                              7.50% NOTES DUE 2008
                                       FOR
                          7.50% SERIES B NOTES DUE 2008
                                       OF
                     QWEST COMMUNICATIONS INTERNATIONAL INC.

   
We are offering,  on the terms and conditions  described in this prospectus,  to
exchange all of our  outstanding  7.50% Senior Notes due 2008 for our registered
7.50%  Series B Senior  Notes due 2008.  We issued the notes on November 4, 1998
and a total principal amount of $750.0 million is outstanding.  The terms of the
new 7.50% notes are  identical  to the terms of the old 7.50% notes  except that
the new 7.50% notes are registered  under federal  securities  laws and will not
contain any legends restricting their transfer.


                       Information about the 7.50% Notes:
                -----------------------------------------------
* Please consider the following:

- -    The 7.50% notes will mature on November 1, 2008.


- -    We will pay interest on the 7.50% notes semi-annually on May 1 and November
     1 of each year beginning May 1, 1999, at the rate of 7.50% per year.

- -    We have the  option to redeem  all or a portion  of the 7.50%  notes at any
     time at the redemption price set forth on page __ of this prospectus.

- -    You should carefully  review the Risk Factors  beginning on page __ of this
     prospectus.

- -    Our offer to  exchange  old 7.50%  notes for new 7.50%  notes  will be open
     until 5:00 p.m.,  New York City time,  on  _____________,  1999,  unless we
     extend the offer.

- -    You should also carefully review the procedures for tendering the old 7.50%
     notes beginning on page __ of this prospectus.

- -    The 7.50% notes are senior unsecured obligations and rank equal in right of
     payment to our existing  future  senior debt and senior in right of payment
     to our existing and future  subordinated debt. As of September 30, 1998, we
     had $1,301.2  million of senior debt  ranking  equal in right of payment to
     the 7.50% notes.

- -    If you fail to  tender  your old 7.50%  notes,  you will  continue  to hold
     unregistered  securities  and  your  ability  to  transfer  them  could  be
     adversely affected.


- -    No public market currently exists for the 7.50% notes.

     We do not  intend to list the new 7.50%  notes on any  securities  exchange
and, therefore, no active public market is anticipated.

Commission has approved or  disapproved  of these  securities or passed upon the

                               PROSPECTUS SUMMARY

   
This brief summary highlights selected information from the prospectus.  It does
not  contain all of the  information  that is  important  to you. We urge you to
carefully read and review the entire prospectus and the other documents to which
it refers to fully  understand the terms of the new 7.50% notes and the exchange
offer. We sometimes  refer to Qwest  Communications  International  Inc. in this
prospectus  as "Qwest" and,  together  with its  subsidiaries,  including  Qwest
Communications Corporation ("QCC"), as the "Company."
    

THE COMPANY
   
We offer a full range of  multimedia  communications  services  through two core
businesses: Communications Services and Construction Services.

Communications Services includes Retail Services and Wholesale Services.  Retail
Services  provides voice,  data, video and related services to both business and
residential customers.  Wholesale Services provides high-volume and conventional
private line services to other communications  providers, as well as to Internet
service  providers and other data service  companies.  We are  developing  these
services in partnership with leading information technology companies, including
Microsoft (business applications and services) and Netscape (one-stop access for
various communications services accessed over the Internet).

Construction  Services  constructs  and installs  fiber optic  systems for other
communications providers, as well as for our own use.

Our Macro  Capacity  (SM) Fiber  Network,  an  approximately  18,450  route-mile
coast-to-coast  fiber-optic communications system, is central to our strategies.
The technologically advanced network uses a self-healing SONET ring architecture
that  prevents  interruption  of service  to our  customers  by  instantaneously
rerouting  traffic in the event of a fiber cut. The network is equipped with the
most advanced commercially available fiber, manufactured by Lucent Technologies,
and  the  most  advanced  transmission  electronics,  manufactured  by  Northern
Telecom.  At full  capacity,  our network will  transmit  two  trillion  bits of
multimedia information per second. Our state-of-the-art Internet Protocol ("IP")
architecture supports ATM (asynchronous transfer mode)and Frame Relay services ,
as well as circuit switched services.

In April,  1998,  we became the first  network  service  provider  to complete a
transcontinental IP fiber network when we activated our network from Los Angeles
to San  Francisco  to New York.  We expect our network to be fully  activated in
1999.

                                                          4

<PAGE>

In addition to significant  advantages in service speed and sophistication,  our
network's advanced  technologies should also provide a cost advantage over older
fiber systems  generally in commercial use today.  We expect an additional  cost
benefit  from the sale of dark fiber  along the  network,  which will reduce the
cost per fiber mile we retain for our own use.

Under our  current  plan,  the  network  will  serve more than 130 cities and 80
percent of the data and voice traffic  originating in the United States.  Leased
digital fiber optic  facilities and more than 15 switches  throughout the United
States connect our network to  metropolitan  areas that account for more than 95
percent of U.S. call volume.

We are also moving aggressively to expand the network beyond the U.S. We plan to
complete an  extension  of the U.S.  network  into Mexico in early 1999.  We own
capacity on three undersea systems linking the network to Europe and are part of
a consortium of companies  building a submarine cable system connecting the U.S.
to Japan, a project scheduled for completion in the year 2000.

We believe that the  technological  advantages  and growing reach of our network
will put us in an  excellent  position  to  capture  market  share and take full
advantage of the rapidly growing demand for voice and data transmission capacity
and services.

RECENT DEVELOPMENTS

Credit Facility  Commitment.  On November 5, 1998, we signed a commitment letter
with our three lead banks to syndicate an unsecured  credit  facility of between
$500  million and $750  million.  Each of the lead banks  agreed to commit up to
$100.0 million,  with a minimum  aggregate  commitment of $250.0 million.  After
this,  the Company  sold $300.0  million of 7.25% Senior Notes due 2008 and sold
$200.0  million of common stock to Microsoft  Corporation.  As a result of these
transactions,  the  Company  postponed  closing of the credit  facility.  We are
currently in the process of  obtaining a new  unsecured  $750.0  million to $1.0
billion credit facility through a syndicate of banks.  Closing of the new credit
facility is conditioned,  among other things, on a mutually  satisfactory credit
agreement.  The Company and the syndicate of banks are working toward closing in
the first quarter of 1999. 5

<PAGE>


Issuances of Notes.  On November 27, 1998, we issued and sold $300.0  million in
principal  amount of our 7.25% Senior Notes due 2008.  The net proceeds from the
offering was  approximately  $297.5  million,  after  deducting  offering costs.
Interest on the 7.25% Notes Due 2008 is payable semiannually in arrears on May 1
and November 1 of each year,  commencing  May 1, 1999.  The 7.25% Notes Due 2008
are subject to  redemption  at our option,  in whole or in part,  at any time at
specified redemption prices.

In  connection  with the sale of the 7.25% Notes Due 2008,  we agreed to make an
offer to exchange new notes,  registered  under the  Securities  Act of 1933 and
with terms  identical in all material  respects to the original  notes,  for the
original notes or, alternatively,  to file a shelf registration  statement under
the Securities Act with respect to the original notes.

Redemption of Notes.  On December 31, 1998, we redeemed  $87.5 million of our 10
7/8% Senior Notes Due 2007.  Bankers Trust Company,  the Trustee for the 10 7/8%
notes,  issued the required notice to affected  noteholders on December 1, 1998.
Under the terms of the Indenture  for the 10 7/8% notes,  dated August 28, 1997,
we may redeem up to 35%, or $87.5 million,  of the $250 million principal amount
of the 10 7/8% notes.

Equipment Credit Facility.  In December 1998, we repaid the outstanding  balance
of our equipment credit facility.  The balance of the facility was $57.3 million
at September 30, 1998.

Our principal  executive offices are located at 700 Qwest Tower, 555 Seventeenth
Street, Denver, Colorado 80202, and our telephone number is (303) 992-1400.

The Exchange Offer

Securities to be Exchanged...               

     On November 4, 1998, we issued $750.0 million aggregate principal amount of
     old 7.50% notes to the initial  purchaser in a transaction  exempt from the
     registration requirements of the Securities Act. The terms of the new 7.50%
     notes and the old 7.50% notes are  substantially  identical in all material
     respects,  except that the new 7.50% notes will be freely  transferable  by
     the  holders  except  as  otherwise   provided  in  this  prospectus.   See
     "Description of the 7.50% Notes."

The Exchange Offer...........               

     $1,000  principal  amount of new 7.50%  notes in  exchange  for each $1,000
     principal amount of old 7.50% notes. As of the date of this prospectus, old
     7.50% notes  representing  $750.0 million  aggregate  principal  amount are
     outstanding.

     Based on  interpretations  by the staff of the Commission,  as set forth in
     no-action  letters  issued to certain  third  parties  unrelated  to us, we
     believe  that new 7.50%  notes  issued  pursuant to the  exchange  offer in
     exchange for old 7.50% notes may be offered for resale, resold or otherwise
     transferred  by holders  (other than any holder which is an  "affiliate" of
     the Company within the meaning of Rule 405 promulgated under the Securities
     Act, or a  broker-dealer  who purchased old 7.50% notes directly from us to
     resell pursuant to Rule 144A or any other available  exemption  promulgated
     under the Securities  Act),  without  compliance with the  registration and
     prospectus  delivery  requirements of the Securities Act, provided that the
     new 7.50%  notes  are  acquired  in the  ordinary  course  of the  holders'
     business and the holders have no arrangement with any person to engage in a
     distribution of new 7.50% notes.

     However,  the  Commission  has not  considered  the  exchange  offer in the
     context of a  no-action  letter and we cannot be sure that the staff of the
     Commission would make a similar determination with respect to this exchange
     offer.  Furthermore,   each  holder,  other  than  a  broker-dealer,   must
     acknowledge  that it is not engaged in, and does not intend to engage in, a
     distribution of the new 7.50% notes and has no arrangement or understanding
     to  participate in a distribution  of new 7.50% notes.  Each  broker-dealer
     that receives new 7.50% notes for its own account  pursuant to the exchange
     offer must  acknowledge  that it will comply with the  prospectus  delivery
     requirements of the Securities Act in connection with any resale of the new
     7.50% notes.  Broker-dealers  who acquired old 7.50% notes directly from us
     and not as a result of market-making activities or other trading activities
     may not rely on the staff's interpretations  discussed above or participate
     in the  exchange  offer  and  must  comply  with  the  prospectus  delivery
     requirements of the Securities Act in order to resell the old 7.50% notes.

Registration Rights
  Agreement..................               

     We sold the old 7.50%  notes on November  4, 1998,  in a private  placement
     relying on Section 4(2) of

                                                          7

<PAGE>



     the  Securities  Act.  The old 7.50% notes were  immediately  resold by the
     initial  purchaser  in reliance on Rule 144A under the  Securities  Act. In
     connection with the sale, we entered into a Registration  Rights  Agreement
     with the initial  purchaser  requiring us to make the exchange  offer.  The
     Registration Rights Agreement also provides that we must use our reasonable
     best efforts to (i) cause the registration statement for the exchange offer
     to be declared effective within 150 days of the date on which we issued the
     old 7.50%  notes and (ii) close the  exchange  offer on or before the 180th
     day  following  the date on which we issued the old 7.50%  notes.  See "The
     Exchange Offer -- Purpose and Effect."

Expiration Date..............               

     The  exchange  offer  will  expire  at  5:00  p.m.,  New  York  City  time,
     ____________, 1999 or a later date and time to which we extend it.

Withdrawal...................               

     The tender of the old 7.50%  notes  pursuant to the  exchange  offer may be
     withdrawn at any time prior to 5:00 p.m., New York City time, on , 1999, or
     a later date and time to which we extend the offer. Any old 7.50% notes not
     accepted for exchange  for any reason will be returned  without  expense to
     the  tendering  holder  as soon as  practicable  after the  exchange  offer
     expires or terminates.

Interest on the New 7.50% Notes and
  the Old 7.50% Notes..............               

     Interest on the new 7.50%  notes will accrue from the date of the  original
     issuance  of the old  7.50%  notes or from  the  date of the last  periodic
     payment  of  interest  on the old  7.50%  notes,  whichever  is  later.  No
     additional  interest will be paid on old 7.50% notes  tendered and accepted
     for exchange.

Conditions to the Exchange 
  Offer......................               

     The exchange offer is subject to certain customary  conditions,  certain of
     which may we may waive.  See "The Exchange  Offer -- Certain  Conditions to
     Exchange Offer."

Procedures for Tendering Old 7.50% 
  Notes......................               

     Each holder of the old 7.50%  notes  wishing to accept the  exchange  offer
     must  complete,  sign and date the  letter of  transmittal,  or a copy,  in
     accordance  with the  instructions  contained in this prospectus and in the
     letter of transmittal, and

     mail or otherwise deliver the letter of transmittal,  or the copy, together
     with the old  7.50%  notes  and any other  required  documentation,  to the
     exchange agent at the address set forth in this prospectus. Persons holding
     the old 7.50%  notes  through  the  Depository  Trust  Company  ("DTC") and
     wishing  to accept the  exchange  offer  must do so  pursuant  to the DTC's
     Automated  Tender Offer Program,  by which each tendering  participant will
     agree to be bound by the letter of transmittal. By executing or agreeing to
     be bound by the letter of  transmittal,  each holder will  represent  to us
     that, among other things,  (i) the new 7.50% notes acquired pursuant to the
     exchange offer are being obtained in the ordinary course of business of the
     person  receiving  the new 7.50%  notes,  whether  or not the person is the
     registered  holder of the old 7.50% notes,  (ii) the holder is not engaging
     in and does not intend to engage in a distribution  of the new 7.50% notes,
     (iii) the holder does not have an  arrangement  or  understanding  with any
     person to participate in the  distribution of the new 7.50% notes, and (iv)
     the holder is not an  "affiliate,"  as defined  under Rule 405  promulgated
     under the Securities Act, of our company.

     We will accept for  exchange any and all old 7.50% notes which are properly
     tendered (and not  withdrawn) in the exchange offer prior to 5:00 p.m., New
     York City time,  on , 1999.  The new 7.50%  notes  issued  pursuant  to the
     exchange offer will be delivered  promptly  following the expiration  date.
     See "The Exchange Offer -- Terms of the Exchange Offer."

Exchange Agent...............               

     The Bank of New York is serving as exchange  agent in  connection  with the
     exchange offer.

Federal Income Tax
  Considerations.............               

     In the  opinion of our  counsel,  the  exchange  of old 7.50% notes for new
     7.50% notes in the  exchange  offer  should not be a taxable  exchange  for
     United  States  federal  income tax  purposes.  See "Certain  United States
     Federal Income Tax Considerations."

Effect of not Tendering......               

     Old 7.50% notes that are not tendered or that are tendered but not accepted
     will,  following  the  completion  of the  exchange  offer,  continue to be
     subject to the existing restrictions upon transfer. We will have no further
     obligation to provide for the registration  under the Securities Act of the
     old 7.50% notes.

The New 7.50% Notes

     The summary below  describes  the  principal  terms of the new 7.50% notes.
     Certain  of the  terms  and  conditions  described  below  are  subject  to
     important limitations and exceptions.  The "Description of the 7.50% Notes"
     section of this  prospectus  beginning on page 47 contains a more  detailed
     description of the terms and conditions of the new 7.50% notes.

Issuer.......................               

     Qwest Communications International Inc.

Securities Offered...........               

     $750,000,000 principal amount of 7.50% Series B Senior Notes Due 2008

Maturity.....................               

     November 1, 2008

Interest Rate................              

     7.50% per year (calculated using a 360-day year)

Ranking......................               

     The new 7.50% notes will be senior unsecured  obligations of Qwest and will
     rank equal in right of payment to our existing  and future  senior debt and
     senior  in  right  of  payment  to  all  of  Qwest's  existing  and  future
     subordinated  debt.  The new 7.50%  notes are not secured by any assets and
     are  effectively  subordinated  to our future secured  indebtedness  to the
     extent  of the  value  of  the  assets  securing  the  indebtedness.  As of
     September  30,  1998,  on a pro  forma  basis  after  giving  effect to the
     acquisition  of Icon CMT Corp.,  the  redemption of $87.5 million of our 10
     7/8%  notes,  the  repayment  of  $57.3  million  of our  equipment  credit
     facility,  the offering of the old 7.50%  notes,  the offering of our 7.25%
     Senior  Notes Due 2008 and the use of the  proceeds  from these  offerings,
     Qwest  would  have  had  approximately  $1,912.0  million  of  indebtedness
     outstanding, none of which was secured. The new 7.50% notes are effectively
     subordinated  to all of the  present  and  future  indebtedness  and  other
     liabilities  of our  subsidiaries  (including  trade  payables).  The total
     liabilities  of our  subsidiaries  (after  the  elimination  of  loans  and
     advances by us to our subsidiaries) would have been approximately  $1,893.7
     million, of which approximately $32.0 million was secured. Any rights of us
     and our creditors, including the holders of new 7.50% notes, to participate
     in  the  assets  of  any  of  our  subsidiaries  upon  any  liquidation  or
     reorganization of any the subsidiary will be

                                                          10

<PAGE>



     subject to the prior claims of that subsidiary's creditors (including trade
     creditors).

Optional Redemption..........               

     We can  redeem  the  7.50%  notes  at any  time at a  price  of 100% of the
     principal amount plus the Applicable Premium (as defined).

Change of Control Offer......               

     If a "Change of Control" of our Ccmpany occurs (as defined in the indenture
     for  the  7.50%  notes),  we  must  give  holders  of the  7.50%  notes  an
     opportunity to sell us their 7.50% notes at 101% of their face amount, plus
     accrued interest.

     We might not be able to pay you the required  price for new 7.50% notes you
     request us to  purchase  at the time of a Change of Control  because we may
     also have to repay our senior credit facility and may not have enough funds
     to repay all of our senior debt at that time.

Asset Sale Proceeds..........               

          If we  engage  in  certain  asset  sales,  we must  generally  use the
          proceeds (1) first,  to the repayment of debt then  outstanding  under
          any credit facility,  to the extent the agreements would require us to
          do so or prohibit note  repurchases;  (2) second, to offer to purchase
          outstanding  7.50% notes at 100% of their face  amount,  plus  accrued
          interest;  (3) third,  to the repayment of other debt; and (4) fourth,
          to any other company use.

Certain Indenture
Provisions...................               

     The indenture  governing the 7.50% notes  contains  covenants  limiting our
     (and most of our subsidiaries') ability to:

     - borrow additional money,

     - pay dividends or other distributions to stockholders,

     - allow subsidiaries to guarantee our debt,

     - limit the ability of subsidiaries to make payments to us,

     - make certain investments,

     - create certain liens on our assets,

     - sell certain assets,

     - enter into transactions with affiliates,  and - engage in certain mergers
     or consolidations.

     These  covenants  are  subject  to a number of  important  limitations  and
     exceptions and are more fully  described  under  "Description  of the 7.50%
     Notes" beginning on page 47.

                                                          11

<PAGE>



     Under the terms of the indenture for the 7.50% notes, we have no obligation
     to comply with most of the covenants during any period when the 7.50% notes
     have been assigned  investment grade ratings. If the 7.50% notes later lose
     an investment  grade rating,  the covenants  will again apply,  but actions
     taken during the period  generally  cannot cause us to be in default if the
     covenants again become effective.  Consequently, the protection afforded by
     the covenants could be weakened if the 7.50% notes are assigned  investment
     grade ratings and subsequently downgraded to non-investment grade.

Use of Proceeds..............               

     We will not receive any cash  proceeds  from the  issuance of the new 7.50%
     notes pursuant to this prospectus.


RISK FACTORS

We urge you to  carefully  review the Risk  Factors  beginning  on page 25 for a
discussion of factors you should consider before exchanging your old 7.50% notes
for new 7.50% notes.

                SELECTED HISTORICAL AND UNAUDITED PRO FORMA
                       CONDENSED COMBINED FINANCIAL DATA

The selected unaudited pro forma condensed combined statement of operations data
for the year ended December 31, 1997 and for the nine months ended September 30,
1998 gives effect to the acquisitions of SuperNet,  Inc., Phoenix Network, Inc.,
LCI  International,  Inc. and subsidiary ("LCI") and Icon as if the acquisitions
had occurred on January 1, 1997.  The  unaudited  pro forma  condensed  combined
balance  sheet data as of September 30, 1998 set forth below gives effect to the
proposed  acquisition by us of all the issued and outstanding  shares of capital
stock of Icon and the  assumption  of the Icon stock  options and warrants as if
the acquisition  had occurred on September 30, 1998. The selected  unaudited pro
forma condensed  combined financial data does not give effect to our acquisition
of EUnet  International Ltd. and the joint venture with KPN Telecom B.V. because
the  disclosure  is not  required  under Rule 3-05 of  Securities  and  Exchange
Commission Regulation S-X.

The selected  unaudited pro forma condensed  combined financial data give effect
to the acquisitions  described above under the purchase method of accounting and
are  based on the  assumptions  and  adjustments  described  in the notes to the
Unaudited Pro Forma  Condensed  Combined  Financial  Statements  incorporated by
reference  in this  prospectus.  The  fair  value of the  consideration  will be
allocated to the assets and  liabilities  acquired based upon the fair values of
the assets and liabilities at the date of each respective acquisition and may be
revised  for a  period  of up to one  year  from  the  date of  each  respective
acquisition.  The  preliminary  estimates and assumptions as to the value of the
assets and  liabilities  of LCI and Icon to the combined  company are based upon
information  available at the date of  preparation  of the  Unaudited  Pro Forma
Condensed  Combined  Financial  Statements,  and will be adjusted upon the final
determination of the fair values.  The items awaiting final  allocation  include
LCI network asset valuation and final  determination  of the costs to sell these
assets.  It is anticipated  that final allocation of the LCI purchase price will
not differ materially from the preliminary allocation.

We have  undertaken a study to determine  the  allocation  of the Icon  purchase
price  to  the  various  assets  acquired,  including  in-process  research  and
development projects,  and the liabilities assumed. Based on our's consideration
of the study's preliminary findings as of this date, we have allocated a portion
of purchase price to certain  intangible assets,  including  in-process R&D. See
the  footnotes to the pro forma  condensed  combined  financial  statements  for
further information on the preliminary allocation of purchase price.

The  selected  historical  financial  data as of the end of, and for each of the
years in, the five year period ended  December 31, 1997 and as of September  30,
1998 and 1997 and for the nine  months  ended  September  30, 1998 and 1997 have
been taken or derived  from the  respective  historical  consolidated  financial
statements of Qwest.

(1)  On June 5, 1998,  we acquired LCI. The  acquisition  was accounted for as a
     purchase and the results of LCI's operations are included with ours for the
     period subsequent to the acquisition.

(2)  In November  1993,  we sold  substantially  all of the fiber optic  network
     capacity  and  related  equipment  and  assets  that  we  owned  then  to a
     third-party  purchaser  for $185.0  million.  After  deducting the carrying
     value of the assets  sold and direct  costs  associated  with the sale,  we
     recognized a gain of approximately $126.5 million.

