Purchase Price,) that is, THREE POINT TWO THREE ONE ZERO EIGHT NINE SEVEN ZERO
FOUR EUROS ( 3.231089704) per share.  The Initial Purchase Price was agreed bearing in mind that the Closing
Date will be December 31, 2001, so that if, for any reason:  (i)the Closing Date falls any time after December
31, 2001, the Initial Purchase Price will increase with interest accrued on
said Initial Purchase Price from December 31, 2001 to the Closing Date
(hereinafter, Credit Interest) in accordance with the Formula contained in Appendix 4.1;
or, alternatively,  (ii)the Closing Date falls any time
before December 31, 2001, the Initial Purchase Price will be reduced by
interest calculated on the basis of said Initial Purchase Price for the period
between the Closing Date and December 31, 2001 (hereinafter, Interest on a
Debt) pursuant to the formula contained in Appendix 4.1.  The Initial Purchase Price, increased by the Credit Interest or reduced
by the Interest on a Debt, whichever is the case, will hereinafter be called
the Adjusted Initial Price.  Subsequent to the Closing, the Adjusted Initial Price will be changed
in accordance with the provisions of clause 4.4 (the Closing Adjustment.)  The Adjusted Initial Price plus or minus the
Closing Adjustment will hereinafter be called the Purchase Price.  Similarly, the Purchase Price may be subject
to new adjustments based on the provisions of clauses 9.1.(iv) and 9.2.(vii)
and 9.2.(ix).  The Initial Purchase Price, the Adjusted Initial Price, the Closing
Adjustment and any other adjustment to the Purchase Price derived from this
Agreement, will be distributed among the Sellers pro-rata based on their stake
in the Company.  4.2Advance  4.2.1Advance  In this act, the Buyer pays the Sellers, pro-rata based on their stake
in the Company, the amount of NINETY-THREE MILLION FIVE HUNDRED  10 
   THOUSAND EUROS ( 93,500,000), which represents 5 percent of the
Initial Purchase Price (hereinafter, the Advance.)  4.2.2Penalty  If the Buyer fails to appear under the terms set in clause 7 or is in
breach of its obligations as set forth in that clause, the Sellers will have
the right to keep the Advance, by way of penalty, without prejudice to its
right to file related legal action for breach of contract, and, in any event,
to demand compensation for legal damages.  4.3Form of Payment  The Advance will be paid by the Buyer to the Sellers through bank
transfer in liquid funds effected in favor of the Sellers, in the accounts the
Buyer has previously identified for that purpose, today, with value date today
also, for the amount in Euros net of expenses and charges as well as any tax
withheld, and this Agreement will constitute the most formal receipt.  The Adjusted Initial Price less the Advance will be paid by the Buyer
to the Sellers on the Closing Date, through bank transfer in liquid funds
effected by the Buyer in favor of the Sellers in the accounts that must be
identified for that purpose at least three Business Days in advance of the
Closing Date, for the amount in Euros net of expenses and charges as well as
any tax withheld.  The Closing Adjustment will be due and payable within five Business
Days of the Determination Date. The Party obligated to pay the Closing
Adjustment must make the payment through bank transfer in liquid funds and with
a value date of the fifth Business Day after the Determination Date, in the
current account(s) that must be identified by the Party that is the beneficiary
of the payment within two Business Days following the Determination Date, for
the amount in Euros net of expenses and charges as well as any tax withheld.  4.4Closing Adjustment  4.4.1Closing Adjustment  The Closing Adjustment will be equal to the difference between (i) the
amount of  225,121,100 with a negative sign and (ii) the Sum of the Working
Capital Fund and Net Liabilities based on the Closing Balance Sheet, under the
terms defined below.  For purposes of the provision in this clause, what is understood by Sum
of the Working Capital Fund and Net Liabilities based on the Closing Balance
Sheet is the difference between the arithmetical sum of the asset items and the
liability, as listed in Appendix 4.4.1, as taken from the Closing
Balance Sheet.  11 
   In the event that the Closing Adjustment is positive, it will be
payable by the Sellers to the Buyer. If it is negative, its absolute value will
be payable by the Buyer to the Sellers. In any event, the Parties expressly
agree that no payment whatsoever will be required in the event that the
absolute value of the Closing Adjustment, determined as provided in the
following clause, is less than  1,000,000.  4.4.2Procedure for determining the
Closing Adjustment  Within a period of thirty days as of the Closing Date, which may not be
extended, the Buyer will arrange for the Company to prepare and send to the
Sellers a Grupo Viesgo Consolidated Balance Sheet as of the Closing Date (the
Closing Balance Sheet.) It will include Viesgo Generación and Viesgo
