comprised of Eurodollar Rate Advances and shall be made on notice, given not
later than 11:00 A.M. (Dusseldorf time) one Business Day prior to the date of
the proposed Borrowing to the Agent (the "Notice of Borrowing") which shall be

available for the account of its Lending Office to the Agent at the Agent's
Account, in same day funds, such Lender's ratable portion of such Borrowing.
After the Agent's receipt of such funds and upon fulfillment of the applicable
conditions set forth in Article III, the Agent will make such funds available to
the Borrower at the Agent's address referred to in Section 8.02.

                  (b) The Notice of Borrowing shall be irrevocable and binding
         on the Borrower. In the case of any Borrowing that the related Notice
         of Borrowing specifies is to be comprised of Eurodollar 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 Borrowing for such
         Borrowing the applicable conditions set forth in Article III,
         including, without limitation, any loss, cost or expense incurred by
         reason of the liquidation or reemployment of deposits or other funds
         acquired by such Lender to fund the Advance to be made by such Lender
         as part of such Borrowing when such Advance, as a result of such
         failure, is not made on such date.

                  (c) Unless the Agent shall have received notice from a Lender
         prior to the date of any Borrowing that such Lender will not make
         available to the Agent such Lender's ratable portion of such Borrowing,
         the Agent may assume that such Lender has made such portion available
         to the Agent on the date of such Borrowing in accordance with
         subsection (a) of this Section 2.02 and the 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 Agent, such Lender
         and the Borrower severally agree to repay to the 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 Agent, at (i) in the case
         of the Borrower, the interest rate applicable at the time to Advances
         comprising such Borrowing and (ii) in the case of such Lender, the
         Federal Funds Rate. If such Lender shall repay to the Agent such
         corresponding amount, such amount so repaid shall constitute such
         Lender's Advance as part of such Borrowing for purposes of this
         Agreement.

                  (d) The failure of any Lender to make the Advance to be made
         by it as part of any Borrowing shall not relieve any other Lender of
         its obligation, if any, hereunder to make its Advance on the date of
         such Borrowing, but no Lender shall be responsible for the failure of
         any other Lender to make the Advance to be made by such other Lender on
         the date of any Borrowing.

                  (e) Borrowings used to pay accrued and unpaid interest when
         due may only be made on the day such interest is due and payable, for
         the amount of such interest.

                           (ii) Eurodollar Rate Advances. During such periods as
                  such Advance is a Eurodollar Rate Advance, a rate per annum
                  equal at all times during each Interest Period for such
                  Advance to the sum of (x) the Eurodollar Rate for such
                  Interest Period for such Advance plus (y) the Applicable
                  Margin 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
                  Eurodollar Rate Advance shall be Converted or paid in full.

         continuance of an Event of Default, the Borrower shall pay interest on
         (i) the unpaid principal amount of each Advance owing to each Lender,
         payable in arrears on the dates referred to in clause (a)(i) or (a)(ii)
         above, at a rate per annum equal at all times to 2% per annum above the
         rate per annum required to be paid on such 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

         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 Base Rate Advances pursuant to clause (a)(i) above.

                  (c) Capitalized Interest. The Borrower may notify the Agent at

   16

         on the Maturity Date, that the amount of interest payable on such
         Applicable Interest Payment Date shall be added to the principal amount
         of the Advances. So long as on the date of such notice and the
         Applicable Interest Payment Date no Default or Event of Default has
         occurred and is continuing, the amount of such interest shall be added
         to the outstanding principal amount of the Advances on the Applicable
         Interest Payment Date and for all purposes shall be deemed to
         constitute part of the principal amount of the Advances as of such
         date.

                  SECTION 2.06. Interest Rate Determination. (a) The Agent shall
give prompt notice to the Borrower and the Lenders of the applicable interest
rate determined by the Agent for purposes of Section 2.05(a)(i) or (ii).

