                                 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 Wednesday, May 21, 1997, at 9:30
a.m., Eastern Daylight-Saving 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 5151 McCrimmon Parkway, Suite 216, Morrisville, North
Carolina 27560.

     These proxy solicitation materials were first mailed on or about April 10,
1997 to all shareholders entitled to vote at the Annual Meeting.

     Only shareholders of record at the close of business on April 1, 1997 (the
"Record Date") are entitled to notice of, and to vote at, the Annual Meeting. At
the Record Date, 12,390,027 shares of 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 candidates receiving the highest number of votes up to the number of
directors to be elected 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." Broker non-votes are counted as shares that are
present and entitled to vote for purposes of determining a quorum. If a broker
indicates on the proxy that it does not have discretionary authority to vote on
a particular matter as to certain shares, those shares will be counted for
purposes of determining the presence of a quorum but will not be treated as
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-
<PAGE>

     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 1998 must be received by the Company no later than December 11, 1997 in order
that they may be included in the proxy statement and form of proxy relating to
that annual meeting. 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 21, 1997.


                       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 shall be 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 the earlier of his resignation,
removal or death.

     The names of the nominees, and certain information about them, are set
forth below:

INFORMATION REGARDING THE BOARD OF DIRECTORS AND ITS COMMITTEES

     The Board of Directors held a total of 14 meetings during 1996 and acted
six times by unanimous written consent. During 1996, each director of the
Company (other than Mr. Adams) attended at least 75% of the aggregate of the

which he was a director and the total number of meetings held by the committees
of the Board on which he served.

     The Audit Committee, which is presently comprised of Messrs. Adams,
Brenner, Oringer and Rager, met four times during 1996. The Audit Committee
recommends the engagement of independent auditors, reviews accounting policies,
internal accounting controls and results of audit engagements and

                                       -3-
<PAGE>

generally performs functions related to the financial condition and policies of
the Company. The Compensation Committee, which is presently comprised of Messrs.
Adams, Brenner, Oringer and Rager, met 12 times during 1996 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 and for assisting the Board of Directors
in matters involving executive compensation. 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 fee of
$3,000 (except the Chairman of the Board who is paid $4,000), plus $1,250 for
attending a Board of Directors' meeting in person or telephonically and
reimbursement for reasonable expenses for attending a Board of Directors'
meeting. In addition, each member of the Compensation Committee receives $500
per quarter (except the Chairman of the Compensation Committee who is paid $750)
and $1,250 for attending a Compensation Committee meeting in person or
telephonically. The Chairman of the Audit Committee receives $750 per quarter
and each member of the Audit Committee receives $750 for attending a committee
meeting in person or telephonically. Committee members also receive
reimbursement for reasonable expenses for attending a committee meeting.

     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 as of July 24, 1993 and each
non-employee director elected at the Company's annual shareholder meeting in
1996 automatically received and, subject to the availability of shares under the
Director Plan, each non-employee director elected at the Company's annual
shareholder meeting in 1999 will automatically be granted, a nonstatutory stock
option to purchase 30,000 shares of the Company's Common Stock (the dates of
such grants are hereinafter referred to as "Regular Grant Dates"). A
non-employee director elected or appointed to the Board other than on a Regular
Grant Date automatically receives a nonstatutory stock option covering a pro
rata number of shares. All options granted under the Director Plan have an
exercise price equal to the fair market value of the Common Stock on the date of
grant and a term of seven years and terminate seven months after a director
ceases to serve as a non-employee director of the Company. Options granted on a
Regular Grant Date vest in 12 equal quarterly installments as long as the holder
remains a non-employee director of the Company; options granted on dates other
than Regular Grant Dates vest in the same number of quarterly installments as
would be remaining with respect to the unvested portion of the options granted
under the Director Plan on the last Regular Grant Date.