Distribución on a fully consolidated basis, and Begasa and Barras Generación
consolidated proportionally with 54.93% consolidation. It must be drawn up in
accordance with accounting principles generally accepted in Spain, using the
approach established in the standards for adapting the General Chart of
Accounts to companies in the electric power industry, approved by Royal Decree
437/1998, of March 20.  Once the Closing Balance Sheet is received, the Sellers will ask an
independent auditor (hereinafter, the Auditor) to perform an audit of the
Closing Balance Sheet items listed in Appendix 4.4.1in accordance with
accounting principles generally accepted in Spain and send it to the Buyer and
the Sellers within a maximum period of 45 days as of the date when the Sellers
are sent the Closing Balance Sheet, the audit report on the Closing Balance
Sheet and a certification (the Auditors Certification) with their calculation
of the Sum of the Working Capital Fund and the Net Liabilities based on the
Closing Balance Sheet and the related Closing Adjustment, in accordance with
their auditing work.  For these purposes, the Buyer agrees to cooperate fully with the Auditor
and specifically agrees to provide the Auditor full access to all the documents
and information it may require, in its judgment, with no restrictions
whatsoever.  During a 15-day period as of the date on which the Auditor sends the
Parties its audit report and the Auditors Certification, the Buyer and its
accountants will have the opportunity to review the calculations effected. To
that end, the Sellers must request that the Auditor cooperate fully and in a
speedy, efficient way with the Buyer and its accountants, and that it allow
said Buyer or its appointed advisors to review its work papers.  12 
   If within the 5-day period following the conclusion of the 15-day
period to which the prior paragraph refers, the Buyer does not formally notify
the Sellers of any disagreement with the calculation of the Closing Adjustment
effected by the Auditor or formally notifies the Sellers that it accepts the
Closing Adjustment, the Closing Adjustment will be that established in the
Auditors Certification. In this case, the Closing Adjustment will be
understood to have been determined on the date on which the aforementioned
5-day period expires, or the date on which the Buyer formally notified the
Sellers of its acceptance of the Closing Adjustment established in the
Auditors Certification, in advance. In this case, it will be understood to
have been determined on the date of said notification (the Determination
Date.)  If the Buyer disagrees with the calculation of the Closing Adjustment,
within the 5-day period set forth in the prior paragraph, it must formally
notify the Sellers of its disagreement, stating the precise amount of the
Closing Adjustment according to its calculations (the Notification of
Disagreement.) Starting on the date of reception by the Sellers of the
Notification of Disagreement and during the 30 following days, the Parties will
try to reconcile their differences. In this regard, the Auditor and the Buyers
accountant will have access to the work documents of the other party with
respect to the materials that are the subject of the dispute. Similarly, they
will have the right to carry out additional audits. If the Parties reach a full
agreement in the aforementioned 30-day period, the Closing Adjustment will be
that agreed upon by the Parties, and the Determination Date will be the date on
which they reach that agreement.  If the Parties do not reach a full agreement on the Closing Adjustment
calculated by the Auditor within the aforementioned 30-day period, the
following procedure will be applicable:  (i)If the Parties reached a
partial agreement regarding the Closing Adjustment calculated by the Auditor
within the aforementioned 30-day period, that portion will be understood to be
payable for purposes of the provisions in the last paragraph of clause 4.3,
above, and it must be paid under the terms set forth in said paragraph, with
the understanding that the Determination Date is the date on which said 30-day
period terminates.  (ii)Regarding that portion of the
Closing Adjustment calculated by the Auditor on which an agreement is not
reached between the Parties (or the full amount, in the event of total lack of
agreement), the Parties will submit the matter to an accounting expert (the
Arbitrator) appointed by mutual agreement within a period of 5 days following
the termination of the aforementioned 30-day negotiation period.  If the Parties do not arrive at an agreement
on the selection of the Arbitrator during the aforementioned period, each Party
will propose and notify the other, on the following Business Day, of a short
list of experts chosen from among the following auditing firms with recognized
international prestige: Arthur Andersen, PriceWaterhouseCoopers, KPMG Peat
Marwick, Ernst&Young and Deloitte Touche, listed in order of preference,
