                  FIRST AMENDED AND RESTATED RIGHTS AGREEMENT

                                April 26, 2002


         This AMENDMENT NO. 2 ("Amendment No. 2") is being entered into as of
the date first written above, between Ascential Software Corporation (formerly
known as Informix Corporation), a Delaware corporation (the "Company"), and
EquiServe Trust Company, N.A., a national banking association, as Rights Agent
("EquiServe"). Capitalized terms used but not defined herein shall have the
meanings ascribed to such terms in the Rights Agreement.

         WHEREAS, the Company is a party to, and EquiServe is a successor in
interest to the Rights Agent under, the First Amended and Restated Rights
Agreement, dated as of August 12, 1997, between Informix Corporation and
BankBoston, N.A, as Rights Agent, as amended by an Amendment to the Informix
Corporation First Amended and Restated Rights Agreement ("Amendment No. 1"),
dated as of November 17, 1997 (the "Rights Agreement");

         WHEREAS, pursuant to Section 27 of the Rights Agreement, prior to the
Distribution Date the Company may supplement or amend the Rights Agreement
without the approval of any of the holders of Rights; and

         WHEREAS, the Company now desires to amend the Rights Agreement and to
update certain information therein, as set forth in this Amendment No. 2, and
deems such amendments and updates to be necessary and desirable.

         NOW THEREFORE, in consideration of the premises and mutual agreements
set forth herein, the Parties hereby agree as follows:

1.   The title of the Rights Agreement shall be changed to: The Ascential
     Software Corporation First Amended and Restated Rights Agreement.

2.   All references in the Rights Agreement to "Informix Corporation" shall be
     replaced with "Ascential Software Corporation."

3.   All references in the Rights Agreement to "BankBoston, N.A." as the shall
     be replaced with "EquiServe Trust Company, N.A."

4.   The Definition of "Acquiring Person" set forth in Section 1(a) of the
     Rights Agreement is hereby amended in its entirety to read as follows:

               "Acquiring Person" shall mean any Person who or which, together
          with all Affiliates and Associates of such Person, shall be the
          Beneficial Owner of 20% or more of the Common Shares then
          outstanding, but shall not include (i) the Company, (ii) any
          Subsidiary of the Company, or (iii) any employee benefit plan of the
          Company or of any Subsidiary of the Company, or any entity holding
          Common Shares for or pursuant to the terms of any such plan.
          Notwithstanding the foregoing, no Person shall be deemed to be an
          "Acquiring Person" as the result of an acquisition of Common Shares
          by the Company which, by reducing the number of shares outstanding,
          increases the proportionate number of shares beneficially owned by
          such Person to 20% or more of the Common Shares of the Company then
          outstanding; provided however, that if a Person shall become the
          Beneficial Owner of 20% or more of the Common Shares of the Company
          then outstanding by reason of share purchases by the Company and
          shall, after such share purchases by the Company, become the
          Beneficial Owner of any additional Common Shares of the Company,
          then such Person shall be deemed to be an "Acquiring Person."

