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

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. Within the limits of this Section 2.01, the
Borrower may borrow under this Section 2.01, prepay pursuant to Section 2.09,

         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 Business Day of the
proposed Revolving Credit Borrowing by the Borrower to the Administrative Agent,
which shall give to each Lender prompt notice thereof by telecopier or telex.

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

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

                                                                               8

<PAGE>   9


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 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 September 30, 2001, 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.


                                                                               9

<PAGE>   10

         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 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.

                                                                              10

<PAGE>   11


                  (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 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

                                                                              11

<PAGE>   12


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 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

                                                                              12

<PAGE>   13


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), 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.

                                                                              13

<PAGE>   14


                  (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).

                  (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

                                                                              14

<PAGE>   15


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 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 the amount of such Lender's required repayment
to the total amount so recovered from the purchasing Lender) of any interest or
other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 2.15 may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Lender were the direct creditor of the Borrower in the amount of such
participation.

                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

         SECTION 4.01 Representations and Warranties of the Borrower. In order
to induce the Lenders to make the Revolving Credit Advances hereunder, the
Borrower makes the following representations and warranties to the Lenders:

                  (a) Each Loan Party is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation.

                  (b) The execution, delivery and performance by each Loan Party
of this Agreement and the Notes executed by it and the consummation of the
transactions contemplated hereby, are within such Loan Party's corporate powers,
have been duly authorized by all necessary corporate action, and do not
contravene (i) such Loan Party's charter or by-laws (or other equivalent
organizational documents) or (ii) any law or any material contractual
restriction binding on or affecting such Loan Party or, to the knowledge of such
Loan Party's chief executive officer, chief financial officer, treasurer or
controller or any vice president, any other contract the breach of which would
limit the ability of any Loan Party to perform its obligations under this
Agreement or the Notes. No Loan Party nor any Subsidiary of a Loan Party is in
violation of any law, rule, regulation, order, writ, judgment, injunction,
decree, determination or award applicable to it, or in breach of any indenture,
agreement, lease or instrument, the violation or breach of which is reasonably
likely to have a Material Adverse Effect.

                  (c) No authorization or approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body or any
other third party is required for the due execution, delivery and performance by
any Loan Party of this Agreement or the Notes.

                  (d) 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 been duly executed by the Administrative Agent and each
of the Lenders, this Agreement is, and each of the Notes when delivered
hereunder will be, the legal, valid and binding obligation of the Borrower
enforceable against the Borrower in accordance with their respective terms.
Assuming that this Agreement has been duly executed by the Administrative Agent
and each of the Lenders, this Agreement is

                                                                              17

<PAGE>   18


the legal, valid and binding obligation of each Guarantor enforceable against
each Guarantor in accordance with its terms.

                  (e) The Consolidated balance sheet of the Borrower (or its
predecessor entities) and its Subsidiaries as at December 31, 2000, and the
related Consolidated statements of income and cash flows of the Borrower (or its
predecessor entities) and its Subsidiaries for the fiscal year then ended,
accompanied by an opinion of Deloitte & Touche LP, independent public
accountants, copies of which have been furnished to each Lender, fairly and
accurately represent the Consolidated financial condition of the Borrower and
its Subsidiaries as at such date and the Consolidated results of the operations
of the Borrower and its Subsidiaries for the period ended on such date, all in
accordance with generally accepted accounting principles consistently applied.

                  (f) There is no pending or (to the knowledge of any Loan
Party) threatened action or proceeding, including, without limitation, any
Environmental Action, affecting any Loan Party or any of its Subsidiaries before
any court, governmental agency or arbitrator that is initiated by any Person
other than a Lender in its capacity as a Lender that purports to affect the
legality, validity or enforceability of this Agreement or any Note.

                  (g) 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.

                  (h) No Loan Party is engaged in the business of extending
credit 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), and no proceeds of any Advance will be used to purchase or carry any
margin stock or to extend credit to others for the purpose of purchasing or
carrying any margin stock.

                  (i) As of the date hereof, the Borrower has no direct or
indirect Significant Subsidiaries, except as set forth in Schedule 4.01(i).

                  (j) The Borrower and the Guarantors are Solvent.

                  (k) Each Loan Party and each of its respective Subsidiaries
have filed all federal, state, commonwealth and local tax returns required to be
filed and have paid all taxes shown thereon to be due, including interest and
penalties, or have provided adequate reserves therefor; no unpaid or uncontested
assessments have been made against any Loan Party or any Subsidiary of any Loan
Party by any taxing authority, nor has any unpaid or uncontested penalty or
deficiency been 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 reasonably likely to have a Material Adverse Effect.

                  (m) No written information, exhibit or report furnished by any
Loan Party to the Administrative Agent or any Lender in connection with the
negotiation of this Agreement contained any material misstatement of fact or
omitted to state a material fact necessary to make the statements contained
therein not misleading.

