                       QWEST COMMUNICATIONS CORPORATION
                        PRIVATE LINE SERVICES AGREEMENT


     This Private Line Services Agreement, is entered into as of June 1, 1999
     (the "Effective Date"), by and between Qwest Communications Corporation, a
     Delaware corporation ("Qwest"), and Advanced Radio Telecom Corp., a
     Delaware corporation ("Customer").

1.   INCORPORATION OF DOCUMENTS AND CONTROLLING PROVISIONS
     -----------------------------------------------------

1.1  This Service Agreement, together with (a) Service Orders (as defined in
     Section 2.1 of this Service Agreement) accepted by Qwest pursuant to the
     terms hereof, and (b) schedules and exhibits incorporated herein by
     reference ("Exhibits"), shall be referred to collectively herein as this
     "Agreement."  In the event of any conflict between the provisions of this
     Agreement and the terms of any Service Order(s) and/or Exhibit(s), the
     conflict shall be resolved by reference to said documents in the following
     order of priority of interpretation:  (a) this Agreement; (b) any
     Exhibit(s), with reference to the same in order of attachment to this
     Agreement; and (c) any Service Order(s).  Notwithstanding the foregoing, no
     provision or term of any Service Order shall be a part of this Agreement or
     binding on Qwest unless and until such Service Order has been executed by
     an authorized representative of Qwest.

1.2  If any provision of this Agreement and any applicable tariff cannot be
     reasonably construed or interpreted to avoid conflict, the provision
     contained in this Agreement shall prevail. The fact that a condition,
     right, obligation, or other term appears in this Agreement but not in any
     such tariff shall not be interpreted as, or be deemed grounds for finding
     of a conflict for purposes of this Section 1.2.  In addition, if any
     provision of this Agreement conflicts with any statute, rule or order of
     any governmental unit or regulatory body, then, if required by law, this
     Agreement should remain in effect but shall be automatically modified by
     such conflicting law, statute, rule or order, subject to the termination
     rights granted herein under Section 8.

2.   SERVICES TO BE PROVIDED BY QWEST
     --------------------------------

2.1  Telecommunications capacity, and related ancillary services (the "Facility"
     or "Facilities") available from Qwest are identified in the Service and
     Pricing Exhibit attached hereto as "Exhibit A", which is incorporated by
     this reference (the "Service and Pricing Exhibit").  Facilities requested
     by Customer shall be requested on Qwest's service order forms in effect
     from time to time (hereafter, any such order is a "Service Order(s)").
     Each Service Order shall reference this Agreement and shall become a part
     of this Agreement when executed by a duly authorized representative of
     Qwest.  Qwest reserves the right to reject any Service Order in areas where
     facilities or capacity are unavailable or the provision of service would be
     otherwise technically unreasonable.

                                       1
<PAGE>

2.2  Upon acceptance by Qwest of a duly executed Service Order during the Term
     (as defined in Section 4.3 of this Agreement) of this Agreement, Qwest
     shall provide to Customer those Facilities identified in the Service Order.

3.   OBLIGATIONS OF CUSTOMER
     -----------------------

3.1  Customer shall perform those duties outlined in the Service and Pricing
     Exhibit in addition to those described herein and in any Service Order(s).

3.2  Customer shall have sole responsibility for installation, testing and
     operation of the Interconnection Facilities (as defined in Section 1.4 of
     the Service and Pricing Exhibit), and any services and equipment other than
     those Facilities specifically provided by Qwest under this Agreement.

4.   TERM
     ----

4.1  This Agreement shall be effective between the parties as of the Effective
     Date.   The initial term (the "Initial Term") of this Agreement shall
     expire seven (7) years from the Effective Date unless either party earlier
     terminates this Agreement in accordance with Section 8.

4.2  Upon the expiration of the Initial Term, if Customer is not then in default
     hereunder, the term of this Agreement shall be renewed automatically on a
     month-to-month basis (hereafter, the "Renewal Term") unless and until an
     Amendment is executed by both parties extending the Renewal Term, or either
     party terminates this Agreement in accordance with Section 8.

4.3  The Initial Term and Renewal Term are sometimes referred to together herein
     as the "Term."

4.4  Notwithstanding anything to the contrary in this Section 4, if the Facility
     Minimum Service Term (as set forth in Section 4.2 of the Service and
     Pricing Exhibit) for a Facility or Facilities extends beyond the expiration
     of the Term of this Agreement, then this Agreement shall continue in effect
     until the expiration or termination of the applicable Facility Minimum
     Service Term, but only as to the Facility or Facilities so affected, and
     subject to the termination rights of Qwest and Customer under Section 8 of
     this Agreement.

5.   CHARGES AND PAYMENT
     -------------------

5.1  Charges for the Facilities shall be determined according to the Service and
     Pricing Exhibit except as otherwise specifically provided in this
     Agreement.

