Statement by MasTec Regarding the Current Situation in Brazil

Business Wire, Sept 8, 1998

MIAMI--(BUSINESS WIRE)--Sept. 8, 1998--In the past several days, the Company has been asked for an assessment of the impact on MasTec (NYSE:MTZ) of the emerging markets situation that was triggered by the currency devaluation in Russia and has affected other markets, specifically Brazil.

We feel that our competitive position in Brazil is strong and foresee growth in the Brazilian telecom market over the next several years. This growth will be fueled by the recent privatization of Telebras. The privatization generated R$23 billion (U.S. $20 billion) for the Brazilian Treasury with the purchasers paying an average premium exceeding 60%, well above the 16% premium expected by the Brazilian government.

The companies that invested in Telebras, including well-capitalized companies such as Italia Telecom, Telefonica de Espana, Portugal Telecom and MCI, are required by the Brazilian government to meet minimum levels of fixed-line and wireless penetration, above and beyond current levels, within their respective geographic areas and within specific time deadlines. The first of these deadlines is year-end 1999.

According to ANATEL, the Brazilian Regulatory Agency responsible for overseeing the telecom industry in Brazil, the purchasers of the Telebras business units are required to increase line penetration by year-end 1999 as follows:

- 4,519,725 new fixed lines

- 5,999,900 new wireless subscribers

See the attached chart for further detail.

Based strictly on the privatization of Telebras, it is our belief that the primary industry segment that we service in Brazil - telecommunications - is solid and we expect the industry to carryout the capital expenditure programs as required by their purchase agreements.

MasTec owns 51% of MasTec Inepar. MasTec's invested cash in MasTec Inepar is $29.5 million or 3.6% of total assets. MasTec Inepar's daily operations are transacted in local currencies. MasTec's earnings from its Brazilian operations for the six months ended June 30, 1998 were $2 million. Revenues were $63.5 million, which represented 14.7 % of MasTec's total revenue for the same period. Although the Company has an optimistic outlook for its Brazilian prospects, it has not anticipated a significant increase in revenue or earnings contribution in 1998 from its share of the Brazilian operation.

Opening the Lines of Communication(R) worldwide, MasTec is one of the world's leading telecommunications and related infrastructure service providers, serving clients throughout the United States, Latin America and Spain. For more information, please visit our web site at www.mastec.com.