     In August 1996, the Company entered into a Consulting Agreement with Mr.
Oringer pursuant to which Mr. Oringer performed consulting services for the
Company through December 1996 in consideration for $30,000 and the issuance to
him of five-year warrants to purchase 30,000 shares of the Company's Common
Stock at an exercise price of $9.50 per share (i.e., the closing sales price of
the Company's Common Stock on The Nasdaq Stock Market on the date of grant). The
warrants vested in installments of 1,250 shares each, with one installment
vesting for each day of services performed by Mr. Oringer under the Consulting
Agreement, and are fully vested as to all 30,000 shares.

     the shares in the Company for investment only. Mr. Asscher has from time to

(1)  Such options were granted under the Company's 1994 Stock Option Plan (the
     "1994 Plan"), vest and become exercisable in 20 equal quarterly
     installments over five years and were granted for terms of ten years
     subject to earlier termination under certain circumstances relating to
     termination of employment.

(2)  In 1996, the Company granted options to employees under the 1994 Plan to
     purchase an aggregate of 1,145,250 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
     will be forfeited prior to exercise. Black-Scholes Model input assumptions
     included: (a) an expected time to exercise of five years; (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 Tekelec Common Stock,
     calculated using daily closing sales prices for the period from January
     1992 to December 1996; 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 1992-1996 (18.46%) compounded over the expected years to
     exercise of five years. 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.

EMPLOYMENT AGREEMENTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

     In May 1993, the Company implemented an officer severance plan (the
"Severance Plan") pursuant to which 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.

     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. Toomer, Suzuki, Godin and Gardner if their employment were
terminated as of April 1, 1997 and they were eligible for severance benefits
under the Severance Plan would be $316,250, $321,780, $294,000 and $92,250,
respectively. 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. Mr. Alford, William Minchin, the
Company's former Vice President, Operations, and William Shaw, the Company's
former Senior Vice President and General Manager, Network Diagnostic Division,
whose employment relationships with the Company were terminated during 1996,
have received or will receive severance compensation under the Severance Plan
totalling $457,500, $164,656 and $179,016, respectively. In addition, upon the
termination of Messrs. Alford's and Minchin's employment relationships with the
Company, the vesting of options to purchase 20,000 and 11,700 shares,
respectively, was accelerated and such options became vested and

                                       -9-
<PAGE>

exercisable in full as of their respective dates of termination. In the case of
Mr. Alford, such options were accelerated pursuant to the terms of his original
option agreement with the Company. In connection with the termination of Mr.
Alford's employment with the Company, the Company also agreed to pay up to
$25,000 directly to an outplacement services agency for outplacement services to
be rendered to Mr. Alford.

     In February 1994, the Company agreed that in the event Mr. Godin's
employment with the Company is terminated under circumstances entitling him to
severance benefits under the Severance Plan, then the unvested installments of
an option to purchase 50,000 shares of the Company's Common Stock granted to him
in February 1994 will vest and become exercisable in full upon such termination.
As of March 1, 1997, such option was unvested as to 20,000 shares.

     In March 1997, Mr. Toomer entered into an agreement with the Company
pursuant to which the Company agreed to pay to Mr. Toomer, in lieu of any
benefits which might otherwise be payable to him under the Severance Plan, a
lump sum payment in the amount of $400,000 upon the termination of his
employment with the Company after June 30, 1997 for any reason or upon his death
or disability at any time. The agreement also provides that (i) if Mr. Toomer
remains an officer of the Company through December 31, 1997, all installments of
stock options granted to him under the Company's 1994 Stock Option Plan that are
scheduled to vest after December 31, 1997 will vest in full and become
immediately exercisable on December 31, 1997, and (ii) if Mr. Toomer's
employment is terminated prior to December 31, 1997 for any reason other than
his voluntary termination without "good reason" or by the Company "for cause"
(as such terms are defined in the Officer Severance Plan), then the warrants to
purchase 40,300 shares of the Company's Common Stock granted to Mr. Toomer in
January 1997 will vest in full and become immediately exercisable. See "Certain
Relationships and Related Transactions" below.

TEKELEC, LTD. RETIREMENT PLAN

     In January 1990, Tekelec, Ltd., the Company's wholly owned Japanese
subsidiary, 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
other than at retirement age with at least three years of eligible service is
entitled to receive one lump sum payment 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 or other relative.

