be made by ATG. All of the
                compliance activities undertaken by Bonneville pursuant to this
                subparagraph shall be at the cost and expense of ATG.

        (e)     Taxes, title to and ownership of the ATG Fiber shall remain in
                Bonneville which will be responsible for ad valorem taxes, if
                any, imposed on its ownership of the ATG Fiber. If requested in
                writing, Bonneville will reasonably assist ATG in any dispute or
                challenge of any tax or fee assessed that ATG believes should be
                properly assessed based on the ownership of the ATG Fiber.

11.     RELOCATION OF THE CABLE

        The Cable or a portion thereof may require relocation or replacement
        during the term of this Agreement. The cost of such relocation or
        replacement shall be allocated as follows:

        (a)     If requested by ATG for its operational purposes, ATG shall pay
                all such costs, provided, however, that Bonneville shall, in its
                sole discretion, determine whether such relocation of the Cable
                may be accommodated considering Bonneville's own need to provide
                economical and reliable electric power;

        (b)     If requested by Bonneville due to requirements necessary to
                provide economical and reliable electric power, Bonneville shall
                pay all such costs;


                                                                              10
<PAGE>   11

        (c)     If the Cable must be relocated due to the order of any court or
                governmental agency, or because of a force majeure event
                Bonneville shall, in consultation with ATG designate a new route
                for the Cable. The costs associated with such required
                relocation that are not paid by a third party, shall be
                allocated between the Parties on a pro rata basis.

        (d)     If the Cable must be relocated pursuant to section 11(c) above,
                Bonneville and ATG shall work together to select contractors and
                materials to achieve the most cost effective relocation
                available in the market place given the Cable Specifications
                Fiber, Specifications, and current industry standards.

12.     REPRESENTATIONS AND WARRANTIES

                (2)     There are no known actions, suits, or proceedings
                        pending or overtly threatened against ATG before any
                        court or administrative agency that would materially
                        impair ATG's performance of its obligations under this
                        Agreement.

        (b)     Bonneville represents and warrants to ATG as follows:

                (1)     Bonneville is duly authorized to execute and deliver
                        this Agreement and to perform its obligations hereunder.
                        This Agreement constitutes a legal and valid obligation
                        of Bonneville enforceable in accordance with its terms
                        to the full extent provided by law. The enforceability
                        of this Agreement is qualified as to:


                                                                              11

                                arrangement, moratorium, or other laws relating
                                to or affecting the enforcement of creditor's
                                rights generally.

                (2)     Upon execution of this Agreement, Bonneville warrants
                        that there are no known conflicts with this Agreement
                        and that neither execution and delivery of this
                        Agreement nor performance by Bonneville of its
                        obligations hereunder constitutes a material breach of

                        law or administrative regulation, or violate any
                        judgment, decree, or other instrument, or any other
                        contract related to the Route to which Bonneville is a
                        Party or to which Bonneville or any of its property or

                                                                              12

                        periods for all materials it is responsible to procure,
                        and shall use reasonable efforts to obtain longer
                        warranty periods, if such extended warranties do not
                        materially increase the cost of such materials. Each
                        Party's sole obligation and liability to the other with
                        respect to the materials warranties shall be to
                        administer such warranties. In no event shall either
                        Party be deemed to have guaranteed any such warranties
                        provided by vendors or suppliers.

                (4)     Each Party will cooperate and assist the other with
                        respect to any claim that a Party may assert against
                        vendors and suppliers under such warranties, including
                        such reasonable actions as may be necessary to assign or
                        otherwise make available to a Party the right to make
                        such claims.

        (d)     No Bonneville Warranty Concerning Route

                Bonneville makes no representation or warranty whatsoever
                concerning the physical characteristics of the Route. ATG
                acknowledges that neither Bonneville nor any of Bonneville's
                officers, employees, representatives, contractors, or
                subcontractors or agents have made any such representation, nor
                is Bonneville or ATG entering into this Agreement in reliance
                upon any such representation or warranty.

13.     AUDIT PROCEDURES

        (a)     Records

                The Parties shall maintain true and correct sets of records in
                connection with the performance of this Agreement and all
                transactions related thereto and shall retain all such records

                Effective Date has been provided in accordance with section 2 of
                this Agreement. The Parties shall also maintain true and correct
                sets of records in connection with its accounting, billing, and

        (b)     Reimbursement

                If Bonneville or ATG is entitled under this Agreement to be paid
                amounts determined in whole or in part on a reimbursement of
                costs basis, the costs to be reimbursed shall be only those
                reasonably necessary to perform the work in an efficient manner
                in accordance with the time schedule required.


                                                                              13

        (c)     Audit Rights

                Notwithstanding anything in this Agreement to the contrary,
                either Party which is required to make payment under this
                Agreement, may, at the paying Party's sole discretion and
                expense, request and perform a complete audit of the records of
                the Party requesting reimbursement which are described in
                Paragraph 14(a) above. In the event that the Parties agree that
                the auditing Party's audit is determined to be correct, the
                nonauditing Party shall reimburse the auditing Party the agreed
                upon amount. In the event that the nonauditing Party disagrees
                with the results of the Party's audit and resolution is not
                reached between the Parties, the Parties agree to resolve the
                dispute pursuant to Section 17 of this Agreement.

15.     DEFAULT

                If either Party is in material breach or default (Defaulting
                Party), under this Agreement, the other Party (Nondefaulting
                Party) may notify in writing the Defaulting Party that it is in

                        answer seeking or acquiescing in any reorganization,


                                                                              16

                        creditors;

                (5)     willful and material interference by one Party to the
                        other Party's operations; or

                (6)     failure to make full restitution for any damage to one
                        Party's real property or equipment caused as a result of
                        the sole negligent or willful actions by the other
                        Party.

        (b)     Remedies

                (1)     Defaulting Party's Right to Cure

                        The Defaulting Party shall have the right to cure any
                        material breach or default under this Agreement within
                        thirty (30) calendar days after the receipt by the
                        Defaulting Party of notification of such material breach
                        or default. In the case of any material breach or
                        default which may not reasonably be cured within thirty
                        (30) calendar days, the Defaulting Party shall have the
                        right to provide the Nondefaulting Party with a plan for
                        the appropriate actions to cure such material breach or
                        default. Within the thirty (30) calendar day period, the
                        Defaulting Party must commence diligently pursuing
                        appropriate action under the plan to cure the material
                        breach or default, in which event the Defaulting Party
                        shall have a longer period of time to cure the material
                        breach or default so long as the Defaulting Party shall
                        continue to be diligently pursuing appropriate action
                        during such period; provided, however, that in no event
                        shall such time period exceed one hundred twenty (120)
                        days.

                (2)     Nondefaulting Party's Remedies

                        After the time allowed the Defaulting Party to cure any
                        material breach or default has expired, then the
                        Nondefaulting Party shall have the right to: (A)
                        terminate this Agreement; (B) cure any material breach
                        or default of the Defaulting Party to preserve the
                        Nondefaulting Party's rights that may be prejudiced as a
                        result of such material breach or default; and (C)
                        exercise and pursue all other rights and remedies
                        available to it under applicable law.


