(1) This Registration Statement relates to securities of the Registrant issuable
    to   Illustra  Information   Technologies,  Inc.,   a  Delaware  corporation
    ("Illustra"), in the proposed acquisition of Illustra by Registrant.
(2) There is no established trading market for the shares of Illustra which  are
    to  be converted into shares  of Common Stock of  the Registrant pursuant to
    the Merger described  herein. In  accordance with Rule  457(f)(2) under  the
    Securities  Act of 1933, as amended,  given that Illustra has an accumulated
    capital deficit,  the Proposed  Maximum Aggregate  Offering Price  has  been
    calculated  on  the basis  of one-third  of  the par  value of  the Illustra
    shares. One-third of such par  value was $527 on  January 2, 1996, the  most
    recent practicable date for determination.
(3)  In  accordance with  Section  6(b) under  the  Securities Act  of  1933, as
    amended, the registration fee is set at  the minimum amount for filing of  a
    registration statement.

STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH THE PROVISIONS OF
SECTION  8(A) OF THE SECURITIES ACT OF  1933 OR UNTIL THE REGISTRATION STATEMENT
SHALL BECOME EFFECTIVE ON SUCH DATE  AS THE COMMISSION, ACTING PURSUANT TO  SAID

time, at  Illustra's offices  located  at 1111  Broadway, Suite  2000,  Oakland,

    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  accompanying Notice  of Special  Meeting of  Stockholders and

    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

or Illustra Preferred Stock will become options and warrants to acquire Informix

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

                           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 0.77057  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   , 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   , 1996.

    SEE  "RISK  FACTORS"  AT PAGE  14  FOR  CERTAIN INFORMATION  THAT  SHOULD BE
CONSIDERED BY ILLUSTRA STOCKHOLDERS IN EVALUATING THE PROPOSAL TO BE VOTED ON AT
THE ILLUSTRA MEETING AND THE ACQUISITION OF THE SECURITIES OFFERED HEREBY.

NEITHER THIS TRANSACTION NOR THE SECURITIES OF INFORMIX OFFERED HEREBY HAVE BEEN
APPROVED OR DISAPPROVED BY THE SECURITIES  AND EXCHANGE COMMISSION OR ANY  STATE
SECURITIES  COMMISSION NOR  HAS THE  SECURITIES AND  EXCHANGE COMMISSION  OR ANY
STATE SECURITIES  COMMISSION  PASSED  UPON  THE ACCURACY  OR  ADEQUACY  OF  THIS
PROSPECTUS/PROXY  STATEMENT. ANY  REPRESENTATION TO  THE CONTRARY  IS A CRIMINAL
OFFENSE.

       THE DATE OF THIS PROSPECTUS/PROXY STATEMENT IS FEBRUARY   , 1996.

Illustra Common Stock and 38 stockholders of record of Illustra Preferred Stock.

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
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.

                                       2
<PAGE>
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 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 0.77057 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.

    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

                                       3
<PAGE>
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
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").

                                       4
<PAGE>
    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
  , 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 12,312,000  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  2,688,000
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.

    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 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.

    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
December  20, 1995, the last trading day before the announcement by Informix and
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
Merger, Informix Common  Stock will continue  to be traded  on Nasdaq under  the
symbol "IFMX." On January 9, 1996, the closing price of Informix Common Stock as
reported  on Nasdaq was $26.88. There can be no assurance as to the actual price
of Informix Common Stock  prior to, at  or at any  time following the  Effective
Time of the Merger. See "Risk Factors" and "Informix -- Informix Stock Price and
Dividend 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  mangagment  products. 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 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."

                                       6
<PAGE>
    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   58.8%   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 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.

                                       7
<PAGE>
    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 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, 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

                                       8
<PAGE>
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 three months ended September 30, 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, the 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  of  transaction costs  for  investment bankers  fees, attorneys,
    accountants, financial printing and other related charges, of  approximately
    $5.0  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.

    See Pro Forma Combined Condensed Financial Statements and the notes  thereto

                           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 of  transaction costs  for  investment bankers  fees,  attorneys,
    accountants,  financial printing and other related charges, of approximately
    $5.0 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  is  no assurance  that  stockholders  of
Illustra  would not  achieve greater returns  on investment if  Illustra were to
remain an independent company.

    NEED FOR 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 on 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
of  transaction  costs  for  investment  bankers  fees,  attorneys, accountants,
financial printing and other  related charges estimated  to be approximately  $5
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-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.

                                       15
<PAGE>
    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  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  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  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."

DATE, TIME AND PLACE OF ILLUSTRA MEETING

    The Illustra Meeting  will be  held at  Illustra's offices  located at  1111
Broadway,  Suite 2000, Oakland, California, on            , February   , 1996 at
9:00 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  84
stockholders  holding an aggregate of approximately 4,312,000 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."

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  58.8%  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 to  the Voting Agreements represent  66.4% of the votes
entitled to be cast by holders of shares of

                                       19
<PAGE>
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     , 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 0.77057 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 12,312,000 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
2,688,000 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

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:

        (a) enter into any commitment or transaction not in the ordinary  course
    of business;

        (b)   transfer  to  any  person  or  entity  any  rights  to  Illustra's

        (f) declare,  set  aside or  pay  any dividends  on  or make  any  other

    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
    securities convertible into, or  subscriptions, rights, warrants or  options
    to  acquire, or other agreements or  commitments of any character obligating
    it to issue any such shares or other convertible securities;

        (h) cause or permit any  amendments to its Certificate of  Incorporation
    or Bylaws;

    purchasing any assets or equity securities  of, or by any other manner,  any
    business  or  any corporation,  partnership,  association or  other business

    any  assets in  an amount  in excess  of $100,000  in the  case of  a single
    transaction or in excess of $200,000 in the aggregate in any 30-day period;

         (j) sell, lease, license or otherwise dispose of any of its  properties
    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
    any debt securities of others;

