        NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                MARCH 31, 2000

1.  Basis of Presentation:

  These accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and notes required by generally accepted accounting principles for
complete financial statements. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, considered necessary for a fair
presentation for the periods indicated, have been included. Operating results
for the three month period ended March 31, 2000 are not necessarily indicative
of the results that may be expected for the year ending December 31, 2000. The
balance sheet at December 31, 1999 has been derived from the audited balance
sheet at that date, but does not include all of the information and notes
required by generally accepted accounting principles for complete financial
statements. These unaudited interim condensed consolidated financial statements
should be read in conjunction with the audited financial statements and the
notes thereto of Pac-West Telecomm, Inc. (the Company) as of and for the year
ended December 31, 1999.

  These consolidated financial statements include the results of operations of
Napa Valley Telecom (Napa Telecom) and Installnet, Inc. and two other related
companies (collectively referred to as Installnet) since their acquisitions in
January and February 2000, respectively (see Note 2).

2.  Organization:

  Pac-West Telecomm, Inc. is a rapidly-growing provider of integrated
communications services in the western United States. Our customers include
Internet service providers (ISPs), small and medium businesses and enhanced
communications service providers, many of which are communications intensive
users.

  In January 2000, the Company acquired the customer base and certain other
assets of Napa Telecom, a switched-based, long distance telecommunications
company headquartered in Napa Valley, California. In February 2000, the Company
acquired all of the outstanding stock of Installnet, which is headquartered in
Southern California. Installnet is primarily in the business of
telecommunications equipment installation. These acquisitions are being
accounted for using the purchase method of accounting.

  The total purchase price of Napa Telecom, which was paid in cash, was
approximately $4,400,000 plus additional payments not to exceed $500,000 if
certain revenue targets are met. In connection with this acquisition, the
Company granted certain key employees of Napa Telecom options to purchase the
Company's common stock at its November 1999 initial public offering price of
$10. As a result, the Company will recognize deferred compensation of
approximately $900,000, which will be amortized as an operating expense over the
four year vesting term of such options. For the three month period ended March
31, 2000, $66,000 of this amount was amortized.

  The total purchase price of Installnet, which was paid in a combination of
cash and stock, approximated $13,300,000 plus additional payments not to exceed
$1,500,000 if certain revenue targets are met. In addition, the Company has
granted options to certain Installnet employees to purchase an aggregate of
105,000 shares of the Company's common stock at the market price on the date of
grant.

  As of March 31, 2000, no revenue earnout milestones have been reached under
either of these agreements. Therefore, no accruals have been recorded for any of
these potential increases to the purchase prices.

3.   Revenue Recognition:

     Revenues from the sale of telecommunications products are recognized in the
month in which the service is provided, except for reciprocal compensation
generated by calls placed to ISPs connected through the Company's network. The
rights of Competitive Local Exchange Carriers (CLECs), such as the Company, to
receive this type of compensation is the subject of numerous regulatory and
legal challenges (see Note 16). Until this issue is ultimately resolved, the
Company will continue to recognize this revenue when received in cash or when
collectibility is reasonably assured.

     Revenues from the sale of telecommunications products are recognized upon
installation, or if no installation is required, upon shipment.


4.   Short-Term Investments:

     All investments with an original maturity of greater than three months from
the date of acquisition are accounted for under Financial Accounting Standards
Board (FASB) Statement No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." The Company determines the appropriate classification at the
time of purchase. All investments as of March 31, 2000 were classified as
available-for-sale and appropriately carried at fair value. Realized gains and
losses are included in other income, net in the accompanying statements of
operations. Differences between cost and fair value are recorded as unrealized
gains and losses in a separate component of stockholders' equity. At March 31,
2000, $219,000 was recorded as unrealized losses from investments.

5.  Equipment, Vehicles and Leasehold Improvements:

  Equipment, vehicles and leasehold improvements include network and other
communication equipment, office furniture and equipment, vehicles, leasehold
improvements, projects-in-progress and equipment deposits. These assets are

</TABLE>

     Deferred financing costs consist primarily of capitalized amounts for
underwriter fees, professional fees and other expenses related to the issuance
and subsequent registration of the $150,000,000 Senior Notes. These deferred
financing costs are being amortized on a straight-line basis (which approximates
the effective interest method) over the estimated 10-year term of the notes
beginning January 29, 1999. Amortization of deferred financing costs for the
three month periods ended March 31, 2000 and 1999 was $213,000 and $625,000,
respectively, and is included within interest expense in the accompanying
statements of operations.

     Acquisition of lease rights pertain to the purchase in 1999 of lease rights
for additional space in Los Angeles, and is being amortized over the life of the
lease.


8.   Other Accrued Liabilities:

     Other accrued liabilities at March 31, 2000 include $850,000 in acquisition
related hold-backs pertaining to the Napa Telecom acquisition, and $433,000 in
Installnet accrued accumulated warranty and maintenance on their equipment
sales.


9.   Income Taxes:

     The Company's effective income tax rate for the three month period ended
March 31, 2000 was 44%. Such rate reflects the applicable federal and state
statutory income tax rates along with the tax impact of the non-deductibility of
certain acquisition related amortization and deferred stock compensation. The
effective income tax rate for the three month period ended March 31, 1999 was
40%.


10.  Other Comprehensive Income:

     In September 1997, the FASB issued Statement of Financial Accounting
Standards (SFAS) No. 130, "Reporting Comprehensive Income". SFAS No. 130
establishes the disclosure requirements for comprehensive income and its
components within the financial statements. For the three month period ended
March 31, 2000, there was $219,000 of other comprehensive loss pertaining to the
net unrealized investment loss during the three months. There were no items of
other comprehensive income for the three month period ended March 31, 1999;
therefore, comprehensive income is the same as net income for that period.

<PAGE>

11.  Other Recent Pronouncements:

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and for Hedging Activities," effective for fiscal years beginning
after June 15, 1999. Management does not expect adoption of SFAS No. 133 to have
a significant impact on the Company's financial statements in future periods.

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 (SAB 101), "Revenue Recognition in Financial
Statements." SAB 101 provides guidance on applying generally accepted accounting
principles to revenue recognition in financial statements, and is effective for
the Company during the second quarter of 2000. We are currently evaluating the
impact of SAB 101 on our revenue recognition policies.

     In March 2000, the FASB issued Financial Accounting Standards Board
Interpretation No. 44 (Interpretation No. 44), "Accounting for Certain
Transactions involving Stock Compensation - an Interpretation of APB No. 25".
Interpretation No. 44 is effective July 1, 2000. Interpretation No. 44 clarifies
the application of Accounting Principles Board Opinion No. 25 for certain
issues, specifically, (a) the definition of an employee, (b) the criteria for
determining whether a plan qualifies as a compensatory plan, (c) the accounting
consequence of various modifications to the terms of a previous fixed stock
option or award, and (d) the accounting for an exchange of stock compensation
awards in a business combination. We do not anticipate that the adoption of
Interpretation No. 44 will have a material impact on our financial position or
on the results of our operations.


12.  Long-Term Debt:

     Long-term debt at March 31, 2000 and December 31, 1999 consist of the

     The Company has a three-year senior credit facility expiring June 15, 2002
that provides for maximum borrowings of $40.0 million to finance working
capital, the costs in connection with the Company's planned capital expansion
and other corporate transactions. The borrowings are secured by substantially
all of the Company's assets. Borrowings under this senior credit facility bear
interest, at the Company's option, at (1) the Base Rate (as defined in our
senior credit facility) or (2) the LIBOR Rate (as defined in our senior credit
facility) plus between 2.25% and 3.5%. As of March 31, 2000, there were no
amounts outstanding under this facility and the borrowing rate would have been
8.38%.


13.  Purchase Commitments:

     At March 31, 2000, the Company has approximately $10,000,000 of purchase
orders outstanding for network equipment due for delivery during 2000. These
purchase orders are cancelable up to 60 days prior to delivery without penalty
and are expected to be financed from existing cash and investments, from
internally generated cash flows, or from borrowings under the senior credit
facility.

     In addition, the Company is in the process of implementing a new billing
and operations support system. Total estimated costs for this system aggregate
approximately $15,000,000, of which approximately $9,600,000 of the total cost
has been incurred through March 31, 2000, $3,900,000 and $1,500,000 of the total
cost is expected to be incurred during the balance of 2000 and 2001,
respectively. The $9,600,000 incurred to date is recorded in projects-in-
progress at March 31, 2000.

16.  Legal Proceedings:

     The Company has established interconnection agreements with certain
Incumbent Local Exchange Carriers (ILECs). The Telecommunications Act of 1996
requires ILECs to enter into interconnection agreements with CLECs, such as the
Company and other competitors, and requires state Public Utilities Commissions
(PUCs) to arbitrate such agreements.

     The interconnection agreements outline, among other items, compensation
arrangements for calls originating or terminating in the other party's switching
equipment, payment terms, and level of services.

     Various ILECs have disputed, and are continuing to dispute, that internet
traffic calls made to an ISP are not local calls, and as such are not covered by
the interconnection agreements.

     The Company is a party to various legal proceedings, including the Pacific
Bell and California Public Utilities Commission (CPUC) and the Nevada Bell and
Public Utilities Commission of Nevada proceedings, relating to reciprocal
compensation payment and other interconnection agreement issues.

     In addition, in February 1999 the Federal Communications Commission (FCC)
issued a Declaratory Ruling on the issue of reciprocal compensation for calls
bound to ISPs. The FCC ruled that the calls are jurisdictionally mixed, but
largely interstate calls. The FCC, however, determined that this issue did not
resolve the question of whether reciprocal compensation is owed. The FCC noted a
number of factors that would allow the state PUCs to leave their decisions
requiring the payment of compensation undisturbed. On March 17, 2000, the U.S.
Courts of Appeals for the District of Columbia vacated the FCC's declaratory
ruling and remanded the matter to the FCC. The court determined that the FCC has
not provided a reasonable basis for treating calls to ISP's differently from
other local calls, and therefore reciprocal compensation should apply.

     Further, in February 2000 the CPUC commenced a separate generic proceeding
to develop its policy regarding reciprocal compensation.

     We cannot predict the impact of the FCC's ruling on existing state
decisions or the outcome of pending appeals or on additional cases in this
matter. Given the uncertainty concerning the final outcome of the PUCs
proceedings, the possibility of future extended appeals or additional
litigation, and future decisions by the FCC, we continue to recognize the
revenue associated with reciprocal compensation billings to ILECs when received
in cash or when collectibility is reasonably assured.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS


     Except for the historical information contained herein, this report
contains forward-looking statements, subject to uncertainties and risks, and as
a result, our actual results may differ materially from those discussed here.
These uncertainties and risks include among others, the successful execution of
our expansion activities into new geographic markets on a timely and cost-
effective basis; the pace at which new competitors enter our existing and
planned markets; competitive responses of the Incumbent Local Exchange Carriers
(ILECs); execution of interconnection agreements with ILEC's on terms
satisfactory to us; maintenance of our supply agreements for transmission
facilities; continued acceptance of our services by new and existing customers;
the outcome of legal and regulatory proceedings regarding reciprocal
compensation for Internet-related calls and certain of our product offerings;
the ability to attract and retain talented employees; and our ability to
successfully access markets, install switching electronics, and obtain the use
of leased fiber transport facilities and any required governmental
authorizations, franchises and permits, all in a timely manner, at reasonable
costs and on satisfactory term and conditions, as well as regulatory,
legislative and judicial developments that could cause actual results to differ
materially from the future results indicated, expressed, or implied, in such
forward-looking statements. These and other factors are discussed in our
Prospectus dated November 3, 1999, and in our annual report as of December 31,
1999, on Form 10-K as filed with the Securities and Exchange Commission (SEC).



Overview

     Pac-West Telecomm, Inc. is a rapidly-growing provider of integrated
communications services in the western United States. Our customers include
Internet service providers (ISPs), small and medium businesses and enhanced
communications service providers, many of which are communications intensive
users. Our predecessor, also known as Pac-West Telecomm, Inc., began selling
office phone systems in 1980 and reselling long distance service to small and
medium businesses and residential customers in 1982. Beginning in 1986, our
predecessor began offering paging and telephone answering services to its
customers. Effective September 30, 1996, our predecessor transferred its
telephone and answering service divisions to us. Prior to September 30, 1996, we
did not conduct any operations and, since that time, we have disposed of the
answering service division and have focused our business strategy on operating
as a provider of integrated communications services.

     For the three month periods ended March 31, 2000 and March 31, 1999,
recognizing compensation from other communications companies for completing
their customers' calls only to the extent such compensation was actually
received in cash or when collectibility was reasonably assured, we had net
revenues of approximately $30.8 million and $14.4 million, respectively, and
EBITDA of approximately $10.6 million and $6.1 million, respectively.

     As of March 31, 2000, we had 124,340 lines in service, an 84% increase from
March 31, 1999. For the quarter ended March 31, 2000 our minutes of use were 5.4
billion, an increase of 74% over the first quarter of 1999.


Factors Affecting Operations:

     Revenues. We derive our revenues from monthly recurring charges, usage
charges and initial non-recurring charges and telephone equipment sales and
service. Monthly recurring charges include the fees paid by customers for lines
in service and additional features on those lines, as well as equipment
collocation services. Usage charges consist of fees paid by end users for each
call made, fees paid by ILECs as reciprocal compensation for completion of their
customers' calls through Pac-West, and access charges paid by carriers


                                      11

<PAGE>

for long distance traffic terminated by Pac-West. Initial non-recurring charges
are paid by end users, if applicable, for the installation of our service.

     We derive a substantial portion of our revenues from reciprocal
compensation paid by ILECs with which we have interconnection agreements.
Reciprocal compensation revenue increased in recent fiscal quarters as a result
of increasing inbound call volume from our ISP and other customers in addition
to the effect of certain ILEC's discontinuing the withholding of certain
reciprocal compensation payments. Such increases in revenues, however, were
offset by lower contractual rates for reciprocal compensation. For the three
month periods ended March 31, 2000 and March 31, 1999, recorded reciprocal
compensation accounted for 46.3 % and 42.1%, respectively, of our revenues.

     As recently as fiscal year 1999, two ILECs with which we have
interconnection agreements, Pacific Bell and GTE, refused to pay that portion of
reciprocal compensation due under their interconnection agreements that they
estimated was the results of inbound calls terminating to ISPs. These ILECs
contended that such ISP calls are not local calls within the meaning of their
respective interconnection agreements and claimed that no reciprocal
compensation was therefore payable. While these ILECs have been paying us the
full amount of our reciprocal compensation billings since the latter half of
1999, some of these payments may be subject to a reservation of rights to
appeal, contest or seek subsequent reimbursement of amounts previously paid by
them for reciprocal compensation.

     We expect that reciprocal compensation will continue to represent a
significant portion of our revenues in the future. We are currently negotiating
and implementing new interconnection agreements and the terms of the related
reciprocal compensation. The per minute reciprocal compensation rate we receive
from Pacific Bell under our 1999 renewal agreement is significantly lower than
it was under our previous agreement. Based on current market conditions, we also
expect that the per minute reciprocal compensation rate will decline from
historic rates under other future interconnection agreements.

     Operating Costs. Operating costs are comprised primarily of leased
transport charges, usage charges for long distance and intrastate calls and, to
a lesser extent, reciprocal compensation related to calls that originate with a
Pac-West customer and terminate on the network of an ILEC or other Competitive
Local Exchange Carrier (CLEC). Our leased transport charges are the lease
payments we incur for the transmission facilities used to connect our customers
to our switches and to connect to the ILEC and other CLEC networks. Our strategy
of leasing rather than building our own transport facilities results in our
operating costs being a significant component of total costs and expenses.

     Selling, General and Administrative Expenses. Our selling, general and
administrative expenses include network operation, development, administration
and maintenance costs, selling and marketing, customer service, information
technology, billing, corporate administration and personnel. We expect to incur
significant selling and marketing costs as we continue to expand our operations,
a significant amount of which will be incurred in a particular market before the
switch becomes operational and begins to generate revenue. Consequently, selling
and marketing expenses are expected to increase until implementation of our
expansion plan is substantially complete. We will incur other costs and
expenses, including the costs associated with the development and maintenance of
our networks, administrative overhead, premises leases and bad debts. We expect
that these costs will grow significantly as we expand our operations and that
sales and marketing and administrative overhead will be a large portion of these
expenses during the start-up phase in each of our new markets.

Three Month Period Ended March 31, 2000 Compared to Three Month Period Ended
March 31, 1999:

     Consolidated revenues for the three month period ended March 31, 1999
increased $16.4 million to $30.8 million from $14.4 million for the
corresponding period in 1999. The increase in revenues was primarily attributed
to an increase of $8.2 million in paid local interconnection revenues, an
increase of $1.3 million in recurring charges and installation charges billed
directly to ISPs, an increase of $2.0 million in local and long distance usage
revenues, of which $1.4 million was attributed to customers acquired in
connection with our acquisition of Napa Telecom in January 2000, and $1.6
million in product and service revenues for the two months of consolidation of
Installnet, which we acquired in February 2000.

     In the first half of 1999, we activated a new higher capacity switch in
Oakland, continued to expand our switching capacity in Los Angeles and finished
construction of a switching facility in Las Vegas. During the fourth quarter of
1999, we installed a second switching system at our Los Angeles facility and
constructed a switching facility in Seattle. Our revenues for the three month
period ended March 31, 2000 also increased from the three month period ended
March 31, 1999 as a result of additional switch capacities, and increased
utilization of our expanded switch capacities, primarily attributable to ISP
customers. In addition, new service orders from small and medium businesses have
continued to accelerate in 2000 as we have built our sales force, with a 200%
increase in lines sold to small and medium business from March 31, 1999 to March
31, 2000.

     The number of access lines in service increased 84% to 124,340 as of March
31, 2000 from 67,691 as of March 31, 1999. Billable minutes of use were 5.4
billion in the first three months of 2000, up 74% from 3.1 billion for the first
three months of 1999.

     The number of inbound local calls and the minutes subject to reciprocal
compensation revenues in accordance with interconnection agreements increased
44% and 73% for the first three months of 2000 over the first three months of
1999, respectively. The effect of these significant increases in inbound local
calls and minutes, combined with Pacific Bell and GTE no longer withholding
payment on a portion of our billings, and offset by lower contractual rates with
Pacific Bell, resulted in an $8.2 million or 135% increase in paid
interconnection revenues for the period ended March 31, 2000 over the
corresponding period in 1999.

     The $1.3 million increase in the first three months of 2000 over the first
three months of 1999 in direct billings to ISPs represented a 32% year to year
increase. Lines used by our ISPs increased in the first three months of 2000
over the corresponding period in 1999, to 89,436 lines in service by ISPs at
March 31, 2000, from 56,320 lines in service at March 31, 1999.

     Lines in service to our small and medium business customers also increased
significantly to 21,300 lines in service at March 31, 2000 from 7,458 lines in
service at March 31, 1999, which is an increase of 186%.

     The $2.0 million increase in outbound local and long distance revenues,
including 800, 888, and 877 numbers and travel card calls, represented a 104%
increase for the three months ended March 31, 2000 over the corresponding period
in 1999. Internal growth and the acquisition of Napa Valley Telecom customers
accounted for a 36% and 68% increase, respectively, in outbound local and long
distance revenues. These increases are directly related to our focus on
providing services to high-volume, telecommunication intensive users and small
and medium businesses.

     Our consolidated operating costs for the three month period ended March 31,
2000 increased $5.9 million, to $10.0 million from $4.1 million for the
corresponding period in 1999. The increase in operating costs was primarily due
to an increase in network operations associated with a higher level of
telecommunications activity. In addition, we made significant investments in our
telephone infrastructure during the last nine months of 1999 and the first three
months of 2000 to accommodate future growth of our communications services. Of
the $10.0 million in operating costs for the three month period ended March 31,
2000, $1.3 million was attributable to Installnet and $1.0 million was
attributable to Napa Telecom. Excluding revenues and operating expenses
attributable to these acquisitions, operating costs were 28.0% of revenues
compared to 28.2% for the corresponding 1999 three months.

     Our consolidated selling, general and administrative expenses for the three
month period ended March 31, 2000 increased $5.9 million to $10.2 million from
$4.3 million for the corresponding period in 1999. The increase in selling,
general and administrative expenses was primarily due to the addition of 68
employees in Pac-West's sales and marketing departments; an increase in network
operational, development and administration costs, including 30 additional
network employees; an increase of 25 service technicians and 39 customer service
representatives; and 43 additional employees in other administration and
information technology functions. The total number of Pac-West employees
increased from 167 at March 31, 1999 to 372 at March 31, 2000. In addition,
Installnet accounted for $0.9 million of the increase in selling, general and
administrative expenses and added an additional 110 employees to bring our
combined employee count to 482 at March 31, 2000. Excluding revenues and
selling, general and administrative expenses for the acquisitions, our selling,
general and administrative expenses were 31.9% of revenues for the three months
in 2000 as compared to 29.8% for the corresponding period in 1999.

     Our consolidated depreciation and amortization expense for the three month
period ended March 31, 2000 increased $2.7 million to $4.1 million from $1.4
million for the corresponding period in 1999. The increase in depreciation and
amortization expense was primarily due to the additional depreciation on the
$56.4 million of equipment acquired during 1999.

     Our consolidated interest expense for the three month period ended March
31, 2000 increased $0.6 million to $4.6 million from $4.0 million in the
corresponding period in 1999. The increase in interest expense was primarily due
to three months of interest expense in the three months ended March 31, 2000 on
the $150 million senior notes issued on January 29, 1999, compared to two months
of interest expense during the corresponding period in 1999. Interest expense is
net of amounts capitalized of $0.7 million and $0.6 million for the three months
ended March 31, 2000 and 1999, respectively.

     The Company's effective income tax rate for the three month period ended
March 31, 2000 was 44%. Such rate reflects the applicable federal and state
statutory income tax rates along with the tax impact of the non-deductibility of
certain acquisition-related amortization and deferred stock compensation
expense. The effective income tax rate for the three month period ended March
31, 1999 was 40%.


Liquidity and Capital Resources:

     Net cash provided (used) by operating activities was $(3.0) million for the
three month period ended March 31, 2000 compared to $4.5 million for the
corresponding period in 1999. This decrease is primarily attributable to a $10.1
million semi-annual interest payment on the senior notes in the first quarter of
2000, increases in accounts receivable of $1.6 million and inventories of $1.7
million, offset by an increase in income from operations of $1.9 million and an
increase in interest income of $1.8 million in the first quarter of 2000 over
the corresponding period in1999.

     Net cash used in investing activities was $12.9 million for the three month
period ended March 31, 2000 compared to $23.3 million for the corresponding
period in 1999. During the three month period ended March 31, 2000, the Company
invested $11.6 million in new switching and related equipment as compared to
$3.6 million during the corresponding period in 1999. In 1999, $19.7 million of
the proceeds from the senior note offering were used to purchase short-term
investments to fund the interest reserve trust account for the first two
scheduled interest payments on the notes, and in 2000 the remaining $10.2
million was redeemed to pay the second scheduled interest payment. Also, in
2000, $9.4 million was paid to acquire Napa Telecom and Installnet.

     Net cash provided by financing activities was $3,000 for the three month
period ended March 31, 2000 compared to $44.9 million for the corresponding
period in 1999. The net cash provided in the three month period ended March 31,
1999 was primarily attributable to proceeds from the issuance of $150 million of
our senior notes reduced by the payoff of $100 million of senior secured
borrowings.

     The local telecommunications services business is capital intensive. Our
operations have required and will continue to require substantial capital
investment for the design, acquisition, construction and implementation of our
network. Capital expenditures were $11.6 million for the first three months of
2000, and $56.4 million for the year ended December 31, 1999. Of the capital
expenditures during 1999 and the first quarter of 2000, $28.2 million was
included in projects-in-progress at March 31, 2000 and therefore is not being
depreciated until placed in service in 2000. We are budgeted to make additional
capital expenditures of approximately $100 million during the balance of 2000,
excluding acquisitions. The actual cost of our planned expansion will depend on
a variety of factors, including the cost of the development of our network in
each of our new markets, the extent of competition and pricing of the
telecommunications services in such markets and the acceptance of our services.
Accordingly, our actual capital requirements may exceed the amounts described
above.

     Our senior credit facility provides for maximum borrowings of $ 40.0
million for working capital and other general corporate purposes, and bears
interest, at our option, at: (1) the Base Rate, as defined in our senior credit
facility; or (2) the LIBOR rate, as defined in our senior credit facility plus
between 2.25% and 3.5%.

     As of March 31, 2000, there were no amounts outstanding under this facility
and the borrowing rate would have been approximately 8.38%. Our borrowings under
our senior credit facility will be secured by all of our assets. Our senior
credit facility has a three year term expiring June 2002.

     Our principal sources of funds for the balance of 2000 are anticipated to
be current cash and investment balances, cash flows from operating activities,
and if necessary, borrowings under the senior credit facility. We believe that
these funds will provide us with sufficient liquidity and capital resources for
us to fund our business plan for the balance of 2000. No assurance can be given,
however, that this will be the case. The foregoing statements do not take into
account additional acquisitions which, if made, are expected to be funded
through a combination of cash and equity. Depending upon our rate of growth and
profitability, especially if we pursue any significant acquisitions, we may
require additional equity or debt financing to meet our working capital
requirements or capital equipment needs. There can be no assurance that
additional financing will be available when required or, if available, will be
on terms satisfactory to us.

     Instruments governing our indebtedness, including the senior credit
facility and the senior notes indenture, contain financial and other covenants
that restrict, among other things, our ability to incur additional indebtedness,
incur liens, pay dividends or make certain other restricted payments, consummate
certain asset sales, enter into certain transactions with affiliates, merge or
consolidate with any other person or sell, assign, transfer, lease, convey or
otherwise dispose of substantially all of our assets. Such limitations, could
limit corporate and operating activities, including our ability to respond to
market conditions to provide for unanticipated capital investments or to take
advantage of business opportunities.


Year 2000 Issues:

     During 1999, management completed the process of preparing for the Year
2000 date changes. This process involved identifying and remediating date
recognition problems in computer systems, software and other operating
equipment, working with third parties to address their Year 2000 issues, and
developing contingency plans to address potential risks in the event of Year
2000 failures. To date, we have successfully managed the transition. Although
considered unlikely, unanticipated problems in our core business processes,
including problems associated with non-compliant third parties and disruptions
to the economy in general could still occur despite efforts to date to remediate
affected systems and develop contingency plans. Management will continue to
monitor all business processes, including interaction with our customers,
vendors and other third parties, throughout 2000 to address any issues and
ensure all processes continue to function properly.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

     The SEC's rule related to market risk disclosure requires that we describe
and quantify our potential losses from market risk sensitive instruments
attributable to reasonably possible market changes. Market risk sensitive
instruments include all financial or commodity instruments and other financial
instruments that are sensitive to future changes in interest rates, currency
exchange rates, commodity prices or other market factors. We are not exposed to
market risks from changes in foreign currency exchange rates or commodity
prices. We do not hold derivative financial instruments nor do we hold
securities for trading or speculative purposes. At March 31, 2000 we had $150
million of fixed rate notes outstanding, and consequently we currently have no
risk exposure associated with increasing interest rates on our debt. In
addition, we have a line of credit which may, at our option, have a variable
interest rate tied to LIBOR; however there were no amounts outstanding at March
31, 2000. We are however exposed to changes in interest rates on our investments
in cash equivalents and short-term investments. Substantially all of our
investments in cash equivalents and short-term investments are in money market
funds that hold short-term investment grade commercial paper, treasury bills or
other U.S. government obligations. Currently this reduces our exposure to long-
term interest rate changes. We do not use interest rate derivative instruments
to manage our exposure to interest rate changes. A hypothetical 100 basis point
decline in short-term interest rates would reduce the annualized earnings on our
$139.0 million of cash equivalent and short-term investment at March 31, 2000 by
approximately $1,390,000.

ITEM 1. Legal Proceedings

        See Note 16 to the Unaudited Condensed Consolidated Financial Statements
included elsewhere in this Form 10-Q and "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Factors Affecting Operations--
Revenues" for a description of certain legal proceedings involving the Company.

ITEM 2. Changes in Securities and Use of Proceeds

        In February 2000, the Company acquired all of the outstanding equity of
Installnet in exchange for a combination of cash and common stock for an
aggregate purchase price of approximately $13,300,000. The terms of the
acquisition provide that the common stock component of the total purchase price
may vary between a minimum of approximately 295,730 shares of common stock and a
maximum of 443,593 shares of common stock based on the market price of the
Company's common stock six months from the date of the acquisition. In
connection with this arrangement, 443,593 shares of common stock were issued and
are currently outstanding, with 283,899 shares of common stock issued to the
former owners of Installnet and 159,694 shares of common stock issued into
escrow. The issuance of these securities was intended to be exempt from the
registration requirements of the Securities Act of 1933, as amended, by virtue
of Section 4(2) or Regulation D thereunder.

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.

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.

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.

         5.3.4 Local Traffic Interconnection Rates

                    Serving Method           Rates

                    Tandem Served            See Appendix PRICING
                    End Office Served        See Appendix PRICING

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.

         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
         terminate. this Agreement ninety (90) days after delivering written
         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

         25.1     The Parties negotiated the services, arrangements,
                  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.

                  each Party shall be responsible only for service(s) and
                  facility(ies) which are provided by that Party, its authorized
                  agents, subcontractors, or others retained by such parties,
                  and neither Party shall bear any responsibility for the
                  service(s) and facility(ies) provided by the other Party, its
                  agents, subcontractors, or others retained by such parties.

         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.

         27.3     In the case of any loss alleged or made by an End User of
                  either Party, the Party whose End User alleged or made such
                  loss ("Indemnifying Party") shall defend and indemnify the
                  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
                  Pacific Bell from any loss arising out of NEVADA's or Pacific
                  Bell's provision of 911 services or out of CLECs End Users'
                  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
                  make any warranty with respect to unbundled elements when used
                  in an explosive atmosphere.

         27.6     Each Party shall be indemnified, defended and held harmless by
                  the other Party against any loss arising from a Party's use of
                  services or elements provided under this Agreement involving:
<PAGE>

(a)      tort claims, including claims for libel;

(b)      slander;

(c)      invasion of privacy; or

(d)      infringement of copyright arising from a Party's own communications or

         the communications of its End Users.

This includes, but is not limited to, suits arising from disclosure of any
customerspecific information associated with either the originating or
terminating numbers used to provision unbundled elements provided hereunder or
all other claims arising out of any act or omission of the End User in the
course of using services or functions provided pursuant to this Agreement.

 27.7    The Indemnifying Party agrees to defend any suit brought against the
         Indemnified Party for any loss identified in this Section or specific
         appendices. The Indemnified Party agrees to notify the Indemnifying
         Party promptly in writing of any written claims, lawsuits or demands
         for which the Indemnifying Party may be responsible under this
         Agreement. The Indemnified Party shall cooperate in every reasonable
         way to facilitate defense or settlement. The Indemnifying Party -shall
         have the right to control and conduct the defense and settlement of any
         action or claim subject to the consultation of the Indemnified Party.
         The Indemnifying Party shall not be responsible for any settlement
         unless the Indemnifying Party approved such settlement in advance and
         agrees to be bound by the settlement agreement.

 27.8    CLEC acknowledges that its right under this contract to interconnect
         with NEVADA's network and to unbundle and/or combine NEVADA's network
         elements (including combining with CLEC's network elements) may be
         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
         event shall NEVADA be liable for any consequential damages or loss of
         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.

28.      LIMITATION OF LIABILITY

 28.1    Except for indemnity obligations under this Agreement, or except as
         otherwise provided in specific appendices, each Party's liability to
         the other Party for any loss relating to or arising out of any
         negligent act or omission in its performance under this Agreement,
         whether in contract or tort, shall not exceed in total the amount
         NEVADA or CLEC has to or would have charged the other Party for the
         affected service(s) or function(s) which were not performed or were
         otherwise improperly performed.

 28.2    Except for losses alleged or made by an End User of either Party, or
         except as otherwise provided in specific appendices, in the case of any
         loss alleged or made by a third party arising under the negligence or
         willful misconduct of both Parties, each Party shall bear, and its
         obligation under this section shall be limited to, that portion (as
         mutually agreed to by the Parties) of the resulting expense caused by
<PAGE>

its own negligence or willful misconduct or that of its agents, servants,
contractors, or others acting in aid or concert with it.

         28.3     In-no event shall either Party have any liability whatsoever
                  to the other Party for any indirect, special, consequential,
                  incidental, or punitive damages, including but not limited to,
                  loss of anticipated profits or revenue or other economic loss
                  in connection with or arising from anything said, omitted, or
                  done hereunder (collectively, "Consequential Damages"), even
                  if the other Party has been advised of the possibility of such
                  damages; provided that the foregoing shall not limit a Party's

               30.8.1 Each Party purchasing services hereunder shall pay or
                    otherwise be responsible for all federal, state, or local
                    sales, use, excise, gross receipts, transaction or similar

                    with respect to the services provided by or to such Party,
                    except for any Tax on either Party's corporate existence,
                    status, or income. Whenever possible, these amounts shall be
                    billed as a separate item on the invoice. To the extent a
                    sale is claimed to be for resale tax exemption, 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

                  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

          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

         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

         binding upon and shall inure to the benefit of the Parties' respective
         successors and assigns.

         Failure of either Party to insist on performance of any term or
         condition of this Agreement or to exercise any right or privilege

            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

            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

            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.

            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

            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.

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

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

   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.

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

         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.

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.

7.       MONTHLY BILLING

         NEVADA will render monthly billing statements to CLEC, and remittance
         in full will be due within thirty (30) days of receipt.

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
         to be caused, directly, or indirectly, by CLEC employees and equipment
         associated with provision of the DA Services. This provision includes
         but is not limited to suits arising from disclosure of the telephone
         number, address, or name associated with the telephone called or the
         telephone used to call the DA Services.

9.       TERMS OF APPENDIX

9.1      This Appendix will continue in force for the length of this Agreement,
         but no less than 12 months. Thereafter, either Party may terminate this
         agreement upon 90 day written notice to the other Party.

9.2      If CLEC terminates this agreement prior to the agreed-upon term of this
         Appendix, CLEC shall pay NEVADA, within thirty (30) days of the
         issuance of a final bill by NEVADA, all amounts due for actual services
         provided under this Appendix, plus estimated monthly charges for the
         remainder of the term. Estimated charges will be based on an average of
         the actual monthly amounts billed by NEVADA pursuant to this Appendix
         prior to its termination.

         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

         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,

                  demands, suits or other actions involving an allegation of the
                  infringement or invasion of the right of privacy or
                  confidentiality of any person or persons, caused or claimed to
                  have caused, directly or indirectly, by the installation,
                  operation, failure to operate, maintenance, removal, presence,
                  condition, occasion or use of the E911 Service features and
                  the equipment associated therewith, including by not limited
                  to the identification of the telephone number, address or name
                  associated with the telephone used by the party or parties
                  accessing E911 Service hereunder, except which arise out of
                  the negligence or other wrongful act of NEVADA or PACIFIC.

7.       MUTUALITY

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.

                  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.

          2.2.1.4 NEVADA does not offer PNP services and facilities for NXX
          codes 555, and 950.

2.2.2 Obligations Of NEVADA

          2.2.2.1 NEVADA will deploy LRN in the followin MSAs per the timelines
          set forth by the FCC, unless such timelines are extended by the FCC:

MSA                          DEPLOYNENT COMPLETED BY

Las Vegas                                June 30, 1998 *

         2.2.2.2     After December 31, 1998, NEVADA will deploy LRN in other
                     MSAs within six (6) months after receipt of a Bona Fide
                     Request (see ATTACHMENT 1) from CLEC.

2.2.3 Obligations of CLEC

          2.2.3.1 When purchasing the SPNP Database Query, CLEC will access
          NEVADA's facilities via an SS7 link (Section 6 of FCC No. 1 Access
          Service Tariff) to NEVADA's STP.

          2.2.3.2 When purchasing the SPNP Query - Prearranged, CLEC will advise
          NEVADA of the entry point(s) of queries to NEVADA's network and
          provide a query forecast for each entry point.

* If one or more switches are selected to become PNP capable
<PAGE>

          2.2.3.3 CLEC is responsible for advising the Number Portability
          Administration Center ("NPAC"), of telephone numbers that they import,
          and the associated data as identified in industry forums as being
          required for PNP.

          2.2.3.4 After the initial deployment of PNP in an MSA, CLEC shall
          submit a Bona Fide Request (see ATTACHMENT 1) to request that a NEVADA
          switch become LRN capable. The requested switch will be made LRN
          capable within the time frame stipulated by the FCC.

          2.2.3.5 When CLEC requests that an NXX in an LRN-capabl NEVADA switch
          become portable, CLEC shall follow the industry standard LERG
          procedures.

          2.2.3.6 CLEC shall be certified by the Regional NPAC prior to
          scheduling Intercompany testing of PNP.

          2.2.3.7 CLEC shall adhere to NEVADA's Local Service Request ("LSR")
          format and PNP due date intervals.

          2.2.3.8 CLEC shall adhere to NEVADA's reserved number terms and
          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
          provisioning and implementation processes.

          2.2.4.7 The Parties agree to implement PNP in compliance with the FCC
          or Commission orders, and pursuant to PUBL-780050-PB/NB, Pacific
          Bell/Nevada Bell Number Portability Network Interface Specification.

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

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

                  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

                  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:

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
         to the TOPS Access and OS trunks; or

(c)      CLEC purchases facilities, OS trunks and TOPS Access from

         NEVADA.

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

          5.3.3 TOPS trunking requirements are described in Appendix ITR.

          5.4 Facilities necessary for the provision of Operator 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.

5.5      CLEC will furnish to NEVADA a completed Operator Services
         questionnaire, forty-five (45) days in advance of the date when the
         Operator Services are to be undertaken, unless otherwise agreed to by
         the Parties.
<PAGE>

          5.6 CLEC will provide NEVADA timely updates to the OS questionnaire
          when changes are necessary. CLEC will provide any necessary records
          and changes to records to NEVADA in writing or in any other mutually
          agreeable format.

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

6.       METHODS AND PRACTICES

         NEVADA will provide the Operator Services to CLEC's End Users in
         accordance with NEVADA's OS methods and practices in effect for NEVADA
         at the time the OS call is made, unless otherwise agreed in writing by
         both Parties.

7.       PRICING

Pricing for Operator Services shall be based on the rates specified in Exhibit
I, which is attached and made part of this Appendix, and Appendix PRICING. The
rates will apply from the service effective date through the term of this
agreement as specified in Section 10.1 below. At any time beyond the specified
or the term of this Appendix, NEVADA may change the prices for the provision of
OS upon one hundred-twenty (120) days' notice to CLEC.

8.       MONTHLY BILLING

         NEVADA will render monthly billing statements to CLEC, and remittance
         in full will be due within thirty (30) days of receipt.

9.       LIABILITY

In addition to the limitation of liability and indemnification provisions of the
Agreement, 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 to be
caused, directly, or indirectly, by NEVADA employees and equipment associated
with provision of the Operator Services. This provision includes but is not
limited to suits arising from disclosure of the telephone number, address, or
name associated with the telephone called or the telephone used to call the
Operator Services.

10.      TERM OF APPENDIX

          10.1 This Appendix will continue in force for the length of the
          Interconnection Agreement, but no less than 12 months. Thereafter,
          either Party may terminate this agreement upon 90 days written notice
          to the other Party.
<PAGE>

          10.2 If CLEC terminates this agreement prior to the first twelve (12)
          months, CLEC shall pay, within thirty (30) days of the issuance of a
          final bill by NEVADA, all amounts due for actual services provided
          under this Appendix, plus estimated monthly charges for the remainder
          of the term. Estimated charges will be based on an average of the
          actual monthly amounts billed by NEVADA pursuant to this Appendix
          prior to its termination.

     10.3 The rates applicable for determining the amount(s) under the terms
outlined in this Section are those specified in Exhibit I attached hereto and

<PAGE>

                           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."

2.       Pre-Order

          2.1 NEVADA will provide real time access to pre-order functions to
support CLEC ordering of Resale services and UNE. The Parties acknowledge that
ordering requirements necessitate the use of current, real time pre-order
information to accurately build service orders. The following lists represent
pre-order functions that are available to CLEC so that CLEC order requests may
be created to comply with NEVADA ordering requirements.

          2.2      Pre-ordering functions for Resale services include:

          2.2.1 features and services available at a valid service address (as
          applicable);

                  2.2.2 access to NEVADA retail or resold customer proprietary
network information (CPNI) and account information for pre-ordering will
include: billing name, service address, billing address, service and feature
subscription, directory listing information, long distance carrier identity, and
pending service order activity (CLEC agrees that CLEC's representatives will not
access the information specified in this subsection until after the customer
requests that his or her local exchange service provider be changed to CLEC and
customer authorization for release of CPNI has been obtained which complies with
conditions as described in section 1.4 of this Appendix.);

          2.2.3 a telephone number (if the customer does not have one assigned)
          with the customer on-line,

2.2.4 service availability dates to the customer;

                    representatives will not access the information specified in
                    this subsection until after the customer requests that his
                    or her local exchange service provider be changed to CLEC
                    and customer authorization for release of CPNI has been
                    obtained which complies with conditions as described in
                    section 1.4 of this Appendix.);

          2.3.3 telephone number assignment (if the customer does not have one
          assigned) with the customer on-line;

                  2.4.1.1 Service Order Retrieval and Distribution (SORD) will
be available for the pre-order function of viewing the CPNI, when SORD is used
to order NEVADA resale service.

2.4.2 Resale and UNE Pre-order System Availability:

               2.4.2.1 DataGate is a transaction-based data query system through
                    which NEVADA will provide CLEC access to pre-ordering
                    functions. This gateway shall be a Transmission Control
                    Protocol/Internet Protocol (TCP/IP) gateway and will allow
                    CLEC to access the pre-order functions for Resale services
                    and UNE by CLEC developing its own enduser interface. NEVADA
                    and CLEC agree to cooperate in developing and implementing
                    an
<PAGE>

electronic communication interface that will be consistent with industry
guidelines developed by the OBF and the TCIF, assuming they are different from
that which NEVADA is providing.

                   - 2.4.2.2 Verigate is an end-user interface developed by
NEVADA that provides access to the pre-ordering functions for Resale Services
and UNE. Verigate may be used in connection with electronic or manual ordering.
Verigate will be accessible via Toolbar.

     2.4.2.3 CLEO is a NEVADA system which is available to provide the CLEC with
pre- order functions for Resale Service and UNE, with the exception of viewing
CPNI. CLEO will be replaced by Verigate.

2.5      Other Pre-order Function Availability:

                  2.5.1 Where pre-ordering functions are not available
electronically CLEC will manually request this information from NEVADA'S LSC for
inclusion on the service order request.

3.       Ordering/Provisioning

         3.1 NEVADA provides real time access to ordering functions (as measured
from the time NEVADA receives accurate service requests from the interface) to
support CLEC provisioning of Resale services and UNE via one or more electronic
interfaces. To order Resale services and LNEs, CLEC will format the service
request to identify what features, services, or elements it wishes NEVADA to
provision in accordance with NEVADA ordering requirements. NEVADA will provide
CLEC access to one or more of the following systems or interfaces:

         3.2      Resale Services Order Request System Availability:

                  3.2.1 NEVADA Bell Service Manager (PBSM) is available for
ordering Centrex and ISDN Resale Services.

                  3.2.2 When available, Service Order Retrieval and Distribution
(SORD) system will support the ordering of all Resale Services.

     3.3 Resale and UNE Service Order Request Ordering System Availability:

                  3.3.1 NEVADA makes available to CLEC an Electronic Data
Interchange (EDI) interface for transmission of NEVADA ordering requirements via
formats provided on the Local Service Request (LSR) as defined by the Ordering
and Billing Forum (OBF) and via EDI mapping as defined by TCIF. In ordering and
provisioning Resale, CLEC and NEVADA will utilize industry guidelines developed
by OBF and TCIF EDI to transmit data based upon NEVADA'S Resale ordering
requirements. In ordering and provisioning UNE CLEC and NEVADA will utilize
industry guidelines developed by OBF and TCIF EDI to transmit data
<PAGE>

based upon NEVADAS UNE ordering requirements. In addition, Interim Number
Portability will be ordered consistent with the OBF LSR and EDI process. EDI
ordering functionality will be made available as negotiated in time frames
mutually acceptable to NEVADA and CLEC.

                  3.3.2 CESAR supports the ordering of unbundled dedicated
transport and local interconnection hunks. In ordering and provisioning
unbundled dedicated transport and local interconnection hunks, CLEC and NEVADA
will utilize industry guidelines developed by OBF based upon NEVADA ordering
requirements.

                  3.3.3 When available, LSR Exchange (LEX) is a graphical user
interface provided by NEVADA that will provide access to the ordering functions
for Resale Services and UNE.

         3.4 Provisioning for Resale services and UNE: NEVADA will provision
Resale Services and UNE as detailed in CLEC order requests. Access to status on
such orders will be provided via the following electronic interfaces:

                  3.4.1 When available, NEVADA Bell Order Dispatch (PBOD)
functions via DataGate will allow CLEC to check status of basic exchange service
orders that require field work.

                  3.4.2 In cases of EDI ordering, NEVADA will provide CLEC with
an EDI interface for transferring and receiving orders, Firm Order Confirmation
(FOC), service completion, and, as available, other provisioning data and
information. NEVADA will provide CLEC with a FOC for each Resale and UNE service
request. The FOC will include: purchase order number, telephone number, Local
Service Request number, due date, Service Order number, and completion date.
Upon work completion, NEVADA will provide CLEC with an 855 EDI transaction-based
Order Completion that states when that order was completed. CLEC may submit
supplement requests via the 860 EDI transaction, and, where available, NEVADA
will provide CLEC an 865 EDI transaction-based Completion notice.

4.       Maintenance/Repair

         4.1 Two real time electronic interfaces are accessible to place, and
check the status of trouble reports for both Resale and UNE. Upon request, CLEC
may access these functions via the following methods:

                  4.1.1 NEVADA Bell Service Manager (PBSM) allows CLECs to
perform NET, issue trouble tickets, view status, and view trouble history
on-line.

     4.1.2 Electronic Bonding Interface (EBI) is an interface that is available
for trouble report submission and status updates. This EBI conforms to ANSI
guidelines T1:227:1995 and T1.228:1995, Electronic. Communications
Implementation Committee (ECIC)
<PAGE>

Trouble Report Format Definition (TFRD) Number 1 as defined in ECIC document
ECICITRA/95-003, and all guidelines referenced within those documents, as
mutually agreed upon by CLEC and NEVADA. Functions currently implemented will
include Enter Trouble, Request Trouble- Report Status, Add Trouble Information,
Modify Trouble Report Attributes, Trouble Report Attribute Value Change
Notification, and Cancel Trouble Report, as explained in 6 and 9 of ANSI
TI.228:1995. CLEC and NEVADA will exchange requests over a mutually agreeable
X.25-based network.

5.       Billing

         5.1 NEVADA shall bill CLEC for resold services and UNE. NEVADA shall
send associated billing information to CLEC as necessary to allow CLEC to
perform billing functions. At minimum NEVADA will provide CLEC billing
information in a paper format or via magnetic tape, as agreed to between CLEC
and NEVADA.

     5.2 Electronic access to billing information for Resale Services will also
be available via the following interfaces:

                  5.2.1 NEVADA shall provide CLECs a Usage Extract Feed
electronically, on a daily basis, with information on the usage billed to its
accounts for resale services in the industry standardized Exchange Message
Record (EMR) format.

     5.3 Electronic access to billing information for UNE will also be available
via the following interfaces:

                  5.3.1 NEVADA makes available to CLECs a local Bill Data Tape
to receive data in an electronic format from its CABS database, the same
information that would appear on its paper bill.

                  5.3.2 NEVADA shall provide CLECs a Usage Extract Feed
electronically, on a daily basis, with information on the usage billed to its
accounts for UNE in the industry standardized Exchange Message Record (EMR)
format.

6.       Remote Access Facility

         6.1 CLEC must access the NEVADA OSS interfaces via the NEVADA Remote
Access Facility (PRAF). Connection to the PRAF will be established via a "port"'
either through dial-up or direct connection. CLEC may utilize a single port to
access these interfaces to perform the supported functions in NEVADA where CLEC
has executed an Appendix OSS and purchases System Access.
<PAGE>

7.       Operational Readiness Test (ORT) for Ordering/Provisioning and Repair/

         Maintenance Interfaces

         7.1 Prior to live access to interface functionality, the Parties must
conduct Operational Readiness Testing (ORT), which will allow for the testing of
the systems, interfaces, and processes for the OSS functions. ORT will be
completed in conformance with NEVADA requirements and implementation scheduling.

          7.2 Prior to live system usage, CLEC must complete user education
          classes for

NEVADA-provided interfaces that affect the NEVADA network. Classes are
train-the-trainer format to enable CLEC to devise its own course work for its
own employees. Charges will apply for each class. Classes will be available for
and required for PBSM, CESAR, LEX, and SORD.

          Optional classes will be available for Verigate and CLEO. Schedules
          will be made available

upon request and are subject to change. The length of classes vary; the
following table presents the applicable rates. Ongoing class schedules may be

</TABLE>

     7.3 A separate agreement will be required as a commitment to pay for a
specific

number of CLEC students in each class. CLEC agrees that charges will be billed
by NEVADA and CLEC payment is due 30 days later. CLEC agrees that personnel from
other competitive Local Service Providers may be scheduled into any class to
fill any seats for which the CLEC has not contracted. Class availability is
first-come, first served with priority given to CLECs who have not yet attended
the specific class.

         7.4 Class dates will based upon NEVADA availability and will be
coordinated between CLEC, NEVADA Account Manager and Product Management.

         7.5 CLEC agrees to pay cancellation fee of the full price noted in the
separate agreement if CLEC cancels scheduled classes less than two weeks prior
to the scheduled start date. CLEC agrees to provide to NEVADA completed
registration forms for each student no later than one week prior to the
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
                  applicable federal statutes and regulations) is not permitted
                  to be placed by CLEC in the Premises or in the Eligible
                  Structure. CLEC shall not use the Premises for office, retail,
                  or sales purposes. No signage or markings of any kind by CLEC
                  shall be permitted on the Eligible Structure or







                  on the grounds surrounding the Eligible Structure.

                                      226
<PAGE>

 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.

                                      227
<PAGE>

 11.7    CLEC Telecom Equipment, CLEC operating practices, or other activities
         or conditions attributable to CLEC that represent a significant
         demonstrable technical threat to NEVADA's network, equipment, or
         facilities, including the Eligible Structure, or to the network,
         equipment, or facilities of any person or entity located in the
         Eligible Structure, are strictly prohibited.

 11.8    Notwithstanding any other provision hereof, the characteristics and
         methods of operation of any equipment, facilities or any other item
         placed in the Premises shall not interfere with or impair service over
         NEVADA's network, equipment, or facilities, or the network, equipment,
         or facilities of any other person or entity located in the Eligible
         Structure; create hazards for or cause damage to those networks,
         equipment, or facilities, the Premises, or the Eligible Structure;
         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
         place or install in or on the Premises such fixtures and unpowered
         facilities as it shall deem desirable for the conduct of business.
         Personal property, fixtures and unpowered facilities placed by CLEC in
         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

                                      228
<PAGE>

shall consider a modification, improvement, addition, repair, or other
alteration requested by CLEC, provided that NEVADA shall have the right to
reject or modify any such request. NEVADA will perform any such construction,
and the associated cost shall be paid by CLEC in accordance with NEVADA's
thenstandard custom work order process.

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.

          (b) If a modification is made after this Appendix becomes part of an
          effective

         "Statement of Generally Available Terms and Conditions" or similar
         document for NEVADA (and the modification has not been included in a
         change to that "Statement" or this Appendix), 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

         resolving any objection made under Section 12.3(a) shall apply.

(c)      Notwithstanding Sections 17.3(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.

The terms and conditions expressly set forth in this Appendix shall control in
the event of an irreconcilable conflict with the Collocation Services Handbook
and the IJAH, or the NEBS Standards (including any modification to any of them
that can be objected to under this Section 12.3, regardless of whether CLEC
objected to such modification pursuant to Section 12.2). Notwithstanding the
immediately preceding, modifications that are governed by Section 12.3(c) shall
apply regardless of any conflict or inconsistency with any other term or
condition governing a Physical Collocation arrangement unless contrary to law.

         there are at least two entry points for NEVADA's cable facilities and
         at which space is available for new facilities in at least two of those
         entry points. CLEC is responsible for bringing its fiber optic cable to
         an accessible point outside of the Eligible Structure designated by
         NEVADA, and for leaving sufficient cable length in order for NEVADA to
         fully extend such CLECprovided cable to the Premises.

          14.4 NEVADA will not require CLEC to bring its own transmission
          facilities to the Eligible Structure in which CLEC seeks to Collocate.

                                      231
<PAGE>

14.5     Where existing space is available in the entrance facilities or
         equivalent for the Eligible Structure, NEVADA will permit intercon
         nection by copper or coaxial cable if CLEC can prove to the Commission

         interconnecting carriers.

          14.6 Upon request by CLEC, NEVADA will permit interconnection by
          microwave transmission facilities under an ICB arrangement.

14.7     Regeneration of either DS- I or DS-3 signal levels may be provided by
         CLEC or NEVADA under its then-standard custom work order process,
         including payment requirements prior to the installation of the
         regeneration equipment.

14.8     CLEC is responsible for removing any equipment, facilities, fixtures,
         personal property or other items, including the CLEC Telecom Equipment,
         that it brings into the Premises. If CLEC fails to remove such from the
         Premises within thirty (30) days after discontinuance of use, NEVADA
         may perform the removal and shall charge CLEC for any materials used in
         any such removal, and the time spent on such removal at the
         then-applicable hourly rate for custom work. Further, in addition to
         the other provisions herein, CLEC shall indemnify and hold NEVADA
         harmless from any and all claims, expenses, fees, or other costs
         associated with any such removal by NEVADA.

<PAGE>

NEVADA shall not require CLEC to use NEVADA's internal engineering or
installation work forces for the engineering and installation of the CLEC
Telecom Equipment). Installation of the CLEC Telecom Equipment in the Premises
must nevertheless comply with NEVADA's Installation and Job Acceptance Handbook.

 14.11   Each Party is responsible for immediate verbal notification to the
         other of significant outages or operations problems which could impact
         or degrade that other's network, equipment, facilities, or services,
         and for providing an estimated clearing time for restoration. In
         addition, written notification must be provided within twenty-four (24)
         hours.

     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
         defect in transmission or service occurs and continues. However, any

                                      234
<PAGE>

such mistakes, omissions, interruptions, delays, errors, or defects in

         special, consequential, lost profit, or punitive damages, whether in
         contract or tort.

 18.3    Each Party shall be indemnified and held harmless by the other against
         claims and damages by any third party arising from provision of the
         other Party's services or equipment except those claims and damages
         directly associated with the provision of services to the other Party
         which are governed by the provisioning Party's applicable tariffs.

 18.4    Neither Party shall have any liability whatsoever to the customers of
         the other Party for claims arising from the provision of the other
         Party's service to its customers, including claims for interruption of
         service, quality of service or billing disputes.

 18.5    The liability of either Party for its willful misconduct, if any, is
         not limited by this Appendix. With respect to any other claim or suit,
         by a customer or by any others, for damages associated with the
         installation, provision, preemption, termination, maintenance, repair
         or restoration of service, NEVADA's liability, if any, shall not exceed
         an amount equal to the proportionate monthly charge for the affected
         period.

 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
<PAGE>

     (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

         all of CLEC's personal property situated on or within the Eligible
         Structure or the Premises. CLEC releases NEVADA from and waives any and
         all right of recovery, claim, action or cause of action against NEVADA,
         its agents, directors, officers, employees, independent contractors,
         and other representatives for any loss or damage that may occur to
         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
         or the elements or any other risks would customarily be included in a
         standard all risk casualty insurance policy covering such property,
         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
         personal property are hereby waived.

 25.2     CLEC may also elect to purchase business interruption and contingent
          business interruption insurance, knowing that NEVADA has no liability
          for loss of profit or revenues should an interruption of service occur
          that is attributable to any Physical Collocation arrangement provided
          under this Appendix.

25.3     The limits set forth in this Section may be increased by NEVADA from
         time to time during the term of a Physical Collocation arrangement to
         at least such

                                      238
<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
                    and not contributing to or in excess of any similar coverage
                    purchased by NEVADA.

 25.5    All insurance must be in effect on or before occupancy date and shall
         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
         of, NEVADA's obligation to turn over the Premises to CLEC or to permit
         any CLEC-designated subcontractors into the Eligible Structure pursuant
         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.

 25.7    CLEC must also conform to recommendations made by NEVADA's Property
         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.

26.      PROTECTON OF SERVICE AND PROPERTY

 26.1    For the purpose of notice permitted or required by this Appendix, each
         Party shall provide the other Party a Single Point of Contact ("SPOC")
         available twenty-four (24) hours a day, seven (7) days a week.

26.2     Except as may otherwise be provided:

(a)      NEVADA and CLEC shall each exercise reasonable care to prevent harm

          or damage to the other Party, its employees, agents or customers, or
          their property, and

(a)      Each Party, its employees, agents, or representatives agree to take

         reasonable and prudent steps to ensure the adequate protection of
         property and services of the other Party.

                                      239
<PAGE>

          26.3 Each Party shall restrict access to the Eligible Structure and
          the Premises to employees and authorized agents of that other Party.

 26.4    NEVADA shall use electronic access controls to protect all spaces which
         house or contain CLEC equipment or equipment enclosures, but if
         electronic controls are not available, NEVADA shall either furnish
         security guards at those NEVADA locations already protected by security
         guards on a seven (7) day per week, twenty-four (24) hour a day basis;
         and if none, NEVADA shall permit CLEC to install monitoring equipment
         in the collocation space to carry data back to CLEC's work center for
         analysis. CLEC agrees that CLEC is responsible for problems or alarms
         related to CLEC's equipment or equipment enclosures located on NEVADA's
         premises.

          26.5 NEVADA shall furnish CLEC with samples of the identifying
          credentials to be carried by its employees and authorized agents.

26.6     CLEC shall furnish NEVADA with samples of the identifying credentials
         to be carried by its employees and authorized agents.

26.7     CLEC shall comply with the security and safety procedures and
         requirements of NEVADA, including but not limited to sign-in,
         identification and escort requirements.

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
         codes, lock combinations, or other materials or information which may
         be needed to gain entry into any secured CLEC space. In the event of an
         emergency, CLEC shall contact a SPOC provided by NEVADA for access to
         spaces which house or contain CLEC equipment or equipment enclosures.
         Such NEVADA SPOC shall be available to receive calls from CLEC
         twenty-four (24) hours a day, seven (7) days a week and make access
         available to CLEC within three (3) hours after receiving a call from
         CLEC within the Reno Metropolitan area and within a timeframe to be
         negotiated for all other offices.

 26.9    Keys used in NEVADA's keying systems for spaces which contain or house
         CLEC equipment or equipment enclosures shall be limited to NEVADA
         employees and representatives for emergency access only. CLEC shall
         have the right to require NEVADA to change locks at NEVADA's expense
         where there is evidence of inadequate security. In all other cases,
         CLEC may require NEVADA to change locks at CLEC's expense.

                                      240
<PAGE>

 26.10   NEVADA shall use reasonable measures to control unauthorized access
         from passenger and freight elevators to spaces which contain or house
         CLEC equipment or equipment enclosures.

 26.11   NEVADA shall use best efforts to provide notification within two (2)
hours to designated CLEC personnel to indicate an
         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.

 26.13   CLEC security personnel may audit the collocation area at a
         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.

28.      MISCELLANEOUS

 28.1    NEVADA shall protect as proprietary to CLEC all information provided by
         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
         of this Appendix, including having any past due charges hereunder. In
         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
 are not intended to affect the meaning or
         interpretation of this Appendix.

 28.6    Whenever this Appendix requires the consent of a Party, any request
 for such consent shall be in writing.

 28.7    Neither Party shall be deemed to have waived or impaired any right,
         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
         multiple End Users onto a single service.

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
         situated customers who are eligible for

                                      257
<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
         ordinary rate for a retail service rather than a special promotional
         rate when such promotions will be in effect for no more than 90 days.

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
         herein only in those service

                                      258
<PAGE>

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.

3.       ANCILLARY SERVICES

91 1/E911

 3.1.1   Where available, NEVADA will afford CLEC End Users with the ability to
         make 911 calls. CLEC shall be responsible for collecting and remitting
         all applicable 911 surcharges on a per line basis to the Public Safety
         Answering Point ("PSAP").

         3.1.2    When requested by NEVADA, CLEC shall provide timely, accurate
                  and complete information on each of CLEC's End Users as needed
                  for the

                  provisioning-of 911 service to CLEC's End Users. Such
                  information shall be in a format and a time frame prescribed
                  by NEVADA for purposes of 911 administration.

3.2      White Page Directories: Listings, Distribution & Information Page

 3.2.1   NEVADA shall provide, at no additional charge, a basic listing of
         CLEC's End User in the appropriate NEVADA local White Pages. Subscriber
         listing information on resold lines shall remain the property of
         NEVADA.

         3.2.1.1     Upon receipt of a request from a third party directory
                     publisher, including Nevada Bell Yellow Pages, for
                     subscriber listing information, NEVADA will provide to that
                     third party directory publisher CLEC subscriber's listing
                     information on an interfiled basis and indistinguishable
                     from NEVADA's subscriber listing information.

 3.2.1.2    Each CLEC subscriber will receive one copy of NEVADA's White Pages
            directory, and a Yellow Pages directory when cobound with the White
            Pages, in the same manner and at the same time that they are
            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
            shall not be required to deliver a directory to that End User until
            new directories are published for that End User's location.

                                      260
<PAGE>

                  3.2.1.4    The listings described above are included in the
                             wholesale price CLEC owes NEVADA for resold lines
                             and will be provided by NEVADA at no additional
                             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

         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.

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

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

         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.

         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.

                                      265
<PAGE>

                  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.

                                      266
<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

          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
         (GR-317-CORE, GR-394-CORE, GR-444-Core, GR-606-CORE, GR-82-CORE,
         GR-905-CORE and various other documents) and defined by NEVADA's
         Technical Publication L-780023 PB/LB.

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.

4.       DESCRIPTION OF RATE ELEMENTS

Where applicable the following rate elements apply to SS7 Service:
4.1 SS7 Transport
    -------------


4. 1.1   SS7 Transport shall be measured per octet of information screened and
routed.

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
           excess cable necessary to reach a NEVADA frame in the NEVADA central
           office where CLEC requests connection.

          2.9.2 The following terms and conditions apply when NEVADA provides
          access pursuant Sections 2.9. 1. 1 through 2.9.1.5:

2.9.2.1 The terms and conditions for CLECs choosing to access NEVADA's

            UNEs through physical collocation arrangements are set forth in
Appendix PHYSICAL COLLOCATION.

               2.9.2.2 Within ten (10) business days of receipt of a written
                    request for access to

            UNEs involving three (3) or fewer central offices, NEVADA will
            provide a written reply notifying the requesting CLEC of the
            method(s) of access available in the requested central offices. For
            requests

               2-9-2.3 Access to UNEs via Method 1 and Method 2 are only
                    available to physically collocated CLECs.

 2.9-2.4    Method 3, Method 4, and Method 5 are available to both collocated
            and non-collocated CLECs. Methods 2, 3, and 4 are subject to the
            availability of space and equipment.

 2.9.2.5    For requests concerning three (3) or fewer central offices, if the
            agreedupon method of access is not available, NEVADA will within
            ninety (90) business days (or the interval established under a
            request for physical collocation, if applicable) prepare the wire
            center for access to UNEs. For requests impacting four (4) or more
            central offices, the Parties will agree to an implementation
            schedule.

 2.9.2.6    The CLEC may cancel the request at any time, but will pay NEVADA's
            reasonable and demonstrable costs for modifying or making additions
            to its network up to the date of cancellation.

 2.9.2.7    A CLEC electing to exercise Method 5 shall perform all construction,
            cabling, and connection work required to reach the NEVADA manhole
            nearest the subject NEVADA Central Office, including the excess
            cable as outlined in 2.9.1.5. CLEC shall obtain all necessary rights
            of way, easements, and other third party permissions.

 2.9.2.8    CLEC shall be responsible for initial testing and sectionalization
            of facilities containing CLEC installed cross connects.

 2.9.2.9    CLEC shall refer trouble sectionalized in the NEVADA UNE to NEVADA.

 2.9.2.     10 Prior to NEVADA providing access to UNEs under this Appendix,
            CLEC and NEVADA shall provide each other with a point of contact for
            overall coordination.

 2.9.2.11   CLEC shall provide all tools and materials required to place and
            remove the cross connects necessary to combine and disconnect UNEs.

 2.9.2.13   CLEC shall be responsible for CLEC's p ersonnel observing NEVADA's
            site rules and regulations, including but not limited to safety
            regulations and security requirements, and for working in harmony
            with others while present at the site. If NEVADA for any reasonable
            and lawful reason requests CLEC to discontinue furnishing any person
            provided by CLEC for performing work on NEVADA's premises, CLEC
            shall immediately comply with such request. Such person shall leave
            NEVADA's premises promptly, and CLEC shall not furnish such person
            again to perform work on NEVADA's premises without NEVADA's consent.

               2.9.2.14 CLEC shall provide positive written acknowledgment that
                    the requirements stated in Section 2.9.2.13 have been
                    satisfied for each employee requiring access to NEVADA
                    premises and/or facilities. NEVADA identification cards will
                    be issued for any CLEC employees who are designated by CLEC
                    as meeting the necessary requirements for access. Entry to
                    NEVADA premises will be granted only to CLEC employees with
                    such identification.

 2.9.2.15   CLEC shall designate each network element being ordered from NEVADA.
            CLEC shall provide an interface to receive assignment information
            from NEVADA regarding location of the extended UNEs. This interface
            may be manual or mechanized.

 2.9.2.16   NEVADA will provide CLEC with contact numbers as necessary to
            resolve assignment conflicts encountered. All contact with NEVADA
            shall be referred to such contact numbers.

2.9.2.17    The CLEC shall provide its own administrative telecommunication
            service at each facility and all materials needed by CLEC at the
            work site. The use of Cellular Telephones is not permitted in NEVADA
            equipment areas.

 2.9.2.18   Certain construction and preparation activities may be required to
            modify a building or prepare the premises for access to Unbundled
            Network Elements.

 2.9.2.18.1   Where applicable, a one time preparation charge for modifying a
              building or preparing the premises will be made on an individual
              case basis (ICB). Within 30 days of a request by a CLEC, NEVADA
              will provide an initial estimate of time for preparing the ICB.

                                      322
<PAGE>

 2.9.2.18.2   NEVADA will contract for and perform the construction and
              preparation activities using same or consistent practices that are
              used by NEVADA for other construction and preparation work
              performed in the building.

 2.9.2.18.3   The first entity to which NEVADA provides access to Unbundled
              Network Elements the building shall be responsible for all costs
              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

       1st                           100%                     NA
       2 nd                           50%                     50%
       3rd                          33 1/3%                 16 2/3%
       4 th                           25%                    81.3%
50 and beyond                         0%                      0%

No interest will be paid on refunds. Refunds shall be based on the Initial
Common Charge actually paid by the first CLEC. Notwithstanding the above, NEVADA
shall have no obligation to remit any amount that would result in NEVADA being
unable to retain the full amount of the Initial Common Charge or to remit any
amount based upon charges not actually collected.

2.9.2.18.4    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" intrastate tariff late payment
              provision(s) applicable to access services in Nevada, or the
              highest rate permitted by law, whichever is lower, from the due
              date until paid.

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

          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

         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

     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.

         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);

(c)      rearrangement/modification (Change); or

(d)      cancellation (per NEVADA's tariff P.S.C.N. C, Section 5).

12.5     Maintenance of Elements

12.5.1 The network elements provided by NEVADA pursuant to this Appendix will be
maintained by NEVADA.

                                      339
<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.

APPENDIX WP

WHITE PAGES DIRECTORY APPENDIX

NEVADA and CLEC agree to the following terms and conditions for the printing and
distribution of White Pages directories:

(a)  NEVADA publishes White Pages directories for geographic areas in which CLEC
     also

         provides local exchange telephone service, and CLEC wishes to include
         listings information for its End Users in the appropriate NEVADA White
         Pages directories.

(b)  CLEC also desires distribution to its End Users of the White Pages
     directories that

         include listings of CLEC's End Users.

NOW THEREFORE, in consideration of these premises, NEVADA and CLEC agree as
follows:

1.       SERVICE PROVIDED

1.1  Subject to NEVADA's practices, as well as the rules and regulations
     applicable to

         the provision of White Pages directories, NEVADA will include in
         appropriate White Pages directories the primary alphabetical listings
         of all CLEC End Users located within the local directory scope. The
         rules, regulations and NEVADA practices are subject to change from time
         to time.

1.2  CLEC shall furnish to NEVADA, in a form acceptable to both Parties,
     subscriber

         listing information pertaining to CLEC End Users located within the
         local directory scope, along with such additional information as NEVADA
         may require to prepare and print the alphabetical listings of said
         directory.

1.3      CLEC may provide CLEC's subscriber listing information to NEVADA for

         inclusion in the White Pages directory via an electronic feed of the
         listing information to NEVADA's listing database. Upon receipt of a
         request from a third party directory publisher, including Pacific Bell
         Directory, for subscriber listing information, NEVADA will provide to
         that third party directory publisher CLEC subscriber's listing
         information on an alphabetically Interfiled (interspersed) basis and
         indistinguishable from NEVADA's subscriber listing information. CLEC is
         responsible in using all available information to validate CLEC's End
         User listings for the directory(ies) prior to the directory(ies)
         deadline.

1.4  CLEC must provide a Main Listing (whether the End User's number is to be
     published or non-published) for each end-user that requires delivery.
     NEVADA

                                      345
<PAGE>

will arrange for the delivery of local directories to CLEC end-users in
accordance with current practices.

