    Addendum
      to Strategic Alliance Agreement

    

    This
      Addendum to the Strategic Alliance Agreement (‘addendum’) entered into between
Solanex
      Management Inc.,
      a
      Nevada corporation ("Solanex") and Eco
      Tech waste Management Systems Inc.,
      a
      British Columbia corporation ("EcoTech") originally dated 23rd
      day of May, 2006 (‘Agreement’)
      is entered into this 12th
      day of October, 2006.

    

    Preamble

    

    Solanex
      is a technology development company specializing in high temperature soil
      remediation for the resource industry. EcoTech is a development company that
      specializes in high temperature burner and gasifier systems and has a capability
      to manufacture a prototype high temperature gasifier. Solanex and Ecotech have
      jointly developed a portable Soil Remediation System for the remediation of
      soil
      contaminated by industrial use. In consideration for $2,000 to be paid to
      Ecotech, the parties agree to expand their business relationship to include
      a
      portable high temperature steam generation technology and jointly develop and
      market portable high temperature burner gasifier systems for use across North
      America.

    

    The
      steam
      generation technology is a natural off shoot from the original high temperature
      burner intended for use in soil remediation and is being developed for use
      in
      oil field situations where high-pressure
      steam is injected into the oil formation to soften the material in which the
      oil
      is trapped and help dilute and separate the oil from the earth. The steam
      injected under pressure also creates channels and cracks through which the
      oil
      can flow to the well. 

    

    To
      further this joint development, and in a spirit of good faith and mutual
      cooperation, the parties agree to abide by the terms, conditions and intent
      of
      their original Agreement dated May 23, 2006 and now to include the steam
      generation technology as well as the soil remediation burner.

    

    

    Accepted
      and Agreed to this 12th
      of October, 2006

be accompanied by accrued and unpaid interest thereon.

Section 2.6 Mandatory Principal Payments. On any day on which the aggregate
outstanding principal of the Loans exceeds the Borrowing Base or the Aggregate Commitment, such
excess shall be immediately due and payable without the necessity of any notice or demand.
Repayment of such excess amounts shall be applied to prepay the outstanding Loans, pro rata, and
shall be accompanied by accrued and unpaid interest thereon.

Section 2.7 Adjustments of Commitments.

Section 2.7.1 Adjustments by the Company. The Company may permanently reduce the
Aggregate Commitment, in whole or in part ratably among the Banks, in proportion to the amounts of
their respective Commitments in integral multiples of $1,000,000, upon at least ten Business Days’
written notice to Administrative Agent, which shall promptly provide a copy of such notice to each
Bank. Such notice shall specify the amount of any such reduction; provided,
however, that, subject to Sections 2.7.2, 11.9(b) and 11.9(c), the
amount of the Aggregate Commitment may not be reduced below the outstanding principal amount of the
Advance(s), and provided further that a reduction by the Company of the Aggregate
Commitment to zero shall terminate this Agreement as of the effective date of such reduction. All
accrued and unpaid commitment fees shall be payable on the effective date of such termination.

Section 2.7.2 Adjustments by Banks for Accelerated Termination. If the Commitment of
a Bank hereunder is terminated pursuant to Section 11.9(b) or 11.9(c), the Company
shall immediately notify Administrative Agent in writing of such termination (“Accelerated
Termination Notice”) and shall state the amount of such terminating Bank’s Commitment (“Terminated
Commitment”) in the Accelerated Termination Notice. Administrative Agent shall promptly provide a
copy of the Accelerated Termination Notice to each remaining Bank (each a “Non-Terminating Bank”).
Each Non-Terminating Bank shall notify the Company, in writing, on or before the fifth Business Day
after the date of the Accelerated Termination Notice, if and by what amount such Bank is willing to
increase its Commitment, which amount shall be equal to all or some portion of the Terminated
Commitment (each, a “2.7.2 Notice”). Any Non-Terminating Bank that fails to so notify the Company
on or before such fifth Business Day, shall be deemed to have declined to increase its Commitment.
If offers to increase Commitments are made by two or more Non-Terminating Banks in an aggregate
amount greater than the aggregate amount of the Terminated Commitment, such Non-Terminating Banks
and the Company hereby agree that such offers shall be allocated as nearly as possible in
proportion to the aggregate amount of such offers, so that the aggregate amount thereof will not
exceed the amount of the Terminated Commitment. On or before the 6th Business Day after the date
of the Accelerated Termination Notice, the Company shall notify Administrative Agent and each
Non-Terminating Bank of the amount by which each such Non-Terminating Bank’s Commitment has been
increased, which amount shall not exceed the amount of such Non-Terminating Bank’s offer to
increase its Commitment in such Bank’s 2.7.2 Notice. All increases of Commitments by the Banks
under this Section 2.7.2 shall become effective on the terminating Bank’s Accelerated
Termination Date (“2.7.2 Effective Date”). The Company shall promptly, and in no event later than
the 2.7.2 Effective Date, deliver to each Bank whose Commitment has been increased pursuant to this
Section 2.7.2 a new Note reflecting such Bank’s new Commitment amount and each such Bank
shall promptly, after repayment to such Bank of such Bank’s ratable share of all Advances
outstanding on the 2.7.2 Effective Date, return to the Company such Bank’s superseded Note. On the
2.7.2 Effective Date, the Commitments shall be adjusted to reflect any such increases.

Section 2.8 Commitment Fee. From the date hereof to and including the Revolving
Credit Termination Date, the Company agrees to pay to Administrative Agent for the ratable account
of the Banks a commitment fee of 7/100 of 1% per annum (on the basis of a year consisting of 360
days and for actual days elapsed) on the daily amount of such Bank’s ratable share (determined in
proportion to its respective Commitment) of the excess of (i) the amount of the Aggregate
Commitment over (ii) the aggregate principal amount of all outstanding Advances of the Banks,
payable in arrears on the last day of each November, February, May and August hereafter and on the
Revolving Credit Termination Date, commencing on the first of such dates to occur after the date
hereof.

Section 2.9 Collateral.

(a) All Obligations of the Company under this Agreement, the Notes and all other Loan
Documents shall be secured by the Collateral in accordance with the Collateral Documents.

(b) So long as no Default shall have occurred and be continuing, the Company may from time to
time replace any security credited to any Securities Account or any Money Fund Shares subject to
the Lien of the Security and Pledge Agreement with another security of a type described in CME Rule
816 or CME Rule 820 that has a market value equal to or greater than the market value of the
replaced security, determined as of the date of replacement by Collateral Agent in accordance with
its usual and customary practices.

(c) So long as no Default shall have occurred and be continuing, the Company may from time to
time direct Collateral Agent to (and Collateral Agent shall upon the request of the Company)
liquidate any securities credited to any Securities Account and any Money Fund Shares and apply the
proceeds thereof and any other amounts credited to any Securities Account to repay any outstanding
Loans, provided that after giving effect to such liquidation and the repayment of such
Loans, the aggregate principal amount of all remaining Loans outstanding as of the date of such
removal shall not exceed the Borrowing Base as of the date of such removal.

(d) Upon any replacement or liquidation of Collateral pursuant to subsection (b) or
(c) above, the Lien of Collateral Agent on the replaced or liquidated Collateral, as
applicable, shall be deemed released without further consent of Collateral Agent or any Bank.

Section 2.10 Additional Credit Facility.

(a) The Company may, at its option and without the consent of the Banks, in a minimum amount
of $50,000,000 on each occasion, seek to increase the Aggregate Commitment by up to an aggregate
amount of $200,000,000 (resulting in a maximum Aggregate Commitment of $1,000,000,000) upon at
least three (3) Business Days’ prior written notice to Administrative Agent and Collateral Agent,
which notice shall specify the amount of any such increase and shall be delivered at a time when no
Default or Unmatured Default has occurred and is continuing. The Company may, after giving such
notice and in its sole discretion, offer the increase in the Aggregate Commitment to other lenders
or entities reasonably acceptable to Administrative Agent and the Company. No increase in the
Aggregate Commitment shall become effective until the existing or new Banks extending such new or
increased Commitment amount and the Company shall have delivered to Administrative Agent a document
reasonably satisfactory to Administrative Agent and the Company pursuant to which any such existing
Bank states the amount of its Commitment increase, any such new Bank states its Commitment amount
and agrees to assume and accept the obligations and rights of a Bank hereunder and the Company
accepts such new or increased Commitments. The Banks (new or existing) shall accept an assignment
from the existing Banks, and the existing Banks shall make an assignment to the new or existing
Banks accepting a new or increased Commitment, of a direct interest in each then outstanding
Advance such that, after giving effect thereto, all credit exposure hereunder is held ratably by
the Banks in proportion to their respective Commitments. Assignments pursuant to the preceding
sentence shall be made in exchange for the principal amount assigned plus accrued and unpaid
interest and accrued and unpaid facility fees. Any such increase of the Aggregate Commitment
shall be subject to receipt by Administrative Agent from the Company of such supplemental opinions,
resolutions, certificates and other documents as Administrative Agent may reasonably request.

