(“Lehman”), Lehman Commercial Paper Inc. (“LCPI”), and Lehman Brothers Commercial Bank (together with LCPI, “Lehman Lenders”), and KKR Capital Markets LLC (“KCM” and, together with GSCP, CGMI, Lehman and Lehman Lenders, the “Commitment Parties,” “we” or “us”) that the Borrower intends to, directly or indirectly, acquire substantially all of the outstanding equity interests of GL Trade S.A., a French company (the “Acquired Company”) and to consummate the other Transactions (as defined in Exhibit A attached hereto) described in the transaction description attached hereto as Exhibit A (the “Transaction Description”). Capitalized terms used but not defined herein have the meanings assigned to them in the Transaction Description and the Bridge Facility Summary of Terms and Conditions attached hereto as Exhibit B (the “Term Sheet”). “Citigroup” shall mean Citigroup Global Markets Inc. (“CGMI”), Citibank, N.A., Citicorp USA, Inc., Citicorp North America, Inc. and/or any of their affiliates as CGMI shall determine to be appropriate to provide the services contemplated herein.

In connection with the Transactions, each of GSCP, CGMI (on behalf of Citigroup), Lehman Lenders and KCM (in such capacity, collectively, the “Initial Lenders”) is pleased to advise you of its several, but not joint, commitment to provide the percentage of the entire aggregate principal amount of the Facility as set forth in Schedule A hereto, upon the

terms and subject to the conditions expressly set forth or referred to in this Commitment Letter and in the Term Sheet.

You hereby appoint (a) GSCP and CGMI to act, and each of GSCP and CGMI hereby agree to act, as joint lead arrangers for the Facility and (b) GSCP, CGMI, and Lehman to act, and GSCP, CGMI, and Lehman hereby agree to act, as joint bookrunners for the Facility (in such capacity, the “Joint Bookrunners”). It is agreed that GSCP shall have “left” placement in any and all marketing materials or other documentation used in connection with the Facility and shall hold the leading role and responsibilities conventionally associated with such “left” placement, including maintaining sole “physical books” in respect of the Facility. It is agreed that no other arrangers, bookrunners, agents or co-agents will be appointed without the approval of each Commitment Party and no Lender (as defined below) will receive compensation with respect to the Facility outside the terms contained herein and in the letter of even date herewith addressed to you providing, among other things, for certain fees relating to the Facility (the “Fee Letter”), in each case unless you and we so agree.

The Initial Lenders reserve the right, prior to or after the execution of definitive documentation for the Facility (the “Financing Documentation”), to syndicate all or a portion of the Initial Lenders’ several commitments hereunder to one or more banks, financial institutions or other institutional lenders reasonably acceptable to us (after consultation with you and the Sponsors (as defined in that certain Credit Agreement, dated as of August 11, 2005 (as amended, the “Credit Agreement”), among SunGard Holdco LLC, among Solar Capital Corp., the Overseas Borrowers (as defined therein) party thereto, the Borrower, the lenders from time to time party thereto, and JPMorgan Chase Bank, N.A., as administrative agent)) that will become parties to the Financing Documentation pursuant to a syndication to be managed by us (after consultation with you and the Sponsors) (the banks, financial institutions and other institutional lenders becoming parties to the Financing Documentation, together with the Initial Lenders, being collectively referred to as the “Lenders”); provided that, the Initial Lenders agree that no Initial Lender will syndicate to those banks, financial institutions or other institutional lenders identified by you or any Sponsor in writing (including by email) prior to the date hereof; provided, further, that notwithstanding each Initial Lender’s right to syndicate the Facility and receive commitments with respect thereto, (a) no assignment of commitments of any Initial Lender prior to the date of the funding of the Facility (the “Closing Date”), shall reduce such Initial Lender’s obligation to fund its entire commitment in the event any assignee of such Initial Lender shall fail to do so on the Closing Date, and (b) each Initial Lender shall retain exclusive control over all rights and obligations with respect to its commitment, including all rights with respect to consents, modifications and amendments under the Facility until the Closing Date.

