                         ANNUAL MEETING OF STOCKHOLDERS
 
                                JANUARY 8, 1998
 
                            ------------------------
 
                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
    The enclosed proxy is solicited on behalf of Cyberonics, Inc. (the
"Company") for the Annual Meeting of Stockholders to be held on Thursday,
January 8, 1998, at 9:00 a.m., local time, at the South Shore Harbor Resort &
Conference Center, 2500 South Shore Boulevard, League City, Texas or any
adjournment or adjournments thereof, for the purposes set forth herein and in
the accompanying Notice of Annual Meeting.
 
    These Proxy solicitation materials were mailed on or about November 28, 1997
to all stockholders entitled to vote at the meeting.
 
RECORD DATE; OUTSTANDING SHARES
 
    Only stockholders of record at the close of business on November 24, 1997
(the "Record Date"), are entitled to receive notice of and to vote at the
meeting. The outstanding voting securities of the Company as of such date
consisted of 16,370,400 shares of Common Stock, $.01 par value. For information
regarding holders of more than 5% of the outstanding Common Stock, see "Election
of Directors--Securities Ownership of Certain Beneficial Owners and Management."
 
REVOCABILITY OF PROXIES
 
    The enclosed Proxy is revocable at any time before its use by delivering to
the Company a written notice of revocation or a duly executed proxy bearing a
later date. If a person who has executed and returned a proxy is present at the
meeting and wishes to vote in person, he or she may elect to do so and thereby
suspend the power of the proxy holders to vote his or her proxy.
 
VOTING AND SOLICITATION
 
    Every stockholder of record on the record date is entitled, for each share
held, to one vote on each proposal or item that comes before the meeting. In the
election of directors, each stockholder will be entitled to vote for six
nominees and the six nominees with the greatest number of votes will be elected.
 
    The cost of soliciting proxies will be borne by the Company. In addition,
the Company may reimburse brokerage firms and other persons representing
beneficial owners of shares for their expenses in forwarding solicitation
material to such beneficial owners. Proxies may also be solicited by certain of
the Company's directors, officers and regular employees, without additional
compensation personally or by telephone, telecopy, or telegram.
 
QUORUM; ABSTENTIONS; BROKER NON-VOTES
 
    The required quorum for the transaction of business at the Annual Meeting is
a majority of the shares of Common Stock issued and outstanding on the Record
Date. Shares that are voted "FOR," "AGAINST" or "WITHHELD FROM" a matter are
treated as being present at the meeting for purposes of establishing a quorum
and also treated as shares "represented and voting" at the Annual Meeting (the
"Votes Cast") with respect to such matter.
<PAGE>
    While there is no definitive statutory or case law authority in Delaware as
to the proper treatment of abstentions, the Company believes that abstentions
should be counted for purposes of determining both (i) the presence or absence
of the quorum for the transaction of business and (ii) the total number of Votes
Cast with respect to a proposal. In the absence of controlling president to the
contrary, the Company intends to treat abstentions in this manner. Accordingly,
abstentions will have the same effect as a vote against a proposal.
 
    Broker non-votes will be counted for purposes of determining the presence or
absence of a quorum for the transaction of business, but will not be counted for
purposes of determining the number of Votes Cast with respect to a proposal.
 
DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS
 
    Proposals of stockholders of the Company which are intended to be presented
by such stockholders at the Company's 1998 Annual Meeting must be received by
the Company no later than July 2, 1998 in order that they may be included in the
proxy statement and form of proxy relating to that meeting.
 
                             ELECTION OF DIRECTORS
 
GENERAL
 
    A Board of six directors is to be elected at the meeting. Unless otherwise
instructed, the proxy holders will vote all of the proxies received by them for
the Company's six nominees named below. In the event that any of the nominees
shall become unavailable, the proxy holders will vote in their discretion for a
substitute nominee. It is not expected that any nominee will be unavailable. The
term of office of each person elected as a director will continue until the next
Annual Meeting of Stockholders and until his successor has been elected and
qualified.
 
VOTE REQUIRED
 
    The six nominees receiving the highest number of affirmative votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote shall be elected to the Board of Directors. Votes withheld from any
director are counted for purposes of determining the presence or absence of a
quorum, but have no legal effect under Delaware law. THE BOARD OF DIRECTORS
RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE NOMINEES LISTED BELOW.

PERFORMANCE GRAPH
 
    The following graph compares the cumulative total return to stockholders,
assuming reinvestment of all dividends, of the Company's Common Stock since
February 11, 1993 (the date the Company first became subject to the reporting
requirements of the Exchange Act) to the cumulative total return over such
period of (i) the Standard & Poor's 500 Index and (ii) the Standard & Poor's
Medical Products & Supplies Index. The graph assumes that $100 was invested on
February 11, 1993 in the Common Stock of the Company and in each of the
comparative indices. The graph further assumes that such amount was initially
invested in the Common Stock of the Company at a price of $12.00 per share, the
price at which such stock was first offered to the public by the Company on that
date. The information contained in the Performance Graph shall not be deemed to
be "soliciting material" or to be "filed" with the Securities and Exchange
Commission, nor shall such information be incorporated by reference into any
future filing under the Securities Act or the Exchange Act, except to the extent
that the Company specifically incorporates it by reference into such filing.

(1) Total number of shares subject to options granted to employees in fiscal
    1997 was 1,893,388, which number includes options granted to employee
    directors.
 
(2) Potential realizable value is based on an assumption that the stock price
    appreciates at the annual rate shown (compounded annually) from the date of
    grant until the end of the ten-year option term. These numbers are
    calculated based on the requirements promulgated by the SEC and do not
    reflect the Company's estimate of future stock price growth.
 
(3) In November 1996, the Company repriced stock options that had an exercise
    price in excess of the fair market value in effect on the date of repricing.
    The option grants indicated reflect previously granted options that were
    repriced as if such options had been newly granted in November 1996.

REPORT ON EXECUTIVE COMPENSATION AND STOCK OPTION REPRICING
 
    The following Report of the Board of Directors describes the compensation
policies and rationale applicable to the Company's executive officers with
respect to the compensation paid to such executive officers for the year ended
June 30, 1997, as well as the Board's rationale for the stock option repricing
effected in late fiscal 1997. The information contained in the reports shall not
be deemed to be "soliciting material" or to be "filed" with the Securities and
Exchange Commission nor shall such information be incorporated by reference into
any previous or future filing under the Securities Act of 1933, as amended (the
"Securities Act") or the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), except to the extent that the Company specifically incorporates
it by reference into such filing.
 
    TO THE STOCKHOLDERS:
 
    The period beginning in mid-fiscal 1996 and running through fiscal 1997 was
a period year of substantial transition for Cyberonics which was reflected in
the actions taken with respect to executive compensation during the period. The
Company entered into fiscal 1997 with a compensation committee consisting of
only one outside director, Dr. Duerden. In mid year, Dr. Appel was added to the
Compensation Committee and, in June 1997, the Compensation Committee was
restructured, with Dr. Duerden dropping off and Mr. Coelho joining of the
Committee. Given the transitions facing the Company, as well as the transitions
on the Compensation Committee during fiscal 1997, the Board of Directors took
direct responsibility for executive compensation decisions during the year. The
Board of Directors expects the
 
                                       10
<PAGE>
Compensation Committee to resume normal responsibility for executive
compensation decisions going forward.
 
    The primary factor affecting the Company's executive compensation decisions
during fiscal 1997 was the acquisition agreement which the Company entered into
in April 1996 with St. Jude Medical, Inc. ("St. Jude"). That agreement gave St.
Jude the right, but not the obligation to acquire the Company. St. Jude's right
to acquire Cyberonics expired unexercised in October 1996. The acquisition
agreement with St. Jude provided that Cyberonics could not change the
compensation of its executive officers from the levels prevailing before the
agreement was entered into. Accordingly, through October 1996, executive
compensation was held at the levels established in fiscal 1996.
 
    Following expiration of St. Jude's option to acquire the Company, the Board
of Directors reviewed the compensation levels of the Company's executive
officers. While the agreement with St. Jude was in effect, significant momentum
had been built toward transitioning Cyberonics' employees, including most
executive officers, to St. Jude. In addition, during fiscal 1996, the Company
entered into agreements with its key employees, including executive officers,
which were designed to provide incentives for the contracting employees to stay
with Cyberonics through the acquisition and with the surviving entity following
the acquisition. When the acquisition option expired unexercised, the primary
concern of the Board of Directors was to keep the management team intact and
focused on pursuing the Company's key regulatory objectives.
 
    COMPENSATION POLICY
 
    The Company's executive compensation policies are designed to attract,
retain and motivate the highly skilled executive officers upon whose performance
the Company is dependent by providing compensation packages competitive with
those provided by similarly situated companies with whom the Company competes
for key employees. It is the Company's policy that compensation of executive
officers should include base compensation coupled with stock-based incentive
opportunities and cash bonuses. The Company does not contribute to any
retirement programs on behalf of any employees. Compensation levels for all
employees, including executive officers, are generally established for each
fiscal year near the beginning of the fiscal year.
 
