Item 1.   Description of Securities to be Registered.
          ------------------------------------------ 

          On December 14, 1995, pursuant to a Preferred Shares Rights Agreement
(the "Rights Agreement") between Autodesk, Inc. (the "Company") and Harris Trust
and Savings Bank, as Rights Agent (the "Rights Agent"), the Company's Board of
Directors declared a dividend of one right (a "Right") to purchase one one-
thousandth share of the Company's Series A Participating Preferred Stock
("Series A Preferred") for each outstanding share of Common Stock, $.01 par
value ("Common Shares"), of the Company.  The dividend is payable on January 8,
1996 (the "Record Date") to stockholders of record as of the close of business
on that date.  Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series A Preferred at an exercise price
of $200.00 (the "Purchase Price"), subject to adjustment in the event the
Company declares a dividend on the Common Stock payable in Common Stock,
subdivides the number of outstanding shares of Common Stock into a larger number
of such shares or combines the number of outstanding shares of Common Stock into
a smaller number of such shares, among other circumstances.  In addition, under
certain circumstances described more fully herein, the Rights may become
excercisable for Common Shares having a value equal to two times the Purchase
Price and/or Common Stock of certain acquiring companies having a value equal to
two times the Purchase Price.

     On January 15, 1998, the Company and the Rights Agent entered into
Amendment No. 1 to the Rights Agreement, which altered the definitions of
Affiliate and Associate, respectively, set forth in Section 1(b) of the Rights
Agreement to clarify that the acquisition by or beneficial ownership of any
Person (as defined in the Rights Agreement) of less than 20% of the "Voting
Securities" (as defined in Rule 12b-2 of the General Rules and Regulations under
the Exchange Act) of any "Investment Adviser" (as defined under the Investment
Advisers Act of 1940, as amended (the "Investment Advisers Act")), 

                                      -2-

 
registered under the Investment Advisers Act, shall not, solely by virtue of
ownership of such Voting Securities, cause such Person to be deemed to be an
"Affiliate" or "Associate" of such Investment Adviser nor shall such Investment
Adviser be deemed to be an "Affiliate" or "Associate" of such Person.

     The following summary of the principal terms of the Rights Agreement is a
general description only and is subject to the detailed terms and conditions of
the Rights Agreement.  A copy of the Rights Agreement is attached as Exhibit 1
to this Registration Statement and is incorporated herein by reference;
capitalized terms used but not otherwise defined herein shall have the meanings
ascribed to them in the Rights Agreement.

Certain Anti-takeover Effects
- -----------------------------

     The Rights approved by the Board are designed to protect and maximize the
value of the outstanding equity interests in the Company in the event of an
unsolicited attempt by an acquiror to take over the Company, in a manner or on
terms not approved by the Board of Directors.  Takeover attempts frequently
include coercive tactics to deprive the Company's Board of Directors and its
stockholders of any real opportunity to determine the destiny of the Company.
The Rights have been declared by the Board in order to deter such tactics,
including a gradual accumulation in the open market of a 15% or greater position
to be followed by a merger or a partial or two-tier tender offer that does not
treat all stockholders equally.  These tactics can operate to unfairly pressure
stockholders, force them out of their investment and deprive them of the full
value of their shares.

     The Rights are not intended to prevent a takeover of the Company and will
not do so.  The Rights may be redeemed by the Company at $.01 per Right within
ten days (or on such later date as may be determined by a majority of the Board
of Directors, excluding directors affiliated with an Acquiring Person) after the
accumulation of 15% or more of the Company's shares by a single acquiror or
group. 

                                      -3-

 
Accordingly, the Rights should not interfere with any merger or business
combination approved by the Board of Directors.

     However, the Rights may have the effect of rendering more difficult or
discouraging an acquisition of the Company deemed undesirable by the Board of
Directors.  The Rights may cause substantial dilution to a person or group that
attempts to acquire the Company on terms or in a manner not approved by the
Company's Board of Directors, except pursuant to an offer conditioned upon the
negation, purchase or redemption of the Rights. As a result, while the Rights
may provide the Board with leverage to obtain a higher price from a potential
acquiror, they may also prevent or deter offers not approved by the Board, and
therefore deprive stockholders, without providing them with the opportunity to
vote thereon, of the benefits of offers which may be at a higher price than the
current market price of the Company's Common Stock.  In addition, assuming an
active trading market in the Rights themselves does not develop, stockholders
with lesser financial means might not be able to take full economic advantage of
the Rights.  Further, the implementation of a rights plan may heighten the
susceptibility of the Company to greenmail by stockholders who threaten to
acquire a sufficient equity position to pass the Rights' triggering threshold,
although the Board can respond to any such action by redeeming the Rights at
$0.01 per Right.

