                                       14

 
          (iv)  whether the Money Market Quotes requested are to set forth a
     Money Market Margin or a Money Market Absolute Rate.

The Borrower may request offers to make Money Market Loans for more than one
Interest Period in a single Money Market Quote Request. No Money Market Quote
Request shall be given within five Euro-Dollar Business Days (or such other
number of days as the Borrower and the Administrative Agent may agree) of any
other Money Market Quote Request.

     (c)  Invitation for Money Market Quotes.  Promptly upon receipt of a Money
Market Quote Request, the Administrative Agent shall send to the Banks by telex
or facsimile transmission an Invitation for Money Market Quotes substantially in
the form of Exhibit C hereto, which shall constitute an invitation by the
Borrower to each Bank to submit Money Market Quotes offering to make the Money
Market Loans to which such Money Market Quote Request relates in accordance with
this Section.

     (d)  Submission and Contents of Money Market Quotes.  (i) Each Bank may
submit a Money Market Quote containing an offer or offers to make Money Market
Loans in response to any Invitation for Money Market Quotes. Each Money Market
Quote must comply with the requirements of this subsection (d) and must be
submitted to the Administrative Agent by telex or facsimile transmission at its
offices specified in or pursuant to Section 10.01 not later than (x) 2:00 P.M.
(New York City time) on the fourth Euro-Dollar Business Day prior to the
proposed date of Borrowing, in the case of a LIBOR Auction or (y) 9:30 A.M. (New
York City time) on the proposed date of Borrowing, in the case of an Absolute
Rate Auction (or, in either case, such other time or date as the Borrower and
the Administrative Agent shall have mutually agreed and shall have notified to
the Banks not later than the date of the Money Market Quote Request for the
first LIBOR Auction or Absolute Rate Auction for which such change is to be
effective); provided that Money Market Quotes submitted by the Administrative
Agent (or any affiliate of the Administrative Agent) in the capacity of a Bank
may be submitted, and may only be submitted, if the Administrative Agent or such
affiliate notifies the Borrower of the terms of the offer or offers contained
therein not later than (x) one hour prior to the deadline for the other Banks,
in the case of a LIBOR Auction or (y) 15 minutes prior to the deadline for the
other Banks, in the case of an Absolute Rate Auction. Subject to Articles 3 and
6, any Money Market Quote so made shall be irrevocable except with the written
consent of the Administrative Agent given on the instructions of the Borrower.

     (ii) Each Money  Market  Quote  shall be in  substantially  the form of
Exhibit D hereto and shall in any case specify:

                                       15

 
                    (A)  the proposed date of Borrowing,

                    (B)  the principal amount of the Money Market Loan for which
               each such offer is being made, which principal amount (w) may be
               greater than or less than the Commitment of the quoting Bank, (x)
               must be $5,000,000 or a larger multiple of $1,000,000, (y) may
               not exceed the principal amount of Money Market Loans for which
               offers were requested and (z) may be subject to an aggregate
               limitation as to the principal amount of Money Market Loans for
               which offers being made by such quoting Bank may be accepted,

                    (C)  in the case of a LIBOR Auction, the margin above or
               below the applicable London Interbank Offered Rate (the "Money
               Market Margin") offered for each such Money Market Loan,
               expressed as a percentage (specified to the nearest 1/10,000th of
               1%) to be added to or subtracted from such base rate,

                    (D)  in the case of an Absolute Rate Auction, the rate of
               interest per annum (specified to the nearest 1/10,000th of 1%)
               (the "Money Market Absolute Rate") offered for each such Money
               Market Loan, and

                    (E)  the identity of the quoting Bank.

A Money Market Quote may set forth up to five separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Money Market Quotes.

     (iii) Any Money Market Quote shall be disregarded if it:

                    (A)  is not substantially in conformity with Exhibit D
               hereto or does not specify all of the information required by
               subsection (d)(ii);

                    (B)  contains qualifying, conditional or similar language;

                    (C)  proposes terms other than or in addition to those set
               forth in the applicable Invitation for Money Market Quotes; or

                    (D)  arrives after the time set forth in subsection (d)(i).
                      

                                       16

 
     (e)  Notice to Borrower. The Administrative Agent shall promptly notify the
Borrower of the terms (x) of any Money Market Quote submitted by a Bank that is
in accordance with subsection (d) and (y) of any Money Market Quote that amends,
modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market Quote Request. Any
such subsequent Money Market Quote shall be disregarded by the Administrative
Agent unless such subsequent Money Market Quote is submitted solely to correct a
manifest error in such former Money Market Quote. The Administrative Agent's
notice to the Borrower shall specify (A) the aggregate principal amount of Money
Market Loans for which offers have been received for each Interest Period
specified in the related Money Market Quote Request, (B) the respective
principal amounts and Money Market Margins or Money Market Absolute Rates, as
the case may be, so offered and (C) if applicable, limitations on the aggregate
principal amount of Money Market Loans for which offers in any single Money
Market Quote may be accepted.

     (f)  Acceptance and Notice by Borrower.  Not later than 10:30 A.M. (New
York City time) on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Administrative Agent shall have
mutually agreed and shall have notified to the Banks not later than the date of
the Money Market Quote Request for the first LIBOR Auction or Absolute Rate
Auction for which such change is to be effective), the Borrower shall notify the
Administrative Agent of its acceptance or non-acceptance of the offers so
notified to it pursuant to subsection (e). In the case of acceptance, such
notice (such notice to be signed by any two of the Authorized Officers and
hereinafter referred to as a "Notice of Money Market Borrowing") shall specify
the aggregate principal amount of offers for each Interest Period that are
accepted. The Borrower may accept any Money Market Quote in whole or in part;
provided that:

          (i)   the aggregate principal amount of each Money Market Borrowing
     may not exceed the applicable amount set forth in the related Money Market
     Quote Request,

          (ii)  the principal amount of each Money Market Borrowing must be
     $10,000,000 or a larger multiple of $1,000,000,

          (iii) acceptance of offers may only be made on the basis of ascending
     Money Market Margins or Money Market Absolute Rates, as the
     case may be, and

                                       17

 
          (iv)  the Borrower may not accept any offer that is described in
     subsection (d)(iii) or that otherwise fails to comply with the requirements
     of this Agreement.

     (g)  Allocation by Administrative Agent. If offers are made by two or more
Banks with the same Money Market Margins or Money Market Absolute Rates, as the
case may be, for a greater aggregate principal amount than the amount in respect
of which such offers are accepted for the related Interest Period, the principal
amount of Money Market Loans in respect of which such offers are accepted shall
be allocated by the Administrative Agent among such Banks as nearly as possible
(in multiples of $1,000,000, as the Administrative Agent may deem appropriate)
in proportion to the aggregate principal amounts of such offers. Determinations
by the Administrative Agent of the amounts of Money Market Loans shall be
conclusive in the absence of manifest error.

     SECTION 2.04. Notice of Banks; Funding of Loans. (a) Upon receipt of a
Notice of Borrowing, the Administrative Agent shall promptly notify each Bank of
the contents thereof and of such Bank's share (if any) of such Borrowing and
such Notice of Borrowing shall not thereafter be revocable by the Borrower.

     (b)  Not later than 12:00 Noon (New York City time) on the date of each
Borrowing, each Bank participating therein shall make available its share of
such Borrowing, in Federal or other funds immediately available in New York
City, to the Administrative Agent at its address referred to in Section 10.01.
Unless the Administrative Agent determines that any applicable condition
specified in Article 3 has not been satisfied, the Administrative Agent will
make the funds so received from the Banks available to the Borrower at the
Administrative Agent's aforesaid address.

     (c)  Unless the Administrative Agent shall have received notice from a Bank
prior to the date of any Borrowing that such Bank will not make available to the
Administrative Agent such Bank's share of such Borrowing, the Administrative
Agent may assume that such Bank has made such share available to the
Administrative Agent on the date of such Borrowing in accordance with subsection
(b) of this Section 2.04 and the Administrative Agent may, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount.
If and to the extent that such Bank shall not have so made such share available
to the Administrative Agent, such Bank and the Borrower severally agree to repay
to the Administrative Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent, at (i) in the case of the Borrower, a rate per annum equal
to the interest rate applicable thereto pursuant to Section 2.07 and

                                       18

 
(ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay
to the Administrative Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Loan included in such Borrowing for purposes of
this Agreement.

