                                    ILLUSTRA

   
                                                                February 8, 1996
    

Dear Stockholder:

   
    A Special Meeting of Stockholders of Illustra Information Technologies, Inc.
("Illustra") will be held on Friday, February 16, 1996 at 9:00 a.m., local time,
at Illustra's offices located at 1111 Broadway, Suite 2000, Oakland, California.
    

   
    At  this Special Meeting,  you will be  asked to consider  and vote upon the
approval and adoption of  an Agreement and Plan  of Reorganization, dated as  of
December 20, 1995 (the "Merger Agreement"), among Illustra, Informix Corporation
("Informix")  and its wholly-owned subsidiary,  Informix Delaware, Inc. ("Merger
Sub"), providing for the merger of  Illustra with Merger Sub (the "Merger"),  as
described  in  the  Notice of  Special  Meeting  of Stockholders  mailed  to the
stockholders  of   Illustra   on  January   27,   1996  and   the   accompanying
Prospectus/Proxy Statement.
    

    As  a result of the Merger, all  outstanding shares of Illustra Common Stock
and Illustra Preferred Stock  will be converted into  shares of Informix  Common
Stock  and all outstanding options and warrants to acquire Illustra Common Stock
or Illustra Preferred Stock will become options and warrants to acquire Informix
Common Stock. The number of shares of Informix Common Stock to be issued in  the
Merger  in  exchange for  the outstanding  shares of  Illustra Common  Stock and
Preferred Stock will depend upon the  capitalization of Illustra at the time  of
the Merger and will not exceed 15,000,000 shares. Upon completion of the Merger,
Illustra will be a wholly-owned subsidiary of Informix.

    Illustra's  Board of Directors has unanimously approved the Merger Agreement
and the transactions contemplated thereby and has determined that the Merger  is
fair  and in the best interests of  Illustra and its stockholders. After careful
consideration, the Board of Directors unanimously recommends a vote in favor  of
approval  and adoption of  the Merger Agreement.  If the Merger  is approved and
consummated, you  will receive  detailed  information on  how to  transmit  your
Illustra  share  certificates to  obtain your  shares  of Informix  Common Stock
representing  the  Merger  consideration.   Please  read  the   Prospectus/Proxy
Statement prior to voting.

    TO ENSURE YOUR REPRESENTATION AT THE MEETING, PLEASE COMPLETE, SIGN AND DATE
THE  ACCOMPANYING PROXY CARD AND RETURN IT IN THE ENCLOSED PREPAID ENVELOPE. You
may revoke your proxy at  any time before it has  been voted, and if you  attend
the  meeting you may  vote in person  even if you  have previously returned your
proxy card. Your prompt cooperation will be greatly appreciated.

                                          Sincerely,

   
                                          /s/ Richard H. Williams
    

                                          Richard H. Williams
                                          PRESIDENT AND CHIEF EXECUTIVE OFFICER

                           PROSPECTUS/PROXY STATEMENT
                               15,000,000 SHARES
                             INFORMIX COMMON STOCK
    

   
    This  Prospectus/Proxy  Statement  constitutes  the  Prospectus  of Informix
Corporation,  a  Delaware  corporation  ("Informix"),  with  respect  to  up  to
15,000,000 shares of its Common Stock, $.01 par value ("Informix Common Stock"),
to  be issued in connection with the  proposed merger (the "Merger") of Informix
Delaware, Inc., a Delaware corporation and a wholly-owned subsidiary of Informix
("Merger Sub"),  with  and  into  Illustra  Information  Technologies,  Inc.,  a
Delaware  corporation  ("Illustra"),  pursuant to  the  terms set  forth  in the
Agreement and Plan of Reorganization, dated as of December 20, 1995 (the "Merger
Agreement"), among  Informix,  Merger Sub  and  Illustra. The  Common  Stock  of
Illustra  is herein  referred to  as "Illustra Common  Stock," and  the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock of  Illustra are  collectively herein referred  to as  "Illustra
Preferred  Stock." As a result of the Merger, all outstanding shares of Illustra
Common Stock  and  Illustra  Preferred Stock  (collectively,  "Illustra  Capital
Stock")  will be converted into a number of shares of Informix Common Stock, all
outstanding options or warrants to acquire shares of Illustra Common Stock  will
become  options or  warrants to  acquire a number  of shares  of Informix Common
Stock, and  all outstanding  warrants to  acquire shares  of Illustra  Preferred
Stock  will become  warrants to  acquire a number  of shares  of Informix Common
Stock. The number of shares of Informix Common Stock to be issued for each share
of  Illustra  Common  Stock  exchanged  in  the  Merger  will  depend  upon  the
capitalization  of Illustra at the Effective Time (defined herein). Assuming all
shares of Illustra Preferred Stock are converted into shares of Illustra  Common
Stock  prior to the Effective Time, and further assuming that the capitalization
of Illustra  at  the  Effective  Time  is  in  all  respects  identical  to  the
capitalization  of  Illustra  at  January  2, 1996  (although  there  can  be no
assurance as to the foregoing), each share of Illustra Common Stock exchanged in
the Merger will be converted into the right to receive approximately 0.77184  of
a  share  of Informix  Common Stock.  See  "Approval of  the Merger  and Related
Transactions -- Manner and Basis of  Converting Shares." In connection with  the
Merger, 10% of the shares of Informix Common Stock otherwise issuable to holders
of  Illustra Capital Stock by virtue of the Merger (the "Escrow Shares") will be
placed into escrow and held as security  for losses incurred by Informix in  the
event  of  certain breaches  by Illustra  of  the covenants,  representations or
warranties contained in the  Merger Agreement. See "Approval  of the Merger  and
Related  Transactions -- Escrow Fund." Holders  of Illustra Capital Stock who do
not vote  in  favor  of the  Merger  may,  under certain  circumstances  and  by
following  prescribed statutory procedures,  receive cash for  their shares. See
"Approval of  the  Merger  and  Related Transactions  --  Appraisal  Rights  and
Dissenters' Rights."
    

   
    This  Prospectus/Proxy  Statement also  constitutes  the Proxy  Statement of
Illustra with  respect  to  the  Special Meeting  of  Stockholders  of  Illustra
scheduled to be held on February 16, 1996 (the "Illustra Meeting").
    

   
    This Prospectus/Proxy Statement and the accompanying form of proxy are first
being mailed to the stockholders of Illustra on or about February 8, 1996.
    

    SEE  "RISK  FACTORS"  AT PAGE  14  FOR  CERTAIN INFORMATION  THAT  SHOULD BE

THE MERGER

    TERMS  OF THE MERGER.   At the  Effective Time (as  defined below), Illustra
will become a wholly-owned subsidiary  of Informix. Informix intends to  combine
the  operations of  the two  corporations as  soon as  practicable following the
closing of the Merger. As a result  of the Merger, the maximum number of  shares
of  Informix Common Stock  to be issued  (including Informix Common  Stock to be

                                       2
<PAGE>
   
reserved for issuance upon exercise of any of Illustra's options and warrants to
be assumed  by Informix)  in exchange  for the  acquisition by  Informix of  all
outstanding Illustra Capital Stock and all unexpired and unexercised options and
warrants  to acquire  Illustra Capital Stock  will be  15,000,000. No adjustment
will be made  in the number  of shares of  Informix Common Stock  issued in  the
Merger  as a result of  any cash proceeds received by  Illustra from the date of
execution of the Merger Agreement to the Effective Time pursuant to the exercise
of options or warrants to acquire Illustra Capital Stock.
    

    Subject to  the terms  and conditions  of the  Merger Agreement,  as of  the
Effective  Time, by virtue of  the Merger and without any  action on the part of
Merger Sub, Illustra or the holder of any shares of Illustra Capital Stock,  the
following will occur:

    CONVERSION  OF ILLUSTRA COMMON  STOCK.  Each share  of Illustra Common Stock
issued and outstanding immediately prior to  the Effective Time (other than  any
shares held by a holder who has exercised and perfected appraisal or dissenters'
rights  for such shares, as  the case may be,  in accordance with the applicable
provisions  of  the  Delaware  General  Corporation  Law  (the  "DGCL")  or  the
California  General Corporation  Law (the "CGCL")  and who has  not withdrawn or
lost such rights ("Dissenting Shares")) will be canceled and extinguished and be
converted automatically  into the  right to  receive that  number of  shares  of
Informix  Common Stock  equal to the  Common Exchange Ratio  (as defined below),
upon surrender of  the certificate  representing such share  of Illustra  Common
Stock  in the  manner provided  in a letter  of transmittal  to be  sent to each
record holder of Illustra Capital Stock promptly following the Effective Time (a
"Letter of  Transmittal"),  including,  with  respect to  each  whole  share  of
Informix  Common Stock to be received, the  right to receive one preferred share
purchase right  (a  "Right") under  Informix's  Amended and  Restated  Preferred
Shares  Rights Agreement dated as of September 12, 1991 and amended and restated
as of May 15,  1992 and July 25,  1995, and in any  case, subject to the  escrow
provisions  of  the  Merger  Agreement  described  under  the  section  entitled
"Approval of the Merger and Related Transactions -- Escrow Fund" below.

   
    The "Common Exchange Ratio" will depend on the capitalization of Illustra at
the Effective Time.  Assuming that all  shares of Illustra  Preferred Stock  are
converted  to shares of Illustra  Common Stock prior to  the Effective Time, and
further assuming that the capitalization of Illustra at the Effective Time is in
all other respects  identical to the  capitalization of Illustra  at January  2,
1996  (although  there can  be no  assurance  as to  the foregoing),  the Common
Exchange Ratio will  be 0.77184 of  a share  of Informix Common  Stock for  each
share  of  Illustra  Common  Stock.  For  a  more  detailed  discussion  of  the
calculation of  the Common  Exchange  Ratio, see  "Approval  of the  Merger  and
Related Transactions -- Manner and Basis of Converting Shares" below. The Common
Exchange  Ratio and the exchange ratios relating to shares of Illustra Preferred
Stock will be adjusted to reflect fully  the effect of any stock split,  reverse
split,  stock  dividend (including  any dividend  or distribution  of securities
convertible  into   Informix   Common   Stock  or   Illustra   Capital   Stock),
reorganization,  recapitalization or other like  change with respect to Informix
Common Stock or Illustra Capital Stock occurring after the date of execution  of
the Merger Agreement and prior to the Effective Time.
    

    CONVERSION  OF ILLUSTRA PREFERRED  STOCK.  Each share  of Series A Preferred
Stock of Illustra ("Series A Preferred"),  Series B Preferred Stock of  Illustra
("Series  B  Preferred"),  Series  C  Preferred  Stock  of  Illustra  ("Series C
Preferred") and  Series D  Preferred Stock  of Illustra  ("Series D  Preferred")
issued  and outstanding immediately prior to  the Effective Time (other than any
shares of Illustra Preferred  Stock that are converted  into shares of  Illustra
Common  Stock immediately prior to the Effective Time and any Dissenting Shares)
will be canceled and extinguished and be converted automatically into the  right
to  receive 0.03728, 0.05825, 0.08738 and 0.11650  of a share of Informix Common
Stock, respectively, upon surrender of  the certificate representing such  share
of Illustra Preferred Stock in the manner provided in the Letter of Transmittal,
including,  with respect  to each  whole share  of Informix  Common Stock  to be
received, one Right, and in  any case, subject to  the escrow provisions of  the
Merger  Agreement described under  the section entitled  "Approval of the Merger
and Related Transactions -- Escrow Fund" below.

                                       3
<PAGE>
    Holders of Illustra Preferred Stock should note that the number of shares of
Informix Common Stock which they will be entitled to receive in respect of  each
share  of Illustra Preferred Stock held by them  by virtue of the Merger will be
significantly greater if such shares  of Illustra Preferred Stock are  converted
into  shares of Illustra Common Stock prior to the Effective Time. The holder of
all of Illustra's Series C Preferred Stock has already executed and delivered to
Illustra a notice indicating its irrevocable  election to convert its shares  of
Series  C Preferred  Stock into Illustra  Common Stock immediately  prior to the
Effective Time. Holders of a sufficient  number of shares of Illustra  Preferred
Stock  to  cause  the  automatic  conversion of  all  other  shares  of Illustra
Preferred Stock into shares  of Illustra Common Stock  have entered into  Voting
Agreements  (collectively, the "Voting Agreements") with Informix, which provide
for their irrevocable election to vote  in favor of such conversion  immediately
prior   to  the  Effective  Time.  See  "Approval  of  the  Merger  and  Related
Transactions -- Voting Agreements."

    STOCK OPTIONS.  At the Effective  Time, each outstanding option to  purchase
shares  of Illustra  Common Stock (each  an "Illustra  Option") under Illustra's
1992 Equity Incentive Plan (the "Option Plan"), or otherwise, whether vested  or
unvested,  will be,  in connection  with the  Merger, assumed  by Informix. Each
Illustra Option so assumed by Informix under the Merger Agreement will  continue
to  have, and  be subject  to, the same  terms and  conditions set  forth in the
Option Plan and/or  as provided  in the respective  option agreements  governing
such  Illustra Option immediately  prior to the Effective  Time, except that (i)
such Illustra Option  will be  exercisable for that  number of  whole shares  of
Informix  Common Stock equal to the product  of the number of shares of Illustra
Common  Stock  that  were  issuable  upon  exercise  of  such  Illustra   Option
immediately prior to the Effective Time multiplied by the Common Exchange Ratio,
rounded  down (in the case of Illustra Options granted under the Option Plan) to
the nearest whole number  of shares of  Informix Common Stock  and (ii) the  per
share  exercise  price for  the shares  of Informix  Common Stock  issuable upon
exercise of  such  assumed  Illustra  Option  will  be  equal  to  the  quotient
determined  by dividing the exercise price per share of Illustra Common Stock at
which such Illustra Option  was exercisable immediately  prior to the  Effective
Time  by the Common Exchange Ratio, rounded up  to the nearest whole cent. It is
the intention of  Informix and  Illustra that  the Illustra  Options assumed  by
Informix  qualify following the Effective Time  as incentive stock options under
the Internal Revenue Code of  1986, as amended (the  "Code"), to the extent  the
Illustra  Options qualified as incentive stock  options immediately prior to the
Effective Time.

    In connection with the Merger, the Illustra Common Stock subject to an early
exercise stock purchase agreement  under the Option Plan  will be exchanged  for
Informix  Common Stock at the Common Exchange  Ratio, and the shares of Informix
Common Stock so  received shall continue  to be subject  to the same  repurchase
right in favor of the surviving corporation, which the surviving corporation may
assign  to Informix. The  number of shares  of Informix Common  Stock subject to
repurchase from time to time after the Merger and the repurchase price per share
shall be appropriately adjusted to reflect the exchange of Illustra Common Stock
for Informix Common Stock.

    WARRANTS.   Each warrant  to  purchase shares  of Illustra  Preferred  Stock
outstanding  at  the Effective  Time  will be,  in  connection with  the Merger,
assumed by  Informix. Each  warrant  so assumed  by  Informix under  the  Merger
Agreement  will  continue  to  have,  and be  subject  to,  the  same  terms and
conditions set forth in the warrant agreement governing such warrant immediately
prior to the Effective Time, except  that each such warrant will, following  the
Effective Time, be exercisable only for shares of Informix Common Stock, in such
number,  and at such exercise price as is determined by applying the appropriate
exchange ratio in accordance with the terms of the applicable warrant agreement.

    No fractional  shares  will  be  issued by  Informix  in  the  Merger.  Each
stockholder  of  Illustra  otherwise  entitled  to  a  fractional  share  (after
aggregating all fractional shares of such stockholder) will receive an amount of
cash (rounded  to the  nearest whole  cent) equal  to the  product of  (i)  such

                                       4
<PAGE>
fraction  multiplied by (ii)  the average closing  price of a  share of Informix
Common Stock for the five most recent days that Informix Common Stock has traded
ending on the trading day immediately  prior to the Effective Time, as  reported
on the Nasdaq National Market ("Nasdaq").

   
    EFFECTIVE  TIME OF THE  MERGER.  The  Merger will become  effective upon the
filing of a Certificate of Merger with  the Secretary of State of Delaware  (the
"Effective Time"). Assuming all conditions to the Merger are met or waived prior
thereto,  it is anticipated that the Effective Time will be on or about February
16, 1996.
    

    FORM S-8 REGISTRATION STATEMENT.  No later than ten business days after  the
Effective  Time, Informix will  file a registration statement  on Form S-8 under
the Securities Act covering  the shares of Informix  Common Stock issuable  upon
exercise  of certain Illustra Options to be assumed by Informix at the Effective
Time. See "Approval of the Merger  and Related Transactions -- Manner and  Basis
of Converting Shares -- Stock Options."

   
    STOCK  OWNERSHIP FOLLOWING  THE MERGER.   Based  upon the  capitalization of
Illustra as of the close of business  on January 2, 1996, and assuming that  (i)
all  shares of Illustra Preferred Stock are converted into Illustra Common Stock
prior to the  Effective Time, (ii)  all warrants to  acquire Illustra  Preferred
Stock are exercised prior to the Effective Time, and (iii) no holder of Illustra
Capital  Stock exercises  appraisal or  dissenters' rights  (the "Exchange Ratio
Assumptions"), an  aggregate  of  approximately 12,315,000  shares  of  Informix
Common  Stock will be issued to Illustra stockholders in the Merger and Informix
will assume options exercisable for up to an additional approximately  2,685,000
shares  of Informix Common  Stock. Based upon  the number of  shares of Informix
Common Stock issued and  outstanding as of December  31, 1995, and after  giving
effect  to the issuance  of Informix Common  Stock as described  in the previous
sentence, the former  holders of  Illustra Capital  Stock would  hold, and  have
voting  power with respect to, approximately 8.3% of Informix's total issued and
outstanding shares, and holders  of former Illustra  Options would hold  options
exercisable  for approximately 1.8%  of Informix's total  issued and outstanding
shares (assuming the exercise  of only such options).  The foregoing numbers  of
shares   and  percentages  are   subject  to  change  in   the  event  that  the
capitalization of Illustra changes  subsequent to January 2,  1996 and prior  to
the   Effective  Time,  and  there  can  be   no  assurance  as  to  the  actual
capitalization of Illustra at the Effective Time.
    

    ESCROW FUND.  In connection with the  Merger, at the Effective Time, 10%  of
the  shares of  Informix Common  Stock issuable  to holders  of Illustra Capital
Stock by virtue of the  Merger (the "Escrow Shares")  will be registered in  the
name  of and  deposited with  First Trust  of California,  as escrow  agent (the
"Escrow Agent"), such deposit to constitute the escrow fund (the "Escrow Fund").
The Escrow Shares  shall be contributed  to the  Escrow Fund on  behalf of  each
holder  of Illustra  Capital Stock  at the Effective  Time in  proportion to the
aggregate number of shares of Informix Common Stock such holder would  otherwise
receive by virtue of the Merger (10% of the shares otherwise deliverable to each
holder  of  Illustra Capital  Stock).  No portion  of  the Escrow  Fund  will be
contributed in respect of any options or warrants to acquire shares of  Illustra
Capital  Stock. The  Escrow Shares will  be held  in escrow as  security for any
losses that Informix  incurs or  reasonably anticipates incurring  by reason  of
breaches  by Illustra of  covenants, representations or  warranties contained in
the Merger Agreement. Illustra stockholders will have voting rights with respect
to the Escrow Shares while in escrow. Except in limited circumstances,  Informix
may  not receive  any shares  from the  Escrow Fund  unless and  until losses in
excess of $500,000 have been suffered,  in which case Informix may recover  from
the  Escrow Fund an amount of  Escrow Shares with a value  equal to the total of
its losses in excess of $500,000.  For the purpose of compensating Informix  for
its  losses, the  Escrow Shares shall  be valued  at the average  of the closing
prices of Informix Common Stock for the five consecutive trading days ending two
days prior  to  the  closing  date  of the  Merger.  Subject  to  resolution  of
unsatisfied claims of Informix, the Escrow Fund shall terminate upon the earlier
of  (i) twelve  months following  the closing  date of  the Merger  and (ii) the
issuance of Informix's audited financial  statements for the fiscal year  ending
December 31, 1996.

IN ARTICLE VII OF THE MERGER AGREEMENT. SEE ARTICLE VII OF THE MERGER  AGREEMENT
FOR  A MORE  DETAILED EXPLANATION  OF THE  ESCROW FUND  AND RIGHTS  WITH RESPECT
THERETO.

   
    MARKET PRICE DATA.   Informix Common Stock has  been traded on Nasdaq  under
the symbol "IFMX" since Informix's initial public offering in September 1986. On

Illustra that  they  had signed  the  Merger  Agreement, the  closing  price  of
Informix  Common Stock as reported on Nasdaq was $25.75 per share. Following the

Effective Time of the Merger. See "Risk Factors" and "Informix -- Informix Stock
Information."
    

    No established trading market exists for Illustra Capital Stock.

   
    REASONS FOR THE MERGER.  In the  discussions that led to the signing of  the
Merger  Agreement, Informix and  Illustra each identified  a number of potential
benefits resulting from the  Merger. Informix believes  that the integration  of
Illustra's   object-relational  database  technology   will  give  the  combined
companies a significant time-to-market advantage over other database vendors  in
providing   support  for   complex  data,  such   as  audio,   video,  text  and
three-dimensional graphics,  in a  high  performance scalable  environment.  The
Illustra  Board identified a number of  potential benefits which would accrue to
Illustra and its  stockholders as a  result of the  Merger, including  potential
functionality  and time-to-market  advantages resulting from  the combination of
the two companies'  technologies, the  potential benefit to  Illustra of  direct
access  to  Informix's customer  base,  the increased  marketing,  financial and
personnel resources to be made available to  Illustra as a result of the  Merger
and the liquidity that will be available to holders of Illustra Capital Stock as
a  result of the Merger. See "Approval of the Merger and Related Transactions --
Informix's Reasons for the Merger" and "-- Illustra's Reasons for the Merger."
    

    RECOMMENDATION OF ILLUSTRA BOARD  OF DIRECTORS.  The  Board of Directors  of
Illustra  (the "Illustra Board")  has unanimously approved  the Merger Agreement
and believes that the Merger is fair to, and in the best interests of,  Illustra
and  its stockholders. See  "Approval of the Merger  and Related Transactions --
Material Contacts."

    The Illustra Board did  not seek a fairness  opinion in connection with  the
Merger.  Rather, the Board relied on its own financial expertise to examine from
a  financial  point  of  view  the  fairness  of  the  Merger  and  the   Merger
consideration  to  be received  by Illustra's  stockholders  in the  Merger. See
"Approval of the Merger and Related  Transactions -- Illustra's Reasons for  the
Merger" and "-- Material Contacts."

    CONDUCT OF THE COMBINED COMPANIES FOLLOWING THE MERGER.  Informix intends to
combine the operations of Informix and Illustra as soon as practicable following
the  closing of the Merger. See "Approval of the Merger and Related Transactions
- -- Legal Structure of the Merger."

    EXCHANGE OF ILLUSTRA STOCK CERTIFICATES.  At or promptly after the Effective
Time, Informix, acting through The First National Bank of Boston as its exchange
agent (the  "Exchange Agent"),  will  deliver to  each Illustra  stockholder  of
record  a letter of transmittal with instructions to be used by such stockholder
in surrendering certificates which, prior  to the Merger, represented shares  of
Illustra

                                       6
<PAGE>
Capital Stock. CERTIFICATES SHOULD NOT BE SURRENDERED BY THE HOLDERS OF ILLUSTRA
CAPITAL  STOCK UNTIL  SUCH HOLDERS  RECEIVE THE  LETTER OF  TRANSMITTAL FROM THE
EXCHANGE AGENT. At the Effective Time, each then outstanding option to  purchase
Illustra  Common  Stock, whether  vested or  unvested,  and warrant  to purchase
Illustra Preferred Stock will be assumed  by Informix without any action on  the
part  of  the  holder  thereof.  OPTION  AND  WARRANT  AGREEMENTS  NEED  NOT  BE
SURRENDERED. See "Approval of the Merger and Related Transactions -- Manner  and
Basis of Converting Shares."

    CONDITIONS  TO THE  MERGER.   Consummation of the  Merger is  subject to the
satisfaction of  various conditions,  including approval  of the  Merger by  the
requisite  vote of the stockholders of Illustra  and the receipt by Informix and
Illustra of  certain  letters  from  their  respective  independent  accountants
regarding  the ability  of Informix to  account for  the Merger as  a pooling of
interests. See  "Approval  of the  Merger  and Related  Transactions  --  Voting
Agreements."  The ability of Informix to account  for the Merger as a pooling of
interests depends in part on there being no exercise of appraisal or dissenters'
rights under applicable law  as to greater  than a certain  number of shares  of
Illustra Capital Stock. If appraisal or dissenters' rights are exercised as to a
greater  number  of  shares, then  in  the  absence of  a  waiver  from Informix
regarding the failure to meet that condition, the Merger would not close.

    Consummation of  the Merger  is  also subject  to  the satisfaction  of  the
following  conditions: the Registration Statement filed with the SEC relating to
the issuance of shares  of Informix Common Stock  in connection with the  Merger
shall be effective and such shares shall be authorized for listing on Nasdaq; no
injunction, court order, or other legal restraint preventing consummation of the
Merger  shall be in effect; Informix and Illustra shall have received from their
respective  independent   accountants  letters   reaffirming  the   accountants'
concurrence with management that the Merger may be accounted for as a pooling of
interests;  and Informix  and Illustra shall  have received  opinions from their
respective legal  counsel  to the  effect  that the  Merger  will qualify  as  a
"reorganization"  within the meaning of the  Internal Revenue Code. In addition,
the obligations  of  Illustra  to  consummate the  Merger  are  subject  to  the
following  conditions,  unless  waived  by  Illustra:  the  representations  and
warranties of Informix and Merger Sub contained in the Merger Agreement shall be
accurate except  where  any  breach  or  breaches did  not  have  or  would  not
reasonably  be expected to have a  material adverse effect on Informix; Informix
and Merger  Sub shall  have performed  in all  material respects  the  covenants
required  by  the Merger  Agreement; and  Illustra shall  have received  a legal
opinion from counsel to  Informix. In addition, the  obligations of Informix  to
consummate  the Merger are subject to the following conditions, unless waived by
Informix: the representations and warranties of Illustra contained in the Merger
Agreement shall be accurate except where any breach or breaches did not have  or
would  not reasonably be expected to have  a material adverse effect on Illustra
or Informix;  Illustra  shall  have  performed  in  all  material  respects  the
covenants  required by the Merger Agreement;  and Informix shall have received a
legal opinion from counsel to Illustra. See "Approval of the Merger and  Related
Transactions -- Conditions to the Merger."

   
    VOTING  AGREEMENTS.    Each  of  Accel  IV  L.P.  and  affiliated  entities,
Morgenthaler Venture Partners III, Oak Investment Partners IV and an  affiliated
entity,  Bruce Golden, Paula B. Hawthorn, Harvey C. Jones, Stephen G. Maysonave,
Michael R. Stonebraker,  Michael C. Ubell  and Richard H.  Williams (who own  an
aggregate  of 2,537,300 shares of Illustra  Common Stock and 7,483,503 shares of
Illustra  Preferred   Stock   representing  approximately   58.7%   and   66.4%,
respectively,  of the votes entitled to be cast by holders of shares of Illustra
Common Stock and Illustra Preferred Stock  issued and outstanding as of  January
2,  1996)  has  entered  into  a  Voting  Agreement  (collectively,  the "Voting
Agreements") with Informix. Each of  the foregoing individuals and entities  has
been  identified by  Illustra as  an "affiliate"  (as that  term is  defined for
purposes of Rule 145 promulgated under the Securities Act) of Illustra. Pursuant
to the Voting Agreements, which are irrevocable, each of the foregoing  Illustra
stockholders  has agreed to vote in favor of approval and adoption of the Merger
Agreement and approval  of the Merger.  The vote in  accordance with the  Voting
Agreements of the
    

                                       7
<PAGE>
shares  of Illustra  Common Stock  and Illustra  Preferred Stock  subject to the
Voting Agreements  will be  adequate to  approve the  Merger Agreement  and  the
Merger  by  Illustra  stockholders.  See "Approval  of  the  Merger  and Related
Transactions -- Voting Agreements."

    TERMINATION; FEES; EXPENSES.  The  Merger Agreement may be terminated  under
certain  circumstances, including, without limitation, by mutual written consent
of Informix and Illustra and by either  Informix or Illustra if the other  party
commits  certain breaches of any  representation, warranty or covenant contained
in the Merger Agreement or if the Merger is not consummated on or before May 15,
1996.

    If the Merger  Agreement is terminated  by Informix as  a result of  certain
breaches of the Merger Agreement on the part of Illustra, other than as a result
of  a knowing  or willful  breach by  Illustra, then,  within two  business days
following such termination by Informix, Illustra  has agreed to pay to  Informix
the  sum of $12 million as liquidated damages for the breach giving rise to such
termination. Nothing in the Merger  Agreement, however, limits the liability  of
Illustra for any knowing or willful breaches of the Merger Agreement on the part
of Illustra.

    If  the Merger Agreement  is terminated by  Illustra as a  result of certain
breaches of the Merger Agreement on the part of Informix, other than as a result
of a  knowing or  willful breach  by Informix,  then, within  two business  days
following  such termination by Illustra, Informix  has agreed to pay to Illustra
the sum of $12 million as liquidated damages for the breach giving rise to  such
termination.  Nothing in the Merger Agreement,  however, limits the liability of
Informix for any knowing or willful breaches of the Merger Agreement on the part
of Informix.

    CERTAIN FEDERAL  INCOME  TAX CONSIDERATIONS.    The Merger  is  intended  to
qualify  as a reorganization under Section 368(a)  of the Code, in which case no
gain or loss should generally be recognized by the holders of shares of Illustra
Capital Stock on  the exchange  of their shares  of Illustra  Capital Stock  for
shares  of Informix Common Stock. Receipt of  an opinion from each company's tax
counsel that the Merger will constitute a reorganization under Section 368(a) is
a  condition  to  the  Merger,  which  is  nonwaivable.  HOWEVER,  ALL  ILLUSTRA
STOCKHOLDERS  ARE URGED TO CONSULT THEIR OWN  TAX ADVISORS. See "Approval of the
Merger and Related Transactions -- Certain Federal Income Tax Considerations."

    ACCOUNTING TREATMENT.   The Merger is  intended to qualify  as a pooling  of
interests for financial reporting purposes in accordance with generally accepted
accounting principles. Consummation of the Merger is conditioned upon receipt at
the closing of the Merger by Informix and Illustra of letters from Ernst & Young
LLP,  Informix's  independent auditors,  and KPMG  Peat Marwick  LLP, Illustra's
independent  auditors,  reaffirming  those  firms'  concurrence  with   Informix
management's  and  Illustra management's  conclusions,  respectively, as  to the
appropriateness  of  pooling-of-interests  accounting   for  the  Merger   under
Accounting  Principles Board Opinion  No. 16, if  consummated in accordance with
the Merger Agreement. See  "Approval of the Merger  and Related Transactions  --
Accounting Treatment."

   
    AFFILIATE  AGREEMENTS.  The  persons identified by  Illustra as "affiliates"
(as that  term  is  defined for  purposes  of  Rule 145  promulgated  under  the
Securities  Act)  of Illustra  have entered  into agreements  restricting sales,
dispositions or other transactions reducing their risk of investment in  respect
of the shares of Illustra Capital Stock held by them prior to the Merger and the
shares  of Informix Common Stock received by them in the Merger, subject to a de
minimis exception, so as to comply  with the requirements of applicable  federal
securities  and tax laws and to help ensure that the Merger will be treated as a
pooling of  interests  for  accounting and  financial  reporting  purposes.  The
persons  identified  by Informix  as affiliates  of  Informix have  entered into
agreements with respect to Informix Common Stock  held by them in order to  help
ensure  that the Merger will be treated as a pooling of interests for accounting
and financial  reporting  purposes. See  "Approval  of the  Merger  and  Related
Transactions -- Conditions to the Merger" and "-- Affiliate Agreements."
    

    APPRAISAL  AND DISSENTERS' RIGHTS.  Stockholders of Illustra who do not vote
in favor  of  the Merger  may,  under  certain circumstances  and  by  following
procedures prescribed by the DGCL,

                                       8
<PAGE>
   
exercise  appraisal rights and receive cash for their shares of Illustra Capital
Stock. Alternatively,  although  Illustra  is  a  Delaware  corporation  and  is
therefore  subject  to Delaware  law,  the CGCL  provides  that Illustra  may be
subject to  California  law with  respect  to dissenters'  rights.  Accordingly,
pursuant  to Chapter 13 of the CGCL, stockholders of Illustra who do not vote in
favor of the Merger and who comply with the other requirements of the CGCL, will
have a right to demand payment for, and appraisal of the "fair value" of,  their
shares.  Although the dissenting stockholder may  choose to proceed under either
state's  statute,  a  dissenting  stockholder   of  Illustra  must  follow   the
appropriate  procedures under  either Delaware or  California law  or suffer the
termination or waiver of  such rights. See "Approval  of the Merger and  Related
Transactions   --  Appraisal  and  Dissenters'  Rights"  and  "Applicability  of
California Law to Illustra."
    

    REGULATORY MATTERS.  Informix and Illustra  are aware of no governmental  or
regulatory  approvals  required  for  consummation  of  the  Merger,  other than
compliance with the federal  securities laws and  applicable securities laws  of
the  various states.  See "Approval  of the  Merger and  Related Transactions --
Governmental and Regulatory Approvals."

       SELECTED HISTORICAL AND SELECTED PRO FORMA COMBINED FINANCIAL DATA

   
    The following  selected historical  financial  information of  Informix  and
Illustra   has  been  derived  from  their  respective  historical  consolidated
financial statements and  should be  read in conjunction  with the  consolidated
financial statements and the notes thereto included herein. Informix's unaudited
historical  financial statement data as of and for the nine months ended October
1, 1995  and  October 2,  1994  and Illustra's  unaudited  historical  financial
statement  data as of  and for the six  months ended December  31, 1995 and 1994
have been prepared on the same basis as the historical information derived  from
audited  financial statements and,  in the opinion  of Informix's and Illustra's
management, respectively,  contain all  adjustments, consisting  only of  normal
recurring  adjustments,  necessary for  the fair  presentation of  the financial
position and results of operations for such periods. The unaudited Selected  Pro
Forma  Combined Financial Data are derived from the unaudited Pro Forma Combined
Condensed Financial Statements, appearing elsewhere herein, which give effect to
the Merger as a  pooling of interests,  and should be  read in conjunction  with
such  pro forma  statements and  the notes thereto.  For the  pro forma combined
statement of  income data,  Informix's historical  results for  the nine  months
ended  October 1, 1995 and October 2, 1994 and the years ended December 31, 1994
and 1993 have  been combined  with Illustra's  historical results  for the  nine
months  ended September 30, 1995 and 1994,  the twelve months ended December 31,
1994  and  the  period  from  July  31,  1992  (inception)  to  June  30,  1993,
respectively,  to reflect the Merger  as if it had  occurred at the beginning of
the earliest period presented.  Since Illustra's inception  date was during  its
fiscal  year ended June 30, 1993, the  unaudited pro forma combined statement of
income data for  the year ended  December 31,  1992 are the  same as  Informix's
historical results for such period. No cash dividends have been declared or paid
on Informix Common Stock or Illustra Common or Preferred Stock.
    

    The pro forma information is presented for illustrative purposes only and is
not  necessarily indicative of the operating  results or financial position that
would have occurred if the  Merger had been consummated  as of the beginning  of
the  earliest  period  presented,  nor  necessarily  indicative  of  the  future
operating results or financial position of the combined companies.

(1)  In 1991,  Informix was  selected to  provide the  database component  of  a
     decision-support  system for the Army National  Guard and Army Reserves. In
     1992, Informix received $26.8 million for license fees and support as  part
     of  this Reserve Component  Automation System (RCAS)  contract and recorded
     $21.8 million as  license revenue  and incurred $3.2  million in  operating
     expenses  in 1992. The  remaining $5.0 million of  service revenue is being
     recognized over the support period.

(1) Informix and Illustra estimate that they will incur Merger-related expenses,
    consisting  primarily  of  transaction costs  for  investment  bankers fees,
    attorneys, accountants,  financial printing  and other  related charges,  of
    approximately  $6.0 million. This  estimate is preliminary  and is therefore
    subject to change. These nonrecurring expenses will be charged to operations
    in the fiscal  quarter in  which the Merger  is consummated.  The Pro  Forma
    Combined  Condensed Balance Sheet  gives effect to such  expenses as if they
    had been  incurred  as  of October  1,  1995,  but the  Pro  Forma  Combined
    Condensed Statements of Income do not give effect to such expenses.

                           COMPARATIVE PER SHARE DATA

   
    The following tables set forth certain historical per share data of Informix
and Illustra and combined per share data  on an unaudited pro forma basis  after
giving  effect  to  the  Merger on  a  pooling-of-interests  basis  assuming the
issuance of 0.82685  of a share  of Informix Common  Stock for each  outstanding
share  of Illustra Common Stock  and the issuance of  174,557 shares of Informix
Common Stock in satisfaction of certain rights retained by the former holders of
Illustra's Series C Preferred Stock upon conversion of Series C Preferred  Stock
to  Illustra Common Stock. The exchange ratio above assumes that the transaction
was consummated on  October 1,  1995. The actual  number of  shares of  Informix
Common  Stock to be exchanged  for all of the  outstanding Illustra Common Stock
will be determined at the Effective Time based on the capitalization of Illustra
at the Effective Time. The following data should be read in conjunction with the
Selected Historical Financial  Data, the Selected  Pro Forma Combined  Financial
Data,  the Pro  Forma Combined Condensed  Financial Statements  and the separate
historical financial  statements of  Informix  and Illustra  included  elsewhere
herein.  The unaudited  pro forma  combined per  share data  are not necessarily
indicative of the operating results that would have been achieved had the Merger
been consummated as of the beginning of the earliest period presented and should
not be construed as representative of future operations.

(1) Per share  information applicable  to prior  periods for  Informix has  been
    restated  to reflect a  two-for-one stock split  (effected in the  form of a
    stock dividend) which was effective on June 26, 1995.

(2) The  historical  book  value  per  share  is  computed  by  dividing   total
    stockholders'  equity by the number of shares of common stock outstanding at
    the end of the period and,  with respect to Illustra, assumes conversion  of
    all  outstanding Illustra Preferred Stock into  Illustra Common Stock at the
    end of each period.

(3) The pro  forma  combined net  income  per share  is  based on  the  combined
    weighted  average  number of  common  and dilutive  common  stock equivalent
    shares of  Informix  Common Stock  and  Illustra Common  Stock  and  assumes
    conversion   of   all   of   outstanding   Illustra   Preferred   Stock   at

                                       12
<PAGE>
    the beginning of the earliest period presented and further assumes a  Common
    Exchange  Ratio as  of October  1, 1995  of 0.82685  of a  share of Informix
    Common Stock for  each outstanding share  of Illustra Common  Stock and  the
    issuance  of  174,557 shares  of Informix  Common  Stock in  satisfaction of
    certain rights retained by the former holders of Illustra Series C Preferred
    Stock upon conversion of Series C Preferred Stock to Illustra Common  Stock.
    The actual number of shares of Informix Common Stock to be exchanged for all
    of the outstanding Illustra Common Stock will be determined at the Effective
    Time based on the capitalization of Illustra at the Effective Time.

   
(4) Informix and Illustra estimate that they will incur Merger-related expenses,
    consisting  primarily  of  transaction costs  for  investment  bankers fees,
    attorneys, accountants,  financial printing  and other  related charges,  of
    approximately  $6.0 million. This  estimate is preliminary  and is therefore
    subject to change. These nonrecurring expenses will be charged to operations
    in the fiscal  quarter in  which the Merger  is consummated.  The pro  forma
    combined  book value per share gives effect  to such expenses as if they had
    been incurred as of October 1, 1995,  but the pro forma combined net  income
    per share does not give effect to such expenses.
    

(5) The  Illustra  equivalent  pro forma  per  share amounts  are  calculated by
    multiplying the  Informix  pro  forma  combined per  share  amounts  by  the
    exchange  ratio of  0.82685 of  a share  of Informix  Common Stock  for each
    outstanding share of Illustra Common Stock.  The actual number of shares  of
    Informix  Common Stock to  be exchanged for all  of the outstanding Illustra
    Common Stock  will  be  determined  at  the  Effective  Time  based  on  the
    capitalization of Illustra at the Effective Time.

(6) Illustra's date of inception was July 31, 1992.

                                  RISK FACTORS

    The  following  factors should  be  considered carefully  in  evaluating the
proposals to be  voted on at  the Illustra  Meeting and the  acquisition of  the
securities  offered hereby. For periods following  the Merger, references to the
products, business, results  of operations  or financial  condition of  Informix
should  be  considered  to refer  to  Informix and  its  subsidiaries, including
Illustra, unless the context otherwise requires.

    UNCERTAINTIES RELATING TO INTEGRATION OF OPERATIONS.  Informix and  Illustra
have entered into the Merger Agreement with the expectation that the Merger will
result  in beneficial synergies for the combined companies. See "Approval of the
Merger and Related Transactions  -- Informix's Reasons for  the Merger" and  "--
Illustra's  Reasons for the  Merger." Achieving the  anticipated benefits of the
Merger will depend in  part upon whether the  integration of the two  companies'
businesses  is achieved in an efficient,  effective and timely manner, and there
can be no assurance that this will  occur. The combination of the two  companies
will   require,  among  other  things,  the  timely  integration  of  Illustra's
object-relational  database  technology  with  Informix's  relational   database
technology  and integration of their respective sales and marketing and research
and development efforts.  There can  be no  assurance that  integration will  be
accomplished  smoothly,  on  time  or  successfully.  The  difficulties  of such
integration may  be  increased  by  the complexity  of  the  technologies  being
integrated   and   the  necessity   of  coordinating   geographically  separated
organizations. The integration of certain  operations following the Merger  will
require  the dedication of  management resources which  may temporarily distract
attention from the  day-to-day business  of the combined  companies. Failure  to
effectively  accomplish the integration  of the two  companies' operations could
have an  adverse  effect  on  Informix's results  of  operations  and  financial
condition.

   
    POTENTIAL  DILUTIVE EFFECT TO STOCKHOLDERS.   Although the companies believe
that beneficial synergies will result from the Merger, there can be no assurance
that the combining  of the  two companies' businesses,  even if  achieved in  an
efficient,  effective  and timely  manner, will  result  in combined  results of
operations and financial condition superior to what would have been achieved  by
each company independently, or as to the period of time required to achieve such
result. The issuance of Informix Common Stock in connection with the Merger will
have the effect of reducing Informix's net income per share and could reduce the
market  price of Informix Common  Stock unless and until  revenue growth or cost
savings and other  business synergies sufficient  to offset the  effect of  such
issuance  can be achieved. There can be no assurance that such synergies will be
achieved. In addition, there can be  no assurance that stockholders of  Illustra
would  not achieve greater returns  on investment if Illustra  were to remain an
independent company.
    

   
    DEPENDENCE ON ACCEPTANCE  OF OBJECT-RELATIONAL TECHNOLOGY.   The market  for
the object-relational database products of Illustra is new and evolving, and its
growth  depends both upon the growing need to store complex data and the broader
market acceptance of Illustra's object-relational technology as the solution for
this  need.  Because   object-relational  technology  represents   a  shift   in
programming  methodology, it requires a substantial investment in the retraining
of  programmers,  which  can  be  expensive  and  reduce  the  productivity   of
programmers  during the training period. As a  result, there can be no assurance
that  organizations  will  choose  to  make  the  transition  from  conventional
relational  database management systems to object-relational database management
systems, or as to the time frame within which such transition may occur, even if
they believe that they can benefit  from the advantages of an  object-relational
system.  Any  delay in  the  market's acceptance  of  object-relational database
management systems will reduce the anticipated benefits of the Merger and  could
have  an  adverse  effect  on Informix's  results  of  operations  and financial
condition.
    

