request  delivered  to the Agent at least three (3)  Business  Days prior to the
date of such issuance,  renewal,  extension or reissuance.  Concurrently with or

Borrower or Borrower's Subsidiary,  if applicable,  shall execute and deliver to
the Agent an  application  and  agreement  with respect to the Letter of Credit,
said  application and agreement to be in the form customarily used by the Agent.

terms of this Agreement and the Agent's form of  application  and agreement with
respect to Letters of Credit. The Agent shall not be obligated to issue,  renew,
extend or reissue  such  Letters of Credit if (i) the Agent does not approve the
requested  form of the  Letter  of  Credit  or any of the  terms  thereof,  such
approval not to be unreasonably withheld,  (ii) the amount thereon when added to
the amount of the outstanding Letters of Credit exceeds $7,500,000.00,  or (iii)
the amount thereof when added to the total outstanding Advances under Facility A
would  exceed the  Facility A Borrowing  Base  Amount  then in effect.  Borrower
agrees to pay the Agent a fee for the  issuance of each Letter of Credit,  which
fee shall be due and payable by the Borrower to the Agent upon  issuance of each
Letter of Credit by the  Agent  and on each  anniversary  date of such  issuance
while such  Letter of Credit is  outstanding.  The said fee shall be a per annum
fee in the  amount  equal to the  lesser of either (a) 1.5% per annum or (b) the
applicable  Eurodollar Margin, times the face amount of the Letter of Credit for
such period (calculated separately for each Letter of Credit).

     SECTION  2.3.4.  MANNER AND NOTICE OF  BORROWING  UNDER THE LINE OF CREDIT.
Requests For Advances  under the Line of Credit may be made by the Borrower,  in
writing (including facsimile  transmission) to the Agent and such requests shall
be fully authorized by the Borrower if made by any one of the persons designated
by the  Borrower  in writing to the Agent.  The form of Request  for  Advance is
attached  hereto as Exhibit "B", and includes a  designation  by Borrower of the
Borrowing  Date.  The Agent  shall have the right,  but not the  obligation,  to
verify any telephone  requests by calling the person who made the request at the
telephone  number  designated by the Borrower in writing to the Agent.  Requests
For Advances  must be received by not later than 11:00 a.m.  (Central  Time) (i)
one (1) Business Day prior to the Borrowing Date in the case of Base Rate Loans,
or (ii) three (3) Business Days prior to any proposed Borrowing Date in the case
of Eurodollar Loans.  Upon receipt of such Request for Advance,  the Agent shall
advise each Lender thereof; provided, that if the Lenders have received at least
one (1) Business  Day's  notice of such Advance  prior to funding of a Base Rate
Loan,  or at least three (3) Business  Days' notice of each advance prior to the
funding in the case of a Eurodollar Loan, each Lender shall provide the Agent at
its office at 313 Carondelet  Street,  New Orleans,  Louisiana  70130, not



                                       20


later than 1:00 p.m.,  Central  Time,  on the  Borrowing  Date,  in  immediately
available funds, its Pro Rata share of the requested Advance,  but the aggregate
of all such outstanding fundings by each Lender shall never exceed such Lender's
available  Line of Credit  Loan  Commitment.  Not later than 2:00 p.m.,  Central
Time,  on the  Borrowing  Date,  the Agent shall make  available to Borrower the
aggregate  amount of such  requested  Advance by  crediting  same to  Borrower's
checking account and mailing the resulting credit advice to Borrower.  The Agent
and the  Lenders  shall not incur any  liability  to Borrower in acting upon any
Request for Advance referred to above which the Agent and the Lenders believe in
good  faith to have been  given by a duly  authorized  officer  or other  person
authorized to borrow on behalf of Borrower or for otherwise acting in good faith
under this Section 2.3.4.  Upon funding of Advances by the Lenders in accordance
with this  Agreement,  pursuant to any such Request for Advance,  Borrower shall
have effected Advances  hereunder.  Each Request for Advance for a Facility Loan
must specify  whether such Loan is a  Eurodollar  Loan or a Base Rate Loan,  and
whether  such Loan is under  Facility A or Facility  B. A Lender's  copy of such
credit advice  indicating  such deposit to the account of the Borrower  shall be
deemed  conclusive  evidence of the  Borrower's  indebtedness  to such Lender in
connection with such borrowing.  The aggregate  outstanding  amount of principal
and  interest  due by the  Borrower  at any given  time under the Line of Credit
shall be and  constitute the  indebtedness  of the Borrower to the Lenders under
the Notes made by the Borrower.  When each Advance is made by the Lenders to the
Borrower  hereunder,  the Borrower  shall be deemed to have renewed and reissued
the Notes for the amount of the Advance  plus all amounts due by the Borrower to
the Lenders under the Line of Credit Loan Commitment  immediately  prior to such
advance.

     SECTION 2.3.5. USE OF PROCEEDS.  The Borrower shall use the proceeds of the
Facility  Loans  to  finance  working  capital   requirements   and  for  direct
investments in its oil and gas operations.

     SECTION 2.3.6.  SEVERAL  OBLIGATIONS.  The obligations of the Lenders under
the Line of Credit Loan Commitment are several and not joint. The failure of any
Lender to make an Advance  required to be made by it shall not relieve any other
Lender of its obligation to make its Advance, and no Lender shall be responsible
for the failure of any other Lender to make the Advance to be made by such other
Lender.

     SECTION 2.4. HEDGE COMMITMENT.  Subject to the terms and conditions of this
Agreement,  the Agent agrees to extend the Hedge L/C Line to the  Borrower,  and
issue,  for the account of the  Borrower or a  Subsidiary  that is a  Guarantor,
stand-by  letters  of  credit  up to a  maximum  aggregate  principal  amount of
$5,000,000.00,  to beneficiaries that are acceptable to the Agent, in connection
with and as support for  Borrower's  or such  Subsidiary's  execution of Hedging
Agreements   and/or  other   commodity   price  hedging   agreements   involving
Hydrocarbons  that  are part of the  Mortgaged  Properties  (the  "Hedge-Related
Letters of  Credit").  Each such  Hedge-Related  Letter of Credit  shall have an
expiry  date no later than the earlier of one (1) year from the date of issuance
or the Facility A Termination  Date. The Hedge Commitment and the Hedge L/C Line
shall  terminate  on the  Facility  A  Termination  Date.  The  Borrower  hereby
unconditionally  agrees to pay and  reimburse  the Agent for the  amount of each
payment or funding by Agent under any Hedge-Related  Letter of Credit that is in
substantial  compliance with the  requirements



                                       21


of such Hedge-Related  Letter of Credit at or prior to the date on which payment
is made by the Agent to the beneficiary thereunder, without presentment, demand,
protest or other  formalities of any kind.  Upon receipt from any beneficiary of
any  Hedge-Related  Letter  of Credit  of any  demand  for  payment  under  such
Hedge-Related  Letter of Credit, the Agent shall promptly notify the Borrower of
the demand  and the date upon  which such  payment is to be made by the Agent to
such beneficiary in respect of such demand. In the event such payment or funding
by the  Agent is on a  Hedge-Related  Letter  of Credit  that was  issued  under
Facility A pursuant to Section  2.4.2  below,  the Lenders  shall be entitled to
reimbursement pursuant to an Advance under the Notes, and the Borrower agrees to
deliver to Agent a Request for Advance form to cover such Advance.  In the event
such payment or funding by the Agent is on a Hedge-Related Letter of Credit that
was not issued under Facility A, then the Borrower is unconditionally obligated,
as provided above, to reimburse  promptly the Agent.  The default  interest rate
applicable to such Reimbursement  Obligation shall be 18% per annum. The Line of
Credit Loan  Commitment  of each Lender  shall be deemed to be utilized  for all
purposes hereof in an amount equal to such Lender's Commitment Percentage of the
undrawn face amount of such Hedge-Related Letter of Credit issued under Facility
A. Each Lender agrees that, upon issuance under Facility A of any  Hedge-Related
Letter of Credit hereunder,  it shall  automatically  acquire a participation in
the Agent's  liability  under such  Hedge-Related  Letter of Credit in an amount
equal to such Lender's Commitment Percentage of such liability,  and each Lender
(other than Agent) thereby shall  absolutely,  unconditionally  and  irrevocably
assume,  as  primary  obligor  and not as surety,  and shall be  unconditionally
obligated to pay and discharge  when due, its  Commitment  Percentage of Agent's
liability under such Hedge-Related Letter of Credit, provided such Hedge-Related
Letter of Credit was issued in accordance with the provisions of this Agreement.

     SECTION 2.4.1. PROCEDURE FOR OBTAINING HEDGE-RELATED LETTERS OF CREDIT. The
amount and date of issuance, renewal, extension or reissuance of a Hedge-Related
Letter of Credit  pursuant to Section 2.4 shall be designated by the  Borrower's
written request delivered to the Agent at least three (3) Business Days prior to
the date of such issuance,  renewal, extension or reissuance.  Concurrently with
or promptly following the delivery of the request for a Hedge-Related  Letter of
Credit, the Borrower or Borrower's Subsidiary, if applicable,  shall execute and
deliver  to  the  Agent  an  application  and  agreement  with  respect  to  the
Hedge-Related Letter of Credit, said application and agreement to be in the form
customarily used by the Agent. The terms of this Agreement shall control in case
of any  conflict  between the terms of this  Agreement  and the Agent's  form of
application and agreement with respect to Hedge-Related  Letters of Credit.  The
Agent  shall  not  be  obligated  to  issue,   renew,  extend  or  reissue  such
Hedge-Related Letters of Credit if (i) the Agent does not approve the designated
beneficiary,  the requested form of the Hedge-Related Letter of Credit or any of
the terms  thereof,  such  approval not to be  unreasonably  withheld,  (ii) the
amount thereon when added to the amount of the outstanding Hedge-Related Letters
of Credit exceeds $5,000,000.00, or (iii) the Borrower is not in compliance with
the terms and  conditions  of this  Agreement  (including  Section  13.10).  The
Borrower  agrees to pay the Agent a fee for the  issuance of each  Hedge-Related
Letter of  Credit,  which fee shall be due and  payable by the  Borrower  to the
Agent upon issuance of each  Hedge-Related  Letter of Credit by the Agent and on
each anniversary date of such issuance while such Hedge-Related Letter of



                                       22


Credit is outstanding. The said fee shall be a per annum fee in the amount equal
to the  lesser of either (a) the  applicable  Eurodollar  Margin  times the face
amount of the  Hedge-Related  Letter of Credit  for such  period or (b) 1.5% per
annum (calculated separately for each Hedge-Related Letter of Credit).

     SECTION  2.4.2.  HEDGE L/C LINE AND  FACILITY A.  Hedge-Related  Letters of
Credit, at the Borrower's option, may be issued by Agent outside of the Facility
A Borrowing Base Amount. If Borrower  exercises the foregoing  option,  the face
amount of each  Hedge-Related  Letter of Credit so  issued,  will not affect the
availability  of funds under the Facility A Borrowing Base Amount.  However,  if
there are  funds  available  under  Facility  A and the  Borrower  elects  for a
Hedge-Related  Letter of Credit to be  issued  under  Facility  A, then the face
amount  of  any  such   Hedge-Related   Letter  of  Credit  shall  reduce  on  a
dollar-for-dollar basis the availability of funds under the Facility A Borrowing
Base Amount then in effect.

     SECTION   2.4.3.SECURITY  FOR  REIMBURSEMENT   OBLIGATIONS   PERTAINING  TO
HEDGE-RELATED  LETTERS OF CREDIT.  The parties  acknowledge  that  Reimbursement
Obligations  pertaining  to  Hedge-Related  Letters of Credit are secured by the
Collateral Documents.


                                   ARTICLE III

                       NOTES EVIDENCING THE FACILITY LOANS


     SECTION 3.1. NOTES.

     SECTION 3.1.1.  FORM OF NOTES. The Facility Loans under Facility A shall be
evidenced   by  the   Facility  A  Notes  in  the   aggregate   face  amount  of
$75,000,000.00.  The Facility  Loans under  Facility B shall be evidenced by the
Facility B Notes in the aggregate face amount of $25,000,000.00. Notwithstanding
the face amount of the Notes,  the actual  principal amount due from Borrower to
the Lenders on account of the Notes, as of any date of computation, shall be the
sum of Advances then and theretofore made on account thereof, less all principal
payments  actually  received by Lender in collected funds with respect  thereto.
Although the Notes are dated of even date herewith,  interest in respect thereof
shall be payable only for the period  during which the loans  evidenced  thereby
are outstanding and, although the stated amount of the Notes may be higher,  the
Notes shall be  enforceable,  with respect to  Borrower's  obligation to pay the
principal  amount thereof,  only to the extent of the unpaid principal amount of
the Facility Loans.

