SMITH Chairman of the Board and Chief Executive Officer Huntsville, Alabama March 8, 2000 PLEASE READ THE ATTACHED PROXY STATEMENT AND THEN PROMPTLY COMPLETE, EXECUTE AND RETURN THE ENCLOSED PROXY CARD IN THE ACCOMPANYING POSTAGE-PAID ENVELOPE. IF YOU ATTEND THE ANNUAL MEETING, YOU MAY REVOKE THE PROXY CARD AND VOTE IN PERSON IF YOU SO DESIRE. ADTRAN, Inc. 901 Explorer Boulevard Huntsville, Alabama 35806 PROXY STATEMENT FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD APRIL 21, 2000 This Proxy Statement is furnished to the stockholders of ADTRAN, Inc. (the "Company") in connection with the solicitation of proxies by the Board of Directors of the Company to be voted at the 2000 Annual Meeting of Stockholders and at any adjournments thereof (the "Annual Meeting"). The Annual Meeting will be held at the headquarters of the Company, 901 Explorer Boulevard, Huntsville, Alabama, on Friday, April 21, 2000, at 10:30 a.m., local time. The approximate date on which this Proxy Statement and form of proxy card are first being sent or given to stockholders is March 8, 2000. VOTING General The securities that can be voted at the Annual Meeting consist of common stock of the Company, $.01 par value per share (the "Common Stock"), with each share entitling its owner to one vote on each matter submitted to the stockholders. The record date for determining the holders of Common Stock who are entitled to receive notice of and to vote at the Annual Meeting is March 1, 2000. On the record date, 39,445,813 shares of Common Stock were outstanding and eligible to be voted at the Annual Meeting. Quorum and Vote Required The presence, in person or by proxy, of a majority of the outstanding shares of Common Stock of the Company is necessary to constitute a quorum at the Annual Meeting. In counting the votes to determine whether a quorum exists at the Annual Meeting, the proposal receiving the greatest number of all votes "for" or "against" and abstentions (including instructions to withhold authority to vote) will be used. In voting with regard to the proposal to elect directors (Proposal 1), stockholders may vote in favor of all nominees, withhold their votes as to all nominees or withhold their votes as to specific nominees. The vote required to approve Proposal 1 is governed by Delaware law and is a plurality of the votes cast by the holders of shares entitled to vote, provided a quorum is present. As a result, in accordance with Delaware law, votes that are withheld will be counted in determining whether a quorum is present but will have no other effect on the election of directors. In voting with regard to the proposal to ratify the directors' appointment of independent accountants (Proposal 2), stockholders may vote in favor of the proposal or against the proposal or may abstain from voting. The vote required to approve Proposal 2 is governed by Delaware law and is the affirmative vote of the holders of a majority of the shares represented and entitled to vote at the Annual Meeting, provided a quorum is present. As a result, abstentions will be considered in determining whether a quorum is present and the number of votes required to obtain the necessary majority vote and therefore, will have the same legal effect as voting against the proposal. In voting with regard to the proposal to ratify an increase in the aggregate number of shares of Common Stock of the Company authorized for issuance under the 1996 Employees Incentive Stock Option Plan from 2,488,100 to 5,488,100 of Common Stock of the Company (Proposal 3), stockholders may vote in favor of the proposal or against the proposal or may abstain from voting. The vote required to approve Proposal 3 is governed by Delaware law and is the affirmative vote of the holders of a majority of the shares represented and entitled to vote at the Annual Meeting, provided a quorum is present. As a result, abstentions will be considered in determining whether a quorum is present and the number of votes required to obtain the necessary majority vote and therefore, will have the same legal effect as voting against the proposal. Under the rules of the New York and American Stock Exchanges (the "Exchanges") that govern most domestic stock brokerage firms, member firms that hold shares in street name for beneficial owners may, to the extent that such beneficial owners do not furnish voting instructions with respect to any or all proposals submitted for stockholder action, vote in their discretion upon proposals which are considered "discretionary" proposals under the rules of the Exchanges. Member brokerage firms that have received no instructions from their clients as to "non-discretionary" proposals do not have discretion to vote on these proposals. Although "broker non-votes" will be considered in determining whether a quorum exists at the Annual Meeting, "broker non-votes" will