(b) In addition to the foregoing, to the extent that the Company has reduced the Aggregate
Commitment with respect to any or all of the Banks, the Company may, from time to time, increase
any portion of any such Bank’s respective Commitment, with such Bank’s consent, in an amount up to
the amount so reduced, provided that each such Bank shall accept an assignment from the
existing Banks, and the existing Banks shall make an assignment to each such Bank of a direct
interest in each then outstanding Advance such that, after giving effect thereto, all credit
exposure hereunder is held ratably by the Banks in proportion to their respective Commitments. The
documents evidencing any such increase in the Commitment shall be in a form reasonably acceptable
to the Company and Administrative Agent.

(c) This Section 2.10 shall supercede any provisions contained in this Agreement to
the contrary.

ARTICLE III

FUNDING THE CREDITS

Section 3.1 Method of Borrowing. The Company shall give Administrative Agent and
Collateral Agent notice not later than 3:45 p.m. (Chicago time) on the Borrowing Date of each
Advance, specifying the amount of such Advance. Subject to Section 4.1 and the
satisfaction of the applicable conditions precedent set forth in Article V, each Bank
severally shall make available to Administrative Agent, in the specified account located at
Administrative Agent, its pro rata share of the full amount of each Advance in immediately
available funds. Following the receipt of a notice of Advance from the Company, Collateral Agent
shall determine the aggregate market value of the Collateral and the Borrowing Base in accordance
with the terms hereof and promptly, but in any event, not later than 4:15 p.m. (Chicago time),
provide the Company, Administrative Agent and each Bank with a Collateral Notice. Upon
determination of the Borrowing Base, Administrative Agent shall make available to the Company, not
later than 4:45 p.m. (Chicago time) on the Borrowing Date, in immediately available funds the
lesser of (a) the aggregate amount of each Bank’s pro rata share of the Advance to the extent such
amount has been funded by such Bank at such time or (b) the Excess Availability.

Section 3.2 Minimum Amount of Each Advance. Except in the case of a Test Draw, each
Advance shall be in the minimum amount of $10,000,000 (and in integral multiples of $250,000 if in
excess thereof), provided, however, that any Advance may be in the aggregate amount
of the Excess Availability.

Section 3.3 Rate Before and After Maturity. Prior to maturity, Advances shall bear
interest at the Fed Funds Target Rate plus 45/100 of 1% per annum. Any Advance not paid at
maturity, whether by acceleration or otherwise, shall bear interest until paid in full at a rate
per annum equal to the Fed Funds Target Rate plus 2.4% per annum. In the event that a change in
the Fed Funds Target Rate is announced or published at the time a Loan is outstanding, such change
shall become effective at the time it is announced or published.

Section 3.4 Method of Payment. All payments (including prepayments) of principal,
interest, commitment fees and other amounts payable hereunder by the Company shall be made without
setoff or counterclaim in immediately available funds to Administrative Agent, for the benefit of
the Banks, at the address specified pursuant to Article XIII. All such payments shall be
applied to principal, interest, fees, expenses and other amounts due and payable hereunder in the
following order: first, to amounts payable hereunder other than principal, interest and commitment
fees; second, to commitment fees (in chronological order in accordance with the dates such fees
became due and payable); and third, to principal of, and interest on, the Advances (in
chronological order in accordance with the dates such Advances were made; and as to any single
Advance, first to interest thereon and second to principal thereof). Subject to the provisions of
Section 4.4 and, except with respect to payments made to a Bank whose Commitment is
terminated (or whose commitment fee is revised) pursuant to Section 11.9(b) or (c),
(a) all payments of principal of, and interest on, the Advances shall be made by Administrative
Agent to the Banks ratably among the Banks, in proportion to the outstanding principal amount of
their respective Loans constituting part of such Advance and (b) all payments of commitment fees
and other amounts payable hereunder by Administrative Agent to the Banks shall be made to the Banks
ratably among the Banks, in proportion to the amounts of their respective Commitments on the date
such payment is made.

Section 3.5 Notes; Telephonic Notices.(a) Each Bank shall maintain in accordance with
its usual and customary practices an account or accounts evidencing the Loans made by such Bank
from time to time, including the amounts of principal and interest payable and paid to such Bank
from time to time under this Agreement and the Notes; and each Bank is hereby authorized to record
the principal amount of each of its Loans and each repayment on the schedule attached to its Note
or in its books and records; provided, however, that the failure to so record shall
not affect the Company’s obligations under such Note. Administrative Agent shall also maintain
accounts in which it will record (i) the amount of each Loan made hereunder, (ii) the amount of any
principal or interest due and payable or to become due and payable from the Company to each Bank
hereunder and (iii) the amount of any sum received by Administrative Agent hereunder from the
Company and each Bank’s share thereof. The entries maintained in the accounts maintained by the
Banks and Administrative Agent pursuant to this Section shall be prima facie evidence of the
existence and amounts of the Obligations therein recorded; provided, however, that
the failure of Administrative Agent or any Bank to maintain such accounts or any error therein
shall not in any manner affect the obligation of the Company to repay the Loans in accordance with
their terms. In the event the records maintained by a Bank conflict with the records maintained by
Administrative Agent, the records maintained by Administrative Agent shall control.

(b) The Company hereby authorizes the Banks and Administrative Agent to extend Advances based
on telephonic notices made by any Persons any such Bank or Administrative Agent in good faith
believes to be acting on behalf of the Company. The Company agrees to deliver promptly to
Administrative Agent a written confirmation of each telephonic notice signed by an authorized
signatory. If the written confirmation differs in any material respect from the action taken by
Administrative Agent, the records of Administrative Agent shall govern absent manifest error.

Section 3.6 Interest Payment Dates; Interest Basis. Interest accrued on each Advance
prior to maturity shall be payable to Administrative Agent for the benefit of the Banks on the date
on which the Advance is paid or prepaid, whether due to acceleration or otherwise. Interest
accrued on each Advance after maturity shall be payable on demand. Interest and commitment fees
shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be
payable for the day an Advance is made but not for the day of any payment on the amount paid if
payment is received prior to noon (local time at the place of payment). If any payment of
principal of, or interest on, an Advance shall become due on a day which is not a Business Day,
such payment shall be made on the next succeeding Business Day and, in the case of a principal
payment, such extension of time shall be included in computing interest in connection with such
payment.

ARTICLE IV

ADMINISTRATIVE AGENT

Section 4.1 Notice to and Payment by the Banks. Promptly after receiving notice from
the Company of each Advance requested pursuant to Section 3.1, Administrative Agent shall
notify each of the applicable Banks by telephone (which may, at the option of Administrative Agent,
be accompanied by facsimile transmission), of each Advance, which notice shall state: (a) the
dollar amount of such Advance; (b) each Bank’s ratable share of such Advance; (c) the date and time
when such Advance is to be made; and (d) the account located at Administrative Agent to which the
applicable Bank’s ratable share of such Advance shall be sent. Except as hereinafter provided,
promptly after receipt of such notice from Administrative Agent and, in any event, before the time
specified in such notice as the time when such Advance is to be made to the Company, each
applicable Bank shall transfer its ratable share of such Advance to Administrative Agent by Federal
Reserve wire transfer or, in the event of a failure of the Federal Reserve wire transfer system, in
other immediately available funds via the SWIFT system or otherwise.

Section 4.2 Payment by Banks to Administrative Agent.(a) Unless Administrative Agent
shall have been notified by a Bank prior to the date on which such Bank is scheduled to make
payment to Administrative Agent of the proceeds of a Loan (which notice shall be effective upon
receipt) that such Bank does not intend to make such payment, Administrative Agent may assume that
such Bank has made such payment when due and Administrative Agent may in reliance upon such
assumption (but shall not be required to) make available to the Company the proceeds of the Loan to
be made by such Bank and, if any Bank has not in fact made such payment to Administrative Agent,
such Bank shall, on demand, pay to Administrative Agent the amount made available to the Company
attributable to such Bank together with interest thereon in respect of each day during the period
commencing on the date such amount was made available to the Company and ending on (but excluding)
the date such Bank pays such amount to Administrative Agent at a rate per annum equal to: (i) from
the date the related advance was made by Administrative Agent to the date two (2) Business Days
after payment by such Bank is due hereunder, the Federal Funds Target Rate for each such day and
(ii) from the date two (2) Business Days after the date such payment is due from such Bank to the
date such payment is made by such Bank, the Federal Funds Target Rate in effect for each such day
plus 2.4%. If such amount is not received from such Bank by Administrative Agent immediately upon
demand, the Company will, on demand, repay to Administrative Agent the proceeds of the Loan
attributable to such Bank with interest thereon at a rate per annum equal to the interest rate
applicable to the relevant Loan.

(b) The failure of any Bank to make a payment to Administrative Agent of the proceeds of the
Loan to be made by such Bank shall not relieve any other Bank of its obligation hereunder to make
payment to Administrative Agent of the proceeds of a Loan, but no Bank shall be responsible for the
failure of any other Bank to make the payment required to be made by such other Bank.

