aggregate amount of $1,000,000 or an integral multiple of $1,000,000 in excess
thereof. 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.

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. (Puerto Rico 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 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 (Puerto Rico
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.

(b) 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.

(c) 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.

(d) 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).

(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 the 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 the


<PAGE>   10

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 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 in arrears quarterly on the last day of
each March, June, September and December, commencing on June 30, 2000, and on
the Termination Date.

SECTION 2.04 Termination or Reduction of the Commitments. 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.

SECTION 2.05 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.

SECTION 2.06 Interest.

(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 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 Base Rate 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 Base Rate Advance shall
be Converted or paid in full.

(ii) 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.

(b) 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 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 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.

SECTION 2.07 Interest Rate Determination. (a) 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, any Lender notifies the
Administrative Agent that the LIBOR Rate for any Interest Period for such
Advances will not adequately reflect the cost to such Lender 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



<PAGE>   11

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

(b) 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.

(c) 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.

(d) 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.

(e) 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,

(i) the Administrative Agent shall forthwith notify the Borrower and the Lenders
that the interest rate cannot be determined for such LIBOR Rate Advances,

(ii) 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

(iii) the obligation of the Lenders 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.

SECTION 2.08 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. (Puerto Rico 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.

SECTION 2.09 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 (y) the Borrower shall be obligated to
reimburse the Lenders in respect thereof pursuant to Section 9.04(b).

SECTION 2.10 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 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



<PAGE>   12


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 the date of 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 manifest error in the
calculation of such amount.

(b) 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 (taking into consideration such Lender's policies
and the policies of any corporation controlling such Lender with respect to
capital adequacy) 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
manifest error in the calculation of such amounts.

(c) 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 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.

SECTION 2.11 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.

SECTION 2.12 Payments and Computations. (a) The Borrower shall make each payment
hereunder and under the Notes not later than 11:00 A.M. (Puerto Rico 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






<PAGE>   13


to be distributed like funds relating to the payment of principal or interest or
facility fees ratably (other than amounts payable pursuant to Section 2.10 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.

(b) All computations of interest 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 manifest error in the
calculation of such interest rate.

(c) 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.

(d) 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.

SECTION 2.13 Taxes. (a) 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 imposed by the
Commonwealth of Puerto Rico, the United States or any political subdivision of
either (or in the case of any payments by or on behalf of the Borrower through
an account or branch outside the United States or the Commonwealth of Puerto
Rico or by or on behalf of the Borrower by a payor that is not a United States
person or not organized or resident in the Commonwealth of Puerto Rico such
payments shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto imposed by a foreign jurisdiction or
any political subdivision thereof), 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 (x) in the case of a Lender
pursuant to the laws of the jurisdiction (or any political subdivision or taxing
authority therein) in which it is organized or in which the principal office of
such Lender or Applicable Lending Office of such Lender is located, or (y) in
the case of any payment to the Administrative Agent in its capacity as
Administrative Agent, the jurisdiction (or any political subdivision or taxing
authority therein) in which it is organized or in which the principal office of
the Administrative Agent is located or in which the office designated by the
Administrative Agent to act as Administrative Agent is located (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
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. For purposes of this subsection (a) and subsection (e),

<PAGE>   14

the terms "United States" and "United States person" shall have the meanings
specified in Section 7701 of the Internal Revenue Code.

(b) 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 (hereinafter referred to as "Other Taxes").

(c) 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) on or with respect to any payment by or on account of any obligation of any
Loan Party hereunder or under any other Loan Document and any liability
(including penalties, interest and expenses but excluding any taxes imposed by
any jurisdiction on amounts which may be paid or payable by the Borrower to a
Lender or the Administrative Agent under this Section 2.13) arising therefrom or
with respect thereto whether or not such Taxes or Other Taxes were correctly or
legally imposed. This indemnification shall be made within 30 Business Days from
the date such Lender or the Administrative Agent (as the case may be) makes
written demand therefor. A certificate as to the amount of such payment or
liability, submitted to the Borrower and the Administrative Agent by such
Lender, shall be conclusive and binding for all purposes, absent manifest error
in the calculation of such amount or liability.

