statements as to the value and amount of the assets, liabilities, Profits or
Losses of the Company or any other facts pertinent to the existence and amount
of assets from which distributions to Members might properly be paid. Each
Member of the Company, in his or her individual capacity, hereby waives any and
all claims against the Managing Members for and hereby releases the Managing
Members from any and all losses, damages, liabilities, claims, causes of action,
omissions, demands, expenses or any other acts or failures to act arising from
or out of his duties as a Managing Member. Nothing contained in the last
sentence above shall constitute a waiver of any claim which the Company may have
against a Managing Member or limit any Member's authority to assert such a claim
on a derivative basis.

         5.7 REMOVAL OF MANAGING MEMBER. A Managing Member may be removed by the
affirmative vote of Members holding eighty percent (80%) of the total of all
Membership Interests. In the event of removal or resignation of a single
Managing Member, the remaining Members shall select a successor as provided in
Section 5.2, above.

         5.8 RESIGNATION. A Managing Member may resign at any time by giving
written notice to the Members. The resignation of a Managing Member shall take
effect upon receipt of such notice thereof or at such later date specified in
such notice; and,


                                     9
<PAGE>

unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective. The resignation of a
Managing Member shall not affect his rights as a Member and shall not constitute
the withdrawal of a Member.

         5.9      BANK ACCOUNTS. Each Managing Member may from time to time
open accounts in the name of the Company with such signatories as designated
by the Managing Members.

         5.10      OFFICERS. At the time of this Agreement, Clyde C. Harrison
has been elected Chief Operating Officer of the Company, Richard L. Chambers
has been elected Secretary of the Company and Robert P. Bramnik (not in his
individual capacity, but solely as a representative of Wildman) has been
elected General Counsel of the Company (collectively, the "Officers"). The
Officers shall be entitled to receive compensation for serving in such
capacity as approved by a majority of the Members. Each Officer shall hold
such office until the earlier of their respective resignations or until his
successors are elected by a majority of the Members.

         5.11     CONSULTING AND PROFESSIONAL SERVICES AGREEMENTS.

                  (a) The Members consent to the Company entering into (i) the
Amended and Restated Consulting Agreement between the Company and Cornell
Investment Advisory, LLC, dated as of April 1, 2000 and (ii) the Amended and
Restated Investment Advisory Agreement between the Company and Hart Capital
Management (a division of Arbor), dated as of April 1, 2000. Renewals of and/or
amendments to such agreements must be approved by the affirmative vote of
Members holding not less than a majority of the Percentage Interests of the
Company. Any Member who is or who has an interest in the entity with whom the
Company contracts shall abstain from voting on any such renewal or amendment.

                  (b) The Company may continue to employ Wildman, Harrold, Allen
& Dixon ("WHAD") as its counsel, provided that WHAD shall not charge the Company
fees for legal services in excess of WHAD's regular, standard hourly rates.

                                    ARTICLE 6

                          RIGHTS AND DUTIES OF MEMBERS

         6.1      RIGHTS AND DUTIES OF MEMBERS.

                  (a) Members who are not Managing Members shall not have any
         individual authority to act for or bind the Company, nor transact any
         business for the Company. However, Members who are Officers of the
         Company may act for and bind the Company if such transactions are
         within the scope of their duties as an Officer.

                  (b) Each Member agrees to indemnify, protect and hold
         harmless, on an after-tax basis, each other Member, such Member's
         permitted assigns and successors, and the Company and its agents,
         employees, officers, Managing


                                      10
<PAGE>


         Members, successors and permitted assigns, from and against all
         losses, damages, injuries, claims, demands and expenses arising out of
         such Member's acts of willful and wanton misconduct, limited to the
         extent that such losses, damages, injuries, claims, demands and
         expenses are not reimbursed under a policy of insurance carried by the
         Company.