You agree to use your commercially reasonable efforts to assist the Joint Bookrunners in completing a syndication reasonably satisfactory to the Joint Bookrunners. You agree to actively assist us in achieving a timely syndication of the Facility, which we intend to conduct before the closing of the Facility (but which we reserve the right to conduct, and continue to conduct, after the closing of the Facility). Such assistance shall include (i) your using commercially reasonable efforts to ensure that the syndication efforts benefit materially from your existing banking relationships and the existing banking relationships of the Sponsors and the Borrower, (ii) your causing direct contact between your senior management,

representatives and advisors, on the one hand, and the proposed Lenders, on the other hand at mutually agreed upon times, (iii) your assistance in the preparation of a customary confidential information memorandum (the “Confidential Information Memorandum”) for the Facility and other customary marketing materials to be used in connection with the syndication (the “Information Materials”), (iv) the hosting, with the Joint Bookrunners, of a reasonable number of meetings to be mutually agreed upon of prospective Lenders at times and at a location to be mutually agreed upon, and (v) your using commercially reasonable efforts to obtain ratings from each of Standard & Poor’s Ratings Group (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”) for the Facility and update your corporate credit rating and corporate family rating from each of S&P and Moody’s, respectively. You understand that we may decide to commence syndication efforts for the Facility promptly after the date hereof. Without limiting your obligations to assist with syndication efforts as set forth above, each Initial Lender agrees that the successful completion of such syndication is not a condition to its commitment hereunder. To ensure an orderly and effective syndication of the Facility, you agree that until the earlier to occur of (a) the date that is one year after the Closing Date and (b) the successful placement of the Notes, there shall be no competing offering, placement or arrangement of any debt securities or other debt financing by you or any of your subsidiaries (other than (i) the Notes, (ii) the senior secured term loan financing contemplated by the other commitment letter, dated as of the date hereof, between you and us, (iii) any refinancing, replacement or other modification of the Borrower’s existing receivables facility, (iv) any ordinary course financings or refinancings by the Acquired Company permitted under the Acquisition Agreement or (v) if the Closing Date occurs, any borrowing of senior secured loans under the Credit Agreement) without our prior written consent.

We will manage all aspects of the syndication, including, without limitation, selection of Lenders (after consultation with you and the Sponsors), determination of when the Joint Bookrunners will approach potential Lenders and the time of acceptance of the Lenders’ commitments, any naming rights, any title of agent or similar designations or roles awarded to any Lender, the final allocations of the commitments among the Lenders and the amount and distribution of fees among the Lenders. To assist the Joint Bookrunners in such syndication efforts, you agree to use your commercially reasonable efforts to provide promptly to us all customary information reasonably available to you with respect to you, the Acquired Company and your and its subsidiaries and the Transactions, including, without limitation, all reasonably available financial information concerning you and the Acquired Company and projections relating to you and the Acquired Company and the Transactions (including financial estimates, forecasts and other forward-looking statements, the “Projections”), as we may reasonably request in connection with the syndication of the Facility.

You hereby acknowledge that certain prospective Lenders (such Lenders, “Public Lenders”; all other Lenders, “Private Lenders”) may have personnel that do not wish to receive “material non-public information” (within the meaning of the United States federal securities laws) with respect to you, the Acquired Company and your and their respective subsidiaries, or your or their respective securities (collectively, “MNPI”), and who may be engaged in investment and other market-related activities with respect to such entities’ securities. You agree, at our request, to prepare a version of the Confidential Information Memorandum and Information Materials to be used in connection with the syndication of the Facility (which will

be posted to IntraLinks or SyndTrak or by other similar electronic means), consisting exclusively of information and documentation that does not contain MNPI (the “Public Information Materials”). The parties hereto intend that the Public Information Materials will be substantially consistent with the information included in any offering memorandum for the offering of the Notes or in filings made with the Securities and Exchange Commission. Before distribution of any Information Materials (a) to prospective Private Lenders, you shall provide us with a customary letter authorizing the dissemination of the Information Materials and exculpating us with respect to any liability related to the use of the contents (and exculpating you, the Sponsors and the Acquired Company in the event of any unauthorized use) of the Information Materials by the recipients thereof and (b) to prospective Public Lenders, you shall provide us with a customary letter authorizing the dissemination of the Public Information Materials and confirming the absence of MNPI therefrom and exculpating us with respect to any liability related to the use of the contents (and exculpating you, the Sponsors and the Acquired Company in the event of any unauthorized use) of the Information Materials by the recipients thereof. In addition, you shall identify Public Information Materials by clearly and conspicuously marking the same as “PUBLIC”.

