Accordingly, shareholders (or their legal representatives) attending the Annual Meeting should bring some form of identification to the meeting evidencing shareholder status as of the record date and, in the case of a person attending the meeting on behalf of a shareholder, the representative's right to represent the shareholder at the meeting. All shareholders are cordially invited to attend the Annual Meeting in person. However, to ensure that your stock is represented at the meeting in case you are not personally present, you are requested to mark, sign, date and return the enclosed proxy card as promptly as possible in the envelope provided. You may not vote your shares of stock at the Annual Meeting unless you are present in person or represented by proxy. Shareholders attending the Annual Meeting may vote in person even if they have previously returned a proxy card. By order of the Board of Directors /s/Nancy J. Damon Nancy J. Damon Corporate Secretary Miami, Florida April 5, 2000

PROXY STATEMENT _______________ ANNUAL MEETING OF SHAREHOLDERS MAY 17, 2000 _______________ GENERAL The Board of Directors of MasTec, Inc. ("MasTec") is furnishing this Proxy Statement to solicit proxies for use at the 2000 Annual Meeting of Shareholders of MasTec, to be held at our corporate headquarters located at 3155 N.W. 77th Avenue, Miami, Florida, on Wednesday, May 17, 2000, at 9:30 a.m., local time. At the Annual Meeting, our shareholders will be asked to vote on the following matters, each of which is described in greater detail elsewhere in this Proxy Statement: * The election of two Class II directors for terms expiring in 2003; * An increase in the number of shares of Common Stock reserved for issuance under MasTec's 1994 Stock Incentive Plan from 2,500,000 to 3,500,000 and certain related amendments to the plan; and * Such other business as may properly be brought before the Annual Meeting. The Board of Directors recommends that you vote FOR each of the nominees for Class II director set forth in this Proxy Statement and FOR the increase in the shares reserved for issuance under the 1994 Stock Incentive Plan. This Proxy Statement and accompanying proxy and other materials are first being mailed on or about April 5, 2000 to shareholders of record on March 21, 2000. Only shareholders of record at the close of business on March 21, 2000 are entitled to vote at the Annual Meeting. If you are not present in person at the Annual Meeting, your shares can be voted only if represented by proxy. 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 Corporate Secretary prior to the Annual Meeting. If no choice is specified, the shares represented by the proxy will be voted for the election of all nominees for director, for the increase in the shares reserved for issuance under the 1994 Stock Incentive Plan, 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 Corporate Secretary, by executing and delivering to our Corporate Secretary a proxy with a later date, or by attending the Annual Meeting and voting in person. Attendance at the Annual Meeting will not, in itself, constitute revocation of a proxy.

MasTec's only class of voting securities is its Common Stock. At March 21, 2000, there were 31,003,830 shares of our Common Stock outstanding, which is the only class of MasTec's capital stock outstanding. As of March 21, 2000 MasTec had 4,569 record shareholders, which does not include shareholders whose shares are held of record by a brokerage firm or otherwise in "street name." Each share of our Common Stock entitles its holder to one vote on all matters properly brought before the Annual Meeting. 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 are elected by a plurality of the votes of the shares voting in person or represented by proxy at the Annual Meeting, which means that the nominees receiving the highest number of votes will be elected to the Board of Directors. If a quorum is present, in order for the increase in the shares reserved for issuance under the 1994 Stock Incentive Plan to be approved, the number of votes cast in favor of the proposal must be greater than the number of votes cast against the proposal. Shares that are entitled to vote but that are not voted at the direction of the beneficial owner ("abstentions"), shares represented by proxies or ballots that are marked "withhold authority", and votes withheld by brokers in the absence of instruction from beneficial holders ("broker nonvotes") will be counted for the purpose of determining whether there is a quorum for the transaction of business at the Annual Meeting. In determining whether a matter requiring approval of a majority of the shares voting at the Annual Meeting has been approved or whether a nominee for director has received a plurality of the shares, abstentions, withheld votes and broker nonvotes will be disregarded and will have no effect on the outcome of the vote. ELECTION OF DIRECTORS The first matter that shareholders will be asked to vote upon at the Annual Meeting is the election of two Class II directors for terms expiring at the annual meeting of shareholders in the year 2003. The Board of Directors currently is comprised of eight directors elected in three classes, with two Class I, three Class II, and two 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 one class terminates each year. The terms of the current Class II directors expire at the Annual Meeting; if elected, the nominees for Class II directors will serve until the annual shareholders meeting in 2003. The terms of the Class III directors expire at the annual shareholders meeting in 2001 and the terms of the Class I directors expire at the annual meeting of shareholders in 2002. One of the current Class II directors, Eliot Abbott, has informed MasTec that he does not wish to stand for reelection, and the Board of Directors, as permitted by our bylaws, has resolved that the Board of Directors will be comprised of seven directors (subject to further adjustment by the actions of our Board of Directors or shareholders) following the expiration of the terms of our current Class II directors at the Annual Meeting. The reduction in the size of the Board of Directors will be effected by electing only two Class II directors at the Annual Meeting.

The following individuals have been nominated by the Nominating Committee of the Board of Directors for election as the Class II directors to be elected at the Annual Meeting: * Olaf Olafsson * William N. Shiebler Additional background information regarding each of these nominees is provided below. MasTec has no reason to believe that either of these nominees will refuse or be unable to serve as a director if elected; however, if either 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 election of directors requires the affirmative vote of a plurality of the shares of Common Stock voting in person or by proxy at the Annual Meeting. 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 II director named above.

There are four standing committees of the Board of Directors: the Executive Committee, the Audit Committee, the Compensation Committee, and the Nominating Committee. The Executive Committee is composed of Jorge Mas, who serves as Chairman, Joel-Tomas Citron and Arthur Laffer. The principal function of the Executive Committee is to act for the Board of Directors when action is required between full Board meetings. During 1999, the Executive Committee met or acted by unanimous written consent nine times. The Audit Committee is composed of Arthur Laffer, who serves as Chairman, and Eliot Abbott, Olaf Olafsson, and William N. Shiebler.

