AUTODESK, INC. REGISTRATION STATEMENT ON FORM S-8 PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE. --------------------------------------- There are hereby incorporated by reference in this Registration Statement the following documents and information heretofore filed with the Securities and Exchange Commission: (a) The Company's Annual Report on Form 10-K/A for the fiscal year ended January 31, 1996, filed pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the "1934 Act"); (b) The Company's Quarterly Reports on Form 10-Q for the fiscal quarters ended April 30, 1996 and July 31, 1996, and on Form 10-Q/A for the fiscal quarter ended October 31, 1996 filed pursuant to Section 13 of the 1934 Act; (c) The description of the Company's Common Stock contained in the Company's Registration Statement on Form 8-A dated March 18, 1986 pursuant to Section 12(g) of the 1934 Act. In addition, all documents filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the 1934 Act on or after the date of this Registration Statement and prior to the filing of a post-effective amendment which indicates that all securities offered have been sold or which deregisters all securities then remaining unsold shall be deemed to be incorporated by reference in this Registration Statement and to be 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. -------------------------------------- Mark Bertelsen, a director of the Registrant, is a member of Wilson Sonsini Goodrich & Rosati, which has given an opinion upon the validity of the securities being registered by this Registration Statement. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. ------------------------------------------ As permitted by Section 145 of the Delaware General Corporation Law, the Registrant's Certificate of Incorporation, as amended, includes a provision that eliminates the personal liability of its directors for monetary damages for breach or alleged breach of their duty of care. In addition, as permitted by Section 145 of the Delaware General Corporation Law, the Bylaws of the Registrant provide that: (i) the Registrant is required to indemnify its directors and officers and persons serving in such capacities in other business enterprises (including, for example, subsidiaries of the Registrant) at the Registrant's request, to the fullest extent permitted by Delaware law; (ii) the Registrant may, in its discretion, indemnify employees and agents in those circumstances where indemnification is not required by law; (iii) the Registrant is required to advance expenses, as incurred, to its directors and officers in connection with defending a proceeding, provided that payment of expenses incurred by a director or officer of the corporation in advance of the final disposition of such proceeding shall be made only on receipt of an undertaking by the officer or director to repay all amounts advanced if it should ultimately be determined that the officer or director is not entitled to be indemnified; (iv) the rights conferred in the Bylaws are not exclusive, and the Registrant is authorized to enter into II-1 indemnification agreements with its directors, officers and employees; and (v) the Registrant may not retroactively amend the Bylaw provisions in a way that is adverse to such directors, officers and employees. The Registrant's policy is to enter into indemnification agreements with each of its directors and officers that provide the maximum indemnity allowed to directors and officers by Section 145 of the Delaware General Corporation Law and the Bylaws, as well as certain additional procedural protections. In addition, the indemnification agreements provide that directors and officers will be indemnified to the fullest possible extent permitted by law against all expenses (including attorney's fees) and settlement amounts paid or incurred by them in an action or proceeding, including any action by or in the right of the Registrant, arising out of such person's services as a director or officer of the Registrant, any subsidiary of the Registrant or any other company or enterprise to which such person provides services at the request of the Registrant. The Registrant will not be obligated pursuant to the indemnification agreements to indemnify or advance expenses to an indemnified party with respect to proceedings or claims initiated by the indemnified party and not by way of defense, except with respect to proceedings specifically authorized by the Board of Directors or brought to enforce a right to indemnification under the indemnification agreement, the Registrant's Bylaws or any statute or law. Under the agreements, the Registrant is not obligated to indemnify the indemnified party (i) for any expenses incurred by the indemnified party with respect to any proceeding instituted by the indemnified party to enforce or interpret the agreement, if a court of competent jurisdiction determines that each of the material assertions made by the indemnified party in such proceeding was not made in good faith or was frivolous; (ii) for any amounts paid in settlement of a proceeding unless the Registrant consents to such settlement; (iii) on account of any suit in which judgment is rendered against the indemnified party for an accounting of profits made from the purchase or sale by the indemnified party of securities of the Registrant pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934 and related laws; or (iv) if a final decision by a court having jurisdiction in the matter shall determine that such indemnification is not lawful. The indemnification provisions in the Bylaws and the indemnification agreements entered into between the Registrant and its directors and officers may be sufficiently broad to permit indemnification of the Registrant's directors and officers for liabilities arising under the Securities Act.

UNDERTAKINGS. ------------ A. The Company hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. (2) That, for the purpose of determining any liability under the Securities 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. (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 offering. B. The Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the 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 Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to law, the Company's Articles of Incorporation, the Company's Bylaws or the Company's indemnification agreements, the Company has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Company will, unless in the opinion of its counsel the matter has already been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

                                SOFTDESK, INC.

                            1992 STOCK OPTION PLAN



1.   Purpose.
     ------- 

     The purpose of this plan (the "Plan") is to secure for Softdesk, Inc. (the
"Company") and its shareholders the benefits arising from capital stock
ownership by employees, officers and directors of, and consultants or advisors
to, the Company and its parent and subsidiary corporations who are expected to
contribute to the Company's future growth and success.  Except where the context
otherwise requires, the term "Company" shall include the parent and all present
and future subsidiaries of the Company as defined in Sections 424(e) and 424(f)
of the Internal Revenue Code of 1986, as amended or replaced from time to time
(the "Code"). Those provisions of the Plan which make express reference to
Section 422 shall apply only to Incentive Stock Options (as that term is defined
in the Plan).

2.   Type of Options and Administration.
     ---------------------------------- 

     (a)  Types of Options.  Options granted pursuant to the Plan shall be
          ----------------                                                
authorized by action of the Board of Directors of the Company (or a Committee
designated by the Board of Directors) and may be either incentive stock options
("Incentive Stock Options") meeting the requirements of Section 422 of the Code
or non-statutory options which are not intended to meet the requirements of
Section 422 of the Code.

     (b)  Administration.  The Plan will be administered by the Board of
          --------------                                                
Directors of the Company, whose construction and interpretation of the terms and
provisions of the Plan shall be final and conclusive.  The Board of Directors
may in its sole discretion grant options to purchase shares of the Company's
Common Stock ("Common Stock") and issue shares upon exercise of such options as
provided in the Plan.  The Board shall have authority, subject to the express
provisions of the Plan, to construe the respective option agreements and the
Plan, to prescribe, amend and rescind rules and regulations relating to the
Plan, to determine the terms and provisions of the respective option agreements,
which need not be identical, and to make all other determinations in the
judgment of the Board of Directors necessary or desirable for the administration
of the Plan.  The Board of Directors may correct any defect or supply any
omission or reconcile any inconsistency in the Plan or in any option agreement
in the manner and to the extent it shall deem expedient to carry the Plan into
effect and it shall be the sole and final judge of such expediency.  No director
or person acting pursuant to authority delegated by the Board of Directors shall
be liable for any action or determination under the Plan made in good faith. The
Board of Directors may, to the full extent permitted by or consistent with
applicable laws or regulations (including, without limitation, applicable state
law and Rule 16b-3 promulgated under the Securities Exchange Act of 1934 (the
"Exchange Act"), or any successor rule ("Rule 16b-3")), delegate any or all of
its powers under the Plan to a committee (the "Committee") appointed by the
Board

 
of Directors, and if the Committee is so appointed all references to the Board
of Directors in the Plan shall mean and relate to such Committee.