You agree that the Commitment Parties on your behalf may distribute the following documents to all prospective Lenders: (a) administrative materials for prospective Lenders such as lender meeting invitations, allocations and funding and closing memoranda, (b) the Term Sheet and notifications of changes to the terms of the Facility, (c) drafts and final versions of the Financing Documentation and (d) other materials intended for prospective Lenders after the initial distribution of the Information Materials. Notwithstanding the foregoing, if you so advise the Commitment Parties in writing (including by email) within a reasonable time prior to their intended distribution that any materials described in clause (d) above should only be distributed to prospective Private Lenders, then the Commitment Parties will not distribute such materials to Public Lenders without further discussions with you.

You hereby represent and warrant that (a) all written information concerning you and your subsidiaries, and, to the best of your knowledge all written information concerning the Acquired Company and its subsidiaries, other than the Projections and information of a general economic or industry nature (collectively, the “Information”) that has been or will be made available to any Commitment Party by you, the Acquired Company or any of your or its respective subsidiaries or by any of your or its respective representatives (including, without limitation, the Sponsors) on your behalf is and will be when furnished, taken as a whole, accurate in all material respects and does not and will not when furnished, taken as a whole, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which such statements are made, not materially misleading and (b) the Projections that have been or will be made available to any Commitment Party by you or any of your or its subsidiaries or by any of your or its representatives (including, without limitation, the Sponsors) on your behalf have been and will be prepared in good faith based upon assumptions believed by you to be reasonable at the time of preparation thereof and at the time the related Projections are made available to the Commitment Parties; it being understood that such financial projections are subject to significant uncertainties and contingencies, many of which are beyond your control, that no assurance can be given that any particular financial projections will be realized, that actual results may differ and that such

differences may be material. If, at any time prior to the earlier to occur of (i) the successful syndication of the Facility and (ii) the date that is 30 days after the Closing Date, you become aware that any of the representations and warranties in the preceding sentence would be incorrect in any material respect if the Information and Projections were being furnished, and such representations were being made, at such time, you agree to supplement the Information and the Projections, such that the representations and warranties in the preceding sentence remain true in all material respects; provided that Borrower shall have no obligation to update Projections after the Closing Date. In arranging the Facility, including the syndication of the Facility, each of the Commitment Parties will be entitled to use and rely primarily on the Information and the Projections without responsibility for independent verification thereof.

As consideration for the Initial Lenders’ several commitments hereunder and the Joint Bookrunners’ agreement to syndicate the Facility, you agree to pay (or to cause to be paid) to the Initial Lenders and the Joint Bookrunners the fees as set forth in the Term Sheet and in the Fee Letter. Once paid, such fees shall not be refundable under any circumstances.

The Initial Lenders’ several commitments hereunder and the Joint Bookrunners agreements to perform the services described herein are subject to (a) the execution and delivery of Financing Documentation consistent with this Commitment Letter and the Term Sheet and, for any other provisions in the Financing Documentation not addressed in the Term Sheet, consistent with similar bridge financing transactions with such changes as are mutually agreed in good faith to reflect the specific nature of the Acquisition (as defined in Exhibit A hereto) and (b) the other conditions set forth in the sections entitled “Conditions Precedent to Borrowing” in the Term Sheet.