                  (c) The Members of the Company may elect such Managing Members
         of the Company which the Members deem, in their sole discretion,
         necessary and appropriate for the Company to carry out its activities
         as contemplated in this Agreement. Each Managing Member shall be
         elected or appointed by the affirmative vote of the Members, as
         provided in subsection 5.2(b). The names of the Managing Members are
         set forth in EXHIBIT B which is attached hereto and incorporated by
         reference herein and which shall be amended when such additional or
         successor Managing Members have been duly elected or until a Managing
         Member's death, resignation or removal pursuant to Subsection 5.7 by
         the Members whenever, in their judgment, the best interests of the
         Company would be served thereby. A vacancy because of death,
         resignation, removal, disqualification or otherwise, may be filled by
         the remaining Members.

                  (d) The Members of the Company, by affirmative majority vote,
         may take any action for which a greater percentage vote is not
         required, either by virtue of Subsection 5.4 above, or otherwise.

         6.2 CONFLICTS OF INTEREST. Neither the Managing Members nor any Member
need devote full time to the Company's business, but shall devote such time as
he, in his discretion, deems necessary to make management decisions and
otherwise fulfill their responsibilities. Except as set forth below, nothing in
this Agreement shall be deemed to restrict in any way the rights of any Member,
or any affiliate of any Member, to conduct any other business or activity
whatsoever, and no such Member shall be accountable to the Company or to any
Member with respect to that business or activity even if the business or
activity competes with the Company's business. Each Member understands and
acknowledges that the conduct of the Company's business may involve business
dealings and undertakings with Members, the Managing Members, and affiliates. In
any such event, those dealings and undertakings shall be at arm's length and on
commercially reasonable terms, and neither the Managing Members nor any Officer
may use his office to obtain favorable treatment for or on behalf of himself,
his affiliates or others which would not otherwise be received in an arm's
length transaction.

                                    ARTICLE 7

                                 INDEMNIFICATION

         7.1      DEFINITIONS.
                  (a) For purposes of this Article only, a "Covered Person" is a
         person who is or was:


                                      11

<PAGE>
                           (i)     A Member;

                           (ii)    an employee, agent, director, officer,
                  member, partner, shareholder, trustee, fiduciary or
                  beneficiary of a Member;

                           (iii)   an employee, agent, director, officer,
                  partner, shareholder, trustee, fiduciary or beneficiary of
                  another person serving the Company or any entity in which the
                  Company has an interest at the request of a Managing Member
                  for the benefit of the Company.

                  (b)     For purposes of this Article, a "Designated Matter"
         with respect to a Covered Person means a matter that is claimed to be
         (in the case of an assertion by a person adverse to such Covered
         Person) a matter related to such Covered Person's status with respect
         to, duties to, or activities for the intended benefit of, the Company,
         whether such status, duties or activities are direct or are through
         Persons other than who are Covered Persons and whether such duties or
         activities occurred before or after the organization of the Company.

         7.2      EXCULPATION. No Covered Person shall be liable to the
Company or any other Member for any expenses, damages or losses with respect
to a Designated Matter other than those expenses, damages or losses directly
attributable to such Covered Person's willful misconduct or gross negligence
or failure to act in good faith or in a manner that it reasonably believed to
be in (or not opposed to) the best interests of the Company.

         7.3      INDEMNIFICATION.

                  (a)     The Company shall indemnify any Covered 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, whether
        civil, criminal, administrative or investigative (other than an action
        by or in the right of the Company or the Members generally) as a result
        of a Designated Matter against expenses (including attorneys' fees),
        judgments, fines and amounts paid in settlement actually and reasonably
        incurred by such Covered Person in connection with such action, suit
        or proceeding if (A) such Covered Person acted in good faith, was not
        grossly negligent and did not willfully engage in misconduct, and acted
        in a manner that such Covered Person reasonably believed to be in (or
        not opposed to) the best interests of the Company, and (B) with respect
        to any criminal action or proceeding, such Covered Person had no
        reasonable cause to believe his or its conduct was unlawful. The
        termination of any action, suit or proceeding by judgment, order,
        settlement, conviction, or upon a plea of NOLO CONTENDERE or its
        equivalent, shall not, of itself, create a presumption that such
        Covered Person did not act in good faith, was grossly negligent or
        committed willful misconduct or acted otherwise than in a manner which
        such Covered Person reasonably believed to be in (or not opposed to)
        the best interest of the Company, or, with respect to any criminal
        action or proceeding, had no reasonable cause to believe that his or
        its conduct was unlawful.

