                           RHYTHMS NETCONNECTIONS INC.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION:

THE COMPANY: RHYTHMS NetConnections Inc. (the "Company"), a Delaware 
corporation, was organized under the name Accelerated Connections Inc. 
effective February 27, 1997. The Company's name was changed to RHYTHMS 
NetConnections Inc. as of August 15, 1997. The Company is in the business of 
providing high-speed data communications services on an end-to-end basis to 
business customers and end users. The Company began service trials in the San 
Diego, California, market in December 1997 and began commercial operations in 
San Diego effective April 1, 1998.

The Company's ultimate success depends upon, among other factors, rapidly 
expanding the geographic coverage of its network services; entering into 
interconnection agreements with incumbent local exchange carriers, some of 
which are competitors or potential competitors of the Company; deploying 
network infrastructure; attracting and retaining customers; accurately 
assessing potential markets; continuing to develop and integrate its 
operational support system and other back office systems; obtaining any 
required governmental authorizations; responding to competitive developments; 
continuing to attract, retain, and motivate qualified personnel; and 
continuing to upgrade its technologies and commercialize its network services 
incorporating such technologies. There can be no assurance that the Company 
will be successful in addressing these matters and failure to do so could 
have a material adverse effect on the Company's business, prospects, 
operating results, and financial condition. As the Company continues the 
development of its business, it will seek additional sources of financing to 
fund its development. If unsuccessful in obtaining such financing, the 
Company will continue expansion of its operations on a reduced scale based on 
its existing capital resources.

INTERIM RESULTS (UNAUDITED): The accompanying consolidated financial 
statements should be read in conjunction with the Company's financial 
statements included in Amendment No. 3 to Form S-4 as filed with the 
Securities and Exchange Commission on October 19, 1998.

The accompanying consolidated financial statements (unaudited) have been 
prepared in accordance with generally accepted accounting principles for 
interim financial information and, therefore, do not include all the 
information and footnotes required by generally accepted accounting 
principles for complete financial statements. In the opinion of management, 
these statements have been prepared on the same basis as the audited 
financial statements and include all adjustments, consisting only of normal 
recurring accruals, that are necessary for the fair statement of results for 
the unaudited interim periods. The data disclosed in these notes to 
consolidated financial statements is also unaudited. The preparation of 
financial statements in conformity with generally accepted accounting 
principles requires management to make estimates and assumptions that affect 
the reported amounts of assets and liabilities and the disclosure of 
contingent assets and liabilities at the financial statement date, as well as 
the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates. The operating results for 
the interim period are not necessarily indicative of the results to be 
expected for a full fiscal year or for any future periods.

NOTE 2 - NET LOSS PER SHARE:

The Company has adopted Statement of Financial Accounting Standard ("SFAS") 
No. 128, "Earnings Per Share." Basic earnings per share ("EPS") is calculated 
by dividing the income or loss available to common stockholders by the 
weighted average number of common shares outstanding for the period, without 
consideration for common stock equivalents. Diluted EPS is computed by 
dividing the income or loss available to common stockholders by the weighted 
average number of common shares outstanding for the period in addition to the 
weighted average number of common stock equivalents outstanding for the 
period. For the interim periods ended September 30, 1998 and 1997, the 
diluted net loss per share computations excludes 41,771,084 and 12,280,000
shares, respectively, subject to conversion or repurchase by the Company, 
since the effect of these shares would be antidilutive.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED):

NOTE 3 - SUBSEQUENT EVENTS:

Effective October 21, 1998, the Company began an exchange offer of its 
$290,000,000 principal amount at maturity of 13.5 percent Senior Discount 
Notes that would allow for registration of such notes under the Securities 
Act of 1933, as amended. The exchange offer was completed November 20, 1998, 
at which time $289,000,000 of the notes had been exchanged for registered 
notes that have substantially the same terms and conditions as the 
unregistered notes, except that the registered notes are not subject to the 
restrictions on resale or transfer that apply to the unregistered notes.

Effective November 4, 1998, the Company completed a two-for-one split of its 
Common Stock. As a result of this stock split, the Company's number of 
authorized shares (including Common and Preferred) increased to 83,653,186. 
The accompanying consolidated financial statements have been restated for all 
periods presented to reflect the stock split.

                        FINANCIAL INFORMATION (CONTINUED)

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

The following discussion and analysis is based on the consolidated financial 
statements of Rhythms NetConnections Inc. (the "Company" or "Rhythms") and 
the notes thereto and should be read in conjunction with such consolidated 
financial statements and related notes thereto presented previously. Certain 
statements set forth below constitute "forward-looking statements." Such 
forward-looking statements involve known and unknown risks, uncertainties, 
and other factors that may cause the actual results, performance or 
achievements of the Company, or industry results to be materially different 
from any future results, performance, or achievements expressed or implied by 
such forward-looking statements. Given these uncertainties, investors and 
prospective investors are cautioned not to place undue reliance on such 
forward-looking statements. Factors that could cause or contribute to such 
differences include, but are not limited to, those discussed in the "Risk 
Factors" and "Business" sections contained in the Company's Amendment No. 3 
to Form S-4 as filed with the Securities and Exchange Commission on October 
19, 1998. The Company disclaims any obligation to update information 
contained in any forward-looking statement.

RESULTS OF OPERATIONS:

During the first nine months of fiscal year 1998, the Company continued the 
development of its business operations. Commercial service commenced April 1, 
1998 in the San Diego market and June 1, 1998 in San Francisco. The Company 
launched its East Bay and San Jose operations in July 1998 and its Los 
Angeles operations in September 1998. Build-outs and development of 
additional markets continued in accordance with the Company's initial rollout 
of 11 markets expected to be completed during the first half of 1999.

During the first quarter of 1998, the Company received $18,000,000 from the 
sale of its Series B Preferred Stock. During the second quarter, the Company 
issued 13.5 percent senior discount notes due 2008 in the principal amount at 
maturity of $290,000,000, combined with total warrants to purchase an 
aggregate 1,972,000 shares of Common Stock, for net proceeds to the Company 
of $143,962,000 (after issuance costs). Also during the second quarter, the 
Company entered into a 36-month lease line that provides for up to 
$24,500,000 in equipment.

THREE MONTHS ENDED SEPTEMBER 30, 1998

Revenues recorded during the third quarter reflect the continued penetration 
of the San Diego and San Francisco markets and initial sales in the East Bay, 
San Jose, and Los Angeles markets. Revenues comprise primarily DSL service 
and installation charges, net of discounts given to customers upon service 
establishment. Network service costs for the quarter also reflect the 
increases in commercial service and include customer installation costs, line 
and backbone expenses, the cost of customer premise equipment, equipment 
operating leases, and repair and support costs.

Selling, general, and administrative expenses for the quarter were $7,059,000 
and reflect a continued increase in staffing levels, increased marketing 
efforts coinciding with the launch of commercial services, and increased 
legal fees associated with development of additional markets.

Interest income of $2,160,000 for the quarter was generated from the 
Company's invested cash balances, which included the proceeds from the 
issuance of debt and warrants during the second quarter in the net amount of 
$143,962,000. The Company recorded $5,259,000 in amortized debt discount and 
costs during the quarter, a direct result of the debt issuance. The debt 
issuance discount of $139,635,000 is being amortized using the effective 
interest method through May 15, 2003. The value ascribed to warrants of 
$6,567,000 and debt issuance costs of approximately $6,403,000 are being 
amortized using the effective interest method over the period the notes are 
outstanding (ten years).

The Company continues to be in a net operating loss tax position through 
September 30, 1998; consequently, no provision for income taxes was recorded 
in the first through third quarters of 1998.

RESULTS OF OPERATIONS (CONTINUED):

NINE MONTHS ENDED SEPTEMBER 30, 1998

Revenues and network and service costs were insignificant during the first 
quarter of fiscal year 1998 as a result of alpha and beta customer tests, 
while second quarter revenues and network and service costs reflect 
penetration of the San Diego and San Francisco markets and third quarter 
revenues reflect operations in the additional markets of East Bay, San Jose, 
and Los Angeles, as discussed above in the third quarter results.

For the first nine months of 1998, selling, general, and administrative 
expenses of $14,041,000 reflect the continued increase in staffing levels, 
marketing efforts, and legal fees as discussed above in the third quarter 
results.

Interest income of $3,834,000 through September 30, 1998 was generated from 
the invested cash balances as discussed in the third quarter results above, 
with a majority of the income recorded in the third quarter. The Company 
recorded $8,446,000 in amortized debt discount and costs during the first 
nine months of 1998, a direct result of the debt issuance, as discussed above 
in the third quarter results.


CHANGES IN FINANCIAL POSITION:

Through December 31, 1997, the Company had issued $12,576,000 in Common and 
Series A Preferred Stock. During the first quarter of fiscal 1998, the 
Company received proceeds of $18,000,000 upon the issuance of Series B 
Preferred Stock and received $521,000 from other Common and Series A 
Preferred Stock issuances. On May 5, 1998, the Company received proceeds of 
$143,962,000 upon the issuance of 13.5 percent senior discount notes and 
associated warrants (see "Results of Operations" discussion above). 
Additionally, during the first nine months of 1998, the Company received 
$6,606,000 cash from a sale/leaseback agreement and borrowed a net $293,000 
on an existing financial institution loan.

As discussed above in "Results of Operations," the Company launched 
commercial services during 1998 and continued its market build-out and 
development efforts. The result on financial condition was increased 
operating losses, increased accounts payable and accrued expenses, increased 
collocation expenditures, and smaller increases in accounts receivable, 
inventory, and other assets.


LIQUIDITY AND CAPITAL RESOURCES:

As discussed above in "Results of Operations" and "Changes in Financial 
Position," through September 30, 1998 the Company had financed its operations 
primarily through the issuance of senior discount notes for net proceeds of 
$143,962,000, private placements of equity totaling $31,097,000, utilization 
of operating equipment leases totaling $26,500,000, and borrowings under a 
note payable from a financial institution of $1,000,000. As of September 30, 
1998, the Company had an accumulated deficit of $23,452,000, cash and cash 
equivalents of $20,236,000, and short-term investments of $133,703,000.

Through September 30, 1998, the net cash used in the Company's operating 
activities of $9,159,000 primarily related to selling, general, and 
administrative expenses. Cash used by the Company for collocation fees was 
$8,450,000. Net cash provided by financing activities, including the senior 
discount note issuance, was $169,363,000. The cash provided by financing 
activities also included $18,292,000 from the issuance of Preferred Stock in 
March 1998, and payment of $6,403,000 in debt issuance costs.

The 13.5 percent senior notes were issued at a discount; cash proceeds from 
the issuance were $150,365,000 and the Company incurred approximately 
$6,403,000 in debt issue costs for net proceeds of $143,962,000. The notes 
accrete in value through May 15, 2003 at a rate of 13.5 percent per annum, 
compounded semi-annually; no cash interest will be payable prior to that 
date. The debt issue costs are being amortized using the effective interest 
method over the period the notes are outstanding (ten years). Effective 
October 21, 1998, the warrants issued in connection with the notes are 
exercisable at a price of $0.01 per share. The warrants expire May 15, 2008. 
The warrants may be required to be repurchased by the Company for cash upon 
the occurrence of a Repurchase Event, as defined in the provisions of the 
warrant agreement entered into in connections with the debt issuance. The 
value ascribed to the warrants of $6,567,000 results in additional debt 
discount, which is being amortized using the effective interest method over 
the ten-year life of the notes.


                                       9

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED):

In November 1997, the Company entered into a 36-month master equipment lease 
with Sun Financial Group, Inc. ("SFG") to finance $2,000,000 of the Company's 
network equipment and network installation and deployment. The Company 
utilized the full $2,000,000 in leasing and, in May 1998, entered into 
another financing arrangement with SFG for up to $24,500,000 of additional 
lease financing. In connection with this additional financing, the Company 
issued 239,325 warrants to SFG to purchase Common Stock at a price of $4.45 
per share.

ACI Corp. and ACI Corp.-Virginia, the Company's wholly owned subsidiaries 
formed in 1998, operate as Competitive Local Exchange Carriers ("CLECs"). 
Both subsidiaries procure, construct, and operate network facilities and 
provide the underlying DSL connections for Rhythms services. A portion of the 
network equipment held under operating leases is for the benefit of ACI Corp. 
and ACI Corp.-Virginia as lessees, as applicable.

The Company believes that the net proceeds from the issuance of the senior 
discount notes, together with its existing cash, lease line proceeds, and 
future revenue generated from operations will be sufficient to fund the 
Company's operating losses, capital expenditures, lease payments, and working 
capital requirements for the next 24 months associated with the operation of 
its initial 11 markets. The Company intends to expand into 30 markets across 
the country by the end of year 2000; accordingly, it has signed 
interconnection agreements with five Independent Local Exchange Carriers and 
has obtained CLEC authority in 19 states. To facilitate the expansion, the 
Company expects its operating losses and capital expenditures to increase 
substantially. The Company expects that additional financing will be required 
following the initial 11 market rollout; this may include commercial bank 
borrowings, leasing, vendor financing, or the private or public sale of 
equity or debt securities. Actual capital requirements may vary based upon 
the timing and success of the Company's rollout. The Company's capital 
requirements may change as a result of regulatory, technological, and 
competitive developments or if (i) demand for the Company's services or its 
anticipated cash flow from operations is less or more than expected, (ii) the 
Company's development plans or projections change or prove to be inaccurate, 
(iii) the Company engages in any acquisitions, or (iv) the Company 
accelerates deployment of its network services or otherwise alters the 
schedule or targets of its rollout plan. Other than the lease financing, 
which is committed in full to certain equipment purchases, the Company has no 
present commitments or arrangements assuring it of any future equity or debt 
financing, and there can be no assurance that any such equity or debt 
financing will be available to the Company or available on favorable terms. 
In the event other additional financing alternatives are not completed, the 
Company believes that its existing cash resources are adequate to continue 
expansion of its operations on a reduced scale.


RISKS AND UNCERTAINTIES:

LIMITED OPERATING HISTORY; EARLY STAGE OF DEVELOPMENT

The Company was incorporated in February 1997, entered into its first 
interconnection agreement with an ILEC in July 1997, began to offer trial 
services in San Diego, California in December 1997 and began offering 
commercial services in San Diego on April 1, 1998. The Company has a limited 
operating history, has limited commercial operations and its primary 
activities to-date have consisted of the procurement of required governmental 
authorizations, the negotiation and execution of interconnection agreements 
with five ILECs, the identification of collocation space and locations for 
the Company's Connection Points, Metro Service Centers and business offices, 
the acquisition and deployment of equipment and facilities, the hiring of 
management and other personnel, the raising of capital and the development 
and integration of its operational support system ("OSS"), and other back 
office systems. As of September 30, 1998, the Company had insignificant 
revenues. As a result of its limited operating history, the Company does not 
have extensive historical financial data or operations upon which an 
evaluation of the Company or its prospects can be based. In addition, the 
Company's senior management team and other employees of the Company have 
worked on operations of the Company for less than one year.


                                       10
<PAGE>

RISKS AND UNCERTAINTIES (CONTINUED):

LIMITED OPERATING HISTORY; EARLY STAGE OF DEVELOPMENT (CONTINUED)

The Company's prospects must be considered in light of the risks, expenses, 
and difficulties encountered by new companies competing in rapidly evolving 
markets. To address these risks, the Company must, among other things, 
rapidly expand the geographic coverage of its network services; raise 
additional capital; enter into interconnection agreements with additional 
ILECs, some of which are competitors or potential competitors of the Company; 
deploy network infrastructure; attract and retain customers; continue to 
attract, retain, and motivate qualified personnel; accurately assess 
potential markets; continue to develop and integrate its OSS and other back 
office systems; obtain any required governmental authorizations; comply with 
evolving governmental regulatory requirements; increase awareness of the 
Company's services; respond to competitive developments; and continue to 
upgrade its technologies and commercialize its network services incorporating 
such technologies. There can be no assurance that the Company will be 
successful in addressing these and other risks, and failure to do so would 
have a material adverse effect on the Company's business, prospects, 
operating results, financial condition and its ability to make principal and 
interest payments on its indebtedness.

UNPROVEN BUSINESS STRATEGY; UNCERTAINTY OF MARKET ACCEPTANCE

The Company's business strategy is unproven and, to be successful, the 
Company must, among other things, develop and market network services that 
are widely accepted by businesses and its Channel Partners at prices that 
will yield a profit. The Company began to offer trial services in San Diego, 
California in December 1997 and began offering commercial services in San 
Diego on April 1, 1998. There can be no assurance that the Company's services 
offered in any geographic market will achieve commercial acceptance. The 
prices the Company charges for its services are in some cases higher than 
those charged for some competing services, and there can be no assurance that 
sufficient numbers of customers will be willing to pay the prices charged by 
the Company for its services. Accordingly, the Company cannot predict whether 
its prices will prove to be commercially acceptable, whether demand for the 
Company's services will materialize at the prices it desires to charge or 
whether current or future pricing levels will be sustainable. Because of the 
foregoing factors, among others, the Company cannot forecast its revenues or 
the rate at which it will add new customers with any degree of accuracy. 
There can be no assurance that the Company will ever achieve favorable 
operating results or profitability, or generate sufficient positive cash flow 
to service or repay its indebtedness. The failure to achieve or sustain 
desired pricing levels or to achieve or sustain broad market acceptance would 
result in a material adverse effect on the Company's business, prospects, 
operating results, financial condition, and its ability to make principal and 
interest payments on its indebtedness.

HISTORICAL LOSSES AND ANTICIPATED FUTURE LOSSES; FLUCTUATIONS IN OPERATING 
RESULTS

The Company has incurred net losses and experienced negative operating cash 
flow each month since its inception in February 1997. As of September 30, 
1998, the Company had an accumulated deficit of approximately $23.5 million. 
The Company currently intends to rapidly and substantially increase its 
capital expenditures and operating expenses in an effort to expand its 
network services and to increase sales, marketing and general and 
administrative activities. As a result, the Company expects to incur 
substantial additional operating and net losses and substantial negative cash 
flow for at least the next several years. To the extent that increased 
expenses are not accompanied by significant revenues, the Company would 
experience a material adverse effect on its business, prospects, operating 
results, financial condition, and its ability to make principal and interest 
payments on its indebtedness. There can be no assurance that the Company's 
services will ever provide a revenue base adequate to achieve or sustain 
profitability or to generate positive cash flow.


                                       11
<PAGE>

RISKS AND UNCERTAINTIES (CONTINUED):

HISTORICAL LOSSES AND ANTICIPATED FUTURE LOSSES; FLUCTUATIONS IN OPERATING 
RESULTS (CONTINUED)

The Company's annual and quarterly operating results may fluctuate 
significantly in the future as a result of numerous factors, many of which 
are outside the Company's control. Factors that may affect the Company's 
operating results include the rate at which customers subscribe to the 
Company's services and the prices the customers are willing to pay for such 
services, the amount and timing of capital expenditures and other costs 
relating to the expansion of the Company's services and infrastructure, the 
introduction of new services by the Company or its competitors, price 
competition by competitors, the ability of the Company's equipment and 
service suppliers to meet the Company's needs, technical difficulties or 
network downtime, general economic conditions and economic conditions 
specific to the telecommunications services industry. In addition, the 
Company believes its financial performance will depend to a great extent on 
attracting and retaining customers and reducing levels of customer churn, 
which can result from a variety of sources, including employee turnover 
within the Company's customers. Many providers of telecommunications services 
experience high rates of customer churn, and there can be no assurance that 
Rhythms will not experience substantial customer churn.

SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE INDEBTEDNESS

As a result of the 13.5% Senior Discount Note issuance in May 1998, the 
Company is highly leveraged. As of September 30, 1998, the Company had 
approximately $153.0 million in outstanding debt, net of original issue 
discount. In addition, the debt indenture agreement ("Indenture") permits, 
and the Company seeks to structure its future credit facilities, lease 
facilities, and vendor credit facilities so that they are expected to permit, 
the incurrence of certain additional indebtedness. In May 1998, the Company 
entered into a financing arrangement with Sun Financial Group, Inc. for up to 
$24.5 million of additional equipment lease financing. In that regard, the 
Company intends to seek substantial additional indebtedness (including 
secured indebtedness as permitted under the Indenture) in the future for, 
among other things, the construction and expansion of its network 
infrastructure, including the purchase and leasing of equipment, the 
introduction of new service offerings, to obtain access to collocation space 
in ILEC central offices ("COs"), the development and implementation of its 
OSS and the funding of its operating losses. See "Significant Capital 
Requirements; Need for and Uncertainty of Additional Financing."

The degree to which the Company is leveraged could have important 
consequences to the holders of the Company's debt holders including, but not 
limited to, the following: (i) the ability of the Company to pay interest and 
liquidated damages, if any, on, and the redemption price of or the principal 
amount at maturity of, the indebtedness when due may be materially limited or 
impaired; (ii) the Company's ability to obtain additional financing or 
refinancing in the future for capital expenditures, repayment of outstanding 
indebtedness, working capital, acquisitions, general corporate or other 
purposes may be materially limited or impaired; (iii) the Company's cash 
flow, if any, may be unavailable for building the Company's business, as a 
substantial portion of such cash flow may be dedicated to the payment of 
principal and interest on its indebtedness and the failure of the Company to 
generate sufficient cash flow to service such indebtedness could result in a 
default under such indebtedness; (iv) the terms of future permitted 
indebtedness may limit the Company's ability to redeem the its debt in the 
event of a Change of Control; (v) the Company's high degree of leverage may 
make it more vulnerable to economic downturns, may limit its ability to 
withstand competitive pressures and may reduce its flexibility in responding 
to changing business and economic conditions; and (vi) the Company may be 
more highly leveraged than many of its competitors, which may place it at a 
competitive disadvantage.

The Company's ability to make principal and interest payments on it debt will 
depend upon, among other things: (i) the Company's ability to achieve 
significant and sustained growth in cash flow; (ii) the rate of and 
successful commercial deployment of its network services; (iii) the market 
acceptance, customer demand, rate of utilization and pricing of the Company's 
services; (iv) the future operating performance of the Company; (v) the 
Company's ability to successfully complete development, upgrades, and 
enhancements of its network services; (vi) the level of Company expenses; 
(vii) the Company's ability to secure additional financings, as necessary; 
(viii) the Company's ability to complete the rollout of its network services 
on a timely basis; and (ix) economic, financial, competitive, and regulatory 
conditions and other factors. Many of the foregoing matters are beyond the 
Company's control. There can be no assurance that the Company will have 
adequate sources of liquidity to make required payments of principal and 
interest on its indebtedness, whether at or prior to maturity, to finance 
anticipated capital expenditures or to fund working capital requirements. If 
the Company does not have sufficient available resources to repay its 
outstanding indebtedness when it becomes due and payable, the Company may 
find it necessary to reduce the scope of and/or delay the rollout of its 
network services, and/or attempt to restructure or refinance its indebtedness.

RISKS AND UNCERTAINTIES (CONTINUED):

SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE INDEBTEDNESS (CONTINUED)

There can be no assurance that such refinancing will be available, or 
available on reasonable terms, in light of the Company's high leverage and 
other factors. If the Company were unable to obtain refinancing on 
satisfactory terms in order to meet its debt service obligations, it would 
have to consider various other options, such as the sale of equity or other 
options available to it under law, and there can be no assurance that the 
Company will be able to sell equity or take advantage of other options in a 
manner sufficient to meet its debt service obligations.

RESTRICTIVE COVENANTS

The Indenture imposes and will impose significant operating and financial 
restrictions on the Company and any future subsidiaries. These restrictions 
affect, and in certain cases significantly limit or prohibit, among other 
things, the ability of the Company to incur certain additional indebtedness, 
pay dividends and make certain other restricted payments, create liens 
securing certain Indebtedness, to permit Restricted Subsidiaries to pay 
dividends or make other payments, dispose of proceeds of sales of assets, 
issue and sell capital stock of Restricted Subsidiaries, enter into 
transactions with affiliates, engage in certain business activities, permit 
any Restricted Subsidiary to guarantee the payment of any other Indebtedness 
of the Company, engage in certain sale/leaseback transactions, or 
consolidate, merge or transfer all or substantially all of its assets. There 
can be no assurance that such covenants will not adversely affect the 
Company's ability to finance its future operations or capital needs or to 
engage in other business activities. Further, there can be no assurance that 
the Company will have available, or will be able acquire from alternative 
sources of financing, funds sufficient to repurchase its debt in the event of 
a Change of Control.

In addition, any future senior indebtedness incurred by the Company is likely 
to impose similar restrictions on the Company. Failure by the Company or its 
subsidiaries to comply with these restrictions could lead to a default under 
the terms of such indebtedness and the ability of the Company to meet its 
debt service obligations. In the event of such a default, the holders of such 
indebtedness could elect to declare all such indebtedness to be due and 
payable, together with accrued and unpaid interest. In such event, a 
significant portion of the Company's indebtedness may become immediately due 
and payable, and there can be no assurance that the Company would be able to 
make such payments or borrow sufficient funds from alternative sources to 
make any such payment. Even if additional financing could be obtained, there 
can be no assurance that it would be on terms that are acceptable to the 
Company.

SIGNIFICANT CAPITAL REQUIREMENTS; NEED FOR AND UNCERTAINTY OF ADDITIONAL 
FINANCING

The expansion and development of the Company's business will require 
significant capital to fund its capital expenditures, working capital, and 
operating losses. The Company's principal capital expenditures and lease 
payments include the purchase, lease, and installation of network equipment 
such as routers and multiplexers, collocation space, and customer premise 
equipment ("CPE") such as digital "modems." The Company's working capital is 
primarily comprised of accounts receivable, accounts payable, and accrued 
expenses. The Company will need to secure additional financing beyond the net 
proceeds of its debt issuance to enter markets beyond those included in its 
initial rollout plan. In addition, there can be no assurance that the Company 
will be able to finance the rollout strategy in a timely fashion, or at all. 
If demand for the Company's services or its cash flow from operations is less 
than expected, however, the Company may require additional financing prior to 
the completion of its initial rollout. The actual amount and timing of the 
Company's future capital requirements may differ materially from its 
estimates as a result of regulatory, technological, competitive (including 
additional market developments and new opportunities), and other developments 
in its industry. The Company also expects that it will require additional 
financing (or require financing sooner than anticipated) if the Company's 
development plans or projections change or prove to be inaccurate. Due to the 
uncertainty of these factors, actual revenues and costs may vary from 
expected amounts, possibly to a material degree, and such variations are 
likely to affect the Company's future capital requirements.

RISKS AND UNCERTAINTIES (CONTINUED):

SIGNIFICANT CAPITAL REQUIREMENTS; NEED FOR AND UNCERTAINTY OF ADDITIONAL 
FINANCING (CONTINUED)

There can be no assurance that any future equity or debt financing will be 
available to the Company on favorable terms or at all. Recently the financial 
markets have experienced extreme price fluctuations. A market downturn or 
general market uncertainty could have a material adverse effect on the 
Company's ability to secure additional financing. In addition, the Indenture 
contains certain covenants restricting the Company's ability to incur further 
indebtedness, and future borrowing instruments such as credit facilities and 
lease agreements are likely to contain similar or more restrictive covenants 
and will likely require the Company to pledge assets as security for 
borrowings thereunder. In the event that the Company is unable to obtain such 
additional capital or is required to obtain it on unsatisfactory terms, the 
Company will be required to delay the deployment of its network services or 
take or forego actions that could materially adversely affect the Company's 
business, prospects, operating results, financial condition, and its ability 
to make principal and interest payments on its indebtedness. In the event 
that the Company is unable to generate sufficient cash flow and is otherwise 
unable to obtain funds necessary to meet required payments on its 
indebtedness, the Company would be in default under the terms of the 
agreements governing its indebtedness.

EXPANSION RISKS; POSSIBLE INABILITY TO MANAGE GROWTH

The Company's planned rapid expansion of its operations will place a 
significant strain on its management, financial controls, operations systems, 
personnel, and other resources. The Company's ability to manage future 
growth, should it occur, will depend in large part upon its ability to 
monitor its operations, control costs, maintain regulatory compliance, 
maintain effective quality controls, significantly expand its internal 
management and financial control systems, streamline its customer 
qualification and provisioning functions, acquire a significant amount of 
equipment to support its network systems, and attract, assimilate and retain 
qualified personnel. If the Company is successful in implementing its 
marketing strategy, the Company also expects the demands on its network 
infrastructure and the need for technical support resources to grow rapidly, 
and it may experience difficulties responding to customer demand for its 
services and providing technical support in a timely manner and in accordance 
with its customers' expectations. These demands are expected to require not 
only the addition of new management personnel, but also the development of 
additional expertise by existing management personnel and the establishment 
of long-term relationships with third-party service vendors. There can be no 
assurance that the Company will be able to keep pace with any growth, 
successfully implement and maintain its operational and financial systems or 
successfully obtain, integrate and utilize the employees, facilities, 
third-party vendors and equipment, and management, operational and financial 
resources necessary to manage a developing and expanding business in an 
evolving, highly regulated and increasingly competitive industry. If the 
Company is unable to manage growth effectively, its business, prospects, 
operating results, financial condition, and its ability to make principal and 
interest payments on its indebtedness will be materially adversely affected. 
Failure of the Company to manage its future growth effectively could also 
adversely affect the expansion of the Company's customer base and service 
offerings.

TECHNOLOGICAL CHANGE; UNPROVEN NETWORK PERFORMANCE AND SCALABILITY

The telecommunications industry is subject to rapid and significant changes 
in technology, and the effect of technological changes on the business of the 
Company, such as continuing developments in DSL technology and alternative 
technologies for providing high speed data communications, cannot be 
predicted. The Company will be relying in part on third parties (including 
certain of its competitors and potential competitors) for the development of 
and access to communications and networking technology. The effect of 
technological changes on the business of the Company cannot be predicted. The 
Company believes its future success will depend, in part, on its ability to 
anticipate or adapt to such changes and to offer, on a timely basis, services 
that meet customer demands and evolving industry standards. There can be no 
assurance that the Company will obtain access to new technology on a timely 
basis or on satisfactory terms or that the Company will be able to adapt to 
such technological changes, offer such services on a timely basis or 
establish or maintain a competitive position. Any technological change, 
obsolescence or failure to obtain access to important technologies could have 
a material adverse effect on the Company's business, prospects, operating 
results, financial condition, and its ability to make principal and interest

payments on its indebtedness. The Company expects that new products and 
technologies will emerge in the future that will be applicable to the market 
in which the Company competes. Such new products and technologies may be 
superior to and/or render obsolete the products and technologies used by the 
Company. In addition, there can be no assurance that these various products 
and technologies will interoperate successfully or in a manner sufficient for 
the Company to execute its business plan in a timely fashion. The Company 
believes that it will be important for industry standards to be set in its 
markets in order to allow for the compatibility of the various products and 
technologies. There can be no assurance that standards will be set on a 
timely basis or at all.

Many of the products and technologies that the Company intends to use in its 
network services are relatively new and unproven. There can be no assurance 
that those products and technologies will be reliable on a consistent basis. 
In addition, due to the limited deployment of the Company's services, the 
ability of the Company's network to connect and manage a substantial number 
of end users at high transmission speeds is still unknown, and the Company 
faces risks related to its ability to scale its network to service 
significant end users while achieving high performance. There can be no 
assurance that the Company's network will be able to achieve and maintain 
competitive digital transmission speeds. The Company's failure to achieve or 
maintain high speed reliable digital transmissions would significantly reduce 
demand for its services and have a material adverse effect on its business, 
prospects, operating results, financial condition and its ability to make 
principal and interest payments on its indebtedness.

DEPENDENCE ON ILECS

The Company is dependent on the ILECs for: (i) the provision of DSL-capable 
copper loops; (ii) collocation space in ILEC COs; and (iii) in many cases the 
provision of other ILEC services, such as facilities to connect the Rhythms 
Connection Points with the Rhythms Metro Service Centers. In each of these 
areas, the Company faces risks that the ILECs will not have sufficient 
inventory to supply the Company's needs, that the ILECs will delay 
provisioning or that the prices paid by the Company will exceed the ILECs' 
costs of providing the elements and services.

In order to provide DSL connections to customers, the Company must use copper 
loops controlled by the ILECs. In some ILEC COs, there may be an actual 
shortage of DSL-capable copper loops, or the ILECs may claim such a shortage. 
In some cases, the Company may not have alternative means of providing 
service to end users. The Company will also be dependent on the ILECs to 
maintain on an ongoing basis the quality of the copper loops the Company uses 
for its DSL-based services. There can be no assurance that the Company will 
be able to successfully address these issues through business and regulatory 
processes or otherwise. The prices paid by the Company to ILECs for 
DSL-capable copper loops will vary by ILEC and may vary by state. Those rates 
are established by state regulatory commissions in ongoing public hearings, 
based on rate proposals and cost studies submitted by the ILECs and, in some 
cases, by other parties as well and until now they have been based on FCC 
pricing rules which have been overturned by the federal appeals court for the 
Eighth Circuit and will be reviewed by the U.S. Supreme Court. See 
"Government Regulation." ILECs may from time to time propose new rates, which 
will also be decided by the state commissions in public hearings. 
Participating in such hearings is expected to involve significant management 
time and expense. The outcomes of such hearings and rulings may have a 
material adverse effect on the Company. In addition, the Company has not 
established a history of ordering and obtaining the provisioning and repair 
of large volumes of DSL-capable copper loops from ILECs. There can be no 
assurance that either the Company's or the ILECs' OSS will be capable of 
handling a large volume of orders, or that the Company will be successful in 
ordering and provisioning on a large scale.

