                               SECURITY AGREEMENT

     This Security Agreement (hereinafter called "Agreement") is between Board
of Trade of the City of Chicago, a Delaware corporation (hereinafter called
"Debtor"), and Hitachi Credit America Corp., a Delaware corporation (hereinafter
called "Secured Party").

     1.  Grant of Security Interest.  Subject to the terms and conditions of
this Agreement, Debtor, for consideration, and to secure the full and prompt
payment, observance and performance when due of all present and future
obligations and indebtedness of Debtor to Secured Party pursuant to the Note (as
defined below), whether at the stated time, by acceleration or otherwise,
howsoever created, arising or evidenced, whether direct or indirect, absolute or
contingent, and whether now or hereafter existing, or due or to become due, and
whether such indebtedness from time to time is reduced and thereafter increased,
including without limitation, the following:

     (a) Any and all amounts owed by Debtor under, in connection with, and/or
pursuant to the indebtedness evidenced by that certain Promissory Note of even
date herewith, in the original principal sum of Ten Million Dollars and No Cents
($10,000,000.00) (the "Note"), with interest thereon according to the provisions
thereof, and all obligations thereunder, in connection therewith and/or pursuant
to any and all agreements and other documents in connection therewith; and

     (b) All sums advanced or expenses or costs paid or incurred (including
without limitation reasonable attorneys' fees and other legal expenses) by
Secured Party pursuant to or in connection with the Note or any other agreements
and documents in connection therewith plus applicable interest on such sums,
expenses or costs; and

     (c) Any extensions, modifications, changes, substitutions, restatements,
renewals or increases or decreases of any or all of the indebtedness referenced
above;

hereby grants to Secured Party a security interest in the collateral described
in Schedule 1 to this Agreement and made a part hereof (hereinafter collectively
called the "Collateral").

     2.  Representations, Warranties and Covenants of Debtor.  Debtor expressly
represents, warrants and covenants as follows:

     (a) The address appearing with Debtor's signature below is the address of
Debtor's chief executive office or, if Debtor has no place of business, Debtor's
residence.  If the Collateral is not located at Debtor's address appearing
below, it will be located at:  [Not Applicable].

     (b) If Debtor does not keep the records concerning the Collateral and
concerning accounts, general intangibles, mobile goods and contract rights at
the address appearing below, these records will be located at: [Not Applicable].

     (c) Debtor will give Secured Party (1) thirty (30) days prior written
notice of any change in (i) Debtor's chief executive office (or, if Debtor has
no place of business, Debtor's residence), the location of the Collateral or the
location of the records described above, (ii) the principals responsible for the
management of Debtor's business, (iii) Debtor's corporate structure or identity
(other than the contemplated conversion to a for-profit corporation; provided,
however, Debtor shall provide written notice to Secured Party of any such
conversion within thirty (30) days after it is completed), and (iv) Debtor's
name or trade name, or prior to commencing to use an assumed name not set forth
in this Agreement and (2), if Debtor is a for-profit corporation, prompt written
notice of the sale by any

<PAGE>

shareholder of Debtor of any shares of the stock representing five percent (5%)
or more of the outstanding stock of Debtor (other than shares transferred or
issued in conjunction with a contemplated conversion as provided in (c)(1)(iii)
above).

     (d) If any of the Collateral is to be or has been attached to real estate,
the legal description of the real estate is attached to this Agreement as
Schedule 2 and made a part hereof.

     (e) If Debtor does not have a record interest in the real estate described
above, the record owner is indicated on the attached Schedule 2.

     (f) Without the prior written consent of Secured Party, Debtor will not
move, sell, lease, permit any encumbrance (other than inchoate tax liens with
respect to taxes not yet due and payable) on or otherwise dispose of the
Collateral, other than its (i) inventory in the ordinary course of its business
and (ii) equipment no longer used or useful in Debtor's business; provided,
however, Debtor shall not dispose of any such equipment with an aggregate value
in excess of $500,000 in any one calendar year.  Debtor represents and warrants
that Debtor is the sole owner of the Collateral, free and clear of all liens,
charges, interests, and encumbrances (other than inchoate tax liens with respect
to taxes not yet due and payable), other than in favor of Secured Party, that no
other person or other entity has any interest in the Collateral whatsoever, and
that Debtor will defend same against all adverse claims and demands.

