To elect six directors to serve for the ensuing year. The names of the nominees intended to be presented for election are: Robert V. Adams, Jean-Claude Asscher, Daniel L. Brenner, Michael L. Margolis, Howard Oringer and Jon F. Rager. 2. To approve an amendment to the Company's 1994 Stock Option Plan to increase the number of shares of Common Stock authorized for issuance thereunder from 14,000,000 to 19,000,000. 3. To ratify the appointment of PricewaterhouseCoopers LLP as the Company's independent accountants for the year ending December 31, 1999. 4. To transact such other business as may properly come before the Annual Meeting or any adjournment(s) thereof. Only record holders of Common Stock at the close of business on March 23, 1999 are entitled to notice of, and to vote at, the Annual Meeting and at any adjournment(s) thereof. All shareholders are cordially invited to attend the Annual Meeting in person. Whether or not you expect to attend the Annual Meeting in person, in order to ensure your representation at the Annual Meeting, please mark, sign, date and return the enclosed proxy card as promptly as possible in the postage-prepaid envelope enclosed for that purpose. Any shareholder of record attending the Annual Meeting may vote in person even if such shareholder has returned a proxy. By Order of the Board of Directors Ronald W. Buckly Secretary Calabasas, California April 2, 1999 3 TEKELEC PROXY STATEMENT INFORMATION CONCERNING SOLICITATION AND VOTING GENERAL The enclosed proxy is solicited by and on behalf of the Board of Directors of Tekelec ("Tekelec" or the "Company") for use at the Annual Meeting of Shareholders (the "Annual Meeting") to be held Friday, May 14, 1999, at 9:00 a.m., California time, or at any adjournment(s) thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting of Shareholders (the "Notice"). The Annual Meeting will be held at the Company's offices located at 26580 West Agoura Road, Calabasas, California 91302. These proxy solicitation materials were first mailed on or about April 5, 1999 to all shareholders entitled to vote at the Annual Meeting. Only shareholders of record at the close of business on March 23, 1999 (the "Record Date") are entitled to notice of, and to vote at, the Annual Meeting. At the Record Date, 54,594,592 shares of the Company's Common Stock were issued and outstanding. Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before its use by delivering to the Secretary of the Company a written notice of revocation or a duly executed proxy bearing a later date or by attending the Annual Meeting and voting in person. VOTING AND SOLICITATION Every shareholder voting in the election of directors may cumulate such shareholder's votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which such shareholder's shares are entitled (one vote per share of Common Stock), or distribute such votes on the same principle among as many candidates as the shareholder chooses, provided that votes cannot be cast for more than six candidates. However, no shareholder may cumulate votes unless the name of the candidate or candidates for whom such votes would be cast has been placed in nomination prior to the voting and any shareholder has given notice, at the Annual Meeting prior to the voting, of such shareholder's intention to cumulate votes. The six candidates receiving the highest number of votes will be elected. On all other matters, each share of Common Stock has one vote. Except as otherwise required by law or the Company's Articles of Incorporation, the affirmative vote of a majority of shares represented and voting at the Meeting (which shares voting affirmatively must also constitute at least a majority of the required quorum) is required for the approval of such other matters. Abstentions are included in the determination of the number of shares present and entitled to vote for purposes of determining the presence of a quorum. Abstentions, however, do not constitute a vote "for" or "against" any matter and thus will be disregarded in the calculation of a plurality or of "votes cast." Shares represented by "broker non-votes" (i.e., shares held by brokers or nominees that are represented at a meeting but with respect to which the brokers or nominees are not empowered to vote on a particular proposal) will also be counted for purposes of determining the presence of a quorum at the Annual Meeting, but will not be treated as shares present and entitled to vote with respect to that matter (even though such shares are considered present and entitled to vote for quorum purposes and may be entitled to vote on other matters). -1- 4 The cost of this solicitation will be borne by the Company. The Company has retained the services of Corporate Investor Communications, Inc. to assist in distributing proxy materials to brokerage houses, banks, custodians and other nominee holders. The estimated cost of such services is $1,000 plus out-of-pocket expenses. Although there are no formal agreements to do so, the Company may reimburse brokerage houses and other persons representing beneficial owners of shares for their expenses in forwarding proxy materials to such beneficial owners. Proxies may be solicited personally or by telephone or telegram by certain of the Company's directors, officers and regular employees, without additional compensation. DEADLINE FOR RECEIPT OF SHAREHOLDER PROPOSALS Proposals of shareholders of the Company which are intended to be presented by such shareholders at the Company's annual meeting of shareholders to be held in 2000 (the "2000 Annual Meeting") must be received by the Company no later than December 6, 1999 in order that they may be included in the proxy statement and form of proxy relating to that annual meeting. In addition, proxies solicited by management may confer discretionary authority to vote on matters which are not included in the proxy statement but which are raised at the 2000 Annual Meeting, unless the Company receives written notice of such matters on or before February 15, 2000; provided, however, that if the date of the 2000 Annual Meeting is more than 30 days before or after the anniversary date of the 1999 Annual Meeting, the Company must receive written notice of such matters within a reasonable time before the Company begins to print and mail its proxy materials. It is recommended that shareholders submitting proposals direct them to the Secretary of the Company via certified mail, return receipt requested, in order to ensure timely delivery. No such proposals were received with respect to the Annual Meeting scheduled for May 14, 1999. PROPOSAL 1 - ELECTION OF DIRECTORS NOMINEES A board of six directors will be elected at the Annual Meeting. Unless otherwise instructed, proxy holders will vote the proxies received by them for the Company's six nominees named below, all of whom are currently directors of the Company. In the event that any nominee of the Company is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who is designated by the present Board of Directors to fill the vacancy. In the event that additional persons are nominated for election as directors, the proxy holders intend to vote all proxies received by them in such a manner in accordance with cumulative voting as will assure the election of as many of the nominees listed below as possible, and, in such event, the specific nominees to be voted for will be determined by the proxy holders. It is not expected that any nominee will be unable or will decline to serve as a director. The term of office of each person elected as a director will continue until the next annual meeting of shareholders and such time as his successor is duly elected and qualified or until his earlier resignation, removal or death. The names of the nominees, and certain information about them, are set forth below: NAME AGE POSITION(S) WITH THE COMPANY DIRECTOR SINCE - ---- --- -------------------------------------------- -------------- Jean-Claude Asscher 70 Chairman of the Board 1972 Robert V.