        (l)  Grant  any severance  or  termination pay  (i)  to any  director or
    officer or  (ii) to  any other  employee except  payments made  pursuant  to
    standard written agreements outstanding on the date hereof;

    employee benefit  plan,  or  enter  into  any  employment  contract,  extend
    employment  offers,  pay  or  agree  to pay  any  special  bonus  or special
    remuneration to any director or employee,  or increase the salaries or  wage
    rates  of its  employees, except as  consistent with the  ordinary course of

    any  equity  participation  in  Illustra  shall  be  agreed  in  advance  by
    Informix);

        (n) revalue any of its assets, including without limitation writing down
    the  value of  inventory or writing  off notes or  accounts receivable other
    than in the ordinary course of business;

        (o) pay, discharge or  satisfy, in an amount  in excess of $100,000  (in
    any  one  case) or  $250,000  (in the  aggregate),  any claim,  liability or
    obligation  (absolute,  accrued,  asserted  or  unasserted,  contingent   or
    otherwise),  other  than  the  payment,  discharge  or  satisfaction  in the
    ordinary course of business of liabilities reflected or reserved against  in
    the  Illustra financial statements attached to  the Merger Agreement or that
    arose in the ordinary course of business subsequent to September 30, 1995 or
    expenses consistent with the provisions of the Merger Agreement incurred  in
    connection with any transaction contemplated thereby;

        (p)  make or change any material election  in respect of taxes, adopt or
    change any accounting  method in respect  of taxes, enter  into any  closing
    agreement, settle any claim or assessment in respect of taxes, or consent to
    any  extension or waiver of the limitation period applicable to any claim or
    assessment in respect of taxes; or

        (q) take, or agree in writing or  otherwise to take, any of the  actions
    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.

covenants required by the Merger Agreement  to be performed or complied with  by
it  on or prior  to the Effective Time,  and Informix and  Merger Sub shall have
received a certificate  to such effect  signed by a  duly authorized officer  of
Illustra,  (c) Informix shall have received  a legal opinion from Cooley Godward
Castro Huddleson & Tatum, counsel to Illustra, (d) there shall not have occurred
any material adverse change (within the meaning of the Merger Agreement) in  the
business, assets, financial condition or results of operations of Illustra since
September  30, 1995;  (e) all  shares of Illustra  Series A  Preferred, Series B
Preferred and  Series D  Preferred  shall have  converted into  Illustra  Common
Stock, and the holder of the Illustra Series C Preferred shall have delivered to
Informix  an  irrevocable  election  to convert  such  Series  C  Preferred into
Illustra Common Stock, subject to and effective upon the closing of the  Merger,
(f)  certain employees of Illustra shall have signed and delivered to Informix a
non-competition agreements,  and such  agreements  shall be  in full  force  and
effect,  and (g) holders of no more  than five percent of the outstanding shares
of Illustra Capital Stock shall have exercised or continue to have the right  to
exercise appraisal or dissenters' rights.

TERMINATION OF MERGER AGREEMENT

    The Merger Agreement provides that it may be terminated at any time prior to
the Effective Time, whether before or after approval of the Merger by Illustra's
stockholders, (a) by mutual consent of Informix and Illustra, (b) by Informix or
Illustra  if: (i) the Effective Time has  not occurred by May 15, 1996 (provided
that the right to terminate the Merger Agreement under this clause (b) shall not
be available to any party whose willful failure to fulfill any obligation  under
the  Merger Agreement 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 Informix  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 Informix  or
Illustra's  ownership or operation of any portion of the business of Illustra or
(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 58.8% 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
(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

    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
who has not voted  in favor of approval  and adoption of the  Merger may file  a
complaint  in California superior court requesting a determination as to whether
the shares are Dissenting Shares or as to the fair market value of such holder's
shares of Illustra Capital Stock, or both.

               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.

           NOTES TO PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE 1.  PERIODS COMBINED

    The  unaudited Pro Forma Combined Condensed Statements of Income combine the
historical statements of income of Informix for the nine months ended October 1,
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:

                                                                        -----------
</TABLE>

    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  of  transaction  costs  for  investment  bankers  fees,   attorneys,
accountants, financial printing and other related

                                       44
<PAGE>
     NOTES TO PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS (CONTINUED)
                                  (UNAUDITED)
charges,  of approximately  $5.0 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 Informix s
database  products  developed  since  1983  support  Structured  Query  Language
("SQL"),  an  industry  standard  created by  IBM.  Informix  believes  that its
INFORMIX-Registered Trademark--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  6  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 34 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.

                                       46
<PAGE>
    - INFORMIX-OnLine   Extended  Parallel  Server,   a  new,  high-performance,
      scalable  database  server  which  extends  Informix's  Dynamic   Scalable
      Architecture to loosely coupled, "shared nothing" computing architectures,

      parallel processing systems.  This product became  available in the  third
      quarter of 1995 on a limited basis.

    - INFORMIX-SE,  designed for smaller organizations with limited MIS staffing
      or minimal database expertise because it is easy to install and  maintain.
      This  product  provides  the power  of  SQL without  the  complex database
      administration requirements.

    DATABASE TOOLS

    Informix offers a variety of database application development tools designed
to allow  users to  build applications  quickly and  maintain them  easily.  The
Informix database tools are:

      and flexible  application deployment,  and supports  open connectivity  to
      Informix   and  non-Informix   databases.  INFORMIX-NewEra   is  currently
      available  for   Microsoft-Registered  Trademark-   Windows-TM-  and   OSF
      Motif-TM-.

    - INFORMIX-4GL,  a character-based development environment, which includes a
      fourth-generation programming language  with full screen-building,  report
      entry  and  SQL  database  input/  output  capabilities.  The INFORMIX-4GL
      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 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

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
1,883 regular employees in  the North America region;  117 regular employees  in
the  Latin America region, 854 regular employees  in the Europe, Middle East and
Africa regions,  280 regular  employees  in the  Asia/  Pacific region  and  108
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
      larger numbers of concurrent users.

