                              CONSENT AND AGREEMENT
                          (Nortel / Alamosa Wisconsin)

         This Consent and Agreement (this "Consent and Agreement") is entered

partnership ("Sprint Spectrum"), SPRINT COMMUNICATIONS COMPANY, L.P., a Delaware
limited partnership ("Sprint Communications"), WIRELESSCO, L.P., a Delaware
limited partnership ("WirelessCo" and together with Sprint Spectrum and Sprint
Communications, the "Sprint Parties"), and NORTEL NETWORKS INC., a Delaware

accordance with the Credit Agreement hereinafter described, the "Administrative
Agent") for the lenders under that certain Credit Agreement among ALAMOSA PCS,
INC., a Delaware corporation ("Borrower"), the Administrative Agent and the
lenders from time to time party thereto (the "Lenders").

         Alamosa Wisconsin Limited Partnership, a Wisconsin limited partnership
that is a subsidiary of Borrower ("Affiliate"), and the Sprint Parties entered
into a Sprint PCS Management Agreement dated December 6, 1999 (as it may be
amended, modified, or supplemented from time to time, the "Management
Agreement") with Sprint Spectrum providing for the design, construction and
management of the Service Area Network. Affiliate has also entered into the
Sprint PCS Services Agreement (the "Services Agreement") and the Sprint
Trademark and Service Mark License Agreement and the Sprint Spectrum Trademark
and Service Mark License Agreement (together, the "License Agreements") (the
Management Agreement, the Services Agreement and the License Agreements and all
other agreements between Affiliate, Borrower, or their respective subsidiaries,
on the one hand, and any one or more of the Sprint Parties or any subsidiary of
Sprint Corporation on the other hand (whether entered into prior to, on, or
after the date hereof) that relate to the Service Area Network as they may be
amended, modified, or supplemented from time to time, collectively, the "Sprint
Agreements").

         Borrower and certain of its affiliated entities have entered into or
concurrently herewith are entering into that certain Amended and Restated Credit
Agreement dated as of February 8, 2000, with the Administrative Agent and the
Lenders (such Credit Agreement, as it may be amended, supplemented, restated,

provide financing for a portion of the costs of the design and construction of
the Service Area Network and for certain other purposes. The Credit Agreement
and each note, security agreement, pledge agreement, guaranty and any and all
other agreements, documents or instruments entered into in connection with any
of the foregoing, as the same may from time to time be amended, supplemented,
restated, replaced or otherwise modified from time to time, shall collectively
be referred to as the "Loan Documents."

         The Obligations under the Loan Documents are guaranteed by Alamosa PCS
Holdings, Inc., the sole shareholder of Borrower, Affiliate and the other
affiliates of Borrower (collectively, the "Guarantors") pursuant to those
certain Guaranty Agreements executed by the Guarantors in favor of the
Administrative Agent (the "Guaranty Documents").

         As a condition to the availability of credit to Borrower under the
Credit Agreement, the Administrative Agent and the Lenders have required the
execution and delivery of this Consent and


<PAGE>   2


Agreement by the Sprint Parties and have required that Borrower, Affiliate and
the other Guarantors acknowledge, consent and agree to all terms and provisions
of this Consent and Agreement.

         One or more of the Sprint Parties hold, directly or indirectly, the
licenses for the service areas managed by Affiliate as contemplated in the
Management Agreement. As used in this Consent and Agreement, the term "Sprint
PCS" shall refer in each particular instance or application to the Sprint Party
that owns the License in that portion of the Service Area to which the subject
of the instance or application applies.

         All capitalized terms in this Consent and Agreement shall have the same
meanings ascribed to them in the Management Agreement unless otherwise provided
in this Consent and Agreement; provided, that the terms "Commitments",
"Default", "Event of Default", "Loan Documents" and "Obligations" shall have the
meanings ascribed to them in the Credit Agreement.

         Accordingly, each Sprint Party and the Administrative Agent, on behalf
of itself and for the Lenders, hereby agree as follows:

         SECTION 1. Consent to Security Interest. In connection with the
transactions contemplated by the Credit Agreement and the other Loan Documents,
(a) Borrower has granted or will grant to the Administrative Agent, for the
benefit of the Lenders, a first priority security interest in and lien upon
substantially all of its assets and property, tangible and intangible, whether
now owned or hereafter acquired or arising, and all proceeds and products
thereof and accessions thereto, and a first priority security interest in and
pledge of all partnership interests, membership interests or other equity
interests in Affiliate (the "Pledged Equity"), and (b) Affiliate has granted or
will grant to the Administrative Agent, for the benefit of the Lenders, a first
priority security interest in and lien upon substantially all of its assets and
property, tangible and intangible, whether now owned or hereafter acquired or
arising, and all proceeds and products thereof and accessions thereto, including
but not limited to the Operating Assets, and a first priority security interest
and lien upon the rights of Affiliate in, to and under the Sprint Agreements.
The foregoing security interests, liens and pledges are referred to collectively
as the "Security Interests" and the foregoing assets and property in which the
Administrative Agent, for the benefit of the Lenders, has been or will be
granted a first priority security interest in and lien are referred to
collectively as the "Collateral". In addition to the foregoing, each of the
other affiliated entities of Borrower and Affiliate have granted or will grant
to the Administrative Agent, for the benefit of the Lenders, a first priority
security interest in and lien upon substantially all of its assets and property,
tangible and intangible, whether now owned or hereafter acquired or arising, and
all proceeds and products thereof and accessions thereto, which security
interests and liens are referred to collectively as the "Additional Security
Interests" and which assets and property are referred to collectively as the
"Additional Collateral." Each Sprint Party (i) acknowledges notice of the Credit
Agreement and the other Loan Documents, (ii) consents to the granting of the
Security Interests in the Collateral and of the Additional Security Interests in
the Additional Collateral to the Administrative Agent, for the benefit of the
Lenders, and (iii) agrees that (a) neither it nor any subsidiary of Sprint
Corporation will challenge or contest that the Security Interests and the
Additional Security Interests are valid, enforceable and duly perfected first
priority security interests and liens in and to the Collateral and the
Additional Collateral, (b) neither it nor any subsidiary of Sprint Corporation
will argue that any such Security Interest or Additional Security Interest is
subject to avoidance, limitation or subordination under any legal or equitable
theory or cause of action, and (c) so long as the


                                       2


<PAGE>   3


Management Agreement is in effect, it will not sell, transfer or assign all or
part of the Licenses that Affiliate has the right to use; provided, however,
that notwithstanding the foregoing, a Sprint Party may at any time sell,
transfer or assign all or part of the Licenses that Affiliate has the right to
use in accordance with a transaction allowed under Section 17.15.5 of the
Management Agreement, so long as the buyer, transferee or assignee, as the case
may be, agrees to be bound by the terms of this Consent and Agreement as such
terms relate to such Licenses.

         Each Sprint Party acknowledges and agrees that (i) Sections 17.15.1 and
17.15.2 of the Management Agreement do not apply to the assignment of
Affiliate's rights under the Sprint Agreements to the Administrative Agent or
the Lenders under the Loan Documents or in connection with a transaction
permitted pursuant to this Consent and Agreement to any other Person pursuant to
the Loan Documents or to any other assignment in connection with any transaction
permitted pursuant to this Consent and Agreement and (ii) Section 17.15.3 of the
Management Agreement shall not apply to any Change of Control of Affiliate in
connection with the exercise by the Administrative Agent of any of its rights or
remedies under the Loan Documents, including without limitation in connection
with the sale of the partnership, membership or shareholder interests of
Affiliate to any Person or to any other Change of Control of Affiliate;
provided, however, Section 17.15.3 of the Management Agreement shall apply to
any such transaction if such transaction is not with the Administrative Agent or
the Lenders or is not a transaction permitted pursuant to this Consent and
Agreement. It is understood that any assignment described in this Section 1 to
the Administrative Agent or the Lenders is hereby consented to by the Sprint
Parties; provided, that any subsequent assignment by the Administrative Agent or
the Lenders shall be in accordance with the terms of this Consent and Agreement.

         SECTION 2. Payments. Upon receipt of the Administrative Agent's written
instructions, each Sprint Party agrees to make all payments (if any) to be made
by it under the Sprint Agreements, subject to its rights of setoff or recoupment
with respect to such payments as permitted under Section 10.6 of the Management
Agreement, to Affiliate directly to the Administrative Agent, or otherwise as
the Administrative Agent shall direct; provided, that during the period that
Sprint PCS is making such payments directly to the Administrative Agent or its
designee pursuant to this Section 2, Sprint PCS' setoff and recoupment rights
under such Section 10.6 shall not be limited to undisputed amounts. The
Administrative Agent hereby agrees that the Administrative Agent will not give
any such written instructions for it to receive such payments directly from a
Sprint Party unless an Event of Default has occurred under the Credit Agreement
and is continuing. Such written instructions to make payments directly to the
Administrative Agent shall be effective only so long as an Event of Default is
continuing, and the Administrative Agent will revoke such instructions promptly
following the cure of such Event of Default. Any payments made by any Sprint
Party directly to, or at the direction of, the Administrative Agent shall fully
satisfy any obligation of such Sprint Party to make payments to Affiliate under
the Sprint Agreements to the extent of such payments.