    NO EFFECT ON EXCHANGE RATIO  OF PRICE OF INFORMIX  COMMON STOCK.  Under  the
terms  of the Merger Agreement,  the shares of Illustra  Common Stock issued and
outstanding at the Effective  Time will be converted  into the right to  receive
shares  of  Informix Common  Stock. The  Merger Agreement  does not  contain any
provisions for adjustment  of the Exchange  Ratio based on  fluctuations in  the
price  of Informix Common Stock. Accordingly,  the value of the consideration to
be received by stockholders of

                                       14
<PAGE>
Illustra upon the Merger will depend on the market price of the Informix  Common
stock at the Effective Time. On December 20, 1995, the date the Merger Agreement
was signed, the closing price of the Informix Common Stock was $25.75. There can
be  no assurance that the market price of the Informix Common Stock on and after
the Effective Time  will not be  lower than  such price. See  "-- Volatility  of
Informix Stock Prices."

   
    FLUCTUATIONS  IN QUARTERLY RESULTS.   Informix's operating  results can vary
substantially from period to period. The timing and amount of Informix's license
revenues are subject to  a number of factors  that make estimation of  operating
results prior to the end of a quarter extremely uncertain. Informix has operated
historically  with little or no  backlog, and, as a  result, license revenues in
any quarter are dependent on contracts entered into or orders booked and shipped
in that quarter. Informix's quarterly operating margins have generally  followed
a  historic pattern, with  second half revenues  and operating margins generally
being higher than those of the preceding first half. Informix believes that this
pattern has been primarily related to customers' capital spending cycles at  the
end  of a calendar year as well  as to Informix's selling efforts, influenced by
annual sales incentive plans, at the end of the calendar year, which is the  end
of  Informix's  fiscal  year. Additionally,  as  is  common in  the  industry, a
disproportionate  amount  of   Informix's  license  revenue   is  derived   from
transactions  that  close in  the last  few weeks  of a  quarter. The  timing of
closing large license agreements also  increases the risk of  quarter-to-quarter
fluctuations  and  the uncertainty  of  estimating quarterly  operating results.
Informix's operating  expenses  are  based on  projected  annual  and  quarterly
revenue  levels, have  been increasing  at rates  approaching the  rate of total
revenue growth and are incurred  approximately ratably throughout each  quarter.
As  a result,  if projected  revenues are not  realized in  the expected period,
Informix's operating results for that period would be adversely affected as  the
operating  expenses are relatively  fixed in the short  term. Failure to achieve
revenue, earnings and  other operating  and financial results  as forecasted  or
anticipated  by brokerage firm analysts or  industry analysts could result in an
immediate and adverse  effect on the  market price of  Informix's Common  Stock.
Further,  Informix may not learn  of, or be able  to confirm, revenue or earning
shortfalls until the end  of each quarter,  which could result  in an even  more
immediate and adverse effect on the trading price of Informix's Common Stock.
    

   
    COSTS OF INTEGRATION; TRANSACTION EXPENSES.  The combined companies' results
of  operations will be adversely affected by Merger-related expenses, consisting
primarily  of  transaction  costs   for  investment  bankers  fees,   attorneys,
accountants,  financial  printing  and  other related  charges  estimated  to be
approximately $6 million. These nonrecurring costs will be charged to operations
in the  fiscal quarter  in which  the Merger  is consummated.  This estimate  is
preliminary and is therefore subject to change.
    

    VOLATILITY OF INFORMIX STOCK PRICES.  The market for Informix's Common Stock
is  highly  volatile. The  trading  price of  Informix's  Common Stock  could be
subject to wide fluctuations  in response to  quarterly variations in  operating
and  financial  results,  announcements  of  technological  innovations  or  new
products by Informix or its competitors, changes in prices of Informix's or  its
competitors'   products  and  services,  changes  in  product  mix,  changes  in
Informix's revenue  and revenue  growth rates  for Informix  as a  whole or  for
individual  geographic areas, business units, products or product categories, as
well as other events or factors. Statements or changes in opinions, ratings,  or
earnings  estimates made by brokerage firms or industry analysts relating to the
market in which Informix does business or relating to Informix specifically have
resulted, and could in the future result, in an immediate and adverse effect  on
the market price of Informix's Common Stock. Statements by financial or industry
analysts regarding the extent of the dilution in Informix's net income per share
resulting from the Merger and the extent to which such analysts expect potential
business  synergies to  offset such  dilution can  be expected  to contribute to
volatility in the market price of Informix Common Stock. In addition, the  stock
market  has from time to time  experienced extreme price and volume fluctuations
which have particularly  affected the market  price for the  securities of  many
high-

                                       15
<PAGE>
technology  companies  and  which often  have  been unrelated  to  the operating
performance of these  companies. These broad  market fluctuations may  adversely
affect the market price of Informix Common Stock.

   
    COMPETITION.   The market  for Informix's software  products and services is
extremely competitive.  The chief  competition faced  by Informix  is  currently
provided  by  Oracle  Corporation,  Sybase, Inc.,  CA  Ingres  (a  subsidiary of
Computer Associates International, Inc.), IBM Corporation, Microsoft Corporation
and Red Brick Systems,  Inc. and suppliers  of third party  tools such as  Gupta
Corporation,  Forte  Software,  Inc.  and  Dynasty  Technologies,  Inc.  Some of
Informix's current  competitors  and  many potential  competitors  have  greater
financial,  technical and marketing resources than  Informix. To the extent that
market acceptance for personal computer  oriented technologies increases at  the
expense  of UNIX or other  non-PC platforms, this could  result in greater price
pressure  on  certain  of  Informix's   database  products  and  services.   The
availability  and  market  acceptance  of  Microsoft  Corporation's  Windows  NT
operating system may increase the  competition faced by the principal  operating
system  platforms on which Informix's products operate and may result in greater
price pressure on certain  of Informix's database  products and services.  Also,
new or enhanced products introduced by existing or future competitors could have
an  adverse effect on  Informix's business, results  of operations and financial
condition. Existing and future competition  or changes in Informix's product  or
services  pricing structure or  product or service offerings  could result in an
immediate reduction in the  prices of Informix's products  or services. If  this
were  to result  in significant  price declines, the  effects of  which were not
offset by any  resulting increases  in sales  volume of  Informix's products  or
services,  Informix's business,  results of  operations and  financial condition
would be  adversely affected.  There  can be  no  assurance that  Informix  will
continue  to compete successfully with its  existing competitors or will be able
to compete successfully with new competitors.
    

    TECHNOLOGICAL CHANGE AND NEW PRODUCTS.   The market for Informix's  products
and  services is characterized  by rapidly changing  technology and frequent new
product introductions.  Informix's  success  will depend  upon  its  ability  to
enhance  its existing  products and  to introduce new  products on  a timely and
cost-effective basis that meet  dynamic customer requirements.  There can be  no
assurance  that  Informix  will  be successful  in  developing  new  products or
enhancing its  existing products  or that  such new  or enhanced  products  will
receive  market acceptance  or be timely  delivered to the  market. Informix has
experienced product delays in the past and may have delays in the future. Delays
in the scheduled availability or a lack of market acceptance of its products  or
failure  to accurately anticipate  customer demand or  meet customer performance
requirements could  have  a  material adverse  effect  on  Informix's  business,
results  of operations and financial condition. In addition, products as complex
as those offered by  Informix may contain undetected  errors or bugs when  first
introduced  or as  new versions  are released. There  can be  no assurance that,
despite testing, new  products or  new versions  of existing  products will  not
contain undetected errors or bugs that will delay the introduction or commercial
acceptance  of such products. Informix's success  also depends on the ability of
its products  to  interoperate  and  perform  well  with  existing  and  future,
industry-standard  leading application software products  intended to be used in
connection with relational database management systems. Failure to meet existing
and future interoperability and performance requirements of certain  independent
vendors  marketing such applications  in a timely  manner could adversely affect
the market for Informix's products. Commercial acceptance of Informix's products
and services could also be adversely affected by critical or negative statements
or reports  by brokerage  firms, industry  and financial  analysts and  industry
periodicals concerning Informix, its products, business or competitors or by the
advertising  or marketing  efforts of competitors,  or other  factors that could
affect consumer perception.

    INTERNATIONAL OPERATIONS.  Over half of Informix's net revenues are  derived
from  its international operations. Informix's  operations and financial results
could  be  significantly  affected  by  factors  associated  with  international
operations  such as changes in foreign currency exchange rates and uncertainties
relative  to  regional  economic  circumstances,  as  well  as  by  other  risks
associated  with  international  activities.  Most  of  Informix's international
revenue and expenses are denominated in

                                       16
<PAGE>
local currencies. Although Informix takes into account changes in exchange rates
over time in its  pricing strategy, Informix's  business, results of  operations
and   financial  condition  could  be   materially  and  adversely  affected  by
fluctuations in foreign currency exchange rates. There can be no assurance  that
Informix will not experience fluctuations in international revenues.

    INTEGRATION  OF ACQUIRED COMPANIES.  Informix has recently completed several
acquisitions including  the database  division of  ASCII Corporation  in  Japan,
Stanford  Technology  Group,  Inc.  in the  United  States  and  distributors in
Germany, Korea and Malaysia. Informix may acquire other distributors, companies,
products or technologies  in the future.  There can be  no assurance that  these
acquisitions and the acquisition of Illustra can be effectively integrated, that
such  acquisitions will not result in  costs or liabilities that could adversely
effect Informix's  results  of  operations  and  financial  condition,  or  that
Informix will obtain the anticipated or desired benefits of such acquisitions.

    KEY  PERSONNEL.    Informix's  success  depends  in  part  on  the continued
contributions of both companies' key  management and technical personnel.  While
key   employees  do  not  generally  enter  into  employment  or  noncompetition
agreements, certain  key  employees  of  Illustra have  entered  into  two  year
non-competition  agreements in connection with the  Merger. See "Approval of the
Merger and Related Transactions --  Non-Competition Agreements". The success  of
Informix  also  depends  on  Informix's  ability  to  attract  and  retain other
qualified technical,  managerial,  sales and  marketing  personnel.  Uncertainty
during  integration of  the two companies'  businesses may  adversely affect the
combined  companies'  ability  to  attract   and  retain  such  personnel.   The
competition for such personnel is intense in the software industry.

    MANAGEMENT  OF GROWTH.   Both Informix  and Illustra  have experienced rapid
growth in recent  years. There can  be no assurance  Informix will maintain  its
recent  rate of  growth. Informix's  future growth  will depend  in part  on the
ability of its officers and key personnel to manage growth successfully  through
the  implementation of appropriate  management systems and  controls. Failure to
effectively implement  or maintain  such systems  and controls  could  adversely
affect Informix's business, results of operations and financial condition.

    LIMITATIONS   ON  PROTECTION   OF  INTELLECTUAL   PROPERTY  AND  PROPRIETARY
RIGHTS.   Both Informix  and Illustra  rely on  a combination  of trade  secret,
copyright  and  trademark  laws  and  contractual  provisions  to  protect their
proprietary rights in their  software products. There can  be no assurance  that
these  protections will be  adequate or that  competitors will not independently
develop technologies that are substantially equivalent or superior to Informix's
technology. In addition,  copyright and trade  secret protection for  Informix's
products  may be unavailable  or unreliable in certain  foreign countries. As of
the date hereof, neither  Informix nor Illustra has  any issued patents. As  the
number  of software  products in  the industry  and software  patents increases,
Informix believes that  software developers may  become increasingly subject  to
infringement  claims. There  can be  no assurance  that a  third party  will not
assert that its  patents or other  proprietary rights are  violated by  products
offered  by  Informix. Any  such  claims, with  or  without merit,  can  be time
consuming and  expensive  to  defend,  and  could  have  an  adverse  effect  on
Informix's business, results of operations and financial condition. Infringement
of  valid third-party patents and propriety  rights could have an adverse effect
on Informix's business, results of operations and financial condition.  Informix
and  Illustra also rely  on "shrink-wrap" break-the-seal  licenses not signed by
the licensee to protect their proprietary rights. "Shrink-wrap" licenses may  be
unenforceable under the laws of certain jurisdictions.

    DEPENDENCE ON THIRD-PARTY PROVIDERS OF TECHNOLOGY.  The products of Informix
and  Illustra  use  certain  products and  technologies  of  various third-party
software developers, including both complete  products offered as extensions  of
the  companies'  product  lines  and  technology  used  in  the  enhancement  of
internally developed products. Such products and technologies are obtained  from
the  third-party providers under  contractual license agreements,  which in some
cases are for limited time periods and in some cases provide that such  licenses
may  be terminated under  certain circumstances. There can  be no assurance that
Informix will  be able  to maintain  adequate relations  with these  third-party
providers,  that these  third-party providers  will commit  adequate development
resources to

                                       17
<PAGE>
maintain these products and technologies or that the license agreements that are
for  limited  time   periods  will   be  renewed  upon   termination.  In   such
circumstances,  Informix's inability to obtain  or develop substitute technology
could adversely affect Informix's business, results of operations and  financial
condition.

    EFFECT  OF ANTITAKEOVER  PROVISIONS OF  DELAWARE LAW  AND INFORMIX'S CHARTER
DOCUMENTS.  Upon consummation of the  Merger, the stockholders of Illustra  will
become stockholders of Informix, a corporation governed by the laws of Delaware.
Informix  is subject to  the provisions of  Section 203 of  the Delaware General
Corporation Law, which  has the effect  of restricting changes  in control of  a
company.  The Board of Directors of Informix is divided into three classes, with
each class standing for election once every three years. In addition, Informix's
Board of Directors has  authority to issue up  to 5,000,000 shares of  preferred
stock and to fix the rights, preferences, privileges and restrictions, including
voting  rights,  of  such shares  without  any  further vote  or  action  by the
stockholders. Informix  also  has  a  Preferred  Shares  Rights  Agreement  that
provides  for  the issuance  of  rights which,  upon  the occurrence  of certain
events, would result in significant dilution to Informix Common Stock held by  a
bidder  for Informix. These  and other provisions of  Delaware law applicable to
Informix and  Informix's charter  documents  may have  the effect  of  delaying,
deterring  or  preventing  changes in  control  or management  of  Informix. See
"Comparison of Capital Stock."

a.m. local time.
    

PURPOSE

    The purpose  of the  Illustra Meeting  is to  approve and  adopt the  Merger
Agreement and approve the Merger.

RECORD DATE AND OUTSTANDING SHARES

   
    Stockholders of record of Illustra Capital Stock at the close of business on
January  2, 1996 (the "Illustra Record Date")  are entitled to notice of, and to
vote at, the Illustra  Meeting. As of  the Illustra Record  Date, there were  85
stockholders  holding an aggregate of approximately 4,322,000 shares of Illustra
Common  Stock  and  38  stockholders  holding  an  aggregate  of   approximately
11,487,000  shares of  Illustra Preferred Stock  representing the  right to cast
approximately  11,276,000   votes.   See   "Illustra   --   Illustra   Principal
Stockholders."
    

   
    On  January 27, 1996, a notice meeting  the requirements of Delaware law was
mailed to all stockholders of record as of the Illustra Record Date.
    

VOTE REQUIRED; QUORUM

    Approval and adoption  of the Merger  Agreement and approval  of the  Merger
requires  the  affirmative  vote  of  the  holders  of  a  majority  of  (i) the
outstanding Illustra Common Stock and  Illustra Preferred Stock voting  together
as  a single  class, and  (ii) the  outstanding Illustra  Preferred Stock voting
separately as a single class, in each case with each share of Illustra Preferred
Stock being entitled to a number of votes equal to the number of whole shares of
Illustra Common Stock into which such  shares of Illustra Preferred Stock  could
be converted on the Illustra Record Date. Each stockholder of record of Illustra
Common Stock on the Illustra Record Date is entitled to cast one vote per share,
exercisable  in person  or by properly  executed proxy, on  each matter properly
submitted for the vote of the stockholders of Illustra at the Illustra Meeting.

    The presence, in person or by properly  executed proxy, of the holders of  a
majority of the outstanding shares of Illustra Capital Stock entitled to vote at
the  Illustra  Meeting and  a  majority of  the  outstanding shares  of Illustra
Preferred  Stock  entitled  to  vote  at  the  Illustra  Meeting  (each  on   an
as-converted  basis) shall constitute a quorum.  Abstentions will be counted for
purposes of determining a  quorum, but will  have the effect  of a vote  against
approval of the matters being voted upon.

   
    Certain  holders of Illustra Common Stock  and Illustra Preferred Stock have
entered into Voting Agreements with Informix, pursuant to which each such holder
has agreed to  vote (i) in  favor of approval  of the Merger  Agreement and  the
Merger  and (ii) against (among  other things) approval of  any proposal made in
opposition to or competition with consummation of the Merger. In addition,  each
such  holder has granted pursuant to the  Voting Agreements, to each director on
the Board  of Directors  of Informix,  an irrevocable  proxy to  vote shares  as
aforesaid.  The shares of Illustra Common Stock subject to the Voting Agreements
represent 58.7%  of the  votes  entitled to  be cast  by  holders of  shares  of
Illustra  Common Stock as  of the Illustra  Record Date. The  shares of Illustra
Preferred Stock subject
    

                                       19
<PAGE>
to the Voting Agreements  represent 66.4% of  the votes entitled  to be cast  by
holders  of shares of Illustra  Preferred Stock as of  the Illustra Record Date.
THE VOTE IN  ACCORDANCE WITH  THE VOTING AGREEMENTS  OF THE  SHARES OF  ILLUSTRA
COMMON  STOCK AND ILLUSTRA PREFERRED STOCK SUBJECT TO THE VOTING AGREEMENTS WILL
BE ADEQUATE TO APPROVE AND ADOPT THE MERGER AGREEMENT AND APPROVE THE MERGER  BY
THE ILLUSTRA STOCKHOLDERS.

VOTING OF PROXIES

    All  shares of  Illustra Capital  Stock that  are entitled  to vote  and are
represented at the  Illustra Meeting either  in person or  by properly  executed
proxies  received prior to  or at the  Illustra Meeting and  not duly and timely
revoked  will  be  voted  at  the  Illustra  Meeting  in  accordance  with   the
instructions  indicated on such proxies. If  no such instructions are indicated,
such proxies will be voted for the approval and adoption of the Merger Agreement
and approval of the Merger.

    If any  other  matters  are  properly presented  for  consideration  at  the
Illustra Meeting (or any adjournments or postponements thereof) including, among
other  things, consideration  of a  motion to  adjourn or  postpone the Illustra
Meeting to another  time and/or  place (including, without  limitation, for  the
purpose  of soliciting  additional proxies), the  persons named  in the enclosed
forms of proxy and voting  thereunder will have the  discretion to vote on  such
matters in accordance with their best judgment.

    Any  proxy given pursuant to this solicitation  may be revoked by the person
giving it at any time before it is  voted. Proxies may be revoked by (i)  filing
with  the Secretary  of Illustra  at or  before the  taking of  the vote  at the
Illustra Meeting, a written notice of  revocation bearing a later date than  the
proxy;  (ii) duly executing a later-dated proxy  relating to the same shares and
delivering it to the Secretary of Illustra, before the taking of the vote at the
Illustra Meeting or (iii)  attending the Illustra Meeting  and voting in  person
(although  attendance  at  the  Illustra  Meeting  will  not  in  and  of itself
constitute a  revocation  of a  proxy).  Any  written notice  of  revocation  or
subsequent  proxy should be sent  so as to be  delivered to Illustra Information
Technologies, Inc.  at 1111  Broadway, Suite  2000, Oakland,  California  94607,
Attention:  Secretary, or hand-delivered  to the Secretary  of Illustra, in each
case at or before the taking of the vote at the Illustra Meeting.

SOLICITATION OF PROXIES; EXPENSES

    The cost  of the  solicitation of  Illustra stockholders  will be  borne  by
Illustra.  Proxies may be solicited by  certain Illustra directors, officers and
employees personally or by telephone, telecopy or other means of  communication.
Such persons will not receive additional compensation, but may be reimbursed for
reasonable out-of-pocket expenses incurred in connection with such solicitation.

APPRAISAL AND DISSENTERS' RIGHTS

    Stockholders  of Illustra who do not vote  in favor of the Merger may, under
certain circumstances and by following  procedures prescribed by Section 262  of
the  DGCL,  exercise  appraisal rights  and  receive  cash for  their  shares of
Illustra  Capital  Stock.  Alternatively,   although  Illustra  is  a   Delaware
corporation  and is  therefore subject to  Delaware law, the  CGCL provides that
Illustra may be subject  to California law with  respect to dissenters'  rights.
Accordingly, pursuant to Chapter 13 of the CGCL, stockholders of Illustra who do
not  vote in favor of the Merger and who comply with Chapter 13 of the CGCL will
have a right to demand payment for, and appraisal of the "fair value" of,  their
shares.  A  dissenting  stockholder  of  Illustra  must  follow  the appropriate
procedures under either Delaware or California law or suffer the termination  or
waiver  of such rights. See "Approval of  the Merger and Related Transactions --
Appraisal and  Dissenters'  Rights"  and "Applicability  of  California  Law  to
Illustra."

                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS

    THE   FOLLOWING  DISCUSSION  SUMMARIZES  THE  PROPOSED  MERGER  AND  RELATED
TRANSACTIONS. THE  FOLLOWING  IS  NOT,  HOWEVER, A  COMPLETE  STATEMENT  OF  ALL
PROVISIONS OF THE MERGER AGREEMENT AND RELATED AGREEMENTS. DETAILED TERMS OF AND
CONDITIONS  TO THE MERGER AND CERTAIN  RELATED TRANSACTIONS ARE CONTAINED IN THE
MERGER AGREEMENT, A CONFORMED COPY OF WHICH IS ATTACHED TO THIS PROSPECTUS/PROXY
STATEMENT AS ANNEX A.  STATEMENTS MADE IN  THIS PROSPECTUS/PROXY STATEMENT  WITH
RESPECT  TO THE TERMS OF THE MERGER  AND SUCH RELATED TRANSACTIONS ARE QUALIFIED
IN THEIR RESPECTIVE ENTIRETIES BY REFERENCE TO THE MORE DETAILED INFORMATION SET
FORTH IN THE MERGER AGREEMENT.

INFORMIX'S REASONS FOR THE MERGER

    Informix believes that the object-relational database management system that
has  been  developed  and  commercialized  by  Illustra,  when  integrated  with
Informix's  core  database  technology,  will  give  the  combined  companies  a
significant  time-to-market  advantage  over   competing  database  vendors   in
providing   support  for   complex  data,  such   as  audio,   video,  text  and
three-dimensional graphics, in a high performance scalable environment, and that
this time-to-market  advantage  will allow  it  to more  quickly  penetrate  the
complex  data management market, particularly the rapidly-growing new market for
applications developed for the World Wide Web.

ILLUSTRA'S REASONS FOR THE MERGER

    The Illustra Board believes  the Merger will be  beneficial to Illustra  and
its stockholders for the following principal reasons:

    - Because  Informix's  relational database  technology and  products provide
      certain  capabilities  --  such  as  scalability  and  online  transaction
      processing  capability  -- that  presently exceed  those of  Illustra, the
      Illustra Board  believes  a new  set  of products  developed  through  the
      combination  of the two technologies has the potential to generate greater
      customer demand  than  products  based solely  on  Illustra's  technology.
      Although the Illustra Board believes Illustra could, and in the absence of
      the  Merger  would, develop  the  desired capabilities  independently, the
      Illustra Board believes  the Merger will  provide competitively  important
      time-to-market advantages.

    - The customers comprising Informix's significant installed base of database
      products  represent an attractive market  for Illustra's products that the
      Illustra Board  believes can  be addressed  more effectively  through  the
      combined efforts of Informix and Illustra.

    - The  Merger is expected  to provide Illustra  with substantially increased
      marketing, financial  and  personnel  resources for  the  pursuit  of  its
      product development, marketing and sales objectives.

    - As  a result of the Merger, Illustra stockholders will hold Informix stock
      for which there  is a  ready public market,  in contrast  to the  illiquid
      nature of their present holdings of Illustra stock.

    The  Illustra Board believes the Merger is in the best interests of Illustra
and  its  stockholders,  notwithstanding  the  following  potentially   negative
factors:  (i) the potential disruption of  Illustra's business that might result
from employee uncertainty and lack of focus following announcement of the Merger
and during the integration of the operations of Informix and Illustra; (ii)  the
possibility  that the Merger  might not be  consummated, and the  effects of the
public announcement of the Merger on Illustra's sales and operating results, its
ability to attract and retain key management, marketing and technical  personnel
and  the progress of certain  of its development projects;  (iii) the risk that,
despite the  intentions  and  the  efforts  of  the  parties  to  support  their
respective products, the announcement of the Merger could result in decisions by
customers  to defer purchases of products of Informix or Illustra; (iv) the risk
that the  other  benefits sought  to  be achieved  in  the Merger  will  not  be
achieved; and (v) the other risks described above under "Risk Factors."

MATERIAL CONTACTS

    Competition in the market for relational database management system products
is  intense, and Informix commits substantial  resources to enhance its existing
product lines and to develop new  products. With the relatively recent focus  of
many  companies  in the  computer software  industry  on the  opportunities made
possible through the Internet,  the management of  Informix also has  considered
the potential market advantages of database applications developed for the World
Wide  Web. Informix believes that a business strategy that combines complex data
management, including audio,  video, text and  three-dimensional graphics,  with
database  applications  that  can  be  employed  on  the  World  Wide  Web,  can
significantly expand the  market for  database products.  Although Informix  has
taken  steps  during  the  last  year to  begin  development  of  the technology
necessary for  complex data  management products,  Informix believes  that  this
internal  product development effort will require over a year to complete. As an
alternative to  its  internal  development  strategy,  in  1995  Informix  began
considering  the possibility of acquiring the necessary database technology from
an outside party.

    Illustra's object-relational server and related products have been developed
with the specific objective  of optimizing their  functionality with respect  to
complex  multimedia data -- such as audio, video and images -- of the type often
used in World  Wide Web or  other Internet-based applications.  In light of  the
technical complexity of Illustra's products and the critical role major database
management  system products typically play in  the information systems of users,
Illustra's management has been  aware since inception  that the development  and
marketing  of  Illustra's  products  are  substantial  challenges  to Illustra's
long-term success.

    In late May and early June 1995, representatives of the senior management of
Informix contacted the management of Illustra to discuss possible synergies that
might arise from a strategic  relationship between the two companies,  including
through  a licensing arrangement or a merger. These discussions did not progress
beyond exploratory levels and  ended when the management  of Illustra failed  to
indicate any interest in pursuing such a relationship.

    In early November 1995, Phillip E. White, Informix's Chairman, President and
Chief  Executive Officer, initiated contact with Richard H. Williams, Illustra's
President and Chief Executive Officer, to again indicate Informix's interest  in
establishing   a  strategic  relationship,  including  through  a  merger,  with
Illustra. At Mr.  White's suggestion, senior  management representatives of  the
two companies met on three occasions that month to discuss at a conceptual level
the possible synergies that might be realized through combining the technologies
and  products of the two companies. These discussions included evaluation of the
feasibility of  integrating  the  technologies  of the  two  companies  and  the
companies' respective business strategies and corporate cultures.

    On  December 4, 1995, Mr. White of Informix and Mr. Williams of Illustra and
the companies' respective financial advisors met to discuss financial and  other
terms  of a possible merger. Following this meeting, on December 7, the Illustra
Board met  to consider  the principal  financial and  other terms  upon which  a
merger  might be structured and  appointed a committee of  the Board to act with
the full authority of the Board with respect to merger negotiations between  the
two  companies.  Senior management  representatives of  the companies  and their
respective financial  and legal  advisors met  again  on December  8 and  10  to
continue  discussing the principal  terms of a  merger. On December  10, the two
companies entered into a "no-shop"  agreement prohibiting Illustra, directly  or
indirectly,  from taking any action to  solicit, initiate or encourage any offer
or proposal from  any outside party  regarding an acquisition  of Illustra,  and
also  entered a  mutual non-disclosure  agreement prohibiting  the disclosure of
confidential information  provided  by  the  companies.  In  addition,  the  two
companies  on that date agreed  upon an outline of  fundamental terms by which a
merger of  the companies  could  be accomplished,  subject  to completion  of  a
comprehensive  investigation  by Informix  of the  technology and  operations of
Illustra, the negotiation and preparation  of a definitive agreement, and  final
approval  by the  Informix Board  and the  Illustra Board  committee of  such an
agreement.

                                       22
<PAGE>
    On December 12, 1995, Informix provided to Illustra an unsecured $5  million
credit  facility that bears interest at market rates and can be drawn against by
Illustra at any time until the earlier of June 30, 1996 or the completion of the
Merger. Illustra  initially borrowed  $2 million  when the  credit facility  was
established to supplement its working capital.

    Beginning   on  December  18  and  continuing  through  December  20,  1995,
representatives of the two  companies and their  respective legal and  financial
advisors met to negotiate the definitive agreement providing for the Merger. The
Informix  Board  met  each day  during  this  period to  monitor  the  status of
negotiations and Informix's  continuing investigation  of Illustra's  technology
and  operations, and the  members of the Illustra  Board committee monitored the
status of negotiations through communications from Mr. Williams and at a meeting
on December 20. On the afternoon of December 20, following final approval by the
Informix Board  and  the Illustra  Board  committee, the  Merger  Agreement  was
signed.  A joint press release announcing the proposed merger was made that same
day following the close of Informix's trading markets.

RECOMMENDATION OF ILLUSTRA BOARD

    THE ILLUSTRA BOARD  HAS UNANIMOUSLY  APPROVED THE MERGER  AGREEMENT AND  THE
TRANSACTIONS CONTEMPLATED THEREBY AND HAS DETERMINED THAT THE MERGER IS FAIR TO,
AND  IN  THE BEST  INTERESTS OF,  ILLUSTRA AND  ITS STOCKHOLDERS.  AFTER CAREFUL
CONSIDERATION, THE  ILLUSTRA BOARD  UNANIMOUSLY RECOMMENDS  A VOTE  IN FAVOR  OF
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND APPROVAL OF THE MERGER.

EFFECTIVE TIME

   
    The Merger Agreement provides that the Merger will become effective upon the
filing  of a Certificate  of Merger with  the Secretary of  State of Delaware in
accordance with the DGCL (the "Effective  Time"). It is anticipated that if  all
conditions  of the Merger have been fulfilled or waived, the Effective Time will
occur on  or about  February 16,  1996,  or on  a date  as soon  as  practicable
thereafter.
    

MANNER AND BASIS OF CONVERTING SHARES

    As  a result of the Merger, the  maximum number of shares of Informix Common
Stock to be issued (including Informix Common Stock to be reserved for  issuance
upon  exercise  of any  of  Illustra's options  and  warrants to  be  assumed by
Informix) in  exchange  for  the  acquisition by  Informix  of  all  outstanding
Illustra Capital Stock and all unexpired and unexercised options and warrants to
acquire Illustra Capital Stock will be 15,000,000. No adjustment will be made in
the  number of shares of Informix Common Stock  issued in the Merger as a result
of any cash  proceeds received by  Illustra from  the date of  execution of  the
Merger  Agreement to the closing date of  the Merger pursuant to the exercise of
options or warrants to acquire Illustra Capital Stock.

    Subject to  the terms  and conditions  of the  Merger Agreement,  as of  the
Effective  Time, by virtue of  the Merger and without any  action on the part of
Merger Sub, Illustra or the holder of any shares of Illustra Capital Stock,  the
following will occur:

    CONVERSION  OF ILLUSTRA COMMON  STOCK.  Each share  of Illustra Common Stock
issued and outstanding immediately prior to  the Effective Time (other than  any
Dissenting   Shares)  will  be  canceled   and  extinguished  and  be  converted
automatically into the right to receive that number of shares of Informix Common
Stock equal to the Common Exchange  Ratio (as defined below), upon surrender  of
the  certificate representing such share of  Illustra Common Stock in the manner
provided in a letter of transmittal to be sent to each record holder of Illustra
Capital Stock promptly following the Effective Time (a "Letter of Transmittal"),
including, with  respect to  each whole  share of  Informix Common  Stock to  be
received,  the right to  receive one preferred share  purchase right (a "Right")
under Informix's Amended and Restated Preferred Shares Rights Agreement dated as
of September 12, 1991 and amended and restated  as of May 15, 1992 and July  25,
1995,  and in any case, subject to the escrow provisions of the Merger Agreement
described under  the  section  entitled  "Approval of  the  Merger  and  Related
Transactions -- Escrow Fund" below.

                                       23
<PAGE>
   
    The "Common Exchange Ratio" will depend on the capitalization of Illustra at
the  Effective Time.  Assuming that all  shares of Illustra  Preferred Stock are
converted to shares of  Illustra Common Stock prior  to the Effective Time,  and
further assuming that the capitalization of Illustra at the Effective Time is in
all  other respects  identical to the  capitalization of Illustra  at January 2,
1996 (although  there can  be no  assurance  as to  the foregoing),  the  Common
Exchange  Ratio will  be 0.77184 of  a share  of Informix Common  Stock for each
share of Illustra Common Stock. In any event, the Common Exchange Ratio will  be
calculated  at the Effective  Time and will  be equal to  the number obtained by
dividing (i) 15,000,000  MINUS the  number of  shares of  Informix Common  Stock
issuable  by virtue  of the  Merger in respect  of shares  of Illustra Preferred
Stock that remain outstanding and not  converted into shares of Illustra  Common
Stock  immediately prior to the Effective Time (or are issuable upon exercise of
then outstanding options  or warrants  to acquire shares  of Illustra  Preferred
Stock) MINUS the number of shares of Informix Common Stock issuable by virtue of
the Merger in respect of the aggregate Series C Additional Conversion Shares (as
defined  below), DIVIDED BY  (ii) the sum  of the aggregate  number of shares of
Illustra Common  Stock  outstanding  immediately prior  to  the  Effective  Time
(taking  into  account all  shares  of Illustra  Preferred  Stock that  shall be
converted into Illustra Common Stock as of such time) PLUS the aggregate  number
of shares of Illustra Common Stock issuable upon the exercise of all outstanding
options  and warrants  to acquire  shares of  Illustra Common  Stock immediately
prior to the Effective Time. The  Common Exchange Ratio and the exchange  ratios
relating to shares of Illustra Preferred Stock will be adjusted to reflect fully
the  effect of  any stock  split, reverse  split, stock  dividend (including any
dividend or distribution of securities convertible into Informix Common Stock or
Illustra Capital Stock), reorganization,  recapitalization or other like  change
with  respect to Informix Common Stock or Illustra Capital Stock occurring after
the date of execution of the Merger Agreement and prior to the Effective Time.
    

    CONVERSION OF  ILLUSTRA PREFERRED  STOCK; TREATMENT  OF CONVERTED  SERIES  C
PREFERRED STOCK.  Each share of Series A Preferred, Series B Preferred, Series C
Preferred and Series D Preferred issued and outstanding immediately prior to the
Effective  Time  (other than  any shares  of Illustra  Preferred Stock  that are
converted into  shares  of  Illustra  Common  Stock  immediately  prior  to  the
Effective  Time and any Dissenting Shares) will be canceled and extinguished and
be converted automatically into the  right to receive 0.03728, 0.05825,  0.08738
and  0.11650 of a  share of Informix Common  Stock, respectively (the "Preferred
Exchange Ratios"), upon surrender of the certificate representing such share  of
Illustra  Preferred Stock in  the manner provided in  the Letter of Transmittal,
including, with  respect to  each whole  share of  Informix Common  Stock to  be
received,  one Right, and in  any case, subject to  the escrow provisions of the
Merger Agreement described under  the section entitled  "Approval of the  Merger
and  Related Transactions --  Escrow Fund" below.  The Preferred Exchange Ratios
were determined  in accordance  with  the Amended  and Restated  Certificate  of
Incorporation  of  Illustra  for  each series  of  Illustra  Preferred  Stock by
dividing the liquidation preference for each share in such series by $25.75, the
closing price of Informix Common Stock on Nasdaq on December 20, 1995, the  date
on which the Merger Agreement was executed.

    Holders of Illustra Preferred Stock should note that the number of shares of
Informix  Common Stock which they will be entitled to receive in respect of each
share of Illustra Preferred Stock held by  them by virtue of the Merger will  be
significantly  greater if such shares of  Illustra Preferred Stock are converted
into shares of  Illustra Common Stock  prior to the  Effective Time.  Illustra's
Certificate  of  Incorporation provides  that the  proposed Merger  as described
herein would be treated as a liquidation of Illustra, in which event the holders
of Preferred Stock of  Illustra would only receive  proceeds from the Merger  to
the  extent of their liquidation preferences set forth in Illustra's Certificate
of Incorporation. Such proceeds  would be substantially  less than the  proceeds
which  would  be received  if  the Illustra  Preferred  Stock were  converted to
Illustra Common Stock prior to the Effective  Time of the Merger. The holder  of
all  of the Series C Preferred has  already executed and delivered to Illustra a
notice indicating its  irrevocable election to  convert its shares  of Series  C
Preferred  into Illustra Common  Stock immediately prior  to the Effective Time.
Holders of a sufficient  number of shares of  Illustra Preferred Stock to  cause
the   automatic   conversion  of   all  other   shares  of   Illustra  Preferred

                                       24
<PAGE>
Stock into shares of Illustra Common  Stock have entered into Voting  Agreements
with  Informix, which provide for their irrevocable election to vote in favor of
such conversion immediately prior to the Effective Time.

    The Certificate of Incorporation of Illustra currently provides that if  and
to the extent shares of Series C Preferred are converted into shares of Illustra
Common  Stock prior to the date which  is ten business days after Illustra first
receives copies of  its audited financial  statements for the  1996 fiscal  year
(the  "Conversion Calculation  Date"), the number  of shares  of Illustra Common
Stock that shall be deliverable upon conversion of a share of Series C Preferred
provisionally shall be deemed  to be a fixed  amount (the "Conversion  Amount"),
and  the Conversion  Amount shall  be subject to  increase based  on events that
would be determinable on  the Conversion Calculation  Date (the Illustra  Common
Stock  that would constitute an  increase to the Conversion  Amount per share of
Series C  Preferred is  hereinafter  referred to  as  the "Series  C  Additional
Conversion  Share";  and  thus  one  right  to  receive  a  Series  C Additional
Conversion Share would be outstanding for each share of Series C Preferred  that
is  converted into  Illustra Common  Stock prior  to the  Conversion Calculation
Date). Based  on  the foregoing  and  the terms  and  conditions of  the  Merger
Agreement,  in the event that the Effective  Time occurs prior to the Conversion
Calculation Date,  then by  virtue  of the  Merger,  each outstanding  right  to
receive  a  Series  C  Additional  Conversion  Share  immediately  prior  to the
Effective Time will be canceled and extinguished and be converted  automatically
into  the right to receive that number  of shares of Informix Common Stock equal
to 0.25 times  the Common Exchange  Ratio, upon surrender  of a certificate  (or
other  evidence  reasonably  satisfactory  to Informix  or  the  exchange agent)
representing such Series C Additional Conversion Share in the manner provided in
the Letter  of Transmittal,  including,  with respect  to  each whole  share  of
Informix Common Stock to be received, one Right, and in any case, subject to the
escrow  provisions of the Merger Agreement  described under the section entitled
"Approval of the Merger and Related Transactions -- Escrow Fund" below.

    STOCK OPTIONS.   At the  Effective Time, each  outstanding Illustra  Option,
whether  vested or unvested, will be, in  connection with the Merger, assumed by
Informix. Each Illustra Option so assumed by Informix under the Merger Agreement
will continue to  have, and be  subject to,  the same terms  and conditions  set
forth  in the Option Plan and/or as provided in the respective option agreements
governing such Illustra Option immediately  prior to the Effective Time,  except
that  (i) such  Illustra Option  will be  exercisable for  that number  of whole
shares of Informix Common Stock equal to the product of the number of shares  of
Illustra  Common Stock that were issuable  upon exercise of such Illustra Option
immediately prior to the Effective Time multiplied by the Common Exchange Ratio,
rounded down (in the case of Illustra Options granted under the Option Plan)  to
the  nearest whole number  of shares of  Informix Common Stock  and (ii) the per
share exercise  price for  the shares  of Informix  Common Stock  issuable  upon
exercise  of  such  assumed  Illustra  Option  will  be  equal  to  the quotient
determined by dividing the exercise price per share of Illustra Common Stock  at
which  such Illustra Option  was exercisable immediately  prior to the Effective
Time by the Common Exchange Ratio, rounded  up to the nearest whole cent. It  is
the  intention of  Informix and  Illustra that  the Illustra  Options assumed by
Informix qualify following the Effective  Time as incentive stock options  under
the Code to the extent the Illustra Options qualified as incentive stock options
immediately prior to the Effective Time.

    In connection with the Merger, the Illustra Common Stock subject to an early
exercise  stock purchase agreement  under the Option Plan  will be exchanged for
Informix Common Stock at the Common  Exchange Ratio, and the shares of  Informix
Common  Stock so received  shall continue to  be subject to  the same repurchase
right in favor of the surviving corporation, which the surviving corporation may
assign to Informix.  The number of  shares of Informix  Common Stock subject  to
repurchase from time to time after the Merger and the repurchase price per share
shall be appropriately adjusted to reflect the exchange of Illustra Common Stock
for Informix Common Stock.

    WARRANTS.    Each warrant  to purchase  shares  of Illustra  Preferred Stock
outstanding at  the Effective  Time  will be,  in  connection with  the  Merger,
assumed  by  Informix. Each  warrant  so assumed  by  Informix under  the Merger
Agreement will  continue  to  have,  and  be subject  to,  the  same  terms  and

                                       25
<PAGE>
conditions set forth in the warrant agreement governing such warrant immediately
prior  to the Effective Time, except that  each such warrant will, following the
Effective Time, be exercisable only for shares of Informix Common Stock, in such
number, and at such exercise price as is determined by applying the  appropriate
exchange ratio in accordance with the terms of the applicable warrant agreement.

STOCK OWNERSHIP FOLLOWING THE MERGER

   
    Based  upon the  capitalization of  Illustra as of  January 2,  1996 and the
Exchange Ratio Assumptions, an aggregate  of approximately 12,315,000 shares  of
Informix  Common Stock will be issued to Illustra stockholders in the Merger and
Informix will assume options exercisable  for up to an additional  approximately
2,685,000  shares of Informix Common  Stock. Based upon the  number of shares of
Informix Common Stock issued and outstanding as of December 31, 1995, and  after
giving  effect to the issuance  of Informix Common Stock  in connection with the
Merger (assuming no exercise of appraisal or dissenters' rights and assuming  no
exercise  prior to the Merger as described in the previous sentence), the former
holders of Illustra Capital  Stock would hold  approximately 8.3% of  Informix's
total issued and outstanding shares and holders of former Illustra Options would
hold options to acquire Informix Common Stock exercisable for approximately 1.8%
of Informix's total issued and outstanding shares (assuming the exercise of only
such  options). The foregoing  numbers of shares and  percentages are subject to
change in the event  that the capitalization of  Illustra changes subsequent  to
January 2, 1996 and prior to the Effective Time and there can be no assurance as
to the actual capitalization of Illustra at the Effective Time.
    

ESCROW FUND

    In  connection with the Merger, at the  Effective Time, 10% of the shares of
Informix Common Stock otherwise issuable to holders of Illustra Capital Stock by
virtue of the Merger (the "Escrow Shares") will be registered in the name of and
deposited with the Escrow Agent, such deposit to constitute the Escrow Fund. The
Escrow Shares shall be contributed to the  Escrow Fund on behalf of each  holder
of  Illustra Capital Stock  in proportion to  the aggregate number  of shares of
Informix Common  Stock such  holder would  otherwise receive  by virtue  of  the
Merger.  No portion  of the Escrow  Fund will  be contributed in  respect of any
options or warrants  to acquire  shares of  Illustra Capital  Stock. The  Escrow
Shares will be held in escrow as security for any losses that Informix incurs or
reasonably  anticipates incurring by  reason of certain  breaches by Illustra of
covenants, representations  or  warranties  contained in  the  Merger  Agreement
including,  without limitation,  those relating  to Illustra's  organization and
standing,  capital  structure,  authority,  financial  statements,  absence   of
changes,  taxes, title  to properties  and condition  of equipment, intellectual
property, material  contracts,  environmental  matters,  employee  matters,  and
compliance  with laws.  The Illustra stockholders  will have  voting rights with
respect to the Escrow Shares while in escrow. Resort to the Escrow Fund will  be
the  exclusive  contractual  remedy  of  Informix  for  any  such  breaches  and
misrepresentations if the Merger  closes, provided that  nothing will limit  any
remedy   for   fraud.   Notwithstanding  the   foregoing,   except   in  limited
circumstances, Informix may not receive any  shares from the Escrow Fund  unless
and  until  losses in  excess  of $500,000  have  been suffered,  in  which case
Informix may recover  from the Escrow  Fund an  amount of Escrow  Shares with  a
value equal to the total of its losses in excess of $500,000. For the purpose of
compensating  Informix for its losses, the Escrow  Shares shall be valued at the
average of the closing prices of Informix Common Stock for the five  consecutive
trading  days ending  two days prior  to the  closing of the  Merger. Subject to
resolution of unsatisfied claims  of Informix, the  Escrow Fund shall  terminate
upon  the earlier of (i) twelve months  following the closing date of the Merger
and (ii) the issuance of Informix's audited financial statements for fiscal year
ending December 31, 1996.

