(4)  KPNQwest Joint Venture

        In April 1999, Qwest and KPN Telecom B. V. ("KPN") completed the
    formation of a joint venture to create a pan-European IP-based fiber optic
    network, linked to Qwest's network in North America, for data, video and
    voice services.

        Qwest and KPN each owns 50 percent of the venture. The venture is
    governed by a six-person supervisory board, to which Qwest and KPN each has
    named three members. KPN contributed two partially completed bi-directional,
    self-healing fiber optic rings (EuroRingsTM 1 and 2) and certain
    communications services contracts. Qwest and KPN have contributed
    transatlantic capacity that connect EuroRingsTM with Qwest's network in
    North America, as well as certain other assets. In April 1999, Qwest
    contributed Xlink Internet Service Gmbh ("Xlink") and the operating
    subsidiaries of EUnet International Limited ("EUnet"). The net book value of
    total assets contributed by Qwest totaled approximately $300.0 million.
    Qwest will deconsolidate EUnet and Xlink, and Qwest's interest in the joint
    venture will be accounted for under the equity method.

</TABLE>

        The Company has entered into various agreements to provide indefeasible
    rights of use of multiple fibers along the network.  Such agreements include
    contracts with three major customers for an aggregate purchase price of
    approximately $1.0 billion.  Construction Services revenue relating to the
    contracts with these major customers was approximately $43.0 million and
    $106.5 million for the three months ended March 31, 1999 and 1998,
    respectively.  Progress billings are made upon customers' acceptance of
    performance milestones.

        Although these construction agreements provide for certain penalties if
    the Company does not complete construction within the time frames specified
    within the agreements, management does not anticipate that the Company will
    incur any substantial penalties under these provisions.

        The current portion of long-term debt and capital lease obligations is
    included in accrued expenses and other in the accompanying condensed
    consolidated balance sheets.

        In March 1999, the Company entered into a $1.0 billion credit agreement
    with a syndicate of banks.  This credit agreement provides for two five-year
    revolving credit facilities for a total of $500.0 million and one 364-day
    revolving credit facility in the amount of $500.0 million.  The credit
    facilities bear interest at either the bank base rate of interest or LIBOR
    plus an applicable margin.


(7)  Income Taxes

        Total income tax expense (benefit) differed from the amounts computed by
    applying the federal statutory income tax rate (35%) to earnings (loss)

(8)  Commitments and Contingencies

    (a) Network Construction Project and Capital Requirements

        In 1996, the Company commenced construction of its network. The Company
    estimates the total cost to construct and activate the network and to
    complete construction of the dark fiber sold to customers will be
    approximately $2.3 billion.  The Company projected its total remaining cost
    as of March 31, 1999 for completing the construction of the network to be
    approximately $0.3 billion.

    (b) DSL Services Commitments

        In January 1999, Qwest made a $15.0 million equity investment in high-
    speed, digital subscriber line ("DSL") local networks through an agreement
    with Covad Communications Group, Inc. ("Covad"), a packet-based Competitive
    Local Exchange Carrier ("CLEC").  The Company has committed to purchase DSL
    services for 

                                       8
<PAGE>
 
QWEST COMMUNICATIONS INTERNATIONAL INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Three Months Ended March 31, 1999 and 1998

    approximately $20.0 million over a five-year term commencing on the date
    that Covad's DSL services are commercially available in all 22 metropolitan
    areas, which is expected to occur by the end of 1999.

        In April 1999, Qwest made an additional equity investment, totaling
    $15.0 million in cash, in DSL local networks through an agreement with
    Rhythms NetConnections Inc. ("Rhythms"), a packet-based CLEC that provides
    high-speed networking solutions for remote access to private networks and
    the Internet. The Company has committed to place a minimum number of orders
    for DSL service over a seven-year term commencing on the date that Rhythms
    is operational in 29 metropolitan areas, which is expected to be in the
    first quarter of 2000. In the event that the Company fails to meet the order
    target, the Company is committed to pay Rhythms for the difference between
    the order target and the number of actual orders placed.

    (c)  Network and Communications Capacity Exchanges

        From time to time, the Company enters into agreements to acquire long-
    term telecommunications capacity rights from unrelated third parties in
    exchange for long-term telecommunications capacity rights along segments of
    the network under construction.  The exchange agreements provide for
    liquidated damages to be levied against the Company in the event the Company
    fails to deliver the telecommunications capacity, in accordance with the
    agreed-upon timetables.

    (d)  Vendor Agreements

        The Company has agreements with certain telecommunications inter-
    exchange carriers and third party vendors that require the Company to
    maintain minimum monthly and/or annual billings based on usage.  The Company
    has historically met all minimum billing requirements and believes the
    minimum usage commitments will continue to be met.

    (e)  Japan-U.S. Cable Consortium Commitment
 
         The Company is participating in a consortium of communications
    companies that is building a submarine cable system connecting the United
    States to Japan. In connection with this transaction, the Company is
    committed to purchase approximately $56.0 million of fiber optic cable and
    other network assets of the 13,125-route-mile, four-fiber pair cable system
    to the Pacific Rim.  The total remaining commitment through January 2001 was
    approximately $49.0 million as of March 31, 1999.

    (f)  Legal Matters

         The Company has been named as a defendant in various litigation
    matters. Management intends to vigorously defend these outstanding claims.
    The Company believes it has adequate accrued loss contingencies and that,
    although the ultimate outcome of these claims cannot be ascertained at this
    time, current pending or threatened litigation matters are not expected to
    have a material adverse impact on the Company's results of operations or
    financial position.


(9) Weighted Average Shares Outstanding

         For the three months ended March 31, 1999, the weighted average number
    of shares used for computing basic earnings per share was 349.1 million, and
    the weighted average number of shares used for computing diluted earnings
    per share was 368.6 million (including 19.5 million incremental common
    shares attributable to dilutive securities related to warrants, options and
    growth shares).  The weighted average number of shares used for computing
    basic and diluted loss per share for the three months ended March 31, 1998
    was 206.7 million.  Because the Company had a net loss in 1998, the effect
    on loss per share of all options and warrants was anti-dilutive.

        The Company's two business segments are Communications Services and
    Construction Services, each having a separate management team and
    infrastructure, offering different products and services, and utilizing
    different marketing strategies to target different types of customers.
    Communications Services provides multimedia communications services to
    retail and wholesale customers.  Construction Services constructs and
    installs fiber optic systems for other communications entities, as well as
    for the Company's own use.

        The Company evaluates the performance of its business segments based on
    their respective earnings (loss) from operations, before interest and other
    (income) expense and income taxes.  The following table presents summarized
    financial information related to the business segments for the three months
    ended March 31, 1999 and 1998 (in millions):

        During the three months ended March 31, 1999, no single customer
    accounted for 10% or more of the Company's total revenue.  During the three
    months ended March 31, 1998, Frontier and GTE accounted for 27% and 27%,
    respectively, of the Company's total revenue and are included in the
    Construction Services segment.


(11)  Subsequent Events

         In May 1999, Qwest's stockholders approved an increase in the number of
     authorized common shares from 600 million to 2 billion.

         In April 1999, BellSouth Corporation (together with its subsidiaries,
     "BellSouth") and Qwest announced a strategic relationship whereby BellSouth
     will invest approximately $3.5 billion for an approximately 10 percent
     equity stake in Qwest.  Qwest will issue approximately 20.35 million shares
     to BellSouth in exchange for approximately $1.9 billion in cash.  Qwest's
     principal stockholder, Anschutz Company, will sell approximately 16.65
     million shares to BellSouth for approximately $1.6 billion.  The investment
     is conditioned on the termination of the Hart-Scott-Rodino Antitrust Act
     waiting period.  At the same time, a BellSouth affiliate and Qwest entered
     into a commercial arrangement for provisioning of a full range of
     integrated digital data, image and voice communications services for
     customers.  These services will include Qwest's portfolio of data
     networking, Internet and voice services and BellSouth's local networking
     services.  Once BellSouth is allowed to enter the long distance market, the
     companies will jointly develop and deliver a comprehensive set of end-to-
     end, high-speed data, image and voice communications services to business
     customers, with an emphasis on broadband and Internet-based data services.

Results of Operations

Information Regarding Forward-Looking Statements

     This report contains or incorporates by reference "forward-looking
statements" as that term is used in federal securities laws about Qwest's
financial condition, results of operations and business. These statements
include, among others:

     .  statements concerning the benefits that Qwest expects will result from
          its business activities and certain transactions Qwest has completed,
          such as increased revenues, decreased expenses and avoided expenses
          and expenditures,

     .  Qwest's plans to complete its communications network, and

     .  other statements of Qwest's expectations, beliefs, future plans and
          strategies, anticipated developments and other matters that are not
          historical facts.

     These statements may be made expressly in this document, or may be
incorporated by reference to other documents Qwest has filed with the Securities
and Exchange Commission ("SEC"). You can find many of these statements by
looking for words such as "believes," "expects," "anticipates," "estimates," or
similar expressions used in this report or incorporated by reference in this

     .  volatility of stock price;

     .  intense competition in the communications services market;

     .  dependence on new product development;

     .  Qwest's ability to achieve year 2000 compliance;

     .  rapid and significant changes in technology and markets;

     .  adverse changes in the regulatory or legislative environment affecting
          Qwest's business; and

     .  failure to maintain necessary rights of way.

     Because the statements are subject to risks and uncertainties, actual
results may differ materially from those expressed or implied by the forward-
looking statements. Qwest cautions you not to place undue reliance on the
statements, which speak only as of the date of this report or, in the case of
documents incorporated by reference, the date of the document.

    The cautionary statements contained or referred to in this section should be
considered in connection with any subsequent written or oral forward-looking
statements that Qwest or persons acting on its behalf may issue. Qwest
undertakes no obligation to review or confirm analysts' expectations or
estimates or to release publicly any revisions to any forward-looking statements
to reflect events or circumstances after the date of this report or to reflect
the occurrence of unanticipated events.

Overview

    Qwest Communications International Inc. ("Qwest" or the "Company") is a
leading Internet communications company engaged in two core businesses:
Communications Services and Construction Services.

    Communications Services includes Internet and Multimedia Services, Business
Services, Consumer Services and Wholesale Services. Internet and Multimedia
Services provides Internet Protocol ("IP") - enabled services such as Internet
access, web hosting, co-location and remote access. Internet and Multimedia
Services are being developed according to market demand in partnership with
leading information technology companies, including the following:

    .  Microsoft Corporation for business applications and service;
    .  Netscape Communications Corporation for one-stop access for an
       array of communications services accessed over the Internet; and
    .  Covad Communications Group, Inc. ("Covad") and Rhythms NetConnections
       Inc. ("Rhythms") for digital subscriber line ("DSL") technology for high-
       speed local network connectivity.

    Business Services and Consumer Services provide a full range of voice, data,
video and related services to business customers, governmental agencies and
consumers. Wholesale Services provides high-volume voice and conventional
private line services to other communications providers, as well as to Internet
service providers ("ISPs"), and other data service companies.

    Construction Services constructs and installs fiber optic systems for other
communications providers, as well as for the Company's own use. The Company
began operations in 1988 constructing fiber optic conduit systems primarily for
major long distance carriers in exchange for cash and capacity rights. The
Company entered into major construction contracts for the sale of dark fiber to
Frontier, MCI WorldCom and GTE whereby the Company has agreed to install and
provide dark fiber to each along portions of the Company's network. In addition
to these contracts, the Company has signed agreements with other communications
providers and government agencies for the sale of dark fiber along the Company's
network. Revenue from Construction Services generally is recognized under the
percentage of completion method as performance milestones relating to the
contract are satisfactorily completed.

    Central to Qwest's strategy is the Qwest Macro Capacity(SM) Fiber Network, a
high-capacity IP-based fiber optic network designed to allow customers to
seamlessly exchange multimedia content -- images, data and voice. The
technologically advanced network will reach approximately 18,800 route miles,
with the initial 18,500-route-mile network scheduled for completion in mid-1999,
and a 300-route-mile segment scheduled for completion by the end of 1999.  The
network employs a self-healing SONET ring architecture. It is equipped with
advanced fiber and state-of-the-art transmission electronics.  Qwest's network
architecture supports IP, Asynchronous Transfer Mode ("ATM") and frame relay
services, as well as circuit switched services.

    In 1998, Qwest became the first network service provider to complete a
transcontinental IP-based fiber optic network when it activated its network from
Los Angeles to San Francisco to New York.   The Company also activated the
nation's first OC-48 native IP network along certain routes of the Company's
network.  Along this OC-48 network, the Company will offer high-speed dedicated
Internet access, web hosting, IP-based virtual private network services and
expanded availability of voice over IP long distance services.  Additionally,
the Company's European joint venture, KPN Qwest, will provide a pan-European IP-
based fiber optic network.  The services offered will allow customers in Europe
to broadcast video, data and voice globally.  (See further discussion of the KPN
joint venture below.)

    The Company is also expanding its network to carry international data and
voice traffic to Mexico, Europe and the Far East. The 1,400-route mile Mexico
network is substantially complete. The network expansion into Europe includes
capacity on undersea submarine systems. The transatlantic capacity includes up
to four STM-1s (the European equivalent to SONET OC-3) from New York City to
London and other European destinations. The Company is also participating in a
consortium of communications companies that is building a submarine cable system
connecting the United States to Japan. Scheduled for completion by the second
quarter of 2000, the 13,125-mile four-fiber pair cable will ultimately be
capable of transmitting information at the rate of 640 gigabits per second.

    Relationship With BellSouth.  In April 1999, BellSouth Corporation (together
with its subsidiaries, "BellSouth") and Qwest announced a strategic relationship
whereby BellSouth will invest approximately $3.5 billion for an approximately 10
percent equity stake in Qwest.  Qwest will issue approximately 20.35 million
shares to BellSouth in exchange for approximately $1.9 billion in cash.  Qwest's
principal stockholder, Anschutz Company, will sell approximately 16.65 million
of existing shares to BellSouth for approximately $1.6 billion. The investment
is conditioned on the termination of the Hart-Scott-Rodino Antitrust Act waiting
period.  At the same time, a BellSouth affiliate and Qwest entered into a

                                       13
<PAGE>
 
commercial arrangement for provisioning of a full range of integrated digital
data, image and voice communications services for customers.  These services
will include Qwest's portfolio of data networking, Internet and voice services
and BellSouth's local networking services.  Once BellSouth is allowed to enter
the long distance market, the companies will jointly develop and deliver a
comprehensive set of end-to-end, high-speed data, image and voice communications
services to business customers, with an emphasis on broadband and Internet-based
data services.

    Investment in Covad.  In January 1999, Qwest made its first equity
investment, totaling $15.0 million in cash, in high-speed, DSL local networks
through an agreement with Covad, a packet-based Competitive Local Exchange
Carrier ("CLEC"). Under this agreement, the Company expects to have access to 22
metropolitan areas by the end of 1999, while enhancing its ability to provide
its customers with high-speed DSL connectivity to its network. The Company has
committed to purchase DSL services for approximately $20.0 million over a five-
year term commencing on the date that Covad's DSL services are commercially
available in all 22 metropolitan areas.

    Investment in Rhythms.  In April 1999, Qwest made an additional equity
investment, totaling $15.0 million in cash, in DSL local networks through an
agreement with Rhythms, a packet-based CLEC that provides high-speed networking
solutions for remote access to private networks and the Internet.  Under this
agreement, the Company expects to have access to 29 metropolitan areas (10 of
which are in addition to the areas covered by the agreement with Covad) by the
first quarter of 2000, while further enhancing its ability to provide its
customers with high-speed DSL connectivity to its network. The Company has
committed to place a minimum number of orders for DSL service over a seven-year
term commencing on the date that Rhythms is operational in 29 metropolitan
areas. In the event that the Company fails to meet the order target, the Company
is committed to pay Rhythms for the difference between the order target and the
number of actual orders placed.

    KPNQwest Joint Venture.  In April 1999, the Company and KPN Telecom B.V.
("KPN") formed a joint venture to create a pan-European IP-based fiber optic
network, linked to the Company's network in North America, for data, video and
voice services.

    The venture initially will offer managed broadband services, IP transit,
Internet connectivity and value-added IP services, including consulting,
hosting, and the broadcasting of live events over the Internet. The venture also
plans to selectively sell dark fiber along its network.  Customers of the
venture will include Internet service and content providers, multinational firms
in Europe and North America, as well as telecommunications carriers, operators
and others who want to purchase wholesale or retail network capacity, fiber or
services.

   Qwest and KPN each own 50 percent of the venture.  The venture is governed by
a six-person supervisory board, to which Qwest and KPN have each named three
members.  KPN contributed two partially completed bi-directional, self-healing
fiber optic rings (EuroRingsTM 1 and 2) and certain communications services
contracts.  Qwest and KPN have contributed transatlantic capacity that connect
EuroRingsTM with Qwest's network in North America, as well as certain other
assets. In April 1999, Qwest contributed Xlink Internet Service Gmbh ("Xlink")
and the operating subsidiaries of EUnet International Limited ("EUnet").  The
net book value of total assets contributed by Qwest totaled approximately $300.0
million.  Qwest will deconsolidate EUnet and Xlink, and Qwest's interest in the
joint venture will be accounted for under the equity method.


Results of Operations

Three Months Ended March 31, 1999 Compared to Three Months Ended March 31, 1998

    The Company reported net earnings of $4.8 million in the first quarter of
1999, compared to a net loss of $(6.6) million in the same quarter of the prior
year.  The Company's results of operations include the acquisitions of the
following:  Phoenix Network, Inc. from March 1998; EUnet International Limited
from April 1998; and LCI International, Inc. from June 1998.  After giving pro
forma effect to these acquisitions and the acquisition of Icon CMT Corp.
("Icon") as if such acquisitions had occurred on January 1, 1998, and excluding
the effects of merger related costs and non-recurring charges, the Company's
reported net loss in the first quarter of 1998 would have been $(20.5) million,
compared to net earnings of $4.8 million in the first quarter of 1999.

</TABLE> 


    During the first quarter of 1999, as compared to the same quarter of the
prior year, Communications Services revenue increased due to the addition of
revenue from the acquisitions discussed above, and due to growth in all aspects
of Communications Services.  Construction Services revenue increased during the
first quarter of 1999, as compared to the same quarter of the prior year,
primarily as a result of additional dark fiber sales to other carriers and the
further completion of construction of the Company's nationwide network.  As the
completion of the Company's network occurs during the remainder of 1999, the
Company expects that revenue from Construction Services will be less significant
to the Company's operations.

    Operating Expenses.  Components of operating expenses for the first quarter
of 1999 and 1998 were as follows (in millions):

</TABLE> 


    Expenses for access and network operations primarily consist of the cost of
operating the Company's network, Local Exchange Carrier ("LEC") access charges
and the cost of leased capacity.  The increase in access and network operations
for the first quarter of 1999 over the same quarter of the prior year was
primarily attributable to growth in revenue from acquisitions, as well as
internally generated growth in Communications Services revenue.  Expressed as a
percentage of communications services revenue, access and network operations
expenses decreased from 72% in the first quarter of 1998  to 59% in the first
quarter of 1999.  As the network is completed and activated, the Company will be
able to serve more customer needs over its own network, thereby reducing such
costs as a percentage of revenue.

