        [PRELIMINARY DRAFT DATED JUNE 21, 1999, SUBJECT TO COMPLETION]

                    QWEST COMMUNICATIONS INTERNATIONAL INC.

                               IMPORTANT NOTICE

The information contained in this joint proxy statement/prospectus is highly
preliminary and subject to change. It is presented by Qwest Communications
International Inc. ("Qwest") in order to describe transactions between Qwest
and U S WEST, Inc. ("U S WEST"), on the one hand, and Qwest and Frontier
Corporation ("Frontier"), on the other hand, that would occur if and only if
the transactions proposed by Qwest to U S West and Frontier on June 13, 1999
were accepted in the forms described in this joint proxy statement/prospectus.
Both U S WEST and Frontier are parties to agreements with Global Crossing Ltd.
that prohibit U S WEST and Frontier from discussing with Qwest the
transactions proposed by Qwest except in limited circumstances. At this date,
neither U S WEST nor Frontier has indicated that it intends to discuss the
proposal with Qwest or to accept Qwest's proposal, either in its current form
or in some other form that might subsequently be proposed by Qwest, U S WEST,
Frontier or any other person. There can be no assurance that either Qwest
proposal will be accepted, or that if either Qwest proposal were accepted,
whether the proposal would be accepted in its current form or in some other
form.

This joint proxy statement/prospectus does not constitute or commence a tender
offer or exchange offer for any securities of U S WEST or Frontier. This joint
proxy statement/prospectus also does not, at this date, constitute or commence
a proxy solicitation for any matter that is subject to, or may be submitted
for, approval by the shareholders of either U S WEST or Frontier. Unless and
until Qwest enters into a transaction with U S WEST or Frontier or both and
revises this joint proxy statement/prospectus accordingly, shareholders of U S
WEST and Frontier should not tender any securities for purchase by Qwest or
deliver to Qwest a proxy to vote any shares of U S WEST or Frontier common
stock with respect to any matter whatsoever.

The joint proxy statement/prospectus is prepared on the assumption that it is
a joint proxy statement/prospectus of Qwest, U S WEST and Frontier. As of this
date, the boards of directors of U S WEST and Frontier have not reviewed or
approved this joint proxy statement/prospectus, approved the transactions
proposed by Qwest or called meetings for their shareholders to consider
approving the transactions. The actual joint proxy statement/prospectus for
any transaction or transactions that may be entered into between Qwest, on the
one hand, and U S WEST and Frontier, on the other hand, may differ
substantially from this joint proxy statement/prospectus.

Information in this joint proxy statement/prospectus is presented only as of
the date hereof. We do not intend to file an amended or revised joint proxy
statement/prospectus unless and until we enter into a transaction with U S
WEST or Frontier or both.


- -------------------------------------------------------------------------------
Neither the Securities and Exchange Commission nor any state securities
regulators have approved the Qwest stock to be issued under this Joint Proxy
Statement/Prospectus or determined if this Joint Proxy Statement/Prospectus is
accurate or adequate. Any representation to the contrary is a criminal
offense.
- -------------------------------------------------------------------------------

    Joint Proxy Statement/Prospectus dated _____ __, 1999, and first mailed
                     to shareholders on __________, 1999.

                                  THE MERGERS
                       SEE CAUTIONARY NOTE ON COVER PAGE


                    QUESTIONS AND ANSWERS ABOUT THE MERGERS

Q: When and where are the shareholder meetings?

A: The shareholder meeting of Qwest Communications International Inc. ("Qwest")
will take place on [__________], 1999 in Denver, Colorado. The shareholder
meeting of U S WEST, Inc. ("U S WEST") will take place on [__________], 1999
in _________, _________. The shareholder meeting of Frontier Corporation
("Frontier") will take place on [___________], 1999 in _________, _________.

Q: What do I need to do now?

A: Just mail your signed proxy card in the enclosed return envelope or vote by
telephone or the internet, as soon as possible, so that your shares may be
represented at your meeting. In order to assure that your vote is obtained,
please give your proxy as instructed on your proxy card even if you currently
plan to attend your meeting in person.

Q: What should I do if I want to change my vote?

A: Just send in a later-dated, signed proxy card to your company's Secretary
or vote again by telephone or the internet before your meeting. Or, you can
attend your meeting in person and vote. You may also revoke your proxy by
sending a notice of revocation to your company's Secretary at the address
under "Summary- The Companies".

Q: If my shares are held in "street name" by my
broker, will my broker vote my shares for me?

A: If you do not provide your broker with instructions on how to vote your
"street name" shares, your broker will not be permitted to vote them on the
mergers. You should therefore be sure to provide your broker with instructions
on how to vote your shares. Please check the voting form used by your broker
to see if it offers telephone or internet voting. If you are a Qwest
shareholder and do not give voting instructions to your broker, you will not
be counted as voting for purposes of your merger proposals unless you appear
in person at the Qwest meeting.

If you are a U S WEST or Frontier shareholder and do not give voting
instructions to your broker, you will, in effect, be voting against your
merger unless you appear in person at your shareholder meeting and vote in
favor of your merger.

Q: Should I send in my stock certificates now?

A: No.  If the mergers are completed, we will send U S WEST and Frontier
shareholders written instructions for exchanging their share certificates.
Qwest shareholders will keep their existing certificates.

Q: What happens to my future dividends?

A: We expect no changes in the dividend policies of any of the three companies
before the mergers. The payment of dividends by the combined company in the
future, however, will depend on business conditions, the combined company's
financial condition and earnings, and other factors.

Q: When do you expect the mergers to be completed?

A: We are working towards completing the mergers as quickly as possible.  In
addition to shareholder approvals, we must also obtain regulatory approvals.
We hope to complete the mergers by [___________].

Q: Who do I call if I have questions about the meetings or the mergers?

A: Qwest shareholders may call 1-800-[___]-[____].
U S WEST shareholders may call 1-800-[___]-[____].
Frontier shareholders may call 1-800-[___]-[____].

 (3)  a law or court order permanently prohibits the U S WEST merger; or

      of a superior proposal, that failure to terminate

            agreement U S WEST enters into an agreement for an alternative
            transaction with any third party, or

S WEST and [___] directors designated by Frontier. Qwest expects that Mr.

Regulatory Approvals

Completion of the mergers will not occur until after receipt of certain

Division of the Justice Department or the Federal Trade Commission. In
addition, the mergers cannot be completed until permission is obtained from
the Federal Communications Commission and certain state public utility
commissions regarding the transfer of control of the U S WEST and Frontier
telephone operations. Qwest may find that other regulatory approvals are
required after it has an opportunity to conduct due diligence investigations
with respect to ancillary U S WEST and Frontier operations. None of these
regulatory approvals have been requested at this time. See "The Mergers--
Regulatory Matters Relating to the U S WEST Merger" and "The
Mergers--Regulatory Matters Relating to the Frontier Merger."

Material Federal Income Tax Consequences of the Mergers

A U S WEST shareholder's receipt of Qwest common stock in the U S WEST merger
generally will be tax-free for United States federal income tax purposes,
except for tax resulting from the receipt of cash instead of any fractional
share of Qwest common stock.

A Frontier shareholder's receipt of Qwest common stock in the Frontier merger
generally will be tax-free for federal income tax purposes, except for tax
resulting from the receipt of cash instead of any fractional share of Qwest
common stock and except for tax on any gain on that shareholder's Frontier
common stock to the extent of other cash received in the Frontier merger.

consummation of the Frontier merger, and consummation of the Frontier merger
is not conditioned on consummation of the U S WEST merger.

U S WEST and Frontier Information

     While Qwest has included herein information concerning U S WEST and
Frontier insofar as it is known or reasonably available to Qwest, U S WEST and
Frontier are not affiliated with Qwest and neither U S WEST nor Frontier has
permitted Qwest access to its books and records. Therefore, information
concerning U S WEST and Frontier that has not been made public is not
available to Qwest. Qwest was not involved in the preparation of such

information or statements and accepts no responsibility for the accuracy or

Background of the Mergers

     [Further background to come.]

     The Global Acquisition Proposals.

     On March 16, 1999, Global, Frontier and GCF Acquisition Corp. ("Global
Merger Sub"), a wholly-owned subsidiary of Global, announced that they had
entered into the Original Global/Frontier Merger Agreement, under which Global
Merger Sub would merge into Frontier, causing Frontier to become a
wholly-owned subsidiary of Global, and the stockholders of Frontier would
receive a combination of cash and Global Common Stock. Under the Original
Global/Frontier Merger Agreement, each share of Frontier Common Stock was to
be exchanged for Global Common Stock valued at $62.00 per common share (with a
"collar" provision adjusting the exchange ratio to maintain a constant value
of Global Common Stock per Frontier share if the price of Global Common Stock
was within the collar). According to the materials filed by Frontier on Form
8-K on March 19, 1999 (the "Frontier March 8-K"), the Boards of Directors of
both Frontier and Global had approved the Original Global/Frontier Merger
Agreement, and shareholders of Global representing more than a majority of the
outstanding Global Common Stock agreed to vote their shares in favor of the
contemplated transactions. Frontier also agreed to grant Global an option to
purchase shares representing 19.9% of its outstanding common stock for $62.00
per share, exercisable upon termination of the Original Global/Frontier Merger
Agreement in certain circumstances. For additional information about the
Original Global/Frontier Merger Agreement, see the Frontier March 8-K.

     On May 16, 1999, Global and U S WEST announced that they had entered into
the Global/U S WEST Merger Agreement, under which the shareholders of U S WEST
and Global/Frontier would become the owners of a newly-created holding company
to be named Global Crossing Corporation ("New Holdco"). U S WEST and Global
would become subsidiaries of New Holdco, and New Holdco would establish two
classes of tracking stock. The Class G stock would track the global data and
voice network and internet assets of New Holdco, and the Class L stock would
track the local telecommunications assets. Under the Global/U S WEST Merger
Agreement, each share of U S WEST stock would be exchanged for approximately
1.2 shares of New Holdco tracking stock, and each share of Global common stock
would be exchanged for one share of New Holdco tracking stock. Shareholders
could elect which class of tracking stock they would receive, subject to
proration based on an appraisal of the relative values of the two classes of
assets to be done shortly before closing. According to the materials filed by
U S WEST on Form 8-K on May 21, 1999 (the "U S WEST May 8-K") and the
materials filed by Global on Form 8-K on May 18, 1999 (the "Global May 8-K"),
the Boards of Directors of both U S WEST and Global had approved the Global/U
S WEST Merger Agreement, and shareholders of Global representing more than a
majority of the outstanding Global Common Stock agreed to vote their shares in
favor of the contemplated

transactions. In addition, according to the Schedule 14D-1 filed by U S WEST
on May 21, 1999 (as amended from time to time, the "U S WEST Schedule 14D-1"),
U S WEST agreed to make a cash tender offer (the "Tender Offer") for
approximately 9.5% of the outstanding Global Common Stock at a price of $62.75
per share. The Tender Offer expired on June 18, 1999. For additional
information about the Global/U S WEST Merger Agreement, see the U S WEST May
8-K and the Global May 8-K. For additional information about the Tender Offer,
see the U S WEST Schedule 14D-1.

     Also on May 16, 1999, Global, Global Merger Sub and Frontier entered into
a Consent and Amendment No.1 to the Original Global/Frontier Merger Agreement
(as so amended, the "Global/Frontier Merger Agreement"), pursuant to which (1)
Frontier consented to the Global/U S WEST Merger Agreement and the Tender
Offer and (2) the consideration to be paid for each share of Frontier Common
Stock was increased to $63 per share ($62 if no shares were purchased in the
Tender Offer). For additional information regarding the amendment to the
Global/Frontier Merger Agreement, see the materials filed on Form 8-K on May
18, 1999 by Frontier.

     The Qwest Proposal to U S WEST.

