              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                 THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2001
                                  (UNAUDITED)

NOTE 1: BASIS OF PRESENTATION

     The condensed consolidated financial statements include the accounts of
Qwest Corporation ("Qwest" or "we" or "us" or "our") and our wholly owned
subsidiaries. On June 30, 2000, Qwest Communications International Inc. ("QCII")
completed its acquisition (the "Merger") of our parent company, U S WEST, Inc.
("U S WEST"). Each outstanding share of U S WEST common stock was converted into
the right to receive 1.72932 shares of QCII common stock. In addition, all
outstanding U S WEST stock options were converted into options to acquire QCII
common stock. The Merger was accounted for as a reverse acquisition under the
purchase method of accounting with U S WEST being deemed the accounting acquirer
and QCII the acquired entity. As U S WEST was deemed the accounting acquirer,
its historical financial statements have been carried forward as those of the
combined company. We are a wholly owned indirect subsidiary of QCII.

     The condensed consolidated interim financial statements are unaudited. We
prepared the financial statements in accordance with the instructions for Form
10-Q. In compliance with those instructions, certain information and footnote
disclosures normally included in the financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted. In
management's opinion, all adjustments (consisting only of normal recurring
adjustments) necessary to present fairly the consolidated results of operations,
financial position and cash flows as of September 30, 2001 and for all periods
presented were made. These financial statements should be read in conjunction
with the audited financial statements incorporated by reference in our Annual
Report on Form 10-K for the year ended December 31, 2000. The condensed
consolidated results of operations for the three and nine months ended September
30, 2001 are not necessarily indicative of the results expected for the full
year. We made certain reclassifications to previously reported balances to
conform with the current year presentation.

NOTE 2: MERGER-RELATED AND OTHER ONE-TIME CHARGES

     We consider only those costs that are incremental and directly related to
the Merger to be "Merger-related." For the three and nine months ended September
30, 2001 and 2000, we incurred the following Merger-related and other one-time
charges:

     For the nine months ended September 30, 2001, we incurred $137 million in
Merger-related and other one-time charges. These primarily consisted of
contractual settlements, severance and headcount-related charges and other
Merger-related and one-time charges. The severance and headcount-related charges
for the nine months ended September 30, 2001 covers a workforce reduction of
over 2,800 employees who were involuntarily terminated. Other Merger-related and
one-time charges included professional fees, re-branding costs, asset impairment
charges and other costs related to the integration of U S WEST and QCII.

     For the three and nine months ended September 30, 2000, we incurred $899
million and $1.019 billion, respectively in Merger-related and other one-time
charges. These primarily consisted of contractual settle-

ments, severance and headcount charges resulting from payments to employees who
left the business upon the consummation of the Merger, retention bonus payments
that were subject to the successful completion of the Merger and property, plant
and equipment asset abandonments and impairments.

     A summary as of September 30, 2001 of Merger-related and other one-time

     We do not foresee any additional Merger-related charges and anticipate that
the majority of the contractual settlements, severance and other Merger-related
and one-time charge accruals will be paid by the end of the current fiscal year.
Legal contingencies will be paid as the related matters are resolved. When
matters are finalized, any differences between amounts accrued and actual
payments will be reflected in results of operations as an adjustment to
Merger-related and other one-time charges.

NOTE 3: ACCESS LINES RETURNED TO SERVICE

     During 1999 and 2000, U S WEST committed to sell approximately 800,000
access lines to third-party telecommunications service providers, including
approximately 570,000 access lines to Citizens Communications Company
("Citizens"). Because these access lines were "held for sale," we discontinued
recognizing depreciation expense on these assets and recorded them at the lower
of their cost or fair value, less estimated cost to sell.

     On July 20, 2001, we terminated our agreement with Citizens under which the
majority of the access lines were to have been sold and ceased actively
marketing the remaining lines. As a result, the access lines were reclassified
as being "held for use" as of June 30, 2001. The access lines were measured
individually at the lower of their (a) carrying value before they were
classified as held for sale, adjusted for any depreciation (amortization)
expense or impairment losses that would have been recognized had the assets been
continuously classified as held for use, or (b) their fair value at June 30,
2001. The required adjustments to the carrying value of the individual access
lines are included in income from continuing operations for the nine months
ended September 30, 2001. This resulted in a charge to depreciation of $222
million.

