                                       13


         "LIBOR" means, for an Interest Period for a Borrowing of Eurodollar
Loans, (a) the LIBOR Index Rate for such Interest Period, if such rate is
available, and (b) if the LIBOR Index Rate cannot be determined, the
arithmetical average of the rates of interest per annum (rounded upwards, if
necessary, to the nearest one-sixteenth of one percent) at which deposits in
U.S. Dollars, in immediately available funds are offered to the Administrative
Agent at 11:00 a.m. (London, England time) two (2) Business Days before the
beginning of such Interest Period by major banks in the interbank eurodollar
market for delivery on the first day of and for a period equal to such Interest
Period in an amount equal or comparable to the principal amount of the smallest
Eurodollar Loan scheduled to be made by a Lender as part of such Borrowing.

         "LIBOR Index Rate" means, for any Interest Period, the rate per annum
(rounded upwards, if necessary, to the next higher one-sixteenth of one percent)
for deposits in U.S. Dollars for delivery on the first day of and for a period
equal to such Interest Period in an amount equal or comparable to the principal
amount of the smallest Eurodollar Loan scheduled to be made by a Lender as part
of such Borrowing, which appears on the Applicable Telerate Page as of 11:00
a.m. (London, England time) on the day two (2) Business Days before the
commencement of such Interest Period.

         "Applicable Telerate Page" means the display page designated as "Page
3750" on the Telerate Service (or such other pages as may replace any such page
on that service or such other service as may be nominated by the British
Bankers' Association as the information vendor for the purpose of displaying
British Bankers' Association Interest Settlement Rates for deposits in U.S.
Dollars).

         "Eurodollar Reserve Percentage" means for any Borrowing of Eurodollar
Loans from any Bank, the daily average for the applicable Interest Period of the
actual effective rate, expressed as a decimal, at which reserves (including,
without limitation, any supplemental, marginal and emergency reserves) are
maintained by such Bank during such Interest Period pursuant to Regulation D of
the Board of Governors of the Federal Reserve System (or any successor) on
"eurocurrency liabilities", as defined in such Board's Regulation D (or in
respect of any other category of liabilities that includes deposits by reference
to which the interest rate on Eurodollar Loans is determined or any category of
extensions of credit or other assets that include loans by non-United States
offices of any Bank to United States residents), subject to any amendments of
such reserve requirement by such Board or its successor, taking into account any
transitional adjustments thereto. For purposes of this definition, the
Eurodollar Loans shall be deemed to be "eurocurrency liabilities" as defined in
Regulation D without benefit or credit for any prorations, exemptions or offsets
under Regulation D.

     (c) Rate  Determinations.  The  Administrative  Agent shall  determine each
interest rate  applicable to  Obligations,  and a  determination  thereof by the
Administrative  Agent  shall be  conclusive  and  binding  except in the case of
manifest error.

     Section 2.4 Minimum  Borrowing  Amounts.  Each Borrowing of Base Rate Loans
and  Eurodollar  Loans shall be in an amount not less than (i) if such Borrowing
is comprised of Base Rate Loans,  $1,000,000 and integral  multiples of $500,000
in excess thereof,  and (ii) if such Borrowing is comprised of Eurodollar Loans,
$2,000,000 and integral multiples of $1,000,000 in excess thereof.

     Section  2.5  Manner of  Borrowing  Loans and  Designating  Interest  Rates
Applicable to Loans.  (a) Notice to the  Administrative  Agent. (a) The Borrower
shall give notice to the  Administrative  Agent by no later than 12:00 noon (New
York time) on the Effective  Date  specifying  the amount of Loans it desires to
borrow pursuant to this Agreement.  The initial Borrowing of Loans shall be Base
Rate  Loans.  Thereafter,  Borrower  may from  time to time  elect to  change or
continue  the type of  interest  rate  borne by each  Borrowing  or,  subject to
Section 2.4's minimum  amount  requirement  for each  outstanding  Borrowing,  a
portion thereof,  as follows:  (i) if such Borrowing is of Eurodollar  Loans, on
the last day of the Interest Period  applicable  thereto,  Borrower may continue
part or all of such  Borrowing  as  Eurodollar  Loans for an Interest  Period or
Interest Periods  specified by Borrower or convert part or all of such Borrowing
into Base Rate Loans,  and (ii) if such Borrowing is of Base Rate Loans,  on any
Business Day, Borrower may convert all or part of such Borrowing into Eurodollar
Loans for an Interest Period or Interest Periods specified by Borrower. Borrower
shall give all such notices  requesting  the  continuation  or  conversion  of a
Borrowing to the  Administrative  Agent by telephone or telecopy  (which  notice
shall be  irrevocable  once  given  and,  if by  telephone,  shall  be  promptly
confirmed in writing).  Notices of the continuation of a Borrowing of Eurodollar
Loans for an additional Interest Period or of the conversion of part or all of a
Borrowing  of  Eurodollar  Loans into Base Rate Loans or of Base Rate Loans into
Eurodollar  Loans  must be given by no later  than 12:00 noon (New York time) at
least three (3) Business Days before the date of the requested  continuation  or
conversion.  All such notices  concerning  the  continuation  or conversion of a
Borrowing  shall be  irrevocable  once given and shall  specify  the date of the
requested  continuation or conversion of a Borrowing  (which shall be a Business
Day),  the amount of the requested  Borrowing to be continued or converted,  the
type of Loans to comprise  such new,  continued or converted  Borrowing  and, if
such  Borrowing is to be  comprised of  Eurodollar  Loans,  the Interest  Period
applicable  thereto.  Borrower agrees that the Administrative  Agent may rely on
any such  telephonic  or  telecopy  notice  given by any person it in good faith
believes is an Authorized  Representative  without the necessity of  independent
investigation,  and in the event any such notice by telephone conflicts with any
written confirmation,  such telephonic notice shall govern if the Administrative
Agent has acted in  reliance  thereon.  There may be no more than six  different
Interest  Periods  in effect  at any one time,  provided  that for  purposes  of
determining  the number of Interest  Periods in effect at any one time, all Base
Rate Loans shall be deemed to have one and the same Interest Period.

     (b)  Notice to the  Banks.  The  Administrative  Agent  shall  give  prompt
telephonic or telecopy notice to each Bank of any notice from Borrower  received
pursuant to Section 2.5(a) above. The Administrative  Agent shall give notice to
Borrower and each Bank by like means of the  interest  rate  applicable  to each
Borrowing of Eurodollar Loans.

     (c) Borrower'  Failure to Notify.  Any  outstanding  Borrowing of Base Rate
Loans shall,  subject to Section 6.2 hereof,  automatically  be continued for an
additional  Interest Period on the last day of its then current  Interest Period
unless Borrower has notified the Administrative Agent within the period required
by Section  2.5(a) that it intends to convert such Borrowing into a Borrowing of
Eurodollar Loans or notifies the Administrative Agent within the period required
by Section 2.8(a) that it intends to prepay such Borrowing. If Borrower fails to
give notice  pursuant to Section 2.5(a) above of the  continuation or conversion
of any outstanding  principal  amount of a Borrowing of Eurodollar  Loans before
the last day of its then current  Interest  Period within the period required by
Section 2.5(a) and has not notified the  Administrative  Agent within


                                       15


the period  required by Section 2.8(a) that it intends to prepay such Borrowing,
such Borrowing  shall  automatically  be converted into a Borrowing of Base Rate
Loans,  subject to Section 6.2 hereof. The  Administrative  Agent shall promptly
notify the Banks of Borrower's failure to so give a notice under Section 2.5(a).

     (d)  Disbursement of Loans. Not later than 2:00 p.m. (New York time) on the
Effective Date, subject to Section 6 hereof,  each Bank shall make available its
Loan comprising part of the initial Borrowing in funds immediately  available at
the principal  office of the  Administrative  Agent in New York,  New York.  The
Administrative   Agent  shall  make   available   to   Borrower   Loans  at  the
Administrative  Agent's  principal  office in New York,  New York or such  other
office as the  Administrative  Agent has  previously  agreed in  writing to with
Borrower, in each case in the type of funds received by the Administrative Agent
from the Banks.

     (e)   Administrative   Agent   Reliance   on  Bank   Funding.   Unless  the
Administrative Agent shall have been notified by a Bank before the date on which
such  Bank is  scheduled  to make  payment  to the  Administrative  Agent of the
proceeds of a Loan (which notice shall be effective upon receipt) that such Bank
does not intend to make such payment,  the Administrative  Agent may assume that
such Bank has made such  payment  when due and the  Administrative  Agent may in
reliance upon such  assumption  (but shall not be required to) make available to
Borrower  the  proceeds of the Loan to be made by such Bank and, if any Bank has
not in fact made such payment to the  Administrative  Agent, such Bank shall, on
demand,  pay to the  Administrative  Agent the amount made available to Borrower
attributable to such Bank together with interest  thereon in respect of each day
during the period  commencing  on the date such  amount  was made  available  to
Borrower  and ending on (but  excluding)  the date such Bank pays such amount to
the  Administrative  Agent  at a rate per  annum  equal to (i) from the date the
related  payment  was  made by the  Administrative  Agent  to the  date  two (2)
Business  Days after  payment by such Bank is due  hereunder,  the Federal Funds
Rate for each such day and (ii) from the date two (2)  Business  Days  after the
date such payment is due from such Bank to the date such payment is made by such
Bank,  the Base Rate in effect for each such day. If such amount is not received
from such Bank by the  Administrative  Agent  immediately upon demand,  Borrower
will,  on demand,  repay to the  Administrative  Agent the  proceeds of the Loan
attributable to such Bank with interest thereon at a rate per annum equal to the
interest rate applicable to the relevant Loan.

