PROSPECTUS

                       OFFER TO EXCHANGE ALL OUTSTANDING
                            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 ("Old  Notes") for
our registered 7.50% Series B Senior Notes due 2008 ("New Notes"). We issued the
Old Notes on November 4, 1998 and a total principal  amount of $750.0 million is
outstanding.  The terms of the New Notes are  identical  to the terms of the Old
Notes except that the New Notes are registered under the Securities Act of 1933,
as amended,  and will not contain any legends  restricting  their  transfer.  We
sometimes  collectively  refer to the New Notes and the Old Notes as the  "7.50%
Notes."

                       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 annum.

- -    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 25 of this
     Prospectus.
   
- -    Our offer to exchange Old Notes for New 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 Notes
     beginning on page of this Prospectus.
                                                  
- -    The 7.50% Notes are senior  unsecured  obligations and are of equal ranking
     in right of payment to our existing  future  senior debt and rank senior in
     right of payment to our existing and future  subordinated  debt.  Please be
     advised that,  as of September 30, 1998, we had $1,301.2  million of senior
     debt of equal ranking in right of payment to the 7.50% Notes and

- -    If  you  fail  to  tender  your  Old  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  Notes  on any  securities  exchange  and,
therefore, no active public market is anticipated.

                           FORWARD-LOOKING STATEMENTS


                                                          6





This Prospectus  contains or incorporates by reference certain  "forward-looking
statements"  as that term is used in Section 27A of the  Securities Act of 1933,
as amended (the "Securities  Act") and Section 21E of the Exchange Act 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

- - 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 such statements are subject to risks and  uncertainties,  actual results
may differ  materially  from those  expressed or implied by the  forward-looking

                               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 Notes and the exchange offer.
Qwest  Communications  International  Inc.  is  sometimes  referred  to 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.

                                                          9





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.

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.
Subsequent to this, the Company obtained other financing through the issuance of
$300.0  million of 7.25% Senior Notes due 2008 (the "7.25% Notes Due 2008"),  as
discussed  below,  and through an investment in the Company of $200.0 million by
Microsoft  Corporation.  As a result of entering  into these  transactions,  the
closing of the credit facility was postponed. We are currently in the process

                                                          10





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  the  execution  of  a  mutually  satisfactory  credit
agreement.  We are working with the  syndicate  of banks  toward  closing in the
first quarter of 1999.

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 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 ("10 7/8% Notes"). 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  Notes  to the  initial  purchaser  in a  transaction  exempt  from the
     registration  requirements  of the  Securities Act of 1933, as amended (the
     "Securities  Act").  The  terms  of the New  Notes  and the Old  Notes  are
     substantially identical in all material respects, except that the New Notes
     will be freely  transferable  by the holders  thereof  except as  otherwise
     provided in this Prospectus. See "Description of the 7.50% Notes."

THE EXCHANGE OFFER...........               

     $1,000  principal amount of New Notes in exchange for each $1,000 principal
     amount  of  Old  Notes.  As of the  date  of  this  Prospectus,  Old  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 Notes issued  pursuant to the exchange  offer in exchange
     for Old Notes may be offered for resale, resold or otherwise transferred by
     holders  thereof  (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 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 such
     New Notes are acquired in the ordinary course of such holders' business and
     such  holders  have  no  arrangement   with  any  person  to  engage  in  a
     distribution of New 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 the exchange
     offer as in such other circumstances.  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  such  New  Notes  and  has no
     arrangement or understanding to participate in a distribution of New Notes.
     Each  broker-dealer that receives New 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 such New Notes.  Broker-dealers  who acquired Old 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 Notes.

REGISTRATION RIGHTS
  AGREEMENT..................               

     We sold the Old  Notes on  November  4,  1998,  in a private  placement  in
     reliance on Section 4(2) of

                                                          12





     the Securities  Act. The Old Notes were  immediately  resold by the initial
     purchaser in reliance on Rule 144A promulgated under the Securities Act. In
     connection with the sale, we entered into a Registration  Rights  Agreement
     with the initial purchaser (the "Registration Rights Agreement")  requiring
     us to make the exchange offer.  The Registration  Rights Agreement  further
     provides  that we must use our  reasonable  best  efforts  to (i) cause the
     Registration  Statement  with respect to the exchange  offer to be declared
     effective  within 150 days of the date on which we issued the Old Notes and
     (ii) consummate the exchange offer on or before the 180th day following the
     date on which we issued the Old 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
     such later date and time to which it is extended.

WITHDRAWAL...................               

     The tender of the Old 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 such
     later  date and time to  which we  extend  the  offer.  Any Old  Notes  not
     accepted for exchange  for any reason will be returned  without  expense to
     the tendering holder thereof as soon as practicable after the expiration or
     termination of the exchange offer.

INTEREST ON THE NEW NOTES AND
  THE OLD NOTES..............               

     Interest  on the New  Notes  will  accrue  from  the  date of the  original
     issuance of the Old Notes or from the date of the last periodic  payment of
     interest on the Old Notes,  whichever is later. No additional interest will
     be paid on Old Notes tendered and accepted for exchange.

CONDITIONS TO THE EXCHANGE
  OFFER......................               

     The exchange offer is subject to certain customary  conditions,  certain of
     which may be waived by us. See "The Exchange Offer -- Certain Conditions to
     Exchange Offer."

PROCEDURES FOR TENDERING OLD
  NOTES......................               

     Each  holder of the Old Notes  wishing  to accept the  exchange  offer must
     complete,  sign and date the letter of transmittal,  or a copy thereof,  in
     accordance  with the  instructions  contained in this Prospectus and in the
     letter of transmittal, and

                                                          13





     mail or otherwise deliver the letter of transmittal,  or the copy, together
     with the Old Notes and any other  required  documentation,  to the exchange
     agent at the address set forth in this Prospectus.  Persons holding the Old
     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  Notes  acquired  pursuant  to the  exchange  offer  are  being
     obtained in the ordinary  course of business of the person  receiving  such
     New Notes,  whether or not such person is the registered  holder of the Old
     Notes,  (ii) the holder is not engaging in and does not intend to engage in
     a  distribution  of such  New  Notes,  (iii)  the  holder  does not have an
     arrangement  or  understanding  with  any  person  to  participate  in  the
     distribution of such New Notes,  and (iv) the holder is not an "affiliate,"
     as defined  under Rule 405  promulgated  under the  Securities  Act, of the
     Company.

