</TABLE>

        This Addendum VI (this "ADDENDUM"), dated as of February 21, 2001 (the
"ADDENDUM DATE"), contains certain additional and supplemental terms and
provisions to that certain Sprint PCS Management Agreement entered into as of
October 15, 1998, by UbiquiTel L.L.C. (but subsequently transferred to
UbiquiTel Operating Company) (the "MANAGER"), Sprint Spectrum L.P.,
WirelessCo, L.P. and Sprint Communications Company, L.P., which Management
Agreement was further amended by certain addenda (the Management Agreement, as
amended by Addendum I, Addendum II, Addendum III, Addendum IV and Addendum V,
being the "MANAGEMENT AGREEMENT"). This Addendum (and its modification of the
Management Agreement) becomes effective upon the consummation of the proposed
acquisition by Manager of indirect control of VIA Wireless, LLC ("VIA") in the
transaction to which Sprint PCS consented on February 20, 2001 (such
consummated transaction being the "MERGER", and the effective date of the
Merger and of this Addendum being the "EFFECTIVE DATE"). If the Merger is not
consummated for any reason (the date on which the Merger is abandoned,
terminated or cancelled, or for any other reason determined it will not be
consummated, being the "TERMINATION DATE"), this Addendum shall be void and
have no further force and effect. Notwithstanding the Effective Date and the
Termination Date described in the two preceding sentences, the terms of
paragraphs 2, 3, 5, 8, 9, 10, 11, 12 and 13 below become effective upon the
Addendum Date, and the terms of paragraphs 8, 9, 10 and 11 will remain in full
force and effect between the parties to this Addendum after the Termination
Date.

        The terms and provisions of this Addendum, as of the Effective Date
(or as of the Addendum Date, as the case may be), will control, supersede and
amend any conflicting terms and provisions contained in the Management
Agreement. Except for express modifications made in this Addendum, the
Management Agreement continues in full force and effect. Capitalized terms
used and not otherwise defined in this Addendum have the meanings ascribed to
them in the Management Agreement. Section and Exhibit references are to
Sections of, and Exhibits to, the Management Agreement, unless otherwise noted.

        The Management Agreement is modified as follows effective as of the
Effective Date or the Addendum Date, as the case may be:

        1.      TYPE II CONVERSION SCHEDULE AND COSTS. If VIA has not
completed the conversion (the "TYPE II CONVERSION") of its Service Area
Network (the "VIA SERVICE AREA NETWORK") from Type III (I.E., where VIA
designates Option #3 on Exhibit 2.1.2 to the Services Agreement) to Type II
(I.E., where VIA designates Option #2 on Exhibit 2.1.2 to the Services
Agreement) by the Effective Date, Manager agrees to complete such conversion
no later than July 8, 2001 (PROVIDED, that if Manager's failure to complete
the Type II Conversion by such date results primarily from Sprint PCS' failure
to perform all items necessary on its part, Manager may

                                        2

claim that an event under Section 17.9.3 has occurred), or such other date as
may be mutually agreed upon between Manager and Sprint PCS. Sprint PCS will
pay for the actual costs Sprint PCS incurs to input customer information for
customers with Manager's NPA-NXXs (or VIA's NPA-NXXs if the Type II Conversion
has not been completed by the Effective Date) in the six BTAs that constitute
VIA's Service Area (the "VIA SERVICE AREA") into Sprint PCS' billing system
and for Sprint PCS' employee resources to facilitate the Type II Conversion.
Manager will be responsible for the payment of all other costs, including (i)
the actual costs Manager and VIA incur to migrate customer information from
Manager's or VIA's billing system to Sprint PCS' billing system, (ii) any
incremental costs incurred by Sprint PCS resulting from any non-standard Type
II Conversion activities (E.G., additional customer care calls) or incremental
support unique to pricing plans established by VIA (E.G., additional fields on
billing records), and (iii) other costs incurred by Manager and VIA in
implementing and maintaining a Type II network.

        2.      SPECTRUM TRANSITION. On the Effective Date, Manager and VIA
will complete the transition of the operation of the VIA Service Area Network
from using the FCC licenses held by VIA or its Related Parties to using the
PCS Spectrum described on the SERVICE AREA EXHIBIT attached to this Addendum
(the "SPECTRUM TRANSITION"). Manager agrees to complete the Spectrum
Transition at its sole expense (except as provided below in paragraph 9).
Manager will not consummate the Merger until it completes the Spectrum
Transition. To effect the Spectrum Transition (a) the Affiliation Agreement
entered into in January, 1999, between VIA (f/k/a Central Wireless
Partnership) and Sprint PCS, as amended (the "VIA AFFILIATION AGREEMENT") and
all other agreements with Sprint PCS and its Related Parties to which VIA is a
party will be terminated (although VIA and Manager will continue to be
responsible for any pre-termination liabilities and obligations under the VIA
Affiliation Agreement and all such other agreements), (b) the VIA Service Area
Network will become part of the Service Area Network under the Management
Agreement, and (c) the VIA Service Area will become part of the Service Area
under the Management Agreement as described on the SERVICE AREA EXHIBIT
attached to this Addendum.