         SECTION 3. Notice and Effect of Event of Default, Management Agreement
Breach and Event of Termination. The Administrative Agent agrees to provide to
Sprint PCS a copy of any written notice that Administrative Agent sends to
Borrower, promptly after sending such notice, that a Default or an Event of
Default has occurred and is continuing, and Sprint PCS agrees to provide to the
Administrative Agent a copy of any written notice that Sprint PCS sends to
Affiliate, promptly after sending such notice, that an Event of Termination or
an event that if not cured, or if notice is provided,


                                       3

<PAGE>   4


will constitute an Event of Termination (each of an Event of Termination and an
event that if not cured would constitute an Event of Termination, a "Management
Agreement Breach") has occurred. The Sprint Parties acknowledge that the
Administrative Agent has informed them that an Event of Termination constitutes
an Event of Default under the Loan Documents, and the Sprint Parties further
acknowledge that the Management Agreement does not prohibit Affiliate from
curing such an Event of Default.

         SECTION 4. Event of Default without a Management Agreement Breach.

                  (a) Affiliate Remains as Manager or Interim Manager Appointed.
         Upon and during the continuation of an Event of Default when no
         Management Agreement Breach as to which Sprint PCS has given the
         Administrative Agent notice exists on the original date of occurrence
         of such Event of Default, the Administrative Agent may, by prior
         written notice to Sprint PCS, (i) allow Affiliate to continue to act
         as the Manager under the Sprint Agreements, (ii) appoint Sprint
         Spectrum to act as "Interim Manager" under the Sprint Agreements, or
         (iii) appoint a Person other than Sprint Spectrum to act as Interim
         Manager under the Sprint Agreements. If the Administrative Agent
         initially allows Affiliate to continue to act as the Manager under the
         Sprint Agreements, the Administrative Agent may later, during a
         continuation of an Event of Default, remove the Affiliate as Manager
         and take the action described above in clauses (ii) and (iii). The
         date on which a Person begins serving as Interim Manager shall be the
         "Commencement Date."

                  (b) Sprint Spectrum or Sprint Spectrum Designee as Interim
         Manager. If the Administrative Agent appoints Sprint Spectrum as
         Interim Manager, within 14 days after its appointment Sprint Spectrum
         shall accept the position or designate another Person (a "Sprint
         Spectrum Designee") to act as Interim Manager under the Sprint
         Agreements. The Administrative Agent shall accept Sprint Spectrum and
         any Sprint Spectrum Designee that is then acting as an Other Manager
         (other than Affiliate) to act as Interim Manager under the Sprint
         Agreements. Any Sprint Spectrum Designee that is not an Other Manager
         must be acceptable to the Administrative Agent, which acceptance will
         not be unreasonably withheld. If, within 30 days after the
         Administrative Agent gives Sprint Spectrum notice of its appointment as
         Interim Manager, Sprint Spectrum or a Sprint Spectrum Designee does not
         agree to act as Interim Manager, then the Administrative Agent shall
         have the right to appoint an Administrative Agent Designee as Interim
         Manager in accordance with Section 4(c). At the discretion of the
         Administrative Agent, Sprint Spectrum or the Sprint Spectrum Designee
         shall serve as Interim Manager for up to six months from the
         Commencement Date.

                  Upon the expiration of its initial six-month period as Interim
         Manager under the Sprint Agreements, Sprint Spectrum or the Sprint
         Spectrum Designee will agree, at the written request of the
         Administrative Agent, to serve as Interim Manager for up to six months
         from such expiration date until the Administrative Agent gives Sprint
         Spectrum or the Sprint Spectrum Designee at least 30 days' written
         notice of its desire to terminate the relationship; provided, that the
         extended period will be for 12 months rather than six months (for a
         complete term of 18 months) in the event, as of the date of the initial
         appointment, the aggregate number of pops that Affiliate and all Other
         Managers have the right to serve under their respective management
         agreements with the Sprint Parties is less than 40 million (such six or
         12 month period, the

                                       4

<PAGE>   5

         "Extension Period"). If Sprint Spectrum's or the Sprint Spectrum
         Designee's term as Interim Manager is so extended at the request of
         the Administrative Agent, then the Administrative Agent agrees that
         Sprint Spectrum's or the Sprint Spectrum Designee's right to be
         reimbursed by the Affiliate promptly for all amounts previously
         expended by Sprint Spectrum or the Sprint Spectrum Designee under
         Section 11.6.3 of the Management Agreement (which expenditures were
         incurred in accordance with Section 9 of this Consent and Agreement)
         shall no longer be subordinated to the Obligations as provided in
         Section 9 in this Consent and Agreement, and Sprint Spectrum's or the
         Sprint Spectrum Designee's right to be reimbursed by Affiliate for any
         expenses it incurs pursuant to its rights under Section 11.6.3 of the
         Management Agreement as provided in the Management Agreement (which
         expenditures were incurred in accordance with Section 9 of this
         Consent and Agreement) shall not be subject to the subordination to
         the Obligations as provided in Section 9 of this Consent and
         Agreement; provided, that Sprint Spectrum or the Sprint Spectrum
         Designee's right to be reimbursed for amounts expended under Section
         11.6.3 of the Management Agreement that exceed in an aggregate
         amount 5% of Affiliate's partner's, shareholder's or member's equity or
         capital account plus Affiliate's long-term debt (i.e., notes that on
         their face are scheduled to mature more than one year from the date
         issued), as reflected on Affiliate's books (the "Reimbursement Limit")
         shall remain subordinated to the Obligations as provided in Section 9
         of this Consent and Agreement. Notwithstanding any other provision in
         this Section 4(b) to the contrary, Sprint Spectrum or the Sprint
         Spectrum Designee shall not be required to continue to serve as Interim
         Manager during the Extension Period at any time after 30 days following
         delivery by it to the Administrative Agent of written notice that
         Sprint Spectrum or the Sprint Spectrum Designee needs to expend amounts
         under Section 11.6.3 of the Management Agreement that Sprint Spectrum
         or the Sprint Spectrum Designee reasonably believes will not be
         reimbursed based on the projected Collected Revenues for the remainder
         of the Extension Period or reimbursed by the Lenders. If it becomes
         necessary for Sprint Spectrum or the Sprint Spectrum Designee to expend
         any amount that it believes will not be reimbursed or that exceeds the
         Reimbursement Limit, Sprint Spectrum or the Sprint Spectrum Designee is
         not required to incur such expense.

                  Upon the termination or expiration of the term of Sprint
         Spectrum or the Sprint Spectrum Designee as Interim Manager, the
         Administrative Agent shall have the right to appoint a successor
         Interim Manager in accordance with Section 4(c).

                  (c) Administrative Agent Designee as Interim Manager. If the
         Administrative Agent elects to appoint a Person other than Sprint
         Spectrum to act as Interim Manager under the Sprint Agreements (an
         "Administrative Agent Designee") as permitted under Sections 4(a)(iii)
         and 4(b), such Administrative Agent Designee must (i) agree to serve as
         Interim Manager for six months unless terminated earlier by Sprint PCS
         because of a material breach by the Administrative Agent Designee of
         the terms of the Sprint Agreements that is not timely cured or by the
         Administrative Agent in its discretion, (ii) meet the applicable
         "Successor Manager Requirements" set forth below in Section 13, and
         (iii) agree to comply with the terms of the Sprint Agreements but will
         not be required to assume the existing liabilities of Affiliate. In the
         case of a proposed Administrative Agent Designee, Sprint PCS shall
         provide to the Administrative Agent, within 10 Business Days after the
         request therefor, a detailed description of all information reasonably
         requested by Sprint PCS to enable Sprint PCS to determine if a


                                       5

<PAGE>   6


         proposed Administrative Agent Designee satisfies the Successor Manager
         Requirements. Sprint PCS agrees to inform Administrative Agent within
         20 days after it receives such information respecting such proposed
         Administrative Agent Designee from the Administrative Agent whether
         such designee satisfies the Successor Manager Requirements. If Sprint
         PCS does not so inform the Administrative Agent within such 20-day
         period, then Sprint PCS shall be deemed to agree, for all purposes of
         this Consent and Agreement, that such proposed designee satisfies the
         Successor Manager Requirements. A Person that satisfies the Successor
         Manager Requirements (or is deemed to satisfy such requirements)
         qualifies under the Management Agreement to become a Successor
         Manager, unless the Administrative Agent Designee materially breaches
         the terms of a Sprint Agreement while acting as Interim Manager or no
         longer meets the Successor Manager Requirements. The Administrative
         Agent Designee may continue to serve as Interim Manager after the
         initial six-month period at the Administrative Agent's discretion, so
         long as the Administrative Agent Designee continues to satisfy the
         Successor Manager Requirements and it does not materially breach the
         terms of the Sprint Agreements. If the Administrative Agent Designee
         materially breaches any Sprint Agreement while acting as Interim
         Manager, then Sprint PCS and the Administrative Agent have the rights
         set forth in Section 5; provided, that Sprint PCS may not allow
         Affiliate to act as the Manager of the Sprint Agreements without the
         Administrative Agent's consent.