     (g) Debtor will keep the Collateral insured by such companies, in such
amounts and against such risks as shall be reasonably acceptable to Secured
Party, with loss payable and additional insured clauses with respect to the
Collateral in favor of Secured Party as are reasonably satisfactory to Secured
Party.  Debtor will deposit such insurance policies (or certified copies of such
insurance policies) with Secured Party which policies shall contain the
insurer's agreement to give Secured Party thirty (30) days' prior written notice
before cancellation or material change thereof.  All amounts received by Secured
Party in payment of insurance losses or return of unearned premium may (1) at
Secured Party's option, be applied to the indebtedness by Secured Party, or all
or any part thereof may be used for the purpose of repairing, replacing or
restoring the Collateral or (2) at Debtor's option, be used for the purpose of
repairing, replacing or restoring the Collateral with similar equipment that is
of equal or greater value and utility at a cost not to exceed $500,000 or if the
cost is equal to or greater than $500,000, at Debtor's request with the consent
of Secured Party, which consent shall not be unreasonably withheld; any
replacements hereunder will be deemed to become part of the Collateral and
Debtor agrees to execute and timely deliver to Secured Party financing
statements or any other documents Secured Party deems necessary to perfect or
protect Secured Party's security interest in the Collateral.  If Debtor fails to
maintain satisfactory insurance, Secured Party shall have the option, but not
the obligation, upon ten (10) days' prior written notice to Debtor, to obtain
such insurance in such amounts as Secured Party deems necessary, and Debtor
agrees to repay, with interest at the highest rate applicable to any
indebtedness which this Agreement secures, all amounts so expended by Secured
Party.

     (h) Debtor represents and warrants to Secured Party that all financial
statements and credit applications delivered by Debtor to Secured Party
accurately reflect in all material respects the financial condition and
operations of Debtor at the times and for the periods therein stated.  So long
as this Agreement is in force and effect, Debtor agrees to deliver to Secured
Party (1) within ninety (90) days after the end of each of Debtor's fiscal
quarters, a complete and accurate copy of Debtor's financial statements,
including consolidated statements of cash flow, and a consolidated balance sheet
and statement of income, together with all schedules, and (2) within one hundred
and twenty (120) days after the end of each of Debtor's fiscal years, a complete
and accurate copy of Debtor's audited financial statements, including
consolidated statements of cash flow, and a consolidated balance sheet and
statement of income, together with all schedules, all prepared in accordance
with generally accepted accounting principles by independent certified public
accountants reasonably acceptable to Secured Party, showing the consolidated
financial position of Debtor at the close of such fiscal quarter, and
concurrently therewith a certificate of its president or chief financial officer
to the effect that such officer is not aware

of any condition or event which constitutes a default under this Agreement or
which, with the mere passage of time or notice, or both, would constitute a
default under this Agreement.

     (i) Secured Party shall not be deemed to have waived any of its rights in
any Collateral unless such waiver is in writing and signed by an authorized
representative of Secured Party.  No delay or omission by Secured Party in
exercising any of Secured Party's rights shall operate as a waiver thereof or of
any other rights.  Secured Party shall have, in addition to all other rights and
remedies provided by this Agreement or applicable law, the rights and remedies
of a secured party under the Uniform Commercial Code.

     (j) Debtor will maintain the Collateral in good condition and repair,
ordinary wear and tear excepted, and will pay promptly all taxes, levies, and
encumbrances and all repair, maintenance and preservation costs pertaining to
the Collateral.  If Debtor fails to make such payments, Secured Party shall have
the option, but not the obligation, upon ten (10) days' prior written notice, to
pay the same and Debtor agrees to repay, with interest at the highest rate
applicable to any indebtedness which this Agreement secures, all amounts so
expended by Secured Party.  Debtor will at any time and from time to time but no
more than once per quarter, upon the reasonable request of Secured Party and
upon reasonable prior notice, give any representative of Secured Party access
during normal business hours to inspect the Collateral or the books and records
thereof.

     (k) Debtor agrees to pay to Secured Party on demand all reasonable
expenses, including reasonable attorney fees and expenses, incurred by Secured
Party in protecting or enforcing its rights in the Collateral or otherwise under
this Agreement.  After deducting all said expenses, the remainder of any
proceeds of sale or other disposition of the Collateral shall be applied to the
indebtedness due Secured Party in such order of preference as Secured Party
shall reasonably determine.