The Company is dependent on the ILECs to make space available in their COs so 
that the Company can physically collocate its own equipment that connects to 
the ILEC copper loops and is used in providing the Company's DSL services. In 
some COs, there may be an actual shortage of such collocation space, or the 
ILECs may claim such a shortage. In some of these cases, the Company may not 
have alternative means of connecting its DSL equipment with the ILECs' copper 
loops. In some COs, the Company's applications for physical collocation have 
been rejected on the grounds that no such space is available. There can be no 
assurance that additional applications will not be rejected in the future. 
The availability of physical collocation space will also be affected by the 
number of other CLECs requesting collocation. To the extent the Company is 
unable to obtain physical collocation in its targeted ILEC COs, the Company 
may face delays and additional cost in serving certain users, or may not be 
able to offer services in certain locations.

<PAGE>

RISKS AND UNCERTAINTIES (CONTINUED):

DEPENDENCE ON ILECS (CONTINUED)

The price, terms, and conditions under which collocation space is made 
available are determined, depending on the state in which the collocation 
space is located, by state tariffs, State Public Utility Commission, and/or 
interconnection agreements with the ILEC. Interconnection agreements also 
determine the terms and conditions of access to unbundled copper loops (and 
other UNEs), although many of those terms and conditions, including price, 
have been or may be established by the state public utility commissions. 
There can be no assurance that the terms and conditions of interconnection 
agreements that can be negotiated, or that are determined by state 
commissions, will be satisfactory to the Company. The interconnection 
agreements are generally short term, and there can be no assurance that the 
agreements will be renewed on favorable terms or at all. In addition, 
interconnection arrangements and agreements are subject to varying degrees of 
oversight by the state commissions, the FCC and the courts. There can be no 
assurance that these government entities will not modify the terms or prices 
of the Company's interconnection arrangements in ways that would have a 
material adverse effect on the Company. Delays in obtaining interconnection 
agreements would delay the Company's entry into certain markets, which could 
have a material adverse effect on the Company.

The Company will also seek to purchase additional services from ILECs, such 
as transport services, although these services are generally also available 
from other providers. There can be no assurance that the Company will be able 
to obtain the services it requires from the ILECs, or to do so at rates, 
terms, and conditions, including timelines, that are satisfactory to the 
Company. An inability to obtain access to copper loops, collocation space, or 
services from ILECs could have a material adverse effect on the Company's 
business, prospects, operating results, financial condition, and its ability 
to make principal and interest payments on its indebtedness. There can be no 
assurance that disputes will not arise between the Company and the ILECs with 
respect to interconnection agreements or that any such disputes will be 
resolved in favor of the Company.

UNCERTAIN QUALITY AND AVAILABILITY OF COPPER LOOPS

In order to provide service to its customers, the Company must interconnect 
its network with the copper telecommunications loops within the control of 
the ILEC that connect to the end user. In order for DSL connections to 
function properly, these copper loops must be within certain physical 
parameters, including length, minimization of loading coils, minimum numbers 
of bridge taps, and general physical condition. The Company's ability to 
provide DSL-based service to potential customers is highly dependent upon the 
quality, physical condition, and availability of these copper loops, as well 
as the maintenance by the ILECs of the copper loops. The Company believes 
that the current condition of copper loops in many cases will be inadequate 
to permit the Company to fully implement its network services. See 
"Government Regulation." There can be no assurance that the copper loops will 
be of sufficient quality, or that the copper loops will always be maintained 
in such a condition, to allow the Company to fully implement its network 
services. The inability of the Company to implement its network effectively 
or broadly due to the availability, quality or physical condition of copper 
loops would have a material adverse effect on the Company's business, 
prospects, operating results, financial condition, and its ability to make 
principal and interest payments on its indebtedness. Also see "Competition."

GOVERNMENT REGULATION

Some of the services offered by the Company, particularly by its wholly owned 
ACI Corp. and ACI Corp. - Virginia subsidiaries, may be subject to regulation 
at the federal, state, and/or local levels. There can be no assurance that 
current or future federal or state regulations or legislation would not be 
less favorable to the Company than current regulation and legislation and 
therefore have a material adverse impact on the Company's business prospects, 
operating results, financial condition, and ability to make payments on its 
indebtedness. In addition, participation in proceedings setting rules at 
either the federal or state level could consume significant financial and 
managerial resources with no assurance of an outcome favorable to the Company.

RISKS AND UNCERTAINTIES (CONTINUED):

GOVERNMENT REGULATION (CONTINUED)

The Federal Communications Commission ("FCC") prescribes rules applicable to 
interstate communications, including rules implementing the 1996 
Telecommunications Act (the "1996 Act"), a responsibility it shares with the 
state regulatory commissions. The 1996 Act removed many of the remaining 
barriers to local competition, and the FCC's initial rules interpreting the 
Act (the "FCC Order") were generally encouraging to increased local 
competition. A federal appeals court for the 8th Circuit reviewed the FCC 
Order, and overruled some of its provisions, including some rules on pricing 
and nondiscrimination. That ruling is itself to be reviewed by the U.S. 
Supreme Court. In December, 1997 a federal court in Texas ruled 
unconstitutional the 1996 Act's requirement that former Bell System ILECs 
cannot provide interLATA services until they meet certain requirements. This 
could reduce the incentives of those ILECs to cooperate in opening their 
markets to competition. The FCC and other parties have asked the U.S. Supreme 
Court to review this ruling. In May, 1998 a federal court in Washington, D.C. 
ruled that other 1996 Act limitations on Bell System ILECs are not 
unconstitutional. These contrasting rulings may be resolved by the U.S. 
Supreme Court at some point. There can be no assurance that the final outcome 
of these reviews will not have a material adverse impact on the Company. In 
October, 1998, the FCC ruled that DSL services are telecommunications 
services subject to the requirements of the 1996 Act to unbundle such 
services and offer them for resale. In October, 1998, the FCC also issued a 
Notice of Proposed Rulemaking indicating its intention to clarify expanded 
rights of CLECs for collocation, access to copper loops, and various other 
issues of consequence to CLECs deploying DSL services. In November, 1998, the 
FCC ruled that DSL services provided as dedicated access services in 
connection with interstate services such as Internet access are interstate 
services subject to the FCC's jurisdiction. These decisions are currently 
subject to reconsideration and appeal. There can be no assurance that the 
final outcome of these petitions or other proceedings interpreting the 
requirements of the 1996 Act will not have a material adverse impact on the 
Company.

State regulatory commissions prescribe rules applicable to intrastate 
communications, and also set prices for wholesale services and unbundled 
network elements, as well as for other terms and conditions under the 1996 
Act. Rules and prices vary from state to state, and there can be no assurance 
that the rules in the states in which the Company operates will not have a 
material adverse impact on the Company's business. Municipalities and other 
local entities have the authority, where appropriate, to impose zoning and 
franchise requirements, which would become applicable only if and when the 
Company constructs its own facilities in public rights of way. In such an 
event, there could be no assurance that the requirement would not have a 
materially adverse effect on the Company.

DEPENDENCE ON CHANNEL PARTNERS

The Company's strategy relies, in large part, upon the distribution of its 
products and services through Channel Partners. Accordingly, the performance 
of the Company depends substantially on the ability of the Company to 
establish favorable relationships with a large number of key Channel 
Partners, and the performance of the Company's Channel Partners. To date, the 
Company has established relationships with only a limited number of Channel 
Partners. There can be no assurance that the Company will be able to 
establish favorable relationships with Channel Partners or that the 
performance of its Channel Partners will be satisfactory to the Company and 
its customers. The performance of its Channel Partners will be beyond the 
control of the Company. The failure of the Company to establish favorable 
relationships with a large number of key Channel Partners or the 
unsatisfactory performance of its Channel Partners would have a material 
adverse effect on the Company's business, prospects, operating results, 
financial condition, and its ability to make principal and interest payments 
on its indebtedness.

COMPETITION

Rhythms will face competition from many companies with significantly greater 
financial resources, well-established brand names, and large, existing 
installed customer bases. Moreover, the Company expects the level of 
competition to intensify in the future. The Company expects significant 
competition from ILECs, traditional and new IXCs, CAPs, CLECs, cable modem 
service providers, ISPs, and wireless and satellite data service providers. 
ILECs have existing metropolitan area networks and circuit-switched local 
access networks. In addition, most ILECs are establishing their own ISP 
businesses and are in some stage of market trials of DSL-based access 
services.

RISKS AND UNCERTAINTIES (CONTINUED):

COMPETITION (CONTINUED)

Many of the leading traditional IXCs, including MCI Telecommunications 
Corporation (with WorldCom, Inc./MFS Communications Company, Inc./UUNet 
Technologies, Inc.), AT&T Corporation (with Teleport Internet Services/TCG 
CERFnet, Inc. and its announced TCI merger) and Sprint Corporation (with 
EarthLink Network Inc.) are expanding their capabilities to support 
high-speed, end-to-end networking services. The newer IXCs, including 
Williams Companies Inc. ("Williams"), Qwest Communications International, 
Inc. ("Qwest") and Level 3 Communications, Inc., are building and managing 
high bandwidth, nationwide IP-based packet networks and partnering with ISPs 
to offer services directly to the public (Williams/Concentric; IXC 
Communications, Inc./PSINet Inc.; Qwest/Supernet, Inc.). Cable modem service 
providers, like @Home (with its cable partners) are offering or preparing to 
offer high speed Internet access over hybrid fiber networks to consumers, and 
@Work is positioned to do the same for businesses. Several new companies, 
including WinStar Communications, Inc., Teligent, Inc., Teledesic LLC, Hughes 
Space Communications and Iridium World Communications Ltd. are emerging as 
wireless, including satellite-based, data service providers over a variety of 
frequency allocations ranging from 2 GHz to 38 GHz. ISPs, including some with 
significant and even nationwide presences, such as Concentric Network 
Corporation ("Concentric"), Mindspring Enterprises, Inc., and PSINet Inc. 
provide Internet access to residential and business customers, generally over 
the ILECs' circuit switched networks, although some, including HarvardNet, 
Inc. in Massachusetts, have begun offering DSL-based access. Certain CLECs, 
including Covad Communications Company ("Covad") and NorthPoint 
Communications, Inc. ("NorthPoint"), have begun offering DSL-based access 
services, and others are likely to do so in the future.

Many of these competitors are offering (or may soon offer) technologies and 
services that will directly compete with some or all of the Company's service 
offerings. Such technologies include ISDN, DSL, wireless data, and cable 
modems. Some of the competitive factors in the Company's markets include 
transmission speed, reliability of service, breadth of service availability, 
price performance, network security, ease of access and use, content 
bundling, customer support, brand recognition, operating experience, capital 
availability, and exclusive contracts. The Company believes that it compares 
unfavorably with its competitors with regard to, among other things, brand 
recognition, existing relationships with end users, available pricing 
discounts, ILEC CO access, capital availability and exclusive contracts. 
Substantially all of the Company's competitors and potential competitors have 
substantially greater resources than the Company. There can be no assurance 
that the Company will be able to compete effectively in its target markets. A 
failure by the Company to compete effectively would have a material adverse 
effect on the Company's business, prospects, operating results, financial 
condition, and its ability to make principal and interest payments on its 
indebtedness.

UNCERTAIN FEDERAL AND STATE TAX AND OTHER SURCHARGES ON THE COMPANY'S SERVICES

Telecommunications providers are subject to a variety of federal and state 
surcharges and fees on their gross revenues from interstate and intrastate 
services, including regulatory fees, and surcharges related to the support of 
universal service. These surcharges and fees are revised from time to time. 
To the extent that the Company is subject to these surcharges and fees, there 
can be no assurance that such revisions would not have a material adverse 
effect on the Company.

DIGITAL COMMUNICATIONS SIGNAL COMPATIBILITY AND POTENTIAL NETWORK INTERFERENCE

Digital services provided over copper loops can, under some circumstances, 
pose the potential for interference with each other, including communications 
services provided by ILECs and CLECs. Interference, if present, could cause 
degradation of performance of the Company's services or render the Company 
unable to offer its services on selected copper loops. Interference can be 
difficult to detect. The procedures to resolve interference issues between 
CLECs and ILECs are still being developed, and there is no assurance that 
these procedures will be effective. There can be no assurance that the 
Company will successfully negotiate interference resolution procedures with 
ILECs, or that ILECs will not make claims regarding interference nor 
unilaterally take action to resolve interference issues to the detriment of 
the Company's services. Further, interference, if widespread, would have a 
material adverse effect on the Company's reputation, brand image, service 
quality, and customer satisfaction and retention, which would have a material 
adverse effect on the Company's business, prospects, operating results, 
financial condition and its ability to make principal and interest payments 
on its indebtedness.

RISKS AND UNCERTAINTIES (CONTINUED):

DEPENDENCE ON KEY PERSONNEL

The Company's performance is dependent on the performance of its officers and 
key employees, especially its Chief Executive Officer. Members of the 
Company's senior management team have worked together for only a short period 
of time. The Company does not have "key person" life insurance policies on 
any of its employees. The Company does not have employment agreements for 
fixed terms with any of its employees. Any of the Company's employees, 
including its senior management team members, may terminate his or her 
employment with the Company at any time. Given the Company's early stage of 
development, the Company is dependent upon its ability to retain and motivate 
high quality personnel, especially its management. The Company's future 
success also depends on its continuing ability to identify, hire, train, and 
retain highly qualified technical, sales, marketing, and customer service 
personnel. Moreover, the industry in which the Company competes is 
characterized by a high level of employee mobility and aggressive recruiting 
of skilled personnel. There can be no assurance that key personnel will 
continue to be employed by the Company or that the Company will be able to 
attract and retain qualified personnel in the future. Competition for such 
qualified personnel is intense, particularly in software development, network 
engineering, and product management. The inability to attract and retain key 
managerial, technical, sales, marketing, and managerial personnel would have 
a material adverse effect upon the Company's business, prospects, operating 
results, financial condition, and its ability to make principal and interest 
payments on its indebtedness.

DEPENDENCE ON EQUIPMENT SUPPLIERS, INSTALLERS AND FIELD SERVICE PROVIDERS

The Company currently plans to purchase all of its equipment from many 
different vendors and outsource the installation and field service of its 
networks to third parties. Any reduction or interruption in supply from any 
of its suppliers or interruption in service from any significant installer or 
field service provider could have a disruptive effect on the Company. 
Although multiple manufacturers currently produce or are developing equipment 
that will meet the Company's current and anticipated requirements, there can 
be no assurance that the Company's suppliers will be able to manufacture and 
deliver the amount of equipment ordered or that such supply will be 
sufficient to meet demand. In addition, the pricing of the equipment 
purchased by the Company may substantially increase over time (increasing the 
costs paid in the future by the Company) or decrease over time (providing 
later market entrants with a cost advantage over the Company). The 
availability and pricing of the equipment purchased and technology licensed 
by the Company may be adversely affected if its suppliers or licensors enter 
into competition with it, or if its competitors enter into exclusive or 
restrictive arrangements with the suppliers or licensors. Any shortages in 
supply of equipment or personnel, or quality issues relating to any of these 
third parties would have a material adverse effect on the Company's business, 
prospects, operating results, financial condition, and its ability to make 
principal and interest payments on its indebtedness.

DEPENDENCE ON LEASED TRANSPORT FACILITIES

The Company seeks to lease from third parties transport capacity to connect 
its network facilities, and is dependent upon the availability of fiber optic 
transmission facilities owned by IXCs, ILECs, CLECs and other fiber optic 
transport providers who lease their fiber optic networks to service 
providers, such as the Company. Many of these entities are, or may become, 
competitors of the Company. See "Competition." The risks inherent in this 
approach include, but are not limited to, the possible inability to negotiate 
and renew favorable supply agreements and dependence on the timeliness of the 
IXCs, ILECs, CLECs or other fiber optic transport providers in processing the 
Company's orders for customers who seek to use the Company's services. 
Moreover, there can be no assurance that fiber optic transport providers 
whose networks are being leased by the Company will be able to maintain 
existing permits and rights-of-way or to obtain and maintain the other 
permits and rights-of-way needed to develop and operate existing and future 
networks.

RISKS AND UNCERTAINTIES (CONTINUED):

INTELLECTUAL PROPERTY PROTECTION

The Company relies upon a combination of licenses, confidentiality agreements 
and other contractual covenants to establish and protect its technology and 
other intellectual property rights. The Company has applied for trademarks 
and servicemarks on certain terms and symbols that it believes are important 
for its business. The Company currently has no patents or patent applications 
pending. There can be no assurance that the steps taken by the Company will 
be adequate to prevent misappropriation of its technology or other 
intellectual property, or that the Company's competitors will not 
independently develop technologies that are substantially equivalent or 
superior to the Company's technology. There can be no assurance that third 
parties will not assert infringement claims against the Company and that, in 
the event of an unfavorable ruling on any such claim, a license or similar 
agreement to utilize technology relied upon by the Company in the conduct of 
its business will be available to the Company on reasonable terms or at all. 
The loss of such rights or failure to obtain any necessary licenses or 
agreements may have a material adverse effect on the Company's business, 
prospects, financial condition and results of operations, and its ability to 
make principal and interest payments on its indebtedness. The Company also 
relies on unpatented trade secrets and know-how to maintain its competitive 
positions, which it seeks to protect, in part, by confidentiality agreements 
with employees, consultants and others. There can be no assurance that these 
agreements will not be breached or terminated, that the Company will have 
adequate remedies for any breach, or that the Company's trade secrets will 
not otherwise become known or be independently discovered by competitors. The 
Company's management personnel were previously employed by other 
telecommunications companies. In many cases, these individuals are conducting 
activities for the Company in areas similar to those in which they were 
involved prior to joining the Company. As a result, the Company, as well as 
these individuals, could be subject to allegations of violation of trade 
secrets and other similar claims.

CONCENTRATION OF OWNERSHIP; VOTING AGREEMENT; POTENTIAL CONFLICTS OF INTEREST

The Company's executive officers and directors, together with the Brentwood 
Entities, the KPCB Entities, the Enterprise Entities, the Sprout Entities, 
and Enron beneficially own over 97.6% of the outstanding Common Stock of the 
Company (assuming conversion of all outstanding Preferred Stock into Common 
Stock and without giving effect to the exercise of warrants). Accordingly, 
these stockholders are able to determine the composition of the Company's 
Board of Directors, retain the voting power to approve all matters requiring 
stockholder approval, and continue to have significant influence over the 
affairs of the Company. This concentration of ownership could have the effect 
of delaying or preventing a change in control of the Company.

Certain decisions concerning the operations or financial structure of the 
Company may present conflicts of interest between these investors and the 
debt holders. For example, if the Company encounters financial difficulties 
or is unable to pay its debts as they mature, the interest of these investors 
may conflict with those of the debt holders. In addition, these investors may 
have an interest in pursuing acquisitions, divestitures, financings, or other 
transactions and business strategies that, in their judgment, could enhance 
their equity investment in the Company, even though such transactions might 
involve increased risk to the debt holders.

RISK OF SYSTEM FAILURE; NETWORK SECURITY RISK

The Company's operations are dependent upon its ability to avoid damages from 
fires, earthquakes, floods, power losses, telecommunications failures, 
network software flaws, transmission cable cuts, and similar events. The 
occurrence of a natural disaster or other unanticipated problem at the 
Company's owned or leased facilities could cause interruptions in the 
services provided by the Company. Additionally, failure of an ILEC or other 
service provider, such as a CLEC, to provide communications capacity required 
by the Company, as a result of a natural disaster, operational disruption or 
any other reason, could cause interruptions in the services provided by the 
Company. Any damage or failure that causes interruptions in the Company's 
operations could have a material adverse effect on the Company's business, 
prospects, operating results, financial condition, and its ability to make 
principal and interest payments on its indebtedness.


                                       20
<PAGE>

RISKS AND UNCERTAINTIES (CONTINUED):

RISK OF SYSTEM FAILURE; NETWORK SECURITY RISK (CONTINUED)

Despite the implementation of security measures, the Company's network may be 
vulnerable to unauthorized access, computer viruses, and other disruptive 
problems. Corporate networks and ISPs have in the past experienced, and may 
in the future experience, interruptions in service as a result of accidental 
or intentional actions of Internet users, current and former employees, and 
others. Unauthorized access could also potentially jeopardize the security of 
confidential information stored in the computer systems of the Company's 
customers, which might result in liability of the Company to its customers, 
and also might deter potential customers. Although the Company intends to 
implement security measures that are standard within the telecommunications 
industry, there can be no assurance that it will implement such measures in a 
timely manner or to the degree that may be compatible with its customers' 
expectations, or that, if and when implemented, such measures will not be 
circumvented. Eliminating computer viruses and alleviating other security 
problems may require interruptions, delays or cessation of service to the 
Company's customers and such customers' end users. Any of the foregoing 
factors relating to network security could have a material adverse effect on 
the Company's business, prospects, operating results, financial condition, 
and its ability to make principal and interest payments on its indebtedness.

PAYMENT UPON A CHANGE OF CONTROL

The Indenture provides that, upon the occurrence of a Change of Control, the 
Company will be required to make an offer to repurchase all of the related 
indebtedness issued and then outstanding under the Indenture at a purchase 
price in cash equal to 101% of the Accreted Value thereof plus accrued and 
unpaid interest and Liquidated Damages, if any, thereon to the date of 
repurchase. If a Change of Control were to occur, there can be no assurance 
that the Company would be able to repay all of its obligations under the 
Indenture and any other indebtedness that may become payable in such event. 
In addition, the ability of the Company to repurchase debt upon a Change of 
Control may be restricted by the terms of other indebtedness of the Company. 
There can be no assurance that the Company would be able to refinance on 
commercially reasonable terms, if at all, any of such obligations, and 
consequently no assurance can be given that the Company would be able to 
repurchase any of the outstanding debt upon a Change of Control.

The Warrant Agreement provides that, upon the occurrence of a "Repurchase 
Event" (as defined in the warrant agreement), the Company must make an offer 
to repurchase for cash all outstanding warrants (a "Repurchase Offer"). In 
such event, properly surrendered warrants are to be repurchased by the 
Company at a price in cash equal to the value on the Valuation Date (as 
defined in the Warrant Agreement) relating thereto of the Warrant Shares (and 
other securities issuable upon exercise of the warrants), had the warrants 
then been exercised, less the Exercise Price therefor. The requirement that 
the Company make a Repurchase Offer will, unless appropriate consents or 
waivers are obtained, require the Company to repay all indebtedness of the 
Company then outstanding which by its terms would prohibit such Repurchase 
Offer. There can be no assurance that the Company will have sufficient funds 
available at the time of any Repurchase Event to repurchase the warrants and 
repay any such indebtedness, as well as to repurchase any other securities of 
the Company that by their terms require the Company to repurchase such 
securities upon the occurrence of such an event. The triggering of such 
payment requirements by the Company upon the occurrence of a Repurchase Event 
could have a material adverse effect on the Company's ability to make 
principal and interest payments on its indebtedness.

INVESTMENT COMPANY ACT CONSIDERATIONS

After issuing its 13.5% Senior Discount Notes, the Company had substantial 
cash and short-term investments. The Company invested the proceeds from the 
Issuance so as to preserve capital (for use in the rollout of the Company's 
network) by investing it in short-term instruments consistent with prudent 
cash management and not primarily for the purpose of achieving investment 
returns. Investment in securities primarily for the purpose of achieving 
investment returns could result in the Company's being treated as an 
"investment company" under the Investment Company Act of 1940, as amended 
(the "1940 Act"). The 1940 Act requires the registration of, and imposes 
various substantive restrictions on, certain companies that are, or hold 
themselves out as being, engaged primarily, or propose to engage primarily, 
in the business of investing, reinvesting, or trading in securities, or that 
fail certain statistical tests regarding composition of assets and sources of 
income and are not primarily engaged in businesses other than investing, 
reinvesting, owning, holding, or trading securities.

<PAGE>

RISKS AND UNCERTAINTIES (CONTINUED):

INVESTMENT COMPANY ACT CONSIDERATIONS (CONTINUED)

The Company believes that it is primarily engaged in a business other than 
investing, reinvesting, owning, holding, or trading securities and, 
therefore, is not an investment company within the meaning of the 1940 Act. 
If the Company were required to register as an investment company under the 
1940 Act, it would become subject to substantial regulation with respect to 
its capital structure, management, operations, transactions with affiliated 
persons (as defined in the 1940 Act), and other matters. Application of the 
provisions of the 1940 Act to the Company would have a material adverse 
effect on the Company's business, prospects, financial condition, results of 
operations, and its ability to make principal and interest payments on its 
indebtedness.

RISK REGARDING FORWARD-LOOKING STATEMENTS

This document contains "forward-looking statements" within the meaning of 
Section 27A of the Securities Act and Section 21E of the Exchange Act. Such 
forward-looking statements generally can be identified by the use of 
forward-looking terminology such as "believes," "expects," "may," "will," 
"should," or "anticipates" or the negative thereof or other variations 
thereon or comparable terminology, or by discussion of strategy, that involve 
risks and uncertainties. Management wishes to caution the reader that these 
forward-looking statements, such as relates to the Company's network rollout 
plans and strategies and statements regarding the development of the 
Company's business, the markets for the Company's services and products, the 
Company's anticipated capital expenditures, possible changes in regulatory 
requirements, and other statements contained herein regarding matters that 
are not historical facts, are only predictions and estimates regarding future 
events and circumstances. Any forward-looking statements contained herein are 
subject to material risks and uncertainties, many of which are beyond the 
control of the Company. Market conditions and the Company's actual results 
may differ materially from the market conditions and results discussed in 
these statements.

ORIGINAL ISSUE DISCOUNT

The 13.5% Senior Discount Notes were issued with substantial original issue 
discount for U.S. federal income tax purposes. This debt may be subject to 
the high yield discount obligation rules, which will defer and may, in part, 
eliminate the Company's ability to deduct for U.S. federal income tax 
purposes the original issue discount attributable to the debt. Accordingly, 
the Company's after-tax cash flow might be less than if the original issue 
discount on the debt was deductible when it accrued. If a bankruptcy case 
were commenced by or against the Company under the Bankruptcy Code of 1978, 
as amended (the "Bankruptcy Code"), the claim of a debt holder may be limited 
to an amount equal the sum of (i) the initial offering price and (ii) that 
portion of the original issue discount that is not deemed to constitute 
"unmatured interest" for purposes of the Bankruptcy Code. Any original issue 
discount that was not amortized as of the date of any such bankruptcy filing 
would constitute "unmatured interest."

IMPACT OF THE YEAR 2000 ISSUE

The Year 2000 ("Y2K") issue is the result of computer programs that were 
written using two digits, rather than four, to define the applicable year. 
Any computer programs that contain date-sensitive software may recognize a 
date using "00" as the year 1900 rather than the year 2000, which could 
result in system failures or miscalculations causing disruptions of 
operations, including, among other things, the Company's ability to process 
customer orders, monitor its network, complete and record financial 
transactions, produce invoices, pay vendors, or engage in similar normal 
business activities, which could have a material adverse effect on the 
Company.

The Company's detailed plan (the "Y2K Plan") to address possible Y2K 
compliance issues takes into consideration internally developed and 
externally developed software, as well as products, systems and services of 
the Company's vendors and other business relations. The Company is currently 
in the process of implementing its Y2K Plan and expects to be Y2K compliant 
by December 31, 1998, or, if not compliant, expects to identify any areas of 
non-compliance and to develop appropriate solutions. Solutions to 
non-compliance may include reselection of vendors or changes in products or 
services used. .Due to the progress to date in implementing its Y2K Plan, 
including the selection of business partners and relationships that have 
represented to be Y2K compliant, and the fact that the Company's short length 
of time in business precludes it from having legacy systems, the cost impact 
of becoming Y2K compliant is expected to be minimal.

                       RESTATED CERTIFICATE OF INCORPORATION
                          OF RHYTHMS NETCONNECTIONS INC.,
                               a Delaware Corporation

       Rhythms NetConnections Inc., a corporation organized and existing

of Incorporation with the Secretary of State was February 27, 1997.

       2.     This Restated Certificate of Incorporation restates and amends 
the provisions of the original Certificate of Incorporation of this 
corporation as heretofore in effect and was duly adopted by the corporation's 
Board of Directors in accordance with Sections 241 and 245 of the General 
Corporation Law of the State of Delaware.

       3.     The text of the Certificate of Incorporation is hereby restated 
to read as herein set forth in full:
                                       
                                    ARTICLE I

       The name of this corporation is Rhythms NetConnections Inc.

                                    ARTICLE II

       The address of the registered office of the corporation in the State 
of Delaware is 30 Old Rudnick Lane, City of Dover, County of Kent 19901.  The

                                     ARTICLE IV

       A.     CLASSES OF STOCK.  This corporation is authorized to issue two 
classes of stock to be designated, respectively, "Common Stock" and 
"Preferred Stock."  The total number of shares 

<PAGE>

which the corporation is authorized to issue is Thirty-Nine Million Eight 
Hundred Fifty-Four Thousand Five Hundred Ninety-Three (39,854,593) shares.  
Twenty-Two Million Nine Hundred Nine Thousand Six Hundred Fifty (22,909,650) 
shares shall be Common Stock, $0.001 par value per share and Sixteen Million 
Nine Hundred Forty-Four Thousand Nine Hundred Forty-Three (16,944,943) shares 
shall be Preferred Stock, $0.001 par value per share.

       B.     RIGHTS, PREFERENCES AND RESTRICTIONS OF PREFERRED STOCK.  The 
Preferred Stock authorized by this Restated Certificate of Incorporation may 
be issued from time to time in series.  The rights, preferences, privileges, 
and restrictions granted to and imposed on (i) the Series A Preferred Stock, 
which series shall consist of 12,900,000 shares and (ii) the Series B 
Preferred Stock, which series shall consist of 4,044,943 shares, are as set 
forth below in this Article IV(B).  The Board of Directors is hereby 
authorized to fix or alter the rights, preferences, privileges and 
restrictions granted to or imposed upon additional series of Preferred Stock, 
and the number of shares constituting any such series and the designation 
thereof, or of any of them.  Subject to compliance with applicable protective 
voting rights which have been or may be granted to the Preferred Stock or 
series thereof in Certificates of Determination or the corporation's Restated 
Certificate of Incorporation ("Protective Provisions"), but notwithstanding 
any other rights of the Preferred Stock or any series thereof, the rights, 
privileges, preferences and restrictions of any such additional series may be 
subordinated to, pari passu with (including, without limitation, inclusion in 
provisions with respect to liquidation and acquisition preferences, 
redemption and/or approval of matters by vote or written consent), or senior 
to any of those of any present or future class or series of Preferred or 
Common Stock.  Subject to compliance with applicable Protective Provisions, 
the Board of Directors is also authorized to increase or decrease the number 
of shares of any series (other than the Series A Preferred Stock or Series B 
Preferred Stock) prior or subsequent to the issue of that series, but not 
below the number of shares of such series then outstanding. In case the 
number of shares of any series shall be so decreased, the shares constituting 
such decrease shall resume the status which they had prior to the adoption of 
the resolution originally fixing the number of shares of such series.

              1.   DIVIDEND PROVISIONS.

                   (a)  Subject to the rights of series of Preferred Stock 
which may from time to time come into existence, the holders of shares of 
Series A Preferred Stock and Series B Preferred Stock shall be entitled to 
receive dividends, out of any assets legally available therefor, prior and in 
preference to any declaration or payment of any dividend (payable other than 
in: (a) Common Stock or other securities and rights convertible into or 
entitling the holder thereof to receive, directly or indirectly, additional 
shares of Common Stock of this corporation; or (b) capital stock of other 
persons (including without limitation subsidiaries of this corporation) or 
options or rights to purchase any such capital stock) on the Common Stock of 
this corporation, at the rate of (i) $0.08 per share of Series A Preferred 
Stock per annum and $0.356 per share of Series B Preferred Stock per annum, 
or (ii) if greater, the amount per annum which would be paid per share of 
Series A Preferred Stock and Series B Preferred Stock, as the case may be, on 
the number of shares of Common Stock into which such share is convertible as 
of the record date fixed for determination of the stockholders entitled to 
receive such distribution (assuming conversion of all convertible Preferred 
Stock), payable quarterly when, as and if declared by the Board of Directors. 
Such dividends shall not be cumulative.  Dividends paid in a form other than 

                                       -2-

<PAGE>

cash shall be deemed to be the fair value thereof as determined by the Board 
of Directors irrespective of any accounting treatment.

