         The Revolving Credit Advances. Each Lender severally agrees, on the
terms and conditions hereinafter set forth, to make Revolving Credit Advances to
the Borrower from time to time on any Business Day during the period from the
Effective Date until the Termination Date in an aggregate amount not to exceed
at any time outstanding the amount set forth opposite such Lender's name on the
signature pages hereof or, if such Lender has entered into any Assignment and
Acceptance, set forth for such Lender in the Register maintained by the
Administrative Agent pursuant to Section 9.07(d), as such amount may be reduced
pursuant to Section 2.04 (such Lender's "Commitment"). Each Revolving Credit
Borrowing shall be in an aggregate amount of $1,000,000 or an integral multiple
of $1,000,000 in excess thereof 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 this Section 2.01, the Borrower may
borrow under this Section 2.01, prepay pursuant to Section 2.09, reborrow under
this Section 2.01 and may Convert Borrowings of one Type into Borrowings of
another Type as provided for in Section 2.08.

         Making the Revolving Credit Advances. c) Each Revolving Credit
Borrowing shall be made on notice, given not later than 11:00 A.M. (Atlantic
Standard 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 LIBOR Rate Advances or on 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 Administrative 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 hereto, specifying
therein the requested: (i) date of such Revolving Credit



<PAGE>   9


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 LIBOR Rate Advances, initial
Interest Period for each such Revolving Credit Advance. Each Lender shall,
before 12:00 noon (Atlantic Standard Time) on the date of such Revolving Credit
Borrowing, make available for the account of its Applicable Lending Office to
the Administrative Agent at the Administrative Agent's Account, in same day
funds, such Lender's ratable portion of such Revolving Credit Borrowing. After
the Administrative Agent's receipt of such funds and upon fulfillment of the
applicable conditions set forth in Article III, the Administrative Agent will
make such funds available to the Borrower at the Borrower's Account.

Anything in subsection (a) above to the contrary notwithstanding, the Borrower
may not select LIBOR Rate Advances for any Revolving Credit Borrowing if the
aggregate obligation of the Lenders to make LIBOR Rate Advances shall then be
suspended pursuant to Section 2.07 or 2.11.

Each Notice of Revolving Credit Borrowing shall be irrevocable and binding on
the Borrower. In the case of any Revolving Credit Borrowing consisting of LIBOR
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 (excluding 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.

Unless the Administrative Agent shall have received notice from a Lender prior
to the time of any Revolving Credit Borrowing that such Lender will not make
available to the Administrative Agent such Lender's ratable portion of such
Revolving Credit Borrowing, the Administrative Agent may assume that such Lender
has made such portion available to the Administrative Agent on the date of such
Revolving Credit Borrowing in accordance with subsection (a) of this Section
2.02 and the Administrative Agent may, in reliance upon such assumption, make
available to the Borrower on such date a corresponding amount. If and to the
extent that such Lender shall not have so made such ratable portion available to
the Administrative Agent, such Lender and the Borrower severally agree to repay
to the Administrative Agent forthwith on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent, at: (i) in the case of the Borrower, 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 Administrative 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 and the Borrower shall be relieved of its obligations to repay such
amount under this Section 2.02(d).

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 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.

         Facility Fee. The Borrower agrees to pay to the Administrative Agent
for the account of each Lender a facility fee on the aggregate amount of such
Lender's Commitment from the Effective Date until the Termination Date at a rate
per annum equal to 0.125%, payable quarterly in arrears on the last day of each
March, June, September and December, commencing on June 30, 2000, and on the
Termination Date.

         Termination or Reduction of the Commitments. (a) The Borrower shall
have the right, upon at least three Business Days' notice to the Administrative
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 $10,000,000 or an integral multiple of
$1,000,000 in excess thereof.

The aggregate amount of the Commitments shall be automatically reduced to zero
on the Termination Date. The Commitments once terminated or reduced may not be
reinstated.

         Repayment of Revolving Credit Advances. The Borrower shall repay to the
Administrative Agent for the ratable account of the Lenders on the Termination
Date the aggregate principal amount of the Revolving Credit Advances then
outstanding.


<PAGE>   10

         Interest. d) 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 Advance until such principal amount shall be paid in full,
at the following rates per annum:

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 Base Rate in
effect from time to time, payable in arrears on each Quarterly Date, and on the
date such Base Rate Advance shall be Converted or paid in full.

LIBOR Rate Advances: During such periods as such Revolving Credit Advance is a
LIBOR 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 LIBOR Rate for
such Interest Period for such Revolving Credit Advance, plus (y) the Applicable
Margin, 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 LIBOR Rate Advance shall be Converted or
paid in full.

Default Interest. Upon the occurrence and during the continuance of an Event of
Default under Section 6.01(a), 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 Revolving Credit Advances pursuant to clause (a)(i)
above.

         Interest Rate Determination. e) The Administrative Agent shall give
prompt notice to the Borrower and the Lenders of the applicable interest rate
determined by the Administrative Agent for purposes of Section 2.06(a)(i) or
(ii).

If, with respect to any LIBOR Rate Advances, the Required Lenders notify the
Administrative Agent that the LIBOR 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 LIBOR Rate Advances for such
Interest Period, the Administrative Agent shall forthwith so notify the Borrower
and the Lenders, whereupon: (i) each LIBOR 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, LIBOR Rate Advances shall be suspended until the
Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

If the Borrower shall fail to select the duration of any Interest Period for any
LIBOR Rate Advances in accordance with the provisions contained in the
definition of "Interest Period" in Section 1.01, the Administrative 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. On the date on which the aggregate unpaid
principal amount of LIBOR Rate Advances comprising any Borrowing shall be
reduced, by payment or prepayment or otherwise, to less than $1,000,000, such
Advances shall automatically Convert into Base Rate Advances.

Upon the occurrence and during the continuance of any Event of Default under
Section 6.01: (i) each LIBOR 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, continue or to Convert Advances
into, LIBOR Rate Advances shall be suspended.

If on any date the Administrative Agent is unable to determine the LIBOR Rate
for any LIBOR Rate Advances to be made on such date: the Administrative Agent
shall forthwith notify the Borrower and the Lenders that the interest rate
cannot be determined for such LIBOR Rate Advances, with respect to LIBOR 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
the obligation of the Lenders to make LIBOR Rate Advances or to Convert
Revolving Credit Advances into LIBOR



<PAGE>   11

Rate Advances shall be suspended until the Administrative Agent shall notify the
Borrower and the Lenders that the circumstances causing such suspension no
longer exist.

