Licensee shall pay license fees in accordance with the following:

During each Year of the Renewal Term, commencing on January 1, 2003, Licensee
shall pay to Dow Jones a flat annual minimum payment of [**], payable in equal
quarterly payments of [**] (each, a "Quarterly Minimum Payment"). Each Quarterly
Minimum Payment shall be payable quarterly in advance. Prior to the commencement
of the Renewal Term, Licensee shall make a prorated payment of the Quarterly
Minimum Payment in the amount of [**] (the "Prorated Payment") for the period
commencing on the first day of the Renewal Term and ending on December 31, 2002
(the "Prorated Period").

In addition, in each Year, the Licensee will pay to Dow Jones, or the Dow Jones

Report for such quarter.

For the avoidance of doubt, Licensee will pay to Dow Jones or to the Dow Jones

     (the availability of such Loans hereunder called the "Line of Credit") in
     such amounts (the "Loans") as the Borrower may from time to time request,
     but not exceeding the amount of $20,000,000 in the aggregate at any one
     time outstanding (as reduced from time to time in accordance with Section 5
     hereof; the "Line of Credit Commitment"). The Borrower may borrow, prepay,
     repay, and reborrow from the Bank to, but not including, January 15, 2003
     (the "Termination Date"), unless sooner notified of the termination of the
     Line of Credit pursuant to Section 9.2 hereof.

          2.2 Prime Loans and LIBOR Rate Loans. Each Loan shall be either a
     Prime Loan or, if the Borrower shall so request in its notice of borrowing
     pursuant to Section 2.3, a LIBOR Rate Loan, it being understood that Prime
     Loans and LIBOR Rate Loans may both be outstanding at the same time,
     provided that no more than five (5) separate LIBOR Rate Loans shall be
     outstanding at any one time. The terms "Prime Loan" and "LIBOR Rate Loan"
     shall refer to Loans having the maturities, interest rates and other
     provisions assigned hereunder to Loans so designated. The Bank may, if it
     so elects, make any LIBOR Rate Loan by causing a foreign branch, foreign
     subsidiary, or foreign affiliate of the Bank (its "LIBOR Rate Office") to
     make such Loan; provided, that in such event, such Loan shall be deemed to
     have been made by the Bank, and the obligation of the Borrower to repay
     such Loan shall nevertheless be to the Bank and shall be deemed held by it,
     to the extent of such Loan, for the account of its LIBOR Rate Office. Each
     Prime Loan shall be in a principal amount that is an integral multiple of
     $500,000.

          2.3 Borrowing Procedures. The Borrower shall give the Bank telephonic
     notice of each requested Loan not later than 11:00 a.m., Chicago time, on
     the date on which any Prime Loan is to be made, which date shall be a
     Business Day, and no later than 11:00 a.m., Chicago time, at least three
     (3) Banking Days before the date on which any LIBOR Rate Loan is to be
     made, which date shall be a Business Day (each date of borrowing a
     "Borrowing Date"), stating the date and amount thereof, whether a LIBOR
     Rate Loan is requested, and the date when each LIBOR Rate Loan shall
     mature, as the Borrower may select pursuant to Section 2.4. Each such
     notice of a requested Loan shall be given by one of the Borrower's
     Borrowing Representatives. The Bank shall disburse the proceeds of each
     Loan in accordance with Borrower's written instructions. Notwithstanding
     any other provision of this Agreement, no Loan shall be required to be made
     hereunder if the conditions precedent to the making of such Loan specified
     in Section 8 have not been satisfied.

                                       7

          2.4 Stated Maturity of LIBOR Rate Loans. In its notice of each
     proposed LIBOR Rate Loan the Borrower shall select such date not to exceed
     one, two, three or six months after the date of such LIBOR Rate Loan, but
     no later than the Termination Date, when such LIBOR Rate Loan shall mature
     (its "Stated Maturity"); provided that in the absence of such selection the
     Borrower shall be deemed to have selected the date one (1) month after the
     date of such LIBOR Rate Loan. Such Stated Maturity shall be the day in the
     appropriate subsequent month numerically corresponding to the Borrowing
     Date of such LIBOR Rate Loan or, if there is no such day in such month or
     if the Borrowing Date is the last day of its corresponding month, the last
     day of such subsequent month; provided that if any such Stated Maturity
     would otherwise fall on a day which is not a Banking Day, said Stated
     Maturity shall be the next succeeding Banking Day (unless such succeeding
     Banking Day is the first Banking Day in a calendar month, in which case
     such Stated Maturity shall be the next preceding Banking Day).