                   (b)  In the event this corporation shall declare a 
distribution payable in capital stock of other persons or options or rights 
to purchase any such capital stock, then, (i) in the event this corporation 
distributes at the same time (A) common stock of another person and (B) 
Series A preferred stock and Series B preferred stock of such other person, 
with rights, preferences, privileges and restrictions substantially the same 
as the Series A Preferred Stock and Series B Preferred Stock, and the number 
of shares of common stock, Series A preferred stock and Series B preferred 
stock distributed are in substantially the same relative proportions as this 
corporation's then outstanding shares of Common Stock, Series A Preferred 
Stock and Series B Preferred Stock, then (V) all such common stock shall be 
distributed to the Common Stock, (W) all such Series A preferred stock shall 
be distributed to the Series A Preferred Stock, and (X) all such Series B 
preferred stock shall be distributed to the Series B Preferred Stock, and 
(ii) in all other cases the holders of the Series A Preferred Stock and 
Series B Preferred Stock shall be entitled (together with the Common Stock) 
to a proportionate share, and no more, of any such distribution as though the 
holders of the Series A Preferred Stock and Series B Preferred Stock were the 
holders of the number of shares of Common Stock of this corporation into 
which their respective shares of Series A Preferred Stock and Series B 
Preferred Stock are convertible as of the record date fixed for the 
determination of the stockholders entitled to receive such distribution.

              2.   LIQUIDATION PREFERENCE.

                   (a)  In the event of any liquidation, dissolution or 
winding up of this corporation, either voluntary or involuntary, subject to 
the rights of series of Preferred Stock which may from time to time come into 
existence, the holders of Series A Preferred Stock and Series B Preferred 
Stock shall be entitled to receive, prior and in preference to any 
distribution of any of the assets of this corporation to the holders of 
Common Stock by reason of their ownership thereof, an amount per share equal 
to the sum of (i) $1.00 for each outstanding share of Series A Preferred 
Stock and $4.45 for each outstanding share of Series B Preferred Stock 
(hereafter referred to as the "Original Series A Issue Price" and "Original 
Series B Issue Price," respectively), and (ii) an amount equal to declared 
but unpaid dividends on such share.  If upon the occurrence of such event, 
the assets and funds thus distributed among the holders of the Series A 
Preferred Stock and Series B Preferred Stock shall be insufficient to permit 
the payment to such holders of the full aforesaid preferential amounts, then, 
subject to the rights of series of Preferred Stock which may from time to 
time come into existence, the entire assets and funds of the corporation 
legally available for distribution shall be distributed ratably among the 
holders of the Series A Preferred Stock and Series B Preferred Stock in 
proportion to the product of the liquidation preference of each such share 
and the number of such shares owned by each such holder.

                   (b)  After the distributions described in subsection (a) 
above have been paid, subject to the rights of series of Preferred Stock 
which may from time to time come into existence, the remaining assets of the 
corporation available for distribution to stockholders shall be distributed 
among the holders of Common Stock pro rata based on the number of shares of 
Common Stock held by each.

                                     -3-

                   (c)  A consolidation or merger reorganization of this 
corporation with or into any other corporation or corporations, or the 
effectuation by the corporation of a transaction or series of related 
transactions in which more than 50% of the voting power of the corporation is 
disposed of, or a sale, conveyance or disposition of all or substantially all 
of the assets of this corporation shall be deemed to be a liquidation within 
the meaning of this Section 2; provided, however, that the sale and issuance 
of shares of Series A Preferred Stock pursuant to that certain Series A 
Preferred Stock Purchase Agreement dated July 3, 1997 and the sale and 
issuance of Series B Preferred Stock pursuant to that certain Series B 
Preferred Stock Purchase Agreement dated on or about March  ___, 1998 shall 
not be deemed a liquidation under this Section 2.

              3.   CONVERSION.  The holders of the Series A Preferred Stock 
and Series B Preferred Stock shall have conversion rights as follows (the 
"Conversion Rights"):

                   (a)  RIGHT TO CONVERT.

                        i)   Subject to subsection (c), each share of Series 
A Preferred Stock and each share of Series B Preferred Stock shall be 
convertible, at the option of the holder thereof, at any time after the date 
of issuance of such share at the office of this corporation or any transfer 
agent for the Series A Preferred Stock and Series B Preferred Stock, into 
such number of fully paid and nonassessable shares of Common Stock as is 
determined by dividing (A) the Original Series A Issue Price for each share 
of Series A Preferred Stock and (B) the Original Series B Issue Price for 
each share of Series B Preferred Stock, by the Conversion Price at the time 
in effect for such share.  The initial Conversion Price per share for shares 
of Series A Preferred Stock shall be the Original Series A Issue Price and 
the initial Conversion Price per share for shares of Series B Preferred Stock 
shall be the Original Series B Issue Price; provided, however, that the 
Conversion Price for the Series A Preferred Stock and Series B Preferred 
Stock shall be subject to adjustment as set forth in subsection 3(c).

                        ii)  Each share of Series A Preferred Stock and each 
share of Series B Preferred Stock shall automatically be converted into 
shares of Common Stock at the Conversion Price at the time in effect for such 
Series A Preferred Stock and Series B Preferred Stock immediately upon the 
earlier of (A) the consummation of the corporation's sale of its Common Stock 
in a bona fide, firm commitment underwriting pursuant to a registration 
statement under the Securities Act of 1933, as amended, the public offering 
price of which was not less than $20,000,000 in the aggregate or (B) the date 
upon which the corporation obtains the consent of the holders of 66-2/3% of 
the then outstanding shares of Preferred Stock.

                   (b)  MECHANICS OF CONVERSION.  Before any holder of Series 
A Preferred Stock or Series B Preferred Stock shall be entitled to convert 
the same into shares of Common Stock, such holder shall surrender the 
certificate or certificates therefor, duly endorsed, at the office of this 
corporation or of any transfer agent for the particular series of Preferred 
Stock, and shall give written notice by mail, postage prepaid, to this 
corporation at its principal corporate office, of the election to convert the 
same and shall state therein the name or names in which the certificate or 
certificates for shares of Common Stock are to be issued.  This corporation 
shall, as soon as practicable thereafter, issue and deliver at such office to 
such holder of Series A Preferred Stock and/or Series B Preferred Stock, or 
to the nominee or nominees of such holder, a 

                                     -4-

<PAGE>

certificate or certificates for the number of shares of Common Stock to which 
such holder shall be entitled as aforesaid.  Such conversion shall be deemed 
to have been made immediately prior to the close of business on the date of 
such surrender of the shares of Series A Preferred Stock and/or Series B 
Preferred Stock to be converted, and the person or persons entitled to 
receive the shares of Common Stock issuable upon such conversion shall be 
treated for all purposes as the record holder or holders of such shares of 
Common Stock as of such date.  If the conversion is in connection with an 
underwritten offer of securities registered pursuant to the Securities Act of 
1933, the conversion may, at the option of any holder tendering such 
Preferred Stock for conversion, be conditioned upon the closing with the 
underwriter of the sale of securities pursuant to such offering, in which 
event the person(s) entitled to receive the Common Stock issuable upon such 
conversion of the Series A Preferred Stock and/or Series B Preferred Stock 
shall not be deemed to have converted such Series A Preferred Stock and/or 
Series B Preferred Stock until immediately prior to the closing of such sale 
of securities.

                   (c)  CONVERSION PRICE ADJUSTMENTS OF PREFERRED STOCK. The 
Conversion Prices of the Series A Preferred Stock and Series B Preferred 
Stock shall be subject to adjustment from time to time as follows:

                        i)   A.   Upon each issuance by the corporation of 
any Additional Stock (as defined below), after the date upon which any shares 
of the Series A Preferred Stock or Series B Preferred Stock were first issued 
(the "Purchase Date" with respect to such series), without consideration or 
for a consideration per share less than the Conversion Price for such series 
in effect immediately prior to the issuance of such Additional Stock, the 
Conversion Price for such series in effect immediately prior to each such 
issuance shall forthwith (except as otherwise provided in this clause (i)) be 
adjusted to a price determined by multiplying such Conversion Price by a 
fraction, the numerator of which shall be the number of shares of Common 
Stock outstanding immediately prior to such issuance (including, without 
limitation, the number of shares of Common Stock issuable upon the conversion 
of all outstanding Preferred Stock and all other convertible securities and 
the exercise of all outstanding options, warrants or other rights to purchase 
Common Stock or other securities convertible into Common Stock) plus the 
number of shares of Common Stock which the aggregate consideration received 
by the corporation for such issuance would purchase at such Conversion Price; 
and the denominator of which shall be the number of shares of Common Stock 
outstanding immediately prior to such issuance (including, without 
limitation, the number of shares of Common Stock issuable upon the conversion 
of all outstanding Preferred Stock and all other convertible securities and 
the exercise of all outstanding options, warrants or other rights to purchase 
Common Stock or other securities convertible into Common Stock) plus the 
number of shares of such Additional Stock.

                             B.   No adjustment of the Conversion Price for 
the Series A Preferred Stock or Series B Preferred Stock shall be made in an 
amount less than one cent per share, provided that any adjustments which are 
not required to be made by reason of this sentence shall be carried forward 
and shall be either taken into account in any subsequent adjustment made 
prior to 3 years from the date of the event giving rise to the adjustment 
being carried forward, or shall be made at the end of 3 years from the date 
of the event giving rise to the adjustment being carried forward.  Except to 
the limited extent provided for in subsections 3(c)(i)(E)(3) and 
3(c)(i)(E)(4), no adjustment of such Conversion Price pursuant to this 

                                     -5-

<PAGE>

subsection 3(c)(i) shall have the effect of increasing the Conversion Price 
above the Conversion Price in effect immediately prior to such adjustment.

                             C.   In the case of the issuance of Common Stock 
for cash, the consideration shall be deemed to be the amount of cash paid 
therefor before deducting any reasonable discounts, commissions or other 
expenses allowed, paid or incurred by this corporation for any underwriting 
or otherwise in connection with the issuance and sale thereof.

                             D.   In the case of the issuance of the Common 
Stock for a consideration in whole or in part other than cash, the 
consideration other than cash shall be deemed to be the fair value thereof as 
determined by the Board of Directors irrespective of any accounting treatment.

                             E.   In the case of the issuance (whether 
before, on or after the applicable Purchase Date) of options to purchase or 
rights to subscribe for Common Stock, securities by their terms convertible 
into or exchangeable for Common Stock or options to purchase or rights to 
subscribe for such convertible or exchangeable securities, the following 
provisions shall apply for all purposes of this subsection 3(c)(i) and 
subsection 3(c)(ii):

                                  1.   The aggregate maximum number of shares 
of Common Stock deliverable upon exercise (assuming the satisfaction of any 
conditions to exercisability, including without limitation, the passage of 
time, but without taking into account potential antidilution adjustments) of 
such options to purchase or rights to subscribe for Common Stock shall be 
deemed to have been issued at the time such options or rights were issued and 
for a consideration equal to the consideration (determined in the manner 
provided in subsections 3(c)(i)(C) and (c)(i)(D)), if any, received by the 
corporation upon the issuance of such options or rights plus the exercise 
price provided in such options or rights (without taking into account 
potential antidilution adjustments) for the Common Stock covered thereby.

                                  2.   The aggregate maximum number of shares 
of Common Stock deliverable upon conversion of or in exchange (assuming the 
satisfaction of any conditions to convertibility or exchangeability, 
including, without limitation, the passage of time, but without taking into 
account potential antidilution adjustments) for any such convertible or 
exchangeable securities or upon the exercise of options to purchase or rights 
to subscribe for such convertible or exchangeable securities and subsequent 
conversion or exchange thereof shall be deemed to have been issued at the 
time such securities were issued or such options or rights were issued and 
for a consideration equal to the consideration, if any, received by the 
corporation for any such securities and related options or rights (excluding 
any cash received on account of accrued interest or accrued dividends), plus 
the additional consideration, if any, to be received by the corporation 
(without taking into account potential antidilution adjustments) upon the 
conversion or exchange of such securities or the exercise of any related 
options or rights (the consideration in each case to be determined in the 
manner provided in subsections 3(c)(i)(C) and (c)(i)(D)).

                                  3.   In the event of any change in the 
number of shares of Common Stock deliverable or in the consideration payable 
to this corporation upon exercise of such options or rights or upon 
conversion of or in exchange for such convertible or 

                                     -6-

<PAGE>

exchangeable securities, including, but not limited to, a change resulting 
from the antidilution provisions thereof, the Conversion Price of the Series 
A Preferred Stock and Series B Preferred Stock, as applicable, and to the 
extent in any way affected by or computed using such options, rights or 
securities, shall be recomputed to reflect such change, but no further 
adjustment shall be made for the actual issuance of Common Stock or any 
payment of such consideration upon the exercise of any such options or rights 
or the conversion or exchange of such securities.

                                  4.   Upon the expiration of any such 
options or rights, the termination of any such rights to convert or exchange 
or the expiration of any options or rights related to such convertible or 
exchangeable securities, the Conversion Price of the Series A Preferred Stock 
and Series B Preferred Stock, as applicable, to the extent in any way 
affected by or computed using such options, rights or securities or options 
or rights related to such securities, shall be recomputed to reflect the 
issuance of only the number of shares of Common Stock (and convertible or 
exchangeable securities which remain in effect) actually issued upon the 
exercise of such options or rights, upon the conversion or exchange of such 
securities or upon the exercise of the options or rights related to such 
securities.

                                  5.   The number of shares of Common Stock 
deemed issued and the consideration deemed paid therefor pursuant to 
subsections 3(c)(i)(E)(1) and (2) shall be appropriately adjusted to reflect 
any change, termination or expiration of the type described in either 
subsection 3(c)(i)(E)(3) or (4).

                        ii)  "Additional Stock" shall mean any shares of 
Common Stock issued (or deemed to have been issued pursuant to subsection 
3(c)(i)(E)) by this corporation after the Purchase Date other than

                             A.   Common Stock issued pursuant to a 
transaction described in subsection 3(c)(iii) hereof,

                             B.   shares of Common Stock issuable or issued 
to employees, consultants or directors of this corporation directly or 
pursuant to a stock option plan or restricted stock plan approved by the 
Board of Directors of this corporation, or

                             C.   shares of Common Stock issued upon 
conversion of the Series A Preferred Stock or Series B Preferred Stock, or

                             D.   shares of Common Stock issued or issuable 
(I) in a public offering before or in connection with which all outstanding 
shares of Series A Preferred Stock and Series B Preferred Stock will be 
converted to Common Stock or (II) upon exercise of warrants or rights granted 
to underwriters in connection with such a public offering, or

                             E.   shares of Common Stock issued or issuable 
to persons or entities with which the corporation has business relationships 
provided such issuances are for other than primarily equity financing 
purposes approved by the Board of Directors.

                        iii) In the event the corporation should at any time 
or from time to time after the Purchase Date fix a record date for the 
effectuation of a split or subdivision of 

                                     -7-

<PAGE>

the outstanding shares of Common Stock or the determination of holders of 
Common Stock entitled to receive a dividend or other distribution payable in 
additional shares of Common Stock or other securities or rights convertible 
into, or entitling the holder thereof to receive directly or indirectly, 
additional shares of Common Stock (hereinafter referred to as "Common Stock 
Equivalents") without payment of any consideration by such holder for the 
additional shares of Common Stock or the Common Stock Equivalents (including 
the additional shares of Common Stock issuable upon conversion or exercise 
thereof), then, as of such record date (or the date of such dividend 
distribution, split or subdivision if no record date is fixed), the 
Conversion Price of the Series A Preferred Stock and Series B Preferred Stock 
then in effect shall be appropriately decreased so that the number of shares 
of Common Stock issuable on conversion of each share of such series shall be 
increased in proportion to such increase of the aggregate of shares of Common 
Stock outstanding and those issuable with respect to such Common Stock 
Equivalents with the number of shares issuable with respect to Common Stock 
Equivalents determined from time to time in the manner provided for deemed 
issuances in subsection 3(c)(i)(E).

                        iv)  If the number of shares of Common Stock 
outstanding at any time after the Purchase Date is decreased by a combination 
of the outstanding shares of Common Stock, then, following the record date of 
such combination, the Conversion Price for the Series A Preferred Stock and 
Series B Preferred Stock then in effect shall be appropriately increased so 
that the number of shares of Common Stock issuable on conversion of each 
share of such series shall be decreased in proportion to such decrease in 
outstanding shares.

                   (d)  RECAPITALIZATIONS.  If at any time or from time to 
time there shall be a recapitalization of the Common Stock (other than a 
subdivision, combination or merger or sale of assets transaction provided for 
elsewhere in this Section 3) provision shall be made so that the holders of 
the Series A Preferred Stock and Series B Preferred Stock shall thereafter be 
entitled to receive upon conversion of the Series A Preferred Stock and 
Series B Preferred Stock the number of shares of stock or other securities or 
property of the Company or otherwise, to which a holder of Common Stock 
deliverable upon conversion would have been entitled on such 
recapitalization.  In any such case, appropriate adjustment shall be made in 
the application of the provisions of this Section 3 with respect to the 
rights of the holders of the Series A Preferred Stock and Series B Preferred 
Stock after the recapitalization to the end that the provisions of this 
Section 3 (including adjustment of the Conversion Price then in effect and 
the number of shares purchasable upon conversion of the Series A Preferred 
Stock and Series B Preferred Stock) shall be applicable after that event as 
nearly equivalent as may be practicable.

                   (e)  NO IMPAIRMENT.  This corporation will not, by 
amendment of its Certificate of Incorporation or through any reorganization, 
recapitalization, transfer of assets, consolidation, merger, dissolution, 
issue or sale of securities or any other voluntary action, avoid or seek to 
avoid the observance or performance of any of the terms to be observed or 
performed hereunder by this corporation, but will at all times in good faith 
assist in the carrying out of all the provisions of this Section 3 and in the 
taking of all such action as may be necessary or appropriate in order to 
protect the Conversion Rights of the holders of the Series A Preferred Stock 
and Series B Preferred Stock against impairment.

                                     -8-

<PAGE>

                   (f)  NO FRACTIONAL SHARES AND CERTIFICATE AS TO 
ADJUSTMENTS.

                        i)   No fractional shares shall be issued upon 
conversion of the Series A Preferred Stock and Series B Preferred Stock, and 
the number of shares of Common Stock to be issued shall be rounded to the 
nearest whole share.  Whether or not fractional shares are issuable upon such 
conversion shall be determined on the basis of the total number of shares of 
Series A Preferred Stock and Series B Preferred Stock the holder is at the 
time converting into Common Stock and the number of shares of Common Stock 
issuable upon such aggregate conversion.

                        ii)  Upon the occurrence of each adjustment or 
readjustment of the Conversion Price of Series A Preferred Stock and Series B 
Preferred Stock pursuant to this Section 3, this corporation, at its expense, 
shall promptly compute such adjustment or readjustment in accordance with the 
terms hereof and prepare and furnish to each holder of Series A Preferred 
Stock and Series B Preferred Stock a certificate setting forth such 
adjustment or readjustment and showing in detail the facts upon which such 
adjustment or readjustment is based.  This corporation shall, upon the 
written request at any time of any holder of Series A Preferred Stock or 
Series B Preferred Stock, furnish or cause to be furnished to such holder a 
like certificate setting forth (A) such adjustment and readjustment, (B) the 
Conversion Price at the time in effect, and (C) the number of shares of 
Common Stock and the amount, if any, of other property which at the time 
would be received upon the conversion of a share of Series A Preferred Stock 
or Series B Preferred Stock.

                   (g)  NOTICES OF RECORD DATE.  In the event of any taking 
by this corporation of a record of the holders of any class of securities for 
the purpose of determining the holders thereof who are entitled to receive 
any dividend (other than a cash dividend) or other distribution, any right to 
subscribe for, purchase or otherwise acquire any shares of stock of any class 
or any other securities or property, or to receive any other right, this 
corporation shall mail to each holder of Series A Preferred Stock and Series 
B Preferred Stock, at least 20 days prior to the date specified therein, a 
notice specifying the date on which any such record is to be taken for the 
purpose of such dividend, distribution or right, and the amount and character 
of such dividend, distribution or right.

                   (h)  RESERVATION OF STOCK ISSUABLE UPON CONVERSION.  This 
corporation shall at all times reserve and keep available out of its 
authorized but unissued shares of Common Stock solely for the purpose of 
effecting the conversion of the shares of the Series A Preferred Stock and 
Series B Preferred Stock such number of its shares of Common Stock as shall 
from time to time be sufficient to effect the conversion of all outstanding 
shares of the Series A Preferred Stock and Series B Preferred Stock; and if 
at any time the number of authorized but unissued shares of Common Stock 
shall not be sufficient to effect the conversion of all then outstanding 
shares of the Series A Preferred Stock and Series B Preferred Stock, in 
addition to such other remedies as shall be available to the holder of such 
Preferred Stock, this corporation will take such corporate action as may, in 
the opinion of its counsel, be necessary to increase its authorized but 
unissued shares of Common Stock to such number of shares as shall be 
sufficient for such purposes.

                                     -9-

<PAGE>

                   (i)  NOTICES.  Any notice required by the provisions of 
this Section 4 to be given to the holders of shares of Series A Preferred 
Stock or Series B Preferred Stock shall be deemed given if deposited in the 
United States mail, postage prepaid, and addressed to each holder of record 
at his address appearing on the books of this corporation.

              4.   VOTING RIGHTS.

                   (a)  GENERAL VOTING RIGHTS.  Except as set forth in 
subsection 4(b) below, the holder of each share of Series A Preferred Stock 
and the holder of each share of Series B Preferred Stock shall have the right 
to one vote for each share of Common Stock into which such share of Series A 
Preferred Stock and/or such share of Series B Preferred Stock could then be 
converted (with any fractional share determined on an aggregate conversion 
basis being rounded to the nearest whole share), and with respect to such 
vote, each such holder shall have full voting rights and powers equal to the 
voting rights and powers of the holders of Common Stock, and shall be 
entitled, notwithstanding any provision hereof, to notice of any 
stockholders' meeting in accordance with the by-laws of this corporation, and 
shall be entitled to vote, together with holders of Common Stock, with 
respect to any question upon which holders of Common Stock have the right to 
vote.

                   (b)  ELECTION OF DIRECTORS.  Notwithstanding the 
provisions of subsection 4(a) above, (i) so long as any shares of Series A 
Preferred Stock are outstanding, the holders of the then outstanding shares 
of Series A Preferred Stock, by a majority vote voting as a separate class, 
shall be entitled to elect four (4) directors of the corporation (the "Series 
A Directors") and the holders of Common Stock and Series A Preferred Stock, 
by a majority vote voting as a single class, shall be entitled to elect one 
(1) director of the corporation (the "Common/Series A Director"); (ii) so 
long as any shares of Series B Preferred are outstanding, the holders of the 
then outstanding shares of Series B Preferred Stock, by a majority vote 
voting as a separate class, shall be entitled to elect one (1) director of 
the corporation (the "Series B Director"); and (iii) all remaining directors 
shall be elected by the holders of the Preferred Stock and the holders of 
Common Stock, by a majority vote voting as provided in paragraph 4(a) above.  
At any meeting held for the purpose of electing or nominating directors, the 
presence in person or by proxy of the holders of a majority of the Series A 
Preferred Stock then outstanding shall constitute a quorum of the Series A 
Preferred Stock for the election or nomination of the Series A Directors, the 
presence in person or by proxy of the holders of a majority of the shares of 
Series B Preferred Stock then outstanding, shall constitute a quorum of the 
Series B Preferred Stock for the election or nomination of the Series B 
Director, the presence in person or by proxy of the holders of a majority of 
the Common Stock and Series A Preferred Stock, on an as-converted basis, then 
outstanding shall constitute a quorum of the Common Stock and Series A 
Preferred Stock for the election or nomination of the Common/Series A 
Director, and the presence in person or by proxy of the holders of a majority 
of the Preferred Stock and Common Stock, on an as-converted basis, then 
outstanding shall constitute a quorum of the Preferred Stock and Common Stock 
for the election or nomination of all remaining directors.  A vacancy in any 
directorship elected solely by the holders of Series A Preferred Stock shall 
be filled only by vote of the holders of Series A Preferred Stock, a vacancy 
in the directorship elected solely by the holders of the Series B Preferred 
Stock shall be filled only by vote of the Series B Preferred Stock, a vacancy 
in the directorship elected by the holders of the Common Stock and Series A 
Preferred Stock shall be filled only by vote of the Common Stock and Series A 
Preferred Stock,
                                      -10-

<PAGE>

voting together as provided above, and a vacancy in any directorship elected 
by the holders of Preferred Stock and Common Stock shall be filled only by 
the vote of the holders of Preferred Stock and Common Stock voting as 
provided in paragraph 4(a) above.  Any director elected by the holders of 
Series A Preferred Stock may be removed during such director's term of 
office, either for or without cause, by and only by the affirmative vote of 
the holders of a majority of the outstanding shares of Series A Preferred 
Stock, any director elected by the holders of Series B Preferred Stock may be

corporation to provide indemnification) existing at the time of, or increase

person) with respect to any acts or omissions of such director, officer or 
agent (or other person) occurring prior to, such repeal or modification.

                          CERTIFICATE OF AMENDMENT OF

     Rhythms NetConnections Inc., a corporation organized and existing under 
and by virtue of the General Corporation Law of the State of Delaware (the 
"Corporation"), certifies as follows:

permitted by Section 103 of the General Corporation Law of the State of 
Delaware.

     2.   The resolutions set forth in the Amendment inconsistently stated

Amendment shall read in its entirety as follows:

          Stock and thereafter, to increase the authorized 
          number of shares of Common Stock of the Corporation, 
          the officers of the Corporation are hereby authorized 
          and directed to execute and file a Certificate of 
          Amendment to the Restated Certificate of

          Forty-Three (66,708,243) shares shall be Common
          Stock, $0.001 par value per share and Sixteen
          Million Nine Hundred Forty-Four Thousand Nine
          Hundred Forty-Three (16,944,943) shares shall be

Suite 200, San Diego, California 92123 (GTE and ACI being referred to
collectively as the "Parties" and individually as a "Party").  This Agreement
covers services in the state of California 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 and mutually agreed
upon interconnection points; and

WHEREAS, the Parties wish to enter into an agreement to interconnect their
respective telecommunications networks on terms that are fair and equitable to
both Parties; and

WHEREAS, Section 251 of the Telecommunications Act of 1996 (the "Act") imposes
specific obligations on LECs with respect to the interconnection of their
networks, resale of their telecommunications services, access to their poles,
ducts, conduits and rights-of-way and, in certain cases, the offering of certain
unbundled network elements and physical collocation of equipment in LEC
premises; and

WHEREAS, both Parties agree that: rates in this Agreement are those that
resulted from the arbitration of the MCI agreement, which is currently on
appeal; both Parties wish to avoid the expense and delay of arbitrating rates in
this Agreement; ACI is putting itself in the legal position of MCI with respect
to those rates in this Agreement that are drawn from the MCI arbitration; GTE is
fully preserving its legal positions, rights and remedies with respect to those
rates, and; the Parties will conform the rates in this Agreement to the results
of that appeal and any subsequent proceedings.

NOW, THEREFORE, in consideration of the mutual provisions contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, GTE and ACI hereby covenant and agree as follows:

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 end user customers, and reciprocal access to poles, ducts, 
conduits and rights-of-way.  This Agreement also governs the purchase by ACI 
of certain unbundled network elements from GTE, and the terms and conditions 
of the collocation of certain equipment of ACI in the premises of GTE. This 
Agreement will be submitted to the California Public Utilities Commission 
(the "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. ACI 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 
contained herein are unlawful, illegal and improper.

The services and facilities to be provided to ACI by GTE in satisfaction of 
this Agreement may be provided pursuant to GTE tariffs and then current 
practices. As to services and facilities, the terms of which are governed by 
tariff pursuant to the terms of this Agreement, then modification to the 
tariff terms will be deemed to be applicable to any rates, terms, and 
conditions of this Agreement, unless otherwise specified herein in accordance 
with Article III, Section 40. Should services and facilities, the terms of 
which are defined in this Agreement (and not governed by tariff pursuant to 
terms of this Agreement), be modified by an immediately effective Order, 
including any modifications resulting from other Commission proceedings, 
federal court review or other judicial action, the modifications will be 
deemed to be applicable to any rates, terms, and conditions of this 
Agreement, unless otherwise specified herein in accordance with Article III, 
Section 40.

     breach. Nothing in this section shall be construed to divest the
     Commission or the FCC of any jurisdiction they otherwise have over
     matters of public policy or interpretation of, and compliance with, state
     or federal law, and either Party may seek redress from the Commission or
     FCC to resolve such matters, as provided by state or federal law.

     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.

     proprietary or creative right, or any other injury to any person or

     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

     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

     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 the opinion of
     either Party, in a material change to this Agreement.  If a material
     change as described in this paragraph occurs as a result of 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.

     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 as GTE requires 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

       any waste materials such as petroleum contaminated water, sewage or
       manhole sediment.  Notwithstanding Sections 24 and 44.9 hereunder, the
       cost causer (requiring access) shall indemnify the other Party hereunder.

44.6   ACI should obtain and use its own environmental permits, if necessary. 
       If GTE's permit or EPA identification number must be used, ACI must
       comply with all of GTE's environmental processes including environmental
       "best management practices (BMP)" and/or selection of disposition vendors
       and disposal sites.

44.7   ACI 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 ACI 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 ACI
       must develop a cost sharing procedure.

44.9   Notwithstanding Section 23, with respect to environmental responsibility
       under this Section 44, GTE and ACI 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 ACI 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, the requesting Party may elect to
       enter into Dispute Resolution pursuant to Article III, Section 14 or the
       Parties may agree on an interim price shall be set for such item that is
       equal to the price for the nearest analogous item for which


                                      III-17
<PAGE>

       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 ACI to GTE, and any
       overpayment shall be refunded by GTE to ACI, 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
       "MCI Terms") were taken from the GTE/MCI Interconnection, Resale and
       Unbundling Agreement (the MCI Agreement) approved by the Commission in
       Application No. 96-09-012.  The rates, terms and conditions not included
       in this Agreement but referenced in Attachment 46B (the "GTE Terms") were
       excluded from the MCI Agreement by the Commission in Application No.
       96-09-012. GTE and ACI agree that if the "MCI 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 "MCI Terms" or, as appropriate, the substitution of
       "GTE Terms" for all stayed and enjoined "MCI Terms", and such amendments
       shall be effective retroactive to the Effective Date of this Agreement.

       GTE and ACI further agree that the terms and conditions of this Section
       46 reflect certain requirements of the FCC's First Report and Order in CC
       Docket No. 96-98.  The terms and conditions of this Section 46 shall be
       subject to any and all actions by any court or other governmental
       authority that invalidate, stay, vacate or otherwise modify 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 Section 46
       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 in this Section 46, 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 "MCI Terms" are affected by such
       Action and they cannot be consistently applied therewith, the "GTE Terms"
       shall apply.  ACI 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 "MCI Terms" are
       further subject to amendment, retroactive to the Effective Date of the
       Agreement, to


                                      III-18
<PAGE>

       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.
     
       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, then the Parties agree that they
       will reopen negotiations within ten (10) days after receipt of the final
       decision making such deletion or modification in order to negotiate
       replacement provisions which comply with such Commission or court
       requirements and which provide substantially the same protections to the
       Parties as this Section 46. If the Parties cannot reach agreement as to
       replacement provisions for this Section 46 within twenty (20) calendar  
       days of the initiation of negotiations, the Parties agree that this
       entire Section 46 is void. In such event, within twenty five (25) days
       following the close of the 20 day negotiation period, either Party may
       initiate the Dispute Resolution Process provided in Article III, Section
       14.1 herein regarding issues in dispute for such replacement provisions.

                                      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 ACI for resale and unbundled network elements provided by GTE
       to ACI, 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 "ACI" 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 ACI's customers or
       any other Third Party.  Liability of GTE to ACI 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 ACI and shall not
       be liable for the integration of components combined by ACI.

2.2    ACI TARIFFS OR CONTRACTS. GTE shall not be liable to ACI'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 ACI of the
       possibility of such damages.  Nothing in this Agreement shall be deemed
       to create a Third Party beneficiary relationship with ACI's end users. To
       the extent practicable, ACI will include a provision in its tariffs,
       price lists, or contracts for services provided to its end users so
       limiting the liability of LECs, such as GTE, that provide underlying
       services, facilities, or network elements.

2.3    NO LIABILITY FOR ERRORS.  GTE is not liable for mistakes that appear in
       GTE's listings, 911 and other information databases, or for incorrect
       referrals of end users to ACI for any ongoing ACI service, sales or
       repair inquiries, and with respect to such mistakes or incorrect
       referrals, ACI 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 third parties, including ACI's end users or employees.  For
       purposes of this Section 2.3, mistakes and incorrect referrals shall not
       include matters arising out of the gross negligence, as evidenced by a


                                       IV-1
<PAGE>

       pattern of excessive mistakes or errors, or  willful misconduct of GTE or
       its employees or agents.