not be considered as votes cast in determining the outcome of any proposal. The Company believes that each of the three proposals to be considered at the Annual Meeting is discretionary. As of March 1, 2000 (the record date for the Annual Meeting), the directors and executive officers of the Company beneficially owned or controlled approximately 18,204,443 shares of Common Stock of the Company, constituting approximately 46.2% of the outstanding Common Stock. The Company believes that the holders of more than a majority of the Common Stock outstanding on the record date will vote all of their shares of Common Stock in favor of each of the three proposals and, therefore, that the presence of a quorum and the approval of the proposals is reasonably assured. Proxies Stockholders should specify their choices with regard to each of the three proposals on the enclosed proxy card. All properly executed proxy cards delivered by stockholders to the Company in time to be voted at the Annual Meeting and not revoked will be voted at the Annual Meeting in accordance with the directions noted thereon. In the absence of such instructions, the shares represented by a signed and dated proxy card will be voted "FOR" the election of all director nominees, "FOR" the ratification of the appointment of independent accountants and "FOR" an increase in the aggregate number of shares of Common Stock authorized for issuance under the 1996 Employees Incentive Stock Option Plan. If any other matters properly come before the Annual Meeting, the persons named as proxies will vote upon such matters according to their judgment. Any stockholder delivering a proxy has the power to revoke it at any time before it is voted by giving written notice to Charlene Little, Assistant Secretary of the Company, at 901 Explorer Boulevard, Huntsville, 2 Alabama 35806 (for overnight delivery) or at P.O. Box 140000, Huntsville, Alabama 35814-4000 (for mail delivery), by executing and delivering to Ms. Little a proxy card bearing a later date or by voting in person at the Annual Meeting; provided, however, that under the rules of the Exchanges, as followed by the Nasdaq National Market, any beneficial owner of the Company's Common Stock whose shares are held in street name by a member brokerage firm may revoke his proxy and vote his shares in person at the Annual Meeting only in accordance with applicable rules and procedures of the Exchanges, as employed by the beneficial owner's brokerage firm. In addition to soliciting proxies through the mail, the Company may solicit proxies through its directors, officers and employees in person and by telephone or facsimile. Brokerage firms, nominees, custodians and fiduciaries also may be requested to forward proxy materials to the beneficial owners of shares held of record by them. All expenses incurred in connection with the solicitation of proxies will be borne by the Company. Share Ownership of Principal Stockholders and Management The following table sets forth information regarding the beneficial ownership of the Company's Common Stock as of December 31, 1999, (i) by each person known to the Company to be the beneficial owner of more than 5% of the Company's Common Stock, (ii) each director of the Company, (iii) each of the executive officers of the Company named in the Summary Compensation Table herein and (iv) all directors and executive officers of the Company as a group, based in each case on information furnished to the Company by such persons.

The report specifically reviews the methods employed in setting the compensation of the Company's Chairman of the Board and Chief Executive Officer (the "Chief Executive Officer") and generally with respect to all executive officers. For 1999, the compensation of the Chief Executive Officer was established by the Board of Directors without any reference to quantitative measures of individual or Company performance but based instead solely on the Board's subjective evaluation of the performance of the Chief Executive Officer and the Company. The compensation paid to the Company's other executive officers for 1999 was established by the Chief Executive Officer in his discretion and was recommended by him to the Board of Directors for approval. Similar to the establishment of the Chief Executive Officer's compensation by the Board of Directors, the Chief Executive Officer based the compensation levels of the other executive officers not on any quantitative 10 measures of individual or Company performance but upon his subjective evaluation of the performance of the individual executive officers and the Company. The Board of Directors approved the recommendations of the Chief Executive Officer with regard to the 1999 compensation of each of the other executive officers of the Company. In 1997, the Board of Directors established a bonus incentive compensation program (the "Bonus Program") for certain executive officers of the Company. Bonuses granted under the Bonus Program are determined by a formula based on (i) targeted increases in per share after tax earnings of the Company from the end of a fiscal year to the end of the following fiscal year and (ii) achievement of specified operational targets on a divisional level such as unit volume targets and revenue targets. In addition, from time to time, the Chief Executive Officer has granted additional bonuses to executive officers based upon his assessment of their individual performance; however, no individual performance bonuses were granted in 1999. Limitations on the Deductibility of Executive Compensation Pursuant to the Omnibus Budget Reconciliation Act of 1993, certain non- performance-based compensation in excess of $1,000,000 to executives of public companies is no longer deductible to these companies. Qualifying performance- based incentive compensation, however, would be both deductible and excluded for purposes of calculating the $1,000,000 compensation threshold. In this regard, the Compensation Committee must determine whether any actions with respect to this new limit should be taken by the Company. The Company's executive compensation for 1999 did not exceed the legal limitations. The Compensation Committee will continue to monitor this situation and will take appropriate action if it is warranted in the future. Compensation Committee: Williams L. Marks, Roy J. Nichols and James L. North. Compensation Committee Interlocks and Insider Participation James L. North, a partner in the law firm of James L. North & Associates, is a director of the Company and as of December 31, 1999, beneficially owned 143,000 shares of the Common Stock of the Company. James L. North & Associates provided legal services to the Company during 1999. All bills for services rendered by James L. North & Associates are reviewed and approved by the Company's Vice President - Finance and Chief Financial Officer. Management believes that the fees for such services are comparable to those charged by other firms for services rendered to the Company. STOCK PERFORMANCE GRAPH The Company's Common Stock began trading on the Nasdaq National Market on August 9, 1994. The price information reflected for the Company's Common Stock in the following performance graph and accompanying table represents the closing sales prices of the Common Stock for the period from December 31, 1994 through December 31, 1999 on an annual basis. The graph and the accompanying table compare the cumulative total stockholders' return on the Company's Common Stock with the Nasdaq Telecommunications Index and the Nasdaq US Index. The calculations in the following graph and table assume that $100 was invested on December 31, 1994 in each of the Company's Common Stock, the Nasdaq Telecommunications Index and the Nasdaq US Index and also assume dividend reinvestment. The closing sale price of the Common Stock on the Nasdaq National Market was $73.375 per share on March 1, 2000. 11 Comparison of Cumulative Total Return Among the Company, Nasdaq Telecommunications Index and Nasdaq US Index [GRAPH APPEARS HERE] ======================================================================================= 12/31/94 12/31/95 12/31/96 12/31/97 12/31/98 12/31/99 ======================================================================================= ADTRAN, Inc. $100 $237 $181 $120 $ 80 $225 ======================================================================================= NASDAQ Telecommunications $100 $131 $134 $196 $322 $561 Index ======================================================================================= NASDAQ US Index $100 $141 $174 $213 $300 $542 ======================================================================================= 12 SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and regulations of the Securities and Exchange Commission thereunder require the Company's directors, officers and persons who own more than 10% of the Company's Common Stock, as well as certain affiliates of such persons, to file initial reports of their ownership of the Company's Common Stock and subsequent reports of changes in such ownership with the Securities and Exchange Commission and the National Association of Securities Dealers, Inc. Directors, officers and persons owning more than 10% of the Company's Common Stock are required by Securities and Exchange Commission regulations to furnish the Company with copies of all Section 16(a) reports they file. Based solely on its review of the copies of such reports received by it, the Company believes that during the fiscal year ended December 31, 1999, its directors, officers and owners of more than 10% of its Common Stock complied with all applicable filing requirements. PROPOSAL 2 - RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS The Board of Directors of the Company, upon the recommendation of the Audit Committee, has appointed the firm of PricewaterhouseCoopers LLP to serve as independent accountants of the Company for the fiscal year ending December 31, 2000, and has directed that such appointment be submitted to the stockholders of the Company for ratification at the Annual Meeting. PricewaterhouseCoopers LLP has served as independent accountants of the Company since 1986 and is considered by management of the Company to be well qualified. If the stockholders do not ratify the appointment of PricewaterhouseCoopers LLP the Board of Directors will reconsider the appointment. Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so. They also will be available to respond to appropriate questions from stockholders. The Board of Directors unanimously recommends that the stockholders vote "FOR" the proposal to ratify the appointment of PricewaterhouseCoopers LLP as independent accountants of the Company. PROPOSAL 3 - RATIFICATION OF PROPOSAL TO AMEND THE 1996 EMPLOYEES INCENTIVE STOCK OPTION PLAN Introduction The Company's 1996 Employees Incentive Stock Option Plan (the "1996 Stock Option Plan") currently permits Incentive Stock Options and Non-Qualified Stock Options to purchase up to an aggregate of 2,488,100 shares of common stock of the Company, subject to adjustment in the event of a recapitalization, merger, stock split or any other change in the corporate structure or shares of stock of the Company, to be granted to key employees (including officers and directors who are also employees) of the Company. The following description of the 1996 Stock Option Plan is qualified in its entirety by reference to the applicable provisions of the 1996 Stock Option Plan and agreements related to the 1996 Stock Option Plan. 13 Proposed Amendment The Board of Directors of the Company has approved, and recommends that the stockholders of the Company approve, an amendment to the 1996 Stock Option Plan to increase the number of shares authorized for issuance under the 1996 Stock Option Plan from 2,488,100 shares to 5,488,100 shares. Stock Subject to Options The stock subject to the options is the Company's authorized but unissued or reacquired Common Stock. On March 1, 2000, the closing price of the Company's Common Stock as reported by the Nasdaq National Market on that day was $73.375 per share. The unexercised portion of shares of Common Stock allocable to expired or terminated options granted under the Plan may again become subject to options under the Plan. Types of Awards Incentive stock options ("ISOs") and nonqualified stock options ("NQSOs") may be granted under the 1996 Stock Option Plan (together, "Options"). Administration The 1996 Stock Option Plan is administered by the Stock Option Plan Committee (the "Committee"), consisting of two or more individuals appointed by the Board of Directors of the Company from among its members. The members of the Committee cannot participate in the 1996 Stock Option Plan and must be "outside directors" within the meaning of Section 162(m)(4)(C)(i) of the Internal Revenue Code of 1986, as amended (the "Code"). The Board from time to time may remove members from, or add members to, the Committee, and shall fill all vacancies on the Committee. The Committee has authority (i) to determine the individuals to whom Options will be granted from among those individuals who are eligible, as well as the terms of Options and the number of shares of Common Stock reserved in connection with such Options, (ii) to determine whether an Option will constitute an ISO intended to qualify under Section 422 of the Code or a NQSO not intended to qualify under Section 422 and (iii) to interpret the provisions of, and prescribe, amend and rescind any rules and regulations relating to, the 1996 Stock Option Plan. Eligibility and Grants of Options Under the terms of the 1996 Stock Option Plan, all employees of the Company (and any parent or subsidiary corporations), including such employees who are also members of the Board (or of the board of directors of a parent or subsidiary corporation) are eligible for consideration for the granting of Options by the Committee. As of December 31, 1999, there were approximately 1,297 employees of the Company and its subsidiaries, all of whom are eligible to participate in the 1996 Stock Option Plan. The Company has no definitive plans to grant stock options to any particular employee at this time. 14 Shares Available The stock subject to the Options and other provisions of the 1996 Stock Option Plan is the authorized but unissued or reacquired shares of Common Stock of the Company. Subject to adjustment in accordance with the terms of the 1996 Stock Option Plan, up to 2,488,100 shares of Common Stock, in the aggregate, may be granted or purchased under the 1996 Stock