     SECTION 2.05. Notes. (a) The Loans of each Bank shall be evidenced by a
single Note payable to the order of such Bank for the account of its Applicable
Lending Office in an amount equal to the aggregate unpaid principal amount of
such Bank's Loans.

     (b)  Each Bank may, by notice to the Borrower and the Administrative Agent,
request that its Loans of a particular type be evidenced by a separate Note in
an amount equal to the aggregate unpaid principal amount of such Loans. Each
such Note shall be in substantially the form of Exhibit A hereto with
appropriate modifications to reflect the fact that it evidences solely Loans of
the relevant type. Each reference in this Agreement to the "Note" of such Bank
shall be deemed to refer to and include any or all of such Notes, as the context
may require.

     (c)  Upon receipt of each Bank's Note pursuant to Section 3.01(a), the
Administrative Agent shall forward such Note to such Bank. Each Bank shall
record the date, amount, type and maturity of each Loan made by it and the date
and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Bank so elects in connection with any transfer or
enforcement of its Note, endorse on the schedule forming a part thereof
appropriate notations to evidence the foregoing information with respect to each
such Loan then outstanding; provided that the failure of any Bank to make any
such recordation or endorsement shall not affect the obligations of any Obligor
hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the
Borrower so to endorse its Note and to attach to and make a part of its Note a
continuation of any such schedule as and when required.

     SECTION 2.06.  Maturity of Loans.  (a) The Committed Loans shall mature,
and the principal amount thereof shall be due and payable, together with accrued
interest thereon, on the Termination Date.

     (b)  Each Money Market Loan included in any Money Market Borrowing shall
mature, and the principal amount thereof shall be due and payable, together with
accrued interest thereon, on the last day of the Interest Period applicable to
such Money Market Borrowing.

     SECTION 2.07.  Interest Rates.  (a) Each Base Rate Loan shall bear interest
on the outstanding principal amount thereof, for each day from the date such
Loan is made until it becomes due, at a rate per annum equal to the Base Rate
for such

                                       19

 
day. Such interest shall be payable at maturity, quarterly in arrears on the
last day of each March, June, September and December prior to maturity, and with
respect to the principal amount of any Base Rate Loan converted to a Euro-Dollar
Loan, on the date such amount is so converted. Any overdue principal of or
interest on any Base Rate Loan shall bear interest, payable on demand, for each
day until paid at a rate per annum equal to the sum of 2% plus the rate
otherwise applicable to Base Rate Loans for such day.

     (b)  Each Euro-Dollar Loan shall bear interest on the outstanding principal
amount thereof, for each day during each Interest Period applicable thereto, at
a rate per annum equal to the sum of the Euro-Dollar Margin for such day plus
the London Interbank Offered Rate applicable to such Interest Period. Such
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

     The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period means
the average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the
respective rates per annum at which deposits in dollars are offered to each of
the Reference Banks in the London interbank market at approximately 11:00 A.M.
(London time) two Euro-Dollar Business Days before the first day of such
Interest Period in an amount approximately equal to the principal amount of the
Euro-Dollar Loan of such Reference Bank to which such Interest Period is to
apply and for a period of time comparable to such Interest Period.

     (c)  Any overdue principal of or interest on any Euro-Dollar Loan shall
bear interest, payable on demand, for each day until paid at a rate per annum
equal to the higher of (i) the sum of 2% plus the Euro-Dollar Margin plus the
London Interbank Offered Rate applicable to such Loan at the date of such
payment was due and (ii) the sum of 2% plus the Euro-Dollar Margin plus the
quotient obtained (rounded upward, if necessary, to the next higher 1/100 of 1%)
by dividing (x) the average (rounded upward, if necessary, to the next higher
1/16 of 1%) of the respective rates per annum at which one day (or, if such
amount due remains unpaid more than three Euro-Dollar Business Days, then for
such other period of time not longer than six months as the Administrative Agent
may select) deposits in dollars in an amount approximately equal to such overdue
payment due to each of the Reference Banks are offered to such Reference Bank in
the London interbank market for the applicable period determined as provided
above by (y) 1.00 minus the Euro-Dollar Reserve Percentage (or, if the
circumstances described in clause (a) or (b) of Section 8.01 shall exist, at a
rate per annum equal to the sum of 2% plus the rate applicable to Base Rate
Loans for such day).

                                       20

 
          (d)  Subject to Section 8.01(a), each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the sum of the London
Interbank Offered Rate for such Interest Period (determined in accordance with
Section 2.07(b) as if the related Money Market LIBOR Borrowing were a Euro-
Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the Bank
making such Loan in accordance with Section 2.03. Each Money Market Absolute
Rate Loan shall bear interest on the outstanding principal amount thereof, for
the Interest Period applicable thereto, at a rate per annum equal to the Money
Market Absolute Rate quoted by the Bank making such Loan in accordance with
Section 2.03. Such interest shall be payable for each Interest Period on the
last day thereof and, if such Interest Period is longer than three months, at
intervals of three months after the first day thereof. Any overdue principal of
or interest on any Money Market Loan shall bear interest, payable on demand, for
each day until paid at a rate per annum equal to the sum of 2% plus the Base
Rate for such day.

          (e)  The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder. The Administrative Agent shall give prompt
notice to the Borrower and the participating Banks of each rate of interest so
determined, and its determination thereof shall be conclusive in the absence of
manifest error.

          (f)  Each Reference Bank agrees to use its best efforts to furnish
quotations to the Administrative Agent as contemplated by this Section. If any
Reference Bank does not furnish a timely quotation, the Administrative Agent
shall determine the relevant interest rate on the basis of the quotation or
quotations furnished by the remaining Reference Bank or Banks or, if none of
such quotations is available on a timely basis, the provisions of Section 8.01
shall apply.

          SECTION 2.08. Fees. (a) The Borrower shall pay to the Administrative
Agent for the account of the Banks ratably a facility fee at the Facility Fee
Rate. Such facility fee shall accrue (i) from and including the Closing Date to
but excluding the Termination Date (or earlier date of termination of the
Commitments in their entirety), on the daily aggregate amount of the Commitments
(whether used or unused) and (ii) from and including the Termination Date or
such earlier date of termination to but excluding the date the Loans and the
Letter of Credit Liabilities shall be repaid in their entirety, on the sum of
the daily aggregate outstanding principal amount of the Loans and the daily
aggregate Letter of Credit Liabilities.

                                      21

 
     (b)  The Borrower shall pay to the Agent (i) for the account of the Banks
ratably a Letter of Credit fee accruing daily on the aggregate amount then
available for drawing under all Letters of Credit at the LC Fee Rate and (ii)
for the account of each Issuing Bank a Letter of Credit fronting fee accruing
daily on the aggregate amount then available for drawing under all Letters of
Credit issued by such Issuing Bank at a rate per annum as determined from time
to time by the Borrower and such Issuing Bank.

     (c)  Accrued fees under this Section shall be payable quarterly in arrears
on each March 31, June 30, September 30 and December 31 and upon the date of
termination of the Commitments in their entirety (and, if later, the date the
Loans and Letter of Credit Liabilities shall be repaid in their entirety).

     SECTION 2.09.  Optional Termination or Reduction of Commitments. The
Borrower may, upon at least three Domestic Business Days' notice to the
Administrative Agent, (i) terminate the Commitments at any time, if no Loans or
Letter of Credit Liabilities are outstanding at such time or (ii) ratably reduce
from time to time by an aggregate amount of $25,000,000 or any larger multiple
of $5,000,000, the aggregate amount of the Commitments in excess of the sum of
the aggregate outstanding principal amount of the Loans and the aggregate Letter
of Credit Liabilities. Upon receipt of any notice pursuant to this Section 2.09,
the Administrative Agent shall promptly notify the Banks of the contents of such
notice.

     SECTION 2.10.  Scheduled Termination of Commitments. The Commitments shall
terminate on the Termination Date, and any Loans then outstanding (together with
accrued interest thereon) shall be due and payable on such date.