     Mr. Suzuki is one of two current participants in the Plan. As of April 1,
1997, Mr. Suzuki was credited with 11 years of eligible service and would be
entitled to receive approximately $281,000 as a lump sum payment under the Plan
if his employment were terminated by Tekelec, Ltd.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 1996, the Compensation Committee consisted of Messrs. Adams,
Brenner, Oringer and Rager until July 1996, of Messrs. Adams, Rager and Brenner
from July 1996 until November 1996, and of Messrs. Adams, Brenner, Oringer and
Rager thereafter. 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. With respect to calendar year 1996 compensation of the Company's
executive officers, the Board of Directors was responsible for determining the
annual base salaries of such officers and approving the terms of the officer
bonus plan and the award of discretionary bonuses. The Board has delegated to
the Compensation Committee the responsibility of administering the Company's
stock option plans pursuant to which stock options are granted as an additional
incentive to key employees.

     The reports on executive compensation by the Board of Directors and the
Compensation Committee and the Performance Graph on page 14 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 compensation
program consists of three basic components -- annual base salaries, cash bonuses
and stock options.

     The Board of Directors reviews 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 1996, principally in recognition of the Company's improved financial
results and achievement of certain corporate objectives in 1995, the Board
increased the annual base salaries of the Company's executive officers named in
the Summary Compensation Table by 4.4% to 11.1% over 1995 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 Officer Bonus Plan for 1996, 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 both the revenue goal and the
operating income goal set forth in the Company's business plan.

                                      -11-

     Under the terms of the Officer Bonus Plan, no bonuses were earned by the
Company's executive officers because the Company did not meet the Plan's
financial performance goals. In recognition, however, of the achievement in 1996
of individual goals by certain of the Company's executive officers, the Board
awarded discretionary cash bonuses to Messrs. Toomer, Godin, Suzuki and Gardner
in amounts ranging from $5,000 to $25,000 and from 4.5% to 10.9% as a percentage
of an officer's annual base salary.

     The Board was also responsible for determining the annual base salary of
Philip Alford, the Company's President from January 1994 until November 1996 and
Chief Executive Officer from July 1995 until December 1996. In determining Mr.
Alford's annual base salary for 1996, the Board took into consideration the same
factors that were considered in setting the annual base salaries of the
Company's other executive officers. Although Mr. Alford was a member of the
Board of Directors, he did not participate in any discussions or decisions of
the Board or the Compensation Committee regarding his salary. For services
rendered in 1996, Mr. Alford's cash compensation consisted of base salary in the
amount of $250,000 (an 11.1% increase over his 1995 salary).

     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
1997 would exceed the $1 million limitation per officer.

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.

                                      -12-
<PAGE>

     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 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 in the employ of the Company. In 1996, options to purchase an
aggregate of 67,600 shares of Common Stock were granted to all executive
officers as a group (including options to purchase 18,500 shares granted to Mr.
Alford) and represented 5.9% of all options granted in 1996. Information
concerning options granted during 1996 to the executive officers named in the
Summary Compensation Table is provided in the table entitled "Executive
Compensation and Other Information Option Grants in 1996."

                 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, 1996:

     The Company sells products to Tekelec-Airtronic and its wholly owned
subsidiaries which serve as distributors of the Company's products in Europe.
During 1996, the aggregate sales of the Company's products to Tekelec-Airtronic
and its subsidiaries were approximately $4,130,000. As of December 31, 1996,
Tekelec-Airtronic and its subsidiaries owed the Company approximately $2,381,000
for purchases of the Company's products, of which approximately $1,922,000 was
owed as of March 1, 1997.

     The Company also purchases certain telecommunications test equipment and
components from Tekelec-Airtronic and certain of its subsidiaries. During 1996,
the Company purchased such equipment and components from Tekelec-Airtronic and
its subsidiaries at an aggregate cost of approximately $125,000. As of December
31, 1996, the Company owed approximately $145,000 for purchases of such
equipment and components, of which approximately $140,000 was owed as of March
1, 1997. The Company anticipates that during 1997 it will continue to purchase
telecommunications test equipment and components from Tekelec-Airtronic and its
subsidiaries, and expects that the aggregate amount of such purchases will not
be significantly greater than the aggregate amount of such purchases during
1996.