(3)  EBITDA  represents  net earnings  (loss)  before  interest,  income  taxes,
     depreciation and  amortization,  a nonrecurring  expense of $2.6 million in
     the year ended  December 30, 1996 to  restructure  operations,  the gain on
     sale  of   telecommunications   agreements   of  $6.1  million   (which  is
     non-recurring)  in the year ended  December 31,  1996,  the gain on sale of
     contract rights of approximately  $9.3 million (which is  non-recurring) in
     the year ended December 31, 1997 and non-recurring expenses of $813 million
     in the nine months  ended  September  30,  1998  related to the LCI merger.
     EBITDA includes  earnings from the  construction  contracts for the sale of
     dark fiber that we will use to provide  cash for the  construction  cost of
     our network.  EBITDA does not represent cash flow for the periods presented
     and should not be considered as an alternative to net earnings (loss) as an
     indicator of our operating  performance  or as an alternative to cash flows
     as a source of liquidity,

     and may not be comparable with EBITDA as defined by other companies.  Qwest
     believes that EBITDA is commonly  used by financial  analysts and others in
     the telecommunications industry. Without the effect of Qwest's growth share
     plan expense,  EBITDA would have been $115.2  million,  $20.0 million,  and
     $1.8  million  for the  years  ended  December  31,  1997,  1996 and  1993,
     respectively,  and $153.4  million  and $80.6  million  for the nine months
     ended September 30, 1998 and 1997, respectively.

(4)  Capital  expenditures  include  expenditures  for property  and  equipment,
     accrued  capital  expenditures,  capital  expenditures  financed  with  the
     equipment credit facility and initial obligations under capital leases.

(5)  Earnings were  insufficient  to cover fixed  charges by $864.0  million and
     $6.7 million for the nine month periods ended  September 30, 1998 and 1997,
     respectively,  and $12.6  million,  $40.4 million and $11.0 million for the
     years ended December 31, 1996, 1995 and 1994.

(6)  We have not  declared  or paid cash  dividends  on our common  stock  since
     becoming a public company in June 1997.

                         CAUTIONARY STATEMENT REGARDING
                           FORWARD-LOOKING STATEMENTS

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

(i)  statements  concerning  the  benefits  that we expect  will result from our
business  activities  and  certain  transactions  we  have  completed,  such  as
synergies  in the form of  increased  revenues,  decreased  expenses and avoided
expenses and expenditures,

(ii) our plans to complete our communications network and

(iii)  other  statements  of  our  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 we have filed with the Commission.  You can find
many of these  statements  by looking for words such as  "believes,"  "expects,"
"anticipates,"  "estimates," or similar  expressions  used in this prospectus or
incorporated by reference in this prospectus.

These forward-looking statements are subject to numerous assumptions,  risks and
uncertainties that may cause our actual results,  performance or achievements to
be materially  different from any future  results,  performance or  achievements
expressed  or implied  by us in those  statements.  The risks and  uncertainties
include  those risks,  uncertainties  and risk factors  identified,  among other
places, under "Risk Factors" in this prospectus, beginning on page 25, and under
"Risk Factors" and "Management's  Discussion and Analysis of Financial Condition
and Results of  Operations" in the documents  incorporated  by reference in this
prospectus.

The most important factors that could prevent us from achieving our stated goals
include, but are not limited to, the following:

- - our failure  to construct our communications network on schedule and on
budget;

- - operating and financial  risks related to managing  rapid growth,  integrating
acquired businesses and sustaining  operating cash flow to meet our debt service
requirements, make capital expenditures and fund operations;

- - potential fluctuation in quarterly results;

- - volatility of stock price;

- - intense competition in the communications services market;

- - dependence on new product development;

- - our ability to achieve year 2000 compliance;

- - rapid and significant changes in technology and markets;

- - adverse changes in the regulatory or legislative environment affecting our
business;

- - failure to maintain necessary rights of way; and

- - satisfactory negotiation and execution of certain definitive documentation.

Because the  statements are subject to risks and  uncertainties,  actual results
may differ  materially  from those  expressed or implied by the  forward-looking
statements.  You are  cautioned not to place undue  reliance on the  statements,
which speak only as of the date of this  prospectus 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 we or persons  acting on our behalf may issue.  We undertake 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  prospectus  or to reflect  the
occurrence of unanticipated events.

                                 RISK FACTORS

In addition to the other  information  in this  prospectus,  the following  risk
factors should be considered  carefully in evaluating us and our business before
participating in the exchange offer.

Effect of Not Tendering

Holders of old 7.50%  notes who do not  exchange  their old 7.50%  notes for new
7.50% notes will continue to be subject to the  restrictions  on transfer of the
old 7.50% notes as set forth in the legends on the old 7.50% notes.  In general,
the old 7.50% notes may not be offered or sold, unless they are registered under
the  Securities  Act  or  are  exempt  from  registration.   See  "The  Exchange
Offer--Consequences of Failure to Exchange."

Holding Company Structure; Subordination of the 7.50% Notes to Indebtedness of
Subsidiaries

The 7.50% notes are obligations  only of Qwest,  which is a holding company with
no material assets other than the stock of its  subsidiaries.  Our  subsidiaries
conduct  substantially  all of our operations and own  substantially  all of our
assets.  As a result,  our cash flow and our  ability  to meet our debt  service
obligations,  including payments on the 7.50% notes, depends on the cash flow of
our  subsidiaries  and the  payment of funds by them to us in the form of loans,
dividends or  otherwise.  Our  subsidiaries  generally are not obligated to make
funds  available  to us for  payment on the 7.50%  notes or for other  purposes.
Existing debt agreements of our subsidiaries impose, and future debt instruments
of our subsidiaries may impose,  significant  restrictions on the ability of our
subsidiaries to pay dividends or make other  distributions or loans and advances
to us. In addition,  the ability of our  subsidiaries to make any payments to us
will  depend  on their  earnings,  business  and tax  considerations  and  legal
restrictions.

As a result,  the 7.50% notes  effectively  will rank junior to all existing and
future  indebtedness,  trade payables and other liabilities of our subsidiaries.
In the event of a bankruptcy or dissolution of a subsidiary,  our rights and the
rights of our creditors,  including the holders of the 7.50% notes,  to share in
the  assets  of the  subsidiary  will be  subject  to the  prior  claims  of the
subsidiary's creditors.  After the payment of the subsidiary's liabilities,  the
subsidiary may not have enough assets remaining to pay us and our creditors.  On
a pro forma basis after giving effect to the acquisition of Icon, the redemption
of $87.5  million of our 10 7/8% notes,  the  repayment of $57.3  million of our
equipment  credit  facility,  the  offering  of our 7.25%  Notes  Due 2008,  the
offering  of the  old  7.50%  notes  and  the  use of the  proceeds  from  these
offerings,  at September 30, 1998, our subsidiaries would have had approximately
$1,893.7  million of outstanding  liabilities.  All of these  liabilities  would
effectively rank senior to the 7.50% notes. We expect that our subsidiaries will
incur additional indebtedness in the future.


                                                          20

<PAGE>



The 7.50% Notes are Unsecured; Subordination of the 7.50% Notes to Secured
Indebtedness

The 7.50% notes will be general unsecured obligations of Qwest. As a result, the
7.50%  notes  will rank  junior in right of  payment to the claims of all of our
secured creditors to the extent of the value of the secured assets. If a default
or  acceleration  of our debt  occurs,  the  holders of the debt could seize the
assets securing the debt and sell the assets to satisfy all or a part of what is
owed. On a pro forma basis,  after giving effect to the acquisition of Icon, the
redemption of $87.5 million of our 10 7/8% notes, the repayment of $57.3 million
of our  equipment  credit  facility,  the offering of the old 7.50%  notes,  the
offering  of our 7.25%  Notes Due 2008 and the use of the  proceeds  from  these
offerings,  at September 30, 1998, we would have had approximately $32.0 million
of secured indebtedness. Future indebtedness incurred by us also may be secured.

The value of a substantial portion of our fixed assets is derived from employing
the assets in a communications business. These assets are highly specialized and
we expect  that,  taken  individually,  they would have  limited  marketability.
Consequently,  in the event of a realization by secured  creditors on the assets
of our subsidiaries, creditors would likely seek to sell the business as a going
concern in order to maximize the proceeds  realized.  The price  obtained upon a
sale could be adversely affected by the necessity to obtain approval of the sale
from the applicable regulatory  authorities and compliance with other applicable
governmental regulations.

Substantial Indebtedness; Ability to Incur Additional Debt

We have a significant amount of debt outstanding. As of September 30, 1998, on a
pro forma basis,  after giving effect to the acquisition of Icon, the redemption
of $87.5  million of our 10 7/8% notes,  the  repayment of $57.3  million of our
equipment credit facility,  the offering of the old 7.50% notes, the offering of
our 7.25% Notes Due 2008 and the use of proceeds from these offerings,  we would
have had approximately $2,295.7 million of long-term debt (including the current
portion),  and a  debt-to-equity  ratio of 0.6 to 1.0.  You should be aware that
this  significant  amount of debt could have important  consequences to you as a
holder of the 7.50% notes. For example,  a significant  portion of our cash flow
from operations must be dedicated to the repayment of the indebtedness,  thereby
reducing the amount of cash we have available for other purposes.

The indenture  governing the 7.50% notes limits,  but does not prohibit,  us and
our  subsidiaries  from  incurring  additional  debt.  We expect that we and our
subsidiaries may incur substantial additional debt in the future. On November 5,
1998,  we signed a  commitment  letter with our three lead banks to syndicate an
unsecured  credit  facility of between $500 million and $750  million.  The lead
banks  agreed to a minimum  aggregate  commitment  of  $250.0  million  with the
remainder  expected to be provided by other banks to be added to the  syndicate.
After this,  the Company sold $300.0  million of 7.25% Senior Notes due 2008 and
sold $200.0  million of common  stock to Microsoft  Corporation.  As a result of
these  transactions,  the Company postponed closing of the credit facility.  The
Company is currently in the process of obtaining a new unsecured  $750.0 million
to $1.0 billion credit facility through a syndicate of banks. Closing of the new
credit facility is conditioned,  among other things, on a mutually  satisfactory
credit  agreement.  The Company and the  syndicate  of banks are working  toward
closing in the first quarter of 1999. 21

Our ability to pay the  principal  of and  interest on our debt will depend upon
our future performance, which is subject to several uncertainties, many of which
are beyond our control.  We cannot assure you that we will have enough cash flow
in  the  future  to  let us  meet  our  anticipated  debt  service  requirements
(including  those  with  respect  to the 7.50%  notes).  Although  we  currently
anticipate  that we will pay the  principal and interest on the 7.50% notes with
cash flow from  operations,  we cannot  assure  you in this  regard.  Failure to
generate sufficient cash flow may impair our ability to obtain additional equity
or debt  financing  or to meet  our debt  service  requirements,  including  the
payment of principal and interest on the 7.50% notes. In those circumstances, we
may be required to  renegotiate  the terms of our long-term debt or to refinance
all or a portion of our  long-term  debt.  We cannot assure you that we would be
able to renegotiate successfully those terms or refinance our debt when required
or that the terms of the  refinancing  would be acceptable to management.  If we
were  unable  to  refinance  our  debt  or  obtain  new  financing  under  these
circumstances,  we would  have to  consider  other  options  such as the sale of
certain  assets  to meet  our debt  service  obligations,  the  sale of  equity,
negotiations with our lenders to restructure debt or other options.

Restrictive Debt Covenants

The indentures for the 7.50% notes and our other  outstanding  senior notes (the
"Senior Note Indentures") and our senior credit  facilities  impose  significant
operating  and  financial  restrictions  on  us  and  our  subsidiaries.   These
restrictions  may  significantly  limit or prohibit us from  engaging in certain
transactions, including the following:

 o  borrowing additional money,

 o  paying  dividends  or  other  distributions  to  stockholders,   

 o  allowing subsidiaries  to guarantee our debt,

 o  limiting the ability of  subsidiaries to make payments to us,

 o  making certain investments, 

 o  creating certain liens on our  assets, 

 o  selling  certain  assets, 

 o  entering  into  transactions  with affiliates, and

 o  engaging in certain mergers or consolidations.

These  restrictions  could limit our ability to obtain  future  financing,  make
needed capital  expenditures,  withstand a future downturn in our business or in
the economy or otherwise conduct necessary corporate activities. Under the terms
of the indenture for the 7.50% notes,  we have no obligation to comply with most
of the  covenants  during any  period  when the 7.50%  notes have been  assigned
investment  grade  ratings.  If the 7.50% notes later lose an  investment  grade
rating,  the  covenants  will again apply,  but actions taken during that period
generally  cannot  cause  us to be in  default  if the  covenants  again  become
effective. As a result, the protection afforded by the covenants could be

                                                          22

<PAGE>



weakened  if  the  7.50%  notes  are  assigned   investment  grade  ratings  and
subsequently downgraded to non-investment grade.

Our failure to comply with the  restrictions in our other  indentures and credit
facilities  could  lead to a default  under the  terms of those  documents.  Our
senior  credit  facilities  also require us and certain of our  subsidiaries  to
maintain  specified  financial  ratios and satisfy certain  financial tests. Our
ability  to meet these  financial  ratios  and tests may be  affected  by events
beyond our control and, as a result,  there can be no assurance  that we will be
able to meet  those  tests.  In the event of a default  under any of our  senior
credit  facilities,  the applicable lenders could terminate their commitments to
lend to us or  accelerate  the loans and declare all  amounts  borrowed  due and
payable. Borrowings under other debt instruments that contain cross-acceleration
or cross-default  provisions may also be accelerated and become due and payable.
If any of these  events  occurs,  we cannot  assure you that we would be able to
make the  necessary  payments to the lenders and cannot assure you that we would
be  able  to  find  alternate  financing.  Even  if we  could  obtain  alternate
financing,  we cannot assure you that it would be on terms that are favorable or
acceptable to us.

Completing the Qwest Network and Increasing Traffic Volume

Our objective is to become a leading  facilities-based  provider of  multi-media
communications  services  to  businesses,  consumers  and  other  communications
providers.  Our  ability  to  achieve  this  objective  will  depend  largely on
completion  of our  18,450  route-mile  fiber  optic  communications  network on
schedule and within budget, on maintaining the rights of way for our network and
on achieving substantial volumes on our network. The construction of our network
will be affected by many factors, such as weather and regulatory approvals, that
are beyond our  control.  We cannot  assure you that our entire  network will be
completed  on schedule  and within  budget.  Although  we believe  that our cost
estimates and build-out schedule are reasonable,  the actual  construction costs
or time  required to complete our network  could exceed  current  estimates.  In
addition, we must substantially  increase our current traffic volume in order to
realize the anticipated cash flow,  operating  efficiencies and cost benefits of
the network. We cannot assure you that we will be able to achieve this increased
traffic volume.

Operating Losses and Working Capital Deficits

We have had operating  losses and have not had enough cash flow from  operations
to allow us to meet our debt  service  requirements,  capital  expenditures  and
other cash needs.  We had a net loss of $822.6 million for the nine months ended
September 30, 1998 (or $30.9 million  excluding  non-recurring  costs associated
with  recent   acquisitions   and  provisions   for   in-process   research  and
development).  We had an accumulated deficit of approximately  $854.5 million at
September 30, 1998.

We had a working capital deficit of approximately $49.5 million at September 30,
1998 and working capital deficits for each of the four fiscal years before 1998.
We expect total capital expenditures for the year ending December 31, 1999

                                                          23

<PAGE>



to be approximately $1.3 billion to $1.4 billion. Working capital deficits could
limit our cash resources,  resulting in reduced liquidity.  We cannot assure you
that our operations will be profitable in the future. We may require  additional
capital in order to offset  operating losses and working capital deficits and to
support  our  objectives.   Certain  debt   instruments  to  which  we  and  our
subsidiaries  are parties limit but do not prohibit the incurrence of additional
indebtedness,  and we expect additional indebtedness to be incurred by us or our
subsidiaries  in the future.  We cannot assure you that we will be successful in
obtaining  additional  borrowings  when  required,  or that the  terms of future
indebtedness will not impair our ability to develop our business.

Competition

The  communications  industry is highly  competitive.  Many of our  existing and
potential competitors have financial,  personnel,  marketing and other resources
that  are  significantly  greater  than  ours,  as  well  as  other  competitive
advantages.   Increased   consolidation   and   strategic   alliances   in   the
telecommunications  industry resulting from the  Telecommunications  Act of 1996
also could give rise to significant new competitors.

The  success  of  our   business   plan  depends  on  our  ability  to  increase
significantly our share of the communications  services market in the medium and
long term.  Our  primary  competitors  in this  market are other  communications
service  providers,  including  large and small  facilities-based  interexchange
carriers.  For high-volume  capacity  services,  we compete primarily with other
coast-to-coast  and regional fiber optic network  providers.  AT&T, MCI WorldCom
and Sprint  currently  are the three  principal  facilities-based  long distance
fiber optic networks.  We are aware that others are planning additional networks
that, if constructed,  could employ similar advanced  technology as our network.
In  addition,  we have sold dark fiber  along  major  portions of our network to
Frontier  Corporation  and GTE  Corporation.  Upon  completion  of our  network,
Frontier and GTE will each have a fiber network  smaller than ours in geographic
scope with potential  operating  capability equal to ours. Another competitor is
constructing,  and has already  obtained a significant  portion of the financing
for,  a  fiber  optic  network.  As  publicly  announced,   the  scope  of  this
competitor's  network  is less than  ours.  Nevertheless,  we  expect  that this
competitor's  network  will  compete  directly  with  ours  for many of the same
customers where their and our routes overlap.  A carrier's  carrier announced in
January 1998 that it plans to sell wholesale capacity on its fiber optic network
and  that it has  entered  into an  agreement  with one of the  local  telephone
companies  established as a result of the AT&T  divestiture in 1984 known as the
regional  bell  oerating  cmpanies to be the  primary  user of its  network.  We
believe that this network,  although  potentially  competitive,  is different in
operating   capability  from  ours.   Another   potential   competitor,   a  new
telecommunications   company,   has   announced   its   intention  to  create  a
telecommunications network based on Internet technology.

In the switched services segment of the communications  services market, we sell
switched services to businesses, consumers and other communications carriers. In
this market, we compete with facilities-based carriers such as AT&T, MCI

                                                          24

<PAGE>



WorldCom and Sprint, all of which have extensive experience in the long distance
market, and some of the regional  carriers.  We compete in the switched services
market  on the  basis  of  price,  transmission  quality,  network  reliability,
customer service and support.  Our ability to compete effectively in this market
depends on our ability to maintain  high quality  services at prices equal to or
below those charged by our major competitors.  The  Telecommunications  Act will
allow  the  regional  bell  operating  companies  and  others  to enter the long
distance  market.  We  cannot  assure  you  that we  will  be  able  to  compete
successfully  with existing or new  competitors in our  communications  services
markets.  Our  failure  to do so would  have a  material  adverse  effect on our
business, financial condition and results of operations.

Dependence on Significant Customers

We have substantial business relationships with a few large customers, primarily
for the sale of dark fiber. Frontier, GTE and WorldCom (prior to its merger with
MCI) accounted for approximately 9%, 10% and 2%, respectively, of total revenues
for the nine months ended  September  30, 1998,  approximately  31%, 37% and 6%,
respectively,  of total  revenues  in 1997 and  approximately  26%,  0% and 28%,
respectively,  of total  revenues in 1996.  Revenues from these large  customers
were attributable primarily to construction contracts for the sale of dark fiber
that  extend  through  1998 or into 1999.  In 1997,  we  entered  into two large
construction  contracts  for the sale of dark fiber to GTE. Our  contracts  with
Frontier and GTE provide for reduced  payments and varying  penalties if we make
late  deliveries of route  segments.  These  contracts also allow the purchaser,
after  grace  periods  ranging  generally  from 12 to 18  months,  to  drop  the
non-delivered  segments from the system route to be  delivered.  In those cases,
the purchaser  would not pay us for that portion of the contract  purchase price
allocated  to the  non-delivered  segments.  A failure  by any of our dark fiber
purchasers to pay the full contract purchase price due to either the purchaser's
breach or our failure to deliver  certain  segments on time would  require us to
seek  alternative  funding  sources  for  capital  expenditures.  A  significant
reduction  in the level of services  we provide  for any of our large  customers
could have a material  adverse  effect on our results of operations or financial
condition.

We have generated  substantial  revenues from dark fiber sales.  However, as our
network is  completed,  we  anticipate  that revenues from dark fiber sales will
substantially  decrease in the future.  Our  business  plan assumes that we will
increase  our  revenue  from  communications  services  operations  to fund  the
expansion of our network. We are aware that certain  interexchange  carriers are
constructing or considering new networks. Accordingly, we cannot assure you that
any of our customers will increase their use of our services, or will not reduce
or cease their use of our services which could have a material adverse effect on
our ability to fund the completion of our network.

Managing Rapid Growth

Part of our strategy is to achieve  rapid growth by using our network to exploit
opportunities  that we expect  will  result from  regulatory  and  technological
changes and other industry developments. Our growth strategy also

                                                        25

<PAGE>



includes exploring opportunities for strategic  acquisitions.  We have completed
five acquisitions  since our initial public offering,  including the acquisition
of  LCI  in  June  1998  for   approximately   $3,930.5  million  and  Icon  for
approximately $254.1 million in our common stock. As result of our strategy,  we
are  experiencing   rapid  expansion  that  we  expect  will  continue  for  the
foreseeable  future.  This growth has  increased our  operating  complexity.  To
manage our expansion effectively we must:

 o   expand,  train and manage our employee  base, and attract and retain highly
     skilled personnel;

 o   expand and improve our systems for  serving  and  communicating with our
     customers;

 o  continue  to develop  and market new  products  and  services;  o  integrate
    acquired operations with our existing operations; and

 o  control  expenses related to the expansion of our business.

We cannot  assure you that we will be able to  satisfy  these  requirements,  or
otherwise manage our growth  effectively,  and any failure to do so could have a
material  adverse  effect on our  business,  financial  condition and results of
operations.

Pricing Pressures and Industry Capacity

The long  distance  transmission  industry  generally has had  overcapacity  and
falling prices since shortly after the AT&T divestiture in 1984. We believe that
increasing  demand in the last  several  years has  resulted  in a  shortage  of
capacity and slowed the decline in prices.  However,  we also expect that prices
for communications services will continue to fall over the next several years.
This is due primarily to:

      (1) recent  technological  advances  that permit  large  increases  in the
          transmission capacity of both new and existing fiber; and

      (2) strategic  alliances  or  similar  transactions,  such  as  purchasing
          alliances for long distance  capacity  among  regional bell  operating
          companies that increase the parties' purchasing power.

Also, our existing and future construction  contracts for the sale of dark fiber
with other  carriers will  increase  supply of capacity and may lower prices for
traffic on our network. These downward pressures on prices could have a material
adverse  effect on our business and on our  financial  condition  and results of
operations, including our ability to fund future operations.

Year 2000 Risks

Many existing computer systems,  including  hardware and software,  use only the
last two digits to identify a year.  As a result,  as the year 2000  approaches,
those 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 our
computer systems use only two digits to define the year, these defective systems
may cause disruptions in the network operations through which we provide

                                                          26

communications   services  to  customers   and  in  our   internal   operations.
Additionally,  we are  dependent  on outside  sources to provide  communications
services to customers and to bill customers for the services.  The greatest risk
to our 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
that we rely on in providing long distance telecommunications service.