Since 1976, Mr. Rager has been a practicing accountant with, and President of, Rager Bell Doskocil & Meyer CPAs (and its predecessors). There is no family relationship between any director or executive officer of the Company and any other director or executive officer of the Company except that Mr. Brenner and the spouse of Ronald W. Buckly, the Company's Vice President and General Counsel, are first cousins. INFORMATION REGARDING THE BOARD OF DIRECTORS AND ITS COMMITTEES The Board of Directors held a total of 14 meetings during 1998 and acted twice by unanimous written consent. During 1998, each director of the Company attended at least 75% of the aggregate of the total number of meetings of the Board of Directors held and the total number of meetings held by the Board committees on which he served. The Audit Committee, which during 1998 was comprised of Messrs. Adams, Brenner, Oringer and Rager, met three times during 1998. The Audit Committee recommends the engagement of independent auditors, reviews accounting policies, internal accounting controls and results of audit engagements and generally performs functions related to the financial condition and policies of the Company. The Compensation Committee, which during 1998 was comprised of Messrs. Adams, -3- 6 Brenner, Oringer and Rager, met 11 times during 1998 and acted three times by unanimous written consent. The Compensation Committee is responsible for administering the Company's stock option plans, including determining the persons to whom options are granted and the terms of such options, and the Company's Employee Stock Purchase Plan. The Compensation Committee also advises and makes recommendations to the Company's Board of Directors regarding the compensation of the Company's executive officers. The Company does not have a nominating committee or any committee performing the function thereof. COMPENSATION OF DIRECTORS The Company currently pays each non-employee director a quarterly retainer of $4,000 (except the Chairman of the Board who is paid $6,500), plus $2,000 for attending in person or telephonically a Board of Directors' meeting in excess of four hours and $1,000 for attending in person or telephonically a Board of Directors' meeting of four hours or less. In addition, each member of the Compensation Committee receives $1,000 per quarter (except the Committee's Chairman who is paid $1,750) and $250 for attending a Compensation Committee meeting in person or telephonically. Each member of the Audit Committee receives $1,500 per quarter (except the Committee's Chairman who is paid $2,500) and $500 for attending an Audit Committee meeting in person or telephonically. The total amount of cash compensation paid to non-employee directors for 1998 was approximately $245,000. The Company also reimburses all directors for reasonable expenses incurred in connection with attending Board and Committee meetings. Directors who are not employees of the Company are ineligible to participate in the Company's 1994 Stock Option Plan and Employee Stock Purchase Plan. Under the Company's Non-Employee Director Equity Incentive Plan (the "Director Plan"), each non-employee director automatically receives an option to purchase 120,000 shares of the Company's Common Stock every three years, subject to there being sufficient shares available for issuance under such plan. If the total number of shares to be granted on a specific grant date exceeds the number of shares then available under the Director Plan, the shares remaining available for grant are to be allocated pro rata among the non-employee directors. Each non-employee director elected at the Annual Meeting in 1999 will receive an option to purchase 50,401 shares of the Company's Common Stock (based on the 252,008 shares of Common Stock remaining available for grant under the Director Plan and assuming that all five non-employee directors standing for election at such meeting are elected). Such options will have an exercise price equal to the fair market value of the Common Stock on the date of grant, vest in 12 equal quarterly installments over three years as long as the holder remains a non-employee director of the Company, and terminate upon the earlier of May 14, 2006 or seven months after the director ceases to serve as a non-employee director of the Company. In July 1997, the Company granted to each of Robert Adams, Jean-Claude Asscher, Daniel Brenner, Howard Oringer and Jon Rager, all of whom are non-employee directors of the Company, ten-year warrants to purchase 60,000 shares of the Company's Common Stock at an exercise price of $14.08 per share (i.e., the closing sales price of the Company's Common Stock on The Nasdaq Stock Market on the date of grant). Such warrants vest in 12 equal quarterly installments over three years as long as the holder remains a director of the Company. In January 1998, the Company awarded to each of Messrs. Adams, Asscher, Brenner, Oringer and Rager 3,000 shares of the Company's Common Stock as additional compensation and principally in recognition of services rendered to the Company in connection with the Company's search for a chief executive officer to succeed Allan Toomer. The fair market value of each director's stock award on the award date was approximately $48,000 based on the closing sales price of the Company's Common Stock on The Nasdaq Stock Market on such date. All such stock awards vested on the one-year anniversary of the award date. -4- 7 COMMON STOCK OWNERSHIP OF PRINCIPAL SHAREHOLDERS AND MANAGEMENT The following table sets forth certain information regarding beneficial ownership of the Company's Common Stock as of March 1, 1999 by (i) each person who is known to own beneficially more than 5% of the outstanding shares of the Company's Common Stock, (ii) each of the Company's directors, (iii) each of the executive officers named in the Summary Compensation Table on page 9 and (iv) all current directors and executive officers of the Company as a group: NAME OF BENEFICIAL OWNER(1) SHARES BENEFICIALLY OWNED PERCENT OF CLASS - ------------------------ ------------------------- ---------------- Jean-Claude Asscher 12,712,146(2)(3) 23.3% Tekelec-Airtronic, S.A. 5, rue Carle Vernet 92315 Sevres Cedex, France Edouard Givel 10,465,256(4) 19.2 Natinco, S.A. 8C, avenue de Champel 1206 Geneva, Switzerland Franklin Resources, Inc. 3,375,208(5) 6.2 777 Mariners Island Boulevard San Mateo, CA 94404 Putnam Investments, Inc. 2,729,930(6) 5.0 One Post Office Square Boston, MA 02109 Daniel L.

Mr. Asscher has from time to time acted as the advisor to Mr. Givel with respect to his investment in the Company.