          2.5 Illegality of Making LIBOR Rate Loans. Anything herein to the
     contrary notwithstanding, in the event that any change in (including the
     introduction of any new) applicable law, rule or regulation or in the
     interpretation or application thereof shall make it unlawful for the Bank
     to honor a request by the Borrower for a LIBOR Rate Loan, the Bank shall
     promptly notify the Borrower. If circumstances thereafter change so that it
     is no longer unlawful for the Bank to make LIBOR Rate Loans, the Bank shall
     promptly notify the Borrower.

     3. Note Evidencing Loans. The Loans shall be evidenced by a promissory note
(the "Note"), substantially in the form set forth in Exhibit A attached hereto,
with appropriate insertions, dated the Initial Borrowing Date, payable to the
order of the Bank on the Termination Date in the original Line of Credit
Commitment or in the unpaid principal amount of all of its Loans, whichever is
less. Notwithstanding the principal amount of the Note as stated on the face
thereof, the actual principal amount owing from the Borrower to the Bank or
other holder of the Note thereunder, as of any date of computation, shall be the
sum of all Loans then and theretofore made less all payments of principal
actually received by the Bank in collected funds during the same period. The
Bank shall maintain a master record of all Loans to and payments by the Borrower
hereunder and under the Note, and the aggregate unpaid principal amount shown in
such master record shall be rebuttable presumptive evidence of the principal
amount owing and unpaid on the Note. The failure to record any such amount in
such master record shall not, however, limit or otherwise affect the obligations
of the Borrower hereunder or under the Note to repay the principal amount of the
Loans, together with all interest accruing thereon. In the event of any
conflict, absent demonstrable error, the Bank's master record shall be deemed
controlling. The Note shall provide for the payment of interest and principal as
provided in Sections 4 and 5.

     4.  Interest and Other Costs of Borrowing.

          4.1 Interest. The Borrower promises to pay interest on the unpaid
     amount of each Loan for the period commencing on the date of such Loan
     until such Loan is paid in full as follows:

               (a) at all times while such Loan is a Prime Loan, at a rate per
          annum equal to the Prime Rate from time to time in effect; and

               (b) at all times while such Loan is a LIBOR Rate Loan, at a rate
          per annum equal to the LIBOR Rate from time to time in effect;

     provided, that, at the Bank's election, at any time that an Event of
     Default exists, the interest rate applicable to each Loan shall be
     increased by 2%.

          4.2 Rate Determination Conclusive. The applicable LIBOR Rate for each
     Interest Period shall be determined by the Bank, and notice thereof shall
     be given by the Bank promptly to the Borrower. Each determination of the
     LIBOR Rate by the Bank shall be conclusive and binding upon the parties
     hereto, in the absence of manifest error. The Bank shall, upon written
     request of the Borrower, deliver to the Borrower a statement showing the
     computation used by the Bank in determining the applicable LIBOR Rate
     hereunder.

          4.3  Taxes and Additional Costs.

               (a) Taxes. The Bank shall receive all payments under this
          Agreement and under the Note (including, without limitation, payments
          of interest and principal) free and clear of any and all present and
          future taxes, levies, imposts, duties, deductions, withholdings, fees,
          liabilities and similar charges imposed on or with respect to such
          payments, this Agreement or the Note ("Taxes") other than Bank Income
          Taxes. If any Taxes are required to be withheld or deducted from any
          amount payable under this Agreement or the Note (other than Bank
          Income Taxes), then the amount payable under this Agreement or the
          Note will be increased to the amount which, after deduction from such
          increased amount of all Taxes required to be withheld or deducted
          therefrom will yield to the Bank the amount stated to be payable under
          this Agreement or the Note. The Borrower will execute and deliver to
          the Bank, at its request, such further instruments as may be necessary
          or desirable to give full force and effect to any such increase,
          including, but not limited to, a new Note of the Borrower to be issued
          in exchange for the Note theretofore issued. If any Taxes other than
          those with respect to the overall net income of the Bank or its LIBOR
          Rate Office ("Bank Income Taxes") are lawfully paid by the Bank or its
          LIBOR Rate Office, the Borrower will, upon demand of the Bank,
          reimburse the Bank for such payments, together with any interest and
          penalties which may be imposed by a governmental agency, but without
          any interest imposed by the Bank or its LIBOR Rate Office, and except
          for any interest and penalties resulting from gross negligence or