During 1999, the Audit Committee met on six occasions. The Compensation Committee is composed of Arthur Laffer, who serves as Chairman, Olaf Olafsson, Jose Sorzano and William Shiebler. The Compensation Committee is charged with determining compensation packages for the Chief Executive Officer and the Senior Vice Presidents of MasTec, establishing salaries, bonuses and other compensation for MasTec's other executive and operating officers, administering MasTec's stock option, stock purchase and incentive compensation plans and recommending to the Board of Directors changes to the plans. During 1999, the Compensation Committee met or acted by unanimous consent on 12 occasions. The Nominating Committee is composed of Eliott Abbott, who serves as Chairman, and Jorge Mas and Joseph Kennedy, II. The Nominating Committee recommends to the Board of Directors candidates for election to the Board of Directors. The Committee considers candidates recommended by the shareholders pursuant to written applications submitted to our Corporate Secretary. Shareholder proposals for nominees should include biographical and other information regarding the proposed nominee sufficient to comply with applicable disclosure rules and a statement from the shareholder as to the qualifications and willingness of the candidate to serve on our Board of Directors. During 1999, the Nominating Committee met on four occasions. Compensation of Directors Under MasTec's Non-Employee Directors' Stock Option Plan, our non-employee directors are eligible to receive annually options to purchase shares of Common Stock. The amount and exercise price of the options granted under this plan are set by the Compensation Committee. Options issued under the plan are in lieu of all other compensation to directors for their services as directors. MasTec does not separately compensate its employee directors for their services as directors. Directors are reimbursed for their reasonable expenses in attending Board and committee meetings.

Employment Agreements Effective January 1, 2000, MasTec entered into a new employment agreement with Mr. Citron relating to his employment as the Vice Chairman of the Board of Directors, President and Chief Executive Officer. The new agreement is for a term of two years unless earlier terminated, and provides that Mr. Citron will be paid an annual salary of not less than $500,000 in 2000 and $600,000 in 2001. The new agreement also provides for a bonus to be paid to Mr. Citron if MasTec achieves certain budgeted levels of earnings before interest and taxes ("EBIT"), and will be based on a percentage of EBIT, which is consistent with our service line presidents' bonus plan. Additionally, if there is a change of control of MasTec during Mr. Citron's employment term, Mr. Citron will be entitled to all of the unpaid portion of his salary for the full term of this agreement, any bonus that he would have earned for the year in which the change of control occurs, and to certain payments based on stock price levels as well as immediate vesting of any previously unvested options. This agreement also contains non-competition and non-solicitation provisions.

APPROVAL OF AN INCREASE IN THE NUMBER OF SHARES RESERVED FOR ISSUANCE UNDER MASTEC'S 1994 STOCK INCENTIVE PLAN MasTec has adopted and our shareholders have previously approved the 1994 Stock Incentive Plan (the "Stock Incentive Plan"). The Stock Incentive Plan currently provides for the issuance of an aggregate of 2,500,000 shares of Common Stock, including restricted stock and stock issued upon the exercise of stock options. As of March 21, 2000, only 67,644 shares of Common Stock remained available for issuance under the plan. On February 7, 2000, the Board of Directors approved an amendment to the Stock Incentive Plan to increase the maximum number of shares of Common Stock that may be issued under the plan by 1,000,000 and to make certain other related amendments to the plan. Shareholders are being asked to consider and approve the amendment to the Stock Incentive Plan. Approval of the amendment requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or by proxy at the Annual Meeting. The amendment will be approved if the votes cast in favor of the amendment are greater than the votes cast against the amendment. The Board of Directors believes that awards under the Stock Incentive Plan serve to attract, retain and motivate key employees, to enhance their incentive to perform at the highest level and to contribute significantly to our success by tying the compensation of these employees to MasTec's performance and aligning their interests with the long-term interest of MasTec and its shareholders. The Board of Directors believes that the proposed amendment furthers these objectives by ensuring that a sufficient number of shares of Common Stock are available to be granted or issued under the Stock Incentive Plan. The Board unanimously recommends a vote FOR approval of the amendment to increase the number of shares of Common Stock that may be issued under the Stock Incentive Plan. Unless otherwise indicated, the accompanying form of proxy will be voted FOR the approval of the amendment. Summary of the Stock Incentive Plan The following is a summary of the significant features of the Stock Incentive Plan, as it currently exists and as proposed to be amended. A copy of the plan, as proposed to be amended, is attached to this Proxy Statement as Exhibit "B." Number of Shares Covered by the Plan Subject to adjustment as noted below, the total number of shares that may be optioned or awarded under the Stock Incentive Plan currently is 2,500,000 shares of Common Stock, of which 500,000 shares may be awarded as restricted stock. This amount will increase to 3,500,000 shares, of which 1,000,000 shares may be awarded as restricted stock, if the proposed amendment to the Stock Incentive Plan is approved by shareholders. No employee may receive, over the term of the Stock Incentive Plan, awards in the form of options to purchase more than 500,000 shares of Common Stock, which number would be increased to 1,000,000 if the amendment is approved. Any shares subject to an option under the Stock Incentive Plan that for any reason expires, is relinquished or is terminated unexercised and any restricted stock that is forfeited may again be optioned or awarded under the Stock Incentive Plan, except that forfeited shares are not available for further awards if the employee has realized any benefits of ownership from the forfeited shares.

Eligible Participants in the Plan Key employees, including officers, of MasTec and its subsidiaries, are eligible to participate in the Stock Incentive Plan. The Compensation Committee of the Board of Directors (the "Committee") administers the Stock Incentive Plan and determines the recipients of options and awards, their terms and conditions within the parameters of the Stock Incentive Plan and the number of shares covered by each option or award. The Committee may approve rules and regulations to carry out the Stock Incentive Plan and its decision with regard to any question arising under the Stock Incentive Plan is final and conclusive. The Committee members are not eligible to participate in the Stock Incentive Plan. No award or option may be granted under the Stock Incentive Plan after January 2004, but awards or options granted before that date may extend beyond that date. The Board of Directors may amend, alter or discontinue the Stock Incentive Plan, but no amendment, alteration or discontinuation may be made which would (i) impair the right of any recipient of restricted stock or option or stock bonus already granted, without his or her written consent, or (ii) without the approval of the shareholders (A) increase the total number of shares reserved for the Stock Incentive Plan, (B) decrease the option price of an incentive stock option to less than 100% of the fair market value of the stock on the date the option was granted, (C) change the class of persons eligible to receive an award of restricted stock or options under the Stock Incentive Plan, or (D) extend the duration of the Stock Incentive Plan. The Committee may, retroactively or prospectively, amend the terms of any award of restricted stock or option already granted without the holder's consent so long as the amendment does not impair the rights of the holder. Options and Option Price The option price per share is determined by the Committee, but in the case of an incentive stock option may not be less than 100% of the fair market value of a share of Common Stock at the time the option is granted as reported on the New York Stock Exchange. Options granted under the Stock Incentive Plan will expire on a date fixed by the Committee, but not more than 10 years from the date of grant in the case of incentive stock option. Options become exercisable over a vesting period after the date of grant determined by the Committee. Payment of the option price upon exercise of an option may be made in cash, by the delivery of Common Stock already owned by the optionee, by a combination of cash and shares, or in accordance with a cashless exercise program under which shares of Common Stock may be issued directly to the optionee's broker or dealer upon receipt of the purchase price in cash from the broker or dealer. No optionee will have any rights to dividends or other rights of a shareholder with respect to his or her shares subject to the option until the optionee has given written notice of exercise and has paid in full for such shares. Tax withholding obligations may be met by a withholding of stock otherwise deliverable to the optionee under procedures approved by the Committee. Each option granted under the Stock Incentive Plan may provide for stock appreciation rights, that is, the right to exercise the option in whole or in part without payment of the option price. If an option is exercised without payment, the optionee will be entitled to receive the excess of the fair market value of the stock covered by the option on the date of exercise over the option exercise price. This amount is payable in stock or in cash or in a combination of stock and cash at the discretion of the Committee. If an optionee's employment terminates by reason of his or her retirement under one of our retirement plans or because of death or permanent disability, the optionee's option may thereafter be exercised by the optionee or by his or her estate or beneficiary within the period specified in the option (not to exceed three years from the date of termination) but not beyond the termination date of the option. Unless otherwise determined by the Committee, if an optionee's employment terminates for any reason other than retirement, death, or permanent disability the optionee's option will terminate upon termination of employment. During the optionee's lifetime, the option is exercisable only by the optionee and may not be transferable except by will or the laws of descent and distribution. No incentive stock option may be granted to an employee who owns or would own immediately before the grant of such option, directly or indirectly, stock possessing more than 10% of the total combined voting power of all classes of MasTec's stock. This restriction does not apply if, at the time such incentive stock option is granted, the option price is at least 110% of the fair market value of a share of Common Stock on the date of grant and the incentive stock option by its terms is not exercisable after the expiration of five years from the date of grant.

