6 PROPOSAL ONE ELECTION OF DIRECTORS GENERAL The Company's Amended and Restated Certificate of Incorporation, as amended, and bylaws provide that the number of directors on the Board shall be fixed from time to time by the Board of Directors but shall not be less than one nor more than fifteen persons. The Certificate of Incorporation divides the Board of Directors into three classes, designated as Class I, Class II and Class III. Each class of directors is to be elected to serve a three-year term and is to consist, so far as possible, of one-third of the number of directors required at the time to constitute a full Board. If the number of directors is not evenly divided into thirds, the Board of Directors shall determine which class or classes shall have one extra director. The Board of Directors presently consists of eleven directors, four in Class I, four in Class II and three in Class III, whose terms of office expire with the 2002, 2000 and 2001 annual meetings, respectively, and until their successors are elected and qualified. The holders of the Restricted Common Stock are entitled to elect one director and are not entitled to vote on other directors. The term of office of each of the current Class II Directors expires at the time of the 2000 Annual Meeting of Stockholders, or as soon thereafter as their successors are elected and qualified. Each of Messrs. Mills, Muth, Pollock and Tucker have been nominated to serve an additional three-year term as Class II Directors to be elected by the holders of the Common Stock. Each of Messrs. Mills, Muth, Pollock and Tucker has consented to be named in this Proxy Statement and to serve as a director if elected. It is the intention of the persons named in the accompanying proxy card to vote for the election of all four nominees named below unless a stockholder has withheld such authority. The affirmative vote of holders of a plurality of the Common Stock present in person or by proxy at the 2000 Annual Meeting of Stockholders and entitled to vote is required for election of the nominees. If, at the time of or prior to the 2000 Annual Meeting of Stockholders, any of the nominees should be unable or decline to serve, the discretionary authority provided in the proxy may be used to vote for a substitute or substitutes designated by the Board of Directors. The Board of Directors has no reason to believe that any substitute nominee or nominees will be required. No proxy will be voted for a greater number of persons than the number of nominees named herein. NOMINEES -- CLASS II DIRECTORS (TERMS EXPIRING AT THE 2003 ANNUAL MEETING OF STOCKHOLDERS) JERRY M.

(the "Committee") is pleased to present the 1999 report on executive compensation. This report of the Committee documents the components of the Company's executive officer compensation program and describes the basis on which the compensation program determinations were made by the Committee with respect to the executive officers of the Company. The Committee meets regularly and is comprised of Messrs. Hodel, Sielbeck and Tucker. The duty of the Committee is to review compensation levels of members of management, as well as administer the Company's various incentive plans including its annual bonus plan and its stock option plan. EXECUTIVE COMPENSATION PROGRAM PHILOSOPHY The Company's compensation philosophy, since its formation, has been (i) to compensate its executive officers at a base level that is at least equal to the average salaries paid by companies of similar size; (ii) to provide the opportunity for its executive officers to earn additional compensation in the form of annual bonuses if certain financial performance goals are met; and (iii) to closely align the interests of the executive officers with those of the stockholders through substantial equity ownership positions. The Company has entered into employment agreements with certain executive officers. See "Employment Agreements." Additionally, in order to attract these officers, and ensure that their long-term interests would be in line with those of stockholders, the Company allowed certain of them to purchase Common Stock during the initial phase of the Company's operations. BASE SALARY The salaries paid to the executive officers during fiscal 1999 were paid pursuant to the employment agreements referenced above or according to salaries negotiated at the time of initial hire, with raises given to certain of the executive officer's effective December 1, 1998. The Committee believes, based on consultations with compensation consultants, that these salaries are below executive officers' compensation in similar companies; however, the Committee intends to insure that the executive officer's compensation becomes consistent with its stated policies. Therefore as part of its responsibilities and as the Company grows from its start-up phase, the Committee will review the salaries for the Company's executive officers. The Committee intends to base individual salary changes on a combination of factors such as the performance of the executive, salary level relative to the competitive market, level of responsibility, growth of company operations and the recommendation of the Chief Executive Officer. INCENTIVE COMPENSATION Certain of the Company's executive officers, including its chief executive officer, were eligible for bonuses for fiscal 1999 based on the Company exceeding certain budgeted goals, including net income, by a higher than expected margin. The bonuses were intended to not be paid if the goals were met, but were to be paid at competitive amounts if the budgeted goals were exceeded. Such budgeted goals were generally met, but not exceeded, in 1999. CHIEF EXECUTIVE OFFICER COMPENSATION Mr. Wise's base salary for fiscal year 1999 was $225,000. This amount was set when Mr. Wise was made Chief Executive Officer. Mr. Pollock's base salary for fiscal year 1999 was $225,000. This amount was paid pursuant to his employment contract. See "Employment Agreements." 7