    Expenses for Construction Services consist primarily of costs of sale on
network construction contracts, including conduit, fiber, cable, construction
crews and rights of way.  Costs attributable to the construction of the network
for the Company's own use are capitalized.  Expenses for construction services
expressed as a percentage of construction revenue decreased from 72% for the
first quarter of 1998 to 54% for the first quarter of 1999 reflecting the impact
of higher margin network construction contracts.

    Selling, general and administrative ("SG&A") expense includes the cost of
salaries, benefits, occupancy costs, commissions, sales and marketing expenses
and administrative expenses.  The increase in SG&A in the first quarter of 1999
as compared to the same quarter of the prior year, was due primarily to the
following:  additional expenses related to acquired entities; increased sales
and marketing efforts; additional bad debt expense related to the increase in
Communications Services revenues; increased payroll-related costs from the
recruiting and hiring of additional sales and administrative personnel;
increased commissions expense related to the growth in Communications Services
revenue; and additional building rent expense related to increased space
obtained in response to the Company's infrastructure growth.  During the first
quarter of 1999, as compared to the same quarter of the prior year, the number
of employees increased, due to acquisitions and the expansion of the sales and
customer support infrastructure, from approximately 2,000 employees at March 31,
1998 to approximately 9,200 employees at March 31, 1999.  Expressed as a
percentage of total revenue, SG&A decreased from 25% in the first quarter of
1998 to 24% in the first quarter of 1999.  SG&A is expected to increase as the
Company continues to intensify brand advertising, as services are expanded and
as segments of the Company's network become operational.

                                       15

    The Company's depreciation and amortization expense increased due primarily
to activating segments of the Company's network, purchases of assets to
accommodate the Company's growth and depreciation and amortization of assets and
goodwill related to the Company's acquisitions. The Company expects that
depreciation expense will continue to increase in subsequent periods as the
Company continues to activate additional segments of its network.

    Through the use of third-party appraisal consultants, the Company assessed
and allocated values to in-process R&D projects related to the acquisition of
LCI in June 1998.  The values assigned to these assets were determined by
identifying significant research projects for which technological feasibility
had not been established.  These assets consisted of a significant number of R&D
projects grouped into three categories:  (1) network systems automation tools;
(2) advanced data services, including frame relay and Internet Protocol
technologies; and (3) new operational systems and tools.  Taken together, these
projects, if successful, will enable the Company to provide advanced voice and
data services as well as sophisticated network management and administration
functions. The Company believes development efforts through March 31, 1999 have
proceeded according to expectations.

    Remaining R&D efforts for these projects include various phases of
technology design, development and testing. Anticipated completion dates for the
remaining projects in progress will occur in phases through 1999, at which point
the Company expects to begin generating the economic benefits from the
technologies. Costs incurred in connection with these R&D efforts are expensed
as incurred.

    The Company expects to continue its support of these efforts and the Company
believes it has a reasonable chance of successfully completing the R&D programs.
However, risk is associated with the completion of the projects, and the Company
cannot assure that the projects will meet with either technological or
commercial success.

    If none of these projects is successfully developed, the sales and
profitability of the Company may be adversely affected in future periods.  The
failure of any particular individual in-process project would not materially
impact the Company's financial condition or results of operations.  Operating
results are subject to uncertain market events and risks, which are beyond the
Company's control, such as trends in technology, government regulations, market
size and growth, and product introduction or other actions by competitors.

    Other Expense (Income).  Components of other expense (income) for the first
quarter of 1999 and 1998, were as follows (in millions):

</TABLE> 

    The increase in interest expense, net during the first quarter of 1999, as
compared to the same quarter of the prior year, resulted from an increase in
long-term indebtedness, (see "Liquidity and Capital Resources" below), partially
offset by an increase in capitalized interest resulting from construction of the
Company's network.  As the network is completed, interest expense will increase
as the amount of capitalized interest decreases.  Other income, net, decreased
due primarily to decreases in interest income, which resulted from lower average
cash balances.

    Income Taxes.The Company's effective tax rate for the first quarter of 1999
differed from the statutory income tax rate primarily as a result of the non-
deductibility of acquisition-related goodwill and foreign losses.  The effective
tax rate for the first quarter of 1998 differed from the statutory rate
primarily as a result of the non-deductibility of acquisition-related goodwill.


Liquidity and Capital Resources

    During the first quarter of 1999, cash used in operations was $79.6 million;
cash used in investing activities was $315.1 million, including $299.8 million
of capital expenditures; and cash provided by financing activities, consisting
primarily of employee stock transactions, was $50.9 million.

    The Company estimates the total cost to construct and activate its network
and complete construction of dark fiber sold to third parties will be
approximately $2.3 billion, of which the Company had already expended
approximately $2.0 billion as of March 31, 1999.

    The Company is participating in a consortium of communications companies
that is building a submarine cable system connecting the United States to Japan.
In connection with this transaction, the Company is committed to purchase
approximately $56.0 million of fiber optic cable and other network assets of the
13,125-route-mile, four-fiber pair cable system to the Pacific Rim.  The total
remaining commitment through January 2001 was approximately $49.0 million as of
March 31, 1999.

    The Company has obtained the funds available to complete these build-outs
from construction contracts for sales of dark fiber and from various debt and
equity financings.  The Company believes that its available cash and cash
equivalent balances at March 31, 1999, cash flow from operations, cash flow from
the investment by BellSouth and its credit agreement (described below) will
satisfy its currently anticipated cash requirements for at least the next 12
months. The Company anticipates capital expenditures during the remainder of
1999 to support its growth in Communications Services and to complete
construction and activate additional capacity along the Company's network to be
approximately $1.1 billion to $1.2 billion.

    In April 1999, the Company entered into a $1.0 billion credit agreement with
a syndicate of banks.  This credit agreement provides for two five-year
revolving credit facilities for a total of $500.0 million and one 364-day
revolving credit facility in the amount of $500.0 million.  The credit
facilities bear interest at either the bank base rate of interest or LIBOR plus
an applicable margin.


Year 2000

    Many existing computer systems, including hardware and software, use only
the last two digits to identify a year.  Consequently, as the year 2000
approaches, such systems will not recognize the difference in a year that begins
with "20" rather than "19".  As a result of the date change in the year 2000, if
any of the Company's computer systems use only two 

                                       17
<PAGE>
 
digits to define the year, these defective systems may cause disruptions in its
network operations through which the Company provides communications services to
its customers and in its internal operations. Additionally, the Company is
dependent upon outside sources to provide communications services to its
customers and to bill its customers for such services. The greatest risk to the
Company's ability to provide communications services is the failure of third-
party service providers to be year 2000 compliant, especially those third-party
service providers that provide local access and certain of the billing systems
upon which the provision of long distance telecommunications service relies.

    The Company has established a year 2000 compliance group.  The objective of
the year 2000 compliance group is to minimize disruptions as a result of the
date change in the year 2000.  The compliance group has developed a five-step
plan to identify and repair year 2000 affected systems: (i) identify potentially
date-sensitive systems, including third-party products; (ii) assess such systems
for year 2000 compliance; (iii) modify, upgrade or replace non-compliant
systems; (iv) test the corrected systems; and (v) deploy the corrected systems.

    The year 2000 compliance group has focused mainly on the Company's domestic
operations and, to a lesser extent, on its international operations.

    In addition to reviewing its own systems, the year 2000 compliance group is
submitting requests to third-party service providers to obtain information as to
their compliance efforts.

    Inventory, assessment and remediation of mission critical software
applications is substantially complete.  Testing and deployment of corrected
software systems is scheduled for completion by June 30, 1999.

    Inventory and assessment of mission critical hardware systems, including
network computing and network systems engineering, is substantially complete.
Testing and deployment of upgrades necessary to complete remediation of mission
critical systems is expected to be complete by May 31, 1999.  Inventory and
assessment of corporate facilities is scheduled for completion by May 31, 1999,
with necessary upgrades and contingency plans in place by June 30, 1999.

    The Company's overall efforts to integrate the operations of recently
acquired businesses and various other factors, including the compliance efforts
of third parties, over which the Company has no control, may affect these target
dates.

    The Company will develop contingency plans as needed. The contingency plans
are expected to be completed by June 1999 and tested through the third quarter
of 1999.

    During the first quarter of 1999, the Company incurred approximately $3.5
million for year 2000 compliance costs, included in SG&A expense.  The Company
expects to incur approximately $7.0 million to $12.0 million in additional SG&A
expense during the remainder of 1999 to implement its year 2000 plan.  The
Company currently estimates capital expenditures for new systems to replace non-
year 2000 compliant systems will total approximately $20.0 million (having
incurred approximately $4.5 million through March 31, 1999).


Euro Conversion

    On January 1, 1999, 11 of the 15 member countries of the European Union (the
"Participating Countries") established fixed conversion rates between their
existing sovereign currencies and established the euro as their common legal
currency.  Revenues and operating income of the Company's operations in
Participating Countries are less than 5% of the Company's consolidated results.
The Company intends to address operational and information systems issues
related to the euro conversion.  The Company does not expect the euro conversion
to have a material adverse impact on the Company's operations or financial
condition.


Regulatory Matters--Recent Developments

    Access Charge Reform.  Qwest's costs of providing long distance services
could be affected by changes in the "access charges" imposed by local exchange
carriers on long distance carriers to originate and terminate calls over local
networks.  Changes in the interstate access charge structure could also affect
the costs of providing long distance "phone-to-phone" voice services using IP
technology.  Traditionally, providers of long distance voice services over the
Internet and companies that use IP technology to provide long distance services
have been exempt from access charges.

                                       18
<PAGE>
 
    One major local exchange carrier recently demanded, however, that carriers
providing long distance voice services using IP technology must pay access
charges.  In late 1998, US West asked the FCC to consider using its accelerated
complaint procedures to determine whether Qwest's long distance phone-to-phone
voice services using IP technology is subject to the payment of access charges.
Qwest vigorously objected to the FCC's consideration of this issue in an
accelerated fashion.  The FCC subsequently decided not to entertain US West's
complaint using the FCC's accelerated complaint procedures.  US West  was given
the option however, of re-filing its complaint using the FCC's normal complaint
procedures.  In April 1999, US West filed a Petition for Expedited Declaratory
Ruling seeking resolution of whether a long distance carrier is required to pay
access charges when that carrier holds itself out as a provider of voice
telephony; does not require the customer to use customer premises equipment
different from the customer premises equipment necessary to place an ordinary
touch-tone call; allows the customer to call telephone numbers assigned in
accordance with the North American Numbering Plan; and transmits customer
information, without net change in form or content, using a packet switching
protocol solely within the carrier's own network.  As of mid-April 1999, the FCC
has not sought comment on US West's Petition, and has not conclusively
determined whether local exchange carriers may impose access charges on carriers
providing long distance phone-to-phone voice services using IP technology. It is
not clear whether or when a decision will be made.

    In the past, the FCC has suggested that access charges might appropriately
be imposed on long distance phone-to-phone voice services under certain
circumstances.  If the FCC allows local exchange carriers to levy access charges
on carriers providing long distance phone-to-phone voice services using Internet
protocol technology, Qwest's costs to provide such services could increase.

    Supreme Court Decision on FCC Rules Implementing the Telecommunications Act
of 1996.  On January 25, 1999, the U.S. Supreme Court issued a decision that
upheld many of the rules the FCC had created to implement the portions of the
1996 Act that are designed to bring competition to local exchange markets. In
the decision, the Supreme Court upheld the FCC's authority to implement the
Telecommunications Act of 1996 through rules binding on the states.  The Supreme
Court also upheld the FCC's regulations regarding state review of
interconnection agreements, the granting of certain exemptions to rural
incumbent local exchange carriers, and dialing parity.  "Dialing parity" means
that consumers can use non-incumbent carriers by dialing as they normally do,
rather than having to dial extra access codes.  The Supreme Court also upheld
the FCC's rulings:

    .  that competitors need not own facilities in order to purchase network
       elements from incumbent local exchange carriers;

    .  that incumbent local exchange carriers may not separate combinations of
       network elements before providing them to nondominant carriers unless
       requested to do so by a nondominant carrier;

    .  that network elements include the features, functions, and capabilities
       provided by means of network equipment; and

    .  that non-incumbent carriers may adopt particular provisions of another
       carrier's interconnection agreement without adopting the entire
       agreement.

    The Supreme Court sent back to the FCC, however, the issue of what network
elements local exchange carriers must make available to non-incumbent carriers.
In April 1999, the FCC released proposed rules on this subject.  The  FCC is
expected to complete this proceeding later in 1999.  In addition, a federal
court will now need to decide whether the method adopted by the FCC in 1996 for
establishing prices for network elements purchased from the incumbent local
exchange carriers and for interconnection with the incumbent local exchange
carriers' networks is permissible.  Qwest is unable to predict what actions the
FCC or a federal court will take on these and other issues related to the
Supreme Court's decision.

    The Supreme Court's decision is likely to have an impact on other matters as
well, including interconnection agreements between non-incumbent carriers and
incumbent local exchange carriers, the rules the states have adopted concerning
local exchange competition, and the original local exchange carriers'
applications for long distance authority.  Qwest is unable to predict, however,
how the decision will impact those matters or how the decision will affect
competition.

    Truth-in-billing.  In April 1999, the FCC adopted guidelines governing the
format and content of telephone bills.  These guidelines, which are intended to
become effective in the spring of 1999, will require carriers to (1) clearly
identify the service provider responsible for each charge on the bill; (2)
clarify when customers may withhold payment to dispute a charge without risking
the loss of their basic local service; (3) identify on the bill the carrier to
whom a customer should 

                                       19
<PAGE>
 
direct his or her complaint about a particular charge; and (4) adopt uniform
descriptions for line item charges related to federal regulatory action. The
adoption of these new rules will impact the way Qwest presents its bills to
customers.

    1+ Dialing Parity.  In many states, consumers wishing to use carriers other
than the incumbent local exchange carrier for long distance services within the
incumbent local exchange carrier's area have had to dial special access codes to
do so.  The need to dial extra digits in these states has put Qwest and other
carriers at a competitive disadvantage compared with incumbent local exchange
carriers whose customers can make these calls simply by dialing "1" plus the
desired number.  If a non-incumbent carrier's customer attempts to make one of
these calls by simply dialing "1" plus the desired number, the call will
automatically be routed to the incumbent local exchange carrier in those states
that have not required 1+ dialing parity.  The Supreme Court's January 25, 1999
decision which is discussed above upholds the FCC's rule requiring that
incumbent local exchange carriers make it possible for consumers to make these
long distance calls on a 1+ basis, using Qwest or any other carrier the consumer
desires.  Regulatory commissions in a number of states also have issued
decisions imposing similar requirements.  Dialing parity is scheduled to be
implemented in all states by the late summer of 1999. Qwest expects to benefit
from the implementation of this 1+ calling capability.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk

    The Company has $162.5 million of 10 7/8% Senior Notes, due 2007, $555.9
million of 9.47% Senior Discount Notes, due 2007, $450.5 million of 8.29% Senior
Discount Notes, due 2008, $750.0 million of 7.50% Senior Notes, due 2008, $350.0
million of 7.25% Notes Due 2007 and $300.0 million of 7.25% Senior Notes, due
2008.

    The Company's long-term debt obligations are principally fixed interest rate
and non-trading in nature, and as a result, the Company is less sensitive to
market rate fluctuations.  The Company currently does not use derivative
financial instruments to manage its interest rate risk and has no cash flow
exposure due to general interest rate changes for its fixed interest rate long-
term debt.  The following table provides information about the Company's market
risk exposure associated with changing interest rates on its fixed rate debt and
capital lease and other obligations (dollars in millions):

    Collectively, the fixed rate debt, capital lease and other obligations, with
a carrying value of $2,322.1 million, had an estimated fair value of $2,394.5
million at March 31, 1999, based on current interest rates offered for debt of
similar terms and maturity.

    The Company's European-country operations were not material to the Company's
consolidated financial position as of March 31, 1999, and results of operations
or cash flows for the three months ended March 31, 1999.  In addition, foreign
currency transaction gains and losses were not material to the Company's results
of operations for the three months ended March 31, 1999, and the Company does
not expect to be subject to material foreign currency exchange rate risk from
the effects of exchange rate movements of foreign currencies on the costs or
cash flows the Company would receive from its share of the KPNQwest Joint
Venture.  To date, the Company has not entered into any significant foreign
currency forward exchange contracts or other derivative financial instruments to
hedge the effects of adverse fluctuations in foreign currency exchange rates.

                                    Part II

Item 1.  Legal Proceedings

    On April 3, 1998, in an action captioned Lionel Phillips v. LCI
International Inc. and H.  Brian Thompson, the plaintiffs filed a putative class
action complaint in the United States District Court for the Eastern District of
Virginia against LCI and H. Brian Thompson, the Chairman and Chief Executive
Officer of LCI.  The plaintiffs brought the action purportedly on behalf of
stockholders of LCI who sold LCI Common Stock between February 17, 1998 and
March 9, 1998.  The plaintiffs alleged, among other things, that the defendants
violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder
by making materially false and misleading statements that LCI was not for sale
at a time when negotiations between Qwest and LCI regarding a potential merger
were allegedly ongoing.  The plaintiffs sought, among other things, to have the
Court declare the suit a proper class action and award damages, together with
costs and disbursements.  On June 25, 1998, defendants moved to dismiss the
complaint on the grounds that it failed to state a claim against defendants.  By
Order dated July 20, 1998, the Court granted defendants' motion to dismiss the
complaint but granted the plaintiffs leave to amend the complaint within fifteen
days.  On August 4, 1998, the plaintiffs filed an amended complaint and Qwest
again moved to dismiss the lawsuit.  On September 30, 1998, the Court granted
the defendant's motion to dismiss the complaint.  On October 20, 1998, the
plaintiffs appealed the Court's decision and the appeal is still pending.

    On September 15, 1998, in an action captioned Aaron Parnes v. Scott A.
Baxter, Wayne B. Weisman, Richard M. Brown, Scott Harmolin, Samuel A. Plum, Icon
CMT Corp. and Qwest Communications International Inc., the plaintiff filed a
putative class action complaint in the Court of Chancery of the State of
Delaware in and for New Castle County (the "Court") against Icon, its directors
and Qwest.  In the suit, the plaintiff alleged that consummation of the Icon
merger will subject the Icon stockholders to the control of Mr. Anschutz, who
will continue to be the principal stockholder of Qwest after the consummation of
the merger.  The plaintiff further alleged that the Icon merger constitutes a
change in control of Icon and imposes heightened fiduciary duties on the members
of the Icon board of directors to maximize stockholder value.  The plaintiff
also alleged that the members of the Icon board of directors violated their
fiduciary duties by failing to auction Icon or to undertake an active "market
check" for other potential bidders.  The plaintiff seeks, among other things, to
have the Court declare the suit a proper class action, enjoin the Icon merger
and require the members of the Icon board of directors to auction Icon and/or
conduct a "market check," and to award monetary damages, together with costs and
disbursements.  The defendants consider the action to be without merit and
intend to vigorously defend the action.  The defendants have filed answers
denying the allegations of the complaint.

