        Section 2.7    Post-Closing Adjustment.    

        (a)   Within 90 days following the Closing Date, Seller shall prepare and deliver to IDB Buyer a consolidated balance sheet of the Seller Retained Subsidiaries as of the Closing (giving effect to the Estimated Available Cash Allocation) (the "Seller Closing Balance Sheet"), which shall be prepared in conformity with GAAP applied on a basis consistent with the preparation of, and using the same accounting methods, policies, practices, procedures and estimation methods as those used in the preparation of the balance sheet for the fiscal year ended December 31, 2013, included in the GFI Financial Statements, and which shall include a calculation of Available Cash at the Seller Retained Subsidiaries and Working Capital derived from the items and amounts on such balance sheet. Within 90 days following the Closing Date, IDB Buyer shall prepare and deliver to Seller a consolidated balance sheet of IDB Buyer and the IDB Subsidiaries as of the Closing (giving effect to the Estimated Available Cash Allocation) (the "IDB Buyer Closing Balance Sheet" and together with the Seller Closing Balance Sheet, the "Closing Balance Sheets"), which shall be prepared in conformity with GAAP applied on a basis consistent with the preparation of, and using the same accounting methods, policies, practices, procedures and estimation methods as those used in the preparation of the balance sheet for the fiscal year ended December 31, 2013, included in the GFI Financial Statements, and which shall include a calculation of Available Cash at the IDB Subsidiaries and Tangible Common Equity, in each case derived from the items and amounts on such balance sheet. The Parties agree that the purpose of preparing the Closing Balance Sheets and determining the Available Cash, Working Capital and Tangible Common Equity and the related adjustment contemplated by this Section 2.7 is to measure the amount of Available Cash, Working Capital and Tangible Common Equity and such processes are not intended to permit the introduction of different judgments, accounting methods, policies, principles, practices, procedures, classifications or estimation methodologies for the purpose of preparing the Closing Balance Sheets or determining Available Cash, Working Capital and Tangible Common Equity.

        (b)   Following delivery of the Seller Closing Balance Sheet and the IDB Buyer Closing Balance Sheet and prior to the deadline for delivering a Dispute Notice, each of Seller and IDB Buyer will provide the other Party and its Representatives with reasonable access to the books and records, personnel and related work papers of Seller or IDB Buyer, as applicable, in connection with such other Party's review of the Seller Closing Balance Sheet or the IDB Buyer Closing Balance Sheet, as applicable. Each of Seller and IDB Buyer shall have 45 days after the later delivery of the Seller Closing Balance Sheet or IDB Buyer Closing Balance Sheet in which to provide to the other Party a notice setting forth, in detail, any good faith dispute as to any item or amount reflected in the Seller Closing Balance Sheet (including the calculations of Available Cash and Working Capital set forth therein) or the IDB Buyer Closing Balance Sheet (including the calculations of Available Cash and Tangible Common Equity set forth therein), as applicable, and the basis for such dispute together with such Party's calculation of such item or amount in dispute (the "Dispute Notice", and each item or amount on the Dispute Notice, a "Disputed Item"). Other than the Disputed Items, each Party shall be deemed to have accepted all items and amounts contained in the Seller Closing Balance Sheet or the IDB Buyer Closing Balance Sheet, as applicable, delivered by the other Party pursuant to Section 2.7(a).

12

        (c)   For 30 days after the later delivery of the Dispute Notice by Seller or IDB Buyer, Seller and IDB Buyer shall endeavor in good faith to resolve by mutual agreement all Disputed Items. If, for any reason, Seller and IDB Buyer are unable to resolve any Disputed Item within such 30 day period, Seller and IDB Buyer shall engage Deloitte & Touche LLP (the "Independent Accountant Arbitrator") to make a determination as to the Disputed Items; provided that if the Independent Accountant Arbitrator is unable or unwilling to serve in this capacity, then Seller and IDB Buyer shall within 14 days after the end of such 30 day period agree on an alternate independent accounting firm or in default thereof such selection shall be made pursuant to the rules of the American Arbitration Association, which accounting firm shall be the "Independent Accountant Arbitrator" hereunder. The fees, costs and expenses of the Independent Accountant Arbitrator will be borne by Seller and IDB Buyer in relative proportion to the amount by which the aggregate calculation of the Disputed Items by each of them differs from the calculation to be made by the Independent Accountant Arbitrator.

        (d)   If there is a referral to the Independent Accountant Arbitrator, each of Seller and IDB Buyer agrees, if requested by the Independent Accountant Arbitrator, to execute a reasonable engagement letter and shall submit to the Independent Accountant Arbitrator not later than ten Business Days after its appointment, a written statement summarizing its position on the Disputed Items, together with such supporting documentation as it deems necessary. The Independent Accountant Arbitrator shall act as an arbitrator to determine, based solely on the materials submitted and presentations by Seller and IDB Buyer, and not by independent review, only the Disputed Items that have not been settled by negotiation, and its determination with respect to each Disputed Item shall be an amount within the range established with respect to such Disputed Item by Seller's or IDB Buyer's calculation in the Seller Closing Balance Sheet or IDB Buyer Closing Balance Sheet, as applicable, on the one hand, and the applicable Dispute Notice, on the other hand. Seller and IDB Buyer shall instruct the Independent Accountant Arbitrator to render its decision within 30 days of its appointment or as soon thereafter as is reasonably practicable. The decision/award of the Independent Accountant Arbitrator as to the Disputed Items shall be final and binding on, and shall not be subject to appeal by, Seller and IDB Buyer or any other Person, and may be entered and enforced as provided in Section 9.9.

        (e)   No later than 30 days following the later of the final determination of the Seller Closing Balance Sheet (and the calculations of Available Cash and Working Capital set forth therein) or the IDB Buyer Closing Balance Sheet (and the calculations of Available Cash and Tangible Common Equity set forth therein) (such items being "final" after giving effect to the items and amounts accepted or deemed to have been accepted by either Seller or IDB Buyer, Disputed Items settled by negotiation and Disputed Items finally determined by the Independent Accountant Arbitrator; such final calculations being the "Final Available Cash Allocation"), the following adjustments shall be effected:

          (i)  if any of the amounts that were transferred or retained by the IDB Subsidiaries at Closing as provided in the Estimated Available Cash Allocation were in excess of the corresponding amounts that should have been transferred or retained by the IDB Subsidiaries as provided in the Final Available Cash Allocation, then IDB Buyer shall (or shall cause the applicable IDB Subsidiaries to) pay the amount of such excess(es) to Seller.

         (ii)  if any of the amounts that were transferred or retained by the Seller Retained Subsidiaries as provided in the Estimated Available Cash Allocation were in excess of the corresponding amounts that should have been transferred or retained by the Seller Retained Subsidiaries as provided in the Final Available Cash Allocation, then Seller shall (or shall cause the applicable Seller Retained Subsidiaries to) pay the amount of such excess(es) to IDB Buyer. Notwithstanding the foregoing and for the avoidance of doubt, in no event shall Seller be required to pay an amount in excess of the Excess Cash Amount.

13

        Section 2.8    Direct Holders of Purchased Interests.    

        (a)   Seller shall cause each Seller Retained Subsidiary that is a direct equityholder of Purchased Interests to take any and all action to sell, transfer and assign the Purchased Interests to IDB Buyer at the Closing. References in Section 2.1 (Purchase and Sale of the Purchased Interests) to the obligations of Seller to sell, transfer and assign to IDB Buyer all of Seller's right, title and interest to the Purchased Interests, shall be read as obligations of Seller to procure that the applicable Seller Retained Subsidiary makes such sale, transfer and assignment to IDB Buyer.

        (b)   Any payment of the Purchase Price, or any payment under Section 5.7(h) (Tax Indemnity), Section 8.2 (Indemnification) or any other indemnification provision, shall, to the extent that it relates to entities comprising the Purchased Interests or any of their respective Subsidiaries, be received or made by Seller acting on behalf of such entities or other applicable Seller Indemnified Party.

For purposes of this Agreement, a "Burdensome Condition" shall mean making proposals, executing or carrying out agreements (including consent decrees) or submitting to Laws (i) providing for the transfer, license, sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Seller, IDB Buyer or any of their respective Affiliates or the holding separate (through the establishment of a trust or otherwise) of the Securities of any Affiliate of Seller or IDB Buyer, (ii) obligating either IDB Buyer or Seller or any of their respective Affiliates or principals, directors, officers, employees or agents to provide a material guarantee of material obligations of any third party or extend any material loan or financing to any person or provide for the material indemnification any person, or (iii) imposing or seeking to impose any limitation on the ability of Seller, IDB Buyer or any of their respective Affiliates to conduct their respective businesses (including, with respect to, market practices and structure) or own such assets or to acquire, hold or exercise full rights of ownership of the business of Seller, IDB Buyer or their respective Affiliates, in each case other than (1) with respect to Antitrust Laws, any such proposals, executing or carrying out agreements (including consent decrees) or submitting to Laws that would not impair in any material respect the expected benefits of Seller and its Affiliates or IDB Buyer and its Affiliates, as applicable, from or relating to the Transactions, (2) with respect to Regulatory Approvals, (A) in the case of Seller or its Affiliates or principals, directors, officers, employees or agents, any de minimis administrative or ministerial obligations of Seller or any of its Affiliates, or (B) in the case of IDB Buyer or its Affiliates or principals, directors, officers, employees or agents, any such proposals, executing or carrying out agreements (including consent decrees) or submitting to Laws that would not constitute a Material Adverse Effect, or (3) with respect to the Commercial Agreements (other than the IDB Market Data Service Agreement) and the provisions of Section 5.22 (Commercial Agreements), any such proposals, executing or carrying out agreements (including consent decrees) or submitting to Laws that would not impair in any material respect the expected benefits of Seller and its Affiliates or IDB Buyer and its Affiliates, as applicable, from or relating to the Commercial Agreements (other than the IDB Market Data Service Agreement) or the provisions of Section 5.22 (Commercial Agreements).