                  (b) If, with respect to any Eurodollar Rate Advances, the
         Required Lenders notify the Agent that the Eurodollar Rate for any
         Interest Period for such Advances will not adequately reflect the cost
         to such Required Lenders of making, funding or maintaining their
         respective Eurodollar Rate Advances for such Interest Period, the Agent
         shall forthwith so notify the Borrower and the Lenders, whereupon (i)
         each Eurodollar 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
         Advances into, Eurodollar Rate Advances shall be suspended until the

         causing such suspension no longer exist.

                  (c) If the Borrower shall fail to select the duration of any
         Interest Period for any Eurodollar Rate Advances in accordance with the
         provisions contained in the definition of "Interest Period" in Section
         1.01 and there shall be less than one month between the date of such
         failure and the Maturity Date, the Agent will forthwith so notify the

         last day of the then existing Interest Period therefor, Convert into
         Base Rate Advances.

                  (d) On the date on which the aggregate unpaid principal amount
         of Eurodollar Rate Advances comprising any Borrowing shall be reduced,
         by payment or prepayment or otherwise, to less than $5,000,000, such
         Advances shall automatically Convert into Base Rate Advances.

                  (e) Upon the occurrence and during the continuance of any
         Event of Default, (i) each Eurodollar 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 Advances into, Eurodollar Rate Advances shall be
         suspended.

         $75,000,000 received by the Borrower from financings for the Borrower

organized or has its 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 Agent), pay to the Agent for the account of such Lender
additional amounts sufficient to compensate such Lender for such increased cost.
A certificate as to the amount of such increased cost, submitted to the Borrower
and the Agent by such Lender, shall be conclusive and binding for all purposes,
absent manifest error.

                  (b) If any Lender determines that compliance with any law or
         regulation or any 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
         and that the amount of such capital is increased by or based upon the
         existence of such Lender's commitment to lend hereunder and other
         commitments of this type, then, upon demand by such Lender (with a copy
         of such demand to the Agent), the Borrower shall pay to the 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 in the light of such circumstances, to the extent that such
         Lender reasonably determines such increase in capital to be allocable
         to the existence of such Lender's commitment to lend hereunder. A
         certificate as to such amounts submitted to the Borrower and the Agent
         by such Lender shall be conclusive and binding for all purposes, absent
         manifest error.

                  SECTION 2.09. Illegality. Notwithstanding any other provision
of this Agreement, if any Lender shall notify the 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 asserts that it is
unlawful, for any Lender or its Lending Office to perform its obligations
hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar
Rate Advances hereunder, (i) each Eurodollar Rate Advance will automatically,
upon such demand, Convert into a Base Rate Advance and (ii) the obligation of
the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall
be suspended until the Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

                  SECTION 2.10. Payments and Computations. (a) The Borrower
shall make each payment hereunder and under the Notes not later than 11:00 A.M.
(Dusseldorf time) on the day when due in U.S. dollars to the Agent at the
Agent's Account in same day funds. The 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 2.08, 2.11
or 8.04(c)) to the Lenders for the account of their respective 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 Lending Office, in each case to be applied
in accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(d), from and after the effective date
specified in such Assignment and Acceptance, the Agent shall make all payments
hereunder and under the Notes in respect of the interest assigned thereby to the
Lender assignee thereunder, and the parties to such Assignment and Acceptance
shall make all appropriate adjustments in such payments for periods prior to
such effective date directly between themselves.

                  (b) The Borrower hereby authorizes each Lender, if and to the
         extent payment owed to such Lender is not made when due hereunder or
         under the Note held by such



                                       18
   19

         Lender, to charge from time to time against any or all of the
         Borrower's accounts with such Lender any amount so due.

                  (c) All computations of interest based on the Base Rate shall
         be made by the Agent on the basis of a year of 365 or 366 days, as the
         case may be, and all computations of interest based on the Eurodollar
         Rate or the Federal Funds Rate and of facility fees shall be made by
         the 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 Agent of an interest rate
         hereunder shall be conclusive and binding for all purposes, absent
         manifest error.

                  (d) 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
         Eurodollar Rate Advances to be made in the next following calendar
         month, such payment shall be made on the next preceding Business Day.

