MASTEC PROXY STATEMENT 2002 ANNUAL MEETING OF SHAREHOLDERS TO BE HELD MAY 23, 2002 The Board of Directors of MasTec, Inc. ("MasTec") is furnishing this Proxy Statement to solicit proxies on its behalf for use at the 2002 Annual Meeting of Shareholders of MasTec to be held at our corporate headquarters located at 3155 N.W. 77th Avenue, Miami, Florida 33122-1205, on Thursday, May 23, 2002, at 9:30 a.m. local time. At the Annual Meeting, our shareholders will be asked to vote on the following proposal, which is described in greater detail elsewhere in this Proxy Statement: - - The election of Jorge Mas, Jose Mas and Julia L. Johnson as Class I directors to serve until the 2005 Annual Meeting of Shareholders; and - - Such other business as may properly be brought before the Annual Meeting and at any adjournments of the Annual Meeting. The Board of Directors recommends that you vote FOR each of the nominees for Class I director set forth in this Proxy Statement. This Proxy Statement and accompanying proxy and other materials are first being mailed or transmitted electronically on or about April 29, 2002 to shareholders of record at the close of business on March 29, 2002. VOTING General The securities that can be voted at the Annual Meeting consist of our common stock, with each share entitling its owner to one vote on all matters brought before the Annual Meeting. Only shareholders of record at the close of business on March 29, 2002 are entitled to vote at the Annual Meeting. On the record date, 47,914,099 shares of common stock were outstanding and eligible to be voted at the Annual Meeting and MasTec had 3,262 record shareholders. Proxies If you are not present in person at the Annual Meeting, your shares can be voted only if represented by proxy or if you vote telephonically or online. The shares represented by your proxy will be voted in accordance with your instructions only if you properly complete, sign and return the accompanying proxy card to our Secretary prior to the Annual Meeting or vote your ballot online. Shareholders may be eligible to vote electronically through the Internet or by telephone. Please go to www.mastec.com under Investor Relations or follow the instructions accompanying your proxy card for more information on voting by telephone or online and registering to receive future proxy and other materials online. Shareholders not wishing to vote telephonically or electronically through the Internet or whose proxy card does not reference telephone or online voting information should complete and return the enclosed paper proxy card. Signing and returning the proxy card or submitting the proxy via telephone or online does not affect the right to vote in person at the Annual Meeting. If no choice is specified on the proxy card, the shares represented by the proxy will be voted for the election of all nominees for director and in the discretion of the holder of the proxy on all other matters that may properly come before the Annual Meeting. A proxy given pursuant to this solicitation may be revoked at any time prior to its exercise by written notice delivered to our Secretary, by executing and delivering to our Secretary a proxy with a later date, by attending the Annual Meeting and voting in person or by submitting a telephonic or electronic vote with a later date. With respect to telephonic or electronic votes, the last vote transmitted will be the vote counted. Attendance at the Annual Meeting will not, in itself, constitute revocation of a proxy. Under the rules of the New York and American Stock Exchanges, any beneficial owner of our common stock whose shares are held in street name by a member brokerage firm may revoke a proxy and vote their shares in person at the Annual Meeting only in accordance with applicable rules and procedures of the exchanges, as employed by the beneficial owner's brokerage firm. In addition to soliciting proxies through the mail, we may solicit proxies through our directors, officers and employees in person and by telephone or facsimile. Brokerage firms, nominees, custodians and fiduciaries also may be requested to forward proxy materials to the beneficial owners of shares held of record by them. All expenses incurred in connection with the solicitation of proxies will be borne by MasTec. Quorum and Vote Required The presence, in person or by proxy, of a majority of the shares entitled to vote is necessary to constitute a quorum at the Annual Meeting. If a quorum is present, directors will be elected by the affirmative vote of a plurality of the shares of common stock voting in person or represented by proxy at the Annual Meeting, which means that the three nominees receiving the highest number of votes will be elected to the Board of Directors. In voting for the proposal to elect nominees to the Board of Directors, shareholders may vote in favor of all the nominees or any individual nominee or withhold their votes as to all the nominees or any individual nominee. In accordance with Florida law, votes that are withheld will be counted in determining whether a quorum is present but will have no other effect on the election of directors. Under the rules that govern most domestic stock brokerage firms, member brokerage