         The Routing Point is employed to calculate mileage measurements for the
         distance-sensitive transport element charges of Switched Access
         services. The Routing Point need not be the same as the Rating Point,
         nor must it be located within the Rate Center area, but must be in the
         same LATA as the NPA-NXX.

 1.42    "Switched Access" service means an offering of access to services or
         facilities for the purpose of the origination or termination of traffic

4.       INTERCONNECTION PURSUANT TO SECTION 251(c)(2)(A),(B),(C); 47 CFR

         51.305(a)(1)

4.1      Scope

         This Section describes the physical architecture for Interconnection of
         the Parties' facilities and equipment for the transmission and routing
         of Telephone Exchange Service traffic and Switched Access traffic
         pursuant to Section 251(c)(2) of the Act. Such Interconnections shall
         be equal in quality to that provided by the Parties to themselves or to
         any subsidiary, affiliate or Third Party. Appendix ITR attached hereto
         and incorporated by reference prescribes the specific trunk groups (and
         traffic routing parameters) which will be configured over the physical
         connections described in this Section 4 to provide the facilities for
         the transmission and routing of Telephone Exchange Service traffic (as
         described in Section 5), Switched Access traffic (as described in
         Section 6) and BLV/BLV/I traffic (as described in Section 7.2).

4.2      Interconnection Coverage Section 251(c)(2)(B) and (C). 47 CFR Section
   ---------------------------------------------------------------------------
51.305(a)(2)

The Parties will establish Local Interconnection Trunks to exchange Local and
IntraLATA Toll traffic. All Local Interconnection Trunk Groups established
directly with the other Party's network, including facilities and Points of
Interconnection ("POIs"), will conform with this Section of this Agreement. All
traffic exchanged over Local Interconnection Trunk Groups will be treated as
CLEC traffic and subject to the terms and conditions of this Agreement. Neither
Party shall terminate Switched Access traffic over Local Interconnection Trunks.
Separate two-way Meet Point trunks will be established for the joint
provisioning of Switched Access traffic. Local Interconnection will be provided
via two-way Minks unless both Parties agree to implement one-way trunks on a
case-by-case basis.

4.2. 1. CLEC shall interconnect with NEVADA's facilities as follows:

(a)      Each Party will establish a Local Interconnection Trunk Group with

         each Access Tandem in the LATA(s) in which it originates or terminates
         Local and/or Toll traffic with the other Party. Parties may not route
         Local Interconnection traffic to an Access Tandem destined for an NXX
         that subtends another tandem. The Parties agree that direct trunking to
         an End Office from either Party's End Office or Access Tandem is
         permitted under the terms of this section.
<PAGE>

CLEC will interconnect with any NEVADA Access Tandems in each of the LATA(s) in
which it originates traffic and interconnects with NEVADA.

(b)      In addition to the tandem interconnection described above, either

         Party may establish End Office-to-End Office or End Office-to-tandem or
         tandem-to-tandem trunk groups. In the case of host remote End Offices,
         such interconnection shall occur at the location of the host or remote,
         at the option of the Party deploying the host-remote End Office.

     4.2.2. NEVADA shall interconnect with CLEC's facilities under terms and
          conditions no less favorable than those identified in Section 4.2. 1,
          above.

4.3      Methods for Interconnection

Where the Parties interconnect, for the purpose of exchanging traffic between
networks, the Parties may use the following interconnection methods for each
Tandem and End Office identified in Appendix DCO making use of facilities they
own or lease from a third party or NEVADA:

(a)      Physical Collocation

          As set forth in Appendix PHYSICAL COLLOCATION.

          (b) Virtual Collocation

          As set forth in Appendix NIM.

(c)      Leased Facility Interconnection ("LFI")
   ---------------------------------------------

         Where facilities exist, either Party may lease facilities from the
other Party as defined in Section 6 of Appendix NIM.

(d)      Fiber Meet

         The Parties agree to establish technical interface specifications for
         Fiber Meet arrangements that permit the successful interconnection and
         completion of traffic routed over the facilities that interconnect at
         the Fiber Meet. The technical specifications will be designed so that
         each Party may, as far as is technically feasible, independently select
         the transmission, multiplexing, and fiber terminating equipment to be
         used on its side of the Fiber Meet.

(e)      Other Interconnection Methods

     Other interconnection methods, as negotiated by the Parties, which
          interconnect CLEC's and NEVADA's networks for the transmission and
<PAGE>

routing of telephone exchange traffic, Switched Access traffic, or both; at any
technically feasible point within NEVADA's network including:

the line-side of a local switch;

(ii)     the trunk-side of a local switch;

(iii)    the trunk interconnection points for a tandem switch;

(iv)     central office cross-connect points;

(v)      out-of-band signaling transfer points necessary to exchange traffic

         at these points and access call related databases; and

(vi)     the points of access to unbundled Network Elements;

                  shall be at a level of quality that is equal to that which
                  NEVADA provides itself, a subsidiary, an affiliate, or any
                  other party.

4.4      Physical Architecture

Using one or more of the Interconnection Methods described in Section 4.3 above,
the Parties will agree on a physical architecture plan. This plan will be
documented within Appendix DCO. CLEC and NEVADA agree to interconnect their
networks through existing and/or new facilities between CLEC End Offices and/or
Access Tandem Switches and the corresponding NEVADA End Office and/or Access
Tandems set forth in Appendix DCO. The Parties will establish logical trunk
groups referencing the appropriate CLEC Central Office or Routing Point and
NEVADA Central Office. In addition, where necessary, and as mutually agreed to,
the Parties will define facilities between their networks to permit trunk
group(s) to be established between the points listed in Appendix DCO.

Nothing in the foregoing restricts either Party from ordering and establishing
CLEC/NEVADA Local Interconnection Trunk Groups in addition to the initial
combinations described above. Amendment to the Appendix DCO may be made by
either Party, upon thirty (30) days written notice and acceptance by the other
Party. Acceptance will not be unreasonably withheld. Such amendments may be made
without the need to renegotiate the terms of the rest of this Agreement;
however, such amendments will be effective upon filing with and approval by the
Commission.

     4.4.1 The Parties will mutually agree on the appropriate sizing for
          facilities based on the standards set forth below and in Appendix NIM.
          The
<PAGE>

capacity of interconnection facilities provided by each Party will be based on
mutual forecasts and sound engineering practice, as mutually agreed to by the
Parties during planning and forecasting meetings. The interconnection facilities
provided by each Party shall be formatted using either Alternate Mark Inversion
Line Code or Superframe Format Framing. DS-3 facilities will be optioned for
C-bit Parity.

4.4.1.1     When interconnecting at NEVADA's tandems, the Parties agree to
            optionally establish Bipolar 8 Zero Substitution Extended Super
            Frame ("B8ZS ESF") two-way trunks, where technically feasible, for
            the sole purpose of transmitting 64K CCC data calls. In no case will
            these trunks be used for calls for which the User Service
            Information parameter (also referred to as "Bearer Capability") is
            set for "speech". Where additional equipment is required, such
            equipment would be obtained, engineered, and installed on the same
            basis and with the same intervals as any similar growth job for
            IXC's, CLEC's, or NEVADA's internal customer demand for 64K CCC
            trunks.

         4.4.1.2    When interconnecting at NEVADA's digital End Offices, the
                    Parties have a preference for use of B8ZS ESF two-way trunks
                    for all traffic between their networks. Where available,
                    such trunk equipment will be used for these Local
                    Interconnection Trunk Groups. Where AMI trunks are used,
                    either Party may request upgrade to B8ZS ESF when such
                    equipment is available.

4.4.2    Mid-Point Meet

                  Using the Mid-Point Meet architecture, the Parties will agree
                  upon a Point of Interconnection ("POI"). The POI functions as
                  a demarcation point for each Party. Each Party is responsible
                  to transport all trunking to its side of the POI utilizing any
                  method of interconnection described in Section 4.3 above. Each
                  Party is responsible for the appropriate sizing, operation,
                  and maintenance of the transport facility and trunking to the
                  POI.

4.5      Single POI Model

Unless otherwise agreed by the Parties, for each interconnection between the
Parties for the exchange of Local, IntraLATA Toll, and Meet Point traffic, the
Parties agree that there will be a single Point of Interconnection (at NEVADA's
or another carrier's wire center located in the geographic area where NEVADA
operates as an independent LEC) between any two switching entities.
<PAGE>

4.6      Additional Interconnection

If CLEC decides to offer Telephone Exchange Services in any LATA in which NEVADA
also offers Telephone Exchange Services, CLEC shall provide written notice to
NEVADA of the need to establish Interconnection in such LATA pursuant to Section
4.4 of this Agreement.

4.7      Responsibilities of the Parties

4.7.1    CLEC and NEVADA shall work cooperatively to install and maintain a
         reliable network. CLEC and NEVADA shall exchange appropriate
         information (e.g., maintenance contact numbers, network information,
         information required to comply with law enforcement and other security
         agencies of the Government and such other information as the Parties
         shall mutually agree) to achieve this desired reliability.

4.7.2    CLEC and NEVADA agree to exchange such reports and/or data as provided
         in this Agreement to facilitate the proper billing of traffic. Either
         Party may request an audit of such usage reports on no fewer than ten
         (10) business days written notice and any audit shall be accomplished
         during normal business hours at the office of the Party being audited
         which shall be Stockton, California for CLEC and Reno, Nevada for
         NEVADA). Such audit must be performed by a mutually agreed-to
         independent auditor paid for by the Party requesting the audit and may
         include review of the data described above. Such audits shall be
         requested within six (6) months of having received the PLU factor and
         usage reports from the other Party, and may not be requested more than
         twice per year.

4.7.3    CLEC and NEVADA will review engineering requirements on a semi-annual
         basis and establish forecasts for trunk and facilities utilization
         provided under this Agreement. New wank groups will be implemented as
         dictated by engineering requirements of either NEVADA or CLEC.

4.7.4    CLEC and NEVADA shall share responsibility for all Control Office
         functions for Local Interconnection Trunks and Trunk Groups, and both
         Parties shall share the overall coordination, installation, and
         maintenance responsibilities for these trunks, and trunk groups.

4.7.5    CLEC is responsible for all Control Office functions for the Meet Point
         Trunks and Trunk Groups, and shall be responsible for the overall
         coordination, installation, and maintenance responsibilities for these
         trunks and trunk groups.
<PAGE>

4.7.6 CLEC and NEVADA shall:

         (a)      provide trained personnel with adequate and compatible test
  - equipment to work with each other's technicians;

(b)      notify each other when there is any change affecting the service

         requested, including the due date;

(c)      coordinate and schedule testing activities of their own personnel,

         and others as applicable, to ensure its interconnection trunks/trunk
         groups are installed per the interconnection order, meet agreed upon
         acceptance test requirements, and are placed in service by the due
         date;

(d)      perform sectionalization to determine if a trouble is located in its

        facility or its portion of the interconnection trunks prior to referring
        the trouble to each other;

(e)      advise each other's Control Office if there is an equipment failure

         that may affect the interconnection trunks;

(f)      provide each other with a trouble reporting number that is readily

          accessible and available 24 hours per day/7 days a week;

(g)      provide to each other test-line numbers and access to test lines,

          including a test-line number that returns answer supervision in
          each NPA-NXX opened by a Party;

(h)      provide their respective billing contact numbers to one another on a

         reciprocal basis; and

(i)      will conduct cooperative testing for the proper recording of AMA

         records in each carrier switch(es) before establishing service.

4.7.7    Within ninety (90) days of the due date of the initial installation of
         local interconnection trunks, CLEC will provide to NEVADA CLEC's
         references or internal standards governing each topic in Appendix
         BILATERAL.

5.       TRANSMISSION AND ROUTING OF TELEPHONE EXCHANGE SERVICE

         TRAFFIC PURSUANT TO SECTION 251(c)(2)(D); 252(d)(1) and (2); 47 CFR
         Section
         51.305(al(5)

5.1      Scope of Traffic

This Section 5 prescribes traffic routing parameters for Local Interconnection
Trunk Group(s) the Parties shall establish over the Interconnections specified
in Section 4.

 5.1.1   Either Party may opt at any time to terminate, i.e., overflow, to the
         other Party some or all Local Exchange Traffic and intraLATA Toll
         traffic originating on its network, together with Switched Access
         traffic, via Feature Group D or Feature Group B Switched Access
         Services. Either Party may otherwise purchase these Switched Access
         Services from the other Party subject to the rates, terms and
         conditions specified in its standard intrastate access tariffs,
         including any usage-sensitive rates for the Local Exchange or intraLATA
         Toll traffic terminated over the Switched Access service.

 5.1.2   Each Party shall deliver to the other Party over the Local
         Interconnection Trunk Group(s) only such traffic which is destined for
         those publicly dialable NPA-NXX codes served by End Offices that
         directly subtend the Access Tandem or to those Wireless Service
         Providers that directly subtend the Access Tandem.

 5.1.3   Unless otherwise agreed to, each Party shall deliver all traffic
         destined to terminate at either Party's End Office or tandem in
         accordance with the serving arrangements defined in the LERG.

 5.1.4   Where the Parties deliver over the Local Interconnection Trunk Group(s)
         miscellaneous calls (e.g., time, weather, NPA-555, Mass Calling Codes)
         destined for each other, they shall deliver such traffic in accordance
         with the serving arrangements defined in the LERG.

5.1.5    N1 1 codes (e.g., 611, 811, & 911) shall not be sent between CLEC's and

          NEVADA's network over the Local Interconnection Trunk Group(s).

 5.1.6   For purposes of compensation under this Agreement, the
         telecommunications traffic traded between CLEC and NEVADA will be
         classified as either Local Traffic, Transit Traffic, IntraLATA
         Interexchange Traffic, interLATA Interexchange Traffic, or FGA Traffic.
         The Parties agree that, notwithstanding the classification of traffic
         under
<PAGE>

         this Agreement, either Party is free to define its own "local" calling
         area(s) for purposes of its provision of Telecommunications Services to
         its End Users.

 5.1.7   Reciprocal compensation should be paid by Nevada Bell to Pac-West for
         traffic originated by a Nevada Bell customer and terminated to any
         customer, including an Internet Service Provider ("ISP"), obtaining
         local access from Pac-West when those customers are located within the
         same Nevada Bell local calling area. Similarly, reciprocal compensation
         should be paid by Pac-West to Nevada Bell for traffic originated by a
         Pac-West customer and terminated to any customer, including an ISP,
         obtaining local access from Nevada Bell when those customers are
         located within the same Nevada Bell local calling area. [NPUC Docket
         No. 99-1007, Order Adopting Revised Arbitration Decision, April 12,
         1999]

5.1.8    Calls originated by one Party's End User and terminated to the other
         Party's End User will be classified as "Local Traffic" for purposes of
         intercompany compensation, if;

(a)      the call originates and terminates in the same NEVADA exchange

         area; or

(b)      originates and terminates within different NEVADA Exchanges

         that share a common local calling area, e.g., Extended Area Dialing
         ("EAD").

 5.1.9   NEVADA shall deliver all traffic destined to terminate at CLEC's End
         Office in accordance with the serving arrangements defined in the LERG,
         except NEVADA will not deliver calls destined to CLEC End Office(s) via
         another LEC's or CLECs tandem.

5.1.10   NEVADA shall terminate traffic from third-party LECs, CLECs, or
         Wireless Service Providers delivered to NEVADA's network through CLEC's
         tandem. Prior to the routing of such traffic, the Parties agree to
         negotiate the issues of network capacity and forecasting caused by such
         termination. The Parties shall conduct such negotiations in good faith
         and shall not unreasonably withhold consent to the routing of such
         traffic.

 5.1.11  NEVADA shall complete traffic delivered from CLEC destined to
         thirdparty LECs, CLECs or WSPs in the LATA, when these third parties
         subtend NEVADA's tandem(s). NEVADA shall have no responsibility to
         ensure that any third-party LEC, CLEC or WSP will accept such traffic.
<PAGE>

5.2      Responsibilities of the Parties

5.2.1 Each Party to this Agreement will be responsible for the accuracy and
  quality of its data as submitted to the respective Parties involved.

5.2.2    Each Party will include in the information transmitted to the other for
         each call being terminated on the other's network, where available, the
         originating Calling Party Number ("CPN").

5.2.3    If the percentage of calls passed with CPN is greater than ninety
         percent (90%), all calls exchanged without CPN information will be
         billed as either Local Traffic or IntraLATA Toll Traffic in direct
         proportion to the minutes of use ("MOU") of calls exchanged with CPN
         information. If the percentage of calls passed with CPN is less than
         ninety percent (90%), all calls passed without CPN will be billed as
         Switched Access.

5.2.4    For intraLATA Toll Free Service calls where such service is provided by
         one of the Parties, the compensation shall be charged by the Party
         originating the call, rather than the Party terminating the call. This
         includes originating charges as well as a Basic Toll Free Access Query
         charge as specified in Appendix PRICING or CLECs local exchange tariff.

5.2.5    Each Party will calculate terminating interconnection minutes of use
         based on standard Automatic Message Accounting ("AMA") recordings made
         within each Party's network. These recordings are the basis for each
         Party to generate bills to the other Party.

5.2.6    Measurement of minutes of use over Local Interconnection Trunk Groups
         shall be in actual conversation seconds. The total conversation seconds
         over each individual Local Interconnection Trunk Group will be totaled
         for the entire monthly bill and then rounded to the next whole minute.

5.2.7    Each Party will provide the other, within thirty (30) calendar days
         after the end of each calendar quarter, a usage report with the
         following information regarding traffic: it sent to (i.e., terminated
         over) the Local Interconnection Trunk arrangements.

 5.2.7.1    Total traffic volume described in terms of minutes and messages and
            by call type (local, toll and other) terminated to each other over
            the Local Interconnection Trunk Groups; and

5.2.7.2     Percent Local Usage ("PLU") and Percent Local Minutes.
<PAGE>

 5.2.8   Upon mutual agreement of the Parties, originating records for local,
         transit, and intraLATA toll traffic shall be exchanged for the purposes
         of billing intercompany terminating compensation.

          5.2.8.1    On a monthly basis, each Party will record its originating
                     MOUs including identification of the originating and
                     terminating NXXs for all intercompany calls.

Each Party will transmit the summarized originating MOUs above to the transiting
and/or terminating Party for subsequent monthly intercompany settlement billing.

          5.2.8.3 Bills rendered by either Party will be paid within thirty (30)
               days of receipt subject to subsequent audit verification.

                  5.2.8.4    MOUs for the rates contained herein will be
                             measured in seconds by call type, and accumulated
                             each billing period into one (1) minute increments
                             for billing purposes in accordance with industry
                             rounding standards.

                  5.2.8.5    Each Party will multiply the tandem routed and end
                             office routed terminating MOUs by the appropriate
                             rate contained in this Section to determine the
                             total monthly billing to each Party.

5.3      Reciprocal Compensation for Termination of Local Traffic

 5.3.1 The Compensation set forth below will apply to all Local Traffic as
defined in Section 5.1.8 of this Agreement.

5.3.2    Applicability of Rates

5.3.2.1  The rates, terms, conditions in this Section 5.3 apply only to the
         termination of Local Traffic, except as explicitly noted.

5.3.2.2 The Parties agree to compensate each other for the termination of Local
Traffic on a minute of use ("MOU') basis.

5.3.3    Rate Elements

 5.3.3.1    A Tandem Served rate element is applicable to Tandem Routed Local
            Traffic on a terminating local MOU basis and includes compensation
            for the following sub-elements:
<PAGE>

                    (a)  Tandem Switching - compensation for the use of tandem
                         switching functions.

                    (b)  Tandem Transport ("Common Transport") compensation for
                         the transmission facilities between the local tandem
                         and the End Offices subtending that tandem.

               (c)  End Office Switching ("Basic Switching Interoffice
                    Terminating") - compensation for the local EO office
                    switching and line termination functions necessary to
                    complete the transmission.

                  5.3.3.2    An End Office Served rate element applies ("Basic
                             Switching Interoffice Terminating") to
                             direct-routed Local Traffic on a terminating local
                             MOU basis and includes compensation for End Office
                             Switching. This includes direct-routed Local
                             Traffic that terminates to offices that have
                             combined tandem and End Office functions.

5.4      Reciprocal Compensation for Transit Traffic

         5.4.1    Transit Traffic allows one Party to send traffic to a third
                  party network through the other Party's tandem. A Transit
                  Traffic rate element applies to all MOUs between a Party and
                  third party networks that transit the other Party's tandem
                  switch. The originating Party is responsible for the
                  appropriate rates unless otherwise specified. The Transit
                  Traffic rate element is only applicable when calls do not
                  originate with (or terminate to) the transit Party's End User.

                  The Tandem Transit Switching rate shall be equal to the Tandem
                  Switching rate plus two times the Common Transport Fixed rate
                  element as specified in Appendix PRICING.

               or   Access Tandem switching when either Party 5.4.2 The transit
                    rate provides f uses the other Party's Access Tandem to
                    originate a call to a third party such as another LEC, CLEC,
                    or Wireless Service Provider.
<PAGE>

 5.4.3   If either Party receives a call through the other Party's Access Tandem
         that originates from another LEC, CLEC or Wireless Service Provider,
         the Party receiving the transited call will not charge the other Party
         any rate element for this call regardless of whether the call is local
         or toll. The Parties will establish appropriate billing relationships
         directly with the Wireless Service Provider, other CLEC or LEC with the
         exception of the independent LECs listed in Section 21.11 of this
         Agreement.

 5.4.4   If such traffic is passed without a third party agreement, CLEC will
         hold NEVADA harmless/indenmify/defend or impose a penalty so that
         NEVADA has protection against third party claims including recovery of

         attorney fees.

               5.5  Reciprocal Compensation for Termination of IntraLATA
                    Interexchange Traffic

For intrastate intraLATA interexchange service traffic, compensation for
termination of intercompany traffic will be at terminating access rates for
Message Telephone Service ("MTS") and originating access rates for 800 Service
as set forth in each Party's Intrastate Access Service Tariff. For interstate
intraLATA intercompany service traffic, compensation for termination of
intercompany traffic will be at terminating access rates for MTS and originating
access rates for 800 Service including the CCL charge, as set forth in each
Party's Interstate Access Service Tariff. The rates charged under this section
by CLEC to NEVADA shall be no greater than the rates contained in NEVADA's
Switched Access tariff.

5.6      Compensation for Origination and Termination of Switched Access Service
   -----------------------------------------------------------------------------
         Traffic to or from an IXC (Meet-Point Billing ("MPB") Arrangements)
----------------------------------------------------------------------------

5.6.1    The Parties will establish MPB arrangements in order to provide
         Switched Access Services to IXCs via NEVADA's Access Tandem switch in
         accordance with the MPB guidelines adopted by and contained in the
         Ordering and Billing Forum's MECOD and MECAB; documents. CLEC's Meet
         Points with NEVADA shall be those identified in Appendix DCO and any
         supplements thereto.

5.6.2    For interstate, interLATA traffic, the Parties will charge IXCs
         according to access rates as set forth in each Party's own applicable
         tariffs.

5.6.3    Billing to IXCs for the Switched Access Services jointly provided by
         the Parties via Meet-Point Billing arrangement shall be according to
         the multiple bill/single tariff method. As described in the MECAB
         document, each Party will render a bill in accordance with its own
         tariff for that portion of the service it provides. For the purpose of
         this Agreement, CLEC is the Initial Billing Company ("IBC") and NEVADA
         is the
<PAGE>

Subsequent Billing Company ("SBC"). The assignment of revenues, by rate element,
and the Meet-Point Billing percentages applicable to this Agreement are set
forth in Appendix DCO. The actual rate values for each element shall be the
rates contained in that Party's own applicable access tariffs.

5.6.4    The Parties will maintain provisions in their respective federal and
         state access tariffs, or provisions within the National Exchange
         Carrier Association ("NECA") Tariff No. 4, or any successor tariff,
         sufficient to reflect this MPB arrangement, including MIPB percentages.

5.6.5    As detailed in the MECAB document, the Parties will, in accordance with
         accepted time intervals, exchange all information necessary to
         accurately, reliably, and promptly bill third Parties for Switched
         Access Services traffic jointly handled by the Parties via the Meet
         Point Arrangement. Each Party reserves the right to charge the other
         Party for the recording/processing functions it performs. Information
         shall be exchanged in Exchange Message Record ("EMR") format, on
         magnetic tape or via a mutually acceptable electronic file transfer
         protocol.

5.6.6    Meet-Point Billing shall also apply to all jointly provided MOU traffic
         bearing the 900, 800, and 888 NPAs or any other non-geographic NPAs
         which may likewise be designated for such traffic in the future where
         the responsible party is an IXC. When NEVADA performs 800 database
         queries, NEVADA will charge the service provider for the database query
         in accordance with standard industry practices and applicable tariffs.

5.6.7    Each Party shall coordinate and exchange the billing account reference
         ("BAR") and billing account cross reference ("BACR") numbers for the
         Meet Point Billing service. Each Party shall notify the other if the
         level of billing or other BAR/BACR elements change, resulting in a new
         BAR/BACR number.

5.6.8    Each Party will provide the other with the Switched Access detailed
         usage data within thirty (30) days of the end of the billing period.
         Each Party will provide to the other the Switched Access summary usage
         data within ten (10) working days after the date that a bill is
         rendered to the IXC by the initial Party. To the extent CLEC provides
         NEVADA with Access Usage Records, NEVADA will compensate CLEC on the
         same terms as CLEC compensates NEVADA. NEVADA acknowledges that
         currently there is no charge for Summary Usage Data Records but that
         such a charge may be appropriate. At CLEC's request, NEVADA will
         negotiate a mutual and reciprocal charge for provision of Summary Usage
         Data Records.
<PAGE>

         5.6.9    Errors may be discovered by CLEC, the IXC or NEVADA. Both
                  NEVADA and CLEC agree to provide the other Party with
                  notification of any discovered errors within two (2) business
                  days of the discovery.

         5.6-10   In the event of a loss of data, both Parties shall cooperate
                  to reconstruct the lost data within sixty (60) days of
                  notification and if such reconstruction is not possible, shall
                  accept a reasonable estimate of the lost data, based upon at
                  least three (3), but no more than twelve (12) months of prior
                  usage data, if available.

5.7      Maintenance of Service

         5.7.1    A Maintenance of Service charge applies whenever either Party
                  requests the dispatch of the other Party's personnel for the
                  purpose of performing maintenance activity on the
                  interconnection trunks, and any of the following conditions
                  exist:

               (a)  no trouble is found in the interconnection trunks; or

               (b)  the trouble condition results from equipment, facilities or
                    systems not provided by the Party whose personnel were
                    dispatched; or

               (c)  trouble clearance did not otherwise require dispatch and,
                    upon dispatch requested for repair verification, the
                    interconnection wink did not exceed Maintenance Limits.

         5.7.2    If a Maintenance of Service initial charge has been applied
                  and trouble is subsequently found in the facilities of the
                  Party whose personnel were dispatched, the charge will be
                  canceled.

         5.7.3    Billing for Maintenance of Service is based on each half-hour
                  or fraction thereof expended to perform the work requested-
                  The time worked is categorized and billed at one of the
                  following three rates:

                  (a)      basic time;

                  (b)      overtime; or

                  (c)      premium time,

               as   defined for billing by NEVADA in NEVADA's revised tariff
                    P.S.C.N. No. C Section 13 and in CLEC's Exchange tariff.

6.       TRANSMISSION AND ROUTING OF SWITCHED ACCESS TRAFFIC

         PURSUANT TO 251(c)(2)

6.1       Scope of Traffic

         Section 6 prescribes parameters for certain trunk groups ("Meet Point
         Trunks") to be established over the Interconnections specified in
         Section 4 above, for the transmission and routing of Switched Access
         traffic between CLEC Telephone Exchange Service End Users and IXCs via
         NEVADA's Access Tandem.

6.2      Trunk Group Architecture and Traffic Routing

 6.2.1   The Parties shall jointly establish two-way Meet Point Trunks as
         described in Appendix ITR, which will jointly provide
         tandem-transported Switched Access Services to IXCs to enable CLEC's
         End Users to originate and terminate traffic to/from such IXCs.

 6.2.2   Meet Point Trunks shall be used solely for the transmission and routing
         of Switched Access to allow CLEC End Users to originate and terminate
         traffic to/from any IXCs which are connected to NEVADA's Access Tandem.
         In addition, the trunks shall be used to allow CLEC's End Users to
         connect to, or be connected to, the Toll Free Services of any
         Telecommunications Carrier connected to NEVADA's Access Tandem.

 6.2.3   The Parties will use separate facilities and separate two-way trunk
         groups to NEVADA's Access Tandem, under which CLEC's NXXs home, using
         DS-1 or DS-3 facilities other than the facilities used for Local
         Interconnection Trunk Groups. Neither Party will charge the other any
         amount for any Meet Point facilities.

 6.2.4   NEVADA will not offer blocking capability for Switched Access customer
         traffic delivered to any NEVADA tandem for completion on CLECs network.
         The Parties understand and agree that Meet Point Trunking arrangements
         are available and functional only to/from Switched Access customers who
         directly connect with any NEVADA tandem that CLEC subtends; in each
         LATA. In no event will NEVADA be required to route such traffic through
         more than one tandem for connection to/from Switched Access customers.
         NEVADA shall have no responsibility to ensure that any Switched Access
         customer will accept traffic that CLEC directs to the Switched Access
         customer. NEVADA also agrees to furnish CLEC, upon request, a list of
         those IXCs which also interconnect with NEVADA's tandem.
<PAGE>

                  6.2.5    CLEC will provide all CCS signaling including,
                           without limitation, Charge Number and originating
                           line information ("OLI"). For terminating FGD, NEVADA
                           will pass all CCS signaling including, without
                           limitation,

CPN  if it receives CPN from FGD carriers. All privacy indicators will be

                           honored- Network signaling information such as
                           Transit Network Selection ("TNS") parameter, Carrier
                           Identification Codes ("CIC"), (CCS platform) and
                           CIC/OZZ information (non-CCS environment) will be
                           provided by CARRIER wherever such information is
                           needed for call routing or billing. The Parties will
                           follow all OBF adopted standards pertaining to TNS
                           and CIC/OZZ codes.

7.       TRANSPORT AND TERMINATION OF OTHER TYPES OF TRAFFIC

7.1      Information Services Traffic

         At such time as the Parties agree to route intraLATA Information
         Services Traffic to one another-, they shall agree to exchange rating
         and billing information to effectively allow the Parties to bill their
         End Users and to charge reciprocal rates.

7.2      Busy Line Verification ("BLV")/Busy Line Verification/Interrupt
         ("BLVI") Traffic

7.2.1    Each Party's operator bureau shall accept BLV and BLVI inquiries from
         the operator bureau of the other Party in order to allow transparent
         provision of BLV/BLVI Traffic between the Parties' networks.

               7.2.2 Each Party shall route BLV/BLVI Traffic inquiries betwee.
                    respective operator bureaus over Local Interconnection trunk
                    Appendix ITR.

8.       SIGNALING

8.1      The Parties will interconnect their networks using SS7 signaling as
         defined in

         GR-000317-CORE7 and GR-000394-CORE, including ISDN User Part ("ISUP")
         for trunk signaling and Transaction Capabilities Application Part
         ("TCAP") for CCS-based features in the interconnection of their
         networks. Either Party may establish CCS interconnections either
         directly and/or through a third party. Whether direct, or by third
         party, CCS interconnection shall be pursuant to PUB L-780023-PB/NB: If
         CCS interconnection is established through a third party, the rates,
         terms, and conditions of the parties' respective tariffs will apply. If
         CCS Interconnection is established directly between CLEC and NEVADA,
         the rates, terms, and conditions of Appendix SS7 will apply.
<PAGE>

8.2      The Parties will cooperate in the exchange of TCAP messages to
         facilitate full interoperability of CCS-based features between their
         respective networks, including all CLASS features and functions, to the
         extent each carrier offers such features and functions to its own End
         Users. All CCS signaling parameters deployed by both Parties will be
         provided including CPN. All privacy indicators will be honored.

8.3      CCS shall be used in conjunction with Meet Point Trunks; except
         multifrequency ("MF") signaling will be used on a separate Meet Point
         Trunk Group to complete originating calls to Switched Access customers
         that use MF FGD signaling protocol. MY and CCS trunk groups shall not
         be provided within a DS- I facility; a separate DS-1 per signaling type
         must be used.

         8.4      Originating FGB calls delivered to NEVADA's tandem shall use
                  GR-317 signaling format unless the associated FGB carrier
                  employs GR-394 signaling for its FGB traffic at the serving
                  Access Tandem.

9.       NUMBERING

9.1      Nothing in this Agreement shall be construed to limit or otherwise
         adversely impact in any manner either Party's right to employ or to
         request and be assigned any North American Numbering Plan ("NANP")
         number resources including, but not limited to, central office ('NXX")
         codes pursuant to the Central Office Code Assignment Guidelines', or to
         establish, by tariff or otherwise, Exchanges and Rating Points
         corresponding to such NXX codes. Each Party is responsible for
         administering the NXX codes it is assigned.

9.2      At a minimum, in those areas where CLEC intends to provide
         facilities-based local exchange service, CLEC shall obtain one NXX per
         incumbent local exchange carrier rate center which is required to
         ensure compliance with the industry-approved Central Office Code NXX
         Assignment Guidelines (April, 1997) and the FCC's Second Report and
         Order in CC Docket 96-116 released August 18, 1997 (Local Number
         Portability).

9.3      Each Party agrees to make available via the LERG, up-to-date listings
         of its own assigned NPA-NXX codes, along with associated Rating Points
         and Exchanges.

9.4      To the extent NEVADA serves as Central Office Code Administrator for a
         given region, NEVADA commits to treat CLEC requests for assignment of
         central office code(s) in a neutral and nondiscriminatory manner,
         consistent with

I Last published by the Industry Numbering Committee ("INC") as INC 95-0407-008,
Revision April 1997, formerly ICCF 93-0729-010.
<PAGE>

     regulatory requirements, and ('NXX") Central Office Code Assignment
     Guidelines. Currently Pacific Bell performs this function for NEVADA.

9.5      Each Party is responsible to program and update its own switches and
         network systems to recognize and route traffic to the other Party's
         assigned NXX codes at all times. Neither Party shall impose fees or
         charges on the other Party for such required programming and updating
         activities.
9.6      Each Party is responsible to input required data into the Routing Data
         Base Systems ("RDBS") and into the Bellcore Rating Administrative Data
         Systems ("BRADS") or other appropriate system(s) necessary to update
         the Local Exchange Routing Guide ("LERG"), unless negotiated otherwise.

9.7      Upon the request of CLEC, NEVADA shall perform LERG input for CLEC.
         CLEC agrees to pay NEVADA the sum of $I 10 per NXX in exchange for
         NEVADA's input of required data necessary to update the Local Exchange
         Routing Guide ("LERG") on CLEC's behalf. NEVADA shall not be liable for
         any losses or damages arising out of errors, defects, or failures
         associated with the input of CLEC's data into the LERG.

9.8      Neither Party is responsible for notifying the other Parties' End Users
         of any changes in dialing arrangements, including those due to NPA
         exhaust, unless otherwise ordered by the law, the Commission, the FCC,
         or a court.
9.9      NXX Migration
         Where either Party has activated an entire NXX for a single End User,
         or activated more than half of an NXX for a single End User with the
         remaining numbers in that NXX either reserved for future use or
         otherwise unused, if such End User chooses to receive service from the
         other Party, the first Party shall cooperate with the second Party to
         have the entire NXX reassigned in the LERG (and associated industry
         databases, routing tables, etc.) to an End Office operated by the
         second Party. Such transfer will require development of a transition
         process to minimize impact on the Network and on the End User(s)'
         service and will be subject to appropriate industry lead times
         (currently forty-five (45) days) for movements of NXXs from one switch
         to another. The Party to whom the NXX is migrated will pay NXX
         migration charges of $10,000 per NXX to the Party formerly assigned the
         NXX.

                  for internal referrals, to solicit customers, or to market
                  services, nor shall they initiate extraneous communications
                  beyond the direct referral to the correct repair telephone
                  number.