Restricted Stock Awards of restricted stock may be in addition to or in lieu of option grants. During the restriction period, set by the Committee, the recipient of restricted stock is not permitted to sell, transfer, pledge, or assign the shares. Shares of restricted stock become free of all restrictions if the recipient dies or his or her employment is terminated by reason of permanent disability during the restriction period, and to the extent set by the Committee, if the recipient retires under one of our retirement plans. In the event of a termination of employment during the restriction period for any other reason, all shares of restricted stock will be forfeited and revert to MasTec, except to the extent that the Committee waives the forfeiture provision with respect to all or some of the restricted stock held by the former employee. The recipient of restricted stock is entitled to vote the shares and receive all dividends paid thereon, except that dividends paid in shares of Common Stock or other property will also be subject to the same restrictions as those placed on the restricted shares. Tax withholding obligations for any grant of restricted stock may be paid in cash by the recipient or may be met by withholding Common Stock otherwise deliverable to the recipient pursuant to procedures approved by the Committee. In lieu of cash bonuses otherwise payable to eligible employees under MasTec's compensation programs, the Committee may determine that such bonuses will be paid in Common Stock or partly in Common Stock and partly in cash. Any shares of Common Stock paid as bonuses will be free of any restrictions imposed by the plan. MasTec will withhold from any cash bonuses an amount of cash sufficient to meet its tax withholding obligations with respect to both cash and Common Stock. If the cash portion of the bonus is not sufficient, the tax withholding obligations must be paid in cash by the recipient or may be met by the withholding of Common Stock otherwise deliverable to the recipient pursuant to procedures approved by the Committee. Change in Control; Recapitalization Provisions In the event of a "change in control" of MasTec, in addition to any action required or authorized by the option or award, the Committee may in its discretion recommend that the Board of Directors take certain actions as a result of, or in anticipation of, the change in control, to assure fair and equitable treatment of the employees who hold options or restricted stock, including an offer to purchase any outstanding option or restricted stock granted or issued pursuant to the Stock Incentive Plan for its cash value as determined by the Committee. However, in no event may an option be made exercisable prior to the expiration of six months from the date of grant or, in the case of an incentive stock option, after 10 years from the date it was granted. A "Change in control" is generally defined to include (i) a merger or consolidation in which MasTec is not the surviving corporation or pursuant to which any shares of MasTec are to be converted into cash, securities or other property, or any sale, lease, exchange or other transfer of all, or substantially all, of the assets of MasTec, (ii) the approval by the shareholders of any plan for the liquidation or dissolution of MasTec, (iii) subject to certain limited exceptions, the acquisition by a "person" or "group," as defined in the Stock Incentive Plan, of 33% or more of the Common Stock or (iv) if individuals constituting the "Incumbent Board," as defined in the Stock Incentive Plan, cease to constitute a majority of our Board of Directors. Adjustments will be made in the number and class of shares available under the Stock Incentive Plan and the number, class and price of shares subject to outstanding option grants to reflect changes in the Common Stock through changes in our corporate structure or capitalization such as through a merger or stock split.