    Qwest also has been named as a defendant in various other litigation
matters. Management intends to vigorously defend these outstanding claims. Qwest
believes it has adequate accrued loss contingencies and that, although the
ultimate outcome of these claims cannot be ascertained at this time, current
pending or threatened litigation matters are not expected to have a material
adverse impact on Qwest's results of operations or financial position.


Item 2.  Changes in Securities and Use of Proceeds

(d)  Use of Proceeds

         Qwest has used approximately $274.6 million of the $319.5 million net
     proceeds from its initial public offering on Form S-1 as declared effective
     on June 23, 1997 (File No. 333-25391) for construction of its fiber optic
     communications network and to redeem a total of $87.5 million in principal
     amount of its 10 7/8% Notes due 2007.  The remaining net proceeds are
     temporarily invested in certain short-term investment grade securities.

of Advances which are Base Advances.  Each such notice of a Borrowing (a
"Borrowing Notice") shall be by telecopy or telephone, promptly confirmed by

                                     ---------                           

               (i) the date of such proposed Borrowing, which shall be a
     Business Day, and whether such Borrowing will be under the Revolver A Loan,
     the Revolver B Loan, or, prior to the Conversion Date, the Working Line
     Loan;

               (ii) the Type of Advances of which the Borrowing is to be

     the unused portion of the Revolver A Commitment, (II) the Revolver B Loan,

     respectively), and (II) in the case of a Borrowing of LIBOR Advances, be in
     an amount of not less than $5,000,000 or an integral multiple of $1,000,000
     in excess thereof; and

               (iv) if the Borrowing is to be comprised of LIBOR Advances, the
     duration of the initial Interest Period applicable to such Advances.

If the Borrowing Notice fails to specify (a) whether such Borrowing is under the

Borrowing shall be deemed to be made under the Revolver A Loan or (b) the
duration of the initial Interest Period for any Borrowing or Refinancing
Advance, as applicable, comprised of LIBOR Advances, such Interest Period shall
be one month.  Administrative Agent shall promptly notify Lenders of each such
notice.  Each Lender shall, before 1:00 p.m. on the date of each Advance under
the Revolver A Loan, the Revolver B Loan and the Working Line Loan hereunder
(other than a Refinancing Advance), make available to Administrative Agent, at
its office at NationsBank Plaza, 901 Main Street, Dallas, Texas  75202, such
Lender's Applicable Specified Percentage of the aggregate Advances under the
respective Loan requested, to be made on that day in immediately available
funds.

     (b) Swingline Advances.  In the case of Swingline Advances, the Borrower
shall give the Swingline Bank and the Administrative Agent irrevocable
telephonic notice prior to 12:00 noon, Dallas, Texas time, on the date of any
proposed Swingline Advance, provided, however, (i) the Borrower shall deliver
written notice at least once a week confirming the telephonic notices given by
the Borrower with respect to Swingline Advances during the immediately preceding

writing shall not invalidate any 

                                       29

notice so given) of its intention to borrow or reborrow a Swingline Advance.
Such notice of borrowing shall specify (i) the requested funding date, which
shall be a Business Day, (ii) the amount of the proposed Swingline Advance and
(iii) the maturity date of the proposed Swingline Advance, which shall be no
longer than 14 calendar days after the date of the proposed Swingline Advance.

     (c) Availability of Funds.  Unless any applicable condition specified in
Article IV has not been satisfied, Administrative Agent will make the funds
promptly available to the Borrower (other than with respect to a Refinancing
Advance) by either (i) wiring such amounts pursuant to any wiring instructions,
or (ii) depositing such amount in the account of the Borrower at the
Administrative Agent, in each case as specified by the Borrower to the
Administrative Agent in writing.

     (d) Number of Interest Periods and Maximum Borrowings.  After giving effect
to any Borrowing, (i) there shall not be more than seven different Interest

(C) the Working Line Loan shall not exceed the Working Line Commitment and (D)

     (e) Interest Period Limitations.  No Interest Period applicable to any
Advance shall extend beyond the Maturity Date.  Prior to the Conversion Date, no
Interest Period for any Working Line Advance shall extend beyond the Conversion
Date, unless the Borrower has elected to exercise its Conversion Option.

     (f) Reliance by Administrative Agent. Unless a Lender shall have notified
Administrative Agent prior to the date of any Advance that it will not make
available its Applicable Specified Percentage of any Advance, Administrative
Agent may assume that such Lender has made the appropriate amount available in
accordance with Section 2.02(a) hereof, and Administrative Agent may, in
reliance upon such assumption, make available to the Borrower a corresponding
amount. If and to the extent any Lender shall not have made such amount
available to Administrative Agent, such Lender and the Borrower severally agree
to repay to Administrative Agent immediately on demand such corresponding amount
together with interest thereon, from the date such amount is made available to
the Borrower until the date such amount is repaid to Administrative Agent, at
(i) in the case of the Borrower, the Base Rate, and (ii) in the case of such
Lender, the Federal Funds Rate.

     (g) Failure by Lender to Make Advance.  The failure by any Lender to make
available its Applicable Specified Percentage of any Advance hereunder shall not
relieve any other Lender of its obligation, if any, to make available its
Applicable Specified Percentage of any Advance.  In no event, however, shall any
Lender be responsible for the failure of any other Lender to make available any
portion of any Advance.

     (h) Swingline Advances and Facility; Repayment of Swingline Advances with
the Proceeds of Revolver A Advances.  The Swingline Bank shall, not later than
2:00 p.m., Dallas, Texas time, on the date of any Swingline Advance, deliver to

                                       30
<PAGE>
 
with the Administrative Agent's instructions. Prior to 2:30 p.m., Dallas, Texas

made available to the Administrative Agent by the Swingline Bank by (i)

instruction or (ii) in the absence of such instructions, crediting such amounts
to the account of the Borrower maintained with the Administrative Agent.
Forthwith upon demand by the Swingline Bank at any time, including after a
Default or Event of Default, and in any event upon the making of the direction
specified by Section 9.02 hereof to authorize the Administrative Agent to
declare the Obligations due and payable pursuant to the provisions of Section
9.02 hereof, each Lender, notwithstanding (i) the failure of the Borrower at
such time to satisfy each condition specified in Article IV hereof or (ii) any
reduction in the Revolver A Commitment, shall make by 12:00 noon (Dallas, Texas
time) on the first Business Day following receipt by such Lender of notice from
the Swingline Bank, a Revolver A Advance which is a Base Rate Advance in an
amount equal to the product of (i) the Revolver A Specified Percentage of such
Lender times (ii) the aggregate outstanding principal amount of the Swingline
Advances (a "Mandatory Borrowing"). The proceeds of such Revolver A Advances
shall be applied by the Administrative Agent to repay the outstanding Swingline
Advances. Each Lender hereby irrevocably agrees to make a Revolver A Advance
pursuant to each Mandatory Borrowing in the amount and in the manner specified
in the preceding sentence and on the date specified in writing by the Swingline
Bank notwithstanding (i) that the amount of the Mandatory Borrowing may not
comply with any minimum amount for Borrowings otherwise required hereunder, (ii)
whether any conditions specified in Article IV hereof are then satisfied, (iii)
whether a Default or an Event of Default then exists, (iv) the date of such
Mandatory Borrowing and (v) the aggregate amount of the Revolver A Commitment at
such time.

        If any Mandatory Borrowing cannot for any reason be made on the date
otherwise required above (including, without limitation, as a result of the
commencement of a proceeding under the Bankruptcy Code with respect to the
Borrower), each Lender hereby agrees that it shall forthwith purchase (as of the
date on which the Mandatory Borrowing would otherwise have occurred, but
adjusted for any payments received from the Borrower on or after such date and
prior to such purchase) from the Swingline Bank such participations in the
outstanding Swingline Advances as shall be necessary to cause the Lenders to
share in such Swingline Advances ratably based upon its Revolver A Specified
Percentage of the Revolver A Commitment (determined before giving effect to any
termination of the Revolver A Commitment); provided that (i) all interest
                                           --------                      
payable on the Swingline Advance shall be for the account of the Swingline Bank
until the date as of which the respective participation is required to be
purchased and, to the extent attributable to the purchased participation, shall
be payable to the participating Lender from and after such date and (ii) at the
time any purchase of participations pursuant to this sentence is actually made,
the purchasing Lender shall be required to pay the Swingline Bank interest on
the principal amount of the participation purchased for each day from and
including the day upon which the Mandatory Borrowing would otherwise have
occurred to but excluding the date of payment for such participation, at the
overnight Federal Funds Rate for the first five days and at the rate otherwise
applicable to Revolver A Advances hereunder for each day thereafter.

     (i) Indemnification. The Borrower shall indemnify each Lender against any
Consequential Loss incurred by each Lender as a result of (i) any failure to
fulfill, on or before the date specified for an Advance, the conditions to the
Advance set forth herein (including a Refinancing Advance) or (ii) the
Borrower's requesting that an Advance (including a Refinancing Advance) not be
made on the date specified in the Borrowing Notice.

Specified Percentage of the Revolver A Commitment in effect on the Closing Date.

     (b) The Advances made by each Lender under the Revolver B Loan shall be
evidenced by a Revolver B Note in the amount of such Lender's Revolver B

a Swingline Note in the amount of $25,000,000.

     (e) Administrative Agent's and each Lender's records shall be presumptive
evidence as to amounts owed Administrative Agent and such Lender under the Notes
and this Agreement.

     2.04.    Optional Prepayments.

     (a) The Borrower may, upon at least two Business Days prior written notice
to Administrative Agent stating the proposed date and aggregate principal amount
of the prepayment, prepay the outstanding principal amount of any Advances in
whole or in part, together with accrued interest to the date of such prepayment
on the principal amount of LIBOR Advances prepaid without premium or penalty
other than any Consequential Loss; provided, however, that in the case of a
                                   --------  -------                       
prepayment of a Base Advance, the notice of prepayment may be given by telephone
by 12:00 p.m. central standard time on the date of prepayment.  Each partial
prepayment shall, in the case of Base Advances under the Loans, be in an
aggregate principal amount of not less than $100,000 or a larger integral
multiple of $50,000 in excess thereof and, in the case of LIBOR Advances under
the Loans, be in an aggregate principal amount of not less than $500,000 or a
larger integral multiple of $100,000 in excess thereof.  If any notice of
prepayment is given, the principal amount stated therein, together with accrued
interest on the amount of LIBOR Advances prepaid and the amount, if any, due
under Section 2.12 and Section 2.14 hereof, shall be due and payable on the date
specified in such notice unless the Borrower revokes its notice, provided that,
if the Borrower revokes its notice of prepayment prior to such date specified,
the Borrower shall reimburse the Administrative Agent for the account of all
Lenders for all Consequential Losses suffered by each Lender as a result of the
Borrower's failure to prepay.  A certificate of each Lender claiming
compensation under this Section 2.04(a), setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim.

     (b) The application of prepayments made under this Section 2.04 as between
the Swingline Loan, the Revolver A Loan, the Revolver B Loan and the Working
Line Loan shall be determined in accordance with the provisions of Section
2.13(f) hereof.  All prepayments made pursuant to this Section 2.04 (other than
to the Swingline Loan) shall be first applied to Base 

                                       32

Advances then to LIBOR Advances, all without premium or penalty, except the
Borrower must pay together with any such prepayments, any Consequential Losses.

Default both before and after giving effect to any such Disposition,

shall immediately use or cause to be used 100% of the Net Proceeds of any such
transaction received by or allocated to the Borrower or such Restricted
Subsidiary as the case may be, to repay the Obligations under the Loans except
to the extent that such Net Proceeds are ultimately reinvested within a 12 month
period after any such asset Disposition, in assets used in the
Telecommunications Business, including, without limitation, the internet,
internet protocol, web hosting or electronic commerce of the Borrower or any of
the Wholly Owned Restricted Subsidiaries, acquisitions permitted under Section

     (b) Mandatory Prepayments, Generally.  The application of prepayments made
under this Section 2.05 as between the Swingline Loan, the Revolver A Loan, the
Revolver B Loan and the Working Line Loan shall be determined in accordance with
the provisions of Section 2.13(f) hereof. All prepayments made pursuant to this
Section 2.05 (other than to the Swingline Loan) shall be first applied to Base
Advances then to LIBOR Advances, all without premium or penalty, except the
Borrower must pay together with such prepayments, any accrued interest on LIBOR
Advances repaid by such prepayments and any Consequential Losses.  After (i) the
Conversion Date, and (ii) the Option Date (if the Borrower and the SuperMajority

payment may be made by means of a Refinancing Advance in accordance with the
terms of Section 2.09 hereof (and subject to the other provisions of this
Agreement).

(i) Revolver A Advances in excess of the Revolver A Commitment as reduced, (ii)
Revolver B Advances in excess of the Revolver B Commitment as reduced, and (iii)
prior to the Conversion Date, Working Line Advances in excess of the Working
Line Commitment shall in each case be immediately due and payable. Each such
principal repayments may not be made by means of Refinancing Advances.

     (c) Option Date and Extension Final Maturity.  The aggregate outstanding
amount of the Working Line Advances shall be due and payable in full on the
Option Date, provided that, notwithstanding the foregoing, on the Option Date if
the Borrower and the SuperMajority Lenders 

                                       33

Extension Option, the aggregate outstanding amount of the Working Line Advances

the Working Line Loan) and all other Obligations shall be due and payable in
full on the Maturity Date.

between Loans under this Section 2.06 shall be determined in accordance with the
terms of Section 2.13(f).  Except for the Swingline Loan, repayment of Advances
shall be applied to Base Advances first, and then to LIBOR Advances.  After (i)
the Conversion Date, and (ii) the Option Date (if the Borrower and the
SuperMajority Lenders did not agree to an Extension Option), Working Line
Advances prepaid hereunder may not be reborrowed.

     2.07.    Interest.

     (a) Revolver A Advances, Working Line Advances and Revolver B Advances.
Subject to Section 2.08 and Section 11.08 hereof, the Borrower shall pay
interest on the unpaid principal amount of each Advance except Swingline
Advances from the date of such Advance until such principal shall be paid in
full, at either the Base Rate or the LIBOR Rate, as set forth in subsection (i)
or (ii) below, as selected by the Borrower in accordance with Section 2.02
hereof and as follows:

          (i) Base Advances.  Base Advances shall bear interest at a rate per
     annum equal to the Base Rate as in effect from time to time.  If the amount
     of interest payable in respect of any interest computation period is
     reduced to the Highest Lawful Rate and the amount of interest payable in
     respect of any subsequent interest computation period would be less than
     the Maximum Amount, then the amount of interest payable in respect of such
     subsequent interest computation period shall be automatically increased to
     the Maximum Amount; provided that at no time shall the aggregate amount by
                         --------                                              
     which interest paid has been increased pursuant to this sentence exceed the
     aggregate amount by which interest has been reduced pursuant to this
     sentence.

          (ii) LIBOR Advances.  LIBOR Advances shall bear interest at the rate
     per annum equal to the LIBOR Rate applicable to such Advance.

          (iii)  Payment Dates.  Accrued and unpaid interest on Base Advances
     shall be paid quarterly in arrears on each Quarterly Date and on the
     Maturity Date.  Accrued and unpaid interest in respect of each LIBOR
     Advance shall be paid on the last day of the appropriate 

                                       34
<PAGE>
 
     Interest Period, on the Maturity Date and on the date of any prepayment or
     repayment of such Advance; provided, however, that if any Interest Period
                                --------  -------          
     for a LIBOR Advance exceeds three months, interest shall also be paid on
     the date which falls three months after the beginning of such Interest
     Period and each three months thereafter until such Interest Period expires.

     (b) Swingline Advances.  The Borrower shall pay interest on the outstanding
principal amount of such Swingline Advance, from the date such Swingline Advance
is made until it is due (whether at maturity, by reason of acceleration or
otherwise) and repaid, at an interest rate per annum equal to a fixed money
market interest rate (plus the Applicable Margin for LIBOR Advances) quoted by
the Swingline Bank and agreed to by the Borrower for such Swingline Advance, but
in no event higher than the Highest Lawful Rate.   Accrued and unpaid interest
on Swingline Advances shall be paid quarterly in arrears on each Quarterly Date
and on the Maturity Date.

     2.08.    Default Interest.  During the continuation of any Event of
Default, the Borrower shall pay, on demand, interest (after as well as before
judgment to the extent permitted by Law) on the principal amount of all Advances
outstanding and on all other Obligations due and unpaid hereunder at a per annum
rate equal to (a) until, for each LIBOR Advance in existence at such time, the
expiration of the applicable Interest Period relating to such LIBOR Advance, the
lesser of (i) the Highest Lawful Rate and (ii) the applicable LIBOR Rate for
such LIBOR Advance plus 2% and (b) for each Base Advance, the lesser of the (i)
the Highest Lawful Rate and (ii) the Base Rate plus 2%. LIBOR Advances shall not
be available for selection by the Borrower during the continuance of an Event of
Default.
 
     2.09.    Continuation and Conversion Elections.

     (a) The Borrower may upon irrevocable written notice to Administrative
Agent and subject to the terms of this Agreement:

               (i) elect to convert, on any Business Day, all or any portion of
     outstanding Advances which are Base Advances (in an aggregate amount not
     less than $500,000 or an integral multiple of $100,000 in excess thereof)
     into LIBOR Advances; or

               (ii) elect to convert at the end of any Interest Period therefor,
     all or any portion of outstanding Advances which are LIBOR Advances
     comprised in the same Borrowing (in an aggregate amount not less than
     $100,000 or an integral multiple of $50,000 in excess thereof) into Base
     Advances; or

               (iii)  elect to continue, at the end of any Interest Period
     therefor, any Advances which are LIBOR Advances;
 
provided, however, that if the aggregate amount of outstanding LIBOR Advances
- --------  -------                                                            
comprised in the same Borrowing shall have been reduced as a result of any
payment, prepayment or conversion of part thereof to an amount less than
$500,000, the LIBOR Advances comprised in such Borrowing shall automatically
convert into Base Advances at the end of each respective Interest Period.

     (b) The Borrower shall deliver a notice of conversion or continuation (a
"Conversion or Continuation Notice"), in substantially the form of Exhibit G
                                                                   ---------
hereto, to Administrative Agent not 

                                       35
<PAGE>
 
later than (i) 12:00 p.m. central standard time three Business Days prior to the
proposed date of conversion or continuation, if the Advances (or any portion of
either thereof) are to be converted into or continued as LIBOR Advances; and
(ii) 12:00 p.m. central standard time on the Business Day of the proposed
conversion, if the Advances (or any portion thereof) are to be converted into
Base Advances.

     Each such Conversion or Continuation Notice shall be by telecopy or
telephone, promptly confirmed by letter, specifying therein:

               (i) the proposed date of conversion or continuation;

               (ii) the aggregate amount of Advances to be converted or
     continued, and whether the Advances are Revolver A Advances, Revolver B
     Advances or Working Line Advances;

               (iii)  the nature of the proposed conversion or continuation; and

               (iv) the duration of the applicable Interest Period.

     (c) If, upon the expiration of any Interest Period applicable to LIBOR
Advances, the Borrower shall have failed to select a new Interest Period to be
applicable to such LIBOR Advances or if an Event of Default shall then have
occurred and be continuing, the Borrower shall be deemed to have elected to
convert such LIBOR Advances into Base Advances effective as of the expiration
date of such current Interest Period.