21.      GENERAL RESPONSIBILITIES OF THE PARTIES

21.1     Implementation Schedule

         Upon approval by the PUC of Nevada, CLEC agrees to begin providing
         telephone exchange service to business customers within (NUMBER OF
         DAYS) days and to residential customers within (NUMBER OF DAYS) days
         within its certificated service area.

 21.2 NEVADA and CLEC shall each use their best efforts to meet the
Interconnection Activation Dates.

 21.3    Each Party is individually responsible to provide facilities within its
         network that are necessary for routing, transporting, measuring, and
         billing traffic from the other Party's network and for delivering such
         traffic to the other Party's network in the standard format compatible
         with NEVADA's network as referenced in Bellcore's BOC Notes on LEC
         Networks Practice No. SR-TSV-002275, and to terminate the traffic it
         receives in that standard format to the proper address on its network.
         The Parties are each solely responsible for participation in and
         compliance with national network plans, including the National Network
         Security Plan and the Emergency Preparedness Plan.

 21.4    Neither Party shall use any service related to or use any of the
         services or elements provided in this Agreement in any manner that
         interferes with other persons in the use of their service, prevents
         other persons from using their service, or otherwise impairs the
         quality of service to other carriers or to either Party's End Users.
         Either Party may discontinue or refuse service, but only for so long as
         the other Party is violating this provision. Upon such violation,
         either Party shall provide the other Party notice of the violation at
         the earliest practicable time.

     21.5 Each Party is solely responsible for the services it provides to its
     End Users and to other Telecommunications Carriers.

 21.6    The Parties shall work cooperatively to minimize fraud associated with
         third-number billed calls, calling card calls, and any other services
         related to this Agreement.

     21.7 At all times during the term of this Agreement, each Party shall keep
     and maintain in force at each Party's expense all insurance required by law
     (e.g. workers' compensation insurance) as well as general liability
     insurance for personal injury or death to any one person, property damage
     resulting from any one incident, and automobile liability with coverage for
     bodily injury for property damage. Upon
<PAGE>

request from the other Party, each Party shall provide to the other Party
evidence of such insurance (which may be provided through a program of self
insurance).

 21.8    Unless otherwise stated, each Party will render a monthly bill to the
         other for service(s) provided hereunder. Remittance in full will be due
         within thirty (30) days of that billing date. Interest shall apply on
         overdue amounts (other than disputed amounts which are subject to
         Section 30.12) at the rate specified in Section 30.12, unless otherwise
         specified in an applicable tariff. Each Party reserves the right to net
         delinquent amounts against amounts otherwise due the other.

 21.9    NEVADA is participating with the industry to develop standardized
         methods through the OBF and shall implement ordering and billing
         formats/processes consistent with industry guidelines as capabilities
         are deployed. Where such guidelines are not available or NEVADA decides
         not to fully utilize industry guidelines, NEVADA will provide CLEC with
         information on its ordering and billing format/process and requirements
         at the earliest practicable time.

     21-10 NEVADA in its role as Designated Carrier for LATA 720, as established
     by the PUC of Nevada in Docket 86-711, has the responsibility to transport
     originating and terminating traffic for embedded independent local exchange
     carriers under special compensation arrangements. The independent LECs that
     participate in the Designated Carrier Plan ("DCP") are Churchill County
     Telephone & Telegraph, Continental Telephone Company of Nevada ("GTE"),
     C.P. National Corporation (Citizens Telecom), Lincoln County Telephone
     Company, Humboldt Telephone, and Rural Telephone Company. NEVADA is bound
     to continue this arrangement until such time as NEVADA has interconnection
     agreements with all of the embedded independent LECs and the PUC of Nevada
     agrees to discontinue the DCP. All traffic under this plan is independent
     LEC Int-aLATA Toll traffic. Under the DCP, the independent LECs bill NEVADA
     for both originating and terminating access at rates designed to recover
     their relevant costs. NEVADA does not bill the independent LECs any access
     for originating or terminating their traffic. The independent LECs pass the
     toll. revenue associated with their originating traffic to NEVADA as
     compensation to NEVADA for the =sport of their traffic. To meet the
     requirements of the DCP, CLEC agrees to the following stipulations for
     compensation as it pertains to both originating and terminating traffic
     from the participating independent LECs.

 21.10.1    All traffic for the participating independent LECs that transit
            NEVADA's network will be treated for compensation (rating) as if the
            call originated or terminated in NEVADA's network. At such time that
            the DCP is discontinued, this Section 21.11 will no longer apply and
            the compensation and rating defined in this Agreement will be used
            without exception.
<PAGE>

21.10.2    CLEC will not be required to establish an appropriate billing
           relationship directly with the independent LECs for traffic under the
           DCP until such

           time as the DCP is discontinued.

 21-11   For the purposes of establishing provisioning and billing service- to
         the CLEC, the CLEC is required to provide to NEVADA its state-specific
         authorized and nationally recognized OCN/AECNs for facilities-based
         business (interconnection and/or Unbundled Network Elements) in each
         NEVADA state and a single separate and distinct OCN/AECN for resale
         services in any NEVADA state. CLEC name associated with specific resale
         OCN/AECN must be consistent among NEVADA states.

         21.12    Unless otherwise agreed, if the designated Party fails to file
                  the jointly signed agreement with the Commission within thirty
                  (30) days of both Parties signatures, then the signed
                  agreement is null and no longer valid. If the contract becomes
                  null, either Party can initiate negotiations to a new
                  agreement.

22.      EFFECTIVE DATE, TERM. AND TERMINATION

 22.1    This Agreement shall be effective ten (10) days after approval by the
         PUC of Nevada when it has determined that the Agreement complies with
         Sections 251 and 252 of the Act ("Effective Date').

22.2     The initial term of this Agreement shall expire on October 25, 2000.
         Absent the receipt by one Party of written notice from the other Party
         at least sixty (60) days prior to the expiration of the Term to the
         effect that such Party does not intend to extend the Term of this
         Agreement, this Agreement shall automatically renew and remain in full
         force and effect on and after the expiration of the Term until
         terminated by either Party pursuant to Section 22.3, below.

22.3     Either Party may terminate this Agreement in the event that the other-
         Party fails to perform a material obligation that disrupts the
         operation of either Party's network and/or End User service and fails
         to cure such material nonperformance within forty-five (45) days after
         written notice thereof

22.4     If pursuant to Section 22.2, above, this Agreement continues in full
         force and effect after the expiration of the Term, either Party may

         notice to the other Party of its intention to terminate this Agreement,
         subject to Section 22.5, below. Neither Party shall have any liability
         to the other Party for termination of this Agreement pursuant to this
         Section 22.4 other than its obligations under Section 22.5, below.
<PAGE>

          22.5 Upon termination or expiration of this Agreement in accordance
with this Section 22, above:

     (a) each Party shall comply immediately with its obligations set forth in
Section 30.6, below; and

     (b) each Party shall promptly pay all amounts (including any late payment
charges) owed under this Agreement; and

     (c) each Party's indemnification obligations shall survive.

          22.6    If upon expiration or termination the Parties are negotiating
                  a successor agreement, during such period each Party shall
                  continue to perform its obligations and provide the services
                  described herein that are to be included in the successor
                  agreement until such time as the latter agreement becomes
                  effective; provided however, that if the Parties are unable to
                  reach agreement within six (6) months after termination or
                  expiration of this Agreement, either Party has the right to
                  submit this matter to the Commission for resolution. Until a
                  survivor agreement is reached or the Commission resolves the
                  matter, whichever is sooner, the terms, conditions, rates, and
                  charges stated herein will continue to apply, subject to a
                  true-up based on the Commission action, if any.

         22.7     No remedy set forth in this Agreement is intended to be
                  exclusive and each and every remedy shall be cumulative and in
                  addition to any other rights or remedies now or hereafter
                  existing under applicable law or otherwise.

23.      DISCLAIMER OF REPRESENTATIONS AND WARRANTIES

         EXCEPT AS EXPRESSLY PROVIDED UNDER THIS AGREEMENT, NO PARTY MAYES OR
         RECEIVES ANY WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE
         SERVICES, FUNCTIONS AND PRODUCTS IT PROVIDES UNDER OR CONTEMPLATED BY
         THIS AGREEMENT AND THE PARTIES DISCLAIM THE IMPLIED WARRANTIES OF
         MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE. ADDITIONALLY,
         NEITHER NEVADA NOR CLEC ASSUMES RESPONS113ELITY WITH REGARD TO THE
         CORRECTNESS OF DATA OR INFORMATION SUPPLIED BY THE OTHER WHEN THIS DATA
         OR INFORMATION IS ACCESSED AND USED BY A THIRD PARTY.

24.      CHANGES IN END USER LOCAL EXCHANGE SERVICE PROVIDER SELECTION

         Each Party will abide by applicable state or federal laws and
         regulations in obtaining End User authorization prior to changing End
         User's local service provider to itself and in assuming responsibility
         for any applicable charges as specified in Section 258(b) of the
<PAGE>

         Telecommunications Act of 1996. CLEC shall make authorization available
         to NEVADA upon request and at no charge. Only an End User can initiate
         a challenge to a change in its local exchange service provider. If an
         End User notifies NEVADA or CLEC that the End User requests local
         exchange service, the Party receiving such request shall be free to
         immediately provide service to such End User. When an End User changes
         or withdraws authorization, each Party shall release customer-specific
         facilities in accordance with the End User's direction or the End
         User's authorized agent. Further, when an End User abandons the
         premise, NEVADA is free to reclaim the unbundled network element
         facilities for use by another customer and is free to issue service
         orders required to reclaim such facilities.

25.      SEVERABILITY

                  Interconnection, terms and conditions of this Agreement as a
                  total arrangement and it is intended to be nonseverable,
                  subject only to Section 30.16 of this Agreement.

         25.2     In the event the Commission, the FCC, or a court rejects any
                  portion or determines that any provision of this Agreement is
                  contrary to law, or is invalid or unenforceable for any
                  reason, the Parties shall continue to be bound by the terms of
                  this Agreement, insofar as possible, except for the portion
                  rejected or determined to be unlawful, invalid, or
                  unenforceable. In such event, the Parties shall negotiate in
                  good faith to replace the rejected, unlawful, invalid, or
                  unenforceable provision and shall not discontinue service to
                  the other Party during such period if to do so would disrupt
                  existing service being provided to an End User. Nothing in
                  this Agreement shall be construed as requiring or permitting
                  either Party to contravene any mandatory requirement of
                  federal or state law, or any regulations or orders adopted
                  pursuant to such law.

26.      INTELLECTUAL PROPERTY

         CLEC as the provider of the Unbundled Network Elements will provide all
         features, functions, and capabilities of the individual elements.
         NEVADA will provide a list of all vendors/licensors applicable to the
         subject Unbundled Network Element(s) (which vendors have provided
         NEVADA a software license) within seven (7) days of a request for such
         a list by CLEC. NEVADA agrees to use its best efforts to facilitate the
         obtaining of any necessary license or right to use agreement. NEVADA
         makes no warranties, express or implied, concerning CLEC's (or any
         third party's) rights with the respect to use of intellectual property
         (including without limitation, patent, copyright, and trade secret
         rights). NEVADA reserves the right to amend the Intellectual Property
         provision of this Agreement to reflect the FCC ruling (and any appeal
         therefrom) in CC Docket No. 96-98 (File No. CCBPol 97-4), In the Matter
         of Petition of MCI for Declaratory Ruling.

         27.2     Except as otherwise provided herein or in specific appendices,
                  and to the extent not prohibited by law and not otherwise
                  controlled by tariff, each Party (the "Indemnifying Party")
                  shall defend and indemnify the other Party (the "Indemnified
                  Party) and hold such Indemnified Party harmless against any
                  loss to a third party arising out of the negligence or willful
                  misconduct by such Indemnifying Party, its agents, its End
                  User, contractors, or others retained by such parties, in
                  connection with the indemnifying provision of services or
                  functions under this Agreement.

                  other Party ("Indemnified Party") against any and all such
                  claims or loss by its End Users regardless of whether the
                  underlying service was provided or unbundled element was
                  provisioned by the Indemnified Party, unless the loss was
                  caused by the gross negligence or intentional misconduct of
                  the other ("Indemnified") Party.

         27.4     CLEC agrees to indemnify, defend and hold harmless NEVADA and

                  use of the 911 service, whether suffered, made, instituted, or
                  asserted by CLEC or its End Users, including for any personal
                  injury or death of any person or persons, except for loss
                  which is the direct result of NEVADA's or Pacific Bell's own
                  negligence or willful misconduct.

         27.5     NEVADA shall not be liable for damages to an End User's
                  premises resulting from the furnishing of unbundled elements,
                  including the installation and removal of equipment and
                  associated wiring, unless the damage is caused by NEVADA's
                  negligence or willful misconduct. NEVADA does not guarantee or

         appendices. The Indemnified Party agrees to notify the Indemnifying
         Party promptly in writing of any written claims, lawsuits or demands

         subject to or limited by intellectual property (including, without
         limitation, patent, copyright, and trade secret rights) and contract
         rights of third parties. It is the sole obligation of CLEC to obtain
         any consents, authorizations, or licenses under intellectual property
         or proprietary rights held by third parties that may be necessary for
         its use of NEVADA network facilities under this Agreement. NEVADA
         hereby conveys no licenses to use such intellectual property rights and
         makes no warranties, express or implied, concerning CLEC's (or any
         third party's) rights with respect to such intellectual property and
         contract rights, including, without limitation, whether such rights
         will be violated by such interconnection or unbundling and/or combining
         of elements (including combining with CLEC's network elements) in
         NEVADA's network. NEVADA does not and shall not indemnify or defend,
         nor be responsible for indemnifying or defending CLEC for any liability
         losses, claims, costs, damages, demand, penalties, or other expenses
         arising out of, caused by, or relating to CLEC's interconnection with
         NEVADA's network and
<PAGE>

unbundling and/or combining NEVADA's network elements (including combining with
CLEC's network elements).

 27.9    CLEC agrees to indemnify and hold NEVADA harmless from and against all
         liability, losses, claims, costs, damages, demand, penalties, or other
         expenses, including but not limited to costs of litigation and
         reasonable attorneys fees, arising out of, caused by, or relating to
         any real or potential claim, demand, or action that CLEC's
         interconnection with NEVADA's network, or CLEC's use of services or
         functions offered hereunder, or unbundling and/or combining of NEVADA's
         network elements (including combining with CLEC's network elements)
         violates or infringes upon any intellectual property rights of any
         third party or constitutes a breach of contract. CLEC shall notify
         NEVADA in writing within ten (10) days after CLEC receives notification
         of any claim or suit subject to this provision. NEVADA shall undertake
         and control the defense and settlement of any such claim or suit and
         CLEC shall cooperate fully with NEVADA in connection herewith. In no

         profits which CLEC may suffer arising out of same.

         27.10    CLEC shall reimburse NEVADA for damages to NEVADA facilities
                  utilized to provide unbundled elements hereunder caused by the
                  negligence or willful act of CLEC or resulting from CLEC's
                  improper use of NEVADA facilities, or due to malfunction of
                  any facilities or equipment provided by other than NEVADA.
                  Nothing in the foregoing provision shall be interpreted to
                  hold one CLEC liable for another local service provider or End
                  User's actions. Upon reimbursement for damages, NEVADA will
                  cooperate with CLEC in prosecuting a claim against the person
                  causing such damage. CLEC shall be subrogated to the right of
                  recovery by NEVADA for the damages to the extent of such
                  payment.

         the FCC and the Act. For all claims under this Agreement that are based
         upon issues within the jurisdiction (primary or otherwise) of the

                    resale tax exemption certificate as authorized or required
                    by statute or regulation by the jurisdiction providing said
                    resale tax exemption. Failure to timely provide said resale
                    tax exemption certificate will result in no exemption being
                    available to the purchasing Party until such time as the
                    purchasing Party presents a valid certificate.

         30.8.2   With respect to any purchase of services, facilities or other
                  arrangements, if any Tax is required or permitted by
                  applicable law to be collected from the purchasing Party by
                  the providing Party, then:

               (a)  the providing Party shall bill the purchasing Party for such
                    Tax;

               (b)  the purchasing Party shall remit such Tax to the providing
                    Party; and
<PAGE>

          (c) the providing Party shall remit such collected Tax to the
          applicable

                  taxing authority.

 30.8.3   With respect to any purchase hereunder of services, facilities or
          arrangements that are resold to a third party, if any Tax is imposed
          by applicable law on the End User in connection with any such
          purchase, then:

(a)      the purchasing Party shall be required to impose and/or collect

         such Tax from the End Useq and

(b)      the purchasing Party shall remit such Tax to the applicable taxing

         authority.

The purchasing Party agrees to indemnify and hold harmless the providing Party
on an after-tax basis for- any costs incurred by the providing Party as a result
of actions taken by the applicable taxing authority to collect the Tax from the
providing Party due to the failure of the purchasing Party to pay or collect and
remit such tax to such authority.

30.8.4   If the providing Party fails to collect any Tax as required herein,
         then, as between the providing Party and the purchasing Party:

          (a) the purchasing Party shall remain liable for such uncollected Tax;
          and

 (b)      the providing Party shall be liable for any penalty and interest
          assessed with respect to such uncollected Tax by such authority.

However, if the purchasing Party fails to pay any taxes properly billed, then,
as between the providing Party and the purchasing Party, the purchasing Party
will be solely responsible for payment of the taxes, penalty and interest.

 30.8.5   If the purchasing Party fails to: impose and/or collect any Tax from
          End Users as required herein, then; a.& between the providing Party
          and the purchasing Party, the purchasing Party shall remain liable for
          such uncollected Tax and any interest and penalty assessed thereon
          with respect to the uncollected Tax by the applicable taxing
          authority. With respect to any Tax that the purchasing Party has
          agreed to pay or impose on and/or collect from End Users, the
          purchasing Party agrees to indemnify and hold harmless the providing
          Party on an after-tax basis for any costs incurred by the providing
          Party as a result of actions taken by the applicable taxing
<PAGE>

                  authority to collect the Tax from the providing Party due to
                  the failure of the purchasing Party to pay or collect and
                  remit such Tax to such authority.

30.9 Non-Assignment

         Each Party covenants that, if it sells or otherwise transfers to a
         third party its Telephone Exchange and Switched Access network
         facilities within any territory within which NEVADA is an Incumbent
         Local Exchange Carrier as of the date of this Agreement ("NEVADA's
         Territory"), or any portion thereof, to a third party, it will require
         as a condition of such transfer that the transferee agree to be bound
         by this Agreement with respect to services provided over the
         transferred facilities. Except as provided in this paragraph, neither
         Party may assign or transfer (whether by operation of law or otherwise)
         this Agreement (or any rights or obligations hereunder) to a third
         party without the prior written consent of the other Party; provided
         that each Party may assign this Agreement to a corporate Affiliate or
         an entity under its common control or an entity acquiring all or
         substantially all of its assets or equity by providing prompt written
         notice to the other Party of such assignment or transfer. Any attempted
         assignment or transfer that is not permitted is void ab initio. Without
         limiting the generality of the foregoing, this Agreement shall be
         binding upon and shall inure to the benefit of the Parties' respective
         successors and assigns.

30.10 Non-Waiver

         Failure of either Party to insist on performance of any term or
         condition of this Agreement or to exercise any right or privilege
         hereunder shall not be construed as a continuing or future waiver of
         such term, condition, right or privilege.

30.11 Audits

Each Party to this Agreement will be responsible for the accuracy and quality of
its data as submitted to the respective Parties involved.

 30.11.1    Upon reasonable written notice and at its own expense, each Party or
            its authorized representative (providing such authorized
            representative does not have a conflict of interest related to other
            matters before one of the Parties) shall have the right to conduct
            an audit of the other Party to give assurances of compliance with
            the provisions of this Agreement; provided, that neither Party may
            request more than two (2) such audits within any twelve (12) month
            period. This includes on-site audits at the other Party's or the
            Party's vendor locations. Each Party, whether or not in connection
            with an audit, shall maintain reasonable records for a minimum of
            twenty-four (24) months and provide the other Party with reasonable
            access to such information as is necessary to determine
<PAGE>

                    amounts receivable or payable under this Agreement. Each
                    Party's right to access information for audit purposes is
                    limited to data not in excess of twenty-four (24) months in
                    age.

30.12 Disputed Amounts

 30.12.1    No claims, under this Agreement or its Appendices, shall be brought
            for disputed amounts more than twenty-four (24) months from the date
            of occurrence which gives rise to the dispute. Under this Section
            30.12, if any portion of an amount due to a Party (the "Billing
            Party") under this Agreement is subject to a bona fide dispute
            between the Parties, the Party billed (the "Non-Paying Party") shall
            within sixty (60) days of its receipt of the invoice containing such
            disputed amount give notice to the Billing Party of the amounts it
            disputes ("Disputed Amounts") and include in such notice the
            specific details and reasons for disputing each item. The Non-Paying
            Party shall pay when due:

            (a) all undisputed amounts to the Billing Party; and

            (b) all Disputed Amounts to the Billing Party.

 30.12.2    If the Parties are unable to resolve the issues related to the
            Disputed Amounts in the normal course of business within sixty (60)
            days after delivery to the Billing Party of notice of the Disputed
            Amounts, each of the Parties shall appoint a designated
            representative who has authority to settle the dispute and who is at
            a higher level of management than the persons with direct
            responsibility for administration of this Agreement. The designated
            representatives shall meet as often as they reasonably deem
            necessary in order to discuss the dispute and negotiate in good
            faith in an effort to resolve such dispute.

 30-12.3    If the Parties are unable to resolve issues related to the Disputed
            Amounts within forty-five (45) days after the Parties' appointment
            of designated representatives pursuant to Section 30.12.2, above,
            then either Party may file a complaint with the Commission to
            resolve such issues or proceed with any other remedy pursuant to law
            or equity.

 30.12.4    The Parties agree that all negotiations pursuant to this Section
            30.12 shall remain confidential and shall be treated as compromise
            and settlement negotiations for purposes of the Federal Rules of
            Evidence and state rules of evidence.

 30.12.5 Any undisputed amounts not paid when due shall accrue interest from the
date such amounts were due at the lesser of.
<PAGE>

                    (a)    one and one-half percent (1-1/2%) per month; or

     (b) the highest rate of interest that may be charged under applicable law.

30.13 Dispute Resolution

         30.13.1    No claims shall be brought for disputes arising under this
                    Agreement or its Appendices more than twenty-four (24)
                    months from the date of occurrence which gives rise to the
                    dispute.

         30.13.2    For disputes other than disputed amounts under this
                    Agreement or its Appendices, each Party shall appoint a
                    designated representative as set forth in Section 30.12.2,
                    above, and if unable to resolve the dispute, proceed as set
                    forth in Section 30.12.3, above.

30.14 Notices

         Any notice to a Party required or permitted under this Agreement shall
         be in writing and shall be deemed to have been received on the date of
         service if served personally; on the date receipt is acknowledged in
         writing by the recipient if delivered by regular mail; or on the date
         stated on the receipt if delivered by certified or registered mail or

30.15 Publicity and Use of Trademarks or Service Marks

34-15.1    The Parties agree not to use in any advertising or sales promotion,
           press releases, or other publicity matters any endorsements, direct
           or indirect quotes, or pictures implying endorsement by the other
           Party or any of its employees without such Party's prior written
           approval. The Parties will submit to each other for written approval,
           prior to publication, all publicity matters that mention or display
           one another's name and/or marks or contain language from which a
           connection to said name and/or marks may be inferred or implied; the
           Party to whom a request is directed shall respond promptly. Nothing
           herein, however, shall be construed as preventing either Party from
           publicly stating the fact that it has executed this Agreement with
           the other Party.

         30.15.2    Nothing in this Agreement shall grant, suggest, or imply any
                    authority for one Party to use the name, trademarks, service
                    marks, or trade names of the other for commercial purposes
                    without prior written approval.

30.16 Section 252(i) Obligations

If either Party enters into an agreement (the "Other Agreement") approved by the
Commission or FCC pursuant to Section 252 of the Act (regardless of whether the
approved agreement was negotiated or arbitrated) which provides for the
provision of arrangements covered in this Agreement to another requesting
Telecommunications Carrier, including an Affiliate, such Party shall make
available to the other Party such arrangements upon the same rates, terms and
conditions as those provided in the Other Agreement. At its sole option, the
other Party may avail itself of either:

30.16.1     the Other Agreement in its entirety; or

30.16.2 the prices, terms and conditions of the Other Agreement that directly
relate to any of the following duties as a whole:

               (a)  Interconnection - Section 25 1 (c)(2); 252(d)(1); and
                    271(c)(2)(B)(i) of the Act; or

               0)   Directory Assistance - Section 27 1 (c)(2)(B)(vii)(II).

30.17 Joint Work Product


         This Agreement is the joint work product of the Parties and has been
         negotiated by the Parties and their respective counsel and shall be
         fairly interpreted in accordance with its terms and, in the event of
         any ambiguities, no inferences shall be drawn against either Party.

30.18 Intervening Law

         This Agreement is entered into as a result of both private negotiation
         between the Parties and the incorporation of some of the results of
         arbitration by the Public Utilities Commission of Nevada. If the
         actions of the State of Nevada or federal legislative bodies, courts,
         or regulatory agencies of competent jurisdiction invalidate, modify, or
         stay the enforcement of laws or regulations that were the basis for a
         provision of the contract, the affected provision shall be invalidated,
         modified, or stayed, consistent with the action of the legislative
         body, court, or regulatory agency. In such event, the Parties shall
         expend diligent efforts to arrive at an agreement respecting the
         modifications to the Agreement. If negotiations fail, disputes between
         the Parties concerning the interpretation of the actions required or
         provisions affected by such governmental actions shall be resolved
         pursuant to the dispute resolution process provided for in this
         Agreement.

30.19 No Third Party Beneficiaries; Disclaimer of Agency

This Agreement is for the sole benefit of the Parties and their permitted
assigns, and nothing herein express or implied shall create or be construed to
create any third-party beneficiary rights hereunder. Except for provisions
herein expressly authorizing a Party to act for another, nothing in this
Agreement shall constitute a
<PAGE>

         Party as a legal representative or agent of the other Party, nor shall
         a Party have the right or authority to assume, create or incur any
         liability or any obligation of any kind, express or implied, against or
         in the name or on behalf of the other Party unless otherwise expressly
         permitted by such other Party. Except as otherwise expressly provided
         in this Agreement, no Party undertakes to perform any obligation of the
         other Party, whether regulatory or contractual, or to assume any
         responsibility for the management of the other Party's business.

30.20 No License

         No license under patents, copyrights or any other intellectual property
         right (other than the limited license to use consistent with the terms,
         conditions and restrictions of this Agreement) is granted by either
         Party or shall be implied or arise by estoppel with respect to any
         transactions contemplated under this Agreement.

30.21 Survival

         The Parties' obligations under this Agreement which by their nature are
         intended to continue beyond the termination or expiration of this
         Agreement shall survive the termination or expiration of this
         Agreement.

30-22 Scope of Agreement

         This Agreement is intended to describe and enable specific
         Interconnection and compensation arrangements between the Parties. This
         Agreement does not obligate either Party to provide arrangements not
         specifically provided herein.

30.23 Entire Agreement

The terms contained in this Agreement and any Schedules, Exhibits, Appendices,
tariffs and other documents or instruments referred to herein, which are
incorporated into this Agreement by this reference, constitute the entire
agreement between the Parties with respect to the subject matter hereof
superseding all prior understandings, proposals and other communications, oral
or written. Neither Party shall be bound by any preprinted terms additional to
or different from those in this Agreement that may appear subsequently in the
other Party's form documents, purchase orders, quotations, acknowledgments,
invoices or other communications. This Agreement may only be modified in writing
signed by an officer of each Party.

   This Agreement is entered into pursuant to an arbitration order of the Nevada
Public Utility Commission, Docket No. 99-1007, Order Adopting Revised
Arbitration Decision, April 12, 1999. It contains provisions with which Nevada
Bell does not agree and as to which there was and is no meeting of the minds of
the parties. In particular, there was and is no agreement that Internet traffic
would be subject to reciprocal compensation as Local Traffic under this
agreement. The FCC has repeatedly asserted its interstate jurisdiction over
Internet traffic, including as recently as in its Declaratory Ruling in CC
Docket 96-98, released February 26, 1999, in which the FCC expressly confirmed
that Internet bound traffic is non-local interstate traffic. For this reason,
Nevada Bell believes that Internet traffic is excluded from this Agreement and
is not subject to reciprocal compensation. Nevada Bell fully reserves it rights
on this issue. Nevada Bell believes it is entitled, under this Agreement, to
receive access charges for facilities used in the carriage of traffic originated
in a local calling area but transported beyond that local calling area to
centralized modem locations in Nevada by a toll-free incoming service,
including, but not limited to, 800 service, 800-like service and foreign
exchange-like service.

**Pac-West disagrees with Nevada Bell's characterization of both this agreement
and the FCC's ruling on the issues regarding telephone calls terminating on the
Internet. Pac-West disagrees with Nevada Bell's characterization of the impact
of the FCC's ruling on this agreement. This agreement speaks for itself. The
addendum to the Pacific Bell signature has no bearing on the fashion in which
the respective rights of the parties to this agreement are determined.

APPENDIX AIN

AIN CALL RELATED DATABASE

1.       SERVICE

Advanced Intelligent Network ("AIN") is a Network Architecture that uses
distributed intelligence in centralized databases to control call processing and
manage network information, rather than performing those functions in every
switch.

At such time as NEVADA deploys AIN in its network, the following provisions will
apply:

1.1      NEVADA will provide CLEC access to NEVADA's Service Creation

         Environment ("SCE") to design, create, test, and deploy AIN-based
         features. All AIN services will require testing in Pacific Bell's AIN
         laboratory prior to deployment into the network. Testing will ensure
         compatibility with NEVADA's network nodes and interaction with other
         AIN, 800/888 and LIDB services. Testing will validate billing of both
         switched and database services and other switch-based features, and
         ensure appropriate use of network resources.

1.2      Access to NEVADA's SCE
         CLEC may choose among the following forms of access to NEVADA's SCE:

         (a)      Option I -
            ---------------

                  CLEC provides NEVADA with documentation and logic design for
                  the desired service. NEVADA personnel will operate the AIN SCE
                  terminal to create the service as described by CLEC.

(b)      Option 2 -
   ---------------

         CLEC personnel will operate NEVADA's SCE terminal themselves. Option 2
         will be made available when partitioning of NEVADA's SCE is completed.

(c)      Option 3 -
   ---------------

         CLEC will develop service logic using CLEC's Bellcore SPACE platform
         and will transfer the file to NEVADA for testing and deployment. The
         CLEC SPACE platform must be generically compatible with NEVADA'S
         network.

1.3  When CLEC utilizes NEVADA's Local Switching network element and requests

         NEVADA to provision such network element with an AIN trigger which has
         been tested in NEVADA's network, NEVADA will provide access to the
         appropriate
<PAGE>

AIN Call-Related Database residing in NEVADA's SCP for the purpose of invoking
either an unbundled NEVADA AIN feature or a CLEC-developed AIN feature as per
Section 1. 1 above.

 1.4     When CLEC utilizes NEVADA's Resold Exchange Lines and requests NEVADA
         to provision such lines with an AIN trigger which has been tested in
         NEVADA's network, NEVADA will provide access to the appropriate AIN
         Call-Related Database residing in NEVADA's SCP for the purpose of
         invoking a Carrierdeveloped AIN feature as per Section 1. 1.

1.5      When CLEC utilizes its own switch, NEVADA will provide access to the
         appropriate AIN Call-Related Database residing in NEVADA's SCP for the
         purpose of invoking either NEVADA's unbundled AIN feature or a CLEC
         developed AIN feature as per Section 1. 1. CLEC access to NEVADA's AIN
         databases will be via interconnection at NEVADA's regional or NEVADA's
         local STPs consistent with existing network interface specifications
         and using messages conforming with Bellcore's Technical References
         TR-NWT-001284 and TR- NWT-001285. The requirements for these messages
         may be modified by AIN access mediation (specifications not yet
         available).

 1.6     NEVADA will provide access to AIN Call-Related Databases in a
         nondiscriminatory and competitively neutral manner. Any mediation,
         static or dynamic will only provide network reliability, protection,
         security and network management functions consistent with the access
         service provided. Any network management controls found necessary to
         protect the AIN SCP from an overload condition will be applied based on
         non-discriminatory guidelines and procedures. Such management controls
         will be applied to the specific problem source, wherever that source
         is, including NEVADA, and not to all services unless a problem source
         cannot be identified.

 1.7     As requested by CLEC, NEVADA will provide specifications and
         information reasonably necessary for CLEC to utilize NEVADA's SCE as
         provided above.

 1.8     NEVADA will partition and take reasonable steps to protect CLEC service
         logic and data from unauthorized access, execution, or other types of
         compromise, where technically feasible.

 1.9     NEVADA will provide CLEC with access to NEVADA's Service Management
         Systems ("SMS") allowing CLEC to update AIN service data residing in
         NEVADA's AIN network for use on CLEC lines. Access to AIN Service
         Management will be provided via electronic file transfer of CLEC data
         to NEVADA for entry by NEVADA at one of NEVADA's AIN administrative
         terminals as will be used by NEVADA for maintenance of AIN service and
         subscriber data.

APPENDIX DA

DIRECTORY ASSISTANCE SERVICE

This Appendix sets forth the terms and conditions under which Nevada Bell
("NEVADA") agrees to provide nondiscriminatory access to Directory Assistance
Services ("DA Services") to allow CLEC's End User's to obtain telephone numbers.

1.       SERVICES

         NEVADA -will provide the following DA Services:

          1.1     Directory Assistance ("DA")

                  Consists of providing subscriber listing information (name,
                  address, and published telephone number) to CLEC's End Users
                  who dial NPA+555+1212 and whenever appropriate, performing
                  Non-Published service according to current NEVADA methods and
                  practices.

          1.2     Express Call Completion Service ("ECCS")

                  An optional service where available, in which NEVADA completes
                  a call to the requested number on behalf of CLEC's End User,
                  utilizing an automated voice system or with operator
                  assistance. NEVADA agrees to provide DA with ECCS upon request
                  where available.

2.       DEFINITIONS

The following terms are defined as set forth below:

2.1      Non-Published Number

         A telephone number that, at the request of the telephone subscriber, is
         neither published in a telephone directory nor provided by NEVADA's DA
         operator.

2.2      Published Number

         A telephone number that is published in a telephone directory and/or
         listed with directory assistance, and is available upon request by
         calling NEVADA's DA operator.

2.3      Call Branding

         The procedure of identifying a provider's name audibly and distinctly
         to the consumer at the beginning of each DA Services call, and when
         technically feasible, prior to completion of an ECCS request.
<PAGE>

3.       CALL BRANDING AND RATE REFERENCE REQUIREMENTS

3.1      Requirements

         Pursuant to Section 226 (b) of The Telecommunications Act of 1996, each
provider of Operator Services is required to:

               (a)  Provide its brand at the beginning of each telephone call
                    and before the consumer incurs any charge for the call; and

               (b)  Disclose immediately to the consumer, upon request, a quote
                    of its rates or charges for the call.