assigned a value of 3 for the first choice, 2 for the second and 1 for the
third. Comparing the two short lists  13 
   provided, only those experts that appear on both notification lists
will be kept on the list, and they will thus proceed to add up the points
earned by each one.  As a result of the
foregoing, the expert among the above-mentioned four who receives the most
points will be appointed Arbitrator.  In
the event of a tie, the Arbitrator will be appointed by lot among those experts
with the most points that are tied.  As quickly as possible after his appointment, and, in any event, within
a maximum period of 30 days as of said appointment, the Arbitrator will issue a
report that will exclusively address the quantification of the matters that are
the subject of the dispute.  The
quantification of the matters that are the subject of the dispute by the
Arbitrator will be final, binding and definitive for the Parties and may not be
the subject of an appeal or any other form of recourse.  In this case, in the portion related to the
matters that are the subject of the dispute, the Closing Adjustment will be
that resulting from the Arbitrators report, and the Determination Date will be
the date on which said Arbitrator issues his report.  The fees and expenses of the Auditor will be for the account of the
Sellers, and those related to the Buyers accountant will be for the account of
the Buyer. The fees and expenses of the Arbitrator will be sustained half by
the Buyer, on the one hand, and half for the Sellers, on the other.  5.EVENTS BETWEEN AGREEMENT DATE AND
CLOSING DATE  5.1Between

and declared terminated by any Party if the Closing does not occur prior to the
expiration of a twelve-month period from the signing date hereof, or prior
thereto if any of the Conditions precedent cannot be fulfilled (the

obligated to refund the Advance to Purchaser within the ten Business Days
subsequent to the termination, plus interest on said amount from the date

Parties assume the following:  31 
   9.1Sellers  (i)The Sellers undertake to
accept such conditions as may be established by the competent defense
authorities, whether Spanish or Community, in the respective resolutions or
rulings that they may issue as set forth in Clause 3 above, as well as to

autonomous community, shall not be assumed as forming part of the current
clients of the Grupo Viesgo.  This restriction shall not apply
and shall remain invalid when the joint share on the peninsular market for
energy sold in the regulated and unregulated market corresponding to the Buyer
and its Affiliates (understood as those in which the Buyer holds a percentage
of capital greater than 10%) and the Company and its Subsidiaries is greater

allocated for such purposes on the outsourcing date, the Sellers jointly and
severally undertake to pay the Buyer, for the lower Purchase Price, an amount
equal to the resulting deficit. Such amount must be paid by bank transfer in
immediately available  32 
   funds and with value date no later
than the fifth Business Day after the date the Buyer confirms to the Sellers
the subscription or signing of the instruments, to the checking account to be
indicated by the Buyer to the Sellers for that purpose, on the same date as the
signing of the instruments is recorded, for its amount in Euros net of expenses
and fees, as well as any tax withholding.  9.2Buyer  (i)The Buyer undertakes to accept such conditions
as may be established by the competent defense authorities, whether Spanish or
European Community, in the respective resolutions or rulings that they may

obligations as the European Commission may impose pursuant to articles 6.1bis
or 8.2 of EEC Regulation 4064/89, to guarantee fulfillment of the acquired
commitments with a view to harmonizing the concentration with that of the
Common Market; all notwithstanding the provisions set forth in clause 3.4.  (ii)On or before the Closing Date,
the Buyer undertakes to sign an insurance policy or policies replacing those
currently in force, as set forth in Appendix
8.1.(Q).(i) of this Agreement, covering at least the same risks and
for the same amounts as the Endesa, S.A. general policy, which is described in
the aforementioned Appendix, currently covers for the Grupo Viesgo; such new
policy or policies must enter into force on the Closing Date and be signed with
an insurance company or companies of acknowledged reputation and solvency.  (iii)The Buyer is required to allow the

obligations) or their exercise of the right of defense to which they are
entitled pursuant to clause 11 below, or any other right acknowledged thereto
in this Agreement.  (iv)The Buyer assumes and is required
to fulfill and ensure that the Company and Subsidiaries fulfill the
social-labor regulations governing business successions, as contained in
Community law, article 44 of the Worker Statute and any other regulation,
accord or agreement that may apply thereto, both specifically and in general,
as provided for in the following paragraph.  33 