     (d) Notwithstanding any other provision contained in this Agreement, after
giving effect to any conversion or continuation of any Advances, there shall not
be outstanding Advances with more than seven different Interest Periods.

     2.10.    Fees.

     (a)  Commitment Fees.

          (i) Revolver A Commitment Fee.  Subject to Section 11.08 hereof, the
     Borrower shall pay to Administrative Agent for the account of Lenders pro
     rata in accordance with each Lender's Revolver A Specified Percentage, a
     commitment fee equal to the sum of the Applicable Commitment Fee Percentage
     per annum on the average daily amount of the difference between the
     Revolver A Commitment and the sum of (A) all outstanding Revolver A
     Advances and all outstanding Swingline Advances and (B) the face amount of
     all outstanding Letters of Credit (the "Revolver A Commitment Fee").

          (ii) Working Line Commitment Fee.  Subject to Section 11.08 hereof,
     the Borrower shall pay to Administrative Agent for the account of Lenders
     pro rata in accordance with each Lender's Working Line Specified
     Percentage, a commitment fee equal to the sum of the Applicable Commitment
     Fee Percentage per annum on the average daily amount of the difference
     between the Working Line Commitment and the sum of all outstanding Working
     Line Advances (the "Working Line Commitment Fee").

                                       36
<PAGE>
 
          (iii)  Revolver B Commitment Fee.  Subject to Section 11.08 hereof,
     the Borrower shall pay to Administrative Agent for the account of Lenders
     pro rata in accordance with each Lender's Revolver B Specified Percentage,
     a commitment fee equal to the sum of the Applicable Commitment Fee
     Percentage per annum on the average daily amount of the difference between
     the Revolver B Commitment and the sum of all outstanding Revolver B
     Advances (the "Revolver B Commitment Fee").
          (iv) Commitment Fees, Generally.  Each Commitment Fee set forth in
     subsections (i) through (iii) above shall be payable in arrears on each
     Quarterly Date commencing with the first Quarterly Date after the Closing
     Date, and continuing until the Maturity Date.

     (b) Other Fees.  Borrower shall pay to Administrative Agent and the Lenders
such other fees as set forth in any Fee Letter addressed to the Administrative
Agent or any Lender.

     2.11.    Reduction of Commitments.

     (a) Mandatory Termination of the Revolver A Commitment and the Revolver B
Commitment.  The Revolver A Commitment and the Revolver B Commitment shall both
automatically be reduced to zero and terminate on the Maturity Date.

     (b) Mandatory Reduction of Commitment Due to Asset Sales.  The Commitment
shall be reduced immediately and automatically in an amount equal to any amount
that would be required by Section 2.05(a) hereof to prepay the Loans (regardless
of whether there are any outstanding Obligations under the Loans)  as a result
of any Dispositions of assets and Properties of the Borrower or any of the
Restricted Subsidiaries (this provision in and of itself not constituting
permission to effectuate any asset Dispositions), provided that (i) so long as
there exists no Event of Default both immediately before and after giving effect
to such asset Dispositions and both immediately before and after any permitted
reinvestment and (ii) if a Default exists after giving effect to any such
Disposition, so long as such Default does not ultimately become an Event of
Default, the Commitment shall not be automatically and immediately reduced if
the Borrower in good faith intends to reinvest, and such proceeds are ultimately
reinvested within a 12 month period after any such asset Disposition, in assets
used in the Telecommunications Business, including, without limitation, the
internet, internet protocol, web hosting or electronic commerce of the Borrower
or any of the Wholly Owned Restricted Subsidiaries, acquisitions permitted under
Section 8.18 hereof or Investments permitted under Section 8.04 hereof.

     (c) Option Date or Extension Final Maturity.  (i)  If the Borrower and the
SuperMajority Lenders have not agreed to extend the Working Line Loan final
maturity in accordance with the Extension Option and the Borrower has not
exercised the Conversion Option in accordance with the terms of Section 2.16,
then the Working Line Commitment shall automatically be reduced to zero on the
Option Date.  (ii)   If the Borrower and the SuperMajority Lenders exercised the
Extension Option, then the Working Line Commitment shall automatically be
reduced to zero on the Extension Final Maturity.

     (d) Specified Change of Control.  If any Specified Change of Control shall
have occurred and such Specified Change of Control has caused a Repayment Event
with respect to any of the Existing Financing or any Debt for Borrowed Money in
excess of $25,000,000, each of the Revolver A Commitment, the Revolver B
Commitment, the Swingline Commitment and the Working Line Commitment shall
immediately and automatically be reduced to zero.

                                       37
<PAGE>
 
     (e) Voluntary Commitment Reductions.  The Borrower may from time to time,
upon notice to Administrative Agent not later than 1:00 p.m., three Business
Days in advance, terminate in whole or reduce in part the Commitment, as
designated by the Borrower; provided, however, that the Borrower shall pay the
                            --------  -------                                 
accrued interest and the applicable accrued Commitment Fee on the amount of such
reduction and all amounts due, and any partial reduction shall be in an
aggregate amount which is an integral multiple of $5,000,000.

     (f) Commitment Reduction and Repayments, Generally.  Application of both
voluntary and mandatory reductions of the Commitments as between the Revolver A
Commitment, the Working Line Commitment and the Revolver B Commitment shall be
determined in accordance with the terms of Section 2.13(f) hereof. To the extent
outstanding Revolver A Advances exceed the Revolver A Commitment after any
reduction thereof, the Borrower shall repay, on the date of such reduction, any
such excess amount and all accrued interest thereon, the applicable Revolver A
Commitment Fee on the amount of such reduction and all amounts due.  To the
extent outstanding Revolver B Advances exceed the Revolver B Commitment after
any reduction thereof, the Borrower shall repay, on the date of such reduction,
any such excess amount and all accrued interest thereon, the applicable Revolver
B Commitment Fee on the amount of such reduction and all amounts due. Prior to
the Conversion Date, to the extent outstanding Working Line Advances exceed the
Working Line Commitment after any reduction thereof, the Borrower shall repay,
on the date of such reduction, any such excess amount and all accrued interest
thereon, the applicable Working Line Commitment Fee on the amount of such
reduction and all amounts due.  Once reduced or terminated, none of the Revolver
A Commitment, the Working Line Commitment or the Revolver B Commitment may be
increased or reinstated.  No reduction of the Commitment, either voluntary or
mandatory shall relieve or alter the mandatory reduction and termination of the
Revolver A Commitment, the Working Line Commitment and the Revolver B Commitment
pursuant to this Section 2.11.

      2.12.    Funding Losses.  The Borrower may prepay the outstanding
principal balance of any Advance, in full at any time or in part from time to
time in accordance with the terms of Section 2.04 hereof, provided, that as a
                                                          --------           
condition precedent to the Borrower's right to make, and any Lender's obligation
to accept, any such prepayment, each such prepayment shall be in the amount of
100% of the principal amount to be prepaid, plus, with respect to LIBOR
Advances, accrued unpaid interest thereon to the date of prepayment, plus any
other sums which have become due to Administrative Agent and Lenders under the
Loan Papers on or before the prepayment date but have not been paid, plus
(subject to Section 11.08 hereof) any Consequential Loss.

     The Borrower agrees that each Lender is not obligated to actually reinvest
the amount prepaid in any specific obligation as a condition to receiving any
Consequential Loss, or otherwise.

      2.13.    Computations and Manner of Payments.

     (a) The Borrower shall make each payment hereunder and under the other Loan
Papers not later than 1:00 p.m. on the day when due in same day funds (by wire
transfer or otherwise) to Administrative Agent, for the account of Lenders
unless otherwise specifically provided herein, at Administrative Agent's office
at NationsBank Plaza, 901 Main Street, Dallas, Texas  75202, referencing Qwest
Communications International Inc.  No later than the end of each day when each

                                       38
<PAGE>
 
payment hereunder is made, the Borrower shall notify Loan Operations at (214)
508-9192 or such other Person as Administrative Agent may from time to time
specify.

     (b) Unless Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due hereunder that the
Borrower will not make payment in full, Administrative Agent may assume that
such payment is so made on such date and may, in reliance upon such assumption,
make distributions to Lenders.  If and to the extent the Borrower shall not have
made such payment in full, each Lender shall repay to Administrative Agent
forthwith on demand the applicable amount distributed, together with interest
thereon at the Federal Funds Rate, from the date of distribution until the date
of repayment.  The Borrower hereby authorizes each Lender, if and to the extent
payment is not made when due hereunder, to charge the amount so due against any
account of the Borrower with such Lender.

     (c) Subject to Section 11.08 hereof, interest on LIBOR Advances under the
Loan Papers shall be calculated on the basis of actual days elapsed but computed
as if each year consisted of 360 days.  Subject to Section 11.08 hereof,
interest on Base Advances, the Commitment Fee and other amounts due under the
Loan Papers shall be calculated on the basis of actual days elapsed but computed
as if each year consisted of 365 or 366 days, as applicable.  Such computations
shall be made including the first day but excluding the last day occurring in
the period for which such interest, payment or Commitment Fee is payable.  Each
determination by Administrative Agent or a Lender of an interest rate, fee or
commission hereunder shall be presumptive evidence of the validity of such
claim.  All payments under the Loan Papers shall be made in United States
dollars, and without setoff, counterclaim, or other defense.

     (d) Whenever any payment to be made hereunder or under any other Loan
Papers shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day, and such extension of
time shall be included in the computation of interest or fees, if applicable;
                                                                             
provided, however, if such extension would cause payment of interest on or
- --------  -------                                                         
principal of LIBOR Advances to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (e) Reference to any particular index or reference rate for determining any
applicable interest rate under this Agreement is for purposes of calculating the
interest due and is not intended as and shall not be construed as requiring any
Lender to actually obtain funds for any Advance at any particular index or
reference rate.

     (f) Notwithstanding anything to the contrary herein or in any Loan Paper,
to the extent the Borrower makes any voluntary prepayment, or voluntary
reduction of the Commitment under Section 2.04 or 2.11 hereof, or any mandatory
prepayment, or mandatory reduction of the Commitment under Section 2.05 or 2.11
hereof, then such reduction of Commitment or such prepayment shall be applied as
follows:

          (i) So Long as there Exists No Payment Default or Event of Default.

               (A) Repayments and Prepayments.  So long as there exists no
     Default under Section 9.01(a) hereof or any Event of Default, all voluntary
     and mandatory repayments and prepayments shall be applied as directed by
     the Borrower, and in the absence of direction by the Borrower, shall be
     deemed to repay and prepay (1) the 

                                       39
<PAGE>
 
             Swingline Advances until all the outstandings under the Swingline
             Loan have been paid in full, (2) the Revolver B Advances until all
             the outstandings under the Revolver B Loan have been repaid in
             full, then (3) (only if the date such payment is received is prior
             to the Conversion Date), the Working Line Loan until all the
             outstandings under the Working Line Loan have been repaid in full,
             then (4) the Revolver A Loan until all the outstandings under the
             Revolver A Loan have been repaid in full, then (5) (only is the
             date such payment is received is after the Conversion Date), the
             Working Line Loan, until all outstandings under the Working Line
             loan have been repaid in full, and then (6) all remaining
             outstanding and unpaid Obligations; and

                  (B) Commitment Reductions. So long as there exists no Default
             under Section 9.01(a) hereof or any Event of Default, all voluntary
             and mandatory Commitment reductions shall be applied as directed by
             the Borrower, and in the absence of direction by the Borrower,
             shall be deemed to reduce, respectively, (1) the Revolver B
             Commitment until the Revolver B Commitment has been reduced to
             zero, then (2) if prior to the Conversion Date, the Working Line
             Commitment until the Working Line Commitment has been reduced to
             zero, then (3) the Revolver A Commitment until the Revolver A
             Commitment has been reduced to zero.

             (ii) During the Existence of a Payment Default or Event of Default.

                  (A) Repayments and Prepayments. So long as there exists a
             Default under Section 9.01(a) hereof or any Event of Default, all
             mandatory and voluntary prepayments shall be applied to first to
             Advances outstanding under the Swingline Loan, and secondly to the
             Revolver B Loan, the Revolver A Loan and the Working Line Loan, pro
             rata, until the Advances outstanding under each of the Revolver B
             Loan, the Revolver A Loan and the Working Line Loan have been
             repaid in full, and then to all remaining outstanding Obligations.

                  (B) Commitment Reductions. So long as there exists a Default
             under Section 9.01(a) hereof or any Event of Default, all mandatory
             and voluntary Commitment reductions shall be applied to the
             Revolver A Commitment, the Revolver B Commitment and, if prior to
             the Conversion Date to the Working Line Commitment, pro rata.

     (g)     At all times prior to the Lenders making a Revolver A Advance
pursuant to Section 2.02(h) hereof, the Administrative Agent shall distribute
all payments in respect of the Swingline Advances to the Swingline Bank. At such
time, if any, that the Lenders make a Revolver A Advance pursuant to Section
2.02(h) hereof, the Administrative Agent shall distribute all payments in
respect of the Swingline Advances to the Lenders in accordance with the
respective Revolver A Specified Percentages.

      2.14.  Yield Protection; Changed Circumstances.
 
     (a)     If any Lender determines that either (i) the adoption of any
Applicable Law, rule, regulation or guideline regarding capital adequacy and
applicable to commercial banks or financial institutions generally or any change
therein, or any change, after the date hereof, in the interpretation

                                       40
<PAGE>
 
or administration thereof by any Tribunal, central bank or comparable agency
charged with the interpretation or administration thereof, or (ii) compliance by
any Lender (or Lending Office of any Lender) with any request or directive
applicable to commercial banks or financial institutions generally regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency has the effect of reducing the rate of return
on such Lender's capital as a consequence of its obligations hereunder to a
level below that which such Lender could have achieved but for such adoption,
change or compliance (taking into consideration such Lender's policies with
respect to capital adequacy) by an amount reasonably deemed by such Lender to be
material, then from time to time, within fifteen days after demand by such
Lender, the Borrower shall pay to such Lender such additional amount or amounts
as will adequately compensate such Lender for such reduction. Each Lender will
notify the Borrower of any event occurring after the date of this Agreement
which will entitle such Lender to compensation pursuant to this Section 2.14(a)
as promptly as practicable after such Lender obtains actual knowledge of such
event; provided, no Lender shall be liable for its failure or the failure of any
       --------
other Lender to provide such notification. A certificate of such Lender claiming
compensation under this Section 2.14(a), setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim. If such Lender demands
compensation under this Section 2.14(a), the Borrower may at any time, on at
least five Business Days' prior notice to such Lender (i) repay in full the then
outstanding principal amount of LIBOR Advances, of such Lender, together with
accrued interest thereon, or (ii) convert the LIBOR Advances to Base Advances in
accordance with the provisions of this Agreement; provided, however, that the
                                                  --------  ------- 
Borrower shall be liable for the Consequential Loss arising pursuant to those
actions.

     (b) If, after the date hereof, any Tribunal, central bank or other
comparable authority, at any time imposes, modifies or deems applicable any
reserve (including, without limitation, any imposed by the Board of Governors of
the Federal Reserve System), special deposit or similar requirement against
assets of, deposits with or for the amount of, or credit extended by, any
Lender, or imposes on any Lender any other condition affecting a LIBOR Advance,
the Notes, or its obligation to make a LIBOR Advance, or imposes on any Lender
any other condition affecting a Letter of Credit; and the result of any of the
foregoing is to increase the cost to such Lender of making or maintaining its
Letter of Credit, LIBOR Advances, or to reduce the amount of any sum received or
receivable by such Lender under this Agreement or under the Notes, the Letters
of Credit or reimbursement obligations by an amount deemed by such Lender, to be
material, then, within five days after demand by such Lender, the Borrower shall
          ----                                                                  
pay to such Lender such additional amount or amounts as will compensate such
Lender for such increased cost or reduction.  Each Lender will (i) notify the
Borrower of any event occurring after the date of this Agreement that entitles
such Lender to compensation pursuant to this Section 2.14(b), as promptly as
practicable after such Lender obtains actual knowledge of the event; provided,
                                                                     -------- 
no Lender shall be liable for its failure or the failure of any other Lender to
provide such notification and (ii) use good faith and reasonable efforts to
designate a different Lending Office for LIBOR Advances, of such Lender if the
designation will avoid the need for, or reduce the amount of, the compensation
and will not, in the sole opinion of such Lender, be disadvantageous to such
Lender.  A certificate of such Lender claiming compensation under this Section
2.14(b), setting forth in reasonable detail the computation of the additional
amount or amounts to be paid to it hereunder shall be presumptive evidence of
the validity of such claim.  If such Lender demands compensation under this
Section 2.14(b), the Borrower may at any time, on at least five Business Days'
prior notice to such Lender (i) repay in full the then outstanding principal
amount of LIBOR Advances, of such Lender, together with 

                                       41
<PAGE>
 
accrued interest thereon, or (ii) convert the LIBOR Advances to Base Advances in
accordance with the provisions of this Agreement; provided, however, that the
                                                  --------  ------- 
Borrower shall be liable for the Consequential Loss arising pursuant to those
actions.

     (c) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation or administration of
any Law shall make it unlawful, or any central bank or other Tribunal shall
assert that it is unlawful, for a Lender to perform its obligations hereunder to
issue or maintain Letters of Credit, make LIBOR Advances or to continue to fund
or maintain LIBOR Advances hereunder, then, on notice thereof and demand
therefor by such Lender to the Borrower, (i) each LIBOR Advance will
automatically, upon such demand, convert into a Base Advance, (ii) the
obligation of such Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended until such Lender notifies Administrative Agent and the
Borrower that such Lender has determined that the circumstances causing such
suspension no longer exist, and (iii) the obligation of such Lender to make or
maintain Letters of Credit shall be suspended until such Lender notifies
Administrative Agent and the Borrower that such Lender has determined that the
circumstances causing such suspension no longer exist.

     (d) Upon the occurrence and during the continuance of any Default or Event
of Default, (i) each LIBOR Advance will automatically, on the last day of the
then existing Interest Period therefor, convert into a Base Advance and (ii) the
obligation of each Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended.

     (e) If any Lender notifies Administrative Agent that the LIBOR Rate for any
Interest Period for any LIBOR Advances will not adequately reflect the cost to
such Lender of making, funding or maintaining LIBOR Advances for such Interest
Period, Administrative Agent shall promptly so notify the Borrower, whereupon
(i) each such LIBOR Advance will automatically, on the last day of the then
existing Interest Period therefor, convert into a Base Advance and (ii) the
obligation of such Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended until such Lender notifies Administrative Agent that such
Lender has determined that the circumstances causing such suspension no longer
exist and Administrative Agent notifies the Borrower of such fact.

     (f) Failure on the part of any Lender to demand compensation for any
increased costs, increased capital or reduction in amounts received or
receivable or reduction in return on capital pursuant to this Section 2.14 with
respect to any period shall not constitute a waiver of any Lender's right to
demand compensation with respect to such period or any other period, subject,
however, to the limitations set forth in this Section 2.14.