     Section 2.6 Interest Periods.  As provided in Section 2.5(a) hereof, at the
time of each request of a Borrowing of Eurodollar  Loans,  Borrower shall select
an Interest  Period  applicable to such Loans from among the available  options.
The term "Interest  Period" means the period  commencing on the date a Borrowing
of Loans is advanced, continued, or created by conversion and ending: (a) in the
case of Base Rate Loans,  on the last  Business Day of the  calendar  quarter in
which such Borrowing is advanced, continued, or created by conversion (or on the
last day of the following  calendar quarter if such Loan is advanced,  continued
or created by conversion on the last  Business Day of a calendar  quarter),  and
(b) in the case of Eurodollar Loans, 1, 2, 3, or 6 months thereafter;  provided,
however, that:

          (a) any  Interest  Period  for a  Borrowing  of Base Rate  Loans  that
     otherwise would end after the Termination Date shall end on the Termination
     Date;

                                       16



          (b) for any Borrowing of Eurodollar Loans,  Borrower may not select an
     Interest Period that extends beyond the Termination Date;

          (c) whenever the last day of any Interest  Period would otherwise be a
     day that is not a Business Day, the last day of such Interest  Period shall
     be extended to the next  succeeding  Business Day,  provided  that, if such
     extension would cause the last day of an Interest Period for a Borrowing of
     Eurodollar Loans to occur in the following  calendar month, the last day of
     such Interest Period shall be the immediately preceding Business Day; and

          (d) for purposes of determining an Interest  Period for a Borrowing of
     Eurodollar  Loans, a month means a period starting on one day in a calendar
     month and ending on the numerically  corresponding day in the next calendar
     month; provided, however, that if there is no numerically corresponding day
     in the  month  in which  such an  Interest  Period  is to end or if such an
     Interest Period begins on the last Business Day of a calendar  month,  then
     such  Interest  Period  shall end on the last  Business Day of the calendar
     month in which such Interest Period is to end.

     Section 2.7 Maturity of Loans.  Unless an earlier  maturity is provided for
hereunder  (whether by  acceleration or otherwise),  all Obligations  (including
principal and interest on all outstanding Loans) shall mature and become due and
payable by Borrower on the Termination Date.

     Section 2.8  Prepayments.  (a) (a) Borrower may prepay  without  premium or
penalty and in whole or in part (but, if in part, then (i) in an amount not less
than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii)
in an amount such that the minimum amount  required for a Borrowing  pursuant to
Section 2.4 hereof remains  outstanding)  any Borrowing of Eurodollar Loans upon
three (3) Business Days' prior irrevocable  notice to the  Administrative  Agent
or, in the case of a Borrowing of Base Rate Loans,  irrevocable notice delivered
to the Administrative Agent no later than 12:00 noon (New York time) on the date
of prepayment, such prepayment to be made by the payment of the principal amount
to be prepaid and accrued interest thereon to the date fixed for prepayment.  In
the case of Eurodollar  Loans,  any amounts owing under Section 2.11 hereof as a
result of such prepayment shall be paid  contemporaneously with such prepayment.
The  Administrative  Agent will promptly advise each Bank of any such prepayment
notice it  receives  from  Borrower.  Any  amount  paid or  prepaid  before  the
Termination Date may not be borrowed again.

     Section 2.9 Default  Rate.  If any payment of  principal or interest on any
Loan,  or  payment of any other  Obligation,  is not made when due  (whether  by
acceleration or otherwise),  such principal,  interest or other Obligation shall
bear  interest  (computed  on the  basis of a year of 360 days and  actual  days
elapsed or, if based on the rate  described in clause (i) of the  definition  of
Base Rate,  on the basis of a year of 365 or 366 days,  as  applicable,  and the
actual  number of days elapsed) from the date such payment was due until paid in
full, payable on demand, at a rate per annum equal to:

          (a)  for  any  Obligation  other  than a  Eurodollar  Loan  (including
     principal  and  interest  relating  to Base  Rate  Loans  and  interest  on
     Eurodollar  Loans),  the sum of two


                                       17


percent (2%) plus the Applicable Margin plus the Base Rate from time to time in
effect; and

          (b) for the principal of any  Eurodollar  Loan, the sum of two percent
     (2%)  plus the  rate of  interest  in  effect  thereon  at the time of such
     default  until  the end of the  Interest  Period  applicable  thereto  and,
     thereafter,  at a rate per annum equal to the sum of two percent  (2%) plus
     the Applicable Margin plus the Base Rate from time to time in effect.

     Section  2.10 The Notes.  (a) The Loans made to Borrower by each Bank shall
be evidenced by a single  promissory note of Borrower issued to such Bank in the
form of Exhibit A hereto.  Each such promissory note is hereinafter  referred to
as a "Note"  and  collectively  such  promissory  notes are  referred  to as the
"Notes."

     (a) Each Bank shall record on its books and records or on a schedule to its
Note the  amount of each Loan  advanced,  continued,  or  converted  by it,  all
payments of principal and interest and the  principal  balance from time to time
outstanding  thereon,  the type of such Loan, and, for any Eurodollar  Loan, the
Interest  Period and the interest rate applicable  thereto.  The record thereof,
whether  shown on such books and records of a Bank or on a schedule to any Note,
shall be prima facie evidence of the same; provided,  however,  that the failure
of any Bank to record any of the foregoing or any error in any such record shall
not limit or otherwise affect the obligation of Borrower to repay all Loans made
hereunder together with accrued interest thereon. At the request of any Bank and
upon such Bank  tendering to Borrower the Note to be  replaced,  Borrower  shall
furnish a new Note to such Bank to replace  any  outstanding  Note,  and at such
time the first  notation  appearing  on a schedule  on the  reverse  side of, or
attached to, such Note shall set forth the aggregate  unpaid principal amount of
all Loans, if any, then outstanding thereon.

     Section 2.11 Funding  Indemnity.  If any Bank shall incur any loss, cost or
expense  (including,  without  limitation,  any loss, cost or expense (excluding
loss of  margin)  incurred  by reason of the  liquidation  or  re-employment  of
deposits or other funds acquired by such Bank to fund or maintain any Eurodollar
Loan or the relending or reinvesting of such deposits or amounts paid or prepaid
to such Bank) as a result of:

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

          (b) any  failure  (because  of a  failure  to meet the  conditions  of
     Section 6 or  otherwise)  by Borrower  to borrow or  continue a  Eurodollar
     Loan,  or to convert a Base Rate Loan into a Eurodollar  Loan,  on the date
     specified  in a notice  given  pursuant  to Section  2.5(a) or  established
     pursuant to Section 2.5(c) hereof,

          (c) any  failure by  Borrower  to make any  payment or  prepayment  of
     principal  on any  Eurodollar  Loan when due  (whether by  acceleration  or
     otherwise), or

          (d) any  acceleration of the maturity of a Eurodollar Loan as a result
     of the occurrence of any Event of Default hereunder,  then, upon the demand
     of such Bank, Borrower shall pay to such Bank such amount as will reimburse
     such Bank for such loss,  cost or  expense.  If any Bank makes such a claim
     for  compensation,  it  shall  provide  to

                                       18



     Borrower,  with a copy to the Administrative  Agent, a certificate executed
     by an officer of such Bank setting  forth the amount of such loss,  cost or
     expense in reasonable detail (including an explanation of the basis for and
     the  computation  of such loss,  cost or expense) and the amounts  shown on
     such certificate if reasonably  calculated shall be prima facie evidence of
     the amount of such loss, cost or expense.


     SECTION 3 FEES.

     Section 3.1 Fees.

     (a)  Administrative  Agent Fees.  Borrower shall pay to the  Administrative
Agent, for the  Administrative  Agent's sole account,  the fees agreed to in the
Fee Letter, which fees shall be fully earned and non-refundable once paid.

     SECTION 4 PLACE AND APPLICATION OF PAYMENTS.

     Section 4.1 Place and Application of Payments. All payments of principal of
and  interest  on the  Loans,  and of all other  Obligations  and other  amounts
payable by  Borrower  under the Credit  Documents,  shall be made by Borrower in
U.S.  Dollars to the  Administrative  Agent by no later than 2:00 p.m. (New York
time) on the due date  thereof  at the  principal  office of the  Administrative
Agent in New York,  New York pursuant to the payment  instructions  set forth on
Part A of Schedule 4 hereof (or such other location in the, United States as the
Administrative Agent may designate to Borrower) for the benefit of the Person or
Persons entitled thereto.  Any payments received after such time shall be deemed
to have been received by the Administrative  Agent on the next Business Day. All
such payments  shall be made free and clear of, and without  deduction  for, any
set-off,  defense,  counterclaim,  levy,  or any other  deduction of any kind in
immediately  available funds at the place of payment. The Administrative  Agent,
will promptly  thereafter  cause to be  distributed  like funds  relating to the
payment of  principal  or interest on Loans or  applicable  fees  ratably to the
Banks and like funds  relating to the payment of any other amount payable to any
Person to such Person,  in each case to be applied in accordance  with the terms
of this Agreement.

     SECTION 5 REPRESENTATIONS AND WARRANTIES.

     The Borrower hereby  represents and warrants to each Bank as to itself and,
where the following representations and warranties apply to its Subsidiaries, as
to each Subsidiary of Borrower, as follows:

     Section  5.1  Corporate  Organization  and  Authority.   Borrower  is  duly
organized  and  existing in good  standing  under the laws of the state of South
Dakota; has all necessary corporate power to carry on its present business;  and
is duly licensed or qualified and in good standing in each jurisdiction in which
the nature of the business  transacted by it or the nature of the Property owned
or leased by it makes such licensing,  qualification or good standing  necessary
and in which the failure to be so licensed,  qualified or in good standing would
have a Material Adverse Effect.

                                       19


     Section  5.2  Subsidiaries.  Schedule  5.2 (as  updated  from  time to time
pursuant to Section 7.1) hereto  identifies  each  Subsidiary  of Borrower,  the
jurisdiction of incorporation,  the percentage of issued and outstanding  shares
of each class of its capital  stock owned by the Borrower  and its  Subsidiaries
and, if such percentage is not one hundred percent (100%) (excluding  directors'
qualifying  shares as  required  by law),  a  description  of each  class of its
authorized  capital  stock and the  number of shares of each  class  issued  and
outstanding.  Each Subsidiary is duly incorporated and existing in good standing
as a corporation  under the laws of the jurisdiction of its  incorporation,  has
all  necessary  corporate  power to carry on its present  business,  and is duly
licensed or qualified  and in good  standing in each  jurisdiction  in which the
nature of the business  transacted by it or the nature of the Property  owned or
leased by it makes such  licensing or  qualification  necessary and in which the
failure to be so licensed or qualified would have a Material Adverse Effect. All
of the issued and outstanding  shares of capital stock of each Subsidiary  owned
directly or indirectly by Borrower are validly issued and  outstanding and fully
paid and  nonassessable  except as set forth on Schedule  5.2  hereto.  All such
shares  owned by Borrower  are owned  beneficially,  and of record,  free of any
Lien, except as permitted in Section 7.9.