<PAGE>

                  (b)     The Company shall indemnify any Covered Person who
       was or is a party or is threatened to be made a party to any
       threatened,  pending or completed action or suit by or in the right of
       the Company or the Members generally to procure a judgment in its favor
       by reason of a Designated Matter against expenses (including attorneys'
       fees) actually and reasonably incurred by such Covered Person in
       connection with the defense or settlement of such action or suit if such
       Covered Person acted in good faith and in a manner such Covered Person
       reasonably believed to be in (or not opposed to) the best interests of
       the Company, except that no indemnification shall be made in respect of
       any claim, issue or matter as to which such Covered Person shall have
       been adjudged to be liable to the Company or the Members generally
       unless and only to the extent that the court in which such action or
       suit was brought shall determine upon application that, despite the
       adjudication of liability but in view of all the circumstances of the
       case, such Covered Person is fairly and reasonably entitled to indemnity
       for such expenses which such court shall deem proper.

                  (c)     To the extent that a Covered Person has been
       successful on the merits or otherwise in defense of any action, suit or
       proceeding referred to in paragraphs (a) or (b) of this subsection, or
       in defense of any claim, issue or matter therein, the Company shall
       indemnify such Covered Person against expenses (including attorneys'
       fees) actually and reasonably incurred by such Covered Person in
       connection therewith.

                  (d)     Expenses incurred by a Covered Person in defending a
       civil or criminal action, suit or proceeding with respect to a
       Designated Matter may, in the discretion of the Managing Members, be
       paid by the Company in advance of the final disposition of such
       action, suit or proceeding upon receipt of an undertaking by or on
       behalf of such Covered Person to repay such amount together with
       interest thereon if it shall ultimately be determined that such
       Covered Person is not entitled to be indemnified by the Company as
       authorized in this subsection.

                  (e)     The Company may enter into an agreement to indemnify
       any Person (whether or not a Covered Person) as to any matter (whether
       or not a Designated Matter) to the extent such agreement (i) is a
       customary practice in the industry in all material aspects, taking into
       account all facts and circumstances, or (ii) is approved by the
       Managing Members and by the holders of a majority of the Percentage
       Interests of Members.

                  (f)     The indemnification and advancement of expenses
       provided by, or granted pursuant to, the other paragraphs of this
       subsection shall not be deemed exclusive of any other rights to which
       those seeking indemnification or advancement of expenses may be
       entitled under any agreement, vote of disinterested Members or
       otherwise, both as to action in his or its official capacity and as to
       action in another capacity while holding such position, and shall
       continue as to any person or entity who has ceased to be a Member (or
       successor or assignee of a Member), director, officer, employee or
       agent of the


                                      13
<PAGE>

       Company or a Member (or successor or assignee of a Member) and shall
       inure to the benefit of the heirs, representatives, successors and
       assigns of such person or entity. The indemnification obligations
       contained in this subsection 7.3 are solely the obligations of the
       Company and no Member shall be deemed to be liable for such
       indemnification obligations by reason of its status as a Member in the
       Company.

                  (g)     The Company shall have the power to purchase and
       maintain insurance on behalf of any person or entity who is or was a
       Member (or successor or assignee of a Member), or a Covered Person,
       including a director, officer, employee or agent of the Company or of
       a Member (or successor or assignee of a Member), or is or was serving
       at the request of the Company as a director, officer, employee or
       agent of another corporation, partnership, joint venture, trust or
       other enterprise against any liability asserted against him or it and
       incurred by such person or entity in any such capacity, or arising out
       of his or its status as such, whether or not the Company would have
       the power to indemnify such person or entity against such liability
       under this subsection. However, neither (i) the availability and/or
       presence of such insurance nor (ii) any determination made by an
       insurance carrier concerning coverage issues, shall relieve or
       mitigate the Company's obligation(s) to indemnify pursuant to this
       Article 7.

