Report of Independent Certified Public Accountants To the Participants and Administrator of The MasTec, Inc. 401(k) Retirement Savings Plan: In our opinion, the accompanying statements of net assets available for benefits and the related statements of changes in net assets available for benefits present fairly, in all material respects, the net assets available for benefits of The MasTec, Inc. 401(k) Retirement Savings Plan (the "Plan") at December 31, 2000 and 1999, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Plan's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of Assets Held for Investment Purposes as of December 31, 2000 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ PricewaterhouseCoopers LLP Miami, Florida May 25, 2001 The MasTec, Inc. 401(k) Retirement Savings Plan Statements of Net Assets Available for Benefits December 31, 2000 and 1999 2000 1999 Assets: Investment at fair value $25,898,370 $26,320,770 Participant notes receivable 1,273,789 808,426 ----------- ----------- Total investments 27,172,159 27,129,196 ----------- ----------- Receivables: Participants' contributions 582,575 404,690 Employer's contributions 214,638 73,705 ----------- ----------- Total receivables 797,213 478,395 ----------- ----------- Net assets available for benefits $27,969,372 $27,607,591 =========== =========== The accompanying notes are an integral part of these financial statements.

The MasTec, Inc. 401(k) Retirement Savings Plan Notes to Financial Statements - --------------------------------------------------------------------- 1. Description of Plan The following description of The MasTec, Inc. (the "Company" or "MasTec") 401(k) Retirement Savings Plan (the "Plan") provides only general information. The Plan agreement contains a more complete description of the Plan's provisions. General The Plan is a defined contribution plan covering all employees of the Company who are age twenty-one or older and have six months of service. Eligible participants may enter the Plan on January 1 or July 1. It is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA") and is exempt from federal and state income taxes. The Plan is administered by the Employee Benefits Committee (Plan Administrator) of MasTec, Inc. Great-West Life & Annuity Insurance Company is the Recordkeeper of the Plan for all funds except for the MasTec Common Stock Fund which the Trustee is Wells Fargo Bank Minnesota, N.A. Plan assets are held by the Recordkeeper. Contributions Participants may contribute from 1% to 15% of their pre-tax annual compensation, subject to certain dollar amount limits, as defined in the plan agreement. The maximum contribution allowed was $10,500 and $10,000 during 2000 and 1999, respectively. Company contributions are 50% of each dollar up to 4% of the participant's gross salary. The Company match is exclusively in MasTec Common Stock. Whether and to what extent the Company will match employee contributions beyond 2000 will be at MasTec's discretion. During 1999, the defined contribution plans of certain companies acquired by MasTec, Inc. were converted to the Plan, and the related employees became participants of the Plan. The net assets of these plans were converted at a fair value of approximately $1,740,000 and invested in the Plan in accordance with the related employees' investment option elections. Such amounts are included as participants' contributions for 1999. In 2000, no plans of acquired companies were converted to the Plan. Participant Accounts Each participant's account is credited with the participant's contribution, the Company's contribution, rollovers into the Plan and an allocation of the participant accounts' earnings. Each participant's account is reduced by any withdrawals or distributions and an allocation of (a) his share of investment losses and depreciation in value of investments and (b) any administrative fees paid by the Plan. The benefit to which a participant is entitled is the participant's vested account balance. Transfers and Rollovers Participants may rollover balances held in other qualified retirement plans at the discretion of the Plan Administrator. Withdrawals Certain withdrawals from participant accounts are only allowed for financial hardship (in accordance with IRS regulations). Participant Notes Receivable Participants may borrow a maximum of the lesser of (1) $50,000 or (2) fifty percent (50%) of their individual vested account balance. Loan terms range from 1-5 years or up to 20 years for the purchase of a primary residence. The loans bear interest at the published prime rate in the Wall Street Journal plus 1%. Payment of Benefits On termination of service, due to death, disability, or retirement, a participant receives payment of the vested accrued benefit in a single lump sum or the payment can be deferred under certain circumstances to normal retirement age. For termination of service due to other reasons, a participant is entitled to receive only the vested percentage of his account balance. Vesting Participants are immediately vested in their contributions and rollovers and the earnings thereon. Participants are vested in Company contributions as follows: Years of Service Percentage - ---------------- ---------- 1 33% 2 66% 3 or more 100% Participants forfeit the portion of their account balance to the extent not vested. 2. Summary of Significant Accounting Policies The significant accounting policies followed by the Plan are as follows: Basis of Accounting The financial statements of the Plan are prepared in conformity with generally accepted accounting principles. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates. Risk and Uncertainties The plan provides for various investment options in any combination of stocks, bonds, fixed income securities, mutual funds, and other investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the statement of net assets available for plan benefits and the statement of changes in net assets available for plan benefits. Valuation of Investments and Income Recognition The Plan's investments are valued by the Recordkeeper (Note 1) and are stated at fair value using quoted market prices. Purchase and sales transactions are recorded on a trade date basis. Any gain or loss resulting from the sale of fund units is determined as the difference between the sales proceeds and the average cost of the units sold. Investment income is recorded on the accrual basis. Investment Income The Plan presents in the statement of changes in net assets available for benefits the net appreciation (depreciation) in the fair value of its investments which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Participant Withdrawals Withdrawals made by participants are recorded when paid. Administrative Costs All administrative expenses of the Plan, including, without limitation, the allocable portion of compensation of plan administrative staff and fees of employee benefits consultants, legal counsel, and auditors' fees are chargeable to the Plan. The Company may, at its sole discretion, pay any such expenses, in whole or in part. The Company assumed responsibility for administrative expenses for the years ended December 31, 2000 and 1999. 3. Investments The following investments represented five percent or more of the Plan's net assets at December 31, 2000: Maxim Money Market Portfolio $3,895,208 American Century Ultra Fund 1,845,961 Profile Series I - Aggressive Mix Portfolio 2,417,756 Profile Series II - Moderately Aggressive Mix Portfolio 1,671,764 MasTec Common Stock Fund 4,443,252 The following investments represented five percent or more of the Plan's net assets at December 31, 1999: Maxim Money Market Portfolio $4,723,125 American Century Ultra Fund 2,225,358 Fidelity Advisor Growth Opportunities Fund 1,691,331 Profile Series I - Aggressive Mix Portfolio 2,318,948 Profile Series II - Moderately Aggressive Mix Portfolio 1,417,497 MasTec Common Stock Fund 4,702,122 4. Plan Termination Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts. 5. Tax Status The Internal Revenue Service has determined and informed the Company by a letter dated June 17, 1997, that the Plan is designed in accordance with applicable sections of the IRC. The Plan has been amended since receiving the determination letter. However, the Plan Administrator and the Plan's legal counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC.