                                                                              17
<PAGE>   18

                (3)     Rights and Remedies Cumulative

                        Except as otherwise provided in this Agreement, any
                        right, or remedy afforded to either ATG or Bonneville
                        under any provision of this Agreement on account of
                        material breach or default by the other is in addition
                        to, and not in lieu of, all rights or remedies afforded
                        either ATG or Bonneville under any other provision of
                        this Agreement, by law or otherwise on account of the
                        material breach or default.

16.     INDEMNIFICATION; WAIVER OF DAMAGES.

        (a)     Indemnification by ATG

                (1)     To the extent allowed by law, ATG shall release and
                        indemnify, defend, and hold harmless Bonneville and each
                        of its directors, officers, agents, representatives,
                        subcontractors, and employees (the "Bonneville
                        Indemnitees") from and against any and all liabilities,
                        losses, claims, demands and actions of any nature
                        ("Claims") for injury to or death of a person, including
                        an employee of ATG or a Bonneville Indemnitee, or for
                        loss of or damage to property resulting directly or
                        indirectly from ATG's performance or nonperformance of
                        this Agreement, except to the extent that such Claim is
                        the result of negligence or willful misconduct of a
                        Bonneville Indemnitee.

                (2)     ATG accepts responsibility and liability, whether now
                        existing or arising, in connection with any Federal or
                        state statute, law, ordinance, regulation or judgment
                        related to the existence, disposal, or release of
                        hazardous waste, contaminants or pollutants, including
                        but not limited to polychlorinated biphenyl (PCB) on the
                        Route, directly or indirectly resulting from or caused
                        by ATG or ATG performance or nonperformance of this
                        Agreement.

                (3)     If negligence nor willful misconduct of a Bonneville
                        Indemnitee has contributed to a Claim, ATG shall not be
                        obligated to indemnify the Bonneville Indemnitees for
                        the proportionate share of such Claims caused by such
                        negligence or willful misconduct. Bonneville shall have
                        the right, at its own cost, to retain counsel, to
                        monitor, or participate in the defense of any Claim that
                        is covered by ATG's indemnity hereunder. Bonneville
                        shall reimburse ATG for that portion of a Claim
                        determined or agreed to be caused by Bonneville's
                        negligence or willful misconduct. Reimbursement shall be
                        due to ATG thirty (30) calendar days after the
                        determination or agreement with respect thereto, and
                        shall bear interest at the Interest Rate from said date
                        until the date of payment by Bonneville.


                                                                              18

        (b)     Indemnification by Bonneville

                (1)     To the extent allowed by law, Bonneville shall release
                        and indemnify, defend, and hold harmless ATG and each of
                        its directors, officers, agents, representatives,
                        subcontractors, and employees (the "ATG Indemnitees")
                        from and against any and all Claims as defined in
                        section 16(a)(1) for injury to or death of a person,
                        including an employee of Bonneville or an ATG
                        Indemnitee, or for loss of or damage to property
                        resulting directly or indirectly from Bonneville's
                        performance or nonperformance of this Agreement, except
                        to the extent that such Claim is the result of
                        negligence or willful misconduct of a ATG Indemnitee.

                (2)     Bonneville accepts responsibility and liability, whether
                        now existing or arising, in connection with any Federal
                        or state statute, law, ordinance, regulation or judgment
                        related to the existence, disposal, or release of
                        hazardous waste, contaminants or pollutants, including
                        but not limited to PCB on the Route, directly or
                        indirectly resulting from or caused by Bonneville or
                        Bonneville's performance or nonperformance of this
                        Agreement.

                (3)     If negligence or willful misconduct of a ATG Indemnitee
                        has contributed to a Claim, Bonneville shall not be
                        obligated to indemnify the ATG Indemnitees for the
                        proportionate share of such Claims caused by such
                        negligence or willful misconduct. ATG shall have the
                        right, at its own cost, to retain counsel, to monitor,
                        or participate in the defense of any Claim that is
                        covered by Bonneville's indemnity hereunder. ATG shall
                        reimburse Bonneville for that portion of a Claim
                        determined or agreed to be caused by ATG's negligence or
                        willful misconduct. Reimbursement shall be due to
                        Bonneville thirty (30) calendar days after the
                        determination or agreement with respect thereto, and
                        shall bear interest at the Interest Rate from said date
                        until the date of payment by ATG.

                (4)     Bonneville agrees to indemnify ATG against any claims of
                        underlying landowners along the Route of damage to
                        property resulting from Bonneville's construction and
                        maintenance of the Cable.

        (c)     Waiver of Certain Damages

                Each Party hereby waives any right to consequential, incidental,
                special or indirect damages, or damages for lost profits or
                exemplary damages with respect to any claim arising out of or
                related to this Agreement. The Parties acknowledge that the
                foregoing waiver shall not prejudice the right of indemnity
                respecting any Claim under this section.


                                                                              19

<PAGE>   20
        (d)   The provisions of this section shall survive the expiration or
              termination of this Agreement.

17.     DISPUTE RESOLUTION

        (a)   Pending resolution of a disputed matter, the Parties shall
              continue performance of their respective obligations hereunder.
              Any controversy between the Parties rising out of this Agreement
              or breach thereof, or out of performance under this Agreement, is
              subject to the mediation process described below. If not resolved
              by mediation, then the matter must be submitted to the American
              Arbitration Association ("AAA") for arbitration before a sole
              arbitrator.

        (b)   A meeting will be held promptly between the Parties to attempt in
              good faith to negotiate a resolution of the dispute. The meeting
              will be attended by individuals with decision-making authority
              regarding the dispute. If within thirty (30) calendar days after
              such meeting the Parties have not succeeded in resolving the
              dispute, either party may within thirty (30) calendar days
              thereafter serve written notice to the other party and submit the
              dispute to a mutually acceptable third-party mediator who is
              acquainted with dispute resolution methods. If the dispute is not
              resolved by mediation either Party may initiate arbitration with
              the AAA, upon the written notice from either Party to the other
              Party. The dispute shall be resolved by arbitration under the
              AAA's Complex Commercial rules. The arbitrator's authority shall
              be limited by Federal Law. Judgment upon the award rendered by the
              arbitrator may be entered in any court having jurisdiction
              thereof. Neither Party is entitled to seek or recover punitive
              damages in considering or fixing any award under these
              proceedings.

        (c)   The costs of mediation and arbitration, including any mediator's
              fees, AAA administration fee, the arbitrators fee, and costs for
              the use of facilities during the hearings," shall be borne equally
              by the Parties. Reasonable attorneys' fees may be awarded to the
              prevailing Party (provided such a Party can clearly be determined
              from the proceedings) at the discretion of the arbitrator. Each
              Party's other costs and expenses will be borne by the Party
              incurring them.

18.      GENERAL

        (a)   Force Majeure

              (1)   As used in this Agreement, the term "Force Majeure" means
                    acts of God (including but not limited to, earthquakes,
                    fires, floods, windstorms, landslides, and ice storms);
                    strikes, lockouts, or other labor disputes; acts of public
                    enemy; acts of vandalism, wars, riots,



                                                                              20

                    and insurrection; epidemics; civil disturbances; explosions;
                    train derailments; breakdown or failure of machinery or
                    facilities (excluding the Cable and Cable Accessories);
                    accidents to machinery or equipment (excluding the Cable and
                    Cable Accessories), and delay in delivery of equipment to
                    the extent such occurrences are beyond the reasonable
                    control of the Parties; electrical disturbance originating
                    in or transmitted through such Party's electrical system or
                    equipment or any electrical system with which such Party's
                    system or equipment is interconnected; and any other event,
                    cause, or condition beyond the party's reasonable control,
                    which, by the exercise of reasonable diligence, prevents the
                    Party claiming Force Majeure from performing its obligations
                    under this Agreement.