                  (e) Unless the Agent shall have received notice from the
         Borrower prior to the date on which any payment is due to the Lenders
         hereunder that the Borrower will not make such payment in full, the
         Agent may assume that the Borrower has made such payment in full to the
         Agent on such date and the 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 Agent, each Lender
         shall repay to the 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 Agent, at the Federal Funds Rate.

                  (f) The making of an Advance to the Borrower, and all payments
         of principal and interest hereunder by the Borrower shall be made to or
         by the Borrower in New York.

                  SECTION 2.11. Taxes. (a) Any and all payments by the Borrower
hereunder or under the Notes shall be made, in accordance with Section 2.10,
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, excluding, in the case of each Lender and the Agent, taxes
imposed on its overall net income, and franchise taxes imposed on it in lieu of
net income taxes, by the jurisdiction under the laws of which such Lender or the
Agent (as the case may be) is organized or any political subdivision thereof
and, in the case of each Lender, taxes imposed on its overall net income, and
franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction
of such Lender's Lending Office or any political subdivision thereof (all such



                                       19
   20

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"). 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 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 2.11) such Lender or
the 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.

                  (b) In addition, the Borrower shall pay any present or future
         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) The Borrower shall indemnify each Lender and the Agent for
         and hold it harmless against the full amount of Taxes or Other Taxes
         (including, without limitation, taxes of any kind imposed by any
         jurisdiction on amounts payable under this Section 2.11) imposed on or
         paid by such Lender or the Agent (as the case may be) and any liability
         (including penalties, interest and expenses) arising therefrom or with
         respect thereto. This indemnification shall be made within 30 days from
         the date such Lender or the Agent (as the case may be) makes written
         demand therefor.

                  (d) Within 30 days after the date of any payment of Taxes, the
         Borrower shall furnish to the Agent, at its address referred to in
         Section 8.02, the original or a certified copy of a receipt evidencing
         such payment.

                  (e) Each Lender, from time to time as requested in writing by
         the Borrower, shall provide the Borrower as soon as practicable, but
         only if and to the extent such Lender is lawfully able to do so, with
         such documents certificates, forms which the Borrower has supplied to
         the Lender for completion and such other information as the Borrower
         may reasonably request from time to time certifying that such Lender is
         exempt from or entitled to a reduced rate of withholding tax on
         payments pursuant to this Agreement or the Note or otherwise to
         establish that such Lender is legally entitled to receive payments
         under this Agreement free of any withholding Taxes and to what extent,
         if any, such payments are subject to any withholding Taxes.

                  (f) For any period with respect to which a Lender has failed
         to provide the Borrower with such appropriately completed forms or
         other information as such Lender is lawfully able to provide and as may
         be required under subsection (e) above, such Lender



                                       20
   21

         shall not be entitled to indemnification under Section 2.11(a) or (c)
         with respect to Taxes that are imposed as a consequence of such
         failure.

                  SECTION 2.12. 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 owing to it (other
than pursuant to Section 2.08, 2.11 or 8.04(c)) 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 participation in the
Advances owing to 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 (i) the amount of such Lender's required
repayment to (ii) 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 2.12
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.

                  SECTION 2.13. Use of Proceeds. The proceeds of the Advances
shall be available (and the Borrower agrees that it shall use such proceeds)
solely to finance (a) a portion of the purchase price of the Concession, in the
case of the initial Borrowing, (b) interest payable to the Lenders hereunder, in
the case of any Borrowings other than the initial Borrowing and (c) any
transaction cost incurred by the Borrower in connection with this Agreement.

         Borrower enforceable against the Borrower in accordance with their
         respective terms, subject to applicable bankruptcy, insolvency or other
         similar laws affecting creditors' rights generally.

                  (e) There is no pending or, to the best of the Borrower's
         knowledge, threatened action, suit, investigation, litigation or
         proceeding affecting the Borrower before any court, governmental agency
         or arbitrator that (i) could be reasonably likely to have a Material
         Adverse Effect or (ii) purports to affect the legality, validity or
         enforceability of this Agreement or any Note or the consummation of the
         transactions contemplated hereby.

