This Transition License Agreement (“Agreement”) is effective as of the 31st day of March 2005, by and between, Reuters SA, a Swiss corporation located at 153 route de Thonon, 1245 Collonge-Bellerive, Switzerland (“Licensor”) on the one hand, and Bridge Trading Company, a Delaware corporation located at 788 Office Parkway, Creve Coeur, Missouri (“Licensee”) and Instinet Group Incorporated (“Parent”) on the other hand (Licensor, Licensee and Parent are sometimes referred to in this Agreement as the “Parties”).

WHEREAS, each of Licensor and Licensee desires to enter into this Agreement;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

Article 1. Grant of Right . During the Term, Licensor hereby grants to Licensee a non-exclusive, royalty-free license to use the trademarks and trade names “Bridge Trading,” “Bridge Trading Company” and the domain name “trading.bridge.com” (the “Names”) for use solely in connection with, and solely in the same countries and jurisdictions as, the business as currently conducted by Cyclone (as defined in the Stock Purchase Agreement dated as of February 28, 2005 among Parent, Reuters C LLC and Reuters Limited (the “Stock Purchase Agreement”)). All rights not hereby expressly granted to Licensee are reserved to Licensor. Without limiting the foregoing and for the avoidance of doubt, Licensee may use the Names pursuant to the above license in combination with any trademarks owned by Licensee or Parent as of the date of the Stock Purchase Agreement.

Article 2. Form of Use. Except as required by law or regulation and except as expressly permitted in Article 1, Licensee agrees not to use the Names in connection or combination with any third-party name, logo, trademark, service mark, inscription or designation without Licensor’s prior written approval. Except as expressly permitted in Article 1, Licensee shall at no time adopt or use any variation of the Names or any word or mark similar to or confusing with the Names without Licensor’s prior written consent. Licensee agrees to include on all displays of the Names to third parties all notices and legends required by applicable law or regulations to preserve and protect all of Licensor’s right, title and interest in, to and under the Names.

Article 3. Ownership of Names.

Section 3.1. Licensee and Parent agree that Licensor is the sole and exclusive owner of all rights, title and interest in the Names and any rights related thereto.

Section 3.2. The Parties agree that any and all goodwill arising from Licensee’s use of the Names shall inure solely to the benefit of Licensor, and neither during the Term nor after the termination of this Agreement shall Licensee or Parent assert any claim to the Names or such goodwill.

Section 3.3. The provisions of this Article 3 shall survive any termination of this Agreement.

Article 4. Quality Control. Licensee agrees to maintain and preserve the quality of (i) the uses of the Names and (ii) the goods and services in connection with which the Names are used, consistent with the current high standards and reputation for quality associated with the Licensor and the business of Licensee. Upon reasonable request by Licensor, Licensee shall (and Parent shall cause Licensee to) furnish to Licensor for its inspection samples of advertising and promotional materials and other documents, including access to the Licensee’s website, that bear or are used in connection with the Names.

Article 5. Approvals. Licensee shall, at its sole expense, comply at all times with all applicable laws and regulations pertaining to the conduct of the business symbolized by the Names, and obtain all appropriate permits and approvals, including without limitation government approvals.

Article 6. Notification for Non-Use. The Licensor shall notify the Licensee in the event Licensor intends to cease using the Names for a period of more than one hundred fifty (150) days.

Article 7. Term. The term of this Agreement (the “Term”) commences on the date hereof and lasts until the earlier of December 31, 2005 or the date on which termination occurs pursuant to Article 8.

Article 8. Termination.

Section 8.1. Licensee may terminate this Agreement at any time at its sole discretion.

Section 8.2. Licensor has the right to terminate this Agreement if Licensee commits a material breach of its obligations hereof, including without limitation a breach of Article 2 (Form of Use), Article 3 (Ownership of Names), Article 4 (Quality Control), or Section 11.4 (Succession and Assignment), and fails to cure such breach within thirty (30) days’ written notice by Licensor.

Section 8.3. Licensor has the right to terminate this Agreement immediately upon written notice to Licensee if (i) Licensee makes an assignment for the benefit of creditors; (ii) Licensee admits in writing its inability to pay debts as they mature; (iii) a trustee or receiver is appointed for a substantial part of Licensee’s assets; or (iv) to the extent termination is enforceable under the U.S. Bankruptcy Code, a proceeding in bankruptcy is instituted against Licensee which is acquiesced in, is not dismissed within one hundred twenty (120) days, or results in an adjudication of bankruptcy. If such event occurs, Licensor shall have the right, in addition to its other rights and remedies, to suspend Licensee’s rights regarding the Names while Licensee attempts to remedy the situation.

2

Section 8.4. Upon termination, Licensor and Licensee shall cooperate so as best to preserve the value of the Names, and Licensee shall immediately discontinue all use of the Names, and at Licensor’s request, destroy or return any materials related to same.

Article 9. Infringement. Licensee may not file any action, suit or proceeding (“Action”) alleging infringement, dilution, or other misuse (“Infringement”) of the Names without the prior written approval of Licensor, such approval to not be unreasonably withheld or delayed. Without limiting the foregoing, it shall not be deemed unreasonable for Licensor to withhold its approval with respect to such an Action if Licensor reasonably believes such an Action may cause its trademark rights in the Names and/or the “Bridge” trademark to be found invalid or unenforceable. Licensor may in its absolute discretion file an Action alleging Infringement of the Names without the consent of Licensee provided that for Infringement within the scope of Licensee’s licensed rights hereunder, Licensor shall give Licensee notice and the right to consult in any such Action.

Article 10. Representations. Licensor hereby represents and warrants to Licensee as follows: (i) Licensor is a corporation duly organized and validly existing under the laws of Switzerland. Licensor has all requisite power and authority to enter into this Agreement and to perform its obligations hereunder; (ii) the execution, delivery and performance by Licensor of this Agreement and the consummation by Licensor of the transactions contemplated hereby have been duly authorized and approved by all necessary corporate action. This Agreement has been duly executed and delivered by Licensor and, assuming that this Agreement is a legal, valid and binding obligation of each of the other Parties hereto, is a legal, valid and binding obligation of Licensor, enforceable against Licensor in accordance with its terms.
