                              CLICK COMMERCE, INC.

                                   ARTICLE I

                                    OFFICES

     Section 1.     Registered Office.  The registered office of Click Commerce,
Inc. (hereinafter, called the "corporation") shall be in the City of Wilmington,
County of New Castle, State of Delaware.

     Section 2.     Other Offices.  The corporation may also have offices at
such other places both within and without the State of Delaware as the Board of
Directors may from time to time determine or the business of the corporation may
require.

                                  ARTICLE II

                                 STOCKHOLDERS

     Section 1.     Place of Meetings.  Meetings of stockholders shall be held
at any place within or outside the State of Delaware designated by the board of
directors. In the absence of any such designation, stockholders' meetings shall
be held at the principal executive office of the corporation.

     Section 2.     Annual Meetings of Stockholders.  The annual meeting of
stockholders shall be held each year on a date and time designated by the board
of directors.  Any previously scheduled annual meeting of the stockholders may
be postponed by resolution of the board of directors upon public notice given
prior to the date previously scheduled for such annual meeting of the
stockholders.

     Section 3.     Special Meetings.  A special meeting of the stockholders may
be called at any time by the chairman of the board of directors, or by a
majority of the directors or by a committee of the board of directors which has
been duly designated by the board of directors and whose powers and authority,
as provided in a resolution of the board of directors, include the power to call
such meetings, but such special meetings may not be called by any other person
or persons.  Any previously scheduled special meeting of the stockholders may be
postponed by resolution of the board of directors upon public notice given prior
to the date previously scheduled for such special meeting of the stockholders.

     Section 4.     Notice of Stockholders' Meetings.  All notices of meetings
of stockholders shall be sent or otherwise given in accordance with Section 5 of
this Article II not less than ten (10) nor more than sixty (60) days before the
date of the meeting being noticed.  The notice shall

                                       1
<PAGE>

specify the place, date and hour of the meeting and in the case of a special
meeting, the general nature of the business to be transacted.

     Section 5.     Manner of Giving Notice; Affidavit of Notice.  If mailed,
notice shall be deemed to have been given when deposited in the mail, postage
prepaid, directed to the stockholder at his address appearing on the books of
the corporation or given by the stockholder to the corporation for the purpose
of notice.  An affidavit of the mailing or other means of giving any notice of
any stockholders' meeting shall be executed by the secretary, assistant
secretary or any transfer agent of the corporation giving such notice, and shall
be filed and maintained in the minute book of the corporation.

     Section 6.     Quorum.  The presence in person or by proxy of the holders
of a majority of the shares entitled to vote at any meeting of stockholders
shall constitute a quorum for the transaction of business.  The stockholders
present at a duly called or held meeting at which a quorum is present may
continue to do business until adjournment, notwithstanding the withdrawal of
enough stockholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

     Section 7.     Adjourned Meeting and Notice Thereof.  Any stockholders'
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the chairman of the meeting, but in the absence of a
quorum, no other business may be transacted at such meeting, except as provided
in Section 6 of this Article II.

          When any meeting of stockholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at a meeting at which the
adjournment is taken, unless a new record date for the adjourned meeting is
fixed, or unless the adjournment is for more than thirty (30) days from the date
set for the original meeting.  Notice of any such adjourned meeting, if
required, shall be given to each stockholder of record entitled to vote at the
adjourned meeting in accordance with the provisions of Sections 4 and 5 of this
Article II.  At any adjourned meeting the corporation may transact any business
which might have been transacted at the original meeting.

     Section 8.     Voting.  The stockholders entitled to vote at any meeting of
stockholders shall be determined in accordance with the provisions of Section 11
of this Article II.  Such vote may be by voice vote or by ballot, at the
discretion of the chairman of the meeting.  Any stockholder entitled to vote on
any matter (other than the election of directors) may vote part of the shares in
favor of the proposal and refrain from voting the remaining shares or vote them
against the proposal; but, if the stockholder fails to specify the number of
shares such stockholder is voting affirmatively, it will be conclusively
presumed that the stockholder's approving vote is with respect to all shares
such stockholder is entitled to vote.  If a quorum is present, the affirmative
vote of the majority of the shares represented at the meeting and entitled to
vote on any matter shall be the act of the stockholders, unless the vote of a
greater number or voting by classes is required by the Delaware General
Corporation Law or the certificate of incorporation or the certificate of
determination of preferences as to any preferred stock.

