COMPANHIA DE SANEAMENTO BÁSICO DO ESTADO DE SÃO PAULO – SABESP


PUBLICLY-HELD COMPANY
CORPORATE TAXPAYER ID (CNPJ): 43.776.517/0001 -80


NOTICE TO THE MARKET

Companhia  de  Saneamento  Básico  do  Estado  de  São  Paulo –  Sabesp,  hereby announces to its  shareholders  the  current  phase of  the  negotiations  between  the government of the state of São Paulo (“State”), its controlling shareholder and the São  Paulo  Municipal  Government  (“Municipality”),  to  enter  into a  Partnership Agreement to  establish  the  bases  for  sharing  the  responsibilities  for  water  supply and sewage services for the city of São Paulo. The negotiations also include Sabesp and the São Paulo State Sanitation and Energy Regulatory Agency (ARSESP), both as intervening and consenting parties.  

Considering that the definition of the power of concession for public basic sanitation services  (Articles  25  and  30  of  the  Federal  Constitution)  has  been  subject  of a lengthy legal dispute and the object of ongoing lawsuits in Brazil’s Supreme Court, this  partnerships  aims  to  guarantee  the  continuity  of  services  rendered  to  the population  of  São  Paulo  city,  integrate  local,  metropolitan  and  state  sanitation policies  and  grant  Sabesp  the  exclusive  right to  provide  the  services  for  the  next thirty (30) years, among others. 

On February 8, 2010, the Municipality held a Public Hearing to disclose the draft of said Partnership Agreement. 

At  this  moment  the  draft of  the  Partnership  Agreement is  available  till  March 5, 2010  at  the  Municipal  Housing  Department  Portal (www.prefeitura.sp.gov.br/cidade/secretarias/habitacao/), at the link “Planos”. 

São Paulo, February 19, 2010.
