TIM Participações S.A. ("Company") (BM&FBOVESPA: TIMP3; and NYSE: TSU), informs to the Market, its shareholders, and especially to its approximately 70 million users the following:

Referring to the notice to the Market dated August 07th 2012, in which we presented the Company's position in relation to the allegations that drop calls were being motivated by the Company's deliberated action.

Due to the negative impact on the Company's image and, above all, considering the questioning posed to the transparency in our relationship with our customers, the Company hired two independent institutions, with notorious reputation and worldwide level technical knowledge and vast performances in Brazil, Ericsson and PricewaterhouseCoopers.

Ericsson's highlight that: "According to the evaluations, scope of this work, Ericsson can safely state that there aren't any evidences raised on the Telephone Exchanges and Ericsson's Smart Grid Solutions that indicate purposive or intentional forms of promoting disconnections in TIM's PMS network". Furthermore, it adds that there aren't any evidences that such rate is in the order of 24%.

As for the drop call rate calculation referring to march 08th 2012, the results achieved by the methodology adopted by Ericsson was 2.09%, in line with the 2.04% results generated internally by TIM and which was confirmed by PricewaterhouseCoopers through a Agreed Upon Procedures Report - AUP.

The conclusions ratify the statement made by the Company in previous notice, denying any illicit practice or maneuver that could hurt the transparency in the relationship with its customers.

Both studies were concluded recently and presented to Anatel, as a contribution to the work that is being concluded by the Agency in the sense of clarifying this question.

The Company reaffirms its commitment with a quality service, transparency and, above all, honesty with our customers.

Rio de Janeiro, November 12th 2012.