Section 4.3 Distribution of Payments. Whenever Administrative Agent receives from, or
on behalf of the Company, or any other person or party, a payment of principal, interest or
commitment fees or other amount payable in connection with the Loans with respect to any of which
the applicable Banks are entitled to receive a share, Administrative Agent shall promptly pay to
such Banks, in lawful money of the United States of America and in the kind of funds so received by
Administrative Agent, the amount due each of such Banks as determined pursuant to this Agreement;
provided, however, that the amount of such distribution shall be adjusted to the
extent that amounts are owed by any Bank to Administrative Agent pursuant to Section 4.2 or
are required to be returned to Administrative Agent pursuant to Section 4.4. If any
payment of principal, interest or commitment fees or other amount payable in connection with the
Loans is received from or on behalf of the Company by Administrative Agent before 10:00 a.m.
(Chicago time) on any Business Day, Administrative Agent shall use reasonable efforts to wire
transfer the appropriate portion of the same to the applicable Banks that same Business Day, but in
any event shall wire the same to each of such Banks before the end of the next Business Day. In
the event that Administrative Agent receives any such payment from or on behalf of the Company
before 10:00 a.m. (Chicago time) on any Business Day and does not transfer to the applicable Banks
the appropriate portion of such payment on that day, the Company shall, promptly upon receipt of
notice from any such Bank, pay directly to such Bank an amount equal to the interest on such
portion, at the Fed Funds Target Rate or, with respect to any payment of principal on a Loan, at
the rate set forth in Section 3.3, for the period commencing on the day Administrative
Agent receives such payment up to but not including the following Business Day.

Section 4.4 Rescission of Payments by the Company. If all or part of any payment made
by the Company to Administrative Agent of principal, interest or commitment fees or other amount
payable in connection with the Loans is rescinded or must otherwise be returned for any reason and
if Administrative Agent has paid to any of the Banks such Bank’s ratable share therein, such Bank
shall, upon telephone notice from Administrative Agent, forthwith pay to Administrative Agent, on
the date of such telephone notice (if notice is received by Administrative Agent at or prior to
10:00 a.m. Chicago time) or on the next Business Day (if notice is received by Administrative Agent
after 10:00 a.m. Chicago time), an amount equal to such Bank’s ratable interest in the amount that
was rescinded or that must be so returned by Administrative Agent. Administrative Agent shall
promptly return to the Company, or to whomever shall be legally entitled thereto pursuant to an
order of a court of competent jurisdiction, each such amount (or any lesser amount) that is
received from each Bank. Administrative Agent shall have no obligation to the Company for any
amount that Administrative Agent paid to any Bank and that is not repaid by such Bank,
provided that Administrative Agent did in fact provide such Bank with the notice described
above to the effect that such payment was rescinded or must be returned.

Section 4.5 Powers Granted to Administrative Agent.(a) The Company and one or more
Banks (each a “Principal Bank”) may, upon mutual agreement, from time to time request another Bank
to act as an additional agent for the purpose of administering and servicing the Loans of the
Principal Banks. Upon the acceptance of the offer to service by the proposed additional agent
(which shall be in the sole discretion of such proposed administrative agent), such Bank shall be
an additional agent (“Additional Agent”) hereunder and as administrator of the Loans of the
Principal Banks for which it acts (and not as an agent, employee or fiduciary), shall be entitled
to exercise all such powers as are incidental to the powers to receive and collect funds from the
Principal Banks and the Company as provided for in this Agreement, and to take such other actions
with respect to such Loans as are provided hereby or as may be from time to time agreed by such
Additional Agent and the Principal Banks. In acting under this Agreement, Additional Agent agrees
to exercise the same degree of care in administering such Loans as it would use in managing its own
loans; provided, however, that this sentence shall not make Additional Agent a
fiduciary to any Principal Bank. The Principal Banks and the Company hereby agree and acknowledge
that (i) in performing the duties provided for in this Agreement, Additional Agent is acting solely
for the benefit of the Principal Banks and are in no way to be construed to be acting as agent for
the Company; and (ii) the servicing arrangement provided for herein is not intended to constitute,
and shall not be construed to establish, a partnership or joint venture between Additional Agent
and the Principal Banks, or between Additional Agent and the Company.

(b) The Company shall promptly notify Administrative Agent of the appointment of an Additional
Agent. To the extent an Additional Agent will perform any function or duty currently performed by
Administrative Agent, Administrative Agent shall cease its performance of such function or duty
when the Company directs Administrative Agent to cease such performance. An Additional Agent shall
not be deemed an agent or fiduciary of Administrative Agent.

ARTICLE VI

REPRESENTATIONS AND WARRANTIES

The Company represents and warrants to the Banks, as of the date hereof and the date of each
Advance, that:

Section 6.1 Corporate Existence and Standing. Each of the Company and the
Subsidiaries is a corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation and has all requisite authority to conduct its business
in each jurisdiction in which its business is conducted and where the failure to have such
authority would reasonably be expected to have a Material Adverse Effect.

Section 6.2 Authorization and Validity.

(a) The Company has the corporate power and authority and legal right to execute and deliver
the Loan Documents and to perform its obligations thereunder. The execution and delivery by the
Company of the Loan Documents and the performance of its obligations thereunder have been duly
authorized by proper corporate proceedings. The Company has duly executed and delivered the Loan
Documents, and the Loan Documents constitute legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, except as enforceability may be
limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights
generally and by general principles of equity (whether enforcement is considered in a proceeding at
law or in equity).

(b) The Company has the authority pursuant to CME Rules 816, 817 and 820 to execute and
deliver, as Member Attorney-in-Fact on behalf of the applicable Clearing Members, the Collateral
Documents. Pursuant to CME Rule 817, the Company has the authority, as Member Attorney-in-Fact on
behalf of the applicable Clearing Members, to cause the Security Deposits to be subject to the Lien
of the Collateral Documents to secure the Obligations. Pursuant to CME Rule 817, the Company has
the authority, as Member Attorney-in-Fact on behalf of the applicable Clearing Members, to cause
the Performance Bonds of Defaulted Clearing Members to be subject to the Lien of the Collateral
Documents to secure the Obligations. CME Rules 816, 817, 820 and 913.B, as set forth in
Exhibit J, have been duly adopted and are in full force and effect.

Section 6.3 Compliance with Laws and Contracts. Neither the execution and delivery by
the Company of the Loan Documents, nor the consummation of the transactions therein contemplated,
nor compliance with the provisions thereof will violate any law, rule, regulation, order, writ,
judgment, injunction, decree or award binding on the Company or any Subsidiary or the Company’s or
any Subsidiary’s articles of incorporation or by-laws or the provisions of any material indenture,
instrument or agreement to which the Company or any Subsidiary is a party or is subject, or by
which it, or its property, is bound, or conflict with or constitute a default thereunder. No
order, consent, approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, any governmental or public body or authority, or any
subdivision thereof, that has not been obtained is required to authorize, or is required in
connection with the execution, delivery and performance of, or the legality, validity, binding
effect or enforceability of, any of the Loan Documents as against the Company.

Section 6.4 Financial Statements. The most recent annual, audited consolidated
financial statements of Holdings and its subsidiaries (which include the Company and the
Subsidiaries) heretofore delivered to the Banks were prepared in accordance with generally accepted
accounting principles in effect on the date such statements were prepared and fairly present in all
material respects the consolidated financial condition and operations of Holdings and its
subsidiaries at such date and the consolidated results of their operations for the period covered
thereby.

Section 6.5 Material Adverse Change. No material adverse change in the business,
financial condition, or results of operations of the Company and the Subsidiaries has occurred
since the date of the financial statements referred to in Section 6.4; provided,
however, that in the event the Company utilizes its own funds to repay all or any portion
of an Advance, and such repayment results in such a material adverse change, then such material
adverse change shall not be deemed to have occurred until the thirty-first consecutive day that
such material adverse change continues.

Section 6.6 Subsidiaries. Schedule I contains an accurate list of all of the
presently existing Subsidiaries of the Company, setting forth their respective jurisdictions of
incorporation and the percentage of their respective capital stock owned by the Company or other
Subsidiaries. All of the issued and outstanding shares of capital stock of such Subsidiaries have
been duly authorized and issued and are fully paid and non-assessable.

Section 6.7 Accuracy of Information. No written information, exhibit or report
furnished by the Company or any Subsidiary to any Bank in connection with the negotiation of the
Loan Documents contained any material misstatement of fact or omitted to state a material fact or
any fact necessary to make the statements contained therein not materially misleading in light of
the circumstances existing at the time furnished.

Section 6.8 Margin Regulations. Margin Stock (as defined in Regulation U) constitutes
less than 25% of those assets of the Company and its Subsidiaries which are subject to any
limitation on sale, pledge, or other restriction hereunder. No proceeds of any Loans will be used
to “purchase” or “carry” any “margin stock” (each as defined in Regulation U), or for any purpose
that violates the provisions of Regulation T, U or X of the Board of Governors of the Federal
Reserve System as now and from time to time hereafter in effect.

