                                CONDUCTUS, INC.
                     1992 STOCK OPTION/STOCK ISSUANCE PLAN
                  (AMENDED AND RESTATED EFFECTIVE MAY 25, 2000)

                                  ARTICLE ONE
                                    GENERAL

I.  PURPOSE OF THE PLAN

    A. This 1992 Stock Option/Stock Issuance Plan (the "Plan") is intended to
promote the interests of Conductus, Inc., a Delaware corporation (the
"Corporation"), by providing eligible individuals with the opportunity to
acquire a proprietary interest, or otherwise increase their proprietary
interest, in the Corporation as an incentive for them to remain in the service
of the Corporation (or its parent or subsidiary corporations).

    B.  The Plan serves as the successor to the Corporation's 1987 Stock Option
Plan and 1989 Stock Option Plan (collectively, the "Predecessor Plans"), and no
further option grants shall be made under the Predecessor Plans. All options
outstanding under the Predecessor Plans have been incorporated into this Plan
and shall accordingly be treated as outstanding options under this Plan.

    C.  For purposes of the Plan, the following provisions shall be applicable
in determining the parent and subsidiary corporations of the Corporation:

        Any corporation (other than the Corporation) in an unbroken chain of
    corporations ending with the Corporation shall be considered to be a PARENT
    of the Corporation, provided each such corporation in the unbroken chain
    (other than the Corporation) owns, at the time of the determination, stock
    possessing fifty percent (50%) or more of the total combined voting power of
    all classes of stock in one of the other corporations in such chain.

        Each corporation (other than the Corporation) in an unbroken chain of
    corporations beginning with the Corporation shall be considered to be a
    SUBSIDIARY of the Corporation, provided each such corporation (other than
    the last corporation) in the unbroken chain owns, at the time of the
    determination, stock possessing fifty percent (50%) or more of the total
    combined voting power of all classes of stock in one of the other
    corporations in such chain.

II.  STRUCTURE OF THE PLAN

    A. The Plan shall be divided into three separate components: the
Discretionary Option Grant Program specified in Article Two, the Automatic
Option Grant Program specified in Article Three, and the Stock Issuance Program
specified in Article Four. Under the Discretionary Option Grant Program,
eligible individuals may be granted options to purchase shares of the
Corporation's common stock (the "Common Stock"). Under the Automatic Option
Grant Program, members of the Corporation's Board of Directors (the "Board") who
are not employees of the Corporation or its subsidiaries (the "Outside
Directors") automatically receive non-statutory options to purchase shares of
Common Stock. The Stock Issuance Program shall allow eligible individuals to
purchase shares of Common Stock; such shares may be issued as fully-vested
shares or as shares vesting over time.

    B.  The provisions of Articles One and Five of the Plan shall apply to the
Discretionary Option Grant Program, the Automatic Option Grant Program, and the
Stock Issuance Program unless otherwise indicated.

III.  ADMINISTRATION OF THE PLAN

    A. The Plan shall be administered by a committee (the "Committee") of two
(2) or more Outside Directors appointed by the Board. Members of the Committee
shall serve for such period of time as the Board may determine and shall be
subject to removal by the Board at any time.

    B.  The Committee, acting as plan administrator (the "Plan Administrator"),
shall have full power and authority (subject to the express provisions of the
Plan) to establish such rules and regulations as it may deem appropriate for the
proper administration of the Plan and to make such determinations under, and
issue such interpretations of, the Plan and any outstanding option grants or
stock issuances as it may deem necessary or advisable. Decisions of the Plan
Administrator shall be final and binding on all parties who have an interest in
the Plan or any outstanding option or stock issuance.

    C.  Service on the Committee shall constitute service as a Board member, and
members of the Committee shall accordingly be entitled to full indemnification
and reimbursement as Board members for their service on the Committee. No member
of the Committee shall be liable for any act or omission made in good faith with
respect to the Plan or any option granted under the Plan.

IV.  OPTION GRANTS AND STOCK ISSUANCES

    A. The persons eligible to receive stock issuances under the Stock Issuance
Program (the "Participants") and/or option grants under the Discretionary Option
Grant Program (the "Optionees") are as follows:

<PAGE>

        (1) key employees (including officers and directors) of the Corporation
    (or its parent or subsidiary corporations) who render services which
    contribute to the management, growth and financial success of the
    Corporation (or its parent or subsidiary corporations),

        (2) members of the Board, and

        (3) those consultants or other independent contractors who provide
    valuable services to the Corporation (or its parent or subsidiary
    corporations).

    B.  Outside Directors shall receive options in accordance with the Plan's
Automatic Option Grant Program; provided, however, that nothing in the Plan
shall be construed to prevent an Outside Director from declining to receive an
option under this Plan.

    C.  The Plan Administrator shall have full authority to determine (i) with
respect to the discretionary option grants made under Article Two, which
eligible individuals are to receive option grants, the number of shares to be
covered by each such grant, whether the granted option is to be an incentive
stock option ("Incentive Option") which satisfies the requirements of
Section 422 of the Internal Revenue Code or a non-statutory option not intended
to meet such requirements, the time or times at which each granted option is to
become exercisable and the maximum term for which the option may remain
outstanding and (ii) with respect to stock issuances under the Stock Issuance
Program, which eligible individuals are to be selected for participation, the
number of shares to be issued to each Participant, the vesting schedule (if any)
to be applicable to the issued shares, and the consideration to be paid by the
Participant for such shares.

    D. The Plan Administrator shall have the absolute discretion either to grant
options in accordance with Article Two of the Plan or to effect stock issuances
in accordance with Article Four of the Plan.

V.  STOCK SUBJECT TO THE PLAN

    A. SHARES AVAILABLE

    (1) Shares of Common Stock shall be available for issuance under the Plan
and shall be drawn from either the Corporation's authorized but unissued shares
of Common Stock or from reacquired shares of Common Stock, including shares
repurchased by the Corporation on the open market. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
4,580,000(2) shares of Common Stock, subject to adjustment from time to time in
accordance with the provisions of this Section V. To the extent one or more

------------------------
(2) Reflects the 300,000-share increase authorized by the Board in January
    1996 and approved by the stockholders at the 1996 Annual Stockholders'
    Meeting; the 200,000-share increase authorized by the Board in October 1996
    and approved by the stockholders at the 1997 Annual Stockholders' Meeting;
    the 500,000 share increase authorized by the Board in April 1999 and
    approved by the stockholders at the 1999 Annual Stockholders' Meeting and
    the 2,000,000-share increase authorized by the Board in April 2000, and
    approved by the stockholders at the 2000 Annual Stockholders' Meeting.

<PAGE>

outstanding options under the Predecessor Plans which have been incorporated
into this Plan are subsequently exercised, the number of shares issued with
respect to each such option shall reduce, on a share-for-share basis, the number
of shares available for issuance under this Plan.

    (2) Effective on the first day of each fiscal year of the Company, beginning
on January 1, 2001, the number of shares of Stock available shall automatically
be increased by an amount, rounded to the nearest whole share (the "Annual
Increase Shares"), equal to four percent (4%) of the aggregate number of shares
of Stock outstanding as of such date ("Outstanding Shares") or such lessor
number of shares as determined by the Board; provided that, with respect to each
such increase effective on the first day of each fiscal year of the Company
beginning on January 1, 2001, the number of Annual Increase Shares shall be
reduced by the number of shares of Stock subject to the Plan that are not
then-issued and are not subject to the then-outstanding option grants as of such
effective date (the "Available Shares"), provided that, no reduction shall be
made if the Available Shares equal to one percent (1%) or less of the aggregate
number of Outstanding Shares as of such effective date.

    B.  In no event may any one individual participating in the Plan be granted
stock options and direct stock issuances for more than 750,000 shares of Common
Stock per calendar year, subject to adjustment from time to time in accordance
with the provisions of this Section V.