(d) Each Lender organized under the laws of a jurisdiction outside of the
Commonwealth of Puerto Rico from time to time 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 Administrative Agent and the Borrower with two properly and
accurately completed and duly executed original copies of any form, document or
other certificate that is necessary for such Lender to be exempt from, or
entitled to a reduced rate of Taxes or payments hereunder or under the Notes or
for the Borrower to determine the applicable rate of deduction or withholding of
any Taxes. If any Lender which is organized under the laws of a jurisdiction
outside of the Commonwealth of Puerto Rico is unable to provide the
above-described forms, documents or other certificates for a relevant interest
period (or if the Lender's appropriate personnel responsible for providing the
forms, documents or other certificates actually become aware that the forms,
documents or other certificates provided by it are inaccurate), such Lender
shall notify the Borrower in writing prior to or immediately upon the
commencement of such relevant interest period.

(e) For any period with respect to which a Lender has failed to provide the
Borrower with the appropriate form, document or other certificate requested by
the Borrower in accordance with Section 2.13(d) (other than if such failure is
due to a change in law occurring subsequent to the date on which a form,
document or other certificate originally was required to be provided, or if such
form, document or other certificate is no longer required to establish an
exemption from the applicable tax), such Lender shall not be entitled to
indemnification under Section 2.13(a) or (c) with respect to Taxes by reason of
such failure and the Borrower shall be entitled to withhold Taxes from payments
to such Lender; provided, however, that should a Lender become subject to Taxes
because of its failure to deliver a form, document or other certificate required
hereunder, the Borrower shall take such steps at such Lender's expense as such
Lender shall reasonably request to assist such Lender to recover such Taxes.

(f) Notwithstanding anything else contained in this Section 2.13, the Borrower
shall only be required to pay additional sums with respect to Taxes (subject to
subsection (h) below) to a Lender (or the Administrative Agent, as the case may
be) pursuant to subsection (a) or (c) above if the obligation to pay such Taxes
results from such Lender's inability to obtain a complete exemption from 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).



<PAGE>   15



(g) 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.

(h) 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 the jurisdiction of its LIBOR 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.

SECTION 2.14 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).

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 Advances made by it (other than pursuant to
Section 2.10, 2.13, 9.04(c) or 9.07) in excess of its ratable share of payments
on account of the Advances obtained by all the Lenders, such Lender shall
forthwith purchase from the other Lenders such participations in the Advances
made by 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

this Agreement or the Notes.

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

action or proceeding, including, without limitation, any Environmental Action,

assessed by any such authority, and all contested assessments have been
disclosed to the Administrative Agent and adequate reserves have been made
therefor. Such tax returns properly reflect the income and taxes of each
respective Loan Party and its Subsidiaries for the periods covered thereby,
subject only to reasonable adjustments required by the corresponding taxing
authorities upon audit or other adjustments not reasonably likely to have a
Material Adverse Effect.

(l) No Loan Party is subject to any labor dispute with its employees which is

or defeasance or offer therefore is the occurrence of an event or condition that
is premised on a material adverse deterioration of the financial condition,
results of operation or properties of the Borrower or any of its Subsidiaries,
provided that with respect to Debt aggregating the Requisite Amount of the types
described in clauses (h) or (i) of the definition of "Debt" and to the extent
such Debt relates to the obligations of any Person other than the Borrower or
any of its Subsidiaries, no Event of Default shall occur so long as the payment
of such Debt is being contested in good faith and by proper proceedings and as
to which appropriate reserves are being maintained; or any event shall occur or
condition shall exist under any agreement or instrument relating to any Debt
that is outstanding in a principal or in the case of Hedge Agreements net amount
of at least $40,000,000 and shall continue after the applicable grace period, if
any, specified in such agreement or instrument, if the effect of such event or
condition is to accelerate, or permit the acceleration of, the maturity of such
Debt; or

(f) Any Loan Party or any of its Subsidiaries shall generally not pay their
respective debts as such debts become due, or shall admit in writing its
inability to pay its debts generally, or shall make a general assignment for the
benefit of creditors; or any proceeding shall be instituted by or against any
Loan Party or its Subsidiaries seeking to adjudicate it a bankrupt or insolvent,
or seeking liquidation, winding up, reorganization, arrangement, adjustment,
protection, relief, or composition of it or its debts under any law relating to
bankruptcy, insolvency or reorganization or relief of debtors, or seeking the

property and, in the case of any such proceeding instituted

official for, it or for any substantial part of its property) shall occur; or
any Loan Party or its Subsidiaries shall take any corporate action to authorize
any of the actions set forth in this subsection (f) under any law relating to
bankruptcy, insolvency or reorganization or relief of debtors; or