Section 6.9 Taxes. The Company and its Subsidiaries have filed all United States

them and have paid all taxes due pursuant to said returns or pursuant to any assessment received by
the Company or any such Subsidiary, except such taxes, if any, as are being contested in good
faith. To the best of the Company’s knowledge, no tax liens have been filed and no claims are
being asserted with respect to any such taxes other than those taxes that are being contested in
good faith. The charges, accruals and reserves on the books of the Company and its Subsidiaries in

obligations under the Loan Documents.

Section 6.11 ERISA. Each Plan complies in all material respects with all applicable
requirements of law and regulations, no Reportable Event has occurred with respect to any Plan,

(h) Such other information (including non-financial information) as any Bank may from time to
time reasonably request.

Section 7.2 Use of Proceeds. Except in the case of a Test Draw, the Company will only
use the proceeds of the Advances to provide temporary liquidity in circumstances where CME is
entitled to use the Security Deposits and Performance Bonds of its Clearing Members to satisfy any
outstanding obligations of any defaulting Clearing Members to CME as provided in the CME Rules and
in circumstances where a Money Gridlock Situation that affects the Company’s operations exists.
Additionally, the Company may use the proceeds of the Advances to fulfill its obligations under the
GFXTM Guaranty, provided, however, that the Company may use the proceeds for such
purposes only up to the amount of Surplus Funds on any given day. Additionally, the Company from
time to time may conduct Test Draws which may be repaid on the Borrowing Date or on the Business
Day immediately following such Borrowing Date. The Company will not, nor will it permit any
Subsidiary to, use any of the proceeds of the Loans to “purchase” or “carry” any “margin stock”
(each as defined in Regulation U) or for any purpose that violates the provisions of Regulation T,
U or X of the Board of the Federal Reserve System as now and from time to time hereafter in effect.

Section 7.3 Notice of Default. The Company will, and will cause each Subsidiary to,
give prompt notice in writing to the Banks of the occurrence of any Default or Unmatured Default
and of any other development, financial or otherwise, which would reasonably be expected to
materially adversely affect its business, properties or affairs or the ability of the Company to
repay the Obligations.

Section 7.4 Conduct of Business. The Company will, and will cause each Subsidiary to,
carry on and conduct its business in substantially the same manner and in substantially the same
fields of enterprise as it is presently conducted and to do all things necessary to remain duly
incorporated, validly existing and in good standing as a domestic corporation in its jurisdiction
of incorporation and maintain all requisite authority to conduct its business in each jurisdiction
in which its business is conducted and where the failure to have such authority would reasonably be
expected to have a Material Adverse Effect.

Section 7.5 Compliance with Laws. The Company will, and will cause each Subsidiary
to, comply with all laws, rules, regulations, orders, writs, judgments, injunctions, decrees or
awards to which it may be subject, except where the failure to so comply would not reasonably be
expected to have a Material Adverse Effect.

Section 7.6 Inspection. The Company will, and will cause each Subsidiary to, permit
Administrative Agent and Collateral Agent or its representatives and agents, to inspect any of the
properties, corporate books and financial records of the Company and each Subsidiary, to examine
and make copies of the books of accounts and other financial records of the Company and each
Subsidiary, and to discuss the affairs, finances and accounts of the Company and each Subsidiary
(the foregoing activities, an “Audit”) with, and to be advised as to the same by, their respective
officers at such reasonable times and intervals as Administrative Agent may designate;
provided that so long as no Default has occurred and is continuing the Company shall only
be responsible for the costs and expenses of one Audit per 12-month period.

Section 7.7 Tangible Net Worth. The Company will maintain at all times a Consolidated
Tangible Net Worth of not less than $96,000,000. In the event that the Company exercises its right
to increase the Aggregate Commitment under Section 2.10(a), the minimum Consolidated
Tangible Net Worth that the Company will maintain will increase on a ratable basis to the increase
in the Aggregate Commitment such that if the Company increases the Aggregate Commitment by
$200,000,000 (resulting in a maximum Aggregate Commitment of $1,000,000,000), the minimum
Consolidated Tangible Net Worth to be maintained by the Company would increase by $24,000,000 to
$120,000,000. If the Company exercises its rights to decrease the Aggregate Commitment under this
Agreement, the minimum Consolidated Tangible Net Worth to be maintained by the Company will
decrease on a ratable basis, provided, however, that under no circumstances will
the minimum Consolidated Tangible Net Worth be reduced to less than $90,000,000. Any such ratable
increase or decrease in the Company’s maintenance of the Consolidated Tangible Net Worth shall be
effective immediately upon the related increase or decrease in the Aggregate Commitment in
accordance with the terms of this Agreement.

Section 7.8 Liens. The Company will not, nor will it permit any Subsidiary to, create
or incur any Lien in, of or on the Collateral, except:

(a) Liens in favor of Collateral Agent.

(b) Liens in favor of the Company, which Liens are subordinated to the Liens in favor of
Collateral Agent in accordance with Article XV hereof.

(c) Liens arising out of repurchase agreements or reverse repurchase agreements entered into
by the Company or any Subsidiary.

(d) Liens arising out of judgments or awards against the Company or any Subsidiary, in an
amount of not more than $5,000,000 in the aggregate, which judgment or award is vacated,
discharged, satisfied or stayed or bonded pending appeal within 60 days from the entry thereof.

Section 7.9 Additional Clearing Members. Promptly upon any Person becoming a Clearing
Member of CME, the Company will execute and deliver, as Member Attorney-in-Fact, a supplement to
the Security and Pledge Agreement, substantially in the form of Exhibit A thereto, joining such
Clearing Member as a party to the Security and Pledge Agreement and a supplement to the Securities
Account Control Agreement, substantially in the form of Exhibit B thereto, joining such Clearing
Member as a party to the Securities Account Control Agreement. If such new Clearing Member
deposits Money Fund Shares in satisfaction of their Security Deposit requirement to the extent such
Money Fund Shares are included in the Borrowing Base, the Company will execute and deliver, as
Member Attorney-in-Fact, a Money Fund Control Agreement, substantially in the form of Exhibit C to
the Security and Pledge Agreement with respect to such Money Fund Shares for the purpose of
granting to Collateral Agent control (within the meaning of the UCC) of the Money Fund Shares
subject thereto.

Section 7.10 CME Rule Changes. The Company will not, without the prior written
consent of the Banks, amend, revoke, or rescind any CME Rule in any manner that would have a
materially adverse effect on the Lien granted to Collateral Agent in the Collateral or the ability
of Collateral Agent to enforce any of its rights under the Collateral Documents.

Section 7.11 Taxes. The Company will, and will cause each Subsidiary to, pay when due
all taxes, assessments and governmental charges and levies upon it or its income, profits or
property, except those (i) which are being contested in good faith by appropriate proceedings and
with respect to which adequate reserves have been set aside on the books of the Company or such
Subsidiary, as applicable, or (ii) as to which the failure to pay would not reasonably be expected
to have a Material Adverse Effect.

Section 7.12 Insurance. The Company will, and will cause each Subsidiary to, maintain
with financially sound and reputable insurance companies insurance on all their property in such
amounts and covering such risks as is consistent with sound business practice in the industry, and
the Company will furnish to Administrative Agent upon request of any Bank full information as to
the insurance carried. Administrative Agent shall furnish such information to each Bank.

ARTICLE IX

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

Section 9.1 Acceleration. If any Default described in Section 8.6 or
8.7 occurs, the obligations of the Banks to make Loans hereunder shall automatically
terminate and the Obligations shall immediately become due and payable without any election or
action on the part of any Bank. If any other Default occurs, Administrative Agent may, or upon the
direction of the Required Banks shall, terminate or suspend the Commitments of the Banks to make
Loans hereunder, or declare the Obligations to be due and payable, or both, whereupon such
Obligations shall become immediately due and payable, without presentment, demand, protest or
notice of any kind, all of which the Company hereby expressly waives. In addition, at any time
after which the Obligations have become due and payable and the obligations of the Banks to make
Loans hereunder have terminated in accordance with this Section 9.1, Collateral Agent may,
with the consent of the Required Banks (or shall, upon the direction of the Required Banks),
enforce any and all rights and interest created under the Collateral Documents or the UCC,
including, without limitation, foreclosing the security interests created pursuant to the
Collateral Documents by any available judicial procedure, and exercise all other rights and
remedies of Collateral Agent otherwise available under any other provision of this Agreement, by
operation of law, at equity or otherwise, all of which are hereby expressly preserved and all of
which rights shall be cumulative.