    C.  Should one or more outstanding options under this Plan (including
outstanding options under the Predecessor Plans incorporated into this Plan)
expire or terminate for any reason prior to exercise in full (including any
option cancelled in accordance with the cancellation-regrant provisions of
Section IV of Article Two of the Plan), then the shares subject to the portion
of each option not so exercised shall be available for subsequent option grant
or share issuance under the Plan. Shares subject to any option or portion
thereof cancelled in accordance with Section V of Article Two and shares
repurchased by the Corporation pursuant to its repurchase rights under the Plan
or otherwise surrendered for cancellation under Section I(B)(3) of Article Four
shall NOT be available for subsequent option grant or stock issuance under the
Plan. In addition, should the exercise price of an outstanding option under the
Plan (including any option incorporated from the Predecessor Plans) be paid with
shares of Common Stock, then the number of shares of Common Stock available for
issuance under the Plan shall be reduced by the gross number of shares for which
the option is exercised, and not by the net number of shares of Common Stock
actually issued to the option holder.

    D. In the event any change is made to the Common Stock issuable under the
Plan by reason of any stock split, stock dividend, recapitalization, combination
of shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without receipt of consideration, then appropriate adjustments
shall be made to (i) the maximum number and/or class of shares issuable under
the Plan, (ii) the maximum number and/or class of shares for which any one
individual participating in the Plan may be granted stock options and direct
stock issuances per calendar year, (iii) the number and/or class of shares for
which an Outside Director is granted

<PAGE>

stock options in accordance with the Plan's Automatic Option Grant Program,
(iv) the number and/or class of shares and price per share in effect under
each outstanding option under the Plan and (v) the number and/or class of
shares and price per share in effect under each outstanding option
incorporated into this Plan from the Predecessor Plans. Such adjustments to
the outstanding options are to be effected in a manner which shall preclude
the enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

    E.  Common Stock issuable under the Plan, whether under the Discretionary
Option Grant Program or the Stock Issuance Program, may be subject to such
restrictions on transfer, repurchase rights or other restrictions as may be
determined by the Plan Administrator.

                                  ARTICLE TWO
                       DISCRETIONARY OPTION GRANT PROGRAM

I.  TERMS AND CONDITIONS OF OPTIONS

    Discretionary options granted pursuant to the Plan shall be authorized by
action of the Plan Administrator and may, at the Plan Administrator's
discretion, be either Incentive Options or non-statutory options. Individuals
who are not Employees may only be granted non-statutory options. Each granted
option shall be evidenced by one or more instruments in the form approved by the
Plan Administrator; PROVIDED, however, that each such instrument shall comply
with the terms and conditions specified below. Each instrument evidencing an
Incentive Option shall, in addition, be subject to the applicable provisions of
Section II of this Article Two.

    A.  OPTION PRICE.

    (1) The option price per share shall be fixed by the Plan Administrator. In
no event, however, shall it be less than eighty-five percent (85%) of the fair
market value per share of Common Stock on the date of the option grant.

    (2) The option price shall become immediately due upon exercise of the
option and, subject to the provisions of Article Five, Section I, and the
instrument evidencing the grant, shall be payable in one of the following
alternative forms specified below:

        (i) payment in cash or check payable to the Corporation,

        (ii) payment in shares of Common Stock held for at least six (6) months
    and valued at fair market value on the Exercise Date (as such term is
    defined below), or

       (iii) payment through a broker-dealer sale and remittance procedure
    pursuant to which the Optionee shall provide irrevocable written
    instructions (A) to a designated brokerage firm to effect the immediate sale
    of the purchased shares and remit to the Corporation, out of the sale
    proceeds available on the settlement date, sufficient funds to cover the
    aggregate option price payable for the purchased shares plus all applicable
    Federal and State income and employment taxes required to be withheld by the
    Corporation in connection with such purchase and (ii) to the Corporation to
    deliver the certificates for the purchased shares directly to such brokerage
    firm in order to complete the sale transaction.

    For purposes of this Subparagraph (2), the "Exercise Date" shall be the date
on which written notice of the option exercise is delivered to the Corporation.
Except to the extent the sale and remittance procedure is used in connection
with the exercise of the option, payment of the option price for the purchased
shares must accompany such notice.

    B.  FAIR MARKET VALUE.  The fair market value per share of Common Stock
shall be determined in accordance with the following provisions:

<PAGE>

        (1) If the Common Stock is not at the time listed or admitted to trading
    on any stock exchange but is traded on the Nasdaq National Market, the fair
    market value shall be the closing price of one share of Common Stock on the
    date in question, as such price is reported by the National Association of
    Securities Dealers through its Nasdaq system or any successor system. If
    there is no closing price for the Common Stock on the date in question, then
    the closing price on the last preceding date for which such quotation exists
    shall be determinative of fair market value.

        (2) If the Common Stock is at the time listed or admitted to trading on
    any national stock exchange, then the fair market value shall be the closing
    selling price per share of Common Stock on the date in question on the stock
    exchange determined by the Plan Administrator to be the primary market for
    the Common Stock, as such price is officially quoted in the composite tape
    of transactions on such exchange. If there is no reported sale of Common
    Stock on such exchange on the date in question, then the fair market value
    shall be the closing selling price on the exchange on the last preceding
    date for which such quotation exists.

        (3) In all other cases, the fair market value shall be determined by the
    Plan Administrator in good faith.

    C.  TERM AND EXERCISE OF OPTIONS.  Each option granted under this Article
Two shall be exercisable at such time or times and during such period as is
determined by the Plan Administrator and set forth in the stock option agreement
evidencing the grant. No such option, however, shall have a maximum term in
excess of ten (10) years from the grant date. During the lifetime of the
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable by the Optionee otherwise than by will or by the laws
of descent and distribution following the Optionee's death.

    D.  TERMINATION OF SERVICE.

    (1) Except to the extent otherwise provided pursuant to Subparagraph
(3) below, the following provisions shall govern the exercise period applicable
to any outstanding options under the Plan which are held by the Optionee at the
time of his or her cessation of Service or death:

        (i) Should an Optionee cease to remain in Service for any reason other
    than death or permanent disability, then the period for which each
    outstanding option held by such Optionee is to remain exercisable shall be
    limited to the three (3)-month period following the date of such cessation
    of Service.

        (ii) In the event such Service terminates by reason of permanent
    disability (as defined in Section 22(e)(3) of the Internal Revenue Code),
    then the period for which each outstanding option held by an Optionee is to
    remain exercisable shall be limited to the twelve (12)-month period
    following the date of such cessation of Service.

       (iii) Should an Optionee die while in Service or during the three
    (3)-month period following his or her cessation of Service, then the period
    for which each of his or her outstanding options is to remain exercisable
    shall be limited to the three (3)-year period

<PAGE>

    following the date of the Optionee's death. During such limited period, the
    option may be exercised by the personal representative of the Optionee's
    estate or by the person or persons to whom the option is transferred
    pursuant to the Optionee's will or in accordance with the laws of descent
    and distribution.

        (iv) Under no circumstances, however, shall any such option be
    exercisable after the specified expiration date of the option term.

        (v) During the limited post-termination period of exercisability, the
    option may not be exercised for more than the number of shares for which the
    option is exercisable on the date the Optionee's Service terminates. Upon
    the expiration of such limited exercise period or (if earlier) upon the
    expiration of the option term, the option shall terminate and cease to be
    exercisable.

    (2) Should (i) the Optionee's Service be terminated for misconduct
(including, but not limited to, any act of dishonesty, willful misconduct, fraud
or embezzlement) or (ii) the Optionee make any unauthorized use or disclosure of
confidential information or trade secrets of the Corporation or its parent or
subsidiaries, then in any such event all outstanding options held by the
Optionee under this Article Two shall terminate immediately and cease to be
outstanding.

    (3) The Plan Administrator shall have full power and authority to extend the
period of time for which the option is to remain exercisable following the
Optionee's cessation of Service or death from the limited period provided under
Subparagraph (1) above to such greater period of time as the Plan Administrator
shall deem appropriate under the circumstances. In no event, however, shall such
option be exercisable after the specified expiration date of the option term.

    (4) The Plan Administrator shall have complete discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to permit one or more options held by the Optionee under this
Article Two to be exercised, during the limited period of exercisability
provided under Subparagraph (1) above, not only with respect to the number of
shares for which each such option is exercisable at the time of the Optionee's
cessation of Service but also with respect to one or more subsequent
installments of purchasable shares for which the option would otherwise have
become exercisable had such cessation of Service not occurred.

    (5) For purposes of the foregoing provisions of this Section I(D) (and for
all other purposes under the Plan):

        (i) The Optionee shall (except to the extent otherwise specifically
    provided in the applicable option or issuance agreement) be deemed to remain
    in the SERVICE of the Corporation for so long as such individual renders
    services on a periodic basis to the Corporation (or any parent or subsidiary
    corporation) in the capacity of an Employee, an Outside Director or an
    independent consultant or advisor.