We have established a year 2000 compliance group. The objective of the year 2000
compliance  group is to eliminate  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 the 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 our domestic  operations
and, to a lesser extent, on our international operations.

In addition to reviewing  our 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 software  applications  is complete.
Testing and deployment of corrected software systems is scheduled for completion
by June 30, 1999.

Inventory  and  assessment of hardware  systems,  including  network  computing,
network  systems  engineering  and  corporate   facilities,   is  scheduled  for
completion by January 31, 1999.  Upgrades  necessary to complete  remediation of
these  systems are expected to be in place by April 30,  1999.  Testing of these
system  upgrades is scheduled to be  completed  by May 31, 1999.  Deployment  of
these system upgrades is scheduled for completion by June 30, 1999.

The Company's  ability to meet the target dates discussed above depends on third
parties for  operational  testing,  as well as the Company's  overall efforts to
integrate the operations of recently acquired  businesses,  including LCI. Thus,
various factors,  including the compliance efforts of third parties,  over which
the Company has no control, may affect these target dates.

We are  developing  contingency  plans in the event that we fail to be year 2000
compliant. We expect the contingency plans to be completed by June 1999.

We  estimate  the SG&A  expenses  of  implementing  our year  2000  plan will be
approximately  $5.0  million to $7.0  million for the year ending  December  31,
1998. During the nine months ended September 30, 1998, we incurred approximately

                                                          27

<PAGE>



$3.0 million for year 2000 compliance costs, included in SG&A expense. We expect
to incur an  additional  approximately  $15.0  million to $20.0  million in SG&A
expense in 1999 to implement our year 2000 plan.

Rapid Technological Changes

The  telecommunications  industry is subject to rapid and significant changes in
technology.  For instance,  recent technological advances permit large increases
in the transmission capacity of both new and existing fiber. The introduction of
new  products  or  emergence  of new  technologies  also may reduce the cost and
increase  the supply of certain  services  similar to those  provided  by us. We
believe  that  for  the  foreseeable  future  technology  changes  will  neither
materially  affect the continued use of fiber optic cable nor materially  hinder
our  ability  to  acquire  necessary   technologies.   However,  the  effect  of
technological  changes on our  operations  cannot be predicted  and could have a
material  adverse  effect on our  business,  financial  condition and results of
operations.

Regulation Risks

Our  operations  are  subject  to  extensive   federal  and  state   regulation.
Communications  services are subject to the provisions of the Communications Act
of 1934, as amended (the "Communications Act"), including the Telecommunications
Act  and  the FCC  regulations  under  the  Communications  Act.  Communications
services  also are  covered by laws and  regulations  of the  states,  including
regulation  by public  utility  commissions  ("PUCs") and other state  agencies.
Generally, we must obtain and maintain certificates of authority from regulatory
bodies in most states where we offer  intrastate  services.  We also must obtain
prior  regulatory  approval  of tariffs for our  intrastate  services in most of
these jurisdictions.

Regulation  of the  telecommunications  industry  is changing  rapidly,  and the
regulatory environment varies substantially from state to state. As deregulation
at the federal level occurs,  some states are reassessing the level and scope of
regulation that may be applicable to us. Some of our operations are also subject
to various  environmental,  safety,  health and other governmental  regulations.
Future  regulatory,  judicial or  legislative  activities  could have a material
adverse effect on us.

The  Telecommunications  Act may have  potentially  significant  effects  on our
operations.  The  Telecommunications  Act allows  the  regional  bell  operating
companies  to enter the long  distance  business  and  enables  other  entities,
including  entities  affiliated with power utilities and ventures  between local
exchange carriers and cable television  companies,  to provide an expanded range
of telecommunications  services. Entry of these companies into the long distance
business would result in substantial  additional  competition in  communications
services.  This may have a material  adverse effect on us and our customers that
are communications services providers themselves. However, we believe that entry
by the regional bell  operating  companies and other  companies  into the market
will  create  opportunities  for  us  to  sell  fiber  or  lease  long  distance
high-volume capacity.

                                                          28

<PAGE>



We monitor  compliance with federal,  state and local regulations  governing the
discharge and disposal of hazardous  and  environmentally  sensitive  materials,
including the emission of electromagnetic  radiation.  We believe that we are in
compliance with these regulations;  however, any discharge, disposal or emission
could have a material adverse effect on us.

Reliance on Key Personnel

Our operations are managed by key executive  officers.  The loss of any of these
executive  officers could have a material  adverse effect on us. We believe that
our growth and future success will depend in large part on our continued ability
to attract and retain highly skilled and qualified  personnel.  The  competition
for qualified personnel in the telecommunications industry is intense. We cannot
assure you that we will be able to hire or retain necessary personnel.  The loss
of certain key members of senior management or the failure to recruit additional
qualified  personnel  in the future  could  significantly  impede our ability to
complete the  integration  of acquired  businesses  and to attain our financial,
expansion, marketing and other objectives.

Concentration of Voting Power; Potential Conflicts of Interest

Philip F.  Anschutz,  a  director  and  Chairman  of Qwest,  beneficially  owned
approximately  46.1% of the issued  and  outstanding  shares of Common  Stock at
December 31,  1998.  Mr.  Anschutz  continues to have the power to elect all the
directors  of Qwest  and to  control  the vote on all other  matters,  including
significant  corporate  actions.  Also,  Mr.  Anschutz  is a director  and holds
approximately 5% of the stock of Union Pacific Railroad Company. Subsidiaries of
that company own railroad  rights of way on which a  significant  portion of our
network has been and will be built.

Liquid Trading Market for the 7.50% Notes May Not Develop

There  is no  established  trading  market  for the  7.50%  notes.  The  initial
purchaser of the 7.50% notes has informed us that it currently intends to make a
market in the new 7.50% notes.  However, the initial purchaser has no obligation
to do so and may  discontinue  making a market at any time  without  notice.  In
addition,  the  liquidity  of any trading  market in the 7.50% notes will depend
upon a number of factors including:

- - the number of holders of the 7.50% notes;

- - the overall market for similar securities;

- - our financial performance and prospects; and

- - prospects for companies in our industry generally.

As a result, we cannot assure you that an active trading market will develop for
the 7.50% notes.

                              THE EXCHANGE OFFER

Purpose of the Exchange Offer

The Company  originally  issued and sold the old 7.50% notes on November 4, 1998
in an offering that was exempt from  registration  under the  Securities  Act in
reliance upon the exemptions  provided by Section 4(2), Rule 144A and Regulation
S of the Securities Act. Accordingly, the old 7.50% notes may not be transferred
in the  United  States  unless so  registered  or unless an  exemption  from the
registration  requirements of the Securities Act and applicable state securities
laws is available.

As a condition to the sale of the 0ld 7.50%  notes,  the Company and the initial
purchaser of the old 7.50% notes entered into the  Registration  Agreement as of
November 4, 1998.  In the  Registration  Agreement,  the Company  agreed that it
would (i) file with the Commission a Registration Statement under the Securities
Act with  respect to the new 7.50% notes by February 2, 1999;  (ii) use its best
efforts to cause the Registration  Statement to be declared  effective under the
Securities Act by March 3, 1999; and (iii) close an offer of the new 7.50% notes
in exchange for surrender of the old 7.50% notes by April 2, 1999. We have filed
a copy of the Registration Agreement as an exhibit to the Registration Statement
of which this prospectus is a part. The Registration Statement satisfies certain
of the Company's  obligations under the Registration  Agreement and the Purchase
Agreement.

Resale of the New Notes

Based on  no-action  letters  issued  by the  staff of the  Commission  to third
parties,  the Company  believes  that the new 7.50% notes issued in the exchange
offer in exchange  for old 7.50%  notes would in general be freely  transferable
after the exchange offer without further  registration  under the Securities Act
if  the  holder  of  the  new  7.50%  notes  represents  (i)  that  it is not an
"affiliate," as defined in Rule 405 of the Securities Act, of the Company,  (ii)
that it is acquiring the new 7.50% notes in the ordinary  course of its business
and  (iii)  that it has no  arrangement  or  understanding  with any  person  to
participate in the  distribution  (within the meaning of the Securities  Act) of
the new 7.50% notes; provided that, in the case of broker-dealers,  a prospectus
meeting  the  requirements  of the  Securities  Act is  delivered  if  required.
However, the Commission has not considered this exchange offer in the context of
a  no-action  letter  and  there  can be no  assurance  that  the  staff  of the
Commission  would make a similar  determination  with  respect to this  exchange
offer.  Holders of old 7.50% notes  wishing to accept this  exchange  offer must
represent to the Company that the conditions  have been met. Each  broker-dealer
that  receives  new 7.50%  notes for its own account  pursuant to this  exchange
offer,  where it acquired the old 7.50% notes  exchanged for the new 7.50% notes
for its own account as a result of  market-making  or other trading  activities,
may be deemed to be an  "underwriter"  within the meaning of the  Securities Act
and must  acknowledge  that it will deliver a prospectus in connection  with the
resale of the new 7.50%  notes.  The  letter of  transmittal  states  that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
This prospectus, as it may be amended or

                                                          30

<PAGE>



supplemented  from time to time,  may be used by a  broker-dealer  in connection
with  resales of new 7.50% notes  received in exchange for old 7.50% notes where
the  old  7.50%  notes  were  acquired  by  the  broker-dealer  as a  result  of
market-making  activities  or other trading  activities.  The Company has agreed
that, for a period of one year after closing of the exchange offer, it will make
this prospectus  available to any  broker-dealer  for use in connection with any
such resale.  A  broker-dealer  that  delivers a  prospectus  to  purchasers  in
connection  with  resales  will be subject  to  certain  of the civil  liability
provisions  under the Securities Act, and will be bound by the provisions of the
Registration  Agreement  (including  certain  indemnification  and  contribution
rights and obligations). See "Plan of Distribution."

Terms of the Exchange Offer; Period for Tendering Old 7.50% Notes

Upon the terms and subject to the conditions set forth in this prospectus and in
the  accompanying  letter of  transmittal  (which  together make up the exchange
offer),  the Company  will accept for exchange any and all old 7.50% notes which
are properly  tendered on or prior to the  Expiration  Date and not withdrawn as
permitted  below.  The Company will issue $1,000 principal amount at maturity of
new 7.50% notes in  exchange  for each  $1,000  principal  amount at maturity of
outstanding  old 7.50% notes  surrendered  pursuant to the exchange  offer.  Old
7.50% notes may be tendered only in integral multiples of $1,000.

The form and terms of the new 7.50%  notes are the same as the form and terms of
the old 7.50% notes except that (i) the exchange  will be  registered  under the
Securities  Act and hence the new 7.50% notes will not bear legends  restricting
their  transfer,  (ii) the  interest,  interest  rate  step-up,  original  issue
discount  and  cash  interest  provisions  will be  modified  or  eliminated  as
appropriate  and (iii)  holders of the new 7.50%  notes will not be  entitled to
certain rights of holders of old 7.50% notes under the  Registration  Agreement,
which rights with respect to old 7.50% notes will  terminate upon the closing of
the exchange  offer.  The new 7.50% notes will evidence the same debt as the old
7.50% notes (which they  replace) and will be issued  under,  and be entitled to
the benefits of, the same indenture.

As of the date of this  prospectus,  an aggregate of  $750,000,000  in principal
amount at  maturity  of the old 7.50%  notes is  outstanding.  This  prospectus,
together  with  the  letter  of  transmittal,  is first  being  sent on or about
February __, 1999, to all holders of old 7.50% notes known to the Company.

Holders of the old 7.50% notes do not have any appraisal or  dissenters'  rights
under the indenture in connection with the exchange  offer.  The Company intends
to  conduct  the  exchange  offer  in  accordance  with  the  provisions  of the
Registration Agreement and the applicable requirements of the federal securities
laws. See "Description of the 7.50% Notes--Exchange Offer; Registration Rights."

The Company  expressly  reserves the right, at any time or from time to time, to
extend the period of time during which the exchange  offer is open,  and thereby
delay  acceptance for exchange of any old 7.50% notes,  by giving written notice
of the extension to the holders as described  below.  During the extension,  all
old 7.50% notes  previously  tendered will remain  subject to the exchange offer
and

                                                          31

<PAGE>



may be accepted for  exchange by the  Company.  Any old 7.50% notes not accepted
for exchange for any reason will be returned  without  expense to the  tendering
holder as promptly as practicable after the expiration of the exchange offer.

The Company  reserves the right to amend or terminate the exchange  offer if any
of the  conditions  of the  exchange  offer  specified  below  under  "--Certain
Conditions of the Exchange Offer" occur. The Company will give written notice of
any extension, amendment, nonacceptance or termination to the holders of the old
7.50% notes as promptly as practicable. Any extension to be issued by means of a
press  release or other  public  announcement  will be issued no later than 9:00
a.m.,  New York  City  time,  on the next  business  day  after  the  previously
scheduled Expiration Date.

Procedures for Tendering Old 7.50% Notes

The tender to the  Company of old 7.50% notes by a holder as set forth below and
the  acceptance  by the  Company  will  create a binding  agreement  between the
tendering  holder and the Company  upon the terms and subject to the  conditions
set forth in this  prospectus  and in the  accompanying  letter of  transmittal.
Except as set forth  below,  a holder who  wishes to tender old 7.50%  notes for
exchange  pursuant to the exchange offer must send a completed and signed letter
of  transmittal,  including  all  other  documents  required  by the  letter  of
transmittal, to the exchange agent at one of the addresses set forth below under
"--Exchange  Agent" on or before the  Expiration  Date. In addition,  either (i)
certificates  for the old 7.50%  notes must be received  by the  exchange  agent
along  with  the  letter  of  transmittal,  or (ii) a timely  confirmation  of a
book-entry  transfer including an Agent's Message (a "Book-Entry  Confirmation")
of the old 7.50% notes, if the procedure is available, into the exchange agent's
account at The Depository  Trust Company (the  "Book-Entry  Transfer  Facility")
pursuant to the procedure  for  book-entry  transfer  described  below,  must be
received by the exchange agent before the  Expiration  Date, or (iii) the holder
must comply with the guaranteed delivery procedures described below.

The method of delivery of old 7.50% notes,  letters of transmittal and all other
required  documents is at the election and risk of the holders.  If the delivery
is by mail, it is recommended  that  registered  mail,  properly  insured,  with
return  receipt  requested,  be used.  In all cases,  sufficient  time should be
allowed to assure timely delivery.  No letters of transmittal or old 7.50% notes
should be sent to the Company.

Any  beneficial  owner  whose old 7.50%  notes are  registered  in the name of a
broker,  dealer,  commercial  bank,  trustee or other  nominee and who wishes to
tender should contact the registered  holder of the old 7.50% notes promptly and
instruct the registered  holder to tender on behalf of the beneficial  owner. If
the beneficial  owner wishes to tender on its own behalf,  the beneficial  owner
must, prior to completing and executing the letter of transmittal and delivering
its old 7.50% notes, either make appropriate  arrangements to register ownership
of the old 7.50%  notes in the  beneficial  owner's  name or  obtain a  properly
completed power of attorney from the registered  holder of old 7.50% notes.  The
transfer  of record  ownership  may take  considerable  time.  If the  letter of
transmittal is signed by

                                                          32

<PAGE>



a person or persons other than the registered holder of the old 7.50% notes, the
old 7.50%  notes  must be  endorsed  or  accompanied  by  appropriate  powers of
attorney,  in either case signed  exactly as the name of the  registered  holder
that appears on the old 7.50% notes.

Signatures  on a  letter  of  transmittal  or a  notice  of  withdrawal  must be
guaranteed  unless the old 7.50% notes surrendered for exchange pursuant thereto
are  tendered  (i) by a  registered  holder of the old  7.50%  notes who has not
completed the box entitled "Special Issuance  Instructions" or "Special Delivery
Instructions"  on the  letter  of  transmittal  or (ii)  for the  account  of an
Eligible  Institution  (as defined  below).  In the event that  signatures  on a
letter of  transmittal  or a notice of withdrawal are required to be guaranteed,
the  guarantees  must be by a firm  which is a member of a  registered  national
securities  exchange  or a member  of the  National  Association  of  Securities
Dealers,  Inc.  or  by  a  commercial  bank  or  trustee  having  an  office  or
correspondent in the United States (collectively,  "Eligible Institutions").  If
old 7.50% notes are  registered  in the name of a person  other than a signer of
the letter of transmittal,  the old 7.50% notes surrendered for exchange must be
endorsed  by,  or be  accompanied  by a written  instrument  or  instruments  of
transfer or exchange,  in satisfactory  form as determined by the Company in its
sole discretion,  signed by the registered holder with the signature  guaranteed
by an Eligible Institution.

All questions as to the validity,  form, eligibility (including time of receipt)
and  acceptance  of old 7.50% notes  tendered for exchange will be determined by
the Company in its sole  discretion,  and its  determination  shall be final and
binding.  The Company  reserves the absolute  right to reject any tenders of any
particular old 7.50% notes not properly tendered or not to accept any particular
old 7.50% notes whose  acceptance  might,  in the judgment of the Company or its
counsel, be unlawful.  The Company also reserves the absolute right to waive any
defects  or  irregularities  or  conditions  of  the  exchange  offer  as to any
particular old 7.50% notes either before or after the Expiration Date (including
the right to waive the ineligibility of any holder who seeks to tender old 7.50%
notes in the exchange offer).  The interpretation of the terms and conditions of
the exchange  offer as to any  particular old 7.50% notes either before or after
the Expiration Date  (including the letter of transmittal and its  instructions)
by the Company shall be binding on all parties.  Unless  waived,  any defects or
irregularities  in connection  with tenders of old 7.50% notes for exchange must
be cured  within a  reasonable  period of time as the Company  shall  determine.
Neither the Company,  the exchange agent nor any other person shall be under any
duty to give  notification  of any defect or  irregularity  with  respect to any
tender  of old  7.50%  notes  for  exchange,  nor  shall  any of them  incur any
liability for failure to give the notification.

If the letter of  transmittal  or any old 7.50% notes or powers of attorney  are
signed by trustees,  executors,  administrators,  guardians,  attorneys-in-fact,
officers  of  corporations  or others  acting in a fiduciary  or  representative
capacity,  those persons should so indicate when signing,  and, unless waived by
the Company,  proper evidence  satisfactory to the Company of their authority to
so act must be submitted.

<PAGE>



By tendering, each holder will represent to the Company, among other things, (i)
that it is not an  "affiliate," as defined in Rule 405 of the Securities Act, of
the Company, or if it is an affiliate,  it will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable,
(ii) that it is  acquiring  the new 7.50%  notes in the  ordinary  course of its
business  and (iii) at the time of the closing of the  exchange  offer it has no
arrangement or understanding  with any person to participate in the distribution
(within the meaning of the Securities Act) of the new 7.50% notes. If the holder
is a  broker-dealer  that will  receive  new 7.50%  notes for its own account in
exchange  for old 7.50% notes that were  acquired  as a result of  market-making
activities  or other  trading  activities,  the  holder  may be  deemed to be an
"underwriter"  within  the  meaning of the  Securities  Act and is  required  to
acknowledge  in the letter of  transmittal  that it will deliver a prospectus in
connection with any resale of the new 7.50% notes;  however, by so acknowledging
and by delivering a  prospectus,  the holder will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.

Acceptance of Old 7.50% Notes for Exchange; Delivery of New 7.50% Notes

Upon  satisfaction or waiver of all of the conditions to the exchange offer, the
Company will accept,  promptly  after the  Expiration  Date, all old 7.50% notes
properly  tendered and will issue the new 7.50% notes promptly after  acceptance
of the old 7.50% notes. See "--Certain  Conditions of the Exchange Offer" below.
For purposes of the exchange offer, the Company shall be deemed to have accepted
properly  tendered old 7.50% notes for exchange  when, as and if the Company has
given oral or written notice to the exchange agent, with written confirmation of
any oral notice to be given promptly after.

The new 7.50% notes will bear interest at the same rate and on the same terms as
the old 7.50%  notes.  Consequently,  cash  interest on the new 7.50% notes will
accrue at a rate of 7.50% per annum and will be payable  semiannually in arrears
commencing  on May 1, 1999 and  thereafter on November 1 and May 1 of each year.
Interest,  if any,  on each new 7.50% note will  accrue  from the last  interest
payment date on which interest was paid on the surrendered old 7.50% note or, if
no  interest  has been paid on the old 7.50%  note,  from the date on which cash
interest  on the old 7.50% note would  begin to  accrue.  Consequently,  holders
whose old 7.50% notes are accepted  for  exchange  will be deemed to have waived
the right to receive any accrued but unpaid interest on the old 7.50% notes.

In all  cases,  the  issuance  of new 7.50%  notes for old 7.50%  notes that are
accepted  for exchange  pursuant to the  exchange  offer will be made only after
timely receipt by the exchange agent of certificates  for the old 7.50% notes or
a timely  Book-Entry  Confirmation  of the old  7.50%  notes  into the  exchange
agent's  account at the  Book-Entry  Transfer  Facility,  a completed and signed
letter of  transmittal  and all other  required  documents.  If any tendered old
7.50%  notes  are not  accepted  for any  reason  set  forth  in the  terms  and
conditions  of the exchange  offer,  or if old 7.50% notes are  submitted  for a
greater  amount  than  the  holder  desires  to  exchange,   the  unaccepted  or
non-exchanged  old 7.50% notes will be returned without expense to the tendering
holder  (or, in the case of old 7.50% notes  tendered by  book-entry  procedures

Facility)  designated by the tendering  holder as promptly as practicable  after
the exchange offer expires or terminates.

Certain Conditions of the Exchange Offer

Notwithstanding  any other term of the exchange  offer,  the Company will not be
required to accept for  exchange,  or to issue new 7.50% notes in exchange  for,
any old 7.50% notes and may  terminate or amend the exchange  offer prior to the
Expiration Date, if because of any changes in law, or applicable interpretations
by the  Commission,  or  because  any  action or  proceeding  is  instituted  or
threatened  in any court or  governmental  agency with  respect to the  exchange
offer,  the Company  determines  that it is not permitted to effect the exchange
offer.

Holders may have  certain  rights and  remedies  against  the Company  under the
Registration Agreement should the Company fail to consummate the exchange offer,
notwithstanding a failure of the conditions  stated above.  These conditions are
not intended to modify those rights or remedies in any respect.

Book-Entry Transfer

The exchange agent will make a request to establish an account for the old 7.50%
notes at the  Book-Entry  Transfer  Facility for the  exchange  offer within two
business days after the date of this prospectus,  and any financial  institution
that is a participant in the  Book-Entry  Transfer  Facility's  systems may make
book-entry  delivery  of old 7.50%  notes by  causing  the  Book-Entry  Transfer
Facility to transfer  the old 7.50% notes into the exchange  agent's  account at
the Book-Entry  Transfer  Facility in accordance  with the  Book-Entry  Transfer
Facility's  procedures  for transfer.  However,  although  delivery of old 7.50%
notes may be effected  through  book-entry  transfer at the Book- Entry Transfer
Facility,  the letter of transmittal or facsimile,  or an Agent's Message,  with
any required signature guarantees and any other required documents, must, in any
case, be received by the exchange  agent at one of the addresses set forth below
under  "--Exchange  Agent" on or before the  Expiration  Date or the  guaranteed
delivery procedures described below must be complied with.