IDB Buyer shall, and IDB Buyer shall cause JPI, New JPI and its and their respective Representatives to, immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives conducted prior to the date of this Agreement with respect to any Takeover Proposal and shall request the prompt return or destruction of any confidential information previously furnished to such Persons in connection therewith in accordance with the terms of any applicable confidentiality agreement. Notwithstanding the foregoing, nothing herein shall prevent any Representative of JPI or New JPI from acting in his or her capacity as an officer or director of GFI, or taking any action in such capacity, but only in either such case as and to the extent permitted by Section 6.5(b) of the GFI Merger Agreement.

        (b)   For purposes of this Agreement, "Takeover Proposal" means any proposal or offer for a direct or indirect (i) merger, binding share exchange, recapitalization, reorganization, scheme of arrangement under the United Kingdom Companies Act 2006, liquidation, dissolution, business combination or consolidation, or any similar transaction, involving GFI or one or more of its Subsidiaries (including the IDB Subsidiaries), (ii) the acquisition or purchase, including by lease, exchange, mortgage, pledge, transfer or other acquisition or assumption, of 20% or more of the fair value of the assets or 20% or more of any class of equity or voting securities of (A) GFI and its Subsidiaries or (B) the IDB Subsidiaries, in each case taken as a whole and in one transaction or a series of related transactions, (iii) purchase, tender offer, exchange offer or other acquisition (including by way of merger, consolidation, share exchange or otherwise) of Beneficial Ownership of Securities representing 20% or more of the voting power of GFI' or any of the IDB Subsidiary's Securities, or (iv) any transaction, or combination of transactions, similar to the foregoing; provided, however, that the term "Takeover Proposal" shall not include the Transactions.

        Section 5.4    Fees and Expenses.    Except as set forth in Section 8.3(b) of the GFI Merger Agreement, whether or not the Transactions are consummated, all Expenses incurred in connection with this Agreement and the Transactions shall be paid by the Party incurring such Expenses, except with respect to all fees associated with the HSR Act and the Foreign Competition Laws, which shall be borne equally by Seller and IDB Buyer. As used in this Agreement, "Expenses" includes all out-of-pocket expenses (including, all fees and expenses of counsel, accountants, investment bankers, experts and consultants to a Party and its Affiliates) incurred by a Party or on its behalf in connection with or related to the authorization, preparation, negotiation, execution and performance of this Agreement and the Transactions, including all other matters related to the Transactions.

        Section 5.5    Public Announcements.    Seller and IDB Buyer shall develop a joint communications plan and each Party shall (a) ensure that all of its press releases and other public statements or communications with respect to the Transactions shall be consistent with such joint communications plan and (b) unless otherwise required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, consult with each other before issuing any press release or, to the extent practicable, otherwise making any public statement or communication with respect to this Agreement or the Transactions. In addition to the foregoing, none of Seller, IDB Buyer,

26

JPI, New JPI or any of their respective Affiliates shall issue any press release or otherwise make any public statement or disclosure concerning any other Party or any other Party's business, financial condition or results of operations without the consent of such other Party, which consent shall not be unreasonably withheld, conditioned or delayed.

        Section 5.6    Notice of Certain Events.    Each of Seller and IDB Buyer shall promptly notify the other after receiving or becoming aware of (a) any written notice from any Person alleging that the consent of that Person is or may be required in connection with the Transactions, (b) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would be reasonably likely to (i) prevent or materially delay the consummation of the Transactions or (ii) result in the failure of any condition to the Closing set forth in Article VI to be satisfied, or (c) any Proceeding commenced or, to the Knowledge of IDB Buyer, threatened against, relating to or otherwise involving Seller or IDB Buyer or any of the IDB Subsidiaries, as the case may be, that relates to the consummation of the Transactions; provided, however, that the delivery of any notice pursuant to this Section 5.6 shall not limit or otherwise affect the remedies available hereunder to the Party receiving such notice.

        Section 5.7    Tax Matters.    

        (a)    Tax Filings.     

          (i)  IDB Buyer shall prepare and timely file the Tax Returns of any of the IDB Subsidiaries if such Tax Return is not part of a GFI Consolidated Return.

         (ii)  IDB Buyer shall prepare (or cause to be prepared) the GFI Consolidated Returns. In preparing the GFI Consolidated Returns, IDB Buyer shall (i) consult with Seller on a regular basis concerning the status of the GFI Consolidated Returns with respect to the reporting of any material item of income, deduction, gain, loss, credit or other Tax item related to the GFI Consolidated Returns; (ii) make available to Seller all information, working papers, and data used in the preparation of the GFI Consolidated Returns; and (iii) follow the instruction and direction provided by Seller regarding the preparation and contents of the GFI Consolidated Returns and any related working papers. Without limiting the forgoing, no later than 45 days prior to the due date (taking into account any valid extensions thereof) (the "Due Date") for the filing of any GFI Consolidated Return, IDB Buyer shall submit a draft of the GFI Consolidated Return to Seller for Seller's review. IDB Buyer shall timely revise such draft GFI Consolidated Return based on the comments and instructions of Seller and shall make any further revisions required by Seller in order to deliver a version of the GFI Consolidated Return that is acceptable to Seller (a "Final GFI Consolidated Return") no later than 15 days prior to the applicable Due Date. Upon receipt of a Final GFI Consolidated Return, Seller shall timely file the Final GFI Consolidated Return with the appropriate Governmental Entity. Notwithstanding the above, for any Tax item related to the GFI Consolidated Return that would result in an indemnity payment from IDB Buyer, IDB Buyer will consider in good faith any comments provided by Seller regarding the preparation and contents of the GFI Consolidated Returns and any related working papers. Any items reflected on a Tax Return described in this Section 5.7(a)(ii) with respect to which IDB Buyer and Seller are unable to agree after negotiating in good faith for five (5) days and which would result in an indemnity payment from IDB Buyer shall be referred to the Independent Accountant Arbitrator for resolution as promptly as practicable. The determination of the Independent Accountant Arbitrator shall be final, conclusive, and binding for all purposes hereunder. IDB Buyer shall timely revise such draft GFI Consolidated Return to reflect this determination.

        (iii)  Seller shall prepare and timely file (or cause to be prepared and timely filed) all Tax Returns required to be filed by the Seller Retained Subsidiaries (other than the GFI Consolidated Returns) that are either Pre-Closing Tax Returns required to be filed after the Closing Date or Straddle Period Tax Returns. IDB Buyer shall prepare and timely file (or

27

cause to be prepared and timely filed) all Pre-Closing Tax Returns required to be filed by the Seller Retained Subsidiaries prior to the Closing Date; provided that, no later than 20 days prior to the Due Date for the filing of any such Tax Return, IDB Buyer shall submit, or cause to be submitted, a draft of such Tax Return to Seller for its review. IDB Buyer shall consider in good faith all reasonable comments provided by Seller with respect to any such draft Tax Return within ten days of IDB Buyer providing such draft Tax Return to Seller.

        (iv)  All Tax Returns required to be prepared by IDB Buyer under this Section 5.7 shall be prepared in a manner consistent with prior practice, and IDB Buyer shall be responsible for the costs and expenses incurred in connection with the preparation of such Tax Returns.

        (b)    Payment of Taxes.    With respect to any Taxes related to any Tax Return required to be filed by IDB Buyer pursuant to this Section 5.7, IDB Buyer shall timely pay or cause the appropriate Person to timely pay any such Taxes to the appropriate Governmental Entity and shall timely provide evidence to Seller that such payment has been made. With respect to any Taxes related to any Tax Return required to be filed by Seller pursuant to this Section 5.7, Seller shall timely pay or cause the appropriate Person to timely pay any such Taxes to the appropriate Governmental Entity and shall timely provide evidence to IDB Buyer that such payment has been made.

        (c)    Tax Allocation.    The portion of any Tax related to a Straddle Period that is allocable to the portion of a Straddle Period ending on and including the Closing Date shall be (i) in the case of property and similar ad valorem Taxes and any other Taxes not described in clause (ii) below, equal to the amount of such Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that fall prior to the day after the Closing Date and the denominator of which is the number of days in the entire Straddle Period and (ii) in the case of Taxes based on income, receipts, remuneration, sales, proceeds, profits or similar items and other Taxes that are readily apportionable based on an actual or deemed closing of the books, computed as if such taxable period ended as of the close of business on the Closing Date. The portion of any Tax related to a Straddle Period that is allocable to the portion of the Straddle Period beginning the day after the Closing Date is the portion of such Tax not allocable to the portion of the Straddle Period ending on and including the Closing Date under this Section 5.7(c). Notwithstanding anything to the contrary in this Agreement, any transaction that occurs on the Closing Date but prior to the actual time of the Closing and that is not in the ordinary course of business shall be deemed to occur in a Pre-Closing Tax Period or the portion of a Straddle Period ending on and including the Closing Date.