Option Plan, and the unexercised portion of shares of Common Stock allocable to expired or terminated Options may again become subject to Options under the 1996 Stock Option Plan. On July 15, 1999, the Company granted 612,000 options under the 1996 Stock Option Plan to certain eligible employees, with the exercise of such options being contingent upon the approval by the stockholders of the Company of the increase in the number of shares authorized for issuance under the 1996 Stock Option Plan as described in this Proposal 3. Options Granted As of December 31, 1999, the Company has granted options under the 1996 Stock Option Plan to the named executive officers in the following amounts: Mr. Smith - 0; Mr. Thrailkill - 315,000; Mr. Fredrickson - 135,000; Mr. Harvey - 135,000; and Mr. Stanton - 140,000. Mr. Thrailkill is also the only director who has been granted options under the 1996 Stock Option Plan and the only individual who has been granted more than 5% of the total options granted under the 1996 Stock Option Plan. As of December 31, 1999, the current executive officers, as a group, have been granted a total of 1,341,000 options under the 1996 Stock Option Plan, and all other employees have been granted a total of 1,864,925 options. Of the options granted under the 1996 Stock Option Plan, the exercise of 612,000 options granted on July 15, 1999 is contingent upon the approval by the stockholders of the increase in the number of shares authorized for issuance as described in this Proposal 3. Terms of Options Option Price. The purchase price of the Common Stock underlying each Option granted under the 1996 Stock Option Plan will be the fair market value of the Common Stock on the date the option is granted, unless otherwise determined by the Committee. However, the option price for ISOs may not be less than 100% (110% for options granted to an optionee who owns more than 10% of the total combined voting power of all classes of stock of either the Company or any parent or subsidiary corporation of the Company) of the fair market value of the Common Stock on the date the ISO is granted. Vesting. Options granted under the 1996 Stock Option Plan will become exercisable (i.e., vested) as of the first anniversary of the grant date, unless otherwise provided by the Committee pursuant to a schedule established at the time the Options are granted; provided, if the optionee ceases to be an employee of the Company, the optionee's rights with regard to all non-vested Options cease immediately. Notwithstanding the vesting schedule established by the Committee, all non-vested Options previously granted to an optionee immediately vest upon the optionee's becoming "Disabled" (as defined in the 1996 Stock Option Plan), or upon his or her death or upon a "Change of Control" of the Company (as defined in the 1996 Stock Option Plan). See "Change of Control" below. 15 Term of Options. The term of any Option will be determined by the Committee in accordance with the 1996 Stock Option Plan, but the term may not exceed 10 years from the date of grant (or 5 years in the case of ISOs granted to optionees who own more than 10% of the total combined voting power of all classes of stock of either the Company or any parent or subsidiary corporation). No Option may be granted under the 1996 Stock Option Plan after February 14, 2006. Termination of Employment. Vested Options must be exercised within the earlier of: (i) three months after an employee optionee ceases to be in the employ of the Company or any parent or subsidiary for any reason other than death, disability or for "cause" (as defined in the 1996 Stock Option Plan), unless the employee dies within this three month period; (ii) the expiration date of the option; (iii) immediately upon the removal of the employee for "cause"; (iv) one year after termination of employment with the Company or any parent or subsidiary because of disability, unless the optionee dies within this one year period; or (v) one year after the death of an optionee who dies (a) while in the employ of the Company or any parent or subsidiary, (b) within three months after termination of employment with the Company or any parent or subsidiary for a reason other than for "cause," or (c) within one year after employment with the Company or any parent or subsidiary is terminated due to disability. Notwithstanding the immediately preceding sentence, if an optionee's employment terminates for any reason other than death or disability at any time after a "Change of Control" (as defined under "Change of Control" below), the term of all options of the optionee will be extended through the three month period immediately following such termination of employment. However, the Committee may waive the above expiration periods with respect to any NQSOs granted under the 1996 Stock Option Plan and provide different