                  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

         Conductus, Inc. (the "Registrant") hereby incorporates by reference 
into this Registration Statement the following documents previously filed 
with the Securities and Exchange Commission (the "SEC"):

         (a)  The Registrant's report on Form 10-K for the fiscal year ended
              December 27, 1996, and on Form 10-Q for the quarters ended 
              March 28, 1997, June 30, 1997, and September 30, 1997;

         (b)  The Registrant's Registration Statement No. 0-19915 on Form 8-A
              filed with the SEC on March 6, 1992, and amended on July 6, 1993,
              pursuant to Section 12(b) of the Securities Exchange Act of 1934
              (the  "1934 Act"), in which there is described the terms, rights
              and provisions applicable to the Registrant's outstanding Common
              Stock.

         All reports and definitive proxy or information statements filed 
pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date 
of this Registration Statement and prior to the filing of a post-effective 
amendment which indicates that all securities offered hereby have been sold 
or which deregisters all securities then remaining unsold shall be deemed to 
be incorporated by reference into this Registration Statement and to be a 
part hereof from the date of filing of such documents. 

Item 4.  DESCRIPTION OF SECURITIES

         Not Applicable.

Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not Applicable.

Item 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 145 of the Delaware General Corporation Law authorizes a 
court to award or a corporation's Board of Directors to grant indemnification 
to directors and officers in terms sufficiently broad to permit such 
indemnification under certain circumstances for liabilities (including 
reimbursement for expenses incurred) arising under the 1933 Act.  The 
Registrant's Bylaws provide for mandatory indemnification of its directors 
and officers and permissible indemnification of employees and other agents to 
the maximum extent permitted by the Delaware General Corporation Law.  The 
Registrant's Certificate of Incorporation provides that, pursuant to Delaware 
law, its directors shall not be liable for monetary damages for breach of the 
directors' fiduciary duty as directors to the Registrant and its 
stockholders. This provision in the Certificate of Incorporation does not 
eliminate the directors' fiduciary duty, and in appropriate circumstances 
equitable remedies, such as injunctive or other forms of non-monetary relief, 
will remain available under Delaware law.  In addition, each director will 
continue to be subject to liability for breach of the director's duty of 
loyalty to the Registrant for acts or omissions not in good faith or 
involving intentional misconduct, for knowing violations of law, for actions 
leading to improper personal benefit of the director, and for payment of 
dividends or approval of stock repurchases or redemptions that are unlawful 
under Delaware law.

Item 7.  EXEMPTION FROM REGISTRATION CLAIMED

         Not Applicable.

                   Registration Statement.


Item 9.  UNDERTAKINGS

         A.   The undersigned Registrant hereby undertakes:  (1) to file, 
during any period in which offers or sales are being made, a post-effective 
amendment to this Registration Statement (i) to include any prospectus 
required by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the 
prospectus any facts or events arising after the effective date of this 
Registration Statement (or the most recent post-effective amendment thereof) 
which, individually or in the aggregate, represent a fundamental change in 
the information set forth in this Registration Statement and (iii) to include 
any material information with respect to the plan of distribution not 
previously disclosed in this Registration Statement or any material change to 
such information in this Registration Statement; PROVIDED, however, that 
clauses (1)(i) and (1)(ii) shall not apply if the information required to be 
included in a post-effective amendment by those paragraphs is contained in 
periodic reports filed by the Registrant pursuant to Section 13 or Section 
15(d) of the 1934 Act that are incorporated by reference into this 
Registration Statement; (2) that for the purpose of determining any liability 
under the 1933 Act each such post-effective amendment shall be deemed to be a 
new registration statement relating to the securities offered therein and the 
offering of such securities at that time shall be deemed to be the initial 
bona fide offering thereof and (3) to remove from registration by means of a 
post-effective amendment any of the securities being registered which remain 
unsold at the termination of the Registrant's 1992 Stock Option/Stock 
Issuance Plan and 1994 Employee Stock Purchase Plan.

         B.   The undersigned Registrant hereby undertakes that, for purposes 
of determining any liability under the 1933 Act, each filing of the 
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the 
1934 Act that is incorporated by reference into this Registration Statement 
shall be deemed to be a new registration statement relating to the securities 
offered therein, and the offering of such securities at that time shall be 
deemed to be the initial bona fide offering thereof.

         C.   Insofar as indemnification for liabilities arising under the 
1933 Act may be permitted to directors, officers or controlling persons of 
the Registrant pursuant to the indemnification provisions summarized in Item 
6, or otherwise, the Registrant has been advised that, in the opinion of the 
SEC, such indemnification is against public policy as expressed in the 1933 
Act, and is, therefore, unenforceable.  In the event that a claim for 
indemnification against such liabilities (other than the payment by the 
Registrant of expenses incurred or paid by a director, officer or controlling 
person of the Registrant in the successful defense of any action, suit or 
proceeding) is asserted by such director, officer or controlling person in 
connection with the securities being registered, the Registrant will, unless 
in the opinion of its counsel the matter has been settled by controlling 
precedent, submit to a court of appropriate jurisdiction the question whether 
such indemnification by it is against public policy as expressed in the 1933 
Act and will be governed by the final adjudication of such issue.

                                  CONDUCTUS, INC.
                       1992 STOCK OPTION/STOCK ISSUANCE PLAN
                   (AMENDED AND RESTATED EFFECTIVE OCTOBER 1996)
                                          
                                    ARTICLE ONE
                                          
                                      GENERAL
    I.   PURPOSE OF THE PLAN
                                          
         A.   This 1992 Stock Option/Stock Issuance Plan ("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 was restated effective on the first date on which the 
shares of the Corporation's common stock were registered under Section 12(g) 
of the Securities Exchange Act of 1934, as amended (the "1934 Act") (such 
date is hereby designated as the "IPO Effective Date"). 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.

<PAGE>

    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.  Under the Automatic Option Grant Program, 
non-employee Board members automatically receive non-statutory options to 
purchase shares of the Corporation's common stock. The Stock Issuance Program 
shall allow eligible individuals to purchase shares of the Corporation's 
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 ("Committee") of 
two (2) or more non-employee Board members appointed by the Board.  No Board 
member shall be eligible to serve on the Committee if such individual has, 
within the relevant period designated below, received an option grant (other 
than an Automatic Grant) or stock issuance under this Plan or any other stock 
plan of the Corporation (or any parent or subsidiary corporation):

              (1)  for each of the initial members of the Committee, the 
period commencing with the IPO Effective Date and ending with the date of his 
or her appointment to the Committee, or 

              (2)  for any successor or substitute member, the twelve 
(12)-month period immediately preceding the date of his or her appointment to 
the Committee. 

         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 as 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 

                                      2
<PAGE>

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 ("Participant") and/or option grants pursuant to the 
Discretionary Option Grant Program ("Optionee") are as follows:

              (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), and

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

         B.   Members of the Board who are not employees of the Corporation 
or its subsidiaries ("Outside Directors") will receive options in accordance 
with, and only in accordance with, the Plan's Automatic Option Grant Program; 
provided, however, that nothing in this 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 of the Corporation's common stock (the "Common Stock") 
shall be available for issuance under the Plan and shall be drawn from either 
the Corporation's authorized 

                                      3
<PAGE>

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 2,080,000 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 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.

         B.   In no event may any one individual participating in the Plan be 
granted stock options and direct stock issuances for more than 240,000 shares 
of Common Stock in the aggregate over the remaining term of the Plan, subject 
to adjustment from time to time in accordance with the provisions of this 
Section V.  For purposes of such limitation, no stock options or direct stock 
issuances granted prior to January 1, 1994, shall be taken into account.

         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 V 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 in the 
aggregate over the term of the Plan, (iii) the number and/or class of shares 
and price per share in effect under each outstanding option under the Plan 
and (iv) 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.

                                      4

         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 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:

                   -    payment in cash or check payable to the 
      Corporation; or

                   -    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).

                   -    payment through a broker-dealer sale and 
     remittance procedure pursuant to which the Optionee shall 
     provide irrevocable written instructions (i) 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 

                                      6
<PAGE>

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:

              (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.

         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.

                   -    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.

                                      7
<PAGE>

                   -    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.

                   -    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 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.

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

                   -    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 


                                      8
<PAGE>

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.C (and for all other purposes under the Plan):

                   -    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, a non-employee member of the Board or an independent
     consultant or advisor.

                   -    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 
     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: (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.

                                      9
<PAGE>

              (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.