     SECTION 3.1.2. ISSUANCE OF ADDITIONAL NOTES From time to time new Notes may
be issued to other  Lenders as such Lenders  become  parties to this  Agreement.
Upon request  from the Agent,  Borrower  shall  execute and deliver to Agent any
such new or  additional  Notes.  From time to time as new Notes are  issued  the
Agent shall require that each Lender exchange their Notes for newly issued Notes
to better reflect the extent of each Lender's  Commitment  hereunder.  The Agent
shall,  upon the  written  request of  Borrower,  cause the Lenders to return to
Borrower the Notes which have been replaced  within a reasonable  period of time
after



                                       23


Borrower's  request.  Under no circumstances  will the issuance of new Notes, or
the return of the Notes to the Borrower which have been  replaced,  constitute a
novation or other discharge of the  outstanding  indebtedness of Borrower to the
Lenders under the Line of Credit.

     SECTION 3.1.3. PAYMENT OF THE NOTES. Subject to the requirements of Article
VIII  below,  interest  on the unpaid  principal  balance of the Notes  shall be
payable on each Interest  Payment Date and for Advances under Facility A, on the
Facility A Termination  Date, and for Advances under Facility B, on the Facility
B Termination  Date.  Subject to the requirements of Article VIII below, (i) the
outstanding principal due under the Notes resulting from Advances under Facility
A shall be due and  payable on the  Facility A  Termination  Date,  and (ii) the
outstanding principal due under the Notes resulting from Advances under Facility
B shall be due and payable on the Facility B Termination Date.

     SECTION  3.1.4.  PAYMENT TO THE  LENDERS.  Each  Lender's  Pro Rata Part of
payment or  prepayment  of the Loans shall be directed by wire  transfer to such
Lender by the Agent at the  address  provided  to the Agent for such  Lender for
payments no later than 2:00 p.m., Lafayette, Louisiana, time on the Business Day
such  payments or  prepayments  are deemed  hereunder  to have been  received by
Agent; provided, however, in the event that any Lender shall have failed to make
an Advance as contemplated under Article II hereof (a "Defaulting Bank") and the
Agent or  another  Lender or  Lenders  shall  have made  such  Advance,  payment
received  by Agent  for the  account  of such  Defaulting  Bank(s)  shall not be
distributed to such Defaulting Bank(s) until such Advance or Advances shall have
been  repaid  in full to the  Lender or  Lenders  who  funded  such  Advance  or
Advances.  Any  payment or  prepayment  received  by the Agent at any time after
12:00 noon, Lafayette, Louisiana, time on a Business Day shall be deemed to have
been received on the next Business  Day.  Interest  shall cease to accrue on any
principal as of the end of the day  preceding the Business Day on which any such
payment or prepayment is deemed hereunder to have been received by the Agent. If
the Agent  fails to  transfer  any  principal  amount to any Lender as  provided
above,  then the Agent  shall  promptly  direct  such  principal  amount by wire
transfer to such Lender.

     SECTION  3.1.5.  SHARING OF  PAYMENTS,  ETC. If any Lender shall obtain any
payment (whether voluntary,  involuntary, or otherwise) on account of the Loans,
(including,  without limitation, any set-off) which is in excess of its Pro Rata
Part of payments on the Loans, as the case may be, obtained by all Lenders, such
Lender shall  purchase  from the other  Lenders such  participation  as shall be
necessary to cause such  purchasing  Lender to share the excess payment pro rata
with each of them;  provided  that, if all or any portion of such excess payment
is thereafter  recovered  from such  purchasing  Lender,  the purchase  shall be
rescinded  and the  purchase  price  restored  to the  extent  of the  recovery.
Borrower  agrees that any Lender so  purchasing  a  participation  from  another
Lender  pursuant to this  Section may, to the fullest  extent  permitted by law,
exercise  all of its rights of  payment  (including  the right of  offset)  with
respect  to such  participation  as fully  as if such  Lender  were  the  direct
creditor of Borrower in the amount of such participation.

     SECTION  3.1.6.  NON-RECEIPT  OF FUNDS BY THE AGENT  Unless the Agent shall
have been notified by a Lender or Borrower  (the  "Payor")  prior to the date on
which such Lender is to make  payment to the Agent of the proceeds of a Facility
Loan to be made by it  hereunder  or  Borrower



                                       24


is to make a payment to the Agent for the account of one or more of the Lenders,
as the case may be (such payment  being herein  called the "Required  Payment"),
which notice shall be effective upon receipt,  that the Payor does not intend to
make the Required  Payment to the Agent,  the Agent may assume that the Required
Payment has been made and may, in reliance upon such  assumption  (but shall not
be required to), make the amount thereof available to the intended  recipient on
such date and,  if the Payor has not in fact made the  Required  Payment  to the
Agent,  the  recipient of such payment  shall,  on demand,  pay to the Agent the
amount made  available to it together  with  interest  thereon in respect of the
period  commencing on the date such amount was made available by the Agent until
the date the Agent  recovers such amount at the rate  applicable to such portion
of the  applicable  Facility  Loan.  Any  payment  due from any  Lender to Agent
pursuant hereto shall bear interest at the Federal Funds Rate.

                                   ARTICLE IV

                                 INTEREST RATES

     SECTION 4.1. OPTIONS.

     SECTION 4.1.1. BASE RATE LOANS. On Base Rate Loans,  Borrower agrees to pay
interest  calculated  on the basis of a year  consisting  of  365/366  days with
respect to the unpaid  principal amount of each Base Rate Loan from the date the
proceeds  thereof are made  available  to Borrower  until  maturity  (whether by
acceleration  or  otherwise),  at a  varying  rate  per  annum  equal to (A) for
Advances  under Facility A, the lesser of (i) the Maximum Rate and (ii) the Base
Rate plus the Base Rate  Margin;  and (B) for  Advances  under  Facility  B, the
lesser of (i) the  Maximum  Rate and (ii) the Base Rate plus the  margin  amount
(expressed as a percentage) as established  by Lenders.  Past due principal,  to
the extent  permitted by law, shall bear interest,  payable upon demand,  at the
lesser of (i) the Maximum Rate and (ii) the default rate specified in the Notes.

     SECTION 4.1.2.  EURODOLLAR LOANS. On Eurodollar  Loans,  Borrower agrees to
pay  interest  calculated  on the  basis of a year  consisting  of 360 days with
respect to the unpaid principal amount of each Eurodollar Loan from the date the
proceeds  thereof are made  available  to Borrower  until  maturity  (whether by
acceleration  or  otherwise),  at a  varying  rate  per  annum  equal to (A) for
Advances  under  Facility  A, the  lesser of (i) the  Maximum  Rate and (ii) the
Eurodollar Rate plus the Eurodollar  Margin; and (B) for Advances under Facility
B, the  lesser of (i) the  Maximum  Rate and (ii) the  Eurodollar  Rate plus the
margin amount  (expressed as a percentage) as  established by Lenders.  Past due
principal,  to the extent  permitted  by law,  shall bear  interest,  payable on
demand,  at the  lesser  of (i) the  Maximum  Rate  and (ii)  the  default  rate
specified in the Notes. Upon three (3) Business Days written notice prior to the
making  by the  Lenders  of any  Eurodollar  Loan  (in the  case of the  initial
Interest Period  therefor) or the expiration  date of each  succeeding  Interest
Period (in the case of subsequent  Interest  Periods  therefor),  Borrower shall
have the option, subject to compliance by Borrower with all of the provisions of
this Agreement,  as long as no Event of Default  exists,  to specify whether the
Interest  Period  commencing on any such date shall be a one (1), two (2), three
(3) or six (6) month period.  If the Agent shall not have received timely notice
of a designation of such Interest Period as herein  provided,  Borrower shall be
deemed to have  elected to convert all  maturing  Eurodollar  Loans to Base Rate
Loans.



                                       25


     SECTION 4.2.  INTEREST RATE  DETERMINATION.  The Agent shall determine each
interest  rate  applicable  to any Base  Rate  Loan or  Eurodollar  Loan and its
determination  shall be conclusive absent manifest error. The Agent shall notify
the Borrower of each interest rate determination  within a reasonable time after
each such determination.

     SECTION 4.3. CONVERSION OPTION. Borrower may elect from time to time (i) to
convert all or any part of its Eurodollar Loans to Base Rate Loans by giving the
Agent  irrevocable  notice  of such  election  in  writing  prior to 10:00  a.m.
(Lafayette,  Louisiana time) on the conversion date and such conversion shall be
made on the requested  conversion  date,  provided  that any such  conversion of
Eurodollar  Loan shall only be made on the last day of the  Eurodollar  Interest
Period  with  respect  thereof,  and (ii) to convert all or any part of its Base
Rate Loans to Eurodollar Loans by giving the Agent irrevocable written notice of
such election three (3) Business Days prior to the proposed  conversion and such
conversion shall be made on the requested  conversion date or, if such requested
conversion date is not a Business Day on the next  succeeding  Business Day. Any
such conversion  shall not be deemed a prepayment of any Note or a prepayment of
any of the Loans for purposes of this Agreement.

                                    ARTICLE V

                             CHANGE OF CIRCUMSTANCES


     SECTION 5.1. UNAVAILABILITY OF FUNDS OR INADEQUACY OF PRICING. In the event
that, in connection  with any proposed  Eurodollar  Loan, the Agent  determines,
which  determination  shall,  absent manifest  error,  be final,  conclusive and
binding upon all parties, due to changes in circumstances since the date hereof,
adequate and fair means do not exist for determining the Eurodollar Rate or such
rate will not accurately  reflect the costs to the Lenders of funding Eurodollar
Loans for such Eurodollar  Interest Period,  the Agent shall give notice of such
determination to the Borrower,  whereupon, until the Agent notifies the Borrower
that the  circumstances  giving rise to such  suspension  no longer  exist,  the
obligation  of the Lenders to make,  continue or convert  Loans into  Eurodollar
Loans shall be  suspended,  and all loans to  Borrower  shall be Base Rate Loans
during the period of suspension.

     SECTION 5.2.  CHANGE IN LAWS.  If at any time after the date hereof any new
law or any change in existing laws or in the  interpretation by any governmental
authority, central bank, or comparable agency charged with the administration or
interpretation  thereof,  of any new or existing laws shall make it unlawful for
the such  Lender  to make or  continue  to  maintain  or fund  Eurodollar  Loans
hereunder,  then such Lender shall promptly  notify  Borrower in writing of such
Lender's  obligation to make,  continue or convert Loans into  Eurodollar  Loans
under this Agreement  shall be suspended until it is no longer unlawful for such
Lender to make or  maintain  Eurodollar  Loans.  Upon  receipt  of such  notice,
Borrower  shall  either  repay  the  outstanding  Eurodollar  Loans  owed to the
Lenders,  without penalty,  on the last day of the current Interest Periods (or,
if any Lender may not  lawfully  continue to maintain  and fund such  Eurodollar
Loans,  immediately),  or Borrower  may convert  such  Eurodollar  Loans at such
appropriate time to Base Rate Loans.



                                       26


     SECTION 5.3. INCREASED COST OR REDUCED RETURN.

                    (i)  If,  after  the  date  hereof,   the  adoption  of  any
applicable law, rule, or regulation,  or any change in any applicable law, rule,
or regulation,  or any change in the interpretation or administration thereof by
any governmental authority,  central bank, or comparable agency charged with the
interpretation or administration  thereof,  or compliance by any Lender with any
request  or  directive  (whether  or not  having  the  force of law) of any such
governmental authority, central bank, or comparable agency:

                         (A) shall  subject  such  Lender to any tax,  duty,  or
                    other  charge  with  respect to any  Eurodollar  Loans,  the
                    Notes, or its obligation to make Eurodollar Loans, or change
                    the basis of taxation of any amounts  payable to such Lender
                    under  this  Agreement,  or the  Notes,  in  respect  of any
                    Eurodollar  Loans  (other  than  franchise  taxes  and taxes
                    imposed on the overall net income of such Lender);

                         (B)  shall  impose,  modify,  or  deem  applicable  any
                    reserve, special deposit, assessment, or similar requirement
                    (other than reserve requirements, if any, taken into account
                    in the determination of the Eurodollar Rate) relating to any
                    extensions  of credit or other  assets  of, or any  deposits
                    with or other  liabilities or  commitments  of, such Lender,
                    including the Commitment of such Lender hereunder; or

                         (C)  shall  impose  on  such  Lender  or on the  London
                    interbank   market  any  other   condition   affecting  this
                    Agreement or its Notes or any of such  extensions  of credit
                    or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender of
making,  converting into, continuing,  or maintaining any Eurodollar Loans or to
reduce any sum received or receivable by such Lender under this Agreement or its
Note with  respect to any  Eurodollar  Loans,  then  pursuant to Section  5.3(v)
Borrower shall pay to such Lender such amount or amounts as will compensate such
Lender  for  such  increased  cost  or  reduction.   If  such  Lender   requests
compensation  by Borrower  under this Section  5.3.,  Borrower may, by notice to
such  Lender,  suspend  the  obligation  of such  Lender  to  make  or  continue
Eurodollar  Loans, or to convert all or part of the Base Rate Loan owing to such
Lender to  Eurodollar  Loans,  until the event or condition  giving rise to such
request  ceases to be in effect (in which case the  provisions  of Section  5.3.
shall be applicable);  provided that such suspension  shall not affect the right
of such Lender to receive the compensation so requested.