5.2  Recurring charges shall be invoiced by Qwest on a monthly basis in advance
     and non-recurring charges shall be invoiced in arrears.  If the Start of
     Service Date (as defined in Section 2.1 of the Service and Pricing Exhibit)
     for any Facility falls on other than the first

                                       2
<PAGE>

     day of any month, the first invoice to Customer shall consist of: (1) the
     pro-rata portion of the applicable monthly charge covering the period from
     the Start of Service Date to the first day of the subsequent month, and (2)
     the monthly charge for the following month. Qwest may, in its sole
     discretion, prior to delivering the first invoice to Customer, elect to
     require that Customer make a security deposit amount equal to one (1)
     month's recurring charges for the Facility or Facilities. If a deposit is
     made, it shall be held by Qwest until termination of this Agreement, at
     which time Qwest may apply the deposit, at its option, either against the
     last month of charges due hereunder prior to termination of this Agreement,
     or against any other amounts owing to Qwest under this Agreement.

5.3  Customer shall make all payments due hereunder within  thirty (30) days
     after the date of Qwest's invoice.  If any amount due under this Agreement
     is not received by the due date, in addition to its other remedies
     available hereunder, Qwest may in its sole discretion impose a late payment
     charge of the lower of 1.5% per month or the highest rate legally
     permissable (such late charge shall be payable upon demand by Qwest).
     Notwithstanding anything in this Agreement to the contrary, no payment due
     hereunder is subject to reduction, set-off or adjustment of any nature by
     Customer, except as is specifically provided in Section 5 of the Service
     and Pricing Exhibit regarding Outage Credits. In no event shall the
     malfunction or non-operation of Customer's Interconnection Facilities
     (including local access when Customer is responsible therefor) relieve
     Customer of its obligation to pay for the Facilities.

5.4  All disputes or requests for billing adjustments must be submitted in
     writing and submitted with payment of undisputed amounts due, or
     alternatively, if Customer has paid an invoice amount in full, Customer
     shall have one hundred eighty (180) days from the date of invoice to give
     notice of a dispute regarding amounts invoiced therein.  Any amounts which
     are determined by Qwest to be in error or not in compliance with this
     Agreement shall be adjusted on the next month's invoice.  Any disputed
     amounts which reasonably, in good faith and supported by reasonable
     documentation are deemed by Qwest to be correct as billed and in compliance
     with this Agreement, shall be due and payable by Customer (if not
     previously paid), upon notification and demand by Qwest, along with any
     late payment charges which Qwest may impose pursuant to Section 5.3 above.
     Disputes shall not be cause for Customer to delay payment of the undisputed
     balance to Qwest according to the terms outlined in Section 5.3 above.
     Subject to the payment obligations described in this Section 5, Customer
     may pursue arbitration of any dispute not resolved hereunder pursuant to
     Section 16.

5.5  Invoices submitted to Customer by Qwest shall conform to Qwest's standard
     billing format and content, as modified by Qwest from time to time.

5.6  Any applicable federal, state, or local taxes, and all use, sales,
     commercial, gross receipts, privilege or other similar taxes or license
     fees, whether charged to or against Qwest or Customer, with respect to the
     Facilities provided by Qwest (except taxes on Qwest's income or gains), as
     well as any other imposition by any governmental authority which

                                       3
<PAGE>

     has the effect of increasing Qwest's cost of providing the Facilities,
     shall be payable by Customer in addition to the other charges set forth in
     this Agreement.

6.   EVENTS OF DEFAULT
     -----------------

6.1  A "Default" shall occur if:  (a) Customer fails to make any payment
     required to be made by it under this Agreement and any such failure remains
     uncorrected for five (5) business days after receipt of written notice that
     such payment is past due; (b) either party fails to perform or observe any
     material term or obligation (other than making payment) contained in this
     Agreement, and any such failure remains uncorrected for thirty (30)
     calendar days after written notice from the non-defaulting party informing
     the defaulting party of such failure; or (c) there is an Adverse Material
     Change (as defined in Section 6.2 of this Agreement) in Customer's
     creditworthiness.

6.2  For purposes of Section 6.1 of this Agreement, an Adverse Material Change
     in Customer's creditworthiness shall include, but not be limited to:  (a)
     failure of Customer to make full payment of charges due hereunder on or
     before the date due on three (3) or more occasions during any period of
     twelve (12) months, or Customer's failure to make such payment on or before
     the date due in any two (2) consecutive months; (b) acquisition of Customer
     (whether in whole or by majority or controlling interest) by an entity
     which is insolvent, which is subject to bankruptcy or insolvency
     proceedings, or which presents a materially greater credit risk than
     Customer; or (c) Customer being subject to or having filed for bankruptcy
     or insolvency proceedings, or the legal insolvency of Customer.