1.5      Each CLEC subscriber will receive one copy of NEVADA's White Pages

         directory, and a Yellow Pages directory when cobound with the White
         Pages, in the same manner and at the same time that they are provided
         to NEVADA's subscribers.

 1.6     If CLEC's End User already has a current NEVADA directory, NEVADA shall
         not be required to deliver a directory to that End User until new
         directories are published for that End User's location.

         1.7      At CLEC's request, NEVADA will include CLEC specific
                  information (i.e., business office, residence office, repair
                  bureau, etc.) in the White Pages directory on an "index-type"
                  informational page. This page will also include specific
                  information pertaining to other CLECs. At its option, CLEC
                  shall provide NEVADA with its logo and information in the form
                  of a camera ready copy, sized at 1/8h of a page.

2.       USE OF SUBSCRIBER LISTING INFORMATION

CLEC authorizes NEVADA or its affiliated directory publisher to use the
subscriber listing information provided to NEVADA pursuant to this Appendix, for
inclusion in the appropriate printed directories and directory assistance
databases where such service is provided by NEVADA.

Note: NEVADA uses CLEC and NEVADA listings to update/publish the Directory
     Assistance Data Base and the WP directory(ies).

3.       PRICING

3.1  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. The rates for additional
     listing services described herein are identified in NEVADA's tariff rates
     as defined in P.S.C.N. A5.

 3.2     Where CLEC's End User requires additional listings to appear in the
         White Pages directory, NEVADA will assess CLEC a monthly charge for
         such listings at existing NEVADA tariff rates as defined in P.S.C.N.
         A5.

                                      346
<PAGE>

4.       ASSIGNMENT

         The subscriber listing information shall remain the property of CLEC.
         Except as stated in Section -a herein, NEVADA shall not sublicense,
         assign, sell or transfer the subscriber listing information provided
         hereunder, nor shall NEVADA authorize any other company, outside the
         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
         NEVADA for reasonable attorney's fees and other expenses incurred by
         NEVADA in handling and defending such demand, claim and/or suit.

 5.3     This Appendix shall not establish, be interpreted as establishing, or
         be used by either party to establish or to represent their relationship
         as any form of agency, partnership or joint venture. Neither party
         shall have any authority to bind the other or to act as an agent for
         the other unless written authority, separate from this Appendix, is
         provided. Nothing in the Appendix shall be construed as providing for
         the sharing of profits or losses arising out of the efforts of either
         or both of the Parties. Nothing herein shall be construed as making
         either Party responsible or liable for the obligations and undertakings
         of the other Party.

                                      347
<PAGE>

6.       BREACH-OF CONTRACT

If either Party is found to have materially breached this Appendix, the
non-breaching Party may terminate the Appendix by providing written notice to
the breaching party, whereupon this Appendix shall be null and void with respect
to any issue of NEVADA'S White Pages directory published sixty (60) or more days
after the date of the receipt of such written notice.

                      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

                   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.

                           INTERCONNECTION AGREEMENT

  THIS INTERCONNECTION AGREEMENT is between Pac-West Telecomm, Inc. ("Pac-West")
and U S WEST Communications, Inc. ("USWC"), a Colorado corporation.

I.  RECITALS

     Pursuant to this Interconnection Agreement Pac-West Telecomm, Inc. ("Pac-
     West") and U S WEST Communications, Inc. ("USWC"), collectively "the
     Parties", will extend certain arrangements to one another within each LATA
     in which they both operate within this State. This Agreement is a
     combination of agreed terms and terms imposed by arbitration under Section
     252 of the Communications Act of 1934, as modified by the
     Telecommunications Act of 1996 ("the Act"), and as such does not
     necessarily represent the position of either Party on any given issue. The
     Parties enter into this Agreement without prejudice to any position they
     may have taken previously, or may take in the future in any legislative
     regulatory, or other public forum addressing any matters, including matters
     related to the types of arrangements prescribed by this Agreement.

II.  SCOPE OF AGREEMENT

     A.   This Agreement sets forth the terms, conditions and prices under which
          USWC agrees to provide (a) services for resale (hereinafter referred
          to as "Local Services") (b) certain Unbundled Network Elements,
          Ancillary Functions and additional features to Pac-West (hereinafter
          collectively referred to as "Network Elements") or combinations of
          such Network Elements ("Combinations") for Pac-West's own use or for
          resale to others.  The Agreement also sets forth the terms, conditions
          and prices under which the parties agree to provide interconnection
          and reciprocal compensation for the exchange of local traffic between
          USWC and Pac-West for purposes of offering telecommunications
          services.  Unless otherwise provided in this Agreement, the parties
          will perform all of their obligations hereunder throughout, to the
          extent provided in the Appendices attached hereto.  The Agreement
          includes all accompanying appendices.

     B.   In the performance of their obligations under this Agreement, the
          Parties shall act in good faith and consistently with the intent of
          the Act.  Where notice, approval or similar action by a Party is
          permitted or required by any provision of this Agreement, (including,
          without limitation, the obligation of the parties to further negotiate
          the resolution of new or open issues under this Agreement) such action
          shall not be unreasonably delayed, withheld or conditioned.

     C.   When Pac-West begins offering residential and business exchange
          services in this state through the use of Pac-West's facilities, Pac-
          West will notify USWC.

     D.   Acknowledgment of Deferred Issues:

               Pac-West acknowledges it is USWC's position that USWC's existing
               telecommunications network represents substantial investment made
               as a result of its carrier-of-last-resort obligation and that
               such network allows

                                                                          Page 1
<PAGE>

               Pac-West's end users to interconnect with significantly more
               business and residential customers than vice versa. Pac-West
               further acknowledges USWC believes that a separate transitional
               element is necessary to compensate USWC for the value of its
               network in this Agreement, that under the Act, the FCC will
               establish a proceeding to address Universal Service Support, and
               that the Act also empowers the state Commission to establish a
               separate proceeding on universal service issues. Pac-West further
               acknowledges that USWC believes that USWC is entitled to receive
               additional compensation for costs of implementing various
               provisions of the Act, and that USWC shall seek such additional
               recovery through future state and/or federal regulatory
               proceedings. Pac-West disagrees with these USWC positions.

               USWC acknowledges it is Pac-West's position that the relative
               investments of the Parties is not a relevant consideration in the
               context of this agreement and that it is the result of a
               historical monopoly which confers significant, continuing
               benefits on USWC. USWC acknowledges that it is Pac-West's
               position that no transitional elements are necessary to
               compensate USWC, that any such transitional elements would
               constitute a windfall to USWC, and that the investigations
               contemplated at the State and federal level for Universal Service
               Funding will substantially disprove USWC's claims. USWC further
               acknowledges that Pac-West believes that the costs of
               implementing the Act are costs experienced by all
               telecommunications carriers and that it would be unjust,
               discriminatory, and anti-competitive to favor USWC with
               additional cost recovery of implementation costs. USWC disagrees
               with these Pac-West positions.

               In consideration of Pac-West's willingness to interconnect on the
               terms set forth in this Agreement, and without prejudice to the
               position it may take in the FCC docket or before any state
               Commission, USWC agrees to await the outcome of such proceedings,
               rather than seek universal service support from Pac-West at this
               time.

II.  "Party" means either USWC or Pac-West and "Parties" means USWC and Pac-
     West.

JJ.  "Port" means a termination on a Central Office Switch that permits
     customers to send or receive telecommunications services over the public
     switched network, but does not include switch features or switching
     functionality.

KK.  "Rate Center" means the specific geographic point and corresponding
     geographic area which are associated with one or more particular NPA-NXX
     codes which have been assigned to a LEC (or CLEC) for its provision of
     basic exchange telecommunications services.  The "rate center point" is the
     finite geographic point identified by a specific V & H coordinate, which is
     used to measure distance-sensitive end user traffic to/from, the particular
     NPA-NXX designations associated with the specific Rate Center.  The "rate
     center area" is the exclusive geographic area identified as the area within
     which the LEC (or CLEC) will provide Basic Exchange Telecommunications
     Service bearing the particular NPA-NXX designations associated with the
     specific Rate Center.  The Rate Center point must be located within the
     Rate Center area.

LL.  "Reseller" is a category of Local Exchange service provider that obtains
     dial tone and associated telecommunications services from another provider
     through the purchase of bundled finished services for resale to its end use
     customers.

MM.  Service Control Point" or "SCP" means a signaling end point that acts as a
     database to provide information to another signaling end point (i.e.,
     Service Switching Point or another SCP) for processing or routing certain
     types of network calls.  A query/response mechanism is typically used in
     communicating with an SCP.

NN.  "Signaling Transfer Point" or "STP" means a signaling point that performs
     message routing functions and provides information for the routing of
     messages between signaling end points.  An STP transmits, receives and
     processes Common Channel Signaling ("CCS") messages.

OO.  "Switched Exchange Access Service" means the offering of transmission or
     switching services to Telecommunications Carriers for the purpose of the
     origination or termination of Telephone Toll Service.  Switched Exchange
     Access Services include:  Feature Group A, Feature Group B, Feature Group
     D, 800/888 access, and 900 access and their successors or similar Switched
     Exchange Access services.

PP   "Traffic Type" is the characterization of intraLATA traffic as "local"
     (local includes EAS), or "toll" which shall be the same as the
     characterization established by the effective tariffs of the incumbent
     local exchange carrier as of the date of this agreement.

QQ.  "Wire Center" denotes a building or space within a building, that serves as
     an aggregation point on a given carrier's network, where transmission
     facilities are connected or switched.  Wire Center can also denote a
     building where one or more Central Offices, used for the provision of Basic
     Exchange Telecommunications Services and Access Services, are located.
     However, for purposes of Collocation Service, Wire

                                                                          Page 6

     in the FCC Docket No. 91-141, and rules adopted pursuant thereto.

RR.  "Routing Point" means a location that a LEC or CLEC has designated on its
     own network as the homing (routing) point for traffic, bearing a certain
     NPA-NXX designation, that is inbound to Basic Exchange Telecommunications
     Services provided by the LEC or CLEC.  The Routing Point is employed to
     calculate mileage measurements for the distance-sensitive transport element
     charges of Switched Access Services.  Pursuant to Bellcore Practice BR 795-
     100-100, the Routing Point may be an "End Office" location, or a "LEC
     Consortium Point of Interconnection".  Pursuant to that same Bellcore
     Practice, examples of the latter shall be designated by a common language
     location identifier (CLLI) code with (x)KD in positions 9, 10, 11, where
     (x) may be any alphanumeric A-Z or 0-9.  The above referenced Bellcore
     document refers to the Routing Point as the Rating Point.  The Rating
     Point/Routing Point need not be the same as the rate center point nor must
     it be located within the rate center area,  but must be in the same LATA as
     the NPA/NXX.  Pac-West may not employ its use of a single point of
     interconnection to avoid paying USWC for use of its transport and tandem
     facilities.  See also Section V.E. and Appendix A Note 1./1/

SS.  "Tariff Services" as used throughout this Agreement refers to the
     applicable Party's interstate tariffs and state tariffs, price lists, price
     schedules and catalogs.

TT.  "Information Service Traffic" means Local Traffic or IntraLATA Toll Traffic
     which originates on a Telephone Exchange Service line and which is
     addressed to an information service provided over a Party's information
     services platform (e.g., 976).
                        ----

IV.  RATES AND CHARGES  GENERALLY


     A.   Prices for termination and transport of traffic, interconnection,
          access to unbundled network elements, and ancillary services are set
          forth in Appendix A.

     B.   USWC's wholesale discounts for resale services are set forth in
          Appendix A.

     C.   The underlying provider of a resold service shall be entitled to
          receive, from the purchaser of switched access, the appropriate access
          charges pursuant to its then effective switched access tariff.  For
          the purposes of this paragraph, Unbundled Loops are not considered as
          resold services.

                                                                          Page 8

V.   RECIPROCAL TRAFFIC EXCHANGE


     A.   Scope

          Reciprocal traffic exchange addresses the exchange of traffic between
          Pac-West end users and USWC end users.  If such traffic is local, the
          provisions of this Agreement shall apply.  Where either party acts as
          an intraLATA toll provider or interLATA Interexchange Carrier (IXC) or
          where either party interconnects and delivers traffic to the other
          from third parties, each party shall bill such third parties the
          appropriate charges pursuant to its respective tariffs or contractual
          offerings for such third party terminations.  Absent a separately
          negotiated agreement to the contrary, the Parties will directly
          exchange traffic between their respective networks, without the use of
          third party transit providers.

     B.   Types of Traffic

          The types of traffic to be exchanged under this Agreement include:

          1.   EAS/local traffic as defined above.

          2.   IntraLATA toll traffic as defined above.

          3.   Switched access traffic, or interLATA toll traffic, as
               specifically defined in USWC's state and interstate switched
               access tariffs, and generally identified as that traffic that
               originates at one of the Party's end users and terminates at an
               IXC point of presence, or originates at an IXC point of presence
               and terminates at one of the Party's end users, whether or not
               the traffic transits the other Party's network.

          4.   Transit traffic is any traffic other than switched access, that
               originates from one Telecommunications Carrier's network,
               transits another Telecommunications Carrier's network, and
               terminates to yet another Telecommunications Carrier's network.

               Transit service provides the ability for a Telecommunications
               Carrier to use its connection to a local or access tandem for
               delivery of calls that originate with a Telecommunications
               Carrier and terminate to a company other than the tandem company,
               such as another Competitive Local Exchange Carrier, an existing
               Exchange Carrier, or a wireless carrier.  In these cases, neither
               the originating nor terminating end user is a customer of the
               tandem Telecommunications Carrier.  The tandem Telecommunications
               Carrier will accept traffic originated by a Party and will
               terminate it at a point of interconnection with another local,
               intraLATA or interLATA network Telecommunications Carrier.  This
               service is provided through local and access tandem switches.

                                                                          Page 9
<PAGE>

          5.   Ancillary traffic includes all traffic destined for ancillary
               services, or that may have special billing requirements,
               including, but not limited to the following:

               a.  Directory Assistance
               b.  911/E911
               c.  Operator call termination (busy line interrupt and verify)
               d.  800/888 database dip
               e.  LIDB
               f.  Information services requiring special billing.

          6.   Unless otherwise stated in this Agreement, ancillary traffic will
               be exchanged in accordance with whether the traffic is Local/EAS,
               intraLATA toll, or Switched Access.

     C.   Types of Exchanged Traffic

          1.   Termination of Local Traffic.

               Local traffic will be terminated as Local Interconnection Service
               (LIS).

          2.   Transport of Local Traffic

               As negotiated between the Parties, the exchange of local traffic
               between the Parties may occur in several ways:

               a.   While the parties anticipate the use of two way trunks for
                    the delivery of local traffic, either Party may elect to
                    provision its own one-way trunks for delivery of local
                    traffic to be terminated on the other Party's network at the
                    "initial" point of interconnection.

               b.   The Parties may elect to purchase transport services from
                    each other or from a third party. Such transport delivers
                    the originating Party's local traffic to the terminating
                    Party's end office or tandem for call termination. Transport
                    may be purchased as either tandem switched transport (which
                    is included in the tandem call termination rate) or direct
                    trunk transport.

               c.   Based on forecasted traffic at Pac-West's busy hour in CCS,
                    where there is a DS1's worth of traffic (512 CCS) between
                    the Pac-West switch and a USWC end office, the Parties agree
                    to provision a dedicated (i.e., direct) two-way trunk group
                    from the Pac-West switch directly to the USWC end office.
                    To the extent that Pac-West has established a collocation
                    arrangement at a USWC end office location, and has available
                    capacity, the Parties agree that Pac-West shall provide two-
                    way direct trunk facilities, when required, from that end
                    office to the Pac-West switch.  In all other cases, the
                    direct facility may be provisioned by USWC or Pac-West or a
                    third party.  If both Pac-West and USWC desire to

                                                                         Page 10
<PAGE>

                    provision the facility and cannot otherwise agree, the
                    parties may agree to resolve the dispute through the
                    submission of competitive bids.

          3.   Transit Traffic.

               a.   USWC will accept traffic originated by Pac-West and will
                    terminate it at a point of interconnection with another
                    CLEC, Exchange Carrier, Interexchange Carrier or Wireless
                    Carrier.  USWC will provide this transit service through
                    local and access tandem switches.  Pac-West may also provide
                    USWC with transit service.

               b.   The Parties expect that all networks involved in
                    transporting transit traffic will deliver calls to each
                    involved network with CCS/SS7 protocol and the appropriate
                    ISUP/TCAP message to facilitate full interoperability and
                    billing functions.  In all cases, the originating company is
                    responsible to follow the EMR standard and to exchange
                    records with both the transiting company and the terminating
                    company, to facilitate the billing process to the
                    originating network.

               c.   The Parties will use industry standards developed to handle
                    the provision and billing of Switched Access by multiple
                    providers (MECAB, MECOD and the Parties' FCC tariffs),
                    including the one-time provision of notification to Pac-West
                    of the billing name, billing address and carrier
                    identification codes of all interexchange carriers
                    originating or terminating at each USWC access tandem.

          4.   Toll Traffic.

               a.   Toll traffic routed to an access tandem, or directly routed
                    to an end office, will be terminated as Switched Access
                    Service.  Traffic terminated at the access tandem will be
                    routed to the end offices within the LATA that subtend the
                    USWC access tandem switch.  Switched Access Service also
                    allows for termination at an end office or tandem via direct
                    trunked circuits provisioned either by USWC or Pac-West.

     D.   Rate Structure -- Local Traffic

          1.   Call Termination

               a.   The Parties agree that call termination rates as described
                    in Appendix A will apply reciprocally for the termination of
                    local/EAS traffic per minute of use.

               b.   For traffic terminated at an USWC or Pac-West end office,
                    the end office call termination rate in Appendix A shall
                    apply.

                                                                         Page 11
<PAGE>

               c.   For traffic terminated at a USWC or Pac-West tandem switch,
                    the tandem call termination rate in Appendix A shall apply.
                    The tandem call termination rate provides for end office
                    call termination, tandem switched transport and tandem
                    switching.

                    The Parties acknowledge that Pac-West will initially serve
                    all of its customers within a given LATA through a single
                    Pac-West switch.  The Parties also acknowledge that Pac-West
                    may, in the future, deploy additional switches in each
                    LATA..

               d.   For purposes of call termination, the initial Pac-West
                    switch shall be treated as an end office switch./2/

               e.   Pursuant to OPUC Decision 96-324, USWC's proposed paragraph
                    e. has been deleted.



          2.   Transport

               a.   If the Parties elect to each provision their own one-way
                    trunks to the other Party's end office for the termination
                    of local traffic, each Party will be responsible for its own
                    expenses associated with the trunks and no transport charges
                    will apply. Call termination charges shall apply as
                    described above.

               b.   If one Party desires to purchase direct trunk transport from
                    the other Party, the following rate elements will apply.
                    Transport rate elements include the direct trunk transport
                    facilities between the POI and the terminating party's
                    tandem or end office switches.. The applicable rates are
                    described in Appendix A.

               c.   Direct-trunked transport facilities are provided as
                    dedicated DS3 or DS1 facilities without the tandem switching
                    functions, for the use of either Party between the point of
                    interconnection and the terminating end office or tandem
                    switch.

               d.   If the Parties elect to establish two-way direct trunks, the
                    compensation for such jointly used `shared' facilities shall
                    be adjusted as follows.  The nominal compensation shall be
                    pursuant to the rates for direct trunk transport in Appendix
                    A.  The actual rate paid to the provider of the direct trunk
                    facility shall be reduced to reflect the provider's use of
                    that facility.  The adjustment in the direct trunk transport
                    rate shall be a percentage that reflects the provider's
                    relative use (i.e., originating minutes of use) of the
                    facility in the busy hour.

______________________
/2/ This sentence has been included pursuant to OPUC Decision 96-324.

                                                                         Page 12

               e.   Multiplexing options are available at rates described in
                    Appendix A.

     E.   Rate Structure -- Toll Traffic.

          1.   Applicable Switched Access Tariff rates, terms, and conditions
               apply to toll traffic routed to an access tandem, or directly to
               an end office.  Relevant rate elements include Direct Trunk
               Transport (DTT) or Tandem Switched Transport (TST),
               Interconnection Charge (IC), Local Switching, and Carrier Common
               Line, as appropriate.

     F.   Rate Structure -- Transit Traffic.

          1.   Applicable switched access, Type 2 or LIS transport rates apply
               for the use of USWC's network to transport transit traffic.  For
               transiting local traffic, the applicable local transit rate
               applies to the originating party per Appendix A.  For transiting
               toll traffic, the Parties will charge the applicable switched
               access rates to the responsible carrier.  For terminating
               transiting wireless traffic, the Parties will charge their
               applicable rates to the wireless provider.  For transiting
               wireless traffic, the parties will charge each other the
               applicable local transit rate.

     G.   LIS Interface Code Availability And Optional Features

          1.   Interface Code Availability.

               Supervisory Signaling specifications, and the applicable network
               channel interface codes for LIS trunks, are the same as those
               used for Feature Group D Switched Access Service, as described in
               the Parties' applicable switched access tariffs.

          2.   Optional Features.

               a.   Inband MF or SS7 Out of Band Signaling.

                    Inband MF signaling and SS7 Out of Band Signaling are
                    available for LIS trunks.  MF signaling or SS7 Out-of-Band
                    Signaling must be requested on the order for the new LIS
                    trunks.  Provisioning of the LIS trunks equipped with MF
                    signaling or SS7 Out of Band Signaling is the same as that
                    used for Feature Group D Switched Access.  Common Channel
                    Signaling Access Capability Service, as set forth in Section
                    XXVIII herein, must be ordered by Pac-West when SS7 Out-of-
                    Band Signaling is requested on LIS trunks.

                                                                         Page 13

               b.   Clear Channel Capability.

                    Clear Channel Capability permits 24 DS0-64 kbit/s services
                    or 1.536 Mbit/s of information on the 1.544 Mbit/s line
                    rate.  Clear Channel Capability is available for LIS trunks
                    equipped with SS7 Out-of-Band Signaling.  Clear Channel
                    Capability is only available on trunks to USWC's access
                    tandem switch or USWC's end office switches (where
                    available); (Clear Channel Capability is not available on
                    trunks to USWC's local tandem switches or end offices where
                    it is currently not deployed.  Pac-West agrees to use the
                    Network Interconnection and Unbundled Element Request
                    process to request clear channel capability for such
                    additional switches.  Prices for such additional clear
                    channel capability, if any, will be established through the
                    NIUER Process).  Clear Channel Capability must be requested
                    on the order for the new LIS trunks.  The provisioning of
                    the LIS trunks equipped with Clear Channel Capability is the
                    same as that used for Feature Group D Switched Access
                    Service.  USWC will provide Pac-West with a listing of USWC
                    end offices, local tandems and access tandems equipped with
                    clear channel capability.

     H.   Measuring Local Interconnection Minutes

          1.   Measurement of terminating Local Interconnection Minutes begins
               when the terminating LIS entry switch receives answer supervision
               from the called end user's end office indicating the called end
               user has answered.  The measurement of terminating call usage
               over LIS trunks ends when the terminating LIS entry switch
               receives disconnect supervision from either the called end user's
               end office, indicating the called end user has disconnected, or
               Pac-West's point of interconnection, whichever is recognized
               first by the entry switch.


          2.   USWC and Pac-West are required to provide each other the proper
               call information (e.g., originated call party number and
               destination call party number, etc.) to enable each Party to
               issue bills in a complete and timely fashion.

     I.   Testing

          1.   Acceptance Testing

               At the time of installation of an LIS trunk group, and at no
               additional charge, the Parties will cooperatively test the same
               parameters tested for  terminating Feature Group D Switched
               Access Service.  Please see USWC's applicable switched access
               tariff for the specifications.

                                                                         Page 14
<PAGE>

          2.   Testing Capabilities

               a.   Terminating LIS testing is provided where equipment is
                    available, with the following test lines: seven-digit access
                    to balance (100 type), milliwatt (102 type), nonsynchronous
                    or synchronous, automatic transmission measuring (105 type),
                    data transmission (107 type), loop-around, short circuit,
                    open circuit, and non-inverting digital loopback (108 type).

               b.   In addition to LIS acceptance testing, other tests are
                    available (e.g., additional cooperative acceptance testing,
                    automatic scheduled testing, cooperative scheduled testing,
                    manual scheduled testing, and non-scheduled testing) at the
                    applicable tariff rates.

     J.   Ordering

          1.   When ordering LIS, the ordering Party shall specify on the
               service order:  1) the type and number of interconnection
               facilities to terminate at the point of interconnection in the
               serving wire center; 2) the type of interoffice transport, (i.e.,
               direct trunk transport or tandem switched transport); 3) the peak
               busy hour CCS from the Pac-West end office; 4) the number of
               trunks to be provisioned at a local exchange office or tandem; 5)
               and any optional features (see form Appendix B).  When the
               ordering Party requests facilities, routing, or optional features
               different than those determined to be available, the Parties will
               work cooperatively in determining an acceptable configuration,
               based on available facilities, equipment and routing plans

          2.   When the ordering Party initially orders a DS3 interconnection
               facility, in conjunction with tandem switched transport to a
               tandem, or DS3 direct trunk transport facilities to a tandem or
               local exchange office, the provider will forward the appropriate
               DS1 facility record information necessary to identify the circuit
               facility assignment (CFA).  On subsequent orders utilizing
               existing DS3 interconnection facilities, or DS3 direct trunk
               transport facilities, the provider will assign the DS1 facility
               to the DS 3 interconnection facility or DS3 direct trunk
               transport facility, as directed by the ordering Party.

          3.   A joint planning meeting will precede Pac-West and USWC trunking
               orders.  These meetings will result in the transmittal of Access
               Service Requests (ASRs) to initiate order activity.  A Party
               requesting tandem interconnection will provide its best estimate
               of the traffic distribution to each end office subtending the
               tandem.

          4.   Service intervals and due dates for negotiated arrangements will
               be determined on an individual case basis.

                                                                         Page 15
<PAGE>

     K.   Billing Arrangements

          1.   USWC and Pac-West desire to submit separate bills, pursuant to
               their separate tariffs, to interexchange carriers for their
               respective portions of jointly provided switched access service.

               Based on the negotiated POI, the Parties will agree on a meet
               point percentage to enable the joint provisioning and billing of
               Switched Access Services to third parties in conformance with the
               Meet-Point Billing guidelines adopted by and contained in the
               Ordering and Billing Forum's MECAB and MECOD documents and
               referenced in USWC's Switched Access Tariffs. The Parties
               understand and agree that MPB arrangements are available and
               functional only to/from Interexchange Carriers who directly
               connect with the tandem(s) that Pac-West sub-tends in each LATA..

          2.   The parties will use reasonable efforts, individually and
               collectively, to maintain provisions in their respective federal
               and state access tariffs, and/or provisions within the National
               Exchange Carrier Association ("NECA") Tariff No. 4, or any
               successor tariff, sufficient to reflect this MPB arrangement,
               including MPB percentages.

          3.   As detailed in the MECAB document, Pac-West and USWC will
               exchange all information necessary to bill third parties for
               Switched Access Services traffic jointly handled by Pac-West and
               USWC via the meet point arrangement in a timely fashion.
               Information shall be exchanged in Exchange Message Record ("EMR")
               format (Bellcore Standard BR 010-200-010, as amended) on magnetic
               tape or via a mutually acceptable electronic file transfer
               protocol.  The Parties will exchange records pursuant to this
               paragraph without additional compensation.

          4.   The Parties will agree upon reasonable audit standards and other
               procedures as required to ensure billing accuracy.

          5.   Each company will bill the IXC's the appropriate rate elements in
               accordance with their respective interstate and intrastate
               tariffs, as follows:

               Rate Element                             Billing Company
               ------------                             ---------------
               Carrier Common Line                      Dial Tone Provider
               Local Switching                          Dial Tone Provider
               Interconnection Charge                   Dial Tone Provider
               Local Transport Termination              Based on negotiated BIP
               Local Transport Facility                 Based on negotiated BIP
                    (also called Tandem Transmission per mile)
               Tandem Switching                         Access Tandem Provider
               Entrance Facility                        Access Tandem Provider

                                                                         Page 16
<PAGE>

               6.   For originating 800/888 traffic routed to an access tandem,
                    the tandem provider will perform 800/888 database inquiry
                    and translation functions and bill the inquiry charge and
                    translation charge (if any) to the interexchange carrier
                    pursuant to tariff.



     L.   Mileage Measurement

          Where required, the mileage measurement for LIS facilities and trunks
          is determined in the same manner as the mileage measurement for
          Feature Group D Switched Access Service.

     M.   Construction Charges

          For issues related to construction charges, see Section XXIX of this
          Agreement.

                                                                         Page 17

VI.  INTERCONNECTION

     A.   Definition


          1.   Interconnection" is the linking of the USWC and Pac-West networks
               for the mutual exchange of traffic and for Pac-West access to
               unbundled network elements.  Interconnection does not include the
               transport and termination of traffic.  Interconnection is
               provided by virtual or physical collocation, entrance facilities
               or meet point arrangements.

          2.   USWC will provide interconnection at the line side of the local
               switch, the trunk side of the local switch, trunk interconnection
               points of the tandem switch, central office cross-connect points,
               and signaling transfer points necessary to exchange traffic and
               access call related databases.

     B.   Mid-span Meet POI

          1.   A Mid-Span Meet POI is a negotiated point of interface, limited
               to the interconnection of facilities between one Party's switch
               and the other Party's switch.  The actual physical point of
               interface and facilities used will be subject to negotiations
               between the Parties.  Each Party will be responsible for its
               portion of the build to the Mid-Span Meet POI, if the meet point
               arrangement is used exclusively for the exchange of local
               traffic.

          2.   If the Mid-Span Meet arrangement is to be used for access to
               unbundled network elements, Pac-West must pay the portion of the
               economic costs of the Mid-Span Meet arrangement used by Pac-West
               for access to unbundled network elements.

     C.   Collocation

          Interconnection may be accomplished through either virtual or physical
          collocation.  The terms and conditions under which collocation will be
          available are described in Section --- herein.

     D.   Entrance Facility

          Interconnection may be accomplished through the provision of an
          entrance facility.  An entrance facility extends from the serving wire
          center of the provider to the other party's switch location.  Entrance
          facilities may not extend beyond the area described by the provider's
          serving wire center.  The rates for entrance facilities are provided
          in Appendix A.

                                                                         Page 18
<PAGE>

     E.   Quality of Interconnection


          USWC will not, for the purpose of interconnection, provide to Pac-West
          less favorable terms and conditions than USWC provides itself or in a
          manner less efficient than it would impose on itself. The quality of
          interconnection will be at least equal to that of USWC. To the extent
          that Pac-West requests higher or lower quality interconnection,
          Pac-West agrees to use the New Interconnection/Unbundled Element
          Request procedure described in Section XXIII.

          Both Parties agree to manage their network switches in accordance with
          the Bellcore LSSGR.  The acceptable service levels for LIS and the
          criteria for applying protective controls will be administered in the
          same manner as the network management for Switched Access Service.

     F.   Points of Interface (POI)

          Upon the request for specific point to point routing, USWC will make
          available to Pac-West information indicating the location and
          technical characteristics of USWC's network facilities.  The following
          alternatives are negotiable:  (1) a DS1 or DS3 entrance facility,
          where facilities are available (where facilities are not available and
          USWC is required to build, see Section XXIX for issues relating to
          special construction charges); (2) Virtual Collocation; (3) Physical
          Collocation; and (4) negotiated Mid-Span Meet facilities.  Each Party
          is responsible for providing its own facilities up to the Mid-Span
          Meet POI.  The Parties will negotiate the facilities arrangement
          between their networks.

     G.   Trunking Requirements

          1.   USWC agrees to provide designed interconnection facilities that
               meet the same technical criteria and service standards, such as
               probability of blocking in peak hours and transmission standards,
               in accordance with industry standards.

          2.   Two-way trunk groups will be established wherever possible.
               Exceptions to this provision will be based on billing, signaling,
               and network requirements.  For example, (1) billing requirements
               - switched access vs. local traffic, (2) signaling requirements -
               MF vs. SS7, and (3) network requirements - directory assistance
               traffic to TOPS tandems.  The following is the current list of
               traffic types that require separate trunk groups, unless
               specifically otherwise stated in this Agreement.

               a.   IntraLATA toll and switched access trunks
               b.   EAS/local trunks
               c.   Directory Assistance trunks
               d.   911/E911 trunks
               e.   Operator services trunks

                                                                         Page 19
<PAGE>

               f.   Commercial Mobile Radio Service/Wireless traffic for which
                    Pac-West serves as the transit provider between the CMRS
                    provider and USWC.
               g.   (deleted)
               h.   (deleted)/3/
               i.   Meet Point Billing Trunks (for the joint provision of
                    switched access).


          3.   Trunk group connections will be made at a DS1 or multiple DS1
               level for exchange of EAS/local, intraLATA toll,
               wireless/Commercial Mobile Radio Service, and switched access
               traffic.  Ancillary service trunk groups will be made below a DS1
               level, as negotiated.

          4.   The Parties will provide Common Channel Signaling (CCS) to one
               another, where available, in conjunction with all Local/EAS Trunk
               Circuits.  All CCS signaling parameters will be provided
               including calling party number (CPN), originating line
               information (OLI) calling party category, charge number, etc.
               All privacy indicators will be honored.

          5.   Where CCS is not available, in-band multi-frequency (MF) wink
               start signaling will be provided.  When the Parties interconnect
               via CCS for jointly provided switched access service, the tandem
               provider will provide MF/CCS interworking as required for
               interconnection with interexchange carriers who use MF
               signalling.

          6.   The Parties will follow all Ordering and Billing Forum adopted
               standards pertaining to CIC/OZZ codes.

          7.   USWC will cooperate in the provision of TNS (Transit Network
               Selection) for the joint provision of switched access.

          8.   The Parties shall terminate local/EAS traffic exclusively on
               local/EAS trunk groups.  No local/EAS trunk groups shall be
               terminated on USWC's access tandems.

     H.   Service Interruptions.

          1. Standards and procedures for notification of trunk disconnects will
             be jointly developed by the Parties.  Neither Party shall be
             expected to maintain active status for a trunk disconnected by the
             other Party for an extended or indefinite period of time.
             Collectively, the Parties will use their best good faith efforts to
             complete and agree on such plan.

          2. The characteristics and methods of operation of any circuits,
             facilities or equipment of either Party connected with the
             services, facilities or equipment of the other Party pursuant to
             this Agreement shall not:  1) interfere with or impair service over
             any facilities of the other Party; its affiliated companies, or its
             connecting and concurring carriers involved in its services; 2)
             cause damage to their plant; 3) violate any applicable law or
             regulation regarding the invasion of privacy of any communications
             carried over the Party's facilities; or 4) create hazards to the
             employees of either Party or to the public.  Each of these
             requirements is hereinafter referred to as an "Impairment of
             Service".

          3. If either Party causes an Impairment of Service, as set forth in
             this Section, the Party whose network or service is being impaired
             (the "Impaired Party") shall promptly notify the Party causing the
             Impairment of Service (the "Impairing Party") of the nature and
             location of the problem.  They shall advise the Impairing Party
             that, unless promptly rectified, a temporary discontinuance of the
             use of any circuit, facility or equipment may be required.  The
             Impairing Party and the Impaired Party agree to work together to
             attempt to promptly resolve the Impairment of Service.  If the
             Impairing Party is unable to promptly remedy the Impairment of
             Service, the Impaired Party may temporarily discontinue use of the
             affected circuit, facility or equipment.

          4. Each Party shall be solely responsible, and bear the expense, for
             the overall design of its services. Each Party shall also be
             responsible for any redesign or rearrangement of its services that
             may be required because of changes in facilities, operations or
             procedures, minimum network protection criteria, and operating or
             maintenance characteristics of the facilities

          5. To facilitate trouble reporting and to coordinate the repair of the
             service provided by each Party to the other under this Agreement,
             each Party shall designate a Trouble Reporting Control Office
             (TRCO) for such service.

          6. Where new facilities, services and arrangements are installed, the
             TRCO shall ensure that continuity exists and take appropriate
             transmission measurements before advising the other Party that the
             new circuit is ready for service.

          7. Each Party shall furnish a trouble reporting telephone number for
             the designated TRCO.  This number shall give access to the location
             where facility records are normally located and where current
             status reports on any trouble reports are readily available.
             Alternative out-of-hours procedures shall be established to ensure
             access to a location that is staffed and has the authority to
             initiate corrective action.

          8. Before either Party reports a trouble condition, they shall use
             their best efforts to isolate the trouble to the other's
             facilities.

                                                                         Page 21
<PAGE>

            a)  In cases where a trouble condition affects a significant portion
                of the other's service, the Parties shall assign the same
                priority provided to other interconnecting carriers.

            b)  The Parties shall cooperate in isolating trouble conditions.


     I.   Interconnection Forecasting

          1.   The Parties agree that during the first year of interconnection,
               joint forecasting and planning meetings will take place no less
               frequently than once per quarter.

          2.   The Parties shall establish joint forecasting responsibilities
               for traffic utilization over trunk groups.  Intercompany forecast
               information must be provided by the Parties to each other four
               times a year.  The quarterly forecasts shall include forecasted
               requirements for each trunk group identified in Paragraph G(2) of
               this Section.  In addition, the forecast shall include, for
               tandem-switched traffic, the quantity of tandem-switched traffic
               forecasted for each subtending end office.  The Parties recognize
               that, to the extent historical traffic data can be shared between
               the Parties, the accuracy of the forecasts will improve.
               Forecasts shall be for a minimum of three (current and plus-1 and
               plus-2) years;

               a)   The use of Common Language Location Identifier (CLLI-MSG),
                    which are described in Bellcore documents BR 795-100-100 and
                    BR 795-400-100;

               b)   A description of major network projects anticipated for the
                    following six months that could affect the other Party.
                    Major network projects include trunking or network
                    rearrangements, shifts in anticipated traffic patterns, or
                    other activities that are reflected by a significant
                    increase or decrease in trunking demand for the following
                    forecasting period.  This planning will include the issues
                    of network capacity, forecasting and compensation
                    calculation, where appropriate.

          3.   If differences in quarterly forecasts of the Parties vary by more
               than 24 additional DS0 two-way trunks for each Local
               Interconnection Trunk Group, the Parties shall meet to reconcile
               the forecast to within 24 DS0 trunks.

          4.   If a trunk group is under 75 percent of centum call seconds (ccs)
               capacity on a monthly average basis for each month of any three
               month period, either Party may request to resize the trunk group,
               which resizing will not be unreasonably withheld.  If a resizing
               occurs, the trunk group shall not be left with less than 25
               percent excess capacity.  In all cases, grade of service
               objectives identified below shall be maintained.

                                                                         Page 22
<PAGE>

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


                                                                         Page 23

VII.  COLLOCATION


          1.   Collocation allows Pac-West to obtain dedicated space in a USWC
               wire center and to place equipment in such spaces to interconnect
               with the USWC network.  Pac-West may request collocation at other
               USWC locations pursuant to the NIUER Process or through
               additional interconnection negotiations under the Act.  USWC will
               provide the resources necessary for the operation and economical
               use of collocated equipment.  POIs for network interconnection
               can be established through virtual or physical collocation
               arrangements.

          2.   Collocation is offered for network interconnection between the
               Parties.  The collocated party may cross connect to other
               collocated parties via expanded interconnection channel
               terminations provided by USWC, provided that Pac-West's
               collocated equipment is used for interconnection with USWC or
               access to USWC's unbundled network elements.  Additional terms,
               conditions and rates apply in conjunction with subsequent call
               termination (e.g., call termination charges, tandem switching,
               tandem-switched transport, see Section V, Reciprocal Traffic
               Exchange.)

          3.   Except when Pac-West purchases USWC's unbundled network
               transmission elements, Pac-West will construct its own fiber
               optic cable to the USWC-designated point of interconnection.
               USWC will extend Pac-West's fiber optic cable from the POI to the
               cable vault within the wire center.  If necessary, USWC may bring
               the cable into compliance with USWC internal fire code standards
               and extend the cable to the collocated space.

          4.   Pac-West will be provided two points of entry into the USWC wire
               center only when there are at least two existing entry points for
               USWC cable and when there are vacant entrance ducts in both.
               USWC will promptly remove any unused cabling to free up entrance
               ducts when no other ducts are available.  Cable entry will be
               limited to fiber facilities.

          5.   Pac-West may collocate transmission equipment to terminate basic
               transmission facilities.  Pac-West may request collocation of
               other equipment pursuant to the NIUER Process or through
               additional interconnection negotiations under the Act.  CLEC must
               identify what equipment will be installed, to allow for USWC to
               use this information in engineering the power, floor loading,
               heat release, environmental particulant level, and HVAC.

          6.   Nothing in this part shall be construed to limit Pac-West's
               ability to obtain both virtual and physical collocation in a
               single location.

                                                                         Page 24

          8.   Maintenance Labor, Inspector Labor, Engineering Labor and
               Equipment Labor business hours are considered to be Monday
               through Friday, 8:00am to 5:00pm and after business hours are
               after 5:00pm and before 8:00am, Monday through Friday, all day
               Saturday, Sunday and holidays.

          9.   Pac-West will transfer possession of Pac-West's virtually
               collocated equipment to USWC via a no cost lease.  The sole
               purpose of the lease is to provide USWC with exclusive possessory
               rights to Pac-West's virtually collocated equipment.  Title to
               the Pac-West virtually collocated equipment shall not pass to
               USWC.

          10.  Installation and maintenance of Pac-West's virtually collocated
               equipment will be performed by USWC or a USWC authorized vendor.

          11.  Pac-West shall ensure that upon receipt of the Pac-West virtually
               collocated equipment by USWC, all warranties and access to
               ongoing technical support are passed through to USWC, all at Pac-
               West's expense.  The interconnector shall advise the manufacturer
               and seller of the virtually collocated equipment that it will be
               possessed, installed and maintained by USWC.

                                                                         Page 25

               Equipment Requirements TR-NWT-000063, Company wire center
               environmental and transmission standards and any statutory
               (local, state or federal) and/or regulatory requirements in
               effect at the time of equipment installation or that subsequently
               become effective. Pac-West shall provide USWC interface
               specifications (e.g., electrical, functional, physical and
               software) of Pac-West's virtually collocated equipment.

          13.  USWC may restrict the type of virtually collocated equipment.
               USWC will only permit basic transmission terminating equipment to
               be virtually collocated by Pac-West.  Pac-West may request
               collocation of other equipment pursuant to the NIUER Process or
               through additional interconnection negotiations under the Act..

          14.  Pac-West must specify all software options and associated plug-
               ins for its virtually collocated equipment.

          15.  Pac-West is responsible for purchasing and maintaining a supply
               of spares.  Upon failure of Pac-West's virtually collocated
               equipment, Pac-West is responsible for transportation and
               delivery of maintenance spares to USWC at the wire center housing
               the failed equipment.

C.  Physical Collocation

          1.   USWC shall provide to Pac-West Physical Collocation of equipment
               necessary for Interconnection or for access to unbundled Network
               Elements, except that USWC may provide for Virtual collocation if
               USWC demonstrates to the Commission that Physical Collocation is
               not practical for technical reasons or because of space
               limitations, as provided in Section 251(c)(6) of the Act.  USWC
               shall provide such Collocation for the purpose of Interconnection
               or access to unbundled Network Elements, except as otherwise
               mutually agreed to in writing by the Parties or as required by
               the FCC or the appropriate Commission subject to the rates, terms
               and conditions of this Agreement.

          2.   Where Pac-West is Virtually Collocated in a premises which was
               initially prepared for Virtual Collocation, Pac-West may elect to
               (i) retain its Virtual Collocation in that premises and expand
               that Virtual Collocation according to the rates, terms and
               conditions of this Agreement, or (ii) unless it is not practical
               for technical reasons or because of space limitations, convert
               its Virtual Collocation at such premises  to Physical
               Collocation, in which case Pac-West shall coordinate the
               construction and rearrangement with USWC of its equipment (IDLC
               and transmission) and circuits for which Pac-West shall pay USWC
               at applicable rates, and pursuant to the other terms and
               conditions in this Agreement.  In addition, all applicable
               Physical Collocation recurring charges shall apply.

                                                                         Page 26
<PAGE>

          3.   Pac-West will be allowed access to the POI on non-discriminatory
               terms.  Pac-West owns and is responsible for the installation,
               maintenance and repair of its transmission equipment located
               within the space rented from USWC.

          4.   Pac-West must use leased space promptly and may not warehouse
               space for later use or sublease to another provider.  Physical
               collocation is offered in wire centers on a space-available,
               first come, first-served basis.

          5.   The minimum standard leasable amount of floor space is 100 square
               feet.  Pac-West must efficiently use the leased space; no more
               than 50% of the floor space may be used for storage cabinets and
               work surfaces.  The Commission will be the final arbitrator in
               points of dispute between the parties.

          6.   Pac-West's leased floor space will be separated from other
               competitive providers and USWC space through cages or hard walls.
               Pac-West may elect to have USWC construct the cage, or choose
               from USWC approved contractors to construct the cage, meeting
               USWC's installation Technical Publication 77350.

                                                                         Page 27
<PAGE>

               f.   Work cooperatively with Pac-West in matters of joint testing
                    and maintenance.

          9.   Pac-West Responsibilities

               a.   Determine the type of enclosure for the physical space.

               b.   Where applicable, procure, install and maintain all fiber
                    optic facilities up to the USWC designated POI.

               c.   Install, maintain, repair and service all Pac-West's
                    equipment located in the leased physical space.

               d.   Ensure that all equipment installed by Pac-West complies
                    with Bellcore Network Equipment Building System Generic
                    Equipment requirements, USWC wire center environmental and
                    transmission standards, and any statutory (local, federal,
                    or state) or regulatory requirements in effect at the time
                    of equipment installation or that subsequently become
                    effective.

          10.  Once construction is complete for physical collocation and Pac-
               West has accepted its leased physical space, Pac-West may order
               its DS0, DS1, DS3 or other Expanded Interconnection Channel
               Terminations.

          11.  Pac-West may not extend dark fiber to Pac-West's leased physical
               space or connecting DS1/DS3 Channel Terminations to USWC dark
               fiber.

          12.  If, at any time, USWC determines that the equipment or the
               installation does not meet requirements, Pac-West will be
               responsible for the costs associated with the removal,
               modification to, or installation of the equipment to bring it
               into compliance.  If Pac-West fails to correct any non-compliance
               within fifteen (15) days of written notice of non-compliance,
               USWC may have the equipment removed or the condition corrected at
               Pac-West's expense.

          13.  If, during installation, USWC determines Pac-West activities or
               equipment are unsafe, non-standard or in violation of any
               applicable laws or regulations, USWC has the right to stop work
               until the situation is remedied.  If such conditions pose an
               immediate threat to the safety of USWC employees, interfere with
               the performance of USWC's service obligations, or pose an
               immediate threat to the physical integrity of the conduit system
               or the cable facilities, USWC may perform such work and/or take
               action as is necessary to correct the condition at Pac-West's
               expense.

               h.   Expanded Interconnection Channel Regeneration.  Required
                    when the distance from the leased physical space (for
                    physical collocation) or from the collocated equipment (for
                    virtual collocation) to the USWC network is of sufficient
                    length to require regeneration.

          2.   Physical Collocation Rate Elements

               The following rate elements apply only to physical collocation
               arrangements:

               a.   Floor Space Rental.  Provides the monthly rent for the
                    leased physical space, property taxes and base operating
                    cost without -48 Volt DC power.  Includes convenience 110
                    AC, 15 amp electrical outlets provided in accordance with
                    local codes and may not be used to power transmission
                    equipment or -48 Volt DC power generating equipment.  Also
                    includes maintenance for the leased space; provides for the
                    preventative maintenance (climate controls, filters, fire
                    and life systems and alarms, mechanical systems, standard
                    HVAC); biweekly housekeeping services (sweeping, spot
                    cleaning, trash removal) of  the USWC wire center areas
                    surrounding the leased physical space  and general repair
                    and maintenance.

               b.   Enclosure Buildout.  The Enclosure Buildout element, either
                    Cage or, at the Pac-West's option, Hardwall, includes the
                    material and labor to construct the enclosure specified by
                    Pac-West or Pac-West may choose from USWC approved
                    contractors to construct the cage, meeting USWC's
                    installation Technical Publication 77350.  It includes the

                    enclosure).  Also provides for humidification, if required.

               c.   Pricing for the above physical collocation rate elements
                    will be provided on an individual basis due to the
                    uniqueness of Pac-West's requirements, central office
                    structure and arrangements.

                                                                         Page 30
<PAGE>

          3.  Virtual Collocation Rate Elements

              The following rate elements apply uniquely to virtual collocation:

               a.   Maintenance Labor -- Provides for the labor necessary for
                    repair of out of service and/or service-affecting conditions
                    and preventative maintenance of the Pac-West virtually
                    collocated equipment.  Pac-West is responsible for ordering
                    maintenance spares.  USWC will perform maintenance and/or
                    repair work upon receipt of the replacement maintenance
                    spare and/or equipment for Pac-West.  A call-out of a
                    maintenance technician after business hours is subject to a
                    minimum charge as specified above.

               b.   Training Labor -- Provides for the billing of vendor-
                    provided training for USWC personnel on a metropolitan
                    service area basis, necessary for Pac-West virtually
                    collocated equipment which is different from USWC provided
                    equipment.  USWC will require three USWC employees to be
                    trained per metropolitan service area in which the Pac-West
                    virtually collocated equipment is located.  If, by an act of
                    USWC, trained employees are relocated, retired, or are no
                    longer available, USWC will not require Pac-West to provide
                    training for additional USWC employees for the same
                    virtually collocated equipment in the same metropolitan
                    area.  The amount of training billed to Pac-West will be
                    reduced by half, should a second collocator in the same
                    metropolitan area select the same virtually collocated
                    equipment as Pac-West.

               c.   Equipment Bay -- Provides mounting space for the Pac-West
                    virtually collocated equipment.  Each bay includes the 7
                    foot bay, its installation, all necessary environmental
                    supports.  Mounting space on the bay, including space for
                    the fuse panel and air gaps necessary for heat dissipation
                    is limited to 78 inches.  The monthly rate is applied per
                    shelf.

               d.   Engineering Labor -- Provides the planning and engineering
                    of the Pac-West virtually collocated equipment at the time
                    of installation, change or removal.

               e.   Installation Labor -- Provides for the installation, change
                    or removal of the Pac-West virtually collocated equipment.

E.  Collocation Installation Intervals

          The following intervals are common to both virtual and physical
          collocation:

          1.   Acknowledgment of Floor Space Availability.  Within fifteen days
               of the receipt by USWC from Pac-West of a Request for Collocation
               and an associated Quote Preparation Fee, USWC will notify Pac-
               West whether
                                                                         Page 31

<PAGE>

               the sufficient floor space is available to accommodate Pac-West's
               request.

          2.   Quote Preparation.  Within twenty-five business days of the
               receipt by USWC from Pac-West of a Request for Collocation and an
               associated Quote Preparation Fee, USWC provide Pac-West with a
               written quotation containing all nonrecurring charges for the
               requested collocation arrangement.

          3.   Quote Acceptance. Within thirty days of the receipt by Pac-West
               of the USWC quotation, Pac-West will accept the USWC proposed
               quotation.  Acceptance shall require payment to USWC of fifty
               percent of the non-recurring charges provided on the quotation.

          4.   Completion of Cage Construction (physical collocation only).
               Within 90 days of the acceptance of the quotation by Pac-West,
               the construction of the necessary cage/hardwall enclosure shall
               be completed.  At this time, the leased floor space will be
               available to Pac-West for installation of its collocated
               equipment.

          5.   Completion of Collocated Equipment Installation (virtual
               collocation only) -- USWC shall complete the installation of Pac-
               West's collocated equipment within 90 days of USWC's receipt of
               Pac-West's collocated equipment.  The installation of line cards
               and other minor modifications shall be performed by USWC on
               intervals equivalent to those that USWC applies to itself, but in
               no instance shall any such interval exceed 90 days.

                                                                         Page 32

VIII.  INTERIM NUMBER PORTABILITY


     A.   General Terms

          1. The Parties shall provide Number Portability on a reciprocal basis
             to each other to the extent technically feasible, and in accordance
             with rules and regulations as from time to time prescribed by the
             FCC and/or the Commission.

          2. Until Number Portability is implemented by the industry pursuant to
             regulations issued by the FCC or the Commission, the Parties agree
             to provide Interim Telecommunications Number Portability ("INP") to
             each other through remote call forwarding, direct inward dialing
             and NXX migration.

          3. Once permanent number portability is implemented pursuant to FCC or
             Commission regulation, either Party may withdraw, at any time and
             at its sole discretion, its INP offerings, subject to advance
             notice to the other Party and coordination to allow the seamless
             and transparent conversion of INP customer numbers to permanent
             number portability.  Upon implementation of permanent number
             portability pursuant to FCC regulations, both parties agree to
             conform and provide such permanent number portability.

          4. USWC will update its Line Information Database ("LIDB") listings
             for retained numbers, and restrict or cancel calling cards
             associated with these forwarded numbers as directed by Pac-West.
             LIDB updates shall be completed by the Parties on the same business
             day each INP arrangement is activated.

          5. Upon request, USWC shall provide to Pac-West INP via Direct Inward
             Dial Trunks pursuant to applicable tariffs.

          6. Where either party has activated an entire NXX for a single
             customer, or activated a substantial portion of an NXX for a single
             customer with the remaining numbers in that NXX either reserved for
             future use or otherwise unused, if such customer 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 be
             accomplished with appropriate coordination between the Parties and
             subject to appropriate industry lead-times for movement of NXXs
             from one switch to another.  Other applications of NXX migration
             will be discussed by the Parties as circumstances arise.

     B.   Description Of Service

          1. Interim Number Portability Service ("INP") is a service arrangement
             that can be provided by USWC to Pac-West or by Pac-West to USWC.
             For the purposes of this section, the Party porting traffic to the
             other Party shall be

                                                                         Page 33
<PAGE>

             referred to as the "INP Provider" and the Party receiving INP
             traffic for termination shall be referred to as the "INP
             Requestor".

          2. INP applies to those situations where an end-user customer elects
             to transfer service from the INP Provider to the INP Requestor and
             they also wish to retain their existing telephone number.  INP
             consists of INP Provider's provision to the INP Requestor the
             capability to route calls placed to telephone numbers assigned to
             the INP Provider's switches to the INP Requestor's switches.  INP
             is available only for working telephone numbers assigned to the INP
             Provider's customers who request to transfer to the INP Requestor's
             service

          3. INP is available as INP-Remote Call Forwarding ("INP-RCF")
             permitting a call to a INP Provider's assigned telephone number to
             be translated to the INP Requestor's dialable local number.  INP
             Requestor may terminate the call as desired.  Additional capacity
             for simultaneous call forwarding is available where technically
             feasible.  The INP Requestor will need to specify the number of
             simultaneous calls to be forwarded for each number ported.

          4. INP is subject to the following restrictions:

                    i.   An INP telephone number may be assigned by INP
                         Requestor only to the Requestor's customers located
                         within the INP Provider's local calling area and toll
                         rating area that is associated with the NXX of the
                         portable number.

                    ii.  INP is applicable only if the INP Requestor is engaged
                         in a reciprocal traffic exchange arrangement with the
                         INP Provider.

                    iii. Only the existing, INP Provider assigned end-user
                         telephone number may be used as a ported number for
                         INP.

                    iv.  INP will not be provided by the INP Provider for
                         customers whose accounts are in arrears and who elect
                         to make a change of service provider unless and until
                         the following conditions are met:

                         -    Full payment for the account (including directory
                              advertising charges associated with the customer's
                              telephone number) is made by customer or INP
                              Requestor agrees to make full payment on behalf of
                              customer.

                         -    INP Provider is notified in advance of the change
                              in service provider and a Change of Responsibility
                              form is issued.

                         -    INP Provider accepts the transfer of
                              responsibility.

                                                                         Page 34
<PAGE>

                    v.   INP services shall not be re-sold, shared or assigned
                         by either party to another LEC or CLEC.

                    vi.  INP is not offered for NXX Codes 555, 976, 960 and coin
                         telephones, and Service Access Codes (i.e. 500, 700,
                         800/888, 900).  INP is not available for FGA seven-
                         digit numbers, including foreign exchange (FEX), FX and
                         FX/ONAL and foreign Central Office Service.
                         Furthermore, INP numbers may not be used for mass
                         calling events.

                    vii. The ported telephone number will be returned to the
                         originating company (or to the common pool of telephone
                         numbers upon implementation of permanent number
                         portability) when the ported service is disconnected.
                         The company purchasing a ported number may not retain
                         it and reassign it to another customer.  The normal
                         intercept announcement will be provided by the INP
                         Provider for the period of time until the telephone
                         number is reassigned by the Provider.

          3.   Ordering and Maintenance

               a.   The INP Requestor is responsible for all dealings with and
                    on behalf of its end users, including all end user account
                    activity, e.g. end user queries and complaints.

               b.   Each party is responsible for obtaining a Letter of
                    Authorization (LOA) from its end users who requests a
                    transfer of the end user's telephone number from the other
                    party.

               c.   The INP Provider will work cooperatively with the Requestor
                    to ensure a smooth customer transition and to avoid
                    unnecessary duplication of other facilities (e.g., unbundled
                    loops). The Parties will cooperate to develop intercompany
                    procedures to implement the requirements of this paragraph.

               d.   If an end user requests transfer of service from the INP
                    Requestor back to the INP Provider, the Provider may rely on
                    that end user request to institute cancellation of the INP
                    service.  The INP Provider will provide at least 48 hours
                    notice to the INP Requestor of the cancellation of INP
                    service, and will work cooperatively with the Requestor to
                    ensure a smooth customer transition and to avoid unnecessary
                    duplication of other facilities (e.g., unbundled loops).
                    The Parties will cooperate to develop intercompany
                    procedures to implement the requirements of this paragraph.

                                                                         Page 35
<PAGE>

               e.   Certain features are not available on calls passed through
                    INP service.

               f.   The Requestor's designated INP switch must return answer and
                    disconnect supervision to the INP Provider's switch.

               g.   The Requestor will provide to the E911 database provider the
                    network telephone number that the Requestor assigned to the
                    Provider-assigned, ported telephone number.  Updates to and
                    maintenance of the INP information to the E911 database are
                    the responsibility of the INP Requestor.

               h.   The INP Requestor will submit to the INP Provider a
                    disconnect order for each ported number that is relinquished
                    by the Requestor's end users.

          4.   Cost Recovery


               The parties agree that, for the purposes of this agreement that
               the following cost structure is an acceptable measure of the
               costs incurred by the INP Provider.

               a.   Number Ported -- This cost is incurred per number ported,
                    per month.  Should the INP Requestor provide the transport
                    from the Provider's end office to the Requestor's end office
                    switch, a lower cost is incurred.  This cost represents a
                    single call path from the Provider's end office switch to
                    the Requestor for the portable number.

               b.   Additional Call Path -- This cost is incurred per
                    additional call path per month added to a particular ported
                    telephone number.  Should the INP Requestor provide the
                    transport from the Provider's end office to the Requestor's
                    end office switch, a lower cost is incurred.

               c.   Service Establishment -- Per Switch.  This non-recurring
                    cost is incurred for each INP Provider's end office switch
                    that is equipped to provide INP to the INP Requestor.

               d.   Service Establishment -- Per Number -- This non-recurring
                    cost is for each telephone number equipped with INP.

               e.   The parties agree that Appendix A reasonably identifies the
                    above costs.

               f.   Solely for the purposes of this arbitrated agreement between
                    USWC and Pac-West, these two parties agree to assign between

                                                                         Page 36
<PAGE>

                    themselves, on an interim basis, interim number portability
                    costs on the basis of active local numbers, recognizing that
                    such assignment necessarily excludes recovery from other
                    industry participants.  Each party is free to advocate the
                    assignment of interim number portability costs to other
                    industry participants as part of the appropriate industry-
                    wide cost recovery method./4/

               g.   The parties shall, each quarter, exchange the confidential
                    data necessary to implement the above pro-rata assignment of
                    interim number portability costs.

               h.   The INP Provider will, when using RCF, send the original
                    ("ported") number over the interconnection arrangements as
                    the calling party number using the signaling protocol
                    applicable to the arrangements.  The INP Requestor will
                    capture and measure the number of minutes of INP incoming
                    traffic.  USWC will provide (and update quarterly)
                    percentage distributions of all terminating traffic in the
                    LATA by jurisdictional nature of the traffic:  a)  local;
                    b)intrastate, intraLATA switched access; c) intrastate,
                    interLATA switched access; d) interstate, intraLATA switched
                    access; e) interstate, interLATA switched access..  Separate
                    residence and business percentage distributions will be
                    provided, to the extent possible.  The Parties agree to work
                    cooperatively to develop and exchange the data required to
                    implement this paragraph.  The appropriate percentage will
                    be applied to the number of minutes of INP traffic in each
                    category to determine the number of minutes eligible for
                    additional "pass through" switched access compensation.
                    Pass through switched access compensation will be paid at
                    the following rates:


                    For all intra-LATA toll and inter-LATA minutes delivered
                    over INP, USWC will pay, in lieu of reciprocal compensation,
                    all terminating switched access elements otherwise due the
                    terminating office provider, including:/5/

                              end office switching;
                              IC (interconnection charge);
                              CCLC; and
                              appropriate portion of tandem switched transport.

               i.   Rates are contained in Appendix A.

IX.  DIALING PARITY

The Parties shall provide Dialing Parity to each other as required under Section
251(b)(3) of the Act.  This Agreement does not impact either Party's ability to
default intraLATA toll via a specific dialing pattern until otherwise required
by the Act.

                                                                         Page 38

X.   ACCESS TO TELEPHONE NUMBERS

     1.   Number Resources Arrangements.

               a.   Nothing in this Agreement shall be construed in any manner
                    to limit or otherwise adversely impact either Party's right
                    to the request and assignment of any NANP number resources
                    including, but not limited to, central office (NXX) codes
                    pursuant to the Central Office Code Assignment Guidelines
                    (last published by the Industry Numbering Committee ("INC")
                    as INC 95-0407-008, Revision 4/19/96, formerly ICCF 93-0729-
                    010).  NXXs, and the initial points of interface for
                    interconnection between the Parties' networks, will be
                    included in Addenda to this Agreement.

               b.   To the extent USWC serves as Central Office Code
                    Administrator for a given region, USWC will support all Pac-
                    West requests related to central office (NXX) code
                    administration and assignments in the manner required and
                    consistent with the Central Office Code Assignment
                    Guidelines.

               c.   The parties shall provide local dialing parity to each other
                    as required under Section 251(b)(3) of the Act.

               d.   The Parties will comply with code administration
                    requirements as prescribed by the Federal Communications
                    Commission, the Commission, and accepted industry
                    guidelines.

               e.   It shall be the responsibility of each Party to program and
                    update its own switches and network systems pursuant to the
                    Local Exchange Routing Guide (LERG) guidelines to recognize
                    and route traffic to the other Party's assigned NXX codes at
                    all times.  Neither Party shall impose any fees or charges
                    whatsoever on the other Party for such activities.  The
                    Parties will cooperate to establish procedures to ensure the
                    timely activation of NXX assignments in their respective
                    networks.

               f.   Each Party shall be responsible for notifying its customers
                    of any changes in numbering or dialing arrangements to
                    include changes such as the introduction of new NPAs or new
                    NXX codes.

               g.   Until an impartial entity is appointed to administer
                    telecommunications numbering and to make such numbers
                    available on an equitable basis, USWC will assign NXX codes
                    to Pac-West  in accordance with national guidelines at no
                    charge.

                                                                         Page 39
<PAGE>

               h.   Each Party is responsible for administering NXX codes
                    assigned to it.  Each Party is responsible for obtaining
                    Local Exchange Routing Guide ("LERG") listings of CLLI codes
                    assigned to its switches.  Each party shall use the LERG
                    published by Bellcore or its successor for obtaining routing
                    information and shall provide all required information to
                    Bellcore for maintaining the LERG in a timely manner.

                                                                         Page 40

XI.  CALL COMPLETION FROM USWC OPERATORS

USWC Operators will provide operator call completion and call completion and
rating information and like assistance to any end user customer reaching USWC
Operators (including information for calls to Pac-West' NXXs) in the same manner
as they provide such services for end user customers served by USWC NXXs and for
calls involving only USWC NXXs.

                                                                         Page 41
<PAGE>

XII. BUSY LINE VERIFY/INTERRUPT

  A) Busy Line Verification ("BLV") is performed when one Party's Customer
     requests assistance from the operator bureau to determine if the called
     line is in use, however, the operator bureau will not complete the call for
     the Customer initiating the BLV inquiry.  Only one BLV attempt will be made
     per Customer operator bureau call, and a charge shall apply whether or not
     the called party releases the line.

  B) Busy Line Verification Interrupt ("BLVI") is performed when one Party's
     operator bureau interrupts a telephone call in progress after BLV has
     occurred.  The operator bureau will interrupt the busy line and inform the
     called party that there is a call waiting.  The operator bureau will only
     interrupt the call and will not complete the telephone call of the Customer
     initiating the BLVI request.  The operator bureau will make only one BLVI
     attempt per Customer operator telephone call and the applicable charge
     applies whether or not the called party releases the line.

  C) The rate for Busy Line Verify shall be $.72 per call, and for Busy Line
     Verify and Interrupt, $.87 per call.

  D) 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.

  E) Each Party shall route BLV/BLVI Traffic inquiries over separate direct
     trunks (and not the Local/IntraLATA Trunks) established between the
     Parties' respective operator bureaus.  Unless otherwise mutually agreed,
     the Parties shall configure BLV/BLVI trunks over the Interconnection
     architecture defined in Section VI, Interconnection, consistent with the
     Joint Grooming Plan.  Each Party shall compensate the other Party for
     BLV/BLVI Traffic as set forth above.

                                                                         Page 42

XIII.  TOLL AND ASSISTANCE OPERATOR SERVICES

          1.   Description of Service.

               Toll and Assistance refers to functions customers associate with
               the "O" operator.  Subject to availability and capacity, access
               may be provided via operator services trunks purchased from USWC
               or provided by Pac-West via collocation arrangements to route
               calls to Pac-West's platform.

          2.   Functions include:

               a.   O-Coin, Automatic Coin Telephone Service (ACTS) - these
                    functions complete coin calls, collect coins and provide
                    coin rates.

               b.   Alternate Billing Services (ABS or O+ dialing):  Bill to
                    third party, Collect and Mechanized Credit Card System
                    (MCCS).

               c.   O- or operator assistance which provides general assistance
                    such as dialing instruction and assistance, rate quotes,
                    emergency call completion and providing credit.

               d.   Automated Branding - ability to announce the carrier's name
                    to the customer during the introduction of the call.

               e.   Rating Services - operators have access to tables that are
                    populated with all toll rates used by the operator switch.

          3.   Pricing for Toll and Assistance Operator Services shall be
               determined on a case-by-case basis, upon request.

          4.   Interconnection to the USWC Toll and Assistance Operator Services
               from an end office to USWC T/A is technically feasible at three
               distinct points on the trunk side of the switch.  The first
               connection point is an operator services trunk connected directly
               to the T/A host switch.  The second connection point is an
               operator services trunk connected directly to a remote T/A
               switch.  The third connection point is an operator services trunk
               connected to a remote access tandem with operator concentration
               capabilities.

          5.   Trunk provisioning and facility ownership will follow the
               guidelines recommended by the Trunking and Routing, IOF and
               Switch sub-teams.  All trunk interconnections will be digital.

          6.   Toll and Assistance interconnection will require an operator
               services type trunk between the end office and the
               interconnection point on the USWC switch.

          7.   Connecting a position to the host system requires two circuits
               (one voice and one data) per position on a T1 facility.

                                                                         Page 43
<PAGE>

          8.   The technical requirements of operator services type trunks and
               the circuits to connect the positions to the host are covered in
               the OSSGR under Section 6 (Signaling) and Section 10 (System
               Interfaces) in general requirements form.

                                                                         Page 44

XIV. DIRECTORY ASSISTANCE

  A) USWC agrees to (1) provide to Pac-West' operators on line access to USWC's
     directory assistance database; (2) provide to Pac-West unbranded directory
     assistance service (3) provide to Pac-West directory assistance service
     under Pac-West brand (where technically feasible); (4) allow Pac-West or an
     Pac-West designated operator bureau to license USWC's directory assistance
     database for use in providing competitive directory assistance services;
     and (5) in conjunction with (2) or (3) above, provide caller-optional
     directory assistance call completion service which is comparable in every
     way to the directory assistance call completion service USWC makes
     available to its own users and to provide caller name and number.

  B) The price for directory assistance, provided pursuant to this Agreement,
     shall be 34 cents per call.  As an alternative, the Parties may obtain
     directory assistance service pursuant to effective tariffs.

  C) The price for directory call completion services shall be 35 cents  per
     call, pending the completion of an approved TELRIC cost study.  Additional
     charges, for USWC intraLATA toll services, also apply for completed
     intraLATA toll calls.  Long distance service shall be available pursuant to
     the wholesale discount provided in Section XXX, Resale, herein.  Call
     completion service is an optional service.  Pac-West may, at its option,
     request USWC to not provide call completion services to Pac-West customers.



      A.  Scope.

          1.   Listings Service ("Listings") consists of USWC placing the names,
               addresses and telephone numbers of Pac-West's end users in USWC's
               listing database, based on end user information provided to USWC
               by Pac-West.  USWC is authorized to use Listings in Directory
               Assistance (DA) and as noted in paragraph 4, below.

          2.   Pac-West will provide in standard, mechanized format, and USWC
               will accept at no charge, one primary listing for each main
               telephone number belonging to Pac-West's end user customers.
               Primary listings are as defined for USWC end users in USWC's
               general exchange tariffs.  Pac-West will be charged for premium
               listings, e.g., additional, foreign, cross reference,
               informational, etc., at USWC's general exchange listing tariff
               rates.  Pac-West utilizing Remote Call Forwarding for local
               number portability can list only one number without charge -
               either the end customer's original telephone number or the Pac-
               West-assigned number.  The standard discounted rate for an
               additional listing applies to the other number.

