                              PROXY STATEMENT FOR
                      1997 ANNUAL MEETING OF STOCKHOLDERS
                                 JULY 15, 1997
 
                            ------------------------
 
              INFORMATION CONCERNING VOTING AND PROXY SOLICITATION
 
GENERAL
 
    The enclosed proxy is solicited on behalf of the Board of Directors of
Perclose, Inc. ("Perclose" or the "Company") for use at the Annual Meeting of
Stockholders to be held on July 15, 1997 at 10:00 a.m., local time, or at any
adjournment thereof. The Annual Meeting will be held at the Company's principal
executive offices, 199 Jefferson Drive, Menlo Park, California 94025. The
telephone number at the meeting location is (415) 473-3100.
 
    These proxy solicitation materials and the Annual Report to stockholders for
the fiscal year ended March 31, 1997 (the "Last Fiscal Year"), including
financial statements, were first mailed on or about June 13, 1997, to all
stockholders entitled to vote at the Annual Meeting.
 
RECORD DATE AND VOTING SECURITIES
 
    Stockholders of record at the close of business on May 30, 1997 (the "Record
Date") are entitled to notice of and to vote at the Annual Meeting. At the
Record Date, 9,579,747 shares of the Company's Common Stock, $0.001 par value
(the "Common Stock"), were issued and outstanding and held of record by
approximately 289 stockholders.
 
REVOCABILITY OF PROXIES
 
    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 meeting and voting in person. Attending the Annual
Meeting in and of itself may not constitute a revocation of a proxy.
 
VOTING AND SOLICITATION
 
    Each stockholder is entitled to one vote for each share held as of the
record date. Stockholders will not be entitled to cumulate their votes in the
election of directors.
 
    The cost of soliciting proxies will be borne by the Company. The Company
expects to reimburse brokerage firms and other persons representing beneficial
owners of shares for their expense in forwarding solicitation material to such
beneficial owners. Proxies may be solicited by certain of the Company's
directors, officers and regular employees, without additional compensation, in
person or by telephone or facsimile.
 
QUORUM; ABSTENTIONS; BROKER NON-VOTES
 
    Votes cast by proxy or in person at the Annual Meeting will be tabulated by
the Inspector of Elections (the "Inspector") with the assistance of the
Company's Transfer Agent. The Inspector will also determine whether or not a
quorum is present. Except in certain specific circumstances, the affirmative
vote of a majority of shares present in person or represented by proxy at a duly
held meeting at which a quorum is present is required under Delaware law for
approval of proposals presented to stockholders. In general, Delaware law also
provides that a quorum consists of a majority of shares entitled to vote and
present or represented by proxy at the meeting.
<PAGE>
    The Inspector will treat shares that are voted "WITHHELD" or "ABSTAIN" as
being present and entitled to vote for purposes of determining the presence of a
quorum but will not be treated as votes in favor of approving any matter
submitted to the stockholders for a vote. Any proxy which is returned using the
form of proxy enclosed and which is not marked as to a particular item will be
voted for the election of the two Class II directors, for the approval of the
adoption of the 1997 Stock Plan, for the approval of the amendment of the 1995
Director Option Plan, for the ratification of the appointment of the designated
independent auditors and, as the proxy holders deem advisable, on other matters
that may come before the meeting, as the case may be with respect to the items
not marked.
 
    If a broker indicates on the enclosed proxy or its substitute that it does
not have discretionary authority as to certain shares to vote on a particular
matter ("Broker Non-Votes"), those shares will not be considered as present with
respect to that matter. The Company believes that the tabulation procedures to
be followed by the Inspector are consistent with the general statutory
requirements in Delaware concerning voting of shares and determination of a
quorum.
 
DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS TO BE PRESENTED AT 1998 ANNUAL
  MEETING
 
    Proposals that are intended to be presented by stockholders of the Company
at the 1998 Annual Meeting must be received by the Company no later than
February 6, 1998 in order to be considered for inclusion in the proxy statement
and form of proxy relating to that meeting.
 
SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") requires the Company's executive officers and directors and
persons who own more than ten percent of a registered class of the Company's
equity securities to file an initial report of ownership on Form 3 and changes
in ownership on Form 4 or 5 with the Securities and Exchange Commission (the
"SEC") and the National Associates of Securities Dealers, Inc. Executive
officers, directors and greater than 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, or
written representations from certain reporting persons, the Company believes
that, with respect to fiscal year 1997, all filing requirements applicable to
its officers, directors and ten percent stockholders were complied with.