        (ii) The Optionee shall be considered to be an EMPLOYEE for so long as
    he or she remains in the employ of the Corporation or one or more parent or
    subsidiary

<PAGE>

    corporations, subject to the control and direction of the employer entity
    not only as to the work to be performed but also as to the manner and
    method of performance.

    E.  STOCKHOLDER RIGHTS.

    An Optionee shall have no stockholder rights with respect to any shares
covered by the option until such individual shall have exercised the option and
paid the option price for the purchased shares.

    F.  REPURCHASE RIGHTS.

    The shares of Common Stock acquired upon the exercise of options granted
under this Article Two may be subject to repurchase by the Corporation in
accordance with the following provisions:

        (1) The Plan Administrator shall have the discretion to authorize the
    issuance of unvested shares of Common Stock under this Article Two. Should
    the Optionee cease Service while holding such unvested shares, the
    Corporation shall have the right to repurchase any or all of those unvested
    shares at the option price paid per share. The terms and conditions upon
    which such repurchase right shall be exercisable (including the period and
    procedure for exercise and the appropriate vesting schedule for the
    purchased shares) shall be established by the Plan Administrator and set
    forth in the instrument evidencing such repurchase right.

        (2) All of the Corporation's outstanding repurchase rights shall
    automatically terminate, and all shares subject to such terminated rights
    shall immediately vest in full, upon the occurrence of any Corporate
    Transaction under Section III of this Article Two, except to the extent that
    (i) any such repurchase right is to be assigned to the successor corporation
    (or parent thereof) in connection with the Corporate Transaction or
    (ii) such termination is precluded by other limitations imposed by the Plan
    Administrator at the time the repurchase right is issued.

        (3) The Plan Administrator shall have the discretionary authority,
    exercisable either before or after the Optionee's cessation of Service, to
    cancel the Corporation's outstanding repurchase rights with respect to one
    or more shares purchased or purchasable by the Optionee under this Article
    Two and thereby accelerate the vesting of such shares in whole or in part at
    any time.

II.  INCENTIVE OPTIONS

    The terms and conditions specified below shall be applicable to all
Incentive Options granted under this Article Two. Incentive Options may only be
granted to individuals who are Employees of the Corporation. Options which are
specifically designated as "non-statutory" options when issued under the Plan
shall NOT be subject to such terms and conditions.

    A.  OPTION PRICE.  The option price per share of the Common Stock subject to
an Incentive Option shall in no event be less than one hundred percent (100%) of
the fair market value of such Common Stock on the grant date.

<PAGE>

    B.  DOLLAR LIMITATION.  The aggregate fair market value (determined as of
the respective date or dates of grant) of the Common Stock for which one or more
options granted to any Employee under this Plan (or any other option plan of the
Corporation or its parent or subsidiary corporations) may for the first time
become exercisable as Incentive Options during any one calendar year shall not
exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the
Employee holds two or more such options which become exercisable for the first
time in the same calendar year, the foregoing limitation on the exercisability
of such options as Incentive Options shall be applied on the basis of the order
in which such options are granted. Should the number of shares of Common Stock
for which any Incentive Option first becomes exercisable in any calendar year
exceed the applicable One Hundred Thousand Dollar ($100,000) limitation, then
the option may nevertheless be exercised in that calendar year for the excess
number of shares as a non-statutory option under the Federal tax laws.

    C.  10% STOCKHOLDER.  If any individual to whom an Incentive Option is
granted is the owner of stock (as determined under Section 424(d) of the
Internal Revenue Code) possessing ten percent (10%) or more of the total
combined voting power of all classes of stock of the Corporation or any one of
its parent or subsidiary corporations, then the option price per share shall not
be less than one hundred ten percent (110%) of the fair market value per share
of Common Stock on the grant date, and the option term shall not exceed five
(5) years measured from the grant date.

    Except as modified by the preceding provisions of this Section II, the
provisions of Articles One, Two and Four of the Plan shall apply to all
Incentive Options granted hereunder.

III.  CORPORATE TRANSACTIONS/CHANGES IN CONTROL

    A. In the event of any of the following stockholder-approved transactions to
which the Corporation is a party (a "Corporate Transaction"):

        (1) a merger or consolidation in which the Corporation is not the
    surviving entity, except for a transaction the principal purpose of which is
    to change the State of the Corporation's incorporation,

        (2) the sale, transfer or other disposition of all or substantially all
    of the assets of the Corporation in liquidation or dissolution of the
    Corporation, or

        (3) any reverse merger in which the Corporation is the surviving entity
    but in which securities possessing more than fifty percent (50%) of the
    total combined voting power of the Corporation's outstanding securities are
    transferred to holders different from those who held such securities
    immediately prior to such merger,

then the exercisability of each option outstanding under this Article Two shall
automatically accelerate so that each such option shall, immediately prior to
the specified effective date for the Corporate Transaction, become fully
exercisable with respect to the total number of shares of Common Stock at the
time subject to such option and may be exercised for all or any

<PAGE>

portion of such shares. However, an outstanding option under this Article Two
shall not so accelerate if and to the extent: (i) such option is, in
connection with the Corporate Transaction, to be assumed by the successor
corporation or parent thereof or replaced with a comparable option to
purchase shares of the capital stock of the successor corporation or parent
thereof, (ii) such option is to be replaced by a comparable cash incentive
program of the successor corporation based on the option spread at the time
of the Corporate Transaction, or (iii) the acceleration of such option is
subject to other limitations imposed by the Plan Administrator at the time of
the option grant. The determination of comparability under clause (i) or (ii)
above shall be made by the Plan Administrator, and its determination shall be
final, binding and conclusive. The Plan Administrator shall also have full
power and authority to grant options under the Plan which are to
automatically accelerate in whole or in part immediately prior to the
Corporate Transaction or upon the subsequent termination of the Optionee's
Service, whether or not those options are otherwise to be assumed or replaced
in connection with the consummation of such Corporate Transaction.

    B.  Upon the consummation of the Corporate Transaction, all outstanding
options under this Article Two shall terminate and cease to be outstanding,
except to the extent assumed by the successor corporation or its parent company.

    C.  Each outstanding option under this Article Two which is assumed in
connection with the Corporate Transaction or is otherwise to continue in effect
shall be appropriately adjusted, immediately after such Corporate Transaction,
to apply and pertain to the number and class of securities which would have been
issued to the option holder, in consummation of such Corporate Transaction, had
such person exercised the option immediately prior to such Corporate
Transaction. Appropriate adjustments shall also be made to the option price
payable per share, PROVIDED the aggregate option price payable for such
securities shall remain the same. In addition, the class and number of
securities available for issuance under the Plan following the consummation of
the Corporate Transaction shall be appropriately adjusted.

    D. The grant of options under this Article Two shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

    E.  The Plan Administrator shall have the discretionary authority,
exercisable either in advance of any actually-anticipated Change in Control or
at the time of an actual Change in Control, to provide for the automatic
acceleration of one or more outstanding options under this Article Two (and the
termination of one or more of the Corporation's outstanding repurchase rights
under this Article Two) upon the occurrence of the Change in Control. The Plan
Administrator shall also have full power and authority to condition any such
option acceleration (and the termination of any outstanding repurchase rights)
upon the subsequent termination of the Optionee's Service within a specified
period following the Change in Control.

    F.  For purposes of this Section III, a Change in Control shall be deemed to
occur in the event:

<PAGE>

        (1) any person or related group of persons (other than the Corporation
    or a person that directly or indirectly controls, is controlled by, or is
    under common control with, the Corporation) directly or indirectly acquires
    beneficial ownership (within the meaning of Rule 13d-3 of the Securities
    Exchange Act of 1934, as amended (the "1934 Act")) of securities possessing
    more than fifty percent (50%) of the total combined voting power of the
    Corporation's outstanding securities pursuant to a tender or exchange offer
    made directly to the Corporation's stockholders which the Board does not
    recommend such stockholders to accept; or

        (2) there is a change in the composition of the Board over a period of
    twenty-four (24) consecutive months or less such that a majority of the
    Board members (rounded up to the next whole number) cease, by reason of one
    or more proxy contests for the election of Board members, to be comprised of
    individuals who either (i) have been Board members continuously since the
    beginning of such period or (ii) have been elected or nominated for election
    as Board members during such period by at least a majority of the Board
    members described in clause (i) who were still in office at the time such
    election or nomination was approved by the Board.