     In April 2001, we sold approximately 38,000 access lines resulting in a
gain for the nine months ended September 30, 2001 of $50 million.

NOTE 4: SEGMENT INFORMATION

     We operate in three segments: retail services, wholesale services and
network services. The retail services segment provides local telephone services,
long-distance services, wireless services and data services. The wholesale
services segment provides exchange access services that connect customers to the
facilities of interexchange carriers ("IXCs") and interconnection to our
telecommunications network to competitive local exchange carriers ("CLECs"). The
network services segment provides access to our telecommunications network,
including our information technologies, primarily to our retail services and
wholesale services segments. We provide our services to more than 25 million
residential and business customers in Arizona, Colorado, Idaho, Iowa, Minnesota,
Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah,
Washington and Wyoming (our "local service area").

     Following is a breakout of our segments, which we extracted from the
financial statements of QCII. Certain revenue and expenses of QCII are included
in the segment data, which we eliminated in the reconciling items column.
Additionally, because significant expenses of operating the retail services and
wholesale services segments are not allocated to such segments for decision
making purposes, management does not believe the segment margins are
representative of the actual operating results of the segments for Qwest. The
margin for the retail services and wholesale services segments excludes network
and corporate expenses. The margin for the network services segment excludes
corporate expenses. The "other" category includes unallocated corporate expenses
and revenues. Asset information by segment is not provided to our chief
operating decision-maker. The communications and related services column
represents the total of the retail services, wholesale services and network
services segments. The figures presented below for the three and nine months
ended September 30, 2000 have been adjusted to reflect certain reclassifications
to conform with the presentation of the corresponding periods of 2001.

NOTE 5: CONTINGENCIES

     Through September 2001, seven purported class action complaints had been
filed in various state courts against us and U S WEST on behalf of customers in
the states of Arizona, Colorado, Minnesota, New Mexico, Oregon, Utah and
Washington. The complaints alleged, among other things, that from 1993 to the
present, U S WEST, in violation of alleged statutory and common law obligations,
willfully delayed the provision of local telephone service to the purported
class members. The complaints also alleged that U S WEST misrepresented the date
on which such local telephone service was to be provided to the purported class
members. The complaints sought compensatory damages for purported class members,
disgorgement of profits and punitive damages. The parties have signed agreements
to settle the complaints. As of September 2001, the settlements have been
approved by all of the courts.

     On July 23, 2001, we filed a demand for arbitration against Citizens
alleging that it breached Agreements for Purchase and Sale of Telephone
Exchanges dated as of June 16, 1999, between Citizens Utilities Company and U S
WEST Communications, Inc., with respect to the purchase and sale of exchanges in
Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska and Wyoming. The
demand for arbitration was filed after Citizens failed to close the exchange
sales in violation of the terms of the Purchase Agreements. Citizens in turn
filed a demand alleging claims against us in connection with the sale of those
same exchanges. In the arbitration, we seek a determination that Citizens
breached the agreements and, as a result, we are entitled to retain the letters
of credit Citizens provided in connection with the transactions and other
damages. Citizens seeks a determination that we breached the agreements and, as
a result, they are entitled to damages. This dispute is still at a preliminary
stage.

     Various other litigation matters have been filed against us. We intend to
vigorously defend these outstanding claims.

     We have provided for the above matters in our condensed consolidated
financial statements as of September 30, 2001. We do not expect any material
adverse impacts in excess of such provision as a result of the ultimate
resolution of these matters.

NOTE 6: NEW ACCOUNTING STANDARDS

     In June 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 141, "Business
Combinations." This pronouncement eliminated the use of the "pooling of
interests" method of accounting for all mergers and acquisitions. As a result,
all mergers and acquisitions will be accounted for using the "purchase" method
of accounting. SFAS No. 141 is effective for all mergers and acquisitions
initiated after June 30, 2001. Adoption of this pronouncement has no impact on
our results from operations or our financial position.