3.     UNAUTHORIZED CHANGES.

3.1    PROCEDURES.  If ACI 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 ACI to
       provide local exchange services to the end user, ACI must provide GTE
       with written documentation of authorization from that end user within
       thirty (30) Business Days of notification  by GTE.  If ACI cannot provide
       written documentation of authorization within such time frame, ACI 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 ACI was made; and

       (b)  provide any end user information and billing records ACI 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 the ACI 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.  ACI 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
       ACI fails to pay when due any and all charges billed to ACI 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 ACI may withhold payment, GTE shall
       notify ACI in writing that it must pay all Unpaid Charges to GTE within
       seven (7) Business Days.  If ACI 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
       ACI and GTE are unable, within thirty (30) Business Days thereafter, to
       resolve issues related to the disputed charges, then either ACI or GTE
       may file a request for arbitration under Article III of this Agreement to
       resolve those issues.  Upon


                                       IV-2
<PAGE>

       resolution of any dispute hereunder, if ACI owes payment it shall make
       such payment to GTE with any late payment charge under Article III,
       Section 7.2, from the original payment due date.  If ACI 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 ACI upon failure to pay undisputed charges as provided in this
       Section 4, and shall have no liability to ACI or ACI'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 ACI or
       its end users for any purpose in violation of law. GTE, shall not be
       responsible to ensure that ACI 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 ACI or
       disconnect particular services, facilities or unbundled elements provided
       under this Agreement to ACI or, as appropriate, ACI'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 ACI, 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 ACI 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 calling station "hangs up," thereby releasing the 
       network connection.  If the called station "hangs up" but the calling 
       station does not, chargeable time ends when the network connection is 
       released by automatic timing equipment in the network 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 for many of these functions are 
       described in APPENDIX H.  All costs and expenses for any new or 
       modified electronic interfaces ACI requires that


                                       IV-3
<PAGE>

       GTE determines are technically feasible and GTE agrees to develop will 
       be paid by ACI pursuant to APPENDIX H.  The schedule for 
       implementation of any new or modified electronic interfaces will be 
       developed by GTE according to industry standards and will be based 
       upon the amount of work needed to design, test and implement the new 
       or modified interface.

8.     CUSTOMER CONTACTS.  Except as otherwise provided in this Agreement or 
       as agreed to in a separate writing by ACI, ACI shall provide the 
       exclusive interface with ACI's end user customers in connection with 
       the marketing or offering of ACI 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 
       ACI's end users, such personnel shall not identify themselves as 
       representing GTE.  All forms, business cards or other business 
       materials furnished by GTE to ACI end users shall bear no corporate 
       name, logo, trademark or trade name other than ACI's.  In no event 
       shall GTE personnel acting on behalf of ACI pursuant to this Agreement 
       provide information to ACI end users about GTE products or services.

9.     LETTER OF AUTHORIZATION.

       9.1  GTE will not release the Customer Service Record (CSR) containing
            Customer Priority Network Information (CPNI) to ACI on GTE end
            user customer accounts unless ACI first provides to GTE a written
            Letter of Authorization (LOA), signed by the end user customer,
            authorizing the release of such information to ACI or if state or
            federal law provides otherwise, in accordance with such law.
     
       9.2  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 ACI.  Such LOA may be a blanket LOA or such
            other form as agreed upon between GTE and ACI.

                                      ARTICLE V
               INTERCONNECTION AND TRANSPORT AND TERMINATION OF TRAFFIC


1.     SERVICES COVERED BY THIS ARTICLE.

1.1    TYPES OF SERVICES.  This Article governs the provision of internetwork 
       facilities (i.e., physical interconnection services and facilities), 
       meet point billing by GTE to ACI or by ACI 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 ACI. The services and facilities described in this Article shall 
       be referred to in this Article V as the "Services."

1.2    SERVICE LOCATIONS FOR INTERCONNECTION SERVICES AND FACILITIES.  
       APPENDIX A, Service Matrix, attached to this Agreement and made a part 
       hereof, sets forth the Services and each location in the State where a 
       Service shall be provided (the "Service Locations") and the 
       Interconnection Point ("IP") for such Services.

1.3    ADDITIONAL SERVICES OR SERVICE LOCATIONS.  If, during the term of this 
       Agreement,  the parties determine that additional services are needed 
       in the State, or existing Services will be offered in new locations in 
       the State, the Parties shall execute an amendment to this Agreement 
       substantially in the form of APPENDIX B attached to this Agreement and 
       made a part hereof, incorporating the additional locations and/or any 
       additional terms necessary for the additional services.  Upon the 
       effective date of the amendment, and continuing through the remaining 
       term of this Agreement, the new services shall be deemed part of the 
       Services provided pursuant to this Article and/or the new locations 
       shall be deemed part of the Service Locations.

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.  ACI'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.  ACI is required to order trunks 
       pursuant to Section 4.3.3 of this Article.  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


                                       V-1
<PAGE>

       the appropriate compensation arrangement and may be handled as a 
       post-billing adjustment to bills rendered.  Additional matters 
       relating to billing are included in APPENDIX H attached to this 
       Agreement and made a part hereof.

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 herein.  To this end, the Parties agree that there will 
       be interoperability between their networks.  The Parties agree to 
       exchange traffic asociated with Third-Party LECs, CLECs and Wireless 
       Service Providers pursuant to the compensation arrangement specified 
       in Section 3.3 herein.  Only traffic originated by or terminating to 
       the Parties' end user customers 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 in accordance with Section 3.2.2 of
              this Article. The Parties will develop an initial factor
              representative of the share  of traffic to be exempt from local
              compensation. This factor will be updated quarterly in like manner
              or as the Parties otherwise agree.  Once the traffic that is
              exempt from local compensation can be measured, the actual exempt
              traffic will be used rather than the above factor.  Charges for
              the transport and termination of intraLATA toll and interexchange
              traffic shall be in accordance with the Parties' respective
              intrastate or interstate access tariffs, as appropriate.

       3.2.2  BILL-AND-KEEP.  The Parties shall assume that Local Traffic is
              roughly balanced between the parties unless traffic studies
              indicate otherwise.  Accordingly, the Parties agree to use a Bill-
              and-Keep Arrangement with respect to termination of Local Traffic
              only.  Either Party may request that a traffic study be performed
              no more frequently than once a quarter.  Should such traffic study
              indicate, 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 will commence pursuant to the rates set forth in
              APPENDIX C of this Agreement and following such notice it shall
              begin and continue for the duration of the Term of this Agreement
              unless otherwise agreed.  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,


                                       V-2

              including but not limited to internetwork 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.

       3.2.3  SHARING OF ACCESS CHARGES ON CALLS TO PORTED NUMBERS.  Until
              permanent number portability is implemented, the Parties agree
              that switched access termination to a ported number will be billed
              by the party providing interim number portability and that the
              party billing the switched access will share the switched access
              revenue with the other party.  After permanent number portability
              is implemented, the Parties agree to renegotiate sharing of access
              charges to ported numbers in accordance with permanent number
              portability requirements.  In lieu of actual measurements of
              minutes and/exchange of billing records for this traffic the
              Parties agree that the Party providing the ported number will pay
              the other Party the rate per line/per month as specified in
              APPENDIX D.

              (a)  The number of lines/talk paths per ported number that are
                   subject to compensation will be determined at the time the
                   end user customer's local service is changed from one
                   party to the other.  The number of lines per number
                   eligible for the shared revenue arrangement described in
                   this section will be limited to the number of lines in
                   service on the date of conversion plus a 10% growth
                   margin.  After conversion the number of lines per number
                   available for compensation can only be increased by mutual
                   consent of the parties.

              (b)  The Parties agree that the compensation rate in paragraph
                   3.2.3 may change as a result of changes in access rates,
                   traffic volume or for other reasons and agree to
                   renegotiate the rate if a significant event occurs.  At a
                   minimum, the parties agree to reevaluate the rate on an
                   annual basis.

              (c)  The Parties agree that terminating switched access calls
                   ported via interim number portability may appear to the
                   receiving party to be a local call and that the
                   implementation of reciprocal compensation for terminating
                   local calls may result in overcompensation for ported
                   switched access calls.  Therefore, the Parties agree to
                   renegotiate the terminating shared access compensation
                   rate if reciprocal compensation for local calls is
                   implemented.


                                       V-3

3.3    TANDEM SWITCHING TRAFFIC.  The Parties will provide tandem switching 
       for traffic between the Parties' end offices subtending each other's 
       access tandem, as well as for traffic between either Party's end users 
       and any Third Party which is interconnected to the other Party's 
       access tandems as follows:

       3.3.1  The originating Party will compensate the tandem Party for each
              minute of originated tandem switched traffic which terminates to
              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 which terminates the call.

       3.3.3  The Parties agree to enter into their own agreements with third-
              party providers.  In the event that ACI sends traffic through 
              GTE's network to a third-party provider with whom ACI does not
              have a traffic interexchange agreement, then ACI agrees to
              indemnify GTE for any termination charges rendered by a third-
              party provider 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 
       originating on each other's network at and after such time as either 
       (i) ACI 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 
       support the recognition of multiple tandem switching events.

4.     DIRECT NETWORK INTERCONNECTION.

4.1    NETWORK INTERCONNECTION ARCHITECTURE.  ACI may interconnect with GTE 
       at any of the minimum technically feasible points required by the FCC. 
       Interconnection at additional points will be reviewed on an individual 
       case basis.  Where the Parties mutually agree following a Bona Fide 
       Request to directly interconnect their respective networks, 
       interconnection will be as specified in the following subsections.  
       The "IPs" shall be set forth in APPENDIX A attached to this Agreement 
       and made a part hereof.  Based on the configuration, the installation 
       timeline will vary considerably, however, GTE will work with ACI in 
       all circumstances to install "IPs" within 120 calendar days absent 
       extenuating circumstances.  Internetwork connection and protocol must 
       be based on industry standards developed consistent with Section 256 
       of the Telecommunications Act of 1996.


                                       V-4

       4.1.1  Subject to mutual agreement, the Parties may use the following
              types of network facility interconnection for the purpose of
              exchanging traffic, using such interface media as are (i)
              appropriate to support the type of interconnection requested and
              (ii) available at the facility at which interconnection is
              requested.  For each "IP" set forth in APPENDIX A, the Parties
              shall specify the type of interconnection used at that "IP."

              (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
                   GTE's applicable tariffs.

              (c)  A Special Access 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.

       4.1.3  The Parties will mutually designate at least one POI on GTE's
              network within each GTE local calling area for the routing of
              Local Traffic.  Recording and billing of traffic routed over these
              facilities shall be as provided in Section 3.4 of this Article.

4.2    COMPENSATION.  The Parties agree to the following compensation for 
       internetwork 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. 
              ACI will charge flat rated transport to GTE for ACI facilities
              used by GTE at their tariffed rates or as mutually agreed, not to
              exceed GTE rates.  ACI will apply charges based on the lesser of;
              (i) the airline mileage


                                       V-5
<PAGE>

              from the "IP" to the ACI 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.  ACI will charge GTE flat rated
              transport at their tariffed rates or as mutually agreed, not to
              exceed GTE rates, to reflect the proportionate share of the
              facility that is used for transport of traffic originated by GTE. 
              ACI will apply charges based on the lesser of; (i) the airline
              mileage from the "IP" to the ACI switch; or (ii) two (2) times the
              airline mileage from the GTE switch to the serving area boundary.

       4.2.3  Special Access:  GTE will charge special 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 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.

       4.3.2  ACI shall make available to GTE trunks over which GTE shall
              terminate to end users of ACI-provided Exchange Services, Local
              Traffic and intraLATA toll or optional EAS traffic originated from
              end users of GTE-provided Exchange Service.

       4.3.3  ACI and GTE shall, where applicable, make reciprocally available,
              by mutual agreement, the required trunk groups to handle different
              traffic types.  ACI and GTE will support the provisioning of trunk
              groups that carry combined or separate Local Traffic and intraLATA
              toll and optional EAS traffic.  GTE requires separate trunk groups
              from ACI to originate and terminate interLATA calls and to provide


                                       V-6
<PAGE>

              Switched Access Service to IXCs.  To the extent ACI desires to
              have any Interexchange Carriers (IC) originate or terminate
              traffic to ACI, ACI will arrange for such IC to issue an ASR to
              GTE instructing GTE to route such traffic over the appropriate IC
              trunk group.  Until GTE receives and processes such ASR, the
              traffic will not be routed.

              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
                       access tandem for those publicly-dialable NXX Codes
                       served by end offices that directly subtend the access
                       tandem or to those wireless service providers that
                       directly subtend the access tandem.

              4.3.3.3  Neither party shall route Switched Access Service
                       traffic over local interconnection trunks, or local
                       traffic over Switched Access Service trunks.

       4.3.4  ACI 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.

       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 to an
              objective P.01 grade of service.

       4.3.6  ACI 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.

       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.


                                       V-7
<PAGE>

4.4    NETWORK REDESIGNS INITIATED BY GTE.  GTE will not charge ACI when GTE 
       initiates its own network redesigns/reconfigurations.

4.5    INTERCONNECTION CALLING AND CALLED SCOPES FOR THE ACCESS TANDEM 
       INTERCONNECTION AND THE END OFFICE INTERCONNECTION.

       4.5.1  GTE Access Tandem Interconnection calling scope (originating and
              terminating) is to those GTE end offices which subtend the GTE
              access tandem to which the connection is made except as provided
              for in Section 3.3 herein.

       4.5.2  GTE End Office Interconnection calling scope (originating and
              terminating) is only to the end office to which the connection is
              made.

5.     INDIRECT NETWORK INTERCONNECTION.  Neither Party shall deliver traffic 
       destined to terminate at the other Party's end office via another 
       LEC's end office.  In addition, neither Party shall deliver traffic 
       destined to terminate at an end office subtending the other Party's 
       access tandem via another LEC's access tandem until such time as 
       compensation arrangements have been established in accordance with 
       Sections 3.1 and 3.4 herein.

6.     NUMBER RESOURCES.

6.1    NUMBER ASSIGNMENT.  Nothing in this Agreement shall be construed to, 
       in any manner, limit or otherwise adversely impact ACI'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 ACI 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 ACI.  The 
       Parties agree that disputes arising from numbering assignment shall be 
       arbitrated by the NANP Number Plan Administrator.  ACI 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 GTE to appropriately apply its toll tariff to its end 
       user customers, ACI shall adopt the Rate Center areas and Rate Center 
       points that the Commission has approved for the incumbent LEC and 
       shall assign whole NPA-NXX codes to each Rate Center.


                                       V-8
<PAGE>

6.3    ROUTING POINTS.  ACI will also designate a Routing Point for each 
       assigned NXX code.  ACI may designate one location within each Rate 
       Center as a Routing Point for the NPA-NXX associated with that Rate 
       Center; alternatively ACI 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 ACI 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 competitively neutral 
       manner, and process requests for NXX codes in a timely manner and in 
       accord with industry standards.  The Parties shall protect ACI 
       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    INTERIM NUMBER PORTABILITY (INP).  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 without changing their telephone number.  The Parties shall 
       provide service provider number portability to each other using remote 
       call forwarding ("RCF") and/or direct inward dialing (DID).  The 
       requesting Party will provide "forward to" telephone number that is 
       within the same wire center.  The GTE rates for INP service using RCF 
       are set out in Appendix D attached to this Agreement and made a part 
       hereof. ACI shall provide INP to GTE at the rates specified for ACI in 
       Appendix D.

       If a Party wishes to use Direct Inward Dialing (DID) to provide INP to 
       its end users, dedicated truck group is required between the GTE end 
       office where the DID numbers are served into the CLEC switch.  If 
       there are no existing facilities between GTE and the CLEC, the 
       dedicated facilities and transport trunks will be provisioned as 
       switched access or unbundled service using the Access Service Request 
       (ASR) provisioning process.  The requesting Party will reroute the DID 
       numbers to the pre-positioned trunk group using an LSR.  CLEC may 
       activate purchase DID trunk service from GTE using only the LSR at the


                                       V-9
<PAGE>

       Wholesale rates set out in Appendix E attached to this Agreement and 
       made a part hereof.

7.2    LOCAL NUMBER PORTABILITY (LNP).  The Parties agree that they shall 
       develop and deploy number portability in accordance to with the Act, 
       such binding FCC and state mandates, and industry standards, as may be 
       applicable.  Upon implementation of LNP, the Parties agree to 
       transition all INP customers and their services to LNP methods within 
       a mutually agreed upon time frame and to discontinue further use of 
       interim methods of number portability.

8.     MEET-POINT BILLING.

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 access 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
              herein and as described in Section 3.2.3 for Interim Portability.

       8.1.2  Except in instances of capacity limitations, GTE shall permit and
              enable ACI to sub-tend the GTE access tandem(s) nearest to the ACI
              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, ACI 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  ACI 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.


                                      V-10
<PAGE>

       8.1.6  As detailed in the MECAB document, ACI 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 ACI 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  ACI 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    COMPENSATION.

       8.2.1  Initially, billing to Access Service customers for the Switched
              Access Services jointly provided by ACI 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, ACI 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 ACI and GTE via the
              MPB arrangement:  single-bill/single tariff method, single-bill/
              multiple tariff method, or to continue the multiple-bill method.
              Should ACI prefer to change among these billing methods, ACI shall
              notify GTE 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 GTE mutually agrees, the change will be
              made.

9.     COMMON CHANNEL SIGNALING.

9.1    SERVICE DESCRIPTION.  The Parties will provide Common Channel 
       Signaling ("CCS") to one another via Signaling System 7 ("SS7") 
       network interconnection, where and as available, in the manner 
       specified in FCC Order 95-187, in conjunction with all traffic 
       exchange trunk groups.  SS7 signaling and transport services shall be 
       provided by GTE in accordance with the terms and conditions of this 
       Section 9 of this Article and APPENDIX I attached to this Agreement 
       and made a part hereof.  The Parties will cooperate on the exchange of 
       all appropriate SS7 messages for local and intraLATA call set-up 
       signaling, including ISUP and Transaction Capabilities Application 
       Part ("TCAP") messages to facilitate full interoperability of all 
       CLASS Features and functions between their respective networks.  Any 
       other SS7 message services


                                      V-11
<PAGE>

       to be provided using TCAP messages (such as data base queries) will be
       jointly negotiated and agreed upon.

9.2    SIGNALING PARAMETERS.  All SS7 signaling parameters will be provided 
       in conjunction with traffic exchange trunk groups, where and as 
       available. These parameters include Automatic Number Identification 
       ("ANI"), Calling Party Number ("CPN"), Privacy Indicator, calling 
       party category information, originating line information, charge 
       number, etc.  Also included are all parameters relating to network 
       signaling information, such as Carrier Information Parameter ("CIP"), 
       wherever such information is needed for call routing or billing.  GTE 
       will provide SS7 via GR-394-SS7 and/or GR-317-SS7 format(s).

9.3    PRIVACY INDICATORS.  Each Party will honor all privacy indicators as
       required under applicable law.

9.4    CONNECTION THROUGH STP.  ACI must interconnect with the GTE STP(s) 
       serving the LATA in which the traffic exchange trunk groups are 
       interconnected.  Additionally, all interconnection to GTE's 800/888 
       database and GTE's LIDB shall, consistent with this section and 
       APPENDIX I attached hereto, take place only through appropriate STP 
       pairs.

9.5    THIRD PARTY SIGNALING PROVIDERS.  ACI may choose a third-party SS7 
       signaling provider to transport messages to and from the GTE SS7 
       network. In that event, that third-party provider must present a 
       letter of agency to GTE, prior to the testing of the interconnection, 
       authorizing the Third Party to act on behalf of ACI in transporting 
       SS7 messages to and from GTE.  The third-party provider must 
       interconnect with the GTE STP(s) serving the LATA in which the traffic 
       exchange trunk groups are interconnected.

9.6    MULTI-FREQUENCY SIGNALING.  In the case where CCS is not available, in 
       band Multi-Frequency ("MF"), wink start, E & M channel associated 
       signaling with ANI will be provided by the Parties.  Network signaling 
       information, such as CIC/OZZ, will be provided wherever such 
       information is needed for call routing or billing.

10.    SERVICE QUALITY AND PERFORMANCE.  Each Party shall provide Services 
       under this Article to the other Party that are equal in quality to 
       that the Party provides to itself, its Affiliates or any other entity. 
        "Equal in quality" shall mean that the Service will meet the same 
       technical criteria and performance standards that the providing Party 
       uses within its own network for the same Service at the same location 
       under the same terms and conditions.

11  .  NETWORK OUTAGES.  GTE shall work with ACI to establish reciprocal 
       responsibilities for managing network outages and reporting.  Each 
       party shall


                                      V-12
<PAGE>

       be responsible for network outage as a result of termination of its
       equipment in GTE wire center or access tandem.  ACI shall be responsible
       for notifying GTE of significant outages which could impact or degrade
       GTE switches and services.

                             UNBUNDLED NETWORK ELEMENTS


1.     GENERAL.  The purpose of this Article VII, VII is to define the 
       unbundled network elements that may be  leased by ACI from GTE.  
       Unless otherwise specified in this Agreement, provisioning of 
       unbundled network arrangements will be governed with the GTE Customer 
       Guide for CLEC Establishment of Services - Resale and Unbundling (the 
       "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)    Dedicated Transport Elements

       (e)    Signaling Elements

     
       2.2    PRICES.  Individual unbundled network elements and prices are 
              identified on APPENDIX F attached to this Agreement and made a 
              part hereof, or under the appropriate GTE tariff as referenced 
              in this Article.  Nonrecurring charges relating to unbundled 
              elements are also listed on APPENDIX F.

              2.2.1   Compensation arrangements for exchanging traffic when 
                      ACI uses GTE provided unbundled port and local 
                      switching elements shall be as provided in APPENDIX L 
                      attached hereto.

       2.3    INTERCONNECTION TO UNBUNDLED ELEMENTS.  ACI may lease and 
              interconnect to whichever of these unbundled network elements 
              ACI chooses, and subject to technical feasibility, may combine 
              these unbundled elements with any facilities or services that 
              ACI may itself provide subject to the following:


                                    VII-1
<PAGE>

              2.3.1   Interconnection shall be achieved via physical 
                      collocation arrangements ACI shall maintain at the wire 
                      center at which the unbundled services are resident. 
                      Pursuant to Article IX, Section 2. of this Agreement, 
                      in circumstances where physical collocation cannot be 
                      accomodated at wire centers where the unbundled 
                      services are resident, alternative arrangements will be 
                      negotiated.
     
              2.3.2   Each loop or port element shall be delivered to ACI's 
                      collocation arrangement over a loop/port connector 
                      applicable to the unbundled services as listed on 
                      APPENDIX F.

              2.3.3   ACI shall combine unbundled network elements with its 
                      own facilities.  GTE has no obligation to combine any 
                      network elements for ACI; 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 ACI regarding 
                      the provisioning of such elements in accordance with 
                      that decision.  Once GTE's unbundled network elements 
                      have been connected to ACI's facilities, as described 
                      in this Agreement, ACI is not precluded from combining 
                      the unbundled elements using its own facilities, except 
                      that ACI may not combine such network elements to 
                      provide solely interexchange service or solely switched 
                      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.  
              Notwithstanding the foregoing, GTE shall not be responsible for 
              impacts on service attributes, grades of service, etc., 
              resulting from ACI's specific use of or modification to any 
              unbundled network element.  

3.     NETWORK INTERFACE DEVICE.


                                    VII-2
<PAGE>

       3.1    DIRECT CONNECTION.  ACI shall be permitted to connect its own 
              Loop directly to GTE's Network Interface Device or NID in cases 
              in which ACI uses its own facilities to provide local service 
              to an end user formerly served by GTE, as long as such direct 
              connection does not adversely affect GTE's network.  In order 
              to minimize any such adverse effects, ACI 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, ACI must make 
                      a clean cut on the GTE drop wire at the NID so that no 
                      bare wire is exposed.  ACI 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, ACI must remove the 
                      jumper wire from the distribution block (i.e. the NID) 
                      to the GTE cable termination block.  If ACI cannot gain 
                      access to the cable termination block, ACI must make a 
                      clean cut at the closest point to the cable termination 
                      block.  At ACI's request and discretion, GTE will 
                      determine the cable pair to be removed at the NID in 
                      multi-tenant locations.  ACI will compensate GTE for 
                      the trip charge necessary to identify the cable pair to 
                      be removed.

              3.1.3   GTE agrees to offer NIDs for lease to ACI but not for 
                      sale.  ACI may remove GTE identification from any NID 
                      which it connects to a ACI loop, but ACI may not place 
                      its own identification on such NID.

              3.1.4   GTE Loop elements leased by ACI will be required to 
                      terminate only on a GTE NID.  If  the CLEC leasing a 
                      GTE loop wants a CLEC NID, they will also be required 
                      to lease a GTE NID for the direct loop termination and 
                      effect a NID to NID connection.

       3.2    NID TO NID CONNECTION.  Rather than connecting its loop 
              directly to GTE's NID, ACI may also elect to install its own 
              NID and effect a NID to NID connection to gain access to the 
              end user's inside wiring.

              3.2.1   The CLEC that provides its own loop facilities may 
                      elect to move all inside wire terminated on a GTE NID 
                      to one provided by the CLEC.  In this instance, a NID 
                      to NID connection will not be required.  ACI, or the 
                      end user premise owner, can elect to leave the GTE 
                      disconnected 


                                    VII-3
<PAGE>

                      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 ACI to terminate service is the responsibility of 
              ACI.

       3.4    MAINTENANCE.  When ACI provides its own loop and connects 
              directly to GTE's NID, GTE does not have the capability to 
              perform remote maintenance.  ACI 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 ACIs option, it can make a NID to NID connection, 
              using the GTE NID only to gain access to the inside wire at the 
              customer location.

4.     LOOP ELEMENTS.

       4.1    SERVICE DESCRIPTION.  A "Loop" is an unbundled component of 
              Exchange Service.  In general, it 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.  There are six general categories of loops:

              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;

              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;

              4.2.3   "2-wire digital" loops will support industry standard 
                      specifications for digital transmission. Additional 
                      provisioning (removal of bridge taps and/or load coils) 
                      may 


                                    VII-4
<PAGE>

                      be required to conform to these industry standards. 
                      Dependent on the method of provisioning the loop, a 
                      2-wire digital loop may be configured to support 
                      service enhancing technologies such as ADSL or ISDN.

              4.2.4   "4-wire digital" loops will support industry standard 
                      specifications for digital transmission. Additional 
                      provisioning (removal of bridge taps and/or load coils) 
                      may be required to conform to these industry standards. 
                      Dependent on the method of provisioning the loop, a 
                      4-wire digital loop may be configured to support 
                      service enhancing technologies such as HDSL or ISDN.

              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, office terminating repeaters, and DSX cross 
                      connects. Prices for DS-1 grade loops are the prices 
                      set forth in the appropriate GTE intrastate 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.

       4.3    CONDITIONED LOOPS.  ACI may also require that the 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.  Digital 
              loops ordered above will be provisioned to meet industry 
              standard service levels for generally available digital 
              services, such as ISDN or ADSL, without the requirement for 
              ordering additional conditioning. ACI must indicate on the 
              order, via industry standard ordering codes, the service 
              capability requested.

       4.4    FEATURES, FUNCTIONS, ATTRIBUTES.  To the degree reasonably 
              possible, all transport-based features, functions, service 
              attributes, grades-of-service, installation, maintenance and 
              repair intervals that apply to the bundled services will apply 
              to unbundled loops.

              4.4.1   GTE will not perform routine testing of the unbundled 
                      loop for maintenance purposes.  ACI will be required to 


                                    VII-5
<PAGE>

                      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 ACI.

              4.4.2   All Loop facilities furnished by GTE on the premises of 
                      ACI's end users and up to the network interface or 
                      functional equivalent are the property of GTE. ACI is 
                      responsible for ensuring GTE has access to all such 
                      facilities for network management purposes. In the  
                      event ACI is unable to provide GTE reasonable access to 
                      such facilities, ACI acknowledges that GTE may not be 
                      able to meet its service obligations. 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   GTE will provide loop transmission characteristics to 
                      ACI end users which are equal to those provided to GTE 
                      end users.

              4.4.4   If ACI leases digital loops, pursuant to sections 4.2.3 
                      or 4.2.4 above, GTE will test the loop and provide 
                      recorded test results to ACI.  In maintenance and 
                      repair cases, if loop tests are taken, GTE will provide 
                      any recorded readings to ACI at time the trouble ticket 
                      is closed in the same manner as GTE provides to itself 
                      and its end users.

       4.5    LOOP CARRIER TECHNOLOGIES.  Where GTE utilizes integrated 
              digital loop carrier ("IDLC")(1) technology to provision the Loop 
              element, GTE cannot provide an unbundled loop. Where GTE uses 
              Universal Digital Loop Carrier "UDLC" or analog carrier to 
              provision the loop element, GTE may be able to  provide an 
              unbundled loop, however, the capabilities of the loop may be 
              limited. If ACI orders a digital loop to a location that is 
              normally served by either IDLC or UDLC, GTE will use 
              alternative facilities, if available, to provide the requested 
              loop type.

              GTE will work with ACI to develop a joint planning process to 
              allow ACI to assess the impact of GTE's use of digital loop 
              carrier technology in marketing its services that are dependent 
              on using GTE provided unbundled local loops. Such a process 
              will provide general information as to the type and relative 
              use of digital loop carrier technology in a market as well as 
              the capability to determine on a customer specific/route 
              specific basis if digital loop carrier is used to provision the 
              loop.

              4.5.1   GTE will permit ACI to collocate digital loop carriers 
                      and associated equipment in conjunction with 
                      collocation arrangements ACI maintains at a GTE wire 
                      center for the purpose of interconnecting to unbundled 
                      Loop elements.

              4.5.2   Should equipment be developed  that allows xDSL 
                      services to be provided over loops that are provisioned 
                      in any part by digital loop carrier technology and 
                      should GTE's collocation policy allow CLECs to 
                      collocate such equipment to provide xDSL services over 
                      GTE provided unbundled loops, GTE shall offer such 
                      collocation to ACI with respect to both the type of 
                      equipment ACI is permitted to collocate and the 
                      location of such collocation in compliance with the 
                      nondiscrimination requirements of the ACT.

       4.6    UNBUNDLED LOOP FACILITY QUALIFICATION.

              4.6.1   Before deploying any service enhancing copper cable 
                      technology (e.g., HDSL, ISDN, etc.) over unbundled 
                      analog voice grade loop, leased from GTE, pursuant to 
                      sections 4.2.1 and 4.2.2 above, ACI 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 ACI 
                      deployed the proposed service enhancing copper cable 
                      technology. If GTE believes that interference would 
                      occur, GTE will provide ACI with sufficient information 
                      to enable ACI to make an independent determination 
                      whether interference would occur. If, after discussion 
                      with ACI, GTE determines that there are existing copper 
                      cable loop transport technologies already deployed 
                      within the same cable sheath, or if GTE already has 
                      existing near term (within 6 months of the date of 
                      facility certification) plans to deploy copper cable 
                      loop transport technologies that would be interfered 
                      with as 


                                    VII-7
<PAGE>

                      described above, GTE will so inform ACI and ACI shall not
                      be permitted to deploy such service enhancing copper cable
                      technologies.  GTE may charge ACI the applicable 
                      engineering time and labor costs to perform the 
                      qualification.

              4.6.2   If ACI orders unbundled digital loops pursuant to 
                      Sections 4.2.3 and 4.2.4 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. As described above in Section 
                      4.6.1, GTE will determine if compatibility issues exist 
                      and, if facilities are available, will provide a loop 
                      capable of meeting the requested service capabilities.

              4.6.3   If ACI fails to notify GTE of its plans to deploy 
                      service enhancing copper cable technology over 
                      unbundled analog voice grade loops, or fails to 
                      properly order an unbundled digital loop, and obtain 
                      prior qualification from GTE of the facilities, if 
                      ACI'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, ACI will immediately 
                      remove such service enhancing copper cable technology 
                      and shall reimburse GTE for all incurred expense 
                      related to this interference. 

       4.7    COMPATIBILITY. Provided ACI has notified GTE, pursuant to 4.6. 
              preceding or via an order for digital loop services, of the 
              servicing enhancing copper cable technology deployed on an 
              unbundled loop, GTE will not deploy service enhancing 
              technology within the same cable sheath that would be 
              incompatible with ACI'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 (subloop elements). If ACI provides 
                      a good faith  request to GTE to provide subloop 
                      elements at a specific location, GTE will work 
                      cooperatively with ACI to determine if subloop elements 
                      can be provided at the specified location. If it is 
                      determined that subloop elements can be provided, the 
                      Parties will negotiate the terms and conditions for 
                      providing subloop elements.


                                    VII-8
<PAGE>

              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 ACI.  

              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 ACI.  The Parties understand 
                      that embedded loop concentrators/multiplexers are not 
                      necessarily capable of providing advanced and/or 
                      digital services.  

              4.8.4   GTE will provide loop transmission characteristics as 
                      specified in Section 4.4.3 herein.

5.     PORT AND LOCAL SWITCHING ELEMENTS.

       5.1    PORT.  Port is an unbundled component of Exchange Service that 
              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 direct inward dialing 
                      (DID) trunk side switch connection employed to provide 
                      the equivalent of 24 analog incoming trunk type 
                      Exchange Services.


                                    VII-9
<PAGE>

              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 2-wire analog and DS-1 Ports are 
              listed in APPENDIX F.  2-wire ISDN line side Ports and 4-wire 
              ISDN trunk side Ports shall be provided at a price agreed to by 
              the Parties.

       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 initially offer those features and 
              functions currently available to the particular platform used 
              (e.g., DMS, 5ESS, GTD5). Any feature or function which is not  
              offered, but the switch is capable of providing, may be 
              requested  and the Parties will mutually agree upon price, 
              terms and conditions.  ACI 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   ACI must purchase Local Switching with the line-side 
                      Port or trunk-side Port, if applicable.