                                       9
<PAGE>

          willful misconduct on the part of the Bank or its LIBOR Rate Office.
          The Bank shall subsequently return to the Borrower such additional
          amounts paid by the Borrower to the Bank on account of such Taxes
          deducted, withheld or reimbursed if and to the extent the Bank or its
          LIBOR Rate Office reasonably determines that it is able to absorb such
          additional amounts as a credit against any Taxes of any kind or nature
          due from and payable by the Bank or its LIBOR Rate Office or it is
          able to obtain a refund or reimbursement of such amounts from an
          appropriate governmental authority, provided that the Borrower shall
          deliver to the Bank the original tax receipt issued in connection with
          the payment of such withheld or deducted Taxes to an appropriate
          governmental authority and such other documents relating thereto as
          the Bank may reasonably request.

               (b) Additional Costs. If, after the date hereof, any change in
          applicable law or regulation or in the interpretation or application
          thereof by any governmental authority charged with the administration
          thereof:

                    (i) subjects the Bank or its LIBOR Rate Office to any Taxes
               of any kind whatsoever or changes the basis of taxation of
               payments to the Bank or its LIBOR Rate Office of principal or
               interest payable on its Note (except for (x) changes that affect
               Bank Income Taxes, whether in the determination of net income or
               the rate applicable thereto, and (y) Taxes for which the Bank is
               to be made whole pursuant to Section 4.3(a)); or

                    (ii) imposes, modifies or deems applicable any reserve or
               similar requirement against any Loan of the Bank or its LIBOR
               Rate Office or assets held by or deposits in or for the account
               of the Bank or its LIBOR Rate Office for the purpose of making or
               maintaining such Loan which is not otherwise taken into account
               in determining the Prime Rate or the LIBOR Rate; or

                    (iii) imposes on the Bank or its LIBOR Rate Office, directly
               or indirectly, any other material conditions, which conditions
               are outside of the Bank's control, affecting this Agreement or
               the Note held by the Bank, and the result of any of the foregoing
               is to increase the cost to the Bank or its LIBOR Rate Office of
               making or maintaining any of its Loans by an amount which the
               Bank deems to be material (any such amounts herein called
               "Additional Costs"), then the Borrower will promptly pay to the
               Bank upon its demand the additional amount or amounts necessary
               to compensate the Bank or its LIBOR Rate Office for such
               Additional Costs as and when incurred and without interest
               (except upon the Borrower's default in payment thereof).

               (c) Avoidance of Taxes or Additional Costs. If any Taxes are
          required to be deducted, withheld or reimbursed by the Borrower or any
          Additional Costs are imposed on the Borrower with respect to the Note,
          upon request of the Borrower, the Bank will use its best efforts to
          transfer the affected Loans and/or the Note to another LIBOR Rate

                                       10
<PAGE>

          Office or lending office with respect to Prime Loans ("Domestic
          Lending Office"), which Domestic Lending Office shall be an office,
          branch or subsidiary of the Bank, in a jurisdiction where all such
          Taxes and Additional Costs may be avoided altogether or, if avoidance
          is not feasible, reduced to the extent reasonably possible, provided
          that such transfer will not result in any increased Taxes payable by
          the Bank or its LIBOR Rate Office (including, without limitation, Bank
          Income Taxes) and not reimbursed by the Borrower. The Borrower will
          use its best efforts fully to cooperate with such transfer by the Bank
          to the extent permissible under applicable law. The Bank shall not be
          liable for its failure for any reason whatsoever to transfer the
          affected Loans or its Note or to take other appropriate action to
          avoid such Taxes and Additional Costs other than with respect to the
          Bank's gross negligence or willful misconduct.