    BASE SALARIES
 
    Base salaries for all employees are generally set at levels that are viewed
as competitive. Base salaries for fiscal 1997 were established at the beginning
of fiscal 1997, and generally reflected increases of 3% to 6% over fiscal 1996
levels. The level of increase for specific executive officers was determined by
comparing salaries paid by the Company with those paid by similarly situated
companies. In addition, in November 1996, executive compensation levels were
reviewed in light of expiration of St. Jude's option to acquire the Company and
the need to retain officers, many of whom were seeking or had secured
alternative employment in contemplation of the St. Jude transaction being
completed. As a result of this review, the base salary level of certain officers
was increased modestly.
 
    BONUSES
 
    The Company generally establishes target bonus levels for executive officers
at the same time that annual salary levels are established for the fiscal year.
For fiscal 1997, maximum bonus levels were set at 30% of base salary, the same
as fiscal 1996. Bonus payout is generally tied to a number of Company-wide
performance goals. Based upon Company performance during fiscal 1997, and in
particular the regulatory approvals achieved by the Company, executive officers
were paid 100% of their potential bonuses.
 
                                       11

    STOCK OPTION AWARDS
 
    Following expiration of the St. Jude option to acquire the Company, the
Board of Directors believed that it was critical to provide adequate long term
incentives for key employees, including executive officers, to remain with the
Company notwithstanding the uncertainty presented by expiration of the St. Jude
agreement. Accordingly, the Board evaluated the levels of options held by all
employees, and granted additional options to substantially all employees. With
respect to all employees (including executive officers), option grants were made
to bring employees to a level of option holdings based upon their functional
level within the Company. The same arrangement was made for executive officers
(other than Reese Terry who, because of his status as a founder and major
stockholder of the Company, received a lesser level of options).
 
    COMPENSATION OF CHIEF EXECUTIVE OFFICER
 
    Mr. Cummins became an executive officer of the Company in September 1995,
and entered into an Employment Agreement at that time. In April 1996, Mr.
Cummins' employment agreement was extended to run through December 31, 1996. At
the time Mr. Cummins became an executive officer of the Company, the Company was
contemplating effecting an acquisition or other similar transaction in the near
term. Accordingly, Mr. Cummins' compensation was structured primarily to reward
success of a change of control transaction. In particular, Mr. Cummins'
compensation package included a substantial bonus payout if a change of control
of the Company were accomplished within a specified period. Mr. Cummins base
salary ($150,000 per year) and option grant (50,000 shares) were set at
relatively modest levels for a chief executive officer given the narrow role he
was expected to play.
 
    In connection with the expiration of the St. Jude acquisition option, and
based upon Mr. Cummins' performance on behalf of the Company since becoming an
executive officer, the Board acknowledged that Mr. Cummins role had shifted from
a temporary, limited purpose role to that of a customary chief executive officer
with and indefinite employment period and full management responsibility.
Accordingly, it was determined that Mr. Cummins' compensation, and in particular
Mr. Cummins' option holdings should be adjusted to fully reflect the
responsibilities of his position. The Board accordingly increased Mr. Cummins'
base salary to $200,000 per year and granted Mr. Cummins an option to purchase
an additional 300,000 shares of Common Stock at an exercise price equal to the
fair market value as of the date of grant.
 
    REPRICING OF OPTIONS
 
    As indicated above, in November 1996 (shortly after St. Jude's option to
acquire Cyberonics expired), the Board of Directors met to review and take
action upon a number of compensation issues. One issue of concern to the Board
of Directors was the fact that the trading price of the Company's Common Stock
had decreased significantly following expiration of the St. Jude acquisition
option and, as a result, many employees including executive officers were
holding stock options with exercise prices that were higher than the prevailing
market price of the Company's Common Stock. As a result, these options were
failing to provide the long term incentive for which they were intended.
Moreover, given the uncertainty facing Cyberonics following expiration of the
St. Jude option, the Board of Directors believed that it was critically
important that the Company retain its employees, including its executive
officers. Accordingly, in November 1996, the Board elected to extend an offer to
all optionees (including executive officers and non-employee directors) holding
stock options with exercise prices higher than the prevailing market price for
shares of the Company's Common Stock ($3.06) the opportunity to reprice such
"underwater" options to $3.06 per share.
 
    Repriced options retained their original vesting provisions and term. As a
condition to the repricing, however, optionees agreed that the repriced options
would not be exercisable until the earlier of (i) December 31, 1997 or (ii) that
date on which the United States Food and Drug Administration
 
                                       12
<PAGE>
Advisory Panel recommends approval of the Company's then pending Pre-Market
Approval Application. (The FDA Advisory Panel recommended such approval on June
27, 1997.)
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    During fiscal 1997, compensation decisions were made by the entire Board of
Directors. Messrs. Cummins and Terry participated in deliberations regarding
compensation of executive officers but abstained from decisions relating to
their own compensation. No other member of the Company's Board of Directors has
previously served as an officer of the Company or any of its subsidiaries.
 
COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT
 
    Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
officers and directors, and persons who own more than ten percent of a
registered class of the Company's equity securities, to file reports of
ownership on Form 3 and changes in ownership on Form 4 or Form 5 with the
Securities and Exchange Commission (the "SEC"). Such officers, directors and
ten-percent stockholders are also required by SEC rules to furnish the Company
with copies of all Section 16(a) forms they file.
 
    Based solely on its review of the copies of such forms received by it, the
Company believes that, for the fiscal year ended June 30, 1997, all Section
16(a) filing requirements applicable to its officers, directors and ten-percent
stockholders were complied with.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Certain stockholders of the Company, including Messrs. Cummins and Terry,
Drs. Appel and Duffell and venture capital firms formerly affiliated with Mr.
Cummins, are entitled to certain registration rights with respect to the Common
Stock and certain stock options held by them.
 
    In March 1997, the Company sold an aggregate of 1,534,374 shares of its
Common Stock to a group of investors for $4.44 per share. The price of the
Common Stock was determined in arm's length negotiations between the Company and
the lead investor (which was not affiliated with the Company), and was based
largely upon the prevailing market price of the Company's Common Stock at the
time the terms of the financing were negotiated. Mr. Cummins, Dr. Appel, Dr.
Duffell and a family member of Mr. Lunney purchased an aggregate of 82,627
shares of Common Stock in such financing on the same terms as all other
investors.
 
    The Company's Bylaws provide that the Company is required to indemnify its
officers and directors to the fullest extent permitted by Delaware law,
including those circumstances in which indemnification would otherwise be
discretionary, and that the Company is required to advance expenses to its
officers and directors as incurred. Further, the Company has entered into
indemnification agreements with its officers and directors. The Company believes
that its charter and bylaw provisions and indemnification agreements are
necessary to attract and retain qualified persons as directors and officers.
 
    The Company believes that all of the transactions set forth above were made
on terms no less favorable to the Company than could have been obtained from
unaffiliated third parties. All future transactions between the Company and its
officers, directors, principal stockholders and affiliates will be approved by a
majority of the Board of Directors, including a majority of the independent and
disinterested outside directors on the Board of Directors, and will be on terms
no less favorable to the Company than could be obtained from unaffiliated third
parties.

                      PROPOSAL TO APPROVE 1997 STOCK PLAN
 
BACKGROUND
 
    In October 1997, the Board of Directors adopted the 1997 Stock Plan and
reserved 1,000,000 shares of Common Stock for issuance thereunder. The 1997
Stock Plan was adopted by the Board because it determined that the Company did
not have a sufficient number of shares available for issuance under the
Company's prior option plans. The Board of Directors is seeking stockholder
approval of the 1997 Stock Plan. In addition, as described below, the Company
has granted certain stock options SUBJECT TO STOCKHOLDER APPROVAL of the 1997
Stock Plan. Accordingly, a vote "FOR" approval of the 1997 Stock Plan also
constitutes approval of the option grants described below.
 
    Prior to adoption of this 1997 Stock Plan, the Company had the following
option plans in effect:
 
        The 1988 Incentive Stock Plan was adopted in 1988 and, as of October 31,
    1997, a total of 2,000,000 shares of Common Stock had been reserved for
    issuance under such Plan, of which options to purchase 703,699 shares had
    been exercised, options to purchase 1,261,702 shares were outstanding and
    34,599 shares were available for future grant.
 
        The 1996 Stock Option Plan was adopted in 1996 and, as of October 31,
    1997, a total of 2,000,000 shares of Common Stock had been reserved for
    issuance under such Plan, of which options to purchase 28,002 shares had
    been exercised, options to purchase 1,918,243 shares were outstanding and
    53,755 shares were available for grant.
 
    NEW PLAN BENEFITS.  The following table sets forth the number of options
that will be granted under the 1997 Stock Plan: (i) to the Named Executive
Officers; (ii) all executive officers as a group; (iii) all non-employee
directors as a group; and (iv) to all employees excluding executive officers:

    intention to do so, as described below, the Board of Directors has the
    discretion to grant additional options to the executive officers or to
    non-employee directors. To the extent that additional options are granted to
    executive officers or non-employee directors, the number of shares available
    for issuance to employees excluding executive officers would be reduced.