     (c)  Applicability of Rule 16b-3.  Those provisions of the Plan which make
          ---------------------------                                          
express reference to Rule 16b-3 shall apply only to such persons as are required
to file reports under Section 16(a) of the Exchange Act (a "Reporting Person").

3.   Eligibility.
     ----------- 

     (a)  General.  Options may be granted to persons who are, at the time of
          -------                                                            
grant, employees, officers or directors of, or consultants or advisors to, the
Company; provided, that the class of employees to whom Incentive Stock Options
         --------                                                             
may be granted shall be limited to all employees of the Company.  A person who
has been granted an option may, if he or she is otherwise eligible, be granted
additional options if the Board of Directors shall so determine.

     (b)  Grant of Options to Directors and Officers.  From and after the
          ------------------------------------------                     
registration of the Common Stock of the Company under the Exchange Act, the
selection of a director or an officer (as the terms "director" and "officer" are
defined for purposes of Rule 16b-3) as a recipient of an option, the timing of
the option grant, the exercise price of the option and the number of shares
subject to the option shall be determined either (i) by the Board of Directors,
of which all members shall be "disinterested persons" (as hereinafter defined),
or (ii) by two or more directors having full authority to act in the matter,
each of whom shall be a "disinterested person."  For the purposes of the Plan, a
director shall be deemed to be a "disinterested person" only if such person
qualifies as a "disinterested person" within the meaning of Rule 16b-3, as such
term is interpreted from time to time.

4.   Stock Subject to Plan.
     --------------------- 

     Subject to adjustment as provided in Section 15 below, the maximum number

terminate for any reason without having been exercised in full, the unpurchased
shares subject to such option shall again be available for subsequent option
grants under the Plan.

5.   Forms of Option Agreements.
     -------------------------- 

     As a condition to the grant of an option under the Plan, each recipient of
an option shall execute an option agreement In such form not inconsistent with
the Plan as may be approved by the Board of Directors.  Such option agreements
may differ among recipients.

exercise of an option shall be determined by the Board of Directors; provided,
                                                                     -------- 
however, that in the case of an Incentive Stock Option, the exercise price shall
not be less than 100% of the fair market value of such stock, as 

                                      -2-

 
determined by the Board of Directors, at the time of grant of such option, or
less than 110% of such fair market value in the case of options described in
Section 11(b).

     (b)  Payment of Purchase Price.  Options granted under the Plan may provide
          -------------------------                                             
for the payment of the exercise price by delivery of cash or a check to the
order of the Company in an amount equal to the exercise price of such options,
or, to the extent provided in the applicable option agreement, (i) by delivery
to the Company of shares of Common Stock of the Company already owned by the
optionee having a fair market value equal in amount to the exercise price of the
options being exercised, (ii) by any other means (including, without limitation,
by delivery of a promissory note of the optionee payable on such terms as are
specified by the Board of Directors) which the Board of Directors determines are
consistent with the purpose of the Plan and with applicable laws and regulations
(including, without limitation, the provisions of Rule 16b-3 and Regulation T
promulgated by the Federal Reserve Board) or (iii) by any combination of such
methods of payment. The fair market value of any shares of the Company's Common
Stock or other non-cash consideration which may be delivered upon exercise of an
option shall be determined by the Board of Directors.

7.   Option Period.
     ------------- 

     Each option and all rights thereunder shall expire on such date as shall be
set forth in the applicable option agreement, except that, in the case of an
Incentive Stock Option, such date shall not be later than ten years after the
date on which the option is granted and, in all cases, options shall be subject
to earlier termination as provided in the Plan.

8.   Exercise of Options.
     ------------------- 

     Each option granted under the Plan shall be exercisable either in full or

     Incentive Stock Options, and all options granted to Reporting Persons,
shall not be assignable or transferable by the person to whom they are granted,
either voluntarily or by operation of law, except by will or the laws of descent

determine the period of time during which an optionee may exercise an option
following (i) the termination of the optionee's employment or other relationship
with the Company or (ii) the death or disability of the optionee.  Such periods
shall be set forth in the agreement evidencing such option.

of stock ownership rules of Section 424(d) of the Code), then the following
special provisions shall be applicable to the Incentive Stock Option granted to
such individual:

          (i)    The purchase price per share of the Common Stock subject to
     such Incentive Stock Option shall not be less than 110% of the fair market
     value of one share of Common Stock at the time of grant; and

          (ii)   the option exercise period shall not exceed five years from the
     date of grant.

     (c)  Dollar Limitation.  For so long as the Code shall so provide, options
          -----------------                                                    
granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended to constitute Incentive Stock Options
shall not constitute Incentive Stock Options to the extent that such options, in
the aggregate, become exercisable for the first time in any one calendar year
for shares of Common Stock with an aggregate fair market value (determined as of
the respective date or dates of grant) of more than $100,000.

     (d)  Termination of Employment, Death or Disability.  No Incentive Stock
          ----------------------------------------------                     
Option may be exercised unless, at the time of such exercise, the optionee is,
and has been continuously since the date of grant of his or her option, employed
by the Company, except that:

          (i)    an Incentive Stock Option may be exercised within the period of
     three months after the date the optionee ceases to be an employee of the
     Company (or within such lesser period as may be specified in the applicable
     option agreement); provided, that the agreement with respect to such option
                        --------                                                
     may designate a longer exercise period and that the exercise after such
     three-month period shall be treated as the exercise of a non-statutory
     option under the Plan;

          (ii)   if the optionee dies while in the employ of the Company, or
     within three months after the optionee ceases to be such an employee, the
     Incentive Stock Option may be exercised by the person to whom it is
     transferred by will or the laws of descent and distribution within the
     period of one year after the date of death (or within such lesser period as
     may be specified in the applicable option agreement); and

                                      -4-

 
          (iii)  if the optionee becomes disabled (within the meaning of Section
     22(e)(3) of the Code or any successor provision thereto) while in the
     employ of the Company, the Incentive Stock Option may be exercised within
     the period of one year after the date the optionee ceases to be such an
     employee because of such disability (or within such lesser period as may be
     specified in the applicable option agreement).

For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations).  Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

12.  Additional Provisions.
     --------------------- 

     (a)  Additional Option Provisions.  The Board of Directors may, in its sole
          ----------------------------                                          
discretion, include additional provisions in option agreements covering options
granted under the Plan, including without limitation restrictions on transfer,
repurchase rights, commitments to pay cash bonuses, to make, arrange for or
guaranty loans or to transfer other property to optionees upon exercise of
options, or such other provisions as shall be determined by the Board of
Directors; provided that such additional provisions shall not be inconsistent
           --------                                                          
with any other term or condition of the Plan and such additional provisions
shall not cause any Incentive Stock Option granted under the Plan to fail to
qualify as an Incentive Stock Option within the meaning of Section 422 of the
Code.

     (b)  Acceleration, Extension, Etc.  The Board of Directors may, in its sole
          ----------------------------                                          
discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the
dates during which all, or any particular, option or options granted under the
Plan may be exercised; provided, however, that no such extension shall be
                       -----------------                                 
permitted if it would cause the Plan to fail to comply with Section 422 of the
Code or with Rule 16b-3.