     In June 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible
Assets." This statement addresses financial accounting and reporting for
intangible assets (excluding goodwill) acquired individually or with a group of
other assets at the time of their acquisition. It also addresses financial
accounting and reporting for goodwill and other intangible assets subsequent to
their acquisition. Intangible assets (excluding goodwill) acquired outside of a
business combination will be initially recorded at their estimated fair value.
If the intangible asset has a finite useful life, it will be amortized over that
life. Intangible assets with an indefinite life are not amortized. Both types of
intangible assets will be reviewed annually for impairment and a loss recorded
when the asset's carrying amount exceeds its estimated fair value. Goodwill will
be treated similar to an intangible asset with an indefinite life. SFAS No. 142
is effective for fiscal years beginning after December 15, 2001. The adoption of
SFAS No. 142 will have no impact on our consolidated financial results.

     In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations." This statement deals with the costs of closing
facilities and removing assets. SFAS No. 143 requires entities to record the
fair value of a legal liability for an asset retirement obligation in the period
it is incurred. This cost is initially capitalized and amortized over the
remaining life of the underlying asset. Once the obligation is ultimately
settled, any difference between the final cost and the recorded liability is
recognized as a gain or loss on disposition. SFAS No. 143 is effective for years
beginning after June 15, 2002. We are currently evaluating the impact this
pronouncement will have on our future consolidated financial results.

     In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets." This pronouncement addresses how
to account for and report impairments or disposals of long-lived assets. Under
SFAS No. 144, an impairment loss is to be recorded on long-lived assets being
held or used when the carrying amount of the asset is not recoverable from its
undiscounted cash flows. The impairment loss is equal to the difference between
the asset's carrying amount and estimated fair value. Long-lived assets to be
disposed of by other than a sale for cash are to be accounted for and reported
like assets being held or used except the impairment loss is recognized at the
time of the disposition. Long-lived assets to be disposed of by sale are to be
recorded at the lower of their carrying amount or estimated fair value (less
costs to sell) at the time the plan of disposition has been approved and
committed to by the appropriate company management. In addition, depreciation is
to cease at the same time. SFAS No. 144 is effective for fiscal years beginning
after December 15, 2001. We are currently evaluating the impact this
pronouncement will have on our future consolidated financial results.

     - the duration and extent of the current economic downturn;

     - adverse economic conditions in the markets served by us;

     - dependence on new product development and acceleration of the deployment
       of advanced new services, such as broadband data, wireless and video
       services, which could require substantial expenditure of financial and
       other resources in excess of contemplated levels;

     - higher than anticipated employee levels, capital expenditures and
       operating expenses;

     - rapid and significant changes in technology and markets;

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

     - delays in Qwest's ability to provide interLATA services within its
       14-state local service area; and

     - failure to achieve the projected synergies and financial results expected
       to result from the acquisition of U S WEST, Inc. ("U S WEST"), by Qwest
       Communications International Inc. ("QCII") on June 30, 2000 (the
       "Merger"), and difficulties in combining the operations of the combined
       company, which could affect our revenues, levels of expenses and
       operating results.

RESULTS OF OPERATIONS

  Three and Nine Months Ended September 30, 2001 Compared with 2000

     Certain non-recurring items impacted net income during the three months
ended September 30, 2000 and the nine months ended September 30, 2001 and 2000.
Results of operations for the three and nine months ended September 30, 2001 and
2000 excluding the effects of non-recurring items are as follows:

Non-recurring items in 2001 and 2000 include:

     - an after-tax charge of $551 million ($899 million, pre-tax) for the three
       months ended September 30, 2000 for Merger-related and other one-time
       charges (see Note 2: "Merger-Related and Other One-Time Charges" -- to
       the condensed consolidated financial statements)

     - an after-tax charge of $84 million and $625 million ($137 million and
       $1.019 billion, pre-tax, respectively) for the nine months ended
       September 30, 2001 and 2000, respectively, for Merger-related and other
       one-time charges (see Note 2: "Merger-Related and Other One-Time
       Charges" -- to the condensed consolidated financial statements)

     - an after-tax charge of $136 million ($222 million, pre-tax) for the nine
       months ended September 30, 2001 for depreciation associated with access
       lines returned to service (see Note 3: "Access Lines Returned to
       Service" -- to the condensed consolidated financial statements)

     - an after-tax gain of $30 million ($50 million, pre-tax) for the nine
       months ended September 30, 2001 for the sale of access lines

     - an after-tax loss of $24 million ($39 million, pre-tax) for the three and
       nine months ended September 30, 2000 for the sale of fixed assets.

