                    COMPETITIVE ADVANCE AND
              REVOLVING CREDIT FACILITY AGREEMENT


         COMPETITIVE ADVANCE AND REVOLVING CREDIT FACILITY
AGREEMENT dated as of October 17, 1995, among CENTURY TELEPHONE
ENTERPRISES, INC., a Louisiana corporation (the "Borrower"), the banks listed on
the signature  pages hereof (the  "Banks"),  BANK ONE,  TEXAS,  N.A., a national
banking association, as agent for the Banks (in such capacity, the "Agent"), and
as auction administration agent (in such capacity,  the "Auction  Administration
Agent").

         The Borrower has  requested  the Banks to extend credit to the Borrower
in order to enable it to borrow  on a  revolving  credit  basis on and after the
date hereof and at any time and from time to time prior to the Termination  Date
(as herein defined) a principal  amount not in excess of $70,000,000 at any time
outstanding.  The Borrower has also  requested  the Banks to provide a procedure
pursuant to which the Borrower may designate that all of the Banks be invited to
bid on an uncommitted basis on borrowings by the Borrower scheduled to mature on
or prior to the Termination Date. The Banks are willing to extend such credit to
the  Borrower on the terms and  conditions  herein set forth.  Accordingly,  the
Borrower, the Agents, and the Banks agree as follows:


SECTION 1.                 DEFINITIONS.

     1.1 Certain Defined Terms. As used in this Agreement, the following terms
shall have the following meanings (such meanings to be equally applicable to
both the singular and plural forms of the terms defined):

          "Adjusted   Consolidated   Net  Worth"  means,   as  of  the  date  of
determination,  Consolidated  Net Worth  minus (i)  deferred  assets  other than
prepaid insurance,  prepaid taxes, prepaid interest,  extraordinary retirements,
and deferred  charges  where such deferred  charges are  considered by Tribunals
when  setting  rates,   (ii)  patents,   copyrights,   trademarks,   tradenames,
franchises, experimental expense, goodwill (other than goodwill arising from the
purchase  of capital  stock or assets of a Person  engaged in the  telephone  or
cellular mobile communications  business) and similar intangible or intellectual
property,  and (iii)  unamortized  debt  discount  and expense  (other than debt
discount and expense of the Companies located in jurisdictions  where such items
are considered by Tribunals when
setting rates).

         "Affiliate" means a Person that directly,  or indirectly through one or
more  intermediaries,  controls or is controlled  by or is under common  control
with another Person.

         "Agent" is defined in the introduction to this Agreement.

         "Agents" means the Agent and the Auction Administration Agent.



                                    -1-






         "Agreement"  means  this  Competitive   Advance  and  Revolving  Credit
Facility Agreement, as the same may be amended,  supplemented,  or modified from
time to time.

         "Applicable  Lending  Office"  means,  with respect to each Bank,  such
Bank's Domestic  Lending Office in the case of a Base Loan, or a Fixed Rate Loan
and such Bank's Eurodollar Lending Office in the case of a Eurodollar Loan.

          "Auction  Administration Agent" is defined in the introduction to this
Agreement.

         "Banks"  means  those  banks  signatory  hereto  and  other  banks  and
financial  institutions  which from time to time become party hereto pursuant to
the  provisions  of this  Agreement,  and,  except when used in  reference  to a
Committed Loan, a Committed  Borrowing,  a Committed Note, the Commitment of any
Bank or a related term, each Designated Lender.

         "Base Loan" means any Committed Loan with respect to which the Borrower
shall have selected an interest  rate based on the Base Rate in accordance  with
the provisions of Section 2.

         "Base Rate" means, for any date, a rate per annum (rounded upwards,  if
not already a whole multiple of 1/16 of 1%, to the next higher 1/16 of 1%) equal
to the  greatest  of (a) the Prime Rate in effect on such day or (b) the Federal
Funds Effective Rate in effect for such day plus 1/2 of 1%. For purposes hereof,
the term "Prime Rate" means that rate of interest  established from time to time
by the Agent as its  general  reference  rate of  interest,  after  taking  into
account such factors as the Agent may from time to time, in its sole discretion,
deem appropriate, it being understood,  however, that the Agent may from time to
time make  various  loans at rates of interest  having no  relationship  to such
general  reference rate of interest.  "Federal Funds Effective Rate" means,  for
any period, a fluctuating interest rate per annum equal for each day during such
period  to the  weighted  average  of  the  rates  on  overnight  federal  funds
transactions  with  members of the Federal  Reserve  System  arranged by federal
funds  brokers,  as  published  on the  succeeding  Business  Day by the Federal
Reserve Bank of New York, or, if such rate is not so published for any day which
is a  Business  Day,  the  average  of  the  quotations  for  the  day  of  such
transactions  received  by  the  Agent  from  three  federal  funds  brokers  of
recognized  standing selected by it. Any change in the Base Rate due to a change
in the Federal Funds  Effective Rate shall be effective on the effective date of
such change in the Federal  Funds  Effective  Rate.  If for any reason the Agent
shall have determined (which  determination  shall be conclusive absent manifest
error) that it is unable to ascertain the Federal Funds  Effective  Rate for any
reason, including,  without limitation, the inability or failure of the Agent to
obtain sufficient bids or publications in accordance with the terms hereof,  the
Base Rate shall be the Prime Rate until the  circumstances  giving  rise to such
inability no longer exist.

          "Board" means the Board of Governors of the Federal  Reserve System of
the United States.

         "Borrower" is defined in the introduction to this Agreement.

                  (c) The Auction Administration Agent shall promptly notify the
Borrower  by  telex  or  telecopier  of  all  the  Competitive  Bids  made,  the
Competitive  Bid Rate  and the  principal  amount  of each  Competitive  Loan in
respect of which a  Competitive  Bid was made and the  identity of the Bank that
made each bid on the date of delivery of  Competitive  Bids  pursuant to Section
2.2(b).  The Auction  Administration  Agent shall send a copy of all Competitive
Bids to the Borrower for its records as soon as practicable  after completion of
the bidding process set forth in this Section 2.2.

                  (d) The  Borrower  may in its  sole and  absolute  discretion,
subject only to provisions of this Section  2.2(d),  accept or reject any or all
of the Competitive Bids referred to in paragraph (c) above;  provided,  however,
that the aggregate amount of the Competitive




                                       -13-





Bids so  accepted by the  Borrower  may not exceed the  principal  amount of the
Competitive  Borrowing requested by the Borrower.  The Borrower shall notify the
Auction  Administration  Agent by telex or telecopier whether and to what extent
it has  decided  to  accept  or  reject  any or all of the bids  referred  to in
paragraph (c) above,  (i) in the case of Eurodollar  Loans, not later than 11:00
a.m., Dallas,  Texas time, two Business Days before the Borrowing Date specified
for a proposed  Competitive  Borrowing and (ii) in the case of Fixed Rate Loans,
not later than 11:00 a.m.,  Dallas,  Texas time, on the Borrowing Date specified
for a proposed Competitive Borrowing; provided, however, that (w) the failure by
the  Borrower to give such notice  shall be deemed to be a rejection  of all the
bids referred to in paragraph (c) above, (x) the Borrower shall not accept a bid
made at a particular  Competitive Bid Rate if the Borrower has decided to reject
a bid made at a lower  Competitive  Bid Rate,  (y) if the Borrower  shall accept
bids made at a particular  Competitive Bid Rate but shall be restricted by other
conditions  hereof from borrowing the principal  amount of Competitive  Loans in
respect of which  bids at such  Competitive  Bid Rate have been  made,  then the
Borrower  shall accept a pro rata  portion of each bid made at such  Competitive
Bid Rate based as nearly as  possible  on the  respective  principal  amounts of
Competitive  Loans  for  which  such  bids  were  made,  and (z) no bid shall be
accepted for a  Competitive  Loan unless such  Competitive  Loan is in a minimum
principal  amount  of  $3,000,000  and  an  integral   multiple  of  $1,000,000.
Notwithstanding  the foregoing,  if it is necessary for the Borrower to accept a
pro rata  allocation of the bids made in response to a  Competitive  Bid Request
(whether  pursuant to the events specified in clause (y) above or otherwise) and
the available  principal  amount of Competitive  Loans to be allocated among the
Banks is not sufficient to enable Competitive Loans to be allocated to each Bank
in a minimum  principal  amount  of  $3,000,000  and in  integral  multiples  of
$1,000,000,  then the  Borrower  shall  select  the Banks to be  allocated  such
Competitive  Loans and shall round  allocations up or down to the next higher or
lower multiple of $1,000,000 as it shall deem appropriate. A notice given by the
Borrower pursuant to this paragraph (d) shall be irrevocable.

                  (e) The Auction  Administration  Agent shall  promptly  notify
each bidding Bank whether or not its  Competitive  Bid has been accepted (and if
so, in what amount and at what Competitive Bid Rate) by telex or telecopier, and
each  successful  bidder  will  thereupon  become  bound,  subject  to the other
applicable  conditions  hereof, to make the Competitive Loan in respect of which
its bid has been accepted. After completing the notifications referred to in the
immediately  preceding  sentence,  the  Auction  Administration  Agent shall (i)
notify  the Agent of each  Competitive  Bid that has been  accepted,  the amount
thereof,  and the Competitive Bid Rate therefor and (ii) notify each Bank of the
aggregate principal amount of all Competitive Bids accepted.

                  (f) Upon receipt from the Agent of the LIBO Rate applicable to
any  Eurodollar  Loan to be made by any Bank pursuant to a Competitive  Bid that
has been  accepted  by the  Borrower  pursuant  to Section  2.2(d),  the Auction
Administration  Agent shall notify such Bank of (i) the applicable LIBO Rate and
(ii) the sum of the applicable LIBO Rate plus the Margin bid by such Bank.





                                -14-





                  (g) No  Competitive  Borrowing  shall  be  made  within  three
Business  Days of the  date  of any  other  Competitive  Borrowing,  unless  the
Borrower and the Auction Administration Agent shall mutually agree otherwise.

                  (h) If the Auction Administration Agent shall at any time have
a  Commitment  hereunder  and  shall  elect to submit a  Competitive  Bid in its
capacity as a Bank,  it shall  submit  such bid  directly  to the  Borrower  one
quarter of an hour  earlier  than the latest  time at which the other  Banks are
required to submit their bids to the Auction  Administration  Agent  pursuant to
paragraph (b) above.

     (i) All notices required by this Section 2.2 shall be made in accordance
with Section 9.6.

         2.3  Committed  Borrowing  Procedure.  In order to  effect a  Committed
Borrowing,  the Borrower shall hand deliver,  telex,  or telecopy to the Agent a
duly completed  request for Committed  Borrowing,  substantially  in the form of
Exhibit  A-2  hereto (a  "Notice of  Committed  Borrowing"),  (i) in the case of
Eurodollar  Loans, not later than 11:00 a.m.,  Dallas,  Texas time, two Business
Days before the Borrowing Date specified for a proposed Committed Borrowing, and
(ii) in the case of Base Loans, not later than 11:00 a.m.,  Dallas,  Texas time,
on the  Business  Day  which is the  Borrowing  Date  specified  for a  proposed
Committed Borrowing. No Fixed Rate Loan shall be requested or made pursuant to a
Notice of Committed  Borrowing.  Such notice shall be  irrevocable  and shall in
each case refer to this  Agreement  and specify (x) whether the Loans then being
requested are to be Eurodollar  Loans or Base Loans,  (y) the Borrowing  Date of
such Loans  (which shall be a Business  Day) and the  aggregate  amount  thereof
(which  shall not be less than  $500,000  and shall be an  integral  multiple of
$100,000), and (z) the Interest Period with respect thereto (which shall not end
later than the  Termination  Date).  If no Interest  Period with  respect to any
Eurodollar Loan is specified in any such Notice of Committed Borrowing, then the
Borrower  shall be deemed to have  selected  an  Interest  Period of one month's
duration. Promptly, and in any event on the same day the Agent receives a Notice
of Committed  Borrowing pursuant to this Section 2.3, the Agent shall advise the
other Banks of such Notice of Committed  Borrowing and of each Bank's portion of
the  requested  Committed  Borrowing  by telex  or  telecopier.  Each  Committed
Borrowing  shall  consist  of Loans of the same type made as of the same day and
having the same Interest Period.

         2.4  Refinancings.  The Borrower may  refinance  all or any part of any
Loan with a Loan of the same or a different type made pursuant to Section 2.2 or
Section 2.3,  subject to the  conditions  and  limitations  set forth herein and
elsewhere in this  Agreement,  including,  without  limitation,  refinancings of
Competitive  Loans with  Committed  Loans and Committed  Loans with  Competitive
Loans.  Any Loan or part thereof so  refinanced  shall be deemed to be repaid in
accordance  with Section 2.8 with the proceeds of a new Borrowing  hereunder and
the  proceeds of the new Loan,  to the extent  they do not exceed the  principal
amount of the Loan being refinanced, shall not be paid by the Banks to the Agent
or by the Agent to the Borrower pursuant to Section 2.7(c);  provided,  however,
that (i) if the principal  amount extended by a Bank in a refinancing is greater
than the principal amount extended by such




                                   -15-





Bank in the Borrowing being refinanced, then such Bank shall pay such difference
to the Agent for distribution to the Banks described in (ii) below,  (ii) if the
principal amount extended by a Bank in the Borrowing being refinanced is greater
than the principal  amount being extended by such Bank in the  refinancing,  the
Agent shall return the difference to such Bank out of amounts received  pursuant
to (i) above,  (iii) to the extent any Bank fails to pay the Agent  amounts  due
from it  pursuant to (i) above,  any Loan or portion  thereof  being  refinanced
shall not be deemed repaid in accordance  with Section 2.8 to the extent of such
failure and the Borrower  shall pay such amount to the Agent pursuant to Section
2.8, and (iv) to the extent the  Borrower  fails to pay to the Agent any amounts
due in  accordance  with Section 2.8 as a result of the failure of a Bank to pay
the Agent any  amounts  due as  described  in (iii)  above,  the  portion of any
refinanced  Loan deemed not repaid shall be deemed to be  outstanding  solely to
the Bank which has failed to pay the Agent  amounts  due from it pursuant to (i)
above to the full extent of such Bank's portion of such refinanced Loan.

         2.5 Fees. The Borrower  agrees to pay to each Bank,  through the Agent,
on each March 31, June 30,  September 30, and December 31 and on the Termination
Date,  in  immediately  available  funds,  a  facility  fee (a  "Facility  Fee")
calculated by multiplying  the  percentages  set forth below in the contexts set
forth below by the  Commitment of such Bank,  during the  preceding  quarter (or
shorter  period   commencing  with  the  date  hereof  and/or  ending  with  the
Termination Date):

==========================================================================

All  Facility  Fees  shall be  computed  by the Agent on the basis of the actual
number of days  elapsed  in a year of 365  days,  and  shall be  conclusive  and
binding for all purposes,  absent manifest  error.  The Facility Fee due to each
Bank shall  commence  to accrue on the date  hereof and shall cease to accrue on
the earlier of the  Termination  Date and the  termination  of the Commitment of
such Bank as provided herein.  Notwithstanding the foregoing,  in no event shall
any  Bank be  permitted  to  receive  any  compensation  hereunder  constituting
interest in excess of the Highest Lawful Rate.

         2.6 Termination  and Reduction of  Commitments.  (a) Subject to Section
2.12(b),  the Borrower may permanently  terminate,  or from time to time in part
permanently  reduce,  the  Total  Commitment,  in each  case  upon at least  ten
Business Days' prior written or telex




                                  -16-





notice to the Agent (who shall promptly  forward a copy thereof to each Bank and
the Auction  Administration  Agent).  Such notice shall specify the date and the
amount  of the  termination  or  reduction  of the Total  Commitment.  Each such
partial  reduction  of the  Total  Commitment  shall be in a  minimum  aggregate
principal amount of $5,000,000 and in an integral multiple of $1,000,000.

                  (b) On the Termination Date the Total Commitment shall be
zero.