     On June 13, 1999, Philip F. Anschutz, Chairman of the Board of Qwest,
telephoned Solomon D. Trujillo, the Chairman, President and Chief Executive
Officer of U S WEST, to inform him that Qwest would be publicly announcing
that day an offer to acquire all of U S WEST for Qwest Common Stock. On that
same day, Joseph P. Nacchio, the Chairman and Chief Executive Officer of
Qwest, sent Mr. Trujillo the following letter.

     June 13, 1999

     Mr. Solomon D. Trujillo
     Chairman, President and Chief Executive Officer
     U S WEST, Inc.
     1801 California Street
     Denver, Colorado 80202

     Dear Sol:

          Qwest Communications International Inc. is pleased to offer to
     acquire all of U S WEST, Inc. for Qwest common stock. Qwest will pay
     1.738 shares of Qwest common stock for each share of U S WEST common
     stock. Based on Friday's closing price for Qwest shares, our offer has a
     value of $78.00 per share. We are also announcing our offer to acquire
     Frontier Corporation in a stock and cash transaction valued at
     approximately $13.6 billion and, in the event that Frontier accepts our
     proposal and we enter into a merger agreement with Frontier, we will
     increase the consideration payable to U S WEST shareholders to 1.783
     shares of Qwest common stock having a value of $80.00 per U S WEST share.

          If Frontier agrees to a business combination with us, our offer
     would represent a 25.4% premium to the value of U S WEST's proposed
     merger with Global Crossing Ltd. based on the closing price of Global
     Crossing's shares on Friday, a 45.8% premium to Friday's closing price of
     U S WEST and a 28.5% premium to the trading price of U S WEST prior to
     the announcement of its merger agreement with Global Crossing. If we do
     not conclude our business combination agreement with Frontier, our
     proposal would still represent a 22.2% premium to the value of U S WEST's
     proposed merger with Global Crossing, a 42.1% premium to Friday's closing
     price of U S WEST and a 25.3% premium to the trading price of U S WEST
     prior to the announcement of its merger agreement with Global Crossing.

                                                      Chapter One - The Merger


           Neither of our acquisition proposals is conditioned upon the
     success of the other proposal and Qwest is prepared to enter into a
     binding agreement with U S WEST whether or not we conclude our
     transaction with Frontier.

          Upon consummation of the transaction, we will invite you to become
     Vice Chairman of the Qwest Board and we would expect to invite up to four
     members of the current U S WEST Board, including you, to join the Qwest
     Board.

          The combination of our two companies will allow us to combine the
     management talents of both organizations. We expect an extremely smooth
     transition given the fact that we are -- and will remain -- headquartered
     in Denver.

          The combination of our two companies is truly a powerful opportunity
     for our respective shareholders, employees and customers. The combination
     will accelerate the delivery of Internet-based broadband communications
     services to a large customer base and, by bringing together the network
     infrastructure, applications and services as well as the customer
     distribution channels of our companies, will create a truly worldwide
     internet communications powerhouse.

          We believe that the combination will result in significant operating
     synergies, aggregating approximately $9.1 billion to $10.1 billion
     through the year 2005 from our combination and $14 billion through the
     year 2005 from a combination of U S WEST, Frontier and Qwest. These
     synergies are comprised of (i) incremental revenues as the combined
     company expands its local, data, IP and long-distance service; (ii)
     operating cost savings in areas such as network operations and
     maintenance, sales and marketing, billing, customer and back office
     support as well as in procurement efficiencies; and (iii) capital savings
     by eliminating duplication of the companies planned network buildouts and
     in other infrastructure and back-office areas. We are prepared to meet
     with you to discuss the analysis performed by us that underlies these
     synergies and demonstrates their feasibility. Our analysis of synergies
     is based on our analysis of information concerning you that is publicly
     available, and we would expect that working with you we could identify
     significantly greater synergies resulting from a combination of our two
     companies.

          Our proposal is financially superior to your pending transaction
     with Global Crossing. Not only will your shareholders receive a higher
     price for their U S WEST shares in a simpler transaction structure, but
     they will also receive a superior stock reflecting Qwest's premier
     assets, management's operating record, strong growth prospects and the
     greater realizable synergies resulting from our combination.

          Qwest's principal shareholder has indicated its readiness to enter
     into a voting agreement concerning its obligation to vote in favor of the
     merger at the meeting of Qwest shareholders comparable to the agreement
     entered into by Global Crossing's controlling shareholders.

          We are confident of our ability to complete this transaction as
     quickly as the proposed Global Crossing merger. Our legal advisors are
     confident of our ability to obtain all necessary approvals in a timely
     manner and we are prepared to commit to take steps, including disposition
     of certain operations, required to obtain such consents. Our offer will
     be tax-free to U S WEST shareholders and we can provide tax treatment and
     tax consequences of our proposed transaction equivalent to those of the
     Global Crossing transaction.

          We believe that our merger is fully consistent with the policy
     underlying the Telecommunications Act of 1996 and is strongly in the
     public interest. While obtaining regulatory approval under Section 271 of
     the Telecommunications Act is not a condition of the closing of our
     transaction, we would ask you to make the same commitments you have made
     in connection with the Global Crossing transaction to accelerate the
     process of obtaining such approval.

Chapter One - The Merger


          Given the clear superiority of our offer to the proposed Global
     Crossing merger, we would like to meet with you and your advisors as soon
     as possible to finalize a definitive agreement between our companies. The
     offer is, of course, subject to entering into such an agreement. In this
     regard, we are ready to enter into a merger agreement substantially
     similar to the Global Crossing agreement. A copy of the proposed merger
     agreement is attached to this letter. We are also ready to exchange
     confidential information. Qwest is committed to bringing the combination
     between our companies to a successful conclusion and we would be
     delighted to discuss any aspect of our proposal.

          We look forward to meeting at the earliest opportunity to conclude
     this mutually beneficial transaction for both our companies. Please
     forward to us the form of confidentiality agreement we are required to
     execute to further this matter. In addition, we and our advisors will be
     happy to meet with U S WEST at the time of your choosing to answer any
     questions about our proposal. A list of persons who may be contacted at
     Qwest and at our financial and legal advisors is attached to this letter.

                                                       Sincerely,

                                                       /s/ Joseph P. Nacchio

     The Qwest Proposal to Frontier.

     On June 13, 1999, Mr. Anschutz telephoned Joseph P. Clayton, the Chief
Executive Officer of Frontier, to inform him that Qwest would be publicly
announcing that day an offer to acquire all of Frontier for cash and Qwest
Common Stock. On that same day, Mr. Nacchio sent Mr. Clayton the following
letter.

     June 13, 1999

     Mr. Joseph P. Clayton
     Chief Executive Officer
     Frontier Corporation
     180 South Clinton Avenue
     Rochester, New York 14646

     Dear Joe:

          Qwest Communications International Inc. is pleased to offer to
     acquire all of Frontier Corporation for cash and Qwest common stock.
     Qwest will pay $20 in cash and 1.181 shares of Qwest common stock for
     each share of Frontier common stock. Based on Friday's closing price for
     Qwest shares, our cash and stock offer has a value of $73.00 per Frontier
     share. We are also announcing our offer to acquire U S WEST, Inc. in a
     stock-for-stock transaction having total equity market value of
     approximately $41.3 billion and, in the event that U S WEST accepts our
     proposal and we enter into a merger agreement with U S WEST, we will
     increase the consideration payable to Frontier shareholders to $20 in
     cash and 1.226 shares of Qwest common stock having a total value of
     $75.00 per Frontier share.

          The stock portion of our offer will be tax-free to Frontier
     shareholders. If U S WEST agrees to a business combination with us, our
     offer would represent a 19% premium to the value of Frontier's proposed
     merger with Global Crossing Ltd. based on the closing price of Global
     Crossing's shares on Friday, a 35.3% premium to Friday's closing price of
     Frontier and a 68.1% premium to the trading price of Frontier prior to
     the announcement of its merger agreement with Global Crossing. If we do
     not conclude our business combination agreement with U S WEST, our
     proposal would still represent a 15.9% premium to the value of Frontier's

     proposed merger with Global Crossing, a 31.7% premium to Friday's closing
     price of Frontier and a 63.6% premium to the trading price of Frontier
     prior to the announcement of its merger agreement with Global Crossing.

          Neither of our acquisition proposals is conditioned upon the success
     of the other proposal and Qwest is prepared to enter into a binding
     agreement with Frontier whether or not we conclude our transaction with U
     S WEST.

          Upon consummation of the transaction, we will invite up to two of
     Frontier's current directors, including you, to join the Qwest Board.

          The combination of our two companies is truly a powerful opportunity
     for our respective shareholders, employees and customers. The combination
     will accelerate the delivery of Internet-based broadband communications
     services to a large customer base and, by bringing together the network
     infrastructure, applications and services as well as the customer
     distribution channels of our companies, will create a truly worldwide
     internet communications powerhouse.

          We believe that the combination will result in significant operating
     synergies, aggregating approximately $4 billion to $4.5 billion through
     the year 2005 from our combination and $14 billion through the year 2005
     from a combination of U S WEST, Frontier and Qwest. These synergies are
     comprised of (i) incremental revenues as the combined company expands its
     local, data, IP and long-distance service; (ii) operating cost savings in
     areas such as network operations and maintenance, sales and marketing,
     billing, customer and back office support as well as in procurement
     efficiencies; and (iii) capital savings by eliminating duplication of the
     companies planned network buildouts and in other infrastructure and

     analysis performed by us that underlies these synergies and demonstrates
     their feasibility. Our analysis of synergies is based on our analysis of
     information concerning you that is publicly available, and we would
     expect that working with you we could identify significantly greater
     synergies resulting from a combination of our two companies.

          Our proposal is financially superior to your pending transaction
     with Global Crossing. Not only will your shareholders receive a higher
     price for their Frontier shares in a simpler transaction structure, but
     they will also receive a superior stock reflecting Qwest's premier

     greater realizable synergies resulting from our combination.

     into a voting agreement concerning its obligation to vote in favor of the
     merger at the meeting of Qwest shareholders comparable to the agreement
     entered into by Global Crossing's controlling shareholders.

          We are confident of our ability to complete this transaction as
     quickly as the proposed Global Crossing merger. Our offer contains no
     financing contingencies. Qwest has received financing commitments from
     Donaldson, Lufkin & Jenrette Capital Funding, Inc. and Bank of America,
     NT & SA to supplement its existing cash reserves for the purpose of
     funding the cash portion of the consideration to be paid to Frontier
     shareholders and to pay the transaction fees and expenses.

          We believe that our merger is fully consistent with the policy
     underlying the Telecommunications Act of 1996 and is strongly in the
     public interest. Our legal advisors are confident of our ability to
     obtain all necessary approvals in a timely manner.

     On Monday, June 14, 1999, Qwest filed with the Commission on Form 8-K
copies of the letters set forth above, a press release relating to the
proposed transactions, and related presentation materials.

     On Monday, June 14, 1999, Global issued a press release stating that it
believed that its proposals were superior to the Qwest proposals and that it
expected that the mergers would close as planned according to its
previously-announced timetable.

     On Thursday, June 17, 1999, Frontier issued the following press release:

          Frontier Corporation announced today that its Board of Directors has
     reviewed the unsolicited acquisition offer made by Qwest Communications
     International Inc. and has determined to take no action with respect to
     the offer at this time. The Board took into consideration, among other
     things, the uncertainties surrounding Qwest's simultaneous bid for U S
     WEST, the financial terms and structure of the Qwest proposal, current
     market conditions, and the terms of the existing Frontier/Global Crossing
     Ltd. merger agreement.

          Frontier's Board directed management to continue to monitor events
     related to the Qwest proposal, and the Board will take such actions as it
     deems to be in the best interests of the shareholders of Frontier,
     consistent with the existing Global Crossing merger agreement.