     We will  accept  for  exchange  any and all Old 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 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 (the "Exchange Agent") in
     connection with the exchange offer.

FEDERAL INCOME TAX
  CONSIDERATIONS.............               

     In the  opinion of our  counsel,  the  exchange  of Old Notes for New Notes
     pursuant to the exchange offer should not constitute a taxable exchange for
     United  States  federal  income tax  purposes.  See "Certain  United States
     Federal Income Tax Considerations."

EFFECT OF NOT TENDERING......               

     Old 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  thereof.  We will have no further
     obligation to

                                                          14





     provide for the registration under the Securities Act of such Old Notes.

THE NEW NOTES

The summary below describes the principal terms of the New 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 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 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 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.
     ("Icon"),  the redemption of $87.5 million of 10 7/8% Notes,  the repayment
     of $57.3 million of our equipment credit facility,  the offering of the Old
     Notes,  the offering of our 7.25%  Senior Notes Due 2008 ("7.25%  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 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 we and our creditors,  including the
     holders  of  New  Notes,  to  participate  in  the  assets  of  any  of our
     subsidiaries  upon any liquidation or reorganization of any such subsidiary
     will be

                                                          15





     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 the Company  occurs (as defined),  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  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 such  agreements  would require such  application 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

                                                          16





     fully  described under  "Description of the 7.50% Notes"  beginning on page
     47.

     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 such 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..............               

     The Company will not receive any cash proceeds from the issuance of the New
     Notes pursuant to this Prospectus.


RISK FACTORS

We urge you to  carefully  review  the Risk  Factors  beginning  on page 25for a
discussion of factors you should consider  before  exchanging your Old Notes for
New Notes.


                                                          17





                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 Qwest 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 Qwest's
acquisition of EUnet  International  Ltd. and the joint venture with KPN Telecom
B.V.  because such  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
such 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 such 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.

Qwest has  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  Qwest's
consideration  of the study's  preliminary  findings as of this date,  Qwest has
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,  Qwest acquired LCI. The acquisition was accounted for
         as a purchase and the results of LCI's  operations  are  included  with
         Qwest's for the period subsequent to the acquisition.

(2)      In November 1993, Qwest sold  substantially all of its then owned fiber
         optic  network   capacity  and  related   equipment  and  assets  to  a
         third-party  purchaser for $185.0 million (the "1993  Capacity  Sale").
         After  deducting the carrying value of the assets sold and direct costs
         associated  with the 1993  Capacity  Sale,  Qwest  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  Qwest  will use to  provide  cash for the
         construction cost of the Qwest 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 Qwest's operating
         performance  or  as  an  alternative  to  cash  flows  as a  source  of
         liquidity,

                                                          21





         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)      Qwest has not declared or paid cash dividends on the Qwest common stock
         since becoming a public company in June 1997.

                                 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 Notes  who do not  exchange  their Old Notes for New Notes  will
continue to be subject to the  restrictions  on transfer of the Old Notes as set
forth in the  legends on the Old  Notes.  In  general,  the Old 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 10 7/8%  Notes,  the  repayment  of $57.3  million  of our
equipment  credit  facility,  the  offering  of the 7.25%  Notes  Due 2008,  the
offering of the Old 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.


                                                          23





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 10 7/8% Notes,  the repayment of $57.3 million of
our equipment  credit  facility,  the offering of the Old Notes, the offering of
the 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  such assets in a  communications  business.  These  assets are highly
specialized   and,  taken   individually,   can  be  expected  to  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 10 7/8% Notes,  the repayment of $57.3 million of
our equipment  credit  facility,  the offering of the Old Notes, the offering of
the 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.
Subsequent to this, the Company obtained other financing through the issuance of
$300.0  million of 7.25% Senior Notes due 2008 and through an  investment in the
Company of $200.0 million by Microsoft Corporation. As a result of entering into
these  transactions,  the closing of the credit  facility was postponed.  We are
currently in the process of obtaining a new unsecured $750.0 million to

                                                          24





$1.0 billion credit  facility  through a syndicate of banks.  Closing of the new
credit  facility is  conditioned,  among other  things,  on the  execution  of a
mutually  satisfactory  credit  agreement.  We are working with the syndicate of
banks toward closing in the first quarter of 1999.

  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 such 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 such 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

                                                          25





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 the Senior Note Indentures and
our senior  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  such  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 the Qwest 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

                                                          26





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
(the  "Telecommunications   Act")  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 (the "Regional
Bell  Operating  Companies")  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

                                                          27





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 such 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

                                                        28





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,
such systems will not recognize  the  difference in a year that begins with "20"
rather than "19." As a result of the date change in the year 2000, if any of 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

                                                          29





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 such 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 such systems for year 2000 compliance; (iii) modify, upgrade or
replace  non-compliant  systems; (iv) test the corrected systems; and (v) deploy
the corrected systems.

  The year 2000 compliance  group has focused mainly on 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

                                                          30





$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.

                                                          31





  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 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 Old  Notes  were  originally  issued  and sold 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  Notes may not be  reoffered,  resold or
otherwise  pledged,  hypothecated  or 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 Old Notes,  the  Company  and the  initial
purchaser  of the Old  Notes  entered  into  the  Registration  Agreement  as of
November 4, 1998.  Pursuant to 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 Notes by February 2, 1999;  (ii) use its
best efforts to cause such Registration Statement to be declared effective under
the Securities  Act by March 3, 1999;  and (iii)  consummate an offer of the New
Notes in exchange for surrender of the Old Notes by April 2, 1999. A copy of the
Registration  Agreement  has  been  filed  as an  exhibit  to  the  Registration
Statement of which this  Prospectus  is a part.  The  Registration  Statement of
which this  Prospectus is a part is intended to satisfy certain of the Company's
obligations under the Registration Agreement and the Purchase Agreement.