                                 PROPOSAL NO. 2
                          ADOPTION OF 1997 STOCK PLAN
 
    As of the date of this Proxy Statement, there remain available for grant
under the Company's 1992 Stock Plan (the "1992 Plan") options to purchase
172,336 shares of the Company's Common Stock. The 1992 Plan will remain in full
force and effect until it expires on its own terms and the Company will continue
to grant options pursuant to such plan until there are no longer shares
available for grant thereunder. In April 1997, the Board of Directors approved,
and recommended that the Company's stockholders approve, a new 1997 Stock Plan
(the "1997 Plan"), and reserved 500,000 shares of the Company's Common Stock for
issuance under the 1997 Plan. In addition, an annual increase will be made to
the 1997 Plan on each anniversary date of the adoption of the 1997 Plan, in an
amount equal to the lesser of (i) 5% of the Company's outstanding shares on such
date, or (ii) a lesser amount determined by the Board of Directors; provided,
however, that at no time shall the total number of shares reserved for issuance
under the 1997 Plan exceed 15% of the Company's outstanding shares; provided,
further, that over the ten year term of the 1997 Plan, a maximum of 15,000,000
shares may be issued under the 1997 Plan. As of the date of this Proxy
Statement, no options or stock have been granted pursuant to the 1997 Plan.
 
    In 1993, Section 162(m) was added to the Internal Revenue Code of 1986, as
amended. Section 162(m) may limit the Company's ability to deduct for federal
income tax purposes compensation in excess of $1,000,000 paid to the Company's
Chief Executive Officer and its four other highest paid executive officers in
any one fiscal year. Grants under the 1997 Plan will not be subject to the
deduction limitation if the stockholders approve the 1997 Plan, including the
option grant limitations described below.
 
    A description of the principal terms of the 1997 Plan and its purpose are
set forth below. This description is qualified in its entirety by the terms of
the 1997 Plan, which is attached to this Proxy Statement as EXHIBIT A and is
incorporated in this Proxy Statement by this reference.
 
SUMMARY OF THE 1997 PLAN
 
    GENERAL.  The purpose of the 1997 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
 
                                       7
<PAGE>
and consultants of the Company and to promote the success of the Company's
business. Options granted under the 1997 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. In addition, awards of or
rights to purchase shares of the Company's Common Stock ("Stock Rights") may be
granted under the 1997 Plan.
 
    ADMINISTRATION.  The 1997 Plan may generally be administered by the
Compensation Committee of the Board (the "Administrator"). Subject to the other
provisions of the 1997 Plan, the Board has the authority to (i) interpret the
1997 Plan and apply its provisions; (ii) prescribe, amend or rescind rules and
regulations relating to the 1997 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 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
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.
 
    ELIGIBILITY; LIMITATIONS.  Nonstatutory stock options and Stock Rights may
be granted under the 1997 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.
 
    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 Plan provides that no employee may be granted, in any fiscal year of
the Company, options to purchase more than 500,000 shares of Common Stock.
 
    TERMS AND CONDITIONS OF OPTIONS.  Each option granted under the 1997 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 price 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 price
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 nonstatutory stock option may be
determined by the Administrator, provided however, the exercise price of a
nonstatutory 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 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.
 
                                       8
<PAGE>
    (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 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 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 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 Plan
generally are not transferable other than by will or the laws of descent and
distribution, and 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 nonstatutory stock option.
 
    (i)  OTHER PROVISIONS.  The stock option agreement may contain other terms,
provisions and conditions not inconsistent with the 1997 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 Plan, the number and class of shares of stock subject to any
option or Stock Right outstanding under the 1997 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
 
                                       9
<PAGE>
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.
 
    AMENDMENT AND TERMINATION OF THE 1997 PLAN.  The Board may amend, alter,
suspend or terminate the 1997 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 Plan without the written
consent of the optionee/recipient. Unless terminated earlier, the 1997 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.
 
    NONSTATUTORY STOCK OPTIONS.  An optionee does not recognize any taxable
income at the time he or she is granted a nonstatutory 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
 
                                       10
<PAGE>
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 Plan. It does not
purport to be complete, and does not discuss the tax consequences of the
employee's, director's or consultant's death or the provisions of the income tax
laws of any municipality, state or foreign country in which the employee,
director or consultant may reside.
 
VOTE REQUIRED
 
    The approval of the adoption of the 1997 Plan requires the affirmative vote
of a majority of the shares of the Company's Common Stock present and voting at
the Annual Meeting.
 
    THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING "FOR" THE
ADOPTION OF THE 1997 STOCK PLAN.
 