                  (n) The operations and properties of each Loan Party comply in
all material respects with all applicable Environmental Laws; all necessary
Environmental Permits have been obtained and are in effect for the operations
and properties of each Loan Party, and each Loan Party is in compliance in all
material respects with all such Environmental Permits; none of the operations or
properties of any Loan Party is subject to any Environmental Action alleging the
violation of any Environmental Law; none of the operations of any Loan Party are
the subject of a federal, state, commonwealth or local investigation evaluating
whether any remedial action is needed to respond to a release of any hazardous
or toxic waste, substance or constituent, or any other substance into the
environment, which Environmental Action or remedial action is reasonably likely
to have a Material Adverse Effect.

                          COVENANTS OF THE LOAN PARTIES

         SECTION 5.01 Affirmative Covenants. So long as any Advance shall remain
unpaid or any Lender shall have any Commitment hereunder, each Loan Party will:

                  (a) Compliance with Laws, Etc. Comply, and cause each of its
Subsidiaries to comply, in all material respects, with all applicable laws,
rules, regulations and orders, such compliance to include, without limitation,
compliance with ERISA and Environmental Laws, except where the failure to so
comply would not have a Material Adverse Effect.

                  (b) Payment of Taxes, Etc. Pay and discharge, and cause each
of its Subsidiaries to pay and discharge, before the same shall become
delinquent, (i) all taxes, assessments and governmental charges or levies
imposed upon it or upon its property and (ii) all lawful claims that, if unpaid,
might by law become a Lien upon its property; provided, however, that neither
any Loan Party nor any of its Subsidiaries shall be required to pay or discharge
any such tax, assessment, charge or claim that is being contested in good faith
and by proper proceedings and as to which appropriate reserves are being
maintained, unless and until any Lien resulting therefrom attaches to its
property and becomes enforceable against its other creditors and the aggregate
of such Liens would have a Material Adverse Effect.

                  (c) Maintenance of Insurance. Maintain, and cause each of its
Subsidiaries to maintain, insurance with responsible and reputable insurance
companies or associations in such amounts and covering such risks as is usually
carried by companies engaged in similar businesses and owning similar properties
as such Loan Party and such Subsidiaries in the same general areas in which such
Loan Party or such Subsidiary operates; provided, however, that such Loan Party
and its Subsidiaries may self insure to the extent consistent with prudent
business practice.

                  (d) Preservation of Corporate Existence, Etc. Preserve and
maintain, and cause each of its Subsidiaries to preserve and maintain, its
corporate existence, rights (charter and statutory) and franchises; provided,
however, that each Loan Party and its Subsidiaries may consummate any
transaction permitted under Section 5.02(b) and provided further that neither
any Loan Party nor any of its Subsidiaries shall be required to preserve any
right or franchise if the senior management of such Loan Party or of such
Subsidiary shall determine that the preservation thereof is no longer desirable
in the conduct of the business of such Loan Party or such Subsidiary, as the
case may be, and that the loss thereof is not disadvantageous in any material
respect to such Loan Party or such Subsidiary or to the interests of the
Lenders.

                  (e) Visitation Rights. During normal business hours and upon
reasonable notice from time to time, permit the Administrative Agent or any of
the Lenders or any agents or representatives thereof, to examine and make copies
of and abstracts from the records and books of account of (excluding any
confidential information), and visit the properties of, such Loan Party and any
of its Subsidiaries, and to discuss the affairs, finances and accounts of such
Loan Party and any of its Subsidiaries with the appropriate representatives of
such Loan Party and together with the appropriate representatives of such Loan
Party's independent certified public accountants.

                  (f) Keeping of Books. Keep, and cause each of its Subsidiaries
to keep, proper books of record and account, in which full and correct entries
shall be made of all financial transactions and the assets and business of such
Loan Party and each such Subsidiary in accordance with GAAP, consistently
applied and generally accepted accounting principles in effect from time to
time.

                  (g) Maintenance of Properties, Etc. Maintain and preserve, and
cause each of its Subsidiaries to maintain and preserve, its material properties
that are used or useful in the conduct of its business in good working order and
condition, ordinary wear and tear excepted and in material compliance with all

                                                                              19

<PAGE>   20

on terms that are fair and reasonable and no less favorable to such Loan Party
or such Subsidiary than it would obtain in a comparable arm's-length transaction
with a Person not an Affiliate except where the failure to do so, in the
aggregate, would not have a Material Adverse Effect, (ii) as required by the
Federal Communications Commission's rules and regulations for transactions among
affiliates or (iii) as contemplated by the Management Agreement and the
Technology Transfer Agreement (each such agreement as defined in the Stock
Purchase Agreement).

                  secure Debt incurred solely for the purpose of financing the
                  acquisition of such property or equipment, or Liens existing

                  such Lien shall extend to or cover any properties of any
                  character other than the real property or equipment being
                  acquired, and no such extension, renewal or replacement shall
                  extend to or cover any properties not theretofore subject to
                  the Lien being extended, renewed or replaced,

