     The undersigned acknowledges that he or she has received the prospectus
dated          , 2001 (the "Prospectus") of Qwest Capital Funding, Inc. (the
"Company") and Qwest Communications International Inc. ("Qwest"), and this
Letter of Transmittal and the instructions hereto (the "Letter of Transmittal"),
which together constitute the Company's offer (the "Exchange Offer") to exchange

and 7 5/8% Notes due 2021 (collectively, the "new
<PAGE>

Notes") the offering of which has been registered under the Securities Act of
1933, as amended (the "Securities Act"), pursuant to a Registration Statement of
which the Prospectus is a part, for each $1,000 principal amount of its
outstanding 5 7/8% Notes due 2004, 7% Notes due 2009 and 7 5/8% Notes due 2021,
respectively, (collectively, the "old Notes"), of which $3,750,000,000 aggregate
principal amount is outstanding, upon the terms and subject to the conditions
set forth in the Prospectus. The term "Expiration Date" will mean 5:00 p.m., New
York City time, on           , 2001, unless the Company, in its sole discretion,
extends the Exchange Offer, in which case the term will mean the latest date and
time to which the Exchange Offer is extended by the Company. Capitalized terms
used but not defined herein have the meaning given to them in the Prospectus.

     This Letter of Transmittal is to be used if: (1) certificates representing
old Notes are to be physically delivered to the Exchange Agent herewith by
Holders (as defined below); (2) tender of old Notes is to be made by book-entry
transfer to an account maintained by the Exchange Agent at The Depository Trust
Company ("DTC"), pursuant to the procedures set forth in "The Exchange
Offer -- Procedures for Tendering Old Notes" in the Prospectus by any financial

are registered on the books of the Company or any other person who has obtained
a properly completed bond power from the registered holder.

     All Holders of old Notes who wish to tender their old Notes must, before

or a facsimile thereof, to the Exchange Agent, in person or to the address set
forth above; and (2) tender (and not withdraw) his or her old Notes or, if a
tender of old Notes is to be made by book-entry transfer to the account
maintained by the Exchange Agent at DTC, confirm such book-entry transfer (a
"Book-Entry Confirmation"), in each case in accordance with the procedures for
tendering described in the Instructions to this Letter of Transmittal. Holders
of old Notes whose certificates are not immediately available, or who are unable
to deliver their certificates or Book-Entry Confirmation and all other documents
required by this Letter of Transmittal to be delivered to the Exchange Agent on
or before the Expiration Date, must tender their old Notes according to the
guaranteed delivery procedures set forth under the caption "The Exchange
Offer -- Guaranteed Delivery Procedures" in the Prospectus. (See Instruction 2.)

     Upon the terms and subject to the conditions of the Exchange Offer, the
acceptance for exchange of the old Notes validly tendered and not withdrawn and
the issuance of the new Notes will be made promptly following the Expiration
Date. For the purposes of the Exchange Offer, the Company will be deemed to have
accepted for exchange validly tendered old Notes when, as and if the Company has
given written notice thereof to the Exchange Agent.

     The undersigned has completed, executed and delivered this Letter of
Transmittal to indicate the action the undersigned desires to take with respect
to the Exchange Offer.

                    NOTE: SIGNATURES MUST BE PROVIDED BELOW
                PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to the Company the principal amount of old Notes indicated above.

     Subject to and effective upon the acceptance for exchange of the principal
amount of old Notes tendered hereby in accordance with this Letter of
Transmittal, the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right, title and interest in and to the old Notes tendered
hereby. The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent as its agent and attorney-in-fact (with full knowledge that the Exchange
Agent also acts as the agent of the Company and as Trustee under the Indenture
for the old Notes and the new Notes) with respect to the tendered old Notes with
full power of substitution (such power of attorney being deemed an irrevocable
power coupled with an interest), subject only to the right of withdrawal
described in the Prospectus, to (1) deliver certificates for such old Notes to
the Company or transfer ownership of such old Notes on the account books
maintained by DTC, together, in either such case, with all accompanying
evidences of transfer and authenticity to, or upon the order of, the Company and
(2) present such old Notes for transfer on the books of the Company and receive
all benefits and otherwise exercise all rights of beneficial ownership of such
old Notes, all in accordance with the terms of the Exchange Offer.

     The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretative advice given by the staff of the SEC to third
parties in connection with transactions similar to the Exchange Offer, so that
the new Notes issued pursuant to the Exchange Offer in exchange for the old
Notes may be offered for resale, resold and otherwise transferred by holders
thereof (other than a broker-dealer who purchased such old Notes directly from
the Company for resale pursuant to Rule 144A, Regulation S or any other
available exemption under the Securities Act or a person that is an "affiliate"
of the Company or Qwest within the meaning of Rule 405 under the Securities Act)
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such new Notes are acquired in the ordinary
course of such holders' business and such holders are not participating, do not
intend to participate and have no arrangement or understanding with any person
to participate, in the distribution of such new Notes.

     The undersigned represents and warrants that: (1) the new Notes acquired
pursuant to the Exchange Offer are being acquired in the ordinary course of
business of the person receiving new Notes (which will be the undersigned unless
otherwise indicated in the box entitled "Special Delivery Instructions" above)
(the "Recipient"); (2) neither the undersigned nor the Recipient (if different)
is engaged in, intends to engage in or has any arrangement or understanding with
any person to participate in the distribution (as that term is interpreted by
the SEC) of such new Notes; and (3) neither the undersigned nor the Recipient
(if different) is an "affiliate" of the Company or of Qwest as defined in Rule
405 under the Securities Act, or if it is an affiliate, it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable.

     If the undersigned is a broker-dealer, the undersigned further: (1)
represents that it acquired old Notes for the undersigned's own account as a
result of market-making activities or other trading activities; (2) represents
that it has not entered into any arrangement or understanding with the Company
or Qwest or any "affiliate" of the Company or Qwest (within the meaning of Rule
405 under the Securities Act) to distribute the new Notes to be received in the
Exchange Offer; and (3) acknowledges that it will deliver a prospectus meeting
the requirements of the Securities Act (for which purposes, the delivery of the
Prospectus, as the same may be hereafter supplemented or amended, will be
sufficient) in connection with any resale of new Notes received in the Exchange
Offer. Such a broker-dealer will not be deemed, solely by reason of such
acknowledgment and prospectus delivery, to admit that it is an "underwriter"
within the meaning of the Securities Act.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the old Notes
tendered hereby and to acquire new Notes issuable upon

                                        5
<PAGE>

the exchange of such tendered old Notes, and that, when the same are accepted
for exchange, the Company will acquire good and unencumbered title thereto, free
and clear of all liens, restrictions, charges and encumbrances and not subject
to any adverse claim. The undersigned also warrants that it will, upon request,
execute and deliver any additional documents deemed to be necessary or desirable
by the Exchange Agent or the Company in order to complete the exchange,
assignment and transfer of tendered old Notes or transfer of ownership of such
old Notes on the account books maintained by a book-entry transfer facility.

     The undersigned agrees that acceptance of any tendered old Notes by the
Company and the issuance of new Notes in exchange therefor will constitute
performance in full by the Company of its obligations under the Registration
Rights Agreement (as defined in the Prospectus) and that, upon the issuance of
the new Notes, the Company will have no further obligations or liabilities
thereunder for the registration of the old Notes or the new Notes.

     The undersigned understands that tenders of old Notes pursuant to the
procedures described under the caption "The Exchange Offer -- Procedures for
Tendering Old Notes" in the Prospectus and in the instructions hereto will
constitute a binding agreement between the undersigned, the Company and the
Exchange Agent in accordance with the terms and subject to the conditions of the
Exchange Offer.

