     SECTION 2. The Credit Agreement shall be amended as follows:

     (a) Subsection 1.1(B) of the Credit Agreement is hereby amended and
restated in its entirely as follows:

     "(B) Revolving Loans. Each Lender, severally and not jointly, agrees to

     Loan A Commitment and the Term Loan B Commitment have been advanced or
     terminated and all conditions precedent set forth in Subsections 7.1, 7.2
     and 7.3 are satisfied or waived as provided herein and ending on the
     Business Day immediately preceding the Revolving Facility Expiration Date,
     its Pro Rata Share of each Revolving Loan; provided that at any one time
     the aggregate principal amount of all Revolving Loans outstanding may not
     exceed the Available Revolving Loan Commitment minus the aggregate Letter
     of Credit Exposure. Within the limits of the Available Revolving Loan
     Commitment minus the aggregate Letter of Credit Exposure and this
     Subsection 1.1(B), amounts borrowed under this Subsection 1.1(B) may be
     prepaid and reborrowed at any time prior to the Revolving Facility
     Expiration Date."

     (b) Subsection 1.4 of the Credit Agreement is hereby amended to insert the
following as Subsection 1.4(E) of the Credit Agreement:

     "(E) Letter of Credit Fees. Borrower agrees to pay the following fees:

          (1) To the Administrative Agent, for the account of each Lender with a
     Revolving Loan Commitment, a letter of credit fee for each calendar quarter
     (or portion thereof) in respect of all Letters of Credit outstanding during
     such quarter, at a per annum rate equal to the LIBOR Margin for the
     Revolving Loan Facility in effect from time to time during such quarter for
     Revolving Loans that are maintained as LIBOR Loans, on such Lender's
     ratable share (based on its Pro Rata Share of the Revolving Loan Commitment
     or, if the Revolving Loan Commitment has expired or terminated, the
     proportion its Letter of Credit Exposure bears to the aggregate Letter of
     Credit Exposure) of the daily average aggregate Stated Amount of such
     Letters of Credit, payable in arrears (i) on the last Business Day of each
     calendar quarter, beginning June 30, 2002, and (ii) on the later of the
     Revolving Facility Expiration Date and the date of termination of the last
     outstanding Letter of Credit.

          (2) To the Issuing Lender for its own account, a facing fee for each
     calendar quarter (or portion thereof) in respect of all Letters of Credit
     issued by the Issuing Lender and outstanding during such quarter, at a per
     annum rate of 0.125% on the daily average aggregate Stated Amount of such
     standby Letters of Credit payable in arrears (A) on the last Business Day
     of each calendar quarter, beginning June 30, 2002, and (B) on the Revolving
     Facility Expiration Date.

          (3) To the Issuing Lender, for its own account, such commissions,
     issuance fees, transfer fees and other fees and charges incurred in
     connection with the issuance and administration of each Letter of Credit as
     are customarily and reasonably charged from time to time by the Issuing
     Lender for the performance of such services in connection

     with similar letters of credit, or as may be otherwise agreed to by the
     Issuing Lender, but without duplication of amounts payable under Subsection
     1.4(E)(2) above."

     (c) Subsection 1.6(D) is hereby amended and restated in its entirety as
follows:

     "(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 plus the aggregate Letter of Credit
     Exposure then outstanding to the amount of the Revolving Loan Commitment as
     so reduced; provided, however, to the extent that the amount of any such
     mandatory repayment is greater than the aggregate principal amount of
     Revolving Loans outstanding immediately prior to the application of such
     prepayment, the excess amount of such repayment shall be retained by the
     Administrative Agent and held in the Cash Collateral Account as cover for
     Letter of Credit Exposure, as more particularly described in Subsection
     1.16(H) and thereupon such cash shall be deemed to reduce the aggregate
     Letter of Credit Exposure by an equivalent amount. If at any time the
     aggregate outstanding amount of Revolving Loans plus the aggregate Letter
     of Credit Exposure 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
     plus the aggregate Letter of Credit Exposure to the amount of the Available
     Revolving Loan Commitment, and until such repayment is made, Lenders shall
     not be obligated to make Revolving 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)."