     (l) Debtor hereby agrees to faithfully preserve and protect Secured Party's
first priority security interest in the Collateral at all times, and further
agrees to execute and deliver, from time to time, any and all further, or other,
documents, instruments, continuation statements and perform or refrain from
performing such acts, as Secured Party may reasonably request to effect the
purposes of this Agreement and to secure to Secured Party the benefits of all
the rights, authorities and remedies conferred upon Secured Party by the terms
of this Agreement.

     3.  Defaults.  The occurrence of any of the following events shall
constitute a default hereunder:

     (a) The failure of Debtor to make any payment when due on any indebtedness
to Secured Party pursuant to the Note, or a default in any provision of the Note
secured hereby or any other encumbrance or agreement securing the Note;

     (b) The breach of or failure to perform promptly any obligation or covenant
set forth in this Agreement, the Note or any other agreement secured hereby or
securing the Note within ten (10) days after notice thereof or if the nature of
the breach is such that it cannot reasonably be cured within such ten (10) day
period, for a period (which period shall not exceed thirty (30) days) which is
reasonably required to effect a cure, so long as Debtor commences the cure
within such ten (10) day period and Debtor diligently pursues such cure;

     (c) The suspension of business, insolvency, failure generally to pay debts
as they became due, in each case on the part of Debtor's business; the
concealment or removal of any substantial portion of Debtor's property with the
intent to hinder, delay or defraud any one or more creditors; the existence or
creation of any material lien, including without limitation any tax or judgment
lien, upon the Collateral; an assignment for the benefit of creditors; the
commencement of any proceedings against Debtor (under the Bankruptcy Code or
otherwise) seeking to adjudicate it bankrupt or insolvent, or seeking
reorganization, arrangement, adjustment or composition of it or its debts under
any law relating to

Initial DV MF

                                       3
<PAGE>

bankruptcy, insolvency or reorganization or relief of debtors or seeking the
appointment of a receiver, trustee or custodian for Debtor or for the Collateral
and it is not dismissed within sixty (60) days after its filing, or is filed by
Debtor, or Debtor takes any action to authorize any of the foregoing matters; or
the institution by Debtor of any liquidation, dissolution or reorganization
proceedings with respect to Debtor;

     (d) The failure to effectively and promptly discharge, stay or indemnify
against, to Secured Party's reasonable satisfaction, any material lien or
attachment against any of the Collateral;

     (e) Any representation or warranty made by Debtor contained herein or in
any other document delivered by or on behalf of Debtor to Secured Party in
connection herewith shall be false or misleading when made;

     (f) Any guaranty of the obligations described herein ceases to be
effective, except pursuant to a written release from Secured Party, or any
guarantor denies liability thereunder, or one of the events described in
Paragraph 3(c) hereof occurs with respect to any guarantor, or any default
occurs under any such guaranty;

     (g) If Debtor is a corporation, the occurrence of any of the following
without the Secured Party's written consent: the sale, pledge or assignment by
the shareholders of Debtor of any shares of the stock representing thirty
percent (30%) or more of the outstanding stock of Debtor; the transfer not in
the ordinary course of Debtor's business of more than thirty percent (30%) of
the value of Debtor's assets; the merger or consolidation of Debtor with another
company or entity; the change of the Debtor's name; the conversion of Debtor's
legal structure to an entity form other than a corporation or the liquidation of
Debtor;

     (h) The occurrence of any default or event of default under any other
document or agreement securing or guaranteeing any of the obligations secured by
the Agreement; or the occurrence of any default or event of default with respect
to any material indebtedness of Debtor to any third party that causes such third
party to declare such indebtedness due prior to its scheduled date of maturity;
or

     (i) The occurrence of any default or event of default under or with respect
to any material obligation of Debtor to any affiliate of Secured Party (for the
purposes of this subparagraph, "affiliate" is defined as Hitachi Credit America
Corp. or any entity owned or controlled, directly or indirectly, by Hitachi
Credit America Corp.).