                                 PROPOSAL NO. 3
           APPROVAL OF THE AMENDMENT OF THE 1995 DIRECTOR OPTION PLAN
 
SUMMARY OF THE 1995 DIRECTOR OPTION PLAN
 
    GENERAL.  The Company's 1995 Director Option Plan (the "Director Plan") was
adopted by the Board of Directors in September 1995 and approved by the
stockholders in October 1995. A total of 200,000 shares of Common Stock is
reserved for issuance under the Director Plan. As of May 30, 1997, options to
purchase up to 185,000 shares have been granted and remain outstanding and
15,000 shares remain available for future issuance under the Director Plan. In
April 1997, the Board of Directors authorized an amendment to the Director Plan,
subject to stockholder approval, to increase the number of shares reserved for
issuance thereunder by 200,000 shares, bringing the total number of shares
issuable under the Director Plan to 400,000 shares. The purposes of the Director
Plan are to attract and retain the best available personnel for service as
non-employee directors of the Company, to provide additional incentive to such
non-employee directors and to encourage their continued service on the Board.
 
    ADMINISTRATION.  The Director Plan is designed to be effective automatically
without requiring administration. However, to the extent administration is
necessary, it will be provided by the Board. The interpretation and construction
of any provision of the Director Plan by the Board shall be final and
conclusive. Members of the Board receive no additional compensation for their
services in connection with the administration of the Director Plan.
 
    TERMS OF OPTIONS.  The Director Plan provides for the grant of nonstatutory
stock options to non-employee directors of the Company. Each non-employee
director will be automatically granted an option (the "First Option") to
purchase 15,000 shares of Common Stock on the date on which the person first
becomes a non-employee director. Thereafter, each outside director shall be
automatically granted an option to purchase 5,000 shares of Common Stock (a
"Subsequent Option") on the first business day of each year provided he or she
is then an outside director and has served on the Board for at least six (6)
months. Options granted under the Director Plan expire ten (10) years after the
date of grant. Each
 
                                       11
<PAGE>
option is evidenced by a stock option agreement between the Company and the
director. The terms of the options under the Director Plan described above may
not be amended more than once every six (6) months, except for amendments to
comply with changes in applicable law.
 
    RULE 16B-3.  The Director Plan requires that options granted thereunder
comply with the applicable provisions of Rule 16b-3 promulgated under the
Exchange Act, or any successor thereto. Such options shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
the Director Plan transactions.
 
    EXERCISE OF THE OPTIONS.  The First Option shall become exercisable as to
one forty-eighth (1/48) of the shares subject thereto at the end of each full
month after its date of grant, so long as the Optionee continues to serve as a
director. Each Subsequent Option shall become exercisable as to one forty-eighth
(1/48) of the shares subject thereto at the end of each month after its date of
grant, so long as the Optionee continues to serve as a director on such dates.
The consideration to be paid for the shares to be issued upon exercise of an
Option, including the method of payment, shall consist of (i) cash, (ii) check,
(iii) other shares of Common Stock (with some restrictions), (iv) cashless
exercise, or (v) any combination of the foregoing methods of payment.
 
    OPTION PRICE.  The exercise price for all options granted under the Director
Plan is the fair market value of the Company's Common Stock on the date of
grant. The fair market value of a share of Common Stock is generally determined
with reference to the last reported sale price for such stock on the date of
grant.
 
    TERMINATION OF STATUS AS A DIRECTOR.  The Director Plan provides that if the
optionee ceases to serve as a director of the Company, the optionee may, but
only within 3 months after the date he or she ceases to be a director, exercise
his or her option to the extent that the optionee was entitled to exercise it at
the date of such termination, provided that the option is exercised no later
than its expiration date.
 
    DISABILITY.  If an optionee is unable to continue service as a director of
the Company as a result of his or her total and permanent disability, the
optionee may, but only within 12 months after the date of the optionee's
termination, exercise his or her option to the extent entitled to exercise it at
the date of such termination, provided that the option is exercised no later
than its expiration date.
 
    DEATH.  In the event of the death of an optionee, the option may be
exercised at any time within 12 months after death to the extent that the
optionee was entitled to exercise it on the date of death, provided that the
option is exercised no later than its expiration date.
 
    NONTRANSFERABILITY OF OPTIONS.  Options granted under the Director Plan are
nontransferable by the optionee, other than by will or the laws of descent and
distribution, and are exercisable during the optionee's lifetime only by the
optionee.
 
    ADJUSTMENTS; DISSOLUTIONS; MERGERS AND ASSET SALES.  In the event any change
is made in the Company's capitalization which results in an increase or decrease
in the number of issued shares of Common Stock without receipt of consideration
by the Company, an appropriate adjustment shall be made in the number of shares
under the Director Plan and the price per share covered by each outstanding
option. In the event of the proposed dissolution or liquidation of the Company,
all outstanding options will terminate immediately prior to the consummation of
such proposed action. In the event of a merger of the Company with or into
another corporation or the sale of all or substantially all of the assets of the
Company, each outstanding option shall be assumed or an equivalent option shall
be substituted by the successor corporation. In the event that the successor
corporation does not agree to assume the option or to substitute an equivalent
option, each outstanding option shall become fully vested and exercisable,
including as to shares as to which it would not otherwise be exercisable.
 