         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 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 


                                      11
<PAGE>

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:

              (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 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.


                                      12
<PAGE>

         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 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 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: 

         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 

                                      13
<PAGE>

     officers and directors of the Corporation subject to the 
     short-swing profit restrictions of Section 16 of the 1934 Act.

          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.A(3) 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 appreciation distribution pursuant to this Section V shall NOT be 
available for subsequent option grants under the Plan.

                                      14

                                 ARTICLE THREE

                           AUTOMATIC OPTION GRANTS

    I.   GRANT OF AUTOMATIC OPTIONS

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

         A.   NO DISCRETION.  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; provided, 
however, that nothing in this Plan shall be construed to prevent an Outside 
Director from declining to receive an Option under this Plan.

         B.   GRANT DATE/NUMBER OF SHARES.  Options shall be granted on the 
dates specified below:

              (1)  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 15,000 shares of Common Stock.

              (2)  INITIAL AUTOMATIC OPTION GRANT.  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 of Directors of the 
Corporation) shall, on the date such person becomes an Outside Director (or, 
if later, the next trading day), automatically receive an option to purchase 
15,000 shares of the Corporation's Common Stock ("Initial Automatic Option 
Grant").

              (3)  ANNUAL AUTOMATIC OPTION GRANT.  Each individual who is 
serving as an Outside Director on October 24, 1996, and has served in that 
capacity for the immediately preceeding ninety (90) days shall automatically 
receive an option to purchase three thousand (3000) shares of Common Stock 
("Annual Automatic Option Grant") on that date.  Thereafter, each Outside 
Director who has served in that capacity for the immediately preceeding 
ninety (90) days and continues to so serve, shall receive as an Annual 
Automatic Option Grant an option to purchase three thousand (3000) shares of 
Common Stock at the Annual Shareholder Meeting , provided the Outside 
Director has not been in the prior employ of the Corporation (or any Parent 
or Subsidiary).

    II.  TERMS AND CONDITIONS

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

                                      15
<PAGE>
         A.   PRICE.  The option price per share will be equal to one hundred 
percent (100%) of the fair market value of one share of Common Stock on the 
date of grant.

         B.   TERM.  The options will have terms of ten (10) years, measured 
from the date of grant, and will be immediately exercisable.  However, any 
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.  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; 
provided, however, that no options may be exercised prior to approval of the 
Plan by the Corporation's stockholders. 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.

         C.   PAYMENT.  Upon exercise of the option, the option price for the 
purchased shares will 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.

         D.   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 vested 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 vested upon the date that 
such services cease.

              (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 to 
the extent that it was vested upon the date that such services cease.  In the 
case of death, the option may be exercised within such period by the estate 
or heirs of the optionee.

                                      16

    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, subsection 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 Section III.C.

         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 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.

                                      17

                                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 ("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 ("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 ("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 

                                      18
<PAGE>

defined in Section I.C(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 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. 

                                      19
<PAGE>

    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 above), 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 above) or at the time of an actual 
Change in Control, to provide for the immediate and automatic vesting 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 

                                      20

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.

                                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) will 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. To the 
extent necessary to comply with Rule 16b-3, the provisions of the Plan 
concerning the eligibility of Outside Directors for awards and the amount, 
price and timing of Automatic Option Grants under this Plan may not be 
amended more than once every six months, other than to comport with changes 
in the Internal Revenue Code or rules thereunder.  In addition, 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 (except for permissible adjustments under Article One, 

                                      22
<PAGE>

Section V.D) or (ii) materially modify the eligibility requirements for 
participation in the Plan or the benefits accruing to Optionees or 
Participants under the Plan.

         B.   (i)  Options to purchase shares of Common Stock may be granted 
under the Plan and (ii) shares of Common Stock may be issued under the Stock 
Issuance Program, which are in both instances 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 Automatic Option Grant Program 
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 
another 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 became effective when adopted by the 
Board and was approved by the stockholders at the 1996 Annual Meeting.  On 
October 24, 1996, the Board adopted amendments to the Plan which (i) 
increased the number of shares of Common Stock issuable thereunder by an 
additional 200,000 shares and (ii) added annual option grants to the 
Automatic Option Grant Program.  The October 1996 amendments became effective 
when adopted and were approved by the stockholders at the 1997 Annual 
Meeting. 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.

                                      23
<PAGE>

         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 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 which dispositions are effected after the IPO 
Effective Date.

         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 on the IPO Effective Date 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 

                                      24
<PAGE>

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, at the IPO Effective Date, 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 of any securities exchange 
on which stock of the same class is then listed. 

    VI.  NO EMPLOYMENT/SERVICE RIGHTS

         Neither the action of the Corporation in establishing the Plan, nor 
any action taken by the Board or the Plan Administrator hereunder, nor any 
provision of the Plan shall be construed so as to grant any individual the 
right to remain in the employ or Service of the Corporation (or any parent or 
subsidiary corporation) for any period of specific duration, and the 
Corporation (or any parent or subsidiary corporation retaining the services 
of such individual) may terminate such individual's employment or Service at 
any time and for any reason, with or without cause.

    VII. WITHHOLDING

         The Corporation's obligation to deliver shares upon the exercise of 
any options granted under Article Two or Article Three or upon the purchase 
of any shares issued under Article Four shall be subject to the satisfaction 
of all applicable Federal, State and local income and employment tax 
withholding requirements.

    VIII. MISCELLANEOUS PROVISIONS

         A.   The right to acquire Common Stock or other assets under the 
Plan may not be assigned, encumbered or otherwise transferred by any optionee 
or Participant.

         B.   The provisions of the Plan shall be governed by the laws of the 
State of California, as such laws are applied to contracts entered into and 
performed in such State.

         C.   The provisions of the Plan shall inure to the benefit of, and 
be binding upon, the Corporation and its successors or assigns, whether by 
Corporate Transaction or otherwise, and the Participants and Optionees, the 
legal representatives of their respective estates, their respective heirs or 
legatees and their permitted assignees.

                                   CONDUCTUS, INC.
                           AUTOMATIC STOCK OPTION AGREEMENT

RECITALS

               A.   The Corporation has implemented an automatic option grant 
program under the Plan pursuant to which eligible non-employee members of the 
Board will automatically receive stock option grants at periodic intervals 
over their period of Board service in order to provide such individuals with 
a meaningful incentive to continue to serve as members of the Board. 

               B.   Optionee is an eligible non-employee Board member, and 
this Agreement is executed pursuant to, and is intended to carry out the 
purposes of, the Plan in connection with the automatic grant of an option to 
purchase shares of Common Stock under the Plan.

               C.   All capitalized terms in this Agreement shall have the 
meanings assigned to them in the attached Appendix.

                    NOW, THEREFORE, it is hereby agreed as follows:

                    1.   GRANT OF OPTION.  The Corporation hereby grants to 
Optionee, as of the Grant Date, a Non-Statutory Option to purchase up to the 
number of Option Shares specified in the Grant Notice.  The Option Shares 
shall be purchasable from time to time during the option term specified in 
Paragraph 2 at the Exercise Price.

                    2.   OPTION TERM.  This option shall have a term of ten 
(10) years measured from the Grant Date and shall accordingly expire at the 
close of business on the Expiration Date, unless sooner terminated in 
accordance with Paragraph 5, 6 or 7.

                    3.   LIMITED TRANSFERABILITY.  This option, together with 
the special stock appreciation right provided under Paragraph 7(b), shall be 
neither transferable nor assignable by Optionee other than by will or by the 
laws of descent and distribution following Optionee's death and may be 
exercised, during Optionee's lifetime, only by Optionee.  However, this 
option may also be assigned in whole or in part during Optionee's lifetime in 
accordance with the terms of a Qualified Domestic Relations Order.  The 
assigned portion shall be exercisable only by the person or persons who 
acquire a proprietary interest in the option pursuant to such Qualified 
Domestic Relations Order.  The terms applicable to the assigned portion shall 
be the same as those in effect for this option immediately prior to such 
assignment and shall be set forth in such documents issued to the assignee as 
the Board may deem appropriate. 

                    4.   EXERCISABILITY/VESTING.

                         (a)  This option shall be immediately exercisable 
for any or all of the Option Shares, whether or not the Option Shares are 
vested in accordance with the Vesting 

<PAGE>

Schedule and shall remain so exercisable until the Expiration Date or sooner 
termination of the option term under Paragraph 5, 6 or 7.