    - Adaptation  of  new products  to the  broad range  of computer  brands and
      operating systems Informix  currently supports and  adaptation of  current
      products  to new brands of computers and operating systems which represent
      attractive market opportunities for Informix products.

    There can be no assurance  that Informix's product development efforts  will
be  successful  or  that  any  new  products  will  achieve  significant  market
acceptance.

    As of  December 31,  1995, Informix  had 652  regular employees  engaged  in
research and development.

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  and suppliers  of third party  tools such as  Gupta Technologies, 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 3,242  regular
employees  worldwide, including  2,087 in sales,  marketing and  support; 652 in
research and  development;  90  in  operations and  413  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  200,000 square feet  of space in these  buildings. The leases for
spaces in three  of the  buildings expire in  April 1998.  The remaining  leases
expire in September 2001. Informix has an option to renew each lease for another
five year term at 95% of the then fair rental value.

    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  48 facilities  in the
United States and Canada and approximately 65 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 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

                                       53
<PAGE>
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
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

                                       54
<PAGE>
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
1995  in absolute dollars  compared to the same  period in 1994  was a result of
increased sales headcount worldwide, new  sales offices and increased  marketing
programs associated with new product introductions.

    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.

</TABLE>

    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.

                                       57
<PAGE>
    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

</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.

    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

COMPENSATION OF DIRECTORS

    For the  fiscal year  ended December  31, 1994,  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, 1995,  the outside Directors
will continue  to  receive the  same  compensation  as they  received  in  1994.
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 1994, 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 1994, and will  not in 1995, 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 800,000 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 1994,  Mr.  Yansouni  was  granted  an  option  for  15,000  shares  upon
re-election  to the Board which vests pro-rata over a three year period from the
date of grant. Assuming Messrs. Koch  and McDonnell are re-elected to the  Board
at  the 1995 Annual  Meeting, each will  be granted an  option for 15,000 shares
which will vest pro rata  over a three year period  from the date of the  grant.
Options

                                       71
<PAGE>
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.

    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.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

    The duty of the Compensation Committee  of Informix (the "Committee") is  to
set  and administer policies for Informix's compensation programs, which include
base and incentive pay  plans, stock option and  employee stock purchase  plans,
and  other employee  benefit plans. The  Committee is comprised  of four outside
members of the Board of Directors: Messrs. Knorp, Koch, McDonnell and Yansouni.

    Informix, at the  request of  the Committee,  has retained  the services  of
Towers  Perrin to  assist the  Committee in  connection with  its duties. Towers
Perrin has provided these services to the Committee since 1991. As part of these
services,  Towers  Perrin  advises  the  Committee  on  the  reasonableness   of
compensation paid to executive officers of Informix and how the overall level of
compensation paid to executive officers compares to that paid by other companies
that compete with Informix for executive employees (the "Comparison Companies").

    The  Comparison Companies are a group  of companies in the computer industry
that are either the  source of executive employees  for Informix or which  offer
employment  to candidates from Informix.  The Comparison Companies are generally
headquartered  in  the  same  geographic  area  as  Informix  and  have  similar
international  presences, market capitalizations and  numbers of employees. They
comprise approximately 50% of the companies  shown in the following Hambrecht  &
Quist  Software  Sector Index  shown on  the stock  comparison graph  below. The
Committee believes that the Comparison Companies is the best group for comparing
Informix's compensation  levels because  Informix competes  with this  group  of
companies  for  employees while  the companies  that  comprise the  H&Q Software
Sector Index, the group used for stock performance, are the best for  evaluating
Informix's stock performance because they represent the companies whose products
and services compete with those of Informix.

    Based  upon the advice  that the Committee receives  from Towers Perrin, the
Committee sets the annual compensation (base salary plus incentive compensation)
of and stock option grants  to the CEO. In  addition, the Committee reviews  the
annual  compensation and stock  option grants recommended  by management for all
executive officers, and with the advice of Towers Perrin, approves  compensation
levels and stock option grants.

    The Committee believes that annual compensation and benefit plans need to be
managed  as an investment in Informix's  employees with the expectation that the
employees will contribute to defined levels of financial performance and  return
to  Informix's investors. An  individual's annual compensation  and stock option
grants will vary in relation to the individual's position with Informix and that
person's individual  performance.  The  goal is  to  provide  cash  compensation
targeted at the 50th percentile of that provided by the Comparison Companies for
base  pay and to provide a total  cash compensation through incentive bonuses at
the 75th percentile for superior performance.  The stock option grants given  to
employees  are  intended  to  provide long-term  incentive  compensation  and as
supplemental retirement  benefits for  employees. The  stock grants  are set  at
multiples of base salary

                                       72
<PAGE>
scaling  down  from the  CEO to  non-executive  employees. Grants  are generally
targeted at the  50th percentile of  that provided by  the Comparison  Companies
with grants to superior performing employees targeted at the 75th percentile. In
making  stock grants, the  Committee also considers  the historical and expected
contributions of the employee and previous grants to that employee.

    Other than  a 401K  Plan for  US employees  and as  required by  competitive
practice  or law  in certain  foreign countries  where Informix  has offices and
employees, Informix does not provide retirement benefits for its employees.

    The total  compensation  program  is  designed  to  support  and  complement
Informix's  mission,  management  philosophy, business  strategies  and employee
relations goals; attract and retain  able, skilled and motivated employees;  and
allow  international locations to adapt compensation  plans to local customs and
requirements.