    BY APPROVING THE MERGER AGREEMENT,  ILLUSTRA STOCKHOLDERS WILL BE DEEMED  TO
HAVE  CONSENTED  TO THE  APPOINTMENT OF  GARY J.  MORGENTHALER, AN  AFFILIATE OF
MORGENTHALER VENTURE PARTNERS III, WHICH IS A STOCKHOLDER OF ILLUSTRA, TO ACT AS
THE SECURITYHOLDER AGENT ON BEHALF OF ILLUSTRA'S STOCKHOLDERS TO DELIVER  SHARES
HELD  IN ESCROW TO  INFORMIX IN SATISFACTION  OF CLAIMS BROUGHT  BY INFORMIX, TO
OBJECT TO  SUCH  DELIVERIES,  TO  AGREE  TO, TO  NEGOTIATE  AND  TO  ENTER  INTO
SETTLEMENTS   AND   COMPROMISES   WITH   RESPECT   TO   SUCH   CLAIMS,   AND  TO

                                       26

TAKE CERTAIN OTHER  ACTION ON  BEHALF OF  ILLUSTRA'S STOCKHOLDERS,  ALL AS  MORE
FULLY  DESCRIBED IN ARTICLE VII OF THE  MERGER AGREEMENT. SEE ARTICLE VII OF THE
MERGER AGREEMENT FOR A MORE DETAILED  EXPLANATION OF THE ESCROW FUND AND  RIGHTS
WITH RESPECT THERETO.

LEGAL STRUCTURE OF THE MERGER

    Under  the  Merger  Agreement,  Merger  Sub,  a  wholly-owned  subsidiary of
Informix formed  for  this purpose,  will  merge  with and  into  Illustra  with
Illustra   being  the  surviving  corporation  of  the  Merger  (the  "Surviving
Corporation").  The  Certificate  of  Incorporation  of  Merger  Sub  in  effect
immediately  prior  to  the  Effective  Time  will  become  the  Certificate  of
Incorporation of the Surviving Corporation, the Bylaws of Merger Sub will become
the Bylaws of the Surviving Corporation and the Board of Directors of Merger Sub
will become the Board of Directors of the Surviving Corporation.

CONDUCT OF ILLUSTRA'S BUSINESS PRIOR TO THE MERGER

    Under the Merger Agreement, Illustra has agreed, during the period from  the
date of the Merger Agreement and continuing until the earlier of the termination
of  the Merger Agreement pursuant to its terms and the Effective Time, except to
the extent that Informix otherwise consents in writing, that Illustra will carry
on its business in the usual,  regular and ordinary course in substantially  the
same manner as previously conducted, to pay its debts and taxes when due subject
to  good  faith disputes  over  such debts  or taxes,  to  pay or  perform other
material obligations when due, and to use all reasonable efforts consistent with
past practices  and  policies to  preserve  intact Illustra's  present  business
organizations, keep available the services of its present officers and employees
and   preserve  its  relationships   with  customers,  suppliers,  distributors,
licensors, licensees, and others having business dealings with Illustra, to  the
end  that  Illustra's  goodwill  and ongoing  businesses  be  unimpaired  in all
material respects at the Effective Time. Among other things, Illustra has agreed
that, subject to  certain specific exceptions,  it will not,  without the  prior
written consent of Informix:

    issue or authorize the  issuance of any other  securities in respect of,  in
    lieu  of or  in substitution  for shares  of capital  stock of  Illustra, or
    repurchase, redeem or otherwise acquire, directly or indirectly, any  shares
    of  its  capital stock  (or options,  warrants  or other  rights exercisable
    therefor);

        (g) except for  the issuance of  shares of Illustra  Capital Stock  upon
    exercise  or conversion of presently  outstanding Illustra Options, warrants
    or Illustra Preferred Stock, or the grant of stock options to new  employees
    pursuant  to outstanding written offers of employment, issue, grant, deliver
    or sell or authorize or propose the issuance, grant, delivery or sale of, or
    purchase or propose  the purchase  of, any shares  of its  capital stock  or

    or assets, except in the ordinary course of business;

        (k) incur  any indebtedness  for borrowed  money or  guarantee any  such
    indebtedness  or issue or sell any  debt securities of Illustra or guarantee

    remuneration  to any director or employee,  or increase the salaries or wage

    ordinary  course of business of liabilities reflected or reserved against in
    the Illustra financial statements attached  to the Merger Agreement or  that

    described above,  or  any other  action  that would  prevent  Illustra  from
    performing or cause Illustra not to perform its covenants hereunder.

NO SOLICITATION

    The  Merger Agreement provides that Illustra  shall not, and shall cause its
directors, officers, employees, representatives,  agents and affiliates not  to,
directly  or  indirectly, (a)  solicit, conduct  discussions  with or  engage in
negotiations with any person, relating  to the possible acquisition of  Illustra
or any of its subsidiaries (whether by way of merger, purchase of capital stock,
purchase of assets or otherwise) or any material portion of its or their capital
stock or assets, (b) provide information with respect to it to any person, other
than  Informix, relating to the possible acquisition of Illustra (whether by way
of merger, purchase of  capital stock, purchase of  assets or otherwise) or  any
material  portion of  its or their  capital stock  or assets, (c)  enter into an
agreement with any person, other than Informix, providing for the acquisition of
Illustra (whether  by way  of merger,  purchase of  capital stock,  purchase  of
assets  or otherwise) or any  material portion of its  or their capital stock or
assets or (d) make or authorize any statement, recommendation or solicitation in
support of  any possible  acquisition of  Illustra or  any of  its  subsidiaries
(whether  by way  of merger,  purchase of capital  stock, purchase  of assets or
otherwise) or any material portion  of its or their  capital stock or assets  by

                                       28
<PAGE>
any  person, other than by Informix. In  addition to the foregoing, Illustra has
agreed that if it receives prior to the Effective Time or the termination of the
Merger Agreement any offer or  proposal relating to any  of the above, it  shall
promptly  notify  Informix  thereof,  and will  provide  information  as  to the
identity of the offeror or the party  making any such offer or proposal and  the
specific  terms of such  offer or proposal, as  the case may  be, and such other
information related thereto as Informix may reasonably request.

EXPENSES; FEES

    Except as set forth below, all fees and expenses incurred in connection with
the Merger Agreement and the transactions  contemplated thereby will be paid  by
the party incurring such expenses, whether or not the Merger is consummated.

    If  the Merger Agreement  is terminated by  Informix as a  result of certain
breaches of the Merger Agreement on the part of Illustra, other than as a result
of a  knowing or  willful breach  by Illustra,  then, within  two business  days
following  such termination by Informix, Illustra  has agreed to pay to Informix
the sum of $12 million as liquidated damages for the breach giving rise to  such
termination.  Nothing in the Merger Agreement,  however, limits the liability of
Illustra for any knowing or willful breaches of the Merger Agreement on the part
of Illustra. If the Merger  Agreement is terminated by  Illustra as a result  of
certain  breaches of the Merger Agreement on the part of Informix, other than as
a result of a knowing or willful  breach by Informix, then, within two  business
days  following  such termination  by Illustra,  Informix has  agreed to  pay to
Illustra the sum of $12 million as liquidated damages for the breach giving rise
to such  termination.  Nothing in  the  Merger Agreement,  however,  limits  the
liability  of  Informix  for  any  knowing or  willful  breaches  of  the Merger
Agreement on the part of Informix.

that the right to terminate the Merger Agreement under this clause (b) shall not

(ii) compel Informix or Illustra to dispose of or hold separate, as a result  of
the  Merger, any portion of  the business or assets  of Illustra or Informix; in
either case,  the  unavailability of  which  assets  or business  would  have  a
material  adverse effect on Informix  or would reasonably be  expected to have a
material adverse effect on Informix's  ability to realize the benefits  expected
from  the  Merger, (d)  by  Informix if  it  is not  in  material breach  of its
obligations under  the Merger  Agreement and  there  has been  a breach  of  any
representation,   warranty,  covenant  or  agreement  contained  in  the  Merger
Agreement on  the part  of  Illustra and  as a  result  of such  breach  certain
conditions  to the Merger set forth above would not then be satisfied; provided,
however, that if such breach is  curable by Illustra within thirty days  through
the exercise of its reasonable best efforts,

                                       30
<PAGE>
then  for so long as Illustra continues to exercise such reasonable best efforts
Informix may not  terminate the Merger  Agreement under this  clause (d)  unless
such  breach  is not  cured  within thirty  days (but  no  cure period  shall be
required for a breach which by its  nature cannot be cured), (e) by Illustra  if
it  is not in material breach of  its obligations under the Merger Agreement and
there has been a breach of  any representation, warranty, covenant or  agreement
contained in the Merger Agreement on the part of Informix or Merger Sub and as a
result of such breach certain conditions to the Merger set forth above would not
then be satisfied; provided, however, that if such breach is curable by Informix
or  Merger Sub within  thirty days through  the exercise of  its reasonable best
efforts, then for so long as Informix  or Merger Sub continues to exercise  such
reasonable  best efforts Illustra  may not terminate  the Merger Agreement under
this clause (e) unless such breach is not cured within thirty days (but no  cure
period shall be required for a breach which by its nature cannot be cured).

VOTING AGREEMENTS

   
    Each of Accel IV L.P. and affiliated entities, Morgenthaler Venture Partners
III, Oak Investment Partners IV and an affiliated entity, Bruce Golden, Paula B.
Hawthorn, Harvey C. Jones, Stephen G. Maysonave, Michael R. Stonebraker, Michael
C.  Ubell and Richard H.  Williams (who own an  aggregate of 2,537,300 shares of
Illustra  Common  Stock  and  7,483,503  shares  of  Illustra  Preferred   Stock
representing  approximately 58.7% and 66.4%, respectively, of the votes entitled
to be cast by holders of shares of Illustra Common Stock and Illustra  Preferred
Stock  issued and outstanding as  of January 2, 1996)  has entered into a Voting
Agreement with Informix. Each of the foregoing individuals and entities has been
identified by Illustra as an "affiliate"  (as that term is defined for  purposes
of  Rule 145 promulgated under the Securities  Act) of Illustra. Pursuant to the
Voting Agreements,  which  are  irrevocable,  each  of  the  foregoing  Illustra
stockholders  has agreed to vote in favor of approval and adoption of the Merger
Agreement and approval  of the Merger.  The vote in  accordance with the  Voting
Agreements  of the shares of Illustra  Common Stock and Illustra Preferred Stock
subject to  the  Voting  Agreements  will be  adequate  to  approve  the  Merger
Agreement and the Merger by Illustra stockholders.
    

CERTAIN BENEFITS TO ILLUSTRA MANAGEMENT AND EMPLOYEES

    Following  the Effective  Time, Informix has  advised Illustra  that it will
appoint Richard H. Williams, Illustra's  President and Chief Executive  Officer,
and  Michael R. Stonebraker,  Illustra's Chief Technology  Officer, as executive
officers of Informix. Each  of Messrs. Williams and  Stonebraker is expected  to
receive compensation, including equity participation in Informix's equity plans,
consistent  with the compensation levels of other senior management of Informix.
In  addition,  Informix  has  indicated  that  it  presently  intends  to  offer
employment,  through Informix (or its subsidiaries), to all or substantially all
of the employees of  Illustra following the Effective  Time. Such employment  is
expected  to be  on an  "at will" basis  at the  discretion of  Informix (or its
subsidiaries)  and  the  employee.   See  "Illustra  Management  and   Executive
Compensation -- Management."

    The  Merger Agreement also provides  that, commencing with the effectiveness
of the Merger, Informix  will either cause Illustra  to or will itself  directly
indemnify  the current  officers and  directors of  Illustra in  accordance with
Illustra's Bylaws in  effect immediately  before the  Merger for  any action  or
inaction by such person prior to the Merger.

NON-COMPETITION AGREEMENTS

    Certain   officers  and  other  employees  of  Illustra  have  entered  into
non-competition agreements  with Informix  and Illustra.  These persons  include
Richard   H.  Williams,  President  and  Chief  Executive  Officer,  Michael  R.
Stonebraker, Chief Technology Officer, Bruce Golden, Vice President,  Marketing,
Paula  B. Hawthorn,  Vice President,  Engineering, Stephen  G. Maysonave, Senior
Vice  President,   Sales,   and  Michael   C.   Ubell,  Chief   Scientist.   The
non-competition  agreements contain  provisions restricting  such persons  for a
period of two years  following the closing of  the Merger from participating  or
engaging in the design, development, manufacture, production, marketing, sale or
servicing  of any  product or  the provision  of any  service, that  directly or
indirectly competes with Illustra's or

                                       31
<PAGE>
Informix's products  or services.  These restrictions  cease if  the  restricted
party's  employment is terminated  by Informix or Illustra  other than for cause
(as defined in the non-competition agreements) and  other than as a result of  a
voluntary resignation.

AFFILIATE AGREEMENTS

    The Informix Common Stock to be issued pursuant to the Merger will be freely
transferable  under the Securities  Act, except for shares  issued to any person
who is an "affiliate" of  Informix or Illustra within  the meaning of Rules  144
and  145 under the Securities Act. Rules  144 and 145 impose restrictions on the
manner in which such affiliates may  resell securities and also on the  quantity
of  securities  that such  affiliates and  others  with whom  they might  act in
concert may resell within any three-month period.

    As a condition to the Merger, prior  to the Effective Time, each person  who
has  been identified by Illustra as an affiliate of Illustra is required to have
entered into an  agreement with  Informix providing  that such  person will  not
offer  to sell or otherwise  dispose of any Informix  Common Stock obtained as a
result of the Merger except in compliance with the Securities Act and the  rules
and  regulations thereunder. Generally this will require that such sales be made
in accordance with Rule 145(d) under the Securities Act, which in turn  requires
that,  for specified periods, such  sales be made in  compliance with the volume
limitations, manner of sale provisions  and current information requirements  of
Rule  144 under the Securities  Act. The volume limitations  should not pose any
material limitations on any Informix stockholder who owns less than one  percent
of  the outstanding Informix  Common Stock after the  Merger unless, pursuant to
Rule 144, such stockholder's shares are required to be aggregated with those  of
another stockholder and together they exceed the one percent threshold.

    In  order to help ensure that the  Merger will qualify as a "reorganization"
under Section 368(a)  of the Code,  the affiliate agreements  to be executed  by
each  affiliate of Illustra contain a  representation that such affiliate has no
plan or intention to sell any of the shares of Informix Common Stock received in
the Merger (and will have no such plan or intention at the Effective Time).

   
    In order to  help ensure that  the Merger will  be treated as  a pooling  of
interests  for financial reporting purposes, affiliate agreements to be executed
by affiliates of  both Illustra and  Informix provide that  such affiliate  will
not,  subject to a de minimis exception, (i) sell, transfer or otherwise dispose
of any shares of Illustra Capital Stock or any shares of Informix Common  Stock,
or  (ii) in any way reduce such affiliate's interest in or risk relating to such
shares of Illustra  Capital Stock or  Informix Common Stock,  during the  period
from  at least thirty days prior to the Effective Time until two days after such
time as results of combined sales and  net income covering at least thirty  days
of  combined operations of Illustra and Informix have been published by Informix
in the form of a quarterly earnings report, an effective registration  statement
filed  with the SEC, a report to the SEC on Form 10-K, 10-Q or 8-K, or any other
public filing or announcement which includes such results of combined sales  and
net income.
    

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

    The   following  discussion  summarizes  the  material  federal  income  tax
considerations of  the  Merger  that  are generally  applicable  to  holders  of
Illustra  Capital  Stock. This  discussion  does not  deal  with all  income tax
considerations that may be relevant to particular Illustra stockholders in light
of their  particular circumstances,  such  as stockholders  who are  dealers  in
securities,  foreign  persons,  or  stockholders who  acquired  their  shares in
connection with stock option  or stock purchase plans  or in other  compensatory
transactions.  In addition,  the following discussion  does not  address the tax
consequences of transactions effectuated prior  to or after the Merger  (whether
or  not such transactions are in  connection with the Merger), including without
limitation transactions in  which shares of  Illustra Common Stock  were or  are
acquired  or shares of Informix Common  Stock (including the Escrow Shares) were
or are disposed of. Furthermore, no  foreign, state or local tax  considerations
are  addressed herein. ACCORDINGLY,  ILLUSTRA STOCKHOLDERS ARE  URGED TO CONSULT

                                       32
<PAGE>
THEIR OWN  TAX ADVISORS  AS TO  THE  SPECIFIC TAX  CONSEQUENCES OF  THE  MERGER,
INCLUDING  THE APPLICABLE FEDERAL, STATE, LOCAL  AND FOREIGN TAX CONSEQUENCES TO
THEM OF THE MERGER.

    The Merger is intended to  constitute a "reorganization" within the  meaning
of  Section 368(a) of the  Code, with each of  Informix, Merger Sub and Illustra
intended to qualify as a "party  to the reorganization" under Section 368(b)  of
the  Code, in  which case the  following tax consequences  will generally result
(subject to the limitations and qualifications referred to herein):

        (a) No gain or  loss will be recognized  by holders of Illustra  Capital
    Stock  solely  upon their  receipt of  Informix Common  Stock in  the Merger
    (except to  the  extent of  cash  received in  lieu  of a  fractional  share
    thereof) in exchange therefor;

        (b)  The aggregate tax basis of the Informix Common Stock (including the
    Escrow Shares) received in the Merger by a Illustra stockholder will be  the
    same  as the  aggregate tax basis  of Illustra Capital  Stock surrendered in
    exchange therefor;

        (c) The  holding period  of  the Informix  Common Stock  (including  the
    Escrow Shares) received in the Merger by a Illustra stockholder will include
    the  period during  which the  stockholder held  the Illustra  Capital Stock
    surrendered in exchange therefor, provided  that the Illustra Capital  Stock
    is held as a capital asset at the time of the Merger;

        (d) A Illustra stockholder who exercises appraisal or dissenters' rights
    with  respect to all of such holder's  shares of Illustra Capital Stock will
    generally recognize gain or loss  for federal income tax purposes,  measured
    by  the difference between the holder's basis  in such shares and the amount
    of  cash  received,  provided  that  the  payment  is  neither   essentially
    equivalent  to a dividend within the meaning  of Section 302 of the Code nor
    has the effect of a distribution of a dividend within the meaning of Section
    356(a)(2) of the Code  (collectively, a "Dividend Equivalent  Transaction").
    Such  gain or loss will be capital  gain or loss, provided that the Illustra
    Capital Stock is held as a capital asset  at the time of the Merger. A  sale
    of Illustra Capital Stock pursuant to an exercise of dissenters' rights will
    generally  not be a Dividend Equivalent Transaction  if, as a result of such
    exercise, the stockholder  exercising dissenters' rights  owns no shares  of
    Informix  Common  Stock  or  Illustra  Capital  Stock  (either  actually  or
    constructively within the meaning of Section 318 of the Code). If,  however,
    a  stockholder's  sale for  cash of  Illustra Capital  Stock pursuant  to an
    exercise of dissenters'  rights is a  Dividend Equivalent Transaction,  then
    such stockholder will generally recognize ordinary income for federal income
    tax purposes in an amount up to the entire amount of cash so received;

        (e)  Cash payments in lieu of a fractional share will be treated as if a
    fractional share of Informix Common Stock had been issued in the Merger  and
    then  redeemed by Informix. A Illustra  stockholder receiving such cash will
    generally recognize gain or loss upon  such payment equal to the  difference
    (if  any) between such  stockholder's basis in the  fractional share and the
    amount of cash received; and

        (f) None of  Informix, Merger  Sub or Illustra  will recognize  material
    amounts of gain or loss solely as a result of the Merger.

    The  parties are not  requesting a ruling from  the Internal Revenue Service
("IRS") in connection  with the  Merger. As a  condition to  the obligations  of
Illustra and Informix to consummate the Merger, which condition is not waivable,
Illustra and Informix will receive opinions from their respective legal counsel,
Cooley  Godward Castro Huddleson  & Tatum and Wilson  Sonsini Goodrich & Rosati,
Professional Corporation, to the effect  that, for federal income tax  purposes,
the  Merger will  constitute a  "reorganization" within  the meaning  of Section
368(a) of the Code. These opinions, which are collectively referred to herein as
the "Tax Opinions," neither bind  the IRS nor preclude  the IRS from adopting  a
contrary  position. In  addition, the  Tax Opinions  will be  subject to certain
assumptions and qualifications and  will be based on  the truth and accuracy  of
certain   representations  made  by  Informix,   Merger  Sub  and  Illustra  and
stockholders   of   Illustra,   including   representations   in    certificates

                                       33
<PAGE>
to be delivered to counsel by the respective managements of Informix, Merger Sub
and Illustra and certain stockholders of Illustra. Of particular importance will
be  certain  assumptions  and  representations relating  to  the  "continuity of
interest" requirement.

    To satisfy  the continuity  of interest  requirement, Illustra  stockholders
must  not, pursuant  to a  plan or intent  existing at  or prior  to the Merger,
dispose of or transfer  so much of  either (i) their  Illustra Capital Stock  in
anticipation  of the Merger or (ii) the  Informix Common Stock to be received in
the Merger  (collectively,  "Planned  Dispositions"),  such  that  the  Illustra
stockholders,  as a group, would no longer have substantial proprietary interest
in the Illustra business being conducted  by Informix after the Merger.  Planned
Dispositions  include, among  other things, shares  disposed of  pursuant to the
exercise of dissenters' rights. Illustra stockholders will generally be regarded
as having retained a  substantial proprietary interest as  long as the  Informix
Common   Stock  received  in  the  Merger   (after  reduction  for  any  Planned
Dispositions), in the aggregate, represents a substantial portion of the  entire
consideration  received  by  the Illustra  stockholders  in the  Merger.  If the
continuity of interest requirement were not  satisfied, the Merger would not  be
treated as a "reorganization."

    A  successful IRS challenge to the "reorganization" status of the Merger (as
a result of a failure of the "continuity of interest" requirement or  otherwise)
would  result in a Illustra stockholder recognizing gain or loss with respect to
each share of Illustra Capital Stock surrendered equal to the difference between
the stockholder's basis  in such  share and  the fair  market value,  as of  the
Effective  Time of the Merger, of the Informix Common Stock received in exchange
therefor. In such event, a stockholder's aggregate basis in the Informix  Common
Stock  so received  would equal  its fair  market value  and his  or her holding
period for such stock would begin the day after the Merger.

    Even if the Merger qualifies as a "reorganization," a recipient of shares of
Informix Common  Stock may  recognize income  or gain  to the  extent that  such
shares  were  considered to  be received  in exchange  for services  or property
(other than solely Illustra Capital  Stock), in which case  all or a portion  of
such income or gain may be taxable as ordinary income. In addition, gain or loss
may  have to be recognized to the extent that a Illustra stockholder was treated
as receiving (directly or indirectly)  consideration other than Informix  Common
Stock in exchange for his or her Illustra Capital Stock.

GOVERNMENTAL AND REGULATORY APPROVALS

    Other  than  compliance  with  the federal  securities  laws  and applicable
securities laws of  the various states,  Informix and Illustra  are aware of  no
governmental or regulatory approvals required for consummation of the Merger.

ACCOUNTING TREATMENT

    The  Merger is intended to  qualify as a pooling  of interests for financial
reporting purposes in accordance with generally accepted accounting  principles.
Consummation  of the Merger is conditioned upon receipt by Informix and Illustra
of letters from  Ernst & Young  LLP, Informix's independent  auditors, and  KPMG
Peat  Marwick  LLP, Illustra's  independent  auditors, reaffirming  those firms'
concurrence with Informix  management's and  Illustra management's  conclusions,
respectively,  as to the appropriateness  of pooling-of-interests accounting for
the Merger  under APB  No. 16,  if  consummated in  accordance with  the  Merger
Agreement.

APPRAISAL AND DISSENTERS' RIGHTS

    Stockholders  of Illustra who do not vote  in favor of the Merger may, under
certain circumstances and  by following  the procedure prescribed  by the  DGCL,
exercise  appraisal rights and receive cash for their shares of Illustra Capital
Stock. Alternatively,  although  Illustra  is  a  Delaware  corporation  and  is
therefore subject to the DGCL, the CGCL provides that Illustra may be subject to
California  law  with respect  to dissenters'  rights. Accordingly,  pursuant to
Chapter 13 of the CGCL, stockholders of Illustra who do not vote in favor of the
Merger and who comply  with the requirements  of the CGCL will  have a right  to
demand payment for, and appraisal of the "fair value" of, their shares. Although
a

                                       34
<PAGE>
dissenting  stockholder may choose to  proceed under one or  both of the states'
statutes, the  dissenting stockholder  must  follow the  appropriate  procedures
under  either the DGCL or  the CGCL or suffer the  termination or waiver of such
rights. See "Applicability of California Law to Illustra."

    DELAWARE APPRAISAL RIGHTS.  If a holder of Illustra Capital Stock  exercises
appraisal  rights in connection  with the Merger  under Section 262  of the DGCL
("Section 262"), any shares of Illustra  Capital Stock in respect of which  such
rights  have been  exercised and perfected  will not be  converted into Informix
Common Stock  but instead  will be  converted  into the  right to  receive  such
consideration  as  may be  determined  by the  Delaware  Court of  Chancery (the
"Court") to be due with respect to such shares pursuant to the laws of the State
of Delaware. This Prospectus/Proxy Statement is being sent by personal  delivery
or  by mail to all holders of record  of shares of Illustra Capital Stock on the
Illustra Record Date and constitutes notice of the appraisal rights available to
such holders under Section 262.

    The following summary of the provisions of Section 262 is not intended to be
a complete statement  of such  provisions and is  qualified in  its entirety  by
reference  to the full text of Section 262,  a copy of which is attached to this
Prospectus/Proxy Statement as Annex B and incorporated herein by reference.

    Holders of shares of Illustra Capital Stock who object to the Merger and who
follow the procedures in Section  262 will be entitled  to have their shares  of
Illustra  Capital Stock  appraised by  the Court and  to receive  payment of the
"fair value" of such shares as of the Effective Time of the Merger.

    A stockholder of Illustra electing to exercise appraisal rights must,  prior
to  the vote concerning the  Merger at the Special  Meeting, perfect his, her or
its appraisal rights by demanding in writing from Illustra the appraisal of his,
her or its shares of Illustra Capital Stock. A vote against the Merger will  not
constitute  a demand for  appraisal. A stockholder electing  to take such action
must do so by a separate written demand as provided in Section 262. A holder who
elects to  exercise appraisal  rights should  mail or  deliver his,  her or  its
written  demand to  Illustra at 1111  Broadway, Suite  2000, Oakland, California
94607. The demand  should specify  the holder's  name and  mailing address,  the
number  of  shares of  Illustra  Capital Stock  owned  and that  such  holder is
demanding appraisal  of  his, her  or  its shares.  Within  ten days  after  the
Effective Time of the Merger, Illustra must provide notice of the Effective Time
of  the Merger to all  stockholders who have complied  with Section 262 and have
not voted in favor of approval and adoption of the Merger Agreement and approval
of the Merger. Only a holder of  record of shares of Illustra Capital Stock  (or
his,  her or its duly appointed  representative) is entitled to assert appraisal
rights for the shares registered in that holder's name.

    Within 120 days after the Effective Time of the Merger, any stockholder  who
has  made a valid written demand and who  has not voted in favor of approval and
adoption of the  Merger Agreement  and approval  of the  Merger may  (i) file  a
petition  in  the Court  demanding a  determination  of the  value of  shares of
Illustra Capital Stock, and (ii) upon  written request, receive from Illustra  a
statement setting forth the aggregate number of shares of Illustra Capital Stock
not voted in favor of approval and adoption of the Merger Agreement and approval
of the Merger and with respect to which demands for appraisal have been received
and  the aggregate  number of  holders of  such shares.  Such statement  must be
mailed within ten days after the  written request therefor has been received  by
Illustra.

    If  a  petition for  an  appraisal is  timely filed,  at  a hearing  on such
petition, the Court is  required to determine the  holders of Dissenting  Shares
entitled to appraisal rights and to determine the "fair value" of the Dissenting
Shares  exclusive of  any element  of value  arising from  the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to  be
paid  upon the value of the Dissenting Shares. In determining such "fair value",
the Court is required to take  into account all relevant factors, including  the
market  value of Illustra Capital Stock and  the net asset and earnings value of
Illustra, and in determining the fair value of interest, the Court may  consider
the rate of interest which Illustra would have had to pay to borrow money during
the pendency of the proceeding. Upon application by a stockholder, the Court may
also order that all or a portion of the expenses

                                       35
<PAGE>
incurred  by  any  stockholder  in  connection  with  the  appraisal proceeding,
including, without  limitation,  reasonable attorneys'  fees  and the  fees  and
expenses  of experts utilized  in the appraisal proceeding,  be charged pro rata
against the  value of  all the  shares  of Illustra  Capital Stock  entitled  to
appraisal.

    Any  holder of  Dissenting Shares who  has duly demanded  an appraisal under
Section 262 will not,  after the Effective  Time of the  Merger, be entitled  to
vote  the shares subject  to such demand for  any purpose or  be entitled to the
payment of dividends or  other distributions on  such Dissenting Shares  (except
dividends  or other distributions payable to stockholders of record as of a date
prior to the Effective Time of the Merger).

    If any holder  of shares  of Illustra  Capital Stock  who demands  appraisal
under  Section 262  effectively withdraws  or loses,  his, her  or its  right to
appraisal, the shares of such holder will  be converted into a right to  receive
that  number of shares of  Informix Common Stock as  is determined in accordance
with the Merger Agreement. A holder will effectively lose his right to appraisal
if he, she or it votes in favor of approval and adoption of the Merger Agreement
and approval of the Merger, or if no petition for appraisal is filed within  120
days  after  the Effective  Time of  the Merger,  or if  the holder  delivers to
Illustra a written withdrawal  of such holder's demand  for an appraisal and  an
acceptance  of the Merger,  except that any  such attempt to  withdraw made more
than 60  days  after the  Effective  Time of  the  Merger requires  the  written
approval  of Illustra.  A holder of  stock represented by  certificates may also
lose his, her or its right  to appraisal if he, she  or it fails to comply  with
the  Court's direction to submit  such certificates of stock  to the Register in
Chancery for notation thereon of the pendency of the appraisal proceedings.

    CALIFORNIA DISSENTERS' RIGHTS.   By virtue of Section  2115 of the CGCL,  if
holders of Illustra Capital Stock exercise dissenters' rights in connection with
the  Merger under Sections 1300-1312 of the CGCL ("Section 1300"), any shares of
Illustra Capital Stock as  to which such dissenters'  rights are exercised  will
not  be converted into the  right to receive shares  of Informix Common Stock by
virtue of the Merger  but instead will  be converted into  the right to  receive
such  consideration  as  may  be  determined to  be  due  with  respect  to such
Dissenting Shares pursuant to the laws of the State of California. The following
summary of the  provisions of  Section 1300  is not  intended to  be a  complete
statement  of such provisions and  is qualified in its  entirety by reference to
the full text of Section 1300, a copy of which is attached hereto as Annex C and
is incorporated herein  by reference.  See "Applicability of  California Law  to
Illustra."

    If  the Merger is approved by  the required vote of Illustra's stockholders,
each holder of shares of  Illustra Capital Stock who does  not vote in favor  of
the  Merger and  who follows the  procedures set  forth in Section  1300 will be
entitled to have shares of Illustra Capital Stock purchased by Illustra for cash
at their fair market value. The fair market value of shares of Illustra  Capital
Stock  will be  determined as of  the day  before the first  announcement of the
terms of  the proposed  Merger, excluding  any appreciation  or depreciation  in
consequence  of the proposed Merger and therefore valuing the shares of Illustra
Capital Stock as if the Merger had not occurred.

    Within ten days  after approval  of the Merger  by Illustra's  stockholders,
Illustra  must mail  a notice  of such approval  (the "Approval  Notice") to all
stockholders who  have  not  voted in  favor  of  the Merger,  together  with  a
statement of the price determined by Illustra to represent the fair market value
of the applicable Dissenting Shares, a brief description of the procedures to be
followed  in order for the stockholder to  pursue dissenters' rights, and a copy
of  Sections  1300-1304  of  the  CGCL.  The  statement  of  price  by  Illustra
constitutes an offer by Illustra to purchase all Dissenting Shares at the stated
amount.

    A  stockholder  of Illustra  electing to  exercise dissenters'  rights must,
within thirty days after the date in which the Approval Notice is mailed to such
stockholder, mail or deliver  the written demand to  Illustra stating that  such
holder  is demanding purchase  of his or  her shares of  Illustra Capital Stock,
stating the number of shares which Illustra must purchase, what the  stockholder
claims  to  be the  fair market  value of  such shares  and enclosing  the share
certificates for endorsement by Illustra.

                                       36
<PAGE>
    If Illustra and the stockholder agree that the shares are Dissenting  Shares
and  agree upon the price  of the shares, Illustra  must pay the stockholder the
agreed upon price plus interest thereon at  the legal rate from the date of  the
agreement on Dissenting Shares within thirty days from the later of (i) the date
of  the  agreement  on  Dissenting  Shares, or  (ii)  the  date  all contractual
conditions to the Merger are satisfied.

    If Illustra denies that the shares are Dissenting Shares, or if Illustra and
the stockholder fail to agree  upon the fair market  value of shares of  capital
stock,  then within six months after the  date the Approval Notice was mailed to
stockholders, any stockholder who has made  a valid written purchase demand  and

               PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
                                  (UNAUDITED)

    The  following unaudited  Pro Forma Combined  Condensed Financial Statements
assume a business combination between Informix  and Illustra accounted for on  a
pooling-of-interests basis and are based on each company's respective historical
consolidated  financial statements and notes thereto, which are included in this
Prospectus/Proxy Statement.  The  Pro  Forma Combined  Condensed  Balance  Sheet
combines  Informix's consolidated condensed balance sheet  as of October 1, 1995
with Illustra's consolidated condensed balance  sheet as of September 30,  1995,
giving  effect to  the Merger  as if  it had  occurred on  October 1,  1995. The
unaudited Pro Forma Combined Condensed  Statements of Income combine  Informix's
historical results for the nine months ended October 1, 1995 and October 2, 1994
and  the  years ended  December  31, 1994  and  1993 with  Illustra's historical
results for the nine months ended September 30, 1995 and 1994, the twelve months
ended December 31, 1994 and  the period from July  31, 1992 (inception) to  June
30, 1993, respectively, giving effect to the Merger as if it had occurred at the
beginning  of the earliest period presented. Since Illustra's inception date was
during its fiscal  year ended June  30, 1993, the  unaudited Pro Forma  Combined
Condensed  Statement of Income for the year  ended December 31, 1992 is the same
as Informix's historical results for such period.

    The pro forma information is presented for illustrative purposes only and is
not necessarily indicative of the  operating results or financial position  that
would  have occurred if the Merger had  been consummated at the beginning of the
earliest period presented, nor is it necessarily indicative of future  operating
results or financial position.

    These  Pro Forma Combined  Condensed Financial Statements  should be read in
conjunction with  the Informix  and Illustra  historical consolidated  financial
statements,  including  the  notes thereto,  included  in  this Prospectus/Proxy
Statement.

1995 and October 2, 1994 and the  fiscal years ended December 31, 1994 and  1993
with  the historical  statements of operations  of Illustra for  the nine months
ended September 30, 1995 and 1994, the twelve months ended December 31, 1994 and
the period from July 31, 1992 (inception) to June 30, 1993, respectively.  Since
Illustra's  inception date was during  its fiscal year ended  June 30, 1993, the
unaudited Pro Forma Combined Statement of Income for the year ended December 31,
1992 is the same as  Informix's historical results for  such period. Due to  the
periods combined as described above, Illustra's net revenues of $152,000 and net
loss  of $2,011,000  for the period  July 1, 1993  to December 31,  1993 are not
included in the Pro Forma Combined Condensed Statements of Income.

NOTE 2.  BASIS OF PRESENTATION

    PRO FORMA OUTSTANDING INFORMIX COMMON STOCK

    The maximum number of shares  of Informix Common Stock  to be issued in  the
Merger  (including  Informix  Common  Stock to  be  reserved  for  issuance upon
exercise of  Illustra's options  and  warrants to  be  assumed by  Informix)  in
exchange  for the  acquisition by Informix  of all  outstanding Illustra Capital
Stock and all outstanding options and warrants to acquire Illustra Capital Stock
will be 15,000,000 shares. Consequently,  the Common Exchange Ratio will  depend
on  the  capitalization of  Illustra at  the Effective  Time. Assuming  that all
shares of Illustra Preferred  Stock are converted to  shares of Illustra  Common
Stock  prior to the Effective Time, and further assuming that the capitalization
of Illustra at  the Effective Time  is in  all other respects  identical to  the
capitalization  as of  September 30,  1995, the  Common Exchange  Ratio would be
0.82685 of  a share  of Informix  Common  Stock for  each outstanding  share  of
Illustra  Common Stock. Such Common Exchange Ratio was used in preparing the pro
forma combined financial  data and the  following table which  provides the  pro
forma share issuance in connection with the Merger:

    The actual number of shares of Informix Common Stock to be exchanged for all
of  the outstanding  Illustra Common Stock  will be determined  at the Effective
Time based on the capitalization of Illustra at the Effective Time.

    MERGER-RELATED EXPENSES

   
    Informix and Illustra estimate that they will incur Merger-related expenses,
consisting  primarily  of  transaction   costs  for  investment  bankers   fees,
attorneys, accountants, financial printing and other
    

                                       44

     NOTES TO PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS (CONTINUED)
                                  (UNAUDITED)
   
related charges, of approximately $6.0 million. This estimate is preliminary and
is  therefore subject to change. These  nonrecurring expenses will be charged to
operations in the fiscal quarter in which the Merger is consummated.
    

    The Pro Forma Condensed Combined Balance Sheet gives effect to such expenses
as if they had been incurred as of  October 1, 1995, but the Pro Forma  Combined
Condensed Statements of Income do not give effect to such expenses.

    PRO FORMA ADJUSTMENTS

    Since  Informix plans  to file consolidated  tax returns  which will include
Illustra's operations subsequent  to the Effective  Time, pro forma  adjustments
were made to reduce the valuation allowances previously provided by Illustra for
Illustra's  net  deferred tax  assets  related primarily  to  loss carryforwards
generated since  its  inception  in  July 1992.  Informix  has  determined  that
estimated  combined future taxable  income is sufficient to  conclude that it is
more likely than not that such net  deferred tax assets could be realized. As  a
result,  the Pro Forma Combined Condensed Financial Statements include pro forma
adjustments  which  reduced  income  tax  expense  by  $3,752,000,   $2,354,000,
$3,160,000  and  $314,000 for  the the  nine  months ended  October 1,  1995 and
October 2, 1994 and  the years ended December  31, 1994 and 1993,  respectively,
and  increased net deferred tax  assets by $7,991,000 at  October 1, 1995. Other
than for the Merger-related expenses as described above, there were no other pro
forma adjustments.

    CONFORMING ADJUSTMENTS

    No adjustments were required to conform the accounting policies of  Illustra
and  Informix. Certain amounts for Illustra have been reclassified to conform to
Informix's financial statements presentation.

NOTE 3.  PRO FORMA NET INCOME PER SHARE

    The pro  forma  combined net  income  per share  is  based on  the  combined
weighted average number of common and dilutive common stock equivalent shares of
Informix  Common Stock and  Illustra Common Stock and  assumes conversion of all
outstanding Illustra Preferred  Stock at  the beginning of  the earliest  period
presented  and further assumes a Common Exchange  Ratio as of September 30, 1995
of 0.82685 of a  share of Informix  Common Stock for  each outstanding share  of
Illustra  Common Stock  and the  issuance of  174,557 shares  of Informix Common
Stock in satisfaction of certain rights retained by the former holders of Series
C Preferred Stock upon conversion of Series C Preferred Stock to Illustra Common
Stock. The actual number of shares of Informix Common Stock to be exchanged  for
all of the outstanding Illustra Common Stock will be determined at the Effective
Time based on the capitalization of Illustra at the Effective Time.

    Share and per share information applicable to prior periods for Informix has
been  restated to reflect a  two-for-one stock split (effected  in the form of a
stock dividend) which was effective on June 26, 1995.

                               INFORMIX BUSINESS

BACKGROUND

    Informix designs, develops, manufactures,  markets and supports  distributed
relational   database  management   systems,  object-oriented,   graphical-  and
character-based application development  tools and  graphical data-access  tools
for delivering information to most significant desktop platforms. In addition to
software  products, Informix offers training,  consulting and maintenance to its
customers. Informix was  initially incorporated  in California in  1980 and  was
reincorporated   in  Delaware  in  August  1986.  Unless  the  context  requires
otherwise,  the  term  "Informix"  refers   to  Informix  Corporation  and   its
subsidiaries.

   
    Informix  designs,  develops,  manufactures, markets  and  supports database
management  systems,  connectivity  interfaces  and  gateways  and   application
development  tools for graphical- and  character-based software applications all
as part of relational database management systems ("RDBMS"). All of the Informix
database  products  developed  since  1983  support  Structured  Query  Language
("SQL"),  an  industry  standard  created by  IBM.  Informix  believes  that its
INFORMIX-4GL Product,  introduced  in  1986,  was  the  first  fourth-generation
applications  development  language  consolidating  SQL  with  syntax  for  menu
creation, formatted screen  generation and  report writing.  The combination  of
these  features significantly increases  programmer productivity and flexibility
in  developing  applications  software.  Informix's  core  database   management
software  runs on the UNIX-Registered Trademark-, Windows-TM- and Windows/NT-TM-
operating systems,  and certain  networks composed  of computers  running  these
operating systems.
    

    Informix's  customers consist primarily of end-users, application resellers,
computer original equipment  manufacturers ("OEMs")  and distributors.  Informix
markets  its  products  directly  to  end-users  through  its  sales  force  and
indirectly to end-users through application resellers, OEMs and distributors.

   
    In 1995, Informix  had three  internal sales  organizations: North  America;
Europe,  Middle East and Africa; and  the Intercontinental Group, which included
Japan and the Asia/Pacific and Latin America regions. Effective January 1, 1996,
these sales organizations were reorganized into the following groups:  Americas,
including  the North America and Latin America regions; International, including
the Europe,  Middle  East,  Africa  and Asia/Pacific  regions;  and  Japan.  The
Americas  sales  organization is  headquartered in  Menlo Park,  California, has
sales offices located in  major cities throughout the  United States and  Canada
and  in  7  Latin  American  countries.  The  International  sales organization,
headquartered in the United Kingdom, has sales offices in 29 countries. Informix
also has a European development,  production and distribution center located  in
Ireland. The Japan sales organization is headquartered in Tokyo, Japan. Informix
has operating subsidiaries in 36 foreign countries.
    

PRODUCTS

    DATABASE ENGINES

    Informix offers the following relational database SQL engines, which share a
common set of development tools:

    - INFORMIX-OnLine,   Informix's   first   generation   on-line   transaction
      processing ("OLTP")  database  server with  stored  procedures,  triggers,
      referential  integrity,  high availability,  document imaging  support and
      fast response times in heavy transaction environments.

