(this term to be defined below), the said payment shall be made on the Working
Day immediately following, the interest to be recalculated accordingly.

For the purposes of this contract:

A "WORKING DAY" shall be deemed to mean, leaving aside Saturdays, Sundays or
holidays, any day on which the main offices of the credit institutions in
Mexico, the City of London, England and New York City, N.Y., United States of
America, are open to the public for the carrying out of banking operations.

The "FINAL PAYMENT DATE" shall be deemed to mean the expiry of the period during
which this contract is in force.

The "INTEREST PAYMENT DATE" shall be deemed to mean the first date of each
Interest Period.

"INTEREST PERIOD" shall be deemed to mean, in respect of the Loan, the number of
calendar days included between each one of the dates on which "THE CLIENT" shall
have the loan available and the Partial Payment Dates which the parties shall
agree upon for the repayment of the Loan, it being understood that the Interest
Periods thus

<PAGE>

defined shall not be less than 2 (two) days and not more than 180 (one hundred
and eighty) days on a basis of which interest which shall give rise to the
outstanding sum total of the principal shall be calculated. Any Interest Period
which is in force on the Final Payment Date shall conclude precisely on the said
date.

The "LIBOR (LONDON INTERBANK OFFERED) RATE" shall mean the annual interest rate
offered by the main banks on the London Interbank market as the rate for
deposits in Dollars for a period of up to 180 days, at approximately 11.00 a.m.
(London time), which shall be published 48 (forty-eight) working hours (in
London, England) before the beginning of each Interest Period on the LIBOR 01
page of the REUTERS INFORMATION SYSTEM, OR ALSO ON THE BTMM PAGE OF THE
BLOOMBERG SYSTEM, both for the deposits in US Dollars or the currency replacing
them, should the said pages cease to be published.

The aforementioned LIBOR rate will be rounded, should the figure arrive at five
decimal places or more, to the nearest figure with four decimal places. For this
purpose, a five shall be rounded up to the ten immediately higher.

Should the Bank of Mexico cease to use the LIBOR rate as the reference rate and
even if it should continue to be published, the Bank of Mexico shall define a
substitution rate for the above mentioned LIBOR rate, starting from the date
established by the bank itself, plus the percentage points indicated above and
with the same calculation system.

Should the Bank of Mexico fail to determine a substitution reference rate for
the LIBOR rate, the Cost of Pick up on credit of Liabilities Denominated in
Dollars (CCP Dollars - to be defined below) shall be used as a substitution
rate, plus at least one percentage point in addition to the figure agreed for
LIBOR, should it occur for some reason that the Bank of Mexico ceases to accept
CCP Dollars as a reference rate, and even if it should continue to be published,
the rate set by the Bank of Mexico as a substitution for this latter shall be
accepted and shall be published on the Working Day immediately prior to the
beginning of the Interest Period in question, plus the percentage points allowed
in the first part of this paragraph.

"CCP Dollars" refers to the Cost of Pick up on Credit of Liabilities denominated
in Bank of Mexico US Dollars which the Bank of Mexico shall calculate and
publish in the Official Gazette of the Federation (Republic of Mexico).

<PAGE>

Should it occur that none of the rates indicated above be published, the parties
are in agreement that a further accord amending this contract shall be signed
the purpose of which shall be to set the rate of interest applicable thereto.
This shall take place within a period of time not longer than 20 (twenty)
calendar days, by which day "BANCOMER" shall have communicated the said
circumstance to "THE CLIENT".

Should the parties not reach an agreement regarding the substituted rate
applicable within the period of time agreed above, this shall be deemed cause
for the early expiry of this contract. In this case "THE CLIENT" shall be
obliged to repay to "BANCOMER" the sum of the Loan outstanding plus additional
sums on the date of the aforementioned expiry, as long as in the contrary case
the outstanding sum shall yield interim interest in accordance with that which
is agreed upon in this instrument, the basis thereto being taken as the most
recent ordinary rate applicable to this Loan.

To calculate the ordinary interest for each Interest Period, the annualized
interest rate applicable shall be divided by 360 (three hundred and sixty) and
the result multiplied by the number of calendar days which compose the Interest
Period in question. The resulting rate shall be multiplied by the outstanding
sum of the Loan and the product shall be sum which "THE CLIENT" shall pay to
"BANCOMER" by way of interest on every Interest Payment Date.

INTERIM INTEREST.

SEVEN. Should it occur that "THE CLIENT" does not punctually pay any sum of
money he should to "BANCOMER" in accordance with this contract, with the
exception of interest, the said sum of money shall yield interim interest from
the date on which the payment is due until the sum is paid in full. The interest
shall be accrued daily, shall be payable at sight and in accordance with an
annualized rate equal to the figure arrived at by multiplying the ordinary
interest rate by 3 (three).

To calculate interim interest, the annualized interim interest rate applicable
shall be divided by 360 (three hundred and sixty) and the quotient shall be
applied to outstanding and due sums, thus producing the interim interest for
each day, which "THE CLIENT" shall be obliged to pay according to the terms of
this contract.

COMMISSION.

EIGHT. "THE CLIENT" shall be obliged to pay the following to "BANCOMER":
Commission for opening the Loan equivalent to the sum of US $3,000.00 (three
thousand dollars) which shall be paid on the occasion of the first Loan payment.
For the purposes of the above, "THE CLIENT" shall irrevocably empower "BANCOMER"
to collect the said commission, plus the relevant VAT, from the sum of the Loan.

Dollars purchased in the said form shall exceed the sum originally owed to
"BANCOMER", the latter shall repay the surplus to "THE CLIENT".