         SECTION 5. Event of Default Created by a Management Agreement Breach.

                  (a) Affiliate Remains as Manager or Interim Manager Appointed.
         Upon an Event of Default created by a Management Agreement Breach (so
         long as at such time an Event of Default not created by a Management
         Agreement Breach as to which Administrative Agent has given Sprint PCS
         notice is not in existence), Sprint PCS may by prior written notice to
         Administrative Agent (i) allow Affiliate to continue to act as the
         Manager under the Sprint Agreements if approved by the Administrative
         Agent, (ii) act as Interim Manager under the Sprint Agreements (in the
         case of Sprint Spectrum) or appoint Sprint Spectrum as Interim Manager
         (in the case of SprintCom), or (iii) appoint a Sprint Spectrum Designee
         to act as Interim Manager under the Sprint Agreements as provided in
         paragraph (b) below. If Sprint PCS initially allows Affiliate to
         continue to act as the Manager under the Sprint Agreements, Sprint PCS
         may later remove the Affiliate as Manager and take the action described
         above in clauses (ii) and (iii). The Administrative Agent shall have no
         right to appoint an Interim Manager when an Event of Default is caused
         by a Management Agreement Breach (unless an Event of Default not
         created by a Management Agreement Breach is in existence), unless
         Sprint PCS elects not to act as Interim Manager or to appoint a Sprint
         Spectrum Designee.

                  (b) Sprint Spectrum or Sprint Spectrum Designee as Interim
         Manager. If Sprint Spectrum acts as Interim Manager or designates a
         Sprint Spectrum Designee to act as Interim Manager under the Sprint
         Agreements, the Interim Manager shall serve as Interim Manager for up
         to six months from the Commencement Date, at the discretion of Sprint
         Spectrum. The Administrative Agent shall accept Sprint Spectrum and any
         Sprint Spectrum Designee that is then acting as an Other Manager (other
         than Affiliate) to act as Interim Manager under the Sprint Agreements.
         Any Sprint Spectrum Designee that is not then acting as an Other
         Manager must be acceptable to the Administrative Agent, which
         acceptance will not be unreasonably withheld.

                                       6

<PAGE>   7

                  Upon the expiration of its initial six-month period as Interim
         Manager under the Sprint Agreements, Sprint Spectrum or the Sprint
         Spectrum Designee will agree to serve as Interim Manager for the
         Extension Period until the Administrative Agent gives Sprint Spectrum
         or the Sprint Spectrum Designee at least 30 days' written notice of its
         desire to terminate the relationship. If Sprint Spectrum's or the
         Sprint Spectrum Designee's term as Interim Manager is extended, then
         the Administrative Agent agrees that Sprint Spectrum's or the Sprint
         Spectrum Designee's right to be reimbursed by the Affiliate promptly
         for all amounts previously expended by Sprint Spectrum or the Sprint
         Spectrum Designee under Section 11.6.3 of the Management Agreement
         (which expenditures were incurred in accordance with Section 9 of this
         Consent and Agreement) shall no longer be subordinated to the
         Obligations as provided in Section 9 of this Consent and Agreement, and
         Sprint Spectrum's or the Sprint Spectrum Designee's right to be
         reimbursed by the Affiliate for any expenses it incurs pursuant to its
         rights under Section 11.6.3 of the Management Agreement as provided in
         the Management Agreement (which expenditures were incurred in
         accordance with Section 9 of this Consent and Agreement) shall not be
         subject to subordination to the Obligations as provided in Section 9 of
         this Consent and Agreement; provided, that Sprint Spectrum's or the
         Sprint Spectrum Designee's right to be reimbursed for amounts expended
         under Section 11.6.3 of the Management Agreement in an aggregate
         amount that exceed the Reimbursement Limit shall remain subordinated
         to the Obligations as provided in Section 9 of this Consent and
         Agreement. Notwithstanding any other provision in this Section 5(b) to
         the contrary, Sprint Spectrum or the Sprint Spectrum Designee shall
         not be required to continue to serve as Interim Manager during the
         Extension Period at any time after 30 days following delivery by it to
         the Administrative Agent of written notice that Sprint Spectrum or the
         Sprint Spectrum Designee needs to expend amounts under Section 11.6.3
         of the Management Agreement that Sprint Spectrum or the Sprint
         Spectrum Designee reasonably believes will not be reimbursed based on
         the projected Collected Revenues for the remainder of the Extension
         Period or reimbursed by the Lenders. If it becomes necessary for
         Sprint Spectrum or the Sprint Spectrum Designee to expend any amount
         that it believes will not be reimbursed or that exceeds the
         Reimbursement Limit, Sprint Spectrum or the Sprint Spectrum Designee
         is not required to incur such expense.

                  Upon the termination or expiration of the term of Sprint
         Spectrum or the Sprint Spectrum Designee as Interim Manager and with
         the consent of the Administrative Agent (which consent shall not be
         unreasonably withheld or delayed), Sprint Spectrum shall have the right
         to appoint a successor Interim Manager in accordance with Section 5(a).

                  (c) Administrative Agent Designee as Interim Manager.
         Notwithstanding anything in paragraph (a) above to the contrary, if,
         after Acceleration (as defined in Section 6(a) of this Consent and
         Agreement) and within 30 days after Sprint PCS gives the Administrative
         Agent notice of a Management Agreement Breach, Sprint Spectrum does not
         agree to act as Interim Manager or does not obtain the consent of a
         Sprint Spectrum Designee to act as Interim Manager under the Sprint
         Agreements, or if Sprint Spectrum or the Sprint Spectrum Designee gives
         the Administrative Agent notice of its resignation as Interim Manager
         and Sprint Spectrum fails to appoint a successor in accordance with
         Section 5(b) within 30 days after such resignation, the Administrative
         Agent may appoint an Administrative Agent Designee to act


                                       7

         as Interim Manager. Such Administrative Agent Designee must (i) agree
         to serve as Interim Manager for six months unless terminated earlier
         by Sprint PCS because of a material breach by the Administrative Agent
         Designee of the terms of the Sprint Agreements or by the
         Administrative Agent in its discretion, (ii) meet the applicable
         Successor Manager Requirements, and (iii) agree to comply with the
         terms of the Sprint Agreements. In the case of a proposed
         Administrative Agent Designee, Sprint PCS shall provide to the
         Administrative Agent, within 10 Business Days after the request
         therefor, a detailed description of all information reasonably
         requested by Sprint PCS to enable Sprint PCS to determine if a
         proposed Administrative Agent Designee satisfies the Successor Manager
         Requirements. Sprint PCS agrees to inform Administrative Agent within
         20 days after it receives such information respecting such proposed
         Administrative Agent Designee from the Administrative Agent whether
         such designee satisfies the Successor Manager Requirements. If Sprint
         PCS does not so inform the Administrative Agent within such 20-day
         period, then Sprint PCS shall be deemed to agree, for all purposes of
         this Consent and Agreement, that such proposed designee satisfies the
         Successor Manager Requirements. A Person that satisfies the Successor
         Manager Requirements qualifies under the Management Agreement to
         become a Successor Manager, unless the Administrative Agent Designee
         materially breaches the terms of a Sprint Agreement while acting as
         Interim Manager or no longer meets the Successor Manager Requirements.
         The Administrative Agent Designee may continue to serve as Interim
         Manager after the initial six-month period at the Administrative
         Agent's discretion, so long as the Administrative Agent Designee
         continues to satisfy the Successor Manager Requirements and it does
         not materially breach the terms of the Sprint Agreements. If the
         Administrative Agent Designee materially breaches any Sprint Agreement
         while acting as Interim Manager, then Sprint PCS and the
         Administrative Agent have the rights set forth in Section 5; provided,
         that Sprint PCS may not allow Affiliate to act as the Manager of the
         Sprint Agreements without the Administrative Agent's consent.