                         (b)  Optionee shall, in accordance with the Vesting 
Schedule, vest in the Option Shares in one or more installments over his or 
her period of Board service.  Vesting in the Option Shares may be accelerated 
pursuant to the provisions of Paragraph 5, 6 or 7.  In no event, however, 
shall any additional Option Shares vest following Optionee's cessation of 
service as a Board member.

                    5.   CESSATION OF BOARD SERVICE.  Should Optionee's 
service as a Board member cease while this option remains outstanding, then 
the option term specified in Paragraph 2 shall terminate (and this option 
shall cease to be outstanding) prior to the Expiration Date in accordance 
with the following provisions: 

                         (a)  Should Optionee cease to serve as a Board 
member for any reason (other than death or Permanent Disability) while 
holding this option, then the period for exercising this option shall be 
reduced to a three (3)-month period (commencing with the date of such 
cessation of Board service), but in no event shall this option be exercisable 
at any time after the Expiration Date. During such limited period of 
exercisability, this option may not be exercised in the aggregate for more 
than the number of Option Shares (if any) in which Optionee is vested on the 
date Optionee ceases service as a Board member.  Upon the EARLIER of (i) the 
expiration of such three (3)-month period or (ii) the specified Expiration 
Date, the option shall terminate and cease to be exercisable with respect to 
any vested Option Shares for which the option has not been exercised.

                         (b)  Should Optionee die during the three (3)-month 
period following his or her cessation of Board service, then the personal 
representative of Optionee's estate or the person or persons to whom the 
option is transferred pursuant to Optionee's will or in accordance with the 
laws of descent and distribution shall have the right to exercise this option 
for any or all of the Option Shares in which Optionee is vested at the time 
of Optionee's cessation of Board service (less any Option Shares purchased by 
Optionee after such cessation of Board service but prior to death).  Such 
right of exercise shall terminate, and this option shall accordingly cease to 
be exercisable for such vested Option Shares, upon the EARLIER of (i) the 
expiration of the three (3)-year period measured from the date of Optionee's 
death or (ii) the specified Expiration Date. 

                         (c)  Should Optionee cease service as a Board member 
by reason of death or Permanent Disability, then Optionee (or the personal 
representative of Optionee's estate or the person or persons to whom the 
option is transferred upon Optionee's death) shall have the right to exercise 
this option for any or all of the Option Shares, to the extent vested on the 
date of cessation of service, at any time prior to the EARLIER of (i) the 
expiration of the twelve (12)-month period measured from the date of 
Optionee's cessation of Board service by reason of Permanent Disability or 
the expiration of the three (3)-year period measured from the date of 
Optionee's death or (ii) the specified Expiration Date. 

                                      2
<PAGE>

                         (d)  Upon Optionee's cessation of Board service for 
any reason, this option shall immediately terminate and cease to be 
outstanding with respect to any and all Option Shares in which Optionee is 
not otherwise at that time vested in accordance with the normal Vesting 
Schedule or the special vesting acceleration provisions of Paragraph 6 or 7 
below.

                         (e)  In the event of a Corporate Transaction or 
Change in Control, the provisions of Paragraph 6 or 7 shall govern the period 
for which this option is to remain exercisable following Optionee's cessation 
of Board service and shall supersede any provisions to the contrary in this 
paragraph.

                    6.   CORPORATE TRANSACTION.

                         (a)  In the event of a Corporate Transaction, all 
Option Shares at the time subject to this option but not otherwise vested 
shall automatically vest so that this option shall, immediately prior to the 
effective date of such Corporate Transaction, become exercisable for any or 
all of the Option Shares as fully-vested shares of Common Stock.  Immediately 
following the Corporate Transaction, this option shall terminate and cease to 
be exercisable except to the extent assumed by the successor corporation (or 
parent thereof) in connection with such Corporate Transaction.

                         (b)  If this option is assumed in connection with a 
Corporate Transaction, then this option shall be appropriately adjusted, 
immediately after such Corporate Transaction, to apply to the number and 
class of securities which would have been issuable to Optionee in 
consummation of such Corporate Transaction had the option been exercised 
immediately prior to such Corporate Transaction, and appropriate adjustments 
shall also be made to the Exercise Price, PROVIDED the aggregate Exercise 
Price shall remain the same.

                         (c)  This Agreement shall not in any 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.

                    7.   CHANGE IN CONTROL/HOSTILE TAKE-OVER.

                         (a)  All Option Shares subject to this option at the 
time of a Change in Control but not otherwise vested shall automatically vest 
so that this option shall, immediately prior to the effective date of such 
Change in Control, become fully exercisable for all of the Option Shares at 
the time subject to this option and may be exercised for all or any portion 
of such shares as fully-vested shares of Common Stock.  This option shall 
remain exercisable for such fully-vested Option Shares until the earliest to 
occur of (i) the Expiration Date, (ii) the sooner termination of this option 
in accordance with Paragraph 5 or 6 or (iii) the surrender of the option in 
connection with a Hostile Take-Over. 

                                      3
<PAGE>

                         (b)  Provided this option has been outstanding for 
at least six (6) months prior to the occurrence of a Hostile Take-Over, 
Optionee shall have the unconditional right (exercisable during the thirty 
(30)-day period immediately following the consummation of such Hostile 
Take-Over) to surrender this option to the Corporation in exchange for a cash 
distribution from the Corporation in an amount equal to the excess of (i) the 
Take-Over Price of the Option Shares at the time subject to the surrendered 
option (whether or not those Option Shares are otherwise at the time vested) 
over (ii) the aggregate Exercise Price payable for such shares.  This 
Paragraph 7(b) limited stock appreciation right shall in all events terminate 
upon the expiration or sooner termination of the option term and may not be 
assigned or transferred by Optionee.

                         (c)  To exercise the Paragraph 7(b) limited stock 
appreciation right, Optionee must, during the applicable thirty (30)-day 
exercise period, provide the Corporation with written notice of the option 
surrender in which there is specified the number of Option Shares as to which 
the Option is being surrendered.  Such notice must be accompanied by the 
return of Optionee's copy of this Agreement, together with any written 
amendments to such Agreement.  The cash distribution shall be paid to 
Optionee within five (5) days following such delivery date, and no approval 
or consent of the Board shall be required in connection with such option 
surrender and cash distribution.  Upon receipt of such cash distribution, 
this option shall be cancelled with respect to the Option Shares subject to 
the surrendered option (or the surrendered portion) and Optionee shall cease 
to have any further right to acquire those Option Shares under this 
Agreement.  The option shall, however, remain outstanding for the balance of 
the Option Shares (if any) in accordance with the terms of this Agreement, 
and the Corporation shall issue a new stock option agreement (substantially 
in the same form as this Agreement) for those remaining Option Shares. 

                    8.   ADJUSTMENT IN OPTION SHARES.  Should any change be 
made to the Common Stock 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 the Corporation's 
receipt of consideration, appropriate adjustments shall be made to (i) the 
total number and/or class of securities subject to this option and (ii) the 
Exercise Price in order to reflect such change and thereby preclude a 
dilution or enlargement of benefits hereunder.

                    9.   STOCKHOLDER RIGHTS.  The holder of this option shall 
not have any stockholder rights with respect to the Option Shares until such 
person shall have exercised the option, paid the Exercise Price and become a 
holder of record of the purchased shares.

                    10.  MANNER OF EXERCISING OPTION.

                         (a)  In order to exercise this option with respect 
to all or any part of the Option Shares for which this option is at the time 
exercisable, Optionee (or any other person or persons exercising the option) 
must take the following actions:

<PAGE>
                              (i)  To the extent the option is 
     exercised for vested Option Shares, execute and deliver to the 
     Corporation a Notice of Exercise for the Option Shares for which 
     the option is exercised. To the extent this option is exercised for 
     unvested Option Shares, execute and deliver to the Corporation a 
     Purchase Agreement. 

                              (ii) Pay the aggregate Exercise Price 
     for the purchased shares in one or more of the following forms:

                                     (A)  cash or check made payable
           to the Corporation, 

                                     (B)  shares of Common Stock held
           by Optionee (or any other person or persons exercising the
           option) for at least six (6) months and valued at Fair
           Market Value on the Exercise Date, or 

                                     (C)  to the extent the option is
           exercised for vested Option Shares, through a special sale
           and remittance procedure pursuant to which Optionee (or any
           other person or persons exercising the option) shall
           concurrently provide irrevocable written instructions (I)
           to a Corporation-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
           Exercise Price payable for the purchased shares plus all
           applicable Federal, state and local income and employment
           taxes required to be withheld by the Corporation by reason
           of such exercise and (II) to the Corporation to deliver the
           certificates for the purchased shares directly to such
           brokerage firm in order to complete the sale. 