6.3  Notwithstanding Section 6.1 of this Agreement, the failure of any
     particular circuit or number of circuits to comply with the Specifications
     (as that term is defined in Section 2.1 of the Service and Pricing Exhibit)
     shall not be deemed a Default by Qwest, but may obligate Qwest to provide
     Customer with Outage Credits, as provided in Section 5 of the Service and
     Pricing Exhibit.

7.   REMEDIES FOLLOWING DEFAULT
     --------------------------

7.1  If Customer is in Default, Qwest may, in addition to any other remedies it
     has under this Agreement or under the law:  (a) suspend its performance
     under this Agreement without the requirement of any further notice to
     Customer, until Customer has remedied all breaches of this Agreement and
     paid in full all charges then due, including any late fees specified herein
     plus; (b) condition provision of Facilities or acceptance of a Service
     Order on Customer's assurance of payment and compliance with this
     Agreement, which may be in the form of a deposit/prepayment or such other
     means as is required by Qwest to establish assurance of payment and
     compliance; or (c) terminate this Agreement by providing written notice to
     Customer in the manner provided in Section 8.2 of this Agreement.

7.2  If Qwest is in Default, Customer may terminate this Agreement pursuant to
     Section 8.1 below, but may not withhold or suspend its own performance.

8.   TERMINATION
     -----------

8.1  Customer may terminate this Agreement without liability (other than charges
     accrued but unpaid as of the termination date):  (a) effective upon written
     notice to Qwest, if Qwest is in Default; (b) effective upon thirty (30)
     calendar days prior written notice, if any material rate or term contained
     herein and relevant to all or substantially all of the Facilities is
     materially changed by order of the highest court of competent jurisdiction
     to which the matter is appealed, the Federal Communications Commission, or
     other local, state or federal government authority; (c) following a Default
     by Qwest  under Section 9.2 of this Agreement affecting all or
     substantially all of the Facilities; (d) if Qwest makes an unauthorized
     transfer under Section 12 of this Agreement; or (e) effective upon thirty
     (30) calendar days prior written notice, with or without cause, following

     prior written notice, with or without cause, following the expiration of
     the Initial Term; or (c) effective immediately and without any advance
     written notice: (i) if Qwest loses any required regulatory or other
     governmental authorizations to provide all or substantially all of the
     Facilities (as described in Section 9.1 of this Agreement); (ii) following
     a default by Customer under Section 9.2 of this Agreement affecting all or
     substantially all of the Facilities; or (iii) if Customer makes an
     unauthorized Transfer under Section 12 of this Agreement.

8.3  In the event of any termination pursuant to Section 8.1 hereof as a result
     of Qwest's breach of its obligations  under this Agreement, Qwest agrees to
     cooperate with Customer, on a commercially reasonable efforts basis, to
     transition existing services and Facilities used by Customer to serve end
     users to another network operator; except, that Qwest shall be obligated to
     assist this transition only if Customer is and remains in compliance with
     its payment obligations to Qwest under this Agreement.  Qwest's obligation
     to assist under this Section 8.3 shall not include payments to Customer or
     any third party in connection with such transition.

9.   GOVERNMENTAL AUTHORITY
     ----------------------

9.1  Customer acknowledges that the obligation of Qwest to provide the
     Facilities to Customer is subject to the receipt by Qwest of any required
     regulatory or other governmental authorizations.  Qwest reserves the right
     to terminate this Agreement pursuant to Section 8.2 of this Agreement if at
     any time Qwest loses the required regulatory or other governmental
     authorizations to provide the Facilities (a "Regulatory Change").  To the
     extent required by law, this Agreement may be superseded and/or
     supplemented by a tariff filed with the appropriate regulatory agency,
     which tariff may contain such modifications of the provisions of this
     Agreement as Qwest deems appropriate, all of which shall become
     automatically binding on Customer.  Such a tariff shall be filed only if
     required by applicable law, and, in such event, Customer shall be

                                       5
<PAGE>

     entitled to terminate this Agreement immediately as to the affected Service
     Order(s) in the event a material term of this Agreement is superseded by
     said tariff filing.

9.2  Each party represents and warrants that:  (a) it  has received all
     necessary permits, licenses, approvals, grants, and charters of whatsoever
     kind necessary to carry out the business in which it  is engaged hereunder;
     and (b) it has complied and is in material compliance with all laws,
     regulations, orders, and statutes which may be applicable to it, whether
     local, State or Federal.  From the date of this Agreement until the
     termination hereof, each party  agrees to operate in accordance with and to
     maintain current all such certifications, permits, licenses, approvals,
     grants, charters, and to materially comply with all applicable laws,
     regulations, orders and statutes, whether local, State or Federal.  A
     failure to cure a breach by either Party of any of the representations,
     warranties or covenants of this Section 9.2 within thirty (30) calendar
     days of receipt of written notice from the other party shall be deemed a
     Default hereunder, and shall allow the other party  to terminate the
     affected portion of the Facilities, or in the case of all or substantially
     all of the Facilities being affected, this Agreement, in the manner
     described in Section 8 of this Agreement. A Regulatory Change not within
     Qwest's reasonable control shall not constitute a default under this
     Section 9.2. In addition, Qwest reserves the right to suspend its
     performance under this Agreement during the pendency of Customer's cure
     efforts.