    The CEO  and all  other executive  officers receive  a base  salary that  is
generally  adjusted annually to reflect changes in market conditions, Informix's
performance and individual responsibilities. In addition, the CEO and all  other
executive  officers and certain other key management employees participate in an
annual Executive Incentive  Compensation Plan (the  "EICP"). Bonuses paid  under
the  EICP  are based  on the  officer's  performance and  on the  performance of
Informix as measured by financial objectives established by the Committee at the
beginning of  each  fiscal  year. In  1994  and  again in  1995,  the  corporate
financial  objectives were  and are  operating profit  and revenue  growth, each
rated equally  in  importance. The  financial  objectives are  reviewed  by  the
Committee  each year and those used in a particular year are intended to reflect
those areas most necessary to maximize the return to investors. Depending on the
employee's level, target compensation under the  EICP ranges from 20% to 60%  of
the  employee's  base  salary.  If  Informix's  financial  and  the individual's
personal objectives are exceeded it is possible for the actual bonus amounts  to
exceed  the target amounts. The 1994 and 1995 EICPs have a 300% cap on the bonus
amount that can be paid. Any amount in  excess of 200% is carried over and  paid
in the following year, provided the individual remains an employee of Informix.

    Mr.  White's base salary for 1994 was  determined by review of base salaries
paid to CEO's of the Comparison Companies. Mr. White's base salary for 1994  was
at  the  median  of  the  CEO salaries  of  the  Comparison  Companies  based on
information  available  for  salaries  paid  in  1993.  Mr.  White's  1994  EICP
participation  was based 80% on Informix's  financial performance and 20% on his
personal performance. While Mr. White's target payout was 60% of base salary  at
targeted  levels of performance, his  actual payout was 76%  of base salary as a
result of  Informix achieving  results in  excess of  its financial  performance
objectives in 1994, including the timely release of new products.

    Messrs.  Bergandi and Coulter  participate in the EICP,  but, in addition to
the objectives described  above, a  portion of their  incentive compensation  is
determined  by the results of their respective sales organizations. The EICP and
incentive compensation portion  of the  annual compensation for  the other  four
most  highly compensated officers  was an average  of 70% of  each person's 1994
total base salary.

    During 1994,  the Committee  considered  and granted  stock options  to  the
executive  officers  of  Informix, including  Mr.  White. Each  of  the officers
received grants  based  on his  or  her performance,  level  of  responsibility,
historical  and expected contribution to Informix's success and previous grants.
Mr. White received  a stock option  grant covering 100,000  shares based on  his
senior  position with  Informix, his previous  grants and his  past and expected
contributions to Informix's future success. Each option was granted at the  fair
market  value on the date of grant and will only be of value to the employee if,
and when, the price of Informix's stock exceeds the exercise price of the option
and only if the employee remains with Informix for the entire term of the option
vesting schedule.

                                       73
<PAGE>
    The Committee has been  advised that none  of Informix's executive  officers
will  receive compensation in 1995  that will result in  the loss of a corporate
federal income tax deduction  under I.R.C. Section 162(m).  In the future it  is
the  intention  of  the Committee  to  design compensation  plans  for executive
officers in such a way that the compensation is deductible under I.R.C.  Section
162(m).

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.

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.

                               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 systems  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.

                                       78
<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.

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.

</TABLE>

    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 quarter of
fiscal 1996,  as  license  revenues increased  by  approximately  ten-fold  from
$161,000  for the  first quarter  of fiscal  1995 to  $1.9 million  in the first
quarter of fiscal 1996 due to a $750,000 license fee from a large OEM  customer.
Service  revenues increased by over three-fold from $77,000 in the first quarter
of fiscal 1995 to $307,000, or approximately 14% of total revenues, in the first
quarter of fiscal 1996.

                                       83
<PAGE>
    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.

    COST OF SOFTWARE DISTRIBUTION

    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  11.0%  of  license  revenues,  in  fiscal  1994  to  $160,000, or
approximately 16% of license revenues, in fiscal 1995. From the first quarter of
fiscal 1995 to the first quarter  of fiscal 1996, cost of software  distribution
increased  by  approximately 290%  from $21,000  to $82,000  but decreased  as a
percentage of license revenues from 13% to 4%.

    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  174% from  $227,000 in  the first
quarter of fiscal  1995 to  $623,000 in  the first  quarter of  fiscal 1996  but
decreased as a percentage of service revenues from 295% to 203%.

    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 a distributorship 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 quarter of fiscal 1995 to the first quarter of fiscal 1996, sales
and marketing  expense increased  by approximately  146% from  $845,000 to  $2.1
million but decreased as a percentage of total revenues from 355% to 95%.

    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  57%  from $1.0
million in the first quarter of fiscal 1995 to $1.6 million in the first quarter
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 81% from

                                       84
<PAGE>
$213,000 in the first quarter of fiscal 1995 to $385,000 in the first quarter of
fiscal 1996.  These  increases  resulted primarily  from  growth  in  Illustra's
administrative infrastructure necessary to support expanding operations.

    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  65%  from
$46,000  in the first quarter of fiscal 1995  to $76,000 in the first quarter 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 $16,000 in the first quarter of
1995 to  $29,000  in  the  first  quarter of  1996  due  to  additional  leases.
Additional  leases were required for the new equipment leased for the additional
employees hired by the Company.

</TABLE>

    Since its inception in  1993, Illustra has  funded its operations  primarily
through  private issuance of capital stock  and borrowings under equipment lease
lines ($21.2  million  and $1.3  million,  respectively, through  September  30,
1995).  Cash used in  operating activities was  approximately $1.2 million, $4.7
million, $5.7 million and  $3.1 million in  fiscal 1993, 1994  and 1995 and  the
first  quarter of  fiscal 1996,  respectively. Illustra  used each  of $527,000,
$321,000, $1.3 million and $620,000 in fiscal 1993, 1994 and 1995 and the  first
quarter  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  September 30,  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  September  30,  1995,  Illustra  had  cash,  cash  equivalents  and
investments of $3.3 million and working  capital of $176,000. Illustra does  not
have  a bank  line of  credit, although  it has  equipment lease  lines with two
commercial lenders which  were fully  drawn down as  of September  30, 1995.  In
December  1995,  Illustra  entered  into  a  revolving  credit  arrangement with
Informix under which Illustra  may borrow up to  $5 million for working  capital
requirements. 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

                                       92
<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.

