     This Amendment No. 3 amends and supplements the Registration 
Statement on Form 8-A (the "Form 8-A") of Informix Corporation, a 
Delaware corporation (the "Company"), filed with the Securities and 
Exchange Commission on September 18, 1991, and as subsequently amended 
May 27, 1992 and August 11, 1995.  All capitalized terms not otherwise 
defined herein shall have the meanings ascribed to them in the Form 8-A, 
as amended.

Item 1.     Description of Securities to Be Registered.

     Item 1 is hereby amended to read in its entirety as follows:

     On September 19, 1991, the Company filed a Registration Statement 
on Form 8-A (the "Registration Statement") with the Securities and 
Exchange Commission (the "Commission") for the purpose of registering 
Preferred Share Purchase Rights issuable in accordance with the terms of 
the Preferred Shares Rights Agreement (the "Original Rights Agreement") 
between the Company and The First National Bank of Boston, as rights 
agent.  On May 27, 1992 and August 11, 1995, the Company filed Forms 8-
A/A to reflect the fact that the Company and The First National Bank of 
Boston had amended the Original Rights Agreement, as originally executed 
(the "Prior Rights Agreement").  Pursuant to the Original Rights 
Agreement, as amended through the Prior Rights Agreement, the Company's 
Board of Directors had declared a dividend of one right (the "Right") to 
purchase one-thousandth share of the Company's Series A Participating 
Preferred Stock ("Series A Preferred") for each share of Common Stock, 
$0.01 par value ("Common Shares"), of the Company issued and outstanding 
on November 20, 1991 (the "Record Date"), and one Right for each Common 
Share issued after the Record Date.  Each Right entitled the registered 
holder to purchase from the Company one one-thousandth share of Series A 
Preferred Stock at an exercise price as set forth in the Prior Rights 
Agreement.

     On August 12, 1997, the Company and BankBoston, N.A., as successor 
rights agent, entered into the First Amended and Restated Rights 
Agreement (the "Amended Rights Agreement"), which supersedes the Prior 
Rights Agreement as originally executed.  The terms of the Amended 
Rights Agreement are substantially similar to those of the Prior Rights 
Agreement, except that each Right is now exercisable, following the 
Distribution Date and until the occurrence of certain specified events, 
for one Common Share at an exercise price of $60.00.

     The following summary of the principal terms of the Amended Rights 
Agreement is a general description only and is subject to the detailed 
terms and conditions of the Amended Rights Agreement.  A copy of the 
Amended Rights Agreement is attached as Exhibit 5 to this Registration 
Statement and is incorporated herein by reference.

Rights Evidenced by Common Share Certificates

     The Rights will not be exercisable until the Distribution Date 
(defined below).  Certificates for the Rights ("Rights Certificates") 
will not be sent to stockholders, 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 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, outstanding as of the Record Date, even without 
notation or a copy of the Summary of Rights being attached thereto, 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 20% or more of the outstanding 
Common Shares, or (ii) 10 business 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 would result in beneficial 
ownership by a person or group of 20% 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) July 25, 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 one Common Share upon exercise and the payment of $60.00 per 
Right (the "Purchase Price").  In the event that the Company does not 
have sufficient Common Shares available for all Rights to be exercised, 
or the Board decides that such action is necessary and not contrary to 
the interests of the Rights holders, 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 or as described 
below.

Right to Buy Company Common Shares

     Unless the Rights are earlier redeemed, in the event that an 
Acquiring Person becomes the beneficial owner of 20% 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, Common 
Shares having a value equal to two times the Purchase Price.  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.

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), 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).

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.

Exchange Provision

     At any time after the acquisition by an Acquiring Person of 20% 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.

Adjustments to Prevent Dilution

     The Purchase Price payable, the number of Rights, and the number of 
Common Shares or other securities or property issuable upon exercise of 
the Rights are subject to adjustment from time to time to prevent 
dilution 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.

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 $0.01 per 
Right.

No Stockholders' Rights Prior to Exercise

     Until a Right is exercised, the holder thereof, as such, will have 
no rights as 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 the 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.

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 of shares in the open market of a 20% 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 
unfairly pressure stockholders, squeeze them out of their investment 
without giving them any real choice, 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 $0.01 
per Right within ten days (or such later date as may be determined by a 
majority of the Board of Directors, excluding directors affiliated with 
the acquiror) after the accumulation of 20% or more of the Company's 
shares by a single acquiror or group.  Accordingly, the Rights should 
not interfere with any merger or business combination approved by the 
Board of Directors.

     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 has no dilutive effect, will not affect reported 
earnings per share, should not be taxable to the Company or to its 
stockholders, 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.

     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.