          "Our Board discussed the Qwest offer, its impact on our
     shareholders, and its interplay with the separate Qwest offer to acquire
     U S WEST. We have carefully evaluated the bid, and we have discussed the
     issues at length with our advisors," said Frontier Chief Executive
     Officer Joseph P. Clayton. "The current circumstances surrounding the
     Qwest proposal do not warrant any change at this time in our current
     initiatives that are designed to move Frontier's transaction with Global
     Crossing toward a prompt closing."

          Added Clayton, "We remain excited about the strategic and financial
     benefits of the Global Crossing transaction, including the value
     certainty it delivers to our shareholders. We will, of course, continue
     to monitor events and, where appropriate, respond in our shareholders'
     best interests."

     Later on Thursday, June 17, 1999, U S WEST issued the following press
release:

          U S WEST, Inc. announced today that on June 13, 1999, Qwest
     Communications International Inc. ("Qwest") publicly announced that it
     has made an offer to acquire through a merger, all of the outstanding
     shares of Common Stock of U S WEST, Inc. Qwest stated that it will
     exchange 1.738 shares of Qwest Common Stock for each share of U S WEST,
     Inc.'s Common Stock. In addition, Qwest concurrently publicly

     announced that it was offering to acquire all of the outstanding shares
     of Common Stock of Frontier Corporation. In the event Frontier
     Corporation enters into a definitive agreement with Qwest with respect to
     the acquisition of Frontier Corporation by Qwest, Qwest has indicated
     that it will increase the consideration it is offering to 1.783 shares of
     Qwest Common Stock for each share of U S WEST, Inc.'s Common Stock.
     Qwest's proposal is subject to other terms and conditions. The Qwest
     proposal is not subject to completion of, or termination of, the tender
     offer. In addition, Qwest sent a letter to Mr. Solomon D. Trujillo, the
     Chairman, President and Chief Executive Officer of U S WEST, Inc.,
     setting forth the foregoing proposal.

          Notwithstanding the Qwest proposal, pursuant to the Tender Offer and
     Purchase Agreement between U S WEST, Inc. and Global Crossing Ltd., U S
     WEST, Inc. is obligated to purchase the shares pursuant to the tender
     offer unless certain circumstances occur, including the termination of
     the merger agreement between Frontier Corporation and Global Crossing
     Ltd. as a result of the Qwest proposed transactions or otherwise.

          In addition, under the Merger Agreement between U S WEST, Inc. and
     Global Crossing Ltd., U S WEST, Inc. is entitled under certain
     circumstances to consider a Superior Proposal, Pursuant to the Merger
     Agreement, a "Superior Proposal" is defined as a proposal which the Board
     of Directors of U S WEST, Inc. determines in its good-faith judgment,
     based on, among other matters, the advice of a nationally recognized
     financial advisor, to be more favorable to its stockholders than the
     transaction between the U S WEST, Inc. and Global Crossing Ltd., taking
     into account all relevant factors. U S WEST, Inc. has not, at this time,
     made a determination that the Qwest proposal constitutes a Superior
     Proposal as defined in the Merger Agreement. If the Board of Directors of
     U S WEST, Inc. were to determine that Qwest's proposal constituted a
     Superior Proposal for the stockholders of U S WEST, Inc. , U S WEST, Inc.
     would have the right to terminate the Merger Agreement subject to the
     payment of a break-up fee of $850 million of which $250 million can be
     applied against the purchase of services from Global Crossing Ltd. No
     determination has been made as of this time by the Board of Directors of
     U S WEST, Inc.

          In addition, the waiting period under the HSR Act relating to the
     tender offer expired without any request by the Antitrust Division or the
     FTC for additional information.

     [Further background to come.]

     On June 21, 1999, Qwest filed a Registration Statement on Form S-4, of
which this joint proxy statement/prospectus is a part, with the Commission.

Our Reasons for the Mergers

     [To come.]

Recommendations of Our Boards of Directors

     [To come.]

Accounting Treatment

     The mergers will each be accounted for by Qwest as a purchase of a
business. Under this method of accounting, the assets and liabilities of U S
WEST and Frontier will be recorded at their fair value, and any excess of
Qwest's purchase price over such fair value will be accounted for as goodwill.
The revenues and expenses of U S WEST and Frontier will be included in Qwest's
consolidated financial statements from the date of consummation of the
applicable merger.

Chapter One - The Merger


Material Federal Income Tax Consequences of the Mergers

     The following discussion summarizes the opinions, to be delivered at the
closing of the U S WEST merger, of counsel to Qwest and U S WEST, and the
opinions, to be delivered at the closing of the Frontier merger, of counsel to
Qwest and Frontier as to the material United States federal income tax
consequences of the U S WEST merger and the Frontier merger, respectively.
This discussion is based on the Internal Revenue Code of 1986, as amended (the
"Code"), applicable Treasury regulations, administrative interpretations and
court decisions as in effect as of the date of this joint proxy
statement/prospectus, all of which are subject to change, possibly with
retroactive effect.

     This discussion does not address all aspects of federal income taxation
that may be relevant to a shareholder of U S WEST or Frontier in light of that
shareholder's particular circumstances or to a shareholder subject to special
rules, such as:

     o    a shareholder who is not a citizen or resident of the United States,

     o    a financial institution or insurance company,

     o    a tax-exempt organization,

     o    a dealer or broker in securities,

     o    a shareholder that holds its U S WEST common stock or Frontier common
          stock as part of a hedge, appreciated financial position, straddle or
          conversion transaction, or

     o    a shareholder who acquired his U S WEST common stock or Frontier
          common stock pursuant to the exercise of options or otherwise as
          compensation.

     Tax Opinions. It is a condition to the obligations of Qwest and U S WEST
to complete the U S WEST merger, and a separate condition to the obligations
of Qwest and Frontier to complete the Frontier merger, that each receive an
opinion from its counsel, dated as of the closing date of the relevant merger,
that the U S WEST merger or the Frontier merger, respectively, will be treated
for federal income tax purposes as a reorganization within the meaning of
Section 368(a) of the Code and that each of Qwest and, in the case of the U S
WEST merger, U S WEST and U S WEST merger sub, or, in the case of the Frontier
merger, Frontier and Frontier merger sub, will be a party to the
reorganization within the meaning of Section 368(b) of the Code. Qwest does
not currently intend to waive these conditions.

     In rendering these opinions, counsel will rely on representations and
covenants made by Qwest, U S WEST, Frontier and/or others, including those
contained in certificates of officers of Qwest and of U S WEST or Frontier, as
the case may be. These opinions will also rely on assumptions, including
assumptions regarding the absence of changes in existing facts and the
completion of the U S WEST merger or the Frontier merger, as the case may be,
in the manner contemplated by the U S WEST merger agreement or the Frontier
merger agreement, respectively. If any of those representations, covenants or
assumptions is inaccurate, counsel may not be able to render the required
opinions and/or the tax consequences of the mergers could differ from those
discussed here. Opinions of counsel neither bind the IRS nor preclude the IRS
from adopting a contrary position. Qwest does not intend to obtain a ruling
from the IRS on the tax consequences of the mergers.

     Tax Consequences of the U S WEST Merger. For federal income tax purposes:

        o  A holder of U S WEST common stock will not recognize any gain or
           loss upon its exchange of its shares of U S WEST common stock for
           shares of Qwest common stock in the U S WEST merger, except with
           respect to cash received instead of a fractional share of Qwest
           common stock.

        o  To the extent that a holder of U S WEST common stock receives cash
           instead of a fractional share of Qwest common stock, the holder
           will be required to recognize gain or loss, measured by the
           difference between the amount of cash received and the portion of
           the tax basis of that holder's shares of U S WEST common stock
           allocable to that fractional share of Qwest common stock. This gain
           or loss will be capital gain or loss and will be long-term capital
           gain or loss if the share of U S WEST common

           stock exchanged for the fractional share of Qwest common stock was
           held for more than one year at the effective time of the U S WEST
           merger.

        o  A holder of U S WEST common stock will have a tax basis in the
           Qwest common stock received in the U S WEST merger equal to (1) the
           tax basis of the U S WEST common stock surrendered by that holder
           in the U S WEST merger, less (2) any tax basis of the U S WEST
           common stock surrendered that is allocable to a fractional share of
           Qwest common stock for which cash is received.

        o  The holding period for shares of Qwest common stock received in
           exchange for shares of U S WEST common stock in the U S WEST merger
           will include the holding period for the shares of U S WEST common
           stock surrendered in the U S WEST merger.

     Tax Consequences of the Frontier Merger.  For federal income tax purposes:

        o  A holder of Frontier common stock will not recognize any gain or
           loss upon its exchange of its shares of Frontier common stock for
           shares of Qwest common stock in the Frontier merger, except (1)
           that the holder will be taxed on any gain on the shares of Frontier
           common stock surrendered in the Frontier merger to the extent of
           cash (other than cash received instead of a fractional share of
           Qwest common stock) received, and (2) with respect to cash received
           instead of a fractional share of Qwest common stock.

        o  To the extent that a holder of Frontier common stock receives cash
           instead of a fractional share of Qwest common stock, the holder
           will be required to recognize gain or loss, measured by the
           difference between the amount of cash received and the portion of
           the tax basis of that holder's shares of Frontier common stock
           allocable to that fractional share of Qwest common stock. This gain
           or loss will be capital gain or loss and will be long-term capital
           gain or loss if the share of Frontier common stock exchanged for
           the fractional share of Qwest common stock was held for more than
           one year at the effective time of the Frontier merger.

        o  A holder of Frontier common stock will have a tax basis in the
           Qwest common stock received in the Frontier merger equal to (1) the
           tax basis of the Frontier common stock surrendered by that holder
           in the Frontier merger, plus (2) any gain that is recognized by
           that holder as a result of the receipt of cash (other than cash
           received instead of a fractional share of Qwest common stock) in
           the Frontier merger, less (3) any tax basis of the Frontier common
           stock surrendered that is allocable to a fractional share of Qwest
           common stock for which cash is received, less (4) the cash (other
           than cash received instead of a fractional share of Qwest common
           stock) received by that holder in the Frontier merger.

        o  The holding period for shares of Qwest common stock received in
           exchange for shares of Frontier common stock in the Frontier merger
           will include the holding period for the shares of Frontier common
           stock surrendered in the Frontier merger.

     This discussion of material federal income tax consequences is intended
to provide only a general summary, and is not a complete analysis or
description of all potential federal income tax consequences of the mergers.
This discussion does not address tax consequences that may vary with, or are
contingent on, individual circumstances. In addition, it does not address any
non-income tax or any foreign, state or local tax consequences of the mergers.
Accordingly, we urge each shareholder of U S WEST and Frontier to consult his
tax advisor to determine the particular United States federal, state or local
or foreign income or other tax consequences to that shareholder of the U S
WEST merger or the Frontier merger.

Chapter One - The Merger


Regulatory Matters Relating to the U S WEST Merger

     Antitrust Review

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the
rules promulgated under the HSR Act, the U S WEST merger may not be
consummated until notifications have been given and certain information and
materials have been furnished to and reviewed by the Department of Justice and
the Federal Trade Commission and specified waiting period requirements have
been satisfied. As of this date Qwest has not taken any actions in connection
with this requirement. In addition, at any time prior to or after the
consummation of the U S WEST merger, the DOJ or the FTC could take action
under the federal antitrust laws as it deems necessary in the public interest,
including seeking to enjoin the U S WEST merger or seeking conditions thereon.
State antitrust authorities and private parties in certain circumstances may
bring legal action under the antitrust laws seeking to enjoin the U S WEST
merger or seeking conditions.

