                   SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

     2.1 Term Loans.  Subject to the terms and conditions hereof, each Term Loan
Lender  severally  agrees to make a term loan (a "Term Loan") to the Borrower on
the  Closing  Date in an  amount  not to  exceed  the  amount  of the Term  Loan
Commitment  of  such  Lender.  The  Term  Loans  may  from  time  to time be (a)
Eurodollar  Loans,  (b)  Base  Rate  Loans  or  (c)  a combination  thereof,  as
determined  by  the  Borrower  and  notified  to  the  Administrative  Agent  in
accordance with Sections 2.2 and 2.10.

     2.2  Procedure  for  Term  Loan  Borrowing.  The  Borrower  shall  give the
Administrative  Agent  irrevocable  notice (which notice must be received by the
Administrative  Agent prior to 10:00 A.M.,  New York City time, one Business Day
prior to the  anticipated  Closing Date)  requesting  that the Term Loan Lenders
make Term Loans on the Closing Date and specifying (a) the amount to be borrowed
and (b) the Closing Date. Upon receipt of such notice, the Administrative  Agent
shall promptly notify each Term Loan Lender thereof.  Not later than 12:00 Noon,
New York City  time,  on the  Closing  Date,  each Term Loan  Lender  shall make
available to the Administrative Agent at its office specified in Section 10.2 an
amount in immediately  available funds equal to the Term Loan to be made by such
Lender. The Administrative  Agent shall on such date by 2:00 P.M., New York City
time, make available to the Borrower, in accordance with the instructions of the
Borrower,  in like  funds as  received  by the  Administrative  Agent,  all such
amounts made available to the Administrative Agent by the Term Loan Lenders.

     2.3 Revolving Credit  Commitments.  (a) Subject to the terms and conditions
hereof,  each Revolving  Credit Lender severally agrees to make revolving credit
loans  ("Revolving  Credit  Loans") to the Borrower from time to time during the
Revolving Credit Commitment  Period in an aggregate  principal amount at any one
time outstanding  which, when added to such Lender's Revolving Credit Percentage
of the L/C  Obligations  then  outstanding,  does not  exceed the amount of such
Lender's  Revolving Credit  Commitment.  During the Revolving Credit  Commitment
Period,  the Borrower may use the  Revolving  Credit  Commitments  by borrowing,
prepaying the Revolving Credit Loans in whole or in part, and  reborrowing,  all
in accordance with the terms and conditions hereof.

     (b) The  Revolving  Credit  Loans may from  time to time be (i)  Eurodollar
Loans, (ii) Base Rate Loans or (iii) a combination thereof, as determined by the
Borrower and notified to the  Administrative  Agent in accordance  with Sections
2.4 and  2.10,  provided  that  no  Revolving  Credit  Loan  shall  be made as a
Eurodollar  Loan after the day that is one month prior to the  Revolving  Credit
Termination  Date. (c) The Revolving  Credit  Commitments  shall be reduced (and
each Revolving  Credit Lender's  Revolving  Credit  Commitment  shall be ratably
reduced) on each anniversary of the Closing Date, commencing with the third such
anniversary, to the amount set forth opposite such anniversary below:

                           Anniversary                  Amount

                           Third                     $110,000,000
                           Fourth                    $ 80,000,000
                           Fifth                     $          0

     2.4 Procedure for Revolving Credit Borrowing. The Borrower may borrow under
the Revolving Credit  Commitments  during the Revolving Credit Commitment Period
on any Business Day,  provided that the Borrower  shall give the  Administrative
Agent  irrevocable  notice (which notice must be received by the  Administrative
Agent prior to 12:00 Noon,  New York City time, (a) three Business Days prior to
the requested  Borrowing  Date,  if all or any part of the  requested  Revolving
Credit  Loans are to be  Eurodollar  Loans or (b) one  Business Day prior to the
requested Borrowing Date, otherwise),  specifying (i) the amount to be borrowed,
(ii) the  requested  Borrowing  Date,  (iii)  whether the  borrowing is to be of
Eurodollar  Loans,  Base Rate Loans,  or a  combination  thereof and (iv) if the
borrowing  is to be  entirely  or partly of  Eurodollar  Loans,  the  respective
amounts  of each such Type of Loan and the  respective  lengths  of the  initial
Interest Periods therefor. Each borrowing under the Revolving Credit Commitments
shall be in an amount equal to (x) in the case of Base Rate Loans, $1,000,000 or
a whole multiple thereof (or, if the then Available Revolving Credit Commitments
are less than $1,000,000,  such lesser amount) and (y) in the case of Eurodollar
Loans,  $5,000,000 or a whole  multiple of $1,000,000  in excess  thereof.  Upon
receipt of any such notice from the  Borrower,  the  Administrative  Agent shall
promptly  notify each Revolving  Credit Lender  thereof.  Each Revolving  Credit
Lender will make the amount of its pro rata share of each borrowing available to
the  Administrative  Agent for the account of the  Borrower at the office of the
Administrative  Agent  specified in Section  10.2 prior to 11:00 A.M.,  New York
City time, on the Borrowing Date requested by the Borrower in funds  immediately
available  to the  Administrative  Agent.  The  aggregate  of the  amounts  made
available to the Administrative  Agent by the Revolving Credit Lenders will then
be made available to the Borrower by the Administrative Agent in accordance with
the instructions of the Borrower in like funds as received by the Administrative
Agent.

     2.5  Commitment   Fees,  etc.  (a)  The  Borrower  agrees  to  pay  to  the
Administrative  Agent  for  the  account  of  each  Revolving  Credit  Lender  a
commitment  fee for the period from and  including  the Closing Date to the last
day of the Revolving Credit  Commitment  Period,  computed at the rate per annum
set forth  under the  heading  "Commitment  Fee Rate" on Annex I on the  average
daily amount of the Available  Revolving Credit Commitment of such Lender during
the period for which payment is made,  payable  quarterly in arrears on the last
day of each  March,  June,  September  and  December  and on the last day of the
Revolving  Credit  Commitment  Period,  commencing on the first of such dates to
occur after the date hereof.

     (b)  The  Borrower  agrees  to pay to  the  Arranger  the  fees  and  other
compensation in the amounts and on the dates previously  agreed to in writing by
the Borrower and the Arranger.

     (c) The Borrower agrees to pay to the Administrative  Agent the fees in the
amounts and on the dates  agreed to in writing from time to time by the Borrower
and the Administrative Agent.

     (d) The  Borrower  agrees  to pay to the  Collateral  Agent the fees in the
amount and on the dates  agreed to in writing  from time to time by the Borrower
and the Collateral Agent.

     2.6  Repayment  of  Loans;  Evidence  of  Debt.  (a)  The  Borrower  hereby
unconditionally  promises to pay to the Administrative  Agent for the account of
the appropriate  Lender (i) the then unpaid  principal  amount of each Revolving
Credit Loan of such  Revolving  Credit  Lender on the last day of the  Revolving
Credit  Commitment  Period (or such earlier date on which the  Revolving  Credit
Loans  become due and  payable  pursuant  to  Section 8) and (ii) the  principal
amount of the Term Loans of such Term Loan Lender,  in 25 consecutive  quarterly
installments,  each of which installments for each Lender shall be such Lender's
Term Loan Percentage of the amount for such  installment  payment date set forth
on the amortization  schedule set forth on Schedule 2.6,  commencing on June 30,
1998 and on the last day of each March, June,  September and December thereafter
(or on such earlier date on which the then unpaid  principal  amount of the Term
Loans become due and payable pursuant to Section 8). The Borrower hereby further
agrees to pay interest on the unpaid  principal amount of the Loans from time to
time outstanding from the date hereof until payment in full thereof at the rates
per annum, and on the dates, set forth in Section 2.12.

     (b) Each Lender shall  maintain in  accordance  with its usual  practice an
account or  accounts  evidencing  indebtedness  of the  Borrower  to such Lender
resulting from each Loan of such Lender from time to time, including the amounts
of  principal  and  interest  payable  and paid to such Lender from time to time
under this Agreement.

     (c) The Administrative Agent, on behalf of the Borrower, shall maintain the
Register  pursuant to Section 10.6(e) and a subaccount  therein for each Lender,
in which shall be recorded (i) the amount of each Revolving Credit Loan and Term
Loan made  hereunder,  the Type  thereof  and each  Interest  Period  applicable
thereto,  (ii) the amount of any  principal  or  interest  due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iii) both
the amount of any sum received by the  Administrative  Agent  hereunder from the
Borrower and each Lender's share thereof.

     (d) The  entries  made in the  Register  and the  accounts  of each  Lender
maintained  pursuant  to  Section  2.6(b)  shall,  to the  extent  permitted  by
applicable  law, be prima facie  evidence  of the  existence  and amounts of the
obligations  of the  Borrower  therein  recorded;  provided,  however,  that the
failure of any Lender or the  Administrative  Agent to maintain  the Register or
any such  account,  or any error  therein,  shall not in any  manner  affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
such Borrower by such Lender in accordance with the terms of this Agreement. (e)
The Borrower  agrees that, upon the request to the  Administrative  Agent by any
Lender,  the  Borrower  will execute and deliver to such Lender (i) a promissory
note of the  Borrower  evidencing  any  Revolving  Credit  Loans of such Lender,
substantially in the form of Exhibit C-1 with appropriate  insertions as to date
and principal amount (a "Revolving Credit Note"),  and/or (ii) a promissory note
of the Borrower  evidencing any Term Loan of such Lender,  substantially  in the
form of Exhibit C-2 with appropriate  insertions as to date and principal amount
(a "Term Note"). A Note and the obligation  evidenced thereby may be assigned or
otherwise  transferred  in  whole  or in  part  only  by  registration  of  such
assignment or transfer of such Note and the obligation  evidenced thereby in the
Register (and each Note shall expressly so provide).  Any assignment or transfer
of all or part of an  obligation  evidenced by a Note shall be registered in the
Register only upon surrender for  registration  of assignment or transfer of the
Note  evidencing  such  obligation,  accompanied by an Assignment and Acceptance
substantially  in the form of Exhibit G duly  executed by the Assignor  thereof,
and thereupon one or more new Notes shall be issued to the  designated  Assignee
and the old Note shall be returned by the  Administrative  Agent to the Borrower
marked "cancelled". No assignment of a Note and the obligation evidenced thereby
shall be  effective  unless it shall have been  recorded in the  Register by the
Administrative Agent as provided in this Section 2.6(e).

     2.7 Optional Termination or Reduction of Revolving Credit Commitments.  The
Borrower shall have the right, upon not less than three Business Days' notice to
the Administrative Agent, to terminate the Revolving Credit Commitments or, from
time to time, to reduce the amount of the Revolving Credit Commitments; provided
that no such termination or reduction of Revolving Credit  Commitments  shall be
permitted  if,  after  giving  effect  thereto  and  to any  prepayments  of the
Revolving  Credit  Loans  made on the  effective  date  thereof,  the sum of the
Aggregate  Outstanding  Revolving  Extensions of Credit of all Revolving  Credit
Lenders would exceed the Revolving Credit  Commitments then in effect.  Any such
reduction  shall  be in an  amount  equal  to  $1,000,000,  or a whole  multiple
thereof,  and shall reduce  permanently the Revolving Credit Commitments then in
effect.

     2.8  Optional  Prepayments.  The  Borrower may at any time and from time to
time prepay the Loans, in whole or in part, without premium or penalty,  upon at
least three Business Days' irrevocable notice to the Administrative Agent by the
Borrower,  specifying  the  date  and  amount  of  prepayment  and  whether  the
prepayment is of  Eurodollar  Loans,  Base Rate Loans or a combination  thereof,
and, if of a combination thereof, the amount allocable to each, provided that if
a Eurodollar  Loan is prepaid on any day other than the last day of the Interest
Period applicable thereto the Borrower shall also pay any amounts owing pursuant
to Section 2.19. Upon receipt of any such notice, the Administrative Agent shall
promptly  notify each Lender  thereof.  If any such notice is given,  the amount
specified in such notice shall be due and payable on the date specified therein,
together  with  accrued  interest  to such date on the amount  prepaid.  Partial
prepayments of the Term Loans shall be applied to the remaining  installments in
the direct order of the  scheduled  payment date  thereof.  Notwithstanding  the
foregoing, so long as any Revolving Credit Loans are outstanding, each Term Loan
Lender  shall  have the right to refuse  all or any  portion  of any  prepayment
pursuant to this Section 2.8  allocable  to such  Lender's  Term Loans,  and the
amount so refused shall be applied to prepay the Revolving Credit Loans. Amounts
prepaid on account of the Term Loans may not be reborrowed.  Partial prepayments
of Term Loans and  Revolving  Credit  Loans shall be in an  aggregate  principal
amount of $1,000,000 or a whole multiple thereof.

     2.9 Mandatory Prepayments and Commitment  Reductions.  (a) If any senior or
subordinated  debt  securities  or  instruments  of the  Borrower  or any of its
Subsidiaries shall be issued or sold, or the Borrower or any of its Subsidiaries
shall incur any Indebtedness, after the Closing Date (except any debt securities
or instruments issued or sold or Indebtedness incurred pursuant to Section 7.2),
an amount equal to 100% of the Net Cash Proceeds thereof shall be applied on the
date of such issuance, sale or incurrence toward the prepayment of the Revolving
Credit Loans and, with respect to Net Cash Proceeds  thereof  received after the
third  anniversary of the Closing Date only, the prepayment of the Loans and the
reduction of the Revolving  Credit  Commitments as set forth in paragraph (f) of
this Section 2.9.  Nothing in this  paragraph  (a) shall be deemed to permit the
incurrence of Indebtedness not permitted by Section 7.2.

     (b) If any Capital Stock of the Borrower or any of its  Subsidiaries  shall
be issued or sold after the Closing Date  (except any Capital  Stock issued as a
part of the consideration of and in connection with a Permitted Acquisition), an
amount equal to 100% of the Net Cash  Proceeds  thereof  shall be applied on the
date of such  issuance or sale toward the  prepayment  of the  Revolving  Credit
Loans and, with respect to Net Cash Proceeds  thereof  received  after the third
anniversary  of the  Closing  Date  only,  the  prepayment  of the Loans and the
reduction of the Revolving  Credit  Commitments as set forth in paragraph (f) of
this Section 2.9; provided that, so long as no Default or Event of Default shall
have occurred and be  continuing,  the Borrower  shall not be required to reduce
the Revolving  Credit  Commitments  to less than  $80,000,000 as a result of the
application of Net Cash Proceeds pursuant to this paragraph (b).

     (c) If the  Borrower  or any of its  Subsidiaries  shall  receive  Net Cash
Proceeds from any Asset Sale or Recovery  Event after the Closing Date,  100% of
the Net Cash  Proceeds  thereof  shall  be  applied  on the  date  such Net Cash
Proceeds are received  toward the  prepayment  of the Loans and the reduction of
the Revolving  Credit  Commitments as set forth in paragraph (f) of this Section
2.9.  Notwithstanding the foregoing sentence, (i) no prepayment and reduction of
Revolving  Credit  Commitments  shall  be  required  in  respect  of  the  first
$2,000,000 in Net Cash Proceeds received from Asset Sales and Recovery Events in
any fiscal year  (excluding  any Net Cash  Proceeds  described in clause (ii) of
this  sentence)  and (ii) if no Default or Event of Default  shall have occurred
and be continuing and a  Reinvestment  Notice with respect to such Asset Sale or
Recovery Event has been delivered, to the extent that the Net Cash Proceeds from
any Asset Sale or Recovery Event are to be used to restore or replace the assets
in respect  of which an Asset Sale or  Recovery  Event has  occurred  within six
months from the date of such Asset Sale or Recovery  Event,  as  certified  by a
Responsible  Officer of the Borrower pursuant to such Reinvestment  Notice, such
Net Cash Proceeds  shall not be applied  toward the  prepayment of Loans and the
reduction of the Revolving Credit Commitments except as provided in the next two
succeeding  sentences.  If the Net Cash  Proceeds  from any  Reinvestment  Event
exceed  $5,000,000,  the Borrower shall deposit such Net Cash Proceeds in a cash
collateral   account   under  the   exclusive   dominion   and  control  of  the
Administrative  Agent as security for the  Obligations in accordance  with terms
and conditions  reasonably  satisfactory to the Administrative Agent pending the
reinvestment of such Net Cash Proceeds. On each Reinvestment Prepayment Date, an
amount  equal  to  the  Reinvestment  Prepayment  Amount  with  respect  to  the
applicable  Reinvestment  Event shall be applied  toward the  prepayment  of the
Loans and the  reduction of the  Revolving  Credit  Commitments  as set forth in
paragraph (f) of this Section 2.9.