The term "Agent's Message" means a message,  transmitted by DTC to, and received
by, the exchange  agent and forming a part of a book-entry  confirmation,  which
states  that DTC has  received  an  express  acknowledgment  from the  tendering
participant  stating that the participant has received and agrees to be bound by
the terms of the letter of  transmittal,  and the Company may enforce the letter
of transmittal against the participant.

Guaranteed Delivery Procedures

If a  registered  holder of the old 7.50%  notes  wishes to tender the old 7.50%
notes and the old 7.50% notes are not  immediately  available,  or time will not
permit the  holder's  old 7.50% notes or other  required  documents to reach the
exchange  agent before the  Expiration  Date, or the  procedure  for  book-entry
transfer cannot be completed on time, a tender may be effected if (i) the tender
is made

in the form provided by the Company (by telegram, telex, facsimile transmission,
mail or hand delivery),  setting forth the name and address of the holder of the
old 7.50% notes and the amount of old 7.50%  notes,  stating  that the tender is
being made thereby and guaranteeing that within five trading days (on the Nasdaq
National  Market  after  the  date of  execution  of the  Notice  of  Guaranteed
Delivery,  the  certificates  for all  physically  tendered old 7.50% notes,  in
proper form for transfer, or a Book-Entry Confirmation,  and any other documents
required  by the  letter  of  transmittal  will  be  deposited  by the  Eligible
Institution  with  the  exchange  agent,  and  (iii)  the  certificates  for all
physically  tendered  old  7.50%  notes,  in  proper  form  for  transfer,  or a
Book-Entry  Confirmation  and all  other  documents  required  by the  letter of
transmittal,  are  received by the exchange  agent  within five Nasdaq  National
Market trading days after the date of signing the Notice of Guaranteed Delivery.

WITHDRAWAL RIGHTS

Tenders of old 7.50% notes may be withdrawn at any time prior to the  Expiration
Date.

For a  withdrawal  to be  effective,  a  written  notice of  withdrawal  must be
received by the  exchange  agent at one of the  addresses  set forth below under
"--Exchange Agent." Any notice of withdrawal must specify the name of the person
who tendered the old 7.50% notes to be  withdrawn,  identify the old 7.50% notes
to be  withdrawn  (including  the  amount of the old 7.50%  notes),  and  (where
certificates  for old 7.50%  notes have been  transmitted)  specify  the name in
which  the old  7.50%  notes  are  registered,  if  different  from  that of the
withdrawing  holder.  If certificates for old 7.50% notes have been delivered or
otherwise  identified to the exchange agent,  then,  prior to the release of the
certificates  the withdrawing  holder must also submit the serial numbers of the
particular  certificates  to be withdrawn and a signed notice of withdrawal with
signatures  guaranteed  by an  Eligible  Institution  unless  the  holder  is an
Eligible  Institution.  If old 7.50%  notes have been  tendered  pursuant to the
procedure for book-entry transfer described above, any notice of withdrawal must
specify the name and number of the account at the Book-Entry  Transfer  Facility
to be credited with the withdrawn old 7.50% notes and otherwise  comply with the
procedures  of  the  facility.  All  questions  as to  the  validity,  form  and
eligibility (including time of receipt) of the notices will be determined by the
Company whose determination  shall be final and binding on all parties.  Any old
7.50% notes so withdrawn  will be deemed not to have been  validly  tendered for
exchange for purposes of the exchange offer.  Any old 7.50% notes that have been
tendered for exchange but that are not exchanged for any reason will be returned
to the holder  without  cost to the holder  (or,  in the case of old 7.50% notes
tendered  by  book-entry  transfer  into the  exchange  agent's  account  at the
Book-Entry  Transfer  Facility  pursuant to the book-entry  transfer  procedures
described  above,  the old 7.50% notes will be  credited to an account  with the
Book-Entry  Transfer  Facility  specified by the holder) as soon as  practicable
after withdrawal, rejection of tender or termination of the exchange

result of the  exchange  offer.  The  expenses  of the  exchange  offer  will be
amortized over the term of the new 7.50% notes.

TRANSFER TAXES

Holders who tender  their old 7.50% notes for  exchange  will not be required to
pay any transfer taxes, except that holders who instruct the Company to register
new 7.50% notes in the name of, or request  that old 7.50% notes not tendered or
not  accepted  in the  exchange  offer be returned  to, a person  other than the
registered  tendering  holder  will be  responsible  for paying  any  applicable
transfer tax.

REGULATORY MATTERS

  The Company is not aware of any governmental or regulatory  approvals that are
required in order to complete the exchange offer.

CONSEQUENCES OF FAILURE TO EXCHANGE

Participation in the exchange offer is voluntary. Holders of the old 7.50% notes
are urged to  consult  their  financial  and tax  advisors  in making  their own
decisions on what action to take. See "Certain  United States Federal Income Tax
Considerations."

The old  7.50%  notes  that are not  exchanged  for the new  7.50%  notes in the
exchange offer will remain restricted securities.  Accordingly,  those old 7.50%
notes may only be  transferred  (A)(i)  to a person  who the  seller  reasonably
believes is a qualified institutional buyer under Rule 144A, (ii) in an offshore
transaction under Rule 903 or Rule 904 of Regulation S under the Securities Act,
or (iii)  under  Rule 144 under the  Securities  Act (if  available)  and (B) in
accordance  with all  applicable  securities  laws of the  states of the  United
States.  Under  certain  circumstances,  the Company is required to file a Shelf
Registration  Statement.  See "Description of the 7.50%  Notes--Exchange  Offer;
Registration Rights."

PAYMENT OF ADDITIONAL INTEREST UPON REGISTRATION DEFAULT

If a Registration Default (as defined) occurs,  additional interest ("Liquidated
Interest") will accrue on the 7.50% notes (in addition to the stated interest on
the 7.50%  notes)  from and  including  the date on which  any the  Registration
Default  shall  occur and to but  excluding  the date on which all  Registration
Defaults  have  been  cured.   Liquidated  Interest  will  be  payable  in  cash
semiannually  in arrears each  November 1 and May 1, at a rate per year equal to
0.50% of the  principal  amount at maturity of the 7.50% notes during the 90-day
period  immediately  following the  occurrence of the  Registration  Default and
shall  increase  by 0.25% per year of the  principal  amount at  maturity of the
7.50% notes at the end of each subsequent  90-day period,  but in no event shall
the rates exceed 2.0% per year in the aggregate regardless of the number of

                           DESCRIPTION OF THE 7.50% NOTES

GENERAL
   
The new 7.50% notes will be issued under an Indenture (the "Indenture")  between
the Company and Bankers  Trust  Company,  as trustee  under the  Indenture  (the
"Trustee").  Copies of the Indenture are available  from the Company on request.
For purposes of this  description of the 7.50% notes,  the term "Company" refers
to Qwest Communications International Inc. and does not include its subsidiaries
except for purposes of financial data  determined on a consolidated  basis.  For
purposes of this  description of the 7.50% notes,  the term "7.50% Notes" refers
to the new 7.50% notes and the old 7.50% notes together. The new 7.50% notes and
the old  7.50%  notes  are  considered  together  to be a single  class  for all
purposes under the Indenture,  including  waivers,  amendments,  redemptions and
Offers to Purchase.

The following summary of certain provisions of the Indenture is not complete and
is subject  to, and is  qualified  in its  entirety by  reference  to, the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"), and to all of the
provisions of the Indenture,  including the  definitions of certain terms in the
Indenture and those terms made a part of the Indenture by reference to the Trust
Indenture  Act, as in effect on the date of the  Indenture.  The  definitions of
certain  capitalized  terms used in the  following  summary  are set forth below
under "--Certain Definitions."

The new 7.50% notes will be senior unsecured obligations of the Company, ranking
equal  in  right of  payment  with all  existing  and  future  senior  unsecured
indebtedness of the Company,  including our 10 7/8% notes,  our 9.47% notes, our
8.29% notes,  our 7.25% Notes Due 2008 and our 7.25% Notes Due 2007, and will be
senior in right of  payment  to all  existing  and  future  indebtedness  of the
Company subordinated in right of payment to the 7.50% Notes. As of September 30,
1998,  the Company had $1,912.0  million of  indebtedness  outstanding,  none of
which was secured indebtedness or subordinated indebtedness.

The  operations  of the Company are  conducted  through  its  subsidiaries  and,
therefore,  the  Company  depends on cash flow from those  entities  to meet its
obligations.  The Company's  subsidiaries  will have no direct obligation to pay
amounts due on the 7.50% Notes and currently have no obligation to guarantee the
7.50% Notes. As a result,  the 7.50% Notes  effectively  will be subordinated to
all existing and future  third-party  indebtedness and other  liabilities of the
Company's subsidiaries  (including trade payables). As of September 30, 1998, on
a pro  forma  basis,  after  giving  effect  to the  acquisition  of  Icon,  the
redemption of $87.5 million of our 10 7/8% Notes, the repayment of $57.3 million
of the equipment credit facility, the offering of our 7.25% Notes Due 2008, this
offering of the 7.50% Notes and the use of the proceeds from the offerings,  the
total liabilities of the Company's  subsidiaries (after the elimination of loans
and advances by the Company to its subsidiaries)  would have been  approximately
$1,893.7  million,  of which  approximately  $32.0 million in  indebtedness  was
secured by the assets of the borrowing subsidiaries. See "Description of Certain
Indebtedness." The Company expects that it or its subsidiaries will incur

                                                          42

substantial  additional  debt in the  future.  Any rights of the Company and its
creditors, including the holders of 7.50% Notes, to participate in the assets of
any of the Company's  subsidiaries upon any liquidation or reorganization of any
subsidiary  will be subject to the prior claims of that  subsidiary's  creditors
(including  trade  creditors).   In  addition,  the  Company's  operations  have
generated  operating  losses in recent years, and there can be no assurance that
the  Company  will be able to  achieve or sustain  operating  profitability,  or
generate  sufficient  positive cash flow to pay the principal of and interest on
the 7.50% Notes. See "Risk Factors--Holding Company Structure;  Subordination of
the 7.50% Notes to Indebtedness  of  Subsidiaries,"  "Risk  Factors--Substantial
Indebtedness;  Ability to Incur Additional  Debt," and "Risk  Factors--Operating
Losses and Working Capital Deficits."

Principal, Maturity and Interest

The 7.50% Notes will be limited in aggregate  principal  amount to  $750,000,000
and will mature on November 1, 2008.  Interest on the 7.50% Notes will accrue at
a rate of 7.50% per year and will be  payable  semiannually  in arrears on May 1
and November 1 of each year, commencing May 1, 1999, to the holders of record on
the immediately  prior April 15 and October 15. Interest will be computed on the
basis of a 360-day year with twelve 30-day  months.  Principal of,  premium,  if
any, and interest on the 7.50% Notes will be payable, and the 7.50% Notes may be
exchanged or transferred,  at the office or agency of the Company, which, unless
otherwise  provided by the Company,  will be the offices of the Trustee.  At the
option of the Company,  interest  may be paid by check mailed to the  registered
holders at their  registered  addresses.  The 7.50% Notes will be issued without
coupons and in fully  registered form only, in minimum  denominations  of $1,000
and integral  multiples.  The 7.50% Notes will be issued only against payment in
immediately available funds. No service charge will be made for any registration
of transfer or exchange of the 7.50% Notes,  but the Company may require payment
sufficient  to cover  any  transfer  tax or other  similar  governmental  charge
payable.  The  interest  rate on the  7.50%  Notes is  subject  to  increase  as
described under "Exchange Offer;  Registration Rights" ("Liquidated  Interest").
All  references in this  description of the 7.50% Notes to interest on the 7.50%
Notes shall include Liquidated Interest, if appropriate.

Book-Entry System

The new 7.50% notes will  initially  be issued in the form of Global  Securities
(as defined in the Indenture) held in book-entry  form. The new 7.50% notes will
be  deposited  with  the  Trustee  as  custodian  for  the  Depository,  and the
Depository or its nominee will  initially be the sole  registered  holder of the
new 7.50% notes for all purposes under the Indenture. Except as set forth below,
a Global Security may not be transferred  except as a whole by the Depository to
a nominee of the Depository or by a nominee of the Depository to the Depository.

When a Global Security is issued,  the Depository or its nominee will credit, on
its  internal  system,  the  accounts  of  persons  holding  through it with the
respective  principal amounts of the individual  beneficial interest represented
by the Global  Security  purchased  by those  persons in the offering of the new
7.50% notes. The accounts will initially be designated by the initial  purchaser
of the new 7.50%  notes  with  respect to new 7.50%  notes  sold by the  initial
purchaser for the Company.

Ownership  of  beneficial  interests  in a Global  Security  will be  limited to
persons that have accounts with the Depository  ("participants") or persons that
may hold interests through  participants.  Ownership of beneficial  interests by
participants  in a Global  Security  will be shown on, and the  transfer of that
ownership  interest  will be effected only  through,  records  maintained by the
Depository  or its  nominee for the Global  Security.  Ownership  of  beneficial
interests in the Global Security by persons that hold through  participants will
be shown on, and the transfer of that ownership  interest within the participant
will occur only through, records maintained by the participant.

The laws of some  jurisdictions  require that certain  purchasers  of securities
take physical  delivery of the securities in definitive  form.  Those limits and
laws may make it more  difficult  to transfer  beneficial  interests in a Global
Security.  The Company will pay the principal of, premium,  if any, and interest
on new 7.50% notes  represented by any Global  Security to the Depository or its
nominee as the sole registered  owner and the sole holder of the new 7.50% notes
represented by the Global Security.  None of the Company, the Trustee, any agent
of the Company or the initial  purchaser  will have any  responsibility  for any
aspect of the  Depository's  reports  relating to or payments made on account of
beneficial  ownership interests in a Global Security  representing any new 7.50%
notes or for  maintaining,  supervising  or  reviewing  any of the  Depository's
records  relating to the  beneficial  ownership  interests.  The  Depository has
advised the Company that upon receipt of any payment of principal  of,  premium,
if any, or interest on any Global  Security,  the  Depository  will  immediately
credit,  on its book-entry  registration  and transfer  system,  the accounts of
participants  with  payments  in  amounts   proportionate  to  their  beneficial
interests in the  principal or face amount of the Global  Security,  as shown on
the records of the Depository. The Company expects that payments by participants
to owners of  beneficial  interests  in a Global  Security  held  through  those
participants will be governed by standing  instructions and customary  practices
as is now the case with  securities  held for customer  accounts  registered  in
"street name" and will be the sole responsibility of the participants.

So long as the  Depository or its nominee is the  registered  owner or holder of
the Global  Security,  the Depository or the nominee will be considered the sole
owner or holder of the new 7.50% notes  represented  by the Global  Security for
t3he purposes of receiving payment on the new 7.50% notes, receiving notices and
for all other purposes  under the Indenture and the new 7.50% notes.  Beneficial
interests in the new 7.50% notes will be evidenced  only by, and transfers  will
be  effected  only  through,  records  maintained  by  the  Depository  and  its
participants.  Except as provided  above,  owners of  beneficial  interests in a
Global  Security will not be entitled to and will not be considered  the holders
of the Global Security for any purposes under the Indenture.  Accordingly,  each
person  owning a  beneficial  interest  in a Global  Security  must  rely on the
procedures of the  Depository  and, if the person is not a  participant,  on the
procedures of the  participant  through  which the person owns its interest,  to
exercise any rights of a holder  under the  Indenture.  The Company  understands
that under existing  industry  practices,  if the Company requests any action of
holders or an owner of a beneficial  interest in a Global Security wants to take
any action that a holder is entitled to take under the Indenture, the Depository
would authorize the participants holding the beneficial interest to

                                                          44

<PAGE>



take that action, and the participants would authorize  beneficial owners owning
through  the  participants  to take the  action  or would  otherwise  act on the
instructions  of beneficial  owners  owning  through them.  The  Depository  has
advised  the  Company  that it will take any action  permitted  to be taken by a
holder of new 7.50% notes  (including  the  presentation  of new 7.50% notes for
exchange as described  below) only at the  direction of a  participant  to whose
account with the  Depository  interests in the Global  Security are credited and
only as to the portion of the aggregate  principal amount of the new 7.50% notes
as to which the participant has given that direction.

The Depository has advised the Company that the Depository is a  limited-purpose
trust  company  organized  under the  Banking  Law of the  State of New York,  a
"banking  organization"  within the meaning of New York Banking Law, a member of
the Federal Reserve System, a "clearing  corporation"  within the meaning of the
New York Uniform  Commercial Code and a "clearing  agency"  registered under the
Exchange  Act.  The  Depository  was  created  to  hold  the  securities  of its
participants  and to  facilitate  the  clearance  and  settlement  of securities
transactions  among  its  participants  in  the  securities  through  electronic
book-entry changes in accounts of the participants. This eliminated the need for
physical  movement of securities  certificates.  The  Depository's  participants
include securities brokers and dealers (including the initial purchaser), banks,
trust companies, clearing corporations and certain other organizations,  some of
whom  (and/or  their   representatives)  own  the  Depository.   Access  to  the
Depository's  book-entry  system is also  available  to  others,  such as banks,
brokers,  dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

Certificated New 7.50% Notes

New  7.50%  notes   represented  by  a  Global  Security  are  exchangeable  for
certificated new 7.50% notes only if:

     (i)  the Depository  notifies the Company that it is unwilling or unable to
          continue as a depository for the Global Security or if at any time the
          Depository ceases to be a registered  clearing agency, and a successor
          depository is not appointed by the Company within 90 days;

     (ii) the Company signs and delivers to the Trustee a notice that the Global
          Security shall be so transferable,  registrable and exchangeable,  and
          the transfer shall be registrable; or

    (iii) an Event of  Default or an event  which,  with the giving of notice or
          lapse of time or both,  would  constitute  an  Event of  Default  with
          respect to the new 7.50% notes  represented by the Global Security has
          occurred and is continuing.

Any Global  Security  that is  exchangeable  for  certificated  new 7.50%  notes
pursuant to the preceding  sentence will be  transferred  to, and registered and
exchanged  for,  certificated  new 7.50% notes in authorized  denominations  and
registered  in names  that the  Depository  or its  nominee  holding  the Global
Security  may  direct.  Subject  to the  foregoing,  a  Global  Security  is not
exchangeable,  except  for a  Global  Security  of the same  denomination  to be
registered in the name of the  Depository or its nominee.  If a Global  Security
becomes  exchangeable  for  certificated  new 7.50% notes,  (i) certificated new
7.50% notes will be issued only in fully  registered  form in  denominations  of
$1,000 or integral multiples,  (ii) payment of principal,  any repurchase price,
and  interest  on the  certificated  new 7.50%  notes will be  payable,  and the
transfer of the certificated new 7.50% notes will be registrable,

                                                          45

<PAGE>



at the office or agency of the Company maintained for that purposes and (iii) no
service  charge  will be made for any  issuance  of the  certificated  new 7.50%
notes, although the Company may require payment to cover any tax or governmental
charge imposed.  In addition,  the certificates will bear the legend referred to
under "Notice to Investors--Rule  144A" (unless the Company determines otherwise
in accordance with applicable law).

Optional Redemption

The 7.50% Notes will be subject to redemption  at the option of the Company,  in
whole or in part,  at any  time on not less  than 30 and not more  than 60 days'
prior notice at a redemption  price equal to the  principal  amount plus accrued
and  unpaid  interest  (if  any) to the  redemption  date  plus  the  Applicable
Make-Whole Premium.

For purposes of this "Optional Redemption" provision,  the following definitions
apply:

"Applicable  Make-Whole  Premium"  means,  with  respect to any 7.50% Note,  the
excess of (A) the present value at the redemption date of the required  interest
and  principal  payments due on the 7.50% Note,  computed  using a discount rate
equal to the Treasury Rate plus 37.5 basis points, over (B) the then outstanding
principal amount of the 7.50% Note.

"Treasury Rate" means,  with respect to any redemption  date, the rate per annum
equal to the semiannual  equivalent yield to maturity of the Comparable Treasury
Issue (as defined  below),  assuming a price for the  Comparable  Treasury Issue
(expressed  as a percentage of its  principal  amount)  equal to the  Comparable
Treasury Price (as defined below) for the redemption date.

"Comparable  Treasury Issue" means the United States Treasury  security selected
by a Reference  Treasury  Dealer (as defined below)  appointed by the Company as
having a maturity  comparable  to the  remaining  term of the 7.50%  Notes to be
redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the 7.50% Notes.

"Comparable Treasury Price" means, with respect to any redemption date,

     (i)  the average of the bid and asked  prices for the  Comparable  Treasury
          Issue (expressed in each case as a percentage of its principal amount)
          on the third business day preceding the redemption  date, as set forth
          in the daily statistical  release (or any successor release) published
          by the Federal Reserve Bank of New York and designated "Composite 3:30
          p.m. Quotations for U.S. Government Securities" or

    (ii)  if the release (or any successor release) is not published or does not
          contain the prices on that business day,

          (A) the  average  of the  Reference  Treasury  Dealer  Quotations  (as
          defined below) for the redemption  date,  after  excluding the highest
          and lowest such Reference Treasury Dealer Quotations, or

          (B) if the Company  obtains  fewer than four such  Reference  Treasury
          Dealer Quotations, the average of all such Quotations.

"Reference  Treasury Dealer  Quotations"  means,  with respect to each Reference
Treasury  Dealer and any  redemption  date,  the average,  as  determined by the
Company,  of the  bid  and  asked  prices  for  the  Comparable  Treasury  Issue
(expressed  in each case as a  percentage  of its  principal  amount)  quoted in
writing to the  Company by that  Reference  Treasury  Dealer at 5:00 p.m. on the
third business day preceding that redemption date.

"Reference  Treasury  Dealer" means each of Salomon  Smith Barney Inc.,  Merrill
Lynch,  Pierce,  Fenner  &  Smith  Incorporated,  Donaldson  Lufkin  &  Jenrette
Securities Corporation and Lehman Brothers Inc. and their respective successors;
provided, however, that if any of

                                                          46

the foregoing shall cease to be a primary U.S.  Government  securities dealer in
The City of New York (a "Primary Treasury Dealer"), the Company shall substitute
therefor another Primary Treasury Dealer.

Mandatory Redemption

  Except  as set  forth  under  "--Certain  Covenants--Change  of  Control"  and
"--Certain  Covenants--  Limitation on Asset  Dispositions,"  the Company is not
required to make  mandatory  redemption  payments or sinking fund  payments with
respect to the 7.50% Notes.