13.  General Restrictions.
     -------------------- 

     (a)  Investment Representations.  The Company may require any person to 
          --------------------------   
whom an option is granted, as a condition of exercising such option, to give
written assurances in substance and form satisfactory to the Company to the
effect that such person is acquiring the Common Stock subject to the option for
his or her own account for investment and not with any present intention of
selling or otherwise distributing the same, and to such other effects as the
Company deems necessary or appropriate in order to comply with federal and
applicable state securities laws, or with covenants or representations made by
the Company in connection with any public offering of its Common Stock.

     (b)  Compliance With Securities Laws.  Each option shall be subject to the
          -------------------------------                                      
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the shares subject to such option
upon any securities exchange or under any state or federal law, or the consent
or approval of any governmental or regulatory body, or that the disclosure of
non-public information or the satisfaction of any other condition is necessary
as a condition of, or in connection with, the issuance or purchase of shares
thereunder, such option may not be exercised, in whole or in part, 

                                      -5-

 
unless such listing, registration, qualification, consent or approval, or
satisfaction of such condition shall have been effected or obtained on
conditions acceptable to the Board of Directors.  Nothing herein shall be deemed
to require the Company to apply for or to obtain such listing, registration or
qualification, or to satisfy such condition.

14.  Rights as a Shareholder.
     ----------------------- 

     The holder of an option shall have no rights as a shareholder with respect
to any shares covered by the option (including, without limitation, any rights
to receive dividends or non-cash distributions with respect to such shares)
until the date of issue of a stock certificate to him or her for such shares.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such stock certificate is issued.

15.  Adjustment Provisions for Recapitalizations and Related Transactions.
     -------------------------------------------------------------------- 

     (a)  General.  If, through or as a result of any merger, sale of all or
          -------                                                           
substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar transaction, (i) the outstanding shares of Common Stock
are increased, decreased or exchanged for a different number or kind of shares
or other securities of the Company, or (ii) additional shares or new or
different shares or other securities of the Company or other non-cash assets are
distributed with respect to such shares of Common Stock or other securities, an
appropriate and proportionate adjustment may be made in (x) the maximum number
and kind of shares reserved for issuance under the Plan, (y) the number and kind
of shares or other securities subject to any then outstanding options under the
Plan, and (z) the price for each share subject to any then outstanding options
under the Plan, without changing the aggregate purchase price as to which such
options remain exercisable.  Notwithstanding the foregoing, no adjustment shall
be made pursuant to this Section 15 if such adjustment would cause the Plan to
fail to comply with Section 422 of the Code or with Rule 16b-3.

     (b)  Board Authority to Make Adjustments.  Any adjustments under this
          -----------------------------------                             
Section 15 shall be made by the Board of Directors, whose determination as to
what adjustments, if any, shall be made and the extent thereof shall be final,
binding and conclusive.  No fractional shares shall be issued under the Plan on
account of any such adjustments.

16.  Merger, Consolidation, Asset Sale, Liquidation, etc.
     --------------------------------------------------- 

     (a)  General.  In the event of a consolidation or merger or sale of all or
          -------                                                              
substantially all of the assets of the Company in which outstanding shares of
Common Stock are exchanged for securities, cash or other property of any other
corporation or business entity or in the event of a liquidation of the Company,
the Board of Directors of the Company, or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions, as to outstanding options:  (i)
provide that such options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof); provided, that any such options substituted for Incentive Stock
          --------                                                       
Options shall meet the requirements of Section 424(a) of the Code, (ii) upon
written notice to the optionees, provide that all unexercised options will
terminate 

                                      -6-

 
immediately prior to the consummation of such transaction unless exercised by
the optionee within a specified period following the date of such notice, (iii)
in the event of a merger under the terms of which holders of the Common Stock of
the Company will receive upon consummation thereof a cash payment for each share
surrendered in the merger (the "Merger Price"), make or provide for a cash
payment to the optionees equal to the difference between (A) the Merger Price
times the number of shares of Common Stock subject to such outstanding options
(to the extent then exercisable at prices not in excess of the Merger Price) and
(B) the aggregate exercise price of all such outstanding options in exchange for
the termination of such options, and (iv) provide that all or any outstanding
options shall become exercisable in full immediately prior to such event.

     (b)  Substitute Options.  The Company may grant options under the Plan in
          ------------------                                                  
substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company, or
one of its subsidiaries, of property or stock of the employing corporation.  The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

17.  No Special Employment Rights.
     ---------------------------- 

     Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment by
the Company or interfere in any way with the right of the Company at any time to
terminate such employment or to increase or decrease the compensation of the
optionee.

18.  Other Employee Benefits.
     ----------------------- 

     Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise will not constitute compensation with respect to which any
other employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

19.  Amendment of the Plan.
     --------------------- 

     (a)  The Board of Directors may at any time, and from time to time, modify
or amend the Plan in any respect, except that if at any time the approval of the
shareholders of the Company is required under Section 422 of the Code or any
successor provision with respect to Incentive Stock Options, or under Rule 16b-
3, the Board of Directors may not effect such modification or amendment without
such approval.

     (b)  The termination or any modification or amendment of the Plan shall
not, without the consent of an optionee, affect his or her rights under an
option previously granted to him or her.  With

                                      -7-

 
the consent of the optionee affected, the Board of Directors may amend
outstanding option agreements in a manner not inconsistent with the Plan.

20.  Withholding.
     ----------- 

     (a)  The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan.  Subject to the prior approval of the Company, which
may be withheld by the Company in its sole discretion, the optionee may elect to
satisfy such obligations, in whole or in part, (i) by causing the Company to
withhold shares of Common Stock otherwise issuable pursuant to the exercise of
an option or (ii) by delivering to the Company shares of Common Stock already
owned by the optionee.  The shares so delivered or withheld shall have a fair
market value equal to such withholding obligation.  The fair market value of the
shares used to satisfy such withholding obligation shall be determined by the
Company as of the date that the amount of tax to be withheld is to be
determined.  An optionee who has made an election pursuant to this Section 20(a)
may only satisfy his or her withholding obligation with shares of Common Stock
which are not subject to any repurchase, forfeiture, unfulfilled vesting or
other similar requirements.

     (b)  Notwithstanding the foregoing, in the case of a Reporting Person, no
election to use shares for the payment of withholding taxes shall be effective
unless made in compliance with any applicable requirements of Rule 16b-3.

21.  Cancellation and New Grant of Options, Etc.
     ------------------------------------------ 

     The Board of Directors shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, (i) the
cancellation of any or all outstanding options under the Plan and the grant in
substitution therefor of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
cancelled options or (ii) the amendment of the terms of any and all outstanding
options under the Plan to provide an option exercise price per share which is
higher or lower than the then-current exercise price per share of such
outstanding options.

22.  Effective Date and Duration of the Plan.
     --------------------------------------- 

     (a)  Effective Date.  The Plan shall become effective when adopted by the
          --------------                                                      
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve months after the date of the Board's adoption of the Plan, no options
previously granted under the Plan shall be deemed to be Incentive Stock Options
and no Incentive Stock Options shall be granted thereafter.  Amendments to the
Plan not requiring shareholder approval shall become effective when adopted by
the Board of Directors; amendments requiring shareholder approval (as provided
in Section 19) shall become effective when adopted by the Board of Directors,
but no Incentive Stock Option granted after the date of such amendment shall
become exercisable (to the extent that such amendment to the Plan was required
to enable the Company to grant such Incentive Stock Option to a 

                                      -8-

 
particular optionee) unless and until such amendment shall have been approved by
the Company's shareholders.  If such shareholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any Incentive Stock
Options granted on or after the date of such amendment shall terminate to the
extent that such amendment to the Plan was required to enable the Company to
grant such option to a particular optionee.  Subject to this limitation, options
may be granted under the Plan at any time after the effective date and before
the date fixed for termination of the Plan.