        3.      DISCONTINUATION OF UNLIMITED PLANS. If VIA has not already
done so, Manager and Sprint PCS agree that Manager will cease on or before the
sixtieth (60 th ) day after the Addendum Date (or such later date as the
Manager and Sprint PCS may mutually agree) (the "UNLIMITED PLAN TERMINATION
DATE") to promote and sell in the VIA Service Area any pricing plans with
unlimited minutes of use or availability in specific area codes only that are
not included as part of the Sprint PCS national pricing plan offer (E.G., VIA
Plus Plans and Unlimited Plus Plans). Sprint PCS will provide billing support
to customers who activated under such plans on or before the Unlimited Plan
Termination Date, until all such customers change to a Sprint PCS national or
regional pricing plan or discontinue Sprint PCS service.

        4.      COMPLETION OF VIA SERVICE AREA BUILD-OUT REQUIREMENT. Manager
will, on or before September 1, 2001, complete the build-out requirements for
the VIA Service Area as set forth on EXHIBIT 2.1.1 (taking into account the
coverage footprint map, the Pops analysis table and the narrative description
of the build-out) (the "VIA SERVICE AREA BUILD-OUT REQUIREMENT"), except for
the following exceptions, each of which Manager agrees to complete the
build-out within a commercially reasonable period: (a) to the extent Manager's
failure to complete any portion of the build-out results primarily from one of
the events described in Section 17.9.3; or (b) Manager may complete after
September 1, 2001, construction of not more than three of the cell sites
needed to provide coverage for Mendota (Fresno BTA); Orosi, Woodlake,

                                        3
<PAGE>

Dinuba and Kingsburg (Visalia-Porterville-Hanford BTA); Shafter and Wasco
(Bakersfield BTA); Atwater and Winton (Merced BTA); and due east of Ceres
along Highway 99 northwest to J7 to include Hughson, Empire, Hickman and
Waterford (Modesto BTA); or (c) the cell site that needs to be located on land
owned by Tejon Corporation to provide coverage along I-5 to meet Sprint PCS
coverage at the southern Bakersfield BTA border. If Manager delivers to Sprint
PCS, within 10 days after the Addendum Date, copies of the original documents
that VIA delivered to Manager to disclose the status of all current and
planned cell sites, then to the extent Manager verifies to Sprint PCS that a
material discrepancy exists between the documents delivered to Sprint PCS and
the actual status of such cell sites, Sprint PCS will give Manager a
commercially reasonable period of time to complete the build-out taking into
consideration the level of such material discrepancy. Subject to the
limitation set forth below in paragraph 5 of this agreement, if Manager does
not complete the VIA Service Area Build-out Requirement as described in this
paragraph 4, Sprint PCS may declare an Event of Termination under the
Management Agreement, and Manager waives any right to a cure period under the
Management Agreement.

        5.      NO DECLARATION OF BREACH. Sprint PCS agrees that until
September 1, 2001, it will not declare VIA or Manager in breach of the VIA
Affiliation Agreement or the Management Agreement, as the case may be, based
on their respective failure to complete any of the VIA Service Area Build-out
Requirement; PROVIDED, that Sprint PCS' agreement to not declare VIA in breach
of the VIA Affiliation Agreement under this paragraph 5 terminates on the
Termination Date.

        6.      REVISED FINANCING PLAN. EXHIBIT 1.7 attached to this Addendum
supersedes and replaces in its entirety EXHIBIT 1.7 attached to the Management
Agreement.

        7.      REVISED BUILD-OUT PLAN. At the time of the Spectrum
Transition, EXHIBIT 2.1.1 attached to this Addendum will be made part of
Manager's existing EXHIBIT 2.1 attached to the Management Agreement expressly
subject to the terms, conditions and provisions of paragraph 4 above.

        8.      EXCLUSIVITY OF SERVICE AREA. In Section 2.3 and the Schedule
of Definitions, the phrase "wireless mobility communications network" is
replaced by the phrase "Wireless Mobility Communications Network".

