CLAUSE ELEVEN. COMMITMENT TO GOALS AND INVESTMENTS

In order to adequately provide the services awarded to the GRANTEE, the
following expansion goals must be met:

      (a)   elevate the level of coverage of the water supply service to 100%
            (one hundred percent) by December 31, 2004, maintaining that level
            during the remaining term of the concession;
      (b)   elevate the level of attention to wastewater collection and
            treatment to a minimum of: (i) 82.1% (eight-two point one percent)
            by December 31, 2004; (ii) 86.1% (eighty six point one percent) by
            December 31, 2015; and (iii) 90% (ninety percent) on December 31,
            2020, maintaining that level during the remaining term of the
            concession.

Development -- will be used for calculation of the goals in the preceding
subparagraph.

ss. 2. A deviation of 0.2% (zero point two percent) is acceptable for the
percentages in that subparagraph.

ss. 3. Insofar as the assured return on the employed capital, compatible with
the average obtained in the rest of the concession area, as measured in the six
(6) months immediately prior, is determined to be important to the public
interest, the GRANTOR may direct the GRANTEE, within a reasonable period, to
begin to provide the awarded service in areas that do not have a functioning
water distribution and wastewater collection system, or to begin to respond to
the needs of special consumers.

ss. 4. The GRANTOR, for the purpose of guaranteeing the return referred to in
paragraph 3, may participate in the investment to be made.

ss. 5. Whether or not the GRANTOR participates in the investment, inasmuch as
the return on the employed capital referred to in paragraph 3 is assured, the
failure of the GRANTEE to respond to the order will mean the immediate loss of
contractual exclusivity in the area covered by the order, and the GRANTOR may,
if it sees fit, begin to provide the service directly itself or through a new
concession for the area, or the partial subcontracting of the already existing
concession, under conditions for provision of service that are equal to those
offered to the GRANTEE, guaranteeing to the latter adequate remuneration for the
use of its system of distribution or collection by the new grantee, or
subcontractor, as the case may be. The decision of the GRANTOR, to be effective,
must delimit the area to be served.

condominium will be authorized by the GRANTOR only when the projects for water

declare any property that is needed for the installation or expansion of water
and sewer systems to be of public utility.

and financial records and technical studies, which may not be denied without
reasonable justification. The GRANTOR may, in addition, request from the GRANTEE
any information or data necessary for verifying the correct performance of this
Agreement, and will maintain the confidentiality of any and all information
acquired under these circumstances.

ss. 3. The technical inspection of the services includes the construction
projects, the plants and the operation of the services.

ss. 4. Accounting oversight will include the examination of all the pertinent
bookkeeping entries, records and accounting documents of the GRANTEE. For

the investments that are made, the bases of depreciation and amortization, and
the appropriateness of costs per activity, zone and consumer category.

ss. 6. For the purposes of that which is contained in the preceding paragraph,
the GRANTEE, within twelve (12) months subsequent to the signing of this

receipt thereof, the Chart presented by the GRANTEE will become effective.

ss. 7. Changes may be made to the Chart of Accounts upon the duly justified
request of the GRANTEE to the GRANTOR, whose responsibility it is to decide upon
the matter. The changes may also be made at the decision, for good reason, of
the GRANTOR, after a prior hearing of the GRANTEE.

ss.8. The annual financial statements of the GRANTEE will be submitted to an
independent external auditor.

ss. 9. Inspection by the GRANTOR does not absolve the GRANTEE of its
responsibility for the adequacy of its projects and facilities and does not
extend to the correctness and legality of the latter's accounting records and
financial and commercial operations.

ss. 10. Failure of the GRANTEE to respond to the requests, recommendations and
directions of the GRANTOR will result in the application of the penalties
defined in this Agreement, with the GRANTEE being guaranteed the right to defend
itself fully.

CLAUSE TWENTY-FOUR. TERMINATION OF THE CONCESSION AND REVERSION OF THE ASSETS
ENTAILED

This Agreement will be terminated by:

I. the end of the term of the Agreement;
II. the cancellation of the services;
III. expiration;
IV. revocation;
V. annulment;
VI. the death or termination of the GRANTEE.

ss. 1. Under the law, the ending of the term of the Agreement results in the
termination of the concession, and the GRANTOR is permitted, at its sole
discretion, to keep the GRANTEE as the provider of services, until the bidding
for the award of a new concession has been processed.

ss. 2. Under the law, termination of the concession will result in the reversion
to the GRANTOR of the pledged assets and the prerogatives conferred on the
GRANTEE, by means of the prior indemnification of the GRANTEE, calculated in
accordance with the value of those assets, based on the Chart of Accounts,
without including for such purposes that share of the asset base that is already
depreciated.

ss. 3. In the event that the concession is cancelled before completion of the
term of the Agreement, through no fault of the GRANTEE, the latter may attempt
to recover, as lost profits, an amount equal to the average of the cash profits
of the GRANTEE, calculated in accordance with the corporations law and based on
the five years preceding the termination, for each year remaining before the
aforementioned end of the term of the Agreement. For purposes of determining the
average set forth in this paragraph, the profit of each financial period
included will be updated to reflect current monetary values, based on the IPC
[Consumer Price Index] published by the IBGE, for the data upon which the
indemnification for lost profits will be calculated.

ss. 4. In the event that any of the instances of non-compliance provided for in
the specific legislation of this Agreement are verified, the GRANTOR will file
for a declaration of forfeiture of the concession, using the appropriate legal
form.

ss. 5. Declaration of forfeiture of the concession will be preceded by an
administrative proceeding for the verification of the infractions or omissions,
and the GRANTEE will reserve the right to full defense.

ss. 6. The administrative proceeding mentioned above will not be initiated until
the GRANTEE has received due notice, which will include a complete and detailed
description of the contractual violations it has incurred, and has been given a
reasonable period to remedy such violations.

ss. 7. Pursuant to the preceding paragraph, the declaration of forfeiture will
involve no liability for the GRANTOR in connection with any liabilities,
obligations or agreements with third parties with which the GRANTEE may have
contracted, or with its employees.

ss. 8. Through legal action specifically intended for this purpose, the GRANTEE
may file for the rescission of this Agreement in the event that the GRANTOR
fails to comply with the legal or contractual provisions. In this case, the
GRANTEE will not interrupt services until the court has processed the legal
ruling ordering the termination of the Agreement.

CLAUSE TWENTY-FIVE. DELEGATION OF THE POWERS OF THE GRANTOR