        (d)    Tax Contests.    IDB Buyer, at its own expense, shall have the right to control and direct any Tax audit, initiate any claim for refund, and contest, resolve and defend against any other assessment, notice of deficiency, or other adjustment or proposed adjustment (each such audit or proceeding, a "Tax Contest") relating to any Pre-Closing Tax Return or Straddle Period Tax Return of the IDB Subsidiaries; provided that (i) IDB Buyer provides written notice to Seller of its intent to control such Tax Contest within 15 days of receiving notice of such Tax Contest and (ii) such Tax Contest does not involve issues that could reasonably be expected to affect the Tax liability or attributes of Seller or its Affiliates (including the Seller Retained Subsidiaries). With respect to any Tax Contest controlled by IDB Buyer pursuant to this Section 5.7(d) that could reasonably be expected to affect the Tax liability or attributes of Seller or its Affiliates in a Post-Closing Tax Period, IDB Buyer shall not, without the prior written consent of Seller (which consent shall not be unreasonably withheld, conditioned or delayed), compromise or settle such Tax Contest. Seller may, at its own expense, participate in any such Tax Contest and employ counsel separate from the counsel employed by IDB Buyer. With respect to any Tax Contest relating to a Pre-Closing Tax Return or Straddle Period Tax Return of GFI, the Seller Retained Subsidiaries and, to the extent that it involves issues that could affect the Tax attributes or liability of Seller or its Affiliates

28

(including the Seller Retained Subsidiaries), the IDB Subsidiaries, Seller shall control and direct such Tax Contest; provided that (a) IDB Buyer may, at its own expense, participate in any such Tax Contest and employ counsel separate from the counsel employed by Seller and (b) without the prior written consent of IDB Buyer (which consent shall not be unreasonably withheld, conditioned or delayed) Seller shall not compromise or settle such Tax Contest if (i) such compromise or settlement would result in indemnification of the Seller Indemnified Parties pursuant to Section 5.7(h) and (ii) IDB Buyer has acknowledged in writing that any Taxes payable to Seller or its Affiliates in connection with such Tax Contest will result in indemnification of the Seller Indemnified Parties to the extent such Taxes otherwise would give rise to an indemnification payment pursuant to Section 5.7(h).

        (e)    Cooperation.    With respect to all Tax Returns required to be filed pursuant to this Section 5.7, Seller and IDB Buyer shall retain all Tax Returns, schedules and work papers and all material records (whether paper, electronic or other format) or other documents or electronic data in its possession (or in the possession of their respective Affiliates) relating to Tax matters relevant to the Pre-Closing Tax Period and Straddle Periods until the later of (i) the expiration of the statute of limitations of the taxable periods to which such Tax Returns and other documents relate, taking into account all extensions thereof, or (ii) six years following the Due Date for such Tax Returns. IDB Buyer or Seller shall be permitted to remove and retain any such documents prior to disposition of any such documents by the other Party by written request delivered no later than 30 days prior to such time. A Party seeking to retain such documents after such time shall bear all expenses associated with the removal and further retention of such documents. After the Closing, with respect to any Tax Return required to be filed pursuant to this Section 5.7, IDB Buyer and Seller shall (i) reasonably assist (and cause their respective Affiliates to reasonably assist) the other Party in preparing and filing any Tax Returns that such other Party is responsible for preparing, (ii) reasonably cooperate in preparing for any audits of, or disputes or other proceedings with any Governmental Entity or with respect to any matters related to such Tax Returns, and (iii) make available to the other Party and to any Governmental Entity, as reasonably requested, all information, records, and documents relating to such Tax Returns.

        (f)    Tax Sharing.    Any and all Tax sharing, allocation, indemnification or similar agreements or arrangements to which any of GFI, the IDB Subsidiaries or the Seller Retained Subsidiaries is a party or otherwise subject shall be terminated as of the Closing Date and no payments relating thereto shall be made subsequent to the Closing Date.

        (g)    Tax Reporting.    Each of Seller and IDB Buyer will file all Tax Returns in a manner consistent with treating (i) the JPI Mergers and GFI Mergers as reorganizations under Section 368(a) of the Code and (ii) the Sale and Assumption as a sale of the IDB Subsidiaries by Seller or its Affiliates to IDB Buyer occurring immediately after the GFI Mergers. The Parties agree to provide each other with any information required to complete IRS Form 8594 within ten days of the request for such information. No later than 90 days after the Closing Date, Seller shall prepare and deliver to IDB Buyer (i) an allocation of the "amount realized" from the sale of the IDB Subsidiaries (the "Tax Consideration") between Seller and GFI EMEA Holdings Ltd (the "U.S.-Foreign Tax Allocation") and (ii) the proposed allocation of the Tax Consideration in a manner consistent with the U.S.-Foreign Tax Allocation for purposes of Section 1060 of the Code (together with the U.S.-Foreign Tax Allocation, the "Proposed Tax Allocation"). In the event that IDB Buyer objects in writing to the Proposed Tax Allocation within 30 days, IDB Buyer and Seller shall negotiate in good faith to resolve the dispute. If IDB Buyer and Seller fail to agree on such allocation within 30 days following IDB Buyer's written objection, such allocation shall be determined, within a reasonable time, by the Independent Accountant Arbitrator selected in accordance with Section 2.7(c). The allocation of the Tax Consideration, as agreed upon by Seller and IDB Buyer (as a result of either the absence of manifest error or good faith negotiations

29

between IDB Buyer and Seller) or determined by the Independent Accountant Arbitrator pursuant to this Section 5.7(g) (the "Final Tax Allocation") shall be final and binding upon the Parties and each of IDB Buyer and Seller shall bear all fees and costs incurred by it in connection with the determination of the allocation of the Tax Consideration, except that the Parties shall each pay 50% of the fees and expenses of the Independent Accountant Arbitrator. Seller shall prepare (in a manner consistent with the Final Tax Allocation) and deliver IRS Form 8594 to IDB Buyer, and Seller and IDB Buyer shall each timely file such form with the IRS. Seller and IDB Buyer shall prepare and file all Tax Returns consistent with such Final Tax Allocation, and in any Proceeding related to the determination of any Tax, none of IDB Buyer, Seller, or their Affiliates (unless otherwise required by a "determination" within the meaning of Section 1313(a) of the Code) shall contend or represent, whether orally or in writing, that the Final Tax Allocation is not a correct allocation.

        (h)    Tax Indemnity.     

          (i)  IDB Buyer shall (without duplication) be liable and shall indemnify and hold the Seller Indemnified Parties harmless against, all Tax liabilities suffered by Seller Indemnified Parties arising out of, incident to, or as a result of: (A) any IDB Buyer Responsible Taxes; (B) the breach by IDB Buyer of any covenant or agreement of IDB Buyer contained in this Section 5.7; (C) any amount required to be paid by Seller or any of its Affiliates under a Tax sharing, allocation or indemnification agreement (other than this Agreement, any agreement between or among GFI and its Subsidiaries (other than the IDB Subsidiaries) or any written agreement entered into in the ordinary course of business the primary purpose of which does not relate to Taxes or any commercial lending agreement) or on a transferee or successor liability theory, in respect of any Taxes of any Person, if such agreement or event or transaction giving rise to transferee or successor liability was entered into, or relates to any transaction engaged in by GFI, the IDB Subsidiaries or the Seller Retained Subsidiaries, prior to the Closing Date; or (D) any breach by GFI or any GFI Subsidiary of Section 5.1(o)(vi) of the GFI Merger Agreement.

         (ii)  Seller shall (without duplication) be liable and shall indemnify and hold the IDB Buyer Indemnified Parties harmless against, all Tax liabilities suffered by the IDB Buyer Indemnified Parties arising out of, incident to, or as a result of (A) Taxes of the Seller Retained Subsidiaries for any Post-Closing Tax Period and for the portion of any Straddle Period that begins after the Closing Date; and (B) the breach by Seller of any covenant or agreement of Seller contained in this Section 5.7.

        (iii)  In the case of any claim for indemnification under this Section 5.7(h), the indemnified party shall endeavor to give prompt written notification to the indemnifying party of the commencement of any action, suit or proceeding relating to a third-party claim for which an indemnified party intends to seek indemnification; provided, however, that no delay on the part of the indemnified party in giving any such notice shall relieve the indemnifying party of any indemnification obligation hereunder (except to the extent that, solely as a result of such delay, the indemnifying party is prevented from contesting the liability for which indemnification is sought).

        (iv)  Any indemnification payment made pursuant to Section 8.2 (Indemnification) or this Section 5.7(h) shall be treated as a purchase price adjustment for all Tax purposes unless otherwise required by applicable Law.

        Section 5.8    Employee Plans.    

        (a)   Effective as of the Closing, (i) IDB Buyer shall (or shall cause the IDB Subsidiaries to) retain or assume, as applicable, all liabilities and obligations under or otherwise in respect of each GFI

Benefit Plan (but determined as if Section 3.16(a) of the GFI Merger Agreement was not limited to material plans, programs, agreements and arrangements) exclusive of those such GFI Benefit Plans maintained immediately before the Closing exclusively by the Seller Retained Subsidiaries solely for the benefit of Continuing Employees (such GFI Benefit Plans whose obligations are assumed or retained by IDB Buyer or the IDB Subsidiaries, the "IDB Buyer Assumed Benefit Arrangements"), and (ii) IDB Buyer shall cause each Continuing Employee to cease participation in any IDB Buyer Assumed Benefit Arrangement.

        (b)   Prior to the Closing, IDB Buyer shall, and shall cause the IDB Subsidiaries to, fully comply with all notice, consultation, effects bargaining or other bargaining obligations to any labor union, labor organization, works council or group of employees of the IDB Subsidiaries in connection with the Transactions.