     (b)  Termination.  Unless sooner terminated in accordance with Section 16,
          -----------                                                          
the Plan shall terminate, with respect to Incentive Stock Options, upon the
earlier of (i) the close of business on the day next preceding the tenth
anniversary of the date of its adoption by the Board of Directors, or (ii) the
date on which all shares available for issuance under the Plan shall have been
issued pursuant to the exercise or cancellation of options granted under the
Plan.  Unless sooner terminated in accordance with Section 16, the Plan shall
terminate with respect to options which are not Incentive Stock Options on the
date specified in (ii) above.  If the date of termination is determined under
(i) above, then options outstanding on such date shall continue to have force
and effect in accordance with the provisions of the instruments evidencing such
options.

23.  Provision for Foreign Participants.
     ---------------------------------- 

     The Board of Directors may, without amending the Plan, modify awards or
options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters.

                                      -9-

 
                                                                     EXHIBIT 4.2

shall be final and conclusive.  Grants of stock options under the Plan and the
amount and nature of the awards to be granted shall be automatic and non-
discretionary in accordance with Section 5.  However, all questions of
interpretation of the Plan or of any options issued under it shall be determined
by the Board of Directors and such determination shall be final and binding upon
all persons having an interest in the Plan.  No director shall be liable for any
action or determination under the Plan made in good faith.

terminated without having been exercised in full, the shares allocable to the
unexercised portion of such option shall again become available for grant
pursuant to the Plan.

     (c)  All options granted under the Plan shall be nonstatutory options which
are not intended to meet the requirements of Section 422 of the Internal Revenue

     shares of Common Stock on the date of his or her initial election to the
     Board of Directors.

     (b)  Option Exercise Price.  The option exercise price per share for each
     option granted under the Plan shall equal the last reported sale price per
     share of the Company's Common Stock on the National Market (or such other
     national securities exchange or trading system of which the Common Stock
     may then be listed or quoted) on the date of grant (or if no such price is
     reported on such date, such price is reported on the nearest preceding date
     on which such price is reported).

     (c)  Options Non-Transferable.  Each option granted under the Plan by its
     terms shall not be transferable by the optionee otherwise than by will or
     by the laws of descent and distribution, or pursuant to a qualified
     domestic relations order (as defined in Section 414(p) of the Code) and
     shall be exercised during the lifetime of the optionee only by such
     optionee.

     (d)  Vesting.  Each option will vest in equal annual installments on the
     anniversary of the date of grant over a three-year period, provided the
     option holder continues to serve as a director of the Company.

     time to time, in whole or in part, prior to the fifth anniversary of the

     to the Company at its principal office accompanied by payment of the full
     consideration for the shares as to which they are exercised.

     (g)  Payment of Purchase Price.  Payment of the exercise price may be made,
     at the election of the optionee, (i) by delivery of cash or a check to the
     order of the Company in an amount equal to the exercise price, (ii) by
     delivery to the Company of shares of Common Stock of the Company already
     owned and held by the optionee for at least twelve months and having a fair
     market value equal in amount to the exercise price of the options being
     exercised, or (iii) by any combination of such methods of payment.  The
     fair market value of any shares of Common Stock which may be delivered upon
     exercise of an option shall be determined by the Company as of the date
     that such shares are delivered.

provided in Section 5.

7.   TIME FOR GRANTING OPTIONS.

8.   LIMITATION OF RIGHTS.

     (a)  No Right to Continue as a Director.  Neither the Plan, nor the
granting of an option nor any other action taken pursuant to the Plan, shall
constitute or be evidence of any agreement or understanding, express or implied,
that the Company will retain a director for any period of time.

     (b)  No Stockholder Rights for Options.  An optionee shall have no rights
as a stockholder with respect to the shares covered by his or her option until
the date of the issuance to him or her of a stock certificate there for, and no
adjustment will be made for dividends or other rights for which the record date
is prior to the date such certificate is issued.

9.   ADJUSTMENT PROVISIONS.

     (a)  Recapitalizations.  If, through or as a result of any merger,
consolidation, sale of all or substantially all of the assets of the Company,
reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split or other similar transaction, (i) the outstanding shares of
Common Stock are increased or decreased or are exchanged for a different number
or kind of shares or other securities of the Company, or (ii) additional shares
or new or different shares or other securities of the Company or other non-cash
assets are distributed with respect to such shares of Common Stock or other
securities, an appropriate and proportionate adjustment shall be made in (w) the
maximum number and kind of shares reserved for issuance under the Plan, (x) the
number and kind of shares or other securities subject to future option grants
under the Plan, (y) the number and kind of shares or other securities subject to
then outstanding options under the Plan, and (z) the price for each share
subject to any then outstanding options under the Plan, without changing the
aggregate purchase price as to which such options remain exercisable, provided
that no adjustment shall be made pursuant to this Section 9 if such adjustment
would cause the Plan to fail to comply with Rule 16-b-3 under the Securities
Exchange Act of 1934 (the "Exchange Act"), or any successor rule ("Rule 16-b-3")

     (b)  Mergers.  In the event of a consolidation or merger in which
outstanding shares of Common Stock are exchanged for securities, cash or other
property of any other corporation or business entity or in the event of a
liquidation of the Company or sale of all or substantially all of the assets of
the Company, the Board of Directors of the Company, or the board of directors of
any corporation assuming the obligations of the Company, shall take any one or
more of the following actions, as to outstanding options:  (i) provide that such
options shall be assumed, or equivalent options shall be substituted, by the
acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written
notice to the optionees, provide that all unexercised options will terminate
immediately prior to the consummation of such transaction unless exercised by
the optionee within a specified period following the date of such notice, or
(iii) in the event of a merger under the terms of which holders of the Common
Stock of the Company will receive upon consummation thereof a cash payment for
each share surrendered in the merger (the "Merger Price"), make or provide for a
cash payment to the optionees equal to the difference between (A) the Merger
Price times the number of shares of Common Stock subject to such outstanding
options (to the extent then exercisable at prices not in excess of the Merger
Price) and (B) the aggregate exercise price of all such outstanding options in
exchange for the termination of such options.

                                      -3-

 
10.  AMENDMENT OF THE PLAN.

     (a)  The provisions of Sections 3, 5(a) and 5(b) of the Plan shall not be
amended more than once every six months, other than to comport with changes in
the Code, the Employee Retirement Income Security Act of 1974, or the rules
thereunder.  Subject to the foregoing, the Board of Directors may at any time,
and from time to time, modify or amend the Plan in any respect, except that if
at any time the approval of the stockholders of the Company is required as to
such modification or amendment under Rule 16-b-3, the Board of Directors may not
effect such modification or amendment without such approval.

     (b)  The termination or any modification or amendment of the Plan shall
not, without the consent of the optionee, affect his or her rights under an
option previously granted to him or her.  With the consent of the optionees
affected, the Board of Directors may amend outstanding option agreements in a
manner not inconsistent with the Plan.  The Board of Directors shall have the
right to amend or modify the terms and provisions of the Plan and of any
outstanding option to the extent necessary to ensure the qualification of the
Plan under Rule 16-b-3.

