Borrowing shall be in an aggregate amount of $5,000,000 or an integral multiple
of $1,000,000 in excess thereof (or, if less, an aggregate amount equal to the
amount by which the aggregate amount of a proposed Competitive Bid Borrowing
requested by the Borrower exceeds the aggregate amount of Competitive Bid
Advances offered to be made by the Lenders and accepted by the Borrower in
respect of such Competitive Bid Borrowing, if such Competitive Bid Borrowing is
made on the same date as such Revolving Credit Borrowing) and shall consist of
Revolving Credit Advances of the same Type made on the same day by the Lenders
ratably according to their respective Commitments. Within the limits of each
Lender's Commitment, the Borrower may borrow under this Section 2.01, prepay
pursuant to Section 2.10 and reborrow under this Section 2.01.

                  SECTION 2.02. Making the Revolving Credit Advances. (a) Each
Revolving Credit Borrowing shall be made on notice, given not later than 11:00
A.M. (New York City time) on the third Business Day prior to the date of the
proposed Revolving Credit Borrowing in the case of a Revolving Credit Borrowing
consisting of Eurodollar Rate Advances, or 9:00 A.M. (New York City time) the
Business Day of the proposed Revolving Credit Borrowing in the case of a
Revolving Credit Borrowing consisting of Base Rate Advances, by the Borrower to
the Agent, which shall give to each Lender prompt notice thereof by telecopier
or telex. Each such notice of a Revolving Credit Borrowing (a "Notice of
Revolving Credit Borrowing") shall be by telephone, confirmed immediately in
writing, or telecopier or telex in substantially the form of Exhibit B-1 hereto,
specifying therein the requested (i) date of such Revolving Credit Borrowing,
(ii) Type of Advances comprising such Revolving Credit Borrowing, (iii)
aggregate amount of such Revolving Credit Borrowing, and (iv) in the case of a
Revolving Credit Borrowing consisting of Eurodollar Rate Advances, initial
Interest Period for each such Revolving Credit Advance. Each Lender shall,
before 11:00 A.M. (New York City time) on the date of such Revolving Credit
Borrowing, make available for the account of its Applicable Lending Office to
the Agent at the Agent's Account, in same day funds, such Lender's ratable
portion of such Revolving Credit Borrowing. After the Agent's receipt of such
funds and upon fulfillment of the applicable conditions set forth in Article
III, the Agent will make such funds available to the Borrower at the Agent's
address referred to in Section 8.02.

         (b) Anything in subsection (a) above to the contrary notwithstanding,
(i) the Borrower may not select Eurodollar Rate Advances for any Revolving
Credit Borrowing if the aggregate amount of such Revolving Credit Borrowing is
less than $5,000,000 or if the obligation of the Lenders to make Eurodollar Rate
Advances shall then be suspended pursuant to Section 2.08 or 2.12 and (ii) the
Eurodollar Rate Advances may not be outstanding as part of more than ten
separate Revolving Credit Borrowings.
<PAGE>   18

         (c) Each Notice of Revolving Credit Borrowing shall be irrevocable and
binding on the Borrower. In the case of any Revolving Credit Borrowing that the
related Notice of Revolving Credit Borrowing specifies is to be comprised of
Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any
loss, cost or expense incurred by such Lender as a result of any failure to
fulfill on or before the date specified in such Notice of Revolving Credit
Borrowing for such Revolving Credit Borrowing the applicable conditions set
forth in Article III, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Revolving Credit Advance to be made by such Lender as part of such Revolving
Credit Borrowing when such Revolving Credit Advance, as a result of such
failure, is not made on such date.

         (d) Unless the Agent shall have received notice from a Lender prior to
the date of any Revolving Credit Borrowing that such Lender will not make
available to the Agent such Lender's ratable portion of such Revolving Credit
Borrowing, the Agent may assume that such Lender has made such portion available
to the Agent on the date of such Revolving Credit Borrowing in accordance with
subsection (a) of this Section 2.02 and the 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 Lender shall not have so made such ratable
portion available to the Agent, such Lender and the Borrower severally agree to
repay to the 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 Agent, at (i) in the
case of the Borrower, the interest rate applicable at the time to Revolving
Credit Advances comprising such Revolving Credit Borrowing and (ii) in the case
of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent
such corresponding amount, such amount so repaid shall constitute such Lender's
Revolving Credit Advance as part of such Revolving Credit Borrowing for purposes
of this Agreement.

         (e) The failure of any Lender to make the Revolving Credit Advance to
be made by it as part of any Revolving Credit Borrowing shall not relieve any
other Lender of its obligation, if any, hereunder to make its Revolving Credit
Advance on the date of such Revolving Credit Borrowing, but no Lender shall be
responsible for the failure of any other Lender to make the Revolving Credit
Advance to be made by such other Lender on the date of any Revolving Credit
Borrowing.

             SECTION 2.03. The Competitive Bid Advances. (a) Each Lender
severally agrees that the Borrower may make Competitive Bid Borrowings under
this Section 2.03 from time to time on any Business Day during the period from
the date hereof until the date occurring 30 days prior to the earlier of the
Revolver Termination Date and the Term Loan Conversion Date in the manner set
forth below; provided that, following the making of each Competitive Bid
Borrowing, the aggregate amount of the Advances then outstanding shall not
exceed the aggregate amount of the Commitments of the Lenders (computed without
regard to any Competitive Bid Reduction).

             (i) The Borrower may request a Competitive Bid Borrowing under
         this Section 2.03 by delivering to the Agent, by telecopier or telex, a
         notice of a Competitive Bid Borrowing (a "Notice of Competitive Bid
         Borrowing"), in substantially the form of Exhibit B-2 hereto,
         specifying therein the requested (v) date of such proposed Competitive
         Bid Borrowing, (w) aggregate amount of such proposed Competitive Bid
         Borrowing, (x) in the case of a Competitive Bid Borrowing consisting of
         LIBO Rate Advances, Interest Period, or in the case of a Competitive
         Bid Borrowing consisting of Fixed Rate Advances, maturity date for
         repayment of each Fixed Rate Advance to be made as part of such
         Competitive Bid Borrowing (which maturity date may not be earlier than
         the date occurring 7 days after the date of such Competitive Bid
         Borrowing or later than the earlier of (I) 180 days after the date of
         such Competitive Bid Borrowing and (II) the earlier of the Revolver
         Termination Date and the Term Loan Conversion Date), (y) interest
         payment date or dates relating thereto, and (z) other terms (if any) to
         be applicable to such Competitive Bid Borrowing, not later than 10:00
         A.M. (New York City time) (A) at least one Business Day prior to the
         date of the proposed Competitive Bid Borrowing, if the Borrower shall
         specify in the Notice of Competitive Bid Borrowing that the rates of
         interest to be offered by the Lenders shall be fixed rates per annum
         (the Advances comprising any such Competitive Bid Borrowing being
         referred to herein as "Fixed Rate Advances") and (B) at least five
         Business Days prior to the date of the proposed Competitive Bid
         Borrowing, if the Borrower shall instead specify in the Notice of
         
<PAGE>   19

         Competitive Bid Borrowing that the rates of interest be offered by the
         Lenders are to be based on the LIBO Rate (the Advances comprising such
         Competitive Bid Borrowing being referred to herein as "LIBO Rate
         Advances"). Each Notice of Competitive Bid Borrowing shall be
         irrevocable and binding on the Borrower. The Agent shall in turn
         promptly notify each Lender of each request for a Competitive Bid
         Borrowing received by it from the Borrower by sending such Lender a
         copy of the related Notice of Competitive Bid Borrowing.