Section 9.2 Amendments. Subject to the provisions of this Section 9.2, the
Required Banks and the Company may enter into agreements supplemental hereto for the purpose of
adding or modifying any provisions to the Loan Documents or changing in any manner the rights of
the Banks or the Company hereunder or waiving any Default hereunder; provided,
however, that:

(a) the consent of the Company and all of the Banks shall be required to (i) reduce the
percentage specified in the definition of Required Banks, (ii) reduce the principal amount of or
extend the maturity date for any Advance or reduce the rate or change the time of payment of
interest thereon, (iii) reduce the rate or change the time of payment of any commitment fee, (iv)
adjust the amount of the Commitment of any Bank except as otherwise permitted herein, (v) amend
Section 2.7, 2.8, 5.2 or this Section 9.2, (vi) extend the
Revolving Credit Termination Date, (vii) permit the Company to assign its rights under this
Agreement, (viii) amend the definition of “Borrowing Base” or “Discounted Value” or the provisions
of Annex I hereto (except as set forth in clause (c) below) or (ix) release any of the
Collateral from the Lien granted pursuant to the Collateral Documents other than as permitted by
this Agreement or any other Loan Document;

(b) the Company may add a new Bank(s) under the terms of this Agreement, provided,
however, that each such new Bank shall agree in writing to be bound by the terms of this
Agreement;

(c) the Company may modify the Concentration Policy or Minimum Credit Rating, each as set
forth on Annex I hereto, at any time, if such modification results in an imposition of a
more restrictive Concentration Policy or Minimum Credit Rating than that set forth on Annex
I. The Company may modify the Concentration Policy or Minimum Credit Rating upon approval of
the Required Banks if such modification results in the imposition of a less restrictive
Concentration Policy or Minimum Credit Rating than that set forth on Annex I; and

(d) any amendment, modification or waiver of any provision of any Loan Documents that affects
the rights or obligations of an Agent shall not be effective without such Agent’s prior written
consent.

Section 9.3 Preservation of Rights. No delay or omission of the Banks to exercise any
right under the Loan Documents shall impair such right or be construed to be a waiver of any
Default or an acquiescence therein, and the making of a Loan notwithstanding the existence of a
Default or the inability of the Company to satisfy the conditions precedent to such Loan shall not
constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right, and no waiver,
amendment or other variation of the terms, conditions or provisions of the Loan Documents
whatsoever shall be valid unless in writing signed by the Banks required pursuant to Section
9.2, and then only to the extent in such writing specifically set forth. All remedies
contained in the Loan Documents or by law afforded shall be cumulative and all shall be available
to the Banks until the Obligations have been paid in full and the Commitments have been terminated.

ARTICLE X

THE AGENTS

Section 10.1 Declaration and Acceptance of Appointment; No Fiduciary Duties. Subject
to the terms and conditions hereof, each Bank hereby appoints and authorizes Bank of Montreal as
its administrative agent hereunder and under the other Loan Documents and The Bank of New York to
act as its collateral agent hereunder and under each of the Collateral Documents and other Loan
Documents, each with such powers as are expressly delegated to each Agent by the terms of this
Agreement, the Collateral Documents, and the other Loan Documents, together with such other powers
as are reasonably incidental thereto. Each of Bank of Montreal and The Bank of New York, by its
execution hereof, hereby accepts the appointment made under this Section 10.1. Neither
Administrative Agent nor Collateral Agent shall have any duties or responsibilities except those
expressly set forth in this Agreement, the Collateral Documents and the other Loan Documents, or be
a trustee for, or have any fiduciary obligation to, any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities on the part of either Administrative Agent or
Collateral Agent shall be read into this Agreement or any other Loan Document or otherwise exist
for such Agent. In performing its functions and duties hereunder and under the other Loan
Documents, Administrative Agent and Collateral Agent shall act solely as agents for the Banks and
do not assume nor shall be deemed to have assumed any obligation or relationship of trust or agency
with or for the Company or any of its successors or assigns. Neither Administrative Agent nor
Collateral Agent shall be required to take any action that exposes such Agent to personal liability
or that is contrary to this Agreement, any other Loan Document or applicable law. The appointment
and authority of each Agent hereunder shall terminate upon the indefeasible payment in full of all
Obligations and the termination of the Commitments. Each Bank hereby authorizes Collateral Agent
to execute each of the Collateral Documents on behalf of such Bank (the terms of which shall be
binding on such Bank).

Section 10.2 Reliance by Each Agent. Each Agent shall in all cases be entitled to
rely, and shall be fully protected in relying, upon any document or conversation believed by it in
good faith to be genuine and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without limitation, counsel to
the Company), independent accountants and other experts selected by such Agent and acceptable to
the Required Banks. Each Agent shall in all cases be fully justified in failing or refusing to
take any action under this Agreement or any other Loan Document unless it shall first receive
advice or concurrence of the Company or the Required Banks (or, if required, all of the Banks), as
applicable, as it deems appropriate and it shall first be indemnified to its satisfaction by the
Banks, provided that unless and until such Agent shall have received such advice, such
Agent may take or refrain from taking any action, as such Agent shall deem advisable and in the
best interests of the Banks. Each Agent shall in all cases be fully protected in acting, or in
refraining from acting, in accordance with a request of the Company or the Required Banks or all of
the Banks, as applicable, and such request and any action taken or failure to act pursuant thereto
shall be binding upon all the Banks.

Section 10.3 Reimbursement and Indemnification. The Banks severally agree to
reimburse and indemnify each Agent and its officers, directors, employees, representatives and
agents ratably in proportion to the amounts of their respective Commitments, to the extent not paid
or reimbursed by the Company (i) for any amounts for which such Agent, acting in its capacity as
Agent, is entitled to reimbursement by the Company hereunder or under any other Loan Document and
(ii) for any other actual out-of-pocket expenses incurred by such Agent, in its capacity as Agent
and acting on behalf of the Banks, in connection with the administration and enforcement of this
Agreement and the other Loan Documents, except in each case, for any amounts or expenses that arise
as a result of the gross negligence or willful misconduct of such Agent.

Section 10.4 Each Agent in its Individual Capacity. Each Agent and its affiliates may
make loans to, accept deposits from and generally engage in any kind of business with the Company
or any affiliate of the Company as though such Agent were not an Agent hereunder. With respect to
the making of Loans pursuant to this Agreement, each Agent shall have the same rights and powers
under this Agreement in its individual capacity as any Bank and may exercise the same as though it
were not an Agent, and the terms “Bank,” and “Banks” shall include each Agent in its individual
capacity.

Section 10.5 Resignation or Termination of Agent(a) . Any Agent may resign its
position as such at any time upon ninety (90) days’ prior notice to the Company, the other Agent
and the Banks. Any Agent may be terminated by 100% of the Banks (excluding any Bank then acting as
such Agent) at any time upon thirty (30) days’ prior notice to the Company, the Agents and the
other Banks. The Required Banks, with the consent of the Company (such consent not to be
unreasonably withheld), may appoint a successor Agent to succeed any Agent that resigns or is
terminated pursuant to this Section 10.5. Subsequent to the effective date of such
resignation or termination, the resigning or terminated (as applicable) Agent shall have no further
obligations in that capacity under this Agreement.

(b) If no successor Collateral Agent shall have been appointed by the Company and the Required
Banks and shall have accepted such appointment prior to the effective date of the resignation or
termination of the then acting Collateral Agent, the resigning or terminated Collateral Agent may
appoint a successor Collateral Agent, which shall be a bank or trust company organized under the
laws of the United States of America or any State thereof, having a combined capital and surplus of
at least $500,000,000.

(c) Unless and until a successor administrative agent is appointed by the Company and the
applicable Principal Banks acting together, (i) the services performed by such Administrative Agent
hereunder shall be performed by the individual Principal Banks and the Company, each of its own
behalf, and (ii) any payments or communications made by the Company to such Administrative Agent
hereunder shall be made directly to the applicable individual Principal Banks.

Section 10.6 Non-Reliance Representation. Each of the Banks acknowledges and
represents that it has, independently of and without reliance upon any Agent, and based solely upon
its own expertise (and the expertise of its agents and independent advisors, if any) and upon
financial statements and other information deemed appropriate by it, made its own credit analysis
of the Company and made its own decision to enter into this Agreement. Each of the Banks further
acknowledges and represents that it will, independently of and without reliance upon any Agent, and
based solely upon its own expertise (and the expertise of its agents and independent advisors, if
any) and upon such documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis of the Company and its own decisions with respect to this Agreement.

Section 10.7 Exculpation. No Agent nor any of its shareholders, directors, officers,
employees or agents shall be liable to the Banks, or any of them individually, for any obligation,
undertaking, act or judgment of the Company or any other Person, or for any error of judgment or
any action taken or omitted to be taken by such Agent (except and to the extent that the same
arises from gross negligence or willful misconduct on the part of such Agent), or be bound to
ascertain or inquire as to the performance or observance of any term of any of the Loan Documents.
Without limiting the generality of the foregoing, each Agent: (a) may consult with legal counsel
selected by it and shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel; (b) makes no warranty or representation and shall
not be responsible for any warranty or representation made in or in connection with any of the Loan
Documents by any Person other than such Agent, or for the financial condition of the Company or any
other Person, or for the observance or performance of any obligations of the Company or any other
Person other than such Agent, or for the truth or accuracy of any document provided to such Agent
that such Agent has initially received from, or that such Agent has prepared based upon information
received from, the Company or any other Person, except for Collateral Agent’s responsibility under
Section 10.8; (c) makes no warranty or representation and shall not be responsible for the
due execution, validity, enforceability, sufficiency or collectibility of any of the Loan
Documents; (d) shall incur no liability under or in respect of any such agreement or document by
acting upon any notice (by telephone or otherwise), or writing (including telex and telegraphic
communication) believed by it in good faith to be genuine and to be signed or sent by the proper
party or Person; and (e) makes no warranty or guarantee as to: (i) future payments by the Company
or any other obligor or guarantor of the Loans, (ii) the Company’s future compliance with or
performance of any of the terms and conditions contained in the Loan Documents, or (iii) the
collectibility of the Loans.