          4.4 Compensation for Prepayment of or Failure to Borrow LIBOR Rate
     Loan. If the Borrower (a) makes a prepayment of any LIBOR Rate Loan under
     Section 5 on a day other than the Stated Maturity thereof or (b) fails to
     borrow any LIBOR Rate Loan on the Borrowing Date requested therefor
     pursuant to Section 2.3 prior to the last Business Day of any Interest
     Period, the Borrower agrees to indemnify the Bank against any loss
     (including any loss on redeployment of the funds repaid), cost or expense
     incurred by the Bank as a result of such prepayment. A certificate from the
     Bank of such loss or expense (including calculations in reasonable detail)
     shall, in absence of manifest error, be conclusive and binding on the
     Borrower.

          4.5 Computation of Interest. Interest on Prime Loans shall be computed
     for the actual number of days elapsed on the basis of a year consisting of
     360 days. Interest on LIBOR Rate Loans shall be computed on the basis of a
     360-day year and for actual days elapsed. Whenever any payment to be made
     hereunder shall fall due on a day which is not a Business Day, such payment
     may be made on the next succeeding Business Day and such extension of time
     shall be included when computing interest in connection with such payment.

     5.  Making and Proration of Payments; Prepayments; Offset.

          5.1 Making of Payments to the Bank. The Borrower shall make all
     payments on the Note and otherwise under this Agreement in Dollars in
     immediately available funds to the Bank at its office in Chicago, Illinois,
     not later than 2:00 p.m., Chicago time, on the date due; and funds received
     after that hour shall be deemed to have been received by the Bank on its
     next following Business Day.

          5.2  Mandatory Prepayments.

               (a) Illegality. If any change in applicable law or regulation or
          in the interpretation thereof by any governmental authority charged
          with the administration thereof shall make it unlawful for the Bank to
          continue to maintain any of its Loans, and the Bank is unable to

                                       11
<PAGE>

          remedy such circumstance by transferring such Loan or Loans to another
          LIBOR Rate Office pursuant to Section 4.3(c), then the Borrower will,
          upon ten (10) Business Days' (where practicable) notice from the Bank,
          prepay such Loan or Loans in full, together with accrued interest
          thereon to the date of prepayment. If possible, the Bank shall not
          require such prepayment of any LIBOR Rate Loan before its Stated
          Maturity.

               (b) Termination of Credit. If the Bank shall, in its sole
          discretion at any time that an Event of Default shall have occurred
          and remain continuing, elect to terminate the Line of Credit before
          the Termination Date, then the Borrower shall repay the aggregate
          principal amount of (i) all Prime Loans then outstanding (together
          with accrued but unpaid interest thereon), not later than ten (10)
          Business Day after the effectiveness of such termination and (ii) each
          LIBOR Rate Loan then outstanding (together with accrued but unpaid
          interest thereon) at its Stated Maturity (without acceleration).

          5.3 Reduction or Termination of Line of Credit; Optional Prepayments
     and Maturity of Principal.

               (a) Voluntary Reduction or Termination of the Line of Credit. The
          Borrower may from time to time on at least five (5) Business Days'
          prior written notice received by the Bank permanently reduce the Line
          of Credit Commitment to an amount not less than the aggregate amount
          of all Loans then outstanding. Any such reduction shall be in an
          amount not less than $500,000 or an integral multiple thereof.
          Concurrently with any reduction to the Line of Credit Commitment to
          zero, the Borrower shall pay all interest on the Loans and all Non-Use
          Fees (as hereinafter defined) owing hereunder.

               (b) Prime Loans. The Borrower shall pay on the Termination Date
          or at earlier maturity by acceleration (or otherwise), the aggregate
          unpaid principal amount of all Prime Loans then outstanding. The
          Borrower shall have the right at any time and from time to time before
          the Termination Date, upon written notice from a Borrowing
          Representative to the Bank not later than noon, Chicago time, of the
          day that payment is made, to prepay in whole or in part and without
          premium or penalty the aggregate principal amount of all Prime Loans
          then outstanding; provided that any such partial prepayment shall be
          in an aggregate principal amount that is an integral multiple of
          $500,000. Any prepayment of principal of the Prime Loans shall include
          accrued interest to the date of prepayment on the principal amount
          being prepaid.