    G. Any options accelerated in connection with the Change in Control shall
remain fully exercisable until the expiration or sooner termination of the
option term.

    H. The exercisability as incentive stock options under the Federal tax laws
of any options accelerated under this Section III in connection with a Corporate
Transaction or Change in Control shall remain subject to the dollar limitation
of Section II(B) of this Article Two.

IV.  CANCELLATION AND REGRANT OF OPTIONS

    The Plan Administrator shall have the authority to effect, at any time and
from time to time, with the consent of the affected Optionees, the cancellation
of any or all outstanding options under this Article Two (including outstanding
options under the Predecessor Plans incorporated into this Plan) and to grant in
substitution new options under the Plan covering the same or different numbers
of shares of Common Stock but having an option price per share not less than
eighty-five percent (85%) of the fair market value of the Common Stock on the
new grant date (or one hundred percent (100%) of such fair market value in the
case of an Incentive Option or, in the case of an Incentive Option granted to a
10% Stockholder, not less than one hundred and ten percent (110%) of fair market
value).

V.  CASH-OUT OF OPTIONS

    A. One or more officers of the Corporation may, in the Plan Administrator's
sole discretion, be granted limited cash-out rights in connection with their
outstanding options under the Plan. Upon the occurrence of a Hostile Take-Over,
each outstanding option with such a limited cash-out right in effect for at
least six (6) months shall automatically be cancelled, to the extent such option
is at the time exercisable for fully-vested shares of Common Stock. The Optionee
shall in return be entitled to a cash distribution from the Corporation in an
amount equal to the excess of (i) the Take-Over Price of the vested shares of
Common Stock at the time subject to the cancelled option (or cancelled portion
of such option) over (ii) the aggregate exercise price

<PAGE>

payable for such shares. The cash distribution payable upon such cancellation
shall be made within five (5) days following the consummation of the Hostile
Take-Over. Neither the approval of the Plan Administrator nor the consent of
the Board shall be required in connection with such option cancellation and
cash distribution.

    B.  For purposes of Section V(A), the following definitions shall be in
effect:

        (1) A Hostile Take-Over shall be deemed to occur in the event (i) any
    person or related group of persons (other than the Corporation or a person
    that directly or indirectly controls, is controlled by, or is under
    common control with, the Corporation) directly or indirectly acquires
    beneficial ownership (within the meaning of Rule 13d-3 of the 1934 Act)
    of securities possessing more than fifty percent (50%) of the total
    combined voting power of the Corporation's outstanding securities
    pursuant to a tender or exchange offer made directly to the Corporation's
    stockholders which the Board does not recommend such stockholders to accept
    AND (ii) more than fifty percent (50%) of the securities so acquired in such
    tender or exchange offer are accepted from holders other than officers and
    directors of the Corporation subject to the short-swing profit restrictions
    of Section 16 of the 1934 Act.

        (2) The Take-Over Price per share shall be deemed to be equal to the
    GREATER of (i) the fair market value per share on the date of cancellation,
    as determined pursuant to the valuation provisions of Section I(B) of this
    Article Two, or (ii) the highest reported price per share paid in effecting
    such Hostile Take-Over. However, if the cancelled option is an Incentive
    Option, the Take-Over Price shall not exceed the clause (i) price per share.

    C.  The shares of Common Stock subject to any option cancelled for an
apprecia tion distribution pursuant to this Section V shall NOT be available for
subsequent option grants under the Plan.

                                 ARTICLE THREE
                            AUTOMATIC OPTION GRANTS

I.  GRANT OF AUTOMATIC OPTIONS

    Outside Directors shall automatically be granted non-statutory options (the
"Automatic Option Grants") to purchase the number of shares of Common Stock set
forth below (subject to adjustment under Article I, Section V(D)) on the dates
set forth below:

        A.  INITIAL GRANTS.  Each individual who is serving as an Outside
    Director on January 23, 1995, shall, on that date, automatically be granted
    a non-statutory stock option to purchase fifteen thousand (15,000) shares of
    Common Stock. A person who is first elected by the stockholders or appointed
    by the Board as an Outside Director (and who is not already a member of the
    Board) shall, on the date such person becomes an Outside Director (or, if
    later, on the next trading day), automatically receive an option to purchase
    fifteen thousand (15,000) (twenty-four thousand (24,000) for an Outside
    Directorfirst appointed on or after May 25, 2000)(4) shares of Common Stock.
    (Options granted under this Subparagraph (1) are referred to below as
    "Initial Automatic Option Grants.")

        B.  ANNUAL GRANTS.  On October 24, 1996, each individual who then is
    serving as an Outside Director and who has so served for not less than
    ninety (90) days shall, on that date, automatically be granted a
    non-statutory stock option to purchase three thousand (3,000) shares of
    Common Stock. On the date of each Annual Stockholders' Meeting, commencing
    with the 1997 Annual Stockholders' Meeting, each individual who thereafter
    will continue serving as an Outside Director and who has so served for not
    less than ninety (90) days shall, on that date, automatically be granted a
    non-statutory stock option to purchase three thousand (3,000) shares of
    Common Stock. Commencing with the 2000 Annual Stockholders' Meeting, each
    individual who thereafter will continue serving as an Outside Director and
    who has so served for not less than ninety (90) days shall, on that date,
    automatically be granted a non-statutory stock option to purchase eight
    thousand (8,000) shares of Common Stock.(5) (Options granted under this
    Subparagraph (2) are referred to below as "Annual Automatic Option Grants.")

II.  TERMS AND CONDITIONS

    The terms and conditions applicable to each Automatic Option Grant shall be
as follows:

        A.  PRICE.  The option price per share shall be equal to one hundred
    percent (100%) of the fair market value of one share of Common Stock on the
    date of grant.

------------------------
(4)  Authorized by the Board in April 2000, subject to approval by the
     stockholders at the 2000 Annual Stockholders' Meeting.

(5)   Authorized by the Board in April 2000, subject to approval by the
     stockholders at the 2000 Annual Stockholders' Meeting.

<PAGE>

        B.  TERM.  The options shall have terms of ten (10) years, measured from
    the date of grant, and shall be immediately exercisable. However, any
    non-vested shares purchased under the option shall be subject to repurchase
    by the Corporation, at the exercise price paid per share, upon the Outside
    Director's cessation of Board service prior to vesting in those shares.

        C.  VESTING.

        (1) The shares subject to each Initial Automatic Option Grant shall
    vest, and the Corporation's repurchase right with respect to those shares
    shall lapse, with respect to twenty percent (20%) of the optioned shares
    upon completion of twelve (12) months of Board service from the date of
    grant, and the remainder of the optioned shares in forty-eight (48) equal
    monthly installments. The shares subject to each Annual Automatic Option
    Grant shall vest, and the Corporation's repurchase right with respect to
    those shares shall lapse, with respect to thirty-three and one-third percent
    (33 1/3%) of the optioned shares upon completion of twelve (12) months of
    Board service from the date of grant, and the remainder of the optioned
    shares in twenty-four (24) equal monthly installments. Vesting of the option
    shares shall be subject to acceleration as provided below. In no event,
    however, shall any additional option shares vest after the Optionee's
    cessation of Board service.

        (2) All Automatic Option Grants made on or after the date of the 2000
    Annual Stockholder's meeting shall vest, and the Corporation's repurchase
    right with respect to those shares shall lapse, with respect to twenty-five
    percent (25%) of the optioned shares upon completion of twelve (12) months
    of Board service from the date of grant, and the remainder of the optioned
    shares in thirty-six (36) equal monthly installments.(6)

        D.  PAYMENT.  Upon exercise of the option, the option price for the
    purchased shares shall become payable immediately in cash or in shares of
    Common Stock that the optionee has held for at least six (6) months. Payment
    may also be made by delivery of a properly executed exercise notice together
    with irrevocable instructions to a broker to promptly deliver to the
    Corporation the amount of sale or loan proceeds to pay the option price.

        E.  CESSATION.

        (1) In the event the optionee ceases to provide services to the
    Corporation or its subsidiaries as a director for any reason other than
    death or disability, each outstanding option may be exercised, within the
    term of the option, for a period of three (3) months after the date of such
    cessation to the extent that it was exercisable upon the date that such
    services cease.