     Adjusted net income for the three months ended September 30, 2001 was
relatively flat compared to the same period for 2000. Higher depreciation as a
result of increased capital expenditures for our network was almost entirely
offset by synergy cost savings associated with the Merger. Adjusted net income
for the nine months ended September 30, 2001 increased by $178 million or 12.4%
over the comparable period in 2000. The increase was primarily due to revenue
growth associated with increased demand for our wireless and data services,
lower employee benefit costs such as pension and post-retirement and cost
savings associated with synergies generated by the Merger. Partially offsetting
these items were higher operating costs driven by growth initiatives and higher
depreciation associated with the continued investment in our network facilities.

  REVENUES

     Commercial services revenues are derived from sales of Internet, data,
voice and wireless products and services to both retail and wholesale business
customers. The decrease in commercial services revenues for the three months
ended September 30, 2001 versus the same period in 2000 was primarily
attributable to a decline in local service revenues due to a slowing economy,
competitive losses and technology displacement. Partially offsetting the
decrease was growth in sales of data products and services such as private line
and digital subscriber line ("DSL"). The increase in commercial services
revenues for the nine months ended September 30, 2001 as compared to the nine
months ended September 30, 2000 was due principally to higher revenue from sales
of data products and services such as private line, frame relay and DSL. We
believe revenues from data products and services will account for an
increasingly larger portion of commercial services revenue in future periods.

     Consumer and small business services revenues are derived from sales of
Internet, data, voice and wireless products and services to the consumer and
small business markets. The increases in consumer and small business services
revenues for the three and nine months ended September 30, 2001 as compared to
the same periods in 2000, were primarily attributable to growth in revenues from
the increased sales of wireless services and products. Wireless products and
services revenue in the three- and nine-month periods ended September 30, 2001
grew by 68% and 55% respectively, over the three- and nine-month periods ended
September 30, 2000. Average revenue per user increased for the second straight
quarter, increasing from $52 in the second quarter of 2001 to $55 in the third
quarter as we continued to focus on high-value customers and exited the
low-usage, pre-paid business. In both the three and nine months ended September
30, 2001, data services revenue also continued to increase when compared to the
three and nine months ended September 30, 2000. For the three months ended
September 30, 2001 versus the three months ended September 30, 2000,

                                        11
<PAGE>

reductions in intraLATA toll revenue caused by increased competition offset some
of the increase in consumer and small business services revenue.

     Switched access services revenues are derived from inter- and intra-state
switched access from interexchange carriers ("IXCs"). The decreases in switched
access services revenues for the three and nine months ended September 30, 2001
as compared to the three and nine months ended September 30, 2000, were
principally attributable to increased competition and federal access reform that
reduced the rates we are able to collect for the switched access services. We
believe revenues from switched access services will continue to be negatively
impacted by federal access reform.

     Revenues for the foreseeable future may reflect the continuing impact of a
slowing local economy.

  OPERATING EXPENSES

     Employee-related expenses.  Employee-related expenses include salaries and
wages, benefits, payroll taxes and contract labor.

     Employee-related expenses increased for the three months ended September
30, 2001 as compared to the same period in 2000, primarily due to higher
employee benefit and contract labor costs. The higher expenses were partially
offset by lower costs associated with employee reductions. Employee-related
expenses for the nine months ended September 30, 2001 decreased from the
comparable period in 2000 primarily because of employee reductions. Partially
offsetting these lower costs was a decrease in the pension credit, net of other
post-retirement benefits. For the nine months ended September 30, 2001 and 2000,
pension credits, net of other post-retirement benefits, of $208 million and $223
million, respectively, were recorded. The decrease in employee-related expenses
associated with headcount reductions has been partially offset by the need to
increase employee levels in the growth sectors of our business, primarily
wireless and data communications. Additionally, increased commitments towards
improving customer service, including responding to requests for installation
and repair services, have resulted in the hiring of additional employees in
these specific areas.