Federal Income Tax Consequences The following is a brief description of the material federal income tax consequences, under existing law, to MasTec and recipients of awards under the Stock Incentive Plan: Incentive Stock Options o Neither the grant nor the exercise (while the employee is employed or within three months after termination of employment, or 12 months in the case of termination on account of disability) of an incentive stock option will be treated as the receipt of taxable income by the employee or as a deductible item by MasTec. However the difference between the fair market value of the option stock at exercise and the exercise price is treated as an "item of adjustment" for alternative minimum tax purposes. The basis of the incentive stock option for determining gain or loss for alternative minimum tax purposes will be the exercise price for the incentive stock option increased by the amount that the alternative minimum tax income was increased due to the earlier exercise of the incentive stock option. o If the employee holds shares acquired by him or her upon the exercise of an incentive option for the two-year period from the date of grant of the option and the one-year period beginning on the day after such exercise, and if he or she has been an employee of MasTec or its subsidiaries at all times from the date of grant to the day three months before exercise, or twelve months in the case of termination on account of disability, then any gain realized by the employee on a later sale or exchange of such shares will be a long-term capital gain and any loss sustained will be a long-term capital loss. MasTec will realize no tax deduction with respect to any such sale or exchange of option shares. o If the employee disposes of any shares acquired upon the exercise of an option during the two-year period from the date of grant of the option or the one-year period beginning on the day after such exercise, the employee will generally be obligated to report as ordinary income for the year in which the disposition occurred the amount by which the fair market value of such shares on the date of the exercise of the option exceeds the option price, and MasTec will be entitled to a deduction equal to the amount of such ordinary income. Any such ordinary income will increase the employee's tax basis for the purpose of determining gain or loss. If, however, a disposition occurs in the year in which the option is exercised, the maximum amount that will be included as alternative minimum tax income is the gain on the disposition of the incentive stock option stock. Should there be a disposition in a year other than the year of exercise, the income on the disposition will not be considered income for alternative minimum tax purposes. o If an option holder who has acquired stock upon the exercise of an incentive stock option makes a disposition within the two-year period described above, and the disposition is a sale or exchange with respect to which a loss (if sustained) would be recognized to the option holder, then the amount includible in the option holder's gross income, and the amount deductible by MasTec, will not exceed the excess (if any) of the amount realized on the sale or exchange over the tax basis of the stock. Non-Qualified Stock Options In the case of an option granted under the Stock Incentive Plan that is not an incentive stock option, the grant of the option will not result in taxable income to the option holder or a tax deduction to MasTec. The option holder recognizes ordinary income at the time the option is exercised in the amount by which the fair market value of the shares acquired exceeds the option price. MasTec is entitled to a corresponding ordinary income tax deduction at that time, if applicable income and social security tax withholding requirements are satisfied. The option holder's tax basis for purposes of determining gain or loss on a subsequent sale of the shares is the fair market value of the shares at the date of exercise of the option. The holding period for such shares will commence on such date and, accordingly, will not include the period during which the option was held. In the event of a sale of shares received upon exercise of the option, any gain or loss will generally be a capital gain or loss. The capital gain or loss will be a long-term capital gain or loss if the shares were held for more than one year after the date on which the option was exercised. Use of Stock to Exercise Options The payment of the option exercise price by delivery of Common Stock will constitute a non-taxable exchange by the optionee and will not affect the incentive stock option status of the Common Stock acquired in the case of an incentive stock option. However, if the Common Stock delivered in payment was previously acquired pursuant to the exercise of an incentive stock option and has not been held for the requisite one-year period, the exchange would constitute a premature disposition of such Common Stock for purposes of the incentive stock option holding requirements. Use of Common Stock in payment of the option price will result in the same tax consequences to MasTec as if the exercise were effected by a cash payment. The shares of stock received upon the exercise of an incentive or non-qualified stock option equal to the number of shares used to exercise the option will have a basis in the stock equal to the basis that the employee had in the stock used in the exercise. The remaining shares of stock will have a basis equal to the gain, if any, on the exercise of the incentive or non-qualified stock option and any cash paid on the exercise. Stock Appreciation Rights The amount received by an optionee who exercises a stock appreciation right with respect to his or her option is taxable as ordinary income at the time of exercise and MasTec is entitled to a corresponding ordinary income tax deduction. Bonus Stock The grantee will realize ordinary income during his or her taxable year in which the shares of Common Stock are issued pursuant to the award of bonus stock in an amount equal to the fair market value of the shares of Common Stock at the date of issue. MasTec is entitled to a corresponding ordinary income tax deduction. If the grantee thereafter disposes of such shares of Common Stock, any amount received in excess of the market value of the shares on the date of issue will be treated as long or short-term capital gain depending upon the holding period of the shares. Restricted Stock A grantee will not realize any taxable income upon the award of restricted stock unless a grantee elects under Section 83(b) of the Internal Revenue Code (the "Code") to have the fair market value of the Common Stock (determined without regard to the possibility of forfeiture) included in his or her gross income in the year the restricted stock is issued. In the absence of such an election, the grantee will realize ordinary income during his or her taxable year in which the possibility of forfeiture lapses. If the grantee thereafter disposes of the Common Stock, any amount received in excess of the fair market value of the shares on the date the possibility of forfeiture lapsed will be treated as long or short-term gain depending upon the holding period (measured from the date the possibility of forfeiture lapsed) of the shares. MasTec will be entitled to an ordinary tax deduction in the same amount and at the same time the grantee is considered to have realized ordinary income. Change in Control Under certain circumstances, accelerated vesting or exercise of options or stock appreciation rights, or the accelerated lapse of restrictions on restricted stock, in conjunction with a "change in control" might be deemed an "excess parachute payment" for purposes of the provisions of Section 280G of the Code. To the extent it is so considered, the optionee or grantee may be subject to a 20% excise tax and MasTec may be denied a tax deduction.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION Report of the Compensation Committee 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 and managers 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 and managers. The Committee is composed of Arthur B. Laffer, who serves as Chairman, and Olaf Olafsson, 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 and managers so as to attract and retain talented personnel, (ii) motivate executives and managers to achieve the strategic goals set by MasTec by linking an executive's or a manager'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 and managers 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 and managers 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 Committee considered a number of factors in establishing 1999 compensation, none of which were quantified, ranked or assigned relative weights. o The substantial increase in revenue and earnings in comparison to prior years. o The substantial increase in MasTec's stock price from prior years. o The significant consolidation and reorganization of MasTec's core North American infrastructure service business into more efficient service lines organized by customer groups. o The further diversification and expansion of MasTec's core business through fold-in acquisitions. o The continued divestiture of non-core assets to concentrate resources on MasTec's core business. o Individual performance Salary The base salary of executives and managers is determined initially by analyzing and evaluating the responsibilities of the position and comparing the proposed base salary with that of executives and managers 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 or manager for 1999. The Committee awarded increases in base salary to certain of the executive officers and managers of MasTec, including certain of the Named Executive Officers identified under the caption "Executive Compensation" below.

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 senior executives at both the corporate and operational levels that awards incentive bonuses based on MasTec's or an individual unit's performance as measured by earnings before interest and taxes ("EBIT") and return on assets. Awards are based on a multiple of base salary or a percentage of EBIT. A portion of the bonus is awarded in stock and stock options. MasTec or the individual unit must meet certain minimum thresholds before any bonus is earned. For 1999, the Committee awarded bonuses, including restricted stock and stock options, to certain of MasTec's executives and managers, including the Named Executive Officers, under these plans. CEO Compensation Pursuant to our existing employment agreement with Joel-Tomas Citron, our President and Chief Executive Officer, MasTec was obligated to pay Mr. Citron a bonus of $600,000 upon the achievement of a certain stock price level, which was achieved. Additionally, due to MasTec's strong performance in 1999, the Committee awarded Mr. Citron an additional bonus of $400,000, a portion of which was paid in Common Stock. The Committee also awarded Mr. Citron options to purchase 300,000 shares of Common Stock at an exercise price equal to the fair market value of the Common Stock on the date of grant. During a portion of 1999, Jorge Mas served as President and Chief Executive Officer of MasTec. For his services in 1999 and prior years, the Committee granted Mr. Mas options or stock appreciation rights with respect to 500,000 shares of Common Stock at an exercise price equal to the fair market value of the Common Stock on the date of grant. Mr. Mas continues to serve as Chairman of the Board of Directors, but is no longer an executive officer of MasTec. Compensation Committee Arthur B. Laffer Olaf Olafsson William N. Shiebler Jose S.