                                       27


                    (ii) If,  after the date  hereof,  such  Lender  shall  have
determined  that  the  adoption  of any  applicable  law,  rule,  or  regulation
regarding  capital  adequacy or any change therein or in the  interpretation  or
administration  thereof  by  any  governmental   authority,   central  bank,  or
comparable agency charged with the interpretation or administration  thereof, or
any request or directive  regarding  capital adequacy (whether or not having the
force of law) of any such  governmental  authority,  central bank, or comparable
agency,  has or would  have the  effect  of  reducing  the rate of return on the
capital of such Lender or any corporation controlling Lender as a consequence of
such Lender's  obligations  hereunder to a level below that which such Lender or
such corporation could have achieved but for such adoption,  change, request, or
directive  (taking  into  consideration  its  policies  with  respect to capital
adequacy),  then from time to time pursuant to Section 5.3(v) Borrower shall pay
to such Lender such additional  amount or amounts as will compensate  Lender for
such reduction.

                    (iii) Each  Lender  shall  promptly  notify  Borrower of any
event of which it has  knowledge,  occurring  after the date hereof,  which will
entitle such Lender to compensation pursuant to this Section 5.3. will designate
a separate  lending office,  if applicable,  if such  designation will avoid the
need for,  or reduce the  amount  of,  such  compensation  and will not,  in the
judgment of such  Lender,  be  otherwise  disadvantageous  to it. If such Lender
claims  compensation  under this Section 5.3., such Lender shall  simultaneously
furnish to Borrower a statement  setting forth the additional  amount or amounts
to be paid to it hereunder  which shall be conclusive in the absence of manifest
error. In determining such amount, such Lender may use any reasonable  averaging
and attribution methods.

                    (iv) If any Lender gives  notice to the Borrower  (either by
Lender or through  the Agent)  pursuant to Section  5.3.  hereof,  Lender  shall
simultaneously  give to the  Borrower a  statement  signed by an officer of such
Lender setting forth in reasonable  detail the basis for, and the calculation of
such additional cost, reduced payments or capital requirements,  as the case may
be, and the additional amounts required to compensate Lender therefor.

                    (v) Within  fifteen (15) days after  receipt by the Borrower
of any notice referred to in Section 5.3., the Borrower shall pay to such Lender
such  additional  amounts as are  required  to  compensate  such  Lender for the
increased cost,  reduce  payments or increase  capital  requirements  identified
therein, as the case may be; provided,  that the Borrower shall not be obligated
to compensate such Lender for any increased costs, reduced payments or increased
capital  requirements  to the extent that such Lender incurs the same prior to a
date six (6) months before such Lender gives the required notice.

     SECTION 5.4. BREAKAGE COSTS.  Without duplication under any other provision
hereof,  if any  Lender  incurs  any actual  loss,  cost or expense  (including,
without  limitation,  any loss of profit  and loss,  cost,  expense  or  premium
reasonably incurred by reason of the liquidation or re-employment of deposits or
other funds acquired by such Lender to fund or maintain any  Eurodollar  Loan or
the relending or reinvesting of such deposits or amounts paid or prepaid to such
Lender as a result of any of the following events other than any such occurrence
as a result in the change of circumstances described in Sections 5.1. and 5.2.:



                                       28


                         (i)  any  payment,   prepayment   or  conversion  of  a
                    Eurodollar  Loan on a date  other  than  the last day of its
                    Eurodollar   Interest  Period   (whether  by   acceleration,
                    prepayment or otherwise);

                         (ii)  any  failure  to make a  principal  payment  of a
                    Eurodollar Loan on the due date thereof; or

                         (iii) any failure by the Borrower to borrow,  continue,
                    prepay  or  convert  to  a  Eurodollar  Loan  on  the  dates
                    specified in a notice given pursuant to this Agreement.

then the  Borrower  shall  within 15 days after  demand pay to such  Lender such
amount as will  reimburse  such Lender for such loss,  cost or expense.  If such
Lender makes such a claim for compensation,  it shall simultaneously  furnish to
Borrower a statement  setting forth the amount of such loss,  cost or expense in
reasonable detail (including an explanation of the basis for and the computation
of such loss,  cost or expense) and the amounts shown on such statement shall be
conclusive and binding absent manifest error.

     SECTION 5.5. DISCRETION OF LENDER AS TO MANNER OF FUNDING.  Notwithstanding
any provisions of this Agreement to the contrary,  each Lender shall be entitled
to fund and maintain its funding of all or any part of its Facility Loans in any
manner it sees fit, it being understood,  however, that for the purposes of this
Agreement all determinations  hereunder,  except as may otherwise be provided in
this  Article  V,  shall  be made as if each  Lender  had  actually  funded  and
maintained  each  Eurodollar  Loan  through the  purchase  of deposits  having a
maturity  corresponding  to  the  last  day of the  Eurodollar  Interest  Period
applicable  to  such  Eurodollar  Loan  and  bearing  an  interest  rate  to the
applicable interest rate for such Eurodollar Period.

                                   ARTICLE VI

                                      FEES

     SECTION 6.1. FACILITY FEES.

     SECTION  6.1.1.  FACILITY FEE. The Borrower  shall pay to the Agent for the
benefit of Union Bank a facility fee of one-half percent (0.50%) of Union Bank's
Pro Rata Part of  $28,000,000.00.  In addition,  Borrower shall pay to Agent for
the Pro Rata  benefit of the  Lenders an  additional  facility  fee of  one-half
percent  (0.50%) of the  incremental  amount of any  increase to the  Facility A
Borrowing Base Amount shall be owed by Borrower to the Agent, and such fee shall
be payable by Borrower upon  Borrower's  acceptance of said increase;  provided,
however,  if the Facility A Borrowing Base Amount is reduced and then reinstated
to a higher amount,  the additional  facility fee will be applicable only to the
incremental  amount,  if any, by which the higher  amount  exceeds the  previous
highest Facility A Borrowing Base Amount.  In the event the Facility B Borrowing
Base Amount  exceeds  $0.00,  the facility fee  applicable  thereto  shall be as
negotiated by the Agent and the Borrower.  The Borrower  hereby  authorizes  the
Agent to debit its  account  maintained  with  Hibernia  for  collection  of the
foregoing facility fees.



                                       29


     SECTION 6.2. UNUSED FEES.

     SECTION  6.2.1.  FACILITY A UNUSED FEE. The Borrower shall pay to the Agent
(for the Pro Rata benefit of the Lenders) an unused fee calculated on the unused
portion of the Facility A Borrowing Base Amount as follows:  (i) if the Facility
A Borrowing Base Usage is greater than or equal to 50%, the unused fee is 0.50%;
and (ii) if the Facility A Borrowing Base Usage is less than 50%, the unused fee
is 0.375%.  The unused fee will be payable  quarterly in arrears on the last day
of each fiscal quarter,  commencing December 31, 2004. The unused portion of the
Facility  A  Borrowing  Base  Amount  shall be  determined  on a daily  basis by
subtracting  from the  Facility A Borrowing  Base Amount the Total  Outstandings
under  Facility A, and by averaging  said daily amounts for the period for which
the fee is to be determined.  The Borrower hereby  authorizes the Agent to debit
its account maintained with the Hibernia for collection of the unused fee.

of any mortgage,  deed of trust, pledge, lien, security interest or other charge
or  encumbrance  of any  nature  (other  than  as  contemplated  by the  Related
Documents)  upon or with respect to any of the properties now owned or hereafter
acquired by the Borrower.  Each of the Loan  Documents and Related  Documents to
which the Borrower is a party constitutes a legal,  valid and binding obligation
of the Borrower, enforceable in accordance with its terms.

     SECTION 11.2.  FINANCIAL  STATEMENTS.  The most recent balance sheet of the
Borrower at the dates thereof, and the related statements of income and retained

the Borrower  (the  categories of exceptions in clauses (iv) through (xi), as so
qualified and as any such exceptions may exist from time to time, being referred
to as the  "DESIGNATED  TITLE  EXCEPTIONS").  The Mortgage  constitutes a legal,

there are no  judgments  or decrees  affecting  the  Borrower,  or its  property

expected to become an Encumbrance against such property (other than a Designated

Section 11.4 shall occur if the same is discharged  within thirty days after the
date of entry thereof or an appeal or appropriate  proceeding for review thereof
is taken  within  such  period and a stay of  execution  pending  such appeal is
obtained.

exemption of, nor any filing or  registration  with,  any  governmental  body or
regulatory authority (federal, state or local), and no vote, consent or approval

               electrical transformers or other equipment;

     (i) There have been no written commitments or agreements involving Borrower
from or with  any  Governmental  Authority  or any  private  entity  (including,
without  limitation,  the  owner  of the  Mortgaged  Properties  or any  portion
thereof) relating to the generation,  storage, treatment,  presence, Release, or
threatened Release which could reasonably be expected to have a Material Adverse
Effect  on or  into  any of  the  properties  of  Borrower  or  the  environment
(including off-site disposal of Hazardous Materials) or any Remedial Action with
respect thereto in non-compliance or violation of any Environmental Law;

     (j) Borrower  has not  received  any written  notice or claim to the effect
that  it is or may be  liable  to any  Person  as a  result  of the  Release  or
threatened Release which could reasonably be expected to have a Material Adverse
Effect;

     (k) To the best of  Borrower's  knowledge  and  belief  after due  inquiry,
Borrower has no known  liability  in  connection  with any  material  Release or
material  threatened  Release  which  could  reasonably  be  expected  to have a
Material Adverse Effect;

     (l) After due inquiry, no Environmental Lien has attached (and continues to
attach) to any  properties of Borrower,  provided that no breach of this Section
11.16(l)  shall  occur if the same is  discharged  within  thirty days after the
attachment  thereof  or an appeal or other  appropriate  proceeding  for  review
thereof  is taken  within  said  thirty day  period  and/or a stay of  execution
pending such appeal is obtained; and

     (m) To the Borrower's best knowledge after due inquiry,  there have been no
environmental investigations,  studies, audits, tests, reviews or other analyses
conducted  by or



                                       39


which  are in the  possession  of  Borrower  in  relation  to any  violation  of
Environmental  Laws which  violation  could  reasonably  be  expected  to have a
Material  Adverse  Effect in  relation  to any  properties  or  facility  now or
previously  owned or leased by Borrower  which have not been made  available  to
Agent.

     SECTION  11.17.  SOLVENCY  OF THE  BORROWER.  The  Borrower  is  and  after
consummation of the transactions  contemplated by this Agreement  (including the
making of the  Facility  Loans and the  issuance  of  Letters  of Credit  and/or
Hedge-Related  Letters of Credit),  and after giving  effect to all  obligations
incurred by the Borrower in connection herewith, will be, Solvent.

     SECTION 11.18. GOVERNMENTAL  REQUIREMENTS.  The Collateral is in compliance
with all current governmental  requirements affecting the said property,  except

corporation duly created,  validly existing, and in good standing under the laws
of the state of its incorporation, and is duly qualified and in good standing as
foreign  corporation  in all other  jurisdictions  where the  failure to qualify
would have an adverse effect upon its ability to perform its  obligations  under
this Agreement and all Related  Documents to which it is a party.  The Guarantor
has the  corporate  power to enter into this  Agreement  and the  Guaranty.  The
Guarantor has the power to perform its obligations  hereunder and under the Loan
Documents  and  Related  Documents  to  which  it is a  party.  The  making  and
performance  by the  Guarantor of the Loan  Documents  and Related  Documents to
which it is a party have all been duly authorized by all necessary  corporate or
company action,  and do not and will not violate any provision of any law, rule,
regulation,  order, writ, judgment, decree,  determination or award presently in
effect having  applicability to the Guarantor,  or the articles of incorporation
and bylaws of the Guarantor.  The making and performance by the Guarantor of the
Loan Documents and Related  Documents to which it is a party do not and will not
result in a breach of or  constitute a default  under any material  indenture or
loan or credit agreement or any other material  agreement or instrument to which
the Guarantor is a party or by which it may be bound or affected,  or result in,
or require,  the creation or imposition of any mortgage,  deed of trust, pledge,
lien, security interest or other charge or encumbrance of any nature (other than
as  contemplated  by the Related  Documents)  upon or with respect to any of the
properties now owned or hereafter  acquired by the Guarantor,  and the Guarantor
is not in default  under or in  violation  of any such  order,  writ,  judgment,
decree, determination,  award, indenture,  agreement or instrument to the extent
any such default or violation  could  reasonably  be expected to have a Material
Adverse  Effect.  Each of the Loan Documents and Related  Documents to which the
Guarantor is a party  constitutes a legal,  valid and binding  obligation of the
Guarantor, enforceable in accordance with its terms.