     Other operating expenses.  Other operating expenses include access charges
paid to carriers for the routing of local and long-distance traffic through
their facilities, taxes other than income tax, uncollectible expenses and other
selling and general and administrative costs. The decreases in other operating
expenses for the three and nine months ended September 30, 2001 as compared to
the three and nine months ended September 30, 2000, were primarily attributable
to cost savings generated by the Merger such as the closure of redundant
facilities, operational synergies derived from the consolidation of core
operational units that provide common services and the leveraging of our
purchasing power throughout the Company, and a decline in access charges as the
result of a one-time refund. In addition, for the nine months ended September
30, 2001, there was a drop in our tax (other than income tax) obligations when
compared to the same period in 2000. Offsetting some of the decrease were
increases in uncollectible expenses, professional fees and costs associated with
the sales of data and wireless products and services.

     Depreciation and amortization expense.  The increases in depreciation and
amortization expense for the three and nine months ended September 30, 2001 as
compared to the same periods in 2000, were primarily attributable to a one-time
charge for access lines returned to service and higher overall property, plant
and equipment balances resulting from continued investment in our network to
meet forecasted demand and improve customer service.

     During 1999 and 2000, U S WEST committed to sell approximately 800,000
access lines to third-party telecommunications service providers, including
approximately 570,000 access lines to Citizens Communications Company
("Citizens"). Because these access lines were "held for sale," we discontinued
recognizing depreciation expense on these assets and recorded these assets at
the lower of their cost or fair value, less estimated cost to sell.

     On July 20, 2001, we terminated our agreement with Citizens under which the
majority of the remaining access lines were to have been sold and ceased
actively marketing the remaining lines. As a result, the remaining access lines
were reclassified as being "held for use" as of June 30, 2001. The access lines
were measured individually at the lower of their (a) carrying amount before they
were classified as held for sale,
                                        12
<PAGE>

adjusted for any depreciation (amortization) expense or impairment losses that
would have been recognized had the assets been continuously classified as held
for use, or (b) their fair value at June 30, 2001. The required adjustments to
the carrying amount of the individual access lines are included in income from
continuing operations for the nine months ended September 30, 2001. This
resulted in a charge to depreciation of $222 million.

     Merger-related and other one-time charges.  No Merger-related and other
one-time charges were incurred for the three months ended September 30, 2001.
For the nine months ended September 30, 2001, we incurred Merger-related and
other one-time charges totaling $137 million. The charge for the nine months
ended September 30, 2001 includes $34 million in contract settlements, $39
million of severance and headcount-related charges, $20 million in asset
impairment charges and $44 million of other Merger-related and one-time charges.
The severance charge for the nine months ended September 30, 2001 covers a
workforce reduction of over 2,800 employees who were involuntarily terminated.
Other Merger-related and one-time charges include professional fees, re-branding
costs and other costs related to the integration of U S WEST and QCII.

     We do not foresee any additional Merger-related charges and anticipate that
the contractual settlements, severance and other Merger-related and one-time
charge accruals will be paid by the end of the current fiscal year. Legal
contingencies will be paid as the related matters are resolved. When matters are
finalized, any differences between amounts accrued and actual payments will be
reflected in results of operations as an adjustment to Merger-related and other
one-time charges.

     Other expense - net.  Interest expense increased $3 million and $58
million for the three and nine months ended September 30, 2001, respectively,
over the same periods in 2000. The increases were due to higher average debt
balances to fund growth initiatives and network capital expenditures. For the
nine months ended September 30, 2001, we recognized a $50 million gain on the
sale of approximately 38,000 access lines in Utah. The remaining change for the
nine months ended September 30, 2001 was primarily attributable to interest
income on a federal income tax refund and a reduction in regulatory interest
expense. For the three and nine months ended September 30, 2000, we incurred a
$39 million loss on the sale of fixed assets.