     Issuance of the Rights does not in any way weaken the financial strength of
the Company or interfere with its business plans.  The issuance of the Rights
themselves has no dilutive effect, will not affect reported earnings per share,
should not be taxable to the Company or to its shareholders, and will not change
the way in which the Company's shares are presently traded.  The Company's Board
of Directors believes that the Rights represent a sound and reasonable means of
addressing the complex issues of corporate policy created by the current
takeover environment.

                                      -4-

 
Rights Evidenced by Common Share Certificates
- ---------------------------------------------

     The Rights will not be exercisable until the Distribution Date (defined
below).  Prior to the Distribution Date, certificates for the Rights ("Rights
Certificates") will not be sent to shareholders and the Rights will attach to
and trade only together with the Common Shares.  Accordingly, Common Share
certificates outstanding on the Record Date will evidence the Rights related
thereto, and Common Share certificates issued after the Record Date but prior to
the Distribution Date will contain a notation incorporating the Rights Agreement
by reference.  Until the Distribution Date (or earlier redemption or expiration
of the Rights), the surrender or transfer of any certificates for Common Shares,
even without notation or a copy of the Summary of Rights being attached thereto
(but as to certificates representing Common Shares issued after the Record Date,
only if they bear the legend required by the Rights Agreement), will also
constitute the transfer of the Rights associated with the Common Shares
represented by such certificate.

Distribution Date
- -----------------

     The Rights will separate from the Common Shares, Rights Certificates will
be issued and the Rights will become exercisable upon the earlier of:  (i) 10
days (or such later date as may be determined by a majority of the Board of
Directors, excluding directors affiliated with the Acquiring Person, as defined
below (the "Continuing Directors")) following a public announcement that a
person or group of affiliated or associated persons (an "Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding Common Shares, or (ii) 10 days (or such later date as may be
determined by a majority of the Continuing Directors) following the commencement
of, or announcement of an intention to make, a tender offer or exchange offer
the consummation of which 

                                      -5-

 
would result in the beneficial ownership by a person or group of 15% or more of
the outstanding Common Shares. The earlier of such dates is referred to as the
"Distribution Date."

Issuance of Rights Certificates; Expiration of Rights
- -----------------------------------------------------

     As soon as practicable following the Distribution Date, separate Rights
Certificates will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will evidence the Rights from and after the Distribution Date. All Common
Shares issued prior to the Distribution Date will be issued with Rights.  Common
Shares issued after the Distribution Date may be issued with Rights if such
shares are issued (i) upon the conversion of outstanding convertible debentures
or any other convertible securities issued after adoption of the Rights
Agreement or (ii) pursuant to the exercise of stock options or under employee
benefit plans or arrangements unless such issuance would result in (or create a
risk that) such options, plans or arrangements would not qualify for otherwise
available special tax treatment.  Except as otherwise determined by the Board of
Directors, no other Common Shares issued after the Distribution Date will be
issued with Rights.  The Rights will expire on the earliest of (i) December 14,
2005 (the "Final Expiration Date"), (ii) redemption or exchange of the Rights as
described below, or (iii) consummation of an acquisition of the Company
satisfying certain conditions by a person who acquired shares pursuant to a
Permitted Offer as described below.

Initial Exercise of the Rights
- ------------------------------

     Following the Distribution Date, and until one of the further events
described below, holders of the Rights will be entitled to receive, upon
exercise and the payment of $200.00 per Right, one one-thousandth share of the
Series A Preferred, subject to adjustment in the event the Company declares a
dividend on the Common Stock payable in Common Stock, subdivides the number of
outstanding shares 

                                      -6-

 
of Common Stock into a larger number of such shares or combines the number of
outstanding shares of Common Stock into a smaller number of such shares, among
other circumstances. In addition, under certain circumstances described more
fully herein, the Rights may become excercisable for Common Stock having a value
equal to two times the Purchase Price and/or Common Stock of certain acquiring
companies having a value equal to two times the Purchase Price.