                         Except to the extent the sale and remittance
           procedure is utilized in connection with the option
           exercise, payment of the Exercise Price must accompany the
           Notice of Exercise (or the Purchase Agreement) delivered to
           the Corporation in connection with the option exercise.

                               (iii)  Furnish to the Corporation
           appropriate documentation that the person or persons
           exercising the option (if other than Optionee) have the
           right to exercise this option.

                         (b)  As soon after the Exercise Date as practical, 
the Corporation shall issue to or on behalf of Optionee (or any other person 
or persons exercising this option) a certificate for the purchased Option 
Shares, with the appropriate legends affixed thereto.  To the extent any such 
Option Shares are unvested, the certificates for those Option Shares shall be 
endorsed with an appropriate legend evidencing the Corporation's repurchase 
rights and may be held in escrow with the Corporation until such shares vest.

                                      5
<PAGE>

                         (c)  In no event may this option be exercised for 
any fractional shares.

                    11.  COMPLIANCE WITH LAWS AND REGULATIONS.

                         (a)  The exercise of this option and the issuance of 
the Option Shares upon such exercise shall be subject to compliance by the 
Corporation and Optionee with all applicable requirements of law relating 
thereto and with all applicable regulations of any stock exchange (or the 
Nasdaq National Market, if applicable) on which the Common Stock may be 
listed for trading at the time of such exercise and issuance.

                         (b)  The inability of the Corporation to obtain 
approval from any regulatory body having authority deemed by the Corporation 
to be necessary to the lawful issuance and sale of any Common Stock pursuant 
to this option shall relieve the Corporation of any liability with respect to 
the non-issuance or sale of the Common Stock as to which such approval shall 
not have been obtained. The Corporation, however, shall use its best efforts 
to obtain all such approvals.

                    12.  SUCCESSORS AND ASSIGNS.  Except to the extent 
otherwise provided in Paragraph 3 or 6, the provisions of this Agreement 
shall inure to the benefit of, and be binding upon, the Corporation and its 
successors and assigns and Optionee, Optionee's assigns and the legal 
representatives, heirs and legatees of Optionee's estate.

                    13.  NOTICES.  Any notice required to be given or 
delivered to the Corporation under the terms of this Agreement shall be in 
writing and addressed to the Corporation at its principal corporate offices.  
Any notice required to be given or delivered to Optionee shall be in writing 
and addressed to Optionee at the address indicated below Optionee's signature 
line on the Grant Notice. All notices shall be deemed effective upon personal 
delivery or upon deposit in the U.S. mail, postage prepaid and properly 
addressed to the party to be notified. 

                    14.  CONSTRUCTION.  This Agreement and the option 
evidenced hereby are made and granted pursuant to the Plan and are in all 
respects limited by and subject to the terms of the Plan.  

                    15.  GOVERNING LAW.  The interpretation, performance and 
enforcement of this Agreement shall be governed by the laws of the State of 
California without resort to that State's conflict-of-laws rules.

                                STOCK OPTION AGREEMENT
                                           
                                      WITNESSETH
                                           
RECITALS

     A.   On January 23, 1995, Conductus, Inc. (the "Corporation") established
an Automatic Option Grant Program under its 1992 Stock Option/Stock Issuance
Plan for the purpose of attracting and retaining qualified directors and provide
equity incentives that align thier interests with those of the stockholders.

     B.   Under the Automatic Option Grant Program, non-employee Directors of
the Corporation ("Outside Directors") receive an initial grant of an option to
purchase 15,000 shares of common stock of the Corporation ("Common Stock") at
100% of the fair market value of the stock on the date they first become a
Director, plus annual grants of 3,000 shares of Commomn Stock.

     C.   Optionee joined the Board on July 1, 1996 and received an option for
15,000 shares of Common Stock with an exercise price of $11.25 per share.

     D.   Outside Directors who received an option grant on January 23, 1995,
when the Automatic Option Grant Program was established, have an the option
exercise price was $4.9375.  The highest exercise price for initial options
under the Automatic Option Grant Program, other than Optionee's, through October
24, 1997 was $6.563.

     E.   Optionee's initial Option Grant lacks parity with those of other
Outside Directors who joined the Board either before or after Optionee.

     F.   The Board of Directors, Optionee abstaining, has, therefore approved
the option as a replacement for the Automatic Option Grant previously awarded
Optionee.


          NOW, THEREFORE, it is hereby agreed as follows:

          1.   SURRENDER OF OPTION  Concurrently with the acceptance of this
Stock Option agreement, Optionee surrenders all rights under Stock Option Grant
N0340 dated July 1, 1996.

          2.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, a Non-Statutory Option to purchase up to the number of Option
Shares specified in the Grant Notice.  The Option Shares shall be purchasable
from time to time during the option term specified in Paragraph 2 at the

          3.   OPTION TERM.  This option shall have a term of ten (10) years
measured from the Vesting Commencement Date and shall accordingly expire at the
close of business on the Expiration Date, unless sooner terminated in accordance
with Paragraph 5, 6 or 7.

          4.   LIMITED TRANSFERABILITY.  This option, together with the special
stock appreciation right provided under Paragraph 7(b), shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.  However, this option may also be
assigned in whole or in part during Optionee's lifetime in accordance with the
terms of a Qualified Domestic Relations Order.  The assigned portion shall be
exercisable only by the person or persons who acquire a proprietary interest in
the option pursuant to such Qualified Domestic Relations Order.  The terms
applicable to the assigned portion shall be the same as those in effect for this
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Board may deem appropriate. 

          5.   EXERCISABILITY/VESTING.

               (a)  This option shall be immediately exercisable for any or all
of the Option Shares, whether or not the Option Shares are vested in accordance
with the Vesting Schedule and shall remain so exercisable until the Expiration
Date or sooner termination of the option term under Paragraph 5, 6 or 7.

               (b)  Optionee shall, in accordance with the Vesting Schedule,
vest in the Option Shares in one or more installments over his or her period of
Board service.  Vesting in the Option Shares may be accelerated pursuant to the
provisions of Paragraph 5, 6 or 7.  In no event, however, shall any additional
Option Shares vest following Optionee's cessation of service as a Board member.

          6.   CESSATION OF BOARD SERVICE.  Should Optionee's service as a Board
member cease while this option remains outstanding, then the option term
specified in Paragraph 2 shall terminate (and this option shall cease to be
outstanding) prior to the Expiration Date in accordance with the following
provisions: 

               (a)  Should Optionee cease to serve as a Board member for any
reason (other than death or Permanent Disability) while holding this option,
then the period for exercising this option shall be reduced to a three (3)-month
period (commencing with the date of such cessation of Board service), but in no
event shall this option be exercisable at any time after the Expiration Date. 
During such limited period of exercisability, this option may not be exercised
in the aggregate for more than the number of Option Shares (if any) in which
Optionee is vested on the date Optionee ceases service as a Board member.  Upon
the EARLIER of (i) the expiration of such three (3)-month period or (ii) the
specified Expiration Date, the option shall terminate and cease to be
exercisable with respect to any vested Option Shares for which the option has
not been exercised.

                                      5
<PAGE>

               (b)  Should Optionee die during the three (3)-month period
following his or her cessation of Board service, then the personal
representative of Optionee's estate or the person or persons to whom the option
is transferred pursuant to Optionee's will or in accordance with the laws of
descent and distribution shall have the right to exercise this option for any or
all of the Option Shares in which Optionee is vested at the time of Optionee's
cessation of Board service (less any Option Shares purchased by Optionee after
such cessation of Board service but prior to death).  Such right of exercise
shall terminate, and this option shall accordingly cease to be exercisable for
such vested Option Shares, upon the EARLIER of (i) the expiration of the three
(3)-year period measured from the date of Optionee's death or (ii) the specified
Expiration Date. 

               (c)  Should Optionee cease service as a Board member by reason of
death or Permanent Disability, then Optionee (or the personal representative of
Optionee's estate or the person or persons to whom the option is transferred
upon Optionee's death) shall have the right to exercise this option for any or
all of the Option Shares, to the extent vested on the date of cessation of
service, at any time prior to the EARLIER of (i) the expiration of the twelve
(12)-month period measured from the date of Optionee's cessation of Board
service by reason of Permanent Disability or the expiration of the three 
(3)-year period measured from the date of Optionee's death or (ii) the 
specified Expiration Date. 