     Section 5.3 Corporate  Authority and Validity of Obligations.  Borrower has
full right and  authority  to enter  into this  Agreement  and the other  Credit
Documents to which it is a party, to make the borrowings herein provided for, to
issue its Notes in  evidence  thereof,  to apply (and to have  applied),  and to
perform  all of its  obligations  under the  Credit  Documents  to which it is a
party.  Each Credit  Document  to which it is a party has been duly  authorized,
executed and delivered by Borrower and constitutes valid and binding obligations
of  Borrower   enforceable  in  accordance  with  its  terms,   except  as  such
enforceability  may  be  limited  by  bankruptcy,  insolvency,   reorganization,
moratorium or similar laws  affecting the  enforceability  of creditors'  rights
generally and by equitable  principles of general  applicability  (regardless of
whether such  enforceability is considered in a proceeding in equity or at law).
No Credit Document,  nor the performance or observance by Borrower of any of the
matters or things therein provided for,  contravenes any provision of law or any
charter or by-law provision of Borrower or any material  Contractual  Obligation
of or  affecting  Borrower  or any of  Borrower's  Properties  or  results in or
requires  the creation or  imposition  of any Lien on any of the  Properties  or
revenues of Borrower.

     Section 5.4  Financial  Statements.  All  financial  statements  heretofore
delivered to the Banks showing historical performance of Borrower for Borrower's
fiscal  years  ending on or before  December  31,  2001,  have been  prepared in
accordance   generally  accepted  accounting   principles  applied  on  a  basis
consistent,  except as otherwise noted therein, with that of the previous fiscal
year.  The unaudited  financial  statements for the fiscal period ended June 30,
2002 have been prepared in accordance  generally accepted accounting  principles
applicable to interim financial statements applied on a basis consistent, except
as otherwise noted therein,  with the previous same fiscal period of Borrower in
the prior fiscal year  (subject to normal  year-end  adjustments).  Each of such
financial  statements  fairly  presents on a  consolidated  basis the  financial
condition  of  Borrower  and its  Subsidiaries  as of the dates  thereof and the
results  of  operations  for  the  periods  covered  thereby.  Borrower  and its
Subsidiaries have no material contingent  liabilities other than those disclosed
in such financial  statements  referred to in this Section 5.4 or in comments or
footnotes thereto, or in any report supplementary thereto,  heretofore furnished
to the Banks.  Since  December  31,  2001,  there has been no event or series

                                       20


of events which has resulted  in, or  reasonably could be expected to result in,
a Material Adverse Effect.

     Section 5.5 No Litigation;  No Labor Controversies.(a)  Except as set forth
on Schedule 5.5, there is no litigation or governmental  proceeding  pending, or
to the knowledge of Borrower,  threatened, against Borrower or any Subsidiary of
Borrower  in which  there is a  reasonable  possibility  of an adverse  decision
which, if adversely determined,  could (individually or in the aggregate) have a
Material Adverse Effect.

     (b) Except as set forth on Schedule 5.5,  there are no labor  controversies
pending or, to the best knowledge of Borrower,  threatened  against  Borrower or
any Subsidiary of Borrower which could (individually or in the aggregate) have a
Material Adverse Effect.

     Section  5.6 Taxes.  Borrower  and its  Subsidiaries  have filed all United
States federal tax returns,  and all other foreign,  state,  local and other tax
returns,  required  to be filed and have paid all  taxes  due  pursuant  to such
returns or pursuant to any assessment  received by Borrower or any Subsidiary of
Borrower,  except such taxes,  if any, as are being  contested in good faith and
for which  adequate  reserves have been  provided.  No notices of tax liens have
been filed and no claims are being  asserted  concerning  any such taxes,  which
liens or claims are  material to the  financial  condition of Borrower or any of
its Subsidiaries  (individually or in the aggregate).  The charges, accruals and
reserves on the books of Borrower  and its  Subsidiaries  for any taxes or other
governmental charges are adequate and in conformance with GAAP.

     Section  5.7  Approvals.  No  authorization,  consent,  approval,  license,
exemption,  filing or registration  with any court or  governmental  department,
agency or  instrumentality,  nor any approval or consent of the  stockholders of
Borrower or any Subsidiary of Borrower or from any other Person, is necessary to
the valid  execution,  delivery or  performance by Borrower or any Subsidiary of
Borrower of any Credit Document to which it is a party.

     Section  5.8 ERISA.  With  respect to each  Plan,  Borrower  and each other
member of the Controlled  Group has fulfilled its obligations  under the minimum
funding  standards of and is in  compliance  in all material  respects  with the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"),  and with
the Code to the extent  applicable  to it and has not incurred any  liability to
the Pension Benefit  Guaranty  Corporation  ("PBGC") or a Plan under Title IV of
ERISA other than a liability  to the PBGC for  premiums  under  Section  4007 of
ERISA.  Neither  Borrower  nor any  Subsidiary  of Borrower  has any  contingent
liabilities for any  post-retirement  benefits under a Welfare Plan,  other than
liability for continuation coverage described in Part 6 of Title I of ERISA.

     Section 5.9 Government  Regulation.  Neither Borrower nor any Subsidiary of
Borrower is an "investment company" within the meaning of the Investment Company
Act of 1940, as amended,  or a "registered  holding  company",  or a "Subsidiary
company" of a "registered  holding company",  or an "affiliate" of a "registered
holding company" or of a "Subsidiary company" of a "registered holding company",
within  the  meaning of the  Public  Utility  Holding  Company  Act of 1935,  as
amended.

     Section  5.10 Margin  Stock;  Use of  Proceeds.  Neither  Borrower  nor any
Subsidiary  of  Borrower  is  engaged  principally,  or as one  of  its  primary
activities, in the business of extending

                                       21


credit for the purpose of purchasing or carrying margin stock ("margin stock" to
have the same meaning herein as in Regulation U of the Board of Governors of the
Federal Reserve System).  The proceeds of the Loans are to be used solely (i) to
provide liquidity support for Borrower's  commercial paper program, (ii) to fund
Borrower's  working capital needs, and (iii) for general  corporate  purposes of
Borrower.  Borrower  will not use the  proceeds  of any  Loan in a  manner  that

Federal Reserve System.

     Section 5.11 Licenses and  Authorizations;  Compliance  with Laws.  (a) (a)
Borrower and each of its  Subsidiaries has all necessary  licenses,  permits and
governmental  authorizations  to own and operate its  Properties and to carry on
its business as currently  conducted and contemplated.  Borrower and each of its
Subsidiaries is in compliance with all applicable laws, regulations,  ordinances
and orders of any governmental or judicial  authorities except for any such law,
regulation, ordinance or order which, the failure to comply therewith, could not
reasonably expected to have a Material Adverse Effect.

     (b) In the  ordinary  course  of its  business,  Borrower  and  each of its
Subsidiaries conduct an ongoing review of the effect of Environmental and Health
Laws on the  Properties  and all  aspects  of the  business  and  operations  of
Borrower and its  Subsidiaries  in the course of which such Borrower  identifies
and evaluates associated  liabilities and costs (including,  without limitation,
any  capital or  operating  expenditures  required  for  clean-up  or closure of
Properties  currently  or  previously  owned or used,  any capital or  operating
expenditures  required to achieve or maintain  compliance with standards imposed
by law and any  actual or  potential  liabilities  to third  parties,  including
employees or governmental entities, and any related costs and expenses).  On the
basis of this review,  Borrower has reasonably  concluded that Environmental and
Health Laws are unlikely to have any Material Adverse Effect.

     (c) Except as set forth on Schedule  5.11 (as amended  from time to time in
accordance with the provisions hereof),  neither the Borrower nor any Subsidiary
of Borrower  has given,  nor is it required to give,  nor has it  received,  any
notice, letter, citation, order, warning, complaint, inquiry, claim or demand to
or from any governmental entity or in connection with any court proceeding which
could  reasonably have a Material  Adverse Effect claiming that: (i) Borrower or
any  Subsidiary  of  Borrower  has  violated,   or  is  about  to  violate,  any
Environmental  and Health  Law;  (ii)  there has been a  release,  or there is a
threat  of  release,  of  Hazardous  Materials  from  Borrower's  or  any of its
Subsidiary's Property, facilities,  equipment or vehicles; (iii) Borrower or any
of its  Subsidiary  may be or is liable,  in whole or in part,  for the costs of
cleaning up, remediating or responding to a release of Hazardous  Materials;  or
(iv) any of Borrower's or any of its Subsidiary's Property or assets are subject
to a Lien in  favor  of any  governmental  entity  for any  liability,  costs or
damages,  under any Environmental and Health Law arising from, or costs incurred
by such governmental entity in response to, a release of a Hazardous Materials.

     Section 5.12 Ownership of Property;  Liens. Borrower and each Subsidiary of
Borrower has good title to or valid  leasehold  interests  in all its  Property.
None of Borrower's or any Subsidiary's  Property is subject to any Lien,  except
as permitted in Section 7.9.

     Section  5.13  No  Burdensome  Restrictions;  Compliance  with  Agreements.
Neither  Borrower nor any  Subsidiary of Borrower is (a) party or subject to any
law,   regulation,   rule  or

                                       22


order, or any Contractual  Obligation,  that  (individually or in the aggregate)
materially adversely affects the business, operations,  Property or financial or
other  condition  of  Borrower  and  its  Subsidiaries  (individually  or in the
aggregate) or (b) in default in the  performance,  observance or  fulfillment of
any of the  obligations,  covenants or conditions  contained in any agreement to
which it is a party (including any Contractual Obligation),  which default could
materially adversely affects the business, operations,  Property or financial or
other  condition  of  Borrower  and  its  Subsidiaries  (individually  or in the
aggregate).