                  (f) The Borrower is not 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.

                  (g) The Borrower is not an "investment company" or an
         "affiliated person" of, or "promoter" or "principal underwriter" for,
         an "investment company," as such terms are defined in the Investment
         Company Act of 1940, as amended. Neither the making of any Advances,
         nor the application of the proceeds or repayment thereof by the
         Borrower, nor consummation of the financing contemplated under the Loan
         Documents, will violate any provision of such Act or any rule,
         regulation or order of the Securities and Exchange Commission
         thereunder.

                  (h) This Agreement, the Notes and the other Loan Documents are
         in proper legal form under the law of Argentina for the enforcement
         thereof against the Borrower under the law of Argentina, and to ensure
         the legality, validity, enforceability or admissibility in evidence of
         this Agreement, the Notes and the other Loan Documents in Argentina, it
         is not necessary that this Agreement, the Notes or any other Loan
         Document or any other document be filed or recorded with any court or
         other authority in Argentina.

                  SECTION 4.02. Representations and Warranties of the Lenders.
Each Lender party hereto represents and warrants (1) that it qualifies as a
German resident under the treaty between Argentina and the Republic of Germany
for the avoidance of double taxation (as approved by Argentine Law 22.025;
hereinafter the "Treaty"); (2) that such Lender does not have permanent
establishment in Argentina or does not perform in Argentina professional
services from a fixed base situated therein, and the Advances under this Credit
Agreement in respect of which interest shall be paid shall not be effectively
connected with such permanent establishment or fixed base; and (3) that in
accordance with applicable German Law, it qualifies as a bank under applicable
German Law in furtherance of Section 11(2)(a) of the Treaty.


                                   ARTICLE V

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

                  (a) Compliance with Laws, Etc. Comply in all material
         respects, with all applicable laws, rules, regulations and orders,
         except for a noncompliance which would not have a Material Adverse
         Effect.

                  (b) Preservation of Corporate Existence, Etc. Preserve and
         maintain its corporate existence including maintaining required
         capitalization under Argentine law, rights (charter and statutory) and
         franchises; provided, however, that the Borrower shall not be required
         to preserve any right or franchise if the Board of Directors of the
         Borrower shall determine that the preservation thereof is no longer
         desirable in the conduct of the business of the Borrower and that the
         loss thereof is not disadvantageous in any material respect to the
         Borrower or the Lenders. Notwithstanding anything else provided herein,
         the Borrower shall, not later than the 60th day after the date hereof,
         cause the Borrower to be registered as required under Argentine law in
         accordance with paragraph four of Section 8.1 of the Bidding Terms of
         the National and International Public Bid for the Concession of the
         Water and Sewage Services in the Province of Buenos Aires provided that
         the Borrower shall notify the Agent 30 days after the date hereof
         indicating the status of such registrations, and otherwise from time to
         time in the event that in the reasonable opinion of the Borrower such
         registration may not be achieved as required hereunder.

         remain unpaid or any Lender shall have any Commitment hereunder, the
         Borrower will furnish to the Agent for distribution to the Lenders:

                  statement of an officer of the Borrower setting forth details
                  of such Default and the action that the Borrower has taken and
                  proposes to take with respect thereto.

                           (ii) Other Financings. The Borrower shall notify the
                  Agent at least 10 days prior to any receipt of cash proceeds
                  from any other financing of indebtedness; the proceeds are of
                  the type which could be used to prepay the Advances pursuant

         any Lender; or

                  (e) Any Loan Party shall generally not pay its debts as such

         creditors; or any proceeding shall be instituted by or against any



                                       27
   28

         Loan Party seeking to adjudicate it a bankrupt or insolvent, or seeking
         liquidation, winding up, reorganization, arrangement, adjustment,

         actions set forth above in this subsection (e); or

                  (f) Any judgment or order for the payment of money in excess
         of $10,000,000 shall be rendered against any Loan Party and either (i)
         enforcement proceedings shall have been commenced by any creditor upon
         such judgment or order or (ii) there shall be any period of 10
         consecutive days during which a stay of enforcement of such judgment or

         effect; provided, however, that any such judgment or order shall not be
         an Event of Default under this Section 6.01(e) if and for so long as

consent, of the Required 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 Required 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
applicable bankruptcy laws, (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

