<PAGE>

     2.02. Availability of Loan.

     a.   The Loan shall be available to the Borrower in one or more drawings on
          such Banking Day or Banking Days during the Availability Period as may
          be mutually agreed upon by and between the Bank and the Borrower but
          always subject to availability of funds on the agreed date of
          disbursement.

     b.   The Borrower shall deliver to the Bank a Notice of Borrowing at least
          seven (7) Banking Days (to commence to run after the Bank shall have
          determined that all the conditions precedent to the Loan have been
          fulfilled), prior to the date of any borrowing hereunder (which date
          shall be a Banking Day). The Notice of Borrowing shall be in the form
          and substance as may be required by the Bank and shall contain the
          Borrower's certification that as of the date of the borrowing, no
          Event of Default, and no event which, with the giving of notice or the
          passage of time, or both, would constitute an Event of Default, has
          occurred or is continuing, that the representations and warranties of
          the Borrower contained herein will remain to be true and correct as of
          the date of the borrowing and that all conditions precedent required
          hereunder, have been met. The notice of Borrowing once received and
          accepted by the Bank shall be irrevocable and binding on the Borrower.
          Thereafter, in addition to the Bank's other remedies hereunder, the
          Borrower shall have full liability and accountability for any costs
          incurred by the Bank resulting from the Borrower's failure to effect
          the drawing or a failure to satisfy the conditions for such drawing,
          including losses from re-employment of funds obtained for the drawing
          at rates lower than the cost of such funds. The Bank shall certify
          such costs and losses and shall notify the Borrower of the aggregate
          amount thereof, and such costs and losses as determined by the Bank
          shall be binding and conclusive on the Borrower.

     c.   The Bank, at its sole discretion, may waive the required Notice of
          Borrowing.

     2.03. Interest. The Borrower hereby promises to pay on the Interest Payment
Date/s, as stated in Section 2.04(a), interest (computed on the basis of a year
of 365 days and actual days elapsed) on the outstanding balance of the principal
amount of each Loan from the date of each Loan until full payment thereof at the
rate of two point five percent (2.5%) per annum over and above the applicable
Base Rate, plus the applicable final/withholding tax, value added tax and/or
gross receipts tax, if any.

     The Base Rate, to be set on the Interest Payment Date shall be the 90-day
MART 1 Rate.

     The Alternative Base Rate as defined herein shall be used automatically in
lieu, of the Base Rate on the interest payment date if difference between the
90-day PHIBOR and the Base Rate is greater than one hundred fifty (150) basis
points on the actual repricing date.

     The "Alternative Base rate" shall be the average of the latest 90-day MART
1 Rate and the 90-day PHIBOR prevailing on actual repricing date + 2.5% + plus
the applicable final/withholding tax, value added tax and/or gross receipts tax,
if any.

     For purposes of the Loan, Interest Period shall mean each of the successive
periods of three (3) months into which the period between the date of Borrowing
and the last Payment Date

                                        3

<PAGE>

is to be divided. Each Interest Period shall end on the numerically
corresponding day of each third month period after the date of Borrowing (or if
there is no day so corresponding in such month, such Interest Period shall end
on the last day of such month): Provided, that if any Interest Period would
otherwise end on a day which is not a Banking Day, such Interest Period shall be
extended to the next succeding day which is a Banking Day, unless the result of
such extension would be to carry such Interest Period over into another calendar
month, in which event such Interest Period shall end on the immediately
preceding Banking Day.

     In the event that:

          (i) the interest rate to be applied to the Loan for any Interest
     Period cannot be ascertained in accordance with Section 2.03, or

          (ii) the Bank, on or prior to the commencement of any Interest Period,
     shall have determined, whether or not such determination shall be by reason
     of any change in law, rule or regulation or in the interpretation or
     administration thereof and which determination shall be conclusive and
     binding upon the borrower, that the applicable interest rate determined in
     accordance with Section 2.03 does not or will not accurately reflect the
     cost to the Bank of maintaining the Loan(s) during such Interest Period,

the Bank shall promptly give written notice of such event to the Borrower.
Within a period of 30 calendar days following the giving of such notice, the
Borrower and the Bank shall negotiate in good faith with a view toward
ascertaining an alternative mutually satisfactory basis for determining the
interest rate to be applied to the Loan. If within such a 30-day period the
Borrower and the Bank shall have agreed on a substitute interest rate, it shall
be retroactive to and take effect from the first day of the relevant Interest
Period. If within such 30-day period the Borrower and the Bank shall fail to
agree in writing upon such substitute interest rate, then the Borrower shall
prepay the Loan in full, without any prepayment penalty, on the first Banking
Day following the expiry of such 30-day period, but with accrued interest from
the last day of the preceding Interest Period to the date of such prepayment at
the rate applicable for the immediately preceding Interest Period.