              (2)   If either Party is unable to carry out its obligations
                    under this Agreement as a result of an event, cause, or
                    condition of Force Majeure, the Party claiming Force Majeure
                    shall give notice and full particulars of such Force Majeure
                    in writing to the other Party within five (5) calendar days
                    at the beginning of the occurrence of the Force Majeure
                    event, cause, or condition. Any obligations that such Party
                    is unable to perform due to an event, cause, or condition of
                    Force Majeure shall be suspended during the continuance of
                    such event of Force Majeure. The Party claiming Force
                    Majeure shall use reasonable efforts to remedy and minimize
                    the effects of such event of Force Majeure with all
                    reasonable dispatch.

              (3)   Neither Party shall be liable under this Agreement for, or
                    be considered to be in material breach or default under,
                    this Agreement on account of any delay in or failure of
                    performance due to Force Majeure unless specifically stated
                    in this Agreement.

              (4)   If Bonneville is the Party claiming Force Majeure and such
                    event of Force Majeure prevents restoration by Bonneville or
                    ATG within one (1) year from the event of such Force
                    Majeure, then ATG shall have the option to terminate this
                    Agreement under the provisions of section 15(b)(1).

        (b)   Notices

              All notices and other communications under this Agreement shall be
              properly given only if made in writing; and

                    prepaid; or



                                                                              21

                    forth in this section 18(b) or such other address or
                    facsimile number as such Party may designate by notice to
                    the other Party. Such notices and other communications
                    shall be effective on the date of receipt. If any such
                    notice or communication is not received or cannot be
                    delivered due to a change in the address of the receiving
                    Party of which notice was not previously given to the
                    sending Party or due to a refusal to accept by the receiving
                    Party, such notice or other communication shall be effective
                    on the date delivery is attempted.

                            SINGLE-MODE OPTICAL FIBER



GENERAL

Corning(R) SMF-28(TM) single mode fiber is considered the "standard" optical
fiber for telephony, cable television, submarine, and private network
applications in the transmission of data, voice, and/or video services. Corning
SMF-28 fiber is manufactured to the most demanding specifications in the
industry.

SMF-28 fiber is optimized for use in the 1310 nm wavelength region. The
information carrying capacity of the fiber is at its highest in this
transmission window, and it is also where dispersion is the lowest. SMF-28 fiber
can also be effectively used in the 1550 nm wavelength region.

Corning's enhanced, dual layer acrylate CPC6 coating provides excellent fiber
protection and is easy to work with. CPC6 can be mechanically stripped and has
an outside diameter of 245 (Micron)m. CPC6 is optimized for use in many single
and multi-fiber cable designs including loose tube, ribbon, slotted core, and
tight buffer cables.

SMF-28 fiber is manufactured using the Outside Vapor Deposition (OVD) process,
which produces a totally synthetic, ultra-pure fiber. As a result, Corning
SMF-28 has consistent geometric properties, high strength, and low attenuation.
Corning SMF-28 fiber can be counted on to deliver excellent performance and high
reliability, reel after reel.

FEATURES AND BENEFITS

- - Versatility in 1310 nm and 1550 nm applications.

- - Outstanding geometrical properties for low splice loss and high splice yields.

- - OVD manufacturing reliability and product consistency.

- - Optimized for use in ribbon, loose tube, and other common cable designs.

                          ACCEPTANCE TESTING STANDARDS


Bonneville shall meet the Acceptance Testing Standards set forth below. In the
event Bonneville's performance requirements for its communications system
requires Bonneville to exceed the standards and requirements specified in this
Exhibit, Bonneville shall apply the higher standard.

Client Network Span and Final Acceptance Requirements:

1.      DESIGN CRITERIA

        The number of cable splices at the time of original construction will be
        designed to maximize reel lengths between splices. Due to cable cuts,
        project changes and cable relocation, additional splices may be
        necessary and are allowed. The number of splices will be monitored to
        insure that attenuation and reflection tolerances are maintained.

2.      CONSTRUCTION

        Cable must be constructed in accordance with sound commercial practices.
        Bonneville requirements will in general be more stringent however. The
        National Electric Code shall be followed as a minimum.

3.      TYPICAL FIBER CABLE INFORMATION

        Single mode fiber specifications may vary, depending on the fiber
        manufacturer. Typical concatenated levels of 0.40 dB per km @ 1310nm
        (for SMF-28) and 0.25 per km @ 1550nm (for SMF-28 fibers and LEAF(TM)).

4.      SPAN REQUIREMENTS

        Span loss measurements must be performed using the two following
        methods: OTDR (optical time domain reflectometer) and insertion loss
        (stabilized light source and power meter) measurement in each direction
        at 1550nm wavelength. Insertion loss testing will not be completed until
        Client fibers have been terminated at each site.

        (a)   Maximum dB/km loss must not exceed 0.35 dB/km at 1550nm including
              splice losses.



                                  Page 1 of 3
<PAGE>   34

        (b)   In no case shall a fiber show a point discontinuity greater than
              0.1dB. Discontinuities (known as steps, splices, or attenuation
              non-uniformity's) shall be measured with an OTDR to determine the
              loss of the localized attenuation. The least squares fit method of
              measurement must be used to determine the magnitude of the loss of
              a point discontinuity.

        (c)   Client shall provide Bonneville access to it's fiber termination
              panels at each but on the route to perform these measurements.

        (d)   Preliminary power meter testing consisting of a mechanical fiber
              coupler, stabilized light source and a power meter (to assure that
              no transposed fibers are spliced) may be completed within 60 days
              of the completion of construction.

        (e)   Test data including OTDR trace data in hard copy or electronic
              format must be submitted to Client within 60 days of Bonneville's
              receipt of a written request for this data. This data will not be
              available until after construction is complete.

In the event the measured span values exceeds the calculated values, Bonneville
will perform corrective maintenance as required to restore the Commercial Fiber
to the tolerances noted in this exhibit.

5.      SPLICE LOSS

        The bi-directional splice loss average shall be 0.l0dB or less over the
        span. All splicing will be performed by the proprietor pursuant to the
        Fiber Lease Agreement. All fiber splicing must be fusion type.

6.      COMPLIANCE

        Client, at its discretion, may choose to physically monitor any or all
        testing associated with acceptance of the Commercial Fiber. If requested
        in writing test data including OTDR trace data in- hard copies or
        electronic form must be submitted to Client for review. Client has the
        option to waive any specifications and/or requirements listed in the
        technical specification criteria by providing written notice to
        Bonneville.

<PAGE>   35

7.      KEY OPTICAL PERFORMANCE CHARACTERISTICS REQUIRED FOR SINGLE-MODE AND
        LEAF OPTICAL CABLES

        Client fiber shall be Corning LEAF(TM) (see attachment) and a portion of
        Bonneville's fiber shall be Single Mode (see attachment).