    - INFORMIX-OnLine Dynamic  Server-TM-,  Informix's  second  generation  OLTP
      engine.  This server is based  on Informix's Dynamic Scalable Architecture
      and  features  parallel  data   processing  capability,  replication   and
      connectivity  options built into the  core database server, offering users
      significant enhancements without adding  additional cost. This product  is
      available on uniprocessor and symmetric multiprocessing systems.

      product family is comprised of three core products: INFORMIX-4GL Compiled,
      INFORMIX-4GL  Rapid  Development   System  and  INFORMIX-4GL   Interactive
      Debugger.

    - INFORMIX-SQL,   a  package   of  five   interactive  tools   for  creating
      character-based applications. INFORMIX-SQL consists of a forms package,  a
      report   writer,  an  interactive  SQL  editor,  a  menu  builder  and  an
      interactive schema editor.

    - C-ISAM-Registered Trademark-, a library of C functions that manage indexed
      sequential access method files. C-ISAM bypasses the overhead of an  entire
      database  management system and  allows direct access  to an application's
      records.

    - INFORMIX-NewEra ViewPoint-TM-, a graphical database access and  analytical
      tool  specifically designed to give non-technical computer users point and
      click  access  to  information  contained  in  corporate  or  departmental
      databases and to run their own customized forms and reports.

    - INFORMIX-NewEra  ViewPoint Pro, a  graphical database administration tool,
      includes all of the  features of INFORMIX-NewEra ViewPoint,  as well as  a
      database  schema builder,  a SQL editor  and a  SuperView-TM- builder, for
      creating highly specialized  views to the  database that simplify  access,
      retrieval and analysis of data.

    - INFORMIX-MetaCube-TM-,  a  high-performance on-line  analytical processing
      engine  that   automatically   preconsolidates   data   and   provides   a
      multidimensional view of data without the constraints of a two dimensional
      (row  and  table) data  model. The  INFORMIX-MetaCube product  family also
      includes MetaCube Explorer, an adhoc decision support tool for end  users,
      MetaCube  Warehouse  Manager,  a  graphical  tool  for  administering  the
      "metadata"  describing  a  database  in  a  logical,  user-friendly  view,
      MetaCube  Agents, a scheduler  to perform user  queries and administrative
      tasks on a database in the  background, and MetaCube for Excel, an  add-in
      to  the standard Microsoft spreadsheet  environment. The MetaCube products
      became available in the fourth quarter  of 1995 as a result of  Informix's
      acquisition of Stanford Technology Group, Inc.

    In  February  1995,  Informix  entered  into  an  agreement  with Investment
Intelligence Systems  Limited  ("IISL")  which gave  IISL  exclusive  rights  to
develop, distribute, sell and support the

                                       47
<PAGE>
INFORMIX-Wingz-Registered Trademark- spreadsheet and the
INFORMIX-HyperScript-Registered    Trademark-   Tools    graphical   development
environment to new and existing customers. IISL assumed full responsibility  for
both  products effective  June 30, 1995.  The agreement is  world-wide, with the
exception of  Japan, where  ASCII Corporation  retains the  exclusive rights  to
market and distribute the Kanji version of INFORMIX-Wingz.

   
    In October 1995, Informix acquired Stanford Technology Group, Inc., a United
States   based  provider  of  on-line   analytical  processing  technology,  for
approximately 570,000 shares of Informix  common stock. The transaction will  be
accounted  for  as a  pooling of  interests.  As a  result of  this acquisition,
Informix added the INFORMIX-MetaCube product family to its product line.
    

    CONNECTIVITY PRODUCTS

    The Informix connectivity products are:

    - INFORMIX-Gateway-TM- with DRDA,  a UNIX-based  connectivity tool  allowing
      interoperability  to IBM  databases such as  DB2, DB2/VM  and DB2/400 from

                                       48

MARKETING AND CUSTOMERS

    In 1995, Informix  had three  internal sales  organizations: North  America;
Europe,  Middle East and Africa; and  the Intercontinental Group, which included
Japan and the Asia/Pacific and Latin America regions. Effective January 1, 1996,
these sales organizations were reorganized into the following groups:  Americas,
including  the North America and Latin America regions; International, including
the Europe, Middle East, Africa and Asia/Pacific regions; and Japan.

    In North America, Informix distributes its products through the channels  of
direct  end-user  licensing,  OEMs,  application  resellers  addressing specific
markets and distributors. Informix licenses its products to large companies  and
government  entities through  its direct  sales force,  and to  certain of these
companies, as well as smaller end-users, through its telemarketing sales force.

    In Europe,  Latin America  and Japan,  Informix uses  distribution  channels
similar in type to those used by Informix in the United States. In other foreign
regions,   Informix  licenses  its  products   to  end-users  primarily  through
application resellers, distributors and OEMs.

    Informix has chosen  a multiple  channel distribution  strategy to  maintain
broad  market  coverage  and  product  availability.  Informix,  therefore,  has
generally avoided exclusive relationships with its licensees and other resellers
of its products. Discount policies and reseller licensing programs are  intended
to support each distribution channel with a minimum of channel conflict.

   
    At  December 31, 1995, Informix's sales, marketing and support staff totaled
1,011 regular employees in  the North America region;  103 regular employees  in
the  Latin America region, 652 regular employees  in the Europe, Middle East and
Africa regions, 231 regular employees in the Asia/ Pacific region and 77 regular
employees in Japan.
    

    In January 1995,  Informix acquired a  90 percent interest  in the  database
division  of ASCII Corporation, a distributor of its products in Japan. Informix
acquired the remaining 10 percent interest in January 1996. This acquisition has
been  recorded  as  a  purchase.  The   purchase  cost  of  this  business   was
approximately  $46,000,000. Additionally, in April 1995, Informix acquired an 80
percent interest in the database division of Daou Corporation, a distributor  of
its  products in Korea. Informix will  acquire the remaining 20 percent interest
in January  1997. This  acquisition has  been recorded  as a  purchase with  the
purchase cost of this business being approximately $4,300,000.

    Informix  provides a  financing option to  customers in  connection with the
license of software in  the United States  through its wholly-owned  subsidiary,
Informix Credit Company. Similar financing is offered in Europe.

LICENSING

    END-USER LICENSING

    Informix's  products are  licensed directly to  end-users through Informix's
sales force as well  as indirectly to  end-users through application  resellers,
OEMs  and distributors. Informix believes that the common core technology of its
RDBMS software  products,  based  on  standard operating  systems  and  the  SQL
database language places it in a strong position to sell into major corporations
and  government  agencies  that  wish  to  standardize  their  diverse computing
environments. As a result, certain of these end-user organizations have  entered
into general purchasing agreements with Informix which offer volume discounts.

    APPLICATION RESELLER LICENSING

    Since   its  inception,  Informix  has  licensed  application  resellers  to
distribute its products. A typical application reseller develops an  application
product  (e.g., an insurance  agency management system)  using one of Informix's
products and then licenses the  resultant application software to its  customers
in  the target market. The application reseller customer purchases a license for
use of Informix's product to develop  an applications program. Depending on  the
application program developed, it may include a run-only license, a full version
license or even multiple product licenses.

                                       49
<PAGE>
    Application resellers develop applications using a wide array of application
development  tools, including  products from Informix,  such as INFORMIX-NewEra,
INFORMIX-4GL and INFORMIX-SQL,  as well  as products offered  by third  parties.
Applications  developed using Informix's products  are generally portable across
various brands of computers and  different operating systems. Informix  believes
that this feature is significant to this distribution channel.

    Informix  has  specialized  programs  to  support  the  application reseller
distribution channel.  Under  these  programs,  Informix  provides  to  selected
application   resellers  a   combination  of   marketing  development  services,
consulting and technical marketing support and discounts.

    OEM LICENSING

    Informix's products  are also  marketed  with the  assistance of  the  sales
forces  of its  OEM customers  who have concluded  that "solution  selling" of a
combination of software and hardware to their respective customers enhances  the
sales  of their computer equipment. Informix believes that the compatibility and
range of  applications for  its  products is  significant to  this  distribution
channel.

    DISTRIBUTOR LICENSING

    Informix   has  established   a  network   of  full   service  international
distributors who  provide  local service  and  support, as  well  as  Informix's
products,  to their respective  national markets. Informix's  products have been
translated by  Informix or  Informix's  distributors into  a number  of  foreign
languages,  including  Japanese (Kanji),  Chinese (Simplified  and Traditional),
Czech, Danish,  French, German,  Hebrew,  Hungarian, Korean  (Hangul),  Italian,
Polish, Russian, Slovak, Spanish, Swedish and Thai.

PRODUCT DEVELOPMENT

    The  computer software industry is  highly competitive and rapidly changing.
Consequently,  Informix  dedicates  considerable   resources  to  research   and
development  efforts to  enhance its  existing product  line and  to develop new
products to  meet  new  market opportunities.  Major  research  and  development
projects  in 1995 included  new releases of  INFORMIX-NewEra and INFORMIX-OnLine
Dynamic Server and the release of INFORMIX-OnLine Extended Parallel Server on  a
limited basis.

    Most  of Informix's current software products and accompanying documentation
have been developed internally; however, Informix has acquired certain  software
products from others and plans to do so again in the future.

    Current product development is focused toward:

    - Improvement  and enhancement  of current  products and  new products, with
      particular emphasis on parallel computer architecture, graphical desk top,
      system administration, application  partitioning, mobile capabilities  and
      support  for complex data,  such as audio,  video, text and  images of the
      type often used in World Wide Web or other Internet-based applications.

    - Improvements to Informix products to provide greater speed and support for

COMPETITION

    Informix  faces  intense  competition  in  the  market  for  RDBMS  software
products.  Companies  in the  RDBMS  market compete  primarily  on the  basis of
price/performance characteristics,  name  recognition,  and  technical  support,
training and consulting services.

    With  respect  to RDBMS  performance, Informix  believes that  the principal
competitive factors include:

    - Application development productivity  (the speed  with which  applications
      can be built).

    - Database  performance (the speed  at which database  storage and retrieval
      functions are executed).

    - The ability to support large warehouses of information.

    - Reliability, availability and serviceability.

    - The distribution of RDBMS software  applications and data across  networks
      of computers from multiple suppliers.

    - Increasingly,  the ability to  manage complex data  and solve more complex
      business problems based on such data.

    Informix believes  that  the  technical  advantages  of  its  products,  its
approach  to sales and marketing, its relations with application resellers, OEMs
and distributors and its customer service and support contribute to its  ability
to compete favorably in this market.

   
    The  chief competition  faced by  Informix is  currently provided  by Oracle
Corporation, Sybase,  Inc.,  CA  Ingres (a  subsidiary  of  Computer  Associates
International,  Inc.),  IBM  Corporation, Microsoft  Corporation  and  Red Brick
Systems, Inc. and  suppliers of  third party  tools such  as Gupta  Corporation,
Forte Software, Inc. and Dynasty Technologies, Inc. Informix believes that there
is a large market for RDBMS software which might attract additional competitors.
Additionally,   some  of  Informix's  current  competitors  and  many  potential
competitors have  greater  financial,  technical and  marketing  resources  than
Informix.
    

    To  the  extent  that  market  acceptance  for  personal  computer  oriented
technologies increases at the  expense of UNIX or  other non-PC platforms,  this
could  result  in  greater  price pressure  on  certain  of  Informix's database
products and  services.  The availability  and  market acceptance  of  Microsoft
Corporation's  Windows NT operating system may increase the competition faced by
the principal operating  system platforms on  which Informix's products  operate
and  may  result in  greater price  pressure on  certain of  Informix's database
products and services. Also, new or enhanced products introduced by existing  or
future competitors could have an adverse effect on Informix's business. Existing
and  future competition  or changes  in Informix's  product or  services pricing
structure or product or service offerings could result in an immediate reduction
in the prices  of Informix's products  or services.  If this were  to result  in
significant  price  declines,  the  effects  of which  were  not  offset  by any
resulting  increases  in  sales  volume  of  Informix's  products  or  services,
Informix's  business,  results of  operations and  financial condition  would be
adversely affected.

PRODUCT PROTECTION

    Informix relies on a  combination of trade  secret, copyright and  trademark
laws,  license agreements  and technical measures  to protect its  rights in its
software products.  Like many  software companies,  Informix has  no patents  to
date,  although it  has applied  for four  software patents  for core technology
present in Informix products,  and is proceeding  with applications for  several
other   software  patents.   Informix  maintains  trademark   and  service  mark
registrations in the United States and numerous other foreign jurisdictions.

    Informix's products are generally licensed to end-users on a  "right-to-use"
basis  pursuant  to a  license that  restricts the  use of  the products  to the
customer's internal business purposes  either on a single  computer at a  single
site  or to  a specific  number of users  at a  single site  or enterprise wide.

                                       51
<PAGE>
Informix also relies on "shrink-wrap" licenses. Informix's "shrink-wrap" license
includes a prominently displayed notice informing the end-user that, by  opening
the  product packaging,  the end-user agrees  to be bound  by Informix's license
agreement printed  on the  package. Copyright  and trade  secret protection  for
source  and  object code  version  of software  products  may be  unavailable in
certain foreign countries. In addition, "shrink-wrap" licenses may be wholly  or
partially unenforceable under the laws of certain jurisdictions.

    Informix protects the human readable, source code version of its products as
a  trade secret and  an unpublished copyrighted work.  Informix has licensed the
source code of its  products to certain  customers under certain  circumstances,
and  for restricted  uses. In  addition, Informix  has entered  into source code
escrow agreements with a number of its customers that generally require  release
of  source code to  the customer in the  event there is  a bankruptcy or similar
proceeding by or against  Informix, Informix ceases to  do business or  Informix
ceases to support the product. In the event of a release of the source code to a
customer,  the  customer is  required to  maintain  its confidentiality  and, in
general, to use the source code solely for internal business purposes or for the
purpose of providing maintenance and support  to its customers, and, in  certain
circumstances, to embedding it in customer products.

    Informix believes that, because of the rapid pace of technological change in
the  computer software industry,  patent, trade secret  and copyright protection
are less significant than factors such as the knowledge, ability and  experience
of Informix's personnel, new product introduction, frequent product enhancement,
name recognition and ongoing product maintenance.

EMPLOYEES
   
    As  of December  31, 1995, Informix  and its subsidiaries  had 3,219 regular
employees worldwide, including  2,074 in  sales, marketing and  support; 644  in
research  and  development;  90  in operations  and  411  in  administration and
finance.
    

    Competition in recruiting  personnel in  the computer  software industry  is
intense.  Informix believes that its  future success will depend  in part on its
continued ability to recruit and retain highly skilled management, marketing and
technical personnel.

    None of Informix's U.S. employees are represented by a labor union. A  small
number  of employees  located outside  of the  United States  are represented by
labor unions. The degree of this representation varies from country to  country.
Informix  has  experienced  no work  stoppages  and believes  that  its employee
relations are excellent.

PROPERTIES
   
    Informix's  headquarters  and  its   marketing,  finance,  Americas   sales,
administration,  customer service  and research  and development  operations are
located in five modern buildings in a seven building office park in Menlo  Park,
California,  approximately  30 miles  south  of San  Francisco.  Informix leases
approximately 214,000 square feet  of space in these  buildings. The leases  for
spaces in three of the buildings expire in March 1998. Informix has an option to
renew  each lease  for another  five year term  at 95%  of the  then fair rental
value. The remaining leases expire in September 2001.
    

    Some of  the  research and  development  for Informix's  tools  products,  a
portion  of  Informix's  customer  service  organization,  Informix's  principal
manufacturing facility and Informix's telemarketing organization are located  in
two  modern buildings aggregating  approximately 135,000 square  feet in Lenexa,
Kansas, a suburb of Kansas  City. The buildings are  owned by a partnership,  of
which Informix Software, Inc. is a 50% partner, and leased by the partnership to
Informix Software, Inc. under a lease with an initial ten-year term that expires
in  March 1998. There are two five-year renewal options. Rental under this lease
remains fixed through 1998, and then adjusts to prevailing rates for the renewal
terms.

   
    Informix also  leases office  space in  approximately 45  facilities in  the
United States and Canada and approximately 58 facilities internationally.
    

    Informix believes that its facilities are adequate for its current needs and
that  suitable additional  or substitute  space will  be available  as needed to
accommodate the expansion of Informix's operations.

</TABLE>

    Informix's operating income in the first nine months of 1995 was 21  percent
of net revenues, compared to 20 percent in the corresponding period in 1994.

    Although  Informix's operating margins  have exceeded or  equaled 20 percent
over the last several quarters, Informix's expenses are relatively fixed in  the
near  term and unexpected variances in  planned revenues, which are difficult to
forecast, can  result  in  variations  in operating  margins  and  cost  ratios.
Informix's  quarterly operating margins  have generally followed  a pattern with
second half revenues and operating margins generally being higher than those  of
the  preceding first half;  however, there is no  assurance that this historical
pattern will be repeated.

    Informix derives  revenues  principally  from  licensing  its  software  and
providing  technical product support and  updates to customers. License revenues
may involve the shipment of product by Informix

                                       53
<PAGE>
or the granting of  a license to manufacture  products. Informix's products  are
sold directly to end-user customers or through resellers, including OEMs, system
integrators, distributors, or application vendors. Informix's revenues have been
increasingly  derived from sales contracts directly with end-users and less from
the distributor or  OEM sales channels.  These end-user sales  contracts can  be
relatively large in size and are difficult to forecast both in timing and dollar
value.  In addition,  these revenue  contracts have  relatively lower associated
software distribution  and  selling  costs.  From  time  to  time  Informix  has
recognized substantial net revenue from these large software license agreements.
These  transactions, which are difficult to predict, have caused fluctuations in
net revenues and in net  income because of the  relatively high gross margin  on
such  revenues.  Informix  expects  that transactions  of  this  nature  and the
resulting fluctuations will continue.

    Throughout the remainder of 1995, Informix  will continue to invest more  in
customer  services, marketing and  research and development,  and make personnel
additions to Informix's  sales force  worldwide. These  additional expenses  may
adversely affect Informix's operating margins in 1995 if there are no offsetting
increases in revenues or reductions in other operating expenses.

    As  the number  of software  products and  software patents  in the industry
increases, Informix believes  that software developers  may become  increasingly
subject  to infringement claims.  There can be  no assurance that  a third party
will not assert  that its patents  or other proprietary  rights are violated  by
products  offered by Informix.  Any such claims,  with or without  merit, can be
time consuming  and expensive  to defend  and could  have an  adverse effect  on
Informix's business, results of operations, financial position and cash flows.

    Informix's   stock  price   may  be   subject  to   significant  volatility,
particularly on a  quarterly basis. Any  shortfall in revenue  or earnings  from
levels  expected by  securities analysts or  others could have  an immediate and
significant adverse effect on  the trading price of  Informix's common stock  in
any given period. Additionally, as is common in the industry, a disproportionate
amount  of Informix's license revenue is derived from transactions that close in
the last  few weeks  of a  quarter  that make  quarterly revenues  difficult  to
forecast.  Informix may not learn of, or be able to confirm, revenue or earnings
shortfalls until the end  of each quarter,  which could result  in an even  more
immediate  and adverse effect  on the trading price  of Informix's common stock.
Finally, Informix participates in a highly dynamic industry, which often results
in significant volatility of Informix's common stock price.

</TABLE>

    The increase  in  service  revenue,  which  consists  of  customer  support,
training  and consulting, was primarily attributable  to the continued growth of
the installed customer base, the renewal of maintenance contracts and  increased
consulting revenue. Informix continues to emphasize support services as a source
of revenue.

    The  revenue  growth in  the first  nine months  of 1995  primarily reflects
continued strong worldwide acceptance for Informix's new and existing technology
and products. Although  Informix expects revenues  to grow in  the remainder  of
1995, there can be no assurance that such growth will be achieved or that growth
rates  in the  future will be  comparable to those  in the first  nine months of

                                       54
<PAGE>
1995. Informix's revenues, along  with those of the  RDBMS industry as a  whole,
have  shown substantial  growth over  the last  several years.  The industry has
benefited from trends to  downsize from large  proprietary computer systems  and
market acceptance of UNIX and other open operating environments.

    Informix  has focused on  the UNIX, open operating  system market since 1980
and has broadened its  open environments by releasing  a Windows and  Windows/NT
version  of an Informix database server in 1994. Informix has also developed and
released connectivity products  to allow access  to other relational  databases,
both  proprietary and  open, and access  to this data  through various protocols
such as IBM's DRDA and X/Open's XA. The industry movement to new open  operating
systems  like Windows/NT and access through  low-end, desktop machines may cause
downward pressure on prices of database  and related products. If such  downward
pressure on prices were to occur, margins would be adversely affected.

    The  license  revenue  growth in  the  first  nine months  of  1995 reflects
continued strong demand for Informix's products, particularly for Informix's new
generation of database servers, INFORMIX-OnLine DynamicServer-TM-. Informix  has
also  started to see revenue  growth in the tools  area with the introduction of
INFORMIX-NewEra-TM-, a  third-generation client/server  application  development
tool  which became available in the second  half of 1994. During the nine months
of 1995,  Informix  introduced, on  a  limited basis,  INFORMIX-OnLine  Extended
Parallel  Server ("XPS"), a new high-performance, scalable database server based
on  Informix's  Dynamic  Scalable  Architecture  ("DSA")  and  also   introduced
INFORMIX-NewEra-TM- 2.X on the Windows platform.

    Informix's  ability to sustain growth depends  in part on the timely release
of successful  new and  updated products,  and the  success of  new and  updated
products  from its competitors.  Informix has experienced  product delays in the
past and may have delays in the future.

    A key factor in determining the success of Informix will continue to be  the
ability  of Informix's products  to interoperate and  perform well with existing
and future leading, industry standard application software products intended  to
be   used  in  connection  with  RDBMS.  Failure  to  meet  existing  or  future
interoperability and  performance requirements  of certain  independent  vendors
marketing such applications in a timely manner could adversely affect the market
for Informix's products.

    Over  half of  Informix's net  revenues are  derived from  its international
operations. In  Europe and  Asia/Pacific,  most revenues  and expenses  are  now
denominated  in local  currencies. The  U.S. dollar  weakened in  the first nine
months of 1995 against  the major European  and Asian/Pacific currencies,  which
resulted  in  higher revenue  and expenses  recorded  when translated  into U.S.
dollars and compared with  the prior year periods.  Through 1994, most  revenues
from  Asia Pacific, Canada  and Latin America were  denominated in U.S. dollars.
Accordingly, the translation of the revenues for these regions was less impacted
by fluctuations in  foreign exchange  rates. Informix has  increased its  direct
sales  presence in  Asia/Pacific by  opening offices  and acquiring  its primary
software distributors in Malaysia  in 1994, and Japan  and Korea in early  1995.
This  increased the proportion of direct  sales denominated in local currency in
these regions. Informix has also increased its direct presence in Latin America,
although a significant percentage  of the revenue is  still denominated in  U.S.
dollars. In the future, Informix expects currency fluctuations in Mexico, and to
a  lesser  extent,  other  Latin  American  countries  to  continue.  Informix's
operating and pricing  strategies take  into account changes  in exchange  rates
over  time;  however,  Informix's  results of  operations  may  be significantly
affected in the short term by fluctuations in foreign currency exchange rates.

    Informix has a hedging program in  place to minimize foreign exchange  gains
or  losses,  where  possible,  from  recorded  foreign  denominated transactions
resulting from fluctuations in exchange rates. This program involves the use  of
forward foreign exchange contracts in the primary European and Asian currencies.
Informix  has  limited  unhedged  transaction  exposures  in  certain  secondary
currencies in Latin America, Eastern Europe, and Asia/Pacific because there  are
limited forward currency exchange markets in these currencies. Informix does not
attempt to hedge the translation to U.S. dollars of foreign denominated revenues
and expenses not yet incurred.

    Informix's  distribution markets  are organized into  three general markets:
North America;  Europe,  the  Middle East,  and  Africa;  and  Intercontinental,
consisting  of Latin America and the Asia/ Pacific region. During the first nine
months of 1995, these  organizations contributed 42 percent,  38 percent and  20
percent,  respectively, of  Informix's net revenues  compared to  44 percent, 40
percent, and 16 percent, respectively, for the same period in 1994.

    Software distribution  costs  consist  primarily of:  1)  manufacturing  and
related  costs  such as  media, documentation,  product assembly  and purchasing
costs, customs,  freight  and third  party  royalties; and  2)  amortization  of
previously capitalized software development costs.

    The increase in the amortization of capitalized software in absolute dollars
in  the first nine months of 1995 compared to the same period in 1994 was due to
the release of several products in the latter half of 1994 and the first half of
1995. Informix expects  that amortization  of capitalized  software in  absolute
dollars will continue to increase in the future as new products are released.

    Manufactured cost of software distribution in the first nine months of 1995,
as  a percentage of license revenues, remained  flat compared to the same period
in 1994. The cost of software  distribution as a percentage of license  revenues
may  vary depending upon whether the product is reproduced by Informix or by its
customers.

</TABLE>

    The increase in  sales and marketing  expenses in the  first nine months  of

increased sales headcount worldwide, new  sales offices and increased  marketing
programs associated with new product introductions.

<PAGE>
    With  the continuing expansion  throughout 1995 of  worldwide operations, as
well as increased sales and marketing expenditures in 1995 aimed at  positioning
Informix  and its new and existing products in the marketplace, Informix expects
that sales and marketing expenses for the remainder of 1995, as a percentage  of
net revenues, will be similar to those of the first nine months of 1995.

    RESEARCH AND DEVELOPMENT EXPENSES

    Informix  accounts  for its  product  development costs  in  accordance with
Statements of Financial  Accounting Standards  No. 86 (FAS  86). This  statement
requires  that once technological  feasibility of a  developing product has been
established, all  subsequent costs  incurred  in developing  that product  to  a
commercially  acceptable  level be  capitalized and  amortized ratably  over the
revenue life  of  the  product. Informix's  research  and  development  expenses
exclude  capitalized software  costs of  $12.7 million  and $9.7  million in the
first nine months of 1995 and 1994, respectively, and exclude amortization costs
of previously capitalized software. The following table summarizes research  and
product  development costs for the periods ended  October 1, 1995 and October 2,
1994:

</TABLE>

    The increase in research and development expenditures in absolute dollars in
the first  nine months  of 1995  compared to  the corresponding  period in  1994
resulted  from  an  increase  in  staff  working  on  new  products  and product
extensions.

    The  higher  capitalization  in  absolute  dollars  of  product  development
expenditures  in the first  nine months of  1995 compared to  the same period in
1994 resulted  from  an increase  in  the  work involved  in  projects  reaching
technological  feasibility as they neared  their release dates. Informix expects
the proportion  of work  on  capitalized projects  to remain  relatively  stable
throughout the remainder of 1995.

    Major  new programs currently under development include the expansion of the
DSA family  of servers  and  connectivity products  and subsequent  versions  of
Informix's graphical object-oriented tool INFORMIX-NewEra-TM-. Informix believes
that  research  and development  expenditures are  essential to  maintaining its
competitive position in its primary  markets and expects the expenditure  levels
to increase in absolute dollars.

    General  and  administrative  expenses for  the  first nine  months  of 1995
remained relatively  flat  as a  percentage  of  net revenues  compared  to  the
corresponding  period in 1994. Informix  expects that general and administrative
expenses as a  percentage of  net revenues  for the  remainder of  1995 will  be
consistent with those of the first nine months of 1995.

    PROVISION FOR INCOME TAXES

    Informix's  effective tax rate increased to 37.5 percent of pretax income in
the first nine months of 1995 from 36.0 percent in the same period in 1994.  The
higher effective tax rate for the first nine months of 1995 was primarily due to
the expiration of the U.S. federal research and development tax credit in 1995.

    Informix  anticipates its fiscal 1995 effective tax rate to be approximately
37.5 percent;  however,  this  rate  could  change based  on  a  change  in  the
geographic  mix of Informix's earnings and  the amount of permanent reinvestment
offshore of  a portion  of the  1995 earnings  of Informix's  lower-taxed  Irish
operations  and the  potential reinstatement  of the  U.S. federal  research and
development tax credit.

    IMPACT OF INFLATION

    The effect  of  inflation on  Informix's  financial position  has  not  been
significant.

RESULTS OF OPERATIONS -- FISCAL YEAR COMPARISON

    Selected elements of Informix's financial statements are shown below for the
last three years as a percentage of net revenues and as a percentage change from
year to year.

    In  1991,  Informix was  selected  to provide  the  database component  of a
decision-support system for the Army National Guard and Army Reserves. In  1992,
Informix  received $26.8  million as part  of this  Reserve Component Automation
System ("RCAS")  contract and  recorded  $21.8 million  as license  revenue  and
incurred  $3.2 million in related operating expenses. The remaining $5.0 million
of service  revenue  is being  recognized  over  the support  period.  In  1992,
Informix  also  recorded  a  $10.5  million charge  due  to  a  settlement  of a
securities class  action  lawsuit  (see  Litigation  Settlement).  In  providing
comparative information, corresponding tables are presented with Table 1 showing
1992  amounts as reported and  Table 2 showing 1992  pro forma amounts excluding
the RCAS  license revenue  and related  expenses and  the litigation  settlement
charge. Informix believes that year-to-year comparisons of financial results are
not necessarily indicative of future results.

    Informix's  operating income in 1994 was 22 percent of net revenues compared
to 24 percent in  1993 and 26  percent in 1992. Excluding  the revenue from  the
RCAS contract and associated expenses, 1992 operating income was 21 percent. The
decrease  in operating  margin in  1994 compared  to 1993  was primarily  due to
extensive  investment  in   customer  services,  marketing   and  research   and
development  expenditures  and  personnel additions  to  Informix's  sales force
worldwide.

* Excludes RCAS license revenue in 1992.

    Service revenue, consisting of  customer support, training, and  consulting,
increased  in  each  of  the years  presented.  These  increases  were primarily
attributable to the  continued growth  of the  installed customer  base and  the
renewal  of  maintenance  contracts.  Informix  continues  to  emphasize support
services as a source of revenue.

    The revenue growth  in 1994  primarily reflects  continued strong  worldwide
acceptance  for  Informix's  new and  existing  technology. The  growth  in 1993
reflects Informix's  continued emphasis  on increasing  license volume  for  its
database  servers  and connectivity  products.  Informix's revenues,  along with
those of the RDBMS industry as a  whole, have shown substantial growth over  the
last  several years.  The industry has  benefitted from trends  to downsize from
large, proprietary computer  systems and  market acceptance of  UNIX" and  other
open operating environments.

    The  license  revenue  growth  in  1994  reflects  continued  strong  demand
particularly for Informix's new generation of database servers and  connectivity
products.  In  1994, Informix  released  INFORMIX-OnLine Dynamic  Server  7.1 on
eleven   symmetric   multiprocessing   platforms.   Informix   also   introduced
INFORMIX-NewEra-TM-  in  1994,  a  second-generation  client/server  application
development tool, and anticipates tools revenue to increase in absolute  dollars
in  1995. However,  there is  significant competition  in the  tools market from
other companies  and their  product offerings:  graphical, character-based,  and
object-oriented.  Many of  these tools  products are  "open," meaning  they will
access data stored on virtually any relational database, including Informix.

    Over half  of Informix's  net revenues  are derived  from its  international
operations  (see  Note  7 of  Notes  to Consolidated  Financial  Statements). In
Europe, most revenues and expenses are denominated in local currencies. In  1994
and  1992, the U.S. dollar weakened against the major European currencies, which
resulted in  higher revenue  and  expenses recorded  when translated  into  U.S.
dollars  and  compared with  the corresponding  prior years.  In 1993,  the U.S.
dollar strengthened significantly against  the major European currencies,  which
resulted  in  lower  revenue and  expenses  recorded when  translated  into U.S.
dollars and  compared with  the prior  year. Through  1994, most  revenues  from
Asia/Pacific,  Canada, and Latin  America were denominated  in U.S. dollars. The
translations  of  the  revenues  for  these  regions  were  less  influenced  by
fluctuations  in foreign  exchange rates.  Informix incurred  approximately $0.4
million in foreign exchange loss in Mexico in the fourth quarter of 1994 due  to
the instability of the economic climate in this country. In the future, Informix
expects  these currency  fluctuations in Mexico  and, to a  lesser extent, other
Latin America countries to continue.

    Approximately 55  percent, 58  percent,  and 53  percent of  Informix's  net
revenues  were derived from sales to foreign customers for 1994, 1993, and 1992,
respectively. The increase in foreign revenues in absolute dollars is  primarily
attributable  to  the establishment  of new  subsidiaries  and sales  offices in
Europe, Asia/Pacific, and Latin America, and continued international  acceptance
for Informix's new and existing technology. Excluding the RCAS contract, foreign
revenue represented 58 percent of net revenues in 1992.

    Informix's  distribution markets were reorganized into three general markets
at the beginning of  the second quarter of  1994: North America, Europe,  Middle
East,  and Africa; and the Intercontinental  Group, consisting of Latin America,
Japan, and the Asia/Pacific region. These organizations contributed 46  percent,
38  percent, and 16  percent of Informix's net  revenues, respectively, in 1994,
compared to 43 percent, 41 percent and 16 percent, respectively, in 1993, and 43
percent, 42 percent  and 15 percent,  respectively in 1992  (excluding the  RCAS
revenue in North America).

</TABLE>

    Excluding amortization of previously capitalized software development costs,
costs  of software distribution as a percentage of license revenue declined to 5
percent in  1994  and in  1993  from  7 percent  in  1992. The  decreases  as  a
percentage  of license revenue are the result  of the recording of several large
contracts which have low associated  costs of software distribution since  these
customers  generally  manufacture  the  software  themselves,  as  well  as cost
reduction programs implemented by Informix in 1992 and 1993.

    The increase in amortization of  capitalized software in 1994 resulted  from
the  release of  several products in  the second  half of 1994.  The decrease of
amortization of capitalized  software in  absolute dollars  in 1993  was due  to
several projects being fully amortized in early 1992.

    The decreases in cost of services as a percentage of service revenue in both
1994 and 1993, compared to their corresponding prior year periods, are primarily
due to higher growth in maintenance revenues, derived from product update rights
and  technical  support,  than  in maintenance  expenses,  primarily  related to
technical customer support.

    The increase in sales and marketing  expenses, in absolute dollars and as  a
percentage  of net  revenues, in 1994  and 1993 compared  to their corresponding
prior year  periods, was  a result  of increased  sales personnel  worldwide  as
Informix  expanded its investment  in the worldwide  direct sales organizations,
opening of new subsidiaries, acquisition of several foreign distributors, higher
commission expense  associated  with the  increase  in revenues,  and  increased
marketing  programs associated with new product launches. Excluding RCAS revenue
and associated expenses in 1992, sales and marketing expenses were 37 percent of
net revenues.

    RESEARCH AND DEVELOPMENT EXPENSES

    In accordance  with FAS  86, Informix's  research and  development  expenses
exclude  capitalized software  costs of $13.6  million in 1994,  $8.6 million in
1993, and $5.0  million in 1992,  and exclude amortization  costs of  previously
capitalized software (see Note 1 of Notes to Consolidated Financial Statements).
The  following table  summarizes research  and development  costs for  the prior

- ------------------------
* Excludes RCAS license revenue in 1992.

    The increase in  research and development  expenditures in absolute  dollars
and  as  a  percentage of  net  revenues from  year  to year  was  attributed to
increased  personnel  and  consultants  working  on  new  products  and  product
extensions.

    The proportion of capitalized expenditures as a percentage of total incurred
expenses  increased from year  to year as several  major projects in development
had reached technological feasibility. Informix  expects the proportion of  work
on  capitalized  projects in  1995 as  a  percentage of  net revenues  to remain
relatively  stable  compared  to  1994   as  other  major  new  products   reach
technological  feasibility in 1995,  and capitalization of  the related software
development costs begins.

</TABLE>

    General and administrative  expenses in 1994  remained relatively flat  with
1993  and 1992  in absolute  dollars. Excluding  the RCAS  contract, general and
administrative expenses were  12 percent  of net  revenues in  1992. The  slight
increase  in absolute dollars from year to year was primarily due to an increase
in  the  costs  of  supporting   Informix's  international  operations  as   new
subsidiaries  and branch offices were established and existing subsidiaries were
expanded.

    LITIGATION SETTLEMENT

    In 1992, a  charge of  $10.5 million  was taken  for the  settlement of  the
securities  class  action  lawsuit filed  against  Informix and  certain  of its
officers and directors in 1988. The settlement, which was completed in May 1993,
does not  constitute an  admission of  liability or  wrongdoing on  the part  of

                                       62
<PAGE>
Informix  or on the part of any of its current or former officers and directors.
The settlement represents  a decision by  Informix's Board of  Directors that  a
settlement   at  the  time  was  in  the  best  interest  of  Informix  and  its
stockholders.

    Interest income in 1994 remained flat compared with 1993 despite higher cash
and investments  as  Informix  invested  a large  percentage  of  its  cash  and
investments in tax-exempt securities. The increase in absolute dollars from 1992
to  1993  resulted  from  higher  balances  of  cash  and  cash  equivalents and
short-term investments.

    Interest expense in 1994 and  1993 consists principally of interest  expense
on  capital leases of certain computer and office equipment. Interest expense in
1992 consists  primarily  of  interest expense  on  convertible  debentures  and
capital  leases of certain computer and office equipment. The decrease from 1992
to 1993  resulted primarily  from the  call for  redemption of  the  convertible
debentures in the fourth quarter of 1992.

    OTHER EXPENSE, NET

    Informix  recognized net  other expense of  $2.6 million,  $1.3 million, and
$1.4 million in 1994,  1993 and 1992, respectively.  In 1994, net other  expense
primarily  consisted of  foreign exchange losses,  net, and  expenses related to
Informix's financing  programs  for  accounts receivable.  In  1993,  net  other
expense primarily consisted of foreign exchange losses, net, partially offset by
a  reversal  of a  liability which  was  determined to  be no  longer necessary,
related to a real  estate partnership. In 1992,  net other expense consisted  of
foreign  exchange  losses, net,  partially  offset by  a gain  on  a sale  of an
investment.

</TABLE>

    Informix's effective tax rate increased to 36.0 percent of pretax income  in
1994  and  1993 from  22.6  percent in  1992.  This increase  resulted  from net
operating loss and tax  credit carryovers which  were substantially utilized  in
1992  and  the 1.0  percent  increase in  the U.S.  federal  income tax  rate in
1993. Informix's effective tax rate for fiscal years 1994 and 1993 is less  than
the  combined  federal and  state statutory  rate primarily  due to  the federal
research and development  credit and  the permanent reinvestment  offshore of  a
portion  of the earnings of Informix's  lower-taxed Irish operations. The amount
considered permanently invested in  the Irish operations may  very from year  to
year and may affect Informix's effective tax rate.

</TABLE>

    Cash   generated  by  operations  provided   sufficient  resources  to  fund
Informix's headcount growth and  capital asset needs  in all periods  presented.
The  increase in  net cash  and cash equivalents  provided by  operations in the
first nine months of 1995  compared with the same  period in 1994 was  primarily
attributable to higher income before depreciation and amortization charges.

    The  increase in  cash and cash  equivalents provided by  operations in 1994
compared with  1993 was  due mainly  to higher  income before  depreciation  and
amortization  charges, increased accounts payable  and accrued expenses, and the
litigation settlement  payment  in 1993,  partially  offset by  an  increase  in
accounts receivable.

    Accounts  receivable increased by $23.2 million in 1994 and by $45.4 million
in 1993, principally  as a  result of  increased sales.  Days sales  outstanding
decreased to 79 days in the fourth quarter of 1994 from approximately 97 days in
the fourth quarter of 1993.

    Net  accounts receivable increased by $40.3 million in the first nine months
of 1995 as compared to  the fourth quarter of 1994,  principally as a result  of
higher  sales partially offset by strong collections  and the use of third party
financing programs. Days sales  outstanding was 86 at  October 1, 1995  compared
with  79  at December  31, 1994.  Commencing in  late 1993,  Informix instituted
programs to  have  third-party  financial  institutions  provide  financing  for
extended credit terms instead of such terms being provided by Informix. The days
sales  outstanding  ratio is  dependent on  many factors,  including the  mix of
contract-based revenue with significant OEMs and large corporate and  government
end-users  versus  revenue recognized  on shipments  to application  vendors and
distributors and the success of Informix's financing programs. Although a  large
portion  of Informix's revenues are  derived from resellers, Informix's revenues
since 1993, particularly in Europe, have shifted substantially from distributors
to direct end-users.  These end-user  sales contracts  frequently bear  extended
payment  terms  which result  in an  increase in  days sales  outstanding ratios
unless the  contracts  are financed.  The  aforementioned shift  in  distributor
channels is likely to continue as products and markets mature. Informix is using
a  variety of  activities to  reduce the  days sales  outstanding ratio.  In the
future, Informix expects this ratio to vary within the range which prevailed  in
the last nine months; however, there is no assurance that it will do so.

    Excluding  investments of excess cash, net cash and cash equivalents used in
investing activities increased in  1994 compared to 1993  and also increased  in
the  first  nine months  of 1995  in the  first  nine months  of 1995  and 1994,
respectively. During the years ended  Informix acquired $36.0 million and  $19.7
million,  respectively, of  capital equipment  consisting primarily  of computer
equipment, computer software and office equipment and in 1994 and 1993, Informix
acquired $25.2 million and $22.1 million, respectively of capital equipment. The
increase of  capital  equipment purchases  in  the  first nine  months  of  1995
resulted   from  Informix's  growing  employee  headcount,  the  replacement  of

                                       64
<PAGE>
obsolete equipment and  investment in  new technology. In  the future,  Informix
anticipates  the actual level of capital spending will be dependent on a variety
of factors,  including Informix's  business  requirements and  general  economic
conditions.

    In  January 1995,  Informix acquired a  90 percent interest  in the database
division of ASCII Corporation, a distributor of its products in Japan.  Informix
will  acquired  the  remaining 10  percent  interest in  January  1996. Informix
accounted for  the acquisition  as a  purchase. The  purchase price  of  ASCII's
database  division was approximately  $46.0 million, of  which $34.8 million has
been allocated to intangible assets acquired.

    In April 1995,  Informix acquired  an 80  percent interest  in the  database
division  of Daou Corporation, a distributor  of its products in Korea. Informix
will acquire  the remaining  20 percent  by January  1997. The  acquisition  was
recorded  as a purchase.  The purchase price of  this business was approximately
$4.3 million,  of  which  approximately  $4.0  million  has  been  allocated  to
intangible assets acquired.

    In  October  1995, Informix  acquired Stanford  Technology Group  ("STG"), a
U.S.-based company that  provides on-line analytical  processing technology,  in
exchange  for approximately 570,000 shares of  its common stock. The transaction
will be accounted for as a pooling of interests.

    Net cash and cash equivalents provided  by or used in, financing  activities
in  1994 and  1993 included  payments on  capital leases  and the  repurchase of
Informix's common stock offset  by proceeds from the  sale of Informix's  common
stock to employees.

    Net  cash and cash equivalents provided by financing activities in the first
nine months of 1995 consisted primarily of proceeds from the sale of  Informix's
common  stock to employees, partially offset  by payments on capital leases. Net
cash and cash equivalents used in financing activities in the first nine  months
of  1994 included repurchases of Informix's common stock and payments on capital
leases, partially offset by proceeds from the sale of Informix's common stock to
employees.

    In June 1995, the Board of Directors authorized a two-for-one stock split of
Informix's common  stock, effected  in the  form of  a stock  dividend.  Through
December  31, 1994, Informix had repurchased  3,580,000 shares with an aggregate
cost of approximately $32.1 million on  the open market under a plan  authorized
by the Board of Directors in 1994. No repurchases have been made in 1995.

   
    Informix  expects  that  current  balances  of  cash,  cash  equivalents and
short-term  investments  will  be  sufficient  to  fund  anticipated  levels  of
operations   at  least  through  1996  and  may  be  used  for  investments  and
acquisitions to  supplement  internal revenue  growth  and for  other  corporate
purposes.