Borrower  to  the  Administrative  Agent  or  any  Bank  for  purposes  of or in
connection with the Credit Documents or any transaction contemplated thereby is,
and all such information  hereafter  furnished by Borrower to the Administrative
Agent or any Bank will be, true and  accurate in all  material  respects and not
misleading.

in  reasonably  good repair,  working  order and condition and will from time to

and  betterments  thereto  so that at all  times  such  plants,  Properties  and
equipment shall be reasonably preserved and maintained,  and Borrower will cause

provided,  however, that nothing in this Section 7.2 shall prevent Borrower or a
Subsidiary of Borrower from  discontinuing  the operation or  maintenance of any
such Properties if such  discontinuance is not  disadvantageous  to the Banks or
the holders of the Notes,  does not materially impair the operations of Borrower
or any Subsidiary of Borrower and is, in the judgment of Borrower,  desirable in
the conduct of its business or the business of its Subsidiaries.

     Section 7.3 Taxes.  Borrower  will duly pay and  discharge,  and will cause

(as defined in ERISA)  affecting a Plan,  other than any such event of which the

     respects in accordance  with GAAP the  consolidated  financial  position of
     Borrower and its  Subsidiaries  as of the close of such fiscal year and the
     results of their  operations  and cash flows for the fiscal year then ended
     and that an examination of such accounts in connection  with such financial
     statements  has been made in accordance  with generally  accepted  auditing
     standards and,  accordingly,  such  examination  included such tests of the

     report to each Bank.  Together  with such  information  the Borrower  shall
     provide to each Bank such consolidating information as may be necessary for
     the Banks to determine the Borrower's compliance with Section 7.17 hereof;

          (ii) within 60 days after the end of each of the first three quarterly
     fiscal  periods of Borrower,  a  consolidated  unaudited  balance  sheet of
     Borrower and its  Subsidiaries,  and the related  statements  of income and
     statements  of  cash  flow,  as of the  close  of such  period,  all of the
     foregoing prepared by Borrower in reasonable detail in accordance with GAAP
     and certified by Borrower's chief financial officer or corporate controller
     as fairly  presenting  the financial  condition as at the dates thereof and
     the results of operations for the periods covered thereby, provided that if
     Borrower files a Form 10-Q for the applicable  quarterly  period,  and such
     quarterly  report  contains the  financial  statements  and  certifications
     described  above, the Borrower may satisfy the requirements of this Section
     7.6(a)(ii)  by  delivering  a copy of such  quarterly  report to each Bank.
     Together with such information the Borrower shall provide to each Bank such
     consolidating  information  as may be necessary  for the Banks to determine
     the Borrower's compliance with Section 7.17 hereof;

     statement  of the  accountants  who  certified  the  audit  report  thereby
     required  that in the course of their audit they have obtained no knowledge
     of any Default or Event of Default,  or, if such  accountants have obtained
     knowledge of any such Default or Event of Default,  they shall  disclose in
     such statement the nature and period of the existence thereof; and

          (iv) promptly after the sending or filing thereof, copies of all proxy
     statements,  financial  statements  and  reports  Borrower  or  any  of its

Event of Default and specifying the action,  if any, taken by Borrower to remedy
the same, (ii) the representations and warranties  contained in Section 5 hereof
are true and correct in all material respects as though made on the date of such
certificate (other than those made solely as of an earlier date, which need only
remain true as of such date), except as otherwise  described therein,  and (B) a

          (iv) of any  material  change  in the  information  set  forth  on the
     Schedules hereto; and

          (v) of the entering  into of any  Long-Term  Guaranties,  and Borrower
     shall  promptly  provide the  Administrative  Agent with a copy of any such

the  total  amount  of  rent  and  other  obligations  of the  Borrower  and its
Subsidiaries under such lease, when combined with all rent and other obligations
of Borrower and its Subsidiaries under all such leases, would exceed $30,000,000
in the  aggregate,  provided  that Borrower and its  Subsidiaries  may engage in
synthetic lease transactions so long as the Borrower's or such Subsidiary's,  as
applicable, obligations under such synthetic leases are included as Indebtedness

     Section 7.12 Mergers, Consolidations and Sales of Assets.

     other  Person  or  (ii)  sell,  lease  or  otherwise  dispose  of  all or a
     "substantial  part"  of  the  assets  of  Borrower  and  its  Subsidiaries;
     provided,  however,  that (w) the  foregoing  shall not  prohibit any sale,
     lease,  transfer or disposition to which the Required Banks have consented,
     such consent not to by unreasonably  withheld if (A) such  transaction does
     not  result in a  downgrade  of either  Borrower's  S&P  Rating or  Moody's
     Rating,   (B)  such  transaction  is  for  cash   consideration  (or  other
     consideration  acceptable to the Required Banks) in an amount not less than

     when combined with all other such  transactions,  would not have a Material
     Adverse Effect,  taken as a whole, (x) any Subsidiary of Borrower may merge
     or  consolidate  with or into or sell,  lease or otherwise  convey all or a
     substantial  part of its  assets to  Borrower  or any  Subsidiary  of which
     Borrower holds (directly or indirectly) at least the same percentage equity
     ownership;  provided  that in any such  merger or  consolidation  involving
     Borrower,  Borrower shall be the surviving or continuing  corporation,  (y)
     Borrower and its Subsidiaries may sell inventory,  reserves and electricity

          time of, or would occur as a result of, such  transaction.

assets during any fiscal year shall be deemed to be of a  "substantial  part" of
the  consolidated  assets of Borrower and its Subsidiaries if the net book value

     their Property,  or a proceeding  described in Section  8.1(f)(iv) shall be
     instituted   against  Borrower  or  any  Material   Subsidiary,   and  such
     appointment continues undischarged or such proceeding continues undismissed
     or unstayed for a period of sixty (60) days;

          (h) Borrower or any Material  Subsidiary shall fail within thirty (30)
     days to pay,  bond or  otherwise  discharge  any  judgment or order for the
     payment of money in excess of $10,000,000, which is not stayed on appeal or
     otherwise  being  appropriately  contested  in good faith in a manner  that
     stays execution thereon;

          (i) Borrower or any other member of the Controlled Group shall fail to
     pay when due an amount or amounts which it shall have become liable, to pay
     to the PBGC or to a Plan  under  Title IV of ERISA;  or notice of intent to
     terminate a Plan or Plans having aggregate  Unfunded Vested  Liabilities in
     excess of  $10,000,000  (collectively,  a "Material  Plan")  shall be filed
     under Title IV of ERISA by Borrower  or any  Subsidiary  of Borrower or any
     other  member  of the  Controlled  Group,  any  plan  administrator  or any
     combination of the foregoing; or the PBGC shall institute proceedings under
     Title IV of ERISA to  terminate  or to cause a trustee to be  appointed  to
     administer  any Material  Plan or a  proceeding  shall be  instituted  by a
     fiduciary of any Material Plan against  Borrower or any other member of the
     Controlled  Group to enforce  Section 515 or  4219(c)(5)  of ERISA and such
     proceeding   shall  not  have  been  dismissed   within  thirty  (30)  days
     thereafter; or a condition shall exist by reason of which the PBGC would be
     entitled to obtain a decree  adjudicating  that any  Material  Plan must be
     terminated;

          (j)  Borrower or any  Subsidiary  of Borrower or any Person  acting on
     behalf of Borrower,  a Subsidiary or any governmental  authority challenges
     the  validity  of  any  Credit   Document  or  Borrower's  or  one  of  its
     Subsidiary's  obligations thereunder or any Credit Document ceases to be in
     full force and effect or is  modified  other  than in  accordance  with the
     terms thereof and hereof;

          (k) a Change of Control Event shall have occurred; or

          (l) Borrower  shall for any reason  cease to be wholly  liable for the
     full amount of the Obligations.

     Section 8.2 Non-Bankruptcy  Defaults.  When any Event of Default other than
those described in subsections (f) or (g) of Section 8.1 hereof has occurred and
is continuing,  the  Administrative  Agent shall, if so directed by the Required
Banks,  by written notice to Borrower:  declare the principal of and the accrued
interest on all outstanding  Notes to be forthwith due and payable and thereupon
all outstanding  Notes,  including both principal and interest thereon,  and all
other Obligations, shall be and become immediately due and payable together with
all other amounts  payable under the Credit  Documents  without  further demand,
presentment,  protest or notice of any kind.  The  Administrative  Agent,  after
giving notice to Borrower  pursuant to Section 8.1(c) or this Section 8.2, shall
also promptly send a copy of such notice to the other Banks,  but the failure to
do so shall not impair or annul the effect of such notice.

     Section 8.3  Bankruptcy  Defaults.  When any Event of Default  described in
subsections (f) or (g) of Section 8.1 hereof has occurred,  then all outstanding
Notes,  including both interest and principal thereon, and all other Obligations

together  with all other  amounts  payable  under the Credit  Documents  without
presentment, demand, protest or notice of any kind.

     Section 8.4 [Intentionally Omitted](a).

and each Bank, and any other holder of any Note outstanding hereunder, all costs
and expenses  incurred or paid by the  Administrative  Agent or such Bank or any

counsel) and court costs,  in connection with (i) any amendment or waiver to the
Credit Documents requested by Borrower,  (ii) any Default or Event of Default by
Borrower hereunder, or (iii) the enforcement of any of the Credit Documents.

     SECTION 9 CHANGE IN CIRCUMSTANCES.

     Section 9.1 Change of Law.  Notwithstanding  any other  provisions  of this
Agreement  or any Note,  if at any time  after  the date  hereof  any  change in
applicable law or regulation or in the interpretation  thereof makes it unlawful
for any Bank to make or continue to maintain  Eurodollar Loans or to perform its
obligations as contemplated hereby, such Bank shall promptly give notice thereof
to Borrower and such Bank's  obligations  to make or maintain  Eurodollar  Loans
under this Agreement  shall  terminate  until it is no longer  unlawful for such
Bank to make or maintain  Eurodollar Loans.  Borrower shall prepay on demand the
outstanding  principal amount of any such affected  Eurodollar  Loans,  together
with all interest accrued thereon at a rate per annum equal to the interest rate
applicable  to such  Loan;  provided,  however,  subject to all of the terms and
conditions  of this  Agreement,  Borrower may then elect to borrow the principal
amount of the  affected  Eurodollar  Loans  from such Bank by means of Base Rate
Loans from such Bank,  which  Base Rate Loans  shall not be made  ratably by the
Banks but only from such affected Bank.