                     FIBER OPTIC PRIVATE NETWORK AGREEMENT

                                   EXHIBIT A

FIBER TESTING & PERFORMANCE CRITERIA

MFN will perform fiber testing as described below on each Leased Fiber and will
provide the documentation (hard copy and/or diskette) of results to the Carrier
at the Turnover Date. Each "span" will be defined in documentation included in
the Carrier's Turnover Date package. Acceptance of a span by Carrier will be an
acknowledgement by the Carrier that all Leased Fiber complies with all
performance criteria contained herein.

1)   POWER TESTING: This end-to-end loss measurement will be conducted for each
     Leased Fiber in the span and from both directions using an
     industry-accepted laser source and power meter. The bi-directional average
     will be used to determine the end-to-end loss of the span at each
     appropriate wavelength. This test will be conducted at both 1310 nm and
     1550 nm for Standard Single Mode Fiber; Dispersion Shifted Fiber (True
     Wave(TM), LEAF(TM), etc.) will be tested at 1550 nm only. In the event that
     a span consists of both Standard Single Mode and Dispersion Shifted fiber
     types, only 1550 nm testing will be conducted. This power testing will
     ensure fiber continuity and the absence of crossed fibers in the span.
     Power testing will only be conducted where the Leased Fiber is terminated
     by MFN in fiber distribution panels at both ends of the span.

2)   OTDR TESTING: All traces will be provided in hard copy and diskette form
     using GR 196 format. This testing will be conducted at both 1310 nm and
     1550 nm wavelengths when the Leased Fiber consists of Standard Single Mode
     Fiber, but will be done at 1550 nm only if the Leased Fiber consists of
     either Dispersion Shifted Fiber (True-Wave(TM), LEAF(TM), etc.) or a
     combination of Single Mode and Dispersion Shifted fiber types.

     OTDR testing will be conducted on a bi-directional basis for each Leased
     Fiber in each span at the appropriate wavelengths for the Leased Fiber
     described above. However, if due to length or attenuation reasons that the
     Leased Fiber span exceeds the dynamic range of an OTDR, a portion or all of
     the span may be tested on a unidirectional basis only. Alternatively, the
     Leased Fiber span may be divided into shorter testing spans, to the extent
     reasonably possible, in order to obtain bi-directional analysis. Also, in
     instances where a Carrier intends to accept Leased Fiber that is not
     terminated at one end by MFN in a fiber distribution panel (such as in a
     manhole or handhole) only unidirectional testing will be performed.

     The Turnover documentation package delivered at the Turnover Date will
     contain the actual traces that detail the testing parameters (including
     pulse width, averaging and range). The average bi-directional splice loss
     for all splices within each span will be of 0.15 dB or less while each
     connector pair (such as at a FDP) will have an average bi-directional
     connector loss for all splices within each span of 0.5 dB or less for all
     connectors within each span. (Note that the front and end connector of the
     span can only be measured uni-directionally and will also have a loss equal
     to or less than 0.5 dB). In the event that OTDR acceptance testing must be
     done on a unidirectional basis (for reasons described above), an average
     per span splice loss will be 0.30 dB.

     All traces will be provided in hard copy and diskette form using GR 196
     format. If the average bi-directional splice loss of each span exceeds 0.15
     dB (or 0.30 dB uni-directionally), MFN will provide upon the Carrier's
     request documentation of at least three attempts to reduce this value to
     below 0.15 dB (0.30 dB uni-directionally). The only exception to this will
     be in the instance of a splice between two different fiber types (Standard
     Single-mode to Dispersion Shifted, Depressed-Clad to Matched Clad, fibers
     with different mode-field diameters).

Carrier should also note that the loss and/or reflectance of the front-end
connector (as measured using a launch cord) is only an indicator of a problem
such as a defective port, bulkhead, or the like. Since a

                                       4
<PAGE>   5


different patch cord will be used by Carrier (that connects to their equipment,
for example) to mate to this connector, a different loss and/or reflectance may
occur.

                       FIBER OPTIC PRIVATE NETWORK AGREEMENT

                           GENERAL TERMS AND CONDITIONS

1.    TERM AND LEASE

1.1   MFN hereby leases to Carrier optical fiber ("Leased Fiber") on MFN's fiber
      optic cable network ("Network") and/or constructed and installed
      specifically for Carrier and the equipment and interfaces described in the
      Product Order ("Equipment") , as provided in the Product Order. The Leased
      Fiber and Equipment leased by Carrier will be referred to as the
      "Product". The lease term ("Lease Term") and other specific terms
      pertaining to the Product are set forth in the Product Order. The term
      "Party" will refer, individually, to either MFN or Carrier and the term
      "Parties" will refer to both of them. The term "Agreement" will mean and
      include the Product Order and all Exhibits thereto and these General Terms
      and Conditions.

1.2   MFN will use commercially reasonable efforts to complete installation of
      and provide Carrier with access to the Product on or about the Estimated
      Installation Completion Date specified in the Product Order at the
      Locations specified in the Product Order ("Turnover Date"). For a period
      of time not to exceed ten (10) business days after the Turnover Date (the
      "Acceptance Test Period"), Carrier will conduct such testing as it
      reasonably deems necessary to ensure that the Product conforms in all
      material respects to the material technical specifications set forth in
      the relevant Exhibits ("Specifications"), Carrier will complete such
      acceptance testing and notify MFN in writing within the Acceptance Test
      Period of any "Deficiencies" (as defined herein) in the Product, otherwise
      the Product shall be deemed to be accepted by Carrier, Deficiencies exist
      if the Product does not conform in all material respects to the relevant
      Specifications. Upon receipt of such notification from Carrier, MFN will
      promptly undertake correction of such Deficiencies and restore access to
      and use of the Product to Carrier. The "Service Date," whereupon the Lease
      Term commences, will be the earlier of (i) completion of testing and
      acceptance of Product by Carrier or (ii) expiration of the Acceptance Test
      Period. MFN shall test the Leased Fibers in accordance with the procedures
      specified in the Exhibits to verify that the Lased Fibers are installed
      and operational in accordance with the specifications described in the
      Exhibits. Fiber testing shall progress span by span along each portion of
      the Product as cable splicing progresses, so that test results may be
      reviewed in a timely manner. MFN shall provide Carrier reasonable advance
      notice of the date and time of each fiber test such that Carrier shall
      have the opportunity to have a person or persons present to observe MFN's
      fiber testing. When MFN has determined that the results of the fiber
      testing with respect to a particular span show that the Leased Fibers so
      tested are installed and operating in conformity with the applicable
      specifications set forth in the Exhibits, MFN shall promptly provide
      Carrier with a copy of such test results.

1.3   Carrier will obtain all necessary approvals for access into the Location
      buildings and for the use of any required building riser conduit or other
      required building facilities at all Locations. Unless otherwise provided
      for in the Product Order, if there is no existing and available riser
      conduit or other required facilities within such buildings then MFN will
      perform all construction and installation of such riser conduit and
      Carrier will reimburse MFN for the entire cost to construct and install
      such riser conduit plus [*] plus applicable sales or
      other taxes.