                  (ii) Each Lender may, if, in its sole discretion, it elects to
         do so, irrevocably offer to make one or more Competitive Bid Advances
         to the Borrower as part of such proposed Competitive Bid Borrowing at a
         rate or rates of interest specified by such Lender in its sole
         discretion, by notifying the Agent (which shall give prompt notice
         thereof to the Borrower), before 9:30 A.M. (New York City time) on the
         date of such proposed Competitive Bid Borrowing, in the case of a
         Competitive Bid Borrowing consisting of Fixed Rate Advances and before
         10:00 A.M. (New York City time) three Business Days before the date of
         such proposed Competitive Bid Borrowing, in the case of a Competitive
         Bid Borrowing consisting of LIBO Rate Advances, of the minimum amount
         and maximum amount of each Competitive Bid Advance which such Lender
         would be willing to make as part of such proposed Competitive Bid
         Borrowing (which amounts may, subject to the proviso to the first
         sentence of this Section 2.03(a), exceed such Lender's Commitment, if
         any), the rate or rates of interest therefor and such Lender's
         Applicable Lending Office with respect to such Competitive Bid Advance;
         provided that if the Agent in its capacity as a Lender shall, in its
         sole discretion, elect to make any such offer, it shall notify the
         Borrower of such offer at least 30 minutes before the time and on the
         date on which notice of such election is to be given to the Agent by
         the other Lenders. If any Lender shall elect not to make such an offer,
         such Lender shall so notify the Agent, before 10:00 A.M. (New York City
         time) on the date on which notice of such election is to be given to
         the Agent by the other Lenders, and such Lender shall not be obligated
         to, and shall not, make any Competitive Bid Advance as part of such
         Competitive Bid Borrowing; provided that the failure by any Lender to
         give such notice shall not cause such Lender to be obligated to make
         any Competitive Bid Advance as part of such proposed Competitive Bid
         Borrowing.

                  (iii) The Borrower shall, in turn, before 10:30 A.M. (New York
         City time) on the date of such proposed Competitive Bid Borrowing, in
         the case of a Competitive Bid Borrowing consisting of Fixed Rate
         Advances and before 11:00 A.M. (New York City time) three Business Days
         before the date of such proposed Competitive Bid Borrowing, in the case
         of a Competitive Bid Borrowing consisting of LIBO Rate Advances,
         either:

                        (x) cancel such Competitive Bid Borrowing by giving the 
                  Agent notice to that effect, or

                        (y) accept one or more of the offers made by any Lender 
                  or Lenders pursuant to paragraph (ii) above, in its sole
                  discretion, by giving notice to the Agent of the amount of
                  each  Competitive Bid Advance (which amount shall be equal to
                  or greater than the minimum amount, and equal to or less than
                  the maximum amount, notified to the Borrower by the Agent on
                  behalf of such Lender for such Competitive Bid Advance
                  pursuant to paragraph (ii) above) to be made by each Lender
                  as part of such Competitive Bid Borrowing, and reject any
                  remaining offers made by Lenders pursuant to paragraph (ii)
                  above by giving the Agent notice to that effect. The Borrower
                  shall accept the offers made by any Lender or Lenders to make
                  Competitive Bid Advances in order of the lowest to the
                  highest rates of interest offered by such Lenders. If two or
                  more Lenders have offered the same interest rate, the amount
                  to be borrowed at such interest rate will be allocated among
                  such Lenders in proportion to the amount that each such
                  Lender offered at such interest rate.

                  (iv) If the Borrower notifies the Agent that such Competitive
         Bid Borrowing is cancelled pursuant to paragraph (iii)(x) above, the
         Agent shall give prompt notice thereof to the Lenders and such
         Competitive Bid Borrowing shall not be made.
<PAGE>   20
                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to paragraph (iii)(y) above, the Agent
         shall in turn promptly notify (A) each Lender that has made an offer as
         described in paragraph (ii) above, of the date and aggregate amount of
         such Competitive Bid Borrowing and whether or not any offer or offers
         made by such Lender pursuant to paragraph (ii) above have been accepted
         by the Borrower, (B) each Lender that is to make a Competitive Bid
         Advance as part of such Competitive Bid Borrowing, of the amount of
         each Competitive Bid Advance to be made by such Lender as part of such
         Competitive Bid Borrowing, and (C) each Lender that is to make a
         Competitive Bid Advance as part of such Competitive Bid Borrowing, upon
         receipt, that the Agent has received forms of documents appearing to
         fulfill the applicable conditions set forth in Article III. Each Lender
         that is to make a Competitive Bid Advance as part of such Competitive
         Bid Borrowing shall, before 12:00 noon (New York City time) on the date
         of such Competitive Bid Borrowing specified in the notice received from
         the Agent pursuant to clause (A) of the preceding sentence or any later
         time when such Lender shall have received notice from the Agent
         pursuant to clause (C) of the preceding sentence, make available for
         the account of its Applicable Lending Office to the Agent at the
         Agent's Account, in same day funds, such Lender's portion of such
         Competitive Bid Borrowing. Upon fulfillment of the applicable
         conditions set forth in Article III and after receipt by the Agent of
         such funds, the Agent will make such funds available to the Borrower at
         the Agent's address referred to in Section 8.02. Promptly after each
         Competitive Bid Borrowing the Agent will notify each Lender of the
         amount of the Competitive Bid Borrowing, the consequent Competitive Bid
         Reduction and the dates upon which such Competitive Bid Reduction
         commenced and will terminate.

                  (vi) If the Borrower notifies the Agent that it accepts one or
         more of the offers made by any Lender or Lenders pursuant to paragraph
         (iii)(y) above, such notice of acceptance shall be irrevocable and
         binding on the Borrower. The Borrower shall indemnify each Lender
         against any loss, cost or expense incurred by such Lender as a result
         of any failure to fulfill on or before the date specified in the
         related Notice of Competitive Bid Borrowing for such Competitive Bid
         Borrowing the applicable conditions set forth in Article III,
         including, without limitation, any loss (including loss of anticipated
         profits), cost or expense incurred by reason of the liquidation or
         reemployment of deposits or other funds acquired by such Lender to fund
         the Competitive Bid Advance to be made by such Lender as part of such
         Competitive Bid Borrowing when such Competitive Bid Advance, as a
         result of such failure, is not made on such date.

         (b) Each Competitive Bid Borrowing shall be in an aggregate amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof and,
following the making of each Competitive Bid Borrowing, the Borrower and each
Lender shall be in compliance with the limitations set forth in the proviso to
the first sentence of subsection (a) above.

         (c) Within the limits and on the conditions set forth in this Section
2.03, the Borrower may from time to time borrow under this Section 2.03, repay
or prepay pursuant to subsection (d) below, and reborrow under this Section
2.03, provided that a Competitive Bid Borrowing shall not be made within three
Business Days of the date of any other Competitive Bid Borrowing.

         (d) The Borrower shall repay to the Agent for the account of each
Lender that has made a Competitive Bid Advance, on the maturity date of each
Competitive Bid Advance (such maturity date being that specified by the Borrower
for repayment of such Competitive Bid Advance in the related Notice of
Competitive Bid Borrowing delivered pursuant to subsection (a)(i) above and
provided in the Competitive Bid Note evidencing such Competitive Bid Advance),
the then unpaid principal amount of such Competitive Bid Advance. The Borrower
shall have no right to prepay any principal amount of any Competitive Bid
Advance unless, and then only on the terms, specified by the Borrower for such
Competitive Bid Advance in the related Notice of Competitive Bid Borrowing
delivered pursuant to subsection (a)(i) above and set forth in the Competitive
Bid Note evidencing such Competitive Bid Advance.

         (e) The Borrower shall pay interest on the unpaid principal amount of
each Competitive Bid Advance from the date of such Competitive Bid Advance to
the date the principal amount of such Competitive Bid Advance is repaid in full,
at the rate of interest for such Competitive Bid Advance specified by the Lender
making 
<PAGE>   21

such Competitive Bid Advance in its notice with respect thereto delivered
pursuant to subsection (a)(ii) above, payable on the interest payment date or
dates specified by the Borrower for such Competitive Bid Advance in the related
Notice of Competitive Bid Borrowing delivered pursuant to subsection (a)(i)
above, as provided in the Competitive Bid Note evidencing such Competitive Bid
Advance. Upon the occurrence and during the continuance of an Event of Default,
the Borrower shall pay interest on the amount of unpaid principal of and
interest on each Competitive Bid Advance owing to a Lender, payable in arrears
on the date or dates interest is payable thereon, at a rate per annum equal at
all times to 2% per annum above the rate per annum required to be paid on such
Competitive Bid Advance under the terms of the Competitive Bid Note evidencing
such Competitive Bid Advance unless otherwise agreed in such Competitive Bid
Note.