         Optional Conversion of Revolving Credit Advances. The Borrower may on
any Business Day, upon notice given to the Administrative Agent not later than
11:00 A.M. (Atlantic Standard 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 LIBOR Rate Advances into Base Rate Advances shall be made
only on the last day of an Interest Period for such LIBOR Rate Advances and any
Conversion of Base Rate Advances into LIBOR Rate Advances shall be in an amount
not less than $1,000,000. 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
LIBOR 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.

         Prepayments of Advances. The Borrower may, upon at least two Business
Days' notice to the Administrative Agent 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 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 $1,000,000 or an integral multiple of $1,000,000 in excess
thereof, and the Borrower shall be obligated to reimburse the Lenders in respect
thereof pursuant to Section 9.04(c).

         Increased Costs. f) 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 written 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 LIBOR Rate Advances (excluding for purposes of this Section 2.10 any
such increased costs resulting from: (i) Taxes or Other Taxes (as to which
Section 2.13 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 Administrative Agent), pay to the Administrative Agent for
the account of such Lender additional amounts sufficient to compensate such
Lender for such increased cost (whether or not such increased costs arise prior
to the receipt of written notification from such central bank or other
governmental authority); provided that the Borrower shall not be required to pay
any such increased costs to the extent such increased costs accrued prior to the
date that is six months prior to such notice. A certificate as to the amount of
such increased cost, submitted to the Borrower and the Administrative Agent by
such Lender, shall be conclusive and binding for all purposes, absent error in
the calculation of such amount.

If any Lender determines that compliance with any law or regulation or any
written 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 (excluding any reserves included in the
computation of the LIBOR Rate) 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 Administrative Agent), the Borrower shall pay to the
Administrative 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 (whether or not such amounts arise prior to the
receipt of written notification from such central bank or other governmental
authority) in the light of such circumstances, to the extent that such Lender
reasonably determines such increase in capital to be allocable (in the
proportion that such Lender's Commitment hereunder bears to all of such Lender's
commitments of this type) to the existence of such Lender's commitment to lend
hereunder; provided that the Borrower shall not be required to compensate such
Lender to the extent such amounts arose prior to the date that is six months
prior to such notice. A certificate as to such amounts submitted to the Borrower
and the Administrative Agent by such Lender shall be conclusive and binding for
all purposes, absent error in the calculation of such amounts.


<PAGE>   12

Any Lender claiming any additional amounts payable pursuant to this Section 2.10
agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to minimize such additional amounts and to change,
to the extent such Lender has at such time additional lending offices in
existence, the jurisdiction of its Applicable Lending Office if the making of
such a change would avoid the need for, or reduce the amount of, any additional
amounts that may thereafter accrue and would not, in the reasonable judgment of
such Lender, be otherwise notably disadvantageous to such Lender. The Borrower
shall reimburse such Lender for such Lender's reasonable expenses incurred in
connection with such change or in considering such a change in an amount not to
exceed the Borrower's pro rata share of such expenses based on such Lender's
Commitment and Advances and the total lending commitments and loans of such
Lender to its similarly situated customers.

         Illegality. Notwithstanding any other provision of this Agreement, if
any Lender shall notify the Administrative 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 having relevant jurisdiction
asserts that it is unlawful, for any Lender or its Applicable Office to perform
its obligations hereunder to make LIBOR Rate Advances or to fund or maintain
LIBOR Rate Advances hereunder: (i) each LIBOR Rate Advance made by such Lender
will automatically, upon such demand, Convert into a Base Rate Advance, as the
case may be; and (ii) the obligation of such Lender to make LIBOR Rate Advances
or to Convert Revolving Credit Advances into LIBOR Rate Advances shall be
suspended until the Administrative Agent shall notify the Borrower and the
Lenders that the circumstances causing such suspension no longer exist.

         Payments and Computations. g) The Borrower shall make each payment
hereunder and under the Notes not later than 11:00 A.M. (Atlantic Standard Time)
on the day when due in U.S. dollars to the Administrative Agent at the
Administrative Agent's Account in same day funds. The Administrative 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 payable
pursuant to Section 2.11 or 9.04(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. All computations of interest based on the Base Rate,
LIBOR Rate and of facility fees shall be made by the Administrative 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
Administrative Agent of an interest rate hereunder shall be conclusive and
binding for all purposes, absent error in the calculation of such interest rate.

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 LIBOR Rate Advances to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

Unless the Administrative Agent shall have received notice from the Borrower
prior to the time on which any payment is due to the Lenders hereunder that the
Borrower will not make such payment in full, the Administrative Agent may assume
that the Borrower has made such payment in full to the Administrative Agent on
such date and the Administrative Agent may, in reliance upon such assumption,
cause to be distributed to each 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 Administrative Agent, each Lender shall repay
to the Administrative 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
Administrative Agent, at the Federal Funds Rate.

         Taxes. h) Subject to subsections (e) and (f) below, any and all
payments by the Borrower hereunder or under the Notes shall be made, in
accordance with Section 2.12, 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 Administrative Agent, taxes imposed on its overall net
income, and franchise taxes imposed on it in lieu of net income taxes (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"). Subject to subsections (e) and (f) below,
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







<PAGE>   13

Administrative 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 2.13) such Lender or the
Administrative 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. Within 30 days after the date of any payment of Taxes, the
Borrower shall furnish to the Administrative Agent, at its address referred to
in Section 9.02, the original or a certified copy of a receipt evidencing
payment thereof.

In addition, the Borrower agrees to pay any 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 as a result of the introduction of or any change in or in the
interpretation of any law or regulation after the Effective Date (hereinafter
referred to as "Other Taxes").

Subject to subsections (d), (e) and (f) below, the Borrower shall indemnify each
Lender and the Administrative Agent for the full amount of Taxes or Other Taxes
(to the extent not previously paid under subsection (a) or (b) above) imposed on
or paid by such Lender or the Administrative Agent (as the case may be) and any
liability (including penalties, interest and expenses but excluding any taxes
imposed by any jurisdiction on amounts payable under this Section 2.13) arising
therefrom or with respect thereto. This indemnification shall be made within 30
days from the date such Lender or the Administrative Agent (as the case may be)
makes written demand therefor.