1.4   Upon the expiration of the Lease Term, or any earlier termination of this
      Agreement, Carrier will promptly remove from any property owned, leased or
      licensed by MFN all Carrier property, equipment and other materials used
      in connection with the Product within forty five (45) days from such
      expiration or termination. Carrier will complete such removal in a manner
      that does not interfere with or damage the Product or the Network. If
      Carrier fails to

2.   TERMS OF PAYMENT

2.1  Unless otherwise provided for in the Product Order, Carrier agrees to pay
     the One Time Installation Charge upon the execution of this Agreement and
     the Prepaid Lease Payment as provided in the Product Order. Carrier will
     also pay to MFN all applicable sales or other taxes other than taxes on or
     measured by MFN's income or capital, ("Applicable Taxes"), unless Carrier
     is eligible for an exemption and Carrier provides to MFN an exemption
     certificate or other documentation. Commencing on the earlier of (i) the
     Service Date for the first Location of each Ring or (ii) 180 days after
     the effective date of the product Order (unless all such delays are caused
     by or result from the act or omission of MFN), Carrier will pay the
     Prepaid Lease Payment (and the Monthly Maintenance Payment for the
     Equipment, if applicable) plus Applicable Taxes. The Prepaid Lease
     Payment, if any, will be paid as provided in the Product Order.

2.2  The Monthly Lease Payment for the Leased Fiber and, if applicable, the
     Monthly Maintenance Payment for the Equipment and any payment pursuant to
     a collocation agreement, if any, (together, the "Payment") will be
     increased (but not decreased) each year during the Lease Term by the
     percentage increase, if any, in the Consumer Price Index -- Urban Wage
     Earners and Clerical Workers (U.S. City Average, All Items, Base
     1982-1984 equals 100) (the "Index"), as published by the United States
     Department of Labor, Bureau of Labor Statistics (the "Bureau"). The Index
     for the calendar month which is four (4) months prior to the Service Date
     will be compared with the Index for the calendar month which is four (4)
     months prior to each anniversary of the Service Date during the Lease Term
     and the Payment will be increased in accordance with the percentage
     increase, if any, between such Indexes.

2.3  If Carrier fails to pay any sum when due pursuant to this Agreement, then,
     in addition to such sum, Carrier will pay interest on such unpaid sum at
     the lower of the highest legal rate of interest permitted in the State of
     New York or one and [*] per month.

3.   MAINTENANCE, RESTORATION AND REPAIR OF THE NETWORK AND PRODUCT MONITORING

3.1  MFN will provide remote monitoring of the Network and the Product to the
     extent that the Product is incorporated into the Network. MFN will use
     commercially reasonable efforts to maintain the Product in accordance
     with the Specifications (subject to reasonable wear and tear) and the
     Network in good operating condition at all times during the Lease Term.
     The foregoing maintenance will be at no additional charge to Carrier,
     except as set forth in Section 3.4 hereof.

3.2  An "Outage" will mean the complete interruption of communications on one
     or more of Carrier's Leased Fibers resulting from physical damage to, or
     severance of, or a break in, or other failure for any Product. If an Outage
     or any other material degradation of service on any Leased Fibers occurs
     Carrier will immediately notify MFN by telephone at (888) 636-2778 or
     through such other notification procedure as Parties may establish.
     Provided that MFN personnel or contractors have access to affected Carrier
     facilities immediately upon notification, MFN will respond and commence
     work within two (2) hours after the time of notification by Carrier and
     restore effective use of the Product as expeditiously as practicable, but
     in no event more than four (4) hours after receipt by MFN of Carrier's
     notification, subject to "Force Majeure" as provided in Section 11 hereof.

3.3  Except for any Outage caused by or resulting from (i) Force Majeure as set
     forth in Section 11 hereof; (ii) the act or omission of Carrier, its
     employees, agents or contractors; (iii) any of Carrier's equipment or
     facilities used in connection with the Product; or (iv) planned Outages by
     reason of Services which have been scheduled and approved in advance by
     Carrier ("Excepted Outages") in the event of an Outage, Carrier will
     receive from MFN a

    throughout this exhibit.


                                       3
<PAGE>   9
     credit ("Outage Credit") calculated at [*] of the Leased Fiber Monthly
     Lease Payment for the affected Leased Fiber strands for each [*] of Outage,
     up to a maximum of the Leased Fiber Monthly Lease Payment for [*]. Except
     in the case of a Prepaid Lease Payment or termination as provided in this
     Section 3.3, the Outage Credit will be applied against future payments
     which may become due and payable by Carrier to MFN. The Outage Credit will
     be determined by dividing the total Leased Fiber Monthly Lease Payment by
     the number of Locations and dividing this result by the number of Leased
     Fiber strands to determine the Leased Fiber Monthly Lease Payment per
     Leased Fiber Strand. This result is then multiplied by [*] and by the
     number of [*] Outage periods. For example, if the Leased Fiber Monthly
     Lease Payment for six (6) Locations is [*], the Leased Fiber Monthly Lease
     Payment for each Location would be [*], and if there were four (4) Leased
     Fiber strands for each Location, the result would be [*] per Fiber Strand.
     If the Outage affected two (2) strands at one Location for [*], the Outage
     Credit would be [*]. For purposes of determining the Outage Credit pursuant
     to this Section 3.3, if the Product Order provides for a Prepaid Lease
     Payment, then the Monthly lease payment will be determined by dividing the
     Prepaid Lease Payment by the total number of months of the Lease Term. The
     Outage Credit will be in the form of a cash payment to Carrier by MFN if
     Carrier has paid the Prepaid Lease Payment in full or if this Agreement is
     terminated by either Party as provided in Section 3.4 hereof. Outage
     Credits will not be credited or payable for any period of time during which
     MFN personnel or contractors are denied access to Carrier Locations or
     other facilities to remedy an Outage.

3.4  If an Outage occurs and continues for a period longer than fifteen (15)
     days for any reason other than "Force Majeure" as defined in this
     Agreement, then at any a time thereafter, unless and until such Outage is
     corrected, either Party can terminate this Agreement and the Product Order
     with respect to the Product subject to the Outage by written notice of
     such termination delivered to the other Party. Notwithstanding the
     foregoing, if such Outage occurs and continues by reason of a breach by a
     Party of its obligations under this Agreement, such breaching Party will
     not have any right to terminate this Agreement. The Outage Credit and
     right to terminate will be the sole and exclusive remedy of Carrier and
     liability of MFN for any Outage regardless of the cause of such Outage.

3.5  If all or part of the Product requires restoration, replacement or repair
     by reason of an act or omission of Carrier, its employees, agents or
     contractors or any of Carrier's equipment or facilities used in connection
     with the Product, such repair, replacement and/or restoration will be made
     by MFN, at Carrier's sole expense, in accordance with MFN's then current
     time and materials rates plus Applicable Taxes. In addition, Carrier will
     not receive any Outage Credit by reason of the foregoing.

3.6  MFN may assign or subcontract to any third party any or all of its
     performance obligations (including limitation maintenance) under this
     Agreement and Product Order at any time, without the consent of Carrier,
     provided that MFN will remain obligated for such performance in accordance
     with the terms of this Agreement.

3.7  MFN will have the right to inspect Carrier's use of the Product at any
     time and from time to time during normal business hours upon at least
     "twenty-four (24) hours" prior notice by MFN.