               (c) LIBOR Rate Loans. The Borrower shall pay the entire principal
          amount of any LIBOR Rate Loan at its maturity (whether at Stated
          Maturity, by acceleration or otherwise). The Borrower shall have the
          right at any time to prepay in whole, but not in part, the aggregate

                                       12
<PAGE>

          principal amount of any LIBOR Rate Loan, before the Stated Maturity of
          such Loan, subject to payment of any amount owing pursuant to
          Section 4.4.

          5.4 Conversion between Types of Loans. The Borrower may effect payment
     or prepayment of any LIBOR Rate Loan or Prime Loan by requesting a Loan of
     the other type to be made on the date of such payment or prepayment in an
     amount equal to the principal amount of the Loan being paid or prepaid,
     upon proper notice pursuant to Section 2.3, and in such request directing
     the Bank to apply the proceeds of the requested Loan to payment on the
     applicable Borrowing Date of the principal of such Loan being paid or
     prepaid. If the Borrower shall fail to pay any LIBOR Rate Loan at its
     Stated Maturity, the Bank shall automatically effect payment of the
     principal thereof by making a Prime Loan in the principal amount of such
     LIBOR Rate Loan.

          5.5 Interest. The Borrower shall pay accrued interest on Prime Loans
     monthly in arrears on the last day of each month, beginning with the first
     of such dates to occur after the Initial Borrowing Date and at maturity
     (whether by acceleration or otherwise), and on each LIBOR Rate Loan at its
     maturity (whether at Stated Maturity, by acceleration or otherwise).
     Notwithstanding anything to the contrary contained herein, accrued interest
     on each LIBOR Rate Loan with a six-month Interest Period shall be payable
     on the three-month anniversary of the first day of such Interest Period and
     at maturity. After the maturity (whether by acceleration or otherwise) of
     any Loan hereunder, the Borrower shall pay accrued interest on such Loan on
     demand.

          5.6 Offset. In addition to and not in limitation of all rights of
     offset that the Bank or any other holder of the Note may have under
     applicable law, the Bank or such other holder shall, upon the occurrence
     and during the continuance of any Event of Default described in Section
     9.1(a) or (c) or any other Potential Default described in the remaining
     subsections of Section 9.1 after the expiration of any applicable grace or
     cure periods, have the right to appropriate and apply to the payment of the
     Note any and all balances, credits, deposits, accounts or moneys of the
     Borrower then or thereafter with the Bank or such other holder.

          5.7 Arrangement Fee. The Borrower agrees to pay to the Bank an
     arrangement fee as set forth in a separate letter agreement between the
     Borrower and the Bank (the "Fee Letter").

          5.8 Non-Use Fee. The Borrower agrees to pay to the Bank a non-
     utilization fee ("Non-Use Fee") equal to 0.25% per annum of the total of
     (a) the Line of Credit Commitment, less (b) the sum of (i) the daily
     average of the aggregate principal amount of all Loans outstanding, which
     Non-Use Fee shall be (A) calculated on the basis of a year consisting of
     360 days, (B) paid for the actual number of days elapsed, and (C) payable
     in arrears on the first day of each quarter commencing on January 2, 2002,
     and on the Termination Date.

                                       13

     6. Representations and Warranties. To induce the Bank to make the Loans
hereunder, the Borrower represents and warrants to the Bank that, as of the date
hereof,:

          6.1 Organization, Good Standing and Power. Borrower is a Delaware not-
     for-profit corporation validly organized, existing and in good standing,
     under the laws of the State of Delaware; is duly qualified to do business
     as a foreign corporation in each jurisdiction where the nature of the
     Borrower's business requires such qualification, except where failure so to
     qualify would not have a material adverse effect on the Borrower's
     financial condition or ability to enter into and perform its obligations
     under this Agreement, the Note and each other document executed in
     connection therewith, and has full power and authority and holds all
     requisite governmental licenses, permits and other approvals necessary to
     permit the Borrower to enter into and perform its obligations under this
     Agreement, the Note and each other document executed in connection
     therewith and to conduct the Borrower's business substantially as currently
     conducted by it, except for such licenses, permits or approvals where such
     failure to hold would not have a material adverse effect on the Borrower's
     financial condition or ability to enter into and perform its obligations
     under this Agreement, the Note and each other document executed in
     connection herewith.