Certain Covenants

Suspended Covenants

  During  any  period  of time (a  "Suspension  Period")  that  

        (i) the  ratings
assigned to the 7.50% Notes by both the Rating  Agencies  are  Investment  Grade
Ratings and 

        (ii) no Default has occurred and is continuing under the Indentures,

the  Company  and  its  Restricted  Subsidiaries  will  not  be  subject  to the
provisions of the Indenture described below under:

       "--Limitation on Consolidated Debt,"

       "--Limitation on Debt and Preferred Stock of Restricted Subsidiaries,"

       "--Limitation  on  Restricted  Payments,"  

       "--Limitation  on  Dividend  and  Other  Payment  Restrictions  Affecting
          Restricted Subsidiaries,"

       "--Limitation on Issuances of Certain  Guarantees by, and Debt Securities
          of, Restricted Subsidiaries,"

       "--Limitation on Asset Dispositions," 

       "--Limitation  on  Issuances  and Sales of  Capital  Stock of  Restricted
          Subsidiaries,"

       "--Transactions with Affiliates and other Related Persons,"

       clause (ii) of "--Limitation on Sale and Leaseback Transactions" and 

       clause (d) of "--Mergers, Consolidations and Certain Sales of Assets" 

(collectively,  the  "Suspended  Covenants").  If the Company and its Restricted
Subsidiaries  are not subject to the  Suspended  Covenants  with  respect to the
7.50% Notes for any period of time as a result of the  preceding  sentence  and,
subsequently,  one or both Rating  Agencies  withdraws or downgrades the ratings
assigned to the 7.50% Notes below the required  Investment  Grade Ratings,  then
the  Company  and its  Restricted  Subsidiaries  will  again be  subject  to the
Suspended  Covenants and  compliance  with respect to  Restricted  Payments made
after the time of such  withdrawal or downgrade will be calculated in accordance
with the terms of the covenant  described below under  "Limitation on Restricted
Payments" as if the covenant had been in effect since the date of the Indenture.
Nevertheless, neither

    (a)   the  continued  existence,  after  the  date  of  such  withdrawal  or
          downgrade,  of  facts  and  circumstances  or  obligations  that  were
          Incurred or otherwise came into existence  during a Suspension  Period
          nor

    (b)   the performance of any such obligations,  shall constitute a breach of
          any covenant set forth in the Indenture or cause a Default or Event of
          Default thereunder; provided that

          (1) the  Company  and its  Restricted  Subsidiaries  did not  Incur or
          otherwise cause such facts and  circumstances  or obligations to exist
          in anticipation of a withdrawal or downgrade  below  investment  grade
          and

          (2) the Company  reasonably  believed that such  Incurrence or actions
          would not result in such a withdrawal or downgrade.

For  purposes of clauses  (1) and (2) in the prior  sentence,  anticipation  and
reasonable  belief may be  determined  by the Company and shall be  conclusively
evidenced  by a board  resolution  to that  effect  adopted in good faith by the
Board of Directors of the Company.

                                                          47

The Indenture contains, among others, the following covenants:

Limitation on Consolidated Debt. (a) The Company may not, and may not permit any
Restricted  Subsidiary  to, Incur any Debt,  unless,  after giving effect to the
application  of the proceeds of the Debt,  no Default or Event of Default  would
occur as a  consequence  of such  Incurrence  or be  continuing  following  such
Incurrence and either

        (i) the ratio of 

          (A) the aggregate consolidated principal amount of Debt of the Company
          outstanding  as of the  most  recent  available  quarterly  or  annual
          balance sheet, after giving pro forma effect to the Incurrence of such
          Debt and any other Debt  Incurred or repaid since such  balance  sheet
          date and the receipt and application of the proceeds of the Debt, to

          (B)  Consolidated  Cash Flow  Available for Fixed Charges for the four
          full fiscal  quarters next  preceding the  Incurrence of such Debt for
          which consolidated financial statements are available, determined on a
          pro forma basis as if any such Debt had been Incurred and the proceeds
          of the Debt had been  applied  at the  beginning  of such four  fiscal
          quarters,

would be less than 5.5 to 1.0 for Debt Incurred on or prior to April 1, 2000 and
5.0 to 1.0 for Debt Incurred thereafter, or

        (ii)   the  Company's  Consolidated  Capital Ratio as of the most recent
               available  quarterly or annual  balance  sheet,  after giving pro
               forma  effect to the  Incurrence  of such Debt and any other Debt
               Incurred or repaid since such balance  sheet date and the receipt
               and  application of the proceeds of the Debt, is less than 2.0 to
               1.0.

               As of  September  30,  1998,  on a pro forma basis  after  giving
               effect to the  acquisition of Icon, the offering of the old 7.50%
               notes,  the  offering  of the 7.25% Notes Due 2008 and the use of
               proceeds from the offerings,  the Company's  Consolidated Capital
               Ratio would have been approximately 0.6 to 1.0.

        (b)    Despite the foregoing limitation,  the Company and any Restricted
               Subsidiary may Incur any and all of the following  (each of which
               shall be given independent effect):

                (i) Debt under the 7.50% Notes, the Indenture and any Restricted
                    Subsidiary Guarantee;

                (ii)(A) Debt Incurred  subsequent to March 31, 1997 under Credit
                    Facilities  in an  aggregate  principal  amount  at any time
                    outstanding not to exceed $150 million plus

                    (B) Debt Incurred  subsequent to March 31, 1997 under one or
                    more Credit  Facilities that are revolving credit facilities
                    in an aggregate principal amount at any time outstanding not
                    to exceed the greater of

                                (x) $100  million or 

                        (y) 85% of Eligible Receivables;

               (iii)Purchase  Money  Debt,  provided  that  the  amount  of such
                    Purchase  Money Debt does not exceed 100% of the cost of the
                    construction,  installation,  acquisition  or improvement of
                    the applicable Telecommunications Assets;

               (iv) Debt owed by the Company to any Restricted Subsidiary of the
                    Company  or Debt  owed  by a  Restricted  Subsidiary  of the
                    Company to the  Company or a  Restricted  Subsidiary  of the
                    Company; provided, however, that upon either

                    (x) the  transfer or other  disposition  by such  Restricted
                    Subsidiary  or the  Company  of any Debt so  permitted  to a
                    Person   other  than  the  Company  or  another   Restricted
                    Subsidiary of the Company or

                    (y) the issuance (other than directors'  qualifying shares),
                    sale,  lease,  transfer  or other  disposition  of shares of
                    Capital Stock (including by consolidation or merger) of such
                    Restricted  Subsidiary to a Person other than the Company or
                    another such Restricted  Subsidiary,  the provisions of this
                    clause  (iv) shall no longer be  applicable  to the Debt and
                    the Debt shall be deemed to have been Incurred by the issuer
                    of  the  Debt  at  the  time  of  such   transfer  or  other
                    disposition;

                (v) Debt Incurred to renew, extend, refinance, defease or refund
                    (each, a  "refinancing")  the 7.50% Notes,  the notes issued
                    under the Senior Note Indentures or Debt of the Company

Incurred  pursuant  to  clause  (iii) of this  paragraph  (b),  in an  aggregate
principal  amount not to exceed the  aggregate  principal  amount of and accrued
interest on the Debt so refinanced plus the amount of any premium required to be
paid in connection  with such  refinancing  pursuant to the terms of the Debt so
refinanced  or the amount of any premium  reasonably  determined by the board of
directors of the Company as necessary to accomplish such refinancing by means of
a tender  offer or  privately  negotiated  repurchase,  plus the expenses of the
Company Incurred in connection with such refinancing;  provided,  however,  that
Debt the proceeds of which are used to  refinance  the 7.50% Notes or Debt which
is equal to the 7.50% Notes or Debt which is  subordinate in right of payment to
the 7.50% Notes shall only be permitted under this clause (v) if

                    (A) in the case of any  refinancing  of the  7.50%  Notes or
                    Debt which is equal to the 7.50% Notes, the refinancing Debt
                    is made equal to the 7.50% Notes or constitutes Subordinated
                    Debt,  and, in the case of any  refinancing of  Subordinated
                    Debt, the refinancing Debt constitutes Subordinated Debt and

                    (B) in any case, the  refinancing  Debt by its terms,  or by
                    the terms of any agreement or  instrument  pursuant to which
                    such Debt is issued,

                    (x) does not provide for  payments of  principal of the Debt

                    Affiliates, and customary subordination provisions governing
                    Debt owed to the Company or any Restricted Subsidiary;

              (iii) pursuant  to an  agreement  relating to any  Acquired  Debt,
                    which  encumbrance  or  restriction is not applicable to any
                    Person,  or the  properties  or assets of any Person,  other
                    than the Person so acquired;

              (iv)  pursuant to an  agreement  effecting  a renewal,  refunding,

                    to an agreement  referred to in clause (i), (ii) or (iii) of
                    this paragraph (b), provided,  however,  that the provisions

                    relating  to such  encumbrance  or  restriction  are no more
                    restrictive  in any  material  respect  than the  provisions
                    contained in the agreement the subject thereof;

                (v) in  the  case  of  clause  (iii)  of  paragraph  (a)  above,

                    a  Restricted   Subsidiary  otherwise  permitted  under  the
                    Indenture, but only to the extent such restrictions restrict
                    the  transfer  of the  property  subject  to  such  security
                    agreement;

               (vi) in  the  case  of  clause  (iii)  of  paragraph  (a)  above,

                    and   customary   restrictions   contained   in  asset  sale
                    agreements  limiting the transfer of such property or assets
                    pending the closing of such sale;

              (vii) any  restriction  with  respect to a  Restricted  Subsidiary
                    imposed pursuant to an agreement which has been entered into
                    for the sale or disposition of all or  substantially  all of
                    the Capital Stock or assets of such  Restricted  Subsidiary,
                    provided  that the  closing  of such  transaction  would not
                    result  in a  Default  or an Event  of  Default,  that  such
                    restriction   terminates   if   such   transaction   is  not
                    consummated  and that the  closing  or  abandonment  of such
                    transaction   occurs  within  one  year  of  the  date  such
                    agreement was entered into;

               (ix) pursuant to the Indenture,  the 7.50% Notes, the Senior Note
                    Indentures and the notes  outstanding  under the Senior Note
                    Indentures.

Subsidiary  to,  Incur or  suffer to exist  any Lien on or with  respect  to any

without  making,  or  causing  such  Restricted  Subsidiary  to make,  effective
provision for securing the 7.50% Notes (x) equally and ratably with such Debt as
to such property for so long as such Debt will be so secured or (y) in the event
such Debt is Debt of the Company which is subordinate in right of payment to the

will be so secured.

The foregoing restrictions shall not apply to:

                    the  improvements  financed by the proceeds of such Purchase

Restricted  Subsidiaries.   The  Company  may  not  (i)  permit  any  Restricted
Subsidiary  to,  directly or  indirectly,  guarantee any Debt  Securities of the

permit any Restricted Subsidiary to, directly or indirectly, enter into, assume,

Transaction,  other than a Sale and Leaseback Transaction between the Company or
a  Restricted  Subsidiary  on the one hand and a  Restricted  Subsidiary  or the
Company on the other hand, unless (i) the Company or such Restricted  Subsidiary
would be  entitled  to Incur a Lien to secure  Debt by reason of the  provisions
described  under   "--Limitation  on  Liens"  above,  equal  in  amount  to  the
Attributable  Value of the Sale and Leaseback  Transaction  without  equally and

provisions  concerning the application of Net Available  Proceeds) are satisfied

consideration  received in such Sale and Leaseback  Transaction as Net Available
Proceeds for purposes of such covenant.

Limitation  on Asset  Dispositions.  The Company may not, and may not permit any
Restricted  Subsidiary to, make any Asset Disposition unless: 

        (i)    the  Company or the  Restricted  Subsidiary,  as the case may be,
               receives consideration for such disposition at least equal to the
               Fair  Market  Value  for  the  assets  sold  or  disposed  of  as
               determined by the board of directors of the Company in good faith
               and  evidenced by a  resolution  of the board of directors of the
               Company filed with the Trustee; and

        (ii)   at least 75% of the consideration  for such disposition  consists
               of cash  or Cash  Equivalents  or the  assumption  of Debt of the
               Company (other than Debt that is subordinated to the 7.50% Notes)
               or of the Restricted Subsidiary and release from all liability on
               the Debt assumed.

If the aggregate  amount of Net Available  Proceeds  within any 12-month  period
exceeds $5 million, then all such Net Available Proceeds shall be applied within
360 days of the last such Asset Disposition

                (1) first, to the permanent  repayment or reduction of Debt then
                    outstanding  under any Credit  Facility,  to the extent such
                    agreements   would  require  such  application  or  prohibit
                    payments pursuant to clause (2) following;

                    price in cash  equal to 100% of the  principal  amount  plus
                    accrued and unpaid interest to the purchase date and, to the
                    extent required by its terms,  any other Debt of the Company
                    that is equal in ranking  with the 7.50% Notes at a price no
                    greater than 100% of the  principal  amount plus accrued and
                    unpaid  interest  to  the  purchase  date  (or  100%  of the
                    accreted value plus accrued and unpaid interest and premium,
                    if any, to the purchase  date in the case of original  issue
                    discount Debt);

                (3) third, to the extent of any remaining Net Available Proceeds
                    following the  completion  of the Offer to Purchase,  to the
                    repayment  of  other  Debt  of  the  Company  or  Debt  of a
                    Restricted  Subsidiary,  to the extent  permitted  under the
                    terms of the Debt; and

                (4) fourth,  to  the  extent  of  any  remaining  Net  Available
                    Proceeds,  to any other  use as  determined  by the  Company
                    which is not otherwise prohibited by the Indenture.

Subsidiary except

        (i)    a sale of all of the Capital Stock of such Restricted  Subsidiary
               owned by the Company and any Restricted  Subsidiary that complies
               with  the  provisions  described  under  "--Limitation  on  Asset
               Dispositions" above to the extent such provisions apply,

        (ii)   in a  transaction  that  results  in such  Restricted  Subsidiary
               becoming a Permitted Joint Venture, provided (x) such transaction
               complies with the provisions  described  under  "--Limitation  on
               Asset Dispositions" above to the extent such provisions apply and
               (y) the Company's  remaining  Investment in such Permitted  Joint

               replace or refund shares of Disqualified Stock of such Restricted
               Subsidiary,   provided   that  the  amounts  of  the   redemption
               obligations  of such  Disqualified  Stock  shall not  exceed  the
               amounts of the redemption  obligations of, and such  Disqualified
               Stock shall have  redemption  obligations  no earlier  than those

not permit any Restricted  Subsidiary to, enter into any  transaction (or series
of related  transactions)  with an  Affiliate  or Related  Person of the Company
(other than the Company or a Restricted  Subsidiary),  including any Investment,
unless such  transaction  is on terms no less  favorable  to the Company or such
Restricted  Subsidiary than those that could be obtained in a comparable  arm's-
length transaction with an entity that is not an Affiliate or Related Person and
is in the best interests of the Company or such Restricted Subsidiary,  provided
that the Company or any Restricted Subsidiary may enter into

        (i)    transactions  pursuant  to the  Company's  existing  tax  sharing
               agreement  entered into with Anschutz Company described under the
               caption "Certain  Relationships and Related  Transactions" in the
               Company's  annual report on Form 10-K for the year ended December
               31,  1997,  provided  that any  amendment  of,  supplement  to or
               substitute  for  such  agreement  is on  terms  that  are no less
               favorable to the Company or such Restricted  Subsidiary than such
               existing agreement,

        (ii)   transactions  pursuant  to  employee  compensation   arrangements
               approved  by  the  board  of  directors  of the  Company,  either
               directly or indirectly, and

        (iii)  Receivables Sales between the Company or a Restricted  Subsidiary
               and an  Affiliate of the Company or such  Restricted  Subsidiary,
               provided that such  Receivables  Sales satisfy the  provisions of
               clauses (i) and (ii) of "--Limitation on Asset Dispositions." For
               any  transaction  that involves in excess of $10 million but less
               than or equal to $15 million,  the Company  shall  deliver to the
               Trustee an Officers'  Certificate  stating  that the  transaction
               satisfies the above criteria.  For any transaction  that involves
               in excess of $15 million, a majority of the disinterested members
               of the board of directors of the Company shall determine that the
               transaction  satisfies the above criteria and shall evidence such
               a determination  by a board resolution filed with the Trustee or,
               in the event that there shall not be disinterested members of the
               board of directors with respect to the  transaction,  the Company
               shall file with the Trustee a written  opinion  stating  that the
               transaction  satisfies  the  above  criteria  from an  investment
               banking firm of national  standing in the United States which, in
               the good faith judgment of the board of directors of the Company,
               is independent with respect to the Company and its Affiliates and
               qualified to perform such task.

Change of Control.  Within 30 days of the occurrence of a Change of Control, the
Company  will be  required to make an Offer to Purchase  all  outstanding  7.50%
Notes at a price in cash  equal to 101% of the  principal  amount  of the  7.50%
Notes plus any accrued and unpaid  interest  thereon,  if any, to such  purchase
date. A "Change of Control" will be deemed to have occurred at such time as

        (x) a Rating  Decline shall have  occurred and 

        (y) either 

               (A)  the  sale,   conveyance,   transfer   or  lease  of  all  or
               substantially  all of the assets of the  Company to any Person or
               any Persons  acting  together that would  constitute a "group" (a
               "Group")  for  purposes  of Section  13(d) of the  Exchange  Act,
               together with any Affiliates or Related  Persons,  other than any
               Permitted  Holder  or  any  Restricted  Subsidiary,   shall  have
               occurred;

               (B) any Person or Group,  together with any Affiliates or Related
               Persons,  other  than  any  Permitted  Holder  or any  Restricted
               Subsidiary,  shall  beneficially  own (within the meaning of Rule
               13d-3 under the Exchange Act, except that a Person will be deemed
               to have  beneficial  ownership of all shares that such Person has
               the  right  to  acquire,   whether  such  right  is   exercisable
               immediately  or only  after the  passage of time) at least 50% of
               the aggregate  voting power of all classes of Voting Stock of the
               Company at a time when  Permitted  Holders own less than or equal
               to 25% of the  aggregate  voting  power of all  classes of Voting
               Stock of the Company; or

               (C)  during  any  period  of two  consecutive  years,  Continuing
               Directors  cease for any reason to  constitute  a majority of the
               Company's board of directors then in office. If the Company makes
               an Offer to Purchase  the 7.50%  Notes,  the  Company  intends to
               comply  with any  applicable  securities  laws  and  regulations,
               including any  applicable  requirements  of Section 14(e) of, and
               Rule 14e-1 under, the Exchange Act. The existence of the holders'
               right to require,  subject to certain conditions,  the Company to
               repurchase 7.50% Notes upon a Change of Control may deter a third
               party  from   acquiring  the  Company  in  a   transaction   that
               constitutes a Change of Control. If an Offer to Purchase is made,
               there can be no assurance  that the Company will have  sufficient
               funds to pay the Purchase  Price for all 7.50% Notes  tendered by
               holders  seeking to accept the Offer to  Purchase.  In  addition,
               instruments  governing other Debt of the Company may prohibit the
               Company  from  purchasing  any 7.50% Notes prior to their  Stated
               Maturity,  including  pursuant  to  an  Offer  to  Purchase.  See
               "Description  of Certain  Indebtedness."  If an Offer to Purchase
               occurs  at a time  when the  Company  does  not  have  sufficient
               available  funds to pay the  Purchase  Price for all 7.50%  Notes
               tendered  pursuant  to such Offer to  Purchase or a time when the
               Company is prohibited  from  purchasing  the 7.50% Notes (and the
               Company is unable  either to obtain the consent of the holders of
               the  relevant  Debt or to repay such  Debt),  an Event of Default
               would occur under the Indenture.  In addition,  one of the events
               that  constitutes  a Change of Control  under the  Indenture is a
               sale,  conveyance,  transfer or lease of all or substantially all
               of the property of the Company.

The  Indenture  will be  governed by New York law,  and there is no  established
definition  under  New  York  law of  "substantially  all"  of the  assets  of a
corporation.  Accordingly,  if the Company  were to engage in a  transaction  in
which it disposed of less than all of its assets,  a question of  interpretation
could arise as to whether such  disposition  was of  "substantially  all" of its
assets and whether the Company was required to make an Offer to Purchase. Except
as  described  in this  prospectus  with  respect  to a Change of  Control,  the
Indenture  does not contain any other  provisions  that permit  holders of 7.50%
Notes to require that the Company  repurchase or redeem 7.50% Notes in the event
of a takeover, recapitalization or similar restructuring.

Reports.  The  Company  will file with the Trustee on the date on which it files
them with the  Commission  copies of the annual and  quarterly  reports  and the
information,  documents,  and other reports that the Company is required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC

                                                          57

Reports").  If the  Company  shall  cease to be  required  to file  SEC  Reports
pursuant to the Exchange  Act, the Company  will  nevertheless  continue to file
such reports with the Commission  (unless the Commission  will not accept such a
filing) and the Trustee.  The Company will furnish  copies of the SEC Reports to
the  holders of 7.50% Notes at the time the Company is required to file the same
with the Trustee  and will make such  information  available  to  investors  who
request it in writing.

Limitation on  Designations  of  Unrestricted  Subsidiaries.  The Indenture will
provide that the Company will not designate any Subsidiary of the Company (other
than a newly created Subsidiary in which no Investment has previously been made)
as an "Unrestricted Subsidiary" under the Indenture (a "Designation") unless:

        (a)    no  Default  or Event  of  Default  shall  have  occurred  and be
               continuing  at  the  time  of or  after  giving  effect  to  such
               Designation;

        (b)    immediately after giving effect to such Designation,  the Company
               would  be able to  Incur  $1.00 of Debt  under  paragraph  (a) of
               "--Limitation on Consolidated Debt"; and

        (c)    the Company  would not be  prohibited  under the  Indenture  from
               making an  Investment  at the time of  Designation  (assuming the
               effectiveness of such Designation) in an amount (the "Designation
               Amount")  equal to the Fair Market Value of the net Investment of
               the Company or any other Restricted Subsidiary in such Restricted
               Subsidiary  on such date.  In the event of any such  Designation,
               the  Company   shall  be  deemed  to  have  made  an   Investment
               constituting  a  Restricted  Payment  pursuant  to  the  covenant
               "--Limitation  on  Restricted  Payments"  for all purposes of the
               Indenture in the Designation Amount.

The Indenture  will further  provide that neither the Company nor any Restricted
Subsidiary shall at any time

        (x)    provide  credit  support for, or a guarantee  of, any Debt of any
               Unrestricted Subsidiary (including any undertaking,  agreement or
               instrument  evidencing such Debt); provided that the Company or a
               Restricted  Subsidiary  may pledge  Capital  Stock or Debt of any
               Unrestricted  Subsidiary  on a  nonrecourse  basis  such that the
               pledgee has no claim whatsoever against the Company other than to
               obtain such pledged property,

        (y)    be directly or indirectly liable for any Debt of any Unrestricted
               Subsidiary or

        (z)    be directly or indirectly liable for any Debt which provides that
               the holder  may (upon  notice,  lapse of time or both)  declare a
               default thereon or cause the payment to be accelerated or payable
               prior to its final  scheduled  maturity upon the  occurrence of a
               default with respect to any Debt of any  Unrestricted  Subsidiary
               (including  any right to take  enforcement  action  against  such
               Unrestricted Subsidiary), except in the case of clause (x) or (y)
               to  the  extent  permitted  under   "--Limitation  on  Restricted
               Payments"  and   "--Transactions   with  Affiliates  and  Related
               Persons."