     (d) If, for any  fiscal  year of the  Borrower  ending on or after June 30,
2000,  there shall be Excess Cash Flow,  the  Borrower  shall,  on the  relevant
Excess Cash Flow Application  Date, apply toward the prepayment of the Loans and
the reduction of the Revolving Credit  Commitments as set forth in paragraph (f)
of this  Section 2.9 an amount  equal to (i) 50% of such Excess Cash Flow if the
Consolidated  Leverage  Ratio at the end of the  relevant  fiscal  year shall be
greater  than or equal to 3.00 to 1.00 or (ii) 25% of such  Excess  Cash Flow if
the Consolidated  Leverage Ratio at the end of the relevant fiscal year shall be
less than 3.00 to 1.00. Each such  prepayment and commitment  reduction shall be
made on a date (an  "Excess  Cash Flow  Application  Date")  no later  than five
Business  Days  after  the  earlier  of (i) the  date  on  which  the  financial
statements  of the  Borrower  referred to in Section  6.1(a) for the fiscal year
with  respect to which such  prepayment  is made are required to be delivered to
the Lenders and (ii) the date such financial statements are actually delivered.

     (e) If any Convertible Subordinated Debentures are outstanding on April 30,
2003,  the Borrower  shall prepay the Term Loans in full on such date,  together
with all accrued  interest  thereon and all amounts payable  pursuant to Section
2.19 in connection with such prepayment.

     (f)  Amounts to be  applied in  connection  with  prepayments  of Loans and
Revolving Credit  Commitment  reductions made pursuant to this Section 2.9 shall
be applied,  first, to prepay the Revolving Credit Loans and reduce  permanently
the Revolving Credit Commitments,  pro rata according to the outstanding amounts
of Revolving Credit  Commitments,  except for amounts to be applied prior to the
third anniversary of the Closing Date pursuant to paragraphs (a) and (b) of this
Section  2.9  which  shall  be  applied  only  toward  prepayment  of  the  then
outstanding  Revolving Credit Loans and not to reduce  permanently the Revolving
Credit  Commitments,  and,  second,  after the Aggregate  Outstanding  Revolving
Extensions of Credit and the Revolving  Credit  Commitments have been reduced to
zero, to prepay the Term Loans pro rata according to the  outstanding  principal
amounts thereof. Any such reduction of the Revolving Credit Commitments shall be
accompanied by prepayment of the Revolving  Credit Loans to the extent,  if any,
that the sum of the Aggregate  Outstanding Revolving Extensions of Credit of all
Revolving  Credit Lenders exceeds the amount of the aggregate  Revolving  Credit
Commitments as so reduced,  provided that if the aggregate  principal  amount of
Revolving  Credit Loans then  outstanding is less than the amount of such excess
(because L/C Obligations  constitute a portion thereof),  the Borrower shall, to
the extent of the balance of such excess,  replace outstanding Letters of Credit
and/or deposit an amount in cash in a cash collateral  account  established with
the Administrative  Agent for the benefit of the Lenders on terms and conditions
satisfactory  to the  Administrative  Agent.  Amounts  on  deposit  in the  cash
collateral  account shall be invested as directed by the Borrower subject to the
approval of the  Administrative  Agent, which approval shall not be unreasonably
withheld.  The application of any prepayment  pursuant to this Section 2.9 shall
be made first to Base Rate Loans and second to Eurodollar  Loans,  provided that
at the  request  of the  Borrower  the  application  of  any  prepayment  to any
Eurodollar  Loan may be delayed until the end of an Interest Period (or Interest
Periods)  so that such  application  does not  result in the  incurrence  by any
Lender of any loss or expense  under Section  2.19,  and during such delay,  the
Administrative  Agent  shall  hold  the  amount  of  such  prepayment  in a cash
collateral  account.  Amounts  prepaid in  respect  of the Term  Loans  shall be
applied to installments thereof pro rata according to the outstanding  principal
amounts  thereof.  Amounts  prepaid  on  account  of the Term  Loans  may not be
reborrowed.  Each  prepayment  of the  Loans  under  this  Section  2.9 shall be
accompanied  by accrued  interest to the date of such  prepayment  on the amount
prepaid.

     2.10 Conversion and Continuation  Options.  (a) The Borrower may elect from
time to time to  convert  Eurodollar  Loans to Base  Rate  Loans by  giving  the
Administrative  Agent at least two Business  Days' prior  irrevocable  notice of
such election, provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest  Period with respect  thereto.  The Borrower
may elect from time to time to convert  Base Rate Loans to  Eurodollar  Loans by
giving the Administrative  Agent at least three Business Days' prior irrevocable
notice of such election. Any such notice of conversion to Eurodollar Loans shall
specify the length of the initial Interest Period therefor.  Upon receipt of any
such notice, the Administrative Agent shall promptly notify each Lender thereof.
All or any part of  outstanding  Eurodollar  Loans  and Base  Rate  Loans may be
converted as provided herein,  provided that (i) no Loan may be converted into a
Eurodollar Loan (A) when any Event of Default has occurred and is continuing and
the  Administrative  Agent has or the Required Lenders have determined in its or
their sole  discretion not to permit such a conversion or (B) having an Interest
Period  in  excess of one  month  prior to the date  which is 60 days  after the
Closing Date and (ii) no Loan may be converted into a Eurodollar  Loan after the
date that is one month prior to (y) the Revolving Credit  Termination Date, with
respect to Revolving  Credit  Loans and (z) the Term Loan  Maturity  Date,  with
respect to Term Loans.

     (b) Any  Eurodollar  Loans may be continued as such upon the  expiration of
the then current  Interest  Period with respect  thereto by the Borrower  giving
irrevocable  notice  to  the  Administrative   Agent,  in  accordance  with  the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Loans,  provided
that no  Eurodollar  Loan may be continued as such (i) when any Event of Default
has occurred and is continuing and the Administrative  Agent has or the Required
Lenders have  determined  in its or their sole  discretion  not to permit such a
continuation or (ii) after the date that is one month prior to (A) the Revolving
Credit  Termination  Date, with respect to the Revolving Credit Loans or (B) the
Term Loan Maturity Date, with respect to Term Loans, and provided, further, that
if the  Borrower  shall fail to give any required  notice as described  above in
this  paragraph  or if  such  continuation  is  not  permitted  pursuant  to the
preceding proviso such Loans shall be automatically converted to Base Rate Loans
on the last day of such then expiring Interest Period.

     2.11  Minimum   Amounts  and  Maximum   Number  of   Eurodollar   Tranches.
Notwithstanding  anything to the  contrary in this  Agreement,  all  borrowings,
conversions,  continuations and optional  prepayments of Loans hereunder and all
selections of Interest  Periods  hereunder  shall be in such amounts and be made
pursuant  to such  elections  so that,  (a) after  giving  effect  thereto,  the
aggregate principal amount of the Loans comprising each Eurodollar Tranche shall
be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof,  (b)
no more than eight Eurodollar  Tranches in respect of the Revolving Credit Loans
shall be  outstanding  at any one time and (c) no more  than  twelve  Eurodollar
Tranches in respect of all Loans (including the Revolving Credit Loans) shall be
outstanding at any one time.

     2.12 Interest Rates and Payment Dates.  (a) Each Eurodollar Loan shall bear
interest for each day during each Interest Period with respect thereto at a rate
per  annum  equal  to the  Eurodollar  Rate  determined  for  such  day plus the
Applicable Margin.

     (b) Each Base Rate Loan shall bear  interest  at a rate per annum  equal to
the Base Rate plus the Applicable Margin.

     (c) If all or a  portion  of any  principal  of any  Loan or  Reimbursement
Obligations  shall not be paid when due  (whether  at the  stated  maturity,  by
acceleration  or  otherwise),  such amounts  shall bear interest at 2% above the
rate otherwise  applicable  thereto from the date of such non-payment until such
overdue principal is paid in full (as well after as before judgment).  If all or
a portion  of any  interest  shall not be paid when due  (whether  at the stated
maturity, by acceleration or otherwise),  such amounts shall bear interest at 2%
above the rate otherwise applicable to the Loans or Reimbursement Obligations on
which such interest accrued from the date of such non-payment until such overdue
principal  is paid in full  (as  well  after as  before  judgment).  If all or a
portion of any commitment fee or any other amount payable hereunder shall not be
paid when due (whether at the stated  maturity,  by  acceleration or otherwise),
such amounts shall bear interest at a rate which is 2% above the rate applicable
to Base Rate Loans which are Revolving  Credit Loans, in each case from the date
of such non-payment until such overdue commitment fee or other amount is paid in
full (as well after as before judgment).

     (d) Interest  shall be payable in arrears on each  Interest  Payment  Date,
provided that interest  accruing  pursuant to paragraph (c) of this Section 2.12
shall be payable from time to time on demand.

     2.13   Computation  of  Interest  and  Fees.  (a)  Interest  on  Loans  and
Reimbursement  Obligations,  commitment fees,  letter of credit  commissions and
interest  on  overdue  interest,  commitment  fees  and  other  amounts  payable
hereunder shall be calculated on the basis of a 360-day year for the actual days
elapsed,  except  that,  with respect to Base Rate Loans the rate of interest on
which is calculated on the basis of the Prime Rate,  the interest  thereon shall
be  calculated on the basis of a 365- (or 366-, as the case may be) day year for
the actual days elapsed.  The Administrative  Agent shall as soon as practicable
notify the Borrower and the Lenders of each  determination of a Eurodollar Rate.
Any change in the interest  rate on a Loan  resulting  from a change in the Base
Rate or the Eurocurrency  Reserve  Requirements shall become effective as of the
opening of  business  on the day on which such  change  becomes  effective.  The
Administrative  Agent shall as soon as  practicable  notify the Borrower and the
Lenders of the  effective  date and the amount of each such  change in  interest
rate.

     (b) Each  determination  of an interest  rate by the  Administrative  Agent
pursuant to any provision of this  Agreement  shall be conclusive and binding on
the Borrower and the Lenders in the absence of manifest error.

     2.14 Inability to Determine Interest Rate. If prior to the first day of any
Interest Period:

     (a) the  Administrative  Agent shall have determined  (which  determination
shall  be  conclusive  and  binding  upon  the  Borrower)  that,  by  reason  of
circumstances  affecting the relevant  market,  adequate and reasonable means do
not exist for ascertaining the Eurodollar Rate for such Interest Period, or

     (b) the  Administrative  Agent shall have received notice from the Required
Lenders  that  the  Eurodollar  Rate  determined  or to be  determined  for such
Interest  Period will not adequately and fairly reflect the cost to such Lenders
(as  conclusively  certified  by such  Lenders) of making or  maintaining  their
affected Loans during such Interest Period,

     the  Administrative  Agent shall give telecopy or telephonic notice thereof
to the  Borrower  and the  Lenders as soon as  practicable  thereafter.  If such
notice is given (x) any Eurodollar  Loans  requested to be made on the first day
of such  Interest  Period shall be made as Base Rate Loans,  (y) any  Loans that
were to  have  been  converted  on the  first  day of such  Interest  Period  to
Eurodollar  Loans shall be continued as Base Rate Loans and (z) any  outstanding
Eurodollar  Loans that were to be  continued  on the first day of such  Interest
Period as Eurodollar Loans shall be converted, on the first day of such Interest
Period,  to Base  Rate  Loans.  Until  such  notice  has been  withdrawn  by the
Administrative  Agent, no further Eurodollar Loans shall be made or continued as
such,  nor shall the  Borrower  have the right to  convert  Loans to  Eurodollar
Loans.

     2.15 Pro Rata  Treatment and Payments.  (a) Each  borrowing by the Borrower
from the  Lenders  hereunder,  each  payment by the  Borrower  on account of any
commitment fee and any reduction of the Commitments of the Lenders shall be made
pro rata according to the respective Term Loan  Percentages or Revolving  Credit
Percentages,  as the case may be, of the relevant Lenders. Except as provided in
Section 2.8, each payment (including each prepayment) by the Borrower on account
of principal of and interest on the Term Loans shall be made pro rata  according
to the respective  outstanding  principal amounts of the Term Loans then held by
the Term Loan Lenders.  Each payment (including each prepayment) by the Borrower
on account of principal of and interest on the  Revolving  Credit Loans shall be
made pro rata according to the respective  outstanding  principal amounts of the
Revolving Credit Loans then held by the Revolving  Credit Lenders.  Each payment
made at any time when any amount  hereunder is due and payable shall be made pro
rata  according to the  respective  amounts then due and payable to the Lenders.
All payments  (including  prepayments) to be made by the Borrower  hereunder and
under the Notes, whether on account of principal,  interest,  fees or otherwise,
shall be made without  setoff or  counterclaim  and shall be made prior to 12:00
Noon, New York City time, on the due date thereof to the  Administrative  Agent,
for the account of the Lenders,  at the Administrative  Agent's office specified
in Section  10.2,  in  Dollars  and in  immediately  available  funds.  Payments
received  by the  Administrative  Agent  after such time shall be deemed to have
been  received  on  the  next  Business  Day.  The  Administrative  Agent  shall
distribute  such payments to the Lenders  promptly upon receipt in like funds as
received. If any payment hereunder (other than payments on the Eurodollar Loans)
becomes due and payable on a day other than a Business  Day,  such payment shall
be extended to the next succeeding  Business Day. If any payment on a Eurodollar
Loan  becomes due and payable on a day other than a Business  Day,  the maturity
thereof shall be extended to the next succeeding  Business Day unless the result
of such extension  would be to extend such payment into another  calendar month,
in which event such payment shall be made on the immediately  preceding Business
Day. In the case of any  extension of any payment of  principal  pursuant to the
preceding  two  sentences,  interest  thereon  shall  be  payable  at  the  then
applicable rate during such extension.

     (b) Unless the Administrative  Agent shall have been notified in writing by
any Lender  prior to a borrowing  that such Lender will not make the amount that
would  constitute  its share of such borrowing  available to the  Administrative
Agent,  the  Administrative  Agent may assume  that such  Lender is making  such
amount available to the Administrative  Agent, and the Administrative Agent may,
in reliance upon such assumption, make available to the Borrower a corresponding
amount. If such amount is not made available to the Administrative  Agent by the
required  time on the  Borrowing  Date  therefor,  such Lender  shall pay to the
Administrative  Agent,  on demand,  such amount with interest  thereon at a rate
equal to the daily  average  Federal Funds  Effective  Rate for the period until
such Lender makes such amount immediately available to the Administrative Agent.
A certificate of the  Administrative  Agent submitted to any Lender with respect
to any amounts  owing under this  Section  2.15(b)  shall be  conclusive  in the
absence of manifest  error. If such Lender's share of such borrowing is not made
available to the Administrative  Agent by such Lender within three Business Days
of such  Borrowing  Date,  the  Administrative  Agent  shall also be entitled to
recover such amount with  interest  thereon at the rate per annum  applicable to
Base Rate Loans  hereunder,  on demand,  from the  Borrower  (together  with any
amounts due under  Section 2.19,  calculated as if such Lender's failure to fund
such amount were a failure of the  Borrower to borrow such amount  after  having
given  notice of such  borrowing).  Nothing  herein shall be deemed to limit the
rights of the Borrower against any defaulting Lender.