          6.2 Corporate Authority. Borrower has the power and authority to enter
     into and deliver this Agreement, to make borrowings hereunder, to execute
     and deliver the Note and to incur the obligations provided for herein and
     therein, all of which have been duly authorized by all requisite corporate
     action.

          6.3 Authorizations. No approval, authorization or other action by, or
     filing with, any governmental authority is required in connection with the
     borrowings hereunder, the execution and delivery of this Agreement and the
     Note, and the performance by the Borrower of its obligations hereunder and
     thereunder.

          6.4 No Conflicts. The execution and delivery of this Agreement and the
     Note by the Borrower and the performance by the Borrower of its obligations
     hereunder and thereunder do not conflict with or result in a violation of
     any statute, regulation or rule or the certificate of incorporation or by-
     laws of the Borrower or of any material agreement, instrument, order, writ,
     judgment or decree to which it is a party or is subject, or result in or
     require the creation or imposition of any lien on any of the properties of
     the Borrower.

          6.5 Binding Agreement. This Agreement constitutes, and the Note, when
     issued and delivered pursuant hereto for value received, will constitute,
     valid and binding obligations of the Borrower enforceable in accordance
     with their respective terms, subject, as to the enforcement of remedies,
     (i) to applicable bankruptcy, reorganization, insolvency, moratorium or
     other similar laws of general application affecting creditors' rights from
     time to time in effect and (ii) to general principles of equity (regardless
     of whether such enforceability is considered in a proceeding in equity or
     at law).

                                       14
<PAGE>

          6.6 Financial Statements. The Borrower's annual audited financial
     statements as at December 31, 2000 and its unaudited quarterly financial
     statement as at September 30, 2001, copies of which have been furnished to
     the Bank, have been prepared, in the case of the annual financial
     statements, in conformity with generally accepted accounting principles
     ("GAAP") consistently applied and all of such financial statements
     accurately present the financial condition of the Borrower as at such dates
     and the results of its operations for the periods then ended, and since
     such dates there has been no material adverse change in the Borrower's
     financial condition, operations, assets or business except as set forth in
     the Borrower's Financials. The Borrower has not incurred, or entered into
     any agreement or instrument whereby it may incur, any Indebtedness for
     borrowed money that is superior to or ranks pari passu in right of payment
     with the Loans or guaranteed the Indebtedness of any other person except as
     permitted under Section 7.9.

          6.7 Litigation. Except as disclosed in Exhibit C attached hereto,
     there are no pending or, to the knowledge of the Borrower, threatened
     actions, suits, proceedings or investigations affecting the assets or
     revenues of the Borrower before any court or arbitrator or before or by any
     governmental authority that, in any one case or in the aggregate, if
     determined adversely to the interests of the Borrower, would reasonably be
     expected to have a material adverse effect on its financial condition,
     operations, assets, business or properties or that purports to affect the
     legality, validity or enforceability of this Agreement, the Note or any
     other document executed in connection therewith. Other than any liability
     incident to such litigation or other proceedings or investigations, the
     Borrower does not have any material Contingent Liabilities not provided for
     or disclosed in the Financials referred to in Section 6.6.

          6.8 Taxes. The Borrower has filed all Federal and material tax returns
     and reports required by law to have been filed by it and has paid all taxes
     and governmental charges thereby shown to be owing, except any such taxes
     or charges which the Borrower is diligently contesting in good faith by
     appropriate proceedings and for which adequate reserves in accordance with
     GAAP have been set aside on the Borrower's books.