The  Indenture  will  further  provide  that a  Designation  may be  revoked  (a
"Revocation") by a resolution of the board of directors of the Company delivered
to the Trustee, provided that the Company will not make any Revocation unless:

        (a)    no  Default  or Event  of  Default  shall  have  occurred  and be
               continuing  at the  time  of and  after  giving  effect  to  such
               Revocation; and

        (b)    all Liens and Debt of such  Unrestricted  Subsidiary  outstanding
               immediately  following such Revocation would, if Incurred at such
               time,  have been  permitted  to be  Incurred at such time for all
               purposes of the Indenture.  All Designations and Revocations must
               be  evidenced  by  resolutions  of the board of  directors of the
               Company delivered to the Trustee  certifying  compliance with the
               foregoing provisions.

Mergers, Consolidations and Certain Sales of Assets

The  Company  may  not,  in  a  single   transaction  or  a  series  of  related
transactions,

        (i)    consolidate  with or merge  into any other  Person or  Persons or
               permit  any other  Person to  consolidate  with or merge into the

               Person  or in  which  the  Company  sells,  leases  or  otherwise
               disposes of all or  substantially  all of its assets to any other
               Person,  the  resulting   surviving  or  transferee  Person  (the
               "successor  entity")  is  organized  under the laws of the United
               States of America or any State or the  District of  Columbia  and
               shall expressly  assume,  by a supplemental  indenture signed and
               delivered to the Trustee in form satisfactory to the Trustee, all
               of the Company's respective obligations under the Indenture;

               transaction  and treating any Debt which becomes an obligation of
               the  Company  or a  Restricted  Subsidiary  as a  result  of such
               transaction  as  having  been  Incurred  by the  Company  or such
               Restricted Subsidiary at the time of the transaction,  no Default
               or Event of Default shall have occurred and be continuing;

               (c)  immediately  after giving  effect to such  transaction,  the
               Consolidated  Net Worth of the Company (or other successor entity
               to the  Company) is equal to or greater  than that of the Company
               immediately prior to the transaction;

               (d)  immediately  after  giving  effect to such  transaction  and
               treating any Debt which becomes an obligation of the Company or a

               provisions  of the Indenture  described  under  "--Limitation  on
               Liens" above,  the Company or the successor entity to the Company
               shall have secured the 7.50% Notes as required by said  covenant;

               (f) certain other conditions are met.

Certain Definitions

Set  forth  below is a summary  of  certain  of the  defined  terms  used in the
Indenture.  Reference is made to the  Indenture  for the full  definition of all
such  terms,  as well as any other  terms used in this  prospectus  for which no
definition is provided.

"Acquired  Debt" means,  with respect to any specified  Person,  (i) Debt of any
other  Person  existing  at  the  time  such  Person  merges  with  or  into  or
consolidates with or becomes a Subsidiary of such specified Person and (ii) Debt
secured by a Lien encumbering any asset acquired by such specified Person, which
Debt was not incurred in  anticipation  of, and was  outstanding  prior to, such
merger, consolidation or acquisition.

"Affiliate"  of any  Person  means  any  other  Person  directly  or  indirectly
controlling  or  controlled by or under direct or indirect  common  control with
such Person. For the purposes of this definition, "control" when used with

<PAGE>



respect to any Person means the power to direct the  management  and policies of
such Person,  directly or  indirectly,  whether  through the ownership of voting
securities,   by  contract  or  otherwise;   and  the  terms  "controlling"  and
"controlled" have meanings correlative to the foregoing.

"Asset  Disposition"  means  any  transfer,  conveyance,  sale,  lease  or other
disposition by the Company or any  Restricted  Subsidiary in one or more related
transactions  occurring within any 12-month period (including a consolidation or
merger or other sale of any such Restricted  Subsidiary with, into or to another
Person in a  transaction  in which  such  Restricted  Subsidiary  ceases to be a
Restricted  Subsidiary  of  the  Company,  but  excluding  a  disposition  by  a
Restricted  Subsidiary  to the  Company  or a  Restricted  Subsidiary  or by the
Company to a Restricted Subsidiary) of

        (i)  shares of Capital  Stock or other
ownership  interests of a Restricted  Subsidiary (other than as permitted by the
provisions of the Indenture  described in clauses (iii),  (iv) and (v) under the
caption  "--Limitation  on Issuances  and Sales of Capital  Stock of  Restricted
Subsidiaries"),

        (ii)  substantially  all of the assets of the Company or any  Restricted
Subsidiary representing a division or line of business or

        (iii) other
assets or rights of the  Company  or any  Restricted  Subsidiary  outside of the
ordinary course of business (excluding any transfer,  conveyance, sale, lease or
other  disposition  of equipment that is obsolete or no longer used by or useful
to the  Company,  provided  that the  Company  has  delivered  to the Trustee an
Officers'  Certificate  stating that such criteria are  satisfied);  provided in
each case that the aggregate consideration for such transfer,  conveyance, sale,
lease or other  disposition is equal to $500,000 or more in any 12-month  period
and provided further that the following shall not be Asset Dispositions:

                (x)
Permitted  Telecommunications  Capital  Asset  Dispositions,  

                (y)  exchanges  of
Telecommunications  Assets for other  Telecommunications  Assets  where the Fair
Market Value of the Telecommunications  Assets received is at least equal to the
Fair Market Value of the Telecommunications  Assets disposed of or, if less, the
difference is received in cash and such cash is Net Available Proceeds and

                (z)
Liens  permitted  to  be  Incurred   pursuant  to  the  second  paragraph  under
"--Limitation on Liens."

"Attributable Value" means, as to any particular lease under which any Person is
at the time liable other than a Capital Lease Obligation,  and at any date as of
which the amount is to be  determined,  the total net amount of rent required to
be paid by such Person under such lease during the initial term as determined in
accordance with generally accepted  accounting  principles,  discounted from the
last date of such initial term to the date of  determination at a rate per annum
equal  to the  discount  rate  which  would be  applicable  to a  Capital  Lease
Obligation  with like term in  accordance  with  generally  accepted  accounting
principles.  The net amount of rent required to be paid under any such lease for
any such period shall be the aggregate amount of rent payable by the lessee with
respect to such period after excluding amounts required to be paid on account of
insurance,  taxes, assessments,  utility,  operating and labor costs and similar
charges.  In the case of any lease  which is  terminable  by the lessee upon the
payment of penalty,  such net amount shall also include the lesser of the amount
of such  penalty  (in which case no rent shall be  considered  as required to be
paid under such lease subsequent to the first date

                                                          60

upon  which  it may be so  terminated)  or the rent  which  would  otherwise  be

amount of the Capital Lease Obligation.

"Capital  Lease  Obligation"  of any Person means the  obligation to pay rent or

right to use) real or personal  property of such Person  which is required to be
classified  and accounted for as a capital lease or a liability on the face of a
balance sheet of such Person in accordance  with generally  accepted  accounting
principles (a "Capital Lease").  The stated maturity of such obligation shall be
the date of the last  payment  of rent or any other  amount due under such lease
prior to the first date upon which  such lease may be  terminated  by the lessee
without payment of a penalty.  The principal  amount of the obligation  shall be
the  capitalized  amount of the  obligation  that would  appear on the face of a
balance sheet of such Person in accordance  with generally  accepted  accounting
principles.

"Capital   Stock"  of  any  Person   means  any  and  all   shares,   interests,
participations or other equivalents  (however  designated) of corporate stock or

               agency or instrumentality of the United States (provided that the
               full faith and credit of the United  States is pledged in support
               thereof  or the Debt  constitutes  a  general  obligation  of the
               country);

        (ii)   deposits,  certificates of deposit or acceptances with a maturity
               of 365 days or less of any financial institution that is a member

               capital and surplus and undivided profits (or any similar capital
               concept) of not less than $500 million and whose senior unsecured
               debt is rated at least "A- 1" by Standard & Poor's Corporation or
               "P-1" by Moody's Investors Service, Inc.;

        (iii)  commercial  paper with a maturity of 365 days or less issued by a
               corporation  (other than an Affiliate  of the Company)  organized
               under  the laws of the  United  States  or any State and rated at
               least "A-1" by Standard & Poor's  Corporation or "P-1" by Moody's
               Investors Service, Inc.; and

        (iv)   repurchase  agreements and reverse repurchase agreements relating
               to  marketable  direct   obligations  issued  or  unconditionally

               instrumentality of the United States and backed by the full faith
               and credit of the United States maturing within 365 days from the
               date of acquisition.

"Common  Stock" of any Person means  Capital  Stock of such Person that does not
rank prior,  as to the payment of dividends or as to the  distribution of assets
upon any voluntary or involuntary liquidation, dissolution or winding up of such
Person, to shares of Capital Stock of any other class of such Person.

more Wholly Owned Subsidiaries of such Person.

Events of Default

The following will be Events of Default under the Indenture:

        (a)    failure to pay  principal of (or  premium,  if any, on) any 7.50%
               Note when due;

        (b)    failure to pay any interest on any 7.50% Note when due, continued
               for 30 days;

        (c)default in the  payment of  principal  and  interest  on 7.50%  Notes
               required  to be  purchased  pursuant  to an Offer to  Purchase as
               described under "--Change of Control" when due and payable;

        (d)    failure to perform or comply with the provisions  described under
               "--Mergers, Consolidations and Certain Sales of Assets" and
               "--Limitation on Asset Dispositions";

        (e)    failure to perform any other covenant or agreement of the Company
               under the  Indenture  or the 7.50%  Notes  continued  for 60 days
               after written  notice to the Company by the Trustee or holders of
               at least 25% in  aggregate  principal  amount of the  outstanding
               7.50% Notes;

        (f)    default under the terms of any instrument  evidencing or securing
               Debt  of the  Company  or any  Restricted  Subsidiary  having  an
               outstanding  principal  amount of $10 million  individually or in
               the aggregate  which default  results in the  acceleration of the
               payment of such  indebtedness  or constitutes  the failure to pay
               such  indebtedness  when due (after  expiration of any applicable
               grace period);

        (g)    the  rendering of a final  judgment or judgments  (not subject to
               appeal)  against the Company or any  Restricted  Subsidiary in an
               amount in excess of $10

                                                          74

<PAGE>



               million which remains undischarged or unstayed for a period of 45
               days after the date on which the right to appeal has expired; and

        (h)    certain  events  of  bankruptcy,   insolvency  or  reorganization
               affecting the Company or any Restricted Subsidiary.

Subject to the provisions of the Indenture relating to the duties of the Trustee
in case an Event of Default  (as  defined)  shall occur and be  continuing,  the
Trustee will not be under any obligation to exercise any of its rights or powers
under the  Indenture  at the request or direction of any of the holders of 7.50%
Notes,  unless  such  holders  shall  have  offered  to the  Trustee  reasonable
indemnity.  Subject to such provisions for the  indemnification  of the Trustee,
the holders of a majority in aggregate principal amount of the outstanding 7.50%
Notes will have the right to direct the time, method and place of conducting any
proceeding  for any remedy  available to the Trustee or exercising  any trust or
power conferred on the Trustee.

If any Event of Default (other than an Event of Default  described in clause (h)
above)  shall occur and be  continuing,  either the Trustee or the holders of at
least 25% in aggregate  principal  amount at maturity of the  outstanding  7.50%
Notes may accelerate the maturity of all 7.50% Notes;  provided,  however,  that
after such acceleration,  but before a judgment or decree based on acceleration,
the holders of a majority in aggregate principal amount of the outstanding 7.50%
Notes may, under certain  circumstances,  rescind and annul such acceleration if
all Events of Default, other than the non-payment of accelerated principal, have
been  cured or waived  as  provided  in the  Indenture.  If an Event of  Default
specified  in clause (h) above  occurs,  the  outstanding  7.50% Notes will ipso
facto become immediately due and payable without any declaration or other act on
the part of the Trustee or any holder. For information as to waiver of defaults,
see "--Amendment, Supplement and Waiver."

No holder of any 7.50% Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder,  unless such holder shall
have  previously  given to the Trustee  written notice of a continuing  Event of
Default (as  defined)  and unless also the holders of at least 25% in  aggregate
principal amount of the outstanding  7.50% Notes shall have made written request
and offered reasonable  indemnity to the Trustee to institute such proceeding as
trustee,  and the Trustee shall not have received from the holders of a majority
in  aggregate  principal  amount  of the  outstanding  7.50%  Notes a  direction
inconsistent  with  such  request  and  shall  have  failed  to  institute  such
proceeding  within 60 days.  However,  such  limitations  do not apply to a suit
instituted  by a  holder  of a 7.50%  Note for  enforcement  of  payment  of the
principal of and premium, if any, or interest on such 7.50% Note on or after the
respective due dates  expressed in such 7.50% Note. The Company will be required
to furnish to the Trustee  quarterly a statement  as to the  performance  by the
Company of certain of its obligations  under the Indenture and as to any default
in such performance.

Amendment, Supplement and Waiver

The  Company and the  Trustee  may,  at any time and from time to time,  without
notice to or  consent  of any  holder  of 7.50%  Notes,  enter  into one or more
indentures supplemental to the Indenture 75

<PAGE>





        (1)    to evidence the  succession of another  Person to the Company and
               the  assumption by such successor of the covenants of the Company
               in the Indenture and the 7.50% Notes;

        (2)    to add to the  covenants of the  Company,  for the benefit of the
               holders,  or to surrender any right or power  conferred  upon the
               Company by the Indenture;

        (3) to add any additional Events of Default;

        (4)    to provide  for  uncertificated  7.50% Notes in addition to or in
               place of certificated 7.50% Notes;

        (5)    to evidence and provide for the acceptance of  appointment  under
               the Indenture of a successor Trustee;

        (6)    to secure the 7.50% Notes;  or 

        (7)    to cure any  ambiguity in the  Indenture to correct or supplement
               any provision in the Indenture which may be inconsistent with any
               other  provision in the Indenture or to add any other  provisions
               with respect to matters or questions arising under the Indenture;

provided such actions shall not adversely affect the interests of the holders in
any  material  respect.  With the  consent  of the  holders  of not less  than a
majority in principal amount of the outstanding 7.50% Notes, the Company and the
Trustee may enter into one or more indentures  supplemental to the Indenture for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the  provisions of the Indenture or modifying in any manner the rights of
the holders,  provided that no such  supplemental  indenture shall,  without the
consent of the holder of each outstanding 7.50% Note

               (1)  change  the  Stated  Maturity  of the  principal  of, or any
               installment  of  interest  on,  any  7.50%  Note,  or  alter  the
               redemption  provisions of the 7.50% Note, or reduce the principal
               amount of the 7.50% Note (or  premium,  if any),  or the interest
               thereon that would be due and payable upon  maturity of the 7.50%
               Note,  or  change  the  place of  payment  where,  or the coin or
               currency  in which,  any 7.50% Note or any  premium  or  interest
               thereon is payable, or impair the right to institute suit for the
               enforcement  of any such  payment on or after the maturity of the
               7.50% Note;

               (2) reduce the percentage in principal  amount of the outstanding
               7.50% Notes,  the consent of whose  holders is necessary  for any
               such  supplemental  indenture  or  required  for  any  waiver  of
               compliance  with certain  provisions  of the Indenture or certain
               Defaults thereunder;

               (3)  subordinate in right of payment,  or otherwise  subordinate,
               the 7.50% Notes to any other Debt; or

               (4) modify any  provision of this  paragraph  (except to increase
               any percentage set forth in this paragraph).

The holders of not less than a majority in principal  amount of the  outstanding
7.50% Notes may, on behalf of the holders of all the 7.50% Notes, waive any past
Default  under the  Indenture and its  consequences,  except  Default (1) in the
payment of the principal of (or premium,  if any) or interest on any 7.50% Note,
or (2) in respect of a covenant  or  provision  which  under the  proviso to the
prior paragraph  cannot be modified or amended without the consent of the holder
of each outstanding 7.50% Note affected.

Satisfaction and Discharge of the Indenture, Defeasance

The Company may terminate its  obligations  under the Indenture  when 

        (i)    either

               (A) all  outstanding  7.50%  Notes  have  been  delivered  to the
               Trustee for cancellation or

               (B) all such 7.50% Notes not theretofore delivered to the Trustee
               for cancellation have become due and payable, will become due and
               payable within one year or are to be called for redemption within
               one  year  under  irrevocable  arrangements  satisfactory  to the
               Trustee for the giving of notice of  redemption by the Trustee in
               the name and at the expense of the  Company,  and the Company has
               irrevocably  deposited or caused to be deposited with the Trustee
               funds in an amount  sufficient  to pay and  discharge  the entire
               indebtedness on

                                                          76

<PAGE>



               the 7.50%  Notes not  theretofore  delivered  to the  Trustee for
               cancellation,  for  principal  of (or  premium,  if any,  on) and
               interest to the date of deposit or maturity or date of redemption
               on such 7.50% Notes;

        (ii)   the Company has paid or caused to be paid all other sums  payable
               by the Company under the Indenture; and

        (iii)  the Company has delivered an Officers' Certificate and an Opinion
               of Counsel  relating to compliance  with the conditions set forth
               in the Indenture.

The Company,  at its election,  shall 

        (a)    be deemed to have paid and discharged its debt on the 7.50% Notes
               and the Indenture  shall cease to be of further  effect as to all
               outstanding  7.50% Notes (except as to (i) rights of registration
               of  transfer,  substitution  and  exchange of 7.50% Notes and the
               Company's right of optional redemption, (ii) rights of holders to
               receive  payments of principal of, premium,  if any, and interest
               on such 7.50% Notes (but not the Purchase Price referred to under
               "--Change of Control") and any rights of the holders with respect
               to such amounts, (iii) the rights,  obligations and immunities of
               the Trustee under the Indenture and (iv) certain other  specified
               provisions in the Indenture) or

        (b)    cease  to  be  under  any   obligation  to  comply  with  certain
               restrictive  covenants including those described under "--Certain
               Covenants," after the irrevocable deposit by the Company with the
               Trustee,  in trust for the  benefit of the  holders,  at any time
               prior to the maturity of the 7.50% Notes, of

               (A) money in an amount,

               (B) Government  Securities  which through the payment of interest
               and principal will provide, not later than one day before the due
               date of  payment  in  respect  of the  7.50%  Notes,  money in an
               amount, or

               (C) a combination,  sufficient to pay and discharge the principal
               of, and  interest  on, the 7.50%  Notes then  outstanding  on the
               dates on which any such payments are due in  accordance  with the
               terms of the Indenture and of the 7.50% Notes.

Such defeasance or covenant  defeasance shall be deemed to occur only if certain
conditions are satisfied, including, among other things, delivery by the Company
to the Trustee of an Opinion of Counsel  acceptable to the Trustee to the effect
that (i) such deposit,  defeasance and discharge  will not be deemed,  or result
in, a taxable event for federal income tax purposes with respect to the holders;
and (ii) the Company's deposit will not result in the Trust or the Trustee being
subject to regulation under the Investment Company Act of 1940, as amended.

Governing Law

The  Indenture  and the 7.50% Notes will be governed by the laws of the State of
New York.

The Trustee

Bankers  Trust  Company will be the Trustee  under the  Indenture and the Senior
Note Indentures.  The Trustee's current address is Four Albany Street, New York,
New York 10006.  The holders of not less than a majority in principal  amount of
the outstanding  7.50% Notes will have the right to direct the time,  method and
place of conducting any  proceeding  for exercising any remedy  available to the
Trustee,  subject to certain  exceptions.  Except during the  continuance  of an
Event of Default,  the Trustee will perform only such duties as are specifically
set forth in the  Indenture.  The  Indenture  provides  that in case an Event of
Default  shall occur (which  shall not be cured or waived),  the Trustee will be
required, in the exercise of its rights and powers under the Indenture, to use

                                                          77

<PAGE>



the  degree of care of a prudent  person in the  conduct  of such  person's  own
affairs.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director,  officer, employee,  incorporator or stockholder of the Company, as
such,  shall have any  liability  for any  obligations  of the Company under the
7.50%  Notes or the  Indenture  or for any claim  based on, in respect of, or by
reason of, such obligations or their creation, solely by reason of its status as
a director,  officer,  employee,  incorporator or stockholder of the Company. By
accepting a 7.50% Note each holder waives and releases all such  liability  (but
only such liability).  The waiver and release are part of the  consideration for
issuance of the 7.50% Notes.  Nevertheless,  such waiver may not be effective to
waive liabilities under the federal  securities laws and it has been the view of
the Commission that such a waiver is against public policy.

Transfer and Exchange

A holder may transfer or exchange 7.50% Notes in accordance  with the Indenture.
The Company,  the  Registrar  and the Trustee may require a holder,  among other
things,  to furnish  appropriate  endorsements  and transfer  documents  and the
Company  may  require  a holder to pay any  taxes  and fees  required  by law or
permitted by the Indenture.


EXCHANGE OFFER; REGISTRATION RIGHTS

The Company has entered into a  registration  rights  agreement with the initial
purchaser (the "Registration  Agreement")  pursuant to which the Company agreed,
for the benefit of the holders of the old 7.50% notes,  at the  Company's  cost,
(a) by February  2, 1999,  to file a  registration  statement  (a  "Registration
Statement")  with the Commission with respect to a registered  offer to exchange
the old 7.50%  notes for the new 7.50%  notes,  (b) to use its best  efforts  to
cause such Registration  Statement to be declared effective under the Securities
Act by March 3, 1999, and (c) to consummate the Exchange Offer by April 2, 1999.
For each old 7.50% note  surrendered  to the Company  pursuant  to the  Exchange
Offer,  the holder of such old 7.50% note will receive a new 7.50% note having a
principal amount at maturity equal to that of the surrendered old 7.50% note.

Based upon  no-action  letters  issued by the staff of the  Commission  to third
parties,  the Company  believes that the new 7.50% notes issued  pursuant to the
Exchange  Offer in  exchange  for old 7.50%  notes  would in  general  be freely
transferable  after the exchange offer without  further  registration  under the
Securities  Act if the holder of the new 7.50% notes  represents  (i) that it is
not an  "affiliate,"  as  defined  in Rule  405 of the  Securities  Act,  of the
Company, (ii) that it is acquiring the new 7.50% notes in the ordinary course of
its  business and (iii) that it has no  arrangement  or  understanding  with any
person to participate in the distribution  (within the meaning of the Securities
Act) of the new 7.50% notes;  provided  that, in the case of  broker-dealers,  a
prospectus  meeting the  requirements  of the  Securities  Act be  delivered  as
required.  However,  the Commission has not considered the exchange offer in the
context of a no-action letter and there can

                                                          78

<PAGE>



be no  assurance  that  the  staff  of  the  Commission  would  make  a  similar
determination with respect to the exchange offer as in such other circumstances.
Holders of old 7.50% notes wishing to accept the exchange  offer must  represent
to the Company  that such  conditions  have been met.  Each  broker-dealer  that
receives  new 7.50% notes for its own account  pursuant to the  exchange  offer,
where it acquired the old 7.50% notes exchanged for such new 7.50% notes for its
own account as a result of  market-making  or other trading  activities,  may be
deemed to be an "underwriter"  within the meaning of the Securities Act and must
acknowledge  that it will deliver a prospectus in connection  with the resale of
such new 7.50% notes. The letter of transmittal  states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it  is  an  "underwriter"  within  the  meaning  of  the  Securities  Act.  This
prospectus,  as it may be amended or supplemented from time to time, may be used
by a  broker-dealer  in connection  with resales of new 7.50% notes  received in
exchange  for old 7.50% notes  where such old 7.50% notes were  acquired by such
broker-dealer  as  a  result  of  market-making   activities  or  other  trading
activities.  The Company has agreed that, for a period of one year after closing
of  the  exchange  offer,  it  will  make  this  prospectus   available  to  any
broker-dealer  for use in connection with any such resale. A broker-dealer  that
delivers such a prospectus to purchasers in connection with such resales will be
subject to certain of the civil liability  provisions  under the Securities Act,
and will be bound by the  provisions of the  Registration  Agreement  (including
certain  indemnification  and  contribution  rights and  obligations).  See "The
Exchange Offer--Resale of the New 7.50% Notes" and "Plan of Distribution."