       5.5    COMPLIANCE WITH SECTION 2.3.  ACI shall only order unbundled 
              elements in accordance with Section 2.3 herein and it will be 
              the responsibility of ACI 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).


                                    VII-10
<PAGE>

              5.6.2   When ACI purchases unbundled local switching, ACI 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 
                      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).  Untial 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.

              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 ACI if ACI 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  ACI 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 ACI premise ("CLEC Dedicated Transport" 
       or "CDT").  CDT remains within the exchange boundaries of the SWC, 
       while IDT traverses 


                                    VII-11
<PAGE>
 
       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 
       ACI's Customer Designated Location ("CDL").  The CDL will be the 
       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 ACI'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.  DCT 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.

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 ACI's local exchange services shall be provided in 
       accordance with the terms and conditions of APPENDIX H attached to 
       this Agreement and made a part hereof.

       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.


                                    VII-12

10.    OPERATOR SERVICES (OS) AND DIRECTORY ASSISTANCE (DA).  GTE will provide
       OS and DA to ACI 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 a CLECs own 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.  (Refer to Article VIII for 
              further details).

       10.2   When OS and/or DA is to be provided for calls that originate 
              from an unbundled Port with Local Switching, as provided 
              herein, and neither branding nor unbranding is requested, the 
              CLECs 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 with Local Switching, as provided 
              herein, 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 where Customized Routing is Currently Available. 
              Upon receipt of an order for unbranding or rebranding, GTE will 
              implement within 90 Business Days when technically capable.

       10.4   ACI will be billed charges for OS and DA and a charge for 
              unbranding or rebranding and Customized Routing as set forth in 
              Section 9.  In addition, charges specified in Section 9 will 
              apply.
 
       10.5   For those offices that ACI has requested GTE to rebrand and/or 
              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 ACI. ACI must negotiate with the third 
              party.  In these instances, ACI will need to purchase 
              customized routing to differentiate OS/DA traffic from GTE's.

11.    CUSTOMIZED ROUTING.  Where Currently Available and upon receipt of a 
       written Bona Fide request (BFR) from ACI as described in Article VIII, 
       Section ?, 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)


                                    VII-13
<PAGE>

              1+HNPA-555-1212 (intraLATA, only when intraLATA presubscription
              is not available).

       11.1   GTE will provide ACI a list of switches that can provide 
              customized routing using line class codes or similar method 
              (regardless of current capacity limitations).  ACI will return 
              a list of these switches ranked in priority order.  GTE will 
              return to ACI a schedule for customized routing in the switches 
              with existing capabilities and capacity.

       11.2   In response to the BFR from ACI, GTE will provide ACI with 
              applicable charges, and terms and conditions, for providing OS 
              and DA, branding, and customized routing.

       11.3   Subject to the above provisions, GTE will choose the method of 
              implementing customized routing of OS and DA calls.

       11.4   When GTE agrees to provide customized routing to ACI, ACI will 
              be required to establish dedicated transport in order to route 
              OS/DA traffic to the designated platform.  If unbundled 
              Dedicated Transport is used to route OS/DA traffic to the 
              designated platform, ACI must purchase a trunk side port and 
              establish a collocation arrangement in accordance with Section 
              2.3 of this Article.  The rates for these Unbundled Network 
              Elements will be billed in accordance with Appendix F.  If the 
              Dedicated Transport used to route OS/DA traffic to the 
              designated platform is ordered out of the applicable access 
              tariff, no collocation arrangement or trunk side port is 
              required.

12.    ADVANCED INTELLIGENT NETWORK ACCESS (AIN).  GTE will provide ACI 
       access to GTE AIN functionality from GTE's AIN SCP via GTE's local 
       switch or ACI's local switch.  

13.    NONDISCRIMINATION PROVISION AND SUPPORT.  GTE agrees to provide 
       unbundled network elements in a timely manner considering the need and 
       volume of requests. GTE will provide unbundled network elements in a 
       non-discriminatory manner as required by the Act and shall provide 
       power to such elements on the same basis as GTE provides to itself.

14.    PROVISIONING INTERVALS.  GTE agrees to provide unbundled network 
       elements in a timely manner considering the need and volume of 
       requests, pursuant to agreed upon service provisioning intervals. Such 
       provisioning intervals shall be provided in a nondiscriminatory manner 
       as required by the Act.

15.    DIRECTORY ASSISTANCE LISTING.  When ACI orders an unbundled port, a 
       Directory Service Request (DSR) must be submitted to have the listing 
       included in GTE's Directory Assistance database.  The applicable 
       ordering charge will be applied for processing the DSR.

               ADDITIONAL SERVICES AND COORDINATED SERVICE ARRANGEMENTS


1.   BONA FIDE REQUEST PROCESS.

1.1  INTENT.  The Bona Fide Request process may be used by ACI to request
     certain services, features, capabilities or functionality not currently
     defined  in this Agreement.

1.2  PROCESS.

  1.2.1   A Bona Fide Request shall be submitted in writing by ACI and shall
          specifically identify the need to include technical requirements,
          space requirements and/or other such specifications that clearly
          define the request.

  1.2.2   Although not expected to do so, ACI may cancel a Bona Fide Request
          in writing at any time prior to ACI 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 ACI's request. GTE
          will consider relevant portions of previous BFRs, from any carrier,
          in the evaluation of the BFR in progress to make best efforts to
          shorten response times and, to the extent possible, avoid duplicate
          work.  If extraordinary circumstances prevail, GTE will inform ACI
          as soon as it realizes that it cannot meet the ten (10) Business
          Day response due date.  ACI and GTE will then determine a mutually
          agreeable date for receipt of the request.

  1.2.5   Unless ACI 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
          ACI, in accordance with the applicable provisions of the Agreement.

  1.2.6   If at any time an agreement cannot be reached as to the terms and
          conditions or price of the request GTE agrees to meet, the dispute
          resolution procedures described in Article III hereunder may be
          used by a Party to reach a resolution.


                                     VIII-1

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 ACI.

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.  If ACI has a 911 obligation in a specific area and
     if GTE provides the  routing service for 911 traffic in that area,  ACI
     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
     ACI 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 ACI 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 ACI central office serves end users in an area served by more than one
     (1) GTE 911/E911 selective router, ACI 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

<PAGE>

4.2  TRANSPORT.  If ACI desires to obtain transport from GTE to the GTE 911
     selective routers, ACI 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 ACI'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 ACI 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 ACI 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
          ACI in accordance with the following:

  4.4.5.1 GTE and ACI shall conform to all state regulations concerning
          emergency services.

  4.4.5.2 For E911, both ACI 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.


                                     VIII-3

<PAGE>

  4.4.5.3 If legally required by the appropriate jurisdiction, GTE shall
          provide or overflow 911 traffic to be routed to GTE Operator
          Services or, at ACI's discretion, directly to ACI Operator
          Services.

  4.4.5.4 Basic 911 and E911 access from the ACI local switch shall be
          provided from GTE to ACI in accordance with the following:

          4.4.5.4.1 If required by ACI and technically feasible, GTE shall
                    interconnect direct trunks from the ACI network to the
                    E911 PSAP, or to the E911 selective routers as
                    designated by ACI.  Such trunks may alternatively be
                    provided by ACI.

          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"), ACI
                    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 ACI 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.  ACI 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 ACI shall have the right to verify the accuracy of
                      information regarding ACI 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.

          4.4.5.4.3 If a Third Party is the primary service provider to a
                    911 district, ACI 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 ACI are totally separate from this Agreement and
                    GTE makes no representations on behalf of the Third
                    Party.

          4.4.5.4.4 If ACI or Affiliate is the primary service provider to
                    a 911 district, ACI 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.

                    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 ACI 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 ACI shall be solely responsible for providing ACI
                    database records to GTE for inclusion in GTE's ALI
                    database on a timely basis.

          4.4.5.5.4 GTE and ACI shall arrange for the automated input and
                    periodic updating of the E911 database information
                    related to ACI end users.  GTE shall work cooperatively
                    with ACI to ensure the accuracy of the data transfer by
                    verifying it against the Master Street Address Guide
                    ("MSAG").  GTE shall accept


                                     VIII-5

<PAGE>
                    electronically transmitted files or magnetic tape that 
                    conform to National Emergency Number Association ("NENA") 
                    Version #2 format.

          4.4.5.5.5 ACI shall assign an E911 database coordinator charged
                    with the responsibility of forwarding ACI end user ALI
                    record information to GTE or via a third-party entity,
                    charged with the responsibility of ALI record transfer. 
                    ACI assumes all responsibility for the accuracy of the
                    data that ACI provides to GTE.

          4.4.5.5.6 GTE shall update the database within one (1) business
                    day of receiving the data from ACI.  If GTE detects an
                    error in the ACI provided data, the data shall be
                    returned to ACI within one day from when it was
                    provided to GTE.  ACI 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 ACI subscribers
                    provided under this Agreement as strictly confidential
                    and to use data on ACI 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
                    ACI.  The Carrier Code will be used to identify the
                    carrier of record in NP configurations.  The NENA
                    Carrier Code for ACI is "ACI"; the NENA Carrier Code
                    for GTE is "GTE."

  4.4.5.6 GTE and ACI 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


                                     VIII-6

<PAGE>
                    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 ACI forty-eight (48) hours in advance
                    of any scheduled testing or maintenance affecting ACI
                    911 service.  GTE shall provide notification as soon as
                    possible of any unscheduled outage affecting ACI 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 ACI 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 ACI 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 ACI to ensure that 911 service is
                    fully available to all ACI end users whose telephone
                    numbers have been ported from GTE, consistent with
                    State provisions.

          4.4.5.7.2 ACI and GTE shall be responsible for reporting all
                    errors, defects and malfunctions to one another.  GTE
                    and ACI 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 ACI may enter into subcontracts with third parties,
                    including ACI Affiliates, for the performance of any of
                    ACI's duties and obligations stated herein.

          4.4.5.7.4 Where GTE is the lead telco, GTE shall provide ACI with
                    notification of any pending selective router moves
                    within at least ninety (90) days in advance..


                                     VIII-7

<PAGE>

          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 ACI 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 ACI access to the ALI Gateway which interfaces
          to the ALI/DMS database.  GTE shall provide error reports from
          the ALI/DMS database to ACI within one (1) day after ACI inputs
          information into the ALI/DMS database.  Alternately, ACI 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 ACI shall arrange for the automated input and periodic
          updating of the E911 database information related to ACI end
          users.  GTE shall work cooperatively with ACI 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 ACI
          subscriber's address from GTE, and where GTE is the lead telco,
          it shall be the responsibility of ACI to ensure that the address
          of each of its end users is included in the Master Street Address
          Guide ("MSAG") via information provided on ACI's Local Service
          Request ("LSR") or via a separate feed established by ACI
          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
          between the E911 Switch or Tandem and the ALI/DMS database for
          ACI 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 ACI's
     information by the municipality, GTE will seek such compensation from the
     municipality.


                                     VIII-8

<PAGE>

     GTE will seek compensation from ACI only if and to the extent that GTE is 
     unable to obtain such compensation from the municipality.  GTE shall 
     charge ACI a portion of the cost of the shared 911 /E911 selective router 
     as set forth in Appendix G.

5.   INFORMATION SERVICES TRAFFIC.

5.1  ROUTING.  Each Party shall route traffic for Information Services (I.E.,
     900-976, Internet, weather lines, sports providers, etc.) which originates
     on its network to the appropriate Information Service Platform.

5.2  BILLING AND COLLECTION AND INFORMATION SERVICE PROVIDER (ISP) REMUNERATION.

  5.2.1   In the event GTE performs switching of ISP traffic associated with
          resale or unbundled network elements for ACI, GTE shall provide to
          ACI GTE's standard call detail records so as to allow ACI to bill
          its end users.  GTE shall not be responsible or liable to ACI or
          ISP for Billing and Collection and/or any receivables of
          Information Service Providers.

  5.2.2   Notwithstanding and in addition to Article III, Section 24, GTE
          shall be indemnified and held harmless by ACI 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 5.2.1 supra.  The indemnity
          contained in this section shall survive the termination of this
          Agreement, for whatever reason.

  5.2.3   GTE agrees to notify ACI in writing within       working days, by
          registered or certified mail at                    of any claim made
          against GTE on the obligations indemnified against pursuant to this
          Section 5.

  5.2.4   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.

5.3  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 ACI.  ACI 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.

5.4  MISCELLANEOUS.  GTE reserves the right to provide to any Information
     Service Provider a list of any and all Telecommunications Providers doing
     business with GTE.


                                     VIII-9

<PAGE>

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, ACI'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 ACI is
     providing local service with its own switch, upon ACI's request GTE will
     provide to ACI rebranded or unbranded directory assistance services and/or
     operator services pursuant to separate contracts to be negotiated in good
     faith between the Parties.  If ACI 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 ACI 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 ACI end users in the same
     manner that call completion is provided to GTE end users.  GTE will provide
     its existing services to ACI end users consistent with the service provided
     to GTE end users.

7.2  OPERATOR SERVICES CALLS.  GTE operator services provided to ACI 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 ACI 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 ACI 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
     ACI 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 ACI end users in the same geographic
     area as GTE provides directory assistance for GTE end users as specified in
     Article VI, Section ?.

8.1  GTE shall provide to ACI, at ACI's request, for purposes of ACI providing
     ACI-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 Information under this Agreement and ACI will
     use the listings only for its directory assistance services to its end
     users.  If ACI uses a Third Party directory assistance service to its end
     users, ACI will ensure that such Third Party likewise


                                     VIII-10

<PAGE>

     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 ACI 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.  ACI 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.  ACI 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 ACI'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.

              ACI 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 ?, or if there is no
     applicable rate listed in APPENDIX ?, at the rates in their respective
     tariffs.

11.  SAG.  GTE will provide to ACI 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 ACI 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 ACI
     for ordering, provisioning and billing that are generally available as
     described in APPENDIX H attached to this Agreement and consistent with
     Commission and FCC decisions applicable to the Parties.

                                     COLLOCATION


1.   PHYSICAL COLLOCATION.  GTE shall provide to ACI physical collocation of
     equipment pursuant to 47 CFR Section 51.323 necessary for interconnection
     or for access to unbundled network elements.GTE will work with ACI to
     install physical collocation arrangements within 120 calendar days absent
     extenuating circumstances. 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.

     If GTE demonstrates that physical collocation is not practical because of 
     technical reasons or space limitations, as provided in Section 251(c)(6) 
     of the Act, GTE will provide ACI an alternative arrangement as described 
     in 2. below, subject to the Parties good faith resolution of 
     implementation issues.

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 based on future plans. If GTE denies ACI's
          application for initial or growth collocation space based on
          reserving space for GTE's future needs, and ACI disagrees with
          GTE's denial for space, GTE agrees to demonstrate to the Commission
          proper justification for GTE's reservation of space. 

  1.1.2   GTE will notify ACI if it plans to build an addition to a central
          office where ACI has collocated facilities, if such addition would
          result in a material increase of space available for collocation.

  1.1.3   Should ACI 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 ACI 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 ACI traffic.


                                     IX-1

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.

1.3  CONNECTION TO OTHER COLLOCATED CARRIERS.  Subject to technical feasibility
     and space limitations, ACI may interconnect with other carriers collocated
     at a GTE central office at which ACI has collocated facilities; provided,
     however, that ACI 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.  If ACI wants to interconnect
     with other carriers collocated at a GTE central office, ACI must provide
     GTE with thirty Business Days' prior written notice, during which time GTE
     may elect to provide the facilities necessary to accomplish such
     interconnection.  ACI and the other collocated carriers may provide the
     necessary interconnection facilities only if GTE elects not to provide such
     facilities or fails to so elect within the thirty day notice period.  If
     GTE elects 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.

1.4  CHOICE OF VENDOR.  ACI may use the vendor of its choice to install,
     maintain and repair equipment within ACI'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 ACI
     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, ACI
     may extend its own facilities for remote monitoring of its collocated
     equipment to its collocated space.  ACI may request that GTE provide the
     facilities necessary for such remote monitoring, at which time GTE and ACI
     will negotiate in good faith the price, terms and conditions of remote
     monitoring by GTE.

1.6  PHONE SERVICE.  Upon ordering collocated space, ACI may order that its
     collocation cage be provided with plain old telephone service (POTS) and/or
     ISDN, if available,  commencing at such time as GTE has completed
     construction of the collocated space.  ACI shall pay separately for any
     ordered POTS or ISDN service.

1.7  INTRAOFFICE DIVERSITY.  At ACI'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.


                                     IX-2

1.8  NOTIFICATION OF MODIFICATIONS.  GTE will notify ACI of modifications to
     collocation space in accord with the terms of applicable GTE state and
     federal EIS tariffs.  Additionally, GTE shall notify ACI when major
     upgrades are made to the power plants supporting ACI's collocation space. 
     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.

1.9  DRAWINGS.  When ACI orders collocated space, GTE and ACI 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 ACI's proposed
     collocation space.

1.10 CONSTRUCTION OF SPACE.  GTE, or a GTE approved contractor selected by ACI,
     will construct ACI's collocation space in accord with the terms and
     conditions set forth in the applicable GTE state and federal EIS tariff. 
     Additionally, GTE agrees to the following terms and conditions regarding
     construction of collocated space:

  1.10.1  Space will be constructed in 100 square foot increments, and shall
          be designed so as to prevent unauthorized access.

  1.10.2  A standard 100 square foot cage shall have the following standard
          features:

          (a) eight-foot high, nine gauge chain link panels;

          (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;

          (h) such additional lighting as may be necessary;

          (i) one fire detection requirement evaluation;

          (j) grounding for the cage consistent with COEI.

  1.10.3  Modifications to the standard configuration set forth in Section
          1.10.2 can be made on an individual case basis.  If modifications
          are agreed upon and made by the Parties, GTE will work with ACI to
          implement such additional modifications as may be necessary to
          ensure that ACI's collocated space is protected from unauthorized
          access.

  1.10.4  At such time as construction of ACI's collocation space is
          approximately 50 percent completed, GTE will give ACI notification,
          and such notification shall include scheduled completion and
          turnover dates.

  1.10.5  Upon completion of construction of collocated space, GTE will
          conduct a walk through of the collocated space with ACI.  Should
          ACI note any deviations from the plan agreed upon by GTE and ACI at
          the customer meeting, and if such deviations were not requested by
          ACI or not required by law, GTE shall correct such deviations at
          its own expense within 5 Business Days.

1.11 CONNECTION EQUIPMENT.  ACI may provision equipment for the connection of
     ACI termination equipment to GTE equipment using either of the following
     methods:

  1.11.1  ACI may extend an electrical or optical cable from the terminal
          within ACI's collocation cage and terminate that cable at GTE's
          network.

  1.11.2  ACI 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.

1.12 ACCESS TO ACI 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. ACI shall have access to its collocated equipment on a
     twenty-four hour, seven-days-a-week basis subject to reasonable security
     and safety controls.  Additionally, GTE agrees that the following terms and
     conditions shall apply to access:

  1.12.1  GTE shall implement adequate measures to control access to
          collocation cages.


                                     IX-4

<PAGE>

  1.12.2  Collocation space shall comply with all applicable fire and safety
          codes.

  1.12.3  Doors with removable hinges or inadequate strength shall be
          monitored by an alarm connected to a manned site.  All other alarms
          monitoring ACI collocation space provided by GTE shall also be
          connected to a manned site.  ACI may, at its option, provide its
          own intrusion alarms for its collocated space.

  1.12.4  GTE shall control janitorial access to collocation cages, and
          restrict such access to approved and certified employees, agents or
          contractors. 

  1.12.5  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.

  1.12.6  GTE shall retain a master key to ACI's collocation space for use
          only in event of emergency as detailed in applicable GTE state and
          federal tariffs.  At ACI's option, the Parties shall review key
          control procedures no more frequently than once in any twelve month
          period.  At any time, ACI 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.

  1.12.7  Not more frequently than once a year, ACI may audit the security
          and access procedures and equipment applicable to its collocated
          space and the 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
          ACI 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. Space for common
     collocation will be allocated within the same secured space as other forms
     of physical collocation; ie, caged collocation. Space will be made
     available in single frame bay increments and requests for multiple bay
     space will be provided n adjacent bays where possible. Space will be
     provided utilizing standard equipment bay configurations in which the
     collocator can place and maintain its


                                     IX-5

<PAGE>

     own equipment.  Access to the common collocation space will be on the 
     same terms as physical caged collocation in the same wire center.  Each 
     collocator shall be responsible for providing any additional security 
     measures to protect its equipment. The rates, terms, and conditions that 
     apply specifically to common collocation are TBD. To the extent not 
     inconsistent with these requirements, the remaining rates, terms, and 
     conditions for physical collocation shall apply to common collocation.

2.   ACCESS TO UNBUNDLED ELEMENTS. In order to provide the capability for ACI 
     to connect its facilities to GTE's unbundled elements at the wire center 
     where the elements are resident, the Parties agree to use the following 
     heirarchy of collocation options and alternatives to collocation:

2.1  If space is available, ACI will use physical (caged) collocation as
     described in Section 1. above.

2.2  If space is not available for physical collocation, ACI will use common 
     collocation as described in Section 1.14 above, provided that (1) common 
     collocation is either currently available or can be made available within
     120 days, and (2) sufficient space is available to meet ACI's reasonable 
     needs.

2.3  If space is not available for physical or common collocation, GTE will work
     with ACI to provide an alternate arrangement to access unbundled elements. 
     Such arrangements may include, but are not limited to, those described 
     below. GTE's ability to provide any specific arrangement or technology may 
     vary by location. Unless provided by GTE tariff, the technical 
     requirements and the rates, terms, and conditions of each arrangement 
     will be established on an individual case basis.

2.3.1     VIRTUAL COLLOCATION. Virtual collocation is provided pursuant to GTE
          Tariff.

2.3.2     CONNECTION TO AN INTERMEDIARY DISTRIBUTION FRAME. GTE will provide a 
          dedicated intermediary distribution frame (IDF) or dedicated space 
          on a shared IDF for ACI. ACI will be required to provide copper cable 
          facilities to connect the IDF to ACI's network. ACI will not have 
          access to GTE's building. ACI will hand off the building entrance 
          cable to GTE at the nearest man hole to GTE's building or another 
          mutually agreed upon location. GTE will pull the cable into GTE's 
          building and terminate it on the IDF. GTE will connect the IDF to 
          GTE's main distribution frame (MDF). Standard EIS cross connect 
          charges will apply to connect UNEs to the termination at the MDF.

2.3.3     CONNECTION TO THE MAIN DISTRIBUTION FRAME.  GTE will provide 
          dedicated copper cable facilities necessary to connect GTE's MDF 
          with ACI's network. GTE and ACI facilities will be connected at a 
          meet point in the nearest man hole to GTE's building or at another 
          mutually agreed upon location. GTE will


                                     IX-6

<PAGE>

          terminate the cable on the MDF. ACI will not have access to GTE's 
          building or GTE's cable other than at the meet point. Standard EIS 
          cross connect charges will apply to connect UNEs to the termination 
          at the MDF.

                                      ARTICLE X
                  ACCESS TO POLES, DUCTS, CONDUITS AND RIGHTS-OF-WAY


To the extent required by the Act, GTE and ACI 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 Parties tariffs and/or standard agreements.  Accordingly, if
either Party desires access to the other Party's poles, ducts, or rights of way,
GTE and ACI shall execute pole attachment and conduit occupancy agreements.

                         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.


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 $0.0053123.

       B.     The Tandem Switching rate element that applies to tandem routed 
              Local Traffic on a minute of use basis.  The tandem switching 
              rate is $0.0013054.

       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 $0.0000029.

       D.     The Common Transport Terminal element that applies to tandem 
              routed Local Traffic on a per minute/per termination basis.  
              The Common Transport Termination rate is $0.0001670.

              Tandem Switching:                                       =    $0.0013054

              Tandem Transport (10 mile average): 10 x $0.0000029     =    $0.0000290

              Transport Termination (2 Terminations): 2 x $0.0001670  =    $0.0003340

                   Transiting Charge:                                 =    $0.0016684

RATES AND CHARGES FOR INTERIM NUMBER PORTABILITY USING RCF


GENERAL.  GTE provides interim number portability using remote call forwarding
technology in it's tariff Cal. P.U.C. No. K-4. ACI agrees to use the same terms,
conditions, and charges when providing interim number portability using remote
call forwarding technology to GTE.

In addition, as defined in Article V, Section 3.2.3, the Party providing the
ported number will pay the other Party the rate per line per month for each
ported business line and the rate per line per month for each ported residential
line for the sharing of Access Charges on calls to ported numbers.

                           PRICES FOR UNBUNDLED ELEMENTS
                                          
                                          
GENERAL.  The rates contained in this APPENDIX F are the rates as defined in
Article VII, 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.

GTE will offer unbundled loops and ports under the following conditions:

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.  ACI agrees that within thirty (30) days after the effective date
         of a Commission or court order affirming GTE's interim surcharge,
         ACI will (i) begin paying the monthly interim surcharge in accord
         with Appendix F, and (ii) to the extent required by the terms of
         a Commission or court order relating to the interim surcharge,
         ACI will 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 ACI 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.

               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, ACI 
       will provide GTE with its Operating Company Number ("OCN") and Company 
       Code ("CC") as follows:

       (a)  ACI must provide their OCN (four-digit alpha-numeric assigned by
            Bellcore or number administrator) on the CLEC Profile. The GTE
            Guide provides the necessary information for ACI 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 ACI must provide the
            OCN and Customer Carrier Name Abbreviation ("CCNA").

1.1    OPERATIONS SUPPORT SYSTEMS FOR TRUNK-SIDE INTERCONNECTION

       1.1.1     ACI 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 ACI 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 ACI.  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 ACI'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 ACI.  ACI then will correct any errors that 
                 GTE has identified and resubmit the request to GTE 
                 electronically through a supplemental ASR, without penalty 
                 or charge (e.g., order modification charge) to ACI.  
                 Similarly, errors committed by GTE subsequent to the receipt 
                 of a valid ASR from 


                                     H-1
<PAGE>

                 ACI will be expeditiously identified and corrected by GTE 
                 without the need for ACI's submission of a supplemental ASR. 
                 GTE then will translate the ASR into a service order for 
                 provisioning and billing.  In order to convert the ASR into 
                 a service order, GTE personnel must apply the  necessary 
                 elements to provision the service and include the billable 
                 elements necessary for GTE to bill ACI for the services 
                 provided. This application also requires a determination of 
                 the access tandem to end office relationships with the 
                 service requested. 

       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 ACI.  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 ACI.  GTE's CZTs also will contact ACI 
                 directly to perform testing, and upon acceptance by ACI, 
                 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 ACI.  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 ACI.

1.2    OPERATIONS SUPPORT SYSTEMS FOR RESOLD SERVICES AND UNBUNDLED ELEMENTS

       1.2.1     ACI 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,  ACI 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 ACI 
                 chooses to establish a separate NDM interface, ACI 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 ACI 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 ACI 
                 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.  ACI 
                 will be able to obtain this customer information after GTE 
                 has received the customer's written consent as specified in 
                 Article VI.?.  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 ALEC data.  If known, the LSR should include 
                 the telephone number and due date/desired due date.

       1.2.3     While ACI would have its own customer information and may 
                 have the SAG/GTE products on tape from GTE, ACI 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 ACI. GTE itself does not have uniform access to this 
                 information electronically. Until GTE and ACI have agreed 
                 and established electronic interfaces, ACI agrees that an 
                 800 number is the method that will be used.  The 800 
                 telephone number will connect ACI directly to GTE's NOMC 
                 service representatives.  When ACI receives a request for 
                 basic services from a new local service customer, ACI will 
                 call GTE's NOMC through the 800 number, and, while the new 
                 customer is on

                 hold, GTE will provide the due date for service and the new 
                 telephone number for that customer.  At the same time, ACI 
                 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 ACI sends the 
                 confirming LSR.  ACI 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, 
                 ACI 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 ACI through the NDM 
                 that the LSR has been processed, providing a record of the 
                 telephone number and due date.  ACI 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 ACI 
                 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 ACI 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 
                 ACI 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 
                 ACI on a real time interface to process vanity numbers while 
                 ACI'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 ACI 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

       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 ACI 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 ACI's account is referred to 
                 as the ACI 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 ACI a service completion report.  Call records for actual 
                 service provided to ACI'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 ACI 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 
                 ACI's accounts  will be generated and transmitted 
                 electronically to ACI.

       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 ACI to issue a bill to 
                 its end users.

       1.2.11    GTE will provide ACI 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 ACI's control reports and agrees to utilize 
                 industry standard return codes for unbillable messages.  
                 Transmission will 


                                     H-5

                 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.  To the 
                 extent this retention is exclusively for ACI, ACI shall 
                 reimburse GTE for all expenses related to this retention.

       1.2.15    In addition to the LSR delivery process, ACI 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 ACI places a request for a 
                 PIC change via LSR, the billing will be made on ACI account 
                 associated with each individual end user.  GTE will process 
                 all PIC changes from IXCs that are received for ACI end 
                 users by rejecting back to the IXC with the ACI OCN.  Detail 
                 is provided so that ACI 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 ACI'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 ACI 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 ACI.  
                             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 
                             format. GTE intraLATA toll 


                                     H-6
<PAGE>

                             messages that are recorded by GTE and dialed on 
                             a one plus or zero plus basis are not part of 
                             this section and will not be screened.

                 1.2.17.2    COMPENSATION.  GTE will bill ACI 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 ACI's incollect messages that are charged 
                             to GTE by the CMDS Host will be passed on to ACI 
                             on the monthly statement.  All revenue, 
                             surcharges, taxes and any other amounts due to 
                             the CMDS Host for ACI's incollect messages will 
                             be billed on the monthly statement.  It is ACI'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 ACI.

                 1.2.17.3    ADMINISTRATION.  The Parties agree to develop a 
                             process whereby ACI'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 ACI.

       1.2.18    BACKBILLING.  GTE shall bill ACI on a timely basis.  In no 
                 case shall GTE bill ACI for previously unbilled charges that 
                 are for more than one year prior to the current bill date.

1.3    ORDER PROCESSING.

       1.3.1     ORDER EXPECTATIONS.  ACI agrees to warrant to GTE that it is 
                 a certified provider of telecommunications service.  ACI 
                 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, ACI shall obtain such documentation as 
                 may be required by state and federal laws and regulations.

       1.3.2     GTE shall provide ACI 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 ?.  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 a ACI end user 
                 changes to another LSP, GTE will notfiy ACI when such 
                 activity occurs the day after completion or within 48 hours 
                 of such disconnect.

2.     MAINTENANCE SYSTEMS.

2.1    GENERAL OVERVIEW

       2.1.1     If ACI requires maintenance for its local service customers, 
                 ACI 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 a ACI customer and will 
                 then obtain the necessary information from ACI to process 
                 the trouble report.  While the ACI representatives are still 
                 on the line, GTE personnel will perform an initial analysis 
                 of the problem and remote line testing for resale services.  
                 If engineered services are involved, the call will be made 
                 to the GTE 


                                     H-8
<PAGE>

                 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 ACI representatives are still on the line.  If 
                 on-line resolution is not possible, GTE personnel will provide
                 ACI representatives a commitment time for repair, and the GTE 
                 personnel then will enter the trouble ticket into the GTE 
                 service dispatch queue.  ACI'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 ACI.  If, as a result of a ACI-initiated trouble 
                 report, trouble is found to be the responsibility of ACI (e.g.,
                 non-network cause) GTE will charge ACI for trouble isolation.  
                 ACI will have the ability to report trouble for its end users 
                 to appropriate trouble reporting centers 24 hours a day, 7 days
                 a week.  ACI 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 ACI 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 ACI 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 ACI becomes in 
                 jeopardy, GTE service representatives will contact ACI 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 ACI trouble reports, GTE service technicians 
                 will make a telephone call to ACI directly to clear the 
                 trouble ticket.  GTE service technicians will make the 
                 confirmation call to the telephone number provided by ACI.  
                 If ACI is unable to process the call or places the GTE 
                 technician on hold, the call will be terminated.  To avoid 
                 disconnect, ACI may develop an answering system, such as 
                 voice mail, to handle the confirmation calls expeditiously.  

       2.1.5     GTE will provide electronic interface access to operation 
                 support systems functions which provide the capability to 
                 initiate, status 


                                     H-9
<PAGE>

                 and close a repair trouble ticket.  GTE will not provide to 
                 ACI real time testing capability on ACI end user services. 
                 GTE will not provide to ACI an interface for network 
                 surveillance (performance monitoring).

       2.1.6     GTE will resolve repair requests by or for ACI 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 ACI using the same time parameters and 
                 procedures that GTE uses.  ACI 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.

3.1    ACI shall have immediate access to the following OSS electronic 
       interfaces that will provide functionality to enable ACI to service 
       customers in an equal and non-discriminatory manner:

       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).


                                    H-10
<PAGE>

       3.1.2     Order functions that are available on a dial-up or dedicated 
                 basis using CONNECT:  Mail file transfer.