11 No member of the Committee is a former or current officer or employee of the Company or any of its subsidiaries. The following members of the Compensation Committee have delivered the foregoing report. Donald Paul Hodel Alan R. Sielbeck Richard L. Tucker The foregoing report and the performance graph and related description included in this proxy statement shall not be deemed to be filed with the Securities and Exchange Commission except to the extent the Company specifically incorporates such items by reference into a filing under the Securities Act of 1933 or Securities Exchange Act of 1934.

The material assumptions and adjustments incorporated into the Black-Scholes model in making such calculations include the following: (1) an interest rate representing the interest rate on U.S. Treasury securities with a maturity date corresponding to the option term; (2) volatility determined using daily prices for the Company's Common Stock during the year ended September 30, 1999; (3) a dividend rate of $0; and (4) an expected option term of six years. The ultimate values of the options will depend on the future market prices of the Common Stock, which cannot be forecast with reasonable accuracy. The actual value, if any, that an optionee will recognize upon exercise of an option will depend on the difference between the market value of the Common Stock on the date the option is exercised and the applicable exercise price.

Each agreement is subject to annual review by the Compensation Committee. In addition, these employment agreements generally restrict these individuals from competing with the Company for a period of two years after the date of the termination of employment with the Company. In the event of a change of control of the Company, such employees may be entitled to the then remaining benefits under the agreements. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS Pursuant to several 5-year lease agreements effective November 1, 1997, Bexar-Calhoun agreed to lease certain facilities owned by Mr. Weik and his immediate family. Such lease agreements provide for an annual rent of approximately $166,580, which the Company believes is not in excess of fair rental value for such facilities. Muth Electric, Inc. ("Muth") provides certain real estate management services to Muth Properties, L.L.C. From October 1, 1998 to September 30, 1999, the fees for such services equaled approximately $60,000. Muth has completed various electrical contracts for Pine Lane Estates, L.L.C., of which Mr. Muth is a member. One was completed since October 1, 1998 for $56,000. Pursuant to several 5-year lease agreements effective January 30, 1998, Muth Electric, Inc. agreed to lease certain facilities owned by Muth Properties, L.L.C. of which Mr. Muth is a member. Such lease agreements provide for an annual rent of approximately $120,700, which the Company believes is not in excess of fair rental value for such facilities. Pursuant to a 5-year lease agreement effective January 21, 1998, Ace Electric, Inc. agreed to lease certain facilities owned by Stalvey Rentals, a general partnership of which Mr. Stalvey is a partner. Such lease agreement provides for an annual rent of $115,696, which the Company believes is not in excess of fair rental value for such facilities. Pursuant to several 5-year lease agreements effective November 1, 1997. Mills Electrical Contractors agreed to lease certain facilities owned by Mr. Mills. The lease agreements provide for an annual rent of approximately $178,200, which the Company believes is not in excess of fair rental value for such facilities. J M Aviation, Inc. of which Mr. Mills is the sole stockholder received $148,489 from the Company for reimbursement travel related expenses. The Company believes such expenses were not in excess of fair market value. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During fiscal 1999, no executive officer of the Company served as (i) a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Board of Directors of the Company, or (ii) a director of another entity, one of whose executive officers served on the Board of Directors of the Company or its subsidiaries. During fiscal 1999, no member of the compensation committee (or board committee performing equivalent functions) (i) was an officer or employee of the Company, (ii) was formerly an officer of the Company or (iii) had any business relationship or conducted any transactions with the Company. COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934 Section 16(a) of the Securities Exchange Act of 1934 requires the Company's directors, executive officers and persons holding more than ten percent of a registered class of the Company's equity securities to file with the Securities and Exchange Commission ("SEC") and any stock exchange or automated quotation system on which the Common Stock may then be listed or quoted (i) initial reports of ownership, (ii) reports of changes in ownership and (iii) annual reports of ownership of Common Stock and other equity securities of 10