(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 the Common Stock on the New York Stock Exchange on the date of grant. (3) Potential gains are net of exercise price, but before taxes associated with exercise. These amounts represent certain assumed rates of appreciation only, based on Securities and Exchange Commission rules, and do not represent MasTec's estimate or projection of the price of MasTec's stock in the future. Actual gains, if any, on stock option exercises depend upon the actual future performance of MasTec's Common Stock and the continued employment of the option holders throughout the vesting period. Accordingly, the potential realizable values set forth in this table may not be achieved or may be exceeded.

Aggregate Option Exercises and Year-End Option Values The following table sets forth information with respect to each exercise of stock options during the fiscal year ended December 31, 1999 by the Named Executive Officers and the value at December 31, 1999 of unexercised stock options held by the Named Executive Officers.

Performance Table The following table compares the cumulative total shareholder return on MasTec's Common Stock from December 31, 1994 through December 31, 1999 with the cumulative total return of the S & P 500 Stock Index and a company-constructed index of (a) seven peer companies consisting of Able Telcom Holding Corp., Amerilink Corp., Arguss Holdings, Inc. Dycom Industries, Inc., International Fibercom, Inc. MYR Group, Inc., and Quanta Services, Inc., (the "Old Peer Group"), and (b) eight peer companies consisting of Able Telecom Holding Corp, Arguss Holdings, Inc., Black Box Corp., Dycom Industries, Inc., International Fibercom, Inc., LCC International Inc., Quanta Services, Inc., and Wireless Facilities Inc., (the "New Peer Group"). The table assumes that the value of the investment in the Common Stock was $100 on December 31, 1994 and that all dividends were reinvested. This data is not necessarily indicative of future results. The change in the composition of the peer group is to include new public companies that qualify as industry peers, to delete certain companies that are no longer public, and to achieve a more representative comparison of performance. 12/31/94 12/31/95 12/31/96 12/31/97 12/31/98 12/31/99 -------- -------- -------- -------- -------- -------- MasTec $100.00 $129.27 $517.07 $334.76 $307.32 $651.22 New Peer Group $100.00 $118.60 $329.91 $277.56 $341.80 $513.73 Old Peer Group $100.00 $124.16 $157.29 $291.69 $543.35 $643.93 S & P 500 $100.00 $137.58 $169.17 $225.61 $290.09 $351.13

EXHIBIT "B" MASTEC, INC. 1994 STOCK INCENTIVE PLAN (As Amended May 17, 2000) 1. Purpose. The purpose of the MasTec, Inc. 1994 Stock Incentive Plan (the "Plan") is to increase the interest of the executives, managers and other key employees of MasTec, Inc. and its subsidiaries in MasTec's business through the added incentive created by the opportunity afforded for stock ownership under the Plan. Stock ownership will provide these employees with a further stake in the future welfare of MasTec and encourage them to remain with MasTec and its subsidiaries. It is also expected that the Plan will encourage qualified persons to seek and accept employment with MasTec and its subsidiaries. Pursuant to the Plan, eligible employees will be offered the opportunity to acquire MasTec common stock ("Common Stock") through the grant of options, the award of restricted stock under the Plan, bonuses payable in stock or a combination thereof. As used in this Plan, the term "subsidiary" means any present or future corporation which is or would be a "subsidiary corporation" of MasTec as the term is defined in Section 424(f) of the Internal Revenue Code of 1986 (the "Code"). 2. Administration of the Plan. (a) Committee. The Plan will be administered by the Board of Directors of MasTec (the "Board"). The Board, however, may at any time appoint a committee (the "Committee") of two or more Board members and delegate to such Committee one or more of the administrative powers allocated to the Board pursuant to the provisions of the Plan. Members of the Committee will serve for such period of time as the Board may determine and will be subject to removal by the Board at any time. The Board may also at any time terminate the functions of the Committee and reassume all powers and authority previously delegated to the Committee. (b) Powers of the Board. Subject to the provisions of the Plan, the Board of Directors will have the authority, in its discretion: (i) to grant awards of stock options, restricted stock, stock bonuses or other awards pursuant to the terms of the Plan; (ii) to determine the fair market value of the Common Stock of MasTec; (iii) to determine the exercise price per share of options to be granted; (iv) to determine the persons to whom, and the time or times at which, options or other awards will be granted and the number of shares to be represented by each option or award; (v) to determine the vesting schedule of options to be granted; (vi) to prescribe, amend and rescind rules and regulations relating to the Plan; (vii) to determine the terms and provisions of each award granted under the Plan (which need not be identical) including, without limitation, those relating to forfeiture, payment and exercisability; (viii) to accelerate the vesting date of any award; (ix) to authorize any person to execute on behalf of MasTec any instrument required to effectuate the grant of an award previously granted by the Board; (x) subject to the provisions of the Plan and subject to such additional limitations and restrictions as the Board may impose, to delegate to specific members of management or to a committee of management personnel the authority to determine: (A) the persons to whom, and the time and times at which, awards will be granted and the number of shares to be represented by each option or award; (B) the vesting schedule of options; (C) the term of awards; and (D) other terms and conditions of any options or awards, provided that the Board will not have the authority to delegate such matters with respect to awards to be granted to any person ("Insiders") subject to Section 16 of the Securities Exchange Act of 1934 (the "Exchange Act") or any "covered employee" under Section 162(m) of the Code; and (xi) to interpret the Plan and make all other determinations deemed necessary or advisable for the administration of the Plan. The Board may require the voluntary surrender of all or any portion of any option granted under the Plan as a condition precedent to a grant of a new option to such optionee. Subject to the provisions of the Plan, such new option will be exercisable at the price, during the period and on such other terms and conditions as are specified by the Board at the time the new option is granted. Upon surrender, the options surrendered will be unexercisable and the shares previously subject to such options will be available for the grant of other options. (c) Effect of the Board's Decision. All decisions, determinations and interpretations of the Board of Directors will be final and binding on all employees of MasTec and its subsidiaries participating or eligible to participate in the Plan. 3. Agreements. Each option or stock or other awards granted pursuant to the Plan will be evidenced by an Option Agreement or Award Agreement (the "Agreement"). The Agreement will not be a precondition to the granting of options or stock or other awards; however, no person will have any rights under any option or stock or other awards granted under the Plan unless and until the optionee to whom such option or stock or other award has been granted has executed and delivered to MasTec an Agreement. The Board will prescribe the form of all Agreements. A fully executed original of the Agreement will be provided to both MasTec and the optionee. 4. Compliance with Rule 16b-3. It is the intent of MasTec that this Plan and options, stock and other awards hereunder satisfy, and be interpreted in a manner that, in the case of employees who have been granted an option or awarded stock under the Plan ("Participants") who are or may be Insiders, satisfies the applicable requirements of Rule 16b-3 of the Exchange Act, so that such persons will be entitled to the benefits of Rule 16b-3, or other exemptive rules under Section 16, and will not be subjected to avoidable liability thereunder. If any provision of this Plan or of any option, stock or other award would otherwise frustrate or conflict with the intent expressed in this Section 4, that provision to the extent possible will be interpreted and deemed amended so as to avoid such conflict. To the extent of any remaining irreconcilable conflict with such intent, such provision will be deemed void as applicable to Insiders. 5. Shares of Stock Subject to the Plan. The total number of shares that may be optioned or awarded under the Plan is 3,500,000 shares of the $0.10 par value Common Stock of MasTec (the "Common Stock") of which 1,000,000 shares may be awarded as restricted stock, subject to adjustment as provided in Paragraph 5. No employee will receive, over the term of the Plan, awards in the form of options, whether incentive stock options or options other than incentive stock options, to purchase more than 1,000,000 shares of Common Stock. Any shares subject to an option which for any reason expires or is terminated unexercised and any restricted stock which is forfeited may again be optioned or awarded under the Plan; provided, however, that forfeited shares will not be available for further awards if the employee has realized any benefits of ownership from such shares. Shares subject to the Plan may be either authorized and unissued shares or issued shares acquired by MasTec or its subsidiaries. 6. Eligibility. Key employees, including executives and managers, of MasTec and its subsidiaries (but excluding non-employee directors) are eligible to be granted options and awarded restricted stock under the Plan and to have their bonuses payable in stock. The employees who will receive awards or options under the Plan will be selected from time to time by the Board, in its sole discretion, from among those eligible, which may be based upon information furnished to the Board by MasTec's management, and the Board will determine, in its sole discretion, the number of shares to be covered by the award or awards and by the option or options granted to each such employee selected. 7. Duration of the Plan. No award or option may be granted under the Plan after January 31, 2004, but awards or options theretofore granted may extend beyond that date.