       3.1.3     Initial trouble reports via SIGS.

       3.1.4     Electronic transfer of the ACI bill in electronic data 811
                 format.

3.2    ACI may migrate to fully interactive system to system 
       interconnectivity. GTE, with input from ACI and other carriers, shall 
       provide general interface specifications for electronic access to this 
       functionality. These specifications will be provided to enable ACI 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    All costs and expenses for any new or modified electronic interfaces 
       exclusively to meet ACI requirements that GTE determines are 
       technically feasible and GTE agrees to develop will be paid by ACI.  
       Costs for development of systems intended for common use by competing 
       carriers will be assessed based on a mutually agreed method of cost 
       recovery.

3.4    ACI 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 ACI 
       when GTE initiates its own electronic system 
       redesigns/reconfigurations.

               for terminating usage will be equal to the number of 
               originating minutes.  The Parties will mutually agree on 
               a method and procedure to periodically sample and 
               validate or adjust the ratio of originating to 
               terminating minutes for billing purposes.

                             INTERCONNECTION AGREEMENT

       This Interconnection Agreement, made as of the __ day of _____, 1998, is
between ACI, CORP. ("ACI"), a Delaware corporation and U S WEST COMMUNICATIONS,
INC. ("USWC"), a Colorado corporation.


1.     RECITALS

       
       1.1      Pursuant to this Interconnection Agreement ("Agreement"), ACI,
                Corp. ("ACI"), a Competitive Local Exchange Carrier and USWC
                (collectively, "the Parties") will extend certain arrangements
                to one another within each LATA in which they both operate
                within the state of ________.  This Agreement  includes
                terms, conditions, and prices for network interconnection,
                access to unbundled network elements, ancillary network
                services, and retail services available for resale.  It will be
                submitted to the __________________________________________
                __________.   Notwithstanding this mutual commitment, however,
                the Parties enter 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 matters related to the types
                of arrangements prescribed by this Agreement.

       1.2      The Parties have agreed to certain provisions in this 
                Agreement, based, in large part, on the existing state of the 
                law, rules, regulations and interpretations thereof, as of 
                the date hereof (the "Existing Rules").  To the extent that 
                certain of the Existing Rules are changed and modified, and 
                it reasonably appears that the Parties would have negotiated 
                and agreed to different term(s), condition(s), or covenant(s) 
                than as contained herein had such change or modification been 
                in existence before execution hereof, then this Agreement 
                shall be amended to reflect such different term(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.

2.     SCOPE OF AGREEMENT

                local traffic between USWC and ACI 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.
       
       2.2      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.

                NXX code and 4-digit line number.
                
       3.31     "NXX" means the fourth, fifth and sixth digits of a ten-digit
                telephone number.
                
       3.32     "Party" means either USWC or ACI and "Parties" means USWC and
                ACI.
       
       3.33     "Point of Interface", "Point of Interconnection", or "POI" is a
                mutually agreed upon point of demarcation where the exchange of
                traffic between two LECs (including a LEC and a Co-Provider)
                takes place.
       
       3.34     "Port" means a termination on a Central Office Switch that
                permits end users to send or receive telecommunications
                services over the public switched network, but does not include
                switch features or switching functionality.
                
       3.35     "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 Co-Provider) 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 Co-Provider) 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.
       
       3.36     "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 users.

                                                                        PAGE 11

       3.37     "Routing Point" means a location that a LEC or Co-Provider 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 Co-Provider.  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 must be located
                within the rate center area.
       
       3.38     "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.
       
       3.39     "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.
                
       3.40     "Switched 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 Access Services include:  Feature Group A,
                Feature Group B, Feature Group D, 800/888 access, and 900
                access and their successors or similar Switched Access
                services.
       
       3.41     "Tariff" as used throughout this Agreement refers to USWC
                interstate tariffs and state tariffs, price lists, price
                schedules and catalogs.
       
       3.42     "Telecommunications Carrier" means any provider of
                telecommunications services, except that such term does not
                include aggregators of telecommunications services (as defined
                in Section 226 of the Act).  A Telecommunications Carrier shall
                be treated as a common carrier under the Act only to the extent
                that it is engaged in providing telecommunications services,
                except that the Commission shall determine whether the
                provision of fixed and mobile satellite service shall be
                treated as common carriage.
       
       3.43     "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 appropriate state
                commission for the incumbent LEC.

                                                                        PAGE 12

<PAGE>

       3.44     "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 Center shall
                mean those points eligible for such connections as specified in
                the FCC Docket No. 91-141, and rules adopted pursuant thereto.
       
       3.45     Terms not otherwise defined here, but defined in the Act or in
                regulations implementing the Act, shall have the meaning
                defined there.


4.     RATES AND CHARGES GENERALLY

       4.1      Prices for termination and transport of traffic,
                Interconnection, access to unbundled Network Elements, and
                ancillary services are set forth in Appendix A.

       4.2      USWC's wholesale discounts for resale services are set forth in
                Appendix A.
       
       4.3      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.
       
       
5.     RECIPROCAL TRAFFIC EXCHANGE

       5.1      SCOPE
       
                Reciprocal traffic exchange addresses the exchange of traffic
                between ACI 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.
       
       5.2      TRAFFIC TYPES
       
                The Traffic Types to be exchanged under this Agreement include:
       
                5.2.1    EAS/Local Traffic as defined above.
                
                5.2.2    IntraLATA Toll traffic as defined above.

                                                                        PAGE 13

<PAGE>

                5.2.3    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.
                
                5.2.4    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 Co-Provider, an existing LEC, 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.
       
                5.2.5    Ancillary traffic includes all traffic destined for
                         ancillary services, or that may have special billing
                         requirements, including, but not limited to the
                         following:
                
                         5.2.5.1   Directory Assistance
                         5.2.5.2   911/E911
                         5.2.5.3   Operator call termination (busy line
                                   interrupt and verify)
                         5.2.5.4   800/888 database dip
                         5.2.5.5   LIDB
                         5.2.5.6   Information services requiring special
                                   billing.
                
                5.2.6    Unless otherwise stated in this Agreement, ancillary
                         traffic will be exchanged in accordance with whether
                         the traffic is EAS/Local, IntraLATA Toll, or Switched
                         Access.
                
       5.3      TYPES OF EXCHANGED TRAFFIC
       
                5.3.1    Termination of Local Traffic.  
                         
                         Local traffic will be terminated as Local
                         Interconnection Service (LIS).
                         
                5.3.2    Transport of Local Traffic

                                                                        PAGE 14

                         As negotiated between the Parties, the exchange of
                         local traffic between the Parties may occur in several
                         ways:
                         
                         5.3.2.1   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.
                         
                         5.3.2.2   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 or direct
                                   trunk transport.
                         
                         5.3.2.3   Based on forecasted traffic at ACI's busy
                                   hour in CCS, where there is a DS1's worth of
                                   traffic (512 CCS) between the ACI switch and
                                   a USWC end office, the traffic will be moved
                                   to a dedicated (i.e., direct) trunk group
                                   from the ACI switch directly to the USWC end
                                   office.  To the extent that ACI has
                                   established a collocation arrangement at a
                                   USWC end office location, and has available
                                   capacity, the Parties agree that ACI shall
                                   provide two-way direct trunk facilities, when
                                   required, from that end office to the ACI
                                   switch.  In all other cases, the direct
                                   facility may be provisioned by USWC or ACI or
                                   a third party.  If both ACI and USWC desire
                                   to provision the facility and cannot
                                   otherwise agree, the Parties may agree to
                                   resolve the dispute through the submission of
                                   competitive bids.
                         
                5.3.3    Transit Traffic.  
                
                         5.3.3.1   USWC will accept traffic originated by ACI
                                   and will terminate it at a Point of
                                   Interconnection with another Co-Provider,
                                   LEC, IXC, or wireless carrier.  USWC will
                                   provide this transit service through local
                                   and access tandem switches.  ACI may also
                                   provide USWC with transit service.
                         
                         5.3.3.2   To the extent technically feasible, the
                                   Parties involved in transporting transit
                                   traffic will deliver calls to each involved
                                   network with CCS/SS7 protocol and the

                         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

                                   capability for such additional switches. 
                                   Prices for such additional Clear Channel 
                                   Capability, if any, will be established 
                                   through the BFR 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 ACI with a 
                                   listing of USWC end offices, local tandems 
                                   and access tandems equipped with Clear 
                                   Channel Capability.

       5.6      MEASURING LOCAL INTERCONNECTION MINUTES

                5.6.1    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 ACI's Point of Interconnection,
                         whichever is recognized first by the entry switch.

                5.6.2    USWC and ACI are required to provide each other the
                         proper call information (e.g., originating call party
                         number and destination call party number, etc.) to
                         enable each Party to issue bills in a complete and
                         timely fashion.
       
       5.7      TESTING

                5.7.1    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 

                                                                        PAGE 19

                                   digital loopback (108 type).

                         5.7.2.2   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.

       5.8      ORDERING
                         
                5.8.1    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 ACI end office; 4) the number of trunks to
                         be provisioned at a local exchange office or tandem; 5)
                         and any optional features.  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.
                         
                5.8.2    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.  On subsequent orders
                         utilizing existing DS3 Interconnection facilities, or
                         DS3 Direct Trunk Transport facilities, the provider
                         will assign the DS1 facility to the DS3 Interconnection
                         facility or DS3 Direct Trunk Transport facility, as
                         directed by the ordering Party.
                         
                5.8.3    A joint planning meeting will precede ACI 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.

                                                                        PAGE 20

                5.8.4    Service intervals and due dates for the initial
                         establishment of trunking arrangements at each location
                         of Interconnection between the Parties will be
                         determined on an individual case basis.
                
                5.8.5    Service intervals and due dates for the establishment
                         of subsequent trunking arrangements for Interconnection
                         between the Parties, will be in accordance with the
                         guidelines for LIS.
                         
       5.9      BILLING ARRANGEMENTS
                
                5.9.1    USWC and ACI 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
                         ACI sub-tends in each LATA.
                         
                5.9.2    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. 
                
                5.9.3    As detailed in the MECAB document, ACI and USWC will
                         exchange all information necessary to bill third
                         parties for Switched Access Services traffic jointly
                         handled by ACI 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.
                
                5.9.4    The Parties will agree upon reasonable audit standards
                         and other procedures as required to ensure billing
                         accuracy.
                
                5.9.5    Each Party will bill the IXCs the appropriate rate
                         elements in accordance with their respective interstate
                         and intrastate tariffs, as follows:

6.     INTERCONNECTION
       
       6.1      DEFINITION
       
                6.1.1    "Interconnection" is the linking of the USWC and ACI
                         networks for the mutual exchange of traffic and for ACI
                         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 Mid-Span
                         Meet arrangements.

                6.1.2    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 the location
                         of the signaling transfer points necessary to exchange
                         traffic and access call related databases.
       
       6.2      MID-SPAN MEET POI
       
                6.2.1    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 

                                                                        PAGE 22

<PAGE>

                         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.
                
                6.2.2    If the Mid-Span Meet arrangement is to be used for
                         access to unbundled Network Elements, ACI must pay the
                         portion of the economic costs of the Mid-Span Meet
                         arrangement used by ACI for access to unbundled Network
                         Elements.
                
       6.3      COLLOCATION

                Interconnection may be accomplished through either Virtual or
                Physical Collocation.  The terms and conditions under which
                Collocation will be available are described in the Collocation
                section of this Agreement.
                
       6.4      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 Wire
                Center 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. 
                
       6.5      QUALITY OF INTERCONNECTION

                USWC will not, for the purpose of Interconnection, provide to
                ACI 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.  
                         
                Both Parties agree to manage their network switches in
                accordance with the Bellcore LSSGR.  
                         
       6.6      POINTS OF INTERFACE (POI)
       
                UPON THE REQUEST FOR SPECIFIC POINT TO POINT ROUTING, USWC WILL
                MAKE AVAILABLE TO ACI INFORMATION INDICATING THE LOCATION AND
                TECHNICAL CHARACTERISTICS OF USWC'S NETWORK FACILITIES.  THE
                FOLLOWING ALTERNATIVES ARE NEGOTIABLE:  (1) A DS1 OR DS3
                ENTRANCE FACILITY; (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.
                
       6.7      TRUNKING REQUIREMENTS
       
                6.7.1    The Parties agree to provide designed Interconnection
                         facilities that meet the same technical criteria and
                         service standards, such as probability of 

                                                                        PAGE 23

                         blocking in peak hours and transmission standards, in
                         accordance with industry standards.
                
                6.7.2    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.
       
                         6.7.2.1   IntraLATA Toll and Switched Access trunks
                         6.7.2.2   EAS/Local trunks
                         6.7.2.3   Directory Assistance trunks
                         6.7.2.4   911/E911 trunks
                         6.7.2.5   Operator services trunks
                         6.7.2.6   Commercial Mobile Radio Service/Wireless
                                   traffic for which ACI serves as the transit
                                   provider between the CMRS provider and USWC.
                         6.7.2.7   Transit IntraLATA Toll 
                         6.7.2.8   Transit local
                         6.7.2.9   Meet-Point Billing Trunks (for the joint
                                   provision of Switched Access)
                         6.7.2.10  Mass calling trunks, if applicable
       
                6.7.3    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.
       
                6.7.4    The Parties will provide Common Channel Signaling (CCS)
                         to one another, where available, in conjunction with
                         all EAS/Local 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.
                
                6.7.5    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
                         signaling.
                
                6.7.6    The Parties will follow all Ordering and Billing Forum
                         adopted standards pertaining to CIC/OZZ codes.
                
                6.7.7    USWC will cooperate in the provision of TNS (Transit
                         Network Selection) for the joint provision of Switched
                         Access Service.

                                                                        PAGE 24
<PAGE>

                6.7.8    The Parties shall terminate EAS/Local traffic
                         exclusively on EAS/Local trunk groups.  No EAS/Local
                         trunk groups shall be terminated on USWC's access
                         tandems.
                         
                6.7.9    The Parties agree to terminate local traffic in the
                         same EAS/Local area as such traffic originated. 
                         
       6.8      INTERCONNECTION FORECASTING
       
                6.8.1    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.

                6.8.2    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 6.7.2 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
                         and shall include: 

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

                         6.8.2.2   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.

                6.8.3    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.

                6.8.4    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.  

                                                                        PAGE 25

<PAGE>

                6.8.5    Each Party shall provide a specified point of contact
                         for planning, forecasting and trunk servicing purposes.
                         
       6.9      SERVICE INTERRUPTIONS
                         
                6.9.1    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.
                
                6.9.2    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".
                
                6.9.3    If, either Party discovers an impairment or
                         interference that threatens to cause, is causing, or
                         has caused service-affecting harm to the physical
                         integrity of the network, physical harm to either
                         Parties' employees or third parties or interference
                         which prevents either Party, or third parties, from
                         offering service to their end-users, such impairment or
                         inference may be considered an emergency situation and
                         that Party shall, where practical, promptly notify the
                         other Party of the nature and location of the
                         impairment or interference. The Parties agree to work
                         together to attempt to promptly resolve the emergency
                         situation and if Parties are unable to resolve it, or
                         if exigent circumstances exist, either Party may take
                         any action permitted by applicable law, including the
                         temporary disconnection of the affected circuit,
                         facility or equipment.  The Parties contemplate that
                         the provision of services within industry standards,
                         norms, or generally accepted practices will not
                         constitute an emergency situation.

                         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.
                
                6.9.5    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

                         location that is staffed and has the authority to
                         initiate corrective action.
                
                6.9.6    Before either Party reports a trouble condition, each
                         shall use its best efforts to isolate the trouble to
                         the other's facilities.
                         
                         6.9.6.1   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.
                                   
                         6.9.6.2   The Parties shall cooperate in isolating
                                   trouble conditions.

                                   both Virtual and Physical Collocation, 
                                   Common Collocation will also include 
                                   access to the SPOT Frame in which ACI can 
                                   make connections to USWC UNEs.
                
       7.2.     TERMS AND CONDITIONS
                
                7.2.1    Terms and Conditions - General

                                   conditions that are just, reasonable and
                                   nondiscriminatory.
                
                         7.2.1.2   ACI will only  collocate basic transmission
                                   equipment, including equipment necessary to
                                   provide DSL services, to interconnect with
                                   USWC's UNEs and/or terminate EAS/local
                                   traffic to USWC.  ACI must identify what
                                   transmission equipment will be installed and

                                   equipment so that USWC may engineer the
                                   power, floor loading, heat release,
                                   environmental particulate level, and HVAC.
                         
                         7.2.1.3   Collocation requests require that space be
                                   provided for the placement of [Co-Provider's]
                                   transmission equipment within USWC's Central

                                   Technical Publication 77390. 
                 
                         7.2.1.5   Collocation is offered on a first-come,
                                   first-served basis.  Requests for Collocation
                                   may be denied due to the lack of sufficient
                                   space in a USWC Central Office for placement
                                   of  ACI's equipment.  When ENTRANCE
                                   FACILITIES space is not available, ACI may
                                   opt to utilize USWC Private Line Finished
                                   Services in lieu of entrance facilities. 
                                   USWC is not required to build new entrance
                                   facilities or construct new office space
                                   solely for the purposes of Collocation.  In
                                   the event that USWC requires additional
                                   Central Office space in order 

                                                                        PAGE 28

                                   to satisfy its own business needs, 
                                   additional space  will be taken into 
                                   consideration for Collocation as well. 
                
                         7.2.1.6   If a request for Collocation is denied due to
                                   a lack of space in a USWC Central Office, ACI
                                   may request USWC to provide a cost quote for
                                   the reclamation of space and/or equipment.
                                   Quotes will be developed within 60 business
                                   days including the estimated time frames for
                                   the work that is required in order to satisfy
                                   the Collocation request.  ACI has 30 days to
                                   accept the quote. If ACI accepts the quote,
                                   upon receipt of 50% down of the quoted 
                                   charges, work will begin with the balance due
                                   on completion. 
                
                         7.2.1.7   If space is limited in USWC's Central
                                   Offices,  Collocation space will always be
                                   provided for placement of a SPOT frame for
                                   all Collocation requests.  This may include
                                   having to reclaim either space or equipment.
                                   All costs associated with allocating space
                                   directly related to the SPOT Frame will be
                                   borne by USWC.  
                
                         7.2.1.8   Reclamation may include the following:
                
                                   USWC is responsible for Equipment

                                   similar functionality for the
                                   purpose of providing space for
                                   Interconnection. 
       
                                   ACI is responsible for Space
                                   Reclamation -  Administrative space
                                   that can be re- conditioned for the
                                   placement of transmission equipment.
       
                                   If ACI's request for reclamation
                                   produces additional capacity in
                                   excess of ACI's requested amount of
                                   collocation space, ACI will be
                                   responsible, on a pro-rated basis,
                                   pursuant to Section 7.2.1.8. only

                                   necessary to satisfy its collocation
                                   request.
       
                         7.2.1.9   If USWC determines that the amount of space
                                   requested by ACI for Physical Collocation is
                                   not available, ACI will be offered
                                   Collocation in the closest 100 square foot
                                   increment that is determined to be available

                                   allowed access to the POI on
                                   non-discriminatory terms. 

                                                                        PAGE 29

                         7.2.1.11  ACI is responsible for providing its own
                                   fiber facilities to the (POI) outside USWC's
                                   Central Office.  USWC will extend the fiber
                                   facility on a USWC fiber cable from the POI
                                   to a Fiber Distribution Panel (FDP).  From
                                   the FDP additional fiber, conduit and
                                   associated riser structure will then be
                                   provided by USWC to continue the run to ACI's
                                   transmission equipment or collocation area.
                
                         7.2.1.12  The entrance facility must be fiber optic
                                   cable and meet industry standards (GR. 20
                                   Core).  Metallic sheath cable is not
                                   permitted for use as an entrance facility for
                                   the purpose of Interconnection.  USWC
                                   reserves the right to refuse cable that does
                                   not meet requirements for entrance
                                   facilities.
                
                         7.2.1.13  Dual entry into a USWC Central Office will be
                                   provided only when two entry points
                                   previously exist and duct space is available.
                                   USWC will not initiate construction of an
                                   entrance facility solely for Collocation.  If
                                   USWC requires an entrance facility for its
                                   own use, then the needs of ACI will also be
                                   taken into consideration.

                         7.2.1.14  Where no entrance facilities are available,
                                   USWC will offer ACI USWC Private Line
                                   Finished Services in lieu of entrance
                                   facilities to be terminated at ACI's
                                   collocated equipment.

                         7.2.1.15  USWC will establish a SPOT Frame to be the
                                   single point where all USWC UNEs and ACI
                                   equipment are terminated.  The SPOT Frame
                                   becomes the standard demarcation point
                                   between ACI and USWC owned network facilities
                                   and equipment as well as the demarcation
                                   between UNEs.  ACI will run jumpers on this
                                   SPOT Frame to connect the network elements. 
                                   There are three basic types of connections
                                   that will be made at the SPOT Frame:
                
                                        Unbundled Element to Unbundled
                                        Element
                                   
                                        Unbundled Element to ACI equipment
                                        termination
                                   
                                        ACI equipment termination to
                                        Co-Provider equipment termination
                                   
                         7.2.1.16  All terminations on the SPOT Frame will have
                                   a cable CFA address.  USWC will assign and
                                   maintain cable CFA records for the
                                   terminations at the SPOT frame.  USWC will
                                   provide the cable CFA to ACI for subsequent
                                   unbundled network element ACI orders.  ACI
                                   will maintain assignment records for the
                                   terminations of its own equipment.  ACI will
                                   also maintain the assignment records for
                                   which SPOT frame addresses are connected to
                                   combine network elements and deliver service.
                                   ACI will be required to make the jumper wire,
                                   cross connection between frame addresses on
                                   the SPOT frame to complete the standard
                                   circuit.

                                                                        PAGE 30

                         7.2.1.17  ACI will be required to forecast for all DS0,
                                   DS1 and DS3 terminations that it requires for
                                   each Wire Center for which it is requesting
                                   Collocation. The forecast is, including a
                                   separate forecast for UNEs ACI wishes to
                                   combine, included as part of the Collocation
                                   order form and will be used to pre-provision
                                   the necessary tie cables from the Collocation
                                   space to the SPOT Frame and from the SPOT
                                   Frame to USWC UNEs. Terminations  will be
                                   provisioned in following increments:
                                   
                                           DS0- 100 pair increments
                                           
                                           DS1- 28 channel increments
                                           
                                           DS3- per termination

                         7.2.1.18  USWC will review the security requirements
                                   and hours of access (seven (7) days a week,
                                   twenty-four (24) hours a day) with ACI. This
                                   will include issuing keys, ID cards, and
                                   explaining the access control processes,
                                   including but not limited to the requirement
                                   that all ACI approved personnel are subject
                                   to trespass violations if outside of
                                   designated and approved areas or if found to
                                   be providing access to unauthorized
                                   individuals.

                         7.2.1.19  USWC shall provide access to existing eyewash
                                   stations, bathrooms, and drinking water

                         7.2.3.1   USWC shall provide to ACI Physical
                                   Collocation for Interconnection and for
                                   access to UNEs, except that USWC may provide
                                   for Common or 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 basic telephone service
                                   with a connection jack as requested by ACI
                                   for the Physical or Common Collocated space. 
                                   Upon ACI's request, this service shall be
                                   available per standard USWC business service
                                   provisioning processes.
                
                         7.2.3.2   Physical Collocation is offered in Wire
                                   Centers on a space-available, first come,
                                   first-served basis.
                                           
                         7.2.3.3   The minimum standard leasable amount of floor
                                   space is 100 square feet.  ACI 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.
                                           
                         7.2.3.4   ACI's leased floor space will be separated
                                   from other Co-Providers and USWC space
                                   through a cage enclosure.  USWC or a USWC
                                   approved contractor will construct the cage
                                   enclosure. These two Technical Publications
                                   must be in the possession of ACI and its
                                   agents at the site during all work
                                   activities.  
                         
                         7.2.3.5   The following standard features will be
                                   provided by USWC:
                                           
                                        Heating, ventilation and air    
                                        conditioning.
                
                                        Smoke/fire detection and any
                                        other building code
                                        requirements.
                                                    
                         7.2.3.6   USWC will design the floor space within each
                                   Wire Center which will constitute ACI's
                                   leased space.
                                                    
                         7.2.3.7   USWC will ensure that the necessary
                                   construction work (racking, ducting, caging,
                                   etc.) is performed to build ACI's leased
                                   physical space and the riser from the vault
                                   to the leased physical space. 
                
                         7.2.3.8   ACI owns and is responsible for the
                                   installation, maintenance and repair of its
                                   transmission equipment located within the
                                   physically collocated space rented from USWC.
                
                         7.2.3.9   ACI must use leased space promptly and may
                                   not warehouse space for later use or sublease
                                   to another Co-Provider.
                
                         7.2.3.10  USWC will extend USWC-provided and owned
                                   fiber optic cable from the POI through the
                                   cable vault and extend the cable to the 

                                                                        PAGE 33

                                   Fiber Distribution Panel and then to
                                   ACI's leased physical space or place
                                   the cable in fire retardant tubing
                                   prior to extension to ACI's leased
                                   physical space. ACI will, procure,
                                   install and maintain all fiber optic
                                   facilities up to the USWC designated
                                   POI.
                
                         7.2.3.11  USWC will install and maintain all related
                                   SPOT frame activity necessary to provide
                                   cross connections between USWC's and ACI's
                                   equipment.    
                
                         7.2.3.12  ACI may not extend USWC dark fiber to ACI's
                                   leased physical space or connect DS1/DS3
                                   Channel Terminations to USWC dark fiber.
                
                         7.2.3.13  USWC will work cooperatively with ACI in
                                   matters of joint testing and maintenance.
                
                         7.2.3.14  Once construction is complete for Physical
                                   Collocation and ACI has accepted its leased
                                   physical space, ACI may order its DS0, DS1,
                                   DS3.
                
                         7.2.3.15  If, during installation, USWC determines ACI
                                   activities or equipment does not comply with
                                   the NEBS standards listed in section 7.2.1.4
                                   or are otherwise unsafe, non-standard, or in
                                   violation of any applicable laws or
                                   regulations, USWC has the right to stop all
                                   collocation 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, cable facilities, or
                                   other equipment in the central office USWC
                                   may perform such work and/or take action as
                                   is necessary to correct the condition at
                                   ACI's expense.
                
                         7.2.3.16  If, at any time, USWC determines that the
                                   equipment or the installation does not meet
                                   USWC standards as listed in Section 7.2.1.4,
                                   ACI will be responsible for the costs
                                   associated with the removal, modification to,
                                   or installation of the equipment to bring it
                                   into compliance.  If ACI 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 ACI's expense.
                
                7.2.4    Terms and Conditions - Common Collocation
                
                         7.2.4.1   ACI owns and is responsible for the
                                   installation, maintenance and repair of its
                                   transmission equipment located within the
                                   space rented from USWC.  USWC will not
                                   interfere with such ACI equipment and will
                                   make best efforts to ensure that third
                                   parties will not have access to, will not
                                   physically touch, and/or functionally impact
                                   the operation of any ACI equipment, spares,
                                   or test equipment.  USWC will not 

                                                                        PAGE 34

                                   operating circumstances; however, USWC 
                                   cannot agree under any circumstances, 
                                   never access, physically touch, and/or 
                                   functionally impact ACI's equipment. 
                                   Additionally, with respect to the 
                                   requirement set forth to not functionally 
                                   impact ACI's equipment, please refer to 
                                   Section 6.9.2 and 6.9.3 which USWC and ACI 
                                   have had extensive discussions.  ACI does 
                                   not have access to, will not physically 
                                   touch, and/or functionally impact the 
                                   operation of any adjacent USWC equipment, 
                                   spares, or test equipment.
                
                         7.2.4.2   Requests for multiple bay space will be
                                   provided in adjacent bays where possible. 
                                   When contiguous space is not available, bays
                                   may be co-mingled with other USWC or other
                                   co-provider equipment bays.  ACI may request

                                   ACI and its agents at the site during all
                                   work activities.
                
                         7.2.4.4   All equipment placed will be subject to
                                   random audits conducted by USWC.  These
                                   audits will determine whether the equipment
                                   meets the standards required by this
                                   Agreement.  ACI will be notified of the
                                   results of this audit and shall rectify all
                                   non-conformities within 30 days of

       7.5. BILLING

                7.5.1    Billing - Collocation

                         Upon completion of the Collocation construction
                         activities and payment of the remaining nonrecurring
                         balance, USWC will provide ACI a completion package
                         that will initiate the recurring Collocation charges. 
                         Once this completion package has been signed by ACI and
                         USWC, ACI may begin submitting service order requests
                         for USWC transport services and/or UNEs.
                         
                7.5.2    Billing - Virtual Collocation
       
                         Virtual Collocation will be considered complete when
                         the POI has been constructed, the shared fiber entrance
                         facility has been provisioned, and the collocated
                         equipment has been installed.  Cooperative testing
                         between ACI and USWC may be negotiated and performed to
                         ensure continuity and acceptable transmission
                         parameters in the facility and equipment.

                         Upon completion of the construction activities and
                         payment of the remaining nonrecurring charge, USWC will
                         turn over access to the space and provide security
                         access to the Wire Center.  ACI will sign off on the

                         Common Collocation completion package.  This will
                         activate the monthly billing for leased space.  ACI may
                         then proceed with the installation of its equipment in
                         the Collocation space.  Once  ACI's equipment has been
                         installed and cable provided to the SPOT Frame, USWC
                         will complete all remaining work activities.  A second

8.     UNBUNDLED ACCESS/ELEMENTS

       8.1      GENERAL TERMS
                
                8.1.1    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 functions.
                         
                8.1.2    This Agreement provides for the provision of unbundled
                         Network Elements to ACI which ACI may connect or
                         combine for the purpose of offering finished retail
                         services. USWC will not combine USWC's unbundled
                         Network Elements to provide a finished service to ACI. 
                         USWC agrees, however, to offer finished retail services
                         to ACI for resale pursuant to the Resale section of
                         this Agreement.
                
                8.1.3    USWC will not restrict the types of telecommunications
                         services ACI may offer through unbundled elements, nor
                         will it restrict ACI from combining elements with any
                         technically compatible equipment ACI owns.  USWC will
                         provide ACI with  the same features, functions and
                         capabilities of a particular element that USWC provides
                         to itself, so that ACI can provide any
                         telecommunications services that can be offered by
                         means of the element. 

                                                                        PAGE 42

       8.2      DESCRIPTION OF UNBUNDLED ELEMENTS

                8.2.1    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 certain switching functions,
                         including those facilities that establish a temporary
                         transmission path between two other switches, but not
                         including the transport needed to complete the call. 
                         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.
                         
                8.2.2    Interoffice Transport
                         
                         USWC will provide access to dedicated transmission
                         facilities between its Central Offices or between such
                         offices and those of other carriers. 
                         
                8.2.3    Digital Cross Connect System.
                         
                         USWC will provide ACI with access to mutually agreed
                         upon digital cross-connect system (DCS) points.

                                                    point, will remain intact.
                         
                                   8.2.4.1.2        Basic Unbundled Loops are
                                                    available as a two-wire or
                                                    four-wire, point-to-point
                                                    configuration suitable for

                         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 Service
                         Management Systems (SMS) will be provided to ACI, via
                         the BFR process, to activate, modify, or update
                         information in the call related databases, equivalent
                         to the USWC access.
                                   
                9.1.2    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.  
                         
                9.1.3    CCSAC includes:

                                   connects the SWC to the USWC STP.  ACI may
                                   purchase this element or self-provision
                                   transport directly to the STP.  If ACI
                                   provides the link to the STP, it must
                                   purchase Collocation, an Expanded
                                   Interconnection Channel Termination at the
                                   STP location, and a direct link from the EICT
                                   to the STP Port.
                                   
                         9.1.3.3   STP Port - This element provides the
                                   switching function at the STP.  One STP Port
                                   is required for each DLT Link.  The Port
                                   provides interaction with the Service Control
                                   Point (SCP).  Port availability is limited.  
                                   
                         9.1.3.4   Multiplexing - Multiplexing may be required
                                   at either/both the SWC and/or Port.  The
                                   multiplexing options are the standard DS3 to
                                   DS1 and DS1 to DS0 requirements.
                                   
                9.1.4    Access to Advanced Intelligent Network (AIN) functions
                         is available only through the STP.
                         
                9.1.5    USWC will provide mediated access to SMS via the BFR
                         process, for the purpose of activating, modifying or
                         updating AIN service specification through its Service
                         Creation Environment (SCE) on an equivalent basis as
                         USWC provides to itself.  SMS allows ACI to provision,
                         modify, or update information in call related
                         databases.  Currently, the SCE process is predominantly
                         manual via a service center.

                         9.2.1.2   Until Permanent Number Portability is
                                   implemented by the industry pursuant to
                                   regulations issued by the FCC or the
                                   Commission, the Parties agree to provide
                                   Interim Number Portability ("INP") to each

                                   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
                                   end user 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.

                                   Database ("LIDB") listings for retained
                                   numbers as directed by ACI.  USWC will
                                   restrict or cancel calling cards associated
                                   with these forwarded numbers.  LIDB updates
                                   shall be completed by the Parties on the same
                                   business day each INP arrangement is
                                   activated.
                         
                         9.2.1.5   Upon request, USWC shall provide to ACI INP

                                   applicable tariffs.
                         
                         9.2.1.6   Where either Party has activated an entire
                                   NXX for a single end user, or activated a
                                   substantial portion 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 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.

                                   action will be taken immediately by the
                                   responsible Party.