               (d)  Upon Optionee's cessation of Board service for any reason,
this option shall immediately terminate and cease to be outstanding with respect
to any and all Option Shares in which Optionee is not otherwise at that time
vested in accordance with the normal Vesting Schedule or the special vesting
acceleration provisions of Paragraph 6 or 7 below.

               (e)  In the event of a Corporate Transaction or Change in
Control, the provisions of Paragraph 6 or 7 shall govern the period for which
this option is to remain exercisable following Optionee's cessation of Board
service and shall supersede any provisions to the contrary in this paragraph.

          7.   CORPORATE TRANSACTION.

               (a)  In the event of a Corporate Transaction, all Option Shares
at the time subject to this option but not otherwise vested shall automatically
vest so that this option shall, immediately prior to the effective date of such
Corporate Transaction, become exercisable for any or all of the Option Shares as
fully-vested shares of Common Stock.  Immediately following the Corporate
Transaction, this option shall terminate and cease to be exercisable except to
the extent assumed by the successor corporation (or parent thereof) in
connection with such Corporate Transaction.

               (b)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised 

                                      6
<PAGE>

immediately prior to such Corporate Transaction, and appropriate adjustments 
shall also be made to the Exercise Price, PROVIDED the aggregate Exercise 
Price shall remain the same.

               (c)  This Agreement shall not in any 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.

          8.   CHANGE IN CONTROL/HOSTILE TAKE-OVER.

               (a)  All Option Shares subject to this option at the time of a
Change in Control but not otherwise vested shall automatically vest so that this
option shall, immediately prior to the effective date of such Change in Control,
become fully exercisable for all of the Option Shares at the time subject to 
this option and may be exercised for all or any portion of such shares as 
fully-vested shares of Common Stock.  This option shall remain exercisable 
for such fully-vested Option Shares until the earliest to occur of (i) the 
Expiration Date, (ii) the sooner termination of this option in accordance 
with Paragraph 5 or 6 or (iii) the surrender of the option in connection with 
a Hostile Take-Over. 

               (b)  Provided this option has been outstanding for at least six
(6) months prior to the occurrence of a Hostile Take-Over, Optionee shall have
the unconditional right (exercisable during the thirty (30)-day period
immediately following the consummation of such Hostile Take-Over) to surrender
this option to the Corporation in exchange for a cash distribution from the
Corporation in an amount equal to the excess of (i) the Take-Over Price of the
Option Shares at the time subject to the surrendered option (whether or not
those Option Shares are otherwise at the time vested) over (ii) the aggregate
Exercise Price payable for such shares.  This Paragraph 7(b) limited stock
appreciation right shall in all events terminate upon the expiration or sooner
termination of the option term and may not be assigned or transferred by
Optionee.

               (c)  To exercise the Paragraph 7(b) limited stock appreciation
right, Optionee must, during the applicable thirty (30)-day exercise period,
provide the Corporation with written notice of the option surrender in which
there is specified the number of Option Shares as to which the Option is being
surrendered.  Such notice must be accompanied by the return of Optionee's copy
of this Agreement, together with any written amendments to such Agreement.  The
cash distribution shall be paid to Optionee within five (5) days following such
delivery date, and no approval or consent of the Board shall be required in
connection with such option surrender and cash distribution.  Upon receipt of
such cash distribution, this option shall be cancelled with respect to the
Option Shares subject to the surrendered option (or the surrendered portion) and
Optionee shall cease to have any further right to acquire those Option Shares
under this Agreement.  The option shall, however, remain outstanding for the
balance of the Option Shares (if any) in accordance with the terms of this
Agreement, and the Corporation shall issue a new stock option agreement
(substantially in the same form as this Agreement) for those remaining Option
Shares. 

                                      7
<PAGE>

          9.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the 
Common Stock 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 the Corporation's receipt of 
consideration, appropriate adjustments shall be made to (i) the total number 
and/or class of securities subject to this option and (ii) the Exercise Price 
in order to reflect such change and thereby preclude a dilution or 
enlargement of benefits hereunder.

          10.  STOCKHOLDER RIGHTS.  The holder of this option shall not have any
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

          11.  MANNER OF EXERCISING OPTION.

               (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                    i)   To the extent the option is exercised for 
vested Option Shares, execute and deliver to the Corporation a 
Notice of Exercise for the Option Shares for which the option is 
exercised.  To the extent this option is exercised for unvested 
Option Shares, execute and deliver to the Corporation a Purchase 
Agreement. 

                    ii)  Pay the aggregate Exercise Price for the 
purchased shares in one or more of the following forms:

                         (1)  cash or check made payable to the 
Corporation, 

                         (2)  shares of Common Stock held by 
Optionee (or any other person or persons exercising the option) for 
at least six (6) months and valued at Fair Market Value on the 
Exercise Date, or 

                         (3)  to the extent the option is exercised 
for vested Option Shares, through a special sale and remittance 
procedure pursuant to which Optionee (or any other person or 
persons exercising the option) shall concurrently provide 
irrevocable written instructions (I) to a Corporation-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 
Exercise Price payable for the purchased shares plus all applicable 
Federal, state and local income and employment taxes required to be 
withheld by the Corporation by reason of such exercise and (II) to 
the Corporation to deliver the certificates for the purchased 
shares directly to such brokerage firm in order to complete the 
sale. 

     EXCEPT TO THE EXTENT THE SALE AND REMITTANCE PROCEDURE IS 
UTILIZED IN CONNECTION WITH THE OPTION EXERCISE, PAYMENT OF THE 
EXERCISE PRICE MUST 

                                      8
<PAGE>

ACCOMPANY THE NOTICE OF EXERCISE (OR THE PURCHASE AGREEMENT) 
DELIVERED TO THE CORPORATION IN CONNECTION WITH THE OPTION 
EXERCISE. 

                    iii) Furnish to the Corporation appropriate 
documentation that the person or persons exercising the option (if 
other than Optionee) have the right to exercise this option.

               (b)  As soon after the Exercise Date as practical, the 
Corporation shall issue to or on behalf of Optionee (or any other person or 
persons exercising this option) a certificate for the purchased Option 
Shares, with the appropriate legends affixed thereto.  To the extent any such 
Option Shares are unvested, the certificates for those Option Shares shall be 
endorsed with an appropriate legend evidencing the Corporation's repurchase 
rights and may be held in escrow with the Corporation until such shares vest.

               (c)  In no event may this option be exercised for any 
fractional shares.

          12.  COMPLIANCE WITH LAWS AND REGULATIONS.  

               (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

               (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been 
obtained. The Corporation, however, shall use its best efforts to obtain all 
such approvals.

          13.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraph 3 or 6, the provisions of this Agreement shall inure to the benefit
of, and be binding upon, the Corporation and its successors and assigns and
Optionee, Optionee's assigns and the legal representatives, heirs and legatees
of Optionee's estate.

          14.  NOTICES.  Any notice required to be given or delivered to the
Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices.  Any notice required to
be given or delivered to Optionee shall be in writing and addressed to Optionee
at the address indicated below Optionee's signature line on the Grant Notice. 
All notices shall be deemed effective upon personal delivery or upon deposit in
the U.S. mail, postage prepaid and properly addressed to the party to be
notified.

          15.  CONSTRUCTION.  This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan.  

          16.  GOVERNING LAW.  The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of California
without resort to that State's conflict-of-laws rules.

THIS DOCUMENT CONSTITUTES PART OF THE OFFICIAL PROSPECTUS COVERING SECURITIES 
THAT HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.

          Conductus, Inc. (the "Corporation") is offering shares of its common
stock to you pursuant to a stock option (the "Option") granted by the
disinterested members of the Board of Directors of the Corporation in exchange
for your surrender of rights under that Automatic Option Grant dated July 1,
1996.  Federal securities laws require that corporations making public stock
offerings under registration statements filed with the Securities and Exchange
Commission provide a copy of a prospectus to all prospective purchasers.  The
prospectus is designed to enable a prospective investor to make an informed
decision as to the merits of an investment in the Corporation.

          This Summary and Prospectus is a description of the principal terms
and conditions of the Option.