     In January 1997, the Company issued to Mr. Toomer warrants to purchase
40,300 shares of the Company's Common Stock at an exercise price of $18.625 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 three equal
installments on June 30, 1997, September 30, 1997 and December 31, 1997 as long
as Mr. Toomer remains an employee of the Company. The warrants may vest earlier
under certain circumstances upon the termination of Mr. Toomer's employment with
the Company. See "Executive Compensation and Other Information - Employment
Agreements and Termination of Employment and Change-in-Control Arrangements"
above.

          PROPOSAL 2 - APPROVAL OF AMENDMENTS TO 1994 STOCK OPTION PLAN

     In 1994, the Board of Directors of the Company adopted and the shareholders
of the Company approved the 1994 Stock Option Plan (the "1994 Plan") under which
800,000 shares of Common Stock were initially authorized for issuance pursuant
to the exercise of stock options granted thereunder. The 1994 Plan was amended
in 1995 and 1996 to increase the number of shares authorized for issuance
thereunder by an aggregate of 1,200,000 shares.

     In February and March 1997, the Board of Directors further amended the 1994
Plan, subject to shareholder approval, to increase the number of shares
authorized for issuance thereunder by 100,000 and 900,000 shares, respectively.
If such increase is approved, a total of 3,000,000 shares will have been
authorized for issuance under the 1994 Plan. To the extent options are granted
to purchase any of such additional 1,000,000 shares prior to obtaining
shareholder approval of the amendments to the 1994 Plan, such options will be
expressly conditioned upon obtaining such approval.

     As of March 24, 1997, under the 1994 Plan, a total of 148,326 shares had
been issued upon the exercise of options granted, a total of 1,841,816 shares
was subject to outstanding options, and there were 9,858 shares (not including
the 1,000,000-share increase subject to shareholder approval) remaining
available for option grants.

NEW PLAN BENEFITS

     Grants under the 1994 Plan to purchase any of the additional 1,000,000
shares subject to shareholder approval will be made at the discretion of the
Compensation Committee to whom the Board of Directors has delegated the
administration of the 1994 Plan. As of April 10, 1997, no such grants had been
made. Future benefits under the 1994 Plan are therefore not yet determinable
because future optionees, the number of shares subject to option grants and
exercise prices have not yet been determined.

     AT THE ANNUAL MEETING, THE SHAREHOLDERS WILL BE REQUESTED TO CONSIDER AND
APPROVE THE AMENDMENTS TO THE 1994 PLAN INCREASING THE NUMBER OF SHARES
AUTHORIZED FOR ISSUANCE THEREUNDER BY AN AGGREGATE OF 1,000,000 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 AMENDMENTS TO THE 1994 PLAN. THE BOARD OF DIRECTORS
RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR APPROVAL OF THE AMENDMENTS.

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 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

                                      -15-
<PAGE>

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 non-employee Board
members. The 1994 Plan is currently administered by the Compensation Committee
of the Board, which is comprised of four 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 1, 1997, approximately 371
persons were eligible to receive options and 366 optionees were holding options
under the 1994 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 200,000 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., 20 equal quarterly installments) over
         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 at the time of grant and may consist of cash, check,
         previously owned shares of Common Stock, a combination thereof or such
         other consideration as is determined by the Compensation Committee.

                                      -16-
<PAGE>

     (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 April 1, 1997,
         the closing sales price of the Company's Common Stock on The Nasdaq
         Stock Market was $21.00 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 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.

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

                                      -17-
<PAGE>

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, then 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. Upon a sale of the shares, the tax treatment to the
optionee and the Company will depend primarily upon whether the optionee has met
certain holding period requirements at the time of sale. In addition, as
discussed below, 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 two years of the date of the grant of such option and
within one year after the exercise of the option, whichever ends later, any gain
realized upon disposition will be characterized as long-term capital gain, and
any loss will be long-term capital loss. In either such case, the Company will
not be entitled to a federal income tax deduction.

