                        CAMERON COMMUNICATIONS SERVICE AGREEMENT

This Agreement is made this day June 10, 1999, by and between CAMERON
COMMUNICATIONS CORPORATION, a Louisiana Corporation ("Supplier") and US UNWIRED
CORPORATION ("Customer"), a Louisiana Corporation.

                             1. SERVICE AND P.O.P.

(A) Supplier agrees to provide Customer with telecommunication termination
services and/or origination "800" Services (collectively the Service). Customer
shall be solely responsible for all capacity costs necessary to access the
service. The service shall be provided to the LATA's, at the rates and upon the
terms specified herein and on Schedule 1 which is attached hereto. Customer may
be required to pay a deposit prior to the initiation of service. Supplier
reserves the right to review customer's monthly bills and payment history on a
quarterly basis and if deemed necessary, may increase the deposit not to exceed
the amount of one (1) month's average bill.

(B) Requests for the service shall be documented by service interconnection
orders (SIO), signed by both parties, which shall specify the service
commencement date, all applicable rates and charges and any other terms and
conditions agreed to by the parties. To the extent that the terms and condition
of this Agreement and Schedule 1 conflict with the terms and conditions of any
SIO, the terms of the service agreement shall control.

(C) With Supplier's prior written approval customer may postpone a service
commencement date. No more than one (1) postponement shall be allowed for a
service commencement date and the cumulative length of all such postponements
shall not exceed fifteen (15) days. All additional costs and expenses incurred
by Supplier in connection with the postponement of a service commencement date
shall be charged to customer and shall be due and payable according to the terms
hereof.

(D) Supplier reserves the right to add or delete service offerings during the
term hereof and to increase it's rates upon not less than thirty (30) days
advance notice. In the event of a domestic price increase customer may terminate
this Agreement, without liability, by giving written notice at least ten (10)
days prior to the effective date of the price increase.

(E) Customer shall provide Supplier with regular forecasts regarding the number
of minutes expected to be terminated in various LATA's and/or Tandems, so as to
enable Supplier to arrange network configurations.

(F) Customer shall provide Supplier with a written certification (The
Certification) of the percentage of Interstate and Intrastate minutes of use
relevant to the minutes of traffic to be terminated in the state where each
Service Interconnection is made. The certification shall be provided by Customer
prior to the start of Service for each terminating traffic service
interconnection. Customer shall issue recertifications on no less than an annual
basis. In the event Customer fails to make such certifications, the relevant
minutes of use will be deemed to be subject to the Intrastate Rates set forth on
Schedule 1. Customer agrees to make its call detail records, billing system, and
other necessary information available to Supplier or it's designee for the
purpose of verifying Customer's Interstate/Intrastate minutes of traffic and to
indemnify and hold Supplier harmless from any liability Supplier incurs in the
event Customer's certification is inaccurate.

(G) All terminating fields will utilize FG-B or FG-D where available to produce
a toll-quality service (Bell Tech Ref. TR-NPL-000334). Other than for reasons of
cable cut or force majeure availability will meet P. 01 grade of service over
any 90 day period. Supplier will coordinate any system maintenance with Customer
if such maintenance is likely to produce a service interruption.

(H) Supplier shall designate the point of presence ("P.O.P.") for Customer to
access the service.

                                    2. TERM

Each DS-1 interconnection with Supplier shall be for a minimum term of one (1)
year from date of installation and shall thereafter continue on a month to month
term unless terminated by either party. Termination for each individual DS-1
interconnection shall be effective, at the end of the minimum term or during the
month to month continuation thereof, upon ninety (90) days advance written
notice.

                           3. SERVICE INTERCONNECTION

(A) There shall be a required minimum monthly usage (MMU) for each DS-1
interconnection of 100,000 minutes per monthly billing period. Customer shall
have sixty (60) days from date of initial service to reach it's MMU on the firs
DS-1 interconnection and sixty (60) days on each subsequent DS-1
interconnection. Customer's MMU requirement for each individual DS-1 shall be
met whenever the average monthly usage for all DS-1's equals or exceeds 100,000
minutes.

(B) If Customer fails to meet it's MMU requirement for any given billing period,
Customer shall pay an additional per minute charge of $0.01 on the difference
between MMU and actual monthly usage.

Example:      100,000     Is the Minimum Monthly Usage per DS-1
              -80,000     Is the Actual Monthly Usage
              -------
               10,000     Minutes @ $0.01=100.00 additional charge

(C) For each billing period, 80% of Customers total service minutes for
terminated calls shall be to tandems owned and operated by a Regional Bell
Operating Company with tariffed access charges (RBOC termination's). If Customer
fails to meet this RBOC termination requirement, Customer shall pay an
additional per minute charge of $0.02 on the number of minutes by which non-RBOC
termination's exceed 20% of the total monthly service minutes.