Section 10.8 Collateral Valuation. Collateral Agent shall monitor the market value of
the Collateral. On each Borrowing Date, promptly after receiving notice from the Company of a
proposed borrowing, on each subsequent day on which there is an outstanding Advance, and on the
last day of each calendar month (or, if such day is not a Business Day, the next succeeding
Business Day), commencing with the first such date to occur after the date hereof, Collateral Agent
shall determine the aggregate market value of all Collateral on and as of such date in accordance
with its usual and customary practices and shall advise and notify (which may be by telephone) the
Company, Administrative Agent and each Bank thereof (each a “Collateral Notice”). Collateral Agent
agrees to deliver promptly to the Company, Administrative Agent and each Bank a written
confirmation of any telephonic Collateral Notice which is given on a Borrowing Date.

ARTICLE XI

GENERAL PROVISIONS

Section 11.1 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns, except that the Company may not assign
or otherwise transfer any of its rights under this Agreement.

(b) Any Bank may, in accordance with applicable law, at any time sell to one or more banks,
financial institutions or other entities (“Participants”) participating interests in any Loan owing
to such Bank, any Note held by such Bank, any Commitment of such Bank or any other interest of such
Bank hereunder. In the event of any such sale by a Bank of participating interests to a
Participant, such Bank’s obligations under this Agreement to the other parties to this Agreement
shall remain unchanged, such Bank shall remain solely responsible for the performance thereof and
the Company and each Agent shall continue to deal solely and directly with such Bank in connection
with such Bank’s rights and obligations under this Agreement and the other Loan Documents. In no
event shall a Bank that sells a participating interest be obligated to the Participant to take or
refrain from taking any action hereunder or under any of the other Loan Documents except that such
Bank may agree that it will not, without the consent of such Participant, agree to (A) reduce the
principal of, or interest payable on (or reduce the rate of interest applicable to), the Loans of
such Bank or any fees or other amounts payable to such Bank hereunder which, in each case, are
related to the participation sold to such Participant or, (B) postpone the date fixed for any
payment of the principal of, or interest on, the Loans of such Bank or other amounts payable to
such Bank hereunder which, in each case, are related to the participation sold to such Participant.

(c) Any Bank may (or in accordance with Section 11.4(h) shall), in accordance with
applicable law, and with the consent of the Company (such consent not to be unreasonably withheld),
and with the consent of Administrative Agent upon the occurrence and during the continuance of a
Default pursuant to Sections 8.2, 8.6 or 8.7 (such consent not to be
unreasonably withheld), at any time sell to any financial institution (all such purchasers,
collectively, “Purchasers”) all or any part of its rights and obligations under this Agreement and
the Note held by it pursuant to an assignment agreement (an “Assignment Agreement”), executed by
such Purchaser and such Bank and delivered to the Company and each Agent; provided that the
consent of the Company to any such assignment shall not be required if (A) a Default has occurred
and is continuing, (B) the assignment is by a Bank to an affiliate of such Bank or another existing
Bank or (C) the assignment (including any pledge) is by any Bank of its Notes and its rights
hereunder with respect thereto to any Federal Reserve Bank. Upon such execution and delivery of an
Assignment Agreement, from and after the effective date as specified therein, (x) the Purchaser
thereunder shall be a party hereto and shall be bound by the provisions hereto and, to the extent
provided in such Assignment Agreement, shall have the rights and obligations of a Bank hereunder,
with its Commitment as set forth in such Assignment Agreement, and (y) the transferor Bank
thereunder shall, to the extent provided in such Assignment Agreement, be released from its
obligations under this Agreement (and, in the case of an Assignment Agreement covering all or the
remaining portion of a transferor Bank’s rights and obligations under this Agreement, such
transferor Bank shall cease to be a party hereto). Upon delivery of the Assignment Agreement to
the Company and each Agent, the Company, each Agent and the Banks may treat the Purchaser as the
owner of the Loans and Commitment recorded therein for all purposes of this Agreement.

(d) On the effective date specified in any Assignment Agreement, or as soon as possible
thereafter, the Company shall execute and deliver to the applicable Purchaser, a new Note to the
order of such Purchaser reflecting the Commitment and outstanding Loans obtained by it pursuant to
such Assignment Agreement and, if the transferor Bank has retained a Commitment and Loans
hereunder, a new Note in exchange for the Note held by the transferor Bank (which existing Note
shall be surrendered to the Company) to the order of the transferor Bank reflecting the Commitment
and outstanding Loans retained by it hereunder. Such new Notes shall be dated the effective date
of the Assignment Agreement as specified therein and shall otherwise be in the form of the Note
replaced thereby. The Note surrendered by the transferor Bank shall be returned by the transferor
Bank to the Company marked “canceled”.

(e) The Company authorizes each Bank to disclose to any Participant or Purchaser and any
prospective Participant or Purchaser any and all financial and other information in such Bank’s
possession concerning the Company which has been delivered to such Bank by or on behalf of the
Company pursuant to this Agreement; provided that such Participant or Purchaser or
prospective Participant or Purchaser agrees to be bound by the confidentiality provisions contained
in Section 11.12.

(f) If, pursuant to this Section 11.1, any interest in this Agreement or any Note is
transferred to any Purchaser which is organized under the laws of any jurisdiction other than the
United States or any state thereof, such Purchaser, concurrently with the effectiveness of such
transfer and becoming a party to this Agreement pursuant to the applicable Assignment Agreement
shall, (i) represent to the transferor Bank (for the benefit of the transferor Bank, each Agent and
the Company) that under applicable law and treaties then in effect no United States federal taxes
will be required to be withheld by any Agent, the Company or the transferor Bank with respect to
any payments to be made to such Purchaser hereunder, (ii) furnish to the Company the documentation
described in Section 11.4(f), (wherein such Purchaser claims entitlement to complete
exemption from U.S. federal withholding tax on all payments hereunder) and (iii) agree to otherwise
comply with the terms of Section 11.4(f).

(g) Notwithstanding anything to the contrary contained in this Section 11.1, no Bank
may assign or sell participations, or otherwise syndicate all or any portion of such bank’s
interests under this Agreement or any other Loan Document to any Person who is (i) listed on the
Specially Designated Nationals and Blocked Persons List (the “SDN List”) maintained by the U.S.
Department of Treasury Office of Foreign Assets Control (“OFAC”) and/or on any other similar list
maintained by the OFAC pursuant to any authorizing statute, executive order or regulation or (ii)
either (x) included within the term “designated national” as defined in the Cuban Assets Control
Regulations, 31 C.F.R. Part 515, or (y) designated under Sections 1(a), 1(b), 1(c) or 1(d) of
Executive Order No. 13224, 66 Fed. Reg. 49079 (published September 25, 2001) or similarly
designated under any related enabling legislation or any other similar executive orders.

(h) The transferor Bank shall pay to Administrative Agent for its own account a fee of $3,500.

Section 11.2 Survival of Representations. All representations and warranties of the
Company contained in this Agreement shall survive delivery of the Notes and the making of the Loans
herein contemplated.

Section 11.3 Governmental Regulation. Anything contained in this Agreement to the
contrary notwithstanding, no Bank shall be obligated to extend credit to the Company in violation
of any limitation or prohibition provided by any applicable statute or regulation.

Section 11.4 Taxes.

(a) All payments to any Bank with respect to the Loans shall be made free and clear of, and
without deduction for any Indemnified Taxes or Other Taxes; provided that if the Company
shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the
sum payable shall be increased by the amount (the “Additional Amount”) necessary so that after
making all required deductions (including deductions applicable to additional sums described in
this paragraph) such Bank receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Company shall make such deductions and (iii) the Company shall pay
the full amount deducted to the relevant governmental authority in accordance with applicable law.
In addition, to the extent not paid in accordance with the preceding sentence, the Company shall
pay any Other Taxes to the relevant governmental authority in accordance with applicable law.

(b) Subject to subsections (g) and (h) below, the Company shall indemnify each
Bank for Indemnified Taxes and Other Taxes paid by such Bank, provided, however,
that the Company shall not be obligated to make payment to any Bank in respect of penalties,
interest and other similar liabilities attributable to such Indemnified Taxes or Other Taxes if
such penalties, interest or other similar liabilities are attributable to the gross negligence or
willful misconduct of such Bank.

