                             ENDESA'S RELEVANT FACT


New York,  October 21,  2005.-  Given the  confusion  created by Gas Natural SDG
S.A.'s  recent   statement   regarding   the  supposed   existence  of  required
authorizations  to  effect  the legal  separation  of its gas  distribution  and
transportation activities,  Endesa S.A. deems it necessary to make the following
observations for the general knowledge of the market:

1.   At the time it  announced  the tender offer for the  acquisition  of Endesa
     S.A.'s  shares,  Gas Natural SDG S.A. had not  undertaken the separation of
     its gas  distribution  and  transportation  activities,  because  it lacked
     -according  to  Endesa's  legal   advisors-  the  required   administrative
     approvals, as a result of which the National Energy Commission cannot grant
     Gas Natural SDG S.A. any approval to acquire share capital.

2.   According to the  information  notified by Gas Natural SDG to the CNMV,  by
     Relevant  Fact  number  61.180,   dated  October  3,  2005   (available  at
     www.cnmv.es),  its  Board  of  Directors  approved  the  separation  of its
     distribution  assets  project  through a transfer to Gas Natural SDG, S.A.,
     "transfer [that] will be immediately  completed through (...) share capital
     increases in Gas Natural  Distribucion  SDG". Said  announcement  expressly
     indicated that "from a legal,  operational and accounting perspective,  the
     separation  of  activities  will become  effective  as of October 1, 2005".
     Nonetheless,  Gas Natural did not point out that such transaction  required
     prior administrative approval.

3.   Gas Natural has repeated these statements in a Relevant Fact filed with the
     CNMV on October 19, 2005 (number 61.519, available at www.cnmv.es). In that
     announcement  the gas company  stated that "the  separation  of  activities
     became  effective as of October 1, 2005, in accordance  with the respective
     Public Deed [of share  capital  increase],  which,  in  addition,  has been
     registered with the commercial Registry on October 17, 2005".

4.   On October 4, Endesa  requested that the National Energy  Commission  (CNE)
     require  Gas  Natural to  request  to the  Commission  the  required  prior
     authorizations   for  the  creation  of  two  companies  (Gas  Natural  SDG
     Transporte  and Gas  Natural  SDG  Distribucion)  and  for  the  subsequent
     transfer of gas transportation and distribution  assets.  Likewise,  Endesa
     requested that the  Commission  suspend the  authorization  process for Gas
     Natural's tender offer for Endesa.

5.   On October 11, Gas Natural SDG  requested the CNE's  authorization  for the
     creation  of the  affiliates  and for the  transfer of  transportation  and
     distribution assets, if it deemed necessary.  On October 13 and October 18,
     the CNE decided,  with the dissenting vote of two commissioners,  that such
     authorizations should be processed simultaneously with Gas Natural's tender
     offer for Endesa, without the latter being suspended.


6.   Gas  Natural SDG  persists  today with the CNMV,  by  Relevant  Fact number
     61.584  (available at  www.cnmv.es)  in pretending to be in compliance with
     respect to the separation of activities that it has undertaken,  indicating
     that the  transaction  has been  reported  to the CNE and that  transfer of
     distribution  facilities  is not subject to Madrid  Autonomous  Community's
     approval, since "there are no rules regulating this issue".

7.   Nonetheless,  Gas Natural SDG has omitted to mention that the separation of
     activities requires "CNE's prior approval" and not an ex post notification,
     pursuant to article 63.7 of the LSH and the additional  provision 11,3.1,14
     of such Law. Therefore,  Gas Natural SDG's actions have been taken is in an
     irregular  manner  and  Endesa  reserves  such  rights as it may have under
     applicable law.

8.   In  addition,  Gas Natural  SDG  disregards  the fact that the  transfer of
     natural gas  distribution  facilities  also requires  prior  administrative
     approval by the applicable regulatory entity, as established in articles 86
     and 87 of the RD 1434/2002, of December 27. This rule is applicable both to
     Federal-regulated  natural gas distribution facilities and to those subject
     to the  Autonomous  Communities  that have not set their own  regulation on
     this issue. Therefore, the autonomous authorities regulate all distribution
     facilities  that affect a Community,  while the rest of the  facilities are
     subject to Federal regulation.

9.   Also untrue is Gas Natural  SDG's  statement in today's  Relevant Fact that
     articles 86 and 87 of the RD  1434/2002  are not legally  enforceable,  and
     even less that they contradict the Hydrocarbons  Sector Law (LSH). To start
     with,  every Royal Decree is presumed to be legal and  enforceable and also
     bears the State Council's  approval,  which has not raised any objection to
     the authorization  requirement for the transfer of distribution facilities.
     Secondly, these rules complete, in a perfectly consistent way, article 73.2
     LSH  which  only  refers to the  notification  of  assets  transfer  to the
     administrative  authority  that has issued the original  authorization.  It
     would be absurd to  assume,  and would  invite  all sorts of fraud,  that a
     company which  requires an  authorization  to install and operate a natural
     gas distribution  facility (article 73.2,  paragraph 1 LSH), could transfer
     it to a third  party by way of a simple  notification,  without  giving the
     competent  authority  the chance to assess  the  managerial,  economic  and
     technical  capabilities  of the  new  owner.  If the  original  owner  of a
     facility has to be authorized by the  Administration,  so do its subsequent
     owners.

10.  The transfer to Gas Natural  Distribucion of the  distribution  facilities,
     without having the corresponding  administrative  approvals,  suggests that
     Gas  Natural  SDG S.A.  may have  incurred  "very  serious"  administrative
     violations,   set  in  article   109.1.a)  LSH,  in  performing   regulated
     distribution  activities  (through the holding of ownership of distribution
     facilities)   without  having  the  required  approval.   As  very  serious
     violations,  it may carry a fine "from 100,000,001 to 500,000,000  pesetas"
     and may  give  rise to  termination  or  suspension  of the  administrative
     authorization  and the  "subsequent  temporary  prohibition  to operate the
     business  for a maximum  term of a year"  (article  113.1.a and 113.4 of RD
     1434/2002).  It should be noted that the administrative  authorizations are
     required to be obtained in advance,  and therefore  Gas  Natural's  actions
     have been taken is in an irregular  manner and Endesa  reserves such rights
     as it may have under applicable law.