                                    THE AGENT

                  SECTION 7.01. Authorization and Action. Each Lender hereby
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers and discretion under this Agreement as are delegated to
the 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 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 Required Lenders, and such instructions shall be binding upon all Lenders
and all holders of Notes; provided, however, that the Agent shall not be
required to take any action that exposes the Agent to personal liability or that
is contrary to this Agreement or applicable law. The 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 7.02. Agent's Reliance, Etc. Neither the 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 Agent: (i) may treat
the payee of any Note as the holder thereof until the Agent receives and accepts
an Assignment and Acceptance entered into by the Lender that is the payee of
such Note, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 8.07; (ii) 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; (iii)
makes no warranty or representation to any Lender and shall not be responsible
to any



                                       29
   30

Lender for any statements, warranties or representations (whether written or
oral) made in or in connection with this Agreement; (iv) 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; (v)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of, or the
perfection or priority of any lien or security interest created or purported to
be created under or in connection with, this Agreement or any other instrument
or document furnished pursuant hereto; and (vi) 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 7.03. WestLB and Affiliates. With respect to its
Commitment, the Advances made by it and the Note issued to it, WestLB 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 Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include WestLB in its
individual capacity. WestLB 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, the
Borrower, any of its Subsidiaries and any Person who may do business with or own
securities of the Borrower or any such Subsidiary, all as if WestLB were not the
Agent and without any duty to account therefor to the Lenders.

                  SECTION 7.04. Lender Credit Decision. Each Lender acknowledges
that it has, independently and without reliance upon the Agent or any other
Lender and based on the financial statements referred to in Section 3.01 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 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 7.05. Indemnification. The Lenders agree to indemnify
the Agent (to the extent not reimbursed by the Borrower), ratably according to
the respective principal amounts of the Notes then held by each of them (or if
no Notes are at the time outstanding or if any Notes are held by Persons that
are not Lenders, ratably according to the respective amounts of 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 Agent in any way relating to or arising out of this
Agreement or any action taken or omitted by the Agent under this Agreement
(collectively, the "Indemnified Costs"), provided that no Lender shall be liable
for any portion of the Indemnified Costs resulting from the Agent's gross
negligence or willful misconduct. Without limitation of the foregoing, each
Lender agrees to reimburse the Agent promptly upon demand for its ratable share
of any out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the



                                       30
   31

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 Agent is not reimbursed for such expenses by the
Borrower. In the case of any investigation, litigation or proceeding giving rise
to any Indemnified Costs, this Section 7.05 applies whether any such
investigation, litigation or proceeding is brought by the Agent, any Lender or a
third party.

                  SECTION 7.06. Successor Agent. The 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 Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Agent having a combined capital and surplus of at least
$150,000,000,000. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation or the Required Lenders'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be a commercial bank organized
under the laws of the United States of America or of any State thereof and
having a combined capital and surplus of at least $150,000,000,000 and shall be
reasonably acceptable to the Pledgor. Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, discretion, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations under this Agreement. After any retiring Agent's
resignation or removal hereunder as Agent, the provisions of this Article VII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent under this Agreement.



                                  ARTICLE VIII

                                  MISCELLANEOUS

                  SECTION 8.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Notes, nor consent to any departure by the
Borrower therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Borrower and the Required 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: (a) waive any of the conditions specified in Section 3.01, (b)
increase the Commitments of the Lenders or subject the Lenders to any additional

unpaid principal amount of the Notes, or the number of Lenders, that shall be
required for the Lenders or any of them to take any action hereunder, (f)
release any material portion of any collateral held to secure the obligations of
the Borrower and



                                       31
   32

the Pledgor under any of this Agreement, the Cash Collateral Agreement and the
Notes or (g) amend this Section 8.01; and provided further that no amendment,
waiver or consent shall, unless in writing and signed by the Agent in addition