10.  FORCE MAJEURE
     -------------

10.1 Except as is provided in Section 10.2 below, Qwest shall not be liable for
     any failure of  performance hereunder due to causes beyond its reasonable
     control, including, but not limited to:  acts of God, fire, explosion,
     vandalism, fiber optic cable cut, storm, extreme temperatures or other
     similar catastrophes; any law, order, regulation, direction, action or
     request of the United States government, or of any other government,
     including state and local governments having  jurisdiction over either of
     the parties, or of any department, agency, commission, court, bureau,
     corporation or other instrumentality of any one or more said governments,
     or of any civil or military authority; national emergencies, insurrections,
     riots, wars, or strikes, lock-outs, work stoppages or other labor
     difficulties; actions or inactions of a third party provider or operator of
     facilities employed in provision of the Facilities; or any other conditions
     or circumstances beyond the reasonable control of Qwest which impede or
     affect the Facilities or the transmission of telecommunications services.

10.2 If any failure of performance on the part of Qwest described in Section
     10.1 of this Agreement shall be:  (a) for thirty (30) calendar days or
     less, then this Agreement shall remain in effect, but Customer shall be
     relieved of its obligation to pay for that portion of the Facilities
     affected for the period of such failure of performance; or (b) for more
     than thirty (30) days, then Customer may terminate without liability (other
     than charges accrued but unpaid applicable to the terminated Service
     Order(s)) only that portion of any Service Order or Service Orders related
     to the Facilities so affected, upon ten (10) calendar days prior written
     notice to Qwest following the failure of performance.

                                       6
<PAGE>

10.3 If the Facilities are unavailable to Customer as a result of any events
     described in Section 10.1, Customer will be entitled to an Outage Credit
     under Section 5 of the Service and Pricing Exhibit.

11.  YEAR 2000
     ---------

     Qwest shall use commercially reasonable efforts to ensure that its internal
     operating and network systems are designed to operate during calendar year
     2000 A.D. without material error or interruption relating to date data
     (including, without limitation, date data which represents or references
     different centuries or more than one century or leap year) in any level of
     the systems assuming, in each case, that all systems and products used in
     combination with them properly exchange data (hereinafter referred to as
     "Year 2000 Compliant").  If Qwest's system causes an outage due to the
     system's failure to be Year 2000 Compliant, ("Year 2000 Outage") Customer
     shall receive credits in accordance with Section 5 of the Service and
     Pricing Exhibit.  If the Year 2000 Outage continues for thirty (30) days,
     Customer may (a) terminate this Agreement provided that such Year 2000
     Outage affects all or substantially all Facilities provided by Qwest under
     this Agreement; or (b) terminate any affected Service Order(s).
     Termination under this Section 11 shall be effected without liability for
     early termination charges or shortfall charges, and such termination shall
     be Customer's sole and exclusive remedy.

12.  ASSIGNMENT
     ----------

     Neither party may sell, assign, sublet, encumber or transfer this Agreement
     or any of its rights or obligations hereunder, except to a direct or
     indirect wholly owned subsidiary of such party, by operation of law or
     otherwise (hereafter, a "Transfer"), without the prior written consent of
     other party hereto, which consent shall not be unreasonably withheld.  Any
     Transfer by either party without the other party's prior written consent
     shall entitle the non-transferring party, at its option, to:  (a) consider
     the Transfer void; (b) consent to the Transfer, and hold the transferring
     party and any transferee(s) liable hereunder; or (c) terminate this
     Agreement upon delivering written notice to the transferring party.
     Subject to the foregoing, this Agreement shall be binding upon and inure to
     the benefit of the parties hereto and their respective successors or
     assigns.

13.  TITLE
     -----

     Customer expressly disclaims any right, title, perpetual right of use or
     any other interest in or to any equipment or property provisioned or
     supplied by Qwest under this Agreement.

14.  WARRANTIES AND LIMITATION OF LIABILITY
     --------------------------------------

14.1 Qwest warrants that the Facilities shall be provided to Customer and shall
     operate in accordance with the then current prevailing telecommunications
     industry standards (hereinafter the "Technical Standards").  If Qwest
     determines that the Facilities are not being provided in accordance with
     the Technical Standards (hereinafter, a "Defect" or

                                       7
<PAGE>

     "Defects"), Qwest shall use reasonable efforts to conform the Facilities to
     the Technical Standards.