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

                                       94
<PAGE>
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.

                        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

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

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
the earlier of either payment of the license fee or the shipment of the software
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

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.

NOTE 6 -- LEASES
    The Company  leases  certain computer  and  office equipment  under  capital
leases  having terms of three to five years. Amounts capitalized for such leases
are included on the consolidated balance sheets as follows:

</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.

        (INFORMATION AS OF SEPTEMBER 30, 1995 AND FOR THE PERIODS ENDED

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.

    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.

    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.

                         JUNE 30, 1995, 1994, AND 1993
        (INFORMATION AS OF SEPTEMBER 30, 1995 AND FOR THE PERIODS ENDED
                   SEPTEMBER 30, 1995 AND 1994 IS UNAUDITED)

NOTE (1) -- DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES (CONTINUED)
    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 three
months ended September 30,  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

    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. While  legal proceedings  can be  unpredictable,
management  believes the outcome of the matter  will not have a material adverse
effect on  the  Company's  consolidated  results  of  operations  and  financial
position.

    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.

    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.

    The proposed merger 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 in Note 10.

    FINANCING TRANSACTIONS

    In  September  1995,  the   Company  achieved  the  development   milestones
associated  with a put right held by the Series C preferred stockholder (Note 5)
and the put right was terminated  by its terms, whereupon the liquidation  value
was reclassified to stockholders' equity.

    In  November 1995, the Company issued approximately 177,000 shares of Series
D preferred stock for gross proceeds of $531,750.

    In December 1995, Illustra entered into a revolving credit arrangement  with
Informix  under which Illustra may  borrow up to $5  million for working capital
requirements.

           ("SERIES  C PREFERRED")  issued and outstanding  immediately prior to
           the Effective Time (other than any shares of Series C Preferred  that

           upon surrender of the certificate representing such share of Series C

           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,
           including, with respect to each whole share of Parent Common Stock to
           be received, one Right.

       immediately prior to the Effective Time, any shares of Series D Preferred
       to be canceled pursuant to Section  1.6(c) and any Dissenting Shares  (as
       defined  and to the  extent provided in Section  1.7(a)) 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  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
    immediately  prior to the Effective Time  shall be canceled and extinguished
    without any conversion thereof.

       (d)   STOCK OPTIONS.   At  the Effective  Time, all  options to  purchase
       Company  Common Stock  then outstanding  under the  Company's 1992 Equity
    Incentive Plan (the "OPTION PLAN"), or otherwise, shall be assumed by Parent
    in accordance with provisions described below.

           (i) At the Effective Time, each outstanding option to purchase shares
       of Company Common Stock (each a  "COMPANY OPTION") under the Option  Plan
       or  otherwise, whether vested  or unvested, shall  be, in connection with
       the Merger, assumed by Parent. Each  Company Option so assumed by  Parent
       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.

    certificate of  Merger Sub  evidencing ownership  of any  such shares  shall
    continue  to  evidence ownership  of  such shares  of  capital stock  of the

       will be issued,  but in lieu  thereof, each holder  of shares of  Company
    Capital  Stock who would otherwise  be entitled to a  fraction of a share of

    Common  Stock to be  received by such  holder) shall be  entitled to receive
    from Parent an amount of cash (rounded  to the nearest whole cent) equal  to
    the  product of  (i) such fraction,  multiplied by (ii)  the average closing
    price of a share of Parent Common Stock for the five (5) consecutive trading

shall be in proportion to the aggregate number of shares of Parent Common  Stock
which  such holder would otherwise  be entitled to receive  under Section 1.6 by
virtue of ownership of outstanding shares of Company Capital Stock.

    (c)  EXCHANGE PROCEDURES.  Promptly after the Effective Time, the  Surviving
Corporation  shall cause to be mailed to  each holder of record of a certificate

Time  represented outstanding shares of Company  Capital Stock whose shares were

such form and have such other  provisions as Parent may reasonably specify)  and
(ii)  instructions for  use in  effecting the  surrender of  the Certificates in
exchange for  certificates  representing shares  of  Parent Common  Stock.  Upon
surrender  of a Certificate  for cancellation to  the Exchange Agent  or to such
other agent or agents as may be  appointed by Parent, together with such  letter
of  transmittal,  duly completed  and validly  executed  in accordance  with the
instructions thereto,  the  holder of  such  Certificate shall  be  entitled  to
receive  in exchange  therefor a  certificate representing  the number  of whole
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

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>

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,

which with notice or lapse of time, or both, would constitute a default).

technology, know-how, computer software programs or applications (in both source

or  material that are used in the business of the Company as currently conducted
or as  proposed  to be  conducted  by  the Company  (the  "COMPANY  INTELLECTUAL
PROPERTY RIGHTS").

<PAGE>
    (b)  Schedule 2.11(a) sets forth a  complete list of all patents, registered
and material  unregistered trademarks,  registered copyrights,  trade names  and
service   marks,  and  any  applications   therefor,  included  in  the  Company
Intellectual Property Rights, and specifies, where applicable, the jurisdictions
in which  each such  Company  Intellectual Property  Right  has been  issued  or
registered  or in  which an application  for such issuance  and registration has
been filed, including the respective registration or application numbers and the
names of all registered owners. Schedule  2.11(b) sets forth a complete list  of
all  licenses, sublicenses and other agreements to  which the Company is a party
and pursuant to which the Company or  any other person is authorized to use  any
Company  Intellectual Property  Right (excluding  object code  end-user licenses
granted to  end-users in  the ordinary  course of  business that  permit use  of
software  products without a right to  modify, distribute or sublicense the same
("END-USER LICENSES")) or trade secret of the Company, and includes the identity
of all parties  thereto. The  execution and delivery  of this  Agreement by  the
Company,  and  the consummation  of the  transactions contemplated  hereby, will
neither cause the Company to be in violation or default under any such  license,
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
in  and  to  (free  and  clear  of  any  liens  or  encumbrances),  the  Company
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
manufacture,  sale,  licensing or  use of  any  of the  products of  the Company
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
decree,  order, judgment, or stipulation restricting in any manner the licensing
thereof by  the Company.  Each employee  of and  consultant to  the Company  has
executed  a proprietary information  and confidentiality agreement substantially
in the Company's standard forms.