         7.4      RELIANCE. The Members (and their successors and assignees),
directors, partners and officers of the Company or of a Member (or its
successors and assignees) may consult with counsel, accountants or other
independent consultants of their choosing in respect to Company affairs and
be fully protected and justified in any action or inaction which is taken in
accordance with the advice or opinion of such counsel, accountants or other
independent consultants, provided that they shall have been selected with
reasonable care.

                                    ARTICLE 8

                          ACCOUNTING; BOOKS AND RECORDS

         8.1      ACCOUNTING; BOOKS AND RECORDS. The Company shall maintain
at its principal place of business separate books of account for the Company
which shall show a true and accurate record of all costs and expenses
incurred, all charges made, all credits made and received, and all income
derived in connection with the operation of the Company business. The Company
shall keep its books and records in conformity with United States generally
accepted accounting principles applied on a consistent basis. Each Member
shall have the right, at his sole expense and with reasonable notice to every
other Member, to examine, copy, and audit the Company's books and records
during normal business hours; provided, however, that the exercise of such
right shall not disrupt the day-to-day operations of the Company.

         8.2      REPORTS. Within one hundred twenty (120) days after the end
of each Fiscal Year, the Managing Members, shall at the Company's expense,
provide each

                                      14
<PAGE>

Member with a summary report of the operations and business of the Company
during the completed fiscal year.

         8.3      TAX RETURNS. The Managing Members shall, at the Company's
expense, furnish each Member with a copy of the Schedule K-1 for the Member
as well as such other form(s) as are required to be furnished under
applicable law and regulation.

         8.4      BANKING. All available funds of the Company required for
trading activities shall be deposited in the Company's name, in such account
or accounts with domestic member banks of the Federal Reserve System as may
be approved by the Managing Members; provided, however, that the Managing
Members may elect to deposit all or a portion of the funds standing in the
Company reserves in interest-bearing accounts with, or apply such funds to
purchase short-term interest-bearing investments issued or guaranteed as to
payment by, such banks or other financial institutions that are members of
the Federal Deposit Insurance Corporation or the United States of America (or
its agencies or instrumentalities). Withdrawals of funds from Company
accounts shall be made on such signature or signatures as the Managing
Members may approve from time to time.

                                    ARTICLE 9

                  METHOD OF VOTING; MEMBER MEETINGS; AMENDMENTS

         9.1      GENERAL. Actions and decisions requiring the approval of
the Members or Managing Members pursuant to any provision of this Agreement
may be taken at a meeting of the Members or the Managing Members, as the case
may be, held either in person, by teleconference or videoconference, or by
unanimous written consent without a meeting.

         9.2      MEETINGS. Meetings of the Members, for any purpose or
purposes, may be called by any Managing Member or by any Member or Members
holding at least twenty-five percent (25%) of the Percentage Interests held
by Members.

         9.3      PLACE OF MEETINGS. The Members may designate any place, either
within or outside the State of Illinois, as the place of meeting for any meeting
of the Members. If no designation is made, or if a special meeting be otherwise
called, the place of meeting shall be the principal place of business of the
Company in the State of Illinois.

         9.4      NOTICE OF MEETINGS. Written notice stating the place, day
and hour of the meeting and the purpose or purposes for which the meeting is
called shall be delivered not less than five (5) nor more than thirty (30)
days before the date of the meeting, either personally or by mail, by or at
the direction of the Managing Members or Member or Members calling the
meeting, to each Member entitled to vote at such meeting.

         9.5      MEETING OF ALL MEMBERS. If all of the Members shall meet at
any time and place, either within or outside of the State of Illinois, and
consent to the holding of a meeting at such time and place, such meeting
shall be valid without call or notice, and at such meeting lawful action may
be taken.


                                      15
<PAGE>

         9.6      RECORD DATE. For the purpose of determining Members
entitled to notice of or to vote at any meeting of Members or any adjournment
thereof, or Members entitled to receive payment of any distribution, or in
order to make a determination of Members for any other purpose, the date on
which notice of the meeting is mailed or the date on which the resolution
declaring such distribution is adopted, as the case may be, shall be the
record date for such determination of Members.