4.   USE AND OWNERSHIP OF THE PRODUCT

4.1  Carrier will not, by itself or through any agent or contractor, make any
     repair to or replacement of the Product or the Network or any other
     equipment or facilities provided by MFN in connection with the Product or
     otherwise. Carrier will not install any equipment to be used with the
     Product or use the Product in any manner which damages or interferes with
     the Product or the Network. Subject to the provisions of this Agreement,
     Carrier shall

     have full and complete control and responsibility for determining the
     equipment to be used in conjunction with the Product.

4.2  Carrier will use the Product in full compliance with all applicable
     federal, state and local laws, rules and regulations and all applicable
     franchises, rights of way, leases, licenses, contracts and other
     obligations to third parties with respect to the Network or Product.
     Carrier will obtain and maintain in effect during the Lease term all
     rights, leases, licenses, permits and governmental or non-governmental
     approvals necessary for use of the Product by Carrier and its customers.

4.3  Carrier acknowledges and agrees that the Product is provided for use (1)
     exclusively by Carrier and/or affiliated entities which control or are
     controlled by or commonly controlled with Carrier ("Affiliates") which are
     named in the Product Order (if so named, then the term "Carrier" as used in
     this Agreement will include any such Affiliates of Carrier), (2) customers
     of Carrier and (3) in either case only in the ordinary course of business
     of Carrier. For purposes of this Agreement, the ordinary course of
     Carrier's business shall not include the sale, leasing or granting of any
     rights of use in "dark fiber", as such term is commonly understood in the
     telecommunications industry. Carrier will not under any circumstances (a)
     permit or provide access to or use of the Product, in whole or part, to any
     third party (other than a customer of Carrier in the ordinary course of
     business of Carrier), pursuant to (by way of example and not in limitation)
     sublease, license, sublicense or resale, or any other right to use, or (b)
     share or otherwise utilize in conjunction with a third party (including
     without limitation in any joint venture or as part of any outsourcing
     activity) any of the Product. Any breach of this Section 4.3 will be deemed
     to be a material breach of this Agreement and in the event of such material
     breach MFN will have the right to immediately terminate this Agreement, any
     applicable Product Orders and Carrier's access to the Network, in addition
     to any and all rights and remedies.

4.4  MFN retains all right, title and interest in and to the Product and the
     Network to the points within the locations specified in the Product Order
     at which MFN's facilities end and Carrier's facilities begin, subject only
     to the grant of access and use provided to Carrier pursuant to this
     Agreement. MFN agrees to use commercially reasonable efforts to obtain a
     non-disturbance agreement from any third party in favor of which MFN in its
     discretion shall have granted after the date hereof a security interest or
     lien on all or part of the Product.

4.5  MFN reserves the right to utilize unused external building access and space
     within the building conduit(s) occupied by the Product at the locations and
     otherwise, provided that such use does not interfere with or hinder
     Carrier's use of its Product as permitted hereunder.

5.   AUTHORIZATIONS; RELOCATION; CONDEMNATION

5.1  "Authorization(s)" will mean all material and applicable governmental or
     non-governmental licenses, easements, rights of way, conduit, pole
     attachment and any other facilities or property rights, licenses,
     contracts, franchises, approvals, permits, orders, consents, and all other
     rights required for MFN to operate and maintain the Network or provide the
     Product to Carrier pursuant to this Agreement.

5.2  MFN will use commercially reasonable efforts to have or obtain by the
     Service Date, all Authorizations and to maintain or renew all such
     Authorizations through the Initial Term and to replace such Authorizations
     with reasonably suitable replacement Authorizations if any expire or are
     terminated or discontinued during the Initial Term. If any Authorizations
     are modified, terminated or discontinued and not replaced, and the loss of
     such Authorizations threatens to cause or does cause material financial
     harm to MFN, or prevents or materially interferes with MFN's control,
     possession and/or use of the Network or ability to lease the Product or
     materially and adversely affects the use by Carrier of the Product, then
     MFN will


                                       5
<PAGE>   11
      at its option either (i) provide Carrier with comparable Product or fiber
      optic capacity on portions of MFN's then existing Network (and/or other
      MFN Networks, including networks belonging to or controlled by MFN
      Affiliates) or on networks of third parties, or (ii) terminate this
      Agreement with respect to the effected Product and rebate to Carrier the
      pro rata portion of all Prepaid Lease Payments allocable to the terminated
      Product and amortized over the remainder of the Lease Term. The foregoing
      will be MFN's sole and exclusive liability and Carrier's sole and
      exclusive remedy with respect to the foregoing.

5.3   If MFN receives notice of any request, intent or plan by any governmental
      or non-governmental third party, to relocate any material part of the
      Product or any material segment of MFN's Network used in the provision of
      the Product, MFN will notify Carrier of such request, intent or plan. If
      MFN is required by any such third party to relocate any segment of MFN's
      network used in providing the Product, MFN will give Carrier at least
      sixty (60) days (or such lesser period of notice that MFN may have
      received) prior written notice of any such relocation ("Relocation
      Notice"). Together with the Relocation Notice, MFN will provide an
      estimate of the cost of such relocation. MFN will relocate the Leased
      Fibers, and, to the extent MFN is not reimbursed for the cost of such
      relocation by a third party, governmental entity or otherwise, Carrier
      will pay its pro rata share of the costs associated with the relocation of
      the Product; except, however, to the extent that such relocation is the
      direct result of any negligent or willful act or omission of MFN, MFN will
      use its commercially reasonable efforts to secure an agreement for
      reimbursement from any third party, governmental entity or otherwise,
      requiring any relocation of the Network and the Product.

5.4   If any portion of the Network or the Product and/or the Authorizations in
      or upon which the Product has been installed, become the subject of a
      condemnation proceeding which is not dismissed within one hundred eighty
      (180) days after the date of filing of such proceeding and which could
      reasonably be expected to result in a taking by any governmental agency or
      other party having the power of eminent domain for public purpose or use,
      both Parties will be entitled, to the extent permitted under applicable
      law, to participate in any condemnation proceedings for compensation by
      either joint or separate awards for the economic value of their respective
      interests in the Leased Fibers that are subject to such condemnation
      proceeding.

5.5   MFN shall be responsible for and shall timely pay any and all fees, taxes,
      levies, charges or withholdings of any nature, together with any
      penalties, fines, or interest thereon relating to the Authorizations.

6.    WARRANTIES

6.1   MFN warrants to Carrier that upon the Service Date the Product will
      operate in accordance with the specifications related thereto.

            EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, MFN
            DISCLAIMS ALL WARRANTIES WHETHER EXPRESS OR IMPLIED INCLUDING ANY
            AND ALL WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
            PURPOSE WITH RESPECT TO THE (i) NETWORK OR PRODUCT, (ii) THE LEASE
            GRANTED PURSUANT HERETO, (iii) MAINTENANCE SERVICES (iv)
            CONSTRUCTION AND INSTALLATION SERVICES, IF ANY, AND (v) ANY OTHER
            SERVICES(S) (HEREINAFTER (iii) THROUGH (v) WILL COLLECTIVELY BE
            REFERRED TO AS "SERVICES") PROVIDED BY OR ON BEHALF OF MFN
            HEREUNDER.