                  (c) Each  reduction in the Total  Commitment  pursuant to this
paragraph  shall be made  ratably  among  the  Banks in  accordance  with  their
respective  Commitments.  Simultaneously  with any  termination  or reduction of
commitments pursuant to this paragraph,  the Borrower shall pay to the Agent for
the  accounts  of the  Banks  the  Facility  Fees  on the  amount  of the  Total
Commitment  so  terminated  or  reduced,   accrued  through  the  date  of  such
termination or reduction.

         2.7 Loans. (a) Each Borrowing made by the Borrower on any date shall be
(i) in the case of Competitive  Loans, in an integral multiple of $1,000,000 and
in a minimum  aggregate  principal  amount of $3,000,000 and (ii) in the case of
Committed Loans, in an integral  multiple of $100,000 and in a minimum aggregate
principal  amount of $500,000.  Competitive  Loans shall be made by the Banks in
accordance with Section  2.2(d),  and Committed Loans shall be made by the Banks
ratably in accordance with their respective Commitments on the Borrowing Date of
the Committed Borrowing; provided, however, that the failure of any Bank to make
any Loan shall not in itself  relieve any other Bank of its  obligation  to lend
hereunder. The initial Competitive Loan and Committed Loan by each Bank shall be
made  against  delivery  to such  Bank of an  appropriate  Competitive  Note and
Committed Note, respectively,  payable to the order of such Bank, as referred to
in Section 2.8.

                  (b) Each  Competitive  Loan  shall be a  Eurodollar  Loan or a
Fixed Rate Loan, and each  Committed  Loan shall be a Eurodollar  Loan or a Base
Loan, as the Borrower may request  subject to and in accordance with Section 2.2
or Section 2.3, as  applicable.  Each Bank may at its option make any Eurodollar
Loan by  causing a foreign  branch  of such  Bank to make such  Loan;  provided,
however, that any exercise of such option shall not affect the obligation of the
Borrower to repay such Loan in accordance  with the terms of the applicable Note
and  this  Agreement.  Loans  of more  than  one  interest  rate  option  may be
outstanding at the same time; provided,  however, that the Borrower shall not be
entitled to request any Loan which,  if made,  would  result in an  aggregate of
more than 10 separate  Borrowings being  outstanding  hereunder at any one time.
For  purposes  of  the  foregoing,  Loans  having  different  interest  Periods,
regardless  of  whether  they  commence  on the same date,  shall be  considered
separate Loans.

                  (c) Subject to Section  2.4,  each Bank shall make its portion
of each  Competitive  Borrowing  and each  Committed  Borrowing  on the proposed
Borrowing Date thereof by paying the amount required to the Agent in Dallas,  in
immediately  available funds not later than 12:00 noon, Dallas,  Texas time, and
the Agent shall by 2:00 p.m., Dallas,




                                      -17-





Texas time, credit the amounts so received to the general deposit account of the
Borrower  with the Agent or,  if Loans  are not made on such  date  because  any
condition  precedent to a Borrowing  herein  specified  shall not have been met,
return the amounts so received to the respective  Banks as soon as  practicable;
provided,  however,  if and to the  extent  the Agent  fails to return  any such
amounts to a Bank on the Borrowing Date for such Borrowing,  the Agent shall pay
interest on such  unreturned  amounts,  for each day from such Borrowing Date to
the date such amounts are returned to such Bank, at the Federal Funds  Effective
Rate.

         2.8 Notes.  The Competitive  Loans made by each Bank shall be evidenced
by a single  Competitive Note,  payable to the order of such Bank in a principal
amount  equal to the Total  Commitment.  The  Committed  Loans made by each Bank
shall be evidenced by a single  Committed Note payable to the order of such Bank
in a principal  amount equal to the  Commitment  of such Bank.  The  outstanding
principal  balance of each  Competitive Loan and Committed Loan, as evidenced by
the  relevant  Note,  shall be  payable on the last day of the  Interest  Period
applicable to such Loan.  Each Note shall bear interest from the date thereof on
the  outstanding  principal  balance  thereof  as set forth in  Section  2.9 and
Section  2.10.  Each Bank shall,  and is hereby  authorized  by the Borrower to,
endorse on the schedule attached to the relevant Note held by such Bank (or on a
continuation  of such  schedule  attached  to each  such  Note  and  made a part
thereof) or in its records relating such Note an appropriate notation evidencing
the date and amount of each  Competitive  Loan or Committed Loan, as applicable,
of such Bank, each payment or prepayment of principal of any Competitive Loan or
Committed Loan, as applicable,  and the other  information  provided for on such
schedule. The aggregate unpaid principal amount so recorded shall be presumptive
evidence  of the  principal  amount  owing by the  Borrower to a Bank and unpaid
under the Note of such Bank.  The failure of any Bank to make such a notation or
any error therein shall not in any manner affect the  obligation of the Borrower
to repay the Competitive  Loans or Committed Loans, as applicable,  made by such
Bank in accordance with the terms of the relevant Note.

         2.9 Interest on Loans.  (a) Subject to the  provisions of Section 2.10,
each  Eurodollar  Loan shall bear interest at a rate per annum  (computed on the
basis of the actual number of days elapsed over a year of 360 days) equal to the
lesser of (i) the Highest  Lawful  Rate and (ii) the LIBO Rate for the  Interest
Period  in effect  for such  Loan (A) plus or minus,  as the case may be, in the
case of each  Competitive  Loan, the Margin  specified by a Bank with respect to
such Loan in its  Competitive  Bid submitted  pursuant to Section 2.2(b) and (B)
plus,  in the  case  of  each  Committed  Loan,  the  Margin.  Interest  on each
Eurodollar  Loan shall be  payable  on each  Interest  Payment  Date  applicable
thereto.  The applicable  LIBO Rate for each Interest Period shall be determined
by the Agent, and such determination shall be conclusive absent manifest error.

                  (b) Subject to the provisions of Section 2.10,  each Base Loan
shall bear  interest at the rate per annum  (computed on the basis of the actual
number of days elapsed over a year of (x) 365 or 366 days, as the case may be if
the Base  Rate is based on the  Prime  Rate or (y) 360 days if the Base  Rate is
based on the Federal Funds Effective Rate)




                                    -18-





equal to the  lesser  of (i) the  Highest  Lawful  Rate and (ii) the Base  Rate.
Interest  on each Base Loan  shall be  payable  on each  Interest  Payment  Date
applicable  thereto.  The applicable Base Rate during each Interest Period shall
be determined by the Agent, and such  determination  shall be conclusive  absent
manifest error.

                  (c) Subject to the provisions of Section 2.10, each Fixed Rate
Loan  shall  bear  interest  at a rate per annum  (computed  on the basis of the
actual  number of days  elapsed over a year of 360 days) equal to the fixed rate
of interest  offered by the Bank making such Loan and  accepted by the  Borrower
pursuant  to Section  2.2.  Interest on each Fixed Rate Loan shall be payable on
each Interest Payment Date applicable thereto.

         2.10 Interest on Overdue Amounts.  If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder,  the Borrower shall on demand from time to time pay interest,  to
the extent  permitted by Law, on such defaulted amount up to (but not including)
the date of actual  payment  (after as well as  before  judgment)  at a rate per
annum  equal to the lesser of (i) the  Highest  Lawful Rate and (ii) the Default
Rate.

         2.11  Alternate Rate of Interest.  In the event,  and on each occasion,
that on the day two  Business  Days prior to the  commencement  of any  Interest
Period for a  Eurodollar  Loan,  the Agent  shall have  determined  that  dollar
deposits in the amount of the requested principal amount of such Eurodollar Loan
are not generally  available in the Eurodollar  Interbank Market, or that dollar
deposits of such Eurodollar  Loan are not generally  available in the Eurodollar
Interbank Market for the requested  Interest  Period,  or that the rate at which
such dollar  deposits are being offered will not  adequately  and fairly reflect
the cost to any Bank of making or maintaining  such  Eurodollar Loan during such
Interest Period, or that reasonable means do not exist for ascertaining the LIBO
Rate, the Agent shall, as soon as practicable thereafter,  give written or telex
notice of such  determination,  stating the specific  reasons  therefor,  to the
Borrower,  the Auction  Administration Agent, and the Banks. In the event of any
such  determination,  any request by the Borrower  for a Eurodollar  Loan shall,
until the circumstances giving rise to such notice no longer exist, be deemed to
be a request for a Base Loan. Each determination by the Agent hereunder shall be
conclusive absent manifest error.

         2.12  Prepayment  of Loans.  (a)  Prior to the  Termination  Date,  the
Borrower shall have the right at any time to prepay any Committed Borrowing,  in
whole or in part,  subject to the  requirements  of Section  2.15 but  otherwise
without premium or penalty,  but prepayment of Eurodollar Loans shall require at
least five Business  Days prior written or telex notice to the Agent;  provided,
however,  that each such partial  prepayment shall be in an integral multiple of
$100,000 and in a minimum aggregate principal amount of $100,000. Each notice of
prepayment shall specify the prepayment date and the aggregate  principal amount
of each  Borrowing  to be prepaid,  shall be  irrevocable  and shall  commit the
Borrower to prepay such  Borrowing by the amount  stated  therein.  The Borrower
shall not have the right to prepay any Competitive Borrowing.



                                    -19-





                  (b) On the date of any  termination  or reduction of the Total
Commitment  pursuant to Section 2.6(a), the Borrower shall pay or prepay so much
of the Loans as shall be necessary in order that the aggregate  principal amount
of the Loans  outstanding  will not exceed the Total  Commitment  following such
termination  or  reduction.  Subject  to the  foregoing,  any  such  payment  or
prepayment  shall be applied to such  Borrowing  or  Borrowings  as the Borrower
shall select.  All prepayments  under this paragraph shall be subject to Section
2.15 and Section 2.16.

                  (c)  All   prepayments   under  this  Section  2.12  shall  be
accompanied  by accrued  interest on the  principal  amount being prepaid to the
date of prepayment.

         2.13 Reserve Requirements; Change in Circumstances. (a) Notwithstanding
any other  provision  herein,  if after the date of this Agreement any change in
applicable Law or regulation or in the interpretation or administration  thereof
by any  Tribunal  charged  with the  interpretation  or  administration  thereof
(whether or not having the force of Law) (i) shall  change the basis of taxation
of payments to any Bank of the principal of or interest on any  Eurodollar  Loan
or Fixed  Rate  Loan  made by such Bank or any  other  fees or  amounts  payable
hereunder  (other than (x) Taxes  imposed on the overall net income of such Bank
by the  jurisdiction  in which  such  Bank has its  principal  office  or by any
political  subdivision or taxing authority  therein (or any Tax which is enacted
or adopted by such jurisdiction, political subdivision, or taxing authority as a
direct  substitute  for any such  Taxes)  or (y) any Tax,  assessment,  or other
governmental  charge that would not have been imposed but for the failure of any
Bank to comply  with any  certification,  information,  documentation,  or other
reporting  requirement),  (ii) shall  impose,  modify,  or deem  applicable  any
reserve,  special deposit,  or similar  requirement  against assets of, deposits
with or for the account  of, or credit  extended  by, such Bank,  or (iii) shall
impose on such  Bank or the  Eurodollar  Interbank  Market  any other  condition
affecting this Agreement or any Eurodollar  Loan or Fixed Rate Loan made by such
Bank,  and the result of any of the  foregoing  shall be to increase the cost to
such  Bank of  maintaining  its  Commitment  or of  making  or  maintaining  any
Eurodollar  Loan or Fixed Rate Loan or to reduce the amount of any sum  received
or  receivable  by such Bank  hereunder  (whether  of  principal,  interest,  or
otherwise) in respect  thereof by an amount deemed in good faith by such Bank to
be material,  then the  Borrower  shall pay to the Agent for the account of such
Bank such  additional  amount or amounts as will  compensate  such Bank for such
increase or reduction to such Bank upon demand by such Bank (through the Agent).
Notwithstanding  the  foregoing,  in no event  shall  any Bank be  permitted  to
receive  any  compensation  hereunder  constituting  interest  in  excess of the
Highest Lawful Rate.

                  (b) If any Bank shall have  determined  in good faith that the
adoption of any applicable law, rule, regulation, or guideline regarding capital
adequacy,  or any  change  therein,  or any  change  in  the  interpretation  or
administration  thereof by any Tribunal,  central  bank,  or  comparable  agency
charged with the interpretation or administration  thereof, or compliance by any
Bank (or any  lending  office  of such  Bank)  with  any  request  or  directive
regarding  capital adequacy (whether or not having the force of Law) of any such
authority,  central bank, or comparable  agency, has or would have the effect of
reducing  the rate of return on such  Bank's  capital  as a  consequence  of its
obligations  hereunder to a level below that which such Bank could have achieved
but for such adoption, change, or compliance




                                 -20-





(taking  into  consideration  such  Bank's  policies  with  respect  to  capital
adequacy)  by an amount  deemed by such Bank to be  material,  then from time to
time,  the  Borrower  shall pay to the Agent for the  account  of such Bank such
additional  amount or amounts as will  compensate  such Bank for such  reduction
upon demand by such Bank (through the Agent).  Notwithstanding the foregoing, in
no event  shall any Bank be  permitted  to receive  any  compensation  hereunder
constituting interest in excess of the Highest Lawful Rate.

                  (c) A certificate of a Bank setting forth in reasonable detail
(i) such  amount or amounts as shall be  necessary  to  compensate  such Bank as
specified  in  paragraph  (a) or (b)  above,  as the case  may be,  and (ii) the
calculation of such amount or amounts under clause (a)(i), shall be delivered to
the Borrower (with a copy to the Agent)  promptly after such Bank  determines it
is entitled to compensation under this Section 2.13, and shall be conclusive and
binding  absent  manifest  error.  The  Borrower  shall pay to the Agent for the
account of such Bank the amount shown as due on any such  certificate  within 15
days after its receipt of the same. In preparing such certificate, such Bank may
employ such  assumptions  and  allocations  of costs and expenses as it shall in
good faith deem reasonable and may use any reasonable  averaging and attribution
method.

                  (d) Failure on the part of any Bank to demand compensation for
any increased costs or reduction in amounts  received or receivable or reduction
in return on capital with respect to any Interest  Period shall not constitute a
waiver of such Bank's rights to demand  compensation  for any increased costs or
reduction in amounts  received or  receivable  or reduction in return on capital
with  respect  to  such  Interest  Period  or any  other  Interest  Period.  The
protection  of this Section 2.13 shall be available to each Bank  regardless  of
any possible contention of invalidity or inapplicability of the law, regulation,
or condition which shall have been imposed.

                  (e) In the event any Bank shall seek compensation  pursuant to
this Section 2.13, the Borrower may give notice to such Bank (with copies to the
Agents) that it wishes to seek one or more Eligible  Assignees (which may be one
or more of the Banks) to assume the  Commitment of such Bank and to purchase its
outstanding Loans and Notes. Each Bank requesting  compensation pursuant to this
Section 2.13 agrees to sell its Commitment,  Loans,  Notes, and interest in this
Agreement and the other Loan Papers to any such Eligible  Assignee for an amount
equal to the sum of the outstanding  unpaid principal of and accrued interest on
such  Loans  and Notes  plus all  other  fees and  amounts  (including,  without
limitation, any compensation claimed by such Bank under this Section 2.13 and as
to which such Bank has delivered the certificate  required by Section 2.13(c) on
or before the date such  Commitment,  Loans,  and Notes are  purchased) due such
Bank hereunder  calculated,  in each case, to the date such  Commitment,  Loans,
Notes, and interest are purchased. Following any such sale, such Bank shall have
no further Commitment or other obligation to the Borrower hereunder or under any
other Loan Paper.

                  (f) Notwithstanding  anything herein to the contrary,  no Bank
shall be entitled to any  compensation  under this  Section 2.13 with respect to
any Competitive Loan.




                                   -21-





                  (g) Without prejudice to the survival of any other obligations
of the Borrower  hereunder,  the  obligations of the Borrower under this Section
2.13 shall survive for one year after the  termination of this Agreement  and/or
the payment or assignment of any of the Notes.