Notwithstanding anything in this Commitment Letter, the Term Sheet, the Fee Letter, the Financing Documentation or any other letter agreement or other undertaking concerning the financing of the Transactions to the contrary, (a) the only representations and warranties relating to you, the Acquired Company, your and its subsidiaries and your and their businesses, the accuracy of which on the Closing Date shall be a condition to availability of the Facility on the Closing Date, shall be the Specified Representations (as defined below) and (b) the terms of the Financing Documentation shall be in a form such that they do not impair availability of the Facility on the Closing Date if the conditions set forth in the immediately preceding paragraph and in “Conditions Precedent to Borrowing” in Exhibit B have been satisfied. For purposes hereof, “Specified Representations” means (i) all the representations and warranties of the Acquired Company in the Acquisition Agreement (as defined in Exhibit A), the accuracy of which is a condition to your obligation to close the Acquisition and (ii) the representations and warranties in the Financing Documentation for the Facility relating to due organization of the direct holding company parent of the Borrower, the Borrower and the Guarantors, corporate power and authority (as they relate to due execution, delivery and performance of such Financing Documentation), due authorization, execution, delivery and performance of such Financing Documentation, enforceability of such Financing Documentation, solvency on the Closing Date of the Borrower and its restricted subsidiaries on a consolidated basis, no conflicts with applicable laws, charter documents or material debt agreements, status of the Facility as senior debt, Federal Reserve margin regulations and the Investment Company Act.

You agree (a) to indemnify and hold harmless each Commitment Party, its affiliates (other any Sponsor in its capacity as an equity holder or any Advisor (as defined below) in its capacity as such) and their respective partners, officers, directors, members, employees, agents, advisors and controlling persons (collectively, the “indemnified persons”), from and against any and all losses, claims, damages, liabilities and expenses, joint or several, that may be incurred by or awarded against any indemnified person arising out of or in connection with this Commitment Letter, the Term Sheet, the Fee Letter, the Transactions and the other transactions contemplated hereby, the Facility and the use of proceeds thereof or any claim, litigation, investigation or proceeding (any of the foregoing, a “Proceeding”) relating to any of the foregoing, regardless of whether any such indemnified person is a party thereto or whether a Proceeding is brought by a third party or by you or any of your affiliates, and to reimburse each such indemnified person upon demand for the reasonable fees and reasonable out-of-pocket expenses of one counsel to all such indemnified persons taken as a whole (and, if reasonably necessary, one local counsel in any relevant jurisdiction and, in the case of a conflict of interest, one additional counsel to the affected indemnified person and, if reasonably necessary, one additional local counsel to the affected indemnified person in any relevant jurisdiction) or other reasonable out-of-pocket expenses incurred in connection with investigating or defending any of the foregoing; provided that, the foregoing indemnity will not, as to any indemnified person, apply to losses, claims, damages, liabilities or related expenses to the extent they resulted from (i) the willful misconduct, bad faith or gross negligence of such indemnified person, its affiliates (excluding any Sponsor in its capacity as an equity holder of the Borrower or any Advisor in its capacity as such) or any of their officers, directors, employees, agents and controlling persons arising out of or in connection with this Commitment Letter, the Term Sheet, the Fee Letter, the Transactions and the other transactions contemplated hereby, the Facility and the use of proceeds thereof or any Proceeding relating to any of the foregoing (in any such case, as determined by a court of competent jurisdiction in a final and non-appealable judgment) or (ii) any material breach in bad faith of the obligations of such indemnified person or any of its affiliates under this Commitment Letter, the Term Sheet or the Fee Letter and (b) if the Closing Date occurs, to reimburse the Commitment Parties from time to time for all reasonable and documented out-of-pocket expenses (including, without limitation, due diligence investigation expenses, consultants’ fees (to the extent any such consultant has been hired with your prior consent (which consent shall not be unreasonably withheld)), syndication expenses, travel expenses and reasonable fees, disbursements and other charges of counsel identified in the Term Sheet (and a single local counsel in each relevant jurisdiction)) incurred in connection with the preparation of this Commitment Letter, the Term Sheet and the Fee Letter and the preparation of the Financing Documentation and related security documents (collectively, the “Expenses”) (provided, that if the Closing Date does not occur, you agree to reimburse us for any such Expenses actually incurred in an amount equal to the lesser of (A) the actual amount of Expenses incurred as of the date of expiration or termination of the commitments hereunder and (B) $200,000). If for any reason the foregoing indemnification is unavailable to the Commitment Parties or insufficient to hold it harmless, then you will contribute to the amount paid or payable by the Commitment Parties as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative economic interests of (i) you, the Sponsors and the Acquired Company and their respective affiliates, stockholders, partners or other equity holders on the one hand and (ii) the Commitment Parties on the other hand in the matters contemplated by this Commitment Letter, the Term Sheet and the Fee Letter, as well as the relative fault of (i) you, the Sponsors