                                       12
<PAGE>
    AMENDMENT AND TERMINATION.  The Board may amend, alter, suspend or
discontinue the Director Plan at any time, but any such action shall not
adversely affect any stock option then outstanding under the Director Plan
without the consent of the holder thereof. To the extent necessary and desirable
to comply with Rule 16b-3 (or any other applicable law or regulation), the
Company shall obtain stockholder approval of any amendment to the Director Plan
in such a manner and to such a degree as required. The Director Plan shall
terminate in September 2005. Any options outstanding under the Director Plan at
the time of its termination shall remain outstanding until they expire by their
terms.
 
CERTAIN FEDERAL INCOME TAX INFORMATION
 
    Options granted under the Director Plan are nonstatutory stock options. An
optionee will not recognize any taxable income at the time of grant of an
option. Upon its exercise, the optionee may recognize ordinary income measured
by the excess of the then fair market value of the shares over the exercise
price. However, because the optionee is a director of the Company and subject to
Section 16 of the Exchange Act, the date of taxation (and the date of
measurement of ordinary income) may be deferred unless the optionee files an
election under Section 83(b) of the Code. Upon resale of such shares by the
optionee, any difference between the sale price and the exercise price, to the
extent not recognized as ordinary income as provided above, will be treated as
capital gain or loss. The Company will be entitled to a tax deduction in the
amount and at the time that the optionee recognizes ordinary income with respect
to shares acquired upon exercise of an option.

                      BOARD COMPENSATION COMMITTEE REPORT
                           ON EXECUTIVE COMPENSATION
 
    THE FOLLOWING IS PROVIDED TO STOCKHOLDERS BY THE MEMBERS OF THE COMPENSATION
COMMITTEE OF THE BOARD OF DIRECTORS:
 
    The Compensation Committee of the Board of Directors (the "Committee"),
comprising three outside directors, is responsible for the administration of the
Company's compensation programs. These programs include base salary for
executive officers and both annual and long-term incentive compensation
programs. The Company's compensation programs are designed to provide a
competitive level of total compensation and include incentive and equity
ownership opportunities linked to the Company's performance and stockholder
return.
 
COMPENSATION PHILOSOPHY
 
    The design and implementation of the Company's executive compensation
programs are based on a series of guiding principles derived from the Company's
values, business strategy and management requirements. These principles may be
summarized as follows:
 
    - Align the financial interests of the management team with the Company and
      its stockholders;
 
    - Attract, motivate and retain high-caliber individuals necessary to
      increase total return to stockholders;
 
    - Provide a total compensation program where a significant portion of pay is
      linked to short- and long-term Company performance; and
 
    - Emphasize reward for performance at the individual, team and Company
      levels.
 
COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M)
 
    The Committee has considered the potential impact of Section 162(m) of the
Internal Revenue Code adopted under the Federal Revenue Reconciliation Act of
1993. Section 162(m) disallows a tax deduction for any publicly-held corporation
for individual compensation exceeding $1 million in any taxable year for any of
the named executive officers, unless compensation is performance based. Since
the targeted cash compensation of each of the named executive officers is well
below the $1 million threshold and the Committee believes that any options
granted under the Company's stock option plan will meet the requirement of being
performance based under the transition provisions provided in the regulations
under Section 162(m), the Committee believes that Section 162(m) will not reduce
the tax deduction available to the Company. The Company's policy is to qualify
to the extent reasonable its executive officers' compensation for deductibility
under applicable tax laws.
 
COMPENSATION PROGRAM
 
    The Company's executive compensation program has three major components, all
of which are intended to attract, retain and motivate executive officers
consistent with the principles set forth above. The Committee considers these
components of compensation individually as well as collectively in determining
total compensation for executive officers.
 
    1.  BASE SALARY. Each fiscal year the Committee establishes base salaries
for individual executive officers based upon (i) industry and peer group
surveys, (ii) responsibilities, scope and complexity of each position and (iii)
performance judgments as to each individual's past and expected future
contributions. The Committee reviews with the Chief Executive Officer and
approves, with appropriate modifications, an annual base salary plan for the
Company's executive officers other than the Chief Executive Officer. The
Committee reviews and fixes the base salary of the Chief Executive Officer based
on similar competitive
 
                                       17
<PAGE>
compensation data and the Committee's assessment of his past performance and its
expectations as to his future contributions in leading the Company.
 