8. Terms and Conditions of Stock Options. All options granted under this Plan will be either incentive stock options, as defined in Section 422 of the Code, or options other than incentive stock options. Each such option will be subject to all the applicable provisions of the Plan, including the following terms and conditions, and to such other terms and conditions not inconsistent with the Plan as the Board may determine. (a) The option price per share will be determined by the Board. However, subject to Paragraph 8(k), the option price of incentive stock options will not be less than 100% of the fair market value of a share of Common Stock at the time the option is granted. For purposes of the Plan, the fair market value will be the mean between the highest and lowest sale prices at which the Common Stock is traded on the New York Stock Exchange on the relevant date. If no sales are available on such date, the most recent date, within a reasonable time, on which sales are available will be used. If the Common Stock is listed on a national securities exchange other than the New York Stock Exchange, the mean between the highest and lowest sale prices at which the Common Stock is traded on such exchange on such date will be used. If there is no sale of the Common Stock on such exchange on the date the option is granted, the mean between the bid and asked prices on such exchange at the close of the market on such date will be deemed to be the fair market value of the Common Stock. If the Common Stock is quoted in the over-the-counter market on the relevant date, the fair market value will be the mean between the highest and lowest sale prices at which the Common Stock is quoted in the over-the-counter market on the relevant date as reported on NASDAQ. (b) Each incentive stock option will be exercisable during and over such period ending not later than 10 years, or such later date as may be allowable under the Code, from the date it was granted, as may be determined by the Board and stated in the Agreement. Each other option will be exercisable during and over such period as may be determined by the Board and stated in the Agreement. (c) An option will not be exercisable with respect to a fractional share of Common Stock or with respect to the lesser of fifty (50) shares or the full number of shares then subject to the option. No fractional shares of Common Stock will be issued upon the exercise of an option. If a fractional share of Common Stock will become subject to an option by reason of a stock dividend or otherwise, the optionee will not be entitled to exercise the option with respect to such fractional share. (d) Each option will state whether it will or will not be treated as an incentive stock option. (e) Each option may be exercised by giving written notice to MasTec specifying the number of shares to be purchased, which will be accompanied by payment in full including applicable taxes, if any. Payment, except as provided in the Agreement, will be (A) in United States dollars by check or bank draft, or (B) by tendering to MasTec Common Stock shares already owned by the person exercising the option, which may include shares received as the result of a prior exercise of the option, and having a fair market value, as determined in Paragraph 8(a), on the date on which the option is exercised equal to the cash exercise price applicable to such option. (C) by a combination of United States dollars and Common Stock shares as aforesaid, or (D) in accordance with a cashless exercise program under which, if so instructed by the optionee, shares of Common Stock may be issued directly to the optionee's broker or dealer upon receipt of the purchase price in cash from the broker or dealer. No optionee will have any rights to dividends or other rights of a shareholder with respect to shares of Common Stock subject to his or her option until he or she has given written notice of exercise of his or her option and paid in full for such shares.