Notwithstanding anything else contained in this Section 2.13, the Borrower shall
only be required to pay additional sums with respect to Taxes, to a Lender (or
the Administrative Agent, as the case may be) pursuant to subsection (a), (b) or
(c) above if the obligation to pay such Taxes results from such Lender being
subject to any Taxes as a result of: (i) any amendment to the laws (or any
regulations thereunder), or any amendment to, or change in, an interpretation or
application of any such laws or regulations by any legislative body, court,
governmental agency or regulatory authority adopted or enacted after the date
hereof (or in the case of an entity that becomes a Lender after the date hereof,
the date such entity becomes a Lender); (ii) an amendment, modification or
revocation of any existing applicable tax treaty ratified, enacted or amended
after the date hereof (or in the case of an entity that becomes a Lender after
the date hereof, the date such entity becomes a Lender); or (iii) the
ratification of a new tax treaty ratified after the date hereof (or in the case
of an entity that becomes a Lender after the date hereof, the date such entity
becomes a Lender).

In the event that the Borrower makes an additional payment under Section 2.13(a)
or 2.13(c) for the account of any Lender and such Lender, in its sole opinion,
determines that it has finally and irrevocably received or been granted a credit
against, or relief or remission from, or repayment of, any tax paid or payable
by it in respect of or calculated with reference to the deduction or withholding
giving rise to such additional payment, such Lender shall, to the extent that it
determines that it can do so without prejudice to the retention of the amount of
such credit, relief, remission or repayment, pay to the Borrower such amount as
such Lender shall, in its sole opinion, have determined is attributable to such
deduction or withholding and will leave such Lender (after such payment) in no
worse position than it would have been had the Borrower not been required to
make such deduction or withholding. Nothing contained herein shall: (i)
interfere with the right of a Lender to arrange its tax affairs in whatever
manner it thinks fit; or (ii) oblige any Lender to claim any tax credit or to
disclose any information relating to its tax affairs or any computations in
respect thereof; or (iii) require any Lender to take or refrain from taking any
action that would prejudice its ability to benefit from any other credits,
reliefs, remissions or repayments to which it may be entitled. Each Lender and
the Administrative Agent shall reasonably cooperate with the Borrower at the
Borrower's written request and sole expense, in contesting any Taxes or Other
Taxes the Borrower would bear pursuant to this Section 2.13, provided, however,
that: (i) no tax return of such Lender or the Administrative Agent is or would
be held open as a result of such contest; (ii) neither such Lender nor the
Administrative Agent is required to reopen a tax year that has already closed;
and (iii) such Lender and the Administrative Agent shall, in the sole opinion of
such Lender and the Administrative Agent, respectively, have determined that
such contest will leave such Lender and the Administrative Agent, respectively,
in no worse position than it would have been in had it not contested such Taxes
or Other Taxes. Nothing contained herein shall interfere with the right of a
Lender or the Administrative Agent to arrange its tax affairs in whatever manner
it thinks fit, if in the sole judgment of such Lender or the Administrative
Agent, such contest would be disadvantageous to such Lender or the
Administrative Agent. In pursuing a contest in the Lender's or the
Administrative Agent's name, such Lender or the Administrative Agent will be
represented by counsel of such Lender's or the Administrative Agent's choice,
and will defend against, settle or otherwise control the contest and will not
relinquish control or decision making over the contest.


<PAGE>   14

Any Lender claiming any additional amounts payable pursuant to this Section 2.13
agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to minimize such additional amounts and to change,
to the extent such Lender has at such time additional lending offices in
existence, its Applicable Lending Office, if the making of such a change would
avoid the need for, or reduce the amount of, any additional amounts that may
thereafter accrue and would not, in the reasonable judgment of such Lender, be
otherwise notably disadvantageous to such Lender. The Borrower shall reimburse
such Lender for such Lender's reasonable expenses incurred in connection with
such change or in considering such a change in an amount not to exceed the
Borrower's pro rata share of such expenses based on such Lender's Commitment and
Advances to the Borrower and the total lending commitments and loans of such
Lender to its similarly situated customers.

         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 2.10, 2.13, 9.01(b), 9.04(c) or 9.07) 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 by
delivering payment pursuant to this Section 2.14 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.

         Use of Proceeds. The proceeds of the Advances shall be available (and
the Borrower agrees that it shall use such proceeds) solely for working capital
and general corporate purposes of the Borrower and its Subsidiaries, provided
that such proceeds shall not be used for the purpose of purchasing or carrying
margin stock (within the meaning of Regulation U issued by the Board of
Governors of the Federal Reserve System).

result in the creation or imposition of any Lien upon any Property of the
Borrower or any of its Subsidiaries pursuant to the terms of any agreement or

This Agreement has been, and each of the Notes when delivered hereunder will
have been, duly executed and delivered by the Borrower. This Agreement has been
duly executed and delivered by each Guarantor. Assuming that this Agreement has

Neither the Borrower nor any of its Subsidiaries is an Investment Company, as
such term is defined in the Investment Company Act of 1940, as amended.

No Loan Party is engaged in the business of extending credit for the purpose of

to others for the purpose of purchasing or carrying any margin stock.

Each of the Loan Parties has obtained all environmental, health and safety
permits, licenses and other authorizations required under all Environmental Laws

each of the Borrower and its Subsidiaries is in compliance with the terms and
conditions thereof, and is



<PAGE>   17

standards, prohibitions, requirements, obligations, schedules and timetables
contained in any applicable Environmental Law or in any regulation, code, plan,
order, decree, judgment, injunction, notice or demand letter issued, entered,
promulgated or approved thereunder, except to the extent failure to comply
therewith would not (either individually or in the aggregate) have a Material
Adverse Effect.

2000 compliance of its computer systems and equipment so that the Year 2000

obligations of the Loan Parties hereunder and under the Notes, and the
obligations of the Loan Parties under the Citibank Indebtedness are of equal
priority (pari passu); and (ii) except for any rights to set-off in favor of the
agent(s) or the lenders under Section 9.05 of the Five-Year Credit Agreement (as
described in the definition of Citibank Indebtedness), no Lien over any Property
of the Loan Parties has been granted in favor of the lenders party to such
agreement, as security for the obligations of the Borrower and its Subsidiaries
under the Citibank Indebtedness.