     (d) Subsection 1.8 of the Credit Agreement shall be amended and restated in
its entirety as follows:

     "1.8 Application of Repayments; Payment of Breakage Fees, Etc. All
     repayments made pursuant to Subsections 1.7(B), (C), (D), (E) and (F) shall
     be applied first, pro rata to Loans outstanding under the Term Loan A
     Facility, the Term Loan B Facility and, if and when applicable, the
     Incremental Term Loan Facility, subject to the succeeding paragraph of this
     Subsection 1.8; second, to Loans outstanding under the Revolving Loan
     Facility; third, to pay any outstanding Reimbursement Obligations; and
     fourth, to cash collateralize Letter of Credit Exposure pursuant to
     Subsection 1.16. All repayments made pursuant to Subsection 1.7(A) shall be
     applied first to Loans outstanding under the Revolving Loan Facility and
     then pro rata to Loans outstanding under the Term Loan A Facility, the Term
     Loan B Facility and, if and when applicable, the Incremental Term Loan
     Facility, subject to the succeeding paragraph of this Subsection 1.8. All
     repayments made pursuant to Subsections 1.6 and 1.7 shall first be applied
     to such of the applicable type of Loans as Borrower shall direct in writing
     and, in the absence of such direction, shall first be applied to the Base
     Rate Loan and then to such LIBOR Loans as Administrative Agent shall
     determine. All repayments and prepayments required or permitted hereunder
     shall be accompanied by payment of all applicable Breakage Fees and accrued
     interest on the amount repaid. All repayments and prepayments applied to


                                       3

<PAGE>

Second Agreement Regarding Amendments to Loan Documents/US Unwired

     Loans outstanding under the Term Loan A Facility, the Term Loan B Facility
     and, if and when applicable, the Incremental Term Loan Facility shall be
     applied to principal installments in the inverse order of maturity.

     Notwithstanding anything to the contrary in Subsection 1.7 or this
     Subsection 1.8, with respect to any repayment or prepayment described in
     Subsection 1.7 that is allocated to the Term Loan B Facility and, if and
     when applicable, the Incremental Term Loan Facility (the "Allocated Payment
     Amount"), at any time when the Term Loan A or Revolving Loans remain
     outstanding, Borrower will, in lieu of applying automatically such amount
     to the repayment or prepayment of the Term Loan B Facility and, if and when
     applicable, the Incremental Term Loan Facility, as provided in this
     Subsection 1.8, at least five Business Days prior to the date on which
     Borrower expects to make such repayment or prepayment, give Administrative
     Agent telephonic notice (promptly confirmed in writing) requesting that
     Administrative Agent prepare and provide each Lender with a Term Loan B
     Commitment and, if and when applicable, an Incremental Term Loan Commitment
     (each an "Electing Lender") a notice as described below (each a
     "Repayment/Prepayment Option Notice"). As promptly as practicable after
     receiving such notice from Borrower, Administrative Agent will send each
     Electing Lender a Repayment/Prepayment Notice which shall include an offer
     by Borrower to repay or prepay, as applicable, the portion of the Term Loan
     B Facility or, if and when applicable, the Incremental Term Loan Facility,
     as applicable, of such Electing Lender by an amount equal to such Electing
     Lender's Pro Rata Share of the Allocated Payment Amount on the date of the
     expected repayment or prepayment (each, a "Repayment/Prepayment Date").
     Each Electing Lender shall give notice to Administrative Agent prior to the
     Repayment/Prepayment Date if it elects to accept all or a portion of such
     repayment or prepayment, and each Electing Lender which has not notified
     Administrative Agent of whether it elects to accept such repayment or
     prepayment shall be deemed to have accepted such repayment or prepayment.
     On the Repayment/Prepayment Date, (i) Electing Lenders that have not
     expressly rejected their Repayment/Prepayment Option Notice shall be repaid
     or prepaid the amount indicated in such Repayment/Prepayment Notice and
     (ii) first, the Term Loan A Facility and, second, Revolving Loan Facility
     shall be repaid and the Revolving Commitment shall be reduced in the amount
     of the portion of Allocated Payment Amount expressly rejected by Electing
     Lenders."

     (e) Section 1 of the Credit Agreement is hereby amended to insert the
following as Subsection 1.16 of the Credit Agreement:

     "1.16 Letter of Credit.