                  SECTION 8.03. No Waiver; Remedies. No failure on the part of
any Lender or the Agent to exercise, and no delay in exercising, any right
hereunder or under any Note shall operate as a waiver thereof; nor shall any

provided are cumulative and not exclusive of any remedies provided by law.

         preparation of a defense in connection therewith) (i) the Notes, this
         Agreement, any of the transactions contemplated herein or the actual or
         proposed use of the proceeds of the Advances except to the extent such
         claim, damage, loss, liability or expense is found in a final,
         non-appealable judgment by a court of competent jurisdiction to have
         resulted from such Indemnified Party's gross negligence or willful
         misconduct. In the case of an investigation, litigation or other
         proceeding to which the indemnity in this Section 8.04(b) applies, such
         indemnity shall be effective whether or not such investigation,
         litigation or proceeding is brought by the Borrower, its directors,
         equityholders or creditors or an Indemnified Party or any other Person,
         whether or not any Indemnified Party is otherwise a party thereto and
         whether or not the transactions contemplated hereby are consummated.
         The Borrower also agrees not to assert any claim against the 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.

                  (c) If any payment of principal of, or Conversion of, any
         Eurodollar Rate Advance is made by the Borrower 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 or Conversion pursuant to Section
         2.07, 2.08, 2.09, acceleration of the maturity of the Notes pursuant to
         Section 6.01 or for any other reason, the Borrower shall, upon demand
         by such Lender (with a copy of such demand to the Agent), pay to the
         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, 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.

                  (d) Without prejudice to the survival of any other agreement
         of the Borrower hereunder, the agreements and obligations of the
         Borrower contained in Sections 2.09, 2.11 and 8.04 shall survive the
         payment in full of principal, interest and all other amounts payable
         hereunder and under the Notes.

                  SECTION 8.05. Right of Set-off. Upon (i) the occurrence and
during the continuance of any Event of Default and (ii) the making of the
request or the granting of the consent



                                       33
   34

specified by Section 6.01 to authorize the Agent to declare the Notes due and
payable pursuant to the provisions of Section 6.01, each Lender 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 to or for the credit or the account of the Borrower
against any and all of the obligations of the Borrower 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
Borrower 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 under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) that such
Lender may have.

                  SECTION 8.06. 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 the Borrower and the Agent and when the Agent shall
have been notified by each Initial Lender that such Initial Lender has executed
it and thereafter shall be binding upon and inure to the benefit of the
Borrower, the Agent and each Lender and their respective successors and assigns,
except that the Borrower shall not have the right to assign its rights hereunder
or any interest herein without the prior written consent of the Lenders.

                  SECTION 8.07. Assignments and Participations. (a) Each Lender
may, subject to the consent of the Pledgor, assign to one or more Persons 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
Note or Notes held by it); provided, however, that (i) each such assignment
shall be of a constant, and not a varying, percentage of all rights and
obligations under this Agreement, (ii) except in the case of an assignment to a
Person that, immediately prior to such assignment, was a Lender or an assignment
of all of a Lender's rights and obligations under this Agreement, the amount of
the Commitment or, if no Commitment is remaining, the Advances, of the assigning
Lender being assigned pursuant to each such assignment (determined as of the
date of the Assignment and Acceptance with respect to such assignment) shall in
no event be less than $10,000,000 or an integral multiple of $5,000,000 in
excess thereof, (iii) each such assignment shall be to an Eligible Assignee, and
(iv) the parties to each such assignment shall execute and deliver to the Agent,
for its acceptance and recording in the Register, an Assignment and Acceptance,
together with any Note subject to such assignment and a processing and
recordation fee of $3,000, payable by the assignor. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, (x) 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 (y) the Lender assignor thereunder shall,
to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment and



                                       34
   35

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).

