     NOW, THEREFORE, in consideration of the premises and the agreements,
provisions and covenants herein contained, and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties agree as follows:


                                   SECTION 1

          (B)  Revolving Loans.  Each Lender, severally and not jointly,
               ---------------

<PAGE>

               (1)  as a Base Rate Loan, at the sum of the Base Rate plus the
                                                                     ----
Base Rate Margin applicable from time to time as provided in Subsection 1.2(B);
or

               (2)  as a LIBOR Loan, for the applicable Interest Period (as

applicable on the first day of the applicable Interest Period or as applicable

                                          ----

          (B)  Applicable Margins.  Initially, and continuing through the day
               ------------------
immediately preceding the first Adjustment Date occurring after the first
consecutive four (4) fiscal quarter period in which Borrower achieves positive
Operating Cash Flow for such period, the applicable Base Rate Margin and LIBOR
Margin shall be 2.250% and 3.500% per annum, respectively.  Commencing on such
Adjustment Date, the applicable Base Rate Margin and LIBOR Margin shall be for
each Calculation Period the applicable per annum percentage set forth in the
pricing table below opposite the Total Leverage Ratio of Borrower; provided,
                                                                   --------

          (C)  Interest Periods. Each LIBOR Loan may be obtained for a one
               ----------------
(1), two (2), three (3) or six (6) month period (each such period being an
"Interest Period").  With respect to all LIBOR Loans:

               (i)   the Interest Period will commence on the date that the
     LIBOR Loan is made or the date on which any portion of the Base Rate Loan
     is converted into a LIBOR Loan, or, in the case of immediately successive
     Interest Periods, each successive Interest Period shall commence on the day
     on which the immediately preceding Interest Period expires;

               (ii)  if the Interest Period would otherwise expire on a day that
     is not a Business Day, then it will expire on the next Business Day,
     provided, that if any Interest Period would otherwise expire on a day that
     --------
     is not a Business Day and such day is a day of a calendar month after which
     no further Business Day occurs in such month, such Interest Period shall
     expire on the Business Day next preceding such day;

               (iii) any Interest Period that begins on the last Business Day
     of a calendar month or on a day for which there is no numerically
     corresponding day in the last calendar month in such Interest Period shall
     end on the last Business Day of the last calendar month in such Interest
     Period;

               (iv)  no Interest Period shall be selected for any Loan if, in
     order to make repayments required pursuant to Subsection 1.6(D) in
     connection with scheduled

** Greater than

     reductions of the Loan Commitments pursuant to Subsection 1.6(A), repayment
     of all or any portion of such Loan prior to the expiration of such Interest
     Period would be necessary; and

               (v) no Interest Period shall extend beyond the date set forth in
     clause (iii) of the definition of the term "Expiration Date."

          (D)  Calculation and Payment.  Interest on all LIBOR Loans shall be
               -----------------------
calculated daily on the basis of a three hundred sixty (360) day year for the
actual number of days elapsed. The interest on the Base Rate Loan and all other
Obligations and the amount of any fees set forth in Subsection 1.4 shall be
calculated daily on the basis of a three hundred sixty-five or -six (365-6) day
year for the actual number of days elapsed. The date of funding or conversion to
a Base Rate Loan and the first day of an Interest Period with respect to a LIBOR
Loan shall be included in the calculation of interest. The date of payment of
any Loan and the last day of an Interest Period with respect to a LIBOR Loan
shall be excluded from the calculation of interest; provided, if a Loan is
                                                    --------
repaid on the same day that it is made, one (1) day's interest shall be charged.

          Interest accruing on the Base Rate Loan is payable in arrears on each
of the following dates or events: (i) the last day of each calendar quarter,
(ii) the prepayment of such Loan (or portion thereof) and (iii) the Expiration
Date, whether by acceleration or otherwise.  Interest accruing on each LIBOR
Loan is payable in arrears on each of the following dates or events: (i) the
last day of each calendar quarter, (ii) the last day of each applicable Interest
Period, (iii) the prepayment of such Loan (or portion thereof) and (iv) the
Expiration Date, whether by acceleration or otherwise.

          (E)  Default Rate of Interest.  At the election of Administrative
               ------------------------
Agent or Requisite Lenders, after the occurrence of an Event of Default and for
so long as it continues, all Loans and other Obligations shall bear interest at
variable rates that are two percent (2.000%) in excess of the rates otherwise in
effect, including, without limitation, rates in effect pursuant to the proviso
in the second sentence of Subsection 1.2(B), with respect to such Loans and
other Obligations.

          (F)  Excess Interest.  Under no circumstances will the rate of
               ---------------
interest chargeable be in excess of the maximum amount permitted by law.  If any
such excess interest is charged and paid in error, then the excess amount will
be promptly refunded.

          (G)  Selection, Conversion or Continuation of Loans; LIBOR
               -----------------------------------------------------
Availability.  Provided that no Default or Event of Default has occurred and
------------
is then continuing, Borrower shall have the option to (i) select all or any part
of a new borrowing to be a LIBOR Loan in a principal amount equal to $3,000,000
or any whole multiple of $500,000 in excess thereof, (ii) convert at any time
all or any portion of the Base Rate Loan in a principal amount equal to
$3,000,000 or

                                       5
<PAGE>

any whole multiple of $500,000 in excess thereof into one or more LIBOR Loans,
(iii) upon the expiration of any Interest Period, convert all or any part of any
LIBOR Loan into the Base Rate Loan, and (iv) upon the expiration of its Interest
Period, continue any LIBOR Loan in a principal amount of $3,000,000 or any whole
multiple of $500,000 in excess thereof into one or more LIBOR Loans for such new
Interest Period(s) as selected by Borrower. Each LIBOR Loan must be made under
either the Term Loan Facility or the Revolving Loan Facility, but may not be
made under both concurrently. During any period in which any Default or Event of
Default is continuing, as the Interest Periods for LIBOR Loans then in effect
expire, such Loans shall be converted into the Base Rate Loan and the LIBOR
option will not be available to Borrower until all Events of Default are cured
or waived. Notwithstanding the foregoing, there may be no more than a total of
six (6) Loans outstanding under the Facilities at any one time (including, as a
single Loan, all amounts under a single Facility accruing interest at the Base
Rate).

     1.3  Notice of Borrowing, Conversion or Continuation of Loans.
          --------------------------------------------------------

          Whenever Borrower desires to request a Loan pursuant to Subsection 1.1
or to convert or continue Base Rate or LIBOR Loans pursuant to Subsection
1.2(G), Borrower shall give Administrative Agent irrevocable prior written
notice in the form attached hereto as Exhibit 1.3 (a "Notice of
Borrowing/Conversion/Continuation"), (i) if requesting a borrowing of,
conversion to or continuation of the Base Rate Loan (or any portion thereof),
not later than 11:00 a.m. (Denver time), one (1) Business Day before the
proposed borrowing, conversion or continuation is to be effective or (ii), if
requesting a borrowing of, a conversion to or a continuation of a LIBOR Loan,
not later than 11:00 a.m. (Denver time), three (3) Business Days before the
proposed borrowing, conversion or continuation is to be effective. Each Notice
of Borrowing/Conversion/Continuation shall specify (a) the Loan (or portion
thereof) to be converted or continued and, with respect to any LIBOR Loan to be
converted or continued, the last day of the current Interest Period therefor,
(b) the effective date of such borrowing, conversion or continuation (which
shall be a Business Day), (c) the principal amount of such Loan to be borrowed,
converted or continued, (d) the Interest Period to be applicable to any new
LIBOR Loan, and (e) the Facility under which such borrowing, conversion or
continuation is to be made. In the event Borrower fails to elect a LIBOR Loan

amount that Borrower is required, pursuant to Section 1.8, to apply mandatory
repayments to be made pursuant to Subsection 1.7 (B), (C), (D), (E), (F) or (G)
to the Revolving Loan Facility (whether or not any Revolving Loans are then
outstanding and available to be repaid). All reductions provided for in this
Subsection 1.6(B) shall be in addition to (and shall not serve to reduce the
amount or date of) the scheduled reductions provided for in Subsection 1.6(A)
and the voluntary reductions provided for in Subsection 1.6(C) and, accordingly,
may result in the termination of the Revolving Loan Commitment prior to the date
set forth in clause (iii) of the definition of the term "Expiration Date."

Revolving Loan Commitment.  Each reduction shall be in a minimum amount of at
least $1,000,000, or any whole multiple of $500,000 in excess thereof, and shall
be applied as to each Lender based upon its Pro Rata Share.  Notwithstanding the
foregoing, no reduction shall be permitted if, after giving effect thereto and

<PAGE>

made therewith, the aggregate principal balance of the Loans then outstanding
would exceed the Revolving Loan Commitment as so reduced. Each reduction
pursuant to this Subsection 1.6(C) may be used as a one-time credit against the
next succeeding scheduled reduction(s) required pursuant to Subsection 1.6(A).

          (D)  Mandatory Repayments.  On the date of each Revolving Loan
               --------------------
Commitment reduction provided for in this Subsection 1.6, Borrower shall repay
Revolving Loans in an amount at least sufficient to reduce the aggregate
principal balance of Revolving Loans then outstanding to the amount of the
Revolving Loan Commitment as so reduced.  If at any time the aggregate
outstanding amount of Revolving Loans exceeds the Available Revolving Loan
Commitment, Borrower shall repay Revolving Loans in an amount at least
sufficient to reduce the aggregate principal balance of Revolving Loans then
outstanding to the amount of the Available Revolving Loan Commitment, and until
such repayment is made, Lenders shall not be obligated to make Loans.  Any
repayments pursuant to this Subsection 1.6(D) shall be applied in accordance
with Subsection 1.8, and shall be accompanied by accrued interest on the amount
repaid and any amount required pursuant to Subsection 1.4(C).

purposes of this Subsection 1.7(B), Excess Cash Flow shall be calculated on a
consolidated basis for Borrower and its Restricted Subsidiaries, but excluding
the Unrestricted Subsidiary; provided, however, that the results of Texas
                             --------  -------

however, that in the event of an Asset Disposition by Texas Unwired, prepayment

fees, costs and expenses actually incurred in connection with such equity

Asset Disposition by Texas Unwired, prepayment pursuant to this Subsection
1.7(F) will only be required in proportion to LA Unwired's percentage ownership

                                       12
<PAGE>

outstanding under the Revolving Loan Facility and then to Loans outstanding

first be applied to the Base Rate Loan and then to such LIBOR Loans as Borrower
and Administrative Agent shall agree. All repayments required or permitted
hereunder shall be accompanied by payment of all applicable Breakage Fees and
accrued interest on the amount repaid. All repayments applied to Loans
outstanding under the Term Loan Facility shall be applied to principal
installments in the inverse order of maturity.

     1.9  Loan Account.  Administrative Agent will maintain loan account
          -------------
records for (i) all Loans, interest charges and payments thereof, (ii) the
charging and payment of all fees, costs and expenses and (iii) all other debits
and credits pursuant to this Agreement.  The balance in the loan accounts shall
be presumptive evidence of the amounts due and owing to Lenders, provided that
                                                                 --------
any failure by Administrative Agent to maintain such records shall not limit or
affect Borrower's obligation to pay.  During the continuance of an Event of
Default, Borrower irrevocably waives the right to direct the application of any
and all payments and Borrower hereby irrevocably agrees that Administrative
Agent shall have the continuing exclusive right to apply and reapply payments in
any manner it deems appropriate.

     1.10 Changes in LIBOR Rate Availability.  If with respect to any
          ----------------------------------
proposed Interest Period, Administrative Agent or any Lender (after consultation
with Administrative Agent) determines that deposits in dollars (in the
applicable amount) are not being offered to each Lender in the relevant market
for such Interest Period, Administrative Agent shall forthwith give notice
thereof to Borrower and Lenders, whereupon and until Administrative Agent
notifies Borrower that the circumstances giving rise to such situation no longer
exist, the obligations of any affected Lender to make its portion of such type
of LIBOR Loan shall be suspended.

          If the introduction of, or any change in, any Applicable Law or any
change in the interpretation or administration thereof by any Governmental
Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender with any request or
directive (whether or not having the force of law) of any such Governmental
Authority, central bank or comparable agency, shall make it unlawful or
impossible for one or more Lenders to honor its obligations hereunder to make or
maintain any LIBOR Loan, such Lender shall promptly give notice thereof to
Administrative Agent, and Administrative Agent shall promptly give notice
thereof to Borrower and all other Lenders. Thereafter, until Administrative
Agent notifies Borrower that such circumstances no longer exist, (i) the
obligations of Lenders to make LIBOR Loans and the right of Borrower to convert
any Loan or continue any Loan as a LIBOR Loan shall be suspended and (ii) if any
Lender may not lawfully continue to maintain a LIBOR Loan to the end of the then
current Interest Period applicable thereto, such Loan shall immediately be
converted to the Base Rate Loan.

     1.11  Capital Adequacy and Other Adjustments.
           --------------------------------------

           (A) If the introduction of or the interpretation of any law, rule, or
regulation would increase the reserve requirement or otherwise increase the cost
to any Lender of making or maintaining a LIBOR Loan, then Administrative Agent,
on behalf of all affected Lenders, shall submit a certificate to Borrower
setting forth the amount and demonstrating the calculation of such increased
cost. Borrower shall pay the amount of such increased cost to Administrative
Agent for the benefit of the affected Lenders within fifteen (15) days after
receipt of such certificate. Such certificate shall, absent manifest error, be
final, conclusive and binding for all purposes. There is no limitation on the
number of times such a certificate may be submitted.

           (B) In the event that any Lender shall have determined that the
adoption after the date hereof of any law, treaty, governmental (or quasi-
governmental) rule, regulation, guideline or order regarding capital adequacy,
reserve requirements or similar requirements or compliance by any Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy, reserve requirements or similar requirements (whether or not
having the force of law and whether or not failure to comply therewith would be
unlawful) from any central bank or governmental agency or body having
jurisdiction does or shall have the effect of increasing the amount of capital,
reserves or other funds required to be maintained by such Lender or any
corporation controlling such Lender and thereby reducing the rate of return on
such Lender's or such corporation's capital as a consequence of its obligations
hereunder, then Borrower shall from time to time within fifteen (15) days after
notice and demand from such Lender (together with the certificate referred to in
the next sentence and with a copy to Administrative Agent) pay to Administrative
Agent, for the account of such Lender, additional amounts sufficient to
compensate such Lender for such reduction.  A certificate as to the amount of
such cost and showing the basis of the computation of such cost submitted by
such Lender to Borrower and Administrative Agent shall, absent manifest error,
be final, conclusive and binding for all purposes.  There is no limitation on
the number of times such a certificate may be submitted.