          (A) Issuance. Subject to and upon the terms and conditions herein set
     forth, so long as no Default or Event of Default has occurred and is
     continuing, the Issuing Lender will, at any time and from time to time on
     and after June 6, 2002 and prior to the Revolving Facility Expiration Date,
     and upon request by the Borrower in accordance with the provisions of
     Subsection 1.16(B), issue for the account of the Borrower one or more
     irrevocable standby letters of credit denominated in dollars and in a form
     customarily used or otherwise approved by the Issuing Lender (together with
     all amendments, modifications and supplements thereto, substitutions
     therefor and renewals


                                       4

     and restatements thereof, collectively, the "Letters of Credit"). The
     Stated Amount of each Letter of Credit shall not be less than such amount
     as may be acceptable to the Issuing Lender. Letters of Credit may be issued
     for the purpose of providing credit enhancement in connection with trade
     payable transactions entered into by Borrower in the ordinary course of its
     business and as permitted herein. Notwithstanding the foregoing:

               (1) No Letter of Credit shall be issued the Stated Amount upon
          issuance of which (i) when added to the aggregate Letter of Credit
          Exposure of the Lenders at such time, would exceed $2,000,000 or (ii)
          when added to the sum of (A) the aggregate Letter of Credit Exposure
          of all Lenders at such time and (B) the aggregate principal amount of
          all Revolving Loans then outstanding, would exceed the Revolving Loan
          Commitment (as reduced from time to time) at such time;

               (2) No Letter of Credit shall be issued that by its terms expires
          more than one (1) year after its date of issuance; provided, however,
          that the Letters of Credit may, if requested by the Borrower, provide
          by its terms, and on terms acceptable to the Issuing Lender, for
          renewal for successive periods of one year or less (but not beyond the
          seventh day prior to the date set forth in clause (ii) of the
          definition of "Term Loan B Maturity Date,"), unless and until the
          Issuing Lender shall have delivered a notice of nonrenewal to the
          beneficiary of such Letter of Credit; and

               (3) The Issuing Lender shall be under no obligation to issue any
          Letter of Credit if, at the time of such proposed issuance, (i) any
          order, judgment or decree of any Governmental Authority or arbitrator
          shall purport by its terms to enjoin or restrain the Issuing Lender
          from issuing such Letter of Credit, or any Applicable Law applicable
          to the Issuing Lender or any request or directive (whether or not
          having the force of law) from any Governmental Authority with
          jurisdiction over the Issuing Lender shall prohibit, or request that
          the Issuing Lender refrain from, the issuance of letters of credit
          generally or such Letter of Credit in particular or shall impose upon
          the Issuing Lender with respect to such Letter of Credit any
          restriction or reserve or capital requirement (for which the Issuing
          Lender is not otherwise compensated) not in effect on the Second
          Closing Date, or any unreimbursed loss, cost or expense that was not
          applicable, in effect or known to the Issuing Lender as of the Second
          Closing Date and that the Issuing Lender in good faith deems material
          to it, or (ii) the Issuing Lender shall have actual knowledge, or
          shall have received notice from any Lender, prior to the issuance of
          such Letter of Credit that one or more of the conditions specified in
          Subsection 7.2 are not then satisfied (or have not been waived in
          writing as required herein) or that the issuance of such Letter of
          Credit would violate the provisions of Subsection 1.16(A)(l).

          (B) Notices. Whenever the Borrower desires the issuance of a Letter of
     Credit, the Borrower will give the Issuing Lender written notice with a
     copy to the Administrative Agent not later than 11:00 a.m. (Denver,
     Colorado time) three (3)


                                       5

Second Agreement Regarding Amendments to Loan Documents/US Unwired

     Business Days (or such shorter period as is acceptable to the Issuing
     Lender in any given case) prior to the requested date of issuance thereof.
     Each such notice (each being a "Letter of Credit Notice") shall be
     irrevocable, shall be given in the form of Exhibit B hereto and shall
     specify (i) the requested date of issuance, which shall be a Business Day,
     (ii) the requested Stated Amount and expiry date of the Letter of Credit,
     and (iii) the name and address of the requested beneficiary or
     beneficiaries of the Letter of Credit. The Borrower will also complete any
     other application procedures and documents required by the Issuing Lender
     in connection with the issuance of any Letter of Credit. Upon its issuance
     of any Letter of Credit, the Issuing Lender will promptly notify the
     Administrative Agent of such issuance, and the Administrative Agent will
     give prompt notice thereof to each Lender.