     Any transaction involving a substantial change in control of U S WEST can
be expected to draw particular scrutiny due to controversies regarding U S
WEST's implementation of those provisions of the Telecommunications Act of
1996 (the "Telecommunications Act") that require U S WEST to take steps to
open its local exchange market to competition. Attention also is likely to
focus on steps that Qwest and U S WEST would take to comply with restrictions
on the provision of interLATA long distance services within the 14 state U S
WEST region. Those restrictions currently apply to U S WEST and would also
apply to Qwest following the U S WEST merger in each U S WEST region state
pending FCC approval of future applications demonstrating that in the
particular state the requirements of Section 271 of the Telecommunications Act
with respect to local exchange competition have been met. Qwest does not
expect that the FCC will have granted such approval in any U S WEST state by
the time that the U S WEST merger otherwise would close. As a result, prior to
closing Qwest will take all action necessary to ensure that at closing the
combined company will not violate the Telecommunications Act, including,
without limitation, the divestiture or termination of interLATA services Qwest
currently provides in the U S WEST region. Notwithstanding the foregoing,
there can be no assurance that a challenge to the U S WEST merger on antitrust
grounds will not be made or, if a challenge is made, what the outcome of the
challenge will be.

     FCC Approval

     Because the U S WEST merger will result in the transfer of control of U S
WEST for purposes of the Communications Act of 1934, as amended (the
"Communications Act"), the prior approval of the FCC is necessary before the U
S WEST merger may be consummated. In reviewing an application for its approval
to the transfer of control, the FCC considers whether such transfers will
serve the public interest, convenience and necessity, including whether the
proposed transferee has the requisite qualifications to operate the licensed
entities. Third parties also have an opportunity to file petitions requesting
the FCC to deny transfer of control applications, or to file comments on such
applications requesting conditions on approval of such applications. Upon
grant of FCC approval, the transaction may be consummated by the parties.
However, for a period after issuance of that approval the FCC action remains
subject to judicial review upon the appeal of a third party, or subject to
reconsideration by the FCC itself. Parties who close transactions during this
period assume the risk that the FCC's approval could be reversed or modified
by the FCC or a reviewing court.

     Qwest has not yet filed an application for consent to the transfer of
control of U S WEST. As noted above, substantial controversy exists with
respect to U S WEST's implementation of those provisions of the
Telecommunications Act that require U S WEST to take steps to open its local
exchange market to competition. Third parties have asked the FCC to condition
mergers involving other Regional Bell Holding Companies ("RBOCs") on further
actions to expand local exchange competition. Although the U S WEST merger
does not involve one RBOC taking control of another, it is possible that third
parties nevertheless will request conditions on the FCC's approval of the
transfer of control of U S WEST to Qwest. Approval of the merger also could be
delayed by issues related to the current restrictions on the provision of
interLATA long distance services within the U S WEST region. As discussed
above, Qwest expects to take actions to comply with those restrictions as of
the

closing of the U S WEST merger, including, without limitation, the divestiture
or termination of its interLATA services in the U S WEST region, pending FCC
approval at a later date after closing of applications demonstrating that the
requirements of Section 271 of the Telecommunications Act with respect to
local exchange competition have been met. Nevertheless, there can be no
assurance that the Commission will grant its approval to the transfer of
control of U S WEST on a timely basis, or without adverse conditions in this
case.

     State Approvals

     Certain state public utility commissions also have jurisdiction to
approve the transfer of control of U S WEST's intrastate local exchange
telephone and long distance operations to Qwest. Qwest will file applications
for consent to the transfer of control of such operations in each state where
such an application is required. Third parties generally have an opportunity
to comment on such applications and in some cases the PUCs may request
additional information or hold hearings. Qwest is aware of controversies in
certain states regarding matters involving U S WEST rates and service quality.
In addition, state PUC proceedings involving transfers of control of other
RBOCs have sometimes been slowed by third party or Commission interest in
conditioning such transfers on commitments by the RBOC to take certain actions
regarding its regulated services, or regarding its implementation of the
requirements of the Telecommunications Act related to opening the local
exchange market to competition. There can be no assurance that the PUC
approval process will be resolved on a timely basis or without material
conditions.

     Other Regulatory Approvals

     Qwest is not presently aware of other regulatory approvals that would be
required in connection with this matter. However, once it has had an
opportunity to conduct further discussions with U S WEST, it is possible that
it will learn of other approval requirements, including potential approval
requirements related to Qwest's operations in other countries. There can be no
assurance that those additionally required approvals, if any, will be obtained
on a timely basis, or without condition.

Regulatory Matters Relating to the Frontier Merger

     Antitrust Review

     Under the HSR Act and the rules promulgated under the HSR Act, the
Frontier merger may not be consummated until notifications have been given and
certain information and materials have been furnished to and reviewed by the
DOJ and the FTC and specified waiting period requirements have been satisfied.
As of this date Qwest has not taken any actions in connection with this
requirement. In addition, at any time prior to or after the consummation of
the Frontier merger, the DOJ or the FTC could take action under the federal
antitrust laws as it deems necessary in the public interest, including seeking
to enjoin the Frontier merger or seeking conditions thereon. State antitrust
authorities and private parties in certain circumstances may bring legal
action under the antitrust laws seeking to enjoin the Frontier merger or
seeking conditions. There can be no assurance that a challenge to the Frontier
merger on antitrust grounds will not be made or, if a challenge is made, what
the outcome of the challenge will be.

     FCC Approval

     Because the Frontier merger will result in the transfer of control of
Frontier for purposes of the Communications Act, the prior approval of the FCC
is necessary before the Frontier merger may be consummated. In reviewing an
application for its approval to a transfer of control, the FCC considers
whether the transfer will serve the public interest, convenience and
necessity, including whether the proposed transferee has the requisite
qualifications to operate the licensed entities. Third parties also have an
opportunity to file petitions requesting the FCC to deny transfer of control
applications, or to file comments on such applications requesting conditions
on approval of such applications. Qwest and Frontier are subject to reduced
FCC regulation, and applications for

                                     I-19

Chapter One - The Merger


consent to the transfer of control of a carrier in these circumstances
generally are processed more rapidly, and are less likely to result in
conditions. Upon grant of FCC approval, the transaction may be consummated by
the parties. However, for a period after issuance of that approval the FCC
action remains subject to judicial review upon the appeal of a third party, or
subject to reconsideration by the FCC itself. Parties who close transactions
during this period assume the risk that the FCC's approval could be reversed
or modified by the FCC or a reviewing court.

     Qwest has not yet filed an application for consent to the transfer of
control of Frontier, and there can be no assurance that the Commission will
grant its approval on a timely basis, or without adverse conditions in this
case.

     State Approvals

     Certain state public utility commissions also have jurisdiction to
approve the transfer of control to Qwest of Frontier's intrastate local
exchange telephone and long distance operations in their respective states.
Qwest will file applications for consent to the transfer of control of such
operations in each state where such an application is required. Third parties
generally have an opportunity to comment on such applications and in some
cases the PUCs may request additional information or hold hearings. Qwest
anticipates that greater PUC review is likely in those states where Frontier
has significant operations as the incumbent local exchange telephone company,
including New York and Iowa. Ordinarily PUC review is reduced where approvals
are requested for the transfer of control of competitive local exchange
operations or intrastate long operations. However, there can be no assurance
that the PUC approval process will move rapidly or be resolved on a timely
basis.

     Other Regulatory Approvals

     Qwest is not presently aware of other regulatory approvals that would be
required in connection with this matter. However, once it has had an
opportunity to conduct discussions with Frontier, it is possible that it will
learn of other approval requirements, including potential approval
requirements related to Qwest's operations in the United Kingdom and Canada.
There can be no assurance that those additionally required approvals, if any,
will be obtained on a timely basis, or without condition.

Appraisal Rights

     Holders of Qwest common stock do not have dissenters' appraisal rights
under Delaware law in connection with the mergers since Qwest is not a
constituent corporation in either of the mergers. Holders of U S WEST common
stock do not have dissenters' appraisal rights under Delaware law in
connection with the U S WEST merger because the shares of Qwest common stock
that such holders will be entitled to receive in the U S WEST merger will be
listed on the NASDAQ at the closing of the U S WEST merger. Holders of
Frontier common stock do not have dissenters' appraisal rights under New York
law in connection with the Frontier merger because Frontier common stock will
be listed on the New York Stock Exchange at the closing of the Frontier
merger.

Federal Securities Laws Consequences; Stock Transfer Restriction Agreements

     This joint proxy statement/prospectus does not cover any resales of the
Qwest common stock to be received by the shareholders of U S WEST and Frontier
upon completion of the mergers, and no person is authorized to make any use of
this joint proxy statement/prospectus in connection with any such resale.

     All shares of Qwest common stock received by U S WEST and Frontier
shareholders in the mergers will be freely transferable, except that shares of
Qwest common stock received by persons who are deemed to be "affiliates" of U
S WEST or Frontier under the Securities Act of 1933, as amended, at the time
of the U S WEST or Frontier meeting, as the case may be, may be resold by them
only in transactions permitted by Rule 145 under the 1933 Act or as otherwise
permitted under the 1933 Act. Persons who may be deemed to be affiliates of U
S WEST or Frontier for such purposes generally include individuals or entities
that control, are controlled by or are under common control with U S WEST or
Frontier, as the case may be, and include directors and executive officers of

U S WEST and Frontier. The merger agreements require that U S WEST and
Frontier use all reasonable efforts to cause each of such affiliates to
execute a written agreement to the effect that such persons will not offer,
sell or otherwise dispose of any of the shares of Qwest common stock issued to
them in the U S WEST or Frontier merger, as the case may be, in violation of
the 1933 Act or the related SEC rules.

     On June 11, 1999, the last full trading day before Qwest publicly
announced its merger proposals to U S WEST and Frontier, the last reported
closing prices per share of Qwest, U S WEST and Frontier stock were $44.875,
$54.875 and $55.4375, respectively. On June 18, 1999, the most recent
practicable date prior to the filing of this joint proxy statement/prospectus,
the last reported closing prices per share of Qwest, U S WEST and Frontier
stock were $37.9375, $58.0 and $58.3125, respectively. Stockholders are urged
to obtain current market quotations prior to making any decision with respect
to the mergers.

     The merger agreements do not permit Qwest, U S WEST and Frontier to
change their dividend policies before the mergers. The payment of dividends by
the combined company after the mergers, however, will depend on business
conditions, the combined company's financial condition and earnings, and other
factors.

(1)  The selected financial and operating data for the year ended as of
     December 31, 1998 include the effect of the acquisitions of LCI
     International, Inc., Icon CMT Corp., EUnet International Limited and
     Phoenix Network, Inc., which occurred during 1998. (See further
     discussion of these acquisitions in "Management's Discussion and Analysis
     of Financial Condition and Results of Operations" contained in the 1998
     Qwest Form 10-K.)

(2)  Qwest has not paid cash dividends on its Common Stock since becoming a
     public company in June 1997 and does not anticipate paying cash dividends
     in the foreseeable future.

(3)  EBITDA represents net earnings (loss) before interest, income tax expense
     (benefit), depreciation and amortization, a non-recurring expense of $2.6
     million in the year ended December 31, 1996, the non-recurring

     gain on sale of telecommunication agreements of $6.1 million in the year
     ended December 31, 1996, to restructure operations, a non-recurring gain
     on sale of contract rights of approximately $9.3 million in the year
     ended December 31, 1997, and non-recurring merger-related expenses of
     $846.5 million in the year ended December 31, 1998. 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, and may not be comparable with EBITDA as defined by
     other companies.

(1)  1998 income includes separation expenses of $68 ($0.13 per diluted share) associated with the Separation of Old U S
     WEST into two independent companies and an asset impairment charge of $21 ($0.04 per diluted share).  1997 income
     includes a $152 regulatory charge ($0.31 per diluted share) related primarily to the 1997 Washington State Supreme Court
     ruling that upheld a Washington rate order, a gain of $32 ($0.07 per diluted share) on the sale of an interest in Bell
     Communications Research, Inc. and a gain of $48 ($0.10 per diluted share) on the sales of local telephone exchanges.  1996
     income includes a gain of $36 ($0.07 per diluted share) on the sales of local telephone exchanges and the current effect of
     $15 ($0.03 per diluted share) from adopting Statement of Financial Accounting Standards ("FAS") No. 121, "Accounting
     for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of."  1995 income includes a gain of
     $85 ($0.18 per diluted share) on the sales of local telephone exchanges and costs of $8 ($0.02 per diluted share) associated

Chapter One - The Merger


     with the 1995 Recapitalization discussed in footnote 4 below. 1994
     income includes a gain of $51 ($0.11 per diluted share) on the sales of
     local telephone exchanges.