     1.12  Optional Prepayment/Replacement of Lender in Respect of Increased
           -----------------------------------------------------------------
Costs.  Within fifteen (15) days after receipt by Borrower of written notice
-----
and demand from any Lender (an "Affected Lender") for payment of additional
costs as provided in Subsection 1.11, Borrower may, at its option, notify
Administrative Agent and such Affected Lender of its intention to do one of the
following:

           (A) Borrower may obtain, at Borrower's expense, a replacement Lender
("Replacement Lender") for such Affected Lender, which Replacement Lender shall
be reasonably satisfactory to Administrative Agent.  In the event Borrower
obtains a Replacement Lender within ninety (90) days following notice of its
intention to do so, the Affected Lender shall sell and assign its Loans and its
obligations under the Loan Commitments to such Replacement Lender, provided
                                                                   --------

                                       14
<PAGE>

that Borrower has reimbursed such Affected Lender for its increased costs for
which it is entitled to reimbursement under this Agreement through the date of
such sale and assignment; or

           (B) Borrower may prepay in full all outstanding Obligations owed to
such Affected Lender and terminate such Affected Lender's Pro Rata Share of the
Loan Commitments, in which case the Loan Commitments will be permanently reduced
by the amount of such Pro Rata Share.  Borrower shall, within ninety (90) days
following notice of its intention to do so, prepay in full all outstanding
Obligations owed to such Affected Lender (including all applicable Breakage Fees
and such Affected Lender's increased costs for which it is entitled to
reimbursement under this Agreement through the date of such prepayment), and
terminate such Affected Lender's obligations under the Loan Commitments.  Any
such prepayment pursuant to this Subsection 1.12(B) shall be applied in
accordance with Subsection 1.8 and shall be accompanied by payment of all
applicable Breakage Fees and accrued interest on the amount repaid.

     1.13  Taxes.
           -----

           (A)  No Deductions.  Any and all payments or reimbursements made
                -------------
hereunder or under the Notes shall be made free and clear of and without
deduction for any and all taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto (all such taxes, levies,
imposts, deductions, charges or withholdings and all liabilities with respect
thereto excluding such taxes imposed on net income, herein "Tax Liabilities"),
excluding, however, taxes imposed on the net income of a Lender or
Administrative Agent.  If Borrower shall be required by law to deduct any such
amounts from or in respect of any sum payable hereunder to any Lender or
Administrative Agent, then, except as provided in Subsection 1.13(B), the sum
payable hereunder shall be increased as may be necessary so that, after making
all required deductions, such Lender or Administrative Agent receives an amount
equal to the sum it would have received had no such deductions been made.

           (B)  Foreign Lenders.  Each Lender organized under the laws of a
                ---------------
jurisdiction outside the United States (a "Foreign Lender") as to which payments
to be made under this Agreement or under the Notes are exempt from United States
withholding tax or are subject to United States withholding tax at a reduced
rate under an applicable statute or tax treaty shall provide to Borrower and
Administrative Agent (1) a properly completed and executed Internal Revenue
Service Form 4224 or Form 1001 or other applicable form, certificate or document
prescribed by the Internal Revenue Service of the United States certifying as to
such Foreign Lender's entitlement to such exemption or reduced rate of
withholding with respect to payments to be made to such Foreign Lender under
this Agreement and under the Notes (a "Certificate of Exemption") or (2) a
letter from any such Foreign Lender stating that it is not entitled to any such
exemption or reduced rate of withholding (a "Letter of Non-Exemption").  Prior
to becoming a Lender under this Agreement and within fifteen (15) days after a
reasonable written request of Borrower or Administrative Agent from time to time
thereafter, each Foreign Lender that becomes

                                       15
<PAGE>

a Lender under this Agreement shall provide a Certificate of Exemption or a
Letter of Non-Exemption to Borrower and Administrative Agent.

           If a Foreign Lender is entitled to an exemption with respect to
payments to be made to such Foreign Lender under this Agreement (or to a reduced
rate of withholding) and does not provide a Certificate of Exemption to Borrower
and Administrative Agent within the time periods set forth in the preceding
paragraph, Borrower shall withhold taxes from payments to such Foreign Lender at
the applicable statutory rates and Borrower shall not be required to pay any
additional amounts as a result of such withholding, provided that all such
                                                    --------
withholding shall cease or be reduced, as appropriate, upon delivery by such
Foreign Lender of a Certificate of Exemption to Borrower and Administrative
Agent.

     1.14  Changes in Tax Laws.  In the event that, subsequent to the Closing
           -------------------
Date, (i) any changes in any existing law, regulation, treaty or directive or in
the interpretation or application thereof, (ii) any new law, regulation, treaty
or directive enacted or any interpretation or application thereof, or (iii)
compliance by Administrative Agent or any Lender with any request or directive
(whether or not having the force of law) from any Governmental Authority:

                (i)   does or shall subject Administrative Agent or any Lender
to any tax of any kind whatsoever with respect to this Agreement, the other Loan
Documents or any Loans made hereunder, or change the basis of taxation of
payments to Administrative Agent or such Lender of principal, fees, interest or
any other amount payable hereunder (except for net income taxes, or franchise
taxes imposed in lieu of net income taxes, imposed generally by federal, state
or local taxing authorities with respect to interest or commitment or other fees
payable hereunder or changes in the rate of tax on the overall net income of
Administrative Agent or such Lender); or

                (ii)  does or shall impose on Administrative Agent or any Lender
any other condition or increased cost in connection with the transactions
contemplated hereby or participations herein;

and the result of any of the foregoing is to increase the cost to Administrative
Agent or any such Lender of making or continuing any Loan, or to reduce any
amount receivable hereunder, then, in any such case, Borrower shall promptly pay
to Administrative Agent or such Lender, upon its demand, any additional amounts
necessary to compensate Administrative Agent or such Lender, on an after-tax
basis, for such additional cost or reduced amount receivable, as determined by
Administrative Agent or such Lender with respect to this Agreement or the other
Loan Documents.  If Administrative Agent or such Lender becomes entitled to
claim any additional amounts pursuant to this Subsection 1.14, it shall promptly
notify Borrower of the event by reason of which Administrative Agent or such
Lender has become so entitled.  A certificate as to any additional amounts
payable pursuant to the foregoing sentence submitted by Administrative Agent

                                       16
<PAGE>

or such Lender to Borrower and Administrative Agent shall, absent manifest
error, be final, conclusive and binding for all purposes. There is no limitation
on the number of times such a certificate may be submitted.

     1.15  Term of This Agreement.  All of the Obligations shall become due
           ----------------------
and payable as otherwise set forth herein, but in any event, all of the
remaining Obligations shall become due and payable on the date set forth in
clause (iii) of the definition of the term "Expiration Date."  This Agreement
shall remain in effect through and including, and shall terminate immediately
after, the date on which all Obligations shall have been indefeasibly and
irrevocably paid and satisfied in full.

                                   SECTION 2

                             AFFIRMATIVE COVENANTS

     Borrower covenants and agrees that so long as this Agreement is in effect
and until payment in full of all Obligations, unless Requisite Lenders shall
otherwise give their prior written consent, Borrower shall perform and comply,
and shall cause its Restricted Subsidiaries to perform and comply, with all
covenants in this Section 2.

     2.1   Compliance With Laws.  Borrower will (i) comply with and will cause
           --------------------
its Restricted Subsidiaries to comply with the requirements of all Applicable
Laws (including laws, rules, regulations and orders relating to taxes, employer
and employee contributions, securities, employee retirement and welfare
benefits, environmental protection matters and employee health and safety) as
now in effect and which may be imposed in the future in all jurisdictions in
which Borrower or any of its Restricted Subsidiaries are now or hereafter doing
business, other than those laws, rules, regulations and orders the noncompliance
with which could not reasonably be expected to have, either individually or in
the aggregate, a Material Adverse Effect, and (ii) obtain and maintain and will
cause each of its Restricted Subsidiaries to obtain and maintain all licenses,
qualifications and permits (including the Licenses) now held or hereafter
required to be held by Borrower or any of its Restricted Subsidiaries, the loss,
suspension or revocation of which or which the failure to obtain or renew could
reasonably be expected to have a Material Adverse Effect.  This Subsection 2.1
shall not preclude Borrower or any of its Restricted Subsidiaries from
contesting any taxes or other payments, if they are being diligently contested
in good faith and if adequate reserves therefor are maintained in conformity
with GAAP.

     2.2   Maintenance of Books and Records; Properties; Insurance.  Borrower
           -------------------------------------------------------
will and will cause each of its Subsidiaries to keep adequate records and books
of account, in which complete entries will be made in accordance with GAAP
consistently applied, reflecting all financial transactions.  Borrower will and
will cause each of its Restricted Subsidiaries to maintain or cause to be
maintained in good repair, working order and condition all material properties
used in the

                                       17
<PAGE>

business of the Borrower and its Restricted Subsidiaries, and will make or cause
to be made all appropriate repairs, renewals and replacements thereof. Borrower
will and will cause each of its Restricted Subsidiaries to maintain or cause to
be maintained, with financially sound and reputable insurers, public liability,
property loss and damage and business interruption insurance with respect to its
business and properties and the business and properties of Borrower and its
Restricted Subsidiaries against loss and damage of the kinds customarily carried
or maintained by corporations of established reputation engaged in the cellular
telephone and wireless communications industry and in amounts acceptable to
Administrative Agent and will deliver evidence thereof to Administrative Agent.
If any part of the Collateral lies within a "special flood hazard area" as
defined and specified by the Federal Emergency Management Agency (or other
appropriate Governmental Authority) pursuant to the Flood Disaster Protection
Act of 1973, as amended (the "FDPA"), and Administrative Agent or any Lender
determines that flood insurance coverage is required to be obtained for such
Collateral in order for Administrative Agent or such Lender to comply with the
FDPA, Borrower shall or shall cause the applicable Subsidiary Guarantor to,
obtain and maintain such flood insurance policies as Administrative Agent or
such Lender reasonably requests so that Administrative Agent or such Lender
shall be deemed in compliance with the FDPA and shall deliver evidence thereof
to Administrative Agent or such Lender. Such policies of flood insurance shall
be in form satisfactory to Administrative Agent or such Lender and shall be in
an amount of at least the lessor of the value of such Collateral constituting
buildings, structures or personal property located within the "special flood
hazard area" or the maximum limit of coverage available under Applicable Law.
Borrower will, and will cause each of the Subsidiary Guarantors to, cause
Administrative Agent, for the benefit of Administrative Agent and Lenders,
pursuant to endorsements and assignments in form and substance reasonably
satisfactory to Administrative Agent to be named, (i) as a lender loss payee in
the case of casualty insurance, (ii) as an additional insured in the case of all
liability insurance, (iii) as assignee in the case of all business interruption
insurance and (iv) as an additional insured in the case of all flood insurance.
All insurance policies required hereunder shall (i) include effective waivers by
the insurer of subrogation, (ii) provide that all insurance proceeds shall be
adjusted with and paid to Administrative Agent and (iii) be non-cancelable as to
Administrative Agent except upon thirty (30) days prior written notice given by
the insurer to Administrative Agent.

     2.3  Inspection; Lender Meeting.  Borrower will and will cause each of
          --------------------------
its Subsidiaries to permit any authorized representatives of any Lender (i) to
visit and inspect any of the properties of Borrower and its Subsidiaries,
including their financial and accounting records, and to make copies and take
extracts therefrom, (ii) for the purpose of determining or monitoring the value
of the collateral, to obtain environmental audits or assessments (including soil
samples) by an independent engineer of any Collateral constituting real estate
or interests in real estate, and (iii) to discuss its and their affairs,
finances and business with its and their officers, employees and certified
public accountants, at such reasonable times during normal business hours and as
often as may be reasonably requested.  Without in any way limiting the
foregoing, Borrower will and

                                       18
<PAGE>

will cause each of its Subsidiaries to participate and will cause its and their
key management personnel to participate in a meeting with Administrative Agent
and Lenders at least once during each year, which meeting shall be held at such
time and such place as may be reasonably requested by Administrative Agent.

     2.4  Legal Existence, Etc. Except as otherwise permitted by Subsection
          ---------------------
3.6, Borrower will and will cause each of its Restricted Subsidiaries to at all
times preserve and keep in full force and effect its legal existence and good
standing and all rights and franchises material to its or their business.

     2.5  Use of Proceeds.  Borrower will use the proceeds of the Loans solely
          ---------------
for the purposes described in the recital paragraphs to this Agreement.  No part
of any Loan will be used to purchase any margin securities or otherwise in
violation of the regulations of the Federal Reserve System.

     2.6  Further Assurances; Notices of Acquisition of Real Property.
          -----------------------------------------------------------
Borrower will and will cause each of the Subsidiary Guarantors, from time to
time, do, execute and deliver all such additional and further acts, documents
and instruments as Administrative Agent or any Lender reasonably requests to
consummate the transactions  contemplated hereby and to vest completely in and
assure Administrative Agent and Lenders of their respective rights under this
Agreement and the other Loan Documents, including such financing statements,
documents, security agreements and reports to evidence, perfect or otherwise
implement the security for repayment of the Obligations contemplated by the Loan
Documents.  Borrower will notify Administrative Agent in writing prior to the
acquisition (including by way of lease) by Borrower or any Subsidiary Guarantor
of any real property or any interest therein (and the cost thereof or annual
rentals with respect thereto) and will, prior to any such acquisition, execute
and deliver all such additional documents and instruments as Administrative
Agent may require pursuant to this Section 2.6 (including mortgages, title
insurance policies, environmental audits, surveys and legal opinions).

     2.7  CoBank Patronage Capital.  So long as CoBank is a Lender hereunder,
          ------------------------
Borrower will acquire non-voting participation certificates in CoBank in such
amounts and at such times as CoBank may require in accordance with CoBank's
Bylaws and Capital Plan (as each may be amended from time to time), except that
the maximum amount of participation certificates that Borrower may be required
to purchase in CoBank in connection with the Loans may not exceed the maximum
amount permitted by the Bylaws at the time this Agreement is entered into.  The
rights and obligations of the parties with respect to such participation
certificates and any distributions made on account thereof or on account of
Borrower's patronage with CoBank shall be governed by CoBank's Bylaws.  Borrower
hereby consents and agrees that the amount of any distributions with respect to
its patronage with CoBank that are made in qualified written notices of
allocation (as defined in 26 U.S.C. (S) 1388) and that are received by Borrower
from CoBank, will be taken into account by Borrower at the stated dollar amounts
whether the distribution is

                                       19
<PAGE>

evidenced by a participation certificate or other form of written notice that
such distribution has been made and recorded in the name of Borrower on the
records of CoBank. CoBank's Pro Rata Share of the Loans and other Obligations
due to CoBank shall be secured by a statutory first lien on all equity which
Borrower may now own or hereafter acquire in CoBank. Such equity shall not,
however, constitute security for the Obligations due to any other Lender. CoBank
shall not be obligated to set off or otherwise apply such equities to Borrower's
obligations to CoBank.

     2.8  Collateral Assignments of Material Contracts.  On the Closing Date,
          --------------------------------------------

time.

assure that Borrower's and each Restricted Subsidiary's computer-based systems
are able to operate and effectively process data including dates prior to, on
and after January 1, 2000 (that is, be "Year 2000 compliant") and to implement
the plan described in Subsection 5.20 in accordance with the timetable described
in Subsection 5.20.  Borrower shall use its best efforts to assure that its and
its Restricted Subsidiaries' material third-party customers, suppliers and
vendors develop and implement programs to be Year 2000 compliant.  At the
request of any Lender, Borrower shall provide such Lender assurance reasonably
satisfactory to such Lender of Borrower's and its Restricted Subsidiaries'
compliance with this Subsection 2.9. Borrower shall advise the Administrative
Agent and the Lenders promptly of any reasonably anticipated Material Adverse
Effect resulting from an inability of Borrower's and its Restricted
Subsidiaries' or any third-party's computer-based systems to be Year 2000
compliant.

     2.10  Enforcement of Sprint Agreements.  Borrower will diligently enforce
           --------------------------------
and will cause its Restricted Subsidiaries diligently to enforce the obligations
of Sprint under the Sprint Agreements.