     In the event that:

          (i)  any of the principal of the Loan(s) or any installment thereof,
               or

          (ii) any interest due thereon, or

          (iii) any other sum due hereunder or under the Note(s),

shall not be paid in full when due (whether at stated maturity, by acceleration
or otherwise), the Borrower shall pay the Bank a default penalty on any such
amount, whether of principal or of interest or of any and all amounts, from the
due date thereof until payment thereof in full, at a rate of three percent (3%)
per month, or a fraction of a month, above and in addition to the interest rate
payable under this Agreement and the Note(s), and such default penalty shall be
payable from time to time on demand by the Bank.

                                        4

<PAGE>

     Interest not paid when due shall, at the Bank's option and 30 calendar days
after it falls due, be added to and become part of the principal and shall bear
the same rate of interest as the principal.

     2.04. Notes; Repayment.

     a. The Loan shall be for a term of FIVE (5) YEARS years inclusive of a
grace period of ONE (1) YEAR in the payment of amortization in the principal and
shall be evidenced by Note(s) in the amount of such Loan, which Note(s) shall be
dated as of the date of drawing, and be payable with respect to principal and
interest as follows (date of payment called "Payment Date/s"):

          Principal : Payable in sixteen(16) quarterly amortization to commence
                      on the numerically corresponding day at the end of the
                      fifth (5th) quarter from the date of initial borrowing and
                      every numerically corresponding day of each third month
                      thereafter (or if there is no day so corresponding in such
                      month, the last day of the month), until full payment of
                      the Loan.

          Interest  : Payable quarterly in arrears in accordance with the rate
                      provided in Section 2.03 of this Agreement, to commence on
                      the numerically corresponding day of the third month from
                      the date of initial borrowing and every numerically
                      corresponding day of each third month thereafter (or if
                      there is no day so corresponding in such month, the last
                      day of such month), until full payment of the Loan.

     b. All sums payable to the Bank hereunder or under any document
contemplated herein, including but not limited to payments of interest and
principal, other fees and any costs, losses, indemnities or expenses, shall be
payable in cleared funds in the currency in which the Loan was obtained not
later than 12:00 noon of the due date(s) of such amount(s).

     c. Any payment made to the Bank hereunder shall be applied first against
costs, expenses, losses and indemnities due hereunder, then against fees due to
the Bank, then against default penalty, if any, then against interest due on the
Loan(s), then against the Loan(s) due and payable, and thereafter to the
prepayment of the Loan(s) in accordance with Section 2.06.

     2.05. Consolidation of Notes; Cancellation; Adjustment. If and as the Bank
shall from time to time request, the Borrower shall execute and deliver to the
Bank a replacement note (for purposes only of this Section 2.05, the
"Replacement Note") in the aggregate principal amount of the Loan(s) which shall
have been disbursed by the Bank and shall be outstanding at the time of such
request. Upon the delivery of such Replacement Note, any note which shall have
been issued or delivered to the Bank shall be canceled and, in addition,
appropriate adjustments shall be made so that there shall be no loss to the Bank
or to the Borrower in respect of any principal of the Loan or the interest
thereon. The issuance of the Replacement Note shall not be construed as a
novation with respect to the Loan(s).

                                        5

subject to the following conditions:

     a.   the Borrower shall give at least thirty (30) calendar days irrevocable
          prior written notice to the Bank of the amounts and the date (which
          shall be a Banking Day) of such prepayment;

     b.   for loans with multiple interest payment dates, each prepayment shall
          be made on an interest payment date;

     c.   prepayment shall be in minimum multiples of PESOS: ONE MILLION
          (PHP1,000,000.00);

     d.   the Borrower shall pay accrued interest on the amount prepaid and any
          incremental tax;

     e.   for installment loans, each partial prepayment shall be applied to the
          principal amount of installments in the inverse order of their
          maturity (i.e., to the last maturing installment or installments of
          principal) or, at the sole option of the Bank, to installments of
          principal and interest succeeding the date of prepayment; and

     f.   amounts paid may not be reborrowed hereunder.

     2.07. Conclusiveness of Bank's Books. The books of the Bank shall be deemed
final and conclusive evidence concerning the amount due it from the Borrower..

SECTION 3. FUNDING AND YIELD PROTECTION

     3.01. Taxes.

     a. All payments due to the Bank hereunder or under the Notes, whether of
principal, interest, penalties, fees or otherwise, shall be made without set-off
or counterclaim, and free and clear of and without any deduction or withholding
on account of any taxes (including, without limitation, the final or withholding
tax on interest payable to the Bank hereunder and gross receipts tax and/or
value-added tax thereon), all of which shall be for the account of the Borrower
and paid by it directly to the relevant taxing or other authority when due. If
the Borrower shall be required by law to make any deduction or withholding in
respect of taxes from any payment hereunder, the sum payable shall be increased
as will result in the receipt by the Bank, after such deduction or withholding,
of the amount that would have been received if such deduction or withholding had
not been required. Whether by voluntary or involuntary pretermination or
acceleration of the Loan, the Borrower shall be liable to pay any resulting tax
deficiencies, penalties, surcharges and incremental taxes on the Gross Receipts
Tax, as well as on all other applicable taxes that may be imposed.

     b. The Borrower shall forward to the Bank copies of official receipts or
other evidence acceptable to the Bank establishing the rate and payment of taxes

     c. The Borrower's obligations under this Subsec. 3.01 shall survive the
repayment of the Loan to the extent that the obligations hereunder have not been
fully discharged by the Borrower to the prejudice of the Bank.