         2.14 Change in Legality.  (a) Notwithstanding  anything to the contrary
herein  contained,  if any change in any or regulation or in the  interpretation
thereof  by any  Tribunal  charged  with the  administration  or  interpretation
thereof  shall make it unlawful for any Bank to make or maintain any  Eurodollar
Loan or to give effect to its  obligations  as  contemplated  hereby,  then,  by
written notice to the Borrower and to the Agents, such Bank may:

                  (i) declare that Eurodollar  Loans will not thereafter be made
         by such Bank hereunder, whereupon the Borrower shall be prohibited from
         requesting  Eurodollar  Loans  from such  Bank  hereunder  unless  such
         declaration is subsequently withdrawn; and

                  (ii) require that all outstanding  Eurodollar Loans made by it
         be  converted  to Base Loans,  in which  event (A) all such  Eurodollar
         Loans  shall  be  automatically  converted  to  Base  Loans  as of  the
         effective  date of such notice as provided in  paragraph  (b) below and
         (B) all payments and  prepayments  of principal  which would  otherwise
         have been applied to repay the converted Eurodollar Loans shall instead
         be applied to repay the Base Loans  resulting  from the  conversion  of
         such Eurodollar Loans.

                  (b) For  purposes  of  this  Section  2.14,  a  notice  to the
Borrower  (with a copy to the Agent) by any Bank pursuant to paragraph (a) above
shall be effective on the date of receipt thereof by the Borrower.

         2.15 Indemnity. The Borrower shall indemnify each Bank against any loss
or reasonable  expense which such Bank may sustain or incur as a consequence  of
(a) any failure by the Borrower to borrow  hereunder after a Notice of Committed
Borrowing  pursuant to Section 2 has been given or after  Competitive  Bids have
been  accepted,  (b)  any  payment,   prepayment,  or  conversion,   other  than
conversions under Section  2.14(a)(ii),  of a Eurodollar Loan or Fixed Rate Loan
required by any other  provision of this  Agreement or otherwise  made on a date
other than the last day of the applicable  Interest  Period,  (c) any default in
the  payment  or  prepayment  of the  principal  amount  of any Loan or any part
thereof or  interest  accrued  thereon,  as and when due and payable (at the due
date thereof, by notice of prepayment,  or otherwise),  or (d) the occurrence of
any Event of Default.  The indemnity of the Borrower pursuant to the immediately
preceding sentence shall include,  but not be limited to, any loss or reasonable
expense  sustained or incurred or to be sustained or incurred in  liquidating or
employing  deposits from third parties  acquired to effect or maintain such Loan
or any part  thereof  as a  Eurodollar  Loan or Fixed  Rate  Loan.  Such loss or
reasonable  expense shall include,  without  limitation,  an amount equal to the
excess,  if  any,  as  reasonably  determined  by each  Bank of (i) its  cost of
obtaining  the funds for the Loan  being  paid,  prepaid,  or  converted  or not
borrowed (based on the LIBO Rate or, in the case of a Fixed Rate Loan, the fixed
rate of interest applicable thereto) for the period from the date of



                                   -22-





such payment,  prepayment, or conversion or failure to borrow to the last day of
the Interest  Period for such Loan (or, in the case of a failure to borrow,  the
Interest  Period for the Loan which  would  have  commenced  on the date of such
failure to borrow) over (ii) the amount of interest (as reasonably determined by
such Bank) that would be realized by such Bank in reemploying the funds so paid,
prepaid, or converted or not borrowed for such period or Interest Period, as the
case may be. A  certificate  of each Bank  setting  forth any  amount or amounts
which such Bank is entitled to receive  pursuant to this  Section  2.15 shall be
delivered to the Borrower (with a copy to the Agent) and shall be conclusive, if
made in good faith,  absent manifest error.  The Borrower shall pay to the Agent
for the account of each Bank the amount shown as due on any  certificate  within
30 days after its  receipt of the same.  Notwithstanding  the  foregoing,  in no
event  shall  any  Bank be  permitted  to  receive  any  compensation  hereunder
constituting interest in excess of the Highest Lawful Rate. Without prejudice to
the survival of any other obligations of the Borrower hereunder, the obligations
of the Borrower  under this  Section  2.15 shall  survive for one year after the
termination  of this  Agreement  and/or the payment or  assignment of any of the
Notes.

         2.16 Pro Rata  Treatment.  (a) Each payment or  prepayment of principal
and each  payment of interest  with  respect to a  Competitive  Borrowing  (at a
particular Competitive Bid Rate) or a Committed Borrowing shall be made pro rata
among the Banks in accordance with the respective principal amounts of the Loans
extended by each Bank,  if any,  with respect to such  Competitive  Borrowing or
Committed  Borrowing,  and (b)  refinancings  of Committed  Loans with Committed
Loans of any type,  refinancings of Competitive  Loans with Committed Loans, and
Committed Loans which are not refinancings of other Loans shall be made pro rata
among the Banks in accordance with then respective Commitments.

         2.17 Sharing of Setoffs. Each Bank agrees that if it shall, through the
exercise  of a right of  banker's  lien,  setoff,  or  counterclaim  against the
Borrower,  including,  but not limited to, a secured  claim under Section 506 of
Title 11 of the United States Code or other  security or interest  arising from,
or in lieu of, such secured  claim,  received by such Bank under any  applicable
Debtor Relief Law or otherwise,  obtain payment  (voluntary or  involuntary)  in
respect of the Committed Note held by it (other than pursuant to Section 2.13 or
Section 2.15) as a result of which the unpaid principal portion of the Committed
Note held by it shall be proportionately  less than the unpaid principal portion
of the  Committed  Note  held by any  other  Bank,  it shall be  deemed  to have
simultaneously  purchased from such other Bank a participation  in the Committed
Note held by such other Bank, so that the aggregate  unpaid  principal amount of
the Committed Note and participations in Committed Notes held by each Bank shall
be in the same  proportion  to the  aggregate  unpaid  principal  amount  of all
Committed Notes then  outstanding as the principal  amount of the Committed Note
held by it prior to such exercise of banker's lien,  setoff, or counterclaim was
to the  principal  amount  of all  Committed  Notes  outstanding  prior  to such
exercise of banker's lien, setoff, or counterclaim;  provided,  however, that if
any such  purchase or purchases or  adjustments  shall be made  pursuant to this
Section 2.17 and the payment giving rise thereto shall  thereafter be recovered,
such  purchase or purchases or  adjustments  shall be rescinded to the extent of
such recovery and the purchase  price or prices or adjustment  restored  without
interest.  The Borrower  expressly  consents to the foregoing  arrangements  and
agrees that any


                                     -23-





Bank  holding  a  participation  in a  Committed  Note  deemed  to have  been so
purchased  may, upon the existence of an Event of Default,  exercise any and all
rights of banker's lien,  setoff,  or  counterclaim  with respect to any and all
moneys  owing by the  Borrower  to such Bank as fully as if such Bank had made a
Committed Loan directly to the Borrower in the amount of such participation.

         2.18 Payments.  (a) The Borrower shall make each payment  hereunder and
under any instrument delivered hereunder not later than 1:00 p.m. (Dallas, Texas
time) on the day when due in dollars to the Agent at its address  referred to on
Schedule 1 for the account of the Banks,  in immediately  available  funds.  The
Agent will promptly  thereafter  cause to be distributed  like funds relating to
the payment of principal of or interest on Committed  Loans (other than pursuant
to Section 2.13 and Section 2.15) or Facility Fees ratably to the Banks and like
funds  relating  to  the  payment  of  any  other  amount  (including,   without
limitation, payments of principal or interest on Competitive Loans which are not
made  ratably to the Banks)  payable to any Bank to such Bank for the account of
its Applicable Lending Office, in each case to be applied in accordance with the
terms of this Agreement.

                  (b) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business  Day, such payment shall be made
on the next  succeeding  Business  Day, and such  extension of time shall in all
such cases be  included  in the  computation  of payment of interest or Facility
Fee,  as the case may be;  provided,  however,  if such  extension  would  cause
payment of interest on or principal of a Eurodollar  Loan to be made in the next
following  calendar  month,  such  payment  shall be made on the next  preceding
Business Day.

                  (c)  Unless  the Agent  shall have  received  notice  from the
Borrower  prior to the date on which any  payment is due to the Banks  hereunder
that the Borrower will not make such payment in full,  the Agent may assume that
the  Borrower  has made or will make such  payment  in full to the Agent on such
date  and  the  Agent  may,  in  reliance  upon  such  assumption,  cause  to be
distributed to each Bank on such due date an amount equal to the amount then due
such Bank. If and to the extent the Borrower shall not have so made such payment
in full to the Agent,  each Bank shall  repay to the Agent  forthwith  on demand
such amount  distributed to such Bank together with interest  thereon,  for each
day from the date such  amount is  distributed  to such Bank until the date such
Bank repays such amount to the Agent, at the Federal Funds Effective Rate.

                  (d)  All  payments  (whether  of  principal,  interest,  fees,
reimbursements, or otherwise) by the Borrower under this Agreement shall be made
without setoff or  counterclaim  and shall be made free and clear of and without
deduction  for any  present or future Tax,  levy,  impost,  or any other  charge
against the Borrower,  if any, of any nature whatsoever now or hereafter imposed
by any Tribunal. If the making of such payments by the Borrower is prohibited by
Law unless such a Tax,  levy,  impost,  or other  charge is deducted or withheld
therefrom,  the  Borrower  shall  pay to the  Agent,  on the  date of each  such
payment,  such  additional  amounts  (without  duplication  of any other amounts
required  to be  paid  by the  Borrower  pursuant  to  Section  2.13)  as may be
necessary  in order  that the net  amounts  received  by the  Banks  after  such
deduction or withholding shall equal the amounts



                                    -24-





which  would  have been  received  if such  deduction  or  withholding  were not
required.  The Borrower shall confirm that all applicable Taxes, if any, imposed
on this Agreement or transactions hereunder shall have been properly and legally
paid  by it to the  appropriate  taxing  authorities  by  sending  official  Tax
receipts or notarized  copies of such receipts to the Agent within 30 days after
payment of any applicable Tax.

                  (e) So  long  as no  Event  of  Default  has  occurred  and is
continuing, payments and prepayments of the Obligation shall be applied first to
accrued  interest  then due and payable and to the  remaining  Obligation in the
order and manner as the Borrower  may direct.  At any time during which an Event
of Default has  occurred  and is  continuing  or if the  Borrower  fails to give
direction,  any payment or prepayment  shall be applied in the following  order:
(i) to  expenses  and fees for which  the  Agents  and the  Banks  have not been
reimbursed in accordance  with the Loan Papers;  (ii) to accrued  interest;  and
(iii) to the remaining  Obligation in the order and manner as the Majority Banks
deem appropriate.

         2.19 Calculation of LIBO. The provisions of this Agreement  relating to
calculation  of the LIBO Rate are included  only for the purpose of  determining
the rate of interest or other amounts to be paid  hereunder  that are based upon
such rate,  it being  understood  that each Bank shall be  entitled  to fund and
maintain its funding of all or any part of a Eurodollar Loan as it sees fit. All
such  determinations  hereunder,  however,  shall  be made as if each  Bank  had
actually  funded and  maintained  funding of each  Eurodollar  Loan  through the
purchase in the Eurodollar  InterBank Market of one or more eurodollar  deposits
in an amount  equal to the  principal  amount of such Loan and having a maturity
corresponding to the Interest Period for such Loan.

         2.20 Booking Loans.  Any Bank may make,  carry,  or transfer Loans at,
to, or for the account of any of its branch offices.

         2.21 Quotation of Rates.  It is hereby  acknowledged  that the Borrower
may call the Agent on or before the date on which notice of a Borrowing is to be
delivered by the Borrower in order to receive an indication of the rate or rates
then in effect,  but that such projection shall not be binding upon the Agent or
any Bank nor affect the rate of interest which  thereafter is actually in effect
when the election is made.

     SECTION 3. REPRESENTATIONS AND WARRANTIES. The Borrower represents and
warrants to the Agents and the Banks as follows:

         3.1 Purpose of Credit  Facility.  The Borrower  will use Loan  proceeds
only for working capital and general  corporate  purposes of the Companies.  The
proceeds  loaned  hereunder  will not be used  directly  or  indirectly  for the
purpose of  purchasing  or carrying,  or for the purpose of extending  credit to
others for the purpose of purchasing or carrying any "margin stock" as that term
is defined in Regulation G, T, U, or X of the Board, as amended, or to repay any
Debt which was created for such purposes.

          3.2 Corporate Existence, Good Standing, and Authority. Each Company
is, to the best of the Borrower's knowledge, duly organized, validly existing,
and in good standing



                                      -25-





under  the  Laws  of  its  state  of  incorporation  (such  jurisdictions  being
identified on Exhibit 21 of Borrower's  most recent annual report filed with the
Securities and Exchange  Commission on Form 10K). Except where failure would not
reasonably be expected to have a Material  Adverse  Effect,  each Company (a) is
duly  qualified  to  transact  business  and is in good  standing  as a  foreign
corporation in each jurisdiction where the nature and extent of its business and
properties  require the same and (b) possesses all requisite  authority,  power,
licenses, permits, and franchises to conduct its business as is now being, or is
contemplated  herein to be,  conducted.  The Borrower  possesses  all  requisite
authority,  power,  licenses,  permits, and franchises to execute,  deliver, and
comply with the terms of the Loan  Papers,  all which have been duly  authorized
and approved by all necessary  corporate  action and, except where failure would
not  reasonably  be expected  to have a Material  Adverse  Effect,  for which no
approval or consent of any Person or  Tribunal  is  required  which has not been
obtained  and no filing or other  notification  to any  Person  or  Tribunal  is
required which has not been properly completed.

         3.3  Subsidiaries.  Exhibit 21 of the  Borrower's  most  recent  annual
report filed with the Securities and Exchange Commission on Form 10K sets forth,
in  all  material  respects,  all  existing  Subsidiaries  of the  Borrower  and
correctly lists, as to each Subsidiary, (a) its name and (b) its jurisdiction of
incorporation.  The  shares of  capital  stock of each  Subsidiary  owned by the
Borrower  (either  directly or indirectly  through another  Subsidiary),  as set
forth on Exhibit 21 of the  Borrower's  most recent annual report filed with the
Securities and Exchange Commission on Form 10K, are the duly authorized, validly
issued, fully paid, and nonassessable shares of such Subsidiary and are owned by
the Borrower free and clear of all Liens except Permitted Liens.

         3.4  Financial  Statements.  The Current  Financials  were  prepared in
accordance with GAAP and present fairly the consolidated financial condition and
the results of operations of the Company as of, and for the periods  ended,  the
dates  thereof.  There  were no  material  (to the  Companies  taken as a whole)
liabilities,  direct or indirect, fixed or contingent,  of any Company as of the
date of the Current Financials which are not reflected therein.  There have been
no changes in the  consolidated  financial  condition of the Companies from that
shown in the Current  Financials  between  such dates and the date hereof  which
could reasonably be expected to have a Material  Adverse Effect.  No Company has
incurred any material (to the Companies taken as a whole)  liability,  direct or
indirect,  fixed or contingent,  between the dates of the Current Financials and
the  date  hereof,  except  in the  ordinary  course  of  business,  such  as in
connection with acquisitions and financing activities.

         3.5 Compliance with Laws, Charter,  and Agreements.  No Company is, nor
will the  execution,  delivery,  performance,  or  observance of the Loan Papers
cause any Company to be, in violation of any Laws or any Material  Agreements to
which it is a party,  other than such  violations  which would not reasonably be
expected  to have a  Material  Adverse  Effect.  Neither  the  Borrower  nor any
Significant  Subsidiary is, nor will the execution,  delivery,  performance,  or
observance of the Loan Papers cause the Borrower or any  Significant  Subsidiary
to be, in violation of its bylaws or charter.



                                      -26-





         3.6  Litigation.  Except  as  described  on  Schedule  3.6  and  to the
knowledge of the Borrower, no Company is aware of any "Material" Litigation, and
there are no Material  outstanding  or unpaid  judgments  against  any  Company.
Material for purpose of this Section 3.6 in relation to Litigation would include
any actions or proceedings  pending or threatened against any Company before any
court or Tribunal seeking damages,  net of insurance proceeds to the Company, in
excess  of  $1,000,000  in any  case  or 1% of  Consolidated  Net  Worth  in the
aggregate, or which might result in any Material Adverse Effect.