          (C) Participations. Immediately upon the issuance of any Letter of
     Credit, the Issuing Lender shall be deemed to have sold and transferred to
     each Lender, and each Lender shall be deemed irrevocably and
     unconditionally to have purchased and received from the Issuing Lender,
     without recourse or warranty, an undivided interest and participation,
     equal to such Lender's Pro Rata Share of the Revolving Loan Commitment, in
     such Letter of Credit, each drawing made thereunder and the obligations of
     the Borrower under this Agreement with respect thereto and any Collateral
     or other security therefor or guaranty pertaining thereto; provided,
     however, that the fee relating to Letters of Credit described in Subsection
     1.4(E)(2) shall be payable directly to the Issuing Lender as provided
     therein, and the other Lenders shall have no right to receive any portion
     thereof. Upon any change in the Revolving Loan Commitments of any of the
     Lenders pursuant to Subsection 8.1, with respect to all outstanding Letters
     of Credit and Reimbursement Obligations there shall be an automatic
     adjustment to the participations pursuant to this Subsection 1.16(C) to
     reflect the new Pro Rata Shares of the assigning Lender and the assignee.

          (D) Reimbursement. The Borrower hereby agrees to reimburse the Issuing
     Lender by making payment to the Administrative Agent, for the account of
     the Issuing Lender, in immediately available funds, for any payment made by
     the Issuing Lender under any Letter of Credit (each such amount so paid
     until reimbursed, together with interest thereon payable as provided
     hereinbelow, a "Reimbursement Obligation") immediately after, and in any
     event on the date of, such payment (provided that any such Reimbursement
     Obligation shall be deemed timely satisfied (but nevertheless subject to
     the payment of interest thereon as provided hereinbelow) if satisfied
     pursuant to a Borrowing of Revolving Loans made on the date of such
     payment), together with interest on the amount so paid by the Issuing
     Lender, to the extent not reimbursed prior to 11:00 a.m. (Denver, Colorado
     time) on the date of such payment or disbursement, (i) for the period from
     the date of the respective payment to the date of receipt by the Borrower
     from the Issuing Lender of notice of such payment, at the Base Rate plus
     the Base Rate Margin applicable to the Revolving Loan Facility as in effect
     from time to time during such period, and (ii) for the period from the date
     of receipt by the Borrower from the Issuing Lender of notice of such
     payment to the date the Reimbursement Obligation created thereby is
     satisfied, the Base Rate plus the Base Rate Margin applicable to the
     Revolving Loan Facility as in effect from time to time during such period
     plus, to the greatest extent permitted by applicable law, two percentage
     points (2.0%), such interest


                                       6

<PAGE>

Second Agreement Regarding Amendments to Loan Documents/US Unwired

     also to be payable on demand. The Issuing Lender will provide the
     Administrative Agent and the Borrower with prompt notice of any payment or
     disbursement made under any Letter of Credit, although the failure to give,
     or any delay in giving, any such notice shall not release, diminish or
     otherwise affect the Borrower' obligations under this Subsection 1.16(D) or
     any other provision of this Agreement. The Administrative Agent will
     promptly pay to the Issuing Lender any such amounts received by it under
     this Subsection 1.16(D).