                                       2
<PAGE>

          At a stockholders' meeting involving the election of directors, no
stockholder shall be entitled to cumulate (i.e., cast for any one or more
candidates a number of votes greater than the number of the stockholders
shares).  The candidates receiving the highest number of votes, up to the number
of directors to be elected, shall be elected.

     Section 9.     Waiver of Notice or Consent by Absent Stockholders.  The
transactions of any meeting of stockholders, either annual or special, however
called and noticed, and wherever held, shall be as valid as though had at a
meeting duly held after regular call and notice, if a quorum be present either
in person or by proxy, and if, either before or after the meeting, each person
entitled to vote, not present in person or by proxy, signs a written waiver of
notice or a consent to the holding of the meeting, or an approval of the minutes
thereof.  The waiver of notice or consent need not specify either the business
to be transacted or the purpose of any annual or special meeting of
stockholders.  All such waivers, consents or approvals shall be filed with the
corporate records or made part of the minutes of the meeting.

          Attendance of a person at a meeting shall also constitute a waiver of
notice of such meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of matters not included in the notice
of the meeting if such objection is expressly made at the meeting.

     Section 10.    No Stockholder Action by Written Consent Without a Meeting.
Stockholders may take action only at a regular or special meeting of
stockholders.

     Section 11.    Record Date for Stockholder Notice and Voting.  For purposes
of determining the holders entitled to notice of any meeting or to vote, the
board of directors may fix, in advance, a record date, which shall not be more
than sixty (60) days nor less than ten (10) days prior to the date of any such
meeting, and in such case only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date fixed as aforesaid, except as
otherwise provided in the Delaware General Corporation Law.

          If the board of directors does not so fix a record date, the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the business day next
preceding the day on which notice is given or, if notice is waived, at the close
of business on the business day next preceding the day on which the meeting is
held.

     Section 12.    Proxies.  Every person entitled to vote for directors or on
any other matter shall have the right to do so either in person or by one or
more agents authorized by a written proxy signed by the person and filed with
the secretary of the corporation.  A validly executed proxy which does not state
that it is irrevocable shall continue in full force and effect unless (i)
revoked by the person executing it, prior to the vote pursuant thereto, by a
writing delivered to the corporation stating that the proxy is revoked or by a
subsequent proxy executed by, or attendance at the meeting and voting in person
by, the person executing the proxy, or (ii) written notice of the death or
incapacity of the maker of such proxy is received by the corporation before

                                       3
<PAGE>

the vote pursuant thereto is counted; provided, however, that no such proxy
shall be valid after the expiration of three (3) years from the date of such
proxy, unless otherwise provided in the proxy.

     Section 13.    Inspectors of Election; Opening and Closing the Polls.  The
board of directors by resolution shall appoint one or more inspectors, which
inspector or inspectors may include individuals who serve the corporation in
other capacities, including, without limitation, as officers, employees, agents
or representatives, to act at the meetings of stockholders and make a written
report thereof.  One or more persons may be designated as alternate inspectors
to replace any inspector who fails to act. If no inspector or alternate has been
appointed to act or is able to act at a meeting of stockholders, the chairman of
the meeting shall appoint one or more inspectors to act at the meeting.  Each
inspector, before discharging his or her duties, shall take and sign an oath
faithfully to execute the duties of inspector with strict impartiality and
according to the best of his or her ability.  The inspectors shall have the
duties prescribed by law.

          The chairman of the meeting shall fix and announce at the meeting the
date and time of the opening and the closing of the polls for each matter upon
which the stockholders will vote at a meeting.

     Section 14.    Nomination and Stockholder Business Bylaw.

     (A) Annual Meetings of Stockholders.

          (1) Nominations of persons for election to the board of directors of
the corporation and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (a) pursuant to
the corporation's notice of meeting, (b) by or at the direction of the board of
directors or (c) by any stockholder of the corporation who was a stockholder of
record at the time of giving of notice provided for in this bylaw, who is
entitled to vote at the meeting and who complies with the notice procedures set
forth in this bylaw.