(1) Options granted in 1995 are exercisable  starting 12 months after the  grant
    date,  with 25% of the shares becoming  exercisable at that time and with an
    additional 25% of the option shares becoming exercisable on each  successive
    anniversary  date,  with full  vesting occurring  on the  fourth anniversary
    date. Under the terms of the option plan, the Compensation Committee retains
    discretion, subject  to plan  limits,  to modify  the terms  of  outstanding
    options.  The  options were  granted for  a  term of  ten years,  subject to
    earlier termination in certain events related to termination of  employment.
    The  number  of  shares  shown  has been  adjusted  to  give  effect  to the
    two-for-one stock split  effected in the  form of a  stock dividend in  June
    1995.

(2) The  exercise price and tax withholding  obligations related to exercise may
    be paid by delivery of already owned shares, subject to certain conditions.

(3) The 5% and the 10% assumed rates  of appreciation are mandated by the  rules
    of  the Securities and  Exchange Commission and  do not represent Informix's
    estimate or projection  of the  future Common  Stock price.  Of course,  the
    actual realizable value of the stock options will depend on the appreciation
    of  the stock  price and the  executive officer's  continued employment with
    Informix through the applicable vesting periods of the stock options.

(4) The terms of the stock options granted  to Messrs. White and Graham in  1995
    and  prior years provide  that such stock options  shall become fully vested
    and immediately exercisable in the event of a change in control of Informix.
    A change  in  control of  Informix  is defined  as  a sale  or  exchange  of
    securities by the stockholders of Informix, a merger involving Informix or a
    sale  of all  or substantially  all of the  assets of  Informix, wherein the
    stockholders of Informix immediately before the sale or exchange, merger  or
    sale of assets do not retain, directly or indirectly, at least a majority of
    the  beneficial interests in  the voting securities of  (i) Informix, in the
    event of a sale or exchange, (ii) the resultant corporation, in the event of
    a merger, or (iii) the transferee corporation or corporations, in the  event
    of a sale of assets.

COMPENSATION OF DIRECTORS

   
    For the  fiscal year  ended December  31, 1995,  Informix paid  all  outside
directors  as follows:  $1,000 for  each Board  meeting attended;  $500 for each
meeting of  the  Audit and  Compensation  Committees attended;  and  $2,000  per
quarter.  For the  fiscal year ending  December 31, 1996,  the outside directors
will continue  to  receive the  same  compensation  as they  received  in  1995.
Informix  reimburses  directors for  travel  expenses associated  with attending
board meetings. From time to time, Informix may invite the directors' spouses to
accompany the directors to a board meeting. When invited, Informix also pays the
travel expenses incurred by the spouses. In 1995, these spousal travel  expenses
were  less than $5,000 per director.  In addition, the outside directors receive
options to acquire  shares of Informix's  Common Stock under  the Informix  1989
Outside  Directors Stock  Option Plan (see  the "Outside  Directors Stock Option
Plan"). Employee directors did not  in 1995, and will  not in 1996, receive  any
additional compensation for serving as a director.
    

OUTSIDE DIRECTORS STOCK OPTION PLAN

   
    At  the 1990 Annual  Meeting of Stockholders,  the stockholders approved the
adoption  of  the  Informix  1989  Outside  Directors  Stock  Option  Plan  (the
"Directors  Option Plan"). Only  directors who are not  employees of Informix or
any Informix or subsidiary corporations of  Informix are eligible to be  granted
options   under  the  Directors  Option  Plan.  The  Directors  Option  Plan  is
administered by a  committee appointed by  the Board of  Directors of  Informix,
which currently is all of the members of the Board. Options for 15,000 shares of
stock  are granted  automatically upon election  or re-election to  the Board of
Directors.
    

   
    Options granted under  the Directors  Option Plan are  evidenced by  written
agreements  specifying the  number of  shares of  stock covered  thereby and the
option price, which price shall be the fair market value of the shares as of the
date of grant of the option. No option may be exercised after the expiration  of
ten  years from the date the option is  granted. All options must be granted, if
at all, no later than May 2009. A  total of 1,600,000 shares of Common Stock  of
Informix  (subject to adjustment in the event  of certain changes in the capital
structure of Informix) may be issued under the Directors Option Plan.
    

   
    In 1995, Messrs. Koch and McDonnell  were each granted an option for  30,000
shares  upon re-election  to the  Board which vests  pro-rata over  a three year
period from the date of grant. The number of shares included in such grants  has
been adjusted to give effect to the two-for-one stock split effected in the form
of  a stock dividend in June 1995.  Options issued to terminated directors lapse
30 days after termination as a director and unexercised shares subject to  those
options  are returned to the share reserve and become available for future stock
option grants.
    

                                       71
<PAGE>
    Options  may be exercised by  payment of the option  price in cash, check or
cash equivalent. All options  granted under the Directors  Option Plan shall  be
nonqualified  stock options, that is options  which do not meet the requirements
of Section 422 of  the Internal Revenue  Code of 1986,  as amended. Options  are
non-assignable  and non-transferable and may be  exercised only by the optionee.
In the  event of  a transfer  of control  or the  dissolution of  Informix,  the
optionee  shall have 30 days within which  to exercise the options to the extent
of all or any part of the shares subject to such options.

    The Board may terminate or amend the Directors Option Plan at any time,  but
without  the approval  of stockholders,  the Board  may not  amend the Directors
Option Plan to increase the  number of shares subject  thereto or to change  the
class of persons eligible to receive options thereunder.

   
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
    

   
    The following individuals served as members of the Compensation Committee of
the  Informix Board of Directors: Albert F. Knorp, Jr., James L. Koch, Thomas A.
McDonnell and Cyril J. Yansouni. Mr. Knorp also served as an Assistant Secretary
of Informix during  the fiscal  year ended December  31, 1995  and continues  to
serve  in such capacity.  Mr. Knorp is of  counsel to the law  firm of Gray Cary
Ware &  Freidenrich,  which provided  legal  services  to Informix  in  1995  in
connection  with corporate  and licensing  matters. Thomas  A. McDonnell  is the
President, Chief Executive Officer and a director of DST Systems, Inc.  ("DST").
Affiliates  of DST paid approximately $500,000  to Informix in 1995 for products

CERTAIN TRANSACTIONS

   
    In June 1993, Informix made  a loan in the  principal amount of $150,000  to
Mr.  Saranga,  Senior Vice  President,  Product Management  and  Development, in
connection with his accepting employment by  Informix. The loan is secured by  a
second  deed of trust on property acquired  by Mr. Saranga in California and was
originally due and payable in full on the earliest of June 2, 1995, the date Mr.
Saranga sold his Connecticut property or the date Mr. Saranga's employment  with
Informix was terminated. In June 1995, Mr. Saranga and Informix amended the loan
to  increase the  interest rate  of 3.56% per  annum to  6.55% per  annum and to
provide that $30,000  of principal, and  accrued interest, will  be forgiven  on
June  2, 1996  and each anniversary  thereafter provided Mr.  Saranga remains an
employee of Informix.  The loan  continues to provide  that the  full amount  of
unpaid principal and accrued interest will become immediately due and payable on
the date Mr. Saranga's employment with Informix is terminated for any reason.
    

    Mr.  Knorp, a director  of Informix, is of  counsel to the  law firm of Gray
Cary Ware & Freidenrich,  which provided legal services  to Informix in 1995  in
connection with corporate and licensing matters.

   
    Thomas  A.  McDonnell,  a  director of  Informix,  is  the  President, Chief
Executive Officer and a  director of DST. Affiliates  of DST paid  approximately
$500,000 to Informix in 1995 for products and services.

                               ILLUSTRA BUSINESS

BACKGROUND

    Illustra develops, produces, markets and supports object-relational database
systems  and  software  tools.  It   also  provides  consulting,  training   and
maintenance  services. Illustra develops  its systems software  and tools at its
development center  in  Oakland,  California.  Its  products  are  sold  through
multiple channels of distribution.

    Illustra  was incorporated in Delaware in July 1992. Its headquarters are in
Oakland, California. Certain of its marketing and sales activities in Europe are
conducted through wholly-owned subsidiaries in the United Kingdom and France.

PRODUCTS

    Illustra markets a proprietary object-relational database management  system
("ORDBMS")  and tools for applications  in multimedia and entertainment, digital
media publishing and  financial services. Illustra  believes the development  of
its  ORDBMS represents one of the most significant technological advances in the
25-year history  of  relational  and object-oriented  database  management.  The
Illustra-TM- Server allows users to store, manage and analyze complex multimedia
data  such as images, audio, video  and Hypertext Markup Language ("HTML") files
in a single database with  traditional text and numbers using  industry-standard
SQL.

    ILLUSTRA SERVER

   
    The  Illustra Server is a  full-featured database management system designed
for the management of complex  multimedia data, not just numerical  information.
Combining  the  capabilities  of  object-orientation  with  those  of relational
databases,  Illustra  provides  support  for  industry-standard  SQL  with  SQL3
extensions, thereby enabling existing relational database developers to leverage
their  existing development expertise. The Illustra Server delivers flexible and
controllable security and is designed for  rapid access to terabytes of  complex
data by tens to hundreds of simultaneous users. The first production release was
shipped  in August 1993, and  the most recent release  -- Illustra Server 3.2 --
first shipped in October 1995.
    

    ILLUSTRA DATABLADE-REGISTERED TRADEMARK- MODULES

    Illustra develops and markets  "snap-in" software modules, called  DataBlade
modules,  which  extend the  database's  ability to  handle  new data  types and
provide new "methods" for  specific handing of the  data. DataBlade modules  can
work  alone  or in  conjunction  with one  another.  DataBlade modules  can even
include completely new access methods, providing  quick access to data not  well
served by the B-trees of the RDBMS vendors. Illustra DataBlades are developed by
Illustra or by third party vendors. Current Illustra DataBlade modules include:

    - IMAGE  DATABLADE.   The Illustra Image  DataBlade module  supports over 50
      image formats (E.G. GIF, TIFF, PICT), both color and monochrome.  Examples
      of  image manipulation include rotation, edge enhancement and convolution.
      With the Image DataBlade, expertise at managing images is in the  database
      manager, instead of in each application.

    - 2D SPATIAL DATABLADE.  The Illustra 2D Spatial DataBlade module supplies a
      set   of  over  200  functions  to  allow  manipulation  and  querying  of
      two-dimensional spatial data, including points, lines, polygons and  other
      spatial and location data.

    - 3D SPATIAL DATABLADE.  The Illustra 3D Spatial DataBlade module supplies a
      set  of over 1,000 functions to allow manipulation and querying of spatial
      data  that  enables  the  database  to  manage  three-dimensional  spatial
      information.

    - TEXT  DATABLADE.  The Illustra Text  DataBlade module supplies a large set
      of functions to allow  easy development of  complex searches --  accessing
      documents by their content. Stored text can be queried for keyword matches
      as well as for idea and concept relevance.

                                       75
<PAGE>
    - TIMESERIES  DATABLADE.   The Illustra TimeSeries  DataBlade module enables
      the  database  to  manage  time  series  and  temporal  data,  which   are
      particularly  useful for systems used in the financial services arena. The
      DataBlade supports a regularly repeating  time-stamped series of any  type
      or  assortment of  data--integer, floating  point numbers,  currency, text
      fields, spatial information that  can be represented  in digital form,  or
      any  structure or combination of these.  The granularity of time recording
      can be in a variety of units. Support for two new data types, time  series
      and calendars, and over 40 functions to manage them, is included.

    - S-PLUS   DATABLADE.     The   Illustra  S-Plus   DataBlade  module   is  a
      user-installable extension to  the Illustra Server  that adds support  for
      over  1,000 statistical functions. The S-Plus DataBlade module maps S-Plus
      data types  to Illustra  data  types, making  it possible  to  incorporate
      S-Plus functions directly inside of Illustra SQL.

    - WEB DATABLADE.  The Illustra Web DataBlade module is an innovative product
      which  substantially  reduces  the  required  effort  (and  thus  cost) of
      developing World Wide Web ("WWW")-enabling database applications. The  Web
      DataBlade consists of a core functionality that makes it possible to store
      HTML  pages in the database. These pages can contain SQL queries which are
      triggered when accessed and the results are formatted. The programmer  can
      therefore   generate  HTML   pages  automatically   without  knowledge  of
      programming languages such as C,  perl or tcl and  focus on the "look  and
      feel" of the pages, using only industry standard HTML and SQL.

    - VIR  DATABLADE  AND VIR  IMAGE VIEWER.    The Illustra  Visual Information
      Retrieval ("VIR") DataBlade is a content-based image retrieval system  for
      retrieving  images, animation and video from complex multimedia databases.
      Users can perform searches on any kind of image, including video, based on
      the actual content  of the  image. Illustra  also sells  the Illustra  VIR
      Image  Viewer, a graphical user interface to the VIR DataBlade module that
      allows users to visually  search through collections  of images stored  in
      the Illustra Server.

    ILLUSTRA TOOLS AND TOOLKITS

    Illustra's  tool  and  toolkit  products  provide  mechanisms  for  enabling
application development against the Illustra Server. This suite of tools changes
application development from low-level programming to high-level "componentware"
designed to serve  developers creating  multimedia or WWW  applications for  the
Illustra Server. Illustra's tools and toolkits include:

    - ODBC  DRIVER.    A  high  performance  driver  enabling  rapid application
      development by providing  an industry-standard database  interface to  the
      Illustra  Server and  DataBlade modules  from industry  standard Microsoft
      products. Illustra's ODBC  driver allows Windows  desktop applications  to
      interact with Illustra's object relational database technology.

    - SCHEMA  KNOWLEDGE.  A tool for developers working with schema objects such
      as tables,  functions, data  types, casts,  operators and  aggregates.  It
      provides an easy-to-use graphical interface so the developer can "see" the
      schema  information  in  the database,  allowing  easy  navigation through
      complex designs.

    - ILLUSTRA C++  INTERFACE.   By transforming  the underlying  mechanism  for
      communicating  with  the  servers  into  a  high-level  collection  of C++
      classes, this Microsoft-compatible tool drastically reduces code and makes
      it easy to create, debug and modify applications for the Illustra Server.

    - ILLUSTRA CLIENT  TOOLKIT  FOR  WINDOWS.   Illustra  tools  native  to  the
      Microsoft  Windows NT operating system  for rapid application development.
      Tools include Illustra Query, enabling development and debugging using  AD
      HOC  SQL queries  rather than application  programming interface language,
      and the  Visual Basic  interface for  accessing the  Illustra Server  from
      Visual Basic rather than prototype C/C++.

<PAGE>
    OTHER PRODUCTS AND SERVICES

    In  addition  to those  described  above, Illustra's  products  and services
include the following:

    - OBJECT KNOWLEDGE.  Illustra's Object Knowledge is a system of programs and
      libraries that enable applications to graphically depict data in  Illustra
      databases  so  that users  can  literally visualize  database information.
      Graphically displayed data is much more readily understood and therefore a
      more useful form of information than the traditional spreadsheet format of
      tabular numerical data.

    - DATABLADE  DEVELOPER'S  KIT.    The  DataBlade  Developer's  Kit  includes
      machine-readable  source code,  the Illustra  Architecture Manual  and the
      Example  DataBlades  Manual  to  allow  developers  to  develop  DataBlade
      modules.

    - GATEWAYS.    Illustra  offers a  Sybase  Gateway that  enables  access and
      updates through the Illustra  Server to data  stored in Sybase  databases.
      Data  from the  Sybase server  can be  fetched, qualified,  aggregated and
      combined with Illustra data as if it were from the same source.

    - CONSULTING  SERVICES.    Illustra  offers  consulting  services  to   help
      customers  with  a  variety  of  design,  development  and  implementation
      activities. Illustra also  has a variety  of approved systems  integration
      partners who have additional resources.

    - TRAINING.   Illustra offers a variety of courses to assist in learning the
      Illustra product set.  Classes incorporate  lectures, demonstrations  and,
      often, lab sessions.

MARKETING AND DISTRIBUTION

    Illustra   markets   its  software   through   its  direct   end-user  sales
organization, as  well as  its indirect  OEM, value-added  reseller ("VAR")  and
value-added distributor ("VAD") network.

    There  are four  territory operational  groups. The  North America territory
group is responsible  for marketing  and supporting Illustra  products in  North
America  through its end-user sales organization, OEMs, VARs and VADs. The Japan
territory group, in conjunction with its master distributor, is responsible  for
localizing,  translating, marketing  and supporting  Illustra products  in Japan
through its  end-user sales  organization,  OEMs, VARs  and VADs.  The  European
territory  group  (with  wholly-owned  subsidiaries in  the  United  Kingdom and
France) is  responsible  for  translating,  marketing  and  supporting  Illustra
products  in Europe through its end-user sales organization, OEM, VARs and VADs.
The Intercontinental  territory  group (which  covers  all areas  not  mentioned

sales organization, OEMs, VARs and VADs.

    OEMS AND MASTER DISTRIBUTORS

    Illustra products  are  marketed  to  OEMs  and  master  distributors  under
agreements  which grant OEMs and master distributors the right to make copies of
the product  and distribute  the copies  with  the OEM's  hardware or  to  other
authorized resellers.

    VARS, VADS AND AUTHORIZED RESELLERS

    Illustra  markets  its products  to  large corporate  customers  through its
end-user sales  organization  and  independent VADs  and  authorized  resellers.
Illustra  employs  a  staff of  field  sales representatives  and  field support
personnel who  solicit  orders  primarily from  end-users  and  provide  product
training  and sales support to VARs, VADs, other authorized resellers and larger
corporate customers.

CUSTOMERS

    As of December 31, 1995, Illustra had licensed its products to approximately
240 end-user customers, some  of which had licensed  multiple copies of  various
products,  and Illustra's VARs, VADs and other authorized resellers had licensed
Illustra's products  to  additional  end-users and  resellers.  Illustra  offers
technical  support  for  all  of  its  products  through  its  technical support
department

                                       77

located in the  corporate headquarters. Revenues  received from Fujitsu  Network
Transmission  Systems, Inc.  represented approximately  13% of  Illustra's total
revenues for fiscal  year 1995, and  revenues from Digital  Equipment Corp.  and
Wyse  Technology Inc.  represented approximately  29% and  22%, respectively, of
Illustra's total revenues for fiscal year 1994.

    Certain payments received  from customers  have been  recorded initially  as
deferred  revenue  and  are recognized  as  revenue in  subsequent  periods. See
"Illustra Management's  Discussion  and  Analysis  of  Financial  Condition  and
Results of Operations" and Note 11 of Notes to Consolidated Financial Statements
of Illustra.

PRODUCT DEVELOPMENT

    The  database software market  is fiercely competitive  and characterized by
rapid  technological  change,  which  requires  industry  participants  to  make
continuous  expenditures of  substantial resources  for product  enhancement and
innovation. Illustra  is committed  to  the creation  of  new products  and  the
enhancement  of  existing  products.  It  maintains  its  development  center in
Oakland, California which is responsible for product development,  documentation
and  quality  assurance. The  development center  works  closely with  sales and
marketing personnel in the marketing of  its products and the definition of  new
or enhanced product features.

    During  fiscal years 1995, 1994 and  1993, Illustra spent approximately $4.8
million, $2.9  million  and  $884,000, respectively,  on  product  research  and
development.   These  amounts  represent  approximately  327%,  353%  and  442%,
respectively, of revenues  in each  of those periods.  All software  development
costs have been expensed as incurred.

    In  addition,  certain of  Illustra's existing  DataBlade modules  have been
developed by  third-party developers  and are  sold on  a stand-alone  basis  or
incorporated  into  products developed  by  Illustra. Illustra  anticipates that
additional DataBlade modules  will be  developed by  third parties  and sold  by
Illustra  in  the  future.  Illustra typically  pays  third-party  developers of
DataBlade modules royalties based on the number of licensed copies sold.

COMPETITION

    Database development has been ongoing in the industry as the need to  store,
manage  and  analyze  more  rich and  complex  data  has  increased. Traditional
relational database vendors have realized this  need and are developing ways  to
add  to their RDBMS products technology to  handle multimedia data types such as
those handled effectively  by Illustra's products.  Illustra sees its  principal
competitors  to be companies such as  Oracle Corporation, Sybase Inc., Informix,
IBM Corporation, CA Ingres (a  subsidiary of Computer Associates) and  Microsoft
Corporation,  all of  which have  substantially greater  financial and personnel
resources than Illustra.

    Illustra believes the principal competitive factors in its industry  include
database  performance (I.E., the  speed with which  operations can be executed),
database extensibility to handle  new and complex  data types (E.G.,  multimedia
data  such as images, audio and video), database scalability to run on expanding
and  often  heterogeneous  computer  systems,  including  systems  incorporating
various  types of high-performance  parallel processors, and  the ease and speed
with which applications  can be  developed, including the  quality of  available
applications   development  tools.  Illustra   believes  it  currently  compares
favorably with its principal  competitors with respect to  these factors in  the
market segments on which it has concentrated to date.

PROPRIETARY RIGHTS

    Illustra regards its software as proprietary and attempts to protect it with
copyrights,  trademarks and  internal and external  nondisclosure safeguards, as
well as restrictions on transferability that are incorporated into its  software
license  agreements. As  is common  in the  software industry,  Illustra has not
sought to  rely  on  patents to  protect  its  technology. In  addition  to  its
internally-developed  technology,  Illustra uses  some technology  licensed from
third-party  vendors  under  agreements   that  typically  restrict   Illustra's
permitted uses of the licensed technology.

EMPLOYEES

    As of December 31, 1995, Illustra had 180 employees, 169 domestically and 11
internationally.  Of  the  total, 86  were  engaged in  product  development and
support, 43 in marketing, sales and  field operations, 16 in strategic  business
units,  16 in consulting and 10  in administration, human resources and finance.
None of  Illustra's employees  is represented  by a  labor union.  Illustra  has
experienced no work stoppages and believes its employee relations are excellent.

PROPERTIES

    Illustra's corporate offices are located in approximately 65,000 square feet
of  leased office space in Oakland,  California. This lease for these facilities
expires in June 1997. In addition, Illustra leases small amounts of office space
in numerous locations in  the United States and  in foreign countries.  Illustra
believes  its existing facilities are sufficient  for its current operations and
that, for the foreseeable future, any additional facilities that may be required
will be obtainable on reasonable terms.

    Illustra  derives revenue  from the licensing  of its software  and from the
provision of services consisting of  customer support, training, consulting  and
development  projects. Revenue  under product  license agreements  is recognized
upon delivery. Services revenues primarily  consist of maintenance and  customer
training  and  consulting services  and  development contract  fees. Maintenance
revenue is deferred  and recognized  ratably over  the term  of the  maintenance
agreement,  which  is typically  12 months.  Revenue  for customer  training and
consulting is recognized as the  services are performed. Revenue on  development
contracts is recognized based upon achievement of specified milestones.

   
    Illustra's  activities during  fiscal 1993  were devoted  almost entirely to
product development, and Illustra did not record any license revenues during its
first fiscal year of operations. The  first commercial shipment of the  Illustra
Server product was made in August 1993. License revenues were $426,000 in fiscal
1994  and increased by approximately 135% to  $1.0 million in fiscal 1995 on the
strength  of  initial  commercial  shipments  of  Illustra's  products.  Service
revenues  were $200,000  in fiscal  1993 and  increased by  approximately 98% to
$396,000 in fiscal 1994 and an additional 16% to $458,000, or approximately  31%
of  total revenues, in fiscal 1995.  Commercial shipments of Illustra's products
and demand for Illustra's services continued to grow in the first six months  of
fiscal  1996,  as license  revenues  increased by  approximately  five-fold from
$592,000 for the first six  months of fiscal 1995 to  $3.4 million in the  first
six  months of  fiscal 1996.  Service revenues  increased by  over six-fold from
$153,000  in  the  first  six  months  of  fiscal  1995  to  $1.1  million,   or
approximately 24% of total revenues, in the first six months of fiscal 1996.

    Illustra's  ability to sustain growth depends  in part on the timely release
of successful  new and  updated products,  and the  success of  new and  updated
products from its competitors.

    Software  distribution costs consist primarily  of manufacturing and related
costs such  as  media, documentation,  product  assembly and  freight.  Software
distribution  costs  have increased  from  zero in  fiscal  1993 to  $48,000, or
approximately  11%  of  license  revenues,  in  fiscal  1994  to  $160,000,   or
approximately 16% of license revenues, in fiscal 1995. From the first six months
of  fiscal  1995  to the  first  six months  of  fiscal 1996,  cost  of software
distribution increased  by  approximately  227% from  $70,000  to  $229,000  but
decreased as a percentage of license revenues from 12% to 7%.
    

    COST OF SERVICE

   
    Cost  of service, which consists  primarily of technical support, consulting
and training  expense, has  to-date  exceeded service  revenue as  Illustra  has
incurred significant consulting and technical support expenses in order to build
the  organizational infrastructure to support  anticipated future demand for its
products. Cost of service was $150,000 in fiscal 1993, increased to $436,000  in
fiscal  1994 and increased by approximately 228% to $1.4 million in fiscal 1995.
Cost of service increased by approximately  219% from $507,000 in the first  six
months of fiscal 1995 to $1.6 million in the first six months of fiscal 1996 but
decreased as a percentage of service revenues from 331% to 148%.
    

    In  light of Illustra's short three-year  operating history, it is difficult
to formulate any trends or predict any other trends.

    SALES AND MARKETING EXPENSE

   
    Sales and  marketing  expense,  consisting  primarily  of  compensation  and
benefits  of Illustra's sales and marketing  organization, has increased as that
organization and associated infrastructure have grown to include several offices
in the  United  States, Europe  and  two  distributorships in  Asia.  Sales  and
marketing  expense  was $74,000  in fiscal  1993, increased  to $2.3  million in
fiscal 1994 and increased by approximately  78% to $4.0 million in fiscal  1995.
Sales  and marketing expense has to-date exceeded  total revenues as a result of
Illustra's investment in its sales and marketing organization and infrastructure
in support of initial  product sales and anticipation  of future demand for  its
products.  From the first six  months of fiscal 1995 to  the first six months of
fiscal 1996, sales and  marketing expense increased  by approximately 195%  from
$1.7  million to $4.9  million but decreased  as a percentage  of total revenues
from 224% to 109%.
    

    Throughout the remainder of  fiscal 1996, Illustra  will continue to  invest
more  in customer  services, marketing  and research  and development,  and make
personnel additions to its sales force worldwide. These additional expenses  may
adversely affect Illustra's operating performance in fiscal 1996 if there are no
offsetting increases in revenues or reductions in other operating expenses.

    RESEARCH AND DEVELOPMENT EXPENSE

   
    Research and development expense, consisting principally of compensation and
benefits of Illustra's product development organization, has grown substantially
since  inception as  the size and  complexity of  Illustra's product development
activities have increased. All research and development costs to-date have  been
expensed   as   incurred.  Research   and   development  expense   increased  by
approximately 229% from $884,000 in fiscal  1993 to $2.9 million in fiscal  1994
and  increased  again  by approximately  64%  to  $4.8 million  in  fiscal 1995.
Research and  development  expense  increased by  approximately  77%  from  $2.1
million  in the first six months of fiscal 1995 to $3.7 million in the first six
months of fiscal 1996.
    

    GENERAL AND ADMINISTRATIVE EXPENSE

   
    General and administrative expense consists principally of compensation  and
benefits of employees engaged in administration, human resources and finance, as
well  as  occupancy  expense  and  outside  professional  services.  General and
administrative expense increased  by approximately 16%  from $556,000 in  fiscal
1993 to $645,000 in fiscal 1994 and increased again by approximately 71% to $1.1
million  in  fiscal  1995.  General  and  administrative  expense  increased  by
approximately 239%
    

                                       81
<PAGE>
   
from $436,000 in  the first six  months of fiscal  1995 to $1.5  million in  the
first  six months of fiscal 1996. These increases resulted primarily from growth
in Illustra's  administrative  infrastructure  necessary  to  support  expanding
operations and legal and accounting expenses related to the Merger.
    

    INTEREST INCOME

   
    Interest income represents interest earned on cash balances. Interest income
increased by approximately 187% from $24,000 in fiscal 1993 to $69,000 in fiscal
1994 because of higher cash balances. Interest income increased 170% to $186,000
in  fiscal  1995 as  a result  of significantly  increased interest  income from
higher cash  balances.  Interest  income increased  by  approximately  36%  from
$77,000  in the  first six months  of fiscal 1995  to $105,000 in  the first six
months of fiscal  1996 because  an increase  in interest  income resulting  from
higher cash balances and higher interest rates.
    

    INTEREST EXPENSE

   
    Interest  expense results from equipment  leases. Interest expense increased
from $56,000 in 1994 to $67,000 in 1995 and from $30,000 in the first six months
of 1995 to $82,000  in the first  six months of 1996  due to additional  leases.
Additional  financing  was  required for  the  new equipment  purchased  for the
additional employees hired by the Company.

    Since its  inception  in  1993, Illustra  funded  its  operations  primarily
through  private  issuance  of  capital  stock  and  borrowings  under financing
arrangements ($21.7 million and $3.8 million, respectively, through December 31,
1995). Cash used in  operating activities was  approximately $1.2 million,  $4.7
million,  $5.7 million and  $6.6 million in  fiscal 1993, 1994  and 1995 and the
first six months of fiscal 1996,  respectively. Illustra used each of  $527,000,
$321,000,  $1.3 million and $2.5  million in fiscal 1993,  1994 and 1995 and the
first six months of fiscal 1996, respectively, for the purchase of equipment  to
be  used by employees. Illustra anticipates that increased investment in capital
equipment will be required in the future to support its anticipated  operations.
As  of  December 31,  1995,  Illustra had  no  material commitments  for capital
expenditures.
    

    Illustra invests excess funds in short-term investments such as money market
funds, short-term commercial paper and repurchase agreements.

   
    As of December 31, 1995, Illustra had cash, cash equivalents and investments
of $1.0 million and a working capital deficit of $5.3 million. Although Illustra
does not have  a bank line  of credit, it  has equipment financing  arrangements
with two commercial lenders which were fully drawn down as of December 31, 1995.
In December 1995, Illustra entered into a credit arrangement with Informix under
which  Illustra may borrow up to $5 million for working capital requirements. As
of December 31, 1995, the  Company had borrowed $2.0 million,  in the form of  a
note  payable,  under the  Informix arrangement.  Illustra anticipates  that its
existing cash balances  and financing  sources will  be sufficient  to meet  its
working  capital and  capital expenditure  requirements through  the anticipated
closing date of the Merger; however, if the closing of the Merger is delayed  or
the  Merger does not occur for any  reason, Illustra will have an immediate need
for substantial  additional  financing. There  can  be no  assurance  that  such
financing will be available on reasonable terms, if at all.

(1) All options vest at the rate of 20% at the end of the first year of  service
    with  Illustra and then an additional 1/60  per month until all options have
    become vested at the end of five years' service with Illustra. In the  event
    an  option was granted  to an existing  employee of Illustra  (rather than a
    newly-hired employee), such option vests  at the rate described above  based
    on the grant date of such option.

(2) The potential realizable value is calculated based on the term of the option
    at  its time of grant. It is calculated  by assuming that the stock price on
    the date  of  grant appreciates  at  the indicated  annual  rate  compounded
    annually  for the entire term of the  option and the option is exercised and
    sold on the last day of its term for the appreciated stock price. No gain to
    the optionee is possible  unless the stock price  increases over the  option
    term, which will benefit all stockholders.

                  APPLICABILITY OF CALIFORNIA LAW TO ILLUSTRA

    Section 2115 of the CGCL makes substantial portions of the CGCL  applicable,
with  limited exceptions, to  a foreign corporation  with more than  half of its
outstanding stock held of record by  persons having addresses in California  and
more  than half of its  business conducted in the  state (as measured by factors
based on a corporation's  levels of property, payroll  and sales determined  for
California  franchise tax purposes), irrespective  of the corporation's state of
incorporation. Although Illustra is incorporated  in Delaware, it is subject  to
Section  2115. The statutory provisions of the CGCL to which Illustra is subject
include but are  not limited to  provisions governing a  director's standard  of
care  in performing  the duties  of a  director, a  stockholder's right  to vote
cumulatively in any election of  directors, a director's or stockholder's  right
to inspect corporate records, indemnification requirements concerning directors,
officers  and  others and  the  corporate requirements  to  effectuate corporate
reorganizations (including mergers and acquisitions). Section 2115 also  invokes
the application of Chapter 13 of the CGCL to the Merger with respect to Illustra
stockholders  who elect to exercise dissenters'  rights. Under Section 2115, the
provisions of the  CGCL made applicable  pursuant to such  section apply to  the
exclusion  of the law  of the jurisdiction  in which the  foreign corporation is
incorporated.

    Upon completion  of  the  Merger, the  statutory  protections  available  to
Illustra stockholders pursuant to Section 2115 will cease to exist.

                          COMPARISON OF CAPITAL STOCK

DESCRIPTION OF INFORMIX CAPITAL STOCK

    The  authorized capital stock of Informix  consists of 350,000,000 shares of
Common Stock, $0.01 par  value, and 5,000,000 shares  of Preferred Stock,  $0.01
par value.

    INFORMIX  COMMON STOCK.   As of December 31,  1995, there were approximately
135,327,804 shares  of  Informix Common  Stock  outstanding held  of  record  by
approximately  1,763  stockholders. Informix  Common Stock  is listed  on Nasdaq
under the symbol "IFMX."  Holders of Informix Common  Stock are entitled to  one
vote  per  share  on all  matters  to be  voted  upon by  the  stockholders. The
stockholders do not have a right to take action by written consent nor may  they
cumulate  votes in connection with the  election of Directors. Both the Restated
Certificate of  Incorporation  and the  Bylaws  of Informix  contain  provisions
requiring  the affirmative vote of the  holders of two-thirds of the outstanding
Common Stock of Informix to amend  the cumulative voting or stockholder  written
consent provisions. The holders of Informix Common Stock are entitled to receive
ratably  such dividends,  if any, as  may be declared  from time to  time by the
Board of Directors out of  funds legally available therefor.  In the event of  a
liquidation,  dissolution or  winding up  of Informix,  the holders  of Informix
Common Stock are entitled to share ratably in all assets remaining after payment
of liabilities. The Informix Common Stock has no preemptive or conversion rights
or other subscription rights. There are no redemption or sinking fund provisions
applicable to  the Informix  Common Stock.  All outstanding  shares of  Informix
Common  Stock  are fully  paid and  non-assessable, and  the shares  of Informix
Common Stock to be outstanding upon completion of the Merger will be fully  paid
and non-assessable.

    PREFERRED   STOCK.    Informix  has  5,000,000  shares  of  Preferred  Stock
authorized, of  which  350,000  shares are  designated  Series  A  Participating
Preferred  (the "Series A Preferred"), and no shares are outstanding. The Series
A Preferred has been designated for use in connection with the Preferred  Shares
Rights Agreement. See "Description of Informix Capital Stock -- Preferred Shares
Rights  Agreement." The  Board of  Directors has  the authority  to issue  up to
5,000,000 shares of Preferred  Stock (including the 350,000  shares of Series  A
Participating  Preferred)  in  one  or  more  series  and  to  fix  the  rights,
preferences, privileges and restrictions granted to or imposed upon any unissued
and undesignated  shares of  Preferred Stock  and to  fix the  number of  shares
constituting any series and the designations of such series, without any further
vote or action by the stockholders. Although it presently has no intention to do
so,   the  Board   of  Directors,   without  stockholder   approval,  can  issue

                                       89
<PAGE>
Preferred Stock with voting and  conversion rights which could adversely  affect
the  voting power or other  rights of the holders  of Informix Common Stock. The
issuance of  Preferred Stock  may  have the  effect  of delaying,  deferring  or
preventing  a change in  control of Informix.  Informix has no  present plans to
issue Preferred Stock.

    PREFERRED SHARES RIGHTS  AGREEMENT.   On September  17, 1991,  the Board  of
Directors  of Informix declared a dividend of one Preferred Stock Purchase Right
(a "Right")  for each  outstanding share  of Informix  Common Stock  issued  and
outstanding  on November 20,  1991, and authorized and  directed the issuance of
one Right  with respect  to each  share of  Informix Common  Stock that  becomes
outstanding prior to the occurrence of certain terminating events, pursuant to a
Preferred Shares Rights Agreement dated September 17, 1991, as initially amended
on  May 15,  1992 and subsequently  amended and  restated on July  25, 1995 (the
"Amended and Restated Rights Agreement"). The  holder of each share of  Informix
Common  Stock issued in  exchange for Illustra Common  Stock includes one Right.
Each Right entitles the registered holder to purchase from Informix 1/1000 of  a
share  of  Series A  Preferred Stock  at a  price equal  to $154.00,  subject to
adjustment under certain  circumstances provided in  the Rights Agreement.  Upon
the  occurrence  of  certain  events generally  associated  with  an unsolicited
attempt to  take  over  Informix, the  Rights  (except  for Rights  held  by  an
Acquiring  Person (as defined in the  Rights Agreement)) will become exercisable
and will cease  to trade with  the Informix Common  Stock. Upon the  acquisition
without  Board consent of 20% or more of Informix's Common Stock or announcement
of a tender  offer or  exchange offer for  shares in  excess of 20%  or more  of
Informix's  Common Stock,  each Right  (except for  Rights held  by an Acquiring
Person) will be converted into a right to purchase at the then-current  exercise
price  of the  Right that  number of  shares of  Informix Common  Stock having a
market value of two times the exercise price of the Right or, in the event of  a
merger  of Informix into an Acquiring Person, securities of the Acquiring Person
having a market value of two times  the exercise price of the Right. Subject  to
the terms of the Rights Agreement, Informix may exchange the Rights for Informix
Common Stock. The Rights have certain anti-takeover effects.

    The  Rights  will  cause substantial  dilution  to  a person  or  group that
attempts to  acquire Informix  in a  manner which  causes the  Rights to  become
exercisable.  Informix believes, however, that  the Rights should neither affect
any prospective offering  willing to negotiate  with the Board  of Directors  of
Informix nor interfere with any merger or other business combination approved by
the  Board of Directors of  Informix because the Board  of Directors may, at its
option, redeem the Rights. The terms of  the Rights may be amended by the  Board
of Directors of Informix without the consent of the holders of the Rights.

    TRANSFER  AGENT AND  REGISTRAR.   The Transfer  Agent and  Registrar for the
Informix Common Stock is The First  National Bank of Boston, 150 Royall  Street,
Canton, Massachusetts and its telephone number is (617) 575-3120.

DESCRIPTION OF ILLUSTRA CAPITAL STOCK

    The  authorized capital stock  of Illustra consists  of 20,000,000 shares of
Common Stock, $.0001 par value, and 13,000,000 shares of Preferred Stock, $.0001
par value,  1,300,000 shares  of which  are designated  as Series  A  Preferred,
7,760,000  shares of which are designated  as Series B Preferred, 844,444 shares
of which are designated as Series C Preferred, and 2,600,000 shares of which are

    COMMON STOCK.  As of the  Illustra Record Date, there were 4,321,663  shares
of  Illustra Common  Stock outstanding  and held  of record  by 85 stockholders.
Holders of  Illustra Common  Stock have  no preemptive  rights and  no right  to

of the Illustra Common Stock are validly issued, fully paid and nonassessable.
    

   
    PREFERRED STOCK.   As  of the  Illustra Record  Date, there  were  1,083,334
shares  of Series A  Preferred, 7,048,505 shares of  Series B Preferred, 844,444

                                       90
<PAGE>
   
shares of Series D  Preferred issued and  outstanding and held  of record by  38
stockholders. The principal rights, privileges and preferences of the issued and
outstanding shares of Illustra Preferred Stock are as set forth below.
    

    Dividends
    -------------   Holders of Illustra Preferred Stock are entitled to dividend
    preferences, when, as and if declared by the Illustra Board, at annual rates
of (i) $.075 per  share with respect  to shares of Series  A Preferred and  (ii)
$0.12 per share with respect to shares of Series B Preferred, Series C Preferred
and  Series D Preferred. All dividends  are non-cumulative. Illustra may not pay
cash dividends on Illustra Common Stock while there are any declared but  unpaid
cash dividends on any shares of Series A Preferred, Series B Preferred, Series C
Preferred or Series D Preferred outstanding.

    Liquidation
    --------------   In the event of  any liquidation, dissolution or winding up
    of Illustra (which, as defined  in Illustra's Certificate of  Incorporation,
would include the Merger) holders of the Series A Preferred, Series B Preferred,
Series  C Preferred and Series D Preferred are entitled to receive, prior and in
preference to  any distribution  of any  assets of  Illustra to  the holders  of
Illustra  Common Stock, $0.96,  $1.50, $2.25 and  $3.00 per share, respectively,
plus all accrued and unpaid dividends.  After the holders of Illustra  Preferred
Stock have received the full amount of their liquidation preference, the holders
of  Illustra  Common  Stock are  entitled  to  receive all  remaining  assets of
Illustra available for distribution, pro rata  based on the number of shares  of
Illustra Common Stock held by each.

    Conversion
    --------------   Each  share of Series  A Preferred, Series  B Preferred and
    Series D  Preferred is  presently  convertible into  one share  of  Illustra
Common  Stock,  subject to  anti-dilution adjustment  provisions. Each  share of
Series C Preferred is presently convertible  into three-fourths of one share  of
Illustra  Common Stock, subject to future  adjustment based on certain financial
performance criteria and subject to anti-dilution adjustment provisions.

    Certain Protective Provisions Applicable to Series C Preferred
    -------------------------------------------------------------   In  addition
    to  any  other rights  provided by  law or  agreement, so  long as  at least
700,000 shares of  Series C Preferred  shall be outstanding,  Illustra may  not,
without  first obtaining the affirmative vote  or written consent of the holders
of a majority of the  outstanding shares of the  Series C Preferred: (i)  Create
any  new  series or  class  of stock  having any  preference  or priority  as to
dividends or assets superior to any such preference or priority of the Series  C
Preferred;  (ii) Issue additional  shares of Series C  Preferred; or (iii) Amend
the Certificate of Incorporation to increase the number of authorized shares  of
Series C Preferred.

    VOTING  RIGHTS.   Subject to the  protective provisions  described above and
except as otherwise required by law, the holders of Series A Preferred, Series B
Preferred, Series C Preferred, Series D Preferred and Illustra Common Stock  are
entitled  to notice  of any  stockholders' meeting and  to vote  together as one
class upon any matter submitted to the stockholders for a vote on the  following
basis:

    (a)  COMMON VOTE. Each share of Illustra Common Stock issued and outstanding
has one vote.

    (b)   PREFERRED VOTE. Each holder of Series A Preferred, Series B Preferred,
Series C Preferred and  Series D Preferred  has a number of  votes equal to  the
number  of  full  shares  of  Illustra Common  Stock  into  which  such Illustra
Preferred Stock is then convertible.

                  COMPARISON OF RIGHTS OF HOLDERS OF INFORMIX
               COMMON STOCK AND HOLDERS OF ILLUSTRA CAPITAL STOCK

    Upon consummation of the  Merger, the holders of  Illustra Common Stock  and
the  holders of Illustra Preferred Stock  will become holders of Informix Common
Stock. As of  the Effective Time,  holders of Illustra  Preferred Stock will  no
longer  be entitled to certain rights  and privileges previously provided for in
Illustra's Certificate  of Incorporation.  Such rights  include (i)  a  dividend
preference  in the amounts described above, (ii) a liquidation preference in the
amounts described above, (iii)  certain anti-dilution adjustments upon  dilutive
issuances  of Illustra Capital Stock,  and (iv) the right  to vote as a separate
class concerning certain corporate transactions including the Merger.  Appraisal
and dissenters' rights are available to stockholders of Illustra with respect to
the  Merger. See "Approval  of the Merger and  Related Transactions -- Appraisal
and Dissenters' Rights."

    In addition, certain  other rights and  privileges of Illustra  stockholders
will  change  as a  result of  the Merger.  Upon completion  of the  Merger, the
percentage ownership of  Informix by  each former Illustra  stockholder will  be
substantially  less  than  his,  her  or  its  current  percentage  ownership of
Illustra. Accordingly, former  Illustra stockholders will  have a  significantly
smaller  voting influence over the affairs of Informix than they currently enjoy
over the affairs  of Illustra.  Moreover, certain  contractual rights  presently
possessed  by holders of Illustra Preferred Stock  will cease to exist after the
Merger. Specifically, certain information rights, registration rights, rights to
representation on, or  attendance at meetings  of the Illustra  Board and  other
rights  unique to the  organization and financing of  Illustra will terminate at
the Effective Time.  Finally, the  statutory protections  available to  Illustra
stockholders  under  Section  2115  of  the  CGCL  will  no  longer  exist.  See
"Applicability of California Law to Illustra."