No Agency Relationship. The Borrower understands and agrees that neither the
Administrative Agent nor any Lender is the agent or representative of the
Borrower, and this Agreement shall not be construed to make the Administrative

Borrower or any of its Subsidiaries in connection with the operation and
administration of their respective businesses.

likely to incur, liability that would have a Material Adverse Effect as a result
of one or more of the following: (i) the occurrence of any ERISA Event; (ii) the
partial or complete withdrawal of such Loan Party or its ERISA Affiliates from a
Multiemployer Plan; or (iii) the reorganization or termination of a
Multiemployer Plan; then, and in any such event, the Administrative Agent: (i)
shall at the request, or may with the consent, of the Required Lenders, by
notice to the Borrower, declare the obligation of each Lender to make Advances
to be terminated, whereupon the same shall forthwith terminate; and (ii) shall
at the request, or may with the consent, of the Required Lenders, by notice to
the Borrower, declare the Notes, all interest thereon and all other amounts
payable under this Agreement to be forthwith due and payable, whereupon the
Notes, all such interest and all such amounts shall become and be forthwith due
and payable, without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Borrower; provided, however,
that in the event of an actual or deemed entry of an order for relief with
respect to the Borrower under the Federal Bankruptcy Code: (A) the obligation of
each Lender to make Advances shall automatically be terminated; and (B) the
Notes, all such interest and all such amounts shall automatically become and be
due and payable, without presentment, demand, protest or any notice of any kind,
all of which are hereby expressly waived by the Borrower.

GUARANTY

         Guaranty; Limitation of Liability. i) Each Guarantor hereby
unconditionally and irrevocably, jointly and severally ("in solidum") guarantees
the punctual payment when due, whether at stated maturity, by acceleration or
otherwise, of all obligations of each other Loan Party now or hereafter existing
under this Agreement or any Note, whether for principal, interest, fees,
expenses or otherwise (such obligations, to the extent not paid by such Loan
Party or specifically waived in accordance with Section 9.01, being the
"Guaranteed Obligations"), and agrees to pay any and all expenses (including
reasonable counsel fees and expenses) incurred by the Administrative Agent or
the Lenders in enforcing any rights under this Article VII ("this Guaranty").
Without limiting the generality of the foregoing, each Guarantor's liability
shall extend to all amounts that constitute part of the Guaranteed Obligations
and would be owed by any Loan Party to the Administrative Agent or any Lender
under this Agreement or any Note but for the fact that they are unenforceable or
not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving such Loan Party. j) Each Guarantor and, by its acceptance
of this Guaranty, the Administrative Agent and each other Lender, hereby
confirms that it is the intention of all such parties that this Guaranty not
constitute a fraudulent transfer or fraudulent conveyance for purposes of
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar Federal, state or Commonwealth of Puerto Rico law to
the extent applicable to this Guaranty. To effectuate the foregoing intention,
the Administrative Agent, each other Lender and each Guarantor hereby
irrevocably agrees that, notwithstanding the fact that this is a joint and
several Guaranty, the obligations of each Guarantor under this Guaranty shall
not exceed the greater of (A) the benefit realized by such Guarantor from the
proceeds of the Advances made from time to time by the Borrower to such
Guarantor; and (B) the maximum amount that will, after giving effect to such
maximum amount and all other probable contingent and fixed liabilities of such
Guarantor that are relevant under applicable law, and after giving effect to any
collections from, rights to receive contribution from, or payments made by or on
behalf of the other Guarantor in respect of the obligations of such other
Guarantor under this Guaranty, result in the obligations of such Guarantor under
this Guaranty not constituting a fraudulent transfer or fraudulent conveyance.
For purposes hereof, "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal, state or Commonwealth of Puerto Rico law for the relief of
debtors.

Each Guarantor agrees that in the event any payment shall be required to be made
to the Lenders under this Guaranty, such Guarantor will contribute, to the
maximum extent such that the contribution will not result in a fraudulent
transfer or fraudulent conveyance, such amounts to the other Guarantor so as to
maximize the aggregate amount paid to the Lenders under this Agreement and the
Notes.


<PAGE>   23

This is a guaranty of payment and not of collection, and is the primary
obligation of each of the Guarantors; and the Administrative Agent or any Lender
may, subject to the terms and conditions hereof, enforce this Guaranty against
either Guarantor without any prior enforcement of the Guaranteed Obligations
against the Borrower or the other Guarantor, and/or without any prior
enforcement of any other collateral security held by the Administrative Agent or
the Lenders as security for the payment and performance of the Borrower's
obligations to the Administrative Agent and/or the Lenders.

         Guaranty Absolute. Each Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of this Agreement
and the Notes, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Administrative Agent or the Lenders with respect thereto. The obligations of
each Guarantor under this Guaranty are independent of the Guaranteed
Obligations, and a separate action or actions may be brought and prosecuted
against such Guarantor to enforce this Guaranty, irrespective of whether any
action is brought against the Borrower or the other Guarantor or whether the
Borrower or the other Guarantor is joined in any such action or actions. The
liability of each Guarantor under this Guaranty shall be irrevocable, absolute
and unconditional irrespective of, and, to the maximum extent permitted by law,
each Guarantor hereby irrevocably waives, any defenses it may now or hereafter
have in any way relating to, any or all of the following:

any lack of validity or enforceability of this Agreement, the Notes or any
agreement or instrument relating hereto; any change in the time, manner or place
of payment of, or in any other term of, all or any of the Guaranteed
Obligations, or any other amendment or waiver of or any consent to departure
from this Agreement or any Note, including, without limitation, any increase in
the Guaranteed Obligations resulting from the extension of additional credit to
the Borrower or otherwise; any taking, exchange, release or non-perfection of
any collateral, or any taking, release or amendment or waiver of or consent to
departure from any other guaranty, for all or any of the Guaranteed Obligations;
any change, restructuring or termination of the corporate structure or existence
of the Borrower; or any other circumstance (including, without limitation, any
statute of limitations) or any existence of or reliance on any representation by
the Administrative Agent or any Lender that might otherwise constitute a defense
available to, or a discharge of, any Guarantor, the Borrower or any other
guarantor or surety other than payment when due.

This Guaranty shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by the Administrative Agent or any Lender upon the
insolvency, bankruptcy or reorganization of the Borrower or either Guarantor or
otherwise, all as though such payment had not been made.