    2.  ANNUAL CASH (SHORT-TERM) INCENTIVES. Annual cash incentives are
established to provide a direct linkage between individual pay and annual
corporate performance. Target annual bonus awards are established for executive
officer positions and other members of management. Different levels of
management have different target annual cash bonuses, but all members of a
management level have the same target annual cash bonus. The target annual cash
bonuses are based upon industry and peer group surveys and ranged from 12% to
16% of base salary, with 16% for the Chief Executive Officer, in fiscal 1997.
Each officer who served in an executive capacity during the Last Fiscal Year,
including the Chief Executive Officer, received a cash bonus for such service
ranging in amount from approximately 7% to approximately 9% of base salary.
Annual bonus payments are based on achieving a set of specific corporate goals
established at the beginning of the fiscal year. The goals are weighted
individually with the total for all goals equal to 100%. Annual cash bonus
payments for the management team are a result of the total percentage of goals
achieved multiplied by the management level's target annual cash bonus. In
establishing bonus payments for the Last Fiscal Year, the Committee measured
progress in the Company's product development programs and clinical trials
during the year, as well as financial performance for the Last Fiscal Year. Each
officer may receive a portion or the full amount of his target annual cash
bonus. The bonus award to the Chief Executive Officer in fiscal 1997 was
approximately 9% of his base salary.
 
    3.  EQUITY (LONG-TERM) BASED INCENTIVE COMPENSATION. Long-term incentives
for the Company's employees are provided under the Company's stock option plans.
Each fiscal year, the Committee considers the desirability of granting to
executive officers long-term incentives in the form of stock options. These
option grants are intended to motivate the executive officers to manage the
business to improve long-term Company performance and align the financial
interests of the management team with the Company and its stockholders. The
Committee established the grants of stock options to executive officers (other
than the Chief Executive Officer) in the Last Fiscal Year based upon a review
with the Chief Executive Officer of proposed individual awards, taking into
account each officer's scope of responsibility and specific assignments,
strategic and operational goals applicable to the officer, anticipated
performance requirements and contributions of the officer and competitive data
for similar positions. The Committee independently reviewed these same factors
in determining the option grant to the Chief Executive Officer. During the Last
Fiscal Year, option awards exercisable for up to an aggregate of 9,000 shares of
Common Stock were granted to the Chief Executive Officer. These were the only
option grants made to the Chief Executive Officer since January 31, 1996. All
stock options granted to executive officers in the Last Fiscal Year provide for
vesting over a four-year period.

    The following graph compares the cumulative total return to stockholders of
the Company's Common Stock at March 31, 1997 since November 7, 1995 (the date

Act) to the cumulative total return over such period of (i) the "Nasdaq Stock
Market -- U.S." index and (ii) the Hambrecht & Quist "Healthcare, Excluding
Biotechnology" index. The graph assumes the investment of $100 on November 7,
1995 in the Company's Common Stock and each of such indices (from October 31,
1995) and reflects the change in the market price of the Company's Common Stock
relative to the noted indices at March 31, 1997 and not for any interim period.
The performance shown is not necessarily indicative of future price performance.

    4.  ADMINISTRATION OF THE PLAN.
 
        (a) PROCEDURE.
 
            (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
       Purchase Rights may be granted hereunder;
 
           (iii) to determine the number of shares of Common Stock to be covered
       by each Option and Stock Purchase Right granted hereunder;
 
            (iv) to approve forms of agreement for use under the Plan;
<PAGE>
            (v) to determine the terms and conditions, not inconsistent with the
       terms of the Plan, of any Option or Stock Purchase Right granted
       hereunder. Such terms and conditions include, but are not limited to, the
       exercise price, the time or times when Options or Stock Purchase 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 Purchase 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 Purchase
       Right to the then current Fair Market Value if the Fair Market Value of
       the Common Stock covered by such Option or Stock Purchase Right shall
       have declined since the date the Option or Stock Purchase 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 Purchase 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 Purchase 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 Purchase
       Right previously granted by the Administrator;
 
          (xiii) to make all other determinations deemed necessary or advisable
       for administering the Plan.
 
        (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 Purchase Rights.
 
    5.  ELIGIBILITY.  Nonstatutory Stock Options and Stock Purchase 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 Purchase Right shall confer
    upon an Optionee any right with respect to continuing the Optionee's
    relationship as a Service Provider with the Company,
<PAGE>
    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 500,000 Shares.
 
            (ii) In connection with his or her initial service, a Service
       Provider may be granted Options to purchase up to an additional 500,000
       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.
 
    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.
<PAGE>
        (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;
 
            (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 STOCKHOLDER. 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 stockholder 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.
 
        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
<PAGE>
    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.
 
    11.  STOCK PURCHASE RIGHTS.
 
        (a) RIGHTS TO PURCHASE. Stock Purchase 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 Purchase 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 that the offeree shall be entitled to
    purchase, the price to be paid, and the time within which the offeree must
    accept such offer. The offer shall be accepted by execution of a Restricted
    Stock Purchase Agreement in the form determined by the Administrator.
 