     The Exchange Offer is subject to certain conditions set forth in the
Prospectus under the caption "The Exchange Offer -- Conditions of the Exchange
Offer." The undersigned recognizes that as a result of these conditions, as more
particularly set forth in the Prospectus, the Company may not be required to
exchange any of the old Notes tendered hereby. If any tendered old Notes are not
accepted for exchange pursuant to the Exchange Offer for any reason,
certificates for any such unaccepted old Notes will be returned (except as noted
below with respect to lenders through DTC), at the Company's cost and expense,
to the undersigned at the address shown below or at a different address as may
be indicated herein under "Special Delivery Instructions" as promptly as
practicable after the Expiration Date.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal will survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal will be binding on the undersigned's heirs, personal
representatives, successors and assigns. This tender may be withdrawn only in
accordance with the procedures set forth in this Letter of Transmittal.

     By acceptance of the Exchange Offer, each broker-dealer that receives new
Notes pursuant to the Exchange Offer hereby acknowledges and agrees that upon
the receipt of notice by the Company of the happening of any event that makes
any statement in the Prospectus untrue in any material respect or that requires
the making of any changes in the Prospectus in order to make the statements
therein not misleading (which notice the Company agrees to deliver promptly to
such broker-dealer), such broker-dealer will suspend use of the Prospectus until
the Company has amended or supplemented the Prospectus to correct such
misstatement or omission and has furnished copies of the amended or supplemented
prospectus to such broker-dealer.

     Unless otherwise indicated under "Special Registration Instructions,"
please issue the certificates representing the new Notes issued in exchange for
the old Notes accepted for exchange and return any certificates for old Notes
not tendered or not exchanged, in the name(s) of the undersigned (or, in either
such event in the case of old Notes tendered by DTC, by credit to the account at
DTC). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please send the certificates representing the new Notes issued in
exchange for the old Notes accepted for exchange and any certificates for old
Notes not tendered or not exchanged (and accompanying documents, as appropriate)
to the undersigned at the address shown below the undersigned's signature(s),
unless, in either event, tender is being made through DTC. If both "Special
Registration Instructions" and "Special Delivery Instructions" are completed,
please issue the certificates representing the new Notes issued in exchange for
the old Notes accepted for exchange in the name(s) of, and return any
certificates for old Notes not tendered or not exchanged to, the person(s) so
indicated. The undersigned understands that the Company has no obligations
pursuant to the "Special Registration Instructions" or "Special Delivery
Instructions" to transfer any old Notes from the name of the registered
Holder(s) thereof if the Company does not accept for exchange any of the old
Notes so tendered.

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1.  GUARANTEE OF SIGNATURES

     Signatures on this Letter of Transmittal need not be guaranteed if (a) this
Letter of Transmittal is signed by the registered holder(s) of the old Notes
tendered herewith and such holder(s) have not completed the box set forth herein
entitled "Special Registration Instructions" or the box entitled "Special
Delivery Instructions" or (b) such old Notes are tendered for the account of a
member firm of a registered national securities exchange or of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
having an office or correspondent in the United States (each, an "Eligible
Institution"). (See Instruction 6.) Otherwise, all signatures on this Letter of
Transmittal or a notice of withdrawal, as the case may be, must be guaranteed by
an Eligible Institution. All signatures on bond powers and endorsements on
certificates must also be guaranteed by an Eligible Institution.

2.  DELIVERY OF THIS LETTER OF TRANSMITTAL AND OLD NOTES

     Unless the Exchange Agent has received a properly transmitted Agent's
Message (as defined below), certificates for all physically delivered old Notes
or confirmation of any book-entry transfer to the Exchange Agent at DTC of old
Notes tendered by book-entry transfer, as well as, in each case (including cases
where tender is effected by book-entry transfer), a properly completed and duly
executed copy of this Letter of Transmittal or facsimile hereof and any other
documents required by this Letter of Transmittal, must be received by the
Exchange Agent at its address set forth herein before 5:00 p.m., New York City
time, on the Expiration Date. The method of delivery of the tendered old Notes,
this Letter of Transmittal and all other required documents to the Exchange
Agent is at the election and risk of the Holder and the delivery will be deemed
made only when actually received by the Exchange Agent. If old Notes are sent by
mail, registered mail with return receipt requested, properly insured, is
recommended. In all cases, sufficient time should be allowed to ensure timely
delivery. No Letter of Transmittal or old Notes should be sent to the Company.

     The Exchange Agent will make a request to establish an account with respect
to the old Notes at DTC for purposes of the Exchange Offer within two business
days after the date of the Prospectus, and any financial institution that is a
participant in DTC may make book-entry delivery of old Notes by causing DTC to
transfer such old Notes into the appropriate Exchange Agent's account at DTC in
accordance with DTC's procedures for transfer. However, although delivery of old
Notes may be effected through book-entry transfer at DTC, the Letter of
Transmittal, with any required signature guarantees or an Agent's Message (as
defined in the next paragraph) in connection with a book-entry transfer and any
other required documents, must, in any case, be transmitted to and received by
the Exchange Agent at the address specified on the cover page of the Letter of
Transmittal on or before the Expiration Date or the guaranteed delivery
procedures described below must be complied with.

     A Holder may tender old Notes that are held through DTC by transmitting its
acceptance through DTC's Automated Tender Offer Program, for which the
transaction will be eligible, and DTC will then edit and verify the acceptance
and send an Agent's Message to the Exchange Agent for its acceptance. The term
"Agent's Message" means a message transmitted by DTC to, and received by, the
Exchange Agent and forming part of the Book-Entry Confirmation, which states
that DTC has received an express acknowledgment from each participant in DTC
tendering the old Notes and that such participant has received the Letter of
Transmittal and agrees to be bound by the terms of the Letter of Transmittal and
the Company may enforce such agreement against such participant.

     Holders who wish to tender their old Notes and (1) whose old Notes are not
immediately available, or (2) who cannot deliver their old Notes, this Letter of
Transmittal or any other documents required hereby to the Exchange Agent on or
before the Expiration Date or comply with book-entry transfer procedures on a
timely basis must tender their old Notes according to the guaranteed delivery
procedures set forth in the Prospectus. See "The Exchange Offer -- Guaranteed
Delivery Procedures." Pursuant to such procedure: (1) such tender must be made
by or through an Eligible Institution and (2) on or before the Expiration Date,

                                        10
<PAGE>

the Exchange Agent must have received from the Eligible Institution either (a)
an Agent's Message with respect to guaranteed delivery or (b) a properly
completed and duly executed Notice of Guaranteed Delivery (by facsimile
transmission, overnight courier, mail or hand delivery) setting forth the name
and address of the Holder of the old Notes, the certificate number or numbers of
such old Notes and the principal amount of old Notes tendered, stating that the
tender is being made thereby and guaranteeing that, within five New York Stock
Exchange trading days after the date of signing of the Notice of Guaranteed
Delivery, this Letter of Transmittal (or facsimile hereof) together with the
certificate(s) representing the old Notes and any other required documents will
be deposited by the Eligible Institution with the Exchange Agent. Such properly
completed and executed Letter of Transmittal (or facsimile hereof), as well as
all other documents required by this Letter of Transmittal and the
certificate(s) representing all tendered old Notes in proper form for transfer
(or a confirmation of book-entry transfer of such old Notes into the Exchange
Agent's account at DTC), must be received by the Exchange Agent within five New
York Stock Exchange trading days after the date of signing of the Notice of
Guaranteed Delivery, all in the manner provided in the Prospectus under the
caption "The Exchange Offer -- Guaranteed Delivery Procedures." Any Holder who
wishes to tender his or her old Notes pursuant to the guaranteed delivery
procedures described above must ensure that the Exchange Agent receives the
Notice of Guaranteed Delivery before 5:00 p.m., New York City time, on the
Expiration Date. Upon request to the Exchange Agent, a Notice of Guaranteed
Delivery will be sent to Holders who wish to tender their old Notes according to
the guaranteed delivery procedures set forth above.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered old Notes, and withdrawal of tendered old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding. All tendering Holders, by execution of this Letter of
Transmittal (or facsimile thereof), will waive any right to receive notice of
the acceptance of the old Notes for exchange. The Company reserves the absolute
right to reject any and all old Notes not properly tendered or any old Notes the
Company's acceptance of which might, in the Company's judgment or the judgment
of the Company's counsel, be unlawful. The Company also reserves the right to
waive any irregularities or conditions of the Exchange Offer as to particular
old Notes. The Company's interpretation of the terms and conditions of the
Exchange Offer (including the instructions in this Letter of Transmittal) will
be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of old Notes must be cured within such
time as the Company will determine, Neither the Company, the Exchange Agent nor
any other person will be under any duty to give notification of defects or
irregularities with respect to tenders of old Notes, nor will any of them incur
any liability for failure to give such notification. Tenders of old Notes, will
not be deemed to have been made until such defects or irregularities have been
cured to the Company's satisfaction or waived. Any old Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering Holders pursuant to the Company's determination, unless
otherwise provided in this Letter of Transmittal, as soon as practicable
following the Expiration Date. The Exchange Agent and has no fiduciary duties to
the Holders with respect to the Exchange Offer and is acting solely on the basis
of directions of the Company.