          $1,000,000 in the aggregate, or default in the performance or
          observance of any obligation or condition with respect to any such
          Indebtedness if the effect of such default is to accelerate the
          maturity of any such Indebtedness or to permit the holder or holders
          thereof, or any trustee or agent for such holders, to cause such
          Indebtedness to become due and payable prior to its expressed
          maturity;

               (c) Bankruptcy, Insolvency, etc. The Borrower becomes insolvent
          or generally fails to pay, or admits in writing its inability to pay,
          debts as they become due; or the Borrower applies for, consents to, or

          application, consent or acquiescence, a trustee, receiver or other
          custodian is appointed for the Borrower or for a substantial part of
          its property and is not discharged within forty-five (45) days; or any
          bankruptcy reorganization' debt arrangement, or other case or
          proceeding under any bankruptcy or insolvency law, or any dissolution
          or liquidation proceeding, is commenced in respect of the Borrower,
          and, if such case or proceeding is not commenced by the Borrower, it
          is consented to or acquiesced in by the Borrower or remains for forty-
          five (45) days undismissed; or the Borrower takes any corporate action
          to authorize, or in furtherance of, any of the foregoing;

               (d) Non-Compliance with this Agreement. Failure by the Borrower
          to comply with or to perform any provision of this Agreement (and not
          constituting an Event of Default under any of the preceding provisions
          of this Section 9) and continuance of such failure for fifteen (15)
          days after the earlier of (i) the date on which Borrower had, or
          should have had knowledge of such failure, or (ii) notice thereof to
          the Borrower from the Bank; or

               (e) Warranties. Any representation or warranty made by or on

          as of which the facts therein set forth are stated or certified.

               (f) Trading Suspension. There shall have occurred a suspension or
          material limitation in trading generally at the Borrower.

          9.2 Effect of Event of Default. If any Event of Default described in
     Section 9.1(c) shall occur, the Line of Credit (if it has not theretofore
     terminated) shall immediately terminate and the Note shall become
     immediately due and payable, all without notice of any kind; and, in the
     case of any other Event of Default, the Bank may declare the Line of Credit
     (if it has not theretofore terminated) to be terminated and the Note to be
     due and payable, whereupon the Line of Credit (if it has not theretofore
     terminated) shall immediately terminate and the Note shall become
     immediately due and payable, all without notice of any kind. The Bank shall
     promptly advise the Borrower of any such declaration, but failure to do so
     shall not impair the effect of such declaration. Notwithstanding the
     foregoing, the effect as an Event of Default of any event described in this
     Section 9 may be waived by the written consent of the Bank.

     10. Miscellaneous.

          10.1 Waiver; Amendments. No delay on the part of the Bank in the
     exercise of any right, power or remedy shall operate as a waiver thereof,
     nor shall any single or partial exercise by it of any right, power or
     remedy preclude other or further exercise thereof, or the exercise of any
     other right, power or remedy. No amendment, modification or waiver of, or
     consent with respect to, any provision of this Agreement or the Note shall
     in any event be effective unless the same shall be in writing and signed
     and delivered by the Bank and the Borrower, and any such amendment,
     modification, waiver or consent shall be effective only in the specific
     instance and for the specific purpose for which given.

     hereunder or with respect to the Note will be duly given when delivered in

     Section, or if sent by certified or registered mail shall be deemed
     delivered on the third Business Day following its deposit in the United
     States mails, if not actually received before such date. A communication,
     demand or notice given pursuant to this Section shall be addressed to each
     party at its address shown below its signature hereto, or at such other
     address as it may, by written notice received by the other parties to this
     Agreement, have designated as its address for such purpose.