5.   Section 11(a)(iv) of the Rights Agreement is hereby amended in its
     entirety to read as follows:

               In the event that the number of Common Shares which are
          authorized by the Company's Certificate of Incorporation but not
          outstanding or reserved for issuance for purposes other than upon
          exercise of the Rights are not sufficient to permit the exercised in
          full of the Rights the Company shall: (A) determine the excess of
          (1) the value of the Common Shares issuable upon the exercise of a
          Right (the "Current Value") over (2) the Purchase Price (such
          excess, the "Spread") and (B) with respect to each such Right, make
          adequate provision to substitute for such Common Shares, upon
          exercise of the Rights (1) cash, (2) a reduction in the Purchase
          Price, (3) other equity securities of the Company (including,
          without limitation, shares or units of shares of any series of
          preferred stock which the Board of Directors of the Company has
          deemed to have the same value as Common Shares (such shares or units
          of shares of preferred stock are herein called "common stock
          equivalents"), (5) other assets or (6) any combination of the
          foregoing, having an aggregate value equal to the Current Value,
          where such aggregate value has been determined by the Board of
          Directors of the Company based on the advice of a nationally
          recognized investment banking firm selected by the Board of
          Directors of the Company; provided however, if the Company shall not
          have made adequate provision to deliver value pursuant to clause (B)
          above within thirty (30) days following the later of (x) the first
          occurrence of a Triggering Event and (y) the date on which the
          Company's right of redemption pursuant to Section 23(a) expires (the
          later of (x) and (y) being referred to herein as the "Section
          11(a)(ii) Trigger Date"), then the Company shall be obligated to
          deliver, upon the surrender for exercise of a Right and without
          requiring payment of the Purchase Price, Common Shares (to the
          extent available), and then, if necessary, cash, which shares and/or
          cash have an aggregate value equal to the Spread. If the Board of
          Directors of the Company shall determine in good faith that it is
          likely that sufficient additional Common Shares could be authorized
          for issuance upon exercise in full of the Rights, the thirty (30)
          day period set forth above may be extended to the extent necessary,
          but not more than ninety (90) days after the Section 11(a)(ii)
          Trigger Date, in order that the Company may seek stockholder
          approval for the authorization of such additional shares (such
          thirty (30) day period, as it may be extended, the "Substitution
          Period"). To the extent that the Company determines that some action
          need be taken pursuant to the first and/or second sentences of this
          Section 11(a)(iv), the Company (x) shall provide, subject to Section
          7(e) hereof, that such action shall apply uniformly to all
          outstanding Rights and (y) may suspend the exercisability of the
          Rights until the expiration of the Substitution Period in order to
          seek any authorization of additional shares and/or to decide the
          appropriate form of distribution to be made pursuant to such first
          sentence and to determine the value thereof. In the event of any
          such suspension, the Company shall issue a public announcement
          stating that the exercisability of the Rights has been temporarily
          suspended, as well as a public announcement at such time as the
          suspension is no longer in effect. For purposes of this Section
          11(a)(iv), the value of the Common Shares shall be the current per
          share market price (as determined pursuant to Section 11(d) hereof)
          of the Common Shares on the Section 11(a)(ii) Trigger Date and the
          value of any "common stock equivalent" shall be deemed to have the
          same value as the Common Shares on such date.

6.   Section 26 of the Rights Agreement is hereby amended in its entirety to
     read as follows:

          Section 26. Notices. Notices or demands authorized by this
          Agreement to be given or made by the Rights Agent or by the holder

     Agreement, is hereby amended in its entirety to read as set forth in

                              Rights Certificate

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


         This certifies that _____________, or registered assigns, is the
registered owner of the number of Rights set forth above, each of which
entitles the owner thereof, subject to the terms, provisions and conditions of
the First Amended and Restated Rights Agreement, as amended (the "Rights
Agreement") to purchase from Ascential Software Corporation (the "Company") at
any time after the Distribution Date (as such term is defined in the Rights
Agreement) and prior to 5:00 p.m., Boston time, on July 25, 2005, at the

such purpose, or at the office of its successor as Rights Agent, one fully
paid and nonassessable share of Common Stock, par value $.0l per share, (the
"Common Shares"), of the Company, at a purchase price of $60.00 per Common
Share (the "Purchase Price"), upon presentation and surrender of this Rights
Certificate with the Form of Election to Purchase and related Certificate duly
executed. The number of Rights evidenced by this Rights Certificate (and the
number of Common Shares which may be purchased upon exercise hereof) set forth
above are the number and Purchase Price as of August 12, 1997, based on the
Common Shares as constituted at such date. As provided in the Rights
Agreement, the Purchase Price and the number and kind of Common Shares or
other securities which may be purchased upon the exercise of the Rights
evidenced by this Rights Certificate are subject to modification and
adjustment upon the happening of certain events.

         This Rights Certificate is subject to all of the terms, provisions
and conditions of the Rights Agreement, which terms, provisions and conditions
are hereby incorporated by reference and made a part hereof. Reference is made
