Notice Information: This Notice was prepared with information provided by the Offeror (unless where stated expressly otherwise) in order to comply with CVM Instruction 361, providing the shareholders of the Company with elements deemed necessary to take an informed and independent decision regarding the acceptance of the Offer.

    2. Background: On July 1, 2016, as disclosed by CPFL, pursuant to a material fact on such date, one of its then-controlling shareholders, Camargo Corrêa S.A. ("CCSA"), received a proposal from State Grid for the acquisition of the totality of the shares of CPFL held directly or indirectly by CCSA that were bound to CPFL's shareholders' agreement dated as of March 22, 2002, as amended ("Shareholders' Agreement").

    3. In this regard, CCSA and State Grid entered into a binding Letter Agreement in respect of the potential acquisition, by one or more State Grid affiliates incorporated under the

      laws of Brazil, of two hundred and thirty-four million, eighty-six thousand, two hundred and four (234,086,204) shares issued by CPFL and owned by CCSA's subsidiary, ESC Energia SA ("ESC"), that were bound to the Shareholders' Agreement ("ESC Shares"), representing, approximately, 23% (twenty-three percent) of CPFL's capital stock.