     (g) The obligations of the Borrower under this Section 2.14 shall survive
any termination of this Agreement, provided that, in no event shall the Borrower
be required to make a payment under this Section 2.14 with respect to any event
of which the Lender making such claim had knowledge more than 12 months prior to
demand for such payment.

     (h) Determinations by Lenders for purposes of this Section 2.14 shall be
presumptively correct.  Any certificate delivered to the Borrower by a Lender
pursuant to this Section 2.14 shall include in reasonable detail the basis for
such Lender's demand for additional compensation and a certification that the
claim for compensation is consistent with such Lender's treatment of similar
customers having similar provisions generally in their agreements with such
Lender.

                                       42
<PAGE>
 
     (i)  Notwithstanding any other provision of this Agreement, no Lender not
organized under the Laws of the United States or any State (or which has a Bank
Affiliate not organized under the Laws of the United States or any State) shall
be entitled to compensation pursuant to this Section 2.14 with respect to any
amount which would otherwise be due under this Section 2.14 but which is the
result of an act of a Tribunal of the country in which such Lender or Bank
Affiliate is organized.

      2.15.  Use of Proceeds.

     (a)  Revolver A Advances and Swingline Advances. The Borrower agrees to use
the proceeds of the Revolver A Loan and the Swingline Facility exclusively to
(i) finance working capital, (ii) refinance certain permitted indebtedness on
the Closing Date, (iii) finance acquisitions permitted under Section 8.18
hereof, (iv) finance Capital Expenditures and (v) for other general corporate
purposes of the Borrower.
 
     (b)  Working Line Advances and Revolver B Advances. The Borrower agrees to
use the proceeds of the Working Line Loan and the Revolver B Loan exclusively
to:

            (i)  Prior to such time as the Senior Unsecured Debt Rating is BBB-
          or Baa3 or better and the Conditional Early Release Unlimited Guaranty
          has been released in accordance with the terms of Section 11.14
          hereof:

               In accordance with certain of the Existing Financing
          Documentation, finance or refinance all or any part of the cost of,
          the construction, installation, acquisition or improvement by the
          Borrower or any Restricted Subsidiary (as defined in the Existing
          Financing Documentation) of the Borrower of any new
          "Telecommunications Assets" (as defined below) constructed, installed,
          acquired or improved after March 31, 1997, provided that (i) the
          proceeds of such debt are expended for such purposes within a 270 day
          period of making such construction, installation, acquisition or
          improvement, and (ii) the amount of such debt does not exceed 100% of
          the cost of the construction, installation, acquisition or improvement
          of the applicable Telecommunications Assets.  For purposes of this
          paragraph, "Telecommunications Assets" means all assets, rights
          (contractual or otherwise) and properties, whether tangible or
          intangible, used or intended for use in connection with the business
          of (A) transmitting or providing services relating to the transmission
          of, voice, data or video through owned or leased transmission
          facilities, (B) constructing, creating, developing or marketing
          communications related network equipment, software and other devices
          for use in a telecommunications business, or (C) evaluating,
          participating or pursuing any other activity or opportunity that is
          primarily related to those identified in (A) or (B) above, provided
          that the determination of what constitutes such businesses shall be
          made in good faith by the Board of Directors.

          (ii)  After the Senior Unsecured Debt Rating is BBB- or Baa3 or better
          and the Conditional Early Release Unlimited Guaranty has been released
          in accordance with the terms of Section 11.14 hereof:

                                       43
<PAGE>
 
               (A)  finance working capital, (B) refinance certain permitted
     indebtedness on the Closing Date, (C) finance acquisitions permitted under
     Section 8.18 hereof, (D) finance Capital Expenditures and (E) for other
     general corporate purposes of the Borrower.

2.16.  Extension Option and Conversion Option Relating to the Working Line 
Loan.

       (a) Extension Option.  On the Option Date, the Borrower, with the
prior written consent of the SuperMajority Lenders and so long as there exists
no Default or Event of Default, may elect to extend the maturity of the Working
Line Loan for an additional 364 day period until the Extension Final Maturity.
Such election must be made no sooner than 60 days prior to the Option Date and
no later than 30 days prior to the Option Date by written notice in accordance
with the terms of Section 11.02 hereof to each Lender of its request to extend
the final maturity of the Working Line Loan. Each Lender shall, no later than 10
Business Days after receipt of such notice, give written notice to the Borrower
and the Administrative Agent of its approval or disapproval of such extension.
Any Lender failing to give such notice shall be deemed to have approved such
extension; but, upon the Option Date, its Working Line Specified Percentage
shall be zero and such Lender shall not be participating in the Working Line
Loan thereafter. Notwithstanding anything herein to the contrary, no Lender
shall be obligated to consent to such extension. If the Borrower fails to
receive the consent of Lenders having Working Line Specified Percentages
totaling 100%, then, if SuperMajority Lenders have consented to such extension
(i) only those consenting Lenders will have Working Line Specified Percentages
in excess of zero, (ii) subject to the terms of Section 2.18 hereof, the Working
Line Commitment shall be reduced by a dollar amount equal to the product of the
non-consenting Lenders' Working Line Specified Percentages times the Working
Line Commitment in effect on the day before the Option Date, (iii) subject to
the terms of Section 2.18 hereof, the Administrative Agent will notify each
Lender of its reallocated Working Line Specified Percentage, the new Working
Line Commitment and the reallocated Total Specified Percentage, (iv) the
Borrower will pay all Consequential Costs incurred as a result of any such
reallocation of Working Line Specified Percentages, (v) subject to the terms of
Section 2.18 hereof, the Borrower shall repay in full all portions of the
Obligations representing such non-consenting Lenders' Working Line Specified
Percentages of all outstanding Working Line Advances to such non-consenting
Lenders, (vi) the Borrower shall execute and deliver new promissory notes to
each extending Lender in the form required by the Administrative Agent and (vii)
subject to satisfaction of each of the foregoing requirements, the Working Line
Loan final maturity shall be automatically extended on the Option Date to the
Extension Final Maturity. If the Borrower receives the consent of Lenders having
Working Line Specified Percentages totaling 100%, then the Working Line Loan
final maturity shall be automatically extended on the Option Date to the
Extension Final Maturity, and each Lender will retain its Working Line Specified
Percentage and the Working Line Commitment shall remain the same.

       (b)  Conversion Option.  On the Option Date, or, if the Borrower and
the Lenders have agreed to extend the Working Line Loan until the Extension
Final Maturity, then the Extension Final Maturity, the Borrower, so long as
there exists no Default or Event of Default on such date of conversion, shall
have the option (which shall not require the consent of any Lender) to convert
the Working Line Loan to a term loan. Such election must be made no sooner than
60 days prior to the Option Date or Extension Final Maturity, as

                                       44
<PAGE>
 
     applicable, and no later than 30 days prior to the Option Date or Extension
     Final Maturity, as applicable, by written notice in accordance with the
     terms of Section 11.02 hereof to each Lender of such conversion. Prior to
     such conversion, the Borrower shall execute and deliver new promissory
     notes to each Lender in the form required by the Administrative Agent. Upon
     such notice and receipt by the Lenders of the new promissory notes, the
     Working Line Loan shall automatically convert to a term loan on the Option
     Date or the Extension Final Maturity, as applicable.

     2.17.  Rights of Borrower in Respect of Consequential Losses.

     (a)    Duty to Mitigate.  If (i) any Lender shall request compensation
under Section 2.14(a) or (b) hereof or (ii) any Lender delivers a notice
described in Section 2.14(c) or (e) hereof then such Lender shall use reasonable
efforts (which shall not require such Lender to suffer any disadvantage or
burden reasonably deemed by it (in good faith) to be significant, including
without limitation, to incur an unreimbursed loss or unreimbursed cost or
expense or otherwise take any action inconsistent with its internal policies or
legal or regulatory restrictions), promptly thereafter, (x) to file any
certificate or document reasonably requested in writing by the Borrower or (y)
to assign its Rights and delegate and transfer its obligations hereunder to
another of its offices, branches or Bank Affiliates, if such filing or
assignment would reduce its claims for compensation under Section 2.14(a) or (b)
hereof or enable it to withdraw its notice pursuant to Section 2.14(c) or (e)
hereof, as the case may be, in the future. The Borrower hereby agrees to pay all
reasonable costs and expenses incurred by any Lender in connection with any such
filing or assignment, delegation and transfer.

     (b) Replacement of a Lender Upon Request for Compensation.  If any Lender
has requested compensation or reimbursement in accordance with the terms of
Section 2.14 hereof and (i) such request is not the result of any uniform
changes in the statutes or regulations for capital adequacy, and (ii) the
Borrower and such Lender are unable to reach a written agreement regarding such
request within 30 days following written notice by such Lender to the Borrower
and the Administrative Agent of such request, then after the expiration of 30
days following the delivery of the notice under Section 2.14 hereof, the
Borrower may replace such Lender in whole with another Lender acceptable to the
Arranging Agents pursuant to an Assignment and Acceptance and in accordance with
Section 11.04 hereof, provided that, such Lender is replaced at par value of all
Obligations owing such Lender plus all accrued interest and fees, provided
further, that Borrower pays the assignment and acceptance fee set forth in
Section 11.04(a) hereof for such replacement. Until such time as any Lender is
replaced by the Borrower, the Borrower shall reimburse or compensate such Lender
in accordance with the terms of Section 2.14 hereof.

      2.18.  Rights of Borrower in Respect of Failure of any Lender to Fund or
Extend the Option Date.  If any Lender shall either (a) breach its agreement to
make any Advance available in accordance with the terms of this Agreement (and
each other Lender shall have made its portion of the Advance available to the
Borrower), or (b) on the Option Date, shall fail to extend the Working Line Loan
for an additional 364 day period in accordance with the terms of Section 2.16(a)
hereof when all such other Lenders have extended, then, in each case, such
Lender shall, promptly upon the written request of the Borrower to such Lender
and the Administrative Agent, assign all of its Rights and duties hereunder and
under the other Loan Papers pursuant to an Assignment and Acceptance in
accordance with the terms of Section 11.04 hereof to another financial
institution or lender designated by the Borrower and acceptable to the Arranging
Agents in accordance with the terms

                                       45
<PAGE>
 
of Section 11.04 hereof, provided that, notwithstanding the foregoing, in no
event shall any Lender be required to take any such action if (a) such Lender is
owed any payments by the Borrower pursuant to this Agreement or the other Loan
Papers, (b) there exists any Default or Event of Default.


                        ARTICLE III.  LETTERS OF CREDIT

     3.01.  Issuance of Letters of Credit.  The Borrower shall give the
Administrative Agent not less than three Business Days prior written notice of a
request for the issuance of a Letter of Credit, and the Administrative Agent
shall promptly notify each Lender of such request.  Upon receipt of the
Borrower's properly completed and duly executed Applications, and subject to the
terms of such Applications and to the terms of this Agreement, including,
without limitation, the satisfaction of the conditions set forth in Section 4.02
hereof, the Administrative Agent agrees to issue Letters of Credit on behalf of
the Borrower in an aggregate face amount not in excess of the Letter of Credit
Commitment.  No Letter of Credit shall have a maturity extending beyond the
earliest of (i) the Maturity Date, or (ii) one year from the date of its
issuance, or (iii) such earlier date as may be required to enable the Borrower
to satisfy its repayment obligations under Section 2.06 hereof. Subject to such
maturity limitations and so long as no Default or Event of Default has occurred
and is continuing or would result from the renewal of a Letter of Credit, the
Letters of Credit may be renewed by the Administrative Agent in its discretion.
The Lenders shall participate ratably in any liability under the Letters of
Credit (including, without limitation, the Existing Letter of Credit)  and in
any unpaid reimbursement obligations of the Borrower with respect to any Letter
of Credit in their Revolver A Specified Percentages.  The amount of the Letters
of Credit issued and outstanding and the unpaid reimbursement obligations of the
Borrower for such Letters of Credit shall reduce the amount of Revolver A
Commitment available, so that at no time shall the sum of (i) all outstanding
Revolver A Advances in the aggregate, plus (ii) all outstanding Swingline
Advances in the aggregate, plus (iii) the aggregate face amount of all
outstanding Letters of Credit, plus (iv) (without duplication) all outstanding
reimbursement obligations related to Letters of Credit, exceed the Revolver A
Commitment, and at no time shall the sum of all Revolver A Advances by any
Lender made plus its ratable share of Swingline Advances and amounts available
to be drawn under the Letters of Credit and the unpaid reimbursement obligations
of the Borrower in respect of such Letters of Credit exceed its Revolver A
Specified Percentage of the Revolver A Commitment.

     3.02.  Letters of Credit Fee.  In consideration for the issuance of each
Letter of Credit, the Borrower shall pay to (a) the Administrative Agent for its
sole account, an application and processing fee in the amount of the higher of
(i) $350.00 and (ii) the product of 1/8th of 1% multiplied by the face amount of
such Letter of Credit on each Letter of Credit, due and payable on the date of
issuance of each Letter of Credit, and (b) the Administrative Agent for the
account of the Administrative Agent and the Lenders in accordance with their
Revolver A Specified Percentages, a per annum fee for each Letter of Credit
equal to the higher of (i) $350.00 and (ii) the product of the Applicable Margin
for a LIBOR Advance in effect on the date of calculation multiplied by the face
amount of each such Letter of Credit.  Each fee for each Letter of Credit under
subsection (b) above shall be due and payable to the Administrative Agent
quarterly as it accrues, on each Quarterly Date during the term of the Letter of
Credit and on the expiration or renewal and/or extension of each such Letter of
Credit, beginning with the first such Quarterly Date after the issuance of each
Letter of Credit and ending on the expiration date of each such Letter of
Credit.

      3.03.  Reimbursement Obligations.

                                       46
<PAGE>
 
     (a)  The Borrower hereby agrees to reimburse Administrative Agent
immediately upon demand by Administrative Agent, and in immediately available
funds, for any payment or disbursement made by Administrative Agent under any
Letter of Credit.  Payment shall be made by the Borrower with interest on the
amount so paid or disbursed by Administrative Agent from and including the date
payment is made under any Letter of Credit to and including the date of payment,
at the lesser of (i) the Highest Lawful Rate, and (ii) the sum of the Base Rate
in effect from time to time plus 2% per annum; provided, however, that if the
                                               --------  -------             
Borrower would be permitted under the terms of Section 2.01, Section 2.02 and
Section 4.02 to borrow Revolver A Advances in amounts at least equal to their
reimbursement obligation for a drawing under any Letter of Credit, a Base
Advance by each Lender, in an amount equal to such Lender's Revolver A Specified
Percentage, shall automatically be deemed made on the date of any such payment
or disbursement made by Administrative Agent in the amount of such obligation
and subject to the terms of this Agreement.

     (b)  The Borrower hereby also agrees to pay to Administrative Agent
immediately upon demand by Administrative Agent and in immediately available
funds, as security for their reimbursement obligations in respect of the Letters
of Credit under Section 3.03(a) hereof and any other amounts payable hereunder
and under the Notes, an amount equal to the aggregate amount available to be
drawn under Letters of Credit then outstanding, irrespective of whether the
Letters of Credit have been drawn upon, upon an Event of Default.  Any such
payments shall be deposited in a separate account designated "Qwest
Communications International Inc. Special Account" or such other designation as
Administrative Agent shall elect.  All such amounts deposited with
Administrative Agent shall be and shall remain funds of the Borrower on deposit
with Administrative Agent and may be invested by Administrative Agent as
Administrative Agent shall determine.  Such amounts may not be used by
Administrative Agent to pay the drawings under the Letters of Credit; however,
such amounts may be used by Administrative Agent as reimbursement for Letter of
Credit drawings which Administrative Agent has paid.  During the existence of an
Event of Default but after the expiration of any Letter of Credit that was not
drawn upon, the Borrower may direct the Administrative Agent to use any cash
collateral for any such expired Letter of Credit, if any, to reduce the amount
of the Obligations.  Any amounts remaining in the Qwest Communications
International Inc. Special Account, after the date of the expiration of all
Letters of Credit and after all Obligations have been paid in full, shall be
repaid to the Borrower promptly after such expiration and such payment in full.

     (c)  The obligations of the Borrower under this Section 3.03 will continue
until all Letters of Credit have expired and all reimbursement obligations with
respect thereto have been paid in full by the Borrower and until all other
Obligations shall have been paid in full.

     (d)  The Borrower shall be obligated to reimburse Administrative Agent upon
demand for all amounts paid under the Letters of Credit as set forth in Section
3.03(a) hereof; provided, however, if the Borrower for any reason fails to
reimburse Administrative Agent in full upon demand, whether by borrowing
Revolver A Advances to pay such reimbursement obligations or otherwise, the
Lenders shall reimburse Administrative Agent in accordance with each Lender's
Revolver A Specified Percentage for amounts due and unpaid from the Borrower as
set forth in Section 3.04 hereof; provided, however, that no such reimbursement
made by the Lenders shall discharge the Borrower's obligations to reimburse
Administrative Agent.

                                       47
<PAGE>
 
     (e)  The Borrower, as to Letters of Credit issued for its account, shall
indemnify and hold harmless the Administrative Agent, the Lead Arranger, each
Lender and their respective affiliates, officers, directors, employees, agents
and advisors (each, an "Indemnified Party") from and against any and all claims,
damages, losses, liabilities and expenses (including, without limitation,
reasonable fees and disbursements of counsel) which may be incurred by or
asserted or awarded against any Indemnified Party, in each case arising out of
or in connection with or by reason of, or in connection with the preparation for
a defense of, any investigation, litigation or proceeding arising out of,
related to or in connection with the Letters of Credit, including without
limitation, any transaction in which any Letter of Credit is being issued and in
connection with actions taken under the Letters of Credit or in connection
therewith, whether or not an Indemnified Party is a party thereto, whether or
not the transactions contemplated herein are consummated, and whether or not
such claim, damage, loss, liability or expense results from the negligence of
such Indemnified Party and except only to the extent such claim, damage, loss,
liability or expense is found in a final, non-appealable judgment by a court of
competent jurisdiction to have resulted from such Indemnified Party's gross
negligence or willful misconduct.  Borrower will not settle or consent to
judgment with respect to any investigation, litigation, or proceeding without
the prior written consent of the Administrative Agent and any affected
Indemnified Party, unless such settlement or consent includes an unconditional
release of each such Indemnified Party or unless each Indemnified Party is
entitled to be indemnified under this Section 3.03(e) (which entitlement the
Borrower will confirm to such Indemnified Party in writing, if requested).  The
Borrower shall periodically, upon request, reimburse each Indemnified Party for
its reasonable legal and other actual expenses (including the cost of any
investigation and preparation) incurred in connection with any indemnified
matter.  The reimbursement, indemnity and contribution obligations under this
Section shall be in addition to any liability which the Borrower may otherwise
have, shall extend upon the same terms and conditions to each Indemnified Party,
and shall be binding upon and inure to the benefit of any successors, assigns,
heirs and personal representatives of the Borrower, the Administrative Agent,
the Lenders and all other Indemnified Party.  This Section shall survive any
termination of this Agreement and repayment of the Obligations.  If the Borrower
for any reason fails to indemnify or pay Administrative Agent or such
Indemnified Party as set forth herein in full, the Lenders shall indemnify and
pay Administrative Agent upon demand, in accordance with each Lender's Revolver
A Specified Percentage, such amounts due and unpaid from the Borrower.  The
provisions of this Section 3.03(e) shall survive the termination of this
Agreement.