firms that hold shares in street name for beneficial owners may, to the extent that such beneficial owners do not furnish voting instructions with respect to any or all proposals submitted for shareholder action, vote in their discretion upon proposals that are considered "discretionary" proposals under the rules. Member brokerage firms that have received no instructions from their clients as to "non-discretionary" proposals do not have discretion to vote on these proposals. Although "broker non-votes" will be considered in determining whether a quorum exists at the Annual Meeting, "broker non-votes" will not be considered as votes cast in determining the outcome of any proposal. We believe that the proposal regarding the election of directors is discretionary. As of March 29, 2002 (the record date for the Annual Meeting), our directors and executive officers beneficially owned or controlled 23,405,414 shares of our common stock (670,256 of which are shares beneficially owned through unvested options), constituting approximately 47.1% of the outstanding common stock. We believe that these holders will vote their shares of common stock in favor of the nominees for Class I directors and, therefore, that the presence of a quorum and the election of the nominees is reasonably assured. Voting by Participants in the MasTec 401(k) Retirement Plan Separate proxy cards are being transmitted to all persons who have shares of our common stock allocated to their accounts as participants or beneficiaries under the MasTec, Inc. 401(k) Retirement Plan (the "Plan"). These proxy cards appoint Wells Fargo Bank, who acts as Trustee for the Plan, to vote the shares held for the accounts of the participants or their beneficiaries in the Plan in accordance with the instructions noted thereon. In the event no proxy card is received from a participant or beneficiary or a proxy card is received without instructions, or in the event shares are not yet allocated to any participant's account, the Trustee will vote the shares of stock of the participant and any unallocated shares "FOR" the nominees for director identified in this proxy statement. The Trustee does not know of any other business to be brought before the Annual Meeting but it is intended that, if any other matters properly come before the Annual Meeting, the Trustee as proxy will vote upon such matters according to its judgment. Any Plan participant or beneficiary who executes and delivers a proxy card to the Trustee may revoke it at any time prior to its use by executing and delivering to the Trustee a duly executed proxy card bearing a later date or by giving written notice to the Trustee at the following address: Wells Fargo Bank West, National Association, Attention: Penny Conyers - C7301-027, 1740 Broadway, Denver, Colorado 80274. Under the terms of the Plan, only the Trustee of the Plan can vote the shares allocated to the accounts of participants, even if such participants or their beneficiaries attend the Annual Meeting in person. ELECTION OF DIRECTORS The first matter that shareholders will vote upon at the Annual Meeting is the election of three directors, Jorge Mas, Jose Mas and Julia L. Johnson, as Class I directors for terms expiring at the annual meeting of shareholders in the year 2005. The Board of Directors currently is composed of eight directors elected in three classes, with three Class I, two Class II, and three Class III directors. Directors in each class hold office for three-year terms. The terms of the classes are staggered so that the term of only one class terminates each year. The terms of the current Class I directors expire at the Annual Meeting; if elected, the nominees for Class I directors will serve until the annual shareholders meeting in 2005. The terms of the Class II directors expire at the annual meeting of shareholders in 2003 and the terms of the Class III directors expire at the annual meeting of shareholders in 2004. Additional background information regarding the nominees for election is provided below. MasTec has no reason to believe that any of these nominees will refuse or be unable to serve as a director if elected; however, if any of the nominees is unable to serve, each proxy that does not direct otherwise will be voted for a substitute nominee designated by the Board of Directors. The Board of Directors recommends that you vote FOR each of the nominees named above. Unless otherwise indicated, the accompanying form of proxy will be voted FOR the election of each of the nominees for election as a Class I director named above.