     4.  Remedies.

     (a) Upon the occurrence of any default under this Agreement, Secured Party
is authorized in its discretion to declare any or all of the indebtedness to be
immediately due and payable without demand or notice to Debtor, and may exercise
any one or more of the rights and remedies granted pursuant to this Agreement or
given to a secured party under applicable law, including without limitation the
Uniform Commercial Code, such rights and remedies to include without limitation
the right to take possession and sell, lease or otherwise dispose of the
Collateral.  If reasonable notice of any disposition of Collateral or other
enforcement is required, such requirement will be met if such notice is mailed,
postage pre-paid, to the address of Debtor shown below Debtor's signature on
this Agreement at least fifteen (15) days prior to the time of disposition or
other enforcement.  Debtor agrees that upon demand by Secured Party after
default, Debtor will promptly assemble the Collateral and make the Collateral
available to Secured Party at a place reasonably convenient to Secured Party.

     (b) Debtor agrees that all of the Collateral and all of the other security
which may be granted to Secured Party in connection with the obligations secured
hereby constitute equal security for all of the obligations secured hereby, and
agrees that Secured Party shall be entitled to sell, retain or otherwise deal
with any or all of the Collateral, in any order or simultaneously as Secured
Party shall determine in

Initial DV MF

                                       4
<PAGE>

its sole and absolute discretion, free of any requirement for the marshaling of
assets or other restriction upon Secured Party in dealing with the Collateral or
such other security.

     (c) Upon the occurrence and during the continuance of any default under
this Agreement, Debtor hereby irrevocably constitutes and appoints Secured Party
(and any employee or agent of Secured Party) as Debtor's true and lawful
attorney-in-fact with full power of substitution, in Secured Party's name or
Debtor's name or otherwise, for Secured Party's sole use and benefit, at
Debtor's cost and expense, to exercise the following powers with respect to the
Collateral:

          1.  To demand, sue for collection, receive, and give acquittance for
     any and all monies due or owing with respect to the Collateral;

          2.  To receive, take, endorse Debtor's name on, assign and deliver any
     checks, notes, drafts, documents or other instruments taken or received by
     Secured Party in connection with the Collateral;

          3.  To settle, compromise, prosecute, or defend any action or
     proceeding with respect to the Collateral;

          4.  To sell, transfer, assign or otherwise deal in or with the
     Collateral or the proceeds thereof, as fully as if Secured Party were the
     absolute owner thereof.

          5.  To sign Debtor's name to and file financing statements or such
     other documents and instruments as Secured Party may deem appropriate.

          6.  To take any and all action that Secured Party deems necessary or
     proper to preserve its interest in the Collateral, including without
     limitation, the payment of debts of Debtor that might impair the Collateral
     or Secured Party's security interest therein, the purchase of insurance on
     the Collateral, the repair or safeguard of the Collateral, or the payment
     of taxes thereon.

          7.  To notify account debtors of Secured Party's security interest in
     Debtor's accounts and to instruct them to make payment directly to Secured
     Party.

     (d) Debtor agrees that the powers of attorney granted herein are coupled
with an interest and shall be irrevocable until full, final and irrevocable
payment and performance of the indebtedness secured hereby; and that neither
Secured Party nor any officer, director, employee or agent of Secured Party
shall be liable for any act or omission, or for any mistake or error of
judgment, in connection with any such powers.

     (e) Notwithstanding the foregoing, Secured Party shall be under no duty to
exercise any such powers, or to collect any amount due on the Collateral, to
realize on the Collateral, to keep the Collateral, to make any presentment,
demand or notice of protest in connection with the Collateral, or to perform any
other act relating to the enforcement, collection or protection of the
Collateral.

     (f) This Agreement shall not prejudice the right of Secured Party at its
option to enforce the collection of any indebtedness secured hereby or any other
instrument executed in connection with this transaction, by suit or in any other
lawful manner.  No right or remedy is intended to be exclusive of any other
right or remedy, but every such right or remedy shall be cumulative to every
other right or remedy herein or conferred in any other agreement or document for
the benefit of Secured Party, or now or hereafter existing at law or in equity.

     5.  Miscellaneous.

     (a) This Agreement and the security interest in the Collateral created

finally and irrevocably paid and all other obligations of Debtor to Secured

Prior to such termination, this shall be a continuing agreement.