(2) In 1998, the Company granted options to employees to purchase an aggregate of 2,298,500 shares. (3) The exercise price per share of all such options was not less than 100% of the reported closing sales price of the Company's Common Stock on The Nasdaq Stock Market on the date of grant. (4) The Grant Date Present Value is equal to the grant date option value calculated using a modified Black-Scholes American Options Pricing Model (the "Black-Scholes Model"), adjusted to reflect the risk that the options may be forfeited prior to exercise. Black-Scholes Model input assumptions included: (a) an expected time to exercise of five years for officers (such periods are equal to the full vesting terms of the options); (b) an interest rate equal to the interest rate on U.S. government debt instruments with maturities approximately equal to the options' expected time to exercise; (c) volatility equal to the standard deviation of the Company's Common Stock, calculated using daily closing stock prices for the period from January 1994 to December 1998; and (d) an expected dividend yield of 0%. The risk of forfeiture was calculated by applying the annualized weighted-average occurrence of cancellation of the Company's options prior to exercise for the period during 1994-1998 (12.87%) compounded over the expected years to exercise of five years for officers. There can be no assurance that the value realized by an optionee will be at or near the value estimated by the Black-Scholes Model. -9- 12 AGGREGATED OPTION EXERCISES IN 1998 AND OPTION VALUES AT DECEMBER 31, 1998 The following table sets forth certain information concerning stock option exercises during 1998 and unexercised options held as of December 31, 1998 by the executive officers named in the Summary Compensation Table: NUMBER OF SECURITIES VALUE OF SHARES UNDERLYING UNEXERCISED UNEXERCISED IN-THE-MONEY ACQUIRED OPTIONS AT 12/31/98 OPTIONS AT 12/31/98($)(2) ON VALUE -------------------------- --------------------------- NAME EXERCISE(#) REALIZED($)(1) EXERCISABLE UNEXERCISABLE EXERCISABLE UNEXERCISABLE ---- ----------- ------------- ----------- ------------- ----------- ------------- Michael L.

EMPLOYMENT AGREEMENTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL ARRANGEMENTS In 1993, the Company implemented an officer severance plan (the "Severance Plan") pursuant to which executive officers of the Company are entitled to receive certain severance benefits following termination of employment, if such termination is non-temporary, involuntary and without cause. In addition, if there is a "change in control" of the Company, an officer will receive benefits under the Severance Plan if such officer terminates his or her employment with the Company either for any reason within one year following the change in control or for "good reason" (which includes the assignment to the officer of duties significantly inconsistent with his or her prior position or a reduction in his or her compensation or benefits) within two years following such change in control. In March 1999, the Board of Directors amended the Severance Plan to provide that, in addition to the other benefits that an executive officer may be entitled to receive upon termination of his or her employment in connection with or following a change in control, an officer's stock options will vest to the extent then unvested and will be exercisable for one year following the termination of such officer's employment with the Company or a surviving corporation, as the case may be, if, in connection with a change in control (or within two years thereafter with respect to (ii) and (iii) below), such officer (i) is not offered employment by the surviving corporation on terms and conditions generally no less favorable to such officer than the terms and conditions of his or her employment with the Company in effect immediately prior to the change in control; (ii) is terminated without cause by the Company or the surviving corporation; or (iii) terminates for good reason his or her employment with the Company or the surviving corporation. Each eligible officer is entitled to severance pay based on his or her highest annual compensation (i.e., base salary plus bonus), the number of years employed by the Company and the highest office attained prior to termination. Based on such factors, the amounts that would be payable under the Severance Plan to Messrs. Margolis, Godin and Frankie if their employment were terminated as of April 1, 1999 and they were eligible for severance benefits under the -10- 13 Severance Plan would be $364,500, $388,500 and $174,675, respectively. Mr. Werner terminated his employment with the Company in February 1999 and is entitled to receive payments aggregating $192,750 under the Severance Plan. Severance benefits also include continuation, at the Company's expense, of health care insurance and term life insurance for a period of 18 months following termination of employment. In accordance with the terms of an agreement entered into between Allan Toomer and the Company in March 1997, the Company paid to Mr. Toomer in March 1998, in lieu of any benefits which might otherwise be payable to him under the Severance Plan, the sum of $400,000 upon the termination of his employment with the Company. In connection with the commencement of Mr. Margolis' employment with the Company in February 1998, Mr. Margolis entered into an agreement with the Company pursuant to which the Company agreed to pay him an annual base salary of $300,000 and a minimum bonus of $105,000 for 1998, awarded him 30,000 restricted shares of the Company's Common Stock (the "Restricted Shares") and granted to him stock options to purchase 370,000 shares of Common Stock. The Restricted Shares vest in five equal annual installments commencing in February 1999 and the stock options vest over five years commencing in February 1999 provided that Mr. Margolis is an employee of the Company on the vesting dates. In the event Mr. Margolis' employment with the Company terminates under circumstances entitling him to benefits under the Severance Plan, then all unvested installments of the Restricted Shares and the stock options will vest in full upon such termination. As of March 1, 1999, 24,000 Restricted Shares and options covering 296,000 shares were unvested. In addition, the Company reimbursed Mr. Margolis for certain relocation expenses in the amount of approximately $105,000. In accordance with the terms of an agreement entered into between Mr. Suzuki and the Company in May 1998, Mr. Suzuki resigned as an officer of Tekelec and as President of Tekelec, Ltd., Tekelec's Japanese subsidiary, effective December 31, 1998, and presently serves as advisor to the President and a director of Tekelec, Ltd. In consideration for Mr. Suzuki waiving all benefits that he otherwise would be entitled to receive under the Severance Plan, the Company agreed that if Tekelec, Ltd. meets certain performance goals established for 1998, 1999 and 2000, then Tekelec, Ltd. will pay to Mr. Suzuki as incentive compensation the amounts of (Y)20,000,000, (Y)10,000,000 and (Y)10,000,000, respectively (which amounts are equal to approximately $166,900, $83,450 and $83,450 based on the exchange rate in effect as of March 1, 1999). Such amounts will be payable upon the earlier of (i) 60 days following any termination of Mr. Suzuki's employment with Tekelec, Ltd. or (ii) March 1, 2001. Tekelec, Ltd. met the performance goals for 1998. The Company also agreed that if at any time prior to January 1, 2001 Mr. Suzuki's employment is terminated by the Company without "cause" (as such term is defined in the Severance Plan), the Company will pay to Mr. Suzuki (Y)40,000,000 (which amount is equal to approximately $333,800 based on the exchange rate in effect as of March 1, 1999) less the amount of any incentive compensation earned by him under the agreement for any calendar year prior to termination. TEKELEC, LTD. RETIREMENT PLAN In 1990, Tekelec, Ltd. adopted Retirement Pension Rules (the "Plan") to provide retirement benefits to its employees, other than directors and certain other specified categories of employees, who have completed at least three years of service. Effective January 1994, the Plan was amended to provide retirement benefits to directors as well as to employees. The benefit payable under the Plan to a director is based on years of eligible service and a director's highest monthly compensation during his or her service as a director. A director who retires either voluntarily or at the request of Tekelec, Ltd. other than at retirement age with at least three years of eligible service is entitled to receive one lump sum payment -11- 14 equal to a multiple (ranging from one to three for a director with three years of eligible service to 47 for a director with 40 years of eligible service) of his or her highest monthly compensation. If a director of Tekelec, Ltd. retires at retirement age after at least 20 years of eligible service, in lieu of the lump sum payment described above, he or she will receive a retirement benefit payable over ten years or, under certain circumstances, in one lump sum payment equal to the present value of future amounts otherwise payable. Such retirement benefit ranges from a monthly amount of 26% (for a director with 20 years of eligible service) to 51% (for a director with 40 or more years of eligible service) of a director's highest monthly salary. If a director dies before receiving all or any part of the benefit to which he or she would be entitled under the Plan, such benefit would be paid to his or her surviving spouse. Mr. Suzuki is one of two current directors participating in the Plan. As of April 1, 1999, Mr. Suzuki was credited with 13 years of eligible service under the Plan and would be entitled to receive lump sum payments of approximately $220,736 if he were to voluntarily terminate his employment with Tekelec, Ltd. and $367,894 if his employment were to be terminated by Tekelec, Ltd. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During 1998, the Compensation Committee consisted of Messrs. Adams, Brenner, Oringer and Rager, all of whom are non-employee directors. No member of the Compensation Committee is or was a current or former officer or an employee of the Company or any of its subsidiaries other than Mr. Rager who served as the Company's Treasurer from October 1975 to June 1985 and as its Secretary from October 1975 to December 1985. BOARD OF DIRECTORS AND COMPENSATION COMMITTEE REPORTS ON EXECUTIVE COMPENSATION The Board of Directors and the Compensation Committee of the Board of Directors share responsibility for determining and administering the compensation program for the Company's executive officers. The Company's executive compensation program consists of both cash-based and stock-based compensation. The Board of Directors is responsible for determining the annual base salaries of the Company's executive officers and approving the terms of the officer bonus plan, in each case taking into consideration recommendations of the Compensation Committee, and the award of any discretionary bonuses. The Board has delegated to the Compensation Committee the responsibility of recommending to the Board for its approval salaries for the Company's executive officers and the officer bonus plan and administering the Company's stock option plans pursuant to which stock options are granted to key employees. The reports on executive compensation by the Board of Directors and the Compensation Committee and the Performance Graph on page 15 shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933 or under the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such Acts. BOARD OF DIRECTORS REPORT ON EXECUTIVE COMPENSATION The principal objectives of the Company's executive compensation program are to attract, motivate and retain qualified, experienced individuals to serve as officers of the Company and to provide incentives to attain the financial and strategic objectives of the Company. The Company's executive -12- 15 compensation program consists of three basic components -- annual base salaries, cash bonuses and stock options. Based on recommendations of the Compensation Committee, the Board of Directors sets and approves the annual base salaries of all executive officers. Annual salaries are based on consideration of a number of factors, including an officer's responsibilities, experience and qualifications, an evaluation of such officer's past performance and contributions to the Company, information (e.g., compensation surveys) concerning competitive compensation and the Company's financial results and condition. For calendar year 1998, the Board increased the annual base salaries of the Company's executive officers who had been executive officers in 1997 by 0% to 16.2% over 1997 levels. The Board believes that a significant portion of each officer's annual compensation should be related to the Company's financial performance. Accordingly, under the terms of the 1998 Officer Bonus Plan recommended by the Compensation Committee and approved by the Board, each executive officer was eligible to receive a cash bonus equal to a percentage of his annual base salary if the Company achieved certain pre-established financial performance goals. Bonuses under such Plan would only be paid if the Company's revenues and operating income met or exceeded a threshold 100% of both the revenue goal and the operating income goal set forth in the Company's business plan. Based on the Company's financial results in 1998, bonuses in the aggregate amount of $392,000 were earned by the Company's executive officers under the Officer Bonus Plan. Individual bonuses ranged from 12.5% to 38.9% of an officer's base salary. The Board was also responsible for determining the terms and conditions of Mr. Margolis' employment with the Company. In determining Mr. Margolis' annual base salary of $300,000 for 1998, the Board took into consideration essentially the same factors that were considered in setting the annual base salaries of the Company's other executive officers. Under the terms of the 1998 Officer Bonus Plan, Mr. Margolis was eligible to receive a cash bonus equal to a percentage (up to a maximum of 70%) of his annual base salary payable if the Company achieved certain revenue and operating income goals set forth in the Company's business plan. For 1998, the Company guaranteed Mr. Margolis a minimum bonus of $105,000. For services rendered to the Company in 1998, Mr. Margolis' cash compensation consisted of base salary in the amount of $258,462 (Mr. Margolis commenced his employment on February 17, 1998) and a bonus of $105,000. In addition, the Board granted to Mr. Margolis a stock award of 30,000 shares of the Company's Common Stock, which shares vest in five equal annual installments commencing in February 1999 as long as Mr. Margolis remains an employee of the Company. Under Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), a publicly held corporation such as the Company will generally not be allowed a federal income tax deduction for otherwise deductible compensation paid to the executive officers named in the Summary Compensation Table to the extent that compensation (including stock-based compensation) paid to a particular officer exceeds $1 million in any fiscal year. Qualifying performance-based compensation (including compensation attributable to the exercise of stock options) will not be subject to the deductibility limitation if certain conditions are met. Based upon the Company's current compensation plans and policies and the regulations under Section 162(m), it appears unlikely that the compensation to be paid to any of the Company's executive officers for 1999 would exceed the $1 million limitation per officer. BOARD OF DIRECTORS Jean-Claude Asscher, Chairman Robert V. Adams Daniel L. Brenner Michael L. Margolis Howard Oringer Jon F. Rager -13- 16 COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee is responsible for administering the Company's employee stock option plans. Options to purchase the Company's Common Stock are a key component of the Company's executive compensation program. The Compensation Committee views the grant of stock options as a valuable incentive to attract and retain key employees and to motivate them to maximize shareholder value. The Compensation Committee reviews and considers recommendations by the Company's Chief Executive Officer with regard to the grant of stock options to executive officers (other than the Chief Executive Officer) and other key employees whose contributions and skills are important to the long-term success of the Company. Each officer typically receives a stock option grant upon first joining the Company and thereafter is eligible periodically to receive additional stock options. In determining the size and other terms of an option grant to an executive officer, the Compensation Committee considers a number of factors, including such officer's position and responsibilities, individual job performance, salary, previous stock option grants (if any) and length of service to the Company. The exercise price of options is not less than the market price of the Company's Common Stock on the date of grant. Options generally vest over five years, typically in 20 equal quarterly installments following the date of grant, as long as the optionee remains an employee of the Company and, therefore, encourage an optionee to remain an employee of the Company. In connection with the commencement of his employment with the Company, the Compensation Committee granted to Mr. Margolis options to purchase 370,000 shares of the Company's Common Stock at an exercise price equal to the market price of the Company's Common Stock on the date of grant (i.e., $20.22 per share). The options vested as to 74,000 shares in February 1999 on the one-year anniversary of Mr. Margolis' commencement of his employment with the Company, and the remaining 296,000 shares vest and become exercisable in 16 equal quarterly installments over four years provided Mr. Margolis remains an employee of the Company. In 1998, options to purchase an aggregate of 703,000 shares of Common Stock were granted to all executive officers as a group (including options to purchase an aggregate of 550,000 shares granted to Mr. Margolis and an executive officer upon joining the Company) and represented 30.6% of all options granted in 1998. Information concerning options granted during 1998 to the executive officers named in the Summary Compensation Table is provided in the table entitled "Executive Compensation and Other Information - Option Grants in 1998." COMPENSATION COMMITTEE Daniel L. Brenner, Chairman Robert V. Adams Howard Oringer Jon F. Rager CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS The following are certain transactions entered into between the Company and its officers, directors and principal shareholders and their affiliates since January 1, 1998: The Company sells products to Tekelec-Airtronic and its wholly owned subsidiaries which serve as distributors of the Company's products in Europe. During 1998, the aggregate sales of the Company's products to Tekelec-Airtronic and its subsidiaries were approximately $4,269,000. As of December 31, 1998, Tekelec-Airtronic and its subsidiaries owed the Company approximately $1,896,000 for purchases of the Company's products, of which approximately $1,518,000 was owed as of March 1, 1999. -14- 17 PERFORMANCE GRAPH The following graph compares the cumulative total return on the Company's Common Stock with the cumulative total return of the Total Return Index for The Nasdaq Stock Market (U.S. Companies) and the Nasdaq Computer Manufacturers Index for the five-year period commencing January 1, 1994.