expiration dates in a NQSO option agreement. Exercise of Options. An Option granted under the 1996 Stock Option Plan may be exercised for less than the full number of shares of Common Stock subject to such Option, provided that no Option may be exercised for less than (i) 100 shares or (ii) the total remaining shares subject to the Option, if less than 100 shares. Upon exercise of an Option, an optionee must pay for the Common Stock subject to the exercise. Payment may be made in cash, in shares of Common Stock (including the retention by the Company of optioned shares of Common Stock with a fair market value equal to the exercise price), or by a combination of the foregoing. Transfers. The 1996 Stock Option Plan does not permit an optionee to sell, assign or otherwise transfer Options except by transfer to a "Beneficiary" at the death of the optionee, and any other purported transfer is null and void. Options are exercisable during the optionee's life only by the optionee (unless the optionee is incapacitated and unable to exercise options). Upon the death of the optionee, Options will be exercisable by the optionee's "Beneficiary." Amendment and Termination The Board of Directors of the Company may amend or terminate the 1996 Stock Option Plan at any time, provided that (i) no amendment may be effected without the consent of the optionees if such amendment would adversely affect in any way the rights of such optionees under the 1996 Stock Option Plan, and (ii) no amendment may be effected without the prior approval of the stockholders of the Company if (A) the amendment would cause the applicable portions of the 1996 Stock Option Plan to fail to qualify as an "incentive stock option plan" pursuant to Section 422 of the Code, (B) the amendment would materially increase the benefits accruing to participants under the 1996 Stock Option Plan, (C) the amendment would materially increase the number of securities which may be issued under the 1996 Stock Option Plan, (D) the 16 amendment would materially modify the requirements as to eligibility for participation in the 1996 Stock Option Plan, or (E) the amendment would modify the material terms of the 1996 Stock Option Plan within the meaning of regulations under Section 162(m) of the Code. The 1996 Stock Option Plan will terminate on the later of (i) the complete exercise or lapse of the last outstanding Option granted under the 1996 Stock Option Plan or (ii) the last date upon which Options may be granted under the 1996 Stock Option Plan, February 14, 2006, subject to its earlier termination by the Board at any time. Change of Control For purposes of the 1996 Stock Option Plan, the term "Change of Control" is defined to mean any one of the following events: (i) the acquisition by a Person (including "affiliates" and "associates" of such Person, but excluding the Company, any "parent" or "subsidiary" of the Company, or any employee benefit plan of the Company or of any "parent" or "subsidiary" of the Company) of a sufficient number of shares of the Common Stock, or securities convertible into the Common Stock, and whether through direct acquisition of shares or by merger, consolidation, share exchange, reclassification of securities or recapitalization of or involving the Company or any "parent" or "subsidiary" of the Company, to constitute the Person the actual or beneficial owner of greater than 50% of the Common Stock; or (ii) any sale, lease, transfer, exchange, mortgage, pledge or other disposition, in one transaction or a series of transactions, of all or substantially all of the assets of the Company or of any "subsidiary" of the Company to a Person described in subsection (a) above. Adjustments In the event of changes in the number or kind of outstanding shares of the Common Stock by reason of a recapitalization, reclassification, stock split, combination of shares or dividend payable in shares of Common Stock, an appropriate and equitable adjustment will be made by the Committee to the number and kind of shares subject to Options granted under the 1996 Stock Option Plan, and to the number and kind of shares remaining available for the granting of Options. Additionally, in the event that the Company is involved in a reorganization involving a merger, consolidation, acquisition of the stock or acquisition of the assets of the Company that does not constitute a Change of Control, the Committee, in its discretion, may declare that (i) outstanding Options apply to the securities of the resulting corporation; (ii) outstanding Options are nonforfeitable and fully exercisable or vested; and/or (iii) outstanding Options are nonforfeitable and fully exercisable or vested and are to be terminated after giving at least 30 days notice to all optionees. If the Board of Directors adopts a plan of dissolution and liquidation that is approved by the stockholders of the Company, all of the rights of all optionees will become immediately nonforfeitable and exercisable through the date of dissolution. 