14 the Company. Such directors, officers and ten-percent stockholders are also required to furnish the Company with copies of all such filed reports. Based solely upon review of the copies of such reports furnished to the Company and written representations that no other reports were required during 1999, the Company believes that, other than the late filing of the forms for an option grant made to each of Messrs. Sielbeck, Tucker, Hodel, Stalvey, Muth and Weik and of the form for a purchase of Company stock by Mr. Neil DePascal, an officer of the Company, all Section 16(a) reporting requirements related to the Company's directors and executive officers were timely fulfilled during 1999. PROPOSAL TWO APPROVAL OF AUDITORS The Board of Directors has appointed Arthur Andersen LLP as the Company's independent public accountants for the fiscal year ending September 30, 2000, subject to ratification by the Company's stockholders. Arthur Andersen LLP has served as the Company's independent public accountants since the Company's inception. Representatives of Arthur Andersen LLP are expected to be present at the Annual Meeting of Stockholders and will have an opportunity to make a statement, if they desire to do so, and to respond to appropriate questions from those attending the meeting. The affirmative vote of holders of a majority of the shares of Common Stock voted at the 2000 Annual Meeting of Stockholders is required to ratify the appointment of Arthur Andersen LLP as the Company's independent public accountants for fiscal 2000. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" RATIFICATION OF ARTHUR ANDERSEN LLP'S APPOINTMENT, AND PROXIES EXECUTED AND RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON. PROPOSAL THREE APPROVAL OF EMPLOYEE STOCK PURCHASE PLAN The Board of Directors of the Company, on November 10, 1999, unanimously approved the Employee Stock Purchase Plan (the "Plan") and directed that the Plan be submitted to the stockholders for their approval at the 2000 Annual Meeting of Stockholders. The Plan will become effective, subject to stockholder approval, on February 9, 2000. Under the Plan, eligible employees may purchase up to 1,000,000 shares of the Company's Common Stock, par value $.01 per share. The Plan is being presented to the stockholders of the Company for approval to enable the Plan to qualify under Section 423 of the Internal Revenue Code of 1986, as amended (the "Tax Code"). A discussion of the tax consequences of the Plan is set forth below. The Plan is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended, or Section 401(a) of the Tax Code. The Company is unable to determine the amount of the benefits which may be received by Plan participants, or would have been received by Plan participants had the Plan been in effect for fiscal year 2000, as participation may vary in the discretion of the individual employees. Set forth below is a summary of the major provisions of the Plan, which is qualified in its entirety by reference to the full text of the Plan attached to this Proxy Statement as Appendix A. Summary of the Stock Purchase Plan Objective. The objective of the Plan is to permit employees of the Company and its subsidiaries to acquire an equity interest in the Company through the purchase of the Company's Common Stock. 11