         (f) The indebtedness of the Borrower resulting from each Competitive
Bid Advance made to the Borrower as part of a Competitive Bid Borrowing shall be
evidenced by a separate Competitive Bid Note of the Borrower payable to the
order of the Lender making such Competitive Bid Advance.

         (g) Upon delivery of each Notice of Competitive Bid Borrowing, the
Borrower shall pay a non-refundable fee of $3,000 to the Agent for its own
account.

             SECTION 2.04. Fees. (a) Facility Fee. The Borrower agrees to pay to
the Agent for the account of each Lender (other than the Designated Bidders) a
facility fee on the aggregate amount of such Lender's Commitment from the
Effective Date in the case of each Initial Lender and from effective date
specified in the Assignment and Acceptance pursuant to which it became a Lender
in the case of each other Lender until the Maturity Date at a rate per annum
equal to the Applicable Percentage in effect from time to time, payable in
arrears quarterly on the last day of each March, June, September and December,
commencing March 1998, and on the Maturity Date.

         (b) Agent's Fees. The Borrower shall pay to the Agent for its own
account such fees as may from time to time be agreed between the Borrower and
the Agent.

             SECTION 2.05. Termination or Reduction of the Commitments. (a) If
the Borrower has not made the Term Loan Election at least 15 days prior to the
Revolver Termination Date, the Commitments shall be automatically terminated on
the Revolver Termination Date. If the Borrower has made the Term Loan Election
in accordance with Section 2.06, from time to time after the Term Loan
Conversion Date upon each prepayment of the Revolving Credit Advances, the
aggregate Commitments of the Lenders under this Agreement shall be automatically
and permanently reduced on a pro rata basis by an amount equal to the amount by
which the aggregate Commitments of the Lenders under this Agreement immediately
prior to such reduction exceeds the aggregate unpaid principal amount of the
Revolving Credit Advances outstanding at such time.

         (b) The Borrower shall have the right, upon at least three Business
Days' notice to the Agent, to terminate in whole or reduce ratably in part the
unused portions of the respective Commitments of the Lenders, provided that each
partial reduction shall be in the aggregate amount of $5,000,000 or an integral
multiple of $1,000,000 in excess thereof and provided further that the aggregate
amount of the Commitments of the Lenders shall not be reduced to an amount that
is less than the aggregate principal amount of the Competitive Bid Advances then
outstanding.

             SECTION 2.06. Repayment of Revolving Credit Advances; Term Loan
Election. (a) The Borrower shall, subject to the next succeeding sentence, repay
to the Agent for the ratable account of the Lenders on the Revolver Termination
Date the aggregate principal amount of the Revolving Credit Advances then
outstanding.

         (b) The Borrower may, at any time prior to the Revolver Termination
Date and upon not less than 15 days' notice to the Agent, elect (the "Term Loan
Election") to convert all of the Revolving Credit Advances outstanding on the
date specified in such notice (the "Term Loan Conversion Date") into a term loan
which the Borrower shall repay in full to the Agent for the ratable account of
the Lenders on the Maturity Date; provided that no Default has occurred and is
continuing on the date of notice of the Term Loan Election or on the Term Loan
Conversion Date.
<PAGE>   22
                  SECTION 2.07. Interest on Revolving Credit Advances. (a)
Scheduled Interest. The Borrower shall pay interest on the unpaid principal
amount of each Revolving Credit Advance owing to each Lender from the date of
such Revolving Credit Advance until such principal amount shall be paid in full,
at the following rates per annum:

                  (i) Base Rate Advances. During such periods as such Revolving
         Credit Advance is a Base Rate Advance, a rate per annum equal at all
         times to the sum of (x) the Base Rate in effect from time to time plus
         (y) the Applicable Margin in effect from time to time, payable in
         arrears quarterly on the last day of each March, June, September and
         December during such periods and on the date such Base Rate Advance
         shall be Converted or paid in full.

                  (ii) Eurodollar Rate Advances. During such periods as such
         Revolving Credit Advance is a Eurodollar Rate Advance, a rate per annum
         equal at all times during each Interest Period for such Revolving
         Credit Advance to the sum of (x) the Eurodollar Rate for such Interest
         Period for such Revolving Credit Advance plus (y) the Applicable Margin
         in effect from time to time, payable in arrears on the last day of such
         Interest Period and, if such Interest Period has a duration of more
         than three months, on each day that occurs during such Interest Period
         every three months from the first day of such Interest Period and on
         the date such Eurodollar Rate Advance shall be Converted or paid in
         full.

         (b) Default Interest. Upon the occurrence and during the continuance of
an Event of Default, the Borrower shall pay interest on (i) the unpaid principal
amount of each Revolving Credit Advance owing to each Lender, payable in arrears
on the dates referred to in clause (a)(i) or (a)(ii) above, at a rate per annum
equal at all times to 2% per annum above the rate per annum required to be paid
on such Revolving Credit Advance pursuant to clause (a)(i) or (a)(ii) above and
(ii) to the fullest extent permitted by law, the amount of any interest, fee or
other amount payable hereunder that is not paid when due, from the date such
amount shall be due until such amount shall be paid in full, payable in arrears
on the date such amount shall be paid in full and on demand, at a rate per annum
equal at all times to 2% per annum above the rate per annum required to be paid
on Base Rate Advances pursuant to clause (a)(i) above.

                  SECTION 2.08. Interest Rate Determination. (a) Each Reference
Bank agrees to furnish to the Agent timely information for the purpose of
determining each Eurodollar Rate and each LIBO Rate. If any one or more of the
Reference Banks shall not furnish such timely information to the Agent for the
purpose of determining any such interest rate, the Agent shall determine such
interest rate on the basis of timely information furnished by the remaining
Reference Banks. The Agent shall give prompt notice to the Borrower and the
Lenders of the applicable interest rate determined by the Agent for purposes of
Section 2.07(a)(i) or (ii), and the rate, if any, furnished by each Reference
Bank for the purpose of determining the interest rate under Section 2.07(a)(ii).

         (b) If, with respect to any Eurodollar Rate Advances, the Required
Lenders notify the Agent that the Eurodollar Rate for any Interest Period for
such Advances will not adequately reflect the cost to such Required Lenders of
making, funding or maintaining their respective Eurodollar Rate Advances for
such Interest Period, the Agent shall forthwith so notify the Borrower and the
Lenders, whereupon (i) each Eurodollar Rate Advance will automatically, on the
last day of the then existing Interest Period therefor, Convert into a Base Rate
Advance, and (ii) the obligation of the Lenders to make, or to Convert Revolving
Credit Advances into, Eurodollar Rate Advances shall be suspended until the
Agent shall notify the Borrower and the Lenders that the circumstances causing
such suspension no longer exist.

         (c) If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advances in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the Agent will
forthwith so notify the Borrower and the Lenders and such Advances will
automatically, on the last day of the then existing Interest Period therefor,
Convert into Base Rate Advances.
<PAGE>   23
         (d) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment
or prepayment or otherwise, to less than $5,000,000, such Advances shall
automatically Convert into Base Rate Advances.

         (e) Upon the occurrence and during the continuance of any Event of
Default, (i) each Eurodollar Rate Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance and
(ii) the obligation of the Lenders to make, or to Convert Advances into,
Eurodollar Rate Advances shall be suspended.