     (c) Unless the Administrative  Agent shall have been notified in writing by
the  Borrower  prior to the date of any payment  being made  hereunder  that the
Borrower  will  not  make  such  payment  to  the   Administrative   Agent,  the
Administrative  Agent may assume that the Borrower is making such  payment,  and
the  Administrative  Agent may, but shall not be required  to, in reliance  upon
such assumption,  make available to the Lenders their respective pro rata shares
of a  corresponding  amount.  If such payment is not made to the  Administrative
Agent by the Borrower  within three  Business  Days of such required  date,  the
Administrative  Agent shall be entitled to recover,  on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such  amount  with  interest  thereon  at the rate per annum  equal to the daily
average Federal Funds  Effective  Rate.  Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

     2.16  Illegality.  Notwithstanding  any  other  provision  herein,  if  the
adoption of or any change in any Requirement of Law or in the  interpretation or
application  thereof  shall make it unlawful  for any Lender to make or maintain
Eurodollar  Loans as contemplated by this Agreement,  (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Base Rate Loans to Eurodollar Loans shall forthwith be suspended and (b)
such Lender's  Loans then  outstanding  as Eurodollar  Loans,  if any,  shall be
converted  automatically  to Base Rate Loans on the respective  last days of the
then current  Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto,  the Borrower shall pay to such Lender such amounts,  if any, as may be
required pursuant to Section 2.19.

     2.17  Requirements  of Law. (a) If after the date hereof the adoption of or
any change in any  Requirement  of Law or in the  interpretation  or application
thereof or  compliance  by any Lender with any request or directive  (whether or
not  having  the  force of law)  from  any  central  bank or other  Governmental
Authority made subsequent to the date hereof:

     (i shall subject any Lender to any tax of any kind  whatsoever with respect
to this  Agreement,  any Note,  any Letter of  Credit,  any  Application  or any
Eurodollar  Loan made by it, or change the basis of taxation of payments to such
Lender in respect  thereof (except for taxes covered by Section 2.18 and changes
in the rate of tax (whether characterized as income,  franchise or other tax) on
the overall net income of such Lender);

     (ii shall impose,  modify or hold applicable any reserve,  special deposit,
compulsory loan or similar requirement against assets held by, deposits or other
liabilities  in or for the account of,  advances,  loans or other  extensions of
credit by, or any other acquisition of funds by, any office of such Lender which
is not otherwise included in the determination of the Eurodollar Rate hereunder;
or

     (iii shall impose on such Lender any other condition;

     and the  result of any of the  foregoing  is to  increase  the cost to such
Lender,  by an  amount  which  such  Lender  deems to be  material,  of  making,
converting  into,  continuing  or  maintaining  Eurodollar  Loans or  issuing or
participating in Letters of Credit, or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender,  upon its demand,  any additional  amounts  necessary to compensate such
Lender  on an  after-tax  basis  for  such  increased  cost  or  reduced  amount
receivable.  If any Lender  becomes  entitled  to claim any  additional  amounts
pursuant to this Section 2.17,  it shall  promptly  notify the Borrower  (with a
copy to the Administrative  Agent) of the event by reason of which it has become
so entitled.

     (b) If any Lender shall have  determined that the adoption of or any change
in any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by such Lender or any corporation  controlling
such Lender with any request or directive regarding capital adequacy (whether or
not having the force of law) from any Governmental  Authority made subsequent to
the date  hereof  shall have the effect of  reducing  the rate of return on such
Lender's  or such  corporation's  capital as a  consequence  of its  obligations
hereunder  or under or in respect of any Letter of Credit to a level  below that
which such Lender or such corporation could have achieved but for such adoption,
change  or  compliance   (taking  into   consideration  such  Lender's  or  such
corporation's  policies with respect to capital adequacy) by an amount deemed by
such Lender to be material,  then from time to time,  after  submission  by such
Lender to the Borrower  (with a copy to the  Administrative  Agent) of a written
request  therefor,  the Borrower shall pay to such Lender such additional amount
or  amounts  as will  compensate  such  Lender  on an  after-tax  basis for such
reduction.

     (c) If any Lender becomes entitled to claim any additional amounts pursuant
to this  subsection,  it shall promptly  notify the Borrower (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.
A certificate  as to any  additional  amounts  payable  pursuant to this Section
2.17,  together  with a  calculation  thereof  in  reasonable  detail,  shall be
submitted  by  the  affected  Lender  to  the  Borrower  (with  a  copy  to  the
Administrative Agent) and such certificate shall be conclusive in the absence of
manifest error.  The  obligations of the Borrower  pursuant to this Section 2.17
shall survive the termination of this Agreement and the payment of the Notes and
all other amounts payable hereunder.

     2.18 Taxes.  (a) All payments made by the Borrower under this Agreement and
the Notes shall be made free and clear of, and without  deduction or withholding
for or on  account  of,  any  present or future  income,  stamp or other  taxes,
levies,  imposts,  duties,  charges,  fees,  deductions or withholdings,  now or
hereafter imposed, levied,  collected,  withheld or assessed by any Governmental
Authority,  excluding net income taxes and franchise  taxes  (imposed in lieu of
net income taxes) imposed on the Administrative  Agent or any Lender as a result
of a present  or former  connection  between  the  Administrative  Agent or such
Lender and the jurisdiction of the Governmental  Authority  imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such  connection  arising  solely from the  Administrative  Agent or such Lender
having  executed,  delivered or performed its  obligations or received a payment
under,  or enforced,  this  Agreement or any other Loan  Document).  If any such
non-excluded  taxes,  levies,  imposts,  duties,  charges,  fees,  deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to the Administrative  Agent or any Lender hereunder or under the Notes,
the  amounts so  payable to the  Administrative  Agent or such  Lender  shall be
increased to the extent necessary to yield to the  Administrative  Agent or such
Lender  (after  payment of all  Non-Excluded  Taxes)  interest or any such other
amounts  payable  hereunder  at the rates or in the  amounts  specified  in this
Agreement  and the  Notes,  provided,  however,  that the  Borrower  shall  make
payments  net of and after  deduction  for  Non-Excluded  Taxes and shall not be
required to increase any such amounts payable to any Non-U.S. Lender (as defined
below) that fails to comply with  Section  2.18(b).  Whenever  any  Non-Excluded
Taxes are  payable by the  Borrower,  as promptly  as  possible  thereafter  the
Borrower shall send to the  Administrative  Agent for its own account or for the
account of such  Lender,  as the case may be, a  certified  copy of an  original
official  receipt  received by the  Borrower  showing  payment  thereof.  If the
Borrower fails to pay any Non-Excluded  Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other  required   documentary   evidence,   the  Borrower  shall  indemnify  the
Administrative  Agent and the Lenders for any  Non-Excluded  Taxes,  incremental
taxes, interest or penalties that may become payable by the Administrative Agent
or any Lender as a result of any such  failure.  The  agreements in this Section
2.18 shall  survive the  termination  of this  Agreement  and the payment of the
Notes and all other amounts payable hereunder.

     (b) Each Lender (or  Transferee)  that is not a corporation  or partnership
created or organized in or under the laws of the United States,  any estate that
is subject to federal income taxation  regardless of the source of its income or
any trust  which is  subject  to the  supervision  of a court  within the United
States and the control of a United  States  fiduciary  as  described  in section
7701(a)(30) of the Code (a "Non-U.S.  Lender") shall deliver to the Borrower and
the Administrative  Agent (or, in the case of a Participant,  to the Lender from
which the related participation shall have been purchased) on or before the date
on which it becomes a party to this Agreement (or, in the case of a Participant,
on  or  before  the  date  on  which  such  Participant  purchases  the  related
participation) either:

     (A) (x) two duly  completed  and signed copies of either  Internal  Revenue
Service  Form 1001  (relating  to such  Non-U.S.  Lender and  entitling  it to a
complete  exemption from withholding of U.S. Taxes on all amounts to be received
by such Non-U.S. Lender pursuant to this Agreement and the other Loan Documents)
or Form 4224  (relating  to all amounts to be received by such  Non-U.S.  Lender
pursuant to this  Agreement  and the other Loan  Documents),  or  successor  and
related  applicable  forms,  as the case may be, and (y) two duly  completed and
signed  copies of Internal  Revenue  Service Form W-8 or W-9, or  successor  and
related applicable forms, as the case may be; or

     (B) in the  case of a  Non-U.S.  Lender  that is not a  "bank"  within  the
meaning of Section  881(c)(3)(A)  of the Code and that does not comply  with the
requirements of clause (A) hereof,  (x) a statement in the form of Exhibit F (or
such other form of statement as shall be reasonably requested by the Borrower or
the  Administrative  Agent from time to time) to the effect  that such  Non-U.S.
Lender is eligible for a complete exemption from withholding of U.S. Taxes under
Code Section  871(h) or 881(c),  and (y) two duly completed and signed copies of
Internal Revenue Service Form W-8 or successor and related applicable form.

     Further,  each  Non-U.S.  Lender  agrees to deliver to the Borrower and the
Administrative  Agent, and if applicable,  the assigning Lender (or, in the case
of a Participant,  to the Lender from which the related participation shall have
been purchased) two further duly completed and signed copies of such Forms 1001,
4224, W-8 or W-9, as the case may be, or successor and related applicable forms,
on or  before  the date that any such  form  expires  or  becomes  obsolete  and
promptly  after the  occurrence  of any event  requiring  a change from the most
recent form(s) previously  delivered by it to the Borrower or the Administrative
Agent (or,  in the case of a  Participant,  to the Lender from which the related
participation  shall have been purchased) in accordance  with applicable  United
States  laws and  regulations;  unless,  in any such case,  any change in law or
regulation  has occurred  subsequent  to the date such Lender  became a party to
this  Agreement  (or in the  case  of a  Participant,  the  date on  which  such
Participant  purchased the related  participation)  which renders all such forms
inapplicable or which would prevent such Lender (or  Participant)  from properly
completing  and  executing  any such form  with  respect  to it and such  Lender
promptly notifies the Borrower and the Administrative  Agent (or, in the case of
a Participant,  the Lender from which the related  participation shall have been
purchased) if it is no longer able to deliver,  or if it is required to withdraw
or cancel,  any form or  statement  previously  delivered by it pursuant to this
Section 2.18(b). A Non-U.S.  Lender shall not be required to deliver any form or
statement  pursuant  to the  immediately  preceding  sentences  in this  Section
2.18(b)  that such  Non-U.S.  Lender is not  legally  able to deliver  (it being
understood  and agreed that the Borrower  shall  withhold or deduct such amounts
from any payments  made to such  Non-U.S.  Lender that the  Borrower  reasonably
determines  are required by law and that  payments  resulting  from a failure to
comply with this  paragraph  (b) shall not be subject to payment or indemnity by
the Borrower pursuant to Section 2.18(a)).

     2.19  Indemnity.  The Borrower  agrees to indemnify each Lender and to hold
each Lender  harmless  from any loss or expense which such Lender may sustain or
incur as a consequence  of (a)default by the Borrower in making a borrowing of,
conversion into or continuation of Eurodollar Loans after the Borrower has given
a  notice  requesting  the  same  in  accordance  with  the  provisions  of this
Agreement,  (b)  default  by the  Borrower  in making any  prepayment  after the
Borrower has given a notice  thereof in accordance  with the  provisions of this
Agreement or (c) the making of a prepayment of  Eurodollar  Loans on a day which
is  not  the  last  day  of  an  Interest  Period  with  respect  thereto.  Such
indemnification  shall not exceed the sum of (i) an  amount equal to the excess,
if any, of (A) the amount of interest  which would have accrued on the amount so
prepaid,  or not so borrowed,  converted or  continued,  for the period from the
date of such prepayment or of such failure to borrow, convert or continue to the
last day of such  Interest  Period  (or,  in the case of a  failure  to  borrow,
convert or continue,  the Interest  Period that would have commenced on the date
of such failure) in each case at the applicable  rate of interest for such Loans
provided for herein (excluding, however, the Applicable Margin included therein,
if any) over (B) the  amount  of  interest  (as  reasonably  determined  by such
Lender)  which would have  accrued to such Lender on such amount by placing such
amount on deposit for a comparable  period with leading  banks in the  interbank
eurodollar  market plus (ii) any  transaction costs of such Lender in connection
with the related  funding or  redeployment  of funds.  A  certificate  as to any
amounts  payable  pursuant to this Section  2.19,  together  with a  calculation
thereof in reasonable detail, shall be submitted to the Borrower by any affected
Lender and such  certificate  shall be  conclusive  in the  absence of  manifest
error.  This covenant  shall survive the  termination  of this Agreement and the
payment of the Notes and all other amounts payable hereunder.

     2.20 Change of Lending Office. Each Lender agrees that, upon the occurrence
of any event giving rise to the operation of Section 2.16,  2.17(a) or 2.18 with
respect to such Lender,  it will, if requested by the Borrower,  use  reasonable
efforts (subject to overall policy  considerations  of such Lender) to designate
another  lending  office for any Loans affected by such event with the object of
avoiding the consequences of such event;  provided that such designation is made
on terms that,  in the sole  judgment of such Lender,  cause such Lender and its
lending  office(s)  to  suffer  no  material   economic,   legal  or  regulatory
disadvantage,  and  provided,  further,  that nothing in this Section 2.20 shall
affect or postpone any of the  obligations  of the Borrower or the rights of any
Lender pursuant to Section 2.16, 2.17(a) or 2.18.

     2.21 Use of Proceeds. The Borrower shall use the proceeds of the Loans only
in the manner expressly contemplated by Section 4.16.

     2.22  Replacement  of  Lenders.  If no Event of Default  then  exists,  the
Borrower  may  replace  any Lender (the  "Replaced  Lender") if an event  occurs
giving rise to the operation of Section 2.16 or Section  2.17,  which results in
the  Replaced  Lender  charging to Borrower  increased  costs in excess of those
being  generally  charged by the other  Lenders  and such  Lender is not able to
eliminate the increased  costs  pursuant to Section  2.20.  The Replaced  Lender
shall be  replaced  with one or more  banks,  financial  institutions,  or other
entities which are  reasonably  acceptable to the  Administrative  Agent (each a
"Replacement Lender") under the terms set out in Section 10.6(c). Upon execution
of the  Assignment  and Acceptance  referred to in Section  10.6(c),  payment of
amounts referred to in Section 10.6(c),  and delivery to the Replacement  Lender
of the appropriate  Note or Notes executed by Borrower,  the Replacement  Lender
shall become a Lender  under this  Agreement  and the  Replaced  Lender shall no
longer be a Lender under this Agreement,  except with respect to indemnification
provisions under this Agreement, which shall survive as to such Replaced Lender.