        (2) In the event the optionee ceases to provide such services by reason
    of permanent disability, each outstanding option may be exercised, within
    the term of the option, for a period of twelve (12) months after the date
    of such cessation to the extent that it was exercisable upon the date that
    such services cease.

------------------------
(6)  Authorized by the Board in April 2000, subject to approval by the
     stockholders at the 2000 Annual Stockholders' Meeting.

<PAGE>

        (3) Should an Outside Director die while in service or during the three
    (3)-month period following his or her cessation of Board service, then each
    outstanding option may be exercised, within the term of the option, for a
    period of three (3) years following the date of the optionee's death. In the
    case of death, the option may be exercised within such period by the estate
    or heirs of the optionee.

III.  CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

    A.  CORPORATE TRANSACTION.  In the event of any Corporate Transaction as
defined in Article Two, Section III(A), the shares of Common Stock at the time
subject to each outstanding option but not otherwise vested shall automatically
vest in full so that each such option shall, immediately prior to the specified
effective date for the Corporate Transaction, become fully exercisable for all
of the shares of Common Stock at the time subject to that option and may be
exercised for all or any portion of such shares as fully-vested shares of Common
Stock. Immediately following the consummation of the Corporate Transaction, each
Automatic Option Grant under the Plan shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation or its
parent company.

    B.  CHANGE IN CONTROL.  In connection with any Change in Control of the
Corporation, the shares of Common Stock at the time subject to each outstanding
option but not otherwise vested shall automatically vest in full so that each
such option shall, immediately prior to the specified effective date for the
Change in Control, become fully exercisable for all of the shares of Common
Stock at the time subject to that option and may be exercised for all or any
portion of such shares as fully-vested shares of Common Stock. Each such option
shall remain fully exercisable for the option shares which vest in connection
with the Change in Control until the expiration or sooner termination of the
option term or the cash-out of the option in accordance with Subsection
(C) below.

    C.  HOSTILE TAKE-OVER.  Upon the occurrence of a Hostile Take-Over, the
optionee shall have a thirty (30)-day period in which to surrender to the
Corporation each Automatic Option Grant held by him or her under this Plan for a
period of at least six (6) months. The optionee shall in return be entitled to a
cash distribution from the Corporation in an amount equal to the excess of
(i) the Take-Over Price of the shares of Common Stock at the time subject to the
surrendered option (whether or not the optionee is otherwise at the time vested
in those shares) over (ii) the aggregate exercise price payable for such shares.
Such cash distribution shall be paid within five (5) days following the
surrender of the option to the Corporation. No approval or consent of the Board
shall be required in connection with such option surrender and cash
distribution.

    D.  REUSE OF SHARES.  The shares of Common Stock subject to each option
surrendered in connection with the Hostile Take-Over shall NOT be available for
subsequent option grant under this Plan.

    E.  NON-TRANSFERABILITY.  During the lifetime of the optionee, each
Automatic Option Grant, together with the limited stock appreciation right
pertaining to such option, shall be exercisable

<PAGE>

only by the optionee and shall not be assignable or transferable by the
optionee other than a transfer of the option effected by will or by the laws
of descent and distribution following the optionee's death.

<PAGE>
                                  ARTICLE FOUR
                             STOCK ISSUANCE PROGRAM

I.  TERMS AND CONDITIONS OF STOCK ISSUANCES

    Shares may be issued under the Stock Issuance Program through direct and
immediate purchases without any intervening stock option grants. The issued
shares shall be evidenced by a Stock Issuance Agreement (the "Issuance
Agreement") that complies with the terms and conditions of this Article Four.

    A.  CONSIDERATION.

    (1) Shares of Common Stock drawn from the Corporation's authorized but
unissued shares of Common Stock (the "Newly Issued Shares") shall be issued
under the Plan for one or more of the following items of consideration which the
Plan Administrator may deem appropriate in each individual instance:

        (i) cash or check payable to the Corporation;

        (ii) a promissory note payable to the Corporation's order in one or more
    installments, which may be subject to cancellation in whole or in part upon
    terms and conditions established by the Plan Administrator; or

       (iii) past services rendered to the Corporation or any parent or
    subsidiary corporation.

    (2) Newly Issued Shares may, in the absolute discretion of the Plan
Administrator, be issued for consideration with a value less than one-hundred
percent (100%) of the fair market value of the issued shares, but in no event
less than eighty-five percent (85%) of such fair market value. Fair market value
shall be determined in accordance with Article Two, Section I(B).

    (3) Shares of Common Stock reacquired by the Corporation and held as
treasury shares (the "Treasury Shares") may be issued under the Plan for such
consideration (in whatever form) as the Plan Administrator may deem appropriate.
Accordingly, such Treasury Shares may, in lieu of any cash consideration, be
issued subject to such vesting requirements tied to the Participant's period of
future Service or the Corporation's attainment of specified performance
objectives as the Plan Administrator may establish at the time of issuance.

    B.  VESTING PROVISIONS.

    (1) Shares of Common Stock issued under the Plan may, in the absolute
discretion of the Plan Administrator, be fully and immediately vested upon
issuance or may vest in one or more installments over the Participant's period
of Service (as such term is defined in Section I(D)(5) of Article Two). The
elements of the vesting schedule applicable to any unvested shares of Common
Stock issued under the Plan, including the period of Service to be completed or
the performance objectives to be achieved, the number of installments, the
interval between installments, and the effect which death, disability or other
event is to have upon the vesting

<PAGE>

schedule, shall be determined by the Plan Administrator and incorporated into
the Issuance Agreement executed by the Corporation and the Participant at the
time such unvested shares are issued.

    (2) The Participant shall have full stockholder rights with respect to any
shares of Common Stock issued to him or her under the Plan, whether or not his
or her interest in those shares is vested. Accordingly, the Participant shall
have the right to vote such shares and to receive any regular cash dividends
paid on such shares. Any new, additional or different shares of stock or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to his or her unvested
shares by reason of any stock dividend, stock split, reclassification of Common
Stock or other similar change in the Corporation's capital structure or by
reason of any Corporate Transaction under Section II of this Article Four shall
be issued, subject to (i) the same vesting requirements applicable to his or her
unvested shares and (ii) such escrow arrangements as the Plan Administrator
shall deem appropriate.

    (3) Should the Participant cease to remain in Service while holding one or
more unvested shares of Common Stock under the Plan, then those shares shall be
immediately surrendered to the Corporation for cancellation, and the Participant
shall have no further stockholder rights with respect to those shares. To the
extent the surrendered shares were previously issued to the Participant for
consideration paid in cash or cash equivalent (including the Participant's
purchase-money promissory note), the Corporation shall repay to the Participant
the cash consideration paid for the surrendered shares and shall cancel the
principal balance of any outstanding purchase-money note of the Participant to
the extent attributable to such surrendered shares. The surrendered shares may,
at the Plan Administrator's discretion, be retained by the Corporation as
Treasury Shares or may be retired to authorized but unissued share status.

    (4) The Plan Administrator may in its discretion elect to waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to such shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

II.  CORPORATE TRANSACTIONS/CHANGES IN CONTROL

    A. In the event of a Corporate Transaction to which the Corporation is a
party (as defined in Section III of Article Two), then all unvested shares of
Common Stock shall immediately vest in full, except to the extent the Plan
Administrator imposes limitations in the Issuance Agreement which preclude such
accelerated vesting in whole or in part.

    B.  The Plan Administrator shall have the discretionary authority,
exercisable either in advance of any actually-anticipated Change in Control (as
defined in Section III of Article Two) or at the time of an actual Change in
Control, to provide for the immediate and automatic vesting

<PAGE>

of one or more unvested shares outstanding under this Article Four at the
time of such Change in Control. The Plan Administrator shall also have full
power and authority to condition any such accelerated vesting upon the
subsequent termination of the Optionee's Service within a specified period
following the Change in Control.