     SECTION 2.11.  Method of Electing Interest Rates. (a) The Loans included in
each Committed Borrowing shall bear interest initially at the type of rate
specified by the Borrower in the applicable Notice of Committed Borrowing.
Thereafter, the Borrower may from time to time elect to change or continue the
type of interest rate borne by each Group of Loans (subject to subsection (d) of
this Section and the provisions of Article 8), as follows:

          (i)  if such Loans are Base Rate Loans, the Borrower may elect to
     convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day;
     and

          (ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to
     convert such Loans to Base Rate Loans or elect to continue such Loans as
     Euro-Dollar Loans for an additional Interest Period, subject to Section

                                      22

 
          2.14 if any such conversion or continuation is effective on
          any day other than the last day of an Interest Period applicable to
          such Loans.
         
Each such  election  shall be made by delivering a notice (a "NOTICE OF INTEREST
RATE ELECTION") to the Administrative  Agent not later than 10:30 A.M. (New York
City  time) on the third  Euro-Dollar  Business  Day before  the  conversion  or
continuation  selected in such notice is to be  effective.  A Notice of Interest
Rate Election may, if it so specifies,  apply to only a portion of the aggregate
principal amount of the relevant Group of Loans;  provided that (i) such portion
is allocated  ratably among the Loans comprising such Group and (ii) the portion
to which such notice  applies,  and the  remaining  portion to which it does not
apply,  are each at least  $10,000,000  or any  larger  amount in  multiples  of
$1,000,000  (unless such  portion is  comprised of Base Rate Loans).  If no such
notice is timely  received before the end of an Interest Period for any Group of
Euro-Dollar  Loans, the Borrower shall be deemed to have elected that such Group
of Loans be converted to Base Rate Loans at the end of such Interest Period.

          (b)  Each Notice of Interest Rate Election shall specify:

               (i)   the Group of Loans (or portion thereof) to which such
          notice applies;

               (ii)  the date on which the conversion or continuation selected
          in such notice is to be effective, which shall comply with the
          applicable clause of subsection (a) above;

               (iii) if the Loans comprising such Group are to be converted, the
          new type of Loans and, if the Loans resulting from such conversion are
          to be Euro-Dollar Loans, the duration of the initial Interest Period
          applicable thereto; and

               (iv) if such Loans are to be continued as Euro-Dollar Loans for
          an additional Interest Period, the duration of such additional
          Interest Period.

Each  Interest  Period  specified in a Notice of Interest  Rate  Election  shall
comply with the provisions of the definition of Interest Period.

          (c)  Promptly after receiving a Notice of Interest Rate Election from
the Borrower pursuant to subsection (a) above, the Administrative Agent shall
notify each Bank of the contents thereof and such notice shall not thereafter be
revocable by the Borrower.

                                      23

 
          (d)  The Borrower shall not be entitled to elect to convert any
Committed Loans to, or continue any Committed Loans for an additional Interest
Period as, Euro-Dollar Loans if (i) the aggregate principal amounts of any Group
of Euro- Dollar Loans created or continued as a result of such election would be
less than $10,000,000 or (ii) a Default shall have occurred and be continuing
when the Borrower delivers notice of such election to the Administrative Agent.

          SECTION 2.12. Optional  Prepayments.  (a)  Subject in the case of any
Euro-Dollar  Loan to Section 2.14, the Borrower may, in the case of the Group of
Base Rate Loans (or any Money Market Borrowing bearing interest at the Base Rate
pursuant to Section  8.01(a)),  upon at least one Domestic Business Day's notice
to the Administrative  Agent, prepay such Group or Borrowing,  or in the case of
any Group of Euro-Dollar  Loans, upon at least three Euro-Dollar  Business Days'
notice to the Administrative  Agent, prepay such Group, in each case in whole at
any time, or from time to time in part in amounts aggregating $10,000,000 or any
larger  multiple of  $1,000,000,  by paying the  principal  amount to be prepaid
together  with accrued  interest  thereon to the date of  prepayment.  Each such
optional  prepayment shall be applied to prepay ratably the Loans of the several
Banks included in such Group or Borrowing.

          (b)  Except as provided in Section 2.12(a), the Borrower may not
prepay all or any portion of the principal amount of any Money Market Loan prior
to the maturity thereof.

          (c)  Upon receipt of a notice of prepayment pursuant to this Section,
the Administrative Agent shall promptly notify each Bank of the contents thereof
and of such Bank's ratable share (if any) of such prepayment and such notice
shall not thereafter be revocable by the Borrower.

          SECTION 2.13. General Provisions as to Payments. (a) The Borrower
shall make each payment of principal of, and interest on, the Loans, of Letter
of Credit Liabilities and of fees hereunder, not later than 2:00 P.M. (New York
City time) on the date when due, in Federal or other funds immediately available
in New York City and in the lawful currency of the United States, to the
Administrative Agent at its address referred to in Section 10.01. The
Administrative Agent will promptly distribute to each Bank its ratable share of
each such payment received by the Administrative Agent for the account of the
Banks. Whenever any payment of principal of, or interest on, the Base Rate
Loans, of Letter of Credit Liabilities or of fees shall be due on a day which is
not a Domestic Business Day, the date for payment thereof shall be extended to
the next succeeding Domestic Business Day. Whenever any payment of principal of,
or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-
Dollar Business Day, the date for payment thereof shall be extended to the 

                                      24

 
next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day
falls in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Dollar Business Day. Whenever any payment of
principal of, or interest on, the Money Market Loans shall be due on a day which
is not a Euro-Dollar Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Dollar Business Day. If the date for any
payment of principal is extended by operation of law or otherwise, interest
thereon shall be payable for such extended time.

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

          SECTION 2.14. Funding  Losses.  If the Borrower  makes any payment of
principal  with  respect  to any  Fixed  Rate  Loan or any  Fixed  Rate  Loan is
converted  to a  different  type  of  Loan  (pursuant  to  Article  2, 6 or 8 or
otherwise) on any day other than the last day of an Interest  Period  applicable
thereto,  or the last day of an  applicable  period  fixed  pursuant  to Section
2.07(c),  or if the Borrower  fails to borrow,  prepay,  convert or continue any
Fixed Rate Loans  after  notice  has been given to any Bank in  accordance  with
Section  2.04(a),  2.11(c) or 2.12(c),  the Borrower  shall  reimburse each Bank
within 15 days after demand for any resulting loss or expense incurred by it (or
by an  existing  or, in the case of the  failure of the  Borrower  to borrow any
Fixed Rate  Loans,  prospective  Participant  in the  related  Loan),  including
(without  limitation)  any loss incurred in obtaining,  liquidating or employing
deposits from third  parties,  but excluding loss of margin for the period after
any such  payment,  conversion  or  continuation  or failure to borrow,  prepay,
convert  or  continue,  provided  that such Bank  shall  have  delivered  to the
Borrower a  certificate  as to the amount of such loss or  expense  and  setting
forth the  calculation  thereof,  which  certificate  shall be conclusive in the
absence of manifest error.

          SECTION 2.15. Computation of Interest and Fees.  Interest based on the
Prime Rate  hereunder  shall be  computed on the basis of a year of 365 days (or
366  days in a leap  year)  and  paid  for the  actual  number  of days  elapsed
(including the 

                                      25

 
first day but excluding the last day). All other interest and all facility and
Letter of Credit fees shall be computed on the basis of a year of 360 days and
paid for the actual number of days elapsed (including the first day but
excluding the last day).