        (d)    Modification.     In the event that the covenants in this Section 5.10 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great of time or over too great a geographical area or by reason of its being too extensive in any other respect, they shall be interpreted to extend only over the maximum period of time for which they may be enforceable and/or over the maximum geographical area as to which they may be enforceable and/or to the maximum extent in all other respects as to which they may be enforceable, all as determined by such court in such action.

All payments and reimbursements that from time to time after the Closing may be received by IDB Buyer or the IDB Subsidiaries arising out of the Seller Retained Businesses shall be held for the benefit of Seller or the applicable Seller Retained Subsidiary and, promptly upon receipt thereof, IDB Buyer shall pay to Seller or the applicable Seller Retained Subsidiary the amount of such payment or reimbursement without any delay, deduction or setoff.

        Section 5.14    Assignment of Pre-Closing Proceedings.    IDB Buyer shall cooperate with the parties to each Pre-Closing Proceeding (except to the extent involving the IDB Subsidiaries, in which case such Pre-Closing Proceedings do not need to be assigned) with a view to entering into arrangements effective as of the Closing whereby IDB Buyer would be substituted (for the avoidance of doubt, which substitution shall include an unconditional written release) for the applicable parties to such Pre-Closing Proceedings (including, for the avoidance of doubt, the filing of necessary pleadings and motions promptly following the Closing). To the extent the assignment of any Pre-Closing Proceeding (i) requires a consent which has not been obtained, (ii) is ineffective or (iii) is otherwise not completed (each such Pre-Closing Proceeding until it has been assigned, a "Delayed Pre-Closing Proceeding"), this Agreement and the Ancillary Agreements shall not constitute an agreement to assign or otherwise transfer at the Closing any such Delayed Pre-Closing Proceeding; provided, however, the Parties shall treat each Delayed Pre-Closing Proceeding as an Assumed Liability hereunder as of the Closing. IDB Buyer shall have the sole right and responsibility to control, defend, settle, compromise or prosecute in any manner such Delayed Pre-Closing Proceedings after the Closing at its sole cost and expense;

33

provided, however, that, without the prior written consent of Seller, IDB Buyer shall not (i) settle or compromise a Delayed Pre-Closing Proceeding or consent to the entry of any Order with respect thereto which does not include an unconditional, duly authorized, fully executed and acknowledged (by a duly registered notary public) written release by the claimant or plaintiff of the Seller and its Affiliates, including the Seller Retained Subsidiaries, and its and their respective Representatives from all liability in respect of such Delayed Pre-Closing Proceeding; (ii) settle or compromise any Delayed Pre-Closing Proceeding if the settlement imposes equitable remedies or other obligations on the Seller or its Affiliates, including the Seller Retained Subsidiaries, or its or their respective Representatives; or (iii) settle or compromise any Delayed Pre-Closing Proceeding if the result is to admit civil or criminal liability or culpability on the part of the Seller or its Affiliates, including the Seller Retained Subsidiaries, or its or their respective Representatives that gives rise to criminal liability with respect to any such Person. Without limiting the generality of Section 5.11, Seller shall provide, and cause its Affiliates to provide, at IDB Buyer's sole expense, reasonable cooperation to IDB Buyer in connection with (i) effecting the assignment of each Delayed Pre-Closing Proceeding as expeditiously as practicable following the Closing (including, for the avoidance of doubt, the filing of necessary pleadings and motions) and (ii) the defense, prosecution and/or settlement of any such Delayed Pre-Closing Proceedings. Following the Closing and until the time all Delayed Pre-Closing Proceedings have been assigned to IDB Buyer, Seller shall, and shall cause its Affiliates to, promptly pay, assign and remit to IDB Buyer any monies actually received by Seller or its Affiliates from any Person solely to the extent they are in respect of a Delayed Pre-Closing Proceeding, including any monies actually received from pre-Closing insurers of GFI or its Affiliates.

        Section 5.15    Public Deal Proceedings.    If the Closing occurs, IDB Buyer and Seller agree that all Losses incurred by any Seller Indemnified Party or any IDB Buyer Indemnified Party in respect of Public Deal Proceedings (if any) shall be allocated and funded as follows: (i) the first source of recovery shall be the Excess Cash Amount (if any) and (ii) any remaining Losses of any Seller Indemnified Party will be split equally by Seller and IDB Buyer; provided, however, that if payment by IDB Buyer in cash of its payment obligation under clause (ii) would, after giving effect to such payment by IDB Buyer, result in IDB Buyer not being compliant with its regulatory capital requirements or in default under its credit agreement (each, a "Compliance Failure"), IDB Buyer and Seller shall negotiate in good faith the terms of a Security to be issued by IDB Buyer to Seller in lieu of such portion of such cash payment the payment of which would result in a Compliance Failure. This Section 5.15 shall not apply to Public Deal Proceedings commenced by any current or former stockholder or member of IDB Buyer, JPI or New JPI, and in such case, IDB Buyer shall indemnify the Seller Indemnified Parties for all Losses in connection therewith but subject to the proviso to clause (ii) above. For purposes of this Section 5.15, "Losses" shall be net of any amounts actually recovered under any applicable directors' and officers' liability insurance and fiduciary liability insurance policy or policies; provided, however, the amount of any such insurance recovery shall be reduced by any out-of-pocket costs and expenses incurred in obtaining such insurance recovery.

        Section 5.16    Financing.    

        (a)   IDB Buyer acknowledges and agrees that Seller and its Affiliates and its and their respective Representatives shall not have any responsibility for, or incur any liability to any Person under, any financing that IDB Buyer may raise in connection with the transactions contemplated by this Agreement and that IDB Buyer shall indemnify and hold harmless Seller and its Affiliates and its and their respective Representatives from and against any and all losses, damages, claims, costs or expenses suffered or incurred by any of them in connection with the Debt Financing (including any claims asserted by the Financing Sources) and any information utilized in connection therewith.

        (b)   IDB Buyer shall, and shall cause its Representatives and Affiliates to, take, or cause to be taken, all actions and do, or cause to be done, all things necessary, proper or advisable to arrange and consummate the Debt Financing as soon as reasonably practical after the date of this Agreement, but

34

in any event prior to the Closing and to obtain the proceeds of the Debt Financing on the terms and conditions, taken as a whole (including the flex provisions) described in the Debt Commitment Letter, including executing and delivering all such documents and instruments as may be reasonably required thereunder, including definitive agreements with respect to the financing on the terms and conditions contained in the Debt Commitment Letter (the "Debt Financing Documents") and:

          (i)  complying with and maintaining in effect the Debt Financing and the Debt Commitment Letter, negotiating and entering into definitive Debt Financing Documents with respect thereto (and maintaining in effect and complying with the terms thereof) on the terms and conditions (as such terms may be modified or adjusted in accordance with the terms of, and within the limits of, any "flex" provisions set forth in the Debt Commitment Letter (including as specified in any Fee Letter provided pursuant to Section 3.11)) no less favorable, taken as a whole, to IDB Buyer than those contained in the Debt Commitment Letter, which agreements shall be in effect as promptly as practicable after the date hereof, but in no event later than the Closing Date; provided, however, that, without limiting the foregoing, in no event shall any of the Debt Financing Documents (nor shall any amendment, supplement, waiver or other modification thereto be reasonably expected to): (A) reduce the aggregate amount of the Debt Financing provided for in the Debt Commitment Letter (including by changing the amount of fees or original issue discount contemplated by the Debt Commitment Letter other than, solely with respect to original issue discount, as expressly set forth therein unless after giving effect to the maximum amount of any such deduction, the aggregate net proceeds from the Debt Financing are and will be sufficient in amount to provide IDB Buyer with the funds necessary to consummate the transactions contemplated hereby and to satisfy its obligations under this Agreement, including to pay the Purchase Price, and the payment of all fees, costs and expenses to be paid by IDB Buyer related to the transactions contemplated by this Agreement, including such fees and expenses relating to the Debt Financing); (B) expand the conditions or other contingencies to the receipt or funding of the Debt Financing beyond those expressly set forth in the Debt Commitment Letter, amend or modify any of such conditions or other contingencies in a manner adverse to IDB Buyer or Seller (including by making any such conditions or other contingencies less likely to be satisfied) or impose any new or additional condition or other contingency to the receipt or funding of the Debt Financing; (C) contain terms (other than those terms expressly set forth in the Debt Commitment Letter that would reasonably be expected to (1) prevent, impede or delay the consummation of the transactions contemplated by this Agreement or the Debt Commitment Letter or the date on which the Debt Financing would be obtained, or (2) make the funding of Debt Financing less likely to occur; (D) adversely impact the ability of IDB Buyer to enforce its rights against the Financing Sources; or (E) impose obligations on Seller and its Affiliates;

         (ii)  satisfying, or causing its Representatives to satisfy, as promptly as practicable and on a timely basis all conditions to the Debt Financing contemplated by the Debt Commitment Letter and Debt Financing Documents relating thereto (including by paying any commitment, engagement or placement or other fees that become due and payable under or with respect to the Debt Commitment Letter or Debt Financing Documents);

        (iii)  accepting (and complying with) to the fullest extent all "market flex" provisions contemplated by the Debt Commitment Letter and the Debt Financing Documents;

        (iv)  obtaining all rating agency approvals necessary to obtain the Debt Financing;

         (v)  enforcing its rights under the Debt Commitment Letter and Debt Financing Documents in the event of a breach by the Financing Sources under the Debt Commitment Letter and Debt Financing Documents relating thereto; and

35

        (vi)  causing the Financing Sources and any other Persons providing Debt Financing to fund the Debt Financing in immediately available funds at the time the Closing is required to occur pursuant to the terms and conditions hereof.