Right to Buy Company Common Shares
- ----------------------------------

     Unless the Rights are earlier redeemed, in the event that an Acquiring
Person becomes the beneficial owner of 15% or more of the Company's Common
Shares then outstanding (other than pursuant to a Permitted Offer), then proper
provision will be made so that each holder of a Right which has not theretofore
been exercised (other than Rights beneficially owned by the Acquiring Person,
which will thereafter be void) will thereafter have the right to receive, upon
exercise and payment of the Purchase Price, Common Shares having a value equal
to two times the Purchase Price.  For example, if the market price of Common
Shares on the Shares Acquisition Date was $50.00, a person holding one Right
could purchase 8 Common Shares upon exercise of such Right ($400/50), whereas he
could only purchase 4 Common Shares ($200/50) in the absence of such Rights.
Rights are not exercisable following the occurrence of an event as described
above until such time as the Rights are no longer redeemable by the Company as
set forth below.

     In the event that the Company does not have sufficient Common Shares
available for all Rights to be exercised, or the Board decides that it is
necessary and not contrary to the interests of Rights holders to do so, the
Company may instead substitute cash, assets or other securities for the Common
Shares for which the Rights would have been exercisable under this provision.

                                      -7-

 
Right to Buy Acquiring Company Stock
- ------------------------------------

     Similarly, unless the Rights are earlier redeemed, in the event that, after
the Shares Acquisition Date (as defined below), (i) the Company is acquired in a
merger or other business combination transaction, or (ii) 50% or more of the
Company's consolidated assets or earning power are sold (other than in
transactions in the ordinary course of business) (either of which event is
referred to herein as an "Acquisition"), proper provision must be made so that
each holder of a Right which has not theretofore been exercised (other than
Rights beneficially owned by the Acquiring Person, which will thereafter be
void) will thereafter have the right to receive, upon exercise, shares of common
stock of the acquiring company having a value equal to two times the Purchase
Price (unless the transaction satisfies certain conditions and is consummated
with a person who acquired shares pursuant to a Permitted Offer, in which case
the Rights will expire).  So (assuming no satisfaction of such conditions) if
for example the market price of the acquiror's stock on the date of the
Acquisition were $25.00, a person holding one Right could purchase 16 shares of
the acquiror's Common Stock upon exercise of such Right ($400/25), whereas he
could only purchase 8 shares of acquiror's Common Stock ($200/25) in the absence
of such Rights.

Permitted Offer
- ---------------

     A Permitted Offer means a tender offer for all outstanding Common Shares
that has been determined by a majority of the Continuing Directors to be
adequate and otherwise in the best interests of the Company and its
stockholders.  Where the Board of Directors has determined that a tender offer
constitutes a Permitted Offer, the Rights will not become exercisable to
purchase Common Shares or shares of the acquiring company (as the case may be)
at the discounted price described above.

                                      -8-

 
Exchange Provision
- ------------------

     At any time after the acquisition by an Acquiring Person of 15% or more of
the Company's outstanding Common Shares and prior to the acquisition by such
Acquiring Person of 50% or more of the Company's outstanding Common Shares, the
Board of Directors of the Company may exchange the Rights (other than Rights
owned by the Acquiring Person), in whole or in part, at an exchange ratio of one
Common Share per Right.

Redemption
- ----------

     At any time on or prior to the close of business on the earlier of (i) the
10th day following the acquisition by an Acquiring Person (the "Share
Acquisition Date") or such later date as may be determined by a majority of the
Continuing Directors and publicly announced by the Company, or (ii) the Final
Expiration Date of the Rights, the Company may redeem the Rights in whole, but
not in part, at a price of $.01 per Right.

Adjustments to Prevent Dilution
- -------------------------------

     The Purchase Price payable, the number of Rights, and the number of Series
A Preferred or Common Shares or other securities or property issuable upon
exercise of the Rights are subject to adjustment from time to time in connection
with the dilutive issuances by the Company as set forth in the Rights Agreement.
With certain exceptions, no adjustment in the Purchase Price will be required
until cumulative adjustments require an adjustment of at least 1% in such
Purchase Price.

Cash Paid Instead of Issuing Fractional Shares
- ----------------------------------------------

     No fractional portion less than integral multiples of one Common Share will
be issued upon exercise of a Right and in lieu thereof, an adjustment in cash
will be made based on the market price of the Common Shares on the last trading
date prior to the date of exercise.

                                      -9-

 
No Shareholders' Rights Prior to Exercise
- -----------------------------------------

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company (other than any rights resulting from
such holder's ownership of Common Shares), including, without limitation, the
right to vote or to receive dividends.