         (f) If fewer than two Reference Banks furnish timely information to the
Agent for determining the Eurodollar Rate or LIBO Rate for any Eurodollar Rate
Advances or LIBO Rate Advances, as the case may be,

             (i) the Agent shall forthwith notify the Borrower and the Lenders
         that the interest rate cannot be determined for such Eurodollar Rate
         Advances or LIBO Rate Advances, as the case may be,

             (ii) with respect to Eurodollar Rate Advances, each such Advance
         will automatically, on the last day of the then existing Interest
         Period therefor, Convert into a Base Rate Advance (or if such Advance
         is then a Base Rate Advance, will continue as a Base Rate Advance), and

             (iii) the obligation of the Lenders to make Eurodollar Rate
         Advances or LIBO Rate Advances or to Convert Revolving Credit Advances
         into Eurodollar Rate Advances shall be suspended until the Agent shall
         notify the Borrower and the Lenders that the circumstances causing such
         suspension no longer exist.

             SECTION 2.09. Optional Conversion of Revolving Credit Advances. The
Borrower may on any Business Day, upon notice given to the Agent not later than
11:00 A.M. (New York City time) on the third Business Day prior to the date of
the proposed Conversion and subject to the provisions of Sections 2.08 and 2.12,
Convert all Revolving Credit Advances of one Type comprising the same Borrowing
into Revolving Credit Advances of the other Type; provided, however, that any
Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made
only on the last day of an Interest Period for such Eurodollar Rate Advances,
any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in
an amount not less than the minimum amount specified in Section 2.02(b) and no
Conversion of any Revolving Credit Advances shall result in more separate
Revolving Credit Borrowings than permitted under Section 2.02(b). Each such
notice of a Conversion shall, within the restrictions specified above, specify
(i) the date of such Conversion, (ii) the Revolving Credit Advances to be
Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the
duration of the initial Interest Period for each such Advance. Each notice of
Conversion shall be irrevocable and binding on the Borrower.

             SECTION 2.10. Prepayments of Revolving Credit Advances. (a)
Optional Prepayment. The Borrower may on any Business Day, upon notice given to
the Agent not later than 11:00 A.M., (i) on the same day for Base Rate Advances
and (ii) on the second Business Day prior to the prepayment in the case of
Eurodollar Rate Advances stating the proposed date and aggregate principal
amount of the prepayment, and if such notice is given the Borrower shall, prepay
the outstanding principal amount of the Revolving Credit Advances comprising
part of the same Revolving Credit Borrowing in whole or ratably in part,
together with accrued interest to the date of such prepayment on the principal
amount prepaid; provided, however, that (x) each partial prepayment shall be in
an aggregate principal amount of $5,000,000 or an integral multiple of
$1,000,000 in excess thereof and (y) in the event of any such prepayment of a
Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the
Lenders in respect thereof pursuant to Section 8.04(c).

             (b) Mandatory Prepayment. The Borrower shall, upon five Business
Days notice from the Agent given at the request or with the consent of the
Required Lenders, prepay the aggregate principal amount outstanding plus all
interest thereon and all other amounts payable hereunder or under the Notes, in
the event that (i) any Person or two or more Persons acting in concert shall
have acquired beneficial ownership (within the meaning of Rule 13d-3 of the
Securities and Exchange Commission under the Securities Exchange Act of 1934),
directly or indirectly, of Voting Stock of the Parent (or other securities
convertible into such Voting Stock) 
<PAGE>   24

representing 20% or more of the combined voting power of all Voting Stock of the
Parent; or (ii) any Person or two or more Persons acting in concert shall have
acquired by contract or otherwise, or shall have entered into a contract or
arrangement that, upon consummation, will result in its or their acquisition of
the power to exercise, directly or indirectly, a controlling influence over the
management or policies of the Parent.

             SECTION 2.11. Increased Costs. (a) If, due to either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances or LIBO Rate Advances
(excluding for purposes of this Section 2.11 any such increased costs resulting
from (i) Taxes or Other Taxes (as to which Section 2.14 shall govern) and (ii)
changes in the basis of taxation of overall net income or overall gross income
by the United States or by the foreign jurisdiction or state under the laws of
which such Lender is organized or has its Applicable Lending Office or any
political subdivision thereof), then the Borrower shall from time to time, upon
demand by such Lender (with a copy of such demand to the Agent), pay to the
Agent for the account of such Lender additional amounts sufficient to compensate
such Lender for such increased cost. A certificate as to the amount of such
increased cost, submitted to the Borrower and the Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error.

         (b) If any Lender determines that compliance with any law or regulation
or any guideline or request from any central bank or other governmental
authority (whether or not having the force of law) affects or would affect the
amount of capital required or expected to be maintained by such Lender or any
corporation controlling such Lender and that the amount of such capital is
increased by or based upon the existence of such Lender's commitment to lend
hereunder and other commitments of this type, then, upon demand by such Lender
(with a copy of such demand to the Agent), the Borrower shall pay to the Agent
for the account of such Lender, from time to time as specified by such Lender,
additional amounts sufficient to compensate such Lender or such corporation in
the light of such circumstances, to the extent that such Lender reasonably
determines such increase in capital to be allocable to the existence of such
Lender's commitment to lend hereunder. A certificate as to such amounts
submitted to the Borrower and the Agent by such Lender shall be conclusive and
binding for all purposes, absent manifest error.

         (c) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.11, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial institution shall be an Eligible Assignee and shall
assume the Commitments of such Lender and purchase the Notes held by such Lender
in accordance with Section 8.07, provided, however, that (i) no Default shall
have occurred and be continuing, (ii) the Borrower shall have satisfied all of
its obligations in connection with the Loan Documents with respect to such
Lender, and (iii) if such assignee is not a Lender, (A) such assignee is
acceptable to the Agent and (B) the Borrower shall have paid the Agent a $3,000
administrative fee.

             SECTION 2.12. Illegality. Notwithstanding any other provision
of this Agreement, if any Lender shall notify the Agent that the introduction of
or any change in or in the interpretation of any law or regulation makes it
unlawful, or any central bank or other governmental authority asserts that it is
unlawful, for any Lender or its Eurodollar Lending Office to perform its
obligations hereunder to make Eurodollar Rate Advances or LIBO Rate Advances or
to fund or maintain Eurodollar Rate Advances or LIBO Rate Advances hereunder,
(i) each Eurodollar Rate Advance or LIBO Rate Advance, as the case may be, will
automatically, upon such demand, Convert into a Base Rate Advance or an Advance
that bears interest at the rate set forth in Section 2.07(a)(i), as the case may
be, and (ii) the obligation of the Lenders to make Eurodollar Rate Advances or
LIBO Rate Advances or to Convert Revolving Credit Advances into Eurodollar Rate
Advances shall be suspended until the Agent shall notify the Borrower and the
Lenders that the circumstances causing such suspension no longer exist.

             SECTION 2.13. Payments and Computations. (a) The Borrower
shall make each payment hereunder and under the Notes not later than 11:00 A.M.
(New York City time) on the day when due in U.S. dollars to the Agent at the
Agent's Account in same day funds. The Agent will promptly thereafter cause to
be distributed like funds relating to the payment of principal or interest or
facility fees ratably (other than amounts 
<PAGE>   25

payable pursuant to Section 2.03, 2.11, 2.14 or 8.04(c)) to the Lenders for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Lender to such Lender for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(c), from and after the effective date
specified in such Assignment and Acceptance, the Agent shall make all payments
hereunder and under the Notes in respect of the interest assigned thereby to the
Lender assignee thereunder, and the parties to such Assignment and Acceptance
shall make all appropriate adjustments in such payments for periods prior to
such effective date directly between themselves.

         (b) The Borrower hereby authorizes each Lender, if and to the extent
payment owed to such Lender is not made when due hereunder or under the Note
held by such Lender, to charge from time to time against any or all of the
Borrower's accounts with such Lender any amount so due.

         (c) All computations of interest based on the Base Rate shall be made
by the Agent on the basis of a year of 365 or 366 days, as the case may be, and
all computations of interest based on the Eurodollar Rate or the Federal Funds
Rate and of facility fees shall be made by the Agent on the basis of a year of
360 days, in each case for the actual number of days (including the first day
but excluding the last day) occurring in the period for which such interest or
facility fees are payable. Each determination by the Agent of an interest rate
hereunder shall be conclusive and binding for all purposes, absent manifest
error.