(2)  1997 net income was reduced by an extraordinary charge of $3 ($0.01per
     diluted share) for the early extinguishment of debt. 1996 net income
     includes a gain of $34 ($0.07 per diluted share) for the cumulative
     effect of the adoption of FAS No. 121. 1995 net income was reduced by an
     extraordinary item of $8 ($0.02per diluted share) for the early
     extinguishment of debt.

(3)  Pro forma income reflects the incremental interest expense associated
     with the Dex Indebtedness from the beginning of the period through the
     Separation Date. The pro forma earnings per diluted share amounts also
     reflect the issuance of approximately 16,341,000 shares of common stock
     (net of the redemption of approximately 305,000 fractional shares) issued
     in connection with the Dex Alignment as if the shares had been issued at
     the beginning of the period indicated.

(4)  The historical average shares outstanding assume a one-for-one conversion
     of historical Communications Group common shares outstanding into shares
     of U S WEST as of the Separation Date. The 1998 historical average common
     shares outstanding include the issuance of approximately 16,341,000
     shares of common stock (net of redemption of approximately 305,000
     fractional shares) issued in connection with the Dex Alignment. Effective
     November 1, 1995, each share of common stock of Old U S WEST was
     converted into one share each of Communications Stock and Media Stock
     (the "1995 Recapitalization"). Earnings per common share and dividends
     per common share for 1995 and 1994 have been presented on a pro forma
     basis to reflect the two classes of stock as if they had been outstanding
     since January 1, 1994.

(5)  1998 debt includes $3,900 of Dex Indebtedness.

                    UNAUDITED PRO FORMA CONDENSED COMBINED
                             FINANCIAL INFORMATION

The unaudited pro forma condensed combined financial information of Qwest
presented below is derived from the historical financial statements of Qwest,
U S WEST and Frontier. The unaudited pro forma condensed combined financial
information is presented under three separate merger scenarios: (1) a merger
between Qwest and U S WEST; (2) a merger between Qwest and Frontier; or (3) a
merger between Qwest, U S WEST and Frontier. The mergers with Frontier and U S
WEST are not dependent upon each other. Under all scenarios, the unaudited pro
forma condensed combined financial information was prepared using the purchase
method of accounting, with Qwest treated as the acquirer, as if the merger(s)
had been completed on January 1, 1998 for statement of operations purposes and
on March 31, 1999 for balance sheet purposes.

For a summary of the U S WEST merger agreement, see "The U S WEST Merger
Agreement". For a summary of the Frontier merger agreement, see "The Frontier
Merger Agreement".

The unaudited pro forma condensed combined financial information is based upon
the assumptions and adjustments described in the accompanying notes to the
unaudited pro forma condensed combined financial information presented on the
following pages. The assumptions and related pro forma adjustments have been
developed from information available to Qwest from the December 31, 1998 Form
10-K filings and March 31, 1999 Form 10-Q filings of Frontier and U S WEST.
Such pro forma adjustments have been included only to the extent known and
reasonably available to Qwest. Additional information may exist that could
materially affect the assumptions and pro forma adjustments. Such information
is not available to Qwest because it is within the peculiar knowledge of
Frontier and U S WEST. Furthermore, the determination of the fair value of
Qwest common stock to be issued has been estimated based upon the closing
market price of $37.94 on June 18, 1999. The final purchase consideration will
be based partly upon the average market price of the Qwest common stock for a
reasonable period of time before and after agreement is reached on the mergers
among Qwest, Frontier and U S WEST. As a result of these uncertainties, the
final determination and allocation of purchase price may differ from the
amounts assumed in this unaudited pro forma condensed combined financial
information and those differences may be material.

This unaudited pro forma condensed combined financial information should be
read in conjunction with the separate historical financial statements and
accompanying notes of Qwest, U S WEST and Frontier that are incorporated by
reference in this joint proxy statement/prospectus. You should not rely on the
unaudited pro forma condensed combined financial information as an indication
of the results of operations or financial position that would have been
achieved if the merger(s) had taken place earlier or of the results of
operations or financial position of Qwest after the completion of such
transactions.

     Notes to Unaudited Pro Forma Condensed Combined Financial Information

(1)  See "Description of Qwest--Unaudited Pro Forma Condensed Combined
     Financial Information."  The
     assumptions and related pro forma adjustments described below have been
     developed from information available to Qwest from the December 31, 1998
     Form 10-K and March 31, 1999 Form 10-Q filings of U S WEST. The pro forma
     adjustments described below have been included only to the extent known
     and reasonably available to Qwest. Additional information may exist that
     could materially affect the assumptions and related pro forma
     adjustments. Such information is not available to Qwest because it is
     within the peculiar knowledge of U S WEST.

(2)  Represents the allocation of the assumed purchase price to net tangible
     assets acquired and goodwill. The fair value of the consideration has
     been allocated to the net book value of the tangible assets and
     liabilities to be acquired based upon the amounts reported in the March
     31, 1999, unaudited consolidated condensed balance sheet of U S WEST
     because fair value information is not reasonably available to Qwest. The
     excess of the assumed consideration over the net book value of the
     tangible assets acquired has been allocated to goodwill because the
     existence of any identifiable intangible assets is the peculiar knowledge
     of U S WEST and is not reasonably known to Qwest. The purchase price and
     the excess of the purchase price over the net tangible assets acquired at
     March 31, 1999, are as follows (in millions):

     The value of the Qwest common stock to be issued is based upon
     approximately 876 million shares at a price of $37.94 per share (the
     closing market price on June 18, 1999). The purchase consideration will
     be based in part upon the average market price of the Qwest common stock
     for a reasonable period of time before and after agreement is reached
     between Qwest and U S WEST. The final determination of the purchase
     consideration may differ from the amount assumed in this unaudited pro
     forma condensed combined financial information and that difference may be
     material.

(3)  Qwest pays a fee to U S WEST for access to its network. The access cost
     is included in Qwest's operating expenses and U S WEST's revenues. The
     amounts included in the pro forma information have not been eliminated.
     The elimination of access cost and related revenues would not have an
     effect on the pro forma net earnings (loss). There are no other
     significant transactions between Qwest and U S WEST.

(4)  Reflects incremental amortization expense for the excess of the purchase
     price over the net tangible assets acquired. The excess of the purchase
     price over the net tangible assets acquired is being amortized over 40
     years, based upon Qwest's preliminary assessment of the business to be
     acquired.

(5)  The merger is expected to be a tax-free transaction to the shareholders
     of U S WEST. The purchase price has been allocated to the net tangible
     assets acquired based upon their carrying amounts included in the U S
     WEST March 31, 1999 Form 10-Q with the excess allocated to non-deductible
     goodwill. To the extent the final purchase price allocation creates a
     difference between the tax and financial reporting basis of assets and
     liabilities acquired, deferred income taxes and additional goodwill will
     be included in the pro forma unaudited condensed combined financial
     information.

(6)  Qwest pro forma earnings (loss) per share assumes the issuance of
     approximately 876 (884 million on a fully diluted basis) million shares
     at a price of $37.94 per share on January 1, 1998. The share price used
     is the closing share price on June 18, 1999 for Qwest common stock.

(7) Represents the elimination of the historical equity of U S WEST.

(8)  According to Schedule 14D-1 filed by U S WEST on May 21, 1999, U S WEST
     agreed to make a cash tender offer for approximately 9.5% of the
     outstanding Global Crossing common stock at a price of $62.75 per share
     (approximately $2.5 billion). The outcome of such tender offer has not
     been reflected in the pro forma financial information.

     Notes to Unaudited Pro Forma Condensed Combined Financial Information

(1)  See "Description of Qwest--Unaudited Pro Forma Condensed Combined
     Financial Information." The assumptions and related pro forma adjustments
     described below have been developed from information available to Qwest
     from the December 31, 1998 Form 10-K and March 31, 1999 Form 10-Q filings
     of Frontier. The pro forma adjustments described below have been included
     only to the extent known and reasonably available to Qwest. Additional
     information may exist that could materially affect the assumptions and
     related pro forma adjustments. Such information is not available to Qwest
     because it is within the peculiar knowledge of Frontier.

(2)  Represents the allocation of the assumed purchase price to net tangible
     assets acquired and goodwill. The fair value of the consideration has
     been allocated to the net book value of the tangible assets and
     liabilities (except for Frontier's 10.46% convertible debentures) to be
     acquired based upon the amounts reported in the March 31, 1999, unaudited
     consolidated condensed balance sheet of Frontier because fair value
     information is not reasonably available to Qwest. The 10.46% convertible
     debentures have been adjusted to fair value based upon the exchange ratio
     and Qwest's share price on June 18, 1999. The excess of the assumed
     consideration over the net book value of the tangible assets acquired has
     been allocated to goodwill because the existence of any identifiable
     intangible assets is the peculiar knowledge of Frontier and is not
     reasonably known to Qwest. The purchase price and the excess of the
     purchase price over the net tangible assets acquired at March 31, 1999,
     are as follows (in millions):

     The value of the Qwest common stock to be issued is based upon
     approximately 204 million shares at a price of $37.94 per share (the
     closing market price on June 18, 1999). The purchase consideration will
     be based in part upon the average market price of the Qwest common stock
     for a reasonable period of time before and after agreement is reached
     between Qwest and Frontier. The final determination of the purchase
     consideration may differ from the amount assumed in the unaudited pro
     forma condensed financial information and that difference may be
     material.

(3)  Represents assumed interest expense of $250 million annually ($62 million
     for the three months ended March 31, 1999) on the issuance of $3,700
     million of debt to fund the cash portion of the purchase consideration.

     Such interest expense was calculated at Qwest's approximate borrowing
     rate of 6.75 percent at March 31, 1999. A 1/8 percentage point change in
     the assumed financing rate would change interest expense by $5 million
     annually ($1 million for the three months ended March 31, 1999). Interest
     expense includes amortization of assumed debt issuance costs of $83
     million over the term of the debt.

(4)  Represents the elimination of revenues and cost of sales related to the
     sale of dark fiber along Qwest's communications network to Frontier.
     There are no other significant transactions between Qwest and Frontier.

(5)  Reflects incremental amortization expense for the excess of the purchase
     price over the net tangible assets acquired. The excess of the purchase
     price over the net tangible assets acquired is being amortized over 40
     years, based upon Qwest's preliminary assessment of the business to be
     acquired.

(6)  Reflects the estimated income tax effect of the pro forma adjustments
     based upon combined federal and state statutory rate of approximately
     40%. The merger is expected to be a tax-free transaction to the
     shareholders of Frontier (except for the cash paid to Frontier's
     shareholders). The purchase price has been allocated to the net tangible
     assets acquired based principally upon their carrying amounts included in
     the Frontier March 31, 1999 Form 10-Q with the excess allocated to
     non-deductible goodwill. To the extent the final purchase price
     allocation creates a difference between the tax and financial reporting
     basis of assets and liabilities acquired, deferred income taxes and
     additional goodwill will be included in the pro forma unaudited condensed
     combined financial information.

(7)  Qwest pro forma loss per share assumes the issuance of approximately 204
     million shares at a price of $37.94 per share on January 1, 1998. The
     share price used is the closing share price on June 18, 1999 for Qwest
     common stock.

(8) Represents the elimination of the historical equity of Frontier.

     Notes to Unaudited Pro Forma Condensed Combined Financial Information

(1)  See "Description of Qwest--Unaudited Pro Forma Condensed Combined
     Financial Information." The assumptions and related pro forma adjustments
     described below have been developed from information available to Qwest
     from the December 31, 1998 Form 10-K and March 31, 1999 Form 10-Q filings
     of Frontier and U S WEST. The pro forma adjustments described below have
     been included only to the extent known and reasonably available to Qwest.
     Additional information may exist that could materially affect the
     assumptions and related pro forma adjustments. Such information is not
     available to Qwest because it is within the peculiar knowledge of
     Frontier and U S WEST.