The 1994 Plan was amended in 1995, 1996, 1997 and 1998 to increase the number of shares authorized for issuance thereunder by an aggregate of 10,800,000 shares. In March 1999, the Board of Directors further amended the 1994 Plan, subject to shareholder approval, to increase the number of shares authorized for issuance thereunder by 5,000,000 shares. The Board of Directors approved such increase in order to ensure the availability of sufficient shares of the Company's Common Stock for option grants to new employees of the Company, annual performance stock option grants in the first quarter of 2000 and periodic incentive option grants to the Company's employees. If such amendment is approved, a total of 19,000,000 shares will have been authorized for issuance under the 1994 Plan. The Board of Directors believes that such authorized shares should be sufficient to meet the Company's stock option grant needs under the 1994 Plan at least until the Company's Annual Meeting of Shareholders in 2000. As of March 15, 1999, 3,216,865 shares had been issued upon the exercise of options granted under the 1994 Plan, 8,870,363 shares were subject to outstanding options, and there were 1,912,772 shares (not including the 5,000,000-share increase subject to shareholder approval) remaining available for option grants under the 1994 Plan. AT THE ANNUAL MEETING, THE SHAREHOLDERS WILL BE REQUESTED TO CONSIDER AND APPROVE THE AMENDMENT TO THE 1994 PLAN INCREASING THE NUMBER OF SHARES AUTHORIZED FOR ISSUANCE THEREUNDER BY 5,000,000 SHARES. THE AFFIRMATIVE VOTE OF A MAJORITY OF THE SHARES OF THE COMPANY'S COMMON STOCK PRESENT OR REPRESENTED AND ENTITLED TO VOTE AT THE ANNUAL MEETING WILL BE REQUIRED TO APPROVE THE AMENDMENT TO THE 1994 PLAN. THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR APPROVAL OF THE AMENDMENT. NEW PLAN BENEFITS Grants under the 1994 Plan are made at the discretion of the Compensation Committee to whom the Board of Directors has delegated the administration of the 1994 Plan. Because future optionees, the number of shares subject to option grants and exercise prices have not yet been determined, future grants under the 1994 Plan are not yet determinable. SUMMARY OF 1994 PLAN A summary of the principal provisions of the 1994 Plan is set forth below and is qualified in its entirety by reference to the 1994 Plan. A copy of the 1994 Plan is available from the Company's Secretary upon request. PURPOSE The purposes of the 1994 Plan are to (i) attract and retain the services of selected key employees who the Company believes are in a position to make a material contribution to the successful operation of -16- 19 the Company's business; (ii) motivate such persons, by means of performance-related incentives, to achieve the Company's business goals; and (iii) enable such persons to participate in the long-term growth and financial success of the Company by providing them with an opportunity to purchase stock of the Company. ADMINISTRATION The 1994 Plan is required to be administered by a committee designated by the Board of Directors and comprised of not less than two disinterested non-employee Board members. The 1994 Plan is currently administered by the Compensation Committee of the Board, which is comprised of four disinterested non-employee directors. The interpretation and construction of any provision of the 1994 Plan is within the sole discretion of the members of the Compensation Committee, whose determination is final and binding. ELIGIBILITY The 1994 Plan provides that nonstatutory stock options and incentive stock options may be granted only to employees (including officers and directors who are also employees) of the Company. As administrator of the 1994 Plan, the Compensation Committee selects the optionees and determines the type of option (i.e., incentive or nonstatutory) and the number of shares to be subject to each option. In making such determination, there is taken into account a number of factors, including the employee's position and responsibilities, individual job performance, salary, previous stock option grants (if any), length of service to the Company, and other relevant factors. As of March 15, 1999, approximately 580 persons were eligible to receive options under the 1999 Plan, all of whom were holding options under such Plan. TERMS OF OPTIONS Options granted under the 1994 Plan may be either "incentive stock options" as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code), or nonstatutory stock options. Each option is evidenced by a written stock option agreement between the Company and the optionee and is subject to the following additional terms and conditions: (a) Number of Shares: The aggregate fair market value (determined as of the grant date) of the stock for which an employee may be granted incentive stock options that first become exercisable during any one calendar year under all the Company's plans may not exceed $100,000. In addition, the maximum number of shares which may be awarded as options under the 1994 Plan during any calendar year to any one optionee may not exceed 800,000 shares. (b) Exercise of the Option: The optionee must earn the right to exercise the option by continuing to work for the Company. Options granted under the 1994 Plan will become exercisable at such times and in such cumulative installments as the Compensation Committee determines subject to earlier termination of the option upon termination of the optionee's employment for any reason. Options are typically exercisable in cumulative installments (e.g., equal quarterly installments) over periods ranging up to five years. An option is exercised by giving to the Company written notice of exercise specifying the number of shares of Common Stock as to which the option is being exercised and by tendering payment to the Company of the purchase price. The form of payment for shares to be issued upon the exercise of an option is determined by the Compensation Committee and may consist of cash, check, previously owned shares of Common Stock, -17- 20 a combination thereof or such other consideration as is determined by the Compensation Committee. (c) Exercise Price: The exercise price per share for the shares to be issued pursuant to the exercise of an option is determined by the Committee and may not be less than 100% of the fair market value of the Common Stock on the grant date. The fair market value of the Common Stock on the date of an option grant will be equal to the closing sales price of the Common Stock on The Nasdaq Stock Market as reported in The Wall Street Journal on the date of the option grant. On March 15, 1999, the closing sales price of the Company's Common Stock on The Nasdaq Stock Market was $11.31 per share. (d) Termination of Employment: If an optionee's employment with the Company is terminated for any reason, other than death or total and permanent disability, the option may be exercised within three months after such termination as to all or part of the shares as to which the optionee was entitled to exercise the option at the time of termination. (e) Death or Disability: If an optionee should die or become permanently and totally disabled while employed by the Company, his or her options may be exercised at any time within six months after such death or disability, but only to the extent the optionee was entitled to exercise the options at the date of his or her termination of employment due to such death or disability. (f) Expiration of Options: Options may not have a term greater than ten years from the grant date. No option may be exercised after its expiration. (g) Nontransferability of Option: An option is nontransferable by the optionee, other than by will or the laws of descent and distribution or transfers between spouses incident to a divorce, and is exercisable only by the optionee during his or her lifetime or, in the event of the death of the optionee, by the estate of the optionee or by a person who acquires the right to exercise the option by bequest or