                           (iii) the Liens existing on the Effective Date and

                  time such Person is merged into or consolidated with the
                  Borrower or any of its Subsidiaries; provided that any such
                  Liens that were created during the period immediately prior to
                  such merger, consolidation or acquisition were created in the

                  extension or renewal (without increase in the amount or
                  extension of the final maturity date) of the Debt secured
                  thereby,

                           (vi) Liens not otherwise permitted pursuant to
                  clauses (i) through (v) above securing obligations not to

         (c) Accounting Changes. Make or permit, or permit any of its
Subsidiaries to make or permit, any change in accounting policies or reporting
practices, except (i) as required or permitted by generally accepted accounting
principles or (ii) where the effect of such change, together with all other

clause (ii) since the Effective Date, is immaterial to the Borrower and its
Subsidiaries taken as a whole.

         (d) Subsidiary Debt. Permit any of its Subsidiaries to create or suffer

accordance with its terms, or any offer to prepay, redeem, purchase or defease
such Debt shall be required to be made in accordance with its terms, in each
case prior to the stated maturity thereof where the cause of such prepayment,

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

                                                                              23

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

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

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

debtors, or seeking the entry of an order for relief or the appointment of a
receiver, trustee, custodian or other similar official for it or for any
substantial part of its property and, in the case of any such proceeding
instituted against it (but not instituted by it), either such proceeding shall
remain undismissed or unstayed for a period of 60 days, or any of the actions
sought in such proceeding (including, without limitation, the entry of an order
for relief against, or the appointment of a receiver, trustee, custodian or
other similar official for, it or for any 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

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

or order is covered by a valid and binding policy of insurance between the

or enforceable against any party to it (other than the Administrative Agent or
any Lender), or any such party shall so state in writing.

then, and in any such event, the Administrative Agent (i) shall at the request,
or may with the consent, of the Majority 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 Majority 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 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 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.

                                   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

                                                                              25

<PAGE>   26

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 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

                                                                              26

<PAGE>   27

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.

                                  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 BBVAPR and Affiliates. With respect to its Commitment, the
Advances made by it and the Note or Notes issued to it, BBVAPR 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 BBVAPR in its
individual capacity. BBVAPR 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

                                                                              27

<PAGE>   28


any Person who may do business with or own securities of any Loan Party or any
of its Subsidiaries, all as if BBVAPR were not the Administrative Agent and
without any duty to account therefor 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 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.

                                   ARTICLE IX
                                  MISCELLANEOUS

         SECTION 9.01 Amendments, Etc. No amendment or waiver of any provision
of this Agreement, the Notes or any other Loan Documents, nor consent to any
departure by any Loan Party therefrom, shall in any event be effective unless
the same shall be in writing and signed by the Majority Lenders, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver
or consent shall, unless in writing and signed by all the Lenders, do any of the
following at any time: (i) waive any of the conditions specified in Article III,
(ii) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Notes or the Advances or the number of Lenders that
shall be required for the Lenders or any of them to take any action hereunder,

subject the Lenders to any additional obligations, (v) reduce the principal of,
or

                                                                              28

interest on, the Notes, or any fees or other amounts payable hereunder, (vi)
postpone any date fixed for any payment of principal of, or interest on, the
Notes or any fees or other amounts payable hereunder, (vii) limit the liability
of any party under any Loan Document or (viii) modify the definition of the term
"Majority Lenders"; and provided, further, that no amendment, waiver or consent
shall, unless in writing and signed by the Administrative Agent in addition to
the Lenders required above to take such action, affect the rights or duties of
the Administrative Agent under this Agreement or any other Loan Document.

         SECTION 9.02 Notices, Etc. All notices and other communications
provided for hereunder shall be in writing (including telecopier communication)

Loan Party or the Administrative Agent, at such other address as shall be
designated by such party in a written notice to the other parties and, as to
each other party, at such other address as shall be designated by such party in

executed counterpart of any amendment or waiver of any provision of this
Agreement or the Notes or of any Exhibit hereto to be executed and delivered

thereof.

         SECTION 9.03 No Waiver; Remedies. No failure on the part of any Lender
or the Administrative Agent to exercise, and no delay in exercising, any right
hereunder or under any Note shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

         SECTION 9.04 Costs and Expenses. The Borrower agrees to pay on demand
all reasonable out-of-pocket costs and expenses of the Administrative Agent and
the Lenders 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 and expenses of counsel for the Administrative Agent; provided
that such costs and expenses shall not in the aggregate be in excess of $5,000.
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).

                  (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,

                                                                              30

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.

                  (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 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);

                                                                              31

<PAGE>   32

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 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

                                                                              32
<PAGE>   33


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.

         SECTION 9.10 Jurisdiction, Etc. Each of the Loan Parties hereby agrees
that any suit, action or proceeding with respect to this Agreement or the Notes,
the other Loan Documents 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.

                  (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

                                                                              33

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 Agreement to be executed by their respective officers thereunto duly
authorized, as of the date first above written.