11.  WITHHOLDING.

     The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan. Subject to the prior approval of the Company, which
may be withheld by the Company in its sole discretion, the optionee may elect to
satisfy such obligations, in whole or in part, (i) by causing the Company to
withhold shares of Common Stock otherwise issuable pursuant to the exercise of
an option or (ii) by delivering to the Company shares of Common Stock already
owned by the optionee.  The shares so delivered or withheld shall have a fair
market value equal to such withholding obligation.  The fair market value of the
shares used to satisfy such withholding obligation shall be determined by the
Company as of the date that the amount of tax to be withheld is to be
determined.  An optionee who has made an election pursuant to this Section 11
may only satisfy his or her withholding obligation with shares of Common Stock
which are not subject to any repurchase, forfeiture, unfulfilled vesting or
other similar requirements.  Notwithstanding the foregoing, no election to use
shares for the payment of withholding taxes shall be effective unless made in
compliance with any applicable requirements of Rule 16-b-3.

12.  NOTICE.

     Any written notice to the Company required by any of the provisions of the
Plan shall be addressed to the Chief Executive Officer of the Company and shall
become effective when it is received.

13.  EFFECTIVE DATE AND DURATION OF THE PLAN.

     (a)  Effective Date.  The Plan shall become effective when adopted by the
Board of Directors, but no option granted under the Plan shall become
exercisable unless and until the Plan shall have been approved by the Company's
stockholders.   If such stockholder approval is not obtained within twelve

                                      -4-

 
months after the date of the Board's adoption of the Plan, all options granted
under the Plan shall terminate and no further options shall be granted under the
Plan.  Amendments to the Plan not requiring stockholder approval shall become
effective when adopted by the Board of Directors; amendments requiring
stockholder approval (as provided in Section 10(a)) shall become effective when
adopted by the Board of Directors, but no option issued after the date of such
amendment shall become exercisable (to the extent that such amendment to the
Plan was required to enable the Company to grant such option to a particular
optionee) unless and until such amendment shall have been approved by the
Company's stockholders. If such stockholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any options granted on
or after the date of such amendment shall terminate to the extent that such
amendment to the Plan was required to enable the Company to grant such option to
a particular optionee.  Subject to this limitation, options may be granted under
the Plan at any time after the effective date and before the date fixed for
termination of the Plan.

     (b)  Termination.  Unless earlier terminated pursuant to Section 9, the
Plan shall terminate upon the earlier of (i) November 24, 1998, or (ii) the date
on which all shares available for issuance under the Plan shall have been issued
pursuant to the exercise of options granted under the Plan.  If the date of
termination is determined under (i) above, then options outstanding on such date
shall continue to have force and effect in accordance with the provisions of the
instruments evidencing such options.

14.  GENERAL RESTRICTIONS.

     (a)  Investment Representations.  The Company may require any person to
whom an option is granted, as a condition of exercising such option, to give
written assurances in substance and form satisfactory to the Company to the
effect that such person is acquiring the Common Stock subject to the option for
his or her own account for investment and not with any present intention of
selling or otherwise distributing the same, and to such other effects as the
Company deems necessary or appropriate in order to comply with federal and
applicable state securities laws.

     (b)  Compliance With Securities Laws.  Each option shall be subject to the
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the shares subject to such option
upon any securities exchange or under any state or federal law, or the consent
or approval of any governmental or regulatory body, or that the disclosure of
non-public information or the satisfaction of any other condition is necessary
as a condition of, or in connection with, the issuance or purchase of shares
thereunder, such option may not be exercised, in whole or in part, unless such
listing, registration, qualification, consent or approval, or satisfaction of
such condition shall have been effected or obtained on terms acceptable to the
Board of Directors.  Nothing herein shall be deemed to require the Company to
apply for or to obtain such listing, registration or qualification, or to
satisfy such condition.

shall be authorized by action of the Board of Directors of the Company (or a
Committee designated by the Board of Directors) and may be either incentive
stock options ("Incentive Stock Options") meeting the requirements of Section

requirements of Section 422 of the Code. Awards granted pursuant to the Plan
shall be authorized by action of the Board of Directors of the Company (or a
Committee designated by the Board of Directors) and shall meet the requirements

Directors of the Company, whose construction and interpretation of the terms and
provisions of the Plan shall be final and conclusive.  The Board of Directors

Common Stock (as defined in Section 4 of the Plan), and issue shares upon
exercise of such options as provided in the Plan and (ii) make awards for the

terms and provisions of the respective option agreements and awards, which need
not be identical, and to make all other determinations in the judgment of the
Board of Directors necessary or desirable for the administration of the Plan.
The Board of Directors may correct any defect or supply any omission or
reconcile any inconsistency in the Plan or in any option agreement or award in
the manner and to the extent it shall deem expedient to carry the Plan into
effect and it shall be the sole and final judge of such expediency.  No director
or person acting pursuant to authority delegated by the Board of Directors shall
be liable for any action or determination made in good faith.  The Board of
Directors may, to the full extent permitted by or consistent with applicable
laws or regulations (including, without limitation, applicable state law and
Rule 16b-3 promulgated under the Securities Exchange Act of 1934 (the "Exchange
Act"), or any successor rule ("Rule 16b-3"))/1/ delegate any or all of its
powers under the Plan to a committee (the "Committee") appointed by the Board of
Directors, and if the Committee is so appointed all references to the Board of

 
Directors in the Plan shall mean and relate to such Committee to the extent
authority is so delegated to such Committee.

     (c)  Applicability of Rule 16b-3.  Those provisions of the Plan which make
          ---------------------------

officers and directors are also employees) of, or consultants or advisors to,
the Company; provided, that the class of employees to whom Incentive Stock
             --------
Options may be granted shall be limited to all employees of the Company; and 
provided further that from the date on which the Company first has its Common 
- -------- -------
Stock registered under the Exchange Act, non-employee directors of the Company

Plan. A person who has been granted an option or award may, if he or she is
otherwise eligible, be granted additional options or awards if the Board of
Directors shall so determine.

     (b)  Grant of Options to Directors and Officers.  The selection of a
          ------------------------------------------                     
director or an officer (as the terms "director" and "officer" are defined for
purposes of Rule 16b-3) as a participant, the timing of the option grant or
award, the exercise price of the option or the sale price of the award and the
number of shares for which an option or award may be granted to such director or
officer shall be determined either (i) by the Board of Directors, of which all
members shall be "disinterested persons" (as hereinafter defined), or (ii) by a
committee of two or more directors having full authority to act in the matter,
of which all members shall be "disinterested persons."  For the purposes of the
Plan, a director shall be deemed to be "disinterested" only if such person

     --------------------------------------- 

     (a)  General.  The purchase price per share of Common Stock deliverable 
          -------

provided, however, that in the case of an Incentive Stock Option, the exercise
- --------  -------                                                             
price shall not be less than 100% of the fair market value of such stock, as
determined by the Board of Directors, at the time of grant of such option, or
less than 110% of such fair market value in the case of options described in
Section 11(b).