         SECTION 6. Purchase and Sale of the Operating Assets.  Upon the
occurrence and during the continuation of an Event of Default, the following
provisions shall govern the purchase and sale of the Operating Assets:

                  (a) Acceleration of the Obligations Under the Loan Documents.
         In the event the Lenders accelerate the maturity of the Obligations
         under the Loan Documents (an "Acceleration" and, the date thereof, an
         "Acceleration Date"), the Administrative Agent shall give written
         notice thereof to Sprint PCS. Upon receipt of notice of Acceleration,
         Sprint PCS shall have the right, to which right Borrower and Affiliate,
         by acknowledging this Consent and Agreement, expressly agree, to
         purchase the Operating Assets from Borrower and Affiliate for an amount
         equal to the greater of (i) 72% of the Entire Business Value (as
         defined in the Management Agreement), valued in accordance with the
         procedure set forth in Section 11.7 of the Management Agreement (with
         the assumption that the deemed ownership of the Disaggregated License
         under Section 11.7.3 of the Management Agreement includes the transfer
         of the Sprint PCS customers as contemplated by Section 11.4 of the
         Management Agreement), and (ii) the aggregate amount of the
         Obligations. Sprint PCS shall, within 60 days of receipt of notice of
         Acceleration, give Borrower, Affiliate and the Administrative Agent
         notice of its intent to exercise the purchase right. In the event
         Sprint PCS gives the Administrative Agent written notice of its intent
         to purchase the Operating Assets, the


                                       8

<PAGE>   9

         Administrative Agent agrees that it shall not enforce its Security
         Interests in the Collateral until the earlier to occur of (i)
         expiration of the period consisting of 120 days after the Acceleration
         Date (or such later date that shall be provided for in the purchase
         agreement and acceptable to the Administrative Agent in its discretion
         to close the purchase of the Operating Assets) or (ii) receipt by
         Administrative Agent, Borrower and Affiliate from Sprint PCS of
         written notice that Sprint PCS has determined not to proceed with the
         closing of the purchase of the Operating Assets for any reason. If
         after the 120-day period after the Acceleration Date, Borrower or
         Affiliate receives any purchase offer for the Operating Assets or the
         Pledged Equity that is confirmed in writing by Borrower or Affiliate
         to be acceptable to Borrower or Affiliate, Sprint PCS shall have the
         right, subject to the consent of the Administrative Agent, to purchase
         the Operating Assets or the Pledged Equity, as the case may be, on
         terms and conditions at least as favorable to Borrower and Affiliate
         as the terms and conditions proposed in such offer so long as within
         14 Business Days after Sprint PCS's receipt of such other offer Sprint
         PCS offers to purchase the Operating Assets or the Pledged Equity and
         so long as the conditions of Sprint PCS's offer and the amount of time
         it will take Sprint PCS to effect such purchase is acceptable to
         Borrower, Affiliate and Administrative Agent. Any such offer shall be
         confirmed in writing by the third party offeror. In the event Sprint
         PCS exercises its rights under this Section 6(a), (i) Borrower and
         Affiliate shall sell the Operating Assets or the Pledged Equity to
         Sprint PCS, (ii) the Administrative Agent and the Lenders shall
         consent to such purchase and sale provided that the proceeds thereof
         shall be sufficient to repay the aggregate amount of the Obligations,
         and (iii) Sprint PCS shall make all payments to be made under this
         Section 6(a) to Administrative Agent for its application against the
         Obligations and any additional amounts shall be paid to Borrower or
         Affiliate or other owner of the assets sold unless otherwise required
         by law or by this Consent and Agreement. The purchase right of the
         Sprint Parties under this Section 6(a) shall be in substitution of the
         purchase rights of the Sprint Parties under Section 11.6.1 of the
         Management Agreement. If Sprint PCS purchases the Operating Assets or
         the Pledged Equity as permitted under this Section 6(a), the
         Administrative Agent and the Guarantors will release or assign their
         interests in the Collateral, the Additional Collateral and the
         Guaranty Documents as described below in Section 6(e) upon payment in
         full of the aggregate amount of the Obligations and the termination of
         all Commitments to advance credit under the Credit Agreement.

                  (b) Sale of Operating Assets to Third Parties. If the Sprint
         Parties do not purchase the Operating Assets after an Acceleration as
         described above in Section 6(a), the Collateral may be sold as follows:

                           (i) Sale to Successor Manager. The Collateral may be
         sold by the Administrative Agent (in its sole discretion) in the
         exercise of certain of its rights and remedies as a secured party under
         the Loan Documents or by Borrower or Affiliate, at the discretion of
         the Administrative Agent, to a person that satisfies the Successor
         Manager Requirements. Sprint PCS shall provide to the Administrative
         Agent, with a copy to Borrower, within 10 Business Days after the
         request therefor, a detailed description of all information reasonably
         requested by Sprint PCS to enable Sprint PCS to determine if a proposed
         buyer satisfies the Successor Manager


                                       9

<PAGE>   10

         Requirements. Sprint PCS agrees to inform the Administrative Agent and
         Borrower within 20 days after it receives such information respecting
         such proposed buyer from the Administrative Agent whether such
         designee satisfies the Successor Manager Requirements. If Sprint PCS
         does not so inform the Administrative Agent within such 20-day period,
         then Sprint PCS shall be deemed to agree, for all purposes of this
         Consent and Agreement, that such proposed designee satisfies the
         Successor Manager Requirements. If the proposed buyer satisfies the
         Successor Manager Requirements (or is deemed to satisfy such
         requirements) and wishes to become a "Successor Manager", the buyer
         must agree to be bound by the Sprint Agreements; provided, that buyer
         shall have no responsibility or liability for any liability to any
         Person other than a Sprint Party and Related Party of Sprint PCS
         arising out of Affiliate's operations prior to the date buyer becomes
         bound by the Sprint Agreements. In such case the Sprint Agreements
         shall remain in full force and effect with the buyer as Successor
         Manager and this Consent and Agreement shall remain in full force and
         effect for the benefit of the Successor Manager and any Person
         providing senior secured debt financing to such Successor Manager if
         required by such Person. Sprint PCS agrees, with respect to any past
         failure of Affiliate to perform any obligation under the Sprint
         Agreements, that the Successor Manager shall have the same amount of
         time to perform such obligation that Affiliate had under the Sprint
         Agreements, with the performance period commencing on the date on
         which the buyer becomes a Successor Manager. Sprint PCS shall permit
         the performance period set forth in the Management Agreement to be
         extended for such period of time that Sprint PCS believes is
         reasonable to allow Successor Manager to perform such unperformed
         obligations.

                          (ii) Sale to Other than Successor Manager. The
         Collateral may be sold pursuant to the exercise by the Administrative
         Agent or the Lenders of their rights and remedies under the Loan
         Documents or by Borrower or Affiliate, at the discretion of the
         Administrative Agent (subject to requirements of applicable law) to a
         person that does not satisfy the Successor Manager Requirements or to a
         person that does not wish to become a Successor Manager, but only under
         the following conditions:

                                    (A) the Sprint Parties may terminate the
         Sprint Agreements with such buyer following the closing of such
         purchase (and the Administrative Agent and the buyer shall have no
         rights thereto or thereunder with respect to events occurring after
         the closing of such purchase);

                                    (B) the buyer may purchase the Disaggregated
         License as described below in Section 6(b)(iv) and with the
         Disaggregated License having the characteristics described in the
         definition thereof; and

                                    (C) the purchase agreement with the buyer
         contains the requirements set forth in Section 6(c) of this Consent and
         Agreement.

                           (iii) Confidentiality Agreement. Before any potential
         buyer is provided Confidential Information respecting the potential
         purchase of any of the Collateral (which buyer shall be entitled to
         receive), the potential buyer shall execute a confidentiality agreement
         in the form attached as Exhibit A with such changes thereto as may be
         reasonably requested by the parties to the agreement; provided,
         however, in the event the potential buyer does not satisfy the
         Successor Manager Requirements or has notified Borrower, Sprint PCS or
         the Administrative Agent that it does not intend to be a Successor
         Manager, Confidential Information that constitutes or relates to any
         technical, marketing, financial, strategic or other


                                       10


<PAGE>   11

         information concerning any of the Sprint Parties and that does not
         pertain to the business of Affiliate shall not be permitted to be
         provided to such potential buyer.

                           (iv) Sale of Disaggregated Licenses. Sprint PCS will
         sell Disaggregated Licenses as follows when required under Section
         6(b)(ii)(B):

                                    (A) If a buyer wishes to purchase spectrum
         in connection with its purchase of the Operating Assets, it will
         purchase such spectrum from the Affiliate and Sprint PCS as follows.
         The buyer will purchase from the Affiliate or its Related Parties any
         licenses that Affiliate or such Related Parties own (the "Affiliate's
         Licenses"). If the Affiliate's Licenses were not being used to operate
         the Service Area Network, Sprint PCS will reimburse the buyer for the
         microwave relocation costs incurred to clear the spectrum bought from
         the Affiliate or its Related Parties that the buyer will need to use
         to operate the Service Area Network as constructed on the date that
         the buyer purchases the Operating Assets. If the buyer does not meet
         the FCC requirements to buy the Affiliate's Licenses, the buyer will
         seek a waiver from the FCC of the restrictions that prohibit the
         buyer's ownership of such licenses. While any such FCC application is
         pending and while the buyer is clearing the microwave from the
         Affiliate's spectrum, the buyer may continue to use Sprint PCS'
         Spectrum on which the Service Area Network operates. Sprint PCS will
         sell its Disaggregated Licenses as described in Sections 6(b)(iv)(B),
         6(b)(iv)(C) and 6(b)(iv)(D) only in those BTAs in which (1) the
         Affiliate or its Related Parties do not own a license or the
         obligation to sell the license is unenforceable, (2) the FCC will not
         approve the transfer of the Affiliate's License to the buyer, or (3)
         Sprint PCS determines that it does not wish to reimburse the buyer for
         the cost of the microwave relocation.