(g) Any judgment or order for the payment of money in excess of $30,000,000
shall be rendered against any Loan Party or its Subsidiaries and enforcement
proceedings shall have been commenced by any creditor upon such judgment or
order for which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect; provided, however, that any
such judgment or order shall not be an Event of Default under this Section
6.01(g) if and for so long as (i) (A) the amount of such judgment or order is
covered by a valid and binding policy of insurance between the defendant and the

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 any
Loan Party 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

         ARTICLE VII GUARANTY

SECTION 7.01 Guaranty; Limitation of Liability. (a) In order to induce the
Lenders to extend credit to the Borrower hereunder, each Guarantor hereby
jointly and severally and unconditionally and irrevocably guarantees, as a
primary obligor and not merely as a surety, 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.

(b) 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 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.

(c) 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.

SECTION 7.02 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:

(a) any lack of validity or enforce ability of this Agreement or any agreement
or instrument relating hereto;

(b) 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, any Note or any





<PAGE>   27


other Loan Document, including, without limitation, any increase in the
Guaranteed Obligations resulting from the extension of additional credit to the
Borrower or otherwise;

(c) 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;

(d) any change, restructuring or termination of the corporate structure or
existence of the Borrower; or

(e) 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.

SECTION 7.03 Waiver. Each Guarantor hereby waives 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.

SECTION 7.04 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.

SECTION 7.05 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


<PAGE>   28


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.

ARTICLE VIII THE ADMINISTRATIVE AGENT

SECTION 8.01 Authorization and Action. Each Lender hereby appoints and
authorizes the Administrative Agent to take such action as Administrative 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. As to any
matters not expressly provided for by this Agreement (including, without
limitation, enforcement or collection of the Notes), the Administrative 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 Majority Lenders
and such instructions shall be binding upon all Lenders and all holders of
Notes; provided, however, that the Administrative Agent shall not be required to
take any action that exposes the Administrative Agent to personal liability or
that is contrary to this Agreement or applicable law. The Administrative 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 8.02 Administrative Agent's Reliance, Etc. Neither the Administrative
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 Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the
Administrative Agent: (i) 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; (ii) 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; (iii)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of 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 except as specifically set forth in this Agreement;
(iv) shall not be responsible to any Lender for the due execution, legality,
validity, enforce ability, genuineness, sufficiency or value of this Agreement
or any other instrument or document furnished pursuant hereto; and (v) 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 8.03 BBVPR and Affiliates. With respect to its Commitment, the Advances
made by it and the Note or Notes issued to it, BBVPR 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 Administrative Agent; and the term "Lender" or "Lenders"
shall, unless otherwise expressly indicated, include BBVPR in its individual
capacity. BBVPR 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, any Loan Party, any of its
Subsidiaries and any Person who may do business with or own securities of any
Loan Party or any of its Subsidiaries, all as if BBVPR were not the
Administrative Agent and without any duty to account therefore to the Lenders.

SECTION 8.04 Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative 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
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
credit decisions in taking or not taking action under this Agreement.

SECTION 8.05 Indemnification. The Lenders agree to indemnify the Administrative
Agent (to the extent not reimbursed by the Borrower), ratably according to the
respective principal amounts of the Revolving Credit Advances owed each of them
(or if no Revolving Credit Advances are at the time outstanding, ratably
according to



<PAGE>   29


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 Administrative Agent in any way relating to or
arising out of this Agreement or any action taken or omitted by the
Administrative Agent under this Agreement, 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 Administrative Agent's gross negligence or willful misconduct. Without
limitation of the foregoing, each Lender agrees to reimburse the Administrative
Agent promptly upon demand for its ratable share of any out-of-pocket expenses
(including reasonable counsel fees) incurred by the Administrative 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, this Agreement, to the extent that the Administrative
Agent is not reimbursed for such expenses by the Borrower.