RESALE OF THE NEW NOTES

  Based upon  no-action  letters  issued by the staff of the Commission to third
parties, the Company believes that the New Notes issued pursuant to the Exchange
Offer in exchange  for Old Notes would in general be freely  transferable  after
the Exchange Offer without further  registration under the Securities Act if the
holder of the New 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 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 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
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 Notes wishing to accept the Exchange  Offer must represent to the
Company that such conditions have been met. Each broker-dealer that receives New
Notes for its own account pursuant to the Exchange Offer,  where it acquired the
Old  Notes  exchanged  for such New  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 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

                                                          33





supplemented  from time to time,  may be used by a  broker-dealer  in connection
with  resales of New Notes  received  in  exchange  for Old Notes where such Old
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  consummation  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 "Plan of Distribution."

TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES

  Upon the terms and subject to the conditions set forth in this  Prospectus and
in the  accompanying  Letter  of  Transmittal  (which  together  constitute  the
Exchange  Offer),  the Company  will accept for  exchange  any and all Old 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  Notes in  exchange  for each  $1,000  principal  amount at  maturity  of
outstanding Old Notes surrendered  pursuant to the Exchange Offer. Old Notes may
be tendered only in integral multiples of $1,000.

  The form and  terms of the New Notes are the same as the form and terms of the
Old Notes except that (i) the exchange will be registered  under the  Securities
Act and hence the New 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 Notes will not be  entitled  to certain  rights of holders of
Old Notes under the  Registration  Agreement,  which  rights with respect to Old
Notes will terminate upon the  consummation of the Exchange Offer. The New Notes
will  evidence the same debt as the Old 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 Notes is outstanding.  This  Prospectus,  together
with the Letter of  Transmittal,  is first  being sent on or about  January  __,
1999, to all holders of Old Notes known to the Company.

  Holders of the Old 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 Securities  Act, the Exchange
Act and the rules and regulations of the Commission thereunder. 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 Notes, by giving written notice of such
extension to the holders thereof as described below.  During any such extension,
all Old Notes previously tendered will remain subject to the Exchange Offer and

                                                          34





may be accepted  for  exchange by the  Company.  Any Old Notes not  accepted for
exchange for any reason will be returned without expense to the tendering holder
thereof as promptly as practicable after the expiration of the Exchange Offer.

  The Company  expressly  reserves the right to amend or terminate  the Exchange
Offer  upon  the  occurrence  of any of the  conditions  of the  Exchange  Offer
specified below under "--Certain  Conditions of the Exchange Offer." The Company
will  give  written  notice  of  any  extension,  amendment,   nonacceptance  or
termination  to the holders of the Old Notes as promptly  as  practicable,  such
notice in the case of any  extension to be issued by means of a press release or
other public  announcement  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 NOTES

  The tender to the Company of Old Notes by a holder  thereof as set forth below
and the acceptance  thereof by the Company will  constitute 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 Notes
for exchange  pursuant to the Exchange Offer must transmit a properly  completed
and duly executed Letter of Transmittal,  including all other documents required
by such Letter of Transmittal, to the Exchange Agent at one of the addresses set
forth below under  "--Exchange  Agent" on or prior to the  Expiration  Date.  In
addition,  either (i)  certificates  for such Old 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 such Old Notes,  if such 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 prior to the
Expiration  Date, or (iii) the holder must comply with the  guaranteed  delivery
procedures described below.

  THE METHOD OF  DELIVERY  OF OLD NOTES,  LETTERS OF  TRANSMITTAL  AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS.  IF SUCH 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 NOTES SHOULD
BE SENT TO THE COMPANY.

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

                                                          35





a person or persons  other than the  registered  holder or holders of Old Notes,
such Old  Notes  must be  endorsed  or  accompanied  by  appropriate  powers  of
attorney,  in either case signed  exactly as the name or names of the registered
holder or holders that appear on the Old Notes.

  Signatures on a Letter of Transmittal  or a notice of withdrawal,  as the case
may be,  must be  guaranteed  unless  the Old  Notes  surrendered  for  exchange
pursuant  thereto are tendered  (i) by a registered  holder of the Old 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 herein below). In the event that signatures
on a Letter of Transmittal  or a notice of  withdrawal,  as the case may be, are
required to be guaranteed,  such  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 Notes are registered in the name of a person other than a
signer of the Letter of Transmittal, the Old 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,  duly  executed by the  registered  holder with the  signature
thereon guaranteed by an Eligible Institution.

  All  questions  as to the  validity,  form,  eligibility  (including  time  of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the  Company  in its sole  discretion,  which  determination  shall be final and
binding.  The Company  reserves the absolute right to reject any and all tenders
of any  particular  Old  Notes  not  properly  tendered  or not  to  accept  any
particular Old 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 Notes either before or after the Expiration  Date  (including the
right to waive the  ineligibility of any holder who seeks to tender Old Notes in
the Exchange  Offer).  The  interpretation  of the terms and  conditions  of the
Exchange  Offer as to any  particular  Old  Notes  either  before  or after  the
Expiration  Date  (including  the  Letter of  Transmittal  and the  instructions
thereto)  by the  Company  shall be final and  binding  on all  parties.  Unless
waived,  any defects or  irregularities  in connection with tenders of Old Notes
for exchange must be cured within such 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 Notes for exchange, nor shall any of them incur any
liability for failure to give such notification.

  If the Letter of Transmittal or any Old 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, such
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.


