REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Trustees of the
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, 1996 and
1995, and the related statements of changes in net assets available for benefits
for the years ended December 31, 1996 and 1995.  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  generally   accepted  auditing
standards.  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 as of
December 31, 1996 and 1995, and the changes in net assets available for benefits
for the years ended  December 31, 1996 and 1995,  in conformity  with  generally
accepted accounting principles.

Our audits  were  performed  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of Assets Held
for Investment Purposes of The MasTec, Inc. 401(k) Retirement Savings Plan as of
December 31, 1996,  and  Reportable  Transactions  for the year then ended,  are
presented for the purpose of additional  analysis and are not a required part of
the basic 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. The Fund Information in the
statement of net assets  available  for benefits and the statement of changes in
net assets  available  for  benefits is  presented  for  purposes of  additional
analysis  rather than to present the net assets  available for plan benefits and
changes in net assets available for plan benefits of each fund. The supplemental
schedules and Fund  Information  have been subjected to the auditing  procedures
applied in our 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.

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 one year 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 Administrators). Effective January 1, 1996, the Board of Directors appointed Great-West Life & Annuity Insurance Company as Trustee and Recordkeeper of the Plan for all funds except for the MasTec Common Stock Fund which the Trustee is Norwest Bank, Minnesota, N.A. Plan assets are held by the Trustee. 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 during 1996 and 1995 was $9,500 and $9,240, respectively. The Company may, at its sole discretion, contribute to the Plan. During 1996 and 1995, no contributions were made. Effective January 1, 1997, the Company will contribute 25% of each dollar up to 4% of the participant's gross salary. The Company match will be exclusively in MasTec Common Stock, and will be subject to certain restrictions. Whether and to what extent the Company will match employee contributions beyond 1997 will be at MasTec's discretion. Participant Accounts Each participant's account is credited with the participant's contribution, the Company's discretionary contribution, if any, any rollovers into the Plan (permitted at the discretion of the plan administrator) and an allocation of the Plan's 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) administrative fees paid by the Plan if not paid by the Company. The benefit to which a participant is entitled is the participant's vested account balance. THE MASTEC, INC. 401(K) RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS, Continued 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. 1. Description of the Plan, Continued: Vesting Participants are immediately vested in their contributions and rollovers and the earnings thereon. Participants are vested in Company contributions, if any, to the extent reflected below: Years of Service Percentage --------------- 1 0% 2 20% 3 40% 4 60% 5 80% 6 or more 100% Participants forfeit the portion of their account balance to the extent not vested. There were no amounts forfeited as of December 31, 1996 and 1995. 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 revenues and expenses 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. 2. Summary of Significant Accounting Policies, Continued: Valuation of Investments and Income Recognition The Plan's investments are valued by the trustees (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, 1996 and 1995. 3. Investment Contract With Insurance Company: The Plan had during 1995 a Group Annuity Contract with the Hartford Life Insurance Company ("ITT Hartford"). ITT Hartford maintained the contributions in an Immediate Participation Fund. The contract was included in the 1995 financial statements at contract value, as reported to the Plan by ITT Hartford. Such contract was terminated during 1996. 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. Reconciliation of Financial Statements to Form 5500: The following is a reconciliation of net assets available for benefits per the financial statements to the Form 5500: 1996 1995