Each holder of the old 7.50% notes  (other than certain  specified  holders) who
wishes to exchange  old 7.50% notes for new 7.50%  notes in the  exchange  offer
will be required to represent that

        (a) it is not an affiliate of the Company,

        (b)    any new 7.50%  notes to be received by it will be acquired in the
               ordinary course of its business and

        (c)    at the time of  commencement  of the  Exchange  Offer,  it has no
               arrangement  with any person to participate  in the  distribution
               (within  the  meaning  of the  Securities  Act) of the new  7.50%
               notes.  If  the  holder  is  a  broker-dealer  (a  "Participating
               Broker-Dealer")  who  acquired  the old  7.50%  notes for its own
               account as a result of market-making or other trading activities,
               it may be deemed to be an "underwriter" within the meaning of the
               Securities Act and will be required to  acknowledge  that it must
               deliver a prospectus  meeting the  requirements of the Securities
               Act in  connection  with any resale of such new 7.50% notes.  The
               Commission   has   taken   the   position   that    Participating
               Broker-Dealers may fulfill their prospectus delivery requirements
               with  respect to the new 7.50%  notes  (other than a resale of an
               unsold  allotment  from the original sale of the old 7.50% notes)
               with the prospectus  contained in the exchange offer Registration
               Statement.  Under the  Registration  Agreement,  the  Company  is
               required to allow Participating Broker-Dealers and other persons,
               if any, subject to similar  prospectus  delivery  requirements to
               use the prospectus  contained in the exchange offer  Registration
               Statement in connection with the resale of such new 7.50% notes.

  If, 

        (i)    because of any change in law or applicable interpretations by the
               Commission's  staff,  the Company  determines  upon advice of its
               outside  counsel that it is not  permitted to effect the exchange
               offer as contemplated by the Registration Agreement, or

        (ii)   for any other reason the exchange offer is not consummated within
               180 days of the closing date of the old 7.50% notes, or


                                                          79

<PAGE>



        (iii)  the initial purchaser so requests with respect to old 7.50% notes
               held by it following closing of the exchange offer, or

        (iv)   any holder of old 7.50% notes  (other than the initial  purchaser
               of the old 7.50%  notes) is not  eligible to  participate  in the
               Exchange Offer or

        (v)    if the initial  purchaser  participates  in the exchange offer or
               acquires  new  7.50%  notes  issued  and  delivered  to it by the
               Company in exchange for old 7.50% notes,  such purchaser does not
               receive  freely  tradeable  new 7.50% notes in  exchange  for old
               7.50% notes constituting any portion of an unsold allotment,

the Company  will,  at its cost,  

               (a)  as  promptly  as  practicable,  file  a  shelf  registration
               statement (a "Shelf Registration  Statement") with the Commission
               relating  to the offer and sale of the old 7.50% notes or the new
               7.50% notes,

               (b)  cause  such  Shelf  Registration  Statement  to be  declared
               effective under the Securities Act and

               (c)  use  its  best  efforts  to  keep  such  Shelf  Registration
               Statement  continuously  effective under the Securities Act for a
               period of three years or such shorter  period that will terminate
               when all the old 7.50% notes or new 7.50% notes,  as  applicable,
               covered by such Shelf Registration Statement have been sold.

The Company  will, in the event of filing such a Shelf  Registration  Statement,
provide to each holder of the old 7.50% notes copies of the prospectus that is a
part of such Shelf  Registration  Statement,  notify  each such holder when such
Shelf  Registration  Statement  for the old 7.50%  notes has been filed with the
Commission  and when such Shelf  Registration  Statement  or any  post-effective
amendment  thereto has become  effective  and take certain  other actions as are
required to permit  unrestricted  resales of the 7.50% Notes.  A holder of 7.50%
Notes that sells such 7.50%  Notes  pursuant to a Shelf  Registration  Statement
generally  will be  required  to be named as a  selling  security  holder in the
related prospectus and to deliver a prospectus to purchasers, will be subject to
certain of the civil liability provisions under the Securities Act in connection
with  such  sales  and  will be  bound  by the  provisions  of the  Registration
Agreement   which  are   applicable   to  such  a  holder   (including   certain
indemnification and contribution rights and obligations).

The old 7.50% notes  provide  that if 

        (i)    the Registration Statement has not been filed with the Commission
               within 90 days after the  closing  date of the old 7.50% notes or
               declared  effective within 150 days after the closing date of the
               old 7.50% notes,  or the exchange offer has not been  consummated
               within 180 days after the closing date of the old 7.50% notes or

        (ii)   instead, the Shelf Registration Statement has not been filed with
               the Commission and declared  effective  within 210 days after the
               closing date of the old 7.50% notes or

        (iii)  after either the Registration Statement or the Shelf Registration
               Statement has been declared  effective,  as the case may be, such
               Registration  Statement  thereafter  ceases  to be  effective  or
               usable (subject to certain exceptions) in connection with resales
               of old 7.50%  notes or new  7.50%  notes in  accordance  with and
               during the periods specified in the Registration  Agreement (each
               such  event   referred  to  in  clauses  (i)  through   (iii),  a
               "Registration Default"),

additional interest  ("Liquidated  Interest") will accrue on the old 7.50% notes
(in addition to the stated  interest on the old 7.50% notes) from and  including
the date on which any such Registration  Default shall occur up to but excluding
the date on which all Registration Defaults have been cured. Liquidated Interest
will be payable in cash  semiannually in arrears each November 1 and May 1, at a
rate per annum  equal to 0.50% of the  principal  amount of the old 7.50%  notes
during  the  90-day  period   immediately   following  the   occurrence  of  any
Registration  Default  and shall  increase  by 0.25% per annum of the  principal
amount of the old 7.50% notes at the end of each subsequent 90-day period,

                                                          80

but in no event  shall  such  rates  exceed  2.00%  per  annum in the  aggregate
regardless of the number of Registration Defaults.

The  summary  in this  prospectus  of  certain  provisions  of the  Registration
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of the Registration  Agreement,

                       DESCRIPTION OF CERTAIN INDEBTEDNESS
   
In March 1997,  the Company sold $250.0  million in  principal  amount of its 10
7/8% Senior  Notes Due 2007 (the "10 7/8% Notes") and used the proceeds to repay
certain  indebtedness of the Company and also to fund capital  expenditures  for
the  construction  and  activation  of the  Company's  network.  The  Company is
amortizing  issuance costs totaling  approximately $8.0 million over the term of
the 10 7/8%  Notes.  Interest on the 10 7/8% Notes is payable  semi-annually  on
April 1 and  October 1 of each year,  beginning  on  October  1,  1997,  and the
principal  amount of the 10 7/8%  Notes is due and  payable  in full on April 1,
2007. The 10 7/8% Note Indenture  contains  certain  covenants that, among other
things,  limit the ability of the Company and certain of its  subsidiaries  (the
"Restricted  Subsidiaries") to incur additional indebtedness and issue preferred
stock, pay dividends or make other  distributions,  repurchase  capital stock or
subordinated indebtedness, create certain liens, enter into certain transactions
with  affiliates,  sell  assets of the Company or its  Restricted  Subsidiaries,
issue or sell capital stock of the Company's  Restricted  Subsidiaries  or enter
into certain  mergers and  consolidations.  In addition,  under certain  limited
circumstances,  the Company  will be  required to offer to purchase  the 10 7/8%
Notes at a price equal to 100% of the  principal  amount plus accrued and unpaid
interest  to the date of  purchase  with the excess  proceeds  of certain  asset
sales.  In the  event of a Change of  Control  (as  defined  in the 10 7/8% Note
indenture),  holders of the 10 7/8%  Notes  will have the right to  require  the
Company to  purchase  all of their 10 7/8% Notes at a price equal to 101% of the
aggregate principal amount plus accrued and unpaid interest.  Generally,  the 10
7/8% Notes are redeemable,  at the option of the Company, in whole or in part at
stated premiums over par on or after April 1, 2002, and up to 35% of the 10 7/8%
Notes  may be  redeemed  at a  premium  over par prior to April 1, 2000 with the
proceeds of certain public stock offerings.

  In August 1997,  the Company  completed a  registered  exchange of new 10 7/8%
Notes (with terms identical in all material respects to the originally issued 10
7/8% Notes) for all of the originally issued 10 7/8% Notes. The Company received
no proceeds from and  recognized no profit on the exchange  transaction,  and no
change in the  financial  condition  of the Company  occurred as a result of the
exchange  transaction.  In December 1998, the Company  redeemed $87.5 million of
its 10 7/8% Notes.

  In October  1997,  the Company  sold  $555.9  million in  principal  amount at
maturity of its 9.47% Senior Discount Notes Due 2007 (the "9.47% Notes"),

                                                          82

generating  net  proceeds  of  approximately  $342.1  million,  after  deducting
offering costs which are included in intangible and other  long-term  assets and
are being  amortized to interest  expense over the term of the 9.47% Notes.  The
Company  used the net  proceeds  to fund  capital  expenditures  for  continuing
construction and activation of the Company's  network and to fund further growth
in the  business.  The  9.47%  Notes  accrete  at a rate  of  9.47%  per  annum,
compounded semi-annually,  to an aggregate principal amount of $555.9 million by
October 15, 2002. The principal  amount of the 9.47% Notes is due and payable in
full on October  15,  2007.  The 9.47%  Notes are  redeemable  at the  Company's
option,  in whole or in part,  at any time on or  after  October  15,  2002,  at
specified  redemption  prices over par. In addition,  prior to October 15, 2000,
the  Company  may  use the net  cash  proceeds  from  certain  specified  equity
transactions  to  redeem up to 35% of the 9.47%  Notes at  specified  redemption
prices over par.  Cash interest on the 9.47% Notes will not accrue until October
15, 2002, and thereafter  will accrue at a rate of 9.47% per annum,  and will be
payable  semi-annually in arrears commencing on April 15, 2003 and thereafter on
April 15 and  October  15 (each an  interest  payment  date) of each  year.  The
Company has the option of commencing the accrual of cash interest on an interest
payment  date on or  after  October  15,  2000,  in which  case the  outstanding
principal  amount at maturity of the 9.47% Notes will, on such interest  payment
date, be reduced to the then accreted  value,  and cash interest will be payable
on each  interest  payment date  thereafter.  The  indenture for the 9.47% Notes
contains certain covenants that are substantially identical to the 10 7/8% Notes
described above.

  In March 1998, the Company completed a registered  exchange of new 9.47% Notes
(with terms  identical in all material  respects to the originally  issued 9.47%
Notes) for all of the  originally  issued 9.47% Notes.  The Company  received no
proceeds  from and  recognized  no profit on the  exchange  transaction,  and no
change in the  financial  condition  of the Company  occurred as a result of the
exchange transaction.

In January 1998, the Company sold $450.5 million in principal amount at maturity
of its 8.29% Senior Discount Notes Due 2008 (the "8.29% Notes"),  generating net
proceeds of approximately  $299.2 million,  after deducting offering costs which
are included in intangible and other  long-term  assets and will be amortized to
interest  expense  over the term of the 8.29%  Notes.  The Company  used the net
proceeds to fund capital expenditures for continuing construction and activation
of the Company's  network and to fund further growth in the business.  The 8.29%
Notes  accrete at a rate of 8.29% per  annum,  compounded  semi-annually,  to an
aggregate  principal amount of $450.5 million by February 1, 2003. The principal
amount of the 8.29% Notes is due and  payable in full on  February 1, 2008.  The
8.29% Notes are redeemable at the Company's  option, in whole or in part, at any
time on or after February 1, 2003, at specified  redemption  prices over par. In
addition,  prior to February 1, 2001,  the Company may use the net cash proceeds
from  certain  specified  equity  transactions  to redeem up to 35% of the 8.29%
Notes at specified  redemption prices over par. Cash interest on the 8.29% Notes
will not accrue until February 1, 2003, and thereafter  will accrue at a rate of
8.29% per annum,  and will be payable  semi-annually  in arrears  commencing  on
August 1, 2003 and  thereafter  on  February  1 and  August 1 (each an  interest
payment date) of each year. The Company has the option of commencing

                                                          83

the accrual of cash interest on an interest payment date on or after February 1,
2001, in which case the  outstanding  principal  amount at maturity of the 8.29%
Notes will,  on such  interest  payment  date,  be reduced to the then  accreted
value,  and  cash  interest  will be  payable  on  each  interest  payment  date
thereafter.  The indenture for the 8.29% Notes contains  certain  covenants that
are  substantially  identical to the 10 7/8% Notes and the 9.47% Notes described
above.

  In July 1998, the Company  completed a registered  exchange of new 8.29% Notes
(with terms  identical in all material  respects to the originally  issued 8.29%
Notes) for all of the  originally  issued 8.29% Notes.  The Company  received no
proceeds  from and  recognized  no profit on the  exchange  transaction,  and no
change in the  financial  condition  of the Company  occurred as a result of the
exchange transaction.

  In connection  with the acquisition of LCI, the Company assumed LCI's existing
debt  instruments,  including $350.0 million of 7.25% Senior Notes due 2007 (the
"7.25% Notes Due 2007").

In November 1998, the Company sold the 7.50% Notes and used the proceeds to fund
initiatives to further develop and deploy the Company's network, gain additional
market share in the traditional  telecommunications  market segment,  expand the
Qwest data market strategy and to fund general  working  capital needs.  Pending
the  application  of the net proceeds of the  offering of the 7.50%  Notes,  the
Company applied a portion of the proceeds to pay down the  outstanding  balances
under the Company's  existing  credit  facilities.  Unamortized  issuance  costs
totaling  approximately  $9.0 million are being  amortized  over the term of the
7.50% Notes.  Interest on the 7.50% Notes is payable  semi-annually on May 1 and
November 1 of each year,  commencing on May 1, 1999, and the principal amount of
the 7.50% Notes is due and payable in full on  November 1, 2008.  The  indenture
for the 7.50% Notes contains certain covenants that are substantially  identical
to the 10 7/8%  Notes,  the 9.47%  Notes and the 8.29%  Notes  described  above,
except  that  under  the  indenture  for the 7.50%  Notes,  the  Company  has no
obligation to comply with most of the covenants during any period when the 7.50%
Notes have been assigned investment grade ratings. If the 7.50% Notes later lose
an investment grade rating,  the covenants will again apply. See "Description of
the 7.50% Notes."

 In connection  with the sale of the 7.50% Notes,  the Company agreed to make an
offer to exchange new notes,  registered under the Securities Act and with terms
identical in all material  respects to the 7.50% Notes,  for the 7.50% Notes or,
alternatively, to file a shelf registration statement under the Act with respect
to the 7.50% Notes.

In late November 1998,  the Company sold $300.0  million in principal  amount of
its 7.25% Notes Due 2008 and used the  proceeds to fund  initiatives  to further
develop and deploy the Company's  network,  gain additional  market share in the
traditional  telecommunications  market  segment,  expand the Qwest data  market
strategy and to fund general working capital needs. These initiatives (which may
be  effected  directly  by the  Company or through  joint  venture  and  similar
arrangements) will include construction, development and

                                                          84

lighting of the  Company's  network,  expansion  of the data and other  business
services offered by the Company,  development of sales channels and other needs.
Unamortized  issuance  costs  totaling  approximately  $2.3  million  are  being
amortized over the term of the 7.25% Notes Due 2008. Interest on the 7.25% Notes
is payable semi-annually on May 1 and November 1 of each year, commencing on May
1, 1999, and the principal amount of the 7.25% Notes Due 2008 is due and payable
in full on November 1, 2008. The indenture for the 7.25% Notes contains  certain
covenants  that are  substantially  identical  to the 10 7/8%  Notes,  the 9.47%
Notes,  the 8.29% Notes and the 7.50% Notes described  above,  except that, like
the 7.50% Notes,  under the indenture for the 7.25% Notes Due 2008,  the Company
has no obligation  to comply with most of the  covenants  during any period when
the 7.25% Notes Due 2008 have been assigned  investment  grade  ratings.  If the
7.25% Notes Due 2008 later lose an investment  grade rating,  the covenants will
again apply.

  In connection with the sale of the 7.25% Notes Due 2008, the Company agreed to
make an offer to exchange new notes,  registered  under the  Securities  Act and
with terms  identical in all material  respects to the 7.25% Notes Due 2008, for
the  7.25%  Notes  Due  2008  or,  alternatively,  to file a shelf  registration
statement under the Securities Act with respect to the 7.25% Notes Due 2008.

Credit Facility and Lines of Credit

  In  connection  with the  acquisition  of LCI,  the  Company  assumed a $250.0
million  revolving  credit facility (the "Credit  Facility") from a syndicate of
banks.  The Company also assumed  three  separate  discretionary  line of credit
agreements  (the "Lines of Credit") with  commercial  banks  providing for total
borrowings of up to $75.0 million.

The Credit Facility bears interest at a rate  consisting of two components.  The
base  rate  component  is  dependent  upon a  market  indicator  and the  second
component  varies  from  0.30% to  0.75%,  based on the  more  favorable  of the
relationship of borrowings  levels to operating cash flow (the "leverage ratio")
or senior  unsecured  debt  rating.  As of September  30, 1998,  the Company had
$215.0  million  outstanding  under the Credit  Facility at an interest  rate of
6.0%. The Credit  Facility  contains  various  financial  covenants  including a
leverage  ratio  requirement.  As of  September  30,  1998,  the  Company was in
compliance with all Credit Facility covenants. In November 1998, the outstanding
balance under the Credit Facility was repaid with a portion of the proceeds from
the 7.50% Notes. The Credit Facility expired on December 31, 1998.

As of September 30, 1998,  $17.5 million was  outstanding on the Lines of Credit
at an interest rate of 6.3%. In November  1998, the  outstanding  balances under
the Lines of Credit were repaid  with a portion of the  proceeds  from the 7.50%
Notes.  Two of the Lines of Credit  expired on Dec. 31, 1998. As of December 31,
1998 the Company had $25.0 million available on the remaining Line of Credit.

On November 5, 1998, the Company signed a commitment  letter with its three lead
banks to syndicate an unsecured credit facility of between $500 million and $750
million.  The lead  banks  agreed to a minimum  aggregate  commitment  of $250.0
million and the Company expects the remainder will be provided by other banks to
be added to

                                                          85

the syndicate. After this, the Company sold $300.0 million of 7.25% Senior Notes
due 2008 and sold $200.0 million of common stock to Microsoft Corporation.  As a
result of these  transactions,  the  Company  postponed  closing  of the  credit
facility.  The Company is currently in the process of obtaining a new  unsecured
$750.0  million to $1.0 billion  credit  facility  through a syndicate of banks.
Closing of the new credit  facility is  conditioned,  among other  things,  on a
mutually  satisfactory credit agreement.  The Company and the syndicate of banks
are working toward closing in the first quarter of 1999.

Accounts Receivable Securitization

As of September 30, 1998, the Company, through its wholly-owned subsidiary, LCI,
maintained  an agreement to sell a  percentage  ownership  interest in a defined
pool of trade accounts  receivable  (the  "Securitization  Program").  Under the
Securitization Program, LCI SPC I, Inc. ("SPC"), a single-purpose  subsidiary of
the Company,  sold accounts receivable.  SPC had approximately $150.0 million of
accounts  receivable  available  for sale and had sold a total of  approximately
$125.0 million as of September 30, 1998.

In October 1998, the Company borrowed approximately $67.0 million under a demand
note payable to a bank. This demand note was utilized to reacquire the ownership
interest in a portion of the pool of trade  accounts  receivable  that were sold
under the  Securitization  Program.  The remaining  portion of such accounts was
reacquired with cash. In November 1998, the outstanding balance under the demand
note was repaid with a portion of the proceeds of the 7.50% Notes.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

   
General

The following is a general  discussion of certain of the expected  United States
federal income tax consequences applicable to holders of the old 7.50% notes who
purchased the old 7.50% notes from Qwest for cash,  exchange the old 7.50% notes
for new 7.50%  notes in this  exchange  offer,  and hold the old 7.50% notes and
will hold the new 7.50% notes as capital assets ("Holders").  This discussion is
a descriptive  summary only and is not a complete  technical analysis or listing
of all potential tax considerations  that may be relevant to Holders.  Qwest has
received an opinion of its counsel, Holme Roberts & Owen LLP, that the following
describes the material United States federal income tax consequences expected to
result to Holders,  subject to the conditions and limitations  described in this
discussion.  This  discussion  is based on current  provisions  of the  Internal
Revenue Code of 1986, as amended (the "Code"),  applicable Treasury  regulations
("Regulations"),  and public administrative and judicial  interpretations of the
Code and Regulations,  all of which are subject to change. Any such change could
be applied  retroactively.  This  discussion  is also  based on the  information
contained  in  this  prospectus  and  the  related  documents,  and  on  certain
representations from Qwest as to factual matters. This discussion does not cover
all aspects of United  States  federal  taxation that may be relevant to, or the
actual tax effect that any of the

                                                          87

<PAGE>



matters described in this discussion will have on,  particular  Holders and does
not address foreign, state, or local tax consequences.

Qwest has not  sought  and will not seek any ruling  from the  Internal  Revenue
Service (the "Service") with respect to the 7.50% notes.  The Service could take
a different  position  concerning  the tax  consequences  of the exchange of old
7.50% notes for new 7.50% notes or the ownership or disposition of the new 7.50%
notes, and the Service's position could be sustained by a court.

The United States federal income tax consequences to a Holder may vary depending
on the Holder's particular  situation or status. Some of the rules applicable to
Holders  that are  subject to  special  rules  under the Code are not  discussed
below.  Examples  of  these  holders  include  insurance  companies,  tax-exempt
organizations,  mutual funds, retirement plans, financial institutions,  dealers
in securities or foreign currency,  persons that hold the 7.50% notes as part of
a "straddle"  or as a "hedge"  against  currency  risk or in  connection  with a
conversion  transaction,  persons that have a functional currency other than the
United States dollar, investors in pass-through entities,  traders in securities
that  elect  to mark to  market,  and  except  as  expressly  addressed  in this
discussion, Non-U.S.
Holders (as defined below).

As used in this  discussion,  the term "U.S.  Holder"  means a Holder that,  for
United States federal income tax purposes, is

     (1) a citizen or resident of the United States,

     (2)   a corporation,  partnership,  or other entity created or organized in
           or under the laws of the United States,  of the District of Columbia,
           or of any State,

     (3)   an estate the income of which is  subject  to United  States  federal
           income tax, regardless of its source, or

     (4) a trust if

           (a)   a court  within the United  States is able to exercise  primary
                 supervision over the administration of the trust and

           (b)   one or more United States persons have the authority to control
                 all substantial decisions of the trust.

The term  "Non-U.S.  Holder" means a Holder that is, for United  States  federal
income tax purposes, not a U.S. Holder.