                                                          36





  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 Notes in the ordinary  course of
its business and (iii) at the time of the  consummation 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 Notes. If the
holder is a  broker-dealer  that will  receive  New Notes for its own account in
exchange  for  Old  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 such New 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 NOTES FOR EXCHANGE; DELIVERY OF NEW 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 Notes
properly  tendered and will issue the New Notes promptly after acceptance of the
Old 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 Notes for exchange  when,  as and if the Company has given oral or
written notice thereof to the Exchange Agent,  with written  confirmation of any
oral notice to be given promptly thereafter.

  The New Notes will bear interest at the same rate and on the same terms as the
Old Notes. Consequently, cash interest on the New 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 Note will accrue from the last interest  payment date on which interest
was paid on the  surrendered  Old Note or, if no interest  has been paid on such
Old Note,  from the date on which cash  interest on such Old Note would begin to
accrue. Consequently,  holders whose Old Notes are accepted for exchange will be
deemed to have waived the right to receive  any  accrued but unpaid  interest on
the Old Notes.

  In all cases,  the  issuance of New Notes for Old 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 such Old Notes or a timely  Book-Entry
Confirmation  of such  Old  Notes  into  the  Exchange  Agent's  account  at the
Book-Entry  Transfer Facility,  a properly completed and duly executed Letter of
Transmittal and all other required documents.  If any tendered Old Notes are not
accepted  for any reason set forth in the terms and  conditions  of the Exchange
Offer,  or if Old  Notes are  submitted  for a greater  amount  than the  holder
desires to exchange, such unaccepted or non-exchanged Old Notes will be returned
without  expense to the tendering  holder  thereof (or, in the case of Old Notes
tendered by book-entry  procedures described below, such non exchanged Old Notes
will be credited to an account maintained with such Book-Entry Transfer

                                                          37





Facility)  designated by the tendering  holder as promptly as practicable  after
the expiration or termination of the Exchange Offer.

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 Notes in exchange for, any Old
Notes and may terminate or amend the Exchange Offer as provided  herein prior to
the  Expiration   Date,  if  because  of  any  changes  in  law,  or  applicable
interpretations  thereof 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.  Such 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 with respect to
the Old Notes at the Book-Entry  Transfer  Facility for purposes of 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 Notes by causing the
Book-Entry  Transfer  Facility  to  transfer  such Old Notes  into the  Exchange
Agent's  account at the  Book-Entry  Transfer  Facility in accordance  with such
Book-Entry  Transfer  Facility's  procedures  for  transfer.  However,  although
delivery of Old Notes may be effected through  book-entry  transfer at the Book-
Entry Transfer Facility,  the Letter of Transmittal or facsimile thereof,  or an
Agent's Message,  with any required signature  guarantees and any other required
documents,  must,  in any case, be  transmitted  to and received by the Exchange
Agent at one of the  addresses  set forth below under  "--Exchange  Agent" on or
prior to 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,  which acknowledgment states that such participant has received and
agrees  to be  bound  by the  terms  of  the  Letter  of  Transmittal,  and  the
Corporation may enforce the Letter of Transmittal against such participant.

GUARANTEED DELIVERY PROCEDURES

  If a registered  holder of the Old Notes  desires to tender such Old Notes and
the Old Notes  are not  immediately  available,  or time  will not  permit  such
holder's  Old 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 a timely basis, a tender may be effected if (i) the tender is made

                                                        38





through an Eligible Institution, (ii) prior to the Expiration Date, the Exchange
Agent has received from such Eligible  Institution a properly completed and duly
executed Letter of Transmittal (or a facsimile thereof) and Notice of Guaranteed
Delivery, substantially 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 Notes and the amount of Old Notes, stating that
the tender is being made thereby and guaranteeing  that within five trading days
(on the Nasdaq Stock Market's  National Market (the "Nasdaq  National  Market"))
after  the  date  of  execution  of  the  Notice  of  Guaranteed  Delivery,  the
certificates for all physically tendered Old Notes, in proper form for transfer,
or a  Book-Entry  Confirmation,  as the case  may be,  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 Notes,  in proper form for  transfer,  or a Book-Entry
Confirmation, as the case may be, 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  execution  of the Notice of  Guaranteed
Delivery.

WITHDRAWAL RIGHTS

  Tenders  of Old 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 such notice of withdrawal  must specify the name of the
person having tendered the Old Notes to be withdrawn,  identify the Old Notes to
be withdrawn  (including the amount of such Old Notes), and (where  certificates
for Old Notes have been  transmitted)  specify  the name in which such Old Notes
are  registered,   if  different  from  that  of  the  withdrawing   holder.  If
certificates  for Old Notes have been  delivered or otherwise  identified to the
Exchange Agent,  then, prior to the release of such 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 such holder is an Eligible Institution. If Old 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 Notes
and otherwise  comply with the procedures of such facility.  All questions as to
the validity,  form and eligibility  (including time of receipt) of such notices
will be determined by the Company whose determination shall be final and binding
on all  parties.  Any Old Notes so  withdrawn  will be  deemed  not to have been
validly  tendered for exchange for purposes of the Exchange Offer. Any Old Notes
which have been tendered for exchange but which are not exchanged for any reason
will be returned to the holder  thereof  without cost to such holder (or, in the
case of Old 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,  such Old Notes will be credited to an account with
such  Book-Entry   Transfer  Facility  specified  by  the  holder)  as  soon  as
practicable after withdrawal, rejection of tender or termination of the Exchange

                                                          39





Offer.  Properly  withdrawn  Old Notes may be retendered by following one of the
procedures  described under  "--Procedures for Tendering Old Notes" above at any
time on or prior to the Expiration Date.

ACCOUNTING TREATMENT

result of the  Exchange  Offer.  The  expenses  of the  Exchange  Offer  will be
amortized over the term of the New Notes.

TRANSFER TAXES

  Holders who tender their Old Notes for  exchange  will not be obligated to pay
any transfer taxes in connection therewith, except that holders who instruct the
Company  to  register  New Notes in the name of, or  request  that Old 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 the payment of any
applicable transfer tax thereon.