          (E) Payment of Loans. In the event that the Issuing Lender makes any
     payment under any Letter of Credit and the Borrower shall not have timely
     satisfied in full its Reimbursement Obligation to the Issuing Lender
     pursuant to Subsection 1.16(D), and to the extent that any amounts then
     held in the Cash Collateral Account established pursuant to Subsection
     1.16(H) shall be insufficient to satisfy such Reimbursement Obligation in
     full, the Issuing Lender will promptly notify the Administrative Agent, and
     the Administrative Agent will promptly notify each Lender, of such failure.
     Notwithstanding that the Commitments may have expired or been terminated,
     if the Administrative Agent gives such notice prior to 11:00 a.m. (Denver,
     Colorado time) on any Business Day, each Lender will make available to the
     Administrative Agent, for the account of the Issuing Lender, its ratable
     share (equal to its Pro Rata Share of the Revolving Loan Commitment, or, if
     the Revolving Loan Commitment has expired or has been terminated, based
     upon the percentage of the aggregate Letter of Credit Exposure represented
     by such Lender's Letter of Credit Exposure) of the amount of such payment
     on such Business Day in immediately available funds. If the Administrative
     Agent gives such notice after 11:00 a.m. (Denver, Colorado time) on any
     Business Day, each such Lender shall make its ratable share of such amount
     available to the Administrative Agent on the next succeeding Business Day.
     If and to the extent any Lender shall not have so made its ratable share of
     the amount of such payment available to the Administrative Agent, such
     Lender agrees to pay to the Administrative Agent, for the account of the
     Issuing Lender, forthwith on demand such amount, together with interest
     thereon at the Federal Funds Rate for each day from such date until the
     date such amount is paid to the Administrative Agent. The failure of any
     Lender to make available to the Administrative Agent its ratable share of
     any payment under any Letter of Credit shall not relieve any other Lender
     of its obligation hereunder to make available to the Administrative Agent
     its ratable share of any payment under any Letter of Credit on the date
     required, as specified above, but no Lender shall be responsible for the
     failure of any other Lender to make available to the Administrative Agent
     such other Lender's ratable share of any such payment. Each such payment by
     a Lender under this Subsection 1.16(E) of its ratable share of an amount
     paid by the Issuing Lender shall constitute a Revolving Loan by such Lender
     (the Borrower being deemed to have given a timely Notice of Borrowing
     therefor) and shall be treated as such for all purposes of this Agreement;
     provided that for purposes of determining the aggregate Available Revolving
     Loan Commitment immediately prior to giving effect to the application of
     the proceeds of such Revolving Loans, the Reimbursement Obligation being
     satisfied thereby shall be deemed not to be outstanding at such time.

          (F) Payment to Lenders. Whenever the Issuing Lender receives a payment
     in respect of a Reimbursement Obligation as to which the Administrative
     Agent has


                                       7

<PAGE>

Second Agreement Regarding Amendments to Loan Documents/US Unwired

     received, for the account of the Issuing Lender, any payments from the
     Lenders pursuant to Subsection 1.16(E), the Issuing Lender will promptly
     pay to the Administrative Agent, and the Administrative Agent will promptly
     pay to each Lender that has paid its ratable share thereof, in immediately
     available funds, an amount equal to such Lender's ratable share (based on
     the proportionate amount funded by such Lender to the aggregate amount
     funded by all Lenders) of such Reimbursement Obligation.

          (G) Obligations Absolute. The Reimbursement Obligations of the
     Borrower, and the obligations of the Lenders under Subsection 1.16(E) to
     make payments to the Administrative Agent, for the account of the Issuing
     Lender, with respect to Letters of Credit, shall be irrevocable, shall
     remain in effect until the Issuing Lender shall have no further obligations
     to make any payments or disbursements under any circumstances with respect
     to any Letter of Credit, and, except to the extent resulting from any gross
     negligence or willful misconduct on the part of the Issuing Lender, shall
     be absolute and unconditional, shall not be subject to counterclaim, setoff
     or other defense or any other qualification or exception whatsoever and
     shall be made in accordance with the terms and conditions of this Agreement
     under all circumstances, including, without limitation, any of the
     following circumstances:

               (1) Any lack of validity or enforceability of this Agreement, any
          of the other Loan Documents or any documents or instruments relating
          to any Letter of Credit;

               (2) Any change in the time, manner or place of payment of, or in
          any other term of, all or any of the Obligations in respect of any
          Letter of Credit or any other amendment, modification or waiver of or
          any consent to departure from any Letter of Credit or any documents or
          instruments relating thereto, in each case whether or not the Borrower
          has notice or knowledge thereof;

               (3) The existence of any claim, setoff, defense or other right

               (5) Any defense based upon the failure of any drawing under a
          Letter of Credit to conform to the terms of the Letter of Credit
          (provided that any draft, certificate or other document presented
          pursuant to such Letter of Credit appears on its face to comply with
          the terms thereof), any nonapplication or misapplication by the
          beneficiary or any transferee of the proceeds of such drawing or any