15 Eligibility and Participation. Each employee of the Company or any of its subsidiaries who has completed at least 90 days of service with the Company is eligible to participate in the Plan except employees who are customarily employed less than 20 hours per week or less than five months per year or are employed by a subsidiary which has not adopted the Plan. However, no employee is eligible who would own, after purchasing Common Stock subject to options, shares of capital stock representing 5% or more of the total combined voting stock of the Company. The Company estimates that approximately 10,000 employees of the Company and its subsidiaries will be eligible to participate in the Plan. An eligible employee may enroll in the Plan as of April 1 for the initial Plan period and on each January 1 for all subsequent Plan periods (the "Enrollment Date") and may thereafter make contributions on an after-tax basis through payroll deductions over a nine month period for the initial Plan period and over a twelve month period for all subsequent Plan periods ending on December 31, respectively, ranging from a minimum of $5/weekly, $10/bi-weekly and $11/semi-monthly up to an overall maximum of $25,000. A participant may withdraw from the Plan at any time, in which event any accumulated payroll deductions will be paid to him. Purchase of Common Stock. On each December 31, the participants' payroll deductions since the preceding Enrollment Date will be invested in shares of Common Stock. Shares will be purchased at a price equal to 85% of the Fair Market Value (as defined in the Plan) of such Common Stock on the Enrollment Date or the date of purchase, whichever is lower. The shares purchased may be authorized but unissued shares and/or shares previously issued and reacquired by the Company. Recapitalization. In the event of any reorganization, stock split, reverse stock split or other change in the capital structure of the Company, the Compensation Committee may make an appropriate adjustment to the number, kind and purchase price of the shares available for purchase under the Plan and the maximum number of shares which may be issued under the Plan. Costs of Administration. The Company and its subsidiaries will pay the costs of administering the Plan. Taxes. The Plan is intended to qualify as an "employee stock purchase plan" under Section 423 of the Tax Code. This section provides that participants will not be taxed on the discount until the participant disposes of the stock, and the determination of the ordinary and capital portion of the resulting gain or loss depends on the length of time the employee has held the stock. The Company will be entitled to a deduction equal to the amount of the employee's ordinary income if the employee disposes of the shares within two years of the applicable Enrollment Date; otherwise, the Company will have no tax consequences. Plan Amendment. The Board of Directors of the Company may terminate and amend the Plan, at their discretion, at any time as permitted by law. However, no amendment that requires stockholder approval in order for the Plan to meet the requirements of Section 423 will be effective unless within one year after it is adopted by the Board of Directors it is approved by the Company's stockholders. Administration. A Committee appointed by the Board of Directors will administer the Plan. The Committee is empowered to adopt rules and regulations concerning the administration and interpretation of the Plan. The affirmative vote of at least a majority of the outstanding shares present in person or by proxy at the annual meeting is necessary for the adoption of the Plan. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" APPROVAL OF THE EMPLOYEE STOCK PURCHASE PLAN, AND PROXIES EXECUTED AND RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON. DEADLINE FOR SUBMISSION OF STOCKHOLDER PROPOSALS Pursuant to the Company's bylaws, stockholder proposals submitted for consideration at the Company's 2000 Annual Meeting of Stockholders must be delivered to the Corporate Secretary no later than 10 days after December 29, 1999 the date this Proxy Statement was mailed.

16 accompanied by a written statement to the extent required by applicable securities laws, the Company may exercise discretionary voting authority over proxies with respect to such proposal if presented at the Company's 2000 Annual Meeting of Stockholders. Pursuant to the Company's bylaws, stockholder proposals submitted for consideration at the company's 2001 Annual Meeting of Stockholders must be delivered to the Corporate Secretary no later than 80 days before the date of the 2001 Annual Meeting of Stockholders; provided, however, that in the event that less than 90 days notice or prior public disclosure of the date of the meeting is given or made to stockholders, notice by the stockholder to be timely must be received no later than the close of business on the tenth day following the date of which such notice was mailed or such public disclosure made. If such timely notice of a stockholder proposal is not given, the proposal may not be brought before the Annual Meeting. If timely notice is given but is not accompanied by a written statement to the extent required by applicable securities laws, the Company may exercise discretionary voting authority over proxies with respect to such proposal if presented at the Company's 2001 Annual Meeting of Stockholders. A proposal of a stockholder intended to be presented at the next annual meeting must be received at the Company's principal executive offices no later than August 30, 2000 if the stockholder making the proposal desires such proposal to be considered for inclusion in the Company's proxy statement and form of proxy relating to such meeting.