REGULATORY MATTERS

  The Company is not aware of any governmental or regulatory  approvals that are
required in order to consummate the Exchange Offer.

CONSEQUENCES OF FAILURE TO EXCHANGE

     Participation in the Exchange Offer is voluntary.  Holders of the Old 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  Notes  that  are not  exchanged  for the New  Notes  pursuant  to the
Exchange Offer will remain restricted  securities.  Accordingly,  such Old Notes
may only be offered,  sold, pledged or otherwise  transferred (A)(i) to a person
whom the seller reasonably  believes is a qualified  institutional  buyer within
the meaning of Rule 144A in a transaction meeting the requirements of Rule 144A,
(ii) in an offshore transaction meeting the requirements of Rule 903 or Rule 904
of Regulation S under the Securities Act, or (iii) pursuant to an exemption from
registration  under the  Securities  Act  provided  by Rule 144  thereunder  (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

  In the event of a Registration  Default (as hereinafter  defined),  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
such  Registration  Default  shall occur 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 at maturity of the 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 at maturity of the
7.50% Notes at the end of each subsequent  90-day period,  but in no event shall
such rates exceed 2.0% per annum in the aggregate regardless of the number of

                                                          41





Registration Defaults. See "Description of the 7.50% Notes--Exchange Offer;

broker-dealer.

                           DESCRIPTION OF THE 7.50% NOTES

GENERAL

  The New 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 Notes and the Old Notes collectively. The New Notes and the Old Notes
are  considered  collectively  to be a single class for all  purposes  under the
Indenture, including, without limitation,  waivers, amendments,  redemptions and
Offers to Purchase.

  The following summary of certain  provisions of the Indenture does not purport
to be 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  therein 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 Notes will be senior  unsecured  obligations  of the Company,  ranking
pari passu in right of payment  with all existing  and future  senior  unsecured
indebtedness of the Company,  including the 10 7/8% Notes,  the 9.47% Notes, the
8.29% Notes,  the 7.25% Notes Due 2008 and the 7.25% Notes Due 2007, and will be
senior in right of  payment  to all  existing  and  future  indebtedness  of the
Company  expressly  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  constituted  secured  indebtedness  or subordinated
indebtedness.

  The  operations of the Company are  conducted  through its  subsidiaries  and,
therefore,  the Company is dependent  upon 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 10 7/8% Notes,  the repayment of $57.3 million of
the equipment  credit  facility,  the offering of the 7.25% Notes Due 2008, this
offering of the 7.50%  Notes and the use of the  proceeds  therefrom,  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

                                                          45





substantial additional indebtedness 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 such  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 annum 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  preceding April 15 and October 15. Interest will be computed on
the basis of a 360-day year  comprised of 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 thereof.  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 of a sum  sufficient  to cover any transfer
tax or other similar  governmental charge payable in connection  therewith.  The
interest  rate on the 7.50% Notes is subject to  increase  in the  circumstances
(such additional interest being referred to as "Liquidated  Interest") described
under "Exchange Offer;  Registration  Rights." All references herein to interest
on the 7.50% Notes shall include such Liquidated Interest, if appropriate.

Book-Entry System

  The New Notes will  initially be issued in the form of Global  Securities  (as
defined  in the  Indenture)  held in  book-entry  form.  The New  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 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.  Upon  the
issuance of a Global Security, 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 such
Global Security purchased by such persons in the offering of the New Notes. Such
accounts shall initially be designated by the initial purchaser of the New Notes

                                                          46





with  respect to New Notes  placed 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 such Global  Security.  Ownership  of  beneficial
interests in such Global Security by persons that hold through participants will
be shown on, and the transfer of that ownership interest within such participant
will be effected only through, records maintained by such participant.  The laws
of some  jurisdictions  require  that  certain  purchasers  of  securities  take
physical  delivery of such  securities in definitive  form. Such limits and such
laws may  impair  the  ability  to  transfer  beneficial  interests  in a Global
Security.  Payment of principal of,  premium,  if any, and interest on New Notes
represented  by any such Global  Security will be made to the  Depository or its
nominee, as the case may be, as the sole registered owner and the sole holder of
the New Notes represented thereby for all purposes under the Indenture.  None of
the Company, the Trustee, any agent of the Company or the initial purchaser will
have any responsibility or liability 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 Notes or for  maintaining,  supervising or
reviewing any of the Depository's  records relating to such beneficial ownership
interests.  The Company has been advised by the Depository  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 respective  beneficial interests in the principal or face
amount of such 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 such 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 such participants. So long as the Depository or its nominee is
the registered owner or holder of such Global  Security,  the Depository or such
nominee,  as the case may be, will be considered the sole owner or holder of the
New Notes  represented  by such Global  Security  for the  purposes of receiving
payment on the New Notes, receiving notices and for all other purposes under the
Indenture  and the New  Notes.  Beneficial  interests  in the New Notes  will be
evidenced only by, and transfers thereof 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 such 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 such
person is not a participant,  on the procedures of the participant through which
such person owns its  interest,  to  exercise  any rights of a holder  under the
Indenture.  The Company understands that under existing industry  practices,  in
the event that the Company  requests any action of holders or that an owner of a
beneficial interest in a Global Security desires to give or take any action that
a holder is entitled to give or take under the Indenture,  the Depository  would
authorize the participants holding the relevant beneficial interest to give or

                                                          47





take such action, and such participants would authorize beneficial owners owning
through such  participants  to give or take such action or would  otherwise  act
upon 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 Notes  (including  the  presentation  of New Notes for exchange as
described  below) only at the  direction  of one or more  participants  to whose
account with the  Depository  interests in the Global  Security are credited and
only in respect of such  portion of the  aggregate  principal  amount of the New
Notes as to which  such  participant  or  participants  has or have  given  such
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 such  securities  through
electronic   book-entry  changes  in  accounts  of  the  participants,   thereby
eliminating  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 Notes