                          SECTION 3. LETTERS OF CREDIT

     3.1 L/C Commitment.  (a) Prior to the date hereof,  Norwest Bank has issued
the Letters of Credit listed on Schedule 3.1 (the "Existing Letters of Credit"),
and subject to the terms and conditions hereof, the Lender designated as Issuing
Lender  hereunder,  in reliance on the agreements of the other Revolving  Credit
Lenders set forth in Section 3.4(a), agrees to issue letters of credit (together
with the Existing Letters of Credit, "Letters of Credit") for the account of the
Borrower,  or for  the  joint  and  several  account  of the  Borrower  and  any
Subsidiary, on any Business Day during the Revolving Credit Commitment Period in
such form as may be requested by the Borrower and approved  from time to time by
the  Issuing  Lender;  provided,  that  such  approval  may not be  unreasonably
withheld, delayed or conditioned; and provided, further, that the Issuing Lender
shall have no  obligation  to issue any Letter of Credit if, after giving effect
to such  issuance,  (i) the L/C  Obligations  would exceed the L/C Commitment or
(ii) the Aggregate  Outstanding  Revolving Extensions of Credit would exceed the
aggregate  Revolving  Credit  Commitments.  Each  Letter of Credit  shall (i) be
denominated in Dollars,  (ii) be either (x) a standby letter of credit issued to
support (I) obligations of the Borrower or any of its  Subsidiaries,  contingent
or  otherwise,  which  finance  the  working  capital or  business  needs of the
Borrower or its Subsidiaries or (II) performance obligations of the Borrower and
its Subsidiaries,  in each case,  incurred in the ordinary course of business (a
"Standby Letter of Credit"),  or (y) a commercial letter of credit in respect of
the purchase of goods or services by the Borrower or any of its  Subsidiaries in
the ordinary course of business (a "Commercial Letter of Credit"),  (iii) expire
no later than five Business Days prior to the Revolving Credit  Termination Date
and (iv) expire no later than 365 days after its date of issuance, provided that
any Letter of Credit with a 365-day duration may provide for the renewal thereof
at the election of the Borrower (in accordance with procedures to be established
by the Issuing  Lender) for additional  365-day  periods (which shall not expire
later than five Business Days prior to the Revolving Credit  Termination  Date).
(b) Each Letter of Credit  issued after the Closing Date shall be subject to the
Uniform Customs and, to the extent not inconsistent  therewith,  the laws of the
State of New York.

     3.2 Procedure for Issuance of Letter of Credit.  The Borrower may from time
to time request that the Issuing  Lender issue a Letter of Credit by  delivering
to the Issuing Lender at its address for notices specified herein an Application
therefor,  completed to the  satisfaction of the Issuing Lender,  and such other
certificates,  documents and other papers and  information as the Issuing Lender
may request.  Upon receipt of any  Application,  the Issuing Lender will process
such  Application  and  the   certificates,   documents  and  other  papers  and
information  delivered  to it in  connection  therewith in  accordance  with its
customary  procedures and shall  promptly  issue the Letter of Credit  requested
thereby  (but in no event  shall the  Issuing  Lender be  required  to issue any
Letter of Credit  earlier  than three  Business  Days  after its  receipt of the
Application therefor and all such other certificates, documents and other papers
and  information  relating  thereto) by issuing  the  original of such Letter of
Credit  to the  beneficiary  thereof  or as  otherwise  may be  agreed to by the
Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such
Letter of Credit to the Borrower promptly  following the issuance  thereof.  The
Issuing Lender shall promptly furnish to the  Administrative  Agent, which shall
in turn promptly furnish to the Lenders,  notice of the issuance of each Standby
Letter of Credit  (including the amount thereof).  On each L/C Fee Payment Date,
the Issuing Lender shall promptly  furnish to the  Administrative  Agent,  which
shall in turn  promptly  furnish to the Lenders,  notice of the  aggregate  face
amount of the Commercial Letters of Credit outstanding on such date.

     3.3 Fees,  Commissions  and Other Charges.  (a) The Borrower agrees that it
will pay a commission on all  outstanding  Letters of Credit at a rate per annum
equal to 1/8 of 1% above the  Applicable  Margin then in effect with  respect to
Revolving Credit Loans that are Eurodollar Loans of the face amount of each such
Letter of Credit,  of which 1/8 of 1% per annum  will be a fronting  fee for the
account of the Issuing  Lender,  and the remainder  will be shared ratably among
the  Revolving   Credit  Lenders  in  accordance  with  their  Revolving  Credit
Percentages, payable quarterly in arrears on each L/C Fee Payment Date after the
issuance date.

     (b) In addition to the foregoing fees and commissions,  the Borrower agrees
that it shall pay or reimburse the Issuing Lender  promptly upon demand for such
normal  and  customary  costs and  expenses  as are  incurred  or charged by the
Issuing Lender in issuing, negotiating, effecting payment under, or amending any
Letter of Credit.

     (c) The Administrative Agent shall, promptly following its receipt thereof,
distribute  to the  Issuing  Lender  and  the  L/C  Participants  all  fees  and
commissions  received by the Administrative  Agent for their respective accounts
pursuant to this Section.

     3.4 L/C Participation.  (a) Effective on the Closing Date in respect of the
Existing  Letters of Credit,  and  effective on the date of issuance  thereof in
respect of each Letter of Credit issued  hereunder  after the Closing Date,  the
Issuing Lender in respect of each Letter of Credit  irrevocably  agrees to grant
and hereby grants to each L/C Participant, and, to induce such Issuing Lender to
issue Letters of Credit hereunder,  each L/C Participant  irrevocably  agrees to
accept and purchase and hereby accepts and purchases  from such Issuing  Lender,
on the terms and conditions  hereinafter  stated, for such L/C Participant's own
account and risk an undivided interest equal to such L/C Participant's Revolving
Credit  Percentage in such Issuing  Lender's  obligations  and rights under such
Letter of  Credit  and the  amount of each  draft  paid by such  Issuing  Lender
thereunder.  Each L/C Participant  unconditionally  and irrevocably  agrees with
such Issuing Lender in respect of each Letter of Credit that, if a draft is paid
under any Letter of Credit issued by such Issuing  Lender for which such Issuing
Lender is not reimbursed in full by the Borrower in accordance with the terms of
this  Agreement,  such L/C  Participant  shall pay to such  Issuing  Lender upon
demand at such Issuing Lender's  address for notices  specified herein an amount
equal to such L/C  Participant's  Revolving  Credit  Percentage of the amount of
such draft, or any part thereof, which is not so reimbursed.

     (b) If any amount required to be paid by any L/C Participant to the Issuing
Lender pursuant to Section 3.4(a) in respect of any unreimbursed  portion of any
payment  made by the  Issuing  Lender  under any Letter of Credit is paid to the
Issuing  Lender  within three  Business Days after the date such payment is due,
such L/C  Participant  shall pay to the Issuing Lender on demand an amount equal
to the product of (i) such amount,  times (ii) the daily  average  Federal Funds
Effective  Rate during the period from and  including  the date such  payment is
required  to the date on which such  payment  is  immediately  available  to the
Issuing  Lender,  times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the  denominator of which is 360. If any
such  amount  required  to be paid by any L/C  Participant  pursuant  to Section
3.4(a) is not made  available  to the  Issuing  Lender  by such L/C  Participant
within  three  Business  Days after the date such  payment is due,  the  Issuing
Lender shall be entitled to recover from such L/C Participant,  on demand,  such
amount with interest thereon calculated from such due date at the rate per annum
applicable  to  Revolving  Credit  Loans that are Base Rate Loans  hereunder.  A
certificate of the Issuing Lender  submitted to any L/C Participant with respect
to any amounts  owing under this Section  shall be  conclusive in the absence of
manifest error.

     (c) Whenever,  at any time after the Issuing  Lender has made payment under
any  Letter of Credit and has  received  from any L/C  Participant  its pro rata
share of such payment in  accordance  with Section  3.4(a),  the Issuing  Lender
receives any payment related to such Letter of Credit (whether directly from the
Borrower or otherwise,  including  proceeds of collateral applied thereto by the
Issuing  Lender),  or any payment of interest  on account  thereof,  the Issuing
Lender  will  distribute  to such L/C  Participant  its pro rata share  thereof;
provided that in the event that any such payment  received by the Issuing Lender
shall be required to be returned  by the Issuing  Lender,  such L/C  Participant
shall return to the Issuing Lender the portion thereof previously distributed by
the Issuing Lender to it.

     3.5  Reimbursement  Obligation  of the  Borrower.  The  Borrower  agrees to
reimburse the Issuing Lender on each date on which the Issuing  Lender  notifies
the  Borrower  of the date and amount of a draft  presented  under any Letter of
Credit and paid by the  Issuing  Lender for the amount of (a) such draft so paid
and (b) any taxes,  fees,  charges or other  costs or  expenses  incurred by the
Issuing Lender in connection with such payment.  Each such payment shall be made
to the Issuing  Lender at its address  for  notices  specified  herein in lawful
money of the United States and in immediately available funds. Interest shall be
payable to the  Issuing  Lender on any and all amounts  drawn  under  Letters of
Credit from the date of such drawing  until the date three  Business  Days after
receipt by the Borrower from the Issuing Lender of notice of such drawing at the
rate set forth in Section  2.12(b) for Revolving  Credit Loans,  and  thereafter
until payment in full at the rate set forth in Section 2.12(c).

     3.6 Obligations Absolute.  The Borrower's  obligations under this Section 3
shall  be  absolute  and  unconditional  under  any  and all  circumstances  and
irrespective  of any  setoff,  counterclaim  or  defense  to  payment  which the
Borrower may have or have had against the Issuing  Lender,  any beneficiary of a
Letter of Credit or any other Person.  The Borrower also agrees with the Issuing
Lender that, subject to Section 3.7, the Issuing Lender shall not be responsible
for, and the Borrower's Reimbursement Obligations under Section 3.5 shall not be
affected by, among other things,  the validity or genuineness of documents or of
any endorsements  thereon,  even though such documents shall in fact prove to be
invalid,  fraudulent or forged, or any dispute between or among the Borrower and
any  beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be  transferred or any claims  whatsoever of the Borrower  against
any  beneficiary  of such Letter of Credit or any such  transferee.  The Issuing
Lender  shall not be liable for any error,  omission,  interruption  or delay in
transmission,   dispatch  or   delivery  of  any  message  or  advice,   however
transmitted,  in  connection  with any  Letter of  Credit,  except for errors or
omissions  found by a final and  nonappealable  decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
the Issuing Lender.  The Borrower agrees that any action taken or omitted by the
Issuing  Lender under or in connection  with any Letter of Credit or the related
drafts or  documents,  if done in the  absence  of gross  negligence  or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial  Code of the State of New York,  shall be binding on the Borrower and
shall not result in any liability of the Issuing Lender to the Borrower.

     3.7 Letter of Credit Payments.  If any draft shall be presented for payment
under any  Letter of  Credit,  the  Issuing  Lender  shall  promptly  notify the
Borrower  of the date and amount  thereof.  The  responsibility  of the  Issuing
Lender to the Borrower in connection  with any draft presented for payment under
any Letter of Credit  shall,  in addition to any  payment  obligation  expressly
provided  for in such Letter of Credit,  be to determine  whether the  documents
(including each draft)  delivered under such Letter of Credit in connection with
such presentment are substantially in conformity with such Letter of Credit.

     3.8  Applications.  To the extent  that any  provision  of any  Application
related  to any Letter of Credit is  inconsistent  with the  provisions  of this
Section 3, the provisions of this Section 3 shall apply.


                    SECTION 4. REPRESENTATIONS AND WARRANTIES

     To induce the Arranger,  the Administrative Agent, the Collateral Agent and
the  Lenders  to enter  into this  Agreement  and to make the Loans and issue or
participate  in the  Letters of  Credit,  the  Borrower  hereby  represents  and
warrants to the Arranger,  the  Administrative  Agent,  the Collateral Agent and
each  Lender  that:  4.1  Financial  Condition.  (a)  The  unaudited  pro  forma
consolidated  balance  sheet of the Borrower as at December 31, 1996  (including
the notes  thereto)  (the  "Pro  Forma  Balance  Sheet"),  copies of which  have
heretofore been furnished to each Lender, has been prepared giving effect (as if
such events had occurred on such date) to the  borrowings  under this  Agreement
contemplated to be made on the Closing Date and the use of proceeds  thereof and
the payment of estimated  fees and  expenses in  connection  therewith.  The Pro
Forma Balance Sheet has been prepared based on the best information available to
the  Borrower as of the date of  delivery  thereof  and  presents  fairly in all
material  respects on a pro forma  basis the  estimated  consolidated  financial
position  of the  Borrower as of  December 31,  1996,  assuming  that the events
specified in the preceding sentence had actually occurred at such date.

     (b) The audited  consolidated balance sheets of the Borrower as at June 30,
1996 and June 30, 1995 and the related audited consolidated statements of income
and of cash flows for the fiscal years ended on such dates,  reported on by KPMG
Peat Marwick LLP, copies of which have heretofore been furnished to each Lender,
are  complete  and correct  and  present  fairly in all  material  respects  the
consolidated  financial  condition  of the  Borrower as at such  dates,  and the
consolidated  results of operations and  consolidated  cash flows for the fiscal
years then ended. The unaudited consolidated balance sheet of the Borrower as at
March 31, 1997, and the related unaudited consolidated  statements of income and
of cash  flows for the  nine-month  period  ended on such date,  certified  by a
Responsible  Officer  of the  Borrower,  copies of which  have  heretofore  been
furnished  to each Lender,  are  complete and correct and present  fairly in all
material  respects the  consolidated  financial  condition of the Borrower as at
such date,  and the  consolidated  results of operations and  consolidated  cash
flows for the  nine-month  period then ended  (subject to normal  year-end audit
adjustments).

     All such financial statements  described in this Section 4.1(b),  including
the related  schedules and notes thereto,  have been prepared in accordance with
GAAP applied consistently throughout the periods involved (except as approved by
such accountants and as disclosed  therein).  Except for contingent  obligations
incurred in the ordinary course of business, the Borrower had at the date of the
most recent  audited  balance  sheet  referred to above no material  undisclosed
liabilities, Guarantee Obligations, contingent liability or liability for taxes,
nor any material  long-term  lease or unusual  forward or long-term  commitment,
including,  without  limitation,  any interest rate or foreign  currency swap or
exchange  transaction,  which is not  reflected in such balance  sheet or in the
notes  thereto.  During the period from June 30, 1996 to and  including the date
hereof there has been no sale,  transfer or other disposition by the Borrower or
any of its  Consolidated  Subsidiaries of any material part of their business or
property.

     4.2 No Change.  (a) Since June 30, 1996,  there has been no  development or
event which has had or could  reasonably be expected to have a Material  Adverse
Effect,  and  (b) during the period from June 30, 1996 to and including the date
hereof no dividends or other distributions have been declared, paid or made upon
the  Capital  Stock  of the  Borrower  nor has any of the  Capital  Stock of the
Borrower been redeemed,  retired,  purchased or otherwise  acquired for value by
the Borrower.

     4.3 Corporate  Existence;  Compliance with Law. Each Loan Party (a) is duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its  organization,  except (in the case of any Subsidiary) where
the failure to do so could not reasonably be expected to have a Material Adverse
Effect, (b) has the power and authority, and the legal right, to own and operate
its  property,  to lease the  property  it operates as lessee and to conduct the
business in which it is  currently  engaged,  except  where the failure to do so
could not reasonably be expected to have a Material Adverse Effect,  (c) is duly
qualified and in good  standing  under the laws of each  jurisdiction  where its
ownership,  lease or  operation  of  property  or the  conduct  of its  business
requires such  qualification,  except where the failure to be so qualified could
not  reasonably  be  expected  to have a Material  Adverse  Effect and (d) is in
compliance with all Requirements of Law except to the extent that the failure to
comply  therewith could not, in the aggregate,  reasonably be expected to have a
Material Adverse Effect.

