ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     The Indiana Business Corporation Law provides that a corporation, unless
limited by its articles of incorporation, is required to indemnify its directors
and officers against reasonable expenses incurred in the successful defense of
any proceeding arising out of their serving as a director or officer of the
corporation.

     As permitted by the Indiana Business Corporation Law, the Registrant's
Restated Articles of Incorporation provide for indemnification of directors,
officers, employees and agents of the Registrant against any and all liability
and reasonable expense that may be incurred by them, arising out of any claim or
action, civil, criminal, administrative or investigative, in which they may
become involved by reason of being or having been a director, officer, employee
or agent. To be entitled to indemnification, those persons must have been wholly
successful in the claim or action or the board of directors must have
determined, based upon a written finding of legal counsel or another independent
referee, or a court of competent jurisdiction must have determined, that such
persons acted in good faith in what they reasonably believed to be the best
interest of the Registrant (or at least not opposed to its best interests) and,
in addition, in any criminal action, had reasonable cause to believe their
conduct was lawful (or had no reasonable cause to believe that their conduct was
unlawful). The Restated Articles of Incorporation authorize the Registrant to
advance funds for expenses to an indemnified person, but only upon receipt of an
undertaking that he or she will repay the same if it is ultimately determined
that such party is not entitled to indemnification.

     The Registrant also has an Indemnity Agreement with each of its directors
and executive officers. The standard for indemnification under the Indemnity
Agreement is substantially the same as under the Registrant's Restated Articles
of Incorporation. The Indemnity Agreement, however, provides for mandatory
advancement of expenses if the indemnitee provides the Registrant with a written
affirmation of the indemnitee's good faith belief that he or she is entitled to
indemnification and a written undertaking to repay the advance if it is
ultimately determined that the indemnitee is not entitled to indemnification.
The undertaking need not be secured. The Indemnity Agreement also provides for
mandatory advancement of expenses in derivative actions on behalf of the
Registrant against an indemnitee.

     The rights of indemnification provided by the Restated Articles of
Incorporation and the Indemnity Agreements are not exhaustive and are in
addition to any rights to which a director or officer may otherwise be entitled
by contract or as a matter of law. Irrespective of the provisions of the
Restated Articles of Incorporation and the Indemnity Agreements, the Registrant
may, at any time and from time to time, indemnify directors, officers, employees
and other persons to the full extent permitted by the provisions of applicable
law at the time in effect, whether on account of past or future transactions.

     In addition, the Registrant has a directors' and officers' liability and
company reimbursement policy that insures against certain liabilities under the
Securities Act, subject to applicable retentions.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

          Not Applicable.

ITEM 8.  EXHIBITS.

     The list of Exhibits is incorporated herein by reference to the Index
to Exhibits.

   The Registrant hereby undertakes that it will submit or has submitted the
Plan and any amendment thereto to the Internal Revenue Service ("IRS") in a
timely manner and has made or will make all changes required by the IRS in
order to qualify the Plan under Section 401 of the Internal Revenue Code.

ITEM 9. UNDERTAKINGS.

          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;

               (ii) To reflect in the prospectus any facts or events arising
                    after the effective date of the 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 the registration
                    statement;

               (iii) To include any material information with respect to the
                    plan of distribution not previously disclosed in the
                    registration statement or any material change to such
                    information in the registration statement;

               Provided, however, that paragraphs (1)(i) and (1)(ii) do not
               apply if the information required to be included in a
               post-effective amendment by those paragraphs is contained in
               periodic reports filed with or furnished to the Commission by the
               Registrant pursuant to Section 13 or Section 15(d) of the
               Securities Exchange Act of 1934 that are incorporated by
               reference in the registration statement.

          (2)  That, for the purpose 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 the time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered which remain
               unsold at the termination of the offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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.

     Insofar as 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.

     The following documents heretofore filed by Interactive Intelligence, Inc.

     (1)  The Registrant's Annual Report on Form 10-K for the fiscal year ended

     (2)  The description of the Registrant's Common Stock contained in the

          Securities and Exchange Commission on September 17, 1999, including

          description.

     In addition, all documents subsequently filed by the Registrant or the
Interactive Intelligence, Inc. 401(k) Savings Plan (the "Plan") pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act prior to the filing of a
post-effective amendment which indicates that all securities offered hereby have
been sold or which deregisters all securities offered hereby then remaining

Statement and to be a part hereof from their respective dates of filing.