         Waiver. k) Each Guarantor hereby waives the right to require
application (excusion de bienes) in respect of the Property of the Borrower or
the other Guarantor, promptness, diligence, notice of acceptance and any other
notice with respect to any of the Guaranteed Obligations and this Guaranty and
any requirement that the Administrative Agent or any Lender exhaust any right or
take any action against the Borrower or any other Person or any collateral. Each
Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated herein and that the waiver set forth in
this Section 7.03 is knowingly made in contemplation of such benefits. Each
Guarantor hereby waives any right to revoke this Guaranty, and acknowledges that
this Guaranty is continuing in nature and applies to all Guaranteed Obligations,
whether existing now or in the future.

So far as each of the Guarantors is concerned, the Lenders or the Administrative
Agent for the benefit of the Lenders, may, at any time and from time to time,
without the consent of or notice to the Guarantors, and without impairing or
releasing any of the obligations of the Guarantors hereunder, upon or without
any terms or conditions and in whole or in part:

exercise or refrain from exercising any rights against the Borrower or others
(including, without limitation, any other guarantor of payment of the Guaranteed
Obligations) or otherwise act or refrain from acting, whether under the Credit
Agreement or under rights and remedies that the Lenders may now or hereafter
have under any collateral given thereunder or henceforth; and when making any
demand hereunder against either or both the Guarantors, the Lenders or the
Administrative Agent for the benefit of the Lenders, may, but shall be under no
obligation to, make a similar demand on any other guarantor of payment of the
Guaranteed Obligations, and any failure by the Lenders or the Administrative
Agent to make any such demand or to collect any payments from any other
guarantor or any



<PAGE>   24

release of another guarantor of payment of the Guaranteed Obligations shall not
relieve the Guarantors of their obligations and liabilities hereunder, and shall
not release, impair or affect the rights and remedies, express or implied, or as
a matter of law, of the Lenders against the Guarantors (for the purposes hereof,
"demand" shall include the commencement and continuation of any legal
proceedings);

settle or compromise any of the Guaranteed Obligations, any security therefor or
any liability (including any of those hereunder) incurred directly or indirectly
in respect thereof or hereof, and subordinate the payment of all or any part
thereof to the payment of any liability (whether due or not) of the Borrower to
creditors of the Borrower other than the Lenders;

apply any sums by whomsoever paid or howsoever realized to any liability or
liabilities of the Borrower hereunder to the Administrative Agent and/or the
Lenders, regardless of what liability or liabilities of the Borrower remain
unpaid; and

amend or otherwise modify, consent to or waive any breach of, or any act,
omission or Default under, this Agreement and the Notes or any other agreements,
instruments or documents referred to therein or executed and delivered pursuant
thereto or in connection therewith, and this Guaranty shall apply to the
Guaranteed Obligations as set forth in each of such documents as so amended and
modified. Any such action taken by the Administrative Agent or the Lenders shall
not impair or release any of the obligations of the Guarantors hereunder.

         Continuing Guaranty; Assignments. This Guaranty is a continuing
guaranty and shall: (a) remain in full force and effect until the later of the
cash payment in full of the Guaranteed Obligations and all other amounts payable
under this Guaranty and the Termination Date; (b) be binding upon each
Guarantor, its successors and assigns; and (c) inure to the benefit of and be
enforceable by the Lenders, the Administrative Agent and their successors,
transferees and assigns. Without limiting the generality of the foregoing clause
(c), any Lender may assign or otherwise transfer all or any portion of its
rights and obligations hereunder (including, without limitation, all or any
portion of its Commitment, the Advances owing to it and the Note or Notes held
by it) to any other Person, and such other Person shall thereupon become vested
with all the benefits in respect thereof granted to such Lender herein or
otherwise, in each case as provided in Section 9.07.

         Subrogation. Neither Guarantor will exercise any rights that it may now
or hereafter acquire against the Borrower or any other insider guarantor that
arise from the existence, payment, performance or enforcement of such
Guarantor's obligations under this Guaranty, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution or
indemnification and any right to participate in any claim or remedy of the
Administrative Agent or any Lender against the Borrower, the other Guarantor or
any other insider guarantor or any collateral, whether or not such claim, remedy
or right arises in equity or under contract, statute or common law, including,
without limitation, the right to take or receive from the Borrower, the other
Guarantor or any other insider guarantor, directly or indirectly, in cash or
other Property or by set-off or in any other manner, payment or security solely
on account of such claim, remedy or right, unless and until all of the
Guaranteed Obligations and all other amounts payable under this Guaranty shall
have been paid in full in cash and the Termination Date shall have occurred. If
any amount shall be paid to either Guarantor in violation of the preceding
sentence at any time prior to the later of the payment in full in cash of the
Guaranteed Obligations and all other amounts payable under this Guaranty and the
Termination Date, such amount shall be held in trust for the benefit of the
Administrative Agent and the Lenders and shall forthwith be paid to the
Administrative Agent to be credited and applied to the Guaranteed Obligations
and all other amounts payable under this Guaranty, whether matured or unmatured,
in accordance with the terms of this Guaranty, or to be held as collateral for
any Guaranteed Obligations or other amounts payable under this Guaranty
thereafter arising. If: (i) either Guarantor shall make payment to the
Administrative Agent or any Lender of all or any part of the Guaranteed
Obligations; (ii) all of the Guaranteed Obligations and all other amounts
payable under this Guaranty shall be paid in full in cash; and (iii) the
Termination Date shall have occurred, the Administrative Agent and the Lenders
will, at such Guarantor's request and expense, execute and deliver to such
Guarantor appropriate documents, without recourse and without representation or
warranty, necessary to evidence the transfer by subrogation to such Guarantor of
an interest in the Guaranteed Obligations resulting from such payment by such
Guarantor.