     5.13  Communications Regulatory Matters.
           ---------------------------------

           (A)  Schedule 5.13(A) sets forth a true and complete list of the
               ----------------
following information for each License issued to Borrower or any of its
Restricted Subsidiaries:  the name of the licensee, the type of service, the
expiration date and the geographic area covered by such License.

           (B)  The Licenses are valid and in full force and effect without
conditions except for such conditions as are generally applicable to holders of
such Licenses. No event has occurred and is continuing which could reasonably be
expected to (i) result in the imposition of a material forfeiture or the
revocation, termination or adverse modification of any such License or (ii)
materially and adversely affect any rights of Borrower or any of its Restricted
Subsidiaries thereunder. Borrower has no reason to believe and has no knowledge
that any Licenses will not be renewed in the ordinary course, except that all of
the Licenses are subject to revocation if LA Unwired fails to meet required
build-out requirements due to obligations to Sprint pursuant to the Sprint
Agreements to use Sprint spectrum. Neither Borrower nor any of its Restricted
Subsidiaries is a party to any investigation, notice of violation, order or
complaint issued by or before the FCC, and there are no proceedings pending by
or before the FCC which could in any manner threaten or adversely affect the
validity of any License.

           (C)  All of the material properties, equipment and systems owned,
leased or managed by Borrower and its Restricted Subsidiaries are, and (to the
best knowledge of Borrower) all such property, equipment and systems to be
acquired or added in connection with any contemplated system expansion or
construction will be, in good repair, working order and condition (reasonable
wear and tear excepted) and are and will be in compliance with all terms and
conditions of the Licenses and all standards or rules imposed by any
Governmental Authority or as imposed under any agreements with telephone
companies and customers.

           (D)  Each of Borrower and its Restricted Subsidiaries has paid all
franchise, license or other fees and charges which have become due pursuant to
any Governmental Approval in respect of its business and has made appropriate
provision as is required by GAAP for any such fees and charges which have
accrued.

     5.14  Perfection and Priority.  The Security Interest is a valid and
           -----------------------
perfected first priority lien, security title or security interest in the
Collateral in favor of Administrative Agent, for the

                                      40
<PAGE>

benefit of itself and Lenders, securing, in accordance with the terms of the
Security Documents, the Obligations, and the Collateral is subject to no Lien
other than permitted pursuant to Subsection 3.2. The Security Interest is
enforceable as security for the Obligations in accordance with its terms.

     5.15  Solvency.  Each of Borrower and its Restricted Subsidiaries: (i)
           --------
owns and will own assets the present fair saleable value of which are (a)
greater than the total amount of liabilities (including contingent liabilities)
of Borrower or such Restricted Subsidiary and (b) greater than the amount that
will be required to pay the probable liabilities of its then existing debts and
liabilities as they become absolute and matured considering all financing
alternatives and potential asset sales reasonably available to Borrower or such
Restricted Subsidiary; (ii) has capital that is not unreasonably small in
relation to its business as presently conducted or after giving effect to any
contemplated transaction; and (iii) does not intend to incur and does not
believe that it will incur debts and liabilities beyond its ability to pay such
debts and liabilities as they become due.

     5.16  Investment Company Act; Public Utility Holding Act.  None of
           --------------------------------------------------
Borrower or any of its Restricted Subsidiaries is an "investment company" as
that term is defined in and is not otherwise subject to regulation under, the
Investment Company Act of 1940, as amended.  None of Borrower or any of its
Restricted Subsidiaries is a "holding company" as that term is defined in, and
is not otherwise subject to regulation under, the Public Utility Holding Company
Act of 1935, as amended.

     5.17  Certain Agreements and Material Contracts.  Schedule 5.17 sets
           -----------------------------------------   -------------
forth a complete and accurate list of all loan agreements, indentures,
guarantees, capital leases and other similar credit or reimbursement agreements
and all Material Contracts of Borrower and its Restricted Subsidiaries.  Each of
Borrower and its Restricted Subsidiaries has performed all of its material
obligations under such agreements and Material Contracts and, to the best
knowledge of Borrower, each other party thereto is in compliance with each such
agreement or Material Contract.  Each such agreement or Material Contract is in
full force and effect in accordance with the terms thereof.  Borrower has made
available a true and complete copy of each such agreement or Material Contract
listed on Schedule 5.17 for inspection by Administrative Agent.
          -------------

     5.18  Capitalization.  The outstanding capital stock or other ownership
           --------------
interests of Borrower and its Subsidiaries is described on Schedule 5.18.  All
                                                           -------------

record as shown on Schedule 5.18.

           -------------------
such title or leasehold interest in and to the real property owned or leased by
it as is necessary or desirable to the conduct of its business and valid and
legal title or leasehold interest in and to all of its personal property,
including those reflected on the balance sheets of Borrower delivered pursuant
to Subsection 5.8, except those which have been disposed of by Borrower
subsequent to such date

                                       41
<PAGE>

which dispositions have been in the ordinary course of business or as otherwise
expressly permitted hereunder. Borrower owns no real property.

     5.20  Year 2000 Compliance.  Each of Borrower and its Restricted
           --------------------
Subsidiaries has (i) initiated a review and assessment of all areas within its
business and operations (including those affected by suppliers, vendors and
customers) that could be adversely affected by the "Year 2000 Problem" (that is,
the risk that computer applications used by such Person (or its suppliers,
vendors and customers) may be unable to recognize and perform properly date-
sensitive functions involving certain dates prior to, on and after December 31,
1999), (ii) developed a plan and timeline for addressing the Year 2000 Problem
on a timely basis, and (iii) to date, implemented that plan in accordance with
the timetable.  Based on the foregoing, each of Borrower and its Restricted
Subsidiaries believes that all computer applications (including those of its
suppliers, vendors and customers) that are material to its and their business
and operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
(that is, be "Year 2000 compliant"), except to the extent that a failure to do
so could not reasonably be expected to have a Material Adverse Effect.

     5.21  Incorporation of Representation and Warranties.  The
           ----------------------------------------------
representations and warranties of Borrower contained in the Preferred Stock
Documents and the Subordinated Debt Documents are true and correct in all
material respects as of each date that the representations and warranties under
this Section 5 are deemed made or remade (and Borrower acknowledges that
Administrative Agent and Lenders are relying on the truth and accuracy of such
representation and warranties in the making of the Loans hereunder).

     6.2  Suspension of Commitments.  Upon the occurrence of any Default or

     6.6  Performance by Administrative Agent.  If Borrower shall fail to

perform any covenant, duty or agreement contained in any of the Loan Documents,
Administrative Agent may perform or attempt to perform such covenant, duty or

periods set forth herein.  In such event, Borrower shall, at the request of
Administrative Agent, promptly pay any amount reasonably expended by
Administrative Agent in such performance or attempted performance to
Administrative Agent, together with interest thereon at the highest rate of
interest in effect upon the occurrence of an Event of Default as specified in
Subsection 1.2(E) from the date of such expenditure until paid.  Notwithstanding
the foregoing, it is expressly agreed that Administrative Agent shall not have
any liability or responsibility for the performance of any obligation of
Borrower under this Agreement or any other Loan Document.

     6.7  Set Off and Sharing of Payments.  In addition to any rights now or
          -------------------------------
hereafter granted under applicable law and not by way of limitation of any such
rights, during the continuance of any Event of Default, each Lender is hereby
authorized by Borrower at any time or from time to time, with reasonably prompt
subsequent notice to Borrower (any prior or contemporaneous notice being hereby
expressly waived) to set off and to appropriate and to apply any and all (A)
balances held by such Lender at any of its offices for the account of Borrower
or any of its Restricted Subsidiaries (regardless of whether such balances are
then due to Borrower or its Restricted Subsidiaries), and (B) except as provided
in Subsection 8.2(J), other property at any time held or owing by such Lender to
or for the credit or for the account of Borrower or any of its Restricted
Subsidiaries, against and on account of any of the Obligations; provided, that
                                                                --------
no Lender shall exercise any such right without the prior written consent of
Administrative Agent.  Any Lender exercising a right to set off shall, to the
extent the amount of any such set off exceeds its Pro Rata Share of the amount
set off, purchase for cash (and the other Lenders shall sell) interests in each
such other Lender's Pro Rata Share of the Obligations as would be necessary to
cause such Lender to share such excess with each other Lender in accordance with
their respective Pro Rata Shares.  Borrower agrees, to the fullest extent
permitted by law, that any Lender may exercise its right to set off with respect
to amounts in excess of its Pro Rata Share of the Obligations and upon doing so
shall deliver such excess to Administrative Agent for the benefit of all Lenders
in accordance with their Pro Rata Shares; provided, that CoBank may exercise its
                                          --------
rights against any equity of CoBank held by Borrower without complying with this
sentence.

     6.8  Application of Payments.  Subsequent to the acceleration of the Loans
          -----------------------
pursuant to Subsection 6.3, all payments received by the Lenders on the

with all such amounts due on the Loans), and then to the principal amount of the
Loans (pro rata among all Loans), in that order.

     6.9  Adjustments.    If any Lender (a "Benefitted Lender") shall at any
          -----------
time receive any payment of all or part of its Loans, or interest thereon in a
greater proportion than any such payment received by any other Lender, if any,
in respect of such other Lender's Loans, or interest thereon, such Benefitted
Lender shall, to the extent permitted by Applicable Law, purchase for cash from
the other Lenders such portion of each such other Lender's Loans as shall be
necessary to cause such Benefitted Lender to share the excess payment or
benefits ratably with each Lender; provided, that if all or any portion of such
                                   --------
excess payment or benefits is thereafter recovered from such Benefitted Lender,
such purchase shall be rescinded, and the purchase price and benefits returned
to the extent of such recovery, but without interest.  Borrower agrees that each
Lender so purchasing a portion of another Lender's Loans may exercise all rights
of payment (including rights of set-off) with respect to such portion as fully
as if such Lender were the direct holder of such portion.  This Subsection 6.9
shall not apply to any action taken by CoBank with respect to equity in it held
by Borrower.

                         ASSIGNMENT AND PARTICIPATION

     8.1  Assignments and Participations in Loans and Notes.  Each Lender
          -------------------------------------------------
(including CoBank) may assign, subject to the terms of a Lender Addition
Agreement, its rights and delegate its obligations under this Agreement to one
or more Persons, provided that (a) such Lender shall first obtain the written
                 --------
consent of each of Administrative Agent and, if no Default or Event of Default
shall have occurred and be continuing, Borrower, which consents shall not be
unreasonably withheld or delayed; (b) the  Pro Rata Share of a Loan Commitment
being assigned shall in no event be less than the lesser of (i) $5,000,000
(which may be aggregated where several Lenders are simultaneously assigning to
the same Person) and (ii) the entire amount of the Pro Rata Share of such Loan
Commitment of the assigning Lender; and (c) upon the consummation of each such
assignment the assigning Lender shall pay Administrative Agent a non-refundable
administrative fee of $2,000; provided, that in connection with an assignment
                              --------
from a Lender to an affiliate of such Lender written consent of Borrower shall
not be required and no administrative fee shall be payable.  From and after the
effective date specified in a duly executed, delivered and accepted Lender
Addition Agreement, which effective date shall be at least five (5)  Business
Days after the execution thereof (unless Administrative Agent shall otherwise
agree), (A) the assignee thereunder shall be a party hereto and, to the extent
that rights and obligations hereunder have been assigned to it pursuant to such
Lender Addition Agreement, shall have the rights and obligations of the
assigning Lender hereunder with respect thereto and (B) the assigning Lender
shall, to the extent that rights and obligations hereunder have been assigned by
it pursuant to such Lender Addition Agreement, relinquish its rights (other than
rights under the provisions of this Agreement and the other Loan Documents
relating to indemnification or payment of fees, costs

                                       54
<PAGE>

and expenses, to the extent such rights relate to the time prior to the
effective date of such Lender Addition Agreement) and be released from its
obligations under this Agreement other than obligations to the extent relating
to the time prior to the effective date of such Lender Addition Agreement (and,
in the case of a Lender Addition Agreement covering all or the remaining portion
of such assigning Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto). The terms and provisions of each
Lender Addition Agreement shall, upon the effectiveness thereof be incorporated
into and made a part of this Agreement, and the covenants, agreements and
obligations of each Lender set forth therein shall be deemed made to and for the
benefit of Administrative Agent and the other parties hereto as if set forth at
length herein. Upon its receipt of a duly completed Lender Addition Agreement
executed by an assigning Lender and an assignee, and Borrower (if required),
together with any Note subject to such assignment and the processing fee
referred to above, Administrative Agent will accept such Lender Addition
Agreement and give notice thereof to Borrower and the other Lenders. In the
event of an assignment pursuant to this Subsection 8.1, Borrower shall, upon
surrender of the assigning Lender's Note, issue a new Note to reflect the
interests of the assigning Lender and the Person to which interests are to be
assigned.

     Each Lender (including Administrative Agent) may sell participations in all
or any part of its Pro Rata Share of each Loan Commitment to one or more
Persons; provided that such Lender shall first obtain the prior written consent
         --------
of Administrative Agent; and provided, further, that such Lender's obligations
                             --------  -------
under this Agreement shall remain unchanged; Borrower, Administrative Agent and
the other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement; all
amounts payable by Borrower hereunder shall be determined as if that Lender had
not sold such participation; and the holder of any such participation shall not
be entitled to require such Lender to take or omit to take any action hereunder
except action directly affecting (i) any reduction, modification or forgiveness
in the principal amount, interest rate or fees payable with respect to any Loan;
(ii) any extension of the Expiration Date, or any change of any date fixed for
any payment of any of the Obligations; and (iii) any consent to the assignment,
delegation or other transfer by Borrower of any of its rights and obligations
under any Loan Document. Borrower hereby acknowledges and agrees that any
participation will give rise to a direct obligation of Borrower to the
participant, and the participant shall for purposes of Subsections 1.11, 1.13,
1.14, 6.7 and 9.1 be considered to be a "Lender."

     Except as otherwise provided in this Subsection 8.1, no Lender shall, as
between Borrower and such Lender, be relieved of any of its obligations
hereunder as a result of any sale, assignment, transfer or negotiation of, or
granting of a participation in, all or any part of the Loans, the Note or other
Obligations owed to such Lender.  Each Lender may furnish any information
concerning Borrower and its Subsidiaries in the possession of that Lender from
time to time to assignees and participants (including prospective assignees and
participants), subject to the provisions of Subsection 9.13.

                                       55
<PAGE>

     Nothing in this Agreement shall be construed to prohibit any Lender from
pledging or assigning all or any portion of its rights and interest hereunder or
under any Note to any Federal Reserve Bank as security for borrowings therefrom;
provided, that no such pledge or assignment shall release a Lender from any of
--------
its obligations hereunder.

     Notwithstanding anything contained in this Agreement to the contrary, so
long as Requisite Lenders shall remain capable of making LIBOR Loans, no Person
shall become a "Lender" hereunder unless such Person shall also be capable of
making LIBOR Loans.

     CoBank reserves the right to assign or sell participations in all or any
part of its Pro Rata Share of each Loan Commitment on a non-patronage basis.