          (2) For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (c) of paragraph (A)(1) of
this bylaw, the stockholder must have given timely notice thereof in writing to
the secretary of the corporation and such other business must otherwise be a
proper matter for stockholder action.  To be timely, a stockholder's notice
shall be delivered to the secretary at the principal executive offices of the
corporation not less than the close of business on the 120th calendar day in
advance of the first anniversary of the date the corporation's proxy statement
was released to security holders in connection with the preceding year's annual
meeting; provided, however, that if no annual meeting was held in the previous
year or the date of the annual meeting has been changed by more than thirty (30)
calendar days from the date contemplated at the time of the previous year's
proxy statement, a proposal shall be received by the corporation no later than
the close of business on the tenth day following the day on which notice of the
date of the meeting was mailed or public announcement of the date of the meeting
was made, whichever comes first.  In no event shall the public announcement of
an adjournment of an annual meeting commence a new time period for the giving of
a stockholder's notice as described above.  Such stockholder's notice shall set
forth (a) as to each person whom the stockholder proposes to nominate for

                                       4
<PAGE>

election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors in an election contest, or is otherwise required, in each case
pursuant to applicable federal securities laws, including, without limitation,
Regulation 14A under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and Rule 14a-11 thereunder (including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); (b) as to any other business that the stockholder proposes
to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the proposal is made; and (c) as to
the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (i) the name and address of such
stockholder, as they appear on the corporation's books, and of such beneficial
owner and (ii) the class and number of shares of the corporation which are owned
beneficially and of record by such stockholder and such beneficial owner.

          (3) Notwithstanding anything in the second sentence of paragraph
(A)(2) of this bylaw to the contrary, in the event that the number of directors
to be elected to the board of directors of the corporation is increased and
there is no public announcement by the corporation naming all of the nominees
for director or specifying the size of the increased board of directors at least
70 days prior to the first anniversary of the date of the preceding years annual
meeting, a stockholders notice required by this bylaw shall also be considered
timely, but only with respect to nominees for any new positions created by such
increase, if it shall be delivered to the secretary at the principal executive
offices of the corporation not later than the close of business on the 10th day
following the day on which such public announcement is first made by the
corporation.

     (B) Special Meetings of Stockholders.  Only such business shall be
conducted at a special meeting of stockholders as shall be brought before the
meeting pursuant to the corporation's notice of meeting.  A stockholder's
nomination of one or more persons for election to the board of directors shall
only be permitted to be made at a special meeting of stockholders if:  (i) the
corporation's notice of such meeting specified that directors are to be elected
at such special meeting; (ii) such stockholder was a stockholder of record
entitled to vote at the meeting at the time of giving of notice provided for in
this bylaw; and (iii) if such stockholder complies with the notice procedures
set forth in this bylaw. In the event the corporation calls a special meeting of
stockholders for the purpose of electing one or more directors to the board of
directors, any such stockholder may nominate a person or persons (as the case
may be), for election to such position(s) as specified in the corporation's
notice of meeting, if the stockholder's notice required by paragraph (A)(2) of
this bylaw shall be delivered to the secretary at the principal executive
offices of the corporation not earlier than the close of business on the 90th
day prior to such special meeting and not later than the close of business on
the later of the 60th day prior to such special meeting or the 10th day
following the day on which public announcement is first made of the date of the
special meeting and of the nominees proposed by the board of directors to be
elected at such meeting.  In no event shall the public announcement of an
adjournment of a special meeting commence a new time period for the giving of a
stockholder's notice as described above.

                                       5
<PAGE>

     (C)  General.

          (1) Only such persons who are nominated in accordance with the
procedures set forth in this bylaw shall be eligible to serve as directors.
Except as otherwise provided by law, the certificate of incorporation or these
bylaws, the chairman of the meeting shall have the power and authority to
determine the procedures of a meeting of stockholders, including, without
limitation, the authority to determine whether a nomination or any other
business proposed to be brought before the meeting was made or proposed, as the
case may be, in accordance with the procedures set forth in this bylaw and, if
any proposed nomination or business is not in compliance with this bylaw, to
declare that such defective proposal or nomination shall be disregarded.

          (2) For purposes of this bylaw, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the Exchange Act.