                         INFORMATION REGARDING THE OPTION

     1.   GENERAL INFORMATION

          The Option was granted to you on November __, 1997 in consideration
for your surrender of the Initial Automatic Option Grant dated July 1, 1996. 
The Option grants you the right to purchase shares of the Corporation's common
stock (the "Common Stock") at a specified exercise price.  The terms and
conditions of the Option are set forth in the written Notice of Grant of Stock
Option and Stock Option Agreement evidencing the Option.

          The Option is NOT subject to the provisions of the Employee Retirement
Income Security Act of 1974 (ERISA) or Section 401(a) of the Internal Revenue
Code.

     2.   SECURITIES TO BE OFFERED

          You can purchase up to 15,000 shares of Common Stock under the 
Option. The Common Stock will be made available either from authorized but 
unissued shares of Common Stock, or from shares of Common Stock reacquired by 
the Corporation, including shares repurchased on the open market.

          In the event there should be any change in the outstanding Common
Stock by reason of a stock dividend, stock split, recapitalization, combination
of shares or other change affecting the outstanding Common Stock as a class
without receipt of consideration, appropriate adjustments will automatically be
made to the number and/or class of shares and the exercise price per share in
effect under the Option in order to preclude the dilution or enlargement of
benefits thereunder.

     3.   TERM; VESTING


<PAGE>

          The Option has a term of ten (10) years from the vesting commencement
date and will terminate on July 1, 2006.  Your Option is immediately
exercisable, subject to a repurchase right that expires on the schedule set
forth in the Notice of Grant.  The Option will continue to vest only so long as
you continue as a member of the Board of Directors of the Corporation.  However,
the vesting of the option shares under the Option grant will be subject to
acceleration upon an acquisition or other change in control of the Corporation. 
See the section below titled "Early Termination of Option."

     4.   EXERCISE OF OPTION

          To exercise your Option, you must deliver an executed Notice of
Exercise to the Stock Administrator at the Corporation's principal offices in
Sunnyvale, California.  The notice must specify the number of shares to be
purchased under the option and must be accompanied by appropriate proof that the
person exercising the option, if other than you, has the right to effect the
exercise.  The extent that you exercise the Option for unvested shares, you must
also deliver a signed stock purchase agreement (in form and substance
satisfactory to the Corporation) which evidences the Corporation's right to
repurchase those unvested shares, at the exercise price paid per share, upon
your cessation of Board service prior to vesting in those shares and which
precludes the sale or other transfer of those shares while they remain subject
to such repurchase right.

     5.   EXERCISE PRICE AND PAYMENT

          The exercise price is $6.50 per share of Common Stock.  The exercise
price for the number of shares you wish to purchase must be paid at the time you
exercise the Option.  You may pay (i) in cash or check payable to the
Corporation or (ii) by delivery of shares of Common Stock.  Any shares delivered
in payment of the exercise price must have been held for at least six (6) months
and will be valued at fair market value (see section below titled "Valuation")
on the exercise date.  You will be required to satisfy all applicable income and
employment tax withholding requirements at that time.  For information about the
tax treatment applicable to your Option exercise, see the "Questions and Answers
on Federal Tax Consequences" section below.

     6.   EARLY TERMINATION OF OPTION

          Following your cessation of Board Service you may exercise your
outstanding Option for any or all shares for which the Option is vested on your
termination date.  You will have three (3) months following such termination in
which to effect this exercise.  However, you must in all events exercise your
Option before July 1, 2006.  Upon expiration of the three (3)-month period or
(if earlier) upon the expiration date of the Option, the Option will  terminate
and cease to remain outstanding for all vested shares for which the option has
not otherwise been exercised.  In addition, if your cessation of Service is due
to misconduct, your Option will terminate immediately. 

                                      4
<PAGE>
          If you die while your Option is outstanding, the personal
representative of your estate or the person or persons to whom the Option is
transferred by the provisions of your will or the laws of inheritance following
your death may exercise your Option for any or all of the shares for which the
Option was vested on the date your Service terminated.  The Option must be
exercised by the EARLIER of (i) the expiration of the third anniversary of your
death or (ii) the expiration date of the Option term.

          If you become permanently disabled and cease by reason thereof to
remain in the Service of the Corporation, you will have a period of twelve (12)
months from the date of such cessation of Service during which to exercise your
Option for any or all of the shares for which the Option was vested on the date
your Service terminated.  In no event, however, may you exercise the Option
after the specified expiration date of the Option term.  For purposes of the
Option, you will be deemed to be permanently disabled if you are unable to
engage in any substantial gainful activity by reason of any medically
determinable physical or mental impairment expected to result in death or to be
of continuous duration of twelve (12) consecutive months or more.  

     7.   CORPORATE TRANSACTION

          Upon the consummation of a Corporate Transaction, the Option will
automatically become fully vested, then terminate and cease to be outstanding,
unless it is assumed by the successor or corporation or its parent.

          A Corporate Transaction is defined under the Option as:

          -    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 in which the Corporation is incorporated,

          -    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

          -    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.

          If the Option is assumed, the Option will, immediately after the
Corporate Transaction, be appropriately adjusted to apply and pertain to the
number and class of securities which would have been issuable in completion of
the Corporate Transaction, to an actual holder of the same number of shares of
Common Stock as are subject to the Option immediately prior to the Corporate
Transaction.  Appropriate adjustments will also be made to the exercise price
payable per share, PROVIDED the aggregate exercise price will remain the same.

     8.   CHANGE IN CONTROL OF THE COMPANY

                                      5
<PAGE>

          In the event of a Change in Control, the Option will automatically
accelerate so that it will, immediately prior to the specified effective date of
the Corporate Transaction, become fully exercisable for the total number of
shares of Common Stock at the time subject to the Option and may be exercised
for all or any portion of such shares.

          Each option accelerated in connection with such a Change in Control
will remain fully exercisable until such option expires or terminates.

     9.   HOSTILE TAKEOVER

          Upon the occurrence of a Hostile Take-Over (as defined below), you
will have a thirty (30) day period immediately following such Hostile Take-Over
in which to surrender the Option, provided you have held the Option for at least
six (6) months from the vesting date, in return for a cash distribution from the
Company.  The distribution will be in an amount per share of Common Stock
subject to the cancelled option (whether or not the optionee is otherwise at the
time vested in those shares) equal to the Take-Over Price per share less the
option exercise price payable per share.  The Take-Over Price per share will be
deemed to be equal to the greater of (a) the fair market value per share of
Common Stock on the option surrender date, or (b) the highest reported price per
share of Common Stock paid in effecting such Hostile Take-Over.  The cash
distribution payable upon such option surrender will be made to you within five
(5) days following the option surrender date.

          A Hostile Take-Over will be deemed to occur in the event of:

          (i)  the acquisition, directly or indirectly, by any person or related
group of persons (other than the Company or a person that directly or indirectly
controls, is controlled by, or is under common control with, the Company) of
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 Company's outstanding securities pursuant to a tender or exchange
offer made directly to the Company's stockholders which the Board does not
recommend such stockholders to accept, AND

          (2)  more than fifty percent (50%) of the securities so acquired are
accepted from persons other than the officers and directors of the Company
subject to the short-swing profit restrictions of Section 16 of the 1934 Act.

          The shares of Common Stock subject to each option surrendered in
connection with the Hostile Take-Over will not be available for subsequent
issuance under the Stock Plan.

     10.  TRANSFER RESTRICTION

          Your Option cannot be assigned or transferred, except by the
provisions of your will or the laws of inheritance following your death.

                                      6
<PAGE>

     11.  STOCKHOLDER RIGHTS

          You will not have the rights of a stockholder with respect to the
shares covered by the Option until you exercise the Option and pay the exercise
price.

     12.  DISPOSITION OF OPTION SHARES

          As a member of the Board, you are subject to the short-swing profit
restrictions of the Federal securities laws.  Section 16(b) of the 1934 Act
requires the Corporation to recover any profit realized by certain officers and
any director or beneficial owner of ten percent (10%) or more of the outstanding
Common Stock (a "Section 16 Insider") from any purchase and sale, or sale and
purchase, of such Common Stock made within a period of less than six (6) months.

          The Securities and Exchange Commission (the "SEC") has issued a series
of rules which govern the short-swing liability treatment of certain
transactions effected by a Section 16 Insider with respect to stock options. 
The application of these rules to various Option transactions may be summarized
as follows:

          GRANT OF OPTION.  The receipt of an option grant will be an exempt
transaction and will not be treated as a "purchase" of the underlying option
shares for short-swing liability purposes, if the grant has "Section 16
Approval."  This means that the grant is approved by:

          (i)  the Board,

          (ii) the Plan Administrator, OR 

          (iii)     the stockholders.