    In the Fall of 1997, the Compensation Committee of the Board of Directors
conducted a review of the stock options held by the Company's executive officers
and certain other senior employees. This review revealed that approximately 80%
of the options held by such persons were vested. The Compensation Committee
determined that, in order to retain the Company's officers and senior employees,
and provide them incentives to continue to contribute to the success of the
Company, it was necessary to grant such persons additional options. Accordingly,
in October 1997, the Company granted the stock options set forth in the
preceding table (the "October 1997 Options"). Each of the October 1997 Options
will vest ratably over a five-year period from the date of grant. The exercise
price of the October 1997 Options will be the closing price of the Company's
Common Stock as reported on the Nasdaq National Market on the day preceding the
date of the Company's Annual Meeting of Stockholders. The grant of the October
1997 Options is conditioned upon the stockholders approving the 1997 Stock Plan.
In the event that the stockholders do not approve such plan, the October 1997
Options will be void. The Compensation Committee and the Board of Directors as a
whole believes that approval of the 1997 Stock Plan (and implicit approval of
the October 1997 Options) is important to the Company and in the best interests
of the Company's stockholders.
 
    SECTION 162(m).  In 1993, Section 162(m) was added to the Internal Revenue
Code of 1986, as amended. Section 162(m) limits the Company's deduction in any
one fiscal year for federal income tax purposes to $1,000,000 per person with
respect to the Company's Chief Executive Officer and its four other highest paid
executive officers who are employed on the last day of the fiscal year unless
the compensation was not otherwise subject to the deduction limit. Grants under
the 1997 Stock Plan will not be subject to the deduction limitation if the
stockholders approve the 1997 Stock Plan, including the option grant limitations
described below.
 
    The approval of the adoption of the 1997 Stock Plan requires the affirmative
vote of the holders of a majority of the shares of the Company's Common Stock
represented, in person or by proxy, and voting at the Annual Meeting. THE
COMPENSATION COMMITTEE AND THE BOARD OF DIRECTORS AS A WHOLE RECOMMENDS THAT
STOCKHOLDERS VOTE "FOR" APPROVAL OF THE 1997 STOCK PLAN.
 
SUMMARY OF THE 1997 STOCK PLAN
 
    GENERAL.  The purpose of the 1997 Stock Plan is to attract and retain the
best available persons for positions of substantial responsibility with the
Company, to provide additional incentive to the employees, directors and
consultants of the Company and to promote the success of the Company's business.
Options granted under the 1997 Stock Plan may be either "incentive stock
options," as defined in Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code"), or non-statutory stock options. In addition, awards of, as
well as rights to purchase, shares of the Company's common stock ("Stock
Rights") may be granted under the 1997 Stock Plan.
 
    ADMINISTRATION.  The 1997 Stock Plan may generally be administered by the
Compensation Committee of the Board (the "Administrator"). Subject to the other
provisions of the 1997 Stock Plan, the Board has the authority to (i) interpret
the 1997 Stock Plan and apply its provisions; (ii) prescribe, amend or rescind
rules and regulations relating to the 1997 Stock Plan; (iii) select the persons
to whom options and Stock Rights are to be granted; (iv) determine the number of
shares to be made subject to each option or Stock Right; (v) reduce the exercise
price of any option to the then current fair market value; (vi) prescribe the
terms and conditions of each option or Stock Right; (vii) amend any outstanding
option or Stock Right, subject to applicable legal and 1997 Stock Plan
restrictions; (viii) authorize any person to execute, on behalf of the Company,
any instrument required to effect the grant of an option or Stock Right; and
(ix) take any other actions deemed necessary or advisable for the administration
of the 1997 Stock Plan. All decisions, interpretations and other actions of the
Administrator shall be final and binding on all holders of options and Stock
Rights and on all persons deriving their rights therefrom.
 
                                       15
<PAGE>
    ELIGIBILITY, LIMITATIONS.  Non-statutory stock options and Stock Rights may
be granted under the 1997 Stock Plan to employees, directors and consultants of
the Company or any parent or subsidiary of the Company. Incentive stock options
may be granted only to employees of the Company or any parent or subsidiary of
the Company.
 
    As discussed above, Section 162(m) of the Code places limits on the
deductibility for federal income tax purposes of compensation paid to certain
executive officers of the Company. In order to preserve the Company's ability to
deduct the compensation income associated with options granted to such persons,
the 1997 Stock Plan provides that no employee may be granted, in any fiscal year
of the Company, options to purchase more than 350,000 shares of common stock.
Notwithstanding this limit, however, in connection with an employee's initial
employment, he or she may be granted options to purchase up to an additional
50,000 shares of common stock.
 
    TERMS AND CONDITIONS OF OPTIONS.  Each option granted under the 1997 Stock
Plan 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) EXERCISE PRICE.  The Administrator determines the exercise price of
    options at the time the options are granted. The exercise of an incentive
    stock option may not be less than 100% of the fair market value of the
    common stock on the date such option is granted; provided, however, the
    exercise of an incentive stock option granted to a 10% stockholder may not
    be less than 110% of the fair market value of the common stock on the date
    such option is granted. The fair market value of the common stock is
    generally determined with reference to the closing sale price for the common
    stock (or the closing bid if no sales were reported) on the last market
    trading day prior to the date the option is granted. The exercise price of a
    non-statutory stock option may be determined by the Administrator, provided
    however, the exercise price of a non-statutory stock option intended to
    qualify as "performance-based compensation" within the meaning of Section
    162(m) of the Code may not be less than 100% of the fair market value of the
    common stock on the date of grant.
 
        (b) EXERCISE OF OPTION.  The Administrator determines when options
    become exercisable, and may in its discretion, accelerate the vesting of any
    outstanding option.
 
        (c) FORM OF CONSIDERATION.  The means of payment for shares issued upon
    exercise of an option is specified in each option agreement. The 1997 Stock
    Plan permits payment to be made by cash, check, promissory note, other
    shares of common stock of the Company (with some restrictions), cashless
    exercise, a reduction in the amount of any Company liability to the
    optionee, any other form of consideration permitted by applicable law, or
    any combination thereof.
 
        (d) TERM OF OPTION.  The term of an incentive stock option may be no
    more than ten years from the date of grant; provided that in the case of an
    incentive stock option granted to a 10% stockholder, the term of the option
    may be no more than five years from the date of grant. No option may be
    exercised after the expiration of its term.
 
        (e) TERMINATION OF EMPLOYMENT.  If an optionee's employment,
    directorship or consulting relationship terminates for any reason (other
    than death or disability), then all options held by the optionee under the
    1997 Stock Plan expire on the earlier of: (i) the date set forth in his or
    her notice of grant or stock option agreement; or (ii) the expiration date
    of such option. To the extent the option is exercisable at the time of such
    termination, the optionee may exercise all or part of his or her option at
    any time before its termination.
 
        (f) PERMANENT DISABILITY; DEATH.  If an optionee's employment,
    directorship or consulting relationship terminates as a result of permanent
    and total disability (as defined in the Code) or death, then all options
    held by such optionee under the 1997 Stock Plan will generally expire on the
    earlier of: (i) twelve months from the date of termination of optionee's
    employment; or (ii) the expiration date of the option. The optionee or, if
    applicable, the executor or other legal representative of the
 
                                       16
<PAGE>
    optionee's estate may exercise all or part of the optionee's option at any
    time before such expiration to the extent that such option was exercisable
    at the time of termination of employment.
 
        (g) NONTRANSFERABILITY OF OPTIONS.  Options granted under the 1997 Stock
    Plan generally are not transferable other than by will or the laws of
    descent and distribution, and generally may be exercised during the
    optionee's lifetime only by the optionee.
 
        (h) VALUE LIMITATION.  If the aggregate fair market value of all shares
    of common stock subject to an optionee's incentive stock option which are
    exercisable for the first time during any calendar year exceeds $100,000,
    the excess portion of such option will be treated as a non-statutory stock
    option.
 
        (i) OTHER PROVISIONS.  The stock option agreement may contain other
    terms, provisions and conditions not inconsistent with the 1997 Stock Plan
    as may be determined by the Administrator.
 
    STOCK RIGHTS.  A Stock Right may award the recipient common stock or may
give the recipient the right to purchase common stock. Shares received or
purchased pursuant to a Stock Right are subject to a restricted stock agreement
between the Company and the recipient. Unless the Administrator determines
otherwise, the restricted stock agreement shall give the Company a reacquisition
option exercisable upon the voluntary or involuntary termination of the
recipient's employment or consulting relationship with the Company for any
reason (including death and disability). The acquisition price for any shares
reacquired by the Company shall be the original price paid by the recipient, if
any. The reacquisition option lapses at a rate determined by the Administrator.
A Stock Right and the stock acquired pursuant thereto (while restricted) is
generally nontransferable other than by will or the laws of descent and
distribution.
 
    ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  In the event that the stock of
the Company changes by reason of any stock split, reverse stock split, stock
dividend, combination, reclassification or other similar changes in the capital
structure of the Company effected without the receipt of consideration,
appropriate adjustments will be made in the number and class of shares of stock
subject to the 1997 Stock Plan, the number and class of shares of stock subject
to any option or Stock Right outstanding under the 1997 Stock Plan, and the
exercise price of any such award. In the event of a liquidation or dissolution,
any unexercised options will terminate. The Administrator may, in its
discretion, provide that each optionee will fully vest in and have the right to
exercise the optionee's option or Stock Right as to all of the optioned stock,
and shall release all restrictions on any restricted stock prior to the
consummation of the liquidation or dissolution.
 
    In connection with any merger, consolidation, acquisition of assets or like
occurrence involving the Company that is not a change of control, each
outstanding option or Stock Right shall be assumed or an equivalent option or
right substituted by the successor corporation. If the successor corporation
refuses to assume the options or Stock Rights or to substitute substantially
equivalent options or rights, the optionee shall fully vest in and have the
right to exercise the option or Stock Right as to all of the optioned stock and
any restrictions shall lapse with respect to restricted stock. In such event,
the Administrator shall notify the optionee that the option or Stock Right is
fully vested and exercisable for fifteen (15) days from the date of such notice,
that the option or Stock Right shall terminate upon expiration of such period,
and that all restrictions have lapsed with respect to their restricted shares.
 
    In connection with any change of control of the Company, the optionee shall
fully vest in and have the right to exercise the optionee's options or Stock
Rights as to all of the optioned stock, and any restrictions shall lapse with
respect to any unreleased restricted stock. In such event, the Administrator
shall notify the optionee that the option or Stock Right is fully vested and
exercisable for fifteen (15) days from the date of such notice, that the option
or Stock Purchase Right shall terminate upon expiration of such period, and that
restrictions have been released on restricted shares. A change of control is
defined to include certain mergers, asset sales, or consolidations, the
acquisition of more than fifty percent (50%) of the Company by any person or
certain changes in the composition of the Board of Directors.
 
                                       17
<PAGE>
    AMENDMENT AND TERMINATION OF THE 1997 STOCK PLAN.  The Board may amend,
alter, suspend or terminate the 1997 Stock Plan, or any part thereof, at any
time and for any reason. No such action by the Board or stockholders may alter
or impair any option or Stock Right previously granted under the 1997 Stock Plan
without the written consent of the optionee/recipient. Unless terminated
earlier, the 1997 Stock Plan will terminate ten years from the date of its
approval by the stockholders or the Board, whichever is earlier.
 
FEDERAL INCOME TAX CONSEQUENCES
 
    INCENTIVE STOCK OPTIONS.  An optionee who is granted an incentive stock
option does not generally recognize taxable income at the time the option is
granted or upon its exercise, although the exercise may subject the optionee to
the alternative minimum tax. Upon a disposition of the shares more than two
years after grant of the option and one year after exercise of the option, any
gain or loss is treated as long-term capital gain or loss. If these holding
periods are not satisfied, the optionee recognizes ordinary income at the time
of disposition equal to the difference between the exercise price and the lower
of (i) the fair market value of the shares at the date of the option exercise or
(ii) the sale price of the shares. Any gain or loss recognized on such a
premature disposition of the shares in excess of the amount treated as ordinary
income is treated as long-term or short-term capital gain or loss, depending on
the holding period. A different rule for measuring ordinary income upon such a
premature disposition may apply if the optionee is an officer, director, or 10%
stockholder of the Company. The Company is entitled to a deduction in the same
amount as the ordinary income recognized by the optionee.
 
    NON-STATUTORY STOCK OPTIONS.  An optionee does not recognize any taxable
income at the time he or she is granted a non-statutory stock option. Upon
exercise, the optionee recognizes taxable income generally by the excess of the
then fair market value of the shares over the exercise price. Any taxable income
recognized in connection with an option exercise by an employee of the Company
is subject to tax withholding by the Company. The Company is entitled to a
deduction in the same amount as the ordinary income recognized by the optionee.
Upon a disposition of such shares by the optionee, any difference between the
sale price and the optionee's exercise price, to the extent not recognized as
taxable income as provided above, is treated as long-term or short-term capital
gain or loss, depending on the holding period.
 
    STOCK RIGHTS.  Restricted stock is generally acquired pursuant to Stock
Rights. At the time of acquisition, restricted stock is subject to a
"substantial risk of forfeiture" within the meaning of Section 83 of the Code.
As a result, the recipient will not generally recognize ordinary income at the
time of acquisition. Instead, the recipient will recognize ordinary income on
the dates when the stock ceases to be subject to a substantial risk of
forfeiture. The stock will generally cease to be subject to a substantial risk
of forfeiture when it is no longer subject to the Company's right to reacquire
the stock upon the recipient's termination of employment with the Company. At
such times, the recipient will recognize ordinary income measured as the
difference between the purchase price (if any) and the fair market value of the
stock on the date the stock is no longer subject to a substantial risk of
forfeiture.
 
    The purchaser may accelerate to the date of acquisition his or her
recognition of ordinary income, if any, and the beginning of any capital gain
holding period, by timely filing an election pursuant to Section 83(b) of the
Code. In such event, the ordinary income recognized, if any, is measured as the
difference between the purchase price and the fair market value of the stock on
the date of purchase and the capital gain holding period commences on such date.
The ordinary income recognized by a purchaser who is an employee will be subject
to tax withholding by the Company. Different rules may apply if the purchaser is
also an officer, director, or 10% stockholder of the Company.
 
    THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME TAXATION
UPON OPTIONEES AND THE COMPANY WITH RESPECT TO THE GRANT AND EXERCISE OF
OPTIONS, AND UPON RECIPIENTS OF STOCK RIGHTS, UNDER THE 1997 STOCK PLAN. IT DOES
NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE TAX CONSEQUENCES OF THE

               (i)    MULTIPLE ADMINISTRATIVE BODIES.  The Plan may be 
administered by different Committees with respect to different groups of 
Service Providers.

               (ii)   SECTION 162(m). To the extent that the Administrator 
determines it to be desirable to qualify Options granted hereunder as 
"performance-based compensation" within the meaning of Section 162(m) of the 
Code, the Plan shall be administered by a Committee of two or more "outside 
directors" within the meaning of Section 162(m) of the Code.

               (iii)  RULE 16b-3.  To the extent desirable to qualify 
transactions hereunder as exempt under Rule 16b-3, the transactions 
contemplated hereunder shall be structured to satisfy the requirements for 
exemption under Rule 16b-3.

               (iv)   OTHER ADMINISTRATION.  Other than as provided above, 
the Plan shall be administered by (A) the Board or (B) a Committee, which 
committee shall be constituted to satisfy Applicable Laws. 

          (b)  POWERS OF THE ADMINISTRATOR.  Subject to the provisions of the 
Plan, and in the case of a Committee, subject to the specific duties 
delegated by the Board to such Committee, the Administrator shall have the 
authority, in its discretion:

               (i)    to determine the Fair Market Value;

               (ii)   to select the Service Providers to whom Options and 
Stock Rights may be granted hereunder;


                                   A-4

<PAGE>

               (iii)   to determine the number of shares of Common Stock to 
be covered by each Option and Stock Right granted hereunder;

               (iv)    to approve forms of agreement for use under the Plan;

               (v)     to determine the terms and conditions, not 
inconsistent with the terms of the Plan, of any Option or Stock Right granted 
hereunder.  Such terms and conditions include, but are not limited to, the 
exercise price, the time or times when Options or Stock Rights may be 
exercised (which may be based on performance criteria), any vesting 
acceleration or waiver of forfeiture restrictions, and any restriction or 
limitation regarding any Option or Stock Right of the shares of Common Stock 
relating thereto, based in each case on such factors as the Administrator, in 
its sole discretion, shall determine;

               (vi)     to reduce the exercise price of any Option or Stock 
Right to the then current Fair Market Value if the Fair Market Value of the 
Common Stock covered by such Option or Stock Right shall have declined since 
the date the Option or Stock Right was granted;

               (vii)     to institute an Option Exchange Program;

               (viii)    to construe and interpret the terms of the Plan and 
awards granted pursuant to the Plan;

               (ix)      to prescribe, amend and rescind rules and 
regulations relating to the Plan, including rules and regulations relating to 
sub-plans established for the purpose of qualifying for preferred tax 
treatment under foreign tax laws;

               (x)       to modify or amend each Option or Stock Right 
(subject to Section 15(c) of the Plan), including the discretionary authority 
to extend the post-termination exercisability period of Options longer than 
is otherwise provided for in the Plan;

               (xi)      to allow Optionees to satisfy withholding tax 
obligations by electing to have the Company withhold from the Shares to be 
issued upon exercise of an Option or Stock Right that number of Shares having 
a Fair Market Value equal to the amount required to be withheld.  The Fair 
Market Value of the Shares to be withheld shall be determined on the date 
that the amount of tax to be withheld is to be determined.  All elections by 
an Optionee to have Shares withheld for this purpose shall be made in such 
form and under such conditions as the Administrator may deem necessary or 
advisable;

               (xii)     to authorize any person to execute on behalf of the 
Company any instrument required to effect the grant of an Option or Stock 
Right previously granted by the Administrator;

               (xiii)    to make all other determinations deemed necessary or 
advisable for administering the Plan.