          10.3 Computations. Where the character or amount of any asset or
     liability or item of income or expense is required to be or has been
     determined, or any consolidation or other accounting computation is

<PAGE>

     required to be or has been made, for the purpose of this Agreement, such
     determination or calculation shall be or has been, to the extent applicable
     and except as otherwise specified in this Agreement, made in accordance
     with GAAP in the United States applied on a basis consistent with those at
     the time in effect.

     shall immediately advise the Borrower of such transfer and use its
     reasonable efforts to obtain the Borrower's consent to such transfer;
     provided, however, that failure on the part of the Bank to obtain such
     consent shall in no way prevent the Bank from making such transfer; and the
     Borrower shall be entitled conclusively to assume that no transfer of the
     Note has been made unless and until the Borrower shall have received
     written notice to the contrary. Each transferee of the Note shall take such
     Note subject to the provisions of this Agreement and to any waiver or
     consent given or other action taken hereunder, before the receipt by the
     Borrower of written notice of such transfer, by each previous holder of the
     Note; and, except as expressly otherwise provided in such notice, the Bank
     and the Borrower shall be entitled conclusively to assume that the
     transferee named in such notice shall thereafter be vested with all rights
     and powers under this Agreement of the Bank under the Note.

          10.5 Regulation U. The Bank represents that it in good faith is not
     relying, either directly or indirectly, upon any stock (as such term is
     defined in Regulation U promulgated by the Board of Governors of the
     Federal Reserve System) as collateral security for the extension or
     maintenance by it of any credit provided for in this Agreement.

          10.6 Costs, Expenses and Taxes. The Borrower agrees to pay on demand
     all reasonable out-of-pocket costs and expenses of the Bank (including the
     reasonable fees and out-of-pocket expenses of counsel for the Bank) in

     this Agreement, the Note, and all other instruments or documents provided

     herewith, and all reasonable out-of-pocket costs and expenses (including
     reasonable attorneys' fees and legal expenses) incurred by the Bank in
     connection with the enforcement of this Agreement, the Note, any such other
     instruments or documents or any collateral security. The obligations

     efforts to afford the Borrower the opportunity to object to such
     disclosure.

     Re:  Line of Credit Agreement dated January 15, 2002 (the "Agreement")
          between Board of Trade of the City of Chicago

Ladies and Gentlemen:

     We are counsel for the Board of Trade of the City of Chicago, Inc. (the
"Company") and have represented the Company in connection with its execution and
delivery of a Line of Credit Agreement among the Company and LaSalle Bank
National Association of even date herewith (the "Line of Credit Agreement"),
providing for Loans in an aggregate principal amount not to exceed $20,000,000.
All capitalized terms used in this opinion shall have the meanings attributed to
them in the Line of Credit Agreement.

     We have examined the Company's articles of incorporation, by-laws,
resolutions, the Line of Credit Agreement, the Note and such other matters of
fact and law which we deem necessary in order to render this opinion.  Based
upon the foregoing, it is our opinion that:

     1.   The Company is a not-for-profit corporation duly incorporated, validly
existing and in good standing under the laws of the State of Delaware and has
all requisite authority to conduct its business in Illinois and each other
jurisdiction in which its business is conducted.

     2.   The execution and delivery of the Line of Credit Agreement and the
Note by the Company and the performance by the Company of the obligations
thereunder have been duly authorized by all necessary corporate action and
proceedings on the part of the Company and will not (a) require any consent of
the Company's members; (b) violate any law, rule, regulation, order, writ,
judgment, injunction, decree or award binding on the Company or the Company's
articles of incorporation or by-laws or any indenture, instrument or agreement
binding upon the Company; or (c) result in, or require, the creation or
imposition of any Lien pursuant to the provisions of any indenture, instrument
or agreement binding on the Company.

     3.   The Line of Credit Agreement and the Note have been duly executed and
delivered by the Company and constitute legal, valid and binding obligations of
the Company enforceable in accordance with their terms except to the extent the
enforcement thereof may be limited by bankruptcy, insolvency or similar laws

                                     F-32

<PAGE>

affecting the enforcement of creditors' rights generally and subject also to the
availability of equitable remedies if equitable remedies are sought.

     4.   Exhibit C to the Line of Credit Agreement describes all pending and
threatened material litigation and proceedings against the Company of which we
have knowledge.

     5.   No approval, authorization, consent, adjudication or order of any
governmental authority, which has not been obtained by the Company, is required
to be obtained by the Company (or any subsidiary) in connection with the
execution and delivery of the Line of Credit Agreement or the Note, the
borrowings under the Line of Credit Agreement or the Note or in connection with
the payment by the Company of the obligations thereunder.

                                              Very truly yours,

                                              ------------------------------
