PROXY STATEMENT
FOR THE ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD APRIL 20, 1999
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 1999 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 Tuesday, April 20, 1999, 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 10, 1999.
VOTING
GENERAL
The securities that can be voted at the Annual Meeting consist of Common Stock of the Company, $.01 par value per share, 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, 1999. On the record date, 39,425,098 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 1995 Directors' Stock Option Plan from 70,000 to 200,000 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.
In voting with regard to the proposal to ratify (a) an increase in the initial stock option grant under the 1995 Directors' Stock Option Plan to an incoming director to 10,000 shares of Common Stock of the Company and (b) an increase in the subsequent annual grants to a director from 2,000 to 5,000 shares of Common Stock of the Company (Proposal 4), stockholders may vote in favor of the entire proposal or against the proposal or may abstain from voting. The vote required to approve Proposal 4 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 four proposals to be considered at the Annual Meeting is discretionary.
As of March 1, 1999 (the record date for the Annual Meeting), the directors and executive officers of the Company beneficially owned or controlled approximately 19,834,026 shares of Common Stock of the Company, constituting approximately 50.3% 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 four 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 four proposals on the enclosed proxy card. All properly executed proxy cards delivered by stockholders to the Company in time to be voted
2

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, "FOR" AN INCREASE IN THE AGGREGATE NUMBER OF SHARES OF COMMON STOCK AUTHORIZED FOR ISSUANCE UNDER THE 1995 DIRECTORS' STOCK OPTION PLAN AND "FOR" AN INCREASE IN THE INITIAL OPTION GRANT TO AN INCOMING DIRECTOR AND AN INCREASE IN THE SUBSEQUENT ANNUAL OPTION GRANTS TO A DIRECTOR. 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, 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, 1998, (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 Company believes that each of the named individuals and group has sole voting and investment power with regard to the shares shown except as otherwise noted.

BOARD OF DIRECTORS' REPORT ON EXECUTIVE COMPENSATION
This Report on Executive Compensation of the Board of Directors of the Company discusses the methods that were used to establish executive compensation for the fiscal year ended December 31, 1998. 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 1998, 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 1998 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 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 1998 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. 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. The bonuses disclosed in Table 1 for 1998 include (i) bonuses granted as a result of the acheivement of specified operational targets and (ii) individual performance bonuses granted by the Chief Executive Officer.
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
9

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 1998 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 beneficially owns 141,000 shares of the Common Stock of the Company. The Company paid James L. North & Associates fees of $78,485.00 plus expenses of $1,264.73 for legal services rendered during 1998. 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 August 9, 1994 through December 31, 1998 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 August 9, 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 $19.75 per share on March 1, 1999.

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, 1998, its directors, officers and owners of more than 10% of its Common Stock complied with all applicable filing requirements, except that (i) a delinquent Form 4 filing for Robert A. Fredrickson was disclosed on a year-end Form 5 filing and (ii) two Form 4 reports for Jude T. Panetta were filed after their respective due dates.
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, 1999, 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 stock holders 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.
PROPOSALS 3 AND 4 - RATIFICATION OF PROPOSALS TO AMEND THE
1995 DIRECTORS STOCK OPTION PLAN
INTRODUCTION
The Company's 1995 Directors' Stock Option Plan (the "1995 Directors' Stock Option Plan") currently permits non-qualified stock options to purchase up to an aggregate of 70,000 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 directors who are not employees of the Company or any parent or subsidiary corporation of the Company. The following description of the 1995 Directors' Stock Option Plan is qualified in its entirety by reference to the applicable provisions of the 1995 Directors' Stock Option Plan and agreements related to the 1995 Directors' Stock Option Plan.
12