         3.7 Taxes.  All returns of each Company  required to be filed have been
filed (or extensions  have been granted) except where the failure to do so could
not  reasonably  be expected to have a Material  Adverse  Effect,  and all Taxes
imposed  upon each  Company  which are due and payable have been paid other than
Taxes for which the criteria for Permitted Liens have been satisfied.

         3.8  Environmental  Matters.  No  Company's  ownership  of  its  assets
violates any  applicable  Environmental  Law, other than such  violations  which
would not  reasonably  be expected  to have a Material  Adverse  Effect.  To the
Borrower's knowledge, no investigation or review is pending or threatened by any
Tribunal  with  respect to any alleged  violation  of any  Environmental  Law in
connection  with any Company's  assets.  None of any Company's  assets have been
used by such Company or, to the Borrower's knowledge, any other Person as a dump
site for any Hazardous Substance.

         3.9 Employee  Benefit Plans. (a) No employee benefit plan as defined in
the Code  and  Title IV of ERISA of any  Company  has  incurred  an  accumulated
funding  deficiency in an amount  sufficient to have a Material  Adverse Effect,
(b) no Company has incurred  material  liability to the PBGC in connection  with
any  such  plan,  (c)  no  Company  has  withdrawn  in  whole  or in  part  from
participation  in a  Multiemployer  Plan,  and (d) to the best of the Borrower's
knowledge,  no "prohibited  transaction"  (as defined in section 406 of ERISA or
section 4975 of the Code) or  "reportable  event" (as defined in section 4043 of
ERISA) has  occurred  which  could  reasonably  be  expected  to have a Material
Adverse Effect.

         3.10 Properties;  Liens.  Each Company has good and marketable  (except
for  Permitted  Liens)  title  to all  its  property  reflected  on the  Current
Financials  (except  for  dispositions  of property  in the  ordinary  course of
business  between  the date or dates  thereof and the date  hereof).  Except for
Permitted  Liens,  there  is no Lien on any  property  of any  Company,  and the
execution,  delivery,  performance,  or  observance  of the Loan Papers will not
require or result in the creation of any Lien other than Permitted Liens.

         3.11 Holding Company and Investment Company Status. The Borrower is not
(a) a "holding  company,"  a  "subsidiary  company" of a "holding  company,"  an
"affiliate"  of a "holding  company" or of a "subsidiary  company" of a "holding
company," or a "public utility" within the meaning of the Public Utility Holding
Company Act of 1935, as amended,  (b) a "public  utility"  within the meaning of
the Federal  Power Act,  as  amended,  (c) an  "investment  company"  within the
meaning of the  Investment  Company Act of 1940, as amended,  (d) an "investment
adviser" within the meaning of the Investment Advisers Act of


                                     -27-





1940,  as  amended,   or  (e)  subject  to  the   jurisdiction  of  the  Federal
Communications Commission or any public service commission.

         3.12  Transactions  with  Affiliates.  Except as  disclosed on Schedule
3.12, no Company is a party to a material transaction with any of its Affiliates
other than  transactions  in the  ordinary  course of business and upon fair and
reasonable terms not materially less favorable than such Company could obtain or
could become entitled to in an arm's-length  transaction  with a Person that was
not its  Affiliate.  For purposes of this Section 3.12,  such  transactions  are
"material" if they, individually or in the aggregate, require any Company to pay
more  than 1  percent  of  Consolidated  Net  Worth  over  the  course  of  such
transactions.

         3.13 Leases.  All material  leases under which any Company is lessee or
tenant are in full force and effect,  and no default or potential default exists
thereunder, the effect of which would have a Material Adverse Effect.

         3.14  Labor  Matters.  There  are  no  actual  or,  to  the  Borrower's
knowledge,  threatened strikes,  labor disputes,  slow downs, walkouts, or other
concerted interruptions of operations by any Company's employees,  the effect of
which would have a Material Adverse Effect.

         3.15 Insurance. Each Company maintains with financially sound insurance
companies or associations (or, as to workers' compensation or similar insurance,
with an insurance fund or by  self-insurance  authorized by the jurisdictions in
which it operates)  insurance  concerning its properties and businesses  against
such  casualties  and  contingencies  and of such types and in such amounts (and
with  co-insurance  and  deductibles)  as is  customary  in the  case of same or
similar  businesses;  provided,  however,  a program of  self-insurance  in such
amounts  and such risks as are  prudent and which is  consistent  with  accepted
business practice shall constitute compliance with this Section 3.15.

         3.16     Solvency.  The Companies are, and after giving effect to the
transactions contemplated under the Loan Papers will be, solvent.

         3.17     Business.  The business of the Borrower, as presently
conducted and as proposed to be conducted, is set forth on Schedule 3.17.

         3.18     General.  There is no material  fact or condition  relating
to the Loan Papers or the  financial  condition and business of any Company 
which could reasonably be expected to have a Material  Adverse Effect and which
has not been related, in writing, to the Agent, other than industry-wide risks
in the ordinary course of business  associated with the types of business
conducted by any Company. All writings exhibited or delivered to the Agent by
or on behalf of any  Company  are and will be genuine  and in all  material
respects  what they purport and appear to be.




                                 -28-





SECTION 4.                 CONDITIONS PRECEDENT.

         4.1      Initial Loan.  No Bank will be obligated to fund the initial
Loan unless the Agent has received all of the following in form and substance
satisfactory to the Agent and its special counsel:

                  (a)      Loan Papers.  This Agreement, the Notes, a Notice of
Committed Borrowing or a Competitive Bid Request, and the Current Financials.

                  (b) Officers' Certificates. A certificate dated as of the date
         hereof,  executed and  delivered by the Borrower,  certifying  that (i)
         attached is a true,  correct,  and complete copy of (A) the  Borrower's
         charter,  certified by the appropriate state official and dated no more
         than ten (10) days prior to the date hereof, (B) the Borrower's bylaws,
         and (C)  resolutions of the Borrower's  board of directors  authorizing
         the  execution and delivery of each Loan Paper to which the Borrower is
         a party and (ii) the officers whose specimen  signatures appear on such

         4.2 Each Loan. In addition, the Banks will not be obligated to fund any
Loan unless at the time of such funding (a) the  representations  and warranties
made in the Loan Papers (other than,  after the initial Loan, those contained in
the penultimate  sentence of Section 3.4 and the first sentence of Section 3.18)
are true and correct in all material respects (except to the extent that (i) the
representations  and  warranties  speak to a specific  date or (ii) the facts on
which  such  representations  and  warranties  are based  have been  changed  by
transactions  contemplated  or permitted by this  Agreement),  (b) no Default or
Event of Default shall have occurred and shall be continuing, (c) the funding of
such Loan is  permitted by Law and (d) if requested by the Agent or the Majority

                                 -29-






         4.3      Materiality of Conditions.  Each condition precedent herein 
is material to the transactions contemplated herein, and time is of the essence
in respect of each thereof.

         4.4     Waiver of Conditions. Subject to the provisions of Section
9.15, the Majority Banks may elect to fund any Loan without all conditions being
satisfied, but this shall not be deemed to be a waiver of the requirement that
each such condition precedent be satisfied as a prerequisite for any subsequent
Loan, unless the Majority Banks (or, if required by Section 9.15, all Banks)
specifically waive each such item in writing.

SECTION 5.  COVENANTS.  So long as the Banks are  committed  to make Loans under
this  Agreement  and  thereafter  until the  Obligation is paid and performed in
full,  unless the  Borrower  receives a prior  written  notice from the Majority
Banks (or, if required by Section 9.15,  all Banks) that they do not object to a
deviation,  the Borrower  covenants  and agrees with the Agents and the Banks as
follows:

         5.1      Use of Proceeds.  Proceeds advanced hereunder shall be used
only as represented herein.

         5.2      Books and Records.  Each Company shall keep, in accordance

                  (a)  Promptly  after  preparation,  and no later than 120 days
         after  the  last day of each  fiscal  year of the  Borrower,  Financial

         operations of the Companies as of, and for the year ended on, such last
         day,  accompanied  by (i) the  opinion  of KPMG Peat  Marwick  Main (or
         another  firm of  nationally-recognized  independent  certified  public
         accountants reasonably acceptable to Majority Banks), based on an audit
         using  generally  accepted  auditing  standards,  that  such  Financial
         Statements were prepared in accordance with GAAP and present fairly the
         consolidated  financial  condition  and  results of  operations  of the
         Companies  (and  such  accountants  shall  indicate  in a letter to the
         Agent,  that  during  their  audit no Default  or Event of Default  not
         already reported was discovered or, if such Default or Event of Default
         was discovered,  the nature and period of existence thereof) and (ii) a
         Financial Report Certificate with respect to such Financial Statements.

                  (b)  Promptly  after  preparation,  and no later  than 60 days

         and for the period from the  beginning  of the current  fiscal year to,
         such last day, and (ii) a Financial Report  Certificate with respect to
         such Financial Statements.

                  (c) Promptly after preparation (and no later than the later of
         15 days (a) after such  filing is due or (b) after  timely  filing,  if
         filed with the Securities and Exchange Commission),  true copies of all
         regular and periodic reports,  statements,  documents, plans, and other
         written  communications  furnished  by or on behalf of any  Company  to
         stockholders  or to the  Securities and Exchange  Commission.  However,
         only  registration  statements  covering  more  than 2  percent  of the
         Borrower's  outstanding  shares of common stock shall be required to be
         furnished unless specifically requested by the Agent.

                  (d)  Promptly  upon  receipt  thereof,  copies of any  notices

         regulatory agencies) relating to the possible violation or violation of
         any Law which might  materially  and adversely  affect the  franchises,
         permits, or rights for the operation of the business of any Company.

                  (e) Notice, promptly after the Borrower knows or has reason to
         know of, (i) the  existence  of any Material  Litigation  as defined in
         Section  3.6,  (ii)  any  material  change  in  any  material  fact  or
         circumstance  represented  or warranted  in any Loan Paper,  or (iii) a
         Default or Event of  Default,  specifying  the nature  thereof and what
         action the  Borrower  or any other  Company  has taken,  is taking,  or
         proposes to take with respect thereto.

                  (f)  Promptly  upon  the  Agent's  reasonable  request,   such
         information  (not  otherwise  required to be  furnished  under the Loan
         Papers) respecting the business affairs, assets, and liabilities of any
         Company, and any opinions,  certifications,  and documents, in addition
         to those mentioned herein.

         5.4 Inspection.  The Borrower shall allow the Agent and each Bank, when
the Agent or such Bank reasonably deems necessary, at such Bank's own expense if
no Default then exists,  to inspect any of its  properties,  to review  reports,
files,  and other records and to make and take away copies  thereof,  to conduct
tests or  investigations,  and to discuss any of its  affairs,  conditions,  and
finances  with any director,  officer,  or employee of such Company from time to
time, upon reasonable notice during reasonable business hours, or otherwise when
reasonably considered necessary.

         5.5 Taxes.  Each Company shall promptly pay when due any Taxes,  except
those which if unpaid  would not cause a Material  Adverse  Effect and Taxes for
which the criteria for Permitted Liens have been satisfied. No Company shall use
any proceeds of Loans to pay the wages of employees  unless a timely  payment to
or deposit  with the United  States of America of all amounts of Tax required to
be deducted and withheld with respect to such wages is also made.

         5.6 Payment of  Obligations.  Each Company shall promptly pay (or renew
and  extend) all of its  material  obligations  as the same  become due,  but no
Company will make any  voluntary  prepayment  of the principal of any Debt other
than the Obligation,  whether subordinate to the Obligation or not, if a Default
or Event of Default exists under any Loan Paper.



                                        -31-






         5.7 Expenses of Agent.  The Borrower  shall promptly pay all reasonable
and necessary  out-of-pocket  costs,  fees, and expenses paid or incurred by the
Agent incident to any Loan Paper (including,  but not limited to, the reasonable
fees and expenses of counsel to the Agent in  connection  with the  negotiation,
preparation,  delivery,  and  execution  of the  Loan  Papers  and  any  related
amendment,  waiver,  or consent) or to the enforcement of the obligations of any
Company or the exercise of any Rights (including, but not limited to, reasonable
attorneys'  fees  and  court  costs),  all  of  which  shall  be a  part  of the
Obligation.

         5.8 Maintenance of Existence,  Assets, Business, and Insurance.  Except
as permitted by Section  5.12,  each  Company  shall at all times:  Maintain its

jurisdiction of incorporation or organization and all other  jurisdictions where
the  failure to so  maintain  could  reasonably  be  expected to have a Material
Adverse Effect; maintain all licenses, permits, and franchises necessary for its
business,  where the failure to so maintain could reasonably be expected to have
a Material  Adverse  Effect;  keep all of its assets which are  necessary to its
business in good working order and condition  (ordinary wear and tear excepted),
and make all necessary repairs and replacements thereto; and maintain either (a)
insurance with such insurers, in such amounts, and covering such risks, as shall
be ordinary and  customary  in the  industry or (b) a comparable  self-insurance
program.

         5.9 Preservation  and Protection of Rights.  Each Company shall perform
such acts and duly authorize,  execute,  acknowledge,  deliver, file, and record
any additional agreements, documents, instruments, and certificates as the Agent
may  reasonably  deem  necessary or appropriate in order to preserve and protect
the Rights of the Agents or the Banks under any Loan Paper.

         5.10 Employee  Benefit Plans. No Company will,  directly or indirectly,
if it would  have a  Material  Adverse  Effect,  (a)  engage in any  "prohibited
transaction"  (as defined in section 406 of ERISA or section  4975 of the Code),
(b) permit the funding  requirements  under ERISA with  respect to any  employee
benefit plan  established  or maintained by any Company to ever be less than the
minimum  required by ERISA,  (c) permit any employee benefit plan established or
maintained  by any  Company  to  ever  be  subject  to  involuntary  termination
proceedings, or (d) fully or partially withdraw from any Multiemployer Plan.

         5.11 Liens.  No Company will create,  incur,  or suffer or permit to be
created or incurred or to exist any Lien (other than  Permitted  Liens) upon any
of its assets.

         5.12 Acquisitions,  Mergers, and Dissolutions. No Company will merge or
consolidate with any Person other than any merger or  consolidation  whereby the
Borrower (or another  Company,  if the  Borrower is not a party  thereto) is the
surviving  corporation and immediately after such merger or consolidation  there
shall not exist any Default or Event of Default.

         5.13     Loans, Advances, and Investments.  Except as permitted by
Section 5.12, no Company will make any loan, Guaranties, advance, extension of
credit, or capital contribution to, make any investment in, or purchase or

(as shown on such Person's most recently published statement of condition), and,
unless  Borrower has a written  commitment to borrow funds from such  commercial
bank,  which  certificates  of deposit have one of the two highest  ratings from
Moody's  Investors  Service,  Inc.,  or  Standard & Poor's  Ratings  Group;  (e)

ownership  interest in such Person or (y) secured by the borrower's  interest in
such  business;  (k) in the ordinary  course of business and  investments in the
capital stock of the Rural Telephone Bank,  National Bank for  Cooperatives,  or

of this Section 5.14, such transactions are "material" if



                                    -33-





they,  individually or in the aggregate,  require any Company to pay more than 1

the exchange of assets -- other than equipment -- for similar assets of equal or

by all Companies, do not exceed 10 percent of Consolidated Net Worth.

         5.16  Compliance  with Laws and Documents.  No Company will violate the
provisions of any laws or any Material  Agreement if such  violation  alone,  or
when aggregated with all other such violations,  could reasonably be expected to
have a Material  Adverse  Effect.  No Company will violate the provisions of its
charter or bylaws or modify,  repeal,  replace,  or amend any  provision  of its
charter or bylaws if such action could reasonably be expected to have a Material
Adverse  Effect.  The Borrower will provide to the Agent a copy of each document

1935, as amended, (b) a "public utility" within the meaning of the Federal Power
Act,  as  amended,  (c)  an  "investment  company"  within  the  meaning  of the
Investment  Company Act of 1940,  as  amended,  or (d) an  "investment  adviser"

         5.21 Environmental  Laws. Each Company shall conduct its business so as
to  comply  with all  applicable  Environmental  laws and  shall  promptly  take
corrective  action to remedy  any  non-compliance  with any  Environmental  Law,
except where  failure to so comply or take such action would not  reasonably  be
expected to have a Material Adverse Effect. Each Company shall maintain a system
which, in its reasonable business judgment, will assure its continued compliance
with Environmental Laws.