                  (b) 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, or the perfection or priority of any lien or security
         interest created or purported to be created under or in connection
         with, the Loan Documents 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 its obligations under any Loan Document or any
         other instrument or document furnished pursuant hereto; (iii) such
         assignee confirms that it has received a copy of the Loan Documents,
         together with copies of the financial statements referred to in Section
         4.01 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 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 Agent to take such action as agent on its behalf and
         to exercise such powers and discretion under this Agreement as are
         delegated to the Agent by the terms hereof, together with such powers
         and discretion as are reasonably incidental thereto; and (vii) such
         assignee agrees that it will perform in accordance with their terms all
         of the obligations that by the terms of this Agreement are required to
         be performed by it as a Lender.

                  (c) The Agent shall maintain at its address referred to in
         Section 8.02 a copy of each Assignment and Acceptance delivered to and
         accepted by it and a register for the recordation of the names and
         addresses of the Lenders and the Commitment of, and principal amount of
         the Advances owing to, each Lender from time to time (the "Register").
         The entries in the Register shall be conclusive and binding for all
         purposes, absent manifest error, and the Borrower, the Agent and the
         Lenders may treat each Person whose name is recorded in the Register as
         a Lender hereunder for all purposes of this Agreement. The Register
         shall be available for inspection by the Borrower or any Lender at any
         reasonable time and from time to time upon reasonable prior notice.

                  (d) Upon its receipt of an Assignment and Acceptance executed
         by an assigning Lender and an assignee representing that it is an
         Eligible Assignee, together with any Note



                                       35
   36

         or Notes subject to such assignment, the Agent shall, if such
         Assignment and Acceptance has been completed and is in substantially
         the form of Exhibit C hereto, (i) accept such Assignment and
         Acceptance, (ii) record the information contained therein in the
         Register and (iii) give prompt notice thereof to the Borrower. Within
         five Business Days after its receipt of such notice, the Borrower shall
         execute and deliver to the Agent in exchange for the surrendered Note a
         new Note to the order of such Eligible Assignee in an amount equal to
         the Commitment assumed by it pursuant to such Assignment and Acceptance
         and, if the assigning Lender has retained a Commitment hereunder, a new
         Note to the order of the assigning Lender in an amount equal to the
         Commitment 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 Acceptance and shall otherwise be in substantially
         the form of Exhibit A hereto.

                  (e) Each Lender may sell participations to one or more banks
         or other entities in consultation with the Pledgor 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 Note or 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, (iv) the Borrower, the Agent and the other Lenders
         shall continue to deal solely and directly with such Lender in
         connection with such Lender's rights and obligations under this
         Agreement and (v) no participant shall have the right to communicate
         directly with the Borrower with respect to any amendment or waiver of
         any provision of this Agreement or any Note, or any consent to any
         departure by the Borrower therefrom.

                  (f) Any Lender may, in connection with any assignment or
         participation or proposed assignment or participation pursuant to this
         Section 8.07, disclose to the assignee or participant or proposed
         assignee or participant, any information relating to the Borrower
         furnished to such Lender by or on behalf of the Borrower; provided
         that, prior to any such disclosure, the assignee or participant or
         proposed assignee or participant shall agree to preserve the
         confidentiality of any Confidential Information relating to the
         Borrower received by it from such Lender.

                  (g) Notwithstanding any other provision set forth in this
         Agreement, any Lender may at any time 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 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.

                  SECTION 8.08. Governing Law. This Agreement and the Notes
shall be governed by, and construed in accordance with, the laws of the State of
New York.

                  SECTION 8.10. 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.