                                   A-5

<PAGE>

          (c)  EFFECT OF ADMINISTRATOR'S DECISION.  The Administrator's 
decisions, determinations and interpretations shall be final and binding on 
all Optionees and any other holders of Options or Stock Rights.

     5.   ELIGIBILITY.  Nonstatutory Stock Options and Stock Rights
may be granted to Service Providers.  Incentive Stock Options may be
granted only to Employees.

     6.   LIMITATIONS.

          (a)  Each Option shall be designated in the Option Agreement
as either an Incentive Stock Option or a Nonstatutory Stock Option. 
However, notwithstanding such designation, to the extent that the
aggregate Fair Market Value of the Shares with respect to which
Incentive Stock Options are exercisable for the first time by the
Optionee during any calendar year (under all plans of the Company and
any Parent or Subsidiary) exceeds $100,000, such Options shall be
treated as Nonstatutory Stock Options.  For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in
the order in which they were granted.  The Fair Market Value of the
Shares shall be determined as of the time the Option with respect to
such Shares is granted.

          (b)  Neither the Plan nor any Option or Stock Right shall
confer upon an Optionee any right with respect to continuing the
Optionee's relationship as a Service Provider with the Company, nor
shall they interfere in any way with the Optionee's right or the
Company's right to terminate such relationship at any time, with or
without cause.

          (c)  The following limitations shall apply to grants of
Options:

               (i)     No Service Provider shall be granted, in any fiscal 
year of the Company, Options to purchase more than 250,000 Shares.

               (ii)     In connection with his or her initial service, a 
Service Provider may be granted Options to purchase up to an additional 
250,000 Shares which shall not count against the limit set forth in 
subsection (i) above.

               (iii)     The foregoing limitations shall be adjusted 
proportionately in connection with any change in the Company's capitalization 
as described in Section 13. 

               (iv)     If an Option is cancelled in the same fiscal year of 
the Company in which it was granted (other than in connection with a 
transaction described in Section 13), the cancelled Option will be counted 
against the limits set forth in subsections (i) and (ii) above.  For this 
purpose, if the exercise price of an Option is reduced, the transaction will 
be treated as a cancellation of the Option and the grant of a new Option.

     7.   TERM OF PLAN.  Subject to Section 19 of the Plan, the Plan shall 
become effective upon its adoption by the Board.  It shall continue in effect 
for a term of ten (10) years unless terminated earlier under Section 15 of 
the Plan.


                                      A-6
<PAGE>

     8.   TERM OF OPTION.  The term of each Option shall be stated in the 
Option Agreement.  In the case of an Incentive Stock Option, the term shall 
be ten (10) years from the date of grant or such shorter term as may be 
provided in the Option Agreement.  Moreover, in the case of an Incentive 
Stock Option granted to an Optionee who, at the time the Incentive Stock 
Option is granted, owns stock representing more than ten percent (10%) of the 
total combined voting power of all classes of stock of the Company or any 
Parent or Subsidiary, the term of the Incentive Stock Option shall be five 
(5) years from the date of grant or such shorter term as may be provided in 
the Option Agreement.

     9.   OPTION EXERCISE PRICE AND CONSIDERATION.

          (a)  EXERCISE PRICE.  The per share exercise price for the Shares 
to be issued pursuant to exercise of an Option shall be determined by the 
Administrator, subject to the following:

               (i)    In the case of an Incentive Stock Option

                      (A)  granted to an Employee who, at the time the 
Incentive Stock Option is granted, owns stock representing more than ten 
percent (10%) of the voting power of all classes of stock of the Company or 
any Parent or Subsidiary, the per Share exercise price shall be no less than 
110% of the Fair Market Value per Share on the date of grant.

                      (B)  granted to any Employee other than an Employee 
described in paragraph (A) immediately above, the per Share exercise price 
shall be no less than 100% of the Fair Market Value per Share on the date of 
grant.

               (ii)    In the case of a Nonstatutory Stock Option, the per 
Share exercise price shall be determined by the Administrator. In the case of 
a Nonstatutory Stock Option intended to qualify as "performance-based 
compensation" within the meaning of Section 162(m) of the Code, the per Share 
exercise price shall be no less than 100% of the Fair Market Value per Share 
on the date of grant.

               (iii)    Notwithstanding the foregoing, Options may be granted 
with a per Share exercise price of less than 100% of the Fair Market Value 
per Share on the date of grant pursuant to a merger or other corporate 
transaction.

          (b)  WAITING PERIOD AND EXERCISE DATES.  At the time an Option is 
granted, the Administrator shall fix the period within which the Option may 
be exercised and shall determine any conditions which must be satisfied 
before the Option may be exercised. 

          (c)  FORM OF CONSIDERATION.  The Administrator shall determine the 
acceptable form of consideration for exercising an Option, including the 
method of payment.  In the case of an Incentive Stock Option, the 
Administrator shall determine the acceptable form of consideration at the 
time of grant.  Such consideration may consist entirely of:

               (i)     cash;



                                      A-7

<PAGE>

               (ii)    check;

               (iii)   promissory note;

               (iv)    other Shares which (A) in the case of Shares acquired 
upon exercise of an option, have been owned by the Optionee for more than six 
months on the date of surrender, and (B) have 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;

               (v)     consideration received by the Company under a cashless 
exercise program implemented by the Company in connection with the Plan;

               (vi)    a reduction in the amount of any Company liability to 
the Optionee, including any liability attributable to the Optionee's 
participation in any Company-sponsored deferred compensation program or 
arrangement;

               (vii)   any combination of the foregoing methods of payment; or

               (viii)  such other consideration and method of payment for the 
issuance of Shares to the extent permitted by Applicable Laws.

     10.  EXERCISE OF OPTION.

          (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option 
granted hereunder shall be exercisable according to the terms of the Plan and 
at such times and under such conditions as determined by the Administrator 
and set forth in the Option Agreement.  Unless the Administrator provides 
otherwise, vesting of Options granted hereunder shall be tolled during any 
unpaid leave of absence.  An Option may not be exercised for a fraction of a 
Share.

               An Option shall be deemed exercised when the Company receives: 
(i) written or electronic notice of exercise (in accordance with the Option 
Agreement) from the person entitled to exercise the Option, and (ii) full 
payment for the Shares with respect to which the Option is exercised.  Full 
payment may consist of any consideration and method of payment authorized by 
the Administrator and permitted by the Option Agreement and the Plan.  Shares 
issued upon exercise of an Option shall be issued in the name of the Optionee 
or, if requested by the Optionee, in the name of the Optionee and his or her 
spouse. Until the Shares are issued (as evidenced by the appropriate entry on 
the books of the Company or of a duly authorized transfer agent of the 
Company), no right to vote or receive dividends or any other rights as a 
shareholder shall exist with respect to the Optioned Stock, notwithstanding 
the exercise of the Option.  The Company shall issue (or cause to be issued) 
such Shares promptly after the Option is exercised.  No adjustment will be 
made for a dividend or other right for which the record date is prior to the 
date the Shares are issued, except as provided in Section 13 of the Plan.



                                        A-8

<PAGE>

               Exercising an Option in any manner shall decrease the number 
of Shares thereafter 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.

          (b)  TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER.  If an 
Optionee ceases to be a Service Provider, other than upon the Optionee's 
death or Disability, the Optionee may exercise his or her Option within such 
period of time as is specified in the Option Agreement to the extent that the 
Option is vested on the date of termination (but in no event later than the 
expiration of the term of such Option as set forth in the Option Agreement).  
In the absence of a specified time in the Option Agreement, the Option shall 
remain exercisable for three (3) months following the Optionee's termination. 
If, on the date of termination, the Optionee is not vested as to his or her 
entire Option, the Shares covered by the unvested portion of the Option shall 
revert to the Plan.  If, after termination, the Optionee does not exercise 
his or her Option within the time specified by the Administrator, the Option 
shall terminate, and the Shares covered by such Option shall revert to the 
Plan.

          (c)  DISABILITY OF OPTIONEE.  If an Optionee ceases to be a Service 
Provider as a result of the Optionee's Disability, the Optionee may exercise 
his or her Option within such period of time as is specified in the Option 
Agreement to the extent the Option is vested on the date of termination (but 
in no event later than the expiration of the term of such Option as set forth 
in the Option Agreement).  In the absence of a specified time in the Option 
Agreement, the Option shall remain exercisable for twelve (12) months 
following the Optionee's termination.  If, on the date of termination, the 
Optionee is not vested as to his or her entire Option, the Shares covered by 
the unvested portion of the Option shall revert to the Plan.  If, after 
termination, the Optionee does not exercise his or her Option within the time 
specified herein, the Option shall terminate, and the Shares covered by such 
Option shall revert to the Plan.