          SECTION 2.16. Regulation  D  Compensation.  For so long  as any  Bank
maintains reserves against "Eurocurrency  liabilities" (or any other category of
liabilities  which includes  deposits by reference to which the interest rate on
Euro- Dollar Loans is  determined  or any  category of  extensions  of credit or
other assets which includes loans by a non-United  States office of such Bank to
United  States  residents),  and as a  result  the  cost  to such  Bank  (or its
Euro-Dollar  Lending Office) of making or maintaining  its Euro-Dollar  Loans is
increased,  then such Bank may  require the  Borrower to pay,  contemporaneously
with each payment of interest on the Euro-Dollar Loans,  additional  interest on
the  related  Euro-Dollar  Loan of such  Bank at a rate per  annum up to but not
exceeding the excess of (i) (A) the  applicable  London  Interbank  Offered Rate
divided  by (B) one  minus  the  Euro-Dollar  Reserve  Percentage  over (ii) the
applicable London Interbank Offered Rate. Any Bank wishing to require payment of
such additional interest (x) shall so notify the Borrower and the Administrative
Agent, in which case such additional  interest on the Euro-Dollar  Loans of such
Bank shall be payable to such Bank at the place  indicated  in such  notice with
respect to each Interest Period commencing at least three  Euro-Dollar  Business
Days after the giving of such  notice and (y) shall  furnish to the  Borrower at
least five  Euro-Dollar  Business  Days prior to each date on which  interest is
payable on the  Euro-Dollar  Loans an officer's  certificate  setting  forth the
amount to which such Bank is then  entitled  under this Section  (which shall be
consistent  with  such  Bank's  good  faith  estimate  of the level at which the
related  reserves  are  maintained  by  it).  Each  such  certificate  shall  be
accompanied by such information as the Borrower may reasonably request as to the
computation set forth therein.

          SECTION 2.17. Letters  of  Credit.  (a)  Subject  to  the  terms  and
conditions hereof, each Issuing Bank agrees to issue Letters of Credit hereunder
from time to time  before  the tenth day before  the  Termination  Date upon the
request of the Borrower;  provided that, immediately after each Letter of Credit
is issued,  (i) the aggregate amount of the Letter of Credit  Liabilities  shall
not exceed the Letter of Credit  Commitment and (ii) the aggregate amount of the
Letter of Credit Liabilities plus the aggregate  outstanding amount of all Loans
shall not  exceed  the  aggregate  amount of the  Commitments.  Upon the date of
issuance by an Issuing  Bank of a Letter of Credit,  the  Issuing  Bank shall be
deemed, without further action by any party hereto, to have sold to each Bank,
and each Bank shall be deemed, without further action by any party hereto, to
have purchased from the Issuing Bank, a participation in such Letter of Credit
and the related Letter of Credit Liabilities in the proportion their respective
Commitments bear to the aggregate Commitments.

                                      26

 
     (b)  The Borrower shall give the Issuing Bank notice at least five Domestic
Business Days prior to the requested issuance of a Letter of Credit specifying
the date such Letter of Credit is to be issued, and describing the terms of such
Letter of Credit and the nature of the transactions to be supported thereby
(such notice, including any such notice given in connection with the extension
of a Letter of Credit, a "Notice of Issuance"). Upon receipt of a Notice of
Issuance, the Issuing Bank shall promptly notify the Agent, and the Agent shall
promptly notify each Bank of the contents thereof and of the amount of such
Bank's participation in such Letter of Credit. The issuance by the Issuing Bank
of each Letter of Credit shall, in addition to the conditions precedent set
forth in Article 3, be subject to the conditions precedent that such Letter of
Credit shall be in such form and contain such terms as shall be reasonably
satisfactory to the Issuing Bank and that the Borrower shall have executed and
delivered such other instruments and agreements relating to such Letter of
Credit as the Issuing Bank shall have reasonably requested. The Borrower shall
also pay to the Issuing Bank for its own account issuance, drawing, amendment
and extension charges in the amounts and at the times agreed between the
Borrower and the Issuing Bank. The extension or renewal of any Letter of Credit
shall be deemed to be an issuance of such Letter of Credit, and if any Letter of
Credit contains a provision pursuant to which it is deemed to be extended unless
notice of termination is given by the Issuing Bank, the Issuing Bank shall
timely give such notice of termination unless it has theretofore timely received
a Notice of Issuance and the other conditions to issuance of a Letter of Credit
have also theretofore been met with respect to such extension. No Letter of
Credit shall have a term extending or be so extendible beyond the fifth Domestic
Business Day preceding the Termination Date.

     (c)  Upon receipt from the beneficiary of any Letter of Credit of any
notice of a drawing under such Letter of Credit, the Issuing Bank shall notify
the Agent and the Agent shall promptly notify the Borrower and each other Bank
as to the amount to be paid as a result of such demand or drawing and the
payment date. The Borrower shall be irrevocably and unconditionally obligated
forthwith to reimburse the Issuing Bank for any amounts paid by the Issuing Bank
upon any drawing under any Letter of Credit, without presentment, demand,
protest or other formalities of any kind. All such amounts paid by the Issuing
Bank and remaining unpaid by the Borrower shall bear interest, payable on
demand, for each day until paid at a rate per annum equal to the sum of 2% plus
the rate applicable to Base Rate Loans for such day. In addition, each Bank will
pay to the Agent, for the account of the Issuing Bank, immediately upon the
Issuing Bank's demand at any time during the period commencing after such
drawing until reimbursement therefor in full by the Borrower, an amount equal to
such Bank's ratable share of such drawing (in proportion to its participation
therein), together with interest on such amount for each day from the date of
the Issuing Bank's demand for such payment (or, if such demand is made after
12:00 Noon (New York City time) on

                                      27

 
such date, from the next succeeding Domestic Business Day) to the date of
payment by such Bank of such amount at a rate of interest per annum equal to the
Federal Funds Rate. The Issuing Bank will pay to each Bank ratably all amounts
received from the Borrower for application in payment of its reimbursement
obligations in respect of any Letter of Credit, but only to the extent such Bank
has made payment to the Issuing Bank in respect of such Letter of Credit
pursuant hereto.

     (d)  The obligations of the Borrower and each Bank under subsection (c)
above shall be absolute, unconditional and irrevocable, and shall be performed
strictly in accordance with the terms of this Agreement, under all circumstances
whatsoever, including without limitation the following circumstances:

          (i)   any lack of validity or enforceability of this Agreement or any
     Letter of Credit or any document related hereto or thereto;

          (ii)  any amendment, waiver of or any consent to departure from all or
     any of the provisions of this Agreement, any Letter of Credit or any
     document related hereto or thereto;

          (iii) the use which may be made of the Letter of Credit by, or any act
     or omission of, a beneficiary of a Letter of Credit (or any Person for whom
     the beneficiary may be acting);

          (iv)  the existence of any claim, set-off, defense or other rights
     that the Borrower may have at any time against a beneficiary of a Letter of
     Credit (or any Person for whom the beneficiary may be acting), the Banks
     (including the Issuing Bank) or any other Person, whether in connection
     with this Agreement or the Letter of Credit or any document related hereto
     or thereto or any unrelated transaction;

          (v)   any statement or any other document presented under a Letter of
     Credit proving to be forged, fraudulent or invalid in any respect or any
     statement therein being untrue or inaccurate in any respect whatsoever;

          (vi)  payment under a Letter of Credit to the beneficiary of such
     Letter of Credit against presentation to the Issuing Bank of a draft or
     certificate that does not comply with the terms of the Letter of Credit; or

          (vii) any other act or omission to act or delay of any kind by any
     Bank (including the Issuing Bank), the Agent or any other Person or any
     other event or circumstance whatsoever that might, but for the provisions

                                      28

 
          of this subsection (vii), constitute a legal or equitable discharge of
          the Borrower's or the Bank's obligations hereunder.

          (e)  The Borrower hereby indemnifies and holds harmless each Bank
(including each Issuing Bank) and the Agent from and against any and all claims,
damages, losses, liabilities, costs or expenses which such Bank or the Agent may
incur (including, without limitation, any claims, damages, losses, liabilities,
costs or expenses which the Issuing Bank may incur by reason of or in connection
with the failure of any other Bank to fulfill or comply with its obligations to
such Issuing Bank hereunder (but nothing herein contained shall affect any
rights the Borrower may have against such defaulting Bank)), and none of the
Banks (including an Issuing Bank) nor the Agent nor any of their officers or
directors or employees or agents shall be liable or responsible, by reason of or
in connection with the execution and delivery or transfer of or payment or
failure to pay under any Letter of Credit, including without limitation any of
the circumstances enumerated in subsection (d) above, as well as (i) any error,
omission, interruption or delay in transmission or delivery of any messages, by
mail, cable, telegraph, telex or otherwise, (ii) any error in interpretation of
technical terms, (iii) any loss or delay in the transmission of any document
required in order to make a drawing under a Letter of Credit, (iv) any
consequences arising from causes beyond the control of an Issuing Bank,
including without limitation any government acts, or any other circumstances
whatsoever in making or failing to make payment under such Letter of Credit;
provided that the Borrower shall not be required to indemnify any Issuing Bank
for any claims, damages, losses, liabilities, costs or expenses, and the
Borrower shall have a claim for direct (but not consequential) damage suffered
by it, to the extent found by a court of competent jurisdiction to have been
caused by (x) the failure of such Issuing Bank to meet the standards prescribed
by the UCP in determining whether a request presented under any Letter of Credit
complied with the terms of such Letter of Credit or (y) such Issuing Bank's
failure to pay under any Letter of Credit after the presentation to it of a
request strictly complying with the terms and conditions of such Letter of
Credit. Nothing in this subsection (e) is intended to limit the obligations of
the Borrower under Section 2.17(c) of this Agreement. To the extent the Borrower
is obligated to but does not indemnify an Issuing Bank as required by this
subsection, the Banks agree to do so ratably in accordance with their
Commitments.