     3.04.  Lenders' Obligations.  Each Lender agrees, unconditionally and
irrevocably to reimburse Administrative Agent on demand for such Lender's
Revolver A Specified Percentage of each draw paid by Administrative Agent under
any Letter of Credit that is not reimbursed by the Borrower in accordance with
Section 3.03 hereof.  Each Lender specifically acknowledges that the Existing
Letter of Credit which was issued prior to the Closing Date shall be included in
the definition of Letters of Credit and each Lender shall be obligated to the
Administrative Agent with respect thereto on the identical terms and conditions
it is obligated to the Administrative Agent with respect to all of the other
Letters of Credit, provided that Administrative Agent was not aware of any
payment default or event of default under the Existing Letter of Credit on the
Closing Date.  All amounts payable by any Lender under this subsection shall
include interest thereon at the Federal Funds Rate, from the date of the
applicable draw to the date of reimbursement by such Lender.  No Lender shall be
liable for the performance or nonperformance of the obligations of any other
Lender under this Section.  The obligations of the Lenders under this Section
shall continue after the Maturity Date and shall survive termination of any Loan
Papers.

     3.05.  Administrative Agent's Obligations.

     (a)  Administrative Agent makes no representation or warranty, and assumes
no responsibility with respect to the validity, legality, sufficiency or
enforceability of any Application or any document relative thereto or to the
collectibility thereunder.  Administrative Agent assumes no responsibility for
the financial condition of the Borrower and its Subsidiaries or for the
performance of any obligation of the Borrower.  Administrative Agent may use its
discretion with respect to exercising or refraining from exercising any rights,
or taking or refraining from taking any action which may be vested in it or
which it may be entitled to take or assert with respect to any Letter of Credit
or any Application.

     (b)  Administrative Agent shall be under no liability to any Lender, with
respect to anything the Administrative Agent may do or refrain from doing in the
exercise of its judgment, the sole liability and responsibility of
Administrative Agent (except as otherwise provided in (c) below) being to handle
each Lender's share on as favorable a basis as Administrative Agent handles its
own share and to promptly remit to each Lender its share of any sums received by
Administrative Agent under any Application.  Administrative Agent shall have no
duties or responsibilities except those expressly set forth herein and those
duties and liabilities shall be subject to the limitations and qualifications
set forth herein.

     (c)  Neither Administrative Agent nor any of its directors, officers, or
employees shall be liable for any action taken or omitted (whether or not such
action taken or omitted is expressly set forth herein) under or in connection
herewith or any other instrument or document in connection herewith, except for
gross negligence or willful misconduct, and no Lender waives its right to
institute legal action against Administrative Agent for wrongful payment of any
Letter of Credit due to Administrative Agent's gross negligence or willful
misconduct.  Administrative Agent shall incur no liability to any Lender, the
Borrower or any Affiliate of the Borrower or Lender in acting upon any notice,
document, order, consent, certificate, warrant or other instrument reasonably
believed by Administrative Agent to be genuine or authentic and to be signed by
the proper party.


                       ARTICLE IV.  CONDITIONS PRECEDENT

     4.01.  Conditions Precedent to the Initial Advance and the Issuance of
the Initial Letter of Credit.  The obligation of each Lender to make the initial
Advance under the Loans, or issue the initial Letter of Credit, is subject to
receipt by the Administrative Agent of each of the following, in form and
substance satisfactory to the Administrative Agent, with a copy (except for the
Notes) for each Lender:

     (a)  a loan certificate of the Borrower certifying as to the accuracy of
its representations and warranties in the Loan Papers, certifying that no
Default or Event of Default has occurred under the terms of this Agreement, and
including a certificate of incumbency with respect to each Authorized Officer,
and containing a representation that the following items are attached thereto,
and that each of such items remains unchanged and valid, except as shown on the
attachments: (i) copies of the Articles of Incorporation of the Borrower and
each of the Material Subsidiaries, certified to be true, complete and correct by

contributes to any Plan other than those disclosed to the Administrative Agent
in writing from time to time.  On the Closing Date, each such Plan is in
compliance in all material respects with the applicable provisions of ERISA, the
Code, and any other applicable Federal or state law, rule or regulation.  On
each date after the Closing Date on which this representation is deemed to be
made, each such Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code, and any other applicable Federal or
state law, rule or regulation, except such non-compliance which is not, and

respect to each Plan of the Borrower and each member of its Controlled Group
(other than a Multiemployer Plan), all reports required under ERISA or any other
Applicable Law to be filed with any

                                       55
<PAGE>
 
governmental authority, the failure of which to file would reasonably result in
liability of the Borrower, or any member of its Controlled Group in excess of
$10,000,000, have been duly filed. All such reports are true and correct in all
material respects as of the date given. On the Closing Date, other than as
disclosed to the Administrative Agent in writing, no such Plan of the Borrower,
or any member of its Controlled Group has any accumulated funding deficiency (as
defined in Section 412(a) of the Code) (without regard to any waiver granted
under Section 412 of the Code), nor has any funding waiver from the Internal
Revenue Service been received or requested. On each date after the Closing Date
on which this representation is deemed to be made, no such Plan of the Borrower,

Revenue Service been received or requested which is, or would reasonably be
expected to cause, a Material Adverse Change. None of the Borrower, or any
member of its Controlled Group has failed to make any contribution or pay any
amount due or owing as required by Section 412 of the Code or Section 302 of
ERISA or the terms of any such Plan prior to the due date under Section 412 of
the Code and Section 302 of ERISA in excess of $10,000,000. There has been no
ERISA Event or any event requiring disclosure under Section 4041(c)(3)(C),

Borrower, or any member of its Controlled Group within 60 months prior to the
Closing Date or thereafter, except as disclosed to the Administrative Agent in
writing. The value of the assets of each Plan (other than a Multiemployer Plan)
of the Borrower and each member of its Controlled Group equaled or exceeded the
present value of the benefit liabilities, determined on an on-going Plan basis,
as defined in Title IV of ERISA, of each such Plan as of the most recent
valuation date using Plan actuarial assumptions at such date. There are no
pending or, to the actual knowledge of an Authorized Officer, threatened claims,
lawsuits or actions (other than routine claims for benefits in the ordinary
course) asserted or instituted against (i) the assets of any Plan or trust or
against any fiduciary of a Plan with respect to the operation of such Plan, or
(ii) the assets of any employee welfare benefit plan within the meaning of
Section 3(1) or ERISA, or against any fiduciary thereof with respect to the
operation of any such plan, except any such claims, lawsuits or actions that are
not, and would not reasonably be expected to cause, a Material Adverse Change.
None of the Borrower, or any member of its Controlled Group has engaged in any
non-exempt prohibited transactions, within the meaning of Section 406 of ERISA
or Section 4975 of the Code, in connection with any Plan, except such
transactions which are not, or would not in the aggregate reasonably be expected
to cause, a Material Adverse Change. None of the Borrower or any member of its
Controlled Group has incurred or reasonably expects to incur any liability under
Title IV of ERISA (other than premiums due under Section 4007 of ERISA to the
PBGC) in excess of $10,000,000. None of the Borrower any member of its
Controlled Group, or, to the actual knowledge of any Authorized Officer, any
organization to which the Borrower or any member of its Controlled Group is a
successor or parent corporation within the meaning of ERISA Section 4069(b), has
engaged in a transaction within the meaning of ERISA Section 4069. None of the
Borrower or any member of its Controlled Group maintains or has established any
welfare benefit plan within the meaning of Section 3(1) of ERISA which provides
for continuing benefits or coverage for any participant or any beneficiary of
any participant after such participant's termination of employment except as may
be required by the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended ("COBRA") and the regulations thereunder, and at the expense of the
participant or the beneficiary of the participant, or retiree medical
liabilities, except any such plan that would not reasonably be expected to
result in material liability to the Borrower or any Material Subsidiary. Each of
the Borrower and its Controlled Group which maintains a welfare benefit plan
within the meaning of Section 3(1) of ERISA has complied in all material
respects with any

                                       56
<PAGE>
 
applicable notice and continuation requirements of COBRA and the regulations
thereunder, except where any such noncompliance has not caused, or would not
reasonably be expected to cause, liability to the Borrower or any Material
Subsidiary in excess of $10,000,000.

     (m)  Margin Stock.  The Borrower is not, nor are any of the Restricted
          ------------                                                     
Subsidiaries, engaged principally or as one of its important activities in the
business of extending credit for the purpose of purchasing or carrying any
margin stock within the meaning of Regulations T, U and X of the Board of
Governors of the Federal Reserve System, and no part of the proceeds of the
Advances will be used to purchase or carry any margin stock (as defined by
Regulation U) or to extend credit to others for the purpose of purchasing or
carrying any margin stock.  Not more than 25% of the assets of any of the
Borrower or any of its Subsidiaries are margin stock (as defined by Regulation
U).  None of the Borrower and its Subsidiaries, nor any agent acting on their
behalf, has taken any action which might cause this Agreement or any Loan Papers
to violate any regulation of the Board of Governors of the Federal Reserve

compliance with all of the provisions of their articles of incorporation.  The
Borrower and the Material Subsidiaries are in material compliance with all of
the provisions of their by-laws.  No event has occurred or failed to occur,
which has not been remedied or waived, the occurrence or non-occurrence of which
constitutes, or which with the passage of time or giving of notice or both would
constitute, an Event of Default.

its Subsidiaries, required to register under the provisions of the Investment
Company Act of 1940, as amended (the "ICA").  Neither the entering into or
performance by the Borrower of this Agreement nor the issuance of the Notes, nor
the execution, delivery and performance of the obligations by the Borrower and
its Restricted Subsidiaries under the Loan Papers, violates any provision of the
ICA or requires any consent, approval, or authorization of, or registration
with, the Securities and Exchange Commission or any other governmental or public
body of authority pursuant to any provisions of the ICA.

deemed to be made, no Authorized Officer of the Borrower or any Restricted
Subsidiary has any actual knowledge that any Hazardous Substance has been

the Borrower and the Restricted Subsidiaries are not in material violation of or
subject to any existing, pending or material threatened formal investigation or
formal inquiry by any governmental authority, or subject to any material
remedial obligations under any applicable Environmental Laws. On each date after
the Closing Date on which this representation is deemed to be made, to the
actual knowledge of an Authorized Officer, the Borrower and the Restricted
Subsidiaries are not in violation of or subject to any existing, pending or
threatened formal investigation or inquiry by any governmental authority or to
any remedial obligations under any applicable Environmental Laws which in each
case is, or would reasonably be expected to cause, a Material Adverse Change. To
the actual knowledge of an Authorized Officer, the Borrower and the Restricted
Subsidiaries are not required to obtain any material permits, Licenses or
similar authorizations to construct, occupy, operate or use any buildings,
improvements, fixtures, and equipment forming a part of any real property of the
Borrower or any Restricted Subsidiary by reason of any applicable Environmental
Laws, except those that have been obtained, or which the failure to obtain has
not, and would not reasonably be expected to cause, a Material Adverse Change.
As of the Closing Date, except as set forth in Schedule 5.01(p) hereto, no

Substances or solid wastes have been released on or to the real property of the
Borrower or any of its Restricted Subsidiaries in violation of any applicable
Environmental Law, except such violations which are not, and would not
reasonably be expected to cause, liability to the Borrower and/or the Restricted
Subsidiaries in the aggregate in excess of $10,000,000.  On each date after the
Closing Date on which this representation is deemed to be made, no Authorized
Officer of the Borrower and the Restricted Subsidiaries has actual knowledge
that any Hazardous Substances or solid wastes have been disposed of or otherwise
released on or to the real property of the Borrower or any of the Restricted
Subsidiaries, in violation of the applicable Environmental Laws, except any such
disposal or release which is not, and would not reasonably be expected to cause,
a Material Adverse Change.

     (q)  Subsidiaries.  As of the Closing Date, the Borrower has no
          ------------
Subsidiaries other than those Subsidiaries specifically disclosed in part (a) of
Schedule 5.01(q) hereto and has no equity investments in any other Person other

          -------------                                                
commission will be payable by the Borrower (other than to the Agents and the
Lenders hereunder) with respect to the making of the Commitment or the Advances
hereunder.

     (s)  Intellectual Property.  To the actual knowledge of the Authorized
          ---------------------                                            
Officers as of the Closing Date, the Borrower and its Restricted Subsidiaries
have obtained all licenses of material patents, trademarks, service-marks, trade
names, copyrights, and other rights from third parties that are necessary for
the operation of their business as presently conducted.  On each date afer the
Closing Date on which this representation is deemed to be made, the Borrower and
the Restricted Subsidiaries have obtained all Licenses of patents, trademarks,
service-marks, trade names, copyrights and other similar rights that are
necessary for the operation of their business as presently conducted, except
those, the failure of which to obtain has not caused, and would not reasonably
be expected to cause, a Material Adverse Change.  Nothing has come to the
attention of the Borrower or any of the Restricted Subsidiaries to the effect
that (i) any process, method, part or other material presently contemplated to
be employed by the Borrower or any Material Subsidiary may infringe any patent,
trademark, service-mark, trade name, copyright, or other right owned by any
other Person except to the extent Borrower or any of the Restricted Subsidiaries
has obtained a License therefor,

                                       58
<PAGE>
 
or (ii) there is pending or overtly threatened any claim or Litigation against
or affecting the Borrower or any Material Subsidiary contesting its right to
sell or use any such process, method, part or other material, except in the case
of clause (i) and (ii) above, any such event or circumstance which has not
caused, and would not reasonably be expected to cause, a Material Adverse
Change.

     (t)  Accuracy of Borrower Information.  On the Closing Date, neither this
          --------------------------------                                    
Agreement nor any other document, certificate or statement (in each case, taken
as a whole but excluding the Offering Memorandum) which has been furnished to
any Lender by or on behalf of the Borrower or any of its Subsidiaries in
connection herewith contained any materially untrue statement of a material fact
or omitted to state a material fact necessary in order to make the statement
contained herein and therein not materially misleading at the time it was
furnished in light of the circumstances under which they were made, provided
                                                                    --------
that notwithstanding anything to the contrary in this Agreement or in the Loan
- ----                                                                          
Papers, the Borrower makes no representation, warranty or guaranty as to any
projections furnished to the Lenders except that they were prepared in good
faith by the Borrower on the basis of assumptions which the Borrower believed
were reasonable as of the date of such projections.  On each date after the
Closing Date on which this representation is deemed to be made, the Borrower
represents that none of the regular or periodic reports, or any registration
statement or prospectus filed by the Borrower or any Restricted Subsidiary with
the Securities and Exchange Commission (or any successor agency) contains any
materially untrue statement of a material fact or omits to state a material fact
necessary in order to make the statement contained therein not materially
misleading at the time of such filing in light of the circumstances under which
they were made.  The historical financial statements of the Borrower and
Guarantor contained in the Offering Memorandum present fairly in all material
respects and in accordance with GAAP (subject to year end adjustments and the
absence of footnotes as to the Borrower's unaudited financial statements
contained therein) the financial position of the Borrower and the Guarantor,
respectively, and their respective consolidated Subsidiaries as of the date of
such financial statements.

     (u)  Year 2000 Compliance.  The Borrower has (A) undertaken such review and
          --------------------                                                  
assessment of its business and operations as it deems appropriate with respect
to Year 2000 Compliance, (B) developed an appropriate plan and timeline for
addressing Year 2000 Compliance issues on a timely basis, and (C) to date,
implemented that plan substantially in accordance with that timetable.  The
aggregate costs to and charges by the Borrower related to Year 2000 Compliance
shall not exceed an amount which is, or would reasonably be expected to cause, a
Material Adverse Change.

     (v)  Existing Financing.  The Loans and the Conditional Early Release
          ------------------                                              
Unlimited Guaranty of the Loans and all Obligations are senior to or pari passu
with all Existing Financing. Nothing in this Agreement and the other Loan Papers
violates any provision of the Existing Financing Documentation, and no consent
is required in connection with any of the Existing Financing Documentation in
order to execute, deliver and perform under this Agreement and the other Loan
Papers.  To the actual knowledge of the Authorized Officers, there exists no
"Default" or "Event of Default" as defined in, and under any of the Existing
Financing Documentation, or any other event or circumstance which causes a
Repayment Event with respect to any of the Existing Financing.  All notices
required by any Existing Financing Documentation regarding the execution,
delivery or performance by the Borrower or any Restricted Subsidiary of the Loan
Papers have been given in accordance with the terms of the Existing Financing
Documentation.

     (w)  Fibers and Fiber Capacity. As of the Closing Date, the Borrower and
          -------------------------
its Restricted Subsidiaries own or have the right to use through the Maturity
Date not less than 24 optical fibers on a weighted average route mile basis on
the Backbone (which such fibers are not subject to any transfer, disposition or
IRU Agreement granting an IRU to any Person other than the Borrower or any
Restricted Subsidiary), and such fiber capacity is sufficient, on a weighted
average route mile basis, to meet the business plan of the Borrower.

     (x)  Sinking Funds and Defeasance.  As of the Closing Date, no
          ----------------------------
documentation relating to any Debt for Borrowed Money of the Borrower or any
Restricted Subsidiary has any provision granting any creditor a sinking fund or
a right to require a defeasance of the obligations owing to it.

     5.02.  Survival of Representations and Warranties.  All representations
and warranties made under this Agreement and the other Loan Papers shall be
deemed to be made at and as of the Closing Date and at and as of the date of
each Advance (excluding each Refinancing Advance), and each shall be true and
correct in all material respects when made (except those representations and
warranties that specifically speak as of a particular date).  All such
representations and warranties shall survive, and not be waived by, the
execution hereof by any Lender, any investigation or inquiry by any Lender, or
by the making of any Advance under this Agreement.


                        ARTICLE VI.  GENERAL COVENANTS

     So long as any of the Obligations are outstanding and unpaid or the

hereof); and

     (b)  The Borrower shall, and shall cause each Restricted Subsidiary to,
qualify and remain qualified and authorized to do business in each jurisdiction

such qualification or authorization, except where the failure to do so is not,
and would not reasonably be expected to cause, a Material Adverse Change.

     6.02.  Business; Compliance with Applicable Law.  The Borrower shall,
and shall cause the Restricted Subsidiaries to (a) engage primarily in the
Telecommunications Business, including, without limitation, the internet,
internet protocol, web hosting or electronic commerce, and (b) comply in all
material respects with the requirements of all material Applicable Law.

     6.03.  Maintenance of Properties.  The Borrower shall, and shall cause

<PAGE>
 
order and condition, taken as a whole, and from time to time make or cause to be
made all appropriate repairs, renewals, replacements, additions, betterments and
improvements thereto.

     6.04.  Accounting Methods and Financial Records.  The Borrower shall,
and shall cause each Restricted Subsidiary to, maintain a system of accounting
established and administered in accordance with GAAP and keep adequate records
and books of account in which complete entries will be made and all transactions

     6.05.  Insurance.  The Borrower shall, and shall cause each Restricted
Subsidiary to, maintain insurance from responsible companies in such amounts and
against such risks as shall be customary and usual in the industry for companies

efforts to cause each insurance policy to provide for at least 30 days' prior
notice to the Administrative Agent of any proposed termination or cancellation
of such policy, whether on account of default or otherwise.