          (d)  DEATH OF OPTIONEE.  If an Optionee dies while a Service 
Provider, the Option may be exercised within such period of time as is 
specified in the Option Agreement (but in no event later than the expiration 
of the term of such Option as set forth in the Notice of Grant), by the 
Optionee's estate or by a person who acquires the right to exercise the 
Option by bequest or inheritance, but only to the extent that the Option is 
vested on the date of death.  In the absence of a specified time in the 
Option Agreement, the Option shall remain exercisable for twelve (12) months 
following the Optionee's termination.  If, at the time of death, the Optionee 
is not vested as to his or her entire Option, the Shares covered by the 
unvested portion of the Option shall immediately revert to the Plan.  The 
Option may be exercised by the executor or administrator of the Optionee's 
estate or, if none, by the person(s) entitled to exercise the Option under 
the Optionee's will or the laws of descent or distribution.  If the Option is 
not so exercised within the time specified herein, the Option shall 
terminate, and the Shares covered by such Option shall revert to the Plan.

          (e)  BUYOUT PROVISIONS.  The Administrator may at any time offer to 
buy out for a payment in cash or Shares an Option previously granted based on 
such terms and conditions as the Administrator shall establish and 
communicate to the Optionee at the time that such offer is made.



                                     A-9

     11.  STOCK RIGHTS.

          (a)  GRANT.  Stock Rights may be issued either alone, in addition 
to, or in tandem with other awards granted under the Plan and/or cash awards 
made outside of the Plan.  After the Administrator determines that it will 
offer Stock Rights under the Plan, it shall advise the offeree in writing or 
electronically, by means of a Notice of Grant, of the terms, conditions and 
restrictions related to the offer, including the number of Shares subject to 
the Stock Right, the price to be paid (if any), and the time within which the 
offeree must accept such offer.  The offer shall be accepted by execution of 
a Restricted Stock Agreement in such form as is determined by the 
Administrator.

          (b)  REACQUISITION OPTION.  Unless the Administrator determines 
otherwise, the Restricted Stock Agreement shall grant the Company a 
reacquisition option exercisable upon the voluntary or involuntary 
termination of the recipient's status as a Service Provider for any reason 
(including death or Disability) .  The reacquisition price (if any) for 
Shares reacquired pursuant to the Restricted Stock Agreement shall be 
determined by the Administrator and may be paid by cancellation of any 
indebtedness of the recipient to the Company.  The reacquisition option shall 
lapse at a rate determined by the Administrator.

          (c)  OTHER PROVISIONS.  The Restricted Stock Agreement shall 
contain such other terms, provisions and conditions not inconsistent with the 
Plan as may be determined by the Administrator in its sole discretion. 

          (d)  RIGHTS AS A SHAREHOLDER.  Once Restricted Stock is acquired 
pursuant to a Stock Right, the recipient shall have rights equivalent to 
those of a shareholder, and shall be a shareholder when his or her 
acquisition is entered upon the records of the duly authorized transfer agent 
of the Company.  No adjustment will be made for a dividend or other right for 
which the record date is prior to the date of issuance of Common Stock 
pursuant to a Stock Right, except as provided in Section 13 of the Plan.

     12.  NON-TRANSFERABILITY OF OPTIONS AND STOCK RIGHTS.  Unless determined 
otherwise by the Administrator, an Option or Stock Right may not be sold, 
pledged, assigned, hypothecated, transferred, or disposed of in any manner 
other than by will or by the laws of descent or distribution and may be 
exercised, during the lifetime of the Optionee, only by the Optionee.  If the 
Administrator makes an Option or Stock Right transferable, such Option or 
Stock Right shall contain such additional terms and conditions as the 
Administrator deems appropriate.

     13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION,
MERGER OR ASSET SALE. 

          (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by 
the shareholders of the Company, the number of shares of Common Stock covered 
by each outstanding Option and Stock Right, and the number of shares of 
Common Stock which have been authorized for issuance under the Plan but as to 
which no Options or Stock Rights have yet been granted or which have been 
returned to the Plan upon cancellation or expiration of an Option or Stock 
Right, as well as the price per share of Common Stock covered by each such 
outstanding Option or Stock Right, shall be proportionately adjusted for any 
increase or decrease in the number of issued shares of Common Stock resulting 
from a 


                                      A-10

<PAGE>

stock split, reverse stock split, stock dividend, combination or 
reclassification of the Common Stock, or any other increase or decrease in 
the number of issued shares of Common Stock effected without receipt of 
consideration by the Company; provided, however, that conversion of any 
convertible securities of the Company shall not be deemed to have been 
"effected without receipt of consideration."  Such adjustment shall be made 
by the Board, whose determination in that respect shall be final, binding and 
conclusive. Except as expressly provided herein, no issuance 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 of Common Stock 
subject to an Option or Stock Right.

          (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed 
dissolution or liquidation of the Company, the Administrator shall notify 
each Optionee as soon as practicable prior to the effective date of such 
proposed transaction.  The Administrator in its discretion may provide for an 
Optionee to have the right to exercise his or her Option until fifteen (15) 
days prior to such transaction as to all of the Optioned Stock covered 
thereby, including Shares as to which the Option would not otherwise be 
exercisable.  In addition, the Administrator may provide that any Company 
reacquisition option applicable to any Shares acquired upon exercise of an 
Option or Stock Right shall lapse as to all such Shares, provided the 
proposed dissolution or liquidation takes place at the time and in the manner 
contemplated.  To the extent it has not been previously exercised, an Option 
or Stock Right will terminate immediately prior to the consummation of such 
proposed action.

          (c)  MERGER OR ASSET SALE.  Subject to Section 13(d), in the event 
of a merger of the Company with or into another corporation, or the sale of 
substantially all of the assets of the Company, each outstanding Option and 
Stock Right shall be assumed or an equivalent option or right substituted by 
the successor corporation or a Parent or Subsidiary of the successor 
corporation.  In the event that the successor corporation refuses to assume 
or substitute for the Option or Stock Right, the Optionee shall fully vest in 
and have the right to exercise the Option or Stock Right as to all of the 
Optioned Stock, including Shares as to which it would not otherwise be vested 
or exercisable, and any Company reacquisition option applicable to any Shares 
acquired upon exercise of an Option or Stock Right shall lapse as to all such 
Shares.  If an Option or Stock Right becomes fully vested and exercisable in 
lieu of assumption or substitution in the event of a merger or sale of 
assets, the Administrator shall notify the Optionee in writing or 
electronically that the Option or Stock Right shall be fully vested and 
exercisable for a period of fifteen (15) days from the date of such notice, 
and the Option or Stock Right shall terminate upon the expiration of such 
period.  For the purposes of this paragraph, the Option or Stock Right shall 
be considered assumed if, following the merger or sale of assets, the option 
or right confers the right to purchase or receive, for each Share of Optioned 
Stock subject to the Option or Stock Right immediately prior to the merger or 
sale of assets, the consideration (whether stock, cash, or other securities 
or property) received in the merger or sale of assets by holders of Common 
Stock for each Share held on the effective date of the transaction (and if 
holders were offered a choice of consideration, the type of consideration 
chosen by the holders of a majority of the outstanding Shares); provided, 
however, that if such consideration received in the merger or sale of assets 
is not solely common stock of the successor corporation or its Parent, the 
Administrator may, with the consent of the successor corporation, provide for 
the consideration to be received upon the exercise of the Option or Stock 
Right, for each Share of Optioned Stock subject to the Option or Stock Right, 
to be solely common stock of 


                                       A-11

<PAGE>

the successor corporation or its Parent equal in fair market value to the per 
share consideration received by holders of Common Stock in the merger or sale 
of assets.

          (d)  CHANGE OF CONTROL.  In the event of a Change of Control (as 
defined below), the Optionee shall fully vest in and have the right to 
exercise the Option or Stock Right as to all of the Optioned Stock, including 
Shares as to which it would not otherwise be vested or exercisable, and any 
Company reacquisition option applicable to any Shares acquired upon exercise 
of an Option or Stock Right shall lapse as to all such Shares.  If an Option 
or Stock Right becomes fully vested and exercisable as the result of a Change 
of Control, the Administrator shall notify the Optionee in writing or 
electronically prior to the Change of Control that the Option or Stock Right 
shall be fully vested and exercisable for a period of fifteen (15) days from 
the date of such notice, and the Option or Stock Right shall terminate upon 
the expiration of such period.  For purposes of this Plan, a "Change of 
Control" means the happening of any of the following events:

                (i)    When any "person," as such term is used in Sections 
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the 
"Exchange Act"), other than the Company, a subsidiary of the Company or a 
Company employee benefit plan, including any trustee of such plan acting as 
trustee, is or becomes the "beneficial owner" (as defined in Rule 13d-3 under 
the Exchange Act), directly or indirectly, of securities of the Company 
representing fifty percent (50%) or more of the combined voting power of the 
Company's then outstanding securities entitled to vote generally in the 
election of directors; or

                (ii)    The shareholders of the Company approve a merger or 
consolidation of the Company with any other corporation, other than a merger 
or consolidation which would result in the voting securities of the Company 
outstanding immediately prior thereto continuing to represent (either by 
remaining outstanding or by being converted into voting securities of the 
surviving entity) more than fifty percent (50%) of the total voting power 
represented by the voting securities of the Company or such surviving entity 
outstanding immediately after such merger or consolidation, or the 
shareholders of the Company approve an agreement for the sale or disposition 
by the Company of all or substantially all the Company's assets; or

                (iii)    A change in the composition of the Board of 
Directors of the Company, as a result of which fewer than a majority of the 
directors are Incumbent Directors.  "Incumbent Directors" shall mean 
directors who either (A) are directors of the Company as of the date the Plan 
is approved by the shareholders, or (B) are elected, or nominated for 
election, to the Board of Directors of the Company with the affirmative votes 
of at least a majority of the Incumbent Directors at the time of such 
election or nomination (but shall not include an individual whose election or 
nomination is in connection with an actual or threatened proxy contest 
relating to the election of directors to the Company).