III.  TRANSFER RESTRICTIONS/SHARE ESCROW

    A. Unvested shares may, in the Plan Administrator's discretion, be held in
escrow by the Corporation until the Participant's interest in such shares vests
or may be issued directly to the Participant with restrictive legends on the
certificates evidencing such unvested shares. To the extent an escrow
arrangement is used, the unvested shares and any securities or other assets
issued with respect to such shares (other than regular cash dividends) shall be
delivered in escrow to the Corporation to be held until the Participant's
interest in such shares (or other securities or assets) vests. Alternatively, if
the unvested shares are issued directly to the Participant, a restrictive legend
shall be placed on the certificates for such shares and shall read substantially
as follows:

       "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE UNVESTED AND ARE
       ACCORDINGLY SUBJECT TO (I) CERTAIN TRANSFER RESTRICTIONS AND TO
       (II) CANCELLATION OR REPURCHASE IN THE EVENT THE REGISTERED HOLDER (OR
       HIS/HER PREDECESSOR IN INTEREST) CEASES TO REMAIN IN THE CORPORATION'S
       SERVICE. SUCH TRANSFER RESTRICTIONS AND THE TERMS AND CONDITIONS OF
       SUCH CANCELLATION OR REPURCHASE ARE SET FORTH IN A STOCK ISSUANCE
       AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER (OR
       HIS/HER PREDECESSOR IN INTEREST) DATED             , 19  , A
       COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE CORPORATION."

    B.  The Participant shall have no right to transfer any unvested shares of
Common Stock issued to him or her under the Plan. For purposes of this
restriction, the term "transfer" shall include (without limitation) any sale,
pledge, assignment, encumbrance, gift, or other disposition of such shares,
whether voluntary or involuntary. Upon any such attempted transfer, the unvested
shares shall immediately be cancelled, and neither the Participant nor the
proposed transferee shall have any rights with respect to those shares. However,
the Participant shall have the right to make a gift of unvested shares acquired
under the Plan to his or her spouse or issue, including adopted children, or to
a trust established for such spouse or issue, provided the donee of such shares
delivers to the Corporation a written agreement to be bound by all the
provisions of the Plan and the Issuance Agreement applicable to the gifted
shares.

                                  ARTICLE FIVE
                                 MISCELLANEOUS

I.  LOANS OR INSTALLMENT PAYMENTS

    A. The Plan Administrator may, in its discretion, assist any employee
(including an Optionee or Participant who is an officer or director of the
Corporation) in the exercise of one or more options granted to such Optionee
under the Article Two Discretionary Option Grant Program or the purchase of one
or more shares issued to such Participant under the Article Four Stock Issuance
Program, including the satisfaction of any Federal and State income and
employment tax obligations arising therefrom by (i) authorizing the extension of
a loan from the Corporation to such Optionee or Participant or (ii) permitting
the Optionee or Participant to pay the option price or purchase price for the
purchased Common Stock in installments over a period of years. The terms of any
loan or installment method of payment (including the interest rate and terms of
repayment) shall be upon such terms as the Plan Administrator specifies in the
applicable option or issuance agreement or otherwise deems appropriate under the
circumstances. Loans and installment payments may be granted with or without
security or collateral (other than to individuals who are consultants or
independent contractors, in which event the loan must be adequately secured by
collateral other than the purchased shares). However, the maximum credit
available to the Optionee or Participant may not exceed the option or purchase
price of the acquired shares (less the par value of such shares) plus any
Federal and State income and employment tax liability incurred by the Optionee
or Participant in connection with the acquisition of such shares.

    B.  The Plan Administrator may, in its absolute discretion, determine that
one or more loans extended under this financial assistance program shall be
subject to forgiveness by the Corporation in whole or in part upon such terms
and conditions as the Plan Administrator may deem appropriate.

II.  AMENDMENT OF THE PLAN AND AWARDS

    A. The Board has complete and exclusive power and authority to amend or
modify the Plan (or any component thereof) in any or all respects whatsoever.
However, no such amendment or modification may adversely affect the rights
and obligations of an Optionee with respect to options at the time
outstanding under the Plan, nor adversely affect the rights of any
Participant with respect to Common Stock issued under the Plan prior to such
action, unless the Optionee or Participant consents to such amendment. The
Board may not, without the approval of the Corporation's stockholders, amend
the Plan to (i) materially increase the maximum number of shares issuable
under the Plan in the aggregate or to any single individual (except for
permissible adjustments under Article One, Section V(D)) or (ii) materially
modify the eligibility requirements for participation in the Plan.

    B.  Options to purchase shares of Common Stock may be granted under the
Plan, and shares of Common Stock may be issued under the Stock Issuance Program,
which are in both instances

<PAGE>

in excess of the number of shares then available for issuance under the Plan,
provided any excess shares actually issued under the Plan are held in escrow
until stockholder approval is obtained for a sufficient increase in the
number of shares available for issuance under the Plan. If such stockholder
approval is not obtained within twelve (12) months after the date the first
such excess option grants or excess share issuances are made, then (i) any
unexercised excess options shall terminate and cease to be exercisable and
(ii) the Corporation shall promptly refund the purchase price paid for any
excess shares actually issued under the Plan and held in escrow, together
with interest (at the applicable Short Term Federal Rate) for the period the
shares were held in escrow.

III.  EFFECTIVE DATE AND TERM OF PLAN

    A. The Plan was initially adopted by the Board on January 11, 1992, and
approved by the Corporation's stockholders on April 25, 1992. The Board
subsequently restated the Plan, effective on July 31, 1992, to serve as the
successor to the Predecessor Plans and again restated the Plan on May 25, 1993,
to include certain provisions in connection with the initial public offering of
the Common Stock and to increase the number of shares issuable under the Plan by
82,276 shares (after giving effect to the 1-for-1.6 reverse stock split approved
by the Board on the same date). On April 24, 1994, the Board adopted a
restatement of the Plan which (i) increased the number of shares of Common Stock
issuable thereunder by an additional 500,000 shares and (ii) imposed a
limitation on the maximum number of shares for which any one individual
participating in the Plan may be granted stock options or direct stock issuances
after December 31, 1993. The 1994 restatement was approved by the Corporation's
stockholders at the 1994 Annual Meeting and became effective when adopted by the
Board. On January 23, 1995, the Board adopted amendments to the Plan which added
the Initial Automatic Option Grants to the Plan and increased the number of
shares of Common Stock issuable under the Plan by an additional 300,000 shares.
The 1995 restatement was approved by the Corporation's stockholders at the 1995
Annual Meeting and became effective when adopted by the Board. In January 1996,
the Board adopted a restatement of the Plan which increased the number of shares
of Common Stock issuable thereunder by an additional 300,000 shares to 1,880,000
shares. The January 1996 restatement was approved by the Corporation's
stockholders at the 1996 Annual Meeting and became effective when adopted by the
Board. In October 1996, the Board adopted a restatement of the Plan which
increased the number of shares of Common Stock issuable thereunder by an
additional 200,000 shares to 2,080,000 shares and provided for the Annual
Automatic Option Grants. The October 1996 restatement was approved by the
Corporation's stockholders at the 1997 Annual Meeting and became effective when
adopted by the Board. Subject to the foregoing limitations, the Plan
Administrator may grant options under the Plan at any time before the date fixed
herein for termination of the Plan.

    B.  This Plan shall serve as successor to the Predecessor Plans and no
further option grants shall be made under the Predecessor Plans from and after
July 31, 1992. Each option issued and outstanding under the Predecessor Plans
immediately prior to July 31, 1992, shall be incorporated into this Plan and
treated as an outstanding option under this Plan, but each such option shall
continue to be governed solely by the terms and conditions of the instrument
evidencing such grant and nothing in this Plan shall be deemed to affect or
otherwise modify the

<PAGE>

rights or obligations of the holders of such options with respect to their
acquisition of shares of Common Stock thereunder.

    C.  The sale and remittance procedure authorized for the exercise of
outstanding options under this Plan shall be available for all options
granted under this Plan and for all non-statutory options outstanding under
the Predecessor Plans and incorporated into this Plan. The Plan Administrator
may also allow such procedure to be used in connection with one or more
disqualifying dispositions of shares acquired under Incentive Options granted
under the Predecessor Plans.

    D. The option/vesting acceleration provisions of Section III of Article Two
and Section II of Article Four relating to Corporate Transactions and Changes in
Control may, in the Plan Administrator's discretion, be extended to one or more
stock options which are outstanding under the Predecessor Plans but which do not
otherwise provide for such acceleration.