     Section 9.2  Unavailability  of  Deposits or  Inability  to  Ascertain,  or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any Borrowing of Eurodollar Loans:

          (a) the Administrative  Agent determines that deposits in U.S. Dollars
     (in the  applicable  amounts)  are not being  offered to major banks in the
     eurodollar  interbank market for such Interest Period, or that by reason of
     circumstances  affecting  the  interbank  eurodollar  market  adequate  and
     reasonable means do not exist for ascertaining the applicable LIBOR, or

          (b) Banks with  Percentages  aggregating at least 33% percent (33)% or
     more reasonably determine and so advise the Administrative Agent that LIBOR
     as reasonably  determined by the  Administrative  Agent will not adequately
     and fairly  reflect the cost to such Banks or Bank of funding  their or its
     Eurodollar Loans or Loan for such Interest Period,

then the Administrative Agent shall forthwith give notice thereof to Borrower
and the Banks, whereupon until the Administrative Agent notifies Borrower that
the circumstances giving rise to such suspension no longer exist, the
obligations of the Banks or of the relevant Bank to make Eurodollar Loans shall
be suspended.

                                       38



Section 9.3       Increased Cost and Reduced Return.

          (a) If, on or after the date hereof,  the  adoption of any  applicable
     law,  rule or  regulation,  or any  change  therein,  or any  change in the
     interpretation  or  administration  thereof by any governmental  authority,
     central  bank or  comparable  agency  charged  with the  interpretation  or
     administration  thereof,  or compliance by any Bank (or its Lending Office)
     with any request or directive  (whether or not having the force of law but,
     if not having the force of law,  compliance  with which is customary in the
     relevant  jurisdiction)  of any such authority,  central bank or comparable
     agency:

          (i) shall subject any Bank (or its Lending Office) to any tax, duty or
     other  charge  with  respect  to its  Eurodollar  Loans,  its  Notes or its
     obligation to make Eurodollar  Loans, or shall change the basis of taxation
     of  payments  to any Bank (or its Lending  Office) of the  principal  of or
     interest  on its  Eurodollar  Loans or any other  amounts  due  under  this
     Agreement  in respect of its  Eurodollar  Loans or its  obligation  to make
     Eurodollar  Loans (except for changes in the rate of tax on the overall net
     income  or  profits  of such  Bank or its  Lending  Office  imposed  by the
     jurisdiction  in which such Bank or its lending office is  incorporated  in
     which such Bank's principal executive office or Lending Office is located);
     or

          (ii) shall  impose,  modify or deem  applicable  any reserve,  special
     deposit or similar requirement  (including,  without  limitation,  any such
     requirement  imposed  by the  Board of  Governors  of the  Federal  Reserve
     System,  but  excluding  with  respect  to any  Eurodollar  Loans  any such
     requirement  included  in  an  applicable  Eurodollar  Reserve  Percentage)
     against assets of,  deposits with or for the account of, or credit extended
     by, any Bank (or its  Lending  Office) or shall  impose on any Bank (or its
     Lending Office) or on the interbank  market any other  condition  affecting
     its  Eurodollar  Loans,  its Notes,  or its  obligation to make  Eurodollar
     Loans;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Lending Office) of making or maintaining any Eurodollar Loan or to reduce
the amount of any sum received or receivable by such Bank (or its Lending
Office) under this Agreement or under its Notes with respect thereto, by an
amount deemed by such Bank to be material, then, within fifteen (15) days after
demand by such Bank (with a copy to the Administrative Agent), Borrower shall be
obligated to pay to such Bank such additional amount or amounts as will
compensate such Bank for such increased cost or reduction. In the event any law,
rule, regulation or interpretation described above is revoked, declared invalid
or inapplicable or is otherwise rescinded, and as a result thereof a Bank is
determined to be entitled to a refund from the applicable authority for any
amount or amounts which were paid or reimbursed by Borrower to such Bank
hereunder, such Bank shall refund such amount or amounts to Borrower without
interest.

     (b) If, after the date hereof, any Bank or the  Administrative  Agent shall
have  determined  that the adoption of any  applicable  law,  rule or regulation
regarding  capital  adequacy,   or  any  change  therein   (including,   without
limitation, any revision in the Final Risk-Based Capital Guidelines of the Board
of Governors of the Federal Reserve System (12 CFR Part 208,  Appendix A; 12 CFR
Part 225,  Appendix A) or of the Office of the  Comptroller  of the Currency (12
CFR Part 3, Appendix A), or in any other  applicable  capital  rules  heretofore
adopted  and  issued  by  any  governmental  authority),  or any  change  in the
interpretation or

                                       39



administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration  thereof, or compliance
by any Bank (or its  Lending  Office)  with any request or  directive  regarding
capital adequacy  (whether or not having the force of law but, if not having the
force of law, compliance with which is customary in the applicable jurisdiction)
of any such authority,  central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Bank's capital,  or on the capital
of any  corporation  controlling  such Bank, as a consequence of its obligations
hereunder to a level below that which such Bank could have achieved but for such
adoption,  change or compliance  (taking into consideration such Bank's policies
with  respect  to  capital  adequacy)  by an  amount  deemed  by such Bank to be
material,  then from time to time, within fifteen (15) days after demand by such
Bank (with a copy to the Administrative Agent),  Borrower shall pay to such Bank
such  additional  amount  or  amounts  as will  compensate  such  Bank  for such
reduction.

     (c) Each Bank that determines to seek  compensation  under this Section 9.3
shall notify Borrower and the  Administrative  Agent of the  circumstances  that
entitle  the Bank to such  compensation  pursuant  to this  Section 9.3 and will
designate a different  Lending  Office if such  designation  will avoid the need
for,  or reduce the  amount  of,  such  compensation  and will not,  in the sole
judgment of such Bank, be otherwise  disadvantageous to such Bank. A certificate
of any Bank claiming  compensation  under this Section 9.3 and setting forth the
additional  amount or amounts to be paid to it  hereunder  submitted to Borrower
and the  Administrative  Agent by such Bank in good faith  shall be prima  facie
evidence of the amount of such  compensation.  In determining such amount,  such
Bank may use any reasonable averaging and attribution methods.

     Section 9.4 Lending  Offices.  Each Bank may, at its option,  elect to make
its  Loans  hereunder  at the  branch,  office  or  affiliate  specified  on the
appropriate  signature  page  hereof or in the  assignment  agreement  which any
assignee  bank  executes  pursuant  to  Section  11.12  hereof  (each a "Lending
Office")  for each  type of Loan  available  hereunder  or at such  other of its
branches,  offices or affiliates as it may from time to time elect and designate
in a written notice to Borrower and the  Administrative  Agent,  so long as such
election does not increase  costs or other  amounts  payable by Borrower to such
Bank hereunder.

     Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding any
other  provision  of this  Agreement,  each Bank shall be  entitled  to fund and
maintain  its funding of all or any part of its Loans in any manner it sees fit,
it being  understood,  however,  that for the  purposes  of this  Agreement  all
determinations  hereunder  shall be made as if each Bank had actually funded and
maintained  each  Eurodollar  Loan  through  the  purchase  of  deposits  in the
eurodollar  interbank  market  having a maturity  corresponding  to such  Loan's
Interest  Period and bearing an interest  rate equal to LIBOR for such  Interest
Period.

     SECTION 10 THE AGENT.

     Section 10.1 Appointment and  Authorization of  Administrative  Agent. Each
Bank hereby appoints Credit Lyonnais New York Branch as the Administrative Agent
under the Credit  Documents and hereby  authorizes the  Administrative  Agent to
take such  action as  Administrative  Agent on its behalf and to  exercise  such
powers under the Credit Documents as are delegated to the  Administrative  Agent
by the terms  thereof,  together with such powers as are  reasonably  incidental
thereto.  The  Administrative  Agent  shall  have no duties or  responsibilities
except those expressly set forth in this Agreement and the Credit Documents. The
duties of the


                                       40



Administrative  Agent shall be  mechanical  and  administrative  in nature;  the
Administrative  Agent  shall not have by reason of this  Agreement  or any other
Credit  Document a fiduciary  relationship in respect of any Bank, the holder of
any Note or any other Person;  and nothing in this Agreement or any other Credit
Document,  expressed  or implied,  is intended to or shall be so construed as to
impose  upon  the  Administrative  Agent  any  obligations  in  respect  of this
Agreement or any other Credit  Document  except as expressly set forth herein or
therein.

     Section 10.2  Administrative  Agent and its Affiliates.  The Administrative
Agent shall have the same rights and powers under this  Agreement  and the other
Credit  Documents as any other Bank and may exercise or refrain from  exercising
the same as though it were not the Administrative  Agent, and the Administrative
Agent and its affiliates may accept  deposits from, lend money to, and generally
engage in any kind of business  with Borrower or any Affiliate of Borrower as if
it were not the Administrative Agent under the Credit Documents.

     Section 10.3 Action by Administrative  Agent. If the  Administrative  Agent
receives  from  Borrower  a written  notice of an Event of Default  pursuant  to
Section 7.6(c)(i) hereof, the  Administrative  Agent shall promptly give each of
the Banks written notice thereof.  The obligations of the  Administrative  Agent
under the Credit  Documents are only those expressly set forth therein.  Without
limiting the generality of the foregoing,  the Administrative Agent shall not be
required to take any action  hereunder  with  respect to any Default or Event of
Default,  except as  expressly  provided in  Sections  8.2 and 8.3. In no event,
however,  shall  the  Administrative  Agent be  required  to take any  action in
violation of applicable law or of any provision of any Credit Document,  and the
Administrative  Agent  shall in all  cases  be fully  justified  in  failing  or
refusing to act hereunder or under any other Credit  Document unless it shall be
first  indemnified to its reasonable  satisfaction  by the Banks against any and
all costs,  expense,  and  liability  which may be  incurred  by it by reason of
taking or continuing to take any such action. The Administrative  Agent shall be
entitled to assume that no Default or Event of Default exists unless notified to
the  contrary  in  writing  by a Bank or  Borrower.  In all cases in which  this
Agreement and the other Credit Documents do not require the Administrative Agent
to take certain actions,  the  Administrative  Agent shall be fully justified in
using its  discretion  in failing to take or in taking any action  hereunder and
thereunder.

     Section  10.4  Consultation  with  Experts.  The  Administrative  Agent may
consult with legal counsel,  independent  public  accountants  and other experts
selected  by it and shall not be liable  for any  action  taken or omitted to be
taken  by it in good  faith  in  accordance  with the  advice  of such  counsel,
accountants or experts.