     If the optionee disposes of the shares either within two years after 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 and an amount
equal to the lesser of (1) the fair market value of the shares on the date of
exercise less the purchase price or (2) the amount realized on the disposition
less the purchase price will be taxed as ordinary income in the taxable year in
which the disposition occurs. Any such ordinary income will increase the
optionee's tax basis for purposes of determining gain or loss on the sale or
exchange of such shares. 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, and any
loss realized upon the disposition will be treated as a capital loss. 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, a transfer in insolvency
proceedings, incident to a divorce, or upon death). If the amount realized is
less than the purchase price, generally the optionee will not recognize income.

                                      -18-
<PAGE>

     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 option 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
disqualifying disposition is included in 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 an
adjustment to alternative minimum taxable income in the year of exercise and
ordinary income resulting from such disqualifying disposition in the year of
such disposition. An optionee's regular tax liability is affected by the
availability of a credit for prior year alternative minimum tax, a basis
adjustment for alternative minimum tax and other complex rules. 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 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 an amount equal to the ordinary income, if any,
recognized by the optionee upon disposition of the shares.

     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 a nonstatutory option. However, upon its exercise, the
optionee will generally recognize ordinary income for regular income tax
purposes measured by the excess of the then fair market value of the shares over
the option price. The income realized by the optionee will be subject to income
tax withholding by the Company out of the 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 basis in the shares will be treated as a long-term or short-term
capital gain or loss, as the case may be. The optionee's basis for determination
of gain or loss upon any subsequent disposition of shares acquired upon the
exercise of a nonstatutory stock option will ordinarily be the sum of the amount
paid for such shares plus any ordinary income recognized as a result of the
exercise of such option.

     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 obligations under the Code.

Directors to administer the Plan and comprised of not less than two directors,
each of whom is a Disinterested Person. In addition, each director designated by
the Board of Directors to administer the Plan shall be an "outside director" as

Agreement; (vii) to accelerate the exercise date of any Option; (viii) to

the Optionee, to amend any such agreement; (ix) to interpret the Plan or any
agreement entered into

<PAGE>

with respect to the grant or exercise of Options, to determine the eligibility
of an Employee for benefits hereunder and the amount thereof; (x) to authorize
any person to execute on behalf of the Company any instrument required to
effectuate the grant of an Option previously granted or to take such other
actions as may be necessary or appropriate with respect to the Company's rights
pursuant to Options or agreements relating to the grant or exercise thereof; and
(xi) to make such other determinations and establish such other procedures as it
deems necessary or advisable for the administration of the Plan.

     c. All decisions, determinations and interpretations of the Committee shall
be final and binding on all Optionees and any other holders of any Options
granted under the Plan.

     d. The Committee shall keep minutes of its meetings and of the actions
taken by it without a meeting. A majority of the Committee shall constitute a
quorum, and the actions of a majority at a meeting, including a telephone
meeting, at which a quorum is present, or acts approved in writing by a majority
of the members of the Committee without a meeting, shall constitute acts of the
Committee.

     e. The Company shall pay all original issue and transfer taxes with respect
to the grant of Options and/or the issue and transfer of Shares pursuant to the
exercise thereof, and all other fees and expenses necessarily incurred by the
Company in connection therewith; provided, however, that the person exercising
an Option shall be responsible for all payroll, withholding, income and other
taxes incurred by such person on the date of exercise of an Option or transfer
of Shares.

5. 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 Two Hundred Thousand

                                       -4-
<PAGE>

(200,000) 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.

     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.

*  Such number of shares has been adjusted to reflect the Company's two-for-one
   stock split effective March 17, 1995.

                                       -5-
<PAGE>

     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.

     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

                                       -6-
<PAGE>

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 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

                                       -7-
<PAGE>

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 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.