(c) If a Bank shall become aware that it is entitled to claim a refund from a governmental
authority in respect of Indemnified Taxes or Other Taxes paid by the Company pursuant to this
Section 11.4, including Indemnified Taxes or Other Taxes as to which it has been
indemnified by the Company, or with respect to which the Company has paid Additional Amounts
pursuant hereto, it shall promptly notify the Company of the availability of such refund claim and,
if such Bank determines in good faith that making a claim for refund will not have a material
adverse effect on its taxes or business operations, shall, within 30 days after receipt of a
request by the Company, make a claim to such governmental authority for such refund at the
Company’s expense. If a Bank receives a refund in respect of any Indemnified Taxes or Other Taxes
paid by the Company pursuant hereto, it shall within 30 days from the date of such receipt pay over
such refund to the Company (but only to the extent of Indemnified Taxes or Other Taxes paid
pursuant to hereto, including indemnity payments made or Additional Amounts paid, by the Company
under this Section 11.4 with respect to the Indemnified Taxes or Other Taxes giving rise to
such refund), net of all out of pocket expenses of such Bank and without interest (other than
interest paid by the relevant governmental authority with respect to such refund).

(d) If any Bank is or becomes eligible under any applicable law, regulation, treaty or other
rule to a reduced rate of taxation, or a complete exemption from withholding, with respect to
Indemnified Taxes or Other Taxes on payments made to it by the Company, such Bank shall, upon the
request, and at the cost and expense, of the Company, complete and deliver from time to time any
certificate, form or other document requested by the Company, the completion and delivery of which
are a precondition to obtaining the benefit of such reduced rate or exemption, provided
that the taking of such action by such Bank, would not, in the reasonable judgment of such Bank be
disadvantageous or prejudicial to such Bank or inconsistent with its internal policies or legal or
regulatory restrictions. For any period with respect to which a Bank has failed to provide any
such certificate, form or other document requested by the Company, such Bank shall not be entitled
to any payment under this Section 11.4 in respect of any Indemnified Taxes or Other Taxes
that would not have been imposed but for such failure.

(e) Each Bank organized under the laws of a jurisdiction in the United States, any State
thereof or the District of Columbia (other than Banks that are corporations or otherwise exempt
from United States backup withholding Tax) shall (i) deliver to the Company, upon execution hereof
(or, with respect to Persons becoming Banks hereunder by assignment, upon execution of the relevant
assignment agreement), two original copies of United States Internal Revenue Form W-9 or any
successor form, properly completed and duly executed by such Bank, certifying that such Bank is
exempt from United States backup withholding Tax on payments of interest made under the Loan
Documents and (ii) thereafter, at each time it is so reasonably requested in writing by the
Company, deliver within a reasonable time two original copies of an updated Form W-9 or any
successor form thereto.

(f) Each Bank that is organized under the laws of a jurisdiction other than the United States,
any State thereof or the District of Columbia (each such Bank, a “Foreign Bank”) that is entitled
to an exemption from or reduction of withholding Tax under the laws of the jurisdiction in which
the Company is located, or any treaty to which such jurisdiction is a party, with respect to
payments under the Loan Documents shall deliver to the Company, upon execution hereof (or, with
respect to Persons becoming Banks hereunder by assignment, upon execution of the relevant
assignment agreement), such properly completed and duly executed documentation prescribed by
applicable law or reasonably requested by the Company as will permit such payments to be made
without withholding or at a reduced rate, unless in the good faith opinion of the Foreign Bank such
documentation would expose the Foreign Bank to any material adverse consequences or risk. Such
documentation shall be delivered by each Foreign Bank on or before the date it becomes a Bank and
on or before the date, if any, such Foreign Bank changes its applicable lending office by
designating a different lending office with respect to its Loans (a “New Lending Office”). In
addition, each Foreign Bank shall deliver such forms promptly upon the obsolescence or invalidity
of any form previously delivered by such Foreign Bank. Each Bank (and, in the case of a Foreign
Bank, its lending office), represents that on the date hereof, payments made hereunder by the
Company to it would not be subject to United States Federal withholding tax.

(g) Notwithstanding the provisions of subsection (a) and (b) above, the
Company shall not be required to indemnify any Foreign Bank, or to pay any Additional Amounts to
any Foreign Bank, in respect of United States Federal withholding tax pursuant to subsection
(a) or (b) above, (A) to the extent that the obligation to withhold amounts with
respect to United States Federal withholding tax existed on the date such Foreign Bank became a
Bank; (B) with respect to payments to a New Lending Office with respect to a Loan, but only to the
extent that such withholding tax exceeds any withholding tax that would have been imposed on such
Bank had it not designated such New Lending Office; (C) with respect to a change by such Foreign
Bank of the jurisdiction in which it is organized, incorporated, controlled or managed, or in which
it is doing business, from the date such Foreign Bank changed such jurisdiction, but only to the
extent that such withholding tax exceeds any withholding tax that would have been imposed on such
Bank had it not changed the jurisdiction in which it is organized, incorporated, controlled or
managed, or in which it is doing business; or (D) to the extent that the obligation to pay such
indemnity payment or Additional Amounts would not have arisen but for a failure by such Foreign
Bank to comply with the provisions of Section 11.4(f).

(h) If any Bank requests compensation under this Section 11.4, or if the Company is
required to pay any additional amount to any governmental authority for the account of any Bank
pursuant to this Section 11.4, then such Bank shall use reasonable efforts to designate a
different lending office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates with the object of avoiding
or eliminating the amounts payable pursuant to this Section 11.4, provided that
such designation or assignment shall be on such terms that such Bank and its lending office, in
such Bank’s sole judgment, suffer no economic, legal, regulatory or other disadvantage and would
not otherwise be disadvantageous to such Bank. The Company hereby agrees to pay all reasonable
costs and expenses incurred by any Bank in connection with any such designation or assignment.

If Bank requests compensation under this Section 11.4, or if the Company is required to pay
any additional amount to any governmental authority for the account of any Bank pursuant to this
Section 11.4, then the Company may, at its sole expense and effort, upon notice to such
Bank, require such Bank to assign and delegate, without recourse, in accordance with and subject to
the restrictions contained in Section 11.1, all of such Bank’s interests, rights and
obligations under this Agreement to one or more assignees that shall assume such obligations (which
assignee or assignees may be one or more other Banks); provided that (i) such Bank shall
have received payment of an amount equal to the outstanding principal of its Loans, accrued and
unpaid interest thereon, accrued and unpaid fees and all other amounts payable to it hereunder from
the assignee (to the extent of such outstanding principal and accrued interest and fees) or the
Company (in the case of all other amounts) and (ii) such assignment will result in a reduction in
such compensation or payments. A Bank shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the circumstances
entitling the Company to require such assignment and delegation cease to apply.

A certificate of the relevant Bank setting forth the basis for any amounts (and the calculation
thereof and methodology in calculating, each in reasonable detail) claimed under this Section
11.4 shall be delivered to the Company and shall be conclusive absent manifest error. Failure
or delay on the part of a Bank to demand compensation of any amount under this Section shall not
constitute a waiver of such Bank’s right to demand such compensation; provided that the
Company shall not be required to compensate any such Bank for any amounts claimed under this
Section that are incurred more than 90 days prior to the date that such Bank notifies the Company
of the circumstances giving rise to such amounts and such Bank’s intention to claim compensation
therefor; provided, further, that if the circumstances giving rise to such amounts have
retroactive effect, then the 90-day period referred to above shall be extended to include the
period of retroactive effect thereof.

(i) Any payment required to be made by the Company to any Bank under this Section 11.4
shall be deemed an Obligation and be secured by the Collateral.

Section 11.5 Choice of Law; Jurisdiction. The Loan Documents (other than those
containing a contrary express choice of law provision) shall be construed in accordance with the
laws of the State of Illinois (excluding choice-of-law principles of the law of such State that
would require the application of the laws of a jurisdiction other than such State), but giving
effect to federal laws applicable to national banks. The Company and the Banks hereby irrevocably
submit to the non-exclusive jurisdiction of any United States federal or Illinois state court
sitting in Chicago, Illinois in any action or proceedings arising out of or relating to any Loan
Documents and the Company and the Banks hereby irrevocably agree that all claims in respect of such
action or proceeding may be heard and determined in any such court.

Section 11.6 Headings. Section headings in the Loan Documents are for convenience of
reference only, and shall not govern the interpretation of any of the provisions of the Loan
Documents.

Section 11.7 Entire Agreement. The Loan Documents embody the entire agreement and
understanding among the Company and the Banks and supersede all prior agreements and understandings
among the Company and the Banks relating to the subject matter thereof.

Section 11.8 Several Obligations. The respective obligations of the Banks hereunder
are several and not joint and no Bank shall be the partner or agent of any other. The failure of
any Bank to perform any of its obligations hereunder shall not relieve any other Bank from any of
its obligations hereunder.

Section 11.9 Expenses; Indemnification.