     8.2  Agents.
          ------

          (A)  Appointment.  Each Lender hereby irrevocably appoints and
               -----------
authorizes (i) CoBank, as Administrative Agent, to act as Administrative Agent
hereunder and under any other Loan Document with such powers as are specifically
delegated to Administrative Agent by the terms of this Agreement and any other
Loan Document, together with such other powers as are reasonably incidental
thereto, (ii) The Bank of New York, as Documentation Agent, to act as
Documentation Agent hereunder and under any other Loan Document with such powers
as are specifically delegated to the Documentation Agent by the terms of this
Agreement and any other Loan Document, together with such other powers as are
reasonably incidental thereto, and (iii) First Union Capital Markets Corp., as
Syndication Agent, to act as Syndication Agent hereunder and under any other
Loan Document with such powers as are specifically delegated to the Syndication
Agent by the terms of this Agreement and any other Loan Document, together with
such other powers as are reasonably incidental thereto.  Administrative Agent is
authorized and empowered to amend, modify or waive any provisions of this
Agreement or the other Loan Documents on behalf of Lenders subject to the
requirement that the consent of certain  Lenders be obtained in certain
instances as provided in Subsections 8.3 and 9.2.  CoBank hereby agrees to act
as Administrative Agent on the express conditions contained in this Subsection
8.2.  The provisions of this Subsection 8.2 are solely for the benefit of Agents
and Lenders, and Borrower shall have no rights as a third party beneficiary of
any of the provisions hereof.  In performing its functions and duties under this
Agreement, Agent shall act solely as an agent of Lenders and does not assume and
shall not be deemed to have assumed any obligation toward or relationship of
agency or trust with or for Borrower.  Administrative Agent may execute any of
its duties under this Agreement or any other Loan Document by or through agents
or attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact that it selects with reasonable
care.

          (B)  Nature of Duties.  The duties of Agents and Co-Arrangers shall
               ----------------
be mechanical and administrative in nature.  None of Agents shall have by reason
of this Agreement

                                       56
<PAGE>

a fiduciary relationship in respect of any Lender. Nothing in this Agreement or
any of the Loan Documents, express or implied, is intended to or shall be
construed to impose upon Agents any obligations in respect of this Agreement or
any of the Loan Documents except as expressly set forth herein or therein. Each
Lender expressly acknowledges that none of Administrative Agent or any other
Agent or any Co-Arranger nor any of their respective officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representation
or warranty to it and that no act by Agent or Co-Arranger or any such Person
hereafter taken, including any review of the affairs of Borrower and its
Subsidiaries, shall be deemed to constitute any representation or warranty by
Agent or Co-Arranger to any Lender. Each Lender represents to Agent and Co-
Arranger that (i) it has, independently and without reliance upon Agents, Co-
Arrangers or any other Lender and based on such documents and information as it
has deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, properties, financial and other condition and
creditworthiness of Borrower and its Subsidiaries and made its own decision to
enter into this Agreement and extend credit to Borrower hereunder, and (ii) it
will, independently and without reliance upon Agents, Co-Arrangers or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action hereunder and under the other Loan Documents and
to make such investigation as it deems necessary to inform itself as to the
business, prospects, operations, properties, financial and other condition and
creditworthiness of Borrower and its Subsidiaries. Neither Administrative Agent,
any other Agent nor Co-Arrangers shall have any duty or responsibility, either
initially or on a continuing basis, to provide any Lender with any credit or
other information with respect thereto (other than as expressly required
herein). If Administrative Agent seeks the consent or approval of any Lenders to
the taking or refraining from taking of any action hereunder, then
Administrative Agent shall send notice thereof to each Lender. Administrative
Agent shall promptly notify each Lender any time that Requisite Lenders have
instructed Administrative Agent to act or refrain from acting pursuant hereto.

          (C)  Rights, Exculpation, Etc.    None of Agents or Co-Arrangers nor
               -------------------------
any of their respective officers, directors, employees, agents or attorneys-in-
fact shall be liable to any Lender for any action taken or omitted by them
hereunder or under any of the Loan Documents, or in connection herewith or
therewith, except that each such entity shall be liable with respect to its own
gross negligence or willful misconduct.  Administrative Agent shall not be
liable for any apportionment or distribution of payments made by it in good
faith and if any such apportionment or distribution is subsequently determined
to have been made in error the sole recourse of any Lender to whom payment was
due but not made, shall be to recover from other Lenders any payment in excess
of the amount to which they are determined to be entitled (and such other
Lenders hereby agree to return to such Lender any such erroneous payments
received by them).  In performing its functions and duties hereunder,
Administrative Agent shall exercise the same care which it would in dealing with
loans for its own account, but Administrative Agent shall not be responsible to
any Lender for any recitals, statements, representations or warranties herein or
for the execution, effectiveness, genuineness, validity, enforceability,
collectibility or sufficiency

                                       57
<PAGE>

of this Agreement or any of the Loan Documents or the transactions contemplated
thereby, or for the financial condition of Borrower. Administrative Agent may at
any time request instructions from Lenders with respect to any actions or
approvals which by the terms of this Agreement or of any of the Loan Documents
Administrative Agent is permitted or required to take or to grant, and if such
instructions are promptly requested, Administrative Agent shall be absolutely
entitled to refrain from taking any action or to withhold any approval and shall
not be under any liability whatsoever to any Person for refraining from any
action or withholding any approval under any of the Loan Documents (i) if such
action or omission would, in the reasonable opinion of Administrative Agent,
violate any Applicable Law or any provision of this agreement or any other Loan
Document, or (ii) until it shall have received such instructions from Requisite
Lenders or all of the Lenders, as applicable. Without limiting the foregoing, no
Lender shall have any right of action whatsoever against Administrative Agent as
a result of Administrative Agent acting or refraining from acting under this
Agreement, the Notes, or any of the other Loan Documents in accordance with the
instructions of Requisite Lenders.

          (D)  Reliance.  Administrative Agent shall be entitled to rely, and
               --------
shall be fully protected in relying, upon any written or oral notices,
statements, certificates, orders or other documents or any telephone message or
other communication (including any writing, telex, telecopy or telegram)
believed by it in good faith to be genuine and correct and to have been signed,
sent or made by the proper Person, and with respect to all matters pertaining to
this Agreement or any of the Loan Documents and its duties hereunder or
thereunder, upon advice of counsel selected by it in connection with the
preparation, negotiation, execution, delivery, administration, amendment,
modification, waiver or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement or any of the other Loan Documents.

          (E)  Indemnification.  Lenders will reimburse and indemnify each
               ---------------
Agent and Co-Arranger and their respective officers, directors, employees,
agents, attorneys-in-fact and Affiliates, on demand for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including, attorney's fees and expenses), advances or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against any Agent or Co-Arranger (i) in any way relating to or
arising out of this Agreement or any of the Loan Documents or any action taken
or omitted by such Agent or Co-Arranger under this Agreement or any of the Loan
Documents, and (ii) in connection with the preparation, negotiation, execution,
delivery, administration, amendment, modification, waiver or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement or any of
the other Loan Documents in proportion to each Lender's Pro Rata Share;
provided, that no Lender shall be liable for any portion of such liabilities,
--------
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses, advances or disbursements resulting from such Agent's or Co-Arranger's
gross negligence or willful misconduct.  If any indemnity furnished to
Administrative Agent for any

                                       58
<PAGE>

purpose shall, in the opinion of Administrative Agent, be insufficient or become
impaired, Administrative Agent may call for additional indemnity and cease, or
not commence, to do the acts indemnified against until such additional indemnity
is furnished. The obligations of Lenders under this Subsection 8.2(E) shall
survive the payment in full of the Obligations and the termination of this
Agreement.

          (F)  CoBank Individually.  With respect to its obligations under the
               -------------------
Loan Commitments, the Loans made by it, and the Notes issued to it, CoBank shall
have and may exercise the same rights and powers hereunder and is subject to the
same obligations and liabilities as and to the extent set forth herein for any
other Lender.  The terms "Lenders" or "Requisite Lenders" or any similar terms
shall, unless the context clearly otherwise indicates, include CoBank in its
individual capacity as a Lender or one of the Requisite Lenders.  CoBank may
lend money to, and generally engage in any kind of banking, trust or other
business with, Borrower or any of its Subsidiaries as if it were not acting as
Administrative Agent pursuant hereto.

          (G)  Notice of Default.  Administrative Agent shall not be required
               -----------------
to make any inquiry concerning either the performance or observance of any of
the terms, provisions or conditions of this Agreement or any of the Loan
Documents or the financial condition of Borrower or any of its Subsidiaries, or
the existence or possible existence of any Default or Event of Default.
Administrative Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default unless Administrative Agent shall
have received written notice from Borrower or a Lender referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default." In the event that Administrative Agent receives
such a notice, Administrative Agent will give notice thereof to Lenders as soon
as reasonably practicable; provided, that if any such notice has also been
                           --------
furnished to Lenders, Administrative Agent shall have no obligation to notify
Lenders with respect thereto.  Administrative Agent shall (subject to this
Subsection 8.2) take such action with respect to such Default or Event of
Default as shall reasonably be directed by the Required Lenders; provided,
                                                                 --------
further, that, unless and until Administrative Agent shall have received such
-------
directions, Administrative Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable and in the best interests of
Lenders.

          (H)  Successor Administrative Agent.
               ------------------------------

               (1)  Resignation.  Administrative Agent may resign from the
                    -----------
performance of all its agency functions and duties hereunder at any time by
giving at least thirty (30) Business Days' prior written notice to Borrower and
Lenders.  Such resignation shall take effect upon the acceptance by a successor
Administrative Agent of appointment pursuant to clause (2) below or as otherwise
provided below.

                                       59
<PAGE>

          (2)  Appointment of Successor.  Upon any such notice of resignation
               ------------------------
pursuant to clause (1) above, Requisite Lenders shall, upon receipt, if no Event
of Default or Default shall have occurred and be continuing, of Borrower's prior
consent which shall not be unreasonably withheld, appoint a successor
Administrative Agent from among Lenders.  If a successor Administrative Agent
shall not have been so appointed within the thirty (30) Business Day period,
referred to in clause (1) above, the retiring Administrative Agent, upon notice
to Borrower, shall then appoint a successor Administrative Agent from among
Lenders who shall serve as Administrative Agent until such time, if any, as
Requisite Lenders, upon receipt of Borrower's prior written consent which shall
not be unreasonably withheld, appoint a successor Administrative Agent as
provided above.

          (3)  Successor Administrative Agent.  Upon the acceptance of any
               ------------------------------
appointment as Administrative Agent under the Loan Documents by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations under the Loan Documents.
After any retiring Administrative Agent's resignation as Administrative Agent
under the Loan Documents, the provisions of this Subsection 8.2 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under the Loan Documents.

     (I)  Collateral Matters.
          ------------------

          (1)  Release of Collateral.  Lenders hereby irrevocably authorize
               ---------------------
Administrative Agent, at its option and in its discretion, to release any Lien
granted to or held by Administrative Agent upon any property covered by the
Security Documents (i) upon termination of the Loan Commitments and payment and
satisfaction of all Obligations (other than contingent indemnification
Obligations not then due and payable); (ii) constituting property being sold or
disposed of if Borrower certifies to Administrative Agent that the sale or
disposition is made in compliance with the provisions of this Agreement (and
Administrative Agent may rely in good faith conclusively on any such
certificate, without further inquiry); or (iii) constituting property leased to
Borrower under a lease which has expired or been terminated in a transaction
permitted under this Agreement or is about to expire and which has not been, and
is not intended by Borrower to be, renewed or extended.  In addition,
Administrative Agent, with the consent of Requisite Lenders,  may release or
compromise any Collateral and the proceeds thereof; provided that in any fiscal
                                                    --------
year, the consent of all Lenders shall be required for any release or compromise
of Collateral or the proceeds thereof if (a) such Collateral constitutes a
License or (b) the net book value of such Collateral and proceeds, together with
the net book value of all other Collateral and proceeds released in such fiscal
year, exceeds ten percent (10%) of the net book value of all assets of Borrower
as of the last day of the preceding fiscal year, as determined by Administrative
Agent.

                                       60
<PAGE>

          (2)  Confirmation of Authority; Execution of Releases.  Without in
               ------------------------------------------------
any manner limiting Administrative Agent's authority to act without any specific
or further authorization or consent by Lenders (as set forth in Subsection
8.2(I)(1)), each Lender agrees to confirm in writing, upon request by
Administrative Agent or Borrower, the authority to release any property covered
by the Security Documents conferred upon Administrative Agent under clauses (i)
through (iii) of the first sentence of Subsection 8.2(I)(1). Upon receipt by
Administrative Agent of confirmation from Requisite Lenders, if any, of its
authority to release or compromise any particular item or types of property
covered by the Security Documents, and upon at least ten (10) Business Days
prior written request by Borrower, Administrative Agent shall (and is hereby
irrevocably authorized by Lenders to) execute such documents as may be necessary
to evidence the release or compromise of the Liens granted to Administrative
Agent, for the benefit of Administrative Agent and Lenders, upon such
Collateral, provided that (i) Administrative Agent shall not be required to
            --------
execute any such document on terms which, in Administrative Agent's opinion,
would expose Administrative Agent to liability or create any obligation or
entail any consequence other than the release or compromise of such Liens
without recourse or warranty, and (ii) such release or compromise shall not in
any manner discharge, affect or impair the Obligations or any Liens upon (or
obligations of Borrower, in respect of), all interests retained by Borrower in
the Collateral, including  the proceeds of any sale or other disposition of
Collateral, all of which shall continue to constitute part of the property
covered by the Security Documents.

          (3)  Absence of Duty. Administrative Agent shall have no obligation
               ---------------
whatsoever to any Lender or any other Person to assure that the property covered
by the Security Documents exists or is owned by Borrower or is cared for,
protected or insured or has been encumbered or that the Liens granted to
Administrative Agent have been properly or sufficiently or lawfully created,
perfected, protected or enforced or are entitled to any particular priority, or
to exercise at all or in any particular manner or under any duty of care,
disclosure or fidelity, or to continue exercising, any of the rights,
authorities and powers granted or available to Administrative Agent in this
Agreement or in any other Loan Document, it being understood and agreed that in
respect of the property covered by the Security Documents or any act, omission
or event related thereto, Administrative Agent may act in any manner it may deem
appropriate, in its discretion, given Administrative Agent's own interest in
property covered by the Security Documents as one of the Lenders and that
Administrative Agent shall have no duty or liability whatsoever to any of the
other Lenders, provided that Administrative Agent shall exercise the same care
               --------
which it would in dealing with loans for its own account.

          (J)  Agency for Perfection; Enforcement of Security by Administrative
               ----------------------------------------------------------------
Agent.  Administrative Agent and each Lender hereby appoint each other Lender
-----
as agent for the purpose of perfecting Administrative Agent's security interest
in assets which, in accordance with Article 9 of the Uniform Commercial Code in
                                    ---------
any applicable jurisdiction, can be perfected only by possession.  Should any
Lender (other than Administrative Agent) obtain possession of any such

                                       61
<PAGE>

Collateral, such Lender shall notify Administrative Agent thereof, and, promptly
upon Administrative Agent's request therefor, shall deliver such Collateral to
Administrative Agent or in accordance with Administrative Agent's instructions.
Each Lender agrees that it will not have any right individually to enforce or
seek to enforce any Security Document or to realize upon any collateral security
for the Loans, it being understood and agreed that such rights and remedies may
be exercised only by Administrative Agent.

          (K)  Dissemination of Information.  Administrative Agent will use
               ----------------------------
its best efforts to provide Lenders with any information received by
Administrative Agent from Borrower which is required to be provided to a Lender
hereunder, provided that Administrative Agent shall not be liable to Lenders for
           --------
any failure to do so, except to the extent that such failure is attributable to
Administrative Agent's gross negligence or willful misconduct.