7.    LIABILITY/INDEMNIFICATION


                                      -6-
<PAGE>   12
  7.1  Except for the gross negligence or willful misconduct of a Party
       hereto and except where a specific remedy is provided in this Agreement,
       the liability of each Party to the other Party for damages will be
       limited to [*]. In no event will either Party be liable to the other
       Party for any incidental, indirect, special, consequential, exemplary, or
       punitive damages arising out of or relating to this Agreement, the lease
       granted hereunder, the Network, Product or Services provided hereunder,
       including damages based on loss of revenues, profits or lost business
       opportunities, regardless of whether the respective Party had been
       advised of or could have foreseen the possibility of such damages.

  7.2  Each Party agrees to indemnify, defend and hold the other, its officers,
       directors, employees, agents and contractors harmless from and against
       all loss, damage, liability, cost and expense (including reasonable
       attorney's fees and expenses) by reason of any claims or actions by third
       parties for (i) bodily injury, including death, (ii) damage, loss or
       destruction of any real or tangible personal property (including without
       limitation the Network and Product) which third party claims arise out of
       or relate or (a) any Product or Services provided by or on behalf of MFN
       hereunder, (b) a Party's performance of or failure to perform any term,
       condition or obligation under this Agreement, (c) any act or omission of
       a Party's directors, agents, employees, contractors, representatives or
       invitees, or (d) Carrier's or its customer's use of the Product and
       conduct of their respective businesses including without limitation the
       content of any video, voice or data carried by Carrier or its customers
       on the Product or Network.

  7.3  Except as otherwise set forth in this Agreement, nothing contained herein
       will operate as a limitation on the right of either Party to bring an
       action for damages against any third party based on any act or omission
       of such third party as such act or omission may affect the construction,
       operation, or use of the Product. Each Party agrees to execute such
       documents and provide such commercially reasonable assistance, at the
       claiming Party's sole expense, as may be reasonably necessary to enable
       the claiming Party to pursue any such action against such third party.

  8.   CONFIDENTIALITY
       --------------

  8.1  The Parties acknowledge and agree that this Agreement and the information
       each Party has provided or will provide in connection with this
       Agreement or that the other Party learns or obtains from a source other
       than public domain or from a source (including a Party) not in violation
       of any obligation of confidentiality, are and will be confidential
       and proprietary to the Party providing such information (the "Providing
       Party"). The Party in receipt of or learning or obtaining the
       confidential information (the "Receiving Party") agrees not to
       distribute, use or disclose to any third party the confidential
       information of the Providing Party.

  8.2  Except as may be required by applicable legal requirements in the
       course of defending or prosecuting a legal, insurance or other claim
       or as required by applicable law, rule or regulation, Receiving Party
       will restrict dissemination of confidential information to only those
       persons who must have access to such confidential information in order
       to perform their respective rights or obligations hereunder. The
       Receiving Party will promptly notify the Disclosing Party of any such
       required disclosure to enable the Disclosing Party to seek protective
       relief therefrom and shall cooperate as the Disclosing Party may
       request in connection therewith.

  8.3  Carrier may disclose the identity of MFN as a supplier of Carrier, and
       MFN may disclose the identity of Carrier as customer of MFN, each with
       the prior written consent from the others which consent will not be
       unreasonably withheld or delayed; provided; that no such disclosure
       shall imply any endorsement of the disclosed Party or contain any
       misleading reference to the nature of the relationship between the
       Parties.

8.4  Each Party acknowledges and agrees that the information of the Disclosing
     Party described in this Section 8 constitutes valuable property of the
     Disclosing Party and that Disclosing Party will suffer irreparable injury
     not compensable by money damages for which the Disclosing Party will not
     have an adequate remedy at law in the event of a breach by the Receiving
     Party of the provisions for this Section 8 and therefore the Disclosing
     Party shall be entitled to injunctive relief to prevent or curtail any such
     breach, threatened or actual. The foregoing shall be without prejudice to
     or limitation on any other rights a Party may have under this Agreement, at
     law or in equity.

term upon the terms and conditions of this Agreement, except for the length of
such renewal term and the Installation and Lease Fee payments, which the Parties
will negotiate in good fifth following Carrier's written request for renewal
delivered to MFN no earlier than one year before the scheduled expiration date
of the initial term and no later that ninety (90) days before such expiration
date.

11.  TERMINATION/FORCE MAJEURE

     11.1 If any of the following events of default occur, the non-breaching
          Party (if MFN) will have the right to deny access by Carrier to the
          Product or Network and (if either Party) to terminate this Agreement
          by written notice following the expiration of any periods of time
          included in the following, such termination to be effective in the on
          the date set forth in the written notice of termination:

          11.1 (a)  If Carrier terminates any Product Order at any time before
                    the expiration of the Lease Term (whether before or after
                    the Turnover Date) or falls to make any payment hereunder
                    within five (5) days or receipt of written notice of late
                    payment from MFN, MFN will have the right to terminate this
                    Agreement and deny access by Carrier to the Product or
                    Network immediately without further notice to Carrier.


          11.1 (b)  If a Party breaches any material term or condition of this
                    Agreement and such breach remains uncured thirty (30) days
                    after delivery to the breaching Party of written notice of
                    such breach, unless the breach is of a nature or involves
                    circumstances requiring more than thirty (30) days to cure,
                    or if MFN's failure is failure to complete construction,
                    installation, and successful fiber acceptance and testing by
                    the Estimated Installation Completion Date, the time period
                    may be extended for such time as will be reasonably
                    required, provided the defaulting party proceeds diligently
                    to cure the breach.

          11.1 (c)  A Party applies for or consents to the appointment of a
                    receiver, trustee or similar officer for it or any
                    substantial part of its property or assets, or any such
                    appointment is made without such application or consent by
                    such Party and remains undischarged for a period of sixty
                    (60) days; or




                                       8





<PAGE>   14
          11.1 (d)  A Party consents to the institution of a petition,
                    application, answer, consent, default of otherwise of any
                    bankruptcy, insolvency or reorganization and any such
                    proceeding as instituted against such Party remains
                    undischarged for a period of sixty (60) days.

     11.2 In the event of termination of the Product Order by MFN pursuant to
          Section 11.1 hereof or by Carrier after execution of the Product Order
          or before the end of the Lease Term (other than by Carrier for cause
          as provided in this Section 11), MFN will be entitled to receive, and
          Carrier will immediately pay, the early termination charge ("Early
          Termination Charge") set forth in the Product Order, and to offset any
          remaining portion of the Prepaid Lease Payment against any sums
          otherwise due and payable by Carrier to MFN pursuant to this
          Agreement.

     11.3 If any Authorization is modified, terminated or discontinued and not
          replaced as provided in Section 5.2 of these General Terms and
          Conditions, and MFN has not notified Carrier in writing within sixty
          (60) days after the occurrence of such modification, termination or
          discontinuance that MFN will provide additional or substitute Product
          or capacity as provided in Section 5.2, then and thereafter either
          party has the right, exercisable in its sole discretion, to terminate
          the Product Order with respect to the affected Product upon thirty
          (30) days prior written notice (or such other notice as is
          practicable under the circumstances) without liability whatsoever by
          either Party to the other Party or any party claiming by, through or
          under such other Party other than the return to Carrier, of the
          unamortized portion of any Prepaid Lease Payment as of the date of
          such termination as provided in Section 5.2.