          3.   USWC will furnish Pac-West the Listings format specifications.
               Pac-West may supply a maximum of one batch file daily, containing
               only Listings that completed on or prior to the transmission
               date.  USWC cannot

                                                                         Page 45
<PAGE>

               accept Listings with advance completion dates. Large volume
               activity (e.g., 100 or more listings) on a caption set is
               considered a project that requires coordination between Pac-West
               and USWC to determine time frames.

          4.   Pac-West grants USWC a non-exclusive license to incorporate
               Listings information into its directory assistance database.
               Pac-West hereby selects one of two options for USWC's use of
               Listings and dissemination of Listings to third parties.

                    EITHER:

               a.   Treat the same as USWC's end user listings - No prior
                    authorization is needed for USWC to release Listings to
                    directory publishers or other third parties.  USWC will
                    incorporate Listings information in all existing and future
                    directory assistance applications developed by USWC.  Pac-
                    West authorizes USWC to sell and otherwise make Listings
                    available to directory publishers.  USWC shall be entitled
                    to retain all revenue associated with any such sales.
                    Listings shall not be provided or sold in such a manner as
                    to segregate end users by carrier.

                    OR:
               b.   Restrict to USWC's directory assistance -- Prior
                    authorization required by Pac-West for all other uses.  Pac-
                    West makes its own, separate agreements with USWC, third
                    parties and directory publishers for all uses of its
                    Listings beyond DA.  USWC will sell Listings to directory
                    publishers (including USWC's publisher affiliate), other
                    third parties and USWC products only after the third party
                    presents proof of Pac-West's authorization.  USWC shall be
                    entitled to retain all revenue associated with any such
                    sales.  Listings shall not be provided or sold in such a
                    manner as to segregate end users by carrier.

          5.   To the extent that state tariffs limit USWC's liability with
               regard to Listings, the applicable state tariff(s) is
               incorporated herein and supersedes Section XXXIV(U), "Limitation
               of Liability", of this Agreement with respect to Listings only.

      B.  USWC Responsibilities

          1.   USWC is responsible for maintaining Listings, including entering,
               changing, correcting, rearranging and removing Listings in
               accordance with Pac-West orders.  USWC will take reasonable steps
               in accordance with industry practices to accommodate non-
               published and non-listed Listings provided that Pac-West has
               supplied USWC the necessary privacy indicators on such Listings.

                                                                         Page 46
<PAGE>

          2.   USWC will include Pac-West Listings in USWC's Directory
               Assistance service to ensure that callers to USWC's Directory
               Assistance service have non-discriminatory access to Pac-West's
               Listings.

          3.   USWC will incorporate Pac-West Listings provided to USWC in the
               white pages directory published on USWC's behalf.

      C.  Pac-West Responsibilities

          1.   Pac-West agrees to provide to USWC its end user names, addresses
               and telephone numbers in a standard mechanized format, as
               specified by USWC.

          2.   Pac-West will supply its ACNA/CIC or CLCC/OCN, as appropriate,
               with each order to provide USWC the means of identifying Listings
               ownership.

          3.   Pac-West represents and warrants the end user information
               provided to USWC is accurate and correct.  Pac-West further
               represents and warrants that it has reviewed all Listings
               provided to USWC, including end user requested restrictions on
               use such as non-published and non-listed.  Pac-West shall be
               solely responsible for knowing and adhering to state laws or
               rulings regarding Listings (e.g., no solicitation requirements in
               the states of Arizona and Oregon, privacy requirements in
               Colorado), and for supplying USWC with the applicable Listing
               information.

          4.   Pac-West is responsible for all dealings with, and on behalf of,
               Pac-West's end users, including:

               a.   All end user account activity, e.g. end user queries and
                    complaints.

               b.   All account maintenance activity, e.g., additions, changes,
                    issuance of orders for Listings to USWC.

               c.   Determining privacy requirements and accurately coding the
                    privacy indicators for Pac-West's end user information.  If
                    end user information provided by Pac-West to USWC does not
                    contain a privacy indicator, no privacy restrictions will
                    apply.

               d.   Any additional services requested by Pac-West's end users.

     D.   The terms contained in this Section refer specifically to the
          provision of Listings from Pac-West to USWC.  The Parties acknowledge
          that the Telecommunications Act of 1996 imposes reciprocal obligations
          on incumbent and new entrant Local Exchange providers with respect to
          directory assistance listings and white pages listings.  As a result,
          the Parties agree that the terms in this Section are reciprocal and
          also include the provision of Listings from USWC to Pac-West, in the
          event that Pac-West provides its own directory assistance service or
          publishes its own white pages directory.

                                                                         Page 47

XVI. U S WEST DIRECT ISSUES

     USWC and Pac-West agree that certain issues, such as yellow page
advertising, directory distribution, access to call guide pages, yellow page
listings, will be the subject of negotiations between Pac-West and directory
publishers, including U S WEST Direct.  USWC acknowledges that Pac-West may
request USWC to facilitate discussions between Pac-West and U S WEST Direct.

                                                                         Page 48

XVII.  ACCESS TO POLES, DUCTS, CONDUITS, AND RIGHTS OF WAY

Each Party shall provide the other Party access to its poles, ducts, rights-of-
way and conduits it controls on terms, conditions and prices comparable to those
offered to any other entity pursuant to each party's applicable tariffs and/or
standard agreements.

                                                                         Page 49
<PAGE>

XVIII.  ACCESS TO DATABASES

In accordance with Section 271 of the Act, USWC shall provide Pac-West with
interfaces to access USWC's databases and associated signaling necessary for the
routing and completion of Pac-West' traffic.  Except where otherwise specified,
access to such databases, and the appropriate interfaces, shall be made
available to Pac-West via a Network Interconnection and Unbundled Element
Request.

                                                                         Page 50

affect the inter-operability of its network with the other Party, the Party
making the change shall provide advance notice of such change to the other Party
in accordance with the applicable FCC regulations.

                                                                         Page 51

                    viii. The Parties will cooperate in the routing of 911
                          traffic in those instances where the ALI/ANI

                          instances where the Pac-West customer dials "O"
                          instead of "911".

               c.   If a third party; i.e., LEC, is the primary service provider
                    to a county, Pac-West will negotiate separately with such
                    third party with regard to the provision of 911 service to
                    the county.  All relations between such third party and Pac-
                    West are totally separate from this Agreement and USWC makes
                    no representations on behalf of the third party.

                    incurred in the provision of E-911 services.

          2.   Performance Criteria.  E-911 Data Base accuracy shall be as set
               forth below:

               a.   Accuracy of ALI (Automatic Location Identification) data
                    will be measured jointly by the PSAPs (Public Safety
                    Answering Points) and USWC in a format supplied by USWC.
                    The reports shall be forwarded to Pac-West by USWC when
                    relevant and will indicate incidents when incorrect or no
                    ALI data is displayed.

               b.   Each discrepancy report will be jointly researched by USWC
                    and Pac-West.  Corrective action will be taken immediately
                    by the responsible party.

                                                                         Page 53
<PAGE>

               c.   Each party will be responsible for the accuracy of its
                    customer records.  Each party specifically agrees to
                    indemnify and hold harmless the other party from any claims,
                    damages, or suits related to the accuracy of customer data
                    provided for inclusion in the E-911 Data Base.

               d.   The additional parameters by which the Parties will utilize
                    the 911 or E-911 database will be the subject of further
                    discussion between the parties.

                                                                         Page 54
<PAGE>

XXI. REFERRAL ANNOUNCEMENT

     When an end user customer changes from USWC to Pac-West, or from Pac-West
     to USWC, and does not retain their original telephone number, the Party
     formerly providing service to the end user will provide a transfer of
     service announcement on the abandoned telephone number.  Each Party will
     provide this referral service consistent with its tariff.  This
     announcement will provide details on the new number that must be dialed to
     reach this customer.

                                                                         Page 55
<PAGE>

XXII.  COORDINATED REPAIR CALLS

          1.   Pac-West and USWC will employ the following procedures for
               handling misdirected repair calls;

               a.   Pac-West and USWC will provide their respective customers
                    with the correct telephone numbers to call for access to
                    their respective repair bureaus.

               b.   Customers of Pac-West shall be instructed to report all
                    cases of trouble to Pac-West.  Customers of USWC shall be
                    instructed to report all cases of trouble to USWC.

               c.   To the extent the correct provider can be determined,
                    misdirected repair calls will be referred to the proper
                    provider of Basic Exchange Telecommunications Service.

               d.   Pac-West and USWC will provide their respective repair
                    contact numbers to one another on a reciprocal basis.

               e.   In responding to repair calls, neither Party shall make
                    disparaging remarks about each other, nor shall they use
                    these repair calls as the basis for internal referrals or to
                    solicit customers to market services.  Either Party may
                    respond with accurate information in answering customer
                    questions.

                                                                         Page 56

XXIII.  NETWORK INTERCONNECTION AND UNBUNDLED ELEMENT REQUEST

A.   Any request for interconnection or access to an unbundled Network Element
     that is not already available as described herein shall be treated as a
     Network Interconnection and Unbundled Element Request (NIUER).  USWC shall
     use the NIUER Process to determine technical feasibility of the requested
     interconnection or Network Elements and, for those items found to be
     feasible, to provide the terms and timetable for providing the requested
     items.

B.   A NIUER shall be submitted in writing and shall, at a minimum, include: (a)
     a technical description of each requested Network Element or
     interconnection; (b) the desired interface specification; (c) each
     requested type of interconnection or access; (d) a statement that the
     interconnection or Network Element will be used to provide a
     telecommunications service; and (e) the quantity requested.

C.   Within 15 business days of its receipt, USWC shall acknowledge receipt of
     the NIUER and in such acknowledgment advise Pac-West of any missing
     information, if any, necessary to process the NIUER.  Thereafter, USWC
     shall promptly advise Pac-West of the need for any additional information
     that will facilitate the analysis of the NIUER.

D.   Within 30 calendar days of its receipt of the NIUER and all information
     necessary to process it, USWC shall provide to Pac-West a preliminary
     analysis of the NIUER.  The preliminary analysis shall specify: (a) USWC's
     conclusions as to whether or not the requested interconnection or access to
     an unbundled Network Element is technically feasible; and (b) any
     objections to qualification of the requested Network Element or
     interconnection under the Act.

         1.    If USWC determines during the 30 day period that a NIUER is not
               technically feasible or that the NIUER otherwise does not qualify
               as a Network Element of interconnection that is required to be
               provided under the Act, USWC shall advise Pac-West as soon as
               reasonably possible of that fact, and USWC shall promptly, but in
               no case later than ten days after making such a determination,
               provide a written report setting forth the basis for its
               conclusion.

         2.    If USWC determines during the thirty day period that the NIUER is
               technically feasible and otherwise qualifies under the Act, it
               shall notify Pac-West in writing of such determination within ten
               days.

         3.    As soon as feasible, but in any case within 90 days after USWC
               notifies Pac-West that the NIUER is technically feasible, USWC
               shall provide to Pac-West a NIUER quote which will include, at a
               minimum, a description of each interconnection and Network
               Element, the quantity to be provided, any interface
               specifications, and the applicable rates (recurring and
               nonrecurring) including the separately stated amortized
               development costs of the interconnection or the network elements
               and any minimum volume and term commitments required to achieve
               amortization of development costs.  An initial payment for
               development cost is

                                                                         Page 57
<PAGE>

               appropriate only where Pac-West is the only conceivable customer
               or where requested quantity is insufficient to provide
               amortization.

E.   If USWC has indicated minimum volume and term commitments, then within 30
     days of its receipt of the NIUER quote, Pac-West must either agree to
     purchase under those commitments, cancel its NIUER, or seek mediation or
     arbitration.

F.   If Pac-West has agreed to minimum volume and term commitments under the
     preceding paragraph, Pac-West may cancel the NIUER or volume and term
     commitment at any time, but in the event of such cancellation Pac-West will
     pay USWC's reasonable development costs incurred in providing the
     interconnection or network element, to the extent that those development
     costs are not otherwise amortized.

G.   If either Party believes that the other Party is not requesting,
     negotiating or processing any NIUER in good faith, or disputes a
     determination, or quoted price or cost, it may seek arbitration or
     mediation under (S)252 of the Act.  Pac-West is not required to use this
     section as the exclusive method of seeking access to interconnection or
     Network Elements.

                                                                         Page 58

XXIV.  AUDIT PROCESS

     "Audit" shall mean the comprehensive review of:

          A.   data used in the billing process for services performed and
               facilities provided under this Agreement; and

          B.   data relevant to provisioning and maintenance for services
               performed or facilities provided by either of the Parties for
               itself or others that are similar to the services performed or
               facilities provided under this Agreement for interconnection or
               access to unbundled elements.

     The data referred to in subsection (B), above, shall be relevant to any
     performance standards that are adopted in connection with this Agreement,
     through negotiation, arbitration or otherwise.

     This Audit shall take place under the following conditions:

     A.   Either Party may request to perform an Audit.

     B.   The Audit shall occur upon 30 business days written notice by the
          requesting Party to the non-requesting Party.

     C.   The Audit shall occur during normal business hours.

     D.   There shall be no more than one Audit requested by each Party under
          this Agreement in any 12-month period.

     E.   The requesting Party may review the non-requesting Party's records,
          books and documents, as may reasonably contain information relevant to
          the operation of this Agreement.

     F.   The location of the Audit shall be the location where the requested
          records, books and documents are retained in the normal course of
          business.

     G.   All transactions under this Agreement which are over 24 months old
          will be considered accepted and no longer subject to Audit.

     H.   Each Party shall bear its own expenses occasioned by the Audit,
          provided that the expense of any special data collection shall be born
          by the requesting Party.

     I.   The Party requesting the Audit may request that an Audit be conducted
          by a mutually agreed-to independent auditor.  Under this circumstance,
          the costs of the independent auditor shall be paid for by the Party
          requesting the Audit.

     J.   In the event that the non-requesting Party requests that the Audit be
          performed by an independent auditor, the Parties shall mutually agree
          to the selection of the independent auditor.  Under this circumstance,
          the costs of the independent auditor shall be shared equally by the
          Parties.

                                                                         Page 59
<PAGE>

     K.   The Parties agree that if an Audit discloses error(s), the Party
          responsible for the error(s) shall, in a timely manner, undertake
          corrective action for such error(s).

     All information received or reviewed by the requesting Party or the
     independent auditor in connection with the Audit is to be considered
     Proprietary Information as defined by this Agreement.  The non-requesting
     Party reserves the right to require any non-employee who is involved
     directly or indirectly in any Audit or the resolution of its findings as
     described above to execute a nondisclosure agreement satisfactory to the
     non-requesting Party.  To the extent an Audit involves access to
     information of other competitors, Pac-West and USWC will aggregate such
     competitors' data before release to the other Party, to insure the
     protection of the proprietary nature of information of other competitors.
     To the extent a competitor is an affiliate of the party being audited
     (including itself and its subsidiaries), the Parties shall be allowed to
     examine such affiliates' disaggregated data, as required by reasonable
     needs of the audit.

                                                                         Page 60
<PAGE>

XXV. AUDIOTEXT AND MASS ANNOUNCEMENT SERVICES

     The Parties agree that access to the audiotext, mass announcement and
     information services of each Party should be made available to the other
     Party upon execution of an agreement defining terms for billing and
     compensation of such calls.  Services included in this category include 976
     calls, whether flat rated or usage sensitive, intra-LATA 900 services and
     other intra-LATA 976-like services.  Such calls will be routed over the
     Local Interconnection Trunks.

     Pac-West and USWC will work together in good faith to negotiate and
     execute the agreement for billing and compensation for these services
     within 90 days of the execution of this Agreement.  The Parties agree that
     their separate agreement on audiotext and mass announcement services will
     include details concerning the creation, exchange and rating of records,
     all of which will occur without any explicit charge between the Parties, as
     well as a process for the handling of uncollectables so that the
     originating Party does not have any responsibility for uncollectables.

     Until such time that such an agreement is executed, Pac-West may choose
     to block such calls, or Pac-West will agree to back-bill and compensate
     retroactively for such calls once the subsequent agreement is executed
     retroactive to the effective date of this Agreement.

     A.   Usage Sensitive Compensation.
          ----------------------------

               All audiotext and mass announcement calls shall be considered
               toll calls for purposes of reciprocal compensation between the
               Parties. Compensation will be paid based on the compensation for
               toll calls referenced in this Agreement with respect to
               reciprocal compensation between the Parties, except that such
               compensation shall be paid by the Party terminating the call,
               rather than the Party originating the call.

     B.   Billing and Collection Compensation.
          ------------------------------------

               Billing and collection compensation will be dealt with in the
               agreement referenced in this section.

                                                                         Page 61
<PAGE>

XXVI.  LOCAL INTERCONNECTION DATA EXCHANGE FOR BILLING

There are certain types of calls or types of interconnection that require
exchange of billing records between the Parties, including, for example,
alternate billed and Toll Free Service calls.  The Parties agree that all call
types must be routed between the networks, accounted for, and settled among the
parties.  Certain calls will be handled via the Parties' respective operator
service platforms.  The Parties agree to utilize, where possible and
appropriate, existing accounting and settlement systems to bill, exchange
records and settle revenue.

     A.   The exchange of billing records for alternate billed calls (e.g.,
                                                                      ----
          calling card, bill-to-third number, and collect) will be distributed
          through the existing CMDS processes, unless otherwise separately
          agreed to by the Parties.

     B.   Inter-Company Settlements ("ICS") revenues will be settled through the
          Calling Card and Third Number Settlement System ("CATS").  Each Party
          will provide for its own arrangements for participation in the CATS
          processes, through direct participation or a hosting arrangement with
          a direct participant.

     C.   Non-ICS revenue is defined as collect calls, calling card calls, and
          billed to third number calls which originate on one service provider's
          network and terminate on another service provider's network in the
          same Local Access Transport Area ("LATA").  The Parties agree to
          negotiate and execute an Agreement within 30 days of the execution of
          this Agreement for settlement of non-ICS revenue.  This separate
          arrangement is necessary since existing CATS processes do not permit
          the use of CATS for non-ICS revenue.  The Parties agree that the CMDS
          system can be used to transport the call records for this traffic.

     D.   Both Parties will provide the appropriate call records to the
          intraLATA Toll Free Service Provider, thus permitting the Service
          Provider to bill its subscribers for the inbound Toll Free Service.
          No adjustments to bills via tapes, disks or NDM will be made without
          the mutual agreement of the Parties.

                                                                         Page 62

XXVII. SIGNALING ACCESS TO CALL-RELATED DATABASES

          1.   When Pac-West is purchasing local switching from USWC, USWC will
               provide access via the STP to call related databases used in AIN
               services.  The Parties agree to work in the industry to define
               the mediated access mechanisms for SCP access.  Access to the
               USWC SMS will be provided to CLEC to create, modify, or update
               information in the call related databases, equivalent to the USWC
               access.

          2.   USWC will offer unbundled signaling via LIS-Common Channel
               Signaling Capability (CCSAC). CCSAC service utilizes the SS7
               network and provides access to call-related databases that reside
               at USWC's SCPs, such as the Line Information Database (LIDB) and
               the 800 Database. The access to USWC's SCPs will be mediated via
               the STP Port in order to assure network reliability.

          3.   CCSAC includes:

               a.   Entrance Facility - This element connects Pac-West's
                    signaling point of interface with the USWC serving wire
                    center (SWC).  Pac-West may purchase this element or it may
                    self-provision the entrance facility.  If the entrance
                    facility is self-provisioned, Pac-West would need to
                    purchase collocation and an expanded interconnection channel
                    termination.

               b.   Direct Link Transport (DLT) - This element connects the SWC
                    to the USWC STP.  Pac-West may purchase this element or
                    self-provision transport directly to the STP.  If Pac-West
                    provides the link to the STP, it must purchase collocation
                    and an expanded interconnection channel termination at the
                    STP location.

               c.   STP Port - This element provides the switching function at
                    the STP.  One STP Port is required for each DLT Link.  The
                    Port provides access to the Service Control Point (SCP).

          4.   Access to Advanced Intelligent Network (AIN) functions is
               available only through the STP.

          5.   USWC will provide access to Service Management Systems (SMS)
               through its Service Creation Environment (SCE) on an equivalent
               basis as USWC provides to itself.  SMS allows Pac-West to create
               modify, or update information in call related databases.
               Currently, the SCE process is predominantly manual.

          6.   The pricing for CCSAC service is provided in Appendix A.

                                                                         Page 63
<PAGE>

XXVIII.   INTERCONNECTION TO LINE INFORMATION DATA BASE (LIDB)

          1.   Description of Line Information Data Base (LIDB).

               Line Information Data Base (LIDB) stores various line numbers and
               Special Billing Number (SBN) data used by operator services
               systems to process and bill calls.  The operator services system
               accesses LIDB data to provide origination line (calling number),
               billing number and termination line (called number) management
               functions.  LIDB is used for calling card validation, fraud
               verification, preferred IC association with the calling card,
               billing or service restrictions and the sub-account information
               to be included on the call's billing record.

          2.   Interfaces.

               Bellcore's GR-446-CORE defines the interface between the
               administration system and LIDB including specific message
               formats. (Bellcore's TR-NWP-000029, Section 10)

          3.   LIDB Access.

               a.   All LIDB queries and responses from operator services
                    systems and end offices are transmitted over a CCS network
                    using a Signaling System 7 (SS7) protocol (TR-NWT-000246,
                    Bell Communications Research Specification of Signaling
                    System 7).

               b.   All LIDB queries and responses from the Public Packet
                    Switched Network (PPSN) nodes are transmitted over one or
                    more PPSN as TR-TSY000301 describes.  The application data
                    needed for processing LIDB data are formatted as TCAP
                    messages.  TCAP messages may be carried as an application
                    level protocol network using SS7 protocols for basic message
                    transport.

               c.   The SCP node provides all protocol and interface support.
                    CLEC SS7 connections will be required to meet Bellcore's
                    GR905.  TR954 and USWC's Technical Publication 77342
                    specifications.

               d.   Non-USWC companies will submit LIDB updates through the
                    exchange carrier service center and the LSS service bureau.
                    These two centers enter information into USWC's service
                    order process interface system, SOPI.

               e.   It is currently USWC's policy to allow LIDB access to non-
                    USWC companies through regional STPs.

          4.   Pricing for LIDB access shall be determined on a case-by-case
               basis.

                                                                         Page 64

XXIX.  CONSTRUCTION CHARGES

       The following terms relating to construction charges are taken from OPUC
       Decision 96-324, Appendix A (Arbitrator's Decision):

          Construction costs are included in the recurring price for the
          particular service.  Allowing USWC to recover construction costs in
          the price and also impose an additional construction charge would
          allow the company to recover the same costs twice.  Furthermore,
          including these costs in the price fairly allocates the cost of
          constructing new facilities to all the competitors.  USWC can address
          the abandonment problem by negotiating term commitments before
          constructing outside plant for Pac-West.  When dealing with
          interconnectors that impose a significant risk of nonpayment, USWC can
          require reasonable security that will assure recovery of costs.  See
          Order No. 96-128.

       The following terms relating to construction charges were directed to be
       added to the above by Section 3 of OPUC Decision 96-324:

          Requiring the customer to pay for construction as an up-front charge
          has two problems.  First, it would require the competitor to pay for
          the service twice:  once in the advance charge and again in the
          recurring charge.  In addition, charging the first competitor for the
          construction imposes all the costs on that entity.  Subsequent
          competitors would be able to request service using the facilities paid
          for by the first competitor.  USWC has not proposed any mechanism that
          avoids these concerns.

          It is clear that USWC is entitled to recover its costs of
          construction.  In situations where recovery through recurring charges
          is uncertain, USWC may take reasonable steps to insure cost recovery.
          For example, in situations involving temporary facilities or
          facilities to be constructed in advance of use, USWC may take
          reasonable steps to insure cost recovery.  Those steps include, but
          are not limited to:  term contracts, bonds or other security, or
          advance payment of construction charges.

          Our decision on this issue is consistent with the FCC Rules and Order
          relating to General Rate Structure, which set out principles for
          analyzing rate structure questions and developing methods of recovery
          of costs.  (See (S) 51.507, (P)(P) 743-754).

       The following terms relating to construction charges were issued as a
       supplement to the above language by OPUC Decision 97-126 (Order on
       Reconsideration):

          As a general matter, the costs of providing a network element or
          service are included in the TELRIC-based price of that element or
          service.  However, where an ILEC incurs additional costs to build or
          modify facilities for the benefit of a requesting carrier, and those
          costs are not included in existing rates, the ILEC is entitled to
          recover such additional costs.  The ILEC has the burden of showing
          that any claimed additional costs are not already recovered through
          its existing rates.

                                                                         Page 65
<PAGE>

          If an ILEC demonstrates that it is entitled to recover additional
          costs to provide facilities on behalf of a requesting carrier, it may
          propose to recover those costs through nonrecurring charges.  However,
          because large up-front charges tend to discourage competition, the
          Commission will attempt to spread cost recovery over a reasonable
          period of time and allocate such costs among all requesting carriers.
          This approach is consistent with that approved by the FCC in 47 C.F.R.
          (S)51.507(e).  See also Order No. 96-283 at 13-14 and Order No. 96-
          325, Appendix A at 11;  FCC Order at (P)(P) 682, 743-752.

                                                                         Page 66

XXX.   RESALE

       A. Description

          1.   USWC Basic Exchange Telecommunications Service (as defined in
               Section III) will be available for resale from USWC pursuant to
               the Act and will reference terms and conditions (except prices)
               in USWC tariffs, where applicable.  Appendix A lists services
               which are available for resale under this Agreement, and is
               attached and incorporated herein by this reference.

          2.   Certain USWC services are not available for resale under this
               Agreement. USWC's Telecommunication Services which are not
               available for resale are identified in Appendix A.

          3.   Certain USWC services shall be available for resale at prices
               absent a wholesale discount.  Such services include residence
               exchange service, private line, special access and switched
               access services, and packages of services comprised of services
               available for resale separately.  These services are listed in
               Appendix A.

          4.   Pac-West may contest the legality of any resale restrictions in a
               USWC retail tariff through a complaint filed with the State
               Commission.

       B. Scope

          1.   Basic Exchange Telecommunications Service may be resold only  to
               the same class of customer to which USWC sells local Basic
               Exchange Telecommunications Service.  For example:

               a)   Residence service may not be resold to business customers;

               b)   Basic Exchange Telecommunications Service may not be resold
                    as a substitute for switched access service.

          2.   USWC shall bill Pac-West and Pac-West is responsible for all
               applicable charges for the resold services.  Pac-West shall be
               responsible for all charges associated with services that Pac-
               West resells to an end user.

       C. Ordering and Maintenance.

          1.   Pac-West, or Pac-West's agent, shall act as the single point of
               contact for its end users' service needs, including without
               limitation, sales, service design, order taking, provisioning,
               change orders, training, maintenance, trouble reports, repair,
               post-sale servicing, billing, collection and inquiry.  Pac-West
               shall make it clear to its end users that they are customers of
               the Pac-West for resold services.  Pac-West's end users
               contacting USWC will be instructed to contact Pac-West; however,
               nothing in this

                                                                         Page 67
<PAGE>

               Agreement shall be deemed to prohibit USWC from discussing its
               products and services with Pac-West's customers who call USWC for
               any reason.

          2.   Pac-West shall transmit to USWC all information necessary for the
               installation (billing, listing and other information), repair,
               maintenance and post-installation servicing according to USWC's
               standard procedures, as described in the USWC resale operations
               guide that will be provided to Pac-West.  When USWC's end user or
               the end user's new service provider discontinues the end user's
               service in anticipation of moving to another service provider,
               USWC will render its closing bill to end user customer effective
               with the disconnection.  Should Pac-West's end user customer, a
               new service provider or Pac-West request service be discontinued
               to the end user, USWC will issue a bill to Pac-West for that
               portion of the service provided to Pac-West.  USWC will notify
               Pac-West by FAX, EDI, or other processes when end user moves to
               another service provider.  Pac-West shall issue disconnect orders
               to USWC, which shall be coordinated with new connect orders
               issued by the new service provider

          3.   Resold services shall be installed and repaired in a manner
               consistent with USWC's effective tariffs with the same quality
               and timeliness that USWC provides to its own end users.

          4.   Pac-West shall provide USWC and USWC shall provide Pac-West with
               points of contact for order entry, problem resolution and repair
               of the resold services.

          5.   Prior to placing orders on behalf of the USWC customer, Pac-West
               shall be responsible for obtaining and have in its possession a
               Letter of Authorization or Agency (LOA) from the end user.  Pac-
               West shall make LOAs available to USWC upon request.

               Prior to placing orders that will disconnect a line from another
               reseller's account Pac-West is responsible for obtaining all
               information needed to process the disconnect order and re-
               establish the service on behalf of the end user.  If Pac-West is
               displaced by another reseller or service provider, Pac-West is
               responsible for coordination with the other reseller or service
               provider.  Should an end user dispute or a discrepancy arise
               regarding the authority of Pac-West to act on behalf of the end
               user, Pac-West is responsible for providing written evidence of
               its authority to USWC within three (3) business days.  If there
               is a conflict between the end user designation and Pac-West's
               written evidence or its authority, USWC shall honor the
               designation of the end user and change the end user back to the
               previous service provider.  If Pac-West does not provide the LOA
               within three (3) business days, or if the end user disputes the
               authority of the LOA, then Pac-West must, by the end of the third
               business day:

                                                                         Page 68
<PAGE>

                    a)  notify USWC to change the end user back to the previous
                        reseller or service provider, and

                    b)  provide any end user information and billing records
                        Pac-West has obtained relating to the end user to the
                        previous reseller, and

                    c)  notify the end user and USWC that the change has been
                        made, and

                    d)  remit to USWC a slamming charge as provided in Appendix
                        A as compensation for the change back to the previous
                        reseller or service provider.

          6.   Pac-West shall designate the Primary Interexchange Carrier (PIC)
               assignments on behalf of its end users for interLATA services and
               intraLATA services when intraLATA presubscription is implemented.

     D.   Pac-West Responsibilities

          1.   Pac-West must send USWC complete and accurate end-user listing
               information for Directory Assistance, Directory, and 911
               Emergency Services using the established processes of USWC.  Pac-
               West must provide to USWC accurate end-user information to ensure
               appropriate listings in any databases in which USWC is required
               to retain and/or maintain end-user information.  USWC assumes no
               liability for the accuracy of information provided by Pac-West.

          2.   Pac-West may not reserve blocks of USWC telephone numbers, except
               as allowed by tariffs.

          3.   Pac-West is liable for all fraud associated with service to its
               end-users and accounts.  USWC takes no responsibility, and will
               make no adjustments to Pac-West's account in cases of fraud.  The
               Parties will cooperate in the prevention and investigation of
               fraudulent use of resold services.

          4.   This agreement does not address the resale of USWC provided
               calling cards.

          4.   Pac-West will provide a three year forecast within ninety (90)
               days of signing this Agreement.  The forecast shall be updated
               and provided to USWC on a quarterly basis in as specified in
               Appendix B.  The initial forecast will provide:

                    .  The date service will be offered (by city and/or state)
                    .  The type and quantity of service(s) which will be offered
                    .  Pac-West's anticipated order volume

                                                                         Page 69
<PAGE>

                    .  Pac-West's key contact personnel

          5.   In the event USWC terminates the provisioning of any resold
               services to Pac-West for any reason, Pac-West shall be
               responsible for providing any and all necessary notice to its end
               users of the termination.  In no case shall USWC be responsible
               for providing such notice.

     E.   Rates and Charges

          1.   Resold services as listed in Appendix A are available for resale
               at the applicable resale tariff rates or at the rates or at the
               wholesale discount levels set forth in Appendix A.

          2.   If the resold services are purchased pursuant to Tariffs and the
               Tariff rates change, charges billed to Pac-West for such services
               will be based upon the new Tariff rates less the applicable
               wholesale discount as agreed to herein.  The new rate will be
               effective upon the Tariff effective date.

          3.   A Customer Transfer Charge (CTC) as specified in Appendix A
               applies when transferring any existing account or lines to Pac-
               West.

          4.   A Subscriber Line Charge (SLC) will continue to be paid by Pac-
               West without discount for each local exchange line resold under
               this Agreement.  All federal and state rules and regulations
               associated with SLC as found in the applicable tariffs also
               apply.

          5.   Pac-West will pay to USWC the PIC change charge without discount
               associated with Pac-West end user changes of inter-exchange or
               intraLATA carriers.

          6.   Pac-West agrees to pay USWC when its end user activates any
               services or features that are billed on a per use or per
               activation basis (e.g., continuous redial, last call return, call
               back calling, call trace, etc.).  USWC shall provide Pac-West
               with detailed billing information (per applicable OBF standards,
               if any) as necessary to permit Pac-West to bill its end users
               such charges.

          7.   To the extent such charges apply to USWC's retail customers,
               special construction charges, line extension charges, and land
               development agreements may apply to Pac-West, as detailed in
               individual state tariffs regarding end user obligations for
               construction charges.  Specifically, special construction charges
               will be applicable where, at the request of Pac-West on behalf of
               its customers, USWC constructs a greater quantity of facilities
               than that which USWC would otherwise construct or normally
               utilize.

                                                                         Page 70
<PAGE>

          8.   Nonrecurring charges will be billed at the applicable Tariff
               rates, less the appropriate wholesale discount.

          9.   As part of the resold line, USWC provides operator services,
               directory assistance, and IntraLATA long distance with standard
               USWC branding.  At the request of Pac-West and where technically
               feasible USWC will rebrand operator services and directory
               assistance in Pac-West's name, provided the costs associated with
               such rebranding are paid by Pac-West.  Pac-West will have the
               option of obtaining such services on an unbranded basis, at no
               additional cost for "unbranding" the service.

          10.  USWC will address all Pac-West requests for ancillary resale
               systems, programs, and initiatives on an individual case basis.

     F.   Directory Listings

          As part of each resold line, USWC will accept at no charge one primary
          listing for each main telephone number belonging to Pac-West's end
          user customer based on end user information provided to USWC by Pac-
          West.  USWC will place Pac-West's listings in USWC's directory listing
          database for directory assistance purposes and will make listings
          available to directory publishers and to other third parties.
          Additional terms and conditions with respect to directory listings are
          described in Section XV, Directory Listings, herein..

     G.   Deposit

          1.   USWC may require Pac-West to make a suitable deposit to be held
               by USWC as a guarantee of the payment of charges.  Any deposit
               required of an existing reseller is due and payable within ten
               days after the requirement is imposed.  The amount of the deposit
               shall be the estimated charges for the resold service which will
               accrue for a two-month period.  Interest on the deposit shall be
               accumulated by USWC at a rate equal to the federal discount rate,
               as published in the Wall Street Journal from time to time.

          2.   When the service is terminated, or when Pac-West has established
               satisfactory credit, the amount of the initial or additional
               deposit, with any interest due, will, at Pac-West's option,
               either be credited to Pac-West's account or refunded.
               Satisfactory credit for a reseller is defined as twelve
               consecutive months service as a reseller without a termination
               for nonpayment and with no more than one notification of intent
               to terminate Service for nonpayment.

                                                                         Page 71
<PAGE>

     H.   Payment

          1.   Amounts payable under this Agreement are due and payable within
               thirty (30) days after the date of USWC's invoice.

          2.   A late payment charge of 1.5% applies to all billed balances
               which are not paid by the billing date shown on the next bill.
               To the extent Pac-West pays the billed balance on time, but the
               amount of the billed balance is disputed by Pac-West, and, it is
               later determined that a refund is due Pac-West, interest shall be
               payable on the refunded amount in the amount of 1.5% per month.

          3.   USWC may discontinue processing orders for the failure by Pac-
               West to make full payment for the resold services provided under
               this Agreement within thirty (30) days of Pac-West's receipt of
               bill.

          4.   USWC may disconnect for the failure by Pac-West to make full
               payment for the resold services provided under this Agreement
               within sixty (60) days of Pac-West's receipt of bill.

          5.   Collection procedures and the requirements for deposit are
               unaffected by the application of a late payment charge.

          6.   In the event USWC terminates the provisioning of any resold
               services to Pac-West for any reason, Pac-West shall be
               responsible for providing any and all necessary notice to its end
               users of the termination.  In no case shall USWC be responsible
               for providing such notice.

          7.   USWC shall bill all amounts due from Pac-West for each resold
               service in accordance with the terms and conditions as specified
               in the USWC tariff.

                                                                         Page 72

XXXI.  UNBUNDLED ACCESS/ELEMENTS

     A.  General Terms

         1.  USWC agrees to provide the following unbundled network elements
             which are addressed in more detail in later sections of this
             agreement: 1) local loop, 2) local and tandem switches (including
             all vertical switching features provided by such switches, 3)
             interoffice transmission facilities, 4) network interface devices,
             5) signaling and call-related database facilities, 6) operations
             support systems functions, and 7) operator and directory assistance
             facilities.

         2.  (deleted)/6/

         3.  USWC will not restrict the types of telecommunications services
             Pac-West may offer through unbundled elements, nor will it restrict
             Pac-West from combining elements with any technically compatible
             equipment the Pac-West owns. USWC will provide Pac-West with all of
             the functionalities of a particular element, so that Pac-West can
             provide any telecommunications services that can be offered by
             means of the element. USWC agrees to perform and Pac-West agrees to
             pay for the functions necessary to combine requested elements in
             any technically feasible manner either with other elements from
             USWC's network, or with elements possessed by Pac-West. However,
             USWC need not combine network elements in any manner requested if
             not technically feasible, but must combine elements ordinarily
             combined in its network in the manner they are typically combined.

     B.  Description of Unbundled Elements

     1.  Tandem Switching

               USWC will provide a tandem switching element on an unbundled
               basis.  The tandem switch element includes the facilities
               connecting the trunk distribution frames to the switch, and all
               the functions of the switch itself, including those facilities
               that establish a temporary transmission path between two other
               switches.  The definition of the tandem switching element also
               includes the functions that are centralized in tandems rather
               than in separate end office switches, such as call recording, the
               routing of calls to operator services, and signaling conversion
               functions.

     2.  Transport

               USWC will provide unbundled access to shared transmission
               facilities between end offices and the tandem switch.  Further,
               USWC will provide unbundled access to dedicated transmission
               facilities between its central

     (Arbitrator's Decision).

                                                                         Page 73

               offices or between such offices and those of competing carriers.
               This includes, at a minimum, interoffice facilities between end
               offices and serving wire centers (SWCs), SWCs and IXC POPs,
               tandem switches and SWCs, end offices or tandems of USWC , and
               the wire centers of USWC and requesting carriers. USWC will also
               provide all technically feasible transmission capabilities, such
               as DS1, DS3, and Optical Carrier levels (e.g. OC-3/12/48/96) that
               Pac-West could use to provide telecommunications services.

     3.  Digital Cross Connect System.

               USWC will provide Pac-West with access to mutually agreed upon
               digital cross-connect system (DCS) points.

     4.  Unbundled Loops

               a.   Service Description

                    i.   An Unbundled Loop establishes a transmission path
                         between the USWC distribution frame (or equivalent) up
                         to, and including, USWC's network interface device
                         (NID).  For existing loops, the inside wire connection
                         to the NID will remain intact.

                    ii.  Basic Unbundled Loops are available as a two-wire or
                         four-wire, point-to-point configuration suitable for
                         local exchange type services within the analog voice
                         frequency range of 300 to 3000 Hz.  For the two-wire
                         configuration, Pac-West is requested to specify loop
                         start, ground start or loop reverse battery options.
                         The actual loop facilities that provide this service
                         may utilize various technologies or combinations of
                         technologies.  Basic Unbundled Loops provide an analog
                         facility to Pac-West.

                         (a)  To the extent Pac-West requires an Unbundled Loop
                              to provide ISDN, HDSL, ADSL or DS1 service, such
                              requirements will be identified on the order for
                              Unbundled Loop Service.  Conditioning charges will
                              apply, as required, to condition such loops to
                              ensure the necessary transmission standard.

                         (b)  Specific channel performance options for the loops
                              can be ordered by identifying the Network Channel
                              (NC)/Network Channel Interface (NCI) for the
                              functions desired.  USWC will provide Pac-West
                              with the available NC/NCI codes and their
                              descriptions.

                                                                         Page 74
<PAGE>

               b.   Unbundled Loops are provided in accordance with the
                    specifications, interfaces and parameters described in the
                    appropriate Technical Reference Publications.  USWC's sole
                    obligation is to provide and maintain Unbundled Loops in
                    accordance with such specifications, interfaces and
                    parameters.  USWC does not warrant that Unbundled Loops are
                    compatible with any specific facilities or equipment or can
                    be used for any particular purpose or service.  Transmission
                    characteristics may vary depending on the distance between
                    Pac-West's end user and USWC's end office and may vary due
                    to characteristics inherent in the physical network.  USWC,
                    in order to properly maintain and modernize the network, may
                    make necessary modifications and changes to the network
                    elements in its network on an as needed basis.  Such changes
                    may result in minor changes to transmission parameters.
                    Changes that affect network interoperability require advance
                    notice pursuant to Section XIX, Notice of Changes, herein.

               c.   Facilities and lines furnished by USWC on the premises of
                    Pac-West's end user and up to the NID or equivalent are the
                    property of USWC.  USWC must have access to all such
                    facilities for network management purposes.  USWC's
                    employees and agents may enter said premises at any
                    reasonable hour to test and inspect such facilities and
                    lines in connection with such purposes or upon termination
                    or cancellation of the Unbundled Loop Service to remove such
                    facilities and lines.  The Parties agree to explore issues
                    surrounding the extension of Unbundled Loops beyond the NID.

               d.   Unbundled Loops include the facilities between the USWC
                    distribution frame up to and including USWC's NID located at
                    Pac-West's end user premise.  The connection between the
                    distribution frame and Pac-West facilities is accomplished
                    via channel terminations that can be ordered in conjunction
                    with either Collocation or Unbundled Interoffice Transport
                    Service.

               e.   Ordering and Maintenance.

                    i.   For the purposes of loop assignment, tracking, and
                         dispute resolution, USWC will require a Letter of
                         Authorization for each existing USWC end user for which
                         Pac-West has requested reassignment of the loop serving
                         that end user.

                    ii.  If there is a conflict between an end user (and/or its
                         respective agent) and Pac-West regarding the
                         disconnection or provision of Unbundled Loops, USWC
                         will honor the latest dated Letter of Authorization
                         designating an agent by the end user or its respective
                         agent.  If the end user's service has not been
                         disconnected and

                                                                         Page 75
<PAGE>

                         Unbundled Loop Service is not yet established, Pac-West
                         will be responsible to pay the nonrecurring charge as
                         set forth herein. If the end user's service has been
                         disconnected and the end user's service is to be
                         restored with USWC, Pac-West will be responsible to pay
                         the applicable nonrecurring charges as set forth in
                         USWC's applicable tariff, to restore the end user's
                         prior service with USWC.

                    iii. Pac-West is responsible for its own end user base and
                         will have the responsibility for resolution of any
                         service trouble report(s) from its customers.  USWC
                         will work cooperatively with Pac-West to resolve
                         trouble reports when the trouble condition has been
                         isolated and found to be within a portion of USWC's
                         network.  Pac-West must provide to USWC switch-based
                         test results when testing its customer's trouble prior
                         to USWC performing any repair functions.  The Parties
                         will cooperate in developing mutually acceptable test
                         report standards.  USWC shall provide Pac-West with
                         Maintenance of service charges in accordance with
                         applicable time and material charges in USWC tariffs
                         will apply when the trouble is not in USWC's network.

                    iv.  Pac-West will be responsible to submit to USWC a
                         disconnect order for a Unbundled Loop that is
                         relinquished by the end user due to cessation of
                         service. Unbundled Loop facilities will be returned to
                         USWC when the disconnect order is complete.  In the
                         event of transfer of the end user's service from one
                         provider to another, the new provider will issue a
                         request for transfer of service, resulting in the
                         appropriate disconnect/reconnection of service.

                    v.   The installation due date is a negotiated item.  For
                         related orders, new connects will be physically worked
                         within the same calendar day.

                    vi.  When ordering Unbundled Loops, Pac-West is responsible
                         for obtaining or providing facilities and equipment
                         that are compatible with the service.

                    vii.  Pac-West will have responsibility for testing the
                         equipment, network facilities and the Unbundled Loop
                         facility.  If USWC performs tests of the Unbundled Loop
                         facility at Pac-West's request, and the fault is not in
                         the USWC facilities, a charge shall apply.

                                                                         Page 76
<PAGE>

                    viii. Pac-West will be responsible for providing battery
                          and dial tone to its connection point two days prior
                          to the due date on the service order.

                    ix.   The following procedures shall apply to Unbundled
                          Loops ordered with the option of Basic Testing at
                          Coordinated Time:

                          (a)  On each Unbundled Loop order, Pac-West and USWC
                               will agree on a cutover time at least 48 hours
                               before that cutover time. The cutover time will
                               be defined as a 30 minute window within which
                               both the Pac-West and USWC personnel will make
                               telephone contact to complete the cutover.

                          (b)  Within the appointed 30 minute cutover time, the
                               Pac-West person will call the USWC person
                               designated to perform cross-connection work and
                               when the USWC person is reached in that interval
                               such work will be promptly performed. If the Pac-
                               West person fails to call or is not ready within
                               the appointed interval, and if Pac-West had not
                               called to reschedule the work at least 2 hours
                               prior to the start of the interval, USWC and Pac-
                               West will reschedule the work order and Pac-West
                               will pay the non-recurring charge for the
                               Unbundled Loops scheduled for the missed
                               appointment. In addition, non-recurring charges
                               for the rescheduled appointment will apply. If
                               the USWC person is not available or not ready at
                               any time during the 30 minute interval, Pac-West
                               and USWC will reschedule and USWC will waive the
                               non-recurring charge for the Unbounded Loops
                               scheduled for that interval. The standard time
                               expected from disconnection of service on a line
                               to the connection of the Unbundled Loop to the
                               Pac-West Collocation Service is 5 minutes. If
                               USWC causes a line to be out of service due
                               solely to its failure for more than 15 minutes,
                               USWC will waive the non-recurring charge for that
                               Unbundled Loop. If unusual or unexpected
                               circumstances prolong or extend the time required
                               to accomplish the coordinated cut-over, the Party
                               responsible for such circumstances is responsible
                               for the reasonable labor charges of the other
                               Party. Delays caused by the customer are the
                               responsibility of Pac-West. In addition, if Pac-
                               West has ordered INP as a part of the Unbundled
                               Loop installation, USWC will coordinate
                               implementation of INP with the Unbundled Loop

                                                                         Page 77
<PAGE>

                                   installation; provided, separate INP
                                   installation charges will apply.

                     xx..     Pac-West and USWC will work cooperatively to
                              develop forecasts for Unbundled Loop service. USWC
                              requests an eighteen month forecast of Unbundled
                              Loop service. The forecast will include the
                              specific serving Wire Center that will be
                              requested, plus the specific quantity of each
                              service desired. The forecast will be updated
                              quarterly, and will be treated as Pac-West
                              confidential information.

               f.   Appendix A contains the rate information for Unbundled
                    Loops.

               g.   If applicable, the New Interconnection/Unbundled Element
                    Request Process will apply as detailed in Section XXIII of
                    this Agreement.

               h.   For issues related to construction charges, see Section XXIX
                    of this Agreement.

     5.  Local Switching Elements

               The switching network element includes facilities that are
               associated with the line (e.g., the line card), facilities that
               are involved with switching the call, and facilities used for
               custom routing.  USWC will provide the local switching element to
               Pac-West pursuant to the Network Interconnection/Unbundled
               Element Request Process described in Section XXIII herein.


     6.  Network Interface Device (NID)

               a.   Service Description.

                    A device wired between a telephone protector and the inside
                    wiring to isolate the customer's equipment from the network
                    at the subscriber's premises.  It is a device for the
                    termination of inside wire that is available in single and
                    multiple pair configurations.

               b.   Pac-West may connect its loops, via its own NID, to the USWC
                    NID.

               c.   Any costs associated with Pac-West connecting its NID to
                    USWC's NID, will be the responsibility of Pac-West.

               d.   Connecting Pac-West's loop directly to the USWC NID is
                    prohibited.

                                                                         Page 78
<PAGE>

               e.   If Pac-West purchases an unbundled loop, Pac-West may
                    provide its own NID or have USWC provide the NID.

               f.   The price for access to the NID will be provided on a case-
                    by-case basis.

     7.  Additional Unbundled Elements

               USWC shall provide nondiscriminatory access to, and where
               appropriate, development of additional unbundled network elements
               not covered in this Agreement in response to specific requests
               therefor, pursuant to the New Interconnection/Unbundled Element
               Request Process detailed in Section XXIII of this Agreement.

                                                                         Page 79

XXXII. SERVICE STANDARDS

     A.   Definitions

          When used in this Section, the following terms shall have the meanings
          indicated.

          1.   "Specified Performance Commitment" means the commitment by USWC
               to meet the Performance Criteria for any Specified Activity
               during the Specified Review Period.

          2.   "Specified Activity" means any of the following activities:

               a)  The installation by USWC of Unbundled Loops for Pac-West
                   ("Unbundled Loop Installation");

               b)  USWC's provision of Interim Number Portability ("INP
                   Installation") to Pac-West;

               c)  The repair of USWC service provided to Pac-West ("Out of
                   Service Repairs"); or

               d)  The installation by USWC of interconnection trunks for the
                   mutual exchange of local exchange traffic with Pac-West ("LIS
                   Trunk Installation")

          3.   "Performance Criteria" means, with respect to a Specified Review
               Period (i.e., a calendar month or quarter), the performance by
               USWC for the specified activities for Pac-West will meet or
               exceed the average performance by USWC for the total universe of
               specified activities.


     B.   Failure to Meet the Performance Criteria.  If during a Specified
          Review Period, USWC fails to meet the performance criteria, USWC will
          use its best efforts to meet the Performance Criteria for the next
          Specified Review Period.  If USWC fails to meet the performance
          criteria for two consecutive periods, the Parties agree, in good
          faith, to attempt to resolve such issues through negotiation or non-
          binding arbitration.  This paragraph shall not be construed to waive
          either Party's right to seek legal or regulatory intervention as
          provided by state or federal law.  Pac-West may seek regulatory or
          other legal relief including requests for specific performance of
          USWC's obligations under this Agreement.

     C.   Limitations.  USWC's failure to meet or exceed and of the Performance
          Criteria can not be as a result, directly or indirectly, of a Delaying
          Event.  A "Delaying Event" means (a) a failure by Pac-West to perform
          any of its obligations set forth in this Agreement, (b) any delay, act
          or failure to act by a Customer, agent of subcontractor of Pac-West or
          (c) any Force Majeure Event.  If a Delaying Event prevents USWC from
          performing a Specified Activity, then such Specified

                                                                         Page 80
<PAGE>

          Activity shall be excluded from the calculation of USWC's compliance
          with the Performance Criteria.

     D.   Records.  USWC shall maintain complete and accurate records, for the
          Specified Review Period of its performance under this Agreement for
          each Specified Activity and its compliance with the Performance
          Criteria.  USWC shall provide to Pac-West such records in a self-
          reporting format.  The parties agree that such records shall be deemed
          "Proprietary Information".

                                                                         Page 81

          The Parties have agreed to commence discussion of these and other
          implementation issues by November 1, 1996 to facilitate the above

         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 Pac-West' network and to terminate the traffic it receives in that
         standard format or the proper address on its network. Such facility
         shall be designed based upon the description and forecasts provided
         under this Agreement. 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.

         services 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 Customers, and each Party may
         discontinue or refuse service if the other Party violates this
         provision Upon such violation, either Party shall provide the other

          effect from time to time.

     C.   Letter of Authorization

          Where so indicated in specific sections of this Agreement, Pac-West is
          responsible to have a Letter of Authorization.  Pac-West is solely
          responsible to obtain authorization from its end user for the handling
          of the disconnection of the end user's service with USWC, the
          provision of service by Pac-West, and the provision of Unbundled Loops
          and all other ancillary services.  Should a dispute or discrepancy

          authority to USWC.

                                                                         Page 83

               due date stated above shall be subject to a late charge equal to
               either i) 0.03 percent per day compounded daily for the number of
               calendar days from the payment due date to and including, the
               date of payment, that would result in an annual percentage rate
               of 12% or ii) the highest lawful rate, whichever is less.  If
               late payment charges for services are not permitted by local
               jurisdiction, this provision shall not apply.

     E.   Taxes

               Each party purchasing services hereunder shall pay or otherwise
          be responsible for all federal, state, or local sales, use, excise,
          gross receipts, transaction or similar taxes, fees or surcharges
          levied against or upon such purchasing Party (or the providing Party
          when such providing Party is permitted to pass along to the purchasing
          Party such taxes, fees or surcharges), except for any tax on either
          Party's corporate existence, status or income. Whenever possible,
          these amounts shall be billed as a separate item on the invoice. To
          the extent a sale is claimed to be for resale tax exemption, the
          purchasing Party shall furnish the providing Party a proper 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.

     F.   Intellectual Property

          1.   Each Party hereby grants to the other Party the limited, personal
               and nonexclusive right and license to use its patents, copyrights

               services, and for no other purposes.  Nothing in this Agreement
               shall be construed as the grant to the other Party of any rights
               or licenses to trademarks.

          2.   The rights and licenses under Section F. 1. above are granted "AS
               IS" and the other Party's exercise of any such right and license

<PAGE>

               any facilities by either Party under this Agreement constitutes
               infringement, or misuse or misappropriation of any patent,
               copyright, trade secret, or any other proprietary or intellectual
               property right of any third party.

          3.   Pac-West shall not, without the express written permission of
               USWC, state or imply that;  1)  Pac-West is connected, or in any
               way affiliated with USWC or its affiliates,  2)  Pac-West is part
               of a joint business association or any similar arrangement with

               promotional activities or materials, that the resold goods and
               services are in any way associated with or originated from USWC
               or any of its affiliates.  Nothing in this paragraph shall
               prevent Pac-West from truthfully describing the network elements
               it uses to provide service to its customers.

     G.   Severability

          The Parties recognize that the FCC is promulgating rules addressing
          issues contained in this Agreement.  In the event that any one or more
          of the provisions contained herein shall for any reason be held to be
          unenforceable in any respect under law or regulation, the parties will
          negotiate in good faith for replacement language.  If replacement
          language cannot be agreed upon, either party may seek regulatory
          intervention, including negotiations pursuant to Sections 251 and 252
          of the Act.

     H.   Responsibility for Environmental Contamination.

          Neither Party shall be liable to the other for any costs whatsoever
          resulting from the presence or Release of any Environmental Hazard
          that either Party did not introduce to the affected Work Location.
          Both Parties shall defend and hold harmless the other, its officers,
          directors and employees from and against any losses, damages, claims,
          demands, suits, liabilities, fines, penalties and expenses (including
          reasonable attorneys' fees) that arise out of or result from (i) any
          Environmental Hazard that the indemnifying party, its contractors or
          agents introduce to the Work Locations or (ii) the presence or Release
          of any Environmental Hazard for which the indemnifying party is
          responsible under Applicable Law.

     I.   Responsibility of Each Party

          Each Party is an independent contractor, and has and hereby retains
          the right to exercise full control of and supervision over its own
          performance of its obligations under this Agreement and retains full
          control over the employment, direction, compensation and discharge of
          all employees assisting in the performance of such obligations.  Each
          Party will be solely responsible for all matters relating to payment
          of such employees, including compliance with social security taxes,
          withholding taxes and all other regulations governing such

                                                                         Page 85

          matters. Each Party will be solely responsible for proper handling,
          storage, transport and disposal at its own expense of all (i)
          substances or materials that it or its contractors or agents bring to,
          create or assume control over at work locations or, (ii) waste
          resulting therefrom or otherwise generated in connection with its or
          its contractors' or agents' activities at the work locations. Subject
          to the limitations on liability and except as otherwise provided in
          this Agreement, each Party shall be responsible for (i) its own acts

          technical reference, technical publication, Pac-West practice, USWC
          practice, or publication of industry standards (unless Pac-West elects
          otherwise).  Should there by any inconsistency between or among
          publications or standards, Pac-West shall elect which requirement
          shall apply.

          The Parties' obligations under this Agreement which by their nature

          Agreement, the Parties agree to work cooperatively, promptly and in
          good faith to negotiate and implement any such additions, changes and
          corrections to this Agreement.

                                                                         Page 87
<PAGE>

     T.   Indemnity


          1.   Each of the Parties agrees to release, indemnify, defend and hold
               harmless the other Party and each of its officers, directors,
               employees and agents (each an "Indemnitee") from and against and
               in respect of any loss, debt, liability, damage, obligation,
               claim, demand, judgment or settlement of any nature or kind,
               known or unknown, liquidated or unliquidated including, but not
               limited to, costs and attorneys' fees, whether suffered, made,
               instituted, or asserted by any other party or person, for
               invasion of privacy, personal injury to or death of any person or
               persons, or for loss, damage to, or destruction of property,
               whether or not owned by others, resulting from the indemnifying
               Party's performance, breach of Applicable Law, or status of its
               employees, agents and subcontractors; or for failure to perform
               under this Agreement, regardless of the form of action.

          2.  The indemnification provided herein shall be conditioned upon:

               a.   The indemnified Party shall promptly notify the indemnifying
                    Party of any action taken against the indemnified Party
                    relating to the indemnification.  Failure to so notify the
                    Indemnifying Party shall not relieve the Indemnifying Party
                    of any liability that the Indemnifying Party might have,
                    except to the extent that such failure prejudices the
                    Indemnifying Party's ability to defend such claim.

               b.   The indemnifying Party shall have sole authority to defend
                    any such action, including the selection of legal counsel,
                    and the indemnified Party may engage separate legal counsel
                    only at its sole cost and expense.

               c.   In no event shall the indemnifying Party settle or consent
                    to any judgment pertaining to any such action without the
                    prior written consent of the indemnified Party.

     U.   Limitation of Liability

          1)  Except as otherwise provided in the indemnity section, no Party
              shall be liable to the other Party for any Loss, defect or
              equipment failure caused by the conduct of the other Party, the
              other Party's agents, servants, contractors or others acting in

              obligations under this Section shall be limited to, that portion
              (as mutually agreed to by the Parties) of the resulting expense

                                                                         Page 88

          services provided to the other Party under this Agreement comply with
          CALEA.  Each party shall indemnify and hold the other Party harmless
          from any and all penalties imposed upon the other Party for such
          noncompliance and shall at the non-compliant Party's sole cost and
          expense, modify or replace any equipment, facilities or services

          equipment, facilities and services fully comply with CALEA.

     BB.  Independent Contractor

          Each party shall perform services hereunder as an independent
          contractor and nothing herein shall be construed as creating any other
          relationship between the Parties.  Each party and each Party's
          contractor shall be solely responsible for the withholding or payment
          of all applicable federal, state and local income taxes, social
          security taxes and other payroll taxes with respect to their

          acts.  Each party has sole authority and responsibility to hire, fire
          and otherwise control its employees.

     CC.  Force Majeure

          of any part of this Agreement from any cause beyond its control and

          labor dispute or strike the Parties agree to provide service to each
          other at a level equivalent to the level they provide themselves.


     DD.  Dispute Resolution

          controversy or dispute between the Parties, their agents, employees,
          officers, directors or affiliated agents ("Dispute") through
          negotiation or non-binding arbitration.  This paragraph shall not be
          construed to waive the Parties' rights to seek legal or regulatory
          intervention as provided by state or federal law.

     EE.  Commission Decision

          This Agreement shall at all times be subject to such review by the
          Commission or FCC as permitted by the Act.  If any such review renders
          the Agreement inoperable or creates any ambiguity or requirement for
          further amendment to the Agreement, the Parties will negotiate in good
          faith to agree upon any necessary amendments to the Agreement.

     FF.  Nondisclosure

          1. All information, including but not limited to specifications,
             microfilm, photocopies, magnetic disks, magnetic tapes, drawings,

             employee records, maps, financial reports, and market data, (i)

             graphic, electromagnetic, or other tangible form and marked at the
             time of delivery as "Confidential" or "Proprietary", or (iii)
             communicated orally and declared to the receiving Party at the time
             of delivery, or by written notice given to the receiving Party

             "Proprietary" (collectively referred to as "Proprietary
             Information"), shall remain the property of the disclosing Party. A
             Party who receives Proprietary Information via an oral
             communication may request written confirmation that the material is
             Proprietary Information. A Party who delivers Proprietary
             Information via an oral communication may request written
             confirmation that the Party receiving the information understands
             that the material is Proprietary Information.

          2. Upon request by the disclosing Party, the receiving Party shall
             return all tangible copies of Proprietary Information, whether
             written, graphic or

                                                                         Page 91
<PAGE>

             otherwise, except that the receiving Party may retain one copy for
             archival purposes.

          3. Each Party shall keep all of the other Party's Proprietary
             Information confidential and shall use the other Party's
             Proprietary Information only in connection with this Agreement.
             Neither Party shall use the other Party's Proprietary Information
             for any other purpose except upon such terms and conditions as may
             be agreed upon between the Parties in writing.

          4. Unless otherwise agreed, the obligations of confidentiality and
             non-use set forth in this Agreement do not apply to such
             Proprietary Information as:

              a.  was at the time of receipt already known to the receiving
                  Party free of any obligation to keep it confidential evidenced
                  by written records prepared prior to delivery by the
                  disclosing Party; or

              b.  is or becomes publicly known through no wrongful act of the
                  receiving Party; or

              c.  is rightfully received from a third person having no direct or
                  indirect secrecy or confidentiality obligation to the
                  disclosing Party with respect to such information; or

              d.  is independently developed by an employee, agent, or
                  contractor of the receiving Party which individual is not
                  involved in any manner with the provision of services pursuant
                  to the Agreement and does not have any direct or indirect
                  access to the Proprietary Information; or

              e.  is disclosed to a third person by the disclosing Party without
                  similar restrictions on such third person's rights; or

              f.  is approved for release by written authorization of the
                  disclosing Party; or

              g.  is required to be made public by the receiving Party pursuant
                  to applicable law or regulation provided that the receiving
                  Party shall give sufficient notice of the requirement to the
                  disclosing Party to enable the disclosing Party to seek
                  protective orders.

         5. Effective Date Of This Section.  Notwithstanding any other provision
            of this Agreement, the Proprietary Information provisions of this
            Agreement shall apply to all information furnished by either Party

            if furnished before the date of this Agreement.

                                                                         Page 92

     HH.  Assignment

          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 prior
          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.

     II.  Warranties

          NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, THE PARTIES
          AGREE THAT NEITHER PARTY HAS MADE, AND THAT THERE DOES NOT EXIST, ANY
          WARRANTY, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES
          OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

                                                                         Page 93

     JJ.  Default

          If either Party defaults in the payment of any amount due hereunder,
          or if either Party violates any other provision of this Agreement, and
          such default or violation shall continue for thirty (30) days after
          written notice thereof, the other Party may seek legal and/or
          regulatory relief.  The failure of either Party to enforce any of the
          provisions of this Agreement or the waiver thereof in any instance
          shall not be construed as a general waiver or relinquishment on its
          part of any such provision, but the same shall, nevertheless, be and
          remain in full force and effect.

     KK.  No Third Party Beneficiaries

          Except as may be specifically set forth in this Agreement, this
          Agreement does not provide and shall not be construed to provide third
          parties with any remedy, claim, liability, reimbursement, cause of
          action, or other privilege.

   does not indicate agreement with all aspects of the Arbitrator's/Commission's
   decision, nor does it waive any of either party's rights to seek judicial or
   administrative review of all or part of the agreement, or to reform the
   agreement as the result of successful judicial or administrative review.


*  This Agreement is made pursuant to Section 252 (i) of the Act and is premised
upon the Interconnection Agreement between MFS Intelenet, Inc. and U S WEST
Communications, Inc.

                                                                         Page 94

(the "Underlying Agreement"). The Underlying Agreement was approved by the
Commission on August 21, 1997.

With respect to this Agreement, the Parties understand and agree:

i)   The Parties shall request the Commission to expedite its review and
approval of this Agreement.

ii)  Notwithstanding the mutual commitments set forth herein, the Parties are
entering into this Agreement without prejudice to any positions they have taken
previously, or may take in the future, in any legislative, regulatory, or other
public forum addressing any matters, including those relating to the types of
arrangements contained in this Agreement.  During the proceeding in which the
Commission is to review and approve the Agreement, U S WEST may point out that
it has objected, and continues to object, to the inclusion of the terms and
conditions to which it objected in the proceedings involving the approval of the
Underlying Agreement.

iii) This Agreement contains provisions based upon the decisions and orders of
the FCC and the Commission under and with respect to the Act.  Currently, court
and regulatory proceedings affecting the subject matter of this Agreement are in
various stages, including the proceedings where certain of the rules and
regulations of the FCC are being challenged    In addition, there is uncertainty
in the aftermath of the Supreme Court's decision in AT&T Corp, et al. v. Iowa
Utilities Board.  Based on that uncertainty, and the regulatory and judicial
proceedings which will occur as a result of that decision, the Parties
acknowledge that this Agreement may need to be changed to reflect any changes in
law. The Agreement has not been corrected to reflect the requirements, claims or
outcomes of any of the Proceedings, although the pricing does reflect the
Commission's most current generic order, if any.  Accordingly, when a final,
decision or decisions are made in the Proceedings that automatically change and
modify the Underlying Agreement, then like changes and modifications will
similarly be made to this Agreement.  In addition, to the extent rules or laws
are based on regulatory or judicial proceedings as a result of the recent
Supreme Court decision, this Agreement will be amended to incorporate such
changes.

iv)  Subsequent to the execution of this Agreement, the FCC or the Commission
may issue decisions or orders that change or modify the rules and regulations
governing implementing of the Act.  If such changes or modifications alter the
state of the law upon which the Underlying Agreement was negotiated and agreed,
and it reasonably appears that the parties to the Underlying Agreement would
have negotiated and agreed to different term(s) condition(s) or covenant(s) than
as contained in the Underlying Agreement had such change or modification been in
existence before execution of the Underlying Agreement, then this Agreement
shall be amended to reflect such different terms(s), condition(s), or
covenant(s).  Where the parties fail to agree upon such an amendment, it shall
be resolved in accordance with the Dispute Resolution provision of this
Agreement.

                                                                         Page 95

equipment within the Premises (as defined herein) and connect with USWC; and

  NOW THEREFORE, in consideration of the mutual agreements and covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, USWC and the Interconnector (the
"parties") agree as follows:

                              ARTICLE I - PREMISES

  1.1  Right to Use.  Subject to this Agreement, USWC grants to Interconnector
       ------------
the right to use the premises described on Exhibit C ("Premises"), attached and
incorporated herein, within real property at ___________________ in the City of
_________________, County of ___________________, State of _______________.

  1.2  Relocation.  Notwithstanding Section 1.1, in the event that it is
       ----------
necessary for the Premises to be moved within the structure in which the
Premises is located ("Physical Collocation Site") or to another USWC Physical
Collocation Site, at the Interconnector's option, the Interconnector shall move
its facilities to the new Premises.  The Interconnector shall be responsible for
the preparation of the new Premises if such relocation arises from circumstances
beyond the reasonable control of USWC, including condemnation or government
order or regulation that makes the continued occupancy of the Premises or
Physical Collocation Site impossible.  Otherwise USWC shall be responsible for
any such preparation and shall bear all costs associated with the relocation.

  If the Interconnector requests that the Premises be moved within the Physical
Collocation Site or to another USWC Physical Collocation Site, USWC shall permit
the Interconnector to relocate the Premises, subject to availability of space
and associated requirements.  The Interconnector shall be responsible for all
applicable charges associated with the move, including the reinstallation of its
equipment and facilities and the preparation of the new Premises.

  In either such event, the new Premises shall be deemed the "Premises"
hereunder and the new Physical Collocation Site (where applicable) the "Physical
Collocation Site."
<PAGE>

  1.3  The Premises.  USWC agrees, at the Interconnector's sole cost and expense
       ------------
as set forth herein, to prepare the Premises in accordance with working drawings
and specifications entitled _____________________ and date _______________,
which documents, marked Exhibit C, are attached and incorporated herein. The
preparation shall be arranged by USWC in compliance with all applicable codes,
ordinances, resolutions, regulations and laws. In return for the
Interconnector's agreement to make the payments required by Section 2.1 hereof,
USWC agrees to pursue diligently the preparation of the Premises for use by the
Interconnector.

               ARTICLE II - EFFECTIVENESS AND REGULATORY APPROVAL

  2.1  Submission to State Commission.  The Agreement is prepared as a component
       ------------------------------
of the Interconnection Agreement under Sections 251 and 252 of the
Telecommunications Act of 1996, between USWC and Pac-West Communications
Company, Inc. ("Interconnection Agreement"), and the parties intend to submit
the Agreement and other elements of the Interconnection Agreement to state
commissions for approval under the provisions of 47 U.S.C. (S) 252.  This
Agreement is conditioned upon the approval of this Agreement and the
Interconnection Agreement.  After execution of this Agreement, the parties shall
submit it and the applicable Interconnection Agreement to the State commission
in the State in which the Premises is located for approval, and shall defend the
Agreement and support any reasonable effort to have this Agreement so approved,
including the supplying of witnesses and testimony if a hearing is held.

  2.2  Failure to Receive Approval.  If this Agreement does not receive such
       ---------------------------
unqualified approval, this Agreement shall be void upon written notice of either
party to the other after such regulatory action becomes final and unappealable.
Thereafter Interconnector may request to begin negotiations again under 47
U.S.C. 251.  Alternatively, the parties may both agree to modify this Agreement
to receive such approval, but neither shall be required to agree to any
modification.  Any agreement to modify shall not waive the right of either party
to pursue any appeal of the ruling made by any reviewing regulatory commission
or to seek arbitration of any of the terms of this Agreement or any of the terms
of the Interconnection Agreement.

