TO THE CONTRACT OF POTENCY RESERVE AND SUPPLY OF ELECTRIC POWER, according to
the following clauses:

	 	 	 
	1st CLAUSE

	 	The subject matter of this Addendum is to set forth a replacement
of monthly demand of 2500 KW, corresponding to the balance of the
“Compensation of the electric energy block that was not consumed by
TRIKEM-UCS-AL during the scheduled stoppage for maintenance in the period
from 09/22/99 through 09/28/99, as follows:

	 	 	 	 	 	 	 
	

	 	 	.	 	 	The “replacement period”, subject matter of this
addendum, corresponds to the interval from 00:00h of
03/01/2000 through 24:00h of 03/31/2000, and from 00:00h of
05/01/2000 through 24:00h of 12/31/2000. During the
replacement period, subject matter of this addendum, for both
peak and out of peak segments, the following conditions are
agreed:
	 
	 	 	 	 	 	 
	

	 	 	1.	 	 	Consider the demand amounts, contracted for both
peak and out of peak segments, at the present amount, which is
170,000 KW.
	 
	 	 	 	 	 	 
	

	 	 	2.	 	 	The tolerance for calculating the excess demand
is 5% (five percent) of the contract’s value for both peak and
out of peak segment, and corresponds to 8,500 KW
	 
	 	 	 	 	 	 
	

	 	 	3.	 	 	For the replacement period, TRIKEM-UCS-AL’s
consumption history will be observed, where it is verified the
demand record close to the 5% limit over the contract.
	 
	 	 	 	 	 	 
	

	 	 	4.	 	 	The demand amount measured, or equivalent, up to
the limit of 178,000 KW (value historically practiced, updated
to the new value of the contract) will be considered as firm
demand for billing purposes.
	 
	 	 	 	 	 	 
	

	 	 	5.	 	 	The demand amount measured, or equivalent, in
excess of 178,000 KW, up to the limit of 180,500 KW, will be
deemed to be replacement demand, which will not be billed.
	 
	 	 	 	 	 	 
	

	 	 	6.	 	 	The demand amount measured, or equivalent, in
excess of 180,500 KW, up to the limit of 181,000 KW, will be
considered as firm demand for billing purposes.
	 
	 	 	 	 	 	 
	

	 	 	7.	 	 	If the limit of 181,000 KW (contract demand plus
replacement demand plus tolerance limit) is exceeded, the
demand amount measured, or equivalent, in excess of 172,500 KW
(contracted demand plus replacement demand) will be considered
as excess for billing purposes

 

 

	 	 	 	 	 	 	 
	

	 	 	8.	 	 	The consumption effectively measured, or
equivalent, will be considered as firm for billing purposes.
	 
	 	 	 	 	 	 
	

	 	 	9.	 	 	In the case of operational restrictions, CHESF
might request the return of demand to the contract’s level,
without such event implying in postponement of this addendum,
or any other kind of compensation by CHESF.

	 	 	 
	2nd CLAUSE

	 	The other clauses in the contract hereby appended, remain
unchanged with respect to all provisions that do not expressly or
implicitly are conflicting herewith.

Being thus agreed, the parties sign this instrument on 3 (two) copies of equal
content and configuration, in the presence of the witnesses indicated.