     Section 10.5 Liability of Administrative  Agent;  Credit Decision.  Neither
the  Administrative  Agent  nor  any  of its  directors,  officers,  agents,  or
employees  shall be liable for any action taken or not taken by it in connection
with the Credit Documents (i) with the consent or at the request of the Required
Banks or (ii) in the absence of its own gross negligence or willful  misconduct.
Neither the Administrative Agent nor any of its directors,  officers,  agents or
employees shall be responsible  for or have any duty to ascertain,  inquire into
or verify (i) any statement,  warranty or representation made in connection with
this  Agreement,  any  other  Credit  Document  or any  Credit  Event;  (ii) the
performance  or  observance of any of the covenants or agreements of Borrower or
any other party  contained  herein or in any other  Credit  Document;  (iii) the
satisfaction  of any  condition  specified  in  Section  6  hereof;  or (iv) the
validity, effectiveness,  genuineness, enforceability,  perfection, value, worth
or  collectibility  hereof  or of


                                       41



any other  Credit  Document or of any other  documents  or writing  furnished in
connection  with any Credit  Document;  and the  Administrative  Agent  makes no
representation  of any  kind  or  character  with  respect  to any  such  matter
mentioned  in this  sentence.  The  Administrative  Agent may execute any of its
duties under any of the Credit Documents by or through  employees,  agents,  and
attorneys-in-fact  and shall not be  answerable to the Banks,  Borrower,  or any
other   Person  for  the   default  or   misconduct   of  any  such   agents  or
attorneys-in-fact  selected with reasonable care. The Administrative Agent shall
not  incur  any  liability  by  acting in  reliance  upon any  notice,  consent,
certificate,  other document or statement  (whether written or oral) believed by
it to be genuine or to be sent by the proper party or parties. In particular and
without limiting any of the foregoing,  the  Administrative  Agent shall have no
responsibility  for  confirming  the accuracy of any  Compliance  Certificate or
other  document or  instrument  received by it under the Credit  Documents.  The
Administrative Agent may treat the payee of any Note as the holder thereof until
written notice of transfer shall have been filed with the  Administrative  Agent
signed by such payee in form satisfactory to the Administrative Agent. Each Bank
acknowledges   that  it  has   independently   and   without   reliance  on  the
Administrative  Agent or any  other  Bank,  and  based  upon  such  information,
investigations  and  inquiries  as it deems  appropriate,  made  its own  credit
analysis  and  decision to extend  credit to Borrower in the manner set forth in
the Credit Documents. It shall be the responsibility of each Bank to keep itself
informed as to the  creditworthiness  of Borrower and any other relevant Person,
and the  Administrative  Agent shall have no  liability to any Bank with respect
thereto.

     Section 10.6 Indemnity.  The Banks shall ratably,  in accordance with their
respective  Percentages,  indemnify and hold the  Administrative  Agent, and its
directors,  officers,  employees,  agents and representatives  harmless from and
against any liabilities,  losses,  costs or expenses  suffered or incurred by it
under any Credit  Document or in connection with the  transactions  contemplated
thereby,  regardless  of when  asserted  or  arising,  except to the  extent the
Administrative  Agent is promptly reimbursed for the same by Borrower and except
to the  extent  that any event  giving  rise to a claim was  caused by the gross
negligence or willful  misconduct of the party  seeking to be  indemnified.  The
obligations  of the Banks under this Section 10.6 shall survive  termination  of
this Agreement.

     Section   10.7   Resignation   of   Administrative   Agent  and   Successor
Administrative  Agent. The Administrative Agent may resign at any time by giving
written notice thereof to the Banks and Borrower.  Upon any such  resignation of
the  Administrative  Agent, the Required Banks shall have the right to appoint a
successor  Administrative  Agent with the consent of  Borrower.  If no successor
Administrative  Agent shall have been so appointed by the  Required  Banks,  and
shall have accepted such appointment, within thirty (30) days after the retiring
Administrative  Agent's  giving  of  notice of  resignation,  then the  retiring
Administrative   Agent  may,  on  behalf  of  the  Banks,  appoint  a  successor
Administrative  Agent,  which shall be any Bank hereunder or any commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined  capital  and surplus of at least  $200,000,000.  Upon the
acceptance  of its  appointment  as the  Administrative  Agent  hereunder,  such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights and duties of the retiring or removed  Administrative Agent under
the Credit Documents,  and the retiring Administrative Agent shall be discharged
from its duties and obligations  thereunder.  After any retiring  Administrative
Agent's  resignation  hereunder as Administrative  Agent, the provisions of

                                       42


this Section 10 and all  protective  provisions  of the other  Credit  Documents
shall inure to its benefit as to any actions  taken or omitted to be taken by it
while it was Administrative Agent.

     SECTION 11 MISCELLANEOUS.

     Section 11.1 Withholding Taxes.

          (a) Payments Free of Withholding.  Subject to Section 11.1 (b) hereof,
     each payment by Borrower under this Agreement or the other Credit Documents
     shall be made  without  withholding  for or on  account  of any  present or
     future taxes (other than overall net income taxes on the recipient). If any
     such withholding is so required,  Borrower shall make the withholding,  pay
     the  amount  withheld  to the  appropriate  governmental  authority  before
     penalties attach thereto or interest accrues thereon and forthwith pay such
     additional  amount  as may be  necessary  to  ensure  that  the net  amount
     actually received by each Bank and the Administrative  Agent free and clear
     of such taxes (including such taxes on such additional  amount) is equal to
     the amount which that Bank or the Administrative Agent (as the case may be)
     would  have   received  had  such   withholding   not  been  made.  If  the
     Administrative  Agent or any Bank pays any  amount in  respect  of any such
     taxes,  penalties or interest  Borrower shall reimburse the  Administrative
     Agent or that Bank for that payment on demand in the currency in which such
     payment was made.  If Borrower  pay any such taxes,  penalties or interest,
     they  shall  deliver  official  tax  receipts  evidencing  that  payment or
     certified  copies  thereof  to the  Bank or  Administrative  Agent on whose
     account such withholding was made (with a copy to the Administrative  Agent
     if not the  recipient of the original) on or before the thirtieth day after
     payment. If any Bank or the Administrative Agent determines it has received
     or been granted a credit  against or relief or remission  for, or repayment
     of, any taxes paid or  payable  by it  because of any taxes,  penalties  or
     interest paid by Borrower and evidenced by such a tax receipt, such Bank or
     Administrative Agent shall, to the extent it can do so without prejudice to
     the retention of the amount of such credit, relief, remission or repayment,
     pay to Borrower such amount as such Bank or Administrative Agent determines
     is  attributable to such deduction or withholding and which will leave such
     Bank or  Administrative  Agent  (after such  payment) in no better or worse
     position  than it would have been in if Borrower  had not been  required to
     make  such  deduction  or  withholding.  Nothing  in this  Agreement  shall
     interfere  with the  right of each  Bank  and the  Administrative  Agent to
     arrange its tax affairs in whatever  manner it thinks fit nor  obligate any
     Bank or the  Administrative  Agent to disclose any information  relating to
     its tax affairs or any computations in connection with such taxes.

          (b) U.S.  Withholding Tax  Exemptions.  Each Bank that is not a United
     States person (as such term is defined in Section  7701(a)(30) of the Code)
     shall submit to Borrower and the Administrative Agent on or before the date
     of the initial Borrowing  hereunder two duly completed and signed copies of
     either Form W8BEN  (relating  to such Bank and  entitling  it to a complete
     exemption from withholding  under the Code on all amounts to be received by
     such Bank,  including fees, pursuant to the Credit Documents and the Loans)
     or Form  W8ECI  (relating  to all  amounts  to be  received  by such  Bank,
     including  fees,  pursuant  to the Credit  Documents  and the Loans) of the
     United States Internal Revenue  Service.  Thereafter and from time to time,
     each Bank  shall  submit to  Borrower  and the  Administrative  Agent  such
     additional  duly  completed


                                       43


     and  signed  copies  of one or the other of such  Forms (or such  successor
     forms as shall be adopted from time to time by the relevant  United  States
     taxing  authorities)  as may be (i)  requested  by  Borrower  in a  written
     notice, directly or through the Administrative Agent, to such Bank and (ii)
     required  under then current  United States law or  regulations to avoid or
     reduce  United  States  withholding  taxes on  payments  in  respect of all
     amounts to be received by such Bank, including fees, pursuant to the Credit
     Documents or the Loans.

          (c) Inability of Bank to Submit Forms.  If any Bank  determines,  as a
     result of any change in applicable  law,  regulation  or treaty,  or in any
     official application or interpretation thereof, that it is unable to submit
     to Borrower or Administrative  Agent any form or certificate that such Bank
     is obligated to submit  pursuant to subsection  (b) of this Section 11.1 or
     that  such  Bank is  required  to  withdraw  or  cancel  any  such  form or
     certificate  previously submitted or any such form or certificate otherwise
     becomes ineffective or inaccurate, such Bank shall promptly notify Borrower
     and Administrative Agent of such fact and the Bank shall to that extent not
     be obligated to provide any such form or  certificate  and will be entitled
     to withdraw or cancel any affected form or certificate, as applicable.

     Section  11.2 No Waiver of  Rights.  No delay or failure on the part of the
Administrative  Agent or any Bank or on the part of the holder or holders of any
Note in the  exercise  of any power or right  under any  Credit  Document  shall
operate as a waiver thereof,  nor as an  acquiescence in any default,  nor shall
any single or partial exercise thereof preclude any other or further exercise of
any  other  power  or  right,  and the  rights  and  remedies  hereunder  of the
Administrative  Agent,  the Banks and the  holder  or  holders  of any Notes are
cumulative  to, and not exclusive  of, any rights or remedies  which any of them
would otherwise have.

     Section 11.3  Non-Business  Day. If any payment of principal or interest on
any Loan or of any  other  Obligation  shall  fall  due on a day  which is not a
Business Day, interest or fees (as applicable) at the rate, if any, such Loan or
other Obligation bears for the period prior to maturity shall continue to accrue
on such  Obligation  from the stated due date thereof to and  including the next
succeeding Business Day, on which the same shall be payable.