3.2      Call Brandin

         Currently NEVADA is unable to provide unique branding for CLEC. All DA
         calls will be unbranded. When NEVADA has the capability to uniquely
         brand CLEC DA calls, the Parties shall negotiate the specific price,
         terms and conditions for this service.

3.3      Directory Assistance ("DA") Rate/Reference Information

         Currently, NEVADA is unable to provide unique Rate/Reference
         Information. When NEVADA has the capability to provide unique
         Rate/Reference Information for CLECs, the Parties shall negotiate the
         specific price, terms and conditions for this service. In the interim,
         CLEC-specific rate quotes will only be provided when CLEC's DA Rates
         exactly mirror NEVADA's rates. To the extent CLEC provides NEVADA its
         customer service center number, NEVADA will provide such referral
         number to CLEC's End User customer for all other rate quotes.

4.       RESPONSIBILITIES OF THE PARTIES

4.1      NEVADA will be the sole provider of DA Services for CLECs local serving
         area(s) beginning on the service effective date.
4.2      CLEC will be responsible for providing the equipment and facilities
         necessary for signaling and routing calls with Automatic Number
         Identification ("ANI") to each NEVADA operator switch. Should CLEC seek
         to provide interexchange DA Service under this agreement, it is
         responsible for ordering the necessary facilities through NEVADA's
         intrastate or interstate Access Service tariffs. Nothing in this
         agreement in any way changes the manner in which an interexchange
         carrier obtains access service for the purpose of originating or
         terminating interexchange traffic.

4.3      Except where CLEC is purchasing NEVADA's Unbundled Local Switching
         ("ULS") Port as defined in Appendix UNE, CLEC must separately purchase
         Traffic Operating Position System ("TOPS") Access at a DS-1 level to
         connect its
<PAGE>

               switch to NEVADA's TOPS switch for purposes of delivering
                    Directory Assistance traffic.

4.3.1 NEVADA will provide nondiscriminatory access to Directory Assistance
Services via any of the following methods:

(a)      CLEC provides its own facilities and orders DA hunks and TOPS

         Access from NEVADA;

 (b)     CLEC is collocated in the Wire Center where NEVADA's TOPS switch is
         located and purchases Expanded Interconnection Service Channel
         Termination from NEVADA's tariff FCC 1, Section 18 in addition to the
         TOPS Access and DA hunks; or

(c)      CLEC purchases facilities, DA hunks and TOPS Access from

         NEVADA.

               4.3.2 Rates for TOPS Access are displayed in Appendix PRICING.
                    Rates, terms and conditions for NEVADA's facilities and DA
                    hunks are available per NEVADA's tariff P.S.C.N. C.

         4.3.3 TOPS trunking requirements are described in Appendix ITR.

4.4      Facilities necessary for the provision of DA Services shall be provided
         by the Parties hereto, using standard trunk traffic engineering
         procedures to insure that the objective grade of service is met. Each
         Party shall bear the costs for its own facilities and equipment.

4.5      CLEC will furnish in writing to NEVADA, forty-five (45) days in advance
         of the date when the DA Services are to be undertaken, all End User
         listing records and information required by NEVADA to provide the DA
         Services.

4.6      CLEC will provide NEVADA timely updates to the OS questionnaire when
         changes are necessary. CLEC will send the DA listing records to NEVADA
         via electronic white page gateway as described in Appendix WP.

4.7      NEVADA will accumulate and provide CLEC such data as necessary for CLEC
         to bill its End Users.

5.       METHODS AND PRACTICES

NEVADA will provide the DA Services to CLEC's End Users in accordance with
NEVADA's DA methods and practices that are in effect at the time the DA call is
made, unless otherwise agreed in writing by both Parties.
<PAGE>

6.       PRICING

Pricing for DA Services shall be based on the rates specified in Exhibit I,
which is attached-hereto and made part of this Appendix and Appendix PRICING.
The prices will apply from the service effective date through the term of this
agreement as specified in Section 9.1 below. Beyond the specified term of this
Appendix, NEVADA may change the prices for the provision of DA Services upon one
hundred-twenty (120) days notice to CLEC.

8.       LIABILITY

         The limitation of liability and indemnification provisions of the
         Agreement shall govern performance under this Appendix. CLEC also
         agrees to release, defend, indemnify, and hold harmless NEVADA from any
         claim, demand or suit that asserts any infringement or invasion of
         privacy or confidentiality of any person or persons caused or claimed

provide

         directory assistance ("DA") service to individuals who call NEVADA's DA
         to obtain such information.

1.3      Inasmuch as NEVADA provides DA service under contract for other Local

         Exchange Carriers ("LECs") and Competitive Local Exchange Carriers,
         ("CLECs'~, NEVADA's databases also contain subscriber listing
         information for other LEC and CLEC End Users.

          1.4     Now, therefore, in consideration of these premises, NEVADA and
                  CLEC agree to license to each other certain subscriber listing
                  information contained in each Party's database, under the
                  following terms and conditions:

2.       SERVICE PROVIDED

information

         of their End Users for the book codes listed in Exhibit A.

 2.2     NEVADA shall provide to CLEC published subscriber listing information
         contained in NEVADA's database pertaining to subscribers of all CLECs
         and other LECs that have granted NEVADA written authorization to
         release such subscriber listing information to CLEC.

 2.3     NEVADA currently utilizes manual processes in obtaining and inputting
         subscriber listings of independent Local Exchange Carriers ("LECs")
         into its DA database. CLEC requests for independent LEC subscriber
         listing information will be handled on an individual case basis and
         priced accordingly.
<PAGE>

               2.4  CLEC shall provide NEVADA a minimum of thirty (30) days
                    notice prior to the date when the initial load of listing
                    information is to occur.

3.       USE OF-SUBSCRIBER LISTING INFORMATION

         3.1      CLEC may use the subscriber listing information licensed and
                  provided pursuant to this Appendix for the sole purpose of
                  providing DA services.
         3.2      Upon termination of this Agreement, CLEC shall cease using,
                  for any purpose whatsoever, the subscriber listing information
                  provided hereunder by NEVADA, and shall promptly return such

         The subscriber listing information shall remain the property of NEVADA.
         CLEC shall not sublicense, assign, sell or transfer the subscriber
         listing information licensed hereunder, nor shall CLEC authorize any
         other company or any person to use the subscriber listing information
         for any other purpose. CLEC shall take appropriate measures to guard
         against any unauthorized use of the listings provided to it hereunder
         (at least the same measures it takes to protect its own listings from
         unauthorized use), whether by CLEC, its agents, employees or others.

5.       BREACH OF CONTRACT

In the event a Party is found to have materially breached this Appendix, such
breach shall be remedied immediately and the non-breaching Party shall have the
right to terminate, upon fifteen (15) days notice, until the other Party's
breach is remedied. Further, should CLEC breach this agreement, it shall
immediately cease use of NEVADA's subscriber listing information.

6.       LIABILITY

         consequential, punitive or incidental damages.
<PAGE>

 6.3     CLEC shall indemnify, protect, save harmless and defend NEVADA (or
         NEVADA's officers, employees, agents, assigns and representatives) from
         and against any and all losses, liability, damages and expense arising
         out of any demand, claim, suit or judgment by a third party in any way
         related to NEVADA supplying subscriber listing information, or any
         actual error or omission. CLEC shall so indemnify regardless of whether
         the demand, claim or suit by the third party is brought jointly against
         CLEC and NEVADA, and/or against NEVADA alone. However, if such demand,
         claim or suit specifically alleges that an error or omission appears in
         DA listing information, NEVADA may, at its option, assume and undertake
         its own defense, or assist in the defense of CLEC, in which event CLEC
         shall reimburse NEVADA for reasonable attorneys fees and other expenses
         incurred by it in handling and defending such demand, claim and/or
         suit. CLEC shall not enter into any settlement of any such demand,
         claim or suit without the prior written consent of NEVADA.

7.       TERM OF CONTRACT

This Appendix shall continue in force until terminated by one hundred-twenty
(120) days prior written notice by either Party to the other.

8.       COMPENSATION

CLEC shall compensate NEVADA for the licensing of subscriber listing information
("Directory Listings") as displayed in Appendix PRICING. Each addition,
deletion, or change to the subscriber listing information constitutes an "update
listing", which shall be priced at the same Directory Listings price.

         including name, address and telephone number for inclusion in PACIFIC's
         E91 Database Management System ("'DBMS"). The Automatic Location
         Identification ("ALI") database is created and updated from telephone
         company records by the E91 1 DBMS. This feature is provided by a data
         storage and retrieval system that translates -the telephone number of
         the calling party into the address of the calling party. The ALI
         feature permits display of the address of the calling party at the
         Public Safety Answering Point ("PSAP').

6.2      Responsibilities of the Parties

 6.2.1    CLEC agrees that at a reasonable time prior to establishment of F-911
          Service, CLEC shall download and maintain thereafter all information
          required to establish records necessary for furnishing connection to
          E911 Service and shall promptly notify PACIFIC via PACIFIC's E911 DBMS
          Gateway of any changes to be made to such records. CLEC shall adopt
          and comply with operating methods applicable to downloading and
          maintaining CLEC's End User records in PACIFIC's DBMS, as set forth in
          materials distributed to CLEC by PACIFIC's DBMS Coordinator at the
          time of E91 I establishment.

 6.2.2    PACIFIC shall provide CLEC with a file containing the Master Street
          Address Guide ("MSAG") for the exchanges or communities requested by
          CLEC in accordance with the rate referenced in Section 7 of this
          Appendix.

 6.2.3    PACIFIC will store the names, addresses, and associated telephone
          numbers from CLEC exchanges in the electronic data processing database
          for the E911 DBMS. CLEC is responsible for downloading and updating
          this information to the E911 DBMS Gateway. In addition, PACIFIC shall
          provide CLEC with a statistical report in a timely fashion of CLEC's
          base files downloaded by CLEC to PACIFIC's DBMS, so that CLEC may
          ensure the accuracy of the End User records.

APPENDIX FGA

This Appendix sets forth the terms and conditions under which the Parties will
distribute revenue from the joint provision of Feature Group A ("FGA") Switched
Access Services.

These services will be provided within a Local Access and Transport Area
("LATA"). The Primary Company will compensate the Secondary Company only to the
extent that it has not already been compensated under its interstate or
intrastate access service tariffs or other settlement/contract arrangements.
This Appendix is subject to applicable tariffs.

1.       DEFINITIONS

1.1      Access Minutes or Minutes of Use ("MOUs")

         Those minutes of use as described in Part 69 of the Federal
         Communications Commission's Rules, and are limited to those FGA MOUs
         which terminate in the Secondary Office(s) covered by this Appendix.

1.2      Currently Effective Tariff Rate

         The approved tariff rate effective on the first day of the month for
which compensation is being calculated.

1.3      Feature Group A ("FGA") Switched Access Service

         Includes all facilities and services rendered in furnishing FGA access
         service, LATA wide terminating areas, in accordance with the schedule
         or charges, regulations, terms and conditions stated in the interstate
         or intrastate access service tariffs of the Parties.

1.4      Local Access and Transport Area ("LATA")

         LATA is as defined in the Act.

1.5      Primary Company

         The Party with the Primary Office(s).

1.6      Primary Office

         An office which:

 (a)      directly or jointly connects to an interexchange carrier and/or End
User; and;

 (b) provides joint FGA switched access service to that interexchange carrier
and/or End User with other end offices.
<PAGE>

1.7      Revenues

         Under this Appendix, Revenues are those FGA Switched Access amounts due
         the Primary and Secondary Companies under their applicable tariffs,
         less uncollectible revenues. Revenues for any other services are not
         included. Uncollectible revenues are those revenues the Primary Company
         is unable to collect, using its regular established collection
         procedures. The Primary Company may offset uncollectibles against
         current revenue distribution.

1.8      Secondary Compan

         The Party with the secondary office(s).

1.9      Secondary Offic

         Any office involved in providing joint FGA switched access to an
         interexchange carrier and/or End User through the switching facilities
         of the Primary office.

1.10     Subscriber Access Line

         A communication facility provided under a general and/or exchange
         service tariff extended from a customer premise to a central office
         switch which may be used to make and receive exchange service calls,
         intrastate toll service or interstate toll service calls.

2.       UNDERTAKING OF THE PARTIES

2.1      The Secondary Company will notify the Primary Company of all tariff
         rate revisions affecting this Appendix, which the FCC or other
         appropriate regulatory authority allows to take effect, at least thirty
         (30) days in advance of their effective date. Revenue distribution will
         be based on the revised rates forty-five (45) days after the effective
         date of the tariff revisions. However, if the secondary Company fails
         to notify the Primary Company of a new rate within thirty (30) days of
         its effective date, the Primary company may delay implementation of the
         new rate until the next month's revenue distribution cycle, and will
         not be required to adjust the previous bills retroactively.

         2.2      Each party will furnish to the other such information as may
                  reasonably be required for the administration, computation and
                  distribution of revenue, or otherwise to execute the
                  provisions of this Appendix.

3.       ADMINISTRATION OF REVENUE DISTRIBUTION

The Primary Company will be responsible for the administration, computation and
distribution of the FGA access service revenues collected on behalf of the
Secondary Company.
<PAGE>

4.       MINUTES OF USE ("MOU") DEVELOPMENT

         The Parties will calculate the amount of FGA revenues due each Party,
         by determining the amount of FGA MOUs attributable to each Party as
         described below. The Primary Company will then multiply the MOUs by the
         rates in the Secondary Company's applicable tariff to determine the
         amounts tentatively due to the Secondary Company.

5.       TERMINATING MOU DEVELOPMENT

         5.1      Actual monthly premium (charged at equal access end offices)
                  and non-premium (charged at non-equal access end offices)
                  terminating FGA access MOUs for each office in the LATA will
                  be measured by the Primary Company.
         5.2      Where the Primary Company cannot measure or identify the
                  terminating FGA MOUs by end office, terminating MOUs will be
                  total unmeasured MOUs allocated to the LATA. In this event,
                  those MOUs will be distributed based upon the ratio of each
                  Party's subscriber access lines, as identified in Exhibit A,
                  which is attached hereto and made a part hereof, to the total
                  subscriber access lines in the FGA access area as determined
                  by the Primary Company.

6.       CALCULATION OF REVENUE DISTRIBUTION

6.1      The amount of premium or non-premium revenues due each party each month

         will be equal to the sum of Terminating premium or non-premium revenue
         for each end office. These revenues will be calculated by the Primary
         Company by multiplying each of the Secondary Company's effective
         interstate and/or intrastate FGA switched access tariff rate elements
         (except the Local Transport element described below) by the appropriate
         MOU calculation under Section 5 above.

 6.2     Local Transport (or its equivalent under the Secondary Company's tariff
         and called Transport in this agreement) compensation will be determined
         for each company by multiplying each of the Secondary Company's
         Transport rates by the appropriate MOUs (as calculated under Section 5
         above) by the Secondary Company's percentage ownership of facilities
         agreed on by the Parties and set out in Exhibit A, which is attached
         hereto and made a part hereof.

7.       REVENUE DISTRIBUTION AMOUNTS, MONTHLY STATEMENTS AND

         PAYMENTS

7.1      The Primary Company each month will calculate and prepare a monthly
         compensation statement reflecting the revenue distribution amounts for
         FGA, access service due the Secondary Company.
<PAGE>

7.2      The monthly compensation statement will show, where applicable, for
         each Secondary Office, separately:

(a)      the total number of non-premium or premium terminating MOUs and

         revenue;

(b)      the total compensation due the Secondary Company, by rate element;
(c)      the number of terminating MOUs recorded by the Primary Company;
(d)      the percent ownership factor, if any, used to prorate Local Transport

         revenues; and

(e)      adjustments for uncollectibles.

         7.3      Within sixty (60) calendar days after the end of each billing
                  period, the Primary Company will remit the compensation amount
                  due the Secondary Company. Where more than one compensation
                  amount is due, they may be combined into a single payment.

8.       MISCELLANEOUS PROVISIONS

This Appendix will remain in effect until terminated by thirty (30) calendar
day's notice by either Party to the other.

                                                      (TRUNKING REQUIREMENTS)

This Appendix provides descriptions of the trunking requirements for CLEC and
NEVADA interconnection. The attached scenarios depict the recommended trunk
groups for local, intraLATA toll, interLATA "meet point" and mass calling, E911
and Operator Services Interconnection. All references to incoming and outgoing
trunk groups are from the perspective of CLEC.

1.       LOCAL AND INTRALATA TOLL TRAFFIC

1.1 Tandem Trunking - Single Tandem LATAs
                  Where NEVADA has a single Access Tandem in a LATA, IntraLATA
                  Toll and Local traffic shall be combined on a single Local
                  Interconnection mink group at the tandem for calls destined to
                  or from all End Offices that "home" on NEVADA's tandem. This
                  trunk group shall be two-way and will utilize Signaling System
                  7 ("SS7") signaling.

1.2Direct End Office Trunking
                    The Parties shall establish direct End Office primary high
                    usage Local Interconnection trunk groups for the exchange of
                    IntraLATA Toll and Local traffic where actual or projected
                    traffic demand justifies such a trunk group. These trunk
                    groups shall be two-way and will utilize SS7 signaling.

2.         MEET POINT TRUNKS

         InterLATA traffic shall be transported between CLEC's Central Office
         and NEVADA's Access Tandem over a "Meet Point" Trunk Group separate
         from Local and IntraLATA Toll traffic. The Meet Point Trunk Group will
         be established for the transmission and muting of Switched Access
         traffic between CLEC's End Users and Interexchange Carriers via a
         NEVADA Access Tandem. These trunk groups shall be set up as two-way and
         will utilize SS7 signaling, except multifrequency ("MF') signaling will
         be used on a separate Meet Point Trunk Group to complete originating
         calls to Switched Access customers that use MF FGD signaling protocol.
         (See ITR Scenario #1).

3.         800 (888) TRAFFIC

          3.1       All originating Toll Free Service calls for which CLEC
                    requests that NEVADA perform the Service Switching Point
                    ("SSP") function (e.g., perform the database query) shall be
                    delivered using GR-394 format over the Meet Point Trunk
                    Group. Carrier Code "0110' and Circuit Code of"08" shall be
                    used for all such traffic.
<PAGE>

                    3.2 All post-query Toll Free Service calls for which CLEC
                    performs the SSP function, if delivered to NEVADA, shall be
                    delivered using GR-394 format over the Meet Point Trunk
                    Group for calls destined to IXCs, or shall be delivered by
                    CLEC using GR-317 format over the Local Interconnection
                    Trunk Group for calls dustined to End Offices that directly
                    subtend the tandem.

4.          E911

           A segregated trunk group will be required to interconnect with
           NEVADA's E911 tandem within the exchange in which CLEC offers the
           Exchange Service. This trunk group shall be set up as a one-way
           outgoing only and shall utilize MI: CAMA signaling.

5.         HIGH VOLUME CALL-IN NETWORK

 5.1     A separate High Volume Call In-Local Interconnection ("HVCI-LI") trunk
         group may be provisioned between CLEC's end office(s) and NEVADA's
         LERG- designated High Volume Call-In tandem(s) for each of NEVADA's
         Mass Calling NPA-NXX(s) in a LATA or, alternately, between CLEC's
         tandem and NEVADA's LERG-designated HVCI tandem(s). This HVCI-LI trunk
         group shall be designed and built as one-way (CLEC Central
         Office-to-NEVADA tandem) only and shall use MF signaling. As the
         I-IVCI-IJ trunk group is designed to block all excessive attempts
         toward HVCI/Mass Calling NXXs, it is. necessarily exempt fi-om the one
         percent blocking standard described elsewhere for other final Local
         Interconnection Trunk Groups. It is recommended that this group be
         sized as follows:

              Number of Access Lines Served           Number of ltVCI-LI Trunks.
                                 0 - 10,000                                    2
                            10,000 - 20,000                                    3
                            20,000 - 30,000                                    4
                            30,000 - 40,000                                    5
                            40,000 - 50,000                                    6
                            50,000 - 60,000                                    7
                            60,000 - 75,000                                    8
                                   75,000 +                            9 Maximum

5.2      Ail applicable compensation arrangements described elsewhere-for Local
         Interconnection Trunks/Trunk Groups and terminating access shall apply
         to HVCI-LI Trunks/Trunk Groups and traffic.

               5.3  Should CLEC assign a Mass Calling code and establish an
                    HVCI-LI interface for traffic destined to its HVCI central
                    office(s), CLEC must "home" its HVCI- serving office on a
                    NEVADA HVCI tandem, and a similar HVCI-LI thinking
<PAGE>

                  arrangement (1-way outgoing with MI: signaling) will be
                  provided from NEVADA's tandem to CLEC. In order to allow the
                  parties time to order and install such H-VCI-LI thinks, CLEC
                  must provide NEVADA notification of its intention to deploy
                  Mass Calling code(s) at least ninety (90) days before such
                  crudesx are opened in the LERG.

          5.4     MF and SS7 trunk groups shall not be provided within a DS-1
                  facility; a separate DS-1 per signaling type must be used.
                  Where NEVADA and CLEC both provide ffVCI-LI miniring, both
                  parties' HVCI-LI trunks may ride the same DS-1.

6.       OPERATOR SERVICES

6.1    No Operator Contract - Inward Operator Assistance
         CLEC may choose from two interconnection options for Inward Operator
Assistance as follows:

         6.1.1 Option 1 - Interexchange Carrier ("IXC")
                  CLEC may utilize the Interexchange Carrier Network. CLEC
                  operator will route its calls requiring inward operator
                  assistance through its designareal IXC POP to NEVADA's TOPS
                  tandem. NEVADA shall route its calls requiring inward operator
                  assistance to CLEC's Designated Operator Switch through the
                  designated IXC POP.

         6.1.2    BLV and BLVI inquiries between operator bureaus shall be
                  routed using network-routable access codes published in the
                  LERG over the Local Interconnection Thinks.

 6.2     Operator Contract with NEVADA

          6.2.1   Directory Assistance ("DA")
                  CLEC may contract for DA services only. A segregated tnmk
                  group for these services would be required to NEVADA's TOPS
                  tandem. This trunk group is set up as one-way outgoing only
                  and utilizes MF and Operator Services signaling.

         6.2.2 Express Call Completion Service ("ECCS")
                  CLEC contracting for DA services may also contract for ECCS.
                  This requires a segregated one-way trunk group to NEVADA's
                  TOPS tandem. This trunk group is set up as one-way outgoing
                  only and utilizes MI: signaling.

         6.2.3 Busy Line Verification
                  When NEVADA's operator is under contract to verify CLEC's End
                  User loop, NEVADA will utilize a segregated one-way trunk
                  group with MF signaling from NEVADA's Access Tandem to CLEC
                  switch.
<PAGE>

                  6.2.4 Operator Assistance (0+, 0-)
                           This service requires a one-way trunk group from
                           CLEC's switch to NEVADA's TOPS tandem. This trunk
                           group may carry ECCS calls in addition to OA calls.
                           MF and Operator Services signaling will be required -
                           on the trunk group.

7.       TRUNK DESIGN BLOCKING CRITERIA

A        blocking standard of one half of one percent (.005) during the average
         busy hour, for alternate final trunk groups between the Parties
         networks carrying Meet Point traffic shall be maintained. All other
         direct final trunk groups shall be engineered with a blocking standard
         of one percent (.01).

8.       FORECASTING/SERVICING RESPONSIBILITIES

8.1      Both Parties agree to provide an initial forecast for establishing the
         initial interconnection facilities and equipment. Subsequent forecasts
         will be provided on a semi-annual basis concurrent with the publication
         of NEVADA's General Trunk Forecast including yearly forecasted mink
         quantities for all trunk groups described in this Appendix for a
         minimun of three years, and the use of Common Language Location
         Identifier ("CLLI-MSG") which is described in Bellcore documents
         BR795-100-100 and BR795-400-100.

 8.2     The Parties shall work towards the development of joint forecasting
         responsibilities for traffic utilization over trunk groups. Orders for
         trunks that exceed forecasted quantities for forecasted locations will
         be accommodated as facilities and/or equipment becomes available.
         Parties shall make all reasonable efforts and cooperate in good faith
         to develop alternative solutions to accommodate orders when facilities
         are not available. Intercompany forecast information must be provided
         by the Parties to each other twice a year. The semi-annual forecasts
         shall include:

(a)      yearly forecasted trunk quantities (which include measurements that
         reflect actual tandem Local Interconnection and Meet Point minks, End
         Office Local Interconnection minks, and tandem-subtending Local
         Interconnection end office equivalent trunk requirements) for a minimum
         of three (current and plus-1 and plus-2) years; and

(b)      a description of major network projects anticipated for the following
         six months. Major network projects include romking or network
         rearrangements, shifts in anticipated traffic patterns, orders for
         greater than four (4) DS-ls, or other activities that are reflected by
         a significant increase or decrease in trunking demand for the following
         forecasting period.
<PAGE>

         8.3 If differences in semi-annual forecasts of the Parties vary by more
than 48 additional DS-0 two-way trunks for each Local Interconnection Trunk
Group, the
                    Parties shall meet to reconcile the forecast to within 48
DS-0 trunks.

            8.4     Each Party shall provide a specified point of contact for
                    planning, forecasting and trunk servicing purposes.

9.       TRUNK SERVICING

               9.1  Orders between the Parties to establish, add, change or
                    disconnect thinks shall be processed by using an Access
                    Service Request ("ASR").

   9.2     As discussed in this Appendix, both Parties will jointly manage the
           capacity of Local Interconnection Trunk Groups. Both Parties will
           send a Trunk Group Service Request ("TGSR") to the other Party to
           trigger changes to the Local Interconnection Trunk Groups based on
           capacity assessment. Either Party upon receipt of the TGSR will issue
           an ASR to the other Party:

               (a)  within ten (10) business days after receipt of the TGSR,
                    upon review of and in response to the TGSR received; or

           (b)      at any time as a result of either Party's own capacity
                    management assessment, in order to begin the provisioning
                    process. The intervals used for the provisioning process
                    will be the same as those used for NEVADA's Switched Access
                    service.

 9.3       Orders that comprise a major project shall be submitted at the same
           time, and their implementation shall be jointly planned and
           coordinated. Major projects are those that require the coordination
           and execution of multiple orders or related activities between and
           among NEVADA and CLEC work groups, including but not limited to the
           initial establishment of Local Interconnection or Meet Point trunk
           groups and service in an area, NXX code moves, re-homes, facility
           grooming, or network rearrangements.

           9.3.1  Orders that comprise a major project, i.e., five (5) DS-I's or
                  more, shall be submitted in a timely fashion, and their
                  implementation shall be jointly planned and coordinated.

     9.4 CLEC will be responsible for engineering its network on its side of the
     POI. NEVADA will be responsible for engineering its network on its side of
     the POI.

 9.5     Due dates for the installation of Local Interconnection and Meet Point
         Trunks covered by this Appendix shall be based on NEVADA's intrastate
         Switched Access intervals.
<PAGE>

          9.6                            Trunk serving responsibilities for TOPS
                                         minks used for stand-alone operator
                                         service or Directory Assistance are the
                                         sole responsibility of CLEC.

 10.     SERVICING OBJECTIVE/DATA EXCHANGE
         ---------------------------------

         Each Party agrees to service trunk groups to the foregoing blocking
         criteria in a timely manner when trunk groups exceed measured blocking
         thresholds on an average time consistent busy hour for a twenty
         (20)-business day study period. Upon request, each Party will make
         available to the other trunk group measurement reports for trunk groups
         terminating in the requesting Party's network. These reports will
         contain offered load, measured in CCS (100 call seconds), that has been
         adjusted to consider the effects of overflow, retrials, and day-to-day
         variation. They will also contain overflow CCS associated with the
         offered load, day-to-day variation, peakedness factor, the date of the
         last week in the four-week study period and the number of valid days of
         measurement. These reports shall be made available at a minimum on a
         semi-annual basis upon request.

11. TRUNK FACILITY UNDER UTILIZATION
    --------------------------------

         If a trunk group is under 75 percent (75%) of CCS capacity on a monthly
         average basis, for each month of any six month period, either Party may
         request the issuance of an order to resize the trunk group, which shall
         be left with not less than 25 percent excess capacity. In all cases,
         grade of service objectives identified in Section 7 above shall be
         maintained.

12. NETWORK MANAGEMENT
    ------------------

  12.1   Restrictive Controls
         Either Party may use protective network traffic management controls
         such as 7- digit and 10-digit code gaps on traffic toward each other's
         network, when required, to protect the public switched network from
         congestion due to facility failures, switch congestion, or failure or
         focused overload. CLEC and NEVADA will immediately notify each other of
         any protective control action planned or executed.

12.2     Expansive Controls
         Where the capability exists, originating or terminating traffic
         reroutes may be implemented by either Party to temporarily relieve
         network congestion due to facility failures or abnormal calling
         patterns. Reroutes will not be used to circumvent normal trunk
         servicing. Expansive controls will only be used when mutually agreed to
         by the Parties.

  12.3   Mass Calling
         CLEC and NEVADA shall cooperate and share pre-planning information
         regarding cross-network call-ins expected to generate large or focused
         temporary increases in call volumes.

1.       DESCRIPTION OF SERVICE

Network Component Service ("NCS") is a discretionary offering which NEVADA is
willing to provide under the terms and conditions in this Appendix that are
above and beyond NEVADA's obligations under the Act. Through NCS NEVADA performs
the combining of certain UNEs on behalf of the CLEC for the purpose of the CLEC
providing an end-to-end telecommunications service to end users exclusively
utilizing NEVADA Unbundled Network Elements. Appendix UNE contains a description
of Unbundled Network Elements or, as used herein, "network components" along
with the terms and conditions under which NEVADA will provide Unbundled Network
Elements. NCS will be provided by NEVADA at the prices contained herein. NCS is
market-based priced and is neither subject to me-up nor arbitration. Prices for
NCS that are in addition to the prices for the individual Unbundled Network
Elements are listed in Section 3 of this Appendix.

2.       TERMS AND CONDITIONS

 2.1     The CLEC shall identify on a single NCS order all of the network
         components, all associated ordering codes (as determined by NEVADA),
         and the sequence in which NEVADA is to combine those elements on behalf
         of CLEC. When this order involves only NEVADA's network, the order will
         be for Network Component Service (NCS), even though the individual
         element types are to be derived from Appendix UNE.

 2.2     In addition to the recurring and non-recurring charges for the
         individual Unbundled Network Elements ordered, the Network Component
         Service will be priced as described in section 3 of this Appendix.

 2.3     Any changes or rearrangements of the components shall constitute a new
         NCS offering and applicable non-recurring and service order charges
         apply.

 2.4     The network components provided by NEVADA under the provision of this
         Appendix shall remain the property of NEVADA.

 2.5     Provisioning of NCS under this Appendix may be accomplished over such
         routes, technologies, and facilities as NEVADA may elect as long as the
         connection being requested by the CLEC is functional.

               2.6  NEVADA is responsible only for the installation, operations
                    and maintenance of the NCS originally defined and ordered by
                    the CLEC. NEVADA is not
<PAGE>

responsible for the Telecommunication Services provided by the CLEC through the
use of NCS. 2.7 X~here NCS is provided to CLEC and it is dedicated to a single
end user, if NCS is for any reason disconnected, the individual network
components shall be made available to NEVADA for future provisioning needs,
unless NCS is disconnected in error.
2.8 Network elements identified through the Bona Fide Request process will not
be provisioned under this Appendix.
3. PRICING
3.1 For each NCS arrangement, the CLEC shall pay the full recurring and non
recurring rate per Unbundled Network Element, feature, function, or ancillary
charge as shown in Appendix PRICING plus the additional NCS recurring and
nonrecurring market-based rates, as shown in Section 3.2.
3.2 The prices for providing NCS for NEVADA LINExxs are as follows:

          3.3 This Appendix is available as a package offering. Any changes to
          prices, terms and conditions of UNEs offered pursuant to Appendix LINE
          shall not be incorporated into this Appendix without the mutual
          agreement of the Parties.

          3.4 Since this offering is discretionary and not subject to the Act,
          any prices set by NEVADA to provide NCS, even if zero (or no charge),
          are fully at NEVADA's discretion. The prices for NCS are subject to
          change.

4. GENERAL RESPONSIBILITIES OF THE PARTIES
4.1 Each Party is solely responsible for the services it provides to its end
users and to other Telecommunications Carriers.
<PAGE>

 4.2       The Parties shall work cooperatively to minimize fraud associated
           with third-number billed calls, calling card calls, and any other
           services related to this Agreement.

 4.3     At all times during the term of an Agreement, executed pursuant to this
         STC, each Party shall keep and maintain in force at each Party's
         expense all insurance required by law (e.g. workers' compensation
         insurance) as well as general liability insurance for personal injury
         or death to any one person, property damage resulting from any one
         incident, automobile liability with coverage for bodily injury for
         property damage. Upon request from the other Party, each Party shall
         provide to the other Party evidence of such insurance (which may be
         provided through a program of self insurance).

4.4      Unless otherwise stated, NEVADA will render a monthly bill to CLEC for
         service(s) provided hereunder. Remittance in full will be due within
         thirty (30) days of that billing date. Interest shall apply on overdue
         amounts at the highest rate allowed by applicable law.

 4.5     For purposes of pre-order, ordering, provisioning, maintenance and
         billing, CLEC will use the same processes, as used in connection with
         Unbundled Network Elements obtained through Appendix UNE.

APPENDIX NETWORK INTERCONNECTION METHODS ("NIM')

Network Interconnection Architecture designates Network Interconnection Methods
("NIMs") to be used by the Parties. These include: Fiber Meets; Virtual
Collocation Interconnection; Physical Collocation Interconnection; leasing of
NEVADA facilities; and other methods as mutually agreed to by the Parties.

1.         HBER MEETS

1.1      Where the Parties interconnect their networks pursuant to a Fiber Meet,
         the Parties shall jointly engineer and operate such interconnection as
         a single SONET transmission system for the purposes of terminating
         calls intended for a End User of one of the Parties, Transit Traffic,
         and jointly provided Exchange Access. The Parties agree to establish
         technical interface specifications for Fiber-Meet arrangements that
         permit the successful interconnection and completion of traffic routed
         over the facilities that interconnect at the Fiber Meet. Each Party is
         responsible for designing, provisioning, ownership, and maintenance of
         equipment and facilities on its side of the POI. Each Party is free to
         select the manufacturer of its Fiber Optic Terminal ("FOT"). Neither
         Party will be allowed to access the Data Communications Channel ("DCC')
         of the other Party's EOT. The technical specifications will be designed
         so that each Party may, as far as is technically feasible,
         independently select the transmission, multiplexing, and fiber
         terminating equipment to be used on its side of the Fiber Meet. The
         Parties will work cooperatively to achieve equipment compatibility.
         Requirements for such interconnection specifications will be defined in
         joint engineering planning sessions between the Parties. The Parties
         will use good faith efforts to develop and agree on these
         specifications within ninety (90) days of the determination by the
         Parties that such specifications shall be implemented, and in any case,
         prior to the establishment of any Fiber Meet arrangements between them.

               1.2  NEVADA shall, wholly at its own expense, procure, install,
                    and maintain the agreed-upon Optical Line Terminating
                    Multiplexer ("OLTM") equipment in each NEVADA Wire Center
                    where the Parties establish a Fiber Meet in capacity
                    sufficient to provision and maintain all logical trunk
                    groups prescribed by Appendix 1TR, Sections 1 and 2. CLEC
                    shall, wholly at its own expense, procure, install and
                    maintain the agreed upon OLTM equipment in each CLEC Wire
                    Center where the Parties establish a Fiber Meet in capacity
                    sufficient to provision and maintain all logical trunk
                    groups prescribed by Appendix ITK, Sections 1 and 2.

