               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         The following documents heretofore filed (File Number 0-27975) with the
Securities and Exchange Commission (the "Commission") by eLoyalty Corporation
(the "Company") are incorporated herein by reference:

         (a) The Information Statement/Prospectus dated February 8, 2000 and
contained in the Registration Statement on Form S-1 filed by the Company with
the Commission (Registration No. 333-94293); and

         (b) The description of the Common Stock, $.01 par value, of the Company
(the "Common Stock") and the description of the Preferred Stock Purchase Rights
of the Company (the "Rights") associated with the Common Stock, contained in the
Registration Statement on Form 8-A filed by the Company with the Commission on
January 20, 2000, including any amendments or reports filed for the purpose of
updating such descriptions.

         All documents filed by the Company pursuant to Sections 13(a), 13(c),
14 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
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, are
deemed to be incorporated by reference into this Registration Statement and to
be a part hereof from the respective dates of filing of such documents (such
documents, and the documents enumerated above, being hereinafter referred to as
"Incorporated Documents").

         Any statement contained in an Incorporated Document 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be modified or superseded for purposes of this Registration Statement to the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 other subsequently filed
Incorporated Document 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so modified or superseded shall not be deemed, except as so modified or
superseded, to constitute a part of this Registration Statement.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

         Section 145 of the Delaware General Corporation Law ("DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of such corporation), by


                                       2
<PAGE>   3
reason of the fact that such person was an officer or director of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that such officer or
director acted in good faith and in a manner he reasonably believed to be in or
not opposed to the corporation's best interests, and, for criminal proceedings,
had no reasonable cause to believe his conduct was illegal. A Delaware
corporation may indemnify officers and directors in an action by or in the right
of the corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the corporation in the performance of his duty. Where an officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses which
such officer or director actually and reasonably incurred.

         The Company's bylaws provide that it will indemnify its directors and
officers to the fullest extent permitted by Delaware law, except that no
indemnification will be provided to a director, officer, employee or agent if
the indemnification sought is in connection with a proceeding initiated by such
person without the authorization of the board of directors. The bylaws also
provide that the right of directors and officers to indemnification shall be a
contract right and shall not be exclusive of any other right now possessed or
hereafter acquired under any statute, provision of the Certificate of
Incorporation, bylaws, agreements, vote of stockholders or disinterested
directors or otherwise. The bylaws also permit the Company to secure insurance
on behalf of any officer, director, employee or other agent for any liability
arising out of his or her actions in such capacity, regardless of whether the
bylaws permit such indemnification.

         In accordance with Section 102(b)(7) of the DGCL, the Company's amended
Certificate of Incorporation provides that directors shall not be personally
liable for monetary damages for breaches of their fiduciary duty as directors
except for (i) breaches of their duty of loyalty to the company or its
stockholders, (ii) acts of omissions not in good faith or which involve
intentional misconduct or knowing violations of law, (iii) certain transactions
under Section 174 of the DGCL(unlawful payment of dividends or unlawful stock
purchases or redemptions) or (iv) transactions from which a director derives an
improper personal benefit. The effect of this provision is to eliminate the
personal liability of directors for monetary damages for actions involving a
breach of their fiduciary duty of care, including any actions involving gross
negligence.

         The Company has directors' and officers' liability insurance which
provides, subject to certain policy limits, deductible amounts and exclusions,
coverage for all persons who have been, are or may in the future be, directors
or officers of the Company, against amounts which such persons may pay resulting
from claims against them by reason of their being such directors or officers
during the policy period for certain breaches of duty, omissions or other acts
done or wrongfully attempted or alleged. Such policies provide coverage to
certain situations where the company cannot directly provide indemnification
under the DGCL.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

        Not applicable.

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:


                                       4
<PAGE>   5
             (i) To include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933, as amended (the "Securities Act");

             (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; and notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective registration statement; and

             (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 (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and 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 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities 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.

         (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.

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

         (c) Insofar as indemnification for liabilities arising under the
Securities Act 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 Commission such
indemnification is against public policy as expressed in the Securities 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


                                       5
<PAGE>   6
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
Securities Act and will be governed by the final adjudication of such issue.