     Provision for income taxes.  The effective tax rate for the three months
ended September 30, 2001 of 38.1% was lower than the effective tax rate for the
three months ended September 30, 2000 of 44.7%. The higher rate in 2000 was
primarily attributable to an increase in non-recurring expenses and other
permanent differences as compared to income before income taxes for the three
months ended September 30, 2000 versus the same period in 2001. The effective
tax rate for the nine months ended September 30, 2001 of 37.9% was consistent
with the effective tax rate for the nine months ended September 30, 2000 of
37.4%.

RECENT REGULATORY DEVELOPMENTS

     As a general matter, we are subject to substantial regulation, including
requirements and restrictions arising under the Telecommunication Act of 1996
(the "Act") and state utility laws, and the rules and policies of the Federal
Communications Commission ("FCC"), state Public Utility Commissions ("PUCs") and
other governmental entities. This regulation, among other matters, currently
prohibits us (with certain exceptions) from providing retail or wholesale
interLATA telecommunications services within our 14-state local service area,
and governs the terms and conditions under which we provide services to our
customers (including competing competitive local exchange carriers ("CLECs") and
IXCs in our local service area).

     Interconnection.  The FCC is continuing to interpret the obligations of
incumbent local exchange carriers ("ILECs") under the Act to interconnect their
networks with, and make unbundled network elements available to, CLECs. These
decisions establish our obligations in our local service area and our rights
when we compete outside of our local service area. In addition, the United
States Supreme Court is now considering an appeal from a ruling of the Eighth
Circuit Court of Appeals that the FCC's rules for the pricing of interconnection
and unbundled network elements by ILECs unlawfully preclude ILECs from
recovering their actual costs as required by the Act.

                                        13
<PAGE>

     Access Pricing.  The FCC has initiated a number of proceedings that
directly affect the rates and charges for access services that we sold or
purchased. It is expected that these proceedings and related implementation of
resulting FCC decisions will continue through 2002.

     On May 31, 2000, the FCC adopted the access reform and universal service
plan developed by the Coalition for Affordable Local and Long-Distance Service
("CALLS"). The adoption of the CALLS proposal resolved many outstanding issues
before the FCC including: the court remand of the 6.5% productivity factor; the
treatment of implicit universal service support; the treatment of low-volume
long-distance users; and the next scheduled price cap review. The CALLS plan has
a five year life and provides for the following: elimination of the residential
presubscribed interexchange carrier charge; increases in subscriber line
charges; reductions in switched access usage rates; the removal of certain
implicit universal service support from access charges and direct recovery from
end users; and commitments from participating IXCs to pass through access charge
reductions to end users. We have opted into the five-year CALLS plan.

     Advanced Telecommunications Services.  On two separate occasions the FCC
has ruled that advanced services provided by an ILEC are covered by those
provisions of the Act that govern telephone exchange and exchange access
services. We have challenged this finding, contending that advanced services fit
within neither category and are not properly treated as exchange services. On
April 20, 2001, the Court of Appeals vacated and remanded to the FCC its
classification of DS2-based advanced services.

     InterLATA Long-Distance Entry.  Several Regional Bell Operating Companies
("RBOCs") have filed for entry into the interLATA long-distance business.
Although many of these applications have been supported by state PUCs, the FCC
had rejected all applications until December 1999. As of September 30, 2001,
long-distance authority has been granted in the states of Connecticut, Kansas,
Massachusetts, New York, Oklahoma, Pennsylvania and Texas.

     We filed applications with all of our local service area state PUCs for
support of our planned applications to the FCC for authority to enter the
interLATA long-distance business. Workshops and related proceedings are underway
at the state level to evaluate our satisfaction of requirements under the Act
that must be met in order for an RBOC to obtain long-distance authority. We have
agreed to test operational support systems on a regional basis in thirteen
states, and testing of those systems began in March 2001. Testing in Arizona is
being conducted separately, and began in February 2001. We are on track to
receive FCC approval to provide long-distance service in each of our 14 states
by mid-2002.