     SECTION  11.20.  SECURITIES  PURCHASE  AGREEMENT.  As of  the  date  hereof
(without giving effect to any material modifications which may hereafter be made
to this  Agreement),  (i) the  Indebtedness  existing  as of the date  hereof is
entitled  to the  benefits  accorded  the Senior  Indebtedness  (as such term is
defined  in the  Securities  Purchase  Agreement)  and (ii) the  consent  of the
Investors (as such term is defined in the Securities  Purchase Agreement) is not
required for the Borrower's execution of and performance under this Agreement.



                                       40


     SECTION 11.21.  SECURITY  AGREEMENT.  The Security Agreement  constitutes a
first priority  security  interest  affecting one hundred  percent (100%) of the
issued  and  outstanding  stock  of  the  Guarantor,  and  there  are  no  other
Encumbrances  affecting  the said stock  except for a  subordinated  Encumbrance
granted or to be granted by Borrower as  security  for the Secured  Subordinated
Debt.

     SECTION 11.22.  SECURITIES PURCHASE AGREEMENT.  The Borrower represents and
warrants that it is not in default under the Securities Purchase Agreement,  and
that no such  default  will occur as a result of  Borrower's  execution  of this
Agreement, and its incurrence of obligations hereunder.

     SECTION 11.23.  SURVIVAL OF  REPRESENTATIONS  AND WARRANTIES.  The Borrower
understands and agrees that the Agent and the Lenders are relying upon the above
representations and warranties in making the Loans to the Borrower. The Borrower
further agrees that the foregoing  representations  and warranties shall be true
and correct in all  material  respects as of the date(s) made or deemed made and
shall remain in full force and effect until such time as the Indebtedness  shall
be paid in full, or until this Agreement  shall be terminated,  whichever is the
last to occur.

                                   ARTICLE XII

     (g)  as soon as available and in any event by September  30th of each year,

Borrower,  (iii) the occurrence of a reportable  event under, or the institution

                                       42


     SECTION 12.3. MAINTENANCE OF EXISTENCE,  PROPERTIES AND LIENS. The Borrower
will  (i)  continue  to  engage  in the  Subject  Business  and  other  business
activities  reasonably related to thereto;  (ii) maintain its existence and good
standing in each  jurisdiction  in which it is required to be  qualified;  (iii)
keep and  maintain all  franchises,  licenses  and  properties  necessary in the
conduct of its  business in good order and  condition,  except to the extent the
failure to do so could not  reasonably  be expected to cause a Material  Adverse
Effect;  (iv) duly  observe  and  conform to all  material  requirements  of any
governmental  authorities  relative  to  the  conduct  of  its  business  or the
operation of its properties or assets, except to the extent the failure to do so
could not reasonably be expected to cause a Material Adverse Effect; and (v) the
Borrower  will  maintain  in favor of the Agent for the  ratable  benefit of the
Lenders a first perfected lien and security interest in the Collateral,  subject
only to Permitted Encumbrances and Designated Title Exceptions.

     SECTION 12.4.  TAXES.  The Borrower shall pay or cause to be paid when due,
all taxes, local and special assessments, and governmental charges of every type

evidence that such taxes, assessments, and governmental and other charges due by
the  Borrower  have  been paid in full and in a timely  manner,  if such data is
requested by the Agent. Notwithstanding the foregoing, the Borrower may withhold
any such  payment or elect to contest any lien if the  Borrower is in good faith
conducting an  appropriate  proceeding  to contest the  obligation to pay and so
long as the Agent's interest in the Collateral is not jeopardized.

     SECTION 12.5. INTENTIONALLY DELETED.

     SECTION 12.6 COMPLIANCE WITH ENVIRONMENTAL  LAWS. The Borrower shall comply
with and shall use reasonable  commercial efforts to cause all of its employees,
agents,  invitees or sublessees  (while such Persons are acting within the scope
of their  relationship  with the Borrower) to (i) comply with all  Environmental
Laws with respect to the disposal of Hazardous  Materials,  (ii) pay immediately
when due the cost of removal of any such Hazardous Materials, and (iii) keep the
Borrower's  properties  free of any lien imposed  pursuant to any  Environmental
Laws,  provided  that no breach of this Section 12.6 shall occur if (a) the same
is  discharged  within  thirty  (30) days  after the  Borrower  is  notified  of
non-compliance  or an appeal or  appropriate  proceedings  for review thereof is
taken  within such period and Borrower is not  obligated to comply  pending such
appeal  or other  appropriate  proceedings  or (b)  failure  to do so could  not
reasonably be expected to have a Material Adverse Effect.

     The Borrower shall give notice to the Agent as soon as reasonably  possible
and in no event more than five (5) days after it receives any compliance orders,
environmental  citations,  or  other  notices  from any  Governmental  Authority
relating  to  any  Environmental  Liabilities  relating  to  its  properties  or
elsewhere  which may  reasonably  be expected to result in a Default of Event of
Default;  the  Borrower  agrees  to take any and all  reasonable  steps,  and to
perform any and all  reasonable  actions  necessary or  appropriate  to promptly
comply  with  any  such  citations,  compliance  orders  or  Environmental  Laws
requiring the Borrower to remove,  treat or dispose of such Hazardous Materials,
and, upon Agent's request,  to provide the Agent with  satisfactory  evidence of
such compliance in excess of $500,000; provided, however, that nothing contained
herein shall preclude the Borrower from contesting any such compliance orders or
citations  if



                                       43


such contest is made in good faith, appropriate reserves are established for the
payment for the cost of compliance therewith,  and the Agent's security interest
in  any  such  property  affected  thereby  (or  the  priority  thereof)  is not
jeopardized.

     Regardless  of whether any Event of Default  hereunder  shall have occurred
and be  continuing,  the  Borrower (i) releases and waives any present or future
claims against the Agent and/or the Lenders for indemnity or contribution in the
event the Borrower  becomes liable for any  Environmental  Lien and/or  Remedial
Action,  and (ii) agrees to defend,  indemnify and hold harmless the Lender from
any  and  all  liabilities  (including  strict  liability),   actions,  demands,
penalties, losses, costs or expenses (including, without limitation,  reasonable
attorneys fees and remedial costs), suits,  administrative orders, agency demand
letters,  costs of any  settlement  or judgment and claims of any and every kind
whatsoever  which  may  now  or in the  future  (whether  before  or  after  the
termination of this  Agreement) be paid,  incurred,  or suffered by, or asserted
against the  Lenders by any person or entity or  governmental  agency for,  with
respect to, or as a direct or indirect  result of, the presence on or under,  or
the escape, seepage, leakage, spillage, discharge,  emission, or release from or
onto the property of the Borrower of any Hazardous  Materials,  regulated by any
Environmental Laws,  contamination  resulting  therefrom,  or arising out of, or
resulting   from,   the   environmental   condition  of  such  property  or  the
applicability  of  any  Environmental  Laws  relating  to  hazardous   materials
(including,  without limitation, CERCLA or any so called federal, state or local
"super fund" or "super lien" laws, statute,  ordinance,  code, rule, regulation,
order or decree) regardless of whether or not caused by or within the control of
the Lender (the costs and/or  liabilities  described in (i) and (ii) above being
hereinafter referred to as the "Environmental  Liabilities").  THE COVENANTS AND
INDEMNITIES CONTAINED IN THIS SECTION 12.6 SHALL SURVIVE THE TERMINATION OF THIS
AGREEMENT,  BUT EXCLUDING ALL INDEMNITY  MATTERS  ARISING BY REASON OF THE GROSS
NEGLIGENCE OR WILLFUL  MISCONDUCT  ON THE PART OF ANY  INDEMNIFIED  PARTY;  AND,
PROVIDED,  HOWEVER, NO RELEASE,  WAIVER,  DEFENSE OR INDEMNITY SHALL BE AFFORDED
UNDER THIS SECTION 12.6 IN RESPECT OF ANY  PROPERTY FOR ANY  OCCURRENCE  ARISING
FROM THE ACTS OR  OMISSIONS  OF THE AGENT  AND/OR THE LENDERS OR THEIR AGENTS OR
REPRESENTATIVES  DURING THE PERIOD AFTER WHICH SUCH PERSON,  ITS  SUCCESSORS  OR
ASSIGNS,  OR ITS  AGENTS OR  REPRESENTATIVES,  SHALL  HAVE  OBTAINED  OWNERSHIP,
OPERATION OR POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU
OF FORECLOSURE,  AS MORTGAGEE-IN-POSSESSION OR OTHERWISE). ANY CLAIMS UNDER THIS
SECTION 12.6 SHALL BE SUBJECT TO SECTION 15.9.

     SECTION 12.7. FURTHER  ASSURANCES.  The Borrower will, at any time and from
time to time, execute and deliver such further instruments and take such further
action as may reasonably be requested by the Agent, in order to cure any defects
in the execution and delivery of, or to comply with or accomplish  the covenants
and agreements contained in this Agreement or the Collateral Documents.

     SECTION  12.8.  FINANCIAL  COVENANTS.  The  Borrower  shall comply with the
following covenants and ratios:



                                       44


     (a)  MINIMUM  CURRENT  RATIO.  The Borrower  shall at all times  maintain a
          minimum Current Ratio of 1.0 to 1.0.

     (b)  MAXIMUM  TOTAL  RECOURSE  DEBT TO EBITDA  RATIO.  The  Borrower  shall
          maintain at all times a ratio of Total  Recourse Debt to EBITDA of not
          more than 3.00 to 1.0,  calculated on a rolling four  quarters  basis.
          For the  purposes of this  covenant,  EBITDA shall not include the net
          revenue   attributable  to  assets  pledged  to  secure   Non-Recourse
          Indebtedness.  The term "Total  Recourse  Debt" shall mean  Borrower's
          consolidated Debt excluding  Non-Recourse  Indebtedness and Debt of an
          Unrestricted Subsidiary.

     (c)  MINIMUM  QUARTERLY  DEBT SERVICE  COVERAGE  RATIO.  The Borrower shall
          maintain  at the end of each  quarter a Debt  service  coverage  ratio
          (excluding Non-Recourse Indebtedness of Unrestricted  Subsidiaries) of
          not less than 1.25 to 1.0. For purposes of this covenant, the non-cash
          effects,  if any, of Hedging Agreements  pursuant to SFAS 133 will not
          be included,  nor will the effect, if any, of ceiling test write-downs
          pursuant  to  Regulation   SX4.10  of  the   Securities  and  Exchange
          Commission  be included.  Debt service  coverage  shall be  calculated
          based  on GAAP as  follows:  the  ratio of (a) the  difference  of (i)
          EBITDA for the quarter just ended (excluding  EBITDA related to assets
          pledged to secure  Non-Recourse  Indebtedness),  minus (ii)  permitted
          cash dividends paid during the quarter just ended,  divided by (b) the
          sum of (i)  required  principal  and  interest  paid  in  cash  on the
          Indebtedness  during the quarter just ended,  plus (ii) all  principal
          and interest paid in cash on Debt other than the  Indebtedness  during
          the quarter just ended, plus (iii) the positive difference, if any, of
          (x) principal and interest paid in cash on  Non-Recourse  Indebtedness
          during the quarter just ended,  minus (y) positive  EBITDA  related to
          assets pledged to secure Non-Recourse  Indebtedness during the quarter
          just ended.

     (d)  MINIMUM SHAREHOLDER'S EQUITY. The Borrower shall maintain at all times
          a minimum shareholder's equity of not less than $100,000,000.00,  plus
          (i)  100%  of  all  common  and  preferred   equity   contributed   by
          shareholders of Borrower ("Equity  Issuances")  subsequent to June 30,
          2004, plus (ii) 50% of all positive earnings  occurring  subsequent to
          June 30, 2004,  plus (iii) 180 days after  Borrower's  issuance of the
          Secured  Subordinated  Debt  (the  "Secured  Subordinated  Debt  Issue
          Date"), an amount equal to the difference,  if positive, of (a) 50% of
          the net proceeds  from the issuance of the Secured  Subordinated  Debt
          less  (b) 100% of all  common  and  preferred  equity  contributed  by
          shareholders   of  Borrower  from  the  date  hereof  to  the  Secured
          Subordinated  Debt Issue  Date.  For  purposes of this  covenant,  the
          calculation  of  Borrower's  "shareholder's  equity"  will exclude the
          effects,  if any, of ceiling test  write-downs  pursuant to Regulation
          SX4.10 of the Securities and Exchange Commission.