     4.4 Corporate  Power;  Authorization;  Enforceable  Obligations.  Each Loan
Party has the power and  authority,  and the legal right,  to make,  deliver and
perform  each  Loan  Document  to  which it is a party  and,  in the case of the
Borrower, to borrow hereunder. Each Loan Party has taken all necessary action to
authorize the execution, delivery and performance of the Loan Documents to which
it is a party and, in the case of the Borrower,  to authorize the  borrowings on
the terms and conditions of this Agreement and the Notes. No material consent or
authorization  of, filing with,  notice to or other act by or in respect of, any
Governmental  Authority or any other Person is required in  connection  with the
transactions   contemplated   hereby,  the  borrowings  hereunder  or  with  the
execution, delivery,  performance,  validity or enforceability of this Agreement
or any of the Loan Documents, except for those obtained on or before the date of
this Agreement and listed in Schedule 4.4, and except the filings referred to in
Section 4.19.  Each Loan Document has been duly executed and delivered on behalf
of each Loan Party  thereto.  This  Agreement  constitutes,  and each other Loan
Document upon execution will constitute,  a legal,  valid and binding obligation
of each  Loan  Party  thereto,  enforceable  against  each  such  Loan  Party in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general  equitable  principles
(whether enforcement is sought by proceedings in equity or at law).

     4.5 No Legal Bar. The execution, delivery and performance of this Agreement
and the other Loan Documents,  the issuance of Letters of Credit, the borrowings
hereunder and the use of the proceeds  thereof will not violate any  Requirement
of Law or  Contractual  Obligation  of any Loan Party and will not result in, or
require,  the  creation  or  imposition  of any Lien on any of their  respective
properties or revenues  pursuant to any such  Requirement  of Law or Contractual
Obligation (other than the Liens created by the Security Documents).

     4.6 No Material Litigation.  No litigation,  investigation or proceeding of
or before  any  arbitrator  or  Governmental  Authority  is  pending  or, to the
knowledge of the  Borrower,  threatened by or against the Borrower or any of its
Subsidiaries  or against any of its or their  respective  properties or revenues
(a)  with  respect  to any  of the  Loan  Documents  or any of the  transactions
contemplated hereby or thereby or (b) which could reasonably be expected to have
a Material Adverse Effect.

     4.7 No Default.  Neither the  Borrower  nor any of its  Subsidiaries  is in
default  under or with  respect  to any of its  Contractual  Obligations  in any
respect which could reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

     4.8  Ownership  of Property;  Liens.  Each of the Borrower and its Domestic
Subsidiaries  has title in fee simple to, or a valid leasehold  interest in, all
its real property,  and good title to, or a valid leasehold interest in, all its
other  property,  and none of such  property  is subject  to any Lien  except as
permitted  by  Section  7.3.  The  Borrower  and its  Subsidiaries  (other  than
Servicios)  have no fee interests in any material  real property  other than the
Mortgaged  Property,  the Oil and Gas Properties and, as of the date hereof, the
real property described on Schedule 4.8.

     4.9 Intellectual  Property. The Borrower and each of its Subsidiaries owns,
or is licensed  to use,  all  trademarks,  tradenames,  copyrights,  technology,
know-how and  processes  necessary  for the conduct of its business as currently
conducted,  except  for those the  failure  to own or  license  which  could not
reasonably  be expected to have a Material  Adverse  Effect  (collectively,  the
"Intellectual  Property"). No material claim has been asserted and is pending by
any Person  challenging or questioning the use of any  Intellectual  Property or
the  validity  or  effectiveness  of any  Intellectual  Property,  nor  does the
Borrower  know  of any  valid  basis  for  any  such  claim.  To the  Borrower's
knowledge, the use of Intellectual Property by the Borrower and its Subsidiaries
does not  infringe  on the rights of any Person  where such  infringement  could
reasonably be expected to have a Material Adverse Effect.

     4.10 No  Burdensome  Restrictions.  No  Requirement  of Law or  Contractual
Obligation  of the  Borrower  or any of its  Subsidiaries  could  reasonably  be
expected to have a Material Adverse Effect.

     4.11 Taxes. Each of the Borrower and its Domestic Subsidiaries,  and to the
knowledge  of the  Borrower,  Servicios  has  filed or  caused  to be filed  all
material Federal, state and other tax returns which are required to be filed and
has paid  all  taxes  shown  to be due and  payable  on said  returns  or on any
assessments made against it or any of its property and all other taxes,  fees or
other charges imposed on it or any of its property by any Governmental Authority
(other than any the amount or validity of which are currently being contested in
good faith by  appropriate  proceedings  and with  respect to which  reserves in
conformity  with GAAP  have been  provided  on the  books of the  Borrower);  no
material  tax Lien has been filed;  and, to the  knowledge of the  Borrower,  no
claim is being asserted, with respect to any material tax, fee or other charge.

     4.12 Federal Regulations. Except as otherwise provided by Sections 4.16 and
7.7,  no part of the  proceeds  of any Loans  will be used for  "purchasing"  or
"carrying"  any "margin  stock"  within the  respective  meanings of each of the
quoted  terms under  Regulation  G or  Regulation U of the Board as now and from
time to time  hereafter in effect.  No part of the proceeds of any Loans will be
used for any purpose which  violates the  provisions of the  Regulations  of the
Board. If requested by any Lender or the Administrative Agent, the Borrower will
furnish to the Administrative Agent and each Lender a statement to the foregoing
effect  in  conformity  with  the  requirements  of FR Form  G-3 or FR Form  U-1
referred to in said Regulation G or Regulation U, as the case may be.

     4.13  ERISA.  Neither  a  Reportable  Event  nor  an  "accumulated  funding
deficiency"  (within  the meaning of  Section 412  of the Code or Section 302 of
ERISA) has occurred during the five-year  period prior to the date on which this
representation  is made or deemed made with  respect to any Plan,  and each Plan
has complied in all material  respects with the  applicable  provisions of ERISA
and the Code. No termination of a Single Employer Plan has occurred, and no Lien
in favor of the PBGC or a Plan has arisen,  during such five- year  period.  The
present value of all accrued  benefits under each Single Employer Plan (based on
those  assumptions  used to fund  such  Plans)  did not,  as of the last  annual
valuation date prior to the date on which this  representation is made or deemed
made,  exceed the value of the  assets of such Plan  allocable  to such  accrued
benefits by a material amount.  Neither the Borrower nor any Commonly Controlled
Entity has had a complete  or partial  withdrawal  from any  Multiemployer  Plan
which has  resulted  or could  reasonably  be  expected  to result in a material
liability  under ERISA,  and neither the  Borrower  nor any Commonly  Controlled
Entity  would  become  subject  to any  material  liability  under  ERISA if the
Borrower or any such Commonly Controlled Entity were to withdraw completely from
all Multiemployer Plans as of the valuation date most closely preceding the date
on which this  representation  is made or deemed made.  To the  knowledge of the
Borrower and the Commonly Controlled Entities,  no such Multiemployer Plan is in
Reorganization  or Insolvent.  The present value (determined using actuarial and
other  assumptions  which are reasonable in respect of the benefits provided and
the employees  participating) of the liability of the Borrower and each Commonly
Controlled  Entity for post retirement  benefits to be provided to their current
and former  employees under Plans which are welfare benefit plans (as defined in
Section 3(1) of ERISA) does not, in the  aggregate,  exceed the assets under all
such Plans allocable to such benefits by an amount in excess of $1,000,000.

     4.14  Investment  Company  Act;  Other  Regulations.  No Loan  Party  is an
"investment  company" within the meaning of the Investment  Company Act of 1940,
as amended.  No Loan Party is subject to  regulation  under any Federal or State
statute or  regulation  (other than  Regulation X of the Board) which limits its
ability to incur Indebtedness.

     4.15  Subsidiaries.  As of the date  hereof,  the  Subsidiaries  listed  on
Schedule  4.15  constitute  all  the  direct  or  indirect  Subsidiaries  of the
Borrower, and Schedule 4.15 shows, as to each such Subsidiary,  its jurisdiction
of its incorporation, its authorized capitalization and the ownership of Capital
Stock of such Subsidiary.

     4.16 Purpose of Loans;  Limitations on Use. The proceeds of the Loans shall
be used to refinance  indebtedness of the Loan Parties under the existing credit
facilities  described on Schedule 4.16 (the "Existing Credit Facilities") and to
pay related fees and expenses,  to finance  Permitted  Acquisitions  and capital
expenditures,  to  finance  the  repurchase  from  time to time the  outstanding
Capital Stock of the Borrower to the extent  permitted by subsection 7.7 and for
general  corporate  purposes of the  Borrower  and its  Subsidiaries  (including
Excluded  Subsidiaries) in the ordinary course of business;  provided,  that the
amount of proceeds of the Loans which may be used for Permitted  Acquisitions of
oil and gas  properties  shall be  limited  to an amount  equal to the lesser of
(a) $25,000,000 and (b) 65% of the value of the oil and gas properties of Odessa
Exploration   Incorporated   (after   giving   effect  to  any  such   Permitted
Acquisition), which value shall be calculated as the present value discounted at
10% of future net revenue  relating to all proved developed  producing  reserves
and proved undeveloped reserves from such properties.  In addition,  if at least
90% of the original outstanding principal amount of the Convertible Subordinated
Debentures  shall have been  converted  into common stock of the  Borrower,  the
Borrower may use  proceeds of the Loans to  repurchase  or redeem the  remaining
outstanding Convertible Subordinated Debentures as permitted by Section 7.10.

     4.17 Environmental  Matters.  Other than exceptions to any of the following
that could not, individually or in the aggregate, reasonably be expected to give
rise to a Material Adverse Effect:

     (a)  the  Borrower  and  each  of its  Subsidiaries:  (i)  are,  and to the
knowledge of the executive  management of the Borrower  within the period of all
applicable  statutes of limitation  have been, in compliance with all applicable
Environmental  Laws;  (ii) hold all  Environmental  Permits (each of which is in
full force and effect)  required for any of their current  operations or for any
property owned,  leased, or otherwise operated by any of them; (iii) are, and to
the knowledge of the executive  management of the Borrower  within the period of
all applicable statutes of limitation have been, in compliance with all of their
Environmental   Permits;  and  (iv)  reasonably  believe  that:  each  of  their
Environmental  Permits  required for their  continued  operations will be timely
renewed  and  complied   with,   without   material   expense;   any  additional
Environmental  Permits  that  may be  required  of any of them  will  be  timely
obtained and complied with,  without material  expense;  and compliance with any
Environmental Law that is or is reasonably expected by the Borrower's  executive
management  to become  applicable  to any of them will be  timely  attained  and
maintained, without material expense.

     (b) To the knowledge of the executive management of the Borrower, Materials
of  Environmental  Concern are not present at, on, under,  in, or about any real
property now or formerly owned, leased or operated by the Borrower or any of its
Subsidiaries  or at any  other  location  (including,  without  limitation,  any
location to which Materials of  Environmental  Concern have been sent for re-use
or recycling or for treatment,  storage,  or disposal) which could reasonably be
expected  to  (i)  give  rise  to  liability  of  the  Borrower  or  any  of its
Subsidiaries under any applicable Environmental Law or otherwise result in costs
to the Borrower or any of its Subsidiaries, or (ii) interfere with the continued
operations of the Borrower or any of its Subsidiaries,  or (iii) impair the fair
saleable  value of any real  property  owned or leased by the Borrower or any of
its Subsidiaries.
 
     (c) There is no judicial, administrative, or arbitral proceeding (including
any  notice  of  violation  or  alleged  violation)  under  or  relating  to any
Environmental Law to which the Borrower or any of its Subsidiaries is, or to the
knowledge of the executive  management of the Borrower will be, named as a party
that  is  pending  or,  to the  knowledge  of the  executive  management  of the
Borrower, threatened.

     (d) Neither the  Borrower  nor any of its  Subsidiaries  has  received  any
written  request for  information,  or been  notified  that it is a  potentially
responsible party under or relating to the federal  Comprehensive  Environmental
Response, Compensation, and Liability Act or any similar Environmental Law.

     (e) Neither the  Borrower nor any of its  Subsidiaries  has entered into or
agreed to any consent decree,  order, or settlement or other  agreement,  nor is
subject to any judgment,  decree, or order or other agreement,  in any judicial,
administrative,  arbitral,  or  other  forum,  relating  to  compliance  with or
liability under any Environmental Law.

     (f) To the knowledge of the executive  management of the Borrower,  neither
the Borrower nor any of its Subsidiaries has assumed or retained, by contract or
operation of law, any  liabilities of any kind,  fixed or  contingent,  known or
unknown, under or relating to any Environmental Law.

     For  purposes  of  Section  8, each of the  foregoing  representations  and
warranties  contained in this Section 4.17 that is qualified by the knowledge of
the executive management of the Borrower shall be deemed not to be so qualified.

     4.18 Accuracy of Information. No statement or information contained in this
Agreement,  any other Loan Document, the Confidential  Information Memorandum or
any other  document,  certificate  or statement  furnished to the Arranger,  the
Administrative  Agent or the Lenders,  by or on behalf of any Loan Party for use
in connection with the transactions  contemplated by this Agreement or the other
Loan Documents, contained as of the date such statement,  information,  document
or certificate was so furnished any untrue statement of a material fact or, with
all such statements and information  being taken as a whole,  omitted to state a
material  fact  necessary in order to make the  statements  contained  herein or
therein not misleading.  It is understood that no  representation or warranty is
made concerning the forecasts, estimates, pro forma information, projections and
statements  as  to  anticipated  future  performance  or  conditions,   and  the

financial  statements,  exhibits or  schedules,  except that as of the date such
forecasts,  estimates,  pro forma  information,  projections and statements were

such Pledged Securities and other  instruments,  negotiable  documents,  chattel
paper and money and the proceeds  thereof,  as security for the  Obligations (as

and  superior in right to any other  Person,  except for  inchoate tax liens for
obligations to be paid in the ordinary course of business.

     (b) The Master Guarantee and Collateral Agreement is effective to create in
favor of the  Collateral  Agent,  for the  benefit  of the  Lenders,  a security
interest  which has attached  (as that term is used in Section  9-203 of the New

thereof,  and when financing  statements in appropriate  form are properly filed
(with  all  required  filing  fees  being  paid)  in the  offices  specified  on
Schedule 4.19(b)  and, with respect to vehicles  included in the  Collateral and
covered by certificates of title issued by any State, when the security interest
of the  Collateral  Agent  has  been  noted  on such  certificate  of  title  in
accordance  with  the  certificate  of  title  laws of such  State,  the  Master
Guarantee and  Collateral  Agreement  shall  constitute a perfected Lien on, and

substantially all of such Collateral and the proceeds  thereof,  as security for

and properly  filed and recorded  (with all required  filing and recording  fees

Lien on, and  security  interest  in, all right,  title and interest of the Loan
Parties in the Mortgaged Property properly  described  therein,  as security for
the  Obligations (as defined in the relevant  Mortgage),  in each case prior and
superior  in right  to any  other  Person,  other  than  with  respect  to Liens
expressly permitted by Section 7.3.

and  maintain  any  and all  Environmental  Permits,  applicable  to any of them
insofar as any  failure to so comply,  obtain or  maintain  reasonably  could be
expected  to  adversely  affect the  Borrower  or any of its  Subsidiaries.  For
purposes of this  6.8(a),  noncompliance  by the  Borrower  with any  applicable
Environmental  Law or  Environmental  Permit shall be deemed not to constitute a
breach of this covenant  provided that, upon learning of any actual or suspected
noncompliance,  the  Borrower  shall  undertake  reasonable  efforts  to achieve
compliance, and provided further that, in any case, such non-

     compliance,  and any other noncompliance with applicable Environmental Law,
individually or in the aggregate,  could not reasonably be expected to give rise
to a Material Adverse Effect.

     (b) Promptly comply in all material respects with all orders and directives
of all Governmental  Authorities directed to the Borrower or any of its Domestic
Subsidiaries regarding Environmental Laws, other than such orders and directives
or parts  thereof  as are  being  contested  in good  faith  and by  appropriate
proceedings.