                                       -8-
<PAGE>

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 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. Except as expressly provided herein, no issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of Shares subject to the Plan or an Option.

     b. In the event of the proposed dissolution or liquidation of the Company,
or in the event of a proposed sale of all or substantially all of the assets of
the Company (other than in the ordinary course of business), or the merger or
consolidation of the Company with or into another corporation, as a result of
which the Company is not the surviving and controlling corporation, the Board of
Directors shall (i) make provision for the assumption of all outstanding options
by the successor corporation or (ii) declare that any Option shall terminate as
of a date fixed by the Board of Directors which is at least thirty (30) days
after the notice thereof to the Optionee and shall give each Optionee the right
to exercise his or her Option as to all or any part of the Optioned Stock,
including Shares as to which the Option would not otherwise be exercisable
provided such exercise does not violate Section 7(e) of the Plan.

     c. No fractional shares of Common Stock shall be issuable on account of any
action aforesaid, and the aggregate number of shares into which Shares then
covered by the Option, when changed as the result of such action, shall be
reduced to the largest number of whole shares resulting from such action, unless
the Board of Directors, in its sole discretion, shall determine to issue scrip
certificates in respect to any fractional shares, which scrip certificates, in
such event shall be in a form and have such terms and conditions as the Board of
Directors in its discretion shall prescribe.

                                       -9-
<PAGE>

11. STOCKHOLDER APPROVAL.

     Effectiveness of the Plan shall be subject to approval by the stockholders
of the Company within twelve (12) months before or after the date the Plan is
adopted; provided, however, that Options may be granted pursuant to the Plan
subject to subsequent approval of the Plan by such stockholders. Stockholder
approval shall be obtained by the affirmative votes of the holders of a majority
of voting Shares present or represented and entitled to vote at a meeting of
stockholders duly held in accordance with the laws of the state of California.

12. AMENDMENT AND TERMINATION OF THE PLAN.

     a. Amendment and Termination. The Committee may amend or terminate the Plan
from time to time in such respects as the Committee may deem advisable and shall
make any amendments which may be required so that Options intended to be
Incentive Stock Options shall at all times continue to be Incentive Stock
Options for the purpose of Section 422 of the Code; provided, however, that
without approval of the holders of a majority of the voting Shares represented
or present and entitled to vote at a valid meeting of stockholders, no such
revision or amendment shall (i) materially increase the benefits accruing to
participants under the Plan; (ii) materially increase the number of Shares which
may be issued under the Plan, other than in connection with an adjustment under
Section 10 of the Plan; (iii) materially modify the requirements as to
eligibility for participation in the Plan; (iv) materially change the
designation of the class of Employees eligible to be granted Options; (v) remove
the administration of the Plan from the Board of Directors or its Committee; or
(vi) extend the term of the Plan beyond the maximum term set forth in Section 15
hereunder.

     b. Effect of Amendment or Termination. Except as otherwise provided in
Section 10 of the Plan, any amendment or termination of the Plan shall not
affect Options already granted and such Options shall remain in full force and
effect as if the Plan had not been amended or terminated, unless mutually agreed
otherwise between the Optionee and the Company, which agreement must be in
writing and signed by the Optionee and the Company. Notwithstanding anything to
the contrary herein, this 1994 Stock Option Plan shall not adversely affect,
unless mutually agreed in writing by the Company and an Optionee, the terms and
provisions of any Option granted prior to the date the Plan was approved by
stockholders as provided in Section 11 of the Plan.

13. INDEMNIFICATION.

     No member of the Committee or of the Board of Directors shall be liable for
any act or action taken, whether of commission or omission, except in
circumstances involving willful misconduct, or for any act or action taken,
whether of commission or omission, by any other member or by any officer, agent,
or Employee. In addition to such other rights of indemnification they may have

14. GENERAL PROVISIONS.

     a. Other Plans. Nothing contained in the Plan shall prohibit the Company
from establishing additional incentive compensation arrangements.

     b. No Enlargement of Rights. Neither the Plan, nor the granting of Shares,
nor any other action taken pursuant to the Plan shall constitute or be evidence
of any agreement or understanding, express or implied, that the Company will
retain an Employee for any period of time, or at any particular rate of
compensation. Nothing in the Plan shall be deemed to limit or affect the right
of the Company or any such corporations to discharge any Employee thereof at any
time for any reason or no reason.