                             4. PAYMENT & BILLING

(A) Supplier will provide Customer with a monthly bill itemizing all: call
termination charges, monthly prepayment charges, port rentals, and other charges
owed by Customer to Supplier for the Services being billed. All domestic calls
will be billed in six (6) second increments rounded to the next highest one-
tenth minute thereafter. All international calls, with the exception of Mexico,
will be billed in six (6) second increments and subject to a thirty (30) second
minimum charge. Calls to Mexico will be billed in full one (1) minute
increments. International rates are subject to change

                    CAMERON COMMUNICATIONS SERVICE AGREEMENT

with a seven (7) day written notice from Supplier to Customer. All amounts due
Supplier are payable in full within twenty (20) days after receipt of invoice.
Delinquent amounts shall bear interest at the rate of 1.5% per month or the
highest lawful rate whichever is lower. It shall not be a defense to nonpayment
that all or a portion of the charges for the service were incurred by
unauthorized users.

(B) Written requests by Customer for billing adjustments together with all
supporting documentation must be received by Supplier within thirty (30) days
from date of invoice or the right to a billing adjustment shall be waived. In
the event of a billing dispute, Customer shall timely pay the undisputed amounts
and the parties shall promptly resolve the dispute by mutual agreement or by
arbitration as provided for herein.

(C) Excluding taxes on Supplier's income, all federal, state and local taxes
determined by Supplier to be due on services provided under this Agreement shall
be charged to Customer and be due and payable according to the terms hereof.

                                  5. DEFAULT

(A) When a party fails to timely pay any payment due hereunder or breaches any
of the other material terms hereof, or breaches any of the material terms of any
other written contract between the parties, such party shall be deemed in
default.

(B) Upon ten (10) days written following a default in payment, Supplier may
suspend service to Customer until all arrearages together with interest thereon
have been paid in full.

(C) Upon such a default in payment that is not cured within thirty (30) days
from date of suspension of service, Customer shall pay to Supplier as
liquidated damages an amount equal to it's most recent monthly bill or the
average of it's monthly bills for the period this Agreement was in effect, which
ever is greater, multiplied by the number of months remaining in the initial
term or if in a continuation thereof then by No. 3.

(D) Upon thirty (30) days notice following any other default the non-defaulting
party may terminate this Agreement upon the other party's failure to cure the
alleged default.

(E) Upon suspension or termination of this Agreement the non-defaulting party
may pursue all remedies available to it under the terms hereof and under any
applicable law.

                          6. LIMITATION OF LIABILITY

(A) Supplier shall not be liable for delays in installation, commencement or
restoration of the service; for any temporary or permanent cessation of service;
for errors, malfunctions, delays or defects in transmission of the service; for
loss or damage occasioned by acts of god, fire, elements, labor disputes,
shortages, utility curtailments, power failures, explosions, cable cut and other
catastrophes; for indirect, special, incidental, or consequential damages
including but not limited to lost profits or revenues; for punitive damages
arising from a breach of this Agreement, for injury to

or death of any person and for damage to or loss of any property arising out of
or attributable to it's operations and performance under this Agreement.

(B) Supplier makes no warranty, express, implied or statutory, as to the
description, quality, merchantability, completeness, or fitness for any purpose
of the service, local access or any other matter all of which warranties are
hereby excluded and disclaimed.

(C) Supplier shall not be required nor obligated to provide alternative routing
with respect to any transmission capacity provided pursuant to this Agreement.


                              7. INDEMNIFICATION

Each party shall indemnify, defend and hold harmless the other party, its
directors, officers, employees, and agents, successors, and assigns, from all
damages, costs, expenses and liabilities, including reasonable attorney's fees
and disbursements, sustained in any action commenced by any third party in
connection with the indemnifying party's performance of its obligations and
duties under this Agreement except for those damages, costs, expenses, and
liabilities arising from the gross negligence or willful misconduct of the other
party. The indemnified party shall promptly notify the other party of any such
suit or claim.

                       8. APPLICABLE LAW AND ARBITRATION

This Agreement shall be construed and interpreted in accordance with Louisiana
law. Any controversy or claim arising out of or related to this Agreement shall
be submitted by the parties to arbitration in accordance with the commercial
arbitration rules of the American Arbitration Association. Such arbitration
shall be conducted in the City and Parish of Lake Charles, Louisiana and both
parties expressly consent to jurisdiction over them of the Louisiana courts to
compel arbitration, to enter any appropriate order or judgment based upon an
arbitration award, or to enter any other award or judgment based upon or in
furtherance of the arbitration. Further, the prevailing party shall be entitled
to an award of reasonable attorney fees incurred in connection with the
arbitration award, the judgment based thereon and all subsequent collection
efforts. No arbitration action arising out of this Agreement shall be brought
by either party more than one (1) year after the cause of action has accrued.

                         9. CONFIDENTIALITY AGREEMENT

Supplier's business affairs and operations shall be deemed confidential.
Customer, it's officers, directors, partners, employees, affiliates, agents and

information to only those third parties as may be required to fulfill it's
obligations hereunder. Customer shall be fully liable for any breach of
confidentiality by itself, it's agents and representatives.