17 Federal Income Tax Consequences The Company intends that part of the 1996 Stock Option Plan qualify as an incentive stock option plan and that any option granted in accordance with such portion of the 1996 Stock Option Plan qualify as an ISO, all within the meaning of Section 422 of the Code. The tax effects of any other stock option granted under the 1996 Stock Option Plan should be determined under Section 83 of the Code. The following is a brief description of the consequences under the Code of the receipt or exercise of Options. ISOs. An option holder has no tax consequences upon issuance or, generally, upon exercise of an ISO. An option holder will recognize income when he sells or exchanges the shares acquired upon exercise of an ISO. This income will be taxed at the applicable capital gains rate if the sale or exchange occurs after the expiration of the requisite holding periods. Generally, the requisite holding periods expire two years after the date of grant of the ISO and one year after the date of acquisition of the Common Stock pursuant to the exercise of the ISO. If an option holder disposes of the Common Stock acquired pursuant to exercise of an ISO before the expiration of the requisite holding periods, the option holder will recognize compensation income in an amount equal to the difference between the option price and the lesser of (i) the fair market value of the shares on the date of exercise and (ii) the price at which the shares are sold. This amount will be taxed at ordinary income rates. If the sale price of the shares is greater than the fair market value on the date of exercise, the difference will be recognized as gain by the option holder and taxed at the applicable capital gains rate. If the sale price of the shares is less than the option price, the option holder will recognize a capital loss equal to the excess of the option price over the sale price. For these purposes, the use of shares acquired upon exercise of an ISO to pay the option price of another option (whether or not it is an ISO) will be considered a disposition of the shares. If this disposition occurs before the expiration of the requisite holding periods, the option holder will have the same tax consequences as are described in the immediately preceding paragraph. If the option holder transfers any such shares after holding them for the requisite holding periods or transfers shares acquired pursuant to exercise of a NQSO or on the open market, he generally will not recognize any income upon the exercise. Whether or not the transferred shares were acquired pursuant to an ISO and regardless of how long the option holder has held such shares, the basis of the new shares received pursuant to the exercise will be computed in two steps. In the first step, a number of new shares equal to the number of older shares tendered (in payment of the option's exercise) is considered exchanged under Section 1036 of the Code and the rulings thereunder; these new shares receive the same holding period and the same basis that the option holder had in the old tendered shares, if any, plus the amount included in income from the deemed sale of the old shares and the amount of cash or other nonstock consideration paid for the new shares, if any. In the second step, the number of new shares received by the option holder in excess of the old tendered shares receives a basis of zero, and the option holder's holding period with respect to such shares commences upon exercise. An option holder may have tax consequences upon exercise of an ISO if the aggregate fair market value of shares of the Common Stock subject to ISOs which first become exercisable by an option holder in any one calendar year exceeds $100,000. If this occurs, the excess shares will be treated as though they are subject to a NQSO instead of an ISO. Upon exercise of an option with respect to these shares, the option holder will have the tax consequences described below with respect to the exercise of NQSOs. 18 Finally, except to the extent that an option holder has recognized income with respect to the exercise of an ISO (as described in the preceding paragraphs), the amount by which the fair market value of a share of the Common Stock at the time of exercise of the ISO exceeds the option price will be included in determining an option holder's alternative minimum taxable income and may cause the option holder to incur an alternative minimum tax liability in the year of exercise. There will be no tax consequences to the Company upon the issuance or, generally, upon the exercise of an ISO. However, to the extent that an option holder recognizes ordinary income upon exercise, as described above, the Company will have a deduction in the