The Administrative Agent shall promptly notify the Borrower and the Banks of the
Closing  Date,  and such notice shall be  conclusive  and binding on all parties

Section.

                                       34

 
respects on the date as of which such information is stated or certified. The

are in compliance, in all material respects, with all applicable laws,
ordinances, rules, regulations, guidelines and other requirements of
governmental authorities except where the necessity of compliance therewith is

of resignation, then the retiring Administrative Agent may, on behalf of the
Banks, appoint a successor Administrative Agent, which shall be a commercial
bank organized or licensed under the laws of the United States of America or of

London Interbank Offered Rate as determined by the Administrative Agent will not
adequately and fairly reflect the cost to such Banks of funding their Euro-
Dollar Loans for such Interest Period, the Administrative Agent shall forthwith
give notice thereof to the Borrower and the Banks, whereupon until the
Administrative Agent notifies the Borrower that the circumstances giving rise to
such suspension no longer exist (i) the obligations of the Banks to make Euro-

borrow on such date, (i) if such Fixed Rate Borrowing is a Euro-Dollar
Borrowing, such Borrowing shall instead be made as a Base Rate

(whether or not having the force of law) of any such authority, central bank or
comparable agency shall make it unlawful or impossible for any Bank (or its 
Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and
such Bank shall so notify the Administrative Agent, the Administrative Agent
shall forthwith give notice thereof to the other Banks and the Borrower,
whereupon until such Bank notifies the Borrower and the Administrative Agent
that the circumstances giving rise to such suspension no longer exist, the
obligation of such Bank to make Euro-Dollar Loans, or to continue or convert
outstanding Loans as or into Euro-Dollar Loans, shall be suspended. Before
giving any notice to the Administrative Agent pursuant to this Section, such
Bank shall designate a different Euro-Dollar Lending Office if such designation
will avoid the need for giving such notice and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. If such notice is given, each
Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base Rate
Loan either (a) on the last day of the then current Interest Period applicable
to such Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund
such Loan as a Euro-Dollar Loan to such day or (b) immediately if such Bank
shall determine that it may not lawfully continue to maintain and fund such Loan
as a Euro-Dollar Loan to such day.

     Section 8.03.  Increased Cost and Reduced Return.  (a) If on or after (x)
the date hereof, in the case of any Committed Loan or Letter of Credit or any
obligation to make Committed Loans or issue or participate in any Letter of
Credit or (y) the date of the related Money Market Quote, in the case of any
Money Market Loan, the adoption of any applicable law, rule or regulation, or
any change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of

                                       48

 
Governors of the Federal Reserve System, but excluding with respect to any Euro-
Dollar Loan any such requirement with respect to which such Bank is entitled to
compensation during the relevant Interest Period under Section 2.16), special
deposit, insurance assessment or similar requirement against assets of, deposits
with or for the account of, or credit extended by, any Bank (or its Applicable
Lending Office) or shall impose on any Bank (or its Applicable Lending Office)
or on the London interbank market any other condition affecting its Fixed Rate
Loans, its Note or its obligation to make Fixed Rate Loans or its obligations
hereunder in respect of Letters of Credit and the result of any of the foregoing
is to increase the cost to such Bank (or its Applicable Lending Office) of
making or maintaining any Fixed Rate Loan or of issuing or participating in any
Letter of Credit, or to reduce the amount of any sum received or receivable by
such Bank (or its Applicable Lending Office) under this Agreement or under its
Note with respect thereto, by an amount deemed by such Bank to be material,
then, within 15 days after demand by such Bank (with a copy to the
Administrative Agent), the Borrower shall pay to such Bank such additional
amount or amounts as will compensate such Bank for such increased cost or
reduction.

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

     (c)  Each Bank will promptly notify the Borrower and the Administrative
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Bank to compensation pursuant to this Section and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank.  A certificate
of any Bank claiming compensation under this Section and setting forth the

                                       49

 
additional amount or amounts to be paid to it hereunder shall be conclusive in
the absence of manifest error.  In determining such amount, such Bank may use
any reasonable averaging and attribution methods.  Notwithstanding the foregoing
subsections 8.03(a) and 8.03(b) of this Section 8.03, the Borrower shall only be
obligated to compensate any Bank for any amount arising or accruing during (i)
any time or period commencing not more than 180 days prior to the date on which
such Bank notifies the Administrative Agent and the Borrower that it proposes to
demand such compensation and identifies to the Administrative Agent and the
Borrower the statute, regulation or other basis upon which the claimed
compensation is or will be based and (ii) any time or period during which
because of the retroactive application of such statute, regulation or other such
basis, such Bank did not know in good faith that such amount would arise or
accrue.

     Section 8.04.  Taxes.  (a) Any and all payments by any Obligor hereunder
shall be made free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
penalties, interest, expenses and similar liabilities with respect thereto,
excluding (i) in the case of each Bank and the Administrative Agent, taxes
imposed on its income, and franchise and similar taxes imposed on it, by the
jurisdiction under the laws of which such Bank or the Administrative Agent, as
the case may be, shall be organized or any political subdivision thereof, (ii)
in the case of each Bank, taxes imposed on its income, and franchise and similar
taxes imposed on it, by the jurisdiction of such Bank's Applicable Lending
Office or any political subdivision thereof or in which such Bank's principal
executive office is located or any political subdivision thereof and (iii) any
Taxes imposed as a result of a change of such Bank's Applicable Lending Office
to the extent such Taxes would not have been imposed absent such change;
provided however, that (x) a change in such Bank's Applicable Lending Office to
which the Obligor has consented and (y) a change in such Bank's Applicable
Lending Office as a result of legal or regulatory restrictions shall not
constitute a change for the purposes of this Section 8.04 (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes"). Each Obligor agrees that, if any Obligor
shall be required by law to deduct any Taxes from or in respect of any sum
payable hereunder to any Bank or the Administrative Agent, (A) the sum payable
to such Bank or the Administrative Agent shall be increased as may be necessary
so that after making all required deductions for Taxes (including deductions
applicable to additional sums payable under this Section 8.04), such Bank or the
Administrative Agent, as the case may be, shall receive an amount equal to the
sum it would have received had no such deductions been made, (B) such Obligor
shall make such deductions and (C) such Obligor shall pay the full amount
deducted to the relevant taxing authority or other authority in accordance with
applicable law.

                                       50

 
     (b)  In addition, each Obligor agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies which shall arise from any payment made under, or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or any
Note or Letter of Credit (all such taxes, charges or levies being hereinafter
referred to as "Other Taxes").

     (c)  Each Obligor agrees to indemnify each Bank and the Administrative
Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other
Taxes imposed on amounts payable under this Section 8.04) paid by such Bank or
the Administrative Agent or any penalties, interest, expenses and similar
liabilities arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted provided that such Bank has
acted in good faith with respect to such Taxes or Other Taxes and that such Bank
reasonably cooperates with the Obligors in challenging such Taxes or Other
Taxes.  Each indemnification under this paragraph (c) shall be made within 30
days from the date such Bank or the Administrative Agent makes demand therefor.