        (b) REPURCHASE OPTION. Unless the Administrator determines otherwise,
    the Restricted Stock Purchase Agreement shall grant the Company a repurchase
    option exercisable upon the voluntary or involuntary termination of the
    purchaser's service with the Company for any reason (including death or
    Disability). The purchase price for Shares repurchased pursuant to the
    Restricted Stock Purchase Agreement shall be the original price paid by the
    purchaser and may be paid by cancellation of any indebtedness of the
    purchaser to the Company. The repurchase option shall lapse at a rate
    determined by the Administrator.
 
        (c) OTHER PROVISIONS. The Restricted Stock Purchase 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.
<PAGE>
        (d) RIGHTS AS A STOCKHOLDER. Once the Stock Purchase Right is exercised,
    the purchaser shall have the rights equivalent to those of a stockholder,
    and shall be a stockholder when his or her purchase 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 the Stock Purchase Right is exercised, except as provided
    in Section 13 of the Plan.
 
    12.  NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS.  Unless
determined otherwise by the Administrator, an Option or Stock Purchase 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 Purchase Right transferable, such Option
or Stock Purchase 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
    stockholders of the Company, the number of shares of Common Stock covered by
    each outstanding Option and Stock Purchase 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 Purchase Rights have yet been granted or
    which have been returned to the Plan upon cancellation or expiration of an
    Option or Stock Purchase Right, as well as the price per share of Common
    Stock covered by each such outstanding Option or Stock Purchase Right, shall
    be proportionately adjusted for any increase or decrease in the number of
    issued shares of Common Stock resulting from a 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 Purchase
    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 ten (10) 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 repurchase option
    applicable to any Shares purchased upon exercise of an Option or Stock
    Purchase 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 Purchase Right will terminate immediately prior to the consummation
    of such proposed action.
 
        (c) MERGER OR ASSET SALE. 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 Purchase 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 Purchase Right, the Optionee shall fully vest in and have
    the right to exercise the Option or Stock Purchase Right as to all of the
    Optioned Stock, including Shares as to which it would not otherwise be
    vested or exercisable. If an Option or Stock Purchase 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 Purchase 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 Purchase Right shall terminate upon
    the expiration of such period. For the purposes of this paragraph, the
    Option or
<PAGE>
    Stock Purchase 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
    Purchase 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
    Purchase Right, for each Share of Optioned Stock subject to the Option or
    Stock Purchase Right, to be solely common stock of 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.
 
    14.  DATE OF GRANT.  The date of grant of an Option or Stock Purchase Right
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase 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) STOCKHOLDER APPROVAL. The Company shall obtain stockholder 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 Purchase Right unless the exercise of such
    Option or Stock Purchase 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 Purchase Right, the Company may require the person
    exercising such Option or Stock Purchase Right to represent and warrant at
    the time of any such exercise that the Shares are being purchased 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.  STOCKHOLDER APPROVAL.  The Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

    4.   ADMINISTRATION AND GRANTS OF OPTIONS UNDER THE PLAN.

         (a)  PROCEDURE FOR GRANTS.  The provisions set forth in this Section 
4(a) shall not be amended more than once every six months, other than to 
comport with changes in the Code, the Employee Retirement Income Security Act 
of 1974, as amended, or the rules thereunder.  All grants of Options to 
Outside Directors under this Plan shall be automatic and nondiscretionary and 
shall be made strictly in accordance with the following provisions:

                   (i)  No person shall have any discretion to select which 
Outside Directors shall be granted Options or to determine the number of 
Shares to be covered by Options granted to Outside Directors.

                  (ii)  Each New Outside Director shall be automatically
granted an Option to purchase fifteen thousand (15,000) Shares (a "First
Option") on the date on which such person first becomes a Director, whether
through election by the stockholders of the Company or appointment by the Board
to fill a vacancy.  Each Outside Director shall be automatically granted an
Option to purchase fifteen thousand (15,000) Shares (a "First Option") on the
effective date of the first public offering of the Company's Common Stock
pursuant to a registration statement under the Securities Act of 1933, as
amended.

                 (iii)  After a First Option has been granted to a New 
Outside Director or Outside Director, such individual shall thereafter be 
automatically granted an Option to purchase five thousand (5,000) Shares (a 
"Subsequent Option") on the first business day of each calendar year, if on 
such date, he shall have served on the Board for at least six (6) months.

                  (iv)  Notwithstanding the provisions of subsections (ii) 
and (iii) hereof, any exercise of an Option made before the Company has 
obtained stockholder approval of the Plan in accordance with Section 16 
hereof shall be conditioned upon obtaining such stockholder approval of the 
Plan in accordance with Section 16 hereof.

                   (v)  The terms of a First Option granted hereunder shall 
be as follows:

                        (A)  the term of the First Option shall be 
ten (10) years.

                        (B)  the First Option shall be exercisable only while 
the Outside Director remains a Director of the Company, except as set forth 
in Section 8 hereof.