14.2 THE WARRANTIES CONTAINED IN SECTION 14.1 OF THIS AGREEMENT ARE EXCLUSIVE
     AND IN LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY,
     INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY OR
     FITNESS FOR A PARTICULAR PURPOSE.  QWEST HEREBY SPECIFICALLY DISCLAIMS ANY
     LIABILITY TO CUSTOMER FOR INTERRUPTIONS AFFECTING THE FACILITIES FURNISHED
     HEREUNDER WHICH ARE ATTRIBUTABLE TO CUSTOMER'S INTERCONNECTION FACILITIES
     (AS DEFINED IN SECTION 1.4 OF THE SERVICE AND PRICING EXHIBIT) OR TO
     CUSTOMER'S EQUIPMENT FAILURES, OR TO CUSTOMER'S BREACH OF THIS AGREEMENT.

14.3 IN NO EVENT SHALL QWEST OR ANY OF ITS AFFILIATES BE LIABLE TO CUSTOMER OR
     ANY OF ITS AFFILIATES OR EMPLOYEES OR TO ANY THIRD PARTY FOR:  (a) ANY LOSS
     OF PROFIT OR REVENUE, OR FOR ANY INDIRECT, CONSEQUENTIAL, INCIDENTAL,
     PUNITIVE OR SIMILAR OR ADDITIONAL DAMAGES, WHETHER INCURRED OR SUFFERED AS
     A RESULT OF UNAVAILABILITY OF FACILITIES, PERFORMANCE, NON-PERFORMANCE,
     TERMINATION, BREACH, OR OTHER ACTION OR INACTION UNDER THIS AGREEMENT, OR
     FOR ANY OTHER REASON, EVEN IF CUSTOMER ADVISES QWEST OF THE POSSIBILITY OF
     SUCH LOSS OR DAMAGE; OR (b) FOR ANY OUTAGE OR INCORRECT OR DEFECTIVE
     TRANSMISSIONS, OR ANY DIRECT OR INDIRECT CONSEQUENCES THEREOF, EXCEPT AS IS
     SPECIFICALLY PROVIDED IN SECTION 5 OF THE SERVICE AND PRICING EXHIBIT
     REGARDING OUTAGE CREDITS.

14.4 NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY:  (a) CUSTOMER
     AGREES THAT ITS SOLE REMEDY IN THE EVENT OF ANY BREACH OF THE WARRANTIES
     DESCRIBED IN SECTION 14.1 OF THIS AGREEMENT SHALL BE THE OUTAGE CREDITS
     DESCRIBED IN SECTION 5 OF THE SERVICE AND PRICING EXHIBIT; AND, (b) IN NO
     EVENT SHALL THE CUMULATIVE LIABILITY OF QWEST UNDER THIS AGREEMENT,
     INCLUDING ANY OUTAGE CREDITS, EXCEED THE TOTAL PAYMENTS PAID BY CUSTOMER TO
     QWEST HEREUNDER.

14.5 Customer acknowledges that Qwest has no ability to independently test or
     maintain Facilities between two off net cities.  Consequently, if Qwest
     provides such Facilities, then notwithstanding anything in this Agreement
     to the contrary, Qwest's entire duty with respect to such Facilities shall
     be to use its best efforts to test and maintain such Facilities in
     accordance with Qwest's Specifications.

15.  NON-DISCLOSURE AND PUBLICITY
     ----------------------------

                                       8
<PAGE>

15.1 The parties agree that this Agreement is and shall be kept confidential.
     Neither party shall divulge or otherwise disclose any of the provisions of
     this Agreement to any third party without the prior written consent of the
     other party, except that either party may make disclosure to those required
     for the implementation of this Agreement, and to purchasers and prospective
     purchasers of their respective companies, auditors, attorneys, financial
     advisors, lenders and prospective lenders, investors and prospective
     investors, provided that in each case the recipient agrees in writing to be
     bound by the confidentiality provisions set forth in this section. In
     addition, either party may make disclosure as required by a court order or
     as otherwise required by law, securities exchange or SEC rules or
     regulations, or in any legal or arbitration proceeding relating to this
     Agreement.  If either party is required by law or by interrogatories,
     requests for information or documents, subpoena, civil investigative demand
     or similar process to disclose the provisions of this Agreement, it will
     provide the other party with prompt prior notice of such request or
     requirement so that such party may seek an appropriate protective order
     and/or waive compliance with this Section.  The party whose consent to
     disclose information is requested shall respond to such request, in
     writing, within five (5) business days of the request by either authorizing
     the disclosure or advising the other party of its election to seek a
     protective order, or if such party fails to respond within the prescribed
     period the disclosure shall be deemed approved.

15.2 Each party shall submit to the other party all news releases, advertising
     and other publicity material related to this Agreement wherein the second
     party's name is mentioned or language is used from which a connection to
     such second party's name therein may, in such second party's judgment, be
     inferred or implied.  Neither party shall publish or use such material or
     use the other party's name, without the prior written consent of such
     second party.