         5.22 Environmental Indemnification.  Borrower shall indemnify, protect,
and  hold  each  Indemnified  Party  harmless  from  and  against  any  and  all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims,  proceedings,   costs,  expenses  (including,  without  limitation,  all
reasonable  attorneys' fees and legal expenses  whether or not suit is brought),
and  disbursements  of any kind or  nature  whatsoever  which may at any time be
imposed on,  incurred by, or asserted  against such  Indemnified  Parties,  with
respect to or as a direct or indirect  result of the violation by any Company of
any  Environmental  Law; or with respect to or as a direct or indirect result of
any Company's generation, manufacture,  production, storage, release, threatened
release, discharge,  disposal or presence in connection with its properties of a
Hazardous Substance including,  without limitation,  (a) all damages of any such
use, generation, manufacture,  production, storage, release, threatened release,
discharge,  disposal, or presence, or (b) the costs of any required or necessary
environmental investigation,  monitoring, repair, cleanup, or detoxification and
the preparation and implementation of any closure, remedial, or other plans. The
provisions of and undertakings and  indemnification  set forth in this paragraph
shall survive the  satisfaction and payment of the Obligation and termination of
this  Agreement for a period of time set forth in the statute of  limitations in
any applicable Environmental Law.

         5.23 Ratio of Funded  Debt to Net Worth.  As  calculated  at the end of
each fiscal  quarter of the Borrower,  the Borrower  shall not permit (a) Funded
Debt of the  Companies  to exceed 185% of  Consolidated  Net Worth or (b) Funded
Debt of the Companies other than the Borrower to exceed 150% of Consolidated Net
Worth (excluding Borrower's portion thereof). For purposes of this Section 5.23,
Funded Debt shall  include any  Company's  Guaranty of Funded Debt of any Person
other than another Company or the Borrower's Employee Stock Ownership Plan.

         5.24 Ratio of EBIT to Interest  Expense and Preferred Stock  Dividends.
As  calculated  at the end of each fiscal  quarter of the Borrower (but computed
for the four fiscal quarters ending on the last day of such fiscal quarter), the
Borrower  shall not permit EBIT of the Companies to be less than 150% of the sum
of (a) consolidated interest expense of the Companies and (b) dividends declared
or paid by any Company (other than to another Company) on its preferred  capital
stock (but if such  dividends  are  declared  and paid during such  four-quarter
period, the amount shall not be counted twice).

         5.25 Tax  Consolidation.  If the Borrower is acquired by another Person
and,  as a result of such  acquisition,  the  Borrower or the  Borrower  and any
Subsidiary  becomes an  "includible  corporation"  within the meaning of section
1504(b)  of the Code and files a  consolidated  federal  income  tax return as a
member of an "affiliated  group" of  corporations  within the meaning of section
1504(a) of the Code, the Borrower shall require the parent


                                -35-





corporation  of the  affiliated  group to enter into an  agreement  which  shall
provide that if the Borrower or such Subsidiary  shall sustain any loss that may
be applied to reduce the consolidated  taxable income of the affiliated group of
which the Borrower or the Borrower and such Subsidiary is or was a member,  such
parent corporation will pay, or cause all corporations  (other than the Borrower
and the Subsidiaries) which were members of the affiliated group for the year in
which such loss is applied to pay, to the  Borrower or such  Subsidiary,  as the
case may be,  promptly after filing the  consolidated  federal income tax return
for such taxable  year,  an amount  equal to the excess of (i) the  consolidated
federal  income tax liability of the  affiliated  group for such year,  computed
without reducing the consolidated  taxable income of such group by the amount of
the Borrower's or such  Subsidiary's  loss, over (ii) the  consolidated  federal
income tax  liability  of such group for such year  computed  by  including  the
Borrower's or such  Subsidiary's  loss in consolidated  taxable  income.  If any
corporation  (other than the Borrower or a Subsidiary) which is a member of such
affiliated group shall sustain any such loss in a taxable year, the Borrower and
each Subsidiary  which is or was a member of such affiliated group for such year
may agree to pay to the member  sustaining  such  loss,  or to pay to the parent
corporation of such affiliated group for distribution to such member,  an amount
equal to the excess of (i) the  consolidated  federal income tax liability which
the Borrower and said  Subsidiaries  would have  incurred for such year, if such
liability had been computed on a basis which was not consolidated with the other
members  of such  affiliated  group,  over (ii) the  total  federal  income  tax
liability  (taking into account such member's  loss) which the Borrower and said
Subsidiaries actually were required to pay for such year.

SECTION  6.  DEFAULT.  The term  "Event of  Default"  means the  occurrence  and
continuance of any one or more of the following events (including the passage of
time, if any, specified  therefor)  (provided that, if any such event occurs and
the Banks or Majority  Banks,  as required by the  provisions  of Section  9.15,
subsequently agree in writing that they will not exercise any remedies hereunder
as a result  thereof,  the  occurrence  and  continuance  of such event shall no
longer be deemed an Event of  Default  hereunder  insofar  as the state of facts
giving rise to such event is concerned):

         6.1 Payment of  Obligation.  The failure or refusal of the  Borrower to
pay any portion of the Obligation, as the same become due in accordance with the
terms of the Loan Papers and, in the case of an interest  payment,  such failure
or refusal  continues  for a period of 5 Business  Days (no grace  period  being
given for failure or refusal to make a principal  payment).  Notwithstanding the
foregoing,  the  Borrower's  failure to pay, if caused solely by a wire transfer
malfunction  or similar  problem  outside the Borrower's  control,  shall not be
deemed an Event of Default.

         6.2      Covenants.

                  (a)  The  failure  or  refusal  of  the  Borrower   (and,   if
         applicable,  any other  Company) to  punctually  and properly  perform,
         observe,  and  comply  with  any  covenant,   agreement,  or  condition
         contained in Sections 5.11,  5.12,  5.14, 5.17, 5.18, 5.19, 5.20, 5.23,
         and 5.24.



                                     -36-





                  (b)  The  failure  or  refusal  of  the  Borrower   (and,   if
         applicable,  any other  Company) to  punctually  and properly  perform,
         observe,  and  comply  with  any  covenant,   agreement,  or  condition
         contained  in any of the Loan Papers to which such  Company is a party,
         other than covenants to pay the Obligation and the covenants  listed in
         clause (a) preceding, and such failure or refusal continues for 10 days
         after notice from the Agent to the Borrower.

         6.3 Debtor Relief.  The Companies shall not be Solvent,  or any Company
(a) fails to pay its Debts generally as they become due, (b) voluntarily  seeks,
consents  to, or  acquiesces  in the  benefit of any Debtor  Relief  Law, or (c)
becomes a party to or is made the subject of any proceeding  provided for by any
Debtor Relief Law,  other than as a creditor or claimant,  that could suspend or
otherwise  adversely affect the Rights of the Agents or the Banks granted in the
Loan Papers (unless,  in the event such proceeding is involuntary,  the petition
instituting same is dismissed within 60 days after its filing).

         6.4 Attachment. The failure of any Company to have discharged within 60
days after  commencement any attachment,  sequestration,  or similar  proceeding
which,  individually or together with all such other  proceedings  then pending,
affects assets of such Company having a value  (individually or collectively) of
1 percent of Consolidated Net Worth or more.

         6.5 Payment of  Judgments.  Any Company  fails to pay any  judgments or
orders for the payment of money in excess of 1 percent of Consolidated Net Worth
(individually  or  collectively)  rendered  against  it or any of its assets and
either (a) any enforcement proceedings shall have been commenced by any creditor
upon  any  such  judgment  or  order  or (b) a stay of  enforcement  of any such
judgment or order,  by reason of pending  appeal or  otherwise,  shall not be in
effect  prior  to the time its  assets  may be  lawfully  sold to  satisfy  such
judgment.

         6.6 Default Under Other Agreements. A default exists under any Material
Agreement to which any Company is a party,  the effect of which is to cause,  or
which permits the holder thereof (or a trustee or representative of such holder)
to cause,  unpaid  consideration of at least 1 percent of Consolidated Net Worth
(individually or in the aggregate) to become due prior to the stated maturity or
prior to the regularly scheduled dates of payment.

         6.7 Antitrust  Proceedings.  A petition or complaint is filed before or
by any Tribunal  (including,  without limitation,  the Federal Trade Commission,
the United States Justice Department, or the Federal Communications  Commission)
seeking to cause the Borrower or any Subsidiary to divest a significant  portion
of its assets or any of its Subsidiaries pursuant to any antitrust, restraint of
trade,  unfair  competition,  or similar laws, and such petition or complaint is
not dismissed or discharged within 270 days after the filing thereof.

         6.8  Misrepresentation.  Either  Agent or any Bank  discovers  that any
statement, representation, or warranty in the Loan Papers, other than, after the
initial Loan, those contained in the penultimate sentence of Section 3.4 and the
first sentence of Section 3.18,


                                   -37-





any Financial Statement of the Borrower, or any writing ever delivered to either
Agent or any Bank pursuant to the Loan Papers is false, misleading, or erroneous
when made or delivered in any material respect.

SECTION 7.                 RIGHTS AND REMEDIES.

         7.1      Remedies Upon Event of Default.

                  (a) Should an Event of Default occur and be  continuing  under
         Section  6.3,  the   commitment  of  the  Banks  to  make  Loans  shall
         automatically terminate and the entire unpaid balance of the Obligation
         shall  automatically  become due and payable  without any action of any
         kind whatsoever.

                  (b) Should any other Event of Default occur and be continuing,
         subject to any agreement among the Banks, the Agent may (and shall upon
         the request of the Majority  Banks),  at its (or the  Majority  Banks')
         election,  do any one or more of the following:  (i) If the maturity of
         the Obligation has not already been  accelerated  under Section 7.1(a),
         declare  the  entire  unpaid  balance  of the  Obligation,  or any part
         thereof,  immediately  due and  payable,  whereupon it shall be due and
         payable  (and  notice  of such  declaration  shall  promptly  be  given
         thereafter by the Agent to the Borrower); (ii) terminate commitments to
         make Loans hereunder; (iii) reduce any claim to judgment; (iv) exercise
         (or  request  each Bank to  exercise)  the Rights of offset or banker's
         Lien against the  interest of the Borrower in and to every  account and
         other  property of the Borrower which are in the possession of any Bank
         to the extent of the full amount of the  Obligation;  and (v)  exercise
         any and all  other  legal  or  equitable  Rights  afforded  by the Loan
         Papers, the laws of the State of Texas or any other jurisdiction as the
         Agent shall deem appropriate, or otherwise,  including, but not limited
         to, the Right to bring suit or other  proceedings  before any  Tribunal
         either for specific  performance of any covenant or condition contained
         in any of the  Loan  Papers  or in  aid of the  exercise  of any  Right
         granted to the Banks in any of the Loan Papers.

         7.2 Waivers.  The Borrower  hereby  waives  presentment  and demand for
payment, protest, notice of intention to accelerate, notice of acceleration, and
notice of protest and nonpayment,  and agrees that its liability with respect to
the  Obligation,  or any part  thereof,  shall not be affected by any renewal or
extension in the time of payment of the Obligation, by any indulgence, or by any
release or change in any security for the payment of the Obligation.

         7.3  Performance by Agent.  If any covenant,  duty, or agreement of any
Company is not  performed in accordance  with the terms of the Loan Papers,  the
Agent may, at its option (but subject to the  approval of the  Majority  Banks),
perform or attempt to perform  such  covenant,  duty,  or agreement on behalf of
such  Company.  In  such  event,  any  amount  expended  by the  Agent  in  such
performance  or  attempted  performance  shall  be  reasonable,  payable  by the
Borrower to the Agent on demand, shall become part of the Obligation,  and shall
bear interest at the Default Rate from the date of such expenditure by the Agent
until


                                     -38-





paid.  Notwithstanding the foregoing,  it is expressly understood that the Agent
does not assume and shall never have, except by its express written consent, any
liability or  responsibility  for the  performance  of any  covenant,  duty,  or
agreement of any Company.

         7.4  Delegation  of Duties  and  Rights.  The  Agents and the Banks may
perform  any of their  duties or  exercise  any of their  Rights  under the Loan
Papers by or through  the Agent and their and the Agent's  officers,  directors,
employees, attorneys, agents, or other representatives.

         7.5 Banks Not in Control.  None of the  covenants  or other  provisions
contained in this Agreement or in any other Loan Paper shall, or shall be deemed
to, give the Agents or the Banks the Right to exercise  control  over the assets
(including,  without limitation,  real property),  affairs, or management of any
Company,  the power of the  Agents and the Banks  being  limited to the Right to
exercise the remedies provided in this Section 7.

         7.6 Waivers by Banks.  The acceptance by the Agents or the Banks at any
time and from time to time of  partial  payment on the  Obligation  shall not be
deemed to be a waiver of any Event of Default  then  existing.  No waiver by the
Agents, the Majority Banks, or all of the Banks of any Event of Default shall be
deemed to be a waiver of any other then-existing or subsequent Event of Default.
No delay or omission by the Agents,  the Majority  Banks, or all of the Banks in
exercising  any Right  under  the Loan  Papers  shall  impair  such  Right or be
construed as a waiver thereof or any acquiescence  therein, nor shall any single
or  partial  exercise  of any such  Right  preclude  other or  further  exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

         7.7 Cumulative Rights. All Rights available to the Agents and the Banks
under the Loan Papers are  cumulative  of and in  addition  to all other  Rights
granted  to the  Agents  and the Banks at law or in  equity,  whether or not the
Obligation  is due and  payable  and whether or not the Agents or the Banks have
instituted any suit for collection,  foreclosure,  or other action in connection
with the Loan Papers.

         7.8 Application of Proceeds.  Any and all proceeds ever received by the
Agents or the Banks from the exercise of any Rights pertaining to the Obligation
shall be applied to the Obligations in the order and manner set forth in Section
2.18.

         7.9 Certain Proceedings. The Borrower will promptly execute and deliver
or  cause  the  execution  and  delivery  of,  all  applications,  certificates,
instruments,  registration  statements,  and all other  documents and papers the
Agents or the Banks may reasonably  request in connection  with the obtaining of
any  consent,  approval,  registration,   qualification,   permit,  license,  or
authorization of any other Tribunal or other Person necessary or appropriate for
the effective exercise of any Rights under the Loan Papers. Because the Borrower
agrees  that the  Agents'  and the  Banks'  remedies  at law for  failure of the
Borrower to comply with the provisions of this paragraph would be inadequate and
that such failure would not be adequately  compensable in damages,  the Borrower
agrees that the covenants of this paragraph may be specifically enforced.



                                   -39-





SECTION 8.                 AGREEMENT AMONG BANKS.

         8.1      Agents.

                  (a) Each Bank hereby  irrevocably  appoints and authorizes the
Agents to act on its behalf and to exercise such powers under this  Agreement as
are  specifically  delegated  to or required of such Agent by the terms  hereto,
together  with  such  powers as are  reasonably  incidental  thereto.  As to any
matters not expressly  provided for by this  Agreement or the Notes  (including,
without  limitation,  enforcement or collection of the Notes),  the Agents shall
not be required  to exercise  any  discretion  or take any action,  but shall be
required to act or to refrain  from acting (and shall be fully  protected  in so
acting or refraining  from acting) upon the  instructions of the Majority Banks,
and such instructions  shall be binding upon all Banks and all holders of Notes;
provided, however, that neither Agent shall be required to take any action which
exposes such Agent to personal  liability or which is contrary to this Agreement
or applicable law.