THE ADMINISTRATIVE AGENT

         Appointment, Powers and Immunities. Each Lender hereby irrevocably
appoints and authorizes the Administrative Agent to act as its agent hereunder
with such powers as are specifically delegated to the Administrative Agent by
the terms of this Agreement, together with such other powers as are reasonably
incidental thereto. The Administrative Agent (which term as used in this
sentence and in Section 8.05 and the first sentence of Section 8.06 hereof shall
include reference to its affiliates and its own and its affiliates' officers,
directors, employees and agents): (a) shall have no duties or responsibilities
except those expressly set forth in this Agreement , and shall not by reason of
this Agreement be a trustee for any Lender; (b) shall not be responsible to the
Lenders for any recitals, statements, representations or warranties contained in
this Agreement, or in any certificate or other document referred to or provided
for in, or received by any of them under, this Agreement or any other document
executed hereunder, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement, any Note or any other document
referred to or provided for herein or therein or for any failure by the Borrower
or any other Person to perform any of its obligations hereunder or thereunder;
(c) shall not be required to initiate or conduct any litigation or collection
proceedings hereunder or under any other document executed hereunder; and (d)
shall not be responsible for any action taken or omitted to be taken by it
hereunder or under any other document or instrument referred to or provided for
herein or therein or in connection herewith or therewith, except for its own
gross negligence or willful misconduct. The Administrative Agent may employ
agents and attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it in good faith.
The Administrative Agent may deem and treat the payee of any Note as the holder
thereof for all purposes hereof unless and until a notice of the assignment or
transfer thereof shall have been filed with the Administrative Agent.

         Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely upon any certification, notice or other communication
(including, without limitation, any thereof by telephone, telecopy, telex,
telegram or cable) believed by it to be genuine and correct and to have been
signed or sent by or on behalf of the proper Person or Persons, and upon advice
and statements of legal counsel, independent accountants and other experts
selected by the Administrative Agent. As to any matters not expressly provided
for by this Agreement or any other documents, the Administrative Agent shall in
all cases be fully protected in acting, or in refraining from acting, hereunder
or thereunder in accordance with instructions given by the Required Lenders or,
if provided herein, in accordance with the instructions given by all of the
Lenders as is required in such circumstance, and such instructions of such
Lenders and any action taken or failure to act pursuant thereto shall be binding
on all of the Lenders.

         Defaults. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has received notice from a Lender or any Loan Party specifying such
Default and stating that such notice is a "Notice of Default". In the event that
the Administrative Agent receives such a notice of the occurrence of a Default,
the Administrative Agent shall give prompt notice thereof to the Lenders. The
Administrative Agent shall (subject to Section 8.07 hereof) take such action
with respect to such Default as shall be directed by the Required Lenders,
provided that, unless and until the Administrative Agent shall have received
such directions, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default as it shall deem advisable in the best interest of the Lenders except to
the extent that this Agreement expressly requires that such action be taken, or
not be taken, only with the consent or upon the authorization of the Required
Lenders, or all of the Lenders.

         Rights as a Lender. With respect to its Commitments and the Advances
made by it, the Administrative Agent (and any successor acting as Administrative
Agent) in its capacity as a Lender hereunder shall have the same rights and
powers hereunder as any other Lender and may exercise the same as though it were
not acting as the Administrative Agent, and the term "Lender" or "Lenders"
shall, unless the context otherwise indicates, include the Administrative Agent
in its individual capacity. Banco Popular (and any successor acting as
Administrative Agent) and its affiliates may (without having to account therefor
to any Lender) accept deposits from, lend money to, make investments in and
generally engage in any kind of banking, trust or other business with the Loan
Parties (and any of their Subsidiaries or Affiliates) as if it were not acting
as the Administrative Agent, and Banco Popular and its affiliates may accept
fees and other consideration from the Loan Parties for services in connection
with this Agreement or otherwise without having to account for the same to the
Lenders.

         Indemnification. The Lenders agree to indemnify the Administrative
Agent (to the extent not reimbursed under Section 9.04 hereof, but without
limiting the obligations of the Borrower under said Section 9.04, ratably in


<PAGE>   26


accordance with the aggregate principal amount of the Advances held by the
Lenders (or, if no Loans are at the time outstanding, ratably in accordance with
their respective Commitments), for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Administrative Agent (including by any Lender) arising out
of or by reason of any investigation in or in any way relating to or arising out
of this Agreement or any other documents contemplated by or referred to herein
or therein or the transactions contemplated hereby or thereby (including,
without limitation, the costs and expenses that the Borrower is obligated to pay
under Section 9.04 hereof, but excluding, unless a Default has occurred and is
continuing, normal administrative costs and expenses incident to the performance
of its agency duties hereunder) or the enforcement of any of the terms hereof or
thereof or of any such other documents, provided that no Lender shall be liable
for any of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the party to be indemnified.

         Non-Reliance on Administrative Agent and Other Lenders. Each Lender
agrees that it has, independently and without reliance on the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Borrower and its
Subsidiaries and decision to enter into this Agreement and that it will,
independently and without reliance upon the Administrative 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 analysis and decisions in taking or not
taking action under this Agreement or under any other documents. The
Administrative Agent shall not be required to keep itself informed as to the
performance or observance by any Loan Party of this Agreement or any of the
other documents or any other document referred to or provided for herein or
therein or to inspect the Properties or books of the Borrower or any of its
Subsidiaries. Except for notices, reports and other documents and information
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder or under the documents, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition or business of the
Borrower or any of its Subsidiaries (or any of their affiliates) that may come
into the possession of the Administrative Agent or any of its Affiliates.

         Failure to Act. Except for action expressly required of the
Administrative Agent hereunder and under the other documents, the Administrative
Agent shall in all cases be fully justified in failing or refusing to act
hereunder and thereunder unless it shall receive further assurances to its
satisfaction from the Lenders of their indemnification obligations under Section
8.05 hereof against any and all liability and expense that may be incurred by it
by reason of taking or continuing to take any such action.

         Resignation or Removal of Administrative Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Borrower, and the Administrative Agent 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 Administrative Agent with the prior consent of the Borrower (which
consent shall not be unreasonably withheld); provided that no such consent of
the Borrower shall be required if an Event of Default has occurred and is
continuing and the Commitments have been terminated and/or the Loans and other
amounts payable by the Loan Parties hereunder have been declared forthwith due
and payable. If no successor Administrative Agent shall have been so appointed
by the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent's giving of notice of resignation or the
Required Lenders' removal of the retiring Administrative Agent, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, that shall be a bank with a combined capital and surplus
of at least $500,000,000. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative Agent, the provisions of this Section 8
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent
hereunder.