16.  ARBITRATION
     -----------

16.1 All disputes which involve amounts reasonably anticipated to be in excess
     of Twenty-Five Thousand Dollars ($25,000.00) arising out of or related to
     this Agreement, shall be determined and resolved by arbitration in San
     Francisco, California, in accordance with the rules of the American
     Arbitration Association ("AAA").  The arbitrators shall be appointed in
     accordance with the rules then prevailing of the AAA.

16.2 The award rendered by the arbitrator(s) shall be final and binding upon the
     parties hereto.  Neither party shall have the right to further appeal or

     award may be entered and enforced in any court of competent jurisdiction.

16.3 The parties hereto agree that a prevailing party shall be entitled to
     recover all reasonable costs and expenses (including all reasonable
     attorneys' fees and disbursements) of such arbitration proceeding.  Such
     prevailing party shall also be entitled to reasonable attorneys' fees and
     costs incurred in enforcing a judgment of the arbitrators separately from
     and in addition to any other amount included in such judgment.  This
     Section 16.3

                                       9

                             QWEST COMMUNICATIONS
                        PRIVATE LINE SERVICES AGREEMENT

     SERVICE AND PRICING EXHIBIT
     ---------------------------

     This Service and Pricing Exhibit (this "Service and Pricing Exhibit") is
     made as of June 1, 1999 by and between Qwest Communications Corporation, a
     Delaware corporation ("Qwest"), and Advanced Radio Telecom Corp., a
     Delaware corporation ("Customer"), with respect to that certain Private
     Line Services Agreement entered into by and between Qwest and Customer on
     June 1, 1999 (the "Agreement").

1.   QWEST SERVICES:
     --------------
1.1  During the Term of the Agreement, Qwest will provide to Customer the
Facility or Facilities requested by Customer in a Service Order accepted by
Qwest.

1.2  Upon acceptance of a Service Order, Qwest shall notify Customer of its
target date for the delivery of each Facility (the "Estimated Availability
Date"). Any Estimated Availability Date given by Qwest to Customer shall be
subject to Qwest's standard and expedited interval guidelines, as amended by
Qwest from time to time. Qwest shall use reasonable efforts to install each such
Facility on or before the Estimated Availability Date, but the inability of
Qwest to deliver a Facility by such date shall not be a Default under this
Exhibit. If Qwest fails to make any Facility available within ninety (90) days
after acceptance by Qwest of the Service Order with respect to such Facility (or
such greater time as is set forth in the accepted Service Order(s)), Customer's
sole remedy shall be to cancel the Service Order which pertains to such Facility
by fifteen (15) calendar days prior written notice to Qwest.

1.3  At each end of the city pairs (the "City Pairs") on which Customer orders
Facilities, Qwest shall provide appropriate equipment in its terminal locations
necessary to connect the Facilities to Customer's Interconnection Facilities (as
defined in Section 1.4 of this Service and Pricing Exhibit). If Customer desires
to install its own equipment in one or more of Qwest's terminals, and Qwest, in
its sole discretion, agrees to such installation, the parties shall execute the
Collocation Exhibit.

1.4  Customer agrees that Customer's Interconnection Facilities shall connect to
the Facilities provided by Qwest hereunder at the network interface points
located in the Qwest terminals and defined in the Specifications (as defined in
Section 2.1 of this Service and Pricing Exhibit). As used herein, the term
"Interconnection Facilities" shall mean transmission capacity provided by
Customer or its third party supplier to extend the Facilities provided by Qwest
from a Qwest terminal to any other location (e.g., a local access telephone
service provided by a local telephone company).

1.5  For DS-3 Facilities and above, if requested by Customer, Qwest shall use
reasonable efforts to order Interconnection Facilities on behalf of Customer
from Customer's designated supplier, provided that Customer furnishes Qwest with
an acceptable letter of agency. Customer

                                       1
<PAGE>

shall be billed directly by the supplier of such Interconnection Facilities, and
shall hold harmless and indemnify Qwest from any loss or liability incurred by
Qwest as a result of Qwest's ordering such Interconnection Facilities from any
third party. Customer may, at its election, but subject to Qwest's prior written
approval, order its own Interconnection Facilities. If any party other than
Qwest provides Interconnection Facilities, then unavailability, incompatibility,
delay in installation, or other impairment of Interconnection Facilities shall
not excuse Customer's obligation to pay Qwest all Rates or charges applicable to
the Facilities, whether or not such Facilities are useable by Customer.