1.3NEVADA shall designate a manhole or other suitable entry way immediately
                  outside the Wire Center as a Fiber Meet entry point and shall
                     make all necessary preparations to receive and to allow and
                     enable CLEC to deliver fiber optic
<PAGE>

                  facilities into that manhole with sufficient spare length to
                  reach the OLTM equipment in NEVADA's Wire Center. CLEC shall
                  deliver and maintain such strands wholly at its own expense.

          1.4     CLEC shall designate a manhole or other suitable entry way
                  immediately outside CLEC's Wire Center as a Fiber Meet entry
                  point and shall make all necessary preparations to receive and
                  to allow and enable NEVADA to deliver fiber optic facilities
                  into that manhole with sufficient spare length to reach the
                  OLTM equipment in CLEC's Wire Center. NEVADA shall deliver and
                  maintain such strands wholly at its own expense.

2.   AVOIDANCE OF OVER PROVISIONING Underutilization is the inefficient
     deployment and use of the network due to forecasting a need for more
     capacity than actual usage requires and results in unnecessary costs for
     interconnection facilities. To avoid over provisioning, the Parties will
     agree to joint facility growth planning as detailed below.


3.         JOINT FACILITY GROWTH PLANNING

The initial interconnection facility deployed for each interconnection shall be
the smallest standard available, e.g., for SONET this is an OC-3 system. The
following lists the criteria and processes needed to satisfy additional capacity
requirements beyond the initial system.

3.1 Criteria

           3.1.1  Investment is to be minimized.
           3.1.2  Facilities are to be deployed in a "just-in-time" fashion.
3.1.3Facilities will be planned for in accordance with the trunk forecasts
                  exchanged between the Parties as described in Appendix ITR.

3.2 Processes

3.2.1    Discussions to provide relief to existing facilities will be triggered
         when either Party recognizes that the overall system facility ("DS-Is")
         is at 90% of capacity.

3.2.2    Both Parties will perform a joint validation to ensure interconnecting
         facilities have not been over provisioned. If any systems are over
         provisioned, they will be turned down as appropriate. If any
         interconnecting-facilities resizing lowers the fill level of the
<PAGE>

         interconnecting facilities below 90%, the growth planning process will
         be suspended and will not be reinitiated until a 90% fill level is
         achieved. Trunk design blocking criteria described in Appendix ITR will
         be used in - determining trunk group sizing requirements
and forecasts.

 3.2.3   If based on the forecasted equivalent DS-1 growth the existing fiber
         optic system is not projected to exhaust within one year, the Parties
         will suspend further relief planning on this interconnection until a
         date one year prior to the projected exhaust date. If growth patterns
         change during the suspension period, either Party may re-initiate the
         joint planning process.

3.2.4    If the placement of a minimum size system will not provide adequate
         augmentation capacity for the joint forecast over a two-year period and
         the forecast appears reasonable based upon history, the next larger
         system may be deployed. In the case of a SONET system, the OC-3 system
         could be upgraded to an OC-12. If the forecast does not justify a move
         to the next larger system, another minimal size system (such as on
         OC-3) could be placed. This criteria assumes both Parties have adequate
         fibers for either scenario. If adequate fibers do not exist, both
         Parties would negotiate placement of additional fibers and/or
         equipment.

 3.2.5   Both Parties will negotiate a project service date and corresponding
         work schedule to consmet relief facilities in an effort to achieve
         "just-in-time" deployment.

3.2.6 The joint planning process/negotiations should be completed within two
months of identification of 90% fill.

4.         VIRTUAL COLLOCATION INTERCONNECTION

 4.1     Subject to space availability and technical feasibility, NEVADA will
         provide Virtual Collocation in accordance with the Act, the FCC rules
         promulgated thereunder (e.g., 47 C.F.R. ss. 51.323), and any Commission
         decision. Unless inconsistent with this Section 4, Virtual Collocation
         Interconnection will be provided as set forth in Nevada Bell's
         interstate Virtual Collocation tariffs (Nevada Bell's Tariff FCC No.
         1).

               4.1.1 If CLEC designates permitted telecommunications equipment
                    for Virtual Collocation that is not set forth in Nevada
                    Bell's ("NEVADA's") interstate tariff, the provisioning of
                    such telecommunications equipment shall be handled in the
                    same manner as is used by NEVADA for provisioning non-
                    tariffed equipment under its interstate Virtual Collocation
                    tariffs; provided, however, that in no event shall NEVADA be
                    required to file any tariff, whether interstate or
                    intrastate in jurisdiction. By way of example and not
<PAGE>

                  limitation, CLEC would apply for, and NEVADA would price,
                  provide, and bill such telecommunications equipment as if
                  under Nevada Bell's interstate virtual collocation tariff.

 4.2     When providing Virtual Collocation, NEVADA will, at a minimum, install,
         maintain, and repair Virtual Collocation equipment for CLEC within the
         same time periods and with failure rates that are no greater than those
         that apply to the performance of similar functions for comparable
         equipment of NEVADA.

               4.3  NEVADA will provide Virtual Collocation in "Eligible
                    Structures", as defined in Appendix PHYSICAL COLLOCATION,
                    and permit the Virtual Collocation of telecommunications
                    equipment permitted by 47 U.S.C.ss.251(c) (6), FCC roles
                    promulgated thereunder (e.g., 47 C.F.R.ss.51.323), and
                    Commission decisions.

4.3.1Notwithstanding any other provision hereof, NEVADA is under no
                  obligation to provide and shall not provide Virtual
                  Collocation for any equipment that, by its nature or due to
                  its characteristics and methods of operation, interferes with
                  or impairs service over NEVADA's network equipment, or
                  facilities, or the network, equipment, or facilities of any
                  other person or entity; creates hazards for or cause damage to
                  those networks, equipment, or facilities, the Premises, or the
                  Eligible Structure; impairs the privacy of any communications
                  carded in, fi:om, or through the Eligible Structure; or
                  creates hazards or cause physical harm to any person, entity,
                  or the public. The terms "Premises' and "Eligible Structure"
                  are as defined in Appendix PHYSICAL COLLOCATION.

4.4      Unless otherwise agreed to by NEVADA or required by law, the
         telecommunications equipment that is permitted in any Eligible
         Structure for Virtual Collocation is limited to the same or
         substantially similar telecommunications equipment (determined with
         reference to power and environmental requirements and conditions) that
         NEVADA already places in that particular Eligible Structure (determined
         on an Eligible Structure-by-Eligible Structure basis, and not by class
         of Eligible Structures). To the extent that permitted Virtual
         Collocation equipment is not the same or substantially similar, the
         preparation of the Eligible Structure (e.g., power, environmental) for
         the Vimmi Collocation equipment will be charged to CLEC on an ICB
         basis.

               4.5Unless otherwise agreed to by NEVADA or required by law, all
                    Virtual Collocation equipment shall comply with Bellcore
                    Network Equipment Building System (NEBS) Generic
                    Requirements (GR-63-CORE and GR-1089-CORE) and any successor
                    document(s), including as such may be modified at any time
                    and from time to time and such modifications are adopted and
                    followed by NEVADA, and then where and how adopted and
                    followed by NEVADA ("NEBS Standards"). To the extent that
                    permitted Virtual Collocation equipment does not
<PAGE>

         meet the NEBS Standards, the preparation of the Eligible Structure for
         placement of such non-compliant Virtual Collocation equipment (e.g.,
         firewall construction), if any, will be charged to CLEC on an ICB
         basis.

4.6Virtual Collocation provided hereunder is made available subject to and in
         accordance with:

         (a)      Nevada Bell's Technical Publication for Expanded
                  Interconnection with Nevada Bell - Virtual Collocation & SBI
                  dated October, 1995, and any successor document(s), as may be
                  modified from time to time as set forth below ("Virtual
                  Collocation Technical Publication"). NEVADA concurs in the
                  Virtual Collocation Technical Publication (ignoring any
                  provisions that are applicable only to SONET-Based
                  Interconnection) and adopts it as its own and, therefore, for
                  purposes of this Appendix, any reference therein to Nevada
                  Bell shall be deemed to refer to NEVADA only.

         Co)      any statutory and/or regulatory requirements in effect at the
                  time of the submission of the Virtual Collocation application
                  or subsequently become effective and then when effective.

         CLEC shall strictly observe and abide by each.

 4.7     The Virtual Collocation Technical Publication is attached hereto and,
         along with the NEBS Standards, are incorporated herein by this
         reference. CLEC may obtain a copy of the NEBS Standards by contacting
         Bell Communications Research, Inc. at 1-800--421-2674.

 4.8     If the Virtual Collocation Technical Publication is modified from the
attached, the
         following shall apply:.

               (a)  If a modification is made alter the date on which CLEC has
                    or orders a Virtual Collocation arrangement, NEVADA shall
                    provide CLEC with those modifications or with revised
                    versions of such, listing or noting the modifications as
                    appropriate. Any such modification shall become effective
                    and thereafter applicable under this Agreement thirty (30)
                    days after such amendment is released by NEVADA, except for
                    those specific amendments to which CLEC objects to within
                    thirty (30) days of receipt, providing therewith an
                    explanation for each such objection. The Parties shall
                    pursue such objections informally with each other and, if
                    not resolved within forty-five (45) days, either Party will
                    have fourteen (14) days to invoke the dispute resolution
                    procedures applicable to this Agreement. If neither Party
                    invokes those procedures, the modification is deemed
                    effective and applicable.
<PAGE>

(b)  If a modification is made after this Appendix becomes pan of an effective
     "Statement of Terms and Conditions" or similar document for NEVADA (and the
     modification has not been included in a change to that - "Statement" or
     this Appendix), and before CLEC's initial virtual collocation arrangement,
     then NEVADA will provide CLEC with a copy of such modifications or the most
     recent version or revision of the particular document promptly after
     receipt of CLEC's virtual collocation application. Any CLEC objection to
     those modifications must be received by NEVADA by the thirtieth (30th) day
     after receipt by CLEC. Thereafter, the same process and procedure
     (including timelines) for resolving any objection made under Section 4.8(a)
     shall apply.

(c)      Notwithstanding Sections 4.8(a) and/or (b), any modification made to
         address situations potentially harmful to NEVADA's or another's
         network, equipment, or facilities, the Eligible Structure, the
         Premises, or to comply with statutory or regulatory requirements shall
         become effective immediately and shall not be subject to objection.
         NEVADA will immediately notify CLEC of any such modification.

 4.9     The terms and conditions expressly set forth in this Appendix shall
         control in the event of an irreconcilable conflict with the Virtual
         Collocation Technical Publication or the NEBS Standards (including any
         modification to any of them that can be objected to under this Section
         4.8, regardless of whether CLEC objected to such modification pursuant
         to Section 4.8). Notwithstanding the immediately preceding,
         modifications that are governed by Section 4.8(c) shall apply
         regardless of any conflict or inconsistency with any other term or
         condition governing a Virtual Collocation arrangement unless contrary
         to law.

  4.10   Sections 14.3, 14.4, and 14.6 of Appendix PHYSICAL COLLOCATION are
         incorporated by this reference into this Appendix NIM for purposes of
         virtual collocation.

5.         PHYSICAL COLLOCATION INTERCONNECTION

          NEVADA will provide Physical Collocation in accordance with the Act,
          the FCC rules promulgated thereunder (e.g., 47 C.F.R. ss.51.323), any
          Commission decision and subject to Appendix PHYSICAL COLLOCATION.

6.       LEASING OF NEVADA'S FACILITIES

 6.1     CLEC's leasing of NEVADA's facilities for purposes of Appendix FrR,
         Sections 1 and 2: Network Interconnection Architecture will be subject
         to the mutual agreement of the Parties.
<PAGE>

 6.2     CLEC's leasing of NEVADA's facilities for purposes of Section 4.3 of
         the Main Agreement: Network Interconnection Methods, will be subject to
         the mutual agreement of the Parties.

6.3      CLEC will provide a written leased facility request that will specify
         the A- and Z-ends (CLLI codes, where known), equipment and muxing
         required and provide quantities requested. Requests for leasing of
         NEVADA's facilities for the purposes of interconnection and any future
         augmentations are subject to facility availability at the time of the
         request.

 6.4     Any request by the CLEC for leased facilities where facilities,
         equipment, or riser cable do not exist will be considered, and NEVADA
         may agree to provide under a Leased Facilities Bona Fide Request
         ("BFR") Process as defined below:

          6.4.1   A Leased Facilities BFR will be submitted by CLEC in writing
                  and will include a description of the facilities needed
                  including the quantity, size (DS-3 or DS-l), A- and Z-end of
                  the facilities, equipment and muxing requirements, and date
                  needed.


          6.4.2   The CLEC may cancel a Leased Facilities BFR at any time, but
                  will pay NEVADA any reasonable and demonstrable costs of
                  processing and/or implementing the Leased Facilities BFR up to
                  the date of cancellation.

          6.4.3   Within ten (10) business days of its receipt, NEVADA will
                  acknowledge receipt of the Leased Facilities BFR.

         6.4.4    Except under extraordinary circumstances, within thirty (30)
                  days of its receipt of a Leased Facilities BFR, NEVADA will
                  provide to CLEC a written response to the request. The
                  response will confirm whether NEVADA will offer the leased
                  facilities or not. If NEVADA determines it will offer the
                  leased facilities, NEVADA will provide the CLEC a Leased
                  Facilities BFR quote which will include the applicable
                  recurring and nonrecurring rates and installation intervals.

         6.4.5    Within sixty-five (65) business days of its receipt of the
                  Leased Facilities BFR quote, CLEC must confirm its order. If
                  not confirmed within sixty-five (65) business days, NEVADA
                  reserves the fight to modify or withdraw its Leased Facilities
                  BFR quote.

1.       INTERI~ NUMBER PORTABILITY ("INP")
         ----------------------------------

         1.1 General
                  NEVADA and CLEC will provide Interim Number Portability
                  ("INP") in accordance with requirements of the Act. INP will
                  be provided by each Party to the other upon request. INP will
                  be provided with minimum impairment of functionality, quality,
                  reliability and convenience to subscribers of CLEC or NEVADA.
                  As described herein, INP is a service arrangement whereby an
                  End User,, who switches subscription of exchange service from
                  one provider to another is permitted to retain, for its use,
                  the existing assigned number provided that the End. User
                  remains in the same serving wire center.

          1.2     Terms, Conditions Under Which NEVADA Shall Provide INP
                  1.2.1 Service Provided

1.2.1.1 NEVADA shall only provide INP, as described herein, to CLEC.

1.2.1.2  NEVADA shall only provide INP services and facilities where technically
         feasible, subject to the availability of facilities, and only from
         properly equipped central offices. NEVADA does not offer INP services
         and facilities for NXX codes 555, 800, 888, 950 or any NXX codes that
         are not specific to a geographic location and wire center.

1.2.1.3  NEVADA shall not provide INP services for End User accounts where the
         End User's payments are thirty (30) days or more in arrears, or where
         contract termination liabilities would be assessed by NEVADA to the End
         User, unless full payment is made, or an agreement is reached where
         CLEC agrees to make full payment on the End User's behalf, including
         any termination amounts due.

1.2.1.4  When the exchange service offerings associated with INP service are
         provisioned using DNCF switching arrangements, NEVADA shall, for
         technical reasons, provide service - from host central offices. INP
         service for remote arrangements will be served from the host central
         office.
<PAGE>

 1.2-2   Obligations of NEVADA
         NEVADA's sole responsibility is to comply with the service requests it
         receives from CLEC and to provide INP in accordance with this
-        Appendix.

1.2.3    Obligations of CLECs

 1.2.3.1   CLEC shall coordinate the provision of service with NEVADA to assure
           that CLEC's switch is capable of accepting INP ported traffic.

1.2.3.2 CLEC is solely responsible to provide equipment and facilities that are
     compatible with NEVADA's service parameters, interfaces, equipment and
     facilities. CLEC shall provide sufficient terminating facilities and
     services at the terminating end of an INP call to adequately handle all
     traffic to that location and shall ensure that its facilities, equipment
     and services do not interfere with or impair any facility, equipment or
     service of NEVADA or any of its End Users. In the event that NEVADA
     determines, in its sole judgment, that CLEC will likely impair or is
     impairing, or interfering with any equipment, facility, or service of
     NEVADA or any of its End Users, NEVADA may either refuse to provide INP
     service or terminate it in accordance with other provisions of this
     Agreement or NEVADA's tariffs, where applicable.

1.2.3.3  CLEC shall provide an appropriate intercept announcement service for
         any telephone numbers subscribed to INP service for which CLEC is not
         presently providing exchange service or terminating to an End User.

1.2.3.4  When a ported telephone number becomes vacant, e.g., the telephone
         number is no longer in service by the original End User and a period
         for intercept and referral equivalent to that which is provided by
         NEVADA to its own End User subscribers has elapsed, the ported
         telephone number will be released back to NEVADA.

1.2.3.4.1Formerly ported telephone numbers which revert to NEVADA as described
         above shall be reassigned or provided with a standard NEVADA intercept
         announcement in accordance with NEVADA's standard operating procedures
         then in effect.
<PAGE>

               1.2.3.5 CLEC shall designate to NEVADA at the time of its initial
                    service request for INP service one of the following options
                    for handling and processing of Calling Card, Collect, Third
                    Party, - and other operator handled non-sent paid calls from
                    or to CLEC assigned telephone numbers:

                               (a)      CLEC may elect to block the completion
                                        of third number and calling card calls
                                        through the use of LIDB to select ported
                                        numbers.

                             Co)     For non-sent paid calls billed to INP
                                     assigned numbers, a separate
                                     sub-clearinghouse billing arrangement must
                                     be established which will provide for the
                                     transmission of the ElYIR 01-01-01 billing
                                     records, and settlement of toll revenues.

         1.2.4 Limitations Of Service

                  1.2.4.1  NEVADA is not responsible for adverse effects on any
                           service, facility or equipment from the use of IN'P
                           service.

                  1.2.4.2  End-to-end transmission characteristics cannot be
                           specified by NEVADA for calls over INP facilities
                           because end-to-end transmission characteristics may
                           vary depending on the distance and routing necessary
                           to complete calls over INP facilities and the fact
                           that another carder is involved in the provisioning
                           of service.

 1.3     Service Descriptions

         1.3.1 INP - DNCF
                  INP-DNCF is a service whereby a call dialed to an INP-DNCF
                  equipped telephone number, assigned to NEVADA, is
                  automatically forwarded to CLEC-assigned, 7- or 10-digit
                  telephone number. The forwarded-to-number must be specified by
                  CLEC at the same wire center wherein the ported number
                  resides.

                    1.3.1.1  INP-DNCF provides an initial call path and one
                             additional path for the forwarding of no more than
                             two (2) simultaneous calls to CLEC's specified
                             forwarded-to number. Additional call paths are
                             available on a per path basis up to a maximum of
                             ninety-nine (99) call paths.
<PAGE>

          1.3.1.2 CLEC-assigned forwarded-to number shall be treated as two
          separate calls with respect to interconnection compensation, End User
          toll billing, and intercompany settlement and access billing, i.e., an
          incoming call to NEVADA's ported number shall be handled like any
          other NEVADA call being terminated to that End Office and the ported
          call to CLEC's assigned telephone number in CLEC's switch shall be
          handled as any local calls between NEVADA and CLEC.

          1.3.1.3 Where facilities exist, NEVADA will provide identification of
          the originating telephone number, via SS7 signaling, to CLEC.

1.3.2 INP - FlexDID'

         INP-FlexDID is a service which provides for the delivery of the called
         (dialed) number to CLEC's switching (central office or premises)
         equipment for identification and subsequent routing and call completion
         over a dedicated direct final trunk group.

          1.3-2.1 R%TP-FlexDD:) is available either on a per voice grade channel
          basis or a per DS-1 (24 equivalent voice grade channels) basis.

          1.3.2.1.1 Where the location of CLEC's switching equipment to which
          NEVADA is providing voice grade or DS- I INP-FlexDID service resides
          outside the exchange or central office serving area from which the
          INP-FlexDID service is purchased, CLEC shall pay applicable
          interoffice mileage charges as specified in NEVADA's Tariff P.S.C.N.
          C, Section 7.

          1.3.2.2 INP-FlexDID service must be established with a minimum
          configuration of two (2) voice grade channels and one unassigned
          telephone number per NEVADA switch. Transport facilities arranged for
          INP-FlexDID may not be mixed with any other type of trunk group.
          Outgoing calls may not be placed over facilities arranged for
          INP-FlexDID service.

               1.3.2.3 SS7 Signaling is not available on the INP-FlexDID
                    facilities.

1.4      Interco any Terminating Compensation

         With regard to the division of intercompany compensation and switched
         access revenues associated with interim number portability, the Porting
         Party shall pay the Ported-to-Party $1.75 per month for each business
         line and $1.25 per month for each residence line associated with the
         INP arrangement. Determination of the number of lines to which the
         above payment shall apply will be made at the time
<PAGE>

the INP arrangement is established. Such payment shall continue until the INP
arrangement is disconnected or PNP is made available for the INP number,
whichever occurs first. Such amount is in consideration of the Switched Access
compensation and reciprocal compensation that would have been received by each
Party if PNP had been in effect.

1.5      Pricin

          1.5.1 The Parties will comply with all effective FCC, Commission
          and/or court orders governing INP cost recovery and compensation. The
          Parties acknowledge that the Telephone Number Portability Order is
          subject to pending Petitions for Reconsideration and may be appealed.
          As such, the Number Portability Order may be reconsidered, revised and
          remanded, or vacated, subject to further proceedings before the FCC.
          As such, until a final decision is rendered on INP cost recovery, the
          Parties agree to track the costs associated with the implementation
          and provision of INP and to "true-up" INP-related accruals to reflect
          the final terms of any such order.

          1.5.2 Neither Party waives its rights to advocate its views on INP
          cost recovery, or to present its views before any appropriate
          regulatory agency.

          1.5.3 Charges associated with the Provision of INP are described in
          Appendix PRICING.

2.       PERMANENT NUMBER PORTABILITY ("PNP")

         2.1      General

                  The FCCs Telephone Number Portability, CC Docket No. 95-116,
                  First Memorandum Opinion and Order on Reconsideration, 12 FCC
                  Rcd. 7236 (1997), requires " . . all LECs to implement a long
                  term service provider portability method in the 100 largest
                  Metropolitan Statistical Areas ("MSA") according to a phased
                  schedule that commences October 1, 1997, and concludes
                  December 31, 1998." While the FCC declined " . . . (to]
                  choose[s] a particular technology for providing number
                  portability", it did establish performance criteria that LECs
                  must meet. The technology that meets the FCC's performance
                  criteria is Location Routing Number ("LRN"). LRN is currently
                  being used by the telecommunications industry to provide PNP.

         2.2      Terms and Conditions Under Which NEVADA Shall Provide PNP

2.2.1 Service Provided

2.2. 1.1 NEVADA will provide CLEC the use of NEVADA's PNP

            database via the Service Provider Number Portability ("SPNP")
<PAGE>

Database Query. CLEC's STP, Tandem, and/or End Office's LRN software will
determine the need for accessing NEVADA's PNP database, and triggers the query.
NEVADA's PNP database will determine if the number has, or has not, been ported
and will provide LRN if a number is ported.

          2.2.1.2 NEVADA will provide CLEC the use of th NEVADA PNP database,
          PNP software, and SS7 network via the SPNP Query.

          2.2.1.3 NEVADA shall only provide PNP services and facilities where
          technically feasible, subject to the availability of facilities, and
          only from properly equipped central offices.

          conditions.

2.2.4 Obligations of Both Parties

          2.2.4.1 When a ported telephone number becomes vacant, e.g., the
          telephone number is no longer in service by the original End User, the
          ported telephone number will be released back to the carrier owning
          the switch in which the telephone number's NXX is native.

          2.2.4.2 Each Party has the right to block a default routed call
          entering a network in order to protect the public switched network
          from overload, congestion, or failure propagation.

          2.2.4.3 Industry guidelines shall be followed regarding all aspects of
          porting numbers from one network to another.

          2.2.4.4 Intracompany testing shall be performed prior t scheduling of
          intercompany testing.

          2.2.4.5 Each Party shall designate a single point of contact ("SPOC")
          to schedule and perform required testing. These tests will be
<PAGE>

           performed during a mutually agreed upon time frame and must meet the
           criteria set forth by the Pacific West Region for porting.

          2.2.4.6 Each Party shall abide by NANC and Pacific West Region

2.2.5 Limitations Of Service

          2.2.5.1 Telephone numbers can be ported only within NEVADA wire
          centers as approved by the State Commission.

          2.2.5.2 Telephone numbers in the following NEVADA NXXs shall not be
          ported:

(a) wireless NXXs.

          2.2.5.3 Telephone numbers with NXXs dedicated to High Volume Call In
          ("HVCI") networks are not portable via LRN. HVCI numbers will be
          ported as described in Section 4 of this Appendix.

2.2.6 Service Descriptions

          2.2.6.1 The switch's LRN software determines if the called party is in
          a portable NXX. If the called party is in a portable NXX, a query is
          launched to the PNP database to determine whether or not the called
          number is ported.

          2.2.6.2 When the called number with a portable NXX is ported, an LRN
          is returned to the switch that launched the query. Per industry
          standards, the LRN appears in the CdPN ("Called Party Number") field
          of the SS7 message and the called number then appears in the GAP
          ("Generic Address Parameters") field.

          2.2.6.3 When the called number with a portable NXX is not ported, the
          call is completed as in the pre-PNP environment.

          2.2.6.4 The FCI ("Forward Call Identifier") field's entry is changed
          from 0 to 1 by the switch triggering the query when a query is made,
          regardless of whether the called number is ported or not.
<PAGE>

          2.2.6.5 The N- I carrier (N carrier is the responsible Party for
          terminating a call to the End User) has the responsibility to
          determine if a query is required, to launch the query, and to route
          the call to the switch or network in which the telephone number
          resides.

          2.2.6.6 If CLEC chooses not to fulfill their N-1 carrie
          responsibility, NEVADA will perform queries on calls to telephone
          numbers with portable NXXs received from the N- I carrier and route
          the call to the switch or network in which the telephone number
          resides.

          2.2.6.7 CLEC shall be responsible for payment of charge to NEVADA for
          any queries made on the N-1 carrier's behalf

2.2.7 Pricing

         The price of PNP queries shall be the same as those in the FCC No. 1

         Access Services Tariff, Section 19.

3.       INP TO PNP TRANSITION

          3.1 NEVADA will deploy LRN in the switches requested as a result of
          the State Commission's poll of CLECs to name the switches in which
          they want LRN deployed.

          3.2 CLECs shall issue LSRs to change their existing INP accounts to
          PNP within a 90 day window for all the selected switches in an MSA
          which starts immediately after the PNP Phase completes for that MSA,
          e.g., for all selected switches in the Los Angeles MSA the window
          starts 7/19/98 and completes 10/17/98.

          3.3 New requests for INP will not be provided in a NEVADA switch once
          LRN has been deployed in that switch.

          3.4 The Parties shall coordinate each MSA's transition from INP to
          PNP. When a service provider's INP lines exceed eight (8) in an NXX
          and/or fifty (50) lines in a MSA, they shall send advance notice to
          the owner of the switch(es) in which those TNs are homed, indicating
          the volume of orders involved in the INP to PNP transition.

4.       MASS CALLING CODES

4.1      General

         Mass calling codes, i.e., High Volume Call-In ("HVCI") NXXs, are used
         in a network serving arrangement provided by NEVADA in special
         circumstances
<PAGE>

where large numbers of incoming calls are solicited by an End User and the
number of calls far exceeds the switching capacity of the terminating office,
the number of lines available for terminating those calls, and/or the STP's
query capacity to the PNP database. The following two different sets of End User
objectives usually create this condition:

(a)      low call completion; and

(b)      high call completion.

Given the potentially hazardous effect calling conditions of this nature could
have on the network, NEVADA will provide mass calling code portability using a
non-LRN solution.

4.2      Service Provided

          4.2.1 NEVADA will offer the ability to port telephone numbers with a
          mass calling NXX code via the use of pseudo codes or route index
          numbers. In this non-LRN scenario, calls to the NEVADA mass calling
          NXX code will leave the originating end office over dedicated NT trunk
          groups to the NEVADA mass calling tandem. The mass calling tandem will
          then route the calls over dedicated MF trunks to the NEVADA HVCI
          serving office. The HVCI serving office will translate the dialed mass
          calling number to a non-dialable pseudo code or a route index number
          that mutes the call to the mass calling customer.

          4.2.2 When a CLEC requests that a NEVADA number with a mass calling
          NXX code be ported to their network, NEVADA will build translations at
          the HVCI serving office to route the incoming calls to a CLEC provided
          dedicated Direct Inward Dial (DID) MY trunk group from the HVCI
          serving office to the CLEC central office.

4.3      Obligations of NEVADA

          4.3.1 NEVADA will port its numbers with mass calling NXXS upon request
          by the CLEC. Non-LRN porting will be done via pseudo code or route
          index translation in the NEVADA HVCI serving office rather than STP
          queries to the PNP database. This method of porting mass call numbers
          will be used during both INP and PNP period in each market.

          4.3.2 NEVADA will not charge the CLEC for the use of its HVCI network
          by the CLEC's mass calling customer. In exchange, NEVADA will not pay
          intercompany terminating compensation for terminating minutes of use
          (MOU) for ported HVCI calls.
<PAGE>

4.4      Obligations of CLEC

4.4.1 CLEC shall adhere to NEVADA's Local Service Request (LSR) format and mass
calling due date intervals.

               4.4.2 The CLEC shall provide the facility and DID trunk group
                    from the NEVADA HVCI serving office to the CLEC's serving
                    office. The CLEC shall size this one-way MF trunk group.

               4.4.3 The CLEC shall forego any inter-company terminating MOU
                    compensation for termination calls coming in on this trunk
                    group.

4.5      CLEC Mass Calling Codes

               4.5.1 Should the CLEC assign a mass calling NXX code(s) and
                    establish a mass calling interface for traffic destined to
                    its HVCI serving office(s), the CLEC shall home its HVCI
                    serving office(s) on a NEVADA mass calling tandem and a
                    similar mass calling trunking arrangement (one-way outgoing
                    with MF signaling) will be provided from NEVADA's tandem to
                    the CLEC. In order to allow the Parties time to order and
                    install such mass calling trunks, the CLEC shall provide
                    NEVADA notification of its intention to deploy mass calling
                    NXX code(s) at least 90 days before such codes are opened in
                    the LERG. See Appendix ITR for more information regarding
                    this mass local interconnection trunk group.

               4.5.2 MF and SS7 trunk groups shall not be provided within a DS1
                    facility. A separate DS1 facility per signaling type shall
                    be used. Where NEVADA and CLEC both provide mass calling
                    trunking, both Parties' mass calling trunks may ride the
                    same DS I facility.

4.6      Limitations of Service

               CLEC shall adhere to NEVADA's reserved number terms and
                    conditions. When a ported number with a mass calling NXX
                    code becomes vacant, e.g., the ported number is no longer in
                    service by the original end user, the ported number shall be
                    released back to the carrier owning the switch in which the
                    telephone number's NXX is native.

5.       PROVISION OF INP AND PNP BY CLEC TO NEVADA

CLEC shall provide INP and PNP to NEVADA under no less favorable terms and
conditions as when NEVADA provides such services to CLEC.

                      PERMANENT NUMBER PORTABILITY ("PNP")
                        BONA FIDE REQUEST ("BFR") PROCESS

The Permanent Number Portability ("PNP") Bona Fide Request ("BFR") is a process
which Competitive Local Exchange Carriers ("CLECs") shall use to request that
PNP be deployed:

     (a) in a Metropolitan Statistical Area ("MSA") beyond the 100 largest MSAs
in the country, and

(b)  in additional switch(es) in an MSA in which PNP has been deployed. Per the
     FCC's First Report And Order And Further Notice Of Proposed Rulemaking
     (July, 1996, paragraph 80), CLEC can request that PNP be deployed in
     additional MSAs beginning January 1, 1999. NEVADA is to provide PNP in that
     MSA in the requested switches within six (6) months of receipt of a BFR.

Per the FCC's First Memorandum Opinion And Order On Reconsideration (March,
1997, 165,66), switches that were not requested to be PNP capable in the initial
PNP deployment in the top 100 MSAs can be requested to be made PNP capable. The
following time frames begin after an MSA's phase end date has been reached:

(a)      equipped DNCF switches within 30 days

(b)      hardware capable switches within 60 days

(c)      capable switches requiring hardware within 180 days

(d)      non-capable switches within 180 days

These time frames begin after the receipt of a BFR.
<PAGE>

ATTACHMENT 1

REQUEST FOR INSTALLATION OF PNP SOFTWARE

The request to make one or more switches in an MSA PNP capable shall be made in
the form of a letter from CLEC to its NEVADA Account Manager which shall specify
the following:

(a)      the MSA in which requested switch(es) are located;

(b)      the- switch(es), by CLLI code, that are to become PNP capable;

(c)  the date when PNP capability is requested with the FCC established time
     frames being the least amount of time; and

(d)  the projected quantity of queries that result from this new capability with
     a demand forecast per Tandem or End Office with which CLEC interconnects.

An initial response from NEVADA's Account Manager, acknowledging receipt of the
BFR and the date when requested switch(es) will be PNP capable, must be made to
CLEC within ten (10) business days of receipt of the BFR.

OPERATOR SERVICES

This Appendix sets forth the terms and conditions under which Nevada Bell
("NEVADA") agrees to provide nondiscriminatory access to Operator Services for
CLEC.

1.       SERVICES

NEVADA will provide the following Operator Services:

1.1      Fully Automated Call Processing

         Allows the caller to complete a call utilizing equipment without the
         assistance of NEVADA's operator, hereafter called "Operator."

                  This allows the caller the option of inputting calling card
                  numbers using the Mechanized Calling Card Service ("MCCS").

          1.2     Operator-Assisted Call Processing

                  Allows the caller to complete a call by receiving assistance
from an Operator.

2.       DEFINITIONS

2.1      Fully Automated Call Processin

         NEVADA will support the following fully automated call types for CLEC:

         2.1.1 Fully Automated Calling Card Station-To-Station

                  This service is provided when the caller dials zero ("0'% plus
                  the desired telephone number and the telecommunications
                  calling card number to which the call is to be charged. The
                  call is completed without the assistance of an Operator. An
                  authorized telecommunications calling card for the purpose of
                  this Appendix is one for which NEVADA can perform billing
                  validation. Fully- Automated Calling Card Call Service may
                  also include the following situations:

               (a)  When an individual with a disability dials zero ("0") and
                    identifies himself or herself as disabled, he or she will
                    provide the Operator the desired telephone number and the
                    calling card number to which the call is to be billed.


               (b)  When due to trouble-on the network, or lack of service
                    components (facilities to the MCCS network), the automated
                    call processing cannot be completed without assistance from
                    an Operator.
<PAGE>

               (c)  When an Operator reestablishes an interrupted call that
                    meets any

                           of the situations described in this call type.

2.2      Operator-Assisted Call Processin

         NEVADA will support the following operator-assisted call types for
CLEC:

         2.2.1    Semi-Automated Station-To-Station

                  A service provided when the caller dials zero ("0") plus the
                  telephone number desired and the call is completed with the
                  assistance of an Operator. Semi-Automated Station-to-Station
                  service may also include the following situations:

          (a)     Where the caller does not dial zero ("0") prior to calling the

                  number desired from a public or semi-public telephone, or from
                  a telephone where the call is routed directly to an Operator
                  (excluding calling card calls).