3.  INADEQUATE SPACE

     If the space provided is inadequate, the certificate numbers and/or the
number of old Notes should be listed on a separate signed schedule attached
hereto.

4.  TENDER BY HOLDER

     Only a Holder of old Notes may tender such old Notes in the Exchange Offer.
Any beneficial owner of old Notes who is not the registered Holder and who
wishes to tender should arrange with such registered Holder to execute and
deliver this Letter of Transmittal on such beneficial owner's behalf or must,
before completing and executing this Letter of Transmittal and delivering his or
her old Notes, either make appropriate arrangements to register ownership of the
old Notes in such beneficial owner's name or obtain a properly complete bond
power from the registered Holder or properly endorsed certificates representing
such old Notes.

                                        11
<PAGE>

5.  PARTIAL TENDERS; WITHDRAWALS

     Tenders of old Notes will be accepted only in integral multiples of $1,000.
If less than the entire principal amount of any old Notes is tendered, the
tendering Holder should fill in the principal amount tendered in the third
column (B) of the box entitled "Description of 5 7/8% Notes due 2004,
Description of 7% Notes due 2009 and Description of 7 5/8% Notes due 2021"
above. The entire principal amount of any old Notes delivered to the Exchange
Agent will be deemed to have been tendered unless otherwise indicated. If the
entire principal amount of all old Notes is not tendered, then old Notes for the
principal amount of old Notes not tendered and a certificate or certificates
representing new Notes issued in exchange for any old Notes accepted will be
sent to the Holder at his or her registered address, unless a different address
is provided in the "Special Delivery Instructions" box above on this Letter of
Transmittal or unless tender is made through DTC, promptly after the old Notes
are accepted for exchange.

     Except as otherwise provided herein, tenders of old Notes may be withdrawn
at any time before 5:00 p.m., New York City time, on the Expiration Date. To
withdraw a tender of old Notes in the Exchange Offer, a written notice (sent by
facsimile transmission, mail or hand delivery) of withdrawal must be received by
the Exchange Agent at its address set forth herein before 5:00 p.m., New York
City time, on the Expiration Date. Any such notice of withdrawal must: (1)
specify the name of the person having deposited the old Notes to be withdrawn
(the "Depositor"); (2) identify the old Notes to be withdrawn (including the
certificate number or numbers and principal amount of such old Notes, or, in the
case of old Notes transferred by book-entry transfer, the name and number of the
account at DTC to be credited); (3) be signed by the Depositor in the same
manner as the original signature on the Letter of Transmittal by which such old
Notes were tendered (including any required signature guarantees) or be
accompanied by documents of transfer sufficient to have the Exchange Agent with
respect to the old Notes register the transfer of such old Notes into the name
of the person withdrawing the tender; (4) specify the name in which any such old
Notes are to be registered, if different from that of the Depositor; and (5)
state that the Depositor is withdrawing the election to have such old Notes
tendered. All questions as to the validity, form and eligibility (including time
of receipt) of such notices will be determined by the Company, whose
determination will be final and binding on all parties. Any old Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no new Notes will be issued with respect thereto unless the
old Notes so withdrawn are validly retendered. Any old Notes that have been
tendered but that are not accepted for exchange by the Company will be returned
to the Holder thereof without cost to such Holder as soon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. In the
case of old Notes tendered by book-entry transfer into the Exchange Agent's
account at DTC, the old Notes will be credited to an account with DTC specified
by the Holder. Properly withdrawn old Notes may be retendered by following one
of the procedures described in the Prospectus under "The Exchange
Offer -- Procedures for Tendering Old Notes" at any time before the Expiration
Date.

6.  SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder(s) of the old Notes tendered hereby, the signature must
correspond with the name(s) as written on the face of the Old Note without
alteration, enlargement or any change whatsoever. If any of the old Notes
tendered hereby are owned of record by two or more joint owners, all such owners
must sign this Letter of Transmittal.

     If a number of old Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many copies of this Letter of
Transmittal as there are different registrations of old Notes.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders (which term, for the purposes described herein,
will include a book-entry transfer facility whose name appears on a security
listing as the owner of the old Notes) of old Notes tendered and the certificate
or certificates for new Notes issued in exchange therefor is to be issued (or
any untendered principal amount of old Notes to be reissued) to the registered
Holder, then such Holder need not and should not endorse any tendered old Notes,
nor provide a separate bond power. In any other case, such Holder must either
properly endorse the old Notes

                                        12
<PAGE>

tendered or transmit a properly completed separate bond power with this Letter
of Transmittal with the signatures on the endorsement or bond power guaranteed
by an Eligible Institution.

     If this Letter of Transmittal (or facsimile hereof) is signed by a person
other than the registered Holder or Holders of any old Notes listed, such old
Notes must be endorsed or accompanied by appropriate bond powers in each case
signed as the name of the registered Holder or Holders appears on the old Notes.

     If this Letter of Transmittal (or facsimile hereof) or any old Notes or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or officers of corporations or others acting in a fiduciary
or representative capacity, such persons should so indicate when signing, and
unless waived by the Company, evidence satisfactory to the Company of their
authority so to act must be submitted with this Letter of Transmittal.

     Endorsement on old Notes or signatures on bond powers required by this
Instruction 6 must be guaranteed by an Eligible Institution.

7.  SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS

     Tendering Holders should indicate, in the applicable box or boxes, the name
and address to which new Notes or substitute old Notes for principal amounts not
tendered or not accepted for exchange are to be issued or sent, if different
from the name and address of the person signing this Letter of Transmittal. In
the case of issuance in a different name, the taxpayer identification or social
security number of the person named must also be indicated.