         9.7      QUORUM. Members holding at least sixty-seven percent (67%)
of all Percentage Interests held by Members, represented in person or by
proxy, shall constitute a quorum at any meeting of Members. In the absence of
a quorum at any such meeting, a majority of the Percentage Interests so
represented may adjourn the meeting from time to time for a period not to
exceed sixty (60) days without further notice. However, if the adjournment is
for more than sixty (60) days, or if after the adjournment a new record date
is fixed for the adjourned meeting, a notice of the adjourned meeting shall
be given to each Member of record entitled to vote at the meeting. At such
adjourned meeting at which a quorum shall be present or represented, any
business may be transacted which might have been transacted at the meeting as
originally noticed. The Members present at a duly organized meeting may
continue to transact business until adjournment, notwithstanding the
withdrawal during such meeting of that number of Percentage Interests whose
absence would cause less than a quorum.

         9.8      MANNER OF ACTING. If a quorum is present, the act of the
Members holding a Majority Interest shall be the affirmative vote of Members,
unless the vote of a greater or lesser proportion or number is otherwise
required by the Act, the Articles of Organization or this Agreement. Unless
otherwise expressly provided herein or required under applicable law, only
Members who have an Interest may vote or consent upon any matter and their
vote or consent, as the case may be, shall be counted in the determination of
whether the matter was approved by the Members. In the event of an amendment
to this Agreement, the provisions of Section 6.1(d) shall govern.

         9.9      PROXIES. At all meetings of Members, a Member may vote in
person or by proxy executed in writing by the Member or by a duly authorized
attorney-in-fact. Such proxy shall be filed with the Managing Members before
or at the time of the meeting. No proxy shall be valid after eleven months
from the date of its execution, unless otherwise provided in the proxy.

         9.10     ACTION BY MEMBERS WITHOUT A MEETING. Action required or
permitted to be taken at a meeting of Members may be taken without a meeting
if the action is evidenced by one or more written consents describing the
action taken, signed by each Member entitled to vote and delivered to a
Managing Member of the Company for inclusion in the minutes or for filing
with the Company records. Action taken under this subsection 9.10 is
effective when all Members entitled to vote have signed the consent, unless
the consent specifies a different effective date.

         9.11     WAIVER OF NOTICE. When any notice is required to be given
to any Member, a waiver thereof in writing signed by the person entitled to
such notice,


                                      16
<PAGE>

whether before, at, or after the time stated therein, shall be equivalent to
the giving of such notice.

                                ASSOCIATE MEMBERS

         10.1      NEW MEMBER ADMISSION. New Members ("Associate Members")
(I.E., Members other than Founding Members and other Persons admitted
pursuant to the terms of the First Amendment) may be admitted at any time
with the affirmative vote of Members holding not less than seventy-five
percent (75%) of the Percentage Interests of Members. Such Associate Members
shall be admitted on the first day of the month specified by the Members and
shall have the same rights and duties as other Members.

         10.2      ADMISSION PROCEDURES. No Associate Member shall be
admitted unless such Associate Member executes, acknowledges and delivers to
the Company such instruments as the Managing Members may deem necessary or
advisable to effect the admission of such Associate Member, including,
without limitation, the written acceptance and adoption by such Associate
Member of the provisions of this Agreement. EXHIBIT A shall be revised from
time to time to reflect all of the Members and Associate Members of the
Company.

                                   ARTICLE 11

                                 TRANSFERABILITY

         11.1      GENERAL. No Member shall Transfer all or any portion of
his Interest without the prior written consent of either (1) all of the
Managing Members or (2) Members owning at least sixty-seven percent (67%) of
Percentage Interests held by Members, which consent may be withheld by a
Managing Member or by any Member for any reason or for no reason (it being
understood that any purported Transfer in violation of this Agreement shall
be null and void and of no force and effect).