(2)  Represents the allocation of the assumed purchase price to net tangible
     assets acquired and goodwill. The fair value of the consideration has
     been allocated to the net book value of the tangible assets and
     liabilities (except for Frontier's 10.46% convertible debentures) to be
     acquired based upon the amounts reported in the March 31, 1999, unaudited
     consolidated condensed balance sheets of Frontier and U S WEST because
     fair value information is not reasonably available to Qwest. The 10.46%
     convertible debentures have been adjusted to fair value based upon the
     exchange ratio and Qwest's share price on June 18, 1999. The excess of
     the assumed consideration over the net book value of the tangible assets
     acquired has been allocated to goodwill because the existence of any
     identifiable intangible assets is the peculiar knowledge of Frontier and
     U S WEST and is not reasonably known to Qwest. The purchase price and the
     excess of the purchase price over the net tangible assets acquired at
     March 31, 1999, are as follows (in millions):

</TABLE>


     The value of the Qwest common stock to be issued is based upon
     approximately 1,111 million shares at a price of $37.94 per share (the
     closing market price on June 18, 1999). The purchase consideration will
     be based in part upon the average market price of the Qwest common stock
     for a reasonable period of time before and after agreement is reached
     between Qwest, Frontier and U S WEST. The final determination of the
     purchase consideration may differ from the amount assumed in the
     unaudited pro forma condensed financial information and that difference
     may be material.

(3)  Represents assumed interest expenses of $250 million annually ($62
     million for the three months ended March 31, 1999) on the issuance of
     $3,700 million of debt to fund the cash portion of the purchase
     consideration.

                                     I-43

Chapter One - The Merger


     Such interest expense was calculated at Qwest's approximate borrowing
     rate of 6.75 percent at March 31, 1999. A 1/8 percentage point change in
     the assumed financing rate would change interest expense by $5 million
     annual ($1 million for the three months ended March 31, 1999). Interest
     expense includes amortization of assumed debt issuance costs of $83
     million over the term of the debt.

(4)  Represents the elimination of revenues and cost of sales related to the
     sale of dark fiber along Qwest's communications network to Frontier.
     Furthermore, Qwest pays a fee to U S WEST for access to its network. The
     access cost is included in Qwest's operating expenses and U S WEST's
     revenues. The amounts included in the pro forma financial information have
     not been eliminated. The elimination of access cost and related revenues
     would not have an effect on the pro forma net earnings (loss). There are no
     other significant transactions between Qwest and U S WEST and Qwest and
     Frontier. Qwest is not aware whether or not there exists significant
     transactions between U S WEST and Frontier.

(5)  Reflects incremental amortization expense for the excess of the purchase
     price over the net tangible assets acquired. The excess of the purchase
     price over the net tangible assets acquired is being amortized over 40
     years, based upon Qwest's preliminary assessment of the businesses to be
     acquired.

(6)  Reflects the estimated income tax effect of the pro forma adjustments based
     upon combined federal and state statutory rate of approximately 40%. The
     merger is expected to be a tax-free transaction to the shareholders of U S
     WEST and Frontier (except for the cash portion paid to Frontier
     shareholders). The purchase price has been allocated to the net tangible
     assets acquired based upon their carrying amounts included in the U S WEST
     and Frontier March 31, 1999 Form 10-Qs with the excess allocated to
     non-deductible goodwill. To the extent the final purchase price allocation
     creates a difference between the tax and financial reporting basis of
     assets and liabilities acquired, deferred income taxes and additional
     goodwill will be included in the pro forma unaudited condensed combined
     financial information.

(7)  Qwest pro forma net earnings (loss) per share assumes the issuance of
     approximately 1,111 million shares (1,124 million shares on a fully
     diluted basis) at a price of $37.94 per share on January 1, 1998. The
     share price used is the closing share price on June 18, 1999 for Qwest
     common stock.

(8)  Represents the elimination of the historical equity of U S WEST and
     Frontier.

(9)  According to Schedule 14D-1 filed by U S WEST on May 21, 1999, U S WEST
     agreed to make a cash tender offer for approximately 9.5% of the
     outstanding Global Crossing common stock at a price of $62.75 per share
     (approximately $2.5 billion). The outcome of such tender offer has not
     been reflected in the pro forma financial information.

AS OF THE DATE OF FILING OF THIS JOINT PROXY STATEMENT/PROSPECTUS NO MERGER
AGREEMENT HAS BEEN EXECUTED BETWEEN QWEST AND U S WEST. THE FOLLOWING
DESCRIPTION DESCRIBES PROVISIONS IN QWEST'S MERGER PROPOSAL TO U S WEST THAT
WOULD OCCUR IF AND ONLY IF THE TRANSACTION PROPOSED BY QWEST TO U S WEST ON JUNE
13, 1999 WERE ACCEPTED IN ITS CURRENT FORM.



                          THE U S WEST MERGER AGREEMENT

     The following summary of the proposed U S WEST merger agreement is
qualified by reference to the complete text of the merger agreement, which is
incorporated by reference and attached as Annex __.

Structure of the Merger

     Under the merger agreement, U S WEST merger sub will merge into U S WEST
so that U S WEST becomes a wholly-owned subsidiary of Qwest.

Timing of Closing

     The closing will occur as soon as practicable after the day on which the
last of the conditions set forth in the merger agreement has been satisfied or
waived. We expect that, as promptly as practicable after the closing of the
merger, we will file a merger certificate with the Secretary of State of the
State of Delaware, at which time the merger will be effective.

Merger Consideration

     The merger agreement provides that each share of U S WEST common stock
outstanding immediately prior to the effective time will, at the effective
time, be converted into the right to receive [____] shares of Qwest common
stock. However, any shares of U S WEST common stock held by U S WEST as
treasury stock or owned by Qwest or any subsidiary of Qwest will be canceled
without any payment for those shares. Shares held in U S WEST's employee
pension and compensation plans will be deemed issued and outstanding and will
not be treated as treasury stock for this purpose.

Treatment of U S WEST Stock Options

     At the effective time, each outstanding option, warrant and other right
granted by U S WEST to purchase shares of U S WEST common stock will be
converted into an option, warrant or other right to acquire Qwest common stock
having the same terms and conditions as the U S WEST stock option, warrant or
right had before the effective time. The number of shares that the new Qwest
option, warrant or right will be exercisable for and the exercise price of the
new Qwest option, warrant or right will reflect the exchange ratio in the
merger.

                                      I-47

<PAGE>



Chapter One - The Merger


Exchange of Shares

     We will appoint an exchange agent to handle the exchange of U S WEST
stock certificates in the merger for Qwest stock and the payment of cash for
fractional shares of U S WEST stock. Soon after the effective time, the
exchange agent will send to each holder of U S WEST stock a letter of
transmittal for use in the exchange and instructions explaining how to
surrender U S WEST stock certificates to the exchange agent. Holders of U S
WEST stock that surrender their certificates to the exchange agent, together
with a properly completed letter of transmittal, will receive the appropriate
merger consideration. Holders of unexchanged shares of U S WEST stock will not
be entitled to receive any dividends or other distributions payable by Qwest
after the effective time until their certificates are surrendered.

     Qwest will not issue any fractional shares in the merger. Holders of U S
WEST common stock will receive a cash payment in the amount of the proceeds
from the sale of their fractional shares in the market.

Qwest Board

     Qwest has agreed to take the necessary corporate action so that, at the
effective time, U S WEST's Chairman of the Board and _____ directors
designated by U S WEST will become directors of Qwest. Qwest expects that, at
the effective time, U S WEST's Chairman of the Board will become Vice-Chairman
of the Qwest Board.

Certain Covenants

     Each of Qwest and U S WEST has undertaken certain covenants in the merger
agreement. The following summarizes the more significant of these covenants.

     No Solicitation. U S WEST and Qwest have agreed that they and their
subsidiaries and their officers, directors, employees and advisers will not
take action to solicit or encourage an offer for an alternative acquisition
transaction involving U S WEST or Qwest of a nature defined in the merger
agreement.

     Restricted actions include engaging in discussions or negotiations with
any potential bidder, or furnishing information relating to either party or
its subsidiaries to a potential bidder. These actions are permitted in
response to an unsolicited offer so long as such unsolicited offer is made
prior to the time that the U S WEST or Qwest stockholder approval as the case
may be, is obtained and so long as prior to doing so: o the U S WEST or Qwest
Board, as the case may be, determines in its good faith judgment that it is
necessary to do so to comply with its fiduciary duty to shareholders, after
receiving the advice of outside legal counsel, and o U S WEST or Qwest, as the
case may be, receives from such person an executed confidentiality agreement
with terms no less favorable to such party than those contained in the
existing confidentiality agreement between U S WEST and Qwest.

     Each of U S WEST and Qwest must keep the other reasonably informed of the
status and details of any offer.

     U S WEST Board's Covenant to Recommend. The U S WEST Board has agreed to
recommend the approval and adoption of the merger agreement to U S WEST's
shareholders. However, the U S WEST Board is permitted not to make, to
withdraw or to modify in a manner adverse to Qwest this recommendation if o
the U S WEST Board determines in its good faith judgment that the failure to
do so would result in a reasonable possibility that it would breach its
fiduciary duty to U S WEST shareholders under applicable law, after receiving
the advice of outside counsel, and o U S WEST's Board has given Qwest five
business days to enhance its offer to the extent necessary to permit U S
WEST's Board to recommend the transaction to its shareholders in compliance
with such fiduciary duty.

           liability insurance maintained by U S WEST and Qwest, respectively,
           (except that U S WEST may substitute policies which are, in the
           aggregate, no less advantageous to the insured in any material
           respect) with respect to claims arising from facts or events which
           occurred on or before the effective time; and

        o  U S WEST and Qwest shall indemnify the directors and officers of U
           S WEST and Qwest, respectively, to the fullest extent to which each

                                                        Chapter One - The Merger


      (a) The merger agreement may be terminated by mutual written consent of
Qwest and U S WEST; or

      (b) The merger agreement may be terminated by either Qwest or U S WEST
if:

           o  the merger has not been completed by ________, ____. However, that
              date becomes ________, ____ if the reason for not closing by
              ________, ____ is that the regulatory conditions specified in the
              merger agreement have not been satisfied by that date,

           o  Qwest or U S WEST shareholders fail to give the necessary approval
              at a duly held meeting,

           o  there is a permanent legal prohibition to closing the merger,

           o  the Board of the other party fails to recommend the merger or
              withdraws or modifies in any adverse manner its approval or
              recommendation of the merger, or recommends a superior offer, or

           o  (1) the other party breaches or fails to perform in any material
              respect any of its representations, warranties, covenants or other
              agreements in a manner that cannot be cured by ________, ____
              (with a possible extension to ________, ____) or (2) a condition
              to the terminating party's obligations to consummate the merger
              cannot be satisfied prior to ________, ____ (with a possible
              extension to ________, ____); or

      (c) The merger agreement may be terminated by either Qwest or U S WEST
     prior to approval by its stockholders if:

           o  the Board of the terminating party determines in good faith, in
              response to a superior alternative proposal and after advice from
              outside counsel, that the failure to terminate the merger
              agreement in order to accept the superior proposal would result in
              a reasonable likelihood that the Board would breach its fiduciary
              duties to its stockholders, and

           o  the terminating party has complied with the requirements
              associated with the receipt of such superior proposals as provided
              in the merger agreement.

     Neither Qwest or U S WEST can terminate the merger agreement for the
reasons described in the first bullet under paragraph (b) above if its failure
to fulfill in any material respect its obligations under the merger agreement
has resulted in the failure to complete the merger.