  New Notes  represented by a Global Security are  exchangeable for certificated
New Notes only if (i) the  Depository  notifies the Company that it is unwilling
or unable to continue as a depository for such Global Security or if at any time
the Depository ceases to be a clearing agency registered under the Exchange Act,
and a successor  depository is not appointed by the Company within 90 days, (ii)
the  Company  executes  and  delivers  to the  Trustee a notice that such Global
Security  shall  be so  transferable,  registrable  and  exchangeable,  and such
transfer  shall be  registrable  or  (iii)  there  shall  have  occurred  and be
continuing  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 Notes  represented  by such Global  Security.  Any Global  Security  that is
exchangeable for certificated New Notes pursuant to the preceding  sentence will
be transferred to, and registered and exchanged for,  certificated  New Notes in
authorized  denominations  and registered in such names as the Depository or its
nominee  holding such Global  Security may direct.  Subject to the foregoing,  a
Global  Security  is not  exchangeable,  except  for a Global  Security  of like
denomination  to be registered in the name of the Depository or its nominee.  In
the event that a Global  Security  becomes  exchangeable  for  certificated  New
Notes,  (i)  certificated New Notes will be issued only in fully registered form
in  denominations  of $1,000 or  integral  multiples  thereof,  (ii)  payment of
principal, any repurchase price, and interest on the certificated New Notes will
be payable, and the transfer of the certificated New Notes will be registrable,

                                                          48





at the office or agency of the Company maintained for such purposes and (iii) no
service  charge  will be made for any  issuance of the  certificated  New Notes,
although the Company may require payment of a sum sufficient to cover any tax or
governmental  charge  imposed  in  connection  therewith.   In  addition,   such
certificates  will bear the legend referred to under "Notice to  Investors--Rule
144A" (unless the Company  determines  otherwise in accordance  with  applicable
law) subject, with respect to such New Notes, to the provisions of such legend.

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  upon not less than 30 and not more than 60 days'
prior notice at a redemption price equal to the principal  amount thereof,  plus
accrued and unpaid  interest  thereon (if any) to the  redemption  date plus the
Applicable  Make-Whole  Premium.  For  purposes  of this  "Optional  Redemption"
provision,   the  following  definitions  shall  apply:  "Applicable  Make-Whole
Premium" means, with respect to any Note, the excess of (A) the present value at
the redemption date of the required interest and principal  payments due on such
Note,  computed using a discount rate equal to the Treasury Rate plus 37.5 basis
points, over (B) the then outstanding  principal amount of such 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 such 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 such 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 such 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 such  release  (or any
successor  release) is not  published  or does not  contain  such prices on such
business day, (A) the average of the Reference  Treasury  Dealer  Quotations (as
defined below) for such 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 such  Reference  Treasury  Dealer at 5:00 p.m. on the
third business day preceding such 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

                                                          49





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").  In the event that
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 such 7.50%  Notes  below the  required
Investment Grade Ratings, then the Company and its Restricted  Subsidiaries will
thereafter  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 such covenant
had  been in  effect  since  the  date  of the  Indenture.  Notwithstanding  the
foregoing,  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
preceding sentence,  anticipation and reasonable belief may be determined by the
Company and shall be conclusively evidenced by a board resolution to such effect
adopted in good faith by the

                                                          50





Board of Directors of the Company.  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 thereof,  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  thereof,  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  thereof 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  thereof,  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 Notes,  the offering of the 7.25% Notes and the
use of proceeds therefrom,  the Company's  Consolidated Capital Ratio would have
been approximately 0.6 to 1.0. (b) Notwithstanding 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

Dispositions"  above to the extent such  provisions  apply and (y) the Company's
remaining  Investment in such Permitted  Joint Venture would have been permitted
as a  new  Investment  under  the  provisions  of  "--Limitation  on  Restricted
Payments"

                                                          58





above,  (iii) the  transfer,  conveyance,  sale or other  disposition  of shares
required by  applicable  law or  regulation,  (iv) if  required,  the  issuance,
transfer, conveyance, sale or other disposition of directors' qualifying shares,
or (v) Disqualified  Stock issued in exchange for, or upon conversion of, or the
proceeds  of the  issuance  of which are used to redeem,  refinance,  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  required  by, the
Disqualified Stock being exchanged, converted, redeemed, refinanced, replaced or
refunded.

Transactions  with Affiliates and Related Persons.  The Company may not, and may
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)

                                                          59





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  thereof,  other than any Permitted  Holder or any
Restricted  Subsidiary,  shall have occurred;  (B) any Person or Group, together
with any Affiliates or Related Persons thereof,  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.  In the event  that 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."  In the event that 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  herein 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

                                                          60





Reports").  In the event 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  thereof  may (upon  notice,  lapse of time or both)  declare a
default  thereon or cause the payment thereof 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

                                                          61





 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 Company  (other
than a merger of Qwest  Corporation  into the Company in which the Company shall
be the surviving Person) or (ii) directly or indirectly,  transfer,  sell, lease
or  otherwise  dispose  of all or  substantially  all of its assets to any other
Person or Persons  unless:  (a) in a transaction in which the Company is not the
surviving 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  thereof or the  District  of
Columbia and shall expressly  assume, by a supplemental  indenture  executed and
delivered  to the  Trustee  in  form  satisfactory  to the  Trustee,  all of the
Company's respective obligations under the Indenture; (b) immediately before and
after giving effect to such  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 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,  the Company  (including any successor entity to the Company) could
Incur at least  $1.00 of  additional  Debt  pursuant  to the  provisions  of the
Indenture  described in paragraph (a) under  "--Limitation on Consolidated Debt"
above;  (e) if, as a result of any such  transaction,  property or assets of the
Company  would become  subject to a Lien  prohibited  by the  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; and (f) certain other conditions are met.