        9.      MICROWAVE RELOCATION. Manager requests that Sprint PCS begin
clearing PCS Spectrum in the VIA Service Area in the manner described in
Section 2.7, even though the VIA Service Area is not yet part of the Service
Area. Manager and Sprint PCS will share all costs (including costs incurred or
for which Sprint PCS becomes obligated prior to the Effective Date) related to
clearing such PCS Spectrum. If the Merger is not consummated for any reason,
Manager agrees to reimburse Sprint PCS for all costs Sprint PCS incurs or for
which Sprint PCS becomes obligated in connection with clearing such PCS
Spectrum after the Addendum Date and prior to the Termination Date.

        10.     NOTICE OF MERGER TERMINATION. Manager agrees to give Sprint
PCS written notice that the proposed Merger has been abandoned, terminated,
cancelled or will not be consummated for any reason, within one business day
after the Termination Date.

                                        4

                             EXHIBIT 1.7 (Amended)
                    BUILD-OUT AND WORKING CAPITAL FINANCING

This Amended Exhibit 1.7 sets forth the build-out and working capital
financing for the expansion of the Service Area under the Management Agreement
to include the BTAs included within the VIA Service Area (as defined in
Addendum VI to the Management Agreement), specifically including BTA No. 28
(Bakersfield), BTA No. 157 (Fresno), BTA No. 291 (Merced), BTA No. 303
(Modesto), BTA No. 434 (Stockton), and BTA No. 158 (Visalia-Porterville-Hanford)
(the "VIA Expansion"), along with the build-out and working capital financing
for the existing Service Area of Manager (prior to the VIA Expansion).  The
combined Equity, Senior Debt and Subordinated Debt as described below will
provide the necessary working capital to meet the build-out and working
capital requirements of the VIA Expansion and to operate the entirety of the
business through cash flow break even.  Expected uses of funds through cash
flow break even (year 2003) for the combined existing Service Area of the
Manager (prior to the VIA Expansion) and the VIA Expansion are as follows:

only as the surviving corporation in a merger with Merger Sub V), and their
respective directors, officers, employees, agents, advisors, attorneys,
accountants, and consultants (collectively, the "UbiquiTel Indemnitees"), from
and against, and promptly reimburse the UbiquiTel Indemnitees for, any loss,
expense, damage, deficiency, liability, claim or obligation, including
investigative costs, costs of defense, settlement costs, and attorneys' and
accountants' fees (collectively, "Losses") that any UbiquiTel Indemnitee
suffers or incurs or to which any UbiquiTel Indemnitee becomes subject,
whether arising before or after the Effective Time, which Losses arise out of
or in connection with or relate to the activities and business of Evans (other
than the business of CVC) prior to the Effective Time, including without
limitation any and all claims by third parties (governmental or private) for
business torts, breach of contract, and claims for malicious or intentional
misconduct, fraud, personal injury, property damage, worker's compensation,
and Taxes. For the avoidance of doubt, the indemnification obligations
provided by this Agreement do not extend to losses arising out of the business
and operations of the LLC. Notwithstanding the foregoing, the Evans
Stockholders shall be responsible for Taxes only to the extent such Taxes (i)
have not been paid by Evans on or before the Closing Date, and (ii) have not
been taken into account in computing Net Assets pursuant to Section
1.2(b)(ii)(B) of the Merger Agreement or the Tax Return adjustment amount
pursuant to Section 1.2(b)(ii)(B)(III) of the Merger Agreement.

         2.       SHARE OF LIABILITY. If any Evans Stockholder ("Paying
Stockholder") is required to pay or is held liable for any amount with respect
to an indemnified claim, each of the other Evans Stockholders ("Remaining
Evans Stockholders") shall be liable to the Paying Stockholder for, and shall
contribute to and hold the Paying Stockholder harmless from and against, an
amount equal to such Stockholder's proportionate share of such liability
(based upon the aggregate dollar value of the Merger Consideration received by
such Stockholder pursuant to the Merger Agreement) as adjusted to account for
a default by any Stockholder in meeting its obligations hereunder. Any such
amounts shall be paid within five days of the date any Paying Stockholder is
held liable for, or is required to pay, an indemnified claim.

         3.       PAYMENTS. All indemnification payments made under this
Agreement shall be made to UbiquiTel and deemed adjustments to the Merger
Consideration received by the Evans Stockholders.

         4.       EXCLUSIVITY. In the absence of fraud, the indemnification
provisions of this Agreement shall be the exclusive remedy for any Losses.