               (b)  When an Operator re-establishes an interrupted call that
                    meets any

                  of the situations described in this call type.

2.2.2    Semi-Automated Person-To-Person

         A service in which the caller dials zero ("0") plus the telephone
         number desired and specifies to the Operator the particular person to
         be reached or a particular PBX station, department or office to be
         reached through a PBX attendant. This service applies even if the
         caller agrees, after the connection is established, to speak to any
         party other than the party previously specified. Semi- Automated
         Person-to- Person service may also include:

(a)      Where the caller does not dial a zero ("0") prior to dialing the

         number from a public or semi-public telephone, or where the call is
         routed directly to an Operator.

               (b)  When an operator reestablishes an interrupted call that
                    meets any

                  of the situations described in this call type.

2.2.3 Semi-Automated Calling Card Station-To-Station

         A service provided when the caller dials zero ("0") plus the desired
         telephone number and provides the Operator the calling card number to
         which the call is to be charged. Semi-Automated Calling Card
         Station-toStation service may also include the following situations:
<PAGE>

(a)      When the caller does not dial zero ("0") prior to dialing the number

         desired from a public or semi-public telephone, or from a telephone
         that is directly routed to an Operator, and the call is billed to a
         calling card.

               (b)  When an Operator reestablishes an interrupted call that
                    meets any

                   of the situations described in this call type.

2.2.4 Station-To-Station ("Operator Handled")

         A service provided when the caller dials zero ("0") and places a sent
         paid, collect, third number or calling card station-to-station call
         using an Operator's assistance. These calls may originate from a
         private, public or semi-public telephone. The service may also include
         the situation when an Operator reestablishes an interrupted call that
         meets any of the situations described in this call type.

2.2.5 Person-To-Person ("Operator Handled")

         A service in which the caller dials zero ("0") and specifies to the
         Operator the number desired and the person to be reached, or a
         particular PBX station, department or office to be reached through a
         PBX attendant. The call remains a person-to-person call even if the
         caller agrees, after the connection is established, to speak to any
         party other than the party previously specified. The service may also
         include situations when an Operator reestablishes an interrupted call
         that meets any of the situations described in this call type.

2.2.6 Line Status Verification

         A service in which the caller asks the Operator to determine the
condition of a telephone line.

2.2.7 Busy Line Interrupt

         A service in which the caller asks the Operator to interrupt a
         conversation in progress, to determine if one of the parties is willing
         to speak to the caller requesting the interrupt. A Busy Line Interrupt
         charge will apply even if no conversation is in progress at the time of
         the interrupt attempt, or when the parties interrupted refuse to
         terminate the conversation in progress.

2.2.8 Miscellaneous

         Includes the following call types: General Assistance 800, 888 and
         connections to all other Toll Free services, CLEC Repair Bureau and
         Business Office requests, credit requests, NPA-NXX location requests,
         and all other 0- No Attempt services.
<PAGE>

3.       CALL BRANDING AND RATE REFERENCE REQUIREMENTS

3.1      Requirements

         Pursuant to Section 226 (b) of The Telecommunications Act of 1996, each
         provider of Operator Services is required to:

          (a) provide its brand at the beginning of each telephone call and
          before the consumer incurs any charge for the call; and (b) disclose
          immediately to the consumer, upon request, a quote of its rates or
          charges for the call.

          3.2      Call Brandin

                  Currently NEVADA is unable to provide unique branding for
                  CLEC. All OS calls will be unbranded. When NEVADA has the
                  capability to uniquely brand CLEC's OS calls, the Parties
                  shall negotiate the specific price, terms and conditions for
                  this service.

          3.3      Operator Services ("OS") Rate/Reference Information

                   Currently, NEVADA is unable to provide unique Rate/Reference
Information.

                  When NEVADA has the capability to provide unique
                  Rate/Reference Information for CLECs, the Parties shall
                  negotiate the specific price, terms and conditions for this
                  service. In the interim, CLEC specific rate quotes will only
                  be provided when CLEC's OS Rates exactly mirror NEVADA rates.
                  To the extent CLEC provides NEVADA its customer service center
                  number, NEVADA will provide such referral number to CLEC's End
                  User customer for all other rate quotes.

4.       HANDLING OF EMERGENCY CALLS TO OPERATOR

         To the extent CLEC's NXX encompasses multiple emergency agencies,
         NEVADA will agree to query the caller on his/her community and to
         transfer the caller to the appropriate emergency agency for the
         caller's area. CLEC must provide NEVADA with the correct information to
         enable the transfer. CLEC will also provide default emergency agency
         numbers to use when the customer is unable to provide his/her
         community. When the assistance of another Carrier's operator is
         required, NEVADA will attempt to reach the appropriate operator if the
         network facilities for inward assistance exist. CLEC agrees to
         indemnify NEVADA for any misdirected calls.

5.       RESPONSIBILITIES OF THE PARTIES

          5.1 NEVADA will be the sole provider of Operator Services fo CLEC's
          local service area(s) beginning on the service effective date. NEVADA
          will provide Operator Services only where the necessary physical
          facilities are available and in place and under conditions previously
          stated in this Appendix.
<PAGE>

          5.2 CLEC will be responsible for providing the equipment and
          facilities necessary for signaling and routing calls with Automatic
          Number Identification ("ANI") to each NEVADA operator switch. Should
          CLEC seek to provide interexchange Operator Services under this
          agreement, it is responsible for ordering the necessary facilities
          through NEVADA's interstate or intrastate Access Service tariffs.
          Nothing in this agreement in any way changes the manner in which an
          interexchange carrier obtains access service for the purpose of
          originating or terminating interexchange traffic.

          5.3 Except where CLEC is purchasing Unbundled Local Switchin ("ULS")
          Port as defined in Appendix UNE, CLEC must separately purchase TOPS
          Access at a DS-1 level to connect its switch to NEVADA's TOPS switch
          for purposes of delivering operator traffic. 5.3.1 NEVADA will provide
          nondiscriminatory access to Operator Services via any of the following
          methods

          (a) CLEC provides its own facilities and orders OS trunks and TOPS

                  Access from NEVADA;

(b)      CLEC is collocated in the Wire Center where NEVADA's TOPS

         switch is located and purchases Expanded Interconnection Service
         Channel Termination from NEVADA's tariff FCC 1, Section 18 in addition

                           APPENDIX OSS-RESALE & UNE
<PAGE>

                ACCESS TO OPERATIONS SUPPORT SYSTEMS FUNCTIONS

1.       General Conditions

          1.1 This Appendix sets forth the terms and conditions under which
NEVADA provides nondiscriminatory access to NEVADA'S operations support systems
(OSS) "functions" to CLEC for pre- ordering, ordering, provisioning, maintenance
/ repair, and billing. NEVADA has established performance measurements to
illustrate non-discriminatory access. These measurements are represented in
Appendix Performance Measurements.

          1.2 Resale and Unbundled Network Elements (UNE) functions, will be
accessible via electronic interface, as described herein, where such functions
are available. Manual access is available for all pre-ordering, ordering,
provisioning, and billing functions via the Local Service Center (LSC). Repair
and maintenance functions are available in a manual mode through the Local
Operations Center (LOC).

          1.3 CLEC agrees to utilize NEVADA electronic interfaces, as described
herein , only for the purposes of establishing and maintaining Resale services
or UNEs through NEVADA. In addition, CLEC agrees that such use will comply with
the summary of SBC's security practices as attached on the user ID request form.
Failure to comply with such security guidelines may result in forfeiture of
electronic access to OSS functionality.

          1.4 CLEC's access to pre-order functions described in 2.2.2 and 2.3.2
will only be used to view Customer Proprietary Network Information (CPNI) of
another carrier's end-user where CLEC has obtained an authorization for release
of CPNI from the end user and has obtained an authorization to become the end
user's local service provider. The authorization for release of CPNI must
substantially reflect the following:

                   1.4.1 "This written consent serves as instruction to all
holders of my local exchange telecommunications Customer Proprietary Network
Information (CPNI) and account identification information to provide such
information to the undersigned. Specifically, I authorize disclosure of my
account billing name, billing address, and directory listing information, and
CPNI, including, service address, service and feature subscription, long
distance carrier identity, and all pending service order activity. This
Authorization remains in effect until such time that I revoke it directly or
appoint another individual/company with such capacity or undersigned receives
notice to disconnect my local exchange service or notice that a service
disconnect has been performed. At and from such time, this Authorization is null
and void."

Or

                   1.4.2 Authorization for change in local exchange service and
release of CPNI with documentation that adheres to all requirements of state and
federal law, as applicable.
<PAGE>

               1.5  By utilizing electronic interfaces to access OSS functions,
                    CLEC agrees to

perform accurate and correct ordering as it relates to the application of Resale
rates and charges where they are subject to the terms of this Interconnection
Agreement and applicable NEVADA tariffs, and CLEC agrees to perform accurate and
correct ordering as it relates to NEVADA UNE rates and charges per the terms of
this Interconnection Agreement. All exception handling must be requested
manually from the LSC.

          1.6 In areas where Resale and UNE. order functions are not available
via an electronic interface for the pre-order, ordering and provisioning
processes, NEVADA and CLEC will use manual processes. Should NEVADA develop
electronic interfaces for these functions for itself, NEVADA will make
electronic access available to CLEC.

          1.7 The Information Services (I.S.) Call Center will provide technical
support function for electronic interfaces. CLEC will also provide a single
point of contact for technical issues related to the electronic interfaces.

          1.8 NEVADA and CLEC will establish interface contingency plans and
disaster recovery plans for the pre-order, ordering and provisioning of Resale
services and UNE.

          1.9 NEVADA reserves the right to modify or discontinue the use of any
          system or interface as it deems appropriate. Provided however,

(a) NEVADA shall provide CLEC with at least 90 days prior written notice of any
planned discontinuance and provide CLEC with a functionally equivalent interface
to access the OSS functions for any system or interface that is discontinued.
Upon CLEC request, NEVADA shall also provide a reasonable transition period.

(b) NEVADA shall provide CLEC with reasonable prior written notice of any
significant system modifications.

          1.10 If CLEC elects to utilize electronic interfaces based upon
industry guidelines for Resale or UNE, NEVADA and CLEC agree to participate in
the Order and Billing Forum (OBF) and the Telecommunications Industry Forum
(TCIF) to establish and conform to uniform industry guidelines for electronic
interfaces for pre- order, ordering, and provisioning. Neither Party waives its
rights as participants in such forums or in the implementation of the
guidelines. To achieve system functionality as quickly as possible, the Parties
acknowledge that NEVADA may deploy these interfaces with requirements developed
in advance of industry guidelines. Thus, subsequent modifications may be
necessary to comply with emerging guidelines. CLEC and NEVADA are individually
responsible for evaluating the risk of developing their respective systems in
advance of guidelines and agree to support their own system modifications to
comply with new requirements. In addition, NEVADA has the right to define LSR
Usage requirements according to the General Section 1.0, paragraph 1.4 of the
practices in the OBF Local Service Ordering Guidelines (LSOG), which states:
"Options described in this practice may not be
<PAGE>

applicable to individual providers tariffs; therefore, use of either the field
or valid entries within the field is based on the providers tariffs/practices."

          1.11 Due to enhancements and on-going development of access to the
functionalities of NEVADA'S OSS, certain interfaces described in this Appendix
may be modified, temporarily unavailable or may be phased out after execution of
this Appendix. In compliance with section 1.9 of this Appendix, NEVADA agrees
that interfaces phased out will be accompanied with proper notice. For those
interfaces that are not available at time of execution, but which will become
available after signature of this Appendix, NEVADA will provide CLEC notice of
when such interfaces will be available.

          1.12 CLEC is responsible for obtaining operating system software and
hardware to access OSS functions as specified in the document "Requirements for
Access to Nevada Bell OSS Functions."

scheduled training class.

         7.6 CLEC agrees that CLEC personnel attending classes are to utilize
only training databases and training presented to them in class. Attempts to
access any other NEVADA or SBC system are strictly prohibited.
<PAGE>

         7.7 CLEC further agrees that training material, manuals and instructor
guides 'Can be duplicated only for use internally for the purpose of training
employees to utilize capabilities of NEVADA's OSSs in accordance with this
Appendix.

8.       Rates

         8.1 Not forgoing the PUC of Nevada's ability to establish costing and
pricing rules for access to OSS, NEVADA and CLEC agree on the following terms in
establishment of OSS rates for access to NEVADA's OSS functions. CLEC will pay
NEVADA the OSS rate(s) that will be established within 14 calendar days from the
date NEVADA OSS rates are set forth in California Public Utilities Commission's
first rulemaking in the Open Access and Network Architecture Development (OANAD)
proceeding. Should an OSS rate(s) not be established in OANAD by September 30,
1998, CLEC will pay NEVADA the OSS rate(s) that NEVADA determine* (within 14
days) but that are based upon the methodology NEVADA uses to propose rate(s) in
OANAD. Such rates paid will be subject to true-up should the final outcome of
OANAD establish a different rate methodology. Should the PUC of Nevada set forth
a proceeding that will establish OSS rates, the terms of the section will be
modified to reflect the final outcome of such proceeding. This rate waiver is
expressly for access to OSS functions, and not applicable to any other product,
unless expressly documented in this Agreement. Neither party waives its rights
pursuant to OSS or any other product in the OANAD proceeding, nor rights in any
other product cost proceeding.

9.       Effective Date

         9.1 Whereas CLEC is currently operational under an existing, approved
Interconnection Agreement, this Appendix OSS will be effective, pending
commission approval, 10 days after it is filed with the state commission.
Alternatively, this Appendix will be effective upon approval by the state
commission when it is approved as a part of the Interconnection Agreement.

APPENDIX

Performance Measures
<PAGE>

1.0      Introduction

The parties agree that the measurements set forth in this appendix, if met by
Nevada Bell, illustrate non- discriminatory access to Nevada Bell's Operations
Support Systems (OSS) and cover the five recognized OSS functions (Pre-Ordering,
Ordering, Provisioning, Maintenance and Repair, and Billing).

The performance measures contained herein, notwithstanding any provisions in any
other appendix in this Agreement, are not intended to create, modify or
otherwise affect parties' rights and obligations. The existence of any
particular performance measure, or the language describing that measure, is not
evidence that CLEC is entitled to any particular manner of access, that these
measures relate solely to access to OSS, or is it evidence that Nevada Bell's
obligations are limited to providing any particular manner of access. The
parties' rights and obligations to such access are defined elsewhere, including
the relevant laws, FCC and NPUC decisions/regulations, tariffs, and
interconnection agreements.

The Performance Measures, Remedies Plan, related auditing and review procedures
contained herein are subject to modification by final decisions of the
Commission and subsequent approval by Nevada Bell.

2.0       Reservation of Rights

By agreeing to the performance measures contained in this agreement, Nevada
Bell:

          o does not make any admission regarding the propriety or
          reasonableness of the NPUC establishing performance penalties;

          o reserves the right to contest the level of disaggregatio for purpose
          of assessing penalties by the NPUC;

          o reserves the right to contend that any resulting penalties
          established by the NPUC should be viewed as liquidated damages and as
          the exclusive remedy for any failure of performance; and,

          o does not admit that an apparent less-than-parity condition reflects
          discriminatory treatment without further factual analysis.

3.0      Reporting Process

Performance reports will be made available to the CLEC by the fifteenth calendar
day of the month succeeding the reporting period (calendar month, unless
otherwise noted). If the fifteenth falls on a weekend or holiday, the reports
will be made available the next business day. Positive reporting will be done
for all measures, even those reported on an exception only basis.

CLEC will have access to monthly reports through an interactive website to
include individual CLEC data, aggregate CLEC data, and Nevada Bell's data.
<PAGE>

4.0      Auditing

CLEC and Nevada Bell will consult with one another and attempt in good faith to
resolve any issues regarding the accuracy or integrity of data collected,
generated, and reported pursuant to this Appendix. In the event that CLEC
requests such consultation and the issues raised by CLEC have not been resolved
within 30 days after CLEC's request for consultation, then Nevada Bell will
allow CLEC to commence a mini-audit, at CLEC's expense, upon providing Nevada
Bell 5 days advance written notice (including e-mail).

CLEC may not request more than five (5) mini-audits of performance measures
during the year and is limited to auditing five (5) single measures during the
year. CLEC will pay for the miniaudits, including Nevada Bell's reasonable
associated costs and expenses, unless Nevada Bell is found to be misreporting or
misrepresenting data or to have non-compliant procedures, in which case, Nevada
Bell will pay for the mini-audit, including CLEC reasonable associated costs and
expenses. If during the mini-audit of individual measures, more than 50% of the
measures in a major service category are found to have flawed data or reporting
problems, the entire service category will be re-audited at the expense of
Nevada Bell. The major service categories are listed below:

                              o  Pre-Ordering

                              o  Ordering

                              o  Provisioning

                              o Maintenance

                              o  Network Performance

                              o  Billing

                              o  Database Updates

                              o Collocation

                              o  Interfaces

In addition to the mini-audits, Nevada Bell will perform an annual comprehensive
of Nevada Bell's reporting procedures and reportable data. This audit will be
performed on behalf of the aggregate of CLECs and performed by independent
auditors. The cost of the annual audit will be shared between CLEC and Nevada
Bell.

5.0      Review Procedures

The parties agree that as experience is acquired with Performance Measures and
underlying business processes, parties will learn which measures set forth in
Section 9.0 have not been properly defined or are more or less useful than
others. Parties also agree that experience will show whether new measures are
needed or whether certain existing measures are not needed or require
modification. Accordingly, the parties agree to review the effectiveness of and
modifications to the Performance Measures in February 2000. In the event parties
cannot agree on any addition, deletion or modification, parties will jointly
submit such dispute for resolution by the NPUC.
<PAGE>

If, prior to the agreed-upon review date, there is consensus that one or more
measures are not effective, Parties will meet to discuss modifying the
measure(s) or process(es). If there is no consensus, the individual Party
seeking formal review by the NPUC shall give notice to the other Party of its
intent to do so. The Party will also describe the action it intends to take and
the reason(s) for its proposed actions.

6.0      Performance Remedies Plan

This section sets forth the terms and conditions by which Nevada Bell will pay
CLEC liquidated damages in the event Nevada Bell fails to meet specified
performance measures. The Parties agree and acknowledge that a) the Liquidated
Damages are not a penalty and have been determined based upon the facts and
circumstances known to the Parties at the time of the negotiation and entering
into of this Agreement, with due consideration given to the performance
expectations of each Party; b) the Liquidated Damages constitute a reasonable
approximation of the damages the CLEC would sustain if its damages were readily
ascertainable.

6.1      Sole Remedy

These liquidated damages shall be the sole and exclusive monetary remedy of CLEC
for Nevada Bell's failure to meet specified performance measures and shall be in
lieu of any other damages CLEC might otherwise seek for such breach through any
claim or suit brought under any contract or tariff.

6.2      Payments/Credits

Payments/credits are made directly to the CLEC. Nevada Bell's obligations to
provide nondiscriminatory access to its operations support systems, under the
Act and under the interconnection agreements, is to the CLEC. Accordingly,
payments/credits for out of parity performance will be made to the CLEC in the
form of liquidated damages.

6.3      Sample Size

Liquidated damages only apply to those measures where the sample is large enough
to provide a valid statistical comparison. The minimum sample size is 20
occurrences per submeasure/measure per month.

6.4      Commencement Of Remedies

None of the liquidated damages provisions set forth in this Agreement will apply
during the first three months after CLEC purchases the type of service or
unbundled network elements(s) associated with a particular performance measure.
<PAGE>

6.5      Review Period

Should performance payments be reviewed with performance measures by the NPUC,
the Parties agree to meet and negotiate any changes required to bring this
agreement into compliance with any recommendations for changes made by the NPUC.

6.6      Parity Submeasures

Generally, the measures and submeasures contained in this Appendix specify
parity with Nevada Bell performance (i.e., performance equal to that which
Nevada Bell achieves for itself) as the Performance Criterion. Performance on a
single measure or submeasure that is 1.65 standard deviations below-the level of
service that Nevada Bell provides to itself constitutes a failure. An increased
performance remedy is imposed when the out of parity condition remains in this
range for three consecutive months ("chronic" occurrence), or when the out of
parity condition is more than three standard deviations below the level of
Nevada Bell's performance for itself (a "severe" miss).

For a chronic miss (three consecutive months) or severe miss (greater than three
standard deviations), the amount of the remedy will triple for a one month miss
greater than 1.65 or 2.36 standard deviations. In other words, in the third
month, Nevada Bell will pay twice that amount to the CLEC.

6.7      Benchmark Submeasures

For certain measures/submeasures, a specific quantitative target has been
adopted. Nevada Bell will pay for any occurrences beyond the acceptable level in
the benchmark. The chronic and severity elements analogous to those set forth
for the parity measures are also applicable.
<PAGE>

  6.8      Remedies Plan

  The table below sets forth the parameters for the specific criteria under
  which performance remedies will be imposed on Nevada Bell.

          Degree of Deviation 1 month 3 consecutive months 1.65(lesser than)
          S.D. plus or minus 2.36 for $125. $3750 parity submeasures (0 LT
          occurrences LT or equal to 5% for benchmark submeasures) 2.36 LT SD LT
          or equal to 3.0 for parity $375 $3750 submeasures (5% LT occurrences
          LT or equal to 10% for benchmark submeasures) GT 3 S.D. for parity
          $625 $3750 submeasures (GT 10% for benchmark submeasureel .1 1 1 1

Payments/credits are based on the number of submeasures that were out of parity
(i.e., greater than 1.65 standard deviations or those submeasures below the
benchmark) for the given submeasure, and escalated by a factor of three for
chronic and severe problems. Nevada Bell will receive a "forgiveness" every six
months, for each submeasure, which Nevada Bell can use to offset a missed
submeasure.
<PAGE>

Limitations

Nevada Bell receives one forgiveness each 6 months per submeasure. Subject to
the additional limitations below, the forgiveness must be used at the first
available opportunity.
A forgiveness cannot be used immediately after a missed month. A forgiveness
cannot be used to offset a chronic (a miss three or more consecutive months) or
severe (a miss of more than 3 standard deviations) miss. A forgiveness cannot be
applied to other than the submeasure to which it is originally assigned.
Nevada Bell cannot accrue (hold) more than two forgiveness units, at any one
time, for any given submeasure.

6.9      Procedural Cap

If the total liquidated damages amounts computed within one month for all CLECs
exceeds $100,000, an expedited hearing will be held to determine whether the
amounts exceeding $100,000 should be paid by Nevada Bell. The amounts owed up to
$100,000 will be prorated and paid to CLEC. Nevada Bell will be required to make
the payments/credits in excess of $100,000 only if a preponderance of the
evidence shows that Nevada Bell engaged in negligent or intentional misconduct
and that CLEC suffered substantial competitive harm.

7.0      Exceptions

In no event will Nevada Bell be liable to pay liquidated damages if Nevada
Bell's failure to meet or exceed any of the specified measures is caused,
directly or indirectly, by a Delaying Event. A "Delaying Event" 'means; a) a
failure by the CLEC to perform any of its obligations set forth in this
Agreement; b) any delay, act or failure to act by an end user, agent or
subcontractor of either Party-, c) any force majeure event; d) for Out of
Service Repairs for unbundled loops, where either Party lacks automatic testing
capability, or e) situations where Nevada Bell's failure to meet any of the
specified measures is beyond the control of Nevada Bell for other reasons. If a
Delaying Event (i) prevents Nevada Bell from performing a specified measure,
then such specified measure will be excluded from the calculation of liquidated
damage, or (H) only suspends Nevada Bell's ability to timely perform the
specified measure, the applicable time frame in which Nevada Bell's compliance
with the performance criteria is measured will be extended on an hour-for-hour
or day-for-day basis, as applicable, equal to the duration of the Delaying
Event.

The most obvious of such exceptions would include items such as force majeure
events, situations where the CLEC is at fault for the apparent less-than-parity
performance result, or situations where such result is beyond the control of
Nevada Bell for other reasons.

In addition, there will be situations where the process is really in parity but
inherent limitations in the performance measures suggest an out of parity
condition. Nevada Bell will conduct a factual analysis on those atypical
situations and present the results of such analysis to CLEC within 30
<PAGE>

days of presenting the performance results containing the apparent out of parity
condition to CLEC to show the apparent less-than-parity performance result is
not the result of discriminatory treatment.

  Nevada Bell will also be relieved from payment of remedies for failures on
  certain performance measures associated with Pre-Ordering, Ordering,
  Provisioning, , Network Performance, Billing, Database Updates, Collocation,
  and Interfaces, that are affected by the CLEC's failure to provide accurate
  and timely forecasts. CLEC must forecast product volumes within 20% of actual
  results and submit orders without discrepancies for 80% of its orders. Order
  accuracy will be used to offset any amounts owed by Nevada Bell under this
  remedies plan.

APPENDIX PHYSICAL COLLOCATION

1.       GENERAL OFFERING

1.1      This Appendix sets forth the descriptions and requirements for Physical

         Collocation that NEVADA offers and will provide to CLEC under this
         Agreement.

          1.2 Except where Physical Collocation is not practical for technical
          reasons or

         because of space limitations, NEVADA will provide Physical Collocation
         to CLEC in accordance with this Appendix for the purposes of
         interconnection to NEVADA pursuant to 47 U.S.C. Section 251(c)(2) and
         for obtaining access to NEVADA's unbundled network elements pursuant to
         47 U.S.C. Section 251(c)(3). Physical Collocation shall be provided on
         a non-discriminatory basis, on a "first come, first-served" basis, and
         otherwise in accordance with the requirements of the Act (including 47
         U.S.C. Section 25 1 (c)(6)), and applicable FCC rules thereunder.

     1.3 Unless contrary to the terms and conditions contained in this Appendix,
the terms

         and conditions of this Agreement are incorporated herein by this
         reference and shall apply as if set forth herein.

2.       DEFINITIONS

2.1      CLEC Telecom Equipment

         The telecommunications equipment and ancillary telecommunications
         facilities that the CLEC is permitted to and does place in the Premises
         as allowed by this Appendix. "CLEC Telecom Equipment" includes
         telecommunications equipment necessary for interconnection to NEVADA or
         access to its unbundled network elements in accordance with the Act,
         applicable FCC rules, and paragraphs 579-582 of the FCC's First Report
         and Order, FCC 96-325, 11 FCC Rcd 15499 (1996) ("First Interconnection
         Order'). Such telecommunications equipment includes but is not limited
         to:

(a)      transmission equipment, such as optical terminating equipment and

         multiplexers;

          (b) equipment for the termination of basic transmission facilities
          pursuant to

         47 C.F.R. Sections 64.1401 and 64.1402 as of August 1, 1996;
         and

(c)      such additional telecommunications equipment that may be agreed to by

         NEVADA and CLEC, or designated in future FCC or Commission decisions.
         By way of example, "CLEC Telecom Equipment" includes remote switch
         modules ("RSMs") and monitoring equipment installed in

                                      216
<PAGE>

          the Premises to send data to CLEC's work center for analysis.

By way of further example and of limitation, equipment used to provide
"information services" or "enhanced services" (as each is defined by applicable
federal statutes and regulations) is not permitted to be placed by CLEC in the
Premises or in the Eligible Structure, and thus are not included within "CLEC
Telecom Equipment."

2.2      Eligible Structure

         The structure in which the Premises is located, and is:

(a)      a NEVADA tandem office, central office, or serving wire center; or

(b)      a building or similar structure owned or leased by NEVADA that houses

         its network facilities; or

(c)      a structure that houses NEVADA facilities on public rights-of-way,

         including, where space exists and it is not impractical for technical
         reasons and not prohibited or restricted by legal obligation,
         controlled environment vaults ("CEVs'~, huts, and cabinets

               (i)  that serve as remote terminal sites and house NEVADA
                    interoffice network facilities such a loop concentrators or
                    multiplexers; and

                  (ii)     house interoffice network facilities.

2.3      Physical Collocation

         Physical Collocation is as defined in 47 C.F.R. Section 51.5.

2.4      Physical Collocation Arrangement

     Refers to a single, specific provision of Physical Collocation in a
particular

         Premises.

2.5      Power
         Refers to any electrical power source for use in or used within the
         Premises or Eligible Structure.

2.6      Premises
         The space designated for CLEC's Physical Collocation arrangement.
2.7      Virtual Collocation
         Virtual Collocation is as defined in 47 C.F.R. Section 51.5.

                                      217
<PAGE>

3.       APPLICATION

          3.1 CLEC shall complete and submit, along with any application charge,
          the then

          standard NEVADA application for Physical Collocation. Such application
          and associated instructions can be found in NEVADA's "Collocation
          Services Handbook" (as defined in Section 12. 1 (b)).

3.2      If a request by CLEC for Physical Collocation or to place a specific
         piece of telecommunications equipment in an Eligible Structure is
         denied on the basis of that equipment, NEVADA shall prove to the
         Commission that such equipment is not "necessary" (as defined by the
         FCC) for interconnection to NEVADA or access to its unbundled network
         elements, or that Physical Collocation of such equipment is not
         practical for technical reasons or is not allowed due to legal
         obligations or restrictions.

4.       SPACE AVAILABILITY

         4.1      NEVADA is not required to provide Physical Collocation at a
                  particular Eligible Structure if it demonstrates to the
                  Commission that Physical Collocation is not practical for
                  technical reasons or because of space limitations. In such
                  cases, NEVADA will provide Virtual Collocation, except at
                  points where NEVADA proves to the Commission that Virtual
                  Collocation is not technically feasible. If Virtual
                  Collocation is not technically feasible, NEVADA will provide
                  other methods of interconnection and access to unbundled
                  network elements to the extent technically feasible.

4.2      At the request of CLEC or direction of the Commission, NEVADA will
         submit to the Commission detailed floor plans or diagrams of any
         Eligible Structure where NEVADA claims that Physical Collocation is not
         practical because of space limitations, where such plans or diagrams
         exist. Where such plans or diagrams do not exist or when otherwise
         agreed, NEVADA and CLEC will either agree to an alternate method of
         addressing a NEVADA claim of space unavailability, or NEVADA will
         comply with the Commission's direction.

          4.3 NEVADA is not required to lease or construct additional space to
          provide for Physical Collocation when existing space has been
          exhausted. Moreover, NEVADA is not required to, nor shall this
          Appendix create any obligation or expectation, to relinquish used or
          forecasted space or facilities subject to the provisions hereof, or to
          undertake the construction of new quarters or to construct additions
          to existing quarters in order to satisfy any request for additional
          space or the placement of equipment or facilities, whether through an
          initial request for Physical Collocation or a subsequent request for
          more space in an Eligible Structure.

                                      218
<PAGE>

4.4      To the extent possible, NEVADA will make contiguous space available to
         CLEC if CLEC seeks to expand an existing Physical Collocation
         arrangement and such request meets NEVADA's non-discriminatory
         practices regarding efficient space utilization.

4.5      When planning renovations of existing Eligible Structures or
         constructing or leasing new Eligible Structures, NEVADA will take into
         account known projected demand for Collocation.

4.6      NEVADA may retain a limited amount of floor space for NEVADA's own
         specific future uses for a time period on terms no more favorable to
         NEVADA than those that apply to other telecommunications carriers,
         including CLEC, seeking to reserve Collocation space for their own
         future use. Except for space needed for switching equipment
         "turnaround" (e.g., the installation of new switching equipment to
         replace then-existing switching equipment), if any, NEVADA will
         relinquish any space held for future use before denying a request for
         Virtual Collocation on grounds of space limitations, unless NEVADA
         proves to the Commission that Virtual Collocation at that point is not
         technically feasible, including that space does not exist. In any such
         event, NEVADA and CLEC will attempt to reach a mutually agreeable
         alternative method of interconnection.
4.7      NEVADA may impose reasonable restrictions on its provision of
         additional unused space available for Collocation (so-called
         "warehousing") as described in paragraph 586 of the First
         Interconnection Order; provided, however, that NEVADA shall not set a
         maximum space limitation on CLEC unless NEVADA proves to the Commission
         that space constraints make such restrictions necessary.

5.       PREMISES AND PREPARATION

               5.1  NEVADA will construct the Premises in compliance with the
                    Parties mutually

          agreed-upon design for cable holes, ground bars, doors, and
          convenience outlets.

         After CLEC has made the initial preparation payment required hereunder
         (with the application charge, if any, not considered a preparation
         payment, initial or otherwise), NEVADA agrees to pursue diligently the
         preparation of the Premises for use by CLEC.

5.2      NEVADA shall provide the following to CLEC no later than the "First
         Customer Meeting," which is described in the Collocation Services
         Handbook.

(a)      non-architectural drawings depicting the location and dimensions of the
         Premises and any physical obstructions;
(b)      Telephone Equipment drawings depicting the path with dimensions for
         CLEC outside plant fiber ingress/egress into the Eligible Structure and

                                      219
<PAGE>

          Premises, if CLEC fiber is to be brought to the Physical Collocation
          arrangement;

          (e) NEVADA or industry technical publication guidelines that impact
          the

                  design of CLEC Telecom Equipment;

          (d) work restriction guidelines; (e) escalation process for NEVADA
          representatives (names, telephone

          numbers, escalation order) for any dispute or problem that might arise
          pursuant to CLEC's Physical Collocation;

          M- NEVADA contacts (name and telephone number) for the following
          areas,

          with CLEC to provide a list with counterparts for each such area:

                  (i)      Engineering

                  (ii)     Physical & Logical Security

                  (iii)    Provisioning

                  (iv)     Billing

                  (v)      Operations

                  (vi)     Site and/or Building Managers

5.3      NEVADA shall provide positive confirmation to CLEC when construction of
         CLEC Premises is underway. No later than the second meeting of CLEC and
         NEVADA representatives scheduled to address a Physical Collocation
         application ("Second Customer Meeting'% NEVADA shall notify CLEC of the
         scheduled completion and turnover dates, and shall provide CLEC the
         following: (a) drawings depicting the path, with dimensions, for CLEC's
         fiber
                  ingress/egress into the Premise; and

               (b)  power cabling connectivity information, including drawings,
                    identifying the sizes and number of power feeders.

5.4      CLEC and NEVADA will complete an acceptance walk-through of the
         Premises prior to turning the Premises over to CLEC. Exceptions that
         are noted during this acceptance walk-through shall be corrected by
         NEVADA as soon as commercially reasonable after those exceptions are
         provided in writing, which exceptions shall be provided no more than 5.
         days after the walk through. The correction of these

                                      220
<PAGE>

          exceptions from CLEC's Physical Collocation request shall be at
          NEVADA's expense.

5.5      NEVADA shall ensure that the Premises and the Eligible Structure comply
         with all applicable fire and safety codes. The preparation shall be
         arranged by NEVADA in compliance with all applicable codes, ordinances,
         resolutions, regulations and laws.

5.6      Movement of Premises

 5.6.1   In the event that NEVADA determines it necessary for the Premises to be
         moved within the Eligible Structure or to another NEVADA structure
         where Physical Collocation is offered, CLEC is required to do so. In
         such an event, CLEC shall be responsible for the preparation of the new
         premises at the new location if such relocation arises from
         circumstances beyond the reasonable control of NEVADA, including
         condemnation or government order or regulation that makes the continued
         occupancy of the Premises or Eligible Structure uneconomical in
         NEVADA's sole judgment. Otherwise NEVADA shall be responsible for any
         such preparation.