     8.3  Amendments, Consents and Waivers for Certain Actions.
          ----------------------------------------------------

          (A) Except as otherwise provided in this Agreement (including this
Subsection 8.3 and Subsection 9.2), any Lender Addition Agreement or any other
Loan Document, the consent of Requisite Lenders and Borrower will be required to
amend, modify, terminate, or waive any provision of this Agreement or any of the
other Loan Documents.

          (B) In the event Administrative Agent requests the consent of a Lender
and does not receive a written consent or denial thereof within ten (10)
Business Days after such Lender's receipt of such request, then such Lender will
be deemed to have denied the giving of such consent.

     8.4  Disbursement of Funds. Administrative Agent shall advise each
          ---------------------
Lender by telephone or telecopy of the amount of such Lender's Pro Rata Share of
any Loan requested by Borrower no later than 11:00 a.m. (Denver time) on the
Funding Date applicable thereto, and each such Lender shall pay Administrative
Agent such Lender's Pro Rata Share of such requested Loan, in same day funds, by
wire transfer to Administrative Agent's account by no later than 1:00 p.m.
(Denver time) on such Funding Date. If any Lender fails to pay the amount of its
Pro Rata Share forthwith upon Administrative Agent's demand, Administrative
Agent shall promptly notify Borrower, and Administrative Agent shall disburse to
Borrower, by wire transfer of immediately available funds, that portion of such
Loan as to which Administrative Agent has received funds. In such event,
Administrative Agent may, on behalf of any Lender not timely paying
Administrative Agent, disburse funds to Borrower for Loans requested, subject to
the provisions of Subsection 8.5(B). Each such Lender shall reimburse
Administrative Agent on demand for all funds disbursed on its behalf by
Administrative Agent. Nothing in this Subsection 8.4 or elsewhere in this
Agreement or the other Loan Documents, including the provisions of Subsection
8.5, shall be deemed to require Administrative Agent to advance funds on behalf
of any Lender or to relieve any Lender from its obligation to fulfill its
commitments hereunder or to prejudice

                                       62
<PAGE>

any rights that Administrative Agent or Borrower may have against any Lender as
a result of any default by such Lender hereunder.

     8.5  Disbursements of Advances; Payments.
          -----------------------------------

          (A)  Pro Rata Treatment; Application. Upon receipt by
               -------------------------------
Administrative Agent of each payment from Borrower hereunder, other than as
described in the succeeding sentence, Administrative Agent shall credit each
Lender's account with its Pro Rata Share of such payment in accordance with such
Lender's Pro Rata Share and shall wire advice of the amount of such credit to
each Lender. Each payment to Administrative Agent of its fees shall be made in
like manner, but for the account of Administrative Agent.

          (B)  Availability of Lender's Pro Rata Share.
               ---------------------------------------

               (1)  Unless Administrative Agent has been notified by a Lender
prior to a Funding Date of such Lender's intention not to fund its Pro Rata
Share of the Loan amount requested by Borrower, Administrative Agent may assume
that such Lender will make such amount available to Administrative Agent on the
Funding Date. If such amount is not, in fact, made available to Administrative
Agent by such Lender when due, and Administrative Agent disburses funds to
Borrower on behalf of such Lender, Administrative Agent will be entitled to
recover such amount on demand from Borrower, without set-off, counterclaim or
deduction of any kind, with interest thereon at the rate per annum then
applicable to such Loan.

               (2)  Nothing contained in this Subsection 8.5(B) will be deemed
to relieve a Lender of its obligation to fulfill its commitments or to prejudice
any rights Administrative Agent or Borrower may have against such Lender as a
result of any default by such Lender under this Agreement.

          (C)  Return of Payments
               ------------------

               (1)  If Administrative Agent pays an amount to a Lender under
this Agreement in the belief or expectation that a related payment has been or
will be received by Administrative Agent from Borrower and such related payment
is not received by Administrative Agent, then Administrative Agent will be
entitled to recover such amount from such Lender without set-off, counterclaim
or deduction of any kind.

               (2)  If Administrative Agent determines at any time that any
amount received by Administrative Agent under this Agreement must be returned to
Borrower or paid to any other Person pursuant to any solvency law or otherwise,
then, notwithstanding any other term or condition of this Agreement,
Administrative Agent will not be required to distribute any portion thereof to
any Lender. In addition, each Lender will repay to Administrative Agent on
demand

                                       63
<PAGE>

any portion of such amount that Administrative Agent has distributed to
such Lender, together with interest at such rate, if any, as Administrative
Agent is required to pay to Borrower or such other Person, without set-off,
counterclaim or deduction of any kind.

actions, judgments, suits and claims of any kind or nature whatsoever that may
be imposed on, incurred by, or asserted against the Indemnitee as a result of
its being a party to this Agreement; provided, that Borrower shall have no
                                     --------
obligation to an Indemnitee hereunder with respect to liabilities arising from
the gross negligence or willful misconduct of that Indemnitee as determined by a
court of competent jurisdiction. This Subsection 9.1 and all indemnification
provisions contained within any other Loan Document shall survive the
termination of this Agreement.

          ----------------------
amendment, modification, termination or waiver of any provision of this
Agreement, the Notes or any of the other Loan Documents, or consent to any
departure by Borrower therefrom, shall in any event be effective unless the same
shall be in writing and signed by Borrower and Requisite Lenders (or
Administrative Agent, if expressly set forth herein, in any Note or in any other
Loan Document); provided, that except to the extent permitted by any applicable
                --------

required for Administrative Agent to take additional Collateral pursuant to any
Loan Document. No amendment, modification, termination or waiver of any
provision of any Note shall be effective without the written concurrence of the
holder of that Note. No notice to or demand on Borrower in any case shall
entitle Borrower to any other or further notice or demand in similar or other

          -----------------------------------------------------
or delay on the part of Administrative Agent or any Lender to exercise, nor any
partial exercise of, any power, right or privilege hereunder or under any other

                                       65
<PAGE>

     9.5  Marshaling; Payments Set Aside. Neither Administrative Agent nor
          ------------------------------
any Lender shall be under any obligation to marshal any assets in payment of any
or all of the Obligations. To the extent that Borrower makes payment(s) or
Administrative Agent enforces its Liens or Administrative Agent or any Lender
exercises its right of set-off, and such payment(s) or the proceeds of such
enforcement or set-off is subsequently invalidated, declared to be fraudulent or
preferential, set aside, or required to be repaid by anyone, then to the extent
of such recovery, the Obligations or part thereof originally intended to be
satisfied, and all Liens, rights and remedies therefor, shall be revived and
continued in full force and effect as if such payment had not been made or such
enforcement or set-off had not occurred.

     9.6  Severability. The invalidity, illegality, or unenforceability in
          ------------
any jurisdiction of any provision under the Loan Documents shall not affect or
impair the remaining provisions in the Loan Documents.

     9.7  Lenders' Obligations Several; Independent Nature of Lenders' Rights.
          -------------------------------------------------------------------
The obligation of each Lender hereunder is several and not joint and no Lender
shall be responsible for the obligation or commitment of any other Lender
hereunder. In the event that any Lender at any time should fail to make a Loan
as herein provided, the Lenders, or any of them, at their sole option, may make
the Loan that was to have been made by the Lender so failing to make such Loan.
Nothing contained in any Loan Document and no action taken by Administrative
Agent or any Lender pursuant hereto or thereto shall be deemed to constitute
Lenders to be a partnership, an association, a joint venture or any other kind
of entity. The amounts payable at any time hereunder to each Lender shall be a
separate and independent debt.

     9.8  Headings. Section and Subsection headings are included herein for
          --------
convenience of reference only and shall not constitute a part of this Agreement
for any other purposes or be given substantive effect.

     9.9  Applicable Law. THIS AGREEMENT SHALL BE GOVERNED BY AND SHALL BE
          --------------
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
COLORADO, WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES.

     9.10 Successors and Assigns. This Agreement shall be binding upon and inure
          ----------------------
to the benefit of the parties hereto and their respective successors and assigns
except that Borrower may not assign its rights or obligations hereunder without
the written consent of all Lenders.

     9.11 No Fiduciary Relationship. No provision in the Loan Documents and no
          -------------------------
course of dealing between the parties shall be deemed to create any fiduciary
duty owing to Borrower by any Agent, Co-Arranger or Lender.

                                       66
<PAGE>

     9.12  Construction. Each Agent, each Co-Arranger, each Lender and
           ------------
Borrower acknowledge that each of them has had the benefit of legal counsel of
its own choice and has been afforded an opportunity to review the Loan Documents
with its legal counsel and that the Loan Documents shall be constructed as if
jointly drafted by each Agent, each Co-Arranger, each Lender and Borrower.

     9.13  Confidentiality. Agents, Co-Arrangers and Lenders agree to hold
           ---------------
any confidential information that they may receive from Borrower and its
Subsidiaries pursuant to this Agreement in confidence, except for disclosure:
(i) on a confidential basis to legal counsel, independent public accountants and
other professional advisors of Agents, Co-Arrangers or Lenders; (ii) to
regulatory officials having jurisdiction over Agents, Co-Arrangers or Lenders;
(iii) as required by Applicable Law or legal process or (iv) in connection with
any legal proceeding between Agents, Co-Arrangers or Lenders and Borrower
(provided that, in the event Agents, Co-Arrangers or Lenders are so required to
disclose such confidential information pursuant to clauses (iii) or (iv) of this
Subsection 9.13, Agents, Co-Arrangers or Lenders shall promptly notify Borrower,
so that Borrower or any of its Subsidiaries may seek a protective order or other
appropriate remedy); and (v) to another Person in connection with a disposition

One Lakeshore Drive, Suite 1900
Lake Charles, Louisiana 70602-3709
Attention:  Robert Piper, Chief Operating Officer

     Re:  Consent, Waiver and Modification

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein (the "Credit Agreement").  Capitalized terms used and not defined herein
shall have the meanings assigned to them in the Credit Agreement.

     Pursuant to Section 3.7 of the Credit Agreement, Borrower is prohibited
from issuing any capital stock or other equity interests in Borrower, except as
specifically permitted therein.  Pursuant to Section 3.6, Borrower is prohibited
from amending or modifying its articles of incorporation.  Pursuant to Section
1.7(D) of the Credit Agreement, Borrower is required to repay any Loans in the
amount of fifty percent (50%) of the net proceeds from the issuance of any
ownership interests in Borrower (and, pursuant to Section 1.6(B) of the Credit
Agreement, the Revolving Loan Commitment is correspondingly to be reduced by the
amount of such required repayment, whether or not any Loans are then outstanding
and available to be repaid).  Borrower has requested Requisite Lenders to
consent to its issuance of Senior Redeemable Convertible Preferred Stock, Series
B, with an aggregate purchase price of $5,000,000 (the "Series B Preferred
Stock").  A copy of the proposed terms and conditions of the Series B Preferred
Stock is attached hereto (the "Terms and Conditions").  Borrower has requested
the written consent of Requisite Lenders to the issuance of the Series B
Preferred Stock and to amending its articles of incorporation to reflect the
terms of the Series B Preferred Stock and the written waiver of Requisite
Lenders to the provisions of Section 1.6(B) that would reduce the Revolving Loan
Commitment by fifty percent (50%) of the net proceeds of the Series B Preferred
Stock.  In reliance on the representations and warranties provided by Borrower
to Agents in connection with the request for such consents and waiver, Requisite
Lenders hereby consent to the issuance of the Series B Preferred Stock and to
amending its articles of incorporation to reflect the terms of the Series B
Preferred Stock and hereby waive the provisions of Section 1.6(B) that would
reduce the Revolving Loan Commitment by fifty percent (50%) of the net proceeds
of the Series B Preferred Stock, provided that the Series B Preferred Stock is
issued on

substantially the terms and conditions set forth in the attached Terms and
Conditions. For all purposes of the Credit Agreement, except Sections 6.1(V) and
7.1(F)(6), the definition of the term "Preferred Stock" is hereby modified to
include the Series B Preferred Stock, the definition of the term "Warrants" is
hereby modified to include any warrants to be issued by Borrower pursuant to the
securities purchase agreement or similar agreement entered into between Borrower
and the purchaser of the Series B Preferred Stock and the related documentation
executed in connection therewith, all such documentation in form and substance
satisfactory to Agents (collectively, the "Series B Preferred Stock Documents"),
and the definition of the term "Preferred Stock Documents" is hereby modified to
include the Series B Preferred Stock Documents.

     In addition, an Event of Default occurred under Section 6.1(X) of the
Credit Agreement when Command Connect failed, by December 13, 1999, to validly
transfer all of its PCS licenses to LA Unwired.  Borrower has represented that
all necessary FCC approvals have been obtained for such transfer, and that the
transfers were consummated on December 15 and December 17.  In reliance on such
representation of Borrower, Requisite Lenders hereby modify Section 6.1(X) to
extend the date until December 17, 1999 by which such license transfers must
occur.  This extension is conditioned upon Borrower delivering, on or before
January 27, 2000, evidence of such transfers satisfactory to Agents, including
without limitation, a favorable opinion of FCC counsel as to the effectiveness
of such transfers, all in form and substance satisfactory to Agents.  Failure by
Borrower to deliver such evidence by January 27, 2000 shall constitute an Event
of Default.  Without limiting the foregoing, Lenders expressly reserve any and
all rights they may have under the Credit Agreement or any other Loan Document
arising out of or in connection with any other Default or Event of Default.

     Except as expressly modified by this letter agreement, the terms and
provisions of the Credit Agreement and the other Loan Documents are hereby
ratified and confirmed and shall continue in full force and effect.  Without
limiting any conditions to effectiveness set forth above, the consent, waiver

Attention:  Robert Piper, Chief Operating Officer

     Re:  Consent

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein, as amended by that certain letter dated December 29, 1999 (the "Credit
Agreement").  Capitalized terms used and not defined herein shall have the
meanings assigned to them in the Credit Agreement.

     Pursuant to Section 3.2 of the Credit Agreement, Borrower is prohibited
from creating any Lien on any of its property, except Permitted Encumbrances.
Permitted Encumbrances expressly permit Liens granted in connection with
Indebtedness incurred by Borrower for the purpose of financing the acquisition,
construction and renovation of a headquarters building in a principal amount not
to exceed $7,000,000, provided such Lien attaches only to the building and
associated interests in real estate acquired or renovated with such
Indebtedness.  Borrower has requested Requisite Lenders to consent to its
purchase of its headquarters building, the related financing and Lien granted by
Borrower in connection with both the purchase and the related financing.  Copies
of drafts of the documents effecting such purchase, financing and Liens have
been provided to Agents, which documents are listed on Exhibit A (the "Draft
                                                       ---------
Documents").  Such documents include both a Lien on a $100,000 Certificate of
Deposit to secure certain lease assumption obligations, and a Lien on certain
contract rights associated with the headquarters building to secure the
acquisition and renovation financing.  Neither of such Liens constituted
Permitted Encumbrances.  In reliance on the representations and warranties
provided by Borrower to Agents in connection with the request for such consent,
Requisite Lenders hereby consent to the acquisition by Borrower of its
headquarters building, the related financing and associated Liens, provided that
(i) such transactions are consummated and such Liens are granted on
substantially the terms and conditions set forth in the Draft Documents and (ii)
the principal amount of the Indebtedness secured by such Liens does not exceed
$7,000,000.

conditions to effectiveness set forth above, the consent provided herein is to

Attention:  Robert Piper, Chief Operating Officer

     Re:  Consent, Waiver, Release and Approval

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein, as amended by that certain letter dated December 29, 1999 (the "Credit
Agreement").  Capitalized terms used and not defined herein shall have the
meanings assigned to them in the Credit Agreement.