         11.2      PERMITTED TRANSFERS. Notwithstanding anything contained in
this Agreement to the contrary (except subsection 11.3 hereof, to which this
subsection 11.2 is subject), Interests may be Transferred as follows:

                  (a)      by a Member to any member of his Family;

         deceased or adjudicated incompetent;

                  (c)      by the personal representative of a Member who is
         deceased or adjudicated incompetent to any member of such Member's
         Family;

                           DISSOLUTION AND TERMINATION

         12.1      DISSOLUTION. The Company shall be dissolved upon the
occurrence of any of the following events:

                  (a)      when the period fixed for the duration of the
         Company shall expire pursuant to subsection 1.5 hereof;

                  (b)      the vote of a Member or Members owning greater than
         sixty-seven percent (67%) of the Percentage Interests held by Members;

                  (c)      upon the death, retirement, resignation, expulsion,
         Bankruptcy or dissolution of a Member or occurrence of any other event
         which terminates the continued membership of a Member in the Company (a
         "Withdrawal Event") if such Withdrawal Event causes the Company to have
         fewer than five (5) remaining Members; or

                  (d)      as otherwise required by law.

         12.2      WINDING UP, LIQUIDATION AND DISTRIBUTION OF ASSETS. The
Company's assets on winding up shall be applied first to the expenses of the
winding up, and


                                      18
<PAGE>

thereafter all of the remaining Company assets shall be distributed in the
following order:

                  (a)      to creditors, including any Member who is also a
         creditor, in the order of priority as provided by law; and

                  (b)      to the Members in accordance with their Capital
         Account Balances.

Upon completion of the winding up, liquidation and distribution of the assets,
the Company shall be deemed terminated.

         12.3      ARTICLES OF DISSOLUTION. When all debts, liabilities and
obligations of the Company have been paid and discharged or adequate
provisions have been made therefor and all of the remaining property and
assets of the Company have been distributed, articles of dissolution, as
required by the Act, shall be executed in duplicate and filed with the
Illinois Secretary of State.

         12.4      EFFECT OF FILING OF ARTICLES OF DISSOLUTION. Upon the
filing of articles of dissolution with the Illinois Secretary of State, the
existence of the Company shall cease, except for the purpose of suits, other
proceedings and appropriate action as provided in the Act. The Managing
Members shall have authority to distribute any Company property discovered
after dissolution, convey real estate and take such other action as may be
necessary on behalf of and in the name of the Company.

         12.5      RETURN OF CONTRIBUTION; NONRECOURSE. Except as provided by
law or as expressly provided in this Agreement, upon dissolution, each Member
shall look solely to the assets of the Company for the return of its Capital
Contributions. If the Company property remaining after the payment or
discharge of the debts and liabilities of the Company is insufficient to
return the Capital Contributions of one or more Members, such Members shall
have no recourse against any Members of the Company, except as otherwise
provided by law.

         conditions set forth in this Agreement. Any such written documents to
         admit new Members need only be executed by all of the then Managing
         Members to bind the Company and by the newly admitted Member(s).

behalf of them and on behalf of the Company, the following:

                  (a) The Articles of Organization and any other certificates or
         instruments that may be required to be filed by the Company or Members
         under the laws of the State of Illinois and any other jurisdiction
         whose laws may be applicable, provided that such certificates or
         instruments have been authorized by the particular Member or Members,
         and

                  (b) Such instruments or documents as may be deemed necessary
         or desirable by the Managing Members in connection with the termination
         of the Company business, and

                  (c) Any and all amendments to the instruments described in
         clauses (a) and (b) above, provided that such amendments are either
         required by law to be filed, or are consistent with this Agreement as
         it may exist from time to time, or have been authorized by the
         particular Member or Members.

                  The foregoing grant of authority:

                           (i) Is a special power of attorney coupled with an
                  interest, is irrevocable and shall survive the death or
                  incapacity of the Member granting the power, and

                  behalf of each Member by a facsimile signature or by listing
                  all of the Members executing any instrument with a single
                  signature as attorney-in-fact for all of them, and

                  the whole or any portion of his Interest in the Company.