          If the option grant has not received Section 16 Approval, the grant is
still exempt if the shares acquired under the option are not sold until at least
six (6) months after the grant of the option.  Should this six-month requirement
not be satisfied, then the option grant will be treated as a "purchase" of the
option shares retroactive to the grant date.  Such purchase will be matched, for
short-swing liability purposes, with any sales of Common Stock made within six
(6) months before or after the grant date of the option.

          OPTION EXERCISE BY PAYING CASH OR THROUGH SAME-DAY SALE.  The exercise
of an option will be an exempt transaction and will not be treated as a
"purchase" of the acquired shares for short-swing liability purposes, if the
original option grant received Section 16 Approval.  If the Section 16 Approval
requirements have not been met, then the exercise of an option is still an
exempt transaction, UNLESS the market price of the Common Stock at the time the
option is exercised is lower than the exercise price paid for the shares.

          OPTION EXERCISE BY DELIVERY OF SHARES.  The delivery of Common Stock
in payment of the exercise price and the exercise of the option will be an
exempt transaction for short-swing liability purposes if the original option
grant (including the feature permitting the delivery of shares) or the exercise
received Section 16 Approval.

                                      7
<PAGE>

          OPTION EXERCISE BY STOCK WITHHOLDING.  The exercise of an option and
payment of the exercise price and/or applicable withholding taxes by the
withholding of a portion of the Common Stock otherwise issuable to the Section
16 Insider by the Company is exempt if the original option grant (including the
stock withholding feature) or the exercise received Section 16 Approval.

          AWARD OF COMMON STOCK.  The award of Common Stock by the Company for
services rendered to the Company, a Parent or Subsidiary is exempt if such award
received Section 16 Approval or the shares of Common Stock acquired were held
for at least six  (6) months prior to their disposition.

          FORFEITURE OF UNVESTED SHARES.  The surrender of unvested shares of
Common Stock to the Company for cancellation or expiration without any cash
payment or other consideration to the participant will not be deemed a "sale" of
those shares for short-swing liability purposes, if the original grant received
Section 16 Approval.  

          SALE OF SHARES.  The sale of Common Stock acquired by a Section 16
Insider under the Plan will be treated as a "sale" transaction for short-swing
liability purposes and will be matched with any non-exempt purchases of Common
Stock (e.g., open-market purchases) made by the Section 16 Insider within six
(6) months before or after the date of such sale.

     13.  REPORTING REQUIREMENTS

          Each of the following Plan transactions involving a Section 16 Insider
must be reported on the annual Form 5 required to be filed by such individual
within 45 days after the close of the Company's fiscal year in which such
transaction occurs and may be reported on any earlier-filed Form 4:

          *    Receipt of option grant
          *    Receipt of stock award
          *    Forfeiture of restricted stock

          The following transactions must be reported on a Form 4 filed within
ten days after the close of the calendar month in which the transaction is
effected:  

          *    Exercise of option (1)
          *    Withholding or delivery of shares to satisfy tax withholding
               obligations
          *    Sale of shares

          The surrender of options for cancellation or the expiration of options
for no consideration does not have to be reported.

     14.  WHAT RESTRICTIONS APPLY IF I AM AN AFFILIATE?

- -----------------
(1)     If an option grant has not been reported, such grant must be reported 
on the same Form 4 on which the option exercise is reported.

                                      8
<PAGE>

          In general, executive officers and other persons with power to manage
and direct the policies of the Company, relatives of these persons and trusts,
estates, corporations or other entities controlled by any of these persons or
their relatives may be deemed to be affiliates of the Company.  Affiliates of
the Company are obligated to resell their Common Stock in compliance with SEC
Rule 144.  This rule requires such sales to be effected in "broker's
transactions," as defined in the rule, and a written notice of each sale must be
filed with the SEC at the time of such sale.  The rule also limits the number of
shares which may be sold in any three (3)-month period to the greater of (a) one
percent (1%) of the outstanding Common Stock or (b) the average weekly reported
volume of trading in such shares on all securities exchanges during the four (4)
calendar weeks preceding the filing of the required notice of proposed sale. 
However, the holding period requirement of Rule 144 will not be applicable to
any Common Stock acquired under the Plan.

          SALE OF SHARES.  The sale of shares acquired by you upon exercise of
the Option will be treated as a sale for short-swing liability purposes and will
be matchable against any non-exempt purchases of Common Stock (e.g., open-market
purchases) made by you within six (6) months before or after the sale date.  

          REPORTING REQUIREMENTS.  The exercise of the Option must be reported
on the next Form 4 or 5 otherwise required of you as a Section 16 Insider, but
may be reported on any earlier-filed Form 4.  The delivery of shares in payment
of the Option price must be reported on the annual For 5 and may be reported on
any earlier-filed Form 4.  The sale of Common Stock must be reported on a Form 4
filed within ten (10) days after the close of the calendar month in which the
sale is effected.  

          ACCORDINGLY, YOU SHOULD CONSULT WITH COUNSEL BEFORE OFFERING FOR SALE
ANY SHARES OF COMMON STOCK ACQUIRED UNDER THE OPTION IN ORDER TO ASSURE YOUR
COMPLIANCE WITH RULE 144, SECTION 16 AND ALL OTHER APPLICABLE PROVISIONS OF
FEDERAL AND STATE SECURITIES LAWS.

              QUESTIONS AND ANSWERS ON FEDERAL TAX CONSEQUENCES

          The following is a general description of the Federal income tax
consequences of the Option.  State and local tax treatment, which is not
discussed below, may vary from such Federal income tax treatment.  You should
consult with your own tax advisor as to the tax consequences of the grant and
exercise of the Option.  

          T1.  DID THE GRANT OF MY OPTION RESULT IN FEDERAL INCOME TAX LIABILITY
               TO ME?

          No.
          
          T2.  WILL THE EXERCISE OF A NON-STATUTORY OPTION RESULT IN FEDERAL
               INCOME TAX LIABILITY TO ME?

                                      9
<PAGE>

          Normally, you will recognize ordinary income in the year in which the
Non-Statutory Option is exercised in an amount equal to the excess of (a) the
fair market value of the purchased shares on the exercise date over (b) the
exercise price paid for those shares.  This income will be reported by the
Company on your W-2 wage statement for the year of exercise, and you will be
required to satisfy the tax withholding requirements applicable to this income
if you are an employee or former employee.

          T3.  WHAT IF THE SHARES PURCHASED UNDER A NON-STATUTORY OPTION ARE
               SUBJECT TO A SUBSTANTIAL RISK OF FORFEITURE, SUCH AS THE
               COMPANY'S REPURCHASE RIGHTS?

          If the shares you purchase under a Non-Statutory Option are subject to
a substantial risk of forfeiture, such as the Company's right to repurchase
those shares at the original exercise price upon your termination of service
prior to vesting in those shares, then you will not recognize any taxable income
at the time of exercise but will have to report as ordinary income, as and when
the Company's repurchase rights lapse, an amount equal to the excess of (a) the
fair market value of the shares on the date they vest over (b) the exercise
price paid for the shares.  In addition, the holding period for determining
whether any additional gain (upon a subsequent disposition of the shares) is a
long-term, mid-term or short-term capital gain will not commence until the
repurchase rights start to lapse.

          If you purchase shares subject to a substantial risk of forfeiture,
you may elect under Code Section 83(b) to recognize income at the time of
exercise (see Question T4).  If such an election is made, you will not recognize
any additional income with respect to your shares until the shares are sold or
otherwise transferred in a taxable transaction.

          T4.  WHAT IS THE EFFECT OF MAKING A SECTION 83(b) ELECTION?

          If you purchase shares subject to the Company's repurchase right or
other substantial risk of forfeiture, you may elect under Code Section 83(b) to
include as ordinary income in the year of exercise an amount equal to the excess
of (a) the fair market value of the purchased shares on the exercise date over
(b) the exercise price paid for the shares.  The fair market value of the
purchased shares will be determined as if the shares were not subject to the
Company's repurchase right or other risk of forfeiture.  If you make a Section
83(b) election, you will not recognize any additional income when the Company's
repurchase right or other forfeiture risk subsequently lapses.

          The Section 83(b) election must be filed with the Internal Revenue
Service within 30 days following the date the option is exercised.  Any ordinary
income resulting from the election will be subject to applicable tax withholding
requirements if you are an employee or former employee.  The election generally
is not revocable and cannot be made after the 30-day period has expired.