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
Informix Corporation

    We  have audited  the accompanying  consolidated balance  sheets of Informix
Corporation as  of December  31, 1994  and 1993,  and the  related  consolidated
statements of income, stockholders' equity, and cash flows for each of the three
years  in the period ended December 31, 1994. These financial statements are the
responsibility of the Company's management. Our responsibility is to express  an
opinion on these financial statements based on our audits.

    We  conducted  our audits  in  accordance with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In  our opinion, the financial statements  referred to above present fairly,
in all  material  respects,  the consolidated  financial  position  of  Informix
Corporation  at December 31, 1994 and 1993,  and the consolidated results of its
operations and its cash flows  for each of the three  years in the period  ended
December 31, 1994 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1994, 1993 AND 1992
  (INFORMATION AS OF OCTOBER 1, 1995 AND FOR THE PERIODS ENDED OCTOBER 1, 1995
                       AND OCTOBER 2, 1994 IS UNAUDITED)

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    OPERATIONS.    Informix  Corporation, a  Delaware  corporation,  through its
wholly owned subsidiary  Informix Software,  Inc. and  its foreign  subsidiaries
(collectively  "the  Company"),  designs, develops,  manufactures,  markets, and
supports  distributed  relational  database  management  systems  (RDBMS),   and
object-oriented,  graphical and  character-based application  development tools,
and graphical data-access tools for  delivering information to most  significant
desktop  platforms.  In  addition  to  software  products,  the  Company  offers
training, consulting and maintenance to its customers.

    PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements  include
the  accounts of  Informix Corporation  and its  wholly owned  subsidiaries. All
material intercompany accounts, transactions,  and profits have been  eliminated
in consolidation.

    INTERIM  FINANCIAL  STATEMENTS    The  accompanying  unaudited  consolidated
financial statements as of October 1, 1995 and for the nine months ended October
1, 1995 and October 2, 1994, have been prepared on substantially the same  basis
as  the audited consolidated financial  statements, and include all adjustments,
consisting  only  of  normal  recurring   adjustments,  necessary  for  a   fair
presentation of the financial information set forth therein.

    FOREIGN  CURRENCY  TRANSLATION.    For  foreign  operations  with  the local
currency as the functional  currency, assets and  liabilities are translated  at
year-end  exchange rates, and statements of income are translated at the average
exchange  rates  during  the  year.  Exchange  gains  or  losses  arising   from
translation  of foreign currency denominated assets and liabilities are included
as a component of stockholders' equity.

    For foreign  operations with  the U.S.  dollar as  the functional  currency,
assets and liabilities are translated at the year-end exchange rates. Statements
of  income are translated at  the average exchange rates  during the year. Gains
and losses resulting  from foreign  currency translation are  included in  other
expense, net.

    The Company hedges, where possible, certain portions of its foreign exchange
transaction exposures to foreign currency fluctuations primarily through the use
of  forward foreign exchange contracts in European and Asian foreign currencies.
The Company  has limited  unhedged transaction  exposures in  certain  secondary
currencies in Latin America and Eastern Europe because there are limited forward
currency  exchange markets in these currencies. Gains and losses associated with
exchange rate fluctuations  on forward foreign  exchange contracts are  recorded
currently as income or loss as they offset corresponding gains and losses on the
foreign  currency denominated assets and liabilities  being hedged. The costs of
the forward foreign exchange contracts are  recorded as other expense, net.  See
Note 3 of Notes to Consolidated Financial Statements.

    REVENUE  RECOGNITION.  The Company generally recognizes license revenue from
sales of software licenses upon delivery of the software product to a  customer.
However, for certain computer hardware manufacturers and end-user licensees with
amounts  payable within twelve months, the Company will recognize revenue at the
time the customer makes  a contractual commitment  for a minimum  non-refundable
license fee, if such computer hardware manufacturers and end-user licensees meet
certain  criteria  established by  the Company.  License revenue  from resellers
(such as distributors and application vendors) and from other computer  hardware
manufacturers and end-users may be recognized at

media  on a per-unit basis.  However, in no case  is revenue recognized unless a
master or first copy is delivered to the customer.

    Maintenance contracts generally  call for the  Company to provide  technical
support  and  software updates  to  customers. Maintenance  contract  revenue is
recognized ratably over  the term of  the maintenance contract,  generally on  a
straight-line basis. Where maintenance revenue is not separately invoiced, it is
unbundled from license fees and deferred for revenue recognition purposes. Other
service  revenue, primarily training and  consulting, is generally recognized at
the time the service is performed.

    The  Company's  revenue  recognition  policy  is  in  compliance  with   the
provisions  of the American Institute of Certified Public Accountants' Statement
of Position 91-1, "Software Revenue Recognition."

    No single customer accounted for 10 percent or more of consolidated revenues
in 1994, 1993, or 1992.

    INCOME TAXES.  The Company accounts for income taxes in accordance with  the
provisions  of the Financial  Accounting Standards Board  Statement No. 109 (FAS
109) "Accounting for Income Taxes." Under FAS 109, the liability method is  used
in  accounting  for income  taxes. Under  this method,  deferred tax  assets and
liabilities are determined based on differences between the financial  reporting
and  income tax bases  of assets and  liabilities, and are  measured by applying
enacted tax rates and laws  to the taxable years  in which such differences  are
expected to reverse.

    INVENTORIES.    Inventories,  which consist  primarily  of  software product
components, finished software products, and marketing and promotional materials,
are carried at the lower of cost (first in, first out) or market value, and  are
included in other current assets.

    SOFTWARE COSTS.  The Company capitalizes software development costs incurred
in  developing a product once technological  feasibility of the product has been
determined. Software costs also include amounts paid for purchased software  and
outside  development on  products which have  reached technological feasibility.
All software costs are amortized as a cost of software distribution either on  a
straight-line basis over the remaining estimated economic life of the product or
on  the basis  of each product's  projected revenues, whichever  is greater. The
Company recorded amortization of $7.8 million, $5.2 million, and $5.7 million of
software costs  in 1994,  1993,  and 1992,  respectively,  in cost  of  software
distribution.

    PROPERTY   AND  EQUIPMENT.    Depreciation  of  property  and  equipment  is
calculated using  the  straight-line  method over  the  estimated  useful  life,
generally  the shorter of the  lease term or three  to seven years for financial
reporting purposes, and by accelerated methods for tax purposes.

    BUSINESSES ACQUIRED.  The purchase price of businesses acquired is allocated
to the tangible and specifically  identifiable intangible assets acquired  based
on  their  fair values  with  any amount  in  excess of  such  allocations being
designated as goodwill.  Intangible assets  are amortized  over their  estimated
useful  lives,  which  to  date  have been  five  to  seven  years.  The Company
periodically monitors the recoverability of such intangible assets.

                        DECEMBER 31, 1994, 1993 AND 1992
  (INFORMATION AS OF OCTOBER 1, 1995 AND FOR THE PERIODS ENDED OCTOBER 1, 1995
                       AND OCTOBER 2, 1994 IS UNAUDITED)

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    NET INCOME PER COMMON SHARE.   Net income per common  share is based on  the
weighted  average  number  of  common  and  dilutive  common  equivalent  shares
outstanding during each year. All  stock options and convertible debentures  are
considered  common stock  equivalents and are  included in  the weighted average
computations when the effect is dilutive.

    STOCK SPLIT.  All  share and per share  amounts applicable to prior  periods
have been restated to reflect a two-for-one stock split (effected in the form of
a stock dividend) which was effective June 26, 1995.

    CONCENTRATION  OF CREDIT RISK.  The Company designs, develops, manufactures,
markets, and  supports computer  software systems  to customers  in  diversified
industries and in diversified geographic locations. The Company performs ongoing
credit  evaluations of its customers' financial condition and generally requires
no collateral.

    CASH,   CASH    EQUIVALENTS,    SHORT-TERM   INVESTMENTS    AND    LONG-TERM
INVESTMENTS.    The  Company  considers  liquid  investments  purchased  with an
original maturity of three  months or less to  be cash equivalents. The  Company
considers  investments with an  original maturity of more  than three months but
less than one year  to be short-term investments.  Investments with an  original
maturity  of more than one year are considered long-term investments. Short-term
and long-term investments are carried at  either amortized costs or fair  value,
depending  on  their classification  as held-to-maturity  or available-for-sale,
respectively. Cash equivalents are carried at amortized costs.

    The Company invests its  excess cash in accordance  with its short-term  and
long-term  investments policy which  is approved by the  Board of Directors. The
policy authorizes  the  investment  of excess  cash  in  government  securities,
municipal  bonds, time deposits, certificates of deposit with approved financial
institutions, commercial paper rated A-1/P-1  (a small portion of the  portfolio
may  consist of commercial paper rated A-2/P-2), and other specific money market
instruments of  similar  liquidity  and  credit quality.  The  Company  has  not
experienced any significant losses related to these investments.

    SECURITIES  HELD-TO-MATURITY AND AVAILABLE-FOR-SALE.   Management determines
the appropriate classification of  debt securities at the  time of purchase  and
re-evaluates such designation as of each balance sheet date. Debt securities are
classified  as held-to-maturity when the Company has the positive intent and the
ability to hold the securities  until maturity. Held-to-maturity securities  are
stated at amortized cost, adjusted for amortization of premiums and accretion of
discounts  to  maturity.  Such amortization,  as  well  as any  interest  on the
securities, is included in interest income.

    Marketable  equity  securities  and   debt  securities  not  classified   as
held-to-maturity   are  classified   as  available-for-sale.  Available-for-sale
securities are carried at fair value, with the unrealized gains and losses,  net
of  tax, reported in a separate component of stockholders' equity. The amortized
cost of  debt  securities in  this  category  is adjusted  for  amortization  of
premiums  and accretion of discounts to  maturity. Such amortization is included
in interest income. Realized gains and losses and declines in value judged to be
other-than-temporary on  available-for-sale  securities are  included  in  other
expense,   net.  The  cost   of  securities  sold  is   based  on  the  specific
identification method. Interest on  securities classified as  available-for-sale
are included in interest income.

NOTE 2 -- FAIR VALUES OF FINANCIAL INSTRUMENTS
    Effective   January  1,  1994,  the  Company  adopted  Financial  Accounting
Standards Board Statement No. 115,  "Accounting for Certain Investments in  Debt
and Equity Securities" (FAS 115).

    Due  to insignificant differences at the date of adoption of FAS 115 between
the cost and  fair value  of the  Company's investments,  when considering  both
gross  unrealized gains and gross unrealized losses, the adoption of FAS 115 had
no effect on  the Company's  financial statements.  Consequently, in  accordance
with FAS 115, prior period financial statements have not been restated.

    The  fair  values for  marketable debt  and equity  securities are  based on
quoted market prices.

    The  following   is   a   summary   of   held-to-maturity   securities   and
available-for-sale securities at December 31, 1994:

NOTE 3 -- DERIVATIVE FINANCIAL INSTRUMENTS
    Effective  January 1, 1994, the Company  adopted the provisions of Financial
Accounting Standards  Board  Statement  No. 119,  "Disclosure  about  Derivative
Financial Instruments and Fair Value of Financial Instruments" (FAS 119).

    The  Company enters  into forward  foreign exchange  contracts to  hedge the
value of recorded foreign currency denominated transactions against fluctuations
in exchange  rates.  The purpose  of  the Company's  foreign  exchange  exposure
management policy and practices is to attempt to minimize the impact of exchange
rate  fluctuations on the  value of the foreign  currency denominated assets and
liabilities being hedged. Substantially  all forward foreign exchange  contracts
entered into by the Company have maturities of 360 days or less. At December 31,
1994  and 1993, the Company had approximately $94.3 million and $29.3 million of
forward foreign exchange  contracts outstanding, respectively.  The table  below
summarizes  by currency the contractual amounts of the Company's forward foreign
exchange contracts at December 31, 1994 and December 31, 1993.

NOTE 3 -- DERIVATIVE FINANCIAL INSTRUMENTS (CONTINUED)
    Other than  the  use of  forward  foreign exchange  contracts  as  discussed
immediately  above, the Company does  not currently invest in  or hold any other
financial instruments defined as derivative financial instruments by FAS 119.

NOTE 4 -- EMPLOYEE STOCK OPTION AND PURCHASE PLANS
    Under the Company's 1986 Employee Stock Option Plan, options are granted  at
fair market value on the date of the grant. Options are generally exercisable in
cumulative  annual installments  over three  to five  years. Payment  for shares
purchased upon exercise of options  may be by cash  or, with Board approval,  by
full  recourse promissory note or by exchange  of shares of the Company's common
stock at fair market value on the  exercise date. Options expire 10 years  after
the  date of grant. At December 31,  1994, 40,800,000 shares were authorized for
issuance under the Plan.

    Additionally, 1,600,000 shares were authorized  for issuance under the  1989
Outside   Directors  Stock  Option  Plan,  whereby  non-employee  directors  are
automatically granted non-qualified stock  options upon election or  re-election
to the Board of Directors.

    Following is a summary of activity for both stock option plans for the three
years ended December 31, 1994:

    In  April 1994, the  Company adopted the  1994 Stock Option  and Award Plan.
Options can be granted to employees  on terms substantially equivalent to  those
described above. The 1994 Stock Option and Award Plan also allows the Company to
award  performance shares of the Company's common stock to be paid to recipients
on the  achievement  of certain  performance  goals  set with  respect  to  each
recipient.  At December 31, 1994, 8,000,000 shares were authorized for issuance,
but no options have been granted to date under this plan.

    In connection with all stock option plans, 22,915,600 shares of common stock
were reserved for issuance  as of December  31, 1994. At  December 31, 1994  and
1993, options exercisable were 4,684,724 and 3,080,074, respectively.

NOTE 4 -- EMPLOYEE STOCK OPTION AND PURCHASE PLANS (CONTINUED)
    The  Company also has  a qualified Employee Stock  Purchase Plan under which
7,600,000 shares  of common  stock in  the aggregate  have been  authorized  for
issuance.  Under the  terms of  the Plan,  employees may  contribute via payroll
deductions up to 10 percent  of their base pay and  purchase up to 1,000  shares
per quarter (with the limitation of purchases of $25,000 annually in fair market
value  of the shares). Employees may elect  to withdraw from the Plan during any
quarter and have  their contributions  for the  period returned  to them.  Also,
employees may elect to reduce the rate of contribution one time in each quarter.
The  price at which employees may purchase shares  is 85 percent of the lower of
the fair market value of the stock at  the beginning or end of the quarter.  The
Plan  is qualified under  Section 423 of  the Internal Revenue  Code of 1986, as
amended. During 1994, 1993, and 1992 the Company issued 484,756 shares,  395,102
shares,  and 665,932 shares,  respectively, under this  Plan. In connection with
the Employee Stock Purchase Plan, 1,614,458 shares were reserved for issuance as
of December 31, 1994.

    The Board of Directors has authorized the purchase of up to 8 million shares
of the Company's common stock in  the open market to satisfy requirements  under
Stock  Option and Stock Purchase Plans. Such  shares are recorded using the cost
method and are reissued using the first-in, first-out (FIFO) method. During 1994
and 1993, approximately 2,600,000  shares and 980,000  shares with an  aggregate
cost  of approximately $22.1  million and $10.0  million, respectively, had been
repurchased on  the  open market.  All  such shares  have  been reissued  as  of
December 31, 1994.

NOTE 5 -- 401(K) PLAN
    The  Company  has  a 401(k)  plan  covering  substantially all  of  its U.S.
employees. Under this plan, participating employees  may defer up to 15  percent
of  their  pre-tax  earnings, subject  to  the Internal  Revenue  Service annual
contribution limit ($9,240 for 1994). In 1994, the Company matched 50 percent of
each employee's contribution up to a  maximum of $1,500. The Company's  matching
contributions  to this 401(k) plan  for 1994, 1993, and  1992 were $1.4 million,
$0.8 million, and $0.3 million, respectively.

</TABLE>

    Cumulative undistributed  earnings of  the  Company's Irish  subsidiary  for
which  no income taxes have been provided aggregated approximately $11.4 million
at December 31, 1994. These earnings are considered to be permanently reinvested
in non-U.S. operations.  Additional taxes  of approximately  $2.9 million  would
have to be provided if these earnings were repatriated to the U.S.

    At  December 31, 1994 the Company  had approximately $8.0 million of foreign
net operating  loss carryforwards  which expire  at various  dates beginning  in
1999. Income taxes paid amounted to $22.5 million, $7.8 million and $3.1 million
in 1994, 1993 and 1992, respectively.

    The deferred tax asset valuation allowance increased by $0.9 million in 1994
and  decreased $9.9  million and  $5.0 million  in 1993  and 1992, respectively.
Approximately $8.9  million of  the 1993  valuation allowance  decrease of  $9.9
million was related to tax carryforwards attributable to stock option deductions
which was credited to paid-in capital.

NOTE 9 -- LITIGATION
    On  May 10,  1993, the Company  settled the securities  class action lawsuit
filed against the Company and certain of its officers and directors in 1988. The
Company provided a charge  of $10.5 million  in the fourth  quarter of 1992  for
such settlement and related costs.

    The  settlement does not constitute an  admission of liability or wrongdoing
on the part  of the  Company or  on the part  of any  of its  current or  former
officers  and  directors.  The  settlement  does  represent  a  decision  by the
Company's Board of  Directors that  a settlement  at the  time was  in the  best
interest of the Company and its stockholders.

    In  the ordinary course  of business, various lawsuits  and claims are filed
against the Company.  It is the  Company's opinion that  the resolution of  such
litigation  will not have a material effect on the Company's financial position,
results of operations, or cash flows.

NOTE 10 -- BUSINESS COMBINATIONS
    In July  1994,  the  Company  acquired  the business  of  a  division  of  a
distributor  of its products in Germany. This acquisition has been recorded as a
purchase. The purchase cost of this business was approximately $10.6 million, of
which $4.8 million was allocated to intangible assets acquired.

    In August 1994, the  Company acquired the business  of a distributor of  its
products in Malaysia. This acquisition has also been recorded as a purchase. The
purchase  cost of  this business was  approximately $1.9 million,  of which $1.8
million was allocated to intangible assets acquired. An additional $1.0  million
consideration  may be payable by the  Company contingent upon the achievement of
certain financial objectives by the business.

    In January 1995, the Company acquired a 90 percent interest in the  database
division  of  ASCII Corporation,  a distributor  of its  products in  Japan. The
Company will acquire the remaining 10 percent in January 1996. This  acquisition
has  been accounted for as  a purchase. The purchase  price of this business was
approximately $46.0  million,  of which  $34.8  million has  been  allocated  to
intangible  assets acquired  which are being  amortized over  a weighted average
life of seven years.

    In April 1995, the Company acquired  an 80 percent interest in the  database
division  of  Daou Corporation,  a  distributor of  its  products in  Korea. The
Company will acquire the remaining 20 percent by January 1997. This  acquisition
has  been accounted for as  a purchase. The purchase  price of this business was
approximately $4.3  million,  of  which  $4.0  million  has  been  allocated  to
intangible  assets acquired  which are being  amortized over  a weighted average
life of seven years.

    The operating results of these businesses have not been material in relation
to those of the Company and  are included in the Company's consolidated  results
of operations from the date of acquisition.

NOTE 12 -- SUBSEQUENT EVENTS
    In  October 1995,  the Company acquired  Stanford Technology  Group (STG), a
U.S.-based company that provides  on-line analytical processing technology,  for
approximately  570,000  shares  of its  common  stock. The  transaction  will be
accounted for as a pooling of interests. Since the operating results of STG  are
insignificant  to  the  Company,  prior period  annual  and  quarterly financial
statements of  the  Company will  not  be  restated for  this  transaction.  The
Company's  results  of operations  for  the year  ended  December 31,  1995 will
include the results of  operations of STG  for such year, all  of which will  be
recorded in the fourth quarter.

    In  December 1995, the Company entered into an agreement to acquire Illustra
Information Technologies, Inc.  (Illustra), a U.S.-based  company that  provides
dynamic  content management systems and tools for applications in multimedia and
entertainment,  digital  media   publishing,  and  financial   services,  in   a
transaction  that will  be accounted  for as a  pooling of  interests. Under the
terms of the agreement, the Company  will issue 15,000,000 shares of its  common
stock,  less the shares  reserved for all of  Illustra's outstanding options and
warrants, in exchange for all of  the outstanding common and preferred stock  of
Illustra. Expenses related to this merger are expected to approximate $5 million
and  will be recorded  in the quarter  in which the  transaction is consummated,
currently expected to be during the first quarter of 1996.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
Illustra Information Technologies, Inc. and Subsidiary:

    We have audited  the accompanying  consolidated balance  sheets of  Illustra
Information  Technologies, Inc. and subsidiary (the Company) as of June 30, 1995
and 1994, and the related  consolidated statements of operations,  stockholders'
equity, and cash flows for the years then ended and for the period from July 31,
1992  (inception) to June 30, 1993.  These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.

    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our  opinion, the  consolidated financial  statements referred  to  above
present  fairly, in  all material respects,  the financial  position of Illustra
Information Technologies, Inc. and subsidiary as of June 30, 1995 and 1994,  and
the  results of their operations  and their cash flows  for the years then ended
and for  the  period  from July  31,  1992  (inception) to  June  30,  1993,  in
conformity with generally accepted accounting principles.

NOTE (1) -- DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES

    DESCRIPTION OF BUSINESS

   
    Illustra  Information Technologies,  Inc. and  subsidiary (the  Company) was
incorporated in the  state of Delaware  in July  1992 to engage  in the  design,
development, and marketing of object-relational database management systems.
    

   
    MERGER WITH SUBSIDIARY OF INFORMIX CORPORATION
    

   
    On  December 20,  1995, the  Company entered into  an Agreement  and Plan of
Reorganization providing for  the merger  of the  Company with  a subsidiary  of
Informix  Corporation (Informix).  Under the terms  of the  proposed merger, the
Company will exchange all of its then outstanding (and certain committed) shares
of capital stock, options,  and warrants for a  maximum of 15,000,000 shares  of
Informix  common stock.  If the requisite  approvals of the  stockholders of the
Company are received, the merger is expected to be consummated in February 1996.
    

    PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial  statements include the accounts  of
the   Company   and  its   wholly   owned  subsidiaries,   Illustra  Information
Technologies, Ltd. and Illustra Information Technologies S.A. (August 1995). All
significant intercompany  balances  and  transactions have  been  eliminated  in
consolidation.

    FOREIGN CURRENCY TRANSLATION

    The  functional currency of the Company's  foreign subsidiaries is the local
currency.  Assets  and  liabilities  denominated  in  the  local  currency   are
translated  to U.S.  dollars at  the exchange  rate on  the balance  sheet date.
Revenues, costs  and  expenses  are  translated at  average  rates  of  exchange
prevailing  during the year. Translation adjustments resulting from this process
are shown separately in stockholders' equity. Foreign currency transaction gains
and losses are included in net loss.

    As of June 30, 1995, no material assets are located in nor have any material
operating results been generated in foreign jurisdictions.

    CASH AND CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

    The Company  adopted the  provisions of  Statement of  Financial  Accounting
Standards  (SFAS) No. 115, ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY
SECURITIES, for investments held as of or acquired after July 1, 1994. Under the
provisions of  SFAS No.  115,  the Company  has  classified its  investments  as
"available-for-sale."   Such  investments  are  recorded  at  fair  value,  with
unrealized gains and losses  reported as a  separate component of  stockholders'
equity.  In  accordance  with  the  provisions of  SFAS  No.  115,  prior period
consolidated financial statements have not  been restated to reflect the  change
in  accounting principle. The cumulative effect of adopting SFAS No. 115 was not
material to  the  Company's  consolidated  financial  position  and  results  of
operations.

    Realized  gains and losses,  and declines in  value judged to  be other than
temporary on available-for-sale securities are included in other income, net  on
the  accompanying consolidated statements of  operations. The cost of securities
sold is based on the specific  identification method. Interest and dividends  on
securities  classified as  available-for-sale are  included in  interest income,
net.

NOTE (1) -- DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES (CONTINUED)
    REVENUE RECOGNITION

    Revenue under product license agreements is recognized upon delivery.  Costs
of software distribution primarily include product packaging, documentation, and
software media.

    Services  revenues primarily  consist of maintenance,  and customer training
and consulting services, and development  contract fees. Maintenance revenue  is
deferred  and recognized  ratably over  the term  of the  maintenance agreement,
which is typically 12  months. Revenue for customer  training and consulting  is
recognized  as the services  are performed. Revenue  on development contracts is
recognized based upon achievement of specified milestones.

    Deferred revenue  is  recorded  on  billed  product  licenses,  maintenance,
training,  and  consulting  efforts  for  which  performance  is  incomplete  or
significant vendor obligations exist.

    PROPERTY AND EQUIPMENT

    Property and equipment are  recorded at cost.  Depreciation of property  and
equipment  is provided over  the estimated useful life  of the respective assets
(generally three to  five years)  using the straight-line  method. Property  and
equipment recorded under capital leases and leasehold improvements are amortized
on  a straight-line basis  over the shorter  of the lease  term or the estimated
useful life of the asset.

    SOFTWARE DEVELOPMENT COSTS

    Development costs incurred in the  research and development of new  software
products  are  expensed as  incurred  until technological  feasibility  has been
established. No costs have been capitalized to date.

    INCOME TAXES

    The Company uses the asset and liability method of comprehensive interperiod
income tax accounting  pursuant to SFAS  No. 109, ACCOUNTING  FOR INCOME  TAXES.
Under  SFAS No. 109, deferred tax assets  and liabilities are recognized for the
future tax  consequences  attributable  to  differences  between  the  financial
statement  carrying  amounts  of  existing  assets  and  liabilities  and  their
respective tax bases.  Deferred tax  assets and liabilities  are measured  using
enacted  tax rates  expected to apply  to taxable  income in the  years in which
those temporary differences are expected to be recovered or settled. The  effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date.

    PRO FORMA NET LOSS PER SHARE

    Pro  forma net  loss per  share is  computed based  on the  weighted average
number of shares of common stock  outstanding and common equivalent shares  from
stock  options and warrants  (under the treasury stock  method, if dilutive) and
preferred  stock  outstanding   (on  an   "as-if  converted"   basis,  even   if
antidilutive).

    INTERIM FINANCIAL STATEMENTS

   
    The  accompanying unaudited  consolidated financial  statements for  the six
months ended December 31, 1995 and 1994, have been prepared on substantially the
same basis as  the audited  consolidated financial statements,  and include  all
adjustments,  consisting only of  normal recurring adjustments,  necessary for a
fair presentation of the financial information set forth therein.

NOTE (5) -- PREFERRED STOCK

    PREFERRED STOCK TRANSACTIONS

    In  April  1994, the  Company converted  all  of its  previously outstanding
Series C preferred stock into shares  of the Company's Series B preferred  stock
at a conversion price of $1.50 per share (or approximately 1.67 shares of Series
B  preferred stock for each share of Series C preferred stock). As a result, all
1,052,263 shares  of  previously  outstanding  Series  C  preferred  stock  were
converted to 1,753,767 shares of Series B preferred stock.

    In  April 1994, by operation of the pro rata investment provisions discussed
below, 361,792 and 151,737 shares of Series B and previously outstanding  Series
C  preferred stock, respectively, were converted  into an equal number of shares
of common stock.

    In April 1994, the  Company entered into an  agreement with one investor  to
exchange  193,195 shares of common stock for an equal number of shares of Series
B preferred stock and to repurchase  the investor's remaining 158,300 shares  of
common stock.

   
    In  November 1994,  the Company  sold 844,444  shares of  Series C preferred
stock to an investor who held the right to put the shares back to the Company if
certain  Company  development  milestones  were  not  met.  The  put  price  was
established as the higher of: (i) the price the investor initially paid plus any
declared  but unpaid  dividends thereon,  or (ii)  the then  current fair market
value. In September 1995,  the Company achieved  the development milestones  and
the  put right was terminated by its  terms, whereupon the liquidation value was
reclassified to stockholders' equity.
    

   
    In November 1995, the  Company issued 177,250 shares  of Series D  preferred
stock for gross proceeds of $531,750.
    

    RIGHTS AND PREFERENCES:

    - Holders  of preferred stock are entitled to noncumulative annual dividends
      of $0.075,  $0.12, $0.12  and $0.12  per share  of Series  A, B,  C and  D
      preferred  stock,  respectively,  when and  if  declared by  the  Board of
      Directors.

    - Holders of preferred stock have a liquidation preference of $0.96,  $1.50,
      $2.25  and  $3.00 per  share  of Series  A, B,  C  and D  preferred stock,
      respectively, plus all declared but unpaid dividends. Any remaining assets
      shall be distributed ratably among the common stockholders.

    - Each share of preferred  stock has voting rights  on an "as if  converted"
      basis.

    - Each  share of Series A, B, and  D preferred stock is convertible into one
      share of  common  stock  subject  to  certain  adjustments  for  dilution.
      Outstanding  Series C preferred stock is convertible into shares of common
      stock based on a conversion factor which adjusts according to fiscal  1995
      and 1996 revenues.

    - Each  share of preferred  stock will automatically  be converted to common
      stock upon the  earlier of the  closing of an  initial public offering  or
      upon  the written consent to such conversion  by the holders of a majority
      of Series A, Series B and Series D preferred stock and the written consent
      to such conversion by the holders of a majority of the Series C  preferred
      stock.

NOTE (5) -- PREFERRED STOCK (CONTINUED)
    - Preferred  stock  investors who  do  not invest  their  pro rata  share in
      subsequent preferred stock rounds may  be subject to automatic  conversion
      of  preferred stock to common stock based on the decline in their pro rata
      share.

    - The holders of preferred  stock have a right  of first refusal to  acquire
      any new securities issued by the Company.

    - The  holders of outstanding Series C preferred stock have the right to put
      their shares back to the Company, as described above.

NOTE (6) -- COMMON STOCK
    From inception through June 30, 1995, the Company issued 2,546,500 shares of
common  stock to  employees and directors  which are subject  to repurchase. The
Company's repurchase right to such shares expires as shares vest, generally  20%
to 25% following the first year of employment with the remainder vesting ratably
over the following three to four years. As of June 30, 1995, 1,168,790 shares of
common stock were subject to repurchase.

    The  Company may  not pay  cash dividends  on common  stock while  there are
declared but unpaid cash dividends on any shares of Series A preferred, Series B
preferred, Series C preferred or Series D preferred stock outstanding.

   
    As of June  30, 1995,  employees had  exercised options  to purchase  41,312
shares of common stock (Note 7) prior to the options having vested. These shares
are  subject to repurchase  by the Company if  an employee terminates employment
before the options vest.
    

    In April  1995, the  Company reserved  214,500 shares  of common  stock  for
issuance  to certain employees as performance  awards. The shares may be awarded
to these employees through June 1996, at up to a maximum of 20% each quarter, by
meeting specified operational goals. As  of June 30, 1995, targeted  operational
goals  had been met, and in July 1995, the Board of Directors granted options to
purchase 42,900 shares of common stock to the employees.

NOTE (7) -- OPTION PLANS
    In 1992, the Board of Directors adopted an Equity Incentive Plan (the  Plan)
providing  for the issuance of common stock options to employees, directors, and
consultants of  the  Company.  The  stock options  are  a  combination  of  both
incentive and nonstatutory stock options.

    EMPLOYEE BENEFITS

    The Company maintains a 401(k) defined contribution benefit plan that covers
all employees who  have completed  at least 1,000  hours of  service. This  plan
allows  employees to defer  up to 15% of  their pretax salary,  up to $9,240, in
certain investments at the election of the employee. The Company has the  option
to  make discretionary employer matching contributions. The Company did not make
any matching contributions to the plan during the years ended June 30, 1995  and
1994.

    LITIGATION

    The  Company is a party to a lawsuit in which one of its competitors alleges
intentional interference with contractual relationships, unfair competition, and
conspiracy arising out  of the  Company's alleged improper  solicitation of  the
competitor's   employees  for  employment  with  the  Company.  The  suit  seeks
unspecified restitution, compensatory and punitive damages, attorneys' fees, and
costs of the suit.  The Company believes  the claim to be  without merit and  is
vigorously defending the suit.

</TABLE>

    As of June  30, 1995, the  Company has net  operating loss carryforwards  of
approximately  $12,000,000 and  $3,000,000 for federal  and California purposes,
respectively. The Company also has research and development credit carryforwards
of approximately  $600,000 and  $200,000 for  federal and  California  purposes,
respectively.  The  federal net  operating  loss carryforwards  and  federal and
California  research  credit  carryforwards  expire  from  2008  to  2010.   The
California net operating loss carryforwards expire from 1998 to 2001.

    The  Company experienced an "ownership change," as defined by Section 382 of
the Internal Revenue Code, in the fiscal  year ended June 30, 1993. As a  result
of  this ownership change,  $800,000 and $400,000 of  the federal and California
net operating  loss  carryforwards,  respectively, are  subject  to  limitation.
Research  and  development  credit  carryforwards  for  federal  and  California
purposes of $50,000 and $20,000,  respectively, are also subject to  limitation.
The  limitation allows the Company to  utilize approximately $75,000 annually of
"pre-ownership change" net  operating loss carryforwards  or credit  equivalents
subsequent  to June 30, 1994.  This annual limitation may  be carried forward to
subsequent years if not used.

   
    The proposed merger with  Informix will result  in an additional  "ownership
change"  pursuant  to  Section  382  of  the  Internal  Revenue  Code.  However,
management believes that there  will be no further  "Section 382 limitation"  on
available net operating loss carryforwards described above.

period  from July  31, 1992  (inception) to  June 30,  1993 have  primarily been
derived from customers in North America.

    DEFERRED REVENUE

    In January  1995, the  Company entered  into an  International  Distribution
Agreement  (Distribution Agreement) with a  Japanese value-added reseller (VAR).
Under this Distribution  Agreement, the  Company granted  the VAR  a license  to
market and sublicense the Company's software in Japan. The companies also agreed
that  the  localization of  the Illustra  Server and  certain Datablades  to the
Japanese market shall be a joint development effort. In exchange for the product
license and  development assistance,  the Company  received $2,000,000  in  cash
which  has  been recorded  as  deferred revenue.  The  VAR also  made  an equity
investment of $2,000,000 for which the Company issued 666,667 shares of Series D
preferred stock. As of June 30, 1995, sales in connection with the  Distribution
Agreement have been minimal.

    In  April 1995, the Company entered into a License, Support, and Maintenance
Agreement with  a domestic  customer  in which  the  Company agreed  to  license
certain  software products  to be  embedded in  or combined  with the customer's
products, during an initial  two-year period. As of  June 30, 1995, the  Company
has  deferred  approximately $1,200,000  in  license fees  associated  with this
contract.

   
    In June 1995, the Company entered into a Software Development, License,  and
Maintenance  Agreement with a  domestic customer in which  the Company agreed to
port certain  software products  to the  customer's platform.  The Company  also
granted  the customer  the right  to sublicense the  software to  end users, for
which the Company will receive royalties. As  of June 30, 1995, the Company  has
deferred  approximately  $750,000  in  prepaid  royalties  associated  with this
contract.

<PAGE>
                      AGREEMENT AND PLAN OF REORGANIZATION

    This  AGREEMENT AND  PLAN OF REORGANIZATION  (this "AGREEMENT")  is made and
entered into as  of December  20, 1995  among Informix  Corporation, a  Delaware
corporation  ("PARENT"), Informix Delaware,  Inc., a Delaware  corporation and a
wholly-owned subsidiary  of  Parent  ("MERGER SUB"),  and  Illustra  Information
Technologies, Inc., a Delaware corporation (the "COMPANY").

                                    RECITALS

    A.   The Boards of  Directors of each of the  Company, Parent and Merger Sub
believe it  is  in the  best  interests of  each  company and  their  respective
stockholders  that Parent  acquire the Company  through the  statutory merger of
Merger Sub with and into the Company (the "MERGER") and, in furtherance thereof,
have approved the Merger.

    B.  Pursuant to the Merger, among other things, and subject to the terms and
conditions of  this Agreement,  all  of the  issued  and outstanding  shares  of
capital  stock  of the  Company ("COMPANY  CAPITAL  STOCK") and  all outstanding
options, warrants  and other  rights to  acquire or  receive shares  of  Company
Capital  Stock shall  be converted  into the right  to receive  shares of Common
Stock of Parent ("PARENT COMMON STOCK").

    C.  A portion  of the shares  of Parent Common  Stock otherwise issuable  by
Parent  in connection with the  Merger shall be placed  in escrow by Parent, the
release of which amount shall be contingent upon certain events and  conditions,
all as set forth in Article VII hereof.

    D.     The   Company,  Parent  and   Merger  Sub  desire   to  make  certain
representations and  warranties  and other  agreements  in connection  with  the
Merger.

    NOW,   THEREFORE,   in  consideration   of   the  covenants,   promises  and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby the parties agree as follows:

                                   ARTICLE I
                                   THE MERGER

    1.1  THE  MERGER.  At  the Effective Time  (as defined in  Section 1.2)  and
subject  to  and  upon  the  terms and  conditions  of  this  Agreement  and the
applicable provisions of the Delaware  General Corporation Law ("DELAWARE  LAW")
and  the California General Corporation Law ("CALIFORNIA LAW"), Merger Sub shall
be merged with and into the Company, the separate corporate existence of  Merger
Sub  shall cease and the Company shall continue as the surviving corporation and

acceptance by the Secretary of State  of Delaware of such filing being  referred
to  herein  as the  "EFFECTIVE  TIME"). The  parties  currently intend  that the
Closing Date will occur on or prior to February 29, 1996.

           audited   financial  statements   for  the  1996   fiscal  year  (the
           "CONVERSION CALCULATION  DATE"),  the  number of  shares  of  Company
           Common  Stock that shall be deliverable upon conversion of a share of
           Series C Preferred provisionally shall be deemed to be a fixed amount
           (the "CONVERSION AMOUNT"), and the Conversion Amount shall be subject
           to increase  based  on  events  that would  be  determinable  on  the
           Conversion  Calculation  Date (the  Company  Common Stock  that would
           constitute an increase to the Conversion Amount per share of Series C
           Preferred is  hereinafter referred  to as  the "SERIES  C  ADDITIONAL
           CONVERSION  SHARE",  and  thus  one  right  to  receive  a  Series  C
           Additional Conversion Share  would be outstanding  for each share  of
           Series  C Preferred that is converted into Company Common Stock prior
           to the Conversion Calculation Date).  Based on the foregoing, in  the
           event  that  the  Effective  Time  occurs  prior  to  the  Conversion
           Calculation Date,  then by  virtue of  the Merger,  each  outstanding
           right  to receive a Series  C Additional Conversion Share immediately
           prior to the Effective Time will be canceled and extinguished and  be
           converted  automatically  into the  right to  receive that  number of
           shares of  Parent Common  Stock equal  to the  Additional  Conversion
           Share  Exchange  Ratio  (as  defined in  paragraph  (i)  below), upon
           surrender of a certificate (or other evidence reasonably satisfactory
           to  Parent  or  the  Exchange  Agent)  representing  such  Series   C
           Additional  Conversion Share in  the manner provided  in Section 1.8,

       and extinguished and be converted automatically into the right to receive
       that number  of shares  of Parent  Common  Stock equal  to the  Series  D
       Exchange Ratio (as defined in paragraph (i) below), upon surrender of the
       certificate  representing such share of Series  D Preferred in the manner
       provided in Section 1.8, including, with  respect to each whole share  of
       Parent Common Stock to be received, one Right.

       (c)  CANCELLATION OF PARENT-OWNED AND COMPANY-OWNED STOCK.  Each share of
       Company  Capital Stock  owned by Merger  Sub, Parent, the  Company or any
    direct or  indirect wholly-owned  subsidiary  of Parent  or of  the  Company

       under  this Agreement shall continue to have, and be subject to, the same
       terms and conditions set forth in  the Option Plan and/or as provided  in
       the   respective   option  agreements   governing  such   Company  Option
       immediately prior to  the Effective  Time, except that  (A) such  Company
       Option  shall be  exercisable for that  number of whole  shares of Parent
       Common Stock equal  to the  product of the  number of  shares of  Company
       Common  Stock that  were issuable  upon exercise  of such  Company Option
       immediately prior to the Effective Time multiplied by the Common Exchange
       Ratio, rounded down  (in the case  of Company Options  granted under  the
       Option Plan) to the nearest whole number of shares of Parent Common Stock
       and  (B) the  per share  exercise price for  the shares  of Parent Common
       Stock issuable  upon exercise  of such  assumed Company  Option shall  be
       equal to the quotient determined by dividing the exercise price per share
       of  Company Common  Stock at  which such  Company Option  was exercisable
       immediately prior to  the Effective  Time by the  Common Exchange  Ratio,
       rounded up to the nearest whole cent.

           (ii)  It is  the intention  of the  parties that  the Company Options
       assumed by Parent qualify following the Effective Time as incentive stock
       options as defined in Section 422 of  the Code to the extent the  Company
       Options  qualified as  incentive stock  options immediately  prior to the
       Effective Time.

          (iii) Promptly following the Effective Time, Parent will issue to each
       holder of  an  outstanding  Company  Option  a  document  evidencing  the
       foregoing assumption of such Company Option by Parent.

       (e)   WARRANTS.   Each  warrant to  purchase shares  of Company Preferred
       Stock outstanding at the Effective Time shall be, in connection with  the
    Merger,  assumed by  Parent. Each  warrant so  assumed by  Parent under this
    Agreement shall continue  to have,  and be subject  to, the  same terms  and
    conditions  set forth  in the  respective warrant  agreements governing such
    warrant immediately  prior to  the  Effective Time,  except that  each  such
    warrant  shall, following the Effective Time, be exercisable only for shares
    of Parent Common Stock,  in such number,  and at such  exercise price as  is
    determined by applying the appropriate Exchange Ratio in accordance with the
    terms of the applicable warrant agreement.

shares of Parent Common Stock (less the number of shares of Parent Common Stock,
if any, to be deposited in the  Escrow Fund on such holder's behalf pursuant  to
Article  VII hereof), plus cash in lieu  of fractional shares in accordance with
Section 1.6, to which such holder is  entitled pursuant to Section 1.6, and  the
Certificate  so surrendered shall forthwith be  canceled. As soon as practicable
after the Effective Time, and subject  to and in accordance with the  provisions
of  Article VII hereof, Parent shall cause to be distributed to the Escrow Agent
(as defined  in Article  VII) a  certificate or  certificates representing  that
number  of shares of Parent Common Stock  equal to the Escrow Amount which shall
be registered in the name of the Escrow Agent. Such shares shall be beneficially
owned by the holders on  whose behalf such shares  were deposited in the  Escrow
Fund  and shall be  available to compensate  Parent as provided  in Article VII.
Until so surrendered, each outstanding Certificate that, prior to the  Effective
Time,  represented shares of Company Capital Stock will be deemed from and after
the   Effective   Time,   for   all   corporate   purposes,   other   than   the

                                      A-7
<PAGE>
payment  of dividends, to evidence the ownership of the number of full shares of
Parent Common Stock into which such  shares of Company Capital Stock shall  have
been  so converted and  the right to  receive an amount  in cash in  lieu of the
issuance of any fractional shares in accordance with Section 1.6.

    (d)  DISTRIBUTIONS  WITH RESPECT  TO UNEXCHANGED  SHARES.   No dividends  or
other  distributions declared or  made after the Effective  Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid  to
the holder of any unsurrendered Certificate with respect to the shares of Parent
Common  Stock represented thereby until the holder of record of such Certificate
shall surrender such Certificate. Subject to applicable law, following surrender
of any  such Certificate,  there  shall be  paid to  the  record holder  of  the
certificates representing whole shares of Parent Common Stock issued in exchange
therefor,  without  interest,  at the  time  of  such surrender,  the  amount of
dividends or other  distributions with a  record date after  the Effective  Time
theretofore paid with respect to such whole shares of Parent Common Stock.