  2.3  Preparation Prior to Regulatory Approval.  At the written election of the
       ----------------------------------------
Interconnector, USWC shall begin preparing the Premises for the Interconnector
prior to receiving the approval required by Section 2.1 hereof.   Except as
specified in the Interconnection Agreement, the evidence of such election shall
be the delivery to USWC of a letter requesting that USWC begin preparations,
payment of 50 percent of the non-recurring charge for preparing the Premises for
use by Pac-West, and the promise of Pac-West to pay the balance of the non-
recurring charges as provided in this Agreement.  Payment to USWC of the
remaining non-recurring charges due under this Agreement shall be due one month
after the Interconnector's equipment is installed at the Premises,
interconnected with USWC and operational as described in Section 3.2 below.
Upon such an election, this Agreement shall become effective but only insofar as
to be applicable to Premises preparation.  If the Agreement does not become
fully effective as contemplated by this Article due in any part to USWC not
fulfilling its obligation under 2.1 preceding, the Interconnector shall be
entitled to a refund of all payments made to USWC for preparation.
<PAGE>

                              ARTICLE III - TERM

  3.1   Commencement Date.  This Agreement shall be a term agreement, beginning
        -----------------
on the "Commencement Date" and ending on a date five years afterwards.  The
"Commencement Date" shall be the first day after the Interconnector's equipment
becomes operational as described in Section 3.2.  At the end of the term and
unless the parties agree to an extension or a superseding arrangement, this
Agreement shall automatically convert to a month-to-month Agreement.

  3.2  Occupancy.  Unless there are unusual circumstances, USWC will notify the
       ---------
Interconnector that the Premises is ready for occupancy within five (5) days
after USWC completes preparations described in Section 2.3  The Interconnector
must place operational telecommunications equipment in the Premises and connect
with USWC's network within one hundred fifty (150) days after receipt of such
notice; provided, however, that such one hundred fifty day period shall not
begin until regulatory approval is obtained under Article II and, further, that
USWC may extend beyond the one hundred fifty days upon a demonstration by the
Interconnector of a best efforts to meet that deadline and circumstances beyond
its reasonable control that prevented the Interconnector from meeting that
deadline.  If the Interconnector fails to do so, this Agreement is terminated on
the thirtieth (30/th/) day after USWC provides to the Interconnector written
notice of such failure and the Interconnector does not place operational
telecommunications equipment in the Premises and connect with USWC's network by
such thirtieth day.  In any such event, the Interconnector shall be liable in an
amount equal to the unpaid balance of the preparation charges due.  For purposes
of this Section, the Interconnector's telecommunications equipment is considered
to be operational and interconnected when connected to USWC's network for the
purpose of providing service.

                         ARTICLE IV - PREMISES CHARGES

  4.1  Monthly Charges.  Beginning on the Commencement Date, Interconnector
       ---------------
shall pay to USWC monthly fees as specified in Exhibit A.

  4.2  Billing.  Billing for Monthly Charges shall occur on or about the 25th
       -------
day of each month, with payment due thirty (30) days from the bill date.  USWC
may change its billing date practices upon providing ninety (90) days written
notice to the Interconnector.  Each USWC bill must identify the Premises
location by CLLI and/or address and must separately identify any non-contiguous
Premises within the Physical Collocation Site.  Further, USWC must specify
separately for each Premises CLLI and/or address and for any non-contiguous
Premises each rate element individually along with the quantity purchased by the
Interconnector at that (those) Premises and the individual rate charged for each
element along with the dates for which such charges apply.  USWC shall promptly
adjust Interconnector's account in each instance of misbilling identified and
demonstrated by the Interconnector.

     4.3   Nonrecurring Charges.
           --------------------

       (a) The one-time charge for preparing the Premises for use by the
           Interconnector as well as all other one-time charges associated with
           the Interconnector's request shall be exactly as stated in Exhibit B.
<PAGE>

       (b) USWC will contract for and perform the procurement, construction and
           preparation activities underlying the Monthly Fees and Nonrecurring
           Charges, using the same or consistent practices that are used by USWC
           for other construction and preparation work performed in the Physical
           Collocation Site and shall make every possible effort to obtain all
           necessary approvals and permits, where applicable, promptly.  USWC
           will obtain more than one trade subcontractor submission to the
           extent available when the initial trade subcontractor bid, proposal
           or quotation associated with an ICB pursuant to Exhibit B exceeds
           ten-thousand dollars ($10,000.00).  It is understood and agreed that
           any such request for additional subcontractor submissions will likely
           add to the time necessary to provide physical collocation and, for
           that reason, Interconnector reserves the right to authorize USWC to
           forgo such additional bids but will only do so in writing. USWC will
           permit the Interconnector to inspect all supporting documents for the
           Monthly Fees and Nonrecurring Charges.  Any dispute regarding such
           USWC charges will be subject to the dispute resolution provisions
           hereof.  Notwithstanding the above, the Interconnector may directly
           contract with any supplier, vendor, subcontractor, or contractor that
           USWC approves for such work (including but not limited to the
           procurement and installation of cages) and may, at Interconnector's
           election, be solely responsible for any and all payments due to such
           supplier, vendor, subcontractor or contractor for such procurement,
           construction and preparation activities.  Where Interconnector
           exercises this right, Interconnector shall pay to USWC only those
           amounts associated with labor hours of USWC personnel necessary for
           such USWC personnel to observe and approve such work at the Premises
           within the Physical Collocation Site.

       (c) Nonrecurring Charges associated with the point-of-termination bay
           shall be applied to the Interconnector by USWC only where the
           Interconnector requests in writing that USWC supply such point-of-
           termination bay.  Otherwise, the Interconnector shall be responsible
           for purchasing such point-of-termination bays and for arranging their
           installation by a vendor, subcontractor or contractor approved by
           USWC to perform such work.

  4.4  Preparation.  USWC will begin preparation on execution of this Agreement
       -----------
and upon receipt of written notice from Interconnector as described in Section
2.3.

  4.5  Pre-Preparation Access.  USWC shall permit the Interconnector to have
       ----------------------
access to the Premises for the purpose of inspection once physical collocation
site preparation activities have begun.  Interconnector agrees to limit the
number of such inspections to three per Premises except where such inspection
exposes a non-conformance with the Interconnector's requirements as stated in
its initial request or this Agreement.

  4.6  Breach Prior to Commencement Date.  If the Interconnector materially
       ----------------------------------
breaches this Agreement by purporting to terminate this Agreement after USWC has
begun preparation of the Premises then, in addition to any other remedies that
USWC might have, the Interconnector shall be liable in the amount equal to the
non-recoverable costs less estimated net salvage.  Non-recoverable costs include
the non-recoverable cost of equipment and material ordered, provided or used;
subcontractor charges paid by USWC for work performed
<PAGE>

on behalf of Interconnector; the non-recoverable cost of installation and
removal, including the costs of equipment and material ordered, provided and
used; labor for work done on behalf of Interconnector for preparation;
transportation and any other associated costs. USWC shall provide Interconnector
with a detailed invoice showing the costs it incurred associated with
preparation. Further, at the Interconnector's election, USWC shall provide to
the Interconnector all materials that it determined to be unsalvageable. Should
the costs incurred by USWC be used for the provision of a collocation
arrangement for a third party, such costs shall be refunded to the
Interconnector.

  4.7  Space Preparation Fee True-Up.  For all work performed by USWC and by
       -----------------------------
vendors, subcontractors and contractors hired by USWC in order to prepare the
Premises pursuant to the Interconnector's written request and pursuant to 4.3
preceding, USWC shall within ninety (90) days of the completion of the Premises
preparation work perform a true-up of all USWC, vendor, subcontractor and
contractor bill amounts associated with any ICB pricing performed pursuant to
Exhibit B.  If the resulting total cost is less than that paid by the
Interconnector, then USWC shall within thirty (30) days refund to the
Interconnector the difference between the actual cost and the payment that the
Interconnector had previously submitted to USWC.  Alternatively, if the total
cost exceeds that previously paid by the Interconnector, then the Interconnector
shall submit payment to USWC for the difference within thirty (30) days for its
receipt of the bill for such an amount.  Nothing in either case releases USWC
from its obligation to make best-faith efforts to achieve the lowest-available
cost for the preparation work that it proves is necessary or releases USWC from
its obligation to allow the Interconnector to inspect such documents pursuant to
4.3 preceding.

                      ARTICLE V - INTERCONNECTION CHARGES

  Charges for interconnection and collocation shall be set forth in Exhibits A
and B.

                        ARTICLE VI - DEMARCATION POINT

  6.1  Cable Entrances.  The Interconnector shall use a dielectric fiber optic
       ----------------
cable as a transmission medium to the Premises, or other transmission media as
it determines is necessary in order to provide services for which it has legal
and regulatory authority.  The Interconnector shall be permitted at least two
(2) cable entrance routes into the Premises whenever two entrance routes are
used by USWC at that Physical Collocation Site.

  6.2  Demarcation Point.  USWC and the Interconnector shall designate the
       -----------------
point(s) of interconnection within the Physical Collocation Site as the point(s)
of physical demarcation between the Interconnector's network and USWC's network,
with each being responsible for maintenance and other ownership obligations and
responsibilities on its side of that demarcation point.  USWC and the
Interconnector anticipate that the demarcation point will be within the point-
of-termination bay which the Interconnector may elect to provide and install
pursuant to 4.3 preceding.  Where no point of termination bay is elected by the
Interconnector, the point(s) of interconnection shall be specified in Exhibit D.
<PAGE>

                         ARTICLE VII - USE OF PREMISES


  7.1  Nature of Use.  The Premises are to be used by the Interconnector for
       --------------
purposes of locating equipment and facilities within USWC's Physical Collocation
Sites to connect with USWC services or facilities and other Interconnectors.
USWC shall permit Interconnector to place, maintain and operate on Premises any
equipment, pursuant to the FCC's regulations on the types of equipment required
to be collocated.  Consistent with the nature of the Premises and the
environment of the Premises, the Interconnector shall not use the Premises for
office, retail, or sales purposes.  No signs or marking of any kind by the
Interconnector shall be permitted on the Premises or on the grounds surrounding
the Premises.

  7.2  Administrative Uses.  The Interconnector may use the Premises for
       --------------------
placement of equipment and facilities only.  The Interconnector's employees,
agents and contractors shall be permitted access to the Premises at all
reasonable times, provided that the Interconnector's employees, agent and
contractors comply with USWC's policies and practices pertaining to fire, safety
and security.  The Interconnector agrees to comply promptly with all laws,
ordinances and regulations affecting the use of the Premises.  Upon the
expiration of the Agreement, the Interconnector shall surrender the Premises to
USWC in the same condition as when first occupied by the Interconnector except
for ordinary wear and tear.

  7.3  Threat to Network or Facilities.  Interconnector equipment or operating
       --------------------------------
practices representing a significant demonstrable technical threat to USWC's
network or facilities, including the Premises, are strictly prohibited.

  7.4  Interference or Impairment.  Notwithstanding any other provision hereof,
       ---------------------------
the characteristics and methods of operation of any equipment or facilities
placed in the Premises shall not interfere with or impair service over any
facilities of USWC or the facilities of any other person or entity located in
the Physical Collocation Site; create hazards for or cause damage to those
facilities, the Premises, or the Physical Collocation Site; impair the privacy
of any communications carried in, from, or through the Physical Collocation
Site; or create hazards or cause physical harm to any individual or the public.
Any of the foregoing events would be a material breach of this Agreement if,
after USWC's submission to Interconnector of written notice of such interference
or impairment, Interconnector did not promptly work to eliminate the
interference or impairment.

  7.5  Interconnection to Others.  The Interconnector may directly connect to
       --------------------------
other Interconnectors' facilities within the Physical Collocation Site.  USWC
agrees to provide to Interconnector, upon its receipt of the Interconnector's
written request, any facilities necessary for such interconnection wherever such
facilities exist or can be made available and USWC shall provide any such
facilities pursuant to 4.3 preceding and Exhibits A and B.  Further, USWC agrees
to provide to the Interconnector, upon its receipt of the Interconnector's
written request, unbundled network transmission elements at rates specified in
Exhibits A and B, and USWC will facilitate interconnection of the
Interconnector's collocation equipment to other services offered in USWC's
tariffs or other Agreements (e.g., Synchronous Service Transport service).  For
the purposes of Interconnection to Others, where the other Interconnector's
Interconnection Agreement differs from this Agreement, the less restrictive
terms and conditions relating to such direct interconnection and the lower
charges identified in the two
<PAGE>

Agreements for such direct interconnection shall apply to both Interconnectors
for all Interconnection between those two Interconnectors. Interconnector agrees
to continue to pay to USWC all applicable Monthly Charges for space, power and
for all other interconnection circuits at the Premises.

  7.6  Personality and its Removal.  Subject to the Article, the Interconnector
       ----------------------------
may place or install in or on the Premises such fixtures and equipment as it
shall deem desirable for the conduct of business.  Personal property, fixtures
and equipment placed by the Interconnector in 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 personality and may be removed by
Interconnector at any time.  Any damage caused to the Premises by the removal of
such property shall be promptly repaired by Interconnector at its expense.

  7.7  Alterations  In no case shall the Interconnector or any person purporting
       -----------
to be acting through on or behalf of the Interconnector make any rearrangement,
modification, improvement, addition, repair, or other alteration to the Premises
or the Physical Collocation Site without the advance written permission and
direction of USWC.  USWC shall make best efforts to honor any reasonable request
for a modification, improvement, addition, repair, or other alteration proposed
by the Interconnector, provided that USWC shall have the right to, for reasons
that it specifies in writing, reject or modify any such request except as
required by state or federal regulators.  The cost of any such specialized
alterations shall be paid by Interconnector in accordance with the terms and
conditions identified in Article IV herein.

                           ARTICLE VIII - STANDARDS

  8  Minimum Standards.  This Agreement and the physical collocation provided
     ------------------
hereunder is made available subject to and in accordance with the (i) Bellcore
Network Equipment Premises System (NEBS) Generic Requirements (GR-63-CORE and
GR-1089-CORE), as may be amended at any time and from time to time, and any
successor documents, except to the extent that USWC deviates from any such
requirements for its equipment and the facilities and services that it uses and
provides or to the extent that USWC allows other Interconnectors to deviate from
any such requirements; and, (ii) any statutory and/or regulatory requirements in
effect at the execution of this Agreement or that subsequently become effective
and then when effective.  The Interconnector shall strictly observe and abide by
each.  USWC shall publish and provide to the Interconnector its Reference
Handbook for Collocation to provide Interconnector with guidelines and USWC's
standard operating practices for collocation.  USWC agrees that the material
terms and conditions of collocation are not contained in such a technical
publication, nor can USWC change the terms and conditions of this Agreement by
changing that technical publication; however, any revision made to address
situations potentially harmful to USWC's network or the Premises or Physical
Collocation Site, or to comply with statutory and/or regulatory requirements
shall become effective immediately and the Interconnector agrees to take steps
to comply with such revisions immediately upon its receipt of USWC's written
notification of the change.

provided cable to the Premises.  In the alternative, at the Interconnector's
option, USWC shall provide interconnection facilities, i.e., unbundled network
transmission elements, from an Interconnector-designated location (e.g., the
Interconnector's Node) to the Premises within the Physical Collocation Site.
Nothing in this paragraph shall preclude the Interconnector from obtaining
unbundled network transmission elements from USWC at any Premises within a
Physical Collocation Site for primary or redundant interconnection.

  9.4  Regeneration.  Regeneration on intra-building connections will be
       -------------
provided by USWC, when requested.  The price for regeneration shall be pursuant
to Exhibit B.

  9.5  Removal.  The Interconnector is responsible for removing any equipment,
       --------
property or other items that it brings into the Premises or any other part of

breaker restoration, to the extent that such fuses and circuit breakers are not
controlled by USWC and only if and as required; and
  (e)  the connection cable and associated equipment which may be required
within the Premises to the point(s) of interconnection. USWC does not assume any
such responsibility unless contracted to perform such work on behalf of the
Interconnector.
<PAGE>

  9.7  Verbal Notifications Required.  The Interconnector is responsible for
       ------------------------------
immediate verbal notification to USWC of significant outages or operations
problems which could impact or degrade USWC's network, switches, or services,
and for providing an estimated clearing time for restoration.  In addition,
written notification must be provided within twenty-four (24) hours.  Likewise,
USWC is responsible for providing immediate verbal notification to the
Interconnector of problems with USWC's network or operations which could impact
or degrade Interconnector's network, switches, or services, and provide an
estimated clearing time for restoration.  Further, USWC shall provide written

For the purposes of this paragraph, written notification may be given by
electronic mail so long as the notifying party provide the required verbal
notification to the other.

  9.8  Service Coordination.  The Interconnector is responsible for coordinating
       ---------------------
with USWC to ensure that services are installed in accordance with the service
request.  Likewise, USWC is obligated to coordinate with Interconnector to
ensure the services are installed in accordance with the service request and
fulfill the service request in a timely, effective manner.

  9.9  Testing.  The Interconnector is responsible for testing, to identify and
       --------
clear a trouble when the trouble has been isolated to an Interconnector-provided
facility or piece of equipment.  If USWC testing is also required, it will be
promptly provided as part of its obligation to provide to Interconnector network
interconnection.

                          ARTICLE X - QUIET ENJOYMENT

  Subject to the other provisions hereof, USWC covenants that it has full right
and authority to permit the use of the Premises by the Interconnector and that,
so long as the Interconnector performs all of its obligations herein, the
Interconnector may peaceably and quietly enjoy the Premises during the term
hereof.

                            ARTICLE XI - ASSIGNMENT

  The Interconnector shall not assign or otherwise transfer this Agreement,
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 USWC.  Any
purported assignment or transfer made without such consent may be made void by
USWC at its option.

                          ARTICLE XII - CASUALTY LOSS

  12.1  Damage to Premises.  If the Premises are damaged by fire or other
        -------------------
casualty, and

     (i)   the Premises are not rendered untenantable in whole or in part, USWC
           shall repair the same at its expense (as hereafter limited) and the
           Monthly Charges shall not be abated, or

     (ii)  the Premises are rendered untenantable in whole or in part and such
           damage or destruction can be repaired within ninety (90) days, USWC
           has the option to repair the Premises at its expense (as hereafter
           limited) and all Monthly Charges
<PAGE>

           shall be proportionately abated while Interconnector was deprived of
           the use and the interconnection. If the Premises cannot be repaired
           within ninety (90) days, or USWC opts not to rebuild, then this
           Agreement shall (upon notice to the Interconnector within thirty (30)
           days following such occurrence) terminate as of the date of such
           damage. However, USWC must provide to Interconnector comparable
           substitute interconnection and collocation arrangements at another
           mutually-agreeable Physical Collocation Site without penalty or
           nonrecurring charges assessed against the Interconnector.

Any obligation on the part of USWC to repair the Premises shall be limited to
repairing, restoring and rebuilding the Premises as originally prepared for the
Interconnector and shall not include any obligation to repair, restore, rebuild
or replace any alterations or improvements made by the Interconnector or by USWC
on request of the Interconnector; or any fixture or other equipment installed in
the Premises by the Interconnector or by USWC on request of the Interconnector.

  12.2  Damage to Premises.  In the event that the Premises shall be so damaged
        -------------------
by fire or other casualty that closing, demolition or substantial alteration or
reconstruction thereof shall, in USWC's opinion, be advisable, then,
notwithstanding that the Premises may be unaffected thereby, USWC, at its
option, may terminate this Agreement by giving the Interconnector ten (10) days
prior written notice within thirty (30) days following the date of such
occurrence.


                    ARTICLE XIII - LIMITATION OF LIABILITY

  14.1  Limitation.  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 USWC, if any shall be as described in the Interconnection
Agreement in effect between the parties.

  Each party shall be indemnified and held harmless by the other against claims
and damages by any third party arising from provision of the other party's
services or equipment except those claims and damages directly associated with
the provision of services to the other party which are governed by the
provisioning party's applicable tariffs.

  Neither party shall have any liability whatsoever to the customers of the
other party for claims arising from the provision of the other party's service
to its customers, including claims for interruption of service, quality of
service or billing disputes.

  The liability of either party for its willful misconduct, if any, is not
limited by this Agreement.

space adjacent to the Premises and/or with access to the outside of the
Premises; and that any in-place optional cage around the Premises is a permeable
boundary that will not prevent the Others from observing or even damaging the
Interconnector's equipment and facilities.  In addition to any other applicable
limitation, USWC

                     [LETTERHEAD OF GTE NETWORK SERVICES]


February 3, 2000



Mr. John Sumpter
Pac-West Telecomm, Inc.
4210 Coronado Avenue
Stockton, CA 95204


Dear Mr. Sumpter:

GTE has received your letter stating that, under Section 252(i) of the
Telecommunications Act of 1996, Pac-West Telecomm, Inc. ("Pac-West") wishes to
adopt the terms of the arbitrated Interconnection Agreement between Electric
Lightwave Incorporated ("ELI") and GTE that was approved by the Commission as an
effective agreement in the State of Oregon in Docket No. ARB 91 (Terms)/1/. I
understand you have a copy of the Terms.

Please be advised that GTE's position regarding the adoption of the Terms is as
follows.

     On January 25, 1999, the Supreme Court of the United States ("Court")
issued its decision on the appeals of the Eighth Circuit's decision in Iowa
Utilities Board. Specifically, the Supreme Court vacated Rule 51.319 of the
FCC's First Report and Order, FCC 96-325, 61 Fed. Reg. 45476 (1996) and modified
several of the FCC's and the Eighth Circuit's rulings regarding unbundled
network elements and pricing requirements under the Act. AT&T Corp. v. Iowa
Utilities Board, No. 97-826, 1999 U.S. LEXIS 903 (1999).

     Three aspects of the Court's decision are worth noting. First, the Court
upheld on statutory grounds the FCC's jurisdiction to establish rules
implementing the pricing provisions of the Act. The Court, though, did not
address the substantive validity of the FCC's pricing rules. This issue will be
decided by the Eighth Circuit on remand. GTE contends that certain provisions of
the Terms may be void or unenforceable as a result of the Court's decision of
January 25, 1999 and the remand of the pricing rules to the United States Eighth
Circuit Court of Appeals.


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

1  *These "agreements" are not agreements in the generally accepted
understanding of that term. GTE was required to accept these agreements, which
were required to reflect the then-effective FCC rules.













<PAGE>

February 3, 2000
Page 2


     Second, the Court held that the FCC, in requiring ILECs to make available
all UNEs, had failed to implement section 251(d)(2) of the Act, which requires
the FCC to apply a "necessary" or "impair" standard in determining the network
elements ILECs must unbundle. The Court ruled that the FCC had improperly failed
to consider the availability of alternatives outside the ILEC's network and had
improperly assumed that a mere increase in cost or decrease in quality would
suffice to require that the ILEC provide the UNE. The Court therefore vacated in
its entirety the FCC rule setting forth the UNEs that the ILEC is to provide.
The FCC must now promulgate new UNE rules that comply with the Act/2/. As a
result, any provisions in the Terms requiring GTE to provide UNEs are nullified.

     Third, the Court upheld the FCC rule forbidding ILECs from separating
elements that are already combined (Rule 315(b)), but explained that its remand
of Rule 319 "may render the incumbents' concern on [sham unbundling] academic."
In other words, the Court recognized that ILEC concerns over UNE platforms could
be mooted if ILECs are not required to provide all network elements: "If the FCC
on remand makes fewer network elements unconditionally available through the
unbundling requirement, an entrant will no longer be able to lease every
component of the network."

     The Terms which Pac-West seeks to adopt does not reflect the Court's
decision, and any provision in the Terms that is inconsistent with the decision
is nullified.

   GTE anticipates that after the FCC issues new final rules on UNEs, this
matter may be resolved. In the interim, GTE would prefer not to engage in the
arduous task of reforming agreements to properly reflect the current status of
the law and then to repeat the same process later after the new FCC rules are in
place. Without waiving any rights, GTE proposes that the parties agree to hold
off amending (or incorporating the impact of the decision into) the Terms and
let the section 252(i) adoption proceed by maintaining the status quo until
final new FCC rules are implemented (the "New Rules"), subject to the following
package of interdependent terms:

1. GTE will continue to provide all UNEs called for under the Terms until the
   FCC issues the New Rules even though it is not legally obligated to do so.

2. Likewise, Pac-West agrees not to seek UNE "platforms," or "already bundled"
   combinations of UNEs.

3. If the FCC does not issue New Rules prior to the expiration of the initial
   term of the Terms, GTE will agree to extend any new interconnection
   arrangement between the parties to the terms of this proposal until the FCC
   issues its New Rules.


- -------------------------
2 * On November 5, 1999, the FCC released an order regarding a new list of UNEs
that ILECs must offer to CLECs. At this time, the order is still not effective.
GTE will comply with the requirements of this order when it becomes effective.
Notwithstanding this, GTE does not waive, and hereby expressly reserves the
right to challenge the legality of this order.

4.   By making this proposal (and by agreeing to any settlement or contract
     modifications that reflect this proposal), GTE does not waive any of its
     rights, including its rights to seek recovery of its actual costs and a
     sufficient, explicit universal service fund. Nor does GTE waive its
     position that, under the Court's decision, it is not required to provide
     UNEs unconditionally. Moreover, GTE does not agree that the UNE rates set
     forth in any agreement are just and reasonable and in accordance with the
     requirements of sections 251 and 252 of Title 47 of the United States Code.

In sum, GTE's proposal as described above would maintain the status quo until
the legal landscape is settled.

Pac-West's adoption of the ELI arbitrated Terms shall become effective upon
filing of this letter with the Oregon Public Utility Commission and remain in
effect no longer than the date the ELI arbitrated Terms are terminated. The ELI
arbitrated agreement is currently scheduled to expire on June 22, 2001.

As these Terms are being adopted by you pursuant to your statutory rights under
section 252(i), GTE does not provide the Terms to you as either a voluntary or
negotiated agreement. The filing and performance by GTE of the Terms does not in
any way constitute a waiver by GTE of its position as to the illegality or
unreasonableness of the Terms or a portion thereof, not does it constitute a
waiver by GTE of all rights and remedies it may have to seek review of the
Terms, or to petition the Commission, other administrative body, or court for
reconsideration or reversal of any determination made by the Commission pursuant
to arbitration in Docket No. ARB 91, or to seek review in any way of any
provisions included in these Terms as a result of Pac-West's 252(i) election.

Nothing herein shall be construed as or is intended to be a concession or
admission by either GTE or Pac-West that any contractual provision required by
the Commission in Docket No. ARB 91 (the ELI arbitration) or any provision in
the Terms complies with the rights and duties imposed by the Telecommunications
Act of 1996, the decision of the FCC and the Commissions, the decisions of the
courts, or other laws, and both GTE and Pac-West expressly reserve their full
right to assert and pursue claims arising from or related to the Terms. In
particular, GTE does not waive and hereby expressly reserves its rights to
challenge the Commission's determination to require reciprocal compensation or
payment as local traffic from GTE to the telecommunications carrier for the
delivery of traffic to the Internet.

Should Pac-West attempt to apply such conflicting provisions, GTE reserves its
rights to seek appropriate legal and/or equitable relief. Should any provision
of the Terms be modified, such modification would likewise automatically apply
to this 252(i) adoption.

Pac-West does not concur with GTE's position as stated above; nor does Pac-West
waive any right it may have to reciprocal compensation for internet traffic.
Please indicate by your countersignature on this letter your understanding and
commitment to the following three points only:

     (A)  Pac-West adopts the Terms of the ELI arbitrated agreement for
          interconnection with GTE and in applying the Terms, agrees that Pac-
          West be substituted in place of ELI in the Terms wherever
          appropriate.

     (B)  Pac-West requests that notice to Pac-West as may be required under the
          Terms shall be provided as follows:

               To:  Pac-West Telecomm, Inc.
                    Attention: Mr. John Sumpter
                    4210 Coronado Avenue

                    Facsimile number: 209/926-4585

     (C)  Pac-West represents and warrants that it is a certified provider of
local dialtone service in the State of Oregon, and that its adoption of the
Terms will cover services in the State of Oregon only.


Sincerely,

GTE Northwest Incorporated

Vancouver, Washington 98662 (GTE and ELI being referred to collectively as the
"Parties" and individually as a "Party").  This Agreement covers services in the
state of Oregon only (the "State").

     WHEREAS, interconnection between competing Local Exchange Carriers ("LECs")
is necessary and desirable for the mutual exchange and termination of traffic
originating on each LEC's network; and

     WHEREAS, the Parties desire to exchange such traffic and related signaling
in a technically and economically efficient manner at defined interconnection
points; and

     WHEREAS, the Parties wish to enter into an agreement to interconnect their

                                   ARTICLE I
                         SCOPE AND INTENT OF AGREEMENT


Pursuant to this Agreement, the Parties will extend certain arrangements to one
another within each area in which they both operate within the State for
purposes of interconnection and the exchange of traffic between their respective
networks and access to poles, ducts, conduits and rights-of-way.  This Agreement
also governs the purchase by ELI of certain telecommunications services provided
by GTE in those service areas where GTE is the "incumbent local exchange
carrier" in accordance with Section 251(h) of the Act for resale by ELI, the
purchase by ELI of certain unbundled network elements from GTE, and the terms
and conditions of the collocation of certain equipment of ELI in the premises of
GTE.  This Agreement is an integrated package that reflects a balancing of
interests critical to the Parties.  This Agreement will be submitted to the
Oregon Public Utility Commission for approval.  The Parties agree that their
entrance into this Agreement is without prejudice to and does not waive any
positions they may have taken previously, or may take in the future, in any
legislative, regulatory, judicial or other public forum addressing any matters,
including matters related to the same types of arrangements and/or matters
related to GTE's cost recovery covered in this Agreement.  ELI agrees to
negotiate nondiscriminatory terms and conditions for the provision of services
and facilities to GTE.  GTE's execution of this Agreement is not a concession or
waiver in any manner concerning its position that certain of the rates, terms
and conditions contained herein are unlawful, illegal and improper.

The services and facilities to be provided to ELI by GTE in satisfaction of this
Agreement may be provided pursuant to GTE tariffs and then current practices.
Should such services and facilities be modified by tariff or by Order, including
any modifications resulting from other Commission proceedings, federal court
review or other final judicial action, such modifications will be deemed to
automatically supersede any rates and terms and conditions of this Agreement.
GTE will provide notification to ELI before such a tariff becomes effective, and
ELI may provide input on such proposed tariff.  The Parties shall cooperate with
one another for the purpose of incorporating required modifications into this
agreement.

      employees of a common bureau serving a group of such entities.

1.64. "Rate Center" means the specific geographic point and corresponding
      geographic area that are associated with one or more particular NPA-NXX
      Codes that have been assigned to a LEC for its provision of Exchange
      Services. The geographic point is identified by a specific Vertical and
      Horizontal ("V&H") coordinate that is used to calculate distance-sensitive
      end user traffic to/from the particular NPA-NXXs associated with the
      specific Rate Center.

1.65. "Right-of-way" ("ROW") means the right to use the land or other property
      of another party to place poles, conduits, cables, other structures and

      use discrete space in buildings, building complexes, or other locations.

1.66. "Routing Point" denotes a location that a LEC has designated on its
      network as the homing (routing) point for traffic that terminates to
      Exchange Services provided by the LEC that bear a certain NPA-NXX
      designation. The Routing Point is used to calculate airline mileage for
      the distance-sensitive transport element charges of Switched Access
      Services. Pursuant to Bellcore Practice BR795-100-100, the Routing Point
      may be an end office location, or a "LEC Consortium Point of
      Interconnection." The Routing Point must be in the same LATA as the
      associated NPA-NXX.

1.67. "Service Control Point" ("SCP") is the node in the signaling network to
      which informational requests for service handling, such as routing, are
      directed and processed. The SCP is a real time database system that, based
      on a query from the SSP, performs subscriber or application-specific
      service logic, and then sends instructions back to the SSP on how to
      continue call processing.

1.68. "Service Switching Point" ("SSP") means a Signaling Point that can launch
      queries to databases and receive/interpret responses used to provide
      specific customer services.

1.69. "Shared Transport" means the physical interoffice facility, not dedicated
      to any one customer, that is used to transport a call between switching
      offices. A central office switch translates the end user dialed digits and
      routes the call over a Common Transport Trunk Group that rides interoffice
      transmission facilities. These trunk groups and the associated interoffice
      transmission facilities are accessible by any end user (GTE end user or
      ELI end user when ELI has purchased unbundled switching), and are referred
      to as "shared transport facilities."

      the CCS network, based upon American National Standards Institute ("ANSI")
      standards.

1.72. "Signal Transfer Point" ("STP") means a packet switch in the CCS network
      that is used to route signaling messages among SSPs, SCPs and other STPs
      in order to set up calls and to query databases for advanced services.
      GTE's network includes mated pairs of local and regional STPs. STPs are
      provided in pairs for redundancy. GTE STPs conform to ANSI T1.111-8
      standards.

1.73. "Subsidiary" of a Party means a corporation or other legal entity that is
      majority owned by such Party.

      of the origination or termination of traffic to or from Exchange Service
      customers in a given area pursuant to a switched access tariff. Switched
      Access Services include: Feature Group A, Feature Group B, Feature Group
      C, Feature Group D, 800 access and 900 access services.

1.76. "Telecommunications Services" means the offering of telecommunications for
      a fee directly to the public, or to such classes of users as to be
      effectively available directly to the public, regardless of the facilities
      used.

1.77. "Third Party Contamination" means environmental pollution that is not
      generated by the LEC or CLEC but results from off-site activities
      impacting a facility.

1.78. "Trunk Side" refers to a central office switch connection that is capable
      of, and has been programmed to treat the circuit as, connecting to another
      switching entity, for example, to another central office switch. Trunk
      side connections offer those transmission and signaling features
      appropriate for the connection of switching entities and cannot be used
      for the direct connection of ordinary telephone station sets.

1.79. "Unbundled Network Elements" ("UNEs") generally means a facility or
      equipment used in the provision of a Telecommunications Service. Specific
      references to UNEs contained throughout this Agreement shall be to the
      network elements that are to be unbundled pursuant to Article VII of this
      Agreement. Such UNEs shall include the features, functions, and
      capabilities that are provided by means of such facility or equipment,

           Information received in confidence from the Source, or that is
           required to be disclosed pursuant to subpoena or other process issued
           by a court or administrative agency having appropriate jurisdiction,
           provided, however, that the recipient shall give prior notice to the
           Source and shall reasonably cooperate if the Source deems it
           necessary to seek protective arrangements.

     11.4  Survival.  The obligation of confidentiality and use with respect to
           --------
           Confidential Information disclosed by one Party to the other shall
           survive any termination of this Agreement for a period of three (3)
           years from the date of the initial disclosure of the Confidential
           Information.
                                     III-5
<PAGE>

12.  Consent.  Where consent, approval, or mutual agreement is required of a
     -------
     Party, it shall not be unreasonably withheld or delayed.

13.  Cooperation on Fraud Minimization.  Each Party assumes responsibility for
     ---------------------------------
     all fraud associated with its end user customers and accounts.  Neither
     Party shall have responsibility for, or be required to investigate or make
     adjustments to the other Party's account in cases of fraud.  The Parties
     agree that they shall cooperate with one another to resolve cases of fraud.
     The Parties' fraud minimization procedures are to be cost effective and
     implemented so as not to unduly burden or harm one Party as compared to the
     other.

14.  Dispute Resolution.
     ------------------

     14.1 Alternative to Litigation.  Except as provided under Section 252 of
          -------------------------
          the Act with respect to the approval of this Agreement by the
          Commission, the Parties desire to resolve disputes arising out of or
          relating to this Agreement without litigation.  Accordingly, except
          for action seeking a temporary restraining order or an injunction
          related to the purposes of this Agreement, or suit to compel
          compliance with this dispute resolution process, the Parties agree to
          use the following alternative dispute resolution procedures as their
          preferred remedy with respect to any controversy or claim arising out
          of or relating to this Agreement or its breach; provided, however,
          that in the event the negotiations referenced in Section 14.2 below do
          not resolve the dispute within sixty (60) Business Days (or five (5)
          Business Days as provided in Section 14.4) of the initial written
          request, either Party may elect, before filing a claim or response in
          arbitration (as the case may be) to submit an otherwise arbitrable
          dispute to the Commission, the FCC, or a court of appropriate
          jurisdiction.

     14.2 Negotiations.  At the written request of a Party, each Party will
          ------------
          appoint a knowledgeable, responsible representative to meet and
          negotiate in good faith to resolve any dispute arising out of or
          relating to this Agreement.  The Parties intend that these
          negotiations be conducted by non-lawyer, business representatives.
          The location, format, frequency, duration, and conclusion of these
          discussions shall be left to the discretion of the representatives.
          Upon agreement, the representatives may utilize other alternative
          dispute resolution procedures such as mediation to assist in the
          negotiations.  Discussions and correspondence among the
          representatives for purposes of these negotiations shall be treated as
          confidential information developed for purposes of settlement, exempt
          from discovery, and shall not be admissible in the arbitration
          described below or in any lawsuit without the concurrence of all
          Parties.  Documents identified in or provided with such
          communications, which are not prepared for purposes of the
          negotiations, are not so exempted and may, if otherwise discoverable,
          be discovered or otherwise admissible, be admitted in evidence, in the
          arbitration or lawsuit.

                                     III-6
<PAGE>

     14.3  Arbitration.  Subject to Section 14.1 above, if the negotiations do
           -----------
           not resolve the dispute within sixty (60) Business Days of the
           initial written request, the dispute shall be submitted to binding
           arbitration by a single arbitrator pursuant to the Commercial
           Arbitration Rules of the American Arbitration Association except that
           the Parties may select an arbitrator outside American Arbitration
           Association rules upon mutual agreement. A Party may demand such
           arbitration in accordance with the procedures set out in those rules.
           Discovery shall be controlled by the arbitrator and shall be
           permitted to the extent set out in this section. Each Party may
           submit in writing to a Party, and that Party shall so respond to, a
           maximum of any combination of thirty-five (35) (none of which may
           have subparts) of the following: interrogatories, demands to produce
           documents, or requests for admission. Each Party is also entitled to
           take the oral deposition of one individual of another Party.
           Additional discovery may be permitted upon mutual agreement of the
           Parties. The arbitration hearing shall be commenced within sixty (60)
           Business Days of the demand for arbitration. The arbitration shall be
           held in a mutually agreeable city. The arbitrator shall control the
           scheduling so as to process the matter expeditiously. The Parties may
           submit written briefs. The arbitrator shall rule on the dispute by
           issuing a written opinion within thirty (30) Business Days after the
           close of hearings. The times specified in this section may be
           extended upon mutual agreement of the Parties or by the arbitrator
           upon a showing of good cause. Judgment upon the award rendered by the
           arbitrator may be entered in any court having jurisdiction.

     14.4  Expedited Arbitration Procedures.  If the issue to be resolved
           --------------------------------
           through the negotiations referenced in Section 14.2 directly and
           materially affects service to either Party's end user customers, then
           the period of resolution of the dispute through negotiations before
           the dispute is to be submitted to binding arbitration or other legal
           recourse as provided in Section 14.1 shall be five (5) Business Days.
           Once such a service affecting dispute is submitted to arbitration,
           the arbitration shall be conducted pursuant to the expedited
           procedures rules of the Commercial Arbitration Rules of the American
           Arbitration Association (i.e., rules 53 through 57).

     14.5  Costs.  Each Party shall bear its own costs of these procedures,
           -----
           including the costs of responding to reasonable discovery. If the
           arbitrator finds that a Party's discovery requests require the
           responding Party to undertake unreasonable or unnecessarily
           burdensome efforts or expense, the Party seeking discovery shall
           reimburse the responding Party the costs of production of documents
           in response to such requests (including search time and reproduction
           costs). The Parties shall equally split the fees of the arbitration
           and the arbitrator.

     14.6  Continuous Service.  The Parties shall continue providing services to
           ------------------
           each other during the pendency of any dispute resolution procedure,
           and the Parties shall continue to perform their obligations
           (including making payments in accordance with Article IV, Section 4)
           in accordance with this Agreement.

                                     III-7
<PAGE>

15.  Entire Agreement.  This Agreement constitutes the entire agreement of the
     ----------------
     Parties pertaining to the subject matter of this Agreement and supersedes
     all prior agreements, negotiations, proposals, and representations, whether
     written or oral, and all contemporaneous oral agreements, negotiations,
     proposals, and representations concerning such subject matter.  No
     representations, understandings, agreements, or warranties, expressed or
     implied, have been made or relied upon in the making of this Agreement
     other than those specifically set forth herein.

16.  Expenses.  Except as specifically set out in this Agreement, each Party
     --------
     shall be solely responsible for its own expenses involved in all activities
     related to the subject of this Agreement.

17.  Force Majeure.  In the event performance of this Agreement, or any
     -------------
     obligation hereunder, is either directly or indirectly prevented,
     restricted, or interfered with by reason of fire, flood, earthquake or like
     acts of God, wars, revolution, civil commotion, explosion, acts of public
     enemy, embargo, acts of the government in its sovereign capacity, labor
     difficulties, including without limitation, strikes, slowdowns, picketing,
     or boycotts, unavailability of equipment from vendor through no fault of
     the Party responsible for obtaining that equipment, changes requested by
     Customer, or any other circumstances beyond the reasonable control and
     without the fault or negligence of the Party affected, the Party affected,
     upon giving prompt notice to the other party, shall be excused from such
     performance on a day-to-day basis to the extent of such prevention,
     restriction, or interference (and the other Party shall likewise be excused
     from performance of its obligations on a day-to-day basis until the delay,
     restriction or interference has ceased); provided however, that the Party
     so affected shall use diligent efforts to avoid or remove such causes of
     nonperformance and both Parties shall proceed whenever such causes are
     removed or cease.

18.  Good Faith Performance.  In the performance of their obligations under this
     ----------------------
     Agreement, the Parties shall act in good faith.  In situations in which
     notice, consent, approval or similar action by a Party is permitted or
     required by any provision of this Agreement, such action shall not be
     unreasonably delayed, withheld or conditioned.  In addition, each Party
     shall be responsible for labor relations with its own employees.  As soon
     as practicable, a Party experiencing labor difficulties with its employees
     that either directly or indirectly are delaying or otherwise interfering
     with that Party's timely performance under this Agreement shall notify the
     other Party and shall minimize impairment of service to the other Party at
     least to the same extent that the Party minimizes impairment of service to
     its own end-user customers, affiliates, and other carriers.

19.  Governing Law.  This Agreement shall be governed by and construed in
     -------------
     accordance with the domestic laws of the state where the Services are
     provided or the facilities reside.

20.  Standard Practices. The Parties acknowledge that GTE shall be adopting some
     ------------------
     industry standard approaches and/or establishing its own standard
     approaches to various

                                     III-8
<PAGE>

     requirements hereunder applicable to CLEC industry which may be added in
     the Guide. ELI agrees that GTE may implement such approaches to satisfy any
     GTE obligations under this Agreement, to the extent that these approaches
     are otherwise consistent with this Agreement and the nondiscrimination
     requirements of the Act. GTE will provide advanced notification to ELI of
     any material changes in procedures contained in the Guide. Notification may
     be accomplished via standard industry notification processes, GTE's
     internet site, or other appropriate means. ELI may request to be included
     on a standard electronic mail distribution list to be alerted to any
     changes identified on GTE's internet site.

21.  Headings.  The headings in this Agreement are inserted for convenience and
     --------
     identification only and shall not be considered in the interpretation of
     this Agreement.

22.  Independent Contractor Relationship.  The persons who implement this
     -----------------------------------
     Agreement on behalf of each Party shall be solely that Party's employees or
     contractors and shall be under the sole and exclusive direction and control
     of that Party.  They shall not be considered employees or contractors of
     the other Party for any purpose.  Each Party shall remain an independent
     contractor with respect to the other and shall be responsible for
     compliance with all laws, rules and regulations involving, but not limited
     to, employment of labor, hours of labor, health and safety, working
     conditions and payment of wages.  Each Party shall also be responsible for
     payment of taxes, including federal, state and municipal taxes, chargeable
     or assessed with respect to its employees, such as Social Security,
     unemployment, workers' compensation, disability insurance, and federal and
     state withholding.  Each Party shall indemnify the other for any loss,
     damage, liability, claim, demand, or penalty that may be sustained by
     reason of its failure to comply with this provision.

23.  Law Enforcement Interface.
     -------------------------

     23.1  Except to the extent not available in connection with GTE's operation
           of its own business, GTE shall provide seven day a week/twenty-four
           hour a day assistance to law enforcement persons for emergency traps,
           assistance involving emergency traces and emergency information
           retrieval on customer invoked CLASS services, including, without
           limitation, call traces requested by ELI.

     23.2  GTE agrees to work jointly with ELI in security matters to support

           etc.  Charges for providing such services for ELI Customers will be
           billed to ELI.

           enforcement agencies that the end-user to be wire tapped, traced,
           etc. is an ELI Customer and shall refer them to ELI.

24.  Liability and Indemnity.
     -----------------------

                                     III-9
<PAGE>

     24.1  Indemnification.  Subject to the limitations set forth in Section
           ---------------
           24.4 of this Article III, each Party agrees to release, indemnify,
           defend, and hold harmless the other Party from all losses, claims,
           demands, damages, expenses, suits, or other actions, or any liability
           whatsoever, including, but not limited to, costs and attorney's fees,
           whether suffered, made, instituted, or asserted by any other party or
           person, for invasion of privacy, personal injury to or death of any
           person or persons, or for losses, damages, or destruction of
           property, whether or not owned by others, proximately caused by the
           indemnifying Party's negligence or willful misconduct, regardless of
           form of action. The indemnified Party agrees to notify the other
           Party promptly, in writing, of any written claims, lawsuits, or
           demands for which it is claimed that the indemnifying Party is
           responsible under this Section and to cooperate in every reasonable
           way to facilitate defense or settlement of claims. The indemnifying
           Party shall have complete control over defense of the case and over
           the terms of any proposed settlement or compromise thereof. The
           indemnifying Party shall not be liable under this Section for
           settlement by the indemnified Party or any claim, lawsuit, or demand,
           if the indemnifying Party has not approved the settlement in advance,
           unless the indemnifying Party has had the defense of the claim,
           lawsuit, or demand tendered to it in writing and has failed to assume
           such defense. In the event of such failure to assume defense, the
           indemnifying Party shall be liable for any reasonable settlement made
           by the indemnified Party without approval of the indemnifying Party.

     24.2  End User and Content-Related Claims.  Each Party agrees to release,
           -----------------------------------
           indemnify, defend, and hold harmless the other Party, its affiliates,
           and any third-party provider or operator of facilities involved in
           the provision of Services, Unbundled Network Elements or Facilities
           under this Agreement (collectively, the "Indemnified Party") from all
           losses, claims, demands, damages, expenses, suits, or other actions,
           or any liability whatsoever, including, but not limited to, costs and
           attorney's fees, suffered, made, instituted, or asserted by either
           Party's end users against an Indemnified Party arising from Services,
           Unbundled Network Elements or Facilities. Each Party further agrees
           to release, indemnify, defend, and hold harmless the Indemnified
           Party from all losses, claims, demands, damages, expenses, suits, or
           other actions, or any liability whatsoever, including, but not
           limited to, costs and attorney's fees, suffered, made, instituted, or
           asserted by any Third Party against an Indemnified Party arising from
           or in any way related to actual or alleged defamation, libel,
           slander, interference with or misappropriation of proprietary or
           creative right, or any other injury to any person or property arising
           out of content transmitted by the Indemnified Party or such Party's
           end users, or any other act or omission of the Indemnified Party or
           such Party's end users.

           ELEMENTS OR FACILITIES PROVIDED UNDER THIS AGREEMENT. PROVIDER
           DISCLAIMS, WITHOUT LIMITATION, ANY WARRANTY OR GUARANTEE OF
           MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, ARISING FROM
           COURSE OF PERFORMANCE, COURSE OF DEALING, OR FROM USAGES OF TRADE.

     24.4  Limitation of Liability.  Each Party's liability, whether in
           -----------------------
           contract, tort or otherwise, shall be limited to direct damages,
           which shall not exceed the monthly charges for the Services,
           Unbundled Network Elements or facilities for the month during which
           the claim of liability arose. Under no circumstance shall either
           Party be responsible or liable for indirect, incidental, or
           consequential damages, including, but not limited to, economic loss
           or lost business or profits, damages arising from the use or
           performance of equipment or software, or the loss of use of software
           or equipment, or any accessories attached thereto, delay, error, or
           loss of data. Should either Party provide advice, make
           recommendations, or supply other analysis related to the Services,
           unbundled network elements or facilities described in this Agreement,
           this limitation of liability shall apply to provision of such advice,
           recommendations, and analysis.

     24.5  Intellectual Property.  Neither Party shall have any obligation to
           ---------------------
           defend, indemnify or hold harmless, or acquire any license or right
           for the benefit of, or owe any other obligation or have any liability
           to, the other based on or arising from any claim, demand, or
           proceeding by any Third Party alleging or asserting that the use of
           any circuit, apparatus, or system, or the use of any software, or the
           performance of any service or method, or the provision or use of any
           facilities by either Party under this Agreement constitutes direct or
           contributory infringement, or misuse or misappropriation of any
           patent, copyright, trademark, trade secret, or any other proprietary
           or intellectual property right of any Third Party.

25.  Multiple Counterparts.  This Agreement may be executed in multiple
     ---------------------
     counterparts, each of which shall be deemed an original, but all of which
     shall together constitute but one and the same document.

26.  No Offer.  This Agreement will be effective only upon execution and
     --------
     delivery by both Parties and approval by the Commission in accordance with
     Section 252 of the Act.

27.  No Third Party Beneficiaries.  Except as may be specifically set forth in
     ----------------------------
     this Agreement, this Agreement does not provide and shall not be construed
     to provide third parties with any remedy, claim, liability, reimbursement,
     cause of action, or other right or privilege.

28.  Notices.  Any notice to a Party required or permitted under this Agreement
     -------

     29.2  Resolution.  If either Party causes an Impairment in Service, the
           ----------
           Party whose network or service is being impaired (the "Impaired
           Party") shall promptly notify the Party causing the Impairment of
           Service (the "Impairing Party") of the nature and location of the
           problem and that, unless promptly rectified, a temporary
           discontinuance of the use of any circuit, facility or equipment may
           be required. The Impairing Party and the Impaired Party agree to work
           together to attempt to promptly resolve the Impairment of Service. If
           the Impairing Party is unable to promptly remedy the Impairment of
           Service, then the Impaired Party may at its option temporarily
           discontinue the use of the affected circuit, facility or equipment.

30.  Publicity.  Any news release, public announcement, advertising, or any form
     ---------
     of publicity pertaining to this Agreement, provision of Services, Unbundled
     Network Elements or Facilities pursuant to it, or association of the
     Parties with respect to provision of the services described in this
     Agreement, for promotional or other commercial purposes shall be subject to
     prior written approval of both GTE and ELI.

31.  Regulatory Agency Control.  This Agreement shall at all times be subject to
     -------------------------
     changes, modifications, orders, and rulings by the Federal Communications
     Commission and/or the applicable state utility regulatory commission to the
     extent the substance of this Agreement is or becomes subject to the
     jurisdiction of such agency.

32.  Changes in Legal Requirements.  GTE and ELI further agree that the terms
     -----------------------------
     and conditions of this Agreement were composed in order to effectuate the
     legal requirements in effect at the time the Agreement was produced.  Any
     modifications to those requirements that subsequently may be prescribed by
     final and effective action of any federal, state, or local governmental
     authority will be deemed to automatically supersede any terms and
     conditions of this Agreement.  Notwithstanding this section, neither Party
     waives any rights it otherwise has to dispute any action taken or not taken
     by the other Party in reliance on this section 32.

33.  Effective Date.  This Agreement will be effective upon approval by the
     --------------
     Commission in accordance with Section 252 of the Act.  If this Agreement or
     changes or modifications thereto are subject to approval of a regulatory
     agency, the "effective date" of this Agreement for such purposes will be
     the date of such approval.  Such date shall become the "effective date" of
     this Agreement for all purposes, except that ELI shall not submit LSR
     orders for resold services or unbundled network elements under the rates,
     terms, and conditions of this Agreement before the tenth business day after
     the effective date of the Agreement.

34.  Regulatory Matters.  Each Party shall be responsible for obtaining and
     ------------------
     keeping in effect all their own FCC, state regulatory commission, franchise
     authority and other regulatory approvals that may be required in connection
     with the performance of its obligations under this Agreement.

                                    III-13

35.  Rule of Construction.  No rule of construction requiring interpretation
     --------------------
     against the drafting party hereof shall apply in the interpretation of this
     Agreement.

36.  Section References.  Except as otherwise specified, references within an
     ------------------
     Article of this Agreement to a Section refer to Sections within that same
     Article.

37.  Service Standards.
     -----------------

     37.1  The Parties hereby acknowledge the exchange of Performance Measures
           as described in Appendix 37A. The Performance Measures detail the
           areas of performance to be tracked and reported in accordance with
           the provision of services under the terms and conditions of this
           Agreement. The results of these Performance Measures shall be used to
           indicate the level of quality of service GTE provides to ELI. The
           service quality standards included in Appendix 37A reflect the
           standards that GTE currently makes available to all CLECs. By
           agreeing to include those standards in Appendix 37A, ELI does not
           agree that GTE's compliance with those standards necessarily
           satisfies GTE's obligations under the Act or state law, and ELI
           reserves the right to dispute whether the service quality GTE
           provides to ELI complies with the Act or state law, regardless of
           whether that service quality complies with the standards in Appendix
           37A. GTE will make available to ELI, upon request to its GTE Account
           Manager, the CLEC Aggregate report and the monthly ELI Profile report
           with comparisons in performance compiled on a monthly, rolling three-
           month and year-to-date basis. The monthly ELI Profile report will
           provide ELI specific performance data.

     37.2  Each Party may provide input to the Commission, the FCC, and various
           telecommunications industry forums defining or establishing national
           or state-specific standards for methods of quality measurement,
           reporting, and remedies. The Parties agree that the Performance
           Measures identified in Section 37.1 of this Article are provisional,
           subject to expansion by GTE and evolution within the industry. The
           Parties further agree that such Performance Measures are subject to
           further modification by final and binding orders, rules, and
           decisions of the Commission and/or FCC thereby defining or
           establishing national or state-specific standards for methods of
           quality measurement, reporting, and remedies.

     37.3  Subsequent to GTE's adoption and system implementation of applicable
           industry, Commission, or FCC standards, measurements, reporting, and
           remedies, the Parties shall implement those new and/or modified
           requirements as they continue to evolve. In doing so, the Parties
           agree that the Performance Measures identified in Section 37.1 of
           this Article shall be replaced in their entirety.

     37.4  The Parties shall notify each other of any network events that can
           result or have resulted in service interruption, blocked calls,
           and/or changes in network performance. Such notification, however,
           shall not relieve either Party of its obligations or responsibilities
           under this Agreement or applicable law.

                                    III-14
<PAGE>

38.  Severability.  If any provision of this Agreement is held by a court or
     ------------
     regulatory agency of competent jurisdiction to be unenforceable, the rest
     of the Agreement shall remain in full force and effect and shall not be
     affected unless removal of that provision results in a material change to
     this Agreement.  If a material change as described in this paragraph occurs
     as a result of final and effective action by a court or regulatory agency,
     the Parties shall negotiate in good faith for replacement language.  If
     replacement language cannot be agreed upon within a reasonable period,
     either Party may terminate this Agreement without penalty or liability for
     such termination upon written notice to the other Party.  To the extent not
     inconsistent with this section 38, the Parties' existing service
     arrangements may continue without interruption under (a) a new agreement
     voluntarily executed by the Parties; (b) standard terms and conditions
     approved and made generally effective by the Commission, if any; (c) tariff
     terms and conditions made generally available to all CLECs; or (d) any
     rights under Section 252(i) of the Act.

39.  Subcontractors.  Provider may enter into subcontracts with third parties or
     --------------
     affiliates for the performance of any of Provider's duties or obligations
     under this Agreement.

40.  Subsequent Law.  The terms and conditions of this Agreement shall be
     --------------
     subject to any and all applicable laws, rules, or regulations that
     subsequently may be prescribed by final and effective action of any
     federal, state or local governmental authority.  To the extent required by
     any such subsequently prescribed law, rule, or regulation, the Parties
     agree to modify, in writing, the affected term(s) and condition(s) of this
     Agreement to bring them into compliance with such law, rule, or regulation.

41.  Taxes.  Any federal, state or local taxes (excluding any taxes levied on
     -----
     income), fee, surcharge, or other tax-like charge imposed, or sought to be
     imposed, on or with respect to the services provided under this Agreement
     shall be borne by the Party upon which the obligation for payment is
     imposed under applicable law, even if the obligation to collect and remit
     such taxes is placed upon the other Party.  The collecting Party shall
     charge and collect from the obligated Party, and the obligated Party agrees
     to pay to the collecting Party, all applicable taxes, except to the extent
     that the obligated Party notifies the collecting Party and provides to the
     collecting Party appropriate documentation that qualifies the obligated
     Party for a full or partial exemption.  Any such taxes shall be shown as
     separate items on applicable billing documents between the Parties.  The
     obligated Party may contest the same in good faith, at its own expense, and
     shall be entitled to the benefit of any refund or recovery, provided that
     such Party shall not permit any lien to exist on any asset of the other
     Party by reason of the contest.  The collecting Party shall cooperate in
     any such contest by the other Party.  The other Party will indemnify the
     collecting Party from any sales or use taxes that may be subsequently
     levied on payments by the other Party by the collecting Party.

     41.1  Tax - A charge which is statutorily imposed by the state or local
           jurisdiction and is either (a) imposed on the seller with the seller
           having the right or responsibility to pass the charge(s) on to the
           purchaser and the seller is responsible for remitting

                                    III-15
<PAGE>

           the charge(s) to the state or local jurisdiction or (b) imposed on
           the purchaser with the seller having an obligation to collect the
           charge(s) from the purchaser and remit the charge(s) to the state or
           local jurisdiction.

           Taxes shall include but not be limited to: federal excise tax,
           state/local sales and use tax, state/local utility user tax,
           state/local telecommunication excise tax, state/local gross receipts
           tax, and local school taxes. Taxes shall not include income, income-
           like, gross receipts on the revenue of a provider, or property taxes.
           Taxes shall not include payroll withholding taxes unless specifically
           required by statute or ordinance.

     41.2  Fees/Regulatory Surcharges - A charge imposed by a regulatory
           authority, other agency, or resulting from a contractual obligation,
           in which the seller is responsible or required to collect the
           fee/surcharge from the purchaser and the seller is responsible for
           remitting the charge to the regulatory authority, other agency, or
           contracting party.

           Fees/Regulatory Surcharges shall include but not be limited to
           E911/911, E311/311, franchise fees, Lifeline, universal service,
           Telecommunications Relay Service, and Commission surcharges.

42.  Trademarks and Trade Names.  Except as specifically set out in this
     --------------------------
     Agreement, 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 any purpose whatsoever.

43.  Waiver.  The failure of either Party to insist upon the performance of any
     ------
     provision of this Agreement, or to exercise any right or privilege granted
     to it under this Agreement, shall not be construed as a waiver of such
     provision or any provisions of this Agreement, and the same shall continue
     in full force and effect.

44.  Environmental Responsibility.
     ----------------------------

     44.1  GTE and ELI agree to comply with applicable federal, state and local
           environmental and safety laws and regulations including U.S.
           Environmental Protection Agency (EPA) regulations issued under the
           Clean Air Act, Clean Water Act, Resource Conservation and Recovery
           Act, Comprehensive Environmental Response, Compensation and Liability
           Act, Superfund Amendments and Reauthorization Act and the Toxic
           Substances Control Act and OSHA regulations issued under the
           Occupational Safety and Health Act of 1970 ("EH&S Laws"). Each Party
           has the responsibility to notify the other if Compliance inspections
           occur and/or citations are issued that impact any aspect of this
           Agreement such as occurring on a LEC Facility or involving ELI
           potential employee exposure.

                                    III-16
<PAGE>

     44.2  GTE and ELI shall provide notice of known and recognized physical
           hazards or hazardous chemicals that must include providing Material
           Safety Data Sheets (MSDSs) for materials existing on site or brought
           on site to the Facility. Each Party is required to provide specific
           notice for potential imminent danger conditions which could include,
           but is not limited to, a defective utility pole or significant
           petroleum contamination in a manhole.

     44.3  GTE will make available additional environmental control or safety
           procedures for ELI to review and follow when working at a GTE
           Facility. Providing these procedures, beyond government regulatory
           Compliance requirements, is the decision of GTE. These
           practices/procedures will represent the regular work practices
           required to be followed by the employees and contractors of GTE for
           safety and environmental protection.

     44.4  Any materials brought, used or remaining at the Facility by ELI are
           owned by ELI. ELI will indemnify GTE for these materials. No
           substantial new safety or environmental hazards can be created or new
           hazardous materials can be used at a GTE Facility. ELI must
           demonstrate adequate emergency response capabilities for its
           materials used or remaining at the GTE Facility.

     44.5  If Third Party contamination is discovered at a GTE Facility, the
           Party uncovering the condition must notify the proper safety or
           environmental authorities, to the extent required under EH&S laws.
           ELI will consult with GTE prior to making the notification, unless
           the time required for prior consultation would preclude ELI from
           complying with the applicable reporting requirement. ELI must also
           notify GTE of Third Party contamination it discovers at GTE
           facilities.

     44.6  ELI should obtain and use its own environmental permits, approvals,
           or identification numbers, to the extent such permits, approvals, or
           identification numbers are required under applicable EH&S Laws. If
           the relevant regulatory authority refuses to issue a separate permit,
           approval, or identification number to ELI, then GTE's permit,
           approval, or identification number may be used, and ELI must comply
           with all of GTE's environmental practices/procedures relating to the
           activity in question, including use of environmental "best management
           practices (BMP)" and/or selection of disposition vendors and disposal
           sites in accordance with GTE's selection criteria.

     44.7  ELI visitors must comply with GTE security, fire safety, safety,
           environmental and building practices/codes including equivalent
           employee training when working in GTE facilities.

     44.8  GTE and ELI shall coordinate plans or information required to be
           submitted to government agencies, such as emergency response plans
           and community reporting. If fees are associated with filing, GTE and
           ELI must develop a cost sharing procedure.

                                    III-17
<PAGE>

     44.9  Notwithstanding Section 23, with respect to environmental
           responsibility under this Section 44, GTE and ELI shall indemnify,
           defend and hold harmless the other party from and against any claims
           (including, without limitation, Third Party claims for personal
           injury or real or personal property damage), judgments, damages
           (including direct and indirect damage, and punitive damages),
           penalties, fines, forfeitures, cost, liabilities, interest and losses
           proximately caused by the indemnifying Party's negligent or willful
           misconduct regardless of form, or in connection with the violation or
           alleged violation of any applicable requirement with respect to the
           presence or alleged presence of contamination arising out of the
           indemnifying party's acts or omissions concerning its operations at
           the Facility.

     44.10 Activities impacting safety or the environment of a Right of Way must
           be harmonized with the specific agreement and the relationship
           between GTE and the private land owner. This could include
           limitations on equipment access due to environmental conditions
           (e.g., wetland area with equipment restrictions).

45.  TBD Prices.  Numerous provisions in this Agreement and its Attachments
     ----------
     refer to pricing principles.  If a provision references prices in an
     Attachment and there are no corresponding prices in such Attachment, such
     price shall be considered "To Be Determined" ("TBD").  With respect to all
     TBD prices, prior to ELI ordering any such TBD item, the Parties shall meet
     and confer to establish a price.  If the Parties are unable to reach
     agreement on a price for such item, an interim price shall be set for such
     item that is equal to the price for the nearest analogous item for which a
     price has been established (for example, if there is not an established
     price for  a non recurring charge ("NRC") for a specific network element,
     the Parties would use the NRC for the most analogous retail service for
     which there is an established price).  Any interim prices so set shall be
     subject to modification by any subsequent decision of the Commission.  If
     an interim price is different from the rate subsequently established by the
     Commission, any underpayment shall be paid by ELI to GTE, and any
     overpayment shall be refunded by GTE to ELI, within 45 Business Days after
     the establishment of the price by the Commission.

46.  Amendment of Certain Rates, Terms, and Conditions.  The rates, terms, and
     -------------------------------------------------
     conditions in this Agreement that are specified in Attachment 46A (the
     "AT&T Terms") were taken from the GTE/ AT&T Interconnection, Resale and
     Unbundling Agreement (the AT&T Agreement) approved by the Commission in
     Order No. 99-028 in Docket No. ARB 5.  The rates, terms, and conditions not
     included in this Agreement but referenced in Attachment 46B (the "GTE
     Terms") were excluded from the AT&T Agreement by the Commission in Docket
     No. ARB 5.  GTE and ELI agree that if the "AT&T Terms" are deemed to be
     unlawful, or are stayed, enjoined or otherwise modified, in whole or in
     part, by a court or commission of competent jurisdiction, then this
     Agreement shall be deemed to have been amended accordingly, by modification
     of the "AT&T Terms" or, as appropriate, the substitution of "GTE Terms" for
     all stayed and enjoined "AT&T Terms",

                                    III-18
<PAGE>

     and such amendments shall be effective retroactive to the Effective Date of
     this Agreement.

     GTE and ELI further agree that the terms and conditions of this Agreement
     reflect certain requirements of the FCC's First Report and Order in CC
     Docket No. 96-98. The terms and conditions of this Agreement shall be
     subject to any and all actions by any court or other governmental authority
     that invalidate, stay, vacate or otherwise modify or reinstate the FCC's
     First Report and Order, in whole or in part ("Action"). To the extent
     warranted by any such Action, the Parties agree that this Agreement shall
     be deemed to have been modified accordingly as in the first paragraph of
     this Section 46. The Parties agree to immediately apply any affected terms
     and conditions, including any in other sections and articles of this
     Agreement, consistent with such Action, and within a reasonable time
     incorporate such modified terms and conditions in writing into the
     Agreement. If the "AT&T Terms" are affected by such Action and they cannot
     be applied in a manner consistent with that Action, the "GTE Terms" shall
     apply. ELI acknowledges that GTE may seek to enforce such Action before a
     commission or court of competent jurisdiction. GTE does not waive any
     position regarding the illegality or inappropriateness of the FCC's First
     Report and Order.

     The rates, terms and conditions (including rates which may be applicable
     under true-up) specified in both the "GTE Terms" and the "AT&T Terms" are
     further subject to amendment to provide for charges or rate adjustments
     resulting from future Commission or other proceedings, including but not
     limited to any generic proceeding to determine GTE's unrecovered costs
     (e.g., historic costs, contribution, undepreciated reserve deficiency, or
     similar unrecovered GTE costs (including GTE's end user surcharge), the
     establishment of a competitively neutral universal service system, or any
     appeal or other litigation.  Any amendment to the "AT&T Terms" required as
     a result of any final Commission and/or court order resolving the appeal
     of, or other litigation over, the interconnection agreement from which the
     "AT&T Terms" are derived, shall be incorporated into this Agreement
     according to the terms of that final order, including any retroactive
     application of that amendment.  The results of any future Commission or
     other proceedings shall be incorporated into this Agreement according to
     the terms of the final Commission and/or court order resolving that
     proceeding, including any retroactive application of those results.

     If the Commission (or any other commission or federal or state court) in
     reviewing this Agreement pursuant to applicable state and federal laws,
     including Section 252(e) of the Telecommunications Act of 1996, deletes or
     modifies in any way this Section 46, this entire Agreement is void and will
     not become effective, and the Parties agree to withdraw this Agreement from
     consideration by the Commission (or any other commission or federal or
     state court).  If this Agreement is voided by operation of this provision,
     the Parties agree to immediately begin negotiations for a new agreement,
     and to treat the date that this Agreement became void as the one hundredth
     (100th) calendar day from GTE's receipt of a renewed request for
     negotiations by ELI for negotiations under Section 252 of the Act.

                                  ARTICLE IV
                    GENERAL RULES GOVERNING RESOLD SERVICES
                            AND UNBUNDLED ELEMENTS


1.   General.  General regulations, terms and conditions governing rate
     -------
     applications, technical parameters, service availability, definitions and
     feature interactions, as described in the appropriate GTE intrastate local,
     toll and access tariffs, apply to retail services made available by GTE to
     ELI for resale and unbundled network elements provided by GTE to ELI, when
     appropriate, unless otherwise specified in this Agreement.  As applied to
     services or network elements offered under this Agreement, the term
     "Customer" contained in the GTE Retail Tariff shall be deemed to mean "ELI"
     as defined in this Agreement.

2.   Liability of GTE.
     ----------------

     2.1  Inapplicability of Tariff Liability.  GTE's general liability, as
          -----------------------------------
          described in the GTE Retail Tariff, does not extend to ELI's customers
          or any other Third Party.  Liability of GTE to ELI resulting from any
          and all causes arising out of services, facilities, network elements
          or any other items relating to this Agreement shall be governed by the
          liability provisions contained in this Agreement and no other
          liability whatsoever shall attach to GTE.  GTE shall be liable for the
          individual services, facilities or elements that it separately
          provides to ELI and shall not be liable for the integration of
          components combined by ELI.

     2.2  ELI Tariffs or Contracts.  GTE shall not be liable to ELI's end users
          ------------------------
          or any third parties for any indirect, special or consequential
          damages, including, but not limited to, economic loss or lost business
          or profits, whether foreseeable or not, and regardless of notification
          by ELI of the possibility of such damages and ELI shall indemnify and
          hold GTE harmless from any and all claims, demands, causes of action
          and liabilities based on any reason whatsoever from its customers as
          provided in this Agreement.  Nothing in this Agreement shall be deemed
          to create a Third Party beneficiary relationship with ELI's end users.
          To the extent practicable, ELI will include a provision in its
          tariffs, price lists, or contracts for services provided to end-users
          so limiting the liability of other LECs, like GTE, that provide
          underlying services, facilities, or network elements.