     The Registrant will promptly provide without charge to each person to whom
a prospectus is delivered a copy of any or all information that has been
incorporated herein by reference (not including exhibits to the information that

by reference into such information) upon the written or oral request of such
person directed to the Secretary of the Registrant at its principal offices,
8909 Purdue Road, Suite 300, Indianapolis, Indiana 46268, telephone (317)
872-3000.

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not Applicable.
ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     The Indiana Business Corporation Law provides that a corporation, unless
limited by its articles of incorporation, is required to indemnify its directors
and officers against reasonable expenses incurred in the successful defense of
any proceeding arising out of their serving as a director or officer of the
corporation.

     As permitted by the Indiana Business Corporation Law, the Registrant's
Restated Articles of Incorporation provide for indemnification of directors,
officers, employees and agents of the Registrant against any and all liability
and reasonable expense that may be incurred by them, arising out of any claim or
action, civil, criminal, administrative or investigative, in which they may
become involved by reason of being or having been a director, officer, employee
or agent. To be entitled to indemnification, those persons must have been wholly
successful in the claim or action or the board of directors must have
determined, based upon a written finding of legal counsel or another independent
referee, or a court of competent jurisdiction must have determined, that such
persons acted in good faith in what they reasonably believed to be the best
interest of the Registrant (or at least not opposed to its best interests) and,
in addition, in any criminal action, had reasonable cause to believe their
conduct was lawful (or had no reasonable cause to believe that their conduct was
unlawful). The Restated Articles of Incorporation authorize the Registrant to
advance funds for expenses to an indemnified person, but only upon receipt of an
undertaking that he or she will repay the same if it is ultimately determined
that such party is not entitled to indemnification.

     The Registrant also has an Indemnity Agreement with each of its directors
and executive officers. The standard for indemnification under the Indemnity
Agreement is substantially the same as under the Registrant's Restated Articles
of Incorporation. The Indemnity Agreement, however, provides for mandatory
advancement of expenses if the indemnitee provides the Registrant with a written
affirmation of the indemnitee's good faith belief that he or she is entitled to
indemnification and a written undertaking to repay the advance if it is
ultimately determined that the indemnitee is not entitled to indemnification.
The undertaking need not be secured. The Indemnity Agreement also provides for
mandatory advancement of expenses in derivative actions on behalf of the
Registrant against an indemnitee.

     The rights of indemnification provided by the Restated Articles of
Incorporation and the Indemnity Agreements are not exhaustive and are in
addition to any rights to which a director or officer may otherwise be entitled
by contract or as a matter of law. Irrespective of the provisions of the
Restated Articles of Incorporation and the Indemnity Agreements, the Registrant
may, at any time and from time to time, indemnify directors, officers, employees
and other persons to the full extent permitted by the provisions of applicable
law at the time in effect, whether on account of past or future transactions.

     In addition, the Registrant has a directors' and officers' liability and
company reimbursement policy that insures against certain liabilities under the
Securities Act, subject to applicable retentions.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

          Not Applicable.

ITEM 8.  EXHIBITS.

     The list of Exhibits is incorporated herein by reference to the Index
to Exhibits.

   The Registrant hereby undertakes that it will submit or has submitted the
Plan and any amendment thereto to the Internal Revenue Service ("IRS") in a
timely manner and has made or will make all changes required by the IRS in
order to qualify the Plan under Section 401 of the Internal Revenue Code.

                                      -2-
ITEM 9. UNDERTAKINGS.

          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;

               (ii) To reflect in the prospectus any facts or events arising
                    after the effective date of the 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 the registration
                    statement;

               (iii) To include any material information with respect to the
                    plan of distribution not previously disclosed in the
                    registration statement or any material change to such
                    information in the registration statement;

               Provided, however, that paragraphs (1)(i) and (1)(ii) do not
               apply if the information required to be included in a
               post-effective amendment by those paragraphs is contained in
               periodic reports filed with or furnished to the Commission by the
               Registrant pursuant to Section 13 or Section 15(d) of the
               Securities Exchange Act of 1934 that are incorporated by
               reference in the registration statement.

          (2)  That, for the purpose 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 the time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered which remain
               unsold at the termination of the offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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.

     Insofar as 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.

                                      -3-