2.   START OF SERVICES:
     -----------------

2.1  Start of service for each Facility (the "Start of Service Date") shall
begin on the date on which Customer accepts delivery of such Facility. If
Customer fails to give written notice that the Facility is in material
non-compliance with the applicable standard Qwest network specifications, as
modified from time to time by Qwest (the "Specifications") within ten (10)
business days after notification to Customer by Qwest that the Facility is
available, Customer shall be deemed to have accepted such Facility, and the
Start of Service Date shall commence as of the fifth day following such
notification by Qwest. Following notice by Customer of material non-compliance
as set forth above, Qwest shall promptly take such reasonable action as is
necessary to correct any such non-compliance in the Facility and shall, upon
correction, notify Customer of a new Start of Service Date.

2.2  Notwithstanding anything in Section 2.1 of this Service and Pricing Exhibit
to the contrary, Customer may delay the Start of Service Date for any Facility
for up to thirty (30) days from Qwest's Estimated Availability Date by written
notice to Qwest at least three (3) business days prior to any applicable
Estimated Availability Date.

3.   RATES:
     -----

3.1  Except as otherwise provided in a special rate exhibit attached to the
Agreement, Qwest shall provide the Facilities at the rates (the "Rates") set
forth in this Section 3 (exclusive of all sales, use, commercial or other taxes
or license fees) and as shown on the Circuit Listing attached as Schedule A-1 to
this Service and Pricing Exhibit.  The Rates for the Facilities apply to the
Inter-Office Channel ("IOC") of the On-Net circuit specified from the nearest
originating Qwest owned Point of Presence ("POP") to the nearest terminating
Qwest owned POP.  Customer shall be responsible for all interconnection costs
from the customer location indicated by the Originating NPA/NXX and the
Terminating NPA/NXX to the corresponding Qwest owned POP.  A circuit shall be
considered "On-Net" when a dedicated leased line IOC circuit is provisioned (i)
entirely between two Qwest owned Domestic U.S. POPs lying on Qwest owned fiber
optic lines, and (ii) utilizes only Qwest owned fiber optic lines.  The Rates
vary depending on whether the Facilities are DS-1 or DS-3 or OC-n.  The Rates,
Monthly Recurring Charges ("MRCs") and Non-Recurring Charges ("NRCs") for Qwest
On-Net Domestic US dedicated leased line service are as follows:

     and Pricing Exhibit applicable to any new Facility or Facilities ordered by
     Customer.

4.   FACILITY MINIMUM SERVICE TERM:
     -----------------------------

4.1  Customer acknowledges that the Rates and charges described in Section 3
of this Service and Pricing Exhibit are based on the commitment of Customer to
utilize the Facilities for a specified minimum period of time.  Therefore,
notwithstanding anything in this Exhibit to the contrary, Customer shall be
liable for and shall pay to Qwest all Rates, fees and charges which accrue under
this Exhibit for each Facility for the entire Facility Minimum Service Term (as
defined in Section 4.2 of this Service and Pricing Exhibit) applicable to each
such Facility, regardless of whether or not Customer utilizes all or any part of
such Facility during all or any part of the Facility Minimum Service Term
applicable to such Facility, except as is set forth in Section 4.3 of this
Service and Pricing Exhibit.

<PAGE>

4.3  Notwithstanding anything in this Service and Pricing Exhibit to the
contrary, Customer's obligation to pay all Rates, fees and charges applicable to
any particular Facility, including but not limited to any obligation to pay the
applicable MRC [*
          ] associated with said Facility hereunder shall terminate as to each
Facility authorized to be terminated without penalty pursuant to the Agreement.
UPON TERMINATION OF THIS AGREEMENT FOR ANY OTHER REASON, THE TOTAL OF ALL

REGARDLESS OF WHETHER OR NOT ALL OF THE FACILITIES MINIMUM SERVICE TERMS HAVE
EXPIRED, AND MAY BE COLLECTED BY QWEST FROM CUSTOMER AS A SINGLE AMOUNT.

5.   OUTAGE CREDITS:
     --------------

5.1  Customer acknowledges the possibility of an unscheduled, continuous
and/or interrupted period of time when a Facility or Facilities are
"unavailable" (as defined in the Specifications) (hereafter an "Outage").  In
the event of an Outage, Customer shall be entitled to a credit (the "Outage
Credit") determined according to the following formula:

[*


                                        ]

5.2  The Outage Credit shall apply to the charges for the total mileage between
end terminals of any Facility affected by an Outage; provided, however, that if
any portion of the affected Facility remains beneficially used or useable by
Customer between any intermediate terminals (where Customer has installed drop
and insert capability) or end terminals, the Outage Credit shall not apply to
that pro-rata portion of the mileage. The length of each Outage shall be
calculated in hours and shall include fractional portions thereof. An Outage
shall be deemed to have commenced upon verifiable notification thereof by
Customer to Qwest, or, when indicated by network control information actually
known to Qwest network personnel, whichever is earlier. Each Outage shall be
deemed to terminate upon restoration of the affected Facility as evidenced by
appropriate network tests by Qwest. Qwest shall give reasonable notice to
Customer of any scheduled outage, and a scheduled outage shall under no
circumstance be viewed as an Outage hereunder.