                                    (B) If the buyer, an entity with respect to
         which such buyer directly or indirectly through one or more persons
         owns the total voting power or at least 50% of the total voting power
         or at least 50% of the total equity (a "controlled entity"), an entity
         that directly or indirectly through one or more persons has a parent
         entity that owns at least 50% of the voting power or at least 50% of
         the total equity of both the buyer and the common controlled entity (a
         "common controlled entity"), owns a license to provide wireless
         service to at least 50% of the pops in a BTA with respect to which
         such buyer proposes to purchase Spectrum (each a "Restricted Party"
         with respect to such BTA), the buyer may buy only 5 MHZ of Spectrum
         from Sprint PCS for such BTA.

                                    (C) If the buyer is not a Restricted Party
         for a BTA with respect to which such buyer proposes to purchase
         Spectrum, and either does not satisfy the Successor Manager
         Requirements (other than those set forth in Section 13(b) of this
         Consent and Agreement) or does not wish to be a Successor Manager,
         then the buyer may buy 5 MHZ, 7.5 MHZ or 10 MHZ of Spectrum from
         Sprint PCS as the buyer determines in its sole discretion.

                                    (D) If Sprint PCS sells a Disaggregated
         License to a buyer as required under this Section 6(b)(iv), the buyer
         must pay a price equal to the sum of (1) the original cost of the
         applicable License to Sprint PCS pro rated on a pops and spectrum
         basis, plus (2) the microwave relocation costs paid by Sprint PCS
         attributable to clearing the Spectrum in the Disaggregated License,
         plus (3) the amount of carrying costs to Sprint PCS attributable


                                       11

<PAGE>   12

         to such original cost and microwave relocation costs from the date of
         this Consent and Agreement to and including the date on which the
         Disaggregated License is transferred to the buyer, based on a rate of
         12 percent per annum.

                  (c) No Direct Solicitation of Customers. Upon the sale of the
         Collateral or the Disaggregated License in accordance with this Consent
         and Agreement pursuant to Section 6(b)(ii), then the Sprint Parties
         agree to transfer to the buyer thereof the customers with a MIN
         assigned to the Service Area covered by the Disaggregated License, but
         Sprint PCS shall retain the customers of a national account and any
         resellers who are then party to a resale agreement with Sprint PCS.
         Each Sprint Party agrees to take all actions reasonably requested by
         the buyer of the Collateral to fully transfer to such purchaser such
         customers. Each Sprint Party agrees that neither it nor any of its
         Related Parties will directly or indirectly solicit, for six months
         after the date of transfer, the customers with a MIN assigned to the
         Service Area covered by the Disaggregated License; provided, that
         Sprint PCS retains the customers of a national account and any
         resellers that have entered into a resale agreement with Sprint PCS,
         Sprint PCS may advertise nationally, regionally and locally, and engage
         direct marketing firms to solicit customers generally. If the buyer
         continues to operate the purchased assets as a wireless network in the
         same geographic area on a network that is technologically compatible
         with Sprint PCS's network, the buyer and Sprint PCS shall each agree to
         provide roaming services to the other (in the case of Sprint PCS, the
         roaming services shall be provided to those customers of buyer in the
         geographic area serviced by the Disaggregated License roaming
         nationally and, in the case of buyer, the roaming services shall be
         provided to those customers of Sprint PCS roaming in the geographic
         area covered by the Disaggregated License) pursuant to a roaming
         agreement to be entered into between buyer and Sprint PCS and to be
         mutually agreed upon so long as such agreement is based on Sprint PCS's
         then standard roaming agreement used by Sprint PCS in the industry and
         the price that each party shall pay the other party for roaming
         services provided to the first party shall be a price equal to the
         lesser of: (1) MFN Pricing provided by buyer to third parties roaming
         in the geographic area serviced by the Disaggregated License; and (2)
         the national average paid by Sprint PCS to third parties for Sprint
         PCS's customers to roam in such third parties' geographic areas
         (including Other Managers). Such obligations with respect to roaming
         shall continue until such roaming agreement is terminated pursuant to
         its terms. The buyer shall agree in writing that if it continues to
         operate the purchased assets as a wireless network in the same
         geographic area on a network that is technologically compatible with
         Sprint PCS's network, the buyer shall, to the extent required by law,
         provide resale to Sprint PCS in the geographic area covered by the
         Disaggregated License at the MFN Pricing that buyer charges third
         parties who purchase resale from buyer; provided, however, if buyer is
         not offering resale to any other customers then pricing of resale
         provided to Sprint PCS shall be as mutually agreed; and provided,
         further, however, whether or not buyer is required by law to offer
         such resale, buyer shall offer such resale (on the terms described in
         this sentence) to national customers of Sprint PCS.

                  (d) Deferral of Portion of Collected Revenues. (i) Under
         Section 10.1.1 of the Management Agreement, Sprint PCS retains 8% of
         the Collected Revenues on a weekly basis (the "Retained Amount").
         Following an Acceleration and for up to two years after such
         Acceleration, Sprint PCS shall retain only one half of the Retained
         Amount, and the remaining one half of the Retained Amount shall be
         advanced to Affiliate (or, if so directed by the


                                       12


<PAGE>   13

         Administrative Agent pursuant to Section 2 hereof, to the
         Administrative Agent) at the time the weekly fee provided under
         Section 10.1.1 of the Management Agreement is paid; provided, that
         after the first anniversary of the Acceleration Date, Sprint PCS shall
         retain the entire Retained Amount if Sprint PCS is not serving as the
         Interim Manager.

                           (ii) The portion of the Retained Amount advanced to
         Affiliate (or, if so directed by the Administrative Agent pursuant to
         Section 2 hereof, to the Administrative Agent) (the "Deferred Amount")
         shall be evidenced by a promissory note executed by Affiliate
         contemporaneously with this Consent and Agreement in the form of
         Exhibit B hereto (the "Deferred Amount Note").

                           (A) Amounts will be drawn on the Deferred Amount Note
                  each time Sprint PCS advances a Deferred Amount to Affiliate
                  or the Administrative Agent.


                           (B) The Deferred Amount Note will bear interest at a
                  rate equal to the greatest of (I) the average interest rate of
                  Affiliate's secured debt, (II) the average rate of Affiliate's
                  unsecured debt, and (III) Sprint PCS' cost of capital.

                           (C) The Deferred Amount Note shall mature on the
                  earlier of (I) the date on which a Successor Manager is
                  qualified and assumes Affiliate's rights and obligations under
                  the Sprint Agreements, and (II) the date on which the
                  Operating Assets are purchased by a third-party buyer, or on
                  which a stock or other equity acquisition, merger,
                  consolidation or other transaction resulting in the indirect
                  transfer of the Operating Assets to a third-party buyer (an
                  "Indirect Transfer") is consummated.

                           (iii) In the event a Successor Manager assumes any of
         the obligations of Affiliate under the Sprint Agreements, such
         Successor Manager shall also assume the obligations under the Deferred
         Amount Note. In the event that the Operating Assets are sold to a third
         party buyer or an Indirect Transfer is consummated, the obligations of
         Affiliate under the Deferred Amount Note shall be subordinate to
         Borrower's obligations to its secured lenders.

                           (iv) After the two-year anniversary of the
         Acceleration, or earlier if a Successor Manager is appointed or if
         Sprint PCS is not serving as the Interim Manager, Sprint PCS will again
         retain the full Retained Amount.

                  (e) Payment of Obligations; Release and Assignment of Rights.
The term "Obligations" means the amount equal to the Obligations, after taking
into consideration any amounts received from the Guarantors.

                  If Sprint PCS purchases the Operating Assets or the Pledged
Equity as permitted under Section 6(a) or Section 10, and the Obligations have
been paid in full and the Credit Agreement and all Commitments have terminated
or been assigned to a Sprint Party: (i) the Guarantors will have no

                                       13

<PAGE>   14

right to any amounts paid by Sprint PCS pursuant to such purchase (except to the
extent such purchase is pursuant to Section 6(a) and the amount paid by Sprint
PCS exceeds the amount of the Obligations and is not payable to other creditors
of Borrower or Affiliate); (ii) the Administrative Agent will, at the election
of Sprint PCS, either release or assign to Sprint PCS all Security Interests in
the Collateral and all Additional Security Interests in the Additional
Collateral and release or assign to Sprint PCS all rights related to the Loan
Documents and the Guaranty Documents and all payments under the Loan Documents
and the Guaranty Documents; and (iii) the Guarantors will, at the election of
Sprint PCS, release or assign to Sprint PCS, any and all rights they have
against the Collateral and the Additional Collateral or arising out of any
payment to the Administrative Agent or any Sprint Party with respect to the Loan
Documents or the Guaranty Documents.