         (d) Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or facility fee, as the case
may be; provided, however, that, if such extension would cause payment of
interest on or principal of Eurodollar Rate Advances or LIBO Rate Advances to be
made in the next following calendar month, such payment shall be made on the
next preceding Business Day.

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

             SECTION 2.14. Taxes. (a) Any and all payments by the Borrower
hereunder or under the Notes shall be made, in accordance with Section 2.13,
free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender and the Agent, taxes
imposed on its overall net income, and franchise taxes imposed on it in lieu of
net income taxes, by the jurisdiction under the laws of which such Lender or the
Agent (as the case may be) is organized or any political subdivision thereof
and, in the case of each Lender, taxes imposed on its overall net income, and
franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction
of such Lender's Applicable Lending Office or any political subdivision thereof
(all such non-excluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities in respect of payments hereunder or under the Notes being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder or under any
Note to any Lender or the Agent, (i) the sum payable shall be increased as may
be necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.14) such Lender or
the Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
law.
<PAGE>   26
         (b) In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or under the Notes or from the
execution, delivery or registration of, performing under, or otherwise with
respect to, this Agreement or the Notes (hereinafter referred to as "Other
Taxes").

         (c) The Borrower shall indemnify each Lender and the Agent for the full
amount of Taxes or Other Taxes (including, without limitation, any taxes imposed
by any jurisdiction on amounts payable under this Section 2.14) imposed on or
paid by such Lender or the Agent (as the case may be) and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto. This indemnification shall be made within 30 days from the date such
Lender or the Agent (as the case may be) makes written demand therefor.

         (d) Within 30 days after the date of any payment of Taxes, the Borrower
shall furnish to the Agent, at its address referred to in Section 8.02, the
original or a certified copy of a receipt evidencing payment thereof. In the
case of any payment hereunder or under the Notes by or on behalf of the Borrower
through an account or branch outside the United States or by or on behalf of the
Borrower by a payor that is not a United States person, if the Borrower
determines that no Taxes are payable in respect thereof, the Borrower shall
furnish, or shall cause such payor to furnish, to the Agent, at such address, an
opinion of counsel acceptable to the Agent stating that such payment is exempt
from Taxes. For purposes of this subsection (d) and subsection (e), the terms
"United States" and "United States person" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

         (e) Each Lender organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Initial Lender and on the date of the Assignment
and Acceptance pursuant to which it becomes a Lender in the case of each other
Lender, and from time to time thereafter as requested in writing by the Borrower
(but only so long as such Lender remains lawfully able to do so), shall provide
each of the Agent and the Borrower with two original Internal Revenue Service
forms 1001 or 4224, as appropriate, or any successor or other form prescribed by
the Internal Revenue Service, certifying that such Lender is exempt from or
entitled to a reduced rate of United States withholding tax on payments pursuant
to this Agreement or the Notes. If the forms provided by a Lender at the time
such Lender first becomes a party to this Agreement indicates a United States
interest withholding tax rate in excess of zero, withholding tax at such rate
shall be considered excluded from Taxes unless and until such Lender provides
the appropriate forms certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be considered excluded from Taxes
for periods governed by such form; provided, however, that, if at the date of
the Assignment and Acceptance pursuant to which a Lender assignee becomes a
party to this Agreement, the Lender assignor was entitled to payments under
subsection (a) in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term Taxes shall include
(in addition to withholding taxes that may be imposed in the future or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Lender assignee on such date. If any form or
document referred to in this subsection (e) requires the disclosure of
information, other than information necessary to compute the tax payable and
information required on the date hereof by Internal Revenue Service form 1001 or
4224, that the Lender reasonably considers to be confidential, the Lender shall
give notice thereof to the Borrower and shall not be obligated to include in
such form or document such confidential information.

         (f) For any period with respect to which a Lender has failed to provide
the Borrower with the appropriate form described in Section 2.14(e) (other than
if such failure is due to a change in law occurring subsequent to the date on
which a form originally was required to be provided, or if such form otherwise
is not required under the first sentence of subsection (e) above), such Lender
shall not be entitled to indemnification under Section 2.14(a) or (c) with
respect to Taxes imposed by the United States by reason of such failure;
provided, however, that should a Lender become subject to Taxes because of its
failure to deliver a form required hereunder, the Borrower shall take such steps
as the Lender shall reasonably request to assist the Lender to recover such
Taxes.

         (g) In the event that a Lender demands payment from the Borrower for
amounts owing pursuant to subsection (a) or (b) of this Section 2.14, the
Borrower may, upon payment of such amounts and subject to the requirements of
Sections 8.04 and 8.07, substitute for such Lender another financial
institution, which financial 
<PAGE>   27

institution shall be an Eligible Assignee and shall assume the Commitments of
such Lender and purchase the Notes held by such Lender in accordance with
Section 8.07, provided, however, that (i) no Default shall have occurred and be
continuing, (ii) the Borrower shall have satisfied all of its obligations in
connection with the Loan Documents with respect to such Lender, and (iii) if
such assignee is not a Lender, (A) such assignee is acceptable to the Agent and
(B) the Borrower shall have paid the Agent a $3,000 administrative fee.

                  SECTION 2.15. Sharing of Payments, Etc. If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the Revolving Credit Advances
owing to it (other than pursuant to Section 2.11, 2.14 or 8.04(c)) in excess of
its ratable share of payments on account of the Revolving Credit Advances
obtained by all the Lenders, such Lender shall forthwith purchase from the other
Lenders such participations in the Revolving Credit Advances owing to them as
shall be necessary to cause such purchasing Lender to share the excess payment
ratably with each of them; provided, however, that if all or any portion of such
excess payment is thereafter recovered from such purchasing Lender, such
purchase from each Lender shall be rescinded and such Lender shall repay to the
purchasing Lender the purchase price to the extent of such recovery together
with an amount equal to such Lender's ratable share (according to the proportion
of (i) the amount of such Lender's required repayment to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered.
The Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this Section 2.15 may, to the fullest extent permitted by
law, exercise all its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrower in the amount of such participation.

                  SECTION 2.16. Extensions of Revolver Termination Date. No
earlier than 45 days and no later than 30 days prior to the Revolver Termination
Date in effect at any time, the Borrower may, by written notice to the Agent,
request that such Revolver Termination Date be extended for a period of 364
days. Such request shall be irrevocable and binding upon the Borrower. The Agent
shall promptly notify each Lender of such request. If a Lender agrees, in its
individual and sole discretion, to so extend its Commitment (an "Extending
Lender"), it shall deliver to the Agent a written notice of its agreement to do
so no earlier than 30 days and no later than 20 days prior to such Revolver
Termination Date and the Agent shall notify the Borrower of such Extending
Lender's agreement to extend its Commitment no later than 15 days prior to such
Revolver Termination Date. The Commitment of any Lender that fails to accept or
respond to the Borrower's request for extension of the Revolver Termination Date
(a "Declining Lender") shall be terminated on the Revolver Termination Date
originally in effect (without regard to any extension by other Lenders) and on
such Revolver Termination Date the Borrower shall pay in full the principal
amount of all Advances owing to such Declining Lender, together with accrued
interest thereon to the date of such payment of principal and all other amounts
payable to such Declining Lender under this Agreement. The Agent shall promptly
notify each Extending Lender of the aggregate Commitments of the Declining
Lenders. The Extending Lenders, or any of them, may offer to increase their
respective Commitments by an aggregate amount up to the aggregate amount of the
Declining Lenders' Commitments and any such Extending Lender shall deliver to
the Agent a notice of its offer to so increase its Commitment no later than 15
days prior to such Revolver Termination Date. To the extent of any shortfall in
the aggregate amount of extended Commitments, the Borrower shall have the right
to require any Declining Lender to assign in full its rights and obligations
under this Agreement to an Eligible Assignee designated by the Borrower and
acceptable to the Agent, that agrees to accept all of such rights and
obligations (a "Replacement Lender"), provided that (i) such increase and/or
such assignment is otherwise in compliance with Section 8.07, (ii) such
Declining Lender receives payment in full of the principal amount of all
Advances owing to such Declining Lender, together with accrued interest thereon
to the date of such payment of principal and all other amounts payable to such
Declining Lender under this Agreement, and (iii) any such increase shall be
effective on the Revolver Termination Date in effect at the time the Borrower
requests such extension and any such assignment shall be effective on the date
specified by the Borrower and agreed to by the Replacement Lender and the Agent.
If Extending Lenders and Replacement Lenders provide Commitments in an aggregate
amount at least equal to 51% of the aggregate amount of the Commitments
outstanding 30 days prior to the Revolver Termination Date in effect at the time
the Borrower requests such extension, the Revolver Termination Date shall be
extended by 364 days for such Extending Lenders.
<PAGE>   28
                  SECTION 2.17. Use of Proceeds. The proceeds of the Advances
shall be available (and the Borrower agrees that it shall use such proceeds)
solely for general corporate purposes of the Borrower and its Subsidiaries.