     (d)  Each Bank shall use reasonable efforts (consistent with legal and
regulatory restrictions) (x) to file any certificate or document or to furnish
any information as reasonably requested by any Obligor pursuant to any
applicable treaty, law, rule or regulation or (y) to designate a different
Lending Office if the making of such a filing, the furnishing of such
information or the designation of such other Lending Office would avoid the need
for or reduce the amount of any additional amounts payable by any Obligor
pursuant to this Section 8.04 and would not, in the reasonable judgment of such
Bank, be disadvantageous to such Bank.  Notwithstanding the foregoing, it is
understood and agreed that nothing in this Section 8.04 shall interfere with the
rights of any Bank to conduct its fiscal or tax affairs in such manner as it
deems fit.

     (e)  Within 90 days after the date of any payment of Taxes, the Obligors
will furnish to the Administrative Agent notarized copies for each Bank of the
original receipt evidencing payment thereof.  If no Taxes shall be payable in
respect of any payment under this Agreement, the Obligors will, upon the
reasonable request of the Administrative Agent, furnish to the Administrative
Agent a certificate in form reasonably acceptable to the Administrative Agent's
counsel confirming that such payment is exempt from or not subject to Taxes.

     (f)  For any period with respect to which a Bank has failed to provide
the Obligors with the appropriate form pursuant to Section 8.04(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which such form originally was required to be provided), such Bank
shall 

                                       51

 
not be entitled to indemnification under Section 8.04(a) or (b) with
respect to Taxes imposed by the United States; provided that if a Bank, which is
otherwise exempt from or subject to a reduced rate of withholding tax, becomes
subject to Taxes because of its failure to deliver a form required hereunder,
the Obligors shall take such steps as such Bank shall reasonably request to
assist such Bank to recover such Taxes.

     Section 8.05. Base Rate Loans Substituted for Affected Fixed Rate Loans. If
(i) the obligation of any Bank to make or to continue or convert outstanding
Loans as or to Euro-Dollar Loans has been suspended pursuant to Section 8.02 or
(ii) any Bank has demanded compensation under Section 8.03 or 8.04 with respect
to its Euro-Dollar Loans and the Borrower shall, by at least five Euro-Dollar
Business Days' prior notice to such Bank through the Administrative Agent, have
elected that the provisions of this Section shall apply to such Bank, then,
unless and until such Bank notifies the Borrower that the circumstances giving
rise to such suspension or demand for compensation no longer exist:

     (a)  all Loans which would otherwise be made by such Bank as (or continued
as or converted to) Euro-Dollar Loans shall instead be Base Rate Loans (on which
interest and principal shall be payable contemporaneously with the related Euro-
Dollar Loans of the other Banks), and

     (b)  after each of its Euro-Dollar Loans has been repaid (or converted),
all payments of principal which would otherwise be applied to repay such Euro-
Dollar Loans shall be applied to repay its Base Rate Loans instead.

If such Bank notifies the Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first
day of the next succeeding Interest Period applicable to the related Euro-Dollar
Loans of the other Banks.

     Section 8.06.  Substitution of Bank. If (i) the obligation of any Bank to
make or to convert or continue outstanding Loans as or into Euro-Dollar Loans
has been suspended pursuant to Section 8.02 or (ii) any Bank has demanded
compensation under Section 8.03 or 8.04, the Borrower shall have the right, with
the assistance of the Administrative Agent, to designate a substitute bank or
banks (which may be one or more of the Banks) mutually satisfactory to the
Borrower, the Administrative Agent (whose consent shall not be unreasonably
withheld) and the issuing banks under the Related Documents to purchase for
cash, pursuant to an Assignment and Assumption Agreement in substantially the
form of Exhibit I hereto, the outstanding loans of such Bank and assume the
commitment and letter of credit liabilities of such Bank (and its affiliates)
under each of the Related

                                      52

 
Documents, without recourse to or warranty by, or expense to, such Bank, for a
purchase price equal to the principal amount of all of such Bank's outstanding
loans and funded letter of credit liabilities plus any accrued but unpaid
interest thereon and the accrued but unpaid fees in respect of such Bank's
commitments and letter of credit liabilities plus such amount, if any, as would
be payable pursuant to the funding loss indemnities in the Related Documents if
the outstanding loans of such Bank were prepaid in their entirety on the date of
consummation of such assignment.
                     
                                   ARTICLE 9
                                      
                                    Guaranty

     Section 9.01. The Guaranty. Each Guarantor hereby unconditionally, jointly
and severally, absolutely and irrevocably guarantees the full and punctual
payment (whether at stated maturity, upon acceleration or otherwise) of all
amounts payable by the Borrower under the Financing Documents including, without
limitation, the principal of and interest on each Note issued by the Borrower
pursuant to this Agreement. Upon failure by the Borrower to pay punctually any
such amount, each Guarantor shall forthwith on demand pay the amount not so paid
at the place and in the manner specified in this Agreement.

     Section 9.02. Guaranty Unconditional. The obligations of each Guarantor
hereunder shall be unconditional, absolute and irrevocable and, without limiting
the generality of the foregoing, shall not be released, discharged or otherwise
affected by:

     (a)  any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of any other Obligor under any of the Financing
Documents, by operation of law or otherwise;

     (b)  any modification or amendment of or supplement to any of the Financing
Documents;

     (c)  any release, non-perfection or invalidity of any direct or indirect
security for any obligation of any other Obligor under any of the Financing
Documents;

     (d)  any change in the corporate existence, structure or ownership of any
Obligor, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting any other Obligor or its assets or any resulting release or

                                       53

 
discharge of any obligation of any other Obligor contained in any of the
Financing Documents;

     (e)  the existence of any claim, set-off or other rights which any
Obligor may have at any time against any other Obligor, the Administrative
Agent, any Bank or any other corporation or person, whether in connection with
any of the Financing Documents or any unrelated transactions, provided that
nothing herein shall prevent the assertion of any such claim by separate suit or
compulsory counterclaim;

     (f)  any invalidity or unenforceability relating to or against any other
Obligor for any reason of any of the Financing Documents, or any provision of
applicable law or regulation purporting to prohibit the payment by any other
Obligor of the principal of or interest on any Note or any other amount payable
under any of the Financing Documents; or

     (g)  any other act or omission to act or delay of any kind by any
Obligor, the Administrative Agent, any Bank or any other corporation or person
or any other circumstance whatsoever which might, but for the provisions of this
paragraph, constitute a legal or equitable discharge of or defense to any
Guarantor's obligations hereunder.

     Section 9.03. Discharge Only upon Payment in Full; Reinstatement in Certain
Circumstances. Each Guarantor's obligations hereunder shall remain in full
force and effect until the Commitments shall have terminated and the principal
of and interest on the Notes and all other amounts payable by the Borrower under
the Financing Documents shall have been paid in full. If at any time any payment
of the principal of or interest on any Note or any other amount payable by the
Borrower under the Financing Documents is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Borrower or otherwise, each Guarantor's obligations hereunder with respect to
such payment shall be reinstated as though such payment had been due but not
made at such time.

     Section 9.04. Waiver by Each of the Guarantors. Each Guarantor irrevocably
waives acceptance hereof, presentment, demand, protest and any notice not
provided for herein, as well as any requirement that at any time any action be
taken by any corporation or person against any other Obligor or any other
corporation or person.

     Section 9.05. Subrogation. Upon the making by any Guarantor of any payment
hereunder, such Guarantor shall be subrogated to the rights of the payee against
the Borrower with respect to such payment; provided that such Guarantor

                                       54

 
shall not enforce any right to receive any payment by way of subrogation until
all amounts of principal of and interest on the Loans, all Letter of Credit
Liabilities and all other amounts payable by the Borrower under this Agreement
shall have been paid in full and the Commitments shall have terminated.

     Section 9.06. Stay of Acceleration. If acceleration of the time for payment
of any amount payable by the Borrower under any of the Financing Documents is
stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all
such amounts otherwise subject to acceleration under the terms of this Agreement
shall nonetheless be payable by each Guarantor hereunder forthwith on demand by
the Administrative Agent made at the request of the requisite proportion of the
Banks specified in Article 6.

     Section 9.07. Limit of Liability. The obligations of each Guarantor
hereunder shall be limited to an aggregate amount equal to the largest amount
that would not render its obligations hereunder subject to avoidance under any
applicable bankruptcy, insolvency or similar law.