     (b) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF ILLINOIS IN ALL RESPECTS, INCLUDING MATTERS OF

     (d) This Agreement shall inure to the benefit of Secured Party, its
successors and assigns and to any other holder who derives from Secured Party
title to or an interest in the indebtedness which this Agreement secures, and
shall be binding upon Debtor, its successors and assigns.

     (e) In case any one or more of the provisions of this Agreement shall for
any reason be held to be invalid, illegal or unenforceable in any respect, such
invalidity, illegality or unenforceability shall not affect any other provision
hereof, but this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had not been included.

     (f) Any provision to the contrary notwithstanding contained herein or in
the Note or in any other instrument now or hereafter evidencing, securing or
otherwise relating to any secured indebtedness, neither Secured Party nor any
other holder of the secured indebtedness shall be entitled to receive or
collect, nor shall Debtor be obligated to pay, interest on any of the secured
indebtedness in excess of the maximum rate of interest at the particular time in
question, if any, which, under applicable law, may be charged to Debtor (herein
the "Maximum Rate"), provided that the Maximum Rate shall be automatically
increased or decreased, as the case may be, without notice to Debtor from time
to time as of the effective time of each change in the Maximum Rate, and if any
provision herein or in the Note or in such other instrument shall ever be
construed or held to permit the collection or to require the payment of any
amount of interest in excess of that permitted by applicable law, the provisions
of this paragraph shall control and shall override any contrary or inconsistent
provision herein or in the Note or in such other instrument.  The intention of
the parties being to conform strictly to the usury limitations under applicable
law, the Note, this Agreement, and each other instrument now or hereafter
evidencing or relating to any secured indebtedness shall be held subject to
reduction to the amount allowed under said applicable law as now or hereafter
construed by the courts having jurisdiction.

Dear Jim:

     This separation agreement ("Agreement") will confirm the agreement
between you and the Board of Trade of the City of Chicago ("Exchange") as
follows:

     1.   Separation from the Company

          By signing this agreement you acknowledge that your separation from
the Exchange will be effective on March 30, 2001 (the "Separation Date"). As of
the Separation Date, you will no longer be required to fulfill any of the duties
and responsibilities associated with your position.

     2.   Severance Payments

          The Exchange agrees to pay you the aggregate sum of $215,384.61 in
semi-monthly installments according to regular payroll practices, less
deductions required by law, commencing on the first scheduled payroll date to
occur following the date on which this Agreement becomes effective and
enforceable ("Severance Payments"). Such Severance Payments shall not be
considered compensation for purposes of any employee benefit plan, program,
policy or arrangement maintained or hereafter established by the Exchange or any
of its affiliates. You understand that the Severance Payments made to you
represent consideration for signing this Agreement and are not salary, wages or
benefits to which you were already entitled. You also acknowledge and represent
that you have already received everything to which you were entitled by virtue
of your employment relationship with the Exchange.

     3.   Release by You

     (a)  You (for yourself, your heirs, assigns or executors) release and
forever discharge the Exchange, any of its affiliates, and its and their
directors, officers, members, agents and employees from any and all claims,
suits, demands, causes of action, contracts, covenants, obligations, debts,
costs, expenses, attorney's fees, liabilities of whatever kind or nature in law
or equity, by statute or otherwise whether now known or unknown, vested or
contingent, suspected or unsuspected, and whether or not concealed or hidden,
which have existed or may have existed, or which do exist, through the date this
Agreement becomes effective and enforceable, ("Claims") of any kind, which
relate in any way to your employment with the Exchange or the termination of
that employment, except those arising out of the

performance of this Agreement, your rights under the employee benefit plans of
the Exchange and your rights to accrued, unused vacation and sick leave. Such
released Claims include, without in any way limiting the generality of the
foregoing language, any and all claims of employment discrimination under any
local, state, or federal law or ordinance, including, without limitation, Title
VII or the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991;
the Americans with Disabilities Act of 1990; the Age Discrimination in
Employment Act of 1967, as amended; or the Illinois Human Rights Act.