This discussion is for general  information  purposes only. Each holder is urged
to consult its tax advisor as to the particular tax  consequences to such person
of  exchanging  old 7.50% notes for new 7.50% notes and of holding and disposing
of the new 7.50% notes,  including the  applicability and effect of all foreign,
state,  or  local  tax laws  and of any  change  in  federal  income  tax law or
administrative or judicial interpretation since the date of this prospectus.


Exchange of Notes

Although  there is no direct  authority  as to whether the exchange of old 7.50%
notes for new 7.50%  notes in the  exchange  offer  will be treated as a taxable
exchange for United States  federal  income tax  purposes,  it is the opinion of
Holme  Roberts & Owen LLP,  counsel  to Qwest,  that  based on its  analysis  of
applicable  law, such exchange  should not be treated as a taxable  exchange for
United States federal income tax purposes. A Holder should not recognize gain or
loss on the  exchange  of old 7.50%  notes for new 7.50%  notes in the  exchange
offer and,  on such  exchange,  should have the same  adjusted  tax basis in and
holding  period  for the  new  7.50%  notes  as it had in the  old  7.50%  notes
immediately before the exchange.


Original Issue Discount

Qwest was  advised by the initial  purchaser  at the time of the sale of the old
7.50% notes that the initial purchaser intended to sell the old 7.50% notes at a
price equal to 99.324% of the stated  principal  amount of the old 7.50%  notes,
and Qwest  believes that  substantially  all of the old 7.50% notes were sold to
investors at that price.  This  discussion is therefore  based on the assumption
that the old 7.50%  notes  were not  issued  with an amount  of  original  issue
discount in excess of the de minimis  exception  under the Code, and thus,  that
the original  issue  discount  amount will be considered  zero for United States
federal income tax purposes. Each U.S. Holder is required to include stated

interest on the 7.50% notes in gross income in accordance with the U.S. Holder's
regular method of tax accounting.


Market Discount

Under the market discount rules of the Code, a U.S. Holder who purchases a 7.50%
note at a  "market  discount"  will  generally  be  required  to treat  any gain
recognized on the disposition of the 7.50% note as ordinary income to the extent
of the lesser of such gain or the portion of the market  discount  that  accrued
during the period that the U.S. Holder held such 7.50% note.  Market discount is
generally  defined as the amount by which a U.S.  Holder's  purchase price for a
7.50% note is less than the stated  redemption  price at  maturity  (the  stated
principal  amount  in this  case) of the  7.50%  note on the  date of  purchase,
subject to a statutory de minimis exception.  A U.S. Holder who acquires a 7.50%
note at a market  discount  may be  required  to defer all or a  portion  of any
interest expense that otherwise may be deductible on any  indebtedness  incurred
or  continued to purchase or carry such 7.50% note until the  retirement  of the
7.50%  note,  or if  earlier,  the U.S.  Holder  disposes of the 7.50% note in a
taxable  transaction.  A U.S.  Holder  who has  elected  under  applicable  Code
provisions  to include  market  discount  in income  annually  as such  discount
accrues will not, however,  be required to treat any gain recognized as ordinary
income or to defer any deductions for interest  expense under these rules.  This
election to include market discount in income currently,  once made,  applies to
all  market  discount  obligations  acquired  on or after  the  first day of the
taxable  year to which the election  applies and may not be revoked  without the
consent of the  Service.  Holders  should  consult  their tax advisors as to the
portion  of any gain that  would be  taxable  as  ordinary  income  under  these
provisions  and any other  consequences  of the market  discount  rules that may
apply to them in particular.

Amortizable Bond Premium

Generally, if the tax basis of an obligation held as a capital asset exceeds the
amount  payable  at  maturity  of the  obligation,  the excess  will  constitute
amortizable  bond  premium  that the holder of such debt  instrument  may elect,
under section 171 of the Code, to amortize as an offset to interest income under
the  constant  yield  method  over the period from its  acquisition  date to the
obligation's maturity date subject to special rules for early call provisions. A
U.S. Holder who elects to amortize bond premium must reduce its tax basis in the
related  7.50% notes by the amount of the  aggregate  amortization  allowable as

                                                          89

<PAGE>



amortizable  bond premium.  An election to amortize bond premium  applies to all
obligations  with  amortizable  bond premium held by the electing U.S. Holder at
the  beginning  of the first  taxable  year to which  the  election  applies  or
thereafter acquired by the U.S. Holder and is irrevocable without the consent of
the Service.


Sale, Retirement, or Other Taxable Disposition

Upon the sale, retirement,  or other taxable disposition of a 7.50% note, a U.S.
Holder will generally recognize gain or loss equal to the difference between (i)
the amount of cash plus the fair market  value of property  received in exchange
for the 7.50% note (except to the extent  attributable  to accrued  interest not
previously taken into account) and (ii) the U.S.  Holder's adjusted tax basis in
the 7.50%  note.  If the 7.50%  note has market  discount  or  amortizable  bond
premium,  appropriate adjustments may be required in computing the U.S. Holder's
adjusted tax basis for the 7.50% note. Any gain or loss on the sale, retirement,
or other taxable  disposition of a 7.50% note, measured as described above, will
generally  be  capital  gain  or  loss  (except  as  discussed   under  "-Market
Discount").  In the case of an individual U.S. Holder, such capital gain will be
taxable at various  preferential rates,  depending on such U.S. Holder's holding
period for the 7.50% note at the time of disposition.

With respect to tax matters related to legal defeasance and covenant  defeasance
in certain circumstances,  see "Description of the 7.50%  Notes-Satisfaction and
Discharge of the Indenture, Defeasance."


Backup Withholding

The  backup  withholding  rules of the Code  require  a payor  to  deduct  and
withhold  a  tax   amount  if

 (1) the  payee   fails  to  furnish  a  taxpayer identification  number ("TIN")
           to the payor,

                                                          90

<PAGE>



     (2) the Service  notifies the payor that the TIN  furnished by the payee is
incorrect,

     (3)   the payee has failed to report  properly the receipt of a "reportable
           payment" and the Service has notified the payor that  withholding  is
           required, or

     (4)   there has been a failure  on the part of the payee to  certify  under
           penalty of perjury that the payee is not subject to withholding under
           section 3406 of the Code.

If any one of the events  discussed  above occurs,  Qwest or its paying agent or
other  withholding  agent will be required to withhold a tax equal to 31 percent
of any  "reportable  payment"  which  includes,  among  other  things,  interest
actually paid and amounts paid through brokers in retirement of securities.  Any
amount  withheld  from a payment to a U.S.  Holder under the backup  withholding
rules will be allowed as a refund or credit  against  the U.S.  Holder's  United
States federal income tax,  provided that the required  information is furnished
to the Service. Certain U.S. Holders (including, among others, corporations) are
not subject to the backup withholding or information reporting requirements.

Certain Tax Consequences to Non-U.S. Holders

General.  The following  discussion is for general information purposes only and
does not cover all aspects of United States federal taxation that may
apply to, or the actual tax effect  that any of the  matters  described  in this
discussion will have on, any particular Non-U.S.  Holder.  Non-U.S.  Holders are
urged to consult their tax advisors as to the  particular  tax  consequences  to
them of purchasing, holding, and disposing of the 7.50% notes.

Portfolio Interest Exemption. A Non-U.S. Holder not engaged in any U.S. trade or
business will generally, under the portfolio interest exemption of the Code, not
be  subject to United  States  federal  income  taxes or United  States  federal
withholding  tax, on payments of principal and interest paid on the 7.50% notes,
provided that

     (1)   the  Non-U.S.  Holder  does not  actually  or  constructively  own 10
           percent or more of the total combined  voting power of all classes of
           stock of Qwest entitled to vote,

     (2) the Non-U.S. Holder is not

        (a)      a bank receiving  interest pursuant to a loan agreement entered
                 into in the ordinary course of its trade or business or

        (b) a controlled  foreign  corporation  that is related to Qwest through
                 stock ownership,

     (3)   such interest is not effectively connected with a United States trade
           or business and

     (4) either

           (a)   the beneficial  owner of the 7.50% notes  certifies to Qwest or
                 its agent,  under  penalties of perjury,  that it is not a U.S.
                 Holder and provides a completed IRS Form W-8  ("Certificate  of
                 Foreign Status") or

           (b)   a securities  clearing  organization,  bank, or other financial
                 institution  which holds customers'  securities in the ordinary
                 course of its trade or business (a "financial institution") and
                 which holds the 7.50%  notes,  certifies to Qwest or its agent,
                 under penalties of perjury,  that it has received Form W-8 from
                 the  beneficial  owner  or that it has  received  from  another
                 financial institution a Form W-8 and furnishes the payor with a
                 copy of the  Form  W-8 and none of the  persons  reviewing  the
                 relevant  certification  or IRS form has actual  knowledge that
                 the certification or any statement on the IRS form is false.

If any of the  situations  described  in  proviso  (i),  (ii),  or  (iv)  of the
preceding  sentence does not exist,  interest on the 7.50% notes,  when paid, is
subject to United States  withholding  tax at the rate of 30 percent,  unless an
income  tax  treaty  between  the  United  States  and the  country of which the
Non-U.S.  Holder is a tax resident  provides for the elimination or reduction in
the rate of United States  federal  withholding  tax.  Interest for this purpose
includes income, other than capital gains, received from the sale or exchange of
the 7.50%  notes or from a payment  on the 7.50%  notes to the  extent of unpaid
interest  accrued  while the 7.50% notes were held by a Non-U.S.  Holder and the
amounts so accrued were not previously subject to United States withholding tax.


                                                          91

<PAGE>



Effectively  Connected  Income.  If a  Non-U.S.  Holder is engaged in a trade or
business in the United  States and  interest  on the 7.50% notes is  effectively
connected  with the conduct of such trade or  business,  such  Non-U.S.  Holder,
although  exempt from United States federal  withholding tax as discussed in the
preceding  paragraph  (or by reason of the delivery of a properly  completed IRS
Form 4224), will be subject to United States federal income tax on such interest
and on any gain realized on the sale, exchange,  or other disposition of a 7.50%
note  in the  same  manner  as if it were a U.S.  Holder.  In  addition,  if the
Non-U.S. Holder is a foreign corporation,  it may be subject to a branch profits
tax equal to 30 percent of its  effectively  connected  earnings and profits for
that taxable  year,  subject to certain  adjustments,  unless it qualifies for a
lower rate under an applicable income tax treaty.

Federal  Estate Tax.  7.50% notes owned or treated as owned by an individual who
is neither a United States citizen nor a United States  resident (as defined for
United States federal estate tax purposes) at the time of death will be excluded
from the individual's gross estate for United States federal estate tax purposes
and will not be subject to United States  federal  estate tax if the  individual
does not own,  actually  or  constructively,  10% or more of the total  combined
voting power of all classes of stock of Qwest  entitled to vote and, at the time
of such individual's death,  payments with respect to such 7.50% notes would not
have been effectively  connected to the conduct by such individual of a trade or
business in the United States.

Disposition of the 7.50% Notes. A Non-U.S.  Holder generally will not be subject
to United States federal income tax on any gain realized in connection  with the
sale, exchange, or retirement of the 7.50% notes, unless:

(1) (a) the gain is effectively connected with a trade or business carried on by
                  the Non-U.S. Holder within the United States or

   (b) if a tax treaty applies, the gain is generally attributable to the United
              States permanent establishment maintained by the Non-U.S.  Holder,

     (2)   in the case of a Non-U.S. Holder who is an individual,  such Non-U.S.
           Holder is present  in the  United  States for 183 days or more in the
           taxable  year  of  disposition,  and  certain  other  conditions  are
           satisfied, or

     (3)   the Non-U.S.  Holder is subject to tax pursuant to  provisions of the
           Code applicable to United States expatriates.

Information Reporting and Backup Withholding Tax. In general, there is no United
States information  reporting  requirement or backup withholding tax on payments
to Non-U.S.  Holders who provide the appropriate  certification  described above
regarding  qualification for the portfolio interest exemption from United States
federal income tax for payments of interest on the 7.50% notes.

In general,  backup  withholding and  information  reporting will not apply to a
payment of the gross proceeds of a sale of the 7.50% notes effected at a foreign
office of a broker.  If,  however,  such  broker is, for United  States  federal
income tax purposes, a United States person, a controlled foreign corporation, a
foreign person 50% or more of whose gross income for certain  periods is derived
from activities  that are  effectively  connected with the conduct of a trade or
business in the United  States,  or (in the case of payments made after December
31, 1999) a foreign  partnership with certain  connections to the United States,
such payments will not be subject to backup withholding, but will be subject  to
information  reporting,  unless:

                                                          92

<PAGE>





     (1)   such  broker  has  documentary  evidence  in  its  records  that  the
           beneficial  owner is a Non-U.S.  Holder and certain other  conditions
           are met or

     (2) the beneficial owner otherwise establishes an exemption.

Payment by Qwest of principal  on the 7.50% notes or payment by a United  States
office of a broker of the  proceeds  of a sale of the 7.50%  notes is subject to
both backup  withholding and information  reporting  unless the beneficial owner
provides a completed  IRS Form W-8 which  certifies  under  penalties of perjury
that it is a Non-U.S.  Holder who meets all the  requirements for exemption from
United  States  federal  income  tax on any gain  from the  sale,  exchange,  or
retirement of the 7.50% notes.  Backup withholding is not an additional tax. Any
amounts withheld under the backup  withholding rules will be allowed as a refund
or a credit  against such Non-U.S.  Holder's  United States  federal  income tax
liability, provided the required information is furnished to the Service.

Recently  promulgated  Regulations  (the "New  Regulations")  would  modify  the
procedures  to be followed by Non-U.S.  Persons and payors of interest  and sale
proceeds  in  complying  with the  United  States  federal  withholding,  backup
withholding,  and  information  reporting  rules,  and the  availability  of any
exemption therefrom.  The New Regulations are not currently effective,  but will
generally be effective  for payments  made after  December 31, 1999. In general,
the  New  Regulations  do  not  significantly   alter  the  current  substantive
withholding  and  information  requirements,  but  unify  current  certification
procedures and forms and clarify reliance standards.  The New Regulations impose
more stringent conditions on the ability of financial  intermediaries acting for
Non-U.S. Holders to provide certifications on behalf of Non-U.S. Holders. Each
Holder of a 7.50% note is strongly  urged to consult  its tax advisor  regarding
the effect of the New Regulations on the purchase, ownership, and disposition of
the 7.50% notes.
    

                             PLAN OF DISTRIBUTION
   
Each broker-dealer that receives new 7.50% notes for its own account pursuant to
the  exchange  offer  must  acknowledge  that it will  deliver a  prospectus  in
connection with any resale of the new 7.50% notes. A broker-dealer  may use this
prospectus,  as it may be  amended  or  supplemented  from  time to time,  by in
connection  with  resales of new 7.50% notes  received in exchange for old 7.50%
notes  where such old 7.50%  notes were  acquired  as a result of  market-making
activities or other trading activities. The Company has agreed that for a period
of one year after closing of the exchange offer,  it will make this  prospectus,
as amended or supplemented, available to any broker-dealer for use in connection
with any such resale.

The Company  will not receive any  proceeds  from any sale of new 7.50% notes by
any  broker-dealer.  New 7.50% notes  received by  broker-dealers  for their own
account  pursuant to the Exchange  Offer may be sold from time to time in one or
more transactions in the  over-the-counter  market, in negotiated  transactions,
through the writing of options on the new 7.50% notes or a  combination  of such
methods of resale,  at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any resale may be
made directly to purchasers or to or through  brokers or dealers who may receive
compensation   in  the  form  of  commissions  or  concessions   from  any  such
broker-dealer   and/or  the  purchasers  of  any  such  new  7.50%  notes.   Any
broker-dealer  that resells new 7.50% notes that were received by it for its own
account  pursuant  to the  eExchange  oOffer  and  any  broker  or  dealer  that
participates in a distribution

                                                          93

<PAGE>



of such new 7.50% notes may be deemed to be an "underwriter"  within the meaning
of the  Securities  Act and any profit on any such resale of new 7.50% notes and
any commissions or concessions  received by any such persons may be deemed to be
underwriting  compensation  under the Securities  Act. The letter of transmittal
states  that  by  acknowledging  that  it  will  deliver  and  by  delivering  a
prospectus,  a  broker-dealer  will  not  be  deemed  to  admit  that  it  is an
"underwriter" within the meaning of the Securities Act.

For a period of one year after closing of the exchange  offer,  the Company will
promptly  send  additional  copies  of  this  prospectus  and any  amendment  or
supplement to this prospectus to any broker-dealer  that requests such documents
in the  letter of  transmittal.  The  Company  has  agreed  to pay all  expenses
incident to the Company's  performance of, or compliance  with, the Registration
Agreement  and all  expenses  incident  to the  exchange  offer  (including  the
expenses  of one  counsel  for the  holders of the old 7.50%  notes)  other than
commissions  or  concessions  of any brokers or dealers,  and will indemnify the
holders  (including  any  broker-dealers)  and  certain  parties  related to the
holders against certain liabilities,  including liabilities under the Securities
Act.

  The Company has not entered into any arrangements or  understandings  with any
person to distribute the new 7.50% notes to be received in the exchange offer.

                       INFORMATION NOT REQUIRED IN PROSPECTUS

   ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

  Section  145 of the  Delaware  General  Corporation  Law  ("DGCL")  empowers a
Delaware  corporation  to indemnify any persons who are, or are threatened to be
made,  parties  to  any  threatened,   pending  or  completed  action,  suit  or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the  right of such  corporation),  by reason of the fact that
such person is or was an officer or director of such  corporation,  or is or was
serving at the request of such corporation as a director,  officer,  employee or
agent  of  another  corporation,  partnership,  joint  venture,  trust  or other
enterprise.  The indemnity may include  expenses  (including  attorneys'  fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in  connection  with such  action,  suit or  proceeding,  if such
officer or director  acted in good faith and in a manner such person  reasonably
believed to be in or not opposed to the best interests of the corporation,  and,
with respect to any criminal  action or proceeding,  had no reasonable  cause to
believe  such  officer's  or  director's   conduct  was  unlawful.   A  Delaware
corporation may indemnify officers and directors in an action by or in the right
of the corporation under the same conditions,  except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the  corporation in the  performance of his duty.  Where an officer or
director is  successful  on the merits or otherwise in the defense of any action
referred to above,  the  corporation  must  indemnify  such  officer or director
against the  expenses  which such officer or director  actually  and  reasonably
incurred.

  In accordance with Section 102(b)(7) of the DGCL, the Company's Certificate of
Incorporation  provides  that  directors  shall  not be  personally  liable  for
monetary  damages for breaches of their  fiduciary duty as directors  except for
(i) breaches of their duty of loyalty to the Company or its  stockholders,  (ii)
acts or omissions not in good faith or which involve  intentional  misconduct or
knowing  violations of law, (iii) certain  transactions under Section 174 of the
DGLC (unlawful  payment of dividends or unlawful stock purchases or redemptions)
or (iv) transactions from which a director derives an improper personal benefit.
The effect of this provision is to eliminate the personal liability of directors
for monetary  damages for actions  involving a breach of their fiduciary duty of
care, including any actions involving gross negligence.

  The  Certificate of  Incorporation  and the By-laws of the Company provide for
indemnification  of the Company's  officers and directors to the fullest  extent
permitted by applicable law, except that the By-laws provide that the Company is
required to  indemnify  an officer or director in  connection  with a proceeding
initiated by such person only if the  proceeding  was authorized by the Board of
Directors of the Company. In addition,  the Company maintains insurance policies
which  provide  coverage for its officers  and  directors in certain  situations
where the Company cannot directly indemnify such officers or directors.

                                                         100

  Pursuant to Section 145 of the DGCL and the Certificate of  Incorporation  and
the By-laws of the  Company,  the Company  maintains  directors'  and  officers'
liability insurance coverage.

     (b)  Financial  Statement  Schedules.  The  following is a complete list of
financial  statement  schedules  filed as part of this  Registration  Statement,
which are  incorporated by reference herein from Amendment No. 1 to Registration
Statement on Form S-4 (File No. 333-65095):

Schedule Number

   ITEM 22. UNDERTAKINGS.

     (a) The undersigned Company hereby undertakes:

       (1) That  prior to any public  reoffering  of the  securities  registered
hereunder  through  use of a  prospectus  which  is a part of this  registration
statement,  by any person or party who is deemed to be an underwriter within the
meaning  of Rule  145(c)  under the  Securities  Act of 1933,  as  amended  (the
"Securities  Act"), the issuer  undertakes that such reoffering  prospectus will
contain the  information  called for by the  applicable  registration  form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

       (2) That every  prospectus  (i) that is filed  pursuant to paragraph  (1)
immediately preceding, or (ii) that purports to meet the requirements of section
10(a)(3) of the  Securities  Act and is used in  connection  with an offering of
securities subject to Rule 415 under the Securities Act, will be filed as a part
of an amendment to the  registration  statement  and will not be used until such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities Act, each such post-effective  amendment shall be deemed to
be a new registration  statement relating to the securities offered therein, and
the offering of such  securities  at that time shall be deemed to be the initial
bona fide offering thereof.

     (b) Insofar as indemnification for liabilities arising under the Securities
  Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Commission such  indemnification  is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  registrant  in the
successful defense of any action, suit or proceedings) is

                                                         107

<PAGE>



asserted by such director,  officer or controlling person in connection with the
securities being  registered,  the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court
of  appropriate  jurisdiction  the  question  whether  indemnification  by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     (c) The  undersigned  Company hereby  undertakes to respond to requests for
information  that is incorporated  by reference into the prospectus  pursuant to
Items 4, 10(b),  11 or 13 of this Form,  within one  business  day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     (d) The  undersigned  Company  hereby  undertakes  to  supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

    (e)  The  undersigned  Company  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new registration statement
  relating  to  the  securities  offered  therein,  and  the  offering  of  such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

    (f) The undersigned Company hereby undertakes:

      (1) To file,  during any period in which offers or sales are being made, a
 post-effective amendment to this registration statement:

        (i) to include any prospectus required by Section 10(a)(3) of the
Securities Act;

        (ii) to reflect in the  prospectus any facts or events arising after the
  effective date of the registration statement (or the most recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement.  Notwithstanding the foregoing, any increase or decrease in volume of
securities  offered (if the total dollar value of  securities  offered would not
exceed that which was  registered) and any deviation from the low or high end of
the estimated  maximum offering range may be reflected in the form of Prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20 percent  change in the
maximum aggregate

                                                         108

offering price set forth in the "Calculation of Registration Fee" table in
the effective registration statement; and

        (iii) to include any  material  information  with respect to the plan of
distribution  not  previously  disclosed  in the  registration  statement or any
material change to such information in the registration statement.

      (2)  That,  for  the  purpose  of  determining  any  liability  under  the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment any
  of the securities being registered which remain unsold at the termination of
the offering.

      (4) For purposes of determining  any liability  under the Securities  Act,
the  information  omitted  from  the  form  of  prospectus  filed  as  part of a
registration  statement in reliance  upon Rule 430A and contained in the form of
prospectus  filed by the  Company  pursuant to Rule  424(b)(1)  or (4) or 497(h)
under the Securities Act shall be deemed part of the  registration  statement as
of the time it was declared effective.