                                   ARTICLE 10

                                 Miscellaneous

     Section 10.01. Notices. All notices, requests and other communications to
any party hereunder shall be in writing (including bank wire, telex, facsimile
transmission or similar writing) and shall be given to such party: (x) in the
case of any Obligor or the Administrative Agent, at its address, facsimile
number or telex number set forth on the signature pages hereof, (y) in the case
of any Bank, at its address, facsimile number or telex number set forth in its
Administrative Questionnaire or (z) in the case of any party, such other
address, facsimile number or telex number as such party may hereafter specify
for the purpose by notice to the Administrative Agent and the Borrower. Each
such notice, request or other communication shall be effective (i) if given by
telex, when such telex is transmitted to the telex number specified in this
Section and the appropriate answerback is received, (ii) if given by facsimile
transmission, when transmitted to the facsimile number specified in this Section
and confirmation of receipt is received, (iii) if given by mail, 10 days after
such communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iv) if given by any other means, when delivered at
the address specified in this Section; provided that notices to the
Administrative Agent or the Issuing Bank under Article 2 or Article 8 shall not
be effective until received.

     Section 10.02. No Waivers. No failure or delay by the Administrative Agent
or any Bank in exercising any right, power or privilege under any

                                       55

 
Financing Document shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies
provided in the Financing Documents shall be cumulative and not exclusive of any
rights or remedies provided by law.

     Section 10.03. Expenses; Indemnification. (a) The Borrower shall pay (i)
all out-of-pocket expenses of the Administrative Agent, including fees and
disbursements of Davis Polk & Wardwell, special counsel for the Agents,
reasonably incurred in connection with the preparation of the Financing
Documents, any waiver or consent hereunder or thereunder or any amendment hereof
or thereof or any Default or alleged Default hereunder or thereunder and (ii) if
an Event of Default occurs, all out-of-pocket expenses incurred by the
Administrative Agent and each Bank, including (without duplication) the fees and
disbursements of outside counsel and the allocated cost of inside counsel, in
connection with such Event of Default and collection, bankruptcy, insolvency and
other enforcement proceedings resulting therefrom.

     (b)  The Borrower agrees to indemnify the Administrative Agent and each
Bank, their respective affiliates and the respective directors, officers, agents
and employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be reasonably incurred by such Indemnitee in
connection with any investigative, administrative or judicial proceeding
(whether or not such Indemnitee shall be designated a party thereto) brought or
threatened relating to or arising out of the Financing Documents or any actual
or proposed use of proceeds of Loans; provided that no Indemnitee shall have the
right to be indemnified hereunder for such Indemnitee's own gross negligence or
willful misconduct as determined by a court of competent jurisdiction.

     Section 10.04. Sharing; Set-Offs. (a) Each Bank agrees that if it shall, by
exercising any right of set-off or counterclaim or otherwise, receive payment of
a proportion of the aggregate amount of principal and interest due with respect
to its Loans and Letter of Credit Liabilities which is greater than the
proportion received by any other Bank in respect of the aggregate amount of
principal and interest due with respect to the Loans and Letter of Credit
Liabilities of such other Bank, the Bank receiving such proportionately greater
payment shall purchase such participations in the Loans and Letter of Credit
Liabilities of the other Banks, and such other adjustments shall be made, as may
be required so that all such payments of principal with respect to the Loans and
Letter of Credit Liabilities shall be shared by the Banks pro rata; provided
that nothing in this

                                       56

 
Section shall impair the right of any Bank to exercise any right of set-off or
counterclaim it may have and to apply the amount subject to such exercise to the
payment of indebtedness of any Obligor other than its indebtedness hereunder.
Each Obligor agrees, to the fullest extent it may effectively do so under
applicable law, that any holder of a participation in a Loan or Letter of Credit
Liability, whether or not acquired pursuant to the foregoing arrangements, may
exercise rights of set-off or counterclaim and other rights with respect to such
participation as fully as if such holder of a participation were a direct
creditor of such Obligor in the amount of such participation.

     (b)  Upon (i) the occurrence and during the continuance of any Event of
Default and (ii) the making of the request specified by Section 6.01 to
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Bank and each of its affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and otherwise apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at
any time owing by such Bank or such affiliate to or for the credit or the
account of any Obligor against any and all of the obligations of such Obligor to
such Bank now or hereafter existing under the Financing Documents, irrespective
of whether such Bank shall have made any demand for payment thereof and although
such obligations may be unmatured.  Each Bank agrees promptly to notify such
Obligor after any such setoff and application; provided, however, that the
failure to give such notice shall not affect the validity of such setoff and
application.  The rights of each Bank and its affiliates under this Section are
in addition to other rights and remedies (including, without limitation, other
rights of setoff) that such Bank and its affiliates may have.


     Section 10.05.  Amendments and Waivers.  Any provision of this Agreement or
the Notes may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the Obligors and the Required Banks (and, if the
rights or duties of the Administrative Agent or any Issuing Bank are affected
thereby, by it); provided that no such amendment or waiver shall, unless signed
by all the Banks, (i) increase or decrease the Commitment of any Bank (except
for a ratable decrease in the Commitments of all Banks) or subject any Bank to
any additional obligation, (ii) reduce the principal of or rate of interest on
any Loan or Letter of Credit Liabilities or any fees hereunder, (iii) postpone
the date fixed for any payment of principal of or interest on any Loan or the
amount to be reimbursed in respect of any Letter of Credit or interest thereon
or any fees hereunder or for any reduction or termination of any Commitments,
(iv) release any Guarantor hereunder, (v) change the percentage of the
Commitments or of the aggregate unpaid principal amount of the Loans and/or
Letter of Credit Liabilities, or the number of Banks, which shall be required
for

                                       57

 
the Banks or any of them to take any action under this Section or any other
provision of this Agreement or (vi) amend this Section 10.05.

     Section 10.06.  Successors and Assigns.

     (a)  The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns,
except that the Obligors may not assign or otherwise transfer any of their
rights under this Agreement without the prior written consent of all Banks.

     (b)  Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans.  In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Administrative Agent, such Bank shall remain responsible for
the performance of its obligations hereunder, and the Borrower, the Issuing
Banks and the Administrative Agent shall continue to deal solely and directly
with such Bank in connection with such Bank's rights and obligations under this
Agreement.  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 the 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 described in clause (i), (ii), (iii), (iv)
or (v) of Section 10.05 without the consent of the Participant.  The Borrower
agrees that each Participant shall, to the extent provided in its participation
agreement and subject to subsection (e) below, be entitled to the benefits of
Article 8 with respect to its participating interest.  An assignment or other
transfer which is not permitted by subsection (c) or (d) below shall be given
effect for purposes of this Agreement only to the extent of a participating
interest granted in accordance with this subsection (b).

     (c)  Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part (equivalent to an
initial participation in the Related Documents of not less than $15,000,000,
unless the Borrower shall otherwise consent or the assignment is for all of the
rights and obligations of the transferor Bank) of all, of its rights and
obligations under this Agreement and the Notes, and such Assignee shall assume
such rights and obligations, pursuant to an Assignment and Assumption Agreement
in substantially the form of Exhibit I hereto executed by such Assignee and such
transferor Bank, with (and subject to) the subscribed consent of the Borrower
and the Administration Agent, which shall not be unreasonably withheld, and the
Issuing Banks; provided that if an Assignee is an affiliate of such transferor
Bank 

                                       58

 
or was a Bank immediately prior to such assignment, no such consent of the
Borrower or the Administrative Agent shall be required; and provided further
that such assignment may, but need not, include rights of the transferor Bank in
respect of outstanding Money Market Loans; and provided further that, unless the
Borrower shall otherwise consent or the assignment is for all of the rights and
obligations of the transferor Bank, the participation in the Related Documents
of such transferor Bank after giving effect to such assignment (together with
the participations of its affiliates) shall not be less than $15,000,000; and
provided further that such assignment shall be accompanied by a ratably
equivalent assignment of the rights and obligations of the transferor Bank (and
its affiliates) under each of the other Related Documents.  Upon execution and
delivery of such instrument and payment by such Assignee to such transferor Bank
of an amount equal to the purchase price agreed between such transferor Bank and
such Assignee, such Assignee shall be a Bank party to this Agreement and shall
have all the rights and obligations of a Bank with a Commitment as set forth in
such instrument of assumption, and the transferor Bank shall be released from
its obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required.  Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Administrative Agent
and the Borrower shall make appropriate arrangements so that, if required, a new
Note is issued to the Assignee.  In connection with any such assignment, the
transferor Bank shall pay to the Administrative Agent an administrative fee for
processing such assignment in the amount of $2,500.