         SECTION 7. No Limits on Remedies. Nothing contained in this Consent and
Agreement shall limit any rights of the Administrative Agent or Lenders to
Accelerate. Except as expressly provided herein, nothing contained in this
Consent and Agreement shall limit any rights or remedies that the Administrative
Agent or the Lenders may have under the Loan Documents or applicable law. The
Administrative Agent may not sell, lease, assign, convey or otherwise dispose of
the Collateral other than as permitted under this Consent and Agreement.

         SECTION 8. Rights and Obligations of Interim Manager. The Interim
Manager may collect a reasonable management fee for its services; provided, that
if Sprint Spectrum or a Related Party of Sprint PCS acts as Interim Manager,
such management fee shall not exceed the direct expenses relating to Sprint
Spectrum or such Related Party employees for the actual time spent by such
employees when performing the function of Interim Manager and Sprint Spectrum's
or such Related Party's out-of-pocket expenses. Such direct expenses shall
include such employees' salaries and benefits, and the out-of-pocket and accrued
expenses allocated to such employees. If Sprint Spectrum is the Interim Manager,
the management fee will be paid out of the 92% Management Fee that Sprint PCS
pays under the Management Agreement, and will be in addition to the fees it
receives under the Services Agreement. Sprint PCS shall collect such management
fee by setoff against the fees and any other amounts payable to Affiliate under
the Sprint Agreements. The Interim Manager will be required to operate the
Service Area Network in accordance with the terms of the Sprint Agreements and
will be subject to all of the requirements and obligations of such agreements,
but will not be required to assume the existing liabilities of Affiliate.

         SECTION 9. Rights to Cure. Neither the provisions of this Consent and
Agreement nor any action of either Administrative Agent or Sprint PCS shall
require either Administrative Agent, any Lender or Sprint PCS to cure any
default of Affiliate under the Sprint Agreements or to perform under the Sprint
Agreements, but shall only give it the option to do so except to the extent
otherwise required by this Consent and Agreement. Sprint PCS may exercise its
rights under Section 11.6.3 of the Management Agreement upon an Event of
Termination, whether such situation arises while Affiliate, Sprint Spectrum, an
Administrative Agent Designee or a Sprint Spectrum Designee is acting as Interim
Manager and notwithstanding any other provision of this Consent and Agreement;
provided, that the right to reimbursement for any expenses incurred in
connection with such cure shall be unsecured and until such time as the
Obligations have been paid in full in cash and all commitments to advance credit
under the Credit Agreement have terminated or expired, the Person or Persons
entitled thereto shall not receive such reimbursement, except as specifically
provided in Section 4(b) or Section 5(b) of this


                                       14

<PAGE>   15

Consent and Agreement. Sprint PCS shall not be permitted to deduct or setoff
from its payments to Affiliate any such amounts it is not entitled to receive
under this Section and shall not take any action of any type to attempt to
collect such reimbursement and the failure to be so reimbursed shall not
constitute a Management Agreement Breach. In the event that Sprint PCS receives
any payments or distributions that it is not entitled to receive under this
Section, such payments shall be held in trust for, and promptly turned over to,
the parties entitled thereto. If Sprint PCS has designated a third party to take
action under Section 11.6.3 of the Management Agreement, before taking any such
action such third party shall enter into an agreement with Administrative Agent
providing that such third party agrees to the provisions of this Section 9 as if
it were a party hereto. Until such time as the Obligations have been paid in
full in cash and all commitments to advance credit under the Credit Agreement
have terminated or expired, Sprint PCS shall not be entitled to exercise any
other remedies under the Sprint Agreements, including, without limitation, the
remedy of terminating the Sprint Agreements (except to the extent permitted
under Sections 6(b)(ii)(A) and 12 of this Consent and Agreement) or the remedy
of withholding any payment set forth in Section 10 of the Management Agreement
(subject to Sprint PCS's rights of setoff or recoupment with respect to such
payments as permitted under Sections 2, 4(b) and 5(b) of this Consent and
Agreement). Until such time as the Obligations have been paid in full in cash
and all commitments to advance credit under the Credit Agreement have terminated
or expired, notwithstanding anything to the contrary contained in Section 2.3 of
the Management Agreement, in no event shall any Person other than Affiliate or a
Successor Manager be a manager or operator for Sprint PCS with respect to the
Service Area and neither Sprint PCS nor any of its Related Parties shall own,
operate, build or manage another wireless mobility communications network in the
Service Area, except to the extent provided in Sections 2.3(a), (b), (c) or (d)
of the Management Agreement and except to the extent that the Sprint Agreements
are terminated in accordance with Section 6(b)(ii)(A) of this Agreement. The
Administrative Agent acknowledges and agrees that Sprint PCS shall also have the
right to cure an Event of Default or to assist Affiliate in curing an Event of
Default but only to the extent Borrower has the right to so cure under the Loan
Documents, as applicable (it being understood that the act of Sprint PCS curing
an Event of Default shall not constitute an independent Event of Default unless
the act itself would otherwise constitute a Default (e.g. a sale of assets not
otherwise permitted by the Loan Documents)), including but not limited to Sprint
PCS's providing Borrower the funds necessary to operate or meet certain
financial covenants in the Loan Documents. The Administrative Agent shall have
the right to cure any Management Agreement Breach.

         SECTION 10. Sprint PCS's Right to Purchase Obligations, Operating
Assets, or Pledged Equity. (a) Following the Acceleration Date and until the
60-day anniversary of the filing of a bankruptcy petition by or with respect to
Borrower or Affiliate, Sprint PCS shall have the right to purchase the
Obligations under, and as defined in, the Credit Agreement, by repaying the
Obligations in full in cash. In the event that Sprint PCS purchases the
Obligations within 60 days immediately following the earlier of (i) the
Acceleration Date and (ii) the date of the filing of a bankruptcy petition by or
with respect to Borrower or Affiliate, Sprint PCS may in lieu of purchasing the
total amount of the Obligations, purchase all Obligations other than the accrued
interest with respect thereto for a purchase price equal to the amount of the
Obligations other than such accrued interest and any fees and expenses that are
unreasonable, in which case, such accrued interest and unreasonable fees and
expenses shall remain due and owing by Affiliate to the Lenders.

                  (b) In the event that the Administrative Agent acquires the
Operating Assets or takes title to the Pledged Equity, Sprint PCS shall have the
right to purchase the Operating Assets or the


                                       15

<PAGE>   16

Pledged Equity from the Administrative Agent during the limited period of time
provided in and otherwise in accordance with this Section 10(b) by paying to the
Administrative Agent in cash an amount equal to the sum of the aggregate amount
paid (by credit against the Obligations or otherwise) by the Administrative
Agent or the Lenders for the Operating Assets or Pledged Equity, as the case may
be, plus the aggregate amount of any remaining unpaid Obligations.
Administrative Agent shall give Sprint PCS notice of any acquisition of the
Operating Assets or the Pledged Equity by the Administrative Agent promptly
following the date of final consummation of such acquisition (the "Acquisition
Notice"). Sprint PCS shall, within 60 days of receipt of a valid Acquisition
Notice, give the Administrative Agent (and Borrower in the case of a purchase of
the Pledged Equity) notice of its intent to exercise its purchase right under
this Section 10(b). In the event Sprint PCS gives the Administrative Agent
written notice of its intent to purchase the Operating Assets or the Pledged
Equity, the Administrative Agent agrees that it shall provide Sprint PCS the
right to purchase the Operating Assets or Pledged Equity, as the case may be,
until the earlier to occur of (i) expiration of the period consisting of 120
days after Sprint PCS' receipt of a valid Acquisition Notice (or such later date
that shall be provided for in the purchase agreement and acceptable to the
Administrative Agent in its sole discretion to close the purchase of the
Operating Assets or Pledged Equity) or (ii) receipt by Administrative Agent from
Sprint PCS of written notice that Sprint PCS has determined not to proceed with
the closing of the purchase of the Operating Assets or Pledged Equity. If Sprint
PCS at any time purchases the Operating Assets or Pledged Equity as permitted
under this Section 10, the Administrative Agent and the Guarantors will release
or assign their interest in the Collateral, the Loan Documents and the Guaranty
Documents as described in Section 6(e) upon payment in full of the aggregate
amount of the Obligations. Notwithstanding the foregoing, in the event that a
bankruptcy petition is filed by or with respect to Affiliate, Sprint PCS shall
again have the right to purchase the Operating Assets or the Pledged Equity from
the Administrative Agent by repaying the Obligations in full in cash, by giving
the Administrative Agent notice of its intent to exercise such purchase right no
later than 60 days following the date of filing of such bankruptcy petition.

                  (c) If at any time during the period described in Section
10(a) or 10(b) above or thereafter the Administrative Agent receives any
purchase offer for the Operating Assets, the Pledged Equity or the Obligations,
as applicable, that is acceptable to the Administrative Agent, the
Administrative Agent shall exercise reasonable efforts to obtain the consent of
the offeror to deliver a copy of such offer to Sprint PCS and Sprint PCS shall
have the right to purchase the Operating Assets, the Pledged Equity or the
Obligations, as applicable, on terms and conditions at least as favorable to the
Administrative Agent as the terms and conditions proposed in such offer so long
as within 14 Business Days after Sprint PCS's receipt of such other offer Sprint
PCS offers to purchase the Operating Assets, the Pledged Equity or the
Obligations, as applicable, and so long as the conditions of Sprint PCS's offer
and the amount of time it will take Sprint PCS to effect such purchase is
acceptable to the Administrative Agent and the Lenders.