Certain Definitions

  Set forth  below is a summary  of  certain  of the  defined  terms used in the

respect to any Person means the power to direct the  management  and policies of

"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

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

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

(c) default in the payment of principal and interest on 7.50% Notes  required to

(f) default under the terms of any instrument evidencing or securing Debt of the

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

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 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 Note for  enforcement of payment of the principal of
and  premium,  if any, or interest on such Note on or after the  respective  due
dates  expressed  in such 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

                                                          78





indentures  supplemental  to the  Indenture  (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  therein 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 Note (1) change the Stated Maturity of the principal of, or any
installment  of  interest  on,  any  Note,  or alter the  redemption  provisions
thereof,  or reduce the principal  amount  thereof (or premium,  if any), or the
interest thereon that would be due and payable upon maturity thereof,  or change
the place of payment  where,  or the coin or currency in which,  any 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  thereof;  (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
herein).  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
Note,  or (2) in respect of a  covenant  or  provision  hereof  which  under the
proviso to the prior paragraph cannot be modified or amended without the consent
of the holder of each outstanding 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

                                                          79





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  thereof,  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

                                                          80





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 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 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 Notes
for the New  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 Note
surrendered to the Company  pursuant to the Exchange  Offer,  the holder of such
Old Note will  receive an Exchange  Note  having a principal  amount at maturity
equal to that of the surrendered Old Note.

  Based upon  no-action  letters  issued by the staff of the Commission to third
parties, the Company believes that the New Notes issued pursuant to the Exchange
Offer in exchange  for Old Notes would in general be freely  transferable  after
the Exchange Offer without further  registration under the Securities Act if the
holder of the New 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 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 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

                                                          81





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 Notes wishing to accept the Exchange  Offer must represent to the
Company that such conditions have been met. Each broker-dealer that receives New
Notes for its own account pursuant to the Exchange Offer,  where it acquired the
Old  Notes  exchanged  for such New  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 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 Notes  received  in  exchange  for Old Notes where such Old
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  consummation  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 Notes" and
"Plan of Distribution."

  Each holder of the Old Notes (other than certain specified holders) who wishes
to exchange  Old Notes for New Notes in the  Exchange  Offer will be required to
represent  that (a) it is not an affiliate of the Company,  (b) any New 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  Notes.  If  the  holder  is a  broker-dealer  (a
"Participating Broker-Dealer") who acquired the Old 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 Notes.  The Commission
has taken the  position  that  Participating  Broker-Dealers  may fulfill  their
prospectus  delivery  requirements  with  respect to the New Notes (other than a
resale of an unsold  allotment from the original sale of the Old 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 Notes.

  If, (i) because of any change in law or applicable  interpretations thereof 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 Notes, or (iii)

                                                          82





the initial purchaser so requests with respect to Old Notes held by it following
consummation  of the Exchange Offer, or (iv) any holder of Old Notes (other than
the initial  purchaser of the Old Notes) is not eligible to  participate  in the
Exchange  Offer or (v) if the initial  purchaser  participates  in the  Exchange
Offer or  acquires  New Notes  issued  and  delivered  to it by the  Company  in
exchange for Old Notes,  such purchaser  does not receive  freely  tradeable New
Notes in exchange for Old 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 Notes or the New 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 Notes or New 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 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 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 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 Notes
or declared  effective  within 150 days after the closing date of the Old Notes,
or the Exchange Offer has not been consummated within 180 days after the closing
date of the Old Notes or (ii) in lieu thereof, the Shelf Registration  Statement
has not been filed with the  Commission and declared  effective  within 210 days
after the closing date of the Old 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
Notes or New 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 Notes (in  addition  to the stated  interest  on the Old
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 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 Notes at the end of each subsequent 90-day period,

                                                          83





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

  The summary herein of certain  provisions of the  Registration  Agreement does
not purport to be complete  and is subject to, and is  qualified in its entirety

                       DESCRIPTION OF CERTAIN INDEBTEDNESS

  In March 1997, the Company issued and sold $250.0 million in principal  amount
of its 10 7/8%  Senior  Notes Due 2007 (the "10 7/8%  Notes"),  the  proceeds of
which were used to repay  certain  indebtedness  of the Company and also to fund
capital  expenditures  for the  construction  and  activation  of the  Company's
network.  Unamortized  issuance  costs totaling  approximately  $8.0 million are
being  amortized  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, commencing
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 thereof 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 thereof
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  issued $555.9  million in principal  amount at
maturity of its 9.47% Senior Discount Notes Due 2007 (the "9.47% Notes"),

                                                          85





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
net proceeds were used 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.
See "Description of the Notes."

  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  issued $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 net
proceeds were used 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

                                                          86





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 issued and sold the 7.50% Notes,  the proceeds of
which were used 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 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 issued and sold $300.0 million in principal
amount of its 7.25%  Notes Due 2008,  the  proceeds  of which  were used 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

                                                          87





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;  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.  The Credit Facility expired on December 31, 1998. In
November 1998, the outstanding balance under the Credit Facility was repaid with
a portion of the proceeds from the 7.50% Notes.

  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  executed 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 with the remainder expected to be provided by other banks to be added to

                                                          88





the syndicate.  Subsequent to this, the Company obtained other financing through
the  issuance of $300.0  million of 7.25%  Senior  Notes due 2008 and through an
investment  in the  Company of $200.0  million by  Microsoft  Corporation.  As a
result of entering into these  transactions,  the closing of the credit facility
was  postponed.  The Company is  currently  in the process of  obtraining  a new
unsecured  $750.0 million to $1.0 billion credit facility through a syndicate of
banks.  Consummation  of the new credit  facility  is  conditioned,  among other
things,  on the  execution  of 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 Notes
who purchased the Old Notes for cash pursuant to the Offering,  exchange the Old
Notes for New Notes  pursuant to this Exchange  Offer and hold the Old Notes and
will hold the New Notes as capital  assets (such  persons are referred to herein
as  "Holders").  This  discussion is intended only as a descriptive  summary and
does not purport to be 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  herein.  This
discussion is based on the current  provisions  of the Internal  Revenue Code of
1986,   as  amended  (the   "Code"),   the   applicable   Treasury   regulations
("Regulations"),  and public administrative and judicial  interpretations of the
Code and Regulations, all of which are subject to change, which changes 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

                                                          90





matters described herein 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.  There can be no
assurance that the Service will not take a different position concerning the tax
consequences  of the  exchange  of Old Notes for New Notes or the  ownership  or
disposition  of the New  Notes,  or that the  Service's  position  would  not be
sustained by a court.