         5.       NOTICE AND OPPORTUNITY TO DEFEND.

                  (a)      NOTICE, ETC. If a UbiquiTel Indemnitee receives
notice of any third-party claim or commencement of any third-party action or
proceeding (an "Asserted Liability") with respect to which the Evans
Stockholders are obligated to provide indemnification pursuant to this
Agreement, such UbiquiTel Indemnitee shall promptly give all Evans
Stockholders notice thereof. The failure of a UbiquiTel Indemnitee so to
notify an Evans Stockholder shall not cause any UbiquiTel Indemnitee to lose
its rights to indemnification under this Agreement, except to the extent that
such failure materially prejudices an Evans Stockholder's ability to defend
against an Asserted Liability that such Evans Stockholder has the right to
defend against hereunder (and except as otherwise set forth in this
Agreement). Such notice shall describe the Asserted Liability in reasonable
detail, and if practicable shall indicate the amount (which may be estimated)
of the Losses that have been or may be asserted by a UbiquiTel Indemnitee.
Upon receiving such written notice, each of the Evans Stockholders shall
defend against the Asserted Liability on behalf of a UbiquiTel Indemnitee
using counsel selected by Evans Stockholders, unless (i) the UbiquiTel
Indemnitee reasonably objects to the assumption of such defense on the grounds
that counsel for such Evans Stockholder cannot represent both such UbiquiTel
Indemnitee and such Evans Stockholder because such representation would be
reasonably likely to result in a conflict of interest or because there may be
defenses available to such UbiquiTel Indemnitee that are not available to such
Evans Stockholder, (ii) such Evans Stockholder is not capable (by reason of
insufficient financial capacity, bankruptcy, receivership, liquidation,
managerial deadlock, managerial neglect or similar events) of maintaining a
reasonable defense of such action or proceeding, or (iii) the action or
proceeding seeks injunctive or other equitable relief against such UbiquiTel
Indemnitee. In the event that a UbiquiTel Indemnitee has elected to defend
against an Asserted Liability under clause (i) or (iii) above, Evans
Stockholders shall be entitled to participate in such defense through counsel
selected by them to the extent necessary to mitigate their liability under
this Agreement. In the event the Evans Stockholders elect to conduct the
defense, they are entitled to have exclusive control over the defense and
settlement thereof and the UbiquiTel Indemnitees will cooperate and make
available to the Evans Stockholders such assistance and materials as they may
reasonably request, at the Evans Stockholders' expense. Notwithstanding the
foregoing, the Evans Stockholders shall not be entitled to control, but may
participate in, and the UbiquiTel Indemnitees shall be entitled to have sole
control over, the defense or settlement of any claim that (i) seeks a
temporary restraining order, preliminary or permanent injunction or specific
performance against the UbiquiTel Indemnitees, or (ii) would impose liability
on the part of the UbiquiTel Indemnitees for which the UbiquiTel Indemnitees
are not entitled to indemnification hereunder. If the Evans Stockholders fail
promptly to defend, contest, or otherwise protect in a timely manner against
any such Asserted Liability, the UbiquiTel Indemnitee shall have the right,
but not the obligation, to defend, contest, or otherwise protect against the
same.

                  (b)      DEFENSE COSTS. If any Evans Stockholder defends an
Asserted Liability in accordance with Section 5(a), it shall do so at its own
expense and shall be responsible for the costs of defense, investigative
costs, attorneys' fees or other expenses incurred to defend the Asserted
Liability (collectively, the "Defense Costs"). If the UbiquiTel Indemnitees
assume the defense of an Asserted Liability by reason of clauses (i), (ii) or
(iii) of subsection (a) above, or because the Evans Stockholders fail to
assume the defense, then such Evans Stockholders shall indemnify the UbiquiTel
Indemnitees for their Defense Costs; PROVIDED, HOWEVER, the Evans Stockholders
shall not be liable for the costs of more than one counsel for all UbiquiTel
Indemnitees in any one jurisdiction.

                  (c)      SETTLEMENT. An Evans Stockholder may settle any
Asserted Liability (i) without the consent of the Ubiquitel Indemnittees, if
such settlement requires only the payment of money and provides a complete
release for the UbiquiTel Indemnitees, or (ii) the UbiquiTel Indemnitees
consent to the settlement. At the request of an Evans Stockholder, a UbiquiTel
Indemnitee shall join in any settlement that complies with this Section 5(c)
to the extent necessary to conclude it.

