In compliance with article 228 of the Consolidated Text of the Spanish Securities Market Law, ABERTIS INFRAESTRUCTURAS, S.A. ("Abertis" or the "Company"), hereby notifies the Spanish National Securities Market Commission of the following

RELEVANT FACT

Grupo Concesionario del Oeste, S.A. ("GCO"), an Abertis Group company, together with the National Road Agency (Dirección Nacional de Vialidad), under the Transportation Ministry of Argentina, have signed a memorandum that formally initiates the process to extend its concession contract.

This extension involves the recognition of the pending rebalancing and an additional USD$250Mn investment plan to improve the current road network, which will be fully financed by future concession revenues, due to the extension of the contract, which currently ends in 2018, until the end of 2030.

This is the first step of a process that requires other legal and governmental approvals. The closing of the renegotiation will settle previous compensation claims between the concessionaire, its shareholders and the granting authority.

The company will keep the market informed of further developments as well as of more details of this process.