     SECTION 12.9.  OPERATIONS.  The Borrower shall conduct its business affairs
in a  reasonable  and  prudent  manner  and in  compliance  with all  applicable
federal, state and municipal laws, ordinances,  rules and regulations respecting
its properties,  charters, businesses and operations,  including compliance with
all minimum funding standards and other requirements of ERISA of 1974, and other
laws applicable to any employee benefit plans which they may have, except to



                                       45


the extent the  failure to do so could not  reasonably  be  expected  to cause a
Material Adverse Effect.

     SECTION  12.10.  CHANGE OF LOCATION.  The Borrower  shall,  within ten (10)
Business  Days  prior to any such  change,  notify  the Agent in  writing of any
proposed change in the location of its chief executive office.

     SECTION  12.11.  EMPLOYEE  BENEFIT  PLANS.  The Borrower will maintain each
employee  benefit  plan as to  which  it may have  any  liability,  in  material
compliance with all applicable requirements of law and regulations.

     SECTION 12.12.  DEPOSIT AND OPERATING ACCOUNTS.  The Borrower will maintain
its primary  operating and savings  accounts with the Lenders (or one or more of
them).

     SECTION 12.13. PRODUCTION PROCEEDS.  Subject to the terms and conditions of
the  Mortgage,  the  Borrower  will cause all  production  proceeds and revenues
attributable  to the  Mortgaged  Properties  to be  paid  and  deposited  in the
Borrower's  accounts  maintained with a Lender,  and shall not redirect  initial
deposit of such proceeds to any other accounts.

     SECTION 12.14.  FIELD AUDITS;  OTHER  INFORMATION.  Upon  reasonable  prior
notice,  the Borrower shall allow the Agent's employees and agents access to its
books and records and properties  during normal  business hours to perform field
audits  from  time to time.  The  Borrower  shall pay all  reasonable  costs and
expenses  associated with such field audits. The Borrower will provide the Agent
with such other  information  as the Agent may  reasonably  request from time to
time,  subject  in all  cases to any  confidentiality  restrictions  that may be
applicable  to the  Borrower  and its  Subsidiaries  and to any  confidentiality
restrictions that the Borrower  reasonably imposes on the Persons receiving such
information;  provided,  however,  that  neither  the  Borrower  nor  any of its
Subsidiaries   shall  be  required  to  disclose  to  Agent  or  any  agents  or
representatives  thereof any information which is the subject of attorney-client

transaction  is on terms  that are no less  favorable  to the  Borrower  or such
Subsidiary, as the case may be, than those that could be obtained at the time of
such transaction on an arm's-length  basis from a Person who is not an affiliate
and if  such  transaction  involves  an  amount  in  excess  of  $500,000,  such
transaction  has been  approved  by a  majority  of the  members of the Board of
Directors  of the  Borrower  having  no  personal  stake  in  such  transaction;
provided,  however,  that this Section 13.8 (i) shall not apply to  transactions
between a  Subsidiary  and the  Borrower  or any other  Subsidiary,  or  between
Pinnacle Gas  Resources,  Inc. and the Borrower or a Subsidiary,  (ii) shall not
prohibit any person serving as an officer,  director,  employee or consultant of
the  Borrower or any  Subsidiary  from (A)  receiving  reasonable  compensation,



                                       53


benefits  or  indemnification  in  connection  with his or her  services in such
capacity  (except  as  otherwise  included  hereby),   provided  that  any  such
compensation,  benefits  or  indemnification  are  approved by a majority of the
disinterested  members  of the  Board of  Directors  of the  Borrower  or by the
Compensation  Committee of the Borrower,  (B)  receiving  advances for travel or
other  business  expenses  made  in  the  ordinary  course  of  business  or (C)
participating in any benefit or compensation  plan; and (iii) shall not restrict
the Borrower  from  repaying to any director or its  affiliates  when due on its
scheduled  maturity dates any  indebtedness  for borrowed money  permitted to be
incurred in accordance with this Agreement.

     SECTION 13.9. USE OF FACILITY LOAN PROCEEDS. The Borrower shall not use any
Facility Loan proceeds to finance investments in marketable securities.

     SECTION 13.10.  COMMODITY  TRANSACTIONS.  The Borrower shall not enter into
any speculative commodity transactions of any type or Hedging Agreement relating
to the sale of  aggregate  Hydrocarbons  production  in  excess  of  eighty-five
percent  (85%) of the total  volume  of such  production  projected  in the most
recent independent engineering report delivered to the Agent pursuant to Section
12.1(e) or as  projected  in the most  recent  internally  prepared  engineering
report  delivered to the Agent  pursuant to Section  12.1(g),  whichever is more
recent, to come from the Borrower's proved developed  producing  reserves during
the term of such Hedging Agreement.  Notwithstanding the foregoing,  the maximum
duration of any permitted  Hedging  Agreement shall not exceed  twenty-four (24)
months.  In  addition,  if  Borrower  desires to enter into  Hedging  Agreements
affecting  new  wells  that  are not  included  in the most  recently  delivered
engineering  report,  Borrower  agrees to obtain  the  Required  Lenders'  prior
written  consent  to  such  Hedging  Agreements,  which  consent  shall  not  be
unreasonably withheld.

     SECTION 13.11.  PAYMENTS ON SECURED SUBORDINATED DEBT. Subject to the terms
and conditions of the subordination  agreement referenced in Section 10.2 above,
the Borrower agrees that the only scheduled payments on the Secured Subordinated
Debt will be scheduled  interest payments on promissory notes evidencing Secured
Subordinated Debt so long as the Line of Credit is in effect.  In addition,  the
Borrower  agrees  to the  extent  it has the  discretion  to do so, to make said
interest  payments by the issuance of debt or equity  securities  to the maximum
extent permitted by the documents evidencing the Secured Subordinated Debt.

     SECTION 13.12.  PAYMENTS ON PERMITTED  SUBORDINATED  PROMISSORY  NOTES. The
Borrower  and the  Lenders  agree  that the  Borrower  is  permitted  to pay the
Subordinated  Promissory Notes pursuant to the terms of the Securities  Purchase
Agreement  and the  Memorandum,  and the Borrower  agrees to observe all payment
restrictions applicable to the Subordinated Promissory Notes as set forth in the
Securities Purchase Agreement.  Further, the Borrower agrees to exercise (to the
maximum  extent  permitted by the  Securities  Purchase  Agreement) its right to
defer all or any portion of the interest accrued on the Subordinated  Promissory
Notes as provided by Section 3.3(a) of the Securities Purchase Agreement.

                                   ARTICLE XIV

                                EVENTS OF DEFAULT

     SECTION 14.1.  EVENTS OF DEFAULT.  The occurrence of any one or more of the
following shall constitute an Event of Default:

     (a) DEFAULT  UNDER THE  INDEBTEDNESS.  Should the  Borrower  default in the
payment of principal under the  Indebtedness of the Borrower to the Lenders,  or
should the Borrower default in the payment of interest under the Indebtedness of
the Borrower to the Lender within ten (10) days after any such interest  payment
is due.

     (b) DEFAULT UNDER THIS  AGREEMENT.  Should the Borrower  violate or fail to
comply fully with any of the terms and  conditions  of, or default  under,  this
Agreement,  and  such  default  not be  cured  within  thirty  (30)  days of the
occurrence  thereof (provided,  however,  that no cure period shall be available
for a  default  in the  obligation  to  maintain  insurance  coverages  required
hereby).

     (c) DEFAULT  UNDER OTHER  AGREEMENTS.  Should any event of default occur or
exist  under any of the  Related  Documents  or should the  Borrower  and/or the
Guarantor violate, or fail to comply fully with, any terms and conditions of any
of the Collateral Documents or Related Documents,  and such default not be cured
within ten (10) days of the occurrence thereof.

     (d) OTHER DEFAULTS IN FAVOR OF THE LENDERS.  Should the Borrower and/or the
Guarantor default under any other loan, extension of credit, security agreement,
or other  obligation  in favor of any of the  Lenders  and fail to cure  same in
accordance with any applicable cure periods.

     (e) DEFAULT IN FAVOR OF THIRD PARTIES. Should the Borrower or the Guarantor
(i) fail to pay Debt  having a  principal  amount in excess of  $250,000  in the
aggregate  (other  than the  amounts  referred  to in Section  14.1(a)),  or any
interest  or premium  thereon,  when due (or, if  permitted  by the terms of the
relevant document,  within any applicable grace period), whether such Debt shall
become due by scheduled maturity,  by required prepayment,  by acceleration,  by
demand or otherwise;  or (ii) fail to perform any term, covenant or condition on
its part to be performed under any agreement or instrument evidencing,  securing
or  relating  to Debt  having a  principal  amount in excess of  $250,000 in the
aggregate,  when required to be performed, and such failure shall continue after
the applicable grace period, if any,  specified in such agreement or instrument,
if the  effect of such  failure  is to  accelerate,  or to permit  the holder or
holders of such Debt to accelerate, the maturity of such Debt.

     (f) INSOLVENCY.  The following  occurrences,  in addition to the failure or
suspension of the Borrower, shall constitute an Event of Default hereunder:

          (i)  Filing  by the  Borrower  and/or  the  Guarantor  of a  voluntary
               petition  or  any  answer  seeking  reorganization,  arrangement,
               readjustment  of its  debts or for any  other  relief  under  any
               applicable  bankruptcy act or law, or under any other  insolvency
               act or law,  now or  hereafter  existing,  or any  action  by the
               Borrower  and/or the



                                       55

               such  petition or  proceeding;  the  application  by the Borrower
               and/or  the  Guarantor  for,  or the  appointment  by  consent or
               acquiescence of, a receiver or trustee of the Borrower and/or the
               Guarantor  for all or a  substantial  part of the property of the
               Borrower and/or the Guarantor;  the making by the Borrower and/or
               the Guarantor, of an assignment for the benefit of creditors; the
               inability of the Borrower  and/or the  Guarantor or the admission
               by the Borrower and/or the Guarantor in writing, of its inability
               to pay its debts as they  mature (the term  "acquiescence"  means
               the  failure to file a petition or motion in  opposition  to such
               petition  or  proceeding  or to vacate or  discharge  any  order,
               judgment or decree  providing for such  appointment  within sixty
               (60) days after the appointment of a receiver or trustee); or

          (ii) Filing of an involuntary petition against the Borrower and/or the
               Guarantor in bankruptcy or seeking  reorganization,  arrangement,
               readjustment  of its  debts or for any  other  relief  under  any
               applicable  bankruptcy act or law, or under any other  insolvency
               act or law, now or hereafter  existing and such petition  remains
               undismissed  or  unanswered  for a period of sixty (60) days from
               such  filing;  or the  insolvency  appointment  of a receiver  or
               trustee  of  the  Borrower  and/or  the  Guarantor  for  all or a
               substantial  part of the  property  of the  Borrower  and/or  the
               Guarantor and such appointment remains unvacated or unopposed for
               a period of sixty (60) days from such  appointment,  execution or
               similar process  against any substantial  part of the property of
               the  Borrower  and/or  the  Guarantor  and such  warrant  remains
               unbonded  or  undismissed  for a period  of sixty  (60) days from
               notice to the Borrower or the Guarantor of its issuance.

     (g)  DISSOLUTION  PROCEEDINGS.  Should  proceedings  for the dissolution or
appointment of a liquidator of the Borrower and/or the Guarantor be commenced.

     (h) FALSE STATEMENTS. Should any representation or warranty of the Borrower
made by the  Borrower to the Agent  and/or the Lenders in this  Agreement or any
other Loan  Document or in any  certificate  or statement  furnished  thereunder
prove to be  incorrect  or  misleading  in any  material  respect  when  made or
reaffirmed.

          Upon the  occurrence  of an Event of Default,  the Line of Credit Loan
Commitment will, at the option of the Lenders,  either terminate or be suspended
(including  any  obligation  to make any further  Facility  Loans),  and, at the
Lenders'  option,  the Notes and all  Indebtedness  of the Borrower  will become
immediately  due and payable,  all without  notice of any kind to the  Borrower,
except that in the case of type described in the "Insolvency"  subsection above,
such  acceleration  shall be automatic and not optional.  For any other Event of
Default,  the Agent,  upon request of the Required  Lenders,  shall by notice to
Borrower  declare the  principal of, and all interest then accrued on, the Notes
and any other liabilities  hereunder to be forthwith due and payable,  whereupon
the same shall  forthwith  become due and payable without  presentment,  demand,
protest, notice of intent to accelerate,  notice of acceleration or other notice
of any kind, all of which Borrower and each Guarantor  hereby  expressly  waive,
anything contained herein or in the Notes to the contrary notwithstanding.  Upon
the  occurrence  of an Event of Default  and upon the  request  of the  Required
Lenders, the Agent shall exercise any and all rights and



                                       56


remedies under the Loan Documents, or any of them, granted to Agent hereunder or
granted to Agent at law or in equity, including, without limitation, foreclosure
of the  Collateral.  Nothing  contained in this Article 14 shall be construed to
limit or amend in any way the Events of Default  enumerated  in the Notes or any
other Loan  Document,  or any other  document  executed in  connection  with the
transaction contemplated herein.