   For its part, the Company and Subsidiaries are completely subrogated
and bound to fulfill the conventional and contractual regulations and all labor
conditions applying to personnel affiliated with the companies, worksites and
facilities covered by this Agreement. Appendix
9.2.(iv).a includes the current collective agreements for such
personnel, including the first framework agreement of the Grupo Viesgo of July

and business reorganization agreements of the Endesa Group in 1999, and the
Grupo Viesgo agreement on specific matters of July 31, 2001.  Specifically and notwithstanding the provisions of the preceding
paragraphs, the Buyer expressly assumes and is required to fulfill and ensure
that the Company and/or Subsidiaries fulfill and/or are subrogated, as the case

commission for the Grupo Viesgo agreement on specific matters of July 31, 2001,
expressly undertaking to effectively adopt any measures as may be necessary to
provide for the relocation of affected workers in accordance with the terms set
forth in such agreement, before adopting extinctive labor relations measures
other than early retirement.  In

corresponding to the Employment Regulation Processes affecting the personnel of
the Company and Subsidiaries, by virtue of the provisions set forth in the

personnel. Appendix 9.2. (iv) c includes
the model labor agreement for members of the Grupo Viesgo Management Committee.  34 
   (v)The Buyer undertakes to ensure
that the Company and Viesgo Generation pay Endesa S.A. or any other companies in
the Endesa Group, on an annual basis, the funds contributed by such companies
to the various social security instruments intended to cover the current
pension commitments therein with respect to workers transferred to the Company
or Viesgo Generation and whose pension commitments are maintained at Endesa or
other companies of its Group during such time as its labor relations are
maintained with the Company or Viesgo Generation, all pursuant to Appendix 9.2.(v).  (vi)The Buyer undertakes not to hire
workers of the Endesa Group, of which the Sellers form part, for itself or for
any company in the Grupo Viesgo, for two years after the Closing Date, unless
such hiring occurs or results from a general offer of employment published in
the press or other mass communications medium.  (vii)The Buyer undertakes to:  (a)Accept for purposes of the
provisions of this clause and clause 9.1.(iv), and to continue applying after
the Closing Date:  the
assumptions and calculation criteria used for allocating internal funds to
cover the commitments assumed in the employment regulation processes affecting
the staff of the Company and Subsidiaries, and assumed thereby, to which the
warranty contained in clause 8.1.(P).(iii) refers.  the
assumptions and calculation criteria used for allocating internal funds to
cover the pension commitments affecting the staff of the Company and
Subsidiaries and assumed thereby, to which the warranty contained in clause
8.1.(P).(iv) refers.  (b)To continue performing, after the
Closing Date, the allocations corresponding to covering the commitments
indicated in section (a) above which are not outsourced as of that date, and
applying the assumptions and criteria indicated in such section (a) above.  (c)To ensure that the Company
and/or Subsidiaries sign such instruments as are submitted thereto by the
Sellers pursuant to clause 9.1.(iv) above.  In the event that the cost of the instruments submitted after the
Closing Date is less than the internal funds allocated for such items on the
outsourcing date, the Buyer undertakes to pay the Sellers (in  35 
   proportion to their share in the Company on the date of this
Agreement), for the higher Purchase Price, an amount equal to the resulting
excess. Such amount must be paid through a bank transfer, in immediately
available funds and with value date no later than the fifth Business Day after
the date the Sellers have presented the instruments to the Buyer, to such
checking account as the Sellers must indicate to the Buyer for that purpose, on
the same date as the instruments are presented, for their amount in Euros net
of expenses and fees as well as of all tax withholdings.  (viii)Regarding the coverage of retirement
contingencies or similar situations, invalidity and/or death, deriving both
from the corresponding collective agreements and the employment regulation
processes (ERES), the Buyer undertakes to ensure that Viesgo Distribución and
Viesgo Generación completely fulfill the agreement signed in this regard with
Endesa, S.A. and Endesa Generación, which is attached as Appendix 9.2.(viii), by virtue of which, in
order that the latter two companies may perform the corresponding reductions in
the Corporate Tax bases, the former two companies have committed to report,
regarding the aforementioned coverages, that during the immediately preceding
year they have met the conditions required by the general Corporate Tax
regulation to be considered as deductible.  This communication will be issued in accordance with the terms set