     2.3  No Liability for Errors.  GTE is liable for mistakes that appear in
          -----------------------
          GTE's listings, 911 and other information databases, or for incorrect
          referrals of end users to ELI for any ongoing ELI service, sales, or
          repair inquiries only to the extent that GTE would be liable to its
          own end-user or other carrier customers under similar circumstances.
          With respect to mistakes or incorrect referrals for which GTE would
          not otherwise be liable, ELI shall indemnify and hold GTE harmless
          from any and all claims, demands, causes of action and liabilities
          whatsoever, including costs, expenses and reasonable attorney's fees
          incurred on account thereof, by

                                     IV-1
<PAGE>

          third parties, including ELI's end users or employees. For purposes of
          the indemnity provided in this Section 2.3, mistakes and incorrect
          referrals for which GTE would not otherwise be liable shall not
          include matters arising out of the willful misconduct of GTE or its
          employees or agents.

3.   Unauthorized Changes.
     --------------------

     3.1  Procedures.  If ELI submits an order for resold services or unbundled
          ----------
          elements under this Agreement in order to provide service to an end
          user that at the time the order is submitted is obtaining its local
          services from GTE or another LEC using GTE resold services or
          unbundled elements, and the end user notifies GTE that the end user
          did not authorize ELI to provide local exchange services to the end
          user, ELI must provide GTE with confirmation in an industry-acceptable
          format of authorization from that end user within thirty (30) Business
          Days of notification  by GTE.  If ELI cannot provide such confirmation
          of authorization within such time frame, ELI must within three (3)
          Business Days thereafter:

          (a)  notify GTE to change the end user back to the LEC providing
          service to the end user before the change to ELI was made; and

          (b)  provide any end user information and billing records ELI has
          obtained relating to the end user to the LEC previously serving the
          end user; and

          (c)  notify the end user and GTE that the change back to the previous
          LEC has been made.

     Furthermore, GTE will bill ELI fifty dollars ($50.00) per affected line to
compensate GTE for switching the end user back to the original LEC.

4.   Impact of Payment of Charges on Service. ELI is solely responsible for
     ---------------------------------------
     the payment of all charges for all services, facilities and elements
     furnished under this Agreement, including, but not limited to, calls
     originated or accepted at its or its end users' service locations. If ELI
     fails to pay when due any and all charges billed to ELI under this
     Agreement, including any late payment charges (collectively, "Unpaid
     Charges"), and any or all such charges remain unpaid more than forty-five
     (45) Business Days after the due date of such Unpaid Charges excepting
     previously disputed charges for which ELI may withhold payment, GTE shall
     notify ELI in writing that it must pay all Unpaid Charges to GTE within
     seven (7) Business Days. If ELI disputes the billed charges, it shall,
     within said seven (7) day period, inform GTE in writing of which portion of
     the Unpaid Charges it disputes, including the specific details and reasons
     for the dispute, unless such reasons have been previously provided, and
     shall immediately pay to GTE all undisputed charges. If ELI and GTE are
     unable, within thirty (30) Business Days thereafter, to resolve issues
     related to the disputed charges, then either ELI or GTE may file a request
     for arbitration under Article III of this Agreement to resolve those
     issues. Upon resolution of any dispute hereunder, if ELI owes payment it
     shall make such

                                     IV-2
<PAGE>

     payment to GTE with any late payment charge under Article III, Section 7.2,
     from the original payment due date. If ELI owes no payment, but has
     previously paid GTE such disputed payment, then GTE shall credit such
     payment including any late payment charges. GTE may discontinue service to
     ELI upon failure to pay undisputed charges as provided in this Section 4,
     and shall have no liability to ELI or ELI's end users in the event of such
     disconnection.

5.   Unlawful Use of Service.  Services, facilities or unbundled elements
     -----------------------
     provided by GTE pursuant to this Agreement shall not be used by ELI or its
     end users for any purpose in violation of law.  ELI, and not GTE, shall be
     responsible to ensure that ELI and its end users' use of services,
     facilities or unbundled elements provided hereunder comply at all times
     with all applicable laws.  GTE may refuse to furnish service to ELI or may
     disconnect particular services, facilities or unbundled elements provided
     under this Agreement to ELI or, as appropriate, ELI's end user when (i) an
     order is issued by a court of competent jurisdiction finding that probable
     cause exists to believe that the use made or to be made of the service,
     facilities or unbundled elements is prohibited by law or (ii) GTE is
     notified in writing by a law enforcement agency acting within its
     jurisdiction that any facility furnished by GTE is being used or will be
     used for the purpose of transmitting or receiving gambling information in
     interstate or foreign commerce in violation of law.  Termination of service
     shall take place after reasonable notice is provided to ELI, or as ordered
     by the court.  If facilities have been physically disconnected by law
     enforcement officials at the premises where located, and if there is not
     presented to GTE the written finding of a court, then upon request of ELI
     and agreement to pay restoral of service charges and other applicable
     service charges, GTE shall promptly restore such service.

6.   Timing of Messages.  With respect to GTE resold measured rate local
     ------------------
     service(s), chargeable time begins when a connection is established between
     the calling station and the called station.  Chargeable time ends when the
     network connection is released by the switch.  Timing of messages
     applicable to GTE's Port and Local Switching element (usage sensitive
     services) will be recorded based on originating and terminating access.

7.   Procedures For Preordering, Ordering, Provisioning, Etc.  Certain
     --------------------------------------------------------
     procedures for preordering, ordering, provisioning, maintenance and billing
     and electronic interfaces to access operational support systems for many of
     these functions are described in Appendix H.
                                      ----------

8.  Letter of Authorization.
    -----------------------

     8.1  Customer Proprietary Network Information.  GTE will not release the
          ----------------------------------------
          Customer Service Record ("CSR") containing Customer Proprietary
          Network Information ("CPNI") to ELI on GTE end user customer accounts
          unless ELI first provides to GTE a written Letter of Authorization
          ("LOA"), signed by the end user customer, authorizing the release of
          such information to ELI, or if state or federal law provides
          otherwise, in accordance with such law.

                                     IV-3
<PAGE>

     8.2  Order Processing.  An LOA will be required before GTE will process an
          ----------------
          order for Services provided in cases in which the subscriber currently
          receives Exchange Service from GTE or from a local service provider
          other than ELI.  Such LOA may be a blanket LOA or such other form as
          agreed upon between GTE and ELI.

9.   Customer Contacts.  Except as otherwise provided in this Agreement or as
     -----------------
     agreed to in a separate writing by ELI, ELI shall provide the exclusive
     interface with ELI's end user customers in connection with the marketing or
     offering of ELI services.  Except as otherwise provided in this Agreement,
     in those instances in which GTE personnel are required pursuant to this
     Agreement to interface directly with ELI's end users, such personnel shall
     not identify themselves as representing GTE.  All forms, business cards or
     other business materials furnished by GTE to ELI end users shall bear no
     corporate name, logo, trademark or trade name other than ELI's.  In no
     event shall GTE personnel acting on behalf of ELI pursuant to this
     Agreement provide information to ELI end users about GTE products or
     services.

           INTERCONNECTION AND TRANSPORT AND TERMINATION OF TRAFFIC


1.   Services Covered by This Article.
     --------------------------------

     1.1  Types of Services.  This Article governs the provision of
          -----------------
          interconnection services and facilities, meet point billing by GTE to
          ELI or by ELI to GTE and the transport and termination and billing of
          Local, IntraLATA Toll, optional EAS traffic and jointly provided
          Interexchange Carrier Access between GTE and ELI.  The services and
          facilities described in this Article shall be referred to in this
          Article V as the "Services."

2.   Billing and Rates.
     -----------------

     2.1  Rates and Charges.  Customer agrees to pay to Provider the rates and
          -----------------
          charges for the Services set forth in the applicable appendices to
          this Agreement.  GTE's rates and charges are set forth in Appendix C
                                                                    ----------
          attached to this Agreement and made a part hereof.  ELI's separate
          rates and charges are also set forth in Appendix C attached hereto and
                                                  ----------
          made a part hereof.

     2.2  Billing.  Provider shall render to Customer a bill for interconnection
          -------
          services on a current basis.  Charges for physical facilities and
          other nonusage sensitive charges shall be billed in advance, except
          for charges and credits associated with the initial or final bills.
          Usage sensitive charges, such as charges for termination of Local
          Traffic, shall be billed in arrears.  Charges for traffic that has
          been routed over a jurisdictionally inappropriate trunk group (e.g.,
          local traffic carried over trunks used for Switched Access Traffic)
          may be adjusted to reflect the appropriate compensation arrangement
          and may be handled as a post-billing adjustment to bills rendered.
          Additional matters relating to ordering, provisioning, and billing are
          included in Appendix H attached to this Agreement and made a part
                      ----------
          hereof.

     2.3  Billing Specifications.  The Parties agree that billing requirements
          ----------------------
          and outputs will be consistent with the Bellcore Output Specifications
          ("BOS").

          2.3.1  Usage Measurement.  Usage measurement for calls shall begin
                 -----------------
                 when answer supervision or equivalent SS7 message is received
                 from the terminating office and shall end at the time of call
                 disconnect by the calling or called subscriber, including time
                 released call disconnect.

          2.3.2  Minutes of Use.  Minutes of use ("MOU"), or fractions thereof,
                 --------------
                 shall not be rounded upward on a per-call basis, but will be
                 accumulated over the billing period. At the end of the billing
                 period, any remaining fraction shall be rounded up to the
                 nearest whole minute to arrive at total billable

                                      V-1
<PAGE>

                 minutes for each interconnection. MOU shall be collected and
                 measured in minutes, seconds, and tenths of seconds.

     2.4  Billing Disputes.  Disputes arising out of services and facilities
          ----------------
          provided pursuant to this Article shall be resolved according to the
          procedures established in Section 7.1 of Article III of this
          Agreement.

3.   Transport and Termination of Traffic.
     ------------------------------------

     3.1  Traffic to be Exchanged.  The Parties shall reciprocally terminate
          -----------------------
          Local, IntraLATA Toll, optional EAS, and jointly provided
          Interexchange Carrier Traffic originating on each other's networks
          utilizing either Direct or Indirect Network Interconnections as
          provided in Section 4 or Section 5 of this Article.  To this end, the
          Parties agree that there will be interoperability between their
          networks.  The Parties agree to exchange traffic associated with third
          party LECs, CLECs and Wireless Service Providers pursuant to the
          compensation arrangement specified in Section 3.3 of this Article.
          Only traffic originated by and/or terminated to a Party's or the
          Parties' end user customer(s) is to be exchanged.  In addition, the
          Parties will notify each other of any anticipated change in traffic to
          be exchanged (e.g., traffic type, volume).

     3.2  Compensation For Exchange Of Traffic.
          ------------------------------------

          3.2.1  Mutual Compensation.  The Parties shall compensate each other
                 -------------------
                 for the exchange of Local Traffic at the reciprocal rates
                 established in Appendix C. For purposes of this Agreement, GTE
                 shall compensate ELI at the tandem rate for terminating all
                 Local Traffic GTE delivers to ELI for termination; provided,
                 however, that GTE shall compensate ELI at the end office rate
                 until such time as 47 C.F.R (S) 51.711(a)(3) is reinstated. ELI
                 shall compensate GTE at the tandem rate for terminating Local
                 Traffic ELI delivers to GTE at a GTE tandem, and at the end
                 office rate for Local Traffic ELI delivers to GTE at a GTE end
                 office. Charges for the transport and termination of non-Local
                 Traffic, including optional EAS, intraLATA toll, and
                 interexchange traffic, shall be in accordance with the Parties'
                 respective intrastate or interstate access tariffs or price
                 lists, as appropriate.

          3.2.2  Bill-and-Keep.  Either Party may request that a joint traffic
                 -------------
                 study be performed no more frequently than once a quarter.
                 Should such traffic study indicate, in the aggregate, that
                 neither Party is terminating more than 60 percent of the
                 Parties' total terminated minutes for Local Traffic (referred
                 to as "Traffic Balance"), the Parties shall use a Bill-and-Keep
                 Arrangement with respect to termination of Local Traffic only,
                 which shall be implemented on the next billing cycle at least
                 ten (10) business days following notification by either Party
                 that Traffic Balance exists. Either Party may request a
                 subsequent traffic study no more frequently than once

                                      V-2
<PAGE>

                 every six months, and if such a study indicates, in the
                 aggregate, that either Party is terminating more than 60
                 percent of the Parties' total terminated minutes for Local
                 Traffic, either Party may notify the other that mutual
                 compensation as described in Section 3.2.1 shall resume on the
                 next billing cycle at least ten (10) business days following
                 that notification. Nothing in this Section 3.2.2 shall be
                 interpreted to (i) change compensation set forth in this
                 Agreement for traffic or services other than Local Traffic,
                 including but not limited to interconnection facilities, access
                 traffic or wireless traffic, or (ii) allow either Party to
                 aggregate traffic other than Local Traffic for the purpose of
                 compensation under the Bill-and-Keep Arrangement described in
                 this Section 3.2.2, except as set forth in Section 3.1 above.

     3.3  Tandem and Transit Switching Traffic.  GTE shall provide tandem
          ------------------------------------
          switching for traffic between GTE end offices subtending its tandems
          ("tandem switching"), as well as for traffic between ELI's end users
          and any Third Party that is interconnected to GTE's tandems ("transit
          tandem switching"), and ELI shall provide switching between GTE's end
          users and any Third Party that is directly interconnected with ELI's
          switch(es) ("transit switching"), as follows:

          3.3.1  The originating Party will compensate the tandem/transit
                 switching Party for each minute of originated tandem/transit
                 switched traffic that terminates to a Third Party (e.g., other
                 CLEC, ILEC, or wireless service provider). The applicable rate
                 for this charge is identified in Appendix C.
                                                  ----------

          3.3.2  The originating Party also assumes responsibility for
                 compensation to the company that terminates the call.

          3.3.3  The Parties agree to enter into their own agreements with Third
                 Parties. In the event that either Party sends traffic through
                 the other Party's network to a Third Party with whom the
                 originating Party does not have a traffic interexchange
                 agreement, the originating Party agrees to indemnify the
                 transiting Party for any termination charges rendered by the
                 Third Party for such traffic.

     3.4  Inter-Tandem Switching.  The Parties will only use inter-tandem
          ----------------------
          switching for the transport and termination of intraLATA toll traffic
          (including optional EAS) originating on each other's network at and
          after such time as ELI has agreed to and fully implemented an existing
          intraLATA toll compensation mechanism such as IntraLATA Terminating
          Access Compensation (ITAC) or a functional equivalent thereof.  The
          Parties will only use inter-tandem switching for the transport and
          termination of Local Traffic originating on each other's network at
          and after such time as the Parties have agreed to and fully
          implemented generally accepted industry signaling standards and AMA
          record standards which shall support the recognition of multiple
          tandem switching events.

                                      V-3
<PAGE>

     3.5  IntraLATA Toll Compensation Plan.  If ELI becomes an active
          --------------------------------
          participant in an existing industry intraLATA toll compensation plan,
          and GTE is also a participant in that plan, the Parties agree to use
          that compensation plan, instead of other processes that may be
          specified in this Article V, as the billing processes for switched
          access charges for intraLATA toll traffic.  This includes intraLATA
          toll traffic exchanged between the Parties, as well as intraLATA toll
          traffic originated by one Party that transits the other Party's
          network to terminate to a third party.  Until such time as the Parties
          have the capability to indentify, measure, and adjust billing records
          for this traffic when it is routed over a combined trunk group, the
          Parties agree to use a separate dedicated trunk group for this
          traffic.

4.   Direct Network Interconnection.
     ------------------------------

     4.1  Network Interconnection Architecture.  ELI may interconnect with GTE
          ------------------------------------
          at any of the Currently Available points required by the FCC or the
          Commission.  ELI may request, and GTE shall consider, interconnection
          at additional points on an individual case basis.  Interconnection
          will be as specified in the following subsections.  The installation
          timeline may vary based on the configuration, but GTE will work with
          ELI in all circumstances to install "IPs" within 120 calendar days
          absent extenuating circumstances.  Network interconnection and
          protocol must be based on industry standards developed consistent with
          the Act and applicable FCC or State requirements.

          4.1.1  Subject to mutual agreement, the Parties may use the following
                 types of network facility interconnection, using such interface
                 media as are appropriate to support the type of interconnection
                 requested.

                 (a)   A Mid-Span Fiber Meet within an existing GTE exchange
                 area whereby the Parties mutually agree to jointly plan and
                 engineer their facility "IP" at a designated manhole or
                 junction location. The "IP" is the demarcation between
                 ownership of the fiber transmission facility. Each party is
                 individually responsible for its incurred costs in establishing
                 this arrangement.

                 (b)   A Virtual or Physical EIS arrangement at a GTE wire
                 center subject to the rates, terms, and conditions contained in
                 Article IX of this Agreement and GTE's applicable tariffs.

                 (c)   A Special Access arrangement and/or CLEC Dedicated
                 Transport arrangement terminating at a GTE wire center subject
                 to the rates, terms, and conditions contained in GTE's
                 applicable tariffs. These facilities will meet the standards
                 set forth in such tariffs.

          4.1.2  Virtual and Physical EIS arrangements are governed by
                 appropriate GTE tariffs, except as provided in Article IX,
                 Section 1.3.

     4.2  Compensation.  Unless the Parties otherwise mutually agree, the
          ------------
          Parties agree to the following compensation for interconnection
          facilities, depending on facility type.

          4.2.1  Mid-Span Fiber Meet: GTE will charge special access (flat
                 rated) transport from the applicable intrastate access tariff
                 and will rate charges between the "IP" and GTE's
                 interconnection switch. Charges will be reduced to reflect the
                 proportionate share of the facility that is used for transport
                 of traffic originated by GTE. The initial proportionate share
                 factor for facilities shall be negotiated by the Parties and
                 updated quarterly in like manner or as the Parties otherwise
                 agree. ELI will charge flat rated transport to GTE for ELI
                 facilities used by GTE at the rates in ELI's tariff or price
                 list, or as mutually agreed. ELI will apply charges based on
                 the lesser of: (i) the airline mileage from the "IP" to the ELI
                 switch; or (ii) the airline mileage from the GTE switch to the
                 serving area boundary.

          4.2.2  Collocation: GTE will charge Virtual or Physical EIS rates from
                 the applicable GTE tariff. Charges for EIS cross-connect
                 facilities used to connect ELI's collocated equipment with
                 GTE's switch will be reduced to reflect the proportionate share
                 of the facility that is used for transport of traffic
                 originated by GTE. ELI will charge GTE flat rated transport at
                 the rates in ELI's tariff or price list, or as mutually agreed,
                 to reflect the proportionate share of the facility that is used
                 for transport of traffic originated by GTE. ELI will apply
                 charges based on the lesser of: (i) the airline mileage from
                 the "IP" to the ELI switch; or (ii) two (2) times the airline
                 mileage from the GTE switch to the serving area boundary.

          4.2.3  Special Access and/or CLEC Dedicated Transport: GTE will charge
                 special access and/or switched access rates from the applicable
                 GTE intrastate access tariff. Charges will be reduced to
                 reflect the proportionate share of the facility that is used
                 for transport of traffic originated by GTE. The Parties will
                 negotiate an initial factor representative of the proportionate
                 share of the facilities. This factor will be updated quarterly
                 in like manner or as the Parties otherwise agree.

     4.3  Trunking Requirements.
          ---------------------

          4.3.1  The Parties shall establish and maintain trunks over which each
                 Party shall terminate to its end users the Exchange Services,
                 Local Traffic and intraLATA toll or optional EAS traffic
                 originated by the end users of the other Party.

                                      V-5
<PAGE>

          4.3.2  The Parties agree to establish trunk groups of sufficient
                 capacity from the interconnecting facilities such that trunking
                 is available to any switching center designated by either
                 Party, including end offices, tandems, 911 routing switches,
                 and directory assistance/operator service switches. The Parties
                 will mutually agree where one-way or two-way trunking will be
                 available. The Parties may use two-way trunks for delivery of
                 local traffic or either Party may elect to provision its own
                 one-way trunks for delivery of local traffic to the other
                 Party. If a Party elects to provision its own one-way trunks,
                 that Party will be responsible for its own expenses associated
                 with the trunks.

          4.3.3  ELI and GTE shall, where applicable, make reciprocally
                 available, by mutual agreement, the required trunk groups to
                 handle different traffic types. ELI and GTE will support the
                 provisioning of trunk groups that carry combined or separate
                 Local Traffic and intraLATA toll and optional EAS traffic. The
                 Parties shall establish and maintain separate trunk groups for
                 the following: (1) to originate and terminate interLATA calls
                 when either Party is acting as an IXC and ordering switched
                 access service from the other Party; (2) to provide joint
                 Switched Access Service to IXCs; and (3) for other types of
                 traffic as the Parties mutually agree. To the extent ELI
                 desires to have any IXC originate or terminate traffic to ELI
                 using jointly provided switched access facilities routed
                 through a GTE tandem, it is the responsibility of ELI to
                 arrange for such IXC to issue an ASR to GTE to direct GTE to
                 route the traffic. If GTE does not receive an ASR from the IXC,
                 GTE will initially route the switched access traffic between
                 the IXC and ELI. If the IXC subsequently indicates that it does
                 not want the traffic routed to or from ELI, GTE will not route
                 the traffic to or from ELI.

                 4.3.3.1  Each Party agrees to route traffic only over the
                          proper jurisdictional trunk group.

                 4.3.3.2  Each Party shall only deliver traffic over the local
                          interconnection trunk groups to the other Party's
                          tandem or switch performing a tandem function for
                          those publicly-dialable NXX Codes served by end
                          offices that directly subtend the tandem or switch or
                          to those LECs or wireless service providers that
                          directly subtend the tandem or switch.

                 4.3.3.3  Neither Party shall route Switched Access Service
                          traffic over local interconnection trunks. Neither
                          Party shall route local traffic over Switched Access
                          Service trunks, except, and only to the extent
                          necessary, to remedy, avoid, or relieve significant
                          traffic blockage occurring on the proper
                          jurisdictional trunk group.

                                      V-6
<PAGE>

          4.3.4  ELI and GTE will reciprocally provide Percent Local Usage
                 ("PLU") factors to each other on a quarterly basis to identify
                 the proper jurisdiction of each call type that is carried over
                 the required trunks. If either Party does not provide to the
                 other Party an updated PLU, the previous PLU will be utilized.
                 The Parties agree to the initial PLU factor as set forth in
                 Appendix C.

          4.3.5  Reciprocal traffic exchange arrangement trunk connections shall
                 be made at a DS-1 or multiple DS-1 level, DS-3, (SONET where
                 technically available) and shall be jointly-engineered and
                 maintained to an objective P.01 grade of service.

          4.3.6  ELI and GTE agree to use diligent efforts to develop and agree
                 on a Joint Interconnection Grooming Plan prescribing standards
                 to ensure that the reciprocal traffic exchange arrangement
                 trunk groups are maintained at consistent P.01 or better grades
                 of service. Such plan shall also include mutually-agreed upon
                 default standards for the configuration of all segregated trunk
                 groups.

          4.3.7  Signaling System 7 ("SS7") Common Channel Signaling will be
                 used to the extent that such technology is available. If SS7 is
                 not available, Multi-Frequency Signaling ("MF") will be used as
                 specified.

          4.3.8  The Parties agree to offer and provide to each other B8ZS
                 Extended Superframe Format ("ESF") facilities, where available,
                 capable of voice and data traffic transmission.

          4.3.9  The Parties will support intercompany 64kbps clear channel
                 where available.

          4.3.10 Orders between the Parties to establish, add, change, or
                 disconnect trunks shall be processed by use of an Access
                 Service Request ("ASR"), or another industry standard
                 eventually adopted to replace the ASR for local service
                 ordering as referenced in Appendix H.

          4.3.11 The Parties will work together to establish high usage end-
                 office trunk groups sufficient to handle the greater of the
                 actual or reasonably forecasted traffic volumes between ELI and
                 a GTE end office.

     4.4  Network Redesigns Initiated by GTE.  GTE will not charge ELI when GTE
          ----------------------------------
          initiates its own network redesigns/reconfigurations, but GTE shall
          make best efforts to notify ELI of any GTE network
          redesigns/reconfigurations that will affect ELI's facilities
          sufficiently in advance to enable ELI to accommodate such network
          redesign/reconfiguration. The Parties shall coordinate deployment and

                                      V-7
<PAGE>

          accommodation of any such network redesigns/reconfigurations to avoid
          or minimize disruption in services provided to their end users.

     4.5  Calling Scopes for Tandem and End Office Interconnection.
          --------------------------------------------------------

          4.5.1  GTE Tandem Interconnection calling scope (originating and
                 terminating) is to those GTE end offices which subtend the GTE
                 tandem to which the connection is made except as provided for
                 in Section 3.3 of this Article.

          4.5.2  GTE End Office Interconnection calling scope (originating and
                 terminating) is only to the end office to which the connection
                 is made and its remotes.

     4.6  Trunk Forecasting.
          -----------------

          4.6.1  The Parties will work towards the development of joint
                 forecasting of trunk groups. GTE shall share with ELI the
                 applicable information necessary to facilitate the Parties'
                 joint planning and forecasing efforts. Intercompany forecast
                 information must be provided by the Parties to each other twice
                 a year. The semi-annual forecasts will include:

                 (1)  yearly forecasted trunk quantities for no less than a two-
                 year period (current year, plus one year); and

                 (2) the use of (i) CLCI-MSG codes, which are described in
                 Bellcore document BR 795-100-100; (ii) circuit identifier codes
                 as described in BR 795-400-100; and (iii) Trunk Group Serial
                 Number (TGSN) as described in BR 751-100-195.

          4.6.2  Description of major network projects that affect the other
                 Party will be provided with the semi-annual forecasts provided
                 pursuant to Section 4.6.1. Major network projects include but
                 are not limited to trunking or network rearrangements, shifts
                 in anticipated traffic patterns, or other activities by either
                 Party that are reflected by a significant increase or decrease
                 in trunking demand for the following forecasting period.

          4.6.3  GTE and ELI will work together to begin providing these
                 forecasts within thirty (30) days after the effective date of
                 this Agreement. New trunk groups will be implemented as
                 dictated by engineering requirements for either Party.

          4.6.4  The Parties will meet to review and reconcile their forecasts
                 if their respective forecasts differ significantly from one
                 another.

                                      V-8
<PAGE>

     4.7  Trunk Facility Underutilization.  At least once a year the Parties
          -------------------------------
          shall exchange trunk group measurement reports for trunk groups
          terminating to the other Party's network.  In addition and from time
          to time, each Party will determine the required trunks for each of the
          other Party's trunk groups from the previous 12 months servicing data.
          Required trunks will be based on an objective P.01 grade of service or
          the Joint Interconnection Grooming Plan referenced in Section 4.3.6
          above.  Likewise, from time to time trunk groups with excess capacity
          will be identified to the other Party as eligible for downsizing.  The
          Party with excess trunking capacity will assess the trunk capacity
          based on forecasted requirements for the next 12 months.  If after 12
          months the trunk group continues to have excess capacity, the Party
          agrees to take steps to disconnect all excess capacity.

5.   Indirect Network Interconnection.  The Parties agree to use their best
     --------------------------------
     efforts to establish direct interconnections for the exchange of traffic
     and to use indirect interconnection only if traffic volumes do not justify
     direct connection and both Parties subtend another LEC's tandem.  Until
     such time as compensation arrangements have been established in accordance
     with Sections 3.1 and 3.4 of this Article or the Parties mutually agree
     otherwise, ELI shall not deliver traffic destined to terminate at a GTE end
     office via another LEC's end office, and ELI shall not deliver traffic
     destined to terminate at an end office subtending a GTE tandem via another
     LEC's access tandem or switch, nor shall GTE deliver traffic destined to
     terminate at ELI's switch via another LEC's access tandem or switch.

6.   Number Resources.
     ----------------

     6.1  Number Assignment.  Nothing in this Agreement shall be construed to,
          -----------------
          in any manner, limit or otherwise adversely impact ELI's right to
          employ or to request and be assigned any NANP number resources
          including, but not limited to, Central Office (NXX) Codes pursuant to
          the Central Office Code Assignment Guidelines.  Any request for
          numbering resources by ELI shall be made directly to the NANP Number
          Plan Administrator.  Except with respect to those areas in which GTE
          is the NANP Number Plan Administrator, GTE shall not be responsible
          for the requesting or assignment of number resources to ELI.  The
          Parties agree that disputes arising from numbering assignment shall be
          arbitrated by the NANP Number Plan Administrator.  ELI shall not
          request number resources to be assigned to any GTE switching entity.

          6.1.1  Each Party shall be responsible for notifying its customers of
                 any changes in numbering or dialing arrangements to include
                 changes such as the introduction of new NPAs or new NXX codes.
                 Each Party is responsible for administering NXX codes assigned
                 to it.

     6.2  Rate Centers.  For purposes of compensation between the Parties and
          ------------
          the ability of the Parties to appropriately apply their respective
          toll rates to their end user customers, ELI shall adopt the Rate
          Center areas and Rate Center points that the

                                      V-9
<PAGE>

          Commission has approved for the incumbent LECs and shall assign whole
          NPA-NXX codes to each Rate Center. This adoption is for the sole
          purpose of compensation between the Parties and shall not limit ELI's
          ability to define local calling areas for its end user customers.

     6.3  Routing Points.  ELI will also designate a Routing Point for each
          --------------
          assigned NXX code.  ELI may designate one location within each Rate
          Center as a Routing Point for the NPA-NXX associated with that Rate
          Center; alternatively ELI may designate a single location within one
          Rate Center to serve as the Routing Point for all the NPA-NXXs
          associated with that Rate Center and with one or more other Rate
          Centers served by ELI within an existing GTE exchange area and LATA.

     6.4  Code and Numbers Administration.  The Parties will comply with code
          -------------------------------
          administration requirements as prescribed by the FCC, the Commission,
          and accepted industry guidelines.  Where GTE is the NANP Number Plan
          Administrator, GTE will administer number resources, and charge for
          such administration in accord with applicable rules and regulations.
          GTE will administer numbering resources in a nondiscriminatory and
          competitively neutral manner, and process requests for NXX codes in a
          timely manner and in accord with industry standards.  The Parties
          shall protect ELI proprietary information that may be submitted to GTE
          in connection with GTE's responsibilities as NANP Number Plan
          Administrator in accordance with Article III, Section 11 of this
          Agreement.

     6.5  Programming Switches.  It shall be the responsibility of each Party to
          --------------------
          program and update its own switches and network systems pursuant to
          the Local Exchange Routing Guide ("LERG") guidelines to recognize and
          route traffic to the other Party's assigned NXX codes at all times.
          Neither Party shall impose any fees or charges whatsoever on the other
          Party for such activities.

7.  Number Portability.
    ------------------

    7.1   General.  The Parties shall develop and deploy number portability in
          -------
          accordance with the Act and all applicable FCC, State, and Commission
          requirements and industry standards.  Upon implementation of permanent
          local number portability ("LNP"), the Parties shall transition all
          interim local number portability ("INP") customers and their services
          to LNP methods within a mutually agreeable time frame and discontinue
          further use of interim methods of number portability.

     7.2  Interim Number Portability.  Each Party shall provide the other Party
          --------------------------
          with service provider number portability as an INP option for the
          purpose of allowing end user customers to change service-providing
          Parties within the same wire center without changing their telephone
          number.  The Parties shall provide service provider number portability
          to each other using remote call forwarding ("RCF").  Either

                                     V-10
<PAGE>

          Party may request another form of INP on an individual case basis and
          subject to terms and conditions negotiated between the Parties.

     7.3  Remote Call Forwarding.  Until permanent number portability is
          ----------------------
          implemented, the Parties agree to provide service provider number
          portability using RCF to each other on a Bill-and-Keep basis.  Neither
          Party shall bill the other for nonrecurring or recurring charges for
          ported numbers, and Provider shall retain all access charge revenues
          for interexchange calls terminated to ported numbers.  After permanent
          number portability is implemented, the Parties agree to renegotiate
          compensation for number portability, if necessary, in accordance with
          the FCC's permanent number portability requirements.  Subject to the
          technical capabilities of each switch type, the Party ordering RCF may

          ported number as necessary to provide for existing service levels and
          projected growth.

8.  Meet-Point Billing for Switched Access Service.
    ----------------------------------------------

    8.1   Meet-Point Arrangements.
          -----------------------

          8.1.1  The Parties may mutually establish Meet-Point Billing ("MPB")
                 arrangements in order to provide Switched Access Services to
                 Access Service customers via a GTE tandem in accordance with
                 the MPB guidelines adopted by and contained in the Ordering and
                 Billing Forum's MECAB and MECOD documents, except as modified
                 in this Article and Section 7 of Article III.

          8.1.2  Except in instances of capacity limitations, GTE shall permit
                 and enable ELI to sub-tend the GTE access tandem(s) nearest to
                 the ELI Rating Point(s) associated with the NPA-NXX(s) to/from
                 which the Switched Access Services are homed. In instances of
                 capacity limitation at a given access tandem, ELI shall be
                 allowed to subtend the next-nearest GTE access tandem in which
                 sufficient capacity is available.

          8.1.3  Interconnection for the MPB arrangement shall occur at the
                 "IP".

          8.1.4  Common Channel Signaling shall be utilized in conjunction with
                 MPB arrangements to the extent such signaling is resident in
                 the GTE access tandem switch.

          8.1.5  ELI and GTE will use diligent efforts, individually and
                 collectively, to maintain provisions in their respective
                 federal and state access tariffs, and/or provisions within the
                 National Exchange Carrier Association ("NECA") Tariff No. 4, or
                 any successor tariff, sufficient to reflect this MPB
                 arrangement, including MPB percentages.

<PAGE>

          8.1.6  As detailed in the MECAB document or other applicable
                 requirements, ELI and GTE will, in a timely fashion, exchange
                 all information necessary to accurately, reliably and promptly
                 bill Access Service customers for Switched Access Services
                 traffic jointly handled by ELI and GTE via the meet-point
                 arrangement. Information shall be exchanged in Electronic
                 Message Record ("EMR") format, on magnetic tape or via a
                 mutually acceptable electronic file transfer protocol.

          8.1.7  ELI and GTE shall work cooperatively to coordinate rendering of
                 Meet-Point bills to customers, and shall reciprocally provide
                 each other usage data and related information at the
                 appropriate charge.

     8.2  Access Compensation.
          -------------------

          8.2.1  Initially, billing to Access Service customers for the Switched
                 Access Services jointly provided by ELI and GTE via the MPB
                 arrangement shall be according to the multiple-bill method as
                 described in the MECAB guidelines. This means each Party will
                 bill the portion of service they provided at their appropriate
                 tariff, or price list.

          8.2.2  Subsequently, ELI and GTE may mutually agree to implement one
                 of the following options for billing to third parties for the
                 Switched Access Services jointly provided by ELI and GTE via
                 the MPB arrangement: single-bill/single tariff method, single-
                 bill/multiple tariff method, or to continue the multiple-bill
                 method. Should either Party prefer to change among these
                 billing methods, that Party shall notify the other Party of
                 such a request in writing, ninety (90) Business Days in advance
                 of the date on which such change is desired to be implemented.
                 Such changes then may be made in accordance with MECAB
                 guidelines and if the Parties mutually agree, the change will
                 be made.

                 unbrand OS and DA, GTE will provide it where GTE performs its
                 own OS and DA service subject to capability and capacity
                 limitations where customized routing is Currently Available. If
                 GTE uses a Third Party contractor to provide OS or DA, GTE will
                 not provide branding nor will GTE negotiate it with a Third
                 Party on behalf of ELI. ELI must negotiate with the Third
                 Party. In these instances ELI will need to purchase customized
                 routing and dedicated trunking to differentiate its OS/DA
                 traffic from GTE's traffic.

                                  ARTICLE VII
                           UNBUNDLED NETWORK ELEMENTS

On January 25, 1999, the Supreme Court of the United States issued its decision
on the appeals of the Eighth Circuit's decision in Iowa Utilities Board.
Specifically, the Supreme Court vacated Rule 51.319 of the FCC's First Report
and Order, FCC 96-325, 61 Fed. Reg. 45476 (1996) and modified several of the
FCC's and the Eighth Circuit's rulings regarding unbundled network elements and
pricing requirements under the Act.  AT&T Corp. v. Iowa Utilities Board, No. 97-
826, 1999 U.S. LEXIS 903 (1999).  Under Section 251 (d)(2), the FCC was required
to determine what UNEs should be made available, and it listed them in the now-
vacated FCC Rule 51.319.  Thus, there is currently no determination of what, if
any, UNEs should be made available under the law, and until this determination
is made there is no legal obligation to provide any particular UNEs. Without
waiving any rights and only on an interim basis, GTE agrees to provide the UNEs
listed herein ("Old 319 UNEs") in accordance with the associated provisions in
the agreement and only upon the following interdependent terms and conditions:

Until the FCC issues new and final rules with regard to vacated Rule 51. 319
that comply with the Act ("New Rules"), GTE will provide the Old 319 UNEs listed
below even though it is not legally obligated to do so; provided, however, that
ELI agrees not to seek UNE "platforms," or "already bundled" combinations of
UNEs.

ELI agrees that after the final FCC Rules are issued, the Parties will determine
what UNEs should be included in the Agreement as required by the Act, and they
will incorporate them into the Agreement.  If the Parties cannot agree on what
UNEs are then required under the Act, either Party at any time may seek to
incorporate the appropriate UNEs under the Act into the agreement in accord
with Sections 32 and 40 of Article III, the change of law provision(s) of the
Agreement, notwithstanding anything to the contrary or the expiration of any
time periods outlined in such provision(s) or any other provision of the
Agreement.

By providing Old 319 UNEs, GTE does not waive any of its rights, including its
rights to seek recovery of its actual costs and a sufficient, explicit universal
service fund.  Nor does GTE waive its position that, under the Court's decision,
it is not required to provide Old 319 UNEs unconditionally.  Moreover, GTE does
not agree that the Old 319 UNE rates set forth below are just and reasonable and
in accordance with the requirements of sections 251 and 252 of Title 47 of the
United States Code.

The above "status quo" arrangement applies only to UNEs, UNE pricing, unbundling
and UNE platform issues.  The Parties have not determined if other provisions of
the Agreement are inconsistent with the law.  To the extent there are other
provisions in the Agreement that are inconsistent with, or impacted by the law,
including the Supreme Court's decision in Iowa Utilities Board, it is the intent
of the Parties that the Agreement should conform thereto and that the "change of
law" provisions therein may be invoked to accomplish that end.

1.   General.  The purpose of this Article VII is to define the unbundled
     -------
     network elements that may be leased by ELI from GTE.  Unless otherwise
     specified in this Agreement and to the extent not inconsistent with this
     Agreement, the Act, or state or federal law, provisioning of unbundled
     network arrangements will be governed with the GTE Customer Guide for CLEC
     Establishment of Services -- Resale and Unbundling (the

                                     VII-1
<PAGE>

     "Guide"). Additional procedures for preordering, ordering, provisioning and
     billing of unbundled network elements are outlined in Appendix H.
                                                           ----------

2.   Unbundled Network Elements.
     --------------------------

     2.1  Categories.  There are several separate categories of Network
          ----------
          Components that shall be provided as unbundled network elements by
          GTE:

          (a)  Network Interface Device or NID

          (b)  Loop Elements

          (c)  Port and Local Switching Elements

          (d)  Transport Elements

          (e)  Signaling Elements

     2.2  Prices.  The recurring and nonrecurring rates GTE shall charge ELI for
          ------
          individual unbundled network elements are set forth in Appendix F
                                                                 ----------
          attached to, and made a part of, this Agreement, or in the appropriate
          GTE tariff as referenced in this Article.

          2.2.1  Compensation for Exchange of Traffic Using Unbundled Network
                 ------------------------------------------------------------
                 Elements.  Compensation arrangements between GTE and ELI
                 --------
                 exchanging traffic when ELI uses GTE provided unbundled network
                 elements, i.e., port, local switching, and shared transport,
                 shall be as provided in Appendix L. The Parties have not
                 negotiated terms and conditions for Appendix L. At such time as
                 ELI desires to obtain unbundled ports, local switching, and
                 transport from GTE, the Parties agree to negotiate the terms
                 and conditions of Appendix L and to amend this Agreement
                 accordingly. ELI shall not obtain unbundled ports, local
                 switching and shared transport from GTE until such amendment
                 becomes effective.

     2.3  Interconnection to Unbundled Elements.  ELI may lease and interconnect
          -------------------------------------
          to any of these unbundled network elements, and subject to technical
          feasibility, may combine these unbundled elements with each other,
          with other GTE services and facilities, and/or with any facilities or
          services that ELI may itself provide subject to the provisions of this
          Article.

          2.3.1  Connection of ELI facilities to unbundled elements shall be
                 achieved via physical collocation arrangements ELI shall
                 maintain at the wire center at which the unbundled services are
                 resident. When physical collocation cannot be accommodated at
                 the wire center where the unbundled elements are resident,
                 alternative arrangements shall be negotiated between GTE

                                     VII-2
<PAGE>

                and ELI. Such arrangements may include virtual collocation. All
                reasonable incremental costs associated with the alternative
                arrangements shall be borne by ELI.

          2.3.2 GTE shall connect unbundled network elements to ELI's facilities
                at a collocation arrangement via an EIS cross connect element
                ("EISCC") as provided in GTE's federal collocation tariff. As
                part of the EISCC, GTE will provide a designated terminal block,
                or equivalent termination point, and terminate ELI's collocation
                cable facilities on the designated terminal block. The EISCC
                also provides for the cross connection to connect the unbundled
                network element to ELI's cable facilities on the designated
                terminal block. GTE has no obligation to combine any unbundled
                network elements for ELI; Provided, however, that to the extent
                that GTE may be specifically required to combine unbundled
                network elements and/or provide unbundled network elements in
                existing combinations pursuant to a final and effective decision
                that is binding on GTE, GTE will negotiate with ELI regarding
                the provisioning of such elements in accordance with that
                decision. Once GTE's unbundled network elements have been
                connected to ELI's facilities, as described in this Agreement,
                ELI is not precluded from combining the unbundled elements using
                its own facilities, except that ELI may not combine unbundled
                GTE network elements to provide solely interexchange service or
                solely access service to an interexchange carrier.

     2.4  Service Quality.  To the degree reasonably possible, all service
          ---------------
          attributes, grades-of-service and installation, maintenance and repair
          intervals which apply to the bundled service will apply to unbundled
          network elements.  GTE shall provide unbundled network elements to ELI
          that are equal in quality and performance standards to the same
          unbundled network elements GTE provides to its affiliates and other
          carriers.  Except as required by the express terms of this Agreement
          and by federal or State law, GTE shall not be responsible for impacts
          on service attributes, grades of service, etc., resulting from ELI's
          specific use of or modification to any unbundled network element.

     2.5  Nondiscrimination Provision and Support.  GTE shall provide unbundled
          ---------------------------------------
          network elements in as timely a manner as the volume of requests
          reasonably allows and consistent with the service provisioning terms
          and conditions in this Agreement and state or federal requirements.
          GTE shall provision unbundled network elements in a non-discriminatory
          manner and shall provide power to such elements on the same basis as
          GTE provides to itself, its affiliates and other carriers to whom GTE
          provides unbundled network elements.

3.  Network Interface Device.
    ------------------------

                                     VII-3
<PAGE>

     3.1  Direct Connection.  ELI must terminate any unbundled loop leased from
          -----------------
          GTE to a GTE Network Interface Device ("NID"), and GTE shall provide
          the NID in its existing combination with the unbundled loop.  ELI
          shall be permitted to connect its own loop directly to GTE's NID as
          long as such direct connection does not adversely affect GTE's
          network.  In order to minimize any such adverse effects, ELI shall
          follow the procedures in Sections 3.1.1 and 3.1.2 below.

          3.1.1  When connecting its own loop facility directly to GTE's NID for
                 a residence or business customer, ELI must make a clean cut on
                 the GTE drop wire at the NID so that no bare wire is exposed.
                 ELI shall not remove or disconnect GTE's drop wire from the NID
                 or take any other action that might cause GTE's drop wire to be
                 left lying on the ground.

          3.1.2  At multi-tenant customer locations, ELI must remove the jumper
                 wire from the distribution block (i.e. the NID) to the GTE
                 cable termination block. If ELI cannot gain access to the cable
                 termination block, ELI must make a clean cut at the closest
                 point to the cable termination block. At ELI's request and
                 discretion, GTE will determine the cable pair to be removed at
                 the NID in multi-tenant locations. ELI will compensate GTE for
                 locating the cable pair to be removed at the nonrecurring Loop
                 Facility Charge specified in Appendix F.

          3.1.3  GTE agrees to offer NIDs for lease to ELI but not for sale. ELI
                 may remove GTE identification from any NID which it connects to
                 a ELI loop, but ELI may not place its own identification on
                 such NID.

     3.2  NID to NID Connection.  ELI may install its own NID and effect a NID
          ---------------------
          to NID connection between its NID and the GTE NID to gain access to
          the end user's inside wiring.

          3.2.1  If ELI provides its own loop facilities, it may elect to move
                 all inside wire terminated on a GTE NID to an ELI NID. In this
                 instance, a NID to NID connection will not be required. ELI, or
                 the end user premise owner, can elect to leave the GTE
                 disconnected NID in place, or to remove the GTE NID from the
                 premise and dispose of it entirely.

     3.3  Removal of Cable Pairs.  Removal of existing cable pairs required for
          ----------------------
          ELI to terminate service is the responsibility of ELI.

     3.4  Maintenance.  When ELI provides its own loop and connects directly to
          -----------
          GTE's NID, GTE does not have the capability to perform remote
          maintenance.  ELI can perform routine maintenance via its loop and
          inform GTE once the trouble has been isolated to the NID and GTE will
          repair (or replace) the NID, or, at ELI's option, ELI can make a NID
          to NID connection, using the GTE NID only to gain access to the inside
          wire at the customer location.

                                     VII-4
<PAGE>

     3.5  Collocation Requirement.  When ELI purchases a GTE NID as a stand-
          -----------------------
          alone unbundled element, the collocation arrangement described in
          Section 2.3.1 of this Article is not required.

4.  Loop Elements.
    -------------

     4.1  Service Description.  A "loop" is the transmission facility (or
          -------------------
          channel or group of channels on such facility) which extends from a
          Main Distribution Frame ("MDF") or functionally comparable piece of
          equipment in a GTE end office or wire center to a demarcation or
          connector block in/at a subscriber's premises.  Traditionally, loops
          were provisioned as 2-wire or 4-wire copper pairs running from the end
          office MDF to the customer premises.  However, a loop may be provided
          via other media, including radio frequencies, as a channel on a high
          capacity feeder/distribution facility which may, in turn, be
          distributed from a node location to the subscriber premises via a
          copper or coaxial drop facility, etc.

     4.2  Categories of Loops.  GTE shall provide the following general
          -------------------
          categories of loops according to their technical configuration and
          capabilities:

          4.2.1  "2-wire analog voice grade" loops will support analog
                 transmission of 300-3000 Hz, repeat loop start or ground start
                 seizure and disconnect in one direction (toward the end office
                 switch), and repeat ringing in the other direction (toward the
                 end user). This loop is commonly used for local dial tone
                 service. Rates are as reflected in Appendix F, including non-
                 recurring charges.

          4.2.2  "4-wire analog voice grade" loops conform to the
                 characteristics of a 2-wire voice grade loop and, in addition,
                 can support the simultaneous independent transmission of
                 information in both directions. Rates are as reflected in
                 Appendix F, including non-recurring charges.

          4.2.3  "2-wire digital" loops will support industry standard
                 specifications for digital transmission. Special provisioning
                 (removal of bridge taps and/or load coils) may be required to
                 conform to these industry standards. Rates are as reflected in
                 Appendix F, including non-recurring charges.

          4.2.4  "4-wire digital" loops will support industry standard
                 specifications for digital transmission. Special provisioning
                 (removal of bridge taps and/or load coils) may be required to
                 conform to these industry standards. Rates are as reflected in
                 Appendix F, including non-recurring charges.

          4.2.5  "DS-1" loops will support a digital transmission rate of 1.544
                 Mbps. The DS-1 loop will have no bridge taps or load coils and
                 will employ special line treatment. DS-1 loops will include
                 span line repeaters where required,

                                     VII-5
<PAGE>

                 office terminating repeaters, and DSX cross connects. Prices
                 and specifications for DS-1 grade loops are the prices set
                 forth in the appropriate GTE special access tariff.

          4.2.6  "DS-3" loops will support the transmission of isochronous
                 bipolar serial data at a rate of 44.736 Mbps. This DS-3 type of
                 loop provides the equivalent of 28 DS-1 channels and shall
                 include the electronics at either end. Prices and
                 specifications for DS-3 grade loops are the prices set forth in
                 the appropriate GTE special access tariff.

     4.3  Conditioned Loops.
          -----------------

          4.3.1  ELI may also require that analog loops ordered above be
                 conditioned in order for them to provide the end-user service.
                 Examples of this type of conditioning are: Type C, Type DA,
                 Improved C, etc. The price for such conditioned loops shall be
                 the applicable charge as provided in the appropriate GTE
                 intrastate special access tariff.

          4.3.2  Digital loops ordered above shall be provisioned to meet
                 industry standard service levels for generally available
                 digital services, such as ISDN or xDSL, without the requirement
                 for ordering additional conditioning. ELI must indicate on the
                 order, via industry standard ordering codes, the service
                 capability requested. Additional charges may apply for services
                 such as deloading the cable pair or providing midspan
                 repeaters.

     4.4  Loop Testing.
          ------------

          4.4.1  GTE will not perform routine testing of the unbundled loop for
                 maintenance purposes. ELI will be required to provision a loop
                 testing device either in its central office (switch location),
                 Network Control Center or in its collocation arrangement to
                 test the unbundled loop. GTE will perform repair and
                 maintenance once trouble is identified by ELI.

          4.4.2  All loop facilities furnished by GTE on the premises of ELI's
                 end users and up to the network interface or functional
                 equivalent are the property of GTE. GTE must have access to all
                 such facilities for network management purposes. GTE employees
                 and agents may enter said premises at any reasonable hour to
                 test and inspect such facilities in connection with such
                 purposes or, upon termination or cancellation of the loop
                 facility, to remove such facility.

          4.4.3  If ELI leases digital loops to transmit specified digital
                 signals, GTE will test the loop and provide recorded test
                 results to ELI as a part of provisioning that loop. If loop
                 tests are conducted in maintenance and repair cases, GTE will
                 provide any recorded readings to ELI at the time

                                     VII-6
<PAGE>

                 the trouble ticket is closed in the same manner as GTE provides
                 to itself and its end users, affiliates, and carriers to whom
                 GTE provides loops.

     4.5  Pair Gain Technologies.  GTE cannot provide an unbundled loop that
          ----------------------
          currently is being provisioned using integrated digital loop carrier
          ("IDLC") technology or analog carrier technology.  Where GTE utilizes
          other types of pair gain technology to provision the loop element, GTE
          may be able to provide an unbundled loop, depending on the technology
          involved, but the capabilities of the loop may be limited.  If ELI
          orders an unbundled loop to a location that is normally served by pair
          gain technology and GTE cannot meet the requirements of the ordered
          loop using the pair gain technology, GTE will use alternate
          facilities, if available, to provision the loop.  If alternate
          facilities are not available, GTE will advise ELI that facilities are
          not available to provision the loop.  GTE will not construct
          additional facilities at GTE's expense to provide the loop for ELI,
          but ELI may use the bona fide request process in Article VIII of this
          Agreement to request that GTE construct additional facilities at ELI's
          expense.

          4.5.1  GTE will work with ELI to develop a joint planning process to
                 allow ELI to assess the impact of GTE's use of pair gain
                 technology in marketing ELI services that are dependent on
                 unbundled loops provided by GTE. Such a process will provide
                 general information as to the type and relative use of pair
                 gain technology in a market, as well as the capability to
                 determine on a customer specific/route specific basis if pair
                 gain technology is used to provision the loop.

          4.5.2  GTE will permit ELI to collocate digital loop carriers and
                 associated equipment in conjunction with collocation
                 arrangements ELI maintains at a GTE wire center for the purpose
                 of interconnecting to unbundled loop elements.

     4.6  Unbundled Loop Facility Certification.
          -------------------------------------

          4.6.1  Before deploying any service enhancing copper cable technology
                 (e.g., HDSL, ISDN, etc.) over unbundled analog voice grade
                 loops leased from GTE, ELI shall notify GTE of such intentions
                 to enable GTE to assess the loop transport facilities to
                 determine whether there are any existing copper cable loop
                 transport technologies (e.g., analog carrier, etc.) deployed
                 within the same cable sheath that would be interfered with if
                 ELI deployed the proposed service enhancing copper cable
                 technology. If there are existing copper cable loop transport
                 technologies already deployed within the same cable sheath, or
                 if GTE already has existing near term (within 18

                 months of the date of facility certification) plans to deploy
                 copper cable loop transport technologies that would be
                 interfered with as described above, GTE will so inform ELI and
                 ELI shall not be permitted to deploy such service enhancing
                 copper cable technologies. GTE, however, will work with ELI to
                 provide alternate facilities that will enable ELI to deploy
                 ELI's proposed service enhancing copper cable technology. GTE
                 will charge ELI the applicable engineering time and labor costs
                 to perform the certification.

          4.6.2  If ELI fails to notify GTE of its plans to deploy service
                 enhancing copper cable technology over unbundled analog voice
                 grade loops and obtain prior certification from GTE of the
                 facilities, if ELI's deployment of such technology is
                 determined to have caused interference with existing or planned
                 copper cable loop transport technologies deployed by GTE in the
                 same cable sheath, ELI will immediately remove such service
                 enhancing copper cable technology and shall reimburse GTE for
                 all reasonably incurred expense related to this interference.

          4.6.3  If ELI orders digital loops as specified above and provides the
                 industry standard codes on the order indicating the type of
                 service to be deployed on the loop, no notification is
                 required. GTE will determine if compatibility issues exist and,
                 if facilities are available, will provide a loop capable of
                 meeting the requested service capabilities.

     4.7  Compatibility.  Provided ELI has notified GTE, pursuant to section 4.6
          -------------
          above, of the service enhancing copper cable technology deployed on an
          unbundled loop, GTE will not deploy service enhancing copper cable
          technology within the same cable sheath that will be incompatible with
          ELI's technology.

     4.8  Subloops.
          --------

          4.8.1  GTE will provide as separate items the loop distribution, loop
                 concentrator and loop feeder on a case-by-case basis pursuant
                 to a Bona Fide Request ("BFR").

          4.8.2  GTE will design and construct loop access facilities (including
                 loop feeders and loop concentration/multiplexing systems) in
                 accordance with standard industry practices as reflected in
                 applicable tariffs and/or as agreed to by GTE and ELI.

          4.8.3  Transport for loop concentrators/multiplexers services not
                 supported by embedded technologies will be provided pursuant to
                 applicable tariffs or as individually agreed upon by GTE and
                 ELI. The Parties understand that embedded loop
                 concentrators/multiplexers are not necessarily capable of
                 providing advanced and/or digital services.

                                     VII-8
<PAGE>

          4.8.4  GTE will provide loop transmission characteristics as specified
                 in Section 4.4.3 of this Article.

     4.9  Loop Identification.  At a multi-tenant location, GTE will identify
          -------------------
          the cable pair, at the cable termination block or at the distribution
          block (NID), used to provide the unbundled loop.  If the cable pair is
          not properly marked, GTE will take the necessary steps to identify the
          cable pair at no additional charge to ELI.

5.   Port and Local Switching Elements.
     ---------------------------------

     5.1  Port.  A "port" provides for the interconnection of individual loops
          ----
          or trunks to the switching components of GTE's network.  In general,
          it is a line card or trunk card and associated peripheral equipment on
          GTE end office switch that serves as the hardware termination for the
          end user's Exchange Service on that switch and generates dial tone and
          provides the end user access to the public switched telecommunications
          network.  The port does not include such features and functions which
          are provided as part of Local Switching.  Each line-side port is
          typically associated with one (or more) telephone number(s), which
          serve as the end user's network address.

     5.2  Ports Available as Unbundled Network Elements.  There are four types
          ---------------------------------------------
          of ports available as unbundled network elements;

          5.2.1  "2-wire analog line" port is a line side switch connection
                 employed to provide basic residential and business type
                 Exchange Service.

          5.2.2  "2-wire ISDN digital line" port is a Basic Rate Interface
                 ("BRI") line side switch connection employed to provide ISDN
                 Exchange Services.

          5.2.3  "DS-1 digital trunk" port is a trunk side switch connection
                 employed to provide the equivalent of 24 analog incoming trunk
                 type Exchange Services, such as direct inward dialing ("DID").

          5.2.4  "4-wire ISDN digital DS-1 trunk" port is a Primary Rate
                 Interface ("PRI") trunk side switch connection employed to
                 provide the ISDN Exchange Services.

     5.3  Port Prices.  Prices for ports are listed in Appendix F.
          -----------                                  ----------

     5.4  Local Switching.  "Local switching" provides the basic switching
          ---------------
          functions to originate, route and terminate traffic and any signaling
          deployed in the switch.  Vertical features are optional services
          provided through software programming in the switch which can be added
          on a per-feature basis with applicable rate.  GTE will offer only
          those features and functions currently available to the particular
          platform used (e.g., DMS, 5ESS, GTD5).  Any feature or function which
          is not

                                     VII-9
<PAGE>

          available, but the switch is capable of providing, may be requested
          via the BFR process. ELI will be responsible for bearing any costs
          incurred by GTE in making such feature/function available, including
          Right-to-Use ("RTU") fees. The rates for local switching and vertical
          features are listed in Appendix F.
                                 ----------

          5.4.1  ELI must purchase local switching with the line-side port or
                 trunk-side port, if applicable, and GTE shall provide the local
                 switching in its existing combination with the applicable port.

     5.5  Compliance with Section 2.3.  ELI shall only order unbundled elements
          ---------------------------
          in accordance with Section 2.3 herein and it will be the
          responsibility of ELI to make arrangements for the delivery of
          interexchange traffic and routing of traffic over interoffice
          transmission facilities, if applicable.

     5.6  Shared Transport.  "Shared transport" is the physical interoffice
          ----------------
          facility medium that is used to transport a call between switching
          offices.  A central office switch translates the end user dialed
          digits and routes the call over a Common Transport Trunk Group that
          rides interoffice transmission facilities.  These trunk groups and the
          associated interoffice transmission facilities are accessible by any
          end user (GTE end user or CLEC end user when the CLEC has purchased
          unbundled local switching) and are referred to as "shared transport
          facilities."

          5.6.1  Many calls riding shared transport facilities will also be
                 switched by GTE's access tandem. This tandem switching function
                 is included as a rate component of shared transport, as set
                 forth in Appendix D. GTE will provide shared transport from a
                 call originating from an unbundled switch port to the point
                 where the call leaves GTE's network (the IP).

          5.6.2  When ELI purchases unbundled local switching, ELI is obligated
                 to purchase unbundled shared transport. All of the billing
                 elements associated with shared transport are billed upon call
                 origination, unless the call involves an IXC.

          5.6.3  The rating of shared transport is based on the duration of a
                 voice grade (or DS-0) call on GTE's network. Shared transport
                 is comprised of three billing components: (1) Shared Transport
                 - Facility Miles (usage and distance sensitive); (2) Shared
                 Transport - Termination (per end, usage sensitive); and (3)
                 Tandem Switching (usage sensitive). Until an industry standard
                 solution is implemented for generating AMA recordings that
                 indentify tandem routed calls, the parties will use a shared
                 transport composite rate using the tandem switching rate, two
                 (2) terminations, and an assumed facility miles length of ten
                 (10) miles. This interim methodology will be used in lieu of
                 actual detailed AMA recordings and bill generation.

                                    VII-10
<PAGE>

          5.6.4  GTE is responsible for the sizing of the shared transport
                 network. All analysis, engineering, and trunk augmentations to
                 Common Transport Trunk Groups will be the sole responsibility
                 of GTE. To ensure that the network is appropriately sized, GTE
                 may request traffic forecasts from ELI if ELI requests
                 unbundled local switching. These forecasts must be provided to
                 GTE on a quarterly basis, with a twelve (12) month outlook.

          5.6.5  GTE provides shared transport between GTE switching offices
                 (e.g., between GTE end offices, a GTE end office and a GTE
                 tandem switch, between a GTE end office and the IP of a
                 connecting telecommunications company, or between a tandem
                 switch and the IP of a connecting telecommunications company).
                 However, the transport between a GTE switching office and the
                 ELI switching office must be purchased as dedicated transport
                 and is not provided as shared transport.

6.   Dedicated Transport.
     -------------------

     6.1  Dedicated transport is purchased for the purpose of transporting
          Telecommunications Services between designated serving wire centers
          ("SWCs") within the same LATA.  Dedicated transport may extend between
          two GTE SWCs ("Interoffice Dedicated Transport" or "IDT") or may
          extend from the GTE SWC to the ELI premise ("CLEC Dedicated Transport"
          or "CDT").  CDT remains within the exchange boundaries of the SWC,
          while IDT traverses exchange boundaries.  IDT and CDT are further
          defined in Sections 6.2 and 6.3 below.

     6.2  CDT is the dedicated transport facility connecting the GTE SWC to
          ELI's Customer Designated Location ("CDL").  The CDL will be
          designated where the CLEC's physical network begins (the CDL cannot be
          designated at an end user customer location).

     6.3  CDT includes the equipment required to terminate the interoffice
          facility within ELI's CDLs and within the GTE SWC.  This element also
          includes the transport facility between the two locations but extends
          no farther into GTE's network than the CDL's SWC.  CDT has no
          switching components and is available in bandwidth increments of DS0,
          DS1, or DS3 at rates outlined in Appendix F.

     6.4  CDT consists of monthly recurring (non-usage sensitive) billable
          elements that are dependent on bandwidth, but may vary depending on
          the termination arrangement at the CDL (Office Terminating Repeater
          vs. SONET terminal, first system vs. additional system, etc.).

     6.5  IDT is the dedicated transport facility connecting two GTE SWCs and
          excludes the facilities between the SWC and the CDL.  IDT has no
          switching components and is available in bandwidth increments of DS0,
          DS1, and DS3 at rates outlined in Appendix F.

                                    VII-11

<PAGE>

     6.6  The price of IDT varies with the bandwidth and consists of monthly
          recurring (non-usage sensitive) billable elements.  The components are
          Transport Facility Miles (monthly recurring) and Transport Termination
          (per end, monthly recurring).

7.   SS7 Transport and Signaling.  SS7 signaling and transport services in
     ---------------------------
     support of ELI's local exchange services shall be provided in accordance
     with the terms and conditions of Appendix I attached to, and made a part
     of, this Agreement.

     7.1  GTE will provide interconnection with its SS7 at the STPs but not at
          other points.

8.   LIDB Services.  Access to GTE's LIDB shall be provided in accordance with
     -------------
     the rates, terms and conditions of GTE's switched access tariff, GTOC
     Tariff FCC No. 1, Section 8.

9.   Database 800-Type Services.  Access to GTE's 800-Type database (i.e., 888,
     --------------------------
     877) shall be provided in accordance with the rates, terms and conditions
     of GTE's switched access tariff, GTOC Tariff FCC No. 1, Section 8.

10.  Operator Services ("OS") and Directory Assistance ("DA").  GTE will provide
     --------------------------------------------------------
     OS and DA to ELI in accordance with the terms set forth as follows:

     10.1  When OS and/or DA is to be provided for calls that originate from
           ELI's switch, GTE will provide branded or unbranded OS and/or DA
           pursuant to separate contracts to be negotiated in good faith between
           the Parties after execution and approval of this Agreement by the
           Commission.

     10.2  When OS and/or DA is to be provided for calls that originate from an
           unbundled port with local switching under this Article and neither
           branding nor unbranding is requested, ELI's calls will access GTE's
           OS and/or DA platform and will be processed in the same manner as GTE
           calls.

     10.3  When OS and/or DA is to be provided for calls that originate from an
           unbundled port and local switching under this Article and either
           branding or unbranding is requested, GTE will provide such unbranding
           or rebranding on a switch-by-switch basis, subject to capability and
           capacity limitations. When technically capable of doing so, GTE shall
           implement an order for unbranding or rebranding within 90 Business
           Days of receipt of that order.

     10.4  To the extent authorized by the FCC and the Commission, ELI will be
           billed charges for OS and DA and a charge for unbranding or
           rebranding and Customized Routing as set forth in Section 11.2. In
           addition, charges specified in Section 11.4 will apply.

                                    VII-12
<PAGE>

     10.5  For those offices that ELI has requested GTE to rebrand and/or
           unbrand OS and DA, GTE will provide it where GTE provides its own OS
           and DA service subject to capability and capacity limitations where
           Customized Routing is currently available. If GTE uses a Third Party
           contractor to provide OS or DA, GTE will not provide branding nor
           will GTE negotiate it with a Third Party on behalf of ELI. ELI must
           negotiate with the Third Party. In these instances, ELI will need to
           purchase customized routing to differentiate its OS/DA traffic from
           GTE's traffic.

11.  Customized Routing.  Where technically feasible and upon receipt of written
     ------------------
     request from ELI, GTE agrees to provide customized routing for the
     following types of calls:

                          0-
                          0+Local
                          0+411
                          1+411
                          0+HNPA-555-1212 (intraLATA, only when intraLATA
                          presubscription is not available)
                          1+HNPA-555-1212 (intraLATA, only when intraLATA
                          presubscription is not available)

          11.1.1  GTE will provide ELI a list of switches that can provide
                  customized routing using line class codes or similar method
                  (regardless of current capacity limitations). ELI will return
                  a list of these switches ranked in priority order. GTE will
                  return to ELI a schedule for customized routing in the
                  switches with existing capabilities and capacity.

          11.1.2  Upon written request from ELI, GTE will provide ELI with
                  applicable charges, and terms and conditions, for providing OS
                  and DA, branding, and Customized Routing.

          11.1.3  Subject to the above provisions, GTE will choose the method of
                  implementing customized routing of OS and DA calls.

          11.1.4  The use of customized routing will require the purchase of a
                  trunk side port and dedicated facilities between the GTE end
                  office and the designated OS/DA platform. The rates for these
                  elements will be billed in accordance with Appendix F.
                                                             ----------


12.  Advanced Intelligent Network Access ("AIN").  GTE will provide ELI access
     -------------------------------------------
     to GTE AIN functionality from GTE's AIN SCP via GTE's local switch or ELI's
     local switch.

13.  Directory Assistance Listing.  When ELI orders an unbundled port, ELI has

            ADDITIONAL SERVICES AND COORDINATED SERVICE ARRANGEMENTS


1.   Bona Fide Request Process.
     -------------------------

     1.1  Intent.  The Bona Fide Request process is intended to be used when ELI
          ------
          requests customized Service Orders for certain services, features,
          capabilities or functionality defined and agreed upon by the Parties
          as services to be ordered as Bona Fide Requests.

     1.2  Process.
          -------

          1.2.1  A Bona Fide Request shall be submitted in writing by ELI and
                 shall specifically identify the need to include technical
                 requirements, space requirements and/or other such
                 specifications that clearly define the request such that GTE
                 has sufficient information to analyze and prepare a response.

          1.2.2  Although not expected to do so, ELI may cancel a Bona Fide
                 Request in writing at any time prior to ELI and GTE agreeing to
                 price and availability. GTE will then cease analysis of the
                 request.

          1.2.3  Within two (2) Business Days of its receipt, GTE shall
                 acknowledge in writing the receipt of the Bona Fide Request and
                 identify a single point of contact and any additional
                 information needed to process the request.

          1.2.4  Except under extraordinary circumstances, within ten (10)
                 Business Days of its receipt of a Bona Fide Request, GTE shall
                 provide a proposed price and availability date, or it will
                 provide an explanation as to why GTE elects not to meet ELI's
                 request. If extraordinary circumstances prevail, GTE will
                 inform ELI as soon as it realizes that it cannot meet the ten
                 (10) Business Day response due date. ELI and GTE will then
                 determine a mutually agreeable date for receipt of the request.

          1.2.5  Unless ELI agrees otherwise, all proposed prices shall be
                 consistent with the pricing principles of the Act, FCC and/or
                 the Commission. Payments for services purchased under a Bona
                 Fide Request will be made upon delivery, unless otherwise
                 agreed to by ELI, in accordance with the applicable provisions
                 of the Agreement.

          1.2.6  Upon affirmative response from GTE, ELI will submit in writing
                 its acceptance or rejection of GTE's proposal. If at any time
                 an agreement cannot be reached as to the terms and conditions
                 or price of the request

                                    VIII-1
<PAGE>

               GTE agrees to meet, the Dispute resolution procedures described
               in Article III hereunder may be used by a Party to reach a
               resolution.

2.   Transfer of Service Announcements.  For services other than GTE resold and
     ---------------------------------
     ported number services, when an end user customer transfers service from
     one Party to the other Party, and does not retain its original telephone
     number, the Party formerly providing service to the end user will provide,
     upon request and if such service is provided to its own customers, a
     referral announcement on the original telephone number.  This announcement
     will provide the new number of the customer and will remain in effect for
     the same time period this service is provided to GTE's own end users.  For
     GTE resold and ported number services, GTE shall provide an intercept
     referral on behalf of ELI.

3.   Misdirected Calls.  The Parties will employ the following procedures for
     -----------------
     handling any misdirected calls (e.g., Business office, repair bureau,
     etc.).

     3.1  To the extent the correct provider can be determined, each Party will
          refer misdirected calls to the proper provider of local exchange
          service.  When referring such calls, both Parties agree to do so in a
          courteous manner, at no charge.

     3.2  For misdirected repair calls, the Parties will provide their
          respective repair bureau contact number to each other on a reciprocal
          basis and provide the end user the correct contact number.

     3.3  In responding to misdirected calls, neither Party shall make
          disparaging remarks about each other, nor shall they use these calls
          as a basis for internal referrals or to solicit end users or to market
          services.