                                     -3-

<PAGE>

                  (d)      COOPERATION; ACCESS TO BOOKS AND RECORDS. A
UbiquiTel Indemnittee asserting a right to indemnification under this
Agreement shall cooperate in and with the Evans Stockholders in the defense of
an Asserted Liability to the extent such cooperation is reasonably necessary;
provided, however, that the Evans Stockholders shall reimburse the UbiquiTel
Indemnitee for its reasonable out-of-pocket expenses. After the Closing Date,
the Evans Stockholders shall retain custody of the books and records of Evans
(the "Records"), in safekeeping, for the joint benefit of the parties. The
Evans Stockholders shall advise UbiquiTel of the location of the Records and
shall make them available to UbiquiTel for inspection or copying, or shall
make available to UbiquiTel copies of such Records that UbiquiTel shall
request.

         6.       DELAYS OR OMISSIONS, ETC. Except as provided in Section 5(a)
(NOTICE AND OPPORTUNITY TO DEFEND), no delay or omission to exercise any
right, power or remedy inuring to any party under this Agreement shall impair
any such right, power or remedy of such party nor shall it be construed to be
a waiver of any such breach or default, or an acquiescence therein, or of or
in any similar breach or default thereafter occurring; nor shall any waiver of
any single breach or default be deemed a waiver of any other breach or default
theretofore or thereafter occurring.

         7.       GOVERNING LAW. This Agreement shall be governed by, and
construed, interpreted and applied in accordance with the internal laws of the
State of New York. Each party hereto hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts in the state of New
York, or if the courts of such state are not available, then to the exclusive
jurisdiction of the state and federal courts of Pennsylvania, for the purposes
of any action brought to enforce a right of indemnification under this
Agreement. To the extent permitted by applicable law, each party hereby waives
and agrees not to assert, by way of motion, as a defense or otherwise in any
such action, any claim (i) that it is not subject to the jurisdiction of the
above-named courts, (ii) that the action is brought in an inconvenient forum,
(iii) that it is immune from any legal process with respect to itself or its
property, (iv) that the venue of the suit, action or proceeding is improper or
(v) that this Agreement, or the subject matter hereof or thereof, may not be
enforced in or by such courts.

         8.       MISCELLANEOUS.

                  8.1      SUCCESSORS AND ASSIGNS. The provisions hereof shall
inure to the benefit of, and be binding upon, the permitted assigns,
successors, heirs, executors and administrators of the parties hereto. This
Agreement may not be assigned without the written consent of UbiquiTel Parent
and the Evans Stockholders and any attempted assignment without such consent
shall be null and void; PROVIDED, HOWEVER, UbiquiTel Parent, UbiquiTel and the
Merger Subs may assign any of its rights and obligations hereunder to any
Affiliate that agrees in writing to be bound hereby.

                  8.2      AMENDMENT. The parties hereto may modify or amend
this Agreement by written agreement executed and delivered by duly authorized
officers of the respective parties. This Agreement may not be modified or
amended except by written agreement executed and delivered by each of the
respective parties.

                  8.3      NOTICES, ETC. All notices and other communications
required or permitted hereunder shall be in writing and shall be sent by
certified or registered mail, postage prepaid with return receipt requested,
telecopy (with hard copy delivered by overnight courier service), or delivered
by hand, messenger or overnight courier service, and shall be deemed given
when received at the addresses or telecopy numbers of the parties set forth in
the Merger Agreement or at such other address or telecopy number furnished in
the manner provided in the Merger Agreement.

                  8.4      THIRD PARTY BENEFICIARY, ETC. There shall be no
third party beneficiary hereof. Neither the availability of, nor any limit on,
any remedy hereunder limits the remedies of any party hereto against third
parties.

                  8.5      REFORMATION; SEVERABILITY. In case any provision
hereof shall be invalid, illegal or unenforceable, such provision shall be
reformed to best effectuate the intent of the parties and permit enforcement
hereof, and the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby. If such
provision is not capable of reformation, it shall be severed from this
Agreement and enforceability of the remaining provisions shall not in any way
be affected or impaired thereby.

                  8.6      COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one and the same instrument.

                  8.7      TITLES AND SUBTITLES. The titles of the paragraphs
and subparagraphs hereof are for convenience of reference only and are not to
be considered in construing this Agreement.

                  8.8      ENTIRE AGREEMENT. This Agreement (including the
exhibits hereto), the Merger Agreement and Related Agreements, and the other
documents delivered pursuant hereto and thereto and referenced herein and
therein, constitute the full and entire understanding and agreement between
the parties with respect to the subject matters set forth herein and therein
and supersede any other agreements, written or oral, with regard to the
subject matter hereof.