     If the merger agreement is validly terminated, the agreement will become
void without any liability on the part of any party unless such party is in
willful breach thereof. However, the provisions of the merger agreement
relating to expenses and termination fees, as well as the confidentiality
agreement entered into between Qwest and U S WEST, will continue in effect
notwithstanding termination of the merger agreement.

     Termination Fees Payable by U S WEST. U S WEST has agreed to pay Qwest a
cash amount equal to $850 million in any of the following circumstances:

                                      I-51

<PAGE>



Chapter One - The Merger


        o  U S WEST terminates the merger agreement as described in paragraph
           (c) under "--Right to Terminate" above;

        o  Qwest terminates the merger agreement because the U S WEST Board
           fails to recommend the merger to its stockholders or withdraws or
           modifies in any adverse manner its approval or recommendation of the
           merger, or recommends a superior offer;

        o  the merger agreement is terminated after the stockholders of U S WEST
           do not approve the merger, and prior to such termination the U S WEST
           Board failed to recommend the merger to its stockholders or withdrew
           or modified in any adverse manner its approval or recommendation of
           the merger, or recommended a superior proposal;

        o  the merger agreement is terminated because the stockholders of U S
           WEST do not approve the merger and:

        o  at any time prior to the stockholder vote there had been an offer or
           proposal for an alternative transaction and

        o  within 12 months of such termination, U S WEST enters into an
           agreement with any third party with respect to an alternative
           transaction; or

        o  Qwest terminates the merger agreement because U S WEST fails to use
           reasonable efforts to file the registration statement relating to the
           transaction or to promptly hold its stockholders' meeting.

     Termination Fees Payable by Qwest. Qwest has agreed to pay U S WEST a
cash amount equal to $850 million if the merger agreement is terminated under
exactly corresponding provisions as applied to U S WEST's payment of
termination fees, with the positions of the parties reversed.

     Reduction of Termination Fees Payable by U S WEST. If U S WEST is
required to pay a termination fee, the amount of the fee may be reduced by an
amount of up to $250 million equal to any amount U S WEST pays Qwest for
capacity on Qwest's systems.

Other Expenses

     Except as described in the merger agreement, all costs and expenses
incurred in connection with the merger agreement and related transactions will
be paid by the party incurring such costs or expenses. Certain expenses
incurred in connection with the printing of the joint proxy
statement/prospectus and certain filing fees will be shared equally by Qwest
and U S WEST.

Amendments and Waivers

     Amendments. Any provision of the merger agreement may be amended prior to
the effective time if the amendment is in writing and signed by Qwest and U S
WEST. After the approval of the merger agreement by the shareholders of either
Qwest or U S WEST, no amendment may be made which would:

        o  alter or change the amount or kinds of consideration to be received
           by the holders of U S WEST or Qwest common stock upon consummation of
           the merger;

Chapter One - The Merger


                        SEE CAUTIONARY NOTE ON COVER PAGE

     AS OF THE DATE OF FILING OF THIS JOINT PROXY STATEMENT/PROSPECTUS NO
MERGER AGREEMENT HAS BEEN EXECUTED BETWEEN QWEST AND FRONTIER. THE FOLLOWING
DESCRIPTION DESCRIBES PROVISIONS IN QWEST'S MERGER PROPOSAL TO FRONTIER THAT
WOULD OCCUR IF AND ONLY IF THE TRANSACTION PROPOSED BY QWEST TO FRONTIER ON
JUNE 13, 1999 WERE ACCEPTED IN ITS CURRENT FORM.


                          THE FRONTIER MERGER AGREEMENT

     The following summary of the Frontier merger agreement is qualified by
reference to the complete text of the merger agreement, which is incorporated
by reference and attached as Annex __.

Structure of the Merger

     Under the merger agreement, Qwest will form Frontier merger sub, a
wholly-owned subsidiary. Frontier will merge with and into Frontier merger
sub, leaving Frontier merger sub as the surviving entity.

Timing of Closing

     The closing will occur on the second business day after the day on which
the last of the conditions set forth in the merger agreement has been
satisfied or waived. We expect that, as promptly as practicable after the
closing of the merger, we will file a merger certificate with the New York
Department of State, at which time the merger will be effective.

Merger Consideration

     The merger agreement provides that each share of Frontier common stock
outstanding immediately prior to the effective time will, at the effective
time, be converted into o the right to receive [___] shares of Qwest common
stock and o $20 in cash. However, any shares of Frontier common stock held by
Frontier as treasury stock or owned by Qwest or any subsidiary of Qwest will
be canceled without any payment for those shares.

Treatment of Frontier Stock Options and Warrants

     Each Frontier stock option and warrant shall be deemed to constitute an
option to acquire or a warrant to acquire the number of shares of Qwest common
stock as the holder of each such Frontier stock option or warrant would have
been entitled to receive had such holder exercised such Frontier stock option
or warrant in full immediately prior to the effective time. The same terms and
conditions as were applicable under such Frontier stock option or warrant
shall apply to the stock options and warrants assumed by Qwest as
comprehensively set forth in the merger agreement.

                                                        Chapter One - The Merger


Exchange of Shares

     We will appoint an exchange agent to handle the exchange of Frontier
stock certificates in the merger for Qwest stock and the payment of cash for
fractional shares of Frontier stock. Soon after the effective time, the
exchange agent will send to each holder of Frontier stock a letter of
transmittal for use in the exchange and instructions explaining how to
surrender Frontier stock certificates to the exchange agent. Holders of
Frontier stock that surrender their certificates to the exchange agent,
together with a properly completed letter of transmittal, will receive the
appropriate merger consideration. Holders of unexchanged shares of Frontier
stock will not be entitled to receive any dividends or other distributions
payable by Qwest after the effective time until their certificates are
surrendered.

     Qwest will not issue any fractional shares in the merger. Holders of
Frontier common stock will receive a cash payment in the amount of the
proceeds from the sale of their fractional shares in the market.

Qwest Board

     Qwest has agreed to take the necessary corporate action so that, at the
effective time, [__] directors designated by Frontier will become directors of
Qwest.

Certain Covenants

     Each of Qwest and Frontier has undertaken certain covenants in the merger
agreement. The following summarizes the more significant of these covenants:

     No Solicitation by Frontier. Frontier has agreed that it and its
subsidiaries and their officers, directors, employees and advisers will not
take action to solicit or encourage an offer for an alternative transaction
involving Frontier of a nature defined in the merger agreement.

     Restricted actions include engaging in discussions or negotiations with
any potential bidder, or furnishing information relating to Frontier or its
subsidiaries to a potential bidder. These actions are permitted in response to
an unsolicited bona fide written proposal so long as such a proposal is made
prior to the time that Frontier stockholder approval is obtained and so long
as:

        o  prior to engaging in discussions or providing information to such
           potential bidder, the Frontier Board concludes in good faith that
           the proposal could reasonably be expected to constitute a superior
           proposal;

        o  prior to recommending the proposal or withdrawing/modifying its
           recommendation with respect to the transactions contemplated by the
           merger agreement, the Frontier Board concludes in good faith that
           the proposal would, if consummated, constitute a superior proposal;

        o  prior to providing any information or data to a potential bidder,
           such potential bidder enters into a confidentiality and standstill
           agreement similar to the Frontier/Qwest confidentiality and
           standstill agreement; and

        o  prior to providing any information to or entering into discussions
           with such potential bidder, Frontier promptly notifies Qwest of the
           proposal and discloses the potential bidder's identity.

     Frontier must keep Qwest informed, on a current basis, of the status and
terms of any proposal or offer and the status of any such discussions or
negotiations.

Chapter One - The Merger


     Frontier Board's Covenant to Recommend. The Frontier Board has agreed to
recommend the approval and adoption of the merger agreement to Frontier's
shareholders. However, the Frontier Board is permitted not to make, to
withdraw or to modify in a manner adverse to Qwest this recommendation if the
Frontier Board concludes in good faith that an unsolicited bona fide written
proposal submitted by a third party bidder would, if consummated, constitute a
superior proposal.

     Qwest Board's Covenant to Recommend. The Qwest Board has agreed to
recommend the approval of the merger agreement to Qwest's shareholders, but
has no obligation to call, give notice of, convene and hold a meeting of its
shareholders until such time as Frontier is obligated to do so with respect to
its shareholders.

     Interim Operations of Qwest and Frontier. Qwest and Frontier are required
to conduct their business in the ordinary course consistent with past practice
until the effective time and subject to certain exceptions, may not engage in
certain material transactions during this period such as material acquisitions
or dispositions and issuances or repurchases of stock.

     Additionally, Frontier may not, without first obtaining the written
consent of Qwest:

        o  incur capital expenditures, except in the ordinary course of
           business consistent with past practice (within certain aggregate
           dollar limits);

        o  incur indebtedness, except in connection with permitted
           acquisitions or arrangements in existence on ______________ for use
           in the ordinary course of business;

        o  pay or discharge indebtedness, other than indebtedness incurred in
           the ordinary course of business;

        o  increase the compensation of senior officers, increase any employee
           benefits or adopt any new benefit plan other than as permitted by
           the merger agreement or in the ordinary course of business;

        o  take any action to make its rights agreement dated as of April 9,
           1995 between Frontier and First National Bank of Boston
           inapplicable to any transaction other than a transaction that the
           Frontier Board has determined to be a superior proposal; or

        o  split, combine or reclassify any of its capital stock or exchange any
           other securities for its capital stock.

     Additionally, Qwest has agreed that prior to the closing it will not,
without the prior written consent of Frontier, enter into any business
combination, merger or similar transaction where its shareholders would
receive any consideration in exchange for their shares of Qwest common stock
unless the transaction will close after the closing of the merger agreement,
the transaction would not disqualify the Frontier merger as a reorganization
for tax purposes and the consideration paid to Qwest shareholders in the
transaction meets a minimum threshold.

     Best Efforts Covenant. Qwest and Frontier have agreed to cooperate with
each other and use their best efforts to take all actions and do all things
necessary or advisable under the merger agreement and applicable laws to
complete the merger and the other transactions contemplated by the merger
agreement.

     Employee Benefits Matters. Qwest agrees that the combined company will
maintain Frontier's employee benefits at current levels as well as certain
specified employee benefit plans (including a "change in control severance
plan") for two years after the effective time, and will provide $35 million in
retention bonuses to employees of Frontier below the level of Vice-President.

                                                        Chapter One - The Merger


     Indemnification and Insurance of Qwest and U S WEST Directors and
Officers. The merger agreement provides that the surviving corporation shall
cause to be maintained in effect in its certificate of incorporation and
by-laws:

        o  for a period of six years after the effective time, the current
           provisions regarding elimination of liability of directors and
           indemnification of officers, directors and employees; and

        o  for a period of six years, the current policies of directors' and
           officers' liability insurance and fiduciary liability insurance
           maintained by Frontier with respect to claims arising from facts or
           events that occurred on or before the effective time, so long as
           such policies are no less favorable than the Frontier policy in
           effect on the day the merger is effective, except that the
           surviving company will only be obligated to pay up to 200% of the
           annual premium paid by Frontier for such insurance as of the day
           the merger is effective.

     Voting Trust. Qwest and Frontier have agreed that, if at any time prior
to the Frontier meeting, a third party shall make an unsolicited offer to
acquire control of Frontier, which offer is not recommended by Frontier's
Board, then Qwest and Frontier will use their reasonable best efforts to
consummate the merger by implementing a "voting trust" or similar structure
permitting the merger prior to the receipt of all final regulatory approvals.

     Redemption of Frontier Preferred Stock. Prior to the Frontier meeting,
Frontier shall take all actions as are necessary to redeem all the Frontier
preferred stock then outstanding, using its own cash, and in compliance with
the applicable provisions as set forth in its restated certificate of
incorporation.