4.   911/E911 Arrangements.
     ---------------------

     4.1  Description of Service.  ELI will install a minimum of two (2)
          ----------------------
          dedicated trunks to GTE's 911/E911 selective routers (i.e., 911 tandem
          offices) that serve the areas in which ELI provides Exchange Services,
          for the provision of 911/E911 services and for access to all
          subtending PSAPs.  The dedicated trunks shall be, at a minimum, DS-0
          level trunks configured as a 2-wire analog interface or as part of a
          digital (1.544 Mbps) interface in which all circuits are dedicated to
          9-1-1 traffic.  Either configuration shall use CAMA type signaling
          with multifrequency ("MF") tones that will deliver ANI with the voice
          portion of the call.  GTE will provide ELI with the appropriate CLLI
          codes and specifications of the tandem office serving area or the
          location of the primary PSAP when there is no 911 routing in that 911
          district.  If an ELI central office serves end users in an area served
          by more than one (1) GTE 911/E911 selective router, ELI will install a
          minimum of two (2) dedicated trunks in accordance with this Section to
          each of such 911/E911 selective routers or primary PSAP.

                                    VIII-2

     4.2  Transport.  If ELI desires to obtain transport from GTE to the GTE 911
          ---------
          selective routers, ELI may purchase such transport from GTE at the
          rates set forth in Appendix G.

     4.3  Cooperation and Level of Performance.  The Parties agree to provide
          ------------------------------------
          access to 911 /E911 in a manner that is transparent to the end user.
          The Parties will work together to facilitate the prompt, reliable and
          efficient interconnection of ELI's systems to the 911/E911 platforms,
          with a level of performance that will provide the same grade of
          service as that which GTE provides to its own end users.  To this end,
          GTE will provide documentation to ELI showing the correlation of its
          rate centers to its E911 tandems at rates set forth in Appendix G.

     4.4  Basic 911 and E911 General Requirements:
          ---------------------------------------

          4.4.1  Basic 911 and E911 provides a caller access to the appropriate
                 emergency service bureau by dialing a 3-digit universal
                 telephone number (911).

          4.4.2  Where GTE has a 911 selective router installed in the network
                 serving the 911 district, GTE shall use subscriber data derived
                 from the Automatic Location Identification/Database Management
                 System (ALI/DMS) to selectively route the 911 call to the
                 Public Safety Answering Point (PSAP) responsible for the
                 caller's location.

          4.4.3  All requirements for E911 also apply to the use of SS7 as a
                 type of signaling used on the interconnection trunks from the
                 local switch to an end office or a selective router.

          4.4.4  Basic 911 and E911 functions provided to ELI shall be at least
                 at parity with the support and services that GTE provides to
                 its subscribers for such similar functionality.

          4.4.5  Basic 911 and E911 access from Local Switching shall be
                 provided to ELI in accordance with the following:

                 4.4.5.1  GTE and ELI shall conform to all state regulations
                          concerning emergency services.

               4.4.5.2    For E911, both ELI and GTE shall use their respective
                          service order processes to update access line
                          subscriber data for transmission to the database
                          management systems. Validation will be done via MSAG
                          comparison listed in Section 4.4.5.5.

               4.4.5.3    If legally required by the appropriate jurisdiction,
                          GTE shall provide or overflow 911 traffic to be routed
                          to GTE Operator

                                     VIII-3
<PAGE>

                     Services or, at ELI's discretion, directly to ELI Operator
                     Services.

          4.4.5.4    Basic 911 and E911 access from the ELI local switch shall
                     be provided from GTE to ELI in accordance with the
                     following:

                     4.4.5.4.1  If required by ELI and technically feasible, GTE
                                shall interconnect direct trunks from the ELI
                                network to the E911 PSAP, or to the E911
                                selective routers as designated by ELI. Such
                                trunks may alternatively be provided by ELI.

                     4.4.5.4.2  In government jurisdictions where GTE has
                                obligations under existing Agreements as the
                                primary provider of the 911 System to the county
                                (i.e., "lead telco"), ELI shall participate in
                                the provision of the 911 System as follows:

                                4.4.5.4.2.1  Each Party shall be responsible for
                                             those portions of the 911 System
                                             for which it has control, including
                                             any necessary maintenance to each
                                             Party's portion of the 911 System.

                                4.4.5.4.2.2  ELI and GTE recognize that the lead
                                             telco in a 911 district has the
                                             responsibility of maintaining the
                                             ALI database for that district.
                                             Each company will provide its
                                             access line subscriber records to
                                             the database organization of that
                                             lead telco. ELI and GTE will be
                                             responsible for correcting errors
                                             when notified by either the 911
                                             district or its customer, and then
                                             submitting the corrections to the
                                             lead telco. Lead telco database
                                             responsibilities are covered in
                                             Section 4.4.5.5 of this Article.

                                4.4.5.4.2.3  ELI shall have the right to verify
                                             the accuracy of information
                                             regarding ELI customers in the ALI
                                             database using methods and
                                             procedures mutually agreed to by
                                             the Parties. The fee for this
                                             service shall be determined based
                                             upon the agreed upon solution.

                                    VIII-4

                     4.4.5.4.3  If a Third Party is the primary service provider
                                to a 911 district, ELI shall negotiate
                                separately with such Third Party with regard to
                                the provision of 911 service to the agency. All
                                relations between such Third Party and ELI are
                                totally separate from this Agreement and GTE
                                makes no representations on behalf of the Third
                                Party.

                     4.4.5.4.4  If ELI or Affiliate is the primary service
                                provider to a 911 district, ELI and GTE shall
                                negotiate the specific provisions necessary for
                                providing 911 service to the agency and shall
                                include such provisions in an amendment to this
                                Agreement.

                     4.4.5.4.5  Interconnection and database access shall be at
                                rates as set forth in Appendix G.

                     4.4.5.4.6  GTE shall comply with established, competitively
                                neutral intervals for installation of
                                facilities, including any collocation
                                facilities, diversity requirements, etc.

                     4.4.5.4.7  In a resale situation, where it may be
                                appropriate for GTE to update the ALI database,
                                GTE shall update such database with ELI data in
                                an interval no less than is experienced by GTE
                                subscribers, or than for other carriers,
                                whichever is faster, at no additional cost.

            4.4.5.5  The following are Basic 911 and E911 Database Requirements:

                     4.4.5.5.1  The ALI database shall be managed by GTE, but is
                                the property of GTE and any participating LEC or
                                CLEC which provides their records to GTE.

                     4.4.5.5.2  Copies of the MSAG shall be provided within five
                                (5) business days after the date the request is
                                received and provided on diskette or paper copy
                                at the rates set forth in Appendix G.

                     4.4.5.5.3  ELI shall be solely responsible for providing
                                ELI database records to GTE for inclusion in
                                GTE's ALI database on a timely basis.

                     4.4.5.5.4  GTE and ELI shall arrange for the automated
                                input and periodic updating of the E911 database
                                information

                                    VIII-5
<PAGE>

                                related to ELI end users. GTE shall work
                                cooperatively with ELI to ensure the accuracy of
                                the data transfer by verifying it against the
                                Master Street Address Guide ("MSAG"). GTE shall
                                accept electronically transmitted files or
                                magnetic tape that conform to National Emergency
                                Number Association ("NENA") Version #2 format.

                     4.4.5.5.5  ELI shall assign an E911 database coordinator
                                charged with the responsibility of forwarding
                                ELI end user ALI record information to GTE or
                                via a third-party entity, charged with the
                                responsibility of ALI record transfer. ELI
                                assumes all responsibility for the accuracy of
                                the data that ELI provides to GTE.

                     4.4.5.5.6  GTE shall update the database within one (1)
                                business day of receiving the data from ELI. If
                                GTE detects an error in the ELI provided data,
                                the data shall be returned to ELI within one day
                                from when it was provided to GTE. ELI shall
                                respond to requests from GTE to make corrections
                                to database record errors by uploading corrected
                                records within one day. Manual entry shall be
                                allowed only in the event that the system is not
                                functioning properly.

                     4.4.5.5.7  GTE agrees to treat all data on ELI subscribers
                                provided under this Agreement as strictly
                                confidential and to use data on ELI subscribers
                                only for the purpose of providing E911 services.

                     4.4.5.5.8  GTE shall adopt use of a Carrier Code (NENA
                                standard five-character field) on all ALI
                                records received from ELI. The Carrier Code will
                                be used to identify the carrier of record in NP
                                configurations. The NENA Carrier Code for ELI is
                                "ELI"; the NENA Carrier Code for GTE is "GTE."

         4.4.5.6  GTE and ELI will comply with the following requirements for
                  network performance, maintenance and trouble notification.

                     4.4.5.6.1  Equipment and circuits used for 911 shall be
                                monitored at all times. Monitoring of circuits
                                shall be done to the individual trunk level.
                                Monitoring shall be conducted by GTE for trunks
                                between the selective router and all associated
                                PSAPs.

                     4.4.5.6.2  Repair service shall begin immediately upon
                                report of a malfunction. Repair service includes
                                testing and diagnostic service from a remote
                                location, dispatch of or in-person visit(s) of
                                personnel. Where an on-site technician is
                                determined to be required, a technician will be
                                dispatched without delay.

                     4.4.5.6.3  GTE shall notify ELI forty-eight (48) hours in
                                advance of any scheduled testing or maintenance
                                affecting ELI 911 service. GTE shall provide
                                notification as soon as possible of any
                                unscheduled outage affecting ELI 911 service.

                     4.4.5.6.4  All 911 trunks must be capable of transporting
                                Baudot Code necessary to support the use of
                                Telecommunications Devices for the Deaf
                                ("TTY/TDDs").

            4.4.5.7  Basic 911 and E911 Additional Requirements

                     4.4.5.7.1  All ELI lines that have been ported via INP
                                shall reach the correct PSAP when 911 is dialed.
                                Where GTE is the lead telco and provides the
                                ALI, the ALI record will contain both the ELI
                                number and GTE ported number. The PSAP attendant
                                shall see both numbers where the PSAP is using a
                                standard ALI display screen and the PSAP
                                extracts both numbers from the data that is
                                sent. GTE shall cooperate with ELI to ensure
                                that 911 service is fully available to all ELI
                                end users whose telephone numbers have been
                                ported from GTE, consistent with State
                                provisions.

                     4.4.5.7.2  ELI and GTE shall be responsible for reporting
                                all errors, defects and malfunctions to one
                                another. GTE and ELI shall provide each other
                                with a point of contact for reporting errors,
                                defects, and malfunctions in the service and
                                shall also provide escalation contacts.

                     4.4.5.7.3  ELI may enter into subcontracts with third
                                parties, including ELI Affiliates, for the
                                performance of any of ELI's duties and
                                obligations stated herein.

<PAGE>

                     4.4.5.7.4  Where GTE is the lead telco, GTE shall provide
                                ELI with notification of any pending selective
                                router moves within at least ninety (90) days in
                                advance.

                     4.4.5.7.5  Where GTE is the lead telco, GTE shall establish
                                a process for the management of NPA splits by
                                populating the ALI database with the appropriate
                                new NPA codes.

                     4.4.5.7.6  Where GTE is the lead telco, GTE shall provide
                                the ability for ELI to update 911 database with
                                end user information for lines that have been
                                ported via INP or LNP.

     4.4.6  Basic 911 and E911 Information Exchanges and interfaces. Where GTE
            is the lead telco:

            4.4.6.1  GTE shall provide ELI access to the ALI Gateway which
                     interfaces to the ALI/DMS database.  GTE shall provide
                     error reports from the ALI/DMS database to ELI within one
                     (1) day after ELI inputs information into the ALI/DMS
                     database.  Alternately, ELI may utilize GTE or a Third
                     Party entity to enter subscriber information into the
                     database on a demand basis, and validate subscriber
                     information on a demand basis.  The rates are set forth in
                     Appendix G.

            4.4.6.2  GTE and ELI shall arrange for the automated input and
                     periodic updating of the E911 database information related
                     to ELI end users. GTE shall work cooperatively with ELI to
                     ensure the accuracy of the data transfer by verifying it
                     against the Master Street Address Guide ("MSAG"). GTE shall
                     accept electronically transmitted files or magnetic tape
                     that conform to National Emergency Number Association
                     ("NENA") Version #2 format.

            4.4.6.3  Updates to MSAG. Upon receipt of an error recording an ELI
                     subscriber's address from GTE, and where GTE is the lead
                     telco, it shall be the responsibility of ELI to ensure that
                     the address of each of its end users is included in the
                     Master Street Address Guide ("MSAG") via information
                     provided on ELI's Local Service Request ("LSR") or via a
                     separate feed established by ELI pursuant to Section
                     4.4.5.7 of this Article.

            4.4.6.4  The ALI database shall be managed by GTE, but is the
                     property of GTE and all participating telephone companies.
                     The interface

                                    VIII-8
<PAGE>

                         between the E911 Switch or Tandem and the ALI/DMS
                         database for ELI subscriber shall meet industry
                         standards.

     4.5  Compensation.  In situations in which GTE is responsible for
          ------------
          maintenance of the 911 /E911 database and can be compensated for
          maintaining ELI's information by the municipality, GTE will seek such
          compensation from the municipality.  GTE will seek compensation from
          ELI only if and to the extent that GTE is unable to obtain such
          compensation from the municipality.  GTE shall charge ELI a portion of
          the cost of the shared 911 /E911 selective router as set forth in
          Appendix G.

5.   Information Services Traffic.
     ----------------------------

     5.1  Billing and Collection and Information Service Traffic Remuneration.
          -------------------------------------------------------------------

          5.1.1  In the event GTE performs switching of Information Service
                 Traffic (i.e., 900-976, Internet, weather lines, sports
                 providers, etc.) associated with resale or unbundled network
                 elements for ELI, GTE shall provide to ELI the same call detail
                 records that GTE records for its own end users so as to allow
                 ELI to bill its end users. GTE shall not be responsible or
                 liable to ELI or any Information Service Provider for Billing
                 and Collection and/or any receivables of Information Service
                 Providers.

          5.1.2  Notwithstanding and in addition to Article III, Section 24, GTE
                 shall be indemnified and held harmless by ELI from and against
                 any and all suits, actions, losses, damages, claims, or
                 liability of any character, type, or description, including all
                 expenses of litigation and court cost which may arise as a
                 result of the provisions contained in Section 5.1.1 supra. The
                 indemnity contained in this section shall survive the
                 termination of this Agreement, for whatever reason.

          5.1.3  GTE agrees to notify ELI in writing within ten (10) working
                 days, by registered or certified mail, of any claim made
                 against GTE on the obligations indemnified against pursuant to
                 this Section 5.

          5.1.4  It is understood and agreed that the indemnity provided for in
                 this Section 5 is to be interpreted and enforced so as to
                 provide indemnification of liability to GTE to the fullest
                 extent now or hereafter permitted by law.

     5.2  900-976 Call Blocking.  GTE shall not unilaterally block 900-976
          ---------------------
          traffic in which GTE performs switching associated with resale or
          unbundled network elements.  GTE will block 900-976 traffic when
          requested to do so, in writing, by ELI.  ELI shall be responsible for
          all cost associated with the 900-976 call blocking request.  GTE
          reserves the right to block any and all calls which may harm or damage
          its network.

                                    VIII-9
<PAGE>

     5.3  Miscellaneous.  GTE reserves the right to provide to any Information
          -------------
               Service Provider a list of any and all Telecommunications
               Providers doing business with GTE.

6.   Telephone Relay Service.  Local and intraLATA Telephone Relay Service
     -----------------------
     ("TRS") enables deaf, hearing-impaired, or speech-impaired TRS users to
     reach other telephone users.  With respect to resold services, ELI's end
     users will have access to the state authorized TRS provider to the extent
     required by the Commission, including any applicable compensation
     surcharges.

7.   Directory Assistance (DA) and Operator Services (OS).  Where ELI is
     ----------------------------------------------------
     providing local service with its own switch, upon ELI's request GTE will
     provide to ELI rebranded or unbranded directory assistance services and/or
     operator services pursuant to separate contracts to be negotiated in good
     faith between the Parties.  If ELI so requests directory assistance
     services and/or operator services, such contracts shall provide for the
     following:

     7.1  Directory Assistance Calls. GTE directory assistance centers shall
          --------------------------
          provide number and addresses to ELI end users in the same manner that
          number and addresses are provided to GTE end users.  If information is
          provided by an automated response unit ("ARU"), such information shall
          be repeated twice in the same manner in which it is provided to GTE
          end users.  Where available, GTE will provide call completion to ELI
          end users in the same manner that call completion is provided to GTE
          end users.  GTE will provide its existing services to ELI end users
          consistent with the service provided to GTE end users.

     7.2  Operator Services Calls.  GTE operator services provided to ELI end
          -----------------------
          users shall be provided in the same manner GTE operator services are
          provided to GTE end users.  In accordance with GTE practices and at
          GTE rates, GTE will offer to ELI end users collect, person-to-person,
          station-to-station calling, Third Party billing, emergency call
          assistance, calling card services, credit for calls, time and charges,
          notification of the length of call, and real time rating.  GTE
          operators shall also have the ability to quote ELI rates upon request
          but only if there is appropriate cost recovery to GTE and to the
          extent it can be provided within the technical limitations of GTE's
          switches.  GTE will provide its existing services to ELI end users
          consistent with the service GTE provides to its own end users.

8.   Directory Assistance Listings Information.  GTE will include listings in
     -----------------------------------------
     its directory assistance database for ELI end users in the same geographic
     area as GTE provides directory assistance for GTE end users as specified in
     Article VI, Section 3.4.

     8.1  GTE shall provide to ELI, at ELI's request, for purposes of ELI
          providing ELI-branded directory assistance services to its local
          customers, within sixty (60) Business Days after an order for such
          tape is received, all published DA listings for that specific state
          via magnetic tape.  Such listings will be Confidential

                                    VIII-10
<PAGE>

          Information under this Agreement and ELI will use the listings only
          for its directory assistance services to its end users. If ELI uses a
          Third Party directory assistance service to its end users, ELI will
          ensure that such Third Party likewise treats the listings as
          Confidential Information under this Agreement, and uses them only for
          such directory assistance. Changes to the DA Listing Information shall
          be updated on a daily basis through the same means used to transmit
          the initial list. DA Listing Information provided shall indicate
          whether the customer is a residence or business customer. The rate to
          be paid by ELI to GTE will be reasonable and mutually agreed.

     8.2  The Parties will not release DA Listing Information that includes the
          other Party's end user information to Third Parties without the other
          Party's written approval.  The other Party will inform the Releasing
          Party if it desires to have the Releasing Party provide the other
          Party's DA Listing Information to the Third Party, in which case, the
          Releasing Party shall provide the other Party's DA Listing Information
          at the same time as the Releasing Party provides the Releasing Party's
          DA Listing Information to the Third Party.  The rate to be paid by the
          Releasing Party to the other Party shall be no more than the direct
          costs of compiling such information.  The other Party shall be
          responsible for billing the Third Party.

     8.3  The Parties will work together to identify and develop procedures for
          database error corrections.

9.   Directory Listings and Directory Distribution.  ELI will be required to
     ---------------------------------------------
     negotiate a separate agreement for directory listings and directory
     distribution, except as set forth below, with GTE's directory publication
     company.

     Listings. ELI agrees to supply GTE on a regularly scheduled basis, at no
     --------
     charge, and in a mutually agreed upon format (e.g. Ordering and Billing
     Forum developed), all listing information for ELI's subscribers who wish to
     be listed in any GTE published directory for the relevant operating area.
     Listing information will consist of names, addresses (including city, state
     and zip code) and telephone numbers. Nothing in this Agreement shall
     require GTE to publish a directory where it would not otherwise do so.

     Listing inclusion in a given directory will be in accordance with GTE's
     solely determined directory configuration, scope, and schedules, and
     listings will be treated in the same manner as GTE's listings.

     Distribution.  Upon directory publication, GTE will arrange for the
     ------------
     initial distribution of the directory to service subscribers in the
     directory coverage area at no charge.

     ELI will supply GTE in a timely manner with all required subscriber mailing
     information including non-listed and non-published subscriber mailing
     information, to enable GTE to perform its distribution responsibilities.

                                    VIII-11

10.  Busy Line Verification and Busy Line Verification Interrupt.  Each Party
     -----------------------------------------------------------
     shall establish procedures whereby its operator assistance bureau will
     coordinate with the operator assistance bureau of the other Party to
     provide Busy Line Verification ("BLV") and Busy Line Verification and
     Interrupt ("BLVI") services on calls between their respective end users.
     Each Party shall route BLV and BLVI inquiries over separate inward operator
     services trunks.  Each Party's operator assistance bureau will only verify
     and/or interrupt the call and will not complete the call of the end user
     initiating the BLV or BLVI.  Each Party shall charge the other for the BLV
     and BLVI services at the rates contained in Appendix E, or if there is no
                                                 ----------
     applicable rate listed in Appendix E, at the rates in their respective
                               ----------
     tariffs.

11.  SAG.  GTE will provide to ELI upon request the Street Address Guide at a
     ---
     reasonable charge.  Two companion files will be provided with the SAG which
     lists all services and features at all LSOs, and lists services and
     features that are available in a specific LSO.

12.  Dialing Format Changes.  GTE will provide reasonable notification to ELI of
     ----------------------
     changes to local dialing format, i.e., 7 to 10 digit, by end office.

13.  Operational Support Systems (OSS).  GTE shall provide OSS functions to ELI
     ---------------------------------
     for ordering, provisioning and billing that are generally available as
     described in Appendix H attached to this Agreement.  ELI shall pay GTE for
                  ----------
     access to GTE's OSS functions consistent with processes defined in Appendix
                                                                        --------

                                  COLLOCATION


1.   Physical Collocation.  GTE shall provide to ELI physical collocation of
     --------------------
     equipment pursuant to 47 CFR (S) 51.323 necessary for interconnection or
     for access to unbundled network elements, provided that GTE may provide
     virtual collocation in place of physical collocation, or in some cases deny
     a particular collocation request entirely, if GTE demonstrates to the
     Commission that physical collocation, or perhaps even virtual collocation,
     is not practical because of technical reasons or space limitations, as
     provided in Section 251(c)(6) of the Act.  GTE will provide such
     collocation for purposes of interconnection or access to unbundled network
     elements pursuant to the terms and conditions in the applicable federal and
     state EIS tariffs.  GTE will work with ELI to install collocation
     arrangements within the following schedule:

     (1)  GTE will respond to ELI within 10 days of receipt of a collocation
     application as to space availability and if only the tariff rates are
     applicable.

     (2)  If space is available but additional work beyond the tariff is
     required, GTE will respond to ELI within 30 days of receipt of a
     collocation application with any additional charges (e.g., environmental
     conditioning charges).

     (3)  GTE will begin construction of the collocation space once GTE receives
     50% of the nonrecurring charges from ELI.

     (4)  GTE will complete preparation of the collocation space for ELI within
     90 days after GTE receives 50% of the nonrecurring charges from ELI, absent
     extenuating circumstances beyond GTE's control (e.g., inability to obtain
     necessary equipment from a vendor). ELI shall provide GTE with the
     remaining 50% of the nonrecurring charges upon ELI's acceptance of the
     prepared collocation space.

     (5)  If extenuating circumstances occur, GTE will immediately notify ELI of
     those circumstances, and the Parties will negotiate a mutually acceptable
     in-service date.


     1.1  Space Planning.  In addition to such provisions for space planning and
          --------------
          reservation as may be set forth in the applicable GTE federal and
          state EIS tariffs, the parties agree to the following terms and
          conditions.

          1.1.1  GTE has the right to reasonably reserve space within its
                 central offices for its own use. In order to retain reserved
                 space GTE must provide sufficient documentation and
                 justification for its future use. If GTE denies ELI's
                 application for initial or growth collocation space based on
                 reserving space for GTE's future needs, GTE must demonstrate to
                 the Commission proper justification for GTE's reservation of
                 space.

                                     IX-1
<PAGE>

          1.1.2  GTE will notify ELI if it plans to build an addition to a
                 central office where ELI has collocated facilities, if such
                 addition would result in a material increase of space available
                 for collocation.

          1.1.3  Should ELI submit to GTE a two-year forecast for space planning
                 for collocated facilities in a central office, GTE will, in
                 good faith, consider and discuss such forecast with ELI when
                 considering space planning or utilization decisions for such
                 central office; provided, however that any final space planning
                 or utilization decision shall be made by GTE in its sole
                 discretion in light of GTE requirements.

          1.1.4  Subject to technical feasibility and space limitations, GTE
                 will make available at applicable federal and state EIS tariffs
                 such intraoffice facilities as may be necessary to accommodate
                 projected volumes of ELI traffic, or if GTE cannot provide such
                 facilities in a timely manner, ELI may arrange to have a third-
                 party contractor that is mutually acceptable to ELI and GTE
                 (including ELI if it is an approved GTE contractor) provision
                 the necessary facilities, as long as they meet or exceed GTE
                 standard technical specifications and requirements.

          1.1.5  GTE shall not deny physical or virtual collocation to ELI on
                 the basis of insufficient space to accommodate a collocation
                 request if space could be made available for collocation in the
                 specific central office by removing obsolete and inactive or
                 substantially underutilized GTE transmission or other
                 equipment. If no currently vacant space is available and the
                 removal of such equipment is technically feasible, GTE and ELI
                 shall negotiate in good faith the terms and conditions of
                 removal of such equipment to make space available for
                 collocation, subject to any applicable requirements adopted by
                 the Commission or the FCC.

          1.1.6  In the event that GTE demonstrates to the Commission that
                 insufficient space exists to accommodate ELI's request for
                 physical or virtual collocation in a particular GTE central
                 office, GTE will work with ELI to enable ELI to obtain
                 technically feasible and efficient interconnection or access
                 unbundled network elements. Alternatives include, but shall not
                 be limited to, mounting termination banks on GTE's Main
                 Distribution Frame to which ELI may establish connections with
                 its nearby facilities.

     1.2  Connection to Customer Loops and Ports.  Facilities for cross-
          --------------------------------------
          connection to unbundled loops and ports shall be provided under the
          applicable GTE federal tariff for Special Access Cross Connect, until
          such time as a local tariff applicable to the facilities used for such
          cross-connection is filed.

                                     IX-2
<PAGE>

     1.3  Connection to Other Collocated Carriers.  Subject to technical
          ---------------------------------------
          feasibility and space limitations, ELI may interconnect with other
          carriers collocated at a GTE central office at which ELI has
          collocated facilities; provided, however, that ELI and such other
          carriers must be collocated at the GTE central office for the primary
          purpose of interconnecting with GTE or accessing GTE's unbundled
          network elements.  ELI may interconnect with other carriers collocated
          at a GTE central office.  ELI must provide GTE with written notice of
          such interconnection and shall allow GTE ten (10) Business Days in
          which to elect to provide the facilities necessary to accomplish such
          interconnection.  ELI and the other collocated carriers may provide
          the necessary interconnection facilities only if GTE elects not to
          provide such facilities, or if GTE cannot provision the
          interconnection facilities within thirty (30) calendar days of ELI's
          written notice, or if GTE fails to so elect within the ten (10)
          Business Days after receipt of ELI's written notice.  If GTE elects
          and is able to provide interconnection facilities under this section,
          GTE will provide this cross connection under the GTE federal tariff
          for Special Access Cross Connect, until such time as a local tariff
          applicable to the facilities used for such interconnection facilities
          is filed, or pursuant to rates, terms, and conditions that the Parties
          may negotiate.

     1.4  Choice of Vendor.  ELI may use the vendor of its choice to install,
          ----------------
          maintain and repair equipment within ELI's collocated space.  Access
          by the employees, agents or contractors of such vendor shall be
          subject to the same restrictions on access by employees, agents or
          contractors of ELI imposed under the applicable GTE federal and state
          EIS tariffs, including but not limited to certification and approval
          by GTE.

     1.5  Monitoring.  Subject to technical feasibility and space limitations,
          ----------
          ELI may extend its own facilities for remote monitoring of its
          collocated equipment to its collocated space.  ELI may request that
          GTE provide the facilities necessary for such remote monitoring, at
          which time GTE and ELI will negotiate in good faith the price, terms
          and conditions of remote monitoring by GTE.

     1.6  Phone Service.  Upon ordering collocated space, ELI may order that its
          -------------
          collocation cage be provided with plain old telephone service (POTS)
          commencing at such time as GTE has completed construction of the
          collocated space.  ELI shall pay separately for any ordered POTS
          service.

     1.7  Intraoffice Diversity.  At ELI's request, GTE will provide diversity
          ---------------------
          for ingress/egress fiber and power cables where such diversity is
          available and subject to technical feasibility and space limitations.

     1.8  Proprietary Information.  The Parties shall protect all proprietary
          -----------------------
          information disclosed by ELI in any request for collocation or by GTE
          in response to such request, to the extent required under this
          Agreement and any other non-disclosure

                                     IX-3
<PAGE>

          agreements existing as of the date ELI submits its request for
          collocation space to GTE.

     1.9  Notification of Modifications.  GTE will notify ELI of modifications
          -----------------------------
          to collocation space in accord with the terms of applicable GTE state
          and federal EIS tariffs.  Upon completion of construction of ELI's
          collocation space, GTE may not require ELI to modify its collocation
          space or to pay any of the costs associated with modifications to
          other collocation space.  Additionally, GTE shall notify ELI when
          major upgrades are made to the power plants supporting ELI's
          collocation space or when any central office modification would impact
          any service the Parties provide to each other or to their respective
          end users.  The following shall constitute such major upgrades:

          (a) replacement of a rectifier;

          (b) addition or replacement of a new fusing module;

          (c) addition or replacement of a power distribution unit frame; or

          (d) addition or replacement of modular rectifiers.

     1.10 Drawings.  When ELI orders collocation space, GTE and ELI will hold a
          --------
          GTE/Customer meeting in accord with applicable GTE state and federal
          EIS tariffs.  At such meeting, GTE will provide such drawings of GTE's
          central office facility as may be necessary to adequately depict ELI's
          proposed collocation space.

     1.11 Construction of Space.  GTE will construct ELI's collocation space in
          ---------------------
          accord with the terms and conditions set forth in the applicable GTE
          state and federal EIS tariff.  In the alternative, ELI may arrange for
          a third party contractor that is acceptable to GTE to construct the
          collocation cage enclosure.  Additionally, GTE agrees to the following
          terms and conditions regarding construction of collocated space:

          1.11.1  Space will be constructed in 100 square foot increments, but
                  GTE shall work with ELI to construct space in less than a 100
                  square foot increment if insufficient space exists. The
                  constructed space shall be designed so as to prevent
                  unauthorized access.

          1.11.2  A standard 100 square foot cage shall have the following
                  standard features:

                  (a) eight-foot high, nine gauge chain link panels;

                                     IX-4
<PAGE>

                  (b)  three of the panels listed at (a) above shall measure
                  eight by ten feet, the fourth panel shall measure eight by
                  seven feet;

                  (c)  the door to the cage shall measure eight by three feet
                  and shall also consist of nine gauge chain link;

                  (d)  the cage shall be provided with one padlock set, with GTE
                  retaining one master key;

                  (e)  one ac electrical outlet;

                  (f)  one charger circuit system;

                  (g)  one electrical sub-panel;

                  (h)  such additional lighting as may be necessary;

                  (i)  one fire detection requirement evaluation;

                  (j)  grounding for the cage consistent with COEI.

          1.11.3  Modifications to the standard configuration set forth in
                  Section 1.11.2 can be made on an individual case basis. If
                  modifications are agreed upon and made by the Parties, GTE
                  will work with ELI to implement such additional modifications
                  as may be necessary to ensure that ELI's collocated space is
                  protected from unauthorized access.

          1.11.4  At such time as construction of ELI's collocation space is
                  approximately 50 percent completed, GTE will give ELI
                  notification, and such notification shall include scheduled
                  completion and turnover dates. GTE shall provide ELI with
                  sufficient information to enable the Parties to establish firm
                  CLLI codes and to order cross connections for the equipment
                  ELI intends to locate in the space 30 days prior to the
                  scheduled implementation date. The cross-connect circuits
                  shall be provisioned in conjunction with the installation of
                  the collocation equipment.

          1.11.5  GTE will conduct a walk through of the collocated space with
                  ELI within three (3) business days of completion of
                  construction of collocated space. Should ELI note any
                  deviations from the plan agreed upon by GTE and ELI at the
                  customer meeting, and if such deviations were not requested by
                  ELI or not required by law, GTE shall correct such deviations
                  at its own expense within 5 Business Days.

                                     IX-5
<PAGE>

     1.12 Connection Equipment.  ELI may provision equipment for the connection
          --------------------
          of ELI termination equipment, including but not limited to digital
          loop carriers and associated equipment, to GTE equipment using either
          of the following methods:

          1.12.1  ELI may extend an electrical or optical cable from the
                  terminal within ELI's collocation cage and terminate that
                  cable at GTE's network.

          1.12.2  ELI may install a patch panel within its collocation cage and
                  then hand the cabling to GTE to extend to and have GTE
                  terminate that cable at GTE's network.

     1.13 Access to ELI Collocation Space.  The terms and conditions of access
          -------------------------------
          to CLEC's collocation space shall be as set forth in applicable GTE
          state and federal EIS tariffs.  Additionally, GTE agrees that the
          following terms and conditions shall apply to access:

          1.13.1  GTE shall implement adequate measures to control access to
                  collocation cages.

          1.13.2  Collocation space shall comply with all applicable fire and
                  safety codes.

          1.13.3  Doors with removable hinges or inadequate strength shall be
                  monitored by an alarm connected to a manned site. All other
                  alarms monitoring ELI collocation space provided by GTE shall
                  also be connected to a manned site. ELI may, at its option,
                  provide its own intrusion alarms for its collocated space.

          1.13.4  GTE shall control janitorial access to collocation cages, and
                  restrict such access to approved and certified employees,
                  agents or contractors.

          1.13.5  GTE shall establish procedures for access to collocation cages
                  by GTE and non-GTE emergency personnel, and shall not allow
                  access by security guards unless such access comports with
                  this section and is otherwise allowed under applicable GTE
                  state and federal EIS tariffs.

          1.13.6  GTE shall retain a master key to ELI's collocation space for
                  use only in event of emergency as detailed in applicable GTE
                  state and federal tariffs. At ELI's option, the Parties shall
                  review key control procedures no more frequently than once in
                  any twelve month period. At any time, ELI may elect to change
                  keys if it suspects key control has been lost, provided,
                  however, that GTE will be provided with a master key in accord
                  with this section.

          1.13.7  Not more frequently than once a year, ELI may audit the
                  security and access procedures and equipment applicable to its
                  collocated space and the

                                     IX-6
<PAGE>

               central office housing the collocation space. Access by personnel
               necessary to conduct such an audit shall be limited as set forth
               in applicable GTE state and federal EIS tariffs. Should ELI
               identify deficiencies in security and access procedures and
               equipment as a result of such audit, the cost, terms and
               conditions of the correction of such deficiencies shall be
               negotiated in good faith between the parties.

     1.14 Common Collocation Space.  Where sufficient space exists and upon
          ------------------------
          request, GTE will provide for collocation on a shared or common space
          basis, with each collocator's area defined within the common space.
          Access to the common collocation space will be via a common entry
          point, and each collocator shall be responsible to provide any
          additional security measures to protect its equipment.  To the extent
          not inconsistent with these requirements, the remaining rates, terms,
          and conditions for physical collocation in this Article shall apply to
          common collocation arrangements.

2.   Virtual Collocation.  Subject to Section 1 of this Article, GTE will
     -------------------
     provide virtual collocation for purposes of interconnection or access to
     unbundled network elements pursuant to the terms and conditions in the
     applicable GTE federal and state EIS tariffs.  In addition, the terms and
     conditions set forth in this Section 2 shall apply to virtual collocation
     provided to ELI.

     2.1  Conversion from Virtual to Physical Collocation.  Unless it is not
          -----------------------------------------------
          practical for technical reasons or because of space limitations, ELI
          may convert a virtual collocation arrangement to a physical
          collocation arrangement.  ELI's request to do so shall be treated as a
          new physical collocation request and ELI shall pay GTE at the
          applicable tariff rates for construction and rearrangement of ELI's
          equipment as well as all applicable tariffed physical collocation
          recurring charges.  To the extent technically feasible and efficient,
          GTE shall retain the existing connections between its network and
          ELI's collocated equipment as part of the conversion.

     2.2  Conversion from Physical to Virtual Collocation.  Unless it is not
          -----------------------------------------------
          practical for technical reasons or because of space limitations, ELI
          may convert a physical collocation arrangement to a virtual
          collocation arrangement.  ELI's request to do so shall be treated as a
          new virtual collocation request and ELI shall pay GTE at the
          applicable tariff rates for construction and rearrangement of ELI's
          equipment as well as all applicable tariffed virtual collocation
          recurring charges.  To the extent technically feasible and efficient,
          GTE shall retain the existing connections between its network and
          ELI's collocated equipment as part of the conversion.  If ELI elects
          to change to a virtual collocation arrangement pursuant to this
          section, GTE will not refund previous payments for physical
          collocation received from ELI.  If another carrier occupies the
          physical collocation space vacated by ELI, however, GTE shall remit to
          ELI the net salvage value of the cage enclosure,

                                     IX-7

          ladder racking, and power cabling that was constructed in and up to
          the space ELI vacated.

     2.3  Vendors.  Choice of vendors for equipment used for virtual collocation
          -------
          shall be under the terms and conditions set forth in the applicable
          GTE federal and state EIS tariff.  Upon request by ELI, GTE shall
          provide a list of locally qualified vendors approved for the type of
          equipment to be collocated.  ELI shall not be precluded from
          submitting a request to become an approved contractor with Regional
          Contract Administrators, and GTE shall not deny that request solely on
          the grounds that ELI is a CLEC.

     2.4  Inspection.  Upon provision of virtual collocation by GTE, the Parties
          ----------
          shall agree on a mutually acceptable schedule whereby ELI may inspect
          the equipment in its virtual collocation space.

3.   Fixed Wireless Collocation.  Where technically feasible and upon request,
     --------------------------
     GTE will provide to ELI physical collocation on the roof(s) of GTE central
     office or wire center for fixed wireless equipment necessary for access to
     unbundled network elements or interconnection of ELI's network facilities
     to GTE's network.  GTE shall provide such collocation in accordance with
     its applicable federal and state EIS tariffs.

              ACCESS TO POLES, DUCTS, CONDUITS AND RIGHTS-OF-WAY

To the extent required by the Act, GTE and ELI shall each afford to the other
access to the poles, ducts, conduits and rights of way it owns or controls on
terms, conditions and prices comparable to those offered to any other entity
pursuant to each Party's tariffs and/or standard agreements.  Accordingly, GTE
and ELI shall execute pole attachment and conduit occupancy agreements in the
form set forth in Appendices I and J.

                             RATES AND CHARGES FOR
                      TRANSPORT AND TERMINATION OF TRAFFIC


General.  The rates contained in this Appendix C are the rates as defined in
- -------                               ----------
Article V and are subject to change resulting from future Commission or other
proceedings, including but not limited to any generic proceeding to determine
GTE's unrecovered costs (e.g., historic costs, contribution, undepreciated
reserve deficiency, or similar unrecovered GTE costs (including GTE's interim
Universal Service Support Surcharge)), the establishment of a competitively
neutral universal service system, or any appeal or other litigation.  Any
amendment to this Appendix required as a result of any future Commission or
other proceedings shall be made according to the terms of the final Commission
and/or court order resolving that proceeding.


Each Party  will bill the other Party as appropriate:

A.   The Local Interconnection rate element that applies to Local Traffic on a
     minute of use basis that each Party switches for termination purposes at
     its wire centers.  The local interconnection rate is $0.0058242.

B.   The Tandem Switching rate element that applies to tandem routed Local
     Traffic on a minute of use basis.  The tandem switching rate is $0.0018106.

C.   The Common Transport Facility rate element that applies to tandem routed
     Local Traffic on a per minute/per mile basis.  The Common Transport
     Facility rate is $0.0000044.

D.   The Common Transport Termination element that applies to tandem routed
     Local Traffic on a per minute/per termination basis.  The Common Transport
     Termination rate is $0.0001519.

E.  The Tandem Transiting Charge is comprised of the following rate elements:

     Tandem Switching:                                         =    $0.0018106

     Tandem Transport (10 mile average): 10 x $0.0000044       =    $0.0000440

     Transport Termination (2 Terminations): 2 x $0.0001519    =    $0.0003038

          Transiting Charge:                                        $0.0021584

                                  APPENDIX F
                         PRICES FOR UNBUNDLED ELEMENTS


General. The rates contained in this Appendix F are the rates as defined in
- -------                              ----------
Article VII and are subject to change resulting from future Commission or other
proceedings, including but not limited to any generic proceeding to determine
GTE's unrecovered costs (e.g., historic costs, contribution, undepreciated
reserve deficiency, or similar unrecovered GTE costs (including GTE's interim
Universal Service Support Surcharge)), the establishment of a competitively
neutral universal service system, or any appeal or other litigation. Any
amendment to this Appendix required as a result of any future Commission or
other proceedings shall be made according to the terms of the final Commission
and/or court order resolving that proceeding. This Appendix may be superseded by
the provisions in Article III, Section 46, and Appendices 46A and 46B. At such
time as ELI desires to obtain unbundled ports, local switching, and transport
from GTE, the Parties agree to negotiate the terms and conditions specified in
Article VII, Section 2.2.1 and to amend this Agreement accordingly. ELI shall
not obtain unbundled ports, local switching, and shared transport from GTE until
such amendment becomes effective.

GTE assesses a separate interim universal service fund surcharge for loops and
ports to provide continued universal service support that is implicit in GTE's
current retail services prices; and to respect the careful distinctions Congress
has drawn between access to UNEs, on the one hand, and the purchase at wholesale
rates of GTE services on the other. This surcharge is being addressed (or will
be addressed) by the Commission or a court of competent jurisdiction. The
parties agree that GTE will offer the port and loop UNEs at the rates set forth
below in Appendix F without the interim surcharge, but subject to the following
terms and conditions:

A.   ELI agrees that within thirty (30) days after the effective date of a
     Commission or court order affirming GTE's interim surcharge, ELI will (i)
     begin paying the monthly interim surcharge in accord with Appendix F, and
     (ii) make a lump sum payment to GTE of the total interim surcharges
     retroactive to the effective date of this Agreement.

B.   Notwithstanding any provision in this Agreement, GTE may, at its sole
     discretion and at any time, seek injunctive or other relief (i) requiring
     ELI to pay GTE's interim surcharge or (ii) requiring the Commission to
     immediately impose the interim surcharge.

C.   Nothing in this Agreement shall restrict or impair GTE from seeking
     injunctive relief or any other remedy at any time and in any court
     regarding GTE's interim surcharge or the Commission's rejection or
     modification of GTE's interim surcharge.

                                  APPENDIX H
            SERVICE ORDERING, PROVISIONING, BILLING AND MAINTENANCE


1.   Service Ordering, Service Provisioning, and Billing Systems Generally. The
     ----------------------------------------------------------------------
     following describes generally the operations support systems that GTE will
     use and the related functions that are available for ordering, provisioning
     and billing for resold services, interconnection facilities and services
     and unbundled network elements.  Except as specifically provided otherwise
     in this Agreement, service ordering, provisioning, billing and maintenance
     shall be governed by the GTE Guide.  Before orders can be taken, ELI will
     provide GTE with its Operating Company Number ("OCN") and Company Code
     ("CC") as follows:

     (a)  ELI must provide its OCN (four-digit alpha-numeric assigned by
     Bellcore or number administrator) on the ALEC Profile. The GTE Guide
     provides the necessary information for ELI to contact Bellcore to obtain
     the OCN. There are no optional fields on the Profile.

     (b)  Before the Local Service Request ("LSR") and Directory Service Request
     ("DSR") order forms can be processed ELI must provide the OCN and Customer
     Carrier Name Abbreviation ("CCNA").

     1.1  Operations Support Systems for Trunk-Side Interconnection
          ---------------------------------------------------------

          1.1.1  ELI will be able to order trunk-side interconnection services
                 and facilities from GTE through a direct electronic interface
                 over the GTE Network Data Mover ("NDM") in a nondiscriminatory
                 manner. Orders for trunk-side interconnection will be initiated
                 by an Access Service Request ("ASR") sent electronically by ELI
                 over the NDM. ASRs for trunk-side interconnection will be
                 entered electronically into GTE's Carrier Access Management
                 System ("CAMS") to validate the request, identify any errors,
                 and resolve any errors back to ELI. CAMS is a family of GTE
                 systems comprised primarily of EXACT/TUF, SOG/SOP, and CABS.

          1.1.2  The use of CAMS to support ELI's requests for trunk-side
                 interconnection will operate in the following manner: GTE will
                 route the ASR through its data center to one of two National
                 Access Ordering Centers ("NACC"). The ASR will be entered
                 electronically into the EXACT/TUF system for validation and
                 correction of errors. Errors will be referred back to ELI. ELI
                 then will correct any errors that GTE has identified and
                 resubmit the request to GTE electronically through a
                 supplemental ASR, without

                                      H-1
<PAGE>

                 penalty or charge (e.g., order modification charge) to ELI.
                 Similarly, errors committed by GTE subsequent to the receipt of
                 a valid ASR from ELI will be expeditiously identified and
                 corrected by GTE without the need for ELI's submission of a
                 supplemental ASR. GTE then will translate the ASR into a
                 service order for provisioning and billing.

          1.1.3  At the next system level, translated service orders will be
                 distributed electronically through the SOG/SOP systems to
                 several destinations. The SOG/SOP system will begin the actual
                 provisioning of the service for ELI. Other GTE provisioning
                 systems are CNAS and ACES. The GTE Database Administrative
                 Group ("DBA") and the Special Services Control Center ("SSCC")
                 will be the two most important destinations at this level. The
                 DBA location will identify codes for the appropriate GTE switch
                 in order to provide the functions required by the ASR. The SSCC
                 will provide the engineering for the facilities over which the
                 services will be handled. Information from these two groups
                 (and others) then will be transmitted electronically to GTE's
                 field service personnel (Customer Zone Technicians or "CZTs")
                 who will establish the trunks and facilities, thus connecting
                 the GTE facilities to a connecting company, if one is required,
                 and to ELI. GTE's CZTs also will contact ELI directly to
                 perform testing, and upon acceptance by ELI, will make the
                 necessary entries into the GTE system to complete the order.
                 The completed orders then will pass to GTE's Carrier Access
                 Billing System ("CABS") which will generate the bill to ELI.
                 The billing process under CABS requires coordination with
                 several other systems.

          1.1.4  Billing for transport and termination services cannot be
                 accomplished without call records from GTE's central office
                 switches. Records of usage will be generated at GTE's end
                 office switches or the access tandems. Call usage records will
                 be transmitted electronically from GTE's switches through GTE's
                 Billing Intermediate Processor ("BIP"). This system will
                 collect the call records, perform limited manipulations to the
                 record and transfer them to a centralized data center where
                 they will be processed through the Universal Measurement System
                 ("UMS") to determine the validity and accuracy of the records.
                 UMS also will sort the records and send them to the CABS
                 billing system, from which GTE will produce a bill and send it
                 to ELI.

     1.2  Operations Support Systems for Resold Services and Unbundled Elements
          ---------------------------------------------------------------------

                                      H-2
<PAGE>

          1.2.1  ELI will also be able to order services for resale and
                 unbundled network elements, as well as interim number
                 portability, directly from GTE through an electronic interface.
                 To initiate an order for these services or elements, ELI will
                 submit a Local Service Request ("LSR") from its data center to
                 GTE's Data Center using the same electronic NDM interface used
                 for trunk-side interconnection. If no NDM interface exists or
                 if ELI chooses to establish a separate NDM interface, ELI must
                 request an NDM facility. For new entrants that elect not to
                 interface electronically, GTE will accommodate submission of
                 LSR orders by facsimile, E-mail, Internet or a dial NDM
                 arrangement. An LSR is very similar to an ASR, except that it
                 will be used exclusively for line-side interconnection
                 requests. GTE will transfer LSRs to GTE's NOMC centralized
                 service order processing center electronically.

          1.2.2  Most LSRs will be used either to transfer an existing GTE
                 customer to ELI or to request service for a new customer who is
                 not an existing GTE customer. Depending on the situation,
                 different information will be required on the LSR. LSRs for a
                 conversion of a GTE local customer to ELI must include
                 information relating to all existing, new and disconnected
                 services for that customer, including the customer's name, type
                 of service desired, location of service and features or options
                 the customer desires. ELI will be able to obtain this customer
                 information after GTE has received the customer's written
                 consent as specified in Article VI.3.3. For service to a new
                 customer who is not an existing GTE customer, the LSR must
                 contain the customer's name, service address, service type,
                 services, options, features and ELI data. If known, the LSR
                 should include the telephone number and due date/desired due
                 date.


          1.2.3  While ELI would have its own customer information and may have
                 the SAG/GTE products on tape from GTE, ELI would not have the
                 due date or new telephone number for new customers since that
                 information is contained in GTE's systems. Therefore, a process
                 is required to provide this information to ELI. GTE itself does
                 not have uniform access to this information electronically.
                 Until GTE and ELI have agreed and established electronic
                 interfaces, ELI agrees that a toll free number is the method
                 that will be used. The toll free telephone number will connect
                 ELI directly to GTE's NOMC service representatives. When ELI
                 receives a request for basic services from a new local service
                 customer, ELI will call GTE's NOMC through the toll free
                 number, and, while the new customer is on hold, GTE will
                 provide the due date for service and the new

                                      H-3
<PAGE>

                 telephone number for that customer. At the same time, ELI will
                 give GTE the new customer's name, service address and type of
                 requested service (i.e., R1, B1). GTE will enter that
                 information into its SORCES or SOLAR service ordering systems
                 to be held in suspense until ELI sends the confirming LSR. ELI
                 will then return to its customer holding on the line and
                 provide the due date and new telephone number.

          1.2.4  After concluding the telephone call with the new customer, ELI
                 will complete a confirming LSR for the new service and send it
                 electronically to GTE's data center for processing. Upon
                 receipt, GTE will match the LSR with the service order
                 suspended in GTE's system, and if there is a match, GTE will
                 process the LSR. After the LSR is processed, GTE will transmit
                 confirmation electronically to ELI through the NDM that the LSR
                 has been processed, providing a record of the telephone number
                 and due date. ELI will be required to submit the confirming LSR
                 by 12:00 p.m. each day local time, as defined by the location
                 of the service address. If ELI fails to submit the LSR in a
                 timely manner, the suspended LSR will be considered in
                 jeopardy, at which time GTE will assign a new due date upon
                 receipt of the delayed LSR for such customer requests and
                 notify ELI of the change.

          1.2.5  Number assignments and due date schedules for services other
                 than single line service and hunt groups up to 12 lines will be
                 assigned within approximately twenty-four (24) hours after
                 GTE's receipt of the LSR using the standard Local Service
                 Confirmation ("LSC") report sent electronically to ELI over the
                 NDM, thereby providing a record of the newly established due
                 date. An exception would be a multi-line hunt group for 12
                 lines or fewer. The other numbers then will be provided through
                 the normal electronic confirmation process.

          1.2.6  The processing of specifically requested telephone numbers
                 (called "vanity numbers") is as follows. GTE will work with ELI
                 on a real time interface to process vanity numbers while ELI's
                 customer is still on the line. If a number solution can be
                 established expeditiously, it will be done while the customer
                 is still on the line. If extensive time will be required to
                 find a solution, GTE service representatives will work with ELI
                 representatives off line as GTE would for its own customers.
                 For all of this, the basic tariff guidelines for providing
                 telephone numbers will be followed.

                                      H-4
<PAGE>

          1.2.7  Once the order for line-side interconnection service is
                 established, it is moved for provisioning to the next system
                 level. Here, GTE will validate and process the LSR to establish
                 an account for ELI and, if GTE continues to provide some
                 residual services to the customer, GTE will maintain a GTE
                 account. In GTE's system, GTE's account is called the Residual
                 Account and ELI's account is referred to as the ELI Account. If
                 any engineering for the service is necessary, the account would
                 be distributed to the SSCC. Otherwise, it will be distributed
                 for facility assignment.

          1.2.8  With the account established and any engineering and facility
                 assignment complete, GTE then will transmit electronically a
                 record to GTE's CZT field personnel if physical interconnection
                 or similar activity is required. The CZTs will provision the
                 service and then electronically confirm such provision in the
                 SOLAR/SORCES system when completed. The accounts then will be
                 transmitted to GTE's Customer Billing Services System ("CBSS").
                 GTE shall provide to ELI a service completion report. Call
                 records for actual service provided to ELI's customers on GTE
                 facilities will be transmitted from GTE's switches through some
                 usage rating systems (BIP, UMS), screened and eventually
                 delivered to CBSS for the generation of bills.

          1.2.9  CBSS is a different system than CABS, and it is the one that
                 GTE will utilize to produce the required bills for resold
                 services, unbundled elements and local number portability. CBSS
                 will create a bill to ELI for resold services and unbundled
                 elements along with a summary bill master. Daily unrated
                 records for intraLATA toll usage and local usage (incollect
                 usage data will be provided on rated basis) on ELI's accounts
                 will be generated and transmitted electronically to ELI.

          1.2.10 On resold accounts, GTE will provide usage in EMR format per
                 existing file exchange schedules. The usage billing will be in
                 agreed upon level of detail for ELI to issue a bill to its end
                 users.

          1.2.11 GTE will provide ELI with detailed monthly billing information
                 in a paper format until an agreed upon Electronic Data
                 Interchange 811 electronic bill format is operational.

          1.2.12 State or sub-state level billing will include up to ten (10)
                 summary bill accounts.

          1.2.13  GTE accepts ELI's control reports and agrees to utilize
                  industry standard return codes for unbillable messages.
                  Transmission will occur via the NDM. Tape data will conform to
                  Attachment "A" of the LRDTR. Data will be delivered Monday
                  through Friday except for Holidays as agreed. Data packages
                  will be tracked by invoice sequencing criteria. GTE contacts
                  will be provided for sending/receiving usage files.

          1.2.14  GTE will retain data backup for 45 Business Days.

          1.2.15  In addition to the LSR delivery process, ELI will distribute
                  directory assistance and directory listing information
                  (together sometimes referred to hereafter as "DA/DL
                  information") to GTE via the LSR ordering process over the
                  NDM. GTE will provide listings service via its "listing
                  continuity" offering.

          1.2.16  Charges and credits for PIC changes ordered via an LSR will
                  appear on the wholesale bill. As ELI places a request for a
                  PIC change via LSR, the billing will be made on ELI account
                  associated with each individual end user. GTE will process all
                  PIC changes from IXCs that are received for ELI end users by
                  rejecting back to the IXC with the ELI OCN. Detail is provided
                  so that ELI can identify the specific charges for rebilling to
                  their end user.

          1.2.17  CMDS.  The parties will provide for the distribution of
                  -----
                  intraLATA CMDS incollect messages and/or selected local
                  measured service messages as follows:

                  1.2.17.1  Messages to be Screened. GTE receives CMDS I

                            transmissions containing intraLATA incollect
                            messages from the state RBOC CMDS host each business
                            day. Per ELI's request, GTE will screen the
                            incollects by NPA and line number and accumulate the
                            Collect, Third Number Billed and Credit Card
                            (collectively called incollects) messages in a data
                            file. The screening will be for end users who have
                            chosen ELI as their local service provider through a
                            Resale or Unbundled Network arrangement. The
                            screened incollect messages and any Local Measured
                            Service (LMS) usage will be accumulated and
                            forwarded to ELI. The Parties will mutually agree on
                            the frequency of the data exchange and the method of
                            transmission (i.e., magnetic tape or direct
                            electronic transmission). GTE will forward the
                            screened messages in the industry standard EMR

                            section and will not be screened.

                  1.2.17.2  Compensation.  GTE will bill ELI monthly for all
                            ------------
                            services related to the screening, accumulating,
                            processing and transmitting of incollect messages
                            and LMS usage, if applicable, at a reasonable and
                            mutually agreeable charge. In addition, any message
                            processing fee associated with ELI's incollect
                            messages that are charged to GTE by the CMDS Host
                            will be passed on to ELI on the monthly statement.
                            All revenue, surcharges, taxes and any other amounts
                            due to the CMDS Host for ELI's incollect messages
                            will be billed on the monthly statement. It is ELI's
                            responsibility to bill and collect all incollect and
                            LMS amounts due from its end users. The incollect
                            and LMS revenue amounts that are listed on the
                            monthly invoice are payable to GTE in total. The
                            Parties agree that the arrangement for invoicing the
                            incollect and LMS revenue amounts due GTE is not a
                            settlement process with ELI.

                  1.2.17.3  Administration. The Parties agree to develop a
                            --------------
                            process whereby ELI's end user information is
                            available in a timely manner to allow GTE to build
                            tables to screen the CMDS incollect files and LMS
                            files on behalf of ELI.

          1.2.18  Backbilling.  GTE shall bill ELI on a timely basis.  In no
                  -----------
                  case shall GTE bill ELI for previously unbilled charges that
                  are for more than six months prior to the current bill date.

     1.3  Order Processing.
          ----------------

          1.3.1  Order Expectations.  ELI agrees to warrant to GTE that it is a
                 -------------------
                 certified provider of telecommunications service. ELI will
                 document its Certificate of Operating Authority on the CLEC
                 Profile and agrees to update this CLEC Profile as required to
                 reflect its current certification. The Parties agree to
                 exchange and to update end user contact and referral numbers
                 for order inquiry, trouble reporting, billing inquiries, and
                 information required to comply with law enforcement and other
                 security agencies of the government. The Parties also agree to
                 exchange and to update internal order, repair and billing point
                 of contacts. Prior to submitting an order

                                      H-7
<PAGE>

                 under this Agreement, ELI shall obtain such documentation as
                 may be required by state and federal laws and regulations.

          1.3.2  GTE shall provide ELI with a specified customer contact center
                 for purposes of placing service orders and coordinating the
                 installation of services. These activities shall be
                 accomplished by telephone call or facsimile until electronic
                 interface capability has been established. The Parties adopt
                 the OBF LSR and DSR forms for the ordering, confirmation and
                 billing of resale and unbundled services. The Parties adopt the
                 OBF ASR forms for the ordering, confirmation and billing of
                 trunk-side interconnection.

          1.3.3  GTE will process such service orders during normal operating
                 hours, at a minimum on each Business Day between the hours of 8
                 a.m. to 8 p.m. Eastern Time and shall implement service orders
                 within the same time intervals used to implement service orders
                 for similar services for its own users.

          1.3.4  GTE will provide current GTE customer proprietary network
                 information (name, address, telephone number and description of
                 services provided by GTE including PIC and white page directory
                 listing information) as provided in Article VI, Section 3. The
                 return of customer information will be via facsimile or via
                 electronic transmission.

          1.3.5  Transfer Between Local Service Providers - GTE will provide a
                 displacement/out service report to a Local Service Provider
                 (LSP) whenever an end user leaves that LSP and procures service
                 from another LSP. When an ELI end user changes to another LSP,
                 GTE will notify ELI when such activity occurs.

2.   Maintenance Systems.

     2.1  General Overview

          2.1.1  If ELI requires maintenance for its local service customers,
                 ELI will initiate a request for repair (sometimes referred to
                 as a "trouble report") by calling GTE's Customer Care Repair
                 Center. During this call, GTE service representatives will
                 verify that the end-user is an ELI customer and will then
                 obtain the necessary information from ELI to process the
                 trouble report. While the ELI representatives are still on the
                 line, GTE personnel will perform an initial analysis of the
                 problem and remote line testing for

                                      H-8
<PAGE>

                 resale services. If engineered services are involved, the call
                 will be made to the GTE SSCC for handling. If no engineering is
                 required and the line testing reveals that the trouble can be
                 repaired remotely, GTE personnel will correct the problem and
                 close the trouble report while ELI representatives are still on
                 the line. If on-line resolution is not possible, GTE personnel
                 will provide ELI representatives a commitment time for repair,
                 and the GTE personnel then will enter the trouble ticket into
                 the GTE service dispatch queue. ELI's repair service commitment
                 times will be within the same intervals as GTE provides to its
                 own end users. Maintenance and repair of GTE facilities is the
                 responsibility of GTE and will be performed at no incremental
                 charge to ELI. If, as a result of an ELI-initiated trouble
                 report, trouble is found to be the responsibility of ELI (e.g.,
                 non-network cause) GTE will charge ELI for trouble isolation.
                 ELI will have the ability to report trouble for its end users
                 to appropriate trouble reporting centers 24 hours a day, 7 days
                 a week. ELI will be assigned a customer contact center when
                 initial service agreements are made.

          2.1.2  Repair calls to the SSCC for engineered services will be
                 processed in essentially the same manner as those by the GTE
                 Customer Care Center. GTE personnel will analyze the problem,
                 provide the ELI representative with a commitment time while
                 they are still on the line, and then place the trouble ticket
                 in the dispatch queue.

          2.1.3  GTE then will process all ELI trouble reports in the dispatch
                 queue along with GTE trouble reports in the order they were
                 filed (first in, first out), with priority given to out-of-
                 service conditions. If, at any time, GTE would determine that a
                 commitment time given to ELI becomes in jeopardy, GTE service
                 representatives will contact ELI by telephone to advise of the
                 jeopardy condition and provide a new commitment time.

          2.1.4  Trouble reports in the dispatch queue will be transmitted
                 electronically to GTE CZT service technicians who will repair
                 the service problems and clear the trouble reports. For cleared
                 ELI trouble reports, GTE service technicians will make a
                 telephone call to ELI directly to clear the trouble ticket. GTE
                 service technicians will make the confirmation call to the
                 telephone number provided by ELI. If ELI is unable to process
                 the call or places the GTE technician on hold, the call will be
                 terminated. To avoid disconnect, ELI may develop an answering
                 system, such as voice mail, to handle the confirmation calls
                 expeditiously.

                                      H-9
<PAGE>

          2.1.5  GTE will provide electronic interface access to operation
                 support systems functions which provide the capability to
                 initiate, status and close a repair trouble ticket. GTE will
                 not provide to ELI real time testing capability on ELI end user
                 services. GTE will not provide to ELI an interface for network
                 surveillance (performance monitoring).

          2.1.6  GTE will resolve repair requests by or for ELI local service
                 customers using GTE's existing repair system in parity with
                 repair requests by GTE end users. GTE will respond to service
                 requests for ELI using the same time parameters and procedures
                 that GTE uses. ELI then would call GTE's Customer Care Center
                 or SSCC while the customers were on hold.

     2.2  Network Management Controls.

          2.2.1  Network Maintenance and Management.  The Parties will work
                 ----------------------------------
                 cooperatively to install and maintain a reliable network.

          2.2.2  Neither Party shall be responsible to the other if necessary
                 changes in network configurations render any facilities of the
                 other obsolete or necessitate equipment changes.

          2.2.3  Network Management Controls.  Each Party shall provide a 24-
                 ---------------------------
                 hour contact number for Network Traffic Management issues to
                 the other's network surveillance management center. A fax
                 number must also be provided to facilitate event notifications
                 for planned mass calling events. Additionally, both Parties
                 agree that they shall work cooperatively that all such events
                 shall attempt to be conducted in such a manner as to avoid
                 degradation or loss of service to other end users. Each Party
                 shall maintain the capability of respectively implementing
                 basic protective controls such as "Cancel To" and "Call Gap."

3.   Electronic Interface.  The Parties shall work cooperatively in the
     --------------------
     implementation of electronic gateway access to GTE operational support
     systems functions in the long-term in accordance with established industry
     standards and any FCC and Commission requirements.

     3.1  ELI shall have immediate access to the following OSS electronic
          interfaces that will provide functionality to enable ELI to service
          customers in an equal and non-discriminatory manner:

                                     H-10
<PAGE>

          3.1.1  Pre-Order functions, e.g., TN Assignment, DD Reservation,
                 Address Validation, Product Availability, that are available on
                 a dial-up or dedicated basis using the Secure Integrated
                 Gateway System (SIGS).

          3.1.2  Order functions that are available on a dial-up or dedicated
                 basis using CONNECT:  Mail file transfer.

          3.1.3  Repair functions, e.g., trouble report repair functions, to
                 allow ELI to determine status and close trouble reports.

          3.1.4  Electronic transfer of the ELI bill in electronic data 811
                 format.

     3.2  ELI may migrate to fully interactive system to system
          interconnectivity. GTE, with input from ELI and other carriers, shall
          provide general interface specifications for electronic access to this
          functionality. These specifications will be provided to enable ELI to
          design system interface capabilities. Development will be in
          accordance with applicable national standards committee guidelines.
          Such interfaces will be available as expeditiously as possible.

     3.3  ELI shall pay the costs and expenses for any new or modified
          electronic interfaces ELI requests that are unique to ELI and that GTE
          determines are technically feasible and GTE agrees to develop to the
          extent authorized by the FCC or the Commission; Provided, however, in
          the event that other LECs subsequently request any specific and unique
          interface for which GTE has previously been paid by ELI, for the first
          ten such LECs, GTE shall reimburse ELI for a pro rata portion of the
          amount previously paid by ELI, to the extent GTE is reimbursed by the
          LEC(s) for such interface.  Costs for development of systems intended
          for common use by competing carriers will be assessed pursuant to the
          method of cost recovery authorized or established by the FCC or the
          Commission or based on a mutually agreed method of cost recovery.

     3.4  ELI shall be responsible for modifying and connecting any of its pre-
          ordering and ordering systems with GTE-provided interfaces as
          described in this Appendix.

4.   GTE Initiated Electronic System Redesigns.  GTE will not charge ELI when

                              SERVICE DESCRIPTION

2.1  Provision.  Subject to the terms and conditions of this Appendix, GTE
     ---------
     agrees to provide the Service to ELI.

2.2  Interconnection.  This Agreement is for ELI's interconnection with GTE at
     ---------------
     GTE's __________ STPs to support local exchange services.  ELI shall not
     submit signaling messages in support of interexchange services.

2.3  Service.  The "Service" consists of the following:
     -------

     (a)  Interconnection of GTE's CCS/SS7 network to ELI's CCS/SS7 network is
          via an "A" Link connection between ELI's SP or SSP and GTE's STP.  The
          "A" Link connection is made by a dedicated 56 kbps channel between the
          SP or SSP and the STP.  Any connection from an SSP or an SP to an STP
          pair will have a link to each individual STP (i.e., two (2) links).
          ELI and GTE shall mutually agree upon the location of the SPOI.

     (b)  Interconnection of GTE's CCS/SS7 network to ELI's CCS/SS7 network via
          a "B" Link connection between ELI's STPs and GTE's STPs.  The "B" Link
          connection is a dedicated 56 kbps channel.  Connections between two
          (2) pairs of STPs will have four (4) connections; i.e., one (1) link
          from each individual STP to each individual STP.  ELI and GTE shall
          mutually agree upon the location of the SPOI.

     (c)  Local and IntraLATA call set-up signaling, allowing ELI to use the
          out-of-band trunk signaling provided by GTE's CCS/SS7 network to carry
          its calls on the intraLATA toll network.

     (d)  The Service shall include access to:  (1) all switching systems served
          by a given STP which have been converted to SS7 signaling, including
          switching systems owned by other local service providers; (2)
          databases directly connected to a given STP, with the exception of
          800/888 databases which can be accessed through any STP; (3) other
          local service provider STPs on an intraLATA basis; and (4) other Third
          Party local service provider STPs on an intraLATA basis.

     (e)  It is the responsibility of ELI to populate the "privacy indicator"
          portion of all SS7 signaling messages forwarded to GTE's network.  GTE
          agrees to deliver the information forwarded by ELI in the SS7
          signaling message.  ELI, by entering

                                      I-2
<PAGE>

          into this Agreement, agrees to deliver "privacy indicator" information
          forwarded by GTE in its signaling message.

     (f)  ELI acknowledges that call set-up times may be greater when ELI
          employs intermediate access tandems (IATs) in its network.

     (g)  If selected on the order form attached to this Appendix, the Service
          shall also include IXC call set-up signaling service (ISUP) as
          described in Article 2.4 of this Appendix.  Additional charges as set
          forth in Exhibit A shall apply.

2.4  ISUP Service Charge.  This is an optional service that allows ELI to
     -------------------
     utilize SS7 signaling to an SS7 capable interexchange carrier (IXC) for
     Feature Group D access service and other intraLATA interexchange services.
     The ISUP service is a monthly charge.

     (a)  The rate for ISUP signaling is per connection in situations when GTE
          does not provide any underlying call messages for ELI on GTE's network
          trunks.  The rate for ISUP signaling is shown in Exhibit A.

     (b)  Where GTE has a mated pair of STPs and has CCS/SS7 interconnection
          facilities to an IXC within the same LATA, for interexchange
          telecommunications services, GTE shall provide call set-up signaling
          between ELI and the IXC.

     (c)  ELI agrees to provide to GTE such information as deemed necessary by
          GTE for network planning in connection with this offering and as may
          be requested by GTE from time to time.

     (d)  ELI must provide the Signaling Point Codes of the IXCs for which it is
          providing call setup via GTE's SS7 signaling network, so that GTE
          screening and translation tables can be updated.

2.5  Technical Specifications.  The technical specifications for the Services
     ------------------------
     described above are defined in Bellcore TR-TSV-000905.  GTE will provide
     SS7 via OR-394-SS7 and/or OR-317-SS7 format(s).

2.6  Other Services.  If ELI desires to order SS7-related services other than
     --------------
     the Service, such services will be governed by separate agreements.

2.7  Applicable Traffic.  The Service applies to the traffic of ELI and its
     ------------------
     subtending LECs only.  ELI must provide GTE with thirty (30) calendar days'
     written notice and a letter of agency before the traffic of any party other
     than ELI or its subtending LECs may be transmitted through ELI's facilities
     on to GTE's SS7 network.