(f) Notwithstanding the foregoing, the Board may, in its sole discretion, grant to a grantee of an option the right (hereinafter referred to as a "stock appreciation right") to elect, in the manner described below, in lieu of exercising his or her option for all or a portion of the shares of Common Stock covered by such option, to relinquish his or her option with respect to any or all of such shares and to receive from MasTec a payment having a value equal to the amount by which (a) the fair market value, as determined in Paragraph 8(a), of a share of Common Stock on the date of such election, multiplied by the number of shares as to which the grantee will have made such election, exceeds (b) the total purchase price for that number of shares of Common Stock under the terms of such option. A grantee who makes such an election will receive payment in the sole discretion of the Board (i) in cash equal to such excess; or (ii) in the nearest whole number of shares of Common Stock of MasTec having an aggregate value which is not greater than the cash amount calculated in (i) above; or (iii) a combination of (i) and (ii) above. A stock appreciation right may be exercised only when the amount described in (a) above exceeds the amount described in (b) above. An election to exercise stock appreciation rights will be deemed to have been made on the day written notice of such election, addressed to the Board (Attention: Corporate Secretary) is received at MasTec's executive offices. An option or any portion thereof with respect to which a grantee has elected to exercise the stock appreciation rights described above will be surrendered to MasTec and such option will thereafter remain exercisable according to its terms only with respect to the number of shares as to which it would otherwise be exercisable, less the number of shares with respect to which stock appreciation rights have been exercised. The grant of a stock appreciation right will be evidenced by such form of Agreement as the Board may prescribe. The Agreement evidencing stock appreciation rights will be personal and will provide that they will not be transferable by the grantee otherwise than by will or the laws of descent and distribution and that they will be exercisable, during the lifetime of the grantee, only by him or her. (g) An option may be exercised only if at all times during the period beginning with the date of the granting of the option and ending on the date of such exercise, the grantee was an employee of either MasTec or of a subsidiary of MasTec or of another corporation referred to in Section 421(a)(2) of the Code, except that if such continuous employment is terminated by retirement under a retirement plan of MasTec or a subsidiary, or because of death or permanent disability, the option may be exercised within a period to be provided in the Agreement with the grantee not to exceed one year after such termination of continuous employment, but in no event later than the termination date of the option. The Board may require medical evidence of permanent disability, including medical examinations by physicians selected by it. Except as described in this Paragraph 8(g), unless otherwise provided in the Agreement, all options granted to an optionee and not previously exercised will terminate upon termination of employment. (h) The option by its terms will be personal and will not be transferable by the optionee otherwise than by will or by the laws of descent and distribution. During the lifetime of an optionee, the option will be exercisable only by the optionee. In the event any option is exercised by the executors, administrators, heirs or distributees of the estate of a deceased optionee, MasTec will be under no obligation to issue Common Stock unless and until MasTec is satisfied that the person or persons exercising the option are the duly appointed legal representative of the deceased optionee's estate or the proper legatees or distributees. (i) Notwithstanding any intent to grant incentive stock options, an option granted will not be considered an incentive stock option to the extent that it together with any earlier incentive stock options permits the exercise for the first time in any calendar year of more than $100,000 in value of Common Stock (determined at the time of grant). (j) The Board may, but need not, require such consideration from an optionee at the time of granting an option as it will determine, either in lieu of, or in addition to, the limitations on exercisability provided in Paragraph 8(g). (k) No incentive stock option will be granted to an employee who owns or would own immediately before the grant of such option, directly or indirectly, stock possessing more than 10% of the total combined voting power of all classes of stock of MasTec. This restriction does not apply if, at the time such incentive stock option is granted, the option price is at least 110% of the fair market value of one share of Common Stock, as determined in Paragraph 8(a), on the date of grant and the incentive stock option by its terms is not exercisable after the expiration of five years from the date of grant. 9. Terms and Conditions of Restricted Stock Awards. All awards of restricted stock under the Plan will be subject to all the applicable provisions of the Plan, including the following terms and conditions, and to such other terms and conditions not inconsistent therewith, as the Board may determine. (a) Awards of restricted stock may be in addition to or in lieu of option grants. (b) During a period set by the Board at the time of each award of restricted stock (the "restriction period"), the recipient will not be permitted to sell, transfer, pledge, or assign the shares of restricted stock; except that such shares may be used, if the award permits, to pay the option price of any option granted under the Plan provided an equal number of shares delivered to the optionee carry the same restrictions as the shares so used. (c) Shares of restricted stock will become free of all restrictions if the recipient dies or his employment terminates by reason of permanent disability, as determined by the Board, during the restriction period and, to the extent set by the Board at the time of the award or later, if the recipient retires under a retirement plan of MasTec or a subsidiary during such period. The Board may require medical evidence of permanent disability, including medical examinations by physicians selected by it. If the Board determines that any such recipient is not permanently disabled or that a retiree's restricted stock is not to become free of restrictions, the restricted stock held by either such recipient, as the case may be, will be forfeited and revert to MasTec. (d) Shares of restricted stock will be forfeited and revert to MasTec upon the recipient's termination of employment during the restriction period for any reason other than death, permanent disability or, to the extent determined by the Board, retirement under a retirement plan of MasTec or a subsidiary, except to the extent the Board, in its sole discretion, finds that such forfeiture might not be in the best interest of MasTec and, therefore, waives all or part of the application of this provision to the restricted stock held by such recipient. (e) Stock certificates for restricted stock will be registered in the name of the recipient but will be appropriately legended and returned to MasTec by the recipient, together with a stock power, endorsed in blank by the recipient. The recipient will be entitled to vote shares of restricted stock and will be entitled to all dividends paid thereon, except that dividends paid in Common Stock or other property will also be subject to the same restrictions. (f) Restricted stock will become free of the foregoing restrictions upon expiration of the applicable restriction period and MasTec will deliver Common Stock certificates evidencing such stock free of any restrictive legend. 10. Bonuses Payable in Stock. In lieu of cash bonuses otherwise payable under MasTec's compensation plans or practices to employees eligible to participate in the Plan, the Board, in its sole discretion, may determine that such bonuses may be payable in stock or partly in stock and partly in cash. Such bonuses will be in consideration of services previously performed and as an incentive toward future services and may consist of shares of Common Stock with or without restriction on future sale. The number of shares of Common Stock payable in lieu of an amount of each bonus otherwise payable will be determined by dividing such amount by the fair market value of one share of Common Stock on a date determined by the Board, with fair market value determined as of such date in accordance with Paragraph 8(a).

11. Change in Control. (a) In the event of a change in control of MasTec, in addition to any action required or authorized by the terms of an Agreement, the Board may, in its sole discretion, take any of the following actions as a result, or in anticipation, of any such event to assure fair and equitable treatment of Participants: (i) accelerate time periods for purposes of vesting in, or realizing gain from, any outstanding option or shares of restricted stock made pursuant to this Plan; (ii) offer to purchase any outstanding option or shares of restricted stock made pursuant to this Plan from the holder for its equivalent cash value, as determined by the Board as of the date of the change in control; or (iii)make adjustments or modifications to outstanding options or with respect to restricted stock as the Board deems appropriate to maintain and protect the rights and interests of the Participants following such change in control. Any such action will be conclusive and binding on MasTec and all Participants. (b) For purposes of this Section 11, a "change in control" will be deemed to have occurred if at any time: (1) there is consummated (i) any consolidation or merger of MasTec in which MasTec is not the continuing or surviving corporation or pursuant to which any shares of Common Stock are to be converted into cash, securities or other property, provided that the consolidation or merger is not with a corporation which was a wholly-owned subsidiary of MasTec immediately before the consolidation or merger; or (ii) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all, or substantially all, of the assets of MasTec; or (2) the shareholders of MasTec approve any plan or proposal for the liquidation or dissolution of MasTec; or (3) any "person," including a "group" as determined in accordance with Sections 13(d) and 14(d) of the Exchange Act, becomes the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act), directly or indirectly, of 33% or more of the combined voting power of MasTec's then outstanding Common Stock, provided that such person, immediately before it becomes such 33% beneficial owner, is not (i) a wholly-owned subsidiary of MasTec, (ii) an individual, or a spouse or a child of such individual, that on March 1, 1994, owned greater than 20% of the combined voting power of such Common Stock, or (iii) a trust, foundation, partnership or other entity controlled by an individual or individuals described in Paragraph 11(b)(3)(ii); or (4) individuals who constitute the Board on March 1, 1994 (the "Incumbent Board"), cease for any reason to constitute at least a majority thereof, provided that any person becoming a director subsequent to March 1, 1994, whose election, or nomination for election by MasTec's shareholders, was approved by a vote of at least three quarters of the directors comprising the Incumbent Board (either by a specific vote or by approval of the proxy statement of MasTec in which such person is named as a nominee for director, without objection to such nomination) will be, for purposes of this clause (4), considered as though such Person were a member of the Incumbent Board. (c) In no event, however, may any incentive stock option be exercised after 10 years from the date it was granted.