     Unwired Telecom, a Subsidiary Guarantor, is a partner in Meretel
Communications Limited Partnership ("Meretel"), along with EATELCORP, Inc.
("EATEL"), XIT Leasing Inc. ("XIT"), and Fort Bend Telephone Company ("Fort
Bend"; Unwired Telecom, EATEL, XIT and Fort Bend, collectively, the "Meretel
Partners").  Unwired Telecom and the other Meretel Partners have agreed to
restructure Meretel and to separate off certain of its assets into Texas Unwired
(the "Meretel Restructuring"), all pursuant to the terms of the Omnibus
Agreement, dated as of September 7, 1999, among Meretel, the Meretel Partners
and certain related entities, as amended by the First Amendment to Omnibus
Agreement, dated as of January 1, 2000, among the same parties (as so amended,
and along with all exhibits and schedules thereto, the "Omnibus Agreement").
Among other actions, the Meretel Restructuring will involve:

(i)   the distribution by Meretel to Unwired Telecom of an undivided interest
      (the "Undivided Interest") in Meretel's existing assets and customers and
      certain liabilities relating or allocated to the Beaumont-Port Arthur and
      the Lufkin-Nacogdoches, Texas BTAs;

(ii)  the distribution of the Undivided Interest by Unwired Telecom to Borrower;

(iii) the contribution of the Undivided Interest by Borrower into LA Unwired,
      another Subsidiary Guarantor;
<PAGE>

January 31, 2000
Page 2

(iv)   the contribution of the Undivided Interest by LA Unwired into Texas
       Unwired;

(v)    the payment in the amount of $5,527,008 plus accrued interest from
       January 1, 2000 at 8.0% (applied against a portion of that amount equal
       to $4,027,008) by Meretel to Unwired Telecom relating to the transfer,
       effective August 1, 1998, by Unwired Telecom to Meretel of certain PCS
       customers and related assets, such payment to be made either in cash
       and/or as an increase in Unwired Telecom's capital account in Meretel;

(vi)   the reduction in Unwired Telecom's percentage partnership interest in
       Meretel (and a corresponding reduction in Unwired Telecom's guarantee of
       Meretel's senior indebtedness);

(vii)  the amendment of LA Unwired's Sprint PCS Management Agreement to remove
       the Biloxi-Gulfport, Mississippi BTA from LA Unwired's Service Area;

(viii) the reduction and modification of the management and other services
       provided by Unwired Telecom to Meretel pursuant to the November 12, 1999
       letter from Unwired Telecom to Meretel, a copy of which is attached (the
       "Services Agreement"); and

(ix)   an intercompany loan by LA Unwired to Texas Unwired to refinance certain
       indebtedness of Meretel assumed by Texas Unwired, such intercompany loan
       to be evidenced by the Loan Agreement, dated as of January 1, 2000,
       between Texas Unwired and LA Unwired, and certain related loan, guarantee
       and security documents (collectively, the "Texas Unwired Loan
       Documents"), and collaterally assigned to Administrative Agent, for its
       benefit and the benefit of Lenders, pursuant to the Collateral Assignment
       of Loan Documents, dated as of January 1, 2000, made by LA Unwired in
       favor of Administrative Agent, for its benefit and the benefit of Lenders
       (the "Collateral Assignment").

       Borrower has requested Lenders to (a) consent to the Meretel
Restructuring, as described above and in further detail in the Omnibus
Agreement, (b) waive the Revolving Loan Commitment reduction requirements, if
any, that may arise in connection with the payment by Meretel to Unwired Telecom
for the August, 1998 transfer of PCS customers and related assets, (c) release
any liens in favor of Lenders that may attach to the Undivided Interest while
the Undivided Interest is held by Unwired Telecom, Borrower or LA Unwired prior
to the contribution of the Undivided Interest into Texas Unwired, and (d)
approve the Texas Unwired Loan Documents.  In reliance on the representation and
warranties provided by Borrower to Agents in connection with its request, and
pursuant to the Credit Agreement and the other Loan Documents, including,
without

limitation, Sections 1.6(B), 1.7(G), 3.1(C)(4), 3.3(C), 3.3(E), 3.5, 3.8, 3.9,
3.11 and 3.14 of the Credit Agreement, Lenders hereby grant such consent,
waiver, release and approval provided that:

A.  the Meretel Restructuring is consummated on the terms and conditions set
    forth in the Omnibus Agreement, with only such variations as are disclosed
    to, and consented to by, Agents;

B.  the amounts advanced under the Texas Unwired Loan Documents do not exceed
    the amounts permitted under Section 3.1(C)(4) of the Credit Agreement;

C.  Administrative Agent receives an executed original of the Collateral
    Assignment and the Texas Unwired Loan Documents, accompanied by an opinion
    satisfactory to Agents as to the enforceability of such agreements and
    related Liens and addressing such other matters as Agents shall require;

D.  Administrative Agent receives evidence satisfactory to it that none of
    Unwired Telecom, Borrower or LA Unwired remain liable for any liabilities
    assumed from Meretel, and that Texas Unwired expressly assumes all such
    liabilities; and

E.  Agents shall receive such other agreements, documents, certificates and
    opinions as they shall request.

      In addition, because of the completion of the Meretel Restructuring after
December 31, 1999, LA Unwired and Texas Unwired do not comply with the
requirements of Section 4.2 of the Credit Agreement as of December 31, 1999.
Had the Meretel Restructuring been completed by December 31, 1999, Borrower
represents that LA Unwired and Texas Unwired would have complied with the
requirements of such Section 4.2.  Based upon such representation, Lenders
hereby agree to waive the requirements of such Section 4.2 for the December 31,
1999 measurement date.

      Except for any variations expressly consented to in this letter agreement
in connection with the above-described transactions, the terms and provisions of
the Credit Agreement and the other Loan Documents are hereby ratified and
confirmed and shall continue in full force and effect.  Without limiting any
conditions to effectiveness set forth above, the consent provided herein is to
be effective only upon receipt by the Administrative Agent of an execution
counterpart of this letter agreement signed by Borrower, Lenders and Guarantors,
and is conditioned upon the correctness of all representations and warranties
made by Borrower.  This letter agreement shall be governed by, construed and
enforced in accordance with all provisions of the Credit Agreement.

Fort Bend Communication Companies, Inc. ("FBCC") in favor of LA Unwired (the

     Except as expressly provided by this letter agreement, the terms and
provisions of the Credit Agreement, the FBCC Guaranty and the other Loan

     Re:  Consent, Waiver, Modification, Release and Termination

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein, as amended by that certain letter agreement dated December 29, 1999 (as
so amended, the "Credit Agreement").  Capitalized terms used and not defined
herein shall have the meanings assigned to them in the Credit Agreement.

                            Initial Public Offering
                            -----------------------

     Pursuant to Subsection 3.7 of the Credit Agreement, Borrower is prohibited
from issuing any capital stock or other equity interests in Borrower, except as
specifically permitted therein.  Pursuant to Subsection 3.6, Borrower is
prohibited from amending or modifying its articles of incorporation.  Pursuant
to Subsection 1.7(D) of the Credit Agreement, Borrower is required to repay any
Loans in the amount of fifty percent (50%) of the Net Proceeds from the issuance
of any ownership interests in Borrower (and, pursuant to Subsection 1.6(B) of
the Credit Agreement, the Revolving Loan Commitment is correspondingly to be
reduced by the amount of such required repayment, whether or not any Loans are
then outstanding and available to be repaid). Borrower has requested Requisite
Lenders to consent to its issuance of common stock to the public pursuant to a
registered offering, in an aggregate number of shares not to exceed 15% of the
ownership interest of Borrower (based upon rights to receive payments upon a
distribution of the assets of Borrower) with Net Proceeds from the sale thereof
in an amount at least equal to $100,000,000 (the "Public Stock").  A copy of a
draft S-1 filing, dated March 4, 2000, describing the proposed terms and
conditions of the Public Stock and the use of the proceeds thereof (the
"Registration Statement"), has been delivered to Agents.  Borrower has requested
Requisite Lenders to (i) consent to the issuance of the Public Stock and to
Borrower amending its articles of incorporation to reflect the terms of the
Public Stock, and (ii) waive the provisions of Subsection 1.6(B) that otherwise
would reduce the Revolving Loan Commitment by fifty percent (50%) of the Net
Proceeds of the Public Stock.  In reliance (i) on the representations and
warranties provided by Borrower to
<PAGE>

March 10, 2000
Page 2

Agents in connection with the request for such consents and waiver, including
that following completion of the issuance and sale of the Public Stock William
L. Henning, Sr., William L. Henning, Jr., Thomas G. Henning and John A. Henning
(collectively, the "Hennings") will have capital stock constituting at least
fifty-one percent (51%) of the voting control of Borrower (based upon the right
to elect the Board of Directors of Borrower), and (ii) on the description of the
offering of the Public Stock set forth in the Registration Statement, Requisite
Lenders hereby consent to the issuance of the Public Stock and to Borrower
amending its articles of incorporation to reflect the terms of the Public Stock
and hereby waive the provisions of Subsection 1.6(B) that otherwise would reduce
the Revolving Loan Commitment by fifty percent (50%) of the Net Proceeds of the
Public Stock, provided that the Public Stock is issued on substantially the
terms and conditions set forth in the Registration Statement.

     Upon consummation of the issuance and sale of the Public Stock
substantially on the terms and conditions set forth in the Registration
Statement, and the receipt by Borrower of the Net Proceeds therefrom, that
certain Negative Pledge Agreement, dated as of October 1, 1999, made by each of
the Hennings in favor of Administrative Agent, for the benefit of itself and the
other Lenders (the "Negative Pledge Agreement"), shall terminate and the
Hennings shall be released from all their obligations and agreements thereunder
as provided in Section 5 thereof.  The Lenders hereby acknowledge that the
issuance and sale of the Public Stock as provided hereunder shall constitute an
initial public offering approved by Requisite Lenders as provided in clause (ii)
of Section 5 of the Negative Pledge Agreement.

     Subsection 6.1(S) of the Credit Agreement is hereby amended and
supplemented by deleting in its entirety and inserting in lieu thereof the
following:

     "(S) Change in Control.  William L. Henning, Sr., William L. Henning, Jr.,
          -----------------
     Thomas G. Henning and John A. Henning (collectively, the "Hennings"),
     together, cease to beneficially own and control capital stock constituting
     at least fifty-one percent (51%) of the voting control of Borrower (based
     upon the right to elect the Board of Directors of Borrower) and at least
     forty percent (40%) of all ownership interests of Borrower (based upon
     rights to receive payments upon a distribution of the assets of Borrower),
     or LA Unwired ceases to be the Managing Partners of Texas Unwired, or any
     "person" or "group" of related persons (as such terms are defined in the
     Securities Exchange Act of 1934, as amended (the "Exchange Act")), other
     than the Hennings, is or becomes the beneficial owner (as defined in Rules
     13d-3 and 13d-5 under the Exchange Act, except that such person or group
     shall be deemed to have "beneficial ownership" of all shares that any such
     person or group shall have the right to acquire, whether such right is
     exercisable immediately or only after the passage of time), directly or
     indirectly, of a percentage of
<PAGE>

March 10, 2000

     the ownership interests of Borrower (based upon rights to receive payments
     upon a distribution of assets of Borrower) greater than the percentage
     beneficially owned or controlled by the Hennings; or"

                           Asset and Other Transfers:
                           -------------------------

     Pursuant to Subsection 3.8 of the Credit Agreement, Borrower and its
Restricted Subsidiaries are prohibited from selling or otherwise disposing of
any assets or any equity interests in any of its Subsidiaries, except as
specifically permitted therein. Pursuant to Subsection 3.9 of the Credit
Agreement, Borrower and its Restricted Subsidiaries are prohibited from entering
into any transaction with any Affiliate, except as specifically provided
therein.  Pursuant to Subsection 1.7(G) of the Credit Agreement, Borrower is
required to repay Loans in the amount of one hundred percent (100%) of the Net
Proceeds of any Asset Disposition (and, pursuant to Subsection 1.6(B) of the
Credit Agreement, the Revolving Commitment is correspondingly to be reduced by
the amount of such required repayment, whether or not any Loans are then
outstanding and available to be repaid).  Borrower has requested Lenders to
consent to the sale or other disposition:  (i) by Borrower of all of its
membership interests of LEC Unwired, LLC ("LEC Unwired"), (ii) by Unwired
Telecom of all of its membership interests in Command Connect and (iii) by
Unwired Telecom of approximately twenty (20) acres of undeveloped real property
located on Highway 14 in Lake Charles, Louisiana and more particularly described
on Schedule 1 attached hereto (collectively, the "Proposed Transfers").
   ----------
Borrower has also requested that the Lenders consent to one or more of the
Proposed Transfer and proposed transfers by LA Unwired of some or all of its
Licenses not covering the Service Areas (the "License Transfer") being made to
one or more Affiliates of Borrower, in return either for cash or additional
membership interests in LA Unwired, and that Lenders waive the provisions of
Subsection 1.6(B) that otherwise would reduce the Revolving Loan commitment by
one hundred percent (100%) of the Net Proceeds of the Proposed Transfers.  In
reliance on the representations provided by Borrower to Agents in connection
with the request for such consents and waivers, Lenders hereby consent to the
Proposed Transfers, including to the extent any Proposed Transfer or the License
Transfer is made to an Affiliate of Borrower, and waive the provisions of
Subsection 1.6(B) that otherwise would reduce the Revolving Loan Commitment by
one hundred percent (100%) of the Net Proceeds of the Proposed Transfers,
provided (i) the purchase price for the stock of LEC Unwired is at least equal
to the valuation assigned thereto by Chaffe & Associates, Inc., (ii) the
purchase price of the membership interests of Command Connect is at least equal
to the valuation thereof based upon its LMDS licenses being valued at cost,
(iii) the purchase price of the real property described on Schedule 1 is at
                                                           ----------
least equal to the value thereof as shown on Unwired Telecom's books, (iv) the
purchase price in connection with the License Transfer is at least one hundred
twenty-five percent (125%) of the original cost of the transferred Licenses less
any debt assumed in connection therewith, and (v) the purchase price is paid
either in cash or additional membership interests in LA Unwired (if paid in
<PAGE>

March 10, 2000
Page 4

additional membership interests in LA Unwired, the valuation of LA Unwired used
in such calculation to be assigned by Borrower based upon the per PCS POP
valuation used in connection with determining the Public Stock offering price).

     Upon evidence of consummation of any of the Proposed Transfers or License
Transfers, Agents and Lenders agree to execute and deliver, at the expense of
Borrower, any releases, terminations or other documents or instruments necessary
to release any liens or security interests in favor of Agents and Lenders in the
property so disposed.  Upon completion of the disposition by Unwired Telecom of
all of its stock in LEC Unwired, Subsection 3.3(D) of the Credit Agreement shall
be deleted in its entirety.  Upon completion of the disposition by Unwired
Telecom of all of its membership interests in Command Connect, Subsection 3.3(E)
shall be amended by deleting it in its entirety and substituting in lieu thereof
the following:  "Investments by Borrower or any of its Restricted Subsidiaries
in Meretel existing on the Closing Date that shall not, in the aggregate, exceed
$14,500,000."