                         9.3.2.3   Each Party will be responsible for the
                                   accuracy of its end user records.  Each Party
                                   specifically agrees to indemnify and hold
                                   harmless the other Party from any claims,
                                   damages, or suits related to the accuracy of
                                   end user data provided for inclusion in the
                                   E-911 Data Base.
                                   
                         9.3.2.4   For PSAP default routing purposes, ACI will
                                   establish separate trunks for the USWC
                                   selective router for each PSAP jurisdictional
                                   area it serves from a given switch.

                9.5.1    Scope.
       
                         9.5.1.1   White Pages Listings Service ("Listings")
                                   consists of USWC placing the names, addresses
                                   and telephone numbers of ACI's end users in
                                   USWC's listing database, based on end user
                                   information provided to USWC by ACI.  USWC is
                                   authorized to use Listings in Directory
                                   Assistance (DA) and as noted in paragraph
                                   9.5.1.4, below.
       
                         9.5.1.2   ACI will provide in standard, mechanized
                                   format, and USWC  will accept at no charge,
                                   one primary listing for each main telephone
                                   number belonging to ACI's end users.  Primary
                                   listings are as defined for USWC end users in
                                   USWC's general exchange tariffs.  ACI will be
                                   charged for premium and privacy listings,
                                   e.g., additional, foreign, cross reference,
                                   informational, etc., at USWC's general
                                   exchange listing tariff rates, less the
                                   wholesale discount.  If ACI utilizes Remote
                                   Call Forwarding for local number portability,
                                   ACI can list only one number without charge -
                                   either the end user's original telephone
                                   number or the ACI-assigned number.  The
                                   standard discounted rate for an additional
                                   listing applies to the other number. 

                                                                        PAGE 60

                         9.5.1.3   USWC will furnish ACI the Listings format
                                   specifications.  ACI may supply a maximum of
                                   one batch file daily, containing only
                                   Listings that completed on or prior to the
                                   transmission date.  USWC cannot 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
                                   ACI and USWC to determine time frames.  
                                   
                         9.5.1.4   ACI grants USWC a non-exclusive license to
                                   incorporate Listings information into its
                                   directory assistance database.  ACI hereby
                                   selects one of two options for USWC's use of
                                   Listings and dissemination of Listings to
                                   third parties.

       9.6      BUSY LINE VERIFY AND BUSY LINE INTERRUPT SERVICES

                9.6.1    Busy Line Verification ("BLV") is performed when one
                         Party's end user 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 end user initiating the BLV inquiry.  Only one
                         BLV attempt will be made per end user operator bureau
                         call, and a charge shall apply whether or not the
                         called party releases the line.
                         
                9.6.2    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 end user
                         initiating the BLVI request.  The operator bureau will
                         make only one BLVI attempt per end user operator
                         telephone call and the applicable charge applies
                         whether or not the called party releases the line.
                         
                9.6.3    The rates for Busy Line Verify and Busy Line Verify and
                         Interrupt are specified in Appendix A.
                         
                9.6.4    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.
                         
                9.6.5    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.

                         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.

10.    ACCESS TO OPERATIONAL SUPPORT SYSTEMS (OSS)

       USWC is developing a proposal for access to its Operational Support
       Systems (OSS) to meet the requirements of the FCC's 1st and 2nd Orders
       and to provide ACI with electronic interfaces for pre-ordering,
       ordering, demand repairs and billing functions for Plain Old Telephone
       Services (POTS).  These interfaces will also have the necessary
       mediation to protect the integrity of the network as well as allay any
       privacy concerns for end user information.  The components described in
       this section are conceptual in nature and will be subject to change as
       the implementation process proceeds.  There will be charges associated
       with the introduction of the interface and ongoing access to OSS
       operations which will include an initial access fee and an ongoing
       charge as described more fully below.

       10.1     OPERATIONAL SYSTEMS INTERFACES - INTERFACE IMPLEMENTATION
                TIMETABLE
       
                USWC's initial operational systems interfaces have been
                deployed and will support Pre-ordering, Ordering, Provisioning
                and Repair capabilities for POTS (non-design) services and
                Billing capabilities for most USWC product offerings. 
                Subsequent phases of the plan incorporate the capabilities to
                support designed services for Pre-ordering, Ordering,
                Provisioning, and Maintenance and Repair. The specific features
                and functions are not discussed in this Agreement.

                                                                        PAGE 66

       10.2     OSS INTERFACE DESIGN
       
                10.2.1   USWC will develop OSS interfaces using an electronic
                         gateway solution consistent with the design prescribed
                         by the FCC, Docket 96-98, FCC 96-325, paragraph 527. 
                         These gateways will act as a mediation or control point
                         between ACI's and USWC's Operations Systems. 
                         Additionally, these gateways will provide security for
                         the interface, protecting the integrity of the USWC
                         network and its databases.
                
                10.2.2   USWC proposes the use of the existing Electronic Data
                         Interchange ("EDI") standard for the transmission of
                         monthly local billing information.  EDI is an
                         established standard under the auspices of the American
                         National Standards Institute/Accredited Standards
                         Committee (ANSI/ASC) X12 Committee.  A proper subset of
                         this specification has been adopted by the
                         Telecommunications Industry Forum (TCIF) as the "811
                         Guidelines" specifically for the purposes of
                         telecommunications billing.  

                10.2.3   For the exchange of daily usage data, including third
                         party billed, collect, and card calls, USWC will use
                         the Bellcore EMR format for the records, using the
                         Network Data Mover ("NDM"), otherwise also known as the
                         Connect:Direct method to transmit the information to
                         carriers.

       10.3     ACCESSIBLE OSS FUNCTIONS
       
                10.3.1   Pre-ordering
                
                         "Pre-Ordering" refers to the set of activities whereby
                         a service representative dialogs with ACI in order to
                         obtain service availability.  In today's environment,
                         the pre-order process is performed in conjunction with
                         placing an order.  Packaged as a separate activity,
                         pre-order consists of the following functions:  verify
                         an address, check service availability, and return end
                         user service information.  USWC will provide on-line
                         capabilities to perform these functions.  These
                         functions are described as follows.
       
                         10.3.1.1  Address Verification 

                                   This transaction will verify the end user's
                                   address.
                                           
                                   If the address does not match USWC records,
                                   the AVR transaction will return "partial
                                   match" addresses and/or help as appropriate
                                   to assist ACI to properly identify the end
                                   user's address for verification.

                                                                        PAGE 67

<PAGE>

                                   Once the address is verified, the AVR
                                   transaction will return the valid address and
                                   the current status (working, non-working, or
                                   pending out) and the date the status was
                                   posted for each line at the address.
       
                                   If USWC does not have a record of the
                                   address, ACI will have to contact USWC to
                                   input the record before the order can be
                                   submitted.

                                   Note:
                                   
                                   10.3.1.1.1       No detailed facility
                                                    information (i.e., cable
                                                    pair) will be returned as
                                                    part of this transaction.

                                   10.3.1.1.2       Rural addresses will not be
                                                    supported.

                                   10.3.1.1.3       The AVQ/AVR transaction
                                                    attributes currently don't
                                                    reflect the attributes
                                                    required to support the
                                                    error scenarios.

                         10.3.1.2  Service Availability

                                   This transaction will return the list of
                                   products and services available for
                                   resale in the central office serving a
                                   particular end user address.  The
                                   USWC rates for the products and
                                   services will also be returned, but
                                   the ACI discount will not be applied.

                         10.3.1.3  End User Service Information Request

                                   Gives ACI the ability to request a listing of
                                   services and features USWC is currently
                                   providing to an end user and the rates USWC
                                   is charging for such services.

                         10.3.1.4  View/Update Service Query/Service Request
                                   Response

                                   Gives ACI the ability to view or update an
                                   existing Service Request (SR).
                                           
                         10.3.1.5  Store Service Request

                                   This transaction allows ACI to store a new or
                                   existing SR.
                                           
                                   This SR can be stored for the number of
                                   business days specified in USWC's methods and
                                   procedures before the SR must be submitted to
                                   USWC as a Work Order.

                                                                        PAGE 68

<PAGE>

                                   USWC will store the SR on-line until the
                                   associated Work Order is canceled by ACI or
                                   completed by USWC.
                                           
                10.3.2   Ordering

                         With the pre-ordering steps completed, the requisite
                         information will have been obtained from ACI and the
                         initiation of a service order can begin.  Submitting a
                         service order will result in the provisioning and
                         installation, if necessary, of an end user's service. 
                         The functional set required to order service is:  open
                         a service order, check facility availability, reserve
                         an appointment if technician work is required in the
                         field or at the end user's premises, reserve a
                         telephone number if appropriate, cancel a service
                         order, change a service order, send a firm order
                         confirmation, support for work order status queries,
                         and send notification of order completion.

                         10.3.2.1  Facility Availability

                                   For each new line requested, this transaction
                                   will indicate if existing facilities are
                                   available or if new facilities are required,
                                   and if a technician must be dispatched to
                                   provide the facilities requested at the end
                                   user's address.
                                   
                                   This transaction must be executed for any new
                                   line(s) requested.
                                           
                                   Note:

                                   10.3.2.1.1       This transaction does not
                                                    reserve facilities and does
                                                    not guarantee that
                                                    facilities will be
                                                    available when the work
                                                    order is submitted.

                                   10.3.2.1.2       USWC will automatically
                                                    execute this transaction as
                                                    part of order processing,
                                                    any time a new line or
                                                    transfer line is requested.

                         10.3.2.2  Telephone Number Availability

                                   Enables a telephone number (TN) to be
                                   assigned to a line.  ACI will be able to
                                   accept the TN or exchange the TN for two
                                   other TNs.  If the end user requests a
                                   specific number or a vanity number, ACI must
                                   call the USWC Number Assignment Center (NAC)
                                   and the request will be handled manually. 
                                   ACI will not have direct access to the
                                   telephone number assignment system.

                                                                        PAGE 69

<PAGE>

                         10.3.2.3  Exchange Telephone Numbers/Response

                                   Enables ACI to exchange the TN returned by
                                   the Telephone Number Availability Transaction
                                   for two more TNs.  ACI must select one of the
                                   three TNs to proceed with the Work Order.
                         
                         10.3.2.4  Return Telephone Numbers

                                   Enables ACI to reject the TNs returned by the
                                   Telephone Number Availability transaction and
                                   the TNs will be returned to the pool.

                         10.3.2.5  Telephone Number Accept

                                   Allows ACI to reserve one telephone number
                                   returned by the Telephone Number Availability
                                   transaction for a period of one (1) day so
                                   that the end user can be informed of the
                                   TN(s) prior to the actual submission of a
                                   Work Order.  The Work Order must be submitted
                                   before the TN expires, otherwise the TN will
                                   be returned to the available pool of TNs.

                         10.3.2.6  Appointment Availability

                                   Allows ACI to select an appointment from a
                                   calendar of available appointments.  ACI will
                                   not have direct access to the system but USWC
                                   will automatically execute this transaction
                                   after the Work Order has been submitted and a
                                   technician must be dispatched.

                         10.3.2.7  Appointment Reservation

                                   Enables ACI to reserve an available
                                   appointment after the appointment
                                   availability calendar has been returned to
                                   ACI by USWC.  USWC will return a confirmation
                                   number.
                                           
                         10.3.2.8  Work Order/Firm Order Completion

                                   The work order provides the information and
                                   actions required for USWC to provision
                                   products, services and features.  This
                                   transaction will also be used to cancel and
                                   change existing work orders.  The information
                                   contained in a work order identifies ACI, the
                                   end user desired due date, the service being
                                   requested, the order type (only change and
                                   migration to ACI), POA (Proof of
                                   Authorization), class of service, telephone
                                   number and additional information 

                                                                        PAGE 70

                                   needed to successfully provision the
                                   requested service to the end user.
                                           
                                   Once a work order is accepted by USWC, the
                                   assigned service order number will be
                                   returned to ACI.  This may not happen in real
                                   time.  ACI can then use the service order
                                   number to status the work order.  Firm Order
                                   Confirmation means that USWC has received the
                                   order and assigned an order number for
                                   tracking.  It does not mean that edits have
                                   been applied, so errors may still exist on
                                   the order.

                         10.3.2.9  Status Query/Response

                                   This transaction will allow ACI to obtain the
                                   status of a work order.  USWC will return the
                                   current status, remarks and due date for
                                   specified work order.
                                           
                                   Note:  This status request is issued by ACI
                                   on demand.  Real Time Order Completion and
                                   Jeopardy Notification is not proactively
                                   issued by USWC.

                         10.3.2.10 Order Completion Report
                         
                                   Provides ACI with a daily (Monday - Saturday)
                                   report, electronically, that identifies all
                                   work orders that were completed by USWC on
                                   that date.  This report is called the
                                   Co-Provider Completion Report.

                10.3.3.  Repair

                         Repair functions allow ACI to report trouble with
                         communications circuits and services provided by USWC. 
                         The functions, processes and systems used in repair are
                         based on a Trouble Report (TR), which is an electronic
                         document maintained in one or more Operations Systems. 
                         A TR contains information about the end user, the
                         trouble, the status of the work on the trouble and the
                         results of the investigation and resolution efforts.
                         These business processes have been summarized and will
                         be made available to ACI in the following functional
                         set:  open a trouble report, cancel a trouble report,
                         send notification of status change and close a trouble
                         report.

                         10.3.3.1  Verify Request

                                   This transaction will be used to verify

                                   Gives ACI the capability to open a TR with
                                   USWC.
                                   
                         10.3.3.3  Open Trouble Report Response

                                   Gives ACI the capability to the Open TR
                                   request and contains information about the TR
                                   that ACI needs to track or to convey to ACI's
                                   end user.

       10.4     BILLING INTERFACES
       
                USWC offers interfaces for the exchange of several types of
                billing data:
       
                         -         Monthly Billing Information,
                         -         Daily Usage Data,
                         -         Local Account Maintenance Report,
                         -         Centralized Message Distribution System
                                   (CMDS) messages, 
                         -         Routing of in-region intraLATA collect,
                                   calling card, and third number billed
                                   messages.

                10.4.1   Monthly Billing Information

                         Includes all connectivity charges, credits, and
                         adjustments related to network elements and
                         USWC-provided local service. 

                10.4.2   Daily Usage Data 
                
                         The accumulated set of call information for a given day
                         as captured, or "recorded," by the network switches. 
                         USWC will 

                                                                        PAGE 72

<PAGE>

                         provide this data to ACI with the same level of
                         precision and accuracy it provides itself. Such
                         precision cannot and will not exceed the current
                         capabilities of the software in the switches today. 

                10.4.3   Local Account Maintenance Report

                         The list of phone numbers to which the carrier is no
                         longer providing service since the last report. 

                10.4.4   Centralized Message Distribution System ("CMDS")

                         Distribution of CMDS messages for ACI end users.  

                10.4.5   Routing of In-region IntraLATA Collect, Calling Card,
                         and Third Number Billed Messages
                
                         USWC will distribute in-region intraLATA collect,
                         calling card, and third number billed messages to ACI
                         and exchange with other Co-Providers operating in
                         region in a manner consistent with existing
                         inter-company processing agreements.  Whenever the
                         daily usage information is transmitted to a carrier, it
                         will contain the records for these types of calls as
                         well.

       10.5     Compensation
                
                10.5.1   Compensation for OSS access will consist of an initial
                         access fee which will be determined based on the
                         specific access engineered and implemented for ACI and
                         is a function of the numbers of ACI business office and
                         repair service representatives accessing the system. 
                         The fee will include costs for hardware (if purchased
                         through USWC), software (which must be purchased
                         through USWC), telecommunications links and labor
                         incurred to establish the interfaces to USWC's OSS for
                         ACI.  The costs will be substantiated by purchasing
                         invoices for the communications and computing hardware
                         and software, and by time reports for the labor
                         expended in their design and implementation.  Labor
                         will be billed at the prevailing rates for contract
                         labor for similar services.  USWC will bill ACI in a
                         nondiscriminatory manner for OSS based on approved
                         prices.  USWC will work cooperatively with ACI to
                         establish a payment schedule for true-up of OSS prices
                         from the time OSS is established to the time OSS is
                         approved.
                         
                10.5.2   The ongoing charge will be billed at a rate to be
                         specified by the Commission at the completion of an
                         appropriate cost study hearing.

                                                                        PAGE 73

       11.1     DESCRIPTION

                11.1.1   USWC Basic Exchange Telecommunications Service and
                         Basic Exchange Switched Features (as defined in Section

                         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 applicable discounts.

                11.1.2   The Parties agree that, at this time, certain USWC
                         services are not available for resale under this
                         Agreement and certain other USWC services are available
                         for resale but at no discount, as identified in
                         Appendix A or in individual state tariffs.  The
                         availability of services and applicable discounts
                         identified in Appendix A or in individual tariffs are
                         subject to change pursuant to the Rates and Charges
                         sub-section of this Resale section.

                11.1.3   The scope of restrictions in 11.1.1 and 11.1.2 are
                         subject to the state rules and decisions.

       11.2     SCOPE

                11.2.1   Basic Exchange Telecommunications Service, Basic
                         Exchange Switched Features and IntraLATA Toll may be
                         resold only for their intended or disclosed use and
                         only to the same class of end user to which USWC sells
                         such services e.g., residence service may not be resold
                         to business end users.

                11.2.2   USWC shall provide to ACI services for resale that are
                         equal in quality, subject to the same conditions
                         (including the conditions in USWC's effective tariffs),
                         within provisioning time intervals that are
                         substantially equal to the intervals USWC provides
                         these services to others, including its end users, and
                         in accordance with any applicable state Commission
                         service quality standards, including standards a state
                         Commission may impose pursuant to Section 252 (e)(3) of
                         the Act.

       11.3     ORDERING AND MAINTENANCE

                11.3.1   ACI, or ACI'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.  ACI shall
                         make it clear to its end users that

                                                                        PAGE 74

                         they are end users of ACI for resold services.  ACI's
                         end users contacting USWC will be instructed to contact
                         ACI; however, nothing in this Agreement, except as
                         provided below, shall be deemed to prohibit USWC from
                         discussing its products and services with ACI's end
                         users who call USWC for any reason.

                11.3.2   ACI 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 ACI.  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 the end
                         user effective with the disconnection.  If USWC is not
                         the local service provider, USWC will issue a bill to
                         ACI for that portion of the service provided to ACI
                         should ACI's end user, a new service provider, or ACI
                         request service be discontinued to the end user.  USWC
                         will notify ACI by FAX, OSS, or other processes when an
                         end user moves to another service provider.  USWC will
                         not provide ACI with the name of the other Reseller or
                         service provider selected by the end user.  The Parties
                         agree that they will not transfer to each other their
                         respective end users whose accounts are in arrears.
                         The Parties further agree that they will work
                         cooperatively together to develop the standards and
                         processes applicable to the transfer of such accounts.

                11.3.3   ACI shall provide USWC and USWC shall provide ACI with
                         points of contact for order entry, problem resolution
                         and repair of the resold services.

                11.3.4   Prior to placing orders on behalf of the end user, ACI
                         shall be responsible for obtaining and have in its
                         possession Proof of Authorization ("POA").  POA shall
                         consist of documentation acceptable to USWC of the end
                         user's selection of ACI.  Such selection may be
                         obtained in the following ways:

                         11.3.4.1  The end user's written Letter of
                                   Authorization or LOA.

                         11.3.4.2  The end user's electronic authorization by
                                   use of an 800 number,

                         11.3.4.3  The end user's oral authorization verified by
                                   an independent third party (with third party
                                   verification as POA).

                         11.3.4.4  A prepaid returnable postcard supplied by ACI
                                   which has been signed and returned by end
                                   user.  ACI will wait 

                                                                        PAGE 75

                                   fourteen (14) business days after mailing
                                   the postcard before placing an order to 
                                   change.

                11.3.5   ACI shall make POAs available to USWC upon request.
                         Prior to placing orders that will disconnect a line
                         from another Reseller's account ACI is responsible for
                         obtaining all information needed to process the
                         disconnect order and re-establish the service on behalf
                         of the end user.  Should an end user dispute or a
                         discrepancy arise regarding the authority of ACI to act
                         on behalf of the end user, ACI 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 ACI's written
                         evidence of its authority, USWC shall honor the
                         designation of the end user and change the end user
                         back to the previous service provider.  If ACI does not
                         provide the POA within three (3) business days, or if
                         the end user disputes the authority of the POA, then
                         the ACI must, by the end of the third business day:

                         11.3.5.1  notify USWC to change the end user back to
                                   the previous Reseller or service provider,
                                   and

                         11.3.5.2  provide any end user information and billing
                                   records ACI has obtained relating to the end
                                   user to the previous Reseller, and

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

                         11.3.5.4  remit to USWC a charge of $100.00  ("slamming
                                   charge") as compensation for the change back
                                   to the previous Reseller or service provider.

                11.3.6   If an end user is switched from ACI back to USWC and
                         there is a dispute or discrepancy with respect to such
                         change in service provider, ACI may request to see a
                         copy of the POA which USWC has obtained from the end
                         user to effectuate a return to USWC as the end user's
                         service provider.  If USWC is unable to produce a POA
                         within three (3) business days, USWC shall change the
                         end user back to ACI (or other previous Reseller)
                         without imposition of any Customer Transfer Charge.

                11.3.7   ACI 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.

                11.3.8   When end users switch from USWC to ACI, or to ACI from
                         any other Reseller, such end users shall be permitted
                         to retain their

                                                                        PAGE 76

                         current telephone numbers if they so desire and do not
                         change their service address to an address served by a
                         different central office.  USWC shall take no action to
                         prevent ACI end users from retaining their current
                         telephone numbers.

                11.3.9   ACI and USWC will employ the procedures for handling
                         misdirected repair calls as specified in the
                         Coordinated Repair Calls section of this Agreement.

       11.4     ACI RESPONSIBILITIES

                11.4.1   ACI must send USWC complete and accurate end-user
                         listing information for Directory Assistance, Directory
                         Listings, and 911 Emergency Services using USWC's
                         resale order form and process.  ACI 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 ACI.

                11.4.2   ACI may not reserve blocks of USWC telephone numbers,
                         except as allowed by tariffs.

                11.4.3   ACI is liable for all fraud associated with service to
                         its end-users and accounts.  USWC takes no
                         responsibility, will not investigate, and will make no
                         adjustments to ACI's account in cases of fraud unless
                         such fraud is the result of any intentional act or
                         gross negligence of USWC.  Notwithstanding the above,
                         if USWC becomes aware of potential fraud with respect
                         to ACI's accounts, USWC will promptly inform ACI and,
                         at the direction of ACI, take reasonable action to
                         mitigate the fraud where such action is possible.

                11.4.4   In accordance with the Act, ACI will indicate the date
                         it will offer to residential and business subscribers
                         telephone exchange services.  ACI will provide a three
                         year forecast within ninety (90) business days of
                         signing this Agreement.  During the first year of the
                         term of this Agreement, the forecast shall be updated
                         and provided to USWC on a quarterly basis.  Thereafter,
                         during the term of this Agreement ACI will provide
                         updated forecasts from time to time, as requested by
                         USWC.  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
                         -         ACI's anticipated order volume
                         -         ACI's key contact personnel

                                                                        PAGE 77

<PAGE>

                         The information provided pursuant to this paragraph
                         shall be considered Proprietary Information under the
                         Nondisclosure section of this Agreement.

                11.4.5   In the event USWC terminates the provisioning of any
                         resold services to ACI for any reason, including
                         disconnection of ACI for failure to make payment as
                         required herein, ACI 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 to ACI's end users.  USWC will
                         provide notice to ACI of USWC's termination of a resold
                         service on a timely basis consistent with Commission
                         rules and notice requirements.

       11.5     RATES AND CHARGES

                11.5.1   Resold services as listed in Appendix A are available
                         for resale at the applicable discount percentage or
                         rate per minute set forth in Appendix A or at the
                         retail tariff rates for services available for resale
                         but excluded from the wholesale pricing arrangement in
                         this Agreement.

                         However, state Commissions may do any of the following
                         (collectively referred to hereinafter as "Order")
                         during the term of this Agreement:

                         -         establish wholesale discount rates through
                                   decisions in arbitration, interconnection
                                   and/or resale cost proceedings;
                         -         establish other recurring and nonrecurring
                                   rates related to resale, including but not
                                   limited to Customer Transfer Charges and
                                   Slamming Charges ("Other Resale Charges");
                                   and
                         -         order that certain services be made available
                                   for resale at specified wholesale discount
                                   rates.

                         If a state Commission orders services to be available
                         for resale, the Parties agree that they will, on a
                         state-by-state basis, revise Appendix A to incorporate
                         the services determined by such Order into this
                         Agreement, effective on the date ordered by a
                         Commission.  When a state Commission, through a
                         decision in arbitration, identifies services that must
                         be available for resale at wholesale discount rates,
                         such decision shall be deemed to have defined that such
                         services are generally available to Resellers in that
                         state.  If a state Commission establishes wholesale
                         discount rates and Other Resale Charges to be made
                         generally available to Resellers or establishes a
                         resale tariff, the Parties agree that they will, on a
                         state-by-state basis, revise Appendix A to incorporate

                                                                        PAGE 78

<PAGE>

                         such wholesale discount rates and/or Other Resale
                         Charges into this Agreement effective on the date
                         ordered by a Commission; provided, however, that USWC
                         shall have a reasonable time to implement system or
                         other changes necessary to bill the Commission ordered
                         rates or charges.

                         The rates for those resold services initially included
                         in the wholesale pricing arrangement under this
                         Agreement shall be subject to true-up to the wholesale
                         discount rates established by a Commission Order making
                         such rates generally available to Resellers or
                         established by a resale tariff, retroactively to the
                         effective date of this Agreement. Any true-up shall be
                         on a service-by-service basis if wholesale discount
                         rates are established by a Commission on such a basis.

                         Services excluded from the wholesale pricing
                         arrangement under this Agreement as identified in
                         Appendix A, shall be made available on a going forward
                         basis from the date of a Commission Order that orders
                         such services be made generally available to any
                         Reseller in the state where such a Commission Order is
                         issued.  Such services shall be available at the
                         discount rate applicable to basic exchange business
                         service identified in Appendix A; provided, however,
                         that when a Commission Order establishes wholesale
                         discount rates for such services as generally available
                         to Resellers, Appendix A shall be revised to
                         incorporate the wholesale discount rates generally
                         available to Resellers.

                         If a state Commission fails to issue such an Order or
                         make effective such a tariff by the end of the first
                         year of this Agreement, either USWC or ACI may elect to
                         renegotiate this Section of the Agreement.

                11.5.2   If the resold services are purchased pursuant to
                         Tariffs and the Tariff rates change, charges billed to
                         ACI for such services will be based upon the new Tariff
                         rates less the applicable wholesale discount as agreed
                         to herein or established by resale Tariff.  The new
                         rate will be effective upon the Tariff effective date.

                11.5.3   A Customer Transfer Charge (CTC) as specified in
                         Appendix A applies when transferring any existing
                         account or lines to ACI. Tariffed, non-recurring
                         charges will apply to new installations.

                11.5.4   A Subscriber Line Charge (SLC) will continue to be paid
                         by ACI 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.

                                                                        PAGE 79

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

                11.5.6   ACI agrees to pay USWC when its end user activates any
                         services or features that are billed on a per use or
                         per activation basis subject to the applicable discount
                         in Appendix A as such may be amended pursuant to
                         Section 11.5.1 above (e.g., continuous redial, last
                         call return, call back calling, call trace, etc.).

                11.5.7   Resold services are available only where facilities
                         currently exist and are capable of providing such
                         services without construction of additional facilities
                         or enhancement of existing facilities; provided
                         however, that any loop facilities serving Co-Provider's
                         end-user(s) at the time of the end-user(s) switch to
                         Co-Provider shall be considered "existing" and
                         "capable" to allow Co-Provider to offer resold services
                         to that end-user(s).  However, if ACI requests that
                         facilities be constructed or enhanced to provide resold
                         services, USWC will review such requests on a
                         case-by-case basis and determine, in its sole
                         discretion, if it is economically feasible for USWC to
                         build or enhance facilities.  If USWC decides to build
                         or enhance the requested facilities, USWC will develop
                         and provide to ACI a price quote for the construction.
                         If the quote is accepted, ACI will be billed the quoted
                         price and construction will commence after receipt of
                         payment.

                11.5.8.  Nonrecurring charges will not be discounted and will be
                         billed at the applicable Tariff rates.

                11.5.9   As a part of the resold line, USWC provides and ACI
                         accepts, at this time, operator services, directory
                         assistance, and intraLATA long distance with standard
                         USWC branding. ACI is not permitted to alter the
                         branding of these services in any manner when the
                         services are a part of the resold line without the
                         prior written approval of USWC.  However, at the
                         request of ACI and where technically feasible, USWC
                         will rebrand operator services and directory assistance
                         in ACI's name, provided the costs associated with such
                         rebranding are paid by ACI.

       11.6     COLLATERAL AND TRAINING

                The Parties will jointly develop procedures regarding ACI's use
                of USWC's retail product training materials.  Except for any
                rights granted by USWC to ACI for the use or copying of product
                training material, product training provided under this
                Agreement shall be considered "Proprietary Information" as
                described in this Agreement, and shall be subject to the terms
                and conditions specified therein.

                                                                        PAGE 80

       11.7     DIRECTORY LISTINGS

                USWC will accept at no charge one primary listing for each main
                telephone number belonging to ACI's end user based on end user
                information provided to USWC by ACI.  USWC will place ACI'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 the Ancillary Services and Arrangements section of
                this Agreement.

       11.8     BILLING

                11.8.1.  USWC shall bill ACI and ACI is responsible for all
                         applicable charges for the resold services as provided
                         herein.  ACI shall also be responsible for all tariffed
                         charges and charges separately identified in this
                         Agreement associated with services that ACI resells to
                         an end user under this Agreement.

                11.8.2   USWC shall provide ACI, on a monthly basis, within 7-10
                         business days of the last day of the most recent
                         billing period, in an agreed upon standard electronic
                         billing format, billing information including (1) a
                         summary bill, and (2) individual end user sub-account
                         information consistent with the samples provided to ACI
                         for ACI to render end user bills indicating all
                         recurring and nonrecurring charges associated with each
                         individual end user's account for the most recent
                         billing period.

       11.9     DEPOSIT

                11.9.1   USWC may require ACI 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 business 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.

                11.9.2   When the service is terminated, or when ACI has
                         established satisfactory credit, the amount of the
                         initial or additional deposit, with any interest due as
                         set forth in applicable Tariffs, will, at ACI's option,
                         either be credited to ACI'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.  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.

                                                                        PAGE 81

       11.10    PAYMENT

                11.10.1  Amounts payable under this Resale Section are due and
                         payable within thirty (30) calendar days after the bill
                         date of USWC's invoice.  During the initial three
                         billing cycles of this Agreement, ACI and USWC agree
                         that undisputed amounts shall be paid as provided
                         herein.  ACI and USWC further agree that, during said
                         three billing cycle period, they will cooperate to
                         resolve amounts in dispute or billing process issues in
                         a timely manner but no later than sixty (60) business
                         days after the bill date of USWC's invoice or
                         identification and notice of the billing process issue.
                         Disputed amounts will be paid within thirty (30)
                         business days following resolution of the dispute.

                11.10.2  After the three (3) month period outlined above, ACI
                         will pay the bill in full within 30 calendar days after
                         the bill date of the invoice.  Billing disputes will be
                         processed and jointly resolved.  Any disputed amounts
                         that USWC remits to ACI will be credited on the next
                         billing cycle including an interest credit of 1.5% per
                         month compounded.

                11.10.3  A late payment charge of 1.5% applies to all billed
                         balances which are not paid by 30 calendar days after
                         the bill date shown on the invoice. USWC agrees,
                         however, that the application of this provision will be
                         suspended for the initial three billing cycles of this
                         Agreement and will not apply to amounts billed during
                         those three cycles.

                11.10.4  USWC may discontinue processing orders for the failure
                         by ACI to make full payment for the resold services
                         provided under this Agreement within thirty (30)
                         calendar days of the due date on ACI's bill.  USWC
                         agrees, however, that the application of this provision
                         will be suspended for the initial three billing cycles
                         of this Agreement and will not apply to amounts billed
                         during those three cycles.

                11.10.5  USWC may disconnect for the failure by ACI to make full
                         payment for the resold services provided under this
                         Agreement within sixty (60) calendar days of the due
                         date on ACI's bill.  ACI will pay the Tariff charge
                         required to reconnect each end user line disconnected
                         pursuant to this paragraph.  USWC agrees, however, that
                         the application of this provision will be suspended for
                         the initial three billing cycles of this Agreement and
                         will not apply to amounts billed during those three
                         cycles.

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

                                                                        PAGE 82

<PAGE>

                11.10.7  USWC shall credit ACI's account the amount due for any
                         trouble or out-of-service conditions in the same manner
                         that USWC credits the accounts of its own end users and
                         pursuant to any applicable provisions in USWC's
                         Tariffs.  USWC shall reflect the amount of such credits
                         on an individual end user telephone number basis in the
                         billing information USWC provides ACI.

                11.10.8  In the event billing disputes relate to service quality
                         issues, the dispute shall be referred to the USWC
                         account executive assigned to ACI who will evaluate the
                         facts and circumstances of the service quality issues
                         and will work with ACI to resolve the dispute.