8.  U.S. BACKUP TAX WITHHOLDING AND INTERNAL REVENUE SERVICE FORM W-9

     Under the federal income tax laws, payments that may be made by the Company
on account of new Notes issued pursuant to the Exchange Offer may be subject to
backup withholding at the rate of 30.5% (to be reduced to 28% by 2006). Backup
withholding will not apply to each tendering Holder who completes and signs the
Substitute Form W-9 included in this Letter of Transmittal and either (a)
provides the correct taxpayer identification number ("TIN") and certifies, under
penalties of perjury, that the TIN provided is correct and that (1) the Holder
has not been notified by the Internal Revenue Service (the "IRS") that the
Holder is subject to backup withholding as a result of failure to report all
interest or dividends or (2) the IRS has notified the Holder that the Holder is
no longer subject to backup withholding; or (b) provides an adequate basis for
exemption. If the tendering Holder has not been issued a TIN and has applied for
one, or intends to apply for one in the near future, such Holder should write
"Applied For" in the space provided for the TIN in Part I of the Substitute Form
W-9, sign and date the Substitute Form W-9 and sign the Certificate of Payee
Awaiting Taxpayer Identification Number. If "Applied For" is written in Part I,
the Company (or the Exchange Agent under the Indenture governing the new Notes)
will retain 30.5% (or the applicable reduced percentage) of payments made to the
tendering Holder during the 60-day period following the date of the Substitute
Form W-9. If the Holder furnishes the Exchange Agent or the Company with its TIN
within 60 days after the date of the Substitute Form W-9, the Company or the
Exchange Agent, as the case may be, will remit such amounts retained during the
60-day period to the Holder and no further amounts will be retained or withheld
from payments made to the Holder thereafter. If, however, the Holder has not
provided the Exchange Agent or the Company with its TIN within such 60-day
period, the Company or the Exchange Agent, as the case may be, will remit such
previously retained amounts to the IRS as backup withholding. In general, if a
Holder is an individual, the TIN is the social security number of such
individual. If the Exchange Agent or the Company are not provided with the
correct TIN, the Holder may be subject to a $50 penalty imposed by the IRS.
Certain Holders (including, among others, all corporations and certain foreign
individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, such Holder must submit a statement (generally, IRS Form W-8BEN),
signed under penalties of perjury, attesting to that individual's exempt status.
For further information concerning backup withholding and instructions for
completing the Substitute Form W-9 (including how to obtain a taxpayer
identification number if you do not have one and how to complete the Substitute
Form W-9 if old Notes are registered in more than one name), consult the
enclosed Guidelines for

                                        13
<PAGE>

Certification of Taxpayer Identification Number on Substitute Form W-9. Failure
to complete the Substitute Form W-9 will not, by itself, cause old Notes to be
deemed invalidly tendered, but may require the Company or the Exchange Agent, as
the case may be, to withhold 30.5% (or the applicable reduced percentage) of the
amount of any payments made on account of new Notes. Backup withholding is not
an additional federal income tax. Rather, the federal income tax liability of a
person subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained from the IRS.

9.  TRANSFER TAXES

     Holders who tender their old Notes for exchange will not be obligated to
pay any transfer taxes in connection therewith. If, however, certificates
representing new Notes or old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered in the
name of, any person other than the registered Holder of the old Notes tendered
hereby, or if tendered old Notes are registered in the name of a person other
than the person signing this Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of old Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered Holder or on any other persons) will be payable by the tendering
Holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with this Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering Holder. See the Prospectus under
"The Exchange Offer -- Transfer Taxes."

     Except as provided in this Instruction 9, it will not be necessary for
transfer tax stamps to be affixed to the old Notes listed in this Letter of
Transmittal.

10.  WAIVER OF CONDITIONS

     The Company reserves the right, in its sole discretion, to amend, waive or
modify specified conditions in the Exchange Offer in the case of any old Notes
tendered.

11.  MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES

     Any tendering Holder whose old Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated herein for
further instructions.

12.  REQUESTS FOR ASSISTANCE, COPIES

     Requests for assistance and requests for additional copies of the
Prospectus or this Letter of Transmittal may be directed to the Exchange Agent
at the address specified in the Prospectus. Holders may also contact their
broker, dealer, commercial bank, trust company or other nominee for assistance
concerning the Exchange Offer.

number, obtain Form SS-5, Application for a Social Security Number Card (for
individuals), or Form SS-4, Application for Employer Identification Number (for
businesses and all other entities), at the local office of the Social Security
Administration or the Internal Revenue Service and apply for a number.

PAYEES EXEMPT FROM BACKUP WITHHOLDING
Payees specifically exempted from backup withholding on ALL payments include the
following (Section references are to the Internal Revenue Code):
  - An organization exempt from tax under section 501(a), or an individual

    account satisfies the requirements of Section 401(f)(2).
  - The United States or any agency or instrumentality thereof.
  - A State, the District of Columbia, a possession of the United States, or any
    subdivision or instrumentality thereof.
  - A foreign government, a political subdivision of a foreign government, or
    any agency or instrumentality thereof.
  - An international organization, or any agency or instrumentality thereof.
Other payees that may be exempt from backup withholding include:

  - A registered dealer in securities or commodities registered in the U.S. or a
    possession of the U.S.
  - A real estate investment trust.

  - Payments to partnerships not engaged in a trade or business in the U.S. and
    which have at least one nonresident partner.
  - Payments of patronage dividends where the amount received is not paid in
    money.
  - Payments made by certain foreign organizations.
  - Section 404(k) distributions made by an ESOP.
Payments of interest not generally subject to backup withholding include the
following:
  - Payments of interest on obligations issued by individuals.

    NOTE: You may be subject to backup withholding if this interest is $600 or
    more and is paid in the course of the payer's trade or business and you have
    not provided your correct taxpayer identification number to the payer.
  - Payments of tax-exempt interest (including exempt-interest dividends under
    section 852).

  - Payments on tax-free government bonds under section 1451.
  - Payments made by certain foreign organizations.
  - Payments made to a nominee.

Exempt payees described above should file a Substitute Form W-9 to avoid
possible erroneous backup withholding.

FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER,
WRITE "EXEMPT" ON THE FACE OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO
THE PAYER.

Certain payments other than interest, dividends, and patronage dividends, that
are not subject to information reporting are also not subject to backup
withholding. For details, see sections 6041, 6041A(a), 6042, 6044, 6045, 6049,
6050A, and 6050N, and the regulations under those sections.

PRIVACY ACT NOTICE.  Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. The IRS uses the numbers for identification
purposes and to help verify the accuracy of tax returns. Payers must be given
the numbers whether or not recipients are required to file a tax return. Payers
must generally withhold 30.5% of taxable interest, dividend, and certain other
payments to a payee who does not furnish a taxpayer identification number to a
payer. Certain penalties may also apply.

PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.
(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends or
patronage dividends in gross income, such failure is strong evidence of
negligence. If negligence is shown, you will be subject to a penalty of 20% on
any portion of an underpayment attributable to that failure.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

         This Note is one of the duly authorized series of Securities of the

(the "Notes"), initially limited to the aggregate principal amount of
$[__________], all issued or to be issued under and pursuant to an Indenture
dated as of June 29, 1998, as amended, modified or supplemented from time to
time (as so amended, modified or supplemented, the "Indenture"), duly executed
and delivered by the Company and Qwest Communications International Inc., as
successor to U S WEST, Inc. (the "Guarantor"), to Bank One Trust Company,
National Association, as trustee (hereinafter referred to as the "Trustee"), to
which the Indenture and all indentures supplemental thereto reference is hereby
made for a description of the rights, limitation of rights, obligations, duties
and immunities thereunder of the Trustee, the Company, the Guarantor and the
Holders (the words "Holders" or "Holder" meaning the registered holders or
registered holder of the Notes). Exchange Notes (as such term is defined in the
Registration Rights Agreement referred to below) shall be deemed to be of the
same series as the Notes for purposes of the Indenture.

         The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated as of July 30, 2001, among the Company, the Guarantor
and the Initial Purchasers named therein (as the same may be amended from time
to time, the "Registration Rights Agreement"). In the event that (i) the
Exchange Offer Registration Statement (as such term is defined in the
Registration Rights Agreement) is not filed with the Securities and Exchange
Commission (the "Commission") on or prior to the 150th calendar day following
July 30, 2001, (the "Closing Date"), (ii) the Exchange Offer Registration
Statement has not been declared effective by the Commission on or prior to the
210th calendar day following the Closing Date, (iii) the Exchange Offer (as such
term is defined in the Registration Rights Agreement) is not consummated or a
Shelf Registration Statement (as such term is defined in the Registration Rights
Agreement) is not declared effective by the Commission on or prior to the 240th
calendar day following the Closing Date or (iv) the Shelf Registration Statement
has been declared effective but such Shelf Registration Statement ceases to be
effective or the Prospectus (as such term is defined in the Registration Rights
Agreement) ceases to be usable for resales (A) at any time prior to the
expiration of the Effectiveness Period (as such term is defined in the
Registration Rights Agreement) or (B) if related to corporate developments,
public filings or similar events or to correct a material misstatement or
omission in the Prospectus, for more than 60 days (whether or not consecutive)
in any twelve-month period, then in each such case the Special Interest Premium
(as such term is defined in the Registration Rights Agreement) shall accrue in
respect of this Note