     (d)  Any Bank may at any time assign all or any portion of its rights under
this Agreement and its Note to a Federal Reserve Bank. No such assignment shall
release the transferor Bank from its obligations hereunder.

     (e)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring
such Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

     Section 10.07.  Collateral.  Each of the Banks represents to the
Administrative Agent and each of the other Banks that it in good faith is not
relying upon any "margin stock" (as defined in Regulation U) as collateral in
the extension or maintenance of the credit provided for in this Agreement.

     Section 10.08.  Governing Law.  This Agreement and each Note shall be
governed by and construed in accordance with the laws of the State of New York.

                                       59

 
     Section 10.09.  Counterparts; Integration; Effectiveness.  This Agreement
may be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same
instrument. This Agreement constitutes the entire agreement and understanding
among the parties hereto and supersedes any and all prior agreements and
understandings, oral or written, relating to the subject matter hereof. This
Agreement shall become effective upon receipt by the Administrative Agent of
counterparts hereof signed by each of the parties hereto (or, in the case of any
party as to which an executed counterpart shall not have been received, receipt
by the Administrative Agent in form satisfactory to it of telegraphic, telex,
facsimile or other written confirmation from such party of execution of a
counterpart hereof by such party).

     Section 10.10.  Judicial Proceedings.  (a) Consent to Jurisdiction. Each
Obligor irrevocably submits to the jurisdiction of any federal court sitting in
New York City and, in the event that jurisdiction cannot be obtained or
maintained in a federal court, to the jurisdiction of any New York State court
sitting in New York City over any suit, action or proceeding arising out of or
relating to any of the Financing Documents. Each Obligor 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 suit, action or proceeding brought
in such court and any claim that any suit, action or proceeding brought in such
a court has been brought in an inconvenient forum. Each Obligor agrees that a
final judgment in any such suit, action or proceeding brought in such a court
shall be conclusive and binding upon it and will be given effect in Bermuda or
the Cayman Islands, as the case may be, to the fullest extent permitted by
applicable law and may be enforced in any federal or New York State court
sitting in New York City (or any other courts to the jurisdiction of which such
Obligor is or may be subject) by a suit upon such judgment, provided that
service of process is effected upon it in one of the manners specified herein or
as otherwise permitted by law.

     (b)  Appointment of Agent for Service of Process.  Each Obligor hereby
irrevocably designates and appoints CT Corporation System having an office on
the date hereof at 1633 Broadway, New York, New York 10019 as its authorized
agent, to accept and acknowledge on its behalf, service of any and all process
which may be served in any suit, action or proceeding of the nature referred to
in subsection (a) above in any federal or New York State court sitting in New
York City.  Each Obligor represents and warrants that such agent has agreed in
writing to accept such appointment and that a true copy of such designation and
acceptance has been delivered to the Administrative Agent.  Said designation and
appointment shall be irrevocable until the Commitments shall have terminated and
all Letter of Credit Liabilities and all principal and interest and all other
amounts payable hereunder and under the Notes shall have been paid in full in

                                       60

 
accordance with the provisions hereof and thereof.  If such agent shall cease so
to act, each Obligor covenants and agrees to designate irrevocably and appoint
without delay another such agent satisfactory to the Administrative Agent and to
deliver promptly to the Administrative Agent evidence in writing of such other
agent's acceptance of such appointment.

     (c)  Service of Process.  Each Obligor hereby consents to process being
served in any suit, action or proceeding of the nature referred to in subsection
(a) above in any federal or New York State court sitting in New York City by
service of process upon the agent of such Obligor for service of process in such
jurisdiction appointed as provided in subsection (b) above; provided that, to
the extent lawful and possible, notice of said service upon such agent shall be
mailed by registered or certified air mail, postage prepaid, return receipt
requested, to such Obligor at its address specified on the signature page hereof
or to any other address of which such Obligor shall have given written notice to
the Bank.  Each Obligor irrevocably waives, to the fullest extent permitted by
law, all claim of error by reason of any such service in such manner and agrees
that such service shall be deemed in every respect effective service of process
upon such Obligor in any such suit, action or proceeding and shall, to the
fullest extent permitted by law, be taken and held to be valid and personal
service upon and personal delivery to such Obligor.

     (d)  No Limitation on Service or Suit.  Nothing in this Section 10.10 shall
affect the right of the Administrative Agent or any Bank to serve process in any
other manner permitted by law or limit the right of the Administrative Agent or
any Bank to bring proceedings against any Obligor in the courts of any
jurisdiction or jurisdictions.

     Section 10.11.  Judgment Currency.  If, under any applicable law and
whether pursuant to a judgment being made or registered against any Obligor or
for any other reason, any payment under or in connection with any of the
Financing Documents is made or satisfied in a currency (the "Other Currency")
other than that in which the relevant payment is due (the "Required Currency")
then, to the extent that the payment (when converted into the Required Currency
at the rate of exchange on the date of payment or, if it is not practicable for
the party entitled thereto (the "Payee") to purchase the Required Currency with
the Other Currency on the date of payment, at the rate of exchange as soon
thereafter as it is practicable for it to do so) actually received by the Payee
falls short of the amount due under the terms of this Agreement and the Notes,
each Obligor shall, to the extent permitted by law, as a separate and
independent obligation, indemnify and hold harmless the Payee against the amount
of such short-fall. For the purpose of this Section, "rate of exchange" means
the rate at which the Payee

                                       61

 
is able on the relevant date to purchase the Required Currency with the Other
Currency and shall take into account any premium and other costs of exchange.

     Section 10.12.  WAIVER OF JURY TRIAL.  EACH OF THE OBLIGORS, THE
ADMINISTRATIVE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

     Section 10.13.  Existing Credit Agreement.  On the Closing Date and
simultaneously with the closing the Borrower hereby gives notice to Morgan
Guaranty Trust Company of New York, as agent, under Section 2.09 of the Credit
Agreement referred to in clause (x) of Section 3.01 of the termination of the
Commitments (as defined therein) and the Banks hereby waive the requirement that
prior notice of such termination be given as therein provided.

     Section 10.14.  Confidentiality.  The Administrative Agent and each Bank
agrees to keep any information delivered or made available by any Obligor
pursuant to this Agreement confidential from anyone other than persons employed
or retained by such Bank and its affiliates who are engaged in evaluating,
approving, structuring or administering the credit facility contemplated hereby;
provided that nothing herein shall prevent any Bank from disclosing such
information (a) to any other Bank or to the Administrative Agent, (b) subject to
provisions substantially similar to those contained in this Section 10.14, to
any other Person if reasonably incidental to the administration of the credit
facility contemplated hereby, (c) upon the order of any court or administrative
agency, (d) upon the request or demand of any regulatory agency or authority,
(e) which had been publicly disclosed other than as a result of a disclosure by
the Administrative Agent or any Bank prohibited by this Agreement, (f) in
connection with any litigation relating to the Related Documents to which the
Administrative Agent, any Bank or its subsidiaries or Parent may be a party, (g)
to the extent necessary in connection with the exercise of any remedy hereunder,
(h) to such Bank's or Administrative Agent's legal counsel and independent
auditors and (i) subject to provisions substantially similar to those contained
in this Section 10.14, to any actual or proposed Participant or Assignee.
Notwithstanding the foregoing, this Section 10.14 shall not apply to information
that is or becomes publicly available, information that was available to a Bank
on a non-confidential basis prior to its disclosure hereunder and information
which becomes available to a Bank on a non-confidential basis from a source that
is not, to such Bank's knowledge, subject to a confidentiality agreement with
any Obligor.

                                       62

 
     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.
