Dear            ,

I am writing to update you on Endesa's response to the hostile tender offer
launched by Gas Natural (the "Offer") and inform you of what to expect from us
in the coming weeks.

As you will have seen, Endesa's Board of Directors has rejected the offer
unanimously based on the conviction that it is grossly inadequate and not in the
best interests of our shareholders. We strongly believe Endesa's stand-alone
Strategic Plan will deliver superior value to our shareholders compared to the
(highly uncertain) value implied by the Offer. Furthermore, Endesa's Board of
Directors is confident of achieving this superior value without the significant
risk entailed by the proposed transaction.

We are currently preparing a comprehensive response to the offer and will
contact you shortly to schedule a time to discuss it in person. In the meantime,
we ask for your continued support and confidence in the strong positive momentum
of the Endesa story.

Yours sincerely,






Rafael Miranda
CEO