                                       3
<PAGE>

from and including the next calendar day following each of (a) such 150-day
period in the case of clause (i) above, (b) such 210-day period in the case of
clause (ii) above, (c) such 240-day period in the case of clause (iii) above,
and from and including such day (in the case of clause (iv)(A) above), or the
61st day after (in the case of clause (iv)(B) above), such Shelf Registration
Statement ceases to be effective or the Prospectus ceases to be usable for
resales, in each case at a rate equal to 0.25% per annum. Any Special Interest
Premium due will be payable in cash on the next succeeding February 3 or August
3, as the case may be, to Holders on the relevant Regular Record Dates for the
payment of interest. The aggregate amount of the Special Interest Premium in
respect of this Note payable pursuant to the above provisions shall in no event
exceed 0.25% per annum; provided, however, that if the Exchange Offer
Registration Statement is not declared effective on or prior to the 240th
calendar day following the Closing Date, and the Company and the Guarantor shall
request the Holder of this Note to provide the information called for by the
Registration Rights Agreement for inclusion in the Shelf Registration Statement,
this Note, if owned by a Holder who does not deliver such information to the
Company and the Guarantor when required pursuant to the Registration Rights
Agreement, will not be entitled to any such Special Interest Premium for any day
after the 240th day following the Closing Date. Upon (1) the filing of the
Exchange Offer Registration Statement after the 150-day period described in
clause (i) above, (2) the effectiveness of the Exchange Offer Registration
Statement after the 210-day period described in clause (ii) above, (3) the
consummation of the Exchange Offer or the effectiveness of a Shelf Registration
Statement, as the case may be, after the 240-day period described in clause
(iii) above or (4) the earlier of (x) the return to effectiveness of the Shelf
Registration Statement or (y) the usability of the Prospectus for resales or (z)
the expiration of the Effectiveness Period (as such term is defined in the
Registration Rights Agreement) (in the case of clause (iv) above), the interest
rate on this Note from the date of such filing, effectiveness, consummation or
expiration of the applicable time period, as the case may be, will be reduced to
the original interest rate of [____]% per annum. The Company shall promptly
provide the Trustee with notice of any change in the interest rate borne by this
Note.

         The Notes shall be redeemable at the option of the Company in whole at
any time or in part from time to time, at a redemption price equal to the
greater of (i) 100% of the principal amount of this Note to be redeemed and (ii)
the sum, as determined by the Quotation Agent (as defined below), of the present
values of the principal amount of this Note to be redeemed and the remaining
scheduled payments of interest on the principal amount of this Note to be
redeemed from the redemption date to [__________, 20__] (the "Remaining Life"),
discounted from their respective scheduled payment dates to the redemption date
on a semiannual basis (assuming a 360-day year consisting of 30-day months) at
the Treasury Rate (as defined below) plus __ basis points, plus, in either case,
accrued interest thereon to the date of redemption.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the Remaining
Life that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity with the Remaining Life.

         "Comparable Treasury Price" means, with respect to any redemption date,
the average of two Reference Treasury Dealer Quotations for such redemption
date.

         "Quotation Agent" means the Reference Treasury Dealer appointed by the
Company.

                                       4
<PAGE>

         "Reference Treasury Dealer" means each of Merrill Lynch Government
Securities Inc. and Lehman Brothers Inc., and their successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), the
Company shall substitute therefor another Primary Treasury Dealer.

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

         "Treasury Rate" means, with respect to any redemption date, the rate
per annum equal to the semiannual yield to maturity of the Comparable Treasury
Issue, calculated on the third Business Day preceding such redemption date using
a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such redemption
date.

         Notice of any redemption will be mailed not less than 15 nor more than
60 calendar days before the redemption date to the Holder hereof at its
registered address. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest will cease to accrue on the
principal amount of this Note.

         If money sufficient to pay the redemption price with respect to and
accrued interest on the principal amount of this Note to be redeemed on the
redemption date is deposited with the Trustee on or before the redemption date
and certain other conditions are satisfied, then on and after such date,
interest will cease to accrue on the principal amount of this Note.

         Except as provided above, this Note is not redeemable by the Company
prior to maturity and is not subject to any sinking fund.

         In case an Event of Default shall occur and be continuing, the
principal hereof may be declared, and upon such declaration shall become, due
and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The Indenture contains provisions permitting the Company, the Guarantor
and the Trustee, with the written consent of the Holders of a majority in
principal amount of the outstanding Securities of each series affected by a
supplemental indenture (with each series voting as a class), to enter into a
supplemental indenture to add any provisions to or to change or eliminate any
provisions of the Indenture or of any supplemental indenture or to modify, in
each case in any manner not covered by provisions in the Indenture relating to
amendments and waivers without the consent of Holders, the rights of the Holders
of each such series. The Holders of a majority in principal amount of the
outstanding Securities of each series affected by such waiver (with each series
voting as a class), by notice to the Trustee, may waive compliance by the
Company or the Guarantor with any provision of the Indenture, any supplemental
indenture or the Securities of any such series, except a Default in payment of
the principal of, premium on or interest on any Security. However, without the
consent of each Holder affected, an amendment or waiver may not: (1) reduce the
amount of Securities whose Holders must consent to an amendment or waiver;

                                       5

(2) change the rate of or change the time for payment of interest on any
Security; (3) change the principal of or change the fixed maturity of any
Security; (4) waive a Default in the payment of the principal of, premium on or

Indenture: (i) with respect to the right of the Holders of a majority in
principal amount of any series of Securities, by notice to the Trustee, to waive
an existing Default with respect to that series and its consequences; (ii) with
respect to the right of any Holder of a Security to receive payment of principal
of, premium on and interest on the Security, on or after the respective due
dates expressed in the Security, the right of any Holder of a coupon to receive
payment of interest due as provided in such coupon, or the right to bring suit
for enforcement of any such payments on or after their respective dates; and
(iii) described in this sentence.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Note at the place, at the respective times, at the rate, and in
the coin or currency herein prescribed.

         No director, officer, employee or stockholder, as such, of the Company
or the Guarantor shall have any liability for any obligations of the Company
under this Note or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder, by accepting this
Note, waives and releases all such liability. The waiver and release are part of
the consideration for the issue of this Note and the Guarantee endorsed hereon.

         The laws of the State of New York shall govern the Indenture and this
Note.

         Ownership of this Note shall be proved by the register for the Notes
kept by the Registrar. The Company, the Guarantor, the Trustee and any agent of
the Company may treat the person in whose name a Note is registered as the
absolute owner thereof for all purposes.

         Terms used herein without definition that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

Note, when and as the same shall become due and payable, whether at maturity or
otherwise, according to the terms thereof and of the Indenture referred to
therein.

         The Guarantor agrees to determine, at least one business day prior to
the date upon which a payment of principal, premium, if any, or interest on said
Note is due and payable, whether Qwest Capital Funding, Inc. (the "Company") has

payable. In case of the failure of the Company punctually to pay any such
principal, premium, if any, or interest, the Guarantor hereby agrees to cause
any such payment to be made punctually when and as the same shall become due and
payable, whether at maturity or otherwise, and as if such payment were made by
the Company.

         The Guarantor hereby agrees that its obligations hereunder shall be
unconditional, irrevocable and absolute, irrespective of the validity,
regularity, or enforceability of said Note or the Indenture, dated as of June

claims with a court in the event of merger or bankruptcy of the Company, any
right to require a proceeding first against the Company, protest or notice with

interest on all Notes of the Company known as "[____]% Notes due [__________,
20__]" shall have been paid in full or payment thereof shall have been provided
for in accordance with said Indenture.