     Upon the occurrence and during the continuance of any Event of Default, the
Lenders are hereby authorized at any time and from time to time,  without notice
to Borrower or Guarantor (any such notice being expressly waived by Borrower and
Guarantor),  to set-off and apply any and all deposits (general or special, time
or demand,  provisional or final) at any time held and other indebtedness at any
time owing by any of the Lenders to or for the credit or the account of Borrower
against any and all of the indebtedness of Borrower under the Notes and the Loan
Documents, including this Agreement,  irrespective of whether or not the Lenders
shall have made any demand under the Loan Documents, including this Agreement or
the Notes and although such indebtedness may be unmatured. Any amount set-off by
the  Lenders  shall be applied  against  the  indebtedness  owed the  Lenders by
Borrower pursuant to this Agreement and the Notes. The Lenders agree promptly to
notify Borrower after any such setoff and application, provided that the failure
to  give  such  notice  shall  not  affect  the  validity  of such  set-off  and
application.  The rights of the  Lenders  under this  Section are in addition to
other  rights and  remedies  (including,  without  limitation,  other  rights of
set-off) which the Lenders may have.

     SECTION 14.2.  WAIVERS.  Except as otherwise provided for in this Agreement
and by  applicable  law,  the  Borrower  and the  Guarantor  waive to the extent
permitted by applicable  law (i)  presentment,  demand and protest and notice of
presentment,  dishonor, notice of intent to accelerate,  notice of acceleration,
protest,  default,  nonpayment,   maturity,  release,  compromise,   settlement,
extension or renewal of any or all commercial paper, accounts,  contract rights,
documents,  instruments,  chattel  paper and  guaranties at any time held by the
Agent for the benefit of the Lenders on which the Borrower and the Guarantor may
in any way be liable and hereby ratify and confirm whatever the Agent and/or the
Lenders may do in this regard,  (ii) all rights to notice and a hearing prior to
the  Agent's  taking  possession  or  control  of,  or to the  Agent's  replevy,
attachment or levy upon,  the  Collateral or any bond or security which might be
required  by any  court  prior to  allowing  the  Agent to  exercise  any of its
remedies, and (iii) the benefit of all valuation,  appraisal and exemption laws.
The  Borrower  and the  Guarantor  acknowledge  that they have been  advised  by
counsel of their choice with  respect to this  Agreement,  the other  Collateral
Documents, and the transactions evidenced by this Agreement and other Collateral
Documents.

     SECTION 14.3. NOTICE TO DELTA FARMS LESSORS.  Borrower and Guarantor hereby
authorize  and direct  Agent to provide the lessors of the oil,  gas and mineral
leases granted by Delta Farms to the Borrower (the "Delta Farms Lessors") with a
copy of any notice of the  occurrence  of any Event of Default  which  Agent may
choose or be required to send to Borrower and/or  Guarantor under the Agreement.
Borrower and Guarantor  hereby  release Agent and the Lenders and hold Agent and
the  Lenders  harmless  from any  liability  occasioned  by the giving of or the
failure to give any such notice,  it being  understood  that Agent shall use its
best efforts to provide such notice to the Delta Farms  Lessors,  but shall have
no  obligation  or  liability  to Delta Farms  Lessors



                                       57


for its failure to do so. Under no  circumstances  shall Delta Farms  Lessors be
considered as a third party beneficiary of this Agreement.


                                   ARTICLE XV

                            THE AGENT AND THE LENDERS

     SECTION 15.1.  APPOINTMENT AND  AUTHORIZATION.  Each Lender hereby appoints
Agent as its  nominee and agent,  in its name and on its  behalf:  (i) to act as
nominee for and on behalf of such Lender in and under all Loan  Documents;  (ii)
to arrange the means  whereby the funds of Lenders are to be made  available  to
Borrower under the Loan Documents; (iii) to take such action as may be requested
by any Lender  under the Loan  Documents  (when such  Lender is entitled to make
such request under the Loan Documents);  (iv) to receive all documents and items
to be  furnished  to Lenders  under the Loan  Documents;  (v) to be the  secured
party, mortgagee,  beneficiary, and similar party in respect of, and to receive,
as the case may be, any collateral for the benefit of Lenders;  (vi) to promptly
distribute  to each Lender all material  information,  requests,  documents  and
items  received  from  Borrower  under  the Loan  Documents;  (vii) to  promptly
distribute  to each  Lender  such  Lender's  Pro Rata  Part of each  payment  or
prepayment (whether  voluntary,  as proceeds of insurance thereon, or otherwise)
in accordance  with the terms of the Loan Documents and (viii) to deliver to the
appropriate  Persons  requests,  demands,  approvals and consents  received from
Lenders. Each Lender hereby authorizes Agent to take all actions and to exercise
such powers under the Loan Documents as are specifically delegated to such Agent
by the terms  hereof or  thereof,  together  with all  other  powers  reasonably
incidental  thereto.  With respect to its  commitments  hereunder  and the Notes
issued to it, Agent and any successor Agent shall have the same rights under the
Loan  Documents  as any other Lender and may exercise the same as though it were
not the Agent;  and the term  "Lender"  or  "Lenders"  shall,  unless  otherwise
expressly indicated,  include Agent and any successor Agent in its capacity as a
Lender.  Agent and any successor  Agent and its affiliates  may accept  deposits
from, lend money to, act as trustee under  indentures of and generally engage in
any kind of business  with  Borrower,  and any Person which may do business with
Borrower,  all as if Agent and any successor  Agent were not Agent hereunder and
without any duty to account  therefor to the Lenders except where the actions of
Borrower in connection  therewith would constitute a Default or Event of Default
under this Agreement or any other Loan Document;  provided that, if any payments
in respect of any  property  (or the  proceeds  thereof) now or hereafter in the
possession  or  control  of  Agent  which  may be or  become  security  for  the
obligations  of  Borrower  arising  under  the Loan  Documents  by reason of the
general  description  of  indebtedness  secured or of property  contained in any
other  agreements,  documents or instruments  related to any such other business
shall be applied to reduction of the  obligations of Borrower  arising under the
Loan Documents,  then each Lender shall be entitled to share in such application
according to its Pro Rata part thereof.  Each Lender,  upon request of any other
Lender,  shall disclose to all other Lenders all  indebtedness  and liabilities,
direct  and  contingent,  of  Borrower  to such  Lender  as of the  time of such
request.



                                       58


     SECTION  15.2.  NOTE HOLDERS.  From time to time as other Lenders  become a
party to this  Agreement  after  receiving the consent of Borrower,  Agent shall
obtain  execution by Borrower of additional  Notes in amounts  representing  the
Commitments  of each such new Lender.  The  obligation  of such Lender  shall be
governed by the provisions of this Agreement,  including but not limited to, the
obligations specified in Article II hereof. From time to time, Agent may require
that the Lenders  exchange  their Notes for newly issued Notes to better reflect
the  Commitments  of the  Lenders.  Agent may treat the payee of any Note as the
holder  thereof until written  notice of transfer has been filed with it, signed
by such payee and in form reasonably satisfactory to Agent.

     SECTION  15.3.  CONSULTATION  WITH  COUNSEL.  Lenders  agree that Agent may
consult  with legal  counsel  selected  by Agent and shall not be liable for any
action taken or suffered in good faith by it in accordance  with and in reliance
upon the advice of such counsel.

     SECTION 15.4. DOCUMENTS. Agent shall not be under a duty to examine or pass
upon the validity, effectiveness, enforceability, genuineness or value of any of
the Loan  Documents  or any other  instrument  or  document  furnished  pursuant
thereto or in connection  therewith,  and Agent shall be entitled to assume that
the same are valid, effective,  enforceable and genuine and what they purport to
be.

     SECTION 15.5.  RESIGNATION OR REMOVAL OF AGENT.  Subject to the appointment
and acceptance of a successor Agent as provided  below,  Agent may resign at any
time by giving written notice thereof to Lenders and Borrower,  and Agent may be
removed at any time with or without cause by Lenders.  If no successor Agent has
been so appointed by Lenders (and  approved by Borrower)  and has accepted  such
appointment  within  30 days  after  the  retiring  Agent's  giving of notice of
resignation  or removal of the retiring  Agent,  then the retiring Agent may, on
behalf of  Lenders,  appoint a  successor  Agent.  Any  successor  Agent must be
approved by Borrower, which approval will not be unreasonably withheld. Upon the
acceptance of any  appointment  as Agent  hereunder by a successor  Agent,  such
successor Agent shall thereupon succeed to and become vested with all the rights
and duties of the retiring  Agent,  and the retiring  Agent shall be  discharged
from its duties and  obligations  hereunder from and after the date on which the
successor Agent accepts its appointment.  After any retiring Agent's resignation
or removal  hereunder as Agent, the provisions of this Article XV shall continue
in effect for its benefit in respect to any actions taken or omitted to be taken
by it while it was acting as Agent.

     SECTION  15.6.  RESPONSIBILITY  OF AGENT.  It is expressly  understood  and
agreed that the  obligations  of Agent under the Loan  Documents  are only those
expressly  set forth in the Loan  Documents,  or as may be imposed by applicable
law,  and that  Agent,  as the case may be,  shall be entitled to assume that no
Default or Event of Default has occurred and is continuing, unless Agent, as the
case may be, has actual  knowledge  of such fact or has  received  notice from a
Lender or Borrower  that such Lender or Borrower  consider  that a Default or an
Event of Default  has  occurred  and is  continuing  and  specifying  the nature
thereof.  Neither  Agent  nor any of their  directors,  officers,  attorneys  or
employees  shall be liable for any  action  taken or omitted to be taken by them
under or in  connection  with the Loan  Documents,  except  for its or their own
gross negligence or willful misconduct.  Agent shall incur no liability under or
in respect of any of the Loan  Documents  by acting  upon any  notice,  consent,
certificate,  warranty or other paper or



                                       59


instrument  believed  by it to be  genuine or  authentic  or to be signed by the
proper party or parties,  or with respect to anything which it may do or refrain
from doing in the reasonable  exercise of its judgment,  or which may seem to it
to be necessary or desirable.

     Agent  shall not be  responsible  to Lenders for any of  Borrower's  or any
Guarantor's recitals, statements, representations or warranties contained in any
of the Loan Documents,  or in any  certificate or other document  referred to or
provided for in, or received by any Lender under, the Loan Documents, or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of or
any of the Loan  Documents  or for any failure by Borrower or any  Guarantor  to
perform  any of their  obligations  hereunder  or  thereunder.  Agent may employ
agents and attorneys-in-fact and shall not be answerable,  except as to money or
securities  received  by it or its  authorized  agents,  for the  negligence  or
misconduct  of  any  such  agents  or  attorneys-in-fact  selected  by  it  with
reasonable care.

     The  relationship  between  Agent and each Lender is only that of agent and
principal  and has no  fiduciary  aspects.  Nothing  in the  Loan  Documents  or
elsewhere  shall be construed to impose on Agent any duties or  responsibilities
other than those for which express  provision is therein made. In performing its
duties and functions hereunder, Agent does not assume and shall not be deemed to
have assumed, and hereby expressly  disclaims,  any obligation or responsibility
toward or any relationship of agency or trust with or for Borrower or any of its
beneficiaries or other creditors.  As to any matters not expressly  provided for
by the Loan Documents, Agent 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 all Lenders  and such  instructions  shall be binding  upon all
Lenders and all holders of the Notes; provided, however, that Agent shall not be
required  to take  any  action  which  is  contrary  to the  Loan  Documents  or
applicable law.