(c) A Participant's election shall remain in effect for each successive Option Period unless the Participant changes or terminates such election prior to the beginning of the Option Period in accordance with the procedures established by the Committee. 8. Payroll Deductions. (a) All Participant contributions to the Plan shall be made by payroll deductions only. At the time a Participant files the enrollment agreement with respect to an Option Period, the Participant shall authorize payroll deductions to be made on each payroll date during the Option Period in an amount equal to a designated number of whole dollars per week, but not less than $5.00 per week, in the case of a Participant who is paid weekly, $10 per bi-weekly pay period, in the case of a Participant who is paid bi- weekly, or $11.00 per semi-monthly pay period, in the case of a Participant who is paid semi-monthly; provided, however, with respect to a Participant making a minimum contribution each pay period, the last payroll deduction in the Option Period shall be reduced, if and to the extent as necessary, so that the maximum aggregate amount of minimum contributions that may be made for that Option Period is the same for all Participants, whether on a weekly, bi-weekly or semi-monthly pay period. Subject to the limitation set forth in Section 9(b), there shall be no maximum amount of payroll deduction which a Participant may authorize each periodic pay period. Such authorization shall be in writing and on such forms as provided by the Committee. (b) All payroll deductions made for a Participant may be deposited in the Company's general corporate account and shall be credited to the Participant's Account under the Plan. No interest shall accrue or be credited with respect to the payroll deductions of a Participant under the Plan. A Participant may not make any additional payments into such Account. Pending application of the Accounts, the Company may, but shall not be obligated to, segregate the payroll deductions. (c) Except as provided in Section 11, a Participant may not change his current contribution election during an Option Period. 9. Grant of Options. (a) Subject to the limitations set forth in Sections 3 and 9(b) hereof, each Participant shall be granted an option on the Enrollment Date to purchase on the Exercise Date for such Option Period (at the Exercise Price for such Option Period) a number of whole shares of the Company Stock determined A-3

22 by dividing such Participant's payroll deductions accumulated during the Option Period by the Exercise Price for such Option Period. (b) Notwithstanding any provision of the Plan to the contrary, no Participant shall be granted an option under the Plan (i) if, immediately after the grant, such Participant (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any Subsidiary of the Company, or (ii) which permits such Participant's rights to purchase stock under all employee stock purchase plans of the Company and its Subsidiaries to accrue at a rate which exceeds $25,000 of the Fair Market Value of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time. 10. Exercise of Options. Unless a Participant withdraws or is deemed to have withdrawn from the Plan during an Option Period as provided in Section 11, the Participant's option for the purchase of shares for an Option Period will be exercised automatically on the Exercise Date for such Option Period, and the maximum number of whole shares subject to the option will be purchased for the Participant at the applicable Exercise Price with the accumulated payroll deductions then credited to the Participant's Account. The certificates for such purchased shares shall be issued by the Company as soon as reasonably practical following the Exercise Date. Any amounts remaining credited to an Account after being applied as provided in the preceding sentence shall continue to be credited to the Account for the next Option Period, unless the Participant requests in writing the return of such remainder prior to the beginning of such Option Period. 11. Withdrawal; Termination of Employment. (a) A Participant may withdraw all, but not less than all, of the payroll deductions credited to the Participant's Account under the Plan at any time prior to an Exercise Date by giving written notice to the Company. All of the Participant's payroll deductions credited to the Participant's Account will be paid to him promptly after receipt of the Participant's notice of withdrawal, the Participant's participation in the Plan will be automatically terminated, and no further payroll deductions for the purchase of shares will be made. Payroll deductions will not resume on behalf of a Participant who has withdrawn from the Plan unless written notice is delivered to the Company within the enrollment period preceding the commencement of a new Option Period directing the Company to resume payroll deductions and the former Participant is at that time an Eligible Employee. (b) In the event a Participant ceases to be an Eligible Employee prior to the Exercise Date of an Option Period for any reason other than retirement on or after reaching age 65, disability under a Company long-term disability plan, Social Security or other determination made by the Committee on a nondiscriminatory basis, or death, the payroll deductions credited to the Participant's Account will be automatically returned to the Participant and the Participant's options to purchase shares under the Plan will be automatically terminated for such Option Period. (c) In the event a Participant ceases to be an Eligible Employee during an Option Period due to his retirement on or after reaching age 65, his disability under a Company long-term disability plan, Social Security or other determination made by the Committee on a nondiscriminatory basis, or his death, no further contributions may be made to the Participant's Account, and the balance of his Account at such time shall be applied to exercise his options at the end of that Option Period as provided in Section 10. (d) A Participant's withdrawal during an Option Period will not affect the Participant's eligibility to participate in a succeeding Option Period. 12. Transferability. Options to purchase Company Stock granted under the Plan are not transferable by a Participant (other than by will or the laws of descent and distribution) and are exercisable only by the Participant. A-4