          T5.  WILL I RECOGNIZE ADDITIONAL INCOME WHEN I SELL SHARES ACQUIRED
               UNDER A NON-STATUTORY OPTION?

                                      10
<PAGE>

          Yes.  You will recognize a capital gain to the extent the amount
realized upon the sale of such shares exceeds their fair market value at the
time of exercise.  The capital gain will be long-term if you held the shares
more than 18 months, mid-term if you held the shares more than one year but not
more than 18 months, and short-term if you held the shares not more than one
year.  A capital loss will result to the extent the amount realized upon the
sale is less than such fair market value.  The holding period normally starts at
the time the Non-Statutory Option is exercised. 

          T6.  WHAT ARE THE CONSEQUENCES OF PAYING THE EXERCISE PRICE OF A 
               NON-STATUTORY OPTION IN THE FORM OF COMMON STOCK PREVIOUSLY
               ACQUIRED UPON THE EXERCISE OF OPTIONS OR THROUGH OPEN-MARKET
               PURCHASES?

          You will not recognize any taxable income to the extent the Common
Stock received upon the exercise of the Non-Statutory Option equals in number
the shares of Common Stock delivered in payment of the exercise price.  For
Federal income tax purposes, these newly acquired shares will have the same
basis and capital gain holding period as the delivered shares.

          The additional shares of Common Stock received upon the exercise of
the Non-Statutory Option will, in general, have to be reported as ordinary
income for the year of exercise in an amount equal to their fair market value on
the exercise date.  These additional shares will have a tax basis equal to such
fair market value and a capital gain holding period measured (in general) from
the exercise date. 

          T7.  WHAT ARE THE FEDERAL TAX CONSEQUENCES TO THE COMPANY?

          The Company will be entitled to an income tax deduction equal to the
amount of ordinary income you recognize in connection with the exercise of a
Non-Statutory Option.  The deduction will, in general, be allowed for the
taxable year of the Company in which you recognize such ordinary income.

                               RESTRICTED SHARE

          T1.  WILL A RESTRICTED SHARE AWARD OR PURCHASE RESULT IN FEDERAL
               INCOME TAX LIABILITY TO ME?

          Restricted shares are shares that are subject to a vesting schedule
(or some other substantial risk of forfeiture).  If you separate from service
before vesting in your shares, the shares are forfeited and revert to the
Company.  If you paid for the shares, the purchase price will be refunded. 
Generally, you will not recognize taxable income at the time of an award or
purchase of restricted shares.  However, you may make an election under Code
Section 83(b) to be taxed at the time of the award (see Question T22).

          T2.  WILL THE VESTING OF SHARES UNDER A RESTRICTED SHARE AWARD RESULT
               IN FEDERAL INCOME TAX LIABILITY TO ME?

                                      11
<PAGE>

          If you did not elect under Code Section 83(b) to recognize income at
the time of the award or purchase, you will recognize taxable income at the time
of vesting.  The taxable income will be equal to the excess of the fair market
value of the restricted shares at the time the shares VEST over the amount (if
any) you paid for the restricted shares.

          T3.  WHAT IS THE EFFECT OF MAKING A SECTION 83(b) ELECTION?

          If you receive or purchase shares that remain subject to vesting, you
may elect under Code Section 83(b) to include as ordinary income in the year of
the award or purchase an amount equal to the excess of (a) the fair market value
of the shares on the transfer date over (b) the purchase price (if any) paid for
the shares.  The fair market value of the purchased shares will be determined as
if the shares were not subject to forfeiture.  If you make the Section 83(b)
election, you will not recognize any additional income when the shares vest. 
Any appreciation in the value of the restricted shares after the award or
purchase is not taxed as compensation, but instead is taxed as capital gain when
the restricted shares are sold or transferred.

          If you make a Section 83(b) election and the restricted shares are
later forfeited, you are not entitled to a tax deduction or a refund of the tax
already paid.

          The Section 83(b) election must be filed with the Internal Revenue 
Service within 30 days following the date the shares are awarded or sold to 
you. Any ordinary income resulting from the election will be subject to 
applicable tax withholding requirements if you are an employee or former 
employee.  The election generally is not revocable and cannot be made after 
the 30-day period has expired.

          T4.  WHAT ARE THE FEDERAL TAX CONSEQUENCES TO ME IF I RECEIVE A
               DIVIDEND ON THE RESTRICTED SHARES?  

          Dividends received by you on unvested restricted shares are treated as
taxable compensation and are subject to withholding if you are an employee or
former employee.  The Company is entitled to a deduction equal to the amount of
the dividends paid on unvested restricted shares.

          Dividends received on restricted shares subject to a Section 83(b)
election are taxed as dividends instead of compensation.

          T5.  WHAT ARE THE FEDERAL TAX CONSEQUENCES TO THE COMPANY?

          The Company will be entitled to an income tax deduction equal to the
amount of ordinary income you recognize in connection with a restricted share
award.  The deduction will generally be allowed for the taxable year of the
Company in which you recognize such ordinary income.

                            ALTERNATIVE MINIMUM TAX
- ------------------------------------------------------------------------------

          T6.  WHAT IS THE ALTERNATIVE MINIMUM TAX?

          The alternative minimum tax is an alternative method of calculating
the income tax you must pay each year in order to ensure that a minimum amount
of tax is paid for the year.  The first $175,000 ($87,500 for a married taxpayer
filing a separate return) of your alternative minimum taxable income for the
year over the allowable exemption amount is subject to alternative minimum
taxation at the rate of 26%.  The balance of your alternative minimum taxable
income is subject to alternative minimum taxation at the rate of 28%.  The
alternative minimum tax will, however, be payable only to the extent that it
exceeds your regular Federal income tax for the year (computed without regard to
certain credits and special taxes).

          T7.  HOW IS THE ALTERNATIVE MINIMUM TAXABLE INCOME CALCULATED?

          Your alternative minimum taxable income is based upon your regular
taxable income for the year, adjusted to (a) include certain additional items of
income and tax preference and (b) disallow or limit certain deductions otherwise
allowable for regular tax purposes.

          T8.  WHAT IS THE ALLOWABLE EXEMPTION AMOUNT

          The allowable exemption amount is $45,000 for a married taxpayer
filing a joint return, $33,750 for an unmarried taxpayer and $22,500 for a
married taxpayer filing a separate return.  The allowable exemption amount is,
however, reduced by 25CENTS for each $1.00 by which the individual's alternative
minimum taxable income for the year exceeds $150,000 for a married taxpayer
filing a joint return, $112,500 for an unmarried taxpayer, and $75,000 for a
married taxpayer filing a separate return.  Only your income in excess of the
allowable exemption amount is taken into consideration when calculating the
alternative minimum tax.

          T9.  IS THE SPREAD ON AN INCENTIVE OPTION AT THE TIME OF EXERCISE
               NORMALLY INCLUDED IN ALTERNATIVE MINIMUM TAXABLE INCOME?

          Yes.  The spread on an Incentive Option (the excess of the fair market
value of the purchased shares at the time of exercise over the exercise price
paid for those shares) is normally included in the optionee's alternative
minimum taxable income at the time of exercise, whether or not the shares are
subsequently made the subject of a disqualifying disposition.  If there is a
disposition of the Incentive Option shares in the year of exercise via an arm's
length sale or exchange with an unrelated party, the alternative minimum taxable
income is limited to the amount by which the amount realized upon the
disposition of the shares exceeds the exercise price paid for the shares.

          T10. HOW WILL THE PAYMENT OF ALTERNATIVE MINIMUM TAXES IN ONE YEAR
               AFFECT THE CALCULATION OF MY TAX LIABILITY IN A LATER YEAR?

                                      13
<PAGE>

          If you pay alternative minimum taxes for one or more taxable years,
the amount of the taxes so paid (subject to certain adjustments and reductions)
will be applied as a partial credit against your regular tax liability (but not
alternative minimum tax liability) for subsequent taxable years.  In other
words, you can use this credit only to the extent that your regular taxable
income exceeds your alternative minimum taxable income.

          Upon the sale or other disposition of the purchased shares, whether in
the year of exercise or in any subsequent taxable year, your basis for computing
the gain for purposes of alternative minimum taxable income (but not regular
taxable income) will include the amount of the option spread previously included
in your alternative minimum taxable income.  If you pay the regular tax in the
year of disposition, your basis will NOT reflect the alternative minimum taxable
income attributable to the exercise.