         Notwithstanding anything to the contrary contained herein, if following
any payment of principal, premium, if any, or interest by the Company on the

court of competent jurisdiction that such payment shall be avoided by a trustee
in bankruptcy (including any debtor-in-possession) as a preference under 11
U.S.C. Section 547 and such payment is paid by such holder to such trustee in
bankruptcy, then and to the extent of such repayment the obligations of the
Guarantor hereunder shall remain in full force and effect.

         QWEST CAPITAL FUNDING, INC. (formerly known as U S WEST Capital

State of Colorado (such corporation, and its successors and assigns under the
Indenture hereinafter referred to, being herein called the "Company"), for value

         This Note is one of the duly authorized series of Securities of the
Company, designated as the Company's "[____]% Notes due [___________, 20__]"
(the "Notes"), initially limited to the aggregate principal amount of
$[__________], all issued or to be issued under and pursuant to an Indenture
dated as of June 29, 1998, as amended, modified or supplemented from time to
time (as so amended, modified or supplemented, the "Indenture"), duly executed
and delivered by the Company and Qwest Communications International Inc. (as
successor to U S WEST, Inc.), (the "Guarantor"), to Bank One Trust Company,
National Association, as trustee (hereinafter referred to as the "Trustee"), to
which Indenture and all Indentures supplemental thereto reference is hereby made
for a description of the rights, limitation of rights, obligations, duties and
immunities thereunder of the Trustee, the Company, the Guarantor and the Holders
(the words "Holders" or "Holder" meaning the registered holders or registered
holder of the Notes). Exchange Notes (as such term is defined in the
Registration Rights Agreement referred to below) shall be deemed to be of the
same series as the Notes for purposes of the Indenture.

         The Holder of this Note is entitled to the benefits of the Registration
Rights Agreement, dated as of July 30, 2001, among the Company, the Guarantor
and the Initial Purchasers named therein (as the same may be amended from time
to time, the "Registration Rights Agreement"). In the event that (i) the
Exchange Offer Registration Statement (as such term is defined in the
Registration Rights Agreement) is not filed with the Securities and Exchange
Commission (the "Commission") on or prior to the 150th calendar day following
July 30, 2001, (the "Closing Date"), (ii) the Exchange Offer Registration
Statement has not been declared effective by the Commission on or prior to the
210th calendar day following the Closing Date, (iii) the Exchange Offer (as such
term is defined in the Registration Rights Agreement) is not consummated or a
Shelf Registration Statement (as such term is defined in the Registration Rights
Agreement) is not declared effective by the Commission on or prior to the 240th
calendar day following the Closing Date or (iv) the Shelf Registration Statement
has been declared effective but such Shelf Registration Statement ceases to be
effective or the Prospectus (as such term is defined in the Registration Rights
Agreement) ceases to be usable for resales (A) at any time prior to the
expiration of the Effectiveness Period (as such term is defined in the
Registration Rights Agreement) or (B) if related to corporate developments,
public filings or similar events or to correct a material misstatement or
omission in the Prospectus, for more than 60 days (whether or not consecutive)
in any twelve-month period, then in each such case the Special Interest Premium
(as such term is defined in the Registration Rights Agreement) shall accrue in
respect of this Note from and including the next calendar day following each of
(a) such 150-day period in the case of clause (i) above, (b) such 210-day period
in the case of clause (ii) above, (c) such 240-day period in the case of clause
(iii) above, and from and including such day (in the case of clause (iv)(A)
above), or the 61st day after (in the case of clause (iv)(B) above), such Shelf
Registration Statement ceases to be effective or the Prospectus ceases to be
usable for resales, in each case at a rate equal to 0.25% per annum. Any Special
Interest Premium due will be payable in cash on the

                                       3
<PAGE>

next succeeding February 3 or August 3, as the case may be, to Holders on the
relevant Regular Record Dates for the payment of interest. The aggregate amount
of the Special Interest Premium in respect of this Note payable pursuant to the
above provisions shall in no event exceed 0.25% per annum; provided, however,
that if the Exchange Offer Registration Statement is not declared effective on
or prior to the 240th calendar day following the Closing Date, and the Company
and the Guarantor shall request the Holder of this Note to provide the
information called for by the Registration Rights Agreement for inclusion in the
Shelf Registration Statement, this Note, if owned by a Holder who does not
deliver such information to the Company and the Guarantor when required pursuant
to the Registration Rights Agreement, will not be entitled to any such Special
Interest Premium for any day after the 240th day following the Closing Date.
Upon (1) the filing of the Exchange Offer Registration Statement after the
150-day period described in clause (i) above, (2) the effectiveness of the
Exchange Offer Registration Statement after the 210-day period described in
clause (ii) above, (3) the consummation of the Exchange Offer or the
effectiveness of a Shelf Registration Statement, as the case may be, after the
240-day period described in clause (iii) above or (4) the earlier of (x) the
return to effectiveness of the Shelf Registration Statement or (y) the usability
of the Prospectus for resales or (z) the expiration of the Effectiveness Period
(as such term is defined in the Registration Rights Agreement) (in the case of
clause (iv) above), the interest rate on this Note from the date of such filing,
effectiveness, consummation or expiration of the applicable time period, as the
case may be, will be reduced to the original interest rate of [___]% per annum.
The Company shall promptly provide the Trustee with notice of any change in the
interest rate borne by this Note.

         The Notes shall be redeemable at the option of the Company in whole at
any time or in part from time to time, at a redemption price equal to the
greater of (i) 100% of the principal amount of this Note to be redeemed and (ii)
the sum, as determined by the Quotation Agent (as defined below), of the present
values of the principal amount of this Note to be redeemed and the remaining
scheduled payments of interest on the principal amount of this Note to be
redeemed from the redemption date to [__________, 20__] (the "Remaining Life"),
discounted from their respective scheduled payment dates to the redemption date
on a semiannual basis (assuming a 360-day year consisting of 30-day months) at
the Treasury Rate (as defined below) plus __ basis points, plus, in either case,
accrued interest thereon to the date of redemption.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the Remaining
Life that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity with the Remaining Life.

         "Comparable Treasury Price" means, with respect to any redemption date,
the average of two Reference Treasury Dealer Quotations for such redemption
date.

         "Quotation Agent" means the Reference Treasury Dealer appointed by the
Company.

         "Reference Treasury Dealer" means each of Merrill Lynch Government
Securities Inc. and Lehman Brothers Inc., and their successors; provided,
however, that if any of the foregoing shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), the
Company shall substitute therefor another Primary Treasury Dealer.

                                       4
<PAGE>

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

         "Treasury Rate" means, with respect to any redemption date, the rate
per annum equal to the semiannual yield to maturity of the Comparable Treasury
Issue, calculated on the third Business Day preceding such redemption date using
a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such redemption
date.

         Notice of any redemption will be mailed not less than 15 nor more than
60 calendar days before the redemption date to the Holder hereof at its
registered address. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest will cease to accrue on the
principal amount of this Note.

         If money sufficient to pay the redemption price with respect to and
accrued interest on the principal amount of this Note to be redeemed on the
redemption date is deposited with the Trustee on or before the redemption date
and certain other conditions are satisfied, then on and after such date,
interest will cease to accrue on the principal amount of this Note.

         Except as provided above, this Note is not redeemable by the Company
prior to maturity and is not subject to any sinking fund.