 5.6.2   In the event that CLEC requests that the Premises be moved within the
         Eligible Structure or to another NEVADA structure where Physical
         Collocation is offered, NEVADA shall permit CLEC to relocate, subject
         to the availability of space and associated requirements. CLEC shall be
         responsible for all applicable charges associated with the move,
         including the reinstallation of the CLEC Telecom Equipment and the
         preparation of the new structure to which the Physical Collocation
         arrangement is to be moved.

 5.6.3   In either such event, the new premises shall be deemed the "Premises"
         hereunder and the new structure the "Eligible Structure."

5.7      NEVADA agrees to negotiate CLEC requests for diversity of fiber or
         power cabling on an Individual Case Basis ("ICB") basis.

5.8      Bathroom access will be provided where available in common areas.

5.9      NEVADA will contract for and perform the construction and preparation
         activities underlying the "Preparation Charge," including the "Common
         Charge," the "Premises Charge," and the "Subcontractor Charges," and
         any "Custom Work" charges, using same or consistent practices that are
         used by NEVADA for

                                      221
<PAGE>

          other construction and preparation work performed in the Eligible
          Structure.

                  (Each of capitalized phrases in the preceding set apart by
quotation marks are defined in Section 7.)

                  5.9.1    Notwithstanding the above, NEVADA will permit CLEC to
                           subcontract the construction of Physical Collocation
                           arrangements with contractors approved by NEVADA,
                           provided that NEVADA will not unreasonably withhold
                           approval of contractors. Approval by NEVADA will be
                           based on the same criteria NEVADA uses in approving
                           contractors for its own purposes.

6.       TERM
         6.1      Unless otherwise terminated by CLEC providing sixty (60) days'
                  written notice, any Physical Collocation arrangement hereunder
                  shall terminate when and in the same manner that this
                  Agreement terminates.
         6.2      Unless there are unusual circumstances, a Physical Collocation
                  arrangement shall be established within the time frames
                  provided in NEVADA's Tariff FCC No. 1, Section 18, as may be
                  amended from time to time, which time frame is currently one
                  hundred eighty (180) days in most cases. NEVADA will promptly
                  notify CLEC upon completion of the preparation of the Premises
                  and will permit CLEC's use thereof as soon as such
                  arrangements are available.

          6.3 CLEC must place CLEC Telecom Equipment in the Premises and
          interconnect to

                  NEVADA's network or to its unbundled network elements within
                  sixty (60) days after receipt of such notice. If CLEC fails to
                  do so, NEVADA may, upon notice, terminate that Physical
                  Collocation arrangement, and CLEC shall be liable in an amount
                  equal to the unpaid balance of the charges due under and,
                  further, shall continue to be bound by the provisions of this
                  Appendix, the terms or context of which indicate continued
                  viability or applicability beyond termination. For purposes of
                  this Section, CLEC Telecom Equipment is considered to be
                  interconnected when physically connected to NEVADA's network
                  or a NEVADA unbundled network element for the purpose of CLEC
                  providing a telecommunications service.

7.       PREMISES CHARGES

          7.1 The charges for a Physical Collocation arrangement in an Eligible
          Structure where

          interstate expanded interconnection is required to be provided
          pursuant to 47

          C.F.R. [two section symbols] 64.1401(a), 64.1401(b)shall be as set
          forth in Nevada's FCC Tariff No. 1, Section 18. To the extent that any
          of those charges are subject to appeal, the result of any such appeal
          shall be retroactively applied to any Physical Collocation arrangement
          ordered or provided under any such charge.

                                      222
<PAGE>

7.2      In the event that any CLEC Telecom Equipment that is to be placed in
         the Premises was not contemplated by that interstate tariff (which was
         based upon the requirements of 47 C.F.R. Section 64.1401), CLEC may be
         subject to additional
charges
         under an ICB if NEVADA's costs of providing the necessary Premises
         requirements (eg., space, power, environmental, grounding) for any such
         CLEC Telecom Equipment is not recovered by those tariffed rates. Any
         ICB quote shall be included as part of the quote provided to the CLEC
         in response to its Physical Collocation application. To the extent that
         any such quote separately states a quote for subcontractor charges,
         such charges shall be subject to the true-up process contemplated in
         Section 7.3(f).

7.3      The charges for a Physical Collocation arrangement that is provided in
         an Eligible Structure not included in Section 7.1 ("Other Eligible
         Structure") shall be determined on Individual Case Basis ("ICB") in
         accordance herewith.

          (a) An ICB quote will be prepared and provided to CLEC after it
          submits an

          application for a Physical Collocation arrangement in an Other
          Eligible

                  Structure.

(b)      The quote shall consist of the following components:

(i)      monthly recurring charges; and
(ii)     the estimate of the one-time charge associated with preparing the

         Premises for Physical Collocation (the "Preparation Charge"),

         which will consist of two components: (A) the charge to CLEC associated
         with modifying the Eligible Structure to provide Physical Collocation
         ("Common Charge'% and (B) the charge associated with preparing the
         Premises ("Premises Charge"). Of the Preparation Charge, a separate
         amount will be estimated for total subcontractor charges
         ("Subcontractor Charges"); and

 (iii) any custom work charge needed to create or vacate an entrance facility
for CLEC ("Custom Work").

     (c) CLEC will have sixty-five (65) business days in which to either accept
or

         reject NEVADA's quote.

          (d) Prior to any NEVADA obligation to start any preparation of the
          Premises,

         CLEC shall pay NEVADA fifty percent (50%) of the quoted Premises

         Charge, fifty percent (50%) of the quoted Common Charges, and eighty
         five percent (85%) of any quoted Custom Work charge. Such amounts shall
         be due no later than ten (10) business days after the CLEC accepts

                                      223
<PAGE>

         the ICB quote. If such amounts are not received, the acceptance is
         deemed void and shall be treated as having not been given.

         The remainder of the quoted Premises Charge, the quoted Common Charge,
         and any quoted Custom Work charge are due from CLEC before NEVADA has
         any obligation to permit CLEC to occupy the Premises.

         NEVADA will not permit CLEC to have access to the Premises for any
         purpose other than inspection until NEVADA is in receipt of complete
         payment of all quoted non-recurring charges due hereunder.

         Within one hundred twenty (120) days of the completion date of the
         Premises, NEVADA will perform a true-up of all Subcontractor Charges
         using the actual amounts billed by subcontractors. Any amounts charged
         above the Subcontractor Charges will be billed to CLEC or,
         alternatively, any amount below such Charges will be remitted to CLEC.

         (i)      Subject to an appropriate non-disclosure agreement, NEVADA

                  will permit CLEC to inspect supporting documents for the
                  Preparation Charge, including the Common Charge if CLEC is the
                  "initial physical collocator" (as such phrase used herein),
                  the Premises Charge, and any Custom Work charge. Any dispute
                  regarding such NEVADA charges will be subject to the dispute
                  resolution provisions outlined in the General Terms and
                  Conditions of this Agreement.

(g)      The first carrier to which NEVADA provides Physical Collocation in a

         particular Other Eligible Structure shall be responsible for all costs
         incurred by NEVADA associated with the preparation of that Eligible
         Structure to provide Physical Collocation in the space where Physical
         Collocation is to be located ("Initial Common Charge"). Thereafter the
         Initial Common Charge will be prorated and the prorated share refunded
         to the previous physical collocator(s) if and as additional carriers
         use Physical Collocation in that same Other Eligible Structure within
         twelve (12) months of the first billing date of the initial monthly
         recurring charge for the first physical collocator in that Other
         Eligible Structure, using the following schedule:

<PAGE>

                           To the extent that a physical collocator uses a space
                           other than such initial space, NEVADA shall refund to
                           CLEC the portion of the Initial Common Charge
                           applicable to such collocator based on the relative
                           use of such initial space in a manner consistent with
                           the above methodology and other terms of this
                           Appendix. CLEC will be charged in accordance with the
                           above (e.g., if CLEC is first collocator, if CLEC is
                           second collocator).

          (h) No interest will be paid on any refund. Refunds shall be based on
          the

                           Initial Common Charge actually paid by the first
                           physical collocator and, similarly, the Initial
                           Common Charge paid by subsequent collocators.

          (i) Notwithstanding any other provision hereof, NEVADA shall have no

                           obligation to refund any amount that would result in
                           NEVADA being unable to retain the full amount of the
                           Initial Common Charge or to refund any amount based
                           upon charges not actually collected.

          The monthly recurring charge(s) in an Other Eligible Structure may be

                            increased upon thirty (30) days' notice by NEVADA.

         7.4      In the event that CLEC materially breaches this Appendix by
                  purporting to terminate the Physical Collocation arrangement
                  after NEVADA has begun preparation of the Premises but before
                  NEVADA has been paid the entire nonrecurring amounts due under
                  this Appendix, then in addition to any other remedies that
                  NEVADA might have, CLEC shall be liable in the amount equal to
                  the non-recoverable costs less estimated net salvage.
                  Non-recoverable costs include, as applicable, the
                  non-recoverable cost of equipment and material ordered,
                  provided or used; trued-up Subcontractor Charges, the
                  non-recoverable cost of installation and removal, including
                  the costs of equipment and material ordered, provided or used;
                  labor, transportation and any other associated costs.

         7.5      The monthly recurring charge(s) shall begin to apply no later
                  than the date that NEVADA sends written notice to CLEC that
                  NEVADA has completed the preparation of the Premises,
                  including to the extent possible in light of the failure by
                  CLEC to complete its work (eg., late in providing a fiber
                  optic cable to pull into the Eligible Structure). The fact
                  that NEVADA may have additional work to perform after CLEC
                  does complete its work shall not bar the start of such
                  charges.

8.       BILLING

         8.1      Payment of any amount charged hereunder shall be due thirty
                  (30) days from the billing date. NEVADA may change its billing
                  date practices upon thirty (30) days notice to CLEC.

                                      225
<PAGE>

         8.2      In the event that any charge is not paid when due, the unpaid
                  amounts shall bear interest in accordance with the terms and
                  conditions set forth in NEVADA's intrastate tariff late
                  payment provision(s) applicable to access services, or the
                  highest rate permitted by law, whichever is lower, from the
                  due date until paid.

9.       INTERCONNECTION CHARGES

         9.1      Charges for interconnection shall be as set forth in this
Agreement and any
                  applicable NEVADA tariffs.
         9.2      NEVADA shall provide an Expanded Interconnection Service Cross
                  Connect ("EISCT") or applicable point-of-access cross connects
                  for intraoffice cross connects (described in Appendix UNE) as
                  requested by CLEC to meet CLEC's need for placement of CLEC
                  Telecom Equipment, interconnection, or provision of
                  telecommunications service. CLEC requests for cross connects
                  at transmission rates not specified in Appendix UNE are
                  subject to the bonafide request process described therein.
         9.3      CLEC shall have the right, at the point of termination for the
                  cross connect, to assign the tie pair facilities and the
                  channels on CLEC Telecom Equipment located within the
                  premises, under CLEC's control, that are used for
                  telecommunications service in the Physical Collocation
                  arrangement.

10.      SERVICE COORDINATION

         Transferring CLEC interconnection from NEVADA's current access service
         transport or entrance facilities to cross connects will be accomplished
         within a mutually agreed-upon time frame; however, to ensure a smooth
         transition from such access services to point of access cross connects,
         CLEC must provide forecasts of its future needs for cross connect
         capacity on a Premises-by-Premises basis at least ninety (90) days in
         advance of CLEC's desired transition date.

11.      USE OF PREMISES

         11.1     The Premises are to be used by CLEC for purposes of placing
                  CLEC Telecom Equipment for the purposes of interconnecting
                  with NEVADA under 47 U.S.C. Section 251(c)(2), or obtaining
                  access to its unbundled network elements under 47 U.S.C.
                  Section 251(c)(3). Equipment used to provide "information
                  services" or "enhanced services" (as each is defined by

 11.2    A list of all of CLEC Telecom Equipment that will be placed within the
         Premises shall be set forth on the CLEC's Physical Collocation
         application, which includes associated power requirements, floor
         loading, and heat release of each piece of CLEC Telecom Equipment. CLEC
         wan-ants and represents that the Physical Collocation application
         contains a complete and accurate list of such. CLEC Telecom Equipment,
         and acknowledges that any incompleteness or inaccuracy would be a
         breach of this Appendix. CLEC shall not place or leave any other
         equipment or facilities within the Premises without the express written
         consent of NEVADA.

 11.3    In the event that subsequent to the submission of the Physical
         Collocation application and its list of CLEC Telecom Equipment with the
         required technical information, CLEC desires to place in the Premises
         any telecommuni cations equipment or such ancillary telecommunications
         facilities not so set forth in the Physical Collocation application,
         CLEC shall furnish to NEVADA a new Physical Collocation application to
         cover such equipment or facilities. Thereafter, consistent with its
         obligations under the Act and applicable FCC and Commission rules,
         orders, and awards, NEVADA may provide such written consent- or may
         condition any such consent on additional charges arising from the-
         request; including any engineering design charges and any additional
         requirements such aspower and environmental requirements for such
         requested telecommunications equipment and/or facilities. Upon the
         execution by both NEVADA and CLEC of a final list and description and
         receipt by NEVADA of payment of any applicable non-recurring charges,
         the Physical Collocation arrangement shall be deemedto have been
         amended and such requested telecommunications equipment and/or
         facilities shall be included within "CLEC Telecom Equipment."

 11.4    CLEC may use the Premises for placement of CLEC Telecom Equipment only.
         CLEC's employees, agents and contractors shall be permitted access- to-
         the Premises at all reasonable times, provided that CLEC's employees,
         agents: and contractors comply with NEVADA's policies and practices
         pertaining. to-- fire and security. CLEC agrees to comply promptly with
         all laws, ordinances and regulations affecting the use of the Premises.

 11.5    Other than the security restrictions described herein, NEVADA shall
         place no restriction on access to CLEC's Premises by CLECs employees
         and desi gnated Such space shall be available to CLEC designated agents
         twenty-four (24) hours per day each day of the week. NEVADA will not
         impose unreasonable security restrictions for the Eligible Structure,
         including the Premises.

 11.6    Upon the expiration of a Physical Collocation arrangement, CLEC shall
         surrender the Premises to NEVADA, in the same condition as when first
         occupied by CLEC, ordinary wear and tear excepted.

         impair the privacy of any communications carried in, from, or through
         the Eligible Structure; or create hazards or cause physical harm to any
         person, entity, or the public. Any of the foregoing events would be a
         material breach of this Appendix.

 11.9    NEVADA will permit CLEC to interconnect the CLEC Telecom Equipment with
         other telecommunications carriers Collocating in the Eligible
         Structure; provided, however, that any CLEC Telecom Equipment is also
         used for interconnection with NEVADA or for access to its unbundled
         network elements. NEVADA will provide such connection between CLEC and
         such other Collocating telecommunication carriers via cage-to-cage
         cross connections and any necessary Digital Cross Connect ("DCSS") or
         other telecommunications equipment at CLEC's expense, unless NEVADA
         permits one or more of the Collocating carriers to provide this
         connection for themselves. NEVADA need not permit CLEC or other
         collocating telecommunications carriers to place its own connecting
         transmission facilities within the Eligible Structure outside of the
         Premises. Rates for cage-to-cage connections are as described in
         Appendix PRICING.

 11.10   Subject to the limitations and restrictions of this Appendix, CLEC may

         the Premises shall not become a part of the Premises, even if nailed,
         screwed or otherwise fastened to the Premises, but shall retain their
         status as personal property and may be removed by CLEC at any time. Any
         damage caused to the Premises by the removal of such property shall be
         repaired at CLEC's expense.

     11. 11 In no case shall CLEC or any person or entity purporting to be
acting through or on behalf of CLEC make any- rearrangement, modification,
improvement, addition, repair, or other alteration to the Premises or the
Eligible Structure without the advance written permission and direction of
NEVADA. NEVADA

     14.12 CLEC is responsible for coordinating with NEVADA to ensure that
services are installed in accordance with a service request.

 14-13   CLEC is responsible for testing, to identify and clear a trouble when
         the trouble has been isolated to inside the Premise, or to any piece of
         CLEC Telecom Equipment, or any other CLEC-provided facility or piece of
         equipment. If NEVADA testing is also required, it will be provided at
         charges specified in NEVADA's tariff PSCN C, Section 13.

15.      ASSIGNMENT

CLEC shall not assign or otherwise transfer any Physical Collocation arrangement
provided under this Appendix, neither in whole nor in part, or permit the use of
any part of the Premises by any other person or entity, without the prior
written consent of NEVADA. Any purported assignment or transfer made without
such consent shall be voidable at the option of NEVADA. CLEC shall not permit
any third party to jointly occupy the Premises.

16,      CASUALTY LOSS

 16.1 If the Eligible Structure or the Premises are damaged by fire or other
casualty, and:

(a)      the Premises are not rendered untenantable in whole or in part, NEVADA

         shall repair the same at its expense (as herein limited) and the
         recurring
         charges shall not be abated, or

(b)       the Premises are rendered untenantable in whole or in part and such

         damage or destruction can be repaired within ninety (90) days, NEVADA
         has the option to repair the Premises at its expense (as herein
         limited) and the recurring charges, shall be proportionately abated to
         the extent and while CLEC was deprived of the use. If the Premises
         cannot be repaired within ninety (90) days, or NEVADA opts not to
         rebuild, then the Physical

                                      233
<PAGE>

                  Collocation arrangement provided in the Premises shall (upon
                  notice to CLEC within thirty (30) days following such
                  occurrence) terminate as of the date of such damage.

 16.2    Any obligation on the part of NEVADA to repair the Premises shall be
         limited to repairing, restoring and rebuilding the Premises as
         originally prepared for CLEC and shall not include any obligation to
         repair, restore, rebuild or replace any alterations or improvements
         made by CLEC or by NEVADA on request of CLEC; any CLEC Telecom
         Equipment; or other facilities or equipment located in the Premises by
         CLEC or by NEVADA on request of CLEC.

 16.3    In the event that the Eligible Structure shall be so damaged by fire or
         other casualty that closing, demolition or substantial alteration or
         reconstruction thereof shall, in NEVADA's opinion, be advisable, then,
         notwithstanding that the Premises may be unaffected thereby, NEVADA, at
         its option, may terminate any Physical Collocation arrangement in that
         Eligible Structure by giving CLEC ten (10) days prior written notice
         within thirty (30) days following the date of such

         occurrence, if at all possible.

17.

 17.1    Unless otherwise set forth herein, if CLEC shall default in performance
         of any term or condition herein, and the default shall continue for
         thirty (30) days after receipt of written notice, or if CLEC is
         declared bankrupt or insolvent or makes an assignment for the benefit
         of creditors, NEVADA may, immediately or at any time thereafter,
         without notice or demand, enter and repossess the Premises, expel CLEC
         and any claiming under CLEC, remove any CLEC Telecom Equipment and any
         other items in the Premises, forcibly if necessary, and thereupon such
         Physical Collocation arrangement shall terminate, without prejudice to
         any other remedies NEVADA might have. NEVADA may exercise this
         authority on a Premises-byPremises basis.

 17.2    NEVADA may also refuse additional applications for collocation and/or
         refuse to complete any pending orders for additional space or
         collocation by CLEC at any time thereafter.

18.      LIMITATION OF LIABILITY

 18.1    With respect to any claim or suit -for damages arising in connection
         with the mistakes, omissions, interruptions, delays or errors, or
         defects in transmission occurring in the course of furnishing service
         hereunder, the liability of NEVADA, if any, shall not exceed an amount
         equivalent to the proportionate monthly charge to CLEC for the period
         during which such mistake, omission, interruption, delay, error, or

 18.6    NEVADA shall not be liable for any act or omission of any other carrier
         or customer providing a portion of a service, nor shall NEVADA for its
         own act or omission hold liable any other carrier or customer providing
         a portion of a service.

 18.7    When CLEC is provided Physical Collocation under this Appendix, NEVADA
         shall be indemnified, defended and held harmless by CLEC against any
         claim, loss or damage arising from CLEC's use of NEVADA's Premises
         provided under this Appendix, involving:

(a)      claims for libel, slander, invasion of privacy, or infringement of
         copyright

         arising from the customer's own communications;

          (b) claims for patent infringement arising from the customer's acts
          combi i g

          or using the service furnished by NEVADA in connection with facilities
          or equipment furnished by the customer; or

                                      235

     (c) all other claims arising in connection with any act or omission of CLEC
in

               the  course of using Physical Collocation provided pursuant to
                    this Appendix.

          18.8    CLEC acknowledges and understands that NEVADA may provide
                  space in or access to the Eligible Structure to other persons
                  or entities ("Others"), which may include competitors of
                  CLECs; that such space or access may be close to the Premises,
                  possibly including space adjacent to the Premises and/or with
                  access to the outside of the Premises; and that any cage
                  placed around the Premises is a permeable boundary that will
                  not prevent the Others from observing or even damaging CLECs
                  equipment and facilities. In addition to any other applicable
                  limitation, NEVADA shall-have absolutely no liability with
                  respect to any action or omission by any Other, regardless of
                  the degree of culpability of any such Other or NEVADA, and
                  regardless of whether any claimed NEVADA liability arises in
                  tort or in contract. CLEC shall save and hold NEVADA harmless
                  from any and all costs, expenses, and claims associated with
                  any such acts or omission by any Other acting for, through, or
                  as a result of CLEC.

         officers, directors, employees, and other agents) from any and all
         claims, liabilities, losses, damages, fines, penalties, costs,
         attorney's fees or other expenses of any kind, arising in connection
         with CLEC's use of the Premises, conduct of its business or any
         activity, in or about the Premises, performance of any terms of this
         Appendix, or any act or omission of CLEC (including its officers,
         directors, employees, agents, contractors, servants, invitees, or

         sufficiently in advance, such service shall be available at Premises on
         the day that the space is turned over to CLEC by NEVADA.

 20.3    NEVADA will provide negative DC and AC power, back-up power, lighting,

         equipment or any other personal property belonging to CLEC or located
         on or in the space at the instance of CLEC by reason of fire or water

         regardless of cause or origin, including negligence of NEVADA, its
         agents, directors, officers, employees, independent contractors, and
         other representatives. Property insurance on CLECs fixtures and other
         personal property shall contain a waiver of subrogation against NEVADA,
         and any rights of CLEC against NEVADA for damage to CLEC's fixtures or

<PAGE>

minimum limits as shall then be customary in respect of comparable situations
within the existing NEVADA structure.

               25.4 All policies purchased by CLEC shall be deemed to be primary

         remain in force as long as any of CLEC's Telecom Equipment or other
         CLEC facilities or equipment remain within the Premises or the Eligible
         Structure. If CLEC fails to maintain the coverage, NEVADA may pay the
         premiums thereon and, if so, shall be reimbursed by CLEC.

 25.6    CLEC shall submit certificates of insurance and policy binders
         reflecting the coverages specified above prior to, and as a condition

         to Section 5.9.1. CLEC shall arrange for NEVADA to receive thirty (30)
         days advance written notice from CLEC's insurance company(ies) of
         cancellation, non-renewal or substantial alteration of its terms.

         Insurance Company, if any, unless a recommendation is also applicable
         to NEVADA and NEVADA does not so conform in the Eligible Structure
         where the Premises is located.

               25.8 Failure to comply with the provisions of this "Insurance"
                    Section will be deemed a material violation of this
                    Appendix.

         available twenty-four (24) hours a day, seven (7) days a week.

26.2     Except as may otherwise be provided:

26.8     NEVADA shall allow CLEC to inspect or observe spaces which house or
         contain CLEC equipment or equipment enclosures at any time within
         normal business hours and shall furnish CLEC with all keys, entry

         actual security breach.

 26.12   NEVADA shall be responsible for the security of the Eligible Structure.
         If a security issue arises or if CLEC believes that NEVADA's security
         measures are unreasonably lax, CLEC shall notify NEVADA and the Parties
         shall work together to address the problem. NEVADA shall, at a minimum,
         do the following:

 26.12.1    Where a cage is used, NEVADA shall design collocation cages to
            prevent unauthorized access; provided, however, that CLEC realizes
            and assents to the fact that the cage will be made of wire mesh.

 26.12.2    NEVADA shall establish procedures for controlling access to the
            collocation areas by employees, security guards and others. Those
            procedures shall limit access to the collocation areas to NEVADA's
            employees, agents or invitees having a business need, such as a
            periodic review of the premises, to be in these areas. NEVADA shall
            require all persons entering the collocation areas to wear
            identification badges.

 26.12.3    NEVADA shall provide card key access to all collocation equipment
            areas where a secured pathway to the collocation space is made
            available to collocators, along with a positive key control system
            for each collocator's caged Premises.

         26.12.4     In emergency situations common courtesy will be extended
                     between CLEC and NEVADA's employees, including the
                     provision of first aid and first aid supplies.

         NEVADA location for compliance with security procedures.

 26.14   CLEC shall limit access to CLEC employees directly to and from
the Premises and will not enter unauthorized areas under
         any circumstances.

27.      PURPOSE AND SCOPE OF THIS APPENDIX

         Through this Appendix, CLEC is placing the CLEC Telecom Equipment on
         NEVADA property for the purposes of interconnecting with NEVADA and
         obtaining access to its unbundled network elements. This Appendix does
         not constitute, and shall not be

                                      241
<PAGE>

asserted to constitute, an admission or waiver or precedent with the Commission,
the FCC, any other regulatory body, any State or Federal Court, or in any other
form that NEVADA has agreed or acquiesced that any particular piece of CLEC
Telecom Equipment -is "equipment necessary for interconnection or access to
unbundled network elements" under 47 U.S.C. Section 251(c)(6), or that such
piece must be provided in a Virtual Collocation arrangement.

         CLEC in requesting or maintaining a Physical Collocation arrangement.
         NEVADA shall not provide such information to any third parties and
         shall limit access to the information to NEVADA or affiliated employees
         having a need to know.

 28.2    If CLEC constitutes more than one person, partnership, corporation, or
         other legal entities, the obligation of all such entities under this
         Appendix is joint and several.

 28.3    NEVADA may refuse requests for additional space in the Eligible
         Structure or in any other NEVADA premises if CLEC is in material breach

         any and each such event, CLEC hereby releases and shall hold NEVADA
         harmless from any duty to negotiate with CLEC or any of its affiliates
         for any additional space or Collocation arrangement.

 28.4    If any of the provisions hereof are otherwise deemed invalid, such
         invalidity shall not invalidate the entire Appendix, but rather the
         entire Appendix shall be construed as if not containing the particular
         invalid provision(s), and the rights and obligations of NEVADA and CLEC
         shall be construed accordingly.

 28.5    The headings contained herein are inserted for convenience only and

         authority, or option reserved by this Appendix (including the right to
         demand exact compliance with every term, condition and covenant herein,
         or to declare any breach hereof to be a default and to terminate this
         Appendix prior to the expiration of its term), by virtue of any custom
         or practice of the Parties at variance with the terms hereof or any
         failure, refusal or neglect to exercise any right under this Appendix
         or to insist upon exact compliance by the other with its obligations
         hereunder, including any rule or procedure, or any waiver, forbearance,
         delay, failure or omission by

                                      242
<PAGE>

NEVADA to exercise any right, power or option, whether of the same, similar or
different nature, with respect to one or more other CLECs.

 28.8    The rights of a Party hereunder are cumulative and no exercise or
         enforcement by such Party of any right or remedy hereunder shall
         preclude the exercise or enforcement of any other right or remedy
         hereunder or to which such Party is entitled to enforce.

 28.9    This Appendix is binding upon the Parties hereto, their respective
         executors, administrators, heirs, assigns and successors in interest.

 28.10   All obligations by either Party which expressly or by their nature
         survive the expiration or termination of this Appendix shall continue
         in full force and effect subsequent to and notwithstanding its
         expiration or termination and until they are satisfied in full or by
         their nature.

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

     Overall Assumptions:
     --------------------
     a)  Zone for loops are defined as 1, 2, and 3.
          Zone 1 for loops includes RENONV02, SPRKNV11, RENOVN13, CRCYN01,
          RENONV12, RENONV14, and RENONV15.
          Zone 2 for loops includes INVGNV11, STEDNV11, SNVYNV11, SPRKNV12,
             DYTNNV11, WASONV11, FRNLNV11, VERDNV11, SVSPNV11, VRCYNV12,
             CHBTNV11, LCWDNV11, and CRPLNV11.
          Zone 3 for loops includes all other offices not defined in zone 1 or
          2.
     b)  Zones for local switching capability, Port features, Vertical features
         and Optional Centrex features are defined as Zone 1 and Zone 2.
          Zone 1 includes offices identified in Zones 1 and 2 for loops above.
          Zone 2 includes offices identified in Zone 3 for loops above.
     c)  Zones for interoffice transmission are defined Zone 1 and Zone 2.
          Zone 1 includes offices identified in Zones 1 and 2 for loops above.
          Zone 2 includes a statewide average for all offices identified in
          Zones 1, 2 and 3 for loops above.
     d)  For non-recurring activities, changes are defined as a request for an
         addition, partial disconnect, rearrangement or modification of the
         existing end user arrangement.

     Notes:
     ------
     1) Recurring variable costs are per airline mile.
     2) BFR refers to Innerconnect Network Element Request and relates to
        feasibility of the project. ICB refers to Individual Case Basis Study
        and shows that each request varies in cost.
     3) The non-recurring charges shown here can apply to all initial non-
        recurring service order, disconnect and change activities.
     4) The recurring charge will be determined when Nevada/California begins
        measuring this element.
     5) Once Nevada Bell deploys the technology and successful testing is
        completed, then the costing for this element can be completed.
     6) CLEC must order a minimum of 2 Trunks.
     7) Vendor pre-conditioning costs by switch technology are to be addressed
        through the ICB process and are in addition to prices displayed for the
        rate element.
     8) Currently there is no TOPS Switch in Zone 2; therefore, there are no
        applicable rates.

2.       TERMS AND CONDITIONS OF SERVICE

2.1      Telecommunications Services will be resold to CLEC on terms and
         conditions that are reasonable and nondiscriminatory. For services
         included in this Appendix, all the use restrictions and limitations and
         the rules and regulations contained in NEVADA's corresponding tariffs
         apply to CLEC's End Users.
2.2      Except where otherwise explicitly provided in the corresponding tariffs
         established by the Commission, CLEC shall not permit the sharing of a
         service by multiple End Users or the aggregation of traffic from

2.3      The rights, obligations and duties set forth in this Appendix are
         subject to the Act, regulations thereunder, and relevant Commission
         decisions.

2.4      CLEC shall resell these telecommunications services only to the same
         class of customers to which NEVADA sells the services, e.g. residence
         service may not be resold to business customers. CLEC may only resell
         Lifeline Assistance, Link Up, and other like services to similarly

<PAGE>

such services. Further, to the extent CLEC resells services that require
certification on the part of the buyer, CLEC will ensure that the buyer has
received proper certification and complies with all rules and regulations as
established by the Commission.

2.5      NEVADA shall apply the wholesale discount to the retail price or

2.5.1    If NEVADA offers a new Telecommunications Service or a
         Telecommunications Service which has not been tariffed on a short-term

         promotional basis, it must establish the standard retail price or
        ordinary

         rate for those Telecommunications Services and make those

         Telecommunications Services available to CLEC at that price less the
         wholesale discount.

2.5.2    Nothing in this Agreement shall require NEVADA to provide to CLEC
         promotional service elements that are not Telecommunications Services
         such as CPE and Inside Wire Maintenance Plans.

2.6      CLEC shall not use a resold service to avoid the rates, terms and
         conditions of NEVADA's corresponding retail tariff.
2.7      CLEC shall not use resold local exchange telephone service to provide
         access or interconnection services to itself, interexchange carriers
         ("IXCs'), wireless carriers, competitive access providers ("CAPs") or
         other telecommunications providers. CLEC may permit its End Users to
         use resold local exchange telephone service to access IXCs, wireless
         carriers, CAPs, or other retail telecommunications providers.

2.8      An End User Common Line ("EUCL") charge and any other mandated charge
         will continue to apply for each local exchange line resold under this
         Appendix. All federal rules and regulations associated with EUCL
         charges, as found in Tariff FCC No. 1, also apply. Revenues from access
         charges, whether usage sensitive or flat rated, will be retained by
         NEVADA.

               2.9  To the extent allowable by law, CLEC shall be responsible
                    for Primary Interexchange Carrier ( "PIC") change. charges
                    associated with such local exchange line. CLEC shall pay for
                    PIC changes at the tariffed rate.

2.10     NEVADA shall provide the services covered by this Appendix subject to
         availability of existing facilities and on a nondiscriminatory basis
         with its other customers. CLEC shall resell the services provided

areas in which such resale services or any feature or capability thereof are
offered at retail by NEVADA as the incumbent local exchange carrier to its End
Users.

 2.11    When CLEC migrates an End User currently receiving service from
         NEVADA's network, without any changes to NEVADA's network, and such
         order requires manual processing by NEVADA personnel, CLEC will be
         charged an interim per order (i.e., per billable telephone number)
         conversion charge as outlined in Appendix PRICING. The rate for
         migration orders processed and completed electronically will be
         determined at a later date.

         2.11.1   When CLEC converts an End User and adds or changes are made to
                  the network, the respective migration charge will apply, as
                  well as any normal service order charges associated with said
                  changes. All nonrecurring service connection charges,
                  excluding the migration charge mentioned above, will be
                  charged at the appropriate wholesale discount for those
                  services listed in the Exhibits to this Appendix.

 2.12    For the purposes of ordering new service under this Appendix, each
         request for service shall be handled as a separate and initial request
         for service per billable telephone number. The additional line rate for
         Service Order Charges shall apply only to those requests for additional
         residential service at the End User's same location where a residential
         line is currently provided on NEVADA's network, regardless of the
         non-facilities based local service provider of record.

 2.12.1  For purposes of this section, service orders for CLECs shall be handled
         in the same fashion as NEVADA requires for its End Users.

 2.13    If CLEC is in violation of a provision of this Appendix, NEVADA will
         notify CLEC of the violation in writing. Such notice must refer to the
         specific provision being violated. At such time, CLEC will have thirty
         (30) days to correct the violation and notify NEVADA in writing that
         the violation has been corrected. NEVADA will then bill CLEC for the
         charges which should have been collected by NEVADA or the actual
         revenues collected by CLEC from its End Users for the stated violation,
         whichever is greater. Should CLEC dispute the violations, it must
         notify NEVADA in writing within fourteen (14) days of receipt of notice
         from NEVADA. Disputes will be resolved as outlined in the Dispute
         Resolution Section of the General Terms and Conditions of this
         Agreement.

               2.14 NEVADA is not required to make services available for resale
                    at wholesale rates to CLEC for its own use.

               2.15 The effective date of this Appendix shall be ten (10) days
                    after the date the Commission approves the Interconnection
                    Agreement.

            provided to NEVADA's subscribers. It is the Parties' expectation
            that separately bound NEVADA Bell Yellow Pages directories will be
            delivered in the same manner and at the same time to CLEC's
            subscribers as to NEVADA's subscribers.

 3.2.1.3    If CLEC's End User already has a current NEVADA directory, NEVADA

                             charges.

          3.2.1.5 Additional Listing Services (e.g., foreign listings) can be
          purchased by CLEC for its End Users on a per listing basis. CLEC shall
          pay NEVADA for all such listings provided to CLEC's End Users.

                  3.2.1.6    CLEC hereby releases NEVADA from any and all
                             liability for damages due to errors or omissions in
                             CLECs subscriber listing information as it appears
                             in the White Pages directory, including, but not
                             limited to, special, indirect, consequential,
                             punitive or incidental damages. To the extent CLEC
                             reimburses its End User subscriber any listing
                             charge due to errors or omissions caused directly
                             by NEVADA, NEVADA shall reimburse CLEC any
                             associated wholesale rate.