     (b)  Payment of Purchase Price.  Options granted under the Plan may provide
          -------------------------                                             
for the payment of the exercise price by delivery of cash or a check to the
order of the Company in an amount equal to the exercise price of such options,
or, to the extent provided in the applicable option agreement, (i) by delivery
to the Company of shares of Common Stock of the Company already owned by the
optionee having a fair market value equal in amount to the exercise price of the
options being exercised, (ii) by any other means (including without limitation
by delivery of a promissory note of the optionee payable on such terms as are
specified by the Board of Directors) which the Board of Directors determines are
consistent with the purpose of the Plan and with applicable laws and regulations
(including, without limitation, the provisions of Rule 16b-3 and Regulation T
promulgated by the Federal Reserve Board) or (iii) by any combination of such
methods of payment. The fair market value of any shares of the Company's Common
Stock or other non-cash consideration which may be delivered upon exercise of an
option shall be determined in such manner as may be prescribed by the Board of
Directors.

7.   Option Period.
     ------------- 

     Each option and all rights thereunder shall expire on such date as shall be
set forth in the applicable option agreement, except that such date, in the case
of an Incentive Stock Option, shall in no case be later than ten years after the
date on which the option is granted.

8.   Exercise of Options.
     ------------------- 

     Each option granted under the Plan shall be exercisable either in full or
in installments at such time or times and during such period as shall be set
forth in the agreement evidencing such option, subject to the provisions of the
Plan.

9.   Nontransferability of Options.
     ----------------------------- 

     Incentive Stock Options, and all options granted to Reporting Persons,
shall not be assignable or transferable by the person to whom it is granted,
either voluntarily or by operation of law, except by will or the laws of descent
and distribution, and, during the life of the optionee, shall be exercisable
only by the optionee; provided, however, that non-statutory options granted to
Reporting Persons may be transferred pursuant to a qualified domestic relations
order (as defined in Rule 16b-3).

                                      -3-

     --------------------------------------------------------- 

     The Board of Directors shall determine the period of time during which an
optionee may exercise an option following (i) the termination of the optionee's

disability of the optionee. Such periods shall be set forth in the agreement
evidencing such option.

11.  Incentive Stock Options.
     ----------------------- 

     Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:

     (a)  Express Designation.  All Incentive Stock Options granted under the
          -------------------                                                
Plan shall, at the time of grant, be specifically designated as such in the
option agreement covering such Incentive Stock Options.

     (b)  10% Shareholder.  If any employee to whom an Incentive Stock Option is
          ---------------                                                       
to be granted under the Plan is, at the time of the grant of such option, the
owner of stock possessing more than 10% of the total combined voting power of
all classes of stock of the Company (after taking into account the attribution
of stock ownership rules of Section 424(d) of the Code), then the following
special provisions shall be applicable to the Incentive Stock Option granted to
such individual:

          (i)    The purchase price per share of the Common Stock subject to
     such Incentive Stock Option shall not be less than 110% of the fair market
     value of one share of Common Stock at the time of grant; and

          (ii)   The option exercise period shall not exceed five years from the
     date of grant.

     (c)  Dollar Limitation.  For so long as the Code shall so provide, options
          -----------------                                                    
granted to any employee under the Plan (and any other incentive stock option
plans of the Company) which are intended to constitute Incentive Stock Options
shall not constitute Incentive Stock Options to the extent that such options, in
the aggregate, become exercisable for the first time in any one calendar year
for shares of Common Stock with an aggregate fair market value (determined as of
the respective date or dates of grant) of more than $100,000.

     (d)  Termination of Employment, Death or Disability.  No Incentive Stock
          ----------------------------------------------                     
Option may be exercised unless, at the time of such exercise, the optionee is,
and has been continuously since the date of grant of his or her option, employed
by the Company, except that:

          (i)    an Incentive Stock Option may be exercised within the period of
     three months after the date the optionee ceases to be an employee of the
     Company (or within such lesser period as may be specified in the applicable
     option agreement), provided, that the agreement with respect to such option
                        --------                                                
     may designate a longer exercise period and that the exercise after such
     three-month period shall be treated as the exercise of a non-statutory
     option under the Plan;

                                      -4-

 
          (ii)   if the optionee dies while in the employ of the Company, or
     within three months after the optionee ceases to be such an employee, the
     Incentive Stock Option may be exercised, by the person to whom it is
     transferred by will or the laws of descent and distribution, within the
     period of one year after the date of death (or within such lesser period as
     may be specified in the applicable option agreement); and

          (iii)  if the optionee becomes disabled (within the meaning of Section
     22(e)(3) of the Code or any successor provision thereto) while in the
     employ of the Company, the Incentive Stock Option may be exercised within
     the period of one year after the date the optionee ceases to be such an
     employee because of such disability (or within such lesser period as may be
     specified in the applicable option agreement).

For all purposes of the Plan and any option or award granted hereunder,
"employment" shall be defined in accordance with the provisions of Section
1.421-7(h) of the Income Tax Regulations (or any successor regulations).
Notwithstanding the foregoing provisions, no stock option may be exercised after
its expiration date.

12.  Additional Provisions.
     --------------------- 

     (a)  Additional Option Provisions.  The Board of Directors may, in its sole
          ----------------------------                                          
discretion, include additional provisions in any option granted under the Plan,
including without limitation restrictions on transfer, repurchase rights,
commitments to pay cash bonuses, to make, arrange for or guaranty loans or to
transfer other property to optionees upon exercise of options, or such other
provisions as shall be determined by the Board of Directors; provided that such
additional provisions shall not be inconsistent with any other term or condition
of the Plan.

     (b)  Acceleration, Extension, Etc.  The Board of Directors may, in its sole
          -----------------------------                                         
discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the
dates during which all or any particular option or options granted under the
Plan may be exercised; provided, however, that no such extension shall be
permitted if it would cause the Plan to fail to comply with Section 422 of the
Code or with Rule 16b-3.

13.  Awards.
     ------ 

     A restricted stock award ("award") shall consist of the sale and issuance
by the Company of shares of Common Stock, and purchase by the recipient of such
shares, subject to the terms, conditions and restrictions described in the
document evidencing the award and in this Section 13 and elsewhere in the Plan.

     (a)  Execution of Restricted Stock Award Agreement.  As a condition to an
          ---------------------------------------------                       
award under the Plan, each recipient of an award shall execute an agreement in
such form, which may differ among recipients, as shall be specified by the Board
of Directors at the time of such award.

     (b)  Price.  The Board of Directors shall determine the price at which
          -----                                                            
shares of Common Stock 

                                      -5-

 
shall be sold to recipients of awards under the Plan.  The Board of Directors
may, in its discretion, issue shares pursuant to awards without the payment of
any cash purchase price by the recipients or issue shares pursuant to awards at
a purchase price below the then fair market value of the Common Stock.  If a
purchase price is required to be paid, it shall be paid in cash or by check
payable to the order of the Company at the time that the award is accepted by
the recipient, or by such other means as may be approved by the Board of
Directors.

     (c)  Number of Shares.  The award shall specify the number of shares of
          ----------------                                                  
Common Stock granted thereunder.