                            MANNER OF PROVISIONING

3.1  Link Facilities.  The link facilities to GTE STPs in the same LATA can be
     ---------------
     either:

     (a)  "A" Link sets from ELI's SP or SSP.  A minimum of two (2) links is
          required, one (1) from the SP or SSP to each STP; or,

     (b)  "B" Link sets from ELI's STPs that are connected to GTE's mated pairs
          of STPs.  A minimum of four (4) links is required between the two (2)
          pairs of STPs.

3.2  Port Termination.  An STP port termination 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, F.C.C. No. 4.

3.3  Signaling Point Codes.  GTE shall install all applicable Signaling Point
     ---------------------
     codes for each signaling link at each of GTE's interconnecting STPs.

3.4  Protocol.  GTE shall provision the Service in accordance with ANSI T1.226
     --------
     Telecommunications - Operations, Administration, Maintenance, and
     Provisioning (OAM&P) -Management of functions for Signaling System No. 7
     (SS7) Network Interconnections (ATIS) with the exception of references to
     OMAP protocol elements.  The Service cannot be established until
     Compatibility Testing has been successfully completed between ELI and GTE.

3.5  56 kbps Channel.  Unless ELI elects to provide such links, GTE shall
     ---------------
     provide two (2) or four (4) 56 kbps circuits as link facilities at rates
     set forth in Article 4 herein.  If approved by GTE, ELI may utilize a 56
     kbps channel of an intraLATA DS1 (1.544 mbps) facility, which is in place
     at the time of ordering, as an "A" Link or a "B" Link, for the STP access
     connection between the SPOI and GTE's STP.  WHEN THIS OPTION IS CHOSEN, ELI
     UNDERSTANDS AND ACCEPTS THAT THE SERVICE PERFORMANCE STANDARDS AS OUTLINED
     IN BELLCORE DOCUMENT TR-TSV-000905 MAY NOT BE MET IN THE PROVISION OF THE
     TOTAL SERVICE.  If such a channel is not utilized, ELI must order DS1
     (1.544 Mbps) service.

3.6  Multiplexing.  Where technically required, GTE shall provide multiplexing
     ------------
     arrangements to ELI at no charge.

3.7  Diversity.  Where technically feasible and not unreasonably economically
     ---------
     burdensome, GTE agrees to allow interoffice and intraoffice diversity.

Note: Outage Credits: Local Service and Unbundled Network Elements: Outage
Credits apply to interruptions of Local Services and Unbundled Network Elements
in accordance with applicable Commission requirements. If a Local Service or
Unbundled Network Element is interrupted, ELI will be entitled to outage
credits. An interruption period begins when ELI reports to GTE that a Local
Service or Unbundled Network Element is interrupted (or GTE has knowledge that
an interruption has occurred through service monitoring or other means). An
interruption period ends when the Local Service is repaired and returned to ELI.
A Local Service or Unbundled Network Element is considered to be interrupted
when there has been a loss of continuity, the Local Service or Unbundled Network
Element does not operate in accordance with the applicable service standards, or
it is otherwise unavailable for use by ELI. This definition is not intended to
conflict with Commission requirements.

                              less than fully leased and occupied, Taxes shall
                              include an amount representing the estimated taxes
                              that Landlord would incur if the Building was
                              fully leased and occupied, as determined by
                              Landlord in a reasonable, customary and commonly

     2.   Premises; Term.
          --------------

          (a)  Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord the Premises, for the Term and upon the conditions, covenants, and
agreements hereinafter set forth.

                                       8

          (b)  Subject to paragraph 17 hereof Tenant shall have a nonexclusive
right to use the Common Areas and Facilities of the Building which lead to and
from the Premises and other areas shared with other tenants in the Building.
Nothing herein contained shall be construed as a demise to Tenant of the roof,
exterior walls of the Building, space outside the Premises, air rights above or
outside of the Premises, or of the Common Areas and Facilities.

          (c)  Landlord warrants that it is the lawful tenant under that certain
ground lease dated July 22, 1969 and recorded on July 22, 1969, as instrument
no. 734560 in Book 1166 at page 140 of the Official Records of Adams County,
Colorado and that the term of such ground lease has been extended to a date that
extends beyond the time of the Term, as extended, if at all, pursuant to Section
60 of this Lease.

     3.   Possession/Tenant Improvements.  All work and items not within the
          ------------------------------
scope of the Landlord Improvements to be furnished and installed in the Premises
(the "Lessee Improvements"), such as furniture, furnishings, equipment and
telephones, shall be furnished and installed by Tenant at Tenant's expense.
Tenant shall adopt a schedule compatible with the schedule of Landlord's
contractors and shall conduct its work in such a manner and at times as not to
unreasonably interfere with or delay the work of Landlord's contractors. Tenant
shall not begin installing Tenant Improvements without Landlord's prior approval
of Tenant's contractors, subcontractors and all materials and items to be used
for and incorporated in Tenant Improvements, which approval shall not be
unreasonably withheld. Subject to the preceding requirements, Landlord shall
complete items 1, 6 and 8 under "Construction/Demolition" in Exhibit "E" on or
before January 15, 2000 and give access and entry to the Premises to Tenant and
its contractors and subcontractors for installation of the Tenant Improvements
not later than January 1, 2000. If entry is prior to the Commencement Date, the
entry shall be subject to all the terms and conditions of this Lease except the
payment of Base Rent.

     4.   Rent. Tenant shall pay Landlord the Rent, without deduction or offset,
          ----
in advance, on or before the tenth day of each calendar month during the Term,
at Landlord's Mailing Address, or at such other place as Landlord may from time
to time designate in writing. The first month's Base Rent shall be paid upon
execution hereof. The installment of Rent payable for any partial calendar month
shall be prorated based upon a 30-day calendar month. Checks delivered in
payment of Rent shall not constitute payment until paid by the drawee. Tenant
however shall not be responsible for delays in the collection of checks caused
by the Landlord, Landlord's bank or the clearing house. Delivery of a check by
the tenth (10) of a month which is promptly paid in the ordinary course of
business shall satisfy the payment requirements of this section. The covenant to
pay Rent hereunder is independent of any other covenant contained in this Lease.

     5.   Rent Escalation.
          ---------------

          (a)  There shall be added to the Base Rent for each Comparison Year,
     Tenant's Share of the net aggregate increase, if any, in the amount of
     Operating Expenses and Taxes for the Comparison Year over those for the
     Base Year. The Base Rent as so increased is herein referred to as the
     "Adjusted Base Rent". The Adjusted Base Rent for any Comparison Year shall
     serve as the basis for an estimate of Adjusted Base Rent due for the next
     Comparison Year until the computation for that Comparison Year has been
     made. The difference between the actual increase in Operating Expenses and
     Taxes for any Comparison Year and the estimated Adjusted Base Rent for such
     Comparison Year shall be promptly paid by Tenant upon Tenant's receipt of a
     statement of such adjustment. After the Adjusted Base Rent has been
     established, it shall retroactively become payable from the beginning of
     the calendar year. The remaining monthly Rent installments shall be
     adjusted accordingly. Amounts due for any partial year of the Term in
     accordance with the foregoing shall be prorated on a calendar year basis.
     Additionally, within one hundred twenty (120) days after the end of the
     Base Year, Landlord will submit to Tenant for Tenant's review the
     compilation of the Operating Expenses and Taxes, adjusted as required in
     this Lease, for the Base Year. After receipt of such statement, Tenant will
     have one hundred twenty (120) days to dispute any item in the statement or
     manner of calculation of the Operating Expenses and Taxes.

          With respect to Taxes, the statement of adjustment shall reflect, as
     of the date prepared, Taxes incurred for the Base Year and for the
     Comparison Year, whether the same shall be definitive or subject to
     subsequent revision. Should Taxes for the Base Year or any Comparison Year
     be subsequently reduced or increased, Landlord shall recompute the Taxes
     using the amount of the Taxes for the Base Year as so reduced or increased
     for all Comparison Years prior to the Comparison Year in which the
     reduction or increase is granted. In the event of any tax abatements, tax
     phase-in or other similar tax programs that result in an artificially
     lowered tax amount for the Base Year, the tax amount established for the
     Base Year will be increased to reflect the amount that would have been
     expended in the absence of such programs. All changes to Adjusted Base Rent
     due from Tenant by reason thereof shall be payable within thirty (30) days
     after Tenant's receipt of the statement therefor.

          (b)  Landlord shall, during Landlord's regular business hours, make
     available to Tenant records, in reasonable detail, of Operating Expenses
     and Taxes for the period covered by such statement or statements, for a
     period of ninety (90) days after the mailing of such statements to Tenant.
     If Tenant shall not dispute any item in any such statement within thirty
     (30) days following Tenant's receipt of such statement, Tenant shall be
     deemed to have waived any objection thereto.

     6.   Security Deposit.
          ----------------

          (a)  Tenant has deposited with Landlord the Security Deposit, the
     receipt of which (if by check subject to collection) is hereby
     acknowledged. The Security Deposit

                                       10
<PAGE>

     shall be held by Landlord, without liability for interest thereon, as
     security for full performance due of Tenant under this Lease. Upon
     expiration of the Term and written request therefor, the Security Deposit
     shall be returned to Tenant, unless Landlord has reasonable cause to
     withhold all or a portion thereof.

          (b)  If any Rent shall be overdue and unpaid, or should Landlord have
     made payments on behalf of Tenant, or should Tenant fail to perform any of
     the covenants or agreements of this Lease, then Landlord may, without
     prejudice to any other remedy which Landlord may have, apply all or a
     portion of the Security Deposit toward the payment of Rent, or toward any
     loss, damage or expense sustained by Landlord resulting therefrom. In such
     event Tenant shall forthwith restore the Security Deposit to the original
     sum.

          (c)  In the event bankruptcy, insolvency, reorganization or other
     creditor-debtor proceedings shall be instituted by or against Tenant, its
     successors or assigns, or any guarantor of Tenant hereunder, the Security
     Deposit shall be deemed to be applied first to the payment of Rent due to
     Landlord for all periods prior to the institution of such proceedings.

          (d)  In the event that Landlord's interest in the Premises is sold,
     transferred or assigned, Landlord shall deliver the Security Deposit to the
     acquirer of such interest. Thereupon, Landlord shall be discharged and
     released from all further liability with respect to the Security Deposit
     and Tenant agrees to look solely to the new landlord for the return of the
     Security Deposit. This provision shall also apply to any subsequent
     transferees. No holder of a mortgage or deed of trust or lessor under a
     ground or underlying lease to which this Lease is or may be superior or
     subordinate shall be held responsible in connection with the Security
     Deposit, unless it has received the Security Deposit.

     7.   Personal Property and Business Taxes.  Tenant shall pay, prior to
          ------------------------------------
delinquency, all taxes assessed against or levied upon fixtures and all property
of Tenant located in the Premises.  When possible, Tenant shall cause said
fixtures and property to be assessed and billed separately from the real
property of which the Premises form a part.  In the event any or all of Tenant's
fixtures and property shall be assessed and taxed against Landlord, Tenant shall
pay said taxes within ten (10) days after receipt of a written statement setting
forth the amount of taxes applicable to Tenant's fixtures and property.  Tenant
shall pay, prior to  delinquency, all license fees and taxes imposed upon the
business of Tenant.

     8.   Use. Absent the prior written consent of Landlord, Tenant shall not
          ---
use the Premises other than for the Permitted Use.  Tenant shall not use the
Premises in violation of any law or of the certificate of occupancy issued for
the Building.  Within five (5) days of receipt of a notice from  Landlord,
Tenant shall discontinue any use of the Premises which is declared unlawful or
which imposes any duty upon Landlord.  Tenant shall not permit anything to be
done which will invalidate or increase the cost of insurance covering the
Building or property located therein.  Tenant shall, upon demand, reimburse
Landlord for any additional premium charged by reason of Tenant's failure to
comply with the provisions hereof.

     9.   Alterations and Improvements.  Except as may be provided in the "Work
          ----------------------------
Letter" attached hereto as Exhibit "E" and made a part hereof, or as otherwise
provided in this Lease, Landlord shall not be required to alter or improve the
Premises or the Building.  Tenant accepts the Premises in an "as is" condition
and agrees to perform alterations or improvements to the Premises in accordance
with plans and specifications prepared by a certified architect, all at Tenant's
sole cost and expense, subject to Landlord's prior approval, and in accordance
with all applicable laws, ordinances, rules and regulations. Prior to commencing
any alteration or improvement to the Premises, Tenant shall forward to Landlord
three (3) sets of blueprints and one (1) set of sepias of Tenant's proposed
work, and Landlord will complete its review of Tenant's plans within three (3)
business days.  Landlord may in its sole discretion impose requirements as to
the manner of performance of any work by or for Tenant in the Premises.  All
work shall be performed in a good and workmanlike manner using quality material
and shall be promptly completed, lien-free,  by a contractor who is insured,
bonded and has been pre-approved by Landlord. Prior to the commencement of such
work, Tenant or Tenant's general contractor agrees to deliver to Landlord a
Certificate of Worker's Compensation insurance in statutory limits from each
contractor and subcontractor as well as evidence of automobile insurance,
including "non-owned" automobiles, covering personal injury, bodily injury and
property damage, including death resulting therefrom, in the combined single
limit amount of $1,000,000.00 and comprehensive general liability in the
combined single limit amount of $1,000,000.00, with Landlord listed as an
additional named insured.

     Tenant shall provide Landlord with properly completed lien waivers executed
by Tenant's general contractor and, as to labor and materials valued in excess
of $5,000.00, by every subcontractor, including sole proprietorships,
participating in Tenant's work, and every material supplier delivering materials
directly to the Premises.

     10.  Ownership of Improvements.
          -------------------------

          (a)  All alterations and improvements in the Premises made by either
     party (except to Tenant's personal property, furniture and furnishings,
     signs and trade fixtures) shall become the property of Landlord and shall
     be surrendered with the Premises as provided for herein.

          (b)  Tenant shall have the option to remove, at Tenant's sole cost and
     expense, and retain all of Tenant's owned or leased telecommunications
     equipment, telecommunications switches, antennas, computer hardware, fiber
     cables and other fiber optic transmission facilities, transmission
     equipment, machinery, equipment, air conditioning components, furniture,
     and other tangible personal property including dies, tools, jigs, and

     limitation of the foregoing the Tenant can remove:

          (1)  All, equipment and machinery installed by Tenant;

          (2)  all HVAC equipment, provided that Tenant's contractors shall

               has been located

                                       12
<PAGE>

               to a condition at least as good as received, normal wear and tear
               excepted and may remove all associated work if requested by
               Landlord, which may include ducting, electrical runs and
               enclosures, all at Tenant's sole cost and expense;

          (3)  All ALCATEL and DSC switch equipment and associated peripheral
               equipment, all transmission switch equipment, patch panel and
               associated cables, co-location cabinets and associated equipment,
               all electrical equipment associated with this equipment and
               including all battery and UPS power plant equipment;

          (4)  All generators, fuel tanks and associated piping and sound
               control gear and associated conduit and cable.

          (5)  The FM200 dry fire suppression system including the gas
               containers, controls and all cable and control boxes. Tenant
               shall not remove the sprinkler piping and nozzles.

          Tenant shall repair and restore any damage to the Building or Premises
     caused by the removal of any such property.

     11.  Repairs.
          -------

          (a)  Landlord shall maintain and keep in good repair the Building,
     including the roof, exterior walls, all mechanical systems in the Building,
     the parking lots, and the floors, ceilings, and perimeter walls but
     excluding Tenant's HVAC equipment. In the event the necessity for such
     repairs shall have been occasioned by Tenant or any permitted subtenant or
     licensee of Tenant, or their respective employees, agents, contractors or
     any person, firm or corporation acting on its behalf, Tenant agrees to make
     such repairs at Tenant's sole cost and expense. Except in cases of an
     emergency, Landlord shall not be required to commence any repair until
     after receipt of written notice from Tenant. Tenant shall allow Landlord
     reasonable time in which to commence and complete such repairs. Landlord
     shall use reasonable efforts to make such repairs with a minimum of
     inconvenience, disruption, or loss of business to Tenant.

          (b)  Except as provided in subparagraph (a) of this paragraph, Tenant
     agrees to keep and maintain the Premises, the fixtures and equipment
     therein and the appurtenances thereto in good repair and condition at
     Tenant's own cost and expense, and to make all necessary repairs and
     replacements thereto. Tenant shall arrange and pay for all janitorial
     services required for the Premises. Tenant shall keep and maintain the
     Premises in a first-class condition throughout the Term. Tenant shall
     replace all damaged glass with glass of equal quality. In the case of
     damage or destruction by insurable casualty or by eminent domain, the
     obligations of Landlord and Tenant shall be controlled as hereinafter
     provided.

                                       13
<PAGE>

          (c)  Following initial construction of the Premises Tenant may, at its
     own cost, paint, paper or change floor coverings, or otherwise alter the
     Premises, provided that (i) the structural integrity or value of the
     Building shall not be adversely affected and (ii) the cost of such
     alteration does not exceed Five Dollars ($5.00) per square foot; and,
     except as otherwise permitted herein, the sprinkler system is not thereby
     affected. In all other instances, Tenant shall secure prior written
     approval of Landlord. Tenant shall submit to Landlord plans and
     specifications for such proposed work, together with the name of the
     contractor and a statement of the estimated cost thereof. Prior to starting
     such work, Tenant agrees to deliver to Landlord a certificate of worker's
     compensation insurance in statutory limits from Tenant's contractor as well
     as evidence of insurance coverages to be maintained by Tenant hereunder.
     Such work shall be promptly completed in accordance with such approved
     plans and specifications, applicable laws and ordinances, and rules and
     requirements of Landlord's insurance carriers, subject to the terms of
     Tenant's indemnity set forth under paragraph 16 hereof and Tenant's
     obligation to insure such liability under paragraph 28 hereof.

          (d)  The term "repairs" shall include repairs, replacements, renewals,
     alterations, additions, improvements and betterments.

          (e)  If Tenant shall fail or refuse to make repairs as set forth
     above, or if Landlord is required to make any repairs because of any act or
     omission of Tenant (or Tenant's permitted subtenant, business invitee or
     licensee, or their respective employees, agents or contractors, or any
     person, firm or corporation acting on Tenant's behalf), Landlord shall have
     the right, but not the obligation, upon ten (10) days' notice (except in
     case of an emergency), to enter upon the Premises to make such repairs, and
     add the cost thereof to the next installment of Rent due.

     12.  Building Services.  Landlord shall furnish to the Premises water for
          -----------------
lavatory and drinking purposes.

     Except as otherwise expressly provided in this Lease, Tenant shall comply
with all rules and regulations which Landlord establishes for the protection of
Building services, including but not limited to those rules and regulations set
forth on Exhibit "G" attached hereto. Such rules and regulation shall not
conflict with any provision of this Lease and shall be enforced to all tenants
uniformly. Landlord shall have free access to all mechanical installations of
Landlord at all times. Where failure to furnish any of said utilities or
services is caused by strikes, accidents, or conditions beyond the control of
Landlord, Landlord's failure shall neither be deemed an eviction or disturbance
of Tenant's use or possession of the Premises, nor shall such failure render
Landlord liable to Tenant, nor relieve Tenant of its Lease obligations.

     Except as otherwise expressly provided in this Lease, Tenant agrees not to
use any apparatus or device which may increase the amount of such services
usually furnished to the Premises without the prior written consent of Landlord.
Landlord reserves the right to charge for such increased services.

                                       14
<PAGE>

     Landlord reserves the right, without being liable to Tenant and without
abatement or diminution in Rent, to suspend, delay or stop any of the services
to be furnished and provided by Landlord whenever necessary due to any cause
beyond Landlord's control, or for emergency, inspection, cleaning, repairs,
replacements, alterations, improvements or renewals that in Landlord's judgment
are desirable or necessary; and Landlord may suspend any of those services until
completion of any work or until the cause of the suspension has been removed.
Failure by Landlord to any extent to furnish any defined services, or any
cessation of services due to any causes described in the preceding sentence,
shall not render Landlord liable in any respect for damages to either person or
property, nor be construed as an eviction of Tenant, nor work an abatement of
Rent, nor relieve Tenant from fulfillment of any covenant or agreement of this
Lease. Should any of the equipment or machinery utilized in supplying the
services break down, or for any cause cease to function properly, Landlord shall
use reasonable diligence to repair the same promptly, but Tenant shall have no
right to terminate or repudiate this Lease, and shall have no claim for rebate
or abatement of rent or damages, on account of any resulting interruptions in
service.

     13.  Electrical Current.  Electric service to the Premises shall be
          ------------------
separately metered. Tenant shall pay to its electric utility provider the cost
of the consumption of electrical service used in the Premises, calculated at the
rate chargeable to Tenant by the local utility company, as provided in Tenant's
contract with the local utility company.

     Tenant covenants and agrees that its use of electric current shall never
exceed the capacity of the feeders to the Premises, as to be provided pursuant
to Exhibit "E," the Building, the risers or wiring installations. Tenant shall
make no alteration to electrical service equipment supplying primary power to
the Premises without obtaining the prior written consent of Landlord in each
instance.

     14.  Access.  Only after no less than 24-hour notice to Tenant and only by
          ------
accompaniment at all times by an employee of Tenant, Landlord and its agents
shall have the right to enter the Premises for the purpose of inspecting the
Premises, showing the Premises to prospective mortgagees or purchasers of the
Building, and  making alterations, repairs, improvements or additions to the
Premises or to  the Building for any purpose.  Notwithstanding the foregoing,
Landlord acknowledges that Tenant maintains and operates sensitive equipment in
the Premises, and, accordingly, Landlord will make its best efforts to minimize
interference with Tenant's equipment in the event Landlord enters the Premises
to make the aforementioned alterations, repairs, improvements or additions, to
inspect the Premises or to show the Premises to prospective mortgagees or
purchasers, or, in the case of the last six months of the Term, or any extended
term, to show the Premises to prospective tenants.  Except as provided in the
preceding sentence or upon Tenant's consent, Landlord is not permitted to enter
the Premises with prospective tenants during the Term or any extension thereof.
During the six (6) months prior to the end of the Term, or any extended term,
Landlord may show the Premises to prospective tenants.  In the event of an
emergency, if Tenant's representative shall not be present when such an entry by
Landlord is necessary or permitted hereunder, Landlord may enter by means of a
master key or may, after  reasonable attempts to notify Tenant, enter forcibly
without liability to Tenant, except for any failure to exercise due care for
Tenant's property.  Landlord shall neither be deemed guilty of an

                                       15
<PAGE>

eviction or disturbance of Tenant's use and possession of the Premises nor shall
Landlord be liable to Tenant in any manner on account of any entry permitted
hereunder.

     15.  Inability to Perform.  This Lease and the obligations of Tenant
          --------------------
hereunder shall not be affected because Landlord is unable to fulfill any of its
obligations hereunder or is delayed in doing so, if such inability or delay is
caused by reason of any cause beyond the control of Landlord.

     16.  Indemnification.
          ---------------

          (a)  Indemnity by Tenant. Tenant agrees to indemnify, defend, pay, and
               -------------------
     save Landlord harmless from and against any and all claims, demands, suits,
     actions, proceedings, liability, damages, penalties, orders, decrees,
     judgments, costs and expenses arising out of (a) loss of life or injury to
     person or property sustained by anyone in and about the Premises, except
     those resulting from the affirmative act or negligence of Landlord or
     Landlord's officers, agents or employees, and (b) the use or occupancy of
     the Premises by Tenant, its agents and employees in or on the Premises and
     the approaches thereto, or arising or alleged to have arisen out of the
     acts or omissions of Tenant's officers, agents, employees, or invitees and
     Tenant shall, at its own cost and expense, defend any and all suits or
     actions which may be brought against Landlord or to which Landlord may be
     made a party upon any such claims.  Except for the affirmative act or
     negligence of Landlord, its agents, servants or employees, all of Tenant's
     property upon the Premises shall be there at Tenant's sole risk, and
     Landlord shall not be responsible or liable for any damage or injury to any
     property, fixtures equipment or furniture, or to any person or persons, at
     any time upon the Premises.

          (b)  Indemnity by Landlord. Landlord agrees to indemnify, defend, pay,
               ---------------------
     and save Tenant harmless from and against any and all claims, demands,
     suits, actions, proceedings, liability, damages, penalties, orders,
     decrees, judgments, costs and expenses arising out of loss of life or
     injury to person or property sustained by anyone on the Common Areas or the
     Building (exclusive of the Premises), but only to the extent Tenant is not
     liable to indemnify Landlord pursuant to Section 16(a) hereof and only
     during such period as same are under the control of and are being
     maintained by Landlord, except those resulting from the affirmative act or
     negligence of Tenant or Tenant's officers, agents or employees, and
     Landlord shall, at its own cost and expense, defend any and all suits or
     actions which may be brought against Tenant or to which Tenant be made a
     party upon any such claims.  Except for the affirmative act or negligence
     of Tenant, its agents, servants or employees, all of Landlord's property
     upon the Common Areas or the Building (exclusive of the Premises) shall be
     there at Landlord's sole risk, and Tenant shall not be responsible or
     liable for any damage or injury to any property, fixture or Buildings, or
     to any person or persons, at any time upon the Common Areas or the Building
     (exclusive of the Premises). Tenant releases Landlord from all liability
     for any damage to property entrusted to employees of the Building, and for
     injury to persons or for loss of or damage to any property by theft or
     otherwise, unless caused by or due to the gross negligence of Landlord, its
     agents, or employees.  Neither Landlord nor its agents shall be

                                       16
<PAGE>

     liable for interference with light or other intangible rights, nor for any
     latent defect in the Premises or in the Building.

          (c)  Notification of Claims.  Each party hereto shall promptly notify
               ----------------------
     the other of any claim asserted against such party with respect to which
     such party is indemnified against loss by the other party hereunder, and
     the party giving such notice shall promptly deliver to the other party the
     original or a true copy of any summons or other process, pleading, or
     notice issued or served in any suit or other proceeding to assert or
     enforce any such claim.  The party so notified shall, as set forth above,
     defend any such suit at its sole cost and expense with experienced and
     competent attorneys of its own selection, but the party so indemnified
     shall have the right, if it sees fit, to participate in such defense at its
     own expense.

     17.  Rights of Landlord. Landlord reserves the following rights: (a) to
          ------------------
change the name of the Building without notice or liability to Tenant; (b)  to
designate all sources furnishing sign painting or lettering and restroom
supplies used on the Premises; (c) if Tenant vacates the  Premises at any time
during the last ninety (90) days of the Term, to decorate, remodel, repair,
alter or otherwise prepare the Premises for reoccupancy; (d) to maintain pass
keys to the Premises; (e) to grant to anyone the exclusive right to conduct any
particular business in the Building; provided that such exclusive right does not
restrict Tenant's allowed uses of the Premises, as provided by this Lease; and
(f) at any time, at Landlord's expense, to decorate or make repairs,
alterations, additions or improvements, in or to the Building or any part
thereof, including the Premises, including  specifically the right to alter,
improve or rebuild the Common Areas and Facilities.  Except where resulting from
the gross negligence of Landlord, Landlord shall not be liable to Tenant for any
expense, injury, loss or damage resulting from any work so done in or about the
Premises or the Building.

     In connection with making repairs, alterations or additions hereunder,
Landlord shall have the right to post necessary notices on the Premises, and
shall have right of access through the Premises, as well as the right to take
materials that may be required to perform the foregoing into and through the
Premises, as well as the right in the course of such work to close entrances,
doors, corridors, elevators, or other Building facilities or temporarily to
abate the operations of such facilities, without being deemed or held guilty of
an eviction of Tenant and without liability to Tenant.   Rent shall not abate
while the foregoing is being performed and Tenant shall not be entitled to
maintain any offset or counterclaim for damages of any kind against Landlord by
reason thereof, all such claims being hereby expressly released by the Tenant.
All such work shall be done in such manner as to cause Tenant the least
inconvenience practicable

     18.  Assignment and Subletting. Tenant shall not, without the prior written
          -------------------------
consent of Landlord assign, convey, mortgage or sublet this Lease or any
interest herein, or allow any transfer hereof. Any assignment, conveyance,
mortgage or sublease shall be subject to terms and conditions acceptable to
Landlord.  As provided in Paragraph 64 hereof, the location of equipment of co-
locators on the Premises shall not be considered an assignment or subletting of
the Premises and shall not be subject to a Percentage Payment (as defined
hereinafter) so long as such contracts do not purport to lease any part of the
Premises or assign any interest in this Lease.

                                       17
<PAGE>

     Notwithstanding anything to the contrary contained in the preceding
paragraph, Tenant may assign this Lease or sublease the Premises without
Landlord's consent to any entity which controls, is controlled by or is under
common control with Tenant or any entity resulting from any merger or
consolidation with Tenant ("Affiliate"), provided at the time of such transfer
Tenant is not in default hereunder, such assignee assumes all of the terms and
conditions of this Lease, and that Tenant is not released or relieved of any
liability hereunder.

The following shall apply in the case of an approved assignment or sublease:

          (a)  Tenant shall pay to Landlord as Rent under this Lease 75% of the
     Profit (the "Percentage Payment") on such transaction, except for
     assignments and subleases to an Affiliate as and when received by Tenant,
     unless Landlord gives written notice to Tenant and the assignee or
     subtenant that the Percentage Payment shall be paid by the assignee or
     subtenant to Landlord directly.  The "Profit" means (A) all amounts paid to
     Tenant for such assignment or sublease, including monthly rent in excess of
     the monthly rent payable under this Lease, and all fees and other
     consideration paid for the assignment or sublease, including fees under any
     collateral agreements, less (B) costs and expenses directly incurred by
     Tenant in connection with the execution and performance of such assignment
     or sublease for real estate broker's commissions, the cost of lease
     concession, legal fees, and costs of renovation or construction of tenant
     improvements required under such assignment or sublease.  Tenant is
     entitled to recover such costs and expenses before Tenant is obligated to
     pay the Percentage Payment to Landlord.  The Profit in the case of a
     sublease of less than all the Premises is the rent allocable to the
     subleased space as a percentage on a square footage basis.

          (b)  Tenant shall provide Landlord a written statement certifying all
     amounts to be paid from any assignment or sublease of the Premises within
     thirty (30) days after the transaction documentation is signed, and
     Landlord may inspect with prior written notice Tenant's books and records
     to verify the accuracy of such statement.  On written request, Tenant shall
     promptly furnish to Landlord copies of all the transaction documentation,
     all of which shall be certified by Tenant to be complete, true and correct.
     Landlord's receipt of the Percentage Payment shall not be a consent to any
     further assignment or subletting.

     19.  Damage or Destruction.  If the Premises or the Building are damaged by
          ---------------------
fire or other casualty insured under policies of insurance carried by Landlord,
the damage to the Building shall be diligently repaired by and at the expense of
Landlord and the damage to the Premises shall be diligently repaired by and at
the expense of Landlord and Tenant to the extent of their respective obligations
to maintain and repair the Premises pursuant to paragraph 11 hereof, provided
such repairs can, in Landlord's opinion, be made within fifteen (15) days after
the  occurrence of such damage without the payment of overtime or other
premiums.   There shall be no abatement of Rent by reason of any portion of the
Premises being unusable for a period of fifteen (15) days or less.  If the
damage is due to the fault or neglect of Tenant or its employees, agents, or
contractors there shall be no abatement of Rent.

                                       18
<PAGE>

     If repairs cannot be made, in Landlord's reasonable, opinion within the
fifteen (15) day period and without the payment of overtime or other premiums,
Landlord shall have a reasonable time to make the repairs provided that Landlord
has given Tenant a notice within ten (10) days after the incident causing the
damage giving the estimated time to repair.  In such event the Rent shall be
prorated for the period and to the extent the Premises are not able to be used
by Tenant

     If the damage to the Building disrupts Tenant's switch operations and
cannot be repaired by Landlord following telephonic notice to Landlord within 24
hours from the time of such telephonic notice, Tenant shall have the option but
not the obligation to perform such repairs to the Building necessary or
advisable to get its switch facility in operation at Tenant's sole cost and
expense. If such repairs by Tenant are repairs that would have had to be made by
Landlord pursuant to its repair obligations, Landlord shall reimburse Tenant for
the reasonable cost of such repairs, but only to the extent Landlord would have
incurred such expense(s) to complete such repairs.

     A total destruction of the Building in which the Premises are located shall
automatically terminate this Lease.

     20.  Eminent Domain.  If the Premises, or so much thereof as to render the
          --------------
balance unusable for the Permitted Use, shall be taken under power of eminent
domain, this Lease shall automatically terminate as of the later of the date of
such condemnation, or the date possession is taken by the condemning authority,
or as otherwise herein provided.  In the event of a partial taking, Tenant, at
its sole discretion, may elect to continue its occupancy in the remaining
portion of the Premises and Base Rent will be proportionately adjusted.
Landlord will retain any award which may be made in such taking or condemnation
as such relates to the Building including, but not limited to, all fee,
leasehold and easement estates in the land upon which the Building and the
Premises is located.  Tenant will receive any and all awards as such relate to
Tenant's loss of business, Tenant's furniture, fixtures and equipment, Tenant's
improvements to the Premises, and other items as such related to Tenant.  In the
event of a partial taking which does not result in a termination of this Lease,
Base Rent shall be proportionately adjusted.  Landlord may without any
obligation or liability to Tenant stipulate with any condemning authority for a
judgment of condemnation, and the date of taking under this clause shall then be
deemed the date agreed to under the terms of said stipulation.

     21.  Default.  The occurrence of any of the following shall constitute an
          -------
event of Default:

          (a)  The vacation, abandonment or desertion of the Premises by Tenant,
     except that if Tenant vacates but continues to pay Rent for the Premises
     through the remainder of the Term, said vacation will not be considered an
     event of Default.

          (b)  A failure by Tenant to have made any payment of Base Rent or
     Adjusted Base Rent by the tenth day following receipt of written notice by
     Tenant from Landlord of such failure to have made such payment of Base Rent
     or Adjusted Base Rent; provided,

                                       19
<PAGE>

     however, that Landlord shall not be obligated to give Tenant written notice
     of such failure more than twice in any calendar year.

          (c)  A failure by Tenant to observe or perform any provision of this
     Lease for fifteen (15) days after notice thereof from Landlord; provided
     that if such Default cannot reasonably be cured within such period, and
     Tenant promptly commences to cure such Default and thereafter diligently
     prosecutes the same to completion, Tenant shall not be deemed in Default.

          (d)  The making by Tenant of any general assignment for the benefit of
     creditors, or the attachment, execution or other judicial seizure of
     substantially all of Tenant's assets located at the Premises or of
     Tenant's interest in this Lease.

     If an event of Default shall occur, Landlord may, at any time:

               (i)  re-enter the Premises and take possession thereof and,
          subject to the provisions of the Landlord's Waiver and the provisions
          of Section 10 of the Lease, of all property of Tenant therein and
          remove Tenant and all other parties from the Premises without
          terminating this Lease, and at any time relet the Premises, or any
          part thereof, upon such conditions and at such rental as Landlord
          deems proper. In such event Landlord may receive and collect the rent
          from such reletting and apply it against any amounts due from Tenant
          hereunder, (plus expenses Landlord incurs in recovering possession of
          the Premises, placing the same in good condition, preparing the same
          for reletting, and all other related expenses, commissions and
          charges). Rent or other charges collected from a tenant to whom the
          Premises have been relet shall be applied to reduce any indebtedness
          due hereunder. Landlord shall not be deemed to have terminated this
          Lease or the liability of Tenant for the total liability hereunder by
          re-entry or any other act unless Landlord shall have specifically
          notified Tenant of Landlord's election to terminate this Lease.

               (ii) give written notice to Tenant of Landlord's election to
          terminate this Lease. In such event Landlord may recover from Tenant
          all damages related to Tenant's Default, including reasonable
          attorneys' fees, and in lieu of the damages that may be recoverable
          under subparagraph (i) above, Landlord shall be entitled to liquidated
          damages in an amount equal to the Rent reserved hereunder for the
          period which otherwise would have constituted the balance of the Term,
          discounted at the rate of the weekly average yield of U.S. Treasury
          Securities having a maturity date nearest to the expiration of the
          Term (including any exercised renewal term) as published in the
          Federal Reserve Statistical Release H.15 (519) or its successor, less
          the amount of the rental loss for the unexpired period of the Lease
          that could have been reasonably avoided by Landlord.

     22.  Rules and Regulations.  Tenant shall comply with the Rules and
          ---------------------
Regulations attached hereto, and such other rules and regulations as Landlord
may adopt from time to time.  Landlord shall not be liable to Tenant for the
breach of any lease by any other tenant in the

                                       20
<PAGE>

Building. Notwithstanding anything contained in this Paragraph 22, in the event
there is a conflict between the provisions of the Lease (and all Riders or
Exhibits thereto) and the Rules and Regulations, the provisions of the Lease
will prevail.

     23.  Requirements of Law.  Tenant shall, at its sole cost and expense,
          -------------------
promptly comply with all laws, orders, regulations and requirements of all
public authorities and any fire underwriters insurance rating agency or similar
organization which may impose any violation, order or duty upon Landlord or
Tenant with respect to the Premises, or with respect to the Building if arising
out of Tenant's use of the Premises.  Tenant  shall pay all costs, expenses,
fines, penalties or damages which may be imposed upon Landlord by reason of
Tenant's failure to comply with the provisions of  this paragraph.
Notwithstanding anything contained in this Paragraph 23, Tenant will not be
responsible or liable for violations that are not as a result of Tenant or
Tenant's use.  Any expenses incurred by Landlord related to any legal
requirements enacted after the Commencement Date that are capital expenses shall
be amortized as an Operating Expense as provided by Paragraph 1(p)(iv).

     24.  Surrender of Premises.  At the termination of this Lease Tenant shall
          ---------------------
surrender the Premises (and all keys thereto) to Landlord in good condition,
reasonable wear and tear excepted. Tenant shall remove its trade fixtures,
personal property and signs within ten (10) days after termination, Landlord
shall have the right to remove and store said property, at Tenant's expense,
without further notice to or demand upon Tenant. Tenant shall be responsible for
any and all charges and expenses incurred by Landlord for any damages that
result from the removal of such trade fixtures, personal property and signs.

     28.  Insurance.
          ---------

          (a)  Liability Insurance Carried by Tenant. Tenant shall obtain and
               -------------------------------------
     keep in force during the Term Commercial General Liability insurance
     protecting Tenant and Landlord (as an additional insured) against claims
     for bodily injury, personal injury and property damage based upon,
     involving or arising out of the use, occupancy or maintenance of the
     Premises and all areas appurtenant thereto. Such insurance shall be on an
     occurrence basis providing single limit coverage in an amount not less than
     $1,000,000 per occurrence with an "Additional Insured-Managers or Landlords
     of Premises" Endorsement and shall contain an amendment to the Pollution
     Exclusion to cover damage caused by heat, smoke or fumes from a hostile
     fire. The limits of said insurance shall not serve to limit the liability
     of Tenant or relieve Tenant of any obligation hereunder. All insurance to
     be carried by Tenant shall be primary and not contributory with any similar
     insurance carried by Landlord, whose insurance shall be considered excess
     insurance only.

          (b)  Liability Insurance Carried by Landlord. Landlord shall maintain
               ---------------------------------------
     property insurance covering the Building and Commercial General Liability
     Insurance in limits and with coverage generally deemed acceptable within
     the real estate industry. Landlord's insurance coverage shall be excess
     over Tenant's coverage required hereunder and Tenant shall not be named as
     an additional insured therein.

          (c)  Tenant's Property Insurance. Tenant shall maintain insurance
               ---------------------------
     coverage on all of Tenant's personal property, and Tenant alterations in
     the Premises. Such insurance shall be full replacement cost coverage with a
     deductible not to exceed $25,000 per occurrence. The proceeds from such
     insurance shall be used by Tenant for the replacement of personal property
     or the restoration of Tenant alterations. Tenant shall provide Landlord
     with written evidence that such insurance is in force.

          (d)  Insurance Policies.  Insurance required hereunder shall be with
               ------------------
     companies licensed to transact business in the state where the Premises are
     located, and maintaining during the policy term an "A.M. Best Rating" of at
     least A-VII as set forth in the most current issue of "Best's Insurance
     Guide." Tenant shall not permit anything which could invalidate the
     insurance policies referred to herein. Tenant shall deliver to Landlord
     certificates evidencing the existence and amounts of insurance required
     hereunder, listing the insureds and loss payable clauses required by this
     Lease. Such policy shall be cancelable or subject to modification only
     after thirty (30) days written notice to Landlord. At least ten (10) days
     prior to the expiration of such policies, Tenant shall furnish Landlord
     evidence of renewal thereof. In the event Tenant fails to do so, Landlord
     may order such insurance and charge the cost thereof to Tenant as Rent.

     29.  Waiver of Subrogation. Without affecting any other rights or remedies,
          ---------------------
Tenant and Landlord each hereby release and relieve each other, and waive their
right to recover damages against the other, for loss of or damage to the other
party's property arising out of or incident to the perils required to be insured
against under Paragraph 28. The effect of such release and waivers of

                                       22
<PAGE>

the right to recover damages shall not be limited by the amount of insurance
carried or required, or by any deductibles applicable thereto.

     30.  Waiver.  No waiver by Landlord of any provision of this Lease or
          ------
Landlord's consent to any act shall render unnecessary the obtaining of
Landlord's consent to or waiver of any subsequent act of Tenant or provision of
this Lease.  No agreement to accept a surrender of the Premises shall be valid
unless in writing and signed by two (2) officers of Landlord.

     31.  Unavoidable Delays.  If Landlord or Tenant (other than as to Tenant's
          ------------------
obligation to pay Rent) shall fail to timely perform any of its obligations as a
result of any labor disputes, inability to obtain labor or materials, acts of
God, governmental restrictions, regulations or controls, enemy or hostile
government action, civil commotion, fire or other casualty, or any other
condition beyond the reasonable control of the party obligated to perform, then
such failure shall not be deemed a breach of this Lease to the extent of and for
the time occasioned by such event. Lack of funds and inability to procure
financing shall not be deemed to be an event beyond the reasonable control of
Tenant.  As a condition precedent to Tenant claiming or relying upon an
unavoidable delay, Tenant shall give ten (10) days written notice to Landlord of
such event.

     32.  Subordination.  This Lease is, unless Landlord shall otherwise elect,
          -------------

encumbrances now affecting the fee title to the Building and to all ground and
underlying leases and mortgages or financings (including leasehold mortgages or
financings) which have been placed against or affect the real property of which
the Premises forms a part, and subject and subordinate all covenants,
restrictions, easements, encumbrances and to all ground and underlying leases
and mortgages and financings (including leasehold mortgages or financings) which
may hereafter affect title to the Building and  to the real property of which
the Premises forms a part provided that in the case of any encumbrance placed
against the Building or the real property of which the Premises form a part from
and after the date of this lease, this Lease shall only be subordinate if
Landlord provides Tenant with a signed and acknowledged Landlord's Waiver in the
form of Exhibit "B" hereto and a Subordination, Non-Disturbance and Attornment
Agreement in the form of Exhibit "C" hereto.  The term "mortgages" as used
herein shall include trust indentures and deeds of trust.  No further instrument
shall be necessary unless required by any such ground or underlying lessor or
mortgagee.  Should any ground or underlying lessor or mortgagee lease and/or
mortgage the real property of which the Premises forms a part, or any part
thereof, or should Landlord or any  ground or underlying lessor or mortgagee for
any other reason desire confirmation of such subordination, Tenant shall execute
and deliver, without charge, all documents (in form acceptable to such ground or
underlying lessor or mortgagee) subordinating this Lease and Tenant's rights
hereunder within ten (10) days of Landlord's written request therefor.

     33.  Notice to Mortgagee.  Tenant shall not exercise any right to terminate
          -------------------
this Lease by reason of constructive or actual eviction, or in the event of any
act or omission by Landlord which would give Tenant the right to terminate this
Lease, until (i) Tenant shall have given written notice of such act or omission
to the holder of any first mortgage to which this Lease is subject and
subordinate (provided the name and address of such holder shall previously have
been furnished to Tenant) and (ii) a reasonable period of time for remedying
such act or omission shall have elapsed

                                       23
<PAGE>

following the giving of such notice, during which Landlord and/or the holder of
such mortgage, or their agents or employees, shall be entitled to enter the
Premises and remedy such act or omission. During the period between the giving
of such notice and the remedying of such act or omission, Rent shall be abated
and apportioned to the extent that any part of the Premises shall be
untenantable.

     34.  Attornment.  In the event of a sale, transfer, or assignment of
          ----------
Landlord's interest in the Building or any part thereof, or in the event of any
proceedings brought for the foreclosure of, or in the event of the exercise of
any power of sale under any mortgage covering the Building or any part thereof,
or in the event of a cancellation or termination of any ground or underlying
lease covering the Building or any part thereof, Tenant will attorn to and
recognize such transferee, purchaser, ground or underlying lessor or mortgagee
as Landlord, so long as such terminating party recognizes and upholds this
Lease.

     or specifying such defaults, if any.

     be represented by Landlord, (ii) that there are no uncured defaults in
     Landlord's performance, and (iii) that not more than one month's rental has

where the Building is located.

     37.  Transfer of Landlord's Interest.  In the event of any transfer of

month-to-month tenancy, terminable by either party at the end of the month
following at least thirty (30) days' written notice, and shall be subject to all
the terms and conditions of this Lease (so far as same are applicable to a

                                       24
<PAGE>

     40.  Accord and Satisfaction. Payment by Tenant or receipt by Landlord of a

Landlord, be deemed to be on account of the earliest stipulated Rent then due.

payment shall be deemed an accord and satisfaction; Landlord may accept such
check or payment without prejudice to Landlord's right to recover the balance of
such Rent or to pursue any other remedy in this Lease or at law.

          ---------------
possession of the Premises, for recovery of Rent, or because of the breach of

other tenants. Tenant will be responsible for any costs in connection therewith.
Tenant shall maintain such signs in good condition and repair. Other than such
permitted signs (subject to Landlord's reasonable approval), Tenant shall not
place or install or suffer to be placed or installed or maintain any sign upon
or outside the Premises or the Building. In the event Landlord determines that

     Tenant agrees to execute an Amendment and Supplement of Lease in form and
     substance reasonably acceptable to Landlord confirming the exercise of the
     within option to expand, redefining the newly defined Premises, the
     redefining the newly defined Premises, the Base Rent and construction
     allowance.  Tenant may, subject to the terms and conditions of this Lease
     and Landlord's prior approval, (a) install an additional generator or
     increase the size and wattage of the original generator at Tenant's sole
     cost and expense, (b) increase the HVAC capacity for the Premises at
     Tenant's sole cost and expense, (c) install additional antennas at Tenant's
     sole cost and expense, and (d) upgrade the Building electrical system
     installed by Landlord to accommodate Tenant's electrical usage in the
     Option Space at Tenant's sole cost and expense.  Landlord shall provide the
     space for an additional transformer outside the Building to be installed by
     Tenant as a part of the Option Space's Base Rent.  The location(s) of all
     such improvements shall be approved by Landlord in Landlord's sole
     discretion.

          (b)  One Time Right of First Refusal.  If at any time during the Term
               -------------------------------
     (including the period covered by the Option set forth in the preceding
     paragraph) Landlord receives a bona fide offer from a third party to lease
     Building space containing all or a part of the Option Space, which Landlord
     intends to accept, Tenant shall have a right of first refusal to lease the
     same space as that covered in the third party's offer, upon terms which are
     equal to those offered by the third party for its entire space.  Tenant
     shall exercise said right of first refusal by giving Landlord written
     notice thereof within three (3) days from the date that Tenant receives
     written notice from Landlord stating the terms of such offer.  In the event
     Tenant elects to lease such space pursuant to its right of first refusal,
     Tenant shall execute an Amendment and Supplement modifying this Lease in
     form and substance satisfactory to Landlord, setting forth the Base Rent
     payable for said space along with such other terms and conditions as the
     parties may reasonably negotiate.  If Tenant does not choose to match a
     third party's offer and that third party takes occupancy of all or any part
     of the Option Space, Tenant's right of first refusal shall be deemed
     extinguished as to all of the Option Space.  Landlord shall not improve the
     economic terms under which such third party agrees to lease all or any part
     of the Option Space by more than 5% without first resubmitting such offer
     to Tenant as provided in this Paragraph 58(b). Nothing herein shall
     preclude Landlord from renewing or extending the tenancy of said third
     party.

     60.  Extension Option.
          ----------------

          (a)  Tenant shall have the option, exercisable by giving written
     notice (each, a "Renewal Notice") to Landlord not less than nine (9) months
     nor more than fifteen (15) months prior to the expiration of the original
     Term of this Lease or the renewal term, to renew and extend this Lease for
     two (2) consecutive five-year renewal terms, on the same terms as this
     Lease except that the Base Rent shall be equal to the prevailing Market
     Rate (as defined below). Tenant's exercise of any renewal option shall
     become irrevocable, subject to the parties' agreement on the Market Rate
     for such renewal term, upon Landlord's receipt of the Renewal Notice.

          (b)  Within ten (10) business days of Landlord's receipt of the
     Renewal Notice, Landlord shall deliver to Tenant its determination of the
     Market Rate; and if Tenant agrees with Landlord's determination, Tenant
     shall execute an Amendment and Supplement to Lease in form and substance
     satisfactory to Landlord and Tenant, confirming the extension of this Lease
     and setting forth the Base Rent payable during such Renewal Period along
     with such other terms and conditions as Landlord may reasonably require. If
     Tenant disagrees, Landlord and Tenant shall meet and confer at a mutually
     agreeable time and place within thirty (30) days after Landlord's receipt
     of Tenant's disagreement in order to reach an agreement concerning the
     Market Rate for the Premises for the applicable renewal term. If within
     sixty (60) days after receipt of the Renewal Notice, Landlord and Tenant
     are unable to agree on what Market Rate should be for the renewal term, the
     Market Rate for such renewal term shall be determined by the appraisal
     procedure described in subparagraph (c) below.

          (c)  In the absence of an agreement between Landlord and Tenant on the
     Market Rate for any renewal term during the time period specified in
     subparagraph (b) above, within ninety (90) days after Landlord's receipt of
     the Renewal Notice, Landlord and Tenant shall have each appointed an
     appraiser to determine the Market Rate for such renewal term by giving
     written notice to the other party of the name, address and telephone number
     of their respective appraisers. Each appraiser must (i) be a commercial
     leasing broker for Class "B" office buildings in the Denver area business
     district, (ii) have at least ten years experience in commercial leasing
     brokerage in the Denver area, and (iii) not be affiliated with Landlord or
     Tenant. The appraisers shall make their determination as to the Market Rate
     for the renewal term within thirty (30) days after their appointment. If
     the Market Rate determinations of the two appraisers vary from each other
     by no more than 5%, the Market Rate for the renewal term shall be the
     average of the two determinations. If the Market Rate determinations of the
     two appraisers vary by more than 5%, the appraisers shall promptly select a
     third appraiser who meets the qualifications set forth above. Such third
     appraiser shall make its determination as to the Market Rate, and the
     Market Rate for the renewal term shall be the average of the two appraisals
     which are closest to each other. Landlord and Tenant shall share the cost
     of the third appraiser, but shall each bear their own costs in connection
     with the two appraisers they select. Landlord and Tenant agree to be bound
     by the Market Rate as determined in accordance with the appraisal procedure
     set forth herein.

                                       32
<PAGE>

          (d)  The Market Rate for any renewal term determined by Landlord and
     Tenant pursuant to subparagraph (b) above or by the appraisers selected
     pursuant to subparagraph (c) above shall be based upon the following
     criteria:

          (i)  There shall be taken into consideration the comparative rents of
               known lease agreements consummated within twelve (12) months
               prior to the applicable Renewal Notice for similar space in Class
               "B" office buildings in the northern metropolitan Denver,
               Colorado area along the Interstate 25 and Interstate 36
               corridors; and

          (ii) In determining the Market Rate for the Premises for the
               applicable renewal term, there shall be taken into account the
               comparative rents described in subparagraph (i) above, provided
               that appropriate adjustments shall be made by taking into account
               (1) differences in length of lease terms, (2) the location of the
               Building, (3) the floor level at which the Premises is located,
               (4) the age, quality and amenities of the Building, (5) tenant
               improvement allowances and free rent concessions given, and (6)
               current operating expenses and impositions for the Building.

     The option provided for herein shall be exercisable by Tenant and Tenant's
permitted assignee only and may not be assigned or transferred by operation of
law or otherwise except to a permitted assignee as part of the assignment of
this Lease.  Tenant may exercise said option on the condition that it is not in
default under the Lease beyond any applicable cure periods, and that Tenant has
not subleased or assigned all or part of the Premises.

     be adjusted to conform to the actual measurements of the Premises;

          (b)  Base Rent [paragraph 1(i)]: The figures set forth thereat shall
     be adjusted substituting therefor the number obtained by multiplying the
     number of rentable square feet actually contained in the Premises as
     determined aforesaid by the applicable Rental Rate set forth at Paragraph
     1(i) of the Lease:

          (c)  Tenant's Share [paragraph 1(1)]: The percentage of Tenant's Share

an amendment and supplement to the Lease in form and substance satisfactory to
Landlord.

     Exhibit "F."  Such equipment will be located on a suitable structural curb
     or other roof supports (such roof supports to be provided by Landlord)
     placed directly over the vertical structural column supports in the main
     building structure.  The type of cooling equipment will be determined by
     Tenant and approved by Landlord in Landlord's sole discretion.  Tenant will

     two 4-inch double-walled supply and return pipes from the generator to the
     fuel tanks. Tenant shall have the right to install required fuel fill lines
     and ventilation lines in locations as reasonably determined by Tenant and

     Landlord and Tenant and in compliance with all laws. Tenant hereby agrees
     to protect, defend, indemnify and hold harmless Landlord for the use of the

     Building, in location(s) approved by Landlord in Landlord's sole
     discretion, by trenching in areas as required, including the parking lots,

     will have the right to connect its required conduit into the building and
     the Premises through penetrations in the exterior of the Building at
     locations to be determined by Landlord and Tenant.  Landlord agrees to

     Landlord shall upgrade the Buildings' power systems to accommodate such
     power needs by installing two additional 1500-amp transformers on or before
     February 20, 2000, subject, however, to delays caused by Public Service
     Company, the electric utility provider for the Building.  Landlord shall
     provide 400 amp service to the Premises from the date Tenant is permitted
     to enter the Premises until the date Public Service Company completes
     installation of such transformers.  Tenant will be permitted to run its
     electrical lines from the south end of the Building to Tenant's power room
     in conduit in a location mutually agreed upon by Landlord and Tenant.

          (f)  Conduit/Access/Riser Space.

               (i)  Tenant is permitted to install up to four chases which are

          approval shall not be unreasonably withheld, Tenant may install one 4-
          inch conduit to each of the telecommunications companies in the
          Building for Tenant's exclusive use at Tenant's sole cost and expense
          and in location(s) approved by Landlord in Landlord's sole discretion.
          Any conduit installed by Tenant shall become the property of Landlord
          and shall be surrendered with the Premises upon the expiration of the
          Lease and any extensions thereto.

                                       36

               (iii) Tenant will have the non-exclusive right to provide
          telecommunication services to other tenants in the building.  In the

     Tenant shall also have the right to modify any sprinkler systems within the
     Premises to a dry pipe pre-action system, provided that such modification
     complies with all laws and does not reduce the functionality of said
     sprinkler system within the Premises or anywhere in the Building.  Landlord
     shall cooperate with such reasonable modification and the cost of any such
     modification shall be paid for by Tenant.  Tenant shall have the right to
     relocate any wetlines in or about the Premises with Landlord's approval as
     to location, which approval shall not be unreasonably withheld or delayed,
     at Tenant's sole cost.

          (h)  Access to Loading Dock.  Subject to the rights of other tenants

     at all reasonable  times the loading areas at no additional cost to Tenant
     and to have reasonable access to the Premises from such loading areas.

          (i)  Staging Area during Construction. Tenant shall have the right to
     have access to and utilize at all reasonable times an area adjacent to the

     during the term of this Lease, as Rent, an amount equal to Tenant's
     proportionate share of the gas bill for the East Anchor Building.  Tenant's
     proportionate share of such gas bill shall be computed by multiplying the
     monthly gas bill for the East Anchor Building by a fraction, the numerator
     of which is the square footage of the Premises excluding the switch area
     and the denominator of which shall be 131,707 (the total rentable square
     footage of the East Anchor Building).

          (k)  Security System.  Tenant will have the option to install a
     security system for the Premises along with card reader entry devices and
     other cypher-type locking entry devices, as determined by Tenant.

     THIS SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT (hereinafter
referred to as "Agreement") made this ___ day of _______________, _______, among
                ---------
______________________________, a ____________________ (hereinafter referred to

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

          A.  Landlord and Tenant have entered into a certain lease dated
              -----------------------------------------------------------
          __________________, amended ________________________________, assigned
          ----------------------------------------------------------------------
          _______________________, (as amended and/or assigned, the "Lease")
          ------------------------------------------------------------------
          relating to the premises described in Exhibit A attached hereto and by
          -----------------------------------------------
          this reference made a part hereof (hereinafter referred to as the
          "Premises"); and
           --------

          B.  Lender has made or has committed to make a loan to Landlord in the
          approximate principal amount of $_________________ (hereinafter
          referred to as the "Loan") secured by a mortgage or deed of trust (as
                              ----
          the same may be amended, restated, extended, or otherwise modified
          from time to time, the "Mortgage") and an assignment of leases and
                                  --------
          rents (as the same may be amended, restated, extended, or otherwise
          modified from time to time, the "Assignment of Leases") from Landlord
                                           --------------------
          to Lender covering certain property described therein (the "Property")
                                                                      --------
          including the Premises; and

          C.  Tenant has agreed that the Lease shall be subject and subordinate
          to the Mortgage held by Lender, provided Tenant is assured of
          continued occupancy of the Premises under the terms of the Lease;

     NOW, THEREFORE, for and in consideration of the mutual covenants herein
contained, the sum of Ten Dollars ($10.00) and other good and valuable
considerations, the receipt and sufficiency of which are hereby acknowledged,
and notwithstanding anything in the Lease to the contrary, it is hereby agreed
as follows:
<PAGE>

               1.  Subordination and Consent.  Lender, Tenant and Landlord do
                   -------------------------
               hereby covenant and agree that the Lease with all rights,
               options, liens and charges created thereby (including, without
               limitation, any option or rights contained in the Lease, or
               otherwise existing, to acquire any or all of the Premises, or any
               superior leasehold interest therein), is and shall continue to be
               subject and subordinate in all respects to the Mortgage and to
               any renewals, modifications, consolidations, replacements and
               extensions thereof and to all advancements made thereunder.
               Tenant acknowledges that Landlord will execute and deliver to
               Lender an assignment of the Lease as security for said loan, and
               Tenant hereby expressly consents to such assignment.  Tenant
               agrees that if there is a default by Landlord in the performance
               and observance of any of the terms of such Loan, Lender may, at
               its option, demand all rents due under the Lease be paid by
               Tenant directly to Lender at the address specified below, or as
               otherwise specified by Lender.  Tenant agrees that upon Lender's
               written request for payment of rent directly to Lender, Tenant
               will timely remit any and all payments due under the Lease
               directly to, and payable to the order of, Lender.  Such payments
               to Lender will constitute performance of Tenant's payment
               obligations under the Lease.

               2.  Nondisturbance.  Lender does hereby agree with Tenant that,
                   --------------
               in the event Lender becomes the fee simple owner of the Property
               by foreclosure, conveyance in lieu of foreclosure or otherwise,
               so long as Tenant complies with and performs its obligations
               under the Lease, (a) the Lease shall continue in full force and
               effect as a direct Lease between the succeeding owner of the
               Property and Tenant, upon and subject to all of the terms,
               covenants and conditions of the Lease, for the balance of the
               term of the Lease, and Lender will not disturb the possession of
               Tenant, and (b) the Premises shall be subject to the Lease and
               Lender shall recognize Tenant as the tenant of the Premises for
               the remainder of the term of the Lease in accordance with the
               provisions thereof; provided, however, that Lender shall not be:

               a.   subject to any claims, offsets or defenses which Tenant
                    might have against any prior landlord (including Landlord);
                    or

               b.   liable for any act or omission of any prior landlord
                    (including Landlord);  or

               c.   bound by any rent or additional rent which Tenant might have
                    paid for more than the current month or any security deposit
                    or other prepaid charge paid to any prior landlord
                    (including Landlord); or

               d.   bound by any amendment or modification of the Lease made
                    without its written consent.
<PAGE>

               Nothing contained herein shall prevent Lender from naming Tenant
               in any foreclosure or other action or proceeding initiated by
               Lender pursuant to the Mortgage to the extent necessary under
               applicable Law in order for Lender to avail itself of and
               complete the foreclosure or other remedy.

               3.  Attornment.  Tenant does hereby agree with Lender that, in
                   ----------
               the event Lender becomes the owner of the Property by
               foreclosure, conveyance in lieu of foreclosure or otherwise, then
               Tenant shall attorn to and recognize Lender as the landlord under
               the Lease for the remainder of the term thereof, and Tenant shall
               perform and observe its obligations thereunder, subject only to
               the terms and conditions of the Lease.  Tenant further covenants
               and agrees to execute and deliver upon request of Lender an
               appropriate agreement of attornment to Lender and any subsequent
               titleholder of the Premises.

               4.  Lease Defaults.  In the event Landlord shall fail to perform
                   --------------
               or observe any of the terms, conditions or agreements in the
               Lease, Tenant shall give written notice thereof to Lender and
               Lender shall have the right (but not the obligation) to cure such
               default.  Tenant shall not take any action with respect to such
               default under the Lease, including without limitation any action
               in order to terminate, rescind or avoid the Lease or to withhold
               any rent or other monetary obligations thereunder, for a period
               of thirty (30) days following receipt of such written notice by
               Lender; provided, however, that in the case of any default which
               cannot with diligence be cured within said thirty (30) day
               period, if Lender shall proceed promptly to cure such default and
               thereafter prosecute the curing of such default with diligence
               and continuity, the time within which such default may be cured
               shall be extended for such period as may be necessary to complete
               the curing of such default with diligence and continuity.

               5.  Obligations and Liability of Lender.  Lender shall have no
                   -----------------------------------
               obligations nor incur any liability with respect to any
               warranties of any nature whatsoever, whether pursuant to the
               Lease or otherwise, including, without limitation, any warranties
               respecting use, compliance with zoning, hazardous wastes or
               environmental laws, Landlord's title, Landlord's authority,
               habitability, fitness for purpose or possession.  Furthermore, in
               the event that Lender shall acquire Landlord's interest in the
               Property, Lender shall have no obligation, nor incur any
               liability, beyond Lender's then equity interest, if any, in the
               Property, and Tenant shall look exclusively to such equity
               interest of Lender, if any, in the Property for the payment and
               discharge of any obligations or liability imposed upon Lender
               hereunder, under the Lease (or under any new lease with Tenant),
               and Lender is hereby released and relieved of any other
               obligations or
<PAGE>

               liability hereunder, under the Lease or under any such new lease.
               Lender shall not, either by virtue of the Mortgage, the
               Assignment of Leases or this Agreement, be or become a mortgagee
               in possession or be or become subject to any liability or
               obligation under the Lease or otherwise until Lender shall have
               acquired the Landlord's interest in the Property, by foreclosure
               or otherwise, and then such liability or obligation of Lender
               under the Lease (as modified by the terms of this Agreement)
               shall extend only to those liability or obligations accruing
               subsequent to the date that Lender has acquired Landlord's
               interest in the Property. Without limiting the generality of the
               foregoing, neither the Mortgage, the Assignment of Leases nor
               this Agreement shall, prior to Lender's acquisition of Landlord's
               interest in the Property, by foreclosure or otherwise, operate to
               place responsibility for the control, care, management or repair
               of the Property upon Lender or impose upon Lender responsibility
               for the carrying out of any of the terms or conditions of the
               Lease, and Lender shall not be responsible or liable for any
               waste committed on either the Premises or the Property by any
               party whatsoever, for any dangerous or defective condition of the
               Property or for any negligence in the management, upkeep, repair
               or control of either the Premises or the Property.

               6.  Severability.  If any portion or portions of this Agreement
                   ------------
               shall be held invalid or inoperative, then all of the remaining
               portions shall remain in full force and effect, and, so far as is
               reasonable and possible, effect shall be given to the intent
               manifested by the portion or portions held to be invalid or
               inoperative.

               7.  Governing Law.  This Agreement shall be governed by and
                   -------------
               construed in accordance with the laws of the State of Colorado.

               8.  Notices.  So long as the Mortgage remains outstanding and
                   -------
               unsatisfied, Tenant will mail or deliver to Lender, at the
               address and in the manner hereinbelow provided, a copy of all
               notices permitted or required to be given to the Landlord by
               Tenant under and pursuant to the terms and provisions of the
               Lease.  All notices or other communications required or permitted
               to be given pursuant to the provisions hereof shall be in writing

               addressee by first class United States mail, postage prepaid,
               registered or certified with return receipt requested, (ii) by
               delivering same in person to the addressee, or (iii) by delivery
               to a third party commercial delivery service for same day or next

               addressee, or (iii) upon delivery to such third party delivery
               service.  Notice given in any other manner shall be

     For good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereby agree as follows:

     1.   The Landlord agrees to send the Agent at an address designated by the
Agent a copy of any notice of default (or termination) (the "Default Notice") of

     3.   The Landlord consents to the granting of a security interest in all of

Commercial Code.  The Landlord agrees that all of the Personal Property, whether
or not affixed to or located or installed on the Premises, constitutes and shall

to the Premises or any other real estate.

     4.   The Landlord agrees that any and all liens, claims, demands, rights or
interests that the Landlord may now or hereafter have in or to the Personal
Property shall be and are hereby made subordinate and inferior to any now
existing or hereafter arising lien or security interest in favor of the Agent.

     5.   The Landlord agrees that if the Tenant defaults on its obligations to
the Agent and, as a result, the Agent undertakes to enforce its security
interest in the Personal Property, as follows:
<PAGE>

          (a)  the Landlord will cooperate with the Agent in its efforts to
assemble all of the Personal Property located on the Premises, provided,
however, that the Landlord shall not be obligated to incur any expense or other
obligation in connection with such cooperation;

          (b)  the Landlord will permit the Agent to remain on the Premises for
up to sixty (60) days after the Agent declares the default, provided that the
Agent, for the period of time the Agent uses the Premises, (i) pays or causes to
be paid the base rent or adjusted base rent or, in the case where the Lease has
terminated, the base rent or adjusted base rent that would have become due under
the Lease for such period if the Lease had not been terminated, for the period
of time the Agent uses the Premises; (ii) provides and retains the liability and
property insurance coverage and pays utilities required, or which would have
been required if the Lease had not been terminated under the Lease; and (iii)
delivers a written agreement to do so;

          (c)  the Agent or its representatives may enter upon the Premises at
reasonable times, and after written notice to the Landlord, for the purpose of
removing, or repossessing, the Personal Property, provided that the Agent
promptly repairs any and all physical damage to the Premises caused by such
removal;

          (d)  the Landlord shall not hinder the Agent's actions in enforcing
its liens on the Personal Property; and

          (e)  except as provided in subsection (b) of this Section 5, the Agent
may enter the Premises for such purposes without assuming the Lease and all
obligations and all obligations contained therein.

Upon any such removal, any liens, claims, demands, rights or interests of the
Landlord in the Personal Property shall be discharged and released.
Notwithstanding anything herein to the contrary, in no event shall the Agent's
right to enter or occupy the Premises pursuant to this Waiver extend beyond
sixty (60) days from the date of termination or expiration of the term of the
Lease, and at any time thereafter the Landlord shall have the right to have any
personal property of the Tenant that may be located upon the Premises removed
from the Premises in accordance with the terms of the Lease and applicable law.

     6.   This Waiver may be amended or modified only by an instrument in
writing signed by each of the parties hereto.

     7.   This Waiver may be executed in counterparts, each of which shall be
deemed an original but all of which taken together shall constitute one and the
same instrument.

     8.   This Waiver shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, administrators, successors and
assigns or encumbrances.

additional cost to complete the alterations and thereby agree to reimburse
Landlord for the amount by which the cost to complete the alterations (which
cost shall include an amount equal to five percent (5%) of Landlord's costs as
an administrative fee attributable to its construction coordination and
supervision) exceeds Landlord's costs without Tenant's changes, or (ii) agree to
reduce the scope of the alterations so that the actual cost of the alterations
does not exceed Landlord's costs without Tenant Changes.

If the Tenant is to provide any additional features, materials or work over and
above  that specified in this Work Letter, Tenant must receive the written
approval of Landlord, in advance, and must pay all costs and expenses for such
work.

Finally, Tenant understand and acknowledges that notwithstanding any
representation by Landlord or its agents to the contrary (i) Landlord estimates
that the time to complete construction described above is 2 to 4 weeks and that
Landlord will not commence construction until after the Lease is fully executed
by both parties; and (ii) if Tenant desires at its sole cost and expense, and
Landlord agrees, to make any changes in the scope of construction, then the
estimated completion of construction will be adjusted accordingly.  Any Tenant
delays in reviewing or approving space plans, construction documents, or
submittals, or in providing necessary information in the planning or
construction process will not postpone the Lease Commencement Date.

facilities and the parking areas of the Project with applicable Laws concerning
physical condition of, access to, or occupancy of such areas. So long as
Tenant's Improvements in the Premises are designed and constructed by Tenant in

compliance of the Premises with applicable law concerning access, physical
condition (including but not limited to asbestos removal and other environmental
matters), or occupancy not related to (i) Tenant's specific use of the Premises
or (ii) Tenant's Improvements or any alterations made by Tenant.