PROPOSED AMENDMENT
The Board of Directors of the Company has approved, and recommends that the stockholders of the Company approve, an amendment to the 1995 Directors' Stock Option Plan to increase the number of shares authorized for issuance under the 1995 Directors' Stock Option Plan from 70,000 shares to 200,000 shares. The Board of Directors of the Company has also approved, and recommends that the stockholders of the Company approve an amendment to the 1995 Directors' Stock Option Plan (a) to increase the initial option grant to an incoming director to 10,000 shares of Common Stock and (b) to increase the subsequent annual option grant to a director from 2,000 to 5,000 shares of Common Stock.
STOCK SUBJECT TO OPTIONS
The stock subject to the options is the Company's authorized but unissued or reacquired Common Stock. On March 1, 1999, the closing price of the Company's Common Stock as reported by the Nasdaq National Market on that day was $19.75 per share. The unexercised portion of shares of Common Stock allocable to expired or terminated options granted under the 1995 Directors' Stock Option Plan may again become subject to options under the 1995 Directors' Stock Option Plan.
TYPES OF AWARDS
Non-qualified stock options ("Options") may be granted under the 1995 Directors' Stock Option Plan.
ADMINISTRATION
The 1995 Directors' Stock Option Plan is administered by the Board of Directors or by a Directors' 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 Board from time to time may remove members from, or add members to, the Committee, and shall fill all vacancies on the Committee. Presently, the Board of Directors administers the 1995 Directors' Stock Option Plan.
The Board of Directors or the Committee, as the case may be, has authority to interpret the provisions of, and prescribe, amend and rescind any rules and regulations relating to, the 1995 Directors' Stock Option Plan.
ELIGIBILITY AND GRANTS OF OPTIONS
13

Under the terms of the 1995 Directors' Stock Option Plan, all directors who are not employees of the Company or any parent or subsidiary corporation of the Company shall receive a grant of Options as set forth in the 1995 Directors' Stock Option Plan. As of December 31, 1998, there were three non-employee directors of the Company. Presently, under the 1995 Directors' Stock Option Plan, upon initially becoming a director of the Company, an individual will receive a grant of an Option to purchase 5,000 shares of Common Stock of the Company. In addition, as of December 31 of each calendar year following the calendar year in which the director begins his service as a director of the Company, the director will receive an additional grant of an Option to purchase 2,000 shares of Common Stock of the Company, provided that such director is still serving as a director of the Company on such date. Under the 1995 Directors' Stock Option Plan as it is proposed to be amended, upon initially becoming a director of the Company, an individual will receive a grant of an Option to purchase 10,000 shares of Common Stock of the Company. In addition, as of December 31 of each calendar year following the calendar year in which the director begins his service as a director of the Company, the director will receive an additional grant of an Option to purchase 5,000 shares of Common Stock of the Company, provided that such director is still serving as a director of the Company on such date.
SHARES AVAILABLE
The stock subject to the Options and other provisions of the 1995 Directors' 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 1995 Directors' Stock Option Plan, up to 70,000 shares of Common Stock, in the aggregate, may be granted or purchased under the 1995 Directors' 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 1995 Directors' Stock Option Plan. As of December 31, 1998, there were only 28,000 shares of Common Stock available for grant under the 1995 Directors' Stock Option Plan; after the amendment, there would be 158,000 shares available for grant under the 1995 Directors' Stock Option Plan.
TERMS OF OPTIONS
OPTION PRICE. The purchase price of the Common Stock underlying each Option granted under the 1995 Directors' Stock Option Plan will be the fair market value of the Common Stock on the date the option is granted.
VESTING. Options granted under the 1995 Directors' Stock Option Plan will become exercisable (i.e., vested) as of the first anniversary of the grant date; provided, if the optionee ceases to be a director of the Company, the optionee's rights with regard to all non-vested Options cease immediately. Notwithstanding the foregoing, all non-vested Options previously granted to an optionee immediately vest upon the optionee becoming "Disabled" (as defined in the 1995 Directors' Stock Option Plan), or upon his death or upon a "Change of Control" of the Company (as defined in the 1995 Directors' Stock Option Plan). See "Change of Control" below.
TERM AND EXERCISE OF OPTIONS. The term of any Option shall commence on the date of grant and shall expire ten years from the date the Option is granted. An Option granted under the 1995 Directors' 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
14