                                   ARTICLE III

                     CONDITIONS TO EFFECTIVENESS AND LENDING

                  SECTION 3.01. Conditions Precedent to Effectiveness of
Sections 2.01 and 2.03. Sections 2.01 and 2.03 of this Agreement shall become
effective on and as of the first date (the "Effective Date") on which the
following conditions precedent have been satisfied:

                  (a) There shall have occurred no Material Adverse Change, in
         the case of the Parent and its Subsidiaries since December 31, 1996,
         and in the case of the Borrower, since the date of its formation.

                  (b) There shall exist no action, suit, investigation,
         litigation or proceeding affecting either Loan Party or any of its
         Subsidiaries pending or threatened before any court, governmental
         agency or arbitrator that (i) could be reasonably likely to have a
         Material Adverse Effect other than the matters described in the SEC
         Reports (the "Disclosed Litigation") or (ii) purports to affect the
         legality, validity or enforceability of any Loan Document or the
         consummation of the transactions contemplated hereby and there shall
         have been no adverse change in the status, or financial effect on any
         Loan Party or any of its Subsidiaries of the Disclosed Litigation from
         that described in the SEC Reports.

                  (c) Nothing shall have come to the attention of the Lenders
         during the course of their due diligence investigation to lead them to
         believe that the Information Memorandum was or has become misleading,
         incorrect or incomplete in any material respect; without limiting the
         generality of the foregoing, the Lenders shall have been given such
         access, as such Lenders have reasonably requested, to the management,
         records, books of account, contracts and properties of each Loan Party
         and its Subsidiaries as they shall have requested.

                  (d) All governmental and third party consents and approvals
         necessary in connection with the transactions contemplated hereby shall
         have been obtained (without the imposition of any conditions that are
         not acceptable to the Lenders) and shall remain in effect, and no law
         or regulation shall be applicable in the reasonable judgment of the
         Lenders that restrains, prevents or imposes materially adverse
         conditions upon the transactions contemplated by the Loan Documents.

                  (e) The Borrower shall have notified each Lender and the Agent
         in writing as to the proposed Effective Date.

                  (f) The Borrower shall have paid all accrued fees and expenses

                      (ii) No event has occurred and is continuing that
                  constitutes a Default.

                      (iii) The Parent shall have delivered a certificate,

         Date the following, each dated such day, in form and substance
         satisfactory to the Agent and (except for the Revolving Credit Notes)
         in sufficient copies for each Lender:

                      (i) The Revolving Credit Notes to the order of the
                  Lenders, respectively.

                  Directors of each Loan Party approving each Loan Document to

                  -necessary corporate action and governmental approvals, if
                  any, with respect to each Loan Document to which it is a
                  party.

                      (iii) A certificate of the Secretary or an Assistant
                  Secretary of each Loan Party certifying the names and true

         actions sought in such proceeding (including, without limitation, the
         entry of an order for relief against, or the appointment of a receiver,
         trustee, custodian or other similar official for, it or for any

                  SECTION 7.01. Authorization and Action. Each Lender hereby
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers and discretion under this Agreement as are delegated to
the Agent by the terms hereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Required Lenders, and such instructions shall be binding upon all Lenders
and all holders of Notes; provided, however, that the Agent shall not be
required to take any action that exposes the Agent to personal liability or that
is contrary to this Agreement or applicable law. The Agent agrees to give to
each Lender prompt notice of each notice given to it by the Borrower pursuant to
the terms of this Agreement.

                  SECTION 7.02. Agent's Reliance, Etc. Neither the Agent nor any
of its directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken by it or them under or in connection with this

Without 
<PAGE>   38

limitation of the generality of the foregoing, the Agent: (i) may treat
the payee of any Note as the holder thereof until the Agent receives and accepts
an Assignment and Acceptance entered into by the Lender that is the payee of
such Note, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 8.07; (ii) may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts; (iii)
makes no warranty or representation to any Lender and shall not be responsible
to any Lender for any statements, warranties or representations (whether written
or oral) made in or in connection with this Agreement; (iv) shall not have any

the terms, covenants or conditions of this Agreement on the part of the Borrower
or to inspect the property (including the books and records) of the Borrower;
(v) shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to
be created under or in connection with, any Loan Document or any other
instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopier,
telegram or telex) believed by it to be genuine and signed or sent by the proper
party or parties.

                  SECTION 7.03. Citibank and Affiliates. With respect to its
Commitment, the Advances made by it and the Note issued to it, Citibank shall
have the same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not the Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Citibank in its
individual capacity. Citibank and its Affiliates may accept deposits from, lend
money to, act as trustee under indentures of, accept investment banking
engagements from and generally engage in any kind of business with, the
Borrower, any of its Subsidiaries and any Person who may do business with or own
securities of the Borrower or any such Subsidiary, all as if Citibank were not
the Agent and without any duty to account therefor to the Lenders.

                  SECTION 7.04. Lender Credit Decision. Each Lender acknowledges
that it has, independently and without reliance upon the Agent or any other
Lender and based on the financial statements referred to in Section 4.01 and
such other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

                  SECTION 7.05. Indemnification. The Lenders (other than the
Designated Bidders) agree to indemnify the Agent (to the extent not reimbursed
by the Borrower), ratably according to the respective principal amounts of the
Revolving Credit Notes then held by each of them (or if no Revolving Credit
Notes are at the time outstanding or if any Revolving Credit Notes are held by
Persons that are not Lenders, ratably according to the respective amounts of
their Commitments), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by, or asserted against the Agent in any way relating to or arising out of any
Loan Document or any action taken or omitted by the Agent under any Loan
Document, provided that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Agent's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender (other than
the Designated Bidders) agrees to reimburse the Agent promptly upon demand for
its ratable share of any out-of-pocket expenses (including counsel fees)
incurred by the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, any Loan Document, to the extent that the
Agent is not reimbursed for such expenses by the Borrower.

                  SECTION 7.06. Successor Agent. The Agent may resign at any
time by giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Agent. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such 
<PAGE>   39

appointment, within 30 days after the retiring Agent's giving of notice of
resignation or the Required Lenders' removal of the retiring Agent, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which
shall be a commercial bank organized under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least $50,000,000. Upon the acceptance of any appointment as Agent hereunder by
a successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, discretion, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations under this Agreement. After any retiring Agent's resignation or
removal hereunder as Agent, the provisions of this Article VII shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement.

provision of this Agreement or the Revolving Credit Notes, nor consent to any
departure by the Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Required Lenders, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver

no amendment, waiver or consent shall, unless in writing and signed by the Agent
in addition to the Lenders required above to take such action, affect the rights
or duties of the Agent under this Agreement or any Note.

company or confirmed by telex answerback, respectively, except that notices and
communications to the Agent pursuant to Article II, III or VII shall not be
effective until received by the Agent. Delivery by telecopier of an executed
counterpart of any amendment or waiver of any provision of this Agreement or the
Notes or of any Exhibit hereto to be executed and delivered hereunder shall be
effective as delivery of a manually executed counterpart thereof.