Representations and Warranties

     The merger agreement contains substantially reciprocal representations
and warranties made by Qwest and Frontier to each other. The most significant
of these relate to:

     o corporate authorization to enter into the contemplated transaction o
     the shareholder votes required to approve the contemplated transaction o
     governmental approvals required in connection with the contemplated
     transaction o absence of any breach of organizational documents, law or
     certain material agreements as a result of the contemplated transaction o
     capitalization o information provided by it for inclusion in this joint
     proxy statement/prospectus o financial statements o finders' or advisors'
     fees o absence of certain material changes since a specified balance
     sheet date o absence of undisclosed material liabilities o litigation o
     tax matters o employee benefits matters and o compliance with laws.

     In addition, Frontier represents and warrants to Qwest as to certain
other matters, including the inapplicability of Frontier's shareholder rights
plan to the merger.

     The representations and warranties in the merger agreement do not survive
the closing or termination of the merger agreement.

complete the merger are subject to the satisfaction or, to the extent legally
permissible, waiver of the following conditions:

Qwest and Frontier.

      (b) The merger agreement may be terminated by either Qwest or Frontier
if:

          o  the merger has not been completed by ______, ____. However, the
             merger agreement may not be terminated for this reason by either
             Qwest or Frontier if such party's failure to fulfill in any

      (d) The merger agreement may be terminated by Frontier at any time prior

          o  Frontier has paid Qwest the cash termination fee described under
             "--Termination Fees Payable by Frontier" below.

     If the merger agreement is validly terminated, the agreement will become
void without any liability on the part of any party unless such party is in
willful breach thereof. However, the provisions of the merger agreement

Frontier, will continue in effect notwithstanding termination of the merger
agreement.

           Frontier enters into an agreement for an alternative transaction, or
           consummates an alternative transaction, with any other third party;

        o  Qwest terminates the merger agreement because the merger was not
           consummated by the termination date or either Qwest or Frontier
           terminates the merger agreement because of the existence of a legal
           prohibition and the following three conditions are met:

        o  at any time after the date of the merger agreement and at or before

           Frontier intentionally breaches any of its material covenants or

Other Expenses

     Except as described in the merger agreement and subject to an exception

Amendments; Waivers

closing if the amendment or waiver is in writing and signed, in the case of an
amendment, by the respective Boards of each of the parties or, in the case of
a waiver, by the party against whom the waiver is to be effective. After the
approval of the merger agreement by the shareholders of Qwest and Frontier, no
amendment or waiver that by law requires further approval by shareholders may
be made without the further approval of such shareholders.

     proposals and (2) have the effect of a vote against in the case of the
     Qwest charter amendment proposal, the U S WEST merger proposal and the
     Frontier merger proposal.

     The extent to which these proxy soliciting efforts will be necessary
depends entirely upon how promptly proxies are submitted. You should send in
your proxy by mail, telephone or internet without delay. We also reimburse
brokers and other nominees for their expenses in sending these materials to
you and getting your voting instructions.

     Do not send in any stock certificates with your proxy cards. The exchange

certificates for U S WEST and Frontier common stock to former U S WEST and
Frontier shareholders as soon as practicable after the completion of the
applicable merger.

     We are not currently aware of any other business to be acted upon at

or act on those matters according to their best judgment, including to adjourn
the meeting.

     Adjournments may be made for the purpose of, among other things,
soliciting additional proxies. Any adjournment may be made from time to time
by approval of the holders of shares representing a majority of the votes
present in person or by proxy at the meeting, whether or not a quorum exists,
without further notice other than by an announcement made at the meeting. None
of us currently intends to seek an adjournment of our meeting.

                       DESCRIPTION OF QWEST CAPITAL STOCK

     The following summary of the terms of the capital stock of Qwest prior
to, and after completion of, the mergers is not meant to be complete and is
qualified by reference to the Qwest charter and Qwest by-laws. Copies of the
Qwest charter and Qwest by-laws are incorporated by reference and will be sent
to holders of shares of Qwest common stock, U S WEST common stock and Frontier
common stock upon request. See "Where You Can Find More Information".

Authorized Capital Stock

     Prior to Completion of the Mergers. Under the Qwest charter, Qwest's
authorized capital stock consists of 2.0 billion shares of Qwest common stock,
$.01 par value, and 25 million shares of preferred stock, $.01 par value.

     Following Completion of the Mergers. If the Qwest charter amendment
proposal is approved, the Qwest charter will be amended to increase the
authorized number of shares of Qwest common stock to ___ billion.

Qwest Common Stock

     Qwest Common Stock Outstanding. The outstanding shares of Qwest common
stock are, and the shares of Qwest common stock issued pursuant to the mergers
will be, duly authorized, validly issued, fully paid and nonassessable.

     Voting Rights. Each holder of Qwest common stock is entitled to one vote
for each share of Qwest common stock held of record on the applicable record
date on all matters submitted to a vote of shareholders.

     Dividend Rights; Rights upon Liquidation. The holders of Qwest common
stock are entitled to receive, from funds legally available for the payment
thereof, dividends when and as declared by resolution of the Qwest Board,
subject to any preferential dividend rights granted to the holders of any
outstanding Qwest preferred stock. In the event of liquidation, each share of
Qwest common stock is entitled to share pro rata in any distribution of
Qwest's assets after payment or providing for the payment of liabilities and
the liquidation preference of any outstanding Qwest preferred stock.

     Preemptive Rights. Holders of Qwest common stock have no preemptive
rights to purchase, subscribe for or otherwise acquire any unissued or
treasury shares or other securities.

Qwest Preferred Stock

     Qwest Preferred Stock Outstanding. As of [______], 1999, no shares of Qwest
preferred stock were issued and outstanding.

     Blank Check Preferred Stock. Under the Qwest charter, the Qwest Board has
the authority, without shareholder approval, to create one or more classes or
series within a class of preferred stock, to issue shares of preferred stock
in such class or series up to the maximum number of shares of the relevant
class or series of preferred stock authorized, and to determine the
preferences, rights, privileges and restrictions of any such class or series,
including the dividend rights, voting rights, the rights and terms of
redemption, the rights and terms of conversion, liquidation preferences, the
number of shares constituting any such class or series and the designation of
such class or series. Acting under this authority, the Qwest Board could
create and issue a class or series of preferred stock with rights, privileges
or restrictions, and adopt a shareholder rights plan, having the effect of

                                      III-5

Chapter Three - Certain Legal Information


discriminating against an existing or prospective holder of securities as a
result of such shareholder beneficially owning or commencing a tender offer
for a substantial amount of Qwest common stock. One of the effects of
authorized but unissued and unreserved shares of capital stock may be to
render more difficult or discourage an attempt by a potential acquiror to
obtain control of Qwest by means of a merger, tender offer, proxy contest or
otherwise, and thereby protect the continuity of Qwest's management. The
issuance of such shares of capital stock may have the effect of delaying,
deferring or preventing a change in control of Qwest without any further
action by the shareholders of Qwest. Qwest has no present intention to adopt a
shareholder rights plan, but could do so without shareholder approval at any
future time.

Amendment of the Qwest Charter

     At the Qwest meeting, holders of Qwest common stock will be asked to
approve the amendment of the Qwest charter. The amendment will increase the
number of authorized shares of Qwest common stock to [ ] billion. Approval of
the merger proposals is conditioned on approval of the Qwest charter amendment
proposal. However, approval of the Qwest charter amendment proposal is not
conditioned on approval of the merger proposals.

     Increase of Authorized Common Stock. Qwest's charter currently authorizes
2.0 billion shares of common stock and 25 million shares of preferred stock.
On ________, 1999, _____________ shares of Qwest common stock were issued and
outstanding.

     To complete the U S WEST merger, Qwest expects that approximately ___
billion shares of Qwest common stock will be required to be issued to holders
of U S WEST common stock and that approximately ___ million shares of Qwest
common stock will be required to be reserved for issuance under U S WEST
employee stock options and other stock-based awards.

     To complete the Frontier merger, Qwest expects that approximately ___
billion shares of Qwest common stock will be required to be issued to holders
of Frontier common stock and that approximately ____ million shares of Qwest
common stock will be required to be reserved for issuance under Frontier
employee stock options and other stock-based awards.

     As these numbers show, the 2.0 billion shares of common stock currently
authorized under the Qwest charter will not be sufficient to complete the
mergers. We therefore ask Qwest shareholders to approve the amendment, which
will change Article FOURTH of the Qwest charter to increase the number of
authorized shares of Qwest common stock from 2.0 billion to ___ billion.

     The increased number of authorized shares will give Qwest sufficient
shares to complete the mergers. At present, Qwest has no plans to issue shares
of Qwest common stock for any other purpose. However, we believe it is
desirable to have additional shares available for other corporate purposes
that might arise in the future. For example, although Qwest currently meets
its obligations to deliver shares under employee stock options and similar
arrangements with treasury shares (meaning previously issued shares that have
been reacquired by Qwest), it may become desirable in the future to use newly
issued shares for this purpose. Shares could also be used for acquisitions or
to raise capital. Under some circumstances, it is also possible for a company
to use unissued shares for antitakeover purposes, but Qwest has no present
intention to take any such action.

     Whether or not any future issuance of shares unrelated to the mergers
would be submitted for a shareholder vote depends upon the nature of the
issuance, legal and stock exchange requirements, and the judgment of the Qwest
Board at the time.

                INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

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

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

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

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

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

     These forward-looking statements are subject to numerous assumptions,
risks and uncertainties that may cause Qwest's actual results to be materially
different from any future results expressed or implied by Qwest in those
statements. The risks and uncertainties include those risks, uncertainties and
risk factors identified, among other places, under "Risk Factors" in this
document, and under "Management's Discussion and Analysis of Financial
Condition and Results of Operations" in the Annual Report on Form 10-K for the
year ended December 31, 1998.

     The most important facts that could prevent Qwest from achieving its
stated goals include, but are not limited to, the following:

     o  Qwest's failure to construct its communications network on schedule and
        on budget;

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

     o  potential fluctuation in quarterly results;

                                     III-7

Chapter Three - Certain Legal Information


     o  volatility of stock price;

     o  intense competition in the communications services market;

     o  dependence on new product development;

     o  Qwest's ability to achieve year 2000 compliance;

     o  rapid and significant changes in technology and markets;

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

     o  failure to maintain necessary rights of way.

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

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


                                  LEGAL MATTERS

     The validity of the Qwest common stock to be issued to U S WEST and
Frontier shareholders in the mergers will be passed upon by counsel to Qwest.
It is a condition to the completion of the U S WEST merger that Qwest and U S
WEST receive an opinion from their counsel with respect to the tax treatment
of the U S WEST merger. It is a condition to the completion of the Frontier
merger that Qwest and Frontier receive an opinion from their counsel with
respect to the tax treatment of the Frontier merger.

connection with such action if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of Qwest,

consummation of the U S WEST merger. In addition, U S WEST and Qwest shall
indemnify the directors and officers of U S WEST and Qwest, respectively, to

liability of directors and indemnification of officers, directors and employees

liability insurance maintained by Frontier (except that Qwest may substitute
policies which are, in the aggregate, no less advantageous to the insured) with
respect to claims arising from facts or events that occurred on or before the
consummation of the Frontier merger.

     The Frontier merger agreement also provides that for a period of six years
after the closing, Qwest will provide directors' and officers' liability
insurance covering acts or omissions occurring prior to closing by each person
currently covered by Frontier's officers' and directors' liability insurance

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

                      (iii) To include any material information with respect to

          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 of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered

                                     S4-II-7

     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) 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), 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.

      (5) That every prospectus (i) that is filed pursuant to paragraph (4)
     immediately preceding, or (ii) that purports to meet the requirements of
     Section 10(a)(3) of the Securities Act of 1933 and is used in connection
     with an offering of securities subject to Rule 415, 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 of 1933, 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.

      (6) That, for purposes of determining any liability under the Securities
     Act of 1933, 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.

      (7) To respond to requests for information that is incorporated by
     reference into the Joint Proxy Statement/Prospectus pursuant to Item 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.

      (8) 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.

      (b) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 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
proceeding) is 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
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