     Any action taken or omitted to be taken by the Issuing Lender under or in
     connection with any Letter of Credit, if taken or omitted in the absence of
     gross negligence or willful misconduct, shall be binding upon the Borrower
     and each Lender and shall not create or result in any liability of the
     Issuing Lender to the Borrower or any Lender. It is expressly understood
     and agreed that, for purposes of determining whether a wrongful payment
     under a Letter of Credit resulted from the Issuing Lender's gross
     negligence or willful misconduct, (i) the Issuing Lender's acceptance of
     documents that appear on their face to comply with the terms of such Letter
     of Credit, without responsibility for further investigation, regardless of
     any notice or information to the contrary, (ii) the Issuing Lender's
     exclusive reliance on the documents presented to it under such Letter of
     Credit as to any and all matters set forth therein, including the amount of
     any draft presented under such Letter of Credit, whether or not the amount
     due to the beneficiary thereunder equals the amount of such draft and
     whether or not any document presented pursuant to such Letter of Credit
     proves to be insufficient in any respect (so long as such document appears
     on its face to comply with the terms of such Letter of Credit), and whether
     or not any other statement or any other document presented pursuant to such
     Letter of Credit proves to be forged or invalid or any statement therein
     proves to be inaccurate or untrue in any respect whatsoever, and (iii) any
     noncompliance in any immaterial respect of the documents presented under
     such Letter of Credit with the terms thereof shall, in each case, be deemed
     not to constitute gross negligence or willful misconduct of the Issuing
     Lender.

          (H) Cash Collateral Account At any time and from time to time (i)
     after the occurrence and during the continuance of an Event of Default, the
     Administrative Agent, at the direction or with the consent of the Requisite
     Lenders, may require the Borrower to deliver to the Administrative Agent
     such additional amount of cash as is equal to the aggregate Stated Amount
     of all Letters of Credit at any time outstanding (whether or not any
     beneficiary under any Letter of Credit shall have drawn or be entitled at
     such time to draw thereunder) and (ii) in the event of a prepayment under
     Subsection 1.6(D), or to the extent any amount of a required prepayment

     or (F) remains after prepayment of all outstanding Revolving Loans and
     Reimbursement Obligations and termination of the Revolving Loan Commitment
     as contemplated by Subsection 1.8, the Administrative Agent will retain
     such amount as may then be required to be retained, such amounts to be held
     by the Administrative Agent in a cash collateral account (the "Cash
     Collateral Account"). The Borrower hereby grants to the Administrative
     Agent, for the benefit of the Issuing Lender and the Lenders, a Lien upon
     and security interest in the Cash Collateral Account and all amounts held
     therein from time to time as security for Letter of Credit Exposure, and
     for application to the Borrower's Obligations as and when the same shall
     arise. The Administrative Agent shall have exclusive dominion and control,
     including the exclusive right of withdrawal, over such account. Other than
     any interest on the investment of such amounts in Cash Equivalents, which
     investments shall be made at the direction of the Borrower (unless a
     Default or Event of Default shall have occurred and be continuing, in which
     case the determination as to investments shall be made at the option and in
     the discretion of the Administrative Agent), amounts in the Cash Collateral
     Account shall not bear interest. interest and profits, if any, on such
     investments shall accumulate in such account. In the event of a drawing,
     and subsequent payment by the Issuing Lender, under any Letter of Credit at
     any time during which any amounts are held in the Cash Collateral Account,
     the Administrative Agent will deliver to the Issuing Lender an amount equal
     to the Reimbursement Obligation created as a result of such payment (or, if
     the amounts so held are less than such Reimbursement Obligation, all of
     such amounts) to reimburse the Issuing Lender therefor. Any amounts
     remaining in the Cash Collateral Account (including interest) after the
     expiration of all Letters of Credit and reimbursement in full of the
     Issuing Lender for all of its obligations thereunder shall be held by the
     Administrative Agent, for the benefit of the Borrower, to be applied
     against the Obligations in such order and manner as the Administrative
     Agent may direct. If the Borrower is required to provide cash collateral
     pursuant to Subsection 1.6(D), such amount (including, without limitation,
     interest), to the extent not applied as aforesaid, shall be returned to the
     Borrower on demand, provided that after giving effect to such return (i)
     the sum of (x) the aggregate principal amount of all Revolving Loans
     outstanding at such time and (y) the aggregate Letter of Credit Exposure of
     all Lenders at such time would not exceed the aggregate Revolving Loan
     Commitment (as reduced from time to time) at such time and (ii) no Default
     or Event of Default shall have occurred and be continuing at such time. If
     the Borrower is required to provide cash collateral as a result of an Event
     of Default, such amount (to the extent not applied as aforesaid) shall be
     returned to the Borrower within three (3) Business Days after all Events of
     Default have been cured or waived."