     (c) Within six months after the Closing Date, complete the development of a
program to promote  compliance with and to minimize prudently any liabilities or
potential  liabilities  under any  Environmental Law that may affect Borrower or
any of its Domestic Subsidiaries (the "Environmental Program") and implement the
Environmental  Program upon a reasonable schedule thereafter.  The Environmental
Program  shall be  developed  with the  assistance  of a  reputable  independent
environmental  consulting firm reasonably acceptable to the Administrative Agent
(an "Environmental  Consultant") or a qualified  employee of the Borrower.  Upon
the Administrative Agent's request, a reasonably detailed written description of
the Environmental  Program shall be provided to the Administrative  Agent, after
which, upon the Administrative  Agent's request,  Borrower shall confer with the
Administrative  Agent concerning any questions the Administrative Agent may have
about the Environmental Program.

     (d)  Prior  to  acquiring  any  ownership  or  leasehold  interest  in real
property,  or other  interest  in any  real  property  which  in the  Borrower's
reasonable  judgment  could  give  rise  to  significant   liability  under  any
Environmental  Law, obtain a written  environmental  assessment report regarding
the  environmental  condition of such real  property by a reputable  independent
environmental  consulting firm. Upon the request of the Administrative  Agent, a
copy of each such  environmental  assessment  report  shall be  delivered to the
Administrative Agent by the end of the calendar quarter in which the acquisition
closed,  together with a list of all  acquisitions of interests in real property
by the Borrower and the  Subsidiaries in such quarter.  Pursuant to this Section
6.8(d),  the  Administrative  Agent shall have the right, but shall not have any
duty, to obtain, review or discuss any such report.

     (e) Promptly upon the  Administrative  Agent's request if there has been an
Event  of  Default  which  has not  been  fully  and  timely  cured,  permit  an
Environmental  Consultant  whom  the  Administrative  Agent  in  its  discretion
designates  to  perform  an   environmental   assessment   (including,   without
limitation:   reviewing  documents;   interviewing  knowledgeable  persons;  and
sampling and analyzing soil, air, surface water, groundwater, and/or other media
in or about property owned or leased by the Borrower,  or on which operations of
the Borrower otherwise take place).  Such  environmental  assessment shall be in
form, scope, and substance reasonably  satisfactory to the Administrative Agent.
The  Borrower  shall  cooperate  fully  in the  conduct  of  such  environmental
assessment, and shall pay the costs of such environmental assessment immediately
upon  written  demand by the  Administrative  Agent.  Pursuant  to this  section
6.8(e),  the  Administrative  Agent shall have the right, but shall not have any
duty, to request and/or obtain such environmental assessment.

     6.9 Further  Assurances.  Promptly perform or cause to be performed any and
all acts and execute or cause to be executed any and all  documents  (including,
without limitation, financing statements and continuation statements) for filing
under the provisions of the Uniform  Commercial Code or any other Requirement of
Law  which  are  necessary  or  advisable  in  the  reasonable  judgment  of the
Collateral  Agent to maintain in favor of the Collateral  Agent, for the benefit
of the Lenders,  Liens on the  Collateral  that are duly perfected in accordance
with all applicable Requirements of Law.

     6.10 Additional  Collateral.  (a) With respect to any assets acquired after

advisable  to  cause  such  Lien to be duly  perfected  in  accordance  with all
applicable  Requirements of Law, including,  without  limitation,  the filing of
Uniform  Commercial Code financing  statements in such  jurisdictions  as may be
reasonably  requested  by the  Collateral  Agent,  and (iii) if requested by the
Collateral Agent, deliver to the Collateral Agent legal opinions relating to the
matters described in clauses (i) and (ii) immediately preceding,  which opinions

deliver to the  Collateral  Agent the  certificates  representing  such  Capital

(iii) cause such new  Domestic  Subsidiary  (A)to  become a party to the Master
Guarantee and Collateral  Agreement,  pursuant to documentation which is in form
and substance  reasonably  satisfactory to the Collateral Agent, and (B) to take
all actions  necessary or  advisable to cause the Lien created by such  security
agreement to be duly perfected in accordance with all applicable Requirements of
Law,  including,  without  limitation,  the  filing of Uniform  Commercial  Code
financing statements in such jurisdictions as may be reasonably requested by the
Collateral Agent, and (iv) if requested by the Collateral Agent,  deliver to the
Collateral  Agent legal  opinions  relating to the matters  described in clauses
(i), (ii) and (iii) immediately  preceding,  which opinions shall be in form and
substance and from counsel reasonably satisfactory to the Collateral Agent.

     (c) With respect to any fee interest in any real  property  acquired  after
the Closing Date by the Borrower or any of its  Domestic  Subsidiaries  having a
purchase price (or, if acquired  through a merger or stock  acquisition,  a fair
market value) in excess of $1,000,000,  promptly (i) execute and deliver a first
priority mortgage or deed of trust, as the case may be (subordinate only to such

easements,  rights of way,  restrictions and other similar  encumbrances as such
property may be subject at the time of acquisition),  in favor of the Collateral
Agent, for the benefit of the Lenders,  covering such real property, in form and
substance reasonably  satisfactory to the Collateral Agent, (ii) if requested by
the Collateral Agent,  provide the Lenders with any consents or estoppels deemed
necessary or advisable by the Collateral  Agent in connection with such mortgage

Agent,  deliver to the Collateral  Agent legal opinions  relating to the matters
described in the preceding clauses (i) and (ii), which opinions shall be in form

Notwithstanding  the  foregoing,  compliance  shall  not be  required  with  the
foregoing  provision  of this  paragraph  (c) in respect of any interest in real
property  which,  at the time of  acquisition  thereof  by the  Borrower  or its
Subsidiary, is subject to a legal or contractual restriction that would prohibit
the granting of a mortgage thereon to the Collateral Agent;  provided,  that the
aggregate book value of real property owned by the Borrower and its Subsidiaries
so subject may not exceed $5,000,000 at any time.

     (d) With respect to any Foreign  Subsidiary  created or acquired  after the
Closing Date by the Borrower or any of its Domestic  Subsidiaries,  promptly (i)
execute  and  deliver  to the  Collateral  Agent such  amendments  to the Master
Guarantee  and  Collateral  Agreement  (or  comparable   documentation)  as  the
Collateral  Agent deems  reasonably  necessary or advisable in order to grant to
the Collateral Agent, for the benefit of the Lenders, a perfected first priority
security interest in the Capital Stock (except for Liens permitted under Section
7.3) of such new Foreign Subsidiary which is owned by the Borrower or any of its
Domestic  Subsidiaries  (provided  that in no event  shall  more than 65% of the
Capital  Stock of any such new  Subsidiary  be required to be so pledged),  (ii)

Date by the Borrower or any of its Domestic Subsidiaries having a purchase price
(or, if acquired through a merger or stock acquisition,  a fair market value) in
excess of  $1,000,000  and which,  after giving effect to such  acquisition  and
assuming  that a perfected  first  priority Lien thereon were not granted to the
Collateral  Agent would result in the Collateral  Agent having a perfected first
priority Lien on less than 80% in value (calculated as provided in Section 4.24)
of the reserves  contained in all of the oil and gas  properties of the Borrower
and its Domestic Subsidiaries, promptly (i) execute and deliver a first priority
oil and gas  mortgage  (subordinate  only to such oil and gas  mortgages  as are
necessary to permit the Borrower or such  Domestic  Subsidiary  to purchase such
property but subject to such restrictions and other similar encumbrances as such
property may be subject at the time of acquisition),  in favor of the Collateral

written  in an amount  not less  than the  outstanding  principal  amount of the
indebtedness secured by such Mortgage which is reasonably allocable to such real
property or the maximum  limit of coverage  made  available  with respect to the
particular  type of property  under the National  Flood  Insurance  Act of 1968,

which documents shall be in proper form for filing,  registration or recordation
in each jurisdiction in which the filing, registration or recordation thereof is
so required or requested.

such  Indebtedness   constituting  a  Guarantee   Obligation  or  Interest  Rate
Protection  Agreement  Obligation) to become  payable;  provided that a default,
event or condition  described in clause (i), (ii) or (iii) of this paragraph (e)
shall  not at any time  constitute  an Event of  Default  under  this  Agreement
unless,  at such time,  one or more  defaults,  events or conditions of the type

Servicios)  shall take any action in  furtherance  of, or indicating its consent
to,  approval of, or  acquiescence  in, any of the acts set forth in clause (i),

any  "accumulated  funding  deficiency"  (as  defined in Section  302 of ERISA),
whether or not waived, shall exist with respect to any Plan or any Lien in favor
of the  PBGC or a Plan  shall  arise  on the  assets  of any  Loan  Party or any
Commonly  Controlled  Entity,  (iii) a Reportable Event shall occur with respect
to, or  proceedings  shall  commence to have a trustee  appointed,  or a trustee
shall be appointed,  to administer or to terminate,  any Single  Employer  Plan,
which  Reportable  Event or  commencement  of  proceedings  or  appointment of a

and in each case in clauses (i) through  (vi)  above,  such event or  condition,

     (j) Any Change of Control shall occur;

     then,  and in any such  event,  (A) if such  event  is an Event of  Default
specified  in clause  (i) or (ii) of  paragraph  (f) above  with  respect to the
Borrower,  automatically  the Commitments  shall  immediately  terminate and the
Loans  hereunder  (with  accrued  interest  thereon) and all other amounts owing
under  this  Agreement  and  the  other  Loan  Documents   (including,   without
limitation, all amounts of L/C Obligations,  whether or not the beneficiaries of
the then  outstanding  Letters of Credit  shall  have  presented  the  documents
required  thereunder) shall immediately become due and payable,  and (B) if such
event is any other Event of Default, either or both of the following actions may
be taken: (i) with the consent of the Required Lenders, the Administrative Agent
may, or upon the  request of the  Required  Lenders,  the  Administrative  Agent
shall,  by notice to the  Borrower  declare  the  Commitments  to be  terminated
forthwith,  whereupon the Commitments shall immediately terminate; and (ii) with
the consent of the Required Lenders,  the Administrative  Agent may, or upon the
request of the Required Lenders,  the  Administrative  Agent shall, by notice to
the Borrower,  declare the Loans hereunder (with accrued  interest  thereon) and
all other  amounts  owing  under this  Agreement  and the other  Loan  Documents
(including,  without limitation, all amounts of L/C Obligations,  whether or not
the beneficiaries of the then outstanding Letters of Credit shall have presented
the documents required  thereunder) to be due and payable  forthwith,  whereupon
the same shall immediately become due and payable.

     With respect to all Letters of Credit with respect to which presentment for
honor shall not have  occurred at the time of an  acceleration  pursuant to this
paragraph,  the Borrower shall at such time deposit in a cash collateral account
opened by the Administrative Agent an amount equal to the aggregate then undrawn
and  unexpired  amount of such  Letters  of  Credit.  Amounts  held in such cash
collateral account shall be applied by the  Administrative  Agent to the payment
of drafts drawn under such  Letters of Credit,  and the unused  portion  thereof
after all such Letters of Credit shall have expired or been fully drawn upon, if
any, shall be applied to repay other  obligations of the Borrower  hereunder and
under the other Loan  Documents.  After all such  Letters  of Credit  shall have
expired or been fully drawn upon, all Reimbursement  Obligations shall have been
satisfied  and all other  obligations  of the Borrower  hereunder  and under the
other Loan Documents shall have been paid in full, the balance,  if any, in such
cash collateral  account shall be returned to the Borrower (or such other Person
as may be lawfully entitled thereto). Except as expressly provided above in this
Section,  presentment,  demand,  protest  and all other  notices of any kind are
hereby expressly waived.

                              SECTION 9. THE AGENTS

     9.1 Appointment. Each Lender hereby irrevocably designates and appoints the
Agents as the  agents of such  Lender  under this  Agreement  and the other Loan
Documents,  and each Lender irrevocably authorizes each Agent, in such capacity,
to take such action on its behalf under the provisions of this Agreement and the
other Loan  Documents and to exercise such powers and perform such duties as are
expressly  delegated to such Agent by the terms of this  Agreement and the other
Loan  Documents,  together with such other powers as are  reasonably  incidental
thereto.  Notwithstanding  any  provision  to the  contrary  elsewhere  in  this
Agreement,  no Agent  shall have any duties or  responsibilities,  except  those
expressly set forth herein, or any fiduciary  relationship with any Lender,  and
no  implied  covenants,  functions,  responsibilities,  duties,  obligations  or
liabilities  shall be read into this  Agreement  or any other Loan  Document  or
otherwise exist against any Agent.

     9.2  Delegation  of Duties.  Each Agent may execute any of its duties under
this   Agreement  and  the  other  Loan   Documents  by  or  through  agents  or
attorneys-in-fact  and shall be  entitled  to advice of counsel  concerning  all
matters  pertaining  to such  duties.  No  Agent  shall be  responsible  for the
negligence or misconduct of any agents or attorneys  in-fact selected by it with
reasonable care.

     9.3 Exculpatory  Provisions.  Neither the Agents nor any of their officers,
directors,  employees,  agents,  attorneys-in-fact  or  Affiliates  shall be (i)
liable for any action lawfully taken or omitted to be taken by it or such Person
under or in connection with this Agreement or any other Loan Document (except to
the  extent  that any of the  foregoing  are found by a final and  nonappealable
decision of a court of competent  jurisdiction to have resulted from its or such
Person's own gross negligence or willful  misconduct) or (ii) responsible in any
manner to any of the Lenders for any recitals,  statements,  representations  or
warranties  made by any Loan  Party or any  officer  thereof  contained  in this
Agreement or any other Loan Document or in any certificate, report, statement or
other document referred to or provided for in, or received by any Agent under or
in connection  with, this Agreement or any other Loan Document or for the value,
validity,  effectiveness,  genuineness,  enforceability  or  sufficiency of this
Agreement or the Notes or any other Loan Document or for any failure of any Loan
Party a party thereto to perform its  obligations  hereunder or  thereunder.  No
Agent shall be under any  obligation to any Lender to ascertain or to inquire as
to the  observance  or  performance  of any of the  agreements  contained in, or
conditions  of, this  Agreement  or any other Loan  Document,  or to inspect the
properties, books or records of any Loan Party.

     9.4 Reliance by Agents.  Each Agent shall be entitled to rely, and shall be
fully protected in relying, upon any Note, writing, resolution, notice, consent,
certificate,  affidavit, letter, telecopy, telex or teletype message, statement,
order or other document or conversation believed by it to be genuine and correct
and to have been signed,  sent or made by the proper  Person or Persons and upon
advice and statements of legal counsel (including,  without limitation,  counsel
to the Borrower),  independent  accountants  and other experts  selected by such
Agent.  The Agents may deem and treat the payee of any Note as the owner thereof
for all purposes unless a written notice of assignment,  negotiation or transfer
thereof shall have been filed with the Administrative Agent. Each Agent shall be
fully  justified in failing or refusing to take any action under this  Agreement
or any  other  Loan  Document  unless  it shall  first  receive  such  advice or
concurrence of the Required Lenders (or, if so specified by this Agreement,  all
Lenders)  as it deems  appropriate  or it  shall  first  be  indemnified  to its
satisfaction  by the Lenders against any and all liability and expense which may
be incurred  by it by reason of taking or  continuing  to take any such  action,
provided that in no event shall the Lenders be obligated to indemnify the Agents
for any amounts described in the proviso to Section 9.7. Each Agent shall in all
cases be fully  protected in acting,  or in refraining  from acting,  under this
Agreement  and the other  Loan  Documents  in  accordance  with a request of the
Required Lenders (or, if so specified by this Agreement,  all Lenders), and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Lenders and all future holders of the Notes.