    E.  The Plan shall terminate upon the EARLIER of (i) January 10, 2002, or
(ii) the date on which all shares available for issuance under the Plan shall
have been issued or cancelled pursuant to the exercise, surrender or cash-out of
the options granted under the Discretionary Option Grant Program or Automatic
Option Grant Program, or the issuance of shares (whether vested or unvested)
under the Stock Issuance Program. If the date of termination is determined under
clause (i) above, then all option grants and unvested stock issuances
outstanding on such date shall thereafter continue to have force and effect in
accordance with the provisions of the instruments evidencing such grants or
issuances.

IV.  USE OF PROCEEDS

    Cash proceeds received by the Corporation from the sale of shares under the
Plan shall be used for general corporate purposes.

V.  REGULATORY APPROVALS

    A. The implementation of the Plan, the granting of any option under the
Plan, the issuance of any shares under the Stock Issuance Program, and the
issuance of Common Stock upon the exercise or surrender of the option grants
made hereunder shall be subject to the Corporation's procurement of all
approvals and permits required by regulatory authorities having jurisdiction
over the Plan, the options granted under it, and the Common Stock issued
pursuant to it.

    B.  No shares of Common Stock or other assets shall be issued or delivered
under this Plan unless and until there shall have been compliance with all
applicable requirements of Federal and State securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements

                                 CONDUCTUS, INC.
                        1994 EMPLOYEE STOCK PURCHASE PLAN
                   (AMENDED AND RESTATED EFFECTIVE MAY 25, 2000)

1.       PURPOSE
         The Conductus, Inc. 1994 Employee Stock Purchase Plan (the "Plan") is
intended to provide an opportunity to participate in the ownership of Conductus,
Inc. (the "Company") for eligible employees of the Company and such other
companies ("Participating Companies") as the Board of Directors of the Company
(the "Board") shall from time to time designate; PROVIDED that each such company
shall qualify as a "parent corporation" or "subsidiary corporation" as defined
in Section 425(e) and (f) of the Internal Revenue Code of 1986 (the "Code"), (a
"Corporate Affiliate") on the first day of the relevant Offering Period. It is
further intended the Plan shall qualify as an "employee stock purchase plan" as
defined in Section 23 of the Code.

2.       ADMINISTRATION

         (a) ADMINISTRATIVE BODY. The Plan shall be administered by a committee
or committees (the Committee") appointed by the Board. The Committee shall have
full authority to interpret and construe any provision of the Plan and to adopt
such rules and regulations for administering the Plan as it may deem necessary.
Decisions of the Committee shall be final and binding on all parties who have an
interest in the Plan.

         (b) RULE 16B-3 LIMITATIONS. Notwithstanding the provisions of
Subsection 2(a), in the event that Rule 16b-3 promulgated under the Securities
Exchange Act of 1934, as amended, or any successor provision ("Rule 16b-3")
provides specific requirements for the administrators of plans of this type, the
Plan shall be only administered by such a body and in such a manner as shall
comply with the applicable requirements of Rule 16b-3. Unless permitted by Rule
16b-3, no discretion concerning decisions regarding the Plan shall be afforded
to any committee or person that is not "disinterested" as that term is used in
Rule 16b-3.

3.       EFFECTIVE DATE AND TERM OF PLAN

         (a) EFFECTIVE DATE. The Plan shall become effective August 1, 1994, but
no shares of Common Stock shall be issued under the Plan and no purchase rights
granted under the Plan shall be exercisable before the Plan is approved by the
holders of at least a majority of the Company's voting stock represented and
voting at a duly-held meeting at which a quorum is present. If such shareholder
approval is not obtained, then any purchase rights previously granted under the
Plan shall terminate and no further purchase rights shall be granted.

<PAGE>

         (b) TERMINATION OF THE PLAN. The Plan shall continue in effect until
the date on which all shares available for issuance under the Plan shall have
been issued unless earlier terminated pursuant to Section 10 or 11.

4.       STOCK SUBJECT TO THE PLAN

         (a) NUMBER OF SHARES. The stock subject to the plan shall be shares

subject to the Plan, or subject to any purchase right granted under the Plan
(through merger, consolidation, reorganization, recapitalization, stock
dividend, split-up, combination of shares, exchange of shares, change in
corporate structure, or otherwise), appropriate adjustments shall be made as
to (i) the class and maximum number of shares subject to the Plan, (ii) the
class and maximum number of shares purchasable by each participant per
Purchase Period, and (iii) the class and number of shares and price per share
of stock subject to outstanding purchase rights in order to prevent the

the Plan will begin on August 1, 1994 and end on May 31, 1995.

6.       PURCHASE PERIODS

Offering Period (unless otherwise determined by the Committee); PROVIDED that

<PAGE>

collected in the initial Offering/Purchase Period shall be applied to the
purchase of Common Stock on May 31, 1995, the months after the commencement
of the initial Offering/Purchase Period. The Committee shall designate the
final day of each Purchase Period so as to facilitate administration of the
Plan. No two Purchase Periods shall run concurrently.

7.       ELIGIBILITY AND PARTICIPATION

         (a) GENERAL RULES. Each employee of the Company or any of the
Participating Companies who is employed on a full-time basis requiring more than
twenty (20) hours of service per week for more than five (5) months per calendar
year shall be an eligible employee on any date if, on that date her or she has
completed 90 days of service with the Company or any of the Participating
companies. An employee who has become an eligible employee before he first day
of an Offering Period shall be eligible to participate in the Plan during that
Offering Period. An employee who is ineligible on the first day of the Offering
Period may participate in the subsequent semi-annual Purchase Period within the
Offering Period if he or she satisfies the minimum service requirements before
the first day of such Purchase Period; PROVIDED, if an employee is eligible to
participate on August 1, 1994, but does not enroll in the Plan by August 12,
1994, or the employee first becomes eligible to participate in the Plan after
August 1, 1994, but before January 2, 1995, the employee may participate in the
Plan effective January 2, 1995. Each eligible employee may become a participant
with respect to a purchase Period by executing such instruments as the Committee
may specify and delivering them to such persons and at such time prior to the
first day of that Purchase Period as the Committee may specify.

         (b)     FIVE PERCENT OWNER.  Under no circumstances shall purchase
rights be granted under the Plan to any employee if such individual would,
immediately after the grant, own (within he meaning of Code Section 424(d)),
or hold outstanding options or other rights to purchase, stock possessing
five percent (5%) or more of he total combined voting power or value of all
classes of stock of the Company or any Corporate Affiliate.

8.       PURCHASE RIGHTS

         Each participant shall be granted a separate purchase right for each
Offering Period in which the individual participates. The purchase right shall
be granted on the date which such individual first joins the offering Period and
shall be automatically exercised on each Purchase Date within the Offering
Period; PROVIDED, with respect to the initial Offering/Purchase Period, each
employee who is eligible to participate on August 1, 1994, will be granted a
purchase right on that date. Exercise of this purchase right shall be subject to
the employee's subsequent enrollment in the Plan by August 12, 1994. Each
employee who becomes a participant in the Plan on January 2, 1995, shall be
granted a purchase right on that date.

         Purchase rights shall be evidenced by instruments in such form as the
Committee may from time to time approve, and shall conform to the following
terms and conditions:

<PAGE>

         (a) PURCHASE PRICE. The Purchase Price of each share purchased on any
date within an Offering Period shall be the LOWER of (i) eighty-five percent
(85%) of the fair market value per share of the Company's Common Stock on the
first day of the Offering Period, (or, if a participant joins an Offering Period
after the first day of that Offering Period, the GREATER of eighty-five percent
(85%) of the fair market value per share of the Company's Common Stock on the
first day of the Offering Period, or eighty-five percent (85%) of the fair
market value per share on the day the participant joins the Offering Period), or
(ii) eighty-five percent (85%) of the fair market value per share of the
Company's Common Stock on the Purchase Date.

         (b) FAIR MARKET VALUE. For purposes of the Plan, the fair market value
per share of the Company's Common Stock on any relevant day shall be determined
in accordance with the following provisions:

                  (i) If the Common Stock is not at the time listed or admitted
to trading on any stock exchange but is traded on the NASDAQ National Market,
the fair market value shall be the closing selling price of one share of Common
Stock on the date in question, as reported by the National Association of
Securities Dealers through its Nasdaq system or any successor system. If there
is no closing selling price for the Common Stock on the date in question, then
the closing selling price on the last preceding date for which such quotation
exists shall be determinative of fair market value.