     6.06.  Payment of Taxes and Claims.  The Borrower shall, and shall cause
each of its Restricted Subsidiaries to, pay and discharge all federal and other
material Taxes, assessments and governmental charges or levies imposed upon it
or its income or Properties prior to the date on which penalties attach thereto
which are shown on such Person's Tax returns to be due and payable, and all
lawful material claims for labor, materials and supplies which, if unpaid, might
become a Lien upon any of their Properties or assets, except those Taxes,
assessments and charges which are immaterial or contested by the Borrower
diligently in good faith, and for which adequate reserves have been established
in accordance with GAAP.  The Borrower shall, and shall cause each of its
Restricted Subsidiaries to, timely file all information returns required by
federal Tax Authorities, and all material information returns required by state
or local Tax authorities.
 
     6.07.  Visits and Inspections.  The Borrower shall, and shall cause each
Restricted Subsidiary to, promptly, permit representatives of the Administrative
Agent and the Arranging Agents, or any Lender accompanied by the Administrative

Subsidiary during normal business hours (unless there exists an Event of Default
in which case during such hours as is reasonable under the circumstances), (b)
inspect and make extracts from and copies of the Borrower's and each Restricted
Subsidiary's books and records, in each case as reasonable under the
circumstances, (c) discuss with the Borrower's and each Restricted Subsidiary's

respect to which the Borrower shall be obligated to procure such information

                                       61
<PAGE>
 
     6.09.  Indemnity.  The Borrower agrees to indemnify and hold harmless
the Administrative Agent, the Lead Arranger, the Arranging Agents, the Co-
Arrangers, the Co-Syndication Agents, each Lender and their respective
affiliates, officers, directors, employees, agents and advisors (each, an
"Indemnified Party") from and against any and all claims, damages, losses,
liabilities and expenses (including, without limitation, the reasonable fees and
expenses of counsel and the allocated cost of internal counsel) which may be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of, or in connection with the
preparation for a defense of, any investigation, litigation or proceeding
arising out of, related to or in connection with the Loans, including without
limitation, any transaction in which the proceeds of any borrowing are or are to
be applied, whether or not an Indemnified Party is a party thereto, whether or
not the transactions contemplated herein are consummated, and whether or not
such claim, damage, loss, liability or expense results from the negligence of
such Indemnified Party unless and only to the extent that as to any Indemnified
Party, it shall be determined in a final, non-appealable judgment by a court of
competent jurisdiction that such losses, claims, damages, liabilities, or
expenses resulted from such Indemnified Party's gross negligence or willful
misconduct.  Borrower will not settle or consent to judgment with respect to any
investigation, litigation, or proceeding without the prior written consent of
the Administrative Agent and any affected Indemnified Party, unless such
settlement or consent includes an unconditional release of each such Indemnified
Party or unless each Indemnified Party is entitled to be indemnified under this
Section 6.09 (which entitlement the Borrower will confirm to such Indemnified
Party in writing, if requested).  The Borrower shall periodically, upon request,
reimburse each Indemnified Party for its reasonable legal and other actual
expenses (including the costs of any investigation and preparation) incurred in
connection with any indemnified matter.  The Borrower agrees that no Indemnified
Party shall have any liability for any indirect or consequential damages in
connection with its activities related to the Loans.  The reimbursement,
indemnity and contribution obligations under this Section shall be in addition
to any liability which the Borrower may otherwise have, shall extend upon the
same terms and conditions to each Indemnified Party, and shall be binding upon
and inure to the benefit of any successors, assigns, heirs and personal
representatives of the Borrower, the Administrative Agent, the Lenders and all
other Indemnified Party.  This Section shall survive any termination of this
Agreement and repayment of the Obligations.

     6.10.  Environmental Law Compliance.  The use which the Borrower or any
of its Restricted Subsidiaries intends to make of any real Property owned by it
will not result in the disposal or other release of any Hazardous Substance or
solid waste on or to such real Property in violation of any Environmental Law,
except any such violation which is not, and would not reasonably be expected to
cause, a Material Adverse Change.  As used herein, the term "release" as used in
this Section shall have the meanings specified in CERCLA (as defined in the
definition of applicable Environmental Laws), and the terms "solid waste" and
"disposal" shall have the meaning specified in RCRA (as defined in the
definition of applicable Environmental Laws); provided, however, that if CERCLA
or RCRA is amended so as to broaden or narrow the meaning of any term defined
thereby, such broader or narrower meaning shall apply subsequent to the
effective date of such amendment; and provided further, to the extent that any
other law applicable to the Borrower, any of its Restricted Subsidiaries or any
of their properties and assets establishes a meaning for "hazardous substance,"
"release," "solid waste," or "disposal" which is broader than that specified in
either CERCLA or RCRA, such broader meaning shall apply.  The Borrower and each
Restricted Subsidiary agrees to indemnify and hold the Administrative Agent and
each Lender harmless from and against, and to reimburse them with respect to,
any and all claims, damages, losses, liabilities and expenses (including
reasonable attorneys' fees and courts costs) asserted or awarded against or

                                       62
<PAGE>
 
incurred by any of them by reason of or arising out of transactions contemplated
by this Agreement and (a) the failure of the Borrower or any of its Restricted
Subsidiaries to perform any obligation hereunder regarding asbestos or
applicable Environmental Laws, (b) any violation by the Borrower or Restricted
Subsidiary on or before the Release Date of any applicable Environmental Law in
effect on or before the Release Date, and (c) any act, omission, event or
circumstance existing or occurring on or prior to the Release Date, involving
the presence on such real Property or release from such real Property of
Hazardous Substances or solid wastes disposed of or otherwise released on or
prior to the Release Date, resulting from or in connection with the ownership by
the Borrower or any Restricted Subsidiary of the real Property, regardless of
whether the act, omission, event or circumstance constituted a violation of any
applicable Environmental Law at the time of its existence or occurrence, or
whether the act, omission, event or circumstance is caused by or relates to the
negligence of any indemnified Person; provided, that the Borrower shall not be
under any obligation to indemnify the Administrative Agent or any Lender to the
extent that any such liability arises as the result of the gross negligence or
willful misconduct of such Person, as finally judicially determined by a court
of competent jurisdiction.  The provisions of this Section shall survive the
Release Date and shall continue thereafter in full force and effect.

     6.11.  Restricted Subsidiary Designation.  The Borrower agrees that each
Restricted Subsidiary on the Closing Date will remain a Restricted Subsidiary
until the Obligations have been repaid in full and the Commitment has been
terminated, unless any Restricted Subsidiary that is not a Material Subsidiary
has been Disposed of in accordance with the terms of Section 8.05(a)(ii)(A)
hereof.

     6.12.  Year 2000 Compliance.  The Borrower will promptly notify the
Administrative Agent in the event the Borrower discovers or determines that any
computer application (including those of its suppliers and vendors) that is
material to its or any of the Restricted Subsidiaries, business and operations
will not be Year 2000 Compliant on a timely basis, except to the extent that
such failure is not, and would not reasonably be expected to cause, a Material
Adverse Change.

     6.13.  Fiber Capacity.  The Borrower shall, and shall cause its
Restricted Subsidiaries to, at all times maintain ownership of or the right to
use through the Maturity Date (or until all Obligations are paid in full) not
less than 24 optical fibers on a weighted average route mile basis on the
Backbone, which such fibers may not be transferred, disposed of or made subject
to an IRU Agreement granting an IRU to any Person other than the Borrower or any
Restricted Subsidiary if such transfer, disposal or IRU Agreement would result
in the Borrower and its Restricted Subsidiaries owning or having the right to
use less than 24 optical fibers on a weighted average route mile basis on the
Backbone through the Maturity Date (or until all Obligations are paid in full).

     6.14.  UCC Filings.  The Borrower shall, and shall cause its Restricted
Subsidiaries to, agree to file UCC-3 releases for all UCC filings recorded
against the Borrower and its Restricted Subsidiaries, which such UCC filings
evidence Debt that has been repaid in full and extinguished and do not evidence
Permitted Liens.

     6.15.  Sinking Funds and Defeasance.  To the extent that the Borrower
or any Restricted Subsidiary agrees in connection with the incurrence of any
Debt for Borrowed Money to a sinking fund or defeasance, the Borrower shall, and
shall cause each of its Restricted Subsidiaries to, grant to the Administrative
Agent and the Lenders proportionately similar rights to a sinking fund or
defeasance with respect to the Obligations.

year-end audit adjustments and do not have to contain footnotes), the financial

any of the Existing Financing Documentation or (ii) Repayment Event with respect
to any of the Existing Financing or any other Debt for Borrowed Money in excess

     9.02. Remedies upon Default. If an Event of Default described in Section
9.01(f) shall occur, the aggregate unpaid principal balance of and accrued
interest on all Advances and all other Obligations shall, to the extent
permitted by applicable Law, thereupon become due and payable concurrently
therewith, and the Commitment shall be concurrently automatically reduced to
zero and terminated, all without any action by Administrative Agent or any
Lender, and without diligence, presentment, demand, protest, notice of protest
or intent to accelerate, or notice of any other kind, all of which are hereby
expressly waived. Subject to the foregoing sentence, if any Event of Default
shall occur and be continuing, Administrative Agent may at its election, and
shall at the direction of Majority Lenders, do any one or more of the following:
 
     (a) Declare the entire unpaid balance of all Obligations immediately due
and payable, whereupon it shall be due and payable without diligence,
presentment, demand, protest, notice of protest or intent to accelerate, or
notice of any other kind (except notices specifically provided for 

                                       82
<PAGE>
 
under Section 9.01 hereof), all of which are hereby expressly waived (except to
the extent waiver of the foregoing is not permitted by applicable Law);

     (b) Terminate any of the Revolver A Commitment, the Working Line Commitment
or the Revolver B Commitment, or terminate all of the Commitments;

     (c) Reduce any claim of Administrative Agent and Lenders to judgment;

     (d) Demand (and the Borrower shall pay to Administrative Agent) immediately
upon demand and in immediately available funds, the amount equal to the
aggregate amount of the Letters of Credit then outstanding as cash collateral,
irrespective of whether such Letters of Credit have been drawn upon, all as set
forth and in accordance with the terms of provisions of Article III hereof.  The
Administrative Agent shall promptly advise the Borrower of any such declaration
or demand but failure to do so shall not impair the effect of such declaration
or demand; and

     (e) Exercise any Rights afforded under any Loan Papers, by Law, including
but not limited to the UCC, at equity, or otherwise.

      9.03. Cumulative Rights. All Rights available to Administrative Agent and
Lenders under the Loan Papers shall be cumulative of and in addition to all
other Rights granted thereto at Law or in equity, whether or not amounts owing
thereunder shall be due and payable, and whether or not the Administrative Agent
or any Lender shall have instituted any suit for collection or other action in
connection with the Loan Papers.

      9.04. Waivers. The acceptance by Administrative Agent or any Lender at any
time and from time to time of partial payment of any amount owing under any Loan
Papers shall not be deemed to be a waiver of any Default or Event of Default
then existing. No waiver by Administrative Agent or any Lender of any Default or
Event of Default shall be deemed to be a waiver of any Default or Event of
Default other than such Default or Event of Default. No delay or omission by
Administrative Agent or any Lender in exercising any Right under the Loan Papers
shall impair such Right or be construed as a waiver thereof or an acquiescence
therein, nor shall any single or partial exercise of any such Right preclude
other or further exercise thereof, or the exercise of any other Right under the
Loan Papers or otherwise.

      9.05. Performance by Administrative Agent or any Lender.  Should any
covenant of any Obligor or Restricted Subsidiary fail to be performed in
accordance with the terms of the Loan Papers, Administrative Agent may, at its
option, perform or attempt to perform such covenant on behalf of such Obligor or
Restricted Subsidiary.  Notwithstanding the foregoing, it is expressly
understood that the Administrative Agent does not assume, and shall not ever
have, except by express written consent of the Administrative Agent, any
liability or responsibility for the performance of any duties or covenants of
any Obligor or Restricted Subsidiary.

      9.06. Expenditures. The Borrower shall reimburse Administrative Agent for
any reasonable sums spent by it in connection with the exercise of any Right
under Section 9.05 hereof. Such sums shall bear interest at the lesser of (a)
the Base Rate (whether or not in effect), plus 2.00% per annum and (b) the
Highest Lawful Rate, from 15 days after the date the Administrative Agent makes
demand to the Borrower for reimbursement of such amount until the date of
repayment by the Borrower.

                                       83
<PAGE>
 
      9.07. Control.  None of the covenants or other provisions contained in
this Agreement shall, or shall be deemed to, give Administrative Agent or any
Lender any Rights to exercise control over the affairs and/or management of any
of the Borrower or any of its Subsidiaries being limited to the Rights to
exercise the remedies provided in this Article; provided, however, that if
                                                --------  -------         
Administrative Agent or any Lender becomes the owner of any partnership, stock
or other equity interest in any Person, whether through foreclosure or
otherwise, it shall be entitled to exercise such legal Rights as it may have by
being an owner of such stock or other equity interest in such Person.


                      ARTICLE X. THE ADMINISTRATIVE AGENT

      10.01. Authorization and Action. Each Lender hereby appoints and
authorizes Administrative Agent to take such action as Administrative Agent
deems necessary on its behalf and to exercise such powers under this Agreement
and the other Loan Papers as are delegated to the Administrative Agent by the
terms of the Loan Papers, together with such powers as are reasonably incidental
thereto. As to any matters not expressly provided for by this Agreement and the
other Loan Papers (including without limitation enforcement or collection of the
Notes), Administrative Agent shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of Majority Lenders (or all Lenders, if required under Section
11.01 hereof), and such instructions shall be binding upon all Lenders;
provided, however, that Administrative Agent shall not be required to take any
- --------  -------                                                             
action which exposes Administrative Agent to personal liability or which is
contrary to any Loan Papers or applicable Law.  Administrative Agent agrees to
give to each Lender (a) notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement, (b) copies of all information delivered
to the Administrative Agent in accordance with the terms of Sections 7.01, 7.02
and 7.03 hereof and (c) to promptly distribute to each applicable Lender in like
funds all amounts delivered to Administrative Agent by the Borrower for the
individual account of any Lender pro rata in accordance with the Applicable
Specified Percentage, as set forth in this Agreement.  Functions of the
Administrative Agent are administerial in nature and in no event shall the
Administrative Agent have a fiduciary or trustee relationship in respect of any
Lender by reason of this Agreement or any other Loan Paper.

      10.02. Administrative Agent's Reliance, Etc. Neither Administrative Agent,
nor any of its directors, officers, agents, employees, or representatives shall
be liable for any action taken or omitted to be taken by it or them under or in
connection with this Agreement or any other Loan Paper, except for its or their
own gross negligence or willful misconduct. Without limitation of the generality
of the foregoing, Administrative Agent (a) may treat the payee of any Note as
the holder thereof until Administrative Agent receives written notice of the
assignment or transfer thereof signed by such payee and in form satisfactory to
Administrative Agent; (b) may consult with legal counsel (including counsel for
the Borrower or any of the Restricted Subsidiaries), independent public
accountants, and other experts reasonably selected by it, and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants, or experts; (c) makes
no warranty or representation to any Lender and shall not be responsible to any
Lender for any statements, warranties, or representations made in or in
connection with this Agreement or any other Loan Papers; (d) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants, or conditions of this Agreement or any other Loan Papers
on the part of the Borrower or the Restricted Subsidiaries or to inspect the

                                       84
<PAGE>
 
Property (including the books and records) of the Borrower or its Subsidiaries;
(e) shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency, or value of this Agreement,
any other Loan Papers, or any other instrument or document furnished pursuant
hereto; and (f) shall incur no liability under or in respect of this Agreement
or any other Loan Papers by acting upon any notice, consent, certificate, or
other instrument or writing believed by it to be genuine and signed or sent by
the proper party or parties.

      10.03. NationsBank, N.A. and Affiliates.  With respect to its Revolver A
Commitment, Working Line Commitment, Swingline Commitment, Revolver B
Commitment, its Advances, and any Loan Papers, NationsBank, N.A. has the same
Rights under this Agreement as any other Lender and may exercise the same as
though it were not Administrative Agent.  NationsBank, N.A. and its Affiliates
may accept deposits from, lend money to, act as trustee under indentures of, and
generally engage in any kind of business with, any Obligor, any Restricted
Subsidiary, any Affiliate thereof, and any Person who may do business therewith,
all as if NationsBank, N.A. were not Administrative Agent and without any duty
to account therefor to any Lender, including, without limitation, the TROL
Transaction.

      10.04. Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon Administrative Agent or any other
Lender, and based on the financial statements referred to in Section 5.01(j),
Section 7.01 and Section 7.02 hereof and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  Each Lender also acknowledges that it will, independently
and without reliance upon Administrative Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and the other Loan Papers.

      10.05. Indemnification by Lenders. Lenders shall indemnify Administrative
Agent, pro rata in accordance with each Lender's Total Specified Percentage,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, reasonable costs and expenses, or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against Administrative Agent in any way relating to or arising
out of any Loan Papers or any action taken or omitted by Administrative Agent
thereunder, including any negligence of Administrative Agent; provided, however,
                                                              --------  ------- 
that no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements resulting from Administrative Agent's gross negligence or willful
misconduct.  Without limitation of the foregoing, Lenders shall reimburse
Administrative Agent, pro rata in accordance with each Lender's Total Specified
Percentage, promptly upon demand for any out-of-pocket expenses (including
reasonable attorneys' fees) incurred by Administrative Agent in connection with
the preparation, execution, delivery, administration, modification, amendment,
or enforcement (whether through negotiation, legal proceedings or otherwise) of,
or legal and other advice in respect of rights or responsibilities under, the
Loan Papers.  The indemnity provided in this Section 10.05 shall survive the
termination of this Agreement.

      10.06. Successor Administrative Agent. Administrative Agent may resign at
any time by giving 30 days written notice thereof to Lenders and the Borrower,
and may be removed at any time with or without cause by the action of all of the
Lenders (other than Administrative Agent, if it is a Lender). If the
Administrative Agent also then serves in the capacity of the Swingline Bank or
the Letter of Credit issuing bank, such resignation or removal shall constitute
resignation or removal of 

                                       85
<PAGE>
 
the Swingline Bank and the Administrative Agent in its capacity of Letter of
Credit issuing bank and the successor Administrative Agent shall serve in the
capacity of the Swingline Bank and the Letter of Credit issuing bank, provided
that, the Administrative Agent agrees that if it voluntarily resigns as
Administrative Agent, the Borrower shall have up to 180 days to reissue the
existing Letters of Credit. Upon any such resignation or removal, Majority
Lenders shall have the right to appoint a successor Administrative Agent with
the prior written consent of the Borrower (which shall not be unreasonably
withheld), provided that, if there exists an Event of Default that is
continuing, no consent of the Borrower shall be required. If no successor
Administrative Agent shall have been so appointed and shall have accepted such
appointment within thirty days after the retiring Administrative Agent's giving
of notice of resignation, then the retiring Administrative Agent may, on behalf
of Lenders, appoint a successor Administrative Agent, which shall be a
commercial bank organized under the Laws of the United States of America or of
any State thereof and having a combined capital and surplus of at least
$500,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the Rights and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations under the Loan Papers,
provided that if the retiring or removed Administrative Agent is unable to
appoint a successor Administrative Agent, Administrative Agent shall, after the
expiration of a sixty day period from the date of notice, be relieved of all
obligations as Administrative Agent hereunder. Notwithstanding any
Administrative Agent's resignation or removal hereunder, the provisions of this
Article shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement.