same amount. NQSOs. Neither the Company nor the option holder has income tax consequences from the issuance of NQSOs. Generally, in the tax year when an option holder exercises NQSOs, the option holder recognizes ordinary income in the amount by which the fair market value of the shares at the time of exercise exceeds the option price for such shares. The Company will have a deduction in the same amount as the ordinary income recognized by the option holder in the Company's tax year in which or with which the option holder's tax year (of exercise) ends. If an option holder exercises a NQSO by paying the option price with previously acquired shares of Common Stock, the option holder will recognize income (relative to the new shares he is receiving) in two steps. In the first step, a number of new shares equivalent to the number of older shares tendered (in payment of the NQSO exercised) is considered to have been exchanged in accordance with Section 1036 of the Code and the rulings thereunder, and no gain or loss is recognized. In the second step, with respect to the number of new shares acquired in excess of the number of old shares tendered, the option holder will recognize income on those new shares equal to their fair market value less any nonstock consideration tendered. The new shares equal to the number of the older shares tendered will receive the same basis the option holder had in the older shares, and the option holder's holding period with respect to the tendered older shares will apply to those new shares. The excess new shares received will have a basis equal to the amount of income recognized by the option holder by exercise, increased by any nonstock consideration tendered. Their holding period will commence upon the exercise of the option. Limitation on Company Deductions. No federal income tax deduction is allowed for compensation paid to a "covered employee" in any taxable year of the Company beginning on or after January 1, 1994, to the extent that such compensation exceeds $1,000,000. For this purpose, "covered employees" are generally the chief executive officer of the Company and the four highest compensated officers of the Company whose annual salary and bonus exceeds $100,000, and the term "compensation" generally includes amounts includable in gross income as a result of the exercise of stock options or stock appreciation rights, or the receipt of stock options. This deduction limitation does not apply to compensation that is (1) commission-based compensation, (2) performance-based compensation, (3) compensation which would not be includable in an employee's gross income, and (4) compensation payable under a written binding contract in existence on February 17, 1993, and not materially modified thereafter. Currently, the Company does not have any covered employee to which this limitation would apply. Compensation attributable to a stock option will generally satisfy the limitation exception for performance-based compensation if the grant or award is made by a "compensation committee" (a committee composed of "outside" directors), the "material terms" (including which employees are eligible to receive compensation, the maximum number of shares that may be granted to an optionee and the exercise price of 19 the options) of the plan under which the option or right is granted are disclosed to stockholders and approved by a majority of the stockholder vote, the "compensation committee" certifies that performance goals were in fact satisfied before the compensation is paid, and, under the terms of the option or right, the amount of compensation the employee could receive is based solely on an increase in the value of the stock after the date of the grant or award. Stock options granted under the 1996 Stock Option Plan may satisfy these requirements, depending upon the specific terms, provisions, restrictions and limitations of such options or rights. ERISA. The 1996 Stock Option Plan is not, and is not intended to be, an employee benefit plan or qualified retirement plan. The 1996 Stock Option Plan is not, therefore, subject to the Employee Retirement Income Security Act of 1974, as amended, or Section 401(a) of the Code. The Board of Directors unanimously recommends that the stockholders vote "FOR" the proposal to amend the 1996 Employees Incentive Stock Option Plan. STOCKHOLDERS' PROPOSALS FOR 2000 ANNUAL MEETING Proposals of stockholders, including nominations for the Board of Directors, intended to be presented at the 2001 Annual Meeting of Stockholders should be submitted by certified mail, return receipt requested, and must be received by the Company at its executive offices in Huntsville, Alabama, on or before November 8, 2000 to be eligible for inclusion in the Company's proxy statement and form of proxy relating to that meeting and to be introduced for action at the meeting.