                  (ii) If the Common Stock is at the time listed or admitted to
trading on any national stock exchange, then the fair market value shall be the
closing selling price per share of Common Stock on the date in question on the
stock exchange that the Committee determines to be the primary market for such
Common Stock, as such price is officially quoted in the composite tape of
transactions on such exchange. If there is no reported sale of Common Stock on
such exchange on the date in question, then the fair market value shall be the
closing selling price on the exchange on the last preceding date for which such
quotation exists.

         (c) PAYROLL DEDUCTIONS. Payment for Common Stock under the Plan shall
be effected by means of the participant's authorized payroll deductions. Such
deductions shall begin with the first pay day following the participant's entry
date into the Offering Period and shall (unless sooner terminated by the
participant) remain in effect for successive Purchase Periods and Offering
Periods; PROVIDED, payroll deductions for the initial Offering Period will begin
with the payroll period ending August 12, 1994. A participant may elect a
percentage of the participant's compensation paid during the Purchase Period, in
one percent (1%) increments (not to exceed ten percent (10%)), to be contributed
to the Plan. Compensation for this purpose will include total cash earnings paid
by the Company or a Participating Company, including bonuses, overtime and
commissions and elective contributions that are not includible in income under
Internal Revenue Code Sections 125, 402(a)(8), 401(h) or 403(b).

         (d) NUMBER OF SHARES. No participant may purchase more than 2,500
shares of Common Stock in any Purchase Period; PROVIDED, for the initial
ten-month Offering Period, no participant may purchase more than 4,250 shares of
Common Stock.

<PAGE>

         (e) TERMINATION OF OR CHANGES TO PAYROLL DEDUCTIONS. Unless a
participant has irrevocably elected otherwise, the participant may terminate
payroll deductions at any time by filing the appropriate form with the Committee
subject to such advance notice as the Committee may require. If a participant
terminates payroll deductions, he or she cannot rejoin that particular Purchase
Period at any later date. All further payroll deductions will cease, and any
payroll deductions previously collected from the participant and not previously
applied to the purchase of Common Stock during that Purchase Period shall, at
the participant's election, immediately be refunded or held for the purchase of
shares on the next Purchase Date immediately following such termination. If no
such election is made, then such funds shall be refunded as soon as possible
after the Purchase Date. A participant may increase or decrease the rate of
payroll deductions twice per Purchase Period subject to such advance notice as
the Committee may require. The Committee shall determine, in its discretion,
when such rate change shall become effective.

         (f) TERMINATION OF EMPLOYMENT. If a participant ceases to be employed
by the Company or a Participation Company for any reason, including death or
disability, prior to the end of a Purchase Period, the participant's purchase
right shall terminate, and any payroll deductions previously collected from the
participant and not previously applied to the purchase of Common Stock during
that Purchase Period shall, at the participant's election (or at the election of
the estate of the deceased participant) immediately be paid to the participant
or the participant's personal representative, or held for purchase of shares on
the next Purchase Date immediately following such termination. If no such
election is made, then such funds shall be refunded as soon as possible after
the Purchase Date. The Committee may provide, on a uniform basis with respect to
any Purchase Period, that an employee who is on a leave of absence will be
deemed to have terminated employment after a specified period.

         (g) PRORATION OF PURCHASE RIGHTS. If the total number of shares of
Common Stock for which purchase rights are to be granted on any date in
accordance with the terms of the Plan exceed the number of shares then remaining
available under the Plan (after deduction of all shares for which purchase right
have been exercised or are then outstanding), the committee shall make a pro
rata allocation of the shares remaining available in as near as uniform a manner
as shall be practicable and as it shall deem equitable. The Committee shall give
written notice of such allocation to each participant affected thereby.

         (h) EXERCISE. Each purchase right shall be exercised automatically on
the Purchase Date for the full number of purchasable shares, unless the purchase
right has been previously terminated pursuant to Section 8(e) or 8(f).

         (i) ASSIGNABILITY. Subject to Section 9, purchase rights under the Plan
shall not be assignable or transferable by the participant other than by will or
by the laws of descent and distribution and during the life of the participant
shall be exercisable only by the participant.

         (j) RIGHTS AS STOCKHOLDER. A participant shall have no rights as a
stockholder with respect to shares covered by any purchase right granted under
the Plan until the

<PAGE>

purchase right is exercised. No adjustments will be made for dividend or
other rights for which the record date is prior to the date of exercise.

         (k) ACCRUAL LIMITATIONS. No purchase right shall permit the rights of a
participant to purchase stock under all "employee stock purchase plans" (as
defined in Section 423 of the Code) of the Company or a Corporate Affiliate to
accrue at a rate that exceeds $25,000 of fair market value of such stock
(determined at the time such purchase right is granted) for each calendar year
in which such purchase right is outstanding at any time.

         (l) REGULATORY APPROVAL. The implementation of the Plan, the granting
of any purchase right under the Plan, and the issuance of Common Stock upon the
exercise of any such purchase right shall be subject to the Company's compliance
with all applicable requirements of the 1933 Act, all applicable listing
requirements of any securities exchange on which the Common Stock is listed and
all other applicable requirements established by law or regulation.

         (m) OTHER PROVISIONS. Instruments evidencing purchase rights may
contain such other provisions, not inconsistent with the Plan, as the Committee
deems advisable.

9.       DESIGNATION OF BENEFICIARY

         A participant may file a written designation of a beneficiary who is to
receive shares and cash, if any, credited on behalf of the participant under the
Plan in the event of the death of a participant and in the absence of a
beneficiary validly designated under the Plan who is living at the time of such
participant's death, the Company shall deliver such shares and/or cash to the
executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company shall deliver such shares and/or cash to the participant's spouse or
if no spouse is living, to the children of the participant in equal shares.

10.      CORPORATE TRANSACTIONS

         (a) TERMINATION. In the event the disposition of all or substantially
all of the assets or outstanding capital stock of the issuer by means of a sale,
merger, reorganization, or liquidation, (a "Corporate Transaction") each
purchase right under this Plan, unless assumed pursuant to a written agreement
by the successor corporation or a parent or subsidiary thereof, will
automatically be exercised immediately prior to the consummation of the
Corporate Transaction as if such date were the last Purchase Date of the
Offering Period. Any payroll deductions not applied to such purchase shall be
promptly refunded to the participant.

         (b) CORPORATE STRUCTURE. The grant of purchase rights under this Plan
will in no way affect the right of the issuer of Common Stock to adjust,
reclassify, reorganize, or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

<PAGE>

11.      AMENDMENT AND TERMINATION

         (a) AMENDMENT. The Board may from time to time alter, amend, suspend,
or discontinue the Plan with respect to any shares at any time not subject to
purchase rights; PROVIDED that no such action of the Board may, without the
approval of stockholders of the Company, (i) materially increase the benefits
accruing to participants under the Plan, (ii) materially increase the number of
shares which may be issued under the Plan, or which may be issued to one
individual, (iii) materially modify the eligibility requirements under the Plan,
or (iv) make any other change with respect to which the Board determines that
stockholder approval is required by applicable law or regulatory standards.

         (b) TERMINATION. The Board shall have the right, exercisable in its
sole discretion, to terminate the Plan immediately following any Purchase Date.
Should the board elect to exercise such right, then no further purchase rights
shall thereafter be granted or exercised, and no further payroll deductions
shall thereafter be collected under the Plan.

12.      NO EMPLOYMENT OBLIGATION

         Nothing contained in the Plan (or in any purchase right granted
pursuant to the Plan) shall confer upon any employee any right to continue in
the employ of the Company or any Corporate Affiliate or constitute any contract
or agreement of employment or interfere in any was with the right of the Company
or a Corporate Affiliate to reduce such employee's compensation from the rate in
existence at the time of the granting of a purchase right or to terminate such
employee's employment at any time, with or without cause. However, nothing
contained herein or in any purchase right shall affect any contractual rights of
an employee pursuant to a written employment agreement.

13.      USE OF PROCEEDS

         The cash proceeds received by the Company from the issuance of shares
pursuant to purchase rights under the Plan shall be held in a non-interest
bearing trust account.

14.      GOVERNING LAW

         To the extent not otherwise governed by federal law, the Plan and its
implementation shall be governed by and construed in accordance with the laws of
the State of Delaware.