        (c)   IDB Buyer shall not agree to or permit any amendment, supplement or other modification or replacement of, or grant any waiver of any condition, remedy or other provision under, the Debt Commitment Letter or the Debt Financing Documents without the prior written consent of Seller if such amendment, supplement, modification, replacement or waiver would or would reasonably be expected to (i) reduce the aggregate amount of the Debt Financing (including by changing the amount of fees or original issue discount contemplated by the Debt Commitment Letter other than, solely with respect to original issue discount, as expressly set forth therein unless after giving effect to the maximum amount of any such deduction, the aggregate net proceeds from the Debt Financing are and will be sufficient in amount to provide IDB Buyer with the funds necessary to consummate the transactions contemplated hereby and to satisfy its obligations under this Agreement, including to pay the Purchase Price, and to pay all fees, costs and expenses to be paid by IDB Buyer related to the transactions contemplated by this Agreement, including such fees and expenses relating to the Debt Financing), from that contemplated by the Debt Commitment Letter delivered as of the date hereof, (ii) impose new or additional conditions or otherwise expand, amend or modify any of the conditions to the receipt or funding of the Debt Financing in a manner adverse to Seller or IDB Buyer, (iii) make it less likely that the Debt Financing would be funded (including by making the conditions to obtaining the Debt Financing less likely to occur) or otherwise prevent or delay or impair the ability or likelihood of IDB Buyer to timely consummate the transactions contemplated by this Agreement, (iv) adversely impact the ability of IDB Buyer to enforce its rights against the other parties to the Debt Commitment Letter or (v) otherwise contravene the limitations set forth in Section 5.16(b)(i)(A)-(E). IDB Buyer shall not agree to the withdrawal, repudiation, termination or rescission of the Debt Commitment Letter or Debt Financing Documents or any provision thereof without the prior written consent of Seller. Upon any amendment, supplement or modification of the Debt Commitment Letter in accordance with this Section 5.16(c), IDB Buyer shall deliver a copy thereof to Seller and references herein to "Debt Commitment Letter" shall include such documents as amended, supplemented or modified in compliance with this Section 5.16(c) and references to "Debt Financing" shall include the financing contemplated by the Debt Commitment Letter as amended, supplemented or modified in compliance with this Section 5.16 and the financing contemplated by the Debt Financing Documents entered into in compliance with this Section 5.16, as applicable.

        (d)   In the event that all or any portion of the Debt Financing becomes or could become unavailable on the terms and conditions (including any "flex" provisions) or from the sources contemplated in the Debt Commitment Letter or the Debt Financing Documents for any reason or the Debt Commitment Letter or the Debt Financing Documents shall be withdrawn, repudiated, terminated or rescinded for any reason (but without limiting the obligations of IDB Buyer in the penultimate sentence of Section 5.16(c) and in Section 5.16(b)(v) ), (i) IDB Buyer shall immediately so notify Seller and (ii) IDB Buyer shall arrange and obtain, as promptly as practicable following the occurrence of such event (and in any event no later than the Closing Date), and shall negotiate and enter into definitive agreements with respect to, alternative financing from the same or alternative sources (the "Alternative Financing") in an amount sufficient to consummate the transactions contemplated by this Agreement and pay all related fees and expenses (or replace any unavailable portion of the Debt Financing), and shall obtain a new financing commitment letter (including any associated engagement letter and related fee letter) with respect to such Alternative Financing (collectively, the "New Debt Commitment Letter"), copies of which shall be promptly provided to Seller. Notwithstanding the foregoing, no New Debt Commitment Letter may expand upon the conditions precedent or contingencies to the funding or receipt of the Debt Financing on the Closing Date as set forth in the Debt Commitment Letter in effect on the date hereof or otherwise include terms (including any "flex" provisions) that would reasonably be expected to make the likelihood that such

36

Debt Financing would be funded less likely. In the event any Alternative Financing is obtained and a New Debt Commitment Letter is entered into in accordance with this Section 5.16(d) (i) any reference in this Agreement to "Debt Financing" shall mean the debt financing contemplated by the Debt Commitment Letter as modified pursuant to clause (ii) below, and (ii) any reference in this Agreement to the "Debt Commitment Letter" (or defined terms that use such phrases) and to "Debt Financing Documents" shall be deemed to include the Alternative Financing and any New Debt Commitment Letter. Without Seller's prior written consent, IDB Buyer shall not directly or indirectly take any action that could result in the Debt Financing not being available.

        (e)   Any breach of the Debt Commitment Letter or the Debt Financing Documents by IDB Buyer shall be deemed a breach by IDB Buyer of this Section 5.16. IDB Buyer shall (i) furnish Seller drafts (when available) and thereafter complete, correct and executed copies of the Debt Financing Documents promptly upon their execution, (ii) give Seller prompt written notice of any default, breach or threatened breach by any party to the Debt Commitment Letter or Debt Financing Documents of any of the Debt Commitment Letter or the Debt Financing Documents of which IDB Buyer or any of its Representatives or Affiliates becomes aware or any termination or threatened termination thereof and (iii) otherwise keep Seller reasonably informed of the status of its efforts to arrange the Debt Financing (or any Alternative Financing). Without limiting the generality of the foregoing, IDB Buyer shall give Seller prompt (and in any event within two Business Days) notice (A) of any breach or default (or any event or circumstance that, with or without notice, lapse of time or both, would reasonably be expected to give rise to any default or breach) related to the Debt Financing of which IDB Buyer becomes aware, (B) of the receipt or delivery of any notice or other communication, in each case from any Person with respect to (x) any actual or potential breach of any provisions of the Debt Commitment Letter or Debt Financing Documents by IDB Buyer, or any default, termination or repudiation by any party to the Debt Commitment Letter or Debt Financing Documents or other agreements relating to the Debt Financing or (y) any dispute or disagreement between or among parties to the Debt Commitment Letter or Debt Financing Documents with respect to the obligation to fund the Debt Financing or the amount of the Debt Financing to be funded at the Closing and (C) if at any time for any reason IDB Buyer believes that it will not be able to obtain all or any portion of the Debt Financing on the terms and conditions, in the manner or from the sources, contemplated by the Debt Commitment Letter or Debt Financing Documents or will be unable to obtain Alternative Financing. IDB Buyer shall promptly provide any information reasonably requested by Seller relating to any circumstance referred to in clause (A), (B) or (C) of the immediately preceding sentence.

        (f)    Seller and its Affiliates shall use their reasonable best efforts to, and shall use their reasonable best efforts to cause their respective Representatives to use their reasonable best efforts to, provide, at IDB Buyer's sole expense, all cooperation necessary for IDB Buyer to obtain the Debt Financing as may be reasonably requested by IDB Buyer; provided that nothing herein shall require such cooperation to the extent it would reasonably be expected to (i) interfere with the ongoing businesses or operations of Seller or any of its Affiliates, (ii) require Seller or any of its Affiliates to agree to pay any fees, reimburse any expenses or otherwise incur any liability or give any indemnities, require Seller or any of its Affiliates to take any action that would reasonably be expected to conflict with, or result in any violation or breach of, or default (with or without notice of lapse of time, or both) under, their respective Constituent Documents, any applicable Laws or any contract, or (iii) require Seller or any of its Affiliates to provide access to or disclose information that Seller reasonably determines would jeopardize their respective attorney-client privilege. In furtherance of and without limitation to the immediately preceding sentence, nothing herein shall require Seller or any of its Affiliates to be an issuer or other obligor with respect to the Debt Financing or require their respective boards of directors or equivalent governing bodies to approve or authorize the execution of agreements relating to the Debt Financing. IDB Buyer shall promptly, upon request by Seller, reimburse Seller for all reasonable out-of-pocket costs and expenses (including reasonably attorneys' fees) incurred by Seller or any of its Affiliates or any of its or their respective Representatives in connection with the Debt

37

Financing or in connection with their cooperation contemplated by this Section 5.16(f) and shall indemnify and hold harmless the Seller Indemnified Parties from and against any and all Losses actually suffered or incurred by any of them in connection with the arrangement of the Debt Financing and any information used in connection therewith (other than arising from fraud or intentional misrepresentation in information provided in writing by Seller specifically for use in connection therewith).

        (g)   Notwithstanding anything to the contrary contained herein, (i) no Seller Related Party (other than IDB Buyer) shall have any rights or claims against any Financing Source in connection with this Agreement, the Debt Financing or the transactions contemplated hereby or thereby, whether at law or equity, in contract, in tort or otherwise, (ii) the Seller Related Party (other than the IDB Buyer) agrees not to commence (and if commenced agrees to dismiss or otherwise terminate) any proceeding against any Financing Source in connection with this Agreement or the transactions contemplated hereby (including any proceeding relating to the Debt Financing) and (iii) no Financing Source shall have any rights or claims against any Seller Related Party (other than IDB Buyer) in connection with this Agreement, the Debt Financing or the transactions contemplated hereby or thereby, whether at law or equity, in contract, in tort or otherwise.