    (e)  TRANSFERS OF OWNERSHIP.  If any certificate for shares of Parent Common
Stock  is  to be  issued in  a name  other  than that  in which  the certificate
surrendered in exchange therefor  is registered, it will  be a condition of  the
issuance  thereof that the certificate so  surrendered will be properly endorsed
and otherwise in proper  form for transfer and  that the person requesting  such
exchange  will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason  of the issuance of  a certificate for shares  of
Parent  Common Stock in any name other than that of the registered holder of the
certificate surrendered, or  established to  the satisfaction of  Parent or  any
agent designated by it that such tax has been paid or is not payable.

    (f)  NO LIABILITY.  Notwithstanding anything to the contrary in this Section
1.8,  none of the Exchange Agent, the  Surviving Corporation or any party hereto
shall be liable to a holder of shares of Parent Common Stock or Company  Capital
Stock  for  any  amount properly  paid  to  a public  official  pursuant  to any
applicable abandoned property, escheat or similar law.

    1.9  NO FURTHER  OWNERSHIP RIGHTS IN  COMPANY COMMON STOCK.   All shares  of
Parent  Common Stock issued upon the surrender for exchange of shares of Company
Capital Stock in accordance  with the terms hereof  (including any cash paid  in
respect thereof) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Capital Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares  of Company Capital Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to  the
Surviving  Corporation for any  reason, they shall be  canceled and exchanged as
provided in this Article I.

    1.10  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any certificates
evidencing shares  of Company  Capital Stock  shall have  been lost,  stolen  or
destroyed,  the Exchange Agent shall issue in  exchange for such lost, stolen or
destroyed certificates, upon  the making  of an affidavit  of that  fact by  the
holder  thereof,  such shares  of Parent  Common Stock  and cash  for fractional
shares, if any, as may be  required pursuant to Section 1.6; provided,  however,
that  Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the  owner of such  lost, stolen or  destroyed certificates  to
deliver  a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent or the Exchange Agent with respect to  the
certificates alleged to have been lost, stolen or destroyed.

    1.11  TAX AND ACCOUNTING CONSEQUENCES.  It is intended by the parties hereto
that  the Merger  shall (i)  constitute a  reorganization within  the meaning of
Section 368 of the Internal  Revenue Code of 1986,  as amended (the "CODE")  and
(ii) qualify for accounting treatment as a pooling of interests.

    1.12  TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after the
Effective  Time, any such further action is  necessary or desirable to carry out
the purposes of this Agreement and  to vest the Surviving Corporation with  full
right,  title  and  possession  to  all  assets,  property,  rights, privileges,

                                      A-8

powers  and franchises of the Company and Merger Sub, the officers and directors
of the  Company  and Merger  Sub  are fully  authorized  in the  name  of  their
respective corporations or otherwise to take, and will take, all such lawful and
necessary action.

    The Company hereby represents and warrants to Parent and Merger Sub, subject
to such exceptions as are clearly disclosed in the disclosure letter supplied by

EFFECT").  The Company has delivered a true  and correct copy of its Certificate
of Incorporation and Bylaws, each as amended to date, to Parent.

    2.2  COMPANY CAPITAL STRUCTURE.

    (a) The  authorized capital  stock  of the  Company consists  of  20,000,000

Stock, of  1,083,334 shares  are  issued and  outstanding, 7,760,000  shares  of
authorized  Series B Preferred  Stock, of which 7,048,505  shares are issued and

shares  of Company  Capital Common  Stock are  duly authorized,  validly issued,
fully paid and non-assessable  and not subject to  preemptive rights created  by
statute,  the  Certificate of  Incorporation  or Bylaws  of  the Company  or any

number of shares of Common Stock subject  to such option, the exercise price  of
such  option  and the  vesting schedule  for such  option, including  the extent
vested to date and whether the exercisability of such option will be accelerated

of shares  of  Common  Stock  into  which  such  Series  B  Preferred  Stock  is
convertible) for issuance upon exercise of outstanding warrants. Schedule 2.2(b)
sets forth for each of the Warrants the name of the holder and exercise price of
such warrants. Except for the Company Options and warrants described in Schedule
2.2(b), there are no options, warrants, calls, rights, commitments or agreements
of  any character, written or oral, to which  the Company is a party or by which
it is  bound obligating  the  Company to  issue,  deliver, sell,  repurchase  or
redeem,  or cause  to be issued,  delivered, sold, repurchased  or redeemed, any
shares of the capital stock of the  Company. Except for the Company Options  and
warrants  described in Schedule  2.2(b), there are  no Options, warrants, calls,
rights, commitments or agreements  of any character, written  or oral, to  which
the  Company is a party or by which it is bound obligating the Company to grant,
extend, accelerate the vesting of, change the price of, otherwise amend or enter
into any such

                                      A-9
<PAGE>
option, warrant, call, right,  commitment or agreement.  The holders of  Company
Options  and warrants have been or will be given, or shall have properly waived,
any required notice prior to the Merger  and all such rights will be  terminated
at or prior to the Effective Time. As a result of the Merger, Parent will be the
record  and sole  beneficial owner  of all Company  Capital Stock  and rights to

this  Agreement by  the Company's  stockholders, the  Company has  all requisite
corporate power and authority to enter into this Agreement and to consummate the
transactions  contemplated   hereby.  The   vote  required   of  the   Company's

Preferred  Stock voting  separately as  a single class  (in each  case with each
share of Preferred Stock being entitled to a number of votes equal to the number

be  converted on the  record date for  the vote). The  execution and delivery of
this Agreement and the consummation of the transactions contemplated hereby have
been duly  authorized by  all necessary  corporate  action on  the part  of  the

by the Company and constitutes the valid and binding obligation of the  Company,
enforceable  in accordance with its terms. Except  as set forth on Schedule 2.4,
subject only to the approval of the  Merger and this Agreement by the  Company's
stockholders,  the execution and delivery of  this Agreement by the Company does
not, and,  as  of the  Effective  Time,  the consummation  of  the  transactions
contemplated  hereby will not, conflict with, or  result in any violation of, or
default under (with or without notice or  lapse of time, or both), or give  rise

loss of any benefit under  (any such event, a  "Conflict") (i) any provision  of
the  Certificate of Incorporation or Bylaws of the Company or (ii) any mortgage,
indenture, lease, contract or other agreement or instrument, permit, concession,

any Conflict), is required by or with respect to the Company in connection  with
the  execution  and  delivery  of  this Agreement  or  the  consummation  of the
transactions contemplated hereby, except for  (i) the filing of the  Certificate
of  Merger with  the Delaware Secretary  of State, (ii)  such consents, waivers,
approvals, orders, authorizations,  registrations, declarations  and filings  as
may  be required  under applicable federal  and state securities  laws and (iii)

sublicense  or  agreement, nor  entitle  any other  party  to any  such license,
sublicense or  agreement to  terminate  or modify  such license,  sublicense  or
agreement.  Except as set forth in Schedules  2.11(a) or 2.11(b), the Company is
the sole and exclusive owner or licensee of, with all right, title and  interest

Intellectual Property Rights,  and has  sole and  exclusive rights  (and is  not
contractually  obligated to pay  any compensation to any  third party in respect
thereof) to the use thereof or  the material covered thereby in connection  with
the  services or products in respect  of which the Company Intellectual Property
Rights are being used.

    (c) No claims with respect to the Company Intellectual Property Rights  have
been  asserted or are, to the Company's knowledge, threatened by any person, nor
are there any valid grounds for any bona fide claims (i) to the effect that  the

infringes on any copyright,  patent, trade mark, service  mark, trade secret  or
other  proprietary right, (ii) against the use by the Company of any trademarks,
service marks,  trade  names,  trade secrets,  copyrights,  maskworks,  patents,
technology,  know-how or computer software programs and applications used in the
Company's business as currently conducted or as proposed to be conducted by  the
Company,  or  (iii)  challenging  the  ownership  by  the  Company,  validity or
effectiveness of any of the Company Intellectual Property Rights. All registered
trademarks, service  marks and  copyrights held  by the  Company are  valid  and
subsisting. The business of the Company as currently conducted or as proposed to
be  conducted by the  Company has not  and does not  infringe on any proprietary
right of  any third  party. To  the Company's  knowledge, there  is no  material
unauthorized  use,  infringement  or  misappropriation  of  any  of  the Company
Intellectual Property  Rights by  any  third party,  including any  employee  or
former  employee  of  the Company.  No  Company Intellectual  Property  Right or
product of the Company or any of its subsidiaries is subject to any  outstanding

business of Parent.

    3.6   LITIGATION.  There is  no action, suit, proceeding, claim, arbitration
or investigation  pending, or  as to  which Parent  has received  any notice  of
assertion  against Parent  which in any  manner challenges or  seeks to prevent,
enjoin, alter or materially delay any  of the transactions contemplated by  this
Agreement.

                                      A-22
<PAGE>
by way of merger, purchase of capital stock, purchase of assets or otherwise) or

    5.1  REGISTRATION STATEMENT; STOCKHOLDER MEETINGS.

    (i) As promptly as practicable after the execution of this Agreement, Parent
shall  prepare,  and  the  Company shall  assist  in  preparing,  a registration
statement on Form S-4 (the "Registration Statement") pertaining to the offer and
sale of shares of Parent Common Stock to be issued by virtue of the Merger.  The
Registration  Statement  shall include  therein  a Proxy  Statement  (the "PROXY
STATEMENT") relating to the solicitation of  the consent of the stockholders  of
the  Company to  the Merger.  Parent shall  file with  the SEC  the Registration
Statement as soon  as is reasonably  practicable following preparation  thereof.
The  Company shall provide to Parent and  its counsel for inclusion in the Proxy
Statement, in  form and  substance  reasonably satisfactory  to Parent  and  its
counsel,    such   information   concerning   the   Company,   its   operations,
capitalization, technology, share ownership and other material as Parent or  its
counsel  may reasonably request.  Each of Parent  and the Company  shall use its
reasonable efforts  to  respond  to  any  comments  of  the  SEC,  to  have  the
Registration  Statement declared effective under the Securities Act of 1933 (the
"SECURITIES ACT") as promptly as practicable after such filing and to cause  the
Proxy  Statement  to be  mailed to  the Company's  stockholders at  the earliest
practicable time. Each party  will notify the other  parties hereto promptly  of
the  receipt of any comments from the SEC or its staff and of any request by the
SEC or its staff for amendments or supplements to the Registration Statement  or
the  Proxy Statement  or for  additional information  and will  supply the other
party with  copies  of all  correspondence  between such  party  or any  of  its
representatives,  on the one hand, and the SEC, or its staff, on the other hand,
with respect to the Registration Statement or the Proxy Statement. Whenever  any
event occurs which should be set forth

                                      A-23
<PAGE>
in  an  amendment or  supplement  to the  Proxy  Statement and  the Registration
Statement, Parent or the Company, as the case may be, shall promptly inform  the
other  company of such  occurrence and cooperate  in filing with  the SEC or its
staff.

    (ii) As promptly as practicable after the execution of this Agreement and at
such time as Parent may request so as not to interfere with the S-4 registration
process,  the  Company  shall  submit   this  Agreement  and  the   transactions
contemplated hereby to its stockholders for approval and adoption as provided by
applicable law. The Company shall use its best efforts to solicit and obtain the
consent  of its stockholders sufficient to approve the Merger and this Agreement
and to enable  the Closing to  occur as promptly  as practicable. The  materials
submitted  to the Company's stockholders shall be subject to review and approval
by Parent and include information regarding the Company, the terms of the Merger
and this Agreement and the unanimous recommendation of the Board of Directors of
the Company in favor of the Merger and this Agreement.

    5.2    ACCESS  TO  INFORMATION.    Subject  to  any  applicable  contractual
confidentiality  obligations (which  the Company shall  use its  best efforts to
cause to be  waived) each  party shall afford  the others  and its  accountants,
counsel  and  other representatives,  reasonable  access during  normal business
hours during  the  period  prior  to  the Effective  Time  to  (a)  all  of  its
properties,  books,  contracts,  agreements  and  records,  and  (b)  all  other
information concerning  the  business,  properties  and  personnel  (subject  to
restrictions  imposed  by applicable  law) of  it as  the others  may reasonably
request. No information or knowledge  obtained in any investigation pursuant  to
this  Section 5.2  shall affect  or be  deemed to  modify any  representation or
warranty contained herein or the conditions to the obligations of the parties to
consummate the Merger.

    5.3   CONFIDENTIALITY.   Each of  the parties  hereto hereby  agrees to  and
reaffirms the terms and provisions of the Mutual Nondisclosure Agreement between
Parent and the Company dated as of December 9, 1995.

    5.4   EXPENSES.   Whether  or not  the Merger  is consummated,  all fees and
expenses incurred in connection with  the Merger including, without  limitation,
all  legal, accounting,  financial advisory, consulting  and all  other fees and
expenses of  third parties  ("THIRD  PARTY EXPENSES")  incurred  by a  party  in
connection  with the negotiation and effectuation of the terms and conditions of
this Agreement and the transactions contemplated hereby, shall be the obligation
of the respective  party incurring  such fees and  expenses; provided,  however,
that  Parent and the  Company shall share  equally all fees  and expenses, other
than attorneys, accountants and financial advisors fees, incurred in  connection
with  the printing and filing of the Registration Statement (including financial
statements and exhibits) and any amendments or supplements thereto.

    5.5   PUBLIC  DISCLOSURE.   Unless  otherwise required  by  law  (including,
without  limitation,  securities  laws)  or,  as to  Parent,  by  the  rules and
regulations of the National  Association of Securities  Dealers, Inc., prior  to
the  Effective Time, no disclosure (whether or not in response to an inquiry) of
the subject matter of this  Agreement shall be made  by any party hereto  unless
approved by Parent and the Company prior to release, provided that such approval
shall not be unreasonably withheld.

    5.6   CONSENTS.  The Company shall  use its reasonable efforts to obtain the
consents, waivers and approvals under any of the Contracts as may be required in
connection with the Merger (all of such consents, waivers and approvals are  set
forth in Company Schedules) so as to preserve all rights of, and benefits to the
Company thereunder.

    5.7   FIRPTA COMPLIANCE.  On the  Closing Date, the Company shall deliver to

    5.8  REASONABLE EFFORTS.   Subject to the  terms and conditions provided  in
this  Agreement, each of the parties hereto  shall use its reasonable efforts to
take promptly, or cause to be taken,  all actions, and to do promptly, or  cause
to  be done, all things necessary, proper or advisable under applicable laws and
regulations to  consummate  and  make effective  the  transactions  contemplated
hereby to obtain all

                                      A-24
<PAGE>
necessary   waivers,  consents  and  approvals   and  to  effect  all  necessary
registrations and filings and to remove any injunctions or other impediments  or
delays,  legal  or otherwise,  in  order to  consummate  and make  effective the
transactions contemplated by this Agreement for  the purpose of securing to  the
parties hereto the benefits contemplated by this Agreement; provided that Parent
shall  not be required to  agree to any divestiture by  Parent or the Company or
any of Parent's subsidiaries or affiliates of shares of capital stock or of  any
business,  assets or property of Parent or its subsidiaries or affiliates or the
Company or its affiliates, or the  imposition of any material limitation on  the
ability of any of them to conduct their businesses or to own or exercise control
of such assets, properties and stock.

    5.9   NOTIFICATION OF CERTAIN MATTERS.  The Company shall give prompt notice
to Parent,  and Parent  shall give  prompt notice  to the  Company, of  (i)  the
occurrence  or non-occurrence of any event,  the occurrence or non-occurrence of
which is  likely to  cause any  representation or  warranty of  the Company  and
Parent  or Merger Sub, respectively, contained in this Agreement to be untrue or
inaccurate in any material respect at or  prior to the Effective Time except  as
contemplated  by their Agreement (including the  Company Schedules) and (ii) any
failure of the Company or Parent, as the case may be, to comply with or  satisfy
in any material respect any covenant, condition or agreement to be complied with
or satisfied by it hereunder; provided, however, that the delivery of any notice
pursuant  to this Section 5.9  shall not limit or  otherwise affect any remedies
available to the party receiving such notice.

    5.10   POOLING  ACCOUNTING.   Parent  and the  Company  shall each  use  its
reasonable  efforts  to cause  the business  combination to  be effected  by the
Merger to be accounted  for as a  pooling of interests. Each  of Parent and  the
Company  shall use  its reasonable  efforts to  cause its  respective employees,
directors, stockholders  and  affiliates  not  to take  any  action  that  would
adversely  affect the ability of Parent  to account for the business combination
to be effected by the Merger as  a pooling of interests. Neither Parent nor  the
Company  shall take  any action,  including the  acceleration of  vesting of any
options, warrants, restricted  stock or other  rights to acquire  shares of  the
capital  stock  of  the  Company,  which reasonably  would  be  expected  to (i)
interfere with  Parent's ability  to account  for  the Merger  as a  pooling  of
interests   or  (ii)  jeopardize  the  tax-free  nature  of  the  reorganization
hereunder.

    5.11  AFFILIATE AGREEMENTS.  Schedule 5.12 sets forth those persons who,  in
the  Company's reasonable judgment,  are "affiliates" of  the Company within the
meaning of Rule  145 (each  such person  an "Affiliate")  promulgated under  the
Securities  Act ("Rule 145"). The Company  shall provide Parent such information
and documents as Parent shall reasonably request for purposes of reviewing  such
list.  Each  of  Parent and  the  Company has  delivered  or shall  cause  to be
delivered to the other, concurrently with the execution of this Agreement,  from
each of their respective Affiliates, an executed Affiliate Agreement in the form
attached  hereto  as EXHIBIT  A or  EXHIBIT B.  Parent and  Merger Sub  shall be
entitled to place appropriate legends on the certificates evidencing any  Parent
Common  Stock to be received by Affiliates  of the Company pursuant to the terms
of this Agreement, and  to issue appropriate stop  transfer instructions to  the
transfer  agent  for Parent  Common  Stock, consistent  with  the terms  of such
Affiliate Agreements.

    5.12  ADDITIONAL DOCUMENTS  AND FURTHER ASSURANCES.   Each party hereto,  at
the  request of  the other  party hereto, shall  execute and  deliver such other
instruments and do and perform such other acts and things as may be necessary or
desirable for effecting completely  the consummation of  this Agreement and  the
transactions contemplated hereby.

EXHIBIT C (the "VOTING  AGREEMENTS"), agreeing, among other  things, to vote  in
favor of the Merger and against any competing proposals.

    5.16   BLUE SKY LAWS.   Parent shall take such steps  as may be necessary to
comply with the  securities and  blue sky laws  of all  jurisdictions which  are
applicable  to  the issuance  of the  Parent Common  Stock pursuant  hereto. The
Company shall use  its best  efforts to  assist Parent  as may  be necessary  to
comply  with the  securities and  blue sky laws  of all  jurisdictions which are
applicable in  connection with  the  issuance of  Parent Common  Stock  pursuant
hereto.

    5.17    INDEMNIFICATION.   Parent  shall  either  (i) cause  the  Company to
continue to indemnify or (ii) directly  indemnify the persons who are  currently
officers  and  directors of  the Company  substantially  in accordance  with the
Bylaws of the Company as they are currently in effect for action or inaction  by
such person prior to the Merger.

    5.18   PARENT REGISTRATIONS.  Parent  will not file a registration statement
with the SEC covering  the issuance of  any new shares of  the capital stock  of
Parent  until Parent has publicly announced  financial results covering a period
of combined operations of Parent and the  Company of at least thirty (30)  days,
provided,  however,  that  the  foregoing restriction  shall  not  apply  to (i)
registrations  covering  any  employee  benefit  plans,  (ii)  the  Registration
Statement  as contemplated herein, and (iii) any registrations which the Company
is required  to  file  pursuant  to any  demand  registration  rights  or  other
contractual  rights, and  provided further  that with  respect to  such required
registrations, Parent shall  be permitted  to include in  any such  registration
statement  enough primary  issue shares  to cover  the expenses  of the required
registration and to  allow the registration  expenses to be  capitalized on  its
balance sheet rather than expensed on its profit and loss statement.

                                  ARTICLE VII
               SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW

    7.1    SURVIVAL OF  REPRESENTATIONS AND  WARRANTIES.   All of  the Company's
representations and warranties in this Agreement or in any instrument  delivered
pursuant  to this  Agreement (each as  modified by the  Company Schedules) shall
survive the Merger and continue until 5:00 p.m., California time, on the earlier
of the date which  is the date of  the auditor's report for  the first audit  of
Parent's  financial statements after the  Closing Date or the  date which is one
year following the Closing Date (the "Expiration Date").

    7.2  ESCROW ARRANGEMENTS.

    (a)  ESCROW FUND.  At the Effective Time the Company's stockholders will  be
deemed  to have received and deposited with  the Escrow Agent (as defined below)
the Escrow Amount (plus any  additional shares as may  be issued upon any  stock
split, stock dividend or recapitalization effected by Parent after the Effective
Time)  without any  act of  any stockholder.  As soon  as practicable  after the
Effective Time, the Escrow Amount, without  any act of any stockholder, will  be
deposited  with  First Trust  of California  National Association  Global Escrow
D.S., (or other institution  acceptable to Parent  and the Securityholder  Agent
(as defined in Section 7.2(g) below)) as Escrow Agent (the "ESCROW AGENT"), such
deposit  to constitute an escrow fund (the  "ESCROW FUND") to be governed by the
terms set forth  herein and at  Parent's cost  and expense. The  portion of  the
Escrow  Amount contributed on behalf of each stockholder of the Company shall be
in proportion  to the  aggregate Parent  Common Stock  which such  holder  would
otherwise  be entitled  under Section  1.6(a). No  portion of  the Escrow Amount
shall be contributed in respect of  any Company Options or warrants. The  Escrow
Fund  shall be available to compensate Parent and its affiliates for any claims,
losses,  liabilities,  damages,  deficiencies,  costs  and  expenses,  including
reasonable  attorneys'  fees and  expenses,  and expenses  of  investigation and
defense (hereinafter individually a  "LOSS" and collectively "LOSSES")  incurred
by  Parent,  its officers,  directors,  or affiliates  (including  the Surviving
Corporation) directly or indirectly as a result of any inaccuracy or breach of a
representation or warranty of the Company or any contained in Article II  herein
(as modified by the Company Schedules), or any failure by the Company to perform
or  comply  with any  covenant  contained herein.  Parent  and the  Company each
acknowledge that such Losses, if  any, would relate to unresolved  contingencies
existing  at the Effective Time,  which if resolved at  the Effective Time would
have led  to a  reduction  in the  aggregate  Merger consideration.  Subject  to
Section  8.3 below, nothing herein shall limit  the liability of the Company for
any breach of any  representation, warranty or covenant  if the Merger does  not
close.  Parent may not receive any shares  from the Escrow Fund unless and until
Officer's Certificates (as defined in  paragraph (d) below) identifying  Losses,
the aggregate amount of which exceed $500,000, have been delivered to the Escrow
Agent  as provided in paragraph  (e); in such case,  Parent may recover from the
Escrow Fund its Losses in excess of the first $500,000.

    (b)      ESCROW   PERIOD;   DISTRIBUTION   UPON   TERMINATION   OF    ESCROW
PERIODS.   Subject to  the following requirements,  the Escrow Fund  shall be in
existence immediately following the Effective  Time and shall terminate at  5:00
p.m.,  California time, on  the Expiration Date  (the "ESCROW PERIOD"); provided
that the Escrow Period shall not terminate with respect to such amount (or  some
portion  thereof),  that together  with the  aggregate  amount remaining  in the
Escrow Fund is necessary  in the reasonable judgment  of Parent, subject to  the
objection  of the  Securityholder Agent  and the  subsequent arbitration  of the
matter in  the  manner  provided  in  Section  7.2(f)  hereof,  to  satisfy  any
unsatisfied  claims  concerning facts  and circumstances  existing prior  to the
termination of  such  Escrow  Period  specified  in  any  Officer's  Certificate
delivered  to the Escrow  Agent prior to  termination of such  Escrow Period. As
soon as all such claims  have been resolved, the  Escrow Agent shall deliver  to
the stockholders of the Company the remaining portion of the Escrow Fund and not
required   to  satisfy  such  claims.  Deliveries   of  Escrow  Amounts  to  the
stockholders of the  Company pursuant to  this Section 7.2(b)  shall be made  in
proportion to their respective original contributions to the Escrow Fund.

                                      A-29
<PAGE>
    (c)  PROTECTION OF ESCROW FUND.

    (i)  The Escrow Agent  shall hold and  safeguard the Escrow  Fund during the
Escrow Period, shall  treat such fund  as a  trust fund in  accordance with  the
terms  of this Agreement  and not as the  property of Parent  and shall hold and
dispose of the Escrow Fund only in accordance with the terms hereof.

    (ii) Any shares of Parent Common Stock or other equity securities issued  or
distributed  by  Parent  (including  shares issued  upon  a  stock  split) ("NEW
SHARES") in respect of  Parent Common Stock  in the Escrow  Fund which have  not
been  released from the Escrow Fund shall be added to the Escrow Fund and become
a part thereof. New Shares  issued in respect of  shares of Parent Common  Stock
which  have been released from the Escrow Fund  shall not be added to the Escrow
Fund but shall be  distributed to the recordholders  thereof. Cash dividends  on
Parent  Common  Stock  shall  not be  added  to  the Escrow  Fund  but  shall be
distributed to the recordholders thereof.

   (iii) Each stockholder shall have voting rights with respect to the shares of
Parent Common Stock contributed to the  Escrow Fund by such stockholder (and  on
any  voting securities  added to the  Escrow Fund  in respect of  such shares of
Parent Common Stock).

    (d)  CLAIMS UPON ESCROW FUND.

    (i) Upon receipt by the Escrow Agent at  any time on or before the last  day
of  the  Escrow Period  of a  certificate signed  by any  officer of  Parent (an
"OFFICER'S CERTIFICATE"): (A) stating that  Parent has paid or properly  accrued
or  reasonably anticipates that  it will have  to pay or  accrue Losses, and (B)
specifying in reasonable detail the individual  items of Losses included in  the
amount  so stated, the date each such item  was paid or properly accrued, or the
basis for such anticipated liability,  and the nature of the  misrepresentation,
breach  of warranty or covenant to which  such item is related, the Escrow Agent
shall, subject to the provisions of Section 7.2(e) hereof, deliver to Parent out
of the Escrow Fund,  as promptly as practicable,  shares of Parent Common  Stock
held in the Escrow Fund in an amount equal to such Losses.

    (ii)  For the purposes of determining the  number of shares of Parent Common
Stock to be  delivered to  Parent out  of the  Escrow Fund  pursuant to  Section
7.2(d)(i)  hereof, the  shares of  Parent Common  Stock shall  be valued  at the
average of  the  closing  prices  of Parent's  Common  Stock  on  the  principal
securities  exchange on which Parent's Common Stock is then traded, or if not so
traded, the National  Market System  of the National  Association of  Securities
Dealers  Automated  Quotation system,  in either  case as  reported in  THE WALL
STREET JOURNAL for the five (5) consecutive trading days ending on the date that
is two (2) trading days prior to the Closing Date. Parent and the Securityholder
Agent shall  certify such  fair market  value in  a certificate  signed by  both
Parent  and the Securityholder Agent, and  shall deliver such certificate to the
Escrow Agent.

    (e)   OBJECTIONS TO  CLAIMS.   At  the time  of  delivery of  any  Officer's
Certificate  to the Escrow Agent, a duplicate  copy of such certificate shall be
delivered to the Securityholder Agent and for a period of thirty (30) days after
such delivery, the Escrow Agent shall make  no delivery to Parent of any  Escrow
Amounts  pursuant to  Section 7.2(d) hereof  unless the Escrow  Agent shall have
received written authorization from the Agent  to make such delivery. After  the
expiration  of such thirty (30) day period, the Escrow Agent shall make delivery
of shares of Parent Common Stock from the Escrow Fund in accordance with Section
7.2(d) hereof, provided  that no such  payment or  delivery may be  made if  the
Securityholder  Agent shall object in  a written statement to  the claim made in
the Officer's Certificate, and such statement  shall have been delivered to  the
Escrow Agent prior to the expiration of such thirty (30) day period.

    (f)  RESOLUTION OF CONFLICTS; ARBITRATION.

    (i) In case the Securityholder Agent shall so object in writing to any claim
or claims made in any Officer's Certificate, the Securityholder Agent and Parent
shall  attempt in good faith to agree  upon the rights of the respective parties
with respect to  each of  such claims. If  the Securityholder  Agent and  Parent
should so agree, a memorandum setting forth such agreement shall be prepared and
signed by

                                      A-30
<PAGE>
both  parties and shall be furnished to the Escrow Agent. The Escrow Agent shall
be entitled  to rely  on any  such memorandum  and distribute  shares of  Parent
Common Stock from the Escrow Fund in accordance with the terms thereof.

    (ii)  If  no such  agreement can  be reached  after good  faith negotiation,
either Parent or the Securityholder Agent  may demand arbitration of the  matter
unless the amount of the damage or loss is at issue in pending litigation with a
third party, in which event arbitration shall not be commenced until such amount
is  ascertained or both parties  agree to arbitration; and  in either such event
the matter  shall be  settled  by arbitration  conducted by  three  arbitrators.
Parent  and the Securityholder  Agent shall each select  one arbitrator, and the
two arbitrators  so selected  shall select  a third  arbitrator, each  of  which
arbitrators   shall  be  independent  and  have  at  least  ten  years  relevant
experience. The  arbitrators  shall set  a  limited time  period  and  establish
procedures designed to reduce the cost and time for discovery while allowing the
parties  an opportunity,  adequate in the  sole judgment of  the arbitrators, to
discover relevant information from the opposing parties about the subject matter
of the  dispute. The  arbitrators shall  rule upon  motions to  compel or  limit
discovery  and shall have the authority to impose sanctions, including attorneys
fees and costs, to the extent as a court of competent law or equity, should  the
arbitrators   determine   that   discovery   was   sought   without  substantial
justification or that discovery was  refused or objected to without  substantial
justification.  The decision of  a majority of  the three arbitrators  as to the
validity and amount of any claim in such Officer's Certificate shall be  binding
and  conclusive upon the parties to this Agreement, and notwithstanding anything
in Section  7.2(e)  hereof,  the  Escrow  Agent shall  be  entitled  to  act  in
accordance  with such decision and  make or withhold payments  out of the Escrow
Fund in  accordance therewith.  Such  decision shall  be  written and  shall  be
supported  by written findings of fact and conclusions which shall set forth the
award, judgment, decree or order awarded by the arbitrators.

   (iii) Judgment upon any award rendered  by the arbitrators may be entered  in
any  court having jurisdiction. Any such arbitration  shall be held in San Mateo
or Santa  Clara Counties,  California under  the  rules then  in effect  of  the
Judicial  Arbitration and Mediation Services, Inc.  For purposes of this Section
7.2(f), in any arbitration  hereunder in which any  claim or the amount  thereof
stated  in the Officer's Certificate  is at issue, Parent  shall be deemed to be
the Non-Prevailing Party  in the event  that the arbitrators  award Parent  less
than  the sum of one-half  (1/2) of the disputed amount  plus any amounts not in
dispute; otherwise,  the  stockholders of  the  Company as  represented  by  the
Securityholder  Agent  shall  be  deemed to  be  the  Non-Prevailing  Party. The
Non-Prevailing Party to an arbitration shall  pay its own expenses, the fees  of
each  arbitrator, the administrative costs of the arbitration, and the expenses,
including without limitation, reasonable attorneys' fees and costs, incurred  by
the other party to the arbitration.

    (g)  SECURITYHOLDER AGENT OF THE STOCKHOLDERS; POWER OF ATTORNEY.

    (i)  In the event that the Merger is approved, effective upon such vote, and
without further act of any stockholder, Gary J. Morgenthaler shall be  appointed
as  agent and attorney-in-fact (the "SECURITYHOLDER AGENT") for each stockholder
of the Company (except such stockholders, if any, as shall have perfected  their
appraisal  or dissenters' rights under Delaware  Law or California Law), for and
on behalf  of stockholders  of the  Company,  to give  and receive  notices  and
communications, to authorize delivery to Parent of shares of Parent Common Stock
from  the Escrow  Fund in satisfaction  of claims  by Parent, to  object to such
deliveries, to agree to, negotiate,  enter into settlements and compromises  of,
and  demand  arbitration  and  comply  with  orders  of  courts  and  awards  of
arbitrators with respect to  such claims, and to  take all actions necessary  or
appropriate  in the judgment  of Securityholder Agent  for the accomplishment of
the foregoing. Such  agency may be  changed by the  stockholders of the  Company
from  time to time upon  not less than thirty (30)  days prior written notice to
Parent; provided that the Securityholder Agent may not be removed unless holders
of a two-thirds interest  of the Escrow  Fund agree to such  removal and to  the
identity of the substituted agent. Any vacancy in the position of Securityholder
Agent  may be  filled by approval  of the holders  of a majority  in interest of

                                      A-31
<PAGE>
the Escrow Fund. No bond shall be required of the Securityholder Agent, and  the
Securityholder  Agent shall  not receive compensation  for his  or her services.
Notices or communications to or  from the Securityholder Agent shall  constitute
notice to or from each of the stockholders of the Company.

    (ii)  The  Securityholder Agent  shall not  be  liable for  any act  done or
omitted hereunder as Securityholder Agent while acting in good faith and in  the
exercise of reasonable judgment. The stockholders of the Company on whose behalf
the  Escrow Amount was contributed to  the Escrow Fund shall severally indemnify
the Securityholder Agent and hold the Securityholder Agent harmless against  any
loss,  liability or expense incurred without negligence or bad faith on the part
of the  Securityholder  Agent and  arising  out of  or  in connection  with  the
acceptance  or administration  of the  Securityholder Agent's  duties hereunder,
including the reasonable fees and expenses of any legal counsel retained by  the
Securityholder Agent.

    (h)   ACTIONS  OF THE  SECURITYHOLDER AGENT.   A  decision, act,  consent or
instruction of the Securityholder Agent shall  constitute a decision of all  the
stockholders  for whom a portion of the Escrow Amount otherwise issuable to them
are deposited in the Escrow Fund and shall be final, binding and conclusive upon
each of such stockholders,  and the Escrow  Agent and Parent  may rely upon  any
such  decision, act, consent or instruction of the Securityholder Agent as being
the decision, act, consent or instruction of each every such stockholder of  the
Company.  The Escrow Agent and Parent are  hereby relieved from any liability to
any person for  any acts done  by them  in accordance with  such decision,  act,
consent or instruction of the Securityholder Agent.

    (i)  THIRD-PARTY CLAIMS.  In the event Parent becomes aware of a third-party
claim  which Parent  believes may  result in a  demand against  the Escrow Fund,
Parent  shall  notify  the   Securityholder  Agent  of   such  claim,  and   the
Securityholder  Agent, as  representative for  the stockholders  of the Company,
shall be  entitled, at  their expense,  to participate  in any  defense of  such
claim.  Parent shall have  the right in  its sole discretion  to settle any such
claim; provided, however,  that except  with the consent  of the  Securityholder
Agent, no settlement of any such claim with third-party claimants shall alone be
determinative  of the amount of any claim  against the Escrow Fund. In the event
that  the  Securityholder  Agent  has  consented  to  any  such  settlement  and
acknowledged  that  the claim  is a  valid  claim against  the Escrow  Fund, the
Securityholder Agent  shall have  no  power or  authority  to object  under  any
provision  of this Article VII to the amount  of any claim by Parent against the
Escrow Fund with respect to such settlement.

    (j)  ESCROW AGENT'S DUTIES.

    (i) The Escrow  Agent shall be  obligated only for  the performance of  such
duties  as are specifically set forth herein, and as set forth in any additional
written escrow instructions which the Escrow Agent may receive after the date of
this Agreement which are signed by  an officer of Parent and the  Securityholder
Agent,  and may rely and shall be protected in relying or refraining from acting
on any instrument reasonably believed to be  genuine and to have been signed  or
presented  by the proper party or parties.  The Escrow Agent shall not be liable
for any act done or omitted hereunder as Escrow Agent while acting in good faith
and in the exercise of reasonable judgment, and any act done or omitted pursuant
to the advice of counsel shall be conclusive evidence of such good faith.

    (ii) The Escrow Agent  is hereby expressly authorized  to disregard any  and
all  warnings  given  by any  of  the parties  hereto  or by  any  other person,
excepting only  orders or  process of  courts of  law, and  is hereby  expressly
authorized to comply with and obey orders, judgments or decrees of any court. In
case  the Escrow Agent obeys or complies with any such order, judgment or decree
of any court, the Escrow Agent shall not be liable to any of the parties  hereto
or  to any other person  by reason of such  compliance, notwithstanding any such
order, judgment or decree being  subsequently reversed, modified, annulled,  set
aside, vacated or found to have been entered without jurisdiction.

   (iii)  The Escrow Agent shall not be liable  in any respect on account of the
identity, authority  or  rights  of  the  parties  executing  or  delivering  or
purporting  to  execute or  deliver this  Agreement or  any documents  or papers
deposited or called for hereunder.

                                      A-32
<PAGE>
   (iv) The Escrow Agent shall  not be liable for  the expiration of any  rights
under any statute of limitations with respect to this Agreement or any documents
deposited with the Escrow Agent.

    (v) In performing any duties under the Agreement, the Escrow Agent shall not
be  liable  to any  party for  damages,  losses, or  expenses, except  for gross
negligence or willful  misconduct on the  part of the  Escrow Agent. The  Escrow
Agent  shall not incur any such liability for (A) any act or failure to act made
or omitted in good faith,  or (B) any action taken  or omitted in reliance  upon
any  instrument, including  any written statement  of affidavit  provided for in
this Agreement that the Escrow Agent shall in good faith believe to be  genuine,
nor  will  the  Escrow Agent  be  liable  or responsible  for  forgeries, fraud,
impersonations, or determining  the scope  of any  representative authority.  In
addition, the Escrow Agent may consult with the legal counsel in connection with
Escrow  Agent's duties under this Agreement and  shall be fully protected in any
act taken, suffered, or  permitted by him/her in  good faith in accordance  with
the  advice of counsel. The Escrow Agent  is not responsible for determining and
verifying the authority of any person acting  or purporting to act on behalf  of
any party to this Agreement.

   (vi) If any controversy arises between the parties to this Agreement, or with
any  other party, concerning the subject matter  of this Agreement, its terms or
conditions, the Escrow Agent will not  be required to determine the  controversy
or  to take any action regarding it. The Escrow Agent may hold all documents and
shares of  Parent  Common  Stock  and  may  wait  for  settlement  of  any  such
controversy  by final  appropriate legal proceedings  or other means  as, in the
Escrow Agent's discretion, the Escrow Agent may be required, despite what may be
set forth elsewhere in this Agreement. In such event, the Escrow Agent will  not
be liable for damage.

    Furthermore,  the  Escrow  Agent  may  at  its  option,  file  an  action of
interpleader requiring the parties to answer and litigate any claims and  rights
among  themselves. The Escrow Agent  is authorized to deposit  with the clerk of
the court all documents and shares of Parent Common Stock held in escrow, except
all cost, expenses, charges and reasonable attorney fees incurred by the  Escrow
Agent due to the interpleader action and which the parties jointly and severally
agree  to pay.  Upon initiating  such action,  the Escrow  Agent shall  be fully
released and discharged of and from all obligations and liability imposed by the
terms of this Agreement.

   (vii) The parties and their  respective successors and assigns agree  jointly
and  severally to indemnify and  hold Escrow Agent harmless  against any and all
losses, claims, damages, liabilities,  and expenses, including reasonable  costs
of  investigation, counsel fees, and disbursements that may be imposed on Escrow
Agent or incurred by Escrow Agent in connection with the performance of  his/her
duties under this Agreement, including but not limited to any litigation arising
from this Agreement or involving its subject matter.

  (viii)  The Escrow Agent  may resign at  any time upon  giving at least thirty
(30) days  written  notice to  the  parties;  provided, however,  that  no  such
resignation  shall become effective until the  appointment of a successor escrow
agent which shall be accomplished as  follows: the parties shall use their  best
efforts  to mutually agree on  a successor escrow agent  within thirty (30) days
after receiving  such notice.  If the  parties fail  to agree  upon a  successor
escrow  agent within such time, the Escrow Agent shall have the right to appoint
a successor escrow agent authorized to  do business in the state of  California.
The  successor escrow  agent shall execute  and deliver  an instrument accepting
such appointment and  it shall,  without further acts,  be vested  with all  the
estates,  properties, rights, powers, and duties of the predecessor escrow agent
as if originally  named as escrow  agent. The Escrow  Agent shall be  discharged
from any further duties and liability under this Agreement.

    (k)   FEES.   All  fees of the  Escrow Agent  for performance  of its duties
hereunder shall be  paid by Parent.  It is  understood that the  fees and  usual
charges  agreed  upon  for services  of  the  Escrow Agent  shall  be considered
compensation for ordinary  services as  contemplated by this  Agreement. In  the
event  that the conditions of  this Agreement are not  promptly fulfilled, or if
the Escrow Agent renders any service not  provided for in this Agreement, or  if
the  parties  request  a  substantial  modification  of  its  terms,  or  if any
controversy arises, or if the Escrow Agent is made a party to, or intervenes in,
any

                                      A-33
<PAGE>
litigation pertaining to  this escrow or  its subject matter,  the Escrow  Agent
shall  be reasonably compensated for  such extraordinary services and reimbursed
for all costs, attorney's fees, and expenses occasioned by such default,  delay,
controversy or litigation. Parent promises to pay these sums upon demand.

                                  ARTICLE VIII
                       TERMINATION, AMENDMENT AND WAIVER

    8.1   TERMINATION.  Except as provided  in Section 8.2 below, this Agreement
may be terminated and the  Merger abandoned at any  time prior to the  Effective
Time:

        (a) by mutual consent of the Company and Parent;

        (b) by Parent or the Company if: (i) the Effective Time has not occurred
    by  May 15, 1996 (provided that the  right to terminate this Agreement under
    this clause 8.1(b)(i)  shall not  be available  to any  party whose  willful
    failure  to  fulfill any  obligation  hereunder has  been  the cause  of, or
    resulted in, the failure of  the Effective Time to  occur on or before  such
    date); (ii) there shall be a final nonappealable order of a federal or state
    court  in effect preventing consummation of the Merger; or (iii) there shall
    be any statute, rule, regulation or order enacted, promulgated or issued  or
    deemed  applicable to the Merger by  any governmental entity that would make
    consummation of the Merger illegal;

        (c) by Parent if there shall be any action taken, or any statute,  rule,
    regulation  or order enacted, promulgated or  issued or deemed applicable to
    the Merger, by any Governmental  Entity, which would: (i) prohibit  Parent's
    or  the Company's ownership or  operation of any portion  of the business of
    the Company or  (ii) compel  Parent or  the Company  to dispose  of or  hold
    separate,  as a result of the Merger,  any portion of the business or assets
    of the Company or Parent; in either case, the unavailability of which assets
    or business  would  have  a  Material Adverse  Effect  on  Parent  or  would
    reasonably be expected to have a Material Adverse Effect on Parent's ability
    to realize the benefits expected from the Merger.

        (d)  by Parent if it is not  in material breach of its obligations under
    this Agreement and there has been a breach of any representation,  warranty,
    covenant or agreement contained in this Agreement on the part of the Company
    and as a result of such breach the conditions set forth in Section 6.3(a) or
    6.3(b),  as the case may be, would not then be satisfied; provided, however,
    that if  such breach  is curable  by  the Company  within thirty  (30)  days
    through the exercise of its reasonable best efforts, then for so long as the
    Company  continues to exercise  such reasonable best  efforts Parent may not
    terminate this Agreement under this Section 8.1(d) unless such breach is not
    cured within thirty (30) days  (but no cure period  shall be required for  a
    breach which by its nature cannot be cured);

        (e)  by the Company if  it is not in  material breach of its obligations
    under this Agreement  and there  has been  a breach  of any  representation,
    warranty,  covenant or agreement contained in  this Agreement on the part of
    Parent or Merger Sub and as a result of such breach the conditions set forth
    in Section  6.2(a)  or  6.2(b), as  the  case  may be,  would  not  then  be
    satisfied;  provided, however, that  if such breach is  curable by Parent or
    Merger Sub within thirty  (30) days through the  exercise of its  reasonable
    best efforts, then for so long as Parent or Merger Sub continues to exercise
    such  reasonable best efforts  the Company may  not terminate this Agreement
    under this Section 8.1(e) unless such breach is not cured within thirty (30)
    days (but no cure period shall be required for a breach which by its  nature
    cannot be cured).