         NEVADA shall provide CLEC's End Users access to NEVADA's Directory
         Assistance Service. CLEC shall pay NEVADA amounts attributable to

         associated with the utilization of Directory Assistance Service are
         outlined in the Exhibits to this Appendix.

3.4      Operator Services

         3.4.1    NEVADA shall provide CLEC's End Users access to NEVADA's
                  Operator Services. CLEC shall pay NEVADA amounts attributable
                  to Operator Services used by CLEC's End Users. Discounts
                  associated with the utilization of Operator Services features

                  CLEC's End Users. CLEC shall pay NEVADA associated charges
                  when its End Users request such services as outlined in the
                  Exhibits of this Appendix.

3.5      Should CLEC choose to suspend their End User through Company Initiated
         Suspension Service, this suspension period shall not exceed fifteen
         (15) calendar days. CLEC shall be billed a suspend charge per CLEC's
         End User billing telephone number, as outlined in Appendix PRICING.
         When CLEC issues a disconnect on the same end user account within
         fifteen (15) days after the suspension service has been ordered or
         after the fifteen (15) day suspension

                                      261

                  period, CLEC shall be responsible for all appropriate charges
                  on the account back to the suspension date. Should CLEC

                  appropriate monthly service from the time of suspension.

4.       BRANDING

4.1      Except where otherwise required by law, CLEC shall not, without
         NEVADA's written authorization, offer the resale services covered by
         this Appendix using the trademarks, service marks, trade names, brand
         names, logos, insignia, symbols or decorative designs of NEVADA or its
         affiliates, nor shall CLEC state or imply that there is any joint
         business association or similar arrangement with NEVADA in the
         provision of Telecommunications Services to CLEC's own End Users. CLEC
         may brand services included in this Appendix with its own brand name,
         but NEVADA shall not be responsible for providing such branding.
4.2      Requirements

         Pursuant to Section 226 (b) of The Telecommunications Act of 1996, each
         provider of Operator Services is required to:

               (a)  provide its brand at the beginning of each telephone call
                    and before the consumer incurs any charge for the call; and

               (b)  disclose immediately to the consumer, upon request, a quote
                    of its rates or charges for the call.

4.3      Call Branding

         Currently NEVADA is unable to provide unique branding for CLEC. All
         calls will be unbranded. When NEVADA has the capability to uniquely
         brand CLEC calls, the Parties shall negotiate the specific price,
         terms, and conditions for this service.

4.4      Rate/Reference Information

         Currently NEVADA is unable to provide unique Rate/Reference
         Information. When NEVADA has the capability to provide unique
         Rate/Reference Information for CLECs, the Parties shall negotiate the
         specific price, terms, and conditions for this service. In the interim,
         CLEC specific rate quotes will only be provided when CLEC's OS rates
         exactly mirror NEVADA's rates. To the extent CLEC provides NEVADA its
         customer. service center number, NEVADA will provide such referral
         number to CLEC's End User customer for all other rate quotes.

4.5      Where CLEC purchases resale and elects to provide Directory Assistance
         and/or Operator Services to its customers through its own or a third
         party's Directory Assistance and/or Operator Services platforms, NEVADA
         will provide the functionality and features required to route calls
         from CLEC customers for local

                                      262
<PAGE>

                  Directory Assistance and/or Operator Services to CLEC
                  designated, dedicated trunks. Trunk signaling will be
                  appropriate to the technology used to provide access to CLEC's
                  Directory Assistance and/or Operator Services Platform. All
                  CLEC Directory Assistance and/or Operator Services trunk
                  group(s) will be dedicated and will not overflow to the NEVADA
                  network for call completion. A single customized routing
                  configuration will be provided for all of CLEC's customers in
                  an individual switch. Implementation of CLEC customized
                  Directory Assistance and/or Operator Services routing
                  arrangements will be on a project specific individual case
                  basis as mutually agreed by the Parties. Charges for dedicated
                  trunks are stated separately in Appendix PRICING.

5.       RESPONSIBILITIES OF NEVADA

5.1      NEVADA shall allow CLEC to place service orders and receive phone
         number assignments (for new lines). These activities shall be
         accomplished by facsimile or electronic interface when established.
         NEVADA, with input from CLEC, shall provide interface specifications
         for electronic access for these functions to CLEC once such electronic
         interfaces become technically feasible and are in place, However, CLEC
         shall be responsible for modifying and connecting any of its systems
         with NEVADA provided interfaces when such interfaces become available,
         as outlined in Appendix OSS.
5.2      NEVADA shall implement CLEC service orders within the same time
         intervals NEVADA uses to implement service orders for similar services
         for its own End Users.

          5.3 CLEC will have the ability to report trouble for its End Users to
          appropriate NEVADA trouble reporting centers twenty-four (24) hours a
          day, seven (7) days a week in the same manner as NEVADA provides for
          its End Users. CLEC will be assigned a customer contact center when
          initial service agreements are made. CLEC's End Users calling NEVADA
          will be referred to CLEC at the number provided by CLEC. NEVADA shall
          at all times be responsible for the repair and maintenance of its
          network. Nothing herein shall be interpreted to authorize CLEC to
          repair, maintain, or in any way touch NEVADA's network facilities,
          including those on End User premises.

         5.3.1    Methods and procedures for ordering and trouble reporting are
                  outlined in CLEC Handbook, as amended by NEVADA from time to
                  time. Both Parties agree to abide by the procedures contained
                  therein.
5.4      On no less than sixty (60) days advance written notice, CLEC may
         request NEVADA to make certain usage information available to CLEC on a
         daily basis in a standard electronic format as outlined in Appendix
         OSS. The information will consist of usage sensitive charges NEVADA
         will bill to CLEC arising out of

                                      263
<PAGE>

               the  -use of resold lines. CLEC agrees to pay NEVADA three tenths
                    of a cent ($.003) per message for this service.

5.5      NEVADA will notify CLEC of any changes in the price, terms and
         conditions under which NEVADA offers Telecommunications Services at
         retail to subscribers who are not telecommunications providers or
         carriers, including, but not limited to, the introduction of any new
         features, functions, services, promotions, grandfathering or the
         discontinuance of current features or services at the time a tariff
         filing is transmitted to the State Commission, or, in situations where
         a tariff filing is not so transmitted, within sixty (60) days
         (forty-five (45) days for price changes) of the expected effective date
         of such change. 5.5.1 NEVADA currently uses the Accessible Letter
         process to notify CLEC of
                  new services available for resale during the term of this
                  Agreement. The notification shall advise CLEC of the category
                  in which such new service shall be placed and the same
                  discount already applicable to CLEC in that category shall
                  apply to the new service. Should NEVADA change its
                  notification procedures to CLEC, the notice will be no less
                  prompt than the Accessible Letter.

5.6      CLEC End User's activation of Call Trace shall be handled by NEVADA.
         NEVADA shall notify CLEC of requests by its End Users to provide the
         call records to the proper authorities. Subsequent communication and
         resolution of the case with CLEC's End User (whether that End User is
         the victim or the suspect) will be coordinated through CLEC.

               5.6.1 CLEC understands that for services where reports are
                    provided to law enforcement agencies (e.g., Call Trace) only
                    billing number and address information shall be provided. It
                    shall be CLEC's responsibility to provide additional
                    information necessary for any police investigation. CLEC
                    shall indemnify NEVADA against any claims that insufficient
                    information led to inadequate prosecution. NEVADA shall
                    handle law enforcement requests consistent with the
                    Miscellaneous-Law Enforcement Section of the General Terms
                    and Conditions of this Agreement.

6.       RESPONSIBILITIES OF CLEC

          6.1 Prior to submitting an order under this Agreement, CLEC shall
          obtain End User

          authorization as required by applicable state or federal laws and
          regulations, and

         assumes responsibility for applicable charges as specified in Section
         258(b) of the Telecommunications Act of 1996. NEVADA shall abide by the
         same applicable laws and regulations.

                                      264
<PAGE>

               6.2  Only an End User can initiate a challenge to a change in its
                    local exchange service provider. If an End User notifies
                    NEVADA or CLEC that the End User requests local exchange
                    service, the Party receiving such request shall be free to
                    immediately provide service to such End User, except in
                    those instances where the end user's account is local PIC
                    protected. It is the responsibility of the end user to
                    provide written authorization to the current provider of
                    record to remove local service provider protection before
                    any changes in local exchange service provider are
                    processed.

         NEVADA shall be free to connect the End User to any local service
         provider based upon the local service provider's request and local
         service provider's assurance that proper End User authorization has
         been obtained. Both Parties shall make authorization available to the
         other Party upon request and at no charge.
6.3      When an End User changes or withdraws authorization, each Party shall
         release customer-specific facilities in accordance with the End User
         customer's direction or the direction of the End User's authorized
         agent. Further, when an End User abandons the premises, NEVADA is free
         to reclaim the facilities for use by another customer and is free to
         issue service orders required to reclaim such facilities.

6.4      Neither Party shall be obligated by this Appendix to investigate any
         allegations of unauthorized changes in local exchange service
         ("slamming") on behalf of the other Party or a third party. If NEVADA,
         on behalf of CLEC, agrees to investigate an alleged incidence of
         slamming, NEVADA shall charge CLEC a fifty dollar ($50) investigation
         fee.

               6.5  When NEVADA receives an order from CLEC for services under
                    this Appendix, and NEVADA is currently providing the same
                    services to another CLEC for the same End User, NEVADA shall
                    notify the End User's CLEC of record of such disconnect
                    activity, should CLEC subscribe to the Local Disconnect
                    Report ("LDR") as outlined below. It shall then be the
                    responsibility of the CLEC of record and CLEC to resolve any
                    issues related to the End User. This paragraph shall not
                    apply to new additional lines and services purchased by an
                    End User from multiple CLECs or from NEVADA.

          6.5.1 When available and on no less than sixty (60) days notice, CLEC
          may request the LDR. NEVADA agrees to furnish to CLEC the Billing
          Telephone Number ("BTN"), Working Telephone Number ("WTN"), and
          terminal number of all End Users who have disconnected CLEC's service.
          CLEC understands and agrees that such information will only be
          available electronically. Information will be provided on a per WTN
          basis to be priced on a per WTN basis. NEVADA will provide CLEC no
          less than thirty (30) days notice prior to any change of the per-WTN
          charge.

                  NEVADA grants to CLEC a non-exclusive right to use the
                  information provided by NEVADA. CLEC will not permit anyone
                  but its duly authorized employees or agents to inspect or use
                  this information. CLEC agrees to pay NEVADA ten cents ($0.10)
                  per WTN and any other applicable charges for the LDR as
                  outlined in this Appendix.

6.6      CLEC agrees to hold harmless and indemnify NEVADA against any and all
         liability and claims, including reasonable attorney's fees, that may
         result from NEVADA acting under this Appendix.
6.7      CLEC is solely responsible for the payment of charges for all services
         furnished under this Appendix including, but not limited to, recurring
         and nonrecurring charges, calls originated or accepted at CLEC's
         location and its End Users' service locations, with the exception of
         any retail services provided directly by NEVADA to the End User which
         NEVADA shall be responsible for billing.

 6.7.1   Interexchange carried traffic (e.g., sent-paid, information services
         and alternate operator services messages) received by NEVADA for
         billing to resold end-user accounts will be returned as unbillable and
         will not be passed on to CLEC for billing. An unbillable code returned
         with those messages to the carrier will indicate that the messages
         originated from a resold account and will not be billed by NEVADA.

 6.7.2   In accordance with industry standards, IXC PIC selections for lines
         resold to CLEC will not be processed from IXCs or End Users, but will
         only be processed if received from CLEC.

6.8      NEVADA shall not be responsible for the manner in which the use of
         resold service, or the associated charges are allocated to others by
         CLEC. All applicable rates and charges for such services will be billed
         to and shall be the responsibility of CLEC, with the exception of
         retail services provided directly to the End User by NEVADA.

6.8.1    Compensation for all services shall be paid regardless of a Party's
         ability or inability to collect charges from its End User for such
         service.

6.9      If CLEC does not wish to be responsible for collect, third number
         billed, toll, and information services (e.g., 900) calls, it must order
         the appropriate blocking for .resold lines under this Appendix and pay
         any applicable charges. Depending on the origination point, some calls
         may bypass the blocking systems. CLEC acknowledges this limitation and
         understands that CLEC is responsible for any charges associated with
         such calls. CLEC acknowledges that blocking is not available for
         certain types of calls, including 800/888 numbers.

<PAGE>

         6.10     CLEC shall be responsible for modifying and connecting any of
                  its systems with NEVADA provided interfaces as described in
                  this Appendix.

         6.11     CLEC shall be responsible for providing to its End Users and
                  to NEVADA a telephone number or numbers that CLEC's End Users
                  can use to contact CLEC in the event of service or repair
                  requests. In the event that CLEC's End Users contact NEVADA
                  with regard to such requests, NEVADA shall inform the End User
                  that they should call CLEC and may provide CLEC's contact
                  number. The requirements herein are subject to additional
                  terms and conditions in the Coordinated Repair Calls section
                  of the General Terms and Conditions of this Agreement.

7.       PROCEDURES FOR NONPAYMENT AND DISCONNECTION

7.1      If CLEC fails to pay when due (within 30 days of the bill date), any
         and all charges billed to them under this Appendix, including any late
         payment charges ("Unpaid Charges") or miscellaneous charges, and any
         portion of such charges remain unpaid more than fifteen (15) days after
         the due date of such Unpaid Charges, NEVADA shall notify CLEC in
         writing that in order to avoid having service disconnected, CLEC must
         remit all Unpaid Charges to NEVADA within fourteen (14) days.

7.2      If CLEC disputes the billed charges, it shall, within the fourteen (14)
         day period provided for above, inform NEVADA in writing which portion
         of the charges it disputes, including the specific details and reasons
         for its dispute; immediately pay to NEVADA all undisputed charges; and
         pay all disputed charges into an interest bearing escrow account.

7.3      Disputes hereunder shall be resolved in accordance with the procedures
         identified in the Dispute Resolution Section of the General Terms and
         Conditions of this Agreement. Failure of CLEC to pay charges deemed
         owed to NEVADA after conclusion of the Arbitration shall be grounds for
         termination under this Section.

7.4      If any CLEC charges remain unpaid or undisputed twenty-nine (29) days
         past the due date, NEVADA shall notify CLEC and the Commission in
         writing, that unless all charges are paid within sixteen (16) days,
         CLEC's service shall be disconnected and its End Users shall be
         defaulted to NEVADA's local service. NEVADA will also suspend order
         acceptance with the exception of disconnects on the same day that it
         sends the letter required by the preceding sentence.
7.5      If any CLEC charges remain unpaid or undisputed forty (40) days past
         the due date, CLEC shall, at its sole expense, notify its End Users and
         the Commission that their service may be disconnected for CLEC failure
         to pay Unpaid Charges, and that its End Users must affirmatively select
         a new local service provider

                                      267
<PAGE>

         within five (5) days. The notice shall also advise the End User that
         NEVADA will assume the End User's account at the end of the five (5)
         day period should the End User fail to select a new local service
         provider.

7.6      If any CLEC charges remain unpaid or undisputed forty-five (45) days
         past the due date, NEVADA shall disconnect CLEC and transfer all CLEC's
         End Users who have not selected another local service provider directly
         to NEVADA's service. These End Users shall receive the same services
         provided through CLEC at the time of transfer. NEVADA shall inform the
         Commission of the names of all End Users transferred through this
         process. Applicable service establishment charges for switching End
         Users from CLEC to NEVADA shall be assessed to CLEC.

7.7      Within five (5) days of the transfer (50 days past CLEC's due date),
         NEVADA shall notify all affected End Users that because of CLEC's
         failure to pay, their service is now being provided by NEVADA. NEVADA
         shall also notify the End User that they have thirty (30) days to
         select a local service provider, after which time should the End User
         not select a local service provider, the End User's service shall be
         terminated.

7.8      NEVADA may discontinue service to CLEC upon failure to pay undisputed
         charges as provided in this Section, and shall have no liability to
         CLEC or CLEC's End Users in the event of such disconnection.

         7.9      If any End User fails to select a local service provider
                  within thirty (30) days of the change of providers (80 days
                  past CLEC's due date), NEVADA shall terminate the End User's
                  service. NEVADA shall notify the Commission of the names of
                  all End Users whose service has been terminated. The End User
                  shall be responsible for any and all charges incurred during
                  the selection period.
         7.10     Nothing herein shall be interpreted to obligate NEVADA to
                  continue to provide service to any such End Users. Nothing
                  herein shall be interpreted to limit any and all disconnection
                  rights NEVADA may have with regard to such End Users.
         7.11     After disconnect procedures have begun, NEVADA shall not
                  accept service orders from CLEC until all unpaid charges are
                  paid. NEVADA shall have the right to require a deposit equal
                  to one month's charges (based on the highest previous month of
                  service from NEVADA) prior to resuming service to CLEC after
                  disconnect for nonpayment.

8.       INTERVENING LAW AND PRESERVATION OF RIGHTS

          8.1 At the time of execution of this Agreement, NEVADA is
          participating in Dockets before the Commission. The Parties have
          included certain rates, terms, and/or

                                      268
<PAGE>

         conditions in this Appendix which reflect rates, terms, and/or
         conditions established in Arbitration and contained in one or more
         agreements approved by the Commission. CLEC acknowledges that any
         negotiations, appeal, stay, injunction or similar proceeding impacting
         the applicability of those rates, terms or conditions to other CLECs
         will similarly impact the applicability of those rates, terms or
         conditions to CLEC (Collectively "Appeals"). If CLEC is not eligible to
         receive one or more rates, terms, or conditions at any time due to such
         Appeals, the Parties agree that NEVADA shall substitute the most
         favorable rate(s), terms, and conditions applicable to CLEC's
         activities then in place from an interconnection agreement which has
         been approved by the Commission.

8.2      Moreover, if the actions of Nevada or federal legislative bodies,
         courts or regulatory agencies of competent jurisdiction invalidate,
         modify or stay the enforcement of laws or regulations that were the
         basis for a provision of the contract which is reflective of the
         Consolidated Award, the affected provision shall be invalidated,
         modified or stayed. In such event, the Parties shall expend diligent
         efforts to arrive at an agreement respecting the modifications to the
         Agreement required. If negotiations fail, disputes between the Parties
         concerning the interpretation of the actions required or the provisions
         affected by such governmental actions shall be resolved pursuant to the
         Dispute Resolution process provided for in the General Terms and
         Conditions of this Agreement. NEVADA expressly reserves all of its
         appellate rights concerning the above Appeals and does not waive any
         legal arguments by executing this Appendix.

                          APPENDIX FOR THE PROVISION OF
                                   SS7 SERVICE

This Appendix sets forth the terms and conditions under which NEVADA shall
provide to CLEC certain Common Channel Signaling/Signaling System 7 ("CCS/SS7")
services, herein referred to as "SS7 Service".

This Appendix provides for the use of NEVADA's Common Channel Signaling network,
which uses the Signaling System 7 ("SS7") protocol, and for a Dedicated
Signaling Link, which provides network interconnection to NEVADA's Signal
Transfer Points ("STPs"), including facilities. SS7 Service provides CCS/SS7
functionality and translations to support SS7 based services and applications as
they become available and as facilities permit.

SS7 Service includes the screening of messages based on origination signaling
point code and the muting of messages by NEVADA's mated pair of STPs. Services
such as STP ports and Signaling Link interconnection, and 800 Data Base Access
will be provided pursuant to this Appendix SS7, Appendix 800, and Appendix
PRICING. Arrangements for services should be made through NEVADA's Service
Center.

1.       SERVICE DESCRIPTION

1.1      SS7 - Transport

 1.1.1   SS7 transport provides for the routing and screening of SS7 messages
         from NEVADA's pair of STPs (i.e. a mated pair) to a regional pair of
         STPs. The screening of messages provides for CLEC designation of
         signaling points associated with CLEC and controls which messages may
         be allowed or not allowed by NEVADA's ST? pairs. The routing of
         messages provides for the transfer of a complete message between
         signaling links, and for a Global Title Translation of the message
         address, if needed.

 1.1.2   SS7 transport provides routing of messages for all parts of the SS7
         protocol including, for example, Message Transfer Part ("MTP")
         messages, Integrated Services Digital Network User Part ("ISDNUP" or
         "ISUP") messages, Signaling Connection and Control Part ("SCCP")
         messages, and Transaction Capability Application Part ("TCAP")
         messages. SS7 transport provides for screening and routing of signaling
         messages based on the SS7

                                      303
<PAGE>

protocol. These messages may support other applications and services, such as,
Toll Free Database services. SS7 transport will route messages to the global
title address or to the signaling point code address of the message based on the
translation information of NEVADA's STP. These services are restricted to
NEVADA's existing database services.

         1.       1.3 SS7 transport provides screening and routing of messages
                  that are generated by the action of CLEC's signaling point, or
                  messages that are generated by a signaling point connected via
                  CLEC's signaling point.

1.2      Signaling Links

 1.2.1   Dedicated Signaling Links provide physical access to NEVADA's signaling
         network. The links are fully dedicated to the use of CLEC and provide
         the screening and routing usage for NEVADA's STP to which the link is
         connected. Signaling Links are provided as a set of links connecting to
         NEVADA's mated pair of STPs. Signaling Links are dedicated two-way
         digital data circuits that interconnect NEVADA's STP locations and
         CLEC's signaling points at Signaling Point of Interface ("SPOI")
         locations. Signaling links are available to CLECs for their use in
         furnishing SS7-based services or applications to their End Users or
         other users of SS7 signaling information.

1.2.2    Signaling links must include the following elements:

          1.2.2.1 Cross Connect

                    The Cross Connect provides a DS-0 connection and access
                    point for testing in NEVADA's ST? building. The cross
                    connect connects the STP Port Termination to CLEC's
                    unbundled dedicated transport, to a collocation cage or to a
                    STP Access Link. It must be purchased separately from
                    Appendix UNE.

          1.2.2.2 STP Port

                    The STP Port is the physical termination of the signaling
                    link (i.e. 56 kbps circuit) at NEVADA's STP. An STP Port is
                    used for each 56 kbps Cross Connect terminated at NEVADA's
                    STP.

                                      304
<PAGE>

1.2.2.3 SS7 Link

           The SS7 Link provides a 56 kilobit per second digital facility when
           CLEC requires an interoffice facility to connect from CLEC's
           Dedicated Transport or Entrance Facility to the STP building
           location.

 1.2.3 The STP Port shall provide for the use of NEVADA's STP to which the port
is connected.

 1.2.4   CLEC shall provide the portion of the signaling link from CLEC's
         premises within the LATA to NEVADA's STP location using unbundled
         dedicated transport, or the optional bundled SS7 link and STP port.
         CLEC shall notify NEVADA that the facility contains a signaling link
         service. Multiple facilities provided by NEVADA will be identified so
         that NEVADA may maintain facility diversity between links and linksets
         that require diversity. CLEC shall identify the DS-1 and the channel of
         a DS-1 that will be used for the signaling link.

 1.2.5   CLEC shall identify to NEVADA the facility and channel to which the SS7
         Link Cross Connect shall connect. If the facility does not terminate in
         the STP location NEVADA shall provide a STP Link. The STP Access Link
         will connect to the DS-0 Cross Connect at the STP location.

 1.2.6   When CLEC uses an alternative DS-1 facility or arrangements, or agrees
         to allow a physical degree of diversity or performance that is not in
         accordance with the specifications of Bellcore, GR-905-CORE, NEVADA
         acknowledges that the performance and reliability of the SS7 protocol
         may be affected and the performance and reliability standards described
         in GR-905-CORE may be disqualified.

 1.2.7   Signaling links are subject to NEVADA interoperability testing and
         certification requirements per the Network Operations Forum Reference
         Document, per Bellcore, GR-905-CORE and per (PUB L-780023-PB/NB). First
         interconnections to NEVADA's signaling network per CLEC and per
         signaling point type of equipment will require CLECs completion of
         NEVADA's CCS/SS7 interconnection questionnaire and pre-ordering
         meetings to exchange information and schedule inter-operability testing
         and pre-ordering meetings.

                                      305
<PAGE>

          1.3     Transit Signalin

                  Transit signaling will provide the ability for an
                  Interconnecting Network ("ICY) to pass signaling information
                  through NEVADA's signaling network to a third party without
                  requiring a trunking connection by the third party with
                  NEVADA. The ICN will not be required to purchase signaling
                  links to the third party. Instead, the ICN will provide NEVADA
                  with information necessary to complete local calls.

2.       DEFINITIONS

2.1      Common Channel Signaling ("CCS")
         A high-speed specialized packet switched communications network that is
         separate (out-of-band) from the public packet switched and message
         networks. CCS carries addressed signaling messages for individual trunk
         circuits and/or database related services between Signaling Points (SS7
         nodes) in the CCS network.


2.2      Interoperability Testin
         Testing performed by representatives from NEVADA and CLEC to determine
         proper interconnection of CCS network facilities for accurate
         transmission of system signals and messages. This is often referred to
         as TR-905 Compatibility Testing.

2.3      Octet
         8-bits of binary information.

2.4      Service Control Point ("SCP")
         A node in the CCS network that provides a database functionality.

2.5      Service Switching Point ("SSP")
         A signaling point that can launch queries to databases and
         receive/interpret responses used to provide specific End User services.

2.6      Signal Transfer Point ("STP")
         A packet switch in the CCS network that is used to route SS7 protocol
         signaling messages between signaling nodes. A STP provides screening
         and routing of SS7 messages. STPs transfer signaling messages to other
         networks. NEVADA's signaling network includes mated pairs of local and
         regional STPs.

2.7      Signaling Link
         An end-to-end high-capacity digital, data quality, link operating at 56
         kilobits per second that transmits signaling information in the form of

                                      306
<PAGE>

signaling messages from one network SS7 node to another node in a CCS network.
The Link Type identifies the functionality of the signaling link sets. Signaling
links provide physical interconnection between signaling points of another party
and NEVADA's STPs.

2.8      Signaling Point ("SP")

         A node in the CCS network that originates and/or receives signaling
         messages, or transfers signaling messages from one signaling link to
         another, or both.

2.9      Signaling Point Code ("SPC")

         An identifier code that identifies a signaling point in the CCS
         network. The signaling point code provides an address within the CCS
         network which enables messages to be routed to signaling points.
         Signaling Point Codes are 24-bit binary numbers comprised of three
         segments:

(a)      the Network Identification;


(b)      the Network Cluster; and

(c)      the Member number within the cluster.

Signaling Point Codes are represented digitally as AAA-AAA-AAA, where "AAA"
represents a decimal number from 000 to 255.

2.10     Signaling Point of Interface ("SPOI")

         A mutually agreed point at which NEVADA hands off signaling

         information to CLEC.

2.11     Signaling System 7 ("SS7")

         See SS7 Protocol.

2.12     Signaling System 7 ("SS7") Protocol

         The signaling protocol, Version 7, used by the nodes of the CCS
         network. The SS7 protocol used by NEVADA is the American National
         Standards Institute ("ANSI") standard protocol defined by Bellcore
         Generic Requirement, GR-246-CORE, defined by Bellcore requirements

3.       MANNER OF PROVISIONING

         3.1      SS7 Transport

                  3.1.1    CLEC shall use SS7 transport subject to the screening
                           and routing information of NEVADA's STPs. NEVADA
                           shall provide information to CLEC on the routes and
                           signaling point codes served by NEVADA's STPs.

                  3.1.2    SS7 transport shall route ISUP messages for the
                           purpose of establishing trunk voice paths between
                           switching machines.

               3.1.3 CLEC shall route TCAP to NEVADA's "regional" ST? pair that
                    directly serves the database of TCAP messages.

                  3.1.4    When CLEC requires modification of NEVADA's SS7
                           Service components not otherwise provided in this
                           Appendix, the modifications may be furnished pursuant
                           to the Network Element Bona Fide Request ("BFR")
                           process as outlined in Appendix UNE.

                  3.1.5    SS7 transport provides a signaling route for messages
                           only to signaling points to which NEVADA has a route.
                           SS7 Transport does not include the provision of a
                           signaling route to every possible signaling point.
                           When NEVADA does establish a route to a signaling
                           point in a mated pair of STPs, the route may not be
                           available to other NEVADA pairs of STPs, until
                           ordered. When NEVADA or CLEC, pursuant to a service
                           order, arranges to establish a route to a signaling
                           point, such route to the other signaling point or
                           other signaling network will be used by all signaling
                           points within and connected to NEVADA's signaling
                           network per the standard requirements of the SS7
                           protocol.

                  3.1.6    Disputes concerning the association of a signaling
                           point among specific link sets associated with
                           NEVADA's mated STP will be resolved by consultation
                           with the signaling point owner, as defined in the
                           Local Exchange Routing Guide ("LERG"), Section 1,
                           Assignment of Signaling Point Codes.

         3.2      Signaling Links

               3.2.1 CLEC shall provide the signaling points and signaling point
                    codes associated with CLEC. CLEC shall provide information
                    to NEVADA to allow NEVADA to translate NEVADA STPs. The

                                      308
<PAGE>

information shall define the screening and routing information for the signaling
point codes of CLEC. This information may include global title address,
translation type and subsystem designations as needed.

 3.2.2   NEVADA mated pairs of STPs shall connect to CLEC premises (including
         collocation locations) within the same LATA. A set of links can be
         either:

(a)      "A" Link Sets from CLEC's Signaling Point ("SP")/Service

         Switching Point ("SSP"). A minimum of two links will be
         required, one from the SP/SSP to each STP; or,

(b)      "B/D" Link Sets from STPs that are connected to

         NEVADA's mated pair of STPs. A minimum of four links will be required
         (i.e., a "quad") between the two pairs of STPs. When CLEC provides its
         own channelized facility, an ST? Port and Cross Connect is required for
         each 56 kbps access link utilized for the Service. STP locations are
         set forth in the National Exchange Carrier Association, Inc. ("NECA")
         Tariff FCC No. 4.

3.3      A pre-order meeting will define NEVADA's facility availability and the
         degree of diversity in both NEVADA's physical network and CLEC's
         physical network from signaling point to signaling point for the link.

3.4      When CLEC requires an SS7 Link, CLEC and NEVADA shall jointly
         negotiate the degree of diversity provided among and between multiple
         dedicated signaling links. The degree of diversity in both NEVADA's
         network and CLEC's network shall be exchanged. The negotiation shall
         consider the requirements of the SS7 standard protocol, the degree of
         diversity available in each network and the possible alternatives. If
         CLEC
         requires a degree of diversity greater than is available in NEVADA's
         network, CLEC shall submit a BFR.

3.5      All applicable signaling point codes for each signaling link must be
         installed at each of NEVADA's interconnecting STPs.

3.6      Call set-up times may be adversely affected when CLEC, using SS7
         signaling, employs intermediate Access Tandems in its network. NEVADA
         makes no warranties with respect to call set-up times when multiple STP
         pairs are involved or when the signaling traffic is exchanged between
         two non-NEVADA signaling points.

                                      309
<PAGE>

3.7      Provisioning of the SS7 Service is in accordance with NEVADA's CCS/SS7
         Network Interface Specifications (PUB L780023-PB/NB) and Bellcore
         Common Channel Network Interface Specification (GR-905- CORE),
as amended.

3.8      When CLEC uses the SS7 Links of another party (the Signaling Service
         Provider), CLEC shall submit a Shared Service Agreement to NEVADA. The
         Signaling Service Provider shall also submit an order for NEVADA to
         change the routing or screening information associated with its
         signaling links.

         will remain the property of NEVADA.

2.9      Access to Unbundled Network Elements
         This Section 2.9 describes the methods under which NEVADA agrees to
         provide CLECs with access to NEVADA's UNEs and the conditions under
         which NEVADA makes these methods available. The methods listed below
         provide CLEC with access to UNEs without compromising the security,
         integrity, and reliability of the Public Switch Network, as well as to
         minimize the potential service disruptions.

2.9.1    Subject to availability of space and equipment, CLEC may use the
         methods listed below to access and combine identified Unbundled
         Network Elements within NEVADA central offices or tandem offices. The

                                      319
<PAGE>

methods listed below provide access on an unbundled basis to loop, switch ports,
and dedicated transport.

2.9. 1.1 (Method 1)

           If a CLEC is physically collocated, NEVADA will extend UNEs that
           require cross connection to CLEC's physical collocation Point of
           Termination (POT) frame.

2.9.1.2 (Method 2)

           If CLEC is physically collocated, NEVADA will extend UNEs that
           require cross connection to the UNE Frame located in a collocation
           common area.

2.9.1.3 (Method 3)

           NEVADA will extend UNEs that require cross connection to the UNE
           Frame located in a common room space, other than collocation common
           area, within the central office building.

2.9.1.4 (Method 4)

           NEVADA will extend UNEs to an external Point of Presence, such as a
           cabinet located outside the central office building provided by
           NEVADA on NEVADA property. CLEC will be afforded access to this
           arrangement through the UNE order process.

2.9.1.5 (Method 5)

           NEVADA shall allow extension of UNEs to a building not controlled by
           NEVADA via cabling provided by CLEC. The CLEC shall provide the

              incurred by NEVADA associated with the preparation of the building
              to provide access to Unbundled Network Elements in the initial
              space where access to Unbundled Network Elements is to be located
              ("Initial Common Charge"). Thereafter the Initial Common Charge
              will be prorated and the prorated share refunded to the previous
              CLEC(s) as additional entities use access to Unbundled Network
              Elements in the building within twelve (12) months of the first
              billing date of the initial monthly charge for the first CLEC in
              the building, using the following

              schedule:

     CLEC               Initial Common Charge              Refund

2.10     Additional Network Elements

 2-10.1  Various subsections below list the Unbundled Network Elements that CLEC
         and NEVADA have identified as of the Effective Date of this Agreement.
         Upon request, NEVADA will provide access to additional Unbundled
         Network Elements or modifications to previously identified Unbundled
         Network Elements for the provision by CLEC of a Telecommunications
         Service. Such requests shall be processed in accordance with the Bona
         Fide Request process as described in Section 2.13 below.

               2.10.2 NEVADA will provide access to network elements on an
                    unbundled basis where technically feasible. Where facilities
                    and equipment are not available, NEVADA shall not be
                    required to provide UNEs. Provided however, CLEC may request
                    and NEVADA may agree, at its sale discretion, to provide
                    Unbundled Network Elements, even where facilities do not
                    exist, through the Bona Fide Request process.

2.11     Provisioning/Maintenance Of Network Elements

 2.11.1  Access to Unbundled Network Elements are provided under this agreement
         over such routes, technologies, and facilities as NEVADA may elect at
         its own discretion. If CLEC requests special facilities, equipment or
         routing of Unbundled Network Elements, such requests will be handled
         under the Bona Fide Request process.

 2.11.2  Subject to the terms herein, NEVADA is responsible only for the
         installation, operation and maintenance of the Network Elements it
         provides. NEVADA is not otherwise responsible for the
         Telecommunications Services provided by CLEC through the use of those
         elements.

 2.11.3  Where unbundled elements provided to CLEC are dedicated to a single End
         User, if such elements are for any reason disconnected they will be
         made available to NEVADA for future provisioning needs, unless such
         element is disconnected in error. CLEC agrees to relinquish control of
         any such unbundled element concurrent with the disconnection of CLEC's
         End User service.