     Section  11.4  Documentary  Taxes.  Borrower  agrees  that it will  pay any
documentary,  stamp or similar taxes payable in respect to any Credit  Document,
including  interest  and  penalties,  in the event any such taxes are  assessed,
irrespective  of when such  assessment  is made and whether or not any credit is
then in use or available hereunder.

     Section  11.5  Survival  of   Representations.   All   representations  and
warranties  made herein or in  certificates  given pursuant hereto shall survive
the execution and delivery of this Agreement and the other Credit Documents, and
shall  continue  in full force and effect  with  respect to the date as of which
they were made as long as any credit is in use or available hereunder.

     Section  11.6  Survival  of  Indemnities.  All  indemnities  and all  other
provisions  relative  to  reimbursement  to the Banks of amounts  sufficient  to
protect  the yield of the Banks with  respect to the Loans,  including,  but not
limited to,  Section 2.11,  Section 9.3 and Section 11.15 hereof,  shall survive
the termination of this Agreement and the other Credit Documents and the payment
of the Loans and all other Obligations.

                                       44



     Section  11.7  Set-Off.  (a) (a) In addition to any rights now or hereafter
granted  under  applicable  law and not by way of limitation of any such rights,
upon the  occurrence  of any Event of  Default,  each  Bank and each  subsequent
holder of any Note is hereby  authorized by Borrower at any time or from time to
time,  without notice to Borrower or to any other Person,  any such notice being
hereby expressly  waived, to set off and to appropriate and to apply any and all
deposits  (general or  special,  including,  but not  limited  to,  Indebtedness
evidenced by  certificates  of deposit,  whether  matured or  unmatured,  and in
whatever  currency  denominated) and any other  Indebtedness at any time held or
owing by that Bank or that subsequent holder to or for the credit or the account
of Borrower,  whether or not matured,  against and on account of the obligations
and  liabilities  of Borrower to that Bank or that  subsequent  holder under the
Credit  Documents,  including,  but not  limited to, all claims of any nature or
description arising out of or connected with the Credit Documents,  irrespective
of whether or not (a) that Bank or that  subsequent  holder  shall have made any
demand  hereunder or (b) the  principal of or the interest on the Loans or Notes
and other  amounts due hereunder  shall have become due and payable  pursuant to
Section 8 and although said obligations and liabilities,  or any of them, may be
contingent or unmatured.

     (b) Each Bank agrees with each other Bank a party  hereto that if such Bank
shall  receive  and retain any  payment,  whether by set-off or  application  of
deposit  balances  or  otherwise,  on any of the Loans in excess of its  ratable
share of payments on all such obligations  then  outstanding to the Banks,  then
such Bank shall purchase for cash at face value, but without  recourse,  ratably
from each of the other  Banks  such  amount of the Loans held by each such other
Banks (or  interest  therein) as shall be  necessary to cause such Bank to share
such excess payment ratably with all the other Banks; provided, however, that if
any such  purchase  is made by any  Bank,  and if such  excess  payment  or part
thereof is thereafter recovered from such purchasing Bank, the related purchases
from the other Banks shall be rescinded  ratably and the purchase price restored
as to the portion of such excess payment so recovered, but without interest.

     Section 11.8 Notices.  Except as otherwise  specified  herein,  all notices

                  Notices shall be sent to the applicable address set forth on
                  Part B of Schedule 4 hereto.

     Each such notice,  request or other communication shall be effective (i) if
given by facsimile,  when such facsimile is transmitted to the facsimile  number
specified  in  this  Section  11.8  or  on  the  signature  pages  hereof  and a
confirmation of receipt of such facsimile has been received by the sender,  (ii)
if given by courier, when delivered, (iii) if given by mail, three business days
after such  communication  is  deposited  in the mail,  registered  with  return
receipt  requested,  addressed as aforesaid or (iv) if given by any other means,
when  delivered at the addresses  specified in this Section 11.8;  provided that
any notice  given  pursuant  to Section 2 hereof  shall be  effective  only upon
receipt.

     Section 11.9 Counterparts.  This Agreement may be executed in any number of
counterpart   signature  pages,  and  by  the  different  parties  on  different
counterparts,  each of which when  executed  shall be deemed an original but all
such  counterparts  taken together shall constitute one and the same instrument.
Delivery of an executed  counterpart  via  facsimile  shall for all  purposes be
deemed as effective as delivery of an original counterpart.

     Section 11.10 Successors and Assigns.  This Agreement shall be binding upon
Borrower and its successors and assigns,  and shall inure to the benefit of each
of the Banks and the  benefit  of their  permitted  respective  successors,  and
assigns,  including any subsequent  holder of any Note.  Borrower may not assign
any of its  rights or  obligations  under any  Credit  Document  unless (i) such
assignation  occurs in connection with a merger or acquisition by Borrower which
is otherwise  permitted  under the terms of this  Agreement and the  appropriate
Credit  Document,  if  applicable  and (ii)  Borrower  obtains the prior written
consent  of all of the  Banks,  which  consent  shall be in form  and  substance
satisfactory to Administrative Agent.

     Section 11.11  Participants  and Note  Assignees.  Each Bank shall have the
right at its own cost to grant  participations  (to be  evidenced by one or more
agreements or certificates of

                                       46


participation) in the Loans made by such Bank at any time and from time to time,
and to assign its rights under such Loans or the Note evidencing such Loans to a
federal  reserve  bank;  provided that (i) no such  participation  or assignment
shall relieve any Bank of any of its obligations  under this Agreement,  (ii) no
such assignee or participant  shall have any rights under this Agreement  except
as provided in this Section 11.11, and (iii) the Administrative Agent shall have
no obligation or  responsibility  to such  participant or assignee,  except that
nothing  herein is  intended  to affect the rights of an  assignee  of a Note to
enforce the Note assigned. Any party to which such a participation or assignment
has been  granted  shall have the  benefits of Section 2.11 and Section 9.3, but
shall not be entitled to receive any greater  payment  under either such Section
than the Bank granting such participation would have been entitled to receive in
connection with the rights transferred. Any agreement pursuant to which any Bank
may grant  such a  participating  interest  shall  provide  that such Bank shall
retain the sole right and  responsibility to enforce the obligations of Borrower
hereunder,  including,  without limitation,  the right to approve any amendment,
modification  or waiver of any provision of this  Agreement;  provided that such
participation  agreement  may  provide  that  such  Bank  will not  agree to any
modification,  amendment or waiver of this  Agreement that would (A) forgive any
amount of or postpone  the date for payment of any  principal  of or interest on
any Loan or of any fee  payable  hereunder  in  which  such  participant  has an
interest or (B) reduce the stated  rate at which  interest or fees in which such
participant has an interest accrue hereunder.

     Section 11.12  Assignments by Banks.  Each Bank shall have the right at any
time,  with the  written  consent of  Administrative  Agent,  and,  prior to the
occurrence of a Default or Event of Default,  Borrower, which consents shall not
be unreasonably  withheld, to assign all or any part of its Note and outstanding
Loans to one or more  other  Persons;  provided  that such  assignment  is in an
amount of at least $5,000,000 or the entire  outstanding amount of Loans made by
such Bank,  and if such  assignment  is not for such Bank's  entire  outstanding
amount of Loans  then the  amount of  outstanding  Loans made by such Bank after
giving effect to such assignment shall not be less than $5,000,000; and provided
further that neither the consent of Borrower nor the Administrative  Agent shall
be required for any Bank to assign all or part of its Note and outstanding Loans
to any Affiliate of the assigning Bank. Each such assignment shall set forth the
assignees  address for notices to be given under  Section 11.8 hereof  hereunder
and its designated Lending Office pursuant to Section 9.4 hereof.  Upon any such
assignment,  delivery to the  Administrative  Agent of an executed  copy of such
assignment  agreement  and the forms  referred  to in Section  11.1  hereof,  if
applicable,  and the payment of a $3,500  recordation fee to the  Administrative
Agent,  the assignee shall become a Bank  hereunder,  all Loans it thereby holds
shall be governed by all the terms and  conditions  hereof and the Bank granting
such  assignment  shall have its rights in connection  therewith  reduced by the
amount of such assignment.

     Section  11.13  Amendments.  Any  provision of the Credit  Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by (a) Borrower,  (b) the Required Banks, and (c) if the rights or duties
of the  Administrative  Agent are affected thereby,  the  Administrative  Agent;
provided that:

          (i) no  amendment  or waiver  pursuant  to this  Section.  11.13 shall
     reduce  the  amount  of or  postpone  any  fixed  date for  payment  of any
     principal  of or  interest  on any Loan or of any fee or  other  Obligation
     payable hereunder without the consent of each Bank; and


                                       47



          (ii) no  amendment  or waiver  pursuant to this  Section  11.13 shall,
     unless signed by each Bank, change this Section 11.13, or the definition of
     Required  Banks,  or affect the number of Banks required to take any action
     under the Credit Documents.

     Anything in this Agreement to the contrary notwithstanding,  if at any time
when the  conditions  precedent  set  forth in  Section  6.2  hereof to any Loan
hereunder are satisfied,  any Bank shall fail to fulfill its obligations to make
such Loan (any such Bank, a "Defaulting Bank") then, for so long as such failure
shall continue,  the Defaulting Bank shall (unless Borrower,  the Administrative
Agent and the Required Banks  (determined  as if the Defaulting  Bank were not a
Bank hereunder)  shall otherwise  consent in writing) be deemed for all purposes
related to amendments,  modifications,  waivers or consents under this Agreement
(other than  amendments or waivers  referred to in clause (i) and (ii) above) to
have no Loans and shall not be treated as a Bank hereunder  when  performing the
computation  of the  Required  Banks.  To the  extent the  Administrative  Agent
receives any payments or other amounts for the account of a Defaulting Bank such
Defaulting Bank shall be deemed to have requested that the Administrative  Agent
use such payment or other amount to fulfill its obligations to make such Loan.

     Section 11.14  Headings.  Section  headings used in this  Agreement are for
reference only and shall not affect the construction of this Agreement.

