     (b)  The subject annual report, semi-annual report, transition report

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K,
10-Q, N-SAR, or the transition report or portion thereof, could not be filed

MasTec, Inc. is unable to timely file its Annual Report on Form 10-K without
unreasonable effort and expense because MasTec's accountants have not
concluded their work in connection with the audited financial statements for
the year ended December 31, 2002.  As a result, MasTec cannot file its Annual
Report on Form 10-K until the financial statements are concluded.