     Agent shall have the right to exercise or refrain from exercising,  without
notice or  liability to the Lenders  (except as  otherwise  provided for in this
Agreement or by applicable  law), any and all rights  afforded to Agent,  as the
case may be, by the Loan  Documents  or which Agent may have as a matter of law;
provided,  however,  Agent shall not,  without the consent of Lenders,  take any
other  action with regard to amending  the Loan  Documents,  waiving any default
under the Loan  Documents  or taking any other  action with  respect to the Loan
Documents  which requires  consent of the Required  Lenders.  Provided  further,
however,  that no amendment,  waiver, or other action shall be effected pursuant
to the preceding  sentence  without the consent of all Lenders which:  (i) would
increase  the  Commitment  amount of any  Lender,  (ii)  would  reduce  any fees
hereunder,  or the principal of, or the interest on, any Lender's  Notes,  (iii)
would  postpone  any date fixed for any  payment of any fees  hereunder,  or any
principal or interest of any Lender's  Notes,  (iv) would  increase any Lender's
obligations  hereunder or would  materially  alter  Agent's  obligations  to any
Lender  hereunder,  (v) would release  Borrower  from its  obligation to pay any
Lender's Notes, (vi) would release the Guaranty and/or the Collateral,  or (vii)
would amend this  sentence.  For purposes of this  paragraph,  a Lender shall be
deemed to have  consented  to any such  action by Agent upon the passage of five
(5)  Business  Days after  written  notice  thereof  is given to such  Lender in
accordance with Section 16.2.  hereof,  unless such Lender shall have previously
given Agent notice,  complying with the provision of Section 16.2 hereof, to the
contrary.  Agent  shall not have  liability  to Lenders  for failure or delay in
exercising any right or



                                       60


power possessed by Agent pursuant to the Loan Documents or otherwise unless such
failure or delay is caused by the gross negligence of the Agent.

     SECTION 15.7. INDEPENDENT  INVESTIGATION.  Each Lender severally represents
and  warrants to Agent that it has made its own  independent  investigation  and
assessment of the financial condition and affairs of Borrower in connection with
the making and  continuation of its  participation  hereunder and has not relied
exclusively  on any  information  provided to such Lender by Agent in connection
herewith,  and each Lender represents,  warrants and undertakes to Agent that it
shall continue to make its own independent appraisal of the credit worthiness of
Borrower  while the Notes are  outstanding or its  commitments  hereunder are in
force. Agent shall not be required to keep itself informed as to the performance
or observance by Borrower of this Agreement or any other document referred to or
provided for herein or to inspect the  properties  or books of  Borrower.  Other
than as provided in this Agreement or any other Loan  Document,  Agent shall not
have any duty, responsibility or liability to provide any Lender with any credit
or other information concerning the affairs,  financial condition or business of
Borrower which may come into the possession of Agent.

     SECTION 15.8.  INDEMNIFICATION.  Lenders agree to indemnify Agent,  ratably
according  to their  respective  Line of Credit  Loan  Commitment  on a Pro Rata
basis, from and against any and all liabilities,  obligations,  losses, damages,
penalties,  actions,  judgments,  suits, costs, expenses or disbursements of any
proper  and  reasonable  kind or  nature  whatsoever  which may be  imposed  on,
incurred by or asserted  against  Agent in any way relating to or arising out of
the Loan  Documents  or any  action  taken or  omitted  by Agent  under the Loan
Documents,  provided  that no Lender  shall be liable  for any  portion  of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or  disbursements  resulting  from Agent's gross  negligence or
willful misconduct.  Each Lender shall be entitled to be reimbursed by the Agent
for any amount such Lender paid to Agent under this Section  15.8. to the extent
the Agent has been reimbursed for such payments by Borrower or any other Person.
THE PARTIES  INTEND FOR THE  PROVISIONS  OF THIS SECTION TO APPLY TO AND PROTECT
THE AGENT FROM THE  CONSEQUENCES  OF ANY LIABILITY  INCLUDING  STRICT  LIABILITY
IMPOSED OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF
ITS OWN NEGLIGENCE,  WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING OR
CONCURRING CAUSE OF ANY SUCH LIABILITY EXCLUDING,  HOWEVER,  GROSS NEGLIGENCE OF
AGENT.

     SECTION  15.9.  BENEFIT OF ARTICLE  XV. The  agreements  contained  in this
Article XV are solely for the  benefit of Agent and the  Lenders and are not for
the benefit of, or to be relied upon by, Borrower,  any affiliate of Borrower or
any other  person  and shall not create any  third-party  beneficiary  rights in
favor of any Person other than the Agent and the Lenders.

     SECTION  15.10.  PRO RATA  TREATMENT.  Subject  to the  provisions  of this
Agreement, each payment (including each prepayment) by Borrower or any Guarantor
and collection by Lenders (including offsets) on account of the principal of and
interest  on the Notes  and fees  provided  for in this  Agreement,  payable  by
Borrower or any  Guarantor  shall be made Pro Rata;  provided,  however,  in the
event  that  any  Defaulting  Bank  shall  have  failed  to make an  Advance  as
contemplated  in this  Agreement  hereof and Agent or another  Lender or Lenders
shall have made such Advance,  payment received by Agent for the account of such
Defaulting  Bank(s) shall not


                                       61


be distributed to such  Defaulting  Bank(s) until such Advance or Advances shall
have been  repaid in full to the Lender or Lenders  who funded  such  Advance or
Advances.

     SECTION 15.11.  ASSUMPTION AS TO PAYMENTS.  Except as specifically provided
herein,  unless Agent shall have received notice from Borrower prior to the date
on which any payment is due to Lenders  hereunder  that  Borrower  will not make
such  payment in full,  Agent may,  but shall not be  required  to,  assume that
Borrower  has made such  payment in full to Agent on such date and Agent may, in
reliance upon such  assumption,  cause to be  distributed to each Lender on such
due date an  amount  equal to the  amount  then due such  Lender.  If and to the
extent  Borrower  shall not have so made  such  payment  in full to Agent,  each
Lender shall repay to Agent forthwith on demand such amount  distributed to such
Lender together with interest thereon, for each day from the date such amount is
distributed  to such  Lender  until the date such  Lender  repays such amount to
Agent,  at the interest rate  applicable to such portion of the Revolving  Loan.
Any payment due from any lender to Agent pursuant  hereto shall bear interest at
the Federal Funds Rate

     SECTION 15.12.  OTHER FINANCINGS.  Without limiting the rights to which any
Lender otherwise is or may become entitled,  such Lender shall have no interest,
by virtue of this Agreement or the Loan Documents,  in (a) any present or future
loans  from,  letters  of  credit  issued  by,  or  leasing  or other  financial
transactions  by, any other  Lender to, on behalf  of, or with  Borrower  or any
Guarantor (collectively referred to herein as "Other Financings") other than the
obligations  hereunder;  (b) any  present  or  future  guarantees  by or for the
account of  Borrower or any  Guarantor  which are not  contemplated  by the Loan
Documents;  (c) any present or future  property  taken as security  for any such
Other  Financings  to the extent  not also  security  for the Loans;  or (d) any
property now or hereafter in the possession or control of any other Lender which
may be or become  security  for the  obligations  of Borrower  or any  Guarantor
arising  under  any loan  document  by  reason  of the  general  description  of
indebtedness secured or property contained in any other agreements, documents or
instruments  relating  to any  such  Other  Financings  to the  extent  not also
security for the Loans.

     SECTION 15.13. INTERESTS OF THE LENDERS. Nothing in this Agreement shall be
construed  to create a  partnership  or joint  venture  between  Lenders for any
purpose.  Agent, Lenders and Borrower recognize that the respective  obligations
of Lenders under the Revolving Loan  Commitments  shall be several and not joint
and that neither  Agent,  nor any of Lenders shall be  responsible  or liable to
perform any of the obligations of the other Lenders under this  Agreement.  Each
Lender is deemed to be the owner of an undivided  interest in and to all rights,
titles,  benefits  and  interests  belonging  and  accruing  to Agent  under the
Security  Instruments,   including,   without  limitation,  Liens  and  security
interests in any  Collateral,  fees and  payments of  principal  and interest by
Borrower under the Revolving Loan  Commitments on a Pro Rata basis.  Each Lender
shall perform all duties and  obligations of Lenders under this Agreement in the
same proportion as its ownership  interest in the Loans  outstanding at the date
of determination thereof.

     SECTION 15.14. INVESTMENTS. Whenever Agent in good faith determines that it
is uncertain about how to distribute to Lenders any funds which it has received,
or whenever Agent in good faith  determines  that there is any dispute among the
Lenders  about how such funds should be  distributed,  Agent may choose to defer
distribution of the funds which are the subject of such



                                       62


uncertainty or dispute.  If Agent in good faith believes that the uncertainty or
dispute  will not be promptly  resolved,  or if Agent is  otherwise  required to
invest funds pending  distribution  to the Lenders,  Agent may invest such funds
pending  distribution  (at the  risk of  Borrower).  All  interest  on any  such
investment  shall be distributed upon the distribution of such investment and in
the same  proportions  and to the same  Persons as such  investment.  All monies
received by Agent for  distribution to the Lenders (other than to the Person who
is  Agent in its  separate  capacity  as a  Lender)  shall be held by the  Agent
pending such distribution solely as Agent for such Lenders, and Agent shall have
no equitable title to any portion thereof.

                                  MISCELLANEOUS

     SECTION 16.1. NO WAIVER;  MODIFICATION  IN WRITING.  No failure or delay on
the part of the Agent  and/or the  Lenders  in  exercising  any right,  power or
remedy  hereunder  shall  operate as a waiver  thereof,  nor shall any single or
partial  exercise  of any such  right,  power or  remedy  preclude  any other or
further  exercise  thereof or the exercise of any other  right,  power or remedy
hereunder.  No  amendment,  modification  or  waiver  of any  provision  of this
Agreement  or of the  Notes,  nor  consent  to  any  departure  by the  Borrower
therefrom,  shall in any event be effective  unless the same shall be in writing
signed  by or on behalf of the  Agent  and the  Required  Lenders  and then such
waiver or consent shall be effective  only in the specific  instance and for the
specific  purpose for which given. No notice to or demand on the Borrower in any
case shall  entitle  the  Borrower  to any other or further  notice or demand in
similar or other  circumstances.  Notwithstanding  the  foregoing,  the  parties
acknowledge  that (i) the  Consent  Relating  to  Amended  and  Restated  Credit
Agreement  dated as of June 20,  2003 by and among  Borrower,  CCBM,  Inc.,  and
Hibernia,  and (ii) the  Consent  dated June ____,  2004 by and among  Borrower,

person  named below shall  notify the others in writing of another  address,  in
which case notices and communications shall be mailed, by certified mail, return

     SECTION 16.3. FEES AND EXPENSES.  The Borrower agrees to pay all reasonable
out of pocket  fees,  costs and  expenses  of the Agent in  connection  with the
preparation, execution and delivery of this Agreement, and all Related Documents

disbursements  of counsel to the Agent, and to pay all costs and expenses of the
Agent and the Lenders in connection with the enforcement of this Agreement,  the
Notes or the  other  Related  Documents,  including  reasonable  legal  fees and



                                       64


disbursements arising in connection therewith.  The Borrower also agrees to pay,
and to save the Agent and the Lenders  harmless  from any delay in paying  stamp
and other  similar  taxes,  if any,  which may be  payable or  determined  to be
payable in connection  with the execution  and delivery of this  Agreement,  the
Notes, the other Related Documents, or any modification thereof.

     SECTION  16.4.  SECURITY  INTEREST AND RIGHT OF SET-OFF.  The Lenders shall
have a  continuing  security  interest  in, as well as the right to set-off  the
obligations of the Borrower hereunder against,  all funds which the Borrower may
maintain on deposit  with any Lender (with the  exception of funds  deposited in
the Borrower's accounts in trust for third parties or funds deposited in pension
accounts,  IRA's,  Keogh accounts and All Saver  Certificates),  and the Lenders
shall have a lien upon and a security  interest in all  property of the Borrower
in a Lender's  possession or control which shall secure the  Indebtedness of the
Borrower to the Lenders under this Agreement and the Notes.

     SECTION 16.5.  WAIVER OF MARSHALING.  The Borrower and the Guarantor  shall
not at any  time  hereafter  assert  any  right  under  any  law  pertaining  to
marshaling  (whether  of assets or liens)  and the  Borrower  and the  Guarantor
expressly  agree that the Agent may execute or foreclose  upon the Collateral in
such order and manner as the Agent, in its sole discretion, deems appropriate.

     SECTION 16.6.  GOVERNING  LAW. This Agreement and the Notes shall be deemed
to be  contracts  made  under  the laws of the  State of  Louisiana  and for all
purposes shall be governed by and construed in accordance  with the laws of said
State.

     SECTION 16.7. CONSENT TO LOAN PARTICIPATION. The Borrower and the Guarantor
agree and consent to any Lender's sale or transfer, whether now or later, of one
or more  participation  interests in the  Indebtedness  of the Borrower  arising
pursuant  to  this  Agreement  to one or more  purchasers,  whether  related  or
unrelated to the Lender. Such Lender may provide, subject to the confidentiality
requirements  of Section  16.15,  to any one or more  purchasers,  or  potential
purchasers,  any  information  or  knowledge  such  Lender  may have  about  the
Borrower, the Guarantor or about any other matter relating to such Indebtedness.
The  Borrower  and the  Guarantor  also  agree that the  purchasers  of any such
participation  interest  will  be  considered  as the  absolute  owners  of such
interests  in such  Indebtedness.  In  addition,  any  sale  of a  participation
interest in the Indebtedness prior to the occurrence of an Event of Default will
require  the  Borrower's  consent,  which  consent  shall  not  be  unreasonably
withheld.