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors (the "Committee") is responsible for establishing and administering the policies for MasTec's compensation programs and for approving the compensation levels of the executives of MasTec, including its Chief Executive Officer. The Committee also reviews with the Chief Executive Officer guidelines for salaries and bonus awards applicable to MasTec's employees other than its executives. The Committee is composed of Arthur B. Laffer, who serves as Chairman, William N. Shiebler and Jose S. Sorzano, all of whom are non-employee directors of MasTec. Statement of Philosophy of Executive Compensation The executive compensation program of MasTec is designed to (i) provide base compensation reasonably comparable to that offered by other leading companies to their executives so as to attract and retain talented personnel, (ii) motivate executives to achieve the strategic goals set by MasTec by linking an executive's incentive compensation to the performance of MasTec and applicable business units, as well as to individual performance, and (iii) align the interests of MasTec's executives with the long-term interests of its shareholders through the award of stock options and other stock-related programs. To implement this philosophy, MasTec offers its executives compensation packages that include a mix of salary, incentive bonus awards, and stock options. In determining the level and form of executive compensation to be paid or awarded, the Committee relies primarily on MasTec's results of operations and, in the case of senior executives, an assessment of MasTec's overall performance in light of its strategic objectives. The primary factor the Committee considered in establishing 2001 compensation for senior executives was the net loss incurred by MasTec in 2001. Salary The base salary of executives is determined initially by analyzing and evaluating the responsibilities of the position and comparing the proposed base salary with that of executives in comparable positions in other companies. Adjustments are determined by objective factors such as MasTec's performance and the individual's contribution to that performance and subjective considerations such as additional responsibilities taken on by the executive. The Committee only increased the base salaries in 2001 of executive officers, including certain of the Named Executive Officers identified under the caption "Executive Compensation," who increased their job responsibilities with MasTec. Incentive Awards In addition to paying a base salary, MasTec awards incentive bonuses as a component of overall compensation. MasTec has established formal incentive compensation plans for our executives at both the corporate and operational levels that award incentive bonuses based primarily on MasTec's or an individual unit's performance as measured by earnings before interest and taxes ("EBIT"). Since bonuses are based on performance during a year and it takes time to gather and evaluate the necessary financial data to gauge performance, bonuses for performance in a year are not paid until the beginning of the next year. Awards are based on a multiple of base salary or a percentage of EBIT. A portion of the bonus may be awarded in stock and stock options. MasTec or the individual unit must meet certain minimum thresholds before any bonus is earned. For performance in 2001, the Committee awarded cash bonuses to certain of MasTec's executives under these plans. None of the Named Executive Officers received an incentive bonus award for 2001 performance. Chief Executive Officer Compensation Austin J. Shanfelter became our President and Chief Executive Officer in August 2001. The general philosophy described above for compensation of executive officers also applies to compensation for our Chief Executive Officer. Upon his election, Mr. Shanfelter's salary was increased to $500,000 per annum. In addition, Mr. Shanfelter was granted options to purchase 300,000 shares of our common stock to reflect his assumption of the role of President and Chief Executive Officer. No bonus compensation was paid for the calendar year 2001 to Mr. Shanfelter, or any other executive officer, based upon performance criteria established by incentive compensation plans for the calendar year. The Compensation Committee considered Mr. Shanfelter's assumption of additional responsibilities in establishing his base salary and awarding him options to acquire MasTec's common stock. Compensation Committee Interlocks and Insider Participation Mr. Laffer, who is a MasTec director and serves on our Compensation Committee, is a member of the board of directors of Neff Corp.

(2) All options were granted at an exercise price equal to fair market value based on the mean between the high and low sale prices of our common stock on the New York Stock Exchange on the date of grant. (3) Amounts represent hypothetical gains assuming exercise at the end of the option term and assuming rates of stock price appreciation of 5% and 10% compounded annually from the date the respective options were granted to their expiration date. The 5% and 10% assumed rates of appreciation are mandated by the rules of the Securities and Exchange Commission. These assumptions are not intended to forecast future appreciation of our stock price. The potential realizable value computation does not take into account federal or state income tax consequences of option exercises or sales of appreciated stock. The actual gains, if any, on the stock option exercises will depend on the future performance of our common stock, the optionee's continued employment through applicable vesting periods and the date on which the options are exercised and the underlying shares are sold. The closing price of our common stock on March 28, 2002, the last trading date prior to our record date, was $8.05 per share.