     (b)  In signing this Agreement you acknowledge that you intend that it
shall be effective as a bar to each and every one of the Claims herein above
mentioned or implied. You expressly consent that this Agreement shall be given
full force and effect according to each and all of its express terms and
provisions, including those relating to unknown and unsuspected Claims
(notwithstanding any state statute that expressly limits the effectiveness of a
general release of unknown, unsuspected and unanticipated Claims), if any, as
well as those relating to any other Claims herein above mentioned or implied.
You acknowledge and agree that this release is an essential and material term of
this Agreement and without such release the Exchange would not have made the
Severance Payments described in paragraph 2. You further agree that in the event
you bring your own Claim in which you seek damages against the Exchange or any
other released party, or in the event you seek to recover against the Exchange
or any other released party in any Claim brought by a governmental agency on
your behalf, this release shall serve as a complete defense to such Claims.

     (c)  By signing this Agreement, you acknowledge that you:

          (1)  have been given twenty-one days after receipt of this Agreement
               within which to consider it;

          (2)  have carefully read and fully understand all of the provisions of
               this Agreement;

          (3)  knowingly and voluntarily agree to all of the terms set forth in
               this Agreement;

          (4)  knowingly and voluntarily agree to be legally bound by this
               Agreement;

          (5)  have been advised and encouraged in writing (via this Agreement)
               to consult with an attorney prior to signing this Agreement;

          (6)  understand that this Agreement, including without limitation the
               release provisions, shall not become effective and enforceable
               until the eighth day following execution of this Agreement by
               you, and that at any time prior to the effective day you can
               revoke this Agreement.

     4.   Additional Agreements

          (a)  You also agree not to disparage the Exchange, or its past and
present investors, members, directors, officers or employees, and to keep all
confidential and proprietary information about the past or present business
affairs of the Exchange confidential unless a prior written release from the
Exchange is obtained. Your failure to comply with this provision will result in
termination of the Exchange's ongoing obligation to make the severance payments
hereunder.

          (b)  You further agree that as of the date hereof, you have returned
to the Exchange any and all property, tangible or intangible, relating to its
business, which you possessed or had control over at any time, including but not
limited to company-provided credit cards, building or office access cards, keys,
computer equipment, manuals, files, documents, records, software, customer
data base and other data, and that you shall not retain any copies,
compilations, extracts, excerpts, summaries or other notes of any such manuals,
files, documents, records, software, customer data base or other data.

     5.   Confidentiality of this Agreement

          The contents of this Agreement, including but not limited to its
financial terms, are strictly confidential. By signing this Agreement you, agree
and represent that you will maintain the confidential nature of the Agreement,
except (a) to legal counsel, tax and financial planners, and immediate family
who agree to keep it confidential; (b) as otherwise required by law, in which
case you shall notify the Exchange writing in advance of disclosure; and (c) as
necessary to enforce this Agreement.

          The Exchange agrees that it will keep the contents of this Agreement
confidential, except (a) to its executive staff and governing bodies, as
necessary or appropriate, and to its outside counsel and auditors; (b) as
otherwise required by law, regulation or in connection with our Registration
Statement on Form S-4 concerning our restructuring; and (c) as necessary to
enforce this Agreement.

     6.   No Transfer or Assignment

          You and the Exchange agree that no interest or right you have or any
of your beneficiaries has to receive payment or to receive benefits under this
Agreement shall be subject in any manner to sale, transfer, assignment, pledge,
attachment, garnishment, or other alienation or encumbrance of any kind, except
as required by law. Nor may such interest or right to receive payment or
distribution be taken, voluntarily or involuntarily, for the satisfaction of the
obligations or debts of, or other claims against you or your beneficiary,
including for alimony, except to the extent required by law.

     7.   No Admissions

wrongdoing either by the Exchange, its affiliates, or its and their directors,
officers, members, agents or employees.

     8.   No Other Agreement

          This Agreement contains the entire agreement between you and the
Exchange. No part of this Agreement may be changed except in writing, executed
by both you and the Exchange.

    9.    Governing Law

          This Agreement shall be interpreted in accordance with the laws of the
State of Illinois. Whenever possible, each provision of this Agreement shall be
interpreted in a manner as to be effective and valid under applicable law, but
if any provison shall be held to be prohibited or invalid under applicable law,
such provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating or affecting the remainder of such provision or
any of the remaining provisions of this Agreement.

     10.  Counterparts

          This Agreement may be executed in separate counterparts, each of
which is deemed to be an original and all of which taken together constitute
one and the same Agreement.

          Please indicate your agreement by signing this Agreement and returning

Very truly yours,

/s/ David J. Vitale