     9.5 Notice of Default. No Agent shall be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default hereunder unless such Agent
has  received  written  notice from a Lender or the  Borrower  referring to this
Agreement,  describing  such  Default or Event of Default and stating  that such
notice is a "notice  of  default".  In the event that the  Administrative  Agent
receives such a notice,  the  Administrative  Agent shall give notice thereof to
the Lenders.  The Administrative  Agent and the Collateral Agent shall take such
action with respect to such  Default or Event of Default as shall be  reasonably
directed by the Required  Lenders (or, if so  specified by this  Agreement,  all
Lenders);  provided  that  unless  and  until  the  Administrative  Agent or the
Collateral Agent shall have received such directions,  the Administrative  Agent
or the Collateral Agent may (but shall not be obligated to) take such action, or
refrain  from  taking  such  action,  with  respect to such  Default or Event of
Default as it shall deem advisable in the best interests of the Lenders.

     9.6  Non-Reliance  on  Agents  and Other  Lenders.  Each  Lender  expressly
acknowledges  that  neither  any  Agent  nor  any  of its  officers,  directors,
employees, agents,  attorneys-in-fact or Affiliates has made any representations
or warranties to it and that no act by the Agents hereafter taken, including any
review of the affairs of a Loan Party or any Affiliate of a Loan Party, shall be
deemed to constitute any  representation or warranty by any Agent to any Lender.
Each  Lender  represents  to each Agent that it has,  independently  and without
reliance  upon any Agent or any other  Lender,  and based on such  documents and
information  as it  has  deemed  appropriate,  made  its  own  appraisal  of and
investigation  into the  business,  operations,  property,  financial  and other
condition and creditworthiness of the Loan Parties and their Affiliates and made
its own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon any
Agent or any other Lender,  and based on such  documents and  information  as it
shall deem  appropriate at the time,  continue to make its own credit  analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents,  and to make such  investigation as it deems necessary
to inform itself as to the business,  operations,  property, financial and other
condition and creditworthiness of the Loan Parties and their Affiliates.  Except
for notices,  reports and other documents  expressly required to be furnished to
the Lenders by the Administrative Agent hereunder,  no Agent shall have any duty
or  responsibility  to provide any Lender  with any credit or other  information
concerning  the  business,   operations,   property,   condition  (financial  or
otherwise),  prospects or creditworthiness of any Loan Party or any Affiliate of
a Loan  Party  which may come into the  possession  of such  Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

     9.7  Indemnification.  The  Lenders  agree to  indemnify  each Agent in its
capacity  as such (to the extent not  reimbursed  by the  Borrower  and  without
limiting the  obligation of the Borrower to do so),  ratably  according to their
respective Commitments,  from and against any and all liabilities,  obligations,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements of any kind whatsoever  which may at any time (including,  without
limitation,  at any time  following  the  payment of the  Notes) be imposed  on,
incurred by or asserted  against any Agent in any way relating to or arising out
of, the  Commitments,  this  Agreement,  any of the other Loan  Documents or any
documents  contemplated by or referred to herein or therein or the  transactions
contemplated hereby or thereby or any action taken or omitted by any Agent under
or in  connection  with any of the  foregoing;  provided that no Lender shall be
liable for the payment of any portion of such liabilities,  obligations, losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
which are found by a final and  nonappealable  decision of a court of  competent
jurisdiction  to have  resulted  from such Agent's  gross  negligence or willful
misconduct.  The agreements in this Section 9.7 shall survive the payment of the
Notes and all other amounts payable hereunder.

     9.8 Agents in Their  Individual  Capacities.  Each Agent and its Affiliates
may make loans to,  accept  deposits  from and  generally  engage in any kind of
business  with any Loan Party as though  such Agent were not an Agent  hereunder
and under the other Loan Documents. With respect to its Loans made or renewed by
it and any Note issued to it and with respect to any Letter of Credit  issued or
participated  in by it, each Agent  shall have the same rights and powers  under
this  Agreement and the other Loan  Documents as any Lender and may exercise the
same as though it were not an Agent,  respectively,  and the terms  "Lender" and
"Lenders" shall include each Agent in their individual capacities.

     9.9 Successor Agents. The Administrative  Agent or the Collateral Agent may
resign as Administrative  Agent or Collateral Agent, as the case may be, upon 10
days' notice to the Lenders. If the Administrative Agent or the Collateral Agent
shall resign as  Administrative  Agent or Collateral  Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from among
the Lenders a successor agent in such capacity,  which successor  agent, so long
as no Default or Event of Default shall have occurred and be  continuing,  shall
have been approved by the Borrower  (which  approval  shall not be  unreasonably
withheld or  delayed),  whereupon  such  successor  agent  shall  succeed to the
rights,  powers and duties of the Administrative  Agent or the Collateral Agent,
as the case may be, hereunder. Effective upon such appointment and approval, the
terms  "Administrative  Agent" and "Collateral  Agent" shall mean such successor
agent,  and the former  Administrative  Agent's or  Collateral  Agent's  rights,
powers and duties as such shall be terminated,  without any other or further act
or deed on the part of such former  Administrative  Agent or Collateral Agent or
any of the  parties to this  Agreement  or any  holders of the Notes.  After any
retiring  Agent's  resignation as Agent,  the provisions of this Section 9 shall
inure to its benefit as to any actions  taken or omitted to be taken by it while
it was Agent under this Agreement and the other Loan Documents.

                            SECTION 10. MISCELLANEOUS

     10.1  Amendments  and  Waivers.  Neither  this  Agreement,  any other  Loan
Document,  nor any terms  hereof or  thereof  may be  amended,  supplemented  or
modified  except in accordance  with the  provisions  of this Section 10.1.  The
Required  Lenders  and each  Loan  Party  which is  party to the  relevant  Loan
Documents  may,  or,  with the  written  consent of the  Required  Lenders,  the
Administrative  Agent,  the Arranger and each Loan Party which is a party to the
relevant  Loan  Document  may,  from  time  to  time,  (a)  enter  into  written
amendments,  supplements or modifications hereto and to the other Loan Documents
for the purpose of adding any  provisions  to this  Agreement  or the other Loan
Documents  or  changing  in any manner the rights of the  Lenders or of the Loan
Parties  hereunder or thereunder or (b) waive,  on such terms and  conditions as
the Required Lenders or the Administrative  Agent and the Arranger,  as the case
may  be,  may  specify  in  such  instrument,  any of the  requirements  of this

consequences;  provided that no such waiver and no such amendment, supplement or
modification  shall  (i)  forgive  the  principal  amount of any Loan or any L/C
Obligation,  or extend the final  scheduled  date of  maturity  of any Loan,  or
reduce  the  stated  rate of any  interest,  fee or letter of credit  commission
payable  hereunder  or extend  the  scheduled  date of any  payment  thereof  or
increase  the amount or extend the  expiration  date of any  Lender's  Revolving
Credit Commitment,  or waive any mandatory  prepayment or make any change in the
application  of any  prepayment of the Loans  specified in the first sentence of
Section 2.9(f) or in Section  2.15(a),  or the right to refuse  prepayments  set
forth in the  penultimate  sentence  of Section  2.8,  in each case  without the

assignment  or transfer  by any Loan Party of any of its rights and  obligations

other  disposition  of assets  permitted by Section 7.6) or any guarantee of the
Obligations,  in each case, without the written consent of all the Lenders,  (v)
amend, modify or waive any provision of Section 9 without the written consent of
the Agents,  or (vi) amend,  modify or waive any  provision of Section 3 without
the  written  consent  of the  Issuing  Lender.  Any  such  waiver  and any such
amendment, supplement or modification shall apply equally to each of the Lenders
and shall be binding  upon the Loan  Parties,  the  Lenders,  the Agents and all
future holders of the Notes.  In the case of any waiver,  the Loan Parties,  the
Lenders and the Agents  shall be restored to their  former  position  and rights
hereunder  and under the  other  Loan  Documents,  and any  Default  or Event of
Default  waived  shall be  deemed to be cured  and not  continuing;  but no such
waiver shall extend to any  subsequent  or other  Default or Event of Default or
impair any right consequent thereon.

     provided that any notice,  request or demand to or upon the  Administrative
Agent or the Lenders pursuant to Section 2.2, 2.4, 2.7, 2.8 or 2.10 shall not be
effective until received.  Any notice or delivery to or from or consent required
of the Borrower  hereunder or pursuant to any other Loan Document may be made to
or by the Borrower.

     10.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising,  on the part of any Agent or any Lender, any right, remedy, power or
privilege  hereunder or under the other Loan Documents shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege  hereunder  preclude  any other or  further  exercise  thereof  or the
exercise of any other right, remedy, power or privilege.  The rights,  remedies,
powers and  privileges  herein  provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

     10.4 Survival.  All representations  and warranties made hereunder,  in the
other Loan  Documents and in any document,  certificate  or statement  delivered
pursuant  hereto or in  connection  herewith  shall  survive the  execution  and
delivery of this Agreement and the Notes and the making of the Loans hereunder.

     10.5  Payment of  Expenses  and Taxes.  The  Borrower  agrees (a) to pay or
reimburse the Agents for all their reasonable  out-of-pocket  costs and expenses
incurred in connection with the  development,  preparation and execution of, and
any amendment,  supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection  herewith or therewith,
and the consummation and administration of the transactions  contemplated hereby
and  thereby,   including,   without   limitation,   the  reasonable   fees  and
disbursements of counsel (including any local counsel) to the Agents, (b) to pay
or  reimburse  each Lender and each of the Agents for all its costs and expenses
incurred in connection  with the enforcement or preservation of any rights under
this  Agreement,  the  other  Loan  Documents  and  any  such  other  documents,
including,  without limitation, the fees and disbursements of counsel (including
the allocated fees and expenses of in-house  counsel) to each Lender and counsel
to the  Agents,  (c) to pay,  indemnify,  and hold each  Lender  and each  Agent
harmless from, any and all recording and filing fees and any and all liabilities
with respect to, or resulting from any delay in paying,  stamp, excise and other
taxes,  if any,  which may be payable or  determined to be payable in connection
with the execution and delivery of, or consummation or  administration of any of
the transactions  contemplated by, or any amendment,  supplement or modification
of, or any waiver or consent under or in respect of, this  Agreement,  the other
Loan Documents and any such other documents, and (d) to pay, indemnify, and hold
each Lender and each Agent and their respective officers,  directors,  trustees,
employees,  affiliates,  agents and controlling  persons (each, an "indemnitee")
harmless from and against any and all other  liabilities,  obligations,  losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
of any kind or  nature  whatsoever  with  respect  to the  execution,  delivery,
enforcement,  performance and  administration of this Agreement,  the other Loan
Documents and any such other documents,  including,  without limitation,  any of
the foregoing  relating to the use of proceeds of the Loans or the violation of,
noncompliance  with or liability under, any  Environmental Law applicable to the
Borrower,  any of its Subsidiaries,  any of its Excluded  Subsidiaries or any of
the  Properties  (all  the  foregoing  in this  clause  (d),  collectively,  the
"indemnified liabilities"),  provided that the Borrower shall have no obligation
hereunder to any  indemnitee  with  respect to  indemnified  liabilities  to the
extent  such  indemnified  liabilities  are found by a final  and  nonappealable
decision of a court of competent  jurisdiction  to have  resulted from the gross
negligence  or willful  misconduct  of such  indemnitee.  Without  limiting  the
foregoing,  and to the extent  permitted by applicable  law, the Borrower agrees
not to assert,  and hereby waives,  and to cause each of its Subsidiaries not to
assert  and to so waive,  all  rights for  contribution  or any other  rights of
recovery with respect to all claims,  demands,  penalties,  fines,  liabilities,
settlements,  damages,  costs and expenses of whatever kind or nature,  under or
related  to  Environmental  Laws,  that any of them  might  have by  statute  or
otherwise  against any  Indemnitee.  The  agreements  in this Section 10.5 shall
survive  repayment of the Notes and all other amounts payable  hereunder and the
termination  of the  Commitments  and, in the case of any Lender that may assign
any interest in its Commitments,  Loans or Letter of Credit interest  hereunder,
shall survive the making of such assignment, notwithstanding that such assigning
Lender may cease to be a "Lender" hereunder.

     10.6  Successors  and  Assigns;  Participation  and  Assignments.  (a) This
Agreement  shall be binding upon and inure to the benefit of the  Borrower,  the
Lenders,  the  Agents,  all  future  holders  of the Notes and their  respective
successors and assigns,  except that the Borrower may not assign or transfer any
of its rights or  obligations  under this  Agreement  without the prior  written
consent of each Lender.

     (b) Any Lender may,  without the consent of the  Borrower,  in the ordinary
course of its business and in accordance  with  applicable law, at any time sell
to one or more banks or other  entities  (each, a  "Participant")  participating
interests  in any Loan owing to such Lender,  any Note held by such Lender,  any
Commitment  of such Lender or any other  interest of such Lender  hereunder  and
under the other Loan  Documents.  In the event of any such sale by a Lender of a
participating  interest to a Participant,  such Lender's  obligations under this
Agreement to the other parties to this Agreement  shall remain  unchanged,  such
Lender shall remain solely responsible for the performance thereof,  such Lender
shall remain the holder of any such Note for all purposes  under this  Agreement
and the other Loan  Documents,  and the  Borrower and the  Administrative  Agent
shall  continue to deal solely and directly with such Lender in connection  with
such Lender's  rights and  obligations  under this  Agreement and the other Loan
Documents.  In no event shall any Participant under any such  participation have
any right to  approve  any  amendment  or waiver  of any  provision  of any Loan
Document, or any consent to any departure by any Loan Party therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest  on, the Notes or any fees payable  hereunder,  postpone the date of
the final  maturity of the Notes,  consent to the  assignment or transfer by the
Borrower of any of its rights and obligations under this Agreement and the other
Loan Documents,  release all or a substantial  portion of the Collateral  (other
than in connection  with any sale or other  disposition  of assets  permitted by
Section  7.6) or any  guarantee of the  Obligations,  in each case to the extent
subject to such  participation.  The Borrower agrees that if amounts outstanding
under  this  Agreement  and the  Notes  are due or  unpaid,  or shall  have been
declared or shall have become due and payable upon the occurrence of an Event of
Default,  each Participant  shall, to the maximum extent permitted by applicable
law,  be deemed to have the right of  setoff  in  respect  of its  participating
interest in amounts  owing under this  Agreement and any Note to the same extent
as if the amount of its  participating  interest were owing  directly to it as a
Lender under this  Agreement or any Note,  provided  that,  in  purchasing  such
participating interest, such Participant shall be deemed to have agreed to share
with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as
if it were a Lender  hereunder.  The Borrower also agrees that each  Participant
shall be entitled to the benefits of Sections  2.17,  2.18 and 2.19 with respect
to its  participation in the Commitments and the Loans  outstanding from time to
time as if it was a Lender;  provided  that, in the case of Section  2.18,  such
Participant  shall have  complied  with the  requirements  of said  Section  and
provided,  further, that no Participant shall be entitled to receive any greater
amount  pursuant to any such Section than the transferor  Lender would have been
entitled to receive in respect of the amount of the participation transferred by
such transferor Lender to such Participant had no such transfer occurred.