                  (b) The Agent may resign at any time by giving  written notice
thereof to the Banks, the Auction Administration Agent, and the Borrower and may
be removed  as the Agent  under  this  Agreement  and the Notes at any time with
cause by all Banks other than the Agent (the  "Removing  Banks").  Upon any such
resignation  or  removal,  the  Majority  Banks  shall have the right,  with the
consent of the Borrower, not to be unreasonably withheld, to appoint a successor
Agent from among the Banks  (other than the  resigning  Agent).  If no successor
Agent  shall  have been so  appointed  by the  Majority  Banks,  and shall  have
accepted such  appointment,  within 30 calendar days after the retiring  Agent's
giving  notice of  resignation  or the Removing  Banks'  removal of the retiring
Agent,  then the retiring Agent may, on behalf of the Banks, with the consent of
the Borrower, not to be unreasonably withheld,  appoint a successor Agent, which
shall be a  commercial  bank  organized  under the laws of the United  States of
America or of any state thereof and having a combined  capital and surplus of at
least  $100,000,000.  Upon  the  acceptance  of any  appointment  as  the  Agent
hereunder and under the Notes by a successor  Agent,  such successor Agent shall
thereupon succeed to and become vested with all rights,  powers,  privileges and
duties of the retiring  Agent,  and the retiring Agent shall be discharged  from
its  duties  and  obligations  under this  Agreement  and the  Notes.  After any
retiring  Agent's  resignation  or removal as the Agent  hereunder and under the
Notes,  the  provisions  of this  Section 8 shall inure to its benefit as to any
actions  taken or  omitted  to be taken by it while it was the Agent  under this
Agreement and the Notes.

                  (c) The Auction Administration Agent may resign at any time by
giving written notice thereof to the Banks,  the Agent, and the Borrower and may
be removed as the  Auction  Administration  Agent under this  Agreement  and the
Notes at any time with cause by all Banks other than the Auction  Administrative
Agent (the "AAA Removing  Banks").  Upon any such  resignation  or removal,  the
Majority Banks shall have the right, with the consent of the Borrower, not to be
unreasonably  withheld, to appoint a successor Auction  Administration Agent. If
no successor  Auction  Administration  Agent shall have been so appointed by the
Majority  Banks,  and shall have accepted such  appointment,  within 30 calendar
days  after  the  retiring  Auction  Administration  Agent's  giving  notice  of
resignation


                                     -40-





or the AAA Removing Banks' removal of the retiring Auction Administration Agent,
then the  retiring  Auction  Administration  Agent may,  on behalf of the Banks,
appoint a  successor  Auction  Administration  Agent,  with the  consent  of the
Borrower,  not to be  unreasonably  withheld,  which shall be a commercial  bank
organized under the Laws of the United States of America or of any state thereof
and having a combined  capital  and surplus of at least  $100,000,000.  Upon the
acceptance of any appointment as the Auction  Administration Agent hereunder and
under the Notes by a successor  Auction  Administration  Agent,  such  successor
Auction  Administration  Agent shall thereupon succeed to and become vested with
all  the  rights,  powers,  privileges,  and  duties  of  the  retiring  Auction
Administration  Agent,  and the retiring Auction  Administration  Agent shall be
discharged from its duties and  obligations  under this Agreement and the Notes.
After any retiring Auction  Administration Agent's resignation or removal as the
Auction  Administration  Agent hereunder and under the Notes,  the provisions of
this Section 8 shall inure to its benefit as to any actions  taken or omitted to
be  taken  by it  while  it was the  Auction  Administration  Agent  under  this
Agreement and the Notes.

                  (d) If either  Agent  fails to take any action  under any Loan
Paper  after an Event of  Default  and  within a  reasonable  time  after  being
reasonably  requested  to do so by any Bank (when such Bank is  entitled to make
such request under the Loan Papers and after such  requesting  Bank has obtained
the  concurrence of such other Banks as may be required  hereunder),  such Agent
shall not suffer or incur any  liability as a result of such failure or refusal,
but such  requesting  Bank may  request  such  Agent to  resign  as such  Agent,
whereupon such Agent shall so resign upon receiving such request.

                  (e) The Agent, in its capacity as a Bank,  shall have the same
Rights  under the Loan  Papers as any other  Bank and may  exercise  the same as
though it were not acting as the Agent or the Auction  Administration Agent; the
term "Bank" shall,  unless the context otherwise  indicates,  include the Agent;
and any resignation by the Agent hereunder shall not impair or otherwise  affect
any Rights which it has or may have in its capacity as an individual Bank.

                  (f) Subject in all respects to the terms and conditions of the
Loan Papers,  the Agents may be engaged in, or may  hereafter  engage in, one or
more  loan,  letter  of  credit,   leasing,  or  other  financing   transactions
(collectively,  the "other financings") not the subject of the Loan Papers, with
one or more of the Companies,  or may act as trustee on behalf of, or depositary
for, or otherwise engage in other business  transactions with one or more of the
Companies, in each case with no responsibility to account therefor to the Banks.
Without limiting Rights to which the Banks are  specifically  entitled under the
Loan Papers, no other Banks shall have, by virtue of their being parties hereto,
any  interest  in (i) any such  other  financings,  (ii) any  present  or future
guaranties  by or for the account of any Company which are not  contemplated  or
included in the Loan  Papers,  (iii) any present or future  offset  exercised by
such Agent in respect of such other  financings,  or (iv) any  present or future
property taken as security for any such other  financings  even if such property
may become  security for the  obligations of any Company  arising under the Loan
Papers by reason of a general  description of  indebtedness  related to any such
other  financings;  provided that, if any payments in respect of such guaranties
or such property or the proceeds thereof shall be


                                 -41-





applied to reduce the Obligations,  then each Bank shall be entitled to share in
such application according to its pro rata part thereof.

         8.2 Expenses.  Each Bank shall pay its pro rata part of any  reasonable
expenses  (including,  without limitation,  court costs,  reasonable  attorneys'
fees, and other costs of collection) incurred by either Agent in connection with
any of the Loan  Papers if such Agent does not  receive  reimbursement  therefor
from other sources within 60 days after incurred;  provided that each Bank shall
be entitled to receive its pro rata part of any reimbursement for such expenses,
or part thereof, which such Agent subsequently receives from such other sources.

         8.3  Proportionate  Absorption  of Losses.  Except as herein  provided,
nothing in the Loan Papers shall be deemed to give any Bank any  advantage  over
any other Bank insofar as the portion of the  Obligation  arising under the Loan
Papers is concerned,  or to relieve any Bank from absorbing its pro rata part of
any  losses  sustained  with  respect  to the  Obligation  (except to the extent
unilateral  actions or  inactions  by any Bank result in any credit,  allowance,
setoff,  defense, or counterclaim solely with respect to all or any part of such
Bank's pro rata part of the Obligation).

         8.4 Delegation of Duties;  Reliance. Each Agent may exercise any of its
duties under the Loan Papers by or through its officers,  directors,  employees,
attorneys, or agents (collectively,  "Representatives"),  and each Agent and its
Representatives  shall (a) be entitled to rely upon (and shall be  protected  in
relying upon) any writing, resolution, notice, consent, certificate,  affidavit,
letter,  cablegram,  telecopy,  telegram, telex or teletype message,  statement,
order, or other  documents or conversation  believed by it or them to be genuine
and  correct  and to have been  signed or made by the proper  Person  and,  with
respect to legal matters, upon opinion of counsel selected by such Agent, (b) be
entitled  to deem and treat  each  Bank as the owner and  holder of its pro rata
part of the Obligation for all purposes until,  subject to Section 9.20, written
notice of the  assignment  or  transfer  thereof  shall  have been  given to and
received by such Agent (and, any request, authorization, consent, or approval of
any Bank shall be conclusive and binding on each subsequent holder, assignee, or
transferee  of such  Lender's  pro rata part of the  Obligation  or  Participant
therein),  and (c) not be deemed to have notice of the occurrence of an Event of
Default  unless an officer of such  Agent has actual  knowledge  thereof or such
Agent has been notified thereof by a Bank or the Borrower.

         8.5      Limitation of Agents' Liability.

                  (a)  Neither  of  the  Agents  nor  any  of  their  respective
Representatives (as defined in Section 8.4) shall be liable for any action taken
or  omitted  to be taken by it or them  under the Loan  Papers in good faith and
believed by it or them to be within the discretion or power conferred upon it or
them by the Loan Papers or be responsible  for the  consequences of any error of
judgment,  except for fraud,  gross negligence,  or willful misconduct (IT BEING
THE  EXPRESS  INTENTION  OF THE  PARTIES  THAT THE AGENTS  AND THEIR  RESPECTIVE
REPRESENTATIVES SHALL HAVE NO LIABILITY FOR ACTIONS AND OMISSIONS RESULTING FROM
THEIR


                                      -42-





ORDINARY CONTRIBUTORY NEGLIGENCE OR UNDER CLAIMS OF STRICT
LIABILITY),   and   neither  of  the   Agents   nor  any  of  their   respective
Representatives has a fiduciary relationship with any Bank by virtue of the Loan
Papers  (provided  that nothing herein shall negate the obligation of each Agent
to account for funds received by it for the account of any Bank).

                  (b) Unless indemnified to its satisfaction against loss, cost,
liability, and expense, neither Agent shall be compelled to do any act under the
Loan Papers or to take any action  toward the  execution or  enforcement  of the
powers thereby created or to prosecute or defend any suit in respect of the Loan
Papers.  If  either  Agent  requests  instructions  from  the  Banks or from the
Majority  Banks,  as  the  case  may  be,  with  respect  to any  act or  action
(including,  but not limited to, any failure to act) in connection with any Loan
Paper,  such Agent  shall be  entitled  (but shall not be  required)  to refrain
(without  incurring any liability to any Person by so refraining)  from such act
or action  unless  and until it has  received  such  instructions.  In no event,
however,  shall either Agent or any of its  Representatives  be required to take
any action  which it or they  reasonably  determine  could  incur for it or them
criminal or onerous civil liability.

                  (c) Neither  Agent shall be  responsible  in any manner to any
Bank or any  Participant  for, and each Bank represents and warrants that it has
not relied upon  either  Agent in respect  of, (i) the  creditworthiness  of the
Borrower  and  the  risks  involved  to  such  Bank,  (ii)  the   effectiveness,
enforceability,  genuineness,  validity, or the due execution of any Loan Paper,
(iii) any representation,  warranty, document, certificate, report, or statement
made  therein  or  furnished  thereunder  or in  connection  therewith,  or (iv)
observation of or compliance with any of the terms,  covenants, or conditions of
any Loan  Paper on the part of any  Company.  Each  Bank also  acknowledges  and
agrees that it will, independently and without reliance upon either Agent or any
other  Bank and  based  on such  documents  and  information  as it  shall  deem
appropriate at the time,  continue to make its own credit decisions in taking or
not taking action under this Agreement. Each Bank agrees to indemnity each Agent
and its respective  Representatives and hold them harmless from and against (but
limited to such Bank's pro rata part of) any and all  liabilities,  obligations,
losses,  damages,  penalties,   actions,  judgments,  suits,  costs,  reasonable
expenses,  and reasonable  disbursements of any kind or nature  whatsoever which
may be imposed on, asserted against,  or incurred by them in any way relating to
or arising out of the Loan  Papers or any action  taken or omitted by them under
the Loan Papers,  except to the extent the same result solely from fraud,  gross
negligence, or willful misconduct by such Agent or its Representatives (IT BEING
THE  EXPRESS  INTENTION  OF THE  PARTIES  THAT THE AGENTS  AND THEIR  RESPECTIVE
REPRESENTATIVES SHALL HAVE NO LIABILITY FOR ACTIONS AND OMISSIONS RESULTING FROM
THEIR ORDINARY CONTRIBUTORY NEGLIGENCE OR UNDER CLAIMS OF STRICT LIABILITY).

         8.6  Default.  Upon  the  occurrence  and  continuance  of an  Event of
Default,  the Banks agree to promptly  confer in order that the  Majority  Banks
(or, if required by Section  9.15,  all Banks) may agree upon a course of action
for the enforcement of the Rights of the Banks; provided that the Agent shall be
entitled  (but not  obligated)  to proceed to take any actions  necessary in its
reasonable judgment to preserve the Rights of the Agents and the



                                     -43-





Banks  hereunder,  pending  agreement by the Majority  Banks (or, if required by
Section 9.15, all Banks) on the course of action to be taken.

         8.7 Limitation of Liability of Banks. No Bank or any Participant  shall
incur  any  liability  to any  other  Bank or  Participant  except  for  acts or
omissions in bad faith, and no Bank or any Participant shall incur any liability
to any Company or any other  Person for any act or omission of any other Bank or
any Participant.

         8.8      Relationship of Banks.  Nothing herein shall be construed as 
creating a partnership or joint venture among the Agents, the Agents and the 
Banks, or the Banks.

         8.9 Foreign  Banks.  Each Bank that is organized  under the laws of any
jurisdiction  other than the United  States of America or any State  thereof (a)
represents  to the Agents and the Borrower  that (i) under  applicable  Laws and
treaties no Taxes will be required to be withheld by the Agents or the  Borrower
with  respect  to any  payments  to be  made  to such  Bank  in  respect  of the
Obligation  and (ii) it has  furnished  to the Agent and the  Borrower  two duly
completed  copies of either  U.S.  Internal  Revenue  Service  Form 4224 or U.S.
Internal  Revenue  Service Form 1001  (wherein such Bank claims  entitlement  to
complete  exemption from U.S. federal  withholding tax on all interest  payments
hereunder),  and (b)  covenants  to (i) provide the Agent and the Borrower a new
Form 4224 or Form 1001 upon the obsolescence of any previously delivered form in
accordance  with  applicable  U.S.  laws and  regulations  and  amendments  duly
executed  and  completed by such Bank and (ii) comply from time to time with all
applicable  U.S.  laws and  regulations  with  regard  to such  withholding  tax
exemption.

         8.10 Benefits of Agreement. Except for requiring the Borrower's consent
under  Section  8.1(b) and the  representations  and covenants in Section 8.9 in
favor of the Borrower,  none of the  provisions of this Section 8 shall inure to
the benefit of any Company or any Person other than the Agents,  the Banks,  and
the Participants;  consequently,  neither any Company nor any other Person shall
be entitled to rely upon,  or to raise as a defense,  in any manner  whatsoever,
the failure of either Agent or any Bank to comply with such provisions.

SECTION 9.                 MISCELLANEOUS.

         9.1 Changes in GAAP. All accounting and financial  terms used in any of
the Loan Papers and the  compliance  with each  covenant  contained  in the Loan
Papers which relates to financial matters shall be determined in accordance with
GAAP,  except to the extent that a deviation  therefrom is  expressly  stated in
such  Loan  Papers.  Should a change in GAAP  require a change in any  method of
accounting or should any voluntary change in the accounting methods be permitted
pursuant  to  Section  5.19,  then such  change  shall not result in an Event of
Default if, at the time of such  change,  such Event of Default had not occurred
and was not then continuing, based upon the former methods of accounting used by
or on behalf of the Borrower; provided that, after any such change in accounting
methods,  the Financial  Statements required to be delivered shall either be (a)
supplemented  with  financial  information  prepared  in  comparative  form,  in
compliance with the former method of


                                 -44-





accounting used prior to such change,  as well as with the new method or methods
of accounting  and, for the purpose of  determining  whether an Event of Default
has  occurred,  Lenders  shall look solely to that portion of such  supplemental
information  that  complies  with  the  former  methods  of  accounting,  or (b)
supplemented  with financial  information  prepared in compliance  with such new
method or methods of accounting but accompanied by such information, in form and
detail satisfactory to Lenders, that will allow Lenders to readily determine the
effect of such changes in accounting methods on such Financial Statements,  and,
for the purpose of determining whether an Event of Default has occurred, Lenders
shall  look  solely to such  supplemental  information  as  adjusted  to reflect
compliance with such former method or methods of accounting.

         9.2 Money and Interest.  Unless stipulated otherwise (a) all references
in any of the Loan Papers to "dollars,"  "money,"  "payments,"  or other similar
financial or monetary  terms are  references to currency of the United States of
America  and (b) all  references  to  interest  are to simple  and not  compound
interest.