     (f) Subsection 6.2 of the Credit Agreement is hereby amended and restated
in its entirety as follows:

          "6.2 Suspension of Commitments. Upon the occurrence of any Default or
     Event of Default, the Issuing Lender may cease issuing Letters of Credit
     and the Administrative Agent and each Lender, without notice or demand, may
     immediately cease making additional Loans and cause its obligation to lend
     its Pro Rata Share of each Loan Commitment to be suspended; provided that,
     in the case of a Default, if the subject condition or event is waived,
     cured or removed by Requisite Lenders within any

     Commitments shall be reinstated."

     described in the foregoing Subsections 6.1(F) or 6.1(G), the unpaid
     principal amount of and accrued interest and fees on the Loans and all
     other Obligations shall automatically become immediately due and payable,
     without presentment, demand, protest, notice of intent to accelerate,
     notice of acceleration or other requirements of any kind, all of which are
     hereby expressly waived by Borrower, and the obligations of Administrative
     Agent and Lenders to make Loans or of Issuing Lender to issue Letters of
     Credit shall thereupon terminate. Upon the occurrence and during the
     continuance of any other Event of Default, Administrative Agent may, and
     upon written demand by Requisite Lenders shall, by written notice to
     Borrower (i) declare all or any portion of the Loans and all or some of the
     other Obligations to be, and the same shall forthwith become, immediately
     due and payable together with accrued interest thereon, and upon such
     acceleration the obligations of Administrative Agent and Lenders to make
     Loans and the obligations of the Issuing Lender to the issue Letters of
     Credit shall thereupon terminate and (ii) direct the Borrower to deposit
     (and the Borrower hereby agrees, forthwith upon receipt of notice of such
     direction from the Administrative Agent, to deposit) with the
     Administrative Agent from time to time such additional amount of cash as is
     equal to the aggregate Stated Amount of all Letters of Credit then
     outstanding (whether or not any beneficiary under any Letter of Credit
     shall have drawn or be entitled at such time to draw thereunder), such
     amount to be held by the Administrative Agent in the Cash Collateral
     Account as security for the Letter of Credit Exposure as described in

     Loans bears to the aggregate of all outstanding Revolving Loans at such

Second Agreement Regarding Amendments to Loan Documents/US Unwired

                STANDBY LETTER OF CREDIT REIMBURSEMENT AGREEMENT

To:   CoBank, ACB

In consideration of your issuing the Standby Letter of Credit (herein called the
"Credit") applied for by the application on the reverse side hereof, we hereby
agree as follows:

1. We will pay you on demand at such place and in such manner as you shall
direct, in United States currency and in immediately available funds, the amount
of each draft drawn or instrument paid under the Credit, as well as commission
and customary charges associated with the issuance of the Credit. If the Credit
is payable in a foreign currency, we will pay you on demand an amount in United
States currency equivalent to your actual cost of settling your obligation in
the foreign currency. We also authorize you to charge our accounts with you for
all moneys so paid or for which you become liable under the Credit. In addition
to commissions, fees, and amounts otherwise payable with respect to the issuance
of the Credit, we shall pay you on demand such amounts as you shall determine
are necessary to compensate you for any cost attributable to your issuing or
having outstanding such Credit resulting from the application of any law or
regulation concerning any reserve, assessment, capital adequacy or similar
requirements relating to letters of credit, or the reimbursement agreements with
respect thereto, or to similar liabilities or assets of banks, whether existing
at the time of the issuance of the Credit or adopted thereafter. Each payment
hereunder shall be made with interest from the date of payment by you to the
date of reimbursement by us at the rate announced by you from time to time
during that period as your National Variable Rate.

