Report of Independent Certified Public Accountants

The Plan Administrator
The MasTec, Inc. 401(k)
Retirement Savings Plan

We have audited the accompanying statements of net assets available for benefits of The MasTec, Inc. 401(k) Retirement Savings Plan as of December 31, 2002 and 2001, and the related statement of changes in net assets available for benefits for the year ended December 31, 2002. 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 in accordance with auditing standards generally accepted in the United States. Those standards 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. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2002, schedule of non-exempt transactions for the year then ended and schedule of reportable transactions for the year then ended are presented for purposes of additional analysis and are not a required part of the financial statements but are 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. These supplemental schedules are the responsibility of the Plan’s management. The supplemental schedules have been subjected to the auditing procedures applied in our audit of the financial statements and, in our opinion, are fairly stated in all material respects in relation to the financial statements taken as a whole.

Notes to Financial Statements

December 31, 2002

1.     Description of the Plan

The following description of The MasTec, Inc. 401(k) Retirement Savings Plan (the Plan) provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan covering all eligible employees of MasTec, Inc., (the Company) who have at least six months of service and are age twenty-one or older. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

The effective date of the Plan is December 1, 1984. The Plan was amended and restated in its entirety effective January 1, 2000. The amendments incorporated the requirements of the Uruguay Round Agreements Act, Uniformed Services Employment and Reemployment Rights Act of 1994, Small Business Job Protection Act of 1996, Taxpayer Relief Act of 1997 and the Internal Revenue Service Restructuring and Reform Act of 1998.

Effective January 1, 2002 the Plan was amended to reflect certain provisions of the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA).

Contributions

Each year, participants may elect to defer from 1% to 15% of pretax annual compensation received during the year, as defined by the Plan. Participants may contribute amounts representing distributions from other qualified defined contribution or defined benefit plans at the discretion of the Plan administrator. The Company makes discretionary matching contributions for participants. For 2002, the Company contributed 50% of the first 2% of gross salary that a participant contributes to the Plan.

Contributions from participants are recorded when payroll deductions are made. Company contributions accrue to the Plan at the payroll deduction dates.

Upon enrollment, a participant may direct employee contributions in 1% increments to any of the Plan’s fund options. Participants may change their investment options daily.

The Company matching contribution is in the form of Company common stock and is not subject to participant direction. The discretionary Company contributions accrue to the Plan when declared and are remitted prior to the date the Company files its federal income tax return for the corresponding fiscal year of the Company. During the year ended December 31, 2002, discretionary contributions of $813,661 were made to the Plan.

Participants’ Accounts

Each participant’s account is credited with the participant’s contributions and allocations of the Company’s contribution and Plan investment results. Allocations are based on participant earnings or account balances, as defined in the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account. If a participant separates from service before vesting, the portion of the account attributable to Company contributions is forfeited. Forfeited balances of participants’ nonvested accounts are used to reduce future Company contributions or pay administrative expenses of the Plan.


Vesting

Participants are immediately vested in their voluntary contributions plus actual earnings thereon. A Plan year during which an employee works for at least one thousand hours is counted as one year of vesting service. A participant becomes 100% vested in the remainder of his or her accounts upon the occurrence of any of the following events:

(a)     The participant dies while still in service as an employee;

(b)     The participant becomes totally and permanently disabled while still in service as an employee; or

(c)     The Plan is terminated by the Company.

Vesting in the Company contribution portion of their account plus actual earnings thereon is based on the years of continuous service. This is based upon a gradual vesting scale as follows:


Years of Service
Percentage
33%
66%
3 or more 100%

Participant Loans

A participant is only entitled to make a withdrawal from his or her account prior to separation from service if the participant qualifies for a hardship withdrawal or a participant loan. The Plan’s loan feature allows participants and beneficiaries to borrow up to a maximum equal to the lesser of $50,000 or 50% of their accrued vested benefit. The loans bear interest at the published prime rate in the Wall Street Journal plus 1%. Loan terms range from 1-5 years or may exceed 5 years for the purchase of a primary residence. Loans provide level amortization for repayments to be made not less frequently than on a quarterly basis.

Payments of Benefits

Upon 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 until a later retirement age upon election by the participant. For termination of service due to other reasons, a participant is entitled to receive only the vested percentage of his account balance.

2.     Summary of Significant Accounting Policies

Basis of Presentation

The financial statements of the Plan are prepared in conformity with accounting principles generally accepted in the United States. Certain reclassifications of prior year amounts have been made to conform to the 2002 presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.


Risks and Uncertainties

The Plan provides for various investment options in any combination of stocks, pooled separate accounts and guaranteed accounts. 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 benefits.

Investment Valuation

Plan investments are stated at fair value. The MasTec, Inc. Common Stock is valued at its quoted price on the last business day of the Plan year. The units of participation in pooled separate accounts are valued at fair value, which represents the redemption values established by Great-West Life & Annuity Insurance Company, the custodian, on the last business day of the Plan year.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Participant loans are valued at their outstanding balances, which approximate fair value.

Investment in Contracts Issued by Insurance Companies

The investment contracts are recorded at fair value at the end of each day, which represent contributions and reinvested income, less any withdrawals plus accrued interest.

Administrative Expenses

All administrative expenses of the Plan are chargeable to the Plan. The Company may, at its sole discretion, pay any such expenses, in whole or in part.

Benefit Payments

Benefits are recorded when paid.


3.     Investments

The Plan’s investments (including investments bought, sold and held during the year) appreciated (depreciated) in fair value for the year ended December 31, 2002 as follows:

Pooled Separate Accounts     $ (3,088,528 )
Common Stock     $ (2,335,814 )

      $ (5,424,342 )

4.     Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated September 5, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt. The plan administrator has indicated that it will take the necessary steps, if any, to maintain the Plan’s qualified status.

5.     Party-in-Interest Transactions

Certain Plan investments include shares of pooled separate accounts managed by the custodian. Therefore, such transactions are considered party-in- interest transactions. The Plan held investments in Company common stock with a fair value of approximately $2,051,000 and $2,896,000 as of December 31, 2002 and 2001, respectively.

6.     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 become 100% vested in their employer Contributions.