                                  ARTICLE III
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

    Parent and Merger Sub represent and warrant to the Company as follows:

    3.1   ORGANIZATION,  STANDING AND  POWER.    Parent is  a  corporation  duly
organized,  validly existing and in good standing under the laws of the State of
Delaware. Merger Sub is  a corporation duly organized,  validly existing and  in
good standing under the laws of the State of Delaware. Each of Parent and Merger
Sub  has the corporate power to own its  properties and to carry on its business
as now being  conducted and  is duly  qualified to do  business and  is in  good
standing in each jurisdiction in which the failure to be so qualified would have
a  material adverse effect on the ability of Parent and Merger Sub to consummate
the transactions contemplated hereby.

    3.2  AUTHORITY.   Parent and Merger Sub  have all requisite corporate  power
and  authority to enter  into this Agreement and  to consummate the transactions
contemplated hereby.  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 Parent  and Merger Sub.  This
Agreement  has been  duly executed  and delivered by  Parent and  Merger Sub and
constitutes the  valid  and  binding  obligations  of  Parent  and  Merger  Sub,
enforceable in accordance with its terms.

    3.3  CAPITAL STRUCTURE.

    (a)  The authorized stock of Parent consists of 350,000,000 shares of Common
Stock, of which 134,566,906 shares were issued and outstanding as of October 27,
1995, and  5,000,000 shares  of Preferred  Stock,  none of  which is  issued  or
outstanding. The authorized capital stock of Merger Sub consists of 1,000 shares
of  Common Stock, 1,000 shares  of which, as of the  date hereof, are issued and
outstanding and are held by Parent.  All such shares have been duly  authorized,
and  all such issued and outstanding shares  have been validly issued, are fully
paid and nonassessable and are free of any liens or encumbrances other than  any
liens or encumbrances created by or imposed upon the holders thereof.

    (b)  The shares of Parent  Common Stock to be  issued pursuant to the Merger
will be duly authorized, validly issued, fully paid, non-assessable.

    3.4  SEC DOCUMENTS;  PARENT FINANCIAL STATEMENTS.   Parent has furnished  or
made  available  to the  Company  true and  complete  copies of  all  reports or
registration statements  filed  by it  with  the U.S.  Securities  and  Exchange
Commission  (the "SEC") under the Securities Exchange Act of 1934 (the "EXCHANGE
ACT") for all periods subsequent  to January 1, 1993, all  in the form so  filed
(all of the foregoing being collectively referred to as the "SEC DOCUMENTS"). As
of  their respective  filing dates, the  SEC Documents complied  in all material
respects with  the  requirements  of the  Exchange  Act,  and none  of  the  SEC
Documents  contained any untrue statement of a material fact or omitted to state
a material  fact  required  to  be  stated therein  or  necessary  to  make  the
statements  made therein, in light of the circumstances in which they were made,
not misleading, except to the extent corrected by a subsequently filed  document
with  the SEC. The financial statements  of Parent, including the notes thereto,
included in the SEC Documents (the  "PARENT FINANCIAL STATEMENTS") comply as  to
form  in all material respects with  applicable accounting requirements and with
the published rules and regulations of  the SEC with respect thereto, have  been
prepared   in   accordance   with  generally   accepted   accounting  principles
consistently applied  (except as  may be  indicated in  the notes  thereto)  and
present  fairly  the  consolidated financial  position  of Parent  at  the dates
thereof and  of  its  operations and  cash  flows  for the  periods  then  ended
(subject,  in the  case of unaudited  statements, to  normal audit adjustments).
There has been no  change in Parent accounting  policies except as described  in
the notes to the Parent Financial Statements.

    3.5    NO MATERIAL  ADVERSE CHANGE.   Since  the date  of the  balance sheet
included in the Parent's most recently filed  report on Form 10-Q or Form  10-K,
Parent  has conducted  its business  in the  ordinary course  and there  has not
occurred:  (a)  any  material  adverse   change  in  the  financial   condition,

                                      A-20
<PAGE>
liabilities,  assets or business of  Parent; (b) any amendment  or change in the
Certificate of  Incorporation  or  Bylaws  of Parent;  or  (c)  any  damage  to,
destruction  or loss  of any assets  of the  Parent, (whether or  not covered by
insurance) that  materially and  adversely affects  the financial  condition  or
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.

                                   ARTICLE IV

usual,  regular  and  ordinary  course  in  substantially  the  same  manner  as
heretofore  conducted, to pay  its debts and  Taxes when due,  to pay or perform

preserve  intact its present business  organization, keep available the services
of its present officers and key employees and preserve their relationships  with
customers,  suppliers,  distributors,  licensors, licensees,  and  others having
business dealings  with it,  all  with the  goal  of preserving  unimpaired  its
goodwill  and  ongoing  businesses  at the  Effective  Time.  The  Company shall
promptly notify Parent of any materially  negative event related to the  Company
or its business. Except as expressly contemplated by this Agreement or disclosed

    (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

Statement as soon  as is reasonably  practicable following preparation  thereof.
The  Company shall provide to Parent and  its counsel for inclusion in the Proxy

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

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

<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.

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.

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

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.

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

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.

    5.13   FORM S-8.  Parent shall file a registration statement on Form S-8 for
the shares  of Parent  Common Stock  issuable with  respect to  assumed  Company

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.

    effect as if  made on  and as  of the Effective  Time, except,  in all  such

    30,   1995.  For  purposes  of  this   condition,  none  of  the  following,
    individually or  in the  aggregate, shall  be deemed  to constitute  such  a

    Merger.