     14.  DATE OF GRANT.  The date of grant of an Option or Stock Right shall 
be, for all purposes, the date on which the Administrator makes the 
determination granting such Option or Stock Right, or such other later date 
as is determined by the Administrator.  Notice of the determination shall be 
provided to each Optionee within a reasonable time after the date of such 
grant.

     15.  AMENDMENT AND TERMINATION OF THE PLAN.

          (a)  AMENDMENT AND TERMINATION.  The Board may at any time amend, 
alter, suspend or terminate the Plan.  

          (b)  SHAREHOLDER APPROVAL.  The Company shall obtain shareholder 
approval of any Plan amendment to the extent necessary and desirable to 
comply with Applicable Laws. 

          (c)  EFFECT OF AMENDMENT OR TERMINATION.  No amendment, alteration, 
suspension or termination of the Plan shall impair the rights of any 
Optionee, unless mutually agreed otherwise between the Optionee and the 
Administrator, which agreement must be in writing and signed by the Optionee 
and the Company.  Termination of the Plan shall not affect the 
Administrator's ability to exercise the powers granted to it hereunder with 
respect to Options granted under the Plan prior to the date of such 
termination.

     16.  CONDITIONS UPON ISSUANCE OF SHARES.  

          (a)  LEGAL COMPLIANCE.  Shares shall not be issued pursuant to the 
exercise of an Option or Stock Right unless the exercise of such Option or 
Stock Right and the issuance and delivery of such Shares shall comply with 
Applicable Laws and shall be further subject to the approval of counsel for 
the Company with respect to such compliance.

          (b)  INVESTMENT REPRESENTATIONS.  As a condition to the exercise of 
an Option or Stock Right, the Company may require the person exercising such 
Option or Stock Right to represent and warrant at the time of any such 
exercise that the Shares are being acquired only for investment and without 
any present intention to sell or distribute such Shares if, in the opinion of 
counsel for the Company, such a representation is required.

     17.  INABILITY TO OBTAIN AUTHORITY.  The inability of the Company to 
obtain authority from any regulatory body having jurisdiction, which 
authority is deemed by the Company's counsel to be necessary to the lawful 
issuance and sale of any Shares hereunder, shall relieve the Company of any 
liability in respect of the failure to issue or sell such Shares as to which 
such requisite authority shall not have been obtained.

     18.  RESERVATION OF SHARES.  The Company, during the term of this Plan, 
will at all times reserve and keep available such number of Shares as shall 
be sufficient to satisfy the requirements of the Plan.

     19.  SHAREHOLDER APPROVAL.  The Plan shall be subject to approval by the 
shareholders of the Company within twelve (12) months after the date the Plan 
is adopted.  Such shareholder approval shall be obtained in the manner and to 
the degree required under Applicable Laws.

                                             event shall this Option be
                                             exercised later than the
                                             Term/Expiration Date as
                                             provided above.

II.  AGREEMENT

     1.   GRANT OF OPTION.  The Plan Administrator of the Company hereby 
grants to the Optionee named in the Notice of Grant attached as Part I of 
this Agreement (the "Optionee") an option (the "Option") to purchase the 
number of Shares, as set forth in the Notice of Grant, at the exercise price 
per share set forth in the Notice of Grant (the "Exercise Price"), subject to 
the terms and conditions of the Plan, which is incorporated herein by 
reference.  Subject to Section 15(c) of the Plan, in the event of a conflict 
between the terms and conditions of the Plan and the terms and conditions of 
this Option Agreement, the terms and conditions of the Plan shall prevail.

If designated in the Notice of Grant as an Incentive Stock Option ("ISO"), 
this Option is intended to qualify as an Incentive Stock Option under Section 
422 of the Code.  However, if this Option is intended to be an Incentive 
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section 
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

     2.   EXERCISE OF OPTION.

          (a)  RIGHT TO EXERCISE.  This Option is exercisable during its term 
in accordance with the Vesting Schedule set out in the Notice of Grant and 
the applicable provisions of the Plan and this Option Agreement.

          (b)  METHOD OF EXERCISE.  This Option is exercisable by delivery of 
an exercise notice, in the form attached as Exhibit A (the "Exercise 
Notice"), which shall state the election to exercise the Option, the number 
of Shares in respect of which the Option is being exercised (the "Exercised 
Shares"), and such other representations and agreements as may be required by 
the Company pursuant to the provisions of the Plan.  The Exercise Notice 
shall be completed by the Optionee and delivered to the Director of Corporate 
Compliance or to the Secretary of the Company.  The Exercise Notice shall be 
accompanied by payment of the aggregate Exercise Price as to all Exercised 
Shares.  This Option shall be deemed to be exercised upon receipt by the 
Company of such fully executed Exercise Notice accompanied by such aggregate 
Exercise Price.

     No Shares shall be issued pursuant to the exercise of this Option unless 
such issuance and exercise complies with Applicable Laws. Assuming such 
compliance, for income tax purposes the Exercised Shares shall be considered 
transferred to the Optionee on the date the Option is exercised with respect 
to such Exercised Shares.

     3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall 
be by any of the following, or a combination thereof, at the election of the 
Optionee:

          (a)  cash; or


                                      B-2

<PAGE>

          (b)  check; or

          (c)  consideration received by the Company under a cashless 
exercise program implemented by the Company in connection with the Plan; or 

          (d)  surrender of other Shares which (i) in the case of Shares 
acquired upon exercise of an option, have been owned by the Optionee for more 
than six (6) months on the date of surrender, and (ii) have a Fair Market 
Value on the date of surrender equal to the aggregate Exercise Price of the 
Exercised Shares; or

     4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred 
in any manner otherwise than by will or by the laws of descent or 
distribution and may be exercised during the lifetime of Optionee only by the 
Optionee.  The terms of the Plan and this Option Agreement shall be binding 
upon the executors, administrators, heirs, successors and assigns of the 
Optionee.

     5.   TERM OF OPTION.  This Option may be exercised only within the term 
set out in the Notice of Grant, and may be exercised during such term only in 
accordance with the Plan and the terms of this Option Agreement.

     6.   TAX CONSEQUENCES.  Some of the federal tax consequences relating to 
this Option, as of the date of this Option, are set forth below.  THIS 
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE 
SUBJECT TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE 
EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISING THE OPTION.

               (i)     NONSTATUTORY STOCK OPTION.  The Optionee may incur 
regular federal income tax liability upon exercise of a NSO.  The Optionee 
will be treated as having received compensation income (taxable at ordinary 
income tax rates) equal to the excess, if any, of the Fair Market Value of 
the Exercised Shares on the date of exercise over their aggregate Exercise 
Price.  If the Optionee is an Employee or a former Employee, the Company will 
be required to withhold from his or her compensation or collect from Optionee 
and pay to the applicable taxing authorities an amount in cash equal to a 
percentage of this compensation income at the time of exercise, and may 
refuse to honor the exercise and refuse to deliver Shares if such withholding 
amounts are not delivered at the time of exercise.

               (ii)     INCENTIVE STOCK OPTION.  If this Option qualifies as 
an ISO, the Optionee will have no regular federal income tax liability upon 
its exercise, although the excess, if any, of the Fair Market Value of the 
Exercised Shares on the date of exercise over their aggregate Exercise Price 
will be treated as an adjustment to alternative minimum taxable income for 
federal tax purposes and may subject the Optionee to alternative minimum tax 
in the year of exercise.  In the event that the Optionee ceases to be an 
Employee but remains a Service Provider, any Incentive Stock Option of the 
Optionee that remains unexercised shall cease to qualify as an Incentive 
Stock Option and will be treated for tax 

                                    B-3
<PAGE>

purposes as a Nonstatutory Stock Option on the date three (3) months and one 
(1) day following such change of status.

          (b)  DISPOSITION OF SHARES.  

               (i)     NSO.  If the Optionee holds NSO Shares for at least 
one year, any gain realized on disposition of the Shares will be treated as 
long-term capital gain for federal income tax purposes.