     4.4  Environmental Matters.
          ---------------------

          (a)  Hazardous Materials. Tenant shall not cause, or permit or allow
any of Tenant's employees, agents, customers, visitors, invitees, licensees,
contractors, assignees or subtenants (collectively, "Tenant's Parties") to cause
or permit any Hazardous Materials to be brought upon, stored, manufactured,
generated, blended, handled, recycled, treated, disposed or used on, under or
about the Premises, the Building, the common facilities, or the Project, except
for routine office and janitorial supplies in usual and customary quantities
stored, used, and disposed of in accordance with all applicable Environmental
Laws. As used herein, "Hazardous Materials" means any chemical, substance,
material, controlled substance, object, condition, waste, living organism or
combination thereof which is or may be hazardous to human health or safety or to
the environment due to its radioactivity, ignitability, corrosivity, reactivity,
explosivity, toxicity, carcinogenicity, mutagenicity, phytotoxicity,
infectiousness or other harmful or potentially harmful properties or effects,
including, without limitation, petroleum and petroleum products, asbestos,
radon, polychlorinated biphenyls (PCBs) and all of those chemicals, substances,
materials, controlled substances, objects, conditions, wastes, living organisms
or combinations thereof which are now or become in the future listed, defined or
regulated in any manner by an Environmental Law based upon, directly, or
indirectly , such properties or effects. As used herein, "Environmental Laws"
means any and all federal, state or local environmental, health or safety-
related laws, regulations, standards, decisions of courts, ordinances, rules,
codes, orders, decrees, directives, guidelines, permits or permit conditions,
currently existing and as amended, enacted, issued or adopted in the future
which are or become applicable to Tenant, the Premises, the Building, the common
facilities or the Project. Tenant and Tenant's Parties shall comply with all
Environmental Laws and promptly notify Landlord of the violation of any
Environmental Law or presence of any Hazardous Materials, other than office and
janitorial supplies as permitted above, on the Premises.

                                       5
<PAGE>

          (b)  Environmental Audit. At any time and from time to time Landlord
may retain an environmental consultant or engineer to conduct an audit or
environmental assessment of the Premises and Tenant's compliance with applicable
laws, rules and regulations. Tenant shall extend its full cooperation with the
audit or investigation. If Tenant is found not to be substantially in compliance
with applicable law, the entire cost of the audit or assessment shall be paid by
Tenant to Landlord upon demand; otherwise the cost shall be borne by Landlord.

          (c)  Indemnification. Tenant shall indemnify, protect, defend (by
counsel acceptable to Landlord) and hold harmless Landlord and its partners,
directors, officers, employees, shareholders, lenders, agents, contractors and
each of their respective successors and assigns (individually and collectively,
"Indemnitees") from and against any and all claims judgments, causes of action,
damages, penalties, fines, taxes, costs, liabilities, losses and expense arising
at any time during or after the Term as a result (directly or indirectly) of or
in connection with (i) Tenant's or Tenant's Parties' breach of any prohibition
or provision of this Article, or (ii) the presence of Hazardous Materials on,
under or about the Premises or other property as a result (directly or
indirectly) of Tenant's or Tenant's Parties' activities, or failure to act, in
connection with the Premises. This indemnity shall include the cost of any
required or necessary repair, cleanup or detoxification, and the preparation and
implementation of any closure, monitoring or other required plans, whether such
action is required or necessary prior to or following the termination of this
Lease. Neither the written consent by Landlord to the presence of Hazardous
Materials on, under or about the Premises, nor the strict compliance by Tenant
with all Environmental Laws, shall excuse Tenant from Tenant's obligation of
indemnification pursuant hereto. Landlord shall indemnify, defend, and hold
harmless Tenant, its officers, directors, shareholders, employees, agents and
contractors and each of their respective successor and assigns from and against
any and all claims, liabilities, losses, judgments, causes of action, damages,
penalties, fines, taxes, costs, liabilities and expenses arising at any time
during or after the Term as a result of Landlord's use at any time of Hazardous
Materials in the Common Areas or activities of prior owners or tenants, unless
and to the extent caused by any breach of Tenant's obligations hereunder.
Landlord's and Tenant's obligations pursuant to the foregoing indemnity shall
survive the termination of this Lease.

assessed and billed separately from the real property of which the Premises form
a part.  In the event any or all of Tenant's trade fixtures, furnishings,
equipment and other personal property shall be assessed and taxed with the real
property, Tenant shall pay to Landlord Tenant's share of the taxes within ten
days after delivery to Tenant by Landlord of a statement in writing setting
forth the amount of the taxes applicable thereto.

<PAGE>

     5.2  Rental Taxes. Tenant shall, simultaneously with the payment of any
          ------------
sums required to be paid under this Lease as rent, additional rent or otherwise,
reimburse Landlord for any sales, use, rental, transaction privilege or other
excise tax imposed or levied on, or measured by, the amount paid.  In the event
any tax, surcharge or regulatory fee is imposed by any governmental authority
upon or with respect to parking, parking fees paid or received, parking spaces
or vehicles parking in the parking spaces in the common facilities, Tenant shall
pay the same as additional rent hereunder with the monthly installments of Base
Rent or as otherwise required from time to time by Landlord.  The reimbursement
required hereunder is not intended in any event to allow or require
reimbursement of Landlord's income taxes or franchise taxes.

ARTICLE 6. PARKING AND COMMON USE AREAS

     6.1  Common Facilities. All parking areas, access roads, driveways,
          -----------------
pedestrian sidewalks and ramps, landscaped areas, drainage facilities, exterior
lighting, signs, courtyards, corridors, elevators (if any), entryways, public
restrooms, and other areas and improvements (all of which are referred to as
"common facilities") provided by Landlord for the general use in common of
tenants, their officers, agents, employees, customers and other invitees shall
at all times be subject to the exclusive control and management of Landlord, and
Landlord shall have the right from time to time to modify, enlarge or eliminate
the same and to establish, modify and enforce reasonable rules and regulations
with respect thereto.  Tenant's right to use the Premises includes the non-
exclusive right to use the common facilities.

     6.2  Parking. Landlord shall provide, operate and maintain parking
          -------
accommodations in the Project, together with necessary access thereto.  Tenant
shall be entitled to use 5 parking spaces, unreserved, in common with all other
tenants of the Project, within the parking field delineated on Exhibit H.  In
addition, subject to availability, Tenant may have the right to use an
additional 25 unreserved parking spaces in common with other tenants, in an area
designated by Landlord, at a charge per space to be reasonably determined by
Landlord as the market rate for such spaces.  No storage of vehicles or parking
for more than twenty-four (24) hours shall be allowed without Landlord's prior
written consent, except that Tenant may park up to 5 service trucks or vans,
each not in excess of 20 feet long, overnight in the areas designated on Exhibit
H.  Tenant acknowledges and agrees that Landlord shall not be liable for damage,
loss or theft of property or injury to persons in, upon or about the parking
area from any cause whatsoever.  Landlord shall have the right to establish, and
from time to time change (including relocating reserved covered parking spaces),
alter and amend, and to enforce against all users of the parking area such
reasonable requirements and restrictions as Landlord deems necessary and
advisable for the proper operation and maintenance of the parking area.
Landlord shall have the right from time to time to designate an area or areas
within the common facilities for purposes of parking vehicles of Tenant's
employees (collectively, "Authorized Parkers"), and its agents, representatives
and invitees.  Tenant shall within fifteen days after the Commencement Date
deliver to Landlord the license plate numbers of its Authorized Parkers and
thereafter, within ten days after there are changes in the list of Authorized
Parkers.  Tenant hereby authorizes Landlord to tow from the Project, at Tenant's
expense, any vehicle parking in an unauthorized parking space belonging to an
Authorized Parker and/or to attach violation stickers or notices thereto.  Each
vehicle shall, at

                                       7
<PAGE>

Landlord's option to be exercised from time to time, bear a permanently affixed
and visible identification sticker or vehicle tag to be provided by Landlord.

ARTICLE 7. OPERATING COSTS, REAL PROPERTY TAXES AND UTILITIES

     7.1  Payment. Tenant shall pay Tenant's pro rata share of all of: (i) the
          -------
Building's operating cost and (ii) the Project's operating cost, but only to the
extent the annual aggregate of those two amounts exceeds the actual Project's
operating cost and Building operating cost for the calendar year 2000 (the
"Expense Stop").  The Building's operating cost consists of those costs and
expenses directly associated with managing, operating, maintaining and repairing
the office building (or associated group of buildings designated by Landlord)
containing the Premises, including all electrical, heating, ventilating, air
conditioning, plumbing and other building systems (but not the cost for the
supply and use of such utilities by tenants), and the roof, any skylights and
interior and exterior walls; service and maintenance contracts; fire sprinkler
monitoring charges; energy management costs; and a management fee of 10% of the
other Building operating costs.  The Project's operating cost consists of the
total cost and expense incurred in managing, operating, maintaining and
repairing the Project and its common facilities excluding costs categorized as
Building operating cost, but including, without limitation, real property taxes
and general and special assessments; wages, salaries and employee benefits of
persons performing services in connection with the Project; utilities; parking
lot sweeping, sealing, patching and restriping; public liability and property
damage insurance, fire and extended coverage insurance, and rent interruption
insurance; supplies, materials, tools, parts, and equipment; equipment rental
charges; bookkeeping, accounting, legal and other professional charges and
expenses; fees for permits and licenses; administrative expenses; taxes other
than real property taxes; service and maintenance contracts; signage;
landscaping; and a management fee of 10% of the other Project operating costs.
The cost of capital improvements incurred by Landlord to comply with the
Americans with Disabilities Act or other law shall be amortized over its useful
life and the amortization amount included in operating costs.  Neither the
Building's operating cost nor the Project's operating cost shall include the
replacement of or structural repairs to the roof or the exterior walls, repairs
to the extent covered by warranty or insurance proceeds, alterations within
leased premises of other tenants for their sole or principal benefit, legal or
professional fees incurred by Landlord incurred in negotiating or enforcing
leases of other tenants or incurred for purposes not benefiting all tenants of
the Project.  On the first day of each month Tenant shall pay a monthly advance
charge on account of Tenant's pro rata share of the Building's operating cost
and of the Project's operating cost in excess of the Expense Stop.  The amount
of the monthly charge shall be established by Landlord and may be adjusted from
time to time by Landlord to reflect the actual cost.  Within 120 days after the
end of each fiscal year as established for the Project by Landlord, Landlord
shall provide to Tenant a reasonably detailed summary of the actual operating
costs showing Tenant's actual share and the amount by which Tenant has overpaid
or underpaid.  Any overpayment shall be credited to Tenant's operating costs
account no later than the beginning of the next monthly period.  Any deficiency
shall be payable within ten days after receipt of the statement.  In the
alternative, Landlord may, at its option during all or part of the Term of the
Lease, bill Tenant for its pro rata share of operating cost in excess of the
Expense Stop, in arrears, based on actual costs as they are incurred, in which
case Tenant shall pay the invoice within ten days after receipt.

                                       8
<PAGE>

     7.2  Allocation. Landlord may allocate the Project's operating cost on the
          ----------
basis of floor area throughout the entire Project, in which case Tenant's pro
rata share shall be the proportion that the rentable area of the Premises bears
to the total rentable area of all rentable space in the Project, or Landlord may
first allocate portions of the Project's operating cost, in a manner selected by
Landlord in good faith in its reasonable discretion, among different buildings
or groups of buildings in the Project, in which case Tenant's pro rata share of
the Project's operating costs shall be the proportion that the rentable area of
the Premises bears to the total rentable area of the building or group of
buildings in which the Premises is located and to which the portion of the
operating costs of the Project has been allocated. In the latter case, Tenant
shall be liable only for its share of the Project's operating costs allocated to
the building or group of buildings that includes the Premises. Tenant's pro rata
share of the Building's operating costs shall be that proportion that the
rentable area of the Premises bears to the total rentable area of all rentable
area in the office building or associated group of buildings in which the
Premises are located. The operating cost for the fiscal year in which this Lease
commences or terminates shall be apportioned so that Tenant shall not be
responsible for costs that relate to periods prior to or subsequent to the Term
of this Lease except any period of holding over. Landlord and Tenant agree that
as of the date of this Lease Tenant's pro rata share is 5.26% (calculated on the
basis of 12,321 rentable square feet in the Premises and 233,821 rentable square
feet in the Project at the date of execution of this Lease).

     7.3  Gross-up. The Building's operating cost shall be adjusted to reflect
          --------
level of occupancy such that the cost of services provided to tenants, if any,
which are not provided to vacant space or are provided to vacant space to a
reduced degree, are distributed among those tenants enjoying the services.  The
adjustment shall be made based upon sound accounting principles to project costs
at a 95% occupancy level whenever the actual occupancy rate is less than 95%.
In no event shall the adjustment result in reimbursement to Landlord of an
amount in excess of actual costs incurred by Landlord.

ARTICLE 8. CONSTRUCTION

     8.1  Delivery. If delivery of possession of the Premises to Tenant is
          --------
delayed beyond the anticipated Commencement Date because of a delay in the
completion of Landlord's Work or because of a failure of an existing tenant to
surrender possession of the Premises to Landlord, then this Lease shall remain
in full force and effect, Landlord shall not be liable to Tenant for any damage
occasioned by the delay, and the Commencement Date shall be changed to the date
actual delivery of possession to Tenant is effected. Notwithstanding the
foregoing, if delivery of possession is delayed more than 60 days after the
anticipated Commencement Date as set forth in Section 1.1, Tenant, by written
notice to Landlord, may terminate this Lease prior to taking possession, and
upon such termination any Security Deposit shall be refunded and both Landlord
and Tenant shall be released of all further obligation hereunder.

     8.2  Condition. Landlord, at Landlord's sole cost and expense shall
          ---------
construct in a workmanlike manner and in accordance with all applicable Laws the
work ("Landlord's

<PAGE>

Improvements") described on Exhibit C. Landlord has no obligation to design or
construct improvements or to make alterations in the Premises except as
specifically set forth in Exhibit C. Any changes in Exhibit C shall be subject
to approval by both Landlord and Tenant. Any defects in the alterations or
additions constructed by Landlord in accordance with Exhibit C shall
automatically be waived unless specified in a written punchlist delivered to
Landlord within ten days after Tenant takes possession. Landlord shall promptly
correct all defects set forth in the punchlist.

     8.3  Tenant's Work. Landlord shall permit Tenant and Tenant's
          -------------
representatives and contractors to enter the Premises prior to the Commencement
Date in order that Tenant may do such work as may be required by Tenant make the
Premises ready for Tenant's use and occupancy (excluding Landlord's Work)
("Tenant's Work").  Such permission is conditioned upon Tenant and its agents,
contractors, employees and invitees not interfering with Landlord's work in the
Premises, if any, and shall be subject to all the terms of this Lease except
Tenant's obligation to pay Base Rent.  Tenant acknowledges and agrees that
Landlord shall not be liable in any way for any injury, loss or damage which may
occur to Tenant, its agents, contractors, employees or invitees or to Tenant's
work and installations made in the Premises, all of the same being at Tenant's
sole risk.  Landlord and Tenant agree to reasonably cooperate in accomplishing
Landlord's and Tenant's Work concurrently and will coordinate all Work so as to
minimize interference with one another.  All costs of construction of Tenant's
Work are to be borne by Tenant, including, without limitation, the costs of
moving curbs, driveways, landscaping, and sidewalks necessitated by the design
of Tenant's equipment yard.

     8.4  Alterations and Approval. Promptly after delivery of the Premises,
          ------------------------
Tenant shall commence construction of Tenant's Work, at Tenant's sole cost and
expense, by delivering to Landlord plans and specifications (the "Design Plans")
for such work, for Landlord's approval and consent, which shall not be
unreasonably withheld or delayed, except that Landlord reserves the right to
withhold consent in Landlord's sole discretion for Tenant's Work affecting the
structure, safety, efficiency or security of the Building in which the Premises
is located, the systems ("Systems") and equipment ("Equipment") which affect the
Premises and other space in the Building or Project, or the appearance of the
Premises from any common or public areas.  At the time Tenant submits the Design
Plans to Landlord, Tenant shall provide Landlord with notice of whether Tenant's
Work will involve or affect any Hazardous Materials, whether such materials are
customary and usual based on standard industry practices, and all other
reasonable details relating thereto.

     8.5  Approval Conditions. Landlord reserves the right to impose
          -------------------
requirements as a condition of such consent or otherwise in connection with
Tenant's Work, including requirements that Tenant: (i) submit for Landlord's
information the names, addresses and background information concerning all of
the major architects, engineers, contractors, subcontractors and suppliers
Tenant proposes to use, (ii) obtain and post permits, (iii) submit conditional
and final lien waivers in compliance with Arizona law for all architects,
engineers, contractors, subcontractors, and suppliers performing the Work or
Tenant Work, (iv) permit Landlord or its representatives, upon reasonable
notice, to inspect Tenant's Work or the Work at reasonable times, and (v) comply
with such other reasonable requirements as Landlord may

                                       10
<PAGE>

impose concerning the manner and times in which Tenant's Work shall be done.
Landlord reserves the right to designate and supervise as Landlord sees fit, the
architects, engineers, contractors, subcontractors, and suppliers who will
design and perform Tenant's Work and supply materials affecting the operation of
Building systems and equipment, floor slabs or other load-bearing structural
elements. If requested in writing by Landlord, Tenant shall provide Landlord
with a copy of the complete construction drawings for the build-out and
installation of the Premises.

     8.6  Performance of Tenant's Work. Tenant shall use Tenant's best efforts
          ----------------------------
not to unreasonably disrupt other tenants of the Building during the build-out
and installation of Tenant's Work.  Tenant's Work shall be performed: (i) in a
thoroughly first class, professional and workmanlike manner, (ii) only with
materials that are new, high quality, and free of material defects, (iii)
strictly in accordance with Design Plans approved by Landlord in advance in
writing, (iv) so as not to adversely affect the Systems and Equipment or the
structure of the Building or the Project, (v) diligently to completion and so as
to avoid any unreasonable disturbance, disruption or inconvenience to other
tenants and the operation of the Project, and (vi) in compliance with all laws,
the Code and other provisions of this Lease, and such other reasonable
requirements as Landlord may impose concerning the manner and times in which
such Tenant's Work shall be done.  Any floor, wall or ceiling coring work or
penetrations or use of noisy or heavy equipment which may unreasonably interfere
with the conduct of business by other tenants at the Project shall, at
Landlord's option, be performed at times other than Landlord's normal business
hours at Tenant's sole cost.  If Tenant fails to perform Tenant's Work as
required herein or the materials supplied fail to comply herewith or with the
specifications approved by Landlord, and Tenant fails to cure such failure
within five (5) business days after notice by Landlord (except notice shall not
be required in emergencies), Landlord shall have the right to stop Tenant's Work
until such failure is cured (which shall not be in limitation of Landlord's
other remedies).

     8.7  Liens. Tenant shall pay all costs for Tenant's Work when due. Tenant
          -----
shall keep the Project and Premises free from any mechanic's, materialmen's,
architect's, engineer's or similar liens or encumbrances, and any claims
therefor, in connection with any of Tenant's Work.  Tenant shall remove any
claim, lien, or encumbrance of record relating to, caused by or resulting from
Tenant's Work, by bond or otherwise within fifteen (15) days after notice by
Landlord.  If Tenant fails to do so, Landlord may pay the amount (or any portion
thereof) or take such other action as Landlord deems necessary to remove such
claim, lien, or encumbrance, without being responsible for investigating the
validity thereof.  The amount so paid and costs incurred by Landlord shall be
deemed additional rent under this Lease payable within 30 days after demand,
without limitation as to other remedies available to Landlord.  Nothing
contained in this Lease shall authorize Tenant to do any act which shall subject
Landlord's title to, or any lender's interest in, the Project or Premises to any
such claims, liens, or encumbrances, whether claimed pursuant to statute or
other law or express or implied contract.

     8.8  Additional Installations. Tenant shall have the right, subject to the
          ------------------------
provisions of this Article 8 except section 8.3, and with prior written notice
to Landlord and Landlord's written permission, which shall not be unreasonably
withheld, to install, operate, maintain,

                                       11
<PAGE>

repair, and test the following equipment. Installation, operation, maintenance,
repair, and testing of the below equipment will be at Tenant's sole expense and
in compliance with all applicable laws. The equipment (with the exception of the
equipment described in subsection 8.8(d), which will be in locations to be
determined in the future) may be installed only in the locations set forth in
Exhibit I attached hereto. Installation of the equipment shall not be commenced
until Tenant has received Landlord's written approval of the location of each
piece of equipment and the screening of each piece of equipment from view, as
well as approval by any governmental planning or building authority with
jurisdiction over the Project ("Governmental Approval"). Tenant will submit all
documents and applications necessary to obtain the Governmental Approval within
2 weeks after the date this Lease is executed. If, despite diligent efforts,
Tenant is unable to obtain the Governmental Approval within 60 days after the
date of this Lease, Tenant may, upon 10 days' notice to Landlord, terminate this
Lease, in which case neither party shall have any further obligation hereunder.
If Tenant does not give notice to Landlord under this provision within 10 days
after expiration of the 60 day period, Tenant will be deemed to have waived the
foregoing right of termination.

               (a) Rooftop air conditioning and ventilation units and two
     refrigeration chilling towers and associated pipes, conduits, and ductwork
     outside the Premises in the Project.

               (b) Backup generator (1250 kw/480 volts), fuel tank, and
     associated electrical components outside the Premises in the Project. Until
     a permanent generator is installed, Tenant shall have the right to install
     and operate a temporary generator in an area adjacent to the Premises to
     protect Tenant's business from risks attendant to power failure in the
     Building.

               (c) One GPS antenna, one local 2 way antenna, and no more than 2
     satellite disks or dishes, each not more than 39" in diameter, on the roof
     of the Building.

               (d) Tenant may install two service vaults, on the side of the
     Building, by trenching in areas as required for such installation,
     including parking lots, sidewalks, curbing, and other common areas, so long
     as Tenant refills the trenches and replaces or repairs concrete or paving
     after completing the installation. Tenant will have the right to connect
     its conduit into the Building and the Premises through penetrations in the
     exterior of the Building in locations selected by Tenant (subject to
     Landlord approval). Landlord will allow Tenant underground and any other
     necessary access in, to, and about the Building to the public rights of way
     for installation of Tenant's telecommunications conduit to the Premises.
     Tenant may install conduit to construct Tenant's fiber optic system and
     Tenant may install two diverse paths for up to two four inch conduits from
     the Premises to two separate penetrations in the foundation of the Building
     and then to the property line, but in any instance where trenching is
     required outside the Premises Tenant will wherever reasonably feasible use
     a common trench with other tenants and occupants of the Project so as to
     minimize trenching in the Project, and Tenant will in good faith cooperate
     with Landlord and such other tenants or occupants in planning for and using
     a common trench.

     8.9  Provisions Concerning Installations on and Access to Roof.  The weight
          ---------------------------------------------------------
and size of any installations on the roof of the Building are subject to
Landlord's reasonable approval. All costs of installation and maintenance of
installations on the roof shall be borne by Tenant. Any such installation shall:

any roof warranty or maintenance contract; (ii) not result in any penetration of
the roof membrane; (iii) be consistent with structural support requirements, as

protect coverage or protection afforded by any roof warranty or maintenance

be released of all liability and responsibility for, and Tenant shall be solely
responsible for, all costs and expenses, including but not limited to, those

operation of the satellite dish or related equipment.

     9.4  Utilities.  All utility charges for the Premises shall be separately
          ---------
metered or submetered. Tenant shall pay directly to any public utility for any
utility which it uses in the Premises that is separately metered by such utility
and shall pay to Landlord, prior to delinquency, for any utilities supplied to
the Premises that are measured by a submeter, which is part of a Master Meter
for the Project, or portion thereof. The foregoing allocation shall not include
amounts attributable to special rates or factors not applicable to Tenant. With
any invoice for payment of Tenant's share of submetered utilities, Landlord

ARTICLE 10.  TENANT'S WORK, ALTERATIONS AND PERSONAL PROPERTY

     Tenant shall not commence Tenant's Work or any alterations, additions or
improvements to the Premises, including signs, without the prior written consent
of Landlord, which shall not be unreasonably conditioned, withheld, or delayed.
All such Tenant's Work, alterations, additions, or improvements shall be made or
done in accordance with plans and specifications approved by Landlord. Landlord
may, if in Landlord's reasonable judgment the circumstances require it,
condition its consent upon provision of a payment bond, in amount and form
reasonably satisfactory to Landlord, covering the work to be done by Tenant's
contractor. Any part of Tenant's Work, alterations, additions or improvements to
the Premises, including signs, but not including movable furniture, trade
fixtures, equipment, and co-located equipment and specifically excluding the
items described on Exhibit G hereto, shall, at Landlord's option, at the
termination or expiration of this Lease or of Tenant's right to possession,
become a part of the realty and belong to Landlord. Except as specifically set
forth in Article 8 above, Tenant shall not install any antenna, satellite dish
or other fixture or equipment on the roof or in the common facilities. In the
event Landlord consents to the making of any alterations, additions or
improvements to the Premises by Tenant, they shall be made by Tenant at Tenant's
sole cost and expense. Any contractor or person selected by Tenant to perform
work within the Premises must first be approved in writing by Landlord. Tenant
shall not permit any mechanic's or materialmen's lien to stand against the
Premises for any labor or materials provided to the Premises by any contractor
or other person hired or retained by Tenant. Tenant shall cause any such lien to
be discharged (by bonding or otherwise) within ten days after demand by
Landlord, and if it is not discharged within ten days, Landlord may pay or
otherwise discharge the lien and immediately recover all amounts (including
attorney's fees and costs) so expended from Tenant as additional rent. Tenant's
Work and all alterations and improvements shall be constructed of new materials,
in a good workmanlike manner, in accordance with applicable laws and codes,
including without limitation the Americans with Disabilities Act. Upon the
expiration or sooner termination of the Term of this Lease or of Tenant's right
to possession, Tenant shall, upon demand by Landlord, at Tenant's sole cost and
expense, forthwith remove any alterations, additions or improvements made by
Tenant, designated by Landlord to be removed, and Tenant shall, forthwith at its
sole cost and expense, repair any damage to the Premises caused by such removal
and restore the Premises to a condition reasonably comparable to their condition
at the commencement of the Lease (reasonable wear and tear excluded).

purchasers;

          (c) To enter the Premises either personally or by a designated

elected to exercise its renewal rights), for purposes of showing the Premises to
prospective tenants;

          (d) To grant to anyone the exclusive right to conduct any business or
render any service in or to the Project, provided such exclusive right shall not
operate to exclude Tenant from the use expressly permitted under Article 4;

          (e) To retain at all times and to use, subject to the foregoing
limitations, keys to all doors within and into the Premises. No locks shall be
changed without the prior written consent of Landlord except that Tenant may
install an encoded key card security and lock system so long as Tenant provides
Landlord with an entry key for use in accordance with Landlord's rights and
obligations under this Lease. This provision shall not apply to Tenant's safes,
or other areas maintained by Tenant for the safety and security of monies,
securities, negotiable instruments or like items; and

          (f) To restrict or prohibit vending or dispensing machines of any kind

the personal use of Tenant, its employees, licensees and agents and are not
visible from the common facilities.

ARTICLE 12.  DAMAGE TO PROPERTY; INJURY TO PERSONS; INSURANCE

     12.1  Tenant's Responsibility.  Tenant shall defend, indemnify and hold
           -----------------------
Landlord harmless from any and all claims arising from Tenant's use of the
Premises or the conduct of its business or from any activity, work, or thing
done, permitted or suffered by Tenant in or about the Premises, regardless of
fault or negligence which is imputed to Landlord as the owner of the Project but
which involves a condition of the Premises within the control of Tenant, its
employees or contractors. Tenant shall further defend, indemnify and hold
Landlord harmless from any and all claims arising from any breach or default in
the performance of this Lease by Tenant, or arising from any act or negligence
of Tenant, or of its agents or employees, and from all costs, attorneys' fees,
expenses and liabilities incurred as a result of any such claim. Tenant, as a
material part of the consideration to Landlord, hereby assumes all risk of
damage to property or injury to persons, in, upon, or about the Premises from
any cause, and Tenant hereby waives all claims in respect thereof against
Landlord, unless caused by active negligence of Landlord, its agents or
employees. Landlord shall not be liable for loss of or damage to any property by
theft or otherwise, or for any injury or

                                       15
<PAGE>

damage to persons or property resulting from fire, explosion, falling plaster,
steam, gas, electricity, water or rain which may leak from any part of any
building or from the pipes, appliances or plumbing works therein, or from the
roof, street or subsurface, or from any other place resulting from dampness or
any other cause whatsoever. Landlord shall not be liable for interference with
the natural light. Tenant shall give immediate notice to Landlord of any fire,
accident or defect discovered with the Premises or the Building. Tenant
acknowledges that it can protect itself against any or all of the foregoing
risks by procuring appropriate insurance.

     12.2  Tenant's Insurance.  Throughout the Term of this Lease Tenant shall
           ------------------
maintain ISO Special Form property insurance, including building and machinery
comprehensive form, in an amount equal to one hundred percent of the replacement
value of Tenant's trade fixtures, equipment, and other personal property located
on the Premises together with such other insurance as may be reasonably required
by Landlord's lender or by any government agency. All proceeds of Tenant's
policy of property insurance shall be payable to Tenant, and all proceeds of
policies of insurance procured by Landlord shall be payable to Landlord. Tenant
hereby waives any right to recovery from Landlord and Landlord hereby waives any
right of recovery from Tenant for any loss or damage (including consequential
loss) resulting from any of the perils insured against in the special form
property insurance policy with extended coverage endorsement. During the Term of
this Lease, Tenant shall, at Tenant's expense, maintain commercial general
liability insurance against claims for personal injury, death or property damage
occurring in, upon or about the Premises in an amount not less than $5,000,000
per occurrence and $5,000,000 annual aggregate (with a separate general
aggregate limit for the Premises), automobile liability insurance with a
combined single limit or equivalent in an amount not less than $2,000,000, and
workers' compensation insurance as provided by law. Tenant's policies of
liability insurance shall name Landlord as an additional insured, shall provide
coverage for blanket contractual liability, premises, products/completed
operations, and personal and advertising injury coverage. Tenant's policies of
insurance shall be primary and not contributory as to other insurance purchased
by or available to Landlord. A certificate of the insurance required to be
carried by Tenant under this Article 12 shall be delivered to Landlord prior to
the Commencement Date and thereafter at least thirty days prior to the
expiration of the then current policies. Upon the written request of Landlord,
copies of such policies shall also be delivered to Landlord. Each policy shall
contain an endorsement prohibiting cancellation or non-renewal without at least
thirty days prior notice to Landlord.

ARTICLE 13.  FIRE AND CASUALTY

     Except as hereafter provided, if the Premises are wholly or partially
destroyed or damaged by fire or other casualty, Landlord shall restore the
Premises with reasonable diligence; provided, however, that Landlord shall have
no obligation to restore improvements not originally provided by Landlord or to
replace any of Tenant's fixtures, furnishings, equipment or personal property.
Landlord need not commence repairs until insurance proceeds are available.
Proceeds of insurance payable with respect to a fire or other casualty shall be
received and held by Landlord. In the event the Premises are destroyed or
damaged by any fire or casualty not covered by the insurance maintained by
Landlord or to the extent of not less than twenty-five percent of the
replacement cost thereof, or if the fire or casualty

                                       16
<PAGE>

occurs within the last year of the Term of the Lease, then Landlord or Tenant
shall have the option to terminate this Lease by giving notice to the other
party within sixty days after the occurrence of such damage or destruction, in
which case Landlord shall retain all insurance proceeds with respect to the
Premises as its own property. If Landlord does not terminate this Lease as
provided above, this Lease shall continue in full force and effect, but Base
Rent shall be equitably abated as determined in Landlord's reasonable discretion
until the restoration is substantially complete. The provisions of this Lease
shall govern when this Lease shall be terminable as a result of a fire or
casualty, and no other rule or statute on the subject shall apply.
Notwithstanding anything in this Article 13, if, due to fire or other casualty,
Tenant is unable to use the Premises for conduct of Tenant's business and the
fire or casualty damage, in the parties' reasonable estimation, cannot be
repaired and the Premises restored to Tenant within 60 days after the date of
the casualty, Tenant may terminate this Lease by notice to Landlord within 30
days after the date of the casualty.

ARTICLE 14.  CONDEMNATION

     In the event any portion of the Premises shall be appropriated or taken
under the power of eminent domain which Tenant determines in its reasonable
judgment renders the Premises unusable by Tenant, either Landlord or Tenant
shall have the right to terminate this Lease, as of the date Tenant is required
to vacate a portion of the Premises, by giving notice in writing of such
election within thirty days after receipt by Tenant from Landlord of written
notice that Tenant's Premises have been or will be so appropriated or taken. If
neither Landlord nor Tenant elects to so terminate this Lease, or in the event
no portion of the Premises shall be appropriated under the power of eminent
domain by any public or quasi-public authority, then Landlord shall restore the
Premises to the extent practicable to their condition prior to the taking, and
thereafter the Base Rent shall be reduced on an equitable basis, taking into
account the relative value of the portion taken as compared to the portion
remaining. All awards or compensation for any taking of any part of the
Premises, whether payable to Landlord or Tenant, shall be the sole property of
Landlord. Notwithstanding anything to the contrary contained herein, Tenant
shall be entitled to receive any portion of an award of compensation relating to
damage to or loss of trade fixtures or other personal property belonging to
Tenant. Landlord shall be under no obligation to restore or replace Tenant's
furnishings, trade fixtures, equipment and personal property. For the purposes
of this Article 14, a voluntary sale or conveyance in lieu of condemnation shall
be deemed an appropriation or a taking under the power of eminent domain.

ARTICLE 15.  ASSIGNMENT AND SUBLETTING; SALE BY LANDLORD

     15.1  Transfer by Tenant.  Tenant shall not, either voluntarily or by
           ------------------
operation of law, assign, hypothecate or transfer this Lease, or sublet the
Premises or any part thereof, or permit the Premises or any part thereof to be
occupied by anyone other than Tenant or Tenant's employees, without Landlord's
prior written consent, which shall not be unreasonably withheld, provided the
proposed assignee or sublessee is reasonably satisfactory to Landlord as to
credit and character and will occupy the Premises for purposes not inconsistent
with Tenant's purposes as stated in Article 4. Landlord shall be under no
obligation to give or withhold consent until after all information reasonably
required by Landlord with respect to

                                       17
<PAGE>

the identity, background, experience and financial worth of the proposed
assignee, transferee, or subtenant has been provided to Landlord. In the event
Landlord fails to respond to Tenant's request to make an assignment or sublease
of its interest hereunder within thirty days after receipt of all the reasonably
requested information has been delivered to Landlord, it shall be deemed that
Landlord has not consented to the assignment or sublease. No hypothecation,
assignment, sublease or other transfer to which Landlord has consented shall be
effective for any purpose until such time as fully executed documents of such
transaction have been provided to Landlord, and, in the case of an assignment,
the assignee has attorned directly to Landlord, and in the case of a sublease,
the sublessee has acknowledged that the sublease is subject to all of the terms
and conditions of this Lease. Any assignment, mortgage, transfer or subletting
of this Lease which is not in compliance with the provisions of this Article 15
shall be voidable and shall, at the option of Landlord, terminate this Lease.
The consent by Landlord to an assignment or subletting shall not be construed as
relieving Tenant from obtaining the express written consent of Landlord to any
further assignment or subletting or as releasing Tenant from any liability or
obligation hereunder, whether or not then accrued. Except as provided in this
Article, this Lease shall be binding upon and inure to the benefit of the
successors and assigns of the parties.

     15.2  Splitting Profits.  In the event Landlord has approved an assignment
           -----------------
or sublease of this leases as hereinabove provided, then Tenant shall pay to
Landlord when and as received by Tenant one half of any consideration received
by Tenant on account of any assignment or sublease to which Landlord's consent
is required hereunder. Such payment to Landlord shall be equal to fifty percent
of any consideration received by Tenant in excess of the Base Rent and other
charges then payable by Tenant hereunder, after Tenant has recovered in full
Tenant's reasonable costs, fees and expenses incurred in connection with such
assignment or sublease, but limited to reasonable brokerage commissions,
reasonable costs of architectural and engineering fees, and leasehold
improvements required by the assignee or sublessee.

     15.3  Sale of Property.  In the event of a sale or conveyance by Landlord
           ----------------
of the Premises, Landlord shall be relieved of all future liability for the
covenants or conditions, express or implied, in favor of Tenant, and Tenant
shall look solely to Landlord's successor in interest. This Lease shall not be
affected by any sale, and Tenant shall attorn to the successor-in-interest. If
any Security Deposit has been made by Tenant, the successor-in-interest shall be
obligated to return it in accordance with the terms hereof and Landlord shall be
discharged from any further liability in reference thereto.

ARTICLE 16.  ESTOPPEL CERTIFICATE

     16.1  Certification.  Tenant shall at any time and from time to time upon
           -------------
not less than fifteen days' prior written notice from Landlord execute,
acknowledge and deliver to Landlord a statement in writing (i) certifying that
this Lease is unmodified and in full force and effect (or if modified, stating
the nature of such modification and certifying that this Lease, as so modified,
is in full force and effect) and the dates to which the rental and other charges
are paid in advance, if any; (ii) acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord hereunder, or specifying
such defaults if they are claimed; and (iii) certifying such other matters
relating to this Lease as Landlord may

                                       18
<PAGE>

reasonably request. Any such statement may be relied upon by any prospective
purchaser or encumbrancer of all or any portion of the real property of which
the Premises are a part.

     16.2  Failure to Provide.  Tenant's failure to deliver a statement within
           ------------------
the fifteen day time period prescribed above shall be conclusive upon Tenant (i)
that this Lease is in full force and effect, without modification except as may
be represented by Landlord, (ii) that there are no uncured defaults in
Landlord's performance, and (iii) that not more than one month's rental has been
paid in advance.

ARTICLE 17.  LANDLORD'S REMEDIES

     17.1  Events of Default.  The following shall constitute events of default:
           -----------------

           (a)  Tenant's failure to pay rent or any other amount due under this
     Lease within five days after receipt of a notice of nonpayment.

           (b)  Tenant's failure to execute, acknowledge and return an estoppel
     certificate which complies with the requirements of Article 16 or a
     subordination agreement which complies with the requirements of Article 19,
     within fifteen days after receipt of written request.

           (c)  Tenant's failure to perform any other obligation under this
     Lease within fifteen days after notice of nonperformance; provided,
     however, that if the breach is of such a nature that it cannot be cured
     within fifteen days after receipt of written request, Tenant shall be
     deemed to have cured if cure is commenced promptly (which, in no event
     shall be later than fifteen days following notice of nonperformance) and
     diligently pursued to completion; and provided further, that in the event
     of a breach involving an imminent threat to health or safety, Landlord may
     in its notice of breach reduce the period for cure to such shorter period
     as may be reasonable under the circumstances.

     17.2  Remedies.  Upon the occurrence of an event of default, Landlord, at
           --------
any time thereafter without further notice or demand, may exercise any one or
more of the following remedies concurrently or in succession:

          (a)  Terminate Tenant's right to possession of the Premises by legal
     process or otherwise, with or without terminating this Lease, and retake
     exclusive possession of the Premises.

          (b)  From time to time relet all or portions of the Premises, using
     reasonable efforts to mitigate Landlord's damages. In connection with any
     reletting, Landlord may relet for a period less than or extending beyond
     the Term of this Lease and may make alterations or improvements to the
     Premises without releasing Tenant of any liability. Upon a reletting of all
     or substantially all of the Premises, Landlord shall be entitled to recover
     all of its then prospective damages for the balance of the Term of the
     Lease measured by the difference between amounts payable under this Lease
     and the anticipated net proceeds of reletting. In no

                                       19
<PAGE>

     event shall Tenant be entitled to receive any amount representing the
     excess of avails of reletting over amounts payable hereunder.

          (c)  From time to time recover accrued and unpaid rent and damages
     arising from Tenant's breach of the Lease, regardless of whether the Lease
     has been terminated, together with applicable late charges and interest at
     the rate of 18% per annum or the highest lawful rate, whichever is less.

          (d)  Recover all reasonable attorneys' fees and other expenses
     incurred by Landlord in connection with enforcing this Lease, recovering
     possession and collecting amounts owed.

          (e)  Perform the obligation on Tenant's behalf and recover from
     Tenant, upon demand, the entire amount expended by Landlord plus 15% for
     handling, supervision, and overhead.

          (f)  Terminate this Lease for any breach and recover from Tenant all
     reasonable damages it may incur by reason of such breach, including the
     reasonable cost of recovering the Premises, and including the worth at the
     time of such termination of the excess, if any, of the amount of Base Rent
     and charges equivalent to rent reserved in this Lease for the remainder of
     the stated Term over the then reasonable rental value of the Premises for
     the remainder of the stated Term, all of which amounts shall be immediately
     due and payable from Tenant to Landlord.

          (g) Pursue any other remedies available at law or in equity.

     17.3  Subleases.  Upon a termination of Tenant's right to possession,
           ---------
whether or not this Lease is terminated, subtenancies and other rights of
persons claiming under or through Tenant: (i) shall be terminated or (ii)
Tenant's interest shall be assigned to Landlord, except that this provision
shall not affect or alter any rights of Tenant's asset based lender pursuant to
an executed and recorded Landlord Waiver. Landlord may separately elect
termination or assignment with respect to each such subtenancy or other matter.

ARTICLE 18.  NOTICES

     Notices required or permitted hereunder shall be given in writing,
personally delivered or sent by registered or certified mail, return receipt
requested, postage prepaid, or by a nationally recognized overnight courier
service (e.g., Federal Express, DHL) at the addresses set forth in Sections L
and M of the Basic Lease Provisions or at any other address designated by

          -------------
place liens and encumbrances on and against the Premises and the Project,
superior in lien and effect to this Lease and the estate created hereby, and
Tenant shall execute upon request subordination agreements to that effect;
provided however, that the subordination agreement shall provide that the holder
of the encumbrance will recognize Tenant's rights, notwithstanding any
foreclosure of the lien or encumbrance and also provided that any subordination
will not affect the rights of Tenant's asset based lender pursuant to a
previously executed and recorded Landlord Waiver.  Landlord shall obtain a non-
disturbance agreement in favor of Tenant from Landlord's lenders, in
substantially the lender's standard form, within 30 days after execution of this
Lease by Tenant.

owed under this Lease and performs and complies with the obligations and
conditions to be performed and complied with by Tenant under this Lease, Tenant
shall enjoy and have throughout the Term of the Lease the quiet and undisturbed
possession of the Premises.  Tenant acknowledges that Landlord may conduct a
remodeling of portions of the Project during the Term of this Lease, including
among other things the construction of upper level mall areas, the possible
enclosing of some of the mall areas, the demolition of certain buildings, the
construction of a new parking structure and other buildings, the realignment of
interior roadways and access routes to the Project.  Tenant agrees that provided
Tenant continues to have parking available in the Project, access to the Project
and Premises, and use of the Premises that such activities shall not be deemed a
breach of the foregoing covenant.

     19.3 Waiver of Landlord's Lien. Landlord hereby expressly waives any lien
          -------------------------
under ARS (S)(S)33-361 and 362, and any other liens Landlord may have under law
or otherwise, in any of Tenant's furniture, fixtures, equipment, or other
personal property located in the Premises including all items described on
Exhibit G.  Within 20 days after written request, Landlord will confirm its
waiver and use Landlord's best efforts to cause the owner of any superior
leasehold to Landlord or any secured lender to confirm its waiver in writing in
substantially Tenant's lender's standard form.  Simultaneously with the
execution of this Lease, Landlord shall execute, acknowledge for recording, and
deliver to Tenant, a Landlord Waiver in substantially the form attached hereto
as Exhibit J, which has been joined in recordable form by any ground or other
lessor with respect to the Premises, together with a nondisturbance agreement in
recordable form satisfactory to Tenant from any ground or other lessor.
Simultaneously with execution of this Lease, Landlord shall deliver a recordable
joinder to such Landlord Waiver and a recordable Non-Disturbance Agreement
executed by any lender holding a secured interest superior to that of Tenant in
the Premises.

ARTICLE 20. BROKERS

to the terms of a separate agreement between Landlord and

claiming shall indemnify and hold the other party harmless from and against any
such claim and all costs, expenses and liabilities incurred in connection with
such claim or any action or proceeding brought thereon, including but not
limited to attorneys' fees and court costs in defending such claim.

ARTICLE 21. RELOCATION {INTENTIONALLY OMITTED]

ARTICLE 22. SIGNAGE

     Landlord shall retain control over the exterior appearance of the Building
and the Premises as viewed from the public. Tenant shall not install or permit
to be installed any drapes, shutters, signs, lettering, decoration, advertising
or any items on the outside of the Premises or in the interior of the Premises
which are visible from the outside of the Premises and in any way adversely
alter the exterior appearance of the Building or the Premises. Notwithstanding
the foregoing, Tenant shall have the right at its sole cost and expense to
install signage on the south face of Building 3, provided Tenant obtains the
Landlord's prior written consent as to its size, color, design and location. All
letters or numerals on such signage shall be in accordance with the criteria
established by Landlord for the Project.

ARTICLE 23. GENERAL PROVISIONS

     23.1 Force Majeure. This Lease and the obligations of Tenant hereunder
          -------------

installations and improvements shall be at Licensee's cost, by contractors and
subcontractors approved in advance by Licensor, which approval shall not be
unreasonably withheld.  All of Licensee's Telecommunication Equipment placed by
Licensee within the Licensed Premises shall be at Licensee's sole risk and
expense.  All plans, diagrams, and specifications for initial and subsequent
improvements and installations of cable detailing the location and size of
Licensee's Telecommunications Equipment will be submitted to Licensor for prior
written approval, which approval will not be unreasonably withheld or unduly
delayed.  All of Licensee's Telecommunication Equipment will be installed in a
good and workmanlike manner using generally accepted construction standards by
properly licensed personnel.  Licensee shall install Licensee's
Telecommunication Equipment in a safe and proper manner so as to pose no hazard
to safety of life or property with respect to persons and property in or about
the Project.  No electrical grounding shall be permitted to other equipment in
the Raceways without Licensor's specific written approval of the method and
location of such grounding.  Prior to commencing any work on the Raceways,
Licensee shall obtain all necessary licenses, permits and consents and provide
copies of same to Licensor.  Licensor shall have the right to monitor all such
work, at its own expense.  All activities of Licensee initially associated with
the installation of Licensee's Telecommunication Equipment shall be performed in
such a way as to reasonably minimize interference with the operation of the
Project.  No monitoring or inspection of Licensee's work by Licensor shall be
deemed supervision of Licensee's employees, nor shall it be deemed to be a
representation or warranty of any particular level of telecommunications
expertise attained by Licensor or Licensor's representatives.  Licensee shall
monitor and supervise its own employees and shall assume responsibility for the
expertise and quality of its work, and shall not rely upon Licensor for same.
Licensee shall have in its employ a sufficient number of capable employees to
enable it to properly, adequately and safely perform hereunder.  Licensee shall
not disrupt, adversely affect or interfere with other providers of services in
the Project or buildings or with any tenant's use and enjoyment of the Licensed
Premises or the common areas of the Project.  Licensee shall take immediate
action to correct such interference after receiving notice thereof.

6.   Costs/Taxes.  Licensee shall be responsible for any and all cost, damage or
     -----------
expense arising from the installation, maintenance, operation or repair to the
Raceways or Licensee's Telecommunication Equipment, and any and all cost, damage
or expense to the Project or the property of Licensor or other licensees or
tenants of the Project arising from such installation, maintenance, operation or
repairs.  Licensee shall be responsible for the declaration and payment of any
applicable taxes or assessments against the Telecommunications Equipment owned
by Licensee located in the Project.

                                       36

7.   Compliance with Laws, Regulations and Project Rules.  The laws of the state
     ---------------------------------------------------
of Arizona without regard to conflict of law principles shall govern this
Agreement.  Licensee and Licensor agree to comply with all applicable laws,
ordinances, codes, rules and regulations of any governmental entity or agency
having jurisdiction with respect to the Project, including but not limited to,
Phoenix city codes, Arizona and federal statutes and regulations ("Applicable
Laws").  Licensee, its employees, contractors and agents will comply with the
rules and regulations of the Project.  Such rules are attached to the Lease,
which by this reference are incorporated herein.

8.   Protection of Equipment/Security.  Licensee acknowledges that interruptions
     --------------------------------
in utility services are not uncommon in facilities such as the Project and
Licensee acknowledges that any sensitive electronic equipment which may be used
in the Raceways or Premises will be protected by Licensee from utility service
interruptions through the use of backup power supplies, surge protectors and
other appropriate safety systems.  Licensee acknowledges that it has taken all
precautionary steps it deems necessary to protect such equipment, including the
acquisition of insurance if applicable.  Licensee agrees to indemnify and hold
Licensor harmless from any damages or losses (including indirect or
consequential damages and attorneys' fees) caused to any of Licensee's
telecommunications equipment by service interruptions.  This indemnity is in
addition to and not in substitution of any other indemnity in this license.
Licensor shall have no liability for theft or burglary, or for damage done by
unauthorized persons in the Raceways space unless caused by the gross negligence
or willful misconduct of Licensor, its agents, employees, or agents.  Licensor
shall not be required to insure against any such losses.  Licensee shall
cooperate fully in Licensor's efforts to maintain security in the Project.
Licensee agrees to surrender all keys, master entry cards or other means of
access in its possession upon the expiration or earlier termination of this
License.  Licensee shall pay Licensor for the cost of additional key(s) or
card(s) or for each replacement key(s) or card(s) for any key(s) or card(s).

9.   Warranty Against Damage and Interference. Licensee warrants that Licensee's
     ----------------------------------------
Telecommunications Equipment, and the installation, maintenance, operation and
repair thereof will not damage the Project or the buildings therein or interfere
with the use of such buildings or the operation of communications devices by
Licensee or by other lessees or licensees of Licensor.  If such damage or
interference does occur, Licensee shall take immediate action to correct same as
soon as Licensee becomes aware of such damage or interference, and in any event
within 24 hours after receipt of written notice from Licensor.  Licensor
reserves the right to disconnect power to any such Licensee's Telecommunications
Equipment which Licensee fails to correct after proper notification and cure
period.  Licensee agrees to be responsible for any damage caused to the Project,
building spaces, and/or any other property owned by Licensor or any tenant or
licensee of Licensor which may be caused by Licensee or any of its agents or
representatives.

10.  Relocation of Licensee's Telecommunication Equipment.  Licensor reserves
     ----------------------------------------------------
the right to require Licensee to relocate Licensee's Telecommunication Equipment
(other than the switch located within the Premises) to other areas within the
Project during the Term of this Agreement at Licensor's sole, reasonable
discretion.  Licensor shall reimburse Licensee for its reasonable expenses
incurred in connection with any such relocation.  If Licensor requests

                                       37
<PAGE>

such relocation, Licensor agrees to allow Licensee reasonable time to complete
the relocation, but not to exceed 30 days.

11.  Access by Licensee.  For the Term of this Agreement, Licensor shall provide
     ------------------
Licensee access to the buildings within the Project during Normal Business
Hours.  Upon prior notice, Licensee may have access after hours, but in that
event, Licensee shall compensate Licensor for reasonable trip charges and
overtime charges resulting from employees or agents of Licensor making trips to
the Project to provide after hours access.  Only authorized employees,
contractors, subcontractors, and agents of Licensee, other authorized regulatory
inspectors, or persons under their direct supervision and control will be
permitted to enter the Raceways.  Licensor may, at any time, require that
requests for access to the buildings in the Project be in writing on forms
provided by Licensor.

12.  Connections to Public Streets and Utilities.  Licensee acknowledges that
     -------------------------------------------
Licensor has no obligation to assure or guarantee Licensee the necessary
connections to public streets or utilities that may be necessary for the
operation of Licensee's Telecommunications Equipment in the Project.  It is
solely the responsibility of Licensee to negotiate agreements with public
utilities or third parties for these connections.  In the parking areas of the
Project, Licensor shall use commercially reasonable efforts to provide Licensee
access necessary for the operation of Licensee's Telecommunications Equipment,
provided the location thereof shall be subject to the prior written consent of
Landlord, which shall not be unreasonably withheld or delayed, and provided,
further that Licensee shall be required to return the area in which its
connections are located to the same condition existing prior to their
installation.

13.  Use of Electrical Services by Licensee.  Licensee shall pay for all costs
     --------------------------------------
of meters, submeters, wiring, risers, transformers, electrical panels, lighting,
air conditioning and other, if any, items required by Licensor which, in
Licensor's reasonable judgment are necessary to accommodate Licensee's design
loads and capacities, including, without limitation, the installation and
maintenance thereof.  Notwithstanding the foregoing, Licensor may withhold
consent for Licensee's installation of any wiring, risers, transformers,
electrical panels, lighting, or air conditioning if, in Licensor's reasonable
judgment, the same are not necessary or would cause damage or injury to the
buildings or cause or create a dangerous or hazardous condition or entail
excessive or unreasonable alterations or repairs to the buildings, or would
interfere with or create or constitute a disturbance to other tenants, licensees
or occupants of the Project.  Licensor shall use reasonable efforts to notify
Licensee in advance of any planned utility outages which may interfere with
Licensee's use, but in no event will Licensor be liable to Licensee for any
damages, direct or indirect, resulting from any loss of power.

14.  Licensee's Insurance.  No construction, alteration or removal operations
     --------------------
shall be initiated by Licensee unless Licensee has first obtained builders' risk
insurance in reasonable limits reasonably acceptable to Licensor.  In addition
to the builders' risk insurance required above, at all times Licensee shall
maintain in force at its expense, the required insurance as set forth in the
Lease.  If a waiver of subrogation clause is not contained in the form language
of the insurance policies, Licensee shall require that a waiver of subrogation
clause be added to its insurance policies.

                                       38
<PAGE>

15.  Hold Harmless.  Licensee shall indemnify Licensor and its respective
     -------------
subsidiaries and affiliates, directors, officers, agents, servants, employees
(the "Indemnified Parties") for and shall hold the Indemnified Parties harmless
from all fines, claims, demands, causes of action, liabilities, penalties,
judgments, orders, costs and expenses and suits (including costs and expenses of
defending against same and attorney, investigative and expert witness fee)
resulting from or asserted against the Indemnified Parties by reason of any
breach or non-performance of this Agreement by Licensee or Licensee's agents,
employees, or invitees, or any act or failure to act by Licensee hereunder.
This indemnity shall also cover injuries (and loss of life) or damages to any of
the Indemnified Parties, and damages to the Project; Licensor and Licensee shall
not be liable to the other or the other's agents or employees for any damage to
personal property resulting from any act, omission, or negligence of any other
tenant, Licensee or occupant of the Project.  The provisions of this paragraph
shall survive the termination of this Agreement.

16.  Casualty Damage.  If the Licensed Premises or any part thereof is damaged
     ---------------
by fire or other casualty, Licensee shall give prompt written notice thereof to
Licensor.  In case any of the buildings shall be damaged such that substantial
alteration or reconstruction of the shell, in Licensor's sole opinion, is
required (whether or not the Raceways or Licensee's Premises have been damaged
by such casualty) or in the event any mortgagee of Licensor's should require
that the insurance proceeds payable as a result of a casualty be applied to the
payment of the mortgage debt or in the event of any material uninsured loss to
the Project, Licensor may, at its option, terminate this Agreement by notifying
Licensee in writing of such termination within 60 days after the date of such
casualty.  If Licensor does not thus elect to terminate this Agreement Licensor
shall commence and proceed with reasonable diligence to restore the applicable
building shell, except that Licensor's obligation to restore shall not require
Licensor to spend for such work an amount in excess of the insurance proceeds
actually received by Licensor as a result of the casualty.  Licensor shall not
be liable for any inconvenience or annoyance to Licensee or injury to the
business of Licensee resulting in any way from such damage or the repair
thereof.  The provisions of this License shall govern when this License shall be
terminable as a result of fire or casualty and no other rule or statute on the
subject shall apply.

17.  Assignment, Subletting and Transfers.
     ------------------------------------

     a.   By Licensee.  Licensee shall not transfer (including transfers
          -----------
occurring by operation of law), convey, mortgage, pledge, hypothecate, or
encumber this Agreement or grant any license, concession, or other right to use
any portion of the Raceways or the Licensed Premises without the prior written
consent of Licensor, which shall not be unreasonably withheld, but shall be
conditioned upon a simultaneous assignment of the Lease to the same party
hereunder, and any such transfer or assignment shall not release Licensee from
its obligations under this Agreement. Any prohibited transfer is void and of no
effect.

     b.   By Licensor.  Licensor may transfer and assign its rights and
          -----------
obligations under this Agreement. Such transfer shall release Licensor from any
further obligations under this Agreement. If Licensor's interest in the Project
is conveyed or transferred, such conveyance

                                       39
<PAGE>

or transfer shall be deemed the assumption of the obligations of this License by
the grantee or transferee, at the sole option of the grantee or transferee.

18.  Removal of Licensee's Telecommunication Equipment and Restoration.  Except
     -----------------------------------------------------------------
with respect to the switch located in Licensor's Premises, the removal of which
shall be governed by Article 10 of the Lease, upon expiration or earlier
termination, Licensee shall at Licensor's election and at Licensee's sole
expense remove all of Licensee's Telecommunication Equipment from the Project
and restore the Licensed Premises and the Project to the condition in which it
existed prior to the installation of Licensee's Telecommunication Equipment
except for reasonable wear and tear, and damage caused by casualty.  If Licensor
so elects, Licensee's Telecommunications Equipment shall be removed within 30
days of expiration or termination.  If Licensee does not timely remove all of
Licensee's Telecommunications Equipment, Licensor may remove any or all of
Licensee's Equipment and Licensee agrees to pay to Licensor, on demand, the
reasonable cost thereof, plus a 15% administrative fee thereon.  If any of
Licensee's Telecommunications Equipment remains at the Project for more than 30
days after the expiration or earlier termination of the License, such Equipment
shall be deemed to be abandoned by Licensee and shall become the sole property
of Licensor, and Licensor shall not be required to pay Licensee any compensation
therefor.  Notwithstanding anything to the contrary in this Section 18, nothing
herein shall in any way impair Tenant's right to remove any item as described in
Article 10 or Exhibit G of the Lease, or the rights of Tenant's lender under the
Landlord Waiver described in Section 19.3 of the Lease, or any subsequent waiver
executed by Licensor.

19.  Default.
     -------

     a.   Definition of Default.  The occurrence of any of the following shall
          ---------------------
constitute a default by Licensee:  (1) failure to pay License Fees or any other
sum due by Licensee under this Agreement within 5 days after notice, (2) failure
to vacate on or before the last day of the Term of this Agreement; (3) if
Licensee is in default under the Lease beyond any applicable cure period
acquisition; or (4) failure to comply with any other provision of this Agreement
if such failure to comply is not cured as soon as reasonably possible but in no
event beyond 30 days after delivery of written notice by Licensor to Licensee.
However, Licensee shall not be in default under subclause (4) above if Licensee
promptly commences to cure such noncompliance and diligently proceeds in good
faith to cure same after receiving written notice of such default.

     b.   Remedies. If Licensee is in default as defined in subparagraph (a)
          --------
above beyond any applicable cure period, Licensor may (with or without demand
for performance) and with or without terminating this Agreement, terminate
Licensee's right of possession by giving five day's written notice to vacate or
by giving written notice terminating this Agreement. In addition, Licensor shall
have the right to any other remedy, whether in law or equity, Licensor may
recover actual damages incurred.

     c.   Attorneys' Fees, Interest, and Other Expenses. In any lawsuit
          ---------------------------------------------
enforcing rights hereunder, the prevailing party shall be entitled to recover
reasonable attorneys', investigative, and expert witness fees and costs from the
non-prevailing party, plus all out-of-pocket

                                       40
<PAGE>

expenses. All delinquent sums due by Licensor or Licensee shall bear interest at
the rate of 18% per annum from date of default until paid

20.  General Provisions.  Articles 1.3, 8.6, 8.7, 8.8, 18, 24.1, 24.3, 24.4,
     ------------------
24.6, 24.7, 24.8, 24.9 and 24.12 of the Lease are incorporated herein by
reference, provided the use in the Lease of the term Landlord shall apply to
Licensor, Tenant shall apply to Licensee, and Lease shall apply to this
Agreement.

                                LANDLORD WAIVER

     This LANDLORD WAIVER (the "Waiver") is entered into as of the _____ day of
January, 2000 by and among PARK CENTRAL MALL, L.L.C., an Arizona limited
liability Company (the "Landlord"), PAC-WEST TELECOMM, INC., a California
corporation (the "Tenant"), and UNION BANK OF CALIFORNIA, N.A., a national
banking association, in its capacity as administrative lender (the "Agent") for
itself and other financial institutions (collectively, the "Lenders").

                                   RECITALS

     A.   The Landlord and the Tenant have entered into that certain lease dated
as of _________________, 2000, (as such lease may have been amended to date, the
"Lease") covering the premises as defined and described in the Lease (the
"Premises"). The Premises are located on the real property described in Exhibit
"A" attached hereto and incorporated herein by this reference.

     B.   As partial security for Tenant's repayment and performance of its
obligations under certain credit facilities extended and to be extended in the
future to the Tenant by the Lenders, the Tenant has granted or will grant a
security interest in certain goods, inventory, and other personal property owned
by the Tenant, some of which may be located in the Premises, to the Agent.

     C.   In connection with the Tenant's granting of such security interest,
the Agent requires certain assurances from the Landlord.


                                   AGREEMENT

     For good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereby agree as follows:

                                       45
<PAGE>

     1.   The Landlord agrees to send the Agent at an address designated by the
Agent a copy of any notice of default (or termination) (the "Default Notice") of
the Lease at the same time that such notice is sent to Tenant and allow the
Agent the period of time equal to the grace period already permitted under the
Lease in order to cure any such default.  Until further written notice from the
Agent, the address of the Agent for all notices is as follows:

                    Union Bank of California, N.A.
                    1800 Harrison Street, Suite 1400
                    Post Office Box 1020
                    Oakland, California 94604-1020

                    Attention: Gail Fletcher
                               Vice President - Community Banking Group

     2.   The Landlord consents to the granting of a security interest in all of
the Personal Property of Tenant to be located on the Premises (the "Personal
Property"), including any part of the Personal Property that is now or is
hereafter installed or affixed to the Premises, or that is deemed to be
"fixtures" within the meaning of the then applicable Uniform Commercial Code. As
used herein, "Personal Property" means all of Tenants now owned or leased and
hereafter owned or leased telecommunications equipment, telecommunications
switches, antennas, computer hardware, cable, fibre optic cable and other fibre
optic transmission facilities, transmission equipment, machinery, equipment,
specially installed fire suppression or air conditioning system components,
furniture, furnishings, fixtures, and other tangible personal property,
including dies, tools, jigs and office equipment. "Personal Property" does not
include Landlord's pre-existing fire suppression or air conditioning equipment
located in the Premises. The Landlord agrees that all of the Personal Property,
whether or not affixed to or located or installed on the Premises in a manner
which would classify it as a "fixture," constitutes and shall remain Personal
Property and shall not be deemed a part of the real estate.

     3.   The Landlord agrees that any and all liens, claims, demands, rights or
interests that the Landlord may now or hereafter have in or to the Personal
Property shall be and are hereby made subordinate and inferior to any now
existing or hereafter arising lien or security interest in favor of the Agent.

     4.   If the Tenant defaults on its obligations to the Agent or the Lenders
and, as a result, the Agent undertakes to enforce its security interest in the
Personal Property or if the Landlord delivers a Default Notice, as provided in
Section 1 above; provided that Agent has notified Landlord in writing of
Tenant's default and Agent's undertaking to enforce its security interest,
Landlord agrees as follows:

               (a)  the Landlord will reasonably cooperate with the Agent in its
efforts to assemble all of the Personal Property located on the Premises,
provided, however, that the Landlord shall not be obligated to incur any expense
or other obligation in connection with such cooperation;

                                       46
<PAGE>

               (b)  the Landlord will permit the Agent to remain on the Premises
for up to sixty (60) days after the Agent declares the default, provided that
the Agent, for the period of time the Agent uses the Premises, (i) pays or
causes to be paid the rental payments and all rental adjustments (excluding
default triggered rental adjustments) with respect to such period or, in the
case where the Lease has terminated, the rental payments and all rental
adjustments (excluding default triggered rental adjustments) that would have
become due under the Lease for such period if the Lease had not been terminated,
for the period of time the Agent uses the Premises; (ii) provides and retains
the liability and property insurance coverage and pays all other amounts Tenant
is required to pay under the Lease, or which would have been required if the
Lease had not been terminated under the Lease; and (iii) delivers a written
agreement to do so;

               (c)  the Agent or its representatives may enter upon the Premises
at reasonable times, and after written notice to the Landlord, for the purpose
of removing, or repossessing, the Personal Property, provided that the Agent
promptly repairs any and all physical damage to the Premises and/or the building
in which the Premises are situated caused by such removal;

               (d)  the Agent may enter the Premises for such purposes without
assuming the Lease and all obligations and all obligations contained therein.

Upon any such removal, any liens, claims, demands, rights or interests of the
Landlord in the Personal Property shall be discharged and released.
Notwithstanding anything herein to the contrary, in no event shall the Agent's
right to enter or occupy the Premises pursuant to this Waiver extend beyond
sixty (60) days from the date of termination or expiration of the term of the
Lease, and at any time thereafter the Landlord shall have the right to have any
personal property of the Tenant that may be located upon the Premises removed
from the Premises in accordance with the terms of the Lease and applicable law.

     5.   This Waiver may be amended or modified only by an instrument in
writing signed by each of the parties hereto.

     6.   This Waiver may be executed in counterparts, each of which shall be
deemed an original but all of which taken together shall constitute one and the
same instrument.

     7.   This Waiver shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, administrators, successors and
assigns or encumbrancers.

     8.   The rights and obligations of the parties to this Waiver shall be
governed by the laws of the State of Arizona. Any legal actions with respect to
this Waiver shall be brought in either the state superior court in Maricopa
County, City of Phoenix, State of Arizona, or the federal district court which
serves the City of Phoenix.

     IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Waiver as of the date first above written.

                                    RIDER 1


     RIDER 1 to Office Lease dated _______________, 199__, (the "Lease") by and
between PARK CENTRAL MALL, L.L.C., an Arizona limited liability company
("Landlord"), and PAC-WEST TELECOMM, INC., a  California corporation ("Tenant").

     1.   Option to Extend.  Provided that Tenant is not in default of the Lease
          ----------------
beyond any applicable cure periods, and that no event shall have occurred or
state of facts exists which if continued uncured will, with the lapse of time or
the delivery of notice, or both, constitute an event of default, then Tenant
shall have, and is hereby granted, the option to extend the Initial Term for two
additional periods of five years (the "Renewal Term").  Except as set forth in
Section 2 of this Rider, Tenant's occupancy of the Premises during the Renewal
Term shall be governed by all of the terms, conditions, covenants and provisions
of the Lease to which this Rider is attached except that Tenant shall have no
further option to extend the Term after the expiration of the second Renewal
Term.  If Tenant desires to exercise its option to extend the Initial Term or
the first Renewal Term, it must give Landlord notice in writing ("Option
Notice") of its intent to do so at least one hundred eighty days, but no more
than three hundred sixty-five days, prior to the expiration of the Initial Term
or the first Renewal Term.

ANNUAL BASE RENT BASED ON FAIR MARKET RATE

     2.   Annual Base Rent During the Renewal Term.
          ----------------------------------------

          (a)  Landlord and Tenant shall have thirty days after Landlord
receives the Option Notice within which to agree on the Annual Base Rent for the
Renewal Term based upon the "then fair market rental value of the Premises" as
defined below. If the parties agree on the Base Rent for the Renewal Term within
thirty days, they shall amend this Lease by stating the Base Rent for the
Renewal Term and each subsequent year.

          (b)  If Landlord and Tenant are unable to agree on the Base Rent for
the first year of the Renewal Term within the thirty day period, then the Base
Rent shall be the "then fair market value of the Premises" as determined in
accordance with this Rider.

          (c)  The "then fair market rental value of the Premises" means what a
landlord under no compulsion to lease the Premises and a tenant under no
compulsion to lease the Premises, would determine as rent for the first year of
the Renewal Term, as of the commencement of the Renewal Term, taking into
consideration among other relevant matters, the use permitted under the Lease,
the quality, size, shape, design, and location of the Premises and the rental
rates for similar office buildings in the Phoenix metropolitan office market
area. Notwithstanding the foregoing, the then fair market rental value of the
Premises for the Renewal Term will not be less than the Base Rent payable during
the last year of the Initial Term.

                                       52
<PAGE>

          (d)  Within seven days after the expiration of the thirty day period
set forth above, Landlord and Tenant shall each appoint a real estate appraiser
with at least five full years full-time commercial appraisal experience in the
area in which the Premises are located to appraise the then fair market rental
value of the Premises. If either the Landlord or the Tenant does not appoint an
appraiser within ten days after the other has given notice of the name of its
appraiser, the single appraiser appointed shall be the sole appraiser and shall
set the then fair market rental value of the Premises. If two appraisers are
appointed pursuant to this paragraph, they shall meet promptly and attempt to
set the then fair market rental value of the Premises. If they are unable to
agree within the thirty days after the second appraiser has been appointed, they
shall attempt to elect a third appraiser meeting the qualifications stated in
this paragraph within ten days after the last day the two appraisers are given
to set the then fair market rental value of the Premises. If they are unable to
agree on the third appraiser, either the Landlord or Tenant may petition the
presiding civil court judge of the Maricopa County Superior Court for the
selection of a third appraiser who meets the qualifications stated in this
paragraph. Landlord and Tenant shall split equally the cost of appointing the
appraisers and of paying the appraiser's fees. Within thirty days after the
selection of the third appraiser, a majority of the appraisers shall set the
then fair market rental value of the Premises. If a majority of the appraisers
are unable to set the then fair market rental value of the Premises within
thirty days after selection of the third appraiser, the three appraisals shall
be averaged and the average shall be the then fair market rental value of the
Premises.

     3.   Definitions.  Capitalized terms used in this Rider without definition
          -----------
shall have the definition assigned to such terms in the Lease to which this
Rider is attached, unless the context requires otherwise.

     4.   Full Force and Effect.  Except as specifically modified by this Rider,
          ---------------------
the Lease to which this Rider is attached remains in full force and effect.