                                  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.

                                   ARTICLE IX

    9.4    ENTIRE  AGREEMENT; ASSIGNMENT.    This Agreement,  the  schedules and
Exhibits hereto, and the  documents and instruments  and other agreements  among

otherwise have to such jurisdiction and such process.

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

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

        (d)  The dissenting  stockholder, with  the consent  of the corporation,

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.

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.

                                      II-2

    (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 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.

                    ILLUSTRA INFORMATION TECHNOLOGIES, INC.
                                VOTING AGREEMENT

    This  Voting Agreement ("Agreement") is made and entered into as of December
20, 1995, between Informix Corporation,  a Delaware corporation ("Parent"),  and
the    undersigned   stockholder   ("Stockholder")   of   Illustra   Information
Technologies, Inc., a Delaware corporation ("Company").

                                    RECITALS

    A.  Concurrently with the execution  of this Agreement, Parent, Company  and
Informix Delaware, Inc., a Delaware corporation and a wholly owned subsidiary of
Parent ("Merger Sub"), have entered into an Agreement and Plan of Reorganization
(the  "Merger Agreement") which provides for the merger (the "Merger") of Merger
Sub with and into the Company. Pursuant  to the Merger, shares of capital  stock
of  the  Company will  be converted  into Common  Stock of  Parent on  the basis
described in the Merger Agreement.

    B.  The Stockholder is the record holder and beneficial owner (as defined in
Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the  "Exchange
Act"))  of such number of shares of  the outstanding Common Stock of the Company
as is indicated on the final page of this Agreement (the "Shares").

    C.  Parent desires the Stockholder to agree, and the Stockholder is  willing
to  agree, not  to transfer or  otherwise dispose of  any of the  Shares, or any
other shares of capital stock of the Company acquired hereafter and prior to the
Expiration Date (as defined in Section 1.1 below, except as otherwise  permitted
hereby),  and to vote the  Shares and any other such  shares of capital stock of
the Company so as to facilitate consummation of the Merger.

    NOW, THEREFORE, intending to be legally bound, the parties agree as follows:

    1.  AGREEMENT TO RETAIN SHARES.

    1.1  TRANSFER AND ENCUMBRANCE.   Stockholder agrees not to transfer  (except
as  may  be specifically  required by  court order),  sell, exchange,  pledge or
otherwise dispose of or encumber any of the Shares or any New Shares as  defined
in Section 1.2 below, or to make any offer or agreement relating thereto, at any
time  prior to the Expiration  Date. As used herein,  the term "Expiration Date"
shall mean the earlier to  occur of (i) such date  and time as the Merger  shall
become  effective  in accordance  with the  terms and  provisions of  the Merger
Agreement and  (ii)  such  date  and  time as  the  Merger  Agreement  shall  be
terminated pursuant to Article VIII thereof.

    1.2   ADDITIONAL PURCHASES.   Stockholder agrees that  any shares of capital
stock of  the  Company that  Stockholder  purchases  or with  respect  to  which
Stockholder  otherwise acquires beneficial ownership after the execution of this
Agreement and prior to  the Expiration Date ("New  Shares") shall be subject  to
the  terms  and conditions  of  this Agreement  to the  same  extent as  if they
constituted Shares.

    2.  AGREEMENT TO VOTE SHARES.   At every meeting of the stockholders of  the
Company  called with respect to  any of the following,  and at every adjournment
thereof, and on every action or approval by written consent of the  stockholders
of  the Company with respect to any of the following, Stockholder shall vote the
Shares and any New Shares: (i) in favor of approval of the Merger Agreement  and
the  Merger and any matter  that could reasonably be  expected to facilitate the
Merger (including without limitation the  conversion of any shares of  Preferred
Stock of the Company into Common Stock of the Company immediately prior to or at
the  effective  time  of  the  Merger, consistent  with  the  provisions  of the
Company's Certificate of  Incorporation and with  the requirements necessary  to
account  for the Merger as a  "pooling-of-interests"); and (ii) against approval
of any proposal made  in opposition to or  competition with consummation of  the
Merger  and against any merger, consolidation, sale of assets, reorganization or
recapitalization, with any party other than  with Parent and its affiliates  and
against  any liquidation or winding up of  the Company (each of the foregoing is
hereinafter referred to as  an "Opposing Proposal").  Stockholder agrees not  to
take any actions contrary to Stockholder's obligations under this Agreement.
<PAGE>
    3.   IRREVOCABLE PROXY.  Concurrently  with the execution of this Agreement,
Stockholder agrees to deliver to Parent a  proxy in the form attached hereto  as
Exhibit  A (the "Proxy"), which  shall be irrevocable, with  the total number of
shares of  capital stock  of the  Company beneficially  owned (as  such term  is
defined in Rule 13d-3 under the Exchange Act) by Stockholder set forth therein.

    4.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
STOCKHOLDER.  Stockholder hereby represents, warrants and covenants to Parent as
follows:

    4.1   OWNERSHIP OF SHARES.   Stockholder (i) is  the beneficial owner of the
Shares, which at the date hereof and  at all times up until the Expiration  Date
will  be  free  and  clear  of any  liens,  claims,  options,  charges  or other
encumbrances; (ii) does not beneficially own any shares of capital stock of  the
Company  other  than  the  Shares  (excluding  shares  as  to  which Stockholder
currently disclaims beneficial ownership in accordance with applicable law); and
(iii) has full power and authority to  make, enter into and carry out the  terms
of this Agreement and the Proxy.

    4.2   NO PROXY SOLICITATIONS.  Stockholder will not, and will not permit any
entity  under  Stockholder's  control  to:  (i)  solicit  proxies  or  become  a
"participant"  in a "solicitation" (as such  terms are defined in Regulation 14A
under the  Exchange Act)  with  respect to  an  Opposing Proposal  or  otherwise
encourage  or  assist any  party in  taking  or planning  any action  that would
compete with,  restrain or  otherwise serve  to interfere  with or  inhibit  the
timely  consummation of the  Merger in accordance  with the terms  of the Merger
Agreement; (ii)  initiate a  stockholders'  vote or  action  by consent  of  the
Company  stockholders with  respect to an  Opposing Proposal; or  (iii) become a
member of a "group" (as such term is used in Section 13(d) of the Exchange  Act)
with respect to any voting securities of the Company with respect to an Opposing
Proposal.