inheritance. (h) Other Provisions: The option agreement may contain such other terms, provisions and conditions not inconsistent with the 1994 Plan as may be determined by the Compensation Committee. ADJUSTMENT UPON CHANGES IN CAPITALIZATION OR CONTROL In the event that a change, such as a stock split or stock dividend, is made in the Company's capitalization which affects the stock for which options are exercisable under the 1994 Plan, appropriate adjustment will be made in the exercise price of and the number of shares covered by outstanding options and in the number of shares available for issuance under the 1994 Plan. In general, unless the terms of an option expressly provide otherwise, in the event of a dissolution or liquidation of the Company, a sale of substantially all of the assets of the Company, or the merger, consolidation or reorganization of the Company with or into another corporation as a result of which the Company is not the surviving corporation, outstanding options will be assumed by the successor corporation or the Board of Directors will declare that any option will terminate as of a date fixed by the Board which is at least 30 days after notice thereof is given to optionees and permit each optionee to exercise all or a portion of the shares covered by such option, including shares as to which the option would not otherwise be exercisable. -18- 21 AMENDMENT AND TERMINATION The Compensation Committee may amend or terminate the 1994 Plan at any time or from time to time without the approval of the Company's shareholders; provided, however, that approval of the holders of voting shares represented and entitled to vote at a valid meeting of shareholders is required for any amendment to the 1994 Plan which would: (a) materially increase the number of shares which may be issued thereunder other than in connection with an adjustment upon changes in capitalization; (b) materially change the designation of the class of employees eligible to participate; (c) remove the administration of the 1994 Plan from the Board of Directors or its committee; (d) extend the term of the 1994 Plan beyond its initial ten-year term; (e) materially increase the benefits to participants under the 1994 Plan; or (f) materially modify the requirements as to eligibility for participation. In any event, the 1994 Plan will terminate on the tenth anniversary of its adoption by the Board of Directors (i.e., April 3, 2004), provided that any options then outstanding will remain outstanding until they expire by their terms. TAX INFORMATION The federal tax consequences of options are complex and subject to change. The following discussion is only a brief summary of the general federal income tax rules currently in effect which are applicable to stock options. A taxpayer's particular situation may be such that some variation of the general rules may apply. This summary does not cover the state, local or foreign tax consequences of the grant or exercise of options under the 1994 Plan or the disposition of shares acquired upon exercise of such options or federal estate tax or state estate, inheritance or death taxes. INCENTIVE STOCK OPTIONS If an option granted under the 1994 Plan is treated as an "incentive stock option" as defined in Section 422 of the Code, the optionee will not recognize any income for regular income tax purposes upon either the grant or the exercise of the option, and the Company will not be allowed a deduction for federal tax purposes. As discussed below, the tax treatment to the optionee and the Company upon an optionee's sale of the shares will depend primarily upon whether the optionee has met certain holding period requirements at the time of sale. In addition, the exercise of an incentive stock option may subject the optionee to alternative minimum tax liability in the year of exercise. If an optionee exercises an incentive stock option and does not dispose of the shares received within the period ending on the later of (i) two years from the date of the grant of such option or (ii) one year after the exercise of the option, any gain realized upon disposition of the shares will be characterized as long-term capital gain subject to a maximum federal income tax rate of 20%. The amount of gain realized on the disposition of the shares will be equal to the difference between the amount realized on the disposition and the optionee's tax basis in the shares. If the optionee does not dispose of the shares within the holding period specified above, the Company will not be entitled to a federal income tax deduction at any time. If the optionee disposes of the shares either within two years from the date the option is granted or within one year after the exercise of the option, such disposition will be treated as a "disqualifying disposition" for federal income tax purposes and an amount equal to the difference between (i) the lesser of the fair market value of the shares on the date of exercise and the amount realized on the disposition, and (ii) the exercise price will be taxed as ordinary income subject to a maximum marginal federal income tax rate of 39.6% in the taxable year in which the disposition occurs. The excess, if any, of the amount realized over the fair market value of the shares at the time of the exercise of the option will be treated as short-term or long-term capital gain, as the case may be. An optionee will be generally considered to have disposed of shares if he or she sells, exchanges, makes a gift of or transfers legal title to such shares (except by pledge, in certain non-taxable exchanges, in an -19- 22 insolvency proceeding, incident to a divorce, or upon death). The exercise of an incentive stock option may subject an optionee to alternative minimum tax liability in the year of exercise because the excess of the fair market value of the shares at the time an incentive stock option is exercised over the exercise price is an adjustment in determining an optionee's alternative minimum taxable income for such year. Consequently, an optionee may be obligated to pay alternative minimum tax in the year he or she exercises an incentive stock option. If a disqualifying disposition occurs in the same year as an option is exercised, the amount of ordinary income resulting from such disposition would generally offset any adjustment to alternative minimum taxable income for the year of exercise. In the case of a disqualifying disposition which occurs after the year of exercise, an individual would be required to recognize alternative minimum taxable income in the year of exercise and ordinary income in the year of such disqualifying disposition in an amount determined under the rules described above. Optionees are urged to consult their tax advisors concerning the applicability of the alternative minimum tax to their own circumstances. In general, there will be no federal income tax consequences to the Company upon the grant, exercise or termination of an incentive stock option. However, in the event an optionee sells or disposes of stock received upon the exercise of an incentive stock option prior to satisfying the two-year and one-year holding periods described above, the Company will be entitled to a deduction for federal income tax purposes in the year of such disposition in an amount equal to the ordinary income, if any, recognized by the optionee upon disposition of the shares, provided the Company has satisfied its reporting obligations under the Code. NONSTATUTORY STOCK OPTIONS Nonstatutory stock options granted under the 1994 Plan do not qualify as "incentive stock options" and, accordingly, do not qualify for any special tax benefits to the optionee. An optionee will not recognize any income at the time he or she is granted nonstatutory stock options because such options are not actively traded on an established market and will have no readily ascertainable fair market value at the time of grant. However, upon the exercise of a nonstatutory stock option, the optionee will generally recognize