and the Acquired Company and their respective affiliates, stockholders, partners or other equity holders and (ii) the Commitment Parties with respect to such loss, claim, damage or liability and any other relevant equitable considerations. Your reimbursement, indemnity and contribution obligations under this paragraph will be in addition to any liability which you may otherwise have, will extend upon the same terms and conditions to any affiliate of the Commitment Parties and the partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Commitment Parties and any such affiliate, and will be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of you, the Commitment Parties, any such affiliate and any such person. You also agree that neither any indemnified party nor any of such affiliates, partners, directors, agents, employees or controlling persons will have any liability to you, the Sponsors or the Acquired Company or any person asserting claims on behalf of or in right of you, the Sponsors or the Acquired Company or any other person in connection with or as a result of either this arrangement or any matter referred to in this Commitment Letter, the Term Sheet or the Fee Letter, except to the extent that any losses, claims, damages, liabilities or expenses incurred by you or your affiliates, stockholders, partners or other equity holders have been found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from (i) the willful misconduct, bad faith or gross negligence of such indemnified person, its affiliates (excluding any Sponsor in its capacity as a equity holder of the Borrower or any Advisor in its capacity as such) or any of their officers, directors, employees, agents and controlling person arising out of or in connection with this Commitment Letter, the Term Sheet, the Fee Letter, the Transactions and the other transactions contemplated hereby, the Facility and the use of proceeds thereof or any Proceeding relating to any of the foregoing (in any such case, as determined by a court of competent jurisdiction in a final and non-appealable judgment) or (ii) any material breach in bad faith of the obligations of such indemnified person or any of its affiliates under this Commitment Letter, the Term Sheet or the Fee Letter. Notwithstanding any other provision of this Commitment Letter, no Commitment Party shall be liable for any damages arising from (i) the use by others of information or other materials obtained through electronic, telecommunications or other information transmission systems, except to the extent such damages have resulted from the willful misconduct, bad faith or gross negligence of such party or any of its affiliates or related parties (as determined by a court of competent jurisdiction in a final and non-appealable judgment) or (ii) for any special, indirect, consequential or punitive damages in connection with its activities related to the Commitment Letter, the Term Sheet or the Fee Letter. Notwithstanding the foregoing, the indemnity obligations in this paragraph shall not apply to any losses, claims, damages, liabilities or expenses of any Commitment Party or affiliate thereof to the extent such loss, claim, damage, liability or expense arises solely as a result of a separate advisory engagement with such Commitment Party or its affiliate, in each case, acting in such capacity pursuant to such engagement (in such capacity, an “Advisor”).

None of the Commitment Parties and their affiliates will use confidential information obtained from you, the Acquired Company or the Sponsors by virtue of the transactions contemplated by this Commitment Letter or any of their other respective relationships with you, the Acquired

Company or the Sponsors in connection with the performance by them and their respective affiliates of services for other companies, and none of the Commitment Parties and their affiliates will furnish any such information to other companies, except to the extent otherwise permitted hereby.

You further acknowledge and agree that you are responsible for making your own independent judgment with respect to such transactions and the process leading thereto. You agree that you will not claim that any Commitment Party has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to you, in connection with such transaction or the process leading thereto. In addition, each Commitment Party may employ the services of its affiliates in providing certain services hereunder and may exchange with such affiliates information concerning you, the Sponsors, the Acquired Company and other companies that may be the subject of this arrangement, and such affiliates will be entitled to the benefits afforded to the Commitment Parties hereunder.