forth in the aforementioned agreement attached as Appendix 9.2.(viii), which the Buyer warrants in full
knowledge. To this end, the Buyer, along with Viesgo Generación and Viesgo
Distribución, jointly and severally guarantees fulfillment of this obligation
to communicate, and is jointly and severally bound with these companies to
repair the damage and losses provided for in the aforementioned agreement.  Notwithstanding the provisions set forth in the two preceding
paragraphs, the aforementioned agreement, which is attached as Appendix 9.2.(viii), provides that in the
event that an express ruling is obtained from the General Tax Office fully
ratifying the criteria set forth in statement 12 of the agreement attached as Appendix 9.2.(viii), such agreement shall
be rendered invalid, in which case it is expressly agreed that the commitment
assumed by the Buyer by virtue of this clause 9.2.(viii) shall be replaced by
the commitment provided for in clause 9.2.(ix) thereafter.  (ix)If an express ruling is obtained
from the General Tax Office fully ratifying the criteria set forth in statement
12 of the agreement attached as Appendix
9.2.(viii), i.e., that the future deductibility of the expenses
corresponds entirely to Viesgo Generación and Viesgo Distribución:  36 
   the Agreement attached as Appendix 9.2. (viii)
shall be invalidated except as provided for in the following paragraphs with
regard to obligations to report information; and  The
Buyer undertakes to pay to the Sellers each fiscal year (in proportion to their
share in the Company on the date of this Agreement), for the higher Purchase
Price, an amount equal to 35 percent of the downward adjustments (hereinafter,
the Downward Adjustments) to the Corporate Tax basis of Viesgo Distribución
and Viesgo Generación for the immediately preceding fiscal year, for the items
set forth in clause II of the agreement attached as Appendix 9.2.(viii), with such payment commitment to be
maintained until the total value of the Downward Adjustments exceeds the total
adjustments set forth in the aforementioned clause II. Notwithstanding the
above, if during any fiscal year the Corporate Tax basis of Viesgo Generación
or Viesgo Distribución is negative (i) before making the Downward Adjustment,
or (ii) as a result of making the Downward Adjustment, the obligation to pay
the amount corresponding to such Downward Adjustment, in case (i), or the
amount of such Downward Adjustment that exceeds the tax basis before it is
made, in case (ii), shall be deferred until the fiscal year when it is
effectively used by the corresponding corporation.  Such amounts must be paid to the Sellers, prorated for their ownership
interest in the Company, within five days after the 25 days following the six
months after the close of each fiscal year, in the corresponding amount, by
bank transfer in immediately available funds and with value date no later than
the fifth Business Day after the date ending the period legally established for
submitting the Corporate Tax return for Viesgo Distribución and Viesgo
Generación for such prior fiscal year, for the amount in Euros net of expenses
and fees as well as any tax withholdings. To this end, before the end of the
aforementioned legal period for submitting the Corporate Tax return, the
Sellers must provide notification of the checking accounts to which the
payments are to be made.  In order that the Sellers may verify proper settlement of the amounts
they are entitled to collect pursuant to this clause 9.2.(ix), the Buyer is
required to communicate to the Sellers the information set forth in clause II
of the agreement attached as Appendix
9.2.(viii), with the content and within the deadlines set forth
therein, expressly granting the Sellers the right to verify the information
contained in clause III of the aforementioned agreement.  37 
   10.INDEMNITY  10.1Sellers shall be jointly liable to Buyer for solely those damages that
presume a decrease in net worth of the Company and Subsidiaries, that are a
direct consequence of the lack of truthfulness in the statements and guarantees
made in Clause 8, noncompliance with the obligations established in
Clause 5.1 or claims by third parties against Viesgo Distribución under
the scope of Article 259 of the Corporations Law in relation to the division of
Electra de Viesgo I, S.A. in favor of Electra de Viesgo II, S.A. according to
the division document issued before the Notary of Burgos, Mr. José María de
Prada Díez on December 17, 1999, under No. 3,767 of his records, which led to
entry 12 on the corporate records of Electra de Viesgo I, S.A.; Buyer does not,
in any event, have to the right to indemnification for damages caused in
relation to events or circumstances revealed to Buyer or known thereto by
reason of documents or reports specifically cited in this Agreement.  10.2The indemnity obligation contemplated herein shall remain in effect:  (i)For a period of two years, as of the Closing