     The United  States  federal  income tax  consequences  to a Holder may vary
depending  upon the Holder's  particular  situation or status.  Holders that are
subject  to  special  rules  under  the  Code  (including  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 herein, Non-U.S.  Holders (as defined below)) may be subject
to special rules not discussed below.

     As used in this discussion, the term "U.S. Holder" means a Holder that, for
United States federal  income tax purposes,  is (i) a citizen or resident of the
United  States,  (ii) 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,  (iii) an estate  the income of which is subject to
United States federal income tax,  regardless of its source,  or (iv) 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 NOTES FOR NEW NOTES AND OF HOLDING AND DISPOSING OF THE
NEW 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 THEREOF SINCE THE DATE OF THIS PROSPECTUS.

     Although  there is no direct  authority  as to whether the  exchange of Old
Notes for New Notes  pursuant to the Exchange Offer will be treated as a taxable
exchange for United States  federal  income tax  purposes,  it is the opinion of
Holme  Rboberts & 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 upon the exchange of Old Notes for New Notes pursuant to the Exchange Offer
and, upon such exchange,  should have the same adjusted tax basis in and holding
period  for the New  Notes as it had in the Old Notes  immediately  prior to the
exchange.

Original Issue Discount

     Qwest was advised by the Initial  Purchaser  at the time of the sale of the
Old Notes that the Initial  Purchaser  intended to sell the Old Notes at a price
equal to  99.324%  of the stated  principal  amount of the Old Notes,  and Qwest
believes that  substantially all of the Old Notes were sold to investors at that
price.  This  discussion is therefore based on the assumption that the Old 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,  if any, will be considered  zero for United States  federal  income tax
purposes. Each U.S. Holder is required to include stated

                                                          91





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

Effect of Liquidated Interest

  Pursuant  to the  Registration  Agreement,  Qwest  has  agreed to  commence  a
registered  Exchange Offer pursuant to a Registration  Statement or to cause the
7.50%  Notes to be  registered  under the  Securities  Act  pursuant  to a Shelf
Registration  Statement  within  the time  periods  set  forth  therein.  If the
applicable deadlines are not met with respect to the Exchange Offer or the Shelf
Registration Statement, additional interest (in the form of Liquidated Interest)
will accrue and be payable  semiannually  with respect to the 7.50%  Notes.  See
"Exchange  Offer  Registration  Rights" and  "Description  of the 7.50%  Notes."
Although the treatment is not free from doubt,  the provision for the payment of
Liquidated  Interest probably  constitutes  contingent  payments for purposes of
computing  original issue discount.  Qwest believes that it is unlikely that the
Exchange Offer and Shelf Registration Statement requirements of the Registration
Agreement will not be met, and thus, that  Liquidated  Interest will be required
to be paid with respect to the 7.50% Notes. Accordingly,  Qwest intends to treat
the  Liquidated  Interest  contingency as remote and thus that it will not occur
for  purposes  of  computing  original  issue  discount.  If,  contrary  to this
assumption,  Liquidated Interest is triggered, then the additional interest will
be  reportable  as income at that time or will be  reflected  as original  issue
discount on the 7.50% Notes. Also, if Liquidated Interest is triggered, the U.S.
Holder may be subject to special rules applicable to gains or losses  recognized
on the disposition of a contingent payment debt instrument.

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

                                                          92





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,  such 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
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 measured by the difference
between (i) the amount of cash plus the fair market  value of property  received
in exchange therefor (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  (i)  the  payee   fails  to  furnish  a  taxpayer
identification  number ("TIN") to the payor, (ii) the Service notifies the payor
that the TIN furnished by the payee is incorrect,  (iii) 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 (iv)  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

                                                          93





     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 such 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 purport to cover all aspects of United States federal taxation that
may apply to, or the actual tax effect that any of the matters described herein
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,  if any, on the 7.50% Notes,
and interest paid on the 7.50% Notes, provided that (i) 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,  (ii) 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,
(iii) such interest is not  effectively  connected with a United States trade or
business and (iv) 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 holds the 7.50%  Notes,  certifies to Qwest or it
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  thereof  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 do
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.


                                                          94





     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 Note
in the same manner as if it were a U.S.  Holder.  In addition,  if such 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:  (i)(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, (ii) 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 (iii) 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 percent 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

                                                          95





subject  to  information  reporting,  unless  (i) 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  (ii)  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 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 Notes for its own account pursuant to the
Exchange Offer must  acknowledge that it will deliver a prospectus in connection
with any  resale of such New  Notes.  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 Notes  received  in  exchange  for Old Notes where such Old
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
consummation 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 Notes by any
broker-dealer.  New 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 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 such 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 Notes.  Any  broker-dealer
that resells New Notes that were received by it for its own account  pursuant to
the Exchange Offer and any broker or dealer that participates in a distribution

                                                          96





of such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities  Act  and  any  profit  on any  such  resale  of New  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 consummation 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 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 Notes to be received in the Exchange Offer.


                                 LEGAL MATTERS

  The validity of the New Notes and certain  other legal  matters in  connection
with the New Notes offered hereby are being passed upon for the Company by Holme
Roberts & Owen LLP,  Denver,  Colorado  with respect to matters of United States
law.  Certain  United States  federal income tax matters will be passed upon for
the Company by Holme Roberts & Owen LLP, Denver, Colorado.

                       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.

   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





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.