     (d)  Restrictions on Transfer.  In addition to such other terms, conditions
          ------------------------                                              
and restrictions upon awards as shall be imposed by the Board of Directors, all
shares issued pursuant to an award shall be subject to the following
restrictions:

          (1)  All shares of Common Stock subject to an award (including any
     shares issued pursuant to paragraph (e) of this Section) shall be subject
     to certain restrictions on disposition and obligations of resale to the
     Company as provided in subparagraph (2) below for the period specified in
     the document evidencing the award, and shall not be sold, assigned,
     transferred, pledged, hypothecated or otherwise disposed of until such
     restrictions lapse.  The period during which such restrictions are
     applicable is referred to as the Restricted Period.

          (2)  In the event that a recipient's employment with the Company (or
     consultancy or advisory relationship, as the case may be) is terminated
     within the Restricted Period, whether such termination is voluntary or
     involuntary, with or without cause, or because of the death or disability
     of the recipient, the Company shall have the right and option for a period
     of three months following such termination to buy for cash that number of
     the shares of Common Stock purchased under the award as to which the
     restrictions on transfer and the forfeiture provisions contained in the
     award have not then lapsed, at a price equal to the price per share
     originally paid by the recipient.  If such termination occurs within the
     last three months of the applicable restrictions, the restrictions and
     repurchase rights of the Company shall continue to apply until the
     expiration of the Company's three month option period.

          (3)  Notwithstanding subparagraphs (1) and (2) above, the Board of
     Directors may, in its discretion, either at the time that an award is made
     or at any time thereafter, waive its right to repurchase shares of Common
     Stock upon the occurrence of any of the events described in this paragraph
     (d) or remove or modify any part or all of the restrictions.  In addition,
     the Board of Directors may, in its discretion, impose upon the recipient of
     an award at the time of such award such other restrictions on any shares of
     Common Stock issued pursuant to such award as the Board of Directors may
     deem advisable.

                                      -6-

 
     (e)  Additional Shares.  Any shares received by a recipient of an award 
          -----------------   
as a stock dividend on, or as a result of stock splits, combinations, exchanges
of shares, reorganizations, mergers, consolidations or otherwise with respect
to, shares of Common Stock received pursuant to such award shall have the same
status and shall bear the same restrictions, all on a proportionate basis, as
the shares initially purchased pursuant to such award.

     (f)  Transfers in Breach of Award.  If any transfer of shares purchased
          ----------------------------                                      
pursuant to an award is made or attempted contrary to the terms of the Plan and
of such award, the Board of Directors shall have the right to purchase for the
account of the Company those shares from the owner thereof or his or her
transferee at any time before or after the transfer at the price paid for such
shares by the person to whom they were awarded under the Plan.  In addition to
any other legal or equitable remedies which it may have, the Company may enforce
its rights by specific performance to the extent permitted by law. The Company
may refuse for any purpose to recognize as a shareholder of the Company any
transferee who receives any shares contrary to the provisions of the Plan and
the applicable award or any recipient of an award who breaches his or her
obligation to resell shares as required by the provisions of the Plan and the
applicable award, and the Company may retain and/or recover all dividends on
such shares which were paid or payable subsequent to the date on which the
prohibited transfer or breach was made or attempted.

     (g)  Additional Award Provisions.  The Board of Directors may, in its sole
          ---------------------------                                          
discretion, include additional provisions in any award granted under the Plan,
including without limitation commitments to pay cash bonuses, make, arrange for
or guarantee loans or transfer other property to recipients upon the grant of
awards, or such other provisions as shall be determined by the Board of
Directors.

14.  General Restrictions.
     -------------------- 

     (a)  Investment Representations.  The Company may require any person to 
          --------------------------   
whom an option or award is granted, as a condition of exercising such option or
purchasing the shares subject to the award, to give written assurances in
substance and form satisfactory to the Company to the effect that such person is
acquiring the Common Stock subject to the option or award for his or her own
account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as the Company deems
necessary or appropriate in order to comply with federal and applicable state
securities laws.

     (b)  Compliance With Securities Laws.  Each option and award shall be
          -------------------------------                                 
subject to the requirement that if, at any time, counsel to the Company shall
determine that the listing, registration or qualification of the shares subject
to such option or award upon any securities exchange or under any state or
federal law, or the consent or approval of any governmental or regulatory body,
or that the disclosure of non-public information or the satisfaction of any
other condition is necessary as a condition of, or in connection with, the
issuance or purchase of shares thereunder, such option or award may not be
exercised, in whole or in part, unless such listing, registration,
qualification, consent or approval, or satisfaction of such condition shall have
been effected or obtained on conditions acceptable to the Board of Directors.
Nothing herein shall be deemed to require the Company to apply for or to obtain
such listing, registration or qualification, or to satisfy such condition.

                                      -7-

 
15.  Rights as a Shareholder.
     ----------------------- 

     The holder of an option or recipient of an award shall have no rights as a
shareholder with respect to any shares covered by the option or award
(including, without limitation, any rights to receive dividends or non-cash
distributions with respect to such shares) until the date of issue of a stock
certificate to him or her for such shares.  No adjustment shall be made for
dividends or other rights for which the record date is prior to the date such
stock certificate is issued.

16.  Adjustment Provisions for Recapitalizations and Related Transactions.
     -------------------------------------------------------------------- 

     (a)  General.  If, through or as a result of any merger, consolidation, 
          -------   
sale of all or substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar transaction, (i) the outstanding shares of Common Stock
are increased or decreased or are exchanged for a different number or kind of
shares or other securities of the Company, or (ii) additional shares or new or
different shares or other securities of the Company or other non-cash assets are
distributed with respect to such shares of Common Stock or other securities, an
appropriate and proportionate adjustment shall be made in (x) the maximum number
and kind of shares reserved for issuance under the Plan, (y) the number and kind
of shares or other securities subject to then outstanding options under the
Plan, and (z) the price for each share subject to any then outstanding options
under the Plan or repurchase rights of the Company, without changing the
aggregate purchase price as to which such options remain exercisable, provided
that no adjustment shall be made pursuant to this Section 16 if such adjustment
would cause the Plan to fail to comply with Section 422 of the Code or with Rule
16b-3.

     (b)  Board Authority to Make Adjustments.  Any adjustments under this
          -----------------------------------                             
Section 16 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued under the Plan on
account of any such adjustments.

17.  Merger, Consolidation, Asset Sale, Liquidation, etc.
     --------------------------------------------------- 

     (a)  General.  In the event of a consolidation or merger in which
          -------                                                     
outstanding shares of Common Stock are exchanged for securities, cash or other
property of any other corporation or business entity or in the event of a
liquidation of the Company or sale of all or substantially all of the assets of
the Company, the Board of Directors of the Company, or the board of directors of
any corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions, as to outstanding options and
awards: (i) provide that such options shall be assumed, or equivalent options
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), provided that any such options substituted for Incentive
                    --------                                                
Stock Options shall meet the requirements of Section 424(a) of the Code, (ii)
upon written notice to the optionees, provide that all unexercised options will
terminate immediately prior to the consummation of such transaction unless
exercised by the optionee within a specified period following the date of such
notice, (iii) in the event of a merger under the terms of which holders of the
Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the merger (the "Merger Price"), make or
provide for a cash payment to 

                                      -8-

 
the optionees equal to the difference between (A) the Merger Price times the
number of shares of Common Stock subject to such outstanding options (to the
extent then exercisable at prices not in excess of the Merger Price) and (B) the
aggregate exercise price of all such outstanding options in exchange for the
termination of such options, and (iv) provide that all or any outstanding
options shall become exercisable in full, any restrictions on exercising
outstanding options issued pursuant to the Plan prior to any given date shall
terminate and any restrictions on and rights of the Company to repurchase shares
covered by outstanding awards issued pursuant to the Plan shall terminate.