12.    ACCESS TO TELEPHONE NUMBERS

       12.1     NUMBER RESOURCES ARRANGEMENTS.

                12.1.1   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).

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

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

                12.1.4   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.

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

                                                                        PAGE 83

                12.1.6   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 ACI in accordance with national guidelines at
                         no charge.

                12.1.7   Each Party is responsible for administering NXX codes
                         assigned to it.  Each Party is responsible for
                         obtaining 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.

13.    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.

14.    U S WEST DEX ISSUES

       USWC and ACI 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 ACI and directory
       publishers, including U S WEST Dex.  USWC acknowledges that ACI may
       request USWC to facilitate discussions between ACI and U S WEST Dex.

15.    ACCESS TO DATABASES

       In accordance with Section 271 of the Act, USWC shall provide ACI with
       interfaces to access USWC's databases and associated signaling necessary
       for the routing and completion of ACI traffic.  Except where otherwise
       specified, access to such databases, and the appropriate interfaces,
       shall be requested by ACI via a Bona Fide Request.

16.    NOTICE OF CHANGES

       If a Party makes a change in its network which it believes will
       materially 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.

17.    REFERRAL ANNOUNCEMENT

       When an end user changes from USWC to ACI, or from ACI to USWC, and does
       not retain its original main/listed 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.

                                                                        PAGE 84

<PAGE>

       This announcement will provide details on the new number that must be
       dialed to reach this end user.

18.    COORDINATED REPAIR CALLS

       18.1     ACI and USWC will employ the following procedures for handling
                misdirected repair calls;

                18.1.1   ACI and USWC will provide their respective end users
                         with the correct telephone numbers to call for access
                         to their respective repair bureaus.

                18.1.2   End users of ACI shall be instructed to report all
                         cases of trouble to ACI.  End users of USWC shall be
                         instructed to report all cases of trouble to USWC.

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

                18.1.4   ACI and USWC will provide their respective repair
                         contact numbers to one another on a reciprocal basis.

                18.1.5   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 end users to market services.
                         Either Party may respond with accurate information in
                         answering end user questions.


19.    BONA FIDE REQUEST PROCESS

       19.1     Any request for Interconnection or access to an unbundled
                Network Element that is not already available as described
                herein shall be treated as a Bona Fide Request (BFR).  USWC
                shall use the BFR Process to determine the terms and timetable
                for providing the requested Interconnection or access to
                unbundled Network Elements, if available, and the technical
                feasibility of new/different points of Interconnection.  USWC
                will administer the BFR Process in a non-discriminatory manner.

       19.2     A BFR shall be submitted in writing and on the appropriate USWC
                form for BFRs.  The Parties will work together to prepare the
                BFR form.  The form will request, and ACI will need to provide,
                at a minimum: (a) a technical description of each requested
                Network Element or new/different points of 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; (e) the quantity requested; (f) the
                specific location requested; (g) if the requested unbundled
                Network Element is a

                                                                        PAGE 85

<PAGE>

                proprietary element as specified in Section 251(d)(2) of the
                Act, ACI must submit documentation that demonstrates that
                access to such Network Element is necessary, that the failure
                to provide access to such Network Element would impair the
                ability of ACI to provide the services that it seeks to offer,
                and that ACI's ability to compete would be significantly
                impaired or thwarted without access to such requested
                proprietary element; and (h) if the requested unbundled Network
                Element is a non-proprietary element as specified in Section
                251(d)(2) of the Act, ACI must submit documentation that
                demonstrates that denial of access to such unbundled
                non-proprietary Network Element would decrease the quality or
                increase the cost of the service sought to be offered by ACI.

       19.3     Within two (2) business days of its receipt, USWC shall
                acknowledge receipt of the BFR and in such acknowledgment
                advise ACI of missing information, if any, necessary to process
                the BFR.  Thereafter, USWC shall promptly advise ACI of the
                need for any additional information that will facilitate the
                analysis of the BFR.  The Parties may mutually agree to
                conference calls or face-to-face meetings at mutually agreeable
                times to discuss information necessary to process the BFR.
                USWC will consider any previous BFRs in the evaluation of the
                BFR in progress to make best efforts to shorten response times
                and, to the extent possible, avoid duplicate work.  USWC will
                provide BFR status to ACI every ten (10) business days.

       19.4     Within 30 calendar days of its receipt of the BFR and all
                information necessary to process it, USWC shall provide to ACI
                a preliminary analysis of the BFR.  The preliminary analysis
                shall specify USWC's conclusions as to whether or not the
                requested Interconnection or access to an unbundled Network
                Element complies with the unbundling requirements set forth
                above.

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

                19.4.2   If USWC determines during the thirty day period that
                         the BFR qualifies under the Act, it shall notify ACI in
                         writing of such determination within ten calendar days.

                19.4.3   As soon as feasible, but in any case within 90 calendar
                         days after USWC notifies ACI that the BFR qualifies
                         under the Act, USWC shall provide to ACI a BFR quote.
                         The BFR quote 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 development costs and
                         construction charges of

                                                                        PAGE 86
<PAGE>

                         the Interconnection or the Network Elements and any
                         minimum volume and term commitments required.
                         Additionally, USWC shall notify ACI of any laboratory
                         testing, field testing, or joint field testing that may
                         be required for technical feasibility.  As needed, the
                         Parties will mutually agree to test schedules.  Testing
                         costs will be identified.

       19.5     A BFR quote will remain valid for thirty (30) calendar days.
                Minimum volume and term commitments may be applicable.  Upon
                thirty (30) calendar days, ACI must advise USWC, in writing, to
                cancel, proceed, or invoke dispute resolution as described in
                this Agreement.

       19.6     ACI may cancel the BFR request any time.  USWC reserves the
                right to bill reasonable cancellation charges.  ACI will pay
                USWC reasonable development costs incurred in providing the
                Interconnection or Network Element to the extent that those
                development costs are not otherwise amortized.  Volume and term
                commitments will be considered.

       19.7     If either Party believes that the other Party is not
                requesting, negotiating or processing any BFR in good faith, or
                disputes a determination, or quoted price or cost, it may seek
                arbitration pursuant to the Dispute Resolution provision of
                this Agreement.


20.    AUDIT PROCESS

       20.1     "Audit" shall mean the comprehensive review of:

                20.1.1   Data used in the billing process for services performed
                         and facilities provided under this Agreement; and

                20.1.2   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.

       20.2     The data referred to 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:

                20.2.1   Either Party may request to perform an Audit.

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

                                                                        PAGE 87

<PAGE>

                20.2.3   The Audit shall occur during normal business hours.

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

                20.2.5   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.

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

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

                20.2.8   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.

                20.2.9   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.

                20.2.10  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.

                20.2.11  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).

       20.3     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, ACI 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 88

<PAGE>

21.    AUDIOTEXT AND MASS ANNOUNCEMENT SERVICES

       21.1     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,
                if available, 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.

       21.2     ACI and USWC will work together in good faith to negotiate and
                execute the agreement for billing and compensation for these
                services.  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.

       21.3     Until such time that such an agreement is executed, ACI may
                choose to block such calls, or ACI 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.

                21.3.1   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.

                21.3.2   BILLING AND COLLECTION COMPENSATION.

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


22.    LOCAL INTERCONNECTION DATA EXCHANGE FOR BILLING

       22.1     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
                                                                        PAGE 89

<PAGE>

                Parties agree to utilize, where possible and appropriate,
                existing accounting and settlement systems to bill, exchange
                records and settle revenue.

       22.2     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.

       22.3     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.

       22.4     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 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.

       22.5     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.


23.    CONSTRUCTION CHARGES

       23.1     All rates, charges and initial service periods specified in
                this Agreement contemplate the provision of network
                Interconnection services and access to Network Elements to the
                extent existing facilities are available.  Except for
                modifications to existing facilities necessary to accommodate
                Interconnection and access to Network Elements specifically
                provided for in this Agreement, USWC will consider requests to
                build additional or further facilities for network
                Interconnection and access to Network Elements as described in
                this Section.

       23.2     Resale

                Construction charges associated with the resale of services
                will be applied in the same manner that construction charges
                apply to USWC's retail end users. Contracts may be negotiated
                on an individual case basis when construction is required for
                large retail or resale customers.

       23.3     LIS and Interoffice Transport

                To the extent that USWC constructs facilities for LIS services
                and/or interoffice transport, ACI will provide USWC with a
                forecast of interoffice trunks and switch


                                                                        PAGE 90

<PAGE>

                ports.  USWC will perform a validated traffic engineering
                estimate based on the forecasted demand and will then negotiate
                an agreed upon quantity of interoffice trunks and switch ports
                with ACI before constructing facilities.  If ACI's forecasted
                quantity exceeds USWC's validated traffic engineering estimate,
                and if USWC finds it necessary to construct added facilities,
                then construction charges will apply to the exceeded quantity.
                USWC will track utilization of trunks, and when minimum trunk
                utilization requirements are not met, a recurring charge will
                apply for all unused trunks below the minimum utilization
                level.

       23.4     Unbundled Network Elements

                USWC will conduct an individual financial assessment of any
                request which requires construction of network capacity,
                facilities, or space for access to or use of unbundled Network
                Elements.  If USWC constructs to fulfill ACI's request for
                unbundled Network Elements, USWC will bid this construction on
                a case-by-case basis.  USWC will charge for the construction
                through non-recurring charges and a term agreement for the
                remaining recurring charge.

       23.5     All necessary construction will be undertaken at the discretion
                of USWC, consistent with budgetary responsibilities,
                consideration for the impact on the general body of end users,
                and without discrimination among the various carriers.

       23.6     A quote for ACI's portion of a specific job will be provided to
                ACI.  The quote will be in writing and will be binding for
                ninety (90) business days after the issue date.  When accepted,
                ACI will be billed the quoted price and construction will
                commence after receipt of payment.  If ACI chooses not to have
                USWC construct the facilities, USWC reserves the right to bill
                ACI for the expense incurred for producing the engineered job
                design.

       23.7     In the event a construction charge is applicable, ACI's service
                application date will become the date upon which USWC receives
                the required payment.


24.    SERVICE PERFORMANCE RESULTS

       24.1     USWC agrees to provide to ACI the same level of service that
                USWC provides to itself and/or its affiliates as determined by
                measuring and comparing a statistically significant number of
                activities listed below.

                24.1.1   For those services procured by ACI and unless otherwise
                         noted below, USWC shall measure its results and those
                         of its affiliates as a percentage.  USWC shall also
                         measure the percentage results of ACI.

                         ACI agrees to measure its performance related to these
                         performance indicators in providing service to USWC.

                                                                        PAGE 91

<PAGE>

                24.1.2   In some instances, USWC may not provide the listed
                         service to itself or its affiliates.  If USWC does not
                         provide a statistically significant number of a listed
                         activity for itself or its affiliates, USWC will
                         provide data which will allow comparison between ACI's
                         performance results and the average performance results
                         of the same performance indicator for a statistically
                         significant number of total activities provided to all
                         other Co-Providers within the state in which the
                         service was provided.

                24.1.3   In no event shall percentage results be provided if the
                         number of measured activities is less than a
                         statistically significant universe of fewer than sixty
                         (60) activities during the time period of measurement.

                24.1.4   The list of performance indicators to be measured are
                         as follows:

       24.2     Failure to Meet the Service Standard.  If during a specified
                review period, the performing Party fails to deliver the same
                level of service that it provides to itself, such Party will
                use its best efforts to meet the service standard for the next
                specified review period.  If the performing Party fails to meet
                the service standard for two consecutive periods, the Parties
                agree, in good faith, to attempt to resolve such issues through
                negotiation or pursuant to the Dispute Resolution section of
                this Agreement.  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.

       24.3     The performing Party's failure to meet the service standard
                cannot be as a result, directly or indirectly, of a Delaying
                Event.  A "Delaying Event" means (a) a failure by the receiving
                Party 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 the receiving Party or (c) any Force
                Majeure Event.  If a Delaying Event prevents the performing
                Party from performing a measured activity, then such measured
                activity shall be excluded from the calculation of the
                performing Party's compliance with the service standard.

       24.4     Records.  Each Party shall maintain complete and accurate
                records, for the specified review period of its performance
                under this Agreement for each measured activity and its
                compliance with the service standard.  Each Party shall provide
                to the other such records in a self-reporting format.  Such
                records shall be in the format kept in the performing Party's
                ordinary course of business.  The Parties agree that such
                records shall be deemed "Proprietary Information".

       24.5     Cost Recovery.  Each Party reserves the right to recover the
                costs associated with the creation of the above reports and
                standards through a future proceeding before a regulatory body.
                Such a proceeding may address a wide range of implementation
                costs not otherwise recovered through charges established
                herein.

26.    MISCELLANEOUS TERMS

       26.1     GENERAL PROVISIONS

                26.1.1   Each Party shall use its best efforts to comply with
                         the Implementation Schedule.

                26.1.2   The Parties are each solely responsible for
                         participation in and compliance with national network

                         calls, and any other services related to this
                         Agreement.

       26.2     TERM OF AGREEMENT

                This Agreement shall become effective upon Commission approval,
                pursuant to Sections 251 and 252 of the Act, shall terminate on
                ________ __, 19__, and shall be binding upon the Parties during
                that term, notwithstanding Section 252(i) of the Act.  The
                Parties agree to commence negotiations on a new agreement no
                later than 135 calendar days prior to the termination date
                specified above; provided that ACI, consistent with Section

       26.3     PAYMENT

                26.3.1   Amounts payable under this Agreement are due and
                         payable within thirty (30) business days after the date
                         of invoice.

                26.3.2   Except as specified in the Resale section of this
                         Agreement or elsewhere in this Agreement, any amount
                         due and not paid by the 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.

                26.3.3   Should ACI dispute any portion of the monthly billing
                         under this Agreement, ACI will notify USWC in writing
                         within thirty (30) business days of the receipt of such
                         billing, identifying the amount and details of such
                         dispute.  ACI shall pay all amounts due.  Both ACI and
                         USWC agree to expedite the investigation of any
                         disputed amounts in an effort to resolve and settle the
                         dispute prior to initiating any other rights or
                         remedies.  Should the dispute be found in ACI's favor,
                         USWC will reimburse ACI the resolved amount plus
                         interest from the date of payment at the late payment
                         factor of the Intrastate Access Service Tariffs,
                         General Regulations for the state in which the service
                         is rendered.

                26.3.4   If ACI is repeatedly delinquent in making its payments,
                         USWC may, in its sole discretion, require a deposit to
                         be held as security for the payment of charges.
                         "Repeatedly delinquent" means being thirty (30)
                         business days or more delinquent for three (3)
                         consecutive months.  The deposit may not exceed the
                         estimated total monthly charges for a two (2) month
                         period.  The deposit may be a cash deposit, a letter of
                         credit with terms and conditions acceptable to USWC in
                         its sole discretion, or some other form of mutually
                         acceptable security.

                26.3.5   Interest will be paid on cash deposits at the rate
                         applying to deposits under applicable Commission rules,
                         regulations, or Tariffs.  Cash deposits and accrued
                         interest will be credited to ACI's account or refunded,
                         as appropriate, upon the earlier of the termination of
                         this Agreement or one full year of timely payments in
                         full by ACI.  The fact that a deposit has been made
                         does not relieve ACI from any requirements of this
                         Agreement.

                                                                        PAGE 96

       26.4     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.

       26.5     FORCE MAJEURE

                Neither Party shall be liable for any delay or failure in
                performance of any part of this Agreement from any cause beyond
                its control and without its fault or negligence including,
                without limitation, acts of nature, acts of civil or military
                authority, government regulations, embargoes, epidemics,
                terrorist acts, riots, insurrections, fires, explosions,
                earthquakes, nuclear accidents, floods, work stoppages,
                equipment failure, power blackouts, volcanic action, other
                major environmental disturbances, unusually severe weather
                conditions, inability to secure products or services of other
                persons or transportation facilities or acts or omissions of
                transportation carriers (collectively, a "Force Majeure
                Event"). In the event of a labor dispute or strike the Parties
                agree to provide service to each other at a level equivalent to
                the level they provide themselves.

       26.6     LIMITATION OF LIABILITY

                26.6.1   Each Party shall be liable to the other for direct
                         damages, as described in this section, for any loss,
                         defect or equipment failure resulting from the causing
                         Party's conduct or the conduct of its agents or
                         contractors in performing the obligations contained in
                         this Agreement.

                26.6.2   Except for indemnity obligations, 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 of this Agreement, whether in contract or
                         in tort, shall be limited to the total amount that is
                         or would have been charged to the other Party by such
                         negligent or breaching Party for the service(s) or
                         function(s) not performed or improperly performed.

                26.6.3   Neither Party shall be liable to the other under this
                         Agreement for indirect, incidental, consequential, or
                         special damages, including

                                                                        PAGE 97

<PAGE>

                         (without limitation) damages for lost profits, lost
                         revenues, lost savings suffered by the other Party
                         regardless of the form of action, whether in contract,
                         warranty, strict liability, tort, including (without
                         limitation) negligence of any kind and regardless of
                         whether the Parties know the possibility that such
                         damages could result.

                26.6.4   Nothing contained in this Section shall limit either
                         Party's liability to the other for intentional,
                         malicious misconduct.

                26.6.5   Nothing contained in this Section shall limit either
                         Party's obligations of indemnification as specified in
                         the Indemnity Section of this Agreement.

       26.7     INDEMNITY

                26.7.1   With respect to third party claims, 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.

                26.7.2   The indemnification provided herein shall be
                         conditioned upon:

                         26.7.2.1  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.

                         26.7.2.2  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.

                                                                        PAGE 98

<PAGE>

                         26.7.2.3  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.

       26.8     INTELLECTUAL PROPERTY

                26.8.1   Each Party hereby grants to the other Party the
                         limited, personal and nonexclusive right and license to
                         use its patents, copyrights and trade secrets but only
                         to the extent necessary to implement this Agreement or
                         specifically required by the then applicable federal
                         and state rules and regulations relating to
                         Interconnection and access to telecommunications
                         facilities and 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.

                26.8.2   The rights and licenses above are granted "AS IS" and
                         the other Party's exercise of any such right and
                         license shall be at the sole and exclusive risk of the
                         other Party.  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
                         (hereinafter "claim") 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 of 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.

                26.8.3   As a condition to the access or use of patents,
                         copyrights, trade secrets and other intellectual
                         property (including software) owned or controlled by a
                         third party to the extent necessary to implement this
                         Agreement or specifically required by the then
                         applicable federal and state rules and regulations
                         relating to Interconnection and access to
                         telecommunications facilities and services, the Party
                         providing access may require the other upon written
                         notice, from time to time, to obtain a license or
                         permission for such access or use, make all payments in
                         connection with obtaining such license, and provide
                         evidence of such license.

                26.8.4   Except as expressly provided in this Intellectual
                         Property Section, nothing in this Agreement shall be
                         construed as the grant of a license, either express or
                         implied, with respect to any patent, copyright, logo,
                         trademark, tradename, trade secret or any other
                         intellectual property right now or hereafter owned,
                         controlled or licensable by either Party.  ACI may not
                         use any patent, copyright, logo, trademark, tradename,
                         trade secret or other intellectual

                         property right of USWC or its affiliates without
                         execution of a separate agreement between the Parties.

                26.8.5   ACI shall not, without the express written permission
                         of USWC, state or imply that;  1)  ACI is connected, or
                         in any way affiliated with USWC or its affiliates,  2)
                         ACI is part of a joint business association or any
                         similar arrangement with USWC or its affiliates,  3)
                         USWC and its affiliates are in any way sponsoring,
                         endorsing or certifying ACI and its goods and services,
                         or  4)  with respect to ACI advertising or 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 ACI from truthfully describing
                         the Network Elements it uses to provide service to its
                         end users.

                26.8.6   For purposes of resale only and notwithstanding the
                         above, unless otherwise prohibited by USWC pursuant to
                         an applicable provision herein, ACI may use the phrase
                         "ACI is a reseller of U S WEST Communications services"
                         (the "Authorized Phrase") in ACI's printed materials
                         provided:

                         26.8.6.1  The Authorized Phrase is not used in
                                   connection with any goods or services other
                                   than USWC services resold by ACI.

                         26.8.6.2  ACI's use of the Authorized Phrase does not,
                                   in USWC's sole discretion, cause end users to
                                   believe that ACI is USWC.

                         26.8.6.3  The Authorized Phrase, when displayed,
                                   appears only in text form (ACI may not use
                                   the U S WEST logo) with all letters being the
                                   same font and point size.  The point size of
                                   the Authorized Phrase shall be no greater
                                   than one fourth the point size of the
                                   smallest use of ACI's name and in no event
                                   shall exceed 8 point size.

                         26.8.6.4  ACI shall provide all printed materials to
                                   USWC for its prior written approval.

                         26.8.6.5  If USWC determines that ACI's use of the
                                   Authorized Phrase causes end user confusion,
                                   USWC may in its sole discretion, immediately
                                   terminate ACI's right to use the Authorized
                                   Phrase.

                         26.8.6.6  Upon termination of ACI's right to use the
                                   Authorized Phrase or termination of this
                                   Agreement, all permission or right to use the
                                   Authorized Phrase shall immediately cease to
                                   exist and ACI shall immediately cease any and
                                   all such

                                                                       PAGE 100

<PAGE>

                                   use of the Authorized Phrase.  ACI shall
                                   either promptly return to USWC or destroy all
                                   materials in its possession or control
                                   displaying the Authorized Phrase.

                26.8.7   ACI acknowledges the value of the marks "U S WEST" and
                         "U S WEST Communications" (the "Marks") and the
                         goodwill associated therewith and acknowledges that
                         such goodwill is a property right belonging to U S
                         WEST, Inc. and USWC respectively (the "Owners").  ACI
                         recognizes that nothing contained in this Agreement is
                         intended as an assignment or grant to ACI of any right,
                         title or interest in or to the Marks and that this
                         Agreement does not confer any right or license to grant
                         sublicenses or permission to third parties to use the
                         Marks and is not assignable.  ACI will do nothing
                         inconsistent with the Owner's ownership of the Marks,
                         and all rights, if any, that may be acquired by use of
                         the Marks shall inure to the benefit of the Owners.
                         ACI will not adopt, use (other than as authorized
                         herein), register or seek to register any mark anywhere
                         in the world which is identical or confusingly similar
                         to the Marks or which is so similar thereto as to
                         constitute a deceptive colorable imitation thereof or
                         to suggest or imply some association, sponsorship, or
                         endorsement by the Owners.  The Owners make no
                         warranties regarding ownership of any rights in or the
                         validity of the Marks.

       26.9     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.

       26.10    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.

                                                                       PAGE 101

       26.11    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) CALENDAR 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.

       26.12    DISCLAIMER OF AGENCY

                Except for provisions herein expressly authorizing a Party to
                act for another, nothing in this Agreement shall constitute a
                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.

       26.13    SEVERABILITY

                In accordance with Section 1 of this Agreement, if one or more
                of the provisions contained herein must be modified because of
                changes in Existing Rules or modifications to arbitration
                proceedings, 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.  In
                all other respects, the provisions of this Agreement are not
                severable.

       26.14    NONDISCLOSURE

                26.14.1  All information, including but not limited to
                         specifications, microfilm, photocopies, magnetic disks,
                         magnetic tapes, drawings, sketches, models, samples,
                         tools, technical information, data, employee records,
                         maps, financial reports, and market data, (i) furnished
                         by one Party to the other Party dealing with end user
                         specific, facility specific, or usage specific
                         information, other than end user information
                         communicated for the purpose of publication of
                         directory database inclusion, or (ii) in written,
                         graphic, electromagnetic, or other tangible form and
                         marked at the time of delivery as "Confidential" or
                         "Proprietary", or (iii) communicated and declared to
                         the receiving Party at the time of delivery, or by
                         written notice given to the receiving Party within ten
                         (10) business

                                                                       PAGE 102

                         days after delivery, to be "Confidential" or
                         "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.

               26.14.1.1 "Proprietary Information" also includes
                         information or data that is learned by one
                         Party by virtue of the operating relationship
                         between the Parties including while one Party
                         is on the premises (including leased
                         collocation space) of the other Party.

                26.14.2  Upon request by the disclosing Party, the receiving
                         Party shall return all tangible copies of Proprietary
                         Information, whether written, graphic or otherwise,
                         except that the receiving Party may retain one copy for
                         archival purposes.

                26.14.3  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.
                         Each Party shall use its best efforts to ensure that
                         its retail operations do not have access to, know of,
                         are permitted to obtain, are provided with, obtain
                         disclosure about or otherwise have communicated to it
                         any information defined as Proprietary Information.

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

                         26.14.4.1 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

                                   orders.

                26.14.5  Effective Date Of This Section.  Notwithstanding any
                         other provision of this Agreement, the Proprietary
                         Information provisions of this Agreement shall apply to

                         if furnished before the date of this Agreement.

       26.15    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.

       26.16    DISPUTE RESOLUTION

                If any claim, controversy or dispute between the Parties, their
                agents, employees, officers, directors or affiliated agents
                ("Dispute") cannot be settled through negotiation, it shall be
                resolved by arbitration conducted by a single arbitrator
                engaged in the practice of law, under the then current rules of
                the American Arbitration Association ("AAA").  The Federal
                Arbitration Act, 9 U.S.C. Secs. 1-16, not state law, shall
                govern the arbitrability of all Disputes.  The arbitrator shall
                not have authority to award punitive damages.  All expedited
                procedures prescribed by the AAA rules shall apply.  The
                arbitrator's award shall be final and binding and may be
                entered in any court having jurisdiction thereof.  The
                prevailing Party, as determined by the arbitrator, shall be
                entitled to an award of reasonable attorneys' fees and costs.
                The arbitration shall occur in Denver, Colorado.  Nothing in
                this Section shall be construed to waive or limit either
                Party's right to seek relief from the Commission or the Federal
                Communications Commission as provided by state or federal law.

                                                                       PAGE 104

                this Agreement, may be brought by either Party more than two
                (2) years after the cause of action accrues.

       26.17    CONTROLLING LAW

                the terms of the Act and the laws of the state where service is

                in the event of any ambiguities, no inferences shall be drawn
                against either Party.

       26.19    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

       26.21    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 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
                and performance of all obligations imposed by applicable law in
                connection with its activities, legal status and property, real
                or personal and, (ii) the acts of its own affiliates,
                employees, agents and contractors during the performance of
                that Party's obligations hereunder.

       26.22    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.

       26.23    REFERENCED DOCUMENTS

                All references to Sections or Appendices shall be deemed to be
                references to Sections of, and Appendices to, this Agreement
                unless the context shall otherwise require.  Whenever any
                provision of this Agreement refers to a technical reference,
                technical publication, ACI practice, USWC practice, any
                publication of telecommunications industry administrative or
                technical standards, or any other document specifically

                document that is in effect, and will include the most recent
                version or edition (including any amendments, supplements,

                ACI practice, USWC practice, or publication of industry
                standards.

       26.24    PUBLICITY AND ADVERTISING

                Neither Party shall publish or use any advertising, sales
                promotions or other publicity materials that use the other

                ACI and USWC may mutually agree to amend this Agreement in
                writing.  Since it is possible that amendments to this
                Agreement may be needed to fully satisfy the purposes and
                objectives of this 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.

       26.26    EXECUTED IN COUNTERPARTS

                This Agreement may be executed in any number of counterparts,
                each of which shall be deemed an original; but such
                counterparts shall together constitute one and the same
                instrument.

       26.27    HEADINGS OF NO FORCE OR EFFECT

                The headings of Sections of this Agreement are for convenience
                of reference only, and shall in no way define, modify or

                provisions of this Agreement.

       26.28    CANCELLATION CHARGES

                Except as provided pursuant to a Network Element, Bona Fide
                Request, or as otherwise provided in any applicable Tariff or
                contract referenced herein, no cancellation charges shall
                apply.

       26.29    REGULATORY APPROVAL

                The Parties understand and agree that this Agreement will be
                filed with the Commission and may thereafter be filed with the
                FCC and shall, at all times, be subject to review by the
                Commission or the FCC.  In the event any such review rejects
                any portion of this Agreement, renders it inoperable or creates
                any ambiguity of requirement for further amendment, the Parties
                agree to meet and negotiate in good faith to arrive at a
                mutually acceptable modification.

                                                                       PAGE 107

       26.30    COMPLIANCE

                Each Party shall comply with all applicable federal, state, and
                local laws, rules and regulations applicable to its performance
                under this Agreement.

       26.31    COMPLIANCE WITH THE COMMUNICATIONS LAW ENFORCEMENT ACT OF 1994
                ("CALEA")

                Each Party represents and warrants that any equipment,
                facilities or 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 provided to the
                other Party under this Agreement to ensure that such equipment,
                facilities and services fully comply with CALEA.

       26.32    COOPERATION

                The Parties agree that this Agreement involves the provision of
                USWC services in ways such services were not previously
                available and the introduction of new processes and procedures
                to provide and bill such services.  Accordingly, the Parties
                agree to work jointly and cooperatively in testing and
                implementing processes for pre-ordering, ordering, maintenance,
                provisioning and billing and in reasonably resolving issues
                which result from such implementation on a timely basis.

       26.33    ENTIRE AGREEMENT

                This Agreement constitutes the entire agreement between the
                Parties and supersedes all prior oral or written agreements,
                representations, statements, negotiations, understandings,
                proposals and undertakings with respect to the subject matter
                hereof.

                                                                       PAGE 108

<PAGE>

                          SCHEDULE TO EXHIBIT 10.2

The Registrant has entered into Interconnection Agreements in substantially the
same form as attached hereto for the following states:  Arizona, Colorado,
Minnesota and Oregon.  These agreements are substantially identical in all
material respects except as to the following:

DATE OF AGREEMENT   August 27, 1998

APPENDIX A: 

For Arizona, Colorado, Minnesota and Oregon, respectively, replace Appendix A 
in its entirety as follows:



                                                                   PAGE 111
<PAGE>

FOR ARIZONA: 

Replace Appendix A in its entirety as follows:

                                      APPENDIX A

                                       ARIZONA

These rates reflect the final Arizona Cost Docket Rates Number U-3021-96-448 et
al.  In the event that ACI wishes to order an element described in this
Agreement but not contained in Docket U-3021-96-448, the following will be
applicable.  For Interconnection, Resold Services and Unbundled Network
Elements, ACI and USWC agree to use state-specified permanent rates where
established, or where no state-specified permanent rate exists, the Parties
agree to use the state-specified interim rates where established.  Where no
state-specified permanent or interim rates exist, the Parties agree to use the
ordered and approved AT&T rates as interim rates until such time as the state
Commission issues an order implementing approved permanent or interim rates. 
Where no state-specific or approved AT&T rates exist, USWC TELRIC rates will be
used.  Upon issuance of an order by the state Commission setting state-specified
permanent rates, USWC will move ACI to such approved rates for those states and
true up the amounts charged to that point under state interim rates, AT&T
approved rates or USWC TELRIC rates, from the effective date of the agreement. 
If either state-specified interim or permanent or approved AT&T rates are later
modified upon appeal, on a retroactive basis, a true up will occur.  For
purposes of this Agreement, "Rates" include rate structure.

                                  COLORADO

At the time of signature of this Agreement, all rates shall be in accordance
with current Colorado tariff.

However, for Interconnection, Resold Services and Unbundled Network Elements,
ACI and U S WEST agree to use state-specified permanent rates where established,
or where no state-specified permanent rate exists, the Parties agree to use the
state-specified interim rates where established.  Where no state-specified
permanent or interim rates exist, the Parties agree to use the ordered and
approved AT&T rates as interim rates until such time as the state Commission
issues an order implementing approved permanent or interim rates.  Where no
state-specified or approved AT&T rates exist, U S WEST TELRIC rates will be
used.  Upon issuance of an order by the state Commission setting state-specified
permanent rates, U S WEST will move ACI to such approved rates for those states
and true up the amounts charged to that point under state interim rates, AT&T
approved rates or U S WEST TELRIC rates, from the effective date of the
agreement.  If either state-specified interim or permanent or approved AT&T
rates are later modified on appeal, on a retroactive basis, a true up will
occur.  For purposes of this Agreement, "Rates" include rate structure.

FOR OREGON:

Replace Appendix A in its entirety as follows:

                                 APPENDIX A

                                  OREGON

For Interconnection, Resold Services and Unbundled Network Elements, ACI and 
U S WEST agree to use permanent rates as specified in the current Oregon 
tariff, or where no state-specified permanent rate exists, the Parties agree 
to use the state-specified interim rates where established.  Where no 
state-specified permanent or interim rates exist, the Parties agree to use 
the ordered and approved AT&T rates as interim rates until such time as the 
state Commission issues an order implementing approved permanent or interim 
rates.  Where no state-specified or approved AT&T rates exist, U S WEST 
TELRIC rates will be used.  Upon issuance of an order by the state Commission 
setting state-specified permanent rates, U S WEST will move ACI to such 
approved rates for those states and true up the amounts charged to that point 
under state interim rates, AT&T approved rates or U S WEST TELRIC rates, from 
the effective date of the agreement.  If either state-specified interim or 
permanent or approved AT&T rates are later modified on appeal, on a retroactive
basis, a true up will occur.  For purposes of this Agreement, "Rates" include 
rate structure.


                                                                        PAGE 137