Employment and Other Agreements Effective January 1, 2001, MasTec entered into employment agreements with Austin J. Shanfelter, Carmen M. Sabater and Jose Sariego relating to their employment as Chief Operating Officer, Chief Financial Officer and General Counsel, respectively. Each of the agreements is for a term of two years unless earlier terminated, and provides that Mr. Shanfelter, Ms. Sabater and Mr. Sariego will be paid an annual salary of not less than $325,000, $270,000 and $240,000, respectively. Each agreement also provides for a bonus to be paid pursuant to an incentive compensation plan to be agreed upon, which plan may not be less favorable than the plan in effect for 2000. Additionally, if there is a change of control of MasTec during the employment term, the executive will be entitled to all of the unpaid portion of his or her salary for the remaining term of the agreement, to an immediate bonus payment and to immediate vesting of any previously unvested options. The agreements also contain non-competition and non- solicitation provisions during the term of the agreements. In August 2001, Mr. Shanfelter was elected President and Chief Executive Officer and his annual salary was increased from $325,000 to $500,000. We are in the process of negotiating a new employment agreement with Mr. Shanfelter to reflect his increased responsibilities. Ms. Sabater resigned as Executive Vice President and Chief Financial Officer in January 2002. In June 2001, MasTec agreed to pay up to $300,000 over a four year period of the premiums on policies of life insurance on Mr. Shanfelter and members of his family in exchange for a promissory note from Mr. Shanfelter in the full amount of the premiums to be paid plus interest together with an assignment of the policies as collateral for the promissory note. The full amount of the promissory note plus interest is payable solely from the cash surrender value or the proceeds of the policies, when paid, which are assigned to MasTec. The balance of the cash surrender value or proceeds from the policies, after repayment of the promissory note plus interest, will be remitted to the applicable insured's beneficiary. Effective August 7, 2001, MasTec entered into a severance agreement with Joel-Tomas Citron relating to his separation from MasTec. Under the agreement, MasTec is obligated to pay Mr. Citron $10,000,000 in equal installments, without interest, on September 3, 2001, January 2, 2002, April 1, 2002, July 1, 2002 and October 1, 2002. The final installment will be reduced by $750,000 to offset the amount due to MasTec under a non-interest bearing demand promissory note between MasTec and Mr. Citron. The severance agreement specifies that Mr. Citron will provide certain consulting services to MasTec upon MasTec's request until August 7, 2003. All of Mr. Citron's stock options to acquire MasTec common stock became fully vested and immediately exercisable under the severance agreement. Under the agreement, Mr. Citron agreed to certain restrictions on his ability to provide services to persons or entities that compete with MasTec or any of its affiliates, to solicit customers and employees of MasTec and to disclose MasTec's confidential information. Mr. Citron also agreed to aid MasTec in any legal proceedings or investigations and agreed to release MasTec from any claims relating to his employment with MasTec. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS As of December 31, 2001, Carmen M. Sabater was indebted to MasTec for $125,000 under a non-interest bearing demand promissory note. Ms. Sabater's obligation to repay her loan was forgiven by MasTec as part of her severance arrangement, which was effective January 1, 2002. As of December 31, 2001, Jose Mas, Vice Chairman of the Board and Executive Vice President, and Juan Carlos Mas, the brother of Jorge and Jose Mas, were indebted to MasTec for an aggregate of $72,673 and $116,533, respectively, representing advances made to them to pay their tax obligations resulting from the termination of the subchapter S corporation election of MasTec's predecessor company at the time of the merger of the predecessor company with Burnup & Sims Inc. in 1994. Interest on the advances has accrued at an annual rate of prime plus two percent. Subsequent to December 31, 2001, Jose and Juan Carlos Mas have paid this indebtedness in full. MasTec purchases, rents and leases equipment used in its business from a number of different vendors, on a non-exclusive basis, including Neff Corp., in which Jorge Mas, Jose Mas and Arthur B. Laffer serve as directors. Additionally, Jorge Mas, Juan Carlos Mas and Jose Mas have a significant ownership interest in