          (3) Notwithstanding the foregoing provisions of this bylaw, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth in this bylaw.  Nothing in this bylaw shall be deemed to affect any rights
(i) of stockholders to request inclusion of proposals in the corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act or (ii) of the holders
of any series of preferred stock, if any, to elect directors under certain
circumstances.

                                  ARTICLE III

                                   DIRECTORS

     Section 1.     Powers.  Subject to the provisions of the Delaware General
Corporation Law and any limitations in the certificate of incorporation and
these bylaws relating to action required to be approved by the stockholders or
by the outstanding shares, the business and affairs of the corporation shall be
managed and all corporate powers shall be exercised by or under the direction of
the board of directors.

     Section 2.     Number and Qualification of Directors.  The number of
directors of the corporation shall be seven (7).

     Section 3.     Election and Term of Office of Directors.  Directors shall
be elected at the annual meeting of the stockholders. Each director, including a
director elected to fill a vacancy, shall serve for a term ending on the date of
the third annual meeting following the annual meeting at which such director was
elected and until a successor has been elected and qualified or the earlier of
his resignation or removal.

     Section 4.     Vacancies.  Vacancies in the board of directors may be
filled by a majority of the remaining directors, though less than a quorum, or
by a sole remaining director.  Each

                                       6
<PAGE>

director elected to fill a vacancy shall hold office for the remainder of the
term of the person whom he succeeds, and until a successor has been elected and
qualified.

          A vacancy or vacancies in the board of directors shall be deemed to
exist in the case of the death, retirement, resignation or removal of any
director, or if the board of directors by resolution declares vacant the office
of a director who has been declared of unsound mind by an order of court or
convicted of a felony, or if the authorized number of directors be increased, or
if the stockholders fail at any meeting of stockholders at which any director or
directors are elected, to elect the full authorized number of directors to be
voted for at that meeting.

          Any director may resign or voluntarily retire upon giving written
notice to the chairman of the board, the president, the secretary or the board
of directors.  Such retirement or resignation shall be effective upon the giving
of the notice, unless the notice specifies a later time for its effectiveness.

directors as well as the committee, special meetings of committees may also be

                    INDEMNIFICATION OF DIRECTORS, OFFICERS,
                           EMPLOYEES AND OTHER AGENTS

     Section 1.     Indemnification.  The corporation shall indemnify, in the
manner and to the full extent permitted by law, any person (or the estate of any
person) who was or is a party to, or is threatened to be made a party to, any
threatened, pending or completed action, suit or proceeding, whether or not by
or in the right of the corporation, and whether civil, criminal, administrative,
investigative or otherwise, by reason of the fact that such person is a director
or officer of the corporation, and at the discretion of the board of directors
may indemnify any person (or the estate of any person) who is such a party or
threatened to be made such a party by reason of the fact that such person is or
was an employee or agent of the corporation or is or was serving at the request
of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise.  The
corporation may, to the full extent permitted by law, purchase and maintain
insurance on behalf of any such person against any liability which may be
asserted against him and may enter into contracts providing for the
indemnification of such person to the full extent permitted by law.  To the full
extent permitted by law, the indemnification provided herein shall include
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement, and, in the manner provided by law, any such expenses may be paid by
the corporation in advance of the final disposition of such action, suit or
proceeding.  The indemnification provided herein shall not be deemed to limit
the right of the corporation to indemnify any other person for any such expenses
to the full extent permitted by law, nor shall it be deemed exclusive of any
other rights to which any person seeking indemnification from the corporation
may be entitled under any agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office.

          For the purposes of this Article VI, references to "the corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors or officers so that any
person who is or was a director or officer of such constituent corporation, or
is or was serving at the request of such constituent corporation as a director
or officer of another corporation, partnership, joint venture, trust or other
enterprise, shall stand in the same position under the

                                       12
<PAGE>

provisions of this Article VI with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

          For purposes of this Article VI, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include service
as a director or officer of the corporation which imposes duties on, or involves
services by, such director or officer with respect to an employee benefit plan,
its participants or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the corporation" as referred to in
this section.