5.3  Outage Credits shall not be granted if the malfunction of any end-to-end
circuit is due to an Outage or other Defect occurring in Customer's
Interconnection Facilities.


5.4  All Outage Credits shall be credited on the next monthly invoice for the
affected Facility after receipt of Customer's request for credit. The total of
all Outage Credits applicable to or accruing in any given month shall not exceed
the amount payable by Customer to Qwest for that same month for such Facility.

Exhibit shall be the sole and exclusive remedy of Customer in the event of any
Outage, and under no circumstance shall an outage be deemed a Default under this

     .  MTTR for SONET equipment: 2 hours
     .  MTTR for fiber optic cable: 12 hours (Bellcore Standard)
     .  Cable cut rate: 4.39 /year/1,000 sheath miles (Bellcore Standard)

The system includes three (3) DCS in Los Angeles, Sacramento, and San Jose
(although not all circuits are routed through the DCS, they are included in all
the calculations)

2.2  Availability is a measure of the relative amount of time during which the
circuit is available for use. According to CCITT and ANSI definitions,
unavailability begins when the Bit Error Ratio (BER) in each second is worse
than 1.0 E-3 for a period of 10 consecutive seconds.

                    QWEST PRIVATE LINE SERVICE DESCRIPTION

Inter Office Channel (IOC) : An Inter Office Channel refers to the Qwest
Communications network between the points of presence (POP).

Optical Carrier level 1 (OC-1) : The optical signal that results from an
optical conversion of an electrical STS-1 signal (51.840 Mb/s).  This signal
forms the basis of the interface.

OC-3: Optical Carrier level 3 signal operating at 155.520 Mb/s.

OC-12: Optical Carrier level 12 signal transmitting at 622.080 Mb/s.

OC-48: Optical Carrier level 48 signal transmitting at 2488.32 Mb/s.


Point of Presence (POP): A physical location where a long distance carrier
terminates lines before connecting to the local exchange carrier, another
carrier, or directly to a customer.

2.3  The availability objective for all circuits between Qwest Network Interface
points specified above is to provide performance levels over a 12 month period
as follows:

-------------------------------------------------------------
V&H Miles                   DS1, DS3, OC-3, OC-12, OC-48,
                            OC-3c, OC-12c, and OC-48c
-------------------------------------------------------------
     0-2500                        [*          ]
-------------------------------------------------------------
   2501-4000                       [*          ]
-------------------------------------------------------------

     This excludes any customer provided access links to the Qwest digital
network.

2.4  Outages attributable to incidental damage to or severage of outside fiber
optic cable plant, or scheduled maintenance is excluded from the performance
objective stated above.

2.5  Error-Free Seconds (EFS) and Error Seconds (ES) are the primary measure of
error performance.  An Error-Free Second is defined as any second in which no
bit errors are received.  Conversely, an Error Second is any second in which one
or more bit errors are received.

3.   SONET : Synchronous Optical Network  is a family of optical transmission
rates and interface standards allowing internetworking of products from
different vendors.  Base optical rate is 51.840 Mb/s.  Higher rates are direct
multiples.

SONET Transport : Facilities associated with carrying OC-1 or higher level
signals.

                    QWEST PRIVATE LINE SERVICE DESCRIPTION

Synchronous Transport Signal level 1 (STS-1) : The basic logical building block
electrical signal with a rate of 51.840 Mb/s.

Synchronous Transport Signal level N (STS-N) : This electrical signal is
obtained by byte interleaving N STS-1 signals together.  The rate of the STS-N
is N times 51.840 Mb/s.

Terminating Multiplex (TM) : Provides the multiplex functions for multiplexing
and demultiplexing between the DS1 or higher signal level and the SONET OC-N
level.

4.   Acceptance Criteria. The acceptance criteria for DS1, DS3, OC-3, OC-12, OC-
48, OC-3c, OC-12c, and OC-48c circuits between Qwest Network Interface points is
to provide the performance levels shown below during a 60 minute test period. If
no errors are observed during the first 15 minutes of the test, the facility may
be considered acceptable. Access connections to customer location will be tested
in accordance with Bell Publication 62508.

 .  The tables below are based on QCC owned fiber optic network only and on the
Bellcore Specifications of the SONET delivery of DS1, DS3, OC-3, OC-12, OC-48,
OC-3c, OC-12c, and OC-48c directly off the SONET Backbone.

 .  If the DS1, DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c service is
delivered at the STS1 level then the general performance objectives fall into
the industry standard.

DS1, DS3
The table below defines the general performance objectives for DS1 service
operating at 1.544 Mb/s, and the general performance objectives for DS3 service
operating at 45 Mb/s.