         9.3 Number and Gender of Words. Whenever in any Loan Paper the singular
number is used,  the same shall include the plural where  appropriate,  and vice
versa; and words of any gender in any Loan Paper shall include each other gender
where  appropriate.  The words "herein,"  "hereof," and  "hereunder,"  and other
words of similar  import refer to the relevant  Loan Paper as a whole and not to
any particular part or subdivision thereof.

         9.4 Headings.  The headings,  captions, and arrangements used in any of
the Loan Papers are, unless specified otherwise,  for convenience only and shall
not be deemed to limit,  amplify,  or modify the terms of the Loan  Papers,  nor
affect the meaning thereof.

         9.5 Exhibits.  If any Exhibit,  which is to be executed and  delivered,
contains  blanks,  the same shall be completed  correctly and in accordance with
the terms and provisions  contained and as contemplated  herein prior to, at the
time of, or after the execution and delivery thereof.

         9.6 Communications.  Unless specifically  otherwise provided,  whenever
any Loan Paper requires or permits any consent,  approval,  notice,  request, or
demand from one party to another,  such  communication must be in writing (which
may be by telex or telecopy)  to be  effective  and shall be deemed to have been
given on the day  actually  delivered  or, if mailed,  on the Business Day it is
received  by the party to be notified  at the  address  indicated  on Schedule 1
(unless  changed by notice  pursuant  hereto),  properly  stamped,  sealed,  and
deposited in the appropriate official postal service.

         9.7 Form and Number of Documents. Each agreement, document, instrument,
or other writing to be furnished  under any provision of this  Agreement must be
in form and  substance and in such number of  counterparts  as may be reasonably
required by the Agent and its counsel.

         9.8      Exceptions to Covenants.  The Borrower shall not take any 
action or fail to take any action which is permitted as an exception to any of
the covenants contained in any


                                    -45-





of the Loan Papers if such action or omission  would result in the breach of any
other covenant contained in any of the Loan Papers.

         9.9 Survival. All covenants, agreements, undertakings, representations,
and  warranties  made in any of the Loan Papers (a) shall  survive all  closings
under the Loan Papers, (b) except as otherwise indicated,  shall not be affected
by any investigation made by any party, and (c) unless otherwise provided herein
shall  terminate  upon the later of the  termination  of this  Agreement and the
payment in full of the Obligation.

         9.10  Governing  Law. The Loan Papers are being executed and delivered,
and are  intended to be  performed,  in the State of Texas,  and the laws (other
than conflict-of-laws provisions thereof) of such State and of the United States
of America  shall  govern the  Rights and duties of the  parties  hereto and the
validity, construction, enforcement, and interpretation of the Loan Papers.

         9.11 VENUE; SERVICE OF PROCESS;  JURY TRIAL. EACH PARTY HERETO, IN EACH
CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS,  HEREBY (a) IRREVOCABLY  SUBMITS TO
THE  NONEXCLUSIVE  JURISDICTION  OF THE STATE AND FEDERAL COURTS OF THE STATE OF
TEXAS AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY
LEGAL  PROCEEDING  ARISING OUT OF OR IN CONNECTION  WITH THE LOAN PAPERS AND THE
OBLIGATION  BY  SERVICE OF PROCESS AS  PROVIDED  BY TEXAS LAW,  (b)  IRREVOCABLY
WAIVES,  TO THE FULLEST EXTENT  PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
OR  HEREAFTER  HAVE  TO  THE  LAYING  OF  ANY  LITIGATION  ARISING  OUT OF OR IN
CONNECTION WITH THE LOAN PAPERS AND THE OBLIGATION BROUGHT IN DISTRICT COURTS OF
DALLAS COUNTY,  TEXAS,  OR IN THE UNITED STATES  DISTRICT COURT FOR THE NORTHERN
DISTRICT OF TEXAS,  DALLAS DIVISION,  (c) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY
LITIGATION BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT  FORUM,
(d) AGREES TO DESIGNATE  AND MAINTAIN AN AGENT FOR SERVICE OF PROCESS IN DALLAS,
TEXAS,  IN  CONNECTION  WITH ANY SUCH  LITIGATION  AND TO  DELIVER  TO THE AGENT
EVIDENCE  THEREOF,  IF  REQUESTED,  (e)  IRREVOCABLY  CONSENTS TO THE SERVICE OF
PROCESS OUT OF ANY OF THE  AFOREMENTIONED  COURTS IN ANY SUCH  LITIGATION BY THE
MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT  REQUESTED,  POSTAGE
PREPAID,  AT ITS ADDRESS SET FORTH HEREIN, (f) IRREVOCABLY AGREES THAT ANY LEGAL
PROCEEDING  AGAINST ANY PARTY HERETO  ARISING OUT OF OR IN  CONNECTION  WITH THE
LOAN  PAPERS  ON THE  OBLIGATION  MAY BE  BROUGHT  IN ONE OF THE  AFOREMENTIONED
COURTS, AND (g) IRREVOCABLY  WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ITS
RIGHT TO A JURY TRIAL IN ANY LITIGATION ARISING OUT OF OR IN CONNECTION WITH THE
LOAN PAPERS AND THE OBLIGATION.

         9.12     Maximum Interest Rate.  Regardless of any provision contained
in any of the Loan Papers, no Bank shall ever be entitled to contract for, 
charge, take, reserve, receive, or


                                   -46-





apply, as interest on the Obligation,  or any part thereof, any amount in excess
of the  Highest  Lawful  Rate,  and, in the event the Banks ever  contract  for,
charge,  take, reserve,  receive, or apply as interest any such excess, it shall
be  deemed a  partial  prepayment  without  penalty  of  principal  and  treated
hereunder as such and any remaining excess shall be refunded to the Borrower. In
determining  whether or not the  interest  paid or payable,  under any  specific
contingency,  exceeds the Highest Lawful Rate, the Borrower and the Banks shall,
to the maximum extent  permitted under  applicable Law, (a) treat all Borrowings
as but a single  extension of credit (and the Banks and the Borrower  agree that
such is the case and that provision herein for multiple  Borrowings and multiple
Notes is for convenience only), (b) characterize any nonprincipal  payment as an
expense,  fee,  or  premium  rather  than as  interest,  (c)  exclude  voluntary
prepayments  and the  effects  thereof,  and (d)  "spread"  the total  amount of
interest  throughout the entire  contemplated  term of the Obligation;  provided
that,  if the  Obligation  is paid and performed in full prior to the end of the
full  contemplated  term  thereof,  and if the interest  received for the actual
period of existence  thereof  exceeds the Highest  Lawful Rate,  the Banks shall
refund such  excess,  and, in such event,  the Banks shall not be subject to any
penalties provided by any Law for contracting for, charging,  taking, reserving,
or receiving  interest in excess of the Highest  Lawful Rate.  To the extent the
Laws of the  State of Texas are  applicable  for  purposes  of  determining  the
"Highest  Lawful Rate," such term shall mean the  "indicated  rate ceiling" from
time to time in effect under Article 1.04,  Title 79,  Revised Civil Statutes of
Texas,  as amended,  or, if permitted by applicable  Law and effective  upon the
giving of the notices required by such Article 1.04 (or effective upon any other
date  otherwise  specified  by  applicable  Law),  the  "monthly  ceiling,"  the
"quarterly  ceiling," or "annualized  ceiling" from time to time in effect under
such  Article  1.04,  whichever  the Banks  shall  elect to  substitute  for the
"indicated  rate ceiling," and vice versa,  each such  substitution  to have the
effect  provided in such Article  1.04;  and the Banks shall be entitled to make
such election from time to time and one or more times and, without notice to the
Borrower,  to leave any such substitute rate in effect for subsequent periods in
accordance  with  subsection  (h)(1) of such Article  1.04.  Pursuant to Article
15.10(b) of Chapter 15,  Subtitle 79, Revised Civil Statutes of Texas,  1925, as
amended,  the  Borrower  agrees that such  Chapter 15 (which  regulates  certain
revolving credit loan accounts and revolving triparty accounts) shall not govern
or in any manner apply to the Obligation.

         9.13 Invalid Provisions.  If any provision in any Loan Paper is held to
be illegal, invalid, or unenforceable,  such provision shall be fully severable;
the appropriate  Loan Paper shall be construed and enforced as if such provision
had never comprised a part thereof;  and the remaining  provisions thereof shall
remain in full force and effect and shall not be affected by such  provision  or
by its severance therefrom.  Furthermore,  in lieu of such provision there shall
be added  automatically  as a part of such Loan  Paper a  provision  as  similar
thereto as may be possible and be legal, valid, and enforceable.

         9.14     Entirety.  A LOAN AGREEMENT IN WHICH THE AMOUNT
INVOLVED EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE
AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR
BY THAT PARTY'S AUTHORIZED REPRESENTATIVE.  THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE DETERMINED SOLELY
FROM WRITTEN AGREEMENTS, DOCUMENTS, AND INSTRUMENTS, AND ANY



                                    -47-





PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO SUCH
WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM TIME TO TIME) AND THE OTHER
WRITTEN LOAN PAPERS EXECUTED BY THE BORROWER,  THE AGENTS,  AND THE BANKS (OR BY
THE  BORROWER  FOR THE  BENEFIT OF THE AGENTS OR ANY BANK)  REPRESENT  THE FINAL
AGREEMENT  BETWEEN THE PARTIES HERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS,  OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE
NO UNWRITTEN  ORAL  AGREEMENTS  BETWEEN THE PARTIES.  THIS PARAGRAPH IS INCLUDED
HEREIN  PURSUANT TO SECTION  26.02 OF THE TEXAS  BUSINESS AND COMMERCE  CODE, AS
AMENDED FROM TIME TO TIME.

         9.15  Amendments,  Etc. No amendment or waiver of any  provision of any
Loan Paper nor  consent to any  departure  therefrom  by the  Borrower  shall be
effective  unless the same shall be in writing and signed by the Majority  Banks
and the Borrower, and then, such amendment, waiver or consent shall be effective
only in the  specific  instance  and for the  specific  purpose for which given;
provided,  however,  that no  amendment,  waiver,  or consent  shall,  unless in
writing  and signed by all  Banks,  do any of the  following:  (a)  increase  or
decrease  the  Commitments,  or extend  the due date for  payment  of any of the
Obligation,  (b)  reduce  the  principal  amount of Loans due  hereunder  or any
interest rate or the amount of fees  applicable to the  Obligation  (except such
reductions as are contemplated by this Agreement), (c) amend or waive compliance
with this Section 9.15 or (d) amend the definition of Majority  Banks;  provided
that no amendment, waiver, or consent shall, unless in writing and signed by the
Agent in addition to the Banks  required  above to take such action,  affect the
rights or duties of the Agent under this or any other Loan Paper.

         9.16  Waivers.  No course of  dealing  nor any  failure or delay by the
Agents,  any Bank, or any of their respective  officers,  directors,  employees,
agents,  representatives,  or attorneys  with respect to exercising any Right of
the Banks  hereunder  shall  operate as a waiver  thereof.  A waiver  must be in
writing and signed by the Banks (or the Majority Banks, if permitted  hereunder)
to be effective, and such waiver will be effective only in the specific instance
and for the specific purpose for which it is given.

         9.17  Taxes. Any Taxes (excluding income taxes) payable or ruled 
payable by any  Tribunal in respect of this  Agreement  or any other Loan Paper 
shall be paid by the Borrower, together with interest and penalties, if any.

         9.18  Governmental Regulation.  Anything contained in this Agreement 
to the contrary notwithstanding, the Banks shall not be obligated to extend 
credit to the Borrower in violation of any Law.

         9.19  Multiple Counterparts.  This Agreement may be executed in a
number of identical counterparts, each of which shall be deemed an original for
all purposes and all of which constitute, collectively, one Agreement; but, in
making proof of this Agreement, it shall not be necessary to produce or account
for more than one such counterpart.  It is not


                                     -48-





necessary  that each Bank  execute  the same  counterpart  so long as  identical
counterparts  are executed by the Borrower and each Bank.  This Agreement  shall
become effective when counterparts hereof shall have been executed and delivered
to the Agent by each Bank, the Agents, and the Borrower, or, in the case only of
the Banks,  when the Agent shall have  received  telecopied,  telexed,  or other
evidence satisfactory to it that each Bank has executed and is delivering to the
Agent a counterpart hereof.

         9.20     Successors and Assigns; Participations; Assignments.

                  (a) This  Agreement  shall be binding  upon,  and inure to the
         benefit  of, the parties  hereto and their  respective  successors  and
         assigns,  except that (i) the Borrower may not, directly or indirectly,
         assign or  transfer,  or  attempt  to assign  or  transfer,  any of its
         Rights,  duties,  or obligations under any Loan Papers to which it is a
         party without the express written consent of all Banks, and (ii) except
         as permitted  under  Section 2.20 and this  Section  9.20,  no Bank may
         transfer, pledge, assign, sell participations in, or otherwise encumber
         its portion of the Obligation.

                  (b) Subject to the  provisions of this Section 9.20,  any Bank
         (other than a Designated  Lender) may sell to one or more Persons (each
         a  "Participant")  participating  interests (in each case not less than
         $2,500,000  and in an integral  multiple of $500,000) in its portion of
         the Obligation;  provided that each Bank's  Commitment must be at least
         50 percent of its Commitment on the date of this Agreement at all times
         and the Agent and the  Borrower  shall  have the right to  approve  any
         Participant which is not a financial  institution.  In the event of any
         such sale to a  Participant,  (i) such Bank shall remain a "Bank" under
         this  Agreement  and the  Participant  shall  not  constitute  a "Bank"
         hereunder,  (ii) such Bank's  obligations  under this  Agreement  shall
         remain unchanged,  (iii) such Bank shall remain solely  responsible for
         the performance thereof,  (iv) such Bank shall remain the holder of its
         share of the Obligation for all purposes under this Agreement,  and (v)
         the Borrower  and the Agent shall  continue to deal solely and directly
         with such Bank in connection  with such Bank's  Rights and  obligations
         under the Loan Papers. Participants shall have no Rights under the Loan
         Papers,  other than certain voting rights as provided below.  Each Bank
         shall be  entitled  to  obtain  (on  behalf  of its  Participants)  the
         benefits of Section 2 with respect to all  participations  in its Loans
         outstanding  from time to time.  No Bank shall  sell any  participating
         interest under which the  Participant  shall have any Rights to approve
         any amendment, modification, or waiver of any Loan Paper, except to the
         extent such amendment, modification, or waiver extends the due date for
         payment of any amount in respect of  principal,  interest,  or fees due
         under the Loan Papers,  or reduces the  interest  rate or the amount of
         principal or fees applicable to the Obligation  (except such reductions
         as are  contemplated by this  Agreement);  provided that in those cases
         where a Participant  is entitled to the benefits of Section 2 or a Bank
         grants Rights to its  Participants to approve  amendments to or waivers
         of the Loan Papers respecting the matters previously  described in this
         sentence,  such Bank must  include a voting  mechanism  in the relevant
         participation  agreement  whereby a majority of such Bank's  portion of
         the Obligation (whether held


                                          -49-





         by such Bank or  participated)  shall  control the vote for all of such
         Bank's portion of the  Obligation.  Except in the case of the sale of a
         participating interest to a Bank, the relevant participation  agreement
         shall not permit the  Participant  to transfer,  pledge,  assign,  sell
         participations in, or otherwise encumber its portion of the Obligation.