                                  ARTICLE VII

                           GENERAL CORPORATE MATTERS

     Section 1.     Record Date for Purposes Other Than Notice and Voting.  For
purposes of determining the stockholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any other lawful action, the board of
directors may fix, in advance, a record date, which date shall not precede the
date upon which the resolution fixing the record date is adopted by the board of
directors, and which shall not be more than sixty (60) nor less than ten (10)
days prior to any such action, and in such case only stockholders of record on
the date so fixed are entitled to receive the dividend, distribution or
allotment of rights or to exercise the rights, as the case may be,
notwithstanding any transfer of any shares on the books of the corporation after
the record date fixed as aforesaid, except as otherwise provided in the Delaware
General Corporation Law.

          A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the board of directors may fix a new record date for the
adjourned meeting.  In order that the corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the board
of directors may fix a record date which shall not be more than ten days after
the date upon which the resolution fixing the record date is adopted by the
board of directors.

     Section 2.     Checks, Drafts, Evidences of Indebtedness.  All checks,
drafts or other orders for payment of money, notes or other evidences of
indebtedness, issued in the name of or payable to the corporation shall be
signed or endorsed by such person or persons and in such manner as, from time to
time, shall be determined by resolution of the board of directors.

     Section 3.     Corporate Contracts and Instruments, How Executed.  The
board of directors, except as otherwise provided in these bylaws, may authorize
any officer or officers, agent or agents, to enter into any contract or execute
any instrument in the name of and on behalf of the corporation, and such
authority may be general or confined to specific instances; and,

                                       13
<PAGE>

unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or to any amount.

     Section 4.     Stock Certificates.  A certificate or certificates for
shares of the capital stock of the corporation shall be issued to each
stockholder when any such shares are fully paid.  All certificates shall be
signed in the name of the corporation by the chairman of the board or the
president or vice president and by the chief financial officer, the treasurer or
an assistant treasurer or the secretary or any assistant secretary, certifying
the number of shares and the class or series of shares owned by the stockholder.
Any or all of the signatures on the certificate may be facsimile.  In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if such person were an officer,
transfer agent or registrar at the date of issue.

     Section 5.     Lost Certificates.  Except as hereinafter in this Section 5
provided, no new stock certificate shall be issued in lieu of an old certificate
unless the latter is surrendered to the corporation and canceled at the same
time.  The board of directors may in case any stock certificate or certificate
for any other security is lost, stolen or destroyed, authorize the issuance of a
new certificate in lieu thereof, upon such terms and conditions as the board of
directors may require, including provision for indemnification of the
corporation secured by a bond or other adequate security sufficient to protect
the corporation against any claim that may be made against it, including any
expense or liability, on account of the alleged loss, theft or destruction of
such certificate or the issuance of such new certificate.

     Section 6.     Representation of Stock of Other Corporations.  The chairman
of the board, the president, or any vice president, or any other person
authorized by resolution of the board of directors by any of the foregoing
designated officers, is authorized to vote on behalf of the corporation any and
all stock of any other corporation or corporations, foreign or domestic,
standing in the name of the corporation.  The authority herein granted to said
officers to vote or represent on behalf of the corporation any and all stock by
the corporation in any other corporation or corporations may be exercised by any
such officer in person or by any person authorized to do so by proxy duly
executed by said officer.

     Section 7.     Construction and Definitions.  Unless the context requires
otherwise, the general provisions, rules of construction, and definitions in the
Delaware General Corporation Law shall govern the construction of the bylaws.
Without limiting the generality of the foregoing, the singular number includes
the plural, the plural number includes the singular, and the term "person"
includes both a corporation and a natural person.

     Section 8.     Fiscal Year.  The fiscal year of the corporation shall be
fixed by resolution of the board of directors.

                                   AMENDMENTS

     Section 1.     Amendment.  The bylaws, or any of them, may be rescinded,
altered, amended or repealed, and new bylaws may be made (i) by the board of
directors, by vote of a majority of the number of directors then in office as
directors, acting at any meeting of the board of directors, or (ii) by the
stockholders, by the vote of the holders of sixty-six and two-thirds percent
(662/3%) of the outstanding voting stock of the corporation, at any annual or
special meeting of stockholders, provided that notice of such proposed
amendment, modification, repeal or adoption is given in the notice of the annual
or special meeting; provided, however, that the bylaws can only be amended if
such amendment would not conflict with the certificate of incorporation.  Any
bylaw made or altered by the requisite number of stockholders may be altered or
repealed by the board of directors or may be altered or repealed by the
requisite number of stockholders.