Neff. During the year ended December 31, 2001, MasTec paid Neff approximately $2.3 million for equipment purchases, rentals and leases, which constituted approximately 3.5% of MasTec's total expense for equipment purchases, rentals and leases during the year. MasTec believes the amount paid to Neff is equivalent to the payments that would have been made between unrelated parties for similar transactions acting at arm's length. Julia L. Johnson, a nominee for director, entered into a one-year consulting agreement with MasTec through NetCommunications on June 1, 2000. The agreement specifies that Ms. Johnson will provide business development consulting to MasTec on a nonexclusive basis for a flat fee of $12,500 per month. Pursuant to the agreement, Ms. Johnson will identify new customers, identify additional business opportunities with existing customers, arrange meetings and presentations with new and existing customers, assist in the preparation of proposals, and provide guidance to develop additional business opportunities for MasTec. The agreement may be terminated by either party upon 90-days notice and contains customary non-compete, non-solicitation and confidential information provisions. The agreement expired in May 2001 but was continued on a month-to-month basis until April 2002, at which time the parties mutually agreed to terminate the agreement.

The Audit Committee members meet the independence and experience requirements established by the New York Stock Exchange. The Audit Committee adopted an Audit Committee Charter that was filed with the Proxy Statement for the 2000 Annual Meeting of Shareholders. In March 2002, the Board of Directors approved an amendment to the Audit Committee Charter that sets forth the current duties and obligations of the Audit Committee. A copy of the amended Audit Committee Charter is filed with this Proxy Statement. During 2001, the Audit Committee met with senior members of our financial management team, those responsible for the internal audit, our counsel and representatives of our independent auditors. The Audit Committee engaged PricewaterhouseCoopers LLP to audit the financial statements of MasTec for 2001. The Audit Committee also reviewed and approved the scope of the proposed audit for 2001, the procedures and schedules to be followed in connection with the audit and the audit fee proposed by PricewaterhouseCoopers. The Audit Committee also discussed with the independent auditors the matters required to be reviewed by Statement on Auditing Standards No. 61 (Communications with Audit Committees), as amended by Statement on Auditing Standards No. 90 (Audit Committee Communications), and reviewed the written disclosures and related correspondence from the independent auditors required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). The Audit Committee reviewed and discussed with the independent auditors their independence from MasTec. In connection with discussions regarding independence, the Audit Committee also considered with the independent auditors whether the provision of nonaudit services by independent auditors to MasTec is compatible with the auditors' independence. Our management has reviewed the audited financial statements contained in the Annual Report on Form 10-K with the Audit Committee, including a discussion of the accounting principles, the reasonableness of judgments and estimates, the clarity of disclosure in the financial statements and the conformity of the consolidated financial statements of MasTec with generally accepted accounting principles. In performing its functions, the Audit Committee acts in an oversight capacity. The Audit Committee relies on the work and assurances of our management, which has the primary responsibility for the financial statements and reports, and of the independent auditors, who, in their report, express an opinion on the conformity of our annual financial statements to generally accepted accounting principles. In reliance on these reviews and discussions, and the report of the independent auditors, the Audit Committee has recommended to the Board of Directors, and the Board of Directors has approved, that the audited financial statements be included in MasTec's Annual Report on Form 10-K for the year ended December 31, 2001, for filing with the Securities and Exchange Commission. Arthur B. Laffer, Chairman William N. Shiebler Jose S. Sorzano Audit Fees PricewaterhouseCoopers' fees for audit services related to the audit of our 2001 consolidated financial statements were $427,616. Financial Information Systems Design and Implementation Fees During 2001, MasTec paid no fees to PricewaterhouseCoopers in connection