2.11.4   CLEC shall make available at mutually agreeable times the elements
         provided pursuant to this Appendix in order to permit NEVADA to make
         tests and adjustments appropriate for maintaining the elements in

                                      324
<PAGE>

          satisfactory operating condition. No credit will be allowed for any
          interruptions involved during such testing and adjustments.

2.1      1.5 CLEC's use of any NEVADA network element, or of its own equipment
         or facilities in conjunction with any NEVADA network element, will not
         materially interfere with or impair service over any facilities of
         NEVADA, its affiliated companies or its connecting and concurring
         carriers involved in its services, cause damage to their plant, impair
         the privacy of any communications carried over their facilities or
         create hazards to the employees of any of them or the public. Upon
         reasonable written notice and opportunity to cure, NEVADA may
         discontinue or refuse service if CLEC violates this provision, provided
         that such termination of service will be limited to CLEC's use of the
         element(s) causing the violation.

2.11.6 When a NEVADA provided tariffed or resold service is replaced by CLEC's
     facility based service using any NEVADA provided Unbundled Network Elements
     (including service provided exclusively via NEVADA provided UNE(s)), CLEC
     shall issue appropriate service requests in accordance with OBF guidelines,
     to both disconnect the existing service and new connect service to CLEC's
     End User. These disconnect/new connect requests will be processed by
     NEVADA, and CLEC will be charged the applicable UNE service order
     charge(s). Similarly, when an End User is served by one CLEC using NEVADA
     provided UNEs, the requesting CLEC shall issue appropriate service requests
     in accordance with OBF guidelines to both disconnect the existing service
     and new connect service to the requesting CLEC's End User. These
     disconnect/new connect requests will be processed by NEVADA and CLEC will
     be charged the applicable service order charge(s).

2.11.7   Unbundled Network Elements may not be connected to or combined with
         NEVADA access services or other NEVADA tariffed service offerings with
         the exception of tariffed collocation services.

2.12     Performance of Network Elements

         Nothing in this Agreement will limit either Party's ability to modify
         its network through the incorporation of new equipment, new software or
         otherwise. Each Party will provide the other Party written notice of
         any such upgrades in its network which will materially impact the other
         Party's service consistent with the timelines established by the FCC in
         the Second Report and Order, CC Docket 96-98. CLEC will be solely
         responsible, at its own expense, for the overall design of its
         telecommunications services and for any redesigning or rearrangement of
         its telecommunications; services which may be required because of
         changes in

                                      325
<PAGE>

facilities, operations or procedure of NEVADA, minimum network protection
criteria, or operating or maintenance characteristics of the facilities.

2.13 Bona Fide Request

         Various sections below identify specific Unbundled Network Elements and
         provide the terms and conditions on which NEVADA will offer them to
         CLEC. Any request by CLEC for an additional Unbundled Network Element,
         or modifications to previously identified Network Elements, may be
         considered under this Bona Fide Request ("BFR") process, also known as
         the Interconnection and Network Element Request ("MR") process. Where
         facilities and equipment are not available, CLEC may request and NEVADA
         may, at its sole discretion, agree to provide Network Elements through
         the BFR process.

2.13.1 Each Party will promptly consider and analyze access to new Unbundled
     Network Element(s) with the submission of a Network Element Bona Fide
     Request hereunder. The Network Element Bona Fide Request process set forth
     herein does not apply to those services requested pursuant to Report &
     Order and Notice of Proposed Rulemaking 91-141 (reel. Oct. 19, 1992)
     paragraph 259 and n. 603 and subsequent rulings.

 2.13.2     A Network Element Bona Fide Request will be submitted in writing and
            will include an adequate technical description of each requested
            Network Element to determine technical feasibility and development
            requirements, the date when interconnection is requested and the
            projected quantity of interconnection points ordered with a demand
            forecast.

 2.13.3     The requesting Party may cancel a Network Element Bona Fide Request
            at any time, but will pay the other Party's reasonable and
            demonstrable costs of processing and/or implementing the Network
            Element Bona Fide Request up to the date of cancellation.

 2.13.4     Within ten (10) business days of its receipt, the receiving Party
            will acknowledge receipt of the Network Element Bona Fide Request.

 2.13.5     Except under extraordinary circumstances, within forty-five (45)
            days of its receipt of a Network Element Bona Fide Request, the
            receiving Party will provide to the requesting Party a preliminary
            analysis of such Network Element Bona Fide Request. The preliminary
            analysis will confirm that the receiving Party will offer access to
            the Network Element or will provide a detailed explanation that
            access to the Network Element is not technically feasible and/or
            that the request does

                                      326
<PAGE>

not qualify as a Network Element that is required to be provided under the Act.

2.13.6     If the receiving Party determines that the Network Element Bona Fide
           Request is technically feasible and otherwise qualifies under the
           Act, it will promptly proceed with developing the Network Element
           Bona Fide Request upon receipt of written authorization from the
           requesting Party. When it receives such authorization, the receiving
           Party shall promptly develop the requested services, determine their
           availability, calculate the applicable prices and establish
           installation intervals.

 2.13.7     Unless the Parties otherwise agree, the Network Element Bona Fide
            Request must be priced in accordance with Section 252(d)(1) of the
            Act.

 2.13.8     As soon as feasible, but not more than ninety (90) days after its
            receipt of authorization to proceed with developing the Network
            Element Bona Fide Request, the receiving Party shall provide to the
            requesting Party a Network Element Bona Fide Request quote which
            will include, at a minimum, a description of each Network Element,
            the availability, the applicable rates and the installation
            intervals.

2.13.9     Within thirty (30) days of its receipt of the Network Element Bona
           Fide Request quote, the requesting Party must either confirm its
           order for the Network Element Bona Fide Request pursuant to the
           Network Element Bona Fide Request quote, or cancel the Network
           Element Bona Fide Request and pay the costs of the receiving Party
           pursuant to Section 2.13.3 above, or seek arbitration by the
           Commission pursuant to Section 252 of the Act.

                  2.13.10    If a Party to a Network Element Bona Fide Request
                             believes that the other Party is not requesting,
                             negotiating or processing the Network Element Bona
                             Fide Request in good faith, or disputes a
                             determination, or price or cost quote, such Party
                             may seek mediation or arbitration by the Commission
                             pursuant to Section 252 of the Act.

3.       NETWORK INTERFACE DEVICE

CLEC may connect its local loops to customer's inside wiring through NEVADA's
NID and an adjoining NID deployed by requesting carrier (47 CFR Section
51.319(b)(2)).

 3.1      The Network Interface Device ("NID") is a cross-connect used to
          connect loop facilities to inside wiring. The fundamental function of
          the NID is to establish the official network demarcation point between
          a carrier and its end-user customer. The NID contains the appropriate
          and accessible connection points or posts to

                                      327
<PAGE>

          which the service provider and the end-user customer each make its
          connections. (Note: If CLEC purchases a NEVADA Loop, a separate NID
          will not be required.)

3. 1.1 Under this Agreement, NEVADA shall offer two general types of NIDs:

3.1.1.1 Simple NID

           A Simple NID is a standard network interface ("SNI") the use of which
           permits the End User's inside wiring to be isolated from NEVADA's
           network.

3.1.1.2 Complex NID

           A Complex NID is a building terminal where an End User's inside
wiring terminates on NEVADA's network.

3.2      CLEC will provide its own NID and will interface to the customer's
         premises wiring through connections in the customer chamber of the
         NEVADA NID.

3.3      Unless requested by CLEC, no coordination is provided. If CLEC requests
         coordination, Additional Labor Billing charges will be applied if
         NEVADA incurs these costs as a result of CLEC request, as specified in
         NEVADA's tariff P.S.C.N. C, Section 13. In addition, unless otherwise
         agreed by CLEC and NEVADA, neither Party shall access the network side
         of the other Party's ND:) unless the owning Party's service technician
         is present, or unless the owning Party has already made the necessary
         modifications to isolate its network.

3.3.1    Upon request, NEVADA will dispatch a technician to tag the End User's
         inside wire facilities on the End User's side of the NID. In such
         cases, a Premise Visit charge shall apply as specified in Appendix
         PRICING, as a Dispatch without Installation of NID.

3.4      The NEVADA NIDs that CLEC uses under this Appendix will be existing
         NIDs installed by NEVADA to serve its customers.

3.5      CLEC shall not attach to or disconnect NEVADA's ground. CLEC shall not
         cut or disconnect NEVADA's loop from its protector. CLEC shall not cut
         any other leads in the NID. CLEC shall protect all disconnected leads
         with plastic sleeves and will store them within the NID enclosure. CLEC
         shall tighten all screws or lugs loosened by CLEC in the NID's
         enclosure and replace all protective covers.

                                      328

4.       LOCAL LOOP/LINK

4.1      A "loop" (a.k.a. Link) is a dedicated transmission facility between a
         distribution frame (or its equivalent) in a NEVADA central office and
         an End User customer premises. (47 CFR Section 51.319(a)) (Note: If
         CLEC purchases a NEVADA Loop, a separate NID will not be required).

4.2  NEVADA will provide at the rates, terms, and conditions set out in Appendix
     PRICING the following types of Loops:

4.2.1    2-Wire Analog Loop
         A 2-Wire Analog Loop supports analog voice frequency, voice band
         services with loop start signaling with the frequency spectrum of
         approximately 300 Hz and 3000 Hz.

4.2.1.1      NEVADA will offer 5dB conditioning on a 2-Wire Analog Loop as the
             standard conditioning option available for ground start signaling
             and Reverse Battery.

4.2.2    4-Wire Analog Loop
         A 4-Wire Analog Loop provides a non-signaling voice band frequency
         spectrum of approximately 300 Hz to 3000 Hz. The 4-Wire Analog Loop
         provides separate transmit and receive paths.

4.2.3    2-Wire Digital Loop
         A 2-Wire Digital Loop supports Basic Rate ISDN ("BRI") digital
         services. The 2-Wire Digital Loop supports usable bandwidth up to 160
         Kbps.

4.2.3.1     A Facility(ies) Request Form must be processed by NEVADA for each
            new 2-Wire Digital Loop ordered to assure the facilities meet the
            parameters specified for such loop type. The Facility Request Form
            rate will be billed to CLEC as displayed in Appendix PRICING for
            each loop analyzed.
4.2.3.2     If the results of the Facility(ies) Request analysis indicates that
            special conditioning (i.e., add mid-span repeater) is required to
            meet the parameters for this type of Loop, CLEC will be notified
            before commencement of the work. If CLEC authorizes the installation
            of the loop conditioning, CLEC will be billed the ISDN loop
            conditioning charge(s) as displayed in Appendix

                                      329
<PAGE>

PRICING i addition to normal monthly and nonrecurring charges for the loop.

         4.2.4 4-Wire Digital Loop

          A 4-Wire Digital Loop supports DS-1 digital services including Primary
          Rate ISDN ("PRI"). The 4-Wire Digital Loop supports usable bandwidth
          up to 1.544 Mbps.

4.3  CLEC may request additional loop types and conditioning pursuant to the
     Bona Fide Request process.

4.4  If CLEC requests one or more unbundled Loops serviced by Integrated Digital
     Loop Carrier ("IDLC") NEVADA will, where available, move the requested
     unbundled Loop(s) to a spare, existing physical or a universal digital loop
     carrier unbundled Loop at no additional charge to CLEC. If, however, no
     spare unbundled Loop is available, NEVADA will within two (2) business
     days, excluding weekends and holidays, of CLEC's request, notify CLEC of
     the lack of available facilities. CLEC may request alternative arrangements
     through the Bona Fide Request process.

4.5      Project Service Coordination

         The following coordination procedures apply only to Loops ordered as a
         project (seven (7) or more lines to a single End User's Minimum Point
         of Entry ("MPOE") at locations where cutover coordination is related:

4.5.1    On each Loop order in a Wire Center, CLEC will contact NEVADA and the
         Parties will agree on a cutover time at least two (2) business days
         before that cutover time. The cutover time will be defined as a half
         (1/2) hour window (normally provisioned from 8 am. to 5 p.m. Monday
         through Friday), within which both CLEC and NEVADA personnel will make
         telephone contact to begin the cutover activity. Coordination for Loops
         meeting the definition of a project will be provided by the Parties at
         no charge unless NEVADA incurs additional costs to accommodate CLEC's
         request. Cutover activity which is requested to take place outside of
         normal business hours (8 a.m. to 5 p.m. Monday through Friday) will be
         billed as described in NEVADA's Tariff P.S.C.N. C, Section 13.

4.5.2    Within the appointed half (1/2) hour cutover time, CLEC will call
         NEVADA's Local Operations Center ("LOC"), and when the LOC is reached
         in that interval, such work will begin. If CLEC fails to call or is not
         ready within the appointed interval, and if CLEC had not called to
         reschedule the work at least two (2) hours prior to the start of the
         interval,

                                      330
<PAGE>

                  CLEC and NEVADA will reschedule the work. order on a mutually
                  negotiated basis and CLEC will pay the Service Date Change
                  charge as set forth in NEVADA's Tariff P.S.C.N. C, Section 5
                  to reschedule the appointment.

         4.5.3    If NEVADA's LOC is not available or ready when CLEC calls
                  during the half (1/2) hour interval, NEVADA will not bill the
                  Service Date Change charge for the Loop or Loops scheduled for
                  that interval and will reschedule the installation on a
                  mutually negotiated basis.

4.6      Forecasts

         For the first six (6) months after CLEC's first order for a Loop, CLEC
         shall provide to NEVADA forecasts of the number of loops at the LATA
         level. Thereafter, CLEC shall make a good-faith effort to provide such
         forecasts to NEVADA at a Wire Center level. This includes associated
         additional line ("ADL") requirements when NEVADA's primary residential
         POTS service is not to be disconnected in the establishment of loop
         service. CLEC shall provide such

         forecasts to NEVADA on a semi-annual basis.

5.       LOCAL SWITCHING

5.1  The local switching element encompasses line-side and trunk-side facilities
     plus the features, functions and capabilities of the switch. The line side
     facilities include the connection between a loop termination at, for
     example, a main distribution frame ("MDF"), and a switch line card.
     Trunk-side facilities include the connection between, for example, hunk
     termination at a trunk-side cross connect panel and a trunk card. The local
     switching element includes all features, functions, and capabilities of the
     local switch, including but not limited to the basic switching function of
     connecting lines to lines, lines to trunks, trunks to lines and trunks to
     trunks. It also includes the same basic capabilities that are available to
     NEVADA customers, such as a telephone number and dial tone. In addition,
     the local switching element includes access to features that NEVADA uses or
     is authorized to use in that switch, including Custom Calling, CLASS
     features, and Centrex-like capabilities.

 5.2     Until such time that a CLEC purchases unbundled Local Switching and
         elects to provide customized routing for local calls to its customers,
         NEVADA will route local calls as defined by the exchange dialing plan.
         Where CLEC elects to provide customized routing for local calls, NEVADA
         will provide the functionality and features required to route all
         multiple switch local calls from CLEC End Users to CLEC designated,
         dedicated trunks. Intraswitch local calls will continue to be routed
         via NEVADA intraoffice facilities. CLEC custom routed local calls will
         be routed based on the class of call. All CLEC Local Interconnection
         Trunk Group(s) are dedicated and will not overflow to the

                                      331
<PAGE>

NEVADA network for call completion. A single customized routing configuration
will be provided for all of CLEC's customers in an individual switch.
Implementation of CLEC customized local interconnection routing arrangements
will be on a project-specific basis as mutually agreed by the Parties.

 5.2.1   An End Office Dedicated DS-1 Trunk Port provides CLEC with dedicated
         hunk access on NEVADA's trunk side of an End Office Switch at a DS-1
         level.

 5.2.2   A Tandem Dedicated DS-1 Trunk Port provides CLEC with dedicated trunk
         access on NEVADA's trunk side of a Tandem Switch at a DS-1

         level.

5.3      When CLEC uses unbundled Local Switching, NEVADA will route interLATA,
         interstate and international calls via CLEC End User's presubscription
         or casually dialed interLATA carrier. Until such time that intraLATA
         presubscription is deployed in conjunction with interLATA relief,
         NEVADA will route intraLATA toll calls as defined by the exchange
         dialing plan when CLEC uses Local Switching elements. When intraLATA
         presubscription is deployed, NEVADA will route intraLATA toll calls to
         CLEC End User's presubscribed or casually dialed intraLATA carrier.

 5.4 When CLEC purchases unbundled Local Switching, NEVADA's Local Switching
element will route:

(a)  local calls on NEVADA's shared network to the appropriate trunk or lines
     for call origination or termination; and

(b)  toll calls on NEVADA's common network to the appropriate trunk or lines for
     call origination or termination.

5.5      Where CLEC purchases unbundled Local Switching ("ULS") and elects to
         provide Directory Assistance and/or Operator Services to its customers
         through its own or third party Directory Assistance and/or Operator
         Services platforms, NEVADA will provide the functionality and features
         required to route calls from CLEC customers for local Directory
         Assistance (i.e., DA calls dialed within the customer's NPA) and/or
         Operator Services to CLEC designated, dedicated trunks for the
         provision of CLEC Directory Assistance and/or Operator Services as
         agreed to by the Parties.

 5.5.1   Trunk signaling will be appropriate to the technology used to provide
         access to CLEC Directory Assistance and/or Operator Services Platform.
         All CLEC Directory Assistance and Operator Services trunk group(s) will
         be dedicated final and will not overflow to NEVADA's network for call

                                      332
<PAGE>

completion. A single customized routing configuration will be provided for all
of CLEC's customers in an individual switch. Implementation of CLEC customized
Directory Assistance and/or Operator Services routing arrangements will be on a
project-specific basis as mutually agreed by the Parties.

         5.5.2    Charges are dependent upon switch type and include Switching
                  Establishment in addition to the Customized Routing charges to
                  be determined on a project specific basis outlined in Section
                  5.2 above.

5.6  NEVADA will provide the Local Switching element only with standard central
     office treatments (e.g., busy tones, vacant codes, fast busy, etc.),
     supervision and announcements.

5.7      NEVADA will control congestion points such as those caused by radio
         station call-ins, and network routing abnormalities, using capabilities
         such as Automatic Call Gapping, Automatic Code Gapping, Automatic
         Congestion Control, and Network Routing Overflow. CLEC agrees to
         respond to NEVADA's notifications regarding network congestion.

5.8      NEVADA will provide switch interfaces to adjuncts in the same manner it
         provides them to itself CLEC requests for use of NEVADA's adjuncts will
         be handled through the Bona Fide Request process.

5.9      In ordering BILLS, CLEC will designate the features and functions that
         are to be activated on a particular unbundled switch port. NEVADA will
         provide features to the extent such features and functions are
         available or as may be requested by the Bona Fide Request process.

5.10.    Switch Ports

          5.10.1 Analog Line Port

                   An Analog Line Port is a line side switch connection
                   available in either a loop or ground start signaling
                   configuration used primarily for Switched voice
                   communications.

                  CLEC shall provide to NEVADA forecasts of the number of such
                  unbundled Switch Port arrangements (quantities of lines and
                  trunks) at an End Office level. Thereafter, CLEC shall provide
                  such forecasts to NEVADA on a semi-annual basis.

6.       TANDEM SWITCHING

6.1      Tandem Switching is defined as:

(a)      trunk-connect facilities, including but not limited to the connection

         between trunk termination at a cross-connect panel and a switch trunk
         card;

(b)      the basic switching function of connecting trunks to trunks; and

(c)      all technically feasible functions, that NEVADA uses or is authorized
to

         use, that are centralized in tandem switches (as distinguished from

                                      334
<PAGE>

                           separate end-office switches), including but not
                           limited to call routing, call recording, and
                           signaling conversion features.

12.      PRICING

 12.1    Attached hereto as Appendix PRICING is a schedule which reflects the
         prices at which NEVADA agrees to provide CLEC with access to Unbundled
         Network Elements. CLEC agrees to compensate NEVADA for Unbundled
         Network Elements at the terms and conditions contained in this
         Appendix. Unbundled Network Elements are available from NEVADA on a per
         Unbundled Network Element basis at prices as contained in Appendix
         PRICING.

          12.1.1  For any rate element and/or charge contained in or referenced
                  to in this Appendix that are not listed in the attached
                  Appendix PRICING, including Bona Fide Requests, NEVADA and
                  CLEC will negotiate prices.

12.2     Unless otherwise stated, NEVADA will render a monthly bill for Network
         Elements provided hereunder. Remittance in full will be due within
         thirty (30) days of receipt of invoice. Interest will apply on overdue
         amounts.

12.3     Recurring Charges

12.3.1 Unless otherwise listed below, where Rates are shown as monthly, a month
     will be defined as a calendar month. The minimum term for each monthly
     rated element will be one (1) month. After the initial month, billing will
     be on the basis of whole or fractional months used. The

                                      338
<PAGE>

         minimum service period for elements provided under the Bona Fide
Request process may be longer.

 12.3.2  Where rates are based on minutes of use, usage will be accumulated at
         the end office or other measurement point without any per call rounding
         and total minutes by end office are rounded to the next higher minute.
         CLEC shall pay for all usage on such calls including those that are not
         completed due to busy or don't answer conditions.

12.3.3 Where rates are based on miles, the mileage will be calculated on the
     airline distance involved between the locations. To determine the rate to

         be billed, NEVADA will first compute the mileage using the V&H

         coordinates method, as set forth in the National Exchange Carrier
         Association, Inc. Tariff FCC No 4. When the calculation results in a
         fraction of a mile, NEVADA will round up to the next whole mile before
         determining the mileage and applying rates.


12.4     Nonrecurring Charges

 12.4.1  Consistent with CFR 51.307(d), there are nonrecurring charges for each
         Unbundled Network Element on the first connection on a CLEC order as
         well as separate nonrecurring charges for each additional connection
         associated with the same CLEC order at the same CLEC specified
         premises.

12.4.2   The appropriate nonrecurring charges shall apply for each service
         request processed by NEVADA, including but not limited to the
         following:

(a)      installation (Service Order and Connect);

(b)      disconnection (Disconnect);

<PAGE>

12.5.2   If trouble occurs with Unbundled Network Elements provided by NEVADA,
         CLEC will first determine whether the trouble is in CLEC's own
         equipment and/or facilities or those of the End User. If CLEC
         determines the trouble is in NEVADA's equipment and/or facilities, CLEC
         will issue a trouble report to NEVADA.

12.5.3   CLEC will pay Additional Labor charges when CLEC reports a suspected
         failure of a network element and NEVADA dispatches personnel to the End
         User's premises or a NEVADA central office and trouble was not caused
         by NEVADA's facilities or equipment. Additional Labor charges will
         include all technicians dispatched, including technicians dispatched to
         other locations for purposes of testing. Rates for Additional Labor
         will be billed pursuant to NEVADA's tariff P.S.C.N. C, Section 13.

12-5.4 CLEC shall pay Additional Labor charges when NEVADA dispatches personnel
     and the trouble is in equipment or communications systems provided by an
     entity other than NEVADA or in detariffed CPE provided by NEVADA.

12.5.5   If CLEC issues a trouble report allowing NEVADA access to the End
         User's premises and NEVADA personnel are dispatched but denied access
         to the premises, then Additional Labor charges will apply for the
         period of time that NEVADA personnel are dispatched.

12.5.6   Additional Labor charges apply on a first and additional basis for each
         half hour or fraction thereof. If more than one technician is
         dispatched in conjunction with the same trouble report, the total time
         for all technicians dispatched will be aggregated prior to the
         distribution of time between the "First Half Hour or Fraction Thereof'
         and "Each Additional Half Hour or Fraction Thereof' rate categories.
         Basic Time is work related efforts of NEVADA performed during normally
         scheduled working hours on a normally scheduled work day. Overtime is
         work related efforts of NEVADA performed on a normally scheduled work
         day, but outside of normally scheduled working hours. Premium Time is
         work related efforts of NEVADA performed other than on a normally
         scheduled work day.

12-5.7   If CLEC requests or approves a NEVADA technician to perform services in
         excess of or not otherwise contemplated by the nonrecurring charges
         herein, CLEC will pay for any additional work to perform such services,
         including requests for installation or conversion outside of normally
         scheduled working hours.

          12.6 Other Pricing Terms and Conditions for Unbundled Local Switching
          ("ULS")

 1-2.6.1 When CLEC purchases unbundled Local Switching, CLEC may also order
         available NEVADA vertical features that the switch is equipped to
         provide. CLEC will pay the monthly and nonrecurring charges for such
         features as listed in Appendix PRICING.

 12-6.2  Use of NEVADA's SS7 signaling network will be provided for unbundled
         local switching. CLEC does not separately order SS7 under this method.

 12.6.3  With unbundled Local Switching, NEVADA will make available features
         that require resources outside the switch, but CLEC will pay additional
         charges (e.g., TCAP messages, SS7 Signaling, database queries, etc.)
         for such features.

         Southwestern Bell Company family of companies, or any person to use the
         subscriber listing information for any other purpose. NEVADA shall take
         appropriate measures to guard against any unauthorized use of the
         listings provided to it hereunder (at least the same measures NEVADA
         takes to protect its own listings from unauthorized use), whether by
         NEVADA, its agents, employees or others.

5.       LIABILITY

5.1  CLEC hereby releases NEVADA from any and all liability for damages due to

         errors or omissions in CLEC's subscriber listing information as
         provided to NEVADA under this appendix, and/or CLEC's subscriber
         listing information as it appears in the White Pages directory,
         including, but not limited to, special, indirect, consequential,
         punitive or incidental damages.

 5.2     CLEC shall indemnify, protect, save harmless and defend NEVADA (or
         NEVADA's officers, employees, agents, assigns and representatives) from
         and against any and all losses, liability, damages and expense arising
         out of any demand, claim, suit or judgment by a third party in any way
         related to any error or omission in CLEC's subscriber listing
         information as it appears in the White Pages directory, including any
         error or omission related to non-published or nonlisted subscriber
         listing information. CLEC shall so indemnify regardless of whether the
         demand, claim or suit by the third party is brought jointly against
         CLEC and NEVADA, and/or against NEVADA alone. However, if such demand,
         claim or suit specifically alleges that an error or omission appears in
         CLEC's subscribers listing information in the White Pages directory,
         NEVADA may, at its option, assume and undertake its own defense, or
         assist in the defense of CLEC, in which event CLEC shall reimburse

                      ACCESS TO THE TOLL FREE CALLING DATABASE

This Appendix sets forth the terms and conditions under which NEVADA provides
Access to the Toll Free Calling Database.

1.       DESCRIPTION

         1.1      NEVADA's 800 database, an ANSI SS7 call-related database
                  system, receives updates processed from the national System
                  Management System/800 ("SMS/800") database. Customer records
                  in the SMS/800 are created or modified by entities known as
                  Responsible Organizations ("RespOrd") who obtain access to the
                  SMS/800 via the System Management System/800 database, Tariff
                  FCC No. 1. 800 Service Providers must either become their own
                  RespOrg or use the services of an established RespOrg. The
                  services of a RespOrg include creating and updating 800
                  records in the SMS/800 to download to the 800 database(s).
                  NEVADA does not, either through a tariff or contract, provide
                  RespOrg service.

          1.2 After the 800 customer record is created in the SMS/800, the
          SMS/800 downloads

                  the records to the appropriate databases, depending on the
                  area of service chosen by the 800 subscriber. An 800 customer
                  record is created in the SMS/800 for each 800 number to be
                  activated. The SMS/800 initiates all routing changes to update
                  information on a nationwide basis.

          1.3 Access to the Toll Free Calling Database allows CLEC to access
          NEVADA's 800

                  database for the purpose of switch query and database
                  response. Access to the Toll Free Calling Database supports
                  the processing of toll free calls (e.g., 800 and 888) where
                  identification of the appropriate carrier (800 Service
                  Provider) to transport the call is dependent upon the full ten
                  digits of the toll free number (e.g., 1+800+NXX+X)CXX). Access
                  to the Toll Free Calling Database includes all 800-type
                  dialing plans (i.e., 800, 888, and other codes as may be
                  designated in the future).

         1.4      Access to the Toll Free Calling Database provides the carrier
                  identification function required to determine the appropriate
                  routing of an 800 number based on the geographic origination
                  of the call, from a specific or any combination of NPA/NXX,
                  NPA or LATA call origination detail.

          1.5     There are three optional features available with 800 service:

                  (a)     POTS Translation;

                  (b)     Multiple Destination;. and

                                      351
<PAGE>

(c)     Six-Digit Master Number List Turnaround.

1.5.1    The POTS Translation feature converts the 800 number into a designated
         10-digit number. If the 800 Service Provider provides the designated
         10digit number associated with the 800 number and requests delivery of
         the designated 10-digit number in place of the 800 number, NEVADA will
         deliver the designated I 0-digit number.

1.5.2 The Multiple Destination feature allows the customer to create routing
schemes utilizing:

(a)      Time of Day;

(b)      Day of Week

(c)      Day of Year

(d)      Allocation of Traffic by Percentage

(e)      NPA-NXX-XXXX

                   1.5.3   The Six-Digit Master Number List Turnaround feature
                           applies when customer identification is performed for
                           Canadian and Caribbean toll free numbers. This
                           feature is billed in lieu of the Basic Toll Free
                           Access Query charge.

2.       TERMS AND CONDITIONS

2.1      Access to the Toll Free Calling Database provided under these terms and
         conditions is only available for use in the provision of telephone
         exchange and exchange access telecommunications services as specified
         in the Telecommunications Act of 1996 and any effective rules and
         regulations of the Federal Communications Commission and Public Utility
         Commission of Nevada.

2.2      Access to the Toll Free Calling Database is offered separate and apart
         from other unbundled network elements necessary for operation of the
         network routing function addressed in these terms and conditions, e.g.,
         end office 800 SSP functionality and CCS/SS7 signaling. This Appendix
         is separate from the prices, terms, conditions and billing for such
         related elements, and in no way shall this Appendix be construed to
         circumvent the prices, terms, conditions or billing as specified for
         such related elements.

2.3  CLEC shall address its queries to NEVADA's database to the alias point code
     of the ST? pair identified by NEVADA. CLECs queries shall use subsystem

                                      352
<PAGE>

number 0 in the calling party address field and a translations type of 254 with
a routing indicator set to route on global title. CLEC acknowledges that such
subsystem number and translation type values are necessary for NEVADA to
properly process queries to its 800 database.

2.4      Each Party warrants to the other that it shall send queries and SS7
         messages conforming to the ANSI approved standards for SS7 protocol and
         pursuant to the Specifications and Standards documents attached and
         incorporated herein in Exhibit I. Both Parties acknowledge that
         transmission in said protocol is necessary for each Party to provision
         Access to the Toll Free Calling Database (or the equivalent thereof).
         Each Party reserves the right to modify its network pursuant to other
         specifications and standards, which may include Bellcore Specifications
         defining specific service applications, message types, and formats,
         that may become necessary to meet the prevailing demands within the
         U.S. telecommunications industry. All such changes shall be announced
         in accordance with the then prevailing industry standard procedures.
         Each Party shall work cooperatively to coordinate any necessary
         changes.
2.5      CLEC acknowledges and agrees that CCS/SS7 network overload due to
         extraordinary volumes of queries and/or other SS7 network messages can
         and will have a detrimental effect on the performance of NEVADA's
         CCS/SS7 network and its 800 database. CLEC further agrees that NEVADA,
         at its sole discretion, may employ certain automatic and/or manual
         overload controls within NEVADA's CCS/SS7 network to guard against
         these detrimental effects. NEVADA shall report to CLEC any instances
         where overload controls are invoked due to CLECs CCS/SS7 network. CLEC
         shall take immediate corrective actions as are necessary to cure the
         conditions causing the overload situation.

2.6      During periods of 800 database system congestion, NEVADA shall utilize
         an automatic code gapping procedure to control congestion that may
         affect the service of all customers of NEVADA's 800 database. The
         automatic code gapping procedure used by NEVADA shall notify the CLEC's
         switch of the gap length (how long CLECs switch should wait before
         sending another query) and the gap duration (how long the switch should
         continue to perform gapping). For example, during an overload
         condition, the automatic code gapping procedures shall tell NEVADA 's
         800 database when to begin to drop one out of three queries received.
         This code gapping procedure shall be applied uniformly to all users of
         NEVADA's 800 database. NEVADA reserves the right to manually invoke the
         automatic code gapping procedure to control congestion.

2.7      Prior to NEVADA initiating service under this Appendix, CLEC shall
         provide an initial forecast of busy hour query volumes. CLEC shall
         update its busy hour forecast for each upcoming calendar year (January
         - December) by October I of the preceding year and also whenever CLEC
         anticipates a change to existing

                                      353
<PAGE>

forecasts. CLEC shall provide such updates each year for the first three (3)
years of this Appendix. If, prior to the establishment of a mutually agreeable
service effective date, in writing, NEVADA, at its discretion, determines that
it lacks adequate processing capability to provide Access to the Toll Free
Calling Database to CLEC, NEVADA shall notify CLEC of NEVADA's intent not to
provide the services under this Appendix and this Appendix will be void and have
no further effect.

2.8      CLEC shall from time to time at NEVADA's request, provide additional
         forecasted information as deemed necessary by NEVADA for network
         planning in connection with this offering.

2.9      NEVADA shall test the Access to the Toll Free Calling Database in
         conjunction with CCS/SS7 Interconnection Service (e.g., SS7 Appendix)
         as outlined in Bellcore Technical References TR-NWT-000533,
         GR-954-CORE, GR-905 CORE, and PUB L-780023-PB/NB.

2.10     CLEC shall only use Access to the Toll Free Calling Database to
         determine the routing requirements for originating 800 calls. Neither
         CLEC nor carrier customers of CLEC, if CLEC is acting on behalf of
         other carriers, shall use the database information to copy, store,
         maintain or create any table or database of any kind or for any
         purpose. If CLEC acts on behalf of other carriers to access NEVADA's
         Toll Free Calling Database, CLEC shall prohibit such carriers from
         copying, storing, maintaining, or creating any table or database of any
         kind from any response provided by NEVADA after a query to NEVADA's
         Toll Free Calling Database. CLEC shall only use this network element in
         connection with the provision of telephone exchange and exchange access
         services.

2.11     CLEC shall ensure that it has sufficient link capacity and related
         facilities to handle its signaling and toll free traffic without
         adversely affecting other network subscribers.

2.12     NEVADA shall provide Access to the Toll Free Calling Database as set
         forth in this Appendix only as such elements are used for CLEC's
         activities on behalf of its Nevada local service customers where NEVADA
         is the incumbent local exchange carrier. CLEC agrees that any other use
         of NEVADA's Toll Free Calling Database for the provision of 800
         database service by CLEC will be pursuant to the terms, conditions,
         rates, and charges of NEVADA's effective tariffs, as revised, for 800
         database services.

2.13 This Appendix shall become effective on date) and shall

         continue for one (1) year from the effective date of implementation of
         Access to the Toll Free Calling Database. Thereafter, this Appendix
         shall remain in effect unless terminated by either Party upon written
         notice given sixty (60) days in advance of the termination date.

                                      354
<PAGE>

         2.14     Ordering and billing inquiries for the elements described
                  herein shall be directed to the Local Service Center ("LSC").
                  Ordering' shall be done through the LSC using the standard
                  CLEC order form and NEVADA's CCS/SS7 Interconnect
                  Questionnaire, if applicable.

3.       RATE REGULATIONS

3.1      CLEC shall pay the rates for Access to the Toll Free Calling Database,
         as described in Appendix PRICING. These rates and charges will apply
         for one (1) year from the service effective date for each exchange.
         After one (1) year, NEVADA may change the rates upon sixty (60) days'
         notice. NEVADA may first give such notice sixty days before the end of
         the first year.
3.2      Rate Elements