     Except as expressly provided by this letter agreement, the terms and

                  Substitution of Guarantor for Texas Unwired
                  -------------------------------------------

          LA Unwired has entered into a Loan Agreement, dated as of January 1,
2000, with Texas Unwired (the "Term Unwired Loan Agreement"), pursuant to which
LA Unwired has committed to lend Texas Unwired up to $20,000,000 in aggregate
principal amount (the "Texas Unwired Loan").  In connection with the Texas
Unwired Loan, Fort Bend Communication Companies, Inc. ("FBCC") made a partial
guaranty (the "FBCC Guaranty") in favor of LA Unwired (in the amount of 5% of
all outstanding principal, interest and other obligations due thereunder, but
capped at $1,000,000 with respect to principal).  To secure the FBCC Guaranty
and the Texas Unwired Loan, Fort Bend Telephone Company ("FBTC"), a wholly owned
subsidiary of FBCC and a partner in Texas Unwired, pledged to LA Unwired its
partnership interest in Texas Unwired pursuant to a Partnership Interests Pledge
Agreement, dated as of January 1, 2000 (the "FBTC Pledge Agreement"). Pursuant
to a Collateral Assignment of Loan Documents, dated as of January 1, 2000, LA

including, without limitation, the FBCC Guaranty and the FBTC Pledge Agreement
(the "Collateral Assignment").  Pursuant to Section 3(B) of the Collateral
Assignment, LA Unwired is prohibited from canceling, surrendering or modifying
the FBCC Guaranty or the FBTC Pledge Agreement. Also pursuant to Section 3(B) of
the Collateral Assignment, LA Unwired may not give its consent under the Texas
Unwired Loan to any action by Texas Unwired without obtaining the prior written
consent of Administrative Agent.  Pursuant to Section 3.6 of the Texas Unwired
Loan Agreement, Texas Unwired is prohibited from amending its partnership
agreement.  LA Unwired has requested Lenders to consent to (i) its releasing the
FBCC Guaranty and the FBTC Pledge Agreement, and in substitution thereof receive
a guaranty and pledge from Butler

assets, the wireless assets of FBCC and FBTC; BWI will be spun-off from FBCC in
connection with FBCC's planned merger with a subsidiary of TXU Energy Industries
Company) and (ii) its permitting Texas Unwired to amend its partnership
agreement to substitute BWI for FBTC as a partner in Texas Unwired. In reliance
on the representations and warranties provided by LA Unwired to Agents in
connection with the request for such consent, Lenders hereby consent to LA
Unwired releasing the FBCC Guaranty and the FBTC Pledge Agreement and to
permitting Texas Unwired to amend its Partnership Agreement to admit BWI as a
new partner in substitution of FBTC, subject to the satisfaction, or waiver by
Agents, of the following conditions precedent:

(a)  a guaranty by BWI of the Texas Unwired Loan, on substantively identical
     terms as the FBCC Guaranty except for the revised covenants set forth in
     Schedule 2 hereto (the "BWI Guaranty");
     ----------

(b)  evidence satisfactory to Agents of the transfer by FBTC to BWI of all of
     FBTC's partnership interests in Texas Unwired;

(c)  a pledge by BWI, to secure the BWI Guaranty and the Texas Unwired Loan, of
     all of BWI's partnership interests in Texas Unwired, on substantively
     identical terms as the FBTC Pledge Agreement (the "BWI Pledge Agreement");

(d)  a pledge by the partners of BWI, to secure the BWI Guaranty and the BWI
     Pledge Agreement, of permitted investments (such investments to be as set
     forth on Schedule 3 hereto) with a market value initially equal to at least
              ----------
     135% ($1,350,000) of the maximum principal component of the BWI Guaranty
     (the "Maximum Principal Amount"), such investments to be held in separate
     brokerage accounts pursuant to control agreements satisfactory to Agents,
     and upon such other terms and conditions as Agents shall require,
     including, without limitation, monthly reporting to Administrative Agent on
     the market value of such investments and the mandatory deposit of
     additional permitted investments if their market value at any month end
     drops below 115% ($1,150,000) of the Maximum Principal Amount (such deposit
     to be in the amount necessary to increase the market value to at least 135%
     ($1,350,000) of the Maximum Principal Amount) and at such other times as
     requested by Agents or Requisite Lenders if at such time their market value
     has dropped below 125% ($1,250,000) of the Maximum Principal amount (such
     deposit to be the amount necessary to increase the market value to at least
     125% ($1,250,000) of the Maximum Principal Amount);

(e)  amendment of the Collateral Assignment to include a collateral assignment
     of the BWI Guaranty, the BWI Pledge Agreement and security documents
     described above in paragraph (d); and

FBTC Pledge Agreement.

provisions of the Credit Agreement, the Collateral Assignment and the other Loan
Documents are hereby ratified and confirmed and shall continue in full force and

the Credit Agreement, Borrower is required to repay the Loans in an amount equal
to the Net Proceeds of any Asset Dispositions by LA Unwired and, to the extent
any such amounts are required, pursuant to Subsection 1.8 of the Credit
Agreement, to be applied to the Revolving Loan Facility, the Revolving Loan
Commitment will be reduced permanently by such amount.  Borrower has requested
all Lenders to consent under Subsection 3.8 of the Credit Agreement to, and
waive any repayment requirements or reductions in the Revolving Loan Commitment
associated with, its sale of up to four hundred (400) communications towers and
related property, including related equipment, land, ground leases and leases of
tower space but excluding any wireless phone communications equipment or
licenses or permits necessary to operate such equipment (collectively, the
"Proposed Tower Sales"), to SBA Properties, Inc. or one of more of its
affiliates (collectively, "SBA").  In reliance on the representations and
warranties provided by Borrower and LA Unwired to Agents in connection with the
request for such consent and waiver, and subject to the conditions precedent to
such consent and waiver as set forth below, all Lenders hereby consent to the
Proposed Tower Sales and waive the associated repayment requirement and
reduction of the Revolving Loan Commitment provided for in Subsections 1.6(B)
and 1.7(G) of the Credit Agreement.

     The consent and waiver provided above are subject to the satisfaction, or
waiver by Agents, of the following conditions precedent:

(i)  the Proposed Tower Sales are substantially on the terms and conditions set
     forth in the Asset Purchase Agreement, between LA Unwired and SBA, dated as
     of

      December 18, 2000, provided by Borrower to Agents, with only such
      amendments and deviations thereto as shall be agreed to by Agents (the
      "Asset Purchase Agreement");

(ii)  Administrative Agent, for the benefit of itself and all Lenders, shall
      receive, in form and substance satisfactory to Agents, (a) a first
      priority perfected collateral assignment of LA Unwired's rights under the
      Asset Purchase Agreement and the Antenna Site Agreements (as defined in
      the Asset Purchase Agreement), and (b) a landlord agreement and related
      consents and non-disturbance agreements from SBA and its lenders
      (collectively, the "SBA Consents");

(iii) As soon as commercially practicable after each Closing (as defined in the
      Asset Purchase Agreement), Borrower shall cause collateral assignments (or
      supplements thereto) with respect to the assignment by LA Unwired to
      Administrative Agent, for the benefit of itself and all Lenders, of LA
      Unwired's interest under the Antenna Site Agreements and landlord
      agreements (or supplements thereto), by and among LA Unwired,
      Administrative Agent and SBA, to be recorded in the appropriate real
      property records in the applicable State. Immediately upon the return of
      such recorded documents to Borrower, Borrower shall forward such recorded
      documents to Administrative Agent;

(iv)  The Net Proceeds of the Proposed Tower Sales shall be deposited directly
      into an investment account, and Administrative Agent, for the benefit of
      itself and all Lenders, shall receive a first priority perfected pledge by
      LA Unwired, to secure its Subsidiary Guaranty and the Loans, of all of LA
      Unwired's rights and interests in such investment account, on terms and
      conditions satisfactory to Agents, including, without limitation, that all
      Investments in such investment account shall be in Cash Equivalents and
      amounts in such investment account may not be withdrawn except upon
      receipt by Administrative Agent of a certificate from the chief financial
      officer of Borrower to the effect that such withdrawn amount will be
      applied to the acquisition of additional PCS assets to be owned by
      Borrower or LA Unwired and that are subject to a first priority perfected
      lien in favor of Administrative Agent, for the benefit of itself and all
      Lenders; and

(v)   Agents shall receive such other agreements, documents, certificates and
      opinions as any Agent shall request.

     Borrower agrees to, or to cause LA Unwired to, reinvest the Net Proceeds of
the Proposed Tower Sales, within three hundred sixty (360) days of receipt, in
PCS assets that are subject to a first priority perfected lien in favor of
Administrative Agent, for the benefit of itself and all Lenders.  Any such Net
Proceeds not so reinvested shall be applied by Borrower to repay the Loans and
to reduce the Revolving Loan Commitment in the manner described in Subsections
1.6(B) and 1.7(G).

Attention:  Robert Piper, Chief Operating Officer

     Re:  Consent, Waiver and Amendment

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein, as amended by those certain letter agreements dated December 29, 1999,
March 10, 2000, April 28, 2000 and December 28, 2000 (as so amended, the "Credit
Agreement").  Capitalized terms used and not defined herein shall have the
meanings assigned to them in the Credit Agreement.

        Acquisition of Remaining Partnership Interests in Texas Unwired
        ---------------------------------------------------------------

     Pursuant to Subsection 3.3(C) of the Credit Agreement, Borrower and LA
Unwired are prohibited from making Investments in Texas Unwired which, if in the
form of equity contributions, exceed $4,000,000.  Pursuant to Subsection 3.7 of
the Credit Agreement, Borrower is prohibited from issuing any capital stock or
other equity interests, except as specifically permitted therein.  Pursuant to
Subsections 1.6(B) and 1.7(D) of the Credit Agreement, Borrower is required to
repay the Loans in an amount equal to fifty percent (50%) of the net proceeds of
the issuance of any ownership interests in Borrower and, to the extent any such
amounts are required, pursuant to Subsection 1.8 of the Credit Agreement, to be
applied to the Revolving Loan Facility, the Revolving Loan Commitment will be
reduced permanently by such amount.  Pursuant to Subsection 3.14 of the Credit
Agreement, Borrower is prohibited from permitting either of LA Unwired or Texas
Unwired from amending or terminating any of the Sprint Agreements to which it is
a party.

     Pursuant to a Collateral Assignment of Loan Documents, dated as of January
1, 2000 (the "Collateral Assignment"), LA Unwired collaterally assigned to
Administrative Agent, for the benefit of itself and all Lenders, a revolving
loan made to Texas Unwired in an amount of up to $20,000,000 in aggregate
principal amount (the "Texas Unwired Loan"), and all related documentation,
including, without limitation, partial guaranties (collectively, the "Partner
Guaranties") in favor of LA Unwired made by each of Butler Waddell Interests,
Ltd. ("BWI") and XIT Leasing, Inc. ("XIT") and partnership interest pledge
agreements (collectively, the "Partner Pledge Agreements") in favor of LA
Unwired made by each of BWI and XIT.  Pursuant to Section 3(B) of the Collateral
<PAGE>

February 26, 2001
Page 2

Assignment, LA Unwired is prohibited from (a) canceling, surrendering or
modifying the Partner Guaranties or the Partner Pledge Agreements, or (b)
permitting Texas Unwired to enter into any termination of any of the Sprint
Agreements to which it is a party.

     Borrower has requested Requisite Lenders to consent (1) under Subsections
3.3(C) and 3.7 of the Credit Agreement to, and waive any repayment requirements
or reductions in the Revolving Loan Commitment associated with, Borrower's
acquisition of all of the partnership interests in Texas Unwired not now
currently owned by LA Unwired (the "Acquisition") and Borrower's issuance of
capital stock for the purpose of acquiring all of the partnership interests
currently owned by BWI and XIT (the "Acquisition Issuance"), (2) under
Subsection 3.14 of the Credit Agreement and Section 3(B) of the Collateral
Assignment to each of LA Unwired and Texas Unwired, in the event Texas Unwired
is merged or otherwise consolidated into LA Unwired, amending and terminating,
respectively, the Sprint Agreements to which it is a party to the extent
necessary to reflect such merger or consolidation (collectively, the "Roll-up
Amendments"), and (3)  under Section 3(B) of the Collateral Assignment to LA
Unwired terminating the Partner Guaranties and Partner Pledge Agreements.

     In reliance on the representations and warranties provided by Borrower and
LA Unwired to Agents in connection with the request for such consents and
waiver, Requisite Lenders hereby consent to the Acquisition and the Acquisition
Issuance, and waive the associated repayment requirements and reduction to the
Revolving Loan Commitment provided for in Subsection 1.6(B) and 1.7(G) of the
Credit Agreement, consent to the Roll-up Amendments, and consent to LA Unwired
releasing the Partner Guaranties and the Partner Pledge Agreements.

     The consents and waiver provided above are subject to the satisfaction, or
waiver by Agents, of the following conditions precedent:

(a)  Agents shall receive evidence satisfactory to them of the consummation of
     the Acquisition;

(b)  Administrative Agent, for the benefit of itself and all Lenders, shall
     receive a full guaranty from Texas Unwired of the Loans, on substantively
     identical terms as the Subsidiary Guaranty (the "Texas Unwired Guaranty");

(c)  Administrative Agent, for the benefit of itself and all Lenders, shall
     receive a first priority perfected pledge by Texas Unwired, to secure the
     Texas Unwired Guaranty and the Loans, of all of Texas Unwired's real and
     personal property, on terms and conditions satisfactory to Agents;

(d)  Administrative Agent, for the benefit of itself and all Lenders, shall
     receive a first priority pledge by Borrower, to secure the Loans, of all of
     Borrower's partnership interests in Texas Unwired, on terms and conditions
     satisfactory to Agents;
<PAGE>

February 26, 2001
Page 3

(e)  Agents shall review and approve the Roll-up Amendments; and

(f)  Agents shall receive such other agreements, documents, certificates and
     opinions as any Agent shall request, including evidence that the
     Acquisition, Acquisition Issuance and the satisfaction of the conditions
     precedent set forth above do not violate the Subordinated Debt Documents or
     the Preferred Stock Documents.

     Effective in each case upon the consummation of the Acquisition and the
satisfaction or waiver of the conditions precedent set forth above, Subsection
3.1(C) of the Credit Agreement is hereby amended and restated to read in its
entirety as follows:

          "(4) Indebtedness incurred by Texas Unwired to LA Unwired.";

and clause (iii) of Subsection 3.8 of the Credit Agreement is hereby amended and
restated to read in its entirety as follows:

          "(iii) dispositions among Borrower, LA Unwired, Unwired Telecom and

Unwired's percentage ownership interest in Texas Unwired" is hereby amended and
restated to read in their entirety as follows:

          ownership interest in Texas Unwired";

Attention:  Robert Piper, Chief Operating Officer

     Re:  Waivers and Amendments

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein, as amended by those certain letter agreements dated December 29, 1999,
March 10, 2000, April 28, 2000, December 28, 2000 and February 26, 2001 (as so
amended, the "Credit Agreement").  Capitalized terms used and not defined herein
shall have the meanings assigned to them in the Credit Agreement.

          Acquisition of Remaining Membership Interests in LA Unwired
          -----------------------------------------------------------

     Pursuant to Subsection 3.7 of the Credit Agreement, Borrower is prohibited
from issuing any capital stock or other equity interests, except as specifically
permitted therein.  Pursuant to Subsections 1.6(B) and 1.7(D) of the Credit
Agreement, Borrower is required to repay the Loans in an amount equal to fifty
percent (50%) of the net proceeds of the issuance of any ownership interests in
Borrower and, to the extent any such amounts are required, pursuant to
Subsection 1.8 of the Credit Agreement, to be applied to the Revolving Loan
Facility, the Revolving Loan Commitment will be reduced permanently by such
amount.  Borrower has requested Lenders to waive (1) under Subsection 3.7 of the
Credit Agreement, any breach of the Credit Agreement resulting from Borrower's
issuance of  4,634,842 shares of Class A common stock for the purpose of
acquiring all of the membership interests of LA Unwired then owned by Cameron
Communications Corporation (the "Acquisition Issuance") and (2) any repayment
requirements or reductions in the Revolving Loan Commitment associated with such
issuance under Subsections 1.6(B) and 1.7(D).