     (b)  Substitute Options.  The Company may grant options under the Plan in
          ------------------                                                  
substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company, or
one of its subsidiaries, of property or stock of the employing corporation.  The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

18.  No Special Employment Rights.
     ---------------------------- 

     Nothing contained in the Plan or in any option or award shall confer upon
any recipient of an award or optionee any right with respect to the continuation
of his or her employment by the Company or interfere in any way with the right
of the Company at any time to terminate such employment or to increase or
decrease the compensation of the optionee.

19.  Other Employee Benefits.
     ----------------------- 

     Except as to plans which by their terms include such amounts as
compensation, neither the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise nor the value of an award granted to an employee will
constitute compensation with respect to which any other employee benefits of
such employee are determined, including, without limitation, benefits under any
bonus, pension, profit-sharing, life insurance or salary continuation plan,
except as otherwise specifically determined by the Board of Directors.

20.  Amendment of the Plan.
     --------------------- 

     (a)  The Board of directors may at any time, and from time to time, modify
or amend the Plan in any respect, except that if at any time the approval of the
shareholders of the Company is required as to such modification or amendment
under Section 422 of the Code or any successor provision with respect to
Incentive Stock Options or under Rule 16b-3 with respect to options held by or
awards made to Reporting Persons, the Board of Directors may not effect such
modification or amendment without such approval.

     (b)  The termination or any modification or amendment of the Plan shall
not, without the consent of an optionee or recipient of an award, affect his or
her rights under an option or award previously granted to him or her.  With the
consent of the optionee or recipient of the award affected,

                                      -9-

 
the Board of Directors may amend outstanding option agreements or awards in a
manner not inconsistent with the Plan.  The Board of Directors shall have the
right to amend or modify (i) the terms and provisions of the Plan and of any
outstanding Incentive Stock Options granted under the Plan to the extent
necessary to qualify any or all such options for such favorable federal income
tax treatment (including deferral of taxation upon exercise) as may be afforded
incentive stock options under Section 422 of the Code and (ii) the terms and
provisions of the Plan and of any outstanding option or award to the extent
necessary to ensure the qualification of the Plan under Rule 16b-3 or any
successor rule.

21.  Withholding.
     ----------- 

     (a)  The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee or recipient of an award any federal, state or
local taxes of any kind required by law to be withheld with respect to any
shares issued upon exercise of options under the Plan or the purchase of shares
subject to the award.  Subject to the prior approval of the Company, which may
be withheld by the Company in its sole discretion, the optionee or recipient of
an award may elect to satisfy such obligations in whole or in part, (i) by
causing the Company to withhold shares of Common Stock otherwise issuable
pursuant to the exercise of an option or the purchase of shares subject to an
award or (ii) by delivering to the Company shares of Common Stock already owned
by the optionee or award recipient.  The shares so delivered or withheld shall
have a fair market value equal to such withholding obligation.  The fair market
value of the shares used to satisfy such withholding obligation shall be
determined by the Company as of the date that the amount of tax to be withheld
is to be determined.  An optionee or award recipient who has made an election
pursuant to this Section 21(a) may only satisfy his or her withholding
obligation with shares of Common Stock which are not subject to any repurchase,
forfeiture, unfulfilled vesting or other similar requirements.

     (b)  Notwithstanding the foregoing, in the case of a Reporting Person, no
election to use shares for the payment of withholding taxes shall be effective
unless made in compliance with any applicable requirements of Rule 16b-3.

     (c)  If the recipient of an award under the Plan elects, in accordance with
Section 83(b) of the Code, to recognize ordinary income in the year of
acquisition of any shares awarded under the Plan, the Company will require at
the time of such election an additional payment for withholding tax purposes
based on the difference, if any, between the purchase price of such shares and
the fair market value of such shares as of the date immediately preceding the
date of the award.

22.  Cancellation and New Grant of Options. Etc.
     -------------------------------------------

     The Board of Directors shall have the authority to effect, at any time and
from time to time, with the consent of the affected optionees, (i) the
cancellation of any or all outstanding options under the Plan and the grant in
substitution there for of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
cancelled options or (ii) the amendment of the terms of

                                      -10-

 
any and all outstanding options under the Plan to provide an option exercise
price per share which is higher or lower than the then-current exercise price
per share of such outstanding options.

23.  Effective Date and Duration of the Plan.
     --------------------------------------- 

     (a)  Effective Date.  The Plan shall become effective when adopted by the
          --------------                                                      
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's shareholders. If such shareholder approval is not obtained within
twelve months after the date of the Board's adoption of the Plan, no options
previously granted under the Plan shall be deemed to be Incentive Stock Options
and no Incentive Stock Options shall be granted thereafter.  Amendments to the
Plan not requiring shareholder approval shall become effective when adopted by
the Board of Directors; amendments requiring shareholder approval (as provided
in Section 20) shall become effective when adopted by the Board of Directors,
but no Incentive Stock Option issued after the date of such amendment shall
become exercisable (to the extent that such amendment to the Plan was required
to enable the Company to grant such Incentive Stock Option to a particular
optionee) unless and until such amendment shall have been approved by the
Company's shareholders.  If such shareholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any Incentive Stock
Options granted on or after the date of such amendment shall terminate to the
extent that such amendment to the Plan was required to enable the Company to
grant such option to a particular optionee.  Subject to this limitation, options
and awards may be granted under the Plan at any time after the effective date
and before the date fixed for termination of the Plan.

     (b)  Termination.  Unless sooner terminated in accordance with Section 17,
          -----------                                                          
the Plan shall terminate, with respect to Incentive Stock Options, upon the
earlier of (i) the close of business on the day next preceding the tenth
anniversary of the date of its adoption by the Board of Directors, or (ii) the
date on which all shares available for issuance under the Plan shall have been
issued pursuant to the exercise or cancellation of options or the final vesting
of awards granted under the Plan. Unless sooner terminated in accordance with
Section 17, the Plan shall terminate with respect to options which are not
Incentive Stock Options and awards on the date specified in (ii) above.  If the
date of termination is determined under (i) above, then options outstanding on
such date shall continue to have force and effect in accordance with the
provisions of the instruments evidencing such options.

24.  Provision for Foreign Participants.
     ---------------------------------- 

     The Board of Directors may, without amending the Plan, modify awards or
options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters.

     Re:  REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8 to be filed by you
with the Securities and Exchange Commission on or about April 3, 1997 (the
"Registration Statement"), in connection with the registration under the
Securities Act of 1933, as amended, of 495,509 shares of your Common Stock (the
"Shares") reserved for issuance pursuant to the exercise of options under the
Softdesk, Inc. 1992 Stock Option Plan, the Softdesk, Inc. 1993 Director Stock
Option Plan and the Softdesk, Inc. 1993 Equity Incentive Plan (collectively,
the "Plans"). As your legal counsel, we have examined the proceedings taken
and proposed to be taken by you in connection with the proposed issuance, sale
and payment of consideration for the Shares pursuant to the Plans.

     It is our opinion that, when issued and sold in the manner referred to in
the Plans, the Shares will be legally and validly issued, fully paid and
nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement and any amendment thereto.

                                  Very truly yours,