    5.    ADDITIONAL  DOCUMENTS.   Stockholder  hereby covenants  and  agrees to
execute and  deliver any  additional documents  necessary or  desirable, in  the
reasonable  opinion of Parent or  Stockholder, as the case  may be, to carry out
the intent of this Agreement.

    6.  CONSENT AND  WAIVER.  Stockholder hereby  gives any consents or  waivers
that  are reasonably required for the consummation of the Merger under the terms

                               IRREVOCABLE PROXY

    The  undersigned stockholder  of Illustra Information  Technologies, Inc., a
Delaware corporation ("Company"), hereby  irrevocably appoints the directors  on
the   Board  of  Directors  of  Informix  Corporation,  a  Delaware  corporation
("Parent"), and each of them, as the sole and exclusive attorneys and proxies of
the undersigned, with full power of substitution and resubstitution, to the full
extent of the undersigned's rights with  respect to the shares of capital  stock
of the Company beneficially owned by the undersigned, which shares are listed on
the  final page of  this Proxy (the "Shares"),  and any and  all other shares or
securities issued or issuable  in respect thereof on  or after the date  hereof,
until  such time as that certain Agreement  of Merger and Plan of Reorganization
dated as of December 20, 1995  (the "Merger Agreement"), among Parent,  Informix
Delaware,  Inc., a Delaware corporation and  a wholly-owned subsidiary of Parent
("Merger Sub"), and Company, shall be terminated in accordance with its terms or
the Merger (as defined in the Merger Agreement) is effective. Upon the execution
hereof, all prior proxies  given by the undersigned  with respect to the  Shares
and any and all other shares or securities issued or issuable in respect thereof
on or after the date hereof are hereby revoked and no subsequent proxies will be

immediately prior to or at the effective time of the Merger, consistent with the
provisions  of  the  Company's  Certificate   of  Incorporation  and  with   the
requirements  necessary to account for  the Merger as a "pooling-of-interests"),

Company.

    The attorneys and proxies named above  may only exercise this proxy to  vote

Agreement at every annual, special or  adjourned meeting of the stockholders  of
Company  and  in every  written consent  in lieu  of such  meeting, in  favor of

    RE: REGISTRATION STATEMENT ON FORM S-4

Ladies and Gentlemen:

    We  have examined  the Registration Statement  on Form  S-4, Commission File
Number 33-          , filed by you with  the Securities and Exchange  Commission
(the  "Commission")  on  January  10, 1996  (the  "Registration  Statement"), in
connection with the registration under the  Securities Act of 1933, as  amended,
of  15,000,000 shares of  your Common Stock  (the "Shares"). As  your counsel in
connection with this transaction, we have examined the proceedings taken and are
familiar with the proceedings proposed to be taken by you in connection with the
sales and issuance of the Shares.

    It is our  opinion that upon  conclusion of the  proceedings being taken  or
contemplated  by us, as your  counsel, to be taken prior  to the issuance of the
Shares, and upon completion  of the proceedings being  taken in order to  permit
such  transactions to be carried  out in accordance with  the securities laws of
the various  states where  required, the  Shares, when  issued and  sold in  the
manner  described in  the Registration  Statement, will  be legally  and validly
issued, fully paid and non-assessable.

    We consent to  the use of  this opinion  as an exhibit  to the  Registration
Statement,  and further consent to the use of our name wherever appearing in the
Registration Statement, including the proxy statement/prospectus constituting  a
part thereof, and any amendment thereto.

                                          Very truly yours,

                         FULL RECOURSE INSTALLMENT NOTE

Menlo Park, California, June 15, 1993.

    For  value received,  MYRON (MIKE)  SARANGA ("Saranga")  promises to  pay to
INFORMIX SOFTWARE, INC. ("Holder"), at such place as the Holder may from time to
time direct, the sum of ONE  HUNDRED FIFTY THOUSAND DOLLARS ($150,000.00),  with
interest in arrears on the unpaid balance from the date of this Note at the rate
of  Three and  Fifty-Six/100 Percent (3.56%)  per annum,  principal and interest
payable in lawful money of the United  States. The principal shall be paid in  a
single  payment  on the  earlier of  June 2,  1995; the  date Saranga  sells his
Connecticut property; or the date  Saranga's employment with Informix  Software,
Inc.  terminates and Interest shall be paid monthly commencing July 15, 1993 and
continuing on the  same day  of each successive  month thereafter  with a  final
payment of all unpaid interest at the time of payment of the principal.

    Each  payment shall  be credited  first to  interest then  due, and  then to
reduce the outstanding principal. Should default  be made in the payment of  any
installment  of principal or interest when due, then, or at any time during such
default, the  entire amount  of  unpaid principal  and  interest shall,  at  the
election  of  the Holder,  become immediately  due  and payable  without notice.
Should Saranga's employment with Holder be  terminated by holder or by  Saranga,
for  any reason, including death or disability,  with or without cause, then, or
at any time following  such termination, the entire  amount of unpaid  principal
and  interest shall, at the  election of the Holder,  become immediately due and
payable without notice.  This Note  shall not restrict  the right  of Holder  to
terminate  the employment  of Saranga at  any time  and for any  reason, with or
without cause; and Saranga  expressly waives any right  to a term of  employment
for  any period of time.  If suit be brought on  this Note, the prevailing party
promises to pay the other party's cost of suit and such sum as the Court may fix
as attorneys' fees.

    It is understood that this Note will be secured by a Second Deed of Trust on
real property to be acquired by Saranga in the State of California.