                        (C)  the exercise price per Share shall be 100% of 
the fair market value per Share on the date of grant of the First Option.  In 
the event that the date of grant of the First Option is not a trading day, 
the exercise price per Share shall be the Fair Market Value on the next 
trading day immediately following the date of grant of the First Option.

                                        -3-

<PAGE>


                        (D)  the First Option shall become exercisable as to 
1/48 of the Shares subject to the First Option at the end of each full month 
following the date of grant,  subject to continued service as an Outside 
Director.

                   (vi) The terms of a Subsequent Option granted hereunder 
shall be as follows:

                        (A)  the term of the Subsequent Option shall be ten 
(10) years.

                        (B)  the Subsequent Option shall be exercisable only 
while the Outside Director remains a Director of the Company, except as set 
forth in Section 8 hereof.

                        (C)  the exercise price per Share shall be 100% of 
the fair market value per Share on the date of grant of the Subsequent 
Option.  In the event that the date of grant of the First Option is not a 
trading day, the exercise price per Share shall be the Fair Market Value on 
the next trading day immediately following the date of grant of the First 
Option.

                        (D)  the Subsequent Option shall become exercisable 
as to 1/48 of the Shares subject to the Subsequent Option at the end of each 
full month following the date of grant, subject to continued service as an 
Outside Director.

                   (vii)  In the event that any Option granted under the 
Plan would cause the number of Shares subject to outstanding Options plus the 
number of Shares previously purchased under Options to exceed the Pool, then 
the remaining Shares available for Option grant shall be granted under 
Options to the Outside Directors on a pro rata basis.  No further grants 
shall be made until such time, if any, as additional Shares become available 
for grant under the Plan through action of the stockholders to increase the 
number of Shares which may be issued under the Plan or through cancellation 
or expiration of Options previously granted hereunder.

    5.   ELIGIBILITY.  Options may be granted only to Outside Directors.  All
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.  An Outside Director who has been granted an Option may, if he
is otherwise eligible, be granted an additional Option or Options in accordance
with such provisions.

         The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate his or her directorship at any time.

    6.   TERM OF PLAN.  The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the stockholders of the
Company as described in Section 16 of the Plan.  It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 11 of the Plan.

                                        -4-

<PAGE>


    7.   FORM OF CONSIDERATION.  The consideration to be paid for the Shares to
be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) 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 (y) 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, (iv) delivery of a properly
executed exercise notice together with such other documentation as the Company
and the broker, if applicable, shall require to effect an exercise of the Option
and delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (v) any combination of the foregoing methods of payment.

    8.   EXERCISE OF OPTION.

         (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option 
granted hereunder shall be exercisable at such times as are set forth in 
Section 4 hereof; provided, however, that no Options shall be exercisable 
until stockholder approval of the Plan in accordance with Section 16 hereof 
has been obtained.

         An Option may not be exercised for a fraction of a Share.

         An Option shall be deemed to be exercised when written notice of 
such exercise has been given to the Company in accordance with the terms of 
the Option 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.  Full payment may consist of any consideration and method of 
payment allowable under Section 7 of the Plan.  Until the issuance (as 
evidenced by the appropriate entry on the books of the Company or of a duly 
authorized transfer agent of the Company) of the stock certificate evidencing 
such Shares, no right to vote or receive dividends or any other rights as a 
stockholder shall exist with respect to the Optioned Stock, notwithstanding 
the exercise of the Option. A share certificate for the number of Shares so 
acquired shall be issued to the Optionee as soon as practicable after 
exercise of the Option. No adjustment shall be made for a dividend or other 
right for which the record date is prior to the date the stock certificate is 
issued, except as provided in Section 10 of the Plan.

         Exercise of an Option in any manner shall result in a decrease in 
the number of Shares which thereafter may be available, both for purposes of 
the Plan and for sale under the Option, by the number of Shares as to which 
the Option is exercised.

         (b)  RULE 16B-3.  Options granted to Outside Directors must comply 
with the applicable provisions of Rule 16b-3 promulgated under the Exchange 
Act or any successor thereto and shall contain such additional conditions or 
restrictions as may be required thereunder to qualify Plan transactions, and 
other transactions by Outside Directors that otherwise could be matched with 
Plan transactions, for the maximum exemption from Section 16 of the Exchange 
Act.

         (c)  TERMINATION OF CONTINUOUS STATUS AS A DIRECTOR.  In the event an
Optionee's Continuous Status as a Director terminates (other than upon the
Optionee's death or disability), the Optionee may exercise his or her Option,
but only within three (3) months from the date of such termination, and only to
the extent that the Optionee was entitled to exercise it on the date of such
termination (but in no event later than the expiration of its ten (10) year
term).  To the extent that the Optionee was not entitled to exercise an Option
on the date of such termination, and to the extent that the Optionee does not
exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

         (d)  DISABILITY OF OPTIONEE.  In the event Optionee's Continuous 
Status as a Director terminates as a result of disability, the Optionee may 
exercise his or her Option, but only within twelve (12) months from the date 
of such termination, and only to the extent that the Optionee was entitled to 
exercise it on the date of such termination (but in no event later than the 
expiration of its ten (10) year term).  To the extent that the Optionee was 
not entitled to exercise an Option on the date of termination, or if he or 
she does not exercise such Option (to the extent otherwise so entitled) 
within the time specified herein, the Option shall terminate.

