               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference

     FileNet  Corporation (the  "Registrant")  hereby  incorporates by reference
into this Registration  Statement the following documents  previously filed with
the Securities and Exchange Commission (the "SEC"):

     (a)  The Registrant's  Annual Report on Form 10-K for the fiscal year ended
          December 31, 1996, filed with the SEC on April 4, 1997;

     (b)  The Registrant's  Quarterly Report on Form 10-Q for the quarters ended
          June 30, 1997, and March 31, 1997,  filed  with the SEC on August 145,
          1997, and May 15, 1997, respectively; and

     (c)  The Registrant's  Registration Statement No. 0-15997 on Form 8-A filed
          with the SEC on June 24,  1987, in which there is described the terms,
          rights and provisions applicable to the Registrant's Common Stock.


     All reports and definitive  proxy or information  statements filed pursuant
to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 (the
"1934  Act")  after  the date of this  Registration  Statement  and prior to the
filing of a post-effective amendment which indicates that all securities offered
hereby have been sold or which  deregisters all securities then remaining unsold
shall be deemed to be incorporated by reference into this Registration Statement
and to be a part hereof from the date of filing of such documents. Any statement
contained in a document  incorporated  or deemed to be incorporated by reference
herein  shall be  deemed to be  modified  or  superseded  for  purposes  of this
Registration Statement to the extent that a statement contained herein or in any
subsequently filed document which also is deemed to be incorporated by reference
herein modifies or supersedes such statement.  Any such statement so modified or
superseded  shall  not be  deemed,  except  as so  modified  or  superseded,  to
constitute a part of this Registration Statement.


Item 4.  Description of Securities

     Not applicable.


Item 5.  Interests of Named Experts and Counsel

     Not applicable.


Item 6.  Indemnification of Directors and Officers

     Pursuant to the provisions of Section 145 of the General Corporation Law of
Delaware,  the Registrant as a Delaware  corporation  has power to indemnify any
person  who  was or is a  party  or is  threatened  to be  made a  party  to any
threatened,  pending or  completed  action,  suit or  proceeding  (other than an
action  by or in the right of the  Registrant)  by reason of the fact that he or
she is or was a director, officer, employee or agent of the Registrant or of any
corporation,  partnership, joint venture, trust or other enterprise for which he
or she is or was  serving in such  capacity  at the  request of the  Registrant,
against any and all  expenses,  judgments,  fines and amounts paid in settlement
which were  reasonably  incurred by him or her in  connection  with such action,
suit or proceeding. The power to indemnify applies only if such person acted in



good  faith  and in a manner  he or she  reasonably  believed  to be in the best
interests,  or not opposed to the best  interests,  of the Registrant  and, with
respect to any criminal  action or  proceeding,  if he or she had no  reasonable
cause to believe his or her conduct was unlawful.

     The power to indemnify  also applies to actions  brought by or in the right
of the Registrant, but only to the extent of defense and settlement expenses and
not to any satisfaction of a judgment or settlement of the claim itself. In such
actions,  however, no indemnification  will be made if there is any adjudication
of negligence or misconduct,  unless the court, in its discretion, feels that in
the light of all the circumstances indemnification should apply.

     To the extent any such person is  successful  in the defense of the actions
referred  to above,  such  person is  entitled  pursuant  to Section  145 of the
General  Corporation  Law of Delaware to  indemnification  as  described  above.
Section 145 also grants power to advance litigation  expenses upon receipt of an
undertaking to repay such advances in the event no right to  indemnification  is
subsequently  shown.  The Registrant may also obtain insurance at its expense to
protect  anyone  who  might  be  indemnified,  or  has  a  right  to  insist  on
indemnification, under the statute.

Item 9.  Undertakings

     A. The undersigned  Registrant hereby  undertakes:  (1) to file, during any
period in which  offers or sales are being made, a  post-effective  amendment to
this  Registration  Statement (i) to include any prospectus  required by Section
10(a)(3) of the  Securities  Act of 1933,  as amended (the "1933 Act"),  (ii) to
reflect in the  prospectus  any facts or events arising after the effective date
of this  Registration  Statement  (or the most recent  post-effective  amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the  information  set  forth in this  Registration  Statement,  and  (iii) to
include any material  information  with respect to the plan of distribution  not
previously  disclosed in this  Registration  Statement or any material change to
such information in this Registration Statement; provided, however, that clauses
(1)(i) and (1)(ii) shall not apply if the information required to be included in
a post-effective  amendment by those paragraphs is contained in periodic reports
filed by the Registrant  pursuant to Section 13 or Section 15(d) of the 1934 Act
that are incorporated by reference into this  Registration  Statement;  (2) that
for the  purpose of  determining  any  liability  under the 1933 Act,  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;  and
(3) to remove from  registration by means of a  post-effective  amendment any of
the securities  being registered which remain unsold upon the termination of the
Registrant's  1995  Stock  Option  Plan or the  1988  Employee  Qualified  Stock
Purchase Plan or upon the  expiration of the Option Grant made to Mr. Roberts or
the Option Grant made to Mr. Ercanbrack.

     B. The  undersigned  Registrant  hereby  undertakes  that,  for purposes of
determining  any liability  under the 1933 Act, each filing of the  Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference into this Registration Statement 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.

     C. Insofar as  indemnification  for liabilities  arising under the 1933 Act
may be permitted to directors, officers or controlling persons of the Registrant
pursuant to the indemnity  provisions  summarized  in Item 6 or  otherwise,  the
Registrant has been informed that in the opinion of the SEC such indemnification
is  against  public  policy  as  expressed  in the 1933  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  1933  Act  and  will  be  governed  by the  final
adjudication of such issue.