SECTION 8.06 Successor Administrative Agent. The Administrative 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 Majority Lenders. Upon
any such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Agent. If no successor Administrative Agent
shall have been so appointed by the Majority Lenders, and shall have accepted
such appointment, within 30 days after the retiring Administrative Agent's
giving of notice of resignation or the Majority Lenders' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent, which shall be a
commercial bank organized or licensed under the laws of the United States of
America or of any State thereof or the Commonwealth of Puerto Rico and having a
combined capital and surplus of at least $250,000,000. 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, discretion, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent, upon
appointment of such successor Administrative Agent, shall be discharged from its
duties and obligations under this Agreement. After any retiring Administrative
Agent's resignation or removal hereunder as Administrative Agent, the provisions
of this Article VIII shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement.

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

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.

(b) 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.

(c) 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.

SECTION 9.05 Right of Set-off. Upon the occurrence and during the continuance of
any Event of Default, 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






<PAGE>   33

in addition to other rights and remedies (including, without limitation, other
rights of set-off) that such Lender and its Affiliates may have.

SECTION 9.06 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 each Loan Party, the Administrative Agent and by each initial Lender and
thereafter shall be binding upon and inure to the benefit of each Loan Party,
the Administrative Agent and each Lender and their respective successors and
assigns, except that no Loan Party shall not have the right to assign its rights
hereunder or any interest herein without the prior written consent of the
Majority Lenders.

SECTION 9.07 Assignments and Participations. Each Lender may assign to one or
more banks or other entities all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitments, the Advances, the Note or Notes held by it and the remaining Loan
Documents); provided, however, that (i) 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 (as hereinafter defined) with
respect to such assignment) shall in no event be less than $1,000,000 (unless
such lesser amount is the entire amount of such assigning Lender's Commitment or
outstanding Advances) and shall be an integral multiple of $100,000, (ii) each
such assignment shall be to an Eligible Assignee or to an Affiliate of the
assignor, and (iii) the parties to each such assignment shall execute and
deliver to the Administrative Agent, an Assignment and Acceptance, together with
any Note or Notes subject to such assignment and a processing fee of $2,500.00.
Upon such execution, delivery and acceptance, from and after the effective date
specified in each Assignment and Acceptance, 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 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).

(a) 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 their
respective 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(e) 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
under this Agreement and the other Loan Documents as are delegated to the
Administrative Agent by the terms hereof and thereof, together with such powers
as are reasonably incidental thereto; and (vii) such assignee 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.

(b) Upon its receipt of an Assignment and Acceptance in substantially the form
of Exhibit E hereto (the "Assignment and Acceptance") executed by an assigning
Lender and an assignee representing that it is an Eligible Assignee, together
with any Note or Notes subject to such assignment, the Administrative Agent
shall, if such Assignment and Acceptance has been duly completed, (i) accept
such Assignment and Acceptance and (ii) give prompt notice thereof to the
Borrower. Within five (5) Business Days after its receipt of such notice, the
Borrower, at their own expense, shall execute and deliver to the Administrative
Agent, in exchange for the surrendered Note or





<PAGE>   34


Notes, a new Note or new Notes to the order of such Eligible Assignee in an
amount equal to the Commitments assumed by it pursuant to such Assignment and
Acceptance and, if the assigning Lender has retained a Commitment hereunder, a
new Note or new Notes to the order of the assigning Lender in an amount equal to
the Commitment(s) retained by it hereunder. Such new Note or Notes shall be in
an aggregate principal amount equal to the aggregate principal amount of such
surrendered Note or Notes, shall be dated the effective date of such Assignment
and shall otherwise be in substantially the form of Exhibit A.

(c) 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 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 and (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, (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.

(d) 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.

SECTION 9.08 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, the other 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 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 assignee and/or participant in the amounts outstanding hereunder or
under the Advances, provided, however, that such prospective assignee and/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.

SECTION 9.09 Governing Law. This Agreement and the Notes shall be governed by,
and construed in accordance with, the laws of the Commonwealth of Puerto Rico.

suit, action or proceeding with respect to this Agreement or the Notes, the
other Loan Documents or any other document executed hereunder to



<PAGE>   35

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.

(a) 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.

(b) 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.

SECTION 9.11 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, the
Notes or the other Loan Documents or the actions of the Administrative Agent or
any Lender in the negotiation, administration, performance or enforcement
thereof.

SECTION 9.12 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.

IN WITNESS WHEREOF, the parties hereto have caused this Revolving Credit