     SECTION  16.8.  CONSENT TO  SYNDICATION.  The  Borrower  and the  Guarantor
understand  and  acknowledge  that Agent may  syndicate the Loans to one or more
other lending institutions.  The Borrower and the Guarantor consent,  subject to

distribution to interested lending institutions of all financial information and
other  data  in  Agent's  possession  concerning  Borrower  and  the  Guarantor,
including  data  prepared  by or for  Borrower  and the  Guarantor,  so that the
interested lending institution(s) may evaluate the Loans and the Collateral. The
Agent will provide notice to the Borrower of the lending  institutions  that are
distributed  financial data concerning Borrower and the Guarantor.  The Borrower
and the  Guarantor  agree to enter  into an  amendment  or  restatement  of this
Agreement  and  any of  the  Related  Documents  in  order  to  facilitate  such
syndication;  provided,  however,  any syndication prior to the occurrence of an
Event of Default will require the



                                       65


Borrower's  consent,  which  consent  shall  not be  unreasonably  withheld.  In
addition,   the  Agent  is  expressly  authorized  to  seek  additional  lending
institutions to become a lender hereunder to fund any increase to the Facility A
Borrowing Base Amount and/or the Facility B Borrowing Base Amount.

     SECTION 16.9. PERMITTED ASSIGNMENTS. Any Lender may, in the ordinary course
of its business and in accordance with applicable law, at any time assign to one
or more banks or other entities ("Purchasers") all or any part of its rights and
obligations under the Loan Documents.  Such assignment shall be substantially in
the form of Exhibit C or in such  other form as may be agreed to by the  parties
thereto. The consent of the Borrower and the Agent shall be required prior to an
assignment  becoming effective with respect to a Purchaser which is not a Lender
or an affiliate thereof;  provided,  however, that if a Default has occurred and
is continuing,  the consent of the Borrower shall not be required.  Such consent
shall not be unreasonably withheld or delayed. Each such assignment with respect
to a Purchaser which is not a Lender or an affiliate  thereof shall (unless each
of the Borrower and the Agent otherwise  consents) be in an amount not less than
the lesser of (i)  $5,000,000.00  or (ii) the remaining  amount of the assigning
Lender's  Commitment   (calculated  as  at  the  date  of  such  assignment)  or
outstanding Loans (if the applicable  Commitment has been terminated).  Upon (i)
delivery to the Agent of an assignment,  together with any consents  required by
this Section,  and (ii) payment of a $3,500 fee to the Agent for processing such
assignment  (unless  such fee is waived by the  Agent),  such  assignment  shall
become  effective  on the  effective  date  specified  in such  assignment.  The
assignment  shall contain a  representation  by the Purchaser to the effect that
none of the consideration  used to make the purchase of the Commitment under the
applicable assignment agreement constitutes "plan assets" as defined under ERISA
and that the  rights  and  interests  of the  Purchaser  in and  under  the Loan
Documents will not be "plan assets" under ERISA. On and after the effective date
of such  assignment,  such Purchaser shall for all purposes be a Lender party to
this  Agreement  and any other  Loan  Document  executed  by or on behalf of the
Lenders and shall have all the rights and obligations of a Lender under the Loan
Documents,  to the same extent as if it were an original  party  hereto,  and no
further  consent or action by the  Borrower,  the  Lenders or the Agent shall be
required to release the transferor Lender with respect such assignment. Upon the
consummation  of any  assignment to a Purchaser  pursuant to this  Section,  the
transferor Lender, the Agent and the Borrower shall, if the transferor Lender or
the  Purchaser  desires that its Loans be evidenced by Notes,  make  appropriate
arrangements so that new Notes or, as appropriate,  replacement Notes are issued
to such transferor Lender and new Notes or, as appropriate,  replacement  Notes,
are issued to such Purchaser, in each case in principal amounts reflecting their
respective Commitments, as adjusted pursuant to such assignment.

     SECTION 16.10. INDEMNITY.

     (a)  Subject to the  limitations  set forth in  Section  12.6 as to matters
addressed  therein,  the Borrower and the Guarantor  agree to indemnify and hold
harmless  the Agent and the Lenders and their  respective  officers,  employees,
agents, attorneys and representatives  (singularly,  an "Indemnified Party", and
collectively,  the  "Indemnified  Parties")  from and  against  any loss,  cost,
liability,  damage or expense  (including the reasonable fees and  out-of-pocket
expenses of counsel to the Agent and/or the Lenders, including all local counsel
hired by such  counsel)  ("Claim")  incurred by the Agent  and/or the Lenders in
investigating  or preparing  for,  defending



                                       66


against, or providing  evidence,  producing documents or taking any other action
in respect of any commenced or threatened litigation,  administrative proceeding
or   investigation   under  any  federal   securities  law,   federal  or  state
environmental law, or any other statute of any jurisdiction,  or any regulation,
or at common law or otherwise, which is alleged to arise out of or is based upon
any acts,  practices  or omissions  or alleged  acts,  practices or omissions of
Borrower and the Guarantor,  or its or their agents or arises in connection with
the  duties,   obligations  or  performance  of  the   Indemnified   Parties  in
negotiating,    preparing,    executing,    accepting,    keeping,   completing,
countersigning,  issuing, selling, delivering,  releasing,  assigning, handling,
certifying,  processing  or receiving or taking any other action with respect to
the Loan Documents and all documents,  items and materials  contemplated thereby
even if any of the  foregoing  arises  out of an  Indemnified  Party's  ordinary
negligence.  The  indemnity  set forth  herein shall be in addition to any other
obligations or liabilities of Borrower and the Guarantor to the Agent and/or the
Lenders  hereunder  or at  common  law  or  otherwise,  and  shall  survive  any
termination  of this  Agreement,  the  expiration of the Facility  Loans and the
payment of all  indebtedness of Borrower to the Lenders  hereunder and under the
Notes,  provided that Borrower and the Guarantor shall have no obligation  under
this Section to the  Indemnified  Parties  with respect to any of the  foregoing
arising out of the gross  negligence or willful  misconduct  of the  Indemnified
Parties. If any Claim is asserted against any Indemnified Party, the Indemnified
Party shall  endeavor to notify  Borrower  and the  Guarantor of such Claim (but
failure to do so shall not affect the indemnification  herein made except to the
extent of the actual harm caused by such failure).  The Indemnified  Party shall
have the right to employ,  at  Borrower's  expense,  counsel of the  Indemnified
Parties'  choosing  and to control  the  defense of the Claim.  The  Borrower or
Guarantor  may at its/their own expense also  participate  in the defense of any
Claim. Each Indemnified Party may employ separate counsel in connection with any
Claim to the extent such  Indemnified  Party  believes it reasonably  prudent to
protect such  Indemnified  Party.  THE PARTIES INTEND FOR THE PROVISIONS OF THIS
SECTION TO APPLY TO AND PROTECT EACH INDEMNIFIED  PARTY FROM THE CONSEQUENCES OF
ANY LIABILITY  INCLUDING STRICT LIABILITY IMPOSED OR THREATENED TO BE IMPOSED ON
INDEMNIFIED  PARTY  AS WELL  AS FROM  THE  CONSEQUENCES  OF ITS OWN  NEGLIGENCE,
WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING, OR CONCURRING CAUSE OF
ANY CLAIM.

     (b) No Indemnified Party may settle any claim to be indemnified without the
consent  of  the  indemnitor,  such  consent  not to be  unreasonably  withheld;
provided,  that  the  indemnitor  may not  reasonably  withhold  consent  to any
settlement that an Indemnified  Party proposes,  if the indemnitor does not have
the  financial  ability  to pay all its  obligations  outstanding  and  asserted
against the indemnitor at that time, including,  without limitation, the maximum
potential  claims  pending  or to the  knowledge  of the  indemnitee  threatened
against the Indemnified Party to be indemnified pursuant to this Section 16.10.

     SECTION  16.11.  MAXIMUM  INTEREST  RATE.   Regardless  of  any  provisions
contained in this Agreement or in any other documents and  instruments  referred
to  herein,  the  Lenders  shall  never be deemed to have  contracted  for or be
entitled  to  receive,  collect or apply as  interest on the Notes any amount in
excess of the Maximum Rate, and in the event Lenders ever receives,  collects or
applies as interest any such excess,  of if an  acceleration  of the maturity of
the Notes or if any prepayment by Borrower  results in Borrower  having paid any
interest in excess of the Maximum  Rate,  such amount  which would be  excessive
interest  shall be applied to the reduction of the unpaid  principal  balance of
the Notes for which such excess was received,  collected or



                                       67


applied,  and,  if the  principal  balance  of the Notes  are paid in full,  any
remaining excess shall forthwith be paid to Borrower. All sums paid or agreed to
be paid to the Lenders for the use, forbearance or detention of the indebtedness
evidenced by the Notes and/or this Agreement  shall, to the extent  permitted by
applicable law, be amortized, prorated, allocated and spread throughout the full
term of such  indebtedness  until  payment in full so that the rate or amount of
interest on account of such  indebtedness  does not exceed the Maximum  Rate. In
determining  whether  or not the  interest  paid or payable  under any  specific
contingency  exceeds the Maximum Rate of interest permitted by law, Borrower and
the Lenders shall,  to the maximum extent  permitted  under  applicable law, (i)
characterize any  non-principal  payment as an expense,  fee or premium,  rather
than as interest; and (ii) exclude voluntary prepayments and the effect thereof;
and (iii)  compare  the total  amount of  interest  contracted  for,  charged or
received  with the total  amount of  interest  which  could be  contracted  for,
charged or received  throughout the entire contemplated term of the Notes at the
Maximum Rate.

     SECTION 16.12. WAIVER OF JURY TRIAL; SUBMISSION TO JURISDICTION.

     (a) THE BORROWER,  THE  GUARANTOR,  THE AGENT AND THE LENDERS  HEREBY WAIVE
TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO WHICH THE BORROWER,  THE GUARANTOR,
THE  AGENT  AND  THE  LENDERS  MAY BE  PARTIES,  ARISING  OUT  OF OR IN ANY  WAY
PERTAINING TO (i) THE NOTES, (ii) THIS AGREEMENT, (iii) THE COLLATERAL DOCUMENTS
OR (iv) THE COLLATERAL. IT IS AGREED AND UNDERSTOOD THAT THIS WAIVER CONSTITUTES
A WAIVER OF TRIAL BY JURY OF ALL CLAIMS  AGAINST ALL PARTIES TO SUCH  ACTIONS OR
PROCEEDINGS,  INCLUDING  CLAIMS  AGAINST  PARTIES  WHO ARE NOT  PARTIES  TO THIS
AGREEMENT.  THIS WAIVER IS  KNOWINGLY,  WILLINGLY  AND  VOLUNTARILY  MADE BY THE
BORROWER, THE GUARANTOR, THE AGENT AND THE LENDERS, AND THE BORROWER, THE AGENT,
AND THE LENDERS HEREBY REPRESENT THAT NO REPRESENTATIONS OF FACT OR OPINION HAVE
BEEN MADE BY ANY  INDIVIDUAL TO INDUCE THIS WAIVER OF TRIAL BY JURY OR TO IN ANY
WAY MODIFY OR NULLIFY ITS EFFECT. THE BORROWER, THE GUARANTOR, THE AGENT AND THE
LENDERS EACH FURTHER  REPRESENT  THAT IT HAS BEEN  REPRESENTED IN THE SIGNING OF
THIS  AGREEMENT AND IN THE MAKING OF THIS WAIVER BY  INDEPENDENT  LEGAL COUNSEL,
SELECTED OF ITS OWN FREE WILL,  AND THAT IT HAS HAD THE  OPPORTUNITY  TO DISCUSS
THIS WAIVER WITH COUNSEL.

     (b) THE  BORROWER  AND THE  GUARANTOR  HEREBY  IRREVOCABLY  CONSENT  TO THE
JURISDICTION  OF THE  STATE  COURTS  OF  LOUISIANA  AND THE  FEDERAL  COURTS  IN
LOUISIANA AND AGREES THAT ANY ACTION OR PROCEEDING  ARISING OUT OF OR BROUGHT TO
ENFORCE  THE  PROVISIONS  OF THE  REVOLVING  NOTE,  THIS  AGREEMENT  AND/OR  THE
COLLATERAL  DOCUMENTS  MAY  BE  BROUGHT  IN  ANY  COURT  HAVING  SUBJECT  MATTER
JURISDICTION.

     SECTION 16.13. SEVERABILITY. If a court of competent jurisdiction finds any