        (h)   Notwithstanding anything contained in this Agreement to the contrary, (i) IDB Buyer acknowledges and agrees that the obtaining of the Debt Financing is not a condition to the Closing, and reaffirms its obligations under this Section 5.16 and (ii) IDB Buyer's breach of any of its representations or warranties in Section 3.11, IDB Buyer's breach of any of its obligations in this Section 5.16, the failure, for any reason, of IDB Buyer to have sufficient cash available to pay the Purchase Price in accordance with Article II and/or the failure to so pay the Purchase Price on the Closing Date, in each case, shall constitute a breach of this Agreement by IDB Buyer.

        Section 5.17    Affiliate Transactions.    Effective as of the Closing, IDB Buyer agrees that all intercompany receivables or payables and loans existing and outstanding as of the Closing Date between the Seller Retained Subsidiaries, on the one hand, and any IDB Buyer Related Party, on the other hand, shall be settled (whether in the ordinary course of business or by way of capital contribution, gift, distribution, dividend or otherwise) or otherwise cancelled. Seller and IDB Buyer acknowledge and agree (on behalf of themselves and on behalf of each Seller Retained Subsidiary and each IDB Buyer Related Party, as applicable) that all contracts, agreements, commitments and arrangements between any Seller Retained Subsidiary, on the one hand, and any IDB Buyer Related Party, on the other hand, other than those set forth in Section 5.17 of the IDB Buyer Disclosure Letter, shall be deemed terminated as of the Closing Date and of no further force or effect, and Seller and IDB Buyer shall cause each Seller Retained Subsidiary, in the case of Seller, and each IDB Buyer Related Party, in the case of IDB Buyer, not to take any action or assert any claim that is inconsistent with such deemed termination.

        Section 5.18    Intellectual Property License.    To the extent that, after the Closing, IDB Buyer or any of its Affiliates (including the IDB Subsidiaries) owns any Intellectual Property that is used in the businesses of the Seller Retained Subsidiaries, as currently conducted or currently proposed to be conducted by GFI and the GFI Subsidiaries as of the Closing, IDB Buyer, for itself and on behalf of its Affiliates (including the IDB Subsidiaries), hereby grants to the Seller Retained Subsidiaries and their Affiliates a perpetual, irrevocable, fully paid up, royalty-free, sublicenseable, transferable, non-exclusive license to make, have made, use, sublicense, import, display, perform, distribute, transmit, copy, create derivative works of and otherwise exploit such Intellectual Property (excluding any Intellectual Property subject to the IDB Market Data Service Agreement), including to import and sell products that embody such Intellectual Property, solely in relation to such businesses.

38

        Section 5.19    Discontinuance of Use of Names.    

        (a)   Subject to Section 5.19(b), within 90 days after the Closing, Seller and its Affiliates shall (i) to the extent permitted by Law, eliminate the use of the name "GFI" in any of its forms or spellings, in all electronic communications, on all stationery, business cards, checks, form purchase orders and acknowledgments, form customer agreements and other form contracts and business documents (except to the extent necessary to (1) collect any accounts receivable and (2) runoff the current stock of such items) and will cancel or terminate all doing business certificates or filings with respect to such name and (ii) make any and all filings with Governmental Entities reasonably required to change its trade names, business names and doing-business-as designations to remove such name.

        (b)   Notwithstanding the foregoing, Seller and its Affiliates may use the "GFI" name (i) as required by Law, (ii) to the extent required in regulatory filings, (iii) in a non-promotional manner for historical reference to company names, products or other materials bearing such name, and (iv) in a non-promotional manner in reference to products and services bearing such name that were sold prior to the Closing.

        Section 5.20    Conduct.    On the Closing Date, for so long as Seller is the direct or indirect parent entity of the IDB Subsidiaries, Seller will maintain and preserve the IDB Business, the IDB Subsidiaries and the IDB Subsidiaries' assets and will not, and will cause its Affiliates (including the IDB Subsidiaries) to not, take any action, including the granting of Liens over the Securities of the IDB Subsidiaries or any asset of the IDB Subsidiaries, with respect to the IDB Subsidiaries or the IDB Business other than as necessary and contemplated by the Transactions; provided that if for any reason the Seller or any of its Affiliates grants any Liens on the Securities of the IDB Subsidiaries or any asset of the IDB Subsidiaries, and with respect to such grant a Lien attaches to the Securities of the IDB Subsidiaries or any asset of the IDB Subsidiaries in favor of Seller's or any of its Affiliates' creditors, Seller shall cause such Lien to be released at or prior to the Closing.

        Section 5.21    Transaction Documents.    Seller will not, and will cause its Affiliates not to, amend the GFI Merger Agreement or waive any conditions thereto in any manner adverse to the rights and obligations of the IDB Buyer or the IDB Buyer's stockholders without the prior written consent of IDB Buyer (such consent not to be unreasonably withheld, conditioned or delayed). This Section 5.21 shall not survive the Closing.

        Section 5.22    Commercial Agreements.    

        (a)   From and after the Closing, (i) IDB Buyer and its Affiliates (including the IDB Subsidiaries) shall offer the clearing services of CME Clearing to the customers, traders, brokers and other users of the IDB Business across all asset classes at prices and on terms at least as favorable as the prices and terms that IDB Buyer and its Affiliates (including the IDB Subsidiaries) offer all other clearing services to such customers, traders, brokers and other users of the IDB Business and (ii) IDB Buyer and Seller shall consult with each other regularly, and at least once per quarter if requested by IDB Buyer or Seller, with a view to improving the experience of customers, traders, brokers and other users of the IDB Business with CME Clearing.

        Section 8.2    Indemnification.    

        (a)    By IDB Buyer.    Except with respect to Taxes and Tax Returns, which shall be governed exclusively by Section 5.7, from and after the Closing, and subject to the limitations set forth in this Article VIII, IDB Buyer shall indemnify, defend and hold harmless Seller, its Affiliates, the Seller Retained Subsidiaries, their respective successors and assigns and the Representatives of each of the foregoing (collectively, the "Seller Indemnified Parties") from and against all losses, damages, liabilities, claims, costs and expenses, interest, penalties, judgments and settlements (collectively, "Losses") that arise out of, result from or are incident to, directly or indirectly:

          (i)  the breach or inaccuracy of any representation or warranty made by IDB Buyer under Article III (including the IDB Buyer Disclosure Letter), except IDB Buyer Identified Representations (it being understood that for purposes of this Section 8.2, such representations and warranties shall be deemed to have been made as of the date of this Agreement and as of the Closing Date, except to the extent such representations and warranties are made on or as of a specified date, in which case the same shall continue to be true and correct as of the specified date);

         (ii)  the breach or inaccuracy of any IDB Buyer Identified Representation (including the IDB Buyer Disclosure Letter) (it being understood that for purposes of this Section 8.2, such representations and warranties shall be deemed to have been made as of the date of this

43

Agreement and as of the Closing Date, except to the extent such representations and warranties are made on or as of a specified date, in which case the same shall continue to be true and correct as of the specified date);

        (iii)  the breach of or failure to perform any covenant or agreement contained in this Agreement by IDB Buyer;

        (iv)  the Purchased Interests and Assumed Liabilities;

         (v)  the IDB Subsidiaries and the IDB Business whether before or after the Closing;

        (vi)  the Pre-Closing Reorganization;

      (viii)  any failure by GFI or a GFI Subsidiary prior to Closing to undertake any right to work checks and/or secure appropriate visas or other necessary immigration authorizations or licenses required by the applicable immigration authorities.

        (b)    By Seller.    Except with respect to Taxes and Tax Returns, which shall be governed exclusively by Section 5.7, from and after the Closing, and subject to the limitations set forth in this Article VIII, Seller shall indemnify, defend and hold harmless IDB Buyer, its Affiliates, their respective successors and assigns and the Representatives of each of the foregoing (collectively, the "IDB Buyer Indemnified Parties") from and against any and all Losses that arise out of, result from or are incident to, directly or indirectly:

          (i)  the breach or inaccuracy of any representation or warranty made by Seller under Article IV (it being understood that for purposes of this Section 8.2, such representations and warranties shall be deemed to have been made as of the date of this Agreement and as of the Closing Date, except to the extent such representations and warranties are made on or as of a specified date, in which case the same shall continue to be true and correct as of the specified date);

         (ii)  the breach of or failure to perform any covenant or agreement contained in this Agreement by Seller;

        (iii)  the Seller Retained Subsidiaries, the Trayport Business and the FENICS Business whether before or after the Closing except to the extent relating to the Assumed Liabilities or any breach of any representation, warranty or covenant of IDB Buyer contained in this Agreement; and

        (iv)  the Senior Notes due 2018.

        (c)   For purposes of determining whether there has been, or the amount of any Losses related to, a breach or inaccuracy of any representation or warranty made by IDB Buyer under Article III (other than Section 3.7 and Section 3.14 in accordance with the next sentence) or by Seller under Article IV, the representations and warranties set forth in this Agreement shall be considered without regard to any "material," "Material Adverse Effect" or similar qualifications set forth

44

therein. Notwithstanding the foregoing, the "material," "Material Adverse Effect" and similar qualifications in the representations and warranties set forth in Exhibit F shall be applicable for purposes of determining whether there has been, or the amount of any Losses related to, a breach of the representation and warranty made by IDB Buyer in Section 3.14.

        (d)    Procedures.    