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Chicago, State of Illinois, on this 9th day of
February, 2000.

ITEM 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         The following documents heretofore filed (File Number 0-27975) with the
Securities and Exchange Commission (the "Commission") by eLoyalty Corporation
(the "Company") are incorporated herein by reference:

         (a) The Information Statement/Prospectus dated February 8, 2000 and
contained in the Registration Statement on Form S-1 filed by the Company with
the Commission (Registration No. 333-94293); and

         (b) The description of the Common Stock, $.01 par value, of the Company
(the "Common Stock") and the description of the Preferred Stock Purchase Rights
of the Company (the "Rights") associated with the Common Stock, contained in the
Registration Statement on Form 8-A filed by the Company with the Commission on
January 20, 2000, including any amendments or reports filed for the purpose of
updating such descriptions.

         All documents filed by the Company pursuant to Sections 13(a), 13(c),
14 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
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, are
deemed to be incorporated by reference into this Registration Statement and to
be a part hereof from the respective dates of filing of such documents (such
documents, and the documents enumerated above, being hereinafter referred to as
"Incorporated Documents").

         Any statement contained in an Incorporated Document 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 other subsequently filed

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

         Section 145 of the Delaware General Corporation Law ("DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of such corporation), by

                                       2
3
reason of the fact that such person was an officer or director of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that such officer or
director acted in good faith and in a manner he reasonably believed to be in or
not opposed to the corporation's best interests, and, for criminal proceedings,
had no reasonable cause to believe his conduct was illegal. A Delaware
corporation may indemnify officers and directors in an action by or in the right
of the corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the corporation in the performance of his duty. Where an officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses which
such officer or director actually and reasonably incurred.

         The Company's bylaws provide that it will indemnify its directors and
officers to the fullest extent permitted by Delaware law, except that no
indemnification will be provided to a director, officer, employee or agent if
the indemnification sought is in connection with a proceeding initiated by such
person without the authorization of the board of directors. The bylaws also
provide that the right of directors and officers to indemnification shall be a
contract right and shall not be exclusive of any other right now possessed or
hereafter acquired under any statute, provision of the Certificate of
Incorporation, bylaws, agreements, vote of stockholders or disinterested
directors or otherwise. The bylaws also permit the Company to secure insurance
on behalf of any officer, director, employee or other agent for any liability
arising out of his or her actions in such capacity, regardless of whether the
bylaws permit such indemnification.

         In accordance with Section 102(b)(7) of the DGCL, the Company's amended
Certificate of Incorporation provides that directors shall not be personally
liable for monetary damages for breaches of their fiduciary duty as directors
except for (i) breaches of their duty of loyalty to the company or its
stockholders, (ii) acts of omissions not in good faith or which involve
intentional misconduct or knowing violations of law, (iii) certain transactions
under Section 174 of the DGCL(unlawful payment of dividends or unlawful stock
purchases or redemptions) or (iv) transactions from which a director derives an
improper personal benefit. The effect of this provision is to eliminate the
personal liability of directors for monetary damages for actions involving a
breach of their fiduciary duty of care, including any actions involving gross
negligence.

         The Company has directors' and officers' liability insurance which
provides, subject to certain policy limits, deductible amounts and exclusions,
coverage for all persons who have been, are or may in the future be, directors
or officers of the Company, against amounts which such persons may pay resulting
from claims against them by reason of their being such directors or officers
during the policy period for certain breaches of duty, omissions or other acts
done or wrongfully attempted or alleged. Such policies provide coverage to
certain situations where the company cannot directly provide indemnification
under the DGCL.

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:

                                       4
5
             (i) To include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933, as amended (the "Securities Act");

             (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; and notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective registration statement; and

             (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 (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and 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 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities 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.

         (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.

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

         (c) Insofar as indemnification for liabilities arising under the
Securities Act 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 Commission such
indemnification is against public policy as expressed in the Securities 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

                                       5
6
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
Securities Act and will be governed by the final adjudication of such issue.

                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Chicago, State of Illinois, on this 9th day of
February, 2000.