     (c)  Any  Lender  may,  in  the  ordinary  course  of its  business  and in
accordance  with applicable law, at any time and from time to time assign to any
Lender or any affiliate  thereof or any Person under common  management with any
such Lender or, with the consent of the Borrower,  the Administrative Agent, the
Arranger and, in the case of an assignment of Revolving Credit Commitments,  the
Issuing Lender (which, in each case, shall not be unreasonably withheld, delayed
or conditioned)  (provided that no such consent need be obtained by the Arranger
for a period of 120 days  following the Closing  Date),  to an additional  bank,
financial  institution  or other entity (an  "Assignee")  all or any part of its
rights and obligations under this Agreement, the Letters of Credit and the Notes
pursuant to an Assignment and Acceptance,  substantially  in the form of Exhibit
G,  executed by such  Assignee,  such  assigning  Lender (and, in the case of an
Assignee  that is not then a Lender or an  affiliate  thereof or a Person  under
common management with such Lender, by the Borrower,  the Administrative  Agent,
the Arranger and, in the case of an assignment of Revolving Credit  Commitments,
the Issuing Lender) and delivered to the Administrative Agent for its acceptance
and recording in the Register with a copy to the Arranger; provided that (except
with the consent of the Borrower, the Administrative Agent and the Arranger) (i)
no such  assignment  to an  Assignee  (other  than any  Lender or any  affiliate
thereof or any Person under common  management  with such Lender) shall be in an
aggregate principal amount of less than $5,000,000 (other than in the case of an
assignment of all of a Lender's  interests  under this  Agreement and the Notes)
and (ii) subsequent to any such assignment the assigning Lender shall not retain
an aggregate  principal amount of less than $5,000,000 in Commitments and Loans.
Such  assignment need not be ratable as among any Term Loan  Commitments  and/or
Term Loans and Revolving Credit Commitments and/or Revolving Credit Loans of the
assigning Lender. Upon such execution,  delivery, acceptance and recording, from
and  after  the  effective  date  determined  pursuant  to such  Assignment  and
Acceptance,  (x) the  Assignee  thereunder  shall be a party  hereto and, to the
extent  provided  in  such  Assignment  and  Acceptance,  have  the  rights  and
obligations of a Lender  hereunder  with a Commitment as set forth therein,  and
(y) the  assigning  Lender  thereunder  shall,  to the extent  provided  in such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance  covering all or the remaining
portion of an assigning  Lender's rights and  obligations  under this Agreement,
such  assigning  Lender shall cease to be a party hereto).  Notwithstanding  any
provision of this  paragraph (c) and  paragraph  (e) of this Section  10.6,  the
consent of the Borrower shall not be required for any assignment which occurs at
any time when any Event of Default shall have occurred and be continuing.

     (d) A Note and the  Obligation(s)  evidenced  thereby  may be  assigned  or
otherwise  transferred  in  whole  or in  part  only  by  registration  of  such
assignment or transfer of such Note and the  Obligation(s)  evidenced thereby on
the  Register  (and each Note shall  expressly so provide).  Any  assignment  or
transfer of all or part of such  Obligation(s)  and the Note(s)  evidencing  the
same shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Note(s) evidencing such Obligation(s), accompanied
by an Assignment and Acceptance duly executed by the holder of such Note(s), and
thereupon one or more new Note(s) in the same aggregate  principal  amount shall
be issued to the designated  Assignee(s)  and the old Notes(s) shall be returned
by the Administrative Agent to the Borrower marked "cancelled." No assignment of
a Note and the Obligation(s)  evidenced thereby shall be effective unless it has
been recorded in the Register as provided in this Section 10.6(d).

     (e) The  Administrative  Agent shall maintain at its address referred to in
Section  10.2 a copy of each  Assignment  and  Acceptance  delivered to it and a
register (the  "Register") for the recordation of the names and addresses of the
Lenders and the Commitment of, and principal  amount of the Loans owing to, each
Lender  from  time  to time  and  the  registered  owners  of the  Obligation(s)
evidenced by the Note(s).  The entries in the Register shall be  conclusive,  in
the absence of manifest error, and the Borrower,  the  Administrative  Agent and
the Lenders  shall treat each Person  whose name is recorded in the  Register as
the owner of the Loan or the Obligation evidenced by a Note recorded therein for
all purposes of this  Agreement.  The Register shall be available for inspection
by the Borrower or any Lender at any reasonable  time and from time to time upon
reasonable prior notice.

     (f) Upon  its  receipt  of an  Assignment  and  Acceptance  executed  by an
assigning  Lender and an Assignee  (and,  in the case of an Assignee that is not
then a Lender or an affiliate  thereof or a Person under common  management with
such Lender,  by the Borrower,  the  Administrative  Agent, the Arranger and the
Issuing  Lender)  together  with  payment  to  the  Administrative  Agent  of  a
registration and processing fee of $2,000 (except that no such  registration and
processing  fee shall be payable (y) in connection  with an assignment by Lehman
or (z) in the case of an Assignee  which is already a Lender or is an  affiliate
of  a  Lender  or  a  Person  under  common  management  with  a  Lender),   the
Administrative  Agent shall (i) promptly  accept such  Assignment and Acceptance
and  (ii)  on  the  effective  date  determined   pursuant  thereto  record  the
information contained therein in the Register and give notice of such acceptance
and  recordation to the Lenders and the Borrower.  On or prior to such effective
date, the Borrower, at its own expense, upon request,  shall execute and deliver
to the  Administrative  Agent (in exchange for the Revolving  Credit Note and/or
Term Note, as the case may be, of the assigning  Lender) a new Revolving  Credit
Note and/or Term Note,  as the case may be, to the order of such  Assignee in an
amount equal to the Revolving  Credit  Commitment  and/or Term Loan, as the case
may be, assumed by it pursuant to such  Assignment  and  Acceptance  and, if the
assigning Lender has retained a Revolving Credit Commitment and/or Term Loan, as
the case may be, upon request,  a new Revolving Credit Note and/or Term Note, as
the case may be, to the order of the assigning  Lender in an amount equal to the
Revolving Credit Commitment and/or Term Loan, as the case may be, retained by it
hereunder. Such new Notes shall be dated the Closing Date and shall otherwise be
in the form of the Note replaced thereby.

     (g) The Borrower  authorizes  each Lender to disclose to any Participant or
Assignee  (each,  a  "Transferee")  and any  prospective  Transferee any and all
financial  information in such Lender's  possession  concerning the Borrower and
its  Affiliates  which has been  delivered to such Lender by or on behalf of the
Borrower  pursuant to this  Agreement or which has been delivered to such Lender
by or on  behalf  of the  Borrower  in  connection  with  such  Lender's  credit
evaluation of the Borrower and its Affiliates  prior to becoming a party to this
Agreement.  (h) Nothing  herein  shall  prohibit or restrict any Lender from (i)
pledging or assigning any Note to any Federal  Reserve Bank in  accordance  with
applicable  law or (ii) with the prior consent of the  Administrative  Agent and
the Borrower (which, in each case, shall not be unreasonably withheld or delayed
or conditioned),  pledging its rights in connection with any Loan or Note to any
other Person.

     10.7 Adjustments;  Set-off. (a) If any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of its Loans or the Reimbursement
Obligations  owing to it, or  interest  thereon,  or receive any  collateral  in
respect  thereof  then due and  owing to such  Lender  (whether  voluntarily  or
involuntarily,  by  set-off,  pursuant  to events or  proceedings  of the nature
referred to in Section 8(f), or  otherwise),  in a greater  proportion  than any
such payment to or collateral  received by any other Lender,  if any, in respect
of such other Lender's Loans or the Reimbursement Obligations then due and owing
to such other Lender, or interest thereon, such Benefitted Lender shall purchase
for cash  from the other  Lenders a  participating  (or,  at the  option of such
Lender,  a direct)  interest in such  portion of each such other  Lender's  Loan
and/or of the  Reimbursement  Obligations  owing to each such other  Lender,  or
shall  provide such other Lenders with the benefits of any such  collateral,  or
the proceeds  thereof,  as shall be necessary to cause such Benefitted Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders;  provided that if all or any portion of such excess payment
or benefits is thereafter  recovered from such Benefitted Lender,  such purchase
shall be rescinded,  and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

     (b) In addition to any rights and remedies of the Lenders  provided by law,
each Lender shall have the right, without prior notice to the Borrower, any such
notice  being  expressly  waived by the  Borrower  to the  extent  permitted  by
applicable  law,  upon any  amount  becoming  due and  payable  by the  Borrower
hereunder or under the Notes (whether at the stated maturity, by acceleration or
otherwise) to set off and  appropriate and apply against such amount any and all
deposits  (general or special,  time or demand,  provisional  or final),  in any
currency,  and any other credits,  indebtedness or claims,  in any currency,  in
each case  whether  direct or  indirect,  absolute  or  contingent,  matured  or
unmatured,  at any time  held or owing by such  Lender  or any  branch or agency
thereof to or for the credit or the account of the Borrower.  Each Lender agrees
promptly  to notify the  Borrower  and the  Administrative  Agent after any such
setoff and  application  made by such Lender,  provided that the failure to give
such notice shall not affect the validity of such setoff and application.

     10.8  Counterparts.  This  Agreement  may be executed by one or more of the
parties to this Agreement on any number of separate  counterparts  (including by
telecopy),  and all of said  counterparts  taken  together  shall be  deemed  to
constitute  one and the same  instrument.  A set of the copies of this Agreement
signed  by  all  the  parties   shall  be  lodged  with  the  Borrower  and  the
Administrative Agent.

     10.9  Severability.  Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other  jurisdiction.  10.10  Integration.  This  Agreement  and the  other  Loan
Documents represent the agreement of the Borrower, the Administrative Agent, the
Arranger and the Lenders with respect to the subject  matter  hereof,  and there
are  no  promises,   undertakings,   representations   or   warranties   by  the
Administrative  Agent,  the  Arranger or any Lender  relative to subject  matter
hereof  not  expressly  set forth or  referred  to  herein or in the other  Loan
Documents.

     10.11  GOVERNING  LAW.  THIS  AGREEMENT  AND THE NOTES AND THE  RIGHTS  AND
OBLIGATIONS  OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED
BY, AND CONSTRUED AND  INTERPRETED  IN ACCORDANCE  WITH, THE LAW OF THE STATE OF
NEW YORK.

     10.12 Submission To Jurisdiction;  Waivers. The Borrower hereby irrevocably
and unconditionally:

     (a) submits for itself and its property in any legal  action or  proceeding
relating to this  Agreement and the other Loan Documents to which it is a party,
or for recognition and  enforcement of any judgment in respect  thereof,  to the
non-exclusive  general  jurisdiction of the Courts of the State of New York, the
courts of the United States for the Southern District of New York, and appellate
courts from any thereof;

     (b)  consents  that any such  action or  proceeding  may be brought in such
courts and waives any objection  that it may now or hereafter  have to the venue
of any such  action  or  proceeding  in any such  court or that  such  action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

     (c) agrees that service of process in any such action or proceeding  may be
effected  by mailing a copy  thereof by  registered  or  certified  mail (or any
substantially  similar form of mail),  postage  prepaid,  to the Borrower at its
address  set  forth in  Section  10.2 or at such  other  address  of  which  the
Administrative Agent shall have been notified pursuant thereto;

     (d) agrees that nothing  herein shall affect the right to effect service of
process in any other manner  permitted by law or shall limit the right to sue in
any other jurisdiction; and

     (e) waives,  to the maximum  extent not prohibited by law, any right it may
have to claim or recover in any legal action or  proceeding  referred to in this
Section 10.12 any special, exemplary, punitive or consequential damages.

     10.13 Acknowledgements. The Borrower hereby acknowledges that:

     (a) it has been  advised  by  counsel  in the  negotiation,  execution  and
delivery of this Agreement and the other Loan Documents;

     (b) neither any Agent nor any Lender has any fiduciary relationship with or
duty to the Borrower  arising out of or in connection with this Agreement or any
of the other  Loan  Documents,  and the  relationship  between  the  Agents  and
Lenders,  on one hand,  and the  Borrower,  on the  other  hand,  in  connection
herewith or therewith is solely that of debtor and creditor; and

     (c) no joint  venture is created  hereby or by the other Loan  Documents or
otherwise  exists by virtue of the  transactions  contemplated  hereby among the
Lenders or among the Borrower and the Lenders.

     10.14  WAIVERS OF JURY  TRIAL.  THE  BORROWER,  THE AGENTS AND THE  LENDERS
HEREBY IRREVOCABLY AND  UNCONDITIONALLY  WAIVE TRIAL BY JURY IN ANY LEGAL ACTION
OR PROCEEDING  RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY
COUNTERCLAIM THEREIN.

     10.15  Confidentiality.  Each of the Agents and each Lender  agrees to keep
confidential  all  non-public  information  provided  to it by  any  Loan  Party
pursuant  to  this   Agreement   that  is  designated  by  such  Loan  Party  as
confidential;  provided  that  nothing  herein  shall  prevent the Agents or any
Lender from  disclosing any such  information (a) to the Agents any other Lender
or any affiliate or investment  advisor of any Lender,  (b) to any Transferee or
prospective  Transferee  which  agrees to  comply  with the  provisions  of this
Section 10.15, (c) to the employees,  directors, agents, attorneys,  accountants
and other professional  advisors of such Lender or its affiliates,  (d) upon the
request or demand of any Governmental  Authority having  jurisdiction  over such
Agent  or such  Lender,  (e) in  response  to any  order  of any  court or other
Governmental  Authority  or  as  may  otherwise  be  required  pursuant  to  any
Requirement of Law, (f) if requested or required to do so in connection with any
litigation or similar  proceeding,  (g) which has been publicly  disclosed other
than in breach of this Section 10.15 or (h) in  connection  with the exercise of
any remedy hereunder or under any other Loan Document.

     10.16  Enforceability;  Usury.  In no event  shall  any  provision  of this
Agreement,  the  Notes,  or any other  instrument  evidencing  or  securing  the
indebtedness  of the  Borrower  hereunder  ever  obligate the Borrower to pay or
allow any Lender to collect  interest on the Notes or any other  indebtedness of
the Borrower  hereunder at a rate  greater  than the maximum  non-usurious  rate
permitted by applicable law (herein  referred to as the "Highest  Lawful Rate"),
or obligate  the  Borrower  to pay any taxes,  assessments,  charges,  insurance
premiums or other  amounts to the extent that such  payments,  when added to the
interest  payable on the Notes,  would be held to constitute  the payment by the
Borrower of interest at a rate  greater than the Highest  Lawful Rate;  and this
provision shall control over any provision to the contrary.

     Without limiting the generality of the foregoing, in the event the maturity
of all or any part of the principal  amount of the  indebtedness of the Borrower
hereunder  shall be accelerated  for any reason,  then such principal  amount so
accelerated  shall be credited  with any  interest  theretofore  paid thereon in
advance and remaining unearned at the time of such acceleration. If, pursuant to
the terms of this  Agreement or the Notes,  any funds are applied to the payment
of any  part  of  the  principal  amount  of the  indebtedness  of the  Borrower
hereunder  prior to the  maturity  thereof,  then (a) any  interest  which would
otherwise  thereafter accrue on the principal amount so paid by such application
shall be canceled,  and (b) the indebtedness of the Borrower hereunder remaining
unpaid after such application shall be credited with the amount of all interest,
if  any,  theretofore  collected  on  the  principal  amount  so  paid  by  such
application and remaining  unearned at the date of said application;  and if the
funds so applied shall be sufficient to pay in full all the  indebtedness of the
Borrower  hereunder,  then the Lenders shall refund to the Borrower all interest
theretofore  paid thereon in advance and remaining  unearned at the time of such
acceleration.  Regardless of any other provision in this Agreement, or in any of
the  written  evidences  of the  indebtedness  of the  Borrower  hereunder,  the
Borrower  shall  never  be  required  to  pay  any  unearned  interest  on  such
indebtedness or any portion thereof, and shall never be required to pay interest
thereon  at a rate in excess of the  Highest  Lawful  Rate  construed  by courts
having competent jurisdiction thereof. 13