                  (c) Subject to the  provisions of this Section 9.20,  any Bank
         may,  with the prior  written  consent  of the  Agent and the  Borrower
         (which  will  not be  unreasonably  withheld),  sell  to  one  or  more
         financial  institutions  (each a "Purchaser") a proportionate  part (in
         each case not less  than  $2,500,000  and in an  integral  multiple  of
         $500,000) of its Rights and obligations  under the Loan Papers pursuant
         to an  assignment  agreement  between  such  Purchaser  and such  Bank;
         provided that each Bank's Commitment must be at least 50 percent of its
         Commitment  on the date of this  Agreement  at all times and  provided,
         further,  that NBD Bank may assign  all of its  Rights and  obligations
         under the Loan Papers to one or more of its  Affiliates  in  connection
         with a  corporation  reorganization  of NBD  Bank  and  its  affiliates
         without  the  consent of Agent or  Borrower.  Upon (i)  delivery  of an
         executed copy of the  assignment to the Borrower and the Agent and (ii)
         payment of a fee of $2500  from such Bank to the Agent,  from and after
         the assignment's  effective date (which shall be after the date of such
         delivery),  such  Purchaser  shall for all purposes be a Bank hereunder
         and shall have all the Rights and  obligations  of a Bank  hereunder to
         the same extent as if it were an original party hereto with commitments
         as set forth in the assignment agreement, and the transferor Bank shall
         be released from its obligations  hereunder to a corresponding  extent.
         Upon any transfer  pursuant to this Section  9.20(c),  Schedule 1 shall
         automatically be deemed to reflect the name, address, and Committed Sum
         of such  Purchaser  and the Agent shall deliver to the Borrower and the
         Banks an amended Schedule 1 reflecting such changes.  A Purchaser shall
         be subject to all the provisions in this Section 9.20 the same as if it
         were a Bank as of the date hereof.  Notwithstanding  anything herein to
         the contrary,  no Designated Lender may make an assignment  pursuant to
         the  provisions of this Section  9.20(c),  other than to the Bank which
         originally designated the Designated Lender.

                  (d) Each Bank (other than a Designated Lender) may designate a
         Designated  Lender to make Competitive Loans as a Bank pursuant to this
         Agreement;  provided,  however, that (i) no such Bank shall be entitled
         to make more than one such designation, (ii) each such Bank making such
         designation  shall retain the right to make  Competitive Bid Loans as a
         Bank pursuant to this Agreement and (iii) each such  designation  shall
         be to a Designated  Lender approved by the Borrower,  the Agent and the
         Auction  Administration Agent, and the parties to each such designation
         shall execute and deliver a Designation  Agreement,  for  acceptance by
         the Borrower, the Agent and the Auction Administration Agent. Upon such
         execution,  delivery, and acceptance, and the execution and delivery by
         the Borrower to the Designated Lender of a Competitive Note in the same
         principal  amount as that previously  delivered to the Bank making such
         designation,  from and  after  the  effective  date  specified  in each
         Designated  Agreement,  the designee thereunder shall be a party hereto
         with the right to make Competitive Bid Loans as a Bank pursuant to this
         Agreement, and shall have


                                           -50-





         the  obligations   related  thereto.  By  executing  and  delivering  a
         Designation  Agreement,  the Bank making the designation thereunder and
         its designee thereunder confirm and agree with each other and the other
         parties hereto as follows:

                           (i) such Bank makes no representation or warranty and
                  assumes no  responsibility  with  respect  to any  statements,
                  warranties or  representations  made in or in connection  with
                  this  Agreement  or any  other  Loan  Paper or the  execution,
                  legality, validity, enforceability,  genuineness,  sufficiency
                  or value of this  Agreement  or any  other  Loan  Paper or any
                  other  instrument  or document  furnished  pursuant  hereto or
                  thereto;

                           (ii) such Bank makes no  representation  or  warranty
                  and assumes no  responsibility  with respect to the  financial
                  condition of the Borrower or the  performance or observance by
                  the Borrower of any of its obligations under this Agreement or
                  any other  Loan  paper or any  other  instrument  or  document
                  furnished pursuant hereto or thereto;

                           (iii) such  designee  confirms that it has received a
                  copy of this  Agreement  and each other Loan  Paper,  together
                  with copies of the Current Financials and such other documents
                  and  information as it has deemed  appropriate to make its own
                  credit  analysis and  decision to enter into such  Designation
                  Agreement;

                           (iv) such designee  will,  independently  and without
                  reliance  upon the Agent,  the Auction  Administration  Agent,
                  such  designating  Bank or any  other  Bank and  based on such
                  documents and information as it shall deem  appropriate at the
                  time,  continue to make its own credit  decisions in taking or
                  not  taking  action  under  this  Agreement  or any other Loan
                  Paper;

                           (v)  such designee confirms that it is a Designated
                  Lender;

                           (vi) such designee  appoints and  authorizes  (A) the
                  Agent  to take  such  action  as agent  on its  behalf  and to
                  exercise such powers and  discretion  under this Agreement and
                  each  other Loan  Paper as are  delegated  to the Agent by the
                  terms  hereof  and  thereof,  together  with such  powers  and
                  discretion as are  reasonably  incidental  thereto and (B) the
                  Auction  Administration Agent to take such actions as agent on
                  its behalf and to exercise  such powers and  discretion  under
                  this  Agreement  and each other Loan Paper as are delegated to
                  the  Auction  Administration  Agent by the  terms  hereof  and
                  thereof,  together  with such  powers  and  discretion  as are
                  reasonably incidental thereto; and

                           (vii) such  designee  agrees that it will  perform in
                  accordance  with their terms all of the  obligations  which by
                  the terms of this  Agreement  and each  other  Loan  Paper are

         Taxes will be required to be withheld by the Agent,  the  Borrower,  or
         the  transferor  Bank with  respect to any  payments to be made to such
         Purchaser in respect of the Obligation,  (ii) to furnish to each of the
         transferor  Bank, the Agent, and the Borrower two duly completed copies
         of either U.S.  Internal  Revenue  Service  Form 4224 or U.S.  Internal
         Revenue Service Form 1001 (wherein such Purchaser claims entitlement to
         complete  exemption from U.S.  federal  withholding tax on all interest
         payments  hereunder),  and  (iii) to  agree  (for  the  benefit  of the
         transferor Bank, the Agent, and the Borrower) to provide the transferor
         Bank, the Agent, and the Borrower a new Form 4224 or Form 1001 upon the
         obsolescence  of any  previously  delivered  form  in  accordance  with
         applicable  U.S. laws and  regulations and amendments duly executed and
         completed by such  Purchaser,  and to comply from time to time with all
         applicable  U.S. laws and regulations  with regard to such  withholding
         tax exemption.

         9.21  Confidentiality.  All  nonpublic  information  furnished  by  the
Companies to the Agents or the Banks in connection  with the Loan Papers and the
transactions  contemplated thereby will be treated as confidential,  but nothing
herein  contained shall limit or impair the Agent's or any Bank's right, and the
Agent and the Banks shall be entitled,  (a) to disclose the same to any Tribunal
or as otherwise  required by Law or to any prospective or actual  Participant or
Purchaser  or to the  respective  affiliates,  directors,  officers,  employees,
attorneys,  and agents of any  prospective  or actual  Participant  or Purchaser
(provided that such prospective or actual Participant or Purchaser has agreed in
writing to comply with this Section  9.21),  (b) to use such  information to the
extent pertinent to an evaluation of the Obligation,  (c) to enforce  compliance
with the terms and  conditions  of the Loan  Papers,  and (d) to take any action
which the Agent or any Bank deems necessary to protect its interests if an Event
of Default has occurred and is continuing.

         9.22 Conflicts and Ambiguities.  Any conflict or ambiguity  between the
terms and  provisions  herein and terms and  provisions  in any other Loan Paper
shall be controlled by the terms and provisions herein.

         9.23 General  Indemnification.  The Borrower shall indemnity,  protect,
and hold the Agents and the Banks and their  respective  parents,  subsidiaries,
directors, officers, employees,  representatives,  agents, successors,  assigns,
and  attorneys  (collectively,  the  "Indemnified  Parties")  harmless  from and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
actions,   judgments,   suits,  claims,  costs,  expenses  (including,   without
limitation,  attorneys'  fees and legal expenses  whether or not suit is brought
and settlement  costs), and disbursements of any kind or nature whatsoever which
may be imposed on, incurred by, or asserted against the Indemnified  Parties, in
any way relating to or arising out of the Loan Papers or any of the transactions
contemplated therein (collectively, the


                                       -52-





"Indemnified   Liabilities"),   to  the  extent  that  any  of  the  Indemnified
Liabilities  results,  directly  or  indirectly,  from any claim made or action,
suit,  or  proceeding  commenced  by or on behalf of any  Person  other than the
Indemnified  Parties;  PROVIDED,  HOWEVER,  THAT ALTHOUGH EACH INDEMNIFIED PARTY
SHALL HAVE THE RIGHT TO BE  INDEMNIFIED  FROM ITS OWN  ORDINARY  NEGLIGENCE,  NO
INDEMNIFIED  PARTY SHALL HAVE THE RIGHT TO BE INDEMNIFIED  HEREUNDER FOR ITS OWN
FRAUD,  GROSS  NEGLIGENCE,   OR  WILLFUL  MISCONDUCT.   The  provisions  of  and
undertakings and  indemnification  set forth in this paragraph shall survive the
satisfaction and payment of the Obligation and termination of this Agreement for
the period of time set forth in any applicable statute of limitations.

         9.24  Investment  Representation.  The Notes are being  acquired by the
Banks for their own respective  account for investment and not with the view to,
or for sale in connection with, any distribution  thereof.  The Banks understand
that the Notes will not be registered  under the  Securities  Act of 1933 or any
securities  act of any state  pursuant  to an  exemption  from the  registration
provisions  thereof.  Each Bank shall indemnify the Borrower against and hold it
harmless from any claim,  and any cost or expense  therefrom,  that the Borrower
shall have  committed a violation of applicable Law by virtue of the exercise by
such Bank of its right to sell participations or make assignments hereunder.

                               MATERIAL LITIGATION



1.  CASE:             MBF Corporation vs. Century Business Communications

    NATURE OF CASE:   Tortious interference with a business relationship (suit
                      filed 7/30/90)

    CLAIM AMOUNT:     Original claim amount $500,000 + $2,500,000 in
                      punitive damages

    COMMENTS:         Trial was held and a summary judgment granted in
                      Century's favor.  Appealed to MS Supreme Court.
                      Adverse decision is not expected.

2.  CASE:             Robert C. James, Individually and d/b/a Southwest
                      Cellular vs. McAllen Cellular Telephone Company

    NATURE OF CASE:   Case was originally against Cellutel and is a dispute over
                      owed commissions.  Nature of case has changed to

                      evaluate our estimate of actual damages which will
                      probably be between $18,000 and $30,000 for lost
                      commissions.

                  FORM OF OPINION OF BORROWER'S COUNSEL


                       ____________________, 19___


Bank One, Texas, N.A.,
         as Agent for the Banks as defined in
         the Credit Agreement referred to below
Bank One Center
1717 Main Street, Third Floor
Dallas  Texas  75201

Ladies and Gentlemen:

         We have acted as counsel for Century  Telephone  Enterprises,  Inc.,  a
Louisiana  corporation  (the  "Borrower"),  in connection with the execution and
delivery of the Competitive  Advance and Revolving Credit Facility  Agreement of
even date herewith (the "Credit  Agreement") among the Borrower,  the Agent, the
Auction Administration Agent, and the Banks party thereto.

         This  opinion is delivered to you pursuant to Section 4.1 of the Credit
Agreement  and upon the express  instruction  of the  Borrower.  Unless  defined
herein,  capitalized  terms have the meanings  given to such terms in the Credit
Agreement.

         In connection  with this opinion,  we have examined  executed copies of
the Credit  Agreement  and  Competitive  Notes and Committed  Notes  executed by
Borrower and payable to each Bank  (collectively,  the "Loan  Papers").  We have
also examined and relied upon the  representations  and warranties as to factual
matters  contained  in or made  pursuant to the Loan  Papers and such  corporate
documents  and  records  of the  Borrower,  certificates  of  public  officials,
officers of the Borrower,  and such other documents as we have deemed  necessary
or appropriate for the purposes of this opinion. In stating our opinion, we have
assumed the  genuineness  of all  signatures  of, and the authority of,  persons
signing  the Loan  Papers  on  behalf  of the  parties  thereto  other  than the
Borrower,  the authenticity of all documents  submitted to us as originals,  the
conformity to authentic original  documents of all documents  submitted to us as
certified,  conformed, or photostatic copies, and that all documents, books, and
records made available to us by the Borrower are accurate and complete.

         We are  qualified  to practice  law in the State of  Louisiana  and our
opinion is restricted to the laws of the State and the federal law of the United
States of America.  We have  assumed  that  insofar as the  substantive  laws of
states other than  Louisiana  that may be  applicable  to any matters  opined on
herein, such laws are the same as the substantive laws of the State of Louisiana
applied by us herein.

         Based upon the foregoing, we are of the opinion that:

         1. The Borrower is a corporation duly organized,  validly existing, and
in good  standing  under the laws of its state of  incorporation.  Except  where
failure would not reasonably be expected to have a Material Adverse Effect,  the
Borrower (a) is duly qualified to transact business and is in good standing as a
foreign  corporation  in each  jurisdiction  where the  nature and extent of its
business  and  properties  require  the same  and (b)  possesses  all  requisite
authority,  power, licenses,  permits, and franchises to conduct its business as
is now being conducted.  The Borrower possesses all requisite authority,  power,
licenses, permits, and franchises to execute, deliver, and comply with the terms
of the Loan  Papers,  all which have been duly  authorized  and  approved by all
necessary  corporate  action and,  except where failure would not  reasonably be
expected to have a Material Adverse Effect,  for which no approval or consent of
any Person or Tribunal is required  which has not been obtained and no filing or
other  notification  to any Person or Tribunal  is  required  which has not been
properly completed.

         2. The Borrower is not, nor will the execution, delivery,  performance,
or  observance  of the Loan Papers  cause the Borrower to be, (a) to the best of
our knowledge,  in violation of any laws or any Material  Agreements to which it
is a party, other than such violations which would not reasonably be expected to
have a Material Adverse Effect, or (b) in violation of its bylaws or charter.

         3. We have no knowledge of any Material  Litigation or  outstanding  or
unpaid Material judgments against the Borrower,  except as described on Schedule
3.6 attached to the Credit Agreement.

         4. The Borrower is not (a) a "holding company," a "subsidiary  company"
of  a  "holding  company,"  an  "affiliate"  of  a  "holding  company"  or  of a
"subsidiary  company" of a "holding  company," or a "public  utility" within the
meaning of the Public  Utility  Holding  Company Act of 1935, as amended,  (b) a
"public utility" within the meaning of the Federal Power Act, as amended, (c) an
"investment  company" or  "controlled"  by an  "investment  company"  within the
meaning of the  Investment  Company Act of 1940, as amended,  (d) an "investment
advisor" within the meaning of the Investment  Advisors Act of 1940, as amended,
or (e) subject to the jurisdiction of the Federal  Communications  Commission or
any public service commission as a common carrier.

         5. Each of the Loan Papers  constitutes a valid, and binding obligation
of the Borrower,  enforceable against the Borrower in accordance with its terms,
except  as  enforceability   may  be  limited  by  (a)  applicable   bankruptcy,
insolvency,  fraudulent transfer,  reorganization,  moratorium, or other similar
laws affecting  creditors'  rights generally,  (b) general  principles of equity
(whether  enforcement is sought by proceedings in equity or at law), and (c) the
qualification that certain provisions of the Loan Papers may be

Page 3

unenforceable in whole or in part under the laws of the State, but the inclusion
of such  provisions does not affect the validity of any Loan Paper and each Loan
Paper  contains  adequate  provisions for enforcing  payment of the  Obligations
secured  thereby  or  provided  for  therein,  as the case  may be,  and for the
practical  realization of the rights and benefits afforded thereby,  though they
may result in delays  thereof  (and we  express  no  opinion as to the  economic
consequences, if any, of such delays).

         6. Under the circumstances of the actions as contemplated by the Credit
Agreement, courts of the State of Louisiana would honor the choice of law agreed
to by the parties in the Credit Agreement.

         This opinion is furnished  solely in connection  with the  transactions
referred to in the Credit  Agreement  and may not,  without our  permission,  be
circulated  to any  Person,  except you,  your legal  counsel,  the Banks,  bank
supervisory authorities,  prospective Participants or Purchasers, or as required
by law or order of a court or other  legal  process  and may not be relied  upon
except  by you,  your  legal  counsel,  the  Banks  or  actual  Participants  or
Purchasers.

                                                     Very truly yours,

                                                     BOLES, BOLES & RYAN
