MATERIAL FACT

Magnesita Refratários S.A. ("Company"), pursuant to the terms of Law no. 6,404/76 and Rule no. 358/02 of Comissão de Valores Mobiliários ("CVM"), hereby informs its shareholders and the market in general:

As previously disclosed, on June 28, 2017, the European Commission approved the combination of RHI AG and Magnesita Refratários S.A. ("Magnesita"), subject to the divestment of (i) RHI AG's entire dolomite business (including production and sale) in the European Economic Area ("EEA"), which concerned the production sites in Marone (Italy) and Lugones (Spain); and (ii) Magnesita's production, sale, and related activities of magnesia- carbon bricks in the EEA, concentrated in Oberhausen (Germany) ("Oberhausen").

On September 8, 2017, Magnesita agreed to sell Oberhausen to INTOCAST Aktiengesellschaft Feuerfest-Produkte und Gießhilfsmittel for €20.3m. The disposal was subject to, among other conditions, buyer approval by the European Commission, which has now been obtained.

€19.0m is payable upon completion and €1.3m will be paid on the second anniversary of the closing date.

The proceeds from the sale will be used to further reduce the Company's net debt.

São Paulo, December 01, 2017.