                          ARTICLE XI.  MISCELLANEOUS

     11.01. Amendments and Waivers. No amendment or waiver of any provision of

Borrower or any Obligor or Restricted Subsidiary therefrom, shall be effective

   (iii) If to any Lender, to its address shown opposite its signature block on
the signature pages hereto, or on any Assignment and Acceptance, or in any other
notice to the Borrower and the Administrative Agent,

or at such other address or, telecopier or telephone number or to the attention
of such other individual or department as the party to which such information
pertains may hereafter specify for the purpose in a notice to the other
specifically captioned "Notice of Change of Address".

   (c) Effectiveness. Each notice to be given or delivered to any party pursuant
to this Agreement shall be effective or deemed delivered or furnished (i) if
sent by mail upon receipt, (ii) if sent by telecopier, when such notice is
transmitted to the appropriate number, answerback received, (iii) if sent by
hand delivery or overnight courier, when received by the addressee addressed as
above provided, and (iv) if given by telephone, when communicated to the
individual or any member of the department specified as the individual or
department to whose attention notices, communications and materials are to be
given or delivered except that notices of a change of address, telecopier or
telephone number or individual or department to whose attention notices,
communications and materials are to be given or delivered shall not be effective
until received; provided, however, that notices to Administrative Agent pursuant
                --------  -------                                               
to Article II shall be effective when received.  The Borrower agrees that
Administrative Agent shall have no duty or obligation to verify or otherwise
confirm telephonic notices given pursuant to Article II, and agrees to indemnify
and hold harmless Administrative Agent and Lenders for any and all liabilities,
obligations, losses, 

                                       88
<PAGE>
 
damages, penalties, actions, judgments, suits, claims, costs, and expenses
resulting, directly or indirectly, from acting upon any such notice.

     11.03. Parties in Interest. All covenants and agreements contained in this
Agreement and all other Loan Papers shall bind and inure to the benefit of the
respective successors and permitted assigns of the parties hereto. Each Lender
may from time to time assign or transfer its interests hereunder pursuant to
Section 11.04 hereof. The Borrower may not assign or transfer its Rights or
obligations hereunder without the prior written consent of each Lender.

     11.04. Assignments and Participations.

     (a) Each Lender (an "Assignor") may assign its Rights and obligations as a
Lender under the Loan Papers to another Lender or its Bank Affiliate, or to one
or more transferees pursuant to an Assignment and Acceptance, so long as, if
such Assignee is not another Lender or a Bank Affiliate of the Assignor (i) each
assignment shall be of a constant, and not a varying percentage of all Rights
and obligations thereunder, (ii) each Assignor shall obtain in each case the
prior written consent of Administrative Agent and the Borrower, such consent of
the Borrower not to be unreasonably withheld or delayed, provided that, in the
event there exists an Event of Default that is continuing, no consent of the
Borrower shall be required to make an assignment, (iii) each Assignor shall in
each case pay a $3,500 processing fee to Administrative Agent and (iv) no such
assignment is for an amount less than $10,000,000 (unless such Lender is
assigning all of its remaining interest) and in increments of $1,000,000 (and,
if such assignment is a partial assignment, no Lender shall hold less than
$10,000,000 immediately after giving effect to any assignment unless it assigned
all of its interest).  Assignments and other transfers (except participations)
with respect to each Lender's participation in a given Letter of Credit may only
be made with the prior written consent of the Administrative Agent.  Within five
Business Days after the Borrower receives notice of any such assignment, the
Borrower shall execute and deliver to Administrative Agent, but only in exchange
for the Notes issued to Assignor, new Notes to the order of such Assignor and
its assignee in amounts equal to their respective Applicable Specified
Percentages of the Revolver A Commitment and the Revolver B Commitment (if any
exists), and/or the Working Line Commitment, or after the Conversion Date (if
any), the amount of the Working Line Loan, as applicable.  Such new Notes shall
be dated the effective date of the assignment.  It is specifically acknowledged
and agreed that on and after the effective date of each assignment, the assignee
shall be a party hereto and shall have the Rights and obligations of a Lender
under the Loan Papers.

     (b) Each Lender may sell participations to one or more Persons in all or
any of its Rights and obligations under the Loan Papers; provided, however, that
                                                         --------  ------- 
(i) such Lender's obligations under the Loan Papers shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) such Lender shall remain the holder of
its Notes for all purposes of the Loan Papers, (iv) the participant shall be
granted the Right to vote on or consent to only those matters described in
Sections 11.01(a), (b), (c), (d) and (e) hereof, (v) Obligors, the Restricted
Subsidiaries, the Administrative Agent, and other Lenders shall continue to deal
solely and directly with such Lender in connection with their respective Rights
and obligations under the Loan Papers and (vi) no such participation is for an
amount less than $5,000,000.

    (c) Any Lender may, in connection with any assignment or participation, or
proposed assignment or participation, disclose to the assignee or participant,
or proposed assignee or 

                                       89
<PAGE>
 
participant, any information relating to the Borrower and its Subsidiaries
furnished to such Lender by or on behalf of the Borrower and its Subsidiaries,
subject to the provisions of Section 11.15 hereof.

     (d) Notwithstanding any other provision set forth in this Agreement, (i)
any Lender may at any time create a security interest in all or any portion of
its Rights under this Agreement (including, without limitation, the Advances
owing to it and the Notes held by it) in favor of any Federal Reserve Bank in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System and (ii) no participant of any Lender may further assign or participate
any of its interest in the Loan Papers to any Person (except as may be required
by Law or a Tribunal having authority over such participant).

     11.05. Sharing of Payments.  If, after and during the continuance of any
Event of Default,  any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any Right of set-off, or otherwise) on
account of its Advances in excess of its pro rata share of payments made by the
Borrower in accordance with such Lender's Total Specified Percentage (except
payments to the Swingline Bank made to repay Swingline Advances), such Lender
shall forthwith purchase participations in Advances made by the other Lenders as
shall be necessary to share the excess payment pro rata in accordance with each
Lender's Total Specified Percentage with each of them; provided, however, that
                                                       --------  -------      
if any of such excess payment is thereafter recovered from the purchasing
Lender, its purchase from each Lender shall be rescinded and each Lender shall
repay the purchase price to the extent of such recovery together with a pro rata
share of any interest or other amount paid or payable by the purchasing Lender
in respect of the total amount so recovered.  The Borrower agrees that any
Lender so purchasing a participation from another Lender pursuant to this
Section 11.05 may, to the fullest extent permitted by Law, exercise all its
Rights of payment (including the Right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation.

     11.06. Right of Set-off. Upon the occurrence and during the continuance of
any Event of Default, each Lender is hereby authorized (after prior written
notice to the Administrative Agent) at any time and from time to time, to the
fullest extent permitted by Law, to set-off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower or any of its Restricted Subsidiaries against any and
all of the obligations of the Borrower now or hereafter existing under this
Agreement and the other Loan Papers, whether or not Administrative Agent or any
Lender shall have made any demand under this Agreement or the other Loan Papers,
and even if such obligations are unmatured. Each Lender shall promptly notify
the Borrower after any such set-off and application, provided that the failure
to give such notice shall not affect the validity of such set-off and
application. The Rights of each Lender under this Section 11.06 are in addition
to other Rights (including, without limitation, other Rights of set-off) which
such Lender may have.

                                       90
<PAGE>
 
     11.07. Costs, Expenses, and Taxes.

     (a) Notwithstanding anything to the contrary in the Loan Papers, the
Borrower agrees to pay on demand (i) all reasonable out of pocket costs and
expenses of Administrative Agent, Co-Arrangers, Co-Syndication Agents and the
Arranging Agents in connection with the preparation and negotiation of all Loan
Papers, including without limitation the reasonable fees and out-of-pocket
expenses of Special Counsel, FCC counsel, PUC counsel and local counsel, as
appropriate, (ii) all costs and expenses (including reasonable attorneys' fees
and expenses) of Administrative Agent and Arranging Agents in connection with
any interpretation, grant and perfection of any Lien, modification, amendment,
waiver, release of any Loan Papers, restructuring or work-out and (iii) all
costs and expenses (including reasonable attorneys' fees and expenses) of
Administrative Agent, the other Arranging Agents and each Lender in connection
with any collection of any portion of the Obligations or the enforcement of any
Loan Papers during the continuance of an Event of Default.

     (b) In addition, notwithstanding anything to the contrary in the Loan
Papers, the Borrower shall pay any and all stamp, debt, and other Taxes payable
or determined to be payable in connection with any payment hereunder to
Administrative Agent, Arranging Agents or any Lender (but specifically excluding
any participant) (other than Taxes on the overall net income of Administrative
Agent or any Lender or franchise Taxes or Taxes on capital or capital receipts
of Administrative Agent or any Lender), or the execution, delivery, or
recordation of any Loan Papers, and agrees to save Administrative Agent and each
Lender harmless from and against any and all liabilities with respect to, or
resulting from any delay in paying or omission to pay any Taxes in accordance
with this Section 11.07, including any penalty, interest, and expenses relating
thereto.  All payments by the Borrower or any Restricted Subsidiary of the
Borrower under any Loan Papers shall be made free and clear of and without
deduction for any present or future Taxes (other than Taxes on the overall net
income of Administrative Agent or any Lender of any nature now or hereafter
existing, levied, or withheld, or franchise Taxes or Taxes on capital or capital
receipts of Administrative Agent or any Lender), including all interest,
penalties, or similar liabilities relating thereto.  If the Borrower shall be
required by Law to deduct or to withhold any Taxes from or in respect of any
amount payable hereunder (i) the amount so payable shall be increased to the
extent necessary so that, after making all required deductions and withholdings
(including Taxes on amounts payable to Administrative Agent or any Lender
pursuant to this sentence), Administrative Agent or any Lender receives an
amount equal to the sum it would have received had no such deductions or
withholdings been made, (ii) the Borrower shall make such deductions or
withholdings, and (iii) the Borrower shall pay the full amount deducted or
withheld to the relevant taxing authority in accordance with applicable Law.
Without prejudice to the survival of any other agreement of the Borrower
hereunder, the agreements and obligations of the Borrower contained in this
Section 11.07 shall survive the execution of this Agreement, termination of the
Commitment, repayment of the Obligations, satisfaction of each agreement
securing or assuring the Obligations and termination of this Agreement and each
other Loan Paper.

     11.08. Rate Provision.  It is not the intention of any party to any Loan
Papers to make an agreement violative of the Laws of any applicable jurisdiction
relating to usury.  In no event shall any Obligor, Restricted Subsidiary or any
other Person be obligated to pay any amount in excess of the Maximum Amount.  If
Administrative Agent or any Lender ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest shall
be deemed a partial repayment of principal and treated hereunder as such; and if
principal is paid in full, any remaining excess shall be paid to the Borrower or
the other Person entitled thereto.  In determining 

                                       91
<PAGE>
 
whether or not the interest paid or payable, under any specific contingency,
exceeds the Maximum Amount, each Obligor, Restricted Subsidiary, Administrative
Agent and each Lender shall, to the maximum extent permitted under Applicable
Laws, (a) characterize any nonprincipal payment as an expense, fee or premium
rather than as interest, (b) exclude voluntary prepayments and the effect
thereof, and (c) amortize, prorate, allocate and spread in equal parts, the
total amount of interest throughout the entire contemplated term of the
Obligations so that the interest rate is uniform throughout the entire term of
the Obligations; provided that if the Obligations are paid and performed in full
                 --------                        
prior to the end of the full contemplated term thereof, and if the interest
received for the actual period of existence thereof exceeds the Maximum Amount,
Administrative Agent or Lenders, as appropriate, shall refund to the Borrower
the amount of such excess or credit the amount of such excess against the total
principal amount owing, and, in such event, to the extent permitted by
Applicable Law, neither Administrative Agent nor any Lender shall be subject to
any penalties provided by any Laws for contracting for, charging or receiving
interest in excess of the Maximum Amount. This Section 11.08 shall control every
other provision of all agreements among the parties to the Loan Papers
pertaining to the transactions contemplated by or contained in the Loan Papers.

     11.09. Severability.  If any provision of any Loan Paper is held to be
illegal, invalid, or unenforceable under present or future Laws during the term
thereof, such provision shall be fully severable, the appropriate Loan Paper
shall be construed and enforced as if such illegal, invalid, or unenforceable
provision had never comprised a part thereof, and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by the
illegal, invalid, or unenforceable provision or by its severance therefrom.
Furthermore, in lieu of such illegal, invalid, or unenforceable provision there
shall be added automatically as a part of such Loan Paper a legal, valid, and
enforceable provision substantially similar in terms to the illegal, invalid, or
unenforceable provision as may be possible.

     11.10. Exceptions to Covenants. No Obligor or Restricted Subsidiary shall
be deemed to be permitted to take any action or to fail to take any action that
is permitted as an exception to any covenant in any Loan Papers, or that is
within the permissible limits of any covenant, if such action or omission would
result in a violation of any other covenant in any Loan Papers.

     11.11. Counterparts. This Agreement and the other Loan Papers may be
executed in any number of counterparts with different parties signing on
different counterparts, all of which taken together shall constitute one and the
same instrument. In making proof of any such agreement, it shall not be
necessary to produce or account for any counterpart other than one signed by the
party against which enforcement is sought.

     11.12. GOVERNING LAW; WAIVER OF JURY TRIAL.

     (a)    THIS AGREEMENT AND ALL OTHER LOAN PAPERS SHALL BE DEEMED TO BE
CONTRACTS MADE IN NEW YORK, NEW YORK, AND SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AND THE UNITED STATES OF
AMERICA. WITHOUT EXCLUDING ANY OTHER JURISDICTION, THE BORROWER AGREES TO SUBMIT
ITSELF TO THE JURISDICTION OF THE FEDERAL COURTS OF NEW YORK LOCATED IN NEW
YORK, NEW YORK FOR PROCEEDINGS IN CONNECTION HEREWITH. TO THE MAXIMUM EXTENT
PERMITTED BY LAW, THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER HEREBY
WAIVES ANY RIGHT 

                                       92
<PAGE>
 
THAT IT MAY HAVE TO A TRIAL BY JURY OF ANY DISPUTE (WHETHER A CLAIM IN TORT,
CONTRACT, EQUITY, OR OTHERWISE) ARISING UNDER OR RELATING TO THIS AGREEMENT, THE
OTHER LOAN PAPERS, OR ANY RELATED MATTERS, AND AGREES THAT ANY SUCH DISPUTE
SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A JURY.

     (b)    THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER HEREBY WAIVES
PERSONAL SERVICE OF ANY LEGAL PROCESS UPON IT.  THE BORROWER, THE ADMINISTRATIVE
AGENT AND EACH LENDER AGREES THAT SERVICE OF PROCESS MAY BE MADE UPON IT BY
REGISTERED MAIL (RETURN RECEIPT REQUESTED) DIRECTED TO THE BORROWER, THE
ADMINISTRATIVE AGENT OR EACH SUCH LENDER, RESPECTIVELY, AT ITS ADDRESS
DESIGNATED FOR NOTICE UNDER THIS AGREEMENT.   NOTHING IN THIS SECTION 11.12
SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW.

     11.13. ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN PAPERS REPRESENT
THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE
OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENT OF THE PARTIES. THERE ARE
NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. THIS AGREEMENT SUPERSEDES AND
REPLACES IN ITS ENTIRETY THE LETTER AGREEMENT DATED FEBRUARY 2, 1999, INCLUDING,
WITHOUT LIMITATION, THE SUMMARY OF TERMS AND CONDITIONS DATED FEBRUARY 2, 1999.
 
     11.14. Release of Conditional Early Release Unlimited Guaranty. At such
time as (i) there exists no Default under Section 9.01(a) hereof, (ii) there
exists no Event of Default and (iii) the Senior Unsecured Debt Rating is BBB- or
Baa3 or better, the Guarantor shall be immediately and automatically released
from its obligations under the Conditional Early Release Unlimited Guaranty, and
the Administrative Agent shall, and the Arranging Agents and the Lenders hereby
authorize the Administrative Agent to, promptly take all action and execute such
documents to release LCI International, Inc. from its obligations under the
Conditional Early Release Unlimited Guaranty in full, and return the Conditional
Early Release Unlimited Guaranty to LCI International, Inc.

     11.15. Confidentiality. Each Lender agrees to keep information obtained by
it pursuant to the terms hereof or the terms of any other Loan Paper that is not
otherwise publicly available ("Confidential Information") confidential in
accordance with such Lender's customary procedures for handling confidential
information of this nature and in accordance with safe and sound banking
practices and agrees that it will only use such Confidential Information in
connection with the transactions contemplated by this Agreement and not disclose
any of such Confidential Information other than (a) to such Lenders and its
Affiliates' (other than an Affiliate which is a competitor of the Borrower or
its Subsidiaries) employees, counsel (in-house and outside), accountants,
consultants, representatives, professional advisors and agents so long as such
Person is advised of the confidentiality of such Confidential Information and
the limitation on its use under this Section 11.15, needs to have knowledge of
such Confidential Information for such limited use, and, if such Person is not
such Lenders' or its Affiliates' employee, counsel (in-house and outside),
accountant consultant, professional advisor or agent, such Person has executed a
confidentiality undertaking in favor of the Borrower substantially upon the
terms of this Section 11.15 before such Confidential 

                                       93
<PAGE>
 
Information is disclosed to such Person, (b) to regulatory officials, and in
order to comply with any Applicable Law, or other law, regulation or judicial
order, or as requested or required by bank regulators or auditors or other
governmental authorities or Tribunals, (c) as reasonably deemed necessary in
connection with any investigation, legal process or litigation, or (d) to
assignees or participants or proposed assignees or proposed participants of all
or any part of this credit facility so long as such Person has executed a
confidentiality undertaking in favor of the Borrower substantially upon the
terms of this Section 11.15 before such Confidential Information is disclosed to
such Person. The failure of any Lender to comply with the provisions of this
Section 11.15 shall not affect the Obligations, or the obligation of the
Borrower to comply with the terms of this Agreement and the other Loan Papers,
or the validity of any assignment or participation granted pursuant to the terms
of this Agreement. Each Lender shall be responsible for any breach of the
provisions of this Section 11.15 or unauthorized disclosure of such Confidential
Information by any of its or its Affiliates' employees, counsel (in-house and
outside), accountants, consultants, representatives, professional advisors and
agents. Each Lender shall take customary precautions to prevent Confidential
Information from being disclosed to its employees or employees of any Affiliate
who are equity analysts or Persons involved in publication of research in
connection with the Borrower or any of the Borrower's Subsidiaries or any of
their respective securities.
