Present. -

Reference:  Relevant Information Communication

Dear Sirs,

Today, we became aware that the Congress of the Republic has approved Bill 1410/2016-CR, by which the Emergency Decree 003-2017 is modified and would include, among the effects of said regulation, companies that acted as partners, consortiums or associates with a participation of not less than 5% in the awarding of contracts in force with the Government, together with companies that have admitted the commission of crimes against the administration, or money laundering or equivalent crimes in tort of the Peruvian State.

Regarding this, and the legal analysis of the same, the company considers that in the case this becomes a Law, this regulation would be unconstitutional, attempting against the constitutional rights of presumption of innocence, due process, property, freedom to contract, equality before the law, freedom of work, among others.

If it becomes a Law, the regulation could negatively affect our company, generating the following effects:

· Put at risk approximately 32,000 direct jobs and more than 40,000 indirect jobs, and the families that depend on them.

· Affect almost 10,000 supplier companies of the Group with approximately 350,000 workers and their thousands of owners, many of them small companies.

· Cause a significant loss to the millions of Peruvian workers who are part of our company through their pension funds.

· Significantly affect the construction sector, which represents 6% of the national economy.

· Seriously affect institutionalism and legal security, as well as the international image of Peru as a country that respects the rule of law.

The company has invoked the government authorities to act responsibly avoiding the consummation of an act of abuse and arbitrariness such as would mean the enactment of this law. Likewise, the company will not hesitate to take the pertinent legal actions to defend its legitimate rights.

Sincerely,

__________________________