ordinary income for federal income tax purposes measured by the excess of the then fair market value of the shares over the exercise price. The income realized by the optionee will be treated as compensation income subject to income tax withholding by the Company out of the other compensation paid to the optionee. If such earnings are insufficient to pay the withholding tax, the optionee will be required to make a direct payment to the Company to cover the withholding tax liability. Upon a sale of any shares acquired pursuant to the exercise of a nonstatutory stock option, the difference between the sale price and the optionee's tax basis in the shares will be treated as a long-term or short-term capital gain or loss, as the case may be, depending on the optionee's holding period for the shares without "tacking on" any holding period for the option. The optionee's tax basis for determination of such gain or loss will ordinarily be the sum of (i) the amount paid for such shares (i.e., the exercise price), plus (ii) any ordinary income recognized as a result of the exercise of such option. If the optionee has held the shares for more than one year at the time of sale, the capital gain will be subject to a maximum federal income tax rate of 20%. If the holding period for the shares is shorter, the maximum marginal federal income tax rate will be 39.6%. In general, there will be no federal tax consequences to the Company upon the grant or termination of a nonstatutory stock option or the sale or disposition of the shares acquired upon exercise of a nonstatutory stock option. However, upon the exercise of a nonstatutory stock option, the Company will be entitled to a deduction to the extent and in the year that ordinary income from the exercise of the option is recognized by the optionee, provided the Company has satisfied its withholding and reporting obligations under the Code and Income Tax Regulations relating to the reporting of the transaction to the Internal Revenue Service and the optionee. -20- 23 PROPOSAL 3 - RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS The Board of Directors has appointed PricewaterhouseCoopers LLP, independent accountants, to audit the Company's consolidated financial statements for the year ending December 31, 1999, and recommends that shareholders vote for ratification of such appointment.

ELIGIBILITY. Options may be granted under the Plan only to Employees. An Employee who has been granted an Option may, if he or she is otherwise eligible, be granted additional Options. 6. TERMS AND CONDITIONS OF OPTIONS. Options granted pursuant to the Plan by the Committee shall be either Incentive Stock Options or Non-Statutory Stock Options and shall be evidenced by an Option Agreement providing, in addition to such other terms as the Committee may deem advisable, the following terms and conditions: a. Time of Granting Options. The date of grant of an Option shall for all purposes, be the date on which the Committee makes the determination granting such Option. Notice of the determination shall be given to each Optionee within a reasonable time after the date of such grant. b. Number of Shares. Each Option Agreement shall state the number of Shares to which it pertains and whether such Option is intended to constitute an Incentive Stock Option or a Non-Statutory Stock Option. The maximum number of Shares which may be awarded as Options under the Plan during any calendar year to any Optionee is Eight Hundred Thousand (800,000) Shares*. If an Option held by an Employee of the Company is canceled, the canceled Option shall continue to be counted against the maximum number of Shares for which Options may be granted to such Employee and any replacement Option granted to such Employee shall also count against such limit. - ------------------------ * Such number of shares has been adjusted to reflect the Company's two-for-one stock splits effective on each of March 17, 1995, August 8, 1997 and June 19, 1998. -4- 28 c. Exercise Price. The exercise price per Share for the Shares to be issued pursuant to the exercise of an Option, shall be such price as is determined by the Committee; provided, however, such price shall in no event be less than one-hundred percent (100%) with respect to Non-Statutory Stock Options, and one hundred percent (100%) with respect to Incentive Stock Options, of the Fair Market Value per Share on the date of grant. In the case of an Incentive Stock Option granted to an Employee who, at the time the Incentive Stock Option is granted, owns or is deemed to own (by reason of the attribution rules applicable under Section 424(d) of the Code) stock possessing more than ten percent (10%) of the combined voting power of all classes of stock of the Company, the exercise price per Share shall be no less than one-hundred-ten percent (110%) of the Fair Market Value per Share on the date of grant. d. Medium and Time of Payment. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Committee and may consist entirely of cash, check or Shares having a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment, or such other consideration and method of payment permitted under any laws to which the Company is subject which is approved by the Committee; provided, however, that the Optionee shall be required to pay in cash an amount necessary to satisfy the Company's withholding obligations. In the case of an Incentive Stock Option, such provision shall be determined on the date of the grant. If the consideration for the exercise of an Option is the surrender of previously acquired and owned Shares, the Optionee will be required to make representations and warranties satisfactory to the Company regarding his or her title to the Shares used to effect the purchase, including without limitation representations and warranties that the Optionee has good and marketable title to such Shares free and clear of any and all liens, encumbrances, charges, equities, claims, security interests, options or restrictions, and has full power to deliver such Shares without obtaining the consent or approval of any person or governmental authority other than those which have already given consent or approval in a manner satisfactory to the Company. The value of the Shares used to effect the purchase shall be the Fair Market Value of such Shares on the date of exercise as determined by the Committee in its sole discretion, exercised in good faith. e. Term of Options. The term of an Incentive Stock Option may be up to ten (10) years from the date of grant thereof; provided, however, that the term of an Incentive Stock Option granted to an Employee who, at the time the Incentive Stock Option is granted, owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company, shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Option. The term of a Non-Statutory Stock Option may be up to ten (10) years from the date such Employee first becomes vested in any portion of an Option award. -5- 29 The term of any Option may be less than the maximum term provided for herein as specified by the Committee upon grant of the Option and as set forth therein. f. Maximum Amount of Incentive Stock Options. To the extent that the aggregate Fair Market Value (determined at the time an Incentive Stock Option is granted) of the Shares with respect to which Incentive Stock Options are exercisable for the first time by an Optionee during any calendar year under all incentive stock option plans of the Company exceeds One Hundred Thousand Dollars ($100,000), the Options in excess of such limit shall be treated as Non-Statutory Stock Options. 7. EXERCISE OF OPTION. a. In General. Any Option granted hereunder to an Employee shall be exercisable at such times and under such conditions as may be determined by the Committee and as shall be permissible under the terms of the Plan, including any performance criteria with respect to the Company and/or the Optionee as may be determined by the Committee. An Option may be exercised in accordance with the provisions of the Plan as to all or any portion of the Shares then exercisable under an Option from time to time during the term of the Option. However, an Option may not be exercised for a fraction of a Share. b. Procedure. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company at its principal business office in accordance with the terms of the Option Agreement by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company, accompanied by any other agreements required by the terms of the Plan and/or Option Agreement or as required by the Committee and payment by the Optionee of all payroll, withholding or income taxes incurred in connection with such Option exercise (or arrangements for the collection or payment of such tax satisfactory to the Committee are made). Full payment may consist of such consideration and method of payment allowable under Section 6(d) of the Plan. c. Decrease in Available Shares. Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. d. Exercise of Stockholder Rights. Until the Option is properly exercised in accordance with the terms of this section, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Option is exercised, except as provided in Section 10 of the Plan. e. Termination of Eligibility. If an Optionee ceases to serve as an Employee for any reason other than death or permanent and total disability (within the meaning of Section 22(e)(3) of the Code) and thereby terminates his or her Continuous Status as an Employee he or she may, but only within three (3) months following the date he or she ceases his or her Continuous Status -6- 30 as an Employee (subject to any earlier termination of the Option as provided by its terms), exercise his or her Option to the extent that he or she was entitled to exercise it at the date of such termination. To the extent that he or she was not entitled to exercise the Option at the date of such termination, or if he or she does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. Notwithstanding anything to the contrary herein, the Committee may at any time and from time to time prior to the termination of a Non-Statutory Stock Option, with the consent of the Optionee, extend the period of time during which the Optionee may exercise his or her Non-Statutory Stock Option following the date he or she ceases his or her Continuous Status as an Employee; provided, however, that the maximum period of time during which a Non-Statutory Stock Option shall be exercisable following the date on which an Optionee terminates his or her Continuous Status as an Employee shall not exceed an aggregate of six (6) months, that the Non-Statutory Stock Option shall not be, or as a result of such extension become, exercisable after the expiration of the term of such Option as set forth in the Option Agreement and, notwithstanding any extension of time during which the Non-Statutory Stock Option may be exercised, that such Option, unless otherwise amended by the Committee, shall only be exercisable to the extent the Optionee was entitled to exercise it on the date he or she ceased his or her Continuous Status as an Employee. f. Death or Disability Of Optionee. If an Optionee's Continuous Status as an Employee ceases due to death or permanent and total disability (within the meaning of Section 22(e)(3) of the Code) of the Optionee, the Option may be exercised within six (6) months (or such other period of time not exceeding one (1) year as is determined by the Committee at the time of granting the Option) following the date of death or termination of employment due to permanent or total disability (subject to any earlier termination of the Option as provided by its terms), by the Optionee in the case of permanent or total disability, or in the case of death by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but in any case (unless otherwise determined by the Committee at the time of granting the Option) only to the extent the Optionee was entitled to exercise the Option at the date of his or her termination of employment by death or permanent and total disability. To the extent that he or she was not entitled to exercise such Option at the date of his or her termination of employment by death or permanent and total disability, or if he or she does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. g. Expiration of Option. Notwithstanding any provision in the Plan, including but not limited to the provisions set forth in Sections 7(e) and 7(f), an Option may not be exercised, under any circumstances, after the expiration of its term. h. Conditions on Exercise and Issuance. As soon as practicable after any proper exercise of an Option in accordance with the provisions of the Plan, the Company shall deliver to the Optionee at the principal executive office of the Company or such other place as shall be mutually agreed upon between the Company and the Optionee, a certificate or certificates representing the Shares for which the Option shall have been exercised. The time of issuance and delivery of the certificate or certificates representing the Shares for which the Option shall have been exercised may be postponed by the Company for such period as may be required by -7- 31 the Company, with reasonable diligence, to comply with any law or regulation applicable to the issuance or delivery of such Shares. Options granted under the Plan are conditioned upon the Company obtaining any required permit or order from appropriate governmental agencies, authorizing the Company to issue such Options and Shares issuable upon exercise thereof. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, applicable state law, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and may be further subject to the approval of counsel for the Company with respect to such compliance. i. Withholding or Deduction for Taxes. The grant of Options hereunder and the issuance of Shares pursuant to the exercise thereof is conditioned upon the Company's reservation of the right to withhold, in accordance with any applicable law, from any compensation or other amounts payable to the Optionee any taxes required to be withheld under Federal, state or local law as a result of the grant or exercise of such Option or the sale of the Shares issued upon exercise thereof. To the extent that compensation and other amounts, if any, payable to the Optionee are insufficient to pay any taxes required to be so withheld, the Company may, in its sole discretion, require the Optionee, as a condition of the exercise of an Option, to pay in cash to the Company an amount sufficient to cover such tax liability or otherwise to make adequate provision for the delivery to the Company of cash necessary to satisfy the Company's withholding obligations under Federal and state law. 8. NONTRANSFERABILITY OF OPTIONS. Options granted under the Plan may not be sold, pledged, assigned, hypothecated, gifted, transferred or disposed of in any manner, either voluntarily or involuntarily by operation of law, other than by will or by the laws of descent or distribution or transfers between spouses incident to a divorce. 9. HOLDING PERIOD. In the case of officers and directors of the Company, at least six (6) months must elapse from the date of grant of the Option to the date of disposition of the underlying Shares. 10. ADJUSTMENT UPON CHANGE IN CORPORATE STRUCTURE. a. Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Option, and the number of Shares which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the exercise or purchase price per Share covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split or combination or the payment of a stock dividend (but only on the Common -8- 32 Stock) or any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company (other than stock awards to Employees); provided, however, that the conversion of any convertible securities of the Company shall not be deemed to have been effected without the receipt of consideration. Such adjustment shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive.