12. Transfer, Leave of Absence. For the purpose of the Plan: (a) a transfer of an employee from MasTec to a subsidiary or affiliate of MasTec, whether or not incorporated, or vice versa, or from one subsidiary or affiliate of MasTec to another, and (b) a leave of absence, duly authorized in writing by MasTec or a subsidiary or affiliate of MasTec, will not be deemed a termination of employment. 13. Rights of Employees. (a) No person will have any rights or claims under the Plan except in accordance with the provisions of the Plan and any agreement. (b) Nothing contained in the Plan will be deemed to give any employee the right to be retained in the service of MasTec or its subsidiaries. 14. Tax Withholding Obligations. (a) The payment of taxes, if any, upon the exercise of an option pursuant to Paragraph 8(e) or a stock appreciation right pursuant to Paragraph 8(f), will be in cash at the time of exercise or on the applicable tax date under Section 83 of the Code, if later; provided, however, tax withholding obligations may be met by the withholding of Common Stock otherwise deliverable to the optionee pursuant to procedures approved by the Board. (b) Recipients of restricted stock pursuant to paragraph 9 will be required to pay taxes to MasTec upon the expiration of restriction periods or such earlier dates as elected pursuant to Section 83 of the Code; provided, however, tax withholding obligations may be met by the withholding of Common Stock otherwise deliverable to the recipient pursuant to procedures approved by the Board. In no event will Common Stock be delivered to any awardee until he has paid to MasTec in cash the amount of tax required to be withheld by MasTec or has elected to have his withholding obligations met by the withholding of Common stock in accordance with the procedures approved by the Board or otherwise entered into an agreement satisfactory to MasTec providing for payment of withholding tax. (c) MasTec will withhold from any cash bonus described in Paragraph 10, an amount of cash sufficient to meet its tax withholding obligations. 15. Changes in Capital. Upon changes in the outstanding Common Stock by reason of a stock dividend, stock split, reverse split, subdivision, recapitalization, merger, consolidation (whether or not MasTec is a surviving corporation), an extraordinary dividend payable in cash or property, combination or exchange of shares, separation, reorganization or liquidation, the aggregate number and class of shares available under the Plan as to which stock options and restricted stock may be awarded, the number and class of shares under each option and the option price per share will be correspondingly adjusted by the Board, such adjustments to be made in the case of outstanding options without change in the total price applicable to such options. 16. Miscellaneous Provisions. (a) The Plan will be unfunded. MasTec will not be required to establish any special or separate fund or to make any other segregation of assets to assure the issuance of shares upon exercise of any option under the Plan and issuance of shares upon exercise of options will be subordinate to the claims of MasTec's general creditors. Proceeds from the sale of shares of Common Stock pursuant to options granted under this Plan will constitute general funds of MasTec. The expenses of the Plan will be borne by MasTec. (b) It is understood that the Board may, at any time and from time to time after the granting of an option or the award of restricted stock or bonuses payable in Common Stock hereunder, specify such additional terms, conditions and restrictions with respect to such option or stock as may be deemed necessary or appropriate to ensure compliance with any and all applicable laws, including, but not limited to, terms, restrictions and conditions for compliance with federal and state securities laws and methods of withholding or providing for the payment of required taxes. (c) If at any time the Board will determine, in its discretion, that the listing, registration or qualification of shares of Common Stock upon any national securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of, or in connection with, the sale or purchase of shares of Common Stock hereunder, no option or stock appreciation right may be exercised or restricted stock or stock bonus may be transferred in whole or in part unless and until such listing, registration, qualification, consent or approval will have been effected or obtained, or otherwise provided for, free of any conditions not acceptable to the Board in the exercise of its reasonable judgment. (d) By accepting any benefit under the Plan, each Participant and each person claiming under or through such person will be conclusively deemed to have indicated his acceptance and ratification, and consent to, any action taken under the Plan by the Board MasTec or the Board. (e) The Plan will be governed by and construed in accordance with the laws of the State of Florida. 17. Limits of Liability. (a) Any liability of MasTec or a subsidiary of MasTec to any Participant with respect to an option or stock or other award will be based solely upon contractual obligations created by the Plan and the Agreement. (b) Neither MasTec nor a subsidiary of MasTec, nor any member of the Board, nor any other person participating in any determination of any question under the Plan, or in the interpretation, administration or application of the Plan, will have any liability to any party for any action taken or not taken in connection with the Plan, except as may expressly be provided by statute. 18. Amendments. The Board may amend, alter or discontinue the Plan, at any time, including without limitation amendments necessary to qualify for an exemption or to comply with applicable law or regulations, provided, however, no amendment, alteration or discontinuation will be made which would impair the rights of any holder of an award of restricted stock or option or stock bonus theretofore granted, without his or her written consent, or which, without the approval of MasTec"s shareholders, would: (a) except as is provided in Paragraph 15, increase the maximum number of shares of Common Stock reserved for the purpose of the Plan; (b) except as is provided in Paragraphs 8(f) and 15 of the Plan, decrease the option price of an incentive stock option to less than 100% of the fair market value, as determined in Paragraph 8(a), of a share of Common Stock on the date of the granting of the option; (c) change the class of persons eligible to receive an award of restricted stock or options under the Plan; or (d) extend the duration of the Plan. The Board may amend the terms of any award of restricted stock or option theretofore granted, retroactively or prospectively, but no such amendment will impair the rights of any holder without his or her written consent. 19. Duration. The Plan will terminate upon the earlier of the following dates or events to occur: (a) upon the adoption of a resolution of the Board terminating the Plan; or (b) January 31, 2004. No such termination of the Plan will affect the rights of any Participant hereunder and all options previously granted and restricted stock and stock bonus awarded hereunder will continue in force and in operation after the termination of the Plan, except as they may be otherwise terminated in accordance with the terms of the Plan.