with financial information systems design and implementation. All Other Fees During 2001, MasTec paid PricewaterhouseCoopers $262,262 for all other services, principally tax structuring advice. Selection of Auditors The Audit Committee appointed PricewaterhouseCoopers to audit MasTec's financial statements for 2001. Based on MasTec's policy to review periodically the selection of independent auditors, the Audit Committee has selected Ernst & Young LLP as MasTec's independent auditors for 2002. MasTec expects that representatives of the independent auditors for 2001 and 2002 will be present at the Annual Meeting. The representatives will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions from shareholders. MISCELLANEOUS List of MasTec's Shareholders A list of MasTec's shareholders as of March 29, 2002, the record date for the Annual Meeting, will be available for inspection at our corporate headquarters located at 3155 N.W. 77th Avenue, Miami, Florida, during normal business hours during the 10-day period prior to the Annual Meeting. Shareholders' Proposals for 2003 Annual Meeting Under our bylaws, MasTec must receive any proposal of an eligible shareholder intended to be presented at the Annual Meeting of Shareholders of MasTec in 2003 on or before December 9, 2002, for the proposal to be eligible for inclusion in our Proxy Statement and Proxy related to that meeting. If a shareholder notifies MasTec after December 9, 2002, of an intent to present a proposal at MasTec's Annual Meeting of Shareholders in the year 2003 (and for any reason the proposal is voted upon at that Annual Meeting), MasTec's proxy holders will have the right to exercise discretionary voting authority with respect to the proposal, if presented at the meeting, without including information regarding the proposal in our proxy materials. Any notice regarding a shareholder proposal must include the information specified in Article I, Section 9 of our bylaws. A copy of these bylaw requirements will be provided upon written request to: MasTec Legal Department, 3155 N.W. 77th Avenue, Miami, Florida 33122-1205. Delivery of Proxy Materials - Householding Only one Annual Report for the year ended December 31, 2001 and Proxy Statement for the 2002 Annual Meeting is being delivered to multiple shareholders of record who share the same address and last name unless MasTec received contrary instructions from an affected shareholder. This practice is known as "householding" and helps reduce our expenses. Certain brokers and banks that hold MasTec stock for their customers may also household. Each shareholder who resides at a householded address will be mailed a separate proxy card. MasTec will promptly deliver a separate paper copy of the Annual Report and Proxy Statement to a shareholder at a shared address to which a single copy of these documents was delivered upon receiving an oral or written request from the shareholder. Any such shareholder who wishes to receive a separate paper copy of our Annual Report and Proxy Statement for the 2002 Annual Meeting or future meetings should contact MasTec Investor Relations by telephone at 1-305-599-1800 or by mail to: MasTec Investor Relations, 3155 N.W. 77th Avenue, Miami, Florida 33122-1205. Any shareholders of record sharing an address who now receive multiple copies of our Annual Report and Proxy Statement and who wish to receive only one copy of these materials per household in the future should also contact MasTec Investor Relations by telephone or mail as instructed above. Any shareholders sharing an address whose shares of our stock are held by a broker or bank, who now receive multiple copies of our Annual Report and Proxy Statement and who wish to receive only one copy of these materials per household, should contact the broker or bank to request that only one set of these materials be delivered in the future. Other Matters that May Come Before the Annual Meeting The Board of Directors does not intend to present and knows of no others who intend to present at the Annual Meeting any matter or business other than that set forth in the accompanying Notice of Annual Meeting of Shareholders. If other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the accompanying form of proxy to vote any proxies on such matters in accordance with their judgment. MasTec's Annual Report on Form 10-K for the year ended December 31, 2001 is being mailed or transmitted with this Proxy Statement to shareholders of record as of March 29, 2002. The Form 10-K does not form any part of the material for the solicitation of proxies. /s/ Jose Sariego - ------------------------- Jose Sariego, Secretary Miami, Florida April 25, 2002 EXHIBIT A