Amendment of Rights Agreement
- -----------------------------

     The provisions of the Rights Agreement may be supplemented or amended by
the Board of Directors in any manner prior to the close of business on the
Distribution Date without the approval of Rights holders.  After the
Distribution Date, the provisions of the Rights Agreement may be amended by the
Board in order to cure any ambiguity, defect or inconsistency, to make changes
which do not adversely affect the interests of holders of Rights (excluding the
interests of any Acquiring Person), or to shorten or lengthen any time period
under the Rights Agreement; provided, however, that no amendment to adjust the
time period governing redemption shall be made at such time as the Rights are
not redeemable.

Rights and Preferences of the Series A Preferred
- ------------------------------------------------

     Series A Preferred purchasable upon exercise of the Rights will not be
redeemable.  Each share of Series A Preferred will be entitled to an aggregate
dividend of 1,000 times the dividend declared per Common Share.  In the event of
liquidation, the holders of the Series A Preferred will be entitled to a minimum
preferential liquidation payment equal to the greater of (i) $1,000 per share or
(ii) 1,000 times the per share amount to be distributed to the holders of the
Common Shares.  Each share of Series A Preferred will have 1,000 votes, voting
together with the Common Shares.  In the event of any merger, consolidation or
other transaction in which the Common Shares are changed or exchanged, each
share of Series A Preferred will be entitled to receive 1,000 times the amount
received per Common Share. 

                                      -10-

 
These rights are protected by customary anti-dilution provisions.

     Because of the nature of the dividend, liquidation and voting rights of the
shares of Series A Preferred, the value of the one one-thousandth interest in a
share of Series A Preferred purchasable upon exercise of each Right should
approximate the value of one Common Share.

                                      -11-

                      AMENDMENT NO. 1 TO RIGHTS AGREEMENT
                      -----------------------------------



        THIS AMENDMENT NO. 1 (this "Amendment"), dated as of January 14, 1998,
to the Rights Agreement, dated as of December 14, 1995 (the "Rights Agreement"),
between Autodesk, Inc., a Delaware corporation (the "Company"), and Harris Trust
and Savings Bank, as Rights Agent (the "Rights Agent").

          A.   The Company and the Rights Agent have heretofore executed and
entered into the Rights Agreement.  Pursuant to Section 27 of the Rights
Agreement, the Company and the Rights Agent may from time to time supplement or
amend the Rights Agreement in accordance with the provisions of Section 27
thereof.

          B.   The Board of Directors of the Company has determined that the
amendments to the Rights Agreement set forth below are in the best interests of
the stockholders of the Company.

          In consideration of the foregoing and the mutual agreements set forth
herein, the parties hereto agree as follows:

     1.   Section l(b) of the Rights Agreement is hereby amended and restated in
its entirety to read as follows:

          (b) "Affiliate" and "Associate" shall have the respective meanings
     ascribed to such terms in Rule 12b-2 of the General Rules and Regulations
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
     as in effect on the date of this Agreement; provided, however that the
                                                 --------  -------         
     acquisition by or beneficial ownership of any Person of less than 20% of
     the "Voting Securities" (as defined in Rule 12b-2 of the General Rules and
     Regulations under the Exchange Act) of any "Investment Adviser" (as defined
     under the Investment Advisers Act of 1940, as amended (the "Investment
     Advisers Act")), registered under the Investment Advisers Act, shall not,
     solely by virtue of ownership of such Voting Securities, cause such Person
     to be deemed to be an "Affiliate" or "Associate" of such Investment Adviser
     nor shall such Investment Adviser be deemed to be an "Affiliate" or
     "Associate" of such Person.

     2.   This Amendment shall be governed by and construed in accordance with
the laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with all laws of such State applicable to contracts to
be made and performed entirely within such State.

     3.   This Amendment may be executed in any number of counterparts, each of
which shall be an original, but such counterparts shall together constitute one
and the same instrument.

 
     4.   In all respects not inconsistent with the terms and provisions of this
Amendment, the Rights Agreement is hereby ratified, adopted, approved and
confirmed.  In executing and delivering this Amendment, the Rights Agent shall
be entitled to all the privileges and immunities afforded to the Rights Agent
under the terms and conditions of the Rights Agreement.

     5.   If any term, provision, covenant or restriction of this Amendment is
held by a court of competent jurisdiction or other authority to be invalid, void
or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Amendment, and of the Rights Agreement, shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.