Date for damages that are a consequence of the lack of truthfulness of the
statements and guarantees made in Clause 8.1.(W);  (ii)During the period of the statute of limitations
plus sixty days for damages originating in the inaccuracy of statements
regarding tax and/or Social Security aspects;  (iii)For the legal period in relation to valid
ownership, encumbrances or other rights related to the Interests; and  (iv)For a period of one year as of the Closing Date
for the remainder.  10.3Buyer may not submit claims to Sellers under this Agreement whose amount
is less than100,000 and those so excluded shall not be calculated for purposes of
the deductible provided in Clause 10.4 below. For these purposes, all claims
deriving from one and the same cause are considered one single claim.  10.4The obligation to indemnify Buyer shall apply solely in the case of
claims against Sellers, the total amount whereof exceeds 0.5% of the Purchase
Price. Sellers shall therefore be liable only for amounts in excess thereof.  10.5The maximum indemnity to be paid by Sellers shall be limited to 15% of
the Purchase Price.  38 
   Nonetheless,
damages originating in the inaccuracy of statements related to the ownership of
the Interests and the absence of encumbrances thereon shall not be calculated
for purposes of the maximum indemnity limit and shall be indemnified in full by
Sellers, with the sole limit of the Purchase Price.  10.6Sellers Rights.  10.6.1The provisions of any other clause herein notwithstanding, there shall
be no obligation whatsoever to indemnify Sellers:  (a)With respect to those claims
that Buyer may have submitted after the periods cited in Paragraph 10.2 for
each of the cases mentioned therein have elapsed.  (b)With respect to third-party
claims that were not satisfied or that did not result in actual damage to net
worth for the Company or the Subsidiaries that was indemnifiable in accordance
with the provisions of this clause.  (c)With respect to claims for
which a specific reserve has been recorded, in terms of accounting, on the
Financial Statements for the item causing the claim, and up to the amount of
such reserve;  (d)With respect to damages that
would not have occurred if not for:  Actions or
omissions by Buyer, the Company or the Subsidiaries with the participation in
or knowledge of the adoption on the part of the Buyer, or Directors, managers
or employees designated by the latter,  The entry
into effect or adoption, after this day, of any legal provision, decree, order,
regulation or decision or administrative practice or amendment to the existing
ones,  The
amendment by Buyer of the accounting policies or practices of the Company or
Subsidiaries;  (e)With respect to damages that
may result from a price adjustment by reason of the provisions of any of the clauses
of the present Agreement.  10.6.2If, pending payment of an indemnity to Sellers in conformity herewith,
Buyer, the Company or Subsidiaries collects (whether by payment, discount,
credit, offset or otherwise) or may have a right to collect from a third party
a sum in relation to the damage that resulted in said claim, Buyer shall take
or permit the Company or Subsidiaries, as applicable, to  39 
   take
the precise measures to demand such collection, before demanding payment from
Sellers, and shall keep Sellers duly informed with regard to the rights and
collections made by it, and they shall be taken into consideration in order to
reduce the amount of the claim against Sellers.  10.7The Parties agree that any payment or indemnity paid by Sellers to Buyer
under the provisions hereof shall be considered a reduction in the Purchase
Price.  11.CLAIMS
AND PROCEDURES  11.1Third-Party
Claims against the Company or Subsidiaries  In
the case of third-party claims against the Company or Subsidiaries that may
result in an indemnification by Sellers under the scope of Clause 10 above,
Buyer shall notify Sellers of the filing of such claim as soon as it becomes
aware thereof, and in any event, within the first half of the period legally
established for response to said claim. Sellers shall have the right, but not
the obligation, to manage the proceedings that may result from such claims,
without prejudice to permitting Buyer and its consultants an active role in such
matters.  During the second half of the legal period for
response to the claim, Sellers shall notify Buyer of their decision regarding
management of the defense.  If the Sellers decide to direct the defense, the Buyer agrees (i) to
take the necessary measures so that the Company and/or the Subsidiaries will
grant sufficient powers to the Sellers or the persons designated by the
Sellers, (ii) to provide them with all information and documents necessary for
the defense, (iii) to cooperate in good faith with the Sellers in all matters
connected with the defense, (iv) that it will not take any action with respect
to the claim that might be in conflict with the defense assumed by the Sellers