         (e)  DEATH OF OPTIONEE.  In the event of an Optionee's death, the 
Optionee's estate or a person who acquired the right to exercise the Option 
by bequest or inheritance may exercise the Option, but only within twelve 
(12) months following the date of death, and only to the extent that the 
Optionee was entitled to exercise it on the date of death (but in no event 
later than the expiration of its ten (10) year term).  To the extent that the 
Optionee was not entitled to exercise an Option on the date of death, and to 
the extent that the Optionee's estate or a person who acquired the right to 
exercise such Option does not exercise such Option (to the extent otherwise 
so entitled) within the time specified herein, the Option shall terminate.

    9.   NON-TRANSFERABILITY OF OPTIONS.  The Option 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.

    10.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER, 
         ASSET SALE OR CHANGE OF CONTROL. 

         (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by 
the stockholders of the Company, the number of Shares covered by each 
outstanding Option, 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 price per Share covered by each such outstanding 
Option, and the number of Shares issuable pursuant to the automatic grant 
provisions of Section 4 hereof shall be proportionately adjusted for any 
increase or decrease in the number of issued Shares resulting from a 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 effected without receipt of consideration by the Company; 

                                        -6-

<PAGE>

provided, however, that conversion of any convertible securities of the 
Company shall not be deemed to have been "effected without receipt of 
consideration."  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 subject 
to an Option.

         (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed 
dissolution or liquidation of the Company, to the extent that an Option has 
not been previously exercised, it will terminate immediately prior to the 
consummation of such proposed action.

         (c)  MERGER OR ASSET SALE.  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 shall be assumed or an 
equivalent option shall be substituted by the successor corporation or a 
Parent or Subsidiary of the successor corporation.  In the event that the 
successor corporation does not agree to assume the Option or to substitute an 
equivalent option, each outstanding Option shall become fully vested and 
exercisable, including as to Shares as to which it would not otherwise be 
exercisable.  If an Option becomes fully vested and exercisable in the event 
of a merger or sale of assets, the Board shall notify the Optionee that the 
Option shall be fully exercisable for a period of thirty (30) days from the 
date of such notice, and the Option shall terminate upon the expiration of 
such period.  For the purposes of this paragraph, the Option shall be 
considered assumed if, following the merger or sale of assets, the option or 
right confers the right to purchase, for each Share of Optioned Stock subject 
to the Option 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).

    11.  AMENDMENT AND TERMINATION OF THE PLAN.

         (a)  AMENDMENT AND TERMINATION.  Except as set forth in Section 4, 
the Board may at any time amend, alter, suspend, or discontinue the Plan, but 
no amendment, alteration, suspension, or discontinuation shall be made which 
would impair the rights of any Optionee under any grant theretofore made, 
without his or her consent.  In addition, to the extent necessary and 
desirable to comply with Rule 16b-3 under the Exchange Act (or any other 
applicable law or regulation), the Company shall obtain stockholder approval 
of any Plan amendment in such a manner and to such a degree as required.

         (b)  EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or 
termination of the Plan shall not affect Options already granted and such 
Options shall remain in full force and effect as if this Plan had not been 
amended or terminated.

                                        -7-

    12.  TIME OF GRANTING OPTIONS.  The date of grant of an Option shall, for 
all purposes, be the date determined in accordance with Section 4 hereof.  

    13.  CONDITIONS UPON ISSUANCE OF SHARES.  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 Exchange Act, the rules and regulations 
promulgated thereunder, state securities laws, and the requirements of any 
stock exchange upon which the Shares may then be listed, and shall be further 
subject to the approval of counsel for the Company with respect to such 
compliance.

         As a condition to the exercise of an Option, the Company may require 
the person exercising such Option to represent and warrant at the time of any 
such exercise that the Shares are being purchased 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 by any 
of the aforementioned relevant provisions of law.

         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.

    14.  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.

    15.  OPTION AGREEMENT.  Options shall be evidenced by written option 
agreements in such form as the Board shall approve.

    16.  STOCKHOLDER APPROVAL.  Continuance of the Plan shall be subject to
approval by the stockholders of the Company at or prior to the first annual
meeting of stockholders held subsequent to the granting of an Option hereunder. 
Such stockholder approval shall be obtained in the degree and manner required
under applicable state and federal law.