     No Employee shall have any right to or interest in Options authorized
hereunder prior to the grant thereof to such eligible person, and upon such

provided herein and in the related Option Agreement, subject, however, to all
applicable provisions of the Company's Certificate of Incorporation, as the same
may be amended from time to time.

     c. Notice. Any notice to be given to the Company pursuant to the provisions
of the Plan shall be addressed to the Company in care of its Secretary (or such

hereunder shall be delivered personally or addressed to him or her at the

     Tekelec, a California corporation (the "Company"), hereby enters into this

     2. EXERCISE PRICE. The exercise price is $ __________ per Share, which
price is not less than one hundred percent (100%) of the Fair Market Value
thereof on the date of the grant.

     3. METHOD OF PAYMENT. The consideration to be paid for the Shares to be
issued upon the exercise of this Option may consist entirely of cash, check,
Shares already owned by the Optionee which have a Fair Market Value on the date
of surrender equal to the aggregate exercise price of the Shares as to which
this Option is exercised, or any combination of such methods of payment, subject
to the provisions of Section 6(d) of the Plan; provided, however, that the
Optionee shall be required to pay in cash an amount necessary to satisfy the
Company's withholding obligations.

     4. EXERCISE OF OPTION. This Option shall be exercisable during its term
only in accordance with the terms and provisions of the Plan and this Option as
follows:

          (a) This Option shall vest and be exercisable cumulatively in
____________________ ( ) equal quarterly installments commencing [e.g., with the
first installment vesting on ________________ and one additional installment
vesting on the last day of each calendar quarter thereafter, as long as the
Optionee continues to serve as an Employee]. An Optionee who has been in
continuous employment with the Company since the grant of this Option may
exercise the exercisable portion of his or her Option in whole or in part at any
time during his or her employment. However, an Option may not be exercised for a
fraction of a Share. In the event of the Optionee's termination of employment
with the Company or disability or death, the provisions of Sections 6 or 7 below
shall apply to the right of the Optionee to exercise the Option.
<PAGE>

          (b) This Option shall be exercisable by written notice which shall
state the election to exercise this Option, the number of Shares with respect to
which this Option is being exercised and such other representations and
agreements as may be required by the Company hereunder or pursuant to the
provisions of the Plan. Such written notice shall be signed by the Optionee and
shall be delivered in person or by certified mail to the Secretary of the
Company or such other person as may be designated by the Company. The written
notice shall be accompanied by payment of the purchase price and an executed
Notice of Exercise of Stock Option in the form attached hereto. The certificate
or certificates for the Shares as to which this Option is exercised shall be
registered in the name of the Optionee.

          (c) No rights of a stockholder shall exist with respect to the Shares
under this Option as a result of the mere grant of this Option or the exercise
of this Option. Such rights shall exist only after issuance of a stock
certificate in accordance with Section 7(h) of the Plan.

     5. RESTRICTIONS ON EXERCISE. This Option may not be exercised until such
time as the Plan has been approved by the stockholders of the Company as set
forth in Section 11 of the Plan, or if the issuance of Shares upon Optionee's
exercise or the method of payment of consideration for such Shares would
constitute a violation of any applicable Federal or state securities law or
other applicable law or regulation. As a condition to the exercise of the
Option, the Company may take such steps as in its judgment are reasonably

this Option is not exercised within the time specified herein, this Option shall
terminate. Notwithstanding the foregoing, this Option shall not be exercisable
after the expiration of the term set forth in Section 8 hereof.

right to exercise this Option by bequest or inheritance, or, in the case of
disability, by the Optionee, but in any case only to the extent the Optionee was
entitled to exercise this Option at the date of such termination. To the extent
that the Optionee was not entitled to exercise this Option at the date of
termination, or to the extent this Option is not exercised within the time
specified herein, this Option shall terminate. Notwithstanding the foregoing,
this Option shall not be exercisable after the expiration of the terms set forth
in Section 8 hereof.

Optionee at any time, with or without cause and with or without notice.