or that might harm that defense and (v) to take the measures requested by the
Sellers in connection with the defense. All costs and expenses incurred by the
Buyer or the Grupo Viesgo, at the request of the Sellers, in the defense of
said claims shall be payable by the Sellers.  If the Sellers decide not to direct the defense of the claim, the
defense shall be the responsibility of the Buyer. The Buyer shall not accept
any responsibility for such claim, nor will it reach any settlement agreement
without the advance consent of the Sellers.  In the event of claims from third parties, the Sellers shall indemnify
the Buyer only if the Company or the subsidiaries have suffered damages as a
result of the final  40 
   and unappealable settlement, judgment or decision in connection with
such claims, and in the amount determined in such decisions.  The Buyer agrees to cooperate diligently and in good faith with the
Sellers to minimize any damage that might be caused by the claim from the third
party.  If the Buyer fails to perform its obligations of timely notice and
advance information in this clause 11.1, and in 11.2 below, the Sellers shall
be released from their obligation to indemnify under clause 10, only insofar as
such delay harms the right of defense of the Sellers and only in the amount of
the loss caused to the Sellers.  11.2 Claims
from buyer not entailing cause of claims from third parties  If the Buyer believes that the Company has suffered damage as a result
of an inaccurate representation of the Sellers, it shall communicate that
circumstance to the Sellers and the amount of such damage, within 30 days
following the date on which it learns of such circumstance. Such notice must
include a description of the nature, substance and amount of the claim and a
copy of the documentation connected with it, so that the Sellers will be able
to evaluate such claim properly. The Sellers shall have 30 days from the
receipt of such communication in which to reject or accept the claim that has
been made. During the next 30 days, the Sellers and the Buyer shall in good
faith negotiate a solution to the dispute that has arisen.  If the Sellers do not communicate their position on the claim within
the aforementioned time limit, it shall be understood that they are rejecting
it.  If there is no agreement between the parties about the existence or
nonexistence of the damage, or about its amount, the discrepancy shall be
resolved pursuant to the provisions of clause 15.  The Sellers shall bear a compensation obligation only for damage whose
existence or amount they have accepted, or damage that has been declared
through the procedure indicated in clause 15 and in the amount declared there,
in accordance with the provisions of this clause and in the previous clauses.  11.3 Common Provisions  11.3.1If
compensation is actually claimable by the Buyer from the Sellers pursuant to
this Agreement, the Sellers shall pay the amount of the damage  41 
   directly to the Buyer in the value that is necessary to put the Company
back into the asset position that it would be in if the inaccurate
representation and warranty that gave rise to the damage had been correct.  11.3.2Any
compensation that is payable by the Sellers under this Agreement shall be
reduced by any tax effect that the claim or loss that gave rise to it would
have actually had for the Company or the Subsidiaries.  12. ASSIGNMENT  The Parties may assign this
Agreement to any entity of the same group as the group to which the assigning
party belongs with the advance, written consent of the other Party, which may
not be unreasonably denied, and provided that, simultaneously, the assigning
party jointly and severally guarantees the performance of the obligations
derived from this Agreement by the assignee.  13. CONFIDENTIALITY  Both Parties agree to maintain
confidentiality and not to disclose to third parties the transaction that is
the subject of this Agreement, or its existence or contents, except when that
is necessary to meet the requirements of applicable laws and specifically the
rules and regulations of any Securities Exchange on which the shares of either
Party, or any company of the groups to which either Party belongs, are listed.  The Buyer agrees to maintain
the confidentiality of the information provided by the Sellers without
disclosing it to third parties, up until the Closing Date, and to obtain the
same commitment from its employees and advisors who participate in the Sale
Process.  However, if, for any reason,
the transfer of the Interests does not occur, the confidentiality obligation
shall be indefinite, and the Buyer must return to the Sellers all the documents
and information to which it has had access, including copies and, if
applicable, destruction, of the information to which it has had access on any
medium, in connection with this transaction.  In any event, the effectiveness
of the Confidentiality Agreement signed between the Buyer and Endesa, S.A. on
May 15, 2001 is confirmed on its own terms.  42