2. In furtherance and extension and not in limitation of the specific provisions
set forth above, we agree: (a) that you and your correspondents may receive and
accept or pay as complying with the terms of the Credit any drafts, documents,
or certificates, otherwise in order, signed by any person purporting to be an
administrator, executor, trustee in bankruptcy, debtor in possession, assignee
for the benefit of creditors, liquidator, receiver, or other legal
representative of the party authorized under the Credit to draw or issue such
instruments or other documents; (b) that any action taken or omitted by you or
by your correspondents under or in connection with the Credit, if taken or
omitted with honesty in fact, shall be binding on us and shall not put you or
your correspondents under any resulting liability to us; (c) that you shall not
be responsible for any act, error, neglect, default, omission, insolvency or
failure in business of any of your correspondents; and (d) that we will
indemnify you against and hold you harmless from all loss, damage, cost and
expense (including attorneys' fees and expenses) arising out of (i) your
issuance of, or any other action taken by you in connection with, the Credit,
other than loss or damage resulting from your gross negligence or willful
misconduct, and (ii) claims or legal proceedings incident to the collection of
amounts owed by us hereunder, or the enforcement of your rights or the rights of
others under the Credit, including, without limitation, legal proceedings
relating to any court order, injunction or other process or decree restraining
or seeking to restrain you from paying any amount under the Credit.

3. In the event (a) we fail to make any payment owing hereunder when the same
shall become due and payable; or (b) we make an assignment for the benefit of
creditors; or (c) we apply for, consent to, or acquiesce in the appointment of a
trustee, receiver, or other custodian for ourselves or any of our property; or
(d) we commence or have commenced against us any proceeding under any bankruptcy
reorganization, arrangement, readjustment of debt, dissolution, or liquidation
law or statue of any jurisdiction; or (e) we are in default to you under any
other agreement between us; or (f) any governmental regulatory authority takes
or institutes action which, in your opinion, will affect our ability to
reimburse you hereunder, then, in any such event, the amount of the Credit,
together with any amounts payable by us in connection therewith, shall, at your
option, become immediately due and payable. To the extent that any amount paid
by us pursuant to this Section 3 shall not then be due under the terms of the
Credit, such payment shall serve as security for our obligation to indemnify you
for any amounts subsequently disbursed by you pursuant to the Credit.
Furthermore, upon the institution of any legal proceeding as described in, or
similar to those described in, Section 2(d)(ii), hereof, or in the event a
deterioration in our financial condition causes you to feel insecure with regard
to our ability to reimburse you hereunder, we will, on demand, assign and
deliver to you, as security for our obligation to indemnify you, collateral of a
type and value satisfactory to you, or make such cash payment as you may
require.

4. This Agreement and your rights hereunder shall continue unimpaired, and we
shall be and remain obligated in accordance with the terms and provisions
hereof, notwithstanding any delay, extension of time, renewal, compromise or
other indulgence or modification granted or agreed to by you, with or without
notice to or approval by us, in respect of our indebtedness to you under this
Agreement.

5. You shall be fully protected in, and shall incur no liability to us for,
acting upon any oral, telephone, teleprocess or other instructions which you in
good faith believe to have been given by any authorized person, and in no event
shall you be liable for special, consequential or punitive damages. You may, at
your option, use any means of verifying any instructions received by you and may
also, at your option, refuse to act on any oral, telephone, teleprocess or other
instruction or any part thereof, without incurring any responsibility for any
loss, liability or expenses arising out of such refusal.

6. The Uniform Customs and Practice as most recently published by the
International Chamber of Commerce (hereafter called the "UCP") shall in all
respects be deemed a part hereof as fully as if incorporated herein, and shall
apply to the Credit. This agreement shall be governed by the laws of the State
of the United States of America in which the Credit is issued, except to the
extent that such laws are inconsistent with the UCP. We hereby irrevocably agree
to submit to the jurisdiction of the courts of that State and of any United
States District Court in that State for the resolution of any disputes
hereunder. In any such proceeding, service of process may be made upon us by
registered or certified mail addressed to us at the address set forth herein, or
at the last known address your records reflect for us.

7. If any provision or clause of the Agreement or the application thereof to any
person or circumstance is invalid, illegal, or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect other
provisions, clauses or applications of this Agreement which can be given effect,
and this Agreement shall be construed as if the invalid, illegal or
unenforceable provision, clause or application had never been contained herein.

8. This Agreement shall be binding upon our respective successors and permitted
assigns and shall inure to the benefit of and be enforceable by you, your
successors and assigns; provided, however, that without your consent we cannot
assign our rights or obligations hereunder. You may assign or transfer this
Agreement.

9. During the continuance of any default enumerated in Section 3 hereof, any
sums credited by or due from you to us may be set off, without prior notice,
against any liabilities, direct or indirect, absolute or contingent, due or to
become due, now existing or hereafter arising, that we may have to you.

We waive notice of your acceptance of this Agreement.