MISCELLANEOUS

         Amendments, Etc. l) Any provision of this Agreement may be amended,
modified or supplemented only by an instrument in writing signed by the
Borrower, the Administrative Agent and the Required Lenders, or by the

<PAGE>   27


Borrower and the Administrative Agent acting with the consent of the Required
Lenders, and any provision of this Agreement may be waived by the Required
Lenders or by the Administrative Agent acting with the consent of the Required
Lenders; provided that: (x) no modification, supplement or waiver shall, unless
by an instrument signed by all of the Lenders or by the Administrative Agent
acting with the consent of all of the Lenders: (i) increase, or extend the term
of any of the Commitments, or extend the time or waive any requirement for the
reduction or termination of any of the Commitments; (ii) reduce or terminate,
other than reductions or termination of Commitments made by the Borrower as
permitted in Section 2.02 hereof, the Commitment(s) of any Lender; (iii) extend
the date fixed for the payment of principal of or interest on any Revolving
Credit Advance, or any fee hereunder; (iv) reduce the amount of any such payment
of principal; (v) reduce the rate at which interest is payable thereon or any
fee is payable hereunder; (vi) alter the rights or obligations of the Borrower
to prepay Loans; (vii) alter the terms of this Section 9.01; (viii) modify the
definition of the term "Required Lenders", or modify in any other manner the
number or percentage of the Lenders required to make any determinations or waive
any rights hereunder or to modify any provision hereof; (ix) release any
Guarantor from any of its guarantee obligations under Article VII hereof; or (x)
waive any of the conditions precedent set forth in Article III hereof; and (y)
any modification of any of the rights or obligations of the Administrative Agent
shall require the consent of the Administrative Agent.

Each Lender grants (x) to the Administrative Agent the right to purchase all
(but not less than all) of such Lender's Commitments and Advances owing to it
and the Notes held by it and all of its rights and obligations hereunder and
under the other documents at a price equal to the aggregate amount of
outstanding Advances owed to such Lender (together with all accrued and unpaid
interest and fees owed to such Lender); and (y) to the Borrower the right to
cause an assignment of all (but not less than all) of such Lender's Commitments
and Advances owing to it and the Notes held by it and all of its rights and
obligations hereunder and under the other documents to Eligible Assignees, which
right may be exercised by the Administrative Agent or the Borrower, as the case
may be, if such Lender refuses to execute any amendment, waiver or consent which
requires the written consent of all the Lenders and to which Lenders owed at
least 90% of the aggregate unpaid principal amount of Revolving Credit Advances
or, if no such principal amount is then outstanding, Lenders having at least 90%
of the Commitments, the Administrative Agent and the Borrower have agreed. Each
Lender agrees that if the Administrative Agent or the Borrower, as the case may
be, exercises its option hereunder, it shall promptly execute and deliver all
agreements and documentation necessary to effectuate such assignment as set
forth in Section 9.07.

reasonable out-of-pocket costs and expenses of the Administrative Agent in
connection with the preparation, execution, delivery, administration,
modification and amendment of this Agreement, the Notes and the other documents
to be delivered hereunder, including, without limitation, the reasonable fees

Such expenses shall be paid by the Borrower upon presentation of an itemized
statement of account (after the Borrower has had reasonable time to review such
statement of account) following consummation of the transactions contemplated by
this Agreement. The Borrower further agrees to pay on demand all costs and
expenses of the Administrative Agent and the Lenders, if any (including, without
limitation, reasonable counsel fees and expenses), 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
Administrative Agent and each Lender in connection with the enforcement of
rights under this Section 9.04(a).

The Borrower agrees to indemnify and hold harmless the Administrative 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,
any of the transactions contemplated herein 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 their respective
Subsidiaries or any Environmental Action relating in any way to the Borrower or
any of their respective Subsidiaries, in each case whether or not such
investigation, litigation or proceeding is brought by any Loan Party, 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 (A) is found by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence or
willful misconduct; (B) arises from disputes among two or more Lenders (but not
including any such dispute that involves a Lender to the extent such Lender is
acting in any different capacity (i.e., Administrative Agent or Arranger) under
the Credit Agreement or the Notes or to the extent that it involves the
Administrative Agent's syndication activities); or (C) arises from or relates to
a breach by such Indemnified Party of its obligations under this Agreement. The
Borrower also agrees not to assert any claim against the Administrative 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, any of the transactions contemplated
herein or the actual or proposed use of the proceeds of the Advances.

If any payment of principal of, or Conversion of, any LIBOR Rate Advance is made
by the Borrower (or pursuant to Section 9.01(b)) 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, prepayment or Conversion pursuant to this Agreement or
acceleration of the maturity of the Notes pursuant to Section 6.01, the Borrower
shall, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative 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 (excluding 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.


<PAGE>   30

Without prejudice to the survival of any other agreement of the Borrower
hereunder, the agreements and obligations of the Borrower contained in Sections
2.12 and 9.04 shall survive the payment in full of principal, interest and all
other amounts payable hereunder and under the Notes.

         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 by the Required Lenders to authorize the
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01 and notice to the Borrower as required under 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 any Loan Party against
any and all of the obligations of such Loan Party now or hereafter existing
under this 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 the
applicable Loan Party after any such set-off and application, provided that the
failure to give 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.

         Binding Effect. This Agreement shall become effective (other than
Section 2.01, 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 Administrative Agent and when the Administrative Agent
shall have been notified by each Lender that such Lender has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, the
Guarantors, the Administrative Agent and each Lender and their respective
successors and assigns, except that neither the Borrower nor the Guarantors
shall have the right to assign its rights hereunder or any interest herein
without the prior written consent of the Lenders.