     11.4 Neither Party will be in breach of this Agreement resulting from delay
          or prevention of performance of such Party which is caused by any act
          attributable to an occurrence or an event of "Fore Majeure" as defined
          herein. Neither party will, however, be relieved of liability for
          failure of performance due to a claimed Force Majeure hereunder if
          such failure is due to causes arising out of its own negligence or to
          removable or remedial causes that it fails to remove or remedy using
          commercially reasonable efforts and within a reasonable period of
          time.

     11.5 The term "Force Majeure" will mean any cause beyond the control of
          Carrier (or MFN, as applicable) which, by the exercise of due
          foresight, Carrier (or MFN) could not reasonably have been expected to
          avoid, and which by the exercise of reasonable diligence, Carrier (or
          MFN) will be unable to overcome, including but not limited to action
          by governmental authority including without limitation moratorium on
          any activities related to the Agreement, third party labor dispute,
          flood, earthquake, fire, lightning, epidemic, war, riot, civil
          disturbance, sabotage and the like. The party affected by an event of
          Force Majeure (the "Affected Party") will notify the other party (the
          "Other Party") promptly of any occurrence or condition which, in the
          Affected Party's reasonable opinion, warrants an extension of time.
          Such notice will specify in detail the anticipated length of delay,
          the cause of the delay and a timetable by which any remedial measures
          will be implemented.

12.  ASSIGNMENT; SUCCESSION

     12.1 Carrier will not assign any right nor delegate any duty under this
Agreement, in whole or in part, whether by operation of law or otherwise,
without the prior written consent of MFN, such consent not to be unreasonably
withheld or delayed. Carrier shall have the right, without MFN' consent, to
assign this Agreement to (i) any entity which controls, is controlled by or is
under common control with Carrier or (ii) any entity into which Carrier may be
merged or consolidated or which purchases all or substantially all of the stock
or assets of Carrier; provided that the assignee or transferee in any such
circumstance shall continue to be subject to all of the provisions of this
Agreement, including, without limitation, the provisions of this section; and
provided further that in any of the circumstances


                                       9
<PAGE>   15

     described in clauses (i) and (ii) all of the payment obligations of
     Carrier hereunder for the remainder of the Lease Term shall be paid in
     full as a condition to such transfer or assignment; and provided further
     that Carrier shall give MFN written notice identifying the assignee or
     transferee. Upon any permitted assignment (or delegation) hereunder,
     Carrier will remain jointly and severally responsible for the performance
     under this Agreement unless released in writing by MFN. Any permitted
     assignee will expressly assume all liabilities hereunder prior to the
     effectiveness of such assignment. Any attempted assignment or delegation
     without such consent will be null and void and may be deemed by MFN, in
     its sole discretion, to constitute a material breach of this Agreement.

12.2 The Agreement and Product Order will be binding upon and inure to the
     benefit of the Parties hereto and their respective successors and
     permitted assigns.

13.  GOVERNING LAW

13.1 THIS AGREEMENT WILL BE INTERPRETED AND CONSTRUED IN ACCORDANCE WITH THE
     INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ITS
     PRINCIPLES OF CONFLICTS OF LAWS.

14.  SURVIVAL

The Parties' respective representation, warranties, and covenants, together
with obligations of indemnification, confidentiality and limitations on
liability will survive the expiration, termination or rescission of this
Agreement and continue in full force and effect.

15.  ENTIRE AGREEMENT

This Agreement, Product Order, Exhibits and all addenda attached hereto
constitute the entire agreement between the parties hereto with respect to the
subject matter hereof and supersede any and all prior negotiations,
understandings, and agreement with respect hereto, whether oral or written.

16.  REMEDIES CUMULATIVE

Except as otherwise expressly provided, the rights and remedies set forth in
this Agreement will be in addition to, and cumulative of, all other rights and
remedies at law or in equity.

17.  REPRESENTATIONS, WARRANTIES AND COVENANTS

corporation, limited liability company, partnership, or other legal entity,
duly organized, validly existing and in good standing under the laws of the
state of its organization, (b) it has all requisite power and authority to
enter into, and perform its obligations under this Agreement and Product Order
and (c) this Agreement, when executed, will become the legal, valid and binding
obligation of such Party.

18.  CONSTRUCTION OF NETWORK

18.1 MFN shall, at MFN's sole cost and expense, be responsible for and shall
effect the design, engineering, installation and construction of those portions
of the Network nor already constructed as of the date hereof in accordance with
the Specifications set forth in the Exhibits. All Leased Fiber shall meet or
exceed the applicable fiber specifications set forth in the Exhibits.

Carter shall have the right, upon written request, to inspect the construction,
installation, splicing and testing of the Product during the course and at the
time of the relevant design, construction and installation period as may be

right to connect, at Carrier's sole cost and expense, its telecommunications
Network with the Product at various network access points on the Network as may
be requested by Carrier and agreed to by MFN. The specific locations of each
such connections shall be as mutually reasonably agreed upon by the parties.
Any such connection will be performed by MFN, at Carrier's sole cost and
expense, in accordance with MFN's applicable specifications and operating
procedures.

20.2  Carrier shall pay MFN's cost for each such connection within thirty (30)
days of the date of Carrier's receipt of MFN's invoice therefor. In order to

approved to do business in the state where the construction will be performed:

      (a)   not less than $5,000,000 combined single-limit liability insurance,
            on an occurrence basis, for personal injury and property damage,
            including, without limitation, injury or damage arising from the
            operation of vehicles or equipment and liability for completed
            operations;

      (b)   workers' compensation insurance in amounts required by applicable

            agreements with railroads or other third parties.


21.2  MFN shall require its subcontractors who are engaged in connection with
the construction of the Network to maintain insurance in the types and amounts
as would be obtained by a prudent person to provide adequate protection against
loss. In all circumstances, MFN shall require its subcontractors to carry a
minimum of $1,000,000 in commercial general liability.

22.   DISPUTE RESOLUTION

22.1  Except as provided in Article 11, if the parties are unable to resolve
any disagreement or dispute arising under or related to this Agreement,
including without limitation, the failure to agree upon any item requiring a
mutual agreement of the parties hereunder, they shall resolve the disagreement
or dispute by arbitration as prescribed in this Section. The Federal
Arbitration Act, 9 U.S.C. Sections 1-15, not state law, shall govern the
arbitrability of all claims.



                                       11
<PAGE>   17
22.2 Three arbitrators engaged in the practice of law who are knowledgeable
     about the subject matter of this Agreement shall conduct the arbitration
     under the then current rules of the American Arbitration Association (the
     "AAA"). The arbitrator shall be selected in accordance with AAA procedures
     from a list of qualified people maintained by the AAA.

22.3 The arbitration shall be conducted in the AAA office in Washington, D.C.,
     and all expedited procedures prescribed by the AAA rules shall apply.

22.4 There shall be no discovery other than the exchange of information which is
     provided to the arbitrator by the parties. The arbitrator shall have
     authority only to award compensatory damages and shall not have authority
     to award punitive damages, other noncompensatory damages or any other form
     of relief; the parties hereby waive all rights to any claims for relief
     other than compensatory damages. The arbitrators' fees and other costs of
     the arbitration shall be borne by the party against whom the award is
     rendered, except as the arbitration panel may otherwise provide in its
     written opinion.

22.5 If any party files a judicial or administrative action asserting claims