     3.02. Change in Circumstances. In the event that there shall hereafter
occur any change in any applicable law or regulation which shall increase (i)
the cost to the Bank of maintaining any reserves or special deposits against the
Loan or (ii) any other cost of complying with any law, regulation or condition
with respect to such Loan, and the result of any of the foregoing is to increase
the cost to the Bank of making or maintaining the Loan or to reduce the amount
of any payment (whether of principal, interest or otherwise) receivable by the
Bank hereunder, then the Borrower shall pay or reimburse to the Bank such amount
as will compensate it for such additional cost or reduction of payment.

     3.03. Change in Regulations. Notwithstanding anything to the contrary
contained herein, in the event that there shall hereafter occur any change in
applicable law or regulation or in the interpretation or administration thereof,
which shall make it unlawful for the Bank to maintain or give effect to its
obligations as contemplated under this Agreement or to receive the intended
benefits of this Agreement, then by written notice to the Borrower, the Bank may
(i) declare its obligation to lend hereunder terminated, and it shall thereby be
terminated, and (ii) require payment immediately of the principal amount of the
Loan then outstanding as well as accrued interest thereon together with such
additional amounts as may be necessary to compensate the Bank from loss
pertaining to the cost of re-employment of funds so repaid at rates lower than
the cost to the Bank of such funds. The Bank shall certify the aggregate amount
of such losses and costs to the Borrower (which certification shall include a
reasonably detailed description of such costs and expenses) and such
certification shall be binding and conclusive on the Borrower.

     3.04. Funding Costs and Losses. The Borrower shall indemnify the Bank
against any cost or loss in connection with the unwinding or liquidating of any
deposits, funding or financing arrangement that the Bank may in good faith incur
as a result of (i) any Loan not being made by the Bank due to the failure of the
Borrower to satisfy the conditions specified in Sec. 6 on the proposed date of
borrowing, or (ii) any prepayment or repayment of the Loan of the Bank on a date
that is not an Interest Payment Date.

     h.   There shall have occurred a material change in the business assets or
          financial circumstances or condition of the Borrower (including,
          without limitation, the making of any investment unrelated to the
          Borrower's business, excessive losses due to having made unnecessary
          investments or having exposed itself to unnecessary risks, the
          undertaking of a major expansion program or permitting earnings before
          interest and taxes to fall below a level which would be necessary to
          service the interest expense on present and future loan obligation)
          which, in the reasonable opinion of the Bank, would adversely affect
          the ability of the Borrower to perform its obligations under this
          Agreement and the Note; or

     i.   In the reasonable opinion of the Bank, the Borrower shall have
          abandoned the Project or the completion thereof, whether such
          abandonment shall have occurred within the Availability Period or
          during the effectivity of this Agreement; or

     j.   Any adverse circumstances occurs, which in the reasonable opinion of
          the Bank, materially or adversely affects the ability of the Borrower
          to perform its obligations under this Agreement; or

     k.   Any of the events of default enumerated in the Note shall occur; or

     l.   An attachment or garnishment of or levy upon any of the properties of
          the Borrower is made; or

     m.   The Collateral or any document related thereto or any other document
          which serves as security for the Loan shall for any reason (at any
          time after their execution and delivery) become ineffective, impaired
          or cease to be in full force and effect or declared null and void or
          the applicability thereof to the Loan is disaffirmed by the Borrower,
          or any right or lien established or created in favor of the Bank in
          and under the Collateral is lost or otherwise impaired;

then, and in any such event, the Bank may by written notice to the Borrower
declare all amounts owing to the Bank under this Agreement/the Note, whether of
principal, interest or otherwise, to be forthwith due and payable, whereupon all
such amounts shall become immediately due and payable without demand or other
notice of any kind, all of which are expressly waived by the Borrower, provided,
that no such declaration of amounts due and payable shall be necessary in case
of an event of default under Section 8(a) and 8(d) upon the occurrence of which
default the whole principal sum and/or all installments thereof, together with
accrued interest and all other charges and penalties due thereon, shall
immediately become due and payable without demand or notice of any kind, all of
which the Borrower expressly waives. The Borrower shall pay on demand by the
Bank, in respect of any amount or principal paid in advance of stated maturity
pursuant to this Section 8, a prepayment penalty equal to three per cent (3%) of
the amount prepaid.