         Assignments and Participations. n) Each Lender may, with the consent of
the Administrative Agent (except as provided in clause (g) below) and the
Borrower (such consent not to be unreasonably withheld) and, if demanded by the
Borrower pursuant to Section 9.01(b) or following a request for a payment to or
on behalf of such Lender under Section 2.10 or Section 2.13 or following a
notice given by such Lender pursuant to Section 2.11, upon at least ten Business
Days' notice to such Lender and the Administrative Agent, will, 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, that the Borrower may make demand with respect to a
Lender that has given notice pursuant to Section 2.11 only if the Borrower makes
such demand of all Lenders similarly situated that have given such notice;
provided, further, that: (i) each such assignment shall be of a constant, and
not a varying, percentage of all rights and obligations under this Agreement and
the Revolving Credit 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 $5,000,000 or an
integral multiple of $1,000,000 in excess thereof; (iii) each such assignment
shall be to an Eligible Assignee; (iv) each such assignment made as a result of
a demand by the Borrower shall be arranged by the Borrower after consultation
with the Administrative Agent and shall be either an assignment of all of the
rights and obligations of the assigning Lender under this Agreement or an
assignment of a portion of such rights and obligations made concurrently with
another such assignment or other such assignments that together cover all of the
rights and obligations of the assigning Lender under this Agreement; (v) no
Lender shall be obligated to make any such assignment as a result of a demand by
the Borrower unless and until such Lender shall have received one or more
payments from either the Borrower or one or more Eligible Assignees in an
aggregate amount at least equal to the aggregate outstanding principal amount of
the Advances owing to such Lender, together with accrued interest thereon to the
date of payment of such principal and all other amounts payable to such Lender
under this Agreement; (vi) no Lender shall at any time have more than two (2)
assignees that were not Initial Lenders; and (vii) the parties to each such
assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance, together
with any Revolving Credit Notes subject to such assignment and a processing and
recordation fee of $2,500 (which shall be paid by Persons other than the
Borrower unless such assignment is made as a result of a demand by the
Borrower). Upon such execution, delivery, acceptance and recording, from and
after the effective date specified in each Assignment


<PAGE>   31

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 other than rights of
indemnification under Section 9.04 or otherwise relating to a time prior to the
effective date of such Assignment and Acceptance 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).

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 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 any Loan
Party or the performance or observance by any Loan Party 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 Administrative 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 Administrative 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 Administrative 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.

Upon its receipt of an Assignment and Acceptance executed by an assigning
Lender, an assignee representing that it is an Eligible Assignee and the
Borrower, together with the Revolving Credit Note or Notes subject to such
assignment, the Administrative 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 Administrative 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.

The Administrative Agent shall maintain at its address referred to in Section
9.02 a copy of each Assignment and Acceptance delivered to and accepted by it
and a register for the recordation of the names and addresses of the Lenders and
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
Borrower, the Administrative 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.

(e) 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 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





<PAGE>   32


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 Administrative 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 that a Lender may agree with a participant as to the
manner in which the Lender shall exercise the Lender's rights to approve any
amendment, waiver or consent 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.

(f) Any Lender may at any time, without the consent of the Administrative Agent
or the Borrower, 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, provided, however, that no such assignment shall have the effect of
increasing the costs payable by the Borrower.

         Nondisclosure. None of the Administrative Agent, any Lender or any
Affiliate thereof shall disclose without the prior consent of the Borrower
(other than to the Administrative Agent, or another Lender or any such
Affiliate, their respective directors, employees, auditors, affiliates or
counsel who shall agree to be bound by the terms of this provision) any
information with respect to the Loan Parties or any Subsidiary thereof contained
in financial statements, projections or reports provided to the Administrative
Agent, any Lender or any Affiliate thereof by, or on behalf of, the Loan Parties
or any Subsidiary, provided that the Administrative Agent, any Lender or any
Affiliate thereof may disclose any such information: (a) as has become generally
available to the public in a manner, or through actions, which do not violate
the terms of this Section 9.08; (b) to, or as may be required or appropriate in
any report, statement or testimony submitted to, any municipal, state,
Commonwealth of Puerto Rico, or federal regulatory body having or claiming to
have jurisdiction over the Administrative Agent, any Lender or any Affiliate
thereof or to the Federal Reserve Board or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States or elsewhere)
or their successors; (c) as may be required or appropriate in response to any
summons or subpoena or in connection with any litigation; (d) in order to comply
with any law, order, regulation or ruling applicable to the Administrative
Agent, any Lender or any Affiliate thereof; and (e) to a prospective co-lender
or participant in the amounts outstanding hereunder or under the Advances,
provided, however, that such prospective co-lender or participant executes an
agreement containing provisions substantially identical to those contained in
this Section 9.08 and which shall by its terms inure to the benefit of the
Borrower and provided, further, that to the extent practicable, the
Administrative Agent, each Lender and their respective Affiliates shall use
reasonable best efforts to provide prior written notice of such disclosure to
the Borrower.

         Governing Law. This Agreement and the Notes shall be governed by, and
construed in accordance with, the laws of the Commonwealth of Puerto Rico.

         Jurisdiction, Etc. o) Each of the Loan Parties hereby agrees that any
suit, action or proceeding with respect to this Agreement or the Notes or any
other document executed hereunder to which it is a party or any judgment entered
by any court in respect thereof may be brought in the United States District
Court for the District of Puerto Rico or in the Court of First Instance of
Puerto Rico sitting in San Juan, as the party commencing such suit, action or
proceeding may elect in its sole discretion; and each party hereto hereby
irrevocably submits to the non-exclusive jurisdiction of such court for the
purpose of any such suit, action, proceeding or judgment. Each party hereto
further submits, for the purpose of any such suit, action, proceeding or
judgment brought or rendered against it, to the appropriate courts of the
jurisdiction of its domicile.

Each of the Loan Parties hereby irrevocably consents to the service of process
in any suit, action or proceeding in such courts by the mailing thereof by the
Administrative Agent or any Lender by registered or certified mail, postage
prepaid, at its address set forth beneath its signature hereto. Nothing herein
shall in any way be deemed to limit the ability of the Administrative Agent or
any Lender to serve any such writs, process or summonses in any other manner
permitted by applicable law or to obtain jurisdiction over the Loan Parties in
such other jurisdictions, and in such manner, as may be permitted by applicable
law.


<PAGE>   33

Each of the Loan Parties hereby irrevocably waives any objection that it may now
or hereafter have to the laying of the venue of any suit, action or proceeding
arising out of or relating to this Agreement, the Notes or any document executed
hereunder brought in any such court and hereby further irrevocably waives any
claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum.

         Waiver of Jury Trial. Each of the Borrower, the Guarantor, the
Administrative Agent and the Lenders hereby irrevocably waives all right to
trial by jury in any action, proceeding or counterclaim (whether based on
contract, tort or otherwise) arising out of or relating to this Agreement or the
Notes or the actions of the Administrative Agent or any Lender in the
negotiation, administration, performance or enforcement thereof.

         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.

         Exhibits and Schedules Incorporated. The Exhibits and Schedules annexed
hereto are hereby incorporated by reference herein as part of this Agreement
with the same effect as if set forth in the body hereof.