                  (d) If Sprint PCS at any time purchases the entirety of the
Obligations as provided in this Section 10, the Administrative Agent shall
assign and transfer or cause the Lenders to assign and transfer to Sprint PCS
all rights and interests in, to and under all of the Loan Documents, including
but not limited to all security interests, liens, financing statements,
guaranties (including the Guaranty Documents) and other credit enhancements
related to such Loan Documents, and all rights and claims thereunder
(collectively referred to as the "Loan Document Rights"). If Sprint PCS
purchases all Obligations other than accrued interest (as permitted in the
second sentence of Section 10(a) above),


                                       16

<PAGE>   17

then the Administrative Agent shall assign and transfer or cause the Lenders to
assign and transfer to Sprint PCS all Loan Document Rights, except that if
Sprint PCS receives payment in full of all Obligations due under the Loan
Documents (including the amount it did not pay the Administrative Agent, as
permitted in the second sentence of Section 10(a) above), it shall pay such
amount to the Administrative Agent unless the Administrative Agent has already
received payment of such amount. If Sprint PCS at any time purchases the
entirety or less than all of the Obligations, the Guarantors will release any
and all rights they have against the Collateral or arising out of any payment to
the Administrative Agent or any Sprint Party with respect to the Loan Documents
or their Guaranty Documents.

         SECTION 11. Foreclosure. Upon the Administrative Agent or any Lender or
any other Person that meets the Successor Manager Requirements acquiring the
Operating Assets and the Sprint Agreements, then such Person shall be entitled
to exercise any and all rights of Affiliate under the Sprint Agreements in
accordance with the terms of the Sprint Agreements and each Sprint Party will
thereupon comply in all respects with such exercise by such Person and perform
its obligations under the Sprint Agreements and this Consent and Agreement for
the benefit of such Person. Each Sprint Party agrees that the Administrative
Agent or any Lender may (but shall not be obligated to), subject to and in
accordance with the terms of this Consent and Agreement, assign its rights and
interests acquired in the Operating Assets and the Sprint Agreements to any
buyer or transferee thereof and, in the event the buyer wishes to become a party
to the Sprint Agreements and such buyer satisfies the Successor Manager
Requirements, such buyer shall be bound by the Sprint Agreements; provided, that
buyer shall have no responsibility or liability to any Person other than a
Sprint Party and a Related Party of a Sprint Party arising out of Affiliate's
operations prior to the date buyer becomes bound by the Sprint Agreements. In
such case the Sprint Agreements shall remain in full force and effect with the
buyer as Successor Manager and this Consent and Agreement shall remain in full
force and effect for the benefit of the Successor Manager and any Person
providing senior secured debt financing to such Successor Manager if required by
such Person. Sprint PCS agrees, with respect to any past failure of Affiliate to
perform any obligation under the Sprint Agreements, that the Successor Manager
shall have the same amount of time to perform such obligation that Affiliate had
under the Sprint Agreements, with the performance period commencing on the date
on which the buyer becomes a Successor Manager. Sprint PCS shall permit the
performance period set forth in the Management Agreement to be extended for such
period of time that Sprint PCS believes is reasonable to allow Successor Manager
to perform such unperformed obligations.

         SECTION 12. Trademarks and Service Marks. In the event the
Administrative Agent forecloses on its security interest in the License
Agreements and transfers the License Agreements to a Person who does not meet
the Successor Manager Requirements, then Sprint PCS shall have the right to
terminate the License Agreements and cause the Administrative Agent to release
its security interest in the License Agreements immediately prior to such
transfer.

         SECTION 13. Interim Manager and Successor Manager Requirements.  To
qualify as an Interim Manager or a Successor Manager, the Person must satisfy
each of the following "Successor Manager Requirements," as applicable:

                  (a) The Person must not during the three-year period
         immediately preceding the date of determination have materially
         breached any material agreement with Sprint Spectrum


                                       17


<PAGE>   18

         or its Related Parties that resulted in the exercise of a termination
         right or in the initiation of judicial or arbitration proceedings;

                  (b) The Person must not be one of the Persons identified on
         Schedule 13 (a "Schedule 13 Person"); provided, that no Other Manager
         under any Sprint PCS Management Agreement may be identified on Schedule
         13;

                  (c) In the case of a Successor Manager, the Person must meet a
         reasonable Person's credit criteria (taking into consideration the
         circumstances), it being understood that such criteria is satisfied if
         the financial projections contained in the business plan such Person
         submits to Sprint PCS shows the ability to service its indebtedness and
         meet the build-out requirements contained in the Build-out Plan; and

                  (d) The Person must agree to be bound by the terms of the
         Sprint Agreements as if an original party thereto; provided, in the
         case of an Interim Manager, the Person must also execute a separate
         confidentiality agreement in the form attached as Exhibit A with such
         changes thereto as may be reasonably requested by the parties to the
         agreement, but the Person is not required to assume the existing
         liabilities of the Affiliate.

         The Administrative Agent, each Lender and each of their wholly-owned
subsidiaries or entities who wholly-own such entities shall be deemed to satisfy
Sections 13(a), (b) and (c) of the preceding "Successor Management
Requirements".

         SECTION 14. Management Agreement. Sprint PCS agrees that it will not
exercise its right under the Management Agreement to purchase the Operating
Assets or to sell the Disaggregated License to Affiliate if before, or after
giving effect to such exercise, there would exist a Default or Event of Default
under the Credit Agreement, unless Sprint PCS pays the aggregate amount of the
Obligations as a condition of the exercise of such right and the Credit
Agreement shall have been terminated in connection with such payment. Sprint PCS
agrees that until the Obligations have been paid in full in cash and all
commitments to advance credit under the Credit Agreement have terminated or
expired, a failure to pay any amount by any Related Party of the Affiliate under
any agreement with Sprint PCS or any of its Related Parties (other than the
Management Agreement, the Services Agreement or the License Agreements) shall
not constitute a Management Agreement Breach for any purpose. Subject to
regulatory approval in connection with any such sale, Sprint PCS agrees that it
shall always maintain the ability to sell the Disaggregated License in
accordance with this Consent and Agreement. Sprint PCS shall own at least 10 MHZ
of Spectrum in the Service Area until the first to occur of the following
events: (i) the Obligations have been paid in full in cash and all commitments
to advance credit under the Credit Agreement have terminated or expired, (ii)
the sale by Sprint PCS of the Spectrum pursuant to this Consent and Agreement
shall be effected, (iii) the sale of the Operating Assets pursuant to this
Consent and Agreement, and (iv) the termination of the Management Agreement.
Sprint PCS acknowledges that the financing provided to Borrower pursuant to the
Loan Documents and the proposed capital contribution from Alamosa PCS Holdings,
Inc. ("Alamosa Holdings"), the sole stockholder of Borrower, following its
initial public offering of common stock contemplated by the registration
statement of Borrower filed with the Securities and Exchange Commission on
October 29, 1999, as amended, comply with Section 1.7 of the Management
Agreement, as amended by Addendum II of the Management Agreement ("Section
1.7"), and that


                                       18


<PAGE>   19

Section 11.3.6 of the Management Agreement shall no longer be applicable with
respect to such financing so long as Borrower makes capital contributions to
Affiliate in the amounts and by the deadlines set forth in Section 1.7.
Notwithstanding anything to the contrary contained in Section 12.2 of the
Management Agreement, the Administrative Agent, the Lenders, and any Successor
Manager or buyer of the Operating Assets or Disaggregated License shall be
permitted to disclose Confidential Information (as defined in the Management
Agreement) (i) to the extent required by law, rule or regulation, (ii) to any
regulator or any regulatory body regulating such entity, (iii) to any rating
agency in connection with requirements applicable to such Person and (iv) to the
lawyers and accountants for any such Persons.

         SECTION 15. Administrative Agent and Eligible Assignees. The
Administrative Agent and each Lender must be an Eligible Assignee. "Eligible
Assignee" shall mean and include a commercial bank, financial institution, other
"accredited investor" (as defined in Regulation D of the Securities Act) other
than individuals, or a "qualified institutional buyer" as defined in rule 144A
of the Securities Act; provided, that prior to the 61st day after the filing of
a bankruptcy petition by or with respect to Affiliate in no event may any Person
that is engaged in or that controls, is controlled by or is under common control
with any Person engaged in, the telecommunications service business in the
United States (other than Sprint Corporation and its subsidiaries), be an
Eligible Assignee, it being understood that no small business investment
corporation that is ultimately owned by an Eligible Assignee that is subject to
Regulation Y shall be deemed to be controlled by or under common control with
such Eligible Assignee; and provided further, that after the filing of such
bankruptcy petition in no event may a Schedule 13 Person be an Eligible
Assignee.