23 13. Adjustments Upon Changes in Capitalization. (a) If the outstanding shares of Company Stock are increased or decreased, or are changed into or are exchanged for a different number or kind of shares, as a result of one or more reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends or the like, upon authorization of the Committee, appropriate adjustments may be made in the number and/or kind of shares, and the per share option price thereof, which may be issued in the aggregate and to any Participant upon exercise of options granted under the Plan. (b) In the event of the proposed dissolution or liquidation of the Company, each Option Period will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Committee determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the Participant shall have the right to exercise the option as to all of the optioned stock, including shares as to which the option would not otherwise be exercisable. If the Committee makes an option fully exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Committee shall notify the Participant that the option shall be fully exercisable for a stated period, which shall not be less than 10 days from the date of such notice, and the option will terminate upon the expiration of such period. (c) In all cases, the Committee shall have full discretion to exercise any of the powers and authority provided under this Section 13, and the Committee's actions hereunder shall be final and binding on all Participants. No fractional shares of stock shall be issued under the Plan pursuant to any adjustment authorized under the provisions of this Section 13. 14. Amendment of the Plan. The Board or the Committee may at any time, or from time to time, amend the Plan in any respect; provided, however, that the Plan may not be amended in any way that will cause rights issued under the Plan to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Code or any successor thereto, including, without limitation, stockholder approval if required. 15. Termination of the Plan. The Plan and all rights of Eligible Employees hereunder shall terminate: (a) on the Exercise Date that Participants become entitled to purchase a number of shares greater than the number of reserved shares remaining available for purchase under the Plan; or (b) at any time, at the discretion of the Board. In the event that the Plan terminates under circumstances described in Section 15(a) above, reserved shares remaining as of the termination date shall be sold to Participants on a pro rata basis based on their Account balances and any amounts remaining in their Accounts returned to the Participants. 16. Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 17. Stockholder Approval. The Plan shall be subject to approval by the stockholders of the Company within twelve months after the date the Plan is adopted by the Board. If such stockholder approval is not obtained at the 2000 annual meeting of stockholders of the Company, the Plan shall not become effective. A-5

24 18. Conditions Upon Issuance of Shares. (a) The Plan, the grant and exercise of options to purchase shares of Company Stock under the Plan, and the Company's obligation to sell and deliver shares upon the exercise of options to purchase shares shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may, in the opinion of counsel for the Company, be required. In the event the Company is required to obtain from any commission or agency authority to issue any stock certificate, the inability of the Company to obtain from any such commission or agency authority that counsel for the Company deems necessary for the lawful issuance of any such certificate will relieve the Company from liability to any Participant, except to return to him the amount of the balance in his account. (b) The Company may make such provisions as it deems appropriate for withholding of amounts that the Company determines it is required to withhold pursuant to applicable tax laws in connection with the purchase or sale by a Participant of any Company Stock acquired pursuant to the Plan. The Company may require a Participant to satisfy any relevant tax requirements before authorizing any issuance of Company Stock to such Participant. A-6