               (ii)    ISO.  If the Optionee holds ISO Shares for at least 
one year after exercise and two years after the grant date, any gain realized 
on disposition of the Shares will be treated as long-term capital gain for 
federal income tax purposes.  If the Optionee disposes of ISO Shares within 
one year after exercise or two years after the grant date, any gain realized 
on such disposition will be treated as compensation income (taxable at 
ordinary income rates) to the extent of the excess, if any, of the lesser of 
(A) the difference between the Fair Market Value of the Shares acquired on 
the date of exercise and the aggregate Exercise Price, or (B) the difference 
between the sale price of such Shares and the aggregate Exercise Price.  Any 
additional gain will be taxed as capital gain, short-term or long-term 
depending on the period that the ISO Shares were held.

          (c)  NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the 
Optionee sells or otherwise disposes of any of the Shares acquired pursuant 
to an ISO on or before the later of (i) two years after the grant date, or 
(ii) one year after the exercise date, the Optionee shall immediately notify 
the Company in writing of such disposition. The Optionee agrees that he or 
she may be subject to income tax withholding by the Company on the 
compensation income recognized from such early disposition of ISO Shares by 
payment in cash or out of the current earnings paid to the Optionee.

     7.   ENTIRE AGREEMENT; GOVERNING LAW.  The Plan is incorporated herein 
by reference.  The Plan and this Option Agreement constitute the entire 
agreement of the parties with respect to the subject matter hereof and 
supersede in their entirety all prior undertakings and agreements of the 
Company and Optionee with respect to the subject matter hereof, and may not 
be modified adversely to the Optionee's interest except by means of a writing 
signed by the Company and Optionee.  This agreement is governed by the 
internal substantive laws, but not the choice of law rules, of California.

     8.   NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES
AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE
HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL
OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED
AN OPTION OR PURCHASING SHARES HEREUNDER).  OPTIONEE FURTHER
ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT
AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT
ALL, AND SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S
RIGHT TO TERMINATE

                         SECURITY AGREEMENT



     This Security Agreement is made as of __________, 19___ between 
Cyberonics, Inc., a Delaware corporation ("Pledgee"), and 
_________________________ ("Pledgor").

                              RECITALS

     Pursuant to Pledgor's election to purchase Shares under the Option 
Agreement dated ________ (the "Option"), between Pledgor and Pledgee under 
Pledgee's 1997 Stock Plan, and Pledgor's election under the terms of the 
Option to pay for such shares with his promissory note (the "Note"), Pledgor 
has purchased _________ shares of Pledgee's Common Stock (the "Shares") at a 
price of $________ per share, for a total purchase price of $__________.  The 
Note and the obligations thereunder are as set forth in Exhibit C to the 
Option.

     NOW, THEREFORE, it is agreed as follows:

     1.   CREATION AND DESCRIPTION OF SECURITY INTEREST.  In consideration of 
the transfer of the Shares to Pledgor under the Option Agreement, Pledgor, 
pursuant to the California Commercial Code, hereby pledges all of such Shares 
(herein sometimes referred to as the "Collateral") represented by certificate 
number ______, duly endorsed in blank or with executed stock powers, and 
herewith delivers said certificate to the Secretary of Pledgee 
("Pledgeholder"), who shall hold said certificate subject to the terms and 
conditions of this Security Agreement.

The pledged stock (together with an executed blank stock assignment for use 
in transferring all or a portion of the Shares to Pledgee if, as and when 
required pursuant to this Security Agreement) shall be held by the 
Pledgeholder as security for the repayment of the Note, and any extensions or 
renewals thereof, to be executed by Pledgor pursuant to the terms of the 
Option, and the Pledgeholder shall not encumber or dispose of such Shares 
except in accordance with the provisions of this Security Agreement.

     2.   PLEDGOR'S REPRESENTATIONS AND COVENANTS.  To induce Pledgee to 
enter into this Security Agreement, Pledgor represents and covenants to 
Pledgee, its successors and assigns, as follows:

          a.   PAYMENT OF INDEBTEDNESS.  Pledgor will pay the principal sum 
of the Note secured hereby, together with interest thereon, at the time and 
in the manner provided in the Note.

          b.   ENCUMBRANCES.  The Shares are free of all other encumbrances, 
defenses and liens, and Pledgor will not further encumber the Shares without 
the prior written consent of Pledgee.



<PAGE>

          c.   MARGIN REGULATIONS.  In the event that Pledgee's Common Stock 
is now or later becomes margin-listed by the Federal Reserve Board and 
Pledgee is classified as a "lender" within the meaning of the regulations 
under Part 207 of Title 12 of the Code of Federal Regulations ("Regulation 
G"), Pledgor agrees to cooperate with Pledgee in making any amendments to the 
Note or providing any additional collateral as may be necessary to comply 
with such regulations.

     3.   VOTING RIGHTS.  During the term of this pledge and so long as all 
payments of principal and interest are made as they become due under the 
terms of the Note, Pledgor shall have the right to vote all of the Shares 
pledged hereunder.

     4.   STOCK ADJUSTMENTS.  In the event that during the term of the pledge 
any stock dividend, reclassification, readjustment or other changes are 
declared or made in the capital structure of Pledgee, all new, substituted 
and additional shares or other securities issued by reason of any such change 
shall be delivered to and held by the Pledgee under the terms of this 
Security Agreement in the same manner as the Shares originally pledged 
hereunder.  In the event of substitution of such securities, Pledgor, Pledgee 
and Pledgeholder shall cooperate and execute such documents as are reasonable 
so as to provide for the substitution of such Collateral and, upon such 
substitution, references to "Shares" in this Security Agreement shall include 
the substituted shares of capital stock of Pledgor as a result thereof.

     5.   OPTIONS AND RIGHTS.  In the event that, during the term of this 
pledge, subscription Options or other rights or options shall be issued in 
connection with the pledged Shares, such rights, Options and options shall be 
the property of Pledgor and, if exercised by Pledgor, all new stock or other 
securities so acquired by Pledgor as it relates to the pledged Shares then 
held by Pledgeholder shall be immediately delivered to Pledgeholder, to be 
held under the terms of this Security Agreement in the same manner as the 
Shares pledged.

     6.   DEFAULT.  Pledgor shall be deemed to be in default of the Note and 
of this Security Agreement in the event:

          a.   Payment of principal or interest on the Note shall be 
delinquent for a period of 10 days or more; or

          b.   Pledgor fails to perform any of the covenants set forth in the 
Option or contained in this Security Agreement for a period of 10 days after 
written notice thereof from Pledgee.

     In the case of an event of Default, as set forth above, Pledgee shall 
have the right to accelerate payment of the Note upon notice to Pledgor, and 
Pledgee shall thereafter be entitled to pursue its remedies under the 
California Commercial Code.

     7.   RELEASE OF COLLATERAL.  Subject to any applicable contrary rules 
under Regulation G, there shall be released from this pledge a portion of the 
pledged Shares held by Pledgeholder hereunder upon payments of the principal 
of the Note.  The number of the pledged Shares which shall be released shall 
be that number of full Shares which bears the same proportion to the initial 
number of Shares pledged hereunder as the payment of principal bears to the 
initial full principal amount of the Note.


                                      -2-

<PAGE>

     8.   WITHDRAWAL OR SUBSTITUTION OF COLLATERAL.  Pledgor shall not sell, 
withdraw, pledge, substitute or otherwise dispose of all or any part of the 
Collateral without the prior written consent of Pledgee.

     9.   TERM.  The within pledge of Shares shall continue until the payment 
of all indebtedness secured hereby, at which time the remaining pledged stock 
shall be promptly delivered to Pledgor, subject to the provisions for prior 
release of a portion of the Collateral as provided in paragraph 7 above.

     10.  INSOLVENCY.  Pledgor agrees that if a bankruptcy or insolvency 
proceeding is instituted by or against it, or if a receiver is appointed for 
the property of Pledgor, or if Pledgor makes an assignment for the benefit of 
creditors, the entire amount unpaid on the Note shall become immediately due 
and payable, and Pledgee may proceed as provided in the case of default.

     11.  PLEDGEHOLDER LIABILITY.  In the absence of willful or gross 
negligence, Pledgeholder shall not be liable to any party for any of his 
acts, or omissions to act, as Pledgeholder.

     12.  INVALIDITY OF PARTICULAR PROVISIONS.  Pledgor and Pledgee agree 
that the enforceability or invalidity of any provision or provisions of this 
Security Agreement shall not render any other provision or provisions herein 
contained unenforceable or invalid.

     13.  SUCCESSORS OR ASSIGNS.  Pledgor and Pledgee agree that all of the 
terms of this Security Agreement shall be binding on their respective 
successors and assigns, and that the term "Pledgor" and the term "Pledgee" as 
used herein shall be deemed to include, for all purposes, the respective 
designees, successors, assigns, heirs, executors and administrators.

     14.  GOVERNING LAW.  This Security Agreement shall be interpreted and 
governed under the internal substantive laws, but not the choice of law 
rules, of Texas.