         In case an Event of Default shall occur and be continuing, the
principal hereof may be declared, and upon such declaration shall become, due
and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The Indenture contains provisions permitting the Company, the Guarantor
and the Trustee, with the written consent of the Holders of a majority in
principal amount of the outstanding Securities of each series affected by a
supplemental indenture (with each series voting as a class), to enter into a
supplemental indenture to add any provisions to or to change or eliminate any
provisions of the Indenture or of any supplemental indenture or to modify, in
each case in any manner not covered by provisions in the Indenture relating to
amendments and waivers without the consent of Holders, the rights of the Holders
of each such series. The Holders of a majority in principal amount of the
outstanding Securities of each series affected by such waiver (with each series
voting as a class), by notice to the Trustee, may waive compliance by the
Company or the Guarantor with any provision of the Indenture, any supplemental
indenture or the Securities of any such series, except a Default in payment of
the principal of, premium on or interest on any Security. However, without the
consent of each Holder affected, an amendment or waiver may not: (1) reduce the
amount of Securities whose Holders must consent to an amendment or waiver; (2)
change the rate of or change the time for payment of interest on any Security;
(3) change the principal of or change the fixed maturity of any Security; (4)
waive a Default in the payment of the principal of, premium on or interest on
any Security; (5) make any Security payable in money other than that stated in

any series of

                                       5

Securities, by notice to the Trustee, to waive an existing Default with respect
to that series and its consequences; (ii) with respect to the right of any
Holder of a Security to receive payment of principal of, premium on and interest
on the Security, on or after the respective due dates expressed in the Security,
the right of any Holder of a coupon to receive payment of interest due as
provided in such coupon, or the right to bring suit for enforcement of any such
payments on or after their respective dates; and (iii) described in this
sentence.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Note at the place, at the respective times, at the rate, and in
the coin or currency herein prescribed.

         No director, officer, employee or stockholder, as such, of the Company
or the Guarantor shall have any liability for any obligations of the Company
under this Note or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder, by accepting this
Note, waives and releases all such liability. The waiver and release are part of
the consideration for the issue of this Note and the Guarantee endorsed hereon.

         The laws of the State of New York shall govern the Indenture and this
Note.

         Ownership of this Note shall be proved by the register for the Notes
kept by the Registrar. The Company, the Guarantor, the Trustee and any agent of

absolute owner thereof for all purposes.

              GUARANTEE OF QWEST COMMUNICATIONS INTERNATIONAL INC.

         FOR VALUE RECEIVED, Qwest Communications International Inc., a
corporation duly organized and existing under the laws of the State of Delaware
(the "Guarantor"), hereby unconditionally guarantees to the holder of the Note
upon which this Guarantee is endorsed the due and punctual payment of the
principal, premium, if any, and interest on said Note, when and as the same
shall become due and payable, whether at maturity or otherwise, according to the
terms thereof and of the Indenture referred to therein.

         The Guarantor agrees to determine, at least one business day prior to
the date upon which a payment of principal, premium, if any, or interest on said
Note is due and payable, whether Qwest Capital Funding, Inc. (the "Company") has
available the funds to make such payment as the same shall become due and
payable. In case of the failure of the Company punctually to pay any such
principal, premium, if any, or interest, the Guarantor hereby agrees to cause
any such payment to be made punctually when and as the same shall become due and
payable, whether at maturity or otherwise, and as if such payment were made by
the Company.

         The Guarantor hereby agrees that its obligations hereunder shall be
unconditional, irrevocable and absolute, irrespective of the validity,
regularity, or enforceability of said Note or the Indenture, dated as of June
29, 1998, as amended, modified or supplemented from time to time (as so amended,
modified or supplemented, the "Indenture"), by and among the Company, the
Guarantor (as successor to U S WEST, Inc.) and Bank One Trust Company, National
Association, as trustee (hereinafter referred to as the "Trustee"), the absence
of any action to enforce the same, any waiver or consent by the holder of said
Note with respect to any provisions thereof, the recovery of any judgment
against the Company or any action to enforce the same, or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. The Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of merger or bankruptcy of
the Company, any right to require a proceeding first against the Company,
protest or notice with respect to said Note or indebtedness evidenced thereby
and all demands whatsoever and covenants that this Guarantee will not be
discharged except by complete performance of the obligations contained in said
Note and in this Guarantee.

         The Guarantor shall be subrogated to all rights of the holder of said
Note against the Company in respect to any amounts paid by the Guarantor
pursuant to the provisions of this Guarantee; provided, however, that the
Guarantor shall not, without the consent of the holders of all of the Notes then
outstanding, be entitled to enforce or to receive any payments arising out of or
based upon such right of subrogation until the principal, premium, if any, and
interest on all Notes of the Company known as "[____]% Notes due [__________,
20__]" shall have been paid in full or payment thereof shall have been provided
for in accordance with said Indenture.

         Notwithstanding anything to the contrary contained herein, if following
any payment of principal, premium, if any, or interest by the Company on the
Notes to the holders of the Notes it is determined by a final decision of a
court of competent jurisdiction that such payment shall be avoided by a trustee
in bankruptcy (including any debtor-in-possession) as a preference under 11
U.S.C. Section 547 and such payment is paid by such holder to such trustee in
bankruptcy, then and to

                                       8

the extent of such repayment the obligations of the Guarantor hereunder shall

with respect to a Note until the certificate of authentication of such Note
shall have been signed by the Trustee or on its behalf by the Trustee's
authenticating agent.

         This Guarantee shall be governed by the laws of the State of New York.

         Definitive Notes of other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if
its reasonable requirements for such transaction are met; provided, however,
that the Definitive Notes surrendered for transfer or exchange:

         (i) shall be duly endorsed or accompanied by a written instrument of
transfer in form reasonably satisfactory to the Corporation and the Registrar,
duly executed by the Holder thereof or his attorney duly authorized in writing;
and

         (ii) are accompanied by the following additional information and
documents, as applicable:

                  (A) if such Definitive Notes are being delivered to the
         Registrar by a Holder for registration in the name of such Holder,
         without transfer, a certification from such Holder to that effect (in
         the form set forth on the reverse side of the Note);

                  (B) if such Definitive Notes are being transferred to the
         Corporation, a certification to that effect (in the form set forth on
         the reverse side of the Note); or

                  (C) if such Definitive Notes are being transferred pursuant to
         an exemption from registration in accordance with Rule 144 under the
         Securities Act or in reliance upon another exemption from the
         registration requirements of the Securities Act, (i) a certification to
         that effect (in the form set forth on the reverse side of the Note) and

         evidence reasonably satisfactory to it as to the compliance with the
         restrictions set forth in the legend set forth in Section 2.2(e)(i).

         (b) Restrictions on Transfer of a Definitive Note for a Beneficial
Interest in a Global Note. A Definitive Note may not be exchanged for a
beneficial interest in a Global Note except upon satisfaction of the
requirements set forth below. Upon receipt by the Trustee of a Definitive Note,
duly endorsed or accompanied by a written instrument of transfer in form
reasonably satisfactory to the Corporation and the Registrar, together with:

         (i) certification (in the form set forth on the reverse side of the
Initial Note) that such Definitive Note is being transferred (A) to a QIB in
accordance with Rule 144A or (B) outside the United States in an offshore
transaction within the meaning of Regulation S and in compliance with Rule 904
under the Securities Act; and

         (ii) written instructions directing the Trustee to make, or to direct
the Securities Custodian to make, an adjustment on its books and records with
respect to such Global Note to reflect an increase in the aggregate principal
amount of the Notes represented by the Global Note, such instructions to contain
information regarding the Depositary account to be credited with such increase,

then the Trustee shall cancel such Definitive Note and cause, or direct the
Securities Custodian to cause, in accordance with the standing instructions and
procedures existing between the

<PAGE>

Depositary and the Securities Custodian, the aggregate principal amount of Notes
represented by the Global Note to be increased by the aggregate principal amount
of the Definitive Note to be exchanged and shall credit or cause to be credited
to the account of the Person specified in such instructions a beneficial
interest in the Global Note equal to the principal amount of the Definitive Note
so canceled. If no Global Notes are then outstanding and the Global Note has not
been previously exchanged for certificated Notes pursuant to Section 2.3, the
Corporation shall issue and the Trustee shall authenticate, upon written order
of the Corporation in the form of an Officers' Certificate, a new Global Note in
the appropriate principal amount.