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 1995 Directors' 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."
TERMINATION OF SERVICE AS A DIRECTOR. Vested Options must be exercised within the earlier of: (i) three months after an optionee ceases to be a director of the Company or any parent or subsidiary for any reason other than death or disability (unless the director dies within this three month period) or for "cause" (as defined in the 1995 Directors' Stock Option Plan); (ii) the expiration date of the option; (iii) immediately upon the removal of the director for "cause"; (iv) one year after termination of service as a director of the Company or a 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 serving as a director of the Company or a parent or subsidiary, (b) within three months after service as a director is terminated by the Company or a parent or subsidiary, or (c) within one year after service as a director of the Company or a parent or subsidiary is terminated due to disability.
AMENDMENT AND TERMINATION
The Board of Directors of the Company may amend or terminate the 1995 Directors' Stock Option Plan at any time, provided that (i) no amendment may be effected without the consent of the optionees if such amendment would affect in any way the rights of such optionees under the 1995 Directors' 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 1995 Directors' Stock Option Plan to fail to qualify as an "incentive stock option plan" pursuant to Section 422 of the Internal Revenue Code of 1996, amended (the "Code"), (B) the amendment would materially increase the benefits accruing to participants under the 1995 Directors' Stock Option Plan, (C) the amendment would materially increase the number of securities which may be issued under the 1995 Directors' Stock Option Plan or (D) the amendment would materially modify the requirements as to eligibility for participation in the 1995 Directors' Stock Option Plan.
The 1995 Directors' Stock Option Plan will terminate on the later of (i) the complete exercise or lapse of the last outstanding Option granted under the 1995 Directors' Stock Option Plan or (ii) the last date upon which Options may be granted under the 1995 Directors' Stock Option Plan, subject to its earlier termination by the Board at any time.
CHANGE OF CONTROL
For purposes of the 1995 Directors' 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
15

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, but only if such acquisition occurs without approval or ratification by a majority of the members of the Board prior to such acquisition; 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 "parent" or "subsidiary" of the Company to a Person described in subsection (a) above, but only if such transaction occurs without approval or ratification by a majority of the members of the Board.
ADJUSTMENTS
In the event of changes in the number 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 1995 Directors' 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 non- forfeitable and fully exercisable or vested; and/or (iii) outstanding Options are non-forfeitable and fully exercisable or vested and are to be terminated after giving at least 30 days notice to all optionees. If the Company is dissolved, all of the rights of all optionees will become immediately non- forfeitable and exercisable through the date of dissolution.
FEDERAL INCOME TAX CONSEQUENCES
The tax effects of any options granted under the 1995 Directors' 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.
NON-QUALIFIED STOCK OPTIONS. Neither the Company nor the option holder has income tax consequences from the issuance of non-qualified stock options ("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
16

recognize income on those new shares equal to their fair market value less any non-stock 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 non-stock consideration tendered. Their holding period will commence upon the exercise of the option.
ERISA. The 1995 Directors' Stock Option Plan is not, and is not intended to be, an employee benefit plan or qualified retirement plan. The 1995 Directors' 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 STOCKHOLDERS VOTE "FOR"
THE PROPOSALS TO AMEND THE 1995 DIRECTORS' 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 2000 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 11, 1999 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. Any stockholder proposal must be in writing and must set forth (i) a description of the business desired to be brought before the meeting and the reasons for conducting the business at the meeting, (ii) the name and address, as they appear on the Company's books, of the stockholder submitting the proposal, (iii) the class and number of shares that are beneficially owned by such stockholder, (iv) the dates on which the stockholder acquired the shares, (v) documentary support for any claim of beneficial ownership, (vi) any material interest of the stockholder in the proposal, (vii) a statement in support of the proposal and (viii) any other information required by the rules and regulations of the Securities and Exchange Commission.
OTHER MATTERS THAT MAY COME BEFORE THE ANNUAL MEETING
The Board of Directors of the Company knows of no matters other than those referred to in the accompanying Notice of Annual Meeting of Stockholders which may properly come before the Annual Meeting. However, if any other matter should be properly presented for consideration and voting at the Annual Meeting or any adjournments thereof, it is the intention of the persons named as proxies on the enclosed form of proxy card to vote the shares represented by all valid proxy cards in accordance with their judgment of what is in the best interest of the Company.

Re: ADTRAN, Inc. (Commission File No. 0000926282) Definitive Proxy Materials pursuant to SEC Rule 14a-6(b)
Ladies and Gentlemen:
On behalf of our client, ADTRAN, Inc. (the "Company"), we submit herewith for filing with the Commission by EDGAR one definitive copy of the Company's revised Proxy Statement and form of proxy card relating to the Company's 1999 Annual Meeting of Stockholders to be held on April 20, 1999. This amendment is being filed to correct a printing error in the Summary Compensation Table on Page 8 of the Proxy Statement. When the Proxy Statement was converted to an EDGAR format, the printer dropped a number from the compensation description for Steven L. Harvey. This amendment is being filed to correct the printer's mistake. Please note, however, that the table was printed correctly in the Proxy Statement that was delivered to shareholders on March 11, 1999.
Very truly yours,

/s/ Thomas P. Lauth III