                  SECTION 8.03. No Waiver; Remedies. No failure on the part of
any Lender or the Agent to exercise, and no delay in exercising, any right
hereunder or under any Note shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

                  SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to
pay on demand all reasonable costs and reasonable expenses of the Agent in
connection with the preparation, execution, delivery, administration,
modification and amendment of this Agreement, the Notes, each other Loan
Document and the 
<PAGE>   40

other documents to be delivered hereunder and thereunder, including, without
limitation, (A) all due diligence, syndication (including printing, distribution
and bank meetings), transportation, computer, duplication, appraisal,
consultant, and audit expenses and (B) the reasonable fees and reasonable
expenses of counsel for the Agent with respect thereto and with respect to
advising the Agent as to its rights and responsibilities under the Loan
Documents. The Borrower further agrees to pay on demand all reasonable costs and
reasonable expenses of the Agent and the Lenders, if any (including, without
limitation, reasonable internal and external counsel fees and expenses, provided
such fees and expenses are not duplicative), in connection with the enforcement
(whether through negotiations, legal proceedings or otherwise) of this
Agreement, the Notes and the other documents to be delivered hereunder,
including, without limitation, reasonable fees and expenses of counsel for the
Agent and each Lender in connection with the enforcement of rights under this
Section 8.04(a).

         (b) The Borrower agrees to indemnify, to the extent legally
permissible, and hold harmless the Agent and each Lender and each of their
Affiliates and their officers, directors, employees, agents and advisors (each,
an "Indemnified Party") from and against any and all claims, damages, losses,
liabilities and expenses (including, without limitation, reasonable fees and
expenses of counsel) that may be incurred by or asserted or awarded against any
Indemnified Party, in each case arising out of or in connection with or by
reason of, or in connection with the preparation for a defense of, any
investigation, litigation or proceeding arising out of, related to or in
connection with (i) the Notes, this Agreement, the other Loan Documents any of
the transactions contemplated herein or therein or the actual or proposed use of
the proceeds of the Advances or (ii) the actual or alleged presence of Hazardous
Materials on any property of the Borrower or any of its Subsidiaries or any
Environmental Action relating in any way to the Borrower or any of its
Subsidiaries, in each case whether or not such investigation, litigation or
proceeding is brought by the Borrower, its directors, shareholders or creditors
or an Indemnified Party or any other Person or any Indemnified Party is
otherwise a party thereto and whether or not the transactions contemplated
hereby are consummated, except to the extent such claim, damage, loss, liability
or expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence or
willful misconduct. The Borrower also agrees not to assert any claim against the
Agent, any Lender, any of their Affiliates, or any of their respective
directors, officers, employees, attorneys and agents, on any theory of
liability, for special, indirect, consequential or punitive damages arising out
of or otherwise relating to the Notes, this Agreement, the other Loan Documents
any of the transactions contemplated herein or therein or the actual or proposed
use of the proceeds of the Advances.

         (c) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance or LIBO Rate Advance is made by the Borrower to or for the account
of a Lender other than on the last day of the Interest Period for such Advance,
as a result of a payment or Conversion pursuant to Section 2.08(d) or (e), 2.10
or 2.12, acceleration of the maturity of the Notes pursuant to Section 6.01 or
for any other reason, the Borrower shall, upon demand by such Lender (with a
copy of such demand to the Agent), pay to the Agent for the account of such
Lender any amounts required to compensate such Lender for any additional losses,
costs or expenses that it may reasonably incur as a result of such payment or
Conversion, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Advance.

         (d) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of each Loan Party contained
in Sections 2.11, 2.14 and 8.04 shall survive the payment in full of principal,
interest and all other amounts payable hereunder and under the Notes.

             SECTION 8.05. Right of Set-off. Upon (i) the occurrence and
during the continuance of any Event of Default and (ii) the making of the
request or the granting of the consent specified by Section 6.01 to authorize
the Agent to declare the Notes due and payable pursuant to the provisions of
Section 6.01, each Lender 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 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
Lender or such Affiliate to or for the credit or the account of either Loan
Party against any and all of the obligations of either Loan Party now or
hereafter existing under the Loan Documents Agreement and the Note held by such
Lender, whether or not such Lender shall have made any demand under this
Agreement or such Note and although such obligations may be unmatured. Each
Lender agrees promptly to notify such Loan Party after any such set-off and
application, provided that the failure to give 
<PAGE>   41

such notice shall not affect the validity of such set-off and application. The
rights of each Lender and its Affiliates under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) that such Lender and its Affiliates may have.

                  SECTION 8.06. Binding Effect. This Agreement shall become
effective (other than Sections 2.01 and 2.03, which shall only become effective
upon satisfaction of the conditions precedent set forth in Section 3.01) when it
shall have been executed by the Borrower and the Agent and when the Agent shall
have been notified by each Initial Lender that such Initial Lender has executed
it and thereafter shall be binding upon and inure to the benefit of the
Borrower, the Agent and each Lender and their respective successors and assigns,
except that the Borrower shall not have the right to assign its rights hereunder
or any interest herein without the prior written consent of the Lenders.

                  SECTION 8.07. Assignments, Designations and Participations.
(a) Each Lender (other than the Designated Bidders) may assign to one or more
Persons all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Revolving Credit Advances owing to it and the Revolving Credit Note or Notes
held by it); provided, however, that (i) each such assignment shall be of a
constant, and not a varying, percentage of all rights and obligations under this
Agreement (other than any right to make Competitive Bid Advances, Competitive
Bid Advances owing to it and Competitive Bid Notes), (ii) except in the case of
an assignment to a Person that, immediately prior to such assignment, was a
Lender or an assignment of all of a Lender's rights and obligations under this
Agreement, the amount of the Commitment of the assigning Lender being assigned
pursuant to each such assignment (determined as of the date of the Assignment
and Acceptance with respect to such assignment) shall in no event be less than
$10,000,000 or an integral multiple of $1,000,000 in excess thereof, (iii) each
such assignment shall be to an Eligible Assignee, and (iv) the parties to each
such assignment shall execute and deliver to the Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with any
Revolving Credit Note subject to such assignment and a processing and
recordation fee of $3,000. Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each Assignment and
Acceptance, (x) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder and (y) the Lender assignor thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

         (b) By executing and delivering an Assignment and Acceptance, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such assignee confirms that it is an
Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers and discretion
under this Agreement as are delegated to the Agent by the terms hereof, together
with such powers and discretion as are reasonably incidental thereto; and (vii)
such assignee agrees that it will perform in accordance with their terms all of
the obligations that by the terms of this Agreement are required to be performed
by it as a Lender.

<PAGE>   42

         (c) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Revolving Credit Note or Notes subject to such assignment, the
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit C hereto, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower. Within five Business Days
after its receipt of such notice, the Borrower, at its own expense, shall
execute and deliver to the Agent in exchange for the surrendered Revolving
Credit Note a new Note to the order of such Eligible Assignee in an amount equal
to the Commitment assumed by it pursuant to such Assignment and Acceptance and,
if the assigning Lender has retained a Commitment hereunder, a new Revolving
Credit Note to the order of the assigning Lender in an amount equal to the
Commitment retained by it hereunder. Such new Revolving Credit Note or Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Revolving Credit Note or Notes, shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit A-1 hereto.

         (d) Each Lender (other than the Designated Bidders) may designate one
or more banks or other entities to have a right to make Competitive Bid Advances
as a Lender pursuant to Section 2.03; provided, however, that (i) no such Lender
shall be entitled to make more than two such designations, (ii) each such Lender
making one or more of such designations shall retain the right to make
Competitive Bid Advances as a Lender pursuant to Section 2.03, (iii) each such
designation shall be to a Designated Bidder and (iv) the parties to each such
designation shall execute and deliver to the Agent, for its acceptance and
recording in the Register, a Designation Agreement. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Designation Agreement, the designee thereunder shall be a party hereto
with a right to make Competitive Bid Advances as a Lender pursuant to Section
2.03 and the obligations related thereto.