(a) The Company shall reimburse each Agent and each Bank for any reasonable costs, internal
charges and out-of-pocket expenses (including reasonable attorneys’ fees and time charges of
attorneys, which attorneys may be employees of such Agent or such Bank, as applicable) paid or
incurred by such Agent or such Bank, as applicable, in connection with the collection, liquidation
and enforcement of the Loan Documents and/or the Collateral. The Company further agrees to
indemnify each Agent, each Bank and their respective directors, officers and employees (each an
“Indemnified Party”) against all losses, claims, damages, penalties, judgments, liabilities and
expenses (including, without limitation, all expenses of litigation or preparation therefor) which
any of them may pay or incur arising out of or relating to this Agreement, the other Loan
Documents, the transactions contemplated hereby or the direct or indirect application or proposed
application of the proceeds of any Loan hereunder (all of the foregoing being collectively referred
to as “Indemnified Amounts”), excluding, however, in all of the foregoing instances, Indemnified
Amounts arising from the gross negligence or willful misconduct on the part of the Indemnified
Party seeking indemnification and Indemnified Amounts consisting of taxes imposed on or measured by
the overall net income of the Indemnified Party seeking indemnification.

(b) If, after the date hereof, any law or any governmental rule, regulation, policy, guideline
or directive (whether or not having the force of law) is adopted, or there is any change in the
interpretation thereof, or the compliance of any Bank with such, which, in any case, affects the
amount of capital required or expected to be maintained by such Bank or any corporation controlling
such Bank, and such Bank reasonably determines the amount of capital required is increased by or
based upon the existence of this Agreement or its Commitment hereunder and such increased capital
results in increased costs to such Bank, then, such Bank shall notify the Company of such fact and
shall provide a reasonably detailed description of such increased costs in the notice (“Increased
Cost Notice”), together with documentation from the relevant regulatory body setting forth such
increased capital requirement, and within 15 days of the Company’s receipt of such Increased Cost
Notice, the Company shall, in its sole discretion, determine whether to terminate such Bank’s
Commitment and obligation to make Loans hereunder, or to attempt to negotiate with such Bank a
revised commitment fee (which revision shall not constitute an amendment to Section 2.8
hereof for the purposes of Section 9.2) and any other reimbursements provided for hereunder
which reflect such Bank’s increased costs. In the event that the Company determines to terminate
such Bank’s Commitment and obligation to make Loans hereunder, the Company shall send written
notice to such Bank within 15 days of the Company’s receipt of the Increased Cost Notice specifying
a date at least 30 days thereafter on which such Bank’s Commitment and obligation to make Loans
hereunder shall be terminated. In the event that the Company determines to attempt to negotiate
with such Bank a revised commitment fee and other reimbursements, and the Company and such Bank are
unable to agree, within 30 days of the date of the Increased Cost Notice, upon such revised fees
and other reimbursements, such Bank may send written notice to the Company, or the Company may send
written notice to such Bank specifying a date at least 30 days thereafter on which the Bank’s
Commitment and obligation to make Loans hereunder shall be terminated. Any payment required to be
made by the Company under this Section 11.9(b) shall be deemed an Obligation and be secured
by the Collateral.

(c) At least 45 days prior to the proposed consummation date of any merger or consolidation of
the Company with or into any other Person in which the Company shall not be the surviving entity
(such transaction, a “Restructuring”), the Company will give written notice thereof to
Administrative Agent (a “Restructuring Notice”), which notice shall set forth the material terms
and conditions of such Restructuring, including the identity of the surviving entity of such
Restructuring (the “Survivor”). Administrative Agent shall promptly provide a copy of the
Restructuring Notice to each Bank. Upon receipt of a Restructuring Notice, a Bank may elect, in
its sole discretion, to terminate its Commitment hereunder by notifying the Company and
Administrative Agent thereof, which may be by telephone (a “Termination Notice”) within 15 days of
such Bank’s receipt of the Restructuring Notice, which termination shall become effective no sooner
than 30 days after the Company’s receipt of the Termination Notice. Any Bank that fails to deliver
a Termination Notice within 15 days after its receipt of a Restructuring Notice shall be deemed to
have elected to terminate its Commitment.

(d) The effective date of any termination of a Bank’s Commitment hereunder pursuant to
subsection (b) or (c) above is referred to herein as such Bank’s “Accelerated
Termination Date”. Any such termination shall not accelerate the maturity of any Loans outstanding
to such Bank; commitment fees to such Bank shall cease to accrue as of its Accelerated Termination
Date; and the Company shall be responsible for any and all Obligations and accrued and unpaid costs
(including increased costs), fees and expenses incurred with respect to such Bank prior to its
Accelerated Termination Date. The obligations of the Company under this Section 11.9 shall
survive the termination of this Agreement.

Section 11.10 Accounting. Except as provided to the contrary herein, all accounting
terms used herein shall be interpreted and all accounting determinations hereunder shall be made in
accordance with Agreement Accounting Principles.

Section 11.11 Severability of Provisions. Any provision in any Loan Document that is
held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that
jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions
in that jurisdiction or the operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

Section 11.12 Confidentiality. Each of the Banks and each Agent agrees to maintain
the confidentiality of the Company Information, except that Company Information may be disclosed
(a) to its affiliates, directors, officers, employees and agents, including accountants, legal
counsel and other advisors who have a need to know such information (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential nature of such Company
Information and agree to keep such Company Information confidential on terms substantially similar
to this Section 11.12), (b) to any governmental agency or representative thereof,
provided that prior to such disclosure, the disclosing party shall, to the extent
practicable, promptly inform the Company of such potential disclosure, (c) to the extent required
by applicable laws or regulations or by any subpoena or similar legal process or to the extent
reasonably required in connection with any litigation relating to this Agreement or the Collateral
to which such Bank or such Agent, as applicable, is a party, (d) subject to an agreement containing
provisions substantially the same as those described in this Section 11.12, to any
Purchaser or Participant or any prospective Purchaser or Participant, (e) with the consent of the
Company or (f) to the extent such Company Information becomes publicly available other than as a
result of a breach of its confidentiality obligations as described in this Section 11.12.

As used in this Section, “Company Information” means all information received from the Company
or any of its Subsidiaries or Affiliates relating to Holdings or any of its subsidiaries (including
the Company) or any of their respective affiliates, or their businesses, other than any such
information that is available to any Agent or any Bank, as applicable, on a non-confidential basis
prior to disclosure by the Company.

Section 11.13 WAIVER OF TRIAL BY JURY. TO THE EXTENT PERMITTED BY APPLICABLE LAW,
EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT OF TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY MATTER
ARISING HEREUNDER OR THEREUNDER.

Section 11.14 USA Patriot Act Notification. The following notification is provided to
the Company pursuant to Section 326 of the USA Patriot Act:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government of
the United States of America fight the funding of terrorism and money laundering activities,
Federal law requires all financial institutions to obtain, verify, and record information that
identifies each Person that opens an account, including any deposit account, treasury management
account, loan, other extension of credit, or other financial services product. Accordingly, when
the Company opens an account, Administrative Agent, Collateral Agent and the Banks will ask for the
Company’s name, tax identification number, business address, and other information that will allow
Administrative Agent, Collateral Agent and the Banks to identify such Company. Administrative
Agent, Collateral Agent and the Banks may also ask to see the Company’s legal organizational
documents or other identifying documents.

ARTICLE XII

SETOFF; RATABLE PAYMENTS

Section 12.1 Setoff; Ratable Payments.

(a) In addition to, and without limitation of, any rights of the Banks under applicable law,
if the Company becomes insolvent, however evidenced, or any Default occurs and is continuing, any
indebtedness from any Bank to the Company (including all account balances, whether provisional or
final and whether or not collected or available but excluding any accounts designated as or
representing “customer segregated funds” accounts and any accounts pledged to such Bank to secure
an overdraft facility to ensure the settlement of foreign currency futures and options contracts
traded on the Company) may be offset and applied toward the payment of the Obligations owing to
such Bank, whether or not the Obligations, or any part thereof, shall then be due.

(b) If any Bank, whether by setoff or otherwise, has payment made to it upon any Loan in a
greater proportion than that received by any other Bank upon any Loan constituting a portion of the
same Advance, such Bank shall distribute to Administrative Agent an amount equal to each of the
other Banks’ pro rata share of such payment. Such payment shall be distributed ratably between the
Banks in proportion to each Bank’s respective share of the total Obligations outstanding under this
Agreement. Any payment distributed pursuant to this subsection (b) to Administrative Agent
shall be distributed by Administrative Agent to the applicable Banks in accordance with the
provisions of this Agreement.

(c) If any Bank, whether in connection with setoff or amounts which might be subject to setoff
or otherwise, receives collateral or other protection for any category of its Obligations or such
amounts which may be subject to setoff, in any case, in excess of its pro rata share thereof, such
Bank agrees, promptly upon demand, to take such action necessary such that all Banks share in the
benefits of such collateral ratably in proportion to their Obligations of the same category. In
case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments
shall be made.

(d) The Company agrees that any holder of a participation in a Loan may, to the fullest extent
permitted by law, exercise all its rights of payment with respect to such participation as if such
holder were the direct creditor of the Company in the amount of the participation.

ARTICLE XIII

NOTICES

Section 13.1 Giving Notice. Except as otherwise herein provided, any notice required

SWIFT message, in each case, addressed to the Company, the Agents and the Banks at the addresses or
transmission numbers indicated below their signatures to the Agreement or otherwise notified to the

SUBORDINATION

The Company hereby subordinates its Lien on the Collateral to the Lien therein granted to