     Reciprocal Compensation for Internet Service Providers ("ISPs").  On April
27, 2001, the FCC issued an Order with regard to Intercarrier Compensation for
ISP bound traffic. The Order required carriers serving ISP bound traffic to
reduce reciprocal compensation rates over a 36 month period beginning with an
initial reduction to $0.0015 per minute of use and ending with a rate of $0.0007
per minute of use. In addition, a cap was placed on the number of minutes of use
on which the terminating carrier may charge such rates. This reduction will
lower costs that we pay CLECs for delivering such traffic to other carriers.

NEW ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement establishes
accounting and reporting standards for derivative instruments and hedging
activities. SFAS No. 133 requires, among other things, that all derivative
instruments be recognized at fair value as assets or liabilities in the
consolidated balance sheets and changes in fair value generally be recognized
currently in earnings unless specific hedge accounting criteria are met. The
adoption of SFAS No. 133 on January 1, 2001 did not have a material impact on
our consolidated financial results.

     In September 2000, the FASB issued SFAS No. 140, "Accounting for Transfers
and Servicing of Financial Assets and Extinguishments of Liabilities." This
statement provides accounting and reporting standards for transfers and
servicing of financial assets and extinguishment of liabilities. SFAS No. 140
requires that after a transfer of financial assets, an entity continues to
recognize the financial and servicing assets it controls and the liabilities it
has incurred and does not recognize those financial and servicing assets

                                        14

when control has been surrendered and the liability has been extinguished. SFAS
No. 140 is effective for transfers and servicing of financial assets and
extinguishments of liabilities occurring after March 31, 2001. Adoption of SFAS
No. 140 did not have a material impact on our consolidated financial results.

     In June 2001, the FASB issued SFAS No. 141, "Business Combinations." This
pronouncement eliminated the use of the "pooling of interests" method of
accounting for all mergers and acquisitions. As a result, all mergers and
acquisitions will be accounted for using the "purchase" method of accounting.
SFAS No. 141 is effective for all mergers and acquisitions initiated after June
30, 2001. Adoption of this pronouncement has no impact on our results from
operations or our financial position.

     In June 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible
Assets." This statement addresses financial accounting and reporting for
intangible assets (excluding goodwill) acquired individually or with a group of
other assets at the time of their acquisition. It also addresses financial
accounting and reporting for goodwill and other intangible assets subsequent to
their acquisition. Intangible assets (excluding goodwill) acquired outside of a
business combination will be initially recorded at their estimated fair value.
If the intangible asset has a finite useful life, it will be amortized over that
life. Intangible assets with an indefinite life are not amortized. Both types of
intangible assets will be reviewed annually for impairment and a loss recorded
when the asset's carrying amount exceeds its estimated fair value. Goodwill will
be treated similar to an intangible asset with an indefinite life. SFAS No. 142
is effective for fiscal years beginning after December 15, 2001. The adoption of
SFAS No. 142 will have no impact on our consolidated financial results.

     In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations." This statement deals with the costs of closing
facilities and removing assets. SFAS No. 143 requires entities to record the
fair value of a legal liability for an asset retirement obligation in the period
it is incurred. This cost is initially capitalized and amortized over the
remaining life of the underlying asset. Once the obligation is ultimately
settled, any difference between the final cost and the recorded liability is
recognized as a gain or loss on disposition. SFAS No. 143 is effective for years
beginning after June 15, 2002. We are currently evaluating the impact this
pronouncement will have on our future consolidated financial results.

     In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets." This pronouncement addresses how
to account for and report impairments or disposals of long-lived assets. Under
SFAS No. 144, an impairment loss is to be recorded on long-lived assets being
held or used when the carrying amount of the asset is not recoverable from its
undiscounted cash flows. The impairment loss is equal to the difference between
the asset's carrying amount and estimated fair value. Long-lived assets to be
disposed of by other than a sale for cash are to be accounted for and reported
like assets being held or used except the impairment loss is recognized at the
time of the disposition. Long-lived assets to be disposed of by sale are to be
recorded at the lower of their carrying amount or estimated fair value (less
costs to sell) at the time the plan of disposition has been approved and
committed to by the appropriate company management. In addition, depreciation is
to cease at the same time. SFAS No. 144 is effective for fiscal years beginning
after December 15, 2001. We are currently evaluating the impact this
pronouncement will have on our future consolidated financial results.