                  SECTION 8.11. Jurisdiction, Etc. (a) Each of the parties
hereto hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement, the Notes or any other Loan Document, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that any party may otherwise have to bring any action or
proceeding relating to this Agreement, the Notes or any other Loan Document in
the courts of any jurisdiction. The Borrower hereby irrevocably appoints CT
Corporation System (the "Process Agent"), with an office on the date hereof at
1633 Broadway, New York, New York 10019, United States, as its agent to receive
on its behalf and its property service of copies of the summons and complaint
and any other process which may be served in any such action or proceeding in
any such New York State or federal court. Such service may be made by mailing or
delivering a copy of such process to the Borrower, in care of the Process Agent
at the Process Agent's above address, and the Borrower hereby irrevocably
authorizes and directs the Process Agent to accept such service on its behalf.
As an alternative method of service, the Borrower also irrevocably consents to
the service of any and all process in any such action or proceeding by the
mailing of copies of such process to the Borrower at its address specified in
Section 8.02. The Borrower agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law. In the case of any
legal action brought in Argentina, the Borrower hereby consents to the service
of any and all process in any such action or proceeding at its address specified
in Section 8.02. The Borrower irrevocably consents to the service of any and all
process in any such action or proceeding by sending copies of such process by
mail (by method requiring evidence of receipt) with a second copy to be sent to
the Borrower by courier at its address specified in Section 8.02.

                  (b) Each of the parties hereto irrevocably and unconditionally
         waives, to the fullest extent it may legally and effectively do so, any
         objection that it may now or hereafter



                                       37
   38

         have to the laying of venue of any suit, action or proceeding arising
         out of or relating to this Agreement, the Notes and any other Loan
         Document in any New York State or federal court. Each of the parties
         hereto hereby irrevocably waives, to the fullest extent permitted by
         law, the defense of an inconvenient forum to the maintenance of such
         action or proceeding in any such court.

                  (c) To the extent that the Borrower has or hereafter may
         acquire any immunity from jurisdiction of any court or from any legal
         process (whether through service of notice, attachment prior to
         judgment, attachment in aid of execution, execution or otherwise) with
         respect to itself or its property, the Borrower hereby irrevocably
         waives such immunity in respect of its obligations under this
         Agreement, the Notes and any other Loan Document and, without limiting
         the generality of the foregoing, agrees that the waivers set forth in
         this subsection (c) shall have the fullest scope permitted under the
         Foreign Sovereign Immunities Act of 1976 of the United States and are
         intended to be irrevocable for purposes of such Act.

U.S.$394,000,000                                            Dated: June 25, 1999


                  FOR VALUE RECEIVED, the undersigned, Azurix Buenos Aires S.A.,
an Argentine sociedad anonima (the "Borrower"), HEREBY PROMISES TO PAY to the
order of Westdeutsche Landesbank Girozentrale (the "Lender") for the account of
its Lending Office on the Maturity Date (each as defined in the Credit Agreement
referred to below) the principal sum of U.S.$394,000,000 (plus any amounts of
interest capitalized pursuant to Section 2.05(c) of the Credit Agreement dated
as of June 24, 1999 among the Borrower, the Initial Lender and other Lenders
from time to time party thereto, and the Agent for the Initial Lenders and such
other Lenders, (as amended or modified from time to time, the "Credit
Agreement"; the terms defined therein being used herein as therein defined)) or,
if less, the aggregate principal amount of the Advances (plus any amounts of
interest capitalized pursuant to Section 2.05(c)) made by the Lender to the
Borrower pursuant to the Credit Agreement outstanding on the Maturity Date.

                  The Borrower promises to pay interest on the unpaid principal
amount of each Advance from the date of such Advance until such principal amount
is paid in full, at such interest rates, and payable at such times, as are
specified in the Credit Agreement.

                  Both principal and interest are payable in lawful money of the
United States of America to Westdeutsche Landesbank Girozentrale, as Agent, at
The Chase Manhattan Bank, ABA 021- 000-021 for the account of the Lender,
Account No. 001-1-352275, Reference: Azurix Buenos Aires, in same day funds. The
Advance owing to the Lender by the Borrower pursuant to the Credit Agreement,
and all payments made on account of principal thereof, shall be recorded by the
Lender and, prior to any transfer hereof, endorsed on the grid attached hereto
which is part of this Promissory Note.

                  This Promissory Note is one of the Notes referred to in, and
is entitled to the benefits of, the Credit Agreement. The Credit Agreement,
among other things, (i) provides for the making of the Advance by the Lenders to
the Borrower from time to time in an aggregate amount not to exceed at any time
outstanding the U.S. dollar amount first above mentioned plus any amounts of