     Section 11.15 Legal Fees, Other Costs and Indemnification.  Borrower agrees
to pay  all  reasonable  costs  and  expenses  of the  Administrative  Agent  in
connection  with  the  preparation  and  negotiation  of  the  Credit  Documents
(including past and future  reasonable  out-of-pocket  expenses  incurred by the
Administrative  Agent in connection  with the  syndication of the  transaction),
including without  limitation,  the reasonable fees and disbursements of counsel
to the Administrative Agent, in connection with the preparation and execution of
the Credit  Documents,  and any  amendment,  waiver or consent  related  hereto,
whether or not the transactions  contemplated  herein are consummated.  Borrower
further  agrees to indemnify  each Bank,  the  Administrative  Agent,  and their
respective  directors,  agents,  officers  and  employees,  against  all losses,
claims,  damages,  penalties,  judgments,  liabilities and expenses  (including,
without limitation,  all expenses of litigation or preparation therefor, whether
or not the indemnified Person is a party thereto) which any of them may incur or
reasonably pay arising out of or relating to any Credit Document  (including any
relating to a misrepresentation by Borrower under any Credit Document) or any of
the transactions  contemplated  thereby or the direct or indirect application or
proposed  application of the proceeds of any Loan,  other than those which arise
from  the  gross  negligence  or  willful   misconduct  of  the  party  claiming
indemnification.  Borrower,  upon demand by any of the Administrative Agent or a
Bank at any  time,  shall  reimburse  the  Administrative  Agent or Bank for any
reasonable  legal or other  expenses  (including  allocable fees and expenses of
in-house counsel) incurred in connection with investigating or defending against
any of the foregoing  except if the same is directly due to the gross negligence
or willful misconduct of the party to be indemnified, provided that with respect
to legal costs and expenses  incurred in connection  with the enforcement of the
Banks rights hereunder or any work-out or similar situation, Borrower shall only
be  obligated to pay the legal fees of the  Administrative  Agent and not of any
other Bank.

     Section 11.16 Entire Agreement.  The Credit Documents constitute the entire
understanding  of the parties thereto with respect to the subject matter thereof
and any prior or

                                       48



contemporaneous  agreements,  whether  written or oral, with respect thereto are
superseded thereby.

     Section 11.17  Construction.  The parties hereto acknowledge and agree that
neither this  Agreement nor the other Credit  Documents  shall be construed more
favorably  in favor of one than the other  based upon which  party  drafted  the
same, it being acknowledged that all parties hereto contributed substantially to
the negotiation of this Agreement and the other Credit Documents.

     Section 11.18 Governing Law. This Agreement and the other Credit Documents,
and the  rights  and  duties  of the  parties  hereto,  shall be  construed  and
determined in accordance with the internal laws of the State of New York.

     Section 11.19 SUBMISSION TO JURISDICTION;  WAIVER OF JURY TRIAL.  BORROWER,
ADMINISTRATIVE   AGENT  AND  EACH  BANK  HEREBY  SUBMITS  TO  THE   NONEXCLUSIVE
JURISDICTION  OF THE UNITED STATES  DISTRICT COURT FOR THE SOUTHERN  DISTRICT OF
NEW YORK AND OF ANY NEW YORK  STATE  COURT  SITTING  IN THE CITY OF NEW YORK FOR
PURPOSES OF ALL LEGAL PROCEEDINGS  ARISING OUT OF OR RELATING TO THIS AGREEMENT,
THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS  CONTEMPLATED  HEREBY OR THEREBY.
BORROWER,  ADMINISTRATIVE AGENT AND EACH BANK IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM
THAT  ANY  SUCH  PROCEEDING  BROUGHT  IN SUCH A COURT  HAS  BEEN  BROUGHT  IN AN
INCONVENIENT  FORUM.  BORROWER,   ADMINISTRATIVE  AGENT  AND  EACH  BANK  HEREBY
IRREVOCABLY  WAIVES  ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL  PROCEEDING
ARISING  OUT  OF  OR  RELATING  TO  ANY  CREDIT  DOCUMENT  OR  THE  TRANSACTIONS
CONTEMPLATED THEREBY.

     Section  11.20  Replacement  of  Bank.  Each  Bank  agrees  that,  upon the
occurrence of any event set forth in Sections 9.1, 9.3 and 11.1,  such Bank will
use  reasonable  efforts  to book and  maintain  its Loans  through a  different
Lending  Office or to transfer its Loans to an Affiliate  with the  objective of
avoiding  or  minimizing  the  consequences  of such event;  provided  that such
booking or transfer is not otherwise  disadvantageous to such Bank as determined
by such Bank in its sole and absolute discretion. If any Bank has demanded to be
paid additional  amounts pursuant to Sections 9.1, 9.3 and 11.1, and the payment
of such  additional  amounts are, and are likely to continue to be, more onerous
in the  reasonable  judgment of Borrower  than with  respect to the other Banks,
then  Borrower  shall  have the  right at any time when no  Default  or Event of
Default  shall have  occurred and be  continuing  to seek one or more  financial
institutions  which are not Affiliates of Borrower (each, a "Replacement  Bank")
to purchase with the written consent of the Administrative  Agent (which consent
shall not be (x) required if such proposed  Replacement  Bank is already a Bank,
or an  Affiliate  of a  Bank,  or (y)  unreasonably  delayed  or  withheld)  the
outstanding Loans of such Bank (the "Affected  Bank"),  and if Borrower locate a
Replacement Bank, the Affected Bank shall, upon

          i.   prior written notice to the Administrative Agent,


                                       49



          ii.  (i) payment to the  Affected  Bank of the  purchase  price agreed
               between it and the Replacement  Bank (or, failing such agreement,
               a  purchase  price in the  amount  of the  outstanding  principal
               amount of the Affected Bank's Loans and accrued  interest thereon
               to the date of payment) by the Replacement Bank plus (ii) payment
               by Borrower of all Obligations (other than principal and interest
               with respect to Loans) then due to the  Affected  Bank or accrued
               for its account hereunder or under any other Loan Document,

          iii. satisfaction of the provisions set forth in Section 11.12, and

          iv.  payment by Borrower to the Affected  Bank and the  Administrative
               Agent of all reasonable out-of-pocket expenses in connection with
               such  assignment and assumption  (including the  recordation  fee
               described in Section 11.12),

assign and delegate all its rights and obligations under this Agreement and any
other Credit Document to which it is a party (including its outstanding Loans)
to the Replacement Bank (such assignment to be made without recourse,
representation or warranty), and the Replacement Bank shall assume such rights
and obligations, whereupon the Replacement Bank shall in accordance with Section
11.12 become a party to each Credit Document to which the Affected Bank is a
party and shall have the rights and obligations of a Bank thereunder and the
Affected Bank shall be released from its obligations hereunder and each other
Credit Document to the extent of such assignment and delegation.

Section 11.21 Confidentiality. The Administrative Agent and the Banks shall hold
all non-public information provided to them by Borrower pursuant to or in
connection with this Agreement in accordance with their customary procedures for
handling confidential information of this nature, but may make disclosure to any
of their examiners, regulators, Affiliates, outside auditors, counsel and other
professional advisors in connection with this Agreement or any other Credit
Document or as reasonably required by any potential bona fide transferee,
participant or assignee, or in connection with the exercise of remedies under a
Credit Document, or to any direct or indirect contractual counterparty in swap
agreements or such contractual counterparty's professional advisor (so long as
such contractual counterparty or professional advisor to such contractual
counterparty agrees to be bound by the provisions of this Section 11.21), or to
any nationally recognized rating agency that requires access to information
about a Bank's investment portfolio in connection with ratings issued with
respect to such Bank, or as requested by any governmental agency or
representative thereof or pursuant to legal process; provided, however, that
unless specifically prohibited by applicable law or court order, the
Administrative Agent and each Bank shall use reasonable efforts to promptly
notify Borrower of any request by any governmental agency or representative
thereof (other than any such request in connection with an examination of the
financial condition of the Administrative Agent or such Bank by such
governmental agency) for disclosure of any such non-public information and,
where practicable, prior to disclosure of such information. Prior to any such
disclosure pursuant to this Section 11.21, the Administrative Agent and each
Bank shall require any such bona fide transferee, participant and assignee
receiving a disclosure of non-public information to agree, for the benefit of
Borrower, in writing to be bound by this Section 11.21; and to require such
Person

                                       50


to require any other Person to whom such Person discloses such non-public
information to be similarly bound by this Section 11.21.

                       LITIGATION AND LABOR CONTROVERSIES

Black Hills Harbor, LLC--City of Long Beach

         In June of 2000, the City of Long Beach, a municipal corporation in the
State of California, acting for the Port of Long Beach ("City"), brought an
action against Black Hills Harbor, LLC (formerly known as Indeck Harbor, LLC)
("Fund"), alleging breaches of a partnership interest purchase agreement dated
as of January 1, 1995 ("Agreement"), relating to the amount and timing of
certain contingent payments, if any, due the City resulting in claims by the
City in excess of $9 million. The court ordered that the disputes raised in
litigation must be resolved by arbitration in accordance with the terms of the
Agreement. Representatives of the City and the Fund engaged in mediation to
attempt to resolve the disputes involving a transportation tax for natural gas
delivered to a power facility located in Long Beach and owned by the Fund.
Because the parties were unable to reach resolution of the dispute, they have
pursued arbitration.

Grizzly Gulch Fire


         On June 29, 2002, a forest fire began near Deadwood, South Dakota.
Before being contained more than eight days later, the fire consumed over 10,000
acres of public and private land, mostly consisting of rugged forested areas.
The fire destroyed 7 homes, and approximately 15 outbuildings. There are no
reported personal injuries at this time. In addition, the fire burned to the
edge of the City of Deadwood, forcing the evacuation of the City of Deadwood,
and an adjacent City of Lead, South Dakota. These communities are active in the
tourist and gaming industries. Individuals were ordered to leave their homes and
motels, and businesses were closed for a short period of time. On July 16, 2002,
the State of South Dakota announced the results of its investigation of the
cause and origin of the fire. The State concluded that the fire was caused by
tree encroachment into and contact with a transmission line owned and maintained
by Black Hills Power, Inc.

         Black Hills Power is in the process of completing its own investigation
of the fire, and will request access to the materials that form the basis for
the State's conclusions. This investigation is not complete. Depending on the
outcome of this process, it is possible that claims will be made against Black
Hills Power for damages allegedly caused by the fire, for fire suppression costs
and costs of remediation of burned areas, for individual and business losses
relating to injury to personal and real property, and lost income. A civil
action has been commenced by the State against Black Hills Power, Inc., and we
anticipate others will intervene in this suit or will file separately.