          (i)  Any Person seeking any indemnification under this Section 8.2 (an "Indemnified Party"), acting through IDB Buyer or Seller, as applicable, shall give the party from whom indemnification is being sought (an "Indemnifying Party") prompt notice (a "Claim Notice") of any matter which such Indemnified Party has determined has given or could give rise to a right of indemnification under this Section 8.2; provided, however, if an Indemnified Party shall receive written notice of any Third Party Claim, the Indemnified Party shall give the Indemnifying Party a Claim Notice within 20 days after receipt by the Indemnified Party of such notice. The Claim Notice shall (i) indicate whether the Indemnity Claim results from or arises out of a third party claim (a "Third Party Claim") or a direct claim, (ii) describe with reasonable specificity the nature of the Indemnity Claim and (iii) state the amount of Losses sought pursuant to such Indemnity Claim to the extent then known. The failure to deliver or timely deliver the Claim Notice shall not affect the rights of the Indemnified Party to indemnification under this Section 8.2, except and only to the extent that the Indemnifying Party shall have been actually and materially prejudiced by reason of such failure.

         (ii)  Third Party Claims.

        (1)   The Indemnifying Party shall have the right to conduct at its expense the defense of a Third Party Claim, upon delivery of notice to the Indemnified Party (the "Defense Notice") within 20 days after the Indemnifying Party's receipt of the Claim Notice; provided that the Defense Notice shall specify the counsel the Indemnifying Party will appoint to defend such Third Party Claim and acknowledge, without qualification, the right of the Indemnified Party to be indemnified for Losses incurred in connection with such Third Party Claim. The Indemnified Party shall be entitled to be indemnified for the reasonable fees and expenses of counsel for any period during which the Indemnifying Party has not assumed the defense of any such Third Party Claim in accordance herewith. If the Indemnifying Party timely delivers a Defense Notice and thereby elects to conduct the defense of the Third Party Claim, the Indemnified Party will cooperate with and make available to the Indemnifying Party such assistance and materials as the Indemnifying Party may reasonably request, all at the sole expense of the Indemnifying Party, and the Indemnified Party shall have the right at its expense to participate in the defense assisted by counsel of its own choosing.

        (2)   The Indemnifying Party shall not be entitled to control the defense of any Third Party Claim if (i) such Indemnity Claim is with respect to a criminal proceeding, action, indictment, allegation or investigation, (ii) the Indemnified Party has been advised by counsel that a reasonable likelihood exists of a material conflict of interest between the Indemnifying Party and the Indemnified Party with respect to such Third Party Claim, or (iii) such Third Party Claim seeks an injunction or other equitable relief against the Indemnified Party. In the event of any of the foregoing circumstances and the Indemnified Party has nonetheless permitted the Indemnifying Party to control the defense of such Third Party Claim, the Indemnified Party shall be entitled to retain its own counsel, and the Indemnifying Party shall pay the reasonable fees and expenses of one counsel (in addition to any required local counsel).

        (3)   The Indemnifying Party shall not, without the prior written consent of the Indemnified Party (i) settle or compromise a Third Party Claim or consent to the entry of

45

any Order which does not include an unconditional written release by the claimant or plaintiff of the Indemnified Party from all liability in respect of the Third Party Claim; (ii) settle or compromise any Third Party Claim if the settlement imposes equitable remedies or other obligations on the Indemnified Party; or (iii) settle or compromise any Third Party Claim if the result is to admit civil or criminal liability or culpability on the part of the Indemnified Party that gives rise to criminal liability with respect to the Indemnified Party. No Third Party Claim which is being defended by the Indemnifying Party in accordance with the terms of this Agreement shall be settled or compromised by the Indemnified Party without the prior written consent of the Indemnifying Party (such consent not to be unreasonably withheld, conditioned or delayed).

        Section 8.3    Certain Limitations on Indemnification.    

        (a)   No amount of Losses shall be payable pursuant to Section 8.2(a)(i) to any Seller Indemnified Party unless the aggregate amount of all Losses that are indemnifiable pursuant to Section 8.2(a)(i) exceeds $2,095,000 (the "Deductible"), upon which the aggregate amount of all Losses in excess of such Deductible shall be recoverable in accordance with the terms hereof. For the avoidance of doubt, the Deductible shall be calculated in the aggregate with respect to all Indemnity Claims by Seller Indemnified Parties pursuant to Section 8.2(a)(i).

        (b)   In no event shall the aggregate amount of Losses for which Seller Indemnified Parties shall be entitled to indemnification pursuant to Section 8.2(a)(i) exceed $41,900,000 (the "Cap"). For the avoidance of doubt, the Cap shall be calculated in the aggregate with respect to all Indemnity Claims by Seller Indemnified Parties pursuant to Section 8.2(a)(i).

        (c)   The amount of any Loss subject to indemnification under Section 8.2 shall be calculated net of (i) any Tax Benefit actually realized and utilized by the Indemnified Party on account of such Loss in the taxable year in which the indemnification payment is made or a prior taxable year, and (ii) any insurance proceeds, indemnity, contribution or other similar payment actually recovered by the Indemnified Party from any third party with respect thereto; provided, however, that (A) no Indemnified Party shall be required to pursue insurance or other collateral sources to offset Losses which are indemnifiable under Section 8.2 and (B) the amount of such recovery shall be reduced by any costs and expenses incurred in obtaining such recovery and by the amount of any increase in insurance premiums resulting from making the claim giving rise to such recovery. For purposes hereof, "Tax Benefit" shall mean, with respect to any Loss subject to indemnity under Section 8.2, an amount by which the Tax liability of a party (or a group of Persons filing a Tax Return that includes such party), with respect to a taxable period, is reduced as a result of such Loss or the amount of Tax refund that is generated as a result of such Loss. In the event that an insurance or other recovery is made by any Indemnified Party with respect to any Loss for which any such Indemnified Party has been indemnified hereunder, then the Indemnified Party shall promptly pay to the Indemnifying Party the amount of such recovery, but in no event shall the amount of such payment to the Indemnifying Party exceed the amount of the indemnification payment made to the Indemnified Party.

        Section 8.4    Mitigation.    Nothing in this Article VIII regarding indemnification rights and obligations shall be deemed to override any obligations with respect to mitigation of Losses existing under applicable Law.

        Section 8.5    Pledge Agreement.    MNC Holdco LLC, a Delaware limited liability company, shall pledge such number of shares of CME Class A Common Stock having a value equal to $100,000,000 based on the Average Closing CME Stock Price (as defined in the GFI Merger Agreement) to secure IDB Buyer's indemnification obligations under this Agreement, pursuant to and in accordance with the terms as set forth therein.

46

        Section 8.6    Contribution.    If the indemnification provided for in this Article VIII for any reason is held by a court of competent jurisdiction or by an arbitrator to be unavailable to an Indemnified Party in respect of any Losses arising from or relating to an Indemnity Claim, then the Indemnifying Party, in lieu of indemnifying an Indemnified Party hereunder, shall, to the extent permitted by applicable Law, contribute to the amount paid or payable by the Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the Indemnified Party in connection with the action or inaction which resulted in such Losses, as well as any other relevant equitable considerations. The Indemnifying Party and the Indemnified Party agree that it would not be just and equitable if contribution pursuant to this Section 8.6 were determined by pro rata or per capita allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding sentence.

        Section 8.7    Sole and Exclusive Remedy.    From and after the Closing, except in the case of (a) willful misconduct with respect to the breach of a covenant or agreement contained in this Agreement or (b) fraud, the indemnification terms set forth in this Article VIII shall constitute the sole and exclusive remedy of the Parties (and the Indemnified Parties) for any and all Losses or other claims relating to or arising from any breach of the representations, warranties, covenants and agreements contained in this Agreement, and the Parties hereby agree that no Party (and no Indemnified Party) shall have any remedy or recourse with respect to any of the foregoing other than as expressly set forth in this Article VIII (and subject to the limitations and terms set forth in this Article VIII). The Parties agree that the provisions in this Agreement relating to indemnification, and the limits imposed on the remedies of the Parties with respect to this Agreement and the transactions contemplated hereby, were specifically bargained for between sophisticated parties. Nothing in this Article VIII shall limit any Person's right to seek and obtain any equitable relief to which any Person shall be entitled pursuant to Section 9.10.

        Section 9.2    Interpretation.    When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings (including headings contained in parentheticals to Section and Article references) contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation." As it relates to IDB Buyer, the words "made available" shall be deemed to mean that such information was (a) provided in writing to CME or its Representatives,

48

(b) included in GFI's electronic data room or (c) was otherwise available in GFI's public filings on the SEC's public website (www.sec.gov); provided, that the immaterial omission of a document or part of a document shall not mean that such information was not "made available." The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

        Section 9.3    Counterparts; Effectiveness.    This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same instrument. This Agreement shall become effective when each Party shall have received counterparts thereof signed and delivered by the other Parties. Signatures transmitted electronically shall be accepted as originals for all purposes of this Agreement.

        Section 9.4    Entire Agreement; Third Party Beneficiaries.    

        (a)   This Agreement (including the Exhibits and IDB Buyer Disclosure Letter), the Ancillary Agreements, the Confidentiality Agreement, the F-Reorganization Documents (as defined in the JPI Merger Agreement), the JPI Merger Agreement, the GFI Merger Agreement and the GFI Support Agreement (as defined in the GFI Merger Agreement) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof and thereof.

        (b)   This Agreement shall be binding upon and inure solely to the benefit of each Party, and nothing in this Agreement, express or implied, is intended to or shall confer upon any Person not a party to this Agreement any rights, benefits or remedies of any nature whatsoever, except that the Financing Sources shall be express third party beneficiaries of Sections 5.16(g), 9.4(b) (where applicable to the Financing Sources), 9.6 (where applicable to the Financing Sources), 9.7 (where applicable to the Financing Sources), 9.9(b) and 9.9(d), each of such Sections shall expressly inure to the benefit of the Financing Sources and the Financing Sources shall be entitled to rely on and enforce the provisions of such Sections (in each case to the extent expressly applicable to them). The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. The representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties (other than the Financing Sources). Accordingly, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

        Section 9.5    Severability.    If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the Transactions are consummated as originally contemplated to the greatest extent possible.