     In reliance on the representations and warranties set forth in this letter
agreement or provided by Borrower to Agents in connection with the request for
such waivers and subject to the conditions precedent set forth below, all
Lenders hereby waive any breach resulting from the Acquisition Issuance and
waive the associated repayment requirements and reduction to the Revolving Loan
Commitment provided for in Subsections 1.6(B), 1.7(D) and 1.8 of the Credit
Agreement.
<PAGE>

     The waivers provided above are subject to Administrative Agent receiving
all membership unit certificates of LA Unwired received by Borrower in
connection with the Acquisition Issuance, accompanied by an Irrevocable Transfer
Power, in the form of Exhibit A attached to this letter agreement, executed by
                      ---------
Borrower with respect to such certificates.  Effective upon the date of the
Acquisition Issuance, Schedule 1 to the Membership Interest Pledge Agreement,
dated as of October 1, 1999, between Borrower and Administrative Agent, for the
benefit of itself and all Lenders, is hereby amended and supplemented to read in
its entirety as set forth on Schedule 1 to this letter agreement.
                             ----------

              ---------------------------------------------------

     Effective upon the effective date of this letter agreement, Subsection 10.1
of the Credit Agreement is amended to add the following new definition:

          "`Management Equity Interests' means all options, warrants and other
          rights to acquire capital stock or other ownership interests in
          Borrower, and all capital stock and other ownership interests in
          Borrower issued on account thereof or upon the exercise thereof, that
          were issued and are held by any member of Borrower's or any of its
          Subsidiaries' management pursuant to any management equity
          subscription agreement or stock option agreement in effect on the date
          of the Subordinated Note Indenture."

     Borrower represents and warrants to Lenders that set forth on Exhibit 1 to
this letter agreement is a list of all management equity subscription agreements
and stock option agreement of Borrower or its Subsidiaries.

     Also effective upon the effective date of this letter agreement, Subsection
1.7(D) of the Credit Agreement is hereby amended and restated in its entirety to

          "(D)  Repayments from Equity Issuances.  Immediately upon receipt of
                ---------------------------------
          proceeds from the issuance of any ownership interests in Borrower or
          any rights to purchase any such interest (other than from the issuance
          of Management Equity Interests),  Borrower shall repay the Loans in an
          amount equal to fifty percent (50%) of the amount of (i) such proceeds
          minus (ii) all fees, costs and expenses actually incurred in
          -----
          connection with such equity issuance; provided, however, that Borrower
                                                --------  -------
          shall not be required to repay Loans from proceeds of the issuance of

          permit any of its Restricted Subsidiaries directly or indirectly to
          declare, order, pay, make or set apart any sum for any Restricted
          Junior Payment, including, without limitation, (i) payments with
          respect to any put, redemption or similar rights granted to the
          holders of the Preferred Stock or the Subordinated Notes, (ii)
          payments with respect to any purchase or repurchase options granted to
          the holders of the Subordinated Notes, or (iii) payments of
          "Liquidated Damages" as defined in the Registration Rights Agreement;
          provided, however, that Borrower may (a) make scheduled payments of
          --------  -------
          cash interest on the Subordinated Notes and (b) so long as no Default
          or Event of Default has occurred or is continuing, repurchase, redeem
          or otherwise acquire or retire for value any Management Equity
          Interest if the aggregate price paid for all such repurchased,
          redeemed, acquired or retired Management Equity Interests does not
          exceed $2,000,000 in any fiscal year (any unused amount in any fiscal
          year commencing with the fiscal year ending December 1, 2000 may be
          carried forward to one or more future fiscal years for purposes of
          this exception)."

     Also effective upon the effective date of this letter agreement, Subsection

          "3.7  Restriction on Equity Issuance.  Borrower will not and will not
                ------------------------------
          permit any Restricted Subsidiary directly or indirectly to issue any
          capital stock or other equity interests in Borrower or any Restricted
          Subsidiary (other than the Preferred Stock, the Warrants, capital
          stock issued upon the conversion or exercise of the Preferred Stock or
          Warrants pursuant to the terms of the Preferred Stock Documents,
          Management Equity Interests and equity interests issued and
          outstanding on the date of this Agreement and reflected on Schedule
                                                                     --------
          5.18 hereto)."
          ----
                     Amendment to Articles of Incorporation
                     --------------------------------------

     Pursuant to Subsection 3.6 of the Credit Agreement, Borrower is prohibited

     In reliance on the representations and warranties set forth in this letter
agreement or provided by Borrower to Agents in connection with the request for

                            Amendments to Schedules
                            -----------------------

     Certain of the schedules to the Credit Agreement are hereby amended and
restated by changing them in their entirety to read as provided in Exhibit B
                                                                   ---------

                                    -------

     Except as expressly provided by this letter agreement, the terms and
provisions of the Credit Agreement and the other Loan Documents are hereby

are conditioned upon the correctness of all representations and warranties made
hereunder.  The waivers and amendments contained herein shall not constitute a

respect to) the Credit Agreement or any of the other Loan Documents, any of the

US Unwired Inc.
One Lakeshore Drive, Suite 1900
Lake Charles, Louisiana 70602-3709
Attention:  Robert Piper, Chief Operating Officer

     Re:  Amendments

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of October 1, 1999,
among US Unwired Inc. ("Borrower"), CoBank, ACB, as Administrative Agent and a
Lender, First Union Securities, Inc., formerly known as First Union Capital
Markets Corp., as Syndication Agent and a Co-Arranger, The Bank of New York, as
Documentation Agent and a Lender, BNY Capital Markets, Inc., as a Co-Arranger,
First Union National Bank, as a Lender, and the other Lenders referred to
therein, as amended by those certain letter agreements dated December 29, 1999,
March 10, 2000, April 28, 2000, December 28, 2000, February 26, 2001 and April
24, 2001 (as so amended, the "Credit Agreement").  Capitalized terms used and
not defined herein shall have the meanings assigned to them in the Credit
Agreement.

                Amendment Regarding Maximum Capital Expenditures
                ------------------------------------------------

     Pursuant to a letter agreement dated December 28, 2000, LA Unwired was
permitted to sell up to four hundred (400) communications towers and related
property and was permitted not to apply the Net Proceeds thereof to repay the
Loans or to reduce the Revolving Loan Commitment, provided that LA Unwired
reinvested the Net Proceeds of such sales in additional PCS assets within three
hundred sixty (360) days from receipt thereof.  Reinvestment of the full amount
of such Net Proceeds would cause LA Unwired and Texas Unwired, on a combined
basis, to exceed the maximum cumulative capital expenditures permitted by
Subsection 4.4 of the Credit Agreement.  Borrower has requested Requisite
Lenders to amend Subsection 4.4 of the Credit Agreement to exclude from the
calculation of the permitted maximum cumulative capital expenditures any capital
expenditures for which LA Unwired or Texas Unwired expended any of the Net
Proceeds from such permitted sales (or for which expenditures LA Unwired or
Texas Unwired is reimbursed with such Net Proceeds).  In reliance on the
representations of Borrower and Subsidiary Guarantors set forth in this letter
agreement or provided by Borrower or Subsidiary Guarantors in connection with
this request, Requisite Lenders hereby agree that Subsection 4.4 of the Credit
Agreement shall, as of the effective date of this letter agreement, be amended
to read in its entirety as follows:

     "4.4  Capital Expenditures for LA Unwired and Texas Unwired.  Commencing on
           -----------------------------------------------------
     the Closing Date, Borrower will not, prior to each date set forth below,
     permit LA Unwired and Texas Unwired, on a combined basis, to make capital
     expenditures (excluding capital expenditures for
<PAGE>

September 28, 2001
Page 2

     which LA Unwired or Texas Unwired expended the Net Proceeds (or the
     expenditures for which were reimbursed from the Net Proceeds) of the sale
     of towers permitted pursuant to that letter agreement among Borrower,
     Guarantors, Agents and Lenders, dated as of December 28, 2000) for the
     period commencing on January 1, 1999 and ending on each date set forth
     below in a cumulative amount that exceed, in the aggregate for LA Unwired
     and Texas Unwired, the amount set forth below opposite such date:

                                                Maximum Cumulative
               Date                            Capital Expenditures
               ----                            --------------------
          December 31, 1999                         $ 70,000,000
          December 31, 2000                         $215,000,000
          December 31, 2001                         $260,000,000
          December 31, 2002                         $270,000,000
          December 31, 2003                         $280,000,000"

                    Amendments Regarding Asset Dispositions
                    ---------------------------------------

     Pursuant to Subsection 3.8 of the Credit Agreement, Borrower or its
Restricted Subsidiaries shall not sell or otherwise dispose of assets, subject
to certain exceptions set forth in such Subsection.  Pursuant to Subsection
1.7(G) of the Credit Agreement, Borrower is required to repay the Loans in an
amount equal to the Net Proceeds of any Asset Disposition.  Borrower has
requested that Requisite Lenders amend Subsection 3.8 of the Credit Agreement to
remove clause (v)(a), limiting permitted Assets Dispositions to less than
$250,000 per transaction, and to amend Subsection 1.7(G) of the Credit Agreement
to not require a repayment of the Loans upon a sale or other disposition of an
asset if (i) the disposition complies with clause (v) of Subsection 3.8 of the
Credit Agreement (as herein amended) and (ii) the Net Proceeds of such
disposition are reinvested in other PCS assets within three hundred sixty (360)
days of the receipt of such Net Proceeds.  In reliance on the representations
and warranties of Borrower and Subsidiary Guarantors set forth in this letter
agreement or provided by Borrower or Subsidiary Guarantors in connection with
this request, Requisite Lenders hereby agree that Subsection 3.8 of the Credit
Agreement shall, as of the effective date of this letter agreement, be amended
to read in its entirety as follows:

     "3.8  Disposal of Assets or Subsidiary Stock.  Borrower will not and will
           --------------------------------------
     not permit any of its Restricted Subsidiaries directly or indirectly to:
     convey, sell, lease, sublease, transfer or otherwise dispose of, or grant
     any Person an option to acquire, in one transaction or a series of
     transactions,
<PAGE>

September 28, 2001
Page 3

     any of its property, business or assets, or the capital stock
     of or other equity interests in any of its Subsidiaries, whether now owned
     or hereafter acquired, except for (i) bona fide sales of inventory to
     customers for fair value in the ordinary course of business and
     dispositions of obsolete equipment not used or useful in the business; (ii)
     fair market value sales of Cash Equivalents; (iii) dispositions among
     Borrower, LA Unwired and Unwired Telecom or by Texas Unwired to Borrower,
     LA Unwired or Unwired Telecom; (iv) dispositions by LA Unwired of Licenses
     not covering the Service Areas; and (v) all other Asset Dispositions if all
     of the following conditions are met:  (a) the aggregate market value of
     assets (including such assets but excluding any assets sold pursuant to
     clauses (i) through (v) above inclusive) sold or otherwise disposed of in
     the immediately preceding 12-month period does not exceed $1,000,000 in the
     aggregate for Borrower and its Restricted Subsidiaries; (b) the
     consideration received is at least equal to the fair market value of such
     assets; (c) the sole consideration received is cash; (d) after giving
     effect to the sale or other disposition of such assets, Borrower, on a
     consolidated basis with the Restricted Subsidiaries as set forth in Section
     4, but excluding the Unrestricted Subsidiary, is in compliance on a pro
     forma basis with the covenants set forth in Section 4 recomputed for the
     most recently ended month for which information is available and Borrower
     is in compliance with all other terms and conditions contained in this
     Agreement; and (e) no Default or Event of Default then exists or shall
     result from such sale or other disposition."

, and that Subsection 1.7(G) of the Credit Agreement shall, as of the effective
date of this letter agreement, be amended to read in its entirety as follows:

     "(G)  Repayments from Asset Dispositions.  Immediately upon receipt by
           ----------------------------------
     Borrower or any of its Restricted Subsidiaries of Net Proceeds other than
     insurance proceeds from any Asset Disposition, Borrower shall repay the
     Loans in an amount equal to such Net Proceeds; provided, however, that in
                                                    --------  -------
     the event of an Asset Disposition by Texas Unwired, prepayment pursuant to
     this Subsection 1.7(G) will only be required in proportion to LA Unwired's
     percentage ownership interest in Texas Unwired; provided further, however,
                                                     -------- -------  -------
     that Borrower shall not be required to repay the Loans from Asset
     Dispositions by Texas Unwired to the extent that the proceeds thereof were
     applied to repayments of the indebtedness of Texas Unwired described in
     Subsection 3.1(C)(4) and to the repayment of the Loans pursuant to
     Subsection 1.7(F); and provided further, however, that Borrower shall not
                            -------- -------  -------
     be required to repay the Loans from Asset Dispositions to the extent such
     Asset Dispositions are permitted pursuant to clause (v) of Subsection 3.8
     and the Borrower or its Restricted Subsidiaries reinvests within three
     hundred sixty (360) days of receipt the Net Proceeds of such Asset
     Dispositions in PCS assets used and useful in the business of the

     Borrower or its Restricted Subsidiaries. All such repayments shall be
     applied in accordance with Subsection 1.8."

                                    General
                                    -------

     Except as expressly provided by this letter agreement, the terms and
provisions of the Credit Agreement and the other Loan Documents are hereby
ratified and confirmed and shall continue in full force and effect.  By agreeing
to this letter agreement as acknowledged below, each of Borrower and Subsidiary
Guarantors hereby certifies and warrants to Lenders that after giving effect to
the amendments and waivers effected hereby, each of the representations and
warranties contained in Section 5 of the Credit Agreement and in the other Loan
Documents, after giving effect to the amendments to the schedules provided
above, are true and correct as of the effective date of this letter agreement
with the same effect as though made on such effective date (except to the extent
any such representation or warranty is expressly stated to have been made as of
a specific date, in which case such representations or warranty shall be true
and correct as of such specified date) and that no event has occurred and is
continuing that would constitute a Default or Event of Default.  Without
limiting any conditions to effectiveness set forth above, the waivers provided
and agreed to herein are to be effective only upon receipt by the Administrative
Agent of an execution counterpart of this letter agreement signed by Borrower,
Requisite Lenders and Guarantors and such other documents or agreements signed
by Borrower or any other party as any Agent shall request; and such waivers and
amendments are conditioned upon the correctness of all representations and
warranties made hereunder.  The waivers and amendments contained herein shall
not constitute a course of dealing between Borrower, Guarantors and Lenders, and
shall not constitute a waiver or amendment of any Default or Event of Default,
now or hereafter, arising, or any other provision of the Credit Agreement or the
other Loan Documents.  This letter agreement shall be governed by, construed and
enforced in accordance with all provisions of the Credit Agreement, and may be
executed in multiple counterparts.

     Each of Borrower and Subsidiary Guarantors hereby further acknowledges and
confirms that it does not have any grounds and hereby agrees not to challenge
(or to allege or to pursue any matter, cause or claim arising under or with
respect to) the Credit Agreement or any of the other Loan Documents, any of the