        Where  action  is taken  to terminate  this  Agreement pursuant  to this
    Section 8.1, it shall be sufficient for such action to be authorized by  the
    Board of Directors (as applicable) of the party taking such action.

                                      A-34

    8.2   EFFECT OF TERMINATION.  In  the event of termination of this Agreement
as provided in  Section 8.1,  this Agreement  shall forthwith  become void  and,
except as set forth in Section 8.3, there shall be no liability or obligation on
the  part of Parent,  Merger Sub or  the Company, or  their respective officers,
directors or stockholders, provided that each party shall remain liable for  any
breaches  of this Agreement prior  to its termination to  the extent provided in
Section 8.3; and provided further that,  the provisions of Sections 5.3 and  5.4
and  Article VIII of  this Agreement shall  remain in full  force and effect and
survive any termination of this Agreement.

    8.3  BREAKUP FEE.

    (a) In the  event that this  Agreement is terminated  by Parent pursuant  to
Section  8.1(d) hereof, other than as a result of a knowing or willful breach by
the Company of any representation, warranty, covenant or agreement contained  in
this  Agreement  on the  part of  the  Company, then,  within two  business days
following such termination by  Parent, the Company shall  pay to Parent by  wire
transfer  of immediately  available funds the  sum of $12  million as liquidated
damages for the  breach giving rise  to such termination.  Nothing herein  shall
limit  the liability of the  Company for any knowing  or willful breaches of any
representation, warranty, covenant or agreement  contained in this Agreement  on
the part of the Company.

    (b)  In the event that this Agreement  is terminated by the Company pursuant
to Section 8.1(e) hereof, other than as a result of a knowing or willful  breach
by  Parent of any  representation, warranty, covenant  or agreement contained in
this Agreement on the part  of Parent or Merger  Sub, then, within two  business
days  following such termination by the Company, Parent shall pay to the Company
by wire  transfer of  immediately available  funds  the sum  of $12  million  as
liquidated  damages  for the  breach giving  rise  to such  termination. Nothing
herein shall limit the liability of  Parent for any knowing or willful  breaches
of  any  representation,  warranty,  covenant  or  agreement  contained  in this
Agreement on the part of Parent.

    8.4  AMENDMENT.  Except as is otherwise required by applicable law after the
stockholders of  the  Company approve  this  Agreement, this  Agreement  may  be
amended  by the  parties hereto  at any  time by  execution of  an instrument in
writing signed on behalf of each of the parties hereto.

    8.5  EXTENSION; WAIVER.  At any time prior to the Effective Time, Parent and
Merger Sub, on the one hand, and the  Company, on the other, may, to the  extent
legally  allowed,  (i)  extend  the  time for  the  performance  of  any  of the
obligations of  the other  party  hereto, (ii)  waive  any inaccuracies  in  the
representations  and warranties  made to such  party contained herein  or in any
document delivered pursuant hereto, and (iii)  waive compliance with any of  the
agreements  or conditions  for the benefit  of such party  contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set  forth in an  instrument in writing signed  on behalf of  such
party.

    9.4    ENTIRE  AGREEMENT; ASSIGNMENT.    This Agreement,  the  schedules and
Exhibits hereto, and the  documents and instruments  and other agreements  among
the  parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect  to the subject matter  hereof and supersede all  prior

other  person any rights or remedies hereunder; and (c) shall not be assigned by
operation of law or otherwise except as otherwise specifically provided,  except

    9.5  SEVERABILITY.  In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to  be  illegal, void  or unenforceable,  the remainder  of this  Agreement will
continue in full force and effect and the application of such provision to other
persons or circumstances  will be  interpreted so  as reasonably  to effect  the
intent  of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve,  to the  extent possible,  the economic,  business and  other
purposes of such void or unenforceable provision.

    9.6   OTHER  REMEDIES.   Except as  otherwise provided  herein, any  and all
remedies herein expressly conferred upon a party will be deemed cumulative  with

exercise of any other remedy.

waives  and covenants  not to  assert or  plead any  objection which  they might
otherwise have to such jurisdiction and such process.

    9.8  RULES OF CONSTRUCTION.   The parties hereto  agree that they have  been
represented  by counsel during  the negotiation and  execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in  an agreement or other document  will
be construed against the party drafting such agreement or document.

    9.9  SPECIFIC PERFORMANCE.  The parties hereto agree that irreparable damage
would  occur in the event that any of  the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed  that the parties  shall be entitled  to an injunction  or
injunctions  to prevent breaches  of this Agreement  and to enforce specifically
the terms and provisions hereof in any  court of the United States or any  state
having  jurisdiction, this being in  addition to any other  remedy to which they
are entitled at law or in equity.

                                  SECTION 262
                        DELAWARE GENERAL CORPORATION LAW
                                APPRAISAL RIGHTS

    262  APPRAISAL RIGHTS.  (a)  Any stockholder of a  corporation of this State
who holds shares  of stock on  the date of  the making of  a demand pursuant  to
subsection  (d) of  this section with  respect to such  shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d)  of this section and who has  neither
voted  in favor of the merger or  consolidation nor consented thereto in writing
pursuant to Section228 of this  title shall be entitled  to an appraisal by  the
Court  of  Chancery  of  the  fair  value  of  his  shares  of  stock  under the
circumstances described in subsections (b) and  (c) of this section. As used  in
this  section, the  word "stockholder" means  a holder  of record of  stock in a
stock corporation and  also a member  of record of  a nonstock corporation;  the
words  "stock" and "share"  mean and include  what is ordinarily  meant by those
words and  also membership  or membership  interest of  a member  of a  nonstock
corporation;  and  the  words  "depository  receipt"  mean  a  receipt  or other
instrument issued  by a  depository  representing an  interest  in one  or  more
shares,  or fractions thereof, solely of stock  of a corporation, which stock is
deposited with the depository.

    (b) Appraisal  rights shall  be available  for the  shares of  any class  or
series  of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section251, 252, 254, 257, 258, 263 or 264 of this title:

        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository receipts  in  respect  thereof,  at  the  record  date  fixed  to
    determine  the stockholders entitled to receive notice of and to vote at the
    meeting  of  stockholders  to  act  upon  the  agreement  of  a  merger   or
    consolidation,  were either (i) listed on  a national securities exchange or
    designated as a national market systems security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii)  held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights  shall  be  available for  any  shares  of stock  of  the constituent
    corporation surviving a merger if the merger did no require for its approval
    the vote of  the holders  of the surviving  corporation as  provided in  (1)
    SUBSECTIONS (F) OR (G) of Section251 of this title.

        (2)  Notwithstanding paragraph (1) of  this subsection, appraisal rights
    under this section shall be available for the shares of any class or  series
    of stock of a constituent corporation if the holders thereof are required by
    the   terms  of  an  agreement  of   merger  or  consolidation  pursuant  to
    SectionSection251, 252, 254, 257, 258, 263  and 264 of this title to  accept
    for such stock anything except:

            a.  Shares of stock  of the corporation  surviving or resulting from
       such merger or consolidation, or depository receipts in respect thereof;

            b. Shares of stock of any other corporation, or depository  receipts
       in  respect thereof, which shares of  stock or depository receipts at the
       effective date of the merger or consolidation will be either listed on  a
       national  securities exchange or  designated as a  national market system
       security on an interdealer quotation  system by the National  Association
       of Securities Dealers, Inc. or held of record by more than 2,000 holders;

            c.  Cash  in  lieu  of fractional  shares  or  fractional depository
       receipts described  in the  foregoing  subparagraphs a.  and b.  of  this
       paragraph; or

            d.  Any combination of the shares  of stock, depository receipts and
       cash in  lieu  of fractional  shares  or fractional  depository  receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.

                                      B-1
<PAGE>
        (3)  In the event all of the  stock of a subsidiary Delaware corporation
    party to a  merger effected  under 253  of this title  is not  owned by  the
    parent  corporation immediately prior to  the merger, appraisal rights shall
    be available for the shares of the subsidiary Delaware corporation.

    (c) Any corporation  may provide  in its certificate  of incorporation  that
appraisal  rights under this  section shall be  available for the  shares of any
class or series of its stock as a  result of an amendment to its certificate  of
incorporation,  any  merger  or  consolidation in  which  the  corporation  is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a  provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

    (d) Appraisal rights shall be perfected as follows:

        (1) If a proposed merger or consolidation for which appraisal rights are
    provided  under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than  20 days prior to the  meeting,
    shall  notify each of its  stockholders who was such  on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to  subsections  (b)  and  (c) hereof  that  appraisal  rights  are
    available  for any or all of the shares of the constituent corporations, and
    shall include  in such  notice  a copy  of  this section.  Each  stockholder
    electing  to  demand  the  appraisal  of his  shares  shall  deliver  to the
    corporation, before the taking of the vote on the merger or consolidation, a
    written demand for appraisal of his  shares. Such demand will be  sufficient
    if  it reasonably informs the corporation of the identity of the stockholder
    and that the  stockholder intends  thereby to  demand the  appraisal of  his
    shares.  A  proxy or  vote  against the  merger  or consolidation  shall not
    constitute such a demand. A stockholder electing to take such action must do
    so by a separate written demand as herein provided. Within 10 days after the
    effective date of such merger  or consolidation, the surviving or  resulting
    corporation  shall notify  each stockholder of  each constituent corporation
    who has complied  with this  subsection and  has not  voted in  favor of  or
    consented  to the  merger or  consolidation of the  date that  the merger or
    consolidation has become effective; or

        (2) If the merger or  consolidation was approved pursuant to  Section228
    or  253 of this title, the surviving or resulting corporation, either before
    the effective  date  of  the  merger or  consolidation  or  within  10  days
    thereafter,  shall  notify each  of the  stockholders entitled  to appraisal
    rights of  the  effective date  of  the  merger or  consolidation  and  that
    appraisal  rights  are  available  for  any or  all  of  the  shares  of the
    constituent corporation, and  shall include in  such notice a  copy of  this
    section.  The notice shall  be sent by certified  or registered mail, return
    receipt requested, addressed to the stockholder at his address as it appears
    on the records  of the  corporation. Any stockholder  entitled to  appraisal
    rights  may, within 20 days after the  date of mailing of the notice, demand
    in writing from the surviving or resulting corporation the appraisal of  his
    shares.  Such  demand  will  be  sufficient  if  it  reasonably  informs the
    corporation of  the identity  of the  stockholder and  that the  stockholder
    intends thereby to demand the appraisal of his shares.

    (e) Within 120 days after the effective date of the merger or consolidation,
the  surviving or resulting corporation or any stockholder who has complied with
subsections (a)  and (d)  hereof  and who  is  otherwise entitled  to  appraisal
rights,  may file a petition in the  Court of Chancery demanding a determination
of the  value  of  the  stock of  all  such  stockholders.  Notwithstanding  the
foregoing,  at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the  right to withdraw his demand  for
appraisal  and to  accept the  terms offered  upon the  merger or consolidation.
Within 120 days  after the effective  date of the  merger or consolidation,  any
stockholder  who has complied  with the requirements of  subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the  corporation
surviving  the merger  or resulting from  the consolidation  a statement setting
forth the  aggregate number  of  shares not  voted in  favor  of the  merger  or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after

                                      B-2
<PAGE>
his  written  request for  such  a statement  is  received by  the  surviving or
resulting corporation  or within  10 days  after expiration  of the  period  for
delivery  of demands  for appraisal  under subsection  (d) hereof,  whichever is
later.

    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the  surviving or resulting corporation, which  shall
within 20 days after such service file in the office of the Register in Chancery
in  which the petition was  filed a duly verified  list containing the names and
addresses of all  stockholders who have  demanded payment for  their shares  and
with  whom agreements as to  the value of their shares  have not been reached by
the surviving or resulting  corporation. If the petition  shall be filed by  the
surviving  or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court,  shall
give  notice of  the time and  place fixed for  the hearing of  such petition by
registered or certified mail  to the surviving or  resulting corporation and  to
the  stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by one or more publications at least one week before the day
of the hearing, in a newspaper of  general circulation published in the City  of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of  the notices by mail  and by publication shall be  approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

    (g) At  the  hearing  on  such  petition,  the  Court  shall  determine  the
stockholders who have complied with this section and who have become entitled to
appraisal  rights. The Court  may require the stockholders  who have demanded an
appraisal for their  shares and who  hold stock represented  by certificates  to
submit  their certificates  of stock  to the  Register in  Chancery for notation
thereon of the  pendency of the  appraisal proceedings; and  if any  stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

    (h)  After determining the stockholders entitled  to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value  arising  from the  accomplishment  or  expectation of  the  merger  or
consolidation,  together with a fair  rate of interest, if  any, to be paid upon
the amount determined to be the fair value. In determining such fair value,  the
Court shall take into account all relevant factors. In determining the fair rate
of  interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting  corporation would have had to pay  to
borrow  money during  the pendency  of the  proceeding. Upon  application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit  discovery
or  other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final  determination of  the stockholder  entitled to  an appraisal.  Any
stockholder  whose name appears on the list  filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock  to the  Register in Chancery,  if such  is required,  may
participate  fully in all proceedings until it  is finally determined that he is
not entitled to appraisal rights under this section.

    (i) The Court  shall direct the  payment of  the fair value  of the  shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders  entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be  so make to each such  stockholder, in the case  of
holders  of uncertificated  stock forthwith, and  the case of  holders of shares
represented by  certificates  upon  the  surrender to  the  corporation  of  the
certificates  representing such  stock. The  Court's decree  may be  enforced as
other decrees in the Court of  Chancery may be enforced, whether such  surviving
or resulting corporation be a corporation of this State or of any state.

     (j)  The costs of the  proceeding may be determined  by the Court and taxed
upon the  parties  as the  Court  deems  equitable in  the  circumstances.  Upon
application  of  a stockholder,  the Court  may order  all or  a portion  of the
expenses  incurred  by  any  stockholder   in  connection  with  the   appraisal
proceeding,  including, without  limitation, reasonable attorney's  fees and the
fees and expenses of experts,  to be charged pro rata  against the value of  all
the shares entitled to an appraisal.

                                      B-3
<PAGE>
    (k)  From and after  the effective date  of the merger  or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection  (d)
of  this section  shall be  entitled to vote  such stock  for any  purpose or to
receive payment  of  dividends  or  other distributions  on  the  stock  (except
dividends  or other  distributions payable to  stockholders of record  at a date
which is prior to the effective date of the merger or consolidation);  provided,
however,  that if no  petition for an  appraisal shall be  filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within  60
days  after the  effective date  of the merger  or consolidation  as provided in
subsection (e) of this  section or thereafter with  the written approval of  the
corporation,  then the  right of such  stockholder to an  appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of  Chancery
shall  be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

    (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders  would have been converted  had they assented  to
the  merger or  consolidation shall have  the status of  authorized and unissued
shares of the surviving  or resulting corporation. (Last  amended by Ch. 79,  L.
'95, eff. 7-1-95.)

                                   CHAPTER 13
                       CALIFORNIA GENERAL CORPORATION LAW
                               DISSENTERS' RIGHTS

SECTION 1300.  RIGHT TO REQUIRE PURCHASE; "DISSENTING SHARES" AND "DISSENTING
STOCKHOLDER" DEFINED.

    (a) If the approval of the outstanding shares (Section 152) of a corporation
is  required for a reorganization under  subdivisions (a) and (b) or subdivision
(e) of Section 1201,  each stockholder of such  corporation entitled to vote  on
the transaction and each stockholder of a subsidiary corporation in a short-form
merger may, by complying with this chapter, require the corporation in which the
stockholder  holds shares to  purchase for cash  at their fair  market value the
shares owned  by the  stockholder  which are  dissenting  shares as  defined  in
subdivision  (b). The fair market value shall be determined as of the day before
the first announcement of the terms of the proposed reorganization or short-form
merger, excluding  any  appreciation  or  depreciation  in  consequence  of  the
proposed  action,  but adjusted  for  any stock  split  or share  dividend which
becomes effective thereafter.

    (b) As used  in this chapter,  "dissenting shares" means  shares which  come
within all of the following descriptions:

        (1) Which were not immediately prior to the reorganization or short-form
    merger  either (A) listed  on any national  securities exchange certified by
    the Commissioner of Corporations under  subdivision (0) of Section 25100  or
    (B) listed on the list of OTC margin stocks issued by the Board of Governors
    of  the Federal Reserve System, and the notice of meeting of stockholders to
    act upon the reorganization summarizes this section and Sections 1301, 1302,
    1303 and 1304; provided, however, that this provision does not apply to  any
    shares  with  respect  to which  there  exists any  restriction  on transfer
    imposed by  the corporation  or  by any  law  or regulation;  and  provided,
    further, that this provision does not apply to any class of shares described
    in  subparagraph (A) or (B) if demands for payment are filed with respect to
    five percent or more of the outstanding shares of that class.

        (2) Which  were  outstanding  on  the  date  for  the  determination  of
    stockholders  entitled to vote on the  reorganization and (A) were not voted
    in favor of the reorganization or,  (B) if described in subparagraph (A)  or
    (B)  of paragraph  (1) (without regard  to the provisos  in that paragraph),
    were voted against the reorganization, or  which were held of record on  the
    effective  date of a short-form merger; provided, however, that subparagraph
    (A) rather than subparagraph (B) of this paragraph applies in any case where
    the approval required by  Section 1201 is sought  by written consent  rather
    than at a meeting.

        (3)  Which the dissenting stockholder  has demanded that the corporation
    purchase at their fair market value, in accordance with Section 1301.

        (4) Which the dissenting stockholder  has submitted for endorsement,  in
    accordance with Section 1301.

    (c) As used in this chapter, "dissenting stockholder" means the recordholder
of dissenting shares and includes a transferee of record.

SECTION 1301.  DEMAND FOR PURCHASE.

    (a)  If, in the case of a  reorganization, any stockholders of a corporation
have a right under Section 1300,  subject to compliance with paragraphs (3)  and
(4)  of subdivision  (b) thereof, to  require the corporation  to purchase their
shares for cash, such corporation shall  mail to each such stockholder a  notice
of  the approval of  the reorganization by its  outstanding shares (Section 152)
within ten (10) days alter  the date of such approval  accompanied by a copy  of
Sections  1300, 1302,  1303, 1304  and this  section, a  statement of  the price
determined  by   the   corporation   to  represent   the   fair   market   value

                                      C-1
<PAGE>
of  the  dissenting shares,  and  a brief  description  of the  procedure  to be
followed if the stockholder  desires to exercise the  stockholder s right  under
such sections. The statement of price constitutes an offer by the corporation to
purchase at the price stated any dissenting shares as defined in subdivision (b)
of  Section  1300, unless  they  lose their  status  as dissenting  shares under
Section 1309.

    (b) Any stockholder who has a  right to require the corporation to  purchase
the stockholder s shares for cash under Section 1300, subject to compliance with
paragraphs  (3)  and  (4)  of  subdivision  (b)  thereof,  and  who  desires the
corporation  to  purchase  such  shares  shall  make  written  demand  upon  the
corporation  for the purchase of  such shares and payment  to the stockholder in
cash of their fair  market value. The  demand is not  effective for any  purpose
unless  it is received by  the corporation or any  transfer agent thereof (1) in
the case  of  shares  described in  clause  (i)  or (ii)  of  paragraph  (1)  of
subdivision  (b)  of  Section  1300  (without regard  to  the  provisos  in that
paragraph), not later than the date of the stockholders meeting to vote upon the
reorganization, or (2) in any other case within thirty (30) days alter the  date
on  which  the notice  of the  approval  by the  outstanding shares  pursuant to
subdivision (a) or the  notice pursuant to subdivision  (i) of Section 1110  was
mailed to the stockholder.

    (c) The demand shall state the number and class of the shares held of record
by  the stockholder which the stockholder  demands that the corporation purchase
and shall contain a  statement of what  such stockholder claims  to be the  fair
market  value  of those  shares as  of the  day before  the announcement  of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the stockholder to sell the shares at such price.

SECTION 1302.  ENDORSEMENT OF SHARES.

    Within thirty (30) days alter  the date on which  notice of the approval  by
the outstanding shares or the notice pursuant to subdivision (i) of Section 1110
was  mailed to the stockholder, the  stockholder shall submit to the corporation
at its principal office or at the  office of any transfer agent thereof, (a)  if
the   shares  are   certificated  securities,   the  stockholder's  certificates
representing any  shares  which the  stockholder  demands that  the  corporation
purchase,  to  be stamped  or  endorsed with  a  statement that  the  shares are
dissenting  shares  or   to  be  exchanged   for  certificates  of   appropriate
denomination  so stamped  or endorsed  or (b)  if the  shares are uncertificated
securities, written notice of the number of shares which the stockholder demands
that the  corporation  purchase. Upon  subsequent  transfers of  the  dissenting
shares   on  the  books  of  the  corporation,  the  new  certificates,  initial
transaction statement, and other written statements issued therefor shall bear a
like statement, together with the name of the original dissenting holder of  the
shares.

SECTION 1303.  AGREED PRICE; TIME FOR PAYMENT.

    (a)  If  the  corporation and  the  stockholder  agree that  the  shares are
dissenting shares  and  agree upon  the  price  of the  shares,  the  dissenting
stockholder  is entitled to the agreed price  with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

    (b) Subject to the  provisions of Section 1306,  payment of the fair  market
value  of dissenting  shares shall  be made  within thirty  (30) days  after the
amount thereof has been agreed or within thirty (30) days after any statutory or
contractual conditions to the reorganization are satisfied, whichever is  later,
and  in  the  case  of  certificated securities,  subject  to  surrender  of the
certificates therefor, unless provided otherwise by agreement.

SECTION 1304.  DISSENTER'S ACTION TO ENFORCE PAYMENT.

    (a) If the corporation denies that the shares are dissenting shares, or  the
corporation  and the stockholder fail to agree upon the fair market value of the
shares, then the  stockholder demanding  purchase of such  shares as  dissenting
shares  or any interested corporation,  within six (6) months  after the date on
which notice of the approval by  the outstanding shares (Section 152) or  notice
pursuant  to subdivision (i) of Section 1110  was mailed to the stockholder, but
not thereafter, may file a complaint

                                      C-2
<PAGE>
in the  superior court  of the  proper  county praying  the court  to  determine
whether  the  shares are  dissenting  shares or  the  fair market  value  of the
dissenting shares or  both or  may intervene  in any  action pending  on such  a
complaint.

    (b)  Two or more dissenting stockholders may join as plaintiffs or be joined
as defendants  in  any  such  action  and  two  or  more  such  actions  may  be
consolidated.

    (c) On the trial of the action, the court shall determine the issues. If the
status  of the shares  as dissenting shares  is in issue,  the court shall first
determine that issue. If the  fair market value of  the dissenting shares is  in
issue,  the  court  shall determine,  or  shall  appoint one  or  more impartial
appraisers to determine, the fair market value of the shares.

SECTION 1305.  APPRAISER'S REPORT; PAYMENT; COSTS.

    (a) If the  court appoints an  appraiser or appraisers,  they shall  proceed
forthwith to determine the fair market value per share. Within the time fixed by
the  court, the appraisers, or a majority of  them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any  party,
the  report shall be submitted  to the court and  considered on such evidence as
the court considers  relevant. If  the court  finds the  report reasonable,  the
court may confirm it.

    (b) If a majority of the appraisers appointed fail to make and file a report
within  ten (10) days from the date  of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

    (c) Subject to the  provisions of Section 1306,  judgment shall be  rendered
against  the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting stockholder who  is a party,  or who has  intervened, is entitled  to
require  the corporation  to purchase, with  interest thereon at  the legal rate
from the date on which judgment was entered.

    (d)  Any  such  judgment  shall   be  payable  forthwith  with  respect   to
uncertificated  securities and,  with respect  to certificated  securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

    (e) The  costs  of the  action,  including reasonable  compensation  to  the
appraisers  to be fixed  by the court,  shall be assessed  or apportioned as the
court considers equitable, but,  if the appraisal exceeds  the price offered  by
the  corporation,  the  corporation  shall  pay  the  costs  (including  in  the
discretion of the court attorneys' fees,  fees of expert witnesses and  interest
at  the legal rate on judgments from  the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than  125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

SECTION 1306.  DISSENTING STOCKHOLDER'S STATUS AS CREDITOR.

    To  the extent that the  provisions of Chapter 5  prevent the payment to any
holders of  dissenting shares  of their  fair market  value, they  shall  become
creditors  of the corporation  for the amount thereof  together with interest at
the legal rate on judgments  until the date of  payment, but subordinate to  all
other  creditors in  any liquidation  proceeding, such  debt to  be payable when
permissible under the provisions of Chapter 5.

SECTION 1307.  DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.

    Cash dividends  declared and  paid by  the corporation  upon the  dissenting
shares  after  the date  of approval  of the  reorganization by  the outstanding
shares (Section 152)  and prior  to payment for  the shares  by the  corporation
shall  be  credited against  the  total amount  to  be paid  by  the corporation
therefor.

                                      C-3
<PAGE>
SECTION 1308.  CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING STOCKHOLDERS.

    Except as expressly limited  in this chapter,  holders of dissenting  shares
continue  to have all the rights and  privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
stockholder may  not  withdraw  a  demand for  payment  unless  the  corporation
consents thereto.

SECTION 1309.  TERMINATION OF DISSENTING STOCKHOLDER STATUS.

    Dissenting  shares lose  their status as  dissenting shares  and the holders
thereof cease to be dissenting stockholders and cease to be entitled to  require
the  corporation  to purchase  their shares  upon  the happening  of any  of the
following:

        (a) The corporation abandons the reorganization. Upon abandonment of the
    reorganization, the  corporation  shall  pay on  demand  to  any  dissenting
    stockholder  who has initiated proceedings in  good faith under this chapter
    all necessary expenses incurred in such proceedings and reasonable attorneys
    fees.

        (b) The shares are transferred prior to their submission for endorsement
    in accordance  with Section  1302  or are  surrendered for  conversion  into
    shares of another class in accordance with the articles.

        (c) The dissenting stockholder and the corporation do not agree upon the
    status  of the shares as dissenting shares or upon the purchase price of the
    shares, and neither files a complaint  or intervenes in a pending action  as
    provided  in Section  1304, within  six (6) months  after the  date on which
    notice of  the approval  by the  outstanding shares  or notice  pursuant  to
    subdivision (i) of Section 1110 was mailed to the stockholder.

        (d)  The dissenting  stockholder, with  the consent  of the corporation,
    withdraws the stockholder s demand for purchase of the dissenting shares.

SECTION 1310.  SUSPENSION OF PROCEEDINGS FOR PAYMENT PENDING LITIGATION.

    If litigation is  instituted to test  the sufficiency or  regularity of  the
votes of the stockholders in authorizing a reorganization, any proceedings under
Sections  1304 and  1305 shall  be suspended  until final  determination of such
litigation.

SECTION 1311.  EXEMPT SHARES.

    This chapter, except Section 1312, does not apply to classes of shares whose
terms and provisions specifically set forth the amount to be paid in respect  to
such shares in the event of a reorganization or merger.

SECTION 1312.  ATTACKING VALIDITY OF REORGANIZATION OR MERGER.

    (a)  No stockholder of a  corporation who has a  right under this chapter to
demand payment of cash  for the shares  held by the  stockholder shall have  any
right  at  law or  in equity  to attack  the validity  of the  reorganization or
short-form merger, or to have the reorganization or short-form merger set  aside
or  rescinded, except in an action to test whether the number of shares required
to authorize or  approve the  reorganization have  been legally  voted in  favor
thereof;  but  any  holder of  shares  of  a class  whose  terms  and provisions
specifically set forth the amount to be paid in respect to them in the event  of
a  reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization  are
approved  pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

    (b) If  one of  the parties  to  a reorganization  or short-form  merger  is
directly  or indirectly  controlled by,  or under  common control  with, another
party to  the reorganization  or short-form  merger, subdivision  (a) shall  not
apply  to any stockholder of such party who has not demanded payment of cash for
such stockholder's  shares pursuant  to  this chapter;  but if  the  stockholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization

                                      C-4
<PAGE>
or  short-form  merger  set  aside  or  rescinded,  the  stockholder  shall  not
thereafter have any right to demand payment of cash for the stockholder s shares
pursuant to this chapter. The court in any action attacking the validity of  the
reorganization  or short-form merger or to have the reorganization or short-form
merger set aside or rescinded shall  not restrain or enjoin the consummation  of
the  transaction except upon ten (10) days'  prior notice to the corporation and
upon a determination by the court  that clearly no other remedy will  adequately
protect  the complaining stockholder or the  class of stockholders of which such
stockholder is a member.

    (c) If  one of  the parties  to  a reorganization  or short-form  merger  is
directly or indirectly controlled by or under common control with, another party
to the reorganization or short-form merger, in any action to attack the validity
of  the reorganization  or short-form  merger or  to have  the reorganization or
short-form merger set  aside or rescinded,  (1) a party  to a reorganization  or
short-form  merger  which  controls  another  party  to  the  reorganization  or
short-form merger shall have the burden of proving that the transaction is  just
and  reasonable as to the stockholders of the controlled party, and (2) a person
who controls two or more  parties to a reorganization  shall have the burden  of
proving  that the transaction is  just and reasonable as  to the stockholders of
any party so controlled.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section  145 of the  Delaware General Corporation Law  authorizes a court to
award, or  a  corporation's Board  of  Directors to  grant,  indemnification  to
directors   and   officers  in   terms   sufficiently  broad   to   permit  such
indemnification  under   certain   circumstances  for   liabilities   (including
reimbursement  for expenses incurred) arising  under the Securities Act. Article
Eight of the Registrant's Certificate of Incorporation (Exhibit 3.1 hereto)  and
Article  VI  of  the  Registrant's  Bylaws  (Exhibit  3.2  hereto)  provide  for
indemnification of its directors,  officers, employees and  other agents to  the
maximum  extent permitted by  the Delaware Law. In  addition, the Registrant has
entered into Indemnification Agreements (Exhibit 10.11 hereto) with its officers
and directors.

    The Merger Agreement provides that commencing with the effectiveness of  the
Merger,  the Registrant will  either cause Illustra to,  or will itself directly
indemnify the  current officers  and directors  of Illustra  in accordance  with
Illustra's  Bylaws in  effect immediately  before the  Merger for  any action or
inaction by such person prior to the Merger.

ITEM 22.  UNDERTAKINGS

    (1)  The undersigned Registrant hereby undertakes  as follows: that prior to
any public reoffering of  the securities registered hereunder  through use of  a
prospectus  which is  a part  of this Registration  Statement, by  any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),  the
undersigned  Registrant undertakes that such  reoffering prospectus will contain
the information called for by the  applicable registration form with respect  to
reofferings  by  persons who  may  be deemed  underwriters,  in addition  to the
information called for by the other Items of the applicable form.

    (2) The  Registrant  undertakes that  every  prospectus (i)  that  is  filed
pursuant  to paragraph (1) immediately preceding,  or (ii) that purports to meet
the requirements of Section 10(a)(3) of the  Act and is used in connection  with
an  offering of securities  subject to Rule 415,  will be filed as  a part of an
amendment to  the  Registration  Statement  and will  not  be  used  until  such
amendment  is effective,  and that,  for purposes  of determining  any liability
under the Securities Act  of 1933, 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)  Insofar  as  the  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be  permitted to Directors, officers and  controlling
persons  of the Registrant  pursuant to the  foregoing provisions, or otherwise,
the Registrant  has been  advised that  in  the opinion  of the  Securities  and
Exchange  Commission such indemnification is  against public policy as expressed
in the Act  and is,  therefore, unenforceable.  In the  event that  a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses incurred  or paid by a  director, officer or  controlling
person  of  the Registrant  in the  successful  defense of  any action,  suit or
proceeding) is  asserted by  such  director, officer  or controlling  person  in
connection  with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to  a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

    (4) The undersigned Registrant hereby undertakes to respond to requests  for
information  that is incorporated  by reference into  the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within

                                      II-2
<PAGE>
one business  day of  receipt of  such  request, and  to send  the  incorporated
documents  by  first class  mail or  other equally  prompt means.  This includes
information contained in documents filed subsequent to the effective date of the
Registration Statement through the date of responding to the request.

    The undersigned  Registrant  hereby  undertakes  to supply  by  means  of  a
post-effective  amendment  all  information concerning  a  transaction,  and the
company being  acquired  involved therein,  that  was  not the  subject  of  and
included in the Registration Statement when it became effective.

Registrant has duly caused this Amendment to Registration Statement to be signed
on its behalf  by the  undersigned, thereunto duly  authorized, in  the City  of

Ladies and Gentlemen:

    This  opinion is being delivered to you in connection with the Agreement and
Plan of Reorganization dated December 20, 1995 (the "Reorganization  Agreement")
by  and among Informix Corporation,  a Delaware corporation ("Parent"), Informix
Delaware, Inc., a  Delaware corporation  and wholly owned  subsidiary of  Parent
("Merger   Sub")  and  Illustra  Information   Technologies,  Inc.,  a  Delaware
corporation (the  "Company").  Merger  Sub  will merge  into  the  Company  (the
"Merger")  pursuant  to the  Reorganization Agreement  and related  Agreement of
Merger to be filed by Merger Sub and the Company with the Secretary of State  of
Delaware  on the Closing Date (collectively, including the exhibits to each, the
"Agreements").

    Except as otherwise provided, capitalized terms not defined herein have  the
meanings  set forth  in the  Reorganization Agreement  or in  certificates dated
           , 1996  delivered  to  us  by Parent,  Merger  Sub  and  the  Company
containing  certain representations of  Parent, Merger Sub  and the Company (the
"Certificates of  Representations"). All  section references,  unless  otherwise
indicated, are to the Internal Revenue Code of 1986, as amended (the "Code").

    We  have acted as counsel to Parent  in connection with the Merger. As such,
and for  the purpose  of rendering  this opinion,  we have  examined  originals,
certified  copies or  copies otherwise identified  to our  satisfaction as being
true copies of the original of  the following documents (including all  exhibits
and schedules attached thereto):

        (a) the Agreements;

        (b)  the Registration  Statement on  Form S-4  filed by  Parent with the
    Securities and Exchange Commission (the "Registration Statement");

        (c) the Certificates of Representations;

        (d) Affiliates Agreements entered into by certain Company  stockholders;
    and

        (e)  such  other instruments  and  documents related  to  the formation,
    organization and operation of Parent, Merger Sub and the Company and related
    to the consummation of the Merger and the transactions contemplated  thereby
    as we have deemed necessary or appropriate.

    In  connection with  rendering this  opinion, we  have assumed  (without any
independent investigation or review thereof):

    1.   Original  documents  (including signatures)  are  authentic,  documents
submitted  to us as copies  conform to the original  documents, and there is (or
will be prior to the Closing) due execution and delivery of all documents  where
due execution and delivery are a prerequisite to the effectiveness thereof;

    2.   The truth and  accuracy at all relevant  times, of all representations,
warranties and  statements made  or agreed  to  by Parent,  Merger Sub  and  the
Company,  their managements, employees, officers,  directors and stockholders in
connection with the Merger, including but not limited to those set forth in  the
Agreements (including the exhibits) and the Certificates of Representations; and
that  all covenants contained in such agreements are performed without waiver or
breach of any material provision thereof; and

    3.  There is no plan or intention on the part of the Company's  stockholders
to  engage  in  a  sale,  exchange,  transfer,  distribution,  pledge  or  other
disposition (including a distribution by  a corporation to its stockholders)  or
any  transaction which would  result in a  reduction of risk  of ownership, or a
direct or indirect disposition (a "Sale") of shares of Parent Common Stock to be
received in the Merger that would reduce the Company stockholders' ownership  of
Parent Common Stock to a number of shares having an aggregate fair market value,
as of the Effective Time, of less than fifty percent (50%) of the aggregate fair
market  value of all of the capital stock of the Company outstanding immediately
prior to the consummation of the Merger. Shares of the Company capital stock (a)
with respect to which dissenters' rights are exercised in the Merger, (b)  which
are  exchanged for cash in  lieu of fractional shares  of Parent Common Stock or
(c) which  are  sold, redeemed  or  disposed of  in  a transaction  that  is  in
contemplation of or related to the Merger, shall be considered shares of capital
stock  of the  Company which are  exchanged in  the Merger for  shares of Parent
Common Stock which are then disposed of pursuant to a plan.

    Based on  our  examination  of  the  foregoing  items  and  subject  to  the
limitations, qualifications, assumptions and caveats set forth herein, we are of
the opinion that:

    (a)  For  federal  income  tax  purposes,  the  Merger  will  qualify  as  a
"reorganization" as defined in Section 368(a) of the Code; and

    (b) The discussion entitled "Certain  Federal Income Tax Considerations"  in
the  Prospectus constituting a part of  the Registration Statement insofar as it
relates to the statements of law or legal conclusions is correct in all material
respects.

    This opinion  does not  address  the various  state,  local or  foreign  tax
consequences  that  may  result from  the  Merger.  In addition,  no  opinion is
expressed as  to any  federal income  tax consequence  of the  Merger except  as
specifically  set forth herein  and this opinion  may not be  relied upon except
with respect to the consequences specifically discussed herein.

    No opinion  is expressed  as to  any transaction  other than  the Merger  as
described in the Agreements or to any other transaction whatsoever including the
Merger  if all the transactions described  in the Agreements are not consummated
in accordance  with  the terms  of  the Agreements  and  without waiver  of  any
material   provision  thereof.  To  the   extent  any  of  the  representations,
warranties, statements and assumptions material to our opinion and upon which we
have relied  are  not complete,  correct,  true  and accurate  in  all  material
respects  at all  relevant times,  our opinion  would be  adversely affected and
should not be relied upon.

    This opinion only represents our best judgment as to the federal income  tax
consequences of the Merger and is not binding on the Internal Revenue Service or
the  courts. The conclusions are based on the Code, existing judicial decisions,
administration regulations and published rulings. No assurance can be given that
future legislative,  judicial  or  administrative changes  would  not  adversely
affect the accuracy of the conclusions stated herein. Nevertheless, by rendering
this  opinion,  we  undertake  no  responsibility  to  advise  you  of  any  new
developments in  the application  or interpretation  of the  federal income  tax
laws.

Dear Sir or Madam:

This opinion is being delivered to you in accordance with the Agreement and Plan
of  Reorganization dated December  20, 1995 (the  "Reorganization Agreement") by
and among  Informix Corporation,  a  Delaware corporation  ("Parent"),  Informix
Delaware,  Inc., a  Delaware corporation and  wholly owned  subsidiary of Parent
("Merger  Sub"),  and  Illustra  Information  Technologies,  Inc.,  a   Delaware
corporation  (the  "Company").  Merger  Sub will  merge  into  the  Company (the
"Merger") pursuant  to the  Reorganization Agreement  and related  Agreement  of
Merger  to be filed by Merger Sub and the Company with the Secretary of State of
Delaware on the Closing Date (collectively, including the exhibits to each,  the
"Agreements").

Except  as otherwise  provided, capitalized  terms not  defined herein  have the
meanings set  forth in  the Reorganization  Agreement or  in certificates  dated
February     ,  1996  delivered to  us  by Parent,  Merger  Sub and  the Company
containing certain representations of  Parent, Merger Sub  and the Company  (the
"Certificates  of  Representations"). All  section references,  unless otherwise
indicated, are to the Internal Revenue Code of 1986, as amended (the "Code").

We have acted as counsel to the Company in connection with the Merger. As  such,
and  for  the purpose  of rendering  this opinion,  we have  examined originals,
certified copies or  copies otherwise  identified to our  satisfaction as  being
true  copies of the original of  the following documents (including all exhibits
and schedules attached thereto):

    (a) the Agreements;

    (b) the  Registration  Statement  on  Form S-4  filed  by  Parent  with  the
Securities and Exchange Commission (the "Registration Statement");

    (c) the Certificates of Representations;

    (d) Affiliates Agreements entered into by certain Company stockholders; and

    (e)   such  other  instruments  and  documents  related  to  the  formation,
organization and operation of Parent, Merger Sub and the Company and related  to
the  consummation of the Merger and  the transactions contemplated thereby as we
have deemed necessary or appropriate.

In connection  with  rendering  this  opinion,  we  have  assumed  (without  any
independent investigation or review thereof):

    1.    Original  documents (including  signatures)  are  authentic, documents
submitted to us as copies  conform to the original  documents, and there is  (or
will  be prior to the Closing) due execution and delivery of all documents where
due execution and delivery are a prerequisite to the effectiveness thereof;

    2.  The truth  and accuracy at all  relevant times, of all  representations,
warranties  and  statements made  or agreed  to  by Parent,  Merger Sub  and the
Company, their managements, employees,  officers, directors and stockholders  in
connection  with the Merger, including but not limited to those set forth in the
Agreements (including the exhibits) and the Certificates of Representations; and
that all covenants contained in such agreements are performed without waiver  or
breach of any material provision thereof; and

    3.   There is no plan or intention on the part of the Company's stockholders
to  engage  in  a  sale,  exchange,  transfer,  distribution,  pledge  or  other
disposition  (including a distribution by a  corporation to its stockholders) or
any transaction which would  result in a  reduction of risk  of ownership, or  a
direct or indirect disposition (a "Sale") of shares of Parent Common Stock to be
received  in the Merger that would reduce the Company stockholders' ownership of
Parent Common Stock to a number of shares having an aggregate fair market value,
as of the Effective Time, of less than fifty percent (50%) of the aggregate fair
market value of all of the capital stock of the Company outstanding  immediately
prior to the consummation of the Merger. Shares of the Company capital stock (a)
with  respect to which dissenters' rights are exercised in the Merger, (b) which
are exchanged for cash in  lieu of fractional shares  of Parent Common Stock  or
(c)  which  are  sold, redeemed  or  disposed of  in  a transaction  that  is in
contemplation of or related to the Merger, shall be considered shares of capital
stock of the  Company which are  exchanged in  the Merger for  shares of  Parent
Common Stock which are then disposed of pursuant to a plan.

Based  on our examination of the foregoing items and subject to the limitations,
qualifications, assumptions and caveats set forth herein, we are of the  opinion
that:

    (a)  For  federal  income  tax  purposes,  the  Merger  will  qualify  as  a
"reorganization" as defined in Section 368(a) of the Code; and

    (b) The discussion entitled "Certain  Federal Income Tax Considerations"  in
the  Prospectus constituting a part of  the Registration Statement insofar as it
relates to the statements of law or legal conclusions is correct in all material
respects.

This  opinion  does  not  address  the  various  state,  local  or  foreign  tax
consequences  that  may  result from  the  Merger.  In addition,  no  opinion is
expressed as  to any  federal income  tax consequence  of the  Merger except  as
specifically  set forth herein  and this opinion  may not be  relied upon except
with respect to the consequences specifically discussed herein.

No opinion is expressed as to any transaction other than the Merger as described
in the Agreements or to any other transaction whatsoever including the Merger if
all the  transactions  described  in  the  Agreements  are  not  consummated  in
accordance  with the terms of the Agreements  and without waiver of any material
provision thereof.  To  the  extent  any  of  the  representations,  warranties,
statements and assumptions material to our opinion and upon which we have relied
are  not complete, correct,  true and accurate  in all material  respects at all
relevant times, our opinion would be adversely affected and should not be relied
upon.

This opinion only  represents our  best judgment as  to the  federal income  tax
consequences of the Merger and is not binding on the Internal Revenue Service or
the  courts. The conclusions are based on the Code, existing judicial decisions,
administration regulations and published rulings. No assurance can be given that
future legislative,  judicial  or  administrative changes  would  not  adversely
affect the accuracy of the conclusions stated herein. Nevertheless, by rendering
this  opinion,  we  undertake  no  responsibility  to  advise  you  of  any  new
developments in  the application  or interpretation  of the  federal income  tax
laws.

This  opinion may not be relied upon or utilized for any other purpose or by any
other person or entity, and may  not be distributed or otherwise made  available
to any other person or entity without our prior

"Certain Federal Income Tax Considerations" in the Registration Statement.