         SECTION 16. Sprint Party Representations. Each Sprint Party represents
and warrants to the Administrative Agent, as of the Closing Date (a) its
execution, delivery and performance of this Consent and Agreement has been duly
authorized by all necessary corporate and partnership action, and does not and
will not require any further consents or approvals that have not been obtained,
or violate any provision of any law, regulation, order, judgment, injunction or
similar matters or materially breach any agreement presently in effect with
respect to or binding on it; provided, that the transfer of Spectrum as
contemplated under this Consent and Agreement will require regulatory approval
(which each Sprint Party agrees to use its commercially reasonable efforts to
obtain); (b) this Consent and Agreement is a legal, valid and binding obligation
of such Person enforceable against it in accordance with its terms, except that
(i) such enforceability may be limited by applicable bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws affecting the
enforcement of creditors' rights generally, and (ii) the remedy of specific
performance and injunctive and other forms of equitable relief may be limited by
equitable defenses and by the discretion of the court before which any
proceeding may be brought; (c) the Sprint Agreements are in full force and
effect and have not been amended, supplemented or modified; (d) as of the date
of execution hereof, to the knowledge of the Sprint Parties, no Event of
Termination has occurred and is continuing (without regard to any requirement of
the delivery of written notice necessary to the occurrence of an Event of
Termination under Section 11.3 of the Management Agreement); (e) on the date the
Management Agreement was executed Sprint PCS owned, and on the date hereof
Sprint PCS owns, 10 MHz or more of Spectrum in the Service Area; and (f) the
only existing agreements or arrangements between Borrower or Affiliate, on the
one hand, and Sprint Corporation or any of its subsidiaries, on the other hand,
are the Management Agreement, the Services Agreement, the License Agreements,
this Consent and Agreement and the Deferred Amount Note.

         SECTION 17. Administrative Agent Representations. The Administrative
Agent represents and warrants to Sprint PCS, as of the Closing Date (a) its
execution, delivery and performance of this Consent and Agreement has been duly
authorized by all necessary corporate action, and does not and will not require
any further consents or approvals that have not been obtained, or violate any
provision of any law, regulation, order, judgment, injunction or similar matters
or materially breach any agreement presently in effect with respect to or
binding on it; (b) this Consent and Agreement is a legal, valid and binding
obligation of the Administrative Agent enforceable against it in accordance with
its terms, except that (i) such enforceability may be limited by applicable
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws affecting the enforcement of creditors' rights generally, and (ii)
the remedy of specific performance and injunctive and other forms of equitable
relief may be limited by equitable defenses and by the discretion of the court
before which any proceeding may be brought; (c) at the time of the execution
hereof, Administrative Agent is the only Lender; (d) as of the date of execution
hereof, to the knowledge of the Administrative Agent, no Event of Default has
occurred and is continuing; and (e) the Guaranty Documents have been duly

         SECTION 18. Successors and Assigns. This Consent and Agreement shall be
binding upon the successors and assigns of the parties hereto and shall inure,
together with the rights and remedies of the parties hereunder, to the benefit
of their respective successors and assigns. In the event the Sprint PCS Network
is sold in accordance with the Management Agreement, the buyer thereof will
assume the obligations of the Sprint Parties hereunder and under all the other
Sprint Agreements other than the Sprint Trademark and Service Mark License
Agreement; provided, however, the buyer of the Sprint PCS Network shall enter
into an agreement with Affiliate on substantially the same terms as the Sprint
Trademark and Service Mark License Agreement with respect to such buyers'
trademarks, service marks, brands, etc. In the event a Successor Manager becomes
a party to the Sprint Agreements as provided in this Agreement, this Consent and
Agreement shall remain in full force and effect for the benefit of the Successor
Manager and any Person providing senior secured debt financing to such Successor
Manager if required by such Person.

         SECTION 19. Amendment. Neither this Consent and Agreement nor any
provision herein may be waived except pursuant to an agreement or agreements in
writing entered into by Sprint PCS, the Administrative Agent, Borrower and
Affiliate, and neither this Consent and Agreement nor any provision herein may
be amended or modified except pursuant to an agreement or agreements in writing
entered into by Sprint PCS, the Administrative Agent, Borrower and Affiliate;
provided, however, that no consent of Borrower or Affiliate shall be necessary
for any amendment or modification to this Consent and Agreement made pursuant to
or in accordance with Section 25 hereof, unless such amendment or modification
could reasonably be expected to be materially adverse to Borrower or Affiliate.
The Administrative Agent and each Lender (and its successors and assigns) shall
be bound by any modification or amendment authorized by this Section 19. No
amendment or waiver or effective amendment or waiver entered into in violation
of this Section 19 shall be valid.

         SECTION 20. APPLICABLE LAW. THIS CONSENT AND AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK.

All notices and other communications given to any party hereto in accordance
with the provisions of this Consent and Agreement shall be deemed to have been
given on the date of receipt if delivered by hand or overnight courier service
or sent by telecopy, or on the date five (5) business days after dispatch by
certified or registered mail if mailed, in each case delivered, sent or mailed
(properly addressed) to such party as provided in this Section 21 or in
accordance with the latest unrevoked direction from such party given in
accordance with this Section 21.

         SECTION 22. Counterparts. This Consent and Agreement may be executed in
two or more counterparts, each of which shall constitute an original but all of
which when taken together shall constitute but one contract.

         SECTION 23. Severability. Any provision of this Consent and Agreement
that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. The parties shall
endeavor in good faith negotiations to replace the


                                       23

invalid, illegal or unenforceable provision with valid provisions the economic
effect of which is as close as possible to that of the invalid, illegal or
unenforceable provision.

         SECTION 24. Termination. This Consent and Agreement shall terminate and
be of no further force and effect upon the first to occur of the following: (i)
the Obligations are paid in full and the Credit Agreement and all Commitments
are terminated; and (ii) the Sprint Agreements terminate.

         SECTION 25. Amendments to Form Consent and Agreement. If Sprint PCS
modifies or amends the form of Consent and Agreement it enters into with another
lender in connection with a loan to an Other Manager that is syndicated or
intended to be syndicated (i.e., a loan sold or participated, or intended to be
sold or participated, in whole or in part to at least three financial
institutions or investment funds) and where the pops in the Service Area of the
Other Manager exceed 5 million, then Sprint PCS agrees to give the
Administrative Agent the right to so amend this Consent and Agreement, subject
to the provisions of clauses (a), (b) and (c) below. Sprint PCS agrees to give
the Administrative Agent written notice of such modifications and amendments
and, at the request of Administrative Agent, to amend this Consent and Agreement
in the same manner; provided, that: (a) Sprint PCS will not modify this Consent
and Agreement to incorporate changes made for the benefit of a lender because of
circumstances related to a particular Other Manager, subject to the limitations
set forth below; (b) the Administrative Agent must agree to make all (or none)
of the changes made for the other lender and the Other Manager, unless Sprint
PCS agrees to allow the Administrative Agent to make only some of the changes;
and (c) if such amendment to this Consent and Agreement could reasonably be
expected to be materially adverse to Borrower or Affiliate, such amendment shall
not be made without the prior written consent of Borrower and Affiliate
(although the Borrower's and Affiliate's withholding of such consent will result
in none of the changes being made to this Consent and Agreement because of the
requirements of clause (b) above).

         For purposes of subsection (a) in the preceding paragraph, Sprint PCS
will not deem the following changes to be made because of circumstances related
to a particular Other Manager: (i) any form of recourse to Sprint PCS or other
similar form of credit enhancement; (ii) any change in Sprint PCS's right to
purchase Operating Assets or Obligations; (iii) any change in the Affiliate's,
Administrative Agent's or Lenders' right to sell the Collateral or purchase the
Disaggregated License (including, without limitation, any rights of first
refusal and the purchase price of the Disaggregated License); (iv) any change in
the ownership status, terms of usage or amount of Disaggregated License utilized
by Affiliate; (v) any material change in the flow of revenues between Sprint
Spectrum and Affiliate excluding changes related to the pricing of direct or
indirect fees, but including any subordination of direct or indirect fees or
other amounts or costs due under the Sprint Agreements or hereunder to Sprint
PCS; (vi) any change to obligations required to be assumed by, or qualifications
for, any Interim or Successor Manager, including changes in the time period or
terms under which Sprint PCS agrees to remain as Interim Manager; (vii) any
changes in confidentiality, non-compete or Eligible Assignee language, including
changes to Schedule 13; (viii) any clarifications of FCC compliance issues; (ix)
the issuance of legal opinions; (x) any change in the circumstances under, or
procedures by which, an Interim Manager or Successor Manager is appointed; or
(xi) any change to this Section 25.

                  1.      It will not use the proceeds from any of the Loan
                          Documents or from any other loan or extension of
                          credit to which this Consent and Agreement relates
                          for any purpose other than to contribute or loan such
                          proceeds to Affiliate or to Texas Telecommunications,
                          LP.

                  2.      Borrower agrees to promptly give Sprint PCS a copy of