         (e) By executing and delivering a Designation Agreement, the Lender
making the designation thereunder and its designee thereunder confirm and agree
with each other and the other parties hereto as follows: (i) such Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of, or the perfection or priority of any lien or security
interest created or purported to be created under or in connection with, this
Agreement or any other instrument or document furnished pursuant hereto; (ii)
such Lender makes no representation or warranty and assumes no responsibility
with respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under this Agreement or any
other instrument or document furnished pursuant hereto; (iii) such designee
confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Designation Agreement; (iv) such designee will,
independently and without reliance upon the Agent, such designating Lender or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such designee confirms that it is a
Designated Bidder; (vi) such designee appoints and authorizes the Agent to take
such action as agent on its behalf and to exercise such powers and discretion
under this Agreement as are delegated to the Agent by the terms hereof, together
with such powers and discretion as are reasonably incidental thereto; and (vii)
such designee agrees that it will perform in accordance with their terms all of
the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

         (f) Upon its receipt of a Designation Agreement executed by a
designating Lender and a designee representing that it is a Designated Bidder,
the Agent shall, if such Designation Agreement has been completed and is
substantially in the form of Exhibit D hereto, (i) accept such Designation
Agreement, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower.

         (g) The Agent shall maintain at its address referred to in Section 8.02
a copy of each Assignment and Acceptance and each Designation Agreement
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lenders and, with respect to Lenders other than Designated
Bidders, the Commitment of, and principal amount of the Advances owing to, each
Lender from time to time (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
<PAGE>   43

Borrower, the Agent and the Lenders may treat each Person whose name is recorded
in the Register as a Lender hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

         (h) Each Lender may sell participations to one or more banks or other
entities (other than the Borrower or any of its Affiliates) in or to all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitment, the Advances owing to it and the
Note or Notes held by it); provided, however, that (i) such Lender's obligations
under this Agreement (including, without limitation, its Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Note for all purposes of
this Agreement, (iv) the Borrower, the Agent and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement and (v) no participant
under any such participation shall have any right to approve any amendment or
waiver of any provision of this Agreement or any Note, or any consent to any
departure by the Borrower therefrom, except to the extent that such amendment,
waiver or consent would reduce the principal of, or interest on, the Notes or
any fees or other amounts payable hereunder, in each case to the extent subject
to such participation, or postpone any date fixed for any payment of principal
of, or interest on, the Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation.

         (i) Any Lender may, in connection with any assignment, designation or
participation or proposed assignment, designation or participation pursuant to
this Section 8.07, disclose to the assignee, designee or participant or proposed
assignee, designee or participant, any information relating to the Borrower
furnished to such Lender by or on behalf of the Borrower; provided that, prior
to any such disclosure, the assignee, designee or participant or proposed
assignee, designee or participant shall agree to preserve the confidentiality of
any Confidential Information relating to the Borrower received by it from such
Lender.

         (j) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time create a security interest in all or any portion of
its rights under this Agreement (including, without limitation, the Advances
owing to it and the Note or Notes held by it) in favor of any Federal Reserve
Bank in accordance with Regulation A of the Board of Governors of the Federal
Reserve System.

             SECTION 8.08. Confidentiality. Neither the Agent nor any Lender
shall disclose any Confidential Information to any other Person without the
consent of the Borrower, other than (a) to the Agent's or such Lender's
Affiliates and their officers, directors, employees, agents and advisors and, as
contemplated by Section 8.07(i), to actual or prospective assignees and
participants, and then only on a confidential basis, (b) as required by any law,
rule or regulation or judicial process, (c) to any rating agency when required
by it, provided that, prior to any such disclosure, such rating agency shall
undertake to preserve the confidentiality of any Confidential Information
relating to either Loan Party received by it from such Lender and (d) as
requested or required by any state, federal or foreign authority or examiner
regulating banks or banking.

             SECTION 8.09. Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.

             SECTION 8.10. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

             SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties hereto
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or federal court of
the United States of America sitting in New York City, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement or the Notes, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be heard and
determined in any such New York State 
<PAGE>   44

court or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that any party may otherwise have to bring any action or
proceeding relating to this Agreement or the Notes in the courts of any
jurisdiction.

         (b) Each of the parties hereto irrevocably and unconditionally waives,
to the fullest extent it may legally and effectively do so, any objection that
it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or the Notes in any New
York State or federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

             SECTION 8.12. Effective Date Assignments; Etc. (a) As of the
Effective Date, prior to giving effect to any assignment under this Agreement as
of such date, each Existing Lender party hereto represents and warrants, as to
the assignment effected by such Existing Lender by this Agreement that as of the
Effective Date (i) its Existing Commitment is in the dollar amount specified as
its Existing Commitment on Schedule II hereto and the aggregate outstanding
principal amount of Existing Advances owing to it is in the dollar amount
specified as the aggregate outstanding principal amount of Existing Advances
owing to such Existing Lender on Schedule II hereto; and (ii) that such Existing
Lender is the legal and beneficial owner of such interest being assigned by it
hereunder and that such interest is free and clear of any adverse claim created
by such Existing Lender.

             (b) Each Existing Lender party hereto and Initial Lender
confirms to, and agrees with, each of the other Initial Lenders as to the
assignment effected by this Agreement by such Existing Lender or Initial Lender,
as the case may be, as follows: (i) except as set forth in subsection (a) above,
each such Existing Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with the Original Credit Agreement or this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of the Original Credit Agreement or this Agreement or any other instrument
or document furnished pursuant thereto or hereto; (ii) each such Existing Lender
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of any Loan Party or any of its Subsidiaries or the
performance or observance by any Loan Party or any of its Subsidiaries of any of

other instrument or document furnished pursuant thereto or hereto; (iii) each
Initial Lender confirms that it has received such documents and information as
it has deemed appropriate to make its own credit analysis and decision to
execute and deliver this Agreement and agrees that it shall have no recourse
against the Agent, any Existing Lender or any other Lender with respect to any
matters relating to the Original Credit Agreement or this Agreement; and (iv)
each Initial Lender will, independently and without reliance upon the Agent, any
Existing Lender or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under this Agreement, the Note or Notes
held by it and the other documents executed in connection herewith.

             (c) As of the Effective Date, (i) each Initial Lender shall be
a party to this Agreement and, to the extent provided herein, have the rights
and obligations of a Lender hereunder and (ii) each Existing Lender party hereto
shall, to the extent provided herein, relinquish its rights and be released from
its obligations under this Agreement as to any assignment effected herein.

             (d) From and after the Effective Date, the Agent shall make
all payments under this Agreement in respect of the interest assigned hereby
(including, without limitation, all payments of principal, interest and
commitment fees with respect thereto) to the Initial Lenders and other Lenders

paid all accrued interest, fees and other amounts payable and owing to the
Existing Lenders and the Agent as of the Effective Date in connection with the
Original Credit Agreement. Without prejudice to the survival of any other

<PAGE>   45

actions of the Agent or any Lender in the negotiation, administration,
performance or enforcement thereof.

such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Credit Agreement; (iii) confirms that it is an Eligible Assignee; (iv)

after the Effective Date, the Agent shall make all payments under the Credit
Agreement and the Revolving Credit Notes in respect of the interest assigned
hereby (including, without limitation, all payments of principal, interest and
facility fees with respect thereto) to the Assignee. The Assignor and Assignee
shall make all appropriate adjustments in payments under the Credit Agreement
and the Revolving Credit Notes for periods prior to the Effective Date directly
between themselves.

                  7. This Assignment and Acceptance shall be governed by, and
construed in accordance with, the laws of the State of New York.

                  8. This Assignment and Acceptance may be executed in any

each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement. Delivery of an
executed counterpart of Schedule 1 to this Assignment and Acceptance by