         (c) Transfer and Exchange of Global Notes. (i) The transfer and
exchange of Global Notes or beneficial interests therein shall be effected
through the Depositary, in accordance with the Indenture and this Appendix A
(including applicable restrictions on transfer set forth herein, if any) and the
procedures of the Depositary therefor. A transferor of a beneficial interest in
a Global Note shall deliver a written order given in accordance with the
Depositary's procedures containing information regarding the participant account
of the Depositary to be credited with a beneficial interest in such Global Note
or another Global Note and such account shall be credited in accordance with
such order with a beneficial interest in the applicable Global Note and the
account of the Person making the transfer shall be debited by an amount equal to
the beneficial interest in the Global Note being transferred. Transfers by an
owner of a beneficial interest in the Rule 144A Global Note to a transferee who
takes delivery of such interest through the Regulation S Global Note, whether
before or after the expiration of the Restricted Period, shall be made only upon
receipt by the Trustee of a certification from the transferor to the effect that
such transfer is being made in accordance with Regulation S or (if available)
Rule 144 under the Securities Act and that, if such transfer is being made prior
to the expiration of the Restricted Period, the interest transferred shall be
held immediately thereafter through Euroclear or Clearstream.

         (ii) If the proposed transfer is a transfer of a beneficial interest in
one Global Note to a beneficial interest in another Global Note, the Registrar
shall reflect on its books and records the date and an increase in the principal
amount of the Global Note to which such interest is being transferred in an
amount equal to the principal amount of the interest to be so transferred, and
the Registrar shall reflect on its books and records the date and a
corresponding decrease in the principal amount of Global Note from which such
interest is being transferred.

         (iii) Notwithstanding any other provisions of this Appendix A (other
than the provisions set forth in Section 2.3), a Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

         (d) Restrictions on Transfer of Regulation S Global Note. (i) Prior to
the expiration of the Restricted Period, interests in the Regulation S Global
Note may only be held through Euroclear or Clearstream. During the Restricted
Period, beneficial ownership interests in the Regulation S Global Note may only
be sold, pledged or transferred through Euroclear or Clearstream in accordance
with the Applicable Procedures and only (A) to the Corporation, (B) so long as
such security is eligible for resale pursuant to Rule 144A, to a person whom the
selling holder reasonably believes is a QIB that purchases for its own account
or for the account

<PAGE>

of a QIB to whom notice is given that the resale, pledge or transfer is being
made in reliance on Rule 144A, (C) in an offshore transaction in accordance with
Regulation S, (D) pursuant to an exemption from registration under the
Securities Act provided by Rule 144 (if applicable) under the Securities Act or
(E) pursuant to an effective registration statement under the Securities Act, in
each case in accordance with any applicable securities laws of any state of the
United States. Prior to the expiration of the Restricted Period, transfers by an
owner of a beneficial interest in the Regulation S Global Note to a transferee
who takes delivery of such interest through the Rule 144A Global Note shall be
made only in accordance with Applicable Procedures and upon receipt by the
Trustee of a written certification from the transferor of the beneficial
interest in the form provided on the reverse of the Initial Note to the effect

         "THE HOLDER OF THIS NOTE BY ITS ACCEPTANCE HEREOF IS DEEMED TO HAVE
         AGREED TO BE BOUND BY THE PROVISIONS OF A REGISTRATION RIGHTS AGREEMENT
         AMONG THE COMPANY, QWEST COMMUNICATIONS INTERNATIONAL INC., AND THE

         ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT
         ("RULE 144A") TO A PERSON IT REASONABLY BELIEVES IS A "QUALIFIED
         INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A) THAT PURCHASES FOR ITS
         OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO
         WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON
         RULE 144A, (D) IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904
         OF REGULATION S UNDER THE SECURITIES ACT OR (E) PURSUANT TO ANY OTHER
         AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT, SUBJECT TO THE COMPANY'S AND THE TRUSTEE'S (AS DEFINED
         BELOW) RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO
         CLAUSE (D) OR (E) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL,
         CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM.
         THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE
         RESALE RESTRICTION TERMINATION DATE.

Each Regulation S Note shall bear the following additional legend:

         THE HOLDER OF THIS NOTE BY ACCEPTANCE HEREOF ALSO AGREES, REPRESENTS
         AND WARRANTS THAT IF IT IS A PURCHASER IN A SALE THAT OCCURS OUTSIDE
         THE UNITED STATES WITHIN THE MEANING OF REGULATION S OF THE SECURITIES
         ACT, IT ACKNOWLEDGES THAT, UNTIL EXPIRATION OF THE "40-DAY DISTRIBUTION
         COMPLIANCE PERIOD" WITHIN THE MEANING OF RULE 903 OF REGULATION S, ANY
         OFFER OR SALE OF THIS NOTE SHALL NOT BE MADE BY IT TO A U.S. PERSON TO

         902(o) UNDER THE SECURITIES ACT."

Each Definitive Note shall bear the following additional legend:

         IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE
         REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS
         SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER
         COMPLIES WITH THE FOREGOING RESTRICTIONS."

         (ii) Upon any sale or transfer of a Transfer Restricted Note that is a
Definitive Note, the Registrar shall permit the Holder thereof to exchange such
Transfer Restricted Note for a Definitive Note that does not bear the legends
set forth above and rescind any restriction on the transfer of such Transfer
Restricted Note if the Holder certifies in writing to the Registrar that its
request for such exchange was made in reliance on Rule 144 (such certification
to be in the form set forth on the reverse of the Initial Note).

<PAGE>

         (iii) Upon a sale or transfer after the expiration of the Restricted
Period of any Note acquired pursuant to Regulation S, all requirements that such
Note bear the Restricted Notes Legend shall cease to apply and the requirements
requiring any such Note be issued in global form shall continue to apply.

         (f) Cancellation or Adjustment of Global Note. At such time as all
beneficial interests in a Global Note have either been exchanged for Definitive
Notes, transferred, redeemed, repurchased or cancelled, such Global Note shall
be returned by the Depositary to the Trustee for cancellation or retained and
cancelled by the Trustee. At any time prior to such cancellation, if any
beneficial interest in a Global Note is exchanged for Definitive Notes,
transferred in exchange for an interest in another Global Note, redeemed,
repurchased or cancelled, the principal amount of Notes represented by such
Global Note shall be reduced and an adjustment shall be made on the books and
records of the Trustee (if it is then the Securities Custodian for such Global
Note) with respect to such Global Note, by the Trustee or the Securities
Custodian, to reflect such reduction.

         (g) Obligations with Respect to Transfers and Exchanges of Notes.

         (i) To permit registrations of transfers and exchanges, the Corporation
shall execute and the Trustee shall authenticate, Definitive Notes and Global
Notes at the Registrar's request.

         (ii) No service charge shall be made for any registration of transfer
or exchange, but the Corporation may require payment of a sum sufficient to
cover any transfer tax, assessments, or similar governmental charge payable in
connection therewith.

         (iii) Prior to the due presentation for registration of transfer of any
Note, the Corporation, the Trustee, the Paying Agent or the Registrar may deem
and treat the person in whose name a Note is registered as the absolute owner of
such Note for the purpose of receiving payment of principal of and interest on
such Note and for all other purposes whatsoever, whether or not such Note is
overdue, and none of the Corporation, the Trustee, the Paying Agent or the
Registrar shall be affected by notice to the contrary.

         (iv) All Notes issued upon any transfer or exchange pursuant to the
terms of the Indenture and this Appendix A shall evidence the same debt and
shall be entitled to the same benefits under the Indenture as the Notes
surrendered upon such transfer or exchange.

         (h) No Obligation of the Trustee.

the Depository or its nominee or of any participant or member thereof, with
respect to any ownership interest in the Notes or with respect to the delivery
to any participant, member, beneficial owner or other Person (other than the
Depositary) of any notice (including any notice of redemption or repurchase) or
the payment of any amount, under or with respect to such Notes. All notices and

The rights of beneficial owners in any Global Note shall be exercised only
through the Depositary subject to the applicable rules and procedures of the

relying upon information furnished by the Depositary with respect to its
members, participants and any beneficial owners.

         (ii) The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer imposed under the

required by, the terms of the Indenture and this Appendix A, and to examine the
same to determine substantial compliance as to form with the express
requirements hereof.