        Section 9.6    Assignment.    Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of the other Parties, and any attempt to make any such assignment without such consent shall be null and void; provided that IDB Buyer shall have the right to assign its rights and interests under this Agreement to any Affiliate of IDB Buyer without the prior written consent of the other Parties; provided, further, however, that no such assignment shall otherwise vary or diminish any of IDB Buyer's rights or obligations under this Agreement; and provided, further,

49

that IDB Buyer shall have the right to assign its rights and interests (but not its obligations) under this Agreement by way of security to the Lenders without obtaining the prior consent of Seller. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns.

        Section 9.7    Amendment.    This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties; provided, however, that this proviso of this Section 9.7 and Sections 5.16(g), 9.4(b) (where applicable to the Financing Sources), 9.6 (where applicable to the Financing Sources), 9.9(b) and 9.9(d) (and any other provision of this Agreement to the extent an amendment, supplement, waiver or other modification of such provision would modify the substance of such Sections or provisions) that adversely affects any Financing Source may not be amended, supplement, waived or otherwise modified without the prior written consent of the Lenders, or any applicable agent of such Lenders with the consent of the requisite number of such Lenders; provided, further, that after the Closing neither JPI nor New JPI shall be required to sign or otherwise agree to any amendment of this Agreement.

        Section 9.8    Extension; Waiver.    At any time prior to the Closing, the Parties may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

        Section 9.9    Governing Law and Venue; Waiver of Jury Trial.    

        (a)   THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN, ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT REGARD TO ITS RULES OF CONFLICTS OF LAW THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY STATE OTHER THAN THE STATE OF DELAWARE. Except as set forth in Section 2.7 (Post-Closing Adjustment), the Parties hereby irrevocably submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, or, in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, the federal courts of the United States of America located in the State of Delaware in respect of all matters arising out of or relating to this Agreement the interpretation and enforcement of the provisions of this Agreement, and of the documents referred to in this Agreement, and in respect of the Transactions, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the Parties irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined exclusively in such courts. The Parties hereby consent to and grant any such court jurisdiction over the person of such Parties solely for such purpose and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.1 (Notices) or in such other manner as may be permitted by Law shall be valid and sufficient service thereof.

        (b)   Notwithstanding anything herein to the contrary, each Seller Related Party and each of the other Parties (i) agrees that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source in any way relating to this Agreement or any of the

50

transactions contemplated by this Agreement, including but not limited to any dispute arising out of or relating in any way to the Debt Financing, the performance thereof or the transactions contemplated thereby, in any forum other than exclusively in the Supreme Court of the State of New York, County of New York, or, if under applicable law exclusive jurisdiction is vested in the federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof), (ii) submits for itself and its property with respect to any such action to the exclusive jurisdiction of such courts, (iii) agrees that service of process, summons, notice or document by registered mail addressed to it at its address provided in Section 9.1 (Notices) shall be effective service of process against it for any such action brought in any such court, (iv) waives and hereby irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of, and the defense of an inconvenient forum to the maintenance of, any such action in any such court, and (v) agrees that a final judgment in any such action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

        (c)   EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.9(c).

        (d)   NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, EACH SELLER RELATED PARTY AND EACH OTHER PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS OF TRIAL BY JURY IN ANY ACTION, PROCEEDING, CLAIM OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE DEBT FINANCING OR ANY OF THE OTHER TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, WITH RESPECT TO ANY ACTION, PROCEEDING, CLAIM OR COUNTERCLAIM AGAINST ANY FINANCING SOURCE.

        Section 9.10    Enforcement.    The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate the transactions contemplated by this Agreement) in accordance with its specified terms or otherwise breach such provisions. Accordingly, the Parties acknowledge and agree that the Parties (on behalf of themselves and the third-party beneficiaries of this Agreement provided in Section 9.4(b) (Third Party Beneficiaries)) shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that any other party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. Any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce

51

        Section 9.12    CME Guaranty.    

        (a)   CME irrevocably, absolutely and unconditionally guarantees to IDB Buyer each and every obligation and liability of Seller hereunder, and the full and timely payment and performance of Seller's obligations hereunder, in each case through the Closing (the "Seller Guaranteed Obligations"). This is a guarantee of payment and performance, and not merely of collection, and CME acknowledges and agrees that this guarantee is full and unconditional, and no release or extinguishment of Seller's obligations or liabilities under this Agreement, whether by decree in any bankruptcy proceeding or otherwise, shall affect the continuing validity and enforceability of this guarantee. CME hereby waives,

52

for the benefit of IDB Buyer, (i) any right to require IDB Buyer, as a condition of payment or performance by CME under this Section 9.12, to proceed against Seller or pursue any other remedies whatsoever, (ii) to the fullest extent permitted by Law, any defenses or benefits that may be derived from or afforded by Law that limit the liability of or exonerate guarantors or sureties, (iii) any and all promptness, diligence, notice of the creation, renewal, extension or accrual of any of the Seller Guaranteed Obligations and notice of or proof of reliance by IDB Buyer upon this guarantee or acceptance of this guarantee and (iv) any claim, right (including right of set-off), deduction or defense of any kind that Seller may have or may assert under this Agreement. CME understands that IDB Buyer is relying on this guarantee in entering into this Agreement.

        (b)   Without limiting the generality of the foregoing, CME authorizes Seller in its sole and absolute discretion, without any notice to or consent of CME and without in any way discharging, terminating, releasing, affecting or impairing the obligations of CME hereunder, to (i) amend, modify, extend or accelerate the time or manner of payment for or performance of the Seller Guaranteed Obligations or otherwise amend or modify any other terms of provisions of this Agreement in accordance with its terms, (ii) release, discharge, compromise or make any settlement with IDB Buyer in respect of the Seller Guaranteed Obligations or (iii) exercise any right or power conferred in this Agreement, or fail or omit to enforce any such right or power, or waive any covenant or condition therein provided or any default thereunder.

        (c)   CME represents and warrants to IDB Buyer that (i) it has full corporate power and authority to enter into this Agreement and to perform its obligations hereunder, (ii) the execution and delivery by CME of this Agreement has been duly authorized by all necessary corporate action and no other proceedings are necessary to authorize the execution and delivery of this Agreement, and (iii) this Agreement has been duly and validly executed and delivered by CME and, assuming due authorization and delivery by the other Parties, is a valid and binding agreement, enforceable against CME in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws of general applicability relating to or affecting creditors' rights and to general equity principles.

GFI has delivered or made available to CME true, correct and complete copies of the minutes of, and resolutions approved and adopted at, all meetings of the Board of Directors of GFI held since January 1, 2011 through the date of this Agreement other than minutes related to the Transactions.

        Section 3.2    Subsidiaries.

        Section 3.12    Litigation.     As of the date hereof, (a) there is no Proceeding pending, threatened in writing, or, to the Knowledge of GFI, threatened against GFI or any T&F Subsidiary, or their respective properties or rights or any of their respective current or former directors, officers, employees or contractors (in their capacities as such or relating to their services or relationship to GFI) except as do not constitute a Material Adverse Effect, (b) there is no Order of any Governmental Entity, Self-Regulatory Organization or arbitrator outstanding against GFI or any T&F Subsidiary except as do not constitute a Material Adverse Effect and (c) there is no Proceeding pending or, to the Knowledge of GFI, threatened against GFI or any Subsidiary of GFI, which seeks to, or would reasonably be expected to, restrain, enjoin or delay the consummation of any of the Transactions or which seeks damages in connection therewith, and no injunction of any type has been entered or issued.

        Section 3.13    Compliance with Laws.     

        (a)   Except as do not constitute a Material Adverse Effect, (i) each of GFI and the T&F Subsidiaries hold all material permits, licenses, variances, exemptions, certificates, consents, Orders, approvals or other authorizations from any Governmental Entities and Self-Regulatory Organizations which are required for the lawful conduct of their respective businesses or ownership of their respective assets and properties (the "GFI Permits"), (ii) all GFI Permits are in full force and effect and none of the GFI Permits have been withdrawn, revoked, suspended or cancelled nor is any such withdrawal, revocation, suspension or cancellation pending or, to the Knowledge of GFI, threatened and (iii) each of GFI and the T&F Subsidiaries is, and since January 1, 2011, has been in compliance with the terms of the GFI Permits.

For purposes of this Section 3.13, "principal executive officer" and "principal financial officer" shall have the meanings given to such terms in the Sarbanes-Oxley Act. Since January 1, 2011, GFI has complied in all material respects with the provisions of the Sarbanes-Oxley Act.

        (d)   GFI maintains a system of "internal control over financial reporting" (as defined in Rule 13a-15(f) of the Exchange Act) that complies in all material respects with the requirements of the Exchange Act and has been designed by, or under the supervision of, its principal executive officer and principal financial officer, or Persons performing similar functions, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

64

Plan and none of the Transactions shall cause such assets or insurance obligations to be materially less than such benefit obligations; and (iii) each Foreign GFI Benefit Plan required to be registered has been registered and has been maintained in good standing with applicable regulatory authorities (including tax authorities). Section 3.16(l) of the GFI Disclosure Letter separately identifies each Foreign GFI Benefit Plan that is a defined